Association of Neuroblastoma (NB) SH-SY5Y Cells with Antibodies of Parasitic Origin (Anti- and Anti-).

It is little known that trophozoites and eggs can reduce tumors in vitro and animal models. Although this has been known for many years, the mechanism that induces the antitumor effect in these parasites is still not known. We employed Western blot (WB) and immunofluorescence (IFC) by confocal microscopy to explore the potential protein binding between neuroblastoma (NB) SH-SY5Y cells and anti- and anti- antibodies.

Prognostic Nutritional Index is a valuable preoperative prognostic biomarker in Mexican patients surgically intervened on gastrointestinal stromal tumors: a retrospective cohort study.

Purpose: The immunonutritional status of cancer patients has a profound impact on lifespan. Prognostic Nutritional Index (PNI) evaluates prognosis in operated patients with both neoplastic and non-neoplastic conditions. This study estimates the overall survival (OS) of Mexican patients operated on gastrointestinal stromal tumors (GIST) based on PNI.

Identification of potential new T cell activation molecules: a Bioinformatic Approach.

T-cell activation is central for the initiation of T cell mediated adaptive immune response and is the result of the close communication between the Antigen Presenting Cell (APC) and the T lymphocyte. Although T-cell activation is currently well understood, and many intracellular pathways are well characterized, nevertheless new players are constantly identified, and this complements the known protein interactome. In this work we aimed to identify new proteins involved in T cell activation.

Tumor-Suppressive Cross-Linking of Anti- Antibodies in Acute Lymphoblastic Leukemia.

Parasites have been associated with possible anticancer activity, including , which has been linked to inhibiting the growth of solid tumors. To better understand this antitumor effect, we investigated the association of anti- antibodies with B cells of the acute lymphoblastic leukemia (ALL) SUPB15 cell line. The antibodies were generated in rabbits.

The Helicobacter pylori infection alters the intercellular junctions on the pancreas of gerbils (Meriones unguiculatus).

Helicobacter pylori is a common resident in the stomach of at least half of the world's population and recent evidence suggest its emergence in other organs such as the pancreas. In this organ, the presence of H. pylori DNA has been reported in cats, although the functional implications remain unknown.

Mediation effect of body mass index on the association between serum magnesium level and insulin resistance in children from Mexico City.

Background/objectives: Reduced serum magnesium (Mg) levels have been associated with obesity, insulin resistance (IR), type 2 diabetes, and metabolic syndrome in adults. However, in the children population, the evidence is still limited. In this cross-sectional study, we aimed to analyze the association of serum Mg levels with the frequency of overweight and obesity and cardiometabolic traits in 189 schoolchildren (91 girls and 98 boys) between 6 and 12 years old from Mexico City.

Plant-Origin Components: New Players to Combat Antibiotic Resistance in .

(Kpn) is an opportunistic pathogen that causes intrahospital complications such as pneumonia, liver abscesses, soft tissue infections, urinary infections, bacteraemia, and, in some cases, death. Since this bacterium has a higher frequency than other Gram-negative pathogens, it has become an important pathogen to the health sector. The adaptative genome of Kpn likely facilitates increased survival of the pathogen in diverse situations.

Metabolic effects of milk fatty acids: A literature review.

Milk and dairy products are known to have a significant role in human development and tissue maintenance due to their high nutritional value. With the higher incidence of obesity and metabolic diseases, nutrition and public health authorities have recommended the intake of fat-free or low-fat dairy due to the saturated fatty acid content of whole-fat products and their effect on serum cholesterol levels. However, recent studies have questioned the association between milk fat consumption and cardiometabolic risk.

A Modified Sonographic Algorithm for Image Acquisition in Life-Threatening Emergencies in the Critically Ill Newborn.

The use of routine point-of-care ultrasound (POCUS) is increasing in neonatal intensive care units (NICUs), with several centers advocating for 24 h equipment availability. In 2018, the sonographic algorithm for life-threatening emergencies (SAFE) protocol was published, which allows the assessment of neonates with sudden decompensation to identify abnormal contractility, tamponade, pneumothorax, and pleural effusion. In the study unit (with a consulting neonatal hemodynamics and POCUS service), the algorithm was adapted by including consolidated core steps to support at-risk newborns, aiding clinicians in managing cardiac arrest, and adding views to verify correct intubation.

Malignant peripheral nerve sheath tumor on a patient with a maternally inherited novel NF1 gene pathogenic germline variant: Case report.

