Abstract. Background: We investigated the association of the 5A/6A polymorphism in the promoter region at -1612 of the matrix metalloproteinase-3 gene (MMP-3-1612) and deep venous thrombosis (DVT). Patients, materials and methods: The distribution of the MMP-3 (-1612 5A/6A) polymorphism in the case and control groups was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Serum MMP-3 level of two groups was detected using enzyme-linked immunosorbent assay (ELISA). HepG2 cells containing MMP-3-1612 recombinant plasmid were cultured in vitro and the MMP-3 level was defined by luminescence intensity of luciferase. A DVT rat model was built. Serum MMP-3 level in the rats’ wounded vein at different time points was detected by ELISA and recorded for investigation of the association between MMP-3 and DVT. Statistical data analysis was conducted with SPSS18.0. Results: On the basis of the observation of MMP-3-1612 genotype frequency and allele frequency in the case and control groups, we identified significantly higher MMP-3-1612 5A allele frequency and higher serum MMP-3 level in the case group than in the control group (both P < 0.05). According to in vitro luciferase measurements, the 5A allele had higher transcriptional activity than the 6A allele. As observed in the rat model, serum MMP-3 level increased with time passing and thrombosis formation after modelling. Conclusions: The MMP-3-1612 5A/6A polymorphism may effect serum MMP-3 level and over-expression of serum MMP-3 level may be a risk factor for DVT formation.

Prothrombin Gene

SummaryA dimorphism in the 3’-untranslated region of the prothrombin gene (G to A transition at position 20210) has recently been reported to be associated with increases in plasma prothrombin levels and in the risk of venous thrombosis (1). We have examined the prothrombin dimorphism among 99 unselected outpatients with phlebography verified deep venous thrombosis, and in 282 healthy controls. The prevalence of the 20210 A allele was 7.1% (7/99) in the patient group, and 1.8% (5/282) in the healthy control group (p = 0.0095). The relative risk of venous thrombosis was calculated to be 4.2 (95% Cl, 1.3 to 13.6), and was still significant when adjustment was made for age, sex and the factor V:R506Q mutation causing APC resistance [odds ratio 3.8 (95% Cl, 1.1 13.2)]. As previously reported, 28% of the patients were carriers of the factor V:R506Q mutation. Thus, 34% (one patient carried both traits) of unselected patients with deep venous thrombosis were carriers of an inherited prothrombotic disorder. To sum up, our results confirm the 20210 A allele of the prothrombin gene to be an important risk factor for venous thrombosis.

Objective: To evaluate the association between the Factor V Leiden (FV R506Q) and prothrombin gene (FII G20210A) mutations and deep venous thrombosis (DVT) in young people. Methods: Blood samples were drawn from 199 subjects: 100 healthy controls and 99 unselected patients, with an objectively documented first episode of DVT under 40 years old. DNA analysis was performed using the polymerase chain reaction. Results: The mean age in the patient cohort was 27 years (range 16–40) and 68 (68.7%) were women. Patient prevalences were 20.6% and 10.1% for FV R506Q and FII G20210A, respectively. In the control group, carrier frequencies were 2% and 5%, respectively. We found an increased overall relative risk of DVT with statistical significance for FV R506Q carriers (OR: 12.8; 95% CI: 2.9–56.7; P < 0.001), but not for FII G20210A mutation (OR: 2.1; 95% CI: 0.7–6.5; P = 0.19). Conclusions: Our results suggest a possible increase in DVT risk for the young G20210A allele carriers, which can be more expressed in the presence of a circumstantial risk factor. There is extremely strong evidence that the Factor V Leiden mutation is an important risk factor in the development of a first episode of DVT in young people.

