Incubation period

Bubonic plague is the most common form in humans. After exposure to the plague, such as through a bite from an infected flea or rodent, there is a 2-8-day incubation period during which the bacteria travel to the local lymph nodes. Symptoms include sudden fever and chills and bubo formation at the affected lymph nodes. The buboes, which are tender and warm, grow quickly in size and destroy the lymph node. From the…

Sleep Insight Improves Memory Recall It is common knowledge that sleep is essential for survival, “we spend about one-third of our lives asleep.” (National Institutes of Health, 2003) When an individual obtains adequate sleep, it is known to lower stress, improve one’s mood, help maintain a healthy weight, improves athletic performance/coordination, and increases one’s ability to pay attention and remember new information. The benefits of getting adequate hours of sleep, in turn have drastic…

Varicella Zoster Virus (VZV) is a member of the Herpesviridae family, that causes two different infections: varicella and herpes zoster. This paper will include information on the history of Varicella Zoster Virus and how to treat it. Most people know varicella as chickenpox, which is a modified version of the previous term: chicken peas. It was previously called chicken peas because the red rash that appear resembles the vesicles of chickpeas (garbanzo beans) or chicken pecks. Red, itchy spots…

Children are curious little people who find a way of sticking anything and everything in their mouths before their parents can even get a chance to say “NO!” This is one of the main reasons why they are always getting sick and occasionally infecting the people they are in close contact with. The well-known hand-foot-mouth disease is almost always seen in children under the age of ten because of how infectious it is. Unfortunately hand-foot mouth disease is not limited to children. My cousin,…

Centers for Disease Control and Prevention states that, “Communicable disease means- an illness caused by an infectious agent, or its toxins, that occurs through the direct or indirect transmission of the infectious agent or its products from an infected individual or via an animal, vector or the inanimate environment to a susceptible animal or human host”( CDC, 2012, p.1). The main goal is to prevent the spread of the disease to the health care and into the community by breaking the chain and…

The SH-SY5Y neuroblastoma cell line was procured from National Centre for Cell Sciences, India and maintained in (DMEM) (Sigma Aldrich, USA) and Ham 's F12 nutrient mixture (F12) (Sigma Aldrich, USA) in 1:1 ratio. The medium was supplemented with 2 mmol L-glutamine (HiMedia, India), 10% (v/v) heat inactivated fetal bovine serum (FBS) (Hyclone Laboratories, Logan, UT) and 1% antibiotics (penicillin/streptomycin). Cells were cultured at 37 ºC in a humidified CO2 ¬incubator containing 5% CO2 and…

Plasmid Injection on Prokaryotic Gene Expression. By Kush Patel 3rd Period, AP Biology, February 12, 2024. Lab Partners: What is the difference? Brody Bonsor Andrew Zhang Marianne Baquero Clarie Gabrielson Abstract: In the pGLO lab, E. coli bacteria were genetically modified using a plasmid that contained three key genes: araC, GFP, and ampicillin resistance. Through a process of heat shock and incubation, the pGLO plasmid was successfully introduced into the bacteria. This…

The problem with gull population control is that gulls tend to live long lives, so they do not need to produce many offspring in order to maintain a stable population. For control methods to have the desired effect they have to be widespread for a period of time to truly impact the population numbers (Saunders,…

Emily Astarita, Amelia Grose, Natalie Krapcho and I’s project is titled “Concentration Quantification and Comparison with the HIC Eluate and Bacterial Lysate.” The overall objectives of this experiments include using a spectrophotometer to obtain absorbance of standard solutions to create a standard curve from this data, and subsequently using the equation of the curve to find the concentration of GFP elute which was purified from the column. Using the spectrophotometer to create a standard…

Article 1 1. The question the researchers are trying to answer is whether or not the time of year has an impact on the reproductive capabilities of a male Siberian tiger. The researchers want to know if the time of year has an effect on how much sperm the male tigers are able to create and the quality of their sperm production. They predicted that the female tigers were the only ones whose reproductive system was affected by the time of year and that the males would show no variance, this was…
