Background: Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality. There is a need for a marker associated with HCC progression. A disintegrin and metalloprotease (ADAMs) family proteins have a lot of functions in cell adhesion, migration, proteolysis and signaling. Aim: The aim of the study was to investigate the relation between ADAM 10 gene single nucleotide polymorphisms (SNPs) and HCC progression. Methods: This study involved 201 cases divided: Group I (67 HCC patients), Group II (67 cirrhotic patients), Group III (67 control). Each group was subjected to laboratory investigations: (CBC, blood sugar, kidney and liver function, viral markers, alpha fetoprotein), imaging: (abdominal ultrasonography, and triphasic C.T) and ADAM 10 gene polymorphism (rs 653765, rs 383902) detection by real – time PCR. Results: There was a statistically significant difference in the frequency and genotyping of ADAM10 SNPs in HCC patients in comparison to cirrhotic and control groups [the frequency of rs 653765 genotypes (p=0.015) and model (p=0.013)]; likewise, the frequency of rs 383902 genotypes (p<0.001) and model (p=0.001)). Also, there was a statistically significant association between different SNP rs 383902 genotype with CLIP stages (p=0.02), and with VISUM stages (p=0.035). Conclusion: ADAM-10 are overexpressed in HCC patients and involved in HCC progress. These findings highlight that ADAM inhibitor may be used as therapeutic goals in treatment of HCC.

Abstract Background Hepatocellular carcinoma and hepatitis C are strongly associated. The current work aimed to study the expression levels of microRNA-331-3p and microRNA-23b-3p as propable biomarkers for detecting liver cancer (HCC) at its early stages in patients with HCV-related liver cirrhosis. The current prospective study included two hundred participants, divided into three groups: group I, 100 patients with HCV-related liver cirrhosis; group II, 50 HCC patients at early stages; and group III, 50 apparentlyhealthy controls. All patients had routine laboratory workup and ultrasound hepatic assessment. Values of microRNA-331-3p and microRNA-23b-3p were measured by real-time quantitative PCR. Results Levels of miR-331-3p were significantly higher in HCC patients than in cirrhotic patients and controls (p < 0.001), while levels of miR-23b-3p were significantly lower in HCC patients compared to cirrhotics and controls (p < 0.001). ROC curve revealed that miR-23b-3p had 80% sensitivity and 74% specificity, miR-331-3p had 66% sensitivity and 61% specificity, and AFP had 64% sensitivity and 61% specificity of 61% in discrimination between HCC patients from controls. Conclusion Serum miR-23b-3p is a more effective predictor than miR-331-3p and AFP for the development of hepatocellular carcinoma in hepatitis C (HCV)-related cirrhotic patients.

Background and Aims: Programmed cell death-1 (PD-1) has a vital role in regulating T-cell function, and immune escape mechanism of cancer cells. It was shown that there could be a relationship between single nucleotide polymorphisms (SNPs) in the PD-1 gene and susceptibility to hepatocellular carcinoma (HCC) based on various studies. We aimed to investigate the role of three SNPs within the PD-1 gene in susceptibility to HCC in the Turkish population. Methods: Single nucleotide polymorphisms of PD-1.1, 1.5, and 1.6 were genotyped by using TaqMan Allelic Discrimination Assays in blood samples of 137 HCC and 136 control subjects, matched for age and gender. The genotype, allele and haplotype frequencies were compared in HCC and control groups using logistic regression analysis. Results: Genotype distributions of PD-1.1, PD-1.5 and PD-1.6 SNPs were in Hardy-Weinberg equilibrium. No significant difference was observed in the genotype distribution of PD-1.1, PD-1.5 and PD-1.6 polymorphisms among gender and age-matched HCC (M/F: 96/41; mean age: 61.4 ±11.7 years) and control group (M/F: 94/42; mean age: 61.4±10.1). In the haplotype analysis of PD-1.1/PD-1.5/PD-1.6, no significant difference was found among HCC and control group adjusted for sex and age (all p values>0.1). Conclusion: Our findings, firstly reporting the association of PD-1.5 polymorphism with HCC, and PD-1.1 and PD-1.6 with HCC in the Turkish population, suggest that PD-1 polymorphisms are not predisposing factors for HCC development. Future studies with larger sample sizes and different ethnic populations are required to validate our findings.

