- Patient-perceived quality of inpatient/outpatient psychiatric care remains under-researched. A cross-sectional survey with purposive sampling comprising 567 inpatients and 549 outpatients was conducted among eight psychiatric care facilities in Taiwan to examine the factors influencing patient-perceived care quality. Inpatients and outpatients perceived moderate quality of care, where "Encounter" was reported as the highest dimension. Inpatients perceived "Secure environment" as the lowest; outpatients rated "Discharge/Referring" as the lowest. Hospital region and customer loyalty were significantly associated with patient-perceived care quality. Other significant factors were also identified: inpatient employment, perceived mental health and treatment effects, understanding diagnosis, previous treatment, and visited by appointment.

AXL promotes Zika virus infection in astrocytes by antagonizing type I interferon signalling

- Zika virus (ZIKV) is associated with neonatal microcephaly and Guillain-Barre syndrome(1,2). While progress has been made in understanding the causal link between ZIKV infection and microcephaly(3-9), the life cycle and pathogenesis of ZIKV are less well understood. In particular, there are conflicting reports on the role of AXL, a TAM family kinase receptor that was initially described as the entry receptor for ZIKV(10-22). Here, we show that while genetic ablation of AXL protected primary human astrocytes and astrocytoma cell lines from ZIKV infection, AXL knockout did not block the entry of ZIKV. We found, instead, that the presence of AXL attenuated the ZIKV-induced activation of type I interferon (IFN) signalling genes, including several type I IFNs and IFN-stimulating genes. Knocking out type I IFN receptor alpha chain (IFNAR1) restored the vulnerability of AXL knockout astrocytes to ZIKV infection. Further experiments suggested that AXL regulates the expression of SOCS1, a known type I IFN signalling suppressor, in a STAT1/STAT2-dependent manner. Collectively, our results demonstrate that AXL is unlikely to function as an entry receptor for ZIKV and may instead promote ZIKV infection in human astrocytes by antagonizing type I IFN signalling.

The first visual object tracking segmentation VOTS2023 challenge results
- 2023

Ingår i: 2023 IEEE/CVF International conference on computer vision workshops (ICCVW). - : Institute of Electrical and Electronics Engineers Inc.. - 9798350307443 - 9798350307450 ; , s. 1788-1810

- The Visual Object Tracking Segmentation VOTS2023 challenge is the eleventh annual tracker benchmarking activity of the VOT initiative. This challenge is the first to merge short-term and long-term as well as single-target and multiple-target tracking with segmentation masks as the only target location specification. A new dataset was created; the ground truth has been withheld to prevent overfitting. New performance measures and evaluation protocols have been created along with a new toolkit and an evaluation server. Results of the presented 47 trackers indicate that modern tracking frameworks are well-suited to deal with convergence of short-term and long-term tracking and that multiple and single target tracking can be considered a single problem. A leaderboard, with participating trackers details, the source code, the datasets, and the evaluation kit are publicly available at the challenge website1

- The Visual Object Tracking challenge VOT2021 is the ninth annual tracker benchmarking activity organized by the VOT initiative. Results of 71 trackers are presented; many are state-of-the-art trackers published at major computer vision conferences or in journals in recent years. The VOT2021 challenge was composed of four sub-challenges focusing on different tracking domains: (i) VOT-ST2021 challenge focused on short-term tracking in RGB, (ii) VOT-RT2021 challenge focused on "real-time" short-term tracking in RGB, (iii) VOT-LT2021 focused on long-term tracking, namely coping with target disappearance and reappearance and (iv) VOT-RGBD2021 challenge focused on long-term tracking in RGB and depth imagery. The VOT-ST2021 dataset was refreshed, while VOT-RGBD2021 introduces a training dataset and sequestered dataset for winner identification. The source code for most of the trackers, the datasets, the evaluation kit and the results along with the source code for most trackers are publicly available at the challenge website(1).

Crystal structure of tubulin folding cofactor A from Arabidopsis thaliana and its beta-tubulin binding characterization

- Microtubules are composed of polymerized alpha/beta-tubulin heterodimers. Biogenesis of assembly-competent tubulin dimers is a complex multistep process that requires sequential actions of distinct molecular chaperones and cofactors. Tubulin folding cofactor A (TFCA), which captures beta-tubulin during the folding pathway, has been identified in many organisms. Here, we report the crystal structure of Arabidopsis thaliana TFC A (KIESEL, KIS), which forms a monomeric three-helix bundle. The functional binding analysis demonstrated that KIS interacts with beta-tubulin in plant. Furthermore, mutagenesis studies indicated that the alpha-helical regions of KIS participate in beta-tubulin binding. Unlike the budding yeast TFC A, the two loop regions of KIS are not required for this interaction suggesting a distinct binding mechanism of TFC A to beta-tubulin in plants.

- Tubulin-folding cofactor A (TFC A) is a molecular post-chaperonin that is involved in the beta-tubulin-folding pathway. It has been identified in many organisms including yeasts, humans and plants. In this work, Arabidopsis thaliana TFC A was expressed in Escherichia coli and purified to homogeneity. After thrombin cleavage, a well diffracting crystal was obtained by the sitting-drop vapour-diffusion method at 289 K. The crystal diffracted to 1.6 A resolution using synchrotron radiation and belonged to space group I4(1), with unit-cell parameters a=55.0, b=55.0, c=67.4 A.
