Two new species and one subspecies of the genus Cechetra Zolotuhin Ryabov, 2012 are described from South-East Asia. Cechetra bryki sp.n. is described from Nepal, Myanmar (Burma), southwestern China and northern Vietnam. This species is most closely related in habitus, male genitalia morphology and COI mtDNA to the sympatric species, C. lineosa (Walker, 1856) and C. scotti (Rothschild, 1920) in habitus, male genitalia morphology and COI mtDNA. Cechetra inconspicua sp.n. is described from Peninsular Malaysia, Borneo and Sumatra. In habitus, it is closest to C. lineosa and C.subangustata (Rothschild, 1920), but its COI mtDNA (COI-5P "barcode region") is very different from all other species in the genus. Cechetra subangustata continentalis ssp.n. is described from continental Indochina and Taiwan. It differs from the nominotypical subspecies in habitus. Cechetra scotti comb. nov. is transferred to Cechetra from Cechenena Rothschild Jordan, 1903.
The genus Myrmarachne MacLeay, 1839 (Araneae: Salticidae) is one of the most diversified salticid groups in Southeast Asia, with 23 species previously recorded from Borneo. Based on the collections accumulated from 2004 to 2014 in the Lambir Hills National Park, we herein describe six new species: M. amabilis sp. nov., M. hashimotoi sp. nov., M. lagarosoma sp. nov., M. leptosoma sp. nov., M. salaputium sp. nov. and M. tintinnabulum sp. nov. In addition, we describe the female of M. endoi Yamasaki Ahmad, 2013 for the first time. The male-female combination in M. amabilis sp. nov., M. tintinnabulum sp. nov. and M. endoi were confirmed by DNA barcoding.
Platiana Schimmel, 1993 is a moderately large genus in Dimini endemic to South East Asia. Hitherto only four species of this genus were known from Peninsular Malaysia. Here, we describe and figure Platiana cechovskyi sp. nov. from the Cameron Highlands. This species is characteristic by its relatively small body, dark coloration, and strongly serrate antennae which are rarely encountered in Dimini. An identification key to the Platiana species from Peninsular Malaysia as well as a distribution map for all known species are provided.

An integrative taxonomic analysis of the Ptychozoon lionotum group across its range in Indochina and Sundaland recovers P. lionotum sensu lato Annandale, 1905 as paraphyletic with respect to P. popaense Grismer, Wood, Thura, Grismer, Brown, Stuart, 2018a and composed of four allopatric, genetically divergent, ND2 mitochondrial lineages. Multivariate and univariate analyses of continuous and discrete morphological and color pattern characters statistically and discretely diagnose each lineage from one another and together, with maximum likelihood and Bayesian inference analyses, provide the foundation for the recognition of each lineage as a new species-hypotheses corroborated with a Generalized Mixed Yule Coalescent species delimitation analysis. Ptychozoon cicakterbang sp. nov. ranges throughout Peninsular Malaysia to Pulau Natuna Besar, Indonesia; P. kabkaebin sp. nov. is endemic to northern and central Laos; and P. tokehos sp. nov. ranges from southern Thailand south of the Isthmus of Kra northward to Chiang Mai, fringing the Chao Phraya Basin and ranging southward through Cambodia to southern Vietnam. Ptychozoon lionotum sensu stricto ranges from northwestern Laos through southern Myanmar to eastern India. The phylogeographic structure within each species varies considerably with P. lionotum s.s. showing no genetic divergence across its 1,100 km range compared to P. cicakterbang sp. nov. showing upwards of 8.2% sequence divergence between syntopic individuals. Significant phylogeographic structure exists within P. tokehos sp. nov. and increased sampling throughout Thailand may require additional taxonomic changes within this species.

B. takamukui (Matsumura, 1927), comb. n., B. karenkensis (Matsumura, 1930), comb. n., B. rhipiptera (Wileman West, 1928), comb. n., B. chi (Roepke, 1946), comb. nov., B. salakia (Schaus, 1922), comb. n., B. marginis (Fang, 1991), comb. nov. and B. dentata (Wileman, 1910), comb. nov. The lectotype is designated for Lithosia hypoprepioides Walker, 1862. Adults, male and female genitalia of all species are illustrated.
