Micro-RNAs miR-375-3p and miR-7-5p are released alongside ACTH from corticotroph pituitary neuroendocrine tumor

2021

AbstractObjectiveCirculating miRNAs are found in bodily fluids including plasma and can serve as biomarkers for diseases. The aim of this study was to provide the first insight into the landscape of circulating miRNAs in close proximity to the adrenocorticotropic hormone (ACTH) secreting PitNET. To achieve this objective next-generation sequencing of miRNAs in plasma from bilateral inferior petrosal sinus sampling (BIPSS) - a gold standard in diagnosing ACTH-secreting PitNETs, was carried out.MethodsSinistral (left) and dextral (right) BIPSS blood samples of the patient were collected in three time points: before the administration of corticotropin-releasing hormone, 5 and 15 minutes after …

Gonadotropin-releasing hormone analogues for palliation of carcinoma of the prostate

1983

Since the introduction of contrasexual treatment as the basic concept of palliation of prostatic carcinoma in the 1940's, orchiectomy, estrogens, and, in recent years, antiandrogens have become generally accepted treatment forms. Three facts: 1) estrogen treatment being at best palliative and at worst dangerous; 2) surgical castration having psychological impacts, at least in the younger age group; and 3) both being probably ineffective from the beginning, have led us to investigate an alternative of minimal toxicity and possible reversibility in the initial treatment of advanced prostatic carcinoma. 12 patients with far advanced carcinoma of the prostate were treated with the gonadotropin …

The impact of grouping patients by the 2017 GOLD COPD strategy on response to therapy: post hoc results from the TONADO tiotropium+olodaterol trials

2017

Introduction: In the 2017 GOLD COPD strategy the classification of patients by assessment of symptoms and history of exacerbation is used to guide treatment choices. The previous strategy also included lung function. Aims and objectives: To investigate the effect of the 2017 classification on an analysis of the efficacy of tiotropium+olodaterol (T+O) in GOLD stage A/B patients with COPD. Methods: Patients from the Phase III, replicate 52-week TONADO studies (NCT01431274, NCT01431287), who received T+O or the mono-components, were classed as GOLD A/B or C/D by the 2017 strategy (using exacerbation history) or 2014 strategy (using lung function and exacerbation history). Since mMRC Dyspnoea S…

Increased Connexin 43 Expression as a Potential Mediator of the Neuroprotective Activity of the Corticotropin-Releasing Hormone

2009

CRH is a major central stress mediator, but also a potent neuroprotective effector. The mechanisms by which CRH mediates its neuroprotective actions are largely unknown. Here, we describe that the gap junction molecule connexin43 (Cx43) mediates neuroprotective effects of CRH toward experimentally induced oxidative stress. An enhanced gap junction communication has been reported to contribute to neuroprotection after neurotoxic insults. We show that CRH treatment up-regulates Cx43 expression and gap junctional communication in a CRH receptor-dependent manner in IMR32 neuroblastoma cells, primary astrocytes, and organotypic hippocampal slice cultures. MAPKs and protein kinase A-cAMP response…

Controlled Ovarian Stimulation Induces a Functional Genomic Delay of the Endometrium with Potential Clinical Implications

2008

Context: Controlled ovarian stimulation induces morphological, biochemical, and functional genomic modifications of the human endometrium during the window of implantation. Objective: Our objective was to compare the gene expression profile of the human endometrium in natural vs. controlled ovarian stimulation cycles throughout the early-mid secretory transition using microarray technology. Method: Microarray data from 49 endometrial biopsies obtained from LH+1 to LH+9 (n = 25) in natural cycles and from human chorionic gonadotropin (hCG) +1 to hCG+9 in controlled ovarian stimulation cycles (n = 24) were analyzed using different methods, such as clustering, profiling of biological processes…

Thyrotropin Receptor Blocking Antibodies.

2018

AbstractAutoantibodies (Ab) against the thyroid-stimulating hormone receptor (TSHR) are frequently found in autoimmune thyroid disease (AITD). Autoantibodies to the TSHR (anti-TSHR-Ab) may mimic or block the action of TSH or be functionally neutral. Measurement of anti-TSHR-Ab can be done either via competitive-binding immunoassays or with functional cell-based bioassays. Antibody-binding assays do not assess anti-TSHR-Ab functionality, but rather measure the concentration of total anti-TSHR binding activity. In contrast, functional cell-based bioassays indicate whether anti-TSHR-Ab have stimulatory or blocking activity. Historically bioassays for anti-TSHR-Ab were research tools and were u…

Safety and efficacy of exercise testing with atropine in patients with recent uncomplicated ST elevation acute myocardial infarction

2012

Background: Exercise testing (ET) remains the most accessible and widely used technique for the detection of coronary artery disease (CAD) and for the assessment of its severity. Failure to reach 85% of maximal predicted heart rate (MPHR) during exercise may render an ET nondiagnostic for ischemia detection in patients with recent uncomplicated ST elevation acute myocardial infarction (STEMI). We sought to investigate the injection of atropine in patients who fail to achieve 85% of age-predicted heart rate during ET, defining its safety and efficacy to raise heart rate to adequate levels as well as to determine its effect on ET interpretation. Methods: Between January 2005 and December 2008…

Anterior chamber depth measurement in teenagers. Comparison of two techniques

2013

Purpose: The aim of this study is to determine the anterior chamber depth (ACD) in teenagers using two different devices: partial coherence interferometry IOLMaster (Carl Zeiss Meditec) and anterior segment optical coherence tomography (Visante TM OCT, Carl Zeiss Meditec) and to evaluate the degree of agreement between ACD measurements carried out by both instruments. Methods: In this prospective study 68 eyes of 34 emmetropic Caucasic patients (18 girls and 16 boys) were analysed. ACD was measured from the anterior corneal surface to anterior surface of the crystalline lens. For each age the ACD size was calculated and the difference between IOLMaster and Visante-OCT measurements was analy…

Health and Demographic Characteristics of Patients Attending a Newly-Opened Medical Facility in a Remote Amazonian Community: A Descriptive Study

2018

Peru is a country with wide regional disparities in health. Remote Amazonian communities have high rates of poverty and poor access to health services. There is a lack of data on morbidity and use of health services in the region. We describe a descriptive, cross-sectional study of the demographic characteristics and presenting complaints of attendees to a newly-opened primary care facility in a remote community. This was supplemented by structured interviews of adult attendees to build a picture of sociocultural determinants of health locally, including engagement with traditional forms of medicine. Our study provides novel insights into an under-studied and under-resourced area. We found …
