Social Participation Among Older Adults Receiving Community Care Services

Aged care services have the potential to support social participation for the growing number of adults aging at home, but little is known about the types of social activities older adults in community care are engaged in. We used cluster analysis to examine the current profiles of social participation across seven domains in 1,114 older Australians, and chi-square analyses to explore between-group differences in social participation and sociodemographic and community care service use. Two distinct participation profiles were identified: (a) connected, capable, older rural women and (b) isolated, high-needs, urban-dwelling men. The first group had higher levels of engagement across six social participation domains compared with the second group. Social participation among older adults receiving community care services varies by gender, age, individual care needs, and geographical location. More targeted service provision at both the individual and community levels may assist older adults to access social participation opportunities.
Optimal Switching Instants for the Control of Hybrid Systems

The problem of determining optimal switching instants for the control of hybrid systems under reachability constraints is considered. This optimization problem is cast into an interval global optimization problem with differential constraints, where validated simulation techniques and dynamic time meshing are used for its solution. The approach is applied on two examples, one being the well-known example of the Goddard's problem where a rocket has to reach a given altitude while consuming the smallest amount of fuel.
Isolation of murine bone marrow by centrifugation or flushing for the analysis of hematopoietic cells – a comparative study

Abstract Investigation of the bone marrow as the main compartment of hematopoiesis is critical in many research fields. Here, we adapted a centrifugation-based method for the isolation of murine bone marrow and compared it to the traditional flushing method. Analysis of primary hematopoietic stem cells, immune cells, and megakaryocytes revealed a comparable distribution of cellular (sub)populations. Furthermore, in vitro differentiated megakaryocytes displayed unaltered proplatelet formation. Strikingly, bone marrow isolation by centrifugation was considerably faster than the flushing method and significantly increased the cell yield. Thus, the centrifugation-based isolation method is highly suitable for the study of murine bone marrow cells.
Potential mechanisms of action of celastrol against rheumatoid arthritis: Transcriptomic and proteomic analysis

Background The natural triterpene celastrol exhibits potential anti-inflammatory activity in inflammatory diseases such as rheumatoid arthritis (RA). Methods Here we explored through what proteins and processes celastrol may act in activated fibroblast-like synoviocytes (FLS) from RA patients. Differential expression of genes and proteins after celastrol treatment of FLS was examined using RNA sequencing, label-free relatively quantitative proteomics and molecular docking. Results Expression of 26,565 genes and 3,372 proteins was analyzed. Celastrol was associated with significant changes in genes that respond to oxidative stress and oxygen levels, as well as genes that stabilize or synthesize components of the extracellular matrix. Conclusions These results identify several potential mechanisms through which celastrol may inhibit inflammation in RA.
Porphyra migitae sp. nov. (Bangiales, Rhodophyta) from Japan

Kikuchi N. , Arai S. , Yoshida G. , Shin J.-A. , Broom J.E. , Nelson W.A. and Miyata M. 2010. Porphyra migitae sp. nov. (Bangiales, Rhodophyta) from Japan. Phycologia 49: 345–354. DOI: 10.2216/09-82.1 A new species of Porphyra, Porphyra migitae sp. nov., coloured fire red and collected subtidally in two localities in Japan, is described based on morphology, life history and molecular analyses. The new species can be distinguished from other fire-red coloured Porphyra species by a range of characters including the presence of conchospores and many archeospores and neutral spores on foliose thalli. Foliose thalli, which are sometimes lobed, are monoecious, and clearly distinguishable patches of spermatangial sori are not formed. Many holes are formed on the foliose thalli after release of spermatia. This species has a heteromorphic life history in which the macroscopic gametophytic foliose thalli alternate with the microscopic sporophytic filamentous thalli (conchocelis). In addition, the life history includes additional reproductive cycles of the foliose thalli via archeospores and neutral spores. This species has the widest range of asexual reproductive strategies so far observed in the Bangiales. Molecular phylogenies based on both the nuclear SSU rDNA and the rbcL genes enable this species to be distinguished from other species of Porphyra for which there are equivalent data.
The ComX Quorum Sensing Peptide of Bacillus subtilis Affects Biofilm Formation Negatively and Sporulation Positively

Quorum sensing (QS) is often required for the formation of bacterial biofilms and is a popular target of biofilm control strategies. Previous studies implicate the ComQXPA quorum sensing system of Bacillus subtilis as a promoter of biofilm formation. Here, we report that ComX signaling peptide deficient mutants form thicker and more robust pellicle biofilms that contain chains of cells. We confirm that ComX positively affects the transcriptional activity of the PepsA promoter, which controls the synthesis of the major matrix polysaccharide. In contrast, ComX negatively controls the PtapA promoter, which drives the production of TasA, a fibrous matrix protein. Overall, the biomass of the mutant biofilm lacking ComX accumulates more monosaccharide and protein content than the wild type. We conclude that this QS phenotype might be due to extended investment into growth rather than spore development. Consistent with this, the ComX deficient mutant shows a delayed activation of the pre-spore specific promoter, PspoIIQ, and a delayed, more synchronous commitment to sporulation. We conclude that ComX mediated early commitment to sporulation of the wild type slows down biofilm formation and modulates the coexistence of multiple biological states during the early stages of biofilm development.
Influence of parental education on child mortality in Bangladesh: repeated cross-sectional surveys

