    LASIK means Laser-Assisted in situ Keratomileusis, which is a refractive laser eye surgery done by opthalmologists to treat patients with astigmatism, myopia and hyperopia. This procedure results to less pain and faster healing period compared with other procedures like photorefractive keratectomy. With a successful LASIK surgery, a patient regains a healthy eyesight, and need not use corrective eye glasses or contact lenses.

    The procedure has three stages: the pre-operative stage where the patient’s cornea is examined to determine the area from which tissue will be removed; the operation proper where a flap of the corneal tissue is created to allow the surgeon to remodel the cornea with a laser; and the post-operative stage where the patient’s recovery is ensured by protective goggles and medications to avoid infections.

    新奇医薬品の設計と製造をする新戦術がニューヨーク州立バッファロー大学で開発された。ロジウムに基づく触媒1グラムで100グラムの医薬品が作れるのだ。このロジウム金属の触媒は金の10倍の値段である。薬品供給会社でしか入手はできない。

    この新しい合成戦術はガンや炎症、微生物疾患といった病気に反応する混合物から作られている。

    新方法は分子が単純構造からより複雑な薬品のような材料に形を変えるようにする。そこから生まれた混合物は鏡像型であるが、厳密な研究では有害な面もある反鏡像型とされている。

  • Predicting the Recurrence of Prostate Cancer

    pros.jpgPrior to treatment, prostate cancer patients undergo endorectal MR imaging of the prostate to predict whether the cancer will recur after going through treatment. MR images of the prostate that show extracapsular extension before the patient undergoes therapy is an indication that metastases is more likely to occur in the future. This means regular treatment might not totally eradicate the cancer, therefore other treatment options and preventive measures should be discussed with the health care professional.

    This study was presented in May 2007 at the American Roentgen Ray Society Annual Meeting in Orlando, Florida. The lead author was Antonio Wetphalen, MD.
