Isolation and characterisation of a heparosan capsular polysaccharide and a core oligosaccharide from Moraxella lincolnii strain CCUG 52988.

Moraxella lincolnii is a Gram-negative bacterium that resides in the upper respiratory tract (URT) of humans and may have a role as a member of a protective microbial community. Structural characterisation studies of its outer membrane glycan structures are very limited. We report here the isolation and structural characterisation (NMR, GLC-MS) of a capsular polysaccharide (CPS) and an oligosaccharide (OS) (lipooligosaccharide (LOS)-derived) isolated from strain CCUG 52988.

Machine Learning to Detect Cervical Spine Fractures Missed by Radiologists on CT: Analysis Using Seven Award-Winning Models from the RSNA 2022 Cervical Spine Fracture AI Challenge.

Available data on radiologists' missed cervical spine fractures are based primarily on studies using human reviewers to identify errors on re-evaluation; such studies do not capture the full extent of missed fractures. To use machine-learning (ML) models to identify cervical spine fractures on CT missed by interpreting radiologists, characterize the nature of these fractures, and assess their clinical significance. This retrospective study included all cervical spine CT examinations performed in adult patients in the emergency department between January 1, 2018 and December 31, 2022.

Chain Transfer Kinetics of Rhodixan A1 RAFT/MADIX Agent.

Rhodixan A1 is the trade name for -ethyl -(1-methoxycarbonylethyl)dithiocarbonate, a RAFT/MADIX agent used by Syensqo to produce block copolymer additives for aqueous formulations on an industrial scale. Chain transfer coefficients to Rhodixan A1 determined for 25 different styrenic, acrylate, and acrylamide monomers were relatively low (0.6 < C < 3.

Discrimination, Violence, Mental Health, and Substance Use by Age and Cancer History Among LGBTQ+ Individuals.

Young adult (YA) LGBTQ+ cancer survivors face inequities and unmet needs that impact their well-being. However, the impact of age and cancer among LGBTQ+ individuals have not been adequately assessed. The North Carolina LGBTQ+ Health Needs Assessment survey, conducted at local Pride events, aimed to collect data to describe the well-being of LGBTQ+ people in NC.

Comparing peer relationship ratings among adolescents with sport and non-sport related concussions.

Objective: To evaluate if peer relationship ratings differ among adolescents who sustain a sport-related concussion compared to those who sustain a non-sport-related concussion.

Study Design: We conducted a cross-sectional investigation of 123 adolescents who sustained a concussion within 21 days before their initial post-injury evaluation (mean = 9.2 ± 3.
