Metagenomics is a discipline that enables the genomic study of uncultured microorganisms.Faster, cheaper sequencing technologies and the ability to sequence uncultured microbes sampled directly from their habitats are expanding and transforming our view of the microbial world.Distilling meaningful information from the millions of new genomic sequen
Introduction: Acquired broncho-esophageal fistulas are uncommon and typically malignant in origin.Because of their location, they are difficult to treat and involve complicated repairs with equivocal results.Prior treatment with self-expanding Insulation stents when not successful, makes the management even more complicated.Patients and methods: In
In Arabidopsis thaliana, lateral roots (LRs) initiate from anticlinal cell divisions of pericycle founder cells.The Washing Machine Timer formation of LR primordia is regulated antagonistically by the phytohormones cytokinin and auxin.It has previously been shown that cytokinin has an inhibitory effect on the patterning events occurring during LR f
The p53 tumour suppressor is the most frequently mutated gene in human cancer.This transcription factor can be activated by diverse cellular stresses, including DNA damage and oncogene activation.Through transcriptional induction of appropriate target genes, p53 can stimulate activity in a broad range of effector pathways, most notably cell cycle a
This article provides a historical account of the discovery, chemistry, and biochemistry of two ubiquitous phosphoglycerolipids, phosphatidylserine (PS) and phosphatidylethanolamine (PE), including the ether lipids.In addition, the article describes the biosynthetic pathways for these phospholipids and how these pathways were elucidated.Several uni
