Chromatographic analysis of the chemical composition and anticancer activities of Curcuma longa extract cultivated in Palestine. Open Life Sci 2023; 18:20220767. [PMID: 38027225 PMCID: PMC10668110 DOI: 10.1515/biol-2022-0767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 10/02/2023] [Accepted: 10/10/2023] [Indexed: 12/01/2023] Open
Abstract
Curcuma longa (turmeric) is a plant that has been extensively utilized in traditional medicine for centuries. Turmeric has a long history of use in both food and traditional medicine for the treatment of ailments such as diarrhea, cancer, flatulence, and dyspepsia. In Palestine, this plant was cultivated for the first time. The objective of this study was to characterize the extract of C. longa and assess its antimutagenic activity against a variety of cancer cells. Gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) methods were employed to identify the constituents of turmeric. The cytotoxic effects of C. longa were evaluated on cancer and normal cell lines using the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium assay. The results revealed the presence of 10 components in turmeric extract as identified by GC-MS. The major constituents comprising 78% of the total constituents were α-zingiberene (27.51%), tumeron (19.44%), β-sesquiphellandrene (19.40%), and aromatic-tumeron (11.63%). HPLC analysis successfully separated the main constituent, curcumin (1.78%), along with two other curcumin derivatives. The cytotoxicity results demonstrated potent anticancer activity of the C. longa extract against HeLa and LX2 cell lines, with IC50 values of 46.84 ± 2.12 and 29.77 ± 1 µg/mL, respectively. Furthermore, the plant extract at a concentration of 250 µg/mL exhibited over 95% inhibition against all tested cancer cell lines. These findings highlight the promising potential of turmeric as a natural source with powerful anticancer activities. Moreover, the extract may possess other biological activities such as antioxidant and antimicrobial properties, which could be explored in future studies.

Abstract
OBJECTIVE Sunlight and vitamin D intake are considered as essential elements for human health. Insufficient intake of this vitamin is one of the causes of various cancers and some other diseases. The aim of this study was to investigate the relation between bladder, prostate, cervical and ovarian cancers with solar ultraviolet exposure in Iran. In this ecological study, data from 30 provinces were studied and analyzed by correlation and linear regression tests in SPSS software version 22. Physical activity, gender, human development index, lung cancer and altitude were adjusted at population level. RESULTS The incidence of bladder cancer in both sexes was inversely related to ultraviolet radiation, but it was significant only in men. Unlike bladder cancer, the incidence of cervical cancer showed a positive relation with ultraviolet radiation. No relation was found between the incidence of prostate and ovarian cancers with ultraviolet radiation. Among the adjusting variables, the incidence of lung cancer (surrogate for smoking) in women had the highest coefficient in the linear regression model.

Abstract
Antiphospholipid antibodies are highly prevalent in autoimmune diseases and mainly associated with thromboembolic events, which is one of the major reasons for cancer-related mortality. Confirmed adult cancer patients were included (n = 40) with an equal number of age- and sex-matched healthy controls. The presence and concentration of anticardiolipin antibodies were investigated by the enzyme-linked immunosorbent assay using the venous blood samples. aCL antibodies were detected in 60.0% (n = 24) of the cancer patients compared to none in the healthy controls (p < 0.001). The serum concentration of aCL antibodies was significantly higher in cancer patients than controls (p < 0.001) and ranged from 89.0 U/mL to 133.0 U/mL among the aCL-positive patients. All the lung cancer patients (n = 6) were diagnosed with positive aCL, and a borderline significant association of aCL antibody positivity was observed in colon cancer patients (p = 0.051). About 72.7% of the advanced-stage cancer individuals and 81.8% of the cancer patients who underwent surgery were diagnosed with positive aCL antibodies. A significant association of aCL antibody positivity was observed with cancer patients comorbid with heart diseases (p = 0.005). The prevalence and serum levels of aCL antibodies were significantly higher in cancer patients compared to healthy controls. Cancer patients (i.e., lung, liver, and colon), at advanced-stage, comorbid with heart diseases, who underwent surgery, were more likely to be diagnosed with aCL antibodies.

Abstract
The severity and prevalence of cancer in modern time are a huge global health burden. Continuous efforts are being made toward the development of newer therapeutic candidates to treat and manage this ailment. The dihydropyrimidinone scaffold is one of the key nuclei that have been highly explored and investigated against cancer. It has the potential to combat the consequences of cancer by interacting with several biological targets. Tubulin polymerization inhibition is one such strategy to prevent the progression of cancer. In the presented work, we have synthesized a series of sixteen dihydropyrimidinone derivatives by following a rational drug design. The synthesized compounds have been characterized by 1H NMR and 13C NMR and were further evaluated for cytotoxic activity against breast cancer cell lines (MCF-7 and MDA-MB-231), lung cancer cell lines (A549), and colon cancer cell lines (HCT-116). Compounds 5D and 5P were found most potent and revealed a better cytotoxic activity compared with the standard drug colchicine. Furthermore, the tubulin polymerization inhibition assay revealed that compound 5D showed better inhibition than colchicines, whereas compound 5P revealed an almost equal inhibition to that of colchicine. Furthermore, to investigate the possible mode of action and binding patterns, compounds 5P and 5D were subjected to molecular docking against tubulin (Protein Data Bank ID: ISA0). The results showed that compounds revealed significant interactions and were well occupied inside the cavity of tubulin. The compounds 5D and 5P may serve as new leads in drug development against cancer.

