The Unique Antimicrobial Recognition and Signaling Pathways in Tardigrades with a Comparison Across Ecdysozoa.

Tardigrades are microscopic animals known to withstand unfavorable abiotic conditions. These animals are also constantly exposed to biotic stresses, including parasites and internal microbiomes. However, the tardigrade immune mechanisms against these biotic stresses are largely uncharacterized.

Comparative myoanatomy of Tardigrada: new insights from the heterotardigrades Actinarctus doryphorus (Tanarctidae) and Echiniscoides sigismundi (Echiniscoididae).

Background: Tardigrada is a group of microscopic invertebrates distributed worldwide in permanent and temporal aquatic habitats. Famous for their extreme stress tolerance, tardigrades are also of interest due to their close relationship with Arthropoda and Cycloneuralia. Despite recent efforts in analyzing the musculature of a number of tardigrade species, data on the class Heterotardigrada remain scarce.

The journey of recovery and empowerment embraced by nature - clients' perspectives on nature-based rehabilitation in relation to the role of the natural environment.

This paper presents findings from real life situations, a longitudinal single case study on the role of natural environments in nature-based rehabilitation (NBR) for individuals with stress-related mental disorders, at the Alnarp Rehabilitation Garden in Sweden. A sample of 43 former clients voluntarily participated in semi-structured interview, and the data were analyzed according to interpretative phenomenological analysis (IPA). Three main superordinate themes were identified as the three phases of NBR-Prelude, Recuperating and Empowerment-explaining and illuminating the role of the natural environments in each phase.

Brain anatomy of the marine tardigrade Actinarctus doryphorus (Arthrotardigrada).

Knowledge of tardigrade brain structure is important for resolving the phylogenetic relationships of Tardigrada. Here, we present new insight into the morphology of the brain in a marine arthrotardigrade, Actinarctus doryphorus, based on transmission electron microscopy, supported by scanning electron microscopy, conventional light microscopy as well as confocal laser scanning microscopy. Arthrotardigrades contain a large number of plesiomorphic characters and likely represent ancestral tardigrades.

Changes in experienced value of everyday occupations after nature-based vocational rehabilitation.

Objective: The aim of this study was to describe and assess changes in participants' experiences of everyday occupations after nature-based vocational rehabilitation (NBVR), to assess changes regarding symptoms of severe stress and the rate of return to work and possible association with experiencing the occupational value of everyday occupations.

Methods: The NBVR was carried out by a transdisciplinary rehabilitation team and took place in a specially designed rehabilitation garden. The study had a longitudinal and mixed-method approach.

Neuroanatomy of Halobiotus crispae (Eutardigrada: Hypsibiidae): Tardigrade brain structure supports the clade Panarthropoda.

The position of Tardigrada in the animal tree of life is a subject that has received much attention, but still remains controversial. Whereas some think tardigrades should be categorized as cycloneuralians, most authors argue in favor of a phylogenetic position within Panarthropoda as a sister group to Arthropoda or Arthropoda + Onychophora. Thus far, neither molecular nor morphological investigations have provided conclusive results as to the tardigrade sister group relationships.

Muslim Middle Eastern clients' reflections on their relationship with their occupational therapists in mental health care.

Persons with a Middle Eastern background represent a minority in Sweden which has significantly increased in size over recent years. The purpose of the present study was to explore the elements that shape the experiences and perceptions of clients with a Middle Eastern background living by Muslim norms who received occupational therapy in mental health care at the time of participating in the study. The study included interviews with 11 clients who received occupational therapy in mental health care.

An occupational therapy approach to the support of a young immigrant female's mental health: A story of bicultural personal growth.

Young immigrants who suffer from psychosis perceive their illness from the outlook of at least two cultures, which is often a source of confusion and misunderstanding for clients, their families, and clinicians. This article presents a case study with a narrative approach, aiming to illustrate how an occupational therapy intervention can highlight the role of culture and address bicultural identification in a young adult immigrant woman with mental health problems. The results show how a culturally adapted intervention model can be used to help the client go through a transition from an interdependent to a more independent self.

Defying aches and revaluating daily doing: occupational perspectives on adjusting to chronic pain.

The aim of this study was to investigate how people with chronic pain experience their daily doing, with a special focus on possible adjustment to pain and altered life conditions in order to cope with pain and maintain well-being. In-depth interviews were guided by themes concerning daily occupation, ways to maintain well-being, and future expectations. Using qualitative content analysis a core concept "Reappraising daily doing" was arrived at, containing the categories of altering doing processes and altering values, each in turn containing four subcategories.

Occupational value and relationships to meaning and health: elaborations of the ValMO-model.

This study investigates the theoretical assumption of the Value and Meaning in Occupations model. The aim was to explore the relationship between occupational value, perceived meaning, and subjective health in a sample of individuals of working age, 50 men and 250 women. Frequency of experienced values in occupations was assessed through the Occupational Value instrument with pre-defined items.

Occupational therapists' experience of working with immigrant clients in mental health care.

Sweden's cultural diversity generates considerable challenges for occupational therapists. The aim of this study was to explore experiences and perceptions of occupational therapists working with immigrant psychiatric clients from the Middle East region. The study included interviews with eight occupational therapists employed in mental health care and working in a variety of settings.

Evaluation of evidence within occupational therapy in stroke rehabilitation.

Unlabelled: Evidence-based practice creates practice that integrates research-driven evidence with clinical expertise and patients' preferences in clinical decision-making.

Aim: The aim of this study was to investigate and evaluate the quality and applicability of scientific research in occupational therapy intervention related to the use of everyday life occupations and client-centred practice within stroke rehabilitation.

Design: Systematic searches of research studies published in English during 2000-2007 in peer-reviewed journals were undertaken.

Cyclomorphosis in Tardigrada: adaptation to environmental constraints.

Tardigrades exhibit a remarkable resilience against environmental extremes. In the present study, we investigate mechanisms of survival and physiological adaptations associated with sub-zero temperatures and severe osmotic stress in two commonly found cyclomorphic stages of the marine eutardigrade Halobiotus crispae. Our results show that only animals in the so-called pseudosimplex 1 stage are freeze tolerant.

Myoanatomy of the marine tardigrade Halobiotus crispae (Eutardigrada: Hypsibiidae).

The muscular architecture of Halobiotus crispae (Eutardigrada: Hypsibiidae) was examined by means of fluorescent-coupled phalloidin in combination with confocal laser scanning microscopy and computer-aided three-dimensional reconstruction, in addition to light microscopy (Nomarski), scanning electron microscopy, and transmission electron microscopy (TEM). The somatic musculature of H. crispae is composed of structurally independent muscle fibers, which can be divided into a dorsal, ventral, dorsoventral, and a lateral musculature.

Rasch analysis of an instrument for measuring occupational value: Implications for theory and practice.

This study investigated psychometric properties of an instrument for assessing perceived occupational value, the 26-item OVal-pd. Data from 225 Swedish subjects with and without known mental illness were analysed regarding fit to the Rasch measurement model (partial credit model), differential item functioning (DIF), and functioning of the OVal-pd four-category response scale. The reliability (index of person separation, analogous to Cronbach's alpha) was good (0.

Occupational value among individuals with long-term mental illness.

Purpose: The study compared the perceived value of occupation among a sample of individuals with long-term mental illness to a sample of people not diagnosed with mental illness. As well, it investigated whether diagnostic and demographic factors were related to perceived occupational value among the individuals with mental illness. Finally, the study examined the relationship between occupational value and ratings of health and well-being.
