Effect of an Energy-Restricted, Nutritionally Complete, Higher Protein Meal Plan on Body Composition and Mobility in Older Adults With Obesity: A Randomized Controlled Trial.

BACKGROUND Increasing protein content of the diet might be an effective strategy to preserve muscle mass in older adults undergoing caloric restriction, thereby preserving muscle function. METHODS Ninety-six older adults (70.3 ± 3.7 years, 74% women, 27% African American) with obesity (35.4 ± 3.3 kg/m2; 47% total body fat) were randomized to a 6-month higher protein (providing 1.2-1.5 g/kg/d) weight loss (WL) program, utilizing the Medifast 4&2&1 Plan, or to weight stability (WS). Dual-energy x-ray absorptiometry-acquired total body mass and composition, and fast gait speed over 400 m was assessed at baseline, 3, and 6 months. RESULTS At baseline, dual-energy x-ray absorptiometry-acquired total body, fat, and lean masses were 95.9 ± 14.6, 44.6 ± 7.6, and 48.7 ± 9.5 kg, respectively, and 400-m gait speed was 1.17 ± 0.20 m/s. Total body mass was significantly reduced in the WL group (-8.17 [-9.56, -6.77] kg) compared with the WS group (-1.16 [-2.59, 0.27] kg), with 87% of total mass lost as fat (WL: -7.1 [-8.1, -6.1] kg; -15.9% change from baseline). A differential treatment effect was not observed for change in lean mass (WL: -0.81 [-1.40, -0.23] kg vs WS: -0.24 [-0.85, 0.36] kg). Four-hundred-meter gait speed was also unchanged from baseline although trends suggest slightly increased gait speed in the WL group [0.01 (-0.02, 0.04) m/s] compared with the WS group [-0.02 (-0.05, 0.01) m/s]. CONCLUSION Intentional weight loss using a high-protein diet is effective in producing significant total body mass and fat mass loss, while helping preserve lean body mass and mobility, in relatively high-functioning older adults with obesity.
Self-Discrepancy Theory as a Transdiagnostic Framework: A Meta-Analysis of Self-Discrepancy and Psychopathology

Self-discrepancy theory (SDT) is a model of the relations between the self and affect which has been applied to the study of different types of psychopathology including depression, anxiety, and eating disorders. Although the theory itself is compatible with a transdiagnostic perspective on psychopathology, to date no systematic review of the literature has examined that possibility. We conducted a meta-analysis that synthesized the literature on self-discrepancy and psychopathology across a heterogeneous range of 70 studies. Results showed a small-to-medium association between self-discrepancy and psychopathology that was highly robust and similar in magnitude across domains. Furthermore, self-discrepancy was related to higher levels of a range of negative emotions and lower levels of a range of positive emotions. Meta-regression models showed that the effects were greater for actual:ideal discrepancy compared with actual:ought discrepancy for both depression and anxiety, which was contrary to the tenets of SDT which suggests specific associations between actual:ideal discrepancy and depression and actual:ought discrepancy and anxiety. Measurement type (i.e., idiographic vs. nomothetic) was a significant predictor of the effects for depression and anxiety, such that nomothetic measures evidenced greater associations compared with idiographic measures. Our findings could suggest that self-discrepancy represents a contributory factor related to a number of psychiatric disorders. However, the tenet of SDT suggesting unique associations between actual:ideal and actual:ought discrepancy and anxiety and depression respectively was not supported. Implications are discussed for future research on self-discrepancy and psychopathology including the study of mechanistic frameworks.
“We should see her like part of the team”: an investigation into care home staff’s experiences of being part of an RCT of a complex psychosocial intervention

