Objective: To determine the predictors of absence of lesion on cone biopsy (white cone). We evaluated several factors including parity, cytology, human papillomavirus (HPV) typing, biopsy, colposcopy, smoking habit, use of oral contraceptive or condom, and immunosuppression as predictors for absence of dysplasia. Methods: Of 510 patients with CIN (cervical intraepithelial neoplasia) treated by loop electrosurgical excision (LEEP) in the Fundación Jimenez Diaz hospital between 2012 and 2016, 51 (10%) patients had a white cone and were defined as the study group. The control group was established from two randomly selected controls for each case (n = 102). Results: The study group had a higher prevalence of low-grade cytology (p 0.001), minor changes (p 0.01), and CIN 2 (<0.001) than the control group. The study group had a lower rate of oral contraceptive use (p = 0.005), as demonstrated by the multivariate analysis (except for low-grade cytology). Conclusions: In conclusion, this study indicates that the incidence of white cone in our institution is 10% of all the cone biopsy and women with low-risk cytology, minor changes in colposcopy, CIN 2, and no use of oral contraceptive have a high probability of having no lesions in the conization specimen.

Seedlessness is a desirable characteristic in citrus fruits sold for fresh consumption. Gamma irradiation is widely used to obtain seedless citrus fruits. Here, different clones of the self-incompatible parthenocarpic ‘Moncada’ mandarin, obtained by gamma irradiation, were studied to assess seedlessness, pollen germination, fruit characteristics and qua- lity attributes. Findings indicate that irradiation altered aspects other than seedlessness, such as pollen germination, and some of the clones presented different weight, size, acidity and maturity index. Fruit quality and nutritional bio- components were affected differently;some clones presented no changes compared to the control ‘Moncada’ man-darin, while other clones showed significant differences. In general, all clones examined presented low seed numbers and re- duced pollen viability. Some of these clones, which ripen late in the season and whose fruit quality is maintained or improved, are in the process of registration.

Deep shear-wave velocity profiles at eight places in Lima Peru were estimated based on the inversion of dispersion curves. The dispersion curves were calculated from small and large microtremor arrays using two methods： the F-k proposed by Capon （1969） and the CCA proposed by Cho et al. （2004）. For the purpose of large array measurement we introduced a new type of sensor. Important results are the relative shallow depths to the basement rock in the area classified as alluvial gravel that covers most of the area of Lima city; and the relative large depth to the bedrock in places identified as VSV and CMA. It is recommended that this study be complemented with PS loggings in order to verify the estimated profiles.

AIM： To assess whether CCL2 or interactions between this chemokine and its receptor （CCR2） are associated with outcomes of chronic hepatitis C and with responses to antiviral therapy. METHODS： Two hundred and eighty-four patients with chronic hepatitis C and 193 non-infected matched controls were included in this study. Patients were categorized according to their Scheuer score of hepatic fibrosis as F0-F2 （/7 = 202） or F3-F4 （/7 = 82） and according to their response to anti-Hepatitis C virus （HCV） therapy as sustained response （SR, n = 201） or non-sustained response （NSR, n = 98）. Genotyping of the -2518 （A/G） CCL2 was performed using PCR-RFLP, genotyping of the 190 （A/G） CCR2 using a PCR-ARMS system, and genotyping of the rs3138042 （G/A） CCR2 using Taqman probes. RESULTS： Univariate analyses identified 4 parameters （infection duration time, viral genotype, gender and AST levels） that tended to influence fibrosis and 7 parameters （CCL2G, CCL2ACCR2A, viremia levels, fibrosis stage, viral genotype, infection duration time and AST levels） that significantly influenced or tended to influence response to treatment. Multivariate analysis identified gender and AST levels as parameters that independently influenced fibrosis stage and viral genotype and infection duration time were the two parameters that independently influenced response to treatment. CONCLUSION： Our results indicate that the mutations studied in the gene pair CCL2/CCR2 do not play a major role in the outcome and response to treatment for HCV infection in the Spanish population.
