Recent Overview of the Use of iPSCs Huntington’s Disease Modeling and Therapy

Huntington’s disease (HD) is an inherited, autosomal dominant, degenerative disease characterized by involuntary movements, cognitive decline, and behavioral impairment ending in death. HD is caused by an expansion in the number of CAG repeats in the huntingtin gene on chromosome 4. To date, no effective therapy for preventing the onset or progression of the disease has been found, and many symptoms do not respond to pharmacologic treatment. However, recent results of pre-clinical trials suggest a beneficial effect of stem-cell-based therapy. Induced pluripotent stem cells (iPSCs) represent an unlimited cell source and are the most suitable among the various types of autologous stem cells due to their patient specificity and ability to differentiate into a variety of cell types both in vitro and in vivo. Furthermore, the cultivation of iPSC-derived neural cells offers the possibility of studying the etiopathology of neurodegenerative diseases, such as HD. Moreover, differentiated neural cells can organize into three-dimensional (3D) organoids, mimicking the complex architecture of the brain. In this article, we present a comprehensive review of recent HD models, the methods for differentiating HD–iPSCs into the desired neural cell types, and the progress in gene editing techniques leading toward stem-cell-based therapy.
Laparoscopic Cholecystectomy in Kartagener Syndrome

Kartagener syndrome is a rare autosomal recessive disorder in which there is situs inversus involving abdominal or thoracic viscera or both. Anatomy of the abdominal organs in such a patient is distorted making laparoscopic surgery very difficult. A 45-year-old lady, a known case of Kartagener syndrome, presented with epigastric pain. Ultrasound of abdomen revealed situs inversus with mild hepatomegaly and multiple gallbladder calculi. Magnetic resonance pancreatocholangiography (MRCP) confirmed situs inversus totalis with cholelithiasis and mild central intrahepatic biliary dilatation. Patient was treated successfully with laparoscopic cholecystectomy.
Cocktail Treatment with a Gelatin Sponge Impregnated with Ropivacaine, Dexamethasone, and Vitamin B12 Promotes Early Postoperative Recovery after Percutaneous Endoscopic Lumbar Discectomy: A Retrospective, Case-Controlled Study.

BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) can only relieve mechanical compression but cannot directly reduce the inflammatory reaction of the adjacent nerve root, which contributes to persistent pain and physical disabilities postoperatively. Numerous studies have explored the application of epidural steroids after an open lumbar discectomy in relieving pain by reducing local inflammatory reactions and further peridural scar formation. OBJECTIVES To explore that whether "cocktail treatment" in which a gelatin sponge was impregnated with ropivacaine, dexamethasone, and vitamin B12 promoted early postoperative recovery after PELD. STUDY DESIGN Retrospective, case-controlled study. SETTING All data were from Hong-Hui Hospital in Xi'an. METHODS Between January 2016 and January 2017, 100 patients of single-level lumbar disc herniation were treated with PELD in our hospitals. The cocktail treatment was applied in the first 50 patients (group cocktail), and an equal size gelatin sponge without drugs was used in the other 50 patients as control (group noncocktail). The clinical outcome evaluation included the Visual Analog Scale (VAS) score for back and leg pain and Oswestry Disability Index (ODI) score. RESULTS There was a significant difference in the mean periods of return to work (4.25 ± 1.88 weeks in the cocktail group and 5.18 ± 2.19 weeks in the noncocktail group) (P < 0.01). Compared with the preoperative data, a significant improvement in VAS scores of back pain and sciatica and ODI were observed in each follow-up interval (P < 0.05, respectively). In the noncocktail group, there were visible fluctuations in the 3 indicators within the first week after surgery. This phenomenon was not observed in the cocktail group, a difference that was statistically significant (P < 0.05, respectively). In further follow-up, no significant differences were observed between the 2 groups (P > 0.05, respectively). LIMITATIONS The nonrandomized, single-center, retrospective design is a major limitation of this study. CONCLUSIONS The "cocktail treatment" with a gelatin sponge impregnated with ropivacaine, dexamethasone, and vitamin B12 promotes early and satisfactory back and leg pain relief and fast functional recovery after PELD. KEY WORDS Endoscopic lumbar discectomy, lumbar disc herniation, steroids, nerve root block, gelatin sponge.
Structural and biochemical characterization of SADS‐CoV papain‐like protease 2