The Asian Prostate Cancer (A-CaP) Study is an Asia-wide prospective registry study for surveying the treatment outcome of prostate cancer patients who have received a histopathological diagnosis. The study aims to clarify the clinical situation for prostate cancer in Asia and use the outcomes for the purposes of international comparison. Following the first meeting in Tokyo on December 2015, the second meeting in Seoul, Korea 2016, the third meeting in Chiang Mai, Thailand, on October 2017, the fourth meeting was held in Seoul, again on August 2018 with the participation of members and collaborators from 13 countries and regions. In the meeting, participating countries and regions presented the current status of data collection and the A-CaP office presented a preliminary analysis of the registered cases received from each country and region. Participants discussed ongoing challenges relating to data cleaning and data up-dating which is the next step of the A-CaP study following the data collection phase between 2016 and 2018. There was specific difference in term of the patient characteristics, and initial treatment pattern among East Asia, Southeast Asia and Turkey, and Jordan. Finally, a close relationship between prevalence of PSA test and disease stage of the patients at diagnosis in Japan and Malaysia was discussed.
Makanan berasaskan kacang soya terkenal di Asia sejak beribu tahun dahulu dan ia tidak hanya diiktiraf sebagai makanan tradisi tetapi mempunyai potensi untuk kesihatan. Kajian ini dijalankan untuk menentukan penerimaan, kesukaan dan kadar penggunaan produk soya dalam kalangan pengguna di Semenanjung Malaysia. Seramai 330 responden telah terlibat dalam kajian ini. Mereka terdiri daripada pelajar universiti dan masyarakat umum yang berumur 18 tahun ke atas. Setiap responden diminta untuk mengisi borang soal selidik dengan seliaan penyelidik. Kajian menunjukkan bahawa 56% responden lebih menyukai susu soya berbanding dengan produk soya yang lain seperti taufufa (16%), kicap (9%), tempeh (8%), tauhu telur (7%) dan tauhu soya (4%). Sebahagian besar responden (>50%) percaya produk soya boleh mengurangkan risiko kanser dan osteoporosis. Sebanyak 89.4% responden makan tauhu soya. Sementara itu, 63.9% responden makan tauhu telur dan 42.2% suka tauhu telur yang digoreng. Lebih daripada 80% responden meminati warna, aroma, rasa dan tekstur tauhu telur.
The Asian seabass (Lates calcarifer) is one of the most economically important aquaculture fish species in South East Asia. While the biology of the Asian seabass is widely studied, relatively little information is available at the molecular level. This lack of molecular information represents one obstacle to rapid progress in the study of immune responses particularly under aquaculture conditions. In light of this situation, we have undertaken an expressed sequence tag (EST) project on the Asian seabass spleen, the secondary lymphoid organ, for the identification of immune-related genes. A
total of 2932 ESTs were generated and grouped into 1063 unique transcripts (UTs), which consisted of 104 consensi and 959 singletons. Of these, 51.3% (545/1063) matched to previously identified genes, while 48.7% (518/1063) showed no match. Of the 545 homologous UTs, 102 (9.6%) can be putatively identified as immune-related genes. The identification of the putative immune-related genes provides a meaningful framework in the effort to comprehend the Asian seabass immune system that may lead to an increase in the understanding of the defense mechanisms of and our abilities to
manage this fish species.
The relationship between β-diversity and latitude still remains to be a core question in ecology because of the lack of consensus between studies. One hypothesis for the lack of consensus between studies is that spatial scale changes the relationship between latitude and β-diversity. Here, we test this hypothesis using tree data from 15 large-scale forest plots (greater than or equal to 15 ha, diameter at breast height ≥ 1 cm) across a latitudinal gradient (3-30o) in the Asia-Pacific region. We found that the observed β-diversity decreased with increasing latitude when sampling local tree communities at small spatial scale (grain size ≤0.1 ha), but the observed β-diversity did not change with latitude when sampling at large spatial scales (greater than or equal to 0.25 ha). Differences in latitudinal β-diversity gradients across spatial scales were caused by pooled species richness (γ-diversity), which influenced observed β-diversity values at small spatial scales, but not at large spatial scales. Therefore, spatial scale changes the relationship between β-diversity, γ-diversity and latitude, and improving sample representativeness avoids the γ-dependence of β-diversity.
