Combined Linkage and Association Analyses of the 124-bp Allele of Marker D2S2944 with Anxiety, Depression, Neuroticism and Major Depression

A central issue in psychiatric genetics is whether positive findings replicate. Zubenko et al. (2002b, Mol. Psychiatry 7:460-467) reported an association of the 124-bp allele of D2S2944 with recurrent early-onset major depression for females. We tested for association of this allele to continuous measures of anxiety, depression and neuroticism in a Dutch sample of 347 males and 448 females, and to DSM-IV major depression in a subsample of 210 males and 295 females. The association of the 124-bp allele to depression in females was not replicated, but there were significant associations (not significant after correction for multiple testing) with anxiety and anxious depression in males. However, the association occurred in the absence of evidence for linkage in this region on chromosome 2. © 2006 Springer Science+Business Media, Inc

Development and research of the stamp for cutting of a rolled stock with a differentiated clamp

The work aims to develop and research a stamp with a differentiated clamp of a rolled stock for cutting by shear. A new stamp design with a differentiated clamp of the rolled stock has been developed. In terms of their technical and economic indicators, these stamps meet or exceed the modern samples of similar punch tools. At the same time, in the process of vertical cutting, a constant position of the rolled stock axis is ensured. The transmission of force to the clamp through the rolled stock is excluded. The stamp design ensures its sufficiently high rigidity and relatively small overall dimensions. Based on the analysis of the mathematical model of a stamp with a differentiated clamp, the effective angles of force transmission to the clamp and the cutting of the rolled stock between the stamp parts have been established. The resulting model was used to optimize the angles of force transfer to the clamp, and the cutting rolled stock, respecting the force from the side of a buffer and the minimum required press force. At the same time, the vertical stroke of the moving parts is reduced, the overall dimensions of the stamp are decreased, and the buffer also has a minimum size. To reduce the required force of the press, it is necessary to reduce the value of a frictional slipping coefficient by using antifriction materials on contact surfaces and ensuring good lubrication conditions. The results of the conducted experiments confirm the adequacy of the mathematical model. The value of the required force on the press slide available from experiments is slightly higher than the values obtained by the developed analytical model. The results of the stamp implementation show that: the stamps are efficient and reliable in exploitation; the quality of the cutoff workpieces corresponds to the quality indicators of the workpieces cut on similar modern equipment

Analysis of SEC9 Suppression Reveals a Relationship of SNARE Function to Cell Physiology

BACKGROUND:Growth and division of Saccharomyces cerevisiae is dependent on the action of SNARE proteins that are required for membrane fusion. SNAREs are regulated, through a poorly understood mechanism, to ensure membrane fusion at the correct time and place within a cell. Although fusion of secretory vesicles with the plasma membrane is important for yeast cell growth, the relationship between exocytic SNAREs and cell physiology has not been established. METHODOLOGY/PRINCIPAL FINDINGS:Using genetic analysis, we identified several influences on the function of exocytic SNAREs. Genetic disruption of the V-ATPase, but not vacuolar proteolysis, can suppress two different temperature-sensitive mutations in SEC9. Suppression is unlikely due to increased SNARE complex formation because increasing SNARE complex formation, through overexpression of SRO7, does not result in suppression. We also observed suppression of sec9 mutations by growth on alkaline media or on a non-fermentable carbon source, conditions associated with a reduced growth rate of wild-type cells and decreased SNARE complex formation. CONCLUSIONS/SIGNIFICANCE:Three main conclusions arise from our results. First, there is a genetic interaction between SEC9 and the V-ATPase, although it is unlikely that this interaction has functional significance with respect to membrane fusion or SNAREs. Second, Sro7p acts to promote SNARE complex formation. Finally, Sec9p function and SNARE complex formation are tightly coupled to the physiological state of the cell

ТРАНСПЛАНТАЦИЯ ПЕЧЕНИ ОТ ДОНОРОВ СТАРШЕ 60 ЛЕТ

Donor organs shortage leads to extending criteria for deceased liver donation in the whole world.Aim: to compare results of deceased donor liver transplantation (DDLT) depending of donor age over 60 years old.Materials and methods: the study includes 390 DDLT from January 2010 to November 2017. All liver donors separated by age for two groups: I – 60 years and older (n = 26); II – younger than 60 years (n = 364). All donors were standardized by demographic, laboratory fi ndings and inotropic drug requirement. Results: no difference between both groups in severity of ischemia-reperfusion injury, ICU or in-hospital staying (median 2 and 7,5 days respectively) was found. There is also no difference between biliary or vascular complication rate. 5-year actuarial survival rate found no difference between both groups (I: 70%: II: 76%, p = 0,54).Conclusion. Using grafts from donors older than 60 years don’t worsen early and late results of DDLT. Care should be taken to avoid other risk factors (cold ischemia time, warm ischemia time).Дефицит донорских органов во всем мире способствует постепенному расширению донорских критериев для трансплантации.Цель: провести анализ результатов трансплантации печени от доноров 60 лет и старше в сравнении с донорами более молодого возраста.Материалы и методы: в исследование включено 390 трансплантаций печени: группа I – возраст донора 60 и более лет (n = 26); группа II – возраст донора менее 60 лет (n = 364), выполненных за период с 2010-го по ноябрь 2017 г. Доноры обеих групп стандартизованы по демографическим характеристикам, лабораторным показателям, а также объему инотропной поддержки.Результаты: статистически значимых различий тяжести ишемически-реперфузионного повреждения трансплантата, длительности пребывания в отделении реанимации, продолжительности пребывания в стационаре не выявлено.Также не выявлено различий в частоте развития билиарных или сосудистых осложнений. Сравнение 5-летней актуриальной выживаемости не показало достоверной разницы (группа I – 70%; группа II – 76%, р = 0,54).Выводы. По нашему опыту, использование трансплантатов печени от доноров старше 60 лет при условии минимизации факторов риска (холодовая ишемия, вторичная тепловая ишемия) не ухудшает результаты трансплантации печени в раннем и отдаленном сроке и может быть одним из путей увеличения числа трансплантаций печени от посмертного донора. Длительность наблюдения за реципиентами 8 лет

