Summary: This study investigates the metabolite composition of yak milk and its role in hypoxic stress tolerance, comparing it to human milk. The results show that yak milk relies on certain essential amino acids to tolerate hypoxic stress, while human milk utilizes neuroprotective effects of non-essential amino acids or derivates. Additionally, metabolites related to hypoxic stress are more abundant in yak colostrum compared to yak mature milk.

Summary: Human milk is rich in miRNAs and exosomes, which play significant roles in neurodevelopment and normal function. Through analyzing human breast milk samples, we identified 132 different miRNAs, 69 of which showed significant differential expression. These miRNAs are involved in gene regulation related to synaptic activity and neuron projection morphogenesis. Our findings suggest that human milk can transmit molecular and biological information for brain development.

Summary: During pregnancy, the immune system of pregnant women and their offspring must find a balance between fetal tolerance and protection against pathogens. This delicate balance often leads to increased susceptibility to infections. In this study, it was found that offspring from mice infected with influenza A virus (IAV) were significantly protected against IAV infection, thanks to the elevated levels of maternal serum IgG1. The enhanced host resistance was only observed in mice born to and nursed by IAV-infected mothers, indicating the importance of maternal IgG1 from both the placenta and breast milk in providing prolonged protection against IAV infection in offspring.

Summary: Our understanding of nucleotides in human milk has been limited compared to other components such as fatty acids, proteins, and oligosaccharides. This review examines literature from the past 25 years to provide an updated overview of nucleotide concentrations in breast milk across lactational stages and regions. The levels of nucleotides in breast milk vary greatly among individual mothers, lactation stages, and potentially influenced by factors like time of day, season, and diet. While levels of free nucleotides differ between studies conducted in different regions, total potentially available nucleotides show no apparent regional differences. Recent clinical studies suggest benefits of nucleotide supplementation in infant formula. The information from this review may contribute to the development of formula products for infants at different stages of development.

Summary: Bacterial infections, particularly mastitis, in small ruminants are an important economic issue. However, there is limited understanding of the microbiota and changes during infection. Sequencing of the 16S rRNA gene has been useful in describing the dairy microbiome, revealing various phyla and genera, though consensus on predominant phyla or genera is lacking. Further research is needed to compare microbial communities between different lactation methods and milk types, particularly in meat-oriented breeds, to guide the development of alternative strategies for mastitis control. Probiotics, such as LAB, have shown promise as antibiotic-free strategies and warrant further investigation in small ruminants.

Summary: Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on ecosystems and human health. A global-scale study of API pollution in rivers highlights the highest concentrations in sub-Saharan Africa, south Asia, and South America, primarily in low- to middle-income countries with poor wastewater and waste management infrastructure. The most frequently detected APIs include carbamazepine, metformin, and caffeine, with some concentrations exceeding safe levels for aquatic organisms. Pharmaceutical pollution poses a global threat to environmental and human health and has implications for achieving the United Nations Sustainable Development Goals.

Summary: This umbrella review synthesized the findings of selected reviews on the non-carcinogenic health effects of exposure to polycyclic aromatic hydrocarbons (PAHs) in human populations. The review found associations between PAH exposure and adverse health outcomes such as lowered IQ, impaired cognitive development, decreased pulmonary function, hypertension, preterm birth, and delayed fetal growth. However, the associations were inconsistent or null for attention-deficit/hyperactivity disorder, behavioral problems, asthma, and hypertension (only in occupational setting). More research is needed to investigate the effects of PAH exposure on respiratory diseases, cardiovascular diseases, obesity, and infertility. Challenges in exposure assessment were identified, including exposure to mixtures with other chemicals and limited coverage of biomonitoring data.

Summary: In this systematic review, the authors examined the presence and potential effects of DINP and DIDP, two plasticizers used as alternatives to DEHP, in various environmental media, foods, consumer products, and human populations. The results indicate that DINP and DIDP are widely present in indoor environments, diets, and children's products. While the levels of DINP exposure were found to be relatively lower compared to DEHP, it still exhibited similar endocrine disruption potentials, particularly among males and pregnant women. There are knowledge gaps regarding the exposure of DIDP in the human population.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
