Microtomy of Large Particle Zeolites for Tem [PDF]

MRS Proceedings, 1990
ABSTRACTUniformly thin specimens of powders, suitable for electron microscopy, can be prepared by ultramicrotomy. There is a size limit to the particles that can be studied since larger particles tend to be dislodged from the available resins when microtomed. A method is described to strengthen the binding of the organic resin to the inorganic zeolite,

Methylmercury intoxication and histochemical demonstration of NADPH-diaphorase activity in the striate cortex of adult cats

Brazilian Journal of Medical and Biological Research, 1998
The effects of methylmercury (MeHg) on histochemical demonstration of the NADPH-diaphorase (NADPH-d) activity in the striate cortex were studied in 4 adult cats. Two animals were used as control.

Age‐ and Growth‐Based Life‐History Traits of Striated Surgeonfish (Ctenochaetus striatus) and Achilles Tang (Acanthurus achilles) from Miti‘āro, Cook Islands

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Striated surgeonfish (Ctenochaetus striatus) and Achilles tang (Acanthurus achilles) are two surgeonfish species commonly harvested for subsistence on Miti‘āro, Cook Islands. Using individuals collected by local fishers, this study provides the first age‐ and growth‐based assessment of these species from Miti‘āro.

Mitigation of Hepatic and Pancreatic Injury by Spondias tuberosa Extract Through Oxidative Enzyme Modulation and TGF‐β Downregulation

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Treatment with Spondias tuberosa extract ameliorated pancreatic and hepatic morphological damage in STZ‐induced diabetic rats, potentially by reducing oxidative stress and modulating profibrotic signaling mediated by TGF‐β. ABSTRACT Diabetes mellitus (DM) is a chronic metabolic disorder marked by hyperglycemia due to impaired insulin secretion and/or ...

Current‐Generation Crosslinked Polyethylenes for Total Hip Arthroplasty: Mechanistic Insights Into Oxidative Stability and Antioxidant Efficiency

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 7, July 2026.
ABSTRACT Highly crosslinked polyethylene (XLPE) has revolutionized total hip arthroplasty (THA), but increased radiation doses and complex crosslink structures may increase oxidation susceptibility. The long‐term oxidative stability of XLPE depends on manufacturing factors, including crosslink density, antioxidant (vitamin E) concentration ...

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

Brain Pathology, Volume 36, Issue 4, July 2026.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...
