CASE STUDY OF A PATIENT WITH BRONCHIECTASIS INTRODUCTION The respiratory system is divided into upper and lower respiratory system. The upper respiratory system refers to the nose‚ pharynx and associated structure while the lower respiratory system contains the larynx. Bronchiectasis is an uncommon type of chronic obstructive pulmonary lung disease. Bronchiectasis can be categorized as a chronic obstructive pulmonary lung disease manifested by airways that are inflamed and easily collapsible‚ resulting

The antibacterial activity of natural killer cells. Introduction Natural killer (NK) cells‚ a variety of granular lymphocyte‚ are the first line of defence against infections and cancer. First identified by their ability to “naturally” kill tumour cells previously unrecognised by the host (Kiessling et al.‚ 1975)‚ these bone marrow-derived innate killers were later recognised as a sepa-rate lymphocyte lineage‚ obtaining both cytotoxicity and cytokine-producing effector functions (Trinchi-eri

Aims The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different

Evaluation of antidiabetic and antimicrobial activity of jasminum grandiflorum leaves INTRODUTION 1.1. The pancreas and insulin formation The pancreas is an elongated organ situated next to the first part of the small intestine. It is both an endocrine gland that produces hormones‚ such as insulin and glucagon‚ and an exocrine gland producing digestive enzymes‚ such as trypsin and chymotrypsin (Martini‚ 2004). It is located behind the stomach‚ between the spleen and the duodenum (see Figure

Thi et al.‚ 2013). It has been found that the initial biota of herring fillet are dominated by Shewanella putrefaciens and Pseudomonas species. In addition‚ E. coli‚ Staphylococcus aureus and Clostridium perfringens have been identified from raw frozen seafood. A prevalence study of Aeromonas on catfish in a processing plant showed the predominance of Aeromonas and Pseudomonas spp.‚ Staphylococcus aureus‚ faecal coliform‚ E. coli and Salmonella in different frozen processed seafood (Thi et al.‚ 2013)

Topic: Cystic Fibrosis Introduction Cystic Fibrosis (CF) according to Cohen 2004‚ is the most common fatal hereditary disease amongst children and adults. It is an autosomal recessive disorder‚ and most carriers of the gene are asymptomatic. The flawed gene that causes CF affects the glandular secretions by altering chloride transport across cell membranes. Thickening of bronchial secretions leads to infection and other respiratory disorders. Other mucus secreting glands
