Abstract: Background: Hepatocellular carcinoma (HCC) is known to cause significant public health problems; treatment is effective in the early phases of the disease. Unfortunately, HCC is still diagnosed at an advanced stage. Recently, circulating microRNAs (miRNAs) have been accounted to be promising biomarkers for diagnosing cancers. This study was conducted to evaluate the feasibility of using serum miR-150 and miR-130b in the early diagnosis of HCC. Methods: The expression of miR-150 and miR-130b was evaluated using a quantitative real-time RT-PCR in 203 serum samples (60 healthy individuals, 43 cirrhotic and 100 HCC patients). Results: Serum miR-150 levels were significantly reduced in HCC patients, compared to healthy controls (P < 0.0001) and cirrhotic patients (P <0.0001), while miR-130b was significantly increased in HCC patients, compared to healthy controls (P < 0.0001) and cirrhotic patients (P < 0.0001). Serum miR-150 levels were down-regulated in cirrhotic group compared with healthy control (P=0.334) while miR-130 was significantly up-regulated in cirrhotic patients group compared with healthy control (P <0.0001). Receiver operating characteristic curve (ROC) analyses suggested that serum miR-150 and miR-130b had significant diagnostic value for HCC. Conclusion: Serum miR-150 and miR-130b can serve as a minimally invasive biomarker for the possible early diagnosis of HCC, and to differentiate it from the cirrhotic patients.

Abstract: Purpose: We evaluated the therapeutic efficacy and survival of combination of percutaneous radiofrequency ablation (RFA) and percutaneous ethanol injection (PEI) for focal hepatic tumors 3-5 cm in diameter in patients with inoperable hepatocellular carcinoma (HCC). Patients and methods: Forty patients(29males and 11 females, median age 56.5 years, range 42-70 years) with single inoperable HCCs medium sized lesions 3-5cm in the longest diameter; Performance status according to eastern cooperative oncology group (ECOG) 0-2, with Child Pugh class A or B; All were randomized into 2 treatment arms; group A; Included 20 patients, who have received combined ultrasound guided local ablative cool-tip RF and PEI, and group B; Included 20 patients, who have received PEI only. All patients were followed up 4 weeks after the end of the ablative sessions by helical dynamic computed tomography for assessing the therapeutic response. 1, 2 year overall survival rates (OSR) and progression free survival rates (PFSR) were recorded. Results: The complete necrosis rate of lesions was (80%) for group A versus (65%) for group B; with no statistical significance difference (P >0.05). The 1, 2 year OSR were (75%), (55%) in group A vs. (60%), (40%) in group B, the 1, 2 PFSR were (60%), (45%) in group A vs. (45%), (25%) in group B with no statistical significance difference (P >0.05). The complications were tolerable and limited to pain, vomiting, liver abscess and bile duct dilatation. Conclusion: The combination of percutaneous radiofrequency ablation (RFA) and percutaneous ethanol injection (PEI) for focal hepatic tumors 3-5 cm was effective and safe with prolongation of survival in patients with inoperable hepatocellular carcinoma (HCC), with minimal tolerable complications.

Abstract: It is true that animals are used in a variety ways of in biological and biomedical research. The contributions of animal research to medical science and human health are undeniable. Scientific expertise, consensus and facts on the use of animal research must be weighed accordingly to have a honest, public discussion. Animal experimentation is necessary for scientists and different researchers at the current level of knowledge for studying the pathogenesis of different disease undertake drug trials, generate a variety of biological such as immunodiagnostics, vaccines to alleviate suffering in the human and animals themselves. Animals that are used for investigation and qualification of experiments and biomedical research are the base for different purposes of scientific studies we must use in a responsible and reasonable manner with no stress, pain and discomfort when we conduct studying with them based on the role and regulation of ethical arguments.

Abstract: Background: Altered microRNAs (miRNAs) expression has an impact on cancer initiation and progression. There is an emerging evidence that circulating miR21 and miR34a may have a potential role in breast cancer (BC) diagnosis and prognosis. Aim of the work: The current study aimed at characterizing the expression pattern of miR21 and miR34a in BC female patients pre- and post chemotherapy and delineating their correlation with clinicopathological subtypes and other molecular biomarkers. Patients and Methods: Real time quantitative polymerase chain reaction (RQ PCR) was used to assess the relative expression of miR21 and miR34a in sera of 179 BC female patients in relation to 58 healthy females. Results: Circulating miR21 and miR34a showed significant upregulation of 5.1 fold change (p<0.001) and downregulation of -5.63 fold change, respectively (p<0.001). Data showed higher levels of miR21 in triple negative (TN), basal like subtype and stage III BC patients (p<0.001). Higher miR34a expression was demonstrated in triple positive, luminal A & B subtypes and stage I & II BC patients (p<0.001). MiR21 was directly correlated with Bcl2 level (p<0.001). There was direct correlation between miR34a, BRAC1, BRAC2 & p53 (p<0.001). MiR21expression decreased significantly postchemotherapy (p<0.001). A significant increase in miR34a level was detected after chemotherapy (p<0.001). Conclusion: Our data suggest a potential role of circulating miR21 and miR34a as molecular biomarkers in BC.

