Evolving dual-trait EPSP synthase variants using a synthetic yeast selection system.

The enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) functions in the shikimate pathway which is responsible for the production of aromatic amino acids and precursors of other essential secondary metabolites in all plant species. EPSPS is also the molecular target of the herbicide glyphosate. While some plant EPSPS variants have been characterized with reduced glyphosate sensitivity and have been used in biotechnology, the glyphosate insensitivity typically comes with a cost to catalytic efficiency.

Effects of various living-low and training-high modes with distinct training prescriptions on sea-level performance: A network meta-analysis.

This study aimed to separately compare and rank the effect of various living-low and training-high (LLTH) modes on aerobic and anaerobic performances in athletes, focusing on training intensity, modality, and volume, through network meta-analysis. We systematically searched PubMed, Web of Science, Embase, EBSCO, and Cochrane from their inception date to June 30, 2023. Based on the hypoxic training modality and the intensity and duration of work intervals, LLTH was divided into intermittent hypoxic exposure, continuous hypoxic training, repeated sprint training in hypoxia (RSH; work interval: 5-10 s and rest interval: approximately 30 s), interval sprint training in hypoxia (ISH; work interval: 15-30 s), short-duration high-intensity interval training (s-IHT; short work interval: 1-2 min), long-duration high-intensity interval training (l-IHT; long work interval: > 5 min), and continuous and interval training under hypoxia.

Effects of manual lymphatic drainage on total knee replacement: a systematic review and meta-analysis of randomized controlled trials.

Background: Total knee joint replacement (TKR) is an effective method for the treatment of severe knee osteoarthritis. With an increasing number of surgeries, complications such as lower limb edema, pain, and limited mobility have caused a heavy burden. Manual lymphatic drainage (MLD) may be a solution to solve the problem.

The location, physiology, pathology of hippocampus Melatonin MT receptor and MT-selective modulators.

Melatonin, a neurohormone secreted by the pineal gland and regulated by the suprachiasmatic nucleus (SCN) of the hypothalamus, is synthesized and directly released into the cerebrospinal fluid (CSF) of the third ventricle (3rdv), where it undergoes rapid absorption by surrounding tissues to exert its physiological function. The hippocampus, a vital structure in the limbic system adjacent to the ventricles, plays a pivotal role in emotional response and memory formation. Melatonin MT and MT receptors are G protein-coupled receptors (GPCRs) that primarily mediate melatonin's receptor-dependent effects.

Optimal type and dose of hypoxic training for improving maximal aerobic capacity in athletes: a systematic review and Bayesian model-based network meta-analysis.

This study aimed to compare and rank the effect of hypoxic practices on maximum oxygen consumption (VOmax) in athletes and determine the hypoxic dose-response correlation using network meta-analysis. The Web of Science, PubMed, EMBASE, and EBSCO databases were systematically search for randomized controlled trials on the effect of hypoxc interventions on the VOmax of athletes published from inception until 21 February 2023. Studies that used live-high train-high (LHTH), live-high train-low (LHTL), live-high, train-high/low (HHL), intermittent hypoxic training (IHT), and intermittent hypoxic exposure (IHE) interventions were primarily included.

Pore reconstruction mechanism of wheat straw-templated LiSiO pellets for CO capture.

The traditional LiSiO-based CO sorbent pellets prepared from mechanical granulation methods usually presented densified microstructures. Hence, wheat straw, an agricultural waste featured with huge production and low cost, was used as porosity creator to improve the microstructures and CO capture performance of LiSiO pellets. The results indicated that wheat straw effectively enhanced the cyclic CO sorption capacity of the pellets.

A Comprehensive Description of Hypoxia-inducible Factor 2α Inhibitors as Anticancer Agents: A Mini-review.

Targeting the tumor microenvironment is a promising strategy to prevent metastasis, overcome acquired drug resistance, and improve the therapeutic effect. Hypoxia is one of the characteristics of the tumor microenvironment, which is mainly regulated by hypoxia-inducible factors. Hypoxia-inducible factors (HIFs) including HIF-1α, HIF-2α, and HIF-3α, of which HIF-2α has assumed a more important role in tumor hypoxia environment.

DHW-221, a Dual PI3K/mTOR Inhibitor, Overcomes Multidrug Resistance by Targeting P-Glycoprotein (P-gp/ABCB1) and Akt-Mediated FOXO3a Nuclear Translocation in Non-small Cell Lung Cancer.

Multidrug resistance (MDR) is considered as a primary hindrance for paclitaxel failure in non-small cell lung cancer (NSCLC) patients, in which P-glycoprotein (P-gp) is overexpressed and the PI3K/Akt signaling pathway is dysregulated. Previously, we designed and synthesized DHW-221, a dual PI3K/mTOR inhibitor, which exerts a remarkable antitumor potency in NSCLC cells, but its effects and underlying mechanisms in resistant NSCLC cells remain unknown. Here, we reported for the first time that DHW-221 had favorable antiproliferative activity and suppressed cell migration and invasion in A549/Taxol cells and .

Discovery of novel tacrine derivatives as potent antiproliferative agents with CDKs inhibitory property.

Tacrine was the first approved drug by the FDA for the treatment of Alzheimer's disease (AD) but was withdrawn from the market due to its dose-dependent hepatotoxicity. Herein, we describe our efforts toward the discovery of a novel series of tacrine derivatives for cancer therapeutics. Intensive structural modifications of tacrine led to the identification of N-(4-{9-[(3S)-3-aminopyrrolidin-1-yl]-5,6,7,8-tetrahydroacridin-2-yl}pyridin-2-yl)cyclopropanecarboxamide hydrochloride ((S)-45, ZLWT-37) as a potent antiproliferative agent (GI = 0.

Machine learning-aided engineering of hydrolases for PET depolymerization.

Plastic waste poses an ecological challenge and enzymatic degradation offers one, potentially green and scalable, route for polyesters waste recycling. Poly(ethylene terephthalate) (PET) accounts for 12% of global solid waste, and a circular carbon economy for PET is theoretically attainable through rapid enzymatic depolymerization followed by repolymerization or conversion/valorization into other products. Application of PET hydrolases, however, has been hampered by their lack of robustness to pH and temperature ranges, slow reaction rates and inability to directly use untreated postconsumer plastics.

Root Extract (NRE) Alleviates Epileptiform Symptoms in PTZ-Induced Acute Seizure Mice.

Background: Epilepsy is a common neurological disorder affecting more than 70 million people worldwide. Despite numerous efforts on new antiepileptic drugs, approximately one-third of epilepsy patients suffer from uncontrolled seizures. It leads to serious psychosocial consequences, cognitive problems, and decreased quality of life.

Facile synthesis of C1-substituted β-carbolines as CDK4 inhibitors for the treatment of cancer.

Cyclin-dependent kinase 4 (CDK4), which is involved in dynamic regulation of cell cycle, has gained particularly attention for its role in controlling tumor growth.Increasing evidence showed that β-carboline derivatives have the potential to inhibit CDK4. Herein, on the basis of previous work, we designed and synthesized a series of novel β-carbolines and evaluated their antitumor activity.

A secretion-based dual fluorescence assay for high-throughput screening of alcohol dehydrogenases.

Alcohol dehydrogenases (ADHs) play key roles in the production of various chemical precursors that are essential in pharmaceutical and fine chemical industries. To achieve a practical application of ADHs in industrial processes, tailoring enzyme properties through rational design or directed evolution is often required. Here, we developed a secretion-based dual fluorescence assay (SDFA) for high-throughput screening of ADHs.
