Presence of polyketide synthases and nonribosomal peptide synthetase in culturable bacteria associated with Aplysina fulva and Aplysina caissara (Porifera).

Culture-dependent and -independent studies have provided access to symbiont genes and the functions they play for host sponges. Thus, this work investigates the diversity, presence of genes of pharmacological interest, biological activities and metabolome of the bacteria isolated from the sponges Aplysina caissara and Aplysina fulva collected on the southwestern Atlantic Coast. The genes for Polyketide Synthases types I and II and Nonribosomal Peptide Synthetases were screened in more than 200 bacterial strains obtained, from which around 40% were putatively novel.

The Patterns of P53, E-Cadherin, β-Catenin, CXCR4 and Podoplanin Expression in Oral Squamous Cell Carcinoma Suggests a Hybrid Invasion Model: an Immunohistochemical Study on Tissue Microarrays.

Purpose: Oral squamous cell carcinoma (OSCC) is a significant public health challenge associated with high mortality rates primarily due to its invasive and metastatic behavior. This study aimed to evaluate the expression patterns of five critical biomarkers: β-catenin, E-cadherin, podoplanin (PDPN), CXCR4, and p53 in OSCC tissues and to investigate their correlations with clinicopathologic features and patient outcomes.

Methods: We conducted an immunohistochemical analysis utilizing tissue microarrays (TMAs) from 95 patients diagnosed with primary OSCC.

Putative signaling pathways for contraction and its recovery from DEHP arrest in Hymeniacidon heliophila.

With sessile habits, sponges (phylum Porifera) are susceptible to marine pollution impacts and recently microplastics were identified as one source of contamination. Microplastics have a physical impact on filtration rates and plastics additives such as di(2-ethylhexyl)phthalate (DEHP), a ubiquitous marine contaminant, were already identified in their tissues indicating bioaccumulation. However, few studies assessed the impacts of such compounds in its physiology.

Haplotypic Distribution of SARS-CoV-2 Variants in Cases of Intradomiciliary Infection in the State of Rondônia, Western Amazon.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a high transmissibility profile which favors the accumulation of mutations along its genome, providing the emergence of new variants. In this context, haplotype studies have allowed mapping specific regions and combining approaches and tracking phylogenetic changes. During the COVID-19 pandemic, it was notorious that home environments favored the circulation of SARS-CoV-2, in this study we evaluated 1,407 individuals positive for SARS-CoV-2, in which we located 53 families in the period from June 2021 to February 2023.

Low-dose and ultra-low-dose estradiol and dydrogesterone in postmenopause: an analysis by body mass index.

Objective: Oral, low-dose and ultra-low-dose continuous combined 17β-estradiol (E) plus dydrogesterone (D) reduce vasomotor symptoms (VMS) in postmenopausal women.

Methods: Two phase 3, double-blind studies were included. In the European study, postmenopausal women were randomized 2:1:2 to receive E0.
