Based on anamnestic and clinical evaluations, blood and serology examinations, the patient resulted with leptospirosis. The bilirubin reached 73.4mg/dL. At the same time on PubMed research we found only limited cases with leptospirosis associated with bilirubinemia over 30mg/dL and over less with hemolytic anemia. Based on our clinical experience, as well as literature data, we suggest that clinicians should have a high index of suspicion in cases of jaundice with exposure possibilities for infectious diseases. Connection of high bilirubinemi over then 30mg/dL and hemolytic anemia in human leptospirosis is an unical case report.

The aim of this study was to investigate the effects of tea on the total antioxidant capacity of saliva among smokers. 24 smokers were selected by convenience sampling. Demographic information and duration of smoking were recorded at the beginning of study. Two cups of tea were given to the participants with specific instruction for 30 days. The unstimulated saliva was collected on first day, 15 and 30 days. Then, total antioxidant capacity was measured by a special kit. Statistical analysis was conducted by repeated measure ANOVA test. The mean values of total antioxidant capacity of saliva were significantly higher in days 15 and 30 from the baseline. (p<0.0001, P=0.006). In day 30, the mean value of antioxidant was not significantly different from day 15. (P=0.271). tea consumption increases salivary antioxidants level in smokers. Melissa officinalis tea consumption increases salivary antioxidants level in smokers. Observing the enhancing plaques in magnetic resonance imaging (MRI) is one of the most valuable diagnostic modalities in confirming the diagnosis of multiple sclerosis (MS), its recurrence and for better detection of active disease. Since active lesions discovery can improve designating diffusion in time diagnosis of MS and controlling disease activity, and there is not any definite time for delay image acquisition, therefore, the aim of the current study was to evaluate the enhancement of MS plaques in different delayed phases. In this interventional study, after receiving written consent, 40 MS patients with at least one enhancing plaque in a previous MRI were evaluated in Babol Ayatollah Rouhani Hospital. Gadolinium was injected to all patients at the dose of 0.1 mg/kg, and MRI was taken at 5 and 15 minutes. The results were analyzed using SPSS 23. A p<0.05 was considered as significant level. The mean of plaque signal intensity was 1190.20 and 1349.60 at 5 and 15 min, respectively, and this difference was significant (p<0.001). Moreover, the mean of plaque total size was 5.16 cm and 7.04 cm at 5 and 15 min with significant difference, respectively (p<0.001). The mean of plaque number was 1.92 and 2.58 at 5 and 15 min, respectively, which was significantly different (P<0.001). The results indicated improvement in detection of MS plaques in images taken in the delayed phase compared to those in the early phase. The plaque intensity, size and number were significantly higher in the delayed phase (15 min), than early phase (5 min).

A routine phenotypic test has not been recommended for the detection of metallo-β-lactamases (MBLs) producing species such as . The current study was conducted to compare the 2-mercaptopropionic acid (2-MPA) phenotypic method and ertapenem non-susceptibility test with polymerase chain reaction in predicting the production of MBLs in clinical isolates of . Antimicrobial susceptibility test for beta-lactam antibiotics were performed by disk diffusion method. All isolates which showed inhibition zones of ≤ 22 mm for CAZ and ≤ 27 mm for CTX were considered potential MBLs producing isolates. The production of MBLs was confirmed using 2-MPA compound. https://www.selleckchem.com/products/pu-h71.html Also, susceptibility to ertapenem was evaluated in all isolates. Conventional PCR was performed to detect IMP-1 and/or NDM-1 genes in all potential MBLs producing isolates. Of 259, 138 (53.3%) isolates were potential MBLs producing bacteria. One hundred and fifteen out of 138 (83.3%) isolates were susceptible to ertapenem. MBLs production was confirmed in 75/138 (54.4%) isolates by 2-MPA phenotypic method. The NDM-1 or/and IMP-1 genes were found in 30/75(40%) and 39/115(33.9%) isolates which were confirmed by 2-MPA and were susceptible to ertapenem, respectively. The sensitivity of 2-MPA method and ertapenem non-susceptibility test compared with PCR were 65.2% and 15.2%, and the specificity was 52.1% versus 82.6%, respectively. This study demonstrated that the 2-MPA phenotypic method does not have acceptable sensitivity and specificity in comparison with PCR, but its results are more reliable for the detection of MBL producing isolates compared with non-susceptibility to ertapenem. This study demonstrated that the 2-MPA phenotypic method does not have acceptable sensitivity and specificity in comparison with PCR, but its results are more reliable for the detection of MBL producing E. coli isolates compared with non-susceptibility to ertapenem. Nowadays, radiotherapy is used effectively for the treatment of head and neck cancers. Mucositis is one of the most important side effects of radiotherapy. Radio-protective agents protect tissues and cells against the adverse effects due to ionizing radiation and cleave radiation-induced free radicals. Lycopene as a potent antioxidant protects cells against oxidative damage by free radical-scavenging. The present study investigated the antioxidant effect of lycopene on oral mucosa of irradiated rats. In this experimental animal study, 28 rats were placed in four groups as follows treated with 50 mg /kg of lycopene (L50), solvent+irradiation (SR), 25 mg / kg of lycopene+irradiation (LR25), and 50 mg / kg of lycopene+irradiation (LR50). The rats received lycopene intraperitoneally. On the irradiation day (day 0) and tenth day of radiation, blood samples were taken from the animals for FRAP and TBARS tests. The results showed that the LR50 group did not show mucositis higher than grade 2. There was a significant difference (p<0.