A study was conducted in 18 healthy, fertile, non-pregnant, dioestrous female dogs to evaluate the efficacy of PGF2? analogue (cloprostenol sodium) in shortening the dioestrus. Bitches that were diagnosed non-pregnant by trans-abdominal ultrasonography, on day 30 of breeding and their dioestrual stage confirmed by serum progesterone assay, were randomly allotted to three groups of six bitches each. Group I and II bitches were treated with cloprostenol sodium @ 2.5 µg/kg b. wt., subcutaneously, thrice at 48 h interval, beginning on day 30 and 45 of last breeding, respectively. Group III animals were assigned as control and were left untreated. Fifty days from first injection of cloprostenol, serum progesterone assay was carried out among the animals in Group I and II whereas the same was done among Group III bitches on day 90 after last breeding. Among Group I and II, mean serum progesterone concentrations were 0.93 ± 0.04 and 0.87 ± 0.01ng/ mL, respectively whereas the level was 1.72 ± 0.9 ng/mL among control group; highly significant difference (p<0.01) existed between control and treatment groups. The present study indicated that administration of PGF2? analogue during dioestrus enhances the pace of luteal regression among non-pregnant bitches.

IntroductionThe development and progression of hepatocellular carcinoma (HCC) is a multistage process involving the deregulation of genes that are crucial to cellular processes. Multiple risk factors are correlated with HCC. MicroRNA is differentially expressed in development of different types of malignancies, including hepatic malignancy. Single nucleotide polymorphisms (SNPs) are the most common sequence variation in human genome. SNPs in miRNAs may affect transcription, processing or target recognition and result in malignant diseases. Aim: To determine the association between micro-RNA gene polymorphisms and development of HCC in Egyptian Patients.Material and methodsThis study included 200 individual who were matched in age and sex. Tumor staging was done using BCLC staging system. Quantification and genotyping of Micro-RNA were performed.ResultsAmong the 200 patients, 2 groups were described: group I included 90 HCC patients with a male majority (72.2%) and 110 controls in group II. Diabetes and hypertension were detected as risk factors. Three microRNA SNPs were assayed. There was a significant association between rs10061133 miR-499b and the risk of HCC. The genotypes GG or G allele were associated significantly to an increased risk of HCC (GG: OR (95% CI) = 2.91 (1.23-4.22), p = 0.013; G allele: OR (95% CI) = 1.79 (1.12- 2.15), p = 0.026) compared with the genotype of AA or AG or A allele.ConclusionsThere is an association between the mi-RNA SNPs and the susceptibility to HCC, aiming to explore some roles and mechanisms of SNPs within miRNAs in the occurrence and development of HCC.

Purpose: to reveal the effect of different concentrations of prepared calcium hydroxide pastes (70%, 50%, and 30%) used in regenerative endodontic on microhardness and fracture resistance of radicular dentin. Material and methods: Different concentrations of calcium hydroxide (Ca(OH)2) were prepared with measured pH, then forty eight single rooted teeth were prepared and randomized into three groups according to Ca(OH)2 paste concentrations (12 samples each) and 12 samples were availed as control group. Group I: root canal contained 30% Ca(OH)2 paste. Group II: root canal contained 50% Ca(OH)2 paste. Group III: root canal contained 70% Ca(OH)2 paste. Samples were stored at 37 0C with 100% humidity for four weeks for subsequent microhardness and fracture resistance tests. Results: There was a statistically significant reduction of microhardness  and fracture resistance between test groups and control group (P≤ 0.05), group III showed a  significant reduction  in both microhardness and fracture resistance compared to group I. However, there was no significant difference in pH between different concentration of Ca(OH)2. Conclusion: Increasing concentration of Ca(OH)2 paste can negatively affect microhardness and fracture resistance of radicular dentin in revascularization procedure.

