Nail loss might represent a new, reversible, adverse event associated with teriflunomide treatment. It shares close analogies with hair loss and thinning, known adverse events of teriflunomide. MS specialists should be aware of this possibility and evaluate treatment discontinuation.

Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare disease with a combination of short stature, bone abnormalities, premature ageing, and skin changes. Though the physical appearance of these patients is characteristic, there is little emphasis on the characteristic radiological features. In this paper, we report a 16-year-old boy with clinical and radiological features of this rare genetic disorder. He had a characteristic facial appearance with a large head, large eyes, thin nose with beaked tip, small chin, protruding ears, prominent scalp veins, and absence of hair...

A simple, rapid, and reliable headspace solid-phase microextraction (HS-SPME) procedure, reinforced by applying vacuum in the extraction vial, was developed. It was applied for the extraction of nicotine in solid samples prior to determination by gas chromatography-flame ionization detection (GC-FID). First, the surface of a narrow stainless steel wire was made porous and adhesive by platinization to obtain a durable, higher surface area, and resistant fiber. Then, a thin film of sulfonated graphene/polyaniline (Sulf-G/PANI) nanocomposite was synthesized and simultaneously coated on the platinized fiber using the electrophoretic deposition (EPD) method...

Patchy thickening and reddish discoloration of active hair growth areas of skin in rabbits are occasionally found, and this gross feature could affect precise evaluation when conducting a dermal irritation test. Since little is known about the mechanism of this phenomenon, we examined the dorsal skin of New Zealand White rabbits morphologically and immunohistochemically in order to identify the possible mechanism responsible for developing these skin changes in relation to the hair cycle. Skin samples from 4 rabbits were divided into three groups (5 samples/group) based on their macroscopic characteristics: a thickened skin, erythematous skin, and smooth skin group...

Melanocytic matricoma is a recently described cutaneous adnexal tumor composed of matrical and supramatrical cells admixed with pigmented dendritic melanocytes, thought to recapitulate the anagen bulb of the hair follicle. We report a case of a 75-year-old white man, which demonstrates consumption of the epidermis that is defined as thinning of the epidermis with attenuation of the basal and suprabasal layers and loss of the normal rete architecture in areas of direct contact with neoplastic cells. It has been associated with aggressive histologic features in melanoma and likely represents an early phase of ulceration due to attenuation...

BACKGROUND: Dermoscopy is a diagnostic tool that has been introduced into small animal dermatology for the evaluation of hair and the skin surface. To the best of the authors' knowledge, the use of this technique on horses and the dermoscopic appearance of equine hair and skin have yet to be reported. HYPOTHESIS/OBJECTIVES: To assess the feasibility of dermoscopy, and to describe hair and skin surface features of healthy warmblood horses. ANIMALS: Thirty four client-owned, healthy adult horses...

In their late (3(th) and 4th) larval stages, caterpillars of the myrmecophilous lycaenid (Lepidoptera) species Polyommatus coridon and P.icarus respectively, possess on their 8th abdominal segment two eversible so called tentacle organs (TOs). Previous histological and behavioural results have proposed that the TOs may release a volatile substance that elicits "excited runs" in attendant ants. In our study we investigated for the first time the temporal in- and eversion pattern of TOs. Using nerve tracing, Micro-CT, light- and electron microscopy techniques we studied (i) the histology of the 8th abdominal segment, (ii) the fine structure of the cuticular and cellular apparatus of the TOs, (iii) the attachment sites of the retractor muscle of each TO and (iv) the fine structure of the long slender tentacle hairs which are exposed to the outside, when the TOs are everted and fold back into the TO-sac during inversion...

Plantar keratodermas can arise due to a variety of genetically inherited mutations. The need to distinguish between different plantar keratoderma disorders is becoming increasingly apparent because there is evidence that they do not respond identically to treatment. Diagnosis can be aided by observation of other clinical manifestations, such as palmar keratoderma, more widespread hyperkeratosis of the epidermis, hair and nail dystrophies, or erythroderma. However, there are frequent cases of plantar keratoderma that occur in isolation...

BACKGROUND: Although perforator flaps from the pectoral branch of the thoraco-acromial (TA) axis have been well-described, there are few reports of perforator flaps based on the delto-acromial (DA) branches. We have found a reliable perforator coming off the DA branch of the TA axis, and have named a flap based on this vessel the delto-acromial perforator (DAP) flap. We describe our experience with the DAP flap together with a fresh cadaver anatomical study. METHODS: A retrospective review of all DAP flaps performed between December 2012 and January 2015 at our institution, with analysis of operative details, flap characteristics and surgical outcomes...

