This study presents a novel miniaturized device as a 3D-printed microfluidic magnetic platform specifically designed to manipulate magnetic microparticles in a microfluidic chip for rapid deoxyribonucleic acid (DNA) isolation. The novel design enables the movement of the magnetic particles in the same or opposite directions with the flow or suspends them in continuous flow. A computational model was developed to assess the effectiveness of the magnetic manipulation of the particles. Superparamagnetic monodisperse silica particles synthesized in-house are utilized for the isolation of fish sperm DNA and human placenta DNA. It was demonstrated that the proposed platform can perform DNA isolation within 10 min with an isolation efficiency of 50% at optimum operating conditions.

Salmonella presents a significant threat to the health of animals and humans, especially with the rise of strains resistant to multiple drugs. This highlights the necessity for creating sustainable and efficient practical approaches to managing salmonellosis. The most recent and safest approach to combat antimicrobial resistance-associated infections is lytic bacteriophages.

Purpose: Hematological toxicities (HTs) in lung cancer (LCa) may compromise the delivery of Radio-Chemotherapy (RTCT), and consequently affect the control of the disease. The aim of this study is to evaluate the association of Single nucleotide polymorphisms (SNPs) with HT.
Material/methods: In this prospective multicentre study, 264 patients with primary LCa treated with RTCT between 2012 and 2018 were included.

The construction of artificial reefs (ARs) is an effective way to restore habitats and increase and breed fishery resources in marine ranches. However, studies on the impacts of ARs on the structure, function, and assembly patterns of the bacterial community (BC), which is important in biogeochemical cycles, are lacking. The compositions, diversities, assembly patterns, predicted functions, and key environmental factors of the attached and free-living microbial communities in five-year ARs (O-ARs) and one-year ARs (N-ARs) in Fangchenggang, China, were analyzed via 16S rRNA gene sequencing.

Hepatitis B virus (HBV) is a major public health concern responsible for hepatitis and hepatocellular carcinoma (HCC) worldwide. In Mozambique, HBsAg prevalence is high and endemic, and despite the strategies to mitigate the spread of the disease, the HCC incidence is still high and one of the highest in the world. There is still limited data on the serological profile and molecular epidemiology of HBV in Mozambique given the burden of this disease.
