More importantly, B3C might offer disease-modifying potentials by activating myocyte enhancer factor 2D transcription, inducing neuritogenesis, and promoting the expressions of neurotrophic factors in vitro and in vivo. Taken together, the novel dimers might offer synergistic disease-modifying effects, proving that dimerization might serve as one of the strategies to develop new generation of therapeutics for neurodegenerative disorders.Host cell proteins (HCPs) are process-related impurities that may copurify with biopharmaceutical drug products. Within this class of impurities there are some that are more problematic. These problematic HCPs can be considered high-risk and can include those that are immunogenic, biologically active, or enzymatically active with the potential to degrade either product molecules or excipients used in formulation. Some have been shown to be difficult to remove by purification. Why should the biopharmaceutical industry worry about these high-risk HCPs? What approach could be taken to understand the origin of its copurification and address these high-risk HCPs? To answer these questions, the BioPhorum Development Group HCP Workstream initiated a collaboration among its 26-company team with the goal of industry alignment around high-risk HCPs. The information gathered through literature searches, company experiences, and surveys were used to compile a list of frequently seen problematic/high-risk HCPs. These high-risk HCPs were further classified based on their potential impact into different risk categories. A step-by-step recommendation is provided for establishing a comprehensive control strategy based on risk assessments for monitoring and/or eliminating the known impurity from the process that would be beneficial to the biopharmaceutical industry.An outbreak of a novel coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had emerged in 2019 and rapidly posed a global epidemic. Here, we report the breadth of concomitant virological features of a family cluster with COVID-19. The period of virus shedding is significantly different between upper respiratory and feces samples. Even the SARS-CoV-2 virus titers were undetectable in feces, it could be positive again soon and likely related to fluctuated inflammation levels (interleukin-6, etc.) and lowered immune responses (CD4 + T lymphocyte, etc.). Our findings expand the novel understanding of the breadth of concomitant virological features during a non-severe family cluster of COVID-19.AlkB homolog 1 (ALKBH1) is responsible for the biogenesis of 5-formylcytidine (f5 C) on mitochondrial tRNAMet and essential for mitochondrial protein synthesis. The brain, especially the hippocampus, is highly susceptible to mitochondrial dysfunction; hence, the maintenance of mitochondrial activity is strongly required to prevent disorders associated with hippocampal malfunction. To study the role of ALKBH1 in the hippocampus, we generated dorsal telencephalon-specific Alkbh1 conditional knockout (cKO) mice in inbred C57BL/6 background. These mice showed reduced activity of the respiratory chain complex, hippocampal atrophy, and CA1 pyramidal neuron abnormalities. Furthermore, performances in the fear-conditioning and Morris water maze tests in cKO mice indicated that the hippocampal abnormalities led to impaired hippocampus-dependent learning. These findings indicate critical roles of ALKBH1 in the hippocampus. To assess the effectiveness in preventing cesarean section for failed induction by using Foley catheter for cervical ripening in comparison to Foley catheter with a weight attached to it. A randomized control trial conducted between November 2018 and July 2020, which looked at induction of labor with 30-ml Foley catheter in one arm and the Foley placed with a 500ml weight attached to it in the other arm. Primary outcome was the cesarean section rate. We randomized 399 women. Modes of delivery were similar in both groups. Numbers undergoing cesarean section for failed induction were higher in the group that underwent induction with Foley with weight but this was not statistically significant (45.7% vs 26.5%, P=0.1). There was a shorter time to expulsion of the Foley with weight attached (mean±standard deviation 2.6±3.3h vs 10.9±3.2h, P<0.001) but this did not translate into a difference in time to active labor or time to delivery. Placing a weight at the end of the Foley catheter for induction of labor does not affect the time to delivery or the rate of cesarean deliveries, although there is faster expulsion of the Foley. Clinical trial registration no. CTRI/2018/10/016154.

Progranulin (PGRN), a neurotrophic factor expressed mainly in neurons and microglia, has various neuroprotective effects such as anti-inflammatory effects, promoting neuron survival and neurite growth, and participating in normal lysosomal function. Mutations in the PGRN gene (GRN) have been found in several neurodegenerative dementias, including frontotemporal lobar degeneration (FTLD) and Alzheimer's disease (AD). Herein, PGRN deficiency and PGRN hydrolytic products (GRNs) in the pathological changes related to dementia, including aggregation of tau and TAR DNA-binding protein 43 (TDP-43), amyloid-β (Aβ) overproduction, neuroinflammation, lysosomal dysfunction, neuronal death, and synaptic deficit have been summarized. Furthermore, as some therapeutic strategies targeting PGRN have been developed in various models, we highlighted PGRN as a potential anti-neurodegeneration target in dementia. Besides reducing the quality of obstetric care, the direct impact of COVID-19 on pregnancy and postpartum is uncertain. To evaluate the characteristics of pregnant women who died due to COVID-19. Cochrane Library, Embase, MEDLINE, Scopus, and Google Scholar were searched from inception to February 2021. Studies that compared deceased and survived pregnant women with COVID-19. Relevant data were extracted and tabulated. The primary outcome was maternal co-morbidity. Thirteen studies with 154 deceased patients were included. Obesity doubled the risk of death (relative risk [RR] 2.48, 95% confidence interval [CI] 1.41-4.36, I =0%). No differences were found for gestational diabetes (RR 5.71; 95% CI 0.77-42.44, I =94%) or asthma (RR 2.05, 95% CI 0.81-5.15, I =0%). Overall, at least one severe co-morbidity showed a twofold increased risk of death (RR 2.26, 95% CI 1.77-2.89, I =76%). Admission to intensive care was related to a fivefold increased risk of death (RR 5.09, 95% CI 2.00-12.98, I =56%), with no difference in need for respiratory support (RR 0.
