The Democratic governor and the Republican legislature have moved to shore up the individual market, but Minnesotans are leaving it in droves. About 167,000 residents bought individual coverage this year, compared with 270,000 in 2016. Premium hikes have been caused, in part, by the consolidation of providers.

Objective To examine the effect of backpack hip strap use on walking energy expenditure while carrying a loaded backpack. Background Previous studies have demonstrated that energy cost increases as the mass of the load carried increases. However, few investigations have focused on backpack carriage design. Methods Fifteen young, healthy, male subjects walked at a self-selected pace for 10 minutes in two backpack loading conditions: with a hip strap (strapped) and without a hip strap (nonstrapped). Oxygen consumption (VO2), rating of perceived exertion (RPE), respiratory exchange ratio (RER), and heart rate (HR) were monitored throughout each 10-minute trial...

A surprising number of U.S. cities have drinking water with unhealthy levels of chemicals and contaminants. The city of Jacksonville (Florida), the location for this study, owns the dubious distinction of being ranked among the worst major American cities in water quality according to water quality tests conducted between 2005 and 2009 by the Environmental Working Group (EWG). This report of toxic chemicals in the Jacksonville water supply generated considerable negative publicity and coincides with a frequent and common complaint among residents of foul-smelling water...

Green exercise, defined as physical activity in natural environments, might have positive effects on stress-related physiological measures. Little is known about the acute effects of green exercise bouts lasting longer than 60 min. Therefore, the aim of the present study was to analyze the acute effects of a three-hour green exercise intervention (mountain hiking) on stress-related physiological responses. Using a randomized crossover design, 42 healthy participants were exposed to three different conditions in a field-based experiment: outdoor mountain hiking, indoor treadmill walking, and sedentary control condition (three hours each)...

Frostbite is an injury caused by the freezing of tissue, causing varied levels of tissue damage and necrosis. Case reports have shown a positive effect of hyperbaric oxygen (HBO₂) in such injuries, in acute cases as well as delayed (up to 21 days) presentation with complications. In this case report we present the course of hyperbaric treatment of two patients (a brother and sister, age 58 and 62) who sustained frostbite injuries to both feet 28 days earlier while hiking in the Himalayas. They were initially treated in Nepal following local protocol; afterward their primary care in the Netherlands was managed by the Burn Centre at Maasstad Hospital in Rotterdam...

Dinghy sailors lean their upper body over the windward side of the boat ('hiking') to keep the boat's balance and maximise its speed. Sustaining the hiking position is essential for competitive performance and this study examined sport-specific differences of muscles relevant for hiking in elite sailors. Knee extensor muscle strength as well as trunk muscle strength, muscle endurance and muscle thickness were assessed in elite dinghy sailors (n = 15) and compared to matched, non-sailing controls (n = 15)...

Since its discovery in the early 70s, the 2 micron plasmid of Saccharomyces cerevisiae continues to intrigue researchers with its high protein-coding capacity and a selfish nature yet high stability, earning it the title of a 'miniaturized selfish genetic element'. It codes for four proteins (Rep1, Rep2, Raf1, and Flp) vital for its own survival and recruits several host factors (RSC2, Cohesin, Cse4, Kip1, Bik1, Bim1, and microtubules) for its faithful segregation during cell division. The plasmid maintains a high-copy number with the help of Flp-mediated recombination...

The depletion of fossil fuels and hike in crude oil prices were some of the main reasons to explore new alternatives from renewable source of energy. This work presents the impact of various bowl geometries on diesel engine with diesel and biodiesel samples. Three non-edible oils were selected, namely pumpkin seed oil, orange oil and neem oil. These oils were converted into respective biodiesel using transesterification process in the presence of catalyst and alcohol. After transesterification process, the oils were termed as pumpkin seed oil methyl ester (PSOME), orange oil methyl ester (OME) and neem oil methyl ester (NOME), respectively...

We aimed to assess lung fluid balance before and after gradual ascent to 5150m. Lung diffusion capacity for carbon monoxide (DLCO), alveolar-capillary membrane conductance (DmCO) and ultrasound lung comets (ULCs) were assessed in 12 healthy lowlanders at sea-level, and on Day 1, Day 5 and Day 9 after arrival at Mount Everest Base Camp (EBC). EBC was reached following an 8-day hike at progressively increasing altitudes starting at 2860m. DLCO was unchanged from sea-level to Day 1 at EBC, but increased on Day 5 (11±10%) and Day 9 (10±9%) vs...

The exploitation of high volume of geolocalized data from social sport tracking applications of outdoor activities can be useful for natural resource planning and to understand the human mobility patterns during leisure activities. This geolocalized data represents the selection of hike activities according to subjective and objective factors such as personal goals, personal abilities, trail conditions or weather conditions. In our approach, human mobility patterns are analysed from trajectories which are generated by hikers...

In France, there is a growing enthusiasm for outdoor sports and recreation. In the meantime, the risk of both severe and frequent injury associated with active pursuits in mountain areas is acknowledged. This paper tackles accidents related to mountain sports, with a focus on three critical activities: hiking, mountaineering and ski touring. The aim consists of estimating the actual number of accidents (whether they entailed deaths or injuries) in the three above-mentioned activities. In order to align the information collected, then provide estimations based on the reasoned crossing of these secondary data, we consulted and summarised all the databases available on the French territory...
