This study aims to reveal the effect and mechanism of Dendrobii Officinalis Caulis water extract on the rat model of hyperviscosity induced by a high-sugar, high-salt, and high-fat diet. Thirty-six male SD rats were randomized into normal, model, Compound Danshen Tablets(0.5 g·kg~(-1)), and low-, medium-, and high-dose(0.

Background: Snake venom botrocetin facilitates von Willebrand factor (VWF) binding to platelet GPIbα and has been widely used for the diagnosis of von Willebrand disease and GPIb-related disorders. Botrocetin is also commonly employed for the development/characterization of antithrombotics targeting the GPIb-VWF axis.

Objectives: To explore the alternative receptor(s)/mechanisms that participate in botrocetin-induced platelet aggregation.

Article Synopsis
  • The study looked at how a substance called fucoidan interacts with platelets, which are important for blood clotting and stopping bleeding.
  • It was found that fucoidan can either help or prevent platelets from sticking together and forming clots, depending on its size.
  • The research suggests that understanding how fucoidan works could help treat issues related to blood clots in arteries.

Article Synopsis
  • * Some snakebite victims, especially those bitten by certain types of vipers, experience a decrease in platelets (which help blood clot) that doesn't go away even after treatment with antivenom.
  • * The study found that proteins in viper venom can cause a reaction that leads to the loss of platelets in patients, suggesting that stopping this reaction might help treat the low platelet count from snakebites.

We report herein the facile and practical construction of α,β-unsaturated ketones via rhodium-catalyzed direct acylation of vinylsilanes with readily available and abundant carboxylic acids. This protocol features access to a diverse array of synthetically useful functionalities with moderate to excellent yields. More importantly, the late-stage functionalization of pharmaceuticals was also realized with synthetically useful yield.

Background: Diffuse reduction of spleen density (DROSD) is related to cancer prognosis; however, its role in intrahepatic cholangiocarcinoma (ICC) remains unclear.

Aim: To assess the predictive value of DROSD in the prognosis of ICC after curative resection.

Methods: In this multicenter retrospective cohort study, we enrolled patients with ICC who underwent curative hepatectomy between 2012 and 2019.

Background: Liver cancer stem cells (LCSCs) play key roles in the metastasis, recurrence, and chemotherapeutic resistance of hepatocellular carcinoma (HCC). Our previous research showed that the POSTN gene is closely related to the malignant progression and poor prognosis of HCC. This study aimed to elucidate the role of POSTN in generating LCSCs and maintaining their stemness as well as the underlying mechanisms.

Objective: Efficient methods for assessing walking adaptability in individuals with Parkinson's disease (PD) are urgently needed. Therefore, this study aimed to assess C-Gait for detecting freezing of gait (FOG) in patients with early- to middle-stage PD.

Method: People with PD (PWP) diagnosis (Hoehn and Yahr stages 1-3) were recruited from April 2019 to November 2019 in Beijing Rehabilitation Hospital.

Background: Wnt-inducible signaling pathway protein 2 (WISP2) is a wnt1-induced signaling pathway protein 2. Although studies indicate that WISP2 may promote the development of various tumors, its role in ovarian cancer remains unclear. The objective of the current study was to analyze the effects of WISP2 on the proliferation and migration of ovarian cancer cells in vitro and in vivo.

Understanding the occurrence, development, and treatment of liver diseases is the main goal of hepatopathology research. Liver diseases are not only diverse but also highly heterogeneous among individuals. At present, research on liver diseases is conducted mainly through cell culture, animal models, pathological specimens, .

Unlabelled: Drought stress, a major abiotic stress, commonly occurs in metal-contaminated environments and affects crop growth and yield. In this study, we performed the first integrated phenotypic, physiological, and proteomic analysis of Brachypodium distachyon L. seedling leaves under polyethylene glycol (PEG) mock osmotic stress, cadmium (Cd), and their combined stresses.

Background: Pax8 and peroxisome proliferator-activated receptor gamma 1 gene (Pax8-PPARγ1) are important factors in tumors. Several studies have suggested that follicular thyroid cancer may arise from Pax8- PPArγ1 rearrangement. In order to have a better understanding of the association between Pax8-PPARγ1 rearrangement and follicular thyroid cancer, we conducted the presenmt meta-analysis.

Using forward genetic analysis, we identified the insertion of an intracisternal A particle (IAP) retrotransposon element in the plasma membrane calcium ATPase 2 gene (Pmca2/Atp2b2) in the joggle mouse, a novel mutant that displays ataxic gait by postnatal day 12. Expression of Pmca2 mRNA in the joggle mouse is only 5% of that in the wild type mouse. The insertion is located 15 bp downstream of the donor splice site of the exon containing the initiation codon.

The joggle mouse is a recessive ataxic mutant carrying an unknown mutation in a C3H/He (C3H)-derived chromosomal segment. Taking advantage of the mouse genome database, we selected 127 DNA microsatellite markers showing heterozygosity between C3H and C57BL/6J (B6) and a first round of screening for the joggle mutation was performed on B6-jog/+ partial congenic mice (N4). We identified 4 chromosomal regions in which 13 microsatellite markers show heterozygosity between C3H and B6.
