The impact of neonicotinoid insecticides on amphibians: A comprehensive review and future research challenges.

Neonicotinoid insecticides (NNIs) are widely used in agriculture; however, their effects on anuran amphibians remain poorly explored. This global review critically examines the existing literature, with data obtained from Web of Science and Scopus databases. A total thirty-seven studies were published from 2004 to 2023.

Nonbacterial thrombotic endocarditis of mitral valve associated with a lymphoproliferative malignancy: case report and literature review.

Background: Non-bacterial thrombotic endocarditis (NBTE) is a rare condition marked by sterile vegetations on cardiac valves, often linked to rheumatologic diseases, autoimmune disorders, and advanced solid malignancies. An early diagnosis and treatment of the associated clinical condition are mandatory, although they do not usually eliminate valvular vegetations, making anticoagulation essential to prevent embolic events. Despite variability, the prognosis of NBTE is usually unfavorable due to recurrent embolic events and the severity of the primary condition, typically advanced cancer.

Systemic disease presenting as cardiac tamponade: a case report.

Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by multisystem inflammation and is a common cause of pericarditis and pericardial effusion, but significant pericardial effusion and cardiac tamponade are rare and even rarer as the first manifestation.

Case Summary: We report the case of a young male who presented with fever, recurrent pericarditis, and polyserositis with pericardial and bilateral pleural effusion. On examination, he was haemodynamically unstable and the pericardial effusion had considerable dimensions and an urgent pericardiocentesis was performed.

Heart surgery waiting list management in an ultra-peripheral region: impact of a risk-stratified queuing method.

Background: The management of heart surgery waiting list is essential, particularly in ultraperipheral regions. We aimed to characterise a cohort of patients awaiting surgery in such a region, and to assess the occurrence of adverse events and causative factors.

Methods: A retrospective, multicentre analysis from 2016 to 2020.

Safety and Immunogenicity of an Muscle Electroporation Delivery System for DNA- Tuberculosis Vaccine in Cynomolgus Monkeys.

A Bacille Calmette-Guérin (BCG) is still the only licensed vaccine for the prevention of tuberculosis, providing limited protection against Mycobacterium tuberculosis infection in adulthood. New advances in the delivery of DNA vaccines by electroporation have been made in the past decade. We evaluated the safety and immunogenicity of the DNA-hsp65 vaccine administered by intramuscular electroporation (EP) in cynomolgus macaques.

Primary cardiac lymphoma: The unusual suspect and the importance of a multimodality approach.

Unlabelled: Primary cardiac lymphomas are rare tumors with heterogeneous presentation, often difficult to diagnose, requiring a high level of clinical suspicion. An attempted diagnosis is fundamental for effective treatment. We report a very rare case of a primary cardiac lymphoma in a middle-age female patient that presented with atrial flutter, atrioventricular conduction disorder, and a secondary autoimmune hemolytic anemia with cold agglutinin syndrome.

Fatty acids homeostasis during fasting predicts protection from chemotherapy toxicity.

Fasting exerts beneficial effects in mice and humans, including protection from chemotherapy toxicity. To explore the involved mechanisms, we collect blood from humans and mice before and after 36 or 24 hours of fasting, respectively, and measure lipid composition of erythrocyte membranes, circulating micro RNAs (miRNAs), and RNA expression at peripheral blood mononuclear cells (PBMCs). Fasting coordinately affects the proportion of polyunsaturated versus saturated and monounsaturated fatty acids at the erythrocyte membrane; and reduces the expression of insulin signaling-related genes in PBMCs.

Double coronary anomaly: A case report.

Unlabelled: We describe an extremely rare case of a 37-year-old female patient who presented with exertional angina and was diagnosed with a unique coronary anomaly with an anomalous right coronary artery with origin in the left anterior descending artery and a fistula between this anomalous coronary artery and the pulmonary artery.

Learning Objectives: Most patients with coronary anomalies are asymptomatic but some may have angina caused by a coronary steal phenomenon, myocardial infarction, or even sudden death depending on the circuit and characteristics of the anomaly.The combination of multiple coronary anomalies is extremely rare.

Production of Fucoxanthin from Using High Performance Countercurrent Chromatography Retaining Its FOXO3 Nuclear Translocation-Inducing Effect.

is a rich source of fucoxanthin, a carotenoid with several health benefits. In the present study, high performance countercurrent chromatography (HPCCC) was used to isolate fucoxanthin from an extract of . A multiple sequential injection HPCCC method was developed combining two elution modes (reverse phase and extrusion).

Conservation of Aging and Cancer Epigenetic Signatures across Human and Mouse.

Aging and cancer are two interrelated processes, with aging being a major risk factor for the development of cancer. Parallel epigenetic alterations have been described for both, although differences, especially within the DNA hypomethylation scenario, have also been recently reported. Although many of these observations arise from the use of mouse models, there is a lack of systematic comparisons of human and mouse epigenetic patterns in the context of disease.

