Abstract Background:Oral cancer is considered a major public health problem due to its high mortality and morbidity rates. Survival rate of OSCC can be significantly improved by using non -invasive tool such as salivary biomarkers for detection of OSCC which is considered a promising approach. Cathepsin B is a lysosomal cysteine protein, which is present in abundant quantities in lysosome of cells, tissues and different biological fluids. Increased expression of Cathepsin B is observed in many malignancies including oral cancer. The present study was designed to determine the salivary levels of Cathepsin B in different histological grades of OSCC.Method:In this study total no of 80 research participants were enrolled which were divided into four groups. Each group comprises 20 participants. Groups 1 comprises 20 patients of OSCC (Well differentiated), Group 2 comprises 20 patients of OSCC (moderately differentiated), Group 3 comprises 20 patients of OSCC (poorly differentiated|) and Group 4 comprises 20 healthy controls. Saliva sample was collected from all the four study group and salivary Cathepsin B levels were analyzed by ELISA sandwich technique in duplicate.Results:Salivary levels of Cathepsin B are significantly increased with p- value (<0.001) in patients of OSCC in comparison to control group. We observed highest mean Cathepsin B levels in well differentiated OSCC followed by poorly differentiated OSCC and moderately differentiated OSCC.Conclusion:Results of the present study suggests that Cathepsin B has a great value as a salivary biomarker for diagnosis and monitoring of OSCS in different histological grades of OSCC. It could increase the survival rate and further improve the prognosis of OSCC.

BACKGROUND Gastric cancer accounts for 2.7% of all newly diagnosed cancer cases in Jordan. OBJECTIVE The aim of this study was to calculate the survival rate and its determinants among Jordanian patients who were diagnosed with gastric cancer between 2010 and 2014. METHODS A descriptive study was conducted based on secondary analysis of data from the Jordan Cancer Registry during the period of 2010-2014. Only cancer-related deaths were recorded as “death” in the survival analysis. RESULTS A total of 1388 new cases of gastric cancer were recorded between 2010 and 2014. Of these, 872 (62.8%) were Jordanians and 60.5% were males. The mean age at diagnosis was 58.9 years and the median follow-up time was 1.6 years. The 5-year survival rate decreased significantly from 89% in patients with well-differentiated cancer to 32% in patients with poorly differentiated cancer (<i>P</i>=.005). The overall 5-year survival rate was 37.7% and the median survival was 1.48 years (95% CI 1.179-1.783). The 5-year survival rate decreased significantly with increasing age and with advanced stage of the disease: the 5-year survival rate was 75% for localized-stage, 48% for regional-stage, and 22.7% for distant-metastasis disease (<i>P</i>=.005). CONCLUSIONS This study showed that the overall 5-year survival rate among patients with gastric cancer in Jordan between 2010 and 2014 was 37.7%, which is higher than the reported rates from different countries in the Eastern Mediterranean region such as Egypt.

Cyclin D1 expression was positive in 35 cases of oral cancer with a Cyclin D1 positivity of 22.16?22.18. The percentage of positive cases as well as Cyclin D1 positivity showed an increase as the grade of differentiation advanced. No significant association was found between Cyclin D1 positivity and degree of differentiation of tumors (p=0.138). A significant difference in Cyclin D1 positivity was observed (p=0.043) comparing well differentiated (16.61?17.89) and poorly differentiated (37.0?32.51) tumors, as well as between well differentiated (16.61?17.89) and moderately differentiate tumors (24.38?21.93; p=0.002). Similarly, significant difference in Cyclin D1 positivity was observed comparing moderately differentiated (24.38?21.93) and poorly differentiated tumors (37.0?32.51; p=0.043). Cyclin D1 expression was more frequently seen in hard palate (75%), buccal mucosa (67%) and lip (60%) while expression of Cyclin D1 was less frequent in sites like gingiva (0%), tongue (40%) and floor of mouth (43%). There was no association between Cyclin D1 expression and primary site of oral cancer (p=0.528) in tobacco and betel quid chewers of northern India.

In Acute Lymphocytic Leukemia motility of lymphocytes is associated with dissemination of malignancy and establishment of metastatic foci. Normal and leukemic lymphocytes in circulation reach solid tissues where due to in adequate perfusion some cells get trapped among tissue spaces. Although normal lymphocytes reenter into circulation leukemic lymphocytes are thought to remain entrapped owing to reduced mobility and form secondary metastasis. Cell surface, transmembrane interactions, cytoskeleton and level of cell differentiation are implicated in lymphocyte mobility. An attempt has been made to correlate ultrastructural information with quantitative data obtained by Laser Doppler Velocimetry (LDV). TEM of normal & leukemic lymphocytes revealed heterogeneity in cell populations ranging from well differentiated (Fig. 1) to poorly differentiated cells (Fig. 2). Unlike other cells, surface extensions in differentiated lymphocytes appear to originate by extrusion of large vesicles in to extra cellular space (Fig. 3). This results in persistent unevenness on lymphocyte surface which occurs due to a phenomenon different from that producing surface extensions in other cells.

