Applying nanotechnology to plant science requires efficient systems for the delivery of nanoparticles (NPs) to plant cells and tissues. The presence of a cell wall in plant cells makes it challenging to extend the NP delivery methods available for animal research. In this work, research is presented which establishes an efficient NP delivery system for plant tissues using the biolistic method. ...

background : endometrial cancer is the most common type of malignancy in female reproductive system and is the fourth common cancer after breast, lungs and colorectal cancers. our aim is to report epidemiology and frequency types of endometrial cancer and clinical staging and grading of this disease. methods : in this description and cross-sectional study, 75 patients with diagnosed endometrial...

objective(s): the purpose of the present study was to prepare and to evaluate a novel niosome as transdermal drug delivery system for propranolol hydrochloride and to compare the in vitro efficiency of niosome by either thin film hydration or hand shaking method. materials and methods: niosomes were prepared by thin film hydration (tfh) or hand shaking (hs) method. propranolol niosomes were pre...

Transfection efficiency was the primary goal for in vitro gene delivery mediated by nonviral gene carriers. Here, we report a modified gene transfection method that could greatly increase the efficiency of, and accelerate the process mediated by, 25 kDa branched polyethyleneimine and Lipofectamine™ 2000 in a broad range of cell strains, including tumor, normal, primary, and embryonic stem cells...

The effectiveness of supplementation programs is affected by the ability to reduce intake variation and to meet target supplement consumption. A review was made of factors affecting variation in individual animal consumption of supplement by grazing cattle and sheep, including supplement type and feeding method, animal dominance and social interactions, and forage availability. The effects of p...

In order to develop intellectual expertise, the student needs to learn how to perform sophisticated pattern identification, and how to employ effective study and test taking strategies. These cognitive requirements are complex and analytical, and formal instruction operates under challenging constraints. In order to help students succeed in their chosen field, we need to understand better how i...

BACKGROUND Currently, the rate of caesarean section has been substantially increased in developing and developed countries. To determine the factors causing such an increase, it is important to determine reasons for women to refuse vaginal delivery and preferring caesarean section. OBJECTIVES To determine Turkish women's attitudes and basal knowledge regarding vaginal delivery and caesarean s...

Differential reinforcement of alternative behavior (DRA) may result in rates of reinforcement that are impractical for caregivers to implement; therefore, recent research has examined methods for thinning reinforcer delivery during DRA. In this study, reinforcer delivery was thinned during DRA by restricting access to the participant's alternative response materials.
