Biodiversity is important for many ecosystem processes. Global declines in pollinator diversity and abundance have been recognized, raising concerns about a pollination crisis of crops and wild plants. However, experimental evidence for effects of pollinator species diversity on plant reproduction is extremely scarce. We established communities with 1-5 bee species to test how seed production o...

The hypothesis that the frequency distribution of indices of oxidative drug-metabolizing activity is different between patients with bladder cancer (n = 98) and age, sex-matched control subjects (n = 110) has been investigated. Urinary recovery ratios of debrisoquine and R/S ratios of mephenytoin have been measured in an 8-h urine sample after simultaneous administration of debrisoquine (10 mg)...

PURPOSE The objective of this study was to use gene expression profiling to identify novel biomarkers that are predictive of aggressive behavior in clear cell renal cell carcinoma (CCRCC). EXPERIMENTAL DESIGN Candidate genes were discovered using Human Genome U133 Plus 2 Arrays and validated on independent samples by quantitative reverse transcription-PCR (RT-PCR). Both the discovery and the ...

BACKGROUND SATB1 has been previously proposed as a key protein that controls the development and progression of breast cancer. We explored the potential of the SATB1 protein as a therapeutic target and prognostic marker for human breast cancer. METHODS We used aggressive (MDA-MB-231 and BT549) and nonaggressive (SKBR3 and MCF7) breast cancer cell lines to investigate the potential of SATB1 as...

  Honey bee sting is used in some societies as a treatment of inflammation in joint diseases such as arthritis. To investigate the effect of honey bee venom in reducing inflammation, we selected 30 male Wister rats which were divided in to 6 groups. Except group 1, all remaining groups received 0.5 ml of complete Freund’s adjuvant to induce arthritis. After 9 days, all animals that received adj...

The aim of the study was to estimate the impact of antibiotic doxycycline on the spring development of the bee colonies, worker bees’ bodies chemical composition, development of hypopharyngeal glands and some physicochemical parameters of honey. The experiment was conducted during the spring stimulating feeding at apiary of Research Center of Stockbreeding and Agriculture, Smolyan, Bulgaria. Tw...

Artificial Bee Colony algorithm is an optimization algorithm based on the intelligent behavior of honey bee swarm. This paper presents Bee Swarm Optimization intended to introduce chaotic sequences and psychology factor of emotion into the algorithm. We define two emotions Bees could have, positive and negative, and correspond to two reaction to perception respectively. For avoiding premature c...

abstract: mostly honey bee consumes pollen as fermented and fermentation improves foods biological value in some cases.  in this study we evaluate the nutritional effects of fermented diets on honey bee body protein and brood rearing in colonies. this experiment conducted on honey bee colonies with different diets in a completely randomized design with 6 treatments and 7 replicates for 50 days....

Bees, as the main pollinators of food crops, represent a critical natural resource which needs to be carefully exploited and managed. In recent years, however, destruction of bee's native habitats, infestations, and displacements of native bees by alien bee species have reduced and disturbed bee populations and this is already having considerable impact on global agriculture. A further concurre...
