Colorimetric aptasensor for on-site detection of oxytetracycline antibiotic in milk.

Oxytetracycline (OTC), one of the largely used antibiotic in veterinary practice has been banned due to its potential side effects. Development of a field applicable and affordable kit to detect OTC will help to eliminate such milk from human consumption. An aptamer has been designed (27 nt; K = 29.

A Rare Case of Mitral Valve Prolapse in Endomyocardial Fibrosis.

Mitral valve prolapse in endomyocardial fibrosis (EMF) is an unusual entity. Literature search reveals only 1 report of mitral valve prolapse assosiated with EMF. A 32-year-old woman, of African origin, who presented with features of right heart failure, was diagnosed to have mitral valve prolapse of rheumatic origin with severe mitral regurgitation and severe pulmonary hypertension (PAH).

Multiple pilomatrixomas: case report and literature review.

Morphological changes during growth in healed childhood spinal tuberculosis: a 15-year prospective study of 61 children treated with ambulatory chemotherapy.

Study Design: A retrospective clinical study for prognostic purposes.

Objective: To study the morphological changes that dictate the variable progression of childhood spinal tuberculosis.

Summary Of Background Data: Posttuberculous kyphosis in children either improves or deteriorates during growth.

Preemptive analgesia for postoperative pain relief in lumbosacral spine surgeries: a randomized controlled trial.

Background Context: Administration of analgesic medication, before the actual onset of painful stimulus, is more effective than that after the onset of painful stimulus. This is the principle of preemptive analgesia. Although it is often considered superior to other forms of analgesia, its role in postoperative pain relief after lumbosacral spinal surgery has not been fully investigated.
