A desk as an inanimate object is alive despite the fact that all the physical characteristics prove that it is not. Ideally, this is because the desk possesses several properties of life that prove it is indeed alive. First, a desk reflects the characteristic of responsiveness; it responds to the changes in the external environment. For example, dipping a desk into the water for a long time will decree its hardness. In particular, this shows that it has absorbed a lot of water within the period set. As a result, it reflects characteristics of living plant organisms that absorb ...

Introduction Cirrhosis is caused by liver injury that results in fibrogenesis and inflammation. These problems result in collapse of liver structures and significant distortion of hepatic vascular structure. This distortion leads to elevated resistance to portal blood flow as well as portal hypertension. Moreover, hepatic synthetic dysfunction is also caused as a result of these problems. Clinically, liver cirrhosis is considered as an end-stage disease that could result in death until liver transplantation is performed (Tsochatzis, Bosch, & Burroughs, 2014). Liver cirrhosis is an important cause of morbidity and mortality in most of the developed countries. In ...

It has never been a secret for people that physical activity stimulates the brain and provokes its development.

Raman spectroscopy is dependent on scattering of light. When light interacts with matter, energy exchange can take place through absorption, simulated emission, Raman scattering or spontaneous emission. In Raman scattering, the emitted photons have less energy and lower frequency in comparison with the absorbed photons. Some energy of the emitted photons is transferred to the molecules. Raman spectroscopy is a method which collects the chemical fingerprints associated with molecules. Every molecule has different levels of vibrational energy and the emitted photons experience shift in their wavelengths. The wavelength shifts are collected,examined and analyzed for sample identification. Raman spectroscopy ...

Since ages, abortion has been a controversial and debatable topic in the country. Currently, the legal aspect of abortion has caused a stir in the masses. This matter can be discussed in the light of two opposing viewpoints professed by two personalities. For women, abortion is not as binary as it is considered and being pro-life or pro-choice is not a decision that anyone can make a certain set of principles which they have come to know of. This is exactly what TV show host and analyst, John Oliver discusses in a light-hearted manner on the show ‘Abortion Laws: ...

OVERVIEW

In the terminology of the WHO, AIDS is a viral disease that prevents the body to fight against infections and cancer ("HIV/AIDS", 2016). AIDS infected people are easily affected a large number of unusual and life-threatening diseases. These diseases are often treatable; however, successful treatment based on immune deficiency is caused by a virus there. The causative agent of AIDS is HIV (human immunodeficiency virus). The name was adopted in 1986 as a term to describe the virus that causes AIDS. This allows the name itself to distinguish AIDS from other retroviruses and evidence offline. This virus was known ...

Governmental legislation on prohibiting toxic materials and prevention and control of the volume of waste has helped in decreasing adverse environmental effects. There is a growing public awareness about waste prevention and its beneficial effects. The society has to replace the linear model of extract-produce-consume-dispose to closed Loop's approach of resource recovery and waste ...

The Challenge of Antibiotic Resistance: Has our use of Antibiotics Caused more Problems than it has solved?

Antibiotics are medicines which have bactericidal or bacteriostatic properties and used in treatment or prevention of microbial diseases (NPS 2012). Antibiotics a have been in existence for a long time and were initially known as antibiosis which meant against life, and by Jean Paul Vuillemin first used this term. He used the word to describe the properties which were exhibited by the early antibacterial drugs. In 1877 Antibiosis was first described by Louis Pasteur and Robert Koch when they observed the inhibition of growth of Bacillus anthracis by an airborne bacillus. In 1928 penicillin was identified by Alexander Fleming. ...

Rocky mountain spotted fever is tick-borne infection. In endemic areas, the prevalence of the diseases is 15 per 100,000 persons. The disease is characterized by sudden onset of fever and headache. It is caused by gram-negative intracellular bacteria Rickettsia rickettsii. The bacteria have a high predisposition for the endothelial cell. Actin protein polymerization in the cells is important for the spread of bacteria from one cell to another. (Raoult & Parola, 2007) The bacteria cause lymphohistiocytic vasculitis and necrosis of the infected cells. It typically takes 5-7 days from the day of tick bite to the onset of symptoms. ...

