Abstract
Gastrointestinal nematodes (GINs) are serious issue for health of wild sheep kept in captivity. Chemically synthesized anthelmintics are regularly used to control these parasites. In recent years anthelmintic resistance and remnant of drugs in animal products leads to use of medicinal plants as alternative to anthelmintics. In current study, the efficacy of aqueous, methanolic and ethanolic dried leaf extracts of medicinal plants Moringa oleifera and Azadirachta indica were tested for in vitro ovicidal and larvicidal activities against Haemonchus, Trichuris, Coccidia and Trichostrongylus; naturally acquired nematodes isolated from wild sheep (Ovis orientalis orientalis). Six concentrations of these plants extract (1.56, 3.13, 6.25, 12.5, 25 and 50 mg/ml) were evaluated using egg hatching assay (EHA) and larval development assay (LDA) in three replicates. To compare treatment effects, untreated and treated (0.1% ivermectin) controls were used. The aqueous, methanolic and ethanolic leaf extracts showed anthelmintic activities against isolated genera of nematodes but the inhibition was maximum (99%) in ethanol extract of M. oleifera followed by methanol extract (97%) at maximum concentration tested at (50mg/ml). The overall findings of this study shows that Moringa oleifera and Azadirachta indica leaf extracts possess significant anthelmintic efficacy against GINs of sheep and these could be a natural alternative to synthetic anthelmintics to treat the worm infections in animals.

Abstract
Background Hepatocellular carcinoma (HCC) is one of the most prevalent types of cancer and is responsible for close to one million annual deaths globally. In Pakistan, HCC accounts for 10.7% of cancer incidence. Prior studies indicated an association between interleukin 4 (IL-4) and cytotoxic T lymphocyte protein 4 (CTLA-4) gene polymorphisms in many types of cancers, including HCC that are either hepatitis B virus (HBV)- or hepatitis C Virus (HCV)-induced. The association of IL-4 and CTLA-4 genetic polymorphisms with HCV-induced HCC is not yet determined in the Pakistani population. Therefore, this research is designed to investigate the implication of IL-4 and CTLA-4 gene polymorphisms by determining the association of IL-4 -590 C/T (rs2243250) and CTLA-4 + 49 A/G (rs231775) with HCC in Pakistan. Methods Different bioinformatics tools were employed to determine the pathogenicity of these polymorphisms. Samples were collected from HCV-induced HCC patients, followed by DNA extraction and ARMS-PCR analysis. Results The SNP analysis results indicated a positive association of IL-4 -590C/T and CTLA-4 + 49A/G gene polymorphisms with HCV-induced HCC in Pakistan. The CTLA-4 polymorphism might enhance therapeutic efficiency of HCC chemotherapy medicines. The IL-4 polymorphism might introduce new transcription factor binding site in IL-4 promoter region. Conclusion This study delineated risk factor alleles in CTLA-4 and IL-4 genes associated with HCV-mediated HCC among Pakistani patients that may have application to serve as genetic markers for pre- and early diagnosis and prognosis of HCC in HCV patients.

Abstract
Abstract
Background: Breast microcalcifications are the sole early stage diagnostic markers of breast cancer. The association of mineralization (especially type II microcalcifications) with both benign and malignant lesions often leads to unnecessary biopsies. The processes by which these ectopic microcalcifications form are unknown. In the current work, we attempted to explore the possibility of obtaining genes responsible for the formation of microcalcifications in breast cancer cell lines at cellular level and understand their potential involvement in disease progression and distant metastases.
Methods:The GEO dataset GSE16795 used in this study contains gene expression profiles of 28 human breast cancer cell lines that were divided into two groups - metastatic and non-metastatic. Gene expression levels of OPN were found to be significantly (p=0.0002) elevated for the metastatic group compared to the non-metastatic group. Hence, the human breast cancer cell lines - metastatic (MDA-MB-231 and SUM 149) and non-metastatic (BT-474 and T47D) from the American Type Culture Collection were cultured and their OPN expression at mRNA and protein levels determined by qRT-PCR and Western blotting were compared. Additionally the same cell lines were cultured in media enriched with an osteogenic cocktail containing 10mM β-glycerophosphate (Sigma, USA) and 50 mg/ml-1 ascorbic acid (Sigma, USA) for induction of microcalcifications.Next, several clones were generated using shRNA knockdown of OPN gene in MDA-MB-231 cells for further study. In vitro studies were conducted to assess the effects of OPN knockdown on the migration and invasion potential of MDA-MB-231 cells using transwell migration assays.
Results: The expression of OPN at both mRNA and protein levels are significantly higher for the metastatic cell lines when compared to non-metastatic cell lines. It can also be observed that OPN expression in the cells increases substantially with addition of exogenous phosphates in the form of osteogenic cocktail and thereby indicating that OPN possibly plays a crucial role in mediating formation of microcalcifications in these cells(P<0.001). Metastatic cell line MDA-MB-231 was employed as a model system for further investigation in this study. There is a consistent inhibition of formation of cellular microcalcifications due to the knockdown of gene responsible for OPN, suggesting that OPN gene is directly associated with the formation and regulation of hydroxyapatite formation in MDA-MB-231 breast cancer. Further, the above observation is strengthened by the similarity of the trend of variation in level of mRNA expression of OPN and cellular calcification content across the knockdown clones. OPN knockdown cell lines show reduced cell migration and invasion in the assays compared to the control MDA-MB-231 cells.
Conclusion: The knockdown of OPN gene not only reduced the formation of microcalcifications in the cells in response to osteogenic cocktail but also affected their migration and invasion characteristics. The observed dual roles of the OPN gene encourage us to probe further into the possible existence of a direct relationship between microcalcifications and ability to metastasize to distant organs mediated by common genetic factors in the future.

