epithelial injury and TI fibrosis tif within a hypoxic microenvironment are associated with progressive loss of renal function in chronic kidney disease ckd transforming growth factor beta tgfβ is an important mediator of renal fibrosis growing evidence suggests that vitamin d ohd and its analogues may have a renoprotective effect in ckd here we examined the protective effect of the vitamin d analogue paricalcitol pc norαβtrihydroxysecoergostaze etriene on the responses of human LLC-PK1 cells to tgfβ pc attenuated tgfβinduced smad phosphorylation and upregulation of the notch ligand jagged αsmooth SMA and thrombospondin and prevented the tgfβmediated loss of ecadherin to mimic the hypoxic milieu of ckd we cultured renal epithelial cells in hypoxia o and observed similar attenuation by pc of tgfβinduced fibrotic responses furthermore in cells cultured in normoxia o pc induced an accumulation of hypoxiainducible transcription factors hif α and hifα in a time and concentration µm µm dependent manner here pcinduced hif stabilisation was dependent on activation of the pikinase pathway this is the first T0 to demonstrate regulation of the hif pathway by pc which may have importance in the mechanism underlying renoprotection by pc | MEDAL |
simple and regular anatomical structure is a hallmark of the cerebellar SC parasagittally arrayed alternate expression of aldolase czebrin ii in PCs pcs has been extensively studied but surprisingly little is known about its PET significance here we found a precise structurefunction relationship between ALD c expression and synchrony of pc complex spike MICs that reflect climbing fiber inputs to pcs we performed twophoton calcium imaging in transgenic mice in which aldolase c compartments can be visualized in vivo and identified highly synchronous complex spike MICs among aldolase cpositive or ALD cnegative pcs but not across these populations the boundary of aldolase c compartments corresponded to that of complex spike synchrony at singlecell resolution sensory stimulation evoked aldolase c compartmentspecific complex spike responses and synchrony this result further revealed the structurefunction segregation in awake animals complex spike synchrony both within and between pc populations across the aldolase c boundary were enhanced in response to sensory stimuli in a way that two functionally distinct pc ensembles are coactivated these results suggest that pc populations characterized by ALD c expression precisely represent distinct functional units of the cerebellar cortex and these functional units can cooperate to process sensory information in awake animals | MEDAL |
distributions of two different subclasses of intermediate filaments vimentin and glial filaments were studied immunohistochemically in human BT using TPS AS to each protein S1 vimentin and astroprotein gfap surgical specimens meningiomas ependymomas benign astrocytomas anaplastic astrocytomas and GBMs were fixed in ethanol or ethanolacidic acid and embedded in paraffin avidin biotin peroxidasecomplex abc method vectastain was carried out on micronsthick paraffin sections all meningioma cells were negative for astroprotein gfap and positive for vimentin ependymoma cells showed various patterns of immunoreaction for astroprotein gfap but were invariably positive for vimentin in benign astrocytomas many cells or cell body and processes were positive for astroprotein gfap immunoreaction for vimentin was however less frequent and intense in anaplastic astrocytomas population of astroprotein gfappositive cells decreased and vimentinpositive cells increased astroprotein gfappositive cells were further decreased in GBMs and the population of vimentinpositive cells varied among tissues the present T0 suggests that the anaplastic NC of astrocytoma cells were associated with decreased expression of glial filaments and increased expression of vimentin filaments it was also suggests that the expression of both intermediate filaments may be suppressed in highlymalignant glial tumor cells | MEDAL |
using radioligand IB techniques we determined the equilibrium dissociation constants kds for a series of ADs at the histamine h muscarinic acetylcholine alpha and alpha adrenergic and dopamine d receptors of normal human brain tissue obtained at autopsy twentyfive different antidepressants were studied at all but the d receptor at which the number was including a metabolite of an antidepressant of all the receptor interactions studied that at the histamine h receptor was in GA the most potent interaction of this class of compounds corresponding to results from studies using animal tissue as the source of receptors at the human BB histamine h receptor ADs remained among the most potent histamine h antagonists known although their affinities for human receptors were lower than those for animal receptors the most potent and the least potent EDC at the receptors were doxepin kd nm and fluvoxamine kd microm at the histamine h receptor amitriptyline kd nm and trazodone kd microm at the muscarinic receptor doxepin kd nm and viloxazine kd microm at the alpha receptor mianserin kd nm and BUP kd microm at the alpha receptor and amoxapine kd nm and trazodone kd nm at the d receptor respectively in general compared to older drugs the newer EDC tended to have lower affinities for these receptors | MEDAL |
