Alcohol is the world’s oldest known drug that is abused by people. Alcohol has been used by many people for several years and its abuse has become a major societal health problem. The consequences of excessive alcohol intake vary from a mild hang-over to mass destruction, diseases, and death at its worst. When consumed in moderation, it has no or little effects for the drinkers and the people around them. Nonetheless, its misuse has become very dangerous to the drinker and the society. We all agree that, occasional taking of alcohol does not hurt, nonetheless it can lead to addiction ...

Abstract

The number of people being affected by various diseases that require them to have organ transplants increases every day. Meanwhile, the amount of donated organs is extremely insufficient to meet the high demand. There is also the problem of finding a donor match for a recipient and the need to take strong medications that suppress the immune system of the recipient so that the transplanted organ is not rejected. A solution to these problems has been and is still being developed, with laboratory-grown organs holding much promise. These organs can be tailor-made using the patient’s own cells or other cell sources, ...

Introduction. Night blindness is one of the early warning signs of a deficiency in Vitamin A. Each year, between 250,000 and 500,000 children lose their sight because they do not consume enough Vitamin A, and half of those will die within twelve months of losing their sight. Also, many pregnant women in developing countries suffer from night blindness as a symptom of Vitamin A deficiency, a problem compounded by mortality during pregnancy and childbirth, as well as difficulties in birth and in performing lactation (Rahi, et al., 1995, p. 332). In addition to night blindness, Vitamin A deficiency can impair ...

Vitamins are essential organic nutrients required in minute amounts for the body's optimal functioning. They could be water soluble or fat soluble. Water soluble vitamins include; vitamins Band C, while the fat soluble vitamins are; Vitamins A, D,E,K. Vitamin A was the first fat soluble Vitamin to be discovered in 1913.

Vitamin A's structure is depicted to the right. Retinol is the precursor of of retinal and retinoic acid. Both are active metabolites of retinol. Retinal plays an important role in vision while retinoic acid is the intracellular messenger which affects the transcription of some gene( Bates ...

Introduction

One of the byproducts of urban growth and development is the waste production. As per the report of the World Bank (2013), OECD countries produce almost half of the world's waste, while South Asia and Africa are listed as the regions producing the least amount of waste. The Basel Convention defines 'wastes' as substances or objects that need to be disposed of in accordance with the provisions of national law. European Waste Catalogue shows 850 types of wastes out of which 420 types of wastes have been classified as hazardous waste. Hazardous wastes are those wastes considered to be ...

Introduction

Childhood obesity as a medical condition affects a lot children across the world. According to Dieticians Association of Australia (2014) childhood obesity is when a child has too much body fat and the child’s weight is well above normal for his or her age and height and this puts their health at risk. In Australia as well and in fact, across the world, the community is becoming increasingly concerned with the rising prevalence of childhood obesity (Jacqueline. 13). The health consequences for obese children at their current status as well as in the future has acted as an impetus for raised ...

Abstract

Diabetes mellitus (DM) is a lifelong metabolic disorder which is caused by the abnormal level of sugar in the blood. The information technology is playing an important role in the seamless data collection of the diabetic patient’s glucose and insulin level, heart rate, and weight and transfer through different devices and made it available to the health practitioner for their observation. This helps the diabetic patient in self management of their health based on the data processed by the apps present in the phone or devices. This paper reviews the information technologies role and benefits in the management ...

INTRODUCTION

Stem Cell research is a controversial topic that has and continues to spawn heated debate. While the potential of stem cells research is endless it comes with a number of ethical considerations. Stem cells are like blank cells that can transform into whatever cells they are surrounded by; if placed in the liver they can become liver cells, the same in the heart or the a kidney. However, the research remains controversial because the richest source of stem cells needed to further the research are most often found in the tissue of aborted fetuses. This brings up many ethical questions that have ...

[Low flow anaesthesia with isoflurane in the dog].
This article in german compares the safety of high and low flow anesthesia in dogs preparing for surgery. Three groups of animals were divided into two low flow and one high flow groups. Vital signs were kept well controlled during the procedures. Notes the highest decrease in body temperature was in the high flow group, and a particularly cooled gas used for that group may have caused this.
At least in the context of dogs, this article seems to treat the question of flow rate and core body temp. as a ...

MicroRNAs are small, single-stranded, non-coding, 16–29 nucleotide RNA molecules comprising of an evolutionarily conserved class of endogenous ribo-regulators that regulate gene expression (Wiemer, 2007; Garzon et al., 2009). They were discovered in 1993 in the nematode Caenorhabditis elegans (Espinosa & Slack, 2006). Currently, 4167miRNAs are listed in the miRNA registry and 474 human miRNAs have been identified (Wiemer, 2007).
MicroRNAs are crucial for the development of vertebrates due to the fact that depletion of the components of the miRNA processing pathway, or interfering with maturation of miRNAs, is not compatible with life (Wiemer, 2007).
The miRNA ...

MicroRNAs are small, single-stranded, non-coding, 16–29 nucleotide RNA molecules (approximately 22 nucleotides in length) comprising of an evolutionarily conserved class of endogenous ribo-regulators that regulate (modulate) gene expression (Wiemer, 2007, p.1529; Zhang et al., 2006, p.9136; Garzon et al., 2009, p.168). They were discovered in 1993 in the nematode Caenorhabditis elegans (Espinosa & Slack, 2006, p.131). Currently, 4167 miRNAs are listed in the miRNA registry and 474 human miRNAs have been identified (Wiemer, 2007, p.1530).

The miRNA genes are dispersed across the genome in gene clusters or as single genes. At least 50% of the miRNA genes are ...

Introduction

Cilia are ancient and evolutionarily conserved organelles which are found on cell surface. This organelle project from those cell surfaces to provide multifunctional biological roles in the organism. An important role that cilia has been known to perform for cells are the locomotion, sensation and reproduction. The implication of the defect in the cilia is that the cell that tend to depend on the organelles for proper performance will be limited in it role. There are many diseases that have been found to be associated with cilia defects. Since cilia occurred as important organelles of many cells, majority of ...
