Phylogenetic position of the subfamily Symphrasinae (Insecta: Neuroptera), its intergeneric relationships and evolution of the raptorial condition within Mantispoidea.

The superfamily Mantispoidea (Insecta: Neuroptera) includes the families Berothidae, Rhachiberothidae and Mantispidae. Among these taxa, the last two are collectively known as Raptorial Mantispoidea due to the presence of grasping forelegs for predatory habits. The Mantispidae classically included the subfamilies Symphrasinae, Drepanicinae, Calomantispinae and Mantispinae, yet recent research challenged this classification scheme as well as the monophyly of this family resulting in Symphrasinae being transferred to Rhachiberothidae.

Wing geometric morphometrics is effective to separate sand fly species (Diptera, Psychodidae, Phlebotominae) related with leishmaniasis transmission in Mexico.

Nearly 32 % of sand fly species recorded in Mexico are related to Leishmania transmission. A correct morphological identification of sand flies is essential to improve epidemiological and control strategies. Wing geometric morphometrics (GM) has proven to be a complementary tool for classical taxonomy, allowing us to explore variations in structure and shape between species.

New status of Bichromomyia subspecies (Diptera: Psychodidae: Phlebotominae) based on molecular taxonomy.

The sand fly of the genus Bichromomyia (Galati, 1995) includes 3 subspecies considered vectors of Leishmania, which share high morphological similarity. Through information from the Cytochrome Oxidase Subunit I (COI) gene, we provide complementary evidence to support that Bichromomyia olmeca olmeca, and Bichromomyia olmeca bicolor, should be raised to nominal species status. We recovered specimens of Bi.

Pancreatic β‑cell apoptosis in type 2 diabetes is related to post‑translational modifications of p53 (Review).

Pancreatic β‑cells are the only cells that synthesize insulin to regulate blood glucose levels. Various conditions can affect the mass of pancreatic β‑cells and decrease insulin levels. Diabetes mellitus is a disease characterized by insulin resistance and chronic hyperglycemia, mainly due to the loss of pancreatic β‑cells caused by an increase in the rate of apoptosis.

Surgical approach with minimally invasive intervention in lusoria dysphagia.

The lusoria artery has a prevalence of 0.5-2% in the general population. The abnormal development of the aortic arch forms vascular rings around the trachea and esophagus, causing pressure on them and leading to characteristic symptoms such as chest pain, difficulty breathing, and/or swallowing.

One-Step Synthesis, Crystallography, and Acute Toxicity of Two Boron-Carbohydrate Adducts That Induce Sedation in Mice.

Boronic acids form diester bonds with cis-hydroxyl groups in carbohydrates. The formation of these adducts could impair the physical and chemical properties of precursors, even their biological activity. Two carbohydrate derivatives from d-fructose and d-arabinose and phenylboronic acid were synthesized in a straightforward one-step procedure and chemically characterized via spectroscopy and X-ray diffraction crystallography.

Surveillance of sand flies (Psychodidae, Phlebotominae) from Mexico: Altitudinal and climatic patterns after historical and new geographic records in endemic areas of leishmaniasis.

This study updates knowledge on historical geographic distribution of sand fly species through identifying altitudinal and bioclimatic patterns in leishmaniasis endemic areas in Mexico. We analyze and identify sand fly specimens obtained through national efforts by the Instituto de Diagnóstico y Referencia Epidemiológicos (InDRE, Mexico), collected between 1995 and 2001, 2008-2012, and 2017-2023, and add bibliographic information (427 additional records). After a principal components analysis of WorldClim variables and altitudinal ranges, variables that better explain the distribution of sand fly species were chosen (BIO6, BIO12, and BIO16, explaining 72 % of variation).

Species of the thorny lacewing subfamily Symphrasinae (Neuroptera: Rhachiberothidae) are revised. Prior to this work, 42 species were known in the genera Navás, 1909, Navás, 1928, and Westwood, 1852. Herein, the number of species is increased to 60, 23 of which are newly described.

The sodium borate relieves the hypertrophic damage induced during pregnancy, it improves contractibility, reduces oxidative stress and stimulates cell proliferation.

Introduction: Fetal and postnatal hypertrophy develop in response to such different exposures or illnesses the mother suffers during gestation as anti-infectious and physical agents, obesity, hypertension, diabetes, and even advanced maternal age. This gives rise to high comorbidities in the newborn; therefore, looking for alternatives that contribute to cardiac homeostasis is quite necessary to inhibit the overgrowth of myocytes. Boron-derivative compounds could play a key role in exerting a repairing effect on chronic cardiac damage induced during gestation.

Pancreatic β-Cell Apoptosis in Normoglycemic Rats is Due to Mitochondrial Translocation of p53-Induced by the Consumption of Sugar-Sweetened Beverages.

Overstimulation of pancreatic β-cells can lead to dysfunction and death, prior to the clinical manifestations of type 2 diabetes (T2D). The excessive consumption of carbohydrates induces metabolic alterations that can affect the functions of the β-cells and cause their death. We analyzed the role of p53 in pancreatic β cell death in carbohydrate-supplemented Sprague Dawley rats.

The genus Enderlein, 1910 (Neuroptera, Mantispidae) in French Guiana.

