The study inc1uded 50 tissue blocks embedded in paraffin wax (16 females and 34 males), obtained from a patients group with (CRC) colorectal cancer , as well as 35 Tissue blocks that were embedded in paraffin wax from norma1 co1on (ulcerative co1itis) as controls. A relatively few oncogenes and most prominently tumor-suppressing genes, Kirastien rat sarcoma virus (KRAS), and P53 genes have been mutated into a significant part of CRCs, and a broad collection of mutated genes has been defined in CRC subsets. Current findings showed very significant differences between patients and control subjects in the p53 positive rate (P<0.001). TP53 Pro/Pro genotype positivity was higher in the contro1 group I than in the patient group I and this was a significant difference (Pi<0.001) with an odd ratio of less than one. The genotype Pro/Pro was considered to be protective against colorectal carcinoma preventively fractured 0.767. The positive rate of p53 Arg/Arg genotype in patients was more frequent and statistically significant (P <0.01), because the odd ratio was more than one. The genotype Arg/Arg would be considered a colorectal carcinoma risk factor. We conclude that p53 over expression is used as an indicator of p53 mutation (as identified by immuno-historic chemistry) and KRAS protein expression was negatively impaired for all the patients in the current study.

Purpose: To determine the levels of Vitamin D in children with myopia and to compare them with age matched controls. Study Design:  Case control study. Place and Duration of Study:  The study was conducted in Naseer Memorial Hospital, Dadhyal Azad Kashmir from March 2016 to March 2017. Material and Methods:  Two hundred patients were selected using convenient sampling technique and were divided two groups (group I Myopic and group II control). Myopia was labeled if after subjective refraction a Spherical Equivalent (SE) of −0.50 diopters (D) or more was found. Vitamin D levels were measured by radioimmunoassay technique with Diasorin SR® kit following the user’s manual. Vitamin D levels less than 20 ng/ml were considered Vitamin D deficient following the standards of American academy of pediatrics. The collected data was entered in the statistical package for social sciences (SPSS) version 21 for analysis. Independent t–test was used to determine the significant difference of means between controls and patients. P-values less than 0.05 were considered significant. Results:  Mean age of controls and myopes were 10.65 ± 3.9 and 10.20 ± 2.5 years respectively. Vitamin D levels in myopic children were found to be 14.95 ± 3.75 ng/ml and there was no significant difference in mean values of Vitamin D levels in myopic and control group. Conclusion:  We found no difference in Vitamin D levels of myopic and non myopic children and concluded that Vitamin D has no role in development or progression of myopia.

SUMMARYEating raw pork and/or liver is a custom of the Bai ethnic group in China. Most people living in Dali Bai Autonomous Prefecture, Yunnan Province, southwestern China are of Bai ethnicity. Little is known of the seroprevalence ofToxoplasma gondiiin Bai and Han ethnic populations in this region. In the present survey, a total of 555 and 595 blood samples were obtained from Bai and Han ethnic groups in Dali urban and rural areas, respectively. Enzyme-linked immunosorbent assay was performed to examineT. gondiiIgG antibodies. Total positive rate of anti-T. gondiiIgG in Bai and Han groups in this region was 21·6% (248/1150). The total seroprevalence ofT. gondiiwas significantly higher in the Bai ethnic group (32·3%, 179/555) than in the Han ethnic group (11·6%, 69/595) (P < 0·01). The results of statistical analysis indicated that there was no significant difference between cat feeding/non-cat feeding groups in the Bai ethnic group, the most important risk factor was consumption of raw pork and/or liver for the Bai group, but feeding a cat may be the main route ofT. gondiiinfection for the Han group. Therefore, it is essential to implement integrated strategies to prevent and controlT. gondiiinfection in this unique region of the world.

Background of the study: Immunizations cause distress in children due to its acute pain. Younger children are particularly in need of intervention because they report more pain and display more behavioral distress during painful procedures. One of the effective non-pharmacological interventions of acute management is comfort position given by the parent. Comfort position provided by the parent during immunizations has been demonstrated to be useful in infants, toddlers and pre-school children. Yet, this simple intervention is not used on a routine basis. Aim: The aim of the study was to compare the impact of sitting and supine position on behavioral distress during immunization among children (1-3 years) in selected immunization clinics. Objectives of the study: To determine the impact of sitting position on behavioral distress of children receiving immunization (Group I - experimental group). 1. To determine the impact of supine position on behavioral distress of children receiving immunization (Group II - control group). 2. To compare the impact of sitting and supine position on behavioral distress of children during immunization. Methods: The research design adopted for the study was post test only control group design. Immunization clinic selected based on the convenience of the investigator. Purposive sampling technique used to select the sample and the sample were assigned randomly in to Group I(experimental group) and Group II(control group).To assess the impact of position: PBRS-R was used to assess the behavioral distress of children during immunization injection. Results: The collected data was analyzed by descriptive and inferential statistics. 1. Assessment of behavioral distress scores during immunization injection showed significant difference in mean scores in Group I (16.4±2.30) and in Group II (28.45±2.59). 2. Comparison of behavioral distress scores in Group I and Group II showed that there is a significant difference (p<0.05) in behavioral distress between experimental (Group I) and control (Group II) group. 3. Item wise comparison of behavioral distress scores in Group I and Group II showed that there is no significant difference(p<0.05) in behavioral distress between experimental (Group I) and control (Group II) group. Interpretation and conclusion: Findings of the study revealed that the comfort position, i.e., sitting position was effective in reducing behavioral distress during immunisation. Hence, paediatric nurses ought to promote the use of comfort position to reduce behavioral distress associated with painful procedure.

