Assessment of heavy metals, PAHs, and pesticide levels in yerba mate on the European market.

Although yerba mate has been known and used for hundreds of years, not all of its properties have been fully understood yet. Yerba mate is a source of many desirable substances, but it may also contain toxic metals and other substances that are harmful to health. Fifteen samples of yerba mate tea from three South American countries were analyzed.

Ultrasound biometry for estimating delivery dates in small and medium breed cats.

This research investigated the development of fetal and feto-maternal structures and their correlation to the time leading up to parturition during pregnancy in small and medium breeds of domestic cats. The experiment involved 53 purebred queens assigned to two groups based on their weight. Ultrasound examinations were performed weekly from the 15th day after the last mating until delivery.

Incidence and Dynamics of CRC Stage Migration: A Regional vs. a National Analysis.

Background/objectives: Due to an increased rate of surveillance colonoscopy, we aim to determine the impact of stage migration on the incidence and overall survival (OS) of patients who underwent pathological staging of colorectal cancer (CRC) at our Health Network System.

Methods: Two datasets were included: subjects from the tumor registry at a regional Comprehensive Cancer Center = 1385) and subjects from the Surveillance, Epidemiology, and End Results (SEER) national database ( = 202,391).

Results: A significant increase in the diagnosis of CRC Stage 1 and 4 was observed, with a decrease in stage 2, and no change in Stage 3 in the National datasets ( < 0.

Signals, tracks, and trams: public transport signal priority impact on job accessibility over time.

Improving travel time by public transport is a major task for city planners and policy makers to increase its competitiveness relative to cars which can be facilitated by implementing public transport preferential infrastructure treatments such as signal priority. We study the impact of one such preferential treatment, signal priority, on accessibility to jobs between 2015 and 2022 in Warsaw, Poland, which implemented signal priority on 187 intersections during this time period. We develop a method to extract inter-stop travel times from the General Transit Feed Service.

COVID-19 vaccination hesitance and adverse effects among US adults: a longitudinal cohort study.

Introduction: Although Coronavirus disease 2019 (COVID-19) vaccination is critical to control its spread, vaccine hesitancy varies significantly among the United States population; moreover, some vaccine recipients experienced various adverse effects. We aim to assess the impact of COVID-19 vaccine hesitancy in a university-affiliated community, the factors affecting participants' decisions, and their adverse effects.

Methods: A pre-vaccination online Institutional Review Board IRB-approved survey was emailed in Nov/Dec 2020, 2 months before the implementation of state-policy protocols for COVID-19 vaccination.
