    The most commonly used techniques of alpha and gamma spectrometry were performed to measure
    210Pb activity in marine sediment core as a comparison. Alpha analytical technique measured the
    activity of 210Pb from it’s in-grow grand-daughter 210Po after a chemical separation, assuming
    radioactive equilibrium between the two radionuclides. Meanwhile, gamma analysis technique
    allows direct measurement, non-destructive and no preliminary chemical separation. Through the
    comparison, it is found that both alpha and gamma analysis techniques were slightly difference.
    Overall, the results from alpha analytical technique were basically higher than those from the
    gamma analytical techniques. Some logical argument had been discussed to explain this situation.
    In routine analysis, the analytical technique used should be chosen carefully based on advantages
    and disadvantages of the each technique and analysis requirements. Therefore, it is recommended to
    determine exactly the needs and purpose of analysis and to know the sample history before decide
    the appropriate analytical technique

    Sains Malaysiana, 2014;43:161-168.
    Growth performance, sexual reproduction and clonal propagation of I. japonica population in contrast reciprocal habitats; Open Area of Forest Edge (OAFE) and Bamboo Forest (BF) on Jinyun Mountain were studied to understand the adaptability of growth and reproductive of I. japonica in different habitats. The results were as follows: quantitative characteristics of growth and clonal propagation of I. japonica at genet (a group of genetically identical individuals, consists of whole ramets) level and at ramet (a unit composed of a shoot and root, with independent morphological and physiological traits in the same genet) level were higher in BF. However, quantitative characteristics of sexual reproduction at genet and ramet level were higher in OAFE. Biomass and allocation also showed the same trend as quantitative characteristics. Reproductive components (at ramet level) were significantly different and had trade- off in contrast reciprocal habitats. Allocation to clonal propagation and sexual reproduction of mother ramet was significantly negative correlation with allocation to daughter ramet (especially in BF). There was a trade-off between reproduction components (allocation to sexual reproduction and clonal propagation of mother ramet) in OAFE. Therefore, it showed predominantly sexual reproduction in OAFE and clonal propagation in BF. The results indicated that the contrast environmental stress shaping growth performance and reproduction variation of I. japonica in genet and ramet level in contrasting habitats might pronounce adaptive population differentiation among forest habitats.

    Sains Malaysiana, 2014;43:1821-1826.
    A reciprocal transplant-replant experiment was carried out to investigate the clonal plasticity and local specialization of OAFE population (O type) and BF population (U type) of a clonal rhizome herb Iris japonica in contrasting reciprocal heterogeneous habitats on Jinyun Mountain. U Population had better performance of plant size and clonal propagation (including allocation to clonal propagation, daughter ramet and fine rhizome) in different reciprocal heterogeneous habitats than O population. Both the population origin and reciprocal spatial heterogeneous habitat had effects on clonal ramets and biomass of clonal components of experimental plants. The plasticity of clonal growth had difference in clonal components to balance High light-Low soil resources (water) (HL) or Low light-High soil resources (LH) due to the ecological isolation of the two I. japonica populations. Our findings indicated that two major types of patterns of spatial covariance of resources can have different effects on the growth and local variation of clonal plants.

    MyJurnal
    A study to measure the concentrations of long-lived radionuclides of the uranium and thorium series in naturally occurring radioactive materials (NORM) wastes was carried out using gamma spectrometry and neutron activation analysis methods. It was found that radionuclides in the NORM wastes of the oil/gas production and ores/minerals processing industries were not in equilibrium. The 226 Ra/ 238 U and 228 Ra/ 232 Th ratios were between 0.001 and 2220 indicating that the concentrations of daughters radionuclides ( 226 Ra, 228 Ra) were very low or very high compared to the parent radionuclides ( 238 U, 232 Th) in the NORM wastes.

  5. Luminescent Cu4I4-Cu3(Pyrazolate)3Coordination Frameworks: Postsynthetic Ligand Substitution Leads to Network Displacement and Entanglement
    Zhan SZ, Li M, Zheng J, Wang QJ, Ng SW, Li D
    Inorg Chem, 2017 Nov 06;56(21):13446-13455.

