- Background: It has been shown previously that an anterior cruciate ligament injury may affect postural control, measured by balance in single-limb stance. To our knowledge, no studies have reported the influence of measures of impairment on postural control after such an injury. Purpose: To assess the influence of knee laxity, proprioception, and muscle strength on balance in single-limb stance and to study the correlation between balance in single-limb stance and subjective estimation of extremity function. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 36 patients with a unilateral, nonoperated, nonacute anterior cruciate ligament injury were examined with regard to anterior knee laxity, proprioception, muscle strength, and stabilometry (amplitude and average speed of the center of pressure movements). Subjective estimation of extremity function was measured on a visual analog scale. Results: The multiple regression analysis showed that high knee laxity values were associated with high amplitude values and low average speed. Poor proprioception and high muscle strength values were associated with low average speed among the women only. Low amplitude values correlated with better subjective function. Conclusion: Anterior knee laxity, proprioception, and muscle strength seem to play a role in maintaining balance in single-limb stance. Patients with low amplitude values in stabilometry were those with better subjective function.

Comparison of the electron transport properties of the psbo1 and psbo2 mutants of Arabidopsis thaliana
- 2009

In: Biochimica et Biophysica Acta - Bioenergetics. - : Elsevier BV. - 0005-2728 .- 1879-2650. ; 1787:10, s. 1230-1237

Journal article (peer-reviewed)abstract
- Genome sequence of Arabidopsis thaliana (Arabidopsis) revealed two psbO genes (At5g66570 and At3g50820) which encode two distinct PsbO isoforms: PsbO1 and PsbO2, respectively. To get insights into the function of the PsbO1 and PsbO2 isoforms in Arabidopsis we have performed systematic and comprehensive investigations of the whole photosynthetic electron transfer chain in the T-DNA insertion mutant lines, psbO1 and psbo2. The absence of the PsbO1 isoform and presence of only the PsbO2 isoform in the psbo1 mutant results in (i) malfunction of both the donor and acceptor sides of Photosystem (PS) 11 and (ii) high sensitivity of PSII centers to photodamage, thus implying the importance of the PsbO1 isoform for proper structure and function of PSII. The presence of only the PsbO2 isoform in the PSII centers has consequences not only to the function of PSII but also to the PSI/PSII ratio in thylakoids. These results in modification of the whole electron transfer chain with higher rate of cyclic electron transfer around PSI, faster induction of NPQ and a larger size of the PQ-pool compared to WT, being in line with apparently increased chlororespiration in the psbo1 mutant plants. The presence of only the PsbO1 isoform in the psbo2 mutant did not induce any significant differences in the performance of PSII under standard growth conditions as compared to WT. Nevertheless, under high light illumination, it seems that the presence of also the PsbO2 isoform becomes favourable for efficient repair of the PSII complex.

Dose-response associations between musculoskeletal disorders and physical and psychosocial factors among construction workers
- 2005

In: Scandinavian Journal of Work, Environment and Health. - 0355-3140. ; 31:2, s. 57-67
-
Journal article (peer-reviewed)abstract
- Background As musculoskeletal disorders are common in general populations and they therefore constitute a heavy burden to society, the identification of their determinants is important. The aim of this study was to identify dose-response associations for location-specific prevalences of musculoskeletal disorders with various physical exposures and psychosocial factors in a large group of workers. Methods The study was based on cross-sectional data from self-administered questionnaires filled out by 85 191 male employees in the Swedish construction industry. In addition to symptoms from nine musculoskeletal locations, the questionnaire addresses physical exposures and psychosocial factors. Logistic regression methods were used to study disorder prevalence in relation to scales of these exposures and factors. Results Compared with working rarely in a stooping or twisted posture, the odds ratio (OR) for lower back disorder with respect to often working in this posture was 3.05 [95% confidence interval (95% CI) 2.73-3.42]. The OR values for work with hands above the shoulders and for neck and shoulder disorders were 2.93 (95% CI 2.65-3.24) and 3.66 (95% CI 3.32-4.04), respectively. Among the psychosocial factors, sleeping problems and hurrying without reason were associated with symptoms in all of the body locations, the highest OR being found for neck symptoms and sleeping problems, 2.44 (95% CI 2.15-2.78). Conclusions Work in awkward postures has strong location-specific dose-response associations. In contrast, some psychosocial factors, primarily those reflecting characteristics of individual persons, are strongly associated with symptoms in all body locations. Symptoms seem not to be associated with factors like support from workmates or supervisors or control of the work situation. All location-specific prevalence rates seem to increase strongly with age.

A population-based study of macular thickness in full-term children assessed with Stratus OCT: normative data and repeatability.
- 2009

In: Acta ophthalmologica. - : Wiley. - 1755-3768 .- 1755-375X. ; 87:7, s. 741-745

Journal article (peer-reviewed)abstract
- Purpose: We aimed to determine normal macular thickness values, assessed with optical coherence tomography (OCT), in a population of full-term children of normal birthweight. Methods: A total of 56 children, aged 5-16 years, randomly chosen from the population register, were examined with Stratus OCT. Only children with visual acuity < 0.2 logMAR, spherical equivalent of - 3 to + 3 D and astigmatism < 2 D were included. The fast macular map protocol was used and three examinations were performed in each eye. One eye was then randomized for further analyses. Mean values for the nine ETDRS areas, foveal minimum thickness and macular volume were calculated for 55 eyes. Coefficients of variance and intraclass correlations were calculated for each area. Results: All children co-operated well and no child was excluded for lack of concentration. Mean +/- standard deviation central macular thickness was 204 +/- 19 mum. Mean total macular volume was 7.11 +/- 0.35 mm(3). No correlations were found between age, gender and macular thickness. Coefficients of variance were < 2% and intraclass correlations were > 0.9 in all areas, except the foveal minimum. Conclusions: Normal values for macular thickness in healthy full-term children were reported. As the Stratus OCT provides normal values only for adults, these data are a better alternative for comparison with children with retinal abnormalities. We concluded that OCT is suitable for examining the retina in children aged 5-16 years and has the same high level of repeatability as in adults.

Morning warming-up exercise-effects on musculoskeletal fitness in construction workers.
- 2005
-
In: Applied Ergonomics. - : Elsevier BV. - 1872-9126 .- 0003-6870. ; 36:4, s. 513-519
-
Journal article (peer-reviewed)abstract
- The aim of the present study was to evaluate the effects on muscle stretchability, joint flexibility, muscle strength and endurance in construction workers of a 3-month period of a 10-min morning warming-up exercise (MWU), performed at the building site every working day. Thirty construction workers participated in the program. Seventeen construction workers at other building sites served as controls. Muscle stretchability, joint flexibility, muscle strength and endurance were measured before and after the program. Significant increase of thoracic and lower back mobility, increase of hamstring and thigh muscle stretchability were seen in the MWU group. A significant difference in back muscle endurance was found due to decreased endurance in the controls. Muscular strength was not influenced by the MWU. The results indicate that a short dose of morning warming-up exercise could be beneficial for increasing or maintaining joint and muscle flexibility and muscle endurance for workers exposed to manual material handling and strenous working positions.
