#1
Sarah E Gilman
Predicting the effects of climate change on species and communities remains a pre-eminent challenge for biologists. Critical among this is understanding the indirect effects of climate change, which arise when the direct, physiological effects of climate on one species change the outcome of its interaction with a second species, altering the success of the second species. A diverse array of approaches to predicting indirect effects exists from mechanistic models, which attempt to build-up from physiological changes to ecological consequences, to ecological models that focus solely on the ecological scale...

Voltage-gated sodium channels (VGSCs) in peripheral nociceptive sensory neurons are critical to transmit pain signals. BmK I purified from the venom of scorpion Buthus martensi Karsch (BmK) has been demonstrated to be the primary contributor of envenomation-associated pain. However, the role of distinct VGSCs such as Nav1.6 in the induction and maintenance of pain behaviors induced by BmK I was ambiguous. Herein, using molecular and behavioral approaches we investigated the mRNA and protein expression profiles of Nav1...

Background: Nudging refers to interventions that organize the choice architecture in order to alter people's behaviour in a predictable way without forbidding any options or significantly changing their economic incentives. As a strategy to encourage healthy behaviour, nudging can serve as a complement to health education. However, the empirical evidence regarding the effectiveness of nudging as a way to influence food choice remains contradictory. To address this issue, a systematic review and meta-analysis was conducted to test the effects of nudging to encourage people to select more fruit and vegetables...

Background: Osteopetrosis encompasses a group of rare metabolic bone diseases characterized by impaired osteoclast activity or development, resulting in high bone mineral density. Existing guidelines focus on treatment of the severe infantile forms with hematopoietic cell transplantation (HCT), but do not address the management of patients with less severe forms for whom HCT is not the standard of care. Therefore, our objective was to develop expert consensus guidelines that would address the management of these patients...

Motivation: Studying transcript regulatory patterns in cell differentiation is critical in understanding its complex nature of the formation and function of different cell types. This is done usually by measuring gene expression at different stages of the cell differentiation. However, if the gene expression data available are only from the mature cells, we have some challenges in identifying transcript regulatory patterns that govern the cell differentiation. Results: We propose to exploit the information of the lineage of cell differentiation in terms of correlation structure between cell types...

Objective: Cognitive functions have been largely investigated in multiple sclerosis. Less attention has been paid to social communication abilities, despite their presumptive affect on quality of life. We run the first comprehensive assessment of pragmatic skills in multiple sclerosis, evaluating also the relationship between pragmatics and other cognitive domains. Methods: Forty-two multiple sclerosis patients and 42 controls were tested for pragmatic abilities, neuro-cognition, social cognition, depression, and fatigue...

Sleep problems relate to brain changes in aging and disease, but the mechanisms are unknown. Studies suggest a relationship between β-amyloid (Aβ) accumulation and sleep, which is likely augmented by interactions with multiple variables. Here, we tested how different cerebrospinal fluid (CSF) biomarkers for brain pathophysiology, brain atrophy, memory function, and depressive symptoms predicted self-reported sleep patterns in 91 cognitively healthy older adults over a 3-year period. The results showed that CSF levels of total- and phosphorylated (P) tau, and YKL-40-a marker of neuroinflammation/astroglial activation-predicted poor sleep in Aβ positive older adults...

Aims: Non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly used as thromboembolic prophylaxis in cardioversion. We examined the waiting time to cardioversion and the outcomes in patients with non-valvular atrial fibrillation (AF) of > 48 h of duration who were treated with either NOACs or warfarin. Methods and results: Anticoagulation was handled in a structured, multidisciplinary AF-clinic. The objectives were the waiting time to cardioversion, and thromboembolism and major bleeding events within 60 days...

Motivation: Learning the joint distributions of measurements, and in particular identification of an appropriate low-dimensional manifold, has been found to be a powerful ingredient of deep leaning approaches. Yet, such approaches have hardly been applied to single nucleotide polymorphism (SNP) data, probably due to the high number of features typically exceeding the number of studied individuals. Results: After a brief overview of how deep Boltzmann machines (DBMs), a deep learning approach, can be adapted to SNP data in principle, we specifically present a way to alleviate the dimensionality problem by partitioned learning...

PURPOSE: To determine whether thrombospondin-1 might be used as a prognostic factor in ovarian cancer patients. METHOD: Ninety-six female subjects hospitalized in years 2011-2014 was included in the study. Transvaginal ultrasound examination was performed in all patients. In 39 cases of suspected ovarian cancer, CT scans were also performed. Each patient had been subjected to collection of a 5-mL blood sample before the laparoscopic procedure. Thrombospondin-1 concentrations were quantified in serum by multiplex fluorescent bead-based immunoassays (Luminex) at the Laboratory of the Department of General Pathology...

OBJECTIVE: To evaluate the reliability and validity of an adapted Korean version of the Spinal Appearance Questionnaire (SAQ). METHODS: Translation/retranslation of the English version of the SAQ was conducted, and all steps of the cross-cultural adaptation process were performed. The Korean version of the SAQ (K-SAQ) and the previously validated appearance domain of the Korean version of the Scoliosis Research Society-22 Outcomes questionnaire (K-SRS-22) were mailed to 160 patients with adolescent idiopathic scoliosis (AIS)...

Primary neuroendocrine carcinoma of the breast (NECB) is a rare malignant tumor with controversial biological behavior and a lack of data guiding treatment decisions due to its scarcity. Cancer gene-expression profiling tests provide a better indication of clinical prognosis and help determine the best clinical management versus the traditional clinical and pathological parameters. This is a report of a NECB with a genetic assay that showed a low-risk tumor despite high-grade and poorly differentiated histopathological features...

Here we link plant source phylogeny to its chemical characteristics and determine parameters useful for predicting DOM phytotoxicity towards algal monocultures. We found that DOM characterised using UV-visible spectroscopic indices and elemental analysis is useful for distinguishing DOM plant sources. Specifically, combined values of absorbance at 440 nm and coefficients for the spectral slope ratio, were used to distinguish between gymnosperm-leached DOM and that from angiosperms. In our bioassays, DOM leached from 4 g leaf L(-1) resulted in over 40% inhibition of photosynthetic yield for the cyanobacterium, Cylindrospermopsis raciborskii, for eight of the nine plants tested...

Methods: A total of 258 un-splenectomize HS patients were consecutively enrolled. Correlation of hemoglobin concentration, hemolytic parameters, compensating erythropoiesis and the EMA binding test were evaluated. Results: 258 (128 male and 130 female) patients were included in this study, including 91 compensatory hemolysis patients, 53 patients with mild anemia, 78 patients with moderate anemia and 36 patients with severe anemia...

Objective: To explore an optimal method for granulocyte cell production from umbilical cord blood mononuclear cells. Methods: Erythrocytes were precipitated by hydroxyethyl starch. Mononuclear cells were isolated through Ficoll density gradient centrifugation. Different media, additives and cultivation model were chosen for granulocyte induction. Cell morphology was observed by microscopy, and cell phenotype was detected by flow cytometry. The CD18 expression of granulocytes was tested by immunofluorescence assay, and phagocytosis test was executed as well...
