Reaction Kinetics in the Vermicomposting Process of Peach Waste.

Peach is a fruit cultivated in temperate regions and its use generates waste composed of seeds and skin. Inadequate disposal of this waste generates an environmental impact; therefore, an alternative is to apply a vermicomposting degradation process. In this research, these four laboratory-scale reactors were used: RC (no earthworms), R1, R2, and R3 (50 earthworms each) to get mixtures in the following proportions of peach waste and load material (vegetable waste and eggshell): RC (50%-50%), R1 (50%-50%), R2 (60%-40%), and R3 (40%-60%).

The effect of the number of biopsies on the delay in the time from the delivery of mammography results to breast cancer histopathological diagnosis.

Purpose: The delay in the time (in calendar days) from the delivery of mammography results to histopathological breast cancer (BC) diagnosis could be associated with more advanced clinical stages, a worse prognosis and higher mortality. Therefore, we assessed the association between the number of biopsies and the delay in the time (in calendar days) from the delivery of mammography results to histopathological BC.

Methods: A survey was performed on 563 women aged between 35 and 69 years with histopathologically confirmed BC who attended 11 Mexican hospitals.
