We explored the use of support vector machines (SVM) in order to analyze the ensemble activities of 24 postural and focal muscles recorded during a whole body pointing task. Because of the large number of variables involved in motor control studies, such multivariate methods have much to offer over the standard univariate techniques that are currently employed in the field to detect modificatio...
This research portrays the influence of socio economic variables on output honey in Ikwuano Local Government Area (LGA) Abia State, Nigeria. Specific analytical techniques employed were descriptive statistics, Likert rating scale and multiple regression analysis involving linear, Cobb Douglass, semi log exponential functional forms. Result from characteristics shows that greater percentage male...
Dissecting diversity patterns of organisms endemic to Iberia has been truly challenging for a variety of taxa, and the Iberian honey bee is no exception. Surveys of genetic variation in the Iberian honey bee are among the most extensive for any honey bee subspecies. From these, differential and complex patterns of diversity have emerged, which have yet to be fully resolved. Here, we used a geno...
controversial immunomodulatory properties of bee venom (bv) have provided an appropriate field for more investigation. the aim of present research was to verify the effects of honeybee venom on matrix metalloproteinase activity and interferon production as well as cell proliferation in monocyte and fibroblast cell lines. the monocyte and fibroblast cell lines (k562, ht-1080, wehi-164) were used...
the aim of this research was to construct an equipped hive with the acquisition, communication and analysis systems to send images on-line, wirelessly. this system could be used to evaluate density of bee colonies and also work as bait box to eliminate bee pest, if necessary. in this study, two methods, optical flow and neighborhood gray-tone difference matrix, were used to determine hive condi...
b a ckground: diabetes is an important disease. this disease is a metabolic disorder characterized by hyperglycemia resulting from perturbation in insulin secretion, insulin action or both. honey bee venom contains a wide range of polypeptide agents. the principle components of bee venom are mellitin and phospholipase a2. these components increase insulin secretion from the β-cells of pancreas....
High annual losses of honey bees, as well as range reductions and local extinctions of wild and native pollinator species, are concerning because bees are important plant pollinators [1]. Approximately one-third of the typical Western diet requires bee pollination, and honey bees (Apis mellifera) are the primary pollinators of numerous food crops, including fruits, nuts, vegetables, and oilseed...
In the present study, we examined the potential symptomatic and/or disease-modifying effects of monthly bee venom injections compared to placebo in moderatly affected Parkinson disease patients. We conducted a prospective, randomized double-blind study in 40 Parkinson disease patients at Hoehn & Yahr stages 1.5 to 3 who were either assigned to monthly bee venom injections or equivalent volumes ...
In most terrestrial ecosystems, nitrogen (N) is the most limiting nutrient for plant growth. Honey bees may help alleviate this limitation because their feces (frass) have high concentration of organic nitrogen that may decompose in soil and provide inorganic N to plants. However, information on soil N processes associated with bee frass is not available. The objectives of this work were to 1) ...
