Dr. Dressel studies how specific drugs and technologies can improve health outcomes in various medical conditions. For instance, he investigates how gold nanoparticles can enhance the effectiveness of radiation therapy in cancer patients by causing more significant DNA damage to cancer cells. He also explores pharmacological advancements, such as the use of rivaroxaban, a blood thinner, to prevent blood clots in patients recovering from surgery. Additionally, he has conducted research on techniques like vacuum-assisted wound closure to manage deep infections after spinal surgery, improving healing without needing further invasive procedures. His work helps both human patients, particularly in oncology and surgical recovery, and veterinarians by understanding the effects of toxins on pets.
Key findings
Gold nanoparticles can predict where DNA damage occurs due to increased electron activity during radiation therapy, enhancing treatment effectiveness for cancer patients.
In a study on mice, higher doses of rivaroxaban (2.0 and 3.0 mg/kg) significantly improved blood flow and reduced clotting, suggesting it could help patients recover from vascular injuries.
Using vacuum-assisted wound closure (VAC) led to successful healing of deep infections in all 20 post-spinal fusion surgery patients within about 7 days, without serious complications.
In a study on pancreatic cancer versus chronic pancreatitis, doctors accurately identified conditions in 73% of cases analyzed, improving the diagnostic process for pancreatic issues.
Cytology improved the accuracy of ERCP for detecting pancreatic cancer from 73% to 85% when performed correctly, enhancing early diagnosis for patients.

Radiation protection dosimetry
Dressel T, Bug MU, Gargioni E, Rabus H
Plain English This study focused on how gold nanoparticles (tiny particles made of gold) affect cells when they are exposed to radiation. Researchers created a computer program that models how these nanoparticles cause DNA damage inside the cell nucleus, finding that the program can accurately predict where ionizations occur due to increased electron activity from the nanoparticles. This is important because it helps improve our understanding of how these nanoparticles can enhance radiation therapy for cancer treatment.

Thrombosis research
Wagner NM, Dressel T, Schäfer K, Konstantinides S
Plain English This study looked at how the drug rivaroxaban affects blood clot formation in mice with vascular damage. Researchers found that higher doses of rivaroxaban (2.0 and 3.0 mg/kg) significantly increased blood flow and reduced the amount of clotting in the arteries compared to mice that did not receive the drug. This is important because it suggests that rivaroxaban could help prevent dangerous blood clots in patients, improving their recovery after vascular injuries.
Who this helps: This benefits patients at risk for blood clots, such as those recovering from surgeries or injuries.

Plain English This study looked at how vacuum-assisted wound closure (VAC) can help patients who develop deep infections after spinal fusion surgery. Researchers followed 20 patients with these infections and found that using VAC, after cleaning the wounds, led to successful closure in all cases within about 7 days, with no serious complications. This is important because it shows that VAC can effectively manage complex infections, allowing patients to heal without needing to remove implanted devices.
Who this helps: Patients recovering from spinal surgery who experience deep wound infections.
Plain English This study looked at how the insecticide Diazinon affects the pancreas in dogs, cats, and guinea pigs. It found that while cats did not show any harmful effects from Diazinon, both dogs and guinea pigs developed serious pancreatic issues, such as swelling and inflammation, just two hours after exposure. Pretreating with atropine completely prevented these problems, highlighting the importance of a specific enzyme in protecting the pancreas from damage caused by the insecticide.
Who this helps: This research helps veterinarians and pet owners who need to understand and treat insecticide poisoning in pets.
Plain English This study examined the use of cytology, a method for analyzing cells, to help diagnose pancreatic cancer in patients undergoing a procedure called ERCP. Out of 26 patients confirmed to have pancreatic cancer, 54% had positive cytology results when the procedure was performed correctly. Using cytology alongside ERCP improved the test's accuracy from 73% to 85% for detecting cancer.
Who this helps: This aids doctors in accurately diagnosing pancreatic cancer, benefiting patients with suspected pancreatic diseases.
Clinical and secretory differences in pancreatic cancer and chronic pancreatitis.

Goodale RL, Condie RM, Gajl-Peczalska K, Taylor T, O'Leary J +4 more
Plain English This study looked at how to tell the difference between chronic pancreatitis and pancreatic cancer by analyzing medical tests in 60 patients. They found that doctors could correctly identify the conditions in 73% of cases using imaging studies like ERCP, which showed 80% sensitivity for detecting cancer. Notably, pancreatic cancer patients had significantly higher levels of certain proteins—specifically, albumin was more than ten times higher than in chronic pancreatitis cases, which might help develop better tests for diagnosing pancreatic cancer.
Who this helps: This helps patients with pancreatic issues by improving diagnostic accuracy for their condition.
