Selected work

First-author studies on diabetic wound healing, and a contribution to a series of medical equipment industry reports.

2026

Research

Platelet-rich plasma and laser therapy for diabetic wounds

This experimental study in rabbits with diabetes compared two wound treatments: platelet-rich plasma, which is prepared from blood, and low-level laser therapy, which uses low-power laser light. Each was used alone and in combination. All three treatment groups healed better than the untreated group. The full results are reported in the article.

Research

Laser therapy and stem cells for diabetic wounds

This experimental study in rabbits with diabetes examined two wound treatments: low-level laser therapy, which uses low-power laser light, and human stem cells taken from fat tissue (adipose-derived stem cells). Each was used alone and in combination. After 30 days, the wounds that received both treatments healed better, and the repaired skin was stronger.

This research was carried out in animals. Clinical studies in people would be needed to confirm the results.

Medical equipment

Contributing to analytical reports on the medical equipment industry

I contributed to approximately 25 analytical reports, prepared over two years and commissioned by the General Directorate of Medical Equipment at Iran’s Ministry of Health and Medical Education.

  • Respiratory and anesthesia masks, breathing and suction tubes, ventilators, and anesthesia machines
  • Hemodialysis, orthopedic, and ophthalmic consumables
  • Diagnostic kits
  • Catheters, IV cannulas, heparin locks, three-way stopcocks, and extension tubing
  • General laboratory equipment and operating-room lights
  • Chest drainage bottles, chest tubes, and feeding tubes
  • Electrocardiographs, exercise stress-testing equipment, and cardiac rehabilitation equipment

Five short activities on tissue engineering and medical equipment, for curious visitors and students.

Tissue engineering

Build a tissue

Tissue engineering combines cells, a scaffold, and biological signals to build tissue that can repair or replace damaged tissue. Add the three ingredients one at a time to build a tissue.

0 of 3 ingredients added

  1. Cells

    Cells are the building blocks of tissue. Researchers can guide stem cells toward becoming specific cell types, then grow them on a scaffold.

  2. Scaffold

    The scaffold is the structure cells grow on. It can be built from many materials, from proteins to plastics, and it also relays the signals that guide the cells.

  3. Donor scaffold

    Some scaffolds come from donor organs: the organ’s cells are removed, and the remaining collagen framework is used to grow new tissue.

  4. Signals

    Biologically active molecules, such as growth factors, act as signals. Each signal can start a chain of responses that shapes what happens to a cell.

Engineered tissue

Together, cells, a scaffold, and signals can form functional tissue. Artificial skin and cartilage are engineered tissues approved by the U.S. FDA; more complex organs are still a long way from being ready for patients.

How a wound heals

When the skin is wounded, the body repairs it in four stages. Move the slider to follow them.

  1. Hemostasis: stopping the bleeding

    The body first works to prevent further blood loss. This starts within half an hour of the injury and can take up to a few days.

  2. Inflammation: defending the wound

    The immune system goes on high alert to protect the wound from infection. This usually lasts several days.

  3. Proliferation: new tissue

    The body produces new, healthy tissue to fill the wound.

  4. Remodeling: long-term repair

    Building on the earlier stages, the body works toward lasting healing of the area. This starts in the early weeks and can take up to a year.

The life of a medical device

Medical equipment needs managing from the first plan until the day it leaves service. Step through the five stages.

Stage 1 of 5

  1. Needs assessment

    Identify and prioritize the devices a facility needs by comparing what it has with what its services, patients, staff, and budget require.

    Source

  2. Acquisition

    Plan the purchase, including its costs, and choose a device and accessories that meet the agreed requirements.

    Source

  3. Introduction into service

    After delivery, the device is installed, commissioned, acceptance-tested, and calibrated. It is then recorded in the equipment inventory, and staff are trained to use and look after it.

    Source

  4. Maintenance

    Planned inspections confirm the device works correctly and is safe for patients and staff. Preventive maintenance extends its life and reduces failures; corrective maintenance fixes faults.

    Source

  5. Retirement

    When a device becomes obsolete, unusable, or no longer needed, it is decommissioned: removed from its original use, either for another use or for disposal.

Repair or replace?

Deciding when a device should leave service is part of managing it. What would you do?

  • A new model of your ultrasound machine has just come out. Yours works well, and the supplier still services it.

  • The supplier no longer services a patient monitor, and no spare parts or local technical support are available.

  • A device has a safety problem that cannot be resolved.

  • Your unit has replaced an older device, but the old one is still safe and reliable.

Sort the equipment

The industry reports I contributed to covered eight categories of medical equipment. Can you put each item in the right one?

  • Microdrip set Surgical and infusion supplies
  • Suction tube Breathing and anesthesia
  • Orthopedic consumables Dialysis, orthopedic and eye consumables
  • Diagnostic kit Diagnostic kits
  • Heparin lock Catheters and IV lines
  • General laboratory equipment Lab equipment and operating-room lights
  • Chest tube Chest drainage and feeding tubes
  • Exercise stress-testing equipment Heart testing and rehabilitation

Quick quiz

Question 1 of 3

Tissue engineering combines which three ingredients?
According to NIBIB, which engineered tissues have been approved by the U.S. FDA?
In WHO guidance, what comes right after a medical device is acquired?

Myth or fact?

  • Low-level laser therapy works by heating the tissue.

  • Most stem cell treatments sold by clinics are approved by regulators.

  • Some scaffolds for new tissue are made from donor organs.

  • Diabetes can make some sores harder to heal.
