1. Introduction The quantity and quality of osseous tissue available for implant insertion are vital for long term stability and predictability of an implant restoration in function (Branemark 1985) Research has shown that bone will resorb after tooth loss(Pietrokovski, 1975), this alveolar atrophy is a major problem that has limited the use of endosseous implants since their introduction.(Jensen, et al., 1994) The correct three dimensional placement of implants is vital to a successful esthe...
'It is easy to ask what people eat, but ï¬nding an answer can be a daunting task." [1] In our fast-moving world, few people would dispute the fact that one of the most fundamental problems that nutritional research is facing is the difficulties in assessing the intake accurately.[2] Dietary intake is generally considered to include all foods and beverages consumed by the oral route. Food, such as dietary supplements and spices, which contain energy or nutrients, must be, but not always, list...
ABSTRACT: INTRODUCTION: Dentistry has evolved into a highly stressful profession. Numerous studies have assessed stress in dental environment in Western countries. Finding of these studies cannot be extrapolated on developing countries like India due to cross-cultural differences. Hence, the present study was conducted to ascertain the validity and reliability of Stress Measurement Scale used to assess stress among students and staff in a dental institution in India. MATERIALS & METHODS: Item...
Squamous cell cancer (Head and neck) is the sixth most common cancer responsible for over 500,000 new cases annually worldwide (1) . 90 % of Head and neck cancer cells overexpress Epidermal Growth Factor Receptor (EGFR). Its presence not only leads to a poor outcome (2) , but also enhances resistance to cytotoxic agents, including ionizing radiation. The EGFR is a 170-kDa transmembrane receptor tyrosine kinase of the ErbB family. (3) The EGFR is composed of four extracellular domains, a hydro...
In 1906, Dr. Alzheimer became aware of the changes in the brain tissue of a woman who had succumbed due to a strange mental illness. Among the symptoms comprised of language problems, memory loss, in addition to unpredictable behaviour. After closely examining the brain of the woman, Dr. Alzheimer found many anomalous clumps - currently known as amyloid plaques - as well as tangled bundles of fibers referred to as neurofibrillary tangles. This makes Plaques and tangles in the brain to be two ...
Therapeutic drug monitoring refers to the individualization of dosage by maintaining plasma or blood drug concentrations within a target range (therapeutic range, therapeutic window). There are two major sources of variability between individual patients in drug response. dose and plasma concentration (pharmacokinetic variability) drug concentration at the receptor and the response (pharmacodynamic variability) By adjusting doses to maintain plasma drug concentrations within a target range, v...
Nanotechnology is working on matter at nanolevel (one millionth of a millimeter) and nanomedicine is the use of this technology in medicine for diagnosis and treatment. Although research results are far from application on humans; yet, research body is growing fast and collaboration between specialties is creating some great laboratory advances. The aim of this thesis is to review, in brief, the future, pros and cons of using nanotechnology in medicine. Definition Nanomedicine is a subsidiary...
Leadership Understanding the basic principles of leadership is paramount to the delivery of a successful project. I found that one of the difficulties of looking at leadership for healthcare professionals is that most of the theories were developed in a business context and were then applied to healthcare organisations. Because of the focus on organisational leadership, it is sufficient here to distinguish two important aspects of leadership. The first is that of providing direction, organisa...
Atrial fibrillation is a supraventricular arrhythmia characterized by rapid and disordered depolarization of the atria, where integrated atrial contraction disappears and is replaced by irregular fibrillary atrial muscle twitching. In atrial fibrillation, there is accompanying irregular rapid ventricular contraction, and although paroxysms may occur, yet, mostly atrial fibrillation (AF) becomes a permanent condition (Scott, 1973). AF is the most prevalent arrhythmia seen in clinical practice....
The study was based on critical analysis and review of literature in evaluating the supremacy of skin preparation antiseptic between chlohexidine and povidone-iodine. Chlorhexidine gluconate can reduce the risk for catheter-related bloodstream infection by approximately 50% and should be used in preference as an preoperative antiseptic agent in clean-contaminated surgery in decreasing postoperative SSI. This study demonstrated ChloraPrep solution good value for money as its use for skin antis...