An analysis of policy and funding priorities of global actors regarding noncommunicable disease in low- and middle-income countries. Global Health 2021; 17:68. [PMID: 34187499 PMCID: PMC8240078 DOI: 10.1186/s12992-021-00713-4] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 06/08/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Noncommunicable diseases (NCDs), including mental health, have become a major concern in low- and middle-income countries. Despite increased attention to them over the past decade, progress toward addressing NCDs has been slow. A lack of bold policy commitments has been suggested as one of the contributors to limited progress in NCD prevention and management. However, the policies of key global actors (bilateral, multilateral, and not-for-profit organisations) have been understudied. METHODS This study aimed to map the key global actors investing in action regarding NCDs and review their policies to examine the articulation of priorities regarding NCDs. Narrative synthesis of 70 documents and 31 policy papers was completed, and related to data collated from the Global Health Data Visualisation Tool. RESULTS In 2019 41% of development assistance for health committed to NCDs came from private philanthropies, while that for other global health priorities from this source was just 20%. Through a range of channels, bilateral donors were the other major source of NCD funding (contributing 41% of NCD funding). The UK and the US were the largest bilateral investors in NCDs, each contributing 8%. However, NCDs are still under-prioritised within bilateral portfolios - receiving just 0.48% of US funding and 1.66% of the UK. NGOs were the key channels of funding for NCDs, spending 48% of the funds from donors in 2019. The reviewed literature generally focused on NCD policies of WHO, with policies of multilateral and bilateral donors given limited attention. The analysis of policies indicated a limited prioritisation of NCDs in policy documents. NCDs are framed in the policies as a barrier to economic growth, poverty reduction, and health system sustainability. Bilateral donors prioritise prevention, while multilateral actors offer policy options for NCD prevention and care. Even where stated as a priority, however, funding allocations are not aligned. CONCLUSION The growing threat of NCDs and their drivers are increasingly recognised. However, global actors' policy priorities and funding allocations need to align better to address these NCD threats. Given the level of their investment and engagement, more research is needed into the role of private philanthropies and NGOs in this area.

Abstract
In India, population-based cancer registries (PBCRs) cover less than 15% of the urban and 1% of the rural population. Our study examines practices of registration in PBCRs in India to understand efforts to include rural populations in registries and efforts to measure social inequalities in cancer incidence. We selected a purposive sample of six PBCRs in Maharashtra, Kerala, Punjab and Mizoram and conducted semistructured interviews with staff to understand approaches and challenges to cancer registration, and the sociodemographic information collected by PBCRs. We also conducted a review of peer-reviewed literature utilizing data from PBCRs in India. Findings show that in a context of poor access to cancer diagnosis and treatment and weak death registration, PBCRs have developed additional approaches to cancer registration, including conducting village and home visits to interview cancer patients in rural areas. Challenges included PBCR funding and staff retention, abstraction of data in medical records, address verification and responding to cancer stigma and patient migration. Most PBCRs published estimates of cancer outcomes disaggregated by age, sex and geography. Data on education, marital status, mother tongue and religion were collected, but rarely reported. Two PBCRs collected information on income and occupation and none collected information on caste. Most peer-reviewed studies using PBCR data did not publish estimates of social inequalities in cancer outcomes. Results indicate that collecting and reporting sociodemographic data collected by PBCRs is feasible. Improved PBCR coverage and data will enable India's cancer prevention and control programs to be guided by data on cancer inequities.

Abstract
Globally, cancer is likely to be ranked as the leading cause of death among non-communicable diseases in the 21st century. In Ghana, estimates suggest that the disease is expected to increase continuously. The best way to address the increasing burden is through a comprehensive cancer control program. This paper presents an appraisal of the literature, reports and, studies that seek to highlight strategies for cancer control globally and in Ghana. In consideration of literature, a search of relevant databases (PubMed, Google Scholar, Cochrane Database of Systematic Reviews, Google, International organizations web pages, International reports, Ministry of Health of Ghana reports, and textbooks) was performed. A narrative review of the background information on this subject is provided to inform future research on cancer control. This review was conducted as part of a study to involve community pharmacists in cancer detection and prevention in Ghana.