Genetic Linkage and Association Analysis for Loneliness in Dutch Twin and Sibling Pairs Points to a Region on Chromosome 12q23–24

We obtained evidence from a large study in Dutch twins (N = 8387) and siblings (N = 2295) that variation in loneliness has a genetic component. The heritability estimate for loneliness, which was assessed as an ordinal trait, was 40% and did not differ between males and females. There were 682 sibling pairs with genotypic (around 400 microsatellite markers) data. We combined phenotypic and genotypic data to carry out a genome scan to localize QTLs for loneliness. One region on chromosome 12q23.3-24.3, showed near suggestive linkage. Genetic association tests within this region revealed significant association (p-value 0.009) with one of the alleles of marker D12S79 and with one of the alleles of neighbouring marker D12S395 (p-value 0.043). We review evidence for linkage in this region for psychiatric disorders and discuss our findings within this context. © 2006 Springer Science+Business Media, Inc

Трансплантация печени от посмертного донора 73 лет

Orthotopic liver transplantation is the only way to cure chronic liver failure and certain liver tumors. Deceased donor organs are the prevailing source in most transplantation centers. However, there is an organ shortage because of the increasing number of patients in need of transplantation. Using expanded criteria deceased donors is a routine way to overcome organ shortage. The majority of transplantation centers take older donors depending on the local rules. Successful liver transplantation from 73-year-old deceased donor. Recipient suffered from liver neuroendocrine tumor without signs of extrahepatic spread. Liver function is adequate during 90-day follow-up. Liver transplantation from older deceased donors has good outcome according to world experience. Careful donor-recipient selection is the key to success. The first positive trial in our center enlightens the way for further practice.Расширение критериев изъятия печени при трансплантации от доноров со смертью мозга представляет собой наиболее распространенную практику преодоления дефицита органов для трансплантации. В зависимости от принятых правил большинство центров трансплантации не считают возраст противопоказанием к донорству органов при прочих удовлетворительных параметрах, а правильный подбор пары «донор–реципиент» позволяет получить удовлетворительный результат. Приводится клиническое наблюдение трансплантации печени от донора 73 лет реципиенту с метастазами нейроэндокринной опухоли в печень. Функция трансплантата удовлетворительная в течение 3 месяцев на момент публикации. Положительный исход, обзор опыта большого количества центров трансплантации печени позволяют надеяться на дальнейшее расширение подобной практики

Transcriptional Evidence for the Role of Chronic Venlafaxine Treatment in Neurotrophic Signaling and Neuroplasticity Including also Glutatmatergic- and Insulin-Mediated Neuronal Processes.

OBJECTIVES: Venlafaxine (VLX), a serotonine-noradrenaline reuptake inhibitor, is one of the most commonly used antidepressant drugs in clinical practice for the treatment of major depressive disorder (MDD). Despite being more potent than its predecessors, similarly to them, the therapeutical effect of VLX is visible only 3-4 weeks after the beginning of treatment. Furthermore, recent papers show that antidepressants, including also VLX, enhance the motor recovery after stroke even in non depressed persons. In the present, transcriptomic-based study we looked for changes in gene expressions after a long-term VLX administration. METHODS: Osmotic minipumps were implanted subcutaneously into Dark Agouti rats providing a continuous (40 mg/kg/day) VLX delivery for three weeks. Frontal regions of the cerebral cortex were isolated and analyzed using Illumina bead arrays to detect genes showing significant chances in expression. Gene set enrichment analysis was performed to identify specific regulatory networks significantly affected by long term VLX treatment. RESULTS: Chronic VLX administration may have an effect on neurotransmitter release via the regulation of genes involved in vesicular exocytosis and receptor endocytosis (such as Kif proteins, Myo5a, Sv2b, Syn2 or Synj2). Simultaneously, VLX activated the expression of genes involved in neurotrophic signaling (Ntrk2, Ntrk3), glutamatergic transmission (Gria3, Grin2b and Grin2a), neuroplasticity (Camk2g/b, Cd47), synaptogenesis (Epha5a, Gad2) and cognitive processes (Clstn2). Interestingly, VLX increased the expression of genes involved in mitochondrial antioxidant activity (Bcl2 and Prdx1). Additionally, VLX administration also modulated genes related to insulin signaling pathway (Negr1, Ppp3r1, Slc2a4 and Enpp1), a mechanism that has recently been linked to neuroprotection, learning and memory. CONCLUSIONS: Our results strongly suggest that chronic VLX treatment improves functional reorganization and brain plasticity by influencing gene expression in regulatory networks of motor cortical areas. These results are consonant with the synaptic (network) hypothesis of depression and antidepressant-induced motor recovery after stroke
