Timely light exposure is a vital aspect to achieve better sleep and well-being. As there are risks with a disturbed circadian rhythm and benefits with light settings that stimulate the rhythm, the circadian effective light, circadian stimulus (CS), for radiographers was examined. Aim: The aim of the study was to compare radiographers’ light environment on the workstations, at a university hospital

Hemoglobin (Hb) can produce reactive oxygen species, including superoxide anions, which are intrinsically toxic. Superoxide dismutase (SOD) is present in red blood cells (RBCs) and provides important protection against such oxidative stress. Upon hemolysis, Hb becomes released from the RBCs and the normal protection systems involving SOD and catalase become very inefficient. In these instance

Human peripheral blood mononuclear cells (PBMCs) can be easily sampled from healthy individuals and patients. Density gradient isolation from human blood or leukocyte concentrates yields a mononuclear cell population of mainly lymphocytes, monocytes, and natural killer (NK) cells. PBMCs are vital circulating cells of the immune system and rely on oxidative phosphorylation (OXPHOS) for their energy

Female-producing parthenogenesis is widespread in stick insects. It ranges from rare in sexual species to facultative or obligate, the latter sometimes in hybrids. This review synthesizes current knowledge on its origins, mechanisms, and evolutionary consequences, highlighting the distinction between hybrid and intra-specific origins. Hybrid-derived parthenogens are rare, obligate, frequently poly

PURPOSE OF REVIEW: This review aims to give an overview of recent advances in the clinical management of children <18 years of age with end-stage pulmonary hypertension refractory to conventional medical therapy.RECENT FINDINGS/SUMMARY: The increased awareness and characterization of pediatric pulmonary vascular disease has amounted more data toward creating an accurate, and comprehensive, risk pr

Most flowering plants depend on insect pollinators for their reproduction, yet these pollinators have been facing considerable losses in abundance and diversity in recent decades. The ongoing pollinator declines, caused by stressors including land-use and climate change, have raised concerns for species-rich plant communities such as those found in semi-natural grasslands. These communities contai

Populärvetenskaplig sammanfattning: Sahel kallas regionen som ligger mellan Saharaöknen i norr och den gröna savannen i söder. Det sträcker sig från Atlanten i väst till Röda havet i öst. Området karakteriseras av låg och oregelbunden nederbörd. Torka och svält har drabbat stora delar av området i flera omgångar. Den stora torkan 1984 lever kvar i folks minne som en fruktansvärd katastrof. SatellRecent research has shown significant increasing trends in NOAA NDVI for the Sahel region during the period of 1982-1999. These observations could indicate that the amount of vegetation in the region is increasing. The changes could be interpreted as a recovery from the Sahelian droughts during the 1970´s and 1980´s. However, there are currently large uncertainties as to which processes that have

Through WTO membership, a large number of countries are parties to the Agreement on Trade-Related Aspects of Intellectual Property Rights, also known as TRIPs. The strongest form of IP protection is the patent, which grants a number of valuable exclusive rights when the criteria for patentability have been met. Patents are often claimed to be a means for inventors to regain the expenses they may h

Capital movement in the world has great impact on economies. Remittances to developing countries are today seen as an important channel for economic growth in less developed countries (LDCs). The purpose of this thesis is to examine migration and remittances to and from the Philippines. Questions of particular interest are whether there are any patterns in migration or remittances in the Philippin

Sweden became a member of the European Union in 1995. Consequently Sweden became obligated to implement the Working Time Directive 2003/88/EC (formerly termed 93/104/EC). At that time Sweden considered that their legislation already gave their employees as high level of protection as the directive prescribed. Instead they decided upon an adjustment of the collective agreements concerning working t
