The Immune Nature of Platelets Revisited

Platelets are the primary cellular mediators of hemostasis and this function firmly acquaints them with a variety of inflammatory processes. For example, platelets can act as circulating sentinels by expressing Toll-like receptors (TLR) that bind pathogens and this allows platelets to effectively kill them or present them to cells of the immune system. Furthermore, activated platelets secrete and

Avian Neo-Sex Chromosomes Reveal Dynamics of Recombination Suppression and W Degeneration

How the avian sex chromosomes first evolved from autosomes remains elusive as 100 million years (My) of divergence and degeneration obscure their evolutionary history. The Sylvioidea group of songbirds is interesting for understanding avian sex chromosome evolution because a chromosome fusion event ∼24 Ma formed "neo-sex chromosomes" consisting of an added (new) and an ancestral (old) part. Here,

Examination of the sensitivity of quasifree reactions to details of the bound-state overlap functions

It is often stated that heavy-ion nucleon knockout reactions are mostly sensitive to the tails of the bound-state wave functions. In contrast, (p,2p) and (p,pn) reactions are known to access information on the full overlap functions within the nucleus. We analyze the oxygen isotopic chain and explore the differences between single-particle wave functions generated with potential models, used in th

Downfolding the Su-Schrieffer-Heeger model

Charge-density waves are responsible for symmetry-breaking displacements of atoms and concomitant changes in the electronic structure. Linear response theories, in particular density-functional perturbation theory, provide a way to study the effect of displacements on both the total energy and the electronic structure based on a single ab initio calculation. In downfolding approaches, the electron

Short-distance HLbL contributions to the muon g-2

The current 3.7σ discrepancy between the Standard Model prediction and the experimental value of the muon anomalous magnetic moment could be a hint for the existence of new physics. The hadronic light-by-light contribution is one of the pieces requiring improved precision on the theory side, and an important step is to derive short-distance constraints for this quantity containing four electromagn

Suicide attempts are considered one of the most important risk factors for suicide. Based on this, various psychotherapeutic treatments for persons after a suicide attempt have been developed and evaluated in recent years. In this article, the current state of efficacy research is outlined, examples of successful suicide-focused psychotherapies are presented, and the current state of research and

Flow cytometric analysis of myelodysplasia : Pre-analytical and technical issues—Recommendations from the European LeukemiaNet

Background: Flow cytometry (FCM) aids the diagnosis and prognostic stratification of patients with suspected or confirmed myelodysplastic syndrome (MDS). Over the past few years, significant progress has been made in the FCM field concerning technical issues (including software and hardware) and pre-analytical procedures. Methods: Recommendations are made based on the data and expert discussions g

Construct validity, floor and ceiling effects, data completeness and magnitude of change for the eight-item HAKIR questionnaire : a patient-reported outcome in the Swedish National Healthcare Quality Registry for hand surgery

Introduction: The aim of this study was to evaluate the construct validity, floor and ceiling effects, data completeness and magnitude of change over time for the eight-item patient questionnaire (HQ-8) in the Swedish Healthcare Quality Registry for hand surgery (HAKIR). Methods: Construct validity was investigated through predefined hypotheses and correlation statistics between the single items i

Comparison of hemodialysis using a medium cutoff dialyzer versus hemodiafiltration : A controlled cross-over study

Purpose: Conventional hemodialysis (HD) treatment has an acceptable removal of small uremic molecules, but so-called middle molecules in the range of 0.5-60 kDa are poorly cleared with HD compared to a native kidney, which may contribute to morbidity in the dialysis population. Hemodiafiltration (HDF) has a better removal of middle molecules compared to HD but is technically demanding and requires

The Basis for Debating Standardization of Risk for Land-use Planning is Incomplete

The practice of using quantitative risk assessments (QRAs) for managing risks in land-use planning varies between countries. Some regulatory regimes are highly prescriptive in terms of explicit requirements on methodology, assumptions, modelling tools, input data, risk criteria, etc. Others require risk analyses to support decision-making without regulating the details. The present study seeks to

Mechanisms involved in regulation of periodontal ligament cell production of pro-inflammatory cytokines : Implications in periodontitis

It is well recognized that human periodontal ligament cells (PDL cells) may represent local immune cells of the periodontal tissues. However, it is unclear whether they represent “true” immune cells, since they can produce pro-inflammatory cytokines not only after stimulation with bacterial lipopolysaccharides but also in response to other stimuli such as mechanical stress. Stimulation with bacter

Risk of prostate cancer for men fathering through assisted reproduction: nationwide population based register study

Objective To compare the risk and severity of prostate cancer between men achieving fatherhood by assisted reproduction and men conceiving naturally.Design National register based cohort study.Setting Sweden from January 1994 to December 2014.Participants 1 181 490 children born alive in Sweden during 1994-2014 to the same number of fathers. Fathers were grouped according to fertility status by mo

Statin use, HMGCR expression, and breast cancer survival – The Malmö Diet and Cancer Study

Statins, commonly used to treat hypercholesterolemia, have also been proposed as anti-cancer agents. The identification of a predictive marker is essential. The 3-hydroxy-3-methylglutaryl-coenzyme-A reductase (HMGCR), which is inhibited by statins, might serve as such a marker. Thorough antibody validation was performed for four different HMGCR antibodies. Tumor expression of HMGCR (#AMAb90619, CL

Trajectory of excess healthcare consultations, medication use, and work disability in newly diagnosed knee osteoarthritis : a matched longitudinal register-based study

PURPOSE: To estimate the excess healthcare use and work disability attributable to knee osteoarthritis (OA) in the first five years following diagnosis.METHODS: Among individual aged 40-80 years who resided in Skåne on 31st December 2008, we identified those with a main diagnosis of knee OA during 2009-2014 and no previous diagnosis of any OA from 1998 (n=16,888). We created a comparison cohort ma

Serum perfluoroalkyl substances in residents following long-term drinking water contamination from firefighting foam in Ronneby, Sweden

BACKGROUND: In December 2013, it was discovered that drinking water supplied to one third of the households in Ronneby, southern Sweden, was highly contaminated by PFAS (sum level >10,000 ng/L) originated from firefighting foams used at a nearby military airport.OBJECTIVES: To report serum PFAS levels of Ronneby residents participating in a biomonitoring program, and to describe the variation by a

Implementation of hybrid particle swarm optimization-differential evolution algorithms coupled with multi-layer perceptron for suspended sediment load estimation

River suspended sediment load (SSL) estimation is of importance in water resources engineering and hydrological modeling. In this study, a novel hybrid approach is recommended for SSL estimation in which multi-layer perceptron (MLP) is hybridized with particle swarm optimization (PSO) and then, integrated with differential evolution algorithm (DE) called as MLP-PSODE. The hybrid MLP-PSODE model is

A Comparative Study of the Innate Humoral Immune Response to Avian Influenza Virus in Wild and Domestic Mallards

Domestic mallards (Anas platyrhynchos domesticus) are traditionally used as a model to investigate infection dynamics and immune responses to low pathogenic avian influenza viruses (LPAIVs) in free-living mallards. However, it is unclear whether the immune response of domestic birds reflects the response of their free-living counterparts naturally exposed to these viruses. We investigated the exte
