Objectives: To evaluate the gel permeation high-performance liquid chromatography (GP-HPLC) method for determination of triglyceride (TG) levels in low-density lipoprotein (LDL) and high-density lipoprotein (HDL).
Design And Methods: The GP-HPLC and the ultracentrifugation (UC)/precipitation methods were used and compared.
Results: There was no significant difference in measured levels of LDL-triglyceride between the two methods, but the HDL-triglyceride levels measured by the GP-HPLC technique were significantly higher than the UC/precipitation one (145+/-47 mg/L and 121+/-45 mg/L respectively, n=38, p<0.0001).
Conclusions: A GP-HPLC technique provides LDL-TG levels comparable to those obtained by the UC/precipitation method.

The continuous development and application of pesticides in agriculture require robust multiresidue detection methods to guarantee food safety. This study introduces a novel method for multiresidue determination of pesticides in eggplants using the QuEChERS procedure, incorporating a clean-up step using carbon nanotubes stabilized in chitosan sponge (CNT-CS) and ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS) for analysis. Upon identifying the optimal extraction conditions, various sorbents were assessed for their efficacy in the dispersive solid-phase extraction (d-SPE).

The integrated stress response (ISR) is a cellular defense mechanism activated under stress conditions. When the ISR is activated, it slows the production of proteins, the building blocks that cells need to function. Trans-integrated stress response inhibitor (trans-ISRIB) is a compound that can reverse the effects of ISR activation, showing promise for treating neurodegenerative diseases.

Trypanocides can be used for both treatment and prophylaxis, but failure is often reported; this may occur due to resistance, substandard drugs, or inappropriate administration. This study in Tanzania aims to quantify reasons for trypanocide failure.

Background: Excessive lipogenesis of the skin triggers some dermatological concerns, such as enlarged pores, acne, and blackheads. Although topical drug treatments can offer temporary relief, their prolonged usage may lead to side effects of dryness, irritation, or allergic reactions. Consequently, the development of safer and efficacious ingredients in cosmetics for managing sebum overproduction represents a significant yet challenging endeavor.
