Late-onset bile leakage after hepatic resection.
Surgery
PUBLISHED: 01-17-2014
Show Abstract
Hide Abstract
Postoperative bile leakage can be a serious complication after hepatic resection. Few studies have analyzed patients according to the time of onset of bile leakage. We analyzed differences between patients with early- and late-onset bile leakage after hepatic resection and assessed clinical characteristics and outcomes in patients with late-onset leakage.

An improved process of isomaltooligosaccharide production in kimchi involving the addition of a Leuconostoc starter and sugars.

Hide Abstract
Isomaltooligosaccharides (IMOs) are ?-(1?6)-linked oligodextrans that show a prebiotic effect on Bifidobacterium spp. This study sought to improve IMO synthesis during lactate fermentation in kimchi by inoculating the kimchi fermentation mix with a starter and sugars; the psychrotrophic Leuconostoc citreum KACC 91035 strain with high dextransucrase activity was used as a starter and sucrose (58mM) and maltose (56mM) were added as the donor and acceptor for the glucose-transferring reaction of the dextransucrase, respectively. With the addition of both the starter and the sugars and incubation at 10°C, IMOs were produced in kimchi after 3d. Without the starter, the IMO production rate and maximal concentration in kimchi were 15.05mM/d and 75.27mM, respectively, whereas with the starter, the rate and concentration increased to 22.04mM/d and 110.19mM, respectively. In addition, the sucrose-maltose mix gave an appropriate level of sweetness by releasing fructose and prevented unfavorable polymer synthesis by IMO production. This result suggests that lactic acid bacteria expressing a highly active glycosyltransferase can be used for the synthesis of beneficial oligosaccharides in various fermented foods.

Posterior reversible encephalopathy syndrome in an untreated hypertensive patient after spinal surgery under general anesthesia -A case report-.
Korean J Anesthesiol
PUBLISHED: 05-31-2011
Show Abstract
Hide Abstract
Posterior reversible encephalopathy syndrome (PRES) is an unfamiliar term to anesthesiologists, and this is characterized by neurologic symptoms that include mental change, headache, seizure and visual disturbance and also abnormal neuroimaging finding. A 71-year-old female patient was operated on for posterior decompression and total laminectomy under general anesthesia for the spinal stenosis. After the operation, she developed generalized tonic-clonic seizure and a stuporous mentality in the recovery room. The magnetic resonance imaging (MRI) revealed swelling and increased signal intensity at the deep gray nuclei, cerebral cortex and cerebellum. After one week, she returned to an alert mentality and then she was diagnosed with PRES. She was discharged without any neurologic deficit on postoperative day 20. This report describes our experience with PRES after spinal surgery was performed under general anesthesia on a suspected untreated hypertensive patient.

Clinical usefulness of mitochondrial transcription factor A expression as a predictive marker in colorectal cancer patients treated with FOLFOX.

Hide Abstract
We previously reported that mitochondrial transcription factor A (mtTFA) preferentially recognizes cisplatin-damaged DNA via physical interaction with p53 and is upregulated by treatment with cisplatin and fluorouracil (5-FU). The aim of the present study was to evaluate whether expression of mtTFA predicts the clinical outcome in patients with metastatic colorectal cancer treated with modified 5-fluorouracil, leucovorin and oxaliplatin 6 (mFOLFOX6). Fifty-nine patients with metastatic lesions from colorectal cancer treated with mFOLFOX6 were included in this study. The subjects consisted of 25 women and 34 men with a median age of 62 years. The patients were treated with oxaliplatin (85 mg/m(2) ) plus leucovorin (200 mg/m(2) ) as a 2-h infusion on day 1, followed by 5-FU (400 mg/m(2) ) bolus and 46-h continuous infusion of 2400 mg/m(2) . The expressions of mtTFA and p53 of resected primary tumors were examined by immunohistochemical analysis. Of the 59 patients, 33 (complete response 1, partial response 32) achieved a confirmed response to therapy. The positive cytoplasmic staining rate for mtTFA was 44.1% and that for p53 was 59.3%, respectively. Strong expression of mtTFA was detected in eight of 33 complete response/partial response (24.2%) and in 18 of 26 SD/PD (69.2%), indicating that mtTFA expression was significantly correlated with response to chemotherapy (P<0.01). Median overall survival was significantly longer in patients without mtTFA expression (P=0.0493). Multivariate analysis revealed that mtTFA expression significantly affected overall survival (hazard ratio 2.10, P=0.036). Immunohistochemical study of mtTFA may be useful for predicting the clinical outcome of metastatic colorectal cancer patients treated with FOLFOX.

Synthesis and biological evaluation of 4(5)-(6-methylpyridin-2-yl)imidazoles and -pyrazoles as transforming growth factor-beta type 1 receptor kinase inhibitors.

Hide Abstract
A series of 4(5)-(6-methylpyridin-2-yl)imidazoles 16-19 and -pyrazoles 22-29, 33, and 34 have been synthesized and evaluated for their ALK5 inhibitory activity in an enzyme assay and in cell-based luciferase reporter assays. The 6-quinolinyl imidazole analogs 16 and 18 inhibited ALK5 phosphorylation with IC(50) values of 0.026 and 0.034 microM, respectively. In a luciferase reporter assay using HaCaT cells transiently transfected with p3TP-luc reporter construct, 18 displayed 66% inhibition at 0.05 microM, while competitor compounds 2 and 3 showed 44% inhibition. The binding mode of 18 generated by flexible docking studies with ALK5:18 complex shows that it fits well into the active site cavity of ALK5 by forming broad and tight interactions.

Production of recombinant human von Willebrand factor in the milk of transgenic pigs.

Show Abstract
Hide Abstract
Von Willebrand factor (vWF), a large multimeric glycoprotein present in blood plasma, is a blood protein of the coagulation system. It is defective in von Willebrand disease and is involved in a large number of other diseases, including thrombotic thrombocytopenic purpura-hemolytic uremic syndrome and heydes syndrome. We have developed a line of transgenic swine harboring recombinant human von Willebrand factor (rhvWF) cDNA through microinjection of fertilized one-cell pig zygotes. Expression of rhvWF in the mammary gland and secretion of rhvWF into the milk of the transgenic swine were confirmed by immunohistochemical and western blot analyses, respectively, and rhvWF proteins were detected in milk from all lactating founder females at concentrations that were 28- to 56-folds greater than that in circulating human plasma. The amino acid sequence of rhvWF protein in the transgenic pig milk matched that of vWF produced from human blood plasma. This study provides evidence that production of rhvWF from transgenic pig milk is a potentially valuable technology and can be used as a cost-effective alternative in clinical applications.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
