Seleção de matrizes e clones de mangabeira para o cultivo in vitro Selection of parents and clones of mangabeira for in vitro cultivation

Pesquisa Agropecuária Brasileira, 2004
Altas taxas de mortalidade em viveiro de mudas de mangabeira (Hancornia speciosa) impedem seu uso na reversão do processo de degradação das terras e na manutenção da produtividade e integridade ambiental do Cerrado.

Lung Cancer Patients Display Increased Expression of Bovine Meat and Milk Factor (BMMF) Proteins in Peritumor Alveolar Macrophages

International Journal of Cancer, EarlyView.
Plasmid‐like DNA sequences frequently found in bovine milk and serum have been proposed as infectious agents promoting indirect carcinogenesis. This multi‐omics study detected immune cells positive for these bovine meat and milk factors (BMMFs) in patients with lung cancer, with BMMF expression inversely correlated with smoking intensity.

Dynamic miRNA landscapes unlock sexual plasticity in protogynous orange-spotted grouper under MT-implantation

Aquaculture Reports
Sex change, a manifestation of sexual plasticity, is widespread among fish, yet its molecular regulatory mechanisms, particularly those involving miRNAs, remain largely unresolved.

Epigenetic Markers of Cell Division and Ageing in Relation to Breast Cancer Survival

International Journal of Cancer, EarlyView.
ABSTRACT Breast cancer remains a major challenge to public health. Biomarkers may be useful to improve prediction of breast cancer survival. Several epigenetic markers of cell division and ageing based on DNA methylation have been proposed. In this study, we measured these epigenetic markers in breast tumours and assessed their prognostic value.

Masculinización de tilapia roja (Oreochromis spp) por inmersión utilizando 17 alfa–metiltestosterona Red tilapia (Oreochromis spp) masculinization by immersion using 17 alpha-methyltestosterone

Revista Colombiana de Ciencias Pecuarias, 2007
La tilapia roja (Oreochromis spp) es ampliamente producida a nivel mundial. Un inconveniente para su producción es la alta precocidad para la reproducción, lo que afecta su crecimiento y ocasiona la superpoblación.

C. elegans germ cells switch between distinct modes of double-strand break repair during meiotic prophase progression.

PLoS Genetics, 2007
Chromosome inheritance during sexual reproduction relies on deliberate induction of double-strand DNA breaks (DSBs) and repair of a subset of these breaks as interhomolog crossovers (COs).

Macrophage extracellular vesicles deliver Mef2d proteins to aggravate Bacteroides fragilis pathogenicity in type 2 diabetes arterial calcification

Interdisciplinary Medicine, EarlyView.
Bacteroides fragilis is associated with type 2 diabetes (T2D) arterial calcification and can be activated by macrophage‐derived extracellular vesicles (EVs). BF takes up EVs via receptor‐mediated endocytosis, and activation is induced by EV‐derived Mef2d, thereby inhibiting ArsR family transcriptional regulator transcription.

Impact of cystic fibrosis transmembrane conductance regulator modulator therapies on liver stiffness and liver enzymes: An observational perspective single‐center cohort study

JPGN Reports, EarlyView.
Abstract Objectives The efficacy of cystic fibrosis transmembrane conductance regulator (CFTR)‐modulator therapies in preventing or ameliorating cystic fibrosis liver disease (CFLD) by correcting CFTR in cholangiocytes is not well‐documented. This study aimed to assess liver function during CFTR‐modulators.

Normal sexual dimorphism in theory of mind circuitry is reversed in Schizophrenia

Social Neuroscience, 2018
The ability to mentalize, or theory of mind (ToM), is sexually dimorphic in humans and impaired in schizophrenia. This sex-stratified study probed cognitive (indexed by intelligence) and affective (indexed by olfactory tasks) contributions to ToM performance in 37 individuals with schizophrenia and 31 healthy controls.