Abstract: Background: There is sufficient evidence that the apo B-100 and apo A-I are as accurate indicators in the prediction of atherosclerotic vascular disease in the diabetic patients. EPA has the antioxidant, antiinflammatory, antithrombogenic, and antiarteriosclerotic properties. Therefore, we investigated the effect of EPA supplementation on the serum levels of apo B-100, apo A-I and apo B-100/apo A-I ratio in the diabetic patients. Methods: This study was designed as a randomized, double-blind, and placebo-controlled clinical trial. Thirty six patients with type 2 diabetes were given written; informed consent, randomly were classified into 2 groups. They were supplemented with 2 g/day of the capsules of EPA or placebo. Blood sample for measurement of the serum levels of apolipoproteins and lipids, as well as FBS and HbA1c were given. Results: There were no significant differences between the two groups regarding any demographic, clinical or biochemical data, total energy intake, and macronutrient intake at the baseline, and during the intervention, except for a significant increase of HDL-c and apo A-I, and a significant decrease in the serum levels of apo B-100 and apo B-100/apo A-I ratio, as well as a slight reduce of TC, LDL-c, TG and FBS in the supplement group. Conclusions: EPA is atheroprotective via increase in the serum levels of apo A-I, and decrease in the serum levels of apo B-100 and apo B-100/apo A-I ratio, as well as change in the serum levels of lipids, and FBS.

Abstract: The present work aimed to evaluate the anticancer and antiviral potentials of Pomegranate (Punica granatum) peel extract (PPE). Data recorded revealed that PPE was Cytotoxic to cancer cells in a concentration and cell type dependent manner, where the HEp-2 cells were more sensitive to the tested extract than PC-3 recording a significantly reduced IC50 value (P<0.05) in HEp-2 than PC-3 with records 115 and 206 g / ml respectively. Also, the anticancer activity was assured via the up/down regulation of pro-apoptotic gene (Caspase-3) and metastasis contributing gene (MMP-1), both genes expression was cell type dependent as well. Also, the apoptotic potential of PPE was confirmed via arresting of cells in the G2/M phase and elevated apoptotic cell % in the pre-G1 phase. Also, the initiation of PPE antiviral potential was confirmed by monitoring the MxA gene post Vero cell treatment for 24 hours as the expression of MxA gene was significantly elevated (P<0.05) than non treated cells used as control.

Abstract: Several second-generation androgen receptors signalling inhibitors have been used in management of patients with castration resistant prostate cancer (CRPC). In this work, we aimed to retrospectively study the efficacy and tolerability of the antiandrogen enzalutamide in a cohort of CRPC patients who were treated in our centre between June 2014 and December 2015. Thirty six patients were included; 28 (77.8%) had metastatic prostate cancer at initial presentation and 8 (22.2%) had non-metastatic disease but relapsed later on during follow up. Prior to enzalutamide, most patients (52.8%) had 3 lines of hormonal treatment. Eleven patients (30.6%) received docetaxel chemotherapy. Overall, 27 patients (75%) responded to enzalutamide. The median progression free survival (PFS) duration was 5 months and 1 year PFS probability was 37.5%. The median overall survival (OS) duration since starting enzalutamide was 14 months and 1 year OS is 52%. Enzalutamide was well-tolerated by most patients and offered control of CRPC for a reasonable period of time.

Abstract: Cancer treatment is one of the main challenges that face the scientific centers all over the world. The cancer incidence percentage increases year after year. The most used treatment for cancer is chemotherapy which is an application of systemic cytotoxic drug inside the patient. There are two main problems in chemotherapy that the cytotoxic drug is given systematically and cannot be localized in the tumor region in most cases that lead to killing the cancer cells as well as normal cells; and that cause the chemotherapy side effects like anemia, decrease in all blood cells count and platelets, nausea, vomiting, diarrhea, hair and nails loss and may cause a kind of blood toxicity. Photodynamic therapy (PDT) is a relatively new approach for the treatment of malignancies with only minimal side effects for the patient. It is based on the administration of a tumor-localizing dye (photosensitizer, PS) that becomes toxic to neoplastic cells when is activated by light (usually from a laser) at a specific wavelength in the presence of O2. In this work photodynamic therapy modality was used. Porphyrin derivative was used as a photo sensitizer drug and one source of energy were used; namely infrared laser with three frequency levels (1000, 2000, and 3000 Hz). Tumor- bearing animals were divided into the following groups each of 10 animals. The 1st group consists of two control groups: the 1st one was untreated group and the 2nd one was injected with photosensitizer alone. The 2nd group consists of 30 mice divided into 3 sub-groups and tumor site was irradiated with laser light as follows:1000 Hz, 2000 Hz and 3000 Hz for 5 min.3rd group consists of 30 mice injected with HPD 12.5 mg/Kg, then divided into 3 subgroup and tumor site was irradiated with laser light at the same conditions of 2ndgroup. The results show decrease in tumor size treated with drug (HPD) which is used as a photo sensitizer, laser, and combined treatment, both in the presence and absence of photosensitizer. Combined treatment is more effective on tumor cells than using of laser and drug alone. Also the presence of photosensitizer increases the effect of laser on tumor size. However, from histopathology of ehrlich tumor using 3000Hz of laser irradiation in the presence of the photosensitizer drug approximately has the most effect than using the photosensitizer drug alone and exhibit totally necrotized tumor. It could be concluded that the use of the photosensitizer drug alone has no effect on the ehlrich tumor. However, the presence of the drug gave maximum effects with exposure to 3000 Hz infrared laser irradiation. The work needs to be extended to reach more and powerful effects using the photodynamic therapy with exposure to other different energies of infrared laser radiation.

