Single-agent Adavosertib Shows Anticancer Effects Against Colorectal Cancer Cells.

Background/aim: Colorectal cancer (CRC) is the third most common malignancy and the second most common cause of cancer-related deaths worldwide. Adavosertib (AZD1775), a small molecule inhibitor of WEE1 kinase, abrogates G/M cell cycle arrest and induces double-stranded DNA breaks. According to previous findings, adavosertib, in combination with other DNA-damaging agents, causes premature mitosis and cell death in p53-mutated cancer cells mainly via abrogation of the G/M cell cycle checkpoint.

Anaerobic glucose uptake in Pseudomonas putida KT2440 in a bioelectrochemical system.

Providing an anodic potential in a bio-electrochemical system to the obligate aerobe Pseudomonas putida enables anaerobic survival and allows the cells to overcome redox imbalances. In this setup, the bacteria could be exploited to produce chemicals via oxidative pathways at high yield. However, the absence of anaerobic growth and low carbon turnover rates remain as obstacles for the application of such an electro-fermentation technology.

Performance of pilot-scale membrane aerated biofilm reactors integrated with anoxic nano-biotechnological reactor for domestic wastewater treatment.

Membrane-aerated biofilm reactors (MABRs) have aroused increasing attention due to their excellent performance in treating wastewater, where the membranes behave as bio-carriers for microorganisms and bubbleless air diffusers. The MABR technology has not been fully commercialized due to reactor design and low total nitrogen (TN) removal efficiency at short hydraulic retention times (HRT). In this study, a hybrid system of MABR 1 integrated with an anoxic nano-biotechnological reactor filled with Granulated Nanoscale Oxyhydroxides of Fe (GNOF) media was evaluated to assess the improvement in nitrogen removal performance at 12, 10, and 4 h of HRTs.

Modelling in economic evaluation of mental health prevention: current status and quality of studies.

Background: The present study aimed to identify and critically appraise the quality of model-based economic evaluation studies in mental health prevention.

Methods: A systematic search was performed on MEDLINE, EMBASE, EconLit, PsycINFO, and Web of Science. Two reviewers independently screened for eligible records using predefined criteria and extracted data using a pre-piloted data extraction form.

Evaluation of Left Diastolic Function in Dilated Cardiomyopathy According to the 2016 ASE/EACVI Recommendations.

Objectives: To assess left ventricular diastolic function by using echocardiography in patients with dilated cardiomyopathy, and the relationship between left ventricular diastolic function and left ventricular dilatation, New York Heart Association (NYHA) heart failure index, left ventricular ejection fraction, and left ventricular fractional shortening.

Methods: A descriptive cross-sectional study was conducted on patients with primary dilated cardiomyopathy hospitalized in Hue Central Hospital from April 2018 to August 2020.

Results: The mean end-diastolic left ventricular volume was 133.

Effects of membrane relaxation rate on performance of pilot-scale membrane aerated biofilm reactors treating domestic wastewater.

The membranes of a Membrane Aerated Biofilm Reactor (MABR) function as bubble-less air diffusers and bio-carriers. Recent bench-scale experiments reported that the shape of membranes influenced the oxygen transfer and utilization rates, which in turn affected the pollutant removal performance of the MABR. In this study, two pilot-scale MABRs using multi-layer hollow fiber membranes with the relaxation rates of 0.

Agrobacterium-mediated cassava transformation for the Asian elite variety KU50.

Cassava genetic transformation has mostly been reported for African cassava varieties, but not for Asian varieties. This is the first report of cassava transformation in Asian elite varieties using friable embryogenic calli. Agrobacterium-mediated cassava transformation via friable embryogenic calli (FEC) has enabled the robust production of transgenic cassava.

The anoxic electrode-driven fructose catabolism of Pseudomonas putida KT2440.

Pseudomonas putida (P. putida) is a microorganism of interest for various industrial processes, yet its strictly aerobic nature limits application. Despite previous attempts to adapt P.

sp. nov., isolated from the sea surface microlayer in the Southwestern Pacific Ocean, and emended description of the genus .

