Brain tumour occurrence in Malaysia demonstrates an increasing trend from year to year among adults and the second most common cancer among children. Thus, the expansion of numerous research for novel therapy and treatment are necessary. The distribution of brain tumour in a specific population is important to provide substantial information about the current trends for developing new diagnostic technique and research. Consequently, this study is opted to provide descriptive data of brain tumour in Hospital Universiti Sains Malaysia (USM). 217 brain tumour cases were collected from the hospital record between 2011 and 2014. The brain tumour cases were confirmed by pathologists according to WHO classification and grading. Descriptive analysis was evaluated by using Microsoft Excel and IBM SPSS version 22. Gender preponderance in this study shows very little difference. The most common adult primary brain tumour in this study was meningioma (32.7%) followed by glioblastoma (7.8%), a type of diffuse astrocytic tumour. According to age factor, brain tumour distribution pattern shows an increasing trend as the age increases and meningioma is the most common among the elder patients. Secondary tumour takes more than 10% from overall percentage of brain tumour cases. In conclusion, the descriptive data presentation in this study is very helpful to provide baseline information on the current brain tumour occurrence in this region.

Emergency Medicine and Disaster Medicine are two specialties which are similar in the multidisciplinary involvement during the acute phase of the disaster. Recently, there was an increase in the number of disasters in the world but not many physicians are familiar with the principles for dealing with such situations, the unique organizational demands, coordination and the urgent need for medical assistance and relief. This case report delineates our experiences at a tsunami disaster area and the approach to setting up a medical relief team in the affected area. A medical reconnaissance team comprising of an emergency doctor from Hospital Universiti Sains Malaysia (H.U.S.M) and two MERCY Malaysia members was assembled. The team flew to Colombo on day 5 after the tsunami with medical supplies and related materials. The mission started from December 31st 2004 until January 8th 2005. Our surveillance area covered the Southern and Eastern Province with a total distance of 1700 km along the coast. The strategies employed during this medical reconnaissance included risk analysis, devising a resources matrix, developing lines of communication and rapport with other relief teams, Sri Lankan government agencies, and local and international non-government organizations. As a result, our team was able to set up a medical relief camp and distribute the relief items to the tsunami victims. In conclusion, the Disaster Emergency Medical Assistant Team (DEMAT) from H.U.S.M and MERCY Malaysia were able to set up and provide medical relief with our limited resources to a large scale disaster situation.

Artocarpus heterophyllus has been used as traditional medicine. This plant is one of the sources of flavonoid. Flavonoid compounds possessed a wide range of biological properties including anticancer. This study was performed to investigate the cytotoxic effect of flavonoids from A. heterophyllus on H460 and MCF-7 cell lines. The interaction of flavonoids and cisplatin against tested cancer cells was also evaluated. MTT assay was used to determine the cytotoxic effect of flavonoid. Isobologram analysis was selected to evaluate the synergistic effect between flavonoid and cisplatin, their interaction was then confirmed using AO/PI staining method. Amongst of flavonoid compounds, artocarpin exhibited strong cytotoxic effect on both MCF-7 and H460 cell lines with IC₅₀ values of 12.53 µg/mL (28.73 µM) and 9.77 µg/mL (22.40 µM), respectively. This compound enhanced anticancer activity of cisplatin against H460 and MCF-7. The combination produced a synergistic effect on H460 and MCF-7 cell lines with a combination index (CI) values of 0.2 and 0.18, respectively. The AO/PI stained demonstrated that the combination of artocarpin and cisplatin caused morphological changes that indicated apoptosis. Moreover, artocarpanone also significantly increased cytotoxic effect of cisplatin compared to its single concentration with CI below than 1. This result suggested the potency of flavonoid named artocarpin to enhance the anticancer activity of cisplatin on H460 and MCF-7 cell lines.

Syzygium polyanthum is traditionally used as anti-hypertensive agent. However, the nephroprotective effects of S.
polyanthum against hypertensive induced chronic kidney disease has yet to be elucidated. This study was conducted to
determine the antioxidant properties and nephroprotective effects of aqueous extract of S. polyanthum (AESP) in the
spontaneous hypertensive rat model (SHR). The phytochemical constituent was identified using the phytochemical
screening and HPLC methods. The in vitro antioxidant activities were determined by DPPH radical scavenging and
ferric reducing antioxidant power (FRAP) assays. Fifty male SHR were equally divided into 5 groups, (n=10/group);
Untreated-SHR, 20 mg/kg Losartan-treated SHR, 1500 mg/kg AESP treated SHR, 1750 mg/kg AESP treated SHR and
2250 mg/kg AESP treated SHR, while 10 male Wistar Kyoto rats (WKY) were used as control. Losartan and AESP were
administered by oral gavage. Rats were sacrificed after 12 weeks of experiment. The phytochemicals include phenolics,
flavonoids and alkaloids were identified. AESP has high antioxidant activity as shown by antioxidant assays. AESP
normalised systolic blood pressure (p<0.05) and significantly improved renal function (p<0.05). AESP also significantly
reduced malondialdehyde (MDA) (p<0.05) and increased superoxide dismutase (SOD) levels in the serum as compared
to untreated-SHR group (p<0.05). Ultrastructure of renal damage improved by supplementation of AESP. Conclusively,
S. polyanthum is potential to alleviate hypertensive induced chronic kidney disease through its antioxidant properties.

Introduction: There is an increasing demand for additional techniques to diagnose and treat cancer including CRC
or colorectal cancer effectively. Utilizing antibodies as biomarker could contribute to accurate diagnosis of cancer
due to its high specificity and sensitivity. One of the etiologies of CRC progression was proposed as the alterations
of hexosamine biosynthetic pathway which could subsequently influence the rate-limiting enzyme, glutamine-fructose-6-phosphate aminotransferase (GFAT1). These increased enzymatic activities resulted in an elevation of glucose
uptake that provides nutrients facilitating the progression of cancer cells. Therefore, we attempted to determine the
potential of GFAT1 as the biomarker for CRC by correlating its expression with clinicopathological features of the patients. Methods: A total of 132 10% formalin-fixed paraffin embedded tissue were retrieved. Immunohistochemistry
(IHC) was performed on the tissue sections and digital images were subsequently acquired. All the images were automatedly analyzed using IHC Profiler. GFAT1 immunoreactivity in colorectal tissues was calculated using an adapted
H-score formula. Clinicopathological features of the patients were statistically correlated with the status of GFAT1.
Results: Colorectal adenocarcinoma tissues had the significantly highest GFAT1 H-scores with the mean of 103.18
compared to adenoma and non-tumor tissues. There have been no significant associations between clinicopathological characteristics of the patients and the status of GFAT1 except for tumor size. Conclusion: Immunoreactivity of
GFAT1 was significantly different between non-tumorous tissues and adenocarcinoma as well as between adenoma
and adenocarcinoma tissues. GFAT1 could serve as one of the prognostic biomarkers or useful targets.
