TL;DR: It is suggested that CD4+ T lymphocytes that produce IL-4, but not IFN-gamma, occur in high frequencies in the allergen-specific T cell repertoires of atopic donors, which may have important implications for the pathomechanism of atopy disease.
Abstract: Lymphokine secretion profiles were studied of human allergen-specific CD4+ T lymphocyte clones (TLC). To this aim, panels of house dust mite Dermatophagoides pteronyssinus (Dp)-specific TLC were generated from two atopic Dp-allergic patients, suffering from severe atopic dermatitis (AD1) and allergic asthma (AD2), respectively, and from a non-atopic individual (NAD). From AD1 additional TLC were cloned specific for tetanus toxoid or Candida albicans, both Ag that were not relevant for the atopic state of this patient. Secretion of IL-2, IL-4, and IFN-gamma was determined after specific stimulation of these TLC, using autologous monocytes as APC. With respect to the production of IL-4 and IFN-gamma, clearly distinct profiles were observed. All Dp-specific TLC from both atopic donors produced IL-4 but not IFN-gamma, whereas the Dp-specific TLC from NAD, as well as the tetanus toxoid- and C. albicans-specific TLC from AD1, all produced IFN-gamma but not or small quantities of IL-4. Most TLC from all panels produced IL-2. These lymphokine profiles were consistent for at least 3 days and were neither dependent on the dose of allergen nor on the atopic or nonatopic state of the donor of APC. The functional consequence of these restricted lymphokine profiles was stressed by the observation that, whereas Dp-specific TLC from AD1 and AD2 supported in vitro IgE production, this support could be abrogated by a Dp-specific TLC from NAD. The present results suggest that CD4+ T lymphocytes that produce IL-4, but not IFN-gamma, occur in high frequencies in the allergen-specific T cell repertoires of atopic donors, which may have important implications for the pathomechanism of atopic disease.

TL;DR: The requirements and the methodological issues to be addressed for using ABPM in clinical practice are addressed, the clinical indications for ABPM suggested by the available studies are outlined in detail, and the place of home measurement of blood pressure in relation to ABPM is discussed.
Abstract: Given the increasing use of ambulatory blood pressure monitoring (ABPM) in both clinical practice and hypertension research, a group of scientists, participating in the European Society of Hypertension Working Group on blood pressure monitoring and cardiovascular variability, in year 2013 published a comprehensive position paper dealing with all aspects of the technique, based on the available scientific evidence for ABPM. The present work represents an updated schematic summary of the most important aspects related to the use of ABPM in daily practice, and is aimed at providing recommendations for proper use of this technique in a clinical setting by both specialists and practicing physicians. The present article details the requirements and the methodological issues to be addressed for using ABPM in clinical practice, The clinical indications for ABPM suggested by the available studies, among which white-coat phenomena, masked hypertension, and nocturnal hypertension, are outlined in detail, and the place of home measurement of blood pressure in relation to ABPM is discussed. The role of ABPM in pharmacological, epidemiological, and clinical research is also briefly mentioned. Finally, the implementation of ABPM in practice is considered in relation to the situation of different countries with regard to the reimbursement and the availability of ABPM in primary care practices, hospital clinics, and pharmacies.

TL;DR: A new zero-shot learning dataset is proposed, the Animals with Attributes 2 (AWA2) dataset which is made publicly available both in terms of image features and the images themselves and compares and analyzes a significant number of the state-of-the-art methods in depth.
Abstract: Due to the importance of zero-shot learning, i.e. classifying images where there is a lack of labeled training data, the number of proposed approaches has recently increased steadily. We argue that it is time to take a step back and to analyze the status quo of the area. The purpose of this paper is three-fold. First, given the fact that there is no agreed upon zero-shot learning benchmark, we first define a new benchmark by unifying both the evaluation protocols and data splits of publicly available datasets used for this task. This is an important contribution as published results are often not comparable and sometimes even flawed due to, e.g. pre-training on zero-shot test classes. Moreover, we propose a new zero-shot learning dataset, the Animals with Attributes 2 (AWA2) dataset which we make publicly available both in terms of image features and the images themselves. Second, we compare and analyze a significant number of the state-of-the-art methods in depth, both in the classic zero-shot setting but also in the more realistic generalized zero-shot setting. Finally, we discuss in detail the limitations of the current status of the area which can be taken as a basis for advancing it.

TL;DR: XPC is identified as the earliest known NER factor in the reaction mechanism, insight is given into the order of subsequent NER components, evidence for a dual role of XPA is provided, and a concept of sequential assembly of repair proteins at the site of the damage rather than a preassembled repairosome is supported.
