Non-significant changes were obtained only after using only medications (P >0.05). The mean values of VAS reduced significantly in the three groups. The least significant differences showed significant changes among the three groups, whereas non-significant differences were obtained between both magnetic and laser groups. Conclusion There were non-significant differences between both magnetic and laser therapy groups. Addition of either magnetic or laser therapy to medications could bring extra positive benefits to patients with DPN. Both magnetic and laser therapy can be applied with medications for the treatment of patients with DPN.

Its effectiveness in pain reduction was compared to low-level laser therapy (LLLT). Methods Sixty-four patients with MTrPs were randomly divided into 2 groups, namely PLLLT and LLLT. Each patient received treatment for a period of 2 weeks, 5 sessions a week. The intensity of laser irradiation to the skin surface was 6 J/cm2 . The system exit power was 160 mw at a 755 nm wavelength. The visual analog scale (VAS) for the 1st, 5th and 10th sessions was analyzed through two-way repeated measures ANOVA. Results Increasing the number of treatment sessions was effective in reducing pain intensity (P>0.05). The effect of LLLT on pain reduction was significantly greater than that of PLLLT (P>0.05). Referred pain (RP), the limitation of neck movement (LNM), the presence of muscular taut band (PMTB) and the sensitivity of muscular taut band (SMTB) were reduced significantly by the end of the 10th session, compared with participants' condition at the beginning of the 1st session in both groups. Conclusion PLLLT and LLLT can effectively treat MTrPs in the trapezius muscles and they reduce RP, LNM, PMTB, and SMTB in particular. However, the effect of the LLLT was significantly greater than that of PLLLT. In accordance with the observed results, LLLT is recommended as an effective method for treating MTrPs.

Nicotine may influence the smooth muscles of the colon and subsequently the gut motility, which leads to a change in the moving rate of digested material through the gastrointestinal tract. Methods Among various techniques, optical detection methods benefit from non-contact and highsensitivity for studying the early effect of nicotine on the cells. Thus, we used an optically ellipsometric method to get the fast and sensitive nicotine effect on the colon cell. Two-dimensional plasmonic platforms by gold deposition onto the polydimethylsiloxane polymer (PDMS) patterned substrate were used as the guest medium of the cell and the sample was excited by all of the visible region wavelengths at different exposure time and maintenance time. Results Our results showed that the phase difference between each polarization increased by augmenting the exposure time of smoke over the cell at a fixed maintenance time and there was a general red-shift by increasing the maintenance time at a fixed exposure time. Conclusion Using different exposure time to cigarette smoke, we optically showed that the cigarette containing the addicting chemical of nicotine had a direct effect on the cultured colon cells on our 2D biocompatible plasmonic chip. It demonstrated considerable changes in the amplitude and phase of the interacted light by injecting nicotine into the system with the aid of the label-free and non-invasive plasmonic technique.

This study aimed to compare the efficacy of clobetasol 0.05% ointment and photodynamic therapy (PDT) using aminolevulinic acid (ALA) and red light in the treatment of severe nail psoriasis. Methods This open-trial study included 69 nails of 8 patients with severe nail psoriasis. Thirty-four nails were treated with clobetasol 0.05% ointment and 35 nails were treated with ALA-PDT. ALAPDT treatment was performed every 3 weeks for 5 cycles; the nails were treated with clobetasol under occlusion every day during the study. All the patients were followed up after 24 weeks. The severity of nail involvement was measured by the Nail Psoriasis Severity Index (NAPSI) scores at the baseline and during the treatment. Results There were no significant differences in the NAPSI scores between the treatment groups in the baseline and weeks 3, 6 and 9 (all P>0.05), although significant differences were found in weeks 12, 15 and 24 (follow-up) (P less then 0.001). A significant time-effect improvement was found in all the nailmatrix, nail-bed and total NAPSI scores in both treatment groups (all P less then 0.001). The patients did not report intense pain and discomfort during irradiation. Conclusion Clobetasol 0.05% ointment seems to be effective in treating nail psoriasis after a treatment period of 15 weeks. However, the efficacy of ALA-PDT at a 24-week follow-up was greater than that of clobetasol.

