#1
Shoubiao Tan, Xi Sun, Wentao Chan, Lei Qu, Ling Shao
In this paper, a novel joint sparse representation method is proposed for robust face recognition. We embed both group sparsity and kernelized locality-sensitive constraints into the framework of sparse representation. The group sparsity constraint is designed to utilize the grouped structure information in the training data. The local similarity between test and training data is measured in the kernel space instead of the Euclidian space. As a result, the embedded nonlinear information can be effectively captured, leading to a more discriminative representation...

Importance: For a small percentage of obsessive-compulsive disorder (OCD) cases exhibiting additional neuropsychiatric symptoms, it was proposed that neuroinflammation occurs in the basal ganglia as an autoimmune response to infections. However, it is possible that elevated neuroinflammation, inducible by a diverse range of mechanisms, is important throughout the cortico-striato-thalamo-cortical circuit of OCD. Identifying brain inflammation is possible with the recent advance in positron emission tomography (PET) radioligands that bind to the translocator protein (TSPO)...

Hybrids between the indica and japonica subspecies of rice (Oryza sativa) are usually sterile, which hinders utilization of heterosis in the inter-subspecific hybrid breeding. The complex locus Sa comprises two adjacently located genes, SaF and SaM, which interact to cause abortion of pollen grains carrying the japonica allele in japonica-indica hybrids. Here we showed that silencing of SaF or SaM by RNA interference restored male fertility in indica-japonica hybrids with heterozygous Sa. We further used CRISPR/Cas9-based genome editing to knockout the SaF and SaM alleles respectively of an indica rice line to create hybrid-compatible lines...

A platform for the simultaneous determination of Cd(ii) and Pb(ii) in aqueous solution has been applied based on an aluminum silicon carbide-reduced graphene oxide nanocomposite (Al4SiC4-RGO) modified bismuth film glassy carbon electrode (GCE) using square wave anodic stripping voltammetry (SWASV) for the first time. The Al4SiC4-RGO nanocomposite electrode was characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Compared with the Al4SiC4 modified GCE and bare GCE, the electrochemical performance of the Al4SiC4-RGO nanocomposite electrode is obviously enhanced resulting from the synergistic effects of Al4SiC4, RGO and bismuth film...

Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) binds to its sole receptor fibroblast growth factor-inducible 14 (Fn14), participating in various inflammatory responses. Recently, TWEAK/Fn14 activation was found prominent in the lesions of cutaneous lupus erythematosus (CLE). This study was designed to further reveal the potential role of this pathway in Ro52-mediated photosensitization. TWEAK, Fn14, and Ro52 were determined in the skin lesions of patients with CLE. Murine keratinocytes received ultraviolet B (UVB) irradiation or plus TWEAK stimulation and underwent detection for Ro52 and proinflammatory cytokines...

The EstPS1 gene, which encodes a novel carboxylesterase of Pseudomonas synxantha PS1 isolated from oil well-produced water, was cloned and sequenced. EstPS1 has an open reading frame of 1923 bp and encodes the 640-amino acid carboxylesterase (EstPS1), which contains an autotransporter (AT) domain (357-640 amino acids). Homology analysis revealed that EstPS1 shared the highest identity (88%) with EstA from Pseudomonas fluorescens A506 (NCBI database) and belonged to the carboxylesterase family (EC 3.1.1.1). The optimum pH and temperature of recombinant EstPS1 were found to be 8...

Starch phosphorylation occurs naturally during starch metabolism in the plant and is catalysed by glucan water dikinases (GWD1) and phosphoglucan water dikinase/glucan water dikinase 3 (PWD/GWD3). We generated six stable individual transgenic lines by over-expressing the potato GWD1 in rice. Transgenic rice grain starch had 9-fold higher 6-phospho (6-P) monoesters and double amounts of 3-phospho (3-P) monoesters, respectively, compared to control grain. The shape and topography of the transgenic starch granules were moderately altered including surface pores and less well defined edges...

Biofilms are difficult to eradicate due to their resistance to antibiotics and host immune cells. Ultrasound microbubbles have emerged as a new treatment modality with the underlying mechanisms largely unknown. In this study, we exposed 24-h-old Staphylococcus epidermidis biofilms established in OptiCell™ chambers to ultrasound in combination with microbubbles, and investigated the activities of vancomycin and neutrophils against S. epidermidis biofilms after treatment. The antibiofilm mechanims of ultrasound microbubbles were explored in terms of bacterial permeability and biofilm-associated gene expression...

As a fundamental component of nucleic acids, phospholipids and adenosine triphosphate, phosphorus (P) is critical to all life forms. However, the molecular mechanism of P translocation and distribution in rice grains are still not understood. Here, with the use of five different low phytic acids (lpa) rice mutants, the redistribution in the main P-contained compounds in rice grain, i.e. phytic acid (PA), lysophospholipid (LPL) and inorganic P (Pi) were investigated. The lpa mutants showed a significant decrease in PA and phytate-phosphorus (PA-P) concentration with the concomitant increase in Pi concentration...

OBJECTIVE: To date, few studies of childhood obsessive compulsive disorder (OCD) have been adequately powered to examine patterns and predictors of comorbidity, despite the frequency with which it occurs. We address this gap, drawing on a large sample of youth with OCD who were systematically assessed through research and clinical programs in a university-based specialty program for children and adolescents with OCD. We examine patterns of comorbidity across different epochs of development and predict specific classes of OCD (comorbidity internalizing/externalizing/both) from key demographic and clinical variables that may be useful in guiding individualized treatment...

BACKGROUND: Catheter ablation of para-Hisian accessory pathways (APs) can be challenging because of adjacent conduction tissue. Some different approaches for ablation, including the inferior vena cava approach (IVC-A), the noncoronary cusp approach (NCC-A), or the superior vena cava approach (SVC-A), have been reported. However, when should para-Hisian APs be mapped and ablated by the IVC-A, NCC-A, or SVC-A is not well established. METHODS AND RESULTS: This study included 55 consecutive patients (mean age, 53±11 years, 36 males) with para-Hisian APs...

OBJECTIVES: The potential role of an addictive process in problematic eating is a growing area of interest and debate. Children are more vulnerable to the negative effects of addictive substances than adults and may be at increased risk for addictive-like eating behavior. No prior study has evaluated the association of addictive-like eating with objectively measured eating behavior in adults or children. We examined the association between "food addiction" and observed food consumption among children and whether age moderated this association...
