BACKGROUND Poly (ADP-ribose) polymerase (PARP) inhibitors are extensively studied and used as anti-cancer drugs, as single agents or in combination with other therapies. Most radiotracers developed to date have been chosen on the basis of strong PARP1-3 affinity. Herein, we propose to study AZD2461, a PARP inhibitor with lower affinity towards PARP3, and to investigate its potential for PARP targeting in vivo. METHODS Using the Cu-mediated 18F-fluorodeboronation of a carefully designed radiolabelling precursor, we accessed the 18F-labelled isotopologue of the PARP inhibitor AZD2461. Cell uptake of [18F]AZD2461 in vitro was assessed in a range of pancreatic cell lines (PSN-1, PANC-1, CFPAC-1 and AsPC-1) to assess PARP expression and in vivo in xenograft-bearing mice. Blocking experiments were performed with both olaparib and AZD2461. RESULTS [18F]AZD2461 was efficiently radiolabelled via both manual and automated procedures (9 % ± 3 % and 3 % ± 1 % activity yields non-decay corrected). [18F]AZD2461 was taken up in vivo in PARP1-expressing tumours, and the highest uptake was observed for PSN-1 cells (7.34 ± 1.16 %ID/g). In vitro blocking experiments showed a lesser ability of olaparib to reduce [18F]AZD2461 binding, indicating a difference in selectivity between olaparib and AZD2461. CONCLUSION Taken together, we show the importance of screening the PARP selectivity profile of radiolabelled PARP inhibitors for use as PET imaging agents.PURPOSE Ileal transposition (IT) allows exploration of hindgut effects of bariatric procedures in inducing weight loss and reducing adiposity. Here we investigated the role of dietary macronutrient content on IT effects in rats. METHODS Male Lewis rats consuming one of three isocaloric liquid diets enriched with fat (HF), carbohydrates (HC), or protein (HP) underwent IT or sham surgery. Body weight, energy intake, energy efficiency, body composition, and (meal-induced) changes in plasma GIP, GLP-1, PYY, neurotensin, and insulin levels were measured. RESULTS Following IT, HC intake remained highest leading to smallest weight loss among dietary groups. IT in HF rats caused high initial weight loss and profound hypophagia, but the rats caught up later, and finally had the highest body fat content among IT rats. HP diet most efficaciously supported IT-induced reduction in body weight and adiposity, but (as opposed to other diet groups) lean mass was also reduced. Energy efficiency decreased immediately after IT irrespective of diet, but normalized later. Energy intake alone explained variation in post-operative weight change by 80%. GLP-1, neurotensin, and PYY were upregulated by IT, particularly during (0-60 min) and following 17-h post-ingestive intake, with marginal diet effects. Thirty-day post-operative cumulative energy intake was negatively correlated to 17-h post-ingestive PYY levels, explaining 47% of its variation. CONCLUSION Reduction in energy intake underlies IT-induced weight loss, with highest efficacy of the HP diet. PYY, GLP-1, and neurotensin levels are upregulated by IT, of which PYY may be most specifically related to reduced intake and weight loss after IT.PURPOSE Postoperative pain after laparoscopic surgery has 3 components parietal, visceral, and associated with pneumoperitoneum. Visceral pain accounts for around 30% of the total pain and is less amenable to be controlled by multimodal analgesia. The topical application of vitamin E ointment has demonstrated an anti-inflammatory effect in the local inflammatory response against surgical aggression. Vitamin E has been also associated with a reduction in postoperative pain of skin wounds. The aim of this study was to evaluate the effect of the topical application of vitamin E acetate on staple lines and anastomoses of Roux-en-Y gastric bypass, as part of a multimodal analgesia scheme within an Enhanced Recovery After Surgery (ERAS) program. METHODS A prospective randomized clinical trial was performed. SBP-7455 Patients were divided into 2 groups patients receiving a topical application of vitamin E on staple lines and anastomoses (G1) and patients not receiving it (G2). The primary endpoint was postoperative pain, as measured by VAS 24 h after surgery. Secondary outcomes include morphine rescue needs, acute phase reactants 24 h after surgery, and hospital stay. RESULTS One hundred forty patients were included, 70 in each group. Postoperative pain was 10 mm in G1 and 21.8 mm in G2 (p  less then  0.001). Morphine needs within the first 24 h were 2.9% in G1 and 13.2% in G2 (p = 0.026). C-reactive protein levels were significantly lower in G1 (8.7 mg/dL vs 11.9; p = 0.016). Mean hospital stay was 2.1 days in G1 and 2.9 in G2 (p = 0.019). CONCLUSION Topical application of vitamin E reduces postoperative pain and acute phase reactants, allowing an earlier discharge.

