HOUSTON ― Researchers at The University of Texas MD Anderson Cancer Center have discovered that lactate-producing intratumoral bacteria drives resistance to radiation therapy,  suggesting that lactic acid-producing bacteria present in various cancers may serve as novel therapeutic targets. The study, published today in Cancer Cell, reported that a particular bacterial species, Lactobacillus iners (L. iners), caused cancer cells to respond to radiation by rewiring metabolic signaling pathways to resist treatment. The researchers also found that L. iners was associated with poorer clinical outcomes in patients with cervical ...

While the overall incidence and death rates from cervical cancer have dropped in the U.S., the opposite has been occurring in Appalachian Kentucky – a steady increase. The death rate from cervical cancer in Appalachian Kentucky is now twice that of the national rate. A team of cancer population scientists from MUSC Hollings Cancer Center and the University of Kentucky Markey Cancer Center documented the increase through investigation of county-level data from 2000 through 2019. Their findings are published this month in JAMA Network Open. “The rapidly growing disparities that we're ...

Controlling the process of destabilization is important when manipulating the unfolding and refolding of proteins in vitro (outside their native environment). To this end, urea and alcohol are used as cosolvents, substances added in small amounts along with water, to destabilize and denature proteins. Urea disturbs a native protein to produce disordered coils, and the interference by alcohol treatment yields helical structures. Research on the mechanism of cosolvents has shown that a protein’s stability between its native and denatured states is tied ...

Hook-ups where one partner is drunker than the other are more likely to be seen as assault, researchers at the University of Essex revealed.       A study by Dr Veronica Lamarche, from the Department of Psychology, discovered equal consumption was more important than levels of drunkenness.      This was the case even when couples had drunk to excess and was the same across sexualities and genders.       Dr Lamarche discovered that romantic rendezvous were seen most positively when couples drank the same low level of alcohol.      And encounters where one partner was ...

(WASHINGTON, Oct. 19, 2023) – Patients with multiple myeloma treated with idecabtagene vicleucel, known as “ide-cel,” a chimeric antigen receptor (CAR) T-cell therapy, had no difference in overall survival outcomes regardless of race and ethnicity, according to a study published in Blood Advances. “With this study, we see that Black and white patients with multiple myeloma both respond well to ide-cel,” explained Laura Peres, PhD, an epidemiologist at Moffit Cancer Center and the study’s lead author. “We hope that these findings encourage the use of ide-cel ...

Biodiversity is essential for sustaining food security, livelihood, ecosystem health, and economic development and for preventing future epidemics. Asia, with nearly 60% of the world's population, stands out as a priority for urgent biodiversity conservation due to its large threatened species and protected areas (PAs), and many countries globally are facing extreme biodiversity and ecological threats. Satellite observations have shown that the human activities (i.e., cropland and artificial surface creations) in Asia have rapidly expanded since the 21st century and are being expanded to highlands (hilly and mountainous regions). Obviously, the intensification of human activities ...

Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, University of Copenhagen researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish. Yuk! Musty, earthy or muddy-tasting fish is never going to go over well with the family. Perhaps you’ve tasted it in trout caught from a put-and-take pond. The off-flavor ...

Highlights: High blood pressure affects a large share of the global adult population. Previous studies suggest probiotics may help prevent hypertension.