The purpose of our study is to determine the correlation between the effects of smoking, triglycerides and cholesterol (total, HDL, LDL) and periodontal disease. 90 patients, smokers diagnosed with periodontal disease and 30 nonsmoker patients (control group), in the age of 30-60 years, were studied. Patients were divided into 4 groups, each of 30 patients as follows: group I - smokers up to 10 cigarettes a day, group II-smokers between 10-20 cigarettes a day, group III-over 20 cigarettes a day, group IV- control group, nonsmokers. The values of the Silness-Loe dental plaque index (DPI), the gingival bleeding index (GI), the Periodontal Disease Index (PDI) -Ramfjord were noted in both the examined and control groups. The values of total cholesterol and HDL cholesterol showed statistically significant difference between the mean values �in the examined groups, while mean values �of HDL cholesterol in the second and third examined subgroups and control group were in higher range than the normal one. We concluded also that there is a relationship between smoking, the number of cigarettes smoked and the periodontal disease.

The present study was conducted to investigate the efficacy of Ovsynch and Ovsynch plus protocol in postpartum (day 60) Sahiwal cows (n=18). Animals were randomly divided into three equal groups, viz., Ovsynch group Ovsynch plus group and Control group. Animals of group I (n = 6) were treated with traditional Ovsynch protocol. The animals (n = 6) of group II were treated with Ovsynch plus protocol which consisted of an initial intramuscular injection of eCG (Folligon) @ 250 IU on day 60 postpartum followed 3 days later by GPG (Ovsynch) protocol. In group-III Control, no treatment was given to animals (n = 6). Treated animals were inseminated at a fixed time between 14 and 20 hrs after second GnRH injection, irrespective of estrus detection. Blood samples were collected from each animal on days 50 and 60 postpartum to determine the status of cyclicity in animals based on serum concentrations of progesterone (P4). A third blood sample was collected on the day of prostaglandin treatment to determine the response of first GnRH injection. Four animals each were cyclic, and two were acyclic in both treatment groups. Four animals each responded to first GnRH treatment in both treatment groups. Similarly, two animals each got conceived giving conception rate of 50% (2/4) in each treatment. In the control group, one out of 6 animals got conceived yielding 16.66 % conception rate (1/6) during the study period. It may be thus concluded that Ovsynch and Ovsynch plus protocol may be used during the early postpartum period to improve the reproductive efficiency in postpartum Sahiwal cows.

The serum progesterone and estradiol profiles during synchronization of estrus by buck effect and PGF2α treatments were monitored in Surti does. Total eighteen non-pregnant does selected were evenly divided into 3 groups, 6 does in each group. The does of Group I were teased with a sexuallyactive- apronized buck; and those of Group II were treated with PGF2α, i.e., Inj. Lutalyse® @ 7.5 mg/doe IM twice 11 days apart, while the Group III served as untreated control. Blood samples were collected from all the animals on day 0 (before 1st PGF2α injection), 3rd day (during treatment), 11th day (before 2nd PGF2α injection), 14th day (after treatment) and 40th day (post-service) by jugular vein puncture. The serum separated was stored at -20°C till further analysis. In all the three groups, 83.33% does, conceived at first service in the sampling cycle. The overall mean serum progesterone concentration of Group I does (5.82±0.72 ng/ml) was significantly higher (p less than 0.01) as compared to Group II (2.93±0.38 ng/ml) and III (2.88±0.30 ng/ml). Similarly, the overall mean serum progesterone concentration of Surti does on day 0 (2.65±0.46 ng/ml), 3rd (2.56±0.80 ng/ml), 11th (4.45±0.84 ng/ml) and 14th (3.40±0.63 ng/ml) did not differ significantly, but the overall mean level at day 40 (6.31±0.45 ng/ml) was significantly (p less than 0.01) higher, because most of animals became pregnant at that time. The overall mean serum oestradiol-17β levels of Group I (24.40±2.98 pg/ ml) was significantly higher (p less than 0.01) than in Group II (15.77±1.77 pg/ml) and III (12.21±1.45 pg/ ml). On the other hand, the overall mean serum oestradiol-17β levels of Surti does on day 0 (12.89±1.21 pg/ml), 3rd (15.84±1.74 pg/ml), 11th (14.81±1.96 pg/ml), 14th (22.15±2.97 pg/ml) and 40th (21.64±5.16 pg/ml) did not differ significantly (p>0.05) and the slightly higher overall mean level found at 40th day might be the influence of the non-pregnant does at first service in the cumulative animals. The hormonal profile reflected the initiation of cyclicity and establishment of pregnancy in treated and control animals.

