Granzyme B is known to be a serine protease contained in granules of cytotoxic T cells. We have previously reported an influence of granzyme B expression in T regulatory cells (Tregs) on the risk of acute graft versus host disease (GVHD) onset. However, it is still unknown if conventional T cells (Tcon) use the granzyme B pathway as a mechanism of alloimmunity. We hypothesized that granzyme B in Tcon may affect recurrence within the first 6 months after allogeneic transplantation (allo-HSCT). A total of 65 patients with different hematological malignancies were included in this study. Blood samples were collected on day +30 after allo-HSCT. The percentage of granzyme B positive conventional T cells in patients who developed relapse in the first 6 months after allo-HSCT was 11.3 (4.5-35.3) compared to the others in continuous complete remission-1.3 (3.65-9.7), р = 0.011. The risk of relapse after allo-HSCT was in 3.9 times higher in patients with an increased percentage of granzyme B positive conventional T cells. The findings demonstrated that the percentage of granzyme B positive conventional T cells on day +30 after allo-HSCT could be a predictable marker of relapse within the first 6 months after allo-HSCT. V.BACKGROUND The liver and renal capsule are the most common site for experimental pancreatic islet transplantation, but it is not optimal. Gastric submucosa space may be an ideal site for islet transplantation; however, whether pro-inflammation factors mediated islet dysfunction could be avoided or alleviated is still unclear. METHODS Islets of Sprague Dawley (SD) rat were transplanted into the streptozotocin-induced diabetic SD rats. Transplantation sites included gastric submucosa (GS), intraportal vein (PV) and kidney capsule (KC), and the efficiency of glycemic control and site-specific differences of islet grafts were compared. RESULTS With limited number of islets (800 IEQ) transplanted, improvement of recipient glycometabolism was superior in the GS group. When transplanted with 1200 IEQ islets, the survival of islet grafts were significantly prolonged in the GS group (25.87 ± 4.08 days, compared to 15.97 ± 0.83 days and 17.33 ± 1.41 days in PV and KC groups, respectively, P  less then  .05). Compared with the PV group, the levels of IL-1β and TNF-α were significantly depressed in GS group after 12 h transplantation (15.5 ± 0.70 pg/mL and 13.28 ± 2.80 pg/mL vs. 262.26 ± 53.37 pg/mL and 138.51 ± 39.58 pg/mL, P  less then  .05). CONCLUSIONS Gastric submucosal would be a potential ideal site for islet transplantation in rat. Gastric submucosal might alleviate the early islet dysfunction triggered by the IL-1β and TNF-α, and which requires a low number of transplanted islets and have a good glycemic control in return. V.OBJECTIVE This study aimed to assess the survival and success of glass fiber posts compared to cast metal posts in teeth without ferrule. MATERIAL AND METHODS An equivalency, prospective, double-blind (patient and outcome evaluator) randomized controlled trial (RCT) with parallel groups was designed to compare the clinical performance of cast metal and glass fiber posts cemented in endodontically treated teeth without ferrule (NCT01461239). Teeth were randomly allocated to the glass fiber or cast-metal post groups. All teeth were restored with single metal-ceramic crowns. Kaplan-Meier analysis with the log-rank test was used to test the success and survival between glass fiber and cast metal posts considering a cut-off value of P = 0.05. The annual failure rates were calculated considering the survival data for all restorations and separated by type of post after five years. RESULTS A hundred and nineteen patients and 183 posts (72 cast metal posts and 111 glass fiber posts) were analyzed. The median follow-up was 62 months (IQR 37-81). The log-rank test for success (P = 0.26) and survival (P = 0.63) analyses did not present statistically significant differences. The AFR of both posts after 5 years was 1.5%. Considering the posts separately and after 5 years, cast metal posts presented AFR of 1.2% and glass fiber posts AFR of 1.7%. Most failures were in posterior teeth (16/23), 10 failures were classified as root fractures and 5 as post debonding. The follow-up rate was 95.3%. CONCLUSIONS Glass fiber and cast metal posts showed good and similar clinical performance. CLINICAL SIGNIFICANCE Results of this randomized controlled trial can help dentists to answer how the best technique to rehabilitate endodontically treated teeth with no remaining coronal wall. Exosome associated Adeno-associated virus (AAV) vectors have emerged as a promising tool in gene therapy. Recently, we elucidated the role of SUMOylation post-translational modification in AAV2 capsid and demonstrated that capsid modifications at SUMOylation sites, enhance vector transduction. The present study was designed to study the combinatorial effect of exosome delivery of a SUMOylation site modified AAV2, during ocular gene therapy. In the first set of experiments, we investigated the in vitro gene transfer potential of exosome-associated SUMOylation mutant AAV2 (Exo-K105Q-EGFP) in human retinal pigmental epithelial (ARPE19) cells. Our data showed that, Exo-K105Q vectors had a significantly higher transduction potential in ARPE19 cells when compared to exosomes derived from wildtype AAV2 (Exo-AAV2-EGFP) vector packaging. Subsequently, an intravitreal administration of exosome associated mutant AAV2 vectors in C57BL6/J mice, demonstrated a significant increase reporter gene (EFGP) expression 4 weeks after gene transfer. Further immunostaining, revealed that these exosome-based vectors also had a better permeation across the retinal layers. These data highlight the translational potential of exosome associated SUMOylation