We have studied features of physical development, calciumphosphorus metabolism and mineral density of the bones in children with chronic lung diseases. Comparison of received results with the standards of physical development in children and adolescents has shown the most significant differences in ages of 10, 11 and 15 years old who had the stature level lower than average. The data obtained s...

BACKGROUND The aim of this meta-analysis was to evaluate the role of androgens or androgen-modulating agents on the probability of pregnancy achievement in poor responders undergoing IVF. METHODS Medline, EMBASE, CENTRAL, Scopus and Web of Science databases were searched for the identification of randomized controlled trials evaluating the administration of testosterone, dehydroepiandrosteron...

The molecular properties and roles of luteinizing hormone (Lh) and its receptor (Lhcgrbb) have not been studied for the medaka (Oryzias latipes), which is an excellent animal model for ovulation studies. Here, we characterized the medaka Lh/Lhcgrbb system, with attention to its involvement in the ovulatory process of this teleost fish. In the medaka ovary, follicle-stimulating hormone receptor ...

Extra nodal marginal zone B-cell lymphoma (EMZL) of the conjunctiva typically arises in the marginal zone of mucosa-associated lymphoid tissue. The pathogenesis of conjunctival EMZL remains unknown. We describe an unusual case of EMZL arising from reactive lymphoid hyperplasia (RLH) of the conjunctiva. A 35-year-old woman had fleshy salmon-pink conjunctival tumors in both eyes, oculus uterque (...

BACKGROUND Luteinizing hormone (LH) activity in human menopausal gonadotropin (hMG) preparations is derived from human chorionic gonadotropin (hCG) rather than LH. Therefore, we aimed to determine whether there are similarities in the endocrine and follicular profiles of serum and follicular fluid from controlled ovarian stimulation with the recombinant gonadotropins follicle-stimulating hormon...

Thirty patients with choroidal melanoma in whom tumour thickness was found to increase on serial examination were retrospectively studied. Often when tumours started to increase in thickness, after a period of relative quiescence, the growth rate was relatively rapid. Increased tumour thickness was associated with increased tumour growth. During the phase of active tumour growth the height of t...

BACKGROUND Based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) put on their main effects on the granulosa and theca cells. LH is essential for androgens production. Androgens are used for estradiol production by granulosa cells. Profound suppression of LH concentrations in some normogonadotropic patients can caus...

BACKGROUND Physicians in daily practice frequently attend children who present an increase in lymph node size. Care should be taken to determine which children require biopsy. Our objective was to analyze the usefulness of the peripheral lymph node biopsy in pediatric diagnosis. METHODS We reviewed histological reports of 364 lymph node biopsies. Variables were age, sex, lymphadenopathy evolu...

BACKGROUND AND PURPOSES MR imaging is now widely used to monitor disease progression in patients with multiple sclerosis (MS). The purpose of this study was to explore the relationship between disability status and existing and new MR parameters in MS patients. METHODS Forty-one patients with clinically definitive MS were studied. MR imaging included T2- and T1-weighted imaging as well as gra...
