Eisenmenger syndrome during pregnancy: A true anesthetic challenge.

Eisenmenger syndrome (ES) is a rare congenital heart disease (CHD) that occurs in persons with large intracardiac anatomical defects which may go undetected for many years, consequently results in reduced life expectancies and high mortality in the third and fourth decade of life. Pregnancy in patients with CHD and pulmonary arterial hypertension (PAH) is presaged with challenges, and perioperative management of such cases remains a topic of debate. Our case had both, atypical presentation, not diagnosed until her third trimester of third pregnancy and a quick progression to a severe stage with PAH and CorPulmonale.

Uracil derivatives as HIV-1 capsid protein inhibitors: design, , and cytotoxicity studies.

A series of novel uracil derivatives such as bispyrimidine dione and tetrapyrimidine dione derivatives were designed based on the existing four-point pharmacophore model as effective HIV capsid protein inhibitors. The compounds were initially docked with an HIV capsid protein monomer to rationalize the ideas of design and to find the potential binding modes. The successful design and computational studies led to the synthesis of bispyrimidine dione and tetrapyrimidine dione derivatives from uracil and aromatic aldehydes in the presence of HCl using novel methodology.

Clinical doses production of pharmaceutical grade Sodium[F]Fluoride using modified integrated fluidic processor in a SYNTHERA® module.

A fully automated large-scale production of sodium [F]fluoride ([F]NaF) using SYNTHERA module with a modification in integrated fluidic processor (IFP) is reported. This modified IFP module is used to prepare [F]NaF with more than 98% non-decay corrected radiochemical yield (RCY) within 5 min with specifications in accordance with United State Pharmacopeia (USP) monograph. The graphical user interface (GUI) is designed to perform the synthesis steps either manually or automatically and give information to the operator during the course of production.

Clinical Efficacy of Sodium [99mTc] Pertechnetate from Low Specific Activity 99Mo/99mTc Autosolex Generator in Hospital Radiopharmacy Centre.

Background: Few nuclear reactors in the world producing high specific activity (HSA) 99Mo using enriched 235U (HEU), are aging and are planned for shut down in the near future. Further, HEU will not be freely available, due to safeguards, and the technology for 99Mo from low-enriched 235U (LEU) is not yet widely accepted since 239Pu contamination in the product is an issue. Production of 99mTc from low specific activity (LSA) 99Mo obtained from 98Mo(n,)99Mo reaction in research reactor and 100Mo(,n)99Mo reaction in accelerator or directly from 100Mo(p,2n)99mTc nuclear reaction in cyclotron, has been explored [1].

A Comparative Study of Four Oral Contrast Agents for Small Bowel Distension with Computed Tomography Enterography.

Purpose: To assess the efficacy of a variety of oral contrast agents in obtaining small bowel distention for computed tomography (CT) enterography examinations.

Methods: A retrospective study was developed to quantitatively assess small bowel luminal distension during CT enterography by using 4 contrast agents, which included water, Metamucil, polyethylene glycol, and lactulose. A total of 256 patients were enrolled in the study and included 64 individuals for each oral regimen.

A computerized compact module for separation of (99m)Tc-radionuclide from molybdenum.

An automated closed cycle module for the separation and recovery of various isotopes, radioactive or non-radioactive, using solvent extraction and column chromatography techniques, and in particular, for separation and recovery of (99m)Tc from low-medium specific activity (99)Mo, is described. The module may also be applicable for separation of (99m)Tc produced in a cyclotron. The module is safe and reliable to avoid human interference and hazards posed by handling of radioactive and hazardous chemicals.

A comparison of radiation exposure with the conventional versus mini C arm in orthopedic extremity surgery.

Background: The mini C arm is a mobile fluoroscopic device for use on extremities. It has been reported that this type of device has several advantages over a conventional C arm, the most important of which is a decreased level of radiation scatter to the surgeon.

Methods: This was a case control study.
