The Careful Project: Evaluating the acceptability of local virtual reality experiences as a leisure activity for residents in aged care.

Objectives: The aim of this project was to evaluate the feasibility and acceptability of virtual reality (VR) as a leisure activity for people living in residential aged care. Virtual reality experiences may offer alternatives for residents with limited mobility, or during times when older people are unable to leave residential care.

Methods: The intervention used VR videos delivered via a head-mounted device.

Positive psychological well-being: A novel concept for improving symptoms, quality of life, and health behaviors in irritable bowel syndrome.

Background: Though a growing body of research suggests that greater positive psychological well-being in irritable bowel syndrome (IBS) may be protective, existing brain-gut behavior therapies primarily target negative psychological factors. Little is known about how positive psychological factors in IBS relate to IBS symptoms, health-related quality of life (HRQoL), or adherence to key health behaviors, such as physical activity and diet modification. Accordingly, per the ORBIT model of behavioral treatment development for chronic diseases, we explored potential connections between psychological constructs and IBS symptoms, health behavior engagement (physical activity and dietary modification), and HRQoL in a qualitative study to inform the development of a novel brain-gut behavior therapy.

Phenylpropanoid glucosides from leaves of Coussarea hydrangeifolia (Rubiaceae).

Phenylpropanoid glycosides, 1'-O-benzyl-alpha-L-rhamnopyranosyl-(1''-->6')-beta-D-glucopyranoside (1) and alpha-L-xylopyranosyl-(4''-->2')-(3-O-beta-D-glucopyranosyl)-1'-O-E-caffeoyl-beta-D-glucopyranoside (2), together with the known derivatives, 1,6-di-O-caffeoyl-beta-D-glucopyranoside (3), 1-O-(E)-caffeoyl-beta-D-glucopyranoside (4) and 1-O-(E)-feruloyl-beta-D-glucopyranoside (5), were isolated from leaves of Coussarea hydrangeifolia. Their structures were determined by IR, HRESIMS, and 1D and 2D NMR experiments, and their antioxidant activities, evaluated by assaying the free radical scavenging capacity using the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical as substrate. The antioxidant activities of 3 and 4 (IC50 values of 15.

[Experiences with the use of oscillating high frequency ventilation].

Our investigations have demonstrated that the effect of oscillatory high-frequency ventilation (HFO) on gas exchange in dogs is directly proportional to the oscillatory flow amplitude VM. Because of the equation: VM = PM/Z, gas exchange is increasing with rising oscillatory amplitude of the ventilation pressure PM and decreasing with rising impedance Z of the respiratory system. This system consists of endotracheal tube and the lungs of the dog investigated.

[Equipment combination for the use of normal frequency and high frequency jet ventilation].

Over the last eight years high-frequency ventilation has been extensively evaluated both in the clinical and laboratory settings. Two types of jet ventilators for application of normofrequency and high-frequency jet ventilation have been developed. A combined equipment is described with gas mixer, heater-humidifier, monitoring, membrane solenoid valve and a special injection system.
