METHODOLOGY: This qualitative in-depth interview study was conducted in January 2010 with 30 university students from different faculties, i.e.:International Medical School (IMS), Faculty of Health and Life Sciences (FHLS), Faculty of Business Management and Professional Studies (FBMP) and Faculty of Information Sciences and Engineering (FISE) of the Management and Science University (MSU), Shah Alam, Malaysia. After consent was obtained from all participants, the interviewer wrote down the conversations during the interview sessions. The data obtained were classified into various categories and analyzed manually.

RESULTS: The majority of participants 25 (83%) had heard about cervical cancer, while 16 (53.3%) have never heard of HPV. Only five participants (17%) mentioned that HPV is the cause of cervical cancer. Ten participants (33.3%) did not know any causes. The majority 16 (53.3%) did not know the mode of HPV transmission. The majority of participants 22 (73.3%) mentioned that they had not been vaccinated against HPV. Out of 22, 16 (53.3%) agreed to be vaccinated in the future to protect themselves from cervical cancer and five (17%) participants mentioned they are not willing because of the uncertain safety of the available vaccines and their side effects.

METHODOLOGY: A retrospective study was conducted to evaluate 77 cervical cases collected from the histopathology laboratory of Ipoh hospital from 1st January, 2005, to 31st December, 2006.

RESULTS: Cervical intraepithelial neoplasia (CIN) was found in 33 (42%) cases, CIN III accounting for 27%, and CIN I, CIN II and CIN II-III 5% each. The highest rate for CIN cases was 43% in the 41-50 year age group and the lowest rate was 6% in the group aged 61-70 years. Non-keratinizing and metastatic squamous cell carcinomas (SCCs) accounted for 16% and 13%, respectively, the combination being second in majority (29%), followed by adenocarcinoma (17%). The histopathological results showed CIN I to be characterized by mild papillary projections of the epithelium with some degree of nuclear enlargement, pleomorphism, mild koilocytosis, bionucleated cells and a low nucleo-cytoplasmic ratio. CIN II demonstrated typical squamous epithelium with disorganization of the lower part of the epithelium accompanied by nuclear hyperchromatism, an increased nucleo-cytoplasmic ratio, and scanty mitotic figures. CIN III was characterized by pleomorphic nuclei, atypical cells with mitotic figures, nucleo-cytoplasmic ratio, anisokaryosis and hyperchromasia.

METHODOLOGY: A total of 25 participants agreed to participate in this qualitative study during the period from 20th July 2011 until 24th of September 2011. The proposal of this study was approved by the Ethics Committee of Management and Science University (MSU). Once the participant agreed to be interviewed, date, time and place of the interviews were determined. Consent form was obtained from participants before the interview began. Participants were briefed about the study and its purpose, and after asking their permission, their replies were recorded. The data was organized into themes and analyzed manually.

RESULTS: Twenty-five Malaysian traditional healers participated in this qualitative study. The age of participants ranged between 26 to 78 years old. The majority were in the age group of 31-60 years old, male, Chinese, degree holders with a monthly income ranging from 1,000-5,000 Ringgit Malaysia (RM) and were married (56%, 80%, 48%, 52%, 68%, 84% respectively). The majority defined cancer as having high cholesterol or abscess accumulation. A few of them defined cancer as a type of cell growth. The majority mentioned that food and unhealthy lifestyles are the primary causes of cancer. Surprisingly some of them mentioned that cancer is caused by interference by ghosts. Regarding the diagnosis of cancer, the majority mentioned that they refer their patients to modern physicians' medical report when it comes to diagnosing or treating patients with cancer. The most common cancers that many patients came to seek treatment were breast cancers, followed by colon cancers, liver and lung cancers.

METHODOLOGY: A total number of 612 secondary school girls participated in this study. The questionnaire consists of 38 questions which included 3 sections. The first section is about socio- demography. The Second section is about knowledge and awareness of HPV vaccines. The third section is about practices with associated barriers of HPV vaccination. Verbal consent was obtained from all participants, and data were analyzed using SPSS 13.

RESULTS: A total number of 612 secondary school girl students participated in this study. The mean age was 13.93 ± SD (1.09); minimum age was 13 years old and maximum was 17 years old. The majority of them was Malay, from rural areas and had a family monthly income of RM 3000 or less (91.8%, 53.1%, 69.6%; respectively). The majority of the parents of the school girls were with secondary education level (56.4%). The majority of the participants did not have a family history of cervical cancer (99.0%). The prevalence of HPV vaccination was 77.9% among school girls in Melaka. The majority of the participants were vaccinated in their schools (77.0%). About 69% knew about cervical cancer and 77.6% had ever heard about HPV vaccine. Regarding the factors that influence the practice of uptake HPV vaccine, they were age, race, income, parents' education, knowledge about cervical cancer, heard about HPV vaccine and place of getting the vaccine (p<0.001).

METHODS: A WEHI-3 cell line was used to evaluate the cytotoxicity of BM by MTT. AO/PI and Hoechst 33342 dyes, Annexin V, multiparametric cytotoxicity 3 by high content screening (HCS); cell cycle tests were used to estimate the features of apoptosis and BM effects. Caspase 3 and 9 activities, ROS, western blot for Bcl2, and Bax were detected to study the mechanism of apoptosis. BALB/c mice injected with WEHI-3 cells were used to assess the apoptotic effect of BM in vivo.

RESULTS: BM suppressed the growth of WEHI-3 cells at an IC50value of 14 ± 3 μg/mL in 24 h. The ROS production was increased inside the cells in the treated doses. Both caspases (9 and 3) were activated in treating WEHI-3 cells at 24, 48 and 72 h. Different signs of apoptosis were detected, such as cell membrane blebbing, DNA segmentation and changes in the asymmetry of the cell membrane. Another action by which BM could inhibit WEHI-3 cells is to restrain the cell cycle at the G1/G0 phase. In the in vivo study, BM reduced the destructive effects of leukaemia on the spleen and liver by inducing apoptosis in leukaemic cells.

METHODOLOGY/PRINCIPAL FINDINGS: The cytotoxic effect of thymoquinone was assessed using an MTT assay, while the inhibitory effect of thymoquinone on murine WEHI-3 cell growth was due to the induction of apoptosis, as evidenced by chromatin condensation dye, Hoechst 33342 and acridine orange/propidium iodide fluorescent staining. In addition, Annexin V staining for early apoptosis was performed using flowcytometric analysis. Apoptosis was found to be associated with the cell cycle arrest at the S phase. Expression of Bax, Bcl2 and HSP 70 proteins were observed by western blotting. The effects of thymoquinone on BALB/c mice injected with WEHI-3 cells were indicated by the decrease in the body, spleen and liver weights of the animal, as compared to the control.
