After alcohol ingestion, an amount of acetaldehyde much larger than previously appreciated by measurements in plasma is released from the splanchnic areas, travels reversibly bound to the red blood cells, and is taken up by extrahepatic tissues. The magnitude of this new modality for acetaldehyde transport is markedly enhanced in alcoholics and may contribute to acetaldehyde toxicity in extrahepatic tissues.

Linking warmer nest temperatures to reduced body size in seabird nestlings: Possible mitochondrial bioenergetic and proteomic mechanisms.
J Exp Biol
January 2025
Ornis italica, Rome, Italy.
Rapid reduction of body size in populations responding to global warming suggests the involvement of temperature-dependent physiological adjustments during growth, such as mitochondrial alterations, in the efficiency of producing metabolic energy, a process that is poorly explored, especially in endotherms. Here, we examined the mitochondrial metabolism and proteomic profile of red blood cells in relation to body size and cellular energetics in nestling shearwaters (Calonectris diomedea) developing at different natural temperatures. We found that nestlings of warmer nests had lighter bodies and smaller beaks at fledging.

January 2025
Introduction: Increasing evidence links amyloid beta (Aβ) aggregation with inflammation. This pilot study investigated the use of an immunoassay panel to map biomarker changes in patients with Alzheimer's disease (AD). Furthermore, we evaluated the stability of protein quantification after multiple freeze-thaw cycles (FTCs).

Faculty of Medicine, Hong Kong University, Hong Kong, China.
Background: Whether medium-term increased water intake alone, or in combination with co-adjuvant nonexercise interventions aimed to expand blood volume (BV), improve the human cardiovascular phenotype and cardiorespiratory fitness remains unexplored.
Objectives: The purpose of this study was to determine the medium-term impact of increased (+40%) fluid (water) intake (IFI) or IFI plus head-up sleep (IFI + HUS) on BV and the cardiovascular phenotype in healthy individuals.
Methods: Healthy adults (n = 35, age 42 ± 18 years, 51% female) matched by sex, age, body composition, physical activity, and cardiorespiratory fitness were randomly allocated to IFI or IFI + HUS for 3 months.
Cancer incidence and competing mortality risk following 15 presenting symptoms in primary care: a population-based cohort study using electronic healthcare records.

Objectives: Assessment of age, sex and smoking-specific risk of cancer diagnosis and non-cancer mortality following primary care consultation for 15 new-onset symptoms.
Methods And Analysis: Data on patients aged 30-99 in 2007-2017 were extracted from a UK primary care database (CPRD Gold), comprising a randomly selected reference group and a symptomatic cohort of patients presenting with one of 15 new onset symptoms (abdominal pain, abdominal bloating, rectal bleed, change in bowel habit, dyspepsia, dysphagia, dyspnoea, haemoptysis, haematuria, fatigue, night sweats, weight loss, jaundice, breast lump and post-menopausal bleed).Time-to-event models were used to estimate outcome-specific hazards for site-specific cancer diagnosis and non-cancer mortality and to estimate cumulative incidence up to 12 months following index consultation.
Circulating tumour cell clusters: isolation, biological significance and therapeutic implications.
BMJ Oncol

Department of Biochemistry, Southern University of Science and Technology, Shenzhen, Guangdong, China.
Circulating tumour cells (CTCs) and CTC clusters are considered metastatic precursors due to their ability to seed distant metastasis. However, navigating the bloodstream presents a significant challenge for CTCs, as they must endure fluid shear forces and resist detachment-induced anoikis. Consequently, while a large number of cells from the primary tumour may enter the circulation, only a tiny fraction will result in metastasis.