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.

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.

Objective: Catheter management is conducted to the patients undergoing transurethral resection of the prostate (TURP). There were many arguments between clinical practitioners about bladder training procedure after TURP procedure. This study aims to determine whether there is a relationship between bladder training action and success of spontaneous micturition in post TURP procedure in patients with urinary retention caused by prostate enlargement. Material & methods: Randomized clinical trial was conducted at Kardinah General Hospital, Tegal from October 2015 to February 2016. 44 study participants who underwent TURP were randomly allocated into two groups. In Group I, patient’s Folley catheter was clamped prior to its removal (bladder training group); and in Group II was not clamped (control group). Results: Mean age of patients was 64.48 ± 8.1 years old. There were 23 patients (52.3%) have had history of recurrent urinary retention and 21 patients (47.7%) have had not (p=0.560). There were 4 patients (17.4%) in Group I and 1 patient (4.7%) in Group II who required re-catheterization and discharge with catheter. There was no statistically significant difference in spontaneous micturition rate between bladder training group and control group (p=0.187).  Conclusion: The result of the current study identified that bladder training to patients undergoing TURP procedure had no significant impact in spontaneous micturition.

Abstract Osteosarcoma (OS) patients often exhibit pulmonary metastasis, which results in high patient mortality. Our present study established the doxorubicin (Dox) resistant human OS MG-63 and HOS cells and named them MG-63/Dox and HOS/Dox, respectively. The Dox resistant OS cells had greater invasion ability than that of parental cells. The expression of ZEB1, while not FOXM1, Snail, HIF-1α, or Sp1, was significantly increased in Dox resistant OS cells. Silencing of ZEB1 can attenuate the metastasis and increase Dox sensitivity of MG-63/Dox and HOS/Dox cells. The upregulation of ZEB1 can increase of the expression of interlukin-6 (IL-6). Anti-IL-6 inhibited the invasion and increase the Dox sensitivity of MG-63/Dox and HOS/Dox cells. There was no significant difference of ZEB1 mRNA between Dox resistant and control cells. The upregulation of ZEB1 in Dox resistant OS cells can be attributed to the increase of protein half-life. This was confirmed by results that the inhibitor of proteasomal degradation can increase ZEB1 in Dox resistant OS cells. Over expression of SIAH1 can inhibit the expression of ZEB1 and increase the Dox sensitivity of MG-63/Dox and HOS/Dox cells. Collectively, we confirmed that SIAH1 induced ZEB1 is involved in the Dox resistance of OS cells.

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.

Introduction: Ocimum basilicum (OB), a herb known for its antihypertensive, anticholinesterase and antioxidant properties was investigated for possible intraocular pressure (IOP) lowering effects in rabbits with ocular hypertension (OHT). Methods: The IOP lowering effect of a single drop of OB extract (OBE) was evaluated in oculonormotensive rabbits using three concentrations (0.25, 0.5 and 1% w/v). The concentration showing maximum IOP reduction was further evaluated in rabbits with water-loading and steroid-induced OHT. Results: IOP lowering effect of OBE 0.5% in oculonormotensive rabbit eyes was significantly greater compared to OBE 0.25% (p<0.05) but was comparable (p>0.05) to OBE 1%. Therefore, 0.5% concentration was selected for further evaluation. Pretreatment with OBE (0.5%) caused significantly lower increase in IOP after water loading amounting to 23.39% above baseline as compared to 54.00% in control eye, 15 minutes post water loading. At 60 minutes, post water loading, mean IOP rise was 95.12% and 63.58% in control and test eyes, respectively. Significant difference between the mean IOP of two eyes persisted during the 2nd hr. In rabbits with steroid induced OHT, OBE 0.5% produced a mean IOP reduction of 24.73% at the end of first hr and the mean peak IOP reduction of 31.63% was observed at the end of 2 hr. A significant difference between the IOP of test and control eyes persisted from 1 to 6 hr. Conclusions: Ocimum basilicum seed extract showed significant IOP lowering effect in rabbits with water loading and steroid induced OHT, however, its utility as an effective antiglaucoma medication needs further investigations.
