Anti‐ACSA‐2 defines a novel monoclonal antibody for prospective isolation of living neonatal and adult astrocytes

Astrocytes are the most abundant cell type of the central nervous system and cover a broad range of functionalities. We report here the generation of a novel monoclonal antibody, anti‐astrocyte cell surface antigen‐2 (Anti‐ACSA‐2). Flow cytometry, immunohistochemistry and immunocytochemistry revealed that Anti‐ACSA‐2 reacted specifically with a not yet identified glycosylated surface molecule of murine astrocytes at all developmental stages. It did not show any labeling of non‐astroglial cells such as neurons, oligodendrocytes, NG2+ cells, microglia, endothelial cells, leukocytes, or erythrocytes. Co‐labeling studies of GLAST and ACSA‐2 showed largely overlapping expression. However, there were also notable differences in protein expression levels and frequencies of single‐positive subpopulations of cells in some regions of the CNS such as cerebellum, most prominently at early postnatal stages. In the neurogenic niches, the dentate gyrus of the hippocampus and the subventricular zone (SVZ), again a general overlap with slight differences in expression levels were observed. ACSA‐2 was unlike GLAST not sensitive to papain‐based tissue dissociation and allowed for a highly effective, acute, specific, and prospective purification of viable astrocytes based on a new rapid sorting procedure using Anti‐ACSA‐2 directly coupled to superparamagnetic MicroBeads. In conclusion, ACSA‐2 appears to be a new surface marker for astrocytes, radial glia, neural stem cells and bipotent glial progenitor cells which opens up the possibility of further dissecting the characteristics of astroglial subpopulations and lineages.
Putting Sex Into Context in Later Life: Environmental Disorder and Sexual Interest Among Partnered Seniors

Background and Objectives This study examines whether neighborhood and household disorder is associated with sexual interest among partnered seniors. Research Design and Methods Analyses use dyadic data from Wave 2 of the National Social Life, Health, and Aging Project (NSHAP), a nationally representative sample of community-dwelling older adults (2010-2011). Measures of environmental disorder were conducted by trained interviewers. Survey data were also linked to census tract information from the 2009 American Community Survey. We used actor-partner interdependence models to estimate the likelihood of reporting low sexual interest. Results There was no observed association between neighborhood context (physical disorder or census tract socioeconomic disadvantage) and sexual interest, but husbands were more likely to report low sexual interest if they lived in more disorderly households. High marital quality protected against low sexual interest, but these evaluations did not mediate or moderate the putative effect of household disorder. Discussion and Implications Regardless of the broader neighborhood context, helping older adults maintain an orderly home space may help sustain sexual functioning. Future research should consider how various features of the environment matter for additional aspects of late-life sexuality.
THE EFFECTS OF THE AMBIENT LIQUID MEDIUM ON THE ABLATION EFFICIENCY, SIZE AND STABILITY OF SILVER NANOPARTICLES PREPARED BY PULSE LASER ABLATION IN LIQUID TECHNIQUE

Silver (Ag) nanoparticles (NPs) were synthesized by pulsed laser (Nd:YAG, 1064 nm) ablation of individual target in various solutions. The influence of deionized water (DIW), ethanol and Polyvinylpyrrolidone (PVP) as ambient medium on the fundamental aspects such as ablation efficiency, particle size and stability of Ag NPs was studied. UV-vis spectrophotometer and transmission electron microscopy (TEM) were used to study the optical characterization and morphological analysis of all the synthesized samples, respectively. Preparation in DIW was carried out as a reference sample. The experiments demonstrated that ablation efficiency and stability of NPs in ethanol medium are lowest than those prepared in PVP medium and the reference sample. PVP medium led to higher stability, lower ablation efficiency and finer average particle size compared to reference sample.
Proteomic analysis and genome annotation of Pichia pastoris, a recombinant protein expression host

