A Radiologia no Tratamento Oncológico: O Estado da Arte

Enquadramento: O avanço da radiologia tem sido crucial no tratamento oncológico, evoluindo de sistemas rudimentares, como o Integris V5000 em 1997, para tecnologias híbridas atuais, como o Alphenix 4D CT, que combinam angiografia e tomografia computadorizada (TC). Essas inovações permitem maior precisão diagnóstica e terapêutica, reduzindo riscos associados a radiação e contraste iodado [1-3]. Objetivo: Descrev...

Genomic Analysis of Antibiotic Resistance and Virulence Profiles in Escherichia...

Sternal bursitis is an underexplored lesion in poultry, often overlooked in microbiological diagnostics. In this study, we characterized 36 Escherichia coli isolates recovered from sternal bursitis in broiler chickens, combining phenotypic antimicrobial susceptibility testing, PCR-based screening, and whole genome sequencing (WGS). The genetic analysis revealed a diverse population spanning 15 sequence types, i...

Improving genetic diagnostics for patients with negative exome sequencing using...

Next-generation sequencing (NGS) can be performed using several different platforms. Detecting DNA alterations that affect human health is now possible because of NGS technologies [1]. Despite the advancements in NGS, challenges persist, particularly in cases where traditional exome sequencing yields negative results. Sequencing of the entire genome provides global information about exons and introns, which can...

Genetic Complexity of CC5 Isolates Associated with Sternal Bursitis in Chickens...

Sternal bursitis, a common inflammatory condition in poultry, poses significant challenges to both animal welfare and public health. This study aimed to investigate the prevalence, antimicrobial resistance, and genetic characteristics of isolates associated with sternal bursitis in chickens. Ninety-eight samples were collected from affected chickens, and 24 isolates were identified. Antimicrobial susceptibility...

The status and management of web-related security at higher education instituti...

In an era marked by escalating cyber threats, the need for robust cybersecurity measures is paramount, especially for Higher Education Institutions (HEIs). As custodians of sensitive information, HEIs must ensure secure channels for data transmission to protect their stakeholders. These institutions should increase their cyber resilience, recognizing the heightened risk they face from cybercriminal activities. ...

Bank Market Power, Firm Performance, Financing Costs and Capital Structure

In this study, we provide a thorough analysis, conducted on a company-by-company basis, of the impact of bank concentration and the bank-relative power of banks on firm profitability, financing costs, and capital structure in a small economy like Portugal. Using a sample of 434,990 Portuguese companies, the study spans a time frame of 13 years (from 2006 to 2018). Principal component analysis (PCA) was used to ...

Unlocking portfolio resilient and persistent risk: A holistic approach to unvei...

Purpose: This study identifies residual, persistent, or resilient risks that remain even after controls for systematic and sentiment risk and extensive portfolio diversification are applied. Method: This methodology employs the Newey-West regression analysis in conjunction with the Lagrange multiplier method to construct a global minimum variance portfolio. This analysis focuses explicitly on the diversifiable ...
