Background: animal studies have shown that enteral stimuli play an important role in modulating gut-associated lymphoid tissue.

Objective: the main objectives of this study were 1) to evaluate the effect of 3-day fasting on secretory immunoglobulin A (S-IgA) in parotid saliva and 2) to determine the levels of lymphotoxin (LT) transcription in peripheral blood mononuclear cells (PBMNC) from healthy volunteers as a proxy for studying GALT health.

Methods: these adult volunteers had fasted for three days as part of a cultural ritual.

An intense 60-day weight-loss course leads to an 18 kg body weight reduction and metabolic reprogramming of soldiers with obesity.

Soldiers of the Mexican Army with obesity were subjected to an intense 60-day weight-loss course consisting of a controlled diet, daily physical training, and psychological sessions. The nutritional treatment followed the European Society of Cardiology (ESC) recommendations, incorporating elements of the traditional diet in the nutritional intervention. The total energy intake was reduced by 200 kcal every 20 days, starting with 1,800 kcal and ending with 1,400 kcal daily.

Effects of prebiotics, probiotics, and synbiotics on the prevention and treatment of cervical cancer: Mexican consensus and recommendations.

Gut microbiota plays a crucial role in modulating immune responses, including effector response to infection and surveillance of tumors. This article summarizes the current scientific evidence on the effects of supplementation with prebiotics, probiotics, and synbiotics on high-risk human papillomavirus (HPV) infections, precancerous lesions, and various stages of cervical cancer development and treatment while also examining the underlying molecular pathways involved. Our findings indicate that a higher dietary fiber intake is associated with a reduced risk of HPV infection, while certain probiotics have shown promising results in clearing HPV-related lesions.

Evidence of impaired H-reflex and H-reflex rate-dependent depression in diabetes, prediabetes and obesity: a mini-review.

Diabetes Mellitus is a public health problem associated with complications such as neuropathy; however, it has been proposed that these may begin to develop during prediabetes and may also be present in persons with obesity. Diabetic peripheral neuropathy is the presence of signs and/or symptoms of peripheral nerve dysfunction in people living with diabetes, which increases the risk of developing complications and has a deleterious impact on quality of life. As part of the therapeutic protocol for diabetes, screening tests to identify peripheral neuropathy are suggested, however, there are no recommendations for people with prediabetes and obesity without symptoms such as pain, numbness, or paresthesias.

Effects of on a Model of Sexual Dysfunction in Streptozotocin-Induced Diabetic Male Rats.

(SM) is a cyanobacterium that has a long history of being used as human food. In recent years, several investigations have shown its beneficial biological effects, among which its antioxidant capacity has been highlighted. The purpose of this study was to evaluate the effects of SM on body weight, glycemia, sexual behavior, sperm quality, testosterone levels, sex organ weights, and the activity of antioxidant enzymes in diabetic male rats (a disease characterized by an increase in reactive oxygen species).

Anthocyanins: Potential Therapeutic Approaches towards Obesity and Diabetes Mellitus Type 2.

Overweight and obesity are present in about three-quarters of the adult population in Mexico. The inflammatory mechanisms subjacent to visceral white adipose tissue are accountable for the initiation and development of cardiometabolic alterations, including type 2 diabetes. Lifestyle changes are pillars within its therapeutics and, thus, current dietary modifications should include not only hypocaloric prescriptions with balanced macronutrient intake, preferably by increasing the amount of whole grains, fruits, vegetables, nuts and legumes, but in concomitance, bioactive substances, such as anthocyanins, have been correlated with lower incidence of this disease.

Memory improvement in senile rats after prebiotic and probiotic supplementation is not induced by GLP-1.

Introduction: The mechanism underlying the memory improvement induced by prebiotic and probiotic supplementation remains unclear. Glucagon-like peptide type 1 (GLP-1) could play an important role since it is induced by prebiotics and enhances memory and learning.

Aims: We correlated the levels of GLP-1 with spatial memory in senile animals to determine its role in memory improvement after prebiotic and probiotic supplementation.

The effect of plant-based diets on meta-inflammation and associated cardiometabolic disorders: a review.