The genus Enderlein, 1910 is a remarkable group of mantidflies (Neuroptera: Mantispidae: Mantispinae) distributed from Canada to Argentina, including parts of the Caribbean. This genus comprises nine valid extant species plus an extinct species from the late Oligocene of France. Species exhibit Batesian mimicry with vespid wasps (Vespidae).

Isolation and Identification of Mesenchymal Stem Cells Derived from Adipose Tissue of Sprague Dawley Rats.

Adult mesenchymal cells have revolutionized molecular and cell biology in recent decades. They can differentiate into different specialized cell types, in addition to their great capacity for self-renewal, migration, and proliferation. Adipose tissue is one of the least invasive and most accessible sources of mesenchymal cells.

After a decade, a new Venezuelan species of Latreille (Megaloptera, Corydalidae, Corydalinae) is discovered.

A new species of dobsonfly from Venezuela, Martins, Azevêdo, Hamada & Contreras, , was discovered a decade after the last description of a species of this genus in the country. The new species is morphologically similar to Contreras-Ramos & von der Dunk, sharing a uniform reddish coloration of body and wings and similar male genitalic structures. Likewise, it shares this particular coloration with Contreras-Ramos but the genitalic structure fits within the Contreras-Ramos species group.

Cardiac transplantation due to hemochromatosis. A pediatric case report.

Hemochromatosis is a disease characterized by excess iron stores in multiple organs, including the liver, pancreas, skin, and heart. The infiltration of the heart is an important factor in morbidity and mortality. Here we describe the case of a pediatric patient with end-stage heart failure who required a heart transplantation, with no complications.

The metabolic phenotype of the patient influences the reduction in carotid intima-media thickness achieved following metabolic surgery.

Objectives: To determine whether metabolic phenotype is associated with the change in carotid intima-media thickness (CIMT) in patients undergoing bariatric /metabolic surgery (BMS).

Methods: We performed a case-control study of BMS candidates who had metabolically unhealthy obesity (MUO) or metabolically healthy obesity (MHO). We measured the change in CIMT during the 9 months following BMS.

Diversity of Lacewings (Neuroptera) in an Altitudinal Gradient of the Tacaná Volcano, Southern Mexico.

Neuroptera is an order of insects with a moderate diversity of species numbers yet a high between-family morphological diversity, which has a significant ecological role as a predator. However, there are few studies focused on describing changes in species diversity along environmental gradients. We evaluated changes in the alpha and beta diversity of species and the higher taxa in Neuroptera communities in the Tacaná Volcano in southern Mexico.

NOTCH expression variability and relapse of breast cancer in high-risk groups.

Background: In regards to breast cancer (BC), survival or disease-free periods are still compromised mainly in Triple Negative (TN) and HER2 tumors. The participation of estrogen receptor (ER) has been reported as crucial in the signaling pathways, including the NOTCH pathway. The study was aimed to evaluate the expression of NOTCH1 and NOTCH3 in BC and its relationship with the presence of ER, as well as with relapses.

A systematic review on the role of MSC-derived exosomal miRNAs in the treatment of heart failure.

Background: Heart failure (HF) is a deeply serious clinical problem that remains unsolved. Many reports highlight the cardioprotective properties of mesenchymal stem cells (MSCs), the factors contained in their secretome being particularly important for this function; these include the exosomal miRNAs (exo-miRNAs) secreted with or without stimulus which can modulate various biological processes. In search of new paradigms in heart failure, we wondered whether MSC-derived exosomal microRNAs could play a role in the management of clinical patients.

Similar pattern, different paths: tracing the biogeographical history of Megaloptera (Insecta: Neuropterida) using mitochondrial phylogenomics.

The sequential breakup of the supercontinent Pangaea since the Middle Jurassic is one of the crucial factors that has driven the biogeographical patterns of terrestrial biotas. Despite decades of effort searching for concordant patterns between diversification and continental fragmentation among taxonomic groups, increasing evidence has revealed more complex and idiosyncratic scenarios resulting from a mixture of vicariance, dispersal and extinction. Aquatic insects with discreet ecological requirements, low vagility and disjunct distributions represent a valuable model for testing biogeographical hypotheses by reconstructing their distribution patterns and temporal divergences.

NK Cell Subpopulation Is Altered and the Expression of TLR1 and TLR9 Is Decreased in Patients with Acute Lymphoblastic Leukemia.

NK cells represent a heterogeneous subpopulation of lymphocytes of the innate immune system, which possess powerful antitumor activity. NK cells exhibit their function through a complex collection of receptors that act synergistically to recognize, regulate, or amplify the immune response. TLRs allow cells to detect PAMPs, MAMPs, or DAMPs, which are essential for the initiation of the immune response.

Changes in miR 21 and 23b expression in postnatal hypertrophic heart derived from gestational diabetes precede dilated cardiomyopathy.

Gestational diabetes mellitus (GDM) increases the risk of fetal congenital ventricular hypertrophic cardiomyopathy (HCM). We explored the effects and mechanisms of the postnatal progression of fetal hypertrophic failure in rat pups with STZ-induced Gestational Diabetes (GD). The hearts of rat pups (newborn [NB], 8, 15, 25 and 35 days postnatal) were obtained.
