LP533401 is an orally bioavailable small molecule that inhibits tryptophan hydroxylase-1, an enzyme responsible for the synthesis of gut-derived serotonin (GDS). Recently, we showed that increased GDS in rats with chronic kidney disease (CKD) affected bone strength and metabolism. We tested the hypothesis that treatment with LP533401 could reverse CKD-induced bone loss in uremia. Sixteen weeks after 5/6 nephrectomy, rats were randomized into untreated (CKD), treated with vehicle (VEH) and LP533401 at a dose of 30 or 100 mg/kg daily for 8 weeks...

Context: In healthy adults with detectable cold-induced brown fat activation (CIBA), the relationships between sympathetic nervous system (SNS) or thyroid activity during energy balance (EBL) with CIBA and body composition change are undetermined. Objective: To investigate the relationships between CIBA and thermoneutral catecholamines and thyroid hormones measured during EBL and to determine if CIBA, catecholamines, or thyroid hormones predict body composition changes...

A 31-year-old patient was followed for cystinuria, justifying CT scans. In 2006, a tissue mass of 3cm of the right adrenal gland, homogeneous, measured at 3.5cm in 2007 was noted. Blood pressure was 90/61mmHg, without orthostatic hypotension. During the clinical interview, no discomfort, sweat attack, headache, or palpitation was reported by the patient. Hormonal assays did not favor a primary hyperaldosteronism, or a hypercortisolism. Adrenal androgens were normal. 24h normetanephrines urinary excretion and metanephrines to creatinine ratio were elevated...

CONTEXT: Hypothyroidism is a significant cause of pericardial effusion. However, large pericardial effusions due to hypothyroidism are extremely rare. Hormone replacement therapy is the cornerstone of treatment for hypothyroidism and regular follow-up of patients after initiation of the therapy is indicated. Herein, the case of a 70-year-old woman with a massive pericardial effusion due to Hashimoto's disease is presented. ISSUES: A 70-year-old female from a rural village on the island of Crete, Greece, was admitted to our hospital due to a urinary tract infection...

OBJECTIVE: To test the hypothesis that risk factors for BPS/IC in women differ between those with and without the BPS/IC prodrome. METHODS: Incident cases of BPS/IC and healthy controls were recruited nationally. More than half the BPS/IC cases reported subsyndromal urinary symptoms for decades before onset of BPS/IC and were identified as having the prodrome. Risk factors for BPS/IC were examined separately for cases with and without the prodrome using a set of matched controls...

A 74-year old man presented to us with difficulty urinating. The laboratory examinations revealed an elevated prostate-specific antigen (PSA) level. A prostate biopsy revealed prostate adenocarcinoma. The computed tomography scan showed metastasis to lymph nodes in the pelvic cavity and both adrenal glands. Combined androgen blockade therapy was started, and PSA levels began to decrease gradually. However, 2 months later, he was hospitalized for treatment of cellulitis and was found to have hypertension, hyperglycemia, and hypokalemia...

The underlying cause of stress urinary incontinence (SUI) is an anatomical abnormality associated with paraurethral connective tissue dysfunction. The question as to whether estrogens affect the quality of that tissue remains unexplained. Samples of paraurethral connective tissue from 81 women were examined (the SUI's n = 49; the control's n = 32). In both groups, the patients were subdivided into pre- and postmenopausals. Primary study outcome was comparison of the estrogen receptor alpha (ERα) and the estrogen receptor beta (ERβ) gene and protein in paraurethral tissue between SUI and control group...

OBJECTIVE: To identify prognostic factors associated with a low-iodine diet (LID) and the amount of remnant thyroid tissue in Japanese patients with differentiated thyroid cancer (DTC) who received initial I-131 remnant ablation (RAI) using a fixed low dose of I-131 (1110 MBq). PATIENTS AND METHODS: In this prospective study, we enrolled 45 patients. Patients were classified into a self-managed LID group and a strict LID group. We measured the urinary iodine concentration on the day of RAI after patients consumed LID for 2 weeks...

As a major phytoestrogen of soy, genistein effectively prevents bone loss in both humans and rat models of osteoporosis. However, although the bone-sparing effects of genistein are achieved directly through estrogen receptors, its mode of action on bone by modulation of other endocrine functions is not entirely clear. Thus, thyroid hormones and calcitonin (CT) have an essential influence on bone metabolism. Besides its action on bones, in this study we examined the effect of genistein on the activity of two different endocrine cell populations, thyroid follicular and C-cells...

