Transgenic Plants from Dr. Davis's Lab.


Day 1
Dr. George Davis shared photos of transgenic tomato plants from his laboratory. The top photo shows plants  at day 1 grown in iron deficient Hoagland's solution at pH 7.4. Iron was provided as 10 µM FeCl3/15 µM avenic acid. Sample 13 (the top plant) has been transformed with an iron/avenic acid transporter isolated from roots of iron starved oats. Avenic acid Sample 14 (the lower plant) is untransformed. The bottom photo shows the tomato plants at day 14. Note the iron deficiency chlorosis in new leaves in sample 14. Avenic acid is the phytosiderophore synthesized by oats. Our synthetic form was made by our colleague, Dr. Mark Stocksdale, Earlham College

Internship Experience for Medical Imaging Majors

BAHS medical imaging majors gained valuable experience with various imaging technologies  during internships at Geisinger Health System.   Intern Ashley Wilkins  reports: "I  have been able to see so much in the Radiology field. I have observed general diagnostic radiology, MRI, CAT scan, and ultrasound. I have seen x-rays of different body parts, especially of the chest. I have also seen numerous MRIs of the brain and spine and CAT scans of the chest and abdomen. Lastly, I have seen many pregnancy ultrasounds. My favorite part of the internship is being able to start learning early. I definitely recommend this internship to other students. It is a great way to become more familiar with the type of environment you will work in during your career. It is also  a jump start to your learning, because you get to see so much and you have the opportunity to ask questions. " Intern Xiang Liao states .  "I learned how to position patients, collimate ...

Heather Detwiler studies abroad in Australia

Image
Heather Detwiler , a B.S. Health Sciences major in the pre-accelerated nursing major, received a BU Professional Experience Grant to study abroad in Australia during the summer through at program at the University of Canberra.  She conducted research on the prevalence of concussions in youth populations in conjunction with the Australia Institute of Sport. Her work focused on the treatment and prevention of concussions in youth soccer players, a field that has not received much attention. Concussions are associated with long-term neurocognitive impairment. Australia has a higher prevalence rate for concussions among youth soccer players, perhaps since heading the ball during games and practices is allowed.  Heather's study compared the differences between youth soccer concussion treatment and prevention methods between Australia and the United States. During her stay in Australia, Heather had the opportunity to travel, visiting Melbourne, The Great Ocean Road, Canberra, Sydney...
