Comparative study on determination methods of cadmium content in feed

open access: yesSiliao yanjiu
The experiment aimed to investigate the effects of different pre-treatment and determination methods on cadmium content in the feed. Two types of feed cadmium standard samples were treated using four pre-treatment methods, dry ashing, microwave digestion,

Single‐Cell Insights Into Pathogenic Profile of Orchitis and SREBP2‐Associated Cholesterol Dysregulation in Spermatogenic Failure

open access: yesAdvanced Science, EarlyView.
A first single‐cell atlas of human orchitis reveals coordinated germ‐cell loss, somatic niche dysfunction, and immune‐metabolic remodeling. Aberrant SREBP2 activation in testicular somatic cells emerges as a central pathogenic node, while Fatostatin‐mediated inhibition of the SREBP pathway improves spermatogenesis, fibrosis, and lipid accumulation in a

CKMT1 Counteracts VDAC1 Oligomerization‐Induced Neuronal Pyroptosis Through Steric Hindrance in Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
CKMT1 inhibits VDAC1 oligomerization via a dual‐region mechanism: its NTD interacts with the VDAC1 C‐terminal domain, while residues 1–39 sterically hinder dimerization, thereby reducing mtDNA leakage and AIM2 inflammasome activation, suppressing neuronal pyroptosis and protecting against cerebral ischemic injury. ABSTRACT Ischemic stroke is one of the

Synergistic Fluoride and Polymer‑Regulated Interfacial Engineering of NiFe‑LDH Anodes for Ampere‑Scale Natural Seawater Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
Schematic comparison of optimized F–NiFe–LDH and conventional NiFe–LDH electrodes during alkaline natural seawater oxygen evolution. The synergistic (poly)CM protective layer and fluoride‐mediated passivation suppress metal leaching, mitigate chloride‐induced corrosion, and regulate surface reconstruction, preserving catalyst integrity beyond 1000 h ...

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

open access: yesIntegrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

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

open access: yesThe 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.

Quick Determination of Rare Earth Elements in Geological Samples with Open Acid Digestion or High-pressure Closed Digestion by Inductively Coupled Plasma-Mass Spectrometry

open access: yesYankuang ceshi, 2014
Common pretreatment such as alkali fusion,open acid digestion and microwave digestion are unsuitable for the determination of rare earth elements (REEs) in geological samples. The process of the alkali fusion method is complicated.
