Human milk oligosaccharides (HMOs) are complex glycans that are the third largest solid component in human milk. It has attracted great interest in recent years due to their critical role in boosting infant health. These oligosaccharides play an important role in a variety of physiological processes, such as shaping the infant gut microbiome, preventing pathogenic infections and promoting the development of immune system. However, limited availability of HMOs hampered their use in food and medical areas. Moreover, most of the HMOs are unique to human milk and difficult to isolate. The strategies, chemical synthesis, whole-cell fermentation, and purification from human milk, have their advantages and come with their own challenges. In this review, we examined the remarkable progress that has been made in the enzymatic and chemoenzymatic synthesis of HMOs, and discussed the challenges and opportunities in large-scale synthesis of HMOs.

For decades, bovine mastitis and milk quality have been a focus area for research, agricultural extension, and dairy processors worldwide, yet employee management as a factor in udder health management has received limited attention. This is mainly because the focus has previously been on more classical areas covered by the National Mastitis Council Mastitis Control Program (NMC 10-point plan) in English-speaking countries. Therefore, we wanted more background information on employee management on dairy farms, to identify the human factor of udder health management.

Abrin, a toxin of the rosary pea plant (), has been implicated as causing an autoimmune demyelinating disease in humans, but the exact mechanisms responsible for the induction of these demyelinating conditions are still unknown. Certain superantigen microbial toxins such as Staphylococcus enterotoxin type A, type D, type E or streptococcal pyrogenic exotoxin type C also lead to various diseases including autoimmune disorders of the nervous system. Here, the effect of abrin toxin on the immune reaction was studied in human CD4 T-cell lines, and its inhibition of protein synthesis in kidney cells.

Establishment of the gut microbiota during infancy is critical for host health with long-lasting implications. In this orchestrated process, microbial assembly is influenced by an increasing number of genetic and environmental factors, among which breastfeeding is considered as one of the most significant drivers for infant gut microbiota development. As the optimal diet for the infants, maternal milk provides numerous nutritional, microbial, and bioactive components to ensure the most adequate microbial growth and development of a 'healthy' gut microbiota during early life.

Background: The interaction between the human breast milk microbiota and human milk oligosaccharides (HMOs) plays a crucial role in the healthy growth and development of infants. We aimed to clarify the link between the breast milk microbiota and HMOs at two stages of lactation.
Methods: The microbiota and HMOs of 20 colostrum samples (C group, 1-5 days postpartum) and 20 mature milk samples (S group, 42 days postpartum) collected from postpartum mothers were analyzed using 16S rRNA gene high-throughput sequencing and high-performance liquid chromatography-tandem mass spectrometry.

Individuals who are at risk of not achieving a full milk supply are often overlooked in scientific literature. There is available guidance to help establish an adequate milk supply for healthy individuals experiencing a physiologic labor and birth, and there are robust recommendations for the lactating parents of small, sick, and preterm newborns to ensure that these newborns can receive human milk. Missing from the literature are clinical practice guidelines that address the preexisting health, pregnancy, birth, or newborn-related risk factors for suboptimal lactation.