Abstract Objectives: To contribute to improvements in the design and delivery of intervention research in care homes by adopting a collaborative approach that listens to the experiences of care home staff who had participated in a clinical trial aimed at optimising and evaluating a psychosocial intervention package for people with dementia. Methods: Qualitative study involving focus group discussions (FGDs) involving 41 staff across 6 care homes with the UK. Inductive thematic analysis was used to identify themes and interpret the data. Results: Three overarching themes emerged as influential: Recognising preparedness; working together and learning more than expected. The findings highlighted the need to be attentive in addressing staff expectations, the value of sustained relationships and recognition of good practice. The FGDs also identified areas of unanticipated learning that staff and managers adopted. Conclusions: The FGDs showed the importance of considering the overall experience of care home staff who are involved in research and the importance of valuing the skills and experience they hold through positive affirmation. There are often unanticipated consequences of research involvement both on staff practice and on relationships which if promoted could help sustain effective ways of working together.
Coverage rate of ADME genes from commercial sequencing arrays

Abstract Pharmacogenomics offers remarkable potential for the rapid translation of discoveries into changes in clinical practice. In the present work, we are interested in evaluating the ability of commercially available genome-wide association sequencing chips to cover genes that have high pharmacogenomics potential. We used a set of 2794 variations within 369 absorption, distribution, metabolism, and elimination (ADME) genes of interest, as previously defined in collaboration with the Pharma ADME consortium. We have compared the Illumina TrueSeq and both Agilent SureSelect and HaloPlex sequencing technologies. We have developed Python scripts to evaluate the coverage for each of these products. In particular, we considered a specific list of 155 allelic variants in 34 genes which present high pharmacogenomics potential. Both the theoretical and practical coverage was assessed. Given the need to have a good coverage to establish confidently the functionality of an enzyme, the observed rates are unlikely to provide sufficient evidence for pharmacogenomics studies. We assessed the coverage using enrichment technology for exome sequencing using the Illumina Trueseq exome, Agilent SureSelectXT1 V4 and V5, and Haloplex exome, which offer a coverage of 96.12%, 91.61%, and 88.38%, respectively. Although pharmacogenomic advances had been limited in the past due in part to the lack of coverage of commercial genotyping chips, it is anticipated that future studies that make use of new sequencing technologies should offer a greater potential for discovery.
Bipolar Disorder and Comorbid Borderline Personality Disorder: Patient Characteristics and Outcomes in US Hospitals

Background and objectives: The quality of life and disease outcomes in bipolar patients, including increased risk of psychiatric hospitalizations and suicide, are adversely affected by the presence of borderline personality disorder (BPD). Our study aims to determine the impact of BPD on the inpatient outcomes of bipolar disorder patients. Methods: We used Nationwide Inpatient Sample from the US hospitals and identified cases with bipolar disorder and comorbid BPD (N = 268,232) and controls with bipolar disorder only (N = 242,379), using the International Classification of Diseases, 9th Revision, and Clinical Modification codes. We used multinomial logistic regression to generate odds ratios (OR) and evaluate inpatient outcomes. Results: The majority of the bipolar patients with BPD were female (84.2%), Caucasian (83.1%) and 18–35 years age (53.9%). Significantly longer inpatient stays, higher inpatient charges, and higher prevalence of drug abuse were noted in bipolar patients with BPD. The suicide risk was higher in bipolar patients with BPD (OR = 1.418; 95% CI 1.384–1.454; p < 0.001). In addition, utilization of electroconvulsive treatment (ECT) was higher in bipolar patients with comorbid BPD (OR = 1.442; 95% CI 1.373–1.515; p < 0.001). Conclusions: The presence of comorbid BPD in bipolar disorder is associated with higher acute inpatient care due to a longer inpatient stay and higher cost during hospitalization, and higher suicide risk, and utilization of ECT. Further studies in the inpatient setting are warranted to develop effective clinical strategies for optimal outcomes and reduction of suicide risk in bipolar patients with BPD.
LEF-1 drives aberrant β-catenin nuclear localization in myeloid leukemia cells