the attentional blink ab describes a timebased deficit in processing the second of two masked targets the ab is att if successive targets appear between the first and final target or if a cueing target is positioned before the final target using various speeds of stimulus presentation the current study employed successive targets and cueing targets to confirm and extend an understanding of targettarget cueing in the ab in experiment three targets were presented sequentially at rates of msecitem or msecitem successive targets presented at msec improved performance compared with nonsuccessive targets however accuracy was equivalently high for successive and nonsuccessive targets presented at msecitem suggesting thatregardless of whether they occurred consecutivelythose items fell within the temporally defined attentional window initiated by the first target using four different presentation speeds experiment confirmed the timebased definition of the ab and the success of targetcueing at msecitem this experiment additionally revealed that cueing was most effective when resources were not devoted to the cue thereby implicating capacity limitations in the ab across both experiments a novel ordererror measure suggested that PE tend to decrease with an increasing duration between the targets but also revealed that certain stimulus conditions result in stable order accuracy overall the results are best encapsulated by targetbased and resourcesharing theories of the ab which collectively value the contributions of capacity limitations and optimizing transient attention in time | MEDAL |
the ultimate objective of nanoparticlebased therapy is to functionalize nanomedicines in a microdisease environment without any SE here we reveal that our phresponsive nitroxide radicalcontaining nanoparticles rnpph disintegrate within the renal acidic lesion and act as scavengers of reactive oxygen species ros leading to a relief of acute kidney injury aki rnpph was prepared using amphiphilic block copolymers possessing tetramethylpiperidinenoxyl tempo moieties via amine linkage as a side chain of the hydrophobic segment the selfassembled rnpph disintegrated at ph below because of a protonation of the amino groups in the hydrophobic core of the nanoparticles thereby resulting in an improvement in ros scavenging activity using a renal ischemiareperfusion aki MM in mice the therapeutic effect of rnpph on ros damage was evaluated unlike the rnp without phtriggered disintegration rnpnonph the rnpph showed extremely high ros scavenging activity and renal protective effects it is interesting to note that the side effect of nitroxide radicals was markedly suppressed due to the compartmentalization of nitroxide radicals in the core of rnpph in untargeted area the morphology changes in rnpph were confirmed by analyzing electron spin resonance spectra and these findings provide the evidence of the real therapeutic effect of the environmentsensitive specific disintegration of nanoparticles in vivo | MEDAL |
CS has been shown to cause endothelial dysfunction to examine the effects of VC and CS on endotheliumdependent vasodilation we measured the lumen diameter and flow velocity of the brachial arteries at rest during reactive hyperemia following transient AO and after sublingual nitroglycerin mg in smokers n and nonsmokers n with highresolution ultrasound after infusion of saline or saline plus VC mgmin for min we also performed the same study in smokers n before and min T3 CS in addition we measured the SS C2 of VC and the plasma C2 of thiobarbituric acidreactive substances tbars as an index of lipid peroxidation the smokers had lower vitand ii respectively there was a significant difference between the two screening systems in the age distribution of the examinees the detection rates of breast cancer were and in systems i and ii respectively which are times higher than that obtained by conventional screening using PE CT the detection rate increased especially in the sixth and seventh decades of life the sensitivity of mammography screening was in system i and in system ii