Alopecia areata (AA) is an autoimmune-mediated, nonscarring form of hair loss. Despite its prevalence, current management options are limited, especially when the disease has progressed to alopecia totalis (AT) or alopecia universalis (AU). Recent evidence that janus kinase (JAK) signaling contributes to AA pathogenesis prompted the investigation of JAK inhibitors such as tofacitinib and ruxolitinib as possible oral treatments. However, the potential for significant adverse effects with systemic JAK inhibition makes local administration a more attractive option...

It is important to profile steroids in many physiological and pathological processes. Recently, hair has been used for the long-term measurement of endogenous steroid hormones. Analyzing hair has advantages of being noninvasive and time sequential compared with other bio-specimens. Liquid chromatography-mass spectrometry (LC-MS) techniques have been widely used over the past decades; however, it is challenging to profile estrogens in hair by LC-MS, and more comprehensive steroid profiling is required. In this paper, an ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed to simultaneously profile 28 multifunctional steroids, including corticosteroids (n = 6), estrogens (n = 13), androgens (n = 5) and progestogens (n = 4), in human scalp hair in a single run...

Tumor necrosis factor (TNF) inhibitors are used to treat Crohn disease and psoriasis. Although they are typically well tolerated, adverse effects include the development of alopecia, and paradoxically, psoriatic lesions. We recently described a woman with Crohn disease who developed alopecia and scalp psoriasis during infliximab therapy. After discontinuing infliximab and beginning oral and topical therapies, her alopecia completely resolved. We compared our experience with that of the Craddock et al. who described a woman with Crohn disease and alopecia secondary to adalimumab therapy...

BACKGROUND: Intraepidermal acantholysis is a characteristic histopathological feature of pemphigus. The histopathology of scalp biopsies in pemphigus has not been widely discussed in the literature, although the scalp is commonly involved in pemphigus. METHODS: A total of 32 consecutive patients with scalp involvement (seventeen with pemphigus vulgaris and fifteen with pemphigus foliaceus) were enrolled into the study. The histopathological examination of scalp biopsies was performed in all patients...

Panfolliculoma (PF) is a rare benign tumor with signs of differentiation toward all components of the hair follicle (HF). Cystic panfolliculoma (CPF) is a subset of PF with histological similarity to trichofolliculoma making the differential diagnosis difficult in some cases. Immunohistopathological investigations of PF have been reported; however, previous studies focused mostly on the expression profile of the outer root sheath markers. A panel of antibodies was developed and used for the detection of the expression of cytokeratin (CK) 10, CK13, CK14, CK15, hair-hard keratin (AE13), and EpCAM within the lesion, supporting the differentiation of all epithelial lineages of the HF and the diagnosis of CPF...

EAlopecia universalis (AU) is generally considered a variant of alopecia areata (AA), in which the treatment options seldom provide satisfactory results. However, successful treatment of several cases of AA and its variants with oral Janus kinase (JAK) inhibitors have been reported recently. Here we report a 23-year-old female patient with AU successfully treated with tofacitinib, a selective JAK-3 inhibitor. The initial tofacitinib dose was 5 mg twice daily. After 2 months of treatment, partial hair regrowth was seen on the scalp and eyebrows...

Fibroblast growth factor 5 (FGF5) regulates hair length in humans and a variety of other animals. To investigate whether FGF5 has similar effects in sheep, we used CRISPR/Cas9 to generate loss-of-function mutations with the FGF5 gene in Chinese Merino sheep. A total of 16 lambs were identified with genetic mutations within the targeting locus: 13 lambs had biallelic modifications and 3 lambs had monoallelic modifications. Characterization of the modifications revealed that 13 were frame shift mutations that led to premature termination; the other 3 were in-frame deletions...

In order to identify reliable markers of corneal epithelial stem cells, we employed an inducible transgenic "pulse-chase" murine model (K5Tta × TRE-H2BGFP) to localize, purify, and characterize slow cycling cells in the cornea. The retention of GFP labeling in slowly dividing cells allowed for localization of these cells to the corneal limbus and their subsequent purification by FACS. Transcriptome analysis from slow cycling cells identified differentially expressed genes when comparing to GFP(-) faster-dividing cells...

