Genomic and phenotypic stability of fusion-driven pediatric sarcoma cell lines.

Human cancer cell lines are the mainstay of cancer research. Recent reports showed that highly mutated adult carcinoma cell lines (mainly HeLa and MCF-7) present striking diversity across laboratories and that long-term continuous culturing results in genomic/transcriptomic heterogeneity with strong phenotypical implications. Here, we hypothesize that oligomutated pediatric sarcoma cell lines mainly driven by a fusion transcription factor, such as Ewing sarcoma (EwS), are genetically and phenotypically more stable than the previously investigated adult carcinoma cell lines.

Clinical outcomes and anti-inflammatory mechanisms predict maximum heart rate improvement after physical activity training in individuals with psychiatric disorders and comorbid obesity.

Introduction: This study aimed to evaluate the predictive validity and discriminatory ability of clinical outcomes, inflammatory activity, oxidative and vascular damage, and metabolic mechanisms for detecting significant improve maximum heart rate after physical activity training in individuals with psychiatric disorders and obesity comorbid using a longitudinal design and transdiagnostic perspective.

Methods: Patients with major depressive disorder, bipolar disorder and, schizophrenia and with comorbid obesity (n = 29) were assigned to a 12-week structured physical exercise program. Peripheral blood biomarkers of inflammation, oxidative stress, vascular mechanisms, and metabolic activity, as well as neurocognitive and functional performance were assessed twice, before and after intervention.

Macroevolutionary inference of complex modes of chromosomal speciation in a cosmopolitan plant lineage.

The effects of single chromosome number change-dysploidy - mediating diversification remain poorly understood. Dysploidy modifies recombination rates, linkage, or reproductive isolation, especially for one-fifth of all eukaryote lineages with holocentric chromosomes. Dysploidy effects on diversification have not been estimated because modeling chromosome numbers linked to diversification with heterogeneity along phylogenies is quantitatively challenging.

Framing challenges and polarized issues in invasion science: toward an interdisciplinary agenda.

In a hyperconnected world, framing and managing biological invasions poses complex and contentious challenges, affecting socioeconomic and environmental sectors. This complexity distinguishes the field and fuels polarized debates. In the present article, we synthesize four contentious issues in invasion science that are rarely addressed together: vocabulary usage, the potential benefits of nonnative species, perceptions shifting because of global change, and rewilding practices and biological invasions.

LRH-1/NR5A2 targets mitochondrial dynamics to reprogram type 1 diabetes macrophages and dendritic cells into an immune tolerance phenotype.

Background: The complex aetiology of type 1 diabetes (T1D), characterised by a detrimental cross-talk between the immune system and insulin-producing beta cells, has hindered the development of effective disease-modifying therapies. The discovery that the pharmacological activation of LRH-1/NR5A2 can reverse hyperglycaemia in mouse models of T1D by attenuating the autoimmune attack coupled to beta cell survival/regeneration prompted us to investigate whether immune tolerisation could be translated to individuals with T1D by LRH-1/NR5A2 activation and improve islet survival.

Methods: Peripheral blood mononuclear cells (PBMCs) were isolated from individuals with and without T1D and derived into various immune cells, including macrophages and dendritic cells.

Active and passive organic carbon fluxes during a bloom in the Southern Ocean (South Georgia).

The Controls Over Mesopelagic Interior Carbon Storage (COMICS) cruise DY086 took place aboard the RRS Discovery in the South Atlantic during November and December, 2017. Physical, chemical, biogeochemical and biological data were collected during three visits to ocean observatory station P3, off the coast of South Georgia, during an austral spring bloom. A diverse range of equipment including CTD-rosette, Acoustic Doppler Current Profiler (ADCP), net deployments, marine snow catchers (MSCs), Stand Alone Pump System (SAPS) and PELAGRA Sediment Traps were used to produce a comprehensive, high-quality dataset.

Assessing the effects of electromagnetic fields generated by submarine power cables on the soft-bottom community: An ecological in-situ study.

This study represents the first in situ investigation into the effects of magnetic fields (MFs) on soft-bottom macrofauna communities, laying the groundwork for further studies to better understand their potential consequences on marine ecosystems. Conducted in the Natural Park of the Strait (Southern Iberian Peninsula), the study measured MFs generated by HVAC cables and assessed their impact on soft-bottom macrofauna communities by comparing areas exposed to MFs with two control areas at different depths. Measured MF intensities were relatively low, with a maximum deviation from background levels of 34 nT near the cable, decreasing to 1 nT at 250 m distance.

Laparoscopic right hemicolectomy with complete mesocolon excision and cranial approach.

Background: Complete mesocolon excision (CME) and D3-lymphadenectomy concepts have gained popularity for the surgical treatment of right colon cancer in comparison to the conventional laparoscopic right hemicolectomy (CLRH). The rationale of CME is to dissect the embryological planes between the mesenteric plane and the parietal fascia to remove the mesentery within a complete envelope of mesenteric fascia and visceral peritoneum that contains lymph nodes, the central vascular ligation, and adequate bowel length to remove involved pericolic lymph nodes in the longitudinal direction, having as the main goal to improve the oncological results. CME with D3-lymphadenectomy is challenge since involves the excision of the lymph adipose tissue covering the medial edge of the superior mesenteric vein (SMV) (trunk of Gillot, TG), and the gastrocolic trunk of Henle (GTH).

Multi-strain probiotic formula modulates expression of β-defensin-2, β-defensin-3, and TLR-4 in male rats with apical periodontitis.

Objective: Evaluate whether a multi-strain probiotic formula affects blood parameters (hematologic, calcium, and phosphorus levels) and alters the expression of β-defensin-2, β-defensin-3, and toll-like receptor 4 in male rats with induced apical periodontitis (AP).

Design: Wistar rats were divided into two groups (n = 8 each): (1) rats with AP on a regular diet (Control) and (2) rats with AP on a regular diet supplemented with the multi-strain probiotic GNC Probiotic Complex (GCP) at one billion CFU. AP was induced by exposing the dental pulp of the first molars to the oral environment.

In silico and in vitro evaluation of potential agonistic and antagonistic estrogenic and androgenic activities of pure cyanotoxins, microcystin-LR and cylindrospermopsin.

The potential endocrine disruption activity of cyanotoxins, particularly their effects on estrogen and androgen receptors (ER, AR), remains poorly understood. In the present study, the potential agonistic/antagonistic estrogenic and androgenic activities of MC-LR and CYN have been determined for the first time with validated OECD Test Guidelines No. 455 and 458, respectively.

Integrating genomic evidence for an updated taxonomy of the bacterial genus Spiribacter.

The genus Spiribacter encompasses halophilic bacteria widely distributed in hypersaline environments worldwide. Despite their ecological significance, initially isolating Spiribacter species under laboratory settings was challenging due to the lack of knowledge of their growth and cultivation requirements. However, with improved understanding of their ecological niche and metabolic pathways, additional species of Spiribacter have been successfully isolated and identified from diverse locations around the globe.

Brain reserve in hepatic encephalopathy: Pathways of damage and preventive strategies through lifestyle and therapeutic interventions.

Brain reserve is an important concept to understand the variability of damage associated with brain-related diseases and includes the adaptation of cognitive processes to preserve brain function. A good cognitive reserve might delay the onset of clinical manifestations of neurodegenerative diseases as well as hepatic encephalopathy, improving the quality of life in patients with chronic liver diseases. By stimulating activities and maintaining overall health, individuals may be able to enhance their brain's resilience to age-related changes and pathology.