    Six daughter complexes based on two-dimensional (2-D) luminescent Cu4I4-Cu3Pz3(Pz = pyrazolate) coordination networks, which exhibit an uncommon Cu4I4L3L' (L = pyridine; L' = acetonitrile, pyridine, pyrazine, 1,4-diazabicyclo[2.2.2]octane, triphenylphosphine, none) local configuration, were prepared through a postsynthetic modification method starting from a parent complex (L' = NH3). This work has successfully implemented the single-site substitution of Cu4I4-based coordination frameworks, which have rarely been reported for isolated Cu4I4-type compounds, by taking advantage of the solvent-assisted ligand substitution strategy recently developed in metal-organic framework (MOF) chemistry. Such a procedure not only resulted in the variation of local geometry in the Cu4I4units but also led to interlayer network displacement and entanglement. Particularly, an interesting topological transformation (from 2-D to 2-D → 3-D interpenetration) occurred when linear bidentate linkers (e.g., pyrazine and 1,4-diazabicyclo[2.2.2]octane) are inserted between the 2-D layers. Moreover, the variation in the L' sites can effectively tune the emission colors, ranging from green to orange (λemmax540-605 nm at room temperature). The photoluminescence origins are tentatively assigned to be a mixture of3MLCT and3XLCT, different from that of the well-studied isolated Cu4I4-type complexes.

    Girling JE, Hawthorne SCJ, Marino JL, Nur Azurah AG, Grover SR, Jayasinghe YL
    J Pediatr Adolesc Gynecol, 2018 Oct;31(5):459-467.
    PMID: 29655581 DOI: 10.1016/j.jpag.2018.04.001
    STUDY OBJECTIVE: No studies have specifically considered paternal understanding of menstruation. This study aimed to establish the degree of understanding of fathers of adolescent girls with menstrual symptoms relative to mothers.
    DESIGN AND SETTING: This was a cross-sectional survey-based study. Adolescent patients attending an outpatient gynecology clinic for dysmenorrhea and/or heavy menstrual bleeding and their parents were invited to complete surveys.
    PARTICIPANTS: Sixty surveys were completed (24 of 40 daughters, 20 of 40 mothers, 16 of 40 fathers).
    INTERVENTIONS AND MAIN OUTCOME MEASURES: Surveys aimed to test parents' understanding of menstrual symptoms and potential medications, as well as fathers' concerns with their daughters' health.
    RESULTS: The fathers' knowledge of menstrual symptoms was poorer than mothers, although most knew heavy menstrual bleeding (15/16, 94%) and mood swings (14/16, 87%). Many parents answered "don't know" or did not answer questions about potential consequences of medications, although parents were clearly concerned about side effects. Most fathers (13/16, 81%) were open to discussing menstrual concerns with daughters; however, only 54% (13/24) of daughters were open to such discussions. Of fathers, 81% (13/16) were sympathetic/concerned, 56% (9/16) felt helpless, and 13% (2/16) were frustrated when daughters were in pain. When asked about effects, 88% (14/16) of fathers (79% [15/20] of mothers) were worried about their daughter's welfare and 63% (10/16) (55% [11/20] of mothers) about schooling.
    CONCLUSION: We present, to our knowledge, the first insight into fathers' knowledge of their daughters' menstrual health. Overall, parents have an incomplete picture of menstrual symptoms. Even in this cohort, which could be expected to be well informed because of their daughters' attendance at a tertiary hospital, it is clear that further knowledge would assist them caring for their daughters.

  11. Ethnic differences in parents' coresidence with adult children in Peninsular Malaysia
    Chan A, Davanzo J
    J Cross Cult Gerontol, 1996 Mar;11(1):29-59.
    PMID: 24389944 DOI: 10.1007/BF00116264
    In this paper we use data from the Second Malaysian Family Life Survey (MFLS-2) to examine the extent to which ethnic differences in the living arrangements of the older population in Peninsular Malaysia can be explained by ethnic differences in demographic and socioeconomic characteristics. We also investigate whether the three main ethnic groups of Malaysia differ in the extent to which their living arrangements are influenced by these factors. For the married, the higher incidence of remarriage and lower housing costs for Malays each contribute importantly to their lower coresidence rates. The relatively poorer health of Indians and better health of Malays also contribute to the ethnic differences in coresidence rates for the married, as does the higher incidence of daughter-only families among Malays. The explanatory variables considered here explain less of the ethnic differences in coresidence rates for the unmarried.