This study examines the projected precipitation extremes for the end of 21st century (2081-2100) over Southeast Asia (SEA) using the output of the Southeast Asia Regional Climate Downscaling/Coordinated Regional Climate Downscaling Experiment - Southeast Asia (SEACLID/CORDEX-SEA). Eight ensemble members, representing a subset of archived CORDEX-SEA simulations at 25 km spatial resolution, were examined for emission scenarios of RCP4.5 and RCP8.5. The study utilised four different indicators of rainfall extreme, i.e. the annual/seasonal rainfall total (PRCPTOT), consecutive dry days (CDD), frequency of extremely heavy rainfall (R50mm) and annual/seasonal maximum of daily rainfall (RX1day). In general, changes in extreme indices are more pronounced and covering wider area under RCP8.5 than RCP4.5. The decrease in annual PRCPTOT is projected over most of SEA region, except for Myanmar and Northern Thailand, with magnitude as much as 20% (30%) under RCP4.5 (RCP8.5) scenario. The most significant and robust changes were noted in CDD, which is projected to increase by as much as 30% under RCP4.5 and 60% under RCP8.5, particularly over Maritime Continent (MC). The projected decrease in PRCPTOT over MC is significant and robust during June to August (JJA) and September to November (SON). During March to May (MAM) under RCP8.5, significant and robust PRCPTOT decreases are also projected over Indochina. The CDD changes during JJA and SON over MC are even higher, more robust and significant compared to the annual changes. At the same time, a wetting tendency is also projected over Indochina. The R50mm and RX1day are projected to increase, during all seasons with significant and robust signal of RX1day during JJA and SON.
In 2018, our team collected aerosols samples from five poultry farms in Malaysia. Influenza D virus was detected in 14% of samples. One sample had an 86.3% identity score similar to NCBI accession number MH785020.1. This is the first molecular sequence of influenza D virus detected in Southeast Asia from a bioaerosol sample. Our findings indicate that further study of role of IDV in poultry is necessary.
A case of chronic fatigue syndrome (CFS) like illness was identified recently. Diagnosis CFS is commonly used in the western countries but not in Malaysia or other parts of Asia. It is probably because the diagnosis of neurasthenia has gradually disappeared especially in the United States and United Kingdom. Neurasthenia is dropped in the DSM-111 and DSM-1V but is still retained in the 10th International Classification of Disease. This paper is reporting the case and discussing the definition of chronic fatigue syndrome. (JUMMEC 2000; 2:103-104).
We systematically review the health-financing mechanisms, revenue rising, pooling, purchasing, and benefits, in the Association of Southeast Asian Nations (ASEAN) and the People's Republic of China, and their impact on universal health coverage (UHC) goals in terms of universal financial protection, utilization/equity and quality. Two kinds of sources are reviewed: 1) academic articles, and 2) countries' health system reports. We synthesize the findings from ASEAN countries and China reporting on studies that are in the scope of our objective, and studies that focus on the system (macro level) rather than treatment/technology specific studies (micro level).The results of our review suggest that the main sources of revenues are direct/indirect taxes and out of pocket payments in all ASEAN countries and China except for Brunei where natural resource revenues are the main source of revenue collection. Brunei, Indonesia, Philippines, Malaysia, and Viet Nam have a single pool for revenue collection constituting a national health insurance. Cambodia, China, Lao, Singapore, and Thailand have implemented multiple pooling systems while Myanmar has no formal arrangement. Capitation, Fee-for-Service, DRGs, Fee schedules, Salary, and Global budget are the methods of purchasing in the studied countries. Each country has its own definition of the basic benefit package which includes the services that are perceived as essential for the population health. Although many studies provide evidence of an increase in financial protection after reforming the health-financing mechanisms in the studied countries, inequity in financial protection continue to exist. Overall, the utilization of health care among the poor has increased as a consequence of the implementation of government subsidized health insurance schemes which target the poor in most of the studied countries. Inappropriate policies and provider payment mechanisms impact on the quality of health care provision. We conclude that the most important factors to attain UHC are to prioritize and include vulnerable groups into the health insurance scheme. Government subsidization for this kind of groups is found to be an effective method to achieve this goal. The higher the percentage of government expenditure on health, the greater the financial protection is. At the same time, there is a need to weigh the financial stability of the health-financing system. A unified health insurance system providing the same benefit package for all, is the most efficient way to attain equitable access to health care. Capacity building for both administrative and health service providers is crucial for sustainable and good quality health care.
