Pharmacological modulation of T cell immunity results in long-term remission of autoimmune arthritis

Chronic inflammatory diseases like rheumatoid arthritis are characterized by a deficit in fully functional regulatory T cells. DNA-methylation inhibitors have previously been shown to promote regulatory T cell responses and, in the present study, we evaluated their potential to ameliorate chronic and acute animal models of rheumatoid arthritis. Of the drugs tested, decitabine was the most effectiv

The forgotten sub-regional COVID-19 response layer2021 : The case of the WHO Eastern Mediterranean Region

The response to the COVID-19 pandemic have been driven by epidemiology, health system characteristics and control measures in form of social/physical distancing. Guidance, information and best practices have been characterized by territorial thinking with concentration on national health system and social contexts. Information was to a large extent provided from global entities such as the World H

Neuroscience : Flies and grits

Food texture affects palatability. A new study finds that the common dew fly Drosophila melanogaster is also choosy when it comes to food texture. Flies evaluate size and presence of food particles through neurons in the tongue that express the mechanically activated channel protein TMEM63.

Association between sugar intake and intima media thickness as a marker for atherosclerosis : A cross-sectional study in the Malmö diet and cancer study (Sweden)

It has been suggested that sugar intake may play a role in the development of atherosclero-sis. However, studies on this matter are lacking. Intima media thickness (IMT) is a well-established measurement of subclinical atherosclerosis. This study aimed to investigate the cross-sectional association between sugar intake (i.e., added, free and total sugar and sugar-rich foods and beverages) and IMT.

Systemic opioid regimens for postoperative pain in neonates

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of different regimens of systemic opioid analgesics in neonates (term or preterm) undergoing surgery, on mortality, pain and major neurodevelopmental disability. These different regimens may include: different doses of the same opioid; different routes of administration of

A community effort to identify and correct mislabeled samples in proteogenomic studies

In a community effort to combat sample mislabeling in multi-omic studies, computational solutions received show a wide range of accuracy. The final collaborative product, COSMO, achieves high performance. Applying COSMO to published datasets demonstrates biological impact of the tool.Sample mislabeling or misannotation has been a long-standing problem in scientific research, particularly prevalent in large-scale, multi-omic studies due to the complexity of multi-omic workflows. There exists an urgent need for implementing quality controls to automatically screen for and correct sample mislabels or misannotations in multi-omic studies. Here, we describe a crowdsourced precision

Systemic opioids versus other analgesics and sedatives for postoperative pain in neonates

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of systemic opioid analgesics in neonates (term or preterm) undergoing surgery, on mortality, pain and major neurodevelopmental disability, compared to placebo or no drug, non-pharmacological intervention, other opioids, or other analgesics or sedatives.

Comparable Initial Engagement of Intracellular Signaling Pathways by Parathyroid Hormone Receptor Ligands Teriparatide, Abaloparatide, and Long-Acting PTH

Multiple analogs of parathyroid hormone, all of which bind to the PTH/PTHrP receptor PTH1R, are used for patients with osteoporosis and hypoparathyroidism. Although ligands such as abaloparatide, teriparatide (hPTH 1-34 [TPTD]), and long-acting PTH (LA-PTH) show distinct biologic effects with respect to skeletal and mineral metabolism endpoints, the mechanistic basis for these clinically-important

Molecular Mechanisms of Graves' Ophthalmopathy. A focus on smoking and radioiodine.

Graves’ disease (GD) is an autoimmune disease characterized by hyperthyroidism and is caused by an interplayof genetic and environmental factors. One-third of patients with GD develop Graves’ ophthalmopathy (GO). Keyprocesses in the pathogenesis of GO are inflammation and adipogenesis in orbital tissue. Strong risk factorsassociated with the development of GO are smoking and radioiodine treatment

Are we observing an NSC in course of formation in the NGC 4654 galaxy?

We use direct N-body simulations to explore some possible scenarios for the future evolution of two massive clusters observed towards the centre of NGC 4654, a spiral galaxy with mass similar to that of the Milky Way. Using archival HST data, we obtain the photometric masses of the two clusters, M = 3 × 105 M= and M = 1.7 × 106 M=, their half-light radii, Reff ∼4 pc and Reff ∼6 pc, and their proje

Examining evacuee response to emergency communications with agent-based simulations

To improve communication during emergencies, this research introduces an agent-based modeling (ABM) method to test the effect of psychological emergency communication strategies on evacuation performance. We follow a generative social science approach in which agent-based simulations allow for testing different candidate solutions. Unlike traditional methods, such as laboratory experiments and fie

MicroRNA-Mediated Migration of Colon Cancer Cells

Colorectal cancer (CRC) is the second most common cancer in women and third most common cancer in men worldwide. The cause of the majority of death related to CRC is believed to be the migration of cancer cells to distant organs which is known as cancer metastasis. The mechanism behind cancer cell metastasis is not fully understood but accumulating studies suggest that it could be due to enhanced

Commentaries from Erik J. Olsson

In this chapter, the author argues that there are cases in which a nonexpert’s autonomously-formed belief is based on evidence that would otherwise be sufficient for justification, but where this belief is rendered unjustified by (potential) evidence which the nonexpert fails to take into account. He gives various examples in support of his claim. One involves Roger, a food scientist for a large f

Commentary from Erik J. Olsson

The term hypothesis denotes something like a policy proposal rather than a factual claim. An organisational tool stands a greater chance of success if it is easy and fun to work with. Better Beliefs represents the current credibility status of hypotheses using the amusing analogy with a horse race, each horse representing a hypothesis. The colour of a horse depends on the votes and evidence provid

Perfusion Monitoring of Advancement and Rotational Flaps. Oculoplastic Surgery and Laser Speckle Contrast Imaging.

Flaps are widely used in oculoplastic reconstructive surgery to cover defects following the removal of tumors, malformations, or trauma. Adequate blood perfusion of the flap is crucial for its survival. Knowledge about the perfusion in different type of flaps is therefore of great value. The main aim of the studies presented in this thesis was to investigate the changes in blood perfusion in advan

MET Expression and Cancer Stem Cell Networks Impact Outcome in High-Grade Serous Ovarian Cancer

Overexpression of the receptor tyrosine kinase MET has been linked to poor survival in several cancer types, and MET has been suggested to interact with stem cell networks. In vitro studies have further suggested a possible benefit of a combined treatment using PARP and MET inhibitors. We used a tissue microarray (TMA) with 130 samples of advanced-stage high-grade serous fallopian tube/ovarian can

Amândoi by Liviu Rebreanu : multicultural settings and sources of suspense

The article looks into the multicultural settings of Liviu Rebreanu’s novel “Amândoi” (Both) by briefly examining the representation of its main, minor or incidental characters, either intelligentsia or common people. Ethnicity, social and professional statuses are considered as elements of multiculturalism. The continuous increase of suspense, the open ending, the parody in the undertone, and the