A Gram-stain-negative, non-motile, facultatively anaerobic and rod-shaped bacterial strain, designated PAMC 28131, was isolated from a sea surface microlayer sample in the open water of the Pacific Ocean. Phylogenetic analysis of the 16S rRNA gene sequence of strain PAMC 28131 revealed an affiliation to the genus with the closest species RB16-17 (sequence similarity of 98.2 %).

Psychiatric Prodrome in Anti-NMDAR-Associated Encephalopathy: Clinical and Pathophysiologic Considerations.

Objective: To present a review of the literature on the clinical presentation and pathophysiology of anti-N-methyl-d-aspartate receptor encephalopathy (ANMDARE) with attention to both the more commonly recognized psychotic symptom prodrome and the less well-understood depressive symptom prodrome.

Data Sources: The search for clinical neuropsychiatric phenomena and proposed mechanisms involved in ANMDARE pathophysiology was conducted in PubMed. English-language articles published up to September 2019 were identified using a combination of the following search terms: N-methyl-d-aspartate, anti-NMDA receptor encephalitis, schizophrenia, psychosis, depression, major depressive disorder, bipolar I disorder, bipolar II disorder, anxiety, and posttraumatic stress disorder.

Characterizing the Anoxic Phenotype of Using a Bioelectrochemical System.

Industrial fermentation in aerobic processes is plagued by high costs due to gas transfer limitations and substrate oxidation to CO. It has been a longstanding challenge to engineer an obligate aerobe organism, such as , into an anaerobe to facilitate its industrial application. However, the progress in this field is limited, due to the poor understanding of the constraints restricting its anoxic phenotype.

The oxidoreductase p66Shc acts as tumor suppressor in BRAFV600E-transformed cells.

Metabolic reprogramming, as exemplified by the shift from oxidative phosphorylation to glycolysis, is a common feature of transformed cells. In many tumors, altered metabolism is also reflected in increased reactive oxygen species (ROS) levels, which contribute to proliferation and survival signaling. However, despite high ROS levels, cancer cells can be efficiently killed by further increasing ROS production.

Deletion of the activating NK cell receptor NKG2D accelerates rejection of cardiac allografts.

It has already been shown that neutralization of the activating NK cell receptor NKG2D in combination with co-stimulation blockade prolongs graft survival of vascularized transplants. In order to clarify the underlying cellular mechanisms, we transplanted complete MHC-disparate BALB/c-derived cardiac grafts into C57BL/6 wildtypes or mice deficient for NKG2D (Klrk1 ). Although median survival was 8 days for both recipient groups, we detected already at day 5 posttransplantation significantly greater intragraft frequencies of NKp46 NK cells in Klrk1 recipients than in wildtypes.

Time-course global expression profiles of Chlamydomonas reinhardtii during photo-biological H₂ production.

We used a microarray study in order to compare the time course expression profiles of two Chlamydomonas reinhardtii strains, namely the high H₂ producing mutant stm6glc4 and its parental WT strain during H₂ production induced by sulfur starvation. Major cellular reorganizations in photosynthetic apparatus, sulfur and carbon metabolism upon H₂ production were confirmed as common to both strains. More importantly, our results pointed out factors which lead to the higher H₂ production in the mutant including a higher starch accumulation in the aerobic phase and a lower competition between the H₂ase pathway and alternative electron sinks within the H₂ production phase.

Transcriptome for photobiological hydrogen production induced by sulfur deprivation in the green alga Chlamydomonas reinhardtii.

Photobiological hydrogen production using microalgae is being developed into a promising clean fuel stream for the future. In this study, microarray analyses were used to obtain global expression profiles of mRNA abundance in the green alga Chlamydomonas reinhardtii at different time points before the onset and during the course of sulfur-depleted hydrogen production. These studies were followed by real-time quantitative reverse transcription-PCR and protein analyses.
