SSL-3

Staphylococcus aureus is a noteworthy pathogen in allergic diseases, as four staphylococcal exotoxins activate mast cells, a significant contributor to inflammation, in an IgE-independent manner. Although the adhesion of mast cells is an essential process for their immune responses, only a small number of exotoxins have been reported to affect the process. Here, we demonstrated that staphylococcal superantigen-like (SSL) 3, previously identified as a toll-like receptor 2 agonist, induced the adhesion of murine bone marrow-derived mast cells to culture substratum...

PURPOSE: Non-neuroendocrine neoplasms of the appendix are a phenotypically heterogeneous group of lesions; a comprehensive molecular characterization of these tumors is still lacking. METHODS: A total of 52 samples taken from 49 patients was evaluated: 18 sessile serrated lesions (SSL; 3 with dysplasia), 2 high-grade tubular adenomas, 1 tubulo-villous adenoma,1 hyperplastic polyp, 18 low-grade appendiceal mucinous neoplasms (LAMN), 3 high-grade appendiceal mucinous neoplasms (HAMN) and 9 mucinous adenocarcinomas...

The green microalga Botryococcus braunii produces hydrocarbon oils at 25-75% of its dry weight and is a promising source of biofuel feedstock. Few studies have examined this species' ecology in natural habitats, and few wild genetic resources have been collected due to difficulties caused by its low abundance in nature. This study aimed to develop a real-time PCR assay for specific detection and quantification of this alga in natural environments and to quantify spatiotemporal variations of wild B. braunii populations in a tropical pond...

OBJECTIVES: To investigate whether (1) the type of fixation at the shaft (hybrid vs. locking), (2) the position of the plate (offset vs. contact) and (3) the implant material has a significant effect on (a) construct stiffness and (b) fatigue life in a distal femur extraarticular comminuted fracture model using the same design of distal femur periarticular locking plate. METHODS: An extraarticular severely comminuted distal femoral fracture pattern (OTA/AO 33-A3) was simulated using artificial bone substitutes...

Solar ultraviolet irradiation is an environmental carcinogen that causes skin cancer. Caspase-7 is reportedly expressed at reduced levels in many cancers. The present study was designed to examine the role of caspase-7 in solar-simulated light (SSL)-induced skin cancer and to elucidate its underlying molecular mechanisms. Our study revealed that mice with genetic deficiency of caspase-7 are highly susceptible to SSL-induced skin carcinogenesis. Epidermal hyperplasia, tumor volume and the average number of tumors were significantly increased in caspase-7 knockout (KO) mice compared with SKH1 wild-type mice irradiated with SSL...

Semi-supervised learning (SSL) is a typical learning paradigms training a model from both labeled and unlabeled data. The traditional SSL models usually assume unlabeled data are relevant to the labeled data, i.e., following the same distributions of the targeted labeled data. In this paper, we address a different, yet formidable scenario in semi-supervised classification, where the unlabeled data may contain irrelevant data to the labeled data. To tackle this problem, we develop a maximum margin model, named tri-class support vector machine (3C-SVM), to utilize the available training data, while seeking a hyperplane for separating the targeted data well...

OBJECTIVE: To study the prevalence, clinical associations, and functional implications of the His159Tyr mutation of the BAFF receptor (BAFF-R) in patients with Sjögren's syndrome (SS). METHODS: The BAFF-R His159Tyr mutation was evaluated using polymerase chain reaction (PCR)-based assays in 247 patients with SS (of whom 70 had SS complicated by lymphoma [SS-lymphoma]), 145 with systemic lupus erythematosus (SLE), and 101 with rheumatoid arthritis (RA), as well as 180 healthy controls...

In our previous study, we observed a linear system consisted of sympathetic endings in the arrector pili muscles (AP muscles) along the rat skin termed sympathetic substance lines, or SSLs. After shaving the hair of the rats, the first wave of hair re-growth was not evenly distributed, but followed specific hair loop lines (HLLs). The patterns of HLL and SSL correspond with each other and also with the "Meridians" described in Chinese traditional medicine (CTM). Here I investigated in rabbits and rats whether the acupuncture signals are transmitted via the SSL/HLL, and whether the acupuncture analgesia (AA) is dependent on any peripheral mechanism...

Semisupervised learning (SSL) problem, which makes use of both a large amount of cheap unlabeled data and a few unlabeled data for training, in the last few years, has attracted amounts of attention in machine learning and data mining. Exploiting the manifold regularization (MR), Belkin et al. proposed a new semisupervised classification algorithm: Laplacian support vector machines (LapSVMs), and have shown the state-of-the-art performance in SSL field. To further improve the LapSVMs, we proposed a fast Laplacian SVM (FLapSVM) solver for classification...

We assessed the effects of applying stabilized sewage sludge (SSL) and composted sewage sludge (CLV), at 5 and 10% to an acid mining soil. Limed soil (NCL) amended or not with SSL and CLV was incubated for 47 days. We studied the cations and organic and inorganic anions in the soil solution by means of ion chromatography. Liming led to big increases in Ca(2+) and SO4(2-) and to significant decreases in K(+), Mg(2+), NH4(+) and NO3(-). Addition of both organic amendments increased some cations (NH4(+), K(+), Mg(2+), Na(+)) and anions (Cl(-), NO3(-) only with CLV and PO4(3-) only with SSL) and provided a greater amount of low-molecular-weight organic acids (LMWOAs) (SSL more than CLV)...

Many techniques for laparoscopic appendectomy have been proposed with few comparative studies. We performed a retrospective review of all patients undergoing laparoscopic appendectomy for uncomplicated appendicitis from 2006 to 2011. Techniques were: (1) transection of the mesoappendix and appendix with a single staple line (SSL); (2) transection of the mesoappendix and appendix with multiple staple lines (MSL); and (3) transection of the mesoappendix with ultrasonic shears and the appendix with a single staple line (USSL)...

The present study aimed to identify social and individual factors associated with satisfaction with sexual life (SSL) in people living with HIV (PLHIV) in contact with a community-based organisation in Romania. A standardised questionnaire was administered (N = 300) in a community-based research study. Multivariate analysis (using a weighted logistic regression restricted to the 291 respondents who answered a question about SSL) was used to determine factors associated with SSL. Sixty-eight per cent of the participants declared that they were satisfied with their sexual life...

BACKGROUND: The present study sought to compare the length of stay (LOS) and hospital costs for elective single-site (SSL) and standard laparoscopic (SDL) colorectal resections performed at a tertiary referral center. METHODS: An IRB-approved, retrospective cohort study of all elective SDL and SSL colorectal resections performed from 2008 to 2012 was undertaken. Patient charges and inflation adjusted hospital costs (US dollars) were compared with costs subcategorized by operating room expense, room and board, and pharmacy and radiology utilization...

Although it is widely recognized that microorganisms are essential for sustaining soil fertility, structure, nutrient cycling, groundwater purification, and other soil functions, soil microbial toxicity data were excluded from the derivation of Ecological Soil Screening Levels (Eco-SSL) in the United States. Among the reasons for such exclusion were claims that microbial toxicity tests were too difficult to interpret because of the high variability of microbial responses, uncertainty regarding the relevance of the various endpoints, and functional redundancy...
