Metal pollution reconstruction in São Paulo City (Southeast Brazil) over the twentieth century by paleolimnological approach.
Environ Sci Pollut Res Int
January 2025
Ecology Department, Instituto de Botânica, São Paulo, SP, Brazil.
In this study, we evaluated the pollution history by metals over the twentieth century in an urban reservoir (Garças Reservoir, Metropolitan Region of São Paulo, Southeast Brazil) by the paleolimnological approach. The concentrations of eight metals (Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were determined in a Pb-dated sediment core (~ 100 years of information). Metal's enrichment and pollution degree were assessed using the Consensus-Based Sediment Quality Guidelines (CBSQG), enrichment factor (EF), Geoaccumulation Index (I), and Potential Ecological Risk Index (RI).

Objective: To investigate the prognostic value of maternal angiogenic factors in late-onset small fetuses, alone or in combination with the ultrasound and Doppler parameters currently used for the classification of low-risk small-for-gestational-age (SGA) fetuses or high-risk fetal growth restriction (FGR), overall and according to the presence or absence of pre-eclampsia.
Methods: This was a prospective cohort study of women with a singleton pregnancy with a diagnosis of late-onset fetal smallness (defined as birth weight < 10 centile) and a gestational age of ≥ 34 weeks at delivery. Ultrasound assessment of estimated fetal weight (EFW) and Doppler assessment of uterine artery pulsatility index (UtA-PI) and cerebroplacental ratio (CPR) were performed every 1-2 weeks.
Body composition alterations in patients with lung cancer.
Am J Physiol Cell Physiol
January 2025
Department of Medicine, University of Vermont College of Medicine, Burlington, VT, USA.
Most patients with lung cancer experience cancer cachexia (CC), a syndrome of skeletal muscle and adipose tissue wasting. Knowledge of body composition changes in patients is limited, however, because most studies have been cross-sectional, comparing patients with non-cancer controls or patients with and without CC. Few studies, in contrast, have evaluated body composition in patients with lung cancer over time.

Nanomedicine (Lond)
January 2025
Sabanci University Nanotechnology Research and Application Center (SUNUM), Tuzla Istanbul, Turkey.
Aims: This study aims to develop a piezoelectric drug delivery system based on hexagonal boron nitride nanosheets (hBNs).
Materials And Methods: hBNs were synthesized using the chemical vapor deposition (CVD) method and characterized through imaging and spectroscopic techniques. Their piezoelectric properties were evaluated to confirm their functionality.
Molecular diagnosis of infective endocarditis from culture-negative valve samples in a tertiary hospital in Iran.

The aim of this study was to investigate the prevalence of and in valve samples from endocarditis patients using the real-time PCR method at a major referral heart hospital in Iran. In this study, 146 paraffin-embedded tissue samples from the heart valves of patients with clinical and pathological evidence of infective endocarditis (IE), who underwent heart valve replacement surgery between 2016 and 2020 at Tehran Heart Center were collected. After DNA extraction from paraffin-embedded valve tissue samples, they were surveyed for the presence of and using quantitative real-time PCR (qPCR).
