Application of lower hybrid (LH) current drive in tokamak plasmas can induce both co- and countercurrent directed changes in toroidal rotation, depending on the core q profile. For discharges with q(0) <1, rotation increments in the countercurrent direction are observed. If the LH-driven current is sufficient to suppress sawteeth and increase q(0) above unity, the core toroidal rotation change ...
BACKGROUND Despite the number of reported data concerning idiopathic central precocious puberty (CPP) in girls, major questions remain including its diagnosis, factors, and indications of gonadotropin releasing hormone (GnRH) analog treatment. METHODS A retrospective, single-center study was carried out on 493 girls with CPP. RESULTS Eleven girls (2.2%) were aged less than 3 years. Breast d...
INTRODUCTION Polycystic ovary syndrome (PCOS) is characterised by increased frequency of hypothalamic GnRH pulses leading to a relative increase in LH synthesis by the pituitary. As GnRH stimulation can reveal a relative LH excess, we have endeavoured to assess whether GnRH test might be useful in the diagnosis of PCOS. MATERIAL AND METHODS The study involved 185 subjects: a PCOS group, n = 1...
BACKGROUND The physiological mechanism by which bulls stimulate resumption of ovarian cycling activity in postpartum, anovular, suckled cows after calving may involve the concurrent activation of the hypothalamic-hypophyseal-ovarian (HPO) axis and hypothalamic-hypophyseal-adrenal (HPA) axis. Thus, the objectives of this experiment were to determine if characteristics of temporal patterns of cor...
Cows with ovarian follicular cysts were treated with progesterone to determine whether a reduction in LH concentrations and initiation of ovulatory follicular waves would occur. Cysts were diagnosed using transrectal ultrasonography when single follicular structures > 20 mm or multiple structures > 15 mm in diameter were present for 7 d in the presence of low progesterone concentrations. Three ...
A family of tetranuclear mixed-valent Mn(II)(2)/Mn(III)(2) complexes of type [Mn(4)(LH(2))(2)(LH)(2)(H(2)O)(x)(RCO(2))(2)](Y)2.nS has been synthesised and structurally characterised, where LH(3) = triethanolamine (N(CH(2)CH(2)OH)(3)), (R=CH(3), x=2, Y = CH(3)CO(2)-, n=2, S = H(2)O; 1), (R=C(6)H(5), x=0, Y=C(6)H(5)CO(2)-, n=1, S = CH(3)CN; 2), (R=C(2)H(5), x=0, Y=ClO(4)(-), n=0; 3). A common str...
The method of higher-order L-moments (LH-moment) was proposed as a more robust alternative compared to classical characterize extreme events. new derivation will be done for Mielke-Johnson’s Kappa and Three-Parameters Type-II (K3D-II) distributions based on the LH-moments approach. data maximum monthly rainfall Embong station in Terengganu were used case study. analyses conducted using with η=0...
Postpartum cows (n=25) were assigned randomly to receive an intramuscular injection of gonadotropin releasing hormone (GnRH; 100 /~g) at either 3, 10, 20, 30 or 40 days postpartum (five cows per group). Blood samples were collected via jugular catheter at lO-min intervals from 3 0 to +180 rain and at 30-min intervals from +180 to +420 min after GnRH. Plasma levels of luteinizing hormone (LH), e...
The objectives of this study were to determine if exposing seasonally anovular ewes to rams would alter patterns of cortisol concentrations, and if these changes are associated with changes in characteristics of LH concentrations. Seasonally anestrous ewes were assigned to be exposed to rams (RE; n=11) or wethers (NE; n=12). Blood samples were collected at 15-min intervals beginning 120 min bef...
OBJECTIVE There are few clinical investigations on the hot flushes that develop during endocrine therapy for prostate cancer in Japan, although there are many reports in the Western countries. Therefore, we evaluated the incidence of hot flushes and the association between hot flushes and clinical characteristics of prostate cancer patients receiving endocrine therapy. PATIENTS AND METHODS Si...