Abstract
Background: In 2018, the global estimate of newly diagnosed breast cancer cases among women totaled 2.1 million. The economic and social burden that breast cancer places on societies has propelled research that analyzes the role of modifiable risk factors as the primary prevention methods. Healthy behavior changes, moderated alcohol intake, healthy body weight, and regular physical activity may decrease the risk of breast cancer among women. This review aimed to synthesize evidence on the cost-effectiveness of lifestyle-related interventions for the primary prevention of breast cancer in order to answer the question on whether implementing interventions focused on behavior changes are worth the value for money. Methods: A rapid review was performed using search terms developed by the research team. The articles were retrieved from MEDLINE and the Tufts Medical Center Cost-Effectiveness Analysis Registry, with an additional web search in Google and Google Scholar. Comparisons were performed on the cost-effectiveness ratio per quality-adjusted life-year between the interventions using a league table, and the likelihood of cost-effective interventions for breast cancer primary prevention was analyzed. Results: Six studies were selected. The median cost-effectiveness ratio (in 2018 USD) was $24,973, and 80% of the interventions had a ratio below the $50,000 threshold. The low-fat-diet program for postmenopausal women was cost-effective at a societal level, and the physical activity interventions, such as the Be Active Program in the UK, had the best cost saving results. A total of 11 of the 25 interventions ranked either as highly or very highly likely to be cost-effective for breast cancer primary preventions. Conclusion: Although the review had some limitations due to using only a few studies, it showed evidence that diet-related and physical-activity-related interventions for the primary prevention of breast cancer were cost-effective. Many of the cost-effective interventions aimed to reduce the risk of non-communicable diseases alongside breast cancer.

Abstract
Cancer is a leading cause of death in small island nations and is forecast to increase substantially over the coming years. Governments, regional agencies, and health services of these nations face daunting challenges, including small and fragile economies, unequal distribution of resources, weak or fragmented health services, small population sizes that make sustainable workforce and service development problematic, and the unavailability of specialised cancer services to large parts of the population. Action is required to prevent large human and economic costs relating to cancer. This final Series paper highlights the challenges and opportunities for small island nations, and identifies ways in which the international community can support efforts to improve cancer control in these settings. Our recommendations focus on funding and investment opportunities to strengthen cancer-related health systems to improve sharing of technical assistance for research, surveillance, workforce, and service development, and to support small island nations with policy changes to reduce the consumption of commodities (eg, tobacco and unhealthy food products) that increase cancer risk.

Zhang Y, Ye W, Yang C, Xu Z. Simultaneous quantitative detection of multiple tumor markers in microfluidic nanoliter-volume droplets. Talanta 2019; 205:120096.

Abstract
We developed a simultaneous detection method for multiple tumor markers (TMs) in microfluidic droplets based on a multiple fluorescence resonance energy transfer (FRET) system. In this system, graphene oxide (GO) was used as the single quencher, while the multi-color quantum dots (QDs) labeled on different aptamers were employed as energy donors. When the aptamers were adsorbed onto GO due to the π-π stacking interaction, QDs were drawn to the surface of GO and quenched by it. Once the TMs were introduced, the corresponding fluorescence of QDs was recovered obviously owing to the preferential interaction of aptamers with the TMs. Here, the multi-FRET system was encapsulated into nanoliter-volume droplets by a simple T-junction microfluidic chip. The targets could be detected rapidly as the generated droplets flew through the integrated on-line detection zone. Three tumor markers, carcinoembryonic antigen (CEA), prostate-specific antigen (PSA) and vascular endothelial growth factor (VEGF165) could be detected simultaneously in 33 nL-volume droplets, which is only 1/3000 of the volume of the sample consumed in the conventional fluorescence spectrophotometer. In addition, the signals corresponding to different TM targets in one nanoliter-volume droplet could be read out at the same time, and the signals could be output continuously owing to the uninterruptible generation of droplets. Even with a signal acquisition frequency of 55 droplets per minute, the multi-FRET biosensing system has linear ranges of 0.50-70 ng mL-1 for CEA, 0.25-70 ng mL-1 for PSA and 0.50-70 ng mL-1 for VEGF165. The detection limits of CEA, PSA and VEGF165 were calculated to be 0.15 ng mL-1, 0.035 ng mL-1 and 0.11 ng mL-1, respectively. The method was also validated by analyzing human serum sample dilutions. The proposed multi-FRET-based system has potential to become a powerful tool for rapid, low-cost and simultaneous detection of multiple tumor markers.

Wu TY, Lee J. Promoting Breast Cancer Awareness and Screening Practices for Early Detection in Low-Resource Settings. Eur J Breast Health 2018; 15:18-25. [PMID: 30816360 DOI: 10.5152/ejbh.2018.4305] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Accepted: 09/14/2018] [Indexed: 12/12/2022]
Abstract
Objective Breast cancer is the most common type of cancer among women in the Philippines. Philippines has one of the highest breast cancer mortality rate and the lowest mortality-to-incidence ratio in Asia. This study has three objectives: 1) explore Filipino women's knowledge, attitudes toward, and practices of breast cancer and cancer screening, 2) examine if an educational program increases women's intention to seek future breast cancer screening, and 3) examine associations between demographic variables and breast cancer screening practices. Materials and Methods A total of 944 women from two urban areas (Calasciao and Tacloban City) and one rural area (Sogood) of the Philippines participated in this cross-sectional study. Study participants attended an educational program and completed study questionnaires regarding demographics, knowledge about, and practices of breast self-exams, clinical breast exams and mammography as well as reported barriers toward future screening. Results The results showed a disparity between knowledge of routine breast cancer screening and actuals screening behaviors. Following breast health education and screening programs, participants reported greater intention to adhere to recommended breast cancer screening guidelines. The multivariate analyses showed that education level is a significant predictor for CBE and mammography uptake in current study. Conclusion This study has implications for breast cancer control among women in low-resources settings. Designing and implementing effective educational programs that increase women's awareness about breast cancer and promote screening uptake are important steps to reduce the burden affected by breast cancer among women in the Philippines and other South Asian low- to middle-income countries.

