Prostaglandins (PGs) are the key mediators of several female reproductive functions, including luteolysis, ovulation, fertilization, implantation, pregnancy, and parturition. The present study was conducted in buffalo endometrial and luteal tissues between nonpregnant and two stages of pregnancy (29-38 days of pregnancy, 48-56 days of pregnancy) tissue samples. The genes involved from synthesis upto receptor level effect of PGs (PGF2α and PGE2) were studied for their relative mRNA expression. We have collected the endometrial and luteal tissues from slaughtered animals and confirmed the stages by external examination and crown vertebral rump length measurement of the foetus...

BACKGROUND: While, at its inception in 1993, the health care system in Colombia was publicized as a paradigm to be copied across the developing world, numerous problems in its implementation have led to, what is now, an inefficient and crisis-ridden health system. Furthermore, as a result of inappropriate tools to measure the quality of the health service providers, several corruption scandals have arisen in the country. This study attempts to tackle this situation by proposing a strategy for the quality assessment of the health service providers (Entidades Promotoras de Salud, EPS) in the Colombian health system...

DNA fragmentation factor 40 (DFF40) is a key executor of apoptosis. It localizes to the nucleus together with DNA fragmentation factor 45 (DFF45), which acts as a DFF40 inhibitor and chaperone. B-cell lymphoma (Bcl-2) protein is a proven antiapoptotic factor present in the cytoplasm. In this study, we aimed to investigate DFF40, DFF45, and Bcl-2 immunoexpression in endometrial polyps (EPs) and benign endometrial hyperplasia (BEH) tissue compared with that in normal proliferative endometrium (NPE) and normal secretory endometrium (NSE) as well as normal post menopausal endometrium (NAE)...

BACKGROUND: Tiludronic acid (TIL) presents antiresorptive and anti-inflammatory properties and it has not been evaluated in the association periodontitis-diabetes mellitus (DM) to date. This study evaluated the effects of local administration of TIL on experimental periodontitis (EP) in rats with streptozotocin-induced DM. METHODS: Thirty-two animals (Rattus norvegicus, albinus, Wistar) were divided into groups DM/C (Control), DM/EP, DM/EP/TIL1 and DM/EP/TIL3. In groups EP, a ligature was placed around mandibular molars (MM)...

Warfarin is intensively discussed drug with narrow therapeutic range. There have been cases of bleeding attributed to varying content or altered quality of the active substance. Factor analysis is useful for finding suitable technological parameters leading to high content uniformity of tablets containing low amount of active substance. The composition of tabletting blend and technological procedure were set with respect to factor analysis of previously published results. The correctness of set parameters was checked by manufacturing and evaluation of tablets containing 1-10mg of warfarin sodium...

Exposure to low concentrations of heavy metals and metalloids represents a well-documented risk to animal and human health. However, current standards (European Pharmacopeia [EP], United States Pharmacopoeia [USP], International Organization for Standardization [ISO], YBB concerned with rubber closures) only require testing for Zn in pharmaceutical-grade rubber stoppers and then using only pure water as a solvent. We extracted and quantified heavy metals and trace elements from pharmaceutical-grade rubber stoppers under conditions that might occur during the preparation of drugs...

Enzootic pneumonia (EP) in pigs caused by Mycoplasma (M.) hyopneumoniae has successfully been combatted in Switzerland. A control program was fully implemented in 2004 which is based on total depopulation strategies of affected fattening farms as well as partial depopulation on breeding farms. Thereby, the number of cases has dropped drastically from more than 200 in 2003 to two cases in 2013. Currently monitoring is done based on clinical observation and subsequent diagnostic of coughing pigs. Moreover, in case of more than 10% gross pathological lesions per slaughter batch laboratory confirmation for EP is compulsory...

One-electron oxidation of the rhodium(I) azido complex [Rh(N3)(PNP)] (5), bearing the neutral PNP ligand 2,6-bis(di-tert-butylphosphinomethyl)pyridine leads to instantaneous and selective formation of the mononuclear rhodium(I) dinitrogen complex [Rh(N2)(PNP)]+ (9+). Interestingly, complex 5 also acts as a catalyst for electrochemical N3- oxidation in the presence of excess azide at a substantially lower potential (Ep ~ -0.23 V vs. Fc+/0) than direct oxidation at Pt-electrodes (Ep ~ +0.19 V vs. Fc+/0). Cyclic voltammetry in the presence of an excess of N(nBu)4N3 reveals that electro-catalytic N3-oxidation occurs at roughly the same potential as the first oxidation wave of 5...

BACKGROUND: The development of acute pancreatitis (AP) is associated with intracellular events in pancreatic cells, as well as with early and late inflammatory responses; however, their underlying mechanisms remain unclear. This study investigated trypsinogen activation peptide (TAP)-induced release of high mobility group box-l (HMGB1) from pancreatic acinar cells and how ethyl pyruvate (EP) affects this release. METHODOLOGY: Pancreatic acinar cells from Sprague Dawley rats were divided into control, TAP (administered TAP), and EP (administered TAP and EP) groups...