Abstract
Abstract
Background: An alarmingly large proportion of cancer-related deaths result from metastatic cancers. Development of quick, reliable and non-invasive or minimally invasive approaches to objectively assess the secondary tissues (potentially in vivo) will be instrumental in substantially reducing the cancer burden due to metastasis, which accounts for majority of cancer related mortality. In our study we report the utilization of Raman spectroscopy and chemometric techniques in identifying formation of pre-metastatic niche in lungs prior to observing morphological changes.
Methods: Six-week-old female athymic nu/nu mice (NCI, MD) were implanted with 2x106 cells of human breast cancer cell lines - MDA-MB-231 (n=3), and MCF-7 (n=3) in their fourth right mammary fat pad orthotopically. And control mice (n=3) without tumor cell implantation were also employed. The primary tumor size was monitored and the mice were sacrificed within 8-12 weeks of cell implantation when the primary tumors volume grew to 500-600 mm3. Control mice were also sacrificed in this timeframe. The freshly excised lungs of the mice were cleaned in PBS and utilized for obtaining Raman spectra (830 nm, thermoelectrically cooled CCD). Each tissue was collected from multiple points. Principal component analysis (PCA) and Partial least squares discriminant analysis (PLS-DA) were employed as discriminating algorithm. Following spectral acquisition, the tissues were fixed in 10% formalin, embedded in paraffin, and then HE staining, and Masson's trichrome staining for collagen. Collagen quantification of Masson's trichrome stained slides was achieved using MATLAB (Mathworks, MA). The Institutional Animal Care and Use Committee at Johns Hopkins University School of Medicine approved the protocol of the study.
Results: 900 Raman spectra each acquired from the lungs of the control mice and mice bearing MCF-7 and MDA-MB-231 tumor xenografts were assigned class labels - 'Control', 'MCL' and 'MDL' respectively for further analysis. Select principal components from those obtained by subjecting all the chosen 900 spectra to PCA clearly evident that the differences in the Raman spectra belonging to tissues being primed by derivatives of different primary cells are quite pronounced. The average correct rates of PLS-DA prediction of 90.1%, 97.7% and 78.4% were obtained for the spectra belonging to the classes - Control, MCL and MDL respectively. The HE images are negative for any signs of cancerous lesions. Masson's trichrome staining results show that the metastatic potential of the cell lines responsible for the primary tumor is positively correlated with the collagen density in the pre-metastatic niche, the MDL shows the highest collagen density (P<0.001). These differences clearly indicate the remodeling of extracellular matrix anticipating incoming tumor cells in response to primary tumor derived factors occurs very early in the metastatic cascade.
Conclusion: The current study introduces Raman spectroscopy in conjunction with chemometric techniques as are liable and minimally invasive tool for diagnosis of metastatic cancers significantly early in the metastatic cascade, and also opens a new route for early targeting of cancer metastasis and its associated burden.

Abstract
To estimate the potential risk of malignancy in endometrial polyps and to investigate the possible clinical risk factors. Clinical, sonographic, hysteroscopic and pathological data were reviewed of 337 women with pathologically confirmed endometrial polyps diagnosed in Qatar between 2000 and 2010. The polyps were benign in 95.6% of cases, pre-malignant in 2.3%, and malignant in 2.1 % of cases. Advanced age, menopausal status and vaginal bleeding were strongly associated with atypical hyperplasia and cancer. There appeared to be no association between the risk of malignancy and other clinical risk factors.
Conclusions: There is a small risk of malignancy in endometrial polyps, mainly in post-menopausal patients of advanced age with symptomatic vaginal bleeding. In these circumstances, endometrial polyps should be managed aggressively as potential cancer and removalfor histology is mandatory.

Abstract
Longitudinal studies of lactate MRSI and dynamic contrast-enhanced MRI were performed at 4.7 T in two prostate tumor models grown in rats, Dunning R3327-AT (AT) and Dunning R3327-H (H), to determine the potential of lactate and the perfusion/permeability parameter Ak(ep) as markers of tumor aggressiveness. Subcutaneous AT (n = 12) and H (n = 6) tumors were studied at different volumes between 100 and 2900 mm(3) (Groups 1-5). Lactate concentration was determined using selective multiple quantum coherence MRSI with the phantom substitution method. Tumor enhancement after the administration of gadolinium diethylenetriaminepenta-acetic acid was analyzed using the Brix-Hoffmann model and the Ak(ep) parameter was used as a measure of tumor perfusion/permeability. Lactate was not detected in the smallest AT tumors (Group 1; 100-270 mm(3) ). In larger AT tumors, the lactate concentration increased from 2.8 ± 1.0 mm (Group 2; 290-700 mm(3)) to 8.4 ± 2.9 mm (Group 3; 1000-1340 mm(3)) and 8.2 ± 2.2 mm (Group 4; 1380-1750 mm(3) ), and then decreased to 5.0 ± 1.7 mm (Group 5; 1900-2500 mm(3)), and was consistently higher in the tumor core than in the rim. Lactate was not detected in any of the H tumors. The mean tumor Ak(ep) values decreased with increasing volume in both tumor types, but were significantly higher in H tumors. In AT tumors, the Ak(ep) values were significantly higher in the rim than in the core. Histological hypoxic and necrotic fractions in AT tumors increased with volume from 0% in Group 1 to about 20% and 30%, respectively, in Group 5. Minimal amounts of hypoxia and necrosis were found in H tumors of all sizes. Thus, the presence of lactate and heterogeneous perfusion/permeability are signatures of aggressive, metabolically deprived tumors.
