Acute systemic stress disrupts reproductive function by inhibiting pulsatile gonadotropin secretion. The underlying mechanism involves stress-induced suppression of the GnRH pulse generator, the functional unit of which is considered to be the hypothalamic arcuate nucleus kisspeptin/neurokinin B/dynorphin A neurons. Agonists of the neurokinin B (NKB) receptor (NK3R) have been shown to suppress ...
BACKGROUND Moderate loads with knee loading enhance bone formation, but its effects on the maintenance of the knee are not well understood. In this study, we examined the effects of knee loading on the activity of matrix metalloproteinase13 (MMP13) and evaluated the role of p38 MAPK and Rac1 GTPase in the regulation of MMP13. METHODS Knee loading (0.5-3 N for 5 min) was applied to the right k...
Background Tumor-induced angiogenesis is an imperative event in pledging new vasculature for tumor metastasis. Since overexpression of neuronal proteins gamma-synuclein (γ-Syn) and cellular prion protein (PrPC) is always detected in advanced stages of cancer diseases which involve metastasis, this study aimed to investigate whether γ-Syn or PrPC overexpression in colorectal adenocarcinoma, LS 1...
A method based on Electrical Capacitance Tomography (ECT) and an improved Least Squares Support Vector Machine (LS-SVM) is proposed for void fraction measurement of oil-gas two-phase flow. In the modeling stage, to solve the two problems in LS-SVM, pruning skills are employed to make LS-SVM sparse and robust; then the Real-Coded Genetic Algorithm is introduced to solve the difficult problem...
We report on the effect of nitrogen to rare earth (N2/RE) flux ratio structural, transport, and magnetic properties samarium nitride (SmN) dysprosium (DyN) thin films. Both materials display a reduced lattice constant when N2/RE decreases, i.e., with increased vacancies (VN) concentration. The films show several orders magnitude increase in electrical resistivity ratio. Finally, measurements Dy...
LS 5039 is a high-mass gamma-ray binary hosting compact object of unknown type. NuSTAR observed during its entire 3.9 day period. We performed periodic signal search up to 1000 Hz which did not produce credible period candidates. do see the 9.05 s candidate, originally reported by Yoneda et al. 2020 using same data, in Fourier power spectrum, but we find that statistical significance this featu...
