In Western societies the last several years, practicing yoga has really become fashionable and moved from being an auxiliary way to stretch and meditate to being the go to way to improve strength, flexibility, not to mention the positive affective aspects as well. The aim of the present short communication is to highlight the impact yoga has on different areas pertaining quality of life in the elderly population, especially regarding the risks concerning falling.
Az írás azt szemlélteti, hogy miképp lehetséges és érdemes a közigazgatást közgazdasági elemzésekben definiálni és modellezni. A felvázolt rendszer nyilvánvalóan nem képes a köziigazgatás cselekvési terében tajló összes jelenséget megmagyarázni; elsődleges funkciója az, hogy "előkészítse" a vizsgálati tárgyat (a közigazgatást) további elemzések (elsősorban a mérés) számára. A cikk végkövetkeztetése, hogy bizonyos nézőpontból a közigazgatás nem speciális vizsgálati tárgy, és rengeteg felhalmozott tudás és közgazdasági, mérési eszköz áll a rendelkezésünkre ahhoz, hogy jobban megértsük a működését - ugyanakkor az ismeretek inkább elaprózva, szétszórva találhatók meg az irodalomban.

Colorado potato beetle (Leptinotarsa decemlineata, Say) is the main pest of Solanaceae and its survival is mainly dependent on the carbohydrate digestion. Characterizing the gut enzymes may help us with finding effective inhibitors for plant protection. Activity measurements revealed that gut extracts contain α- and β-glucosidase in addition to α-amylase. For larvae, amylase activity was detected only in gut saturated with nutrients. Leptinotarsa decemlineata α-amylase (LDAmy) had optimum pH of 6.0 and was active under 30–40°C temperature measured on a selective α-amylase substrate, 2-chloro-4-nitrophenyl-4-O-α-D-galactopyranosyl-maltoside. HPLC analysis demonstrated dimer, trimer, and tetramer reducing end amylolytic products from 2-chloro-4-nitrophenyl-maltoheptaoside substrate in similar ratio than that of during porcine pancreatic α-amylase (PPA) catalyzed hydrolysis. The 4,6-O-benzylidene-modified substrate (BzG7PNP) is very stable toward hydrolysis by exo-glycosidases, therefore is very useful to monitor the digestion catalyzed by α-amylases exclusively. Similarly to PPA active site, three glycon and two aglycon binding sites are suggested for LDAmy based on the pattern of early hydrolysis products of BzG7PNP. The observed similarity between LDAmy and PPA raises the possibility of using known inhibitors of mammalian α-amylases to protect the potato plant from attack of Colorado potato beetle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
