The study also revealed sex-based differences in workplace conflicts, with men more likely to complain about conflict in Finland.
Researchers at The Chinese University of Hong Kong have identified biomarkers in preterm infants' blood that can detect late-onset septicemia and necrotizing enterocolitis. These findings may help diagnose preterm infants requiring urgent treatment, reducing the risk of life-threatening conditions.
A new study suggests that the extinction of woolly mammoths and other large mammals may have been triggered by the addition of a predator: humans. The researchers argue that human hunters provided new competition for major predators, leading to a trophic cascade that ultimately caused the decline of herbivores and carnivores alike.
Research on Palestinian women who have given birth multiple times found a significant association between parity and increased risk of metabolic syndrome, obesity, and high blood triglyceride concentrations. The study suggests that any of these factors alone or in combination can increase the incidence of coronary heart disease.
Researchers found that mesenchymal stem cells can triple survival rates in an experimental model of sepsis, a deadly condition caused by infection. The treatment also reduced inflammation and improved organ function in mice with severe sepsis.
