Down SyndromeDown syndrome, also known as Trisomy 21, is one of the most common chromosome abnormalities in humans. It occurs when a child's cells end up with 47 chromosomes instead of the usual 46. Down syndrome causes intellectual disability and other physical and learning challenges.

AnaphylaxisAnaphylaxis is rapid onset severe allergic reaction to an allergen. These allergens are most commonly food, insects, or medication. Anaphylactic reactions are serious and can be life-threatening.

Anti-metabolite chemotherapy increases LAG-3 expressing tumor-infiltrating lymphocytes which can be targeted by combination immune checkpoint blockadeAntibodies that target immune checkpoints such as cytotoxic T lymphocyte antigen 4, programmed cell death protein/ligand 1 are approved for treatment of multiple cancer types.

Antecedent and persistent symptoms in COVID-19 and other respiratory illnesses: Insights from prospectively collected data in the BRACE trialSome individuals have a persistence of symptoms following both COVID-19 (post-acute COVID-19 syndrome; PACS) and other viral infections. This study used prospectively collected data from an international trial to compare symptoms following COVID-19 and non-COVID-19 respiratory illness, to identify factors associated with the risk of PACS, and to explore symptom patterns before and after COVID-19 and non-COVID-19 respiratory illnesses.

DNA Methylation signatures underpinning blood neutrophil to lymphocyte ratio during first week of human lifeUnderstanding of newborn immune ontogeny in the first week of life will enable age-appropriate strategies for safeguarding vulnerable newborns against infectious diseases. Here we conducted an observational study exploring the immunological profile of infants longitudinally throughout their first week of life.

Hyperactive Nickase Activity Improves Adenine Base EditingBase editing technologies enable programmable single-nucleotide changes in target DNA without double-stranded DNA breaks. Adenine base editors (ABEs) allow precise conversion of adenine to guanine. However, limited availability of optimized deaminases as well as their variable efficiencies across different target sequences can limit the ability of ABEs to achieve effective adenine editing.

A pilot randomised controlled trial of a telehealth-delivered brief ‘Sleeping Sound Autism’ intervention for autistic childrenAccess to behavioural sleep intervention is beneficial for autistic children, yet many families face barriers to access associated with location and time. Preliminary evidence supports telehealth-delivered sleep intervention. However, no studies have evaluated brief telehealth sleep intervention.

Understanding variations in the built environment over time to inform longitudinal studies of young children's physical activity behaviour - The BEACHES projectWe know relatively little about the role the neighbourhood built environment plays in promoting young children's physical activity, particularly its longitudinal effect either through repeated exposure to the same environment or through change in exposure by moving from one neighbourhood to another.

Patient-derived xenografts and single-cell sequencing identifies three subtypes of tumor-reactive lymphocytes in uveal melanoma metastasesUveal melanoma is a rare melanoma originating in the eye's uvea, with 50% of patients experiencing metastasis predominantly in the liver. In contrast to cutaneous melanoma, there is only a limited effectiveness of combined immune checkpoint therapies, and half of patients with uveal melanoma metastases succumb to disease within 2 years.
