Skin wounds, due to their high vulnerability to infections, represent a significant public health issue. These wounds are not only disabling but also entail costly treatments and slow recovery. Consequently, it is crucial to implement new treatments based on bioactive and natural antimicrobial compounds utilizing fibers, polymers, hydrocolloids, and hydrogels to control potential infections and promote wound healing.

Breast milk is widely recognized as the primary source of nourishment for newborns, making it an unparalleled and indispensable provider of essential nutrients, microbiological components, immunological factors, and energy content. To investigate this further, a cohort comprising 254 breastfeeding women participated in interviews, and milk samples were aseptically collected for subsequent analysis involving bromatological, microbiological, and clinical analysis. The investigation focused on the identification of specific microorganisms in breast milk and their susceptibility to the exposure of toxic substances and controlled medications.

Breast milk (BM) is a constantly changing fluid that represents the primary source of nutrition for newborns. It is widely recognized that breastfeeding provides benefits for both the child and the mother, including a lower risk of ovarian and breast cancer, type 2 diabetes mellitus, decreased blood pressure, and more. In infants, breastfeeding has been correlated with a lower risk of infectious diseases, obesity, lower blood pressure, and decreased incidence of respiratory infections, diabetes, and asthma.

The human milk microbiota (HMM) of healthy women can vary substantially, as demonstrated by recent advances in DNA sequencing technology. However, the method used to extract genomic DNA (gDNA) from these samples may impact the observed variations and potentially bias the microbiological reconstruction. Therefore, it is important to use a DNA extraction method that is able to effectively isolate gDNA from a diverse range of microorganisms.

Preterm infants are at high risk of infection due to opportunistic bacteria as , causing infections among infants in neonatal intensive care units. Human lactoferrin (hLf) is a multifunctional protein and one of the most abundant in breast milk, and plays an important role in prevention of different infections in neonates. This work offers a strategy to obtain a lyophilisate of purified lactoferrin from breast milk.

Introduction: breast milk (MH) contains nutrients and bioactive compounds for child development, including probiotic bacteria, which contribute to intestinal maturation. This benefit accompanies the individual until adulthood. There are new methods such as spray drying that give this compound a good conservation without loss of microbiota.

Introduction: in April 2002, the National Food Authority of Sweden published a study in which the presence of a carcinogen was reported for the first time in experimental animals, and was identified as acrylamide. Various studies have shown that the β-glucans of Pleurotus ostreatus have diverse biological properties including antioxidant and anticancer activities. Methods: β-glucans were obtained by alkaline-acid hydrolysis from Pleurotus ostreatus, and their content was characterized by liquid chromatography.

The use of antimicrobial agents within a matrix, specifically layered compounds, is of growing interest for reducing contamination due to food borne pathogens and deteriorative microorganisms, one of the main health problems worldwide. In this study, zinc layered hydroxide nanoparticles were synthesized as a matrix for nisin immobilization. Layered materials were characterized by X-ray diffraction, Fourier-Transform Infrared and Ultra Violet-Visible spectra, Scanning Electron Microscopy, and by Thermogravimetric Analysis.

Introduction: acrylamide is formed in food through Maillard's reaction during thermal processing, and has been shown to be neurotoxic in humans, and a possible carcinogen. Studies have shown that β-glucans from Pleurotus ostreatus have diverse biological properties such as antioxidant and anticancer activities. Objective: the aim of this work was to evaluate the protective effect of β-glucans from Pleurotus ostreatus against the harmful effects of acrylamide consumption in mice.

Introduction: breast milk is the first fundamental food of newborns and it provides all the sources of energy, nutrients and the immunological protection they need during their first months of life. Unfortunately, there are specific circumstances that imply that the mother cannot feed her baby correctly, since the mother's nutritional needs differ to a certain extent during different periods of life. Especially in breastfeeding, since nutritional needs are increased, due to the loss of nutrients, first by colostrum and then by breast milk.

Introduction: This study analyzes the effect on the content of immunoglobulins and C3 complement of freeze drying after pasteurization by three different methods in mature human milk (MHM).

Objective: Freeze drying is proposed as a complementary method for the maintenance of MHM therapeutic properties with greater validity.

Methods: This was a descriptive study in which MHM samples were obtained.

In this research removal of NH-N, NO-N and PO-P nutrients from municipal wastewater was studied, using Chlorella vulgaris, Pseudomonas putida, Bacillus cereus and an artificial consortium of them. The objective is to analyze the performance of these microorganisms and their consortium, which has not been previously studied for nutrient removal in municipal wastewater. A model wastewater was prepared simulating the physicochemical characteristics found at the wastewater plant in Chapala, Mexico.