Sistem arus di ionosfera khatulistiwa terdiri daripada elektrojet khatulistiwa (EEJ) dan suria senyap (Sq). Arus EEJ merupakan satu jalur arus yang mengalir ke arah timur sepanjang kawasan dip khatulistiwa. Arus Sq pula adalah gegelung arus yang mengalir di hemisfera utara dan selatan bumi pada arah yang bertentangan. Kajian ini bertujuan untuk menganalisis kesan aktiviti matahari terhadap profil latitud sistem arus, khususnya di kawasan Asia Tenggara. Data yang digunakan dalam kajian ini merangkumi data geomagnet daripada lima stesen magnetometer dalam rangkaian MAGDAS iaitu stesen Muntinlupa (MUT), Cebu (CEB), Davao (DAV), Manado (MND) dan Pare Pare (PRP). Keamatan arus EEJ yang paling tinggi adalah pada waktu tengah hari sekitar 1000 dan 1100 LT semasa solar minimum dan kajian ini telah menganalisis sistem arus daripada 1000 hingga 1400 LT. Analisis menunjukkan bahawa ribut geomagnet yang berlaku pada 23 April 2008 adalah disebabkan oleh letusan jirim korona (CME) yang memberikan peningkatan kepada nilai arus pada hari tersebut. Peningkatan yang ketara dapat dilihat pada arus di stesen hemisfera selatan, iaitu stesen MND dan PRP. Berdasarkan analisis yang dilakukan, ia turut mendapati bahawa ribut geomagnet memberikan peningkatan kepada nilai arus walaupun di luar waktu puncak. Selain itu, profil arus ini turut dibandingkan dengan profil arus pada hari senyap iaitu pada 21 April 2008.
More than half of the world's population live in Asia-Pacific. This region is culturally diverse, with significant disparities in terms of socio-economic status, provision of health care and access to advanced technology. The medical use of ionising radiation is increasing worldwide and similarly within the Asia-Pacific region. In this paper, we highlight the current status in usage of ionising radiation in medicine in the region, and review the legal framework, implementation and activities in radiation protection. Asia-Pacific countries are active in strengthening radiation protection by promoting education and training. Various projects and activities initiated by international organisations such as the IAEA, WHO and ICRP have provided stimulation in the region, but more work is needed to continue to improve protection practices.
This review includes the situation of nutrition labelling and claims in six countries in South-East Asia: Brunei, Indonesia, Malaysia, Philippines, Singapore and Thailand. With the exception of Malaysia, there is no mandatory nutrition labelling requirements for foods in these countries except for special categories of foods and when nutritional claims are made for fortified or enriched foods. Nevertheless, several food manufacturers, especially multinationals, do voluntarily label the nutritional content of a number of food products. There is, therefore, increasing interest among authorities in countries in the region to start formulating regulations for nutrition labelling for a wider variety of foods. Malaysia has proposed new regulations to make it mandatory to label a number of foodstuffs with the four core nutrients, protein, carbohydrate, fat and energy. Other countries have preferred to start with voluntary labelling by the manufacturers, but have spelt out the requirements for this voluntary labelling. The format and requirements for nutrition labelling differ widely for countries in the region. Some countries, such as Malaysia, closely follow the Codex guidelines on nutrition labelling in terms of format, components to be included and mode of expression. Other countries, such as the Philippines and Thailand, have drafted nutrition labelling regulations very similar to those of the Nutrition Labeling and Education Act (NLEA) of the United States. Nutrition and health claims are also not specifically permitted under food regulations that were enacted before 1998. However, various food products on the market have been carrying a variety of nutrition and health claims. There is concern that without proper regulations, the food industry may not be certain as to what claims can be made. Excessive and misleading claims made by irresponsible manufacturers would only serve to confuse and mislead the consumer. In recent years, there has been efforts in countries in the region to enact regulations on nutrition claims. Recently enacted regulations or amendments to existing regulations of almost all the countries reviewed have included provisions for nutrition claims. Malaysia is in the process of gazetting regulations to clearly stipulate the permitted nutrition claims and the conditions required to make these claims along the guidelines of Codex Alimentarius Commission. Only two countries in the region permit health claims to be made - Indonesia and Philippines. Other countries in the region are following developments in Codex and examining the need for allowing these claims. There are more differences than similarities in the regulations on nutrition labelling and claims among countries in the South-East Asian region as no previous efforts have been made to address these. Hopefully, through this first regional meeting, countries can initiate closer interaction, with a view to working towards greater harmonization of nutrition labelling and health claims in the region.
