background: human hair can be used as an inexpensive and accessible adsorbent to remove a variety of pollutants from air. although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. therefore, the aim of this study was to remove formaldehyde from synthetic contaminated air by a re...

Hair cortisol has the potential to fill the methodological void of long-term cortisol assessment while becoming a widely accepted measure in biopsychology. This review critically examines the applicability and relevance of hair cortisol measurement specifically within the field of exercise and sport science. Current measures of the HPA axis only cover a brief time period, whereas hair cortisol ...

BACKGROUND Chronic kidney disease affects one in nine Americans. Diabetes and hypertension account for nearly three quarters of all kidney failure cases. Disproportionate rates of chronic kidney disease, diabetes, and hypertension have been observed among African Americans. More than 70% of all kidney failure cases caused by diabetes and hypertension could have been prevented or delayed with he...

BACKGROUND A number of otherwise healthy women with or without clinical alopecia complain of recurrent hair loss, presumably reflecting seasonality in the growth and shedding of hair. OBJECTIVE To test the hypothesis that periodicity in hair shedding reflects seasonal changes in human hair growth. METHODS Retrospective case study over a period of 6 years of apparently healthy women with the...

BACKGROUND Several forms of ichthyosis are associated with neurologic manifestations, including Sjögren-Larsson syndrome, Refsum disease, and mental retardation-enteropathy-deafness-neuropathy-ichthyosis-keratoderma (MEDNIK) syndrome. We report a case of X-linked steroid sulfatase deficiency, ichthyosis, seizures, abnormal hair banding pattern, and unilateral polymicrogyria. OBSERVATIONS A 3-...

Background Alopecia areata (AA) affects anagen hair follicles resulting in non-scarring hair loss. Since its introduction, superficial cryotherapy has been used as one of the meaningful treatment modalities for AA. Objective The purpose of this study is to clarify the therapeutic efficacy and safety of superficial cryotherapy for treatment of AA. Methods In 19 patients with multiple bilater...

Hair follicle stem cells sustain growth and cycling of the hair follicle and are located in the permanent portion of the follicle known as the bulge. In this issue of the JCI, Ohyama et al. report the characterization of global gene expression patterns of human hair follicle stem cells after their isolation using sophisticated laser capture techniques to microdissect out bulge cells. They disco...

Naxos disease is a recessively inherited arrhythmogenic right ventricular cardiomyopathy in which the cardiac phenotype is associated with palmoplantar keratoderma and woolly hair. The hair phenotype is unique, characterized by congenital woolly, curly, rough, and light-colored scalp hair and sparse eyebrows. However, arrhythmias and severe cardiomyopathies are causes of severe life threatened ...

Gorlin syndrome (also known as basal cell nevus syndrome) is a hereditary condition characterized by development of numerous epidermal and follicular tumors. Mutations in theSHH signaling pathway are key drivers this disease. It currently unknown whether SHH mutations non-epidermal types play role phenotypes, the tumor microenvironment, or altered skin development. Through lineage tracing using...
