Nickel(II) metal-organic framework (Ni-MOF) was used as an efficient catalyst for the synthesis of 2-aryl benzimidazole and benzothiazole derivatives. Stenoparib in vivo Ni-MOF was prepared using nickel(II) nitrate hexahydrate and 4,4'- diaminodiphenyl sulfone (DDS), then characterized via XRD, FE-SEM, EDX, FT-IR, BET, and TGA/DTG. The catalyst was then used in the synthesis of some benzimidazole and benzothiazole derivatives. It was found to be an efficient method for the preparation of 2-aryl benzimidazole and benzothiazole derivatives in good to excellent yields at room temperature. The catalyst was easily recovered and reused five times without substantial loss in activity. This procedure has further advantages including mild and environmentally benign conditions, easy workup, simple procedure, high yields, recyclability and nontoxicity of the catalyst.

The NSZ was used as an excellent solid acid catalyst for one-pot, three-component synthesis of 2-aryl-N-benzimidazole-4-thiazolidinones via condensation of 2-aminobenzimidazole, aromatic aldehydes and thioglycolic acid, in H2O-acetone at room temperature. Then, zeolo sulfuric acid was applied for the synthesis of tri-substituted imidazole derivatives via the one-pot and solvent-free cyclo-condensation of different aldehydes, benzil and ammonium acetate. This efficient catalytic approach offers several advantages, such as excellent yields and high purity, inexpensive procedure and ease of product isolation, the use of nontoxic and heterogeneous acid catalyst, shorter reaction times and milder conditions.

In this study, we investigated the relationship using viremia copy-years (VCY), a cumulative measure of HIV plasma viral burden. METHODS Data were analyzed for 686 PLWH in the Florida Cohort Study who had at least five years of VL data before the baseline. VL data were extracted from Enhanced HIV/AIDS Reporting System (eHARS) and used to define peak VL (pVL), recent VL (rVL), and undetectable VL (uVL rVL5.7) for analysis. Hypertension was determined based on hypertension diagnosis from medical records. Multivariable logistic regression was used for association analysis. RESULTS Of the total sample, 277 (40.4%) participants were hypertensive. Compared to the participants with lowest VCY ( less then 2.7 log10 copy × years/mL), the odds ratios (OR) and 95% confidence interval [95% CI] for hypertension of the remaining four groups, in order, were 1.91 [1.11, 3.29], 1.91 [1.03, 3.53], 2.27 [1.29, 3.99], and 1.25 [0.65, 2.42], respectively, controlling for confounders. The association was independent of pVL, rVL, and uVL, each of which was not statistically significant associations with hypertension. CONCLUSION Persistent HIV infection is a risk factor for hypertension among PLWH. Information provided by VCY is more effective than single time-point VL measures in investigating HIV infection-hypertension relationship. Findings of this study support the significance of continuous viral suppression in hypertension prevention among PLWH.

Microglia contributes to the earliest responses to Aβ buildup, by direct interaction through multiple receptors. Microglial cells operate Aβ clearance and trigger inflammatory/regenerative processes that take place in the long years of silent disease progression that precede symptomatic appearance. But in time and with aging, the fine balance between pro- and anti-inflammatory activity of microglia deranges, negatively impacting its Aβ-clearing ability. Furthermore, in recent years, microglial activation has proven to be much more complex than the mere dichotomic pro/anti-inflammatory polarization previously accepted. Microglia can display a wide spectrum of phenotypes, which can even be mixed. On these basis, it appears evident that while pharmacological intervention aiding microglia to prolong its ability to cope with Aβ buildup could be extremely relevant, its feasibility is hampered by such high complexity which still needs to be completely understood.

