Aquaporins (AQPs) are membrane protein channels that allow the rapid passage of water through an epithelium containing tight junctions. In the present study, light microscope immunocytochemistry ...
Effect of Reverse Curve Mushroom Archwire on Lower Incisors in Adult Patients：A Prospective Study
Lingual orthodontic treatment Bite opening mechanism Reverse curve mushroom archwire Lower incisor intrusion
2008/12/29
This prospective clinical study was undertaken to analyze adult skeletodental changes induced by a reverse curve mushroom archwire during the initial stage of treatment. Lateral cephalograms from ...
Prenatal exposure to dexamethasone alters Leydig cell steroidogenic capacity in immature and adult rats
Testis neuroendocrine luteinizing hormone testosterone
2008/12/29
This study examines the effects of prenatal exposure to dexamethasone (DEX) on postnatal testosterone production in male rats. Pregnant female rats were treated on gestation days 14-19 with DEX (1...
Mullerian inhibiting substance inhibits testosterone synthesis in adult rats
Anti-Mu llerian hormone primary Leydig cells
2008/12/29
Mullerian inhibiting substance (MIS) is a gonadal hormone that causes regression of the Mullerian ducts during male sexual differentiation. Postnatally, MIS inhibits the proliferation and differen...
Thyroid hormone receptors in neonatal, prepubertal, and adult rat testis
Thyroid hormone receptors adult rat testis
2008/12/26
Thyroid hormone (TH) is involved in the differentiation and development of rat testis, whereas its role in adult testis function is still undefined. The aim of our work has been to further analyze the...
An Adult Case of Skeletal Open Bite with a Severely Narrowed Maxillary Dental Arch
Surgically assisted rapid maxillary expansion Transverse jaw discrepancy Narrow maxillary arch Two-stage surgery
2008/12/26
Surgically assisted rapid maxillary expansion is proposed as an efficient approach for adult patients with transverse maxillary deficiency. This article reports the treatment of an 18-year, seven-...
Stage and region-specific localization of lipocalin-type prostaglandin D synthase in the adult murine testis and epididymis
lipocalin-type prostaglandin D synthase adult murine testis epididymis
2008/12/25
Lipocalin-type prostaglandin D synthase in semen has been associated with male fertility, although this relationship is not well defined. To gain insight into potential mechanisms, the objective of ...
Differential actions of gonadotropin-releasing hormone and human chorionic gonadotropin on interstitial fluid volume and immunoglobulin G concentrations in adult rat testis
gonadotropin-releasing hormone human chorionic gonadotropin interstitial fluid volume immunoglobulin G concentrations adult rat testis
2008/12/25
Gonadotropin-releasing hormone (GnRH) agonists regulate testicular interstitial fluid (tIF) volume, most probably via specific receptors on Leydig cells. The aim of this study was to confirm the int...
Involvement of inhibin in the regulation of follicle-stimulating hormone secretion in the young adult male Shiba goat
Involvement of inhibin follicle-stimulating hormone secretion young adult male Shiba goat
2008/12/25
The roles of inhibin and testosterone in the regulation of gonadotropin secretion were investigated in young adult male Shiba goats (8-12 months of age). Plasma levels of inhibin but not testoster...
