Maternal Allergic Disease Phenotype and Infant Birth Season Influence the Human Milk Microbiome.

Early infancy is a critical period for immune development. In addition to being the primary food source during early infancy, human milk also provides multiple bioactive components that shape the infant gut microbiome and immune system and provides a constant source of exposure to maternal microbiota. Given the potential interplay between allergic diseases and the human microbiome, this study aimed to characterise the milk microbiome of allergic mothers.

Bi-allelic variants in DAP3 result in reduced assembly of the mitoribosomal small subunit with altered apoptosis and a Perrault-syndrome-spectrum phenotype.

The mitochondrial ribosome (mitoribosome) synthesizes 13 protein subunits of the oxidative phosphorylation system encoded by the mitochondrial genome. The mitoribosome is composed of 12S rRNA, 16S rRNA, and 82 mitoribosomal proteins encoded by nuclear genes. To date, variants in 12 genes encoding mitoribosomal proteins are associated with rare monogenic disorders and frequently show combined oxidative phosphorylation deficiency.

Biallelic variants in cause variable clinical presentations, including sensorineural hearing loss, leukodystrophy, and ovarian insufficiency.

Combined oxidative phosphorylation deficiency (COXPD) is a rare multisystem disorder which is clinically and genetically heterogeneous. Genome sequencing identified biallelic variants in individuals from five unrelated families with presentations ranging from Perrault syndrome (primary ovarian insufficiency and sensorineural hearing loss) to severe childhood onset of leukodystrophy, learning disability, microcephaly and retinal dystrophy. Complexome profiling of fibroblasts from affected individuals revealed reduced levels of the small and, a more pronounced reduction of, the large mitochondrial ribosomal subunits.

Unexpected Requirement of Small Amino Acids at Position 183 for DNA Binding in the Escherichia coli cAMP Receptor Protein.

The Escherichia coli cAMP receptor protein (CRP) relies on the F-helix, the recognition helix of the helix-turn-helix motif, for DNA binding. The importance of the CRP F-helix in DNA binding is well-established, yet there is little information on the roles of its non-base-contacting residues. Here, we show that a CRP F-helix position occupied by a non-base-contacting residue Val183 bears an unexpected importance in DNA binding.

Lateral Extra-articular Tenodesis With Cortical Suspensory Femoral Fixation and Suture Tape Augmentation.

This article aims to provide a new surgical technique for rotational instability in the setting of anterior cruciate ligament rupture. Two main groups of surgical procedures can be identified in the treatment of anterolateral knee instability: lateral extra-articular tenodesis and anterolateral ligament reconstruction. Although the importance of anterior cruciate ligament reconstruction in anterolateral complex injuries is well known, the superiority of lateral extra-articular tenodesis over anterolateral ligament reconstruction or vice versa has not yet been shown.

Milk microbiome transplantation: recolonizing donor milk with mother's own milk microbiota.

Donor human milk (DHM) provides myriad nutritional and immunological benefits for preterm and low birthweight infants. However, pasteurization leaves DHM devoid of potentially beneficial milk microbiota. In the present study, we performed milk microbiome transplantation from freshly collected mother's own milk (MOM) into pasteurized DHM.

NK cell-triggered CCL5/IFNγ-CXCL9/10 axis underlies the clinical efficacy of neoadjuvant anti-HER2 antibodies in breast cancer.

Background: The variability in responses to neoadjuvant treatment with anti-HER2 antibodies prompts to personalized clinical management and the development of innovative treatment strategies. Tumor-infiltrating Natural Killer (TI-NK) cells can predict the efficacy of HER2-targeted antibodies independently from clinicopathological factors in primary HER2-positive breast cancer patients. Understanding the mechanism/s underlying this association would contribute to optimizing patient stratification and provide the rationale for combinatorial approaches with immunotherapy.

Circadian Variation in Human Milk Hormones and Macronutrients.

There is an inadequate understanding of the daily variations in hormones and macronutrients in human milk (HM), and sample collection protocols vary considerably from study to study. To investigate changes in these milk components across 24 h, 22 lactating women collected small milk samples before and after each breastfeed or expression from each breast. Test weighing was used to determine the volume of HM consumed in each feed.
