Andersson1,2, Per Frank1,3, Marjan Pont&#233;n1, Bj&#246;rn Ekblom1, Maria Ekblom1,2, Marcus Moberg1, Kent Sahlin11<a href='/institutions/EU-Europe/SE-Sweden/25627-The-Swedish-School-of-Sport-and-Health-Sciences,-GIH'>&#197;strand Laboratory of Work Physiology, The Swedish School of Sport and Health Sciences, GIH</a>, 2<a href='/institutions/EU-Europe/SE-Sweden/977-Karolinska-Institutet'>Department of Neuroscience, Karolinska Institutet</a>, 3<a href='/institutions/EU-Europe/SE-Sweden/977-Karolinska-Institutet'>Department of Physiology and Pharmacology, Karolinska Institutet</a>The effect of short-term resistance training on elderly people was investigated through the simultaneous use of several methods. Compared to a control group, many improvements were seen, including on muscle aerobic capacity, glucose tolerance, strength, power, and muscle quality (i.e., protein involved in cell signaling and muscle fiber type composition).<h2 class="jove_title"><a href="https://www.jove.com/video/55605">Extraction and Purification of Polyphenols from Freeze-dried Berry Powder for the Treatment of Vascular Smooth Muscle Cells In Vitro</a></h2>Rafaela G.

jove monthly highlights: july 2017

Here's a look at what's coming up in the July 2017 issue of <a href="https://www.jove.com/">JoVE: The World's Premier Video Journal</a>
Summer fruits are our first video-appetizer this month, specifically, berries. Publishing in <a href="https://www.jove.com/biology">JoVE Biology</a>, <a href="https://www.jove.com/video/55605/extraction-purification-polyphenols-from-freeze-dried-berry-powder">our Authors</a> present a method for extracting polyphenols from freeze-dried blackberry and raspberry powder. Polyphenols have demonstrated antioxidant, anti-Inflammatory and cardio-protective properties. After extraction utilizing ethanol and sonication, our authors investigate the effects of both crude and purified extracts on cultured Vascular Smooth Muscle Cells. This extraction method can be applied to a wide variety of fruits and vegetables, and that's berry cool!
Eating healthily pairs with working out as we move to our second video highlight this month, from <a href="https://www.jove.com/chem">JoVE Chemistry</a>. Here, <a href="https://www.jove.com/video/55518/improving-strength-power-muscle-aerobic-capacity-glucose-tolerance">our Authors</a> describe a short-term resistance-training program focusing the elderly. The group used an isokinetic dynamometer to obtain detailed information on changes in strength and power, muscle biopsies to assess aerobic capacity, and monitored changes in glucose tolerance. They conclude that strength training in seniors may be more efficient and less physically stressful than endurance exercise for combatting common age related issues like diabetes, and reduce the risk of injury.
At the opposite end of the health spectrum our next study, from <a href="https://www.jove.com/neuro">JoVE Neuroscience</a>, looks at anti-smoking media. <a href="https://www.jove.com/video/55872/electroencephalographic-heart-rate-galvanic-skin-response-assessment">Our Authors</a> examined the emotional and cerebral reactions of subjects towards a selection of Public Service Announcements, or PSA's, aired in the USA and Europe between 1998 and 2015. Using a combination of electroencephalography, heart rate monitoring, and galvanic skin response, the researchers measured the physical and emotional effects of the commercials on the participants to gauge their effectiveness. These data may be used to design more effective PSA's in the future, and help reduce the number of current and new smokers.
All eyes are on a cool new technological application for our final highlight this month. In <a href="https://www.jove.com/med">JoVE Medicine</a>, <a href="https://www.jove.com/video/55958/smartphone-fundus-photography">our Authors</a> describe a simple method to record images of the ocular fundus using a smartphone camera and a conventional, hand-held ophthalmoscopy lens. This snappy trick allows clear documentation of macula and optic nerve changes in settings not previously available due to the lack of access to a professional fundus camera. I think we can all see how smart that is!
