Drought‐Induced Abscisic Acid Accumulation in Soybean Roots Depends on NCED Gene Expression More Than Shoot‐to‐Root ABA Transport

Plant, Cell &Environment, EarlyView.
Abstract Abscisic acid (ABA) is a key phytohormone in plant responses to water deficit. Although there is extensive evidence that roots can synthesise ABA, recent findings suggest that local synthesis in response to dehydration contributes little to the root ABA pool compared to shoot‐sourced ABA.

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).

Radioimmunoassay of unsulfated lithocholates

Journal of Lipid Research, 1977
A simple, rapid, precise radioimmunoassay for total unsulfate species of lithocholate (lithocholyglycine, lithocholyltaurine, and lithocholate) in serum is described.

Quantitative Determination and Stability of Trace Levels of Oxytocin in Human and Rhesus Macaque Urine by LC–MS/MS

Biomedical Chromatography, Volume 40, Issue 3, March 2026.
ABSTRACT Oxytocin (OT) quantification in biological samples is vital for understanding its role in social behavior, emotion, and brain development in humans and animals. Urinary OT analysis has gained attention but is challenging due to variability in matrix effects, background interference, low concentrations, and stability concerns.

Radioimmunoassay of sulfated lithocholates

Journal of Lipid Research, 1977
A sensitive, rapid radioimmunoassay for sulfated species of lithocholic acid (sulfolithocholyglycine, sulfolithocholyltaurine, and sulfolithocholic acid) was developed and used to measure the total concentration of sulfated lithocholates in serum from ...

Age-dependent expression of the erythropoietin gene in rat liver and kidneys [PDF]

, 1992
Using RNAse protection, we have made quantitative measurements of erythropoietin (EPO) mRNA in liver and kidneys of developing rats (days 1-54), to determine the relative contribution of both organs to the total EPO mRNA, to monitor changes which occur ...

Evaluating distant recurrence‐free survival and location of metastasis in HER2+ breast cancer by ER status

International Journal of Cancer, Volume 158, Issue 5, Page 1184-1192, 1 March 2026.
What's New? The prognostic significance of the presence or absence of human epidermal growth factor receptor 2 (HER2) and estrogen receptor (ER) in breast cancer is well‐established. However, the relationship of HER2 and ER with distant disease recurrence and metastasis location is less well understood.

The Development of Trait Anxiety in Nonhuman Primates During the First Year of Life

Developmental Science, Volume 29, Issue 2, March 2026.
ABSTRACT Anxious temperament (AT) is a nonhuman primate phenotype that models childhood behavioral inhibition, a prominent risk factor for anxiety disorders and stress‐related psychopathology. To understand its earliest antecedents, we characterized AT's developmental trajectory over the first year of life.

Pesticide Exposure Alters Follicle-Stimulating Hormone Levels in Mexican Agricultural Workers [PDF]

, 2005
Organophosphorous pesticides (OPs) are suspected of altering reproductive function by reducing brain acetylcholinesterase activity and monoamine levels, thus impairing hypothalamic and/or pituitary endocrine functions and gonadal processes. Our objective

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene‐Edited Xenopus Tadpoles

Journal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.
