Transanal Endoscopic Operation for Benign Rectal Lesions and T1 Carcinoma

Transanal endoscopic operation (TEO) is a minimally invasive technique used for local excision of benign and selected malignant rectal lesions. The purpose of this study was to investigate the feasibility, safety, and oncological outcomes of the procedure and to report the experience in 3 centers.status: publishe

Totally extraperitoneal laparoscopic inguinal hernia repair using a self-expanding nitinol framed hernia repair device: A prospective case series

The use of a self-expanding nitinol framed prosthesis (ReboundHRD(®)) for totally extraperitoneal laparoscopic inguinal hernia repair (TEP-IHR) could solve issues of mesh shrinkage and associated pain. We prospectively evaluated the use of the ReboundHRD(®) mesh for TEP-IHR.publisher: Elsevier articletitle: Totally extraperitoneal laparoscopic inguinal hernia repair using a self-expanding nitinol framed hernia repair device: A prospective case series journaltitle: International Journal of Surgery articlelink: http://dx.doi.org/10.1016/j.ijsu.2017.02.091 content_type: article copyright: © 2017 IJS Publishing Group Ltd.

In Vitro Antibacterial Activities of DQ-113, a Potent Quinolone, against Clinical Isolates

The antibacterial activity of DQ-113, formerly D61-1113, was compared with those of antibacterial agents currently available. MICs at which 90% of the isolates tested are inhibited (MIC(90)s) of DQ-113 against clinical isolates of methicillin-susceptible and -resistant Staphylococcus aureus and methicillin-susceptible and -resistant coagulase-negative staphylococci were 0.03, 0.008, 0.03, and 0.06 μg/ml, respectively. Moreover, DQ-113 showed the most potent activity against ofloxacin-resistant and methicillin-resistant S. aureus, with a MIC(90) of 0.25μg/ml. DQ-113 inhibited the growth of all strains of Streptococcus pneumoniae, including penicillin-resistant strains, and Streptococcus pyogenes at 0.06 μg/ml, and DQ-113 was more active than the other quinolones tested against Enterococcus faecalis and Enterococcus faecium with MIC90s of 0.25 and 2 μg/ml, respectively. Against vancomycin-resistant enterococci, DQ-113 showed the highest activity among the reference compounds, with a MIC range from 0.25 to 2 μg/ml. DQ-113 also showed a potent activity against Haemophilus influenzae, including ampicillin-resistant strains (MIC90, 0.015 μg/ml), and Moraxella catarrhalis (MIC90, 0.03 μg/ml). The activity of DQ-113 was roughly comparable to that of levofloxacin against all species of Enterobacteriaceae. The MICs of DQ-113 against ofloxacin-susceptible Pseudomonas aeruginosa ranged from 0.25 to 2 μg/ml, which were four times higher than those of ciprofloxacin. From these results, DQ-113 showed the most potent activity against gram-positive pathogens among antibacterial agents tested

Laparoscopic parenchymal preserving hepatic resections in semiprone position for tumors located in the posterosuperior segments

All patients who underwent laparoscopic liver resections in the posterosuperior segments (LPSS) at our center were positioned in semiprone since August 2011. The aims of this study were to assess differences in perioperative outcomes between laparoscopic left lateral sectionectomies (LLLS) performed in supine position and LPSS in semiprone position.status: publishe

Antitumor Effects of Orally Administered Rare Sugar D-Allose in Bladder Cancer

D-allose is a rare sugar that has been reported to up-regulate thioredoxin-interacting protein (TXNIP) expression and affect the production of intracellular reactive oxygen species (ROS). However, the antitumor effect of D-allose is unknown. This study aimed to determine whether orally administered D-allose could be a candidate drug against bladder cancer (BC). To this end, BC cell lines were treated with varying concentrations of D-allose (10, 25, and 50 mM). Cell viability and intracellular ROS levels were assessed using cell viability assay and flow cytometry. TXNIP expression was evaluated using Western blotting. The antitumor effect of orally administered D-allose was assessed using a xenograft mouse model. D-allose reduced cell viability and induced intracellular ROS production in BC cells. Moreover, D-allose stimulated TXNIP expression in a dose-dependent manner. Co-treatment of D-allose and the antioxidant L-glutathione canceled the D-allose-induced reduction in cell viability and intracellular ROS elevation. Furthermore, oral administration of D-allose inhibited tumor growth without adverse effects (p < 0.05). Histopathological findings in tumor tissues showed that D-allose decreased the nuclear fission rate from 4.1 to 1.1% (p = 0.004). Oral administration of D-allose suppressed BC growth in a preclinical mouse model, possibly through up-regulation of TXNIP expression followed by an increase in intracellular ROS. Therefore, D-allose is a potential therapeutic compound for the treatment of BC