Pichia pastoris is a widely used eukaryotic host for production of recombinant proteins. We performed a proteogenomic analysis using high resolution Fourier transform MS to characterize the proteome of the GS115 strain. Our analysis resulted in identification of 46 889 unique peptides mapping to 3914 unique protein groups, which corresponds to ∼80% of the predicted genes. In addition, our proteogenomic analysis led to the discovery of 64 novel genes and correction of 11 predicted gene models. The strategy used here demonstrates the utility of high resolution MS‐derived peptide sequence data to cover near complete proteomes of organisms. Given the popularity of P. pastoris as a protein expression host, this proteome map should provide a list of contaminants derived from the host to assist in optimization of heterologous protein production. All MS data have been deposited in the ProteomeXchange with identifier PXD000627 (http://proteomecentral.proteomexchange.org/dataset/PXD000627).
Does the Addition of Progressive Tension Sutures to Drains Reduce Seroma Incidence After Abdominoplasty? A Systematic Review and Meta-Analysis

Background Progressive tension sutures (PTS) are commonly utilized to reduce postoperative seroma in abdominoplasty. However, current evidence regarding PTS in abdominoplasty is limited to small series and the findings of single institutions. Objectives The authors reviewed the available literature concerning the effects of PTS and drains on seroma formation following abdominoplasty, and summarized the different techniques that have been described to date. Methods We conducted a systematic review of the Medline, Embase, and Cochrane databases. We identified randomized controlled trials (RCTs) and observational studies in which the numbers of patients who had postoperative seroma were indicated. We applied the Cochrane Collaboration's tool for assessing the risk of bias. Results Seven studies were included (three RCTs and four retrospective studies). Patients who had PTS and drains following abdominoplasty had a significantly lower rate of postoperative seroma than those who had drains only. The mean surgical time difference between the two groups was 23 minutes. There was no difference in postoperative seroma rate in patients who had PTS and drains placed following abdominoplasty compared to those who had PTS only. Conclusions Addition of PTS to drains reduces the risk of postoperative seroma in standard abdominoplasty. More RCTs with larger sample sizes and better comparability are warranted to confirm with more confidence the impact of PTS in abdominoplasty. Level of Evidence 2
Neutrosophic Soft Expert Sets

In this paper we introduce the concept of neutrosophic soft expert set (NSES). We also define its basic operations, namely complement, union, intersection, AND and OR, and study some of their properties. We give examples for these concepts. We give an application of this concept in a decision-making problem.
A new fun and robust version of an fMRI localizer for the frontotemporal language system

ABSTRACT A set of brain regions in the frontal, temporal, and parietal lobes supports high-level linguistic processing. These regions can be reliably identified in individual subjects using fMRI, by contrasting neural responses to meaningful and structured language stimuli vs. stimuli matched for low-level properties but lacking meaning and/or structure. We here present a novel version of a language ‘localizer,’ which should be suitable for diverse populations including children and/or clinical populations who may have difficulty with reading or cognitively demanding tasks. In particular, we contrast responses to auditorily presented excerpts from engaging interviews or stories, and acoustically degraded versions of these materials. This language localizer is appealing because it uses (a) naturalistic and engaging linguistic materials, (b) auditory presentation, (c) a passive listening task, and can be easily adapted to new stimulus materials enabling comparisons of language activation in children and speakers of diverse languages.
Effect of short‐ and long‐term feed restriction on ghrelin concentrations in turkeys1

ABSTRACT One‐day‐old broad‐breasted white turkeys (Meleagris gallopavo) were reared as recommended by industry standards. In Experiment 1, starting at 5 wk of age (WOA), birds were placed in individual cages with free access to feed and water. Blood samples were taken after 18 h of fasting (FASTING) and at 90 ± 5 min after feeding (1.5 h after feeding). In Experiment 2, birds were weighed, randomly assigned to 2 treatments, and placed in individual cages. In treatment 1 (n = 10), birds were fed ad libitum (FF), while birds in treatment 2 (n = 11) were placed on a restricted diet to allow for an average daily gain of 10.0 g per d from 4 to 11 WOA (RES). In Experiment 1, concentrations of ghrelin (P = 0.012) and glucose (P < 0.001) were increased 1.5 h after feeding compared with concentration during FASTING, whereas concentrations of adrenocorticotropic hormone (ACTH) (P < 0.001) and corticosterone (P = 0.002) were decreased 1.5 h after feeding. Concentration of insulin, free fatty acids, and ketone bodies followed a normal physiological response to fasting and feeding. Similarly, in Experiment 2, concentrations of ghrelin (P < 0.001) and glucose (P = 0.038) were increased in FF birds, whereas concentrations of corticosterone were decreased (P = 0.002) in FF birds. It could be concluded that in turkeys, preprandial (18 h of fasting) and long‐term feed restriction is associated with decreased concentration of ghrelin—thus, the opposite effect of that reported in chickens and mammalian species.
Dynamic variations in epithelial-to-mesenchymal transition (EMT), ATM, and SLFN11 govern response to PARP inhibitors and cisplatin in small cell lung cancer