Meta-inflammation is a chronic, low-grade state of inflammation secondary to cardiometabolic disorders related to overweight (OW), obesity (OB), consumption of poor nutritional and hypercaloric diets with excessive amounts of lipids and sugars. It can lead to severe metabolic and cardiovascular diseases. Several studies have reported that plant-based diets (PBDs) can be a useful non-pharmacological therapeutic tool for the prevention and treatment of meta-inflammation, since it has been reported that patients following PBDs have lower serum levels of proinflammatory markers, a reduction in weight, and an overall healthier lipid profile.

Potential applications of cocoa () on diabetic neuropathy: mini-review.

Diabetes Mellitus is a highly prevalent disease in Mexico and in the world, among whose complications is diabetic neuropathy. DN is a group of disorders that present signs and/or symptoms of peripheral nerve dysfunction and have different clinical manifestations in both peripheral neuropathy and autonomic neuropathy. As a part of the mechanisms by which DN develops, oxidative stress and inflammation have been described.

Phycobiliproteins extract from Spirulina protects against single-dose cadmium-induced reproductive toxicity in male mice.

Cadmium (Cd) is known for its many toxic effects on male population such as hypogonadism and fertility difficulties, which are oftenly associated with oxidative stress. As beneficial food, Spirulina(Sp) has been proved efficient against the heavy metal toxicity. This capacity can be associated with its phycobiliproteins (PBP).

Phycobiliproteins Ameliorate Gonadal Toxicity in Male Mice Treated with Cyclophosphamide.

Cyclophosphamide (CP)-which is used to treat autoimmune diseases and cancer-is related to gonadotoxicity attributed to oxidative stress. As phycobiliproteins (PBPs) are strong antioxidants that are unexplored as protective agents against male gonadotoxicity, our work aimed to investigate the effects of PBP crude extract on testicular damage and sperm parameter alterations caused by CP in mice. Three doses of PBP (50, 100, and 200 mg/kg) were tested in the experimental groups ( = 8 per group), administered concomitantly with 100 mg/kg CP.

The effect of enteral stimulation on the immune response of the intestinal mucosa and its application in nutritional support.

The intestine plays a fundamental role as a regulator of the mucosal immune response, mostly through the production and secretion of secretory Immunoglobulin A (sIgA) by the gut-associated lymphoid tissue (GALT). Enteral stimulation, a balance between the commensal microbiota and pathogenic microorganisms, in addition to an adequate nutritional status is required for the optimal immune function of the intestine. Fasting subjects or those supported only with parenteral nutrition, show a progressive anatomical and physiological deterioration of the GALT, triggering a series of alterations resulting in a decrease in the intestinal immune response, modification in the type of microbiota, and changes that lead to or aggravate malnutrition.

Effects of a Low-Dose Spirulina/Turmeric Supplement on Cardiometabolic and Antioxidant Serum Markers of Patients With Abdominal Obesity.

Obesity is one of the greatest public health problems worldwide. It is associated with underlying low-grade inflammation, thus is a risk factor for the development of cardiometabolic alterations. Functional foods, such as spirulina and turmeric, in the form of nutraceutics have been considered to exert not only an antioxidant effect but also modulate mechanisms in the metabolic pathways underlying cardiometabolic disruptions.

Traditional Mexican foods as functional agents in the treatment of cardiometabolic risk factors.

Major cardiometabolic risk phenotypes include insulin resistance (IR), hyperinsulinemia, overweight, obesity and dyslipidemia, which contribute to the current prevalent chronic disease pandemia worldwide. Among traditional treatments, dietary habits represent one of the most difficult and controversial aspects to implement in handling metabolic disturbances. The use of herbal remedies by latinos and hispanics, as part of self-care of metabolic diseases has been well documented in several studies, mainly because they are "natural", consistent with their culture, family-related, accessible, and affordable.

Hoffa's Fat Pad-associated Solitary Neurofibroma as the Cause of Anterior Knee Pain: A Case Report.

Introduction: Infrapatellar peripheral neural tumors, particularly neurofibromas, are rather rare entities reported in the literature. They are slow-growing lesions that usually do not exhibit clinical manifestations other than interspecific swelling or pain; hence, their diagnosis can be quite challenging. Therefore, scrutiny should include not only traditional clinical assessment and imaging but also more specific molecular biology techniques, such as immunohistochemistry.