Shade Selection

This study aimed to investigate and compare the reliability and accuracy of tooth shade selection in the model using 30 milled crowns via five methods: (1) digital single-lens reflex (DSLR) camera with twin flash (TF) and polarized filter (DSLR + TF), (2) DSLR camera with a ring flash (RF) and polarized filter (DSLR + RF), (3) smartphone camera with light corrector and polarized filter (SMART), (4) intraoral scanner (IOS), and (5) spectrophotometer (SPEC). These methods were compared with the control group or manufacturer’s shade. The CIE Lab values (L, a, and b values) were obtained from five of the methods to indicate the color of the tooth. Adobe Photoshop was used to generate CIE Lab values from the digital photographs. The reliability was calculated from the intraclass correlation based on two repetitions. The accuracy was calculated from; (a) ΔE calculated by the formula comparing each method to the control group, (b) study and control groups were analyzed by using the Kruskal–Wallis test, and (c) the relationship between study and control groups were calculated using Spearman’s correlation. The reliability of the intraclass correlation of L, a, and b values obtained from the five methods showed satisfactory correlations ranging from 0.732–0.996, 0.887–0.994, and 0.884–0.999, respectively. The ΔE from all groups had statistically significant differences when compared to the border of clinical acceptance (ΔE = 6.8). The ΔE from DSLR + TF, DSLR + RF, SMART, and SPEC were higher than clinical acceptance (ΔE > 6.8), whereas the ΔE from IOS was 5.96 and all of the L, a, and b values were not statistically significantly different from the manufacturer’s shade (p < 0.01). The ΔE of the DSLR + RF group showed the least accuracy (ΔE = 19.98), whereas the ∆E of DSLR + TF, SMART, and SPEC showed similar accuracy ∆E (ΔE = 10.90, 10.57, and 11.57, respectively). The DSLR camera combined with a ring flash system and polarized filter provided the least accuracy. The intraoral scanner provided the highest accuracy. However, tooth shade selection deserves the combination of various techniques and a professional learning curve to establish the most accurate outcome.

SummaryRabbits play an important role in people’s lives due to their high nutritional value and high-quality hair that can be used as raw material for textiles. Furthermore, rabbits are an important animal model for human disease, as genome-edited animals are particularly valuable for studying gene functions and pathogenesis. Somatic cell nuclear transfer (SCNT) is an important technique for producing genome-edited animals and it has great value in saving endangered species and in clone stem cell therapy. However, the low efficiency of SCNT limits its application, with the selection of suitable rabbit oocytes being crucial to its success. In the present study, we collected oocytes from ovarian follicles and stained them with 26 μM brilliant cresyl blue (BCB). We then matured the oocytes in vitro and used them for SCNT. Comparison of the BCB-positive oocytes with BCB-negative oocytes and the control group showed that the BCB-positive group had a significantly higher maturation rate (81.4% vs. 48.9% and 65.3% for the negative and control groups, respectively), cleavage rate (86.6% vs. 67.9% and 77.9%), blastocyst rate (30.5% vs. 12.8% and 19.6%), total number of blastocysts (90±7.5 vs. 65.3±6.3 and 67.5±5.7), and inner cell mass (ICM)/ trophectoderm (TE) index (42.3±4.2 vs. 30.2±2.1 and 33.9±5.1) (P<0.05). The BCB-positive group had a significantly lower apoptosis index (2.1±0.6 vs. 8.2±0.9 and 6.7±1.1 for the negative and control groups, respectively) (P<0.05). These findings demonstrate that BCB-positive oocytes have a higher maturation ability and developmental competence in vitro, indicating that BCB staining is a reliable method for selecting oocytes to enhance the efficiency of SCNT.

AbstractBackground and objectives:Chronic nonspecific pharyngitis is a chronic inflammation of the pharynx. It is found worldwide, and treatment is difficult. The underlying aetiopathogenesis is still controversial. The aim of this study was to investigate Helicobacter pylori seroprevalence in chronic nonspecific pharyngitis patients without other possible causative factors for chronic pharyngeal irritation and without H pylori gastric mucosal infection.Materials and methods:Forty-one patients with symptoms of chronic nonspecific pharyngitis and 30 healthy control subjects were enrolled in this prospective, controlled, clinical study. In both study and control groups, selected patients were shown to have gastric mucosa uninfected by H pylori, as demonstrated by the 14C-urea breath test. Comprehensive otorhinolaryngological examination did not elicit any factor contributing to the chronic pharyngeal complaint. Serum H pylori immunoglobulin G antibody titres were assayed using serum enzyme-linked immunosorbent assay. The difference between the study and control groups was analysed by the chi-square test (the likelihood ratio was used).Results:Thirty-two of the 41 patients (78 per cent) and 14 of the 30 control subjects (46.7 per cent) were found to be H pylori positive. Patients with chronic nonspecific pharyngitis were found to have a significantly higher rate of H pylori seropositivity than the control group (p = 0.016).Conclusion:These data may be important in developing future treatment strategies for chronic nonspecific pharyngitis.