Small cell lung cancer (SCLC) is one of the most aggressive forms of cancer, with a 5-year survival <7%. A major barrier to progress is the absence of predictive biomarkers for chemotherapy and novel targeted agents such as PARP inhibitors. Using a high-throughput, integrated proteomic, transcriptomic, and genomic analysis of SCLC patient-derived xenografts (PDXs) and profiled cell lines, we identified biomarkers of drug sensitivity and determined their prevalence in patient tumors. In contrast to breast and ovarian cancer, PARP inhibitor response was not associated with mutations in homologous recombination (HR) genes (e.g., BRCA1/2) or HRD scores. Instead, we found several proteomic markers that predicted PDX response, including high levels of SLFN11 and E-cadherin and low ATM. SLFN11 and E-cadherin were also significantly associated with in vitro sensitivity to cisplatin and topoisomerase1/2 inhibitors (all commonly used in SCLC). Treatment with cisplatin or PARP inhibitors downregulated SLFN11 and E-cadherin, possibly explaining the rapid development of therapeutic resistance in SCLC. Supporting their functional role, silencing SLFN11 reduced in vitro sensitivity and drug-induced DNA damage; whereas ATM knockdown or pharmacologic inhibition enhanced sensitivity. Notably, SCLC with mesenchymal phenotypes (i.e., loss of E-cadherin and high epithelial-to-mesenchymal transition (EMT) signature scores) displayed striking alterations in expression of miR200 family and key SCLC genes (e.g., NEUROD1, ASCL1, ALDH1A1, MYCL1). Thus, SLFN11, EMT, and ATM mediate therapeutic response in SCLC and warrant further clinical investigation as predictive biomarkers.
Genetic variation of long non-coding RNA TINCR contribute to the susceptibility and progression of colorectal cancer

Colorectal cancer (CRC) accounts for the leading causes of cancer-related morbidity and mortality. However, a large part of heritable factors are warranted to be explored. Long non-coding RNAs (lncRNAs) serve critical roles in cancer development and progression. Herein, we explored effect of genetic variants of Tissue differentiation-inducing non-protein coding RNA (TINCR), a key lncRNA required for somatic tissue differentiation and tumor progression, on risk and progression of CRC. Three tagSNPs, including rs2288947, rs8105637, and rs12610531, were evaluated in in a two-stage, case-control study. Two SNPs, rs2288947 and rs8105637, were significantly associated with susceptibility of CRC in both stages. When pooled together, the allele G was significantly associated with 23% decreased risk of CRC (OR=0.77; 95% CI=0.67-0.88; P value = 1.2×10−4)for SNP rs2288947. While for SNP rs8105637, the allele A was significantly associated with 22% increased risk of CRC (OR=1.22; 95% CI=1.09-1.37; P value = 6.2×10−4). The two SNPs were also statistically associated with occurrence of lymph node metastasis of CRC. The carriers of allele G are less likely to get lymph node metastasis (OR=0.77; 95% CI=0.63-0.94; P value = 0.011) for rs2288947, and the carriers of allele A are more likely to get lymph node metastasis (OR=1.22; 95% CI=1.03-1.43; P value = 0.019) for rs8105637. These results suggest that lncRNA TINCR polymorphisms may be implicated in the development and progression of CRC.
Thyroid Cancer Following Childhood Low-Dose Radiation Exposure: A Pooled Analysis of Nine Cohorts

