| Abstract: | Functional homogenisation occurs across many areas and organism groups, thereby seriously affecting biodiversity loss and ecosystem functioning. In this study, we examined how functional features of aquatic macrophytes have changed during a 70-year period at community and species levels in a boreal lake district. At the community level, we examined if aquatic macrophyte communities showed different spatial patterns in functional composition and functional richness in relation to main environmental drivers between the time periods. We also observed each species in functional space to assess if species with certain sets of traits have become more common or rare in the 70-year study period. We found changes in the relationship between functional community composition and the environment. The aquatic macrophyte communities showed different patterns in functional composition between the two time periods, and the main environmental drivers for these changes were partly different. Temporal changes in functional richness were only partially linked to concomitant changes in the environment, while stable factors were more important. Species’ functional traits were not associated with commonness or rarity patterns. Our findings revealed that functional homogenisation has not occurred across these boreal lakes, ranging from small oligotrophic forest lakes to larger lakes affected by human impacts. |

(BioMed Central, 2019)Abstract Background The Critical Assessment of Functional Annotation (CAFA) is an ongoing, global, community-driven effort to evaluate and improve the computational annotation of protein function. Results Here, we report on the results of the third CAFA challenge, CAFA3, that featured an expanded analysis over the previous CAFA rounds, both in terms of volume of data analyzed and the types of analysis performed. In a novel and major new development, computational predictions and assessment goals drove some of the experimental assays, resulting in new functional annotations for more than 1000 genes. Specifically, we performed experimental whole-genome mutation screening in Candida albicans and Pseudomonas aureginosa genomes, which provided us with genome-wide experimental data for genes associated with biofilm formation and motility. We further performed targeted assays on selected genes in Drosophila melanogaster, which we suspected of being involved in long-term memory. Conclusion We conclude that while predictions of the molecular function and biological process annotations have slightly improved over time, those of the cellular component have not. Term-centric prediction of experimental annotations remains equally challenging; although the performance of the top methods is significantly better than the expectations set by baseline methods in C. albicans and D. melanogaster, it leaves considerable room and need for improvement. Finally, we report that the CAFA community now involves a broad range of participants with expertise in bioinformatics, biological experimentation, biocuration, and bio-ontologies, working together to improve functional annotation, computational function prediction, and our ability to manage big data in the era of large experimental screens.

(BioMed Central, 2020)Abstract Background Skeletal dysplasias are rare disorders often leading to severe short stature. This study aimed to gain new comprehensive information about functioning and equality in people affected by skeletal dysplasia compared to matched controls without skeletal dysplasia. Methods Functioning was assessed by questionnaire, which was formed by operationalizing International Classification of Functioning, Disability and Health (ICF) core set’s categories into the items according to the ICF linking rules, using primarily Patient Reported Outcomes Measurement Information System PROMIS® - items. Results Altogether 80 subjects with skeletal dysplasia and 55 age-, gender- and place of residence -matched controls participated. People with skeletal dysplasia experienced more pain (p < 0.001) and the pain interfered more their daily lives (p = 0.037) compared to the controls. They had more problems related to musculoskeletal functions and exercise tolerance, difficulties in mobility, used more assistive products and technology and were more affected by climate and seasonal changes (p < 0.001). They met challenges in self-care, acquisition of goods and services and household tasks (p < 0.001) and in participating in close social relationships, leisure time activities (p < 0.001) and associations and organizational services (p = 0.007). They felt less satisfied with remunerative work (p = 0.003), felt more inequality (p = 0.008), met more negative attitudes of others (p < 0.001) and felt having less support given by family and friends (p = 0.022). They used more social and health services and experienced more dissatisfaction with those. Conclusions Our study indicates that skeletal dysplasias restrict functioning extensively and significantly affect daily living. By building accessible environment and improving equal services, functioning could be improved.

(2019)Background and purposeImpairment of executive functions (EFs) is a common cognitive symptom post-stroke and affects independence in daily activities. Previous studies have often relied on brief cognitive tests not fully considering the wide spectrum of EF subdomains. A detailed assessment of EFs was used to examine which of the subdomains and tests have the strongest predictive value on post-stroke functional outcome and institutionalization in long-term follow-up. MethodsA subsample of 62 patients from the Helsinki Stroke Aging Memory Study was evaluated with a battery of seven neuropsychological EF tests 3 months post-stroke and compared to 39 healthy control subjects. Functional impairment was evaluated with the modified Rankin Scale (mRS) and Instrumental Activities of Daily Living (IADL) scale at 3 months, and with the mRS at 15 months post-stroke. Institutionalization was reviewed from the national registers of permanent hospital admissions in up to 21-year follow-up. ResultsThe stroke group performed more poorly than the control group in multiple EF tests. Tests of inhibition, set shifting, initiation, strategy formation and processing speed were associated with the mRS and IADL scale in stroke patients. EF subdomain scores of inhibition, set shifting and processing speed were associated with functional outcome. In addition, inhibition was associated with the risk for earlier institutionalization. ConclusionsExecutive function was strongly associated with post-stroke functional impairment. In follow-up, poor inhibition was related to earlier permanent institutionalization. The results suggest the prognostic value of EF subdomains after stroke.
