    AIM: Osteosarcoma is a highly malignant primary bone tumor. The study aim to evaluate the prognostic factors influencing the survival rate in our center.

    METHODS: This was a retrospective cohort study of all patients treated between January 2005 and December 2010.

    RESULTS: We included 163 patients with an age range of 6-59 years (median = 19). The median follow-up was 47 months (range 36-84). The overall survival in patients who completed chemotherapy and surgery (n = 117) was 72% at 2 years and 44% at 5 years. Histologically, 99 (85%) had osteoblastic, 6 (5%) had chondroblastic and 3 (2.5%) had telangiectatic osteosarcoma. Limb salvage surgery was performed in 80 (49%) and 41 (25%) underwent amputation. However, 46 patients (28%) underwent no surgical intervention and incomplete chemotherapy. In total, 38/79 patients had a good chemotherapy response. There was a significantly better survival rate for limb salvage versus amputation. Independent prognostic factors for survival are compliance to treatment and presence of lung metastasis.

    CONCLUSION: The overall survival of osteosarcoma patients was influenced by the presence of pulmonary metastases and compliance to treatment. Histological subtype, different chemotherapy regimens and histological necrosis after chemotherapy did not significantly influence survival. The patients who did not complete treatment had significantly poorer survival.

    The Use of Complementary and alternative medicine (CAM) is a common phenomenon among women with breast cancer in Malaysia. This study examines the prevalence, types, influencing factors and source of information regarding CAM among women with breast cancer, using a cross sectional research design. A purposive sampling was used to recruit 103 women with breast cancer who were attending follow up care at the Radiotherapy and Oncology unit of Universiti Kebangsaan Malaysia Medical Centre. Data was gathered through the use of self–administered questionnaires. Ninety one women identified themselves as CAM users while twelve were non users. Among the CAM users, 57(62.6%) were Malays, 27(29.7%) Chinese and 7(7.7%) Indians. The common types of CAM used were vitamins, nutritional supplements and traditional medicines (TM). CAM was used more frequently upon diagnosis (63.7%) and after completion of conventional treatment (97.8%). With regard to decision-making, most of the women (62.6%) did not make the decision to use CAM and were mostly influenced by their husband and mother (67%). Mother (71.4%), husband (67%), and relatives (56%) were the main sources of information and all values showed significant association with CAM use (p

  4. Fulltext Histological study of gonadal tissues of adult Artemia salina (Linnaeus 1758) and immunohistochemistry by Caspase 3 and HSP70 to detect specific apoptosis markers on gonadal tissues after exposure to TBTCl
    Abushaala NM, Elfituri AM, Zulkifli SZ
    Open Vet J, 2021 02 08;11(1):112-120.
    PMID: 33898292 DOI: 10.4314/ovj.v11i1.17
    Background: Several types of research have been recently carried out on the biological effects of TBTs, including investigations of genitals in invertebrates in response to exposure to TBTs in marine water.

    Aim: The objective of this research was to investigate the acute effects of tributyltin chloride (TBTCl) on gonads in the adult stage of Artemia salina by use normal histology and immunohistochemistry (IHC) (Caspase 3 and HSP70) to see specific apoptosis markers.

    Methods: After exposure of A. salina to different concentrations of TBTCl (25, 50, 100, 200, and 300 ng.l-1), 50 adult A. salina (25 male and 25 female) were selected randomly from each concentration to histologically study the gonads. The gonad tissue was sectioned (5 μm) and some slides were stained with hematoxylin and eosin and others were stained with IHC avidin-biotin complex, and were examined under a light microscope.