Abstract: Aloe-emodin is a Hydroxyanthraquinone that exists in Aloe Vera leaves and has been known to have anti-tumor effects. Various studies have mentioned the biologic effects of Aloe Vera such as antiviral, antimicrobial and some hepato-protective effects. Recently its antitumor effects have attracted many researchers. Breast cancer is the most common malignancy in women, accounting for 30% of all female cancers and < 1% of all cancer cases in men. Breast cancer also is responsible for 15% of cancer deaths in women. The aim of the present study was to investigate the anti-cancer effect of aloe-emodin on human breast cancer MCF-7 cell line. Materials and Methods: MCF-7cells were cultured in RPMI medium with 10% fetal bovine serum (FBS). The cytotoxic effect of different concentrations (5, 10, 25, 50, and 100 M) of Aloe-emodin on cultured cells were evaluated by MTT assay at different times (24, 48, 72 h). Apoptosis and CD95 (Fas) expression were analyzed by flow-cytometry using an Annexin V-FITC/PI kit and Fas (CD95) kit according to the manufacturer’s protocol. Results: Aloe-emodin decreases the viability of MCF-7 cell line in a time and dose dependent manner, so that the most effective concentration of this substance was 100M and 72h after treatment. According to the data of Fas (CD95) expression and Annexin-PI, the highest apoptosis induction rate was seen in 100M and 72 h. Conclusion: The findings of the present study indicated that Aloe-emodin has some antitumor effects and can be used in the treatment of breast cancer. However, further investigation of its cytotoxic effects against tumor cells, both in vitro and in vivo, is recommended.

Abstract: Disease diagnosis and prognosis are two medical applications pose a great challenge to the researchers. The application of data mining and machine learning techniques has revolutionized the whole process of disease diagnosis. This paper intends to propose a hybridized approach, Correlative Framework (CF) algorithm for the implementation of diagnosing breast cancer, the most scare away disease. The major objective of this paper is to analyze and predict the vulnerability of disease in a patient. The association rule of data mining is deployed to correlate the interesting relation from the huge medical database. In this proposal, Linear Discriminant Analysis (LDA) is exploited for feature selection. Initially, base rule is generated, then for each rule feature support is computed which is followed by confidence. On the basis of feature supporting the base rule, supplementary rule and positive rule is generated. Regression is utilized for each rule with its corresponding feature value. Classification result is obtained based on minimum and maximum of residual support values. The significant performance of our newly devised algorithm is evaluated using confidence metrics. Experimental results expose that prediction level of our adduced work is more factual than other existing algorithms.

Abstract: Objective: To detect the change of c-Met and c-Src expression and activity in human lung cancer cells after radiation in order to explore the efficacy of them and the mechanism. Methods: We used human lung cancer cell lines A549 in vitro as research object. Western Blot assay was used to evaluate the change of c-Met and c-Src expression and activity in human lung cancer cells in different time point after 8Gy irradiation and before. Results: Western Blot results showed that the phosphorylation-c-Met reach the peak after 8Gy X-ray acting on A549 cell lines 2 hours. It’s 4.41times as many as the expression of before irradiation. It marked increased the activation of c-Met. The expression of non-phosphorylation c-Met is undifferentiated. The phosphorylation-c-Src reach the peak after 8Gy X-ray acting on A549 cell lines 4 hours. It has increased 2.99 times than those who not receive irradiation. The expression of non-phosphorylation c-Src is undifferentiated. Conclusion: The results of this research provide foundation for further exploring the mechanism of radiosensitizing effect in non small cell lung cancer and reference for whether c-Met or c-Src inhibitor can be used to prevent the radiosensitizing effect in clinical application for the patients who have non small cell lung cancer.
