This study found that topical application of carpronium chloride led to arteriolar vasodilation and increased blood flow in rat mesenteric arterioles, without affecting systemic blood pressure.
research The Effect of the Season, the Maintenance System and the Addition of Polyunsaturated Fatty Acids on Selected Biological and Physicochemical Features of Rabbit Fur
This study found that environmental conditions significantly influenced rabbit coat quality, while dietary linseed oil supplementation changed the fatty acid profile but did not improve coat thickness or heat protection.
research In vivo effects of epidermal growth factor on epidermal pattern formation and hair follicle initiation in the marsupial bandicoot Isoodon macrourus
In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.
research Lipoatrophy and severe metabolic disturbance in mice with fat-specific deletion of PPARγ
This study found that removing PPARγ specifically from mouse adipose tissue led to severe fat loss, insulin resistance, diabetes, and associated metabolic abnormalities.
research Genome-wide detection and sequence conservation analysis of long non-coding RNA during hair follicle cycle of yak
This study identified expression patterns of long non-coding RNAs during the hair follicle cycle in yak, revealing potential functions and sequence conservation with cashmere goats.
research The Relationship Between Glycine and Gephyrin in Synapses of the Rat Spinal Cord
This study found that glycinergic synapses in the rat spinal cord are predominantly associated with gephyrin, though gephyrin may also be present at non-glycinergic synapses.
research Allergic Dermatitis in Pêga Breed Donkeys (Equus asinus) Caused by Culicoides Bites in the Amazon Biome, Pará, Brazil
This study reported allergic dermatitis in Brazilian donkeys linked to Culicoides insect bites, characterized by severe itching and skin lesions. The potential treatment with copaiba oil and multivitamin emulsion was explored, revealing its promise for managing this condition.
research Genetic Polymorphisms of the 3'-Untranslated Regions (3'-UTR) of the HSP 70 Gene in Moa Buffalo (Bubalus bubalis)
In this study, researchers identified two significant genetic polymorphisms in the 3'-UTR of the HSP70 gene in Moa buffalo, which may play an important role in heat adaptation, providing insights for conservation and performance improvement in tropical climates.
research White piedra and pediculosis capitis in the same patient
This case report highlights the simultaneous presence of white piedra, identified as T. inkin, and pediculosis capitis in one patient to emphasize their clinical distinctions.
research Analysis of genome DNA methylation at inherited coat-color dilutions of Rex Rabbits
This study found that inherited color dilution in Rex rabbit hair follicles is associated with DNA methylation changes, contributing to understanding the epigenetic regulation of rabbit pigmentation.
research LncRNA-599554 sponges miR-15a-5p to contribute inductive ability of dermal papilla cells through positive regulation of the expression of Wnt3a in cashmere goat
This study found that lncRNA-599554 contributes to the inductive ability of dermal papilla cells in cashmere goats by sponging miR-15a-5p, promoting Wnt3a expression, and potentially influencing hair follicle regeneration.
research Trps1 activates a network of secreted Wnt inhibitors and transcription factors crucial to vibrissa follicle morphogenesis
This study found that the transcription factor Trps1 acts as a novel regulator of the Wnt signaling pathway and early hair follicle progenitors in developing vibrissa follicles in mice.
research Ultrastructural immunolocalization of involucrin in the medulla and inner root sheath of the human hair
This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.
research Pmg-1 and Pmg-2 constitute a novel family of KAP genes differentially expressed during skin and mammary gland development
This study identified two novel genes, pmg-1 and pmg-2, expressed in various skin and gland tissues and potentially involved in the differentiation of epithelial cells in epidermal appendages.
research Hair loss and hypothalamic-pituitary-adrenocortical axis activity in captive rhesus macaques (Macaca mulatta).
This study found that increased hair cortisol levels, indicating stress, were associated with greater hair loss in captive rhesus macaques, although the causality of this relationship remains unclear.
research Morphogenesis- and Hair Cycle-dependent Expression of Trichohyalin, Peptidylarginine Deiminase Type III and Deiminated Trichohyalin in Rat Dorsal Skin Hair Follicles
This study observed that PAD type III and trichohyalin are expressed earlier than their deiminated form during the first and second hair cycles in rat hair follicles, indicating a potential additional factor is involved in triggering deimination.
research Spatiotemporal secondary hair follicle development in the Lanyu pig (Sus scrofa taivanus): a novel pelage hair follicle model
This study characterizes the secondary hair follicles in the Lanyu pig, an indigenous breed sharing similarities with human vellus hair follicles, suggesting its relevance as a model for researching hair follicle-mediated skin regeneration and enhancing translation to human wound healing.
research Symptoms of Chronic Ketosis in Cows and Morphobiochemical Indicators of Blood
This article describes subclinical ketosis in pregnant cows and associates it with several metabolic changes and clinical signs, reporting decreased levels of hemoglobin and glucose and increased ketone bodies.