Objective This study aimed to assess whether cord blood carboxyhemoglobin (COHb) levels in jaundiced term neonates with and without a positive direct Coombs test (DCT) and in healthy controls could be used as a predictor of severe hyperbilirubinemia. The percentage of cord blood COHb should be higher among neonates with Coombs-positive ABO hemolytic disease than among those with Coombs-negative ABO incompatibility and higher than that of ABO-compatible control neonates. Study Design This cross-sectional descriptive study of 198 term neonates comprised three subgroups: group I featured 68 DCT-positive ABO-incompatible neonates (ABO + DCT), group II featured 60 DCT-negative ABO-incompatible neonates with hyperbilirubinemia (ABO–DCT), and group III featured 70 healthy controls. COHb was determined by an OSM3 hemoximeter. Results Group I differed from groups II and III for cord blood bilirubin, cord blood hemoglobin, and cord blood hematocrit. Groups I and II had higher mean total serum bilirubin (TSB) levels than group III, while there was no difference in the mean TSB levels between groups I and II. There was no significant difference between the COHb group means for groups I, II, and III (p = 0.98). The area under the receiver operating characteristic curve calculated for group I/group III and group II/group III were found to be 0.62 and 0.54, respectively. Conclusion COHb levels did not prove to be superior to the DCT for predicting the risk of developing severe hyperbilirubinemia in term neonates. Key Points

Objectives To compare the clinical outcomes of patients undergoing additional procedures in endoscopic endonasal dacryocystorhinostomy (End-DCR) surgery and discuss the factors affecting the success of End-DCR surgery in light of relevant literature. Methods The study included 155 patients who underwent End-DCR surgery in our clinic due to epiphora. This was a prospective randomized, single-blind, controlled trial. Group I (control) included 54 patients who did not undergo silicone stent insertion or silver nitrate application, group II included 51 patients who underwent silicone stent insertion only, and group III included 50 patients who underwent silver nitrate application only. Statistical analysis was performed on follow-up data regarding anatomic and functional success rates. Results Revision surgery was performed in 16 patients who developed persistent epiphora in the postoperative period, including 6 in group I, 7 in group II, and 3 in group III ( P = .4). The most common reason for revision surgery was stenosis of the neo-ostium ( n = 8), followed by granulation tissue formation ( n = 5) and synechia formation ( n = 3). Granuloma formation was the most common postoperative complication, and a significant difference was found among the groups with regard to granuloma formation ( P = .04). At postoperative month 12, the functional success rate was estimated to be 88%, 86%, and 94%, and the anatomic success rate was estimated to be 94%, 92%, and 96% in groups I, II, and III, respectively, with no significant difference, found among the 3 groups with regard to both rates ( P = .79 and P = .76, respectively). Conclusion The results indicated that stenting and silver nitrate application did not affect surgical success. Our preliminary results on silver nitrate cauterization showed that it is an effective, inexpensive, and practical method to reduce granulation formation in the postoperative period.
