Twelve tips for peer teaching by a medical education student society.

University societies are student-led organisations which provide excellent opportunities for students to collaborate in a shared interest. Peer teaching is gaining recognition as an effective method of medical education. Peer teaching also provides student tutors with core educational skills and provides students with approachable peer mentors.

Exchange Interactions and Magnetic Properties of a Molecular Mn -Ring Complex.

[Mn O(OAc) (HOAc)]  ⋅ x AcOH (x=6-9) represents a rare example of a compound containing molecular Mn -rings. These are formed by Mn (μ -O) subunits in which the high-spin Mn(III) centers are bridged by three pairs of acetate anions (AcO ). An AcOH molecule coordinates to one of the Mn atoms leading to [Mn (μ -O)(μ -OAc) (AcOH)]-units, designated in short as Mn -units, that are interconnected by acetate anions via the other two Mn atoms to form Mn -rings.

Thrombin Signaling Contributes to High Glucose-Induced Injury of Human Brain Microvascular Endothelial Cells.

Background: Diabetes is one of the strongest disease-related risk factors for Alzheimer's disease (AD). In diabetics, hyperglycemia-induced microvascular complications are the major cause of end-organ injury, contributing to morbidity and mortality. Microvascular pathology is also an important and early feature of AD.

Ultrasound Guided Laparoscopic Port Placement in a Patient with Congenital Anomaly of IVC Undergoing Sleeve Gastrectomy.

We report a patient with obesity who underwent laparoscopic sleeve gastrectomy after pre-operative ultrasound mark up to enable safe port insertion due to presence of venous collaterals in the abdominal wall as a result of congenial IVC anomaly. This patient was falsely presumed to have NASH cirrhosis. Detailed preoperative workup ruled this out and led to the discovery of congenital IVC anomaly as the cause of engorged blood vessels in the anterior abdominal wall.

The Impact of Laparoscopic Gastric Bypass on Comorbidities and Quality of Life in the Older Obese Patients (Age > 60): Our UK Experience.

Background: With population ageing, more older patients would benefit from the reduced comorbidities associated with laparoscopic Roux-en-Y gastric bypass (LRYGB). However, health care providers are still reluctant to offer bariatric surgery to older obese patients due to the perceived increased risk and possible reduced benefit. Here, we report the outcomes of first UK series of LRYGB in patients (> 60 years) with emphasis on quality of life (QoL).

Factors Predicting Length of Stay Following Bariatric Surgery: Retrospective Review of a Single UK Tertiary Centre Experience.

Background: Laparoscopic Roux Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) are the most commonly performed bariatric procedures. Improvement in techniques and perioperative management of patients have resulted in shorter hospital stay and reduced overall costs. Many post-operative protocols aspire to post-operative day 1 discharge with studies showing reduction in length of stay without increasing complications.

Refinement of the X-linked nonsyndromic high-grade myopia locus MYP1 on Xq28 and exclusion of 13 known positional candidate genes by direct sequencing.

Purpose: Myopia is a common vision problem affecting almost one third of the world's population. It can occur as an isolated genetic condition or be associated with other anomalies and/or syndromes. Seventeen myopia loci have been identified on various chromosomes; however, no specific gene mutations have yet been identified.

Common extensor origin release in recalcitrant lateral epicondylitis - role justified?

The aim of our study was to analyse the efficacy of operative management in recalcitrant lateral epicondylitis of elbow. Forty patients included in this study were referred by general practitioners with a diagnosis of tennis elbow to the orthopaedic department at a district general hospital over a five year period. All had two or more steroid injections at the tender spot, without permanent relief of pain.

Surgery is associated with lower morbidity and longer survival in elderly breast cancer patients over 80.

As breast cancer is the most frequent cancer in the elderly with a peak incidence of 1 in 10 by the age of 80, it is important to establish optimum therapy in this group. We conducted a case note-based retrospective study of all elderly primary breast cancer patients aged 80 and above between 1992 and 2002. The type of treatment, complications, disease progression, recurrence, and overall survival were recorded.

Management of early breast cancer in the elderly.

Breast cancer is the most common malignancy in women with an age related increase in incidence ranging from 1 in 50 at age 50 to 1 in 10 at age 80. This is particularly significant in view of the changing demographics in the western population, characterised by an aging population and increased life expectancy. However in spite of favourable prognostic factors and less aggressive biological behaviour, elderly breast cancer patients receive less aggressive treatment when compared with their younger counterparts.

An efficient one-pot synthesis of polyhydroquinolines at room temperature using HY-zeolite.

An efficient one-pot synthesis of polyhydroquinolines by four-component coupling reactions of aldehydes, ethyl acetoacetate, dimedone and ammonium acetate in the presence of HY-zeolite at ambient temperature has been achieved. The conversions took shorter times to form the products in excellent yields. HY-zeolite can be recovered and reused.

Development and validation of a liquid chromatographic method for monitoring of process-related synthetic organic impurities of profenofos in technical products.

A simple and rapid reversed-phase high-performance liquid chromatographic method for the monitoring of process-related synthetic organic impurities of profenofos (PFS) is developed. Impurities are separated and determined on a reversed-phase Hypersil C(18) column using gradient elution of 50 mM ammonium formate buffer-acetonitrile as a mobile phase and detection at 230 nm at ambient temperature. The method is validated with respect to accuracy, precision, linearity, and limits of detection and quantitation.

Heavy metals in the SPM of air in the environment surrounding a ferro-alloy industrial plant in India.

Prices for ferro-alloys have hardened due to the closure of plants in developed countries on account of increasingly stringent pollution control legislation, resulting in a higher cost of production. A ferro-alloy industry with a capacity of 80000 MT per annum was selected to study the nature of pollution. Because of the objectionable nature of polluting air in and around the plant it was located in a rural area where there was no other industry.
