Although idiopathic hypogonadotropic hypogonadism (IHH) has traditionally been viewed as a life-long disease caused by a deficiency of gonadotropin-releasing hormone neurons, a portion of patients may gradually regain normal reproductive axis function during hormonal replacement therapy. The predictive factors for potential IHH reversal are largely unknown.(More)
Sex differences play an important role in depression, the basis of which is an excessive stress response. We aimed at revealing the neurobiological sex differences in the same study in acute- and chronically-stressed rats. Female Sprague-Dawley (SD) rats were randomly divided into 6 groups: chronic unpredictable mild stress (CUMS), acute foot shock (FS) and(More)
BACKGROUND Anesthesia administration before sacrificing animals is a common practice in stress-related studies, but the effect of anesthesia on the results remains understudied. We aimed to reveal the interference of different anesthetics, i.e. intraperitoneal (i.p.) sodium-pentobarbital injection or isoflurane inhalation, with the acute stress responses in(More)
BACKGROUND Amino acid neurotransmitters and nitric oxide (NO) are involved in the pathogenesis of major depressive disorder (MDD). Here we want to establish whether changes in their plasma levels may serve as biomarker for the melancholic subtype of this disorder. METHODS Plasma levels of glutamic acid (Glu), aspartic acid (Asp), glycine (Gly),(More)
Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is an autosomal recessive disorder caused by mutations in the CLDN16 or CLDN19 genes, encoding claudin-16 and claudin-19 in the thick ascending limb of Henle’s loop. In patients with claudin-19 mutations, severe ocular involvement (macular coloboma, pigmentary retinitis, nystagmus, or(More)
Nitric oxide (NO) and NO synthase-1 (NOS1) are involved in the stress response and in depression. We compared NOS-NO alterations in rats exposed to chronic unpredictable stress (CUS) with alterations in major depressive disorder (MDD) in humans. In the hypothalamus of male CUS rats we determined NOS activity, and in the paraventricular nucleus (PVN) we(More)
Gonadotropin induces masculinization and spermatogenesis in men with congenital hypogonadotropic hypogonadism (CHH). However, large cohort studies for the efficacy and reliable predictors of this therapy need to be conducted. The aim of this study was to investigate the efficacy of gonadotropin treatment in a large cohort of male CHH patients and analyze(More)
Tea category classification is of vital importance to industrial applications. We developed a tea-category identification system based on machine learning and computer vision with the aim of classifying different tea types automatically and accurately. 75 photos of three categories of tea were obtained with 3-CCD digital camera, they are green, black, and(More)
