Psoralen is the main coumarin component of Fructus psoraleae. Previously, we have found that psoralen induced hepatocytes apoptosis via PERK and ATF6 related ER stress pathways in vitro. In this study, we investigated the toxicity and ER stress induced by psoralen in female C57 mice. Mice were fed with 80 mg/kg of psoralen intra-gastrically for either 3, 7, or 21 days. https://www.selleckchem.com/products/lw-6.html Liver and kidney were weighed and their coefficients were calculated. The serum was isolated to examine the biochemical parameters including alanine aminotransferase (ALT) activity, aspartate aminotransferase (AST) activity, alkaline phosphatase (ALP) activity, blood urea nitrogen (BUN), total bile acid (TBA), total bilirubin (TBIL), and creatinine (CRE). The transcription and expression of ER stress-related markers were determined by Wes-automated Protein Simple system, Western blot and RT-PCR. Psoralen administration for 3 days significantly increased liver coefficients but decreased kidney coefficients of mice. Histopathological examination showed minimal inflammatory cell foci and vacuolar degeneration in the liver. Besides, serum levels of ALT, TBA, BUN, and CRE were markedly altered by psoralen. Moreover, psoralen significantly increased expression and transcription levels of ER stress related markers, including Grp78, PERK, eIF2α, ATF4, IRE1α, ATF6, and XBP1. These results illustrated that psoralen induced liver injuries through ER stress signaling in female mice. Despite the recent advances in surgical techniques and perioperative care, liver resection (especially extended hepatectomy) is still a high-risk procedure with considerable morbidity and mortality. Experimental large animal models are the best option for studies in this regard. The present study was performed to present an easy-to-learn, fast, and multipurpose model of liver resection in a porcine model. Stepwise liver resections (resection of segments II/III, IVa/IVb, and VIII/IV) were performed in eight pigs with intraoperative monitoring of hemodynamic parameters. The technical aspects, tips, and tricks of this method are explained in detail. Based on the specific anatomical characteristics of the porcine liver, all resection types including segmental resection, hemihepatectomy, and extended hepatectomy could be performed in one animal in an easy-to-learn and fast technique. All animals were hemodynamically stable following stepwise liver resection. Stepwise liver resection using stapler in a porcine model is a fast and easy-to-learn method with which junior staff and research fellows can perform liver resection up to extended hepatectomy under stable conditions.

To investigate the effects of video-based information on the anxiety of patients who underwent ultrasound-guided thyroid fine-needle aspiration biopsy. Fifty consecutive patients who underwent thyroid fine needle aspiration biopsy were included in the study prospectively. Patients were divided into two groups before the biopsy. 25 patients in Group 1 received only written information about thyroid biopsy. In Group 2, 25 patients received video-based information along with written information. Baseline anxiety of all the patients was evaluated prior to procedure using STAI-S and STAI-T questionnaires. After the written information was provided to the patients in group 1, the STAI-S questionnaire was repeated. In the same way, group 2 patients were asked to repeat the STAI-S questionnaire after written and video-based information were provided. All patients were asked to evaluate pain during biopsy using visual analog scale (VAS). There was no significant difference between the groups in terms of age and gender. Although the VAS score was lower in group 2, there was no statistically significant difference between the two groups. When the groups were compared in terms of basal anxiety scores, STAI-T was similar in both groups ( = 0.708). Although STAI-S values were similar in pre and post-information patients in Group 1, the STAI-S values in group 2 were statistically significantly decreased. The video based information provided prior to thyroid biopsy draws the attention as an effective and easy to apply method to decrease the anxiety of the patients.

We hypothesized that DOXO-induced cardiotoxicity may be related to the release of inflammatory cytokines in response to the treatment. This study aimed to assess changes in plasma levels of interleukin (IL)-1β, IL-6, IL-10 and tumor necrosis factor (TNF) after chemotherapy and to correlate these levels with cardiac biomarkers and clinical data.Methods Sixty-four patients with breast cancer treated with DOXO were included. Twenty-two subjects (cases) developed cardiotoxicity until one year after the end of DOXO treatment. Cytokines and cardiac markers were evaluated before starting chemotherapy (T0), up to 7 days after the last infusion (T1) and 12 months after the last infusion (T2).Results Higher IL-10 levels were observed in the case group compared to controls at T1 (p = .006) and T2 (p = .046). The IL-1β, IL-6 and TNF levels did not change during treatment in each group (p > .05), nor between the case and control groups. The IL-10 levels were higher at T1 than at T0 and T2 (p less then .05 for both) in the cardiotoxicity group. A correlation between IL-10 and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels at T0 and T2 in the cardiotoxicity group was observed (p = .048 and p = .004, respectively).Conclusion Our study demonstrated that DOXO induced an increase in plasma IL-10 levels in patients who presented cardiotoxicity after treatment, which correlated with NT-proBNP levels.
