Sustainable and biodegradable polymer packaging: Perspectives, challenges, and opportunities.

The escalating environmental impact of non-biodegradable plastic waste has intensified global efforts to seek sustainable alternatives, with biodegradable polymers from renewable sources emerging as a promising solution. This manuscript provides the current perspectives, challenges, and opportunities within the field of sustainable and biodegradable packaging. Despite a significant market presence of conventional non-biodegradable petrochemical-based plastics, there is a growing trend towards the adoption of bio-based polymers from renewable resources driven by environmental sustainability and regulatory measures.

Peritoneal histopathological changes and cultures after autogenous fecal peritonitis induced in elderly rat model: response to intravenous use of meropenem and intra-abdominal inoculation of 10% aqueous extract of Schinus Terebinthifolius Raddi (Anacardiaceae).

Purpose: To evaluate the peritoneal histopathological changes and culture after the use of intravenous meropenem and intra-abdominal inoculation of 10% aqueous extract of anacardiaceae, in elderly rat model after autogenous fecal peritonitis induced.

Methods: Thirty 18-month-old Wistar rats received induction of autogenous fecal peritonitis and then were stratified into two groups: study I, treated with meropenem (40 mg/kg); and study II, treated with meropenem (40 mg/kg) and intraperitoneal 10% aqueous extract of anacardiaceae. Animals were monitored for 15 days until euthanasia.

Comparative Study of OLP and OLL: Demographic and Clinical Profile in a Reference Center in Brazil.

Objective: To compare the demographic and clinical profiles of oral lichen planus (OLP) and oral lichenoid lesions (OLL) diagnosed at a reference center in Southern Brazil from 2010 to 2019.

Methods: This retrospective study included 117 cases of suspected OLP submitted for biopsy. Investigated variables comprised sociodemographic profiles, medical history, harmful habits, clinical characteristics, and histopathological features.

Clonal shift and impact of azithromycin use on antimicrobial resistance of Staphylococcus aureus isolated from bloodstream infection during the COVID-19 pandemic.

Staphylococcus aureus is a relevant pathogen in bloodstream infections (BSI), and the emergency of the COVID-19 pandemic increased its antimicrobial resistance. S. aureus isolates from BSI (September/2019 - March/2021) were analyzed phenotypically and molecularly, in addition to the clinical features of the patients.