ABSTRACT Reducing the mortality of children under-5 (U5) is an essential part of the Sustainable Development Goal (SDG). Although Bangladesh has made progress in reducing child mortality, there remain inequalities among different sociodemographic groups. Education is one particular key factor with a multidimensional impact on child health and survival. This study assessed the association between parental education and U5 mortality using repeated cross-sectional Bangladesh Demographic and Health Survey data. The risk of child death was substantially low among educated parents. Children of secondary or higher educated mother and father were about 30% (hazard ratio [HR] = 0.697, 95% confidence interval [CI] 0.596 to 0.815, p< .001) and 26% (HR = 0.738, 95% CI 0.635 to 0.858, p < .001), respectively, less likely to die early. Children from wealthier households and born to mothers with long birth spacings were less likely to face an early death. The study findings emphasize on imparting education to parents as an intervention strategy to continue the reduction of child mortality rate in Bangladesh, which could be a policy direction toward achieving the SDGs.

ABSTRACT In the United Kingdom (UK), women are more likely to live alone in later life. Social factors such as household composition have been shown to affect health and wellbeing as we age. The health and well-being of older women who live alone are of interest to researchers, care providers, health organizations, and policymakers. This article contributes to the literature by detailing a scoping review, establishing the current evidence in this field. The purpose and context of the review are given. The methodology and resulting data are described. Gaps in the literature and implications for practice and research are given.
COVID‐19 retinal microangiopathy as an in vivo biomarker of systemic vascular disease?

COVID‐19 is caused by SARS‐CoV‐2, a betacoronavirus that uses the angiotensin‐converting enzyme‐related carboxypeptidase (ACE2) receptor to gain entry into cells. ACE2 receptor is widely expressed in multiple organs, including the retina, an extension of the central nervous system. The ACE2 receptor is involved in the diabetic and hypertensive retinopathy. Additionally, coronaviruses cause ocular infections in animals, including retinitis, and optic neuritis.
Examination of Prognostic Factors Affecting Long-Term Survival of Patients with Stage 3/4 Gallbladder Cancer without Distant Metastasis

In advanced gallbladder cancer (GBC) radical resection, if multiple prognostic factors are present, the outcome may be poor; however, the details remain unclear. To investigate the poor prognostic factors affecting long-term surgical outcome, we examined 157 cases of resected stage 3/4 GBC without distant metastasis between 1985 and 2017. Poor prognostic factors for overall survival and treatment outcomes of a number of predictable preoperative poor prognostic factors were evaluated. The surgical mortality was 4.5%. In multivariate analysis, blood loss, poor histology, liver invasion, and ≥4 regional lymph node metastases (LNMs) were independent prognostic factors for poor surgical outcomes; invasion of the left margin or the entire area of the hepatoduodenal ligament and a Clavien–Dindo classification ≥3 were marginal factors. The analysis identified outcomes of patients with factors that could be predicted preoperatively, such as liver invasion ≥5 mm, invasion of the left margin or the entire area of the hepatoduodenal ligament, and ≥4 regional LNMs. Thus, the five-year overall survival was 54% for zero factors, 34% for one factor, and 4% for two factors (p < 0.05). A poor surgical outcome was likely when two or more factors were predicted preoperatively; therefore, new treatment strategies are required for such patients.
Probiotic Supplementation during the Perinatal and Infant Period: Effects on gut Dysbiosis and Disease

The perinatal period is crucial to the establishment of lifelong gut microbiota. The abundance and composition of microbiota can be altered by several factors such as preterm delivery, formula feeding, infections, antibiotic treatment, and lifestyle during pregnancy. Gut dysbiosis affects the development of innate and adaptive immune responses and resistance to pathogens, promoting atopic diseases, food sensitization, and infections such as necrotizing enterocolitis (NEC). Recent studies have indicated that the gut microbiota imbalance can be restored after a single or multi-strain probiotic supplementation, especially mixtures of Lactobacillus and Bifidobacterium strains. Following the systematic search methodology, the current review addresses the importance of probiotics as a preventive or therapeutic tool for dysbiosis produced during the perinatal and infant period. We also discuss the safety of the use of probiotics in pregnant women, preterm neonates, or infants for the treatment of atopic diseases and infections.
A Scoping Review of Literature About Mental Health and Well-Being Among Immigrant Communities in the United States

Immigration—both the experience of migrating and events after migration—can affect the mental health and well-being of immigrants and their communities. However, evidence suggests that immigrants in the United States do not access mental health services to the same extent as nonimmigrants. In particular, immigrant adolescents and young adults may have unique stressors related to their developmental stage, experiences in school and with peer groups, and shifting roles within family systems. This scoping review summarizes findings from published research studies and practitioner-focused gray literature about the mental health needs of immigrant communities in the United States. The review finds that specific mental health needs vary across factors like age, racial/ethnic group, immigration status, and place of residency. Findings also indicate that structural factors like immigration-related laws affect both access to mental health services and stressors in the overall environment for immigrants and their families. This review also explores models of community-level initiatives that utilize strengths-based approaches to promoting mental health and well-being among immigrant communities. Findings highlight the need for a better understanding of the mental health needs and current barriers to care among diverse immigrant populations, as immigration continues to play a major role in U.S. public policy and discourse. The COVID-19 pandemic taking place as this article goes to press in 2020 also raises questions regarding health equity and access for marginalized populations, including immigrants and their communities, and so these findings also indicate the need for further interdisciplinary research to assess intersections among the pandemic’s many impacts, including those related to mental health and well-being.
How Authenticity and Tradition Shift into Sustainability and Innovation: Evidence from Italian Agritourism

This study investigates the topic of innovation strategies based on tradition in the wake of sustainability, in the agritourism sector, as derived from the phenomenon of multifunctionality in agriculture. The results reveal that the tangible and intangible resources that originate from tradition are drivers for innovation. The research highlights how tradition, as grounded on diverse foundations, is able to generate novel products and services stemming from an innovative arrangement of past events, particularly the identity of a place, which brings out its authenticity and makes it even more attractive. In this paper, we delve into the multifaceted outcomes that tangible and intangible traditions have on the innovation and distinctive standing of this rising accommodation offer with regard to post-productivism agriculture, and how this is accomplished while also looking for sustainability. The sourced dataset is based on a qualitative investigation of 10 cases in the Salento area of Puglia, a region of southern Italy. Tradition-grounded strategies proved to have several viable routes leading to innovation and bear positive impacts on the territory and the creation of value, yielding significant results both for scholars and practitioners.
Effects of dietary protein on growth and body composition of Nile tilapia, Oreochromis niloticus L.

The effects of dietary protein (25%, 30%, 35%, 40% and 45%) on growth, survival, feed conversion ratio (FCR), protein efficiency ratio (PER) and body composition were investigated for four sizes (0.51, 45, 96 and 264 g) of Nile tilapia, Oreochromis niloticus L. In all four experiments, there was a progressive increase in growth with increasing dietary protein. In fry (0.51 g), significantly higher growth, survival and feed conversion were recorded for fish fed 40–45% rather than 25–35% protein diets. Similar trends for growth and FCR were also noted in 45 g fish. For larger (96 and 264 g) tilapia, significant differences in growth and FCR were found only between fish fed 25% and 30–45% protein diets. FCR and PER decreased with increasing weight of fish, and both were found to be negatively correlated with dietary protein level. Whole-body composition of the smallest fish was significantly influenced by dietary protein content. Percentage body protein of the fish fed 40–45% protein was higher than that of fish fed 25–35% protein diets, whereas lipid content decreased with increasing dietary protein level. In 45 g fish, both protein and lipid contents were higher in fish fed 25% and 30% protein diets than in those fed 35–45% protein diets. In larger tilapia, no significant influence of dietary protein level on body protein content was found. Percentage lipid decreased with increasing dietary protein level, and no definite trends in ash content were found. The results of these studies indicate that O. niloticus fry (0.51 g) should be reared on a practical diet containing 40% protein, and larger tilapia (96–264 g) on a diet containing 30% protein.
Self‐Powered Implantable Medical Devices: Photovoltaic Energy Harvesting Review

Implantable technologies are becoming more widespread for biomedical applications that include physical identification, health diagnosis, monitoring, recording, and treatment of human physiological traits. However, energy harvesting and power generation beneath the human tissue are still a major challenge. In this regard, self‐powered implantable devices that scavenge energy from the human body are attractive for long‐term monitoring of human physiological traits. Thanks to advancements in material science and nanotechnology, energy harvesting techniques that rely on piezoelectricity, thermoelectricity, biofuel, and radio frequency power transfer are emerging. However, all these techniques suffer from limitations that include low power output, bulky size, or low efficiency. Photovoltaic (PV) energy conversion is one of the most promising candidates for implantable applications due to their higher‐power conversion efficiencies and small footprint. Herein, the latest implantable energy harvesting technologies are surveyed. A comparison between the different state‐of‐the‐art power harvesting methods is also provided. Finally, recommendations are provided regarding the feasibility of PV cells as an in vivo energy harvester, with an emphasis on skin penetration, fabrication, encapsulation, durability, biocompatibility, and power management.
Optimizing a dual-frequency and phase modulation method for SSVEP-based BCIs

Objective. The design of the stimulation paradigm plays an important role in steady-state visual evoked potential (SSVEP)-based brain-computer interface (BCI) studies. Among various stimulation designs, the dual-frequency paradigm in which two frequencies are used to encode one target is of importance and interest. However, because the number of possible frequency combinations is huge, the existing dual-frequency modulation paradigms failed to optimize the encoding towards the best combinations. Thus, this work aiming at designing a new dual-frequency and phase modulation paradigm with the best combinations stimuli. Approach. This study proposed a dual-frequency and phase modulation method, which can achieve a large number of targets by making different combinations of two frequencies and an initial phase. This study also designed a set of methods for quickly optimizing the stimulation codes for the dual-frequency and phase modulation method. Main results. An online 40-class BCI experiment with 12 subjects obtained an accuracy of 96.06 ±4.00% and an averaged information transfer rate (ITR) of 196.09 ±15.25 bits min−1, which were much higher than the existing dual-frequency modulation paradigms. Moreover, an offline simulation with a public dataset showed that the optimization method was also effective for optimizing the single-frequency and phase modulation paradigm. Significance. These results demonstrate the high performance of the proposed dual-frequency and phase modulation method and the high efficiency of the optimization method for designing SSVEP stimulation paradigms. In addition, the coding efficiency of the optimized dual-frequency and phase modulation paradigm is higher than that of the single-frequency and phase modulation paradigm, and it is expected to further realize the BCI paradigm with a large amount of targets.
HDAC4 inhibition disrupts TET2 function in high-risk MDS and AML

Aberrant DNA methylation often silences transcription of tumor-suppressor genes and is considered a hallmark of myeloid neoplasms. Similarly, histone deacetylation represses transcription of genes responsible for cell differentiation/death. A previous clinical study suggested potential pharmacodynamic antagonism between histone deacetylase inhibitors (HDACi) and DNA hypomethylating agents (HMA). Herein, to determine such antagonism, we used MDS/AML lines and NHD13 transgenic mice, and demonstrated that treatment with the pan-HDACi suberoylanilide hydroxamic acid (SAHA) significantly decreased TET2 expression and global 5-hydroxymethylcytosine (5hmC) levels. Mechanistically, our RNAi screen revealed that HDAC4 was responsible for maintaining TET2 levels. Accordingly, HDAC4 knockout reduced expression levels of MTSS1, a known TET2 target, an event associated with decreased 5hmC enrichment on the MTSS1 enhancer. Retrospective analysis of GEO datasets demonstrated that lower HDAC4 levels predict worse prognosis for AML patients. In an MDS-L xenografted immunodeficient mouse model, vitamin C co-treatment prevented TET2 loss of activity seen following SAHA treatment. Accordingly, vitamin C co-treatment further reduced MDS-L cell engraftment relative to SAHA alone. In summary, our findings suggest that co-administration of a TET2 agonist with pan-HDACi treatment could effectively counter potential diminution in TET2 activity resulting from pan-HDACi treatment alone, providing a rationale for evaluating such combinations against high-risk MDS/AML.
Low dosages of vitamin A may cause a decrease in the total neuron number of fetal hippocampal rat cells.

OBJECTIVES We investigated the effect of low, medium and high doses of oral vitamin A, on the number of fetal hippocampal neurons. BACKGROUND High doses of vitamin A during pregnancy may cause embryonic malformations. There are reports about dosages that don't cause macroscopic malformations, but may cause mental and behavioral disorders. Still, quantitative morphological studies explaining this topic are lacking. METHODS We administered oral vitamin A to pregnant rats on the 10th-12th days of pregnancy at doses of 10000, 20000, 30000, 40000, 50000, 100000 and 200000 IU/kg. We collected the fetuses on the 19th day and removed their brains. After staining with cresyl violet and immunolabeling with Tunel and Ki67 antibody, we examined the hippocampi with stereological methods. RESULTS Vitamin A decreased hippocampal neuron numbers beginning from 20000 IU/kg. While the number of Ki67 positive cells increased with the dosage, the increase of apoptotic cells begun at the dose of 50000 IU/kg. CONCLUSION Our study demonstrates that vitamin A, beginning from the dosage of 20000 IU/kg, is decreasing the total hippocampal neuron numbers during the critical period of embryonic brain development and that apoptosis may not be the only factor in this outcome (Tab. 1, Fig. 3, Ref. 27).
