research Telogen effluvium after oral albendazole
A woman experienced temporary hair loss after taking albendazole, which resolved on its own within 3 months.
research Alopecia in three macaque species housed in a laboratory environment
Different monkey species in a lab showed varying levels of hair loss due to factors like type, sex, age, season, and living conditions.
research Evaluating hair growth promoting effects of candidate substance: A review of research methods
The document concludes that while lab results for hair growth promotion are promising, human trials are needed and better testing methods should be developed.
research Development of a Liquid Chromatography/Mass Spectrometry-Based Inhibition Assay for the Screening of Steroid 5-α Reductase in Human and Fish Cell Lines
A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.
research Ex vivo dermatoscopy of scalp specimens and slides
Ex vivo dermatoscopy may lower lab costs and improve diagnosis speed for hair loss biopsies.
research Ascorbigen Induces Dermal Papilla Cell Proliferation in Vitro , but Fails to Modulate Chemotherapy-Induced Alopecia in Vivo
Ascorbigen increases hair cell growth in a lab setting but does not prevent hair loss from chemotherapy in mice.
research Alopecia in laboratory animals induced by a polyampholyte, polyethylene alanine
Polyethylene alanine caused hair loss in young lab animals but not in adults, with hair regrowth occurring within 20 days.
research Human pluripotent stem cell-derived skin organoids enabled pathophysiological model of Mycobacterium tuberculosis infection
Skin organoids can model tuberculosis infection and help test treatments.
research Adult spiny mice (Acomys) exhibit endogenous cardiac recovery in response to myocardial infarction
Adult spiny mice recover better from heart attacks than common lab mice.
research POINT OF CARE W RADIOLOGII
Point of Care in radiology speeds up diagnosis and treatment by performing tests where the patient is.
research Blimp1+ cells generate functional mouse sebaceous gland organoids in vitro
Single Blimp1+ cells can create functional sebaceous gland organoids in the lab.
research Reconstructed human skin shows epidermal invagination towards integrated neopapillae indicating early hair follicle formation in vitro
The experiment showed that human skin grown in the lab started to form early hair structures when special cell clusters were added.
research Dermal papilla cells induce keratinocyte tubulogenesis in culture
Skin cells can help create early hair-like structures in lab cultures.
research Towards expansion of human hair follicle stem cells in vitro
Scientists can grow human hair follicle stem cells in a lab without changing their nature, which could help treat hair loss.
research Mimicking Hair Disorders by Genetic Manipulation of Organ-Cultured Human Hair Follicles
Scientists can mimic hair disorders by altering genes in lab-grown human hair follicles, but these follicles lack some features of natural ones.
research An Unusual Case of Elevated Testosterone: When Testosterone by Dialysis Saves the Day
Equilibrium dialysis can accurately measure testosterone levels when lab results are inconsistent.
research Rethinking biotin therapy for hair, nail, and skin disorders
Biotin supplements are not proven to improve hair or nails and may interfere with medical tests.
research Unusual Presentation of Denys-Drash Syndrome in a Girl with Undisclosed Consumption of Biotin
A girl with Denys-Drash syndrome was misdiagnosed due to biotin affecting her hormone test results.
research Quantification of biotin in plasma samples by column switching liquid chromatography – tandem mass spectrometry
The document describes a way to measure biotin in blood to prevent wrong test results in hormone level testing.
research Strategies to enhance epithelial–mesenchymal interactions for human hair follicle bioengineering
Improving the environment and cell interactions is key for creating human hair in the lab.
research Spontaneous hair follicle germ (HFG) formation in vitro, enabling the large-scale production of HFGs for regenerative medicine
Researchers found a new way to create hair-growing structures in the lab that can grow hair when put into mice.
research Endogenous human skin equivalent promotes in vitro morphogenesis of follicle-like structures
Endo-HSE helps grow hair-like structures from human skin cells in the lab.
research The Androgen Receptor and Its Use in Biological Assays: Looking Toward Effect-Based Testing and Its Applications
Scientists have developed a new method to detect steroid abuse in athletes using cell-based tests, which could be the future of anti-doping methods.
research Hair follicle stem cell cultures reveal self‐organizing plasticity of stem cells and their progeny
The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.
research Answer to April 2014 Photo Quiz
Kerion, a scalp fungal infection, requires lab confirmation and is treated with antifungal medication and medicated shampoo.
research What should it take to describe a substance or product as 'sperm-safe'
Products should be called 'sperm-safe' only after thorough, well-designed tests.
research Hair as an Indicator of the Calcium and Phosphorus Status of Ponies1
Hair analysis can't determine ponies' calcium and phosphorus levels; use soil and feed tests instead.
research Detection of Nitrite in Water Using Minoxidil as a Reagent
Minoxidil detects nitrite in water, creating a simple, cheap test.
