MDM2 chromosomes are cytogenetic manifestations of gene amplification frequently seen in CA cells genes amplified on double minute chromosomes include oncogenes and multidrug resistant genes these genes encode proteins which contribute to cancer formation CA progression and OD of resistance to drugs used in CA treatment beta of double minute chromosomes and therefore genes amplified on them is an effective way to decrease the malignancy of cancer cells we investigated the effectiveness of a CA drug gemcitabine on the loss of double minute chromosomes from the OC cell L1 uacc gemcitabine is able to decrease the number of double minute chromosomes in cells at a x lower concentration than the commonly used CA drug HU amplified genes present on the double minute chromosomes are decreased at the dna level upon gemcitabine treatment gemcitabine even at a low nanomolar concentration is able to cause dna damage the selective incorporation of double T2 chromatin and γhax signals into micronuclei provides a strong link between dna damage and the loss of double minute chromosomes from gemcitabine treated cells cells treated with gemcitabine also showed decreased cell growth colony formation and invasion together our results suggest that gemcitabine is ERP in decreasing double minute chromosomes and this affects the biology of OC cells

cholera enterotoxin inhibits the antigeninduced igemediated PR of histamine from human leukocytes and the lysis of allogeneic mastocytoma cells by splenic lymphocytes from specifically immunized mice this effect requires a prolonged preincubation time of the toxin with the lymphocyteleukocyte S9 a demonstrable inhibition requires about min of preincubation and the toxin activity is still increasing at min cholera enterotoxin also stimulates adenyl cyclase and leads to increased C2 of cyclic amp in the lymphocyteleukocyte S9 the concentration of toxin required for both cyclic amp accumulation and inhibition of the biologic responses is about the same ca ngml and the time course of cyclic amp accumulation parallels the development of LIA both activities inhibition of the in vitro HSRs and cAMP accumulation are blocked by cholera antitoxin and by a toxoid prepared from the toxin choleragenoid these are specific antagonists in that they do not block the inhibiting activity or rise in cyclic amp C2 caused by other cya stimulators because cholera enterotoxin has no known activity other than the stimulation of cya and because of its unusual time course and the availability of TPS antagonists this data considerably strengthens the hypothesis that the cAMP system influences the expression of these two forms of hypersensitivity phenomena

the objective of this T0 was to elucidate the antioxidative roles of coenzyme q coq and alphatocopherol in mitochondrial CM by determining whether coq directly scavenges peroxyl and alkoxylradicals or indirectly regenerates alphatocopherol during autooxidation of mitochondrial CM a comparison of the interaction between alphatocopherol and coq during autooxidation was made between bovine and rat heart mitochondria which differ approximately fold in their alphatocopherol content autooxidation of both bovine and rat HR mitochondria resulted in the formation of thiobarbituricacidreactive substances and protein carbonyls however the differences in the autooxidizability of mitochondria between rat and bovine heart mitochondrial membranes were relatively minor supplementation of rat HR mitochondria with succinate caused reduction of coq to ubiquinol while alphatocopherol concentration remained unaffected during autooxidation in contrast in the absence of succinate coq was present in the oxidized form ubiquinone and the mitochondrial membranes were depleted of alphatocopherol coq concentrations remained unchanged over time irrespective of the presence or absence of succinate in the absence of succinate autooxidation of bovine smps supplemented with different amounts of alphatocopherol was inversely related to the amount of alphatocopherol whereas in the presence of succinate autooxidation was greatly reduced results of this study indicate that during autooxidation of mitochondria alphatocopherol acts as the direct radical scavenger whereas ubiquinol reive in modulating basal binding at microm diamine than analogues which were mostly diprotonated or unprotonated finally the internuclear distance between the amino nitrogens and the extent of modulation of basal hmk binding were correlated similar but more modest effects were seen for spermineenhanced hmk IB these results are consistent with the existence of two polyamine IB sites associated with the nmda receptor complex one of the sites appears to preferentially recognize lipophilic substances while the other favors hydrophilic materials both sites appear to recognize PAs with at least one charged protonated amino group and one uncharged amino group the distance between amino CG is a determining factor as well

