The Efficacy of a Mix of Probiotics ( LMG P-27481 and GG ATCC 53103) in Preventing Antibiotic-Associated Diarrhea and Infection in Hospitalized Patients: Single-Center, Open-Label, Randomized Trial.

Background: Antibiotic-associated diarrhea is a condition reported in 5-35% of patients treated with antibiotics, especially in older patients with comorbidities. In most cases, antibiotic-associated diarrhea is not associated with serious complications, but it can prolong hospitalization and provoke infection. An important role in the prevention of antibiotic-associated diarrhea is carried out by some probiotic strains such as or the yeast that showed good efficacy and a significant reduction in antibiotic-associated diarrhea.

Evaluation of the PMMA microlens efficiency for the realization of a solar micro-concentrator array.

In order to assess the performance of solar micro-concentrators, specific methods and protocols need to be developed, tested, and applied. In detail, as in conventional concentration modules, one of the fundamental parameters to consider is the efficiency of optical concentrators. In fact, optical concentrators give fundamental information on the current potentially generated from solar microcells that receive the concentrated light radiation.