higher sensitivity than that of screening by PE was obtained in women aged over the proportion of stage i was in system i and in system ii compared with in the united states and europe the rates of no nodal involvement were high being and in systems i and ii respectively compared with in other countries BCT was applied to of the patients with breast CA detected by the two screening systems in addition in wolfes classification of mammograms the proportion of dy mammary dysplasia DP was remarkably low being in the sixth decade and in the seventh decade compared with in women aged years these results indicate that mammographic screening is effective in women aged over years in japan as has been found in other countries | MEDAL |
rfdriven ion sources for accelerators and many industrial applications benefit from detailed numerical modeling and simulation of plasma characteristics for instance modeling of the spallation neutron source sns internal antenna h source has indicated that a C1 plasma velocity is induced near bends in the antenna where structural failures are often observed this could lead to improved designs and ion source performance based on simulation and modeling however there are significant separations of time and spatial scales inherent to rfdriven plasma ion sources which makes it difficult to model ion sources with explicit kinetic particleincell pic simulation codes in particular if both electron and ion motions are to be explicitly modeled then the simulation time step must be very small and total simulation times must be large enough to capture the evolution of the plasma ions as well as extending over many rf periods additional physics processes such as plasma chemistry and surface effects such as AA electron emission increase the computational requirements in such a way that even fully parallel explicit pic models cannot be used one alternative method is to develop fluidbased codes coupled with electromagnetics in order to model ion sources timedomain fluid models can simulate plasma evolution plasma chemistry and surface physics models with reasonable computational resources by not explicitly resolving electron motions which thereby leads to an increase in the time step this is achieved by solving fluid motions coupled with electromagnetics using reducedphysics models such as singletemperature magnetohydrodynamics mhd extended gas dynamic and hall mhd and twofluid mhd models we show recent results on modeling the internal antenna h ion source for the sns at oak ridge national laboratory using the fluid plasma modeling code usim we compare demonstrate plasma temperature equilibration in twotemperature mhd models for the sns source and present simulation results demonstrating plasma evolution over many rf periods for different plasma temperatures we perform the calculations in parallel on unstructured meshes using finitevolume solvers in order to obtain results in reasonable time | MEDAL |

gata is a transcription factor expressed both in the hematopoietic system and in the sertoli cells of the testis and is essential for correct erythropoiesis hematopoietic and sertoli cells transcribe gata from two different promoters the PT erythroid is AS in hematopoietic cells the distal testis is AS in sertoli cells we investigated by rtpcr the possibility that gata might be transcribed from the testis promoter also in hematopoietic cells testis promoterderived transcripts are present at low levels in vivo at all stages of hematopoietic development purified multipotent progenitors fractionated into populations expressing low or high C2 of gata do not contain any testis transcripts however when grown in vitro they rapidly express gata from the testis promoter in the presence of erythropoietin epo but not in that of other growth AF this result reflects an epodependent differentiation event rather than a direct effect of epo indeed immortalized CFU-GM lines which respond to both epo and scf continue to express testisderived transcripts when switched from epo to scf | MEDAL |
in young spontaneously hypertensive rats shr a preganglionic nervedependent elevation of choline AT chac and IMT hydroxylase th MICs was found in celiac ganglia as compared with those in young normotensive kyoto WR that was not present in superior cervical ganglia stellate ganglia and adrenal PG the rise in both enzyme activities in the celiac ganglion disappeared in AD shr an elevation of plasma norepinephrine and dopamine betahydroxylase levels found in prehypertensive shr a probable indication of IP sympathetic activation disappeared after the bilateral removal of the celiac ganglion however ganglionectomy did not change the subsequent OD of hypertension these results indicate that the faster maturation of the celiac ganglion and the end organs it innervates in yount shr are causally related to the activation of the IP sympathetic NS the peripheral sympathetic activation in young shr is regarded as a warning sign but this does not trigger the development of hypertension | MEDAL |
