    Cancer starts when cells in a part of the body start to grow out of control. In fact cells become cancer cells because of DNA damage. A DNA walk of a genome represents how the frequency of each nucleotide of a pairing nucleotide couple changes locally. In this research in order to study the cancer genes, DNA walk plots of genomes of patients with lung cancer were generated using a program written in MATLAB language. The data so obtained was checked for fractal property by computing the fractal dimension using a program written in MATLAB. Also, the correlation of damaged DNA was studied using the Hurst exponent measure. We have found that the damaged DNA sequences are exhibiting higher degree of fractality and less correlation compared with normal DNA sequences. So we confirmed this method can be used for early detection of lung cancer. The method introduced in this research not only is useful for diagnosis of lung cancer but also can be applied for detection and growth analysis of different types of cancers.

    Human pluripotent stem cells (hPSCs) derived from either blastocyst stage embryos (hESCs) or reprogrammed somatic cells (iPSCs) can provide an abundant source of human neuronal lineages that were previously sourced from human cadavers, abortuses, and discarded surgical waste. In addition to the well-known potential therapeutic application of these cells in regenerative medicine, these are also various promising nontherapeutic applications in toxicological and pharmacological screening of neuroactive compounds, as well as for in vitro modeling of neurodegenerative and neurodevelopmental disorders. Compared to alternative research models based on laboratory animals and immortalized cancer-derived human neural cell lines, neuronal cells differentiated from hPSCs possess the advantages of species specificity together with genetic and physiological normality, which could more closely recapitulate in vivo conditions within the human central nervous system. This review critically examines the various potential nontherapeutic applications of hPSC-derived neuronal lineages and gives a brief overview of differentiation protocols utilized to generate these cells from hESCs and iPSCs.

    BACKGROUND: Breast cancer is the leading cause of mortality among women worldwide. However, female patients often feel reluctant and embarrassed about meeting physicians in person to discuss their intimate body parts, and prefer to use social media for such interactions. Indeed, the number of patients and physicians interacting and seeking information related to breast cancer on social media has been growing. However, a physician may behave inappropriately on social media by sharing a patient's personal medical data excessively with colleagues or the public. Such an act would reduce the physician's trustworthiness from the patient's perspective. The multifaceted trust model is currently most commonly used for investigating social media interactions, which facilitates its enhanced adoption in the context of breast self-examination. The characteristics of the multifaceted trust model go beyond being personalized, context-dependent, and transitive. This model is more user-centric, which allows any user to evaluate the interaction process. Thus, in this study, we explored and evaluated use of the multifaceted trust model for breast self-examination as a more suitable trust model for patient-physician social media interactions in breast cancer screening.

    OBJECTIVE: The objectives of this study were: (1) to identify the trustworthiness indicators that are suitable for a breast self-examination system, (2) design and propose a breast self-examination system, and (3) evaluate the multifaceted trustworthiness interaction between patients and physicians.

    METHODS: We used a qualitative study design based on open-ended interviews with 32 participants (16 outpatients and 16 physicians). The interview started with an introduction to the research objective and an explanation of the steps on how to use the proposed breast self-examination system. The breast self-examination system was then evaluated by asking the patient to rate their trustworthiness with the physician after the consultation. The evaluation was also based on monitoring the activity in the chat room (interactions between physicians and patients) during daily meetings, weekly meetings, and the articles posted by the physician in the forum.

    RESULTS: Based on the interview sessions with 16 physicians and 16 patients on using the breast self-examination system, honesty had a strong positive correlation (r=0.91) with trustworthiness, followed by credibility (r=0.85), confidence (r=0.79), and faith (r=0.79). In addition, belief (r=0.75), competency (r=0.73), and reliability (r=0.73) were strongly correlated with trustworthiness, with the lowest correlation found for reputation (r=0.72). The correlation among trustworthiness indicators was significant (P