OBJECTIVE This exploratory study aims to determine (1) whether neurocognitive impulsivity dimensions and externalizing/internalizing traits are correlated between siblings discordant for heroin and amphetamine dependence; and (2) which of these associations are common across substances and which are substance-specific. METHODS Pearson correlations between individuals with 'pure' heroin and amphetamine dependence and their unaffected biological siblings (n = 37 heroin sibling pairs; n = 30 amphetamine sibling pairs) were run on 10 neurocognitive measures, 6 externalizing measures, and 5 internalizing measures. Sibling pair effects were further examined using regression. RESULTS Siblings discordant for heroin dependence were significantly correlated on delay aversion on the Cambridge Gambling Task, risk-taking on the Balloon Analht© Bentham Science Publishers; For any queries, please email at [email protected] Neuroserpin is a serine protease inhibitor predominantly expressed in the nervous system functioning mainly in neuronal migration and axonal growth. Neuroprotective effects of neuroserpin was shown in animal models of stroke, brain and spinal cord injury. Postmortem studies confirmed the involvement of neuroserpin in Alzheimer's disease. Since altered adult neurogenesis was postulated as an aetiological mechanism for bipolar disorder, the possible effect of neuroserpin gene expression in the disorder has been evaluated. METHODS Neuroserpin mRNA expression levels were examined in the peripheral blood of bipolar disorder type I manic and euthymic patients and healthy controls using the polymerase chain reaction method. The sample comprised of 60 physically healthy, middle-aged men as participants whom had no substance use disorder. RESULTS The gene expression levels of neuroserpin were found lower in the bipolar disorder patients than the healthy controls (p=0.000). The neuroserpin levels did not differ between mania and euthymia (both 96% down-regulated compared to the controls). CONCLUSION Since we detected difference between the patients and the controls, not the disease states, the dysregulation in the neuroserpin gene could be interpreted as a result of the disease itself.

The canonical roles of telomerase are at the telomere ends where they elongate telomeres and maintain genomic stability and cellular lifespan. The catalytic protein component telomerase reverse transcriptase (TERT) is preferentially expressed at high levels in cancer cells despite the existence of an alternative mechanism for telomere maintenance (alternative lengthening of telomeres or ALT). TERT is also expressed at higher levels than necessary for maintaining functional telomere length, suggesting other possible adaptive functions. Emerging non-canonical roles of TERT include regulation of non-telomeric DNA damage responses, promotion of cell growth and proliferation, acceleration of cell cycle kinetics, and control of mitochondrial integrity following oxidative stress. Non-canonical activities of TERT primarily show cellu.net.BACKGROUND A research on mood disorder pathophysiology has hypothesized abnormalities in glutamatergic neurotransmission, by suggesting further investigation on glutamatergic N-methyl-Daspartate (NMDA) receptor modulators in treating Major Depressive Disorder (MDD). Esketamine (ESK), an NMDA receptor antagonist able to modulate glutamatergic neurotransmission has been recently developed as an intranasal formulation for treatment-resistant depression (TRD) and for rapid reduction of depressive symptomatology, including suicidal ideation in MDD patients at imminent risk for suicide. OBJECTIVE The present study aims at investigating recent clinical findings on research on the role of the glutamatergic system and ESK in treating suicidal depression in MDD and TRD. METHODS A systematic review was here carried out on PubMed/Medline, Scopus and the database on U.S. N.I.H. Clinical Trials (https//clinicaltrials.gov) and the European Medical Agency (EMA) (https//clinicaltrialsregister.eu) from inception until October 2019. RESULTS Intravenous infusion of ESK is reported to elicit rapid-acting and sustained antidepressant activity in refractory patients with MDD and TRD. In phase II studies, intranasal ESK demonstrated a rapid onset and a persistent efficacy in patients with TRD as well as in MDD patients at imminent risk for suicide. However, some data discrepancies have emerged in phase III studies. CONCLUSION The U.S. Food and Drug Administration (FDA) granted fast track and Breakthrough Therapy Designation to Janssen Pharmaceuticals®, Inc. for intranasal ESK in 2013 for treatment-resistant depression (TRD) and in 2016 for the treatment of MDD with an imminent risk of suicide. However, further studies should be implemented to investigate the long-term efficacy and safety of intranasal ESK.

Furthermore, the diagnostic tools in use not only stray away from the conventional medical framework, but also remain invalidated with evidence-based concepts. However, neuroscience as a source of valid objective knowledge has initiated the process of a paradigm shift underlined by the main concept of psychiatric disorders being "brain disorders". It is also a bridge closing the explanatory gap among the different fields of medicine via the translation of knowledge within a multi-disciplinary framework. The contemporary neuroimaging methods such as fMRI provide researchers with an entirely new set of tools to reform the current status quo by creating an opportunity to define and validate objective biomarkers that can be translated into clinical practice. Combining multiple neuroimaging techniques with the knowledge of the role of genetic factors, neurochemical imbalance and neuroinflammatory processes in the etiopathophysiology of psychiatric disorders is a step towards a comprehensive biological explanation of psychiatric disorders and a final differentiation of psychiatry as a well-founded medical science. In addition the neuroscientific knowledge gained thus far suggests a necessity for directional change to exploring multidisciplinary concepts such as multiple causality and dimensionality of psychiatric symptoms and disorders. A concomitant viewpoint transition of the notion of validity in psychiatry with a focus on an integrative validatory approach may facilitate the building of a collaborative bridge above the wall existing between the scientific fields analyzing the mind and those studying the brain.
