Smoking cessation programs started as late as 4 weeks before surgery reduce perioperative morbidity and death, yet outpatient clinic interventions are rarely provided. Our aim was to evaluate the feasibility of implementing a tobacco treatment protocol designed for an outpatient surgical setting.<br />We completed a pre-post feasibility study of the implementation of a systematic, evidence-based tobacco treatment protocol in an outpatient colorectal surgery clinic. Outcomes included smoking prevalence, pre- and postimplementation smoker identification and intervention rates, recruitment, retention, smoking cessation and provider satisfaction.<br />Preimplementation, 15.5% of 116 surveyed patients were smokers. Fewer than 10% of surveyed patients reported being asked about smoking, and none were offered any cessation intervention. Over a 16-month postimplementation period, 1198 patients were seen on 2103 visits. Of these, 950 (79.3%) patients were asked smoking status on first visit and 1030 (86.0%) were asked on eduction and cessation.<br />Rubella virus has pronounced teratogenic properties that can cause generalized and persistent intrauterine infection of the fetus. As a result, the control of the loss of teratogenicity inherent in «wild-type» virus strains is a necessary stage of a preclinical study of the vaccine strain for a live attenuated rubella vaccine.The purpose of the study is to comprehensively study the teratogenic properties of the vaccine strain of rubella virus «Orlov-V» in the experiment on rhesus macaques.<br />Seronegative to rubella virus female rhesus macaques in early pregnancy at the age of 4-7 years (n = 13) were used in the experiment. Animals of the experimental group (n = 9) received single immunization intramuscularly with a preparation from the «Orlov-V» strain. The control group of the monkeys (n = 3) were immunized with a commercial vaccine containing Wistar RA27/3 strain. The female of the control group (n = 1) was injected with a solvent used in the rubella vaccine. Study of possible teratogenic properties of vaassessment of specific safety of antiviral vaccines including a complex of clinical, immunological, pathologic and virological methods instead of the classical pathologic method is discussed.<br />The results obtained in this study showed the absence of teratogenic properties and high immunogenic activity of the vaccine strain of rubella virus «Orlov-V».<br />The results obtained in this study showed the absence of teratogenic properties and high immunogenic activity of the vaccine strain of rubella virus «Orlov-V».Lysine-specific demethylase 1 (LSD1/KDM1A) oxidatively removes methyl groups from histone proteins, and its aberrant activity has been correlated with cancers including acute myeloid leukemia (AML). We report a novel series of tranylcypromine analogues with a carboxamide at the 4-position of the aryl ring. These compounds, such as 5 a and 5 b with benzyl and phenethylamide substituents, respectively, had potent sub-micromolar IC50 values for the inhibition of LSD1 as well as cell proliferation in a panel of AML cell lines. The dose-dependent increase in cellular expression levels of H3K4me2, CD86, CD11b and CD14 supported a mechanism involving LSD1 inhibition. The tert-butyl and ethyl carbamate derivatives of these tranylcypromines, although inactive in LSD1 inhibition, were of similar potency in cell-based assays with a more rapid onset of action. This suggests that carbamates can act as metabolically labile tranylcypromine prodrugs with superior pharmacokinetics.<br />To study the role of exosomes in the protective effect of cerebral ischemic preconditioning (cerebral-IPC) against cerebral I/R injury.<br />Mouse models of cerebral-IPC and MCAO/R were established as described previously, and their behavioral, pathological, and proteomic changes were analyzed. Neuro-2a subjected to OGD/R were treated with exosomes isolated from the plasma of sham-operated and cerebral-IPC mice. The differentially expressed miRNAs between exosomes derived from sham-operated (S-exosomes) and preconditioned (IPC-exosomes) mice were identified through miRNA array, and their targets were identified through database search. The control and OGD/R cells were treated with the IPC-exosomes, miRNA mimic or target protein inhibitor, and their viability, oxidative, stress and apoptosis rates were measured. The activated pathways were identified by analyzing the levels of relevant proteins.<br />Cerebral-IPC mitigated the cerebral injury following ischemia and reperfusion, and increased the number of plasma exosomes. IPC-exosomes increased the survival of Neuro-2a cells after OGD/R. The miR-451a targeting Rac1 was upregulated in the IPC-exosomes relative to S-exosomes. The miR-451a mimic and the Rac1 inhibitor NSC23766 reversed OGD/R-mediated activation of Rac1 and its downstream pathways.<br />Cerebral-IPC ameliorated cerebral I/R injury by inducing the release of exosomes containing miR-451a.<br />Cerebral-IPC ameliorated cerebral I/R injury by inducing the release of exosomes containing miR-451a.Whole-cell bioconversion of technical lignins using Pseudomonas putida strains overexpressing amine transaminases (ATAs) has the potential to become an eco-efficient route to produce phenolic amines. Here, a novel cell growth-based screening method to evaluate the in vivo activity of recombinant ATAs towards vanillylamine in P. putida KT2440 was developed. It allowed the identification of the native enzyme Pp-SpuC-II and ATA from Chromobacterium violaceum (Cv-ATA) as highly active towards vanillylamine in vivo. Overexpression of Pp-SpuC-II and Cv-ATA in the strain GN442ΔPP_2426, previously engineered for reduced vanillin assimilation, resulted in 94- and 92-fold increased specific transaminase activity, respectively. Whole-cell bioconversion of vanillin yielded 0.70 ± 0.20 mM and 0.92 ± 0.30 mM vanillylamine, for Pp-SpuC-II and Cv-ATA, respectively. [https://www.selleckchem.com/products/S31-201.html NSC 74859 ic50] Still, amine production was limited by a substantial re-assimilation of the product and formation of the by-products vanillic acid and vanillyl alcohol. Concomitant overexpression of Cv-ATA and alanine dehydrogenase from Bacillus subtilis increased the production of vanillylamine with ammonium as the only nitrogen source and a reduction in the amount of amine product re-assimilation. Identification and deletion of additional native genes encoding oxidoreductases acting on vanillin are crucial engineering targets for further improvement.