    In Malaysia, breast cancer is the commonest cancer among women indicating that early diagnosis and screening practice is important to increase the survival rate. Breast self-examination (BSE), clinical breast examination (CBE) and mammography are the main screening practices for breast cancer. Knowledge and awareness of breast cancer can play an important role in aiding early detection of breast cancer. Little is known about the knowledge of breast cancer and screening practices among the non-academic staff in IIUM, Kuantan. As such this study aims to determine the knowledge and screening practices of breast cancer amongst the non-academic staff at the International Islamic University Malaysia (IIUM), Kuantan Campus. A cross-sectional study was conducted on 100 nonacademic staff from ten different departments in IIUM, Kuantan from March to April 2017. Data were collected using a self-administered questionnaire on knowledge of breast cancer and screening practices. The relationship between socio-demographic characteristics and knowledge of breast cancer and breast cancer screening practices were carried out using chi-square. No significance difference was found between knowledge of breast cancer and socio-demographic factors. However significant relationships were found between the age of respondents and BSE as well as the level of education of respondents and CBE. Most non-academic staff possessed an average level of knowledge on breast cancer and screening practices due to possibly ease of access to information. Low performance of breast screening practices was indicated possibly due to lack of awareness, misconception of the need and benefits derived from such screening practices.

    Moringa oleifera is a miracle plant with many nutritional and medicinal properties. Chemopreventive values of the combined mixture of moringa leaves and seed residue (MOLSr) at different ratios (M1S9, M1S1 and M9S1) were investigated. MOLSr extracts were subjected to phytochemical screening, antioxidant assays, metabolite profiling and cytotoxic activity on the primary mammary epithelial cells (PMECs), non-malignant Chang's liver cells and various human cancer cell lines (including breast, cervical, colon and liver cancer cell lines). The MOLSr ratio with the most potent cytotoxic activity was used in xenograft mice injected with MDA-MB-231 cells for in vivo tumorigenicity study as well as further protein and gene expression studies. M1S9, specifically composed of saponin and amino acid, retained the lowest antioxidant activity but the highest glucosinolate content as compared to other ratios. Cell viability decreased significantly in MCF-7 breast cancer cells and PMECs after treatment with M1S9. Solid tumor from MDA-MB-231 xenograft mice was inhibited by up to 64.5% at third week after treatment with high-dose M1S9. High-dose M1S9 significantly decreased the expression of calcineurin (CaN) and vascular endothelial cell growth factor (VEGF) proteins as well as the secreted frizzled-related protein 1 (SFRP1) and solute carrier family 39 member 6 (SLC39A6) genes. This study provides new scientific evidence for the chemoprevention potential of MOLSr extracts in a breast cancer model; however, the precise mechanism warrants further investigation.

    INTRODUCTION: Brassica oleracea var acephala was studied for preliminary phytochemical screening. The results showed that the ethanolic crude extract of the leaf contain high phytochemical activity hence B.oleracea var acephala is rich in flavonoids, phenolic compounds, carbohydrates and phytosterols.

    MATERIALS AND METHODS: The ethanolic extract was used to synthesise copper nanoparticles. The copper nanoparticles were successfully synthesised from copper sulphate solution which was identified by the colour change from dark green colour of the extract. Thus the B.oleracea var acephala is a good source to synthesis copper nanoparticles. The synthesised copper nanoparticles were characterised using Scanning Electron Microscope (SEM) analysis. The SEM image displayed the high-density nanoparticles synthesised by leaf extracts and that the nanoparticles were crystals in shape.

    RESULTS: The copper nanoparticles (CNP) bind to the leaf extract. B.oleracea var acephala also has shown the antimicrobial and antioxidant activity. A comparative study was done between ethanolic its crude extract and nanoparticles. Both extracts exhibited zone of inhibition and better antioxidant potential but the CuNPs shows major zone of inhibition and showed more antioxidant activity. Anticancer activity of B.oleracea var acephala against Cervical HeLa cell line was confirmed using ethanolic crude extract and CNP. The results showed that HeLa cells proliferation was inhibited with increasing concentration of ethanolic crude extract and copper nanoparticles. From the results, it was seen that percentage viability of the cancer cells decreased with increased concentration of the samples whereas cytotoxicity against HeLa cell lines increased with the increased concentration of the samples.

    CONCLUSION: Thus B.oleracea var acephala possesses anticancer activity against HeLa cell lines.

