Hibiscus rosasinensis flower is known as hair growth promoter in traditional and folklore medicines. Petroleum ether extract of H.rosasinensis is reported in literature for hair growth promotion. The study was aimed to investigate the efficacy of ethanolic extract of H.rosa sinensis flower as hair growth promoter. Female wistar rats were selected for hair growth promotion studies. They were div...

Sox9 is a master regulatory gene involved in developmental processes, stem cells maintenance and tumorigenesis. This gene is expressed in healthy skin but even in several skin neoplasms, where its expression patterns often resembles those of the developing hair follicle. In this study, samples from eleven different types of canine skin neoplasms (squamous papilloma, squamous cell carcinoma, inf...

Background: Low-level lasers are used for various medical applications including wound healing and hair loss treatment. Cell Therapy using skin stem cells could be a novel approach to hair transplantation. However, there is no study on the effect of low-level laser on the hair follicle stem cells. So, in this study, we investigated the effect of low level laser irradiation on viability and ROS ...

A case of anaplastic, multinucleated giant cell tumor of the thyroid was studied by light and electron microscopy. The coexistence of anaplastic sarcomatous tumor and well differentiated follicular carcinoma, and the presence of desmosomes among the mononuclear cells suggested that this tumor originates in thyroid follicular cells. The multinucleated giant cells, which characterize this thyroid...

Introduction: Nowadays, cell therapy is the most advanced treatment of peripheral nerve injury. The aim of this study was to determine the effects of transplantation of hair follicle stem cells on the regeneration of the sciatic nerve injury in rats. Methods: The bulge region of the rat whisker was isolated and cultured. Morphological and biological features of the cultured bulge cells were ob...

Fig 1. Patient 1. Dermascopic image of the occipital scalp shows numerous broken hairs. Beaded hairs pathognomic of monilethrix can be seen. INTRODUCTION Monilethrix is an autosomal dominant genodermatosis characterized by hair fragility, keratosis pilaris, and pathognomonic beading of the hair shaft. Hair fragility may lead to hair breakage and the appearance of generalized hair loss. The gene...

BACKGROUND Unwanted facial and body hair is a common problem, generating a high level of interest for treatment innovations. Advances in laser technology over the past several years has led to the development and distribution of numerous red and infrared lasers and light sources to address this issue. Despite the impressive clinical results that have been reported with the use of individual las...

Follicular mucinosis is characterized by mucin deposits within the hair follicles and sebaceous glands. It can occur as a primary idiopathic benign disorder; it can be found as an incidental phenomenom in rare cases of different dermatoses; or it can arise as a secondary symptom of a malignant disorder, most commonly mycosis fungoides. Youth and localization in a single area used to be regarded...

Follicular melanocytes in bcl-2(-/-) mice have been reported to turn gray during the second hair cycle. Light microscopic analysis revealed that about half of bcl-2(-/-) mouse hair shafts had no detectable melanin granules after the second hair follicle cycle, but the remaining hair appeared to be pigmented normally. After depilation to induce new anagen hair, more than 97% of the hair shafts d...
