Probiotics and Phytobiotics as Dietary and Water Supplements in Biofloc Aquaculture Systems.

Biofloc technology (BFT) is a relatively new microbial-based cultivation system that can be adopted to accomplish more sustainable aquaculture and circularity goals. This review explores aspects of BFT integrating the utilization of probiotics and phytobiotics as dietary and water supplements. This scientific-based snapshot unpacks some physiological pathways and brings a literature review on how these supplements can boost water quality, as well as aquatic species' growth, health, and survival.

Characterisation of cells markers associated with IKZF1 in BCP-ALL.

The presence of IKZF1 deletions has been associated with an increased relapse rate in B-cell precursor acute lymphoblastic leukaemia (BCP-ALL). There is a particular subset of IKZF1 cases called IKZF1 (defined by the co-occurrence of IKZF1 and deletions in CDKN2A/B, PAX5, or the PAR1 region, in the absence of ERG deletions), which is also associated with worse prognosis, but some recent studies have not found major differences between the IKZF1 and IKZF1 groups. Therefore, the IKZF1 group still needs further comprehension and our study aims to characterise the molecular heterogeneity and identify molecular markers exclusively associated with IKZF1.

IKZF1 and BTG1 silencing reduces glucocorticoid response in B-cell precursor acute leukemia cell line.

Introduction: Secondary genetic alterations, which contribute to the dysregulation of cell cycle progression and lymphoid specialization, are frequently observed in B-cell precursor acute lymphoblastic leukemia (B-ALL). As IKZF1 and BTG1 deletions are associated with a worse outcome in B-ALL, this study aimed to address whether they synergistically promote glucocorticoid resistance.

Methods: Small interfering RNA was used to downregulate either IKZF1, or BTG1, or both genes in the 207 B-ALL cell line.

Growth and survival of Betta splendens fed microbial aggregates from ex-situ biofloc technology (BFT).

The betta (Betta splendens) is a carnivorous ornamental species that requires live food. In this study, we evaluated the growth and survival of Betta splendens fingerlings fed ex-situ biofloc (BFT). A total of 375 fingerlings (8.

A biofloc system avoids the adverse effects of diets with suboptimal protein levels on zootechnical performance, intestinal histomorphometry, and protein metabolism of Nile tilapia juvenile fed Spirulina biomass (Arthrospira platensis) as an alternative protein source.

This study aimed to evaluate the effect of the biofloc technology (BFT) system and the replacement of fish meal with Spirulina biomass on productive performance, intestinal histomorphometry, plasma biochemistry, and oxidative stress of Nile tilapia juveniles (Oreochromis niloticus) fed suboptimal levels of protein. Two factors were evaluated: production systems (clear water × BFT) and replacement of fish meal with Spirulina (0, 33, 66 e 100%). The design was in a 2 × 4 randomized factorial scheme with four replications, and the fish were evaluated for 48 days.

Biofloc Technology (BFT) in Aquaculture: What Goes Right, What Goes Wrong? A Scientific-Based Snapshot.

Aquaculture is a crucial industry that can help meet the increasing demand for aquatic protein products and provide employment opportunities in coastal areas and beyond. If incorrectly manage, traditional aquaculture methods can have negative impacts on the environment and natural resources, including water pollution and overuse of wild fish stocks as aquafeed ingredients. Biofloc technology (BFT) may offer a promising solution to some of these challenges by promoting a cleaner and sustainable production system.

A detailed look at the impacts of biofloc on immunological and hematological parameters and improving resistance to diseases.

The innate immunity of invertebrates serves as a critical trait that provides a valuable foundation for studying the common biological responses to environmental changes. With the exponential growth of the human population, the demand for protein has soared, leading to the intensification of aquaculture. Regrettably, this intensification has resulted in the overuse of antibiotics and chemotherapeutics, which have led to the emergence of resistant microbes or superbugs.

The KMT2A recombinome of acute leukemias in 2023.

