#1
Xiao-Tong Yuan, Qingshan Liu
We introduce a family of Newton-type greedy selection methods for ℓ0-constrained minimization problems. The basic idea is to construct a quadratic function to approximate the original objective function around the current iterate and solve the constructed quadratic program over the cardinality constraint. The next iterate is then estimated via a line search operation between the current iterate and the solution of the sparse quadratic program. This iterative procedure can be interpreted as an extension of the constrained Newton methods from convex minimization to non-convex ℓ0-constrained minimization...

Arthritis and depression are two of the top disabling conditions. When arthritis and depression exist in the same individual, they can interact with each other negatively and pose a significant healthcare burden on the patients, their families, payers, healthcare systems, and society as a whole. Areas covered: The primary objective of this review is to summarize, identify knowledge gaps and discuss the challenges in estimating the healthcare burden of depression among individuals with arthritis. Electronic literature searches were performed on PubMed, Embase, EBSCOhost, Scopus, the Cochrane Library, and Google Scholar to identify relevant studies...

A heterozygous germline variant in the HABP2 gene c.1601G > A (p.Gly534Glu), which negatively impacts its tumor suppressive activity in vitro, has been described in 4-14% of kindreds of European-American ancestry with familial papillary thyroid carcinoma (fPTC). But it is also found in ≈4% of Europeans and European/Americans from public databases that, however, did not provide information on the thyroid function of the controls. To get unbiased results, we decided to compare HABP2 genotypes of patients with fPTC with those of "thyroid-checked" controls...

BACKGROUND: Quality of life (QoL) is an important outcome for people with dementia living in care homes but usually needs to be rated by a proxy. We do not know if relative or paid carer proxy reports differ. We conducted the first systematic review and meta-analysis of data investigating whether and how these proxy reports of QoL differ. METHODS: We searched four databases: Medline, Embase, PsychInfo, and CINAHL in October 2015 with the terms: dementia, QoL, proxy, and care home...

Over the past six years we have been studying extracts from tropical, specially Amazon, plants, to search for new sensitizers for photodynamic therapy of cancer and infectious diseases. Tectona grandis is a genus of tropical hardwood trees in the mint family, Lamiaceae. That is native to south and southeast Asia, but since the end of the 20th century is also gaining ground in the Amazon. The present work aims to evaluate the photodynamic potential of hydro-alcoholic extract from Tectona grandis LF leaves (TGE) and the same extract prepared as the oil-water nanoemulsion (TGE-NE) against melanoma B16 F10 cells...

BACKGROUND AND AIMS: The Nictaba family groups all proteins that show homology to Nictaba, the tobacco lectin. So far, Nictaba and an Arabidopsis thaliana homologue have been shown to be implicated in the plant stress response. The availability of more than 50 sequenced plant genomes provided the opportunity for a genome-wide identification of Nictaba-like genes in 15 species, representing members of the Fabaceae, Poaceae, Solanaceae, Musaceae, Arecaceae, Malvaceae and Rubiaceae. Additionally, phylogenetic relationships between the different species were explored...

Deep learning (DL) is a family of machine learning methods that has gained considerable attention in the scientific community, breaking benchmark records in areas such as speech and visual recognition. DL differs from conventional machine learning methods by virtue of its ability to learn the optimal representation from the raw data through consecutive nonlinear transformations, achieving increasingly higher levels of abstraction and complexity. Given its ability to detect abstract and complex patterns, DL has been applied in neuroimaging studies of psychiatric and neurological disorders, which are characterised by subtle and diffuse alterations...

BACKGROUND: Schizophrenia is a highly heterogeneous disorder, and around a third of patients are treatment-resistant. The only evidence-based treatment for these patients is clozapine, an atypical antipsychotic with relatively weak dopamine antagonism. It is plausible that varying degrees of response to antipsychotics reflect categorically distinct illness subtypes, which would have significant implications for research and clinical practice. If these subtypes could be distinguished at illness onset, this could represent a first step towards personalised medicine in psychiatry...

Fungal immunomodulatory protein (FIP)-sch2, an immunomodulatory protein identified in the ascomycete Stachybotrys chlorohalonata by a sequence similarity search, is a novel member of the FIP family. FIP-sch2 shares high sequence identity, structure, and evolutionary conservation with previously reported FIPs. It was satisfactorily expressed in Escherichia coli with a glutathione S-transferase (GST) tag and purified by GST-affinity magnetic beads. To characterize the direct antitumor effects, human lung adenocarcinoma A549 cells were treated with different concentrations of recombinant FIP (rFIP)-sch2 in vitro, and the results showed that rFIP-sch2 could reduce cell viability dose-dependently with a half-maximal inhibitory concentration (IC50) of 9...

Dinoflagellates are unicellular eukaryotes capable of forming spectacular harmful algal blooms (HABs). Eutrophication of coastal waters by fertilizer runoff, nitrate in particular, has contributed to recent increases in the frequency, magnitude and geographic extent of HABs. Although physiological nitrate uptake and assimilation in dinoflagellates have often been measured in the field and in the laboratory, no molecular components involved in nitrate transport have yet been reported. This study reports the first identification and characterization of dinoflagellate nitrate transporters, found in the transcriptome of the bloom-forming Lingulodinium polyedrum...

Amyotrophic lateral sclerosis (ALS) is the most common adult-onset paralytic disorder. It is characterized by progressive degeneration of the motor neurons controlling voluntary movement. The underlying mechanisms remain elusive, a fact that has precluded development of effective treatments. ALS presents as a sporadic condition 90-95% of the time, i.e., without familial history or obvious genetic mutation. This suggests that ALS has a strong environmental component. Organophosphates (OPs) are prime candidate neurotoxicants in the etiology of ALS, as exposure to OPs was linked to higher ALS incidence among farmers, soccer players, and Gulf War veterans...
