Epigastric Pain and Dysphagia in a 36-Year-Old Man Due to Primary Esophageal Small Cell Carcinoma.

BACKGROUND Small cell carcinoma is an aggressive malignant neuroendocrine tumor that most commonly occurs in the lung. Primary small cell carcinoma of the esophagus (PSCCE) is rare and is an aggressive malignancy with poor prognosis and no clear management guidelines. This report describes the case of a 36-year-old man presenting with epigastric pain, dysphagia, and melena due to a primary esophageal small cell carcinoma.

Structural, Functional, and Phylogenetic Analysis of Cytochrome (CYPD) Protein Family.

Cytochrome (CYP) enzymes catalyze the metabolic reactions of endogenous and exogenous compounds. The superfamily of enzymes is found across many organisms, regardless of type, except for plants. Information was gathered about CYP2D enzymes through protein sequences of humans and other organisms.

White Button Mushroom, Agaricus bisporus (Agaricomycetes), and a Probiotics Mixture Supplementation Correct Dyslipidemia without Influencing the Colon Microbiome Profile in Hypercholesterolemic Rats.

Consumption of foods rich in dietary fiber has attracted considerable attention for lowering blood cholesterol and triglycerides through attenuation of gut microbiome. Diets rich in fiber may provide substrates for microbes to digest and proliferate. In response, products of microbial digestion enter systemic circulation and support host energy homeostasis.

REPORT- Some ethanobotanically important plants from Cholistan area for anti avian influenza virus (AIV) H9N2 screening.

Avian influenza or bird flu is a common problem of domestic and wild birds. Some of its strains are able to cross the species barrier and cause infection in various members of class Mammalia. In view of relatively lesser efficacy of vaccines, antiviral therapies remain the only choice for the sustenance of mammals acquiring this highly devastating infection.

Transmitted cardiovascular pulsations on high resolution esophageal impedance manometry, and their significance in dysphagia.

Aim: To investigate the behavior of pulsatile pressure zones (PPZ's) as noted on high resolution esophageal impedance manometry (HREIM), and determine their association with dysphagia.

Methods: Retrospective, single center case control design screening HREIM studies for cases (dysphagia) and controls (no dysphagia). Thoracic radiology studies were reviewed further in cases for (thoracic cardiovascular) thoracic cardiovascular (TCV) structures in esophageal proximity to compare with HREIM findings.

Jackhammer oesophagus in a case of linitis plastica.

A 52-year-old Caucasian woman presented with progressive nausea and vomiting, weight loss, and burning epigastric and chest pain. Initial oesophagogastroduodenoscopy (OGD) with biopsies demonstrated gastritis in absence of Helicobacter pylori A gastric emptying study, CT scan with pancreatic protocol and a colonoscopy revealed no concerning findings. Calcium channel blockers and proton pump inhibitors offered little improvement.

Evaluation of anti-metastatic potential of Cisplatin polymeric nanocarriers on B16F10 melanoma cells.

Nanoparticles are being increasingly used in the field of cancer treatment due to their unique properties and advantages. The aim of the present research work was to prepare and characterize a polymeric albumin nanosystem for Cisplatin and evaluate its in-vitro efficacy against B16F10 melanoma. The developed nanoparticles were almost spherical in shape with a particle size in the range of 150-300 nm, low polydispersity values and about 80% drug entrapment efficiency.
