Daily rhythms of the sleep-wake cycle

Journal of Physiological Anthropology, 2012
The amount and timing of sleep and sleep architecture (sleep stages) are determined by several factors, important among which are the environment, circadian rhythms and time awake. Separating the roles played by these factors requires specific protocols,

Standard reference values of weight and maximum pressure distribution in healthy adults aged 18–65 years in Germany

Journal of Physiological Anthropology, 2020
Background The aim of this study was to collect standard reference values of the weight and the maximum pressure distribution in healthy adults aged 18–65 years and to investigate the influence of constitutional parameters on it.

Indication of a massive circumbinary planet orbiting the low-mass X-ray binary MXB 1658−298 [PDF]

, 2017
We present an X-ray timing analysis of the transient X-ray binary MXB 1658-298, using data obtained from the RXTE and XMM-Newton observatories. We have made 27 new mid eclipse time measurements from observations made during the two outbursts of the ...

Cathodal transcranial direct-current stimulation over right posterior parietal cortex enhances human temporal discrimination ability

Journal of Physiological Anthropology, 2017
Background Time perception associated with durations from 1 s to several minutes involves activity in the right posterior parietal cortex (rPPC). It is unclear whether altering the activity of the rPPC affects an individual’s timing performance. Here, we

Radiologic evaluation of orbital index among Ghanaians using CT scan

Journal of Physiological Anthropology, 2017
Background Orbital index (OI) expresses the proportion of the orbital height to the orbital width and varies with race, regions within the same race and periods in evolution. This index is useful in forensic medicine, anthropology and surgery.

Differences in sarcopenia indices in elderly Japanese women and their relationships with obesity classified according to waist circumference, BMI, and body fat percentage

Journal of Physiological Anthropology
Background Sarcopenic obesity (SO) is defined as a decrease in lean body mass and an increase in body fat mass (BFM) due to aging. Detecting SO in elderly women is important from the perspective of extending healthy life expectancy. While various indices

Human pupillary light reflex during successive irradiation with 1-ms blue- and green-pulsed light

Journal of Physiological Anthropology, 2017
Background In the human retina, the contribution of intrinsically photosensitive retinal ganglion cells (ipRGCs) to the regulation of the pupillary response remains poorly understood.

Cubic Perovskite Structure of Black Formamidinium Lead Iodide, α-[HC(NH2)2]PbI3, at 298 K

Journal of Physical Chemistry Letters, 2015
The structure of black formamidinium lead halide, α-[HC(NH2)2]PbI3, at 298 K has been refined from high resolution neutron powder diffraction data and found to adopt a cubic perovskite unit cell, a = 6.3620(8) Å.

Recent updates on cold adaptation in population and laboratory studies, including cross-adaptation with nonthermal factors

Journal of Physiological Anthropology
This review aims to update our understanding of human cold adaptation. First, an overview of the thermoregulatory response to cold is provided, with some recent updates in human brown adipose tissue (BAT).

Human dispersal into East Eurasia: ancient genome insights and the need for research on physiological adaptations

Journal of Physiological Anthropology
Humans have long pondered their genesis. The answer to the great question of where Homo sapiens come from has evolved in conjunction with biotechnologies that have allowed us to more brightly illuminate our distant past.
