Inpatient referrals to a specialist falls and syncope service: prevalence of STOPPFall FRIDs and review of deprescribing patterns.

Purpose: Falls are the commonest cause of accidental death in older people and the most frequent reason for their presentation to hospital. The Screening Tool of Older Persons Prescriptions in older adults with high falls risk (STOPPFall) facilitates deprescribing by providing a clear consensus on which medications are considered fall-risk-increasing drugs (FRIDs). This study aimed to determine the prevalence of STOPPFall FRIDs in inpatients referred to a falls and syncope service (FASS).

Caloric restriction of rhesus monkeys lowers oxidative damage in skeletal muscle.

In laboratory rodents, caloric restriction (CR) retards several age-dependent physiological and biochemical changes in skeletal muscle, including increased steady-state levels of oxidative damage to lipids, DNA, and proteins. We used immunogold electron microscopic (EM) techniques with antibodies raised against 4-hydroxy-2-nonenal (HNE) -modified proteins, dinitrophenol, and nitrotyrosine to quantify and localize the age-dependent accrual of oxidative damage in rhesus monkey vastus lateralis skeletal muscle. Using immunogold EM analysis of muscle from rhesus monkeys ranging in age from 2 to 34 years old, a fourfold maximal increase in levels of HNE-modified proteins was observed.

Morphologic assessment of oxidative damage: A review.

Biochemical studies have indicated changes in anti-oxidant enzyme activities and increased oxidative damage products in many disease states, particularly aging and diseases associated with aging, such as neurodegenerative diseases and cancer. To try to determine cellular and subcellular localization of oxidative damage, our laboratory has developed quantitative light and electron microscopy immunogold techniques using specific antibodies to oxidative damage products. Results from studies of different pathologic processes are presented, illustrating that both localization and quantitation of oxidative damage products is possible.

Localization of 4-hydroxy-2-nonenal-modified proteins in kidney following iron overload.

Intraperitoneal (IP) injection of ferric nitrilotriacetate (Fe-NTA) to rats and mice results in iron-induced free radical injury and cancer in kidneys. We sought to clarify the exact localization of acute oxidative damage in Fe-NTA-induced nephrotoxicity by performing immunogold light and electron microscopic (EM) techniques using an antibody against 4-hydroxy-2-nonenal (HNE)-modified proteins. Biochemical assays were done to provide complementary quantitative data.

Localization and expression of cornifin-alpha/SPRR1 in mouse epidermis, anagen hair follicles, and skin neoplasms.

Recently, cornifin-alpha/SPPR1 has been identified as a putative precursor protein of the cornified cell envelope. In this study, the expression and localization of cornifin-alpha/SPPR1 was examined in untreated and tumor promoter-treated mouse skin, hair follicles, and skin neoplasms. Western analysis with antiserum (SQ37A) to a rabbit cornifin-alpha peptide or antiserum (SQ37C) to a human SPRR1 peptide demonstrated a 31-kDa immunoreactive protein in mouse epidermis and Northern analysis revealed the presence of a 1-kb mRNA.