BACKGROUND: Oculocutaneous albinism (OCA) is a clinically and genetically heterogenic group of pigmentation abnormalities characterized by variable hair, skin, and ocular hypopigmentation. Six known genes and a locus on human chromosome 4q24 have been implicated in the etiology of isolated OCA forms (OCA 1-7). METHODS: The most frequent OCA types among Caucasians are OCA1, OCA2, and OCA4. We aimed to investigate genes responsible for the development of these OCA forms in Hungarian OCA patients (n = 13)...

In this paper, we describe a method for fabricating dry electrodes for use in recording electroencephalograms (EEGs), which are based on the use of chitosan (Ch), gold (Au) particles, and titanium dioxide (TiO2) nanotube arrays deposited on titanium (Ti) thin sheets. The samples were characterized by scanning electron microscopy, X-ray diffraction, electrochemical impedance spectroscopy, and EEG signal collection. The TiO2 nanotube arrays were grown on the Ti thin sheet by an electrochemical anodic oxidation method...

Phthalates are used as plasticizers to impart flexibility of plastics. Because of their toxicity, human exposure to phthalates is a concern. Little is known on the occurrence of and inhalation exposure to phthalates in indoor air. In this study, ten phthalates were measured in 97 indoor air samples collected from Northern Vietnam during September 2016 to January 2017. The mean concentrations of total phthalates (i.e., sum of ten phthalates) in particulate and gas phases ranged from 95.2 to 13,100μgg(-1) and from 57...

BACKGROUND: Nerve injury promotes release of 5-HT at the spinal cord. Once released, 5-HT may produce antinociceptive or pronociceptive effects depending of the nature of 5-HT receptors. The purpose of this study was to investigate the participation of spinal 5-HT4 and 5-HT6 receptors in the maintenance of neuropathic pain in rats. METHODS: Tactile allodynia was measured using von Frey hairs in male Wistar rats subjected to L5-L6 spinal nerve injury. Selective 5-HT4 (GR-113808, 0...

<p>Biotin, also known as Vitamin B7 or vitamin H, is a water-soluble B vitamin that acts as an essential cofactor for several carboxylases involved in the cellular metabolism of fatty acids, amino acids, and gluconeogenesis. Although there exists an incredible amount of social media hype and market advertising touting its efficacy for the improvement of hair quantity and quality, biotin's efficacy for hair remains largely unsubstantiated in scientific literature. We reviewed all pertinent scientific literature regarding the efficacy of biotin supplementation for hair growth and quality improvement, and we also investigated its popularity in society defined as a function of market analytics...

Trichotillomania is a functionally impairing, often overlooked disorder with no Food and Drug Administration-approved medications indicated for its treatment. The ability of clinical trials to detect the beneficial effects of pharmacologic treatment in trichotillomania has been hampered by the high placebo response rate. Very little is known about baseline demographic and clinical characteristics that may be predictive of placebo response in such patients. Overall, 104 participants assigned to placebo were pooled from five double-blind trials conducted at three sites in the USA and Canada...

Ototoxicity represents a major adverse side-effect of cis-diamminedichloroplatinum-II (cisplatin, CDDP). The mitogen-activated protein kinase (MAPK) pathway is thought to play a central role in potentiating the apoptotic effect of CDDP within the cochlea. We hypothesized that prophylactic inhibition of MAPK signaling, using small interfering RNA (siRNA), might confer a protective effect against CDDP-induced apoptosis within the auditory sensory epithelia. To enhance the therapeutic utility of this approach, we synthesized biocompatible siMAPK1-loaded nanoparticles (NPs) and performed physicochemical characterizations for size, morphology, and drug loading and release kinetics, using dynamic light scattering, electron microscopy and spectrophotometric analyses, respectively...
