Abstract: The appendix averages 11 cm in length but can range from 2 to 20 cm. The diameter of the appendix is usually between 7 and 8 mm, the human appendix is considered a vestigial structure, acute appendicitis is the commonest cause of acute abdominal pain in the world and appendectomy is the commonest abdominal operation. Acute appendicitis occurred due to obstruction of the appendicular lumen producing a close loop with resultant inflammation that can lead to necrosis and perforation. The surgical removal of the vermiform appendix is called an appendectomy, either by laparotomy or laparoscopy. Untreated the inflamed appendix may rupture, leading to peritonitis, followed by shock, and, if still untreated, death may occurred. This study was carried out in Al-Hussein hospital in Nissirryia city through one year period from April 2004 to March 2005on360 patients,165 males and 195females.....

Abstract: Background: Plant-mediated silver nanoparticles have gained much attention in the past decade because of its features, such as being eco-friendly, effective cost, rapid and simple. Silver nanoparticles can be made by reducing silver ions using secondary metabolites which have reducing properties. Materials and Methods: In this study, Surian leaf extract (Toona sinensis) was used as a bioreductor in the formation of silver nanoparticles. Surian leaf extract was made by adding 5 g of Surian leaf powder into 50 mL distilled water, boiled at 90 oC for 15 min, and then filtered. Silver nanoparticles were made by mixing 0.2 mL of this Surian leaf extract with 0.5 mL of silver nitrate 0.1 M and the volume was adjusted to 50 mL with distilled water, then stirred with.....

Abstract: Background: The silver nanoparticle (AgNPs) biosynthesis is an interesting issue due to thehigher needs in various fields. The development of environmentally friendly technologies has been made by using primary and secondary metabolite reducing agents from microorganisms and plants. The biosynthesis of AGNPs can be made using only plant extracts, microorganisms or enzymes. The endophytic bacteria is a bacteria that lives and symbiotics with host plants, also produce potential metabolite compounds that can be used as a reductor to produce AgNPs. Materials and Methods: Endophytic bacteria were isolated from Surian leaves (Toona sinensis (Juss.) (M.roem)) obtained from the Medicinal Plant Garden of Andalas University. The bacteria were then purified by the streak plate method based

Abstract: Escherichia coli O157:H7 is a foodborne pathogen that causes disease in humans.It was first recognized as a human pathogen following an outbreak of hemorrhagic colitis associated with the consumption of undercooked ground beef in 1982. There have been several reports of E. coli O157: H7-related outbreaks throughout the world especially developing countries such as Nigeria.Food-borne pathogenassociated with E. coli 0157:H7 outbreaks is still being reported as the cause of hospitalizations and deathsdespite advances in food sanitation techniques and pathogen surveillance in developed countries. A promising approach that addresses most of these challenges is bacteriophage biocontrol, a natural and green method that uses lytic bacteriophages isolated from the environment to selectively target and eliminate pathogenic bacteriaor reduce their levels in foods. Starting....

Abstract: The emergence of new COVID-19 the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) create great public health crises in the world. Its genome sequence analysis indicated that the virus originated in bats and was transmitted to humans through yet unknown intermediary animals in Wuhan, Hubei province, China in December 2019. There have been millions of confirmed cases of Corona virus disease 2019 (COVID-19) and thousands of deaths have been reported. The disease is transmitted by inhalation or contact with infected droplets.....

Abstract: Studies on Pteridophytes in India were reported since British India by Beddome1. The Fern studies gained momentum after the establishment of the Indian Fern Society in 1983. Varieties of Pteridophytes are present in Himalayan mountain range, Eastern Ghats and Western Ghats of India and are in use by tribal people as food, medicine and ornamental plants since ancient periods. The distribution and diversity of Pteridophytes has been studied along east coast in parts of Tamil Nadu, Andhra Pradesh and Odisha. This review focussed on the effects of elevation, humidity, temperature and environment on Pteridophytes distribution. The present paper provides comprehensive review of studies on Pteridophytes carried out by researchers on east coast of India and presents the species of Pteridophytes that are becoming extinct. The effects of climatic conditions, rainfall, land use pattern and environmental effects on pteridophytes distribution and sustainability are highlighted.
