In vitro fertilisation

Introduction: Imagine being told that you were not able to conceive because you are infertile. How would that make you feel? For most, that would make them feel discouraged. There is a technology in science now called in vitro fertilization (IVF) that could help with this issue. IVF can help the 10% of couples who have issues conceiving (Van Voorhis 2007). These couples in most cases have tried for years to have a child. The use of this technology is not always supported, because it does present…

Nano-dots in Mammalian Gametes Imagining1 The Nano-dots, or Quantum Dots (QD), are nano-scale semiconductor devices with diameter up to 10nm, which were first discovered in 1980s2. Once stimulated, they give emission of light with specific colours, which is then visualised1-3. These nano particles have high size-tunability, once illuminated, different emission wavelength can be obtained by manipulating the size of dots3. Inorganic QDs are made up of two components, an atom-cluster core with…

The term artificial insemination can be identified as the procedure in which a female animal is fertilized by humans using methods other than the natural fertilization methods. In agriculture, especially the industrial sector, the principal of artificial insemination is extremely important to the business in all types of animal based agriculture from large ruminants like cows to chickens. Artificial insemination is important, in the industry, because of factors such as genetic variation,…

Animals all over the globe are sitting in a cage right now, scared, cold and alone waiting for the next experiment to be done to them. They sit in this cage longing for the day that they are able to free, if they survive the experiments or if they are of no longer need to the scientists. Every year there are millions of animals killed in laboratories from the tests and experiments done to them. These poor, defenseless animals are poisoned, shocked, and burned during these tests and are often…

peucetius and functionally characterized. Moreover, its biotechnological application for the production of diverse classes of O-methoxy natural products was experimented and investigated. Among these substrates both in the in vitro and in vivo bioconversion experiments, 7,8-dihydroxyflavone showed significant product conversion and was further analyzed by NMR study and confirmed as 7-hydroxy 8-O-methoxyflavone. Fermentation bioconversion assay was also performed with 7,8-DHF…

suffering just for answers? Also some animals are put in cages until needed says Nick News. Finally, animal testing is not necessary. For example there is such things as a chip that represents a human cell. There are also other options, one called the in Vitro method. Next, the last method is the Silico method. There are other alternatives to animal testing and people should take advantage of…

Aim 3. Validation of transcriptional drivers and therapeutic combinations in CRPC. Rationale and strategy: To experimentally validate computationally predicted drivers of CRPC, we will use loss- and gain-of-function approaches for in vitro (i.e., cell lines) and in vivo (i.e., xenograft models) experimental validation to determine whether these genes are essential for drug-resistance. Computationally inferred drug combinations will be validated for their effect on MRs’ activity and ability to…

Introduction Sea urchin gametes are an excellent model for observing vertebrate development. Sea urchins are a low cost species that can be maintained in a laboratory environment, have external fertilization and have distinct stages for viewing development in offspring. They are external breeders, so when the gametes are mature, they are released into seawater. The seawater carries the gametes where they will fertilize and develop. How does the sperm find the eggs? The jelly coating on the…

Tests determining genetic toxicity such as the chromosome aberration test costs $30,000 while an in vitro test only costs $20,000. iii. Embryotoxicity tests performed on rats cost $50,000 while the in vitro rat limb bud test costs $15,000 [4]. V. Animal testing is cruel and inhumane. a. Animals involved in experiments undergo a lot of suffering. They may be purposefully infected with deadly diseases…

Meat of the Future As the science we know today’s advances, many things are being developed. One of these things are advancement of engineered meat. Within the last decade, scientists have been looking for a solution to create meat without it coming directly from animals. Pushing the boundaries of science have also been exhibited in Mary Shelley's book Frankenstein; in this book Shelley gives a theory of bringing a new creature from other parts of a deceased creature. Making lab-produced meat is…
