Telomerase reverse transcriptase

Results A total of 926 bands were scored of which 96 were polymorphic (Table1). The number of bands per primer varied from 43-145 and a minimum of 43 bands were generated with primer KITT-17 while the maximum of 145 bands were scored with OPA-01 (Fig.1) and OPA-12 respectively. RAPD analysis (Henry 1997) and Jaccard's coefficient similarity varied from 0.125-0.792. The highest Jaccard's coefficient similarity (0.792) was observed in BSMR20Krb, while the lowest similarity (0.125) was observed

Mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) accounts for nearly all new infections in young children around the world1. Although the incidence rate of HIV has declined in most parts of the world over the last 15 years, the World Health Organization (WHO) estimates that in 2015, more than 1.4 million pregnant women globally lived with HIV.2 Without treatment, an HIV-positive pregnant woman has a 30-35% risk of transmitting the infection to her child3. USAID estimates

Reverse transcriptase polymerase chain reaction, also known as RT-PCR, has been recognized as a reliable, accurate, and sensitive method for quantifying gene transcription. Polymerase chain reaction, also known as PCR, is considered an essential tool in molecular biology that allows for the amplification of nucleic acid sequences. Specifically, the three main consecutively repeating steps in PCR are denaturation, annealing, and elongation. If the reaction runs with 100% efficiency, there will be

Case Introduction This case study focuses Burroughs Wellcome and their drug Retrovir. Retrovir is a drug that treats AIDS and AID-related complications. In 1987, Burroughs Wellcome obtained approval from the FDA to market azidothymidine (AZT), also known as Retrovir, as a treatment for AIDS. Retrovir was the only kind of drug on the market. Because of this, many critics accused Burroughs Wellcome of price-gouging, as the price of Retrovir was $188 for a hundred 100mg capsules sold to wholesalers

An epidemic is sweeping the nation. Rapidly more cases of STD’s are being noted to appropriate health officials and are steadily increasing instead of declining. The Centers for Disease Control, commonly known as the CDC, have vigorously tracked HIV numbers and an estimated “1,218,400 persons aged 13 years and older are living with the HIV infection” (“HIV in The United States: At A Glance”). This doesn’t include the amount of people clueless to being infected at all: a whopping 156,300. Discouragingly

carried out in 50 µL reaction mixture using QIAGEN OneStep RT- PCR kit (Qiagen,Ca). RT-PCR was carried out using a thermal cycler (T100 thermal cycler, Bio-Rad) to amplify cDNA fragments using the following conditions: RT at 50 °C for 30 min for reverse transcription followed by initial PCR activation for 15 min at 95 °C; 40 cycles of PCR, with each cycle at 94 °C for 60 s, 52 °C (while using PMTV2F and PMTV3 R)or 57°C ( while using C819 and H360 ) for 60 s, and 72 °C for 60 s; and a final extension

cell. Once an entry is initiated and completed, HIV has the ability to replicate into thousands of copies of itself by using the host cells resources and the RNA. The RNA, which is two stranded, converts into DNA through an enzyme titled reverse transcriptase. When the DNA is set within the host’s genome, it allows replication to occur. Furthermore, the new viral copies are made and the host cell ruptures and dies. As a result, the multiple viruses are released and continue to infect more of

Real-time PCR detection of HIV viral load Introduction: HIV, the Human Immunodeficiency Virus is a lentivirus which is responsible for HIV infection and eventually causes AIDS. It’s assumed that the virus has been in existence since 1930 but it’s still unclear that how the virus came into existence. There are two kinds of HIV virus, HIV-1 which causes more severe disease and the source of transmission is a chimpanzee species Pan troglodytes whereas HIV-2 is transmitted by Cercocebus atys, a monkey

replicate its own genome (Freeman, 2011). Viruses have either a deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) genome that affects its specific named genome. Types of RNA viruses include positive strand, negative strand, double strand and RNA transcriptase. RNA viruses have evolved into effective pathogens that mutate at high rates. This allows them an advantage over their host to effectively evade the immune system through several mechanisms, such as mimicry, avoiding cell lysis, and phagocytosis
