Terahertz Spectroscopic Analysis of Lactose in Infant Formula : Implications for Detection and Quantification

Lactose plays a significant role in daily lives as a constituent of various food and pharmaceutical products. Yet, lactose intolerance conditions demand low-lactose and lactose-free products in the market. These increasing nutritional claims and labels on food products entail simple and reliable methods of analysis that can be used for meeting quality standards, nutritional claims and legal requir

Performance improvement of proton exchange membrane fuel cells with wavy flow channels : An experimental study

The gas flow field design plays a vital role in the cell performance of proton exchange membrane fuel cells, especially at high current densities. In this study, wavy flow channels are designed and adopted on the cathode side to enhance the mass transport process. Results demonstrate that the wavy flow channels proposed in this paper significantly improve cell performance at high current densities

Allometric scaling of a superposition eye optimizes sensitivity and acuity in large and small hawkmoths

Animals vary widely in body size within and across species. This has consequences for the function of organs and body parts in both large and small individuals. How these scale, in relation to body size, reveals evolutionary investment strategies, often resulting in trade-offs between functions. Eyes exemplify these trade-offs, as they are limited by their absolute size in two key performance feat

Cognitive Behavioral Therapy and Acceptance and Commitment Therapy (CBT-ACT) vs. Standard Care After Critical Illness Due to COVID-19 : Protocol for a Pilot Randomized Controlled Trial

Background: Post-covid syndrome is an emerging condition involving a wide range of symptoms, including high rates of poor mental health. The diagnostic relevance and clinical severity of these symptoms are largely unknown, and evidence for treatment of post-covid mental health symptoms is lacking. This protocol describes a pilot randomized clinical trial, primarily aiming to assess feasibility, pa

Association of thyroid function with blood pressure and cardiovascular disease : A mendelian randomization

Thyroid function has a widespread effect on the cardiometabolic system. However, the causal association between either subclinical hyper-or hypothyroidism and the thyroid hormones with blood pressure (BP) and cardiovascular diseases (CVD) is not clear. We aim to investigate this in a two-sample Mendelian randomization (MR) study. Single nucleotide polymorphisms (SNPs) associated with thyroid-stimu

CD244 expression represents functional decline of murine hematopoietic stem cells after in vitro culture

Isolation of long-term hematopoietic stem cell (HSC) is possible by utilizing flow cytometry with multiple cell surface markers. However, those cell surface phenotypes do not represent functional HSCs after in vitro culture. Here we show that cultured HSCs express mast cell-related genes including Cd244. After in vitro culture, phenotypic HSCs were divided into CD244- and CD244+ subpopulations, an

Rationale and design of the “NEurodegeneration : Traumatic brain injury as Origin of the Neuropathology (NEwTON)” study: a prospective cohort study of individuals at risk for chronic traumatic encephalopathy

Background: Repetitive head injury in contact sports is associated with cognitive, neurobehavioral, and motor impairments and linked to a unique neurodegenerative disorder: chronic traumatic encephalopathy (CTE). As the clinical presentation is variable, risk factors are heterogeneous, and diagnostic biomarkers are not yet established, the diagnostic process of CTE remains a challenge. The general

A randomized controlled trial in schools aimed at exploring mechanisms of change of a multifaceted implementation strategy for promoting mental health at the workplace

Background: This study will explore implementation mechanisms through which a single implementation strategy and a multifaceted implementation strategy operate to affect the implementation outcome, which is fidelity to the Guideline For The Prevention of Mental Ill Health within schools. The guideline gives recommendations on how workplaces can prevent mental ill health among their personnel by ma

Non-opioid analgesics for procedural pain in neonates

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of non-opioid analgesics in neonates (term or preterm) exposed to procedural pain compared to placebo or no drug, non-pharmacological intervention, other analgesics, or different routes of administration.

Lack of autoantibodies against collagen and related proteins in collagenous colitis

INTRODUCTION: Collagenous colitis (CC) is a common cause of chronic diarrhea and is characterized by a subepithelial thickened collagen layer in the colonic mucosa. It shares many of the characteristics found in autoimmune diseases, but no autoantibodies have been identified. In CC, an imbalance in collagen turnover is evident. The purpose of the present study was to investigate whether any collag

Investigating out-of-plane strength & stiffness of a nailed glulam connection

During March 2020 a large-span arena, Tarfalahallen, collapsed. The main load-bearing girders with a 54 m span were high and slender glulam trussed beams, supported from below by a cable system via vertical struts. Investigations concluded that the failure was initiated by out-of-plane buckling of the struts and slender beam, in spite of lateral stabilization by steel roof sheeting at the top edge

Arlie Russell Hochschild: Känsloregler och emotionsarbete i kommersialiserade relationer.

Vad ska en surrogatmamma känna inför fostret hon bär i sin mage? Hur ska en hårt arbetande förälder förhålla sig till faktumet att nannyn eller kalasfixaren vet bäst hur deras barn vill ha sitt kalas? Kan en flygvärdinna eller en socialarbetare visa den irritation hon känner inför en otrevlig kund eller klient? Vilka känslor är legitima att visa upp i olika situationer och vilka behöver tryckas ne

Pathways to a Sustainable Blue Economy in Latin America and the Caribbean

After a 7-year slowdown in economic growth in the previous decade, LAC opened this decade with the adverse effects of Covid. The economic slowdown and the health crisis jeopardized the SDGs’ implementation in the region. In this chapter, the authors revisit the old question of whether the previous decade of LAC is another lost decade, mainly adding the environmental dimension to the economic and s
