Most research on compassion utilizes self-report measures. Subjective report of the individual can provide an authentic window about compassion toward the self. Compassionate behavior toward another person, on the other hand, can and should be measured more objectively than self-report allows. Compassionate behavior toward another can best be measured by how that individual actually interacts with others. In this essay, we will describe how behavior that is compassionate can be objectively measured, and one that ha [...]

Microbes have been part of the diet throughout human history. In the evolution of food preservation practices, some techniques inadvertently leveraged microbial activity not only to extend the storage life but also to enhance the properties and nutritive value of foods. In the last century, a variety of bacterial species (referred to as probiotics) were found to confer health benefits to the host. The advent of high-throughput sequencing methods facilitated improved surveillance of conventional probiotics within gu [...]

We investigated whether healthy older adults who live in female-dominated old age care homes can identify the gender of male and female faces of people from different ethnicities in the same way as young adults. We hypothesized that this mainly female environment would lead by exposure to a female-gender bias. A sample of 40 participants aged 20-30 and 70-80 years identified the sex-of-face of 120 images of young and old adults, male and female faces, black and white faces, presented in a randomized sequence in a s [...]

The ketogenic diet (KD) is currently well known in the lay media as a quick way to lose weight. However, the KD is not a new medical concept. The KD was used in the early 1900s to control seizures. However, as we developed more effective pharmacological agents, we used the KD less until it became practically obscure by the 1980s. Similar to the effects of fasting, the KD leads to the production of ketones as an alternative energy source to glucose. Therefore, the KD has many beneficial metabolic effects, such as an [...]

To increase the amount of information on the intensities of tropical cyclones (TC) used in climate research, the possibility of additional estimates of the intensity of a TC by exploring historical data of conventional (non-Doppler) airborne and coastal radars is considered. Based on the hyperbolic-logarithmic spiral (HLS) model of the streamline in the TC, an assessment of the maximum wind speed in hurricanes Cleo (1958), Carolina (1975) and Alicia (1983) was made. Literature sources containing radar signatures of [...]

Aneurysmal subarachnoid hemorrhage (aSAH) causes serious brain injury, and its mechanisms have not been completely unraveled so far. The causative factors for the brain injury initiated by an aneurysm rupture, which is referred to as the early brain injury (EBI), include elevated intracranial pressure, cerebral hypoperfusion, and blood contents that are directly exposed to the brain surface. At Day 4–14 post aSAH, delayed cerebral ischemia (DCI) often develops, which may worsen the neurological outcomes critically. [...]

Feasibility studies play a critical role in determining whether the target population is likely to engage with larger scale efficacy and effectiveness trials. Feasibility data for yoga interventions designed and conducted with older adults is limited. In this paper we present feasibility and acceptability data from an 8-week randomized controlled trial (RCT) conducted with middle aged and older adults. Participants n=118 (Mean age: 62.0 years) were randomized to either a Hatha yoga or Stretching Control group with [...]

Myokines are cytokines secreted from muscle during contraction and are implicated in autocrine, paracrine, and endocrine regulation of biological systems. It is postulated that myokines contribute to skeletal muscle adaptations in response to resistance exercise. Exercise, including resistance exercise, is an important factor in the management of maintaining skeletal muscle strength, mass, and function with aging. Sarcopenia is exacerbated with increased age and therefore, it is important to understand the potentia [...]

Genito-Pelvic Pain Penetration Disorder (GPPPD) affects between eight and twenty percent of women. There is recent evidence that compassion focused therapy (CFT) can help those with general health conditions and persistent pain. This study aims to investigate application of CFT techniques to an existing psychosexual therapy group of women with GPPPD and establish an effect size that could be used in a fully powered trial in future. The study took place within a routine clinical setting. Women who attended a group w [...]