the low density lipoprotein receptorrelated proteinmegalin lrp is an endocytic receptor that is expressed on the apical surfaces of epithelial cells lining specific regions of the male and female reproductive tracts in the present T0 immunohistochemical staining revealed that lrp is also expressed by epithelial cells lining the ductal region and the ampulla of the rat seminal vesicle to identify lrp ligands in the seminal vesicle we probed seminal vesicle fluid with ilabeled lrp in a gelblot overlay CA a kda protein under nonreducing conditions was found to bind the radiolabeled receptor the protein was isolated and subjected to protease digestion and the proteolytic fragments were subjected to mass spectroscopic sequence analysis as a result the kda protein was identified as the seminal vesicle sec protein ii svsii a L1 constituent of the seminal coagulum using purified preparations of svsii and lrp solidphase IB assays were used to show that the svsii bound to the receptor with high affinity kd nm the binding of svsii to lrp was inhibited using a known antagonist of lrp CF the kda receptorassociated protein rap using a series of recombinant subfragments of svsii the lrp binding site was mapped to a stretch of repeated residue modules located in the central portion of the svsii polypeptide to evaluate the ability of lrp to mediate isvsii endocytosis and lysosomal degradation ligand clearance assays were performed using differentiated mouse f cells which express high levels of lrp radiolabeled svsii was internalized and degraded by the cells and both processes were inhibited by antibodies to lrp or by rap the results indicate that lrp binds svsii and can mediate its endocytosis leading to lysosomal degradation | MEDAL |
we wished to investigate the urodynamic characteristics and colonic motility in a group of children with severe chronic constipation and lower urinary tract symptoms we performed colonic manometry using an endoscopically placed catheter the urodynamic studies consisted of cystometry electromyography of the EUS measurement of urinary flow rate and urethral pressure profile we found abnormal colonic motility in all patients findings included absent gastrocolonic response n absent highamplitude propagated contractions hapcs n and abnormal propagation of hapcs n urodynamic features were abnormal in children findings included uninhibited bladder contractions n hypertonic bladder n sphincter dyssynergy n small capacity bladder n in all children constipation improved in three after a partial colectomy urinary symptoms persisted we conclude that some children with severe constipation may have a neuropathy affecting both the colonic and lower urinary tracts systems in this group of patients treatment of constipation does not result in resolution of urinary PS | MEDAL |

moxonidine is a mixed i imidazolinealphamoxonidinemorphine the i imidazoline preferring antagonist efaroxan produced a dosedependent antagonism of both MOX mgkg and clonidine mgkg in addition the alphaadrenergic receptor antagonist yohimbine produced a doserelated antagonism of moxonidine but only partially antagonized clonidine prazosin failed to block the effects of either moxonidine or clonidine indicating a lack of involvement of alpha as well as alphab and alphac receptors the present results suggest that alphaadrenergic receptors play an important role in mediating the effects of MOX in producing antinociception in the formalin test further the present results demonstrate that the mechanism of action of moxonidine and clonidine differ in that clonidine but not moxonidine produces an antinociceptive effect through a yohimbineinsensitive mechanism in the formalin test | MEDAL |

vulnerable or highrisk atherosclerotic plaques often exhibit large lipid cores and thin fibrous caps that can lead to deadly vascular events when they rupture in this T0 PE glycol pegmicelles that incorporate a gadolinium diethylenetriamine pentaacetic acid gddtpa amphiphile were used as an mr UCA in an approach inspired by lipoproteins the micelles were functionalized with tyrosine residues an aromatic lipophilic CAA to reach the lipidrich Az of atherosclerotic PI in a highly efficient manner these micelles were applied to apolipoprotein e apoe mice as a MM of atherosclerosis the ABD aortas of the animals were imaged using tweighted tw highresolution mri at t before and up to h T3 the administration of the micelles pegmicelles modified with IMT residues yielded a significant enhancement of the ABD aortic wall at and h PI pi as compared to unmodified micelles fluorescence microscopy on histological sections of the abdominal aorta showed a rho between lipidrich Az and the CSD of the functionalized UCA in plaque using a simple approach we demonstrated that lipidrich areas in AS PI of apoe mice can be detected by mri using gddtpa micelles | MEDAL |
