Compared to polyphenols or even polysaccharides the antioxidant potential of oligosaccharides is still unexplored. The aim of the present work was provide an up-to-date, broad and critical contribution on the topic of antioxidant oligosaccharides. METHODS The search was performed by crossing the words oligosaccharides and antioxidant. Whenever possible attempts at establishing correlations between chemical structure and antioxidant activity were undertaken. RESULTS The most representative in vitro and in vivo studies were compiled in two tables. Chitooligosaccharides and xylooligosaccharides and their derivatives were the most studied up to now. The antioxidant activities of oligosaccharides depend on the degree of polymerization and on the method used for depolymerization. Other factors influencing the antioxidant strength are solubility, monosaccharide composition, the type of glycosidic linkages of the side chains, molecular weight, reducing sugar content, the presence of phenolic groups such as ferulic acid, and the presence of uronic acid, among others. Modification of the antioxidant capacity of oligosaccharides has been achieved by adding diverse organic groups to their structures, thus increasing also the spectrum of potentially useful molecules. CONCLUSION A great amount of high quality evidence has been accumulating during the last decade in support to a meaningful antioxidant activity of oligosaccharides and derivatives. Ingestion of antioxidant oligosaccharides can be visualized as beneficial to human and animal health.

This review aims at exhaustively addressing the extractive and analytical approaches that have been developed for the isolation and quantification of CBD. Recent updates on cutting-edge technologies were critically examined in terms of yield, sensitivity, flexibility and performances in general, and are reviewed alongside original representative results. As an add-on to currently available contributions in the literature, the evolution of novel, efficient synthetic approaches for the preparation of CBD, a procedure which is appealing for the pharmaceutical industry, is also discussed. Moreover, given the increasing interest on the therapeutic potential of CBD and the limited understanding of the undergoing biochemical pathways, the reader will be updated about recent in silico studies on the molecular interactions of CBD towards several different targets attempting to fill this gap. Computational data retrieved from the literature have been integrated with novel in silico experiments, critically discussed to provide a comprehensive and updated overview on the undebatable potential of CBD and its therapeutic profile.

Therefore, JNKs represent new and excellent target by therapeutic agents. Many JNK inhibitors based on different molecular scaffolds have been discovered in the past decade. However, only a few of them have advanced to clinical trials. The major obstacle for the development of JNK inhibitors as therapeutic agents is the JNK-isoform selectivity. In this review, we describe the recent development of JNK inhibitors including ATP competitive and ATP non-competitive (allosteric) inhibitors, bidentate-binding inhibitors and dual inhibitors, the challenges, and future direction of JNK inhibitors as potential therapeutic agents.

