Abstract: A method for diagnosing chronic kidney disease (CKD), including measuring an expression level of each microRNA (miRNA) of first miRNAs in a biological sample of a subject and comparing the expression level of each miRNA of the first miRNAs with a respective reference level corresponding to each miRNA of the first miRNAs.

In one embodiment, a bioreactor has two compartments containing three cooling plates. These plates have internal baffles instead of cooling tubes. The bioreactor has temperature sensors are loaded at different heights of the outer cooling plates for recoding and monitoring bed temperature during fermentation. Short space between two cooling plates with suitable material construction permits metabolic heat removal by conduction. The distance between two compartments is adjustable manually to achieve the best width. The product is extracted and harvested in the bioreactor using a trickle solvent. All of the on-line data are monitored on screen and recorded in the computer. Microorganisms are cultivated in such a manner that the bioreactor carries out all steps for cultivating microorganisms in an aseptic environment.
