BACKGROUND: ß -estradiol is a steroid sex hormone that plays important role in oral physiology. The aim of this study was to determin the association of the menstrual cycle and salivary ß-estradiol with the production of volatile sulfur compounds (VSC).METHODS: In this cross-sectional study, twenty female dental students in good oral and general health were recruited for evaluation of VSC, sali...

OBJECTIVE To explore the diagnostic value and measurement of serum CA-125, the single measurement of progesterone (P), ß-HCG, and estradiol (E2) in the early diagnosis of ectopic pregnancy. METHODS Serum levels of CA-125, progesterone, ß-HCG and estradiol were measured by Enzyme Linked Immuno Sorbent Assay (ELISA) techniques in 40 symptomatic women with ectopic pregnancy and 24 women with nor...

Estradiol (E2) action in the nervous system is the result of both direct nuclear and membrane-initiated signaling (EMS). E2 regulates membrane estrogen receptor-α (ERα) levels through opposing mechanisms of EMS-mediated trafficking and internalization. While ß-arrestin-mediated mERα internalization has been described in the cortex, a role of ß-arrestin in EMS, which underlies multiple physiolog...

BACKGROUND AND RATIONALE The control of Endothelin-1 (ET-1)-mediated intrahepatic vasoconstriction in cirrhosis is beneficial for the alleviation of relevant complications. Cirrhosis is accompanied by hypogonadism and altered sex hormone status. Besides, sex hormones have vasoactive effects, but it is unknown if they influence vascular function in cirrhosis. This study aimed to investigate the ...

The breeding period of Murrels in India is variable. It is well known that environmental cues play an important role in regulating reproduction in teleost fish. Choosing a successful hormone therapy involves the selection of effective hormone formulations, proper duration of hormonal treatment and timing of the hormone administration. Recent advances in chronic hormone delivery vehicle have pro...

This study aims at the effects of active immunization against chicken Vasoactive Intestinal Peptide (chVIP) on plasma prolactin (PRL) concentration, concentration of Luteinizing Hormone (LH) profile its interval and duration, progesterone (P ), estradiol (E ß), intersequence pause days and egg production in 4 2 birds during the initial stages of egg production from 20-36 weeks of egg lay in PB3...

OBJECTIVE Low grade systemic inflammation (LGSI) as well as androgen deficiency has in older men been associated with several pathologies, including cardiovascular disease (CVD). We wanted to investigate whether low testosterone levels are linked to biomarkers of LGSI already in young age, before any concurrent manifestations of CVD or other systemic diseases. DESIGN Nested cross-sectional st...

Kemik metabolizması hem fizyolojik de patolojik durumlarda karmaşık ve zorlu bir konudur. Dokunun homeostazisi büyük oranda osteoblastların osteoklastların karşılıklı aktiviteleri ile idare edilmektedir. Osteoprotegerin (OPG), başlıca osteoblastlar tarafından üretilen RANKL bağlanarak osteoklast farklılaşmasının inhibe edilmesini sağlayan tuzak reseptördür. OPG seviyesindeki düşüş yoğun aktivas...
