UNLABELLED Tinnitus is a common auditory complaint among individuals exposed to noise. AIM this paper aims to study the characteristics of tinnitus in workers exposed to noise. STUDY DESIGN this is a descriptive prospective study. MATERIALS AND METHOD Fifty-two individuals averaging 29 years of age were enrolled in a hearing loss prevention program at a meat processing plant. The particip...

Many large mammal species are declining in African savannas, yet we understand relatively little about how these declines influence other species. Previous studies have shown that the removal of large herbivorous mammals from large-scale, replicated experimental plots results in a dramatic increase in the density of small mammals, an increase that has been attributed to the relaxation of compet...

OBJECTIVE This study aimed to describe the structure of governmental surveillance systems for Healthcare Associated Infection (HAI) in the Brazilian Southeastern and Southern States. METHOD A cross-sectional, descriptive and exploratory study, with data collection by means of two-phases: characterization of the healthcare structure and of the HAI surveillance system. RESULTS The governmenta...

The gene encoding nucleosidediphosphate kinase (ndk) was located at 55 units on the Salmonella typhimurium chromosome. The ndk locus was 83% cotransducible with hisS and 2% cotransducible with glyA in phage P22-mediated crosses. A nucleosidediphosphate kinase mutant that produced only 10% of the wild-type enzyme activity (ndk-1) grew normally and produced a heat-labile enzyme.

Tinnitus is an important complaint or disease or a combination, especially within our aging population. Neurootologists clinically deal with many different disorders of the human cranial senses, of which tinnitus is a very frequent type. With respect to neurootological clinical work, we delineate at least three groups of tinnitus. In bruits, patients complain of noise within the head (e.g., bub...

INTRODUCTION A hospital information system has potentials to improve the accessibility of clinical information and the quality of health care. However, the use of this system has resulted in new challenges, such as concerns over health information security. This paper aims to assess the status of information security in terms of administrative, technical and physical safeguards in the universit...

Defining an acoustic repertoire is essential to understanding vocal signalling and communicative interactions within a species. Currently, quantitative and statistical definition is lacking for the vocalisations of many dasyurids, an important group of small to medium-sized marsupials from Australasia that includes the eastern quoll (Dasyurus viverrinus), a species of conservation concern. Beyo...

national health information network (nhin) is a network in which all health care organizations, government agencies and other health-related organizations are connected to each other to exchange information about health. due to the necessity of a framework for nhin development, in this paper, according to the literature review, a definition for nhin framework was provided, and then the nhin rel...

in the last two decades, the trend in healthcare information technology has been towards digital and multimedia concepts. the next generation of healthcare information systems will consist of a vast network of heterogeneous, autonomous and distributed imaging scanners, hospital information systems (his), medical information from clinical departments such as radiology information systems (ris), ...
