The male voice: an evolutionary perspective

open access: yes
The introduction to this thesis outlines the evolutionary theory of human mating behaviour and describes the process of vocal production and auditory perception in humans. In addition it provides a brief overview of some of the research studies examining

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

open access: yesFEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Fundamental Frequency Characteristics of Adolescent Females

open access: yes, 1970
The purpose of the present study was to obtain data descriptive of the vocal pitch characteristics of adolescent females. The speaking voices of females at ages 11, 13 and 15 years were recorded and measured using standard phonellescopic procedures ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Measurement of Bridge Fundamental Frequency by Resistance Strain Gauges

open access: yes, 2010
Normally, the structural fundamental frequency can be got from the vibration tests by means of accelerometers or velocimeters linked with the dynamic signal measuring and analysis system.

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.