mutant AAV for ocular gene therapy. The potential utility of RNA interference (RNAi) to control insect pests and viral infections depends largely on the target organism's ability to systemically spread the RNAi response. The efficacy of systemic RNAi varies among insects, though it has been shown to be high in the red flour beetle, Tribolium castaneum. We identified an extracellular RNAi signal that is present in the culture medium of T. castaneum (TcA) cells after treatment with long dsRNA specific for a luciferase reporter gene. Luciferase-specific siRNAs were detected in extracellular vesicles (EVs) that were purified from the culture medium of these dsRNA-treated cells. Furthermore, by measuring the silencing of luciferase expression, we showed that these siRNA-containing EVs can act as an RNAi signal for recipient TcA cells. We have therefore shown that a systemic RNAi response upon dsRNA treatment can be effectively spread through EVs. BACKGROUND The decision to attempt or refrain from resuscitation is preferably based on prognostic factors for outcome and subsequently communicated with patients. Both patients and physicians consider good communication important, however little is known about patient involvement in and understanding of cardiopulmonary resuscitation (CPR) directives. AIM To determine the prevalence of Do Not Resuscitate (DNR)-orders, to describe recollection of CPR-directive conversations and factors associated with patient recollection and understanding. METHODS This was a two-week nationwide multicentre cross-sectional observational study using a study-specific survey. The study population consisted of patients admitted to non-monitored wards in 13 hospitals. Data were collected from the electronic medical record (EMR) concerning CPR-directive, comorbidity and at-home medication. Patients reported their perception and expectations about CPR-counselling through a questionnaire. RESULTS A total of 1136 patients completed the questionnaire. Patients' CPR-directives were documented in the EMR as follows 63.7% full code, 27.5% DNR and in 8.8% no directive was documented. DNR was most often documented for patients >80 years (66.4%) and in patients using >10 medications (45.3%). Overall, 55.8% of patients recalled having had a conversation about their CPR-directive and 48.1% patients reported the same CPR-directive as the EMR. Most patients had a good experience with the CPR-directive conversation in general (66.1%), as well as its timing (84%) and location (94%) specifically. CONCLUSIONS The average DNR-prevalence is 27.5%. Correct understanding of their CPR-directive is lowest in patients aged ≥80 years and multimorbid patients. CPR-directive counselling should focus more on patient involvement and their correct understanding. The process of Ca2+ mediated gelation of alginate and the fabrication of nanoengineered polyelectrolyte capsules were combined for the preparation of alginate microbeads characterized by the presence of well-defined drug loaded microvoids in their volume. The obtained engineered alginate microbeads are described in terms of their morphology, loading efficiency and release characteristics. It was found that the generation of microvoids in the volume of alginate microbeads could be a promising approach for the creation of microstructured and biocompatible hydrogels, prospectively having highly tunable properties in terms of loading and releasing characteristics. In particular, it was found that the developed system was able to limit drug leakage during the gelation process and to control the initial burst release of small hydrophilic drug molecules, such as doxorubicin hydrochloride. Finally, the cytocompatibility of the developed microhydrogels was assessed on MCF-7 human breast cancer cells as well as their ability to sustain the release of the model drug during time. Panobinostat datasheet V.The aim of this work was to extract and characterize starch from three varieties of pigmented rice (named white, red and black), preserving the bioactive compounds. The extraction yield was 44.0%, 47.0% and 35.7%, respectively. The scanning electron microscopy showed that the granules of the three varieties presented polygonal and angular format and absence of impurities. The chemical analyzes, showed more than 83.0% of carbohydrates in the three compositions. There was retention of the phenolic compounds from the raw material in the starches. With regard to pasting properties of the starches, differences were observed in initial temperature, which was of 80.6 °C, 79.1 °C and 88.8 °C for the starches of white, red and black rice, respectively. Black rice starch also showed slightly higher crystallinity and thermal stability than white and red rice starches. Gels of red rice starch have higher syneresis in five freeze-thaw cycles, when compared to the others. Poria cocos (Polyporacea), is a fungus used in traditional Chinese medicine. A study of the valuable sulfated polysaccharides (SPS) with the structure and pharmaceutical benefits from the mycelial culture conditions of P. cocos was attempted. The SPSs were fractionated by gel filtration chromatography to give a fucose-containing mannoglucan polysaccharide (denoted as FMGP) The main skeleton was a 1,4-α-Man-interlaced-1,3-β-glucan with interlaced 6-O-α-l-fucosyl 1,4-α-Glc and 1,4-α-Gal branches. FMGP dramatically inhibited cell migration in the highly metastatic human lung cancer cell line CL1-5 cells. Mechanistically, FMGP dramatically downregulated the expression of TGFβRI and inhibited phosphorylation of FAK and AKT. Moreover, FMGP reduced the metastasis-related protein, Slug, expression. This is the first paper reporting a branched 1,3-β-mannoglucan from P. cocos and its anti-lung cancer CL1-5 cells migration activities. V.
