Effects of Nature-Based Intervention in Occupational Health Care on Stress - A Finnish Pilot Study Comparing Stress Evaluation Methods.

Purpose: To assess methodology and its limitations for measuring effects of nature-based intervention (NBI).

Patients And Methods: Participants were 11 middle-aged female health care workers with lowered capacity to work. NBI included six group appointments in six months study period.

The effects of viewing a winter forest landscape with the ground and trees covered in snow on the psychological relaxation of young Finnish adults: A pilot study.

Forest bathing is an outdoor activity, and it might be a promising preventive treatment for social problems involving stress. A vast number of studies confirm the positive effects of this activity on people's health. Nevertheless, little is known about the influence of winter forest bathing when conducted in an environment with snow cover on the ground and trees.

Phenolic acid composition, antiatherogenic and anticancer potential of honeys derived from various regions in Greece.

The phenolic acid profile of honey depends greatly on its botanical and geographical origin. In this study, we carried out a quantitative analysis of phenolic acids in the ethyl acetate extract of 12 honeys collected from various regions in Greece. Our findings indicate that protocatechuic acid, p-hydroxybenzoic acid, vanillic acid, caffeic acid and p-coumaric acid are the major phenolic acids of the honeys examined.

Neutron activation-based gamma scintigraphy in pharmacoscintigraphic evaluation of an Egalet constant-release drug delivery system.

This paper is a report from a pharmacoscintigraphic study with an Egalet constant-release system containing caffeine and natural abundance samarium oxide. First the formulation was tested in vitro to clarify integrity during irradiation in the nuclear reactor. Then six healthy male volunteers were enrolled into the in vivo study.

Gamma scintigraphic evaluation of the fate of hydroxypropyl methylcellulose capsules in the human gastrointestinal tract.

The fate (movement and disintegration) of hard novel hydroxypropyl methylcellulose (HPMC) two-piece capsules in the human gastrointestinal tract was investigated using a gamma scintigraphic imaging method. Two different prolonged-release formulations without an active ingredient were used. The capsules contained different viscosity grades of HPMC powder (HPMC K100 and HPMC K4M).

Gamma scintigraphic evaluation of the fate of microcrystalline chitosan granules in human stomach.

In several reports of in vitro studies it has been suggested that the mucoadhesive chitosans could be of value in preparing gastro-retentive formulations. The aim of this study was to obtain direct in vivo evidence of whether microcrystalline chitosan (MCCh) formulations acted as gastro-retentive systems in humans. Neutron-activation-based gamma scintigraphy was used to study gastric residence times of MCCh granules in healthy male volunteers.
