Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

FEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Seasonal Composition Characteristics of TSP and PM2.5 Aerosols at Gosan Site of Jeju Island, Korea during 2008-2011

Asian Journal of Atmospheric Environment, 2013
The collection of TSP and PM2.5 aerosols has been made at the Gosan Site of Jeju Island during 2008-2011, and their ionic and elemental species were analyzed, in order to examine the seasonal variation and characteristics of aerosol compositions.

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

Advanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

The Influence of Three Parent Crossbreeding on the Dual Population Genetic Algortihm

Communications
A genetic algorithm (GA) is an optimization technique based on natural genetics, using selection, crossover, and mutation. Crossover combines genetic material from two parents to create offspring, maintaining diversity and preventing premature ...

A QUBO Model for the Traveling Salesman Problem with Time Windows

Algorithms, 2019
This work focuses on expressing the TSP with Time Windows (TSPTW for short) as a quadratic unconstrained binary optimization (QUBO) problem. The time windows impose time constraints that a feasible solution must satisfy. These take the form of inequality

Intravenous Tolvaptan Sodium Phosphate Can Fail to Improve Fluid Overload Due to Heart Failure in Patients With Chronic Kidney Disease: A Case Report. [PDF]

Pharmacol Res Perspect
ABSTRACT Tolvaptan is widely used as an adjunct oral diuretic to loop and thiazide diuretics for the management of fluid overload in patients with congestive heart failure. Recently, tolvaptan sodium phosphate (TSP), a water‐soluble prodrug of tolvaptan, was developed for intravenous administration and has demonstrated efficacy and safety in clinical ...

Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

Advanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.