Swine acute diarrhea syndrome coronavirus (SADS‐CoV) is a novel coronavirus that is involved in severe diarrhea disease in piglets, causing considerable agricultural and economic loss in China. The emergence of this new coronavirus increases the importance of understanding SADS‐CoV as well as antivirals. Coronaviral proteases, including main proteases and papain‐like proteases (PLP), are attractive antiviral targets because of their essential roles in polyprotein processing and thus viral maturation. Here, we describe the biochemical and structural identification of recombinant SADS papain‐like protease 2 (PLP2) domain of nsp3. The SADS‐CoV PLP2 was shown to cleave nsp1 proteins and also peptides mimicking the nsp2|nsp3 cleavage site and also had deubiquitinating and deISGynating activity by in vitro assays. The crystal structure adopts an architecture resembling that of PLPs from other coronaviruses. We characterize both conserved and unique structural features likely directing the interaction of PLP2 with the substrates, including the tentative mapping of active site and other essential residues. These results provide a foundation for understanding the molecular basis of coronaviral PLPs' catalytic mechanism and for the screening and design of therapeutics to combat infection by SADS coronavirus.
Older Adult Productive Activity Participation Using the National Health and Aging Trends Study

This study aims to characterize factors related to productive activity participation among community-dwelling older adults. Cross-sectional analyses using data from the National Health and Aging Trends Study were used to calculate weighted frequencies representative of the U.S. population of older adults. Multivariate logistic regression was used to explore factors related to participation outcomes (paid work, volunteering, caregiving). We found that 21% of community-dwelling older adults in the United States reported currently working. Older adults reported working in a wide range of occupations. Driving emerged as one of the most important factors related to increased odds of productive activity participation. Age, gender, and health factors were also significantly associated with increased odds of productive activity participation. By understanding the current profile of participation in activities including employment, caregiving, and volunteering among a national sample of community-dwelling older adults, we can effectively inform intervention programs and resource allocation to support productive aging.
Disease-Management-Programs in the Field of Diabetes Mellitus with Identification of the Best Practice in Europe: A Scoping Review

Abstract The objective of this scoping review was to create an up-to-date descriptive overview of published Disease-Management-Program evaluations conducted within Europe. We also assessed the methodological quality of the evaluation and the comparability of the included studies. The Databases Pub Med via Medline and Embase via Ovid were searched for thematically fitting publications. Out of 649 initial titles and abstracts, 45 full-texts were screened for inclusions. Finally, 21 publications met all inclusion criteria. DMPs from Germany, Austria, Italy, the Netherlands and Great Britain were included. The results are tabulated in the results section and discussed descriptively. Due to the heterogeneity of the included studies and the application of sometimes potentially biased study design comparisons were difficult. A uniform European-wide evaluation strategy and common quality features would be desirable.
The Effectiveness of Daily and Alternate Day Oral Iron Supplementation in Athletes With Suboptimal Iron Status (Part 2).

The authors compared the effectiveness of daily (DAY) versus alternate day (ALT) oral iron supplementation in athletes with suboptimal iron. Endurance-trained runners (nine males and 22 females), with serum ferritin (sFer) concentrations <50 μg/L, supplemented with oral iron either DAY or ALT for 8 weeks. Serum ferritin was measured at baseline and at fortnightly intervals. Hemoglobin mass (Hbmass) was measured pre- and postintervention in a participant subset (n = 10). Linear mixed-effects models were used to assess the effectiveness of the two strategies on sFer and Hbmass. There were no sFer treatment (p = .928) or interaction (p = .877) effects; however, sFer did increase (19.7 μg/L; p < .001) over the 8-week intervention in both groups. In addition, sFer was 21.2 μg/L higher (p < .001) in males than females. No Hbmass treatment (p = .146) or interaction (p = .249) effects existed; however, a significant effect for sex indicated that Hbmass was 140.85 g higher (p = .004) in males compared with females. Training load (p = .001) and dietary iron intake (p = .015) also affected Hbmass. Finally, there were six complaints of severe gastrointestinal side effects in DAY, but only one in ALT. In summary, both supplement strategies increased sFer in athletes with suboptimal iron status; however, the ALT approach was associated with lower incidence of gastrointestinal upset.
Effect of Ionizing Radiation on Transcriptome during Neural Differentiation of Human Embryonic Stem Cells