Context: The increased use of diagnostic and therapeutic procedures that involve radiation raises concerns about radiation effects, particularly in children and the radiosensitive thyroid gland. Objectives: Evaluation of relative risk (RR) trends for thyroid radiation doses <0.2 gray (Gy); evidence of a threshold dose; and possible modifiers of the dose-response, e.g., sex, age at exposure, time since exposure. Design and Setting: Pooled data from nine cohort studies of childhood external radiation exposure and thyroid cancer with individualized dose estimates, ≥1000 irradiated subjects or ≥10 thyroid cancer cases, with data limited to individuals receiving doses <0.2 Gy. Participants: Cohorts included the following: childhood cancer survivors (n = 2); children treated for benign diseases (n = 6); and children who survived the atomic bombings in Japan (n = 1). There were 252 cases and 2,588,559 person-years in irradiated individuals and 142 cases and 1,865,957 person-years in nonirradiated individuals. Intervention: There were no interventions. Main Outcome Measure: Incident thyroid cancers. Results: For both <0.2 and <0.1 Gy, RRs increased with thyroid dose (P < 0.01), without significant departure from linearity (P = 0.77 and P = 0.66, respectively). Estimates of threshold dose ranged from 0.0 to 0.03 Gy, with an upper 95% confidence bound of 0.04 Gy. The increasing dose–response trend persisted >45 years after exposure, was greater at younger age at exposure and younger attained age, and was similar by sex and number of treatments. Conclusions: Our analyses reaffirmed linearity of the dose response as the most plausible relationship for “as low as reasonably achievable” assessments for pediatric low-dose radiation-associated thyroid cancer risk.
Logistic Regression Setup for RTB CTR Estimation

In this paper we investigate one of the most interesting problems of Big Data user feedback prediction which is the Real-Time Bidding Click-Through Rate estimation. We evaluate experimentally the impact of the widely-referenced methods for optimization of the logistic regression - the state-of-the art Real-Time Bidding optimization method - on the quality of CTR estimation. From the perspective of this impact, we evaluate different configurations of widely-referenced regularization techniques and compare them with a simple technique of the feature generalization. On the basis of the results of the extensive experimentation, we show that in the context of the application scenario investigated herein, an optimization of the stochastic gradient descent algorithm configuration may be successfully accompanied, or even replaced, by a simple feature generalization.
Detection of severe digital vasculopathy in systemic sclerosis by colour Doppler sonography is associated with digital ulcers

Objective Colour Doppler ultrasonography (CDUS) is very important in general vascular diagnostic procedures. Its role in determining the extent of vasculopathy in Systemic Sclerosis (SSc) needs further investigation. The aim of this study was to compare the presence of altered arteries with nailfold capillaroscopy and clinical signs of ischaemia, that is, digital ulcers or pitting scars (DU/PS). A feasible CDUS protocol is provided. Methods Two thousand five hundred and twenty-eight arteries of the fingers, palms and wrists from 79 SSc patients (32 arteries per patient) were examined using CDUS. Furthermore, nailfold capillaroscopy, clinical and laboratory data were evaluated. Results Narrowed or occluded lumens were seen in 39.8% of all assessable arteries (n = 2489) and 48.9% of all proper palmar digital arteries (n = 1564) but only 15.6% (P < 0.0001) of proximal arteries (n = 924). Fingerwise analyses presented significant coincidence of pathological CDUS findings and DU/PS (P = 0.0009). Pathological CDUS findings were also associated with elevated CRP concentrations, current or past smoking with ⩾20 pack-years, male gender and present or past DU/PS. Receiver operating characteristic curve analysis (area under the curve = 0.727) suggested a cut-off value of ⩾20% pathological vessels (sensitivity: 90.7%; specificity: 47.8%) for the presence of DU/PS. An examination protocol focusing on the right-hand digits II-V (proper palmar digital arteries) revealed similar results (area under the curve = 0.751; sensitivity: 93.0%; specificity: 43.5%). Conclusion CDUS of hand and finger arteries allows measurement of the extent of SSc vasculopathy, which is associated with clinical signs of chronic malperfusion. A shortened examination protocol of CDUS (right-hand digits II-V; 15 min instead of 45 min examination time) could complement vascular diagnostics in SSc.
Functional Evaluation of Transplanted Kidneys with Reduced Field-of-View Diffusion-Weighted Imaging at 3T