The human body is wired to function normally by maintaining a certain optimum functional state. Homeostatic mechanisms ensure that the body remains viably stable by maintaining the internal atmosphere within the functional limits. Alteration of the cells functionality brings about an unusual state in the body system. Interruption of homoeostasis causes the body to respond by correcting the state in a bid to restore the normal functionality. Lifestyle decisions such as nutrition and physical exercises directly affect homoeostasis which in most cases leads to a state of disease such as anaemia. Nutrition is a major factor that affects the ...

Abstract

The immune and nervous systems are two body structures that have different functions. Moreover, most people may not be able to readily identify the and the relationship between these two. While the immune system is responsible in protecting the body from destructive and invading pathogens, the nervous system is tasked to relay information to the brain. This process allows for the proper coordination of the different functions of the body. In general, the concept of the connection between the nervous and the immune systems stems from the theoretical idea of stress. Stress is denoted both as a physiological and ...

Abstract

Regretfully, diagnosis of diabetes is very common nowadays. Diabetes has become a worldwide epidemic and one of the leading causes of premature morbidity and mortality because it often leads to amputation of limbs, loss of sight, kidney failure and provokes cardiovascular disease. However, it is not that hard to suspect a high risk of developing diabetes or the disease itself before the analysis of blood sugar levels. Many of the signs of diabetes are visible to the naked eye. Paying attention to them in timely manner can avoid the severe consequences of the disease. Patients with diabetes can lead ...

The Relationship between H. Pylori Infection and Mitochondrial Microsatellite Instability in Gastric Carcinogenesis

Recent research has established that while there are a number of steps that take place in the development of gastric cancer, Helicobacter pylori (H. pylori) plays a major role. However, the mechanism of the influence remains unidentified. Researchers Ling et al. (2016) conducted a study to determine relationships between an infection of H. pylori, IL-8, and mtMSI and whether there is a trigger that causes the infection to progress to intestinal metaplasia, dysplasia, and ultimately to gastric carcinogenesis.   The method used by the researchers included fresh samples from resected gastric cancerous cells and comparison samples of potentially pre-cancerous mucosa; ...

Click Chemistry describes the biocompatible reactions that are high yielding, that are very simple to perform, have wide scope, that need no chromatography to remove their byproducts and that can be conducted in easily removable solvents. The synthesis of first triazole was reported by Arthur Michael in 1893. In the 20th century, Huisgen discovered the catalyst of copper, 1,3-dipolar cycloaddition which required the temperature of 100 degree Celsius. This reaction of copper is a highly versatile reaction which does not require any specific reaction conditions and can easily be performed with various solvents, wide temperature range and pH, ...

These molecules or system that are constructed, help to complement natural biological systems and help in performing particular biological task (Khalil and Collins 367-379). A simple example of synthetic biology would be manipulation of bacteria through recombinant technologies to produce recombinant protein. A vast number of applications are possible with synthetic biology. With the advancement that are currently happening in the area of bioinformatics, it is possible to reprogram human ...

1. Biot’s respiration named after Camille Biot is an abnormal ataxic breathing pattern, where rapid series of shallow respiration are followed by a period of apnea. In order to known how AMP kinase, knock down leads to Biot respiration in mice; it is necessary to known how AMP kinase affects respiratory rate. AMP kinase is a metabolic sensor and is activated in response to stretching of the lung alveolar cells and other stressors. During respiration, the lung goes through cycles of expansion and contraction (Budinger et al., 2008). When the alveolar cells stretch during expansion, the 5′ AMP-activated ...

