Background: The mRNA vaccine has demonstrated significant effectiveness in protecting against SARS-CoV-2 during the pandemic, including against severe forms of the disease caused by emerging variants. In this study, we examined safety, immunogenicity, and relative efficacy of a heterologous booster of the lipopolyplex (LPP)-based mRNA vaccine (SW-BIC-213) versus a homologous booster of an inactivated vaccine (BBIBP) in Laos.

Methods: In this phase 3 clinical trial, which was randomized, parallel controlled and double-blinded, healthy adults aged 18 years and above were recruited from the Southern Savannakhet Provincial Hospital and Champhone District Hospital.

Background: We assessed the safety and immunogenicity of a core-shell structured lipopolyplex (LPP) based COVID-19 mRNA vaccine, SW-BIC-213, as a heterologous booster in healthy adults.

Methods: We conducted an open-labeled, two-centered, and three-arm randomised phase 1 trial. Healthy adults, who had completed a two-dose of inactivated COVID-19 vaccine for more than six months, were enrolled and randomized to receive a booster dose of COVILO (inactivated vaccine) (n = 20) or SW-BIC-213-25μg (n = 20), or SW-BIC-213-45μg (n = 20).

Article Synopsis
  • Berberine8998 is a new derivative of berberine that shows enhanced lipid-lowering effects and better absorption compared to standard berberine.
  • In a study with hamsters on a high-fat diet, berberine8998 significantly reduced total cholesterol, triglycerides, and LDL-C levels, indicating its effectiveness in managing lipid levels.
  • Mechanistic analyses revealed differences in specific proteins related to fatty acid metabolism and showed that berberine8998's absorption was 6.7 times better than berberine, highlighting its potential as a treatment for high cholesterol and obesity.

Article Synopsis
  • Betulin, a compound derived from birch tree bark, shows potential anti-cancer and anti-malaria effects, and this study investigates its impact on atherosclerosis in apoE mice.
  • The research involves testing betulin on macrophage cell lines and analyzing changes in cholesterol accumulation, efflux, and the expression of specific transporters (ABCA1 and ABCG1) that help regulate cholesterol levels.
  • Results indicate that betulin reduces atherosclerotic lesions in mice on a high-fat diet by enhancing cholesterol efflux from macrophages and improving overall lipid profiles.

Aim: Expression of liver low-density lipoprotein receptor (LDLR), a determinant regulator in cholesterol homeostasis, is tightly controlled at multiple levels. The aim of this study was to examine whether proteasome inhibition could affect LDLR expression and LDL uptake in liver cells in vitro.

Methods: HepG2 cells were examined.

The proliferation of vascular smooth muscle cells may perform a crucial role in the pathogenesis of diabetic vascular disease. AMPK additionally exerts several salutary effects on vascular function and improves vascular abnormalities. The current study sought to determine whether sodium tanshinone IIA silate (STS) has an inhibitory effect on vascular smooth muscle cell (VSMC) proliferation and migration under high glucose conditions mimicking diabetes without dyslipidemia, and establish the underlying mechanism.

Aim: Huperzine A isolated from the Chinese herb Huperzia serrata (Thunb) Trev is a novel reversible and selective AChE inhibitor. The aim of this study was to evaluate the pharmacokinetics and tolerance of single and multiple doses of ZT-1, a novel analogue of huperzine A, in healthy Chinese subjects.

Methods: This was a double-blinded, placebo-controlled, randomized, single- and multiple-dose study.

A simple, reliable and sensitive liquid chromatography-isotope dilution mass spectrometry (LC-ID/MS) was developed and validated for quantification of olanzapine in human plasma. Plasma samples (50 microL) were extracted with tert-butyl methyl ether and isotope-labeled internal standard (olanzapine-D3) was used. The chromatographic separation was performed on XBridge Shield RP 18 (100 mm x 2.

Fentanyl is a potent analgesic drug in relieving chronic pain in patients. In this report, we present a simple, reliable and sensitive LC-ID/MS method for the quantification of fentanyl in human plasma. LC-ID/MS analysis was carried out on a triple quadrupole mass spectrometer operated in positive electrospray ionization multiple-reaction-monitoring using the transitions m/z 337.
