Preparation, articulation, and photogrammetry of a neonatal moose skeleton.

Objective: Neonatal skeletal articulations for research and display purposes are uncommon due to issues surrounding incomplete bone maturation and reduced structural integrity that affect the bone preparation and articulation procedures. The present project was designed to add to the veterinary literature on neonatal moose osteological specimens, document the procedures of preparing and articulating a delicate specimen, and construct a 3-dimensional (3D) scan of the articulated skeleton that could be used for scientific and veterinary research and study worldwide.

Animal: A neonatal moose that had succumbed to capture myopathy resulting from entanglement in a barbed wire fence was the sole subject of this project.

Prevalence of obesity and cardiovascular disease in adults with type 2 diabetes and use of diabetes medication in Germany: A claims data study.

Aims: To identify the prevalence of cardiovascular disease (CVD) and obesity in patients with type 2 diabetes (T2D) in Germany and to evaluate if antidiabetic treatment patterns varied by comorbidity status.

Materials And Methods: Patients with T2D (aged ≥18 years) were identified during the study period (2014-2020) from medical claims of 4.5 million publicly insured German residents and divided into different cohorts based on CVD and/or obesity diagnosis.

Evaluation of Adherence and Persistence to Triple Therapy in Patients with COPD: A German Claims Data Study.

Purpose: Triple therapy (long-acting muscarinic antagonist/long-acting β-agonist/inhaled corticosteroid) is recommended for patients with chronic obstructive pulmonary disease (COPD) who experience recurrent exacerbations. Multiple-inhaler triple therapy (MITT) is associated with poor adherence and persistence. This study assessed comparative adherence and persistence to single-inhaler triple therapy (SITT) versus MITT among patients with COPD in a real-world setting in Germany.

Recruitment of epitope-specific T cell clones with a low-avidity threshold supports efficacy against mutational escape upon re-infection.

Repetitive pathogen exposure leads to the dominant outgrowth of T cell clones with high T cell receptor (TCR) affinity to the relevant pathogen-associated antigens. However, low-affinity clones are also known to expand and form immunological memory. While these low-affinity clones contribute less immunity to the original pathogen, their role in protection against pathogens harboring immune escape mutations remains unclear.

Acoustically Induced Vocal Training for Individuals With Impaired Hearing.

Objectives/hypothesis: Articulation, phonation, and resonance disorders in the speech of hearing-impaired-speakers reduces intelligibility. The study focusses on (1) whether nonacoustic feedback may facilitate the adjustment of the vocal tract, leading to increased vocal tract resonance, and (2) whether training with the feedback would be helpful for the subsequent formation of vowels.

Study Design: Prospective.

Adjustment of Vocal Tract Shape via Biofeedback: Influence on Vowels.

The study assessed 30 nonprofessional singers to evaluate the effects of vocal tract shape adjustment via increased resonance toward an externally applied sinusoidal frequency of 900 Hz without phonation. The amplification of the sound wave was used as biofeedback signal and the intensity and the formant position of the basic vowels /a/, /e/, /i/, /o/, and /u/ were compared before and after a vocal tract adjustment period. After the adjustment period, the intensities for all vowels increased and the measured changes correlated with the participants' self-perception.

Telechelic, Antimicrobial Hydrophilic Polycations with Two Modes of Action.

Telechelic antimicrobial poly(2-oxazoline)s with quaternary ammonium (quat) end groups are shown to be potent antimicrobial polymers against Gram-positive bacterial strains. In this study, the activity against the Gram-negative bacterium Escherichia coli is additionally implemented by hydrolyzing the poly(2-methyl-2-oxazoline) with two quart end groups to poly(ethylene imine) (PEI). The resulting telechelic polycations are active against Staphylococcus aureus and E.

Production, deformation and mechanical investigation of magnetic alginate capsules.

In this article we investigated the deformation of alginate capsules in magnetic fields. The sensitivity to magnetic forces was realised by encapsulating an oil in water emulsion, where the oil droplets contained dispersed magnetic nanoparticles. We solved calcium ions in the aqueous emulsion phase, which act as crosslinking compounds for forming thin layers of alginate membranes.

Poly(2-oxazoline)-Antibiotic Conjugates with Penicillins.

The conjugation of antibiotics with polymers is rarely done, but it might be a promising alternative to low-molecular-weight derivatization. The two penicillins penicillin G (PenG) and penicillin V (PenV) were attached to the end groups of different water-soluble poly(2-oxazoline)s (POx) via their carboxylic acid function. This ester group was shown to be more stable against hydrolysis than the β-lactam ring of the penicillins.
