Reminiscence therapy is revealed to improve cognitive function and attenuate psychological disorders in neurological diseases such as Alzheimer's disease patients, while its application in acute ischemic stroke (AIS) is seldom reported. So, the current study aimed to explore the effect of reminiscence therapy on cognitive impairment, anxiety, depression, and disease recurrence in AIS patients.
A total of 216 first-ever AIS patients were enrolled and randomized into reminiscence therapy group or control group in 11 ratio. MMSE, HADS, and Zung SAS/SDS scales were evaluated at the discharge from hospital (M0), 3months (M3), 6months (M6), 9months (M9), and 12months (M12), respectively. Besides, patients were further followed up to 36months for recurrence-free survival (RFS) calculation.
Reminiscence therapy group showed higher MMSE score at M9 and M12, lower cognitive impairment rate by MMSE at M12 compared to control group. As to anxiety, HADS-anxiety score and anxiety rate by HADS were of no difference at each time point, while SAS score and anxiety rate by SAS were lower at M12 in reminiscence therapy group compared with control group. Regarding depression, HADS-depression score and depression rate by HADS at M12, SDS score at M9 and M12, and depression rate by SDS at M12 were all lower in reminiscence therapy group compared with control group. In terms of RFS, it was similar between reminiscence therapy group and control group.
Reminiscence therapy cripples cognitive impairment, anxiety, and depression, but does not affect RFS in AIS patients, indicating its potential for post-stroke management.

The aim of this study is to share autopsy findings of COVID-19-positive cases and autopsy algorithms for safely handling of suspicious bodies during this pandemic.
COVID-19-positive cases of Istanbul Morgue Department were retrospectively analyzed. Sampling indications for PCR tests in suspicious deaths, macroscopic and microscopic findings obtained in cases with positive PCR tests were evaluated.
In the morgue department, 345(25.8%) of overall 1336 autopsy cases were tested for COVID-19. PCR test was found positive in 26 cases. Limited autopsy procedure was performed in 7 cases, while the cause of death was determined by external examination in the remaining 19 cases. Male-to-female ratio was found 3.31 and mean age was 60.0±13.6 among all PCR-positive cases. Cause of death was determined as viral pneumonia in fully autopsied cases. Most common findings were sticky gelatinous fluid in cavities and firm and swollen lungs, varying degrees of consolidation. In microscopy, diffuse alveolar epithelial damage, type-II pneumocyte hyperplasia, hyaline membrane formation, fibrinous exudate, and fibrinous plaques in the alveoli were the most common findings.
In COVID-19 autopsies, pulmonary findings were found to be prominent and the main pathology was pneumonia. Older age and findings of chronic diseases indicate that the cases were in the multirisk group in terms of COVID-19 mortality.

The coronavirus pandemic resulted in dramatic changes and challenges to healthcare practices. We endeavoured to establish the experiences of families of children attending a neurodevelopmental service after a transition to virtual consultations.
Anonymous questionnaires were posted to parents of children registered in virtual clinics over a 10-week period.
Thirty parental questionnaires were completed. Parents reported a very high level of satisfaction (8.2/10) with previous face-to-face clinic appointments and virtual consultations (8.2/10). Individual aspects of virtual consultations received very positive ratings. Overall, 77% of parents highlighted a future preference for a combined service of both virtual and face-to-face consultations.