    Results: The results showed significant differences (p < 0.05) in histological lesions between different concentrations of TBTCl. The histological lesions in the testis and ovary section were undifferentiated cells, degenerating yolk globules, and follicle cells enveloping the oocyte which was then compared with control tissue, and these effects were found to be increased in females more than in males with the highest concentration of TBTCl. Immunohistochemistry (IHC) showed that positive immunostaining was observed in the testis and ovary as brownish deposits to Caspase 3 and HSP70 antibody after exposure to TBTCl, while the testis and ovary section in control tissue had no immunoreactivity to Caspase 3 and HSP70 antibody; these effects were profoundly increased with the highest concentration of TBTCl in females more than in males. Finally, the histological lesions and IHC (Caspase 3 and HSP70) revealed that the apoptosis and immune system stress of A. salina gonad tissue damage in females were more sensitive to TBTCl toxicity as compared to white males.

    Conclusion: In general, the present study aimed to observe the effects TBTCl on A. salina gonads by using histological sections and IHC (Caspase 3 and HSP70), which were evaluated for the first time and have been proven to possess an important function in apoptosis marker and immune system stress in Artemia. Finally, the specific mechanisms through which TBTCl affects A. salina Caspase 3 and HSP70 expression need further investigation.

  6. Fulltext Blood pressure tracking as an indicator of hypertension risk
    Zulkifli SN
    Singapore Med J, 1992 Oct;33(5):474-7.
    PMID: 1455271
    The significance of high blood pressure to cardio- and cerebrovascular disease is well recognized. The associated mortality and morbidity risks call for multiple approaches to control the development of high blood pressure. Recent studies have shown that precursors of cardiovascular disorders may be apparent from a young age, and that these can persist and contribute to disease in later life. With regard to blood pressure, the phenomenon of persisting at the same rank has been referred to as tracking. This allows for the possible identification of high-risk groups, for whom early intervention can be initiated. In this paper, some of the findings of studies on blood pressure tracking are reviewed.

    Res Vet Sci, 1988 Mar;44(2):251-4.
    PMID: 3387680
    The chromosomes of five gaur (Bos gaurus hubbacki) domestic cattle (B indicus cross B taurus) hybrids (three females, two males) were studied using the leucocyte culture method and centromeric (C) banding technique. All the hybrids had a diploid chromosome number of 2n = 58, made up of two submetacentric autosomes (different in size) and 54 acrocentric autosomes, most of which could be arranged in pairs in descending order of size. The sex (X) chromosomes in females were a pair of submetacentric chromosomes smaller than the submetacentric autosomes. The Y chromosome in males was a small submetacentric chromosome. The C banding patterns were useful in identifying the X and Y chromosomes and the inherited submetacentric autosomes from the gaur sire. Phenotypically, the hybrids resembled normal B indicus cross B taurus calves except for the presence of a distinct hump-like dorsal ridge containing the spinous processes of the third to 11th thoracic vertebrae, upright 'deer-like' ears and long lean legs. The potential of these hybrids as important genetic resources for meat production is stressed.

  9. Fulltext The effects of trans fat diet intake on metabolic parameters and pancreatic tissue in offspring of prenatal bisphenol A exposed rats
    Abulehia H, Mohd Nor NS, Sheikh Abdul Kadir SH, Abdul Aziz M, Zulkifli S
    Sci Rep, 2023 Jun 08;13(1):9322.
    PMID: 37291156 DOI: 10.1038/s41598-023-36043-1
    Bisphenol A (BPA) is a plasticiser used in the manufacturing of many products and its effects on human health remain controversial. Up till now, BPA involvement in metabolic syndrome risk and development is still not fully understood. In this study, we aimed to investigate the effect of prenatal BPA exposure with postnatal trans-fat diet intake on metabolic parameters and pancreatic tissue histology. Eighteen pregnant rats were divided into control (CTL), vehicle tween 80 (VHC), and BPA (5 mg/kg/day) from gestational day (GD) 2 until GD 21, then their weaning rat's offspring were fed with normal diet (ND) or trans-fat diet (TFD) from postnatal week (PNW) 3 until PNW 14. The rats were then sacrificed and the blood (biochemical analysis) and pancreatic tissues (histological analysis) were collected. Glucose, insulin, and lipid profile were measured. The study has shown that there was no significant difference between groups with regard to glucose, insulin, and lipid profiles (p > 0.05). All pancreatic tissues showed normal architecture with irregular islets of Langerhans in TFD intake groups compared to offspring that consumed ND. Furthermore, the pancreatic histomorphometry was also affected whereby the study findings revealed that there was a significant increase in the mean number of pancreatic islets in rats from BPA-TFD group (5.987 ± 0.3159 islets/field, p = 0.0022) compared to those fed with ND and BPA non-exposed. In addition, the results have found that prenatal BPA exposure resulted in a significant decrease in the pancreatic islets diameter of the BPA-ND group (183.3 ± 23.28 µm, p = 0.0022) compared to all other groups. In conclusion, prenatal BPA exposure with postnatal TFD in the offspring may affect glucose homeostasis and pancreatic islets in adulthood, and the effect may be more aggravated in late adulthood.