Canonical Wnt/β-catenin signaling is frequently dysregulated in myeloid leukemias and is implicated in leukemogenesis. Nuclear-localized β-catenin is indicative of active Wnt signaling and is frequently observed in acute myeloid leukemia (AML) patients; however, some patients exhibit little or no nuclear β-catenin even where cytosolic β-catenin is abundant. Control of the subcellular localization of β-catenin therefore represents an additional mechanism regulating Wnt signaling in hematopoietic cells. To investigate the factors mediating the nuclear-localization of β-catenin, we carried out the first nuclear/cytoplasmic proteomic analysis of the β-catenin interactome in myeloid leukemia cells and identified putative novel β-catenin interactors. Comparison of interacting factors between Wnt-responsive cells (high nuclear β-catenin) versus Wnt-unresponsive cells (low nuclear β-catenin) suggested the transcriptional partner, LEF-1, could direct the nuclear-localization of β-catenin. The relative levels of nuclear LEF-1 and β-catenin were tightly correlated in both cell lines and in primary AML blasts. Furthermore, LEF-1 knockdown perturbed β-catenin nuclear-localization and transcriptional activation in Wnt-responsive cells. Conversely, LEF-1 overexpression was able to promote both nuclear-localization and β-catenin-dependent transcriptional responses in previously Wnt-unresponsive cells. This is the first β-catenin interactome study in hematopoietic cells and reveals LEF-1 as a mediator of nuclear β- catenin level in human myeloid leukemia.
"Automatic vehicle classi¿cation using appearance based features"

Vehicle classification has been a highly focused topic amongst the scientific community due to its application in automatic tolling systems, road surveillance, traffic monitoring, etc. Image-based classification using computer vision techniques provides a non-invasive, cost effective, automated option to these systems. In traffic video surveillance systems vehicle detection and classification help provide more accurate and detailed statistics that can be used in intelligent transport systems. We implemented a non-invasive vision based vehicle classification system able to operate in both multilane free flow environments and in toll stations. Additionally, it can be used in surveillance cameras present in various motorways to provide not only quantitative information about flowing traffic but also qualitative. In this work we implement three hog-based descriptors as well as an additional edge points groups SIFT-based descriptor. These were tested on four distinct datasets captured using cameras already present in tolling/surveillance locations in various motorways. We were able to obtain an average of 97% accuracy using a global HOG descriptor. Using multiple SVM trained with local HOG descriptors we slightly improved results when high quality images were used, but more importantly showed the potential application of this method when well localized highly descriminatory sections of an object exist. Additionally we showed that the HOG-based descriptors classification was able to outperform the SIFT-based edge points groups across all datasets.
Biosynthesis of O-N-acetylgalactosamine glycans in the human cell nucleus

Biological functions of nuclear proteins are regulated by post-translational modifications (PTMs) that modulate gene expression and cellular physiology. However, the role of O-linked glycosylation (O-GalNAc) as a PTM of nuclear proteins in the human cell has not been previously reported. Here, we examined in detail the initiation of O-GalNAc glycan biosynthesis, representing a novel PTM of nuclear proteins in the nucleus of human cells, with an emphasis on HeLa cells. Using soluble nuclear fractions from purified nuclei, enzymatic assays, fluorescence microscopy, affinity chromatography, MS, and FRET analyses, we identified all factors required for biosynthesis of O-GalNAc glycans in nuclei: the donor substrate (UDP-GalNAc), nuclear polypeptide GalNAc -transferase activity, and a GalNAc transferase (polypeptide GalNAc-T3). Moreover, we identified O-GalNAc glycosylated proteins in the nucleus and present solid evidence for O-GalNAc glycan synthesis in this organelle. The demonstration of O-GalNAc glycosylation of nuclear proteins in mammalian cells reported here has important implications for cell and chemical biology.
Building resilience: a mental health intervention for Tanzanian youth living with HIV

