and photophysical investigations

A highly selective and sensitive fluorescent sensor for mercury ion has been obtained from a combination of Bodipy and Calix[4]arene derived by click chemistry. The structural characterization of all compounds had been carried out by FT-IR, H-1 NMR, C-13 NMR, MS, elemental analysis or melting point. Calix[4]-B including a calix[4]arene and two Bodipy units is a good fluorescent sensor for Hg(II). It can be explained by the coordination between mercury and the triazole rings. In a co-solvent of methanol and water, the complexation ratio for Calix[4]-B/Hg(II) was determined as 1:1 and the binding constant was found to be 3.42 x 10 (7) M-1. The detection of Hg(II) by Calix[4]-B works selectively in aqueous methanol mixture. (C) 2017 Elsevier B.V. All rights reserved

Coincidental detection of T-cell rich B-cell lymphoma in the paraaortic lymph nodes of a woman undergoing lymph node dissection for cervical cancer

The diagnosis of cervical squamous cell carcinoma with concurrent T-cell rich B-cell lymphoma in dissected lymph nodes has not been reported to our knowledge. We report such a case. The biopsy of an exophytic lesion at the uterine cervix showed squamous cell carcinoma in a 50-year-old woman presenting with postcoital bleeding. Type III hysterectomy, bilateral salpingo-oophorectemy, bilateral pelvic, paraaortic lymph node dissections were performed. Pathologic examination revealed a T-cell rich B-cell lymphoma in some lymph nodes beside squamous cell carcinoma in several of others. ELISA for human immuno-deficiency virus (HIV) was negative. The cervical carcinoma was staged as FIGO clinical stage IB1 and the lymphoma as Ann Arbor IIA. Six cycles of CHOP (cyclophosphamide, adriamycin, vincristine, and prednisone) chemotherapy for the lymphoma and concomitant pelvic chemo-radiotherapy with cisplatin for cervical cancer were given. In this rare coincidence; the best available therapy for each of the diseases should be considered individually. We also suggest that HIV screening test be carried out, because both diseases may be related to human immuno-deficiency virus, although our patient was HIV-negative

Group I in which ISB was performed and patient-controlled analgesia (PCA) was inserted, Group II with; ISB and SSNB combined, and PCA was inserted, and Group III where; only PCA was used. Visual analog scale (VAS) pain scores at the second, fourth, sixth, 12th, and 24th hours, morphine consumption, additional analgesic requirement, and patient satisfaction were evaluated.Results: Compared with Group III, the VAS pain score was significantly lower in Group I and Group II at 2, 4, 6, 12, and 24 hours postoperatively. In Group I, the VAS score at rest at the 6th hour was found to be higher than in Group II. The 24-hour total morphine consumption was higher in the control group than in Group I and Group II. The satisfaction score of the control group was lower than Group I and Group II.Conclusion: The combined application of ISB and SSNB block is beneficial in shoulder surgery to provide both intraoperative and postoperative analgesia and opioid consumption.Level of Evidence: Level I; Randomized Controlled Trial; Treatment Study.Keywords: interscalene block, suprascapular nerve block, shoulder arthroscopic surgery, postoperative analgesi

Effect of diets containing sesame oil on growth and fatty acid composition of rainbow trout ( Oncorhynchus mykiss

The aim of this study was to investigate effects of fish oil replacement by sesame oil in combination with other vegetable oils in diets with regard to growth performance, feed utilization, desaturation and elongation, whole fish and liver fatty acid profiles of juvenile rainbow trout. Sesame oil (SO) used in the feeds was a mixture of linseed (LO), sunflower (SFO) and fish oil (FO), whereas the control diet contained only FO. Duplicate groups of 60 rainbow trout (similar to 7g) held under similar culture conditions were fed 2% of their body weight per day for 75days. At the end of feeding trials, there was no difference in feed utilization efficiency or growth performance between the control group and the groups with added sesame oil (P>0.05). However, viscerosomatic and hepatosomatic index values were significantly higher (P0.05). Diets with sesame oil increased desaturation and elongation of 18:3n-3 towards n-3 HUFA. The conclusion was that the diet addition of sesame oil in combination with other vegetable oils increased the nutritional quality of the whole fish and liver of juvenile rainbow trout, in particular the docosahexaenoic acid (DHA) level. Therefore, sesame oil may be of interest for use in aquaculture

Physicochemical characterization and antioxidant activity of 17 commercial Moroccan honeys

In this study, 17 commercial honey samples from Morocco were analyzed. Four samples did not meet the international physicochemical standards due to high hydroxymethylfurfural content and low diastase activity. Phenol content varied from 163.82mg gallic acid equivalent (GAE)/kg in citrus honey to 923.70mg (GAE)/kg in thyme honey from Rachidia; flavonoid content ranged from 4.26mg quercetin equivalent (QE)/kg in citrus honey to 139.62mg QE/kg in black cumin honey. Black cumin honey had the highest peroxyl scavenging activity; oregano (from Zaraphyt) and thyme honeys (from Rachidia) had the highest ABTS (2,2'-azino-bis[ 3-ethylbenzothiazoline-6-sulphonic acid]) scavenging activity; and thyme honey (Saouira) had the highest NO scavenging capacity. The antioxidant activity of Moroccan honeys was correlated with the phenol, flavonoid, and melanoidin contents. Dark honeys had higher antioxidant activity than light honeys. Samples with high sodium levels had lower free radical scavenging activity. On the other hand, calcium and magnesium increased the ABTS and peroxyl scavenging capacity, respectively, of honey samples. According to cluster and discriminant analyses, the honey samples were grouped in three clusters with respect to the phenol, flavonoid, melanoidin, proline, mineral and sugar contents, and free radical scavenging capacity
