This study's objective was to determine if nutrient restriction during late gestation affected beef heifer feed intake, body weight (BW) gain and endocrine regulation during a 10-week feeding trial. During the last 100 days of gestation, control (CON) dams were fed to increase body condition score (BCS). Whereas, nutrient-restricted dams (NR) and NR dams protein supplemented 3 days/week (NRS) were fed to decrease BCS by 1.2. After parturition, all cow-calf pairs were moved to a common pasture and fed in excess of requirements until weaning...

Anti-programmed cell death receptor-1 (PD-1) antibodies represent an effective treatment opinion for advanced melanoma and non-small-cell lung cancer, as well as other cancerous entities. Immune checkpoint inhibitors such as anti-PD-1 antibody result in a unique side-effect profile, commonly described as immune-related adverse events (irAE). These irAE affect the skin, gastrointestinal tract, liver, endocrine system and other organ systems. We report two cases of oral lichenoid reaction showing multiple ulcers associated with nivolumab treatment...

As survival rates have improved owing to advances in management strategies for pediatric brain tumors, long-term complications such as endocrine dysfunction, have emerged as a major issue. This study investigated the long-term endocrine effects of childhood-onset brain tumors in a large number of patients. This study included 151 patients with brain tumors diagnosed between January 1995 and December 2016. The following data were retrospectively reviewed: tumor location, tumor histology, endocrine abnormalities, hypothalamic involvement on brain imaging, treatment modalities, and trends in body mass index...

PURPOSE: Management of breast cancer is a rapidly evolving field, and, although evidence-based guidelines are available for clinicians to provide direction on critical issues in patient care, clinicians often left to address these issues in the context of community practice situations with their patients. These include the patient's comorbid conditions, actual versus perceived benefit of treatments, patient's compliance as well as financial/reimbursement issues, and long-term tolerability of therapy...

BACKGROUND AND AIMS: Abnormal glucagon secretion and functional alterations of the exocrine pancreas have been described in patients with type 1 diabetes (T1D), but their respective anatomical substrata have seldom been investigated. Our aim was to develop an automated morphometric analysis process to characterize the anatomy of α-cell and exocrine pancreas in patients with T1D, using the publicly available slides of the Network for Pancreatic Organ Donors (nPOD). MATERIALS AND METHODS: The ratio of β- and α-cell area to total tissue area were quantified in 75 patients with T1D (thereafter patients) and 66 control subjects (thereafter controls), on 2 insulin-stained and 4 glucagon-stained slides from both the head and the tail of the pancreas...

Advancements in molecular profiling and endocrine therapy (ET) have led to more focused clinical attention on precision medicine. These advances have expanded our understanding of breast cancer (BC) pathogenesis and hold promising implications for the future of therapy. The estrogen receptor-α is a predominant endocrine regulatory protein in the breast and in estrogen-induced BC. Successful targeting of proteins and genes within estrogen receptor (ER) nuclear and nonnuclear pathways remains a clinical goal...

Corticotropin-releasing factor (CRF) neurons in the Paraventricular Nucleus of the Hypothalamus (PVN) initiate Hypothalamic-Pituitary-Adrenal (HPA) axis activity through release of CRF into the portal system as part of a coordinated neuroendocrine, autonomic, and behavioral response to stress. Recent discovery of neurons expressing CRF receptor type 1 (CRFR1), the primary receptor for CRF, adjacent to CRF neurons within the PVN, suggest that CRF also signals within the hypothalamus to coordinate aspects of the stress response...

Multiple endocrine neoplasia (MEN) is a well-known syndrome in human medicine, whereas only a few cases of concurrent endocrine neoplasias have been reported in dogs and cats. The aim of this study was to evaluate the prevalence of concurrent endocrine neoplasias in dogs and cats at our clinic, identify possible breed and sex predispositions and investigate similarities with MEN syndromes in humans. Postmortem reports of 951 dogs and 1155 cats that died or were euthanased at the Clinic for Small Animal Internal Medicine, University of Zurich, between 2004 and 2014 were reviewed, and animals with at least two concurrent endocrine neoplasias and/or hyperplasias were included...

Firemaster 550 (FM 550) is a flame retardant (FR) mixture that has become one of the most commonly used FRs in foam-based furniture and baby products. Human exposure to this commercial mixture, comprised of brominated and organophosphate components, is widespread. We have repeatedly shown that developmental exposure can lead to sex-specific behavioral effects in rats. Accruing evidence of endocrine disruption and potential neurotoxicity have raised concerns regarding the neurodevelopmental effects of FM 550 exposure, but the specific mechanisms of action remains unclear...

