cortical bone is perforated by a network of canals that have a significant impact upon its material properties microcomputed tomography offers the possibility of noninvasively visualizing and quantifying cortical pores in both two and three dimensions establishing how 2DE d microcomputed tomographic microct analysis compares with conventional methods for analyzing cortical porosity is an important prerequisite for the wider adoption of this technique and the OD of threedimensional d analysis therefore we compared porosityrelated parameters from d microcomputed tomographic images with those from matching microradiographic sections samples from five human femora were scanned at a microm resolution and then sequentially sectioned and microradiographed an average of eight image pairs were produced from each femur total n the repeatability and comparability of the two techniques was assessed for three parameters cortical porosity mean pore area microm and pore density poresmm for repeatability no significant difference p was found between the two methods for cortical porosity and mean pore area however pore density differed significantly p for comparability the bias error between the methods was found to be for cortical porosity and microm microm for mean pore area the bias for pore density was dependent upon measurement size with microcomputed tomographic images having fewer pores per millimeter squared the qualitative and quantitative similarities between the two techniques demonstrated the utility of d microcomputed tomographic for cortical porosity analysis however the relatively poor results for pore density revealed that a higher resolution microm is needed to consistently visualize all cortical pores in human bone

biosynthesis of the mo cofactor moco can be divided into the formation of a F0 and the latters subsequent conversion by molybdopterin synthase into the organic moiety of moco these two steps are reflected by the complementation CG a and b and the two formally distinguished types of moco deficiency that have an MZ phenotype both types of moco deficiency result in a pleiotropic loss of all molybdoenzyme activities and cause severe neurological damage mocs is defective in patients with group a deficiency and has been shown to encode two enzymes for early synthesis via a bicistronic transcript with two consecutive open reading frames orfs mocs encodes the small and large subunits of MPT synthase via a single transcript with two overlapping reading frames this gene was mapped to q and comprises seven exons the coding CS and all splice sitejunction sequences were screened for mutations in mocodeficient patients in whom a previous search for mocs mutations had been negative in seven of the eight patients whom we investigated we identified mocs mutations that by their nature are most likely responsible for the deficiency three different frameshift mutations were observed with one of them found on of identified alleles furthermore a startcodon mutation and a missense mutation of a highly conserved amino acid residue were found the locations of the mutations confirm the PET role of both orfs one of the patients with identified mocs mutations had been classified as type b in complementation studies these findings support the hypothetical mechanism for both forms of moco deficiency that formerly had been established by cellculture experiments

HG and diabetes are associated with ECD arising from enhanced oxidative injury leading to the progression of diabetic V1 pathologies the redoxsensitive transcription factor nuclear factorerelated factor nrf is a master regulator of antioxidant genes such as heme oxygenase ho involved in cellular defenses against oxidative AS we have investigated the pathways involved in high glucoseinduced activation of ho in endothelial cells and examined the molecular mechanisms underlying cytoprotection elevated dglucose increased intracellular generation of reactive oxygen species ros leading to nuclear translocation of nrf and ho expression in BAE cells with no changes in cell viability superoxide scavenging and inhibition of eNOS synthase enos abrogated upregulation of ho expression by elevated gl inhibition of ho increased the sensitivity of endothelial cells to high glucosemediated damage while addition of bilirubin restored cell viability our findings establish that exposure of endothelial cells to HG leads to activation of endogenous antioxidant defense genes via the nrfare pathway upregulation of ho provides cytoprotection against high glucoseinduced oxidative stress through the antioxidant properties of bilirubin modulation of the nrf pathway in the early stages of diabetes may thus protect against sustained damage by hyperglycemia during progression of the disease