    Breast cancer is the most common cancer in women world-wide. Incidence rates in low- and middle-income countries (LMICs) are lower than in high income countries; however, the rates are increasing very rapidly in LMICs due to social changes that increase the risk of breast cancer. Breast cancer mortality rates in LMICs remain high due to late presentation and inadequate access to optimal care. Breast Surgery International brought together a group of breast surgeons from different parts of the world to address strategies for improving outcomes in breast cancer for LMICs at a symposium during International Surgical Week in Helsinki, Finland in August 2013. A key strategy for early detection is public health education and breast awareness. Sociocultural barriers to early detection and treatment need to be addressed. Optimal management of breast cancer requires a multidisciplinary team. Surgical treatment is often the only modality of treatment available in low-resource settings where modified radical mastectomy is the most common operation performed. Chemotherapy and radiotherapy require more resources. Endocrine therapy is available but requires accurate assessment of estrogen receptors status. Targeted therapy with trastuzumab is generally unavailable due to cost. The Breast Health Global Initiative guidelines for the early detection and appropriate treatment of breast cancer in LMICs have been specifically designed to improve breast cancer outcomes in these regions. Closing the cancer divide between rich and poor countries is a moral imperative and there is an urgent need to prevent breast cancer deaths with early detection and optimal access to treatment.

    Acute lymphoblastic leukemia (ALL) is the most common
    childhood leukaemia. It is a malignant neoplasm caused by the proliferation of
    poorly differentiated precursors of the lymphoid cells. It is relatively
    uncommon in adult. In adult ALL, central nervous system (CNS) involvement
    is associated with poor prognosis. The incidence of CNS involvement has
    been reported between 7% and 15 %. We report a case of optic nerve
    infiltration in ALL in a 49 years old gentleman. He was diagnosed with
    precursor-B ALL. He was treated with chemotherapy and CNS prophylactic
    regime. He presented with sudden left eye loss of vision for one-day duration
    with history of right eye inferior visual field loss for the past three months. His
    visual acuity was no perception to light on the left eye and 6/9 on the right
    eye. There was marked left relative afferent pupillary defect. The right eye
    showed decreased in optic nerve function with inferior visual field defect.
    Anterior segment examination was unremarkable in both eyes. Left optic disc
    appeared normal but the right optic disc was pale. Blood investigation
    showed no sign of infection or haemoconcentration. Cerebral spinal fluids
    examination revealed abundant of white cells and blast cells. Magnetic
    resonant imaging showed bilateral optic nerve enhancement suggesting of
    bilateral optic nerves infiltration. He was started on a new regime of
    chemotherapy followed by cranial radiotherapy. Unfortunately, he succumbed
    to death due to septicaemia. There are variations in clinical presentation of
    optic nerve infiltration in leukaemic patients. Normal appearance of optic disc
    may not exclude the possibility of infiltration by malignancy. Assessment of
    the optic nerve function and imaging is helpful for the detection of leukaemic
    infiltration. Early detection of optic nerve infiltration is important for initiation or
    change of therapy to prevent mortality.

    Introduction: As cervical cancer is the third most common cancer among women and ten percent of cervical cancer incidence among those 65 years and above, Pap smear is still relevant to be performed among older women. The aim of this study was to determine the determinants of Pap smear screening among older women in an urban setting.
    Methods: This cross-sectional study was conducted among 515 women aged 50 and above in two urban health centres in Gombak, Selangor. The sampling technique conducted was random systematic sampling. The indepen-dent variables were age, marital status, employment status, gynaecological history (family history of cervical cancer, menopause, hysterectomy), obstetric history (number of live births, ever had contraception), presence of chronic diseases (hypertension, Diabetes Mellitus, heart disease). Results: Only 202 (39.2%) out of 515 undergone Pap smear screening. An estimated 80.7% of them had their last Pap smear a year ago. The mean age of the respondents was 58.83± 7.05 years old and 77.3% had one and more comorbidities. The respondents preferred health care person-nel as the source for the pap smear information compared to reading materials and internet.

    INTRODUCTION: Australia has recently implemented major changes in cervical cancer prevention policies including introduction of primary human papillomavirus (HPV) screening starting at age 25, and replacement of the quadrivalent HPV vaccine with the nonavalent vaccine in the national school-based program. We assessed the feasibility and utility of conducting HPV testing in residual clinical specimens submitted for routine Chlamydia trachomatis screening, as a means of tracking HPV vaccine program impact among young sexually active women.

