Article Synopsis
  • Blood-brain barrier (BBB) disruption is a key factor in the development of ischemic stroke (IS), and the effects of neferine (Nef) on this disruption are not well understood.
  • In studies using mice and brain cell models, Nef was shown to improve neurobehavioral functions, protect brain endothelial cells, and maintain BBB integrity by upregulating a protein called PGC-1α.
  • Nef reduces oxidative stress and inflammation in brain cells, promoting the repair of the BBB during IS through a specific signaling pathway involving PGC-1α.

Article Synopsis
  • * Median mercury levels were found at 12.8 µg/kg for total mercury (THg) and 6.94 µg/kg for methylmercury (MeHg), with the highest contributions from cereals (32.2%), vegetables (30.5%), and livestock (16.2%).
  • * The research concluded that cereals contributed the most to daily THg intake, while marine fish were the main source for MeHg, and indicated no health risks associated with mercury consumption from these foods for Chengdu residents (Hazard Rat

Article Synopsis
  • Metastasis is the leading cause of cancer deaths, particularly in hepatocellular carcinoma (HCC), and is linked to high blood platelet counts and tumor expression of ADAM10, which indicate poor patient prognosis.
  • Research showed that platelets increase ADAM10 expression in tumor cells through the TLR4/NF-κB signaling pathway, leading to the shedding of CX3CL1 and promoting cancer cell migration and invasion.
  • The study highlights the potential of targeting the TLR4/ADAM10/CX3CL1 axis as a strategy to inhibit platelet-driven metastasis in HCC, supported by findings from both in vitro and in vivo mouse models.

Article Synopsis
  • Cooked meat is a valuable protein source, but long cooking can produce harmful compounds called heterocyclic amines (HAs) through lipid and protein oxidation.
  • A new testing method successfully identified nine types of HAs, showing that factors like cooking temperature, time, and repeated cooking significantly affect HA levels in braised sauce beef.
  • The highest HA concentration was found after cooking the beef soup 20 times, emphasizing that high temperatures and prolonged cooking lead to greater HA formation.

Background: Non-small cell lung carcinoma (NSCLC) is one of the most common human cancers, comprising approximately 80-85% of all lung carcinomas. An estimated incidence of NSCLC is approximately 2 million new cases per year worldwide.

Results: In recent decade, the treatment of NSCLC has made breakthrough progress owing to a large number of targeted therapies which were approved for clinical use.

The effects of ultrasonic introduced by L-shaped sonotrodes made of high-temperature-resistant ceramic on the microstructure and macro-segregation of solidifying 15t AA2219 aluminum alloy ingots have been examined in the present study. The macroscopic morphology of the corrosion of the sonotrode has been observed. Grain refinement has been observed, the shape and size of the precipitated phase of the ingot were counted, and the degree of segregation along the transverse direction at 500 mm from the head of the ingot has been evaluated.

Neferine has long been recognized as a medicinal herbal ingredient with various physiological and pharmacological activities. Although previous studies have reported its antithrombotic effect, the underlying mechanisms have not been thoroughly investigated. Since platelets play a key role in thrombosis, we investigated the effects of neferine on human platelet function and the potential mechanisms.

Article Synopsis
  • - After an acute stroke affecting the corticospinal tract (CST), changes in brain structure may affect recovery and function.
  • - In a study with 22 subcortical stroke patients, MRI scans showed decreased microstructural integrity in both the affected CST and the connected precentral gyrus cortex over 6 months.
  • - Secondary degeneration was noted in the CST and precentral cortex, with a correlation between the changes in these areas suggesting that damage in the upper CST relates to alterations in the precentral gyrus.

The emergence of antibiotic resistance caused by β-lactamases, including serine β-lactamases (SβLs) and metallo-β-lactamases (MβLs), is a global public health threat. L1, a B3 subclass MβL, hydrolyzes almost all of known β-lactam antibiotics. We report a simple and straightforward UV-Vis approach for real-time activity assays of β-lactamases inside living bacterial cells, and this method has been exemplified by choosing antibiotics, L1 enzyme, Escherichia coli expressing L1 (L1 E.

Article Synopsis
  • Intravenous rtPA is an approved treatment for acute ischemic stroke within 3 hours of symptom onset, aimed at observing its effect on recanalization and clinical outcomes.
  • A study with 75 patients showed that early recanalization (ER) significantly improved symptoms compared to delayed recanalization (DR) or no recanalization (NR), with better NIHSS scores noted at 6 hours, 24 hours, and 3 months post-treatment.
  • The findings indicate that delayed recanalization may lead to worse clinical outcomes, and patients should be closely monitored during the first 6-24 hours after treatment for potential deterioration.

Article Synopsis
  • - Accurate detection of fever in children is critical for proper medical treatment, with improper definitions potentially leading to dangerous consequences.
  • - This study conducted a systematic review and meta-analysis of 25 articles to evaluate the accuracy of infrared tympanic thermometry for diagnosing pediatric fever.
  • - The results showed a pooled sensitivity of 70% and specificity of 86%, indicating that infrared tympanic thermometry is a reliable method for measuring fever and should be widely adopted in clinical settings.

The emergence and spread of antibiotic-resistant pathogens is a global public health problem. Metallo-β-lactamases (MβLs) such as New Delhi MβL-1 (NDM-1) are principle contributors to the emergence of resistance because of their ability to hydrolyze almost all known β-lactam antibiotics including penicillins, cephalosporins, and carbapenems. A clinical inhibitor of MBLs has not yet been found.

Introduction: 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside(THSG) is a water-soluble component of the rhizome extract from the traditional Chinese herb Polygonum multiflorum. Recent studies have demonstrated that THSG has potent anti-oxidative and anti-inflammatory effects. In this study, we investigated the anti-platelet aggregation, secretion and spreading of THSG with different methods.

Introduction: Neferine, a kind of isoquinoline alkaloid, extracted from the seed embryo of Nelumbo nucifera Gaertn, has long been recognized in traditional medicine as a medicinal plant with various usages. Neferine has many biological activities, including anti-hypertensive, anti-arrhythmic, negative inotropic effect and relaxation on vascular smooth muscle. Although previous studies have reported its antithrombotic effect, the mechanisms by which it exerts antithrombotic effect have not been thoroughly studied.
