Centriole formation is a highly regulated cellular process and aberrations in centriole structure, size or numbers have implications in multiple human pathologies. In this review, we propose that the proteins that control centriole length can be subdivided into two classes based on their antagonistic activities on centriolar microtubules, which we refer to as 'centriole elongation activators' (CEAs) and 'centriole elongation inhibitors' (CEIs). We discuss and illustrate the structure-function relationship of CEAs and CEIs as well as their interaction networks. Based on our current knowledge, we formulate some outstanding open questions in the field and present possible routes for future studies.Free Energy Landscape theory of Protein Folding, introduced over 20 years ago, implies that a protein has many paths to the folded conformation with the lowest free energy. Despite the knowledge in principle, it has been remarkably hard to detect such pathways. The lack of such observations is primarily due to the fact that no one experimental technique can detect many parts of the protein simultaneously with the time resolution necessary to see such differences in paths. However, recent technical developments and employment of multiple experimental probes and folding prompts have illuminated multiple folding pathways in a number of proteins that had all previously been described with a single path.Polynucleotide kinase phosphatase (PNKP) has dual enzymatic activities as kinase and phosphatase for DNA ends, which are the prerequisite for the ligation, and thus is involved in base excision repair, single-strand break repair and non-homologous end joining for double-strand break (DSB) repair. EstradiolBenzoate In this study, we examined mechanisms for the recruitment of PNKP to DNA damage sites by laser micro-irradiation and live-cell imaging analysis using confocal microscope. We show that the forkhead-associated (FHA) domain of PNKP is essential for the recruitment of PNKP to DNA damage sites. Arg35 and Arg48 within the FHA domain are required for interactions with XRCC1 and XRCC4. PNKP R35A/R48A mutant failed to accumulate on the laser track and siRNA-mediated depletion of XRCC1 and/or XRCC4 reduced PNKP accumulation on the laser track, indicating that PNKP is recruited to DNA damage sites via the interactions between its FHA domain and XRCC1 or XRCC4. Furthermore, cells expressing PNKP R35A/R48A mutant exhibited increased sensitivity toward ionizing radiation in association with delayed SSB and DSB repair and genome instability, represented by micronuclei and chromosome bridges. Taken together, these findings revealed the importance of PNKP recruitment to DNA damage sites via its FHA domain for DNA repair and maintenance of genome stability.
People with Borderline Personality Disorder (BPD) have limited access to long term psychological therapies. Briefer interventions have been developed but trial evidence to support their use has not been reviewed.
To examine whether psychological interventions for adults with BPD of six months duration or less improve symptoms, mood, self-harm, suicidal behaviour, and service use.
The protocol was prospectively registered (PROSPERO CRD42017063777). Database searches were conducted up to April 2020. Inclusion, data extraction and risk of bias were assessed in duplicate. We identified 27 randomised controlled trials. We conducted random-effects meta-analyses sub-grouping data into delivery method, additional support, and comparison type.
High levels of bias were found for attrition and reporting. Heterogeneity was high in some pooled data. Borderline symptom reductions were greatest for interventions including additional support (SMD. -1.23, 95% C.I. -2.13, -0.33). Planned generic support may be as effective as specialist interventions for borderline symptoms (SMD=-0.11, 95% C.I. -0.51, 0.29) and social functioning (SMD=-0.16., 95% C.I. -0.65, 0.33). Follow-up was limited and direct comparison with post-intervention results was unreliable.
Short-term interventions may be effective. Access to additional support has an impact on outcomes. It is unclear if symptomatic change is sustained.

In a race to contain the infection, researchers and healthcare officials have developed several assays to help diagnose individuals with COVID-19. To help laboratories decide what assay to bring into testing lines, factors such as assay availability, cost, throughput, and TAT should be considered. Here we validated a modified version of the CDC assay and used it as a reference to evaluate the performance of the NeuMoDxTM SARS-CoV-2 and DiaSorin SimplexaTM Covid-19 Direct assays. In silico analysis and clinical sample testing showed that the primers/probes designed by the CDC were specific to the SARS-CoV-2 as they accurately detected all reactive samples with an assay LoD of 200 copies/mL. The performance of the three assays were analyzed using 159 nasopharyngeal swabs specimen tested within 1-5 days after routine testing. A 100 % agreement was observed between the commercial assays and the modified CDC SARS-CoV-2 assay. A deeper look at the Ct values showed no significant difference between NeuMoDx and the modified CDC SARS-CoV-2 assay, whereas DiaSorin had lower overall Ct values than the modified CDC SARS-CoV-2 assay. NeuMoDx and DiaSorin workflows were much easier to perform. NeuMoDx has the highest throughput and shortest TAT, whereas although the modified CDC SARS-CoV-2 assay has comparable throughput to DiaSorin, it has the longest hands-on time and highest TAT.
With the introduction of molecular diagnostic techniques over the past decades, different kinds of viral pathogens in the same sample are detected simultaneously more frequently. Nevertheless, influenza virus (Flu) and respiratory syncytial virus (RSV) coinfection in adults was reported only occasionally. Moreover, the clinical implications of Flu/RSV coinfection in the respiratory tract of adults remain unclear.
This retrospective study analyzed adult patients with acute respiratory infection from January 2017 to June 2019 in China-Japan Friendship Hospital.
A total of 574, 235 and 113 patients were positive for influenza A-only (FA-only), influenza B-only (FB-only) and RSV-only in influenza seasons (from Nov 2017 to Mar 2018 and from Nov 2018 to Mar 2019), respectively. Of these, 19 cases were coinfected by Flu and RSV and admitted to this hospital. Compared with 809 Flu-only infected patients and 113 RSV-only infected patients, both the rates of intensive care unit(ICU) admission and use of invasive mechanical ventilation in Flu/RSV coinfected patients were higher (ICU admission 47.
