research Estrous Cycle-Dependent Changes in Basal and Ethanol-Induced Activity of Cortical Dopaminergic Neurons in the Rat
research Defining the Cellular Environment in the Organ of Corti following Extensive Hair Cell Loss: A Basis for Future Sensory Cell Replacement in the Cochlea
This study observed that after hair cell loss in the mouse cochlea, supporting cells were replaced by migrating non-specialised cells, with genetic background affecting the rate of tissue re-organization.
research Protein-phosphatase inhibitors block root hair growth and alter cortical cell shape of Arabidopsis roots
research Mutation of the doublecortin gene in male patients with double cortex syndrome: Somatic mosaicism detected by hair root analysis
This study found that somatic mosaic mutations in the doublecortin gene may cause subcortical band heterotopia in male patients, and molecular analysis using hair roots is a useful detection method.
research THE EFFECTS OF THE SYNTHETIC AND NATURAL HORMONE OF THE ADRENAL CORTEX ON MELANIN DEPOSITION IN ADRENALECTOMIZED BLACK RATS FED DIETS ADEQUATE AND DEFICIENT IN THE FILTRATE FACTORS OF VITAMIN B1
In this study, adrenalectomy in black rats on a vitamin B-deficient diet restored hair growth and melanin deposition, effects reversed using adrenal cortical hormones.
research Mapping the accessibility of the disulfide crosslink network in the wool fiber cortex
In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.
research Adrenal 21-hydroxylase gene mutations in Slovenian hyperandrogenic women: evaluation of corticotrophin stimulation and HLA polymorphisms in screening for carrier status
This study concluded that neither basal nor ACTH-stimulated 17-OHP concentrations effectively indicate carrier status for 21-hydroxylase deficiency among Slovenian hyperandrogenic women, recommending molecular analysis of the CYP21 gene for reliable screening.
research Evaluation of Hair Characteristics and Animal Age on the Impact of Hair Cortisol Concentration in Feedlot Steers
This study found that older steers had higher hair cortisol concentrations compared to younger steers, suggesting age affects chronic stress biomarkers in beef cattle.
research Three-microneedle device as an effective option for intralesional corticosteroid administration for the treatment of alopecia areata
This abstract notes a disclaimer about supporting information and does not report new research findings.
research A detailed mapping of the readily accessible disulphide bonds in the cortex of wool fibres
This study provides insight into the specific disulfide bond interactions between keratins and keratin associated proteins, suggesting non-random cysteine interactions crucial for stabilizing hair fiber structure.
research Prenatal transplantation of epidermal neural crest stem cells in malformation of cortical development mouse model
This study suggests that prenatal infusion of epidermal neural crest stem cells may improve certain neural markers and reduce cortical injury in a mouse model of methylazoxymethanol-induced malformations.
research Body mass index across development and adolescent hair cortisol: the role of persistence, variability, and timing of exposure
research A modified FLIT-B model of trigeminal neuralgia reveals anterior cingulate cortex involvement in anxiety-like behavior in mice
In this study, researchers developed an enhanced rodent model of trigeminal neuralgia, demonstrating that structural and functional changes in the anterior cingulate cortex are linked to chronic pain and emotional disturbances, and chemogenetic inhibition of specific neurons could alleviate symptoms.
research Hormonal fluctuations under systemic stress: Investigating adolescent hair cortisol trends before and during the COVID-19 pandemic.
research Plan of analysis for the study "Maternal Hair Cortisol Concentration Trajectories throughout Pregnancy and Adverse Childhood Experiences"
This preregistered analysis plan outlines the research questions and methods for a study on maternal hair cortisol and childhood experiences but reports no new data or results.
research Plan of analysis for the study "Maternal Hair Cortisol Concentration Trajectories throughout Pregnancy and Adverse Childhood Experiences"
This study outlines its preregistered plan for analyzing maternal hair cortisol concentration during pregnancy and subsequent childhood outcomes due to adverse childhood experiences, detailing the research questions, hypotheses, and statistical methods, with results not yet reported.
research Pregnancy's lasting imprint: Late pregnancy allopregnanolone alters rat fear recall and medial prefrontal cortex activity
In this study, researchers observed that reproductive experience in female rats altered fear memory and medial prefrontal cortex (mPFC) activity, with pregnant and parous rats showing impaired fear recall compared to nulliparous controls, highlighting the influence of pregnancy-related neurosteroids on cognitive function and brain activity.
research Cedrol mitigates hepatic lipid accumulation and adipocyte hypertrophy induced by corticosteroids through the inhibition of glucocorticoid receptor activity
In this study, cedrol was found to reduce lipid accumulation in the liver and adipose tissues of dexamethasone-treated mice by antagonizing glucocorticoid receptors, suggesting its potential utility in treating dexamethasone-induced lipid metabolism disorders.
research [Changes in claw and leg health and hair cortisol concentration in dairy cows during the transition from tie-stall to free-stall housing - A study of a medium-sized farm].
This study reported that transitioning dairy cows from a tie-stall to a free-stall barn significantly reduced carpal and hock lesions, but increased stress and heel horn erosions.
research Early Psychosocial Exposures, Hair Cortisol Levels, and Disease Risk
research Effect of high-fructose diet on the renal cortex of adult male albino rats
This study found that high-fructose intake in rats led to significant kidney histological changes, such as podocyte damage and inflammatory responses, which persisted even after returning to a standard diet.
research Detection of circular RNA expression and related quantitative trait loci in the human dorsolateral prefrontal cortex
This study identified genetic, biological, and technical factors that influence circRNA expression in the human brain, connecting these factors to potential genetic risk for diseases like schizophrenia and type II diabetes.
research Comparing the efficacy of oral apremilast, intralesional corticosteroids, and their combination in patients with patchy alopecia areata: a randomized clinical controlled trial
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
This study proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.
research Probing neuronal functions with precise and targeted laser ablation in the living cortex
This study demonstrated that ablation of individual somatostatin-expressing interneurons increased activity in nearby neurons of the mouse motor cortex during motor learning.