Pituitary adenomas account for the top three primary intracranial tumors in terms of total incidence rates. The clinical symptoms presented by the disease are often characterized by a series of systemic endocrine disorders, severe occupational lesions, and even some malignant features, and therefore early diagnosis and predicting recurrence would be instructive for clinical treatment of pituitary adenomas. An increasing number of specific microRNA (miRNA) expression signatures have been identified in pituitary, and miRNAs are related with the pituitary tumorigenesis, dysfunction, neurodegeneration, and metastatic non-functioning pituitary carcinoma...

The transcription factors Pdx1 and Oc1 are co-expressed in multipotent pancreatic progenitors (MPCs), but their expression patterns diverge in hormone-expressing cells, with Oc1 expression being extinguished in the endocrine lineage and Pdx1 being maintained at high levels in β cells. We previously demonstrated that cooperative function of these two factors in MPCs is necessary for proper specification and differentiation of pancreatic endocrine cells. In those studies, we observed a persistent decrease in expression of the β-cell maturity factor MafA...

The 24h responses to small-sided games (SSG) soccer training were characterized. Professional soccer players (n=16) performed SSG's (4vs4 + goalkeepers; 6x7-min, 2-min inter-set recovery) with performance (peak-power output, PPO; jump height, JH), physiological (blood creatine kinase: CK, lactate; salivary testosterone, cortisol), and mood measures collected before (baseline), and after (immediately; 0h, +2h, +24h). For PPO and JH, possibly small-moderate reductions occurred at 0h (-1.1W·kg; ±0.9W·kg, -3...

Papillary thyroid carcinomas are the most common endocrine cancer and are usually associated with good survival. However, some variants of papillary thyroid carcinomas may behave more aggressively than classic papillary thyroid carcinomas. The tall cell variant of papillary thyroid carcinoma is the most common aggressive variant of papillary thyroid carcinoma. The aggressive behavior has been ascribed to the histologic subtype and/or to the clinicopathologic features, an issue that remains controversial. The columnar variant of papillary thyroid carcinoma can be aggressive, particularly in older patients, with larger tumors showing a diffusely infiltrative growth pattern and extrathyroidal extension...

Hypoparathyroidism (HPT) is a rare disease with leading symptoms of hypocalcemia, associated with high serum phosphorus levels and absent or inappropriately low levels of parathyroid hormone (PTH). In patients with thalassemias it is mainly attributed to transfusional iron overload, and suboptimal iron chelation therapy. The main objectives of this survey were to provide data on the prevalence, demographic and clinical features of HPT in thalassemia major (TM) and intermedia (TI) patients living in different countries, and to assess its impact in clinical medical practice...

The effect of treatment with combined butylparaben and triclosan on male gonadal toxicity in weanling rats was investigated. All treated groups experienced atrophy in the ventral prostate and seminal vesicle, likewise significant depletion in the number and motility of sperm. Given individually or combined butylparaben and triclosan, significantly decreased testosterone, luteinizing hormone, and follicle-stimulating hormone levels. Individual treatment with tested compounds caused significant elevation in the E2 level, whereas combined treatment did not alter the E2 level...

Fish early life stage (FELS) tests (OECD test guideline 210) are widely conducted to estimate chronic fish toxicity. In these tests, fish are exposed from the embryonic to the juvenile life stage. In order to analyse whether certain modes of action are related to high toxic ratios (TR, i.e., ratios between experimental effect and baseline toxicity) and/or acute-to-chronic ratios (ACR) in the FELS test effect concentrations for 183 compounds were extracted from the US EPA ecotoxicity database. Analysis of effect concentration of narcotic compounds indicated that baseline toxicity could be observed in the FELS test at similar concentrations as in acute fish toxicity test...

Epidemiological studies have provided evidence that traffic noise exposure is linked to cardiovascular diseases such as arterial hypertension, myocardial infarction and stroke. Noise is a non-specific stressor that activates the autonomous nervous system and endocrine signaling. According to the noise reaction model introduced by Babisch and colleagues, chronic low levels of noise can cause so called non-auditory effects, such as disturbances of activity, sleep and communication, which can trigger a number of emotional responses, including annoyance and subsequent stress...

A majority of breast cancers are hormone receptor (HR) positive and are responsive to various types of hormone manipulation. Endocrine therapy is the preferred first-line therapy for patients with advanced estrogen receptor (ER) positive, HER2-negative breast cancer who do not have symptomatic visceral disease. Endocrine therapy is often continued in the second- and third-line setting, with chemotherapy deferred until tumor becomes endocrine therapy refractory and/or a visceral crisis in imminent. Therapeutic options vary based on clinical presentation and include single-agent therapies such as tamoxifen, aromatase inhibitors and fulvestrant, and combination therapies options...