    Gas-forming infection of the kidneys can affect either the parenchyma or the collecting system. They are known as emphysematous pyelonephritis (EPN) and emphysematous pyelitis (EP) respectively. Bilateral EPN is a fairly established entity and numerous articles about this condition have been published. However, much less is known about bilateral EP. We report a rare case of bilateral EP and a literature review of this disease. A 66-year-old woman with long-standing bilateral staghorn calculi presented with bilateral EP and severe sepsis. She was treated with antibiotics and bilateral double-J stents to drain the upper urinary tracts. She recovered after 1 month of intensive care and medical therapy. Percutaneous nephrolithotomy (PCNL) had been scheduled to treat her staghorn calculi. A literature search on MEDLINE and Google Scholar with the terms "bilateral emphysematous pyelitis" only found 1 case report in English and another 2 reports in the Korean language that discussed bilateral EP. The collective experience of these few cases, including the present case, suggests that bilateral EP runs a more benign course than bilateral EPN. It should be diagnosed as soon as possible with computed tomography (CT) scans of the renal system. Current evidence shows that can be treated successfully with timely antibiotics. Drainage of the collecting system either percutaneously or with placement of double-J stents might facilitate recovery.

    Extracorporeal shock wave lithotripsy (ESWL) is accepted as the gold standard treatment for renal stones that are smaller than 2 cm. Recently, retrograde intrarenal surgery (RIRS) has been introduced as another form of treatment. We report our experience in dealing with renal stones smaller than 2 cm using RIRS as the primary treatment and following failed ESWL.

    Psychiatric symptoms may be related to a silent cerebral infarct, a phenomenon that has been described previously in literature. Acute psychosis or other neuropsychiatric symptoms including depression may present in stroke patients and patients with lesions either within the prefrontal or occipital cortices, or in subcortical areas such as the basal ganglia, thalamus, mid-brain, and brainstem. Psychosis in clinical stroke or in silent cerebral infarction is uncommon and not well documented in the literature. Neurological deficits are the most common presentation in stroke, and nearly a third of patients that suffer a stroke may experience psychological disorders such as depression and anxiety, related to physical disability. The present case report describes an elderly female patient who presented with hallucinations and depressive symptoms, and was discovered to have a recent right frontal brain infarction, without other significant neurological deficits.

    J Anim Physiol Anim Nutr (Berl), 2010 Oct;94(5):641-7.
    PMID: 20050954 DOI: 10.1111/j.1439-0396.2009.00951.x
    High environmental temperature has detrimental effects on the gastrointestinal tract of poultry. An experiment was conducted to determine the effect of acute heat stress on endogenous amino acid (EAA) flow in broiler chickens. A total of 90, day-old broiler chicks were housed in battery cages in an environmentally controlled chamber. Chicks were fed a nitrogen-free diet on day 42 following either no heat exposure (no-heat) or 2 weeks exposure to 35 ± 1 °C for 3 h from days 28 to 42 (2-week heat) or 1 week exposure to 35 ± 1 °C for 3 h from days 35 to 42 (1 week heat). The most abundant amino acid in the ileal flow was glutamic acid, followed by aspartic acid, serine and threonine in non-heat stressed group. The EAA flow in 1-week heat and 2-week heat birds were significantly (p < 0.05) higher than those under no heat exposure (14682, 11161 and 9597 mg/kg of dry matter intake respectively). Moreover, the EAA flow of 2-week heat group was less than 1-week heat group by approximately 36%. These observations suggest that the effect of heat stress on EAA flow is mostly quantitative; however, heat stress may also alter the content of EAA flow qualitatively.

