Mental health impact of the COVID-19 pandemic on patients with neurodegenerative diseases and perceived family caregiver burden in Lima, Peru.

Background: Neurodegenerative diseases lead to difficulties with functional activities. In Peru, most caregivers are family members. Little is known about the COVID-19 pandemic's effect on caregivers in Peru.

Heavy metal resistance genes and plasmid-mediated quinolone resistance genes in Arthrobacter sp. isolated from Brazilian soils.

Arthrobacter sp. are Gram-positive bacilli commonly obtained from soil and in the hospital environment. These species have been reported to cause several types of infection.

Characterization of Acquired Antimicrobial Resistance Genes in Environmental Isolates from Brazil.

is an opportunist pathogen that has intrinsic resistance to the majority of antibiotics and has a high ability to adapt in different environments; however, there are few reports of acquired resistance genes in . The aim of this study was to investigate the antimicrobial resistance profile, the presence of mutations in the quinolone-resistance determining region the presence of acquired resistance genes, and the different plasmid families in isolated from Brazilian soils. A total of 16 isolates were obtained from a variety of agricultural soils with different cultures of Brazil and they were nonsusceptible to most of the antibiotics tested.

Replicon typing of plasmids in environmental Achromobacter sp. producing quinolone-resistant determinants.

This study aimed to investigate the antimicrobial resistance profile to quinolones, the presence of quinolone-resistant determinants and the plasmid replicon typing in environmental Achromobacter sp. isolated from Brazil. Soil and water samples were used for bacterial isolation.

Detection of different β-lactamases encoding genes, including bla, and plasmid-mediated quinolone resistance genes in different water sources from Brazil.

Bacterial resistance occurs by spontaneous mutations or horizontal gene transfer mediated by mobile genetic elements, which represents a great concern. Resistance to β-lactam antibiotics is mainly due to the production of β-lactamases, and an important mechanism of fluoroquinolone resistance is the acquisition plasmid determinants. The aim of this study was to verify the presence of β-lactamase-encoding genes and plasmid-mediated quinolone resistance genes in different water samples obtained from São Paulo state, Brazil.

The Drosophila melanogaster Eip74EF-PA transcription factor directly binds the sciarid BhC4-1 promoter.

The DNA puff BhC4-1 gene of Bradysia hygida (Diptera, Sciaridae) is amplified and expressed in the salivary glands at the end of the last larval instar. Even though there are no BhC4-1 orthologs in Drosophila melanogaster, the mechanisms that regulate BhC4-1 gene expression in B. hygida are for the most part conserved in D.

Presence of β-Lactamase Encoding Genes in Burkholderia cepacia Complex Isolated from Soil.

Burkholderia cepacia complex has emerged as an important opportunistic bacteria group for immunocompromised patients, and it has a high level of intrinsic resistance for different antibiotic classes. Hydrolysis of β-lactam antibiotics by β-lactamases is the most common resistance mechanism in Gram-negative bacteria, and the presence of such enzymes complicates the selection of appropriate therapy. This study aimed at investigating the antimicrobial resistance profile and the presence of β-lactamase encoding genes in B.

Low prevalence of human papillomavirus in head and neck squamous cell carcinoma in the northwest region of the Philippines.

Background: Geographic heterogeneity of human papillomavirus (HPV) involvement in head and neck squamous cell carcinoma (HNSCC) has been observed over the last few years. This trend has not been evaluated in the Philippines. Hence, this study aims to provide for the first time a data on the prevalence of HPV in HNSCC in the northwestern region of the Philippines.