Chromosomal rearrangements of the human KMT2A/MLL gene are associated with de novo as well as therapy-induced infant, pediatric, and adult acute leukemias. Here, we present the data obtained from 3401 acute leukemia patients that have been analyzed between 2003 and 2022. Genomic breakpoints within the KMT2A gene and the involved translocation partner genes (TPGs) and KMT2A-partial tandem duplications (PTDs) were determined.

The Intracellular and Secreted Sides of Osteopontin and Their Putative Physiopathological Roles.

Classically, osteopontin (OPN) has been described as a secreted glycophosprotein. Indeed, most data concerning its physiological and pathological roles are mainly related to the secreted OPN (sOPN). However, there are several instances in which intracellular OPN (iOPN) has been described, presenting some specific roles in distinct experimental models, such as in the immune system, cancer cells, and neurological disorders.

Outcome of adolescents and young adults with acute lymphoblastic leukemia in a single center in Brazil.

Introduction: Acute lymphoblastic leukemia (ALL) presents a poor prognosis in adults. The adoption of pediatric protocols has been changing this scenario, especially for adolescents and young adults (AYA).

Objective And Method: We aimed to evaluate a consecutive series of patients treated at the State Institute of Hematology of Rio de Janeiro between 2012 and 2020, focusing on the AYA subgroup.

Novel Diagnostic and Therapeutic Options for -Rearranged Acute Leukemias.

The () gene rearrangements (-r) are associated with a diverse spectrum of acute leukemias. Although most -r are restricted to nine partner genes, we have recently revealed that - fusions are often missed during FISH screening of these genetic alterations. Therefore, complementary methods are important for appropriate detection of any -r.

CRLF2 overexpression defines an immature-like subgroup which is rescued through restoration of the PRC2 function in T-cell precursor acute lymphoblastic leukemia.

CRLF2 overexpression has been described as a biomarker of poor prognosis in T-cell acute lymphoblastic leukemia (T-ALL). In the present study, we aimed to unravel the genomic profile underlying CRLF2 overexpression (CRLF2-high) by analyzing RNA-seq, WES, and SNP-array data from 264 T-ALL patients and five cell lines deposited on the TARGET initiative, Cancer Cell Line Encyclopedia and Gene Expression Omnibus. These data allowed us to delineate the genomic landscape of CRLF2-high in T-ALL, which was associated with PTEN, JAK3, PHF6, EZH2, and RUNX1 mutations.

Intensification of Penaeid Shrimp Culture: An Applied Review of Advances in Production Systems, Nutrition and Breeding.

Intensification of the shrimp sector, also referred to as vertical expansion, has been predominately driven by consecutive incidences of global disease outbreaks, which have caused enormous economic loss for the main producer countries. A growing segment of the shrimp farming industry has opted to use production systems with higher density, biosecurity, and operating control to mitigate the risks posed by disease. However, successful super-intensive shrimp production is reliant on an advanced understanding of many important biological and economic parameters in the farming system, coupled with effective monitoring, to maintain optimal production.

IKZF1 deletions associate with CRLF2 overexpression leading to a poor prognosis in B-cell precursor acute lymphoblastic leukaemia.

Cytokine Receptor-Like Factor 2 (CRLF2) overexpression occurs in 5-15% of B-cell precursor acute lymphoblastic leukaemia (B-ALL). In ∼50% of these cases, the mechanisms underlying this dysregulation are unknown. IKAROS Family Zinc Finger 1 (IKZF1) is a possible candidate to play a role in this dysregulation since it binds to the CRLF2 promoter region and suppresses its expression.

Implementation of a pharmacogenomic program in a Brazilian public institution.

This narrative review describes implementation, current status and perspectives of a pharmacogenomic (PGx) program at the Brazilian National Cancer Institute (INCA), targeting the cancer chemotherapeutic drugs - fluoropyrimidines, irinotecan and thiopurines. This initiative, designed as a research project, was supported by a grant from the Brazilian Ministry of Health. A dedicated task force developed standard operational procedures from recruitment of patients to creating PGx reports with dosing recommendations, which were successfully applied to test 100 gastrointestinal cancer INCA outpatients and 162 acute lymphoblastic leukemia pediatric patients from INCA and seven other hospitals.