    Trends in Undergraduate Research, 2018;1(1):0-0.
    MyJurnal
    This article examines the impact of gender socialization in Malaysian families, especially on daughters regarding their perception towards work inside and outside the home. Hence, this study utilized in-depth interview as part of the qualitative methods to obtain quality data needed. The study establishes, that patriarchy environment, especially one with the classic model of ‘breadwinner father, housewife mother’ creates a pressure on women to bear more household responsibility. Thus, the dominant gender ideologies are entangled with ‘motherhood mandate’ and ‘superior feminine virtue’ that is associated with the reason women left the labour force. It was equally necessary to point out here that other agents of socialization such as media, peers and education played its part as well and influenced the respondent’s conformity to patriarchal values.

    Malaysian Journal of Public Health Medicine, 2015;15(2):1-7.
    MyJurnal
    Ageing anxiety is commoner among women compared to men. However, little is known on the possible contributing factors towards the development of ageing related anxiety among Malaysian women. This study aimed to explore ageing anxiety among the middle-aged women in Malaysia in facing the ageing process. Series of 6 focus group discussions (FGD) were conducted involving a total of 36 women aged between 35 and 59 years old. Each FGD consisted of 5 to 7 respondents and was conducted for an average of 1 to 2 hours. The respondents were selected using the maximum variation sampling method focussing on five age categories, between 35 to 39, 40 to 44, 45 to 49, 50 to 54 and 55 to 59 years old. Representative from several residential areas in the area of Putrajaya Federal Territory and Seri Kembangan, Selangor were involved in the selection of respondents. The interviews revealed that, majority of the respondents were seriously thinking of the possible negative experiences associated with ageing and being old, but very few experiencing ageing anxiety. Three main themes that were identified to contribute to the ageing anxiety were issues related to caregiving at old age and fear of loneliness, the welfare and care of their children when they are old and eventually die and also physical changes that occurred with ageing process. These themes were not specifically associated with any particular age groups, marital or income status. However, the development of the ageing anxiety was found to be related to their personal experiences and observations from the surrounding community. The findings show that women in Malaysia are still emphasizing on the importance of traditional caregiving system, where elderly parents are looked after by the children or extended family members rather than living in formal institutions. Despite the important role of formal institutions in the care of elderly people in the future, it is still negatively perceived. With the shrinking of the size of nuclear family and massive involvement of women in employment sector, more elderly will be expected to reside in formal institutions in the near future. Relevant authorities should be made aware on the importance to maintain the quality of care in the formal institution for elderly, in order to tackle the negative perceptions.

    Von Hippel-Lindau (VHL) disease is a rare autosomal dominantly inherited multisystem disorder characterised by the development of a variety of benign and malignant tumours. We report a case of VHL disease that was inherited by a daughter from her father, who both presented at a young age with progressive headache and were found to have a posterior fossa haemangioblastoma (HB) on magnetic resonance imaging (MRI). Multiple benign pancreatic and renal cysts were also noted in both patients.

  15. Fulltext FGFR3 mutation increases bladder tumourigenesis by suppressing acute inflammation
    Foth M, Ismail NFB, Kung JSC, Tomlinson D, Knowles MA, Eriksson P, et al.
    J Pathol, 2018 Nov;246(3):331-343.
    PMID: 30043421 DOI: 10.1002/path.5143
    Recent studies of muscle-invasive bladder cancer show that FGFR3 mutations are generally found in a luminal papillary tumour subtype that is characterised by better survival than other molecular subtypes. To better understand the role of FGFR3 in invasive bladder cancer, we examined the process of tumour development induced by the tobacco carcinogen OH-BBN in genetically engineered models that express mutationally activated FGFR3 S249C or FGFR3 K644E in the urothelium. Both occurrence and progression of OH-BBN-driven tumours were increased in the presence of an S249C mutation compared to wild-type control mice. Interestingly, at an early tumour initiation stage, the acute inflammatory response in OH-BBN-treated bladders was suppressed in the presence of an S249C mutation. However, at later stages of tumour progression, increased inflammation was observed in S249C tumours, long after the carcinogen administration had ceased. Early-phase neutrophil depletion using an anti-Ly6G monoclonal antibody resulted in an increased neutrophil-to-lymphocyte ratio at later stages of pathogenesis, indicative of enhanced tumour pathogenesis, which supports the hypothesis that suppression of acute inflammation could play a causative role. Statistical analyses of correlation showed that while initial bladder phenotypes in morphology and inflammation were FGFR3-dependent, increased levels of inflammation were associated with tumour progression at the later stage. This study provides a novel insight into the tumour-promoting effect of FGFR3 mutations via regulation of inflammation at the pre-tumour stage in the bladder.

