Comparative efficiency of trawls made of nylon, polyethylene monofilament and tape twines

Results of comparative fishing operations conducted with three nets of identical design made of nylon, twisted polyethylene monofilament and high density polyethylene (HDPE) tape twines are presented in this communication. Since the tape net recorded the highest prawn and fish catch, monofilament and nylon following in order, it can be recommended to the fishing industry as one of the cheapest and effective fishing materials evolved for trawl fabrication

Endomyocardial fibrosis is possibly an interstitial heart disease

To obtain clues to the pathogenesis of endomycardial fibrosis specimens from 89 patients were studied histologically. When full blown EMF was present in one cardiac ventricle, the contralateral ventricle with either focal lesions or no visible lesions, had interstitial fibrosis associates with increase in interstitial cellularity. It is suggested that EMF may be a reactive and progressive interstitial fibrosis, a result of cardiac fibroblast growth,with or without proferation and enhanced collagen synthesis

Expression of proto-oncogenes and muscle specific genes during cardiac hypertrophy and development in rats and humans

A regulatory interdependence of expression of proto-oncogenes and muscle specific genes observed in smooth muscle was examined in cardiac muscle during normal development and hypertrophy both in rats and humans. During normal development in rats, myosin light chain 2 expression is very low at prenatal stages, while c-fos expression starts from the early stages of embryonic development. In aorta constricted rats c-fos induction occurs within 30 min whereas myosin light chain 2 expression is sufficiently high only after 3 or 4 days of post operative period. In the case of humans, the expression of myosin light chain 2 as well as c-fos occurs at high levels during embryonic development. Similar results were obtained with tissue samples obtained from patients with cardiac abnormalities. Induction of the c-fos gene in cultured myocytes by 12-O-tetradeeanoylphorbol 13-acetate has no influence on the expression of myosin light chain 2. These studies were extended with studies on c-myc and Β-myosin heavy chain gene expression which revealed a similar pattern of expression as that of c-fos and myosin light chain 2. These results have indicated that the expression of proto-oncogenes in cardiac muscle may be independently regulated from the expression of muscle specific genes

Probing the heart of cardiomyopathies

Current knowdedge of aetiopathogenesis of various forms of human cardiomopathy is reviewed in this article. There are overwhelming evidences to suggest a pathogenetic link between persistent viral infection, induction of autoimmunity (influenced by immune response determinants in the HLA region) and alteration in the differentiated functions of the myocardium in dilated cardiomyopathy. Genentic studies have identified specific defects in patients with hypertrophic cardiomyopathy but the cellular basis of the disease remains unresolved. Endomyocardial diseases associated with hypereosinophilic syndrome and endomyocardial fibrosis of the tropics appear to be two separate entities. A unifying link among endomyocardial fibrosis of diverse causes could be the uniform response of the cardiac tissue to injuries of heterogenous nature. Application of microtechniques to endomyocardial biosy promises definitive information on aetiopathogenesis of cardiomypathies

From the annals of plague

Giovanni Boccaccio, a contemporary of Dante and Geoffrey Chaucer is the father of Italian prose. His masterpiece the Decameron is a collection of tales, told to one another by ten friends who terrified of an epidemic of plague, field to an isolated villa
