A new LBBB is always pathological and can be a sign of myocardial infarction. The criteria (Sgarbossa [1]) that can be used in case of a LBBB and suspicion of infarction are: ST elevation > 1mm in leads with a positive QRS complex (concordance in ST deviation) (score 5)
Churning Out Vitamins. Your microbiota also work as vitamin-production plants. Bacteria in the gut synthesize vitamins, and those that they donât use are excreted to benefit their host. In humans, gut bacteria secrete vitamin B12 and a less familiar micronutrient called vitamin K.he resulting understanding of the microbiomeâs connections to human health may lead to a new wave of disease prevention and treatment in which very small, historically unheralded entities have big effects.
B12 synthesis is known to occur naturally in the human small intestine (in the ileum), which is the primary site of B12 absorption. As long as gut bacteria have cobalt and certain other nutrients, they produce vitamin B12. According to Dr Michael Klaper, vitamin B12 is present in the mouth and intestines.o foods naturally contain vitamin B12 - neither animal or plant foods. Vitamin B12 is a microbe-a bacteria-it is produced by microorganisms. Vitamin B12 is the only vitamin that contains a trace element-cobalt-which gives this vitamin its chemical name-cobalamin-which is at the centre of its molecular structure.