Obstructive sleep apnea (OSA) is accompanied by altered structure and function in cortical, limbic, brainstem, and cerebellar regions. The midbrain is relatively unexamined, but contains many integrative nuclei which mediate physiological functions that are disrupted in OSA. We therefore assessed the chemistry of the midbrain in OSA in this exploratory study. We used a recently-developed accelerated 2D magnetic resonance spectroscopy (2D-MRS) technique, compressed sensing-based 4D echo-planar J-resolved spectroscopic imaging (4D-EP-JRESI), to measure metabolites in the midbrain of 14 OSA (mean age±SD:54...

BACKGROUND: The CD44 receptor is a cell surface glycoprotein, which mediates many physiological and pathological activities. Its key role is to provide defence against inflammatory reactions by cellular transmigration and cell signalling. In pathological conditions, it gives destructive outcomes by mediating migration of pathogenic cells to vital organs resulting in tissue and organ damage. It binds to several ligands principally the hyaluronan. OBJECTIVE: This review explores CD44 structure, functions, and its potential as a disease indicator and therapeutic target...

PURPOSE: To compare the concordance in risk classification between the EndoPredict and the MammaPrint scores obtained for the same cancer samples on 40 estrogen-receptor positive/HER2-negative breast carcinomas. METHODS: Formalin-fixed, paraffin-embedded invasive breast carcinoma tissues that were previously analyzed with MammaPrint as part of routine care of the patients, and were classified as high-risk (20 patients) and low-risk (20 patients), were selected to be analyzed by the EndoPredict assay, a second generation gene expression test that combines expression of 8 genes (EP score) with two clinicopathological variables (tumor size and nodal status, EPclin score)...

The treatment of esophageal perforation (EP) remains a significant clinical challenge. While a number of investigators have previously documented efficient approaches, these were mostly single-center experiences reported prior to the introduction of newer technologies: specifically endoluminal stents. This study was designed to document contemporary practice in the diagnosis and management of EP at multiple institutions around the world and includes early clinical outcomes. A five-year (2009-2013) multicenter retrospective review of management and outcomes for patients with thoracic or abdominal esophageal perforation was conducted...

A new classification of magnifying endoscopy with narrow band imaging (ME-NBI) for diagnosing and staging superficial esophageal squamous cell carcinoma (SESCC) was proposed by the Japan Esophageal Society in 2011. This study aimed to compare the new classification with the conventional classifications (Inoue's classification and Arima's classification). This was a prospective analysis of data from a single cancer center involving 151 consecutive patients with 156 SESCCs that were endoscopically or surgically resected...

An effective scheme on switching the exceptional point(EP) where unidirectional reflectionlessness occurs is firstly proposed in non-ideal PT metamaterial via the polarization of incident light. The unidirectional reflectionlessness could be effectively controlled only by adjusting the phase coupling of the two resonators which are consisted of two identical but vertically placed crosses and are excited by incident light as an effective gain. Besides, the unidirectional perfect absorber occurs in the vicinity of EP...

PURPOSE: Interleukin (IL)-25 and IL-33 induce IL-5 production by various types of cells, such as type 2 helper T (Th2) cells and type 2 innate lymphoid cells. The number of Th2 cells and concentration of IL-5 in the bronchoalveolar lavage fluid (BALF) are increased in patients with eosinophilic pneumonia (EP). To examine the contribution of IL-25 and IL-33 to eosinophilic inflammation of the lung in humans, we evaluated IL-5, IL-25 and IL-33 levels in the BALF of patients with EP. METHODS: IL-5, IL-25, and IL-33 concentrations in the BALF were measured by enzyme-linked immunosorbent assay in patients with acute eosinophilic pneumonia (AEP), chronic eosinophilic pneumonia (CEP), idiopathic pulmonary fibrosis (IPF), and sarcoidosis...

INTRODUCTION: Hospital admissions from the emergency department (ED) now account for approximately 50% of all admissions. Some patients admitted from the ED may not require inpatient care if outpatient care could be optimized. However, access to primary care especially immediately after ED discharge is challenging. Studies have not addressed the extent to which hospital admissions from the ED may be averted with access to rapid (next business day) primary care follow-up. We evaluated the impact of an ED-to-rapid-primary-care protocol on avoidance of hospitalizations in a large, urban medical center...

INTRODUCTION: Transesophageal echocardiography (TEE) is a well-established method of evaluating cardiac pathology. It has many advantages over transthoracic echocardiography (TTE), including the ability to image the heart during active cardiopulmonary resuscitation. This prospective simulation study aims to evaluate the ability of emergency medicine (EM) residents to learn TEE image acquisition techniques and demonstrate those techniques to identify common pathologic causes of cardiac arrest...