a healthy sodium depleted subject received on separate occasions intravenous infusions of the renin inhibitor h at doses of and mgkgh the two lower doses of h produced dosedependent reduction of both systolic and diastolic pressure associated with an increase in HR rate the highest dose of h produced profound SH and bradycardia both during drug infusion in the supine position and again later on return to standing after h was stopped an increase in plasma adrenaline but not noradrenaline was associated with this dose of h the subject differed from others studied in a randomised controlled trial of h at doses of and mgkgh in having the highest basal circulating plasma angiotensin ii concentrations during sodium depletion and in developing a clear reduction in systolic as well as Pd the profound hypotensive response at the highest dose of h may represent an idiosyncratic response to the drug alternatively and perhaps more likely it may be a result of a reduction of angiotensin ii concentrations in plasma or other tissues with loss of arteriolar constriction loss of facilitation of sympathetic activity withdrawal of vagal inhibition dilatation of capacitance vessels or a combination of these events subsequent activation of the bezoldjarisch reflex is a possibility the late fall in blood pressure T3 h was stopped and when circulating plasma angiotensin ii concentrations had returned to normal suggests that this response may have involved an effect of the inhibitor on renin in a site other than blood

femtosecond stimulated raman scattering fsrs is a spectroscopic technique that probes the structural dynamics of molecules the technique typically relies on an electronic resonance condition to increase signal strength or enhance species selectivity giving a raman enhancement that is vibrationalmodespecific and depends on the character of the resonant electronic state the resonance condition is complicated for molecules already in an excited electronic state and also for systems where multiple electronic states are resonant or nearly resonant with the raman excitation energy both of which are often the case for fsrs this paper examines the excitation wavelength dependence of the fsrs spectrum for the lowest triplet state of phenylthiophene pt except for an overall increase of the signal strength due to the resonance condition the relative intensities of most raman bands are relatively insensitive to the excitation wavelength and the spectrum is remarkably similar to the calculated offresonance spectrum obtained by neglecting the resonance condition on the other hand calculated resonance raman spectra using a gradient approximation to simulate the resonance condition correctly predict the excitation wavelength dependence for a few modes but overestimate the relative enhancement of others the weak wavelength dependence of the triplet spectrum of pt contrasts the case of the singlet fsrs spectrum for the same molecule we attribute this discrepancy to a combination of homogeneous broadening overlapping t

the adaptation of protein synthesis to environmental and physiological challenges is essential for cell viability here we show that translation is tightly linked to the proteinfolding environment of the cell through the functional properties of the ribosome bound chaperone nac nascent polypeptideassociated complex under nonstress conditions nac associates with ribosomes to promote translation and protein folding when proteostasis is imbalanced nac relocalizes from a ribosomeassociated state to protein aggregates in its role as a chaperone this results in a PET depletion of nac from the ribosome that diminishes translational capacity and the flux of nascent proteins SD of nac from polysomes and relocalisation to protein aggregates is observed during ageing in response to heat shock and upon expression of the highly aggregationprone polyglutamineexpansion proteins and aβpeptide these results demonstrate that nac has a central role as a proteostasis sensor to provide the cell with a regulatory FB mechanism in which translational activity is also controlled by the folding state of the cellular proteome and the cellular response to stress

