Distinct Immunophenotypes in the DNA Index-Based Stratification of Pediatric B-Cell Acute Lymphoblastic Leukemia.

Background/objectives: B-cell acute lymphoblastic leukemia (B-ALL) presents a challenge in hematological malignancies due to its heterogeneity, which impacts treatment outcomes. Stratification based on the DNA index (DNAi) categorizes patients into favorable prognosis (hyperploid), standard prognosis (normoploid), and uncertain or poor prognosis (hypoploid) groups. In this study, we explored whether specific immunophenotypic markers are associated with each DNAi-based group and their potential connection to prognostic categories, aiming to provide new insights that may contribute to a better understanding of prognosis in B-ALL.

Prevalence of sexually risky behaviors among Mexican medical students.

University students are at high risk of sexually transmitted infections due to the lack of adequate sexual education, as well as multiple associated factors, which lead to risky sexual practices. It is important to update data about sexual behaviors to identify the main factors associated with sexually risky behaviors. The present study aimed to evaluate the current prevalence of sexually risky practices in medical students.

Identification of Compound Heterozygous Gene Variants in Two Mexican Families with Ellis-van Creveld Syndrome.

Background: Ellis-van Creveld syndrome (EvCS) is an autosomal recessive ciliopathy with a disproportionate short stature, polydactyly, dystrophic nails, oral defects, and cardiac anomalies. It is caused by pathogenic variants in the or genes. To obtain further insight into the genetics of EvCS, we identified the genetic defect for the gene in two Mexican patients.

Alzheimer's Disease: An Updated Overview of Its Genetics.

Alzheimer's disease (AD) is the most common neurodegenerative disease in the world. It is classified as familial and sporadic. The dominant familial or autosomal presentation represents 1-5% of the total number of cases.

Antifungal Activity of Mexican Propolis on Clinical Isolates of Species.

Infections caused by micro-organisms of the genus are becoming a growing health problem worldwide. These fungi are opportunistic commensals that can produce infections-clinically known as candidiasis-in immunocompromised individuals. The indiscriminate use of different anti-fungal treatments has triggered the resistance of species to currently used therapies.

Human papillomavirus infection and seroprevalence among female university students in Mexico.

Human papillomavirus (HPV) is one of the most common causes of sexually transmitted diseases, and the main etiology of cervical cancer. This study was aimed to assess type-specific cervical HPV prevalence and their association with HPV-specific antibodies in a cohort of female university students. HPV genotyping was performed by amplifying and sequencing a fragment of the L1 protein.

Flavonoids Present in Propolis in the Battle against Photoaging and Psoriasis.

The skin is the main external organ. It protects against different types of potentially harmful agents, such as pathogens, or physical factors, such as radiation. Skin disorders are very diverse, and some of them lack adequate and accessible treatment.

Effects of Propolis on Infectious Diseases of Medical Relevance.

Infectious diseases are a significant problem affecting the public health and economic stability of societies all over the world. Treatment is available for most of these diseases; however, many pathogens have developed resistance to drugs, necessitating the development of new therapies with chemical agents, which can have serious side effects and high toxicity. In addition, the severity and aggressiveness of emerging and re-emerging diseases, such as pandemics caused by viral agents, have led to the priority of investigating new therapies to complement the treatment of different infectious diseases.

Familial Hypercholesterolemia: Update and Review.

Knowledge of epidemiology, genetic etiopathogenesis, diagnostic criteria, and management of familial hypercholesterolemia have increased in the last two decades. Several population studies have shown that familial hypercholesterolemia is more frequent than previously thought, making this entity the most common metabolic disease with monogenic inheritance in the world. Identification of causal heterozygous pathogenic variants in LDLR, APOB, and PCSK9 genes has increased diagnostic accuracy of classical criteria (extreme hypercholesterolemia, personal / family history of premature coronary artery disease or other cardiovascular diseases).

Biomedical Properties of Propolis on Diverse Chronic Diseases and Its Potential Applications and Health Benefits.

The use of alternative medicine products has increased tremendously in recent decades and it is estimated that approximately 80% of patients globally depend on them for some part of their primary health care. Propolis is a beekeeping product widely used in alternative medicine. It is a natural resinous product that bees collect from various plants and mix with beeswax and salivary enzymes and comprises a complex mixture of compounds.

Hypohidrotic ectodermal dysplasia: clinical and molecular review.

Hypohidrotic Ectodermal Dysplasia (HED) is a genetic human disorder which affects structures of ectodermal origin. Although there are autosomal recessive and dominant forms, X-linked (XL) is the most frequent form of the disease. This XL-HED phenotype is associated with mutations in the gene encoding the transmembrane protein ectodysplasin-1 (EDA1), a member of the TNFα-related signaling pathway.

Polymorphism rs2275913 of Interleukin-17A is related to more intensive therapy with disease-modifying anti rheumatic drugs in Mexican patients with Rheumatoid Arthritis.

Aim: The study has two aims: 1) to evaluate the association of IL-17 polymorphism rs2275913 with RA severity and 2) to evaluate if this particular SNP is associated with susceptibility for RA in Mexican patients.

Methods: Seventy-six RA patients and ninety-four healthy controls were included in the study. RA patients were evaluated according to DAS 28.

Arsenic-induced S phase cell cycle lengthening is associated with ROS generation, p53 signaling and CDC25A expression.

Cellular response to arsenic is strongly dependent on p53 functional status. Primarily arresting the cell cycle in G1 or G2/M phases, arsenic treatment also induces an increase in the S-phase time in wild-type p53 cells. In contrast, cells with a non-functional p53 display only a subtle increase in the S phase, indicating arsenic differentially affects the cell cycle depending on p53 status.

Novel missense mutation in the EDA1 gene identified in a family with hypohidrotic ectodermal dysplasia.

Background: Hypohidrotic ectodermal dysplasia (HED) is a human genetic disorder that affects structures of ectodermal origin such as hair, teeth, and sweat glands. Although there are autosomal recessive and dominant forms, X-linked (XL) is the most frequent form of the disease. This XL-HED phenotype is associated with mutations in the gene encoding the transmembrane protein ectodysplasin-1 (EDA1).