Taking the village as an administrative unit, the ecological safety and health risks of heavy metals, namely, Cr, Cu, Zn, and Pb in soils in the Houzhai River Watershed of Guizhou Province, China, were evaluated based on land use types by the Hakanson potential ecological risk methods and human health risk model. Results showed that the spatial heterogeneity of Cu and Zn was greatly affected by primary structural factors, and Cr and Pb were interfered by both structural factors and human activities. The geo-accumulation index of the heavy metals showed a light pollution in the study area. The comprehensive potential ecological risk of heavy metal in the area was divided into three levels slight, moderate, and intense, and it is spatially high in the northwest and low in the southeast. Both non-carcinogenic risk and carcinogenic risk of the heavy metals to the human body are not significant and are acceptable. The risks of children are higher than adults, and direct intake is the primary route of exposure in the area. The potential ecological risk and human health risk of soil heavy metals are relatively obviously affected by digital elevation data and normalized vegetation index. The study has certain reference value for the prevention and control of regional soil heavy metal risk.Background Elevated blood concentration of tacrolimus is frequently observed following transfusion of red blood cell concentrate in patients after allogeneic hematopoietic stem cell transplantation. Objective The aim of this retrospective study was to clarify the effects of transfusion of red blood cell concentrate on the blood concentration of tacrolimus. Setting Chiba University Hospital in Japan. Method Fifty-two patients (aged 0-65 years) receiving both tacrolimus and transfusion after allogeneic hematopoietic stem cell transplantation were enrolled. The ratio of measurement after transfusion to measurement before transfusion was calculated for hematocrit and blood concentration/dose ratio of tacrolimus (termed the hematocrit ratio and the tacrolimus ratio, respectively). Main outcome measure Change in blood concentration/dose ratio of tacrolimus and variable factors associated with variation in tacrolimus ratio. Results The blood concentration/dose ratio of tacrolimus was increased after transfusion compared with before transfusion (p  less then  0.001). A statistically significant correlation was seen between the hematocrit ratio and tacrolimus ratio (r = 0.32, p  less then  0.001). Hematocrit ratio, age or body surface area, and difference in aspartate aminotransferase level before and after transfusion were associated with the variation in tacrolimus ratio. There was no correlation between tacrolimus ratio and change in serum creatinine or potassium level in the short term. Conclusion Change in the blood concentration/dose ratio of tacrolimus was associated with change in the hematocrit ratio after transfusion, and more attention is required for children or patients with small body surface area. Dose adjustment of tacrolimus is required if the blood concentration of tacrolimus is much higher than the target concentration.BACKGROUND Although previous studies have suggested that drain management is highly variable, data on drain placement and timing of drain removal among patients undergoing hepatic resection remain scarce. The objective of the current study was to define the utilization of drain placement among patients undergoing major hepatic resection. METHODS The ACS NSQIP-targeted hepatectomy database was used to identify patients who underwent major hepatectomy between 2014 and 2017. Association between day of drain removal, timing of discharge, and drain fluid bilirubin on postoperative day (POD) 3 (DFB-3) was assessed. Propensity score matching (PSM) was used to compare outcomes of patients with a drain removed before and after POD 3. RESULTS Among 5330 patients, most patients had an abdominal drain placed at the time of hepatic resection (n = 3075, 57.7%). Of 2495 patients with data on timing of drain removal, only 380 patients (15.2%) had their drain removed by POD 3. Almost 1 in 6 patients (n = 441, 17.7%) were discharged home with the drain in place. DFB-3 values correlated poorly with POD of drain removal (R2 = 0.0049). After PSM, early drain removal (≤ POD 3) was associated with lower rates of grade B or C bile leakage (2.1% vs. 7.1%, p = 0.008) and prolonged length of hospital stay (6.0% vs. 12.7%, p = 0.009) compared with delayed drain removal (> POD 3). CONCLUSIONS Roughly 3 in 5 patients had a drain placed at the time of major hepatectomy and only 1 in 7 patients had the drain removed early. This study demonstrated the potential benefits of early drain removal in an effort to improve the quality of care following major hepatectomy.PsbV (cytochrome c550) is one of the three extrinsic proteins of photosystem II (PSII) and functions to maintain the stability and activity of the Mn4CaO5 cluster, the catalytic center for water oxidation. PsbV-Y137 is the C-terminal residue of PsbV and is located at the exit of a hydrogen-bond network mediated by the D1-Y161-H190 residue pair. In order to examine the function of PsbV-Y137, four mutants, PsbV-Y137A, PsbV-Y137F, PsbV-Y137G, and PsbV-Y137W, were generated with Thermosynechococcus vulcanus (T. vulcanus). These mutants showed growth rates similar to that of the wild-type strain (WT); however, their oxygen-evolving activities were different. At pH 6.5, the oxygen evolution rates of Y137F and Y137W were almost identical to that of WT, whereas the oxygen evolution rates of the Y137A, Y137G mutants were 64% and 61% of WT, respectively. However, the oxygen evolution in the latter two mutants decreased less at higher pHs, suggesting that higher pHs facilitated oxygen evolution probably by facilitating proton egress in these two mutants. Furthermore, thylakoid membranes isolated from the PsbV-Y137A, PsbV-Y137G mutants exhibited much lower levels of oxygen-evolving activity than that of WT, which was found to be caused by the release of PsbV. In addition, PSII complexes purified from the PsbV-Y137A and PsbV-Y137G mutants lost all of the three extrinsic proteins but instead bind Psb27, an assembly cofactor of PSII. These results demonstrate that the PsbV-Tyr137 residue is required for the stable binding of PsbV to PSII, and the hydrogen-bond network mediated by D1-Y161-H190 is likely to function in proton egress during water oxidation.