Abstract
A series of novel fusidic acid (FA) derivatives were synthesized and screened for their in vitro cytotoxicity against the Hela, U87, KBV and MKN45 cancer cell lines. Selected FA derivatives with anti-tumor activity were firstly identified including compound 4, which exhibited good anti-proliferative activity with IC50 values in the range of 1.26-3.57 μM. Further research revealed that compound 4 induced Hela cells to undergo apoptosis by increasing the ratio of the cells in the Sub-G0/G1 phase via decreasing the neo-synthesized proteins in a dose-dependent manner from 1 to 10 μM. Compound 4 also showed good in vivo anti-tumor activity against the xenograft tumor of Hela cells and had no apparent toxicity. This study highlights the advantage of introducing the medium-length amino-terminal groups at the 3-OH position of FA to enhance its anti-tumor activity and suggests that compound 4 provides a starting point for designing more potent derivatives in the future.

Abstract
A viral etiology of cancer was first demonstrated in 1911 by Peyton Rous who injected cell-free filtrate from a chicken sarcoma into healthy chickens and found it induced a tumour. Since the discovery over 50 years ago of the Epstein-Barr virus as the cause of Burkitt lymphoma, seven other human viruses or groups of viruses-hepatitis B virus, hepatitis C virus, human immunodeficiency virus type 1, some human papillomaviruses, human T-cell lymphotropic virus type 1, Kaposi sarcoma-associated herpesvirus and Merkel cell polyomavirus-have been linked to human cancer. Collectively, these eight viruses cause over 20 different types of cancer and contribute to 10-12% of all cancer, with a greater burden in low- and middle-income countries. For many viruses, immunosuppression greatly increases the risks of persistent infection, development of chronic sequelae and cancer. Although several viruses share similar routes of transmission (especially sexual activity, injection drug use and mother-to-child transmission), the predominant route of transmission varies across viruses, and for the same virus can vary by geographical location. In general, vulnerable populations at the greatest risk for viral infections and their associated diseases include people, especially children, living in low- to middle-income countries, men who have sex with men, people who use injection drugs and female sex workers.This article is part of the themed issue 'Human oncogenic viruses'.

Abstract
Cancers have been the leading cause of death worldwide and poor diet and physical inactivity are major risk factors in cancer-related deaths. Micronutrients such as vitamins and minerals appear to have preventive properties against cancer. One important mechanism by which dietary changes can exert preventive effects on cancer is via the modulation of micronutrient concentrations in target tissues. Many of these micronutrients are available in the form of dietary supplements, and the intake of these supplements is prevalent in various parts of the world. However, in most cases, it is not known which micronutrient (or combination of micronutrients) is best when it comes to lowering the risk of cancer. The present review illustrates the effect of vitamin D and ascorbic acid intake on preventing cancer.

Abstract
In an attempt to arrive at a more potent cytotoxic agent than the parent compound α-hederagenin (H), 24 α-hederagenin derivatives (5-8, 11-24, 27-28, 31-32, and 35-36) were synthesized in a concise and efficient strategy and screened for in vitro cytotoxicity against the human cancer cell lines MKN45 and KB. Among these compounds, the polyamine derivative 15 exhibited more potency than the parent compound with IC50 values in the range of 4.22 μM-8.05 μM. Compound 15 increased Bax/bcl-2 ratio that disrupted the mitochondrial potential and induced apoptosis. Therefore, the present studies highlight the importance of polyamine derivatives of α-hederagenin in the discovery and development of novel anticancer agents.

Abstract
Compared with traditional anti-tumor drugs, antimicrobial peptides as novel anti-tumor agents have prominent advantages of higher specificity and circumvention of multi-drug resistance. BP100 is a multifunctional membrane-active peptide with high antimicrobial activity. Taking BP100 as a lead peptide, we designed and synthesized a series of aliphatic chain-conjugated peptides through solid-phase synthesis. Biological evaluation revealed that these peptides exhibited better anti-cancer activity than BP100. Further investigations revealed that these peptides could disrupt the cell membrane and trigger the cytochrome C release into cytoplasm, which ultimately resulted in apoptosis. Meanwhile, these peptides also exhibited effective anti-tumor activity against multidrug resistant cells and had multidrug resistance-reversing effect. Additionally, conjugation of aliphatic acid to those peptides could enhance their stability in plasma. In conclusion, aliphatic acid-modified peptides might be promising anti-tumor agents for cancer therapy.

