Organ dose is the absorbed radiation energy from ionizing radiation to an organ, divided by the organ mass. Organ doses of a patient cannot be measured directly in the patient, but their determination requires dose measurements in anthropomorphic patient models i.e. phantoms or Monte Carlo simulations. Monte Carlo simulations can be performed for example by using computational phantoms or patie...

The study's objective was to investigate the antibody responses and fetal maternal adverse effects of Sinopharm vaccine. A prospective study conducted in Gynaecology Department LUMHS Hospital Jamshoro, Hyderabad, Multan DG Khan from January 2021 2022. total 90 women were included who administered Sinopharm. 3/90 (3.3%) received shots 1st trimester, 56/90 (62%) 2nd trimester 31/90 (34%) 3rd trim...

Fetal sensitivity to radiation-induced health effects is related to gestational age, and it is highly dependent on fetal dose. Typical fetal doses from diagnostic radiology are usually below any level of concern. Although rare, significant fetal radiation doses can result from interventional medical exposures (fluoroscopically guided techniques), radiation therapy, or radiological or nuclear in...

introduction: it is well know that fetal distress is one of the important causes of fetus perinatal morbidity and mortality. in this study, we sought to evaluate the association between umbilical coiling index and fetal distress.material and method:this was a case- control study conducted on 90 term pregnant women. study group had fetal distress (abnormal fetal heart rate, meconium staining, ap...

BACKGROUND Preeclampsia and fetal growth restriction are major causes of perinatal death and handicap in survivors. Randomized clinical trials have reported that the risk of preeclampsia, severe preeclampsia, and fetal growth restriction can be reduced by the prophylactic use of aspirin in high-risk women, but the appropriate dose of the drug to achieve this objective is not certain. OBJECTIV...

BACKGROUND Measuring fetal drug concentrations is extremely difficult in humans. We conducted a study in pregnant sheep to simultaneously describe maternal and fetal concentrations of propofol, a common intravenous anesthetic agent used in humans. Compared to inhalational anesthesia, propofol supplemented anesthesia lowered the dose of desflurane required to provide adequate uterine relaxation ...
