Abstract: The etiology of pre-harvest deterioration of Soursop (Annona muricata) fruit in Ibadan, southwestern Nigeria and the effects on its nutrient composition was investigated. Four fungal pathogens including Botryodiplodia theobromae, Fusarium sp., Rhizopus stolonifer and Aspergillus niger were found associated with the pre-harvest deteriorating soursop . B. theobromae was the most prevalent and the most pathogenic inducing rot of 75 mm in diameter within four days of inoculation. There was a remarkable reduction in carbohydrate and protein contents of the fungal infected fruits while all other nutrients and mineral assayed were higher in the infected fruits than the non-infected ones.

Ammonium molybdate was tested as a potential fungicide for use in apples (cv Golden Delicious) against blue and grey mould, important post-harvest diseases of pome fruits. In tests in vivo at 20 degrees C, ammonium molybdate (15 mM) reduced lesion diameters of Penicillium expansum, Botrytis cinerea and Rhizopus stolonifer by 84%, 88% and 100% respectively. When apples treated with ammonium molybdate were stored at 1 degree C for three months, a significant reduction in severity and incidence of P expansum and B cinerea was observed in both year...
The aim of this study was to investigate faecal shedding and transmission of Campylobacter spp. in cohorts of cattle within a feedlot, to assess subsequent contamination of carcasses with this pathogen and to identify risk factors associated with faecal shedding of Campylobacter spp. A cohort of 133 heifers housed in four adjacent pens was examined over a five and a half month period, from entering the feedlot to slaughter. A parallel investigation of individual rectal faecal samples and pen environmental samples were taken at monthly intervals...
INTRODUCTION: Despite renewed clinical interest in radial artery grafts (RA) for coronary artery bypass grafting, there is a paucity of controlled prospective data on its efficacy. We report on the rate of harvest related complications from a randomized radial artery study. METHODS: Two hundred eighty nine patients were divided into two groups. Group 1 received RA grafts (n=154 patients) and Group 2 (n=135 patients) received saphenous vein grafts (SVG). Postoperative wound problems were assessed using a questionnaire. Postoperative harvest site...
PURPOSE: We assess the medium and long-term morbidity of buccal mucosal graft (BMG) harvest for urethroplasty, and evaluate the effect of nonclosure of the graft harvest site on postoperative pain. MATERIALS AND METHODS: A questionnaire was mailed to 110 men who underwent BMG urethroplasty between January 1, 1997 and August 31, 2002. Demographic data and side effects of BMG harvest, including oral pain, sensation and intake, were assessed postoperatively. A prospective study was then performed to compare 20 unselected men whose BMG donor site w...
BACKGROUND: Conventional open long saphenous vein harvest (OVH) is often associated with significant wound pain and serious morbidity in some patients with a resultant extended treatment period. Endoscopic vein harvest (EVH) in theory should alleviate wound pain, be less predisposed towards leg wound infection and lead to greater patient satisfaction. This study aims to compare the two techniques on this basis and determine whether EVH is a viable technique within normal operative time. METHODS: During September and December 2000, 60 saphenous ...
BACKGROUND: The advantages of hamstring tendon autografts for anterior cruciate ligament reconstruction are well known; however, concerns have arisen regarding the influence of hamstring tendon harvest on postoperative weakness in knee flexion. PURPOSE: To evaluate the influence of hamstring tendon harvest on knee flexion strength in patients undergoing anterior cruciate ligament reconstruction. STUDY DESIGN: Prospective randomized study. METHODS: Ninety patients were randomly assigned at surgery to undergo anterior cruciate ligament reconstruc...
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether skeletonised internal mammary artery (IMA) is better than pedicle IMA in coronary artery bypass grafting? Altogether 106 papers were found using the reported search, of which 12 presented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these papers are tabulated. We conclude that s...
