Hyperkalemia is a relatively common electrolyte abnormality that in serious cases can lead to life-threatening arrhythmias. There are a number of factors that can contribute to hyperkalemia, and in most cases some level of kidney failure is present. The management of hyperkalemia depends on the underlying cause and the level of potassium. This paper briefly examines the pathophysiological mechanis
The aqueous humor actively interacts with the trabecular meshwork (TM), juxtacanalicular tissue (JCT), and Schlemm's canal (SC) through a dynamic fluid-structure interaction (FSI) coupling. Despite the fact that intraocular pressure (IOP) undergoes significant fluctuations, our understanding of the hyperviscoelastic biomechanical properties of the aqueous outflow tissues is limited. In this study,
Importance: Identification and preservation of parathyroid glands (PGs) remain challenging despite advances in surgical techniques. Considerable morbidity and even mortality result from hypoparathyroidism caused by devascularization or inadvertent removal of PGs. Emerging imaging technologies hold promise to improve identification and preservation of PGs during thyroid surgery. Observation: This n
Soot, or black carbon (BC), aerosol is a major climate forcer with severe health effects. The impacts depend strongly on particle number concentration, size and mixing state. This work reports on two field campaigns at nearby urban and rural sites, 65gkm apart, in southern Sweden during late summer 2018. BC was measured using a single-particle soot photometer (SP2) and Aethalometers (AE33). Differ
We describe an entomological dual-band 808 and 980 nm lidar system which has been implemented in a tropical cloud forest (Ecuador). The system was successfully tested at a sample rate of 5 kHz in a cloud forest during challenging foggy conditions (extinction coefficients up to 20 km–1). At times, the backscattered signal could be retrieved from a distance of 2.929 km. We present insect and bat obs
Denmark is ranked among the top countries in the world according to the World Energy Council (WEC) energy trilemma criteria: energy security, energy equity, and sustainability. The small Scandinavian country is known for its wind power technologies and large-scale integration of wind power into the grid. Compared to wind power, combined heat and power (CHP) plants, district heating (DH) technologi
Anhängare av den cirkulära ekonomin lyfter fram den som en väg mot hållbarhet. Men de fysikaliska lagar som styr energi och material, avfallets sociala och tekniska komplexitet och hindren för att omsätta cirkulära principer i praktik väcker allvarliga frågor om den cirkulära ekonomins och de cirkulära affärsmodellernas förmåga att fasa ut linjäriteten, eliminera dess negativa miljöpåverkan och er
IMPORTANCE: Breast cancer (BC) is the second leading cause of cancer death in women, and there is a substantial disparity in BC mortality by race, especially for early-onset BC in Black women. Many guidelines recommend starting BC screening from age 50 years; however, the current one-size-fits-all policy to start screening all women from a certain age may not be fair, equitable, or optimal.OBJECTI
BACKGROUND & AIMS: Gallstones (cholelithiasis) constitute a major health burden with high costs related to surgical removal of the gallbladder (cholecystectomy), generally indicated for symptomatic gallstones. The association between gallstones and cholecystectomy and kidney cancer is controversial. We comprehensively investigated this association, considering age at cholecystectomy and time f
A decade ago, Matt Armstrong noted that the War on Terror set the scene for US public diplomacy (PD) to be heavily focused on security. Other countries have focused their PD on image promotion, relationship-building or cultural relations. As digital media practices have slowly been adopted by the majority of foreign ministries, the logics governing social and digital media have also been increasin