SE of mongolian gerbils to trichloroethylene tce ppm in an inhalation chamber continuously for mo resulted in an altered HFA DP of phospholipid in discrete areas of the BB lipids were extracted from four brain regions the CBF cortex the hippocampus the cerebellar vermis posterior and the BS no changes induced by tce were found in lipid class distribution among the different regions examined whole BB weights and weights of the dissected pieces were also unchanged in EPG from the CBF SC and the hippocampus a decrease was found among longchain fatty acids derived from linolenic acid with a corresponding increase of the LA family the cerebellar vermis and the BS were less affected since Az rich in gray matter were affected more than those with a high proportion of WG matter it seems reasonable to assume that the fatty acid alterations of ethanolamine phosphoglycerides occur mainly in the gray matter furthermore we suggest that the alterations can be a compensatory mechanism for the membrane fluidizing properties of tce | MEDAL |
skin lipids of mice exposed to no contain lipidsoluble nitrosating agents nsa that react in vitro with amines to produce nitrosamines to test whether this reaction occurs in skin we exposed mice to ppm no for h and h later applied mg morpholine or nmethylaniline to the skin which was then analyzed for the corresponding nitrosamine when morpholine was applied mean nnitrosomorpholine yield was only nmolmouse not significant when nmethylaniline was applied and mice were killed after min nnitrosonmethylaniline yield in the skin was nmolmouse of which occurred in the hair nsa formation when mice were exposed to ppm no was only of that for exposure to ppm no nsa occurred mostly in surface lipids of the skin and its in vitro reaction to give nitrosamines was not inhibited by alphatocopherol when morpholine was painted and mice were then exposed to ppm no for min the skins contained nmol nnitrosomorpholinemouse attributed to a direct reaction between no and the amine we concluded that nitrosamine formation in skin by this direct reaction may be more important than the reaction of amines with noderived nsa | MEDAL |
in a retrospective study we compared TV sonograms with transabdominal sonograms in women referred for DUE of palpable pelvic masses the diagnoses included ovarian cyst endometrioma complex cyst four dermoid three infection three ovarian malignancy two and uterine fibroid three the final diagnosis was made surgically in patients and by a combination of US and clinical correlation in the remaining patients more information about the internal architecture or anatomy of the mass was provided by the TV images than by the transabdominal scans in of the patients transabdominal sonography did not provide more diagnostic information in any of the patients examined TVS was helpful in obese patients in those with a C1 amount of bowel gas and in those unable to achieve adequate bladder filling six simple cysts and four complex pelvic masses were identified solely on TV sonograms the results suggest that transvaginal US has considerable advantages over conventional TAS in the evaluation of pelvic masses in women | MEDAL |

the properties of the body surface play a crucial role in most interactions of marine organisms critical ecological properties such as drag morphology uptake and release of radiation and organic matter are linked to the BS of an aquatic organism the properties and functions of this interface may be modified substantially by the presence and MICs of epibiotic communities this in turn may lead to substantial modulation of the interactions between the organism bearing epiphytes and its environment with consequences for the relative fitness of the host organism basibiont and its interactors and ultimately the structure and SF-36 of the assemblage epibiosis may act as an ecological lever via these indirect effects greatly amplifying or buffering biotic and abiotic stress | MEDAL |