ABSTRACT Despite a growing population of youth living with HIV, few interventions have been developed to address their unique mental health needs and to promote resilience. Based on our prior needs assessment, a mental health intervention, Sauti ya Vijana ( The Voice of Youth), was developed to address identified mental health needs and promote resilience. The intervention emphasized resilience strategies for identifying and coping with stressful events, supporting strong familial and social relationships, and planning for a safe and healthy living environment through stigma reduction, planning for disclosure, and instilling hope for the future. Ten group sessions (two of which were joint youth/caregiver sessions) and two individual sessions were developed around these three resilience domains. Youth living with HIV (average age 17.4 years), who were receiving antiretroviral therapy and attending HIV adolescent clinic in Tanzania were randomized to intervention or treatment as usual. Trained group leaders led the intervention sessions. Near perfect program fidelity by the group leaders and unanimous acceptance of the intervention by the youth was documented. SYV successfully promoted youth resilience as measured by youth-reported utilization of new coping skills, improved peer and caregiver relationships, reduced stigma, and improved confidence to live positively according to their personal values.
Next generation designer virus-like particle vaccines for dengue

ABSTRACT Introduction: A safe and efficacious vaccine for dengue continues to be an unmet public health need. The recent licensing of a dengue vaccine (Dengvaxia) developed by Sanofi has brought to the fore the safety issue of vaccine-induced infection enhancement. Areas covered: This article focuses on two new yeast-produced tetravalent dengue envelope domain III-displaying virus-like particulate vaccine candidates reported in early 2018 and reviews the rationale underlying their design, and pre-clinical data which suggest that these may offer promising alternate options. Expert commentary: These are the only vaccine candidates so far to have demonstrated the induction of primarily serotype-specific neutralizing antibodies to all dengue virus serotypes in experimental animals. Interestingly, these antibodies lack infection-enhancing potential when evaluated using the AG129 mouse model.
Evaluation of a microbial muramidase supplementation on growth performance, apparent ileal digestibility, and intestinal histology of broiler chickens

ABSTRACT The current study evaluated the effects of different inclusion levels of microbial muramidase (Muramidase 007, DSM Nutritional Products) on gastrointestinal functionality by determination of apparent ileal digestibility (AID) of nutrients, investigation of intestinal histomorphology, and quantification of resulting growth performance. Four maize‐wheat‐soybean experimental diets were produced without (C) and with different dosages of muramidase: low (L, 25,000 LSU(F)/kg), medium (M, 35,000 LSU(F)/kg), and high (H, 45,000 LSU(F)/kg); diets were fed to broilers for 35 d. At the end of the experiment, AID of ether extract (EE), crude protein (CP), Ca, and P were determined and samples of the mid‐jejunum and ‐ileum were collected for histomorphological observations. Data were subjected to ANOVA analysis using the GLM procedure. Orthogonal polynomial contrasts were used to assess linear and quadratic effects of different levels of the muramidase. At the end of the trial, Muramidase 007 supplementation linearly increased body weight gain and decreased feed conversion ratio (FCR) (P ≤ 0.05). Adding the muramidase to broiler diets also linearly increased the European poultry efficiency factor (P ≤ 0.05). Inclusion of the muramidase in broiler diets linearly increased AID of CP, EE, and P (P ≤ 0.05), and the H group had a higher AID of EE and CP compared to C group (P ≤ 0.05). Microbial muramidase supplementation linearly increased ileal villus length to crypt depth ratio and decreased the number of ileal CD45 cells (P ≤ 0.05). Broilers fed M and H diets had fewer number of CD45 cells in the ileum compared to those in C group (P ≤ 0.05). In conclusion, the results of the present study demonstrated that inclusion of the microbial muramidase in broiler diets could increase AID of key nutrients and improve growth performance in broilers. Adding microbial muramidase to broiler diets can therefore be considered as an interesting prospect to improve gastrointestinal functionality. Biological mechanisms causing these improvements need to be studied further.
Detection algorithm based on block mode and codebook model

In order to solve the problem on detecting moving objects with the complex background captured using a static camera,and at the same time,to overcome the shortage of detection speed and the accuracy in the detection of moving objects currently,we presented a real-time algorithm for the moving object detection with an improved codebook model.First,we divided an image into several blocks(MacroBlock) by using the idea of block.Then,for each macroblock,a codebook was built.During the moving object detection,we used the same way to divide the current frame into several blocks,just achieving each macroblock's pixel-means and brightness-means to compare with the codebook to identify whether it was foreground block or not.The experiment proves that this algorithm not only can restrain the fake target effectively but can also achieve robust and fast detection in videos which contain moving background.
Activating metabotropic glutamate receptor-7 attenuates visceral hypersensitivity in neonatal maternally separated rats