Abstract
The implication of inflammatory tissue damage in pathophysiology of human cancer as well as some metabolic disorders has been under intense investigation. Numerous studies have identified a series of critical signaling molecules involved in cellular responses to inflammatory stimuli. These include nuclear factor κB, peroxisome proliferator-activated receptor γ, nuclear factor erythroid 2 p45-related factor 2 and sterol regulatory element-binding protein 1. The proper regulation of these transcription factors mediating pro- and anti-inflammatory signaling hence provides an important strategy for the chemoprevention of inflammation-associated cancer. There is compelling evidence supporting that dietary supplementation with fish oil-derived ω-3 polyunsaturated fatty acids including docosahexaenoic acid (DHA) ameliorates symptomatic inflammation associated with cancer as well as other divergent human disorders. Acute or physiologic inflammation is an essential body's first line of defence to microbial infection and tissue injuries, but it must be properly completed by a process termed 'resolution'. Failure of resolution mechanisms can result in persistence of inflammation, leading to chronic inflammatory conditions and related malignancies. The phagocytic engulfment of apoptotic neutrophils and clearance of their potentially histotoxic contents by macrophages, called efferocytosis is an essential component in resolving inflammation. Of note, DHA is a precursor of endogenous proresolving lipid mediators which regulate the leukocyte trafficking and recruitment and thereby facilitate efferocytosis. Therefore, DHA and its metabolites may have a preventive potential in the management of human cancer which arises as a consequence of impaired resolution of inflammation as well as chronic inflammation.

Abstract
Over the past decades, extensive studies have addressed the therapeutic effects of omega-3 polyunsaturated fatty acids (omega-3 FAs) against different human diseases such as cardiovascular and neurodegenerative diseases, cancer, etc. A growing body of scientific research shows the pharmacokinetic information and safety of these natural occurring substances. Moreover, during recent years, a plethora of studies has demonstrated that omega-3 FAs possess therapeutic role against certain types of cancer. It is also known that omega-3 FAs can improve efficacy and tolerability of chemotherapy. Previous reports showed that suppression of nuclear factor-κB, activation of AMPK/SIRT1, modulation of cyclooxygenase (COX) activity, and up-regulation of novel anti-inflammatory lipid mediators such as protectins, maresins, and resolvins, are the main mechanisms of antineoplastic effect of omega-3 FAs. In this review, we have collected the available clinical data on the therapeutic role of omega-3 FAs against breast cancer, colorectal cancer, leukemia, gastric cancer, pancreatic cancer, esophageal cancer, prostate cancer, lung cancer, head and neck cancer, as well as cancer cachexia. We also discussed the chemistry, dietary source, and bioavailability of omega-3 FAs, and the potential molecular mechanisms of anticancer and adverse effects.

Abstract
Cardiovascular disease (CVD) has been the number one cause of death in the U.S. for 114 of the last 115 years. Lifestyle factors that promote CVD also appear to increase prostate cancer risk and those that reduce CVD risk also appear to reduce the risk of prostate cancer. The largest randomized trials utilizing dietary supplements or pharmacologic agents for prostate cancer prevention (Selenium and Vitamin E Cancer Prevention Trial [SELECT]) have also shed light on the problems and future solutions in this area. Dietary supplements that have not been found to be CVD protective, such as selenium and Vitamin E have not been found to be prostate protective. In addition, over exposure to specific anti-oxidants in nutritionally replete populations may be encouraging cancer growth. Future trials of dietary supplements to prevent prostate cancer could be problematic because by the time a definitive trial is initiated the participants will no longer be “deficient” in the nutrient being tested, which arguably occurred in the SELECT trial. It is also interesting that statins, aspirin, and/or metformin (S.A.M.) are 3 generic, low-cost, heart healthy agents derived from natural sources with separate mechanism of actions, which all appear to have the best benefit to risk ratio compared to any other agent available for prostate cancer prevention, especially aggressive disease, or as an ancillary agent (s) to conventional cancer treatment. It is time to focus on the forest over the trees and recommend proven CVD protective measures for men concerned about their risk of prostate cancer.

Abstract
Cancer is the second leading cause of death in developed countries and poor diet and physical inactivity are major risk factors in cancer-related deaths. Therefore, interventions to reduce levels of smoking, improve diet, and increase physical activity must become much higher priorities in the general population's health and health care systems. The consumption of fruit and vegetables exerts a preventive effect towards cancer and in recent years natural dietary agents have attracted great attention in the scientific community and among the general public. Foods, such as tomatoes, olive oil, broccoli, garlic, onions, berries, soy bean, honey, tea, aloe vera, grapes, rosemary, basil, chili peppers, carrots, pomegranate, and curcuma contain active components that can influence the initiation and the progression of carcinogenesis, acting on pathways implied in cell proliferation, apoptosis and metastasis. The present review illustrates the main foods and their active components, including their antioxidant, cytotoxic, and pro-apoptotic properties, with a particular focus on the evidence related to cancers of the digestive system.

