Researchers found that microbial pathogens induce atheroma plaque formation in mice lacking anti-inflammatory cytokine IL-10. The study suggests that exposure to air-borne pathogens multiplies plaque formation by a factor of 10 in IL-10-deficient mice, making the plaque more likely to rupture.
A new compound, BP 897, has been shown to reduce compulsive drug-seeking behavior in cocaine-dependent rats. This breakthrough could lead to a new treatment for addiction, targeting the root cause of craving and compulsive behavior.
Caffeine in coffee can cross the fetal blood-brain barrier, triggering seizures in newborns. Oxygen starvation during delivery also plays a role, as it disrupts normal neuronal function.
The Ablatherm device has shown local disease control in approximately 80% of cases, with a complete response in 56% and partial response in 24%. The treatment is minimally invasive and can be repeated if necessary, but may have some adverse effects.
Researchers identified five brain areas activated during sexual arousal, including the inferior temporal cortex and right orbitofrontal cortex. The study used positron emission tomography to map brain activity while subjects watched different films, providing insights into the neurophysiological bases of human sexuality.
The INSERM Collective Expertise Report on Migraine emphasizes that paramedical examinations are unnecessary for diagnosis, recommending a simple interview and medical examination instead. Effective treatments exist, but patients often underestimate their benefits, and confusion between triggers and underlying causes persists. The repor...
A new assay method has been developed to measure chromogranin A in peripheral blood, allowing clinicians to follow the outcome of gastrointestinal neuroendocrine tumors. This method could also serve as a diagnostic marker for other types of neuroendocrine tumor, such as small-cell lung cancer in smokers.
Mutations in the beta-catenin gene are frequent in hepatocellular carcinoma, a type of liver cancer. The study found that about 50% of tumors in transgenic mice contained these mutations, and 26% of human liver cancer samples also had similar genetic alterations.
Fibrates, used for decades to treat hyperlipidemia and atherosclerosis, have been shown to reduce inflammation in vascular muscle cells, inhibiting the production of pro-inflammatory cytokines. This mechanism suggests that fibrates may have a beneficial vascular action during atherosclerosis treatment.
A European epidemiological study found a weak but significant association between certain factors and sporadic CJD, including consumption of raw meat or brain tissue. The researchers noted that the study is only a first step and many questions remain to be answered.
Researchers found that heterozygous children with the delta 32 mutation experienced slower disease progression and delayed onset of severe immunodeficiency. This discovery provides important arguments for the beneficial effect of delta 32 heterozygosity on HIV disease progression in children.
Researchers identified a novel gene, Doublecortin, involved in cortical development and associated with severe forms of epilepsy and mental retardation. The gene is linked to the X-SCLH/LIS syndrome, which affects brain structure and function.
Researchers have identified the genetic link to Griscelli disease, a rare autosomal recessive disorder characterized by partial albinism and immunologic abnormalities. The gene responsible for the condition is myosin-5a, which plays a crucial role in organelle transport within cells.
A new oral vaccine approach is being developed to protect pancreatic cells and prevent the autoimmune disease type I diabetes. Early trials have shown promising results using a combination of insulin and cholera toxin.
