Optimizing NOM removal : Impact of calcium chloride

Understanding the character of natural organic matter (NOM) and assessing its impact on water quality is paramount for managers of catchments and water utilities. For drinking-water producers, NOM affects disinfectant demand and the formation of by-products which can have adverse health effects. NOM content in raw waters also has an impact on water treatment processes by increasing required coagul

Histidine protonation states are key in the LigI catalytic reaction mechanism

Lignin is one of the world's most abundant organic polymers, and 2-pyrone-4,6-dicarboxylate lactonase (LigI) catalyzes the hydrolysis of 2-pyrone-4,6-dicarboxylate (PDC) in the degradation of lignin. The pH has profound effects on enzyme catalysis and therefore we studied this in the context of LigI. We found that changes of the pH mostly affects surface residues, while the residues at the active

Antibody kinetics and clinical course of COVID-19 a prospective observational study

Background Serological response and association to clinical manifestation is important for understanding the pathogenesis of COVID-19. Materials and methods A prospective observational study was conducted where antibody responses of IgG and IgA towards SARS-CoV-2 spike protein were studied over time in patients with COVID-19. Possible associations between antibody titers and outcome were analyzed.

Experiences matter: A longitudinal study of individual-level sources of declining social trust in the United States

The US has experienced a substantial decline in social trust in recent decades. Surprisingly few studies analyze whether individual-level explanations can account for this decrease. We use three-wave panel data from the General Social Survey (2006–2014) to study the effects of four possible individual-level sources of changes in social trust: job loss, social ties, income, and confidence in politi

Peace and Feminist Foreign Policy

In recent decades, there has been a global recognition of the co-constitutive relationship between gender justice and peaceful transformation of previously war-torn societies. This chapter investigates how “women-friendly states” have located their foreign policies within notions of gender equality and empowerment. It focuses on how feminist foreign policy is to all intents and purposes ethical an

PEPRF : Identification of Essential Proteins by Integrating Topological Features of PPI Network and Sequence-based Features via Random Forest

Background: Essential proteins play an important role in the process of life, which can be identified by experimental methods and computational approaches. Experimental approaches to identify essential proteins are of high accuracy but with the limitation of time and resource-consuming. Objective: Herein, we present a computational model (PEPRF) to identify essential proteins based on machine lear

Purse of medieval silver coins from royal shipwreck revealed by X-ray microscale Computed Tomography (µCT) scanning

We present the archaeological discovery and microscale X-ray Computed Tomography (µCT) scanning of a silver coin purse lost in a medieval shipwreck while the king who issued many of the coins was aboard. The find demonstrates that shipwrecks are extraordinary repositories of historical information, in this case providing insight into one of the most important and dramatic events of medieval Scandi

Importance of resting heart rate

Resting heart rate is a determinant of cardiac output and physiological homeostasis. Although a simple, but critical, parameter, this vital sign predicts adverse outcomes, including mortality, and development of diseases in otherwise normal and healthy individuals. Temporal changes in heart rate can have valuable predictive capabilities. Heart rate can reflect disease severity in patients with var

Alternative translation and retrotranslocation of cytosolic C3 that detects cytoinvasive bacteria

Complement C3 was originally regarded as a serum effector protein, although recent data has emerged suggesting that intracellular C3 can also regulate basic cellular processes. Despite the growing interest in intracellular C3 functions, the mechanism behind its generation has not been demonstrated. In this study we show that C3 can be expressed from an alternative translational start site, resulti

The human TRPA1 intrinsic cold and heat sensitivity involves separate channel structures beyond the N-ARD domain

TRP channels sense temperatures ranging from noxious cold to noxious heat. Whether specialized TRP thermosensor modules exist and how they control channel pore gating is unknown. We studied purified human TRPA1 (hTRPA1) truncated proteins to gain insight into the temperature gating of hTRPA1. In patch-clamp bilayer recordings, ∆1-688 hTRPA1, without the N-terminal ankyrin repeat domain (N-ARD), wa
