Screening involving genetic modifications related to non-syndromic hearing problems making use of MassARRAY iPLEX® technology.
The simultaneous treatment was more effective in the down-regulation of Akt and mTOR compared to either theanine or theobromine alone. Theobromine administration also caused more inhibitory effects on the Ki-67 and Akt/mTOR expression than theanine. Besides, all dietary interventions increased the mRNA and protein expression of Smad2. In conclusion, theanine and theobromine, alone and in combination, inhibited tumorigenesis through down-regulation of the Akt/mTOR and JAK2/STAT3 pathways and an increment of the Smad2 tumor suppressor. The inhibition of the Akt/mTOR pathway was more pronounced by simultaneous treatment.Healthy aging and human longevity are intricate phenotypes affected by environmental factors such as physical exercise, diet, health habits, and psychosocial situations as well as genetic factors. Diet and caloric restriction have a crucial role in healthy aging. Curcumin, a polyphenolic compound isolated from the Curcuma longa, has been shown to exert anti-aging characteristics. Recently, investigations on curcumin with regard to aging and age-associated disease in model organisms has described that curcumin and its metabolites, prolong the mean lifespan of some aging model organisms such as C. elegans, D. melanogaster, yeast, and mouse. It has been proposed to have several biological activities, such as antioxidative, anti-inflammatory, anticancer, chemopreventive, and anti-neurodegenerative characteristics. In several studies on various model organisms it has been shown that the lifespan extension via curcumin treatment was connected with enhanced superoxide dismutase (SOD) activity, and also declined malondialdehyde (MDA) and lipofuscin levels. As well as the pivotal role of curcumin on the modulating of major signaling pathways that influence longevity of organisms like IIS, mTOR, PKA, and FOXO signaling pathways. This review defines the use of curcumin in traditional and modern medicine, its biochemistry and biological functions, such as curcumin's anti-aging, anti-cancer, anti-microbial, anti-inflammatory, and anti-oxidant characteristics. Also, the review further describes the role of curcumin in a pharmacological context and new insights on its therapeutic capacity and restrictions. Particularly, the review emphasizes in-depth on the efficiency of curcumin and its mechanism of action as an anti-aging compound and also treating age-related disease.DNA gyrase and Topoisomerase IV are promising antibacterial drug targets as they regulate bacterial DNA replication and topology. In a quest for novel DNA topoisomerase inhibitors, a multidisciplinary approach was adopted that involves computational prediction of binding sites and molecular modelling followed by green synthesis and biological evaluation of antibacterial activity of spirobenzimidazo quinazolines derivatives. Using basic quantum chemistry principles, we evaluated spirobenzimidazo quinazolines derivatives with their pharmacokinetic profiles. Based on the results of the aforesaid in-silico studies, we synthesized a series of titled compounds using green synthetic methodology that were validated as potential antimicrobial agents. Quantum chemoinformatics based predicted activity for the synthesized compounds 9b, 9c, and 9j was concomitant with biological evaluation of broadspectrum antibacterial activity. Biological evaluation revealed that inhibition of biofilm formation was due to their potential antibacterial activity. We believe that the novel spirobenzimidazo quinazolines have the potential to be alternatives to aminocoumarins and classical quinazolines upon detailed target specific biological studies.Long non-coding RNAs (lncRNAs) are RNA molecules with a transcript length of more than 200 nt and lack a protein-coding ability. They regulate gene expression by interacting with protein, RNA, and DNA. Their function is closely related to their subcellular localization. In the nucleus, lncRNAs regulate gene expression at the epigenetic and transcriptional levels, and in the cytoplasm, they regulate gene expression at the post-transcriptional and translational levels. Abnormalities in lncRNAs have been confirmed to exhibit tumor suppressor or carcinogenic effects and play an important role in the development of tumors. In particular, the lung cancer-related transcript 1 (LUCAT1) located in the antisense strand of the q14.3 region of chromosome 5 was first discovered in smoking-related lung cancer. Increasing evidence have showed that LUCAT1 is involved in breast cancer, ovarian cancer, thyroid cancer, renal cell carcinoma. It is highly expressed in liver cancer and other malignant tumors and has been confirmed to be induce various malignant tumors. It regulates tumor proliferation, invasion, and migration via various mechanisms and is related to the clinicopathological characteristics of tumor patients. Thus, LUCAT1 is a potential prognostic biological marker and therapeutic target for cancer. This article reviews its expression, function, and molecular mechanism in various malignant tumors.
The ARDS (Acute Respiratory Distress Syndrome) is a severe respiratory syndrome that was recently associated as the main death cause in the COVID-19 pandemic outbreak. Hence, in order to prevent ARDS, the pulmonary function maintenance has been the target of several pharmacological approaches. However, there is a lack of reports regarding the use of effective pharmaceutical active natural products (PANPs) for early treatment and prevention of COVID-19-related ARDS. Therefore, the aim of this work was to conduct a systematic review regarding the PANPs that could be further studied as alternatives to prevent ARDS. Consequently, this work can pave the way to spread the use of PANPs on the prevention of ARDS in COVID-19-confirmed or -suspected patients.

The search strategy included scientific studies published in English from 2015 to 2020 that promoted the elucidation of anti-inflammatory pathways targeting ARDS by in vitro and/or in vivo experiments using PANPs. selleck Then, 74 studies regarding PANPs, able to mainnally, this work highlighted the PANPs with promising potential to be used on respiratory syndromes, allowing their possible use as alternative treatment at the prevention of ARDS in COVID-19-infected or -suspected patients.
