Vertebrates also show behavioral signs when pain is induced, including facial contortions, writhing, moaning, forms of calling, and moaning in attempts to avoid that specific source of pain or attract attention in order to receive help. According to The New England Anti-Vivisection Society, The Animal Welfare Act (AWA) is the only U.S federal law that covers animals in research. This law regulates the use of vertebrates in research as well as their care, testing, exhibition, teaching, and…

Cell penetrating peptides are proteins or peptides that typically consist of 5-30 amino acids. These peptides are unique in that they are able to cross cell membranes and other barriers throughout the body such as the blood brain barrier, intestinal and nasal mucosa, and even skin. Using CPPs, scientists are now able to explore their potential as a means of transporting cargo into cells and across bio barriers. With their ease of preparation and generally nontoxic nature, CPPs have gained a…

“I don’t know” I can still distinctly recall my eleven-year-old self repeatedly saying to anyone who tried to talk to me. It was my first day of school in America and that was the only sentence I could put together in English. I was born in China and lived there my whole life until my mother decided to move to New York. I thought I was just visiting her for winter break, but she dropped me off at school just a week after my arrival. As my new classmates tried to talk to me, I can see their…

This book “Cryptic Female Choice in Arthropods” provides a comprehensive and up to date look into research from the last few decades on Cryptic Female Choice (CFC) in arthropods. This book is built around research from a variety of experts in the field who together build a book structured around key behavioural, ecological and evolutionary questions in regards to specific taxonomic groups of arthropods, such as, spiders, harvestmen, flies, moths, crickets, earwigs, beetles, eusocial insects…

The Essentialism Perspective on Promiscuity and the Societal Repercussions Throughout western history, there has been one main belief that has prevailed regarding men and women’s sexuality: that sexual motivation is influenced by the physiological differences between the sexes and accounts for their variances in behavior. This essentialism approach to sexuality, developed with the advancement of evolutionary psychology, which states that all living things maintain a fixed biological,…

Sirtuins and Histone deactylases (HDACs) Eukaryotic DNA is packed in a high level structure called chromatin, resulting from the assembly of an elementary unit, the nucleosome, and an octameric structure obtained from eight proteins called histones [1]. Histone deacetylation is a reversible process whereby histone and non-histone protein transfer the acetyl moiety from acetyl co-enzyme A (CoA) to lysines while histone acetylation is the direct opposite process whereby acetyl groups are removed…

Preparing Subcultures. We obtained a stock vial with hot cheeto and a stock vial of wild type Drosophila melanogaster. We began our study of hot cheeto, a bristle mutation, by setting up subcultures of the mutant. We used the hot cheeto stock to create a new subculture to collect virgin females to be used for the genetic crosses. To reduce the chance of infection when creating subcultures, we disinfected the workplace station with a solution of 70% ethanol. Flies were anesthetized using the…

Charbill Klayme 0993551 Dr. Hye-Jeong Yeo Functions of SREBPs Abstract SREBPs are 1,150 Amino Acid long proteins that are used to activate cholesterolgenesis. SREBP-1a are used to induce all the response genes. The SREBP-2 are used to allow expression of the LDL receptor. Ubiquination, usually by the kinase GSK3, can be the weapon to destructing SREBPs. SREBP-1a will build more cholesterol and fatty acids in rats and mice when it is over expressed. The SREBP-1c are best studied in the…