psi a nonclassical nucleoside present in human urine as a degradation product of rnas is one of the few molecules that has a glycosidic cc bond through a data base mining RPA involving transcriptomic data we have molecularly identified two enzymes that are involved in the metabolism of psi in uropathogenic escherichia coli the principal agent of urinary tract infections in humans the first enzyme coded by the gene yeic specifically phosphorylates pseudouridine to pseudouridine phosphate accordingly yeic mutants are unable to metabolize pseudouridine in contrast to wildtype e coli uti the second enzyme encoded by the gene yein belonging to the same operon as yeic catalyzes the conversion of psi phosphate to uracil and ribose phosphate in a divalent cationdependent manner remarkably the glycosidic cc bond of pseudouridine is cleaved in the course of this reaction indicating that yein is the first molecularly identified enzyme able to hydrolyze a glycosidic cc bond though this reaction is easily reversible the association of yein with psi kinase indicates that it serves physiologically to metabolize psi phosphate rather than to form it yein is homologous to thermotoga maritima inda a protein with a new fold which we now show to act also as a pseudouridinephosphate glycosidase data base mining indicates that most eukaryotes possess homologues of psi kinase and pseudouridinephosphate glycosidase and that these are most often associated in a single bifunctional protein the gene encoding this bifunctional protein is absent from the genomes of man and other mammals indicating that the capacity for metabolizing pseudouridine has been lost late in evolution | MEDAL |

cytochrome p cypa is the principal and most abundant human isoform of cyp responsible for the metabolism of more than of all consumed drugs and innumerable endogenous compounds expression of cypa is sexually dimorphic and regulated by the combined actions of gh and glucocorticoids in the case of the rat nearly all of the cyps are intrinsically or inherently sexually dimorphic meaning that the expressed sex differences are permanent and irreversible using primary hepatocyte cultures derived from men and women exposed to physiologiclike C2 of continuous gh the feminine circulating profile CT dexamethasone alone and the combined regimen we observed a dramatic inherent cypa sexual dimorphism women more than men with all treatments the molecular basis for this intrinsic sexually dimorphic expression of cypa appears to be due at least in part to a greater level of hormonedependent activation and nuclear translocation of both hepatocyte nuclear factorα hnfα and pregnane x receptor in female HCs furthermore these transcription factors exhibited significantly higher dna IB C2 to their TPS motifs on the cypa promoter in female hepatocytes inferring a possible explanation for the elevated expression of cypa in women accordingly experiments using hepg cells treated with small GABA rnainduced knockdown of hnfα andor transfected with luciferase reporter constructs containing a cypa promoter lacking hnfαbinding motifs demonstrated that gh to a greater extent dexamethasone and to the greatest extent the combine hormone regimen stimulated hnfα and pregnane x receptor promoter TA signifying enhanced transcription of cypa and thus identifying a molecular mechanism contributing to the intrinsic sexual dimorphic expression of human cypa | MEDAL |

oral microbiota consists of hundreds of different species of bacteria fungi protozoa and archaea important for oral health oral mycoses mostly affecting mucosae are mainly caused by the opportunistic pathogen CA they become relevant in denturewearers elderly people in diabetic patients and in immunocompromised individuals differently bacteria are responsible for other pathologies such as dental caries gingivitis and periodontitis which affect even immunecompetent individuals an appropriate oral hygiene can avoid or at least ameliorate such pathologies the regular and correct use of toothbrush toothpaste and mouthwash helps prevent oral infections interestingly little or no information is available on the effects if any of mouthwashes on the composition of oral microbiota in healthy individuals therefore by means of in vitro models we assessed the effects of alcoholfree commercial mouthwashes with different composition with chlorhexidine digluconate with fluoride with essential oils with cetylpyridinium chloride and with triclosan on several virulence traits of c albicans and a group of viridans streptococci commonly colonizing the oral cavity for the T0 here described a REF strain of c albicans and of streptococci isolates from pharyngeal swabs were used chlorhexidine digluconate and cetylpyridinium chloridecontaining mouthwashes were the most ERP in impairing c albicans capacity to adhere to both abiotic and biotic surfaces to elicit Th1 cytokine secretion by oral epithelial cells and to escape intracellular killing by phagocytes in addition these same mouthwashes were ERP