Objective To determine the feasibility of reduced field-of-view diffusion-weighted imaging (rFOV DWI) with multi-b values to detect functional variability in transplanted kidneys. Materials and Methods Using a 3T MRI scanner, multi-b rFOV DWI of transplanted kidney or native kidney was performed in 40 renal transplantation recipients and 18 healthy volunteers. The patients were stratified, according to an estimated glomerular filtration rate (eGFR): Group 1, eGFR ≥ 60 mL/min/1.73 m2; Group 2, eGFR ≥ 30 mL/min/1.73 m2 and < 60 mL/min/1.73 m2; Group 3, eGFR < 30 mL/min/1.73 m2. Total apparent diffusion coefficient (ADCT), perfusion-free ADC (ADCD) and perfusion fraction (FP) of kidneys were calculated and compared among the four groups. Correlations between the imaging results and eGFR were assessed. Results All volunteers had eGFR ≥ 60 mL/min/1.73 m2, while 16, 16, and 8 patients were included in Groups 1, 2, and 3, respectively. In the renal cortex, ADCT was higher in Group 1 ([1.65 ± 0.13] × 10−3 mm2/s) than Group 3 ([1.44 ± 0.11] × 10−3 mm2/s) (p < 0.05), and the inter-group differences of FP values were significant (all p < 0.05) (0.330 ± 0.024, 0.309 ± 0.019, 0.278 ± 0.033, and 0.250 ± 0.028 for control group, Groups 1, 2, and 3, respectively). Renal cortical ADCT, ADCD, FP, and renal medullary ADCT and FP correlated positively with eGFR (r = 0.596, 0.403, 0.711, 0.341, and 0.323, respectively; all p < 0.05). When using 0.278 as the cutoff value, renal cortical FP had a sensitivity of 97.1% and a specificity of 66.7% for predicting decreased renal function. Conclusion Multi-b rFOV DWI presents transplanted kidneys with high resolution, which is a promising functional tool for non-invasively monitoring function of transplanted kidneys.
Large-scale phylogenomic analysis resolves a backbone phylogeny in ferns

Abstract Background Ferns, originated about 360 million years ago, are the sister group of seed plants. Despite the remarkable progress in our understanding of fern phylogeny, with conflicting molecular evidence and different morphological interpretations, relationships among major fern lineages remain controversial. Results With the aim to obtain a robust fern phylogeny, we carried out a large-scale phylogenomic analysis using high-quality transcriptome sequencing data, which covered 69 fern species from 38 families and 11 orders. Both coalescent-based and concatenation-based methods were applied to both nucleotide and amino acid sequences in species tree estimation. The resulting topologies are largely congruent with each other, except for the placement of Angiopteris fokiensis, Cheiropleuria bicuspis, Diplaziopsis brunoniana, Matteuccia struthiopteris, Elaphoglossum mcclurei, and Tectaria subpedata. Conclusions Our result confirmed that Equisetales is sister to the rest of ferns, and Dennstaedtiaceae is sister to eupolypods. Moreover, our result strongly supported some relationships different from the current view of fern phylogeny, including that Marattiaceae may be sister to the monophyletic clade of Psilotaceae and Ophioglossaceae; that Gleicheniaceae and Hymenophyllaceae form a monophyletic clade sister to Dipteridaceae; and that Aspleniaceae is sister to the rest of the groups in eupolypods II. These results were interpreted with morphological traits, especially sporangia characters, and a new evolutionary route of sporangial annulus in ferns was suggested. This backbone phylogeny in ferns sets a foundation for further studies in biology and evolution in ferns, and therefore in plants.
Palmprint Identification Using an Ensemble of Sparse Representations

Among various palmprint identification methods proposed in the literature, sparse representation for classification (SRC) is very attractive offering high accuracy. Although SRC has good discriminative ability, its performance strongly depends on the quality of the training data. In particular, SRC suffers from two major problems: lack of training samples per class and large intra-class variations. In fact, palmprint images not only contain identity information but they also have other information, such as illumination and geometrical distortions due to the unconstrained conditions and the movement of the hand. In this case, the sparse representation assumption may not hold well in the original space since samples from different classes may be considered from the same class. This paper aims to enhance palmprint identification performance through SRC by proposing a simple yet efficient method based on an ensemble of sparse representations through an ensemble of discriminative dictionaries satisfying SRC assumption. The ensemble learning has the advantage to reduce the sensitivity due to the limited size of the training data and is performed based on random subspace sampling over 2D-PCA space while keeping the image inherent structure and information. In order to obtain discriminative dictionaries satisfying SRC assumption, a new space is learned by minimizing and maximizing the intra-class and inter-class variations using 2D-LDA. Extensive experiments are conducted on two publicly available palmprint data sets: multispectral and PolyU. Obtained results showed very promising results compared with both state-of-the-art holistic and coding methods. Besides these findings, we provide an empirical analysis of the parameters involved in the proposed technique to guide the neophyte.
