PDIA3: Structure, functions and its potential role in viral infections.

The catalysis of disulphide (SS) bonds is the most important characteristic of protein disulphide isomerase (PDI) family. Catalysis occurs in the endoplasmic reticulum, which contains many proteins, most of which are secretory in nature and that have at least one s-s bond. Protein disulphide isomerase A3 (PDIA3) is a member of the PDI family that acts as a chaperone.

The Functions of Thioredoxin 1 in Neurodegeneration.

Thioredoxin 1 (Trx1) is a ubiquitous protein that is found in organisms ranging from prokaryotes to eukaryotes. Trx1 acts as reductases in redox regulation and protects proteins from oxidative aggregation and inactivation. Trx1 helps the cells to cope with various environmental stresses and inhibits programmed cell death.

Adenoid cystic carcinoma of external auditory canal: A rare disease.

External auditory canal, like other epithelialized surfaces is predisposed to malignancies such as Squamous cell carcinomas (SCC), melanomas and adenocarcinomas. In this background, malignancies like adenoid cystic carcinoma (ACC) are a rare occurrence and need to be thoroughly evaluated both locally and for distant extension. The malignancy needs to be addressed with an aggressive approach surgically with adequate marginal clearance.

Ecological risk assessment of heavy metal chromium in a contaminated pastureland area in the Central Punjab, Pakistan: soils vs plants vs ruminants.

Grazing animals act as a bioindicator to study the heavy metal status in the pasture lands because excessive amount of toxic metals in the animal diet either disturb their normal activity or deposit the contaminants into their tissues. The aim of this study was to appraise the chromium status in soil and pasture crops with respect to the nutritional requirement of grazing animals. Three different sites were selected to collect soil, forages, and animal samples from District Jhang.

Prevention of Pulmonary Cement Embolism by Inferior Vena Cava Filter following Vertebroplasty-related Cement Intravasation.

A 77 year old woman with recent history of vertebroplasty for treatment of multiple osteoporotic lumbar vertebral body compression fractures presented for post-procedure care. A series of radiographs and cross-sectional imaging of the lumbar spine revealed an unexpected finding of cured bone cement within a small lumbar vertebral vein, the inferior vena cava and within the spokes of an inferior vena cava filter which had originally been placed two years earlier. Inferior vena cava filters have become the standard of care to prevent pulmonary embolism in the setting of deep venous thrombosis.

Postoperative opioid prescribing practices in US adult trauma patients: A systematic review.

Background: Opioids have been proven effective in pain management, but overprescription can lead to addiction and abuse. Although current guidelines regarding opioid prescription for chronic and acute pain are available, they fail to address the use of opioids for pain management in traumatic injury patients who undergo operations. The primary objective of this study was to examine opioid prescribing practices for US adult trauma patients who require surgical management, based on prior history of opioid use, type of surgical practice, and age.