Abstract
National cancer control plans are needed to stem the rapidly rising global cancer burden. Prevention and early detection are complementary but distinct strategies for cancer control. Some cancers are prevented through behavior and/or environmental modifications that reduce cancer risk, whereas other cancers are more amenable to treatment when they are successfully diagnosed at early stages. Prevention and early detection strategies should be prioritized on the basis of country-specific cancer demographics, modifiable risk factor distribution, and existing treatment resource availability. Following an individualized plan integrating prevention and early detection strategies, deficits can be targeted to strengthen national health systems for cancer control.

Abstract
Background Proven cost-effectiveness contrasted by low uptake of cancer screening (CS) calls for new methodologies promoting the service. Contemporary interventions in this regard relies primarily on strategies targeting general or specific groups with limited attention being paid to individualized approaches. This trial tests a novel package promoting CS utilization via continuous and tailored counseling delivered by primary caregivers. It aims at demonstrating that high risk individuals in the intervention arm will, compared to those in the delayed intervention condition, show increased use of CS service. Methods/Design The trial adopts a quasi-randomized controlled trial design and involves 2160 high risk individuals selected, via rapid and detailed risk assessments, from about 72,000 farmers aged 35+ in 36 administrative villages randomized into equal intervention and delayed intervention arms. The CS intervention package uses: a) village doctors and village clinics to deliver personalized and thus relatively sophisticated CS counseling; b) two-stage risk assessment models in identifying high risk individuals to focus the intervention on the most needed; c) standardized operation procedures to guide conduct of counseling; d) real-time effectiveness and quality monitoring to leverage continuous improvement; e) web-based electronic system to enable prioritizing complex determinants of CS uptake and tailoring counseling sessions to the changing needs of individual farmers. The intervention arm receives baseline and semiannual follow up evaluations plus CS counseling for 5 years; while the delayed intervention arm, only the same baseline and follow-up evaluations for the first 5 years and CS counseling starting from the 6th year if the intervention proved effective. Evaluation measures include: CS uptake by high risk farmers and changes in their knowledge, perceptions and self-efficacy about CS. Discussion Given the complexity and heterogeneity in the determinant system of individual CS service seeking behavior, personalized interventions may prove to be an effective strategy. The current trial distinguishes itself from previous ones in that it not only adopts a personalized strategy but also introduces a package of pragmatic solutions based on proven theories for tackling potential barriers and incorporating key success factors in a synergetic way toward low cost, effective and sustainable CS promotion.

Abstract
CONTEXT Tagetes patula Linn. (Asteraceae) (French Marigold) flowers are used by local practitioners for cancer treatment; however, it lacks scientific justification. OBJECTIVE Identification of bioactive compounds in T. patula flower for cytotoxic and growth inhibition in human cancer cell lines along with its antioxidant properties using chemical and cell based systems. MATERIALS AND METHODS The T. patula flower methanol extract, its seven fractions, and three phenolic compounds including methyl protocatechuate (1), patuletin (2), and patulitrin (3) were evaluated using sulforhodamine-B assay against HeLa, HT-144, NCI-H460, MCF-7, PC-3, and SF-268 human cancer cell lines. In parallel, antioxidant activity was evaluated using chemical (DPPH(·), deoxyribose, and lipid peroxidation assays) and cell-based chemiluminescence systems (human neutrophils and mice macrophages). RESULTS The methanol extract and ethyl acetate insoluble fraction exhibited cytotoxic and growth inhibitory effects against HeLa in which 2 exhibited highest cell growth inhibition (GI50: 0.6 ± 0.1 µg/ml) and cytotoxicity (LC50: 2.5 ± 0.1 µg/ml). It also scavenged LOO(·) (IC50: 6.5 ± 0.7 µg/ml) and [Formula: see text] (IC50: 27.5 ± 1.3 μg/ml) in chemical systems and human neutrophils, respectively. However, 1 preferably scavenged H2O2-Cl(-) (IC50: 0.5 ± 0.01 μg/ml) in mice macrophages. DISCUSSION AND CONCLUSION Compound 2 from T. patula flower exhibited both growth inhibitory and cytotoxic properties while 1 and 3 were only growth inhibitory against HeLa. 1-3 also displayed antioxidant properties implying its probable role in growth inhibition/cytotoxic action. The present study provides scientific evidence for the use of T. patula flower in cancer treatment by traditional healer.

