Hematopoiesis Hematopoiesis is the process of origin, development and maturation of all blood cells. Hematopoietic areas In the first few weeks of embryonic life, RBC are produced in the mesodermal region of yolk sac. During the middle part of the gestation liver, spleen and lymph nodes are the main organs of hematopoiesis. During the later part of gestation and after birth, bone marrow is the main organ producing RBC. Factors necessary for Hematopoiesis Erythropoietin – Erythropoetin is a glycoprotein produced by kidney to stimulate the production of more RBC. Thyroxine – it’s a hormone that accelerates the process of erythropoiesis. Hematopoetic growth factors – interleukin and stem cell factor Vitamins – Vitamins B,C, D, E are necessary for the process of hematopoiesis. ]]>

In recent years, ZnO nanoparticles gained tremendous attention attributed to their unique properties. Evidence has shown that zinc is an important nutrient in living organism. As such, both prokaryotes and eukaryotes including bacteria, fungi and yeasts are exploited for the synthesis of ZnO NPs by using microbial cells or enzymes, proteins and other biomolecules in their intracellular and extracellular route. ZnO NPs exhibits antimicrobial properties. However, the properties of nanoparticles are depended upon their size and shape, which make them specific for various applications. The present study deals with the synthesis, characterization and evaluation of antibacterial potential of ZnO NPs synthesized by Vigna mungo and Rhizobacteria. The rhizobacteria have been isolated from the root nodule of V. mungo and has been morphologically, biochemically and molecularly characterized and identified to be Rhizobium sp. strain P4 and Bacillus flexus strain IFO15715. The GC-MS analysis of methanol leaf extract of V. mungo carried out for the detection and identification of bioactive compounds and this revealed phytol as the antibacterial compound while Squalene and Alpha – tocopherol have antioxidant and antitumor property. The antibacterial potential of ZnO nanoparticles and leaf extract of Vigna mungo were expressed by agar well diffusion assay. The results showed both methanol extract and zinc oxide nanoparticles harbor significant antimicrobial activity on most of the tested organisms. The synthesized nanoparticles from Rhizobium sp. were characterized by analytical techniques like SEM, XRD, FTIR, and UV-Vis.]]>

Research on anthocyanins as a antioxidant compound is gaining attention. Banana (Musa X paradisiaca) bracts are abundant edible residues of banana production, is generally considered as a potent source of anthocyanins. Anthocyanins were extracted with acidified methanol, purified using silica gel coloumn and characterized by UV-visible spectroscopy. The isolated anthocyanins were used to check the effect on UV induced cell death in fibroblast cells and from our results it can be observed that anthocyanins at lower concentrations effectively restored cell viability when determined by MTT assay. An increase in cell viability to 85% from 54.25% in UV treated groups was observed with 50ug/ml crude anthocyanin fraction co administration. Presence of anthocyanins effectively reduced apoptosis in UV exposed cells when determined by fluorescent microscopy. DNA damages were ameliorated as per comet assay results. Study confirms preventive effects of Musa anthocyanin fractions on uv induced cell death and DNA damages invitro. ]]>

Granulation tissue formation is an essential phase of wound healing that occurs after inflammation. It involves the growth of new connective tissue and blood vessels, which fills the wound and forms a scaffold for tissue regeneration. In tissue engineering, biomaterials are often designed to encourage the formation of granulation tissue for faster healing. The foreign body reaction is the immune system's response to non-degradable implants or foreign materials that the body cannot eliminate. It involves chronic inflammation and encapsulation of the material to isolate it from the surrounding tissue. The foreign body reaction can be detrimental in implantable biomaterials because it can prevent proper integration and cause implant failure. Biomaterials need to be designed to minimize the intensity of the FBR to improve long-term success. Fibrosis is the excessive accumulation of fibrous connective tissue (mainly collagen) as a part of the wound healing process or chronic inflammation. It results in the thickening and scarring of the tissue, often leading to dysfunction of the tissue or organ. Fibrosis is common in many chronic diseases, including liver cirrhosis, lung fibrosis, and kidney fibrosis. In the context of biomaterials, fibrosis can prevent proper tissue integration with the implant, leading to device failure. Blood-biomaterial interactions are critical for the performance and biocompatibility of medical devices that come into contact with blood, such as stents, catheters, and heart valves. These interactions determine how the body reacts to the material, influencing inflammation, immune responses, clot formation, and the long-term success of the implant.

Key Phases of Blood-Biomaterial Interactions Protein adsorption Platelet adhesion & activation Coagulation cascade Complement system activation Leukocyte activation <img style="border:1px solid #C3E6D8;float:right;" alt="" src="https://cdn.slidesharecdn.com/ss_thumbnails/unit-1-241009141451-f15e4be5-thumbnail.jpg?width=120&height=120&fit=bounds" /> Granulation tissue formation is an essential phase of wound healing that occurs after inflammation. It involves the growth of new connective tissue and blood vessels, which fills the wound and forms a scaffold for tissue regeneration. In tissue engineering, biomaterials are often designed to encourage the formation of granulation tissue for faster healing. The foreign body reaction is the immune system's response to non-degradable implants or foreign materials that the body cannot eliminate. It involves chronic inflammation and encapsulation of the material to isolate it from the surrounding tissue. The foreign body reaction can be detrimental in implantable biomaterials because it can prevent proper integration and cause implant failure. Biomaterials need to be designed to minimize the intensity of the FBR to improve long-term success. Fibrosis is the excessive accumulation of fibrous connective tissue (mainly collagen) as a part of the wound healing process or chronic inflammation. It results in the thickening and scarring of the tissue, often leading to dysfunction of the tissue or organ. Fibrosis is common in many chronic diseases, including liver cirrhosis, lung fibrosis, and kidney fibrosis. In the context of biomaterials, fibrosis can prevent proper tissue integration with the implant, leading to device failure.

