First-line camrelizumab (a PD-1 inhibitor) plus apatinib (an VEGFR-2 inhibitor) and chemotherapy for advanced gastric cancer (SPACE): a phase 1 study.

Patients with advanced gastric cancer typically face a grim prognosis. This phase 1a (dose escalation) and phase 1b (dose expansion) study investigated safety and efficacy of first-line camrelizumab plus apatinib and chemotherapy for advanced gastric or gastroesophageal junction adenocarcinoma. The primary endpoints included maximum tolerated dose (MTD) in phase 1a and objective response rate (ORR) across phase 1a and 1b.

Changes in Chemical Composition of Flaxseed Oil during Thermal-Induced Oxidation and Resultant Effect on DSC Thermal Properties.

To investigate the changes in chemical composition of flaxseed oil during thermal-induced oxidation and the resultant effect on thermal properties, samples with different oxidation levels were obtained by being heated at 180 °C for two hours and four hours. The oxidation degree was evaluated using peroxide value (PV), extinction coefficient at 232 nm and 268 nm (K232 and K268), and total polar compounds (TPC). Using chromatography, the fatty acid profile and triacylglycerol (TAG) profile were examined.

Effect of Apatinib Plus Pegylated Liposomal Doxorubicin vs Pegylated Liposomal Doxorubicin Alone on Platinum-Resistant Recurrent Ovarian Cancer: The APPROVE Randomized Clinical Trial.

Importance: There are substantial unmet therapeutic needs in patients with platinum-resistant recurrent ovarian cancer (PROC), and novel therapeutic strategies should be explored.

Objective: To evaluate the efficacy and safety of treatment with apatinib (a vascular endothelial growth factor receptor 2 tyrosine kinase inhibitor) plus pegylated liposomal doxorubicin (PLD) for PROC.

Design, Setting, And Participants: The APPROVE trial was performed as an open-label, randomized clinical trial at 11 hospitals in China between March 22, 2018, and November 16, 2020.

A Phase III Multicenter Randomized Clinical Trial of 60 Gy versus 50 Gy Radiation Dose in Concurrent Chemoradiotherapy for Inoperable Esophageal Squamous Cell Carcinoma.

Purpose: In this multicenter phase 3 trial, the efficacy and safety of 60 Gy and 50 Gy doses delivered with modern radiotherapy technology for definitive concurrent chemoradiotherapy (CCRT) in patients with inoperable esophageal squamous cell carcinoma (ESCC) were evaluated.

Patients And Methods: Patients with pathologically confirmed stage IIA‒IVA ESCC were randomized 1:1 to receive conventional fractionated 60 Gy or 50 Gy to the tumor and regional lymph nodes. Concurrent weekly chemotherapy (docetaxel 25 mg/m2; cisplatin 25 mg/m2) and two cycles of consolidation chemotherapy (docetaxel 70 mg/m2; cisplatin 25 mg/m2 days 1‒3) were administered.

Risk assessment approaches for evaluating cumulative exposures to multiple pesticide residues in agro-products using seasonal vegetable monitoring data from Hainan, China: a case study.

Risks from combined exposure to multiple chemicals in food have prompted a growing concern for their effect on human health. Risk management of chemical mixtures should be based on developing and harmonizing methodologies to scientifically evaluate their cumulative adverse effects. In this study, a simplified tiered approach of cumulative exposure assessment is described along with a case study of vegetables in China's Hainan province during 2012-2014.

Deletion of the Gene, Involved in the Cell Cycle, Affects Respiration and Pseudohyphal Differentiation in Saccharomyces cerevisiae.

Mbp1p is a component of MBF (MluI cell cycle box binding factor, Mbp1p-Swi6p) and is well known to regulate the G-S transition of the cell cycle. However, few studies have provided clues regarding its role in fermentation. This work aimed to recognize the function of the gene in ethanol fermentation in a wild-type industrial Saccharomyces cerevisiae strain.

Enhanced ethanol production from sugarcane molasses by industrially engineered replacement of the gene.