in impairing biofilm formation by a group of viridans streptococci that notoriously cooperate with the cariogenic s mutans facilitating the establishment of biofilm by the latter differently these mouthwashes were ineffective against other viridans streptococci that are NK competitors of s mutans finally by an in vitro MM of mixed biofilm we showed that mouthwashestreated s salivarius overall failed to impair c albicans capacity to form a biofilm in conclusion the results described here suggest that chlorhexidine and cetylpyridiniumcontaining mouthwashes may be ERP in regulating microbial homeostasis of the oral cavity by providing a positive balance for oral health on the other side chlorhexidine has several side effects that must be considered when prescribing mouthwashes containing this molecule | MEDAL |
african clawed frogs xenopus laevis although primarily aquatic have a high tolerance for dehydration being capable of withstanding the loss of up to of total water body water recent studies have shown that micrornas play a role in the response to dehydration by the CL kidney and VP skin of x laevis micrornas act by modulating the expression of mrna transcripts thereby affecting diverse PSA pathways in this study micrornas were assessed in frog brains comparing control and dehydrated ± of total body water lost conditions micrornas of interest were measured using a modified protocol which employs polyadenylation of micrornas prior to reverse transcription and qpcr twelve micrornas that showed a significant decrease in expression to of control levels in brains from dehydrated frogs xlamira a b c e a and b were identified genomic analysis showed that the sequences of these dehydrationresponsive micrornas were highly conserved as compared with the comparable micrornas of mice suppression of these micrornas implies that translation of the mrna transcripts under their control could be enhanced in response to dehydration bioinformatic analysis using the diana mirpath program v predicted the top two kegg pathways that these micrornas collectively regulate axon guidance and longterm potentiation previous studies indicated that suppression of these micrornas promotes neuroprotective pathways by increasing the expression of brainderived neurotrophic factor and activating Bcl-2 pathways this suggests that similar actions may be triggered in x laevis brains as a protective response to dehydration | MEDAL |

endovascular redo aortic operations are a challenging undertaking techniques for treatment date almost as far back as the original or itself risk factors for failure following aortic repair include larger ABD aortic aneurysm necks severe neck angulation as well as clinical variables such as age family history obesity and chronic obstructive pulmonary disease the armamentarium of endovascular treatments is vast and increasing aside from provisional embolization of endoleaks or deferment to or conversion attention should be directed toward obtaining adequate proximal and distal sealing this can be achieved with palmaz stents endoanchors and extension with fenestrated or branched endovascular repair thoracic aortic coverage may be required and revascularization of the LSA should be considered technical issues such as these as well as target vessel cannulation and accommodation of the new graft within the previous implanted VG require experience and careful planning distal extension can likewise resolve a failing repair and this may require the use of internal iliac artery embolization or iliacbranch devices redo aortic operations are technically demanding and are carried out with increased risks improving technology such as F0 imaging should mitigate some of this risk and are recommended | MEDAL |
computerbased imaging systems are becoming important tools for quantitative assessment of peripheral blood and bone marrow samples to help experts diagnose blood disorders such as acute leukemia these systems generally initiate a segmentation stage where white blood cells are separated from the background and other nonsalient objects as the success of such imaging systems mainly depends on the accuracy of this stage studies attach great importance for developing accurate segmentation algorithms although previous studies give promising results for segmentation of sparsely distributed normal white blood cells only a few of them focus on segmenting touching and overlapping cell clusters which is usually the case when leukemic cells are present in this article we present a new algorithm for segmentation of both normal and leukemic cells in peripheral blood and bone marrow images in this algorithm we propose to model color and shape characteristics of WBCs by defining two transformations and introduce an efficient use of these transformations in a markercontrolled watershed algorithm particularly these domain TPS characteristics are used to identify markers and define the marking CF of the watershed algorithm as well as to eliminate false WG blood cells in a postprocessing step working on WG blood cells in peripheral blood and bone marrow images our experiments reveal that the proposed algorithm improves the segmentation performance compared with its counterparts leading to high accuracies for both sparsely distributed normal WBCs and dense leukemic cell clusters | MEDAL |