the microviscosity of cellular CM or membrane fluidity was measured in suspensions of single mucosal cells isolated from the UB of the toad bufo marinus by the technique of polarized fluorescence emission specthat the measured MICs were significantly increased above those of the controls the highest activity was found in the microsomal and lysosomal fractions in the absence of mg during incubation the difference in phosphohydrolase MICs between eu and hyperthyroid states was not significant the phosphohydrolase of subcellular fractions of control hamsters did not respond to addition of mmmg the enzyme from CM NF was slightly inhibited by this bivalent cation and therefore significant increases in activity were observed only in the absence of mg from the CA system the rate of reaction by soluble phosphatidate phosphohydrolase was similar regardless of the nature of the substrate both when microsomalbound phosphatidate was used as the substrate and when phosphatidate suspension was used the activity of soluble enzyme was lower than that of the microsomal and lysosomal enzymes measured with PA suspension this was especially so when the CA was carried out in the absence of mg neither triiodothyronine nor cardiomyopathy influenced the soluble phosphohydrolase activity in the two species neither triiodothyronine nor cardiomyopathy significantly changed palmitoylcoa hydrolase activities in subcellular fractions microsomal diacylglycerol acyltransferase and myocardial triacylglycerol content were also unchanged in the hyperthyroid state

henochschonlein purpura is a clinical syndrome characterized by the association of skin joint and gastrointestinal PS henochschonlein purpura is characterized by widespread vasculitis although the clinical PS of this disease are characteristic the diagnosis is not always easy to establish because other forms of systemic vasculitis mainly the microscopic form of periarteritis nodosa may mimic the disease in addition in contrast to SVR LE there are no biological tests that can identify henochschonlein purpura with certainty immunofluorescence microscopic techniques have made an important contribution to both the diagnosis and the T0 of the pathogenesis of the disease particularly since they have demonstrated the presence of iga deposits in the glomeruli and in the vessel walls these findings not only confirmed the immunologic nature of the pathologic lesions but also drew attention to the remarkable similarity between HSP nephritis and iga nephropathy

nodulation factor nf ST in the legumerhizobium symbiosis involves calcium oscillations that are instrumental in eliciting nodulation to date ca spiking has been studied exclusively in the intracellular bacterial invasion of growing root hairs in zone i this mechanism is not the only one by which rhizobia gain entry into their hosts the tropical legume sesbania rostrata can be invaded intercellularly by rhizobia at cracks caused by lateral root emergence and this process is associated with cell death for formation of infection pockets we show that epidermal cells at lateral root bases respond to nfs with ca oscillations that are faster and more symmetrical than those observed during root hair invasion enhanced jasmonic acid or reduced DDE levels slowed down the ca spiking frequency and stimulated intracellular root hair invasion by rhizobia but prevented nodule formation hence intracellular invasion in root hairs is linked with a very TPS ca signature in parallel experiments we found that knockdown of the calciumcalmodulindependent protein kinase gene of s rostrata abolished nodule development but not the formation of infection pockets by intercellular invasion at lateral root bases suggesting that the colonization of the outer cortex is independent of ca spiking decoding

the use of neurobehavioral techniques in toxicology has increased dramatically over the past several years several national and international CG have recommended that neurobehavioral tests be included in the initial stages of hazard ID and RII agencies have responded by preparing testing guidelines or requiring behavioral tests data for premarket approval of environmental and pharmaceutical chemicals in addition neurobehavioral data have been used to set SE limits in the workplace in the future neurobehavioral data will be used more frequently in the area of risk assessment which has been defined as the characterization of the potential adverse effects of human SE to environmental hazards national academy of sciences good risk assessment depends on the ability to determine whether a particular agent is or is not causally linked to a particular health effect and on the availability of DR data for quantitative risk assessment neurobehavioral techniques used in animal behavioral toxicology measure neurobiological functions similar to those measured in humans in addition neurobehavioral procedures can be used in longitudinal studies where the onset and duration of effects of chemical SE can be measured in the same animal neurobehavioral techniques are also amenable to the T0 of tolerance and compensation following repeated SE or following REC of function that can occur following cessation of SE therefore neurobehavioral procedures provide a valuable tool for research designed to reduce major uncertainties associated with the risk assessment process such as animal to human extrapolation homology of animal models and dosing issues ie hightolow dose acute vs repeated dosing and continuous vs episodic dosing although the use of neurobehavioral procedures has had a significant impact on neurotoxicology their use in the risk assessment process and in monitoring populations for possible subtle changes in neurobiological CF will be limited if additional research is not done to understand the neural substrates underlying neurobehavioral endpoints the ability to link chemically induced behavioral changes to alterations at the neurophysiological neurochemical and neuroanatomical C2 will lead to a greater acceptance of the validity and reliability of neurobehavioral endpoints in defining adverse effects of chemicals on the nervous system
