The mitogenic lectins are invaluable tools to study the biochemical changes associated with lymphocyte activation and proliferation of various immune cells. Rachycentron canadum lectin (RcaL) was detected and purified from serum of cobia fish. The aim of this study was to evaluate the proliferative response and cytokin... |
The Anglo-Saxon period has been characterised as playing no part in accounting history. The article appraises whether this view can be sustained in the light of current knowledge. A review of the use of written English, accounting in the Church, governmental financial planning, the dissemination of accounting practice ... |
Lichen sclerosus, a rare, chronic, inflammatory, mucocutaneous disorder of the genital and extragenital skin, is usually asymptomatic and affects both sexes. The exact cause of lichen sclerosus is unknown. Extragenital lichen sclerosus may be localized or disseminated. Linear extragenital lichen sclerosis following the... |
A decision-making model is discussed which can serve as a logical aid or conceptual base for structuring certain problems and implicitly analyzing the available strategies. The method is especially appropriate in situations where a more detailed quantitative analysis has been rejected for reasons such as shortage of ti... |

The nephron number is thought to be associated with clinical outcomes of chronic kidney disease (CKD). If the nephron number can be estimated in a clinical setting, it could become a strong tool to predict the outcomes. This preliminary study estimated nephron number in CKD patients, and examined the relationship betw... |
Data from a multicenter study of the National Hospital Organization of Japan were analyzed, including 565 CKD patients aged over 14 years who underwent a kidney biopsy. The nephron number was estimated by the glomerular density in biopsy specimens and the renal cortex volume. The renal cortex volume was calculated by ... |
A total of 50% of the patients were women, and the mean (±SD) age of the patients was 51±19 years. The mean eGFR was 63±32 ml/min/1.73m2, and the mean estimated number of non-sclerotic nephrons was 660,000±320,000 per kidney. A larger number of estimated nephron number was associated with younger age, male sex, and hi... |
To the best of our knowledge, this was the first study to estimate the renal cortex volume and nephron number of CKD patients in the general clinical setting. The results from this study should provide powerful tools for nephrologists in routine clinical practice. Further investigations will be needed to verify the as... |
NONPARAMETRIC CONTROL CHARTS FOR VARIABILITY USING RUNS RULES |
In this paper, two Shewhart-type nonparametric control charts based on runs rules are developed for monitoring the changes in the process variability. The charts are based on two nonparametric tests for equality of variances. The performance of the proposed control charts is evaluated for the normal, light tailed and h... |
Side-channel attacks (SCA) pose significant threats to the hardware security of embedded devices. Various logical and circuit-level countermeasures propose security, but they all come with different power, performance, and area overhead. Besides countermeasures cannot guarantee security, if the adversaries have enough ... |
Restless legs syndrome (RLS) is characterized by discomfort and paresthesias in the legs with urge to move the legs, worsening of the symptoms with the rest or inactivity, present or exacerbation in the evening or night and partial or total relief with movement. The diagnosis is primarily clinical. RLS is idiopathic, w... |

We propose a model for adaptation and implicit coordination in multi-robot systems based on the definition of artificial emotions, which play two main roles: modulators of individual robot behavior, and means of communication among different robots for system-level social coordination. We model emotions as compressed r... |

The low-noise readout of large pixellated detectors, especially when the number grows into the hundreds, represents a challenge for both front-end and back-end electronics. The TRISTAN project for keV-scale sterile neutrino search is planning to install a 3486-pixel Silicon Drift Detector (SDD) matrix into KATRIN exper... |
This letter considers a direct current-biased optical orthogonal frequency division multiplexing (DCO-OFDM) with intensity-modulated direct-detection modulation for visible light communication systems. The high peak-to-average power ratio (PAPR) is a critical performance-limiting factor for the DCO-OFDM system. To redu... |
We report a branched polyethyleneimine (BPEI)-quantum dot (QD) based rewritable fluorescent system with a multicolor recording mode, in which BPEI is both QD-multicolor patterning "writer" and data erasing "remover". This method could write distinct colors from size-tailored QDs to represent large numbers of logic stat... |
Plastic pollution is one of the most visible problems in many regions, especially in developing Asian and African countries, which lack of proper garbage collection systems. Everyone in societies need to work together in dealing with plastic pollution. The purpose of this article is to examine how plastic pollution eff... |
We present observations of Hα emission of Stephan's Quintet obtained with a scanning Fabry-Perot interferometer and samplings of ~11 km s-1 and ~1''. Our observations show an intragroup arclike feature formed of bright Hα knots and diffuse gas distributed along tidal tails associated with NGC 7318B and possibly also NG... |
Abstract A concept of feature informativeness was introduced as a way of measuring the discriminating power of a set of features. A question of interest is how this property of features affects the discrimination performance. The effect is assessed by means of a weighted discriminant function, which distributes weights... |

ABSTRACT The abundance and diversity of archaeal ammonia monooxygenase subunit A (amoA) genes from hydrothermal vent chimneys at the Juan de Fuca Ridge were investigated. The majority of the retrieved archaeal amoA sequences exhibited identities of less than 95% to those in the GenBank database. Novel ammonia-oxidizing... |
Feature selection refers to the problem of selecting those input features that are most predictive of a given outcome; a problem encountered in many areas such as machine learning, pattern recognition and signal processing. In particular, this has found successful application in tasks that involve datasets containing h... |

RATIONALE |
In a guinea pig model of allergic asthma, using perfused tracheal preparations ex vivo, we demonstrated that L-arginine limitation due to increased arginase activity underlies a deficiency of bronchodilating nitric oxide (NO) and airway hyperresponsiveness (AHR) after the allergen-induced early and late asthmatic react... |
OBJECTIVES |
Using the same animal model, we investigated the acute effects of the specific arginase inhibitor 2(S)-amino-6-boronohexanoic acid (ABH) and of L-arginine on AHR after the early and late reaction in vivo. In addition, we investigated the protection of allergen-induced asthmatic reactions, AHR, and airway inflammation b... |
METHODS |
Airway responsiveness to inhaled histamine was measured in permanently instrumented, freely moving guinea pigs sensitized to ovalbumin at 24 hours before allergen challenge and after the allergen-induced early and late asthmatic reactions by assessing histamine PC(100) (provocative concentration causing a 100% increase... |
MEASUREMENTS AND MAIN RESULTS |
Inhaled ABH acutely reversed AHR to histamine after the early reaction from 4.77 +/- 0.56-fold to 2.04 +/- 0.34-fold (P < 0.001), and a tendency to inhibition was observed after the late reaction (from 1.95 +/- 0.56-fold to 1.56 +/- 0.47-fold, P < 0.10). Quantitatively similar results were obtained with inhaled l-argin... |
CONCLUSIONS |
Inhalation of ABH or l-arginine acutely reverses allergen-induced AHR after the early and late asthmatic reaction, presumably by attenuating arginase-induced substrate deficiency to NO synthase in the airways. Moreover, ABH considerably reduces the airway sensitivity to inhaled allergen and protects against allergen-in... |
Pre-exposure prophylaxis (PrEP) of HIV infection with antiretroviral therapy (ART) was recently found to reduce HIV infection through sexual contact in men who have sex with men (MSM).1 Non-prescribed use and sharing of ART to prevent HIV infection were reported by MSM in the USA before efficacy was determined.2 We rep... |

Let ℰ be an additive category and 𝒞 a full subcategory with split idempotents, and closed under isomorphic images and finite direct sums. We give conditions on ℰ and 𝒞 implying that ℰ embeds into an abelian category, so that the objects of 𝒞 turn into injective objects. This construction generalizes the embedding of... |