Human embryonic brain development is highly sensitive to ionizing radiation. However, detailed information on the mechanisms of this sensitivity is not available due to limited experimental data. In this study, differentiation of human embryonic stem cells (hESCs) to neural lineages was used as a model for early embryonic brain development to assess the effect of exposure to low (17 mGy) and high (572 mGy) doses of radiation on gene expression. Transcriptomes were assessed using RNA sequencing during neural differentiation at three time points in control and irradiated samples. The first time point was when the cells were still pluripotent (day 0), the second time point was during the stage of embryoid body formation (day 6), and the third and final time point was during the stage of neural rosette formation (day 10). Analysis of the transcriptomes revealed neurodifferentiation in both the control and irradiated cells. Low-dose irradiation did not result in changes in gene expression at any of the time points, whereas high-dose irradiation resulted in downregulation of some major neurodifferentiation markers on days 6 and 10. Gene ontology analysis showed that pathways related to nervous system development, neurogenesis and generation of neurons were among the most affected. Expression of such key regulators of neuronal development as NEUROG1, ARX, ASCL1, RFX4 and INSM1 was reduced more than twofold. In conclusion, exposure to a 17 mGy low dose of radiation was well tolerated by hESCs while exposure to 572 mGy significantly affected their genetic reprogramming into neuronal lineages.
Sarcopenia predicts prognosis of patients with renal cell carcinoma: A systematic review and meta-analysis

ABSTRACT Sarcopenia, a concept reflecting the loss of skeletal muscle mass, was reported to be associated with the prognosis of several tumors. However, the prognostic value of sarcopenia in patients with renal cancer remains unclear. We carried out this metaanalysis and systematic review to evaluate the prognostic value of sarcopenia in patients with renal cell carcinomas. We comprehensively searched PubMed, Embase, and Cochrane Library from inception to December 2018. Hazard ratio (HR) and 95% confidence interval (CI) were pooled together. A total of 5 studies consisting of 771 patients were enrolled in this quantitative analysis, 347 (45.0%) of which had sarcopenia. Patients with sarcopenia had a worse OS compared with those without sarcopenia (HR=1.76; 95%CI, 1.35-2.31; P <0.001). In the subgroup of patients with localized and advanced/metastatic diseases, sarcopenia was also associated with poor OS (HR=1.48, P=0.039; HR=2.14, P <0.001; respectively). With a limited sample size, we did not observe difference of PFS between two groups (HR=1.56, 95% CI, 0.69-3.50, P=0.282). In the present meta-analysis, we observed that patients with sarcopenia had a worse OS compared with those without sarcopenia in RCC. Larger, preferably prospective studies, are needed to confirm and update our findings.
Understanding the Ecological Validity of Relying Practice as a Basis for Risk Identification

Understanding the reliability of hazardous organizations and their protective systems is central to understanding the risk they produce. Work on “high reliability organization” has done much to illuminate the conditions in which social organization becomes reliable in highly demanding conditions. But risk depends just as much on how relying entities do their relying as it does on the reliability of the entities they rely on. Patterns of relying are often opaque in sociotechnical systems, and processes of relying and being relied on are mutually influencing in complex ways, so the relationship between relying and risk may not be at all obvious. This study was an attempt to study relying as a social practice, in particular analyzing how it had ecological validity in a social organization—how practice was responsive to the conditions in which it took place. This involved observational fieldwork and inductive, qualitative analysis on an offshore oil and gas production platform that was nearing the end of its design life and undergoing refurbishment. The analysis produced four main categories of ecological validity: responsiveness to formal organization, responsiveness to situational contingency, responsiveness to information asymmetry, and responsiveness to sociomateriality. This ecological validity of relying practice should be a primary focus of risk identification, assessing how relying can become mismatched to reliability in certain ways, both when relying practice is responsive to circumstances and when it is not.
Hippo-YAP1 Is a Prognosis Marker and Potentially Targetable Pathway in Advanced Gallbladder Cancer