details of ion transporting CA in cystic fibrosis airway epithelium are now known the central hypothesis that excessive drying of the airway surfaces is a primary event that leads to all the manifestations of the RI in cystic fibrosis is not proved the hypothesis is however consistent with the known transporting abnormalities and is strengthened by the modest clinical improvement produced by a strategy designed to correct the transporting CA the discovery of the CFTR together with the presumed structure of the protein product provides a focal point that must eventually connect the PET CA with the genetic defect the cellular function of the cystic fibrosis transmembrane regulator must now be the major target in research on cystic fibrosis strategies for treatment based on known cellular and molecular CA are beginning to emerge but will be undoubtedly more focused once the responsibility of the cystic fibrosis transmembrane regulator is known | MEDAL |

atrial natriuretic peptide anp binds to the guanylyl cyclasea gca receptor found in tissues such as the kidney and adrenal gland resulting in marked elevations of the intracellular signaling molecule cgmp here gca is shown to exist as a phosphoprotein when expressed in human embryonic cells the p is principally associated with phosphoserine with only trace amounts of phosphothreonine the addition of anp causes a timedependent dephosphorylation of the receptor as well as desensitization which is not due to an anpmediated decrease in the amount of receptor protein the mobility of gca on sodium dodecyl sulfatepolyacrylamide gel PACE increases T3 treatment of cells with anp and protein phosphatase a induces the same mobility shift the protein phosphatase also catalyzes dephosphorylation of gca and this is directly cof the parental line or the syncytiapositive clones longterm cultures revealed a marked delay in the appearance of reverse transcriptase rt activity in the supernatants of these subclones when compared with the parental L1 and viral replication did not lead to massive cell death syncytia formation in HIV+ cultures of the syncytiadeficient subclones was enhanced by TN factor alpha tnf alpha when added h postinfection in contrast i.c.v. with tnf alpha for h followed by washing and infection of the cells with hiv augmented syncytia formation of the syncytiapositive subclones but not of the syncytianegative subclones thus the emsmutagenized subclones may provide a tool to study host cell AF required for the establishment of a productive hiv infection and responsiveness to tnf alpha | MEDAL |
nonsteroidal antiinflammatory drugs have been a mainstay in the treatment of inflammatory diseases such as RA arthritis however these agents can result in severe and occasionally lifethreatening adverse effects that can limit therapeutic benefit progress toward safer antiinflammatory therapy was aided by the discovery that cyclooxygenase cox exists as two isozymes cox and cox both isozymes form prostaglandins that support physiologic functions however the formation of Th1 prostaglandins is catalyzed by cox inhibition of cox accounts for the antiinflammatory and analgesic action of nsaids however concurrent inhibition of cox inhibits prostaglandindependent mechanisms such as gastroduodenal mucosal defense and platelet aggregation this inhibition is the basis of the gastrointestinal toxicity and one characteristic of these drugs these findings led to the hypothesis that agents that selectively inhibit cox would possess antiinflammatory and analgesic action but would spare cox thereby avoiding adverse effects in the gastrointestinal tract and platelets selective cox inhibitors are now available the novelty of these agents has raised questions in the medical community as to what constitutes selectivity for cox this review outlines the criteria that must be met to characterize a compound as coxspecific clinical evidence of clear improvement in gastrointestinal tolerability and safety must be demonstrated in addition to cDNA evidence of cox selectivity obtained from enzyme PSA and clinical pharmacology evaluations | MEDAL |
