Lago Grande do Curuai é um distrito que compreende território vasto e biodiverso no município de Santarém (PA), onde cerca 30 mil pessoas vivem em mais 140 comunidades Projeto Assentamento Agroextrativista (PAE). Em 2022, foi aprovada a realização plebiscito sobre emancipação desse distrito, o ameaça continuidade próprio PAE. O objetivo deste trabalho identificar os aspectos socioambientais imp...

Optical-resolution photoacoustic microscopy (OR-PAM) has become a major experimental tool of photoacoustic tomography, with unique imaging capabilities for various biological applications. However, conventional imaging systems are all table-top embodiments, which preclude their use in internal organs. In this study, by applying the OR-PAM concept to our recently developed endoscopic technique, ...

The phthalate acid esters (PAEs), and, in particular, di(2-ethylhexyl) phthalate (DEHP) and its monoester, monoethylhexyl phthalate (MEHP), can adversely affect rodent testes but only at high doses. Rat gonadal zinc levels can be decreased by the injection of DEHP, but not MEHP. The rat prostate gland seems to be particularly sensitive to PAE-induced zinc depletion. PAE-induced changes in male ...

The bactericidal activities and postantibiotic effects (PAE) of clarithromycin-14-hydroxy-clarithromycin and amoxicillin-clavulanate against Bacteroides fragilis and Peptostreptococcus anaerobius were determined. A concentration of twice the MIC resulted in bactericidal activity against four of four and three of four organisms at 24 h with clarithromycin-14-hydroxy-clarithromycin and amoxicilli...

In this study, balanced and single ended class-E power amplifiers (PAs) were designed and realized for 3.5–3.8GHz band by using Gallium Nitride high electron mobility transistor (GaN HEMT). Realizations were made on low loss Rogers RT5880 dielectric material which has 0.254mm thickness and 2.2 dielectric constant. Proposed balanced class-E PA has approximately 20W (43 dBm) output power with 80%...

Abstract Aim Prostate artery embolisation (PAE) is an approved treatment for men with lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH-LUTS). Evidence of efficacy PAE in patients who are unable void urine spontaneously scant, however. Traditional treatments BPH-LUTS have evidence retention and this series aims report outcomes catheterised patients. Method The records ...

The results of recent laboratory-scale studies regarding the joint effects wet strengthening agent polyamide-amine-epichlorohydrin (PAE) and internal alkylketene dimer (AKD) sizing on Nordic bleached softwood pulp (NBSK) handsheets indicate that AKD increases strength PAE strengthened handsheets. boosting effect was long-lasting. At molecular level actual mechanism behind is unclear. present st...

Maximizing amplifier PAE and associated output power is critical to preserving the detection capabilities of radar systems. The conflicting criterion for maximizing efficiency is amplifier linearity, which is a well studied tradeoff [1,2]. ACPR shows a measure of linearity by directly quantifying the spectral leakage produced at the amplifier output. Load pull techniques are can be used to meas...

BACKGROUND Advances in treatment have increased childhood cancer 5-year survival rates to greater than 80%. However, children previously treated with radiation are at significantly increased risk of developing subsequent neoplasms, the most common of which are skin cancers. The National Cancer Institute and Children's Oncology Group have issued recommendations for survivors treated with radiati...

The relationship between salt bridges and stability/enzymatic activity is unclear. We studied this relationship by systematic alanine-scanning mutation analysis using the typical M4 family metalloprotease Pseudomonas aeruginosa elastase (PAE, also known as pseudolysin) as a model. Structural analysis revealed seven salt bridges in the PAE structure. We constructed ten mutants for six salt bridg...
