The return of malaria to India

Chemical genetics involves the substitution of a gatekeeper residue with an amino acid containing a different side chain at the target locus. Here, we have generated a mutant parasite containing a hypomorphic allele of cdpk1 and identified compensatory pathways adopted by the parasite in the mutant...

This video describes india ink inflation--a staining method--to quantify tumor nodules in tumor-bearing mouse lungs. After staining, the lungs are fixed in Fekete's solution to observe tumor nodules in the...

In this interview, George Dimopoulos focuses on the physiological mechanisms used by mosquitoes to combat Plasmodium falciparum and dengue virus infections. Explanation is given for how key refractory genes, those genes conferring resistance to vector pathogens, are identified in the mosquito and how this knowledge can be used to generate transgenic mosquitoes that are unable to carry the malaria parasite or dengue...

Anopheles stephensi mosquitoes are vectors for malaria inhabiting India and throughout Asia. This video demonstrates the technique for performing microinjections of this species with transgenes that will confer resistance to the malaria to the mosquito. Much of the methodology demonstrated in this video is applicable to microinjection techniques of other mosquito...

The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Returns in a financial context refer to the change in the value of an asset, investment, or project over a specified period. They measure an investment's profitability, which can be either positive or negative, representing profit or loss. Understanding returns is fundamental for investors as it helps them evaluate their investments' performance and make informed decisions about where to allocate their capital to maximize gains.
The calculation of returns involves comparing an...
