1. Ischemia-modified albumin as a possible marker of oxidative stress in patients with telogen effluvium,
Abstract Background Telogen effluvium is the most common form of non-scarring alopecia characterized by diffuse hair loss. Ischemia-modified albumin is a marker of oxidative stress and inflammation. Objective The aim of this study was to compare the levels of ischemia-modified albumin of telogen effluvium patients with healthy controls. Methods Ninety-one

3. Coexistence of chronic cutaneous lupus erythematosus and frontal fibrosing alopecia
Abstract: Lupus erythemathosus is a chronic, relapsing disease with acute, subacute, and chronic lesions. Effluvium telogen occurs in the setting of systemic activity of the disease, and cicatricial alopecia results from discoid lesionsin on the scalp. Other types of alopecia, like alopecia areata, may rarely be found in lupus. Frontal fibrosing alopecia is

4. Frequency, severity and related factors of androgenetic alopecia in dermatology outpatient clinic: hospital-based cross-sectional study in Turkey
Abstract: BACKGROUND: Androgenetic alopecia (AGA) is a patterned hair loss occurring due to systemic androgen and genetic factors. It is the most common cause of hair loss in both genders. In recent years, many studies investigating the relation between systemic diseases and androgenetic alopecia presented controversial results. OBJECTIVES: In this study w

5. ANÁLISE DO COURO CABELUDO DE MULHERES COM AIDS SUBMETIDAS À AUTÓPSIA: aspectos epiteliais, foliculares e imunológicos
Introduction: Several diseases of skin and scalp (S) occur with greater clinicalseverity in individuals infected with HIV. With the emergence and effectiveness of HAART, there was a decrease in the incidence of the processes associated withimmunodeficiency, and the emergence of apparently less serious problems, such as onychodystrophy, seborrheic dermatitis

6. Effect of petroleum ether and ethanol fractions of seeds of Abrus precatorius on androgenic alopecia
Seeds of Abrus precatorius L., Fabaceae, are commonly used as purgative, emetic, aphrodisiac and in nervous disorder in traditional and folk medicines. In present study petroleum ether and ethanolic extracts of A. precatorius seeds are evaluated for reversal of androgen (testosterone by i.m route) induced alopecia in male albino wistar rats and compared to t

7. Study of the hair cycle in dogs of different coats in tropical climate in Brazil / Estudo do ciclo piloso em cães de diferentes pelames em região de clima tropical no Brasil
The hair cycle has been extensively studied in humans, sheep and laboratory animals, however there is a lack of studies on dogs. Besides varying according to the species, breed, sex and general health conditions, the hair cycle is mainly affected by climatic variations. The objective of the present work was to analyze and increase our understanding of the ha

8. An estrogen receptor pathway regulates the telogen-anagen hair follicle transition and influences epidermal cell proliferation.
The hair follicle is a cyclic, self renewing epidermal structure which is thought to be controlled by signals from the dermal papilla, a specialized cluster of mesenchymal cells within the dermis. Topical treatments with 17-beta-estradiol to the clipped dorsal skin of mice arrested hair follicles in telogen and produced a profound and prolonged inhibition of

9. Trichilemmal keratinisation: a causal factor in loosening the murine telogen club hair from the trichilemmal sac.
A quantitative histochemical study was carried out on the distribution of protein thiol and disulphide groups in the telogen follicle of mice. The histochemical demonstration of reactive groups was achieved by a method first described by Sippel (1973). The histological observations support former views on trichilemmal keratinisation that trichilemmal cells a

10. Morphological and ultrastructural aspects of the dermal papilla during the growth cycle of the vibrissal follicle in the rat.
The dermal papilla is highly implicated as the source of regulatory stimuli upon which the progression of the hair growth cycle depends. Using light and electron microscopes, the large dermal papilla of the vibrissal follicle has been studied during anagen, catagen and telogen phases of the growth cycle. The transition of the papilla from its mature anagen c

11. Transient activation of β-catenin signaling in cutaneous keratinocytes is sufficient to trigger the active growth phase of the hair cycle in mice
Wnts have key roles in many developmental processes, including hair follicle growth and differentiation. Stabilization of β-catenin is essential in the canonical Wnt signaling pathway. We developed transgenic mice expressing a regulated form of β-catenin in the skin. Chronic activation of β-catenin in resting (telogen) hair follicles resulted in changes c

12. Modeling the dynamics of human hair cycles by a follicular automaton
The hair follicle cycle successively goes through the anagen, catagen, telogen, and latency phases, which correspond, respectively, to hair growth, arrest, shedding, and absence before a new anagen phase is initiated. Experimental observations collected over a period of 14 years in a group of 10 male volunteers, alopecic and nonalopecic, allowed us to determ
