Forskningsöversikt (refereegranskat)abstract
- In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

- Dewar photoproduct (Dewar PP) is the valence isomer of (6-4) photoproduct ((6-4)PP) in photodamaged DNA. Compared to the extensive studied CPD photoproducts, the underlying repair mechanisms for the (6-4)PP, and especially for the Dewar PP, are not well-established to date. In this paper, the repair mechanism of DNA Dewar photoproduct T(dew)C in (6-4) photolyase was elucidated using hybrid density functional theory. Our results showed that, during the repair process, the T(dew)C has to isomerize to T(6-4)C photolesion first via direct C6'-N3' bond cleavage facilitated by electron injection. This isomerization mechanism is energetically much more efficient than other possible rearrangement pathways. The calculations provide a theoretical interpretation to recent experimental observations.

- Background. Caregiver engagement and collaborative team early childhood intervention (ECI) services are international trends; however, relevant evidence of collaborative home-visiting ECI in rural areas is as yet undetermined.Objective. The study aimed to investigate the effectiveness of a collaborative ECI program in a rural area of Taiwan.Design. The study was a pilot randomized control led trial.Methods. Children aged 6 to 33 months experiencing motor delays and their caregivers were enrolled in Taitung, Taiwan. Using stratified randomization, 24 participants were allocated to either experimental or control groups, and both received 5 home visits within 3 months. The experimental group received ECI services based on the International Classification of Functioning, Disability and Health framework and family-centered approaches. The control group received regular home visits by local social workers. Child outcomes included Pediatric Evaluation of Disability Inventory Chinese Version and Peabody Developmental Motor Scale, 2nd edition. Family outcomes included the Disability-Adapted Infant–Toddler version of Home Observation for Measurement, and Chinese versions of the Knowledge of Infant Development Inventory and Parental Stress Index-Short Form. A tester blinded to the study conducted assessments at baseline, postintervention, and 3-month follow-up. Two-way mixed analysis of variance was used with α = .05 (2-tailed).Results. The experimental group improved scores on the Disability-Adapted Infant–Toddler version of Home Observation for Measurement significantly more than the control group with an effect size of 0.64 at follow-up. In other outcomes, both groups showed no significant differences. The follow-up rate was 69%, and adherence to the ECI program was acceptable.Limitations. A limitation of the study was the heterogeneity of the sample.Conclusions. This pilot study revealed possible effectiveness in implementing collaborative ECI programs based on family-centered approaches and the International Classification of Functioning, Disability and Health in rural areas. Larger field studies are needed to confirm our findings.

Bokkapitel (refereegranskat)abstract
- Children and youth with special needs from age two to 18 years in Taiwan receive evaluation and services from both the Ministry of Health and Welfare and the Ministry of Education based on the People with Disabilities Rights Protection Act (Ministry of Health and Welfare, 2007) and the Special Education Act (Ministry of Education, 2014). On the basis of the earlier two acts, those children could apply for Disability Identification to receive related services, which are provided by the local social welfare department, and could also apply for special education services provided by the local educational department if they are going to attend preschool or higher-level school (both public and private). Special education placements range widely, from inclusion in regular classes in school to segregated setting in special education schools.

- Participation has significant impact on children’s health and well-being. Knowledge is limited on how children with disabilities perceive their participation and whether their perceptions differ from their parents. This pilot study aimed to explore whether self-reported frequency of participation and prioritized activities differ between children with disabilities and their parents. Thirty children with disabilities eligible for special education in elementary school and their parents were included. Each of them were interviewed with the Chinese version of Picture My Participation (PMP), separately, to identify the child’s participation frequency in 21 activities at home, school, and community, desire-to-change activities, and the level of involvement in these activities. The results indicated that children’s ratings of participation frequency were significantly lower than parents’ ratings in home activities but not in school and community activities, as analyzed by the Wilcoxon Signed Ranked test. Nineteen (63%) child–parent pairs had selected entirely different items as their desire-to-change activities. Children selected the activities that they were somewhat to very involved in; while parents selected the activities they thought their children were less involved in. Our findings suggest that children with disabilities had unique views on life and this should be supported in their health care and individualized education plans.

- Animal studies suggest that regulatory T (T(reg)) cells play a beneficial role in ventricular remodeling and our previous data have demonstrated defects of T(reg) cells in patients with chronic heart failure (CHF). However, the mechanisms behind T(reg-)cell defects remained unknown. We here sought to elucidate the mechanism of T(reg-)cell defects in CHF patients.

- The mitochondrial genome (mitogenome) can help us understand the phylogenetic relationships within the genus Lethe and the subfamily Satyrinae. In this study, we sequenced the complete mitogenomes of 14 Lethe species, which range in size from 15,225 to 15,271 bp, with both 37 genes (13 PCGs, 22 tRNAs, 2 rRNAs) and a noncoding A + T-rich region. The gene arrangement and orientation is similar to typical mitogenomes of Lepidoptera. The Ka/Ks ratio shows that cox1 has the slowest evolutionary rate. The secondary structure of trnN lacks the Pseudouracil loop (TψC loop) in most Lethe species. The inferred phylogenetic analyses show that Lethe is a well-supported monophyletic group, and reveal 2 major clades within the genus Lethe, which is consistent with previous morphological classifications.
