The effect of adding a 21-aminosteroid, U74500A, and a Ca2+ antagonist, lidoflazine, alone and together to UW solution was assessed in a rat liver preservation model. Following preservation, the livers were reperfused using a closed circuit, and the release of hepatocellular enzymes (ASAT, ALAT, and LDH) into the perfusate was determined with increasing time. Both drugs reduced the amount of en...

Context The effect on survival of orbital evisceration on patients with paranasal sinus neoplasms has not been well established. Objective To review systematically the available literature concerning survival in patients who undergo surgery for paranasal sinus neoplasm with and without preservation of the eye. Data Source A retrospective meta-analysis of English and non-English articles using M...

to evaluate the effect of adding neoadjuvant chemotherapy to surgery and radiation therapy for locally advanced resectable oral cavity squamous cell carcinoma, 24 patients with t3 or t4a oral cavity squamous cell carcinoma were randomly assigned to surgery alone or docetaxel, cisplatin, and 5-fu (tpf) induction chemotherapy followed by surgery. all patients were planned to receive chemoradiothe...

BACKGROUND Although much is known about the mucosal damage that occurs after intestinal warm ischemia and reperfusion and its recovery, little is known about the effect of cold preservation and transplantation on the mucosa. We studied the electrophysiological, biochemical, and histological changes of the intestinal mucosa after preservation for 24 hr and subsequent transplantation. METHODS T...

Phosphate-buffered sucrose (PBSc) solution is effective for short-term hypothermic preservation of tissue during feline kidney transplantation. A high-molecular-weight polyethylene glycol (35,000 Da, PEG35) reportedly enhanced the protective effects against cold-induced tubular injuries in animal kidney transplantation models. We investigated the ability of PBSc solution containing PEG35 to pre...

PURPOSE The aim of this study was to radiographically and clinically compare the effect of extracellular matrix (ECM) membranes on dimensional alterations following a ridge preservation procedure. METHODS One of 2 different ECM membranes was applied during a ridge preservation procedure. A widely used ECM membrane (WEM; Bio-Gide, Geistlich Biomaterials, Wolhusen, Switzerland) was applied in t...

Successful preservation of tissue samples is a prerequisite for long field studies in remote areas. However, there is little published information concerning field preservation of marine invertebrate tissues for DNA analyses. This omission is significant because marine biodiversity is centered in the Indo-Pacific, where immediate DNA analysis is often impossible. Consequently, we used an assay ...

Oncofertility is gaining importance because of increasing cancer incidence, high survivorship, the need to provide a good quality of life to survivors and the desire of patients to preserve their fertility. Disseminating information about the effect of cancer and cancer treatment on fertility and the availability and effectiveness of fertility preservation techniques is critical. Gynaecologists...

We show the effects of uncertainty, ecological and economic irreversibility, and endogenous learning on land preservation decisions for species conservation. We compare the optimal decisions of three types of decision makers: an experimenting decision maker who recognizes the endogeneity of information, a real options decision maker who ignores the endogeneity but recognizes the future availabi...

During the last decade an increased incidence of infections and outbreaks attributed to foodborne viruses, in particular noroviruses (NoV), was observed world wide. The awareness of the presence of viruses on food emphasized the need to acquire knowledge regarding the effect of preservation methods upon viruses. Most foodborne viruses cannot be cultured in the laboratory, which hinders studies ...
