Radioimmunoassay of human plasma Lp(a) lipoprotein

Journal of Lipid Research, 1977
A quantitative immunodiffusion assay demonstrated Lp(a) lipoprotein in 91% (911 of 1000) of subjects. In order to quantitate Lp(a) in all plasma, a sensitive and specific double antibody radioimmunoassay was developed.

Postmortem Evidence of CRH Neuron Reduction in Narcolepsy Without Cataplexy With Borderline Hypocretin‐1 Levels

Journal of Sleep Research, EarlyView.
ABSTRACT Narcolepsy is classified as type 1 (NT1) or type 2 (NT2) mainly according to hypocretin deficiency rather than cataplexy. While CRH neuron loss in the PVN has been described in NT1, it remains unclear whether similar changes occur in narcolepsy without cataplexy.

Improved Glucagon Sensitivity Following Weight Loss: A Systematic Review and Meta‐Analysis

Obesity Reviews, EarlyView.
ABSTRACT Objective This systematic review and meta‐analysis investigated the effect of weight loss in people with obesity on two biomarkers of glucagon resistance: fasting plasma glucagon and alanine. Methods A comprehensive search was conducted in Medline and Embase. Random‐effects meta‐analyses and correlation analyses were performed.

The effects of spectrum, irradiance, and duration of exposure on light‐induced melatonin suppression in healthy adults

Photochemistry and Photobiology, EarlyView.
The left panel reports the measured time course data of melatonin concentration in the blood plasma of 17 BL‐Rs and 15 BL‐NRs at baseline, during a two‐hour stay in the dark, during a one‐hour light exposure to blue light, and again in the dark. The right panel shows the magnitude of melatonin concentration after 60 min of exposure to warm white, cool ...

The Effect of Lipemia on Insulin and Adiponectin Measurement in Equine Blood Samples

Veterinary Clinical Pathology, EarlyView.
ABSTRACT Background Lipemia is a common comorbidity in horses with obesity or equine metabolic syndrome, but the impact of lipemia on the measurement of insulin and adiponectin has not been evaluated. Objective To evaluate endogenous and exogenous lipemic interference with equine insulin and adiponectin measurements via several commercial assays ...

Evaluation of an Immunoturbidometric Assay for Measurement of Total Adiponectin Concentration in Equine Serum Samples

Veterinary Clinical Pathology, EarlyView.
ABSTRACT Background Total adiponectin (TA) is a marker of metabolic health in equids, with values below a critical decision point of < 7.9 μg/mL conferring increased risk of laminitis. Objectives To evaluate an IT assay to measure serum [TA] in equids and to assess its correlation with [high molecular weight adiponectin] (HMWA) measured by ELISA ...

Effects of 14 days of head‐down bed rest with or without exercise, and subsequent recovery on bone turnover, density and structure in older adults

Experimental Physiology, EarlyView.
Abstract Bed rest accelerates bone loss and may exacerbate skeletal fragility. This study examined the effects of 14 days of head‐down tilt bed rest (HDBR) with or without exercise, and subsequent recovery, on bone turnover, density and structure in older adults. Twenty‐two healthy older adults (55–65 years) completed the HDBR protocol.

Endocrine and androgenic response to altitude training in professional cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

Effects of Summer Heat Stress on Physiological Parameters and Reproductive Efficiency of Barbarine Ewes Under Natural Outdoor or Indoor Conditions

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 686-697, August 2026.
ABSTRACT Climate change and rising ambient temperatures increasingly challenge sheep production systems in arid and semi‐arid regions, particularly during the summer breeding season. This study evaluated the effects of heat stress and direct solar exposure on physiological responses, metabolic profile, and reproductive performance of Barbarine ewes, a ...