the authors initial experience with awake videothoracoscopic lung resection suggests that these procedures can be easily and safely performed under sole thoracic epidural anesthesia with no mortality and negligible morbidity one L1 concern was that operating on a ventilating lung would render surgical maneuvers more difficult because of the lung movements and lack of a sufficient operating space instead the open PTX created after trocar insertion produces a satisfactory lung collapse that does not hamper surgical maneuvers these results contradict the accepted assumption that the main prerequisite for allowing successful thoracoscopic lung surgery is GA with onelung ventilation no particular training is necessary to accomplish an awake pulmonary resection for teams experienced in thoracoscopic surgery and conversions to general anesthesia are mainly caused by the presence of extensive fibrous pleural adhesions or the development of intractable panic attacks overall awake pulmonary resection is easily accepted and well tolerated by patients as confirmed by the high anesthesia satisfaction score which was better than in nonawake CP nonetheless thoracic EA has potential complications including EDH spinal cord injury and PN palsy caused by inadvertently high anesthetic level but these never occurred in the authors experience further concerns relate to patient participation in operating room conversations or risk for OD of perioperative PA however the authors have found that reassuring the patient during the procedure explaining stepbystep what is being performed and even showing the ongoing procedure on the operating video can greatly improve the perioperative wellness and expectations of patients particularly if the procedure is performed for oncologic diseases panic attacks occurred in few patients and could be usually managed through moderately increasing the depth of sedation while maintaining SB finally as long as the physiologic impact of awake metastasectomy is definitively elucidated the authors believe this modality should be used for unilateral procedures while deserving a staged bilateral approach for BL lung metastasectomy avoidance of GA results in a faster recovery with immediate return to many daily life activities including drinking eating and walking and a reduction in hospital stay and procedurerelated costs if confirmed with future studies these results could advocate earlier resection of peripheral solitary pulmonary nodules reducing the risk for delaying a diagnosis of unexpected pulmonary malignancy furthermore potential new frontiers of awake thoracoscopic surgery might include assessment of feasibility and safety of anatomic resections in properly selected instances ethical and economical concerns push remorselessly for less frequent and lessinvasive surgery administrators advocate minimal hospitalization and costsaving treatments whereas patients ultimately ask for appropriate health care thoracic surgeons of the third millennium must accept the challenge of this dynamic and rapidly evolving scenario without loosing the right root which probably lays just between wellestablished conventional surgery techniques and newly available advanced technology tools awake thoracic surgery will benefit from evidencebased data that are progressively accumulating findings will stimulate experts to continue an active clinical investigation in this unpredictably evolving surgical field which might ultimately lead to a better understanding of cardiorespiratory physiology and effects of the surgical pneumothorax and thoracic EPI anesthesia on perioperative respiratory CF in awake patients as the italian architect renzo piano recently stated recovering in the past can be reassuring but the future is the only place where we can go

preferential IB of an enzyme to the transition state relative to the ground state is a key strategy for enzyme catalysis when there is a difference between the ground and transition state charge distributions enzymes maximize electrostatic interactions to achieve this enhanced TS IB although the transition state is difficult to observe directly by structural methods the chemical details of this transient species can be characterized by studies of substituent effects brønsted hammett swainscott etc and isotope effects brønsted analysis can provide an estimate of TS charges for the nucleophile and leaving group of a reaction this account will discuss the theoretical basis of brønsted analysis and describe its practical application to the T0 of transacylase enzyme systems including the peptidyl GOT reaction of the ribosome the brønsted coefficient is derived from the linear free SE relationship lfer that correlates the acidity pka of a reactive atom to the log of its rate constant the brønsted coefficient establishes the change in atomic charge as the reaction proceeds from the ground state to the TS bonding events alter the electrostatics of atoms and the extent of bonding can be extrapolated from transition state charges therefore welldefined nucleophile and leaving group transition state charges limit the number of mechanisms that are consistent with a particular TS brønsted results are most informative when interpreted in the context of other mechanistic data especially for enzymatic studies where an active site may promote a transition state that differs significantly from a prediction based on uncatalyzed solution reactions here we review brønsted analyses performed on transacylases to illustrate how these data enhanced the enzymatic mechanistic studies through a systematic comparison of five enzymes we reveal a wide spectrum of brønsted values that are possible for what otherwise appear to be similar chemical reactions the variations in the brønsted coefficients predict different transition states for the various enzymes this account explores an overriding theme in the enzymatic mechanisms that catalysis enhances commensurate bond formation and proton abstraction events the extent of the two bonding events in relationship to each other can be inferred from the brønsted coefficient when viewed in the context of recent ribosomal studies this interpretation provides mechanistic insights into peptide bond formation