Replacement of a novel candidate ethanol fermentation-associated regulatory gene, , from a fast-growing strain MC15, as determined through comparative genomics analysis among three yeast strains with significant differences in ethanol yield, is hypothesised to shorten the fermentation time and enhance ethanol production from sugarcane molasses. This study sought to test this hypothesis through a novel strategy involving the transfer of the gene from a low ethanol-producing, yet fast-growing strain MC15 to a high ethanol-producing industrial strain MF01 through homologous recombination. The results indicated that in the industrially engineered strain MF01-PHO4 displayed genomic stability with a mean maximum ethanol yield that rose to 114.

Effect of Heat Exposure on Cognition in Persons with Tetraplegia.

Individuals with cervical spinal cord injury (SCI) have impaired thermoregulatory mechanisms attributed to interruption of motor, sensory, and autonomic neuropathways. To determine the effects of heat exposure on core body temperature (Tcore) and cognitive performance in persons with tetraplegia, 8 individuals with chronic tetraplegia (C3-C7, American Spinal Cord Injury Association Impairment Scale A-B) and 9 able-bodied controls were acclimated to 27°C at baseline (BL) before being exposed to 35°C for up to 120 min (Heat Challenge). Rectal temperature (Tcore), distal skin temperatures (Tsk), sweat rate (QS), microvascular skin perfusion (LDF), and plasma norepinephrine (NE) were measured.

Impact of obstructive sleep apnea and continuous positive airway pressure therapy on outcomes in patients with atrial fibrillation-Results from the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF).

Background: Obstructive sleep apnea (OSA) is common in patients with atrial fibrillation (AF). Little is known about the impact of OSA on AF treatment and long-term outcomes. We studied whether patients with OSA have a greater likelihood of progressing to more persistent forms of AF or require more hospitalizations and/or worse outcomes compared with patients without OSA.

Label-free monitoring of T cell activation by the impedance-based xCELLigence system.

T cells play a critical role in maintaining the normal function of the adaptive immune response, with their dysfunction resulting in a variety of autoimmune and immunodeficiency diseases. Efficient and accurate detection of T cell function is therefore crucial to clinical diagnosis and development of immunomodulators. A variety of in vitro cellular systems are currently employed for analyzing T cell activation, yet all suffer from some combination of low throughput, unnatural conditions and long assay times.

Dynamic monitoring of β-cell injury with impedance and rescue by glucagon-like peptide-1.

β-Cell injury plays an important role in the development of type 1 and type 2 diabetes. Most of the β-cell bioassays depend on labeling or endpoint assessments that might not capture the true physiology or pathology of the injury process. In the current study, we dynamically detected a broad range of pathological and pharmacological responses to four toxicants (cytokine mixture, free fatty acid mixture, streptozotocin, and hydrogen peroxide) in living β-cells (INS-1E and MIN6) by a label-free, cell-based assay system named xCELLigence, codeveloped by ACEA Biosciences and Roche Diagnostics.

A continued saga of Boc5, the first non-peptidic glucagon-like peptide-1 receptor agonist with in vivo activities.

Glucagon-like peptide-1 (GLP-1)-based therapy presents a promising option for treating type 2 diabetes. However, there are several limitations relative to the peptidic GLP-1 mimetics currently on the market or under development. This concern has led to a continued interest in the search for non-peptidic agonists for GLP-1 receptor (GLP-1R).

Effects of a maternal diet supplemented with chocolate and fructose beverage during gestation and lactation on rat dams and their offspring.

1. Consumption of a high-fat and high-energy diet during pregnancy leads to a risk of long-term consequences on fetal development, as well as on the postnatal health of offspring. To investigate the effects of such a diet on fetal programming, we established a high-energy intake pregnant rat model using chocolate and fructose beverage as supplements to a normal chow diet.

Initial analysis of the hemocyanin subunit type 1 (Hc1 gene) from Locusta migratoria manilensis.

Hemocyanins are copper-containing (Cu(+)) proteins that transport oxygen in many arthropods hemolymph. We characterized Hc1 gene from the grasshopper species Locusta migratoria manilensis. In particular, we cloned and sequenced the corresponding cDNAs and studied their expression at different developmental stages.