Ebola virus disease, formerly described as Ebola hemorrhagic fever, refers to a severe illness that is usually deadly in humans. Wild animals transmit the virus to human populations where it spreads through direct contact with infected bodily fluids. Typically, the disease has a fatality rate of nearly 50% with past outbreak cases recording fatality rates ranging between 25% and 90% (World Health Organization (WHO), 2016). For example, an Ebola epidemic in West Africa reported in 2014 caused global panic because it was “the largest and most complex Ebola outbreak since the Ebola virus was first discovered” (WHO, 2016).

Cycle of communication within and between neurons

The understanding of the communication process between and within neurons or the nerve cells helps us to gain knowledge of the functioning of the human brain. Neurons gather information relating to an organism’s internal state as well as the external environment continuously and perform an evaluation of this information and the coordination of appropriate activities depending on the situation and person’s needs. Communication between and within neurons occur through the transmission of nerve impulses, which in essence are coded signals produced by certain stimulus along the neuronal membrane. Communication within neurons occurs through a chemical process whereby ...

THE SCIENCE OF FOOD

Cancer and nutrition – good nutrition is very important in the management of cancer and thus healthy eating habits are encouraged during this period. Tumors that develop in the stomach or intestines may, however, affect the way the body uses the food that is ingested and may not absorb all the food, although the patient may be seen to be eating enough food. The side effects that may affect eating when one has cancer include vomiting, dry mouth, constipation, mouth sores, loss of appetite among others. Nutrition therapy is advised for cancer patients to help maintain a good quality life ...

There are many different types of virus and bacteria that can have a negative effect on the human body; some are internal, while others are external. One such bacterium is Staphylococcus, which leads to infection in many human beings. The Staphylococcus bacteria is responsible for a number of different types of infections, they are described as being spheroid shaped, gram-stain positive sometimes seen in singular, in pairs, or very often in clusters; this is often contributed to being described as a bunch of grapes (Davis 1). Human beings are most susceptible to two specific strains, staphylococcus epidermidis and staphylococcus ...

Living things have specific superior characterizes that distinguish them from nonliving items. Living things are characterized by their internal organization, which is composed of cells (Alcamo, 1998).

A rock to a snail

Ideally, a snail is a living thing while a rock is a nonliving. The two differ widely based on the eight characteristics of living things. A snail performs nutrition to obtain energy and experiences respiration as energy is released for use in the cells. Also, a snail moves to different locations since it responds to stimuli and it excretes due to chemical reactions in the body. Additionally, a snail ...

Tuberculosis is a serious bacterial infection that is usually spread from one individual to the other by inhalation of very small droplets originating from the sneezes or coughs of an infected person. The bacteria that causes TB is known as Mycobacterium tuberculosis (Kelly, Wilker, & Ambrose, 2011, p. 14). The main organ affected by the disease is the lungs (also called pulmonary tuberculosis) but it can also affect bones, the nervous system, and the glands. Each droplet of sneeze may contain between 1 to 400 bacilli each. Because the disease is airborne, the bacterium can also be transmitted to a ...

Fetus development begins with a single cell which grows into a body of over one hundred trillion cells. The process of reproduction requires male sperm to fertilize the female egg. Millions of sperm race to achieve this task and each one of them has a unique genetic combination. Twenty-three chromosomes from the female and an equal number from the male combine to form an x shape. Later, two of the x shaped chromosomes join and different genes move between the partners. Later, gastrulation occurs in the lining of the uterus. The different types of genes in a cell lead ...

Bacteria refer to the regnum of prokaryotes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan). For the current moment, it accounts for more than ten thousand kinds of bacteria. The bacterium is recognized as one of the most ancient of living organisms, arising about 3.9 – 3.5 billion years ago. Bacteria have the substantial variation in the ways of metamorphic and energetic metabolism. Thus, autotrophs can synthesize all necessary organic molecules from non-organic compounds, whereas heterotrophs demand active organic compounds to transform them. The biggest degree of heterotrophs belongs to intracellular parasites. They are called saprophytes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan) and can ...
