Transgenerational associations between newborn metabolic profiles and bronchopulmonary dysplasia in neonates born to mothers with an obese phenotype.

Maternal obesity increases risk for bronchopulmonary dysplasia (BPD) by up to 42%. Identifying metabolic features that may contribute to the association between maternal pre-pregnancy body mass index (BMI) and BPD is critical in defining the molecular relationship between these conditions. We investigated the association between maternal obesity and BPD using newborn screen metabolites as an explanatory variable.

Immunohistochemical labeling of ongoing axonal degeneration 10 days following cervical contusion spinal cord injury in the rat.

Study Design: Experimental Animal Study.

Objective: To continue validating an antibody which targets an epitope of neurofilament light chain (NF-L) only available during neurodegeneration and to utilize the antibody to describe the pattern of axonal degeneration 10 days post-unilateral C4 contusion in the rat.

Setting: University of Florida laboratory in Gainesville, USA.

Assessing the impact of physical, mental and cognitive impairments on health-related quality of life in sepsis survivors following intensive care admission in New Zealand.

Aim: To assess the impact of physical, mental and cognitive impairments on health-related quality-of-life (QoL) of individuals who have survived sepsis after admission to an Intensive Care Unit (ICU) in New Zealand.

Methods: Survivors from a trial investigating vitamin C as an adjunctive therapy in patients with sepsis in Christchurch Hospital ICU were invited to enrol in a longitudinal QoL follow-up study. Patients were interviewed at hospital discharge, 30, 90 and 180 days, using validated physical and mental health assessment questionnaires (Short-Form-36, EuroQol-5-Dimension).

Neutralizing antibodies elicited in macaques recognize V3 residues on altered conformations of HIV-1 Env trimer.

Eliciting broadly neutralizing antibodies that protect against diverse HIV-1 strains is a primary goal of AIDS vaccine research. We characterized Ab1456 and Ab1271, two heterologously-neutralizing antibodies elicited in non-human primates by priming with an engineered V3-targeting SOSIP Env immunogen and boosting with increasingly native-like SOSIP Envs derived from different strain backgrounds. Structures of Env trimers in complex with these antibodies revealed V3 targeting, but on conformational states of Env distinct from the typical closed, prefusion trimeric SOSIP structure.
