A global problem according to the WHO, sepsis serves as an indication of a health system’s low bed availability in ICUs and lack of preventive measures regarding hospital infection. A study considering Brazilian ICUs understands that investments in intermediate-care units can reduce the incidence of sepsis among in-patients. …read more Source: EurekAlert

Adult males of are a deep reddish-orange, while females and juveniles are pale yellow, according to the authors of an article in Journal of Fish Biology describing tetra Hyphessobrycon myrmex. Scientists integrate a Brazilian research project on fish which belongs to Characiformes order living in the headwaters of Amazon rivers, regions whose fluvial biodiversity is potentially threatened by projects for hydroelectric plants. …read more   Source: EurekAlert

Physics manuals have considered niobium boride to be superconductive for more than six decades. In a study conducted by American and Brazilian scientists, scanning electron microscopic analysis showed the material presents two distinct crystalline phases, being that superconductivity is restricted to the minority phase. The discovery paves the way for technological applications of other superconducting materials. …read more   Source: EurekAlert

Screening used synthetic compound similar to curcumin (a pigment extracted from turmeric), which displayed anti-tumor action in preliminary tests. Next step will be evaluating these genes’ roles on tumoral progression and exploring them as therapeutic targets – melanoma is the most lethal and also the most chemotherapy-resistant type of skin cancer. …read more Source: EurekAlert

Brazilian scientists investigate tumoral development caused by benzo[a]pyrene, a hydrocarbon present in cigarette smoke, automotive exhaust, burnt wood fumes and barbecued meat

Brazilian scientists show that parasite’s penetration of host cells increases expression of certain microRNAs capable of inhibiting action of immune system. …read more Source: EurekAlert

Carbohydrates, which have been progressively employed in intensive breeding, induces the fermentation that leads to the development of acidosis, the second most important health problem in feedlot cattle according to nutritionists. Scientists test additives on the feed capable of controlling the bacteria involved in fermentation. …read more Source: EurekAlert

In experiments with mice, a Brazilian research group showed that, well before the profile of intestinal bacteria gets altered, a diet rich in saturated fats damages the hypothalamus — region of the brain responsible for optimizing the organism’s absorption of nutrients — because its cells react to the excess of fat in the bloodstream as if they were fighting pathogens. According to the research, the ensuing process of inflammation and methabolic disbalance can recede through a diet with [...]
