Plants are not exposed to herbivores without defenses. When an insect feeds on a leaf, thereby wounding it and releasing oral secretions, a signaling cascade is elicited in the plant, usually starting with a rapid increase in the amount of the plant hormone jasmonic acid and its active isoleucine conjugate. Jasmonic acid regulates various reactions in plants, including defenses against herbivores and responses to environmental stress. Mutants with disadvantageous properties do not necessarily disappear An important thesis of evolutionary theory is natural selection and the conclusion that mutants with disadvantageous properties disappear ...

With opioid overdose deaths surging in the United States, many communities are in desperate need of solutions to bring down the body count. Among the most promising is strengthening prison reentry programs for highest-risk users, a Rutgers-led study has found.   “For people who use drugs and have been in prison for several years, the reentry period can be chaotic and disorienting,” said Grant Victor, an assistant professor in the Rutgers School of Social Work and lead author of the study published in the Journal of Offender Rehabilitation.   “Closing ...

The COVID-19 pandemic dealt a huge blow to healthcare systems and highlighted their major shortcomings. As of June 2023, there have been over 760 million confirmed cases of COVID-19, with almost 7 million deaths worldwide. During the major COVID-19 outbreaks, hospitals often had their intensive care units (ICU) running at full capacity for providing invasive mechanical ventilation to patients who were diagnosed as positive for COVID-19. These ICUs often operated with insufficient staff and intubation equipment. One way to mitigate such problems is to accurately predict the prognosis ...

Research Highlights: An analysis of a clinical trial of more than 2,500 people with Type 2 diabetes and kidney disease found that high levels of four biomarkers are strongly predictive for the development of heart and kidney issues. People who took canagliflozin, a sodium glucose co-transporter 2 inhibitor (SGLT2 inhibitor), had lower levels of the four biomarkers compared to those who took a placebo over the three-year study period. Treatment with canagliflozin helped to substantially reduce the risk of hospitalization for heart failure and other heart complications among patients considered to have the highest risk.

Alcohol consumption is a significant risk factor for gastrointestinal diseases, including cancer. Alcohol can damage the gastrointestinal tract in several ways. It can promote an impairment of several intestinal barrier functions, leading to leaky gut and dysbiosis. Ethanol metabolism can also produce toxic substances such as acetaldehyde and acetate, further damaging the gut and potentially promoting cancer.  Ethanol and its metabolites enhance DNA damage response and dysregulate the epithelial proliferation/differentiation program, thereby increasing the risk of cancer development. In a new paper published in eGastroenterology, ...

#FRANKFURT. Immediately after the infection of a cell in the throat or lungs, the SARS-CoV-2 virus works very hard to replicate, using the human cell’s metabolic pathways to produce its proteins and make sure that its genetic material (the RNA genome) is copied. The RNA genome is then packaged very compactly into new virus particles that are released from the cell to infect more cells. One viral protein, called the nucleocapsid protein (N), is particularly important for rapid and efficient replication. ...

Applying ground-up silicate rock to Midwestern farm fields can capture significant amounts of carbon dioxide and prevent it from accumulating in the atmosphere, according to a new study that successfully quantified those climate benefits for the first time. Working with Eion Corp., researchers at the University of Illinois Urbana-Champaign and the Leverhulme Centre for Climate Change Mitigation (LC3M) developed a new method to calculate the CO2-reduction potential of basalt rock amendments applied to cropland soil, a process known as enhanced weathering. Traditional row-crop agriculture releases sizable amounts of soil-derived carbon to the atmosphere as CO2, a greenhouse gas ...