Virus means poison that are associated with death and disease. They are obligate intracellular parasites. i.e. they can reproduce or replicate only inside a host cell. They contain only one type of nucleic acid, either DNA or RNA. They lack enzymes required for protein and nucleic acid synthesis. They multiply by a complex process and not by binary fission. They are unaffected by antibacterial antibiotics. Virus can cause cancer in animals and birds, as well as in humans. Capsid Virus is surrounded by a protein coat called capsid. The capsid with the enclosed nucleic acid is known as nucleocapsid. The function of the capsid is to protect the nucleic acid from inactivation by nucleases and other deleterious agents in the environment. They also concern with introducing viral genome into host cells by adsorbing readily to cell surfaces. The capsid is composed of individual protein subunits are called capsomeres. The number of capsomeres are characteristics for a particular virus. Mainly there are 2 types of capsid symmetry – Icosahedron and Helical symmetry. ]]>

0 Sterilization Techniques - Medical Microbiology /slideshow/sterilization-techniques-medical-microbiology/271690613 sterilization-240910050543-5f2414cc
Sterilization is a critical process in microbiology that ensures the complete elimination of all forms of microbial life, including bacteria, viruses, fungi, and spores, from surfaces, instruments, and media. This process is essential in laboratory settings, healthcare environments, and industries to prevent contamination and ensure the accuracy of experimental results and the safety of products. 1. Introduction to Sterilization Sterilization is the process of making an object free from all living microorganisms, including bacterial spores, which are highly resistant to physical and chemical agents. It is a fundamental practice in microbiology to maintain aseptic conditions in laboratories, ensuring that cultures, media, and instruments are free from unwanted microorganisms that could affect experimental outcomes. 2. Importance of Sterilization in Microbiology In microbiology, sterilization is crucial for preventing contamination in experiments, which could lead to false results or the growth of unwanted microbes. It is also vital in medical settings, where sterilized instruments and environments prevent the transmission of infectious diseases. In the pharmaceutical and food industries, sterilization ensures that products are safe for consumption and free from harmful microorganisms. Physical Methods of Sterilization Heat Sterilization: The most common method of sterilization involves applying heat to kill microorganisms. This can be achieved through: Moist Heat Sterilization: Utilizing steam under pressure, as in autoclaving, to destroy all forms of microbial life. Autoclaving is widely used for sterilizing culture media, surgical instruments, and laboratory equipment. Dry Heat Sterilization: Involves exposing items to high temperatures in an oven. This method is suitable for materials that can withstand dry heat, such as glassware. Filtration: A method used to sterilize heat-sensitive liquids and gases by passing them through filters that trap microorganisms. Membrane filters with pore sizes typically around 0.22 micrometers are effective for removing bacteria and larger particles. Radiation: Uses ionizing radiation (e.g., gamma rays, X-rays) or non-ionizing radiation (e.g., UV light) to sterilize medical devices, pharmaceuticals, and food products. UV radiation is commonly used for sterilizing surfaces and air in laboratories and hospitals. 4. Chemical Methods of Sterilization Gas Sterilization: Involves using gases like ethylene oxide or hydrogen peroxide vapor to sterilize medical instruments and devices that cannot withstand high temperatures. These gases penetrate materials, effectively killing microorganisms. Liquid Chemicals: Antiseptics and disinfectants like glutaraldehyde, formaldehyde, and chlorine-based solutions are used to sterilize surfaces, instruments, and even biological materials in some cases. These chemicals work by disrupting microbial cell membranes and denaturing proteins. ]]>

Obligate intracellular, unable to self-replicate. Once inside living cells, viruses induce the host cell to synthesize virus particles. The genome is either DNA or RNA (single or double stranded). Viruses do not have a system to produce ATP. Viruses range in size from 25 to 270 nm. Viral tropism!! The classification of viruses is based on nucleic acid type, size and shape of virion, and presence or absence of an envelope. Viral Structure I . Virion is the entire viral particle. 2. Capsid is the protein coat that encloses the genetic material. 3. Capsomer is the protein subunit that makes up the capsid. 4. Nucleocapsid is composed of the capsid and genetic material. 5. The envelope is the outer coating composed of a phospholipid bilayer, which is composed of viral-encoded glycoproteins and sometimes viral encoded matrix proteins. The envelope is derived from a host cell's membrane. Some viruses use the plasma membrane, whereas others use endoplasmic reticulum, Golgi, or nuclear membranes. Naked nucleocapsids are viruses with no envelopes. ]]>

“mykos” meaning mushroom. Mycology is the study of fungi. The fungi possess rigid cell walls: Chitin and ergosterol, mannan and other polysaccharides. Beta-glucan is most important, because it is the target of antifungal drug caspofungin. Fungi are eukaryotic organisms VS bacteria (prokaryotic). The cell membrane of fungus contains ergosterol, unlike human cell membrane which contains cholesterol. Most fungi are obligate aerobes or facultative anaerobes, but none are obligate anaerobes. The natural habitat of most fungi is environment, require a preformed organic source of carbon, association with decaying matter. C. albicans is an exception!!! ]]>