  15. Fulltext Changes in heat shock protein 70 expression and blood characteristics in transported broiler chickens as affected by housing and early age feed restriction
    Al-Aqil A, Zulkifli I
    Poult Sci, 2009 Jul;88(7):1358-64.
    PMID: 19531704 DOI: 10.3382/ps.2008-00554
    An experiment was conducted to determine the effects of 2 types of housing systems and early age feed restriction on heat shock protein (hsp) 70 expression and blood parameters in broiler chickens subjected to road transportation. On d 1, female chicks were housed either in windowless environmentally controlled chambers (temperature was set at 32 degrees C on d 1 and gradually reduced to 23 degrees C by d 21; CH) or in conventional open-sided houses (OH) with cyclic temperatures (minimum, 24 degrees C; maximum, 34 degrees C). Equal number of chicks from each housing system were subjected to either ad libitum feeding or 60% feed restriction on d 4, 5, and 6 (FR). On d 42, all of the birds were crated and transported for 6 h. Birds raised in OH had smaller increases in heterophil:lymphocyte ratios and plasma corticosterone concentrations than those of CH. Subjecting birds to FR dampened heterophil:lymphocyte ratios and corticosterone reactions to transportation. After 4 h of transportation, the OH birds had greater hsp 70 expression than their CH counterparts. Within the CH, the FR chicks showed higher hsp 70 density than those of the ad libitum-fed group. Except for glucose, housing system had a negligible effect on serum levels of cholesterol, potassium, and chloride. Collectively, the results suggest that the improved tolerance to transport stress in OH and FR chicks could be associated with better hsp 70 expression.

    PMID: 20163464 DOI: 10.1111/j.1740-0929.2008.00591.x
    This study was conducted to investigate the effects of feeding fermented fish (FF) to layers on laying performance, and polyunsaturated fatty acid and cholesterol levels in eggs and plasma. A total of 96, 13-week-old Babcock B380 pullets were used in this study. They were randomly assigned to four numerically equal groups with eight replicates per treatment, three birds per replicate. All the birds were housed in individual cages. The dietary treatments were: Control diet, without FF; FF3 diet containing 3% (w/w) FF, FF6 diet containing 6% (w/w) FF and FF9 diet containing 9% (w/w) FF. The study was carried out for 16 weeks inclusive of two weeks of adjustment. Weekly feed intake and egg production were recorded. Blood plasma cholesterol and fatty acid profiles were assayed at the end of the experiment. FF did not enhance (P > 0.05) egg mass but (P < 0.05) decreased egg weight slightly. However, egg yolk cholesterol and plasma cholesterol concentrations were reduced (P < 0.05) by FF. The n-6:n-3 fatty acids ratio in the egg yolk (Control = 7.9, FF9 = 6.2) and plasma (Control = 10.6, FF9 = 6.2) were decreased by feeding FF. Moreover, FF was able to increase (P < 0.05) the docosahexaenoic acid (DHA) concentrations in egg yolk and plasma. In conclusion, this study demonstrated that FF increased DHA and reduced egg yolk cholesterol in poultry eggs.

