Essays on Toxicity

Cell culture is an in-vitro technique of cultivating cells under controlled conditions and in sterile conditions. The technique was first developed by Ross Harrison in 1907. During the process of cell culture, the cells are detached from their tissue of origin and segregated from each other, either by mechanical or enzymatic means. The detached cells are then transferred before culturing them in cell culture plate or flask. The first generation of producing cell through this method is called primary cell culture. The cells from the primary culture are transferred to a new culture plate with a fresh medium to ...

Immunogenic cell death: the role of SAGE

Immunogenic cell death: the role of SAGE

Introduction

Millions of cells are always being removed in the human body not only to regulate and coordinate the body’s biochemical pathways but also to keep the cells healthy. This particular systematic removal of cells occurs through a selective mechanism called cell death or apoptosis process. Apoptosis is not a new concept in the understanding of the biological workings of the body. This homeostatic death of body cells has been defined as a tolerogenic or a non-immunogenic event for many [1]. However, new discoveries have unearthed the existence of a different concept ...

Full title- A COMPARISON OF THE INHIBITORY EFFECTS OF METAL IONS

Enzymes are an essential part for the functioning of the human system. Most of the enzymes require binding of metal ions and other non-protein components for their appropriate functioning. Such non proteins, which facilitate the functioning of enzymes, are called cofactors. The cofactors can be an organic cofactor as Thymine Pyrophosphate (TPP), Flavin Adenine Dinucleotide (FAD), Nicotinamide Adenine dinucleotide (NAD); or inorganic cofactors like metal ions, Mg2+, Cu2+, Mn2+, Zn2+ and Iron-sulphur clusters. When the enzyme is bound to a cofactor, ready to carry out its function, it is known as a ‘Holoenzyme.' An enzyme without a ...

- What is Lipinski’s Rule of Five and why is it important to drug design?

Lipinski's rule of five is popular as the Rule of five (RO5) or Pfizer's rule of five. It is a standing rule that evaluates drug likeness in determining whether chemical compounds that have certain biological or pharmacological activities have properties that make it a probable orally active drug for human consumption. This rule is on observing that many medication drugs have lipophilic molecules (Anastas 56). This means that the rule is applicable in drug discovery when lead structures that are pharmacologically active optimized. This increases the activity and compound selectivity insuring proper maintenance of drug-like physicochemical properties as illustrated ...

Oral or parenteral iron is given to patients in severe anemia. Therefore, their use is regulated by clinical guidelines to reduce the ...

1942, Selman Maksman coined the word antibiotics. They are substances that are produced by microorganisms. They either slow down the growth of other bacteria or kill them right away. Examples include the beta-lactam antibiotics which consist of the penicilins. Others include the Carbapenems, the cephalosporins, the aminoglycosides, quinolones, sulfonamides and the oxazolidinones. Also, they could be classified as either bacteriostatic agents that slow down or inhibit the growth of bacteria or bactericidal agents which kill bacteria. Their discovery and use in medical science is of immense magnitude. They equally reduce the rate of mortality and morbidity of patients infected ...

Animal testing refers to the scientific research and experiments conducted on the animals. Animal testing is not new to the society and existing for past several years. Every year millions of animals are used for commercial testing and research purposes. Advocates of animal testing claim that it is essential for development of new life-saving medicines and treatments, especially in absence of any other suitable alternative method. Opponents of animal testing claim that it is inhuman to perform experiments on innocent animals, when alternative methods are available to scientists. Testing on animals also does not provide hundred percent assurance of ...
