This contribution explores the historical developments of transnational lesbian, gay, bisexual, transgender, and intersex (LGBTI) psychology in Colombia, the Philippines, Russia, and South Africa in relationship to U.S. LGBT psychology. LGBTI psychology in these diverse contexts share commonalities but also have important variations in their development and focus within LGBTI concerns. The International Psychology Network for Lesbian, Gay, Bisexual, Transgender and Intersex Issues (IPsyNet) provides a model for international professional psychology collaboration and linkage on behalf of advocacy for LGBTI rights and sexual orientation and gender identity and/or expression concerns...

The human infundibular nucleus (corresponding to the rodent arcuate nucleus) serves as an important integration center for neuronal signals and hormones released by peripheral endocrine organs. Kisspeptin (KP)-producing neurons of this anatomical site, many of which also synthesize neurokinin B (NKB), are critically involved in sex hormone signaling to gonadotropin-releasing hormone (GnRH) neurons. In recent years, the basic topography, morphology, neuropeptide content, and connectivity of human KP neurons have been investigated with in situ hybridization and immunohistochemistry on postmortem tissues...

As apoptosis and genome instability in children with autoimmune diseases (AIDs) are insufficiently investigated, we aimed to analyse them in peripheral blood lymphocytes (PBLs) of children and adolescents with Hashimoto's thyroiditis (HT), Graves' disease (GD) and type 1 diabetes mellitus (T1DM), including possible factors that could affect their occurrence. The study population included 24 patients and 19 healthy controls. Apoptotic cells were detected using an Annexin V-FITC/7-AAD kit. Genome instability was measured as micronuclei (MNs) frequency using the cytokinesis-block MN assay...

OBJECTIVES: In vivo evaluations of a gonadotropin releasing hormone-receptor single photon emission computed tomography radiotracer for non-invasive detection of gonadotropin releasing homone-receptors in brain. RESULTS: We have used a simple, robust and high-yielding procedure to radiolabel an alpha-halogenated bioactive compound with high radiochemical yield. Literature findings showed similar alpha-halogenated compounds suitable for in vivo evaluations. The compound was found to possess nano molar affinity for the gonadotropin releasing hormone-receptor in a competition dependent inhibition study...

In this article we stress the need for specifically located understandings of the concept of homonationalism, by introducing an analysis of spatial and political power relations dissecting disparate constructions of LGBT arenas. The article explores three spaces: Tel-Aviv-an urban space of LGBT belonging; Jerusalem-the Israeli capital where being an LGBT individual is problematic both in public and in private spaces; and Kiryat-Shmona-a conservative and peripheral underprivileged town in the north of Israel...

This essay focuses on representations of Russia, the Soviet Union, and Eastern Europe in U.S. homophile periodicals from 1953 to 1964. Extending the application of Jasbir Puar's concept of homonationalism to the Cold War period, the essay examines 128 articles and other items that were published in ONE, Mattachine Review, and The Ladder and demonstrates that these periodicals often engaged in homonationalist discourses when constructing the Russian, Soviet, and Eastern European "other." Negative constructions of these regions were sometimes used to affirm the political alignment of the homophile authors with the American nation...

Pigment aggregation in shrimp chromatophores is triggered by red pigment concentrating hormone (RPCH), a neurosecretory peptide whose plasma membrane receptor may be a G-protein coupled receptor (GPCR). While RPCH binding activates the Ca(2+) /cGMP signaling cascades, a role for cyclic AMP (cAMP) in pigment aggregation is obscure, as are the steps governing Ca(2+) release from the smooth endoplasmic reticulum (SER). A role for the antagonistic neuropeptide, pigment dispersing homone (α-PDH) is also unclear...

Three experiments comparing four estrous synchronization protocols were conducted to determine estrous expression rate and artificial insemination pregnancy rate (AI-PR) in heifers with a range (1-5) of reproductive tract scores (RTSs). At enrollment (Day 0), 1783 Angus cross beef heifers from six locations were given body condition score and RTS. The four protocols were: (1) HRTS-DPGF group-heifers with RTS 5 received prostaglandin F2α (PGF; Dinoprost 25 mg; im) on Days 0 and 14; (2) HRTS-CIDR-PGF group-heifers with RTS 5 received a CIDR (1...