  16. Fulltext Hypertension in a mountainous province of Vietnam: prevalence and risk factors
    Nam KD, Van NB, Hoang LV, Duc TP, Thi Ha TT, Tuan VT, et al.
    Heliyon, 2020 Feb;6(2):e03383.
    PMID: 32072063 DOI: 10.1016/j.heliyon.2020.e03383
    Background: Hypertension (HTN) significantly contributes to global disease burden, and its prevalence varies amongst different countries and regions. This work is aimed to characterize the hypertensive prevalence and identify risk factors for HTN among the residents in five locations (four communes and one town) of Moc Chau district (Son La province, Vietnam).

    Methods: A cross-sectional study with a cross-sectional methodology was done in selected places from August 2018 to December 2018. We interviewed 197 participants aged equal to or more than 18 years old and measured their blood pressure (BP). Univariate and multivariate logistic regression were applied.

    Results: The overall HTN prevalence of 30.0% was recorded. The differences of HTN prevalence rates were seen by several characters including age groups (p <0.001), accompanying disease (p <0.001) and alcohol drinking (p <0.05). Factors independently associated with hypertension were age (ORs: 3.1 [1.1-9.1]; 6.1 [1.7-22.3]), much salty consumption (OR: 2.6 [1.1-6.6]), alcohol use (OR: 3.1 [1.2-8.1]), HTN familial history (OR: 4.2 [1.3-13.3]) and at least one suffering disease (OR: 5.2 [2.1-12.7]).

    Conclusions: Thus, this study highlighted the high overall HTN prevalence in the Vietnam Northwestern region. Significant differences of HTN rate were observed among several characteristics such as age groups, accompanying disease and alcohol drinking. Age group, much salty consumption, alcohol use, hypertension familial history and at least one suffering disease were risk factors for HTN in study group.

    Kusago T
    Asian Pac Migr J, 1998;7(4):483-523.
    PMID: 12295220 DOI: 10.1177/011719689800700404
    "This paper analyzes the determinants of female migration to export processing zones (EPZs) in Malaysia. A comparison of the individual and household migration models reveals interesting and important contrasting results. First, the role played by the expected net income gains is opposite in the two models: negative in the individual model, positive in the household model. Second, family migration experience is significant in the individual model but not in the household model. Third, attitudes matter to the household decision on a daughter's migration but not in the individual model. These contrasting results suggest that explaining the daughter's migration decision may require more than separation of the individual motives and familial needs."

    Saren MS, Ping EL, Ping WK
    Med J Malaysia, 2020 11;75(6):752-753.
    PMID: 33219193
    The mother of a 9-month-old female infant complained that her child was unable to pass urine at the same time noticing a mass protruding from the vaginal orifice.The infant had a single episode of vaginal bleeding.The primary concern of the mother was the inability of the daughter to micturate. Malignant germ cell tumour arising from an infant vagina is rare and accounts for about 3% of all paedriatic malignancies. These are also referred to as endodermal sinus tumours or yolk sac tumours, and are mostly the commonest form of infant vaginal malignancies encountered. A diagnosis of endodermal sinus tumour was established based on the histology and raised α-fetoprotein levels.These tumours had Schiller-Duval bodies which are primarily blood vessels surrounded by primordial germ cells and were periodic acid shift (PAS) positive diastase resistant hyaline globules which also stain positive with α- fetoprotein which is an important diagnostic feature. Tumours with high α-fetoprotein levels have a poorer prognosis. However, they respond satisfactorily to chemotherapy.
