G6PD Deficiency

Quite likely the single biggest piece of good news about G6PD deficiency is that it is widely understood to confer protection against malaria, in particular the most deadly form of that disease - Randall Amster


Our mental state is governed in large part by a unique cocktail of neurotransmitter chemicals in the brain—one of which is GABA (gamma-aminobutyric acid). GABA is essentially your body's "calm down" signal, pumping the brakes on overexcited neurons, contributing to an overall relaxing effect - Stephanie Eckelkamp


Gabapentinoid drugs—specifically gabapentin (Neurontin) and pregabalin (Lyrica)—are increasingly being prescribed for pain because physicians and patients seek alternatives to opioids in the midst of the opioid crisis. However, such widespread and often indiscriminate prescribing of gabapentinoids is not supported by robust evidence - Christopher W, Goodman MD

We are a product of genes and the influence of life - Tamerlan Kuzgov

Genetic Cancer Testing

The tests, which look for minuscule shards of cancer DNA or proteins, are a new frontier in screening. Companies developing them say they can find dozens of cancers. While standard screening tests are commonly used to detect cancer of the breast, colon, cervix and prostate, 73 percent of people who die of cancer had cancers that are not detected by standard tests - Gina Kolata

Geneticist Organizations

The genes are the atoms of heredity - Seymour Benzer


Genetics play a huge part in who we are. But we also have free will - Aidan Quinn

Genetics & Cancer

The understanding that genetic mutations are linked to cancer is decades-old; the first human oncogenes (genes that trigger cancer) were found in the early 1980s. The exponential growth of cancer genomics is the legacy of the Human Genome Project and spin-off projects like the Cancer Genome Atlas, a publicly funded, collaborative project to parse the genetic underpinnings of cancer, as well as technological advances that allow rapid extraction of genetic information - Jessica Wapner

Geodon (Ziprasidone)

As it's not a conventional antipsychotic like haloperidol (Haldol), it doesn't function solely through dopamine antagonism but also affects serotonin pathways. This varying mode of action means its side-effect profile differs from typical antipsychotics, particularly in that it's less likely to cause extrapyramidal symptoms such as tremors or stiffness - common side effects with drugs like Haldol - Power


As the threat of global warming grows more urgent, a few scientists are considering radical—and possibly extremely dangerous—schemes for reengineering the climate by brute force - Graeme Wood

Glioblastomas are characterized by extreme genomic instability, even by the standards of cancer cells, meaning that what appears to be a single tumor is almost certainly a large collection of different cell types using different mechanisms to grow and survive. That explains why no single therapy has had much success in the field - Derek Lowe

Gliptins DiPeptidyl Peptidase-4,Inhibitors

Gliptins are accepted as a standard therapy for diabetes mellitus today. By inhibition of the enzyme dipeptidyl peptidase 4 (DPP4), gliptins prolong the GLP1-dependent insulin secretion in the pancreatic β-cells - Friederike Remm

When you or someone you know is diagnosed with celiac disease or a gluten intolerance you might think that life as you know it is over. There is a saying, diets don't work but the Gluten-Free diet may - Stacy Matson

Gluten Free Grains

Lingering confusion surrounding these grains may stem from outdated information still available on the web and in cookbooks written several years ago. While the grains millet, sorghum, amaranth, buckwheat, and quinoa are now generally accepted as safe for persons with celiac disease, this hasn’t always been the case - Tricia Thompson MS RD

Gluten Grains

Luckily, however, only a few grains are truly glutinous: wheat, spelt, rye, barley, and, in some cases oats, due to agricultural cross-contamination - Sara Moulton

Gluten Intolerance

There’s been public debate as to whether or not gluten sensitivity is a real condition or just some sort of uniform delusion manifested in hypochondriacs and picky eaters - Samantha Olson

Colorless and odorless, glycine (or aminoacetic acid) is the simplest amino acid found in nature because of its single hydrogen side chain. But its functions are anything but simple - Jamie Witherby

Gonorrhea Treatment Guidelines

Monotherapy with IM ceftriaxone is recommended for all patients with gonorrhea, including pregnant patients. If co-infection with chlamydia has not been excluded, add doxycycline 100 mg po bid x 7 d for non-pregnant persons or azithromycin 1 g po x 1 dose for pregnant persons - CDPH

Grains & Carbohydrates

“Nobody should eat grains; they all have a high glycemic index, especially pasta.” If you’ve heard — and believed —statements like these, the truth may surprise you: many grains have a very low glycemic index – including pasta.
