Case report presents the successful treatment of unresectable liver metastasis in a patient with colon cancer. A 44-year-old male underwent right hemicolectomy followed by capecitabine for a moderately differentiated adenocarcinoma of the colon. 2 years later, a liver metastatic lesion was detected and had increased in size despite chemotherapy with capecitabine plus oxaliplatin (XELOX). Curative liver resection was conducted after conversion of unresectable tumor to resectable by transarterial chemoembolization followed by chemotherapy - irinotecan with fluorouracil and folinic acid (FOLFIRI)...

Brain hemorrhages are rare complications of acute methanol poisoning. There is a debate on association of brain hemorrhage in methanol toxicity and application of systemic anticoagulation during hemodialysis (HD). A 70-year-old male presented to us with severe metabolic acidosis and a methanol level of 7.6 mg/dL. Ethanol and folinic acid were administered, and HD was performed. Brain computed tomography (CT) scan which was normal on presentation showed extensive bilateral subcortical supratentorial hypodensities on the 3(rd) day after commencing the treatment...

Plant phenols may accumulate in end-stage kidney disease. The effect of hemodialysis on their plasma concentration remains poorly determined. Contingent on concentration, health-promoting or noxious effects occur; therefore, we assessed plasma concentration in hemodialyzed patients. In total, 21 maintenance hemodialyzed patients with diuresis < 500 mL per day (with oliguria), nine hemodialyzed patients with diuresis ≥ 500 mL per day (without oliguria) and 31 healthy volunteers were included. Nine phenolic acids were identified with high-performance liquid chromatography and total polyphenol concentration was determined with the Folin-Ciocalteu method in pre- or post-hemodialysis plasma and pre- or intra-hemodialysis dialysate...

REVIEW
Neha Goel, Sanjay S Reddy
The management of pancreatic cancer has grown rapidly in the last decade. The Gastrointestinal Tumor Study Group trial in 1985 supported postoperative chemoradiation, and a more recent study recommended 6 months of adjuvant gemcitabine and capecitabine or monotherapy with gemcitabine or fluorouracil plus folinic acid, in the absence of neoadjuvant therapy. Clinicians are now studying the role of targeted therapy in pancreatic cancer and neoadjuvant chemotherapy in resectable, borderline resectable, and locally advanced pancreatic cancer...

Pasta and couscous are popular foods manufactured (in their traditional form) from durum wheat semolina. In recent years, the consumers' quest for novel, functional, gluten-free, wholegrain foods has prompted the industry to manufacture new pasta and couscous products in which durum wheat has been partially or totally replaced by other vegetable flours. Besides dietary fibre, these raw materials might be an interesting source of phytochemicals. In this work, 16 commercial samples of pasta and four samples of couscous representative of the new products and made of refined and wholegrain flours of different species of cereals, pseudocereals and legumes were analysed for free, hydrolysable bound and total polyphenol content by means of the Folin-Ciocalteu procedure...

Charles E Deutch
Many fruits and vegetables undergo browning when they are cut and the tissue is exposed to the air. This is due to the activity of the enzyme polyphenol oxidase (PPO, EC 1.14.18.1) with endogenous substrates. In this laboratory experiment, students prepare slices of different varieties of apples and assess the rate of browning. They make a simple extract of the apple tissue and measure the activity of PPO using 3,4-dihydroxy-l-phenylalanine (l-DOPA) as substrate. They determine the protein concentration of the extract with the Bradford Coomassie Blue reagent and calculate the specific activity of PPO...

Cancer is as unique as the person fighting it. With the exception of a few biomarker-driven therapies, patients go through rounds of trial-and-error approaches to find the best treatment. Using patient-derived cell lines, we show that zebrafish larvae xenotransplants constitute a fast and highly sensitive in vivo model for differential therapy response, with resolution to reveal intratumor functional cancer heterogeneity. We screened international colorectal cancer therapeutic guidelines and determined distinct functional tumor behaviors (proliferation, metastasis, and angiogenesis) and differential sensitivities to standard therapy...
