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.
To produce PHA, a culture of a micro-organism such as Alcaligenes eutrophus is placed in a suitable medium and fed appropriate nutrients so that it multiplies rapidly.Once the population has reached a substantial level, the nutrient composition is changed to force the micro-organism to synthesize PHA.HA synthases are the key enzymes of PHA biosynthesis. They use the coenzyme A-thioester of (r)-hydroxy fatty acids as substrates. The two classes of PHA synthases differ in the specific use of hydroxy fatty acids of short or medium chain length.
