(Ashitaba) was tested for the anti-bacterial property by using the Kirby – Bauer Disk Diffusion test. There were four 25uL of Ashitaba non-polar extract with different concentrations used which were 12.5 %‚ 25%‚ 50% and 100%. In line with this‚ respective positive controls of the two specimens and negative control were also used. The results are discussed below. 4.1.1. Test against gram positive organism Triplicates of plates were used to identify the anti-bacterial property of Ashitaba non-polar

either limiting or stopping the growth of bacteria. It accomplishes this by probably interfering with the cell wall of the bacteria while having minimal effect on the normal body cells. Classifying bacteria into classes helps in identifying the bacterial species and hence they are classified as gram positive bacteria and gram negative bacteria based upon their staining techniques. Penicillin is the oldest and the best known antibiotic. Basically‚ it is an antibiotic compound derived from the moulds

Antibiotics are those that are used in the treatment and the prevention of the bacterial infections. One of the most widely used antibiotics is azithromycin. You can buy azithromycin online as it is easily available on the online drug stores. It is cheap and also in reach to the common man. All you need to know about the drug is that it is used to cure bacterial infections and also we have to make sure that we know the side effects caused by the drug. You can also tell your friends or family to buy

humans‚ termites and cockroaches. On February 6‚ 2013‚ scientists reported that bacteria were found living in the cold and dark in a lake buried a half-mile deep under the ice in Antarctica. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all‚ there are approximately five nonillion (5×1030) bacteria on Earth‚ forming a biomass that exceeds that of all plants and animals. Bacteria are vital in recycling nutrients‚ with

The antibacterial activity of natural killer cells. Introduction Natural killer (NK) cells‚ a variety of granular lymphocyte‚ are the first line of defence against infections and cancer. First identified by their ability to “naturally” kill tumour cells previously unrecognised by the host (Kiessling et al.‚ 1975)‚ these bone marrow-derived innate killers were later recognised as a sepa-rate lymphocyte lineage‚ obtaining both cytotoxicity and cytokine-producing effector functions (Trinchi-eri

of ultraviolet or visible light to excite these electrons to higher anti-bonding molecular orbitals. The more easily excited the electrons (i.e. lower energy gap between the HOMO and the LUMO)‚ the longer the wavelength of light it can absorb. Conjugation raises the energy of the bonding orbitals and lowers the energy of the antibonding molecular orbital. This lowers the energy gap and therefore means less energy is required to excite electron from ground state to excited state. Mass spectrometry:

Pharmacokinetics The pKa of Bupivacaine is 8.1. It possesses a great degree of lipid solubility and is highly protein bound. It is 14 times more potent than lignocaine. Absorption and distribution The site of injection‚ dose administered‚ addition of vasoconstrictor agent and volume of drug influences the systemic absorption of local anaesthetic. A local anaesthetic solution distributed to an area of greater vascularity leads to greater rate and degree of absorption. The final plasma concentration

Latin is an extremely important and influential language. It was the official language of the Roman Empire‚ fathered languages like Spanish and Portuguese-two of the most spoken languages in the world‚ French-lingua franca from the 17th century until the middle of the 20th and Italian-the language of the Renaissance. In fact‚ it was so influential that even today it is taught in schools though it has long been a dead language. But how did Latin become such a language? At first‚ Latin was a language

encodes this protein. You isolate this gene from the plant cell‚ clone it into a plasmid vector and amplify it in the bacterial cells. a) You decide to use the following plasmid to clone Gene A. To achieve this you digest both the genomic DNA and plasmid DNA using a restriction enzyme. You then ligate the Gene A DNA into the cut plasmids. Finally‚ you transform the E. coli bacterial cells with the ligation mix (the recombinant plasmids). Note: The recognition sites for Kpn 1 and Sal1 on plasmid