Gallbladder cancer is an aggressive disease with late diagnosis and no efficacious treatment. The Hippo-Yes-associated protein 1 (YAP1) signaling pathway has emerged as a target for the development of new therapeutic interventions in cancers. However, the role of the Hippo-targeted therapy has not been addressed in advanced gallbladder cancer (GBC). This study aimed to evaluate the expression of the major Hippo pathway components mammalian Ste20-like protein kinase 1 (MST1), YAP1 and transcriptional coactivator with PDZ-binding motif (TAZ) and examined the effects of Verteporfin (VP), a small molecular inhibitor of YAP1-TEA domain transcription factor (TEAD) protein interaction, in metastatic GBC cell lines and patient-derived organoids (PDOs). Immunohistochemical analysis revealed that advanced GBC patients had high nuclear expression of YAP1. High nuclear expression of YAP1 was associated with poor survival in GBC patients with subserosal invasion (pT2). Additionally, advanced GBC cases showed reduced expression of MST1 compared to chronic cholecystitis. Both VP treatment and YAP1 siRNA inhibited the migration ability in GBC cell lines. Interestingly, gemcitabine resistant PDOs with high nuclear expression of YAP1 were sensitive to VP treatment. Taken together, our results suggest that key components of the Hippo-YAP1 signaling pathway are dysregulated in advanced gallbladder cancer and reveal that the inhibition YAP1 may be a candidate for targeted therapy.
Miconia lucenae (Melastomataceae), a new species from montane Atlantic Forest in Espírito Santo, Brazil

We describe Miconia lucenae R.Goldenb. & Michelang. , a new species from the montane Atlantic Forest in Santa Teresa in the state of Espírito Santo. Our analysis, based on three plastid spacers (atpF-atpH, psbK-psbl and trnS-trnG), one plastid gene (ndhF, not available for M. lucenae), and two nuclear ribosomal loci (nrITS and nrETS), showed that it belongs to a small clade with Miconia paradoxa (Mart. ex DC.) Triana (Minas Gerais) and M. michelangeliana R.Goldenb. & L.Kollmann (Espírito Santo). The three species in the “Paradoxa clade” can be recognized by the plants with glabrous or glabrescent branches and leaves, white petals and yellow stamens, these with the connectives not prolonged below the thecae, ventrally unappendaged, dorsally unappendaged or with a minute tooth, the latter bilobed or not, glabrous ovary, and the fruits with a persistent calyx. Miconia lucenae can be recognized, among the species in this clade, by the shrubby plants with terete young branches, short inflorescences, usually with red axes, and the 2-bracteolate, sessile, 4-merous flowers, with a ciliolate inner portion of the sepals, lanceolate petals, and 4-celled ovaries. This species can be considered as endangered according to IUCN criteria.
Decision-Making Selector (DMS) for Integrating CCA-Based Methods to Improve Performance of SSVEP-Based BCIs

Objective: Recent research has demonstrated improved performance of a brain-computer interface (BCI) using fusion based approaches. This paper proposes a novel decision-making selector (DMS) to integrate classification decisions of different frequency recognition methods based on canonical correlation analysis (CCA) which were used in decoding steady state visual evoked potentials (SSVEPs). Methods: The DMS method selects a decision more likely to be correct from two methods namely as M1 and M2 by separating the M1-false and M2-false trials. To measure the uncertainty of each decision, feature vectors were extracted using the largest and second largest correlation coefficients corresponding to all the stimulus frequencies. The proposed method was evaluated by integrating all pairs of 7 CCA-based algorithms, including CCA, individual template-based CCA (ITCCA), multi-set CCA (MsetCCA), L1-regularized multi-way CCA (L1-MCCA), filter bank CCA (FBCCA), extended CCA (ECCA), and task-related component analysis (TRCA). Main results: The experimental results obtained from a 40-target dataset of thirty-five subjects showed that the proposed DMS method was validated to obtain an enhanced performance by integrating the algorithms with close accuracies. Conclusion: The results suggest that the proposed DMS method is effective in integrating decisions of different methods to improve the performance of SSVEP-based BCIs.
Associations of maternal resources with care behaviours differ by resource and behaviour

