Identification of Metabolites of the Dietary Supplement Ingredient 5α‐Hydroxy‐Laxogenin
Drug Testing and Analysis, EarlyView.The biotransformation of the dietary supplement ingredient 5α‐hydroxy‐laxogenin was investigated using human HepG2 cells, the rat and in silico using the online software Next‐gen E‐Resource for Drug Discovery (NERDD). We identified five metabolites generated by the human HepG2 cells of which three and an additional mono‐hydroxylated metabolite were ...

An algorithm for rescaling a matrix positive definite
Linear Algebra and its Applications, 1987 Given a square matrix M, find D diagonal, so that DM is positive definite, i.e. has its field of values in the right half plane. Here it is shown that this problem can be formulated as an infinite set of linear inequalities, and solved by solving a finite sequence of linear programming problems.

Deep Underground Science and Engineering, EarlyView.In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Energy Science &Engineering, EarlyView.This study analyzes energy consumption and economic growth across 39 Sub‐Saharan African countries using a PVAR model. Findings reveal that non‐renewable energy and labor force growth stimulate economic growth, while renewable energy does not stimulate economic growth in the short run.

Exploration, EarlyView.The role of cuproptosis in HBV‐ALF was explored via bioinformatics and liver biopsy tissues. There are some crosstalks among cuproptosis, immune infiltration, and ferroptosis (The figure was created by Bio Render). ABSTRACT Hepatitis B virus (HBV) infection poses a significant challenge to global health, particularly in developing countries such as ...
