Rapid urbanisation in Malaysia has led to an increase in anthropogenic activities, inducing degradation of the natural environment. This advocates the necessity of wildlife and resource inventories be conducted at available forested areas, promoting steady improvement in the existing conservation and management plans, especially for threatened taxa such as the small mammals. Small mammals surveys was conducted at Tasik Bera, Ulu Gombak Forest Reserve, Sungkai Wildlife Conservation Centre, Penang Island, and Wang Kelian State Park. Harp traps, mist-nets, cage traps and pitfall traps were set during the surveys. Rhinolophus affinis was the most abundant (N = 61) volant small mammal, followed by Rhinolophus lepidus (N = 27). Meanwhile, the most abundant non-volant small mammal are Leopoldamys sabanus (N = 33), followed by Maxomys rajah (N = 25), and Tupaia glis (N = 22). Two species of shrews, Suncus etruscus and Crocidura monticola were caught as singletons. The results indicated that Ulu Gombak Forest Reserve has the highest species diversity (H’ = 2.754), whereas Penang Island recorded the lowest (H’ = 2.245). The species lists of small mammals generated from the survey will be significant for various stakeholders’ conservation and monitoring plans.   Pembangunan yang semakin pesat di Malaysia telah meningkatkan bilangan aktiviti antropogenik, sekaligus menyebabkan kemerosotan alam sekitar. Ini menunjukkan bahawa perlunya inventori hidupan liar dan sumber alam sekitar dijalankan di dalam kawasan hutan yang sedia ada, untuk mempromosikan peningkatan yang seimbang dalam pelan pemuliharaan dan pengurusan yang sedia ada, terutamanya untuk haiwan yang terancam seperti spesies mamalia kecil. Kajian mamalia kecil telah dijalankan di Tasik Bera, Hutan Simpan Ulu Gombak, Pusat Konservasi Hidupan Liar Sungkai, Pulau Pinang, dan Taman Negeri Wang Kelian. Harp trap, mist net, cage trap dan pitfall trap telah dipasang untuk kajian. Spesies Rhinolophus affinis (N = 61) merupakan spesies yang paling banyak ditangkap, diikuti dengan R. Lepidus (N = 27). Manakala untuk mamalