Urechis unicinctus is the only Echiurini species distributed in Bohai Gulf of China. The wild populations of this species have sharply declined in China due to overfishing. Over 150 samples from Bohai Gulf were collected in the present study, which were classified into five populations according to their geographic areas and body colors. The genetic diversity and population structure of these populations were investigated by mitochondiral COI and D-loop sequences. The haplotype diversity of U. unicinctus based on COI and D-loop sequences were still high. In addition, the evolution rate of D-loop region could faster than the COI gene of U. unicinctus. Meanwhile, over 99% genetic diversity was contributed by different individuals within populations. Moreover, phylogenetic trees did not show clear geographic or color cluster. Our findings indicated that this species in Bohai Gulf of China should be treated as a whole population.We have assembled and annotated the mitochondrial genome of Tinda javana (Macquart, 1838) (a species of soldier fly) in this study. It is 15,495 bp in length, including 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and a large non-coding control region (length 704 bp). The nucleotide composition of whole mitochondrial genome biases toward A and T (75.5%). Most PCGs use ATN as initiation codon, except for cox1 which starts with CGA. All PCGs end with common termination codon TAA/G. Phylogenetic analyses based on the nucleotide sequence data supported the monophyly of Stratiomyidae and the sister relationship between Pachygastrinae and the clade (Nemotelinae + (Hermetiinae + Sarginae)).

The cost of care is often reported as a primary reason why patients fail to seek dental treatment; however, this may not the only component.

To examine an underserved population's perspective on the importance of dental care and barriers they face to seek treatment. The effectiveness of compliance incentives, such as gift cards, was also examined.

We conducted a survey study to gain insight of an underserved population's perspective of barriers to care and correlated the reported barriers with the true reasons of missed appointments in our study cohort. Appointment compliance was also examined before and after implementation of gift card incentives, appoitment reminder letters and additional staff.

Most patients felt dental care was important/very important to them. However, no correlations were found between survey responses and true reasons for missing appointments. Eighty-seven percent of patients report having some form of financial difficulty and compliance statistically improved after implementaeported do not correlate with true reasons of appointment failure. Financial compensation was shown to improve compliance with appointments. Further information gathering is necessary to gain insight into true barriers to dental care within an underserved population.

A survey is a resource to identify reasons why patients abstain from seeking care but may be not the best one as reasons reported do not correlate with true reasons of appointment failure. Financial compensation was shown to improve compliance with appointments. Further information gathering is necessary to gain insight into true barriers to dental care within an underserved population.The zero-velocity update (ZUPT) algorithm provides valuable state information to maintain the inertial navigation system (INS) reliability when stationary conditions are satisfied. Employing ZUPT along with leveraging non-holonomic constraints can greatly benefit wheeled mobile robot dead-reckoning localization accuracy. However, determining how often they should be employed requires consideration to balance localization accuracy and traversal rate for planetary rovers. To address this, we investigate when to autonomously initiate stops to improve wheel-inertial odometry (WIO) localization performance with ZUPT. To do this, we propose a 3D dead-reckoning approach that predicts wheel slippage while the rover is in motion and forecasts the appropriate time to stop without changing any rover hardware or major rover operations. We validate with field tests that our approach is viable on different terrain types and achieves a 3D localization accuracy of ~97% over 650 m drives on rough terrain.Robotic systems frequently operate under changing dynamics, such as driving across varying terrain, encountering sensing and actuation faults, or navigating around humans with uncertain and changing intent. In order to operate effectively in these situations, robots must be capable of efficiently estimating these changes in order to adapt at the decision-making, planning, and control levels. Typical estimation approaches maintain a fixed set of candidate models at each time step; however, this can be computationally expensive if the number of models is large. In contrast, we propose a novel algorithm that employs an adaptive model set. We leverage the idea that the current model set must be expanded if its models no longer sufficiently explain the sensor measurements. By maintaining only a small subset of models at each time step, our algorithm improves on efficiency; at the same time, by choosing the appropriate models to keep, we avoid compromising on performance. We show that our algorithm exhibits higher efficiency in comparison to several baselines, when tested on simulated manipulation, driving, and human motion prediction tasks, as well as in hardware experiments on a 7 DOF manipulator.On December 31, 2019, the Wuhan Municipal Health Commission reported an increase in the incidence of pneumonia from an unknown cause. Shortly after, SARS-CoV-19 was identified as the responsible coronavirus for the heavy progress of the disease, which can manifest itself distinctively in different individuals. Coronavirus Disease 2019 (COVID-19) triggered a pandemic because of its high contagiousness before COVID-19 associated symptoms actually appear. In response to the rapid and continuous spread of the virus around the globe governments have mobilized their forces to restrict contact and thus avoid further infection and invested significant resources in treatment and prevention strategies to tackle COVID-19. As a result, US FDA and EMA have granted emergency use authorization for two mRNA-based vaccines, namely the vaccines developed by BioNTech/Pfizer and Moderna, for use in the USA and Europe. CCT251545 Due to the existing critical situation, the stages of vaccine development and testing have probably never been gone through so fast as at present. Here, we are briefly commenting on these two vaccines with their benefits, advantages and limitations.

People living with dementia in nursing homes have complex needs; impairments in cognition, communication, and daily function; neuropsychiatric symptoms (NPS); and poor quality of life (QoL). The current study examines impairments in non-verbal communication as a potential driver of NPS and QoL.

One hundred nursing home residents with dementia were assessed using the Emory Dyssemia Index (EDI), Neuropsychiatric Inventory Nursing Home version (NPI-NH), Quality of Life in Alzheimer's Disease (QoL-AD) at baseline, 12-, and 24-week follow-up.

The quantile regression (0.5) model indicated that impairment of non-verbal communication was independently associated with the severity of NPS (

=.001) and proxy reported QoL (

<.05), levels of agitation (

<.05), and professional caregiver burden (

<.05).

These results highlight a novel potential approach to improve NPS and QoL using retained elements of non-verbal communication, particularly for people with severe dementia.

Significant evidence suggests that the cholesterol-lowering statins can affect cognitive function and reduce the risk for Alzheimer's disease (AD) and dementia. These potential effects may be constrained by specific combinations of an individual's sex and apolipoprotein E (

) genotype.

Here we examine data from 252,327 UK Biobank participants, aged 55 or over, and compare the effects of statin use in males and females. We assessed difference in statin treatments taking a matched cohort approach, and identified key stratifiers using regression models and conditional inference trees. Using statistical modeling, we further evaluated the effect of statins on survival, cognitive decline over time, and on AD prevalence.

We identified that in the selected population, males were older, had a higher level of education, better cognitive scores, higher incidence of cardiovascular and metabolic diseases, and a higher rate of statin use. We observed that males and those participants with an

ε4-positive genotype f statin use, clarifying their specific interactions with treatments.

Palliative care focuses on reducing suffering and improving quality of life for individuals with serious illness and their families. In an effort to develop palliative care interventions for specialty memory care clinics, this study characterizes memory care providers' perspectives on addressing palliative care needs of people living with dementia (PLWD).

Qualitative interviews with specialty memory care providers were followed by thematic analysis by a multidisciplinary research team.

Provider approaches overlap with key domains of palliative care. Approaches unique to dementia include having a detailed understanding of dementia syndromes, behavioral symptoms, and caregiver burden. Challenges were identified related to disease progression, provider-level factors, and systems and cultural issues. Respondents identified training needed to strengthen a palliative care approach.

There are many strengths of using memory care teams to address palliative care needs of PLWD. However, they may require additional knowledge and training to strengthen their work.

We investigated the frequency, neuropathology, and phenotypic characteristics of spastic paraplegia (SP) that precedes dementia in presenilin 1 (

) related familial Alzheimer's disease (AD).

We performed whole exome sequencing (WES) in 60 probands with hereditary spastic paraplegia (HSP) phenotype that was negative for variants in known HSP-related genes. Where

mutation was identified, brain biopsy was performed. We investigated the link between HSP and AD with PSEN1 in silico pathway analysis and measured

the stability of PSEN1 mutant γ-secretase.

We identified a

variant (p.Thr291Pro) in an individual presenting with pure SP at 30 years of age. Three years later, SP was associated with severe, fast cognitive decline and amyloid deposition with diffuse cortical plaques on brain biopsy. Biochemical analysis of p.Thr291Pro

revealed that although the mutation does not alter active γ-secretase reconstitution, it destabilizes γ-secretase-amyloid precursor protein (APP)/amyloid beta (Aβn) interactions during proteolysis, enhancing the production of longer Aβ peptides.
