Physik der höchsten Töne: Piccolo und Rekord‐Pfiffe

open access: yesPhysik in unserer Zeit, Volume 56, Issue 3, Page 138-139, May 2025.
Nicht nur bei Instrumenten, auch mit dem Mund, beim Singen und Pfeifen, wird nach höchsten Tönen gestrebt. Zusammenfassung Höchste Töne im Bereich von c5 mit über 4 kHz Schwingungsfrequenz erreicht die Piccolo‐Flöte. Auch Orgeln, Pianos, Glockenspiele und Xylophone schaffen das c5.

Sex and Morph Variation in Activity From Early Ontogeny to Maturity in Ruffs (Calidris pugnax)

open access: yesEthology, Volume 131, Issue 3, March 2025.
We measured the activity (distance travelled in an open‐field test) in young ruffs multiple times throughout their first two years of life. Besides the two sexes, ruffs feature three mating morphs (independents, satellites and faeders). After chicks had lost their crouching reflex—a common threat response—activity rapidly increased. Activity stabilised

The Effect of a Three‐Month Aquatic Training Program on Physical Functioning in Elderly Men: A Randomized Controlled Trial

open access: yesInternational Journal of Clinical Practice, Volume 2025, Issue 1, 2025.
Background: Aquatic training is emerging as a multifaceted therapy for enhancing health parameters, particularly among elderly populations. This study aimed to investigate the effects of a three‐month aquatic training on physical functioning, including balance, muscular strength, and flexibility, among healthy older men. Methods: From an initial sample

Neurofilament Light Chain Is Associated With Acute Mountain Sickness

open access: yesBrain and Behavior, Volume 14, Issue 11, November 2024.
Healthy subjects were exposed to simulated high altitude (4500 m) two times, i.e., within Cycle 1 and Cycle 2, the latter with a random assignment to prior acclimatization or sham acclimatization. Before and after each cycle, pNfL was measured. pNfL levels increased over the total study period.

The activity of the quorum sensing regulator HapR is modulated by the bacterial extracellular vesicle (BEV)‐associated protein ObfA of Vibrio cholerae

open access: yesJournal of Extracellular Vesicles, Volume 13, Issue 9, September 2024.
Bacterial extracellular vesicles (BEVs) released by the facultative human pathogen Vibrio cholerae during biofilm formation act as an intra‐species communication tool. The BEV‐associated protein ObfA modulates activity of the central cytoplasmic transcriptional regulator HapR and thereby affects biofilm formation as well as virulence, which represent ...

Comparative Analysis of PEG‐Free and PEG‐Based Self‐Emulsifying Drug Delivery Systems for Enhanced Oral Bioavailability of Therapeutic (Poly) Peptides

open access: yesSmall, Volume 20, Issue 27, July 4, 2024.
This study presents a novel strategy to boost oral bioavailability of insulin glargine (IG) using polyglycerol/zwitterion‐based self‐emulsifying drug delivery systems (PG/ZW‐SEDDS) as an alternative to polyethylene glycol‐based SEDDS (PEG‐SEDDS). Research focuses on optimizing hydrophobic ion pairing (HIP) complexation, developing a PEG‐free SEDDS, and

Suitability of Fourier transform infrared microscopy for the diagnosis of cystic echinococcosis in human tissue sections

open access: yesJournal of Biophotonics, Volume 17, Issue 6, June 2024.
Cystic echinococcosis (CE) is a global health concern caused by cestodes. In this retrospective case study, Fourier transform infrared microscopy was explored for detecting and identifying CE through biochemical changes in human tissue sections. Results revealed the method's ability to distinguish echinococcus elements from human tissue, irrespective ...