Background C. difficile is the most common causative agent of hospital-acquired diarrhea. Toxin production in C. difficile appears to be a critical process for induction of the disease. Several factors such as antibiotics can facilitate growth and toxin production in C. difficile. Methods Five C. difficile strains were grown with and without sub-MIC concentrations of metronidazole, ciprofloxacin, and imipenem (0.5x MIC). The bacterial growth was measured by density at OD620 nm in 0, 4, 8, 12 and 24 h post inoculation. Toxin production was detected using ELISA in culture supernatants as well as in cell pellet. Results The five strains showed minor growth variations in the presence and absence of antibiotic sub-MIC values, except for metronidazole, in which the sub-MIC concentration reduced the growth rate of the resistant isolate in comparison with the control without antibiotic. There were no significant variations in the levels of toxin production with the sub-MIC values of antibiotics examined in comparison with antibiotic-free controls. However, the amount of toxin production in the culture supernatant was greater than in the cell pellet. Conclusion The findings of this study suggested that sub-MIC concentrations of antibiotics may have minor effects on bacterial growth and toxin production of C. difficile. Taken together, these findings suggest that presence of antimicrobial agents increased expression levels of certain genes, particularly virulence genes, which may help C. difficile to survive. ©2019 RIGLD.Aim The present study was designed to evaluate the correlation of interleukin 28B (IL28B, IFNL3) rs12979860 mRNA levels, viral load, and liver function among hepatitis C virus (HCV) patients genotype 1a. Lenalidomide order Background HCV is considered essentially hepatotropic and is a major health problem around the world. Methods This study included 100 HCV-infected patients with HCV genotype1a (G1a) and rs12979860 CC genotype. These patients were divided into two groups according to HCV treatment. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and HCV Load were measured and recorded for each patient. IL28B mRNA levels were determined using real-time polymerase chain reaction assay, and their correlation with clinical data were analyzed. STRING was applied to construct a network and identify interactions between IL28B (IFNL3) and its significant neighbor proteins. Results The results revealed a significant relationship between the ALT as well as ALP levels with IL28B rs12979860 mRNA expression level in men, and also with age >50 years. In the treated group, AST level and HCV load had a significant relationship with IL28B mRNA expression level. The results showed that the level of ALP and AST decreased significantly with increased IL28B mRNA expression level in the treated and untreated group, respectively. STRING database showed that IL28B (IFNL3) interacted with ten important neighbor proteins with some of these proteins being involved in signal transduction pathway activating antiviral response. Conclusion This study indicated that rs12979860CC genotype could predict IL28B mRNA expression level in HCV-infected patients with G1a. Furthermore, IL28B mRNA expression level may serve as a useful marker for the development of G1a HCV-associated outcomes. ©2019 RIGLD.Aim To investigate routes of transmission, demographic characteristics, and frequency of different phases of chronic hepatitis B (CHB) in 2000 Iranian patients. Background Knowledge about the most frequent risk factors of CHB and its different phases is very important for optimal prevention and management policy making. Methods In this cross-sectional study, 2000 HBsAg positive patients who were referred to Taleghani Hospital from 2011 through 2018 were enrolled. ELISA method was employed to detect serological markers of CHB. Taking into account the HBV DNA and ALT levels and HBeAg status, the patients were classified in four groups, according to AASLD 2017 guideline. Results Male and female patients had nearly equal frequencies in our study and 82.5 % of them aged more than 20 years. A great number of our patients (95%) were HBeAg negative and the most frequent risk factors of HBV infection were positive periodontal and family history (40.3% and 24.9%, respectively). The majority of our patients were inactive carriers (63.35%), while s mall number of them were in the immune tolerant group (2.15 %). Conclusion Immune tolerance phase group had the minimum number of members in our study and most of them were above 20 years old. This can be due to the mass vaccination of neonates since 1993. Most of CHB patients were in inactive carrier group. Although it is recommended not to treat these patients, performing periodic liver function tests and disease severity assessment is warranted, especially in patients above 40 years old. ©2019 RIGLD.Aim The aim of this study was to compare the different phases of chronic Hepatitis B virus (HBV) infection with different values for normal ALT. Background For many years, the upper limit of 40 IU was considered normal for ALT for both sexes, but in recent years this value is challenged and some guidelines have lowered their limit. Methods In this cross-sectional study, 2000 HBsAg positive patients who were referred to Taleghani Hospital, Tehran, Iran, from 2011 through 2018 were classified in four groups according to American Association of the study of the liver disease (AASLD), European Association of the study of the liver (EASL) /Asian-Pacific Association of the study of the liver (APASL) and American Collage of Gastroenterology (ACG) guidelines. The frequency of each group based on 3 different guidelines was compared. Results In HBeAg positive patients (n=100), the percentage of immune tolerance phase was 43% according to AASLD cutoff for normal ALT (35 IU for men, 25 IU for women), while it was 68% and 28% with regard to EASL/APASL and ACG (30 IU for men, 19 IU for women) cutoffs respectively.