    METHODS: De-identified residual specimens from women aged 16-24 years submitted for chlamydia testing were collected from three pathology laboratories in Victoria and New South Wales. Limited demographic information, and chlamydia test results were also collected. Patient identifiers were sent directly from the laboratories to the National HPV Vaccination Program Register, to obtain HPV vaccination histories. Samples underwent HPV genotyping using Seegene Anyplex II HPV 28 assay.

    RESULTS: Between April and July 2018, 362 residual samples were collected, the majority (60.2%) of which were cervical swabs. Demographic data and vaccination histories were received for 357 (98.6%) women (mean age 21.8, SD 2.0). Overall, 65.6% of women were fully vaccinated, 9.8% partially, and 24.7% unvaccinated. The majority (86.0%) resided in a major city, 35.9% were classified in the upper quintile of socioeconomic advantage and chlamydia positivity was 7.8%.The prevalence of quadrivalent vaccine-targeted types (HPV6/11/16/18) was 2.8% (1.5-5.1%) overall with no differences by vaccination status (p = 0.729). The prevalence of additional nonavalent vaccine-targeted types (HPV31/33/45/52/58) was 19.3% (15.6-23.8%). One or more oncogenic HPV types were detected in 46.8% (95% CI 41.6-52.0%) of women.

    CONCLUSIONS: HPV testing of residual chlamydia specimens provides a simple, feasible method for monitoring circulating genotypes. Applied on a larger scale this method can be utilised to obtain a timely assessment of nonavalent vaccine impact among young women not yet eligible for cervical screening.

    Pap smear screening is proven to be an effective tool for the early detection of cervical cancer. Public Health Laboratory of the Ministry of Health Malaysia (MOH) reported that Pontian Health District achieved only 69.4% out of the 4,112 targeted Pap smear screening performed in 2014. Pontian District Health Office conducted a Quality Assurance (QA) project, aiming to increase the percentage of Pap smear screening uptake among women in Pontian district to 100%.
    A cross-sectional study using questionnaires was conducted in January 2015 involving 256 women to measure their knowledge, attitude, and practice towards Pap smear screening. The results showed 93.8% of respondents have a good knowledge of Pap smear. However, only 72% agreed to do Pap smear screening while 28% refused to do the screening. The 72 women declined the Pap smear screening for various reasons, such as time constraint (27%) feeling shy (27%), perceived the procedure as painful (23%), afraid to know the result (19%) and perceived the screening as unimportant (4%). The results also revealed only 44% of the respondents received information about Pap smear screening from health staff.
    Several strategies were identified to overcome the reasons; the expansion of Pap smear screening to the workplace and residences overcome time constraint issue, an innovative tool known as “Sisih Malu” to combat the shyness feeling of doing Pap smear screening, while “Celik Servik” demonstrates the procedure as simple and painless. Active promotion of Pap smear screening was also conducted by the clinics’ staff who emphasised on cervical cancer early detection, which is more treatable at an early stage. These improvement strategies were conducted from February until December 2015.
    Post-intervention saw Pap smear screening in Pontian district increased to 4,936 (118.9%), exceeding the 4,152 target set for 2015 and increased 130.5% in 2016. Another survey among 99 women in January 2016 showed that a 100% willingness to undergo a Pap smear screening

    This work explores Electrochemical Impedance Spectroscopy (EIS) detection for a highly-sensitive quantification of prostate-specific antigen (PSA) in Faradaic (f-EIS) and non-Faradaic modes (nf-EIS). Immobilization of monoclonal antibody specific to PSA (anti-PSA) was performed using 1-ethyl-3-dimethylaminopropylcarbodiimide hydrochloride and N-hydroxysuccinimide crosslinking agents in order to conjugate carboxylic (-COOH) terminated group of 16-Mercaptoundecanoic acid with amine (-NH3+) on anti-PSA epitope. This approach offers simple and efficient approach to form a strong, covalently bound thiol-gold (SAu) for a reliable SAM layer formation. Studies on the topographic of pristine Au-IDE surface were performed by Scanning Electron Microscopy and Energy Dispersive X-ray Spectroscopy techniques, meanwhile a 3-dimensional optical surface profiler, Atomic Force Microscopy and X-ray Photoelectron Spectroscopy techniques were used to validate the successful functionalization steps on the sensor transducer surface. Detection of PSA in f-EIS mode was carried out by measuring the response in charge transfer resistance (Rct) and impedance change (Z), meanwhile in nf-EIS mode, the changes in device capacitance was monitored. In f-EIS mode, the sensor reveals a logarithmic detection of PSA in a range of 100 ng/ml down to 0.01 ng/ml in Phosphate Buffered Saline with a recorded sensitivity of 2.412 kΩ/log10 ([PSA] ng/ml) and the limit of detection (LOD) down to 0.01 ng/ml. The nf-EIS detection mode yields a logarithmic detection range of 5000 ng/ml down to 0.5 ng/ml, with a sensitivity of 8.570 nF/log10 ([PSA] ng/ml) and an LOD of 0.5 ng/ml. The developed bio-assay yields great device stability, specificity to PSA and repeatability of detection that would pave its way for the future development into portable lab-on-chip bio-sensing system.