Increasing evidence has indicated that metabotropic glutamate receptor-7 (mGluR7) is an important target for reducing anxiety and stress-associated behaviours. Notably, mood disorders exhibit high levels of comorbidity with gastrointestinal dysfunction; however, the role of mGluR7 outside of the central nervous system is currently unknown. Activating mGluR7 likely increases colonic secretory function. Therefore, the present study aimed to evaluate the possible effects of mGluR7 on the visceral hypersensitivity of irritable bowel syndrome (IBS) in rats. The expression levels of mGluR7 were assessed in the colon tissues of rats with neonatal maternal separation (NMS)-induced visceral hypersensitivity using reverse transcription-quantitative polymerase chain reaction, western blotting and immunohistochemistry. In addition, the mGluR7 agonist AMN082 (3 or 10 mg/kg; i.p.) was administered 1 h prior to the visceral hypersensitivity test, and the effects of AMN082 were then observed on the nuclear factor (NF)-κB signalling pathway. The mRNA and protein expression levels of mGluR7 were upregulated in the colon mucosa of NMS rats compared with in normal control rats. Notably, administration of AMN082 (10 mg/kg) attenuated colorectal distension (CRD)-induced visceral hypersensitivity in NMS rats. In addition, interleukin-10 and transforming growth factor-β mRNA expression levels were upregulated, whereas interferon-γ mRNA expression levels were downregulated in the NMS + AMN082 group compared with in NMS rats. The number of cluster of differentiation 3+ T cells in the intestinal mucosa and myeloperoxidase activity were decreased in NMS + AMN082 rats. Furthermore, AMN082 treatment reduced the protein expression levels of phosphorylated-NF-κB in the colon tissue of NMS rats. These results indicated that activation of mGluR7 may attenuate CRD-induced visceral hypersensitivity in experimental IBS and reduce the abnormal immune cytokine response. In addition, it was suggested that the role of AMN082 in modulating the inflammatory response may be partially associated with inhibiting NF-κB activation. These data suggested that targeting mGluR7 may be useful in the treatment of stress-associated IBS.
Informativeness of dental morphology in ancestry estimation in African Americans.

OBJECTIVES Our objective is to assess the informativeness of dental morphology in estimating biogeographic ancestry in African Americans. MATERIALS AND METHODS The data are 62 dental morphological traits scored as nondichotomized and dichotomized in 797 individuals, 992,601 SNPs from 271 individuals, and 645 STRs from 177 individuals. Each dataset consists of Africans, Europeans, and African Americans. For each dataset, we summed Fisher Information (FI), then used STRUCTURE to estimate ancestry. RESULTS Total FI was highest for SNPs, followed by STRs, nondichotomized dental traits, and dichotomized dental traits. For both genetic datasets, Africans and Europeans fell into two distinctive clusters with low 90% credible regions for individual ancestry estimates. In African Americans, membership in the African cluster was 76.4% and 80.4% for SNPs and STRs, respectively. For the dental data, all Africans and Europeans had appreciable membership in both clusters and comparatively high 90% credible regions for individual ancestry estimates. Nonetheless, African Americans had consistently higher membership in the same cluster in which Africans had high membership. African American membership in this cluster was significantly higher for the nondichotomized form than for the dichotomized. DISCUSSION AND CONCLUSIONS FI potentially provides a useful gauge of the effectiveness of dental and genetic data for ancestry estimation. The comparatively high FI of nondichotomized dental traits suggests data in this form may be better suited for studies of admixture than dichotomized data. Because of high error in individual ancestry estimates, dental morphological data may be unable to distinguish differences in ancestry among individuals within admixed populations.
