Lack of Consensus among Stroke Experts on the Optimal Blood Pressure Target of Acute Ischemic Stroke: Evidence from a National Survey.

Introduction: There remains a lack of consensus among physicians regarding the blood pressure (BP) management strategy for acute ischemic stroke patients; this study sought to determine current practice patterns and extension of consensus among stroke physicians after publications of several randomized controlled trials (RCTs).

Methods: An online survey of stroke clinicians registered to the Oriental Conference of Interventional Neurovascology (OCIN) platform and Enhanced Control of Hypertension and Thrombectomy Stroke Study (ENCHANTED2/MT) trail collaborators was conducted to investigate the BP management strategy after mechanical thrombectomy (MT). The survey was sent out in March 2024, extracted within 1 month, and then analyzed comprehensively using descriptive statistics.

Efficacy and Safety of Chinese Herbal Medicine in Patients with Acute Intracerebral Hemorrhage: Protocol for a Randomized Placebo-Controlled Double-Blinded Multicenter Trial.

Introduction: The popular traditional Chinese medicine (TCM) compound FYTF-919 (Zhong Feng Xing Nao prescription) may improve outcome from acute intracerebral hemorrhage (ICH) through effects on brain edema, hematoma absorption, and the immune system. This study is to assess whether FYTF-919 is safe and effective as compared to matching placebo treatment in patients with acute ICH.

Methods: The ongoing Chinese Herbal medicine in patients with Acute INtracerebral hemorrhage (CHAIN) is a multicenter, prospective, randomized, double-blind placebo-controlled trial of FYTF-919 in patients with acute ICH at 20-30 hospital sites in China.

Multi-chamber membrane capacitive deionization coupled with peroxymonosulfate to achieve simultaneous removal of tetracycline and peroxymonosulfate reaction byproducts.

Advanced oxidation technologies based on peroxymonosulfate (PMS) have been extensively applied for the degradation of antibiotics. However, the degradation process inevitably introduces SO and other sulfur-containing anions, these pollutants pose a huge threat to the water and soil environment. Addressing these concerns, this study introduced PMS oxidation into a multi-chamber membrane capacitive deionization (MC-MCDI) device to achieve simultaneous tetracycline (TC) degradation and removal of PMS reaction byproduct ions.

Identification of JUN gene and cellular microenvironment in response to PD-1 blockade treatment in lung cancer patients via single-cell RNA sequencing.

Exploring the molecular mechanisms of PD-1/PDL-1 blockade for non-small cell lung cancer (NSCLC) would facilitate understanding for tumor microenvironment (TME) and development of individualized medicine. To date, biomarkers of response to PD-1 blockade therapy were still limited. In this study, we hypothesize that cell type in the tumor microenvironment can influence the effect of PD-1 blockade immunotherapy through specific genes.

Effect of dietary supplementation with recombinant human lysozyme on growth performance, antioxidative characteristics, and intestinal health in broiler chickens.

Lysozyme is often used as a feed additive to act as an antibacterial protein that boosts the immune system of livestock and poultry while protecting against pathogens.

Removal of leftover feed shapes environmental microbiota and limits houseflies-mediated dispersion of pathogenic bacteria in sow breeding farms.

Background: Intensive swine breeding industry generates a complex environment where several microbial interactions occur and which constitutes a challenge for biosafety. Ad libitum feeding strategies and low levels of management contribute to residual and wasted feed for lactating sows, which provides a source of nutrients and microbial source for houseflies in warm climates. Due to the absence of the all-in/all-out system, the coexistence of sows of two production stages including gestating and lactating sows in the farrowing barn may have potential negative impacts.

Opinions over Targets for Blood Pressure Control after Mechanical Thrombectomy in Patients with Acute Ischemic Stroke: Baseline Survey for the ENCHANTED2/MT Trial in China.

Introduction: Although guidelines recommend a target blood pressure 185-180/105-110 mm Hg after mechanical thrombectomy for acute ischemic stroke, there is limited randomized evidence to support this level. We surveyed candidate institutions about the approach to blood pressure management in this patient group in preparation for inviting them to participate in the Enhanced Blood Pressure Control after Endovascular Thrombectomy for the Acute Ischemic Stroke Trial (ENCHANTED2/MT).

Methods: Physicians from a professional network of institutions that met mechanical thrombectomy qualification requirements were invited to participate in an online questionnaire covering basic clinical information as well as questions on blood pressure management.

Tryptophan and the innate intestinal immunity: Crosstalk between metabolites, host innate immune cells, and microbiota.

The intestinal mucosal barrier is critical for the absorption of nutrients and the health of both humans and animals. Recent publications from clinical and experimental studies have shown the importance of the nutrients-bacteria-host interaction for the intestinal homeostasis. Dysfunction of these interactions has been reported to be associated with metabolic disorders and development of intestinal diseases such as the irritable bowel syndrome and inflammatory bowel diseases.

Manipulating the transmission of vector beam with spatially polarized atomic ensemble.

Vector beams (VBs) with potential applications are successfully utilized in many fields as light sources with a spatially-varying polarization profile in recent years. Here, we study the transmission of a VB by manipulating atomic polarization via the optical pumping effect. By using hybridly and radially polarized beams as pump and probe beams in a counter-propagating configuration, we observe a four-petal pattern intensity distribution of probe beam, and the four-petal pattern rotates with the polarization state orientation of the pump beam.