    Introduction: Cervical cancer remains the second commonest female malignancy worldwide and the seventh among Malaysians. Globally in 2012, an estimated 528 000 women developed cervical cancer and almost 266 000 died from this disease. Of all cervical cancers, 83% occur in the less developed world due to the absence of screening. To promote the community health awareness of cervical cancer which is preventable. Methods: By internet literature searching (Google Scholar) and textbooks. Results: The primary cause of cervical pre-cancer and cancer is persistent infection with one or more of the oncogenic types of HPV, the most common infection acquired during sexual inter-course, usually early in sexual life. Cervical cancer due to HPV can be prevented by HPV vaccination, participation in a screening program, avoidance of smoking, limitation of sex partners and use of a condom. Three HPV vaccines are available worldwide such as bivalent HPV 16/18 vaccine, quadrivalent HPV 16/18/6/11 L1 virus-like particles vaccine and 9-valent HPV 6/11/16/18/31/33/45/52/58 recombinant vaccine. The HPV test can be done on the same sample of cells collected from the Pap test and it can help to know HPV types. Conclusion: Cervical cancer due to HPV can be prevented by vaccination and the pre-cancerous phase of cervical cancer can be screened by the HPV testing with the Pap test. The community health awareness plays a major role in cervical cancer prevention.

    Introduction: Colorectal cancer is one of the top three most commonly occurring cancer worldwide with more than 1.8 million cases in 2018. In Malaysia, colorectal cancer is the most common cancer in males and the second most common cancer in females. Albeit being the second most common form of cancer in Malaysia, there is a lack of a formal or structured national colorectal cancer screening programme in Malaysia and it remains a low priority in healthcare planning and expenditure in Malaysia. The risk of developing colon cancer is greatly influenced by factors such as lifestyle habits, genetic inheritance, diet, weight, and exercise. Kras, the most frequently mutated oncogene in cancer, occurs in about 50 percent of colorectal cancers. Methods: This study maps the kras gene involved in colon cancer pathway, using bioinformatics applications such as STRING version 11.0 and Cytoscape version 3.7.0 to provide a clear visualisation of all the related and involved proteins and genes that interact with this kras gene in the pathway. Results: The 3391 protein interactions were assembled and visualized in y organic form. Six spe-cific non-overlapping clusters of various sizes, which emerged from the huge network of protein-interactors using MCODE version 1.32 clustering algorithm were found. Biological Networks Gene Ontology (BiNGO) was used to determine two ontologies (molecular function and biological process) involved in the protein network. Based on the resulting protein-protein network interaction map, each interaction plays an important role in the cell cycle, meta-bolic pathways and signal transduction. Conclusion: Understanding these interactions provide insight into cellular activities and thus assist in the understanding of the aetiology of disease.