Abstract Care is important for children's growth and development, but lack or inadequacy of resources for care can constrain appropriate caregiving. The objectives of this study were to examine whether maternal resources for care are associated with care behaviours specifically infant and young child feeding, hygiene, health‐seeking, and family care behaviours. The study also examined if some resources for care are more important than others. This study used baseline Alive & Thrive household surveys from Bangladesh, Vietnam, and Ethiopia. Measures of resources for care were maternal education, knowledge, height, nourishment, mental well‐being, decision‐making autonomy, employment, support in chores, and perceived instrumental support. Multiple regression analyses were conducted to examine the associations of resources for care with child‐feeding practices (exclusive breastfeeding, minimum meal frequency, dietary and diversity), hygiene practices (improved drinking water source, improved sanitation, and cleanliness), health‐seeking (full immunization), and family care (psychosocial stimulation and availability of adequate caregiver). The models were adjusted for covariates at child, parents, and household levels and accounted for geographic clustering. All measures of resources for care had positive associations with care behaviours; in a few instances, however, the associations between the resources for care and care behaviours were in the negative direction. Improving education, knowledge, nutritional status, mental well‐being, autonomy, and social support among mothers would facilitate provision of optimal care for children.
Predominance of Human Bocavirus Genotype 1 and 3 in Outpatient Children with Diarrhea from Rural Communities in South Africa, 2017–2018

Human bocavirus (HBoV) is an emerging virus globally associated with diarrhea in young children. This study aims to investigate the prevalence of HBoV genotypes in children (≤5 years) from rural communities in South Africa (SA) suffering from acute gastroenteritis (AGE). A total of 141 fecal samples of children ≤5 years with acute gastroenteritis (AGE) were collected from rural primary health care facilities in the Vhembe district of SA between June 2017 and July 2018. Clinical symptoms and demographic data were also recorded. A total of 102 (72%) were outpatients, and 39 (28%) were hospitalized patients. Human bocavirus (HBoV) genotypes were determined using real-time multiplex PCR. DNA extracts of positive samples were confirmed by conventional PCR targeting the NS1 gene. Co-infection with other enteric viruses were determined in HBoV-positive samples using real-time PCR. HBoV was detected in eight (5.7%) children with AGE, of which three (37.5%) were HBoV1, three (37.5%) were HBoV3, and two (25%) were HBoV2. The majority of positive cases were identified in outpatients (62%) between the ages of 1 and 24 months. Co-infection in HBoV-positive samples with other enteric viruses included rotavirus (37.5%), adenovirus (37.5%), norovirus (25%), and astrovirus (12.5%). HBoV infections could be seen as a potential emerging diarrheal pathogen in South Africa. However, more studies are needed to understand the role of HBoV infections in children with AGE.
Synthesis, antimicrobial activity, molecular docking and ADMET study of a caprolactam-glycine cluster

Abstract Density functional theory calculations were performed with DFT method using both b3lyp/6-311++G(d,p) and wb97xd/6-311++G(d,p) levels of theory to predict the molecular geometry, to evaluate the molecular electrostatic potential and frontier molecular orbitals of synthesized a new compound: caprolactam-glysine cluster (CL-Gly). Molecular docking study of the CL-Gly was carried out to clarify the interaction and the probable binding modes, between the title compound and DNA. The antibacterial activities of CL-Gly cluster against Gram-positive and Gram-negative bacteria was determined. In silico ADMET study was also performed for predicting pharmacokinetic and toxicity profile of the synthesized cluster which expressed good drug-like behavior and non-toxic nature. It was revealed that the compound has importance in drug discovery process. Communicated by Ramaswamy H. Sarma
Effect of soluble-viscous dietary fibre on coronary heart disease risk score across three population health categories: Data from randomized, double-blind, placebo controlled trials.

We applied the Framingham risk equation in healthy, metabolic syndrome, and diabetes populations, following treatment with viscous fibre from konjac-based blend (KBB). KBB yielded reduction in estimated risk score by 16% (1.04±0.03vs.0.87±0.04, p<0.01) in type 2 diabetes, 24% (1.08±0.01vs.0.82±0.02, p<0.01) in metabolic syndrome, and 25% (1.09±0.05vs.0.82±0.06, p<0.01) in healthy individuals. Drivers for decreased risk were improvements in blood cholesterol and systolic blood pressure. The composite coronary heart disease risk across populations was reduced 22% (p<0.01). Novelty Bullet: Viscous fibre from konjac-xanthan reduced 10-y relative CHD using Framingham Risk Score across the glycemic status spectrum.