Introduction: Neurofibromatosis type 1 (NF1) is an autosomal dominant cancer predisposition syndrome caused by pathogenic variants in NF1, which negatively regulates the RAS pathway. Knowledge of the genotype-phenotype correlation in this disease is an important tool for prognostic evaluation and early detection of malignant peripheral nerve sheath tumors (MPNST), present in approximately 10% of these patients. We present the case of a teenager with a left jaw MPNST and a previously unreported germline pathogenic variant on NF1.

A Potential Role for Neuroinflammation in ADHD.

Attention deficit hyperactivity disorder (ADHD) is a neurobehavioural disorder in children and adolescents. Although increases in oxidative stress and disturbances of neurotransmitter system such as the dopaminergic and abnormalities in several brain regions have been demonstrated, the pathophysiology of ADHD is not fully understood. Nevertheless, ADHD involves several factors that have been associated with an increase in neuroinflammation.

Antigenic Proteins Shared with Acute Lymphoblastic Leukemia and Neuroblastoma.

Research studies indicate that immunization with protein extracts of , the protozoan parasite that causes Chagas disease, prevents the appearance of tumors in 60% of mice injected with the murine lung carcinoma tumor line. The molecular basis of this process is unknown, although the presence of specific antigens in tumor cells and on the surface of suggests an antiparasitic immune response, with an effective cross-reaction against cancer cells, hence the importance to identify the antigens involved and determine their potential as target cells in anticancer therapy. This study aimed to determine the presence of antigenic proteins of shared with acute lymphoblastic leukemia and neuroblastoma cells.

Glycine Effect on the Expression Profile of Orphan Receptors GPR21, GPR26, GPR39, GPR82 and GPR6 in a Model of Inflammation in 3T3-L1 Cells.

Background: Chronic or low-grade inflammation is a process where various immune cells are recruited from the periphery into adipose tissue. This event gives rise to localised inflammation, in addition to having a close interaction with cardiometabolic pathologies where the mediation of orphan receptors is observed. The aim of this study was to analyse the participation of the orphan receptors GPR21, GPR39, GPR82 and GPR6 in a chronic inflammatory process in 3T3-L1 cells.

Atomoxetine Decreases Mitochondrial Biogenesis, Fission and Fusion In Human Neuron-like Cells But Does Not Alter Antioxidant Defences.

Atomoxetine (ATX) is a presynaptic norepinephrine transporter (NET) inhibitor widely prescribed for attention-deficit/hyperactivity disorder (ADHD) due to its low abuse potential and absence of psychostimulant effects. While NET inhibition is implicated in the clinical response, several additional pharmacoactivities may contribute to clinical efficacy or unwanted side effects. We recently reported that ATX can dose-dependently alter mitochondrial function and cellular redox status.

The prevalence of these diseases leads to an increase in the use of health services. The care models implemented by health systems should provide comprehensive long-term healthcare.

HP0953 - hypothetical virulence factor overexpresion and localization during infection of gastric epithelium.

Background: The high prevalence and persistence of () infection, as well as the diversity of pathologies related to it, suggest that the virulence factors used by this microorganism are varied. Moreover, as its proteome contains 340 hypothetical proteins, it is important to investigate them to completely understand the mechanisms of its virulence and survival. We have previously reported that the hypothetical protein HP0953 is overexpressed during the first hours of adhesion to inert surfaces, under stress conditions, suggesting its role in the environmental survival of this bacterium and perhaps as a virulence factor.

Invasive Fungal Infection Caused by in an Immunocompromised Pediatric Patient with Acute Lymphoblastic Leukemia in Mexico City: A Case Report.

Magnusiomyces capitatus (also denominated “Geotrichum capitatum” and “the teleomorph stage of Saprochaete capitata”) mainly affects immunocompromised patients with hematological malignancies in rare cases of invasive fungal infections (IFIs). Few cases have been reported for pediatric patients with acute lymphoblastic leukemia (ALL), in part because conventional diagnostic methods do not consistently detect M. capitatus in infections.

Overweight and Obesity Are Positively Associated with Serum Copper Levels in Mexican Schoolchildren.

Due to its relationship with oxidative stress and inflammation responses, obesity and its cardiometabolic implications have been related with serum copper (Cu). Hence, we analyzed the association of overweight (OW) and obesity (OB) status and cardiometabolic traits with serum Cu level in Mexican schoolchildren. Anthropometrical data and cardiometabolic traits were analyzed in this cross-sectional study.