Acinetobacter baumannii is a ubiquitous multidrug-resistant bacteria that is found on a variety of surfaces, including skin, hair and soil. During the past decade, A. baumannii has emerged as a significant cause of nosocomial infections in the United States. Recent studies have highlighted the ability of some bacteria to utilize a wide variety of fatty acids as a membrane remodelling strategy. Considering this, we hypothesized that fatty acids may have an effect on the emerging pathogen A. baumannii. Thin-layer chromatography indicated structural alterations to major phospholipids...

Hutchinson-Gilford progeria syndrome (HGPS) is a rare genetic condition associated with mutations in the LMNA gene. This disease recapitulates some aspects of normal aging, such as hair loss, thin skin, joint stiffness, and atherosclerosis. The latter leads to heart attack or stroke that causes death at an average age of 14.6 years in children with HGPS. The typical LMNA mutation results in the production of a truncated prelamin A protein, progerin, that remains permanently farnesylated and abnormally associated with the nuclear envelope...

To use hairy roots for producing medicinal ingredients of Phytolacca americana L. we studied the factors influencing the induction and in vitro culture. Hairy roots could be incited from the veins of cut surface (morphological lower) of P. americana L. leaf explants around 18 days after infection with the strain of Agrobacterium rhizogenes ATCC15834. The highest rooting rate, 70%, was obtained when leaf explants were pre-cultured for 1 day, infected for 20 min, and co-cultured for 4 days. The transformation was confirmed by PCR amplification of rolC of Ri plasmid and silica gel thin-layer chromatography of opines from P...

Nicolaides-Baraitser syndrome (NCBRS) is a rare and well-recognized entity that was first described in 1993, with a prevalence that is currently not known. It is recognized as a distinctive entity, with some variability in its signs and symptoms. The most important characteristics include intellectual disability, peculiar facial features including sparse scalp hair, coarse facial features, low frontal hairline, and microcephaly, and seizures. Additional features may include epicanthic folds, thin upper lip vermilion with thick lower lip vermilion, skeletal abnormalities, and severe language impairment...

"I'm Jewish, you know, and my mother said, 'Always trust the rabbis.'" I never heard Mr. Weisman's refrain from his own lips. I never heard him say any words all. By the time I met him he was in a vegetative state, a man on the precipice of invisibility-white hair, thin pale limbs, melting into sheets of the same color. When I think about Mr. Weisman, I see empty spaces-the absence of his voice, the too-large bed for his shrinking frame, the always-empty chair by his bedside, and most of all, the myriad gaps in his life story...

Wound healing in the inner ear sensory epithelia is performed by the apical domains of supporting cells (SCs). Junctional F-actin belts of SCs are thin during development but become exceptionally thick during maturation. The functional significance of the thick belts is not fully understood. We have studied the role of F-actin belts during wound healing in the developing and adult cochlea of mice in vivo. We show that the thick belts serve as intracellular scaffolds that preserve the positions of surviving cells in the cochlear sensory epithelium...

Split-thickness skin grafting (STSG) is the current gold standard for treatment of extensive burn and traumatic skin injuries. However, STSG is limited by donor-site morbidity and availability, and often leads to scarring and wound contracture. Furthermore, these thin grafts lack dermal elements such as nerves and adnexa which are important in recapitulating normal skin function. Methods of fractional skin replacement either as minced STSGs or microscopic skin tissue columns have been proposed, though these techniques have not been fully characterized and lack evidence of regenerated adnexal structures...

Wetting and spreading kinetics of biological fluids has gained a substantial interest recently. The importance of these fluids in our lives has driven the pace of publications. Globally scientists have ever growing interest in understanding wetting phenomena due to its vast applications in biological fluids. It is impractical to review extremely large number of publications in the field of kinetics of complex biological fluids and cosmetic solutions on diverse surfaces. Therefore, biological and cosmetic applications of wetting and spreading dynamics are considered in the following areas: (i) Spreading of Newtonian liquids in the case of non-porous and porous substrates...

Alopecia is an uncommon manifestation of syphilis, simulating other common forms of hair-loss, but representing a crucial complaint for the patient, who might by converse have not noticed other signs and symptoms of the disease. Esthetic issues undervaluation might prolong illness, and postpone appropriate treatment. A 42-year-old patient, HIV negative, presented with a 2-month history of progressive generalized thinning of the hairs and small non-scarring irregular alopecia patches of the parietal-occipital areas of the scalp...

The organ of Corti in the cochlea is a two-cell layered epithelium: one cell layer of mechanosensory hair cells that align into one row of inner and three rows of outer hair cells interdigitated with one cell layer of underlying supporting cells along the entire length of the cochlear spiral. These two types of epithelial cells are derived from common precursors in the four- to five-cell layered primordium and acquire functionally important shapes during terminal differentiation through the thinning process and convergent extension...