Effects of omega-3 fatty acids supplementation on neoadjuvant chemotherapy-induced toxicity in patients with locally advanced breast cancer: a randomized, controlled, double-blinded clinical trial.

Background: antineoplastic treatment for locally advanced breast cancer (LABC) includes neodjuvant chemotherapy (NeoCT). However, side effects occur frequently, affecting the functional capacity and quality of life of patients as a result of the proinflammatory state of this therapy. In this work, omega-3 polyunsaturated fatty acids (PUFA Ω-3) were administered as they have been reported to modulate some molecular pathways such as nuclear factor-kappa B (NF-κB), which is associated with toxicity secondary to the administration of anthracyclines.

Probiotics and Prebiotics as a Therapeutic Strategy to Improve Memory in a Model of Middle-Aged Rats.

Aging is associated with morphological, physiological and metabolic changes, leading to multiorgan degenerative pathologies, such as cognitive function decline. It has been suggested that memory loss also involves a decrease in neurotrophic factors, including brain-derived neurotrophic factor (BDNF). In recent years, microbiota has been proposed as an essential player in brain development, as it is believed to activate BDNF secretion through butyrate production.

A randomized, placebo-controlled, double-blind study on the effects of (-)-epicatechin on the triglyceride/HDLc ratio and cardiometabolic profile of subjects with hypertriglyceridemia: Unique in vitro effects.

Background: Cardiometabolic disruptions such as insulin resistance, obesity, high blood pressure, hyperglycemia, and dyslipidemias, are known to increase the risk for cardiovascular and metabolic diseases such as type 2 diabetes mellitus and atherosclerosis. Several screening tools for assessing cardiometabolic risk have been developed including the TG/HDLc ratio, which has been, demonstrated to possess a strong association with insulin resistance and coronary disease. Dietary modifications, together with regular moderate exercise have proven to be effective in attenuating cardiometabolic disruptions.

Is Local Nitric Oxide Availability Responsible for Myocardial Salvage after Remote Preconditioning?

Background: Remote ischemic preconditioning (RIPC) represents an attractive therapy for myocardial protection, particularly when ischemic events can be anticipated. Although several hypothetic mechanisms have been proposed, no definite molecular pathways have been elucidated.

Objective: We evaluated the effect of brachial circulation cuff occlusion on myocardial ischemic tolerance, necrosis, and nitric oxide (NO) in patients with ischemic heart disease undergoing elective percutaneous coronary interventions (PCI).

New Dietary Supplements for Obesity: What We Currently Know.

Obesity and its associated cardiometabolic alterations currently are considered an epidemic; thus, their treatment is of major importance. The cornerstone for such treatment involves therapeutic lifestyle changes; however, the vast majority of cases fail and/or significant weight loss is maintained only in the short term because of lack of compliance. The popularity of dietary supplements for weight management has increased, and a wide variety of these products are available over the counter.

Preclinical antitoxic properties of Spirulina (Arthrospira).

Context: Spirulina (Arthrospira) exerts a wide spectrum of pharmacological activities which are mainly attributed to its antioxidant effect. However, Spirulina has also been reported (both in preclinical and in clinical scenarios) to exhibit other bioactive effects, including an antitoxic potential.

Objective: We performed a systematic review of the literature, conducted in TOXNET, PubMed/MEDLINE, and Science Direct-Scopus; all available years were included.

OBESITY PHENOTYPES IN URBAN MIDDLE-CLASS COHORTS; THE PRIT-LINDAVISTA MERGING EVIDENCE IN MEXICO: THE OPUS PRIME STUDY.

Background And Aims: even though overweight and obesity (O/O) are stated diseases, there is still a claim for a so-called "healthy obese" phenotype. Only few reports have explored the presence of different metabolic phenotypes along the body mass index (BMI) range and their corresponding associations to cardiovascular risks.

Methods: as of BMI, and according to the presence of metabolic syndrome (MS) features (waist circumference, blood pressure, fasting glycemia, and lipid profile), phenotypes were determined.
