Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Sacrificial anode Fered–Fenton process for the degradation of a model naphthenic acid in high‐salinity water

The Canadian Journal of Chemical Engineering, EarlyView.
Fered–Fenton treatment of saline produced water: generation of reactive oxygen species and enhanced degradation of cyclohexane carboxylic acid through in‐situ electrochemical Fenton reactions. Abstract Offshore oilfield produced water (OPW) is a highly complex and hypersaline effluent from oil and gas extraction industry.

Iron‐Catalyzed Hydrodecarboxylation of Fatty Acids From Vegetable Oils for Drop‐In Biofuel Production

European Journal of Organic Chemistry, EarlyView.
An iron‐catalyzed hydrodecarboxylation for renewable hydrocarbon production is reported, featuring an alternative hydrogen source and a commercially available iron salt as the catalyst. The protocol enabled efficient one‐pot Cn–1 hydrocarbon synthesis from vegetable oils under mild and open‐air conditions.

Acute Modafinil Exposure Induces Neurobehavioral Alterations in Zebrafish: Implications for Off‐Label Cognitive Enhancement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Modafinil (2‐(benzhydrylsulfinyl)acetamide) is a psychostimulant commonly prescribed for sleep disorders such as narcolepsy, excessive daytime sleepiness, and obstructive sleep apnea. Recently, its use has extended beyond clinical indications, with neurotypical individuals adopting it as a smart drug to enhance alertness and cognitive ...

Cardiac Histomorphometric Implications Resulting From Chronic Nandrolone Decanoate Treatment in Rats Subjected to Resistance Training

Journal of Applied Toxicology, EarlyView.
ABSTRACT The effects of anabolic steroid abuse on the cardiac tissue of resistance training practitioners are poorly understood. Herein, we present the histomorphometric implications of resistance training in rats treated with nandrolone decanoate, an androgenic anabolic steroid. Eighteen‐week‐old male Wistar rats (N = 32) were divided into two groups (

Electrospun PVA Scaffolds Containing MCM‐41/CNC Nanocomposites for Controlled Drug Release in Wound Dressings

Polymer Engineering &Science, EarlyView.
Cellulose nanocrystals extracted from Mauritia flexuosa petiole were combined with MCM‐41 mesoporous silica to create a diclofenac‐loaded hybrid nanocomposite. Incorporation into electrospun PVA scaffolds enabled controlled diclofenac release and high cell viability, highlighting their potential for localized drug delivery.
