Reservoir‐Type Subcutaneous Implantable Devices Containing Porous Rate Controlling Membranes for Sustained Delivery of Risperidone

Advanced Healthcare Materials, Volume 14, Issue 26, October 7, 2025.
This study presents a novel implantable drug delivery systemwith a biodegradable poly(caprolactone) membrane and compressed drug core forsustained release. These implantable devices deliver risperidone in vitro for 170 days and in vivo for 49 days in rats, showing promise for chronic conditions like schizophrenia.

Pyrolytic formation of polyaromatic hydrocarbons from steroid hormones [PDF]

, 2011
Four steroid hormones, namely androsterone, cholesterol, estrone and estradiol, have been pyrolysed at 300, 400 and 500 °C and the pyrolysates from these have been analysed by GC-MS.

Unveiling an Alternative Mechanism for Lewis Basic Selenium as a C─H Hydrogen Bond Catalyst and Its Application in the Halogenation of Arenes

Angewandte Chemie, Volume 137, Issue 39, September 22, 2025.
This work demonstrates an unconventional mechanism in Lewis basic selenium‐catalyzed electrophilic halogenation, where in situ oxidation of selenourea by the halogen source generates hypervalent Se‐imidazolium species. These intermediates function as hydrogen‐bond catalysts to activate N‐haloamide reagents, enabling efficient and mild halogenation of ...

Enantioselective Synthesis of (+)-Estrone Exploiting a Hydrogen Bond-Promoted Diels−Alder Reaction

Journal of Organic Chemistry, 2010
Starting from Dane’s diene and methylcyclopentenedione, (+)-estrone is synthesized along the Quinkert−Dane route in 24% total yield. The key step is an enantioselective Diels−Alder reaction promoted by an amidinium catalyst as efficiently as by a ...

Astaxanthin Alleviates Lead‐Induced Toxicity by Restoring Hepatic and Gut–Liver Axis Homeostasis Through Multidimensional Metabolic and Antioxidative Pathways

Food Science &Nutrition, Volume 13, Issue 10, October 2025.
This study firstly reveals astaxanthin roles in alleviating lead toxicity in mouse via multiple approaches. Astaxanthin significantly mitigates metabolic and inflammatory imbalances through gut‐liver axis modulation. Astaxanthin activates Nrf2/ARE and PPAR pathways, providing multidimensional antioxidative and metabolic protection. Astaxanthin improves

Population Variation in Steroid Hormone‐Related Gene Expression and Sexually Dimorphic Communication in the Electric Fish Apteronotus albifrons

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 8, Page 957-975, October 2025.
ABSTRACT The development and maintenance of sexually dimorphic behavior often depends on gonadal steroids. Interspecific variation in the magnitude of behavioral sex differences may be mediated by differences in steroid action on neural circuits controlling behavior.

Synthesis of 2-Acylphenol and Flavene Derivatives from the Ruthenium-Catalyzed Oxidative C-H Acylation of Phenols with Aldehydes [PDF]

, 2015
The cationic ruthenium hydride complex [(C6H6)(PCy3)(CO)RuH]+BF4− has been found to be an effective catalyst for the oxidative C–H coupling reaction of phenols with aldehydes to give 2-acylphenol compounds.

Micropollutants and Their Interactions With Relevant Environmental Viruses

Environmental Microbiology, Volume 27, Issue 10, October 2025.
Environmental micropollutants increase virus stability. ABSTRACT Emerging pollutants encompass a diverse array of chemicals classified as micropollutants, including pharmaceuticals and microplastics (MPs). Viruses are known to adsorb onto MPs, including binding to bacterial biofilms that form the plastisphere.