SummaryThe present study investigated the effects of crotamine, a cell-penetrating peptide from rattlesnake venom, at different exposure times and concentrations, on both developmental competence and gene expression (ATP1A1, AQP3, GLUT1 and GLUT3) of in vitro fertilized (IVF) bovine embryos. In Experiment 1, presumptive zygotes were exposed to 0.1 μM crotamine for 6, 12 or 24 h and control groups (vehicle and IVF) were included. In Experiment 2, presumptive zygotes were exposed to 0 (vehicle), 0.1, 1 and 10 μM crotamine for 24 h. Additionally, to visualize crotamine uptake, embryos were exposed to rhodamine B-labelled crotamine and subjected to confocal microscopy. In Experiment 1, no difference (P > 0.05) was observed among different exposure times and control groups for cleavage and blastocyst rates and total cells number per blastocyst. Within each exposure time, mRNA levels were similar (P > 0.05) in embryos cultured with or without crotamine. In Experiment 2, concentrations as high as 10 μM crotamine did not affect (P > 0.05) the blastocyst rate. Crotamine at 0.1 and 10 μM did not alter mRNA levels when compared with the control (P > 0.05). Remarkably, only 1 μM crotamine decreased both ATP1A1 and AQP3 expression levels relative to the control group (P < 0.05). Also, it was possible to visualize the intracellular localization of crotamine. These results indicate that crotamine can translocate intact IVF bovine embryos and its application in the culture medium is possible at concentrations from 0.1–10 μM for 6–24 h.

Objective: The objective of this research was to evaluate the effect of different concentrations of Aloe vera (AV) on inflammation of diabetic ulcers in a rat model.Methods: The induction of diabetes was conducted by injection of alloxan monohydrate. This study involved four groups, including 0%, 10%, 30%, and inner leaf AV (ILAV) gel groups. Necrotic tissue, wound size, inflammation, and reepithelialization were evaluated. Wound tissue was collected on days 4 and 8. Histological analysis was performed by hematoxylin and eosin staining. Differences in the intensity of inflammation were analyzed using Kruskal–Wallis test followed by Mann–Whitney U-test.Results: On day 13, wounds in gels containing AV were almost completely healed, whereas wounds in the 0% gel group (control) were still covered with necrotic tissue. On day 3, the intensity of inflammation in the 30% and ILAV groups was significantly less when compared to the 10% and control groups. On day 8, inflammation was less significant in the 10%, 30%, and ILAV groups when compared with the control group. Moreover, the intensity of inflammation in the 30% and ILAV groups was significantly less compared to the 10% group. In addition, reepithelialization was more advanced in the 10% and 30% ILAV groups compared with the control group, and reepithelialization was most advanced in the 30% and ILAV groups.Conclusion: Our study indicated that gels containing AV reduced inflammation and improved reepithelialization of diabetic ulcers in a rat model. Therefore, it is highly recommended for clinicians to use AV gels for topical treatment of diabetic ulcers.

Abstract Background T- shaped uterus may be associated with infertility and adverse pregnancy outcomes. Hysteroscopic metroplasty may improve the reproductivity for these cases. To our knowledge, there is no data in literature about the clinical consequences of in vitro fertilization (IVF) in patients undergoing hysteroscopic metroplasty for T-shaped uterus. The principal objective of the current study is to assess the impact of hysteroscopic metroplasty for T-shaped uterus on the reproductive outcomes of IVF. Methods IVF outcomes of 74 patients who underwent hysteroscopic metroplasty for T- shaped uterus and 148 patients without any uterine abnormalities and with diagnosis of unexplained infertility (control group) were retrospectively analyzed. Results Patients in metroplasty and control groups were comparable with respect to age, BMI, partner’s age and duration of infertility. Number of patients with a history of pregnancy beyond 20 weeks of gestation was significantly lower in the metroplasty group (4.1% vs 18.2%; p < 0.05). Number of previous unsuccessful cycles and percentage of patients with ≥3 unsuccessful IVF cycles (35.1% vs 17.6%; p < 0.05) were significantly higher in the metroplasty group. There were no significant differences in the reproductive outcomes such as the pregnancy rate, clinical pregnancy or live birth rate between the metroplasty and control groups. There were non-significant trends for higher rates of miscarriage (18.8% vs 8%, p > 0.05) and biochemical pregnancy (20.0% vs 10.7%, p > 0.05) in the metroplasty group compared to the control group. Conclusions Reproductive results of the IVF cycles after hysteroscopic correction of T-shaped uterus were comparable to those of the patients without any uterine abnormalities and with diagnosis of unexplained infertility. Hysteroscopic metroplasty may contribute to improved IVF outcomes in patients with T-shaped uterus.

