restrictions on the use of synthetic antioxidant such as butylated  hydroxyanisole  (bha) and butylated  hydroxytoluene (bht) are being imposed  because of  their carcinogecity. in this investigation  optimization  of phenolic extraction  process  frome  methanolic (80%)  extract (v/v) of  elaegnus  angustifolia  through  response  surface methodology  by fulin cio- calteu is  performrd  for op...

objective: this study presents an efficient, cost-effective method to improve proliferation and colonization of spermatogonial stem cells (sscs) in vitro. methods: isolated sscs from neonate mice were cultured in dmem culture medium with 10% fetal bovine serum (fbs). in the first phase of the study, the temperature was controlled by low intensity pulsed ultrasound stimulation (lipus) of the pla...

background in stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. objectives to determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (fast) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. patients and methods we performed a prospective obs...

Background: Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells; however, it can be used to destroy cancer cells as an efficient therapeutic method. On the other hand, it is known that the existence of nanoparticles in a liquid decreases the acoustic cavitation onset threshold. Materials and Methods: In this work, the combined effects of therape...

background : safe dose escalation is highly desirable in radiotherapy for prostate cancer. prostate displacement due to bladder filling can be significant, so improved targeting of the prostate by ultrasound imaging potentially allows for a reduction in the target margin and consequently less toxicity. this study estimates the accuracy of ultrasound for prostate and bladder volume measurements ...

purpose: to compare thickness of central cornea measured using pentacam, orbscan ii, and ultrasound pachymeter methods: patients with no history of corneal diseases or systemic diseases affecting eyes, who did not wear contact lens or use eye medications, and who with no previous history of corneal surgery were selected for this study. central corneal thickness (cct) was measured by three metho...

introduction: phonophoresis is the use of ultrasound to enhancing cellular drug delivery through the skin. in this study the effect of clobethasole and hydrocortisone ointments phonophoresis on pain, knee osteoarthritis and some other symptoms was studied. methods: an experimental single blind randomized clinical trial (rct) was used. an available sampling technique was used for selection of pa...

dermatofibrosarcoma protuberans is an uncommon malignant mesenchymal tumor of the dermis, which most commonly appears on the body and extremities. a preoperative diagnosis of dermatofibrosarcoma protuberans is extremely difficult, because it is a very rare entity and its appearance is often similar to that of benign breast lesion. here, we presented a case of breast dermatofibrosarcoma protuber...

hydatid cyst (hc) is a parasitic disease that may involve many organs, especially the lung and the liver. pulmonary artery location of the hydatid cyst is extremely rare, but it may cause life-threatening complications. we report a case of a hydatid cyst that completely filled the left main pulmonary artery and its distal part without cardiac involvement. thoracic computed tomography showed fil...

annular pancreas is a rare congenital condition of the pancreas where the pancreatic tissue either partially or completely covers the duodenum by forming a ring. endoscopic ultrasound is rarely considered as the first diagnosis tool for annular pancreas. we here present a 48 years old man who was primarily provisionally diagnosed with pancreatic mass and was planned for pancreatoduodenectomy. b...