Abstract
At present, a radical shift in cancer treatment is occurring in terms of predictive, preventive, and personalized medicine (PPPM). Individual patients will participate in more aspects of their healthcare. During the development of PPPM, many rapid, specific, and sensitive new methods for earlier detection of cancer will result in more efficient management of the patient and hence a better quality of life. Coordination of the various activities among different healthcare professionals in primary, secondary, and tertiary care requires well-defined competencies, implementation of training and educational programs, sharing of data, and harmonized guidelines. In this position paper, the current knowledge to understand cancer predisposition and risk factors, the cellular biology of cancer, predictive markers and treatment outcome, the improvement in technologies in screening and diagnosis, and provision of better drug development solutions are discussed in the context of a better implementation of personalized medicine. Recognition of the major risk factors for cancer initiation is the key for preventive strategies (EPMA J. 4(1):6, 2013). Of interest, cancer predisposing syndromes in particular the monogenic subtypes that lead to cancer progression are well defined and one should focus on implementation strategies to identify individuals at risk to allow preventive measures and early screening/diagnosis. Implementation of such measures is disturbed by improper use of the data, with breach of data protection as one of the risks to be heavily controlled. Population screening requires in depth cost-benefit analysis to justify healthcare costs, and the parameters screened should provide information that allow an actionable and deliverable solution, for better healthcare provision.

Abstract
INTRODUCTION Both baseline cardiorespiratory fitness and adiposity predict the risk of cancer mortality. However, the effects of changes in these two factors over time have not been evaluated thoroughly. The aim of this study was to examine the independent and joint associations of changes in cardiorespiratory fitness and body composition on cancer mortality. METHODS The cohort consisted of 13,930 men (initially cancer-free) with two or more medical examinations from 1974 to 2002. Cardiorespiratory fitness was assessed by a maximal treadmill exercise test, and body composition was expressed by body mass index (BMI) and percent body fat. Changes in cardiorespiratory fitness and body composition between the baseline and the last examination were classified into loss, stable, and gain groups. RESULTS There were 386 deaths from cancer during an average of 12.5 yr of follow-up. After adjusting for possible confounders and BMI, change hazard ratios (95% confidence intervals) of cancer mortality were 0.74 (0.57-0.96) for stable fitness and 0.74 (0.56-0.98) for fitness gain. Inverse dose-response relationships were observed between changes in maximal METs and cancer mortality (P for linear trend = 0.05). Neither BMI change nor percent body fat change was associated with cancer mortality after adjusting for possible confounders and maximal METs change. In the joint analyses, men who became less fit had a higher risk of cancer mortality (P for linear trend = 0.03) compared with those who became more fit, regardless of BMI change levels. CONCLUSIONS Being unfit or losing cardiorespiratory fitness over time was found to predict cancer mortality in men. Improving or maintaining adequate levels of cardiorespiratory fitness appears to be important for decreasing cancer mortality in men.

Abstract
Cancer control planning has become a core aspect of global health, as rising rates of noncommunicable diseases in low-resource settings have fittingly propelled it into the spotlight. Comprehensive strategies for cancer control are needed to effectively manage the disease burden. As the most common cancer among women and the most likely reason a woman will die from cancer globally, breast cancer management is a necessary aspect of any comprehensive cancer control plan. Major improvements in breast cancer outcomes in high-income countries have not yet been mirrored in low-resource settings, making it a targeted priority for global health planning. Resource-stratified guidelines provide a framework and vehicle for designing programs to promote early detection, diagnosis, and treatment using existing infrastructure and renewable resources. Strategies for evaluating the current state and projecting future burden is a central aspect of developing national strategies for improving breast cancer outcomes at the national and international levels.

Abstract
A Gram-positive, rod-shaped bacterium, designated as S-1, was isolated from a marine sediment sample collected from South China Sea. Phylogenetic analysis based on 16S rRNA gene sequence showed that S-1 belongs to the genus Brevibacillus. A novel cytotoxic peptide was isolated from the fermentation broth of the marine-derived bacterium Brevibacillus sp. S-1, using ion-exchange chromatography and reverse-phase HPLC chromatography. The molecular weight of this peptide was determined as 1570 Da by MALDI-TOF mass spectrometry, and its structure was proposed as a cyclic peptide elucidated by MALDI-TOF/TOF mass spectrometry and de novo sequencing. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay showed that this peptide exhibited cytotoxicity against BEL-7402 human hepatocellular carcinoma cells, RKO human colon carcinoma cells, A549 human lung carcinoma cells, U251 human glioma cells and MCF-7 human breast carcinoma cells. Additionally, SBP exhibited low cytotoxicity against HFL1 human normal fibroblast lung cells. The result suggested that the cytotoxic effect of the peptide is specific to tumor cells.

Abstract
This work shows, for the first time, the encapsulation of a highly relevant protein in the biomedical field into virus-like particles (VLPs). A bacterial CYP variant was effectively encapsulated in VLPs constituted of coat protein from cowpea chlorotic mottle virus (CCMV). The catalytic VLPs are able to transform the chemotherapeutic pro-drug, tamoxifen, and the emerging pro-drug resveratrol. The chemical nature of the products was identified, confirming similar active products than those obtained with human CYP. The enzymatic VLPs remain stable after the catalytic reaction. The potential use of these biocatalytic nanoparticles as targeted CYP carriers for the activation of chemotherapy drugs is discussed.

