Human scalp skin and hair follicles express neurotophin-3 and its high- affinity receptor tyrosine kinase C, and show hair cycle-dependent alterations in expression.

2005 | Keywords human scalp skin, tyrosine kinase C (Trk C), Neurotrophin (NT)‐3,
Human scalp skin and hair follicles express neurotophin-3 and its high- affinity receptor tyrosine kinase C, and show hair cycle-dependent alterations in expression.
BACKGROUND Neurotrophin (NT)‐3 and its high‐affinity receptor tyrosine kinase C (Trk C) are essential for nervous system development. These members of the NT family are also involved in murine hair morphogenesis and cycling. However, their role in human hair follicle (HF) biology remains to be elucidated. OBJECTIVES To explore the role of NTs in human skin and HF biology. METHODS ... Read more

Phenotypic Characterization Of The Immune And Mast Cell Infiltrates In The Human Testis Showing Normal And Abnormal Spermatogenesis.
OBJECTIVE: To assess the types, distributions, and numbers of immune cell infiltrates in the testes of men with azoospermia. DESIGN: Prospective study. SETTING: University research and clinical institutes. PATIENT(S): Thirty-one men with azoospermia showing normal spermatogenesis (n=10), germ cell maturation arrest (GA, n=12), and Sertoli cell– only syndrome (SCO, n=9). INTERVENTION(S): Testicular tissue biopsies. Sections were stained with routine (hematoxyline ... Read more

The effect of narrow band UVB therapy on serum IL-2R, IL-6 AND TNF- alpha levels in patients with vitiligo.

2005 | Keywords
The effect of narrow band UVB therapy on serum IL-2R, IL-6 AND TNF- alpha levels in patients with vitiligo.
This study was conducted to determine some of the immunological changes in Vitiligo by measuring the serum levels of IL-2R, IL-6 and TNF-α in patients with Vitiligo before and after treatment with narrow band UVB therapy for 6 months. Thirty five patients with nonsegmental Vitiligo (16 males and 19 females) aged 6 to 55 years with a mean of 27.97 ... Read more

Human scalp skin and hair follicles express neurotophin-3 (NT-3) and its high affinity receptor tyrosine kinase C (TrKC) and show hair cycle-dependent expression alterations.

2005 | Keywords : NT-3, Trk C, human, NT-3, Trk C, Human skin, Human HF,
Human scalp skin and hair follicles express neurotophin-3 (NT-3) and its high affinity receptor tyrosine kinase C (TrKC) and show hair cycle-dependent expression alterations.
Objective: neurotrophin - 3 (NT-3) and its high affinityreceptor tyrosine kinase C (TrK C) are essential for nervous system development. Recently, it has been shown thatthese members of the neurotrophin family are also involved in murine hair morhoenesis and ycling. However, their role in human hair follicle biology remains to be elucidated. As a first step towards this end, we ... Read more

2005 | Keywords Ivermectin, Crotamiton, Pediculosis humanus capitis,
Comparison between Ivermectin and Crotamiton in the Treatment of Pediculosis humanus capitis.
_T_his is a randomized clinical trial comparing between two pediculicides, oral ivermectin tablets versus topical crotamiton lotion. It was applied on 224 patients infested with Pediculus humanus capitis among 3 primary school pupils in Sohag, Egypt. They were equally divided into two groups and randomly allocated for either type of medicines. During the study 25 cases were excluded as they ... Read more

Serum Soluble Fas, Bcl-2 Proteins and IL-6 Levels in Patients with Psoriasis Vulgaris and their correlations to disease activity.

2004 | Keywords Psoriasis Vulgaris, IL-6, Bcl-2, Serum Soluble Fas,
Serum Soluble Fas, Bcl-2 Proteins and IL-6 Levels in Patients with Psoriasis Vulgaris and their correlations to disease activity.
INTRODUCTIONF: as (Apo-I /CD95) is a widely expressed membrane-anchored protein that induces apoptosis. Keratinocytes constitutively express the Fas antigen and Fas- mediated apoptosis may characterize several pathological conditions affecting human skin. Soluble Fas (sFas) has been demonstrated in serum by alternative mRNA splicing of Fas receptor. It can antagonize cell surface Fas function by downregulating Fas- mediated apoptosis and its ...