This study highlights the high level of parental satisfaction with the service, but especially satisfaction with the unplanned transition to virtual clinics. Virtual clinics cannot replace the holistic approach gained from face-to-face consultations; however, we iorma that has been developed offers a simple structure for undertaking a virtual consultation that can be adapted to different specialities, integrating the suggestions provided by our service users.As part of an International consortium aiming at the characterization by NMR of the proteins of the SARS-CoV-2 virus, we have obtained the virtually complete assignment of the backbone atoms of the non-structural protein nsp9. This small (12 kDa) protein is encoded by ORF1a, binds to RNA and seems to be essential for viral RNA synthesis. The crystal structures of the SARS-CoV-2 protein and other homologues suggest that the protein is dimeric as also confirmed by analytical ultracentrifugation and dynamic light scattering. Our data constitute the prerequisite for further NMR-based characterization, and provide the starting point for the identification of small molecule lead compounds that could interfere with RNA binding and prevent viral replication.Human respiratory syncytial virus (RSV) is highly contagious and the leading cause of severe respiratory tract illness in infants, elderly, and immunocompromised individuals. Toll-like receptor 7 (TLR7), a pattern recognition receptor recognising the ssRNA of RSV, activates proinflammatory pathways and triggers secretion of interferons (IFNs). On the one hand, the inflammatory responses help clear out virus. On the other hand, they lead to severe lung damage. Banlangen is a traditional Chinese herbal medicine commonly prescribed for respiratory virus infection treatment, but the mechanisms of action and active components remain largely unknown. In the present study, we investigated the effects of the main active components of total alkaloids from banlangen (epigoitrin, indole-3-carboxaldehyde, indole-3-acetonitrile and 4-methoxyindole-3-acetonitrile) on the RSV-induced inflammatory responses in mouse macrophage cells (RAW264.7). Our results demonstrated that RSV-induced IFN-α excessive secretion was moderately inhibited by indole-3-carboxaldehyde through downregulation of mRNA expression in a dose-dependent manner, in comparison, the inhibitory effects of ribavirin were too strong. Furthermore, we revealed that indole-3-carboxaldehyde suppressed transcription of IFN-α by inhibiting RSV-induced TLR7 expression in RAW264.7 cells. Additionally, indole-3-carboxaldehyde inhibited RSV-induced NF-κB signalling activation in a TLR7-MyD88-dependent manner. Together, our findings suggest that indole-3-carboxaldehyde inhibited RSV-induced inflammatory injury by moderate regulation of TLR7 signaling pathway and did not significantly affect the viral clearance competence of the innate immune system.Intracerebral hemorrhage (ICH) is a severe neurological disorder with no proven treatment. Inflammation after ICH contributes to clinical outcomes, but the relevant molecular mechanisms remain poorly understood. In studies of peripheral leukocyte counts and mRNA-sequencing (mRNA-seq), our group previously reported that monocytes and Interleukin-8 (IL-8) were important contributors to post-ICH inflammation. microRNA (miRNA) are powerful regulators of gene expression and promising therapeutic targets. We now report findings from an integrated analysis of miRNA-seq and mRNA-seq in peripheral blood mononuclear cells (PBMCs) from a swine ICH model. In 10 pigs, one PBMC sample was collected immediately prior to ICH induction and a second 6 h later; miRNA-seq and mRNA-seq were completed for each sample. An aggregate score calculation determined which miRNA regulated the differentially expressed mRNA. Networks of molecular interactions were generated for the combined miRNA/target mRNA. A total of 227 miRNA were identified, and 46 were differentially expressed after ICH (FDR less then 0.05). The anti-inflammatory miR-181a was decreased post-ICH, and it was the most highly connected miRNA in the miRNA/mRNA bioinformatic network analysis. miR-181a has interconnected pathophysiology with IL-8 and monocytes; in prior studies, we found that IL-8 and monocytes contributed to post-ICH inflammation and ICH clinical outcome, respectively. miR-181a was a significant mediator of post-ICH inflammation and is promising for further study, including as a potential therapeutic target. This investigation also demonstrated feasible methodology for miRNA-seq/mRNA-seq analysis in swine that is innovative, and with unique challenges, compared with transcriptomics research in more established species.Cardiovascular diseases are one of the leading causes of mortality in the western world. Myocardial infarction is among the most prevalent and results in significant cell loss within the myocardium. Similarly, numerous drugs have been identified as having cardiotoxic side effects. The adult human heart is however unable to instigate an effective repair mechanism and regenerate the myocardium in response to such damage. This is in large part due to the withdrawal of cardiomyocytes (CMs) from the cell cycle. Thus, identifying, screening, and developing agents that could enhance the proliferative capacity of CMs holds great potential in cardiac regeneration. Human induced pluripotent stem cells (hiPSCs) and their cardiovascular derivatives are excellent tools in the search for such agents. This chapter outlines state-of-the art techniques for the two-dimensional differentiation and attainment of hiPSC-derived CMs and endothelial cells (ECs). Bioreactor systems and three-dimensional spheroids derived from hiPSC-cardiovascular derivatives are explored as platforms for drug discovery before focusing on relevant assays that can be employed to assess cell proliferation and viability.Cancer stem cells (CSCs) are capable of continuous proliferation and self-renewal and are proposed to play significant roles in oncogenesis, tumor growth, metastasis, and cancer recurrence. CSCs are considered derived from normal stem cells affected by the inflammatory microenvironment. selleckchem Stem cells, are considered to be induced into progenitor cells, which differentiate into various normal phenotypes depending on the normal niche. We hypothesized that CSCs could be derived from stem cells in the cancer-inducing niche, which is a condition of chronic inflammation rich in growth factors, interleukins, chemokines, etc. Exosomes are considered to be the key mediators responsible for the cell-to-cell communications carrying proteins, nucleic acids, metabolites, etc., to shuttle between cells. If these cells are in the environment of chronic inflammation, the exosomes should be reflecting the conditions. In this chapter, we detail the method of CSC initiation using extracellular vesicles (EVs) derived from cancer cell.