Abstract
The association between the rs7003908 (T>G) polymorphism in the XRCC7 gene and the risk of cancers had been widely studied; however, the results were inconsistent. The objective of the current study was to investigate the association between the rs7003908 polymorphism in the XRCC7 gene and the risk of cancers by meta-analysis. We searched PubMed, EMbase, CNKI and Wanfang databases; the last search was performed on January 10th, 2014. Statistical analysis was performed using the Revman4.2 and STATA10.0 softwares. A total of 3,684 cancer cases and 5,232 controls from 11 case-control studies were included for data analysis. In the dominant model analysis, the results suggested a lack of association between the polymorphism and the risk of cancers: OR 1.01, 95% CI 0.83-1.16, P = 0.70. In the subgroup analysis by ethnicity, no significant association was found either for Asians or Caucasians. In the subgroup analysis by cancer types, significant association was found for prostate cancer, but not for bladder cancer, breast cancer and glioma. In summary, the current meta-analysis confirmed that the rs7003908 polymorphism in the XRCC7 gene might be a risk factor for prostate cancer. In the future, more studies are needed to validate these results.

Abstract
PROBLEM Guatemala is experiencing an increasing burden of cancer but lacks capacity for cancer prevention, control and research. APPROACH In partnership with a medical school in the United States of America, a multidisciplinary Cancer Control Research Training Institute was developed at the Instituto de Cancerología (INCAN) in Guatemala City. This institute provided a year-long training programme for clinicians that focused on research methods in population health and sociocultural anthropology. The programme included didactic experiences in Guatemala and the United States as well as applied training in which participants developed research protocols responsive to Guatemala's cancer needs. LOCAL SETTING Although INCAN is the point of referral and service for Guatemala's cancer patients, the institute's administration is also interested in increasing cancer research - with a focus on population health. INCAN is thus a resource for capacity building within the context of cancer prevention and control. RELEVANT CHANGES Trainees increased their self-efficacy for the design and conduct of research. Value-added benefits included establishment of an annual cancer seminar and workshops in cancer pathology and qualitative analysis. INCAN has recently incorporated some of the programme's components into its residency training and established a research department. LESSONS LEARNT A training programme for clinicians can build cancer research capacity in low- and middle-income countries. Training in population-based research methods will enable countries such as Guatemala to gather country-specific data. Once collected, such data can be used to assess the burden of cancer-related disease, guide policy for reducing it and identify priority areas for cancer prevention and treatment.

Abstract
A new antitumor and antioxidant peptide (H3) was isolated from Arca subcrenata Lischke using ion exchange and hydrophobic column chromatography. The purity of H3 was over 99.3% in reversed phase-high performance liquid chromatography (RP-HPLC) and the molecular weight was determined to be 20,491.0 Da by electrospray-ionization mass spectrometry (ESI-MS/MS). The isoelectric point of H3 was measured to be 6.65 by isoelectric focusing-polyacrylamide gel electrophoresis. Partial amino acid sequence of this peptide was determined as ISMEDVEESRKNGMHSIDVNHDGKHRAYWADNTYLM-KCMDLPYDVLDTGGKDRSSDKNTDLVDLFELDMVPDRKNNECMNMIMDVIDTN-TAARPYYCSLDVNHDGAGLSMEDVEEDK via MALDI-TOF/TOF-MS and de novo sequencing. The in vitro antitumor activity of H3 was evaluated by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. The result indicated that H3 exhibited significant antiproliferative activity against HeLa, HepG2 and HT-29 cell lines with IC50 values of 10.8, 10.1 and 10.5 μg/mL. The scavenging percentage of H3 at 8 mg/mL to 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl radicals were 56.8% and 47.5%, respectively.

Abstract
BACKGROUND Nearly 13 million new cancer cases and 7.6 million cancer deaths occur worldwide each year; 63% of cancer deaths occur in low- and middle-income countries. A substantial proportion of all cancers are attributable to carcinogenic exposures in the environment and the workplace. OBJECTIVE We aimed to develop an evidence-based global vision and strategy for the primary prevention of environmental and occupational cancer. METHODS We identified relevant studies through PubMed by using combinations of the search terms "environmental," "occupational," "exposure," "cancer," "primary prevention," and "interventions." To supplement the literature review, we convened an international conference titled "Environmental and Occupational Determinants of Cancer: Interventions for Primary Prevention" under the auspices of the World Health Organization, in Asturias, Spain, on 17-18 March 2011. DISCUSSION Many cancers of environmental and occupational origin could be prevented. Prevention is most effectively achieved through primary prevention policies that reduce or eliminate involuntary exposures to proven and probable carcinogens. Such strategies can be implemented in a straightforward and cost-effective way based on current knowledge, and they have the added benefit of synergistically reducing risks for other noncommunicable diseases by reducing exposures to shared risk factors. CONCLUSIONS Opportunities exist to revitalize comprehensive global cancer control policies by incorporating primary interventions against environmental and occupational carcinogens.
