AIM: To study the pattern of presentation and to highlight the common causes of primary benign orbital lesions.of Jinnah Postgraduate Medical Centre Karachi from July 1997 to August 2001 and then from September 2001 to date (Continued) at the Department of Ophthalmology of Chandka Medical College & Hospital Larkana. Only patients with primary benign orbital lesions were included in this study. All the patients were admitted in eye ward from the out patients department. The diagnosis of the disease was based on the presentation, clinical examination, investigations and histopathology of excised mass. A total of 68 patients were included in this study. The age range was from 2 months to 60 years. Out of 68, 27 (39.7%) patients were male and 41 (60.3%) were female. The left orbit was involved in 35 (51.5%) and right orbit was involved in 33 (48.5%).revealed that superficial capillary hemangiomas of the eye lid were the most common lesion 26 (38.2%) followed by deep orbital cavernous hemangiomas 5 (7.4%), lymphangiomas 5 (7.4%), orbital varices 4 (5.9%), gliomas 7 (10.3%), meningiomas 5 (7.4%), neurofibromas 5 (7.4%), neurofibromatosis 4 (5.9%), schwannomas 2 (2.9%), and pleomorphic adenoma (benign mixed cell tumor) of lacrimal gland 5 (7.4%) cases.treatment can prevent the patient from visual and life threatening complications.

Objective: To explore antioxidant potential, anti-cancer activity, and phytochemicals of Commelina benghalensis L. Methods: The roots of Commelina benghalensis were extracted in different solvents (methanol, ethanol, benzene, chloroform, n-hexane) with a range of polarity. Antioxidant activity was evaluated by reducing power assay, DPPH radical scavenging activity and phosphomolybdenum method, cytotoxicity by MTT assay, apoptotic and cell cycle analysis by flow cytometry, migratory and invasive potential by wound scratch assay and invasion assay, respectively, functional groups analysis by FT-IR spectroscopy and phytochemicals by aluminum chloride colorimetric and Folin-Ciocalteu methods. Results: The extracts showed worthy antioxidant potential. The chloroform extract demonstrated the most significant cytotoxic effect on MDA-MB-231 (breast cancer) cell line, induced apoptosis and reduced migratory and invasive potential of MDA-MB-231 cells. Methanol and ethanol extracts presented good yield of total phenolic and total flavonoid contents. The FTIR spectroscopic studies revealed different characteristic peak values with various functional compounds such as alkenes, alkanes, aliphatic amines, aromatics, alkyl halides, carboxylic acid, alcohols, ester, aldehydes and ketones. Conclusions: The results demonstrate the potential use of Commelina benghalensis as a good antioxidant with significant anti-cancer effect.

Cancer is a frightful disease and represents one of the biggest health-care issues for the human race and demands a proactive strategy for cure. Plants are reservoirs for novel chemical entities and provide a promising line for research on cancer. Hitherto, being effective, chemotherapy is accompanied by certain unbearable side effects. Nevertheless, plants and plant derived products is a revolutionizing field as these are Simple, safer, eco-friendly, low-cost, fast, and less toxic as compared with conventional treatment methods. Phytochemicals are selective in their functions and acts specifically on tumor cells without affecting normal cells. Carcinogenesis is complex phenomena that involves many signaling cascades. Phytochemicals are considered suitable candidates for anticancer drug development due to their pleiotropic actions on target events with multiple manners. The research is in progress for developing potential candidates (those can block or slow down the growth of cancer cells without any side effects) from these phytochemicals. Many phytochemicals and their derived analogs have been identified as potential candidates for anticancer therapy. Effort has been made through this comprehensive review to highlight the recent developments and milestones achieved in cancer therapies using phytomolecules with their mechanism of action on nuclear and cellular factors. Furthermore, drugs for cancer treatment and their limitations have also been discussed.

Breast cancer is a frightful disease and serious concern in women around the world causing significant health care burden in both developed and developing countries. Extensive research work has shown that breast cancer provides strong resistance to chemical agents, UV radiation, and hormonal treatments. It is generally accepted that cell genetics is not the only main reason for breast cancer and genetic risk factors, for example, mutations in BRCA1 and BRCA2 genes constitute 5%-10% of all breast cancer rates. Other related factors include age, gender, race, ethnicity, weight, reproductive factors, exo- and endogenous hormonal exposures, oral contraceptives use, ultraviolet radiation, diet, and night work (circadian disruption). Many studies have revealed that dietary isoflavones regulate breast cancer occurrence, recurrence and prognosis. Dietary isoflavones have long been part of Asian population diet and there is a significant increase as compared to dietary isoflavones intake among other populations. Dietary isoflavones are natural phytoestrogens having both estrogenic and anti-estrogenic potentials on breast cancer cells in culture, animal models and in experimental trials. This literature survey provides a comprehensive overview on the tumor preventive and tumor promoting potentials of dietary isoflavones on breast cancer. In addition, this paper provides a literature review of dietary isoflavones and their effects on up-regulation and down-regulation of different signaling pathways, genes and proteins. Finally, future perspectives of dietary isoflavones and breast cancer researchers are also critically discussed, which will provide a deeper insight regarding the inner molecular mechanisms of action.

The National Cancer Institute had projected breast cancer (BC) as one of the topmost prevalent malignancies around the globe. In many cases, BC becomes resistant to chemotherapy, radiation and hormonal therapies. Traditional BC therapies are associated with adverse side effects, drug resistance and recurrence. Extensive research work has shown that these dietary phytochemicals (DPs) may exert therapeutic effects by regulating the miRNA expression. A large number of DPs have been researched as miRNA regulatory agents against BC and some other DPs have not yet been tested against BC. We have discussed the effects of curcumin, diallyl disulphide, 3,3′ diindolylmethane, ellagic acid, genistein, indole-3-carbinol, quercetin, resveratrol, and sulforaphane on regulation of expression of BC miRNAs in a wide range of in vitro and in vivo models. We have also shown some of the possible DPs (Oleanolic acid, capsaicin, benzyl isothiocyanate, epigallocatechin gallate, phenethyl isothiocyanate and ursolic acid) that have shown miRNA regulatory activities and have not yet been tested against BC miRNAs. Finally, current limitations, challenges, future perspectives of DPs and BC research are also critically discussed.
