Trimethylamine N ‐oxide (TMAO): breathe new life
Abstract Associations between an elevated level of systemic trimethylamine N‐oxide (TMAO) and an increased risk for adverse cardiovascular events have been proposed in recent years. Increasing experimental studies suggest a possible impact of TMAO in cardiovascular diseases. TMAO, the oxygenated product of TMA, is belonging to the class of amine oxides. Most of TMA derived from the bacterial metabolism of choline and L‐carnitine is absorbed into the bloodstream, and then TMA is rapidly oxidized to TMAO by flavin‐containing monooxygenase‐3 (FMO3), a hepatic enzyme. Recent years, there has been considerable interest in the role of TMAO in various pathological states. Here we discuss the biosynthesis of TMAO and emerging clinical studies that have assessed TMAO as a biomarker for various cardiovascular and other diseases such as heart failure, kidney failure, thrombosis, cancer, obesity and atherosclerosis, and diabetes. We also summarize the interaction of TMAO with synthetic and traditional molecules that together affect circulating TMAO levels.
CONCLUSION: This study confirmed published results that labour progresses more slowly as maternal BMI increases. The study was performed in a centre with a specialized BMI pregnancy clinic; thus weight gain adherence, awareness of labour differences, and patient counselling may have contributed to low Caesarean section rates. Obstetric care providers should consider differences in maternal BMI in labour progression before undertaking a potentially premature Caesarean birth, especially in primiparas.

Publication date: December 2019Source: Protein Expression and Purification, Volume 164Author(s): Elisabeth Graeber, Volodymyr M. KorkhovAbstractThe translocator protein TSPO is in an important diagnostic and therapeutic target in a range of pathologies, including neuroinflammation and cancer. Despite the availability of several structures of TSPO homologues, our understanding of the molecular determinants that govern high-affinity interactions of TSPO with its ligands is incomplete. Here, in order to decipher the key structural elements of TSPO responsible for interactions with its ligands, we designed a panel of chimeric ...
young female, known to have a metastatic breast cancer, since 5 years. In 2017, she developed secondary lesions in the brain with positive CSF. She receives 30Gy/10 fr whole brain radiation, with intra-thecal chemotherapy. A month ago, she developed gait disturbances with blurred speech an hemifacial paresia. Brain MRI showed a solitary secondary lesion, 1.5 cm involving the left middle cerebral peduncle with extensive edema. No signs of meningeal disease. Pet CT : NED outside the brain...

Ascierto, Carlo Bifulco, Giuseppe Palmieri, Solange Peters, Nikoletta SidiropoulosAn enduring goal of personalized medicine in cancer is the ability to identify patients who are likely to respond to specific therapies. Our increasing understanding of the biology and molecular signatures of individual tumor types has facilitated the identification of predictive biomarkers and has led to an increasing number of diagnostic tests to be performed, often as serial and distinct assays on limited tumor specimens. The biom...
CONCLUSION: The management of HCC in clinical practice frequently deviates from the BCLC recommendations. Most of the curative therapy options, which have well-defined selection criteria, were allocated according to the recommendations, while the majority of the palliative therapy options were assigned to patients with tumor stages not aligned with the recommendations. The only parameter which is subjective in the algorithm, the performance status, is also the least respected. PMID: 31320173 [PubMed]
CONCLUSION: We provide new evidence that TROP2 is epigenetically down-regulated and operates as a negative regulator of cell proliferation and migration in liver fluke-associated CCA. PMID: 31320172 [PubMed]
