Article Synopsis
- The study examined the impact of Helicoverpa zea damage on maize, comparing Bt maize (which produces Cry toxins) and non-Bt maize across North and South Carolina from 2017 to 2019.
- Despite the presence of resistance to Cry toxins in maize, Bt maize showed significantly lower damage compared to non-Bt.
- A negative correlation was found between nearby maize abundance and damage levels, suggesting that the distribution of the moth population influences infestation rates in local maize crops.
Article Synopsis
- Genetically engineered Bt crops like maize and cotton have significantly reduced insecticide usage and targeted pest control, but there are concerns about pests evolving resistance.
- To counter resistance, the EPA mandates strategies such as planting a 20% refuge of non-Bt maize alongside Bt maize, while Bt cotton relies on diverse natural refuges.
- The study highlights that the effectiveness of these refuges in managing Helicoverpa zea pests is influenced by the local presence of Bt and non-Bt crops, stressing the need for careful consideration in pest management strategies.
Article Synopsis
- Gene expression in tissues is influenced by epigenetic, transcriptional, and post-transcriptional processes that determine cellular identity through protein production.
- A study identified DDX27, a DEAD-Box RNA helicase, as essential for growth and regeneration in skeletal muscle, suggesting its role in myogenesis.
- DDX27 is crucial for the maturation of ribosomal RNA, impacting ribosome biogenesis and the translation of specific genes in muscle development.
Mathematical models of tumor growth using Voronoi tessellations in pathology slides of kidney cancer.
Annu Int Conf IEEE Eng Med Biol Soc
August 2015
The impact of patient-specific spatial distribution features of cell nuclei on tumor growth characteristics was analyzed. Tumor tissues from kidney cancer patients were allowed to grow in mice to apply H&E staining and to measure tumor volume during preclinical phase of our study. Imaging the H&E stained slides under a digital light microscope, the morphological characteristics of nuclei positions were determined.

In these settings the problem is exacerbated by the lack of inexpensive media for the detection of E.