It remains controversial whether shuntinterventions during liver transplant improve transplant outcomes. MATERIALS AND METHODS We conducted a retrospective comparison between deceased-donor liver transplant recipients who received spontaneous splenorenal shunt intervention and those who did not at a tertiary center between 2012 and 2017. Primary outcomes of interest included intraoperative transfusion requirement, hospital length of stay, acute kidney injury posttransplant, portal vein thrombosis, thrombocytopenia, and 1-year graft and patient survival. RESULTS Of 268 liver transplant recipients, 50 (18.6%) had large spontaneous splenorenal shunts pretransplant, with 45 patients having available radiologic and outcome data. Nine of 45 patients (20%) received shunt intervention, including pretransplant balloonoccluded retrograde transvenous obliteration (n = 5), intra intervention, spontaneous splenorenal shunt predominantly persisted 1 year posttransplant.Patients with glycogen storage diseases pose unique management challenges to clinicians.These challenges are exacerbated wheneverthey undergo surgery as the basic anomaly in their glycogen storage pathways make them susceptible to organic acidosis, which may in turn complicate their preoperative, intraoperative, and postoperative course. Because of the rarity of these diseases, clinicians may not be aware of the specific management concerns. In the case reported here, a 37-year-old patient with glycogen storage disease type 1 underwentleft hepatectomy for hepatic adenomatosis, which was complicated by intraoperative severe lactic acidosis that was successfully treated. link2 After successful hepatectomy, the patient underwent liver transplant without major lactic acidosis or hemodynamic instability. Early recognition and aggressive management of blood sugar and lactic acidosis in patients with glycogen storage diseases can allow for successful outcomes even when complex surgical procedures are required.OBJECTIVES Overall, 25% to 33% of patients on kidney transplant wait lists present with prior graft loss. In addition, the number of patients who require a retransplant seems to be increasing. Here, we describe our experience with patients who had a second kidney transplant after a previous pancreas-kidney transplant or a third or fourth kidney transplant. link3 We focused specifically on the technical aspects and outcomes related to this patient group. MATERIALS AND METHODS A single-center retrospective study was performed. The cohortincluded 15 patients > 18 years old who had received a second kidney graft after pancreas-kidney transplant or a second or greater kidney graft between 2013 and 2019. RESULTS Median age of recipients was 45 years (range, 20-58 y). In 10 patients, the transperitoneal approach was selected. In 5 patients, the retroperitoneal heterotopic kidney retransplant technique was used. Early surgical complications (≤ 30 days posttransplant) were reported in 4 patients. Three patients had late ureteral stenosis (> 90 days posttransplant). All grafts were functioning at time of patient discharge. Mean creatinine level was 2.69 mg/dL (range, 1.23-6.26 mg/dL). The 1-year and 2-year graft survivalrates were 85% and 75%, respectively. No grafts were lost because of surgical complications. CONCLUSIONS Retransplant of a second graft after pancreas-kidney transplant or retransplant of a third or fourth renal graft is challenging but feasible, with evidence of reasonably positive outcomes after retransplant.OBJECTIVES This study investigated the efficacy of ledipasvir-sofosbuvir, a newly developed direct-acting antiviral drug combination for hepatitis C virus infection recurrence in patients who have developed cirrhosis secondary to hepatitis C virus and who have undergone liver transplant. MATERIALS AND METHODS We retrospectively analyzed 27 patients who underwent liver transplant due to hepatitis C virus-related cirrhosis and who received ledipasvir-sofosbuvirfor 12 weeks between January 1, 2016 and December 31, 2017 following transplant procedures conducted at the Inonu University Turgut Ozal Medical Center Gastroenterology Department between January 1, 2008 and December 31, 2017. None of the donors had hepatitis C virus infection. Most donor grafts used in transplants were from children of recipients, with the remaining donated grafts from husbands (7%), nephews (4%), wives (7%), and deceased donors (7%). RESULTS Twenty patients were ultimately included in the study. Hepatitis C virus genotypes, hepatitis C virus RNA, blood counts, and liver enzyme levels of patients before and at 1, 2, and 6 months after treatment were evaluated. At the end of month 6, in addition to hepatitis C virus RNA levels of all patients decreased to unmeasurable levels, levels of alanine and aspartate aminotransferase and gamma-glutamyltransferase had also significantly decreased (all P less then .001). None of the patients experienced a complication that led to cessation of treatment. CONCLUSIONS With its reliability and high success rate, the ledipasvir-sofosbuvir combination is a strongly preferable treatment for patients who have undergone liver transplant due to chronic hepatitis C virus-related cirrhosis and who have virus recurrence posttransplant.The management of portosystemic shunts in liver transplant recipients relies on appropriate perioperative study. There are several strategies for shunt handling, ranging from preoperative interventional procedures to intraoperative surgical interruption or embolization. Appropriate management often results in a successful outcome, although wrong decisions could lead to serious consequences. Here, we report a liver transplant recipient with grade 2 portal vein thrombosis associated with 2 large portosystemic shunts (coronary and mesocaval), which were managed intraoperatively via thrombectomy without shunt ligation. Acute portal vein thrombosis developed early after transplant due to portal steal syndrome. The patient underwent a successful endovascular shunt embolization, with prompt restoration of hepatopetal portal flow and resolution of the portal steal. Use of interventional radiology in perioperative management of transplant patients has recently gained wider importance; our case reported here is particularly suggestive of the good outcomes of a multidisciplinary approach to a threatening complication such as postoperative acute portal vein thrombosis.The treatment of multiple myeloma (MM) continues to evolve with the approval of numerous agents over the past decade. Advances in treatment have led to the incorporation of these newer therapies into the treatment paradigm, with improvements in overall survival and the possibility of deep responses including a minimal residual disease-negative state. The strategy of triplet therapies for patients with newly diagnosed MM, followed by high-dose chemotherapy and autologous stem-cell transplantation for eligible patients, and subsequently consolidation and maintenance therapy, is the current treatment roadmap for patients. However, patients with MM will ultimately develop refractoriness to antimyeloma therapies. In this article, we summarize our current practice of managing patients with MM. We highlight our approach to patients with newly diagnosed MM who are transplantation eligible and ineligible and highlight risk-adapted strategies for these patients. In addition, we discuss our approach to the management of patients with relapsed or refractory MM.
