Sex Matters: Association with Superager Classification and Risk Factors.

Superagers are 80 to 89-year-olds with average or better cognition and memory equivalent to individuals 20 to 30 years younger. As sex and modifiable lifestyle/health factors influence cognitive aging and dementia risk, we examined their impact on superager status. Data from participants (n = 469; 67% female) aged 80-89 years old were analyzed from an online database that included demographic and dementia risk factors, and performance on tasks assessing working memory, cognitive inhibition, associative memory, and set shifting.

Predicting fat cover in beef cattle to make on-farm management decisions: a review of assessing fat and of modeling fat deposition.

Demands of domestic and foreign market specifications of carcass weight and fat cover, of beef cattle, have led to the development of cattle growth models that predict fat cover to assist on-farm managers make management decisions. The objectives of this paper are 4-fold: 1) conduct a brief review of the biological basis of adipose tissue accretion, 2) briefly review live and carcass assessments of beef cattle, and carcass grading systems used to develop quantitative compositional and quality indices, 3) review fat deposition models: Davis growth model (), French National Institute for Agricultural Research growth model (), Cornell Value Discovery System (), and BeefSpecs drafting tool (), and 4) appraise the process of translating science and practical skills into research/decision support tools that assist the Beef industry improve profitability. The for live and carcass animal assessments, using several techniques across a range of species and traits, ranged from 0.

Current prescribing for pyoderma gangrenosum in the UK and access to biologic medications: results from a UK Dermatology Clinical Trials Network survey of dermatologists.

Pyoderma gangrenosum (PG) is an ulcerative inflammatory disorder affecting the lower legs in 80% of patients. The use of biologic medications to treat PG is increasing, although there is a limited evidence base to guide treatment choices. In some health systems, such as the UK National Health Service, limitations are placed on biologic prescribing for PG, leading to wide variations in prescribing.

Nuclear lipid droplets in Caco2 cells originate from nascent precursors and in situ at the nuclear envelope.

Intestinal epithelial cells convert excess fatty acids into triglyceride (TAG) for storage in cytoplasmic lipid droplets and secretion in chylomicrons. Nuclear lipid droplets (nLDs) are present in intestinal cells but their origin and relationship to cytoplasmic TAG synthesis and secretion is unknown. nLDs and related lipid-associated promyelocytic leukemia structures (LAPS) were abundant in oleate-treated Caco2 but less frequent in other human colorectal cancer cell lines and mouse intestinal organoids.
