Introduction
Toxin-antitoxin (TA) systems incorporate pervasively in prokaryotic genomes that have also been suggested to perform a role in numerous critical cellular operations (Van, & Bast, 2009). These systems characteristically comprise of a two-gene operon encoding a toxic protein molecule which aims at an important cellular purpose and an antitoxin that connects to and hinders the toxin. Control of toxin action is attained via differential constancy of the stable toxin as well as the unstable antitoxin (Kamada & Hanaoka, 2005). In several occasions, the antitoxin also operates as a transcriptional autorepressor of the operon, whereby the degradation of the antitoxin leads to transcriptional introduction ...

Abstract

Stress is a dynamic and interactional process involving intricate body systems with formulations and operationalisation of the components at different levels(1).There is growing evidence that there is a positive correlation between emotional stress and oral health. As will be demonstrated from the literature reviewed in this paper emotional stress can be implicated in oral problems such as ulcerative conditions, inflammatory conditions, dental decay, TMD, RAS and others that continue to be linked to stress. Stress has also been found to aggravate some oral conditions such as oral lichen planus. In some of these conditions the precise mechanisms by which ...

Implementing Standard Practice for Collecting Blood Cultures Among ER Nurses

Abstract
Collecting blood culture samples is an important part of data collection for the process of diagnosis. The results of such a test can provide information regarding the presence of bacteria within the patient’s blood with great certainty. Therefore, it is an integral procedure for the verification of a prognosis. Unfortunately, there are a variety of factors that can lead to false positives of these tests. It mainly occurs due to the improper collection practices. This is most seen among the emergency room nurses. Because of the great risk associated with diagnosis and future medical treatments based on incorrect test ...

The results of such a test can provide information regarding the presence of bacteria within the patient’s blood with great certainty. Therefore, it is integral to the verification of a prognosis. Unfortunately, there are a variety of factors that can lead to false positives on these tests. One way this can occur is through improper collection practices. This is seen amongst emergency room nurses to varying degrees. Because of the great risk associated with diagnoses and future medical treatments based on incorrect test results, it ...

Introduction

Composition of Dietary Fiber
Dietary fiber is an essential component in nutrition and health (Mora et al., 2013; Klosterbuer, Roughead, & Slavin, 2011). Thus, the present study will explore the effect of particle size and source of fiber on the level of cholesterol in the human digestion system. Primarily, dietary fiber is a constituent of plant foods and includes materials that have diverse morphological and chemical structure. Such materials resist enzymatic action in the human digestion system (Dhingra et al. 2012). In the gastrointestinal tracts, the dietary fiber forms a matrix that has both amorphous and fibrous characteristics. The matrix’s ...

Implementation of the VAP project is a significant step aimed at ensuring that the objectives of giving patients outmost care, improvement of nursing practices and achieving desirable patient’s outcomes on the mechanically ventilated patients in the critical care unit are realized. Nevertheless, there is the need for making sure that all the relevant implementation stages have been followed and adequately taken into consideration. This will ensure any possible hitches that may affect project execution along the way are equally addressed. Additionally, it will be imperative that well-informed decisions are made with the intentions of ensuring that all the ...

Introduction

When a substance is termed as organic, it means that it is produced using through environmentally friendly methods. Ideally, organic substances are not artificial. Organic substances are environmentally friendly. A produce is something that is created. Therefore, organic produce refers to substances that are produced by methods of organic farming. Organic farming does not encourage the excessive use of modern inputs. These inputs include synthetic pesticides and fertilizers that are composed of excess chemicals (Gupta, 2007). Ideally, there is a difference between organic foods and conventional foods. Organic products are produced in compliance with organic standards that are set by the ...

Introduction

Antigen Presentation
Antigen presentation plays a pivotal role in the immune system through which pathogenic antigens are processed and coupled along with major histocompatibility complex (MHC), and presented to T cells for their effector response. Macrophages, B cells and dendritic cells are the primary antigen presenting cells (APC’s). Intracellular antigens generated by viruses, or some cytoplasmic bacterial antigens are digested by the host cells and coupled with MHC Class I by Transporter associated with antigen Processing complex (TAP), which transports them to the cell surface and presents to CD8+ cytotoxic T cells (Germain, R 1994). These cells elicit a ...