Premature ovarian insufficiency (POI) is defined by the presence of primary or secondary amenorrhea, for at least 4 months, before the age of 40 years associated with follicle stimulating homone levels in menopausal range, exciding 40 UI/L. The diagnosis is confirmed by two blood sample at least 1 month to measure the level of FSH (over 40 UI/L) and level of estradiol (below 50 pmol/L). Ovarian follicular dysfunction and/or depletion of functional primordial follicles characterized this pathology. Abnormal bleeding patterns also include oligomenrrhea and polimenorrhea; because of these irregular menstrual cycles during adolescence, diagnosis could be difficult in young women...

Developmented and introduction into clinical practice of the sciatic nerve blockade as method of guided anesthesia/analgesia for pain syndromes and surgical interventions on the lower legs. Anaesthesia was analyzed in 35 patients. In 15 patients used the blockade of the sciatic nerve bifurcation proposed method with the popliteal fossa in acute and chronic pain syndromes and comparison with spinal anesthesia in 20. Blockade of the sciatic nerve at the site of its bifurcation provides a highly efficient and long-lasting nerve block zones of innervation is sufficient to perform the surgery...

Anesthesiological support of 47 patients, while performing reconstructive operations on the lower extremities arteries in presence of the third level of operative risk (according to ASA), was analyzed; of them in 24 - a spinal anesthesia was applied, in 23 - a reduced spino-epidural anesthesia. Application of a spino-epidural anesthesia/analgesia with reduction of the dose of a spinal component and usage of analgesia instead of anesthesia secures lesser intraoperative oscillations of hemodynamic indices in comparison with such while performing spinal anesthesia, as well as better antinociceptive protection, is also characterized by small toxic impact on the patient, demands application of a sedative and the infusion therapy of lesser volume...

This paper explores arguments for and against same-sex marriage as 'movement advocacy' in the USA as a backdrop to the proposition that, despite the influence of US discourses on South African debates about same-sex marriage, US discussions are less important to understanding South African responses than controversies about marriage itself in the country. The paper works in two sections. First it sketches legal and critical tensions within the USA around the implications of same-sex marriage activism, drawing on work from Franke, Brandzel, Grossman, Puar and others...

Auditory steady-state responses (ASSRs) are widely applied to test brain's ability to follow external stimulation in neuropsychiatric disorders. It is known that ASSRs are related to GABAergic transmission. Female sex steroid homones - both estrogens and progesterone - affect functioning of GABAergic system. However, it is not known how these hormones affect brain's ability to entrain. This study was designed to test the ability to synchronize to 40 Hz stimulation during different phases of the menstrual cycle...

Bone is a dynamic tissue that undergoes renewal and repair throughout life through the process of bone remodelling. Skeletal homeostasis is achieved through coupled and balanced bone resorption and bone formation. Several local and systemic factors regulate these processes, including sex hormones. Estrogenes and androgens influence growth, maturation and maintenance of bone mass. Sex homones act on bone through multiple mechansims. Sex hormones influence synthesis and secretion of many growth factors and cytokines, and play therefore a central role in the regulation of bone metabolism...

Ames dwarf mice, which are small and deficient in growth homone (GH), prolactin (PRL), and thyroid stimulating hormone (TSH) live much longer (1-1.25 years) than their normal siblings. It was of interest to examine the response of these animals to caloric restriction (CR) because of the possibility that dwarf mice are voluntarily caloric restricted. We are testing the hypothesis that this possible natural caloric restriction will negate any benefits of an imposed CR on lifespan. Male and female Ames dwarf mice and their normal counterparts have been fed ad libitum (AL) or a 30% CR diet for 25-29 months...

In most large scale trials the prognosis of ischemic heart failure is worse than in patients with non-ischemic etiology. The therapeutic effect of essential drugs such as ACE-inhibitors, betablockers and diuretics is similar, but response to some other drugs (amiodarone, amlodipine, digoxin, growth homone) is better in non-ischemic heart failure. Of great practical importance is the recognition of hibernating myocardium in coronary artery disease, since revascularisation may significantly improve left ventricular function...

Family and personal history as well as clinical examination are the basic data to be known before laboratory examinations should be started. To obtain results that can be correctly interpreted, the blood sampling has to be done in the early morning hours between day 1 and 5 of the cycle, and for some homones on an empty stomach. Depending on the clinical data, the hormonal screening can be selective and well directed, or it has to be broader. The presence or absence of galactorrhea, of hot flushes and of androgenization or virilization play an important role for the decision about the hormones to be determined...