    PMID: 19266934
    A trial was conducted to determine the influence of short-term exposure to high ambient temperature at 28 and 35 days of age on deep body temperatures (Tb) and subsequent growth of birds until 42 days of age. A total of 90 day old chicks were reared in stainless steel battery cages and were assigned at random into 18 pens of 5 birds each, with 9 pens containing males and another 9 pens containing females. Three treatment groups, each represented by 3 male and 3 female pens, were represented by T1 without any heat exposure, T2 with heat exposure starting at day 28 and T3 with heat exposure starting at day 35. Heat stress was defined as 180 min exposure to 35 +/- 1 degrees C. Tb and body weights were measured at 35, 37 and 39 days of age immediately following heat exposure. Heat stress resulted in higher Tb and Onset of heat stress at 28 days resulted in significantly lower Tb than onset of heat stress at 35 days. Lower Tb in T2 than T3 permitted recovery in body weight at 42 days. Sexes responded similarly to heat stress.

  18. Fulltext Determinants of public attitudes to genetically modified salmon
    Amin L, Azad MA, Gausmian MH, Zulkifli F
    PLoS One, 2014;9(1):e86174.
    PMID: 24489695 DOI: 10.1371/journal.pone.0086174
    The objective of this paper is to assess the attitude of Malaysian stakeholders to genetically modified (GM) salmon and to identify the factors that influence their acceptance of GM salmon using a structural equation model. A survey was carried out on 434 representatives from various stakeholder groups in the Klang Valley region of Malaysia. Public attitude towards GM salmon was measured using self-developed questionnaires with seven-point Likert scales. The findings of this study have confirmed that public attitudes towards GM salmon is a complex issue and should be seen as a multi-faceted process. The most important direct predictors for the encouragement of GM salmon are the specific application-linked perceptions about religious acceptability of GM salmon followed by perceived risks and benefits, familiarity, and general promise of modern biotechnology. Encouragement of GM salmon also involves the interplay among other factors such as general concerns of biotechnology, threatening the natural order of things, the need for labeling, the need for patenting, confidence in regulation, and societal values. The research findings can serve as a database that will be useful for understanding the social construct of public attitude towards GM foods in a developing country.

    The aim of the study is to describe the usage of dietary supplemenu among doctors working in the hospitals in Kota Bharu, Kelantan. The method used was a postal questionaire survey of the doctors, both specialists and medical officers working in these hospitals. The results showed that
    only 28.7% of the doctors are taking dietary supplements. Significantly more female doctors and doctors on long term medication, were taking these supplements. The dietary supplements commonly used were multivitamins and minerals (92.3%), garlic (26.9%), vitamin C (26.9%) and
    lecithin (15.4%). The majority of the doctors who took dietary supplements (60%) felt their health status have improved. These supplements were mostly obtained from hospital pharmacies. Doctors who puchase their own supplements spend between RMIO to RMIZO per month. The main reasons given for taking these supplements were that the doctors jfelt healthier' and to ‘prevent or as a supplementary treatment’ for conditions like hypercholesterolaemia, hypertension, ischaemic heart disease and cancers. There were four doctors who regularly use traditional dietary supplements. Most doctors will generally advice their patients and children to take dietary supplements regularly, as they felt that it is important for health.

    Resistance training (RT) refers to a method of physical conditioning of complex programming which consists of progressive and various training techniques to achieve the desired training goals. An appropriate programme design is the key to success; where exercise selection is one of the critical factors. The selection of exercise will expose different stimulation as in the application of the specific adaptation on imposed demand principle. The option of choosing either bilateral (BI) or unilateral (UNI) exercise is an important decision to perform in the construction of any strength or RT programme. This study aimed to investigate the physiological responses of unilateral versus bilateral acute RT on heart rate (HR), blood pressure (BP) and rate of perceived exertion (RPE). Sixteen (n = 16) trained women with mean age of 23.31 (SD = 1.35) years old went through a total body exercise session for each unilateral and bilateral protocols which both consisted of major muscles group for 80% 1RM, 10 repetitions to maximal effort for 3 sets. The results revealed that all variables examined including HR, systolic blood pressure (SBP), diastolic blood pressure (DBP) and RPE were statistically changed (p < .001) across the times. Apart from that, unilateral and bilateral RT imposed significantly different stimulus on SBP (p < .05).