Urine contains extracellular vesicles (EVs) that concentrate molecules and protect them from degradation. Thus, isolation and characterisation of urinary EVs could increase the efficiency of biomarker discovery. We have previously identified proteins and RNAs with differential abundance in urinary EVs from prostate cancer (PCa) patients compared to benign prostate hyperplasia (BPH). Here, we focused on the analysis of the metabolites contained in urinary EVs collected from patients with PCa and BPH. Targeted metabolomics analysis of EVs was performed by ultra-high-performance liquid chromatography-mass spectrometry...

REVIEW
Toni E Ziegler
Studying the neural and hormonal changes that modulate behavior is critical to understanding social relationships. Of particular interest is measuring oxytocin (OT) and arginine vasopressin (AVP) peripherally, and preferably, non-invasively, in nonhuman primates. Due to these peptides' neural origin and their stimulation of brain areas that influence social behavior, there has been debate whether peripheral measures in blood, urine, and saliva reflect central levels in the brain. This review elucidates the challenges of OT measurement and the solutions that provide valuable data on OT's role in social behavior...

Infant handling describes interactions between infants and non-maternal group members and is widespread across mammalian taxa. The expression of infant handling behaviors, defined as any affiliative or agonistic interaction between a group member and an infant, varies considerably among primate species. Several functional hypotheses may explain the adaptive value of infant handling including the Kin Selection hypothesis, which describes handling as a mechanism through which indirect fitness is increased and predicts a bias in handling behaviors directed toward related (genetic) infants; the Alliance Formation hypothesis, which describes handling as a social commodity and predicts females with infants will support handlers during conflict; and the Learning-to-Mother hypothesis, which describes handling as a mechanism through which handlers learn species-specific maternal behaviors and predicts that handling will occur most frequently in immature and nulliparous females...

Several experimental studies have shown that fibroblast growth factor 23 (FGF23) induces left ventricular hypertrophy (LVH). However, the opposite directional relationship, namely a potential effect of LVH on FGF23, remains uncertain. Here we evaluated the effects of LVH on FGF23 using cardiomyocyte-specific calcineurin A transgenic mice. At six weeks, these mice showed severe LVH, with elevated levels of serum intact FGF23. FGF23 levels were elevated in cardiomyocytes, but not osteocytes, of the transgenic animals...

PURPOSE: Previous studies on adrenal incidentalomas (AIs) are limited by their retrospective design, small numbers of patients, Western populations, or use of an outdated imaging technique. We investigated the characteristics of AIs in Korean patients and compared them with those reported in the largest retrospective study in Italy to discover the effects of improved imaging techniques and ethnicity differences. MATERIALS AND METHODS: This was a prospective, multicenter, cross-sectional observational study including 1005 Korean patients...

The poor captive breeding success of southern hairy-nosed wombats (SHNWs; Lasiorhinus latifrons) has been attributed to the difficulty in accurately characterising oestrous behaviour and their relationship to circulating reproductive hormones. Over two wombat breeding seasons, the use of infrared cameras for 24-h remote behavioural monitoring and the analysis of urine samples collected from seven captive females, were investigated to determine the relationship between behaviour and changes in urinary progesterone metabolites (P4M)...

BACKGROUND: Iodine is an important element for the thyroid hormone production, and its deficiency or excessive intake is associated with various thyroid diseases. Little is known about the association between iodine status and thyroid function among children and adolescents living in iodine-rich areas, therefore, we analyzed this association using data from a nationwide survey. METHODS: From the Korea National Health and Nutrition Examination Surveys (KNHANES) VI (2013-2015) data, 1288 subjects (711 male) aged 6-19 years who underwent urinary iodine concentration (UIC) test and 1000 subjects (564 male) aged 10-19 years who underwent thyroid function test were included in this study...

An increasing number of studies have revealed that phthalate exposure alters thyroid hormone homeostasis in the general population, but there is insufficient evidence of the effect of longitudinal maternal phthalate exposure on maternal and fetal thyroid hormones during pregnancy. We longitudinally assessed the effect of prenatal phthalate exposure in pregnant women on umbilical cord and maternal thyroid hormones at three trimesters during pregnancy. We recruited 98 pregnant women and collected urine and blood samples at three trimesters in an obstetrics clinic in Southern Taiwan from 2013 to 2014...