OBJECTIVE: This study aimed to compare cycle outcomes among women with endometrioma or non-functional cysts versus control. STUDY DESIGN: Women under 35 years of age with unexplained infertility underwent in vitro fertilization cycle. Two hundred and ninety-nine women were included in this study. Study groups consist of women with endometrioma (n=82) or non-functional ovarian cysts (n=100) and control group (n=117). Women in each group were selected consecutively. Groups were matched for age and ovarian reserve and compared in terms of in vitro fertilization cycle outcome. RESULTS: There were no significant differences among groups in terms of mean age, early follicular phase Follicle-Stimulating Hormone, and anti-müllerian hormone levels (p>0.05). Baseline total antral follicle counts were similar among groups (p>0.05). There were significant differences among groups in terms of mean starting and total gonadotropin dose, peak estradiol level, total oocyte number, and mature oocyte numbers (p<0.05). Clinical pregnancy rates were 10.7%, 17.3%, and 31.6% in groups with non-functional cyst, endometrioma and control group respectively (p<0.05). The presence of a non-functional cystic mass of ovary on the starting day of stimulation was a risk factor for poor cycle outcome in terms of clinical pregnancy rates [OR=0.5 (95 % CI; 0.2-0.9, p=0.03)]. CONCLUSION: Our data showed that the presence of any kind of cystic mass of the ovary especially the non-functional cysts on the starting day of stimulation was a risk factor for poor cycle outcomes in terms of clinical pregnancy rates.

In order to reduce fetal losses of bovine clones the replacement of trophectoderm (TE) by microinjection of immunosurgically isolated inner cell mass (ICM) was proposed. It was reported that those techniques could damage both ICM and TE. An alternative to decrease this problem would be the technique of cell aggregation by approximation. Currently it has been used only in pre-compaction embryos. The aims of this study were to evaluate the effectiveness to aggregate post-compaction embryos and to verify the feasibility of reconstructed blastocysts production by ICM and TE approximation. Mice (Swiss Webster, SW; and C57BL/6/EGFP, EGFP) were superovulated to obtain embryos 2.5 to 3.5 days post-coitus. In both control groups (CG; exp. 1 and 2), whole embryos from 8 cells to early morula stages and without zona pellucida were aggregated. In all experiments, bisection was performed with a blade controlled by micromanipulator to produce two fragments according to the requirements of each experiment (i.e. demi embryos in Exp. 1 and Exp. 2 or TE fragment and whole ICM in Exp. 3). The joined fragments were in vitro cultured in microwell (300 µm diameter and based on well of the well system) filled with 400 µL of KSOMaa, covered with mineral oil by 24 h (incubation 37°C, 5% of CO2 and saturated humidity). Embryonic aggregation rate (AR) was evaluated by detection of a single and cohesive cell mass (CG from Exp. 1 and Exp. 2) or by the presence of a typical morphologically blastocyst (all the remaining groups). Only to validate AR evaluation, 25% of the aggregation attempts were performed with distinct phenotype embryos (EGFP and SW) and they could be tracked under epifluorescence. In Exp. 1, the aggregation by approximation was tested to evaluate embryonic stages: 2 demi-blastocysts (2DB; n = 28), demi-morula and demi-blastocyst (DMDB; n = 20) and control group (CG; n = 25). In Exp. 2, an adhesive agent (phytohemagglutinin; PHA) and fragment increasing were used in the groups: 2DB (n = 24), 4 demi-blastocysts (4DB, that is four half-blastocyst) and CG (n = 22). After aggregation validation (Exp. 1 and Exp. 2), blastocyst reconstruction by the approximation of ICM and TE fragments (with PHA presence) was tested on groups: 1 TE fragment and 1 ICM (TI; n = 48) and 2 TE fragments and 1 ICM (2T1I; n = 17). The rates were analyzed by chi-square and Fisher’s exact tests (significance of 5%). In experiments 1 (3.6; 15.0; and 60.0%, respectively to 2DB, DMDB, and CG) and 2 (8.3; 36.4; and 77.3%, respectively to 2DB, 4DB, and CG), the AR differed among groups with exception of 2DB and DMDB (exp. 1; P > 0.05). In Exp. 3, there was no difference on the AR between TI and 2T1I (27.1 and 29.4%, respectively). Despite the low adhesion potential of the trophectoderm cells, is feasible to produce chimeric embryos by aggregation. We infer that the use of an adhesive agent could increase AR maintaining the contact of the embryonic fragments. The proposed technique was practical and effective for blastocyst reconstruction. Additionally, the present model established in mice is about to be tested in cattle for further validation. Financial support: FAPESP.