    Synthesized 2D images can be reconstructed from tomosynthesis images in breast imaging. This study aims to investigate the diagnostic efficacy of synthesized 2D images (C-View) in comparison to full field digital mammography (FFDM) when used with digital breast tomosynthesis (DBT) in multi-ethnic Malaysian population. FFDM and C-View images (n = 380) were independently evaluated by three readers through Breast Imaging Reporting and Data System (BI-RADS) categorisation, breast density and lesion characterisation. Statistical analysis was done comparing sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of C-View + DBT with FFDM + DBT as standard of reference. Very good interreader agreement in BI-RADS category and density assessment between C-View + DBT and FFDM + DBT, with high sensitivity, specificity, PPV and NPV of C-View + DBT when compared with FFDM + DBT. There was comparable PPV between C-View + DBT and FFDM + DBT, with histopathology as gold standard. High level of interreader agreement in BI-RADS category and density assessment for FFDM + DBT and C-View + DBT. There was good agreement between FFDM + DBT and C-View + DBT in mass characterization, and almost perfect agreement in calcification and asymmetric density. 52.2% lower radiation dose incurred when using C-View + DBT. Hence, synthesized 2D images are comparable to FFDM with reduction in radiation dose within the limits of Malaysian multi-ethnic population.

    Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal type of cancer. In this study, we undertook a pairwise comparison of gene expression pattern between tumor tissue and its matching adjacent normal tissue for 45 PDAC patients and identified 22 upregulated and 32 downregulated genes. PPI network revealed that fibronectin 1 and serpin peptidase inhibitor B5 were the most interconnected upregulated-nodes. Virtual screening identified bleomycin exhibited reasonably strong binding to both proteins. Effect of bleomycin on cell viability was examined against two PDAC cell lines, AsPC-1 and MIA PaCa-2. AsPC-1 did not respond to bleomycin, however, MIA PaCa-2 responded to bleomycin with an IC50 of 2.6 μM. This implicates that bleomycin could be repurposed for the treatment of PDAC, especially in combination with other chemotherapy agents. In vivo mouse xenograft studies and patient clinical trials are warranted to understand the functional mechanism of bleomycin towards PDAC and optimize its therapeutic efficacy. Furthermore, we will evaluate the antitumor activity of the other identified drugs in our future studies.

    Ovarian carcinoma is the fifth common cause of cancer death among women in Malaysia, with five-year survival rates of 30%. It has been associated with delayed diagnosis, advanced stage of presentation and poor prognosis due to vague symptoms and lack of effective screening. The continued high fatality rate has underpinned efforts to develop effective screening tests and newer therapies that could impact on prognosis. New insights into proteomic analysis and genomic tests with a better understanding of the target lesion have leading to discovery of new treatment modalities in ovarian carcinoma. We present a 58-year-old lady with Stage IV ovarian cancer who had lower abdominal pain and mass, constipation and voiding frequency for six months duration. Ultrasound guided biopsy revealed serous adenocarcinoma likely ovarian in origin. CT scan showed gross ascites and right ovarian mass with infiltration to adjacent small bowel. Tumour markers CA 125 and LDH were high. She has received neoadjuvant chemotherapy followed by cytoreductive surgery and currently in remission.

    Introduction: Breast cancer is the commonest cancer in Malaysia, predominantly among women under age of 60 and they often presented late. Borneo is home to multi-racial indigenous with heterogeneous background and breast cancer profile can be absolutely unique. This study aims to examine the demographic characteristics and stage at presentation in Sandakan women with newly diagnosed breast cancer. Methods: This is a cross-sectional, retrospec-tive study involving those women who were newly diagnosed with breast cancer from January 2016 to December 2018 in Duchess of Kent Hospital, Sandakan identified via hospital cancer registry and patient records. Only breast cancer with epithelial origin was included. Age, ethnicity and stages at presentation of breast cancer were analysed. Logistic regression was used to study their relationships. Results: 110 women were newly diagnosed as breast cancer. Mean age was 53.5 (SD 12.7), the youngest at 30 and the eldest at 97. Majority (64.6%) were local indigenous wom-en, constituted by 25.4% Sungai, 14.1% Kadazan-Dusun, 12.7% Bugis and the minorities. Chinese women are the main local non-indigenous (32.7%) followed by 2.7% Malay. 52.1% presented at late stages (stage III/IV). Subgroup analysis of T-staging revealed 41.7% had advanced symptoms (T3/T4). Indigenous group was more likely to present at younger ages (OR 12.0; 95%CI 1.5-93.8) and with advanced symptoms (OR 3.1; 95%CI 1.2-8.0). Conclusion: Awareness on breast cancer remains inadequate particularly among indigenous women. Difficult healthcare accessi-bility and incline towards traditional medicine could attribute to late presentation. Outreach awareness programmes are warranted in addition to mobile screening services.