Transient metabolic improvement in obese mice treated with navitoclax or dasatinib/quercetin.

Senescent cells accumulate with obesity in the white adipose tissue of mice and humans. These senescent cells enhance the pro-inflammatory environment that, with time, contributes to the onset of glucose intolerance and type 2 diabetes. Glucose intolerance in mouse models of obesity has been successfully reversed by the elimination of senescent cells with the senolytic compounds navitoclax or the combination of dasatinib and quercetin (D/Q).

Identification and characterization of Cardiac Glycosides as senolytic compounds.

Compounds with specific cytotoxic activity in senescent cells, or senolytics, support the causal involvement of senescence in aging and offer therapeutic interventions. Here we report the identification of Cardiac Glycosides (CGs) as a family of compounds with senolytic activity. CGs, by targeting the Na+/K+ATPase pump, cause a disbalanced electrochemical gradient within the cell causing depolarization and acidification.

The Need to Consider Context in the Evaluation of Anti-infectious and Immunomodulatory Effects of Vitamin A and its Derivatives.

Vitamin A and its derivatives (retinoids) act as potent regulators in many aspects of mammalian reproduction, development, repair, and maintenance of differentiated tissue functioning. Unlike other vitamins, Vitamin A and retinoids, which have hormonal actions, present significant toxicity, which plays roles in clinically relevant situations, such as hypervitaminosis A and retinoic acid ("differentiation") syndrome. Although clinical presentation is conspicuous in states of insufficient or excessive Vitamin A and retinoid concentration, equally relevant effects on host resistance to specific infectious agents, and in the general maintenance of immune homeostasis, may go unnoticed, because their expression requires either pathogen exposure or the presence of inflammatory co-morbidities.

High-Throughput Image-Based Screening to Identify Chemical Compounds Capable of Activating FOXO.

FOXO proteins are transcription factors with important roles in the regulation of the expression of genes involved in cell growth, proliferation, differentiation, and longevity. FOXO proteins are active in the nucleus but, upon post-translational modification they form a docking site for 14-3-3 proteins and are translocated to the cytoplasm where they are inactive.We make use of this regulatory mechanism of FOXO proteins to develop an image-based high-throughput screening platform to detect compounds that regulate FOXO3 subcellular localization.

Sirt1 protects from K-Ras-driven lung carcinogenesis.

The NAD-dependent deacetylase SIRT1 can be oncogenic or tumor suppressive depending on the tissue. Little is known about the role of SIRT1 in non-small cell lung carcinoma (NSCLC), one of the deadliest cancers, that is frequently associated with mutated K-RAS Therefore, we investigated the effect of SIRT1 on K-RAS-driven lung carcinogenesis. We report that SIRT1 protein levels are downregulated by oncogenic K-RAS in a MEK and PI3K-dependent manner in mouse embryo fibroblasts (MEFs), and in human lung adenocarcinoma cell lines.

Novel lineage- and stage-selective effects of retinoic acid on mouse granulopoiesis: Blockade by dexamethasone or inducible NO synthase inactivation.

Despite the close relationship of eosinophils and neutrophils, these granulocyte lineages respond to distinct cytokines and play unique roles in immune responses. They nevertheless respond to shared physiological/pharmacological regulators, including glucocorticoids and retinoids, and to ubiquitous mediators, including NO. Others showed that, in humans, all-trans retinoic acid (ATRA) suppresses eosinophil differentiation, but promotes neutrophil differentiation.

Essential roles of PKA, iNOS, CD95/CD95L, and terminal caspases in suppression of eosinopoiesis by PGE2 and other cAMP-elevating agents.

Up- and downregulation of eosinopoiesis control pulmonary eosinophilia in human asthma. In mice, eosinopoiesis is suppressed in vitro by prostaglandin E2 (PGE2) and in vivo by diethylcarbamazine, through a proapoptotic mechanism sequentially requiring inducible NO synthase (iNOS) and the ligand for death receptor CD95 (CD95L). We examined the roles of iNOS, cAMP-mediated signaling, caspases, and CD95L/CD95 in suppression of eosinopoiesis by PGE2 and other agents signaling through cAMP.

Factors related with adiponectinemia in obese and normal-weight women and with its variation in weight loss programs.

Objective: To assess different factors influencing adiponectinemia in obese and normal-weight women; to identify factors associated with the variation (Δ) in adiponectinemia in obese women following a 6-month weight loss program, according to surgical/non-surgical interventions.

Methods: We studied 100 normal-weight women and 112 obese premenopausal women; none of them was on any medical treatment. Women were characterized for anthropometrics, daily macronutrient intake, smoking status, contraceptives use, adiponectin as well as IL-6 and TNF-α serum concentrations.
