THREE-DIMENSIONAL PRINTING OF SCAFFOLDS FOR TISSUE ENGINEERING

Image
For biomedical applications, 3-D printing has established its appreciable potential in the production of functional scaffolds. Day by day increase in advancement in the techniques of 3D printing gave rise to hope for enhancements in regenerative medication. The aim of this field of research is the use of stem cells and different techniques to replace and repair the injured organs, cells, or tissues. Basic concept of Tissue Engineering: In 1993, tissue engineering concept was formalized in a paper by two scientist Langer and Vacanti, applications and characteristics of biodegradable 3-D scaffolds were described in detailed (An, J. et al., 2015). Tissue engineering is a developing branch, in which tissue scaffolds are used for the development of new tissues and these tissues used for various medical purposes. After many years of continuous efforts, a group of tissue culture, implantation replacement technologies have been established, which allows artificial extracellular fabricati

Green Nanotechnology

Green Nanotechnology: Hope for future Nanotechnology is the fastest growing discipline of science providing vast applications from house hold appliances, drug delivery, diagnostic and therapeutic techniques, nanorobotics, nanochips to powerful building materials. However, besides tremendous benefits of nanotechnology there are some concerns leading towards the thoughts that it might be unsafe for environment and human health to use nanomaterials. To overcome such environmental issues there is a new branch developed named as ‘Green Nanotechnology’ which is sometimes refers as clean nanotechnology. Now, scientists are giving priority to green nanotechnology because it promises to produce clean technologies in present and also in future.   In Green Nanotechnology, eco-friendly nano-products and processes are used to increase the environmental sustainability and to reduce human health risks due to the use of unsafe nanoparticles. Green nanotechnology actually uses the principles of

Nutritional Intervention for the treatment of Covid-19

Image
1. INTRODUCTION Nutrition is the key element of health and care. It plays an important role in the maintenance of health and treatment of severe clinical diseases [1]. More importantly, it enhances the host immune response to fight against the viral infections e.g. COVID-19 [2]. Proper nutrition and hydration are the key factors for a strong immune system. People who consume good and well-balanced diet have less chance of getting infected by any pathogen. Mostly immunocompromised, elder and comorbid people are found to have COVID-19 [3]. While the disease is less likely to occur in children and young because of a strong immune system. So, we should eat a variety of fresh and healthy food to get the required amount of vitamins, proteins, dietary fibre and iron [4]. 2. NUTRITION SUPPLEMENTS 2.1. VITAMIN A Vitamin A is an important nutritional component of the human body which is also known as an anti-infective vitamin. It is responsible for the strong immune responses against many vi

How much coffee we should drink?

Image
Most people need a cup of coffee to start their morning, to keep them awake and to increase their productivity. It is a popular beverage that is widely consumed around the world, it is rich in many bioactives and antioxidants. However many coffee lovers want to know how much coffee is safe to drink and whether its excess intake has any risks. Coffee and caffeine: When you think about coffee caffeine is the first thing that comes into your mind. Caffeine is an active ingredient of coffee, it works by stimulating the central nervous system, heart and muscles. The amount of caffeine in a cup of coffee is variable from 70 to 400 mg per cup. How much coffee you can safely drink? Several studies have found out that daily intake of four cups of coffee is a safe amount. Even federal dietary suggests that three to five (eight ounces) cups per day (containing 400mg of caffeine ) is the healthy diet. Pregnant women should limit the intake of caffeinated coffee to one (12 oz) cup which is

HOW MESENCHYMAL STEM CELLS WORK AGAINST COVID-19?

A person who lives in twenty-first century will not forget word “COVID-19”.Corona virus (COVID-19) has grown very rapidly in the whole world from December 2019. COVID-19 named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in February 2020 by International Committee on Taxonomy of Viruses (ICTV). A patient of coronavirus disease was first detected in Wuhan, China, in December 2019 and then it has grown to be a global disease (Zhao, R. C., 2020). Seeking treatments against COVID-19: Many researchers or scientists who are belongs to biomedical fields are seeking treatments, medication or solution against COVID 19. For the curing of covid-19 multiple medicines are investigated including anti-inflammatory, anti-viral and anti-malarial agents. However, no specified treatment for COVID-19 has been discovered yet. Perhaps, preventing infection of the acute respiratory distress syndrome (ARDS) form of coronavirus 19 as the very dangerous stage of this disease could be ver

Salmonella food poisoning

Image
HISTORY Salmonella were the famous and foremost of the food poisoning organism for almost the whole of the 20th century. Before 1880s, food poisoning had been described to chemical changes in decomposing food items. From the early 1880s, however it come to be considered as being due to bacterial infection associated with the consumption of animal food like: Beef, pork, and milk also manipulated food items such as pies, cream, cakes and ice cream. In 1900, the salmonellas represented a new and interesting route for medical research of the cause of human illness like: Microbiologist, Epidemiologist, and public health administration. In 21st century a widely greater understand of salmonella’s structure, natural history and relationships had been started. The disease is characterized by abdominal pain, nausea, vomiting and watery diarrhea and sometimes: muscular weakness, restlessness and dizziness the first source of food poisoning in humans are from the intestinal track of animals

Hanta Virus

Image
1. Introduction Hantaviruses are the rodent borne viruses that cause severe clinical illness in human. Each strain of hantavirus is specific to a particular rodent host and cause and different clinical disease [1]. It belongs to the family of Bunyaviridae. The virus was recognized as a pathogenic virus in the previous decades. First case of hantavirus was diagnosed in 1993, during an endemic in Southwestern U.S. In human, it usually cause two types of disease including Hantavirus pulmonary syndrome (HPS) and Hantavirus hemorrhagic fever with renal syndrome (HFRS) [2]. Nephropathia epidemica (NE) is another disease caused by hantavirus, mostly seen in Europe. 2. Structure of Hantavirus Hantaviruses are the enveloped viruses having three negative sense single-stranded RNA segments designated as small (S), medium (M) and large (L) as shown in Figure 1. S segment is involved in the coding of Nucleocapsid protein (NP) while M and L segments are coding for the surface envelope glycoprote

Nutraceuticals

Image
“Food Is a Medicine of Health” HISTORY: Scientists are continually trying since the ancient period to make medicines from natural material and used for the treatment of disease. A physician hippocrates who is known as the Father of medicine, said that “let thy food be thy medicine and the medicine be thy food” (Chanda, S, et al., 2019). Stephen DeFelice, founder and chairman of the Foundation for Innovation in Medicine (FIM), coined a term “nutraceuticals” in 1989.The word nutraceutical is a combination of two words “nutrition” and “pharmaceutical” (Kalra, E. K. 2003). INTRODUCTION: Any substance that is either a part of food or food that provides both health and therapeutic benefits are called nutraceuticals. It can be used for the prevention and treatment of disease without any health effect (Shinde, N, et al., 2014). Nutraceuticals play a vital role in maintaining body health and prevents the body from diseases by provides essential supplements to regulate metabolic
