Water Absorption of Underwater Products by Additive Manufacturing.

Rapid prototyping techniques offer significant advantages in terms of fabrication speed, accessibility, and low cost. This study explores the use of low-cost stereolithographic resins to produce prototypes intended for underwater conditions. The objective is to evaluate the feasibility of different low-cost resin brands by identifying their water absorption percentage and their response in terms of appearance and deformation after prolonged exposure to an underwater environment.

Evaluations of metabolic and innate immunity profiles in subjects with familial hypercholesterolemia with or without subclinical atherosclerosis.

Background: Familial hypercholesterolemia (FH) is a genetic condition characterized by high low-density lipoprotein cholesterol (LDL-C). The presence of risk modifiers could promote the atherosclerotic injury beyond LDL-C. Our aim was to evaluate metabolic and innate immunity profiles in FH subjects with or without subclinical atherosclerosis.

Outcomes by Retrospective Eligibility for Maintenance Therapy of Patients With Advanced Urothelial Carcinoma: Post Hoc Analysis of the Phase 3 KEYNOTE-361 Trial.

Introduction: The phase 3 KEYNOTE-361 trial of first-line pembrolizumab with or without chemotherapy versus chemotherapy alone in patients with locally advanced or metastatic urothelial carcinoma (la/mUC) completed enrollment before the approval of postchemotherapy maintenance avelumab for patients without progressive disease. This post hoc analysis evaluated the outcomes of patients who received chemotherapy alone in KEYNOTE-361 by retrospective eligibility for subsequent maintenance therapy.

Patients And Methods: Patients in the chemotherapy alone arm were retrospectively categorized as maintenance eligible (received ≥4 cycles of chemotherapy and did not die or experience disease progression within 10 weeks of chemotherapy completion), maintenance ineligible (received <4 cycles of chemotherapy or had progressive disease or died within 0-10 weeks after completion of ≥4 cycles of chemotherapy), and indeterminate eligibility for maintenance therapy (if neither maintenance eligible or ineligible).

Adhesion Properties and Pathogen Inhibition of Vaginal-Derived Lactobacilli.

In the present study, twenty-seven (27) lactobacilli strains, isolated from the vagina of healthy Italian women of reproductive age, were screened for probiotic properties. The strains were evaluated for antagonistic activity against pathogens, adhesion abilities, and potential to displace and/or inhibit the adhesion of previously adhered pathogens as a primary strain selection criterion. Overall, all the tested lactobacilli inhibited at least three pathogens, and the majority of them exhibited antimicrobial activity against Enterobacter cloacae DSM 30054, Pseudomonas aeruginosa DSM 3227, and Pseudomonas aeruginosa DSM 1117.

An indigenous microalgal pool containing Klebsormidium sp. K39 as a stable and efficacious biotechnological strategy for Escherichia coli removal in urban wastewater treatment.

Background: In recent decades the demand for freshwater has drastically increased as a consequence of population growth, economic development, climate change and pollution. Therefore, any strategy for wastewater treatment can play a role in alleviating the pressure on freshwater sources.

Results: In the present study an autochthonous microalgal pool (MP), isolated from a constructed wetland, was proposed as an alternative to the secondary treatment of an urban wastewater treatment system.
