Adaptive responses to stress are critical to enhance physical and mental well-being, but excessive or prolonged stress may cause inadaptability and increase the risks of psychiatric disorders, such as depression. GABABR signaling is fundamental to brain function and has been identified in neuropsychiatric disorders. KCTD12 is a critical auxiliary subunit in GABABR signaling, but its role in mental disorders, such as depression is unclear. In the present study, we used a well-validated mice model, chronic social defeat stress (CSDS) to investigate behavioral responses to stress and explore the role of Kctd12 in stress response, as well as the relevant mechanisms. We found that CSDS increased the expression of Kctd12 in the dentate gyrus (DG), a subregion of hippocampus. Overexpression of Kctd12 in DG induced higher responsiveness to acute stress and increased vulnerability to social stress in mice, whereas knock-down of Kctd12 in DG prevented the social avoidance. Furthermore, an increased expression of GABAB receptor 2 (GB2) in the DG of CSDS-treated mice was observed, and CGP35348, an antagonist of GABABR, improved the stress-induced behavior responses along with suppressing the excess expression of Kctd12. In addition, Kctd12 regulated the excitability of granule cell in DG, and the stimulation of neuronal activity by silencing Kctd12 contributed to the antidepressant-like effect of fluoxetine. These findings identify that the Kctd12 in DG works as a critical mediator of stress responses, providing a promising therapeutic target in stress-related psychiatric disorders, including depression.In the past decades, the branch of complementary and alternative medicine based therapeutics has gained considerable attention worldwide. Pharmacological efficacy of various traditional medicinal plants, their products and/or product derivatives have been explored on an increasing scale. Tanshinone IIA (Tan IIA) is a pharmacologically active lipophilic component of Salvia miltiorrhiza extract. Tan IIA shares a history of high repute in Traditional Chinese Medicine. Reckoning with these, the present review collates the pharmacological properties of Tan IIA with a special emphasis on its therapeutic potential against diverse diseases including cardiovascular diseases, cerebrovascular diseases, cancer, diabetes, obesity and neurogenerative diseases. Further, possible applications of various therapeutic preparations of Tan IIA were discussed with special emphasis on nano-based drug delivery formulations. Considering the tremendous advancement in the field of nanomedicine and the therapeutic potential of Tan IIA, the convergence of these two aspects can be foreseen with great promise in clinical application.Inflammatory bowel diseases (IBD) are kind of recurrent inflammatory issues that occur in the gastrointestinal tract, and currently clinical treatment is still unideal due to the complex pathogenesis of IBD. Basically, gut barrier dysfunction is triggered by gut microbiota dysbiosis that is closely associated with the development of IBD, we thus investigated the therapeutic capacity of berberine (BBR) to improve the dysregulated gut microbiota, against IBD in rats, using a combinational strategy of targeted metabolomics and 16 s rDNA amplicon sequencing technology. Expectedly, our data revealed that BBR administration could greatly improve the pathological phenotype, gut barrier disruption, and the colon inflammation in rats with dextran sulfate sodium (DSS)-induced colitis. In addition, 16S rDNA-based microbiota analysis demonstrated that BBR could alleviate gut dysbiosis in rats. Furthermore, our targeted metabolomics analysis illustrated that the levels of microbial tryptophan catabolites in the gastrointelopment against the colitis in clinic setting.Targeted therapy for acute myeloid leukemia (AML) is an effective strategy, but currently there are very limited therapeutic targets for AML treatment. Histone lysine specific demethylase 1 (LSD1) is highly expressed in many cancers, impedes the differentiation of cancer cells, promotes the proliferation, metastasis and invasion of cancer cells, and is associated with poor prognosis. Targeting LSD1 has been recognized as a promising strategy for AML treatment in recent years. Based on these features, in the review, we discussed the main epigenetic drugs targeting LSD1 for AML therapy. Thus, this review focuses on the progress of LSD1 inhibitors in AML treatment, particularly those such as tranylcypromine (TCP), ORY-1001, GSK2879552, and IMG-7289 in clinical trials. These inhibitors provide novel scaffolds for designing new LSD1 inhibitors. Besides, combined therapies of LSD1 inhibitors with other drugs for AML treatment are also highlighted.Since time immemorial, human use medicinal plants as sources of food, therapy and industrial purpose. Classical biotechnology and recent next-generation sequencing (NGS) techniques have been successfully used to optimize plant-derived natural-products of biomedical significance. 2-MeOE2 Earlier, protein based editing tools viz. zinc-finger nucleases (ZFNs) and transcription activator-like endonucleases (TALENs) have been popularized for transcriptional level genome manipulation. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated9 (Cas9) endonuclease system is an efficient, robust and selective site-directed mutagenesis strategy for RNA-guided genome-editing. CRISPR/Cas9 genome-editing tool employs designed guide-RNAs that identifies a 3 base-pair protospacer adjacent motif (PAM) sequence occurring downstream of the target-DNA. The present review comprehensively complies the recent literature (2010-2020) retrieved from scientific-databases on the application of CRISPR/Cas9-editing-tooacilitating the production of pharmaceuticals and nutraceuticals.

Hospital managers play an essential role in implementing strategies to promote good hand hygiene (HH) among health care workers. We investigated the managers' views on their roles, challenges and developmental ideas in promoting good HH practice.

A descriptive cross-sectional study with an online survey of both medical and nursing managers was conducted within a single tertiary care hospital in Finland. Three open-ended questions were analyzed using inductive content analysis.

A total of 78 managers out of 168 responded to the survey (response rate 46%). Managers helped promote HH practices by enabling the proper environment for adherence to good HH, visible commitment, and using various means to instruct staff about HH. Challenges included the acute hospital setting and practical problems related to the managers' numerous responsibilities. Developmental ideas included information communication technology applications for monitoring HH as an indicator of the quality of care, versatile responses to HH audits, and clarifying the roles of different management levels.