Background and aim: HER2 overexpression by immunohistochemistry is a prognostic maker in gastric cancer and helps to select candidates benefitted from targeted therapy with trastuzumab. This study is aimed at the assessing HER2 overexpression and its relationship with endoscopic and histopathological findings of gastric adenocarcinoma. Objectives and methods: Biopsy samples from 92 gastric cancer patients were examined for HER2 status by immunohistochemical staining. Results: 6.5% of tumors were cardia tumors and 93.5% were non-cardia tumors. Using the Lauren classification, 51.1% were intestinal type and 48.9% were diffuse type. Using WHO classification, 54.3% were tubular adenocarcinoma, 7.6% were mucinous adenocarcinoma, 15.2% were signet-ring cell carcinoma, and 22.8% were undifferentiated carcinoma. 32.6% were well-differentiated, 15.2% were moderately-differentiated, and 52.2% were poorly-differentiated carcinoma. HER2 was positive in 20.7% of gastric carcinomas, 50% cardia tumors and 18.6% non-cardia tumors. HER2 positivity among polypoid, fungating, ulcerated, and infiltrative types were 38.5%, 29.7%, 9.1% and 0%, respectively. HER2 overexpression in intestinal type was higher than that in diffuse type (31.9% vs. 8.9%, p = 0.009). HER2 overexpression in tubular adenocarcinoma, mucinous adenocarcinoma, signet-ring cell carcinoma, and undifferentiated carcinoma was 28.0%, 14.3%, 7.1% and 14.3%, respectively. HER2 overexpressions were different between differentiation degrees: 30% of well-differentiated tumors, 35.7% moderately-differentiated tumors, and 10.4% of poorly-differentiated tumors (p = 0.037). Conclusions: HER2 overexpression was found in 20.7% of endoscopic biopsy sample of gastric adenocarcinoma and was associated with endoscopic gross characteristic, Lauren histologic type and differentiation degree.

Background: microRNAs play a critical role in auto-immunity, cell proliferation, differentiation and cell death. miRNAs are present in all biological fluids, and their expression is essential in maintaining regular immune functions and preventing autoimmunity, whereas miRNA dysregulation may be associated with the pathogenesis of autoimmune and inflammatory diseases. Oral lichen planus (OLP) is an inflammatory disease mediated by cytotoxic T cells attack against epithelial cells. The present study aims to perform a specific microRNA expression profile through the analysis of saliva in this disease. Methods: The study group was formed by five patients (mean age 62.8±1.98 years; 3 females/2 males) affected by oral lichen planus and control group by five healthy subjects (mean age 59.8 years±2.3; 3 females/ 2 males); using a low-density microarray analysis, we recorded a total of 98 differentially expressed miRNAs in the saliva of patients with oral lichen planus compared to the control group. The validation was performed for miR-27b with qRT-PCR in all saliva samples of oral lichen planus group. Results: 89 miRNAs were up-regulated and nine down-regulated. In details, levels of miR-21, miR- 125b, miR-203 and miR15b were increased (p<0.001) in study group while levels of miR-27b were about 3.0-fold decreased compared to controls (p<0.001) of miR-27b expression in OLP saliva. QRTPCR validation confirmed the down regulation of miR-27b in all saliva samples. Conclusions: Collecting saliva samples is a non-invasive procedure and is well accepted by all patients. microRNAs can be readily isolated and identified and can represent useful biomarkers of OLP.

BACKGROUND Diabetes mellitus is currently a major public health problem worldwide. It is traditionally approached in a clinical inpatient relationship between the patient and the healthcare professional. However, the rise of new technologies, particularly mobile applications, is revolutionizing the traditional healthcare model through the introduction of telehealthcare. OBJECTIVE (1) To assess the effects of mobile applications for improving healthy lifestyles on the quality of life and metabolic control of diabetes mellitus in adult patients. (2) To describe the characteristics of the mobile applications used, identify the healthy lifestyles they target, and describe any adverse effects their use may have. METHODS Review of systematic reviews and meta-analysis, following the guidelines of the Cochrane Collaboration and the Joanna Briggs Institute. We included studies that used any mobile application aimed at helping patients improve self-management of diabetes mellitus by focusing on healthy lifestyles. Studies needed to include a control group receiving regular care without the use of mobile devices. In May 2018, a search was conducted in Medline, Embase, Cochrane, LILACS, PsychINFO, Cinahl and Science Direct, updated in May 2019. The methodological quality of the studies was assessed using the Amstar-2 tool. RESULTS Seven systematic reviews of 798 articles were initially selected for analysis. The interventions had a duration of between 1 and 12 months. Mobile applications focused singly or simultaneously on different lifestyles aspects (diet, physical exercise, motivation, blood glucose levels, etc.). There are significant changes in HbA1c values, body weight and BMI, although in others, such as lipid profile, quality of life, or blood pressure, there is no clear improvement. CONCLUSIONS There is clear evidence that the use of mobile applications improves glycemic control in diabetic patients in the short term. There is a lack of evidence in its long-term benefits. It is thus necessary to carry out further studies to learn about the long-term effectiveness of mobile applications aimed at promoting the healthy lifestyles of diabetic patients.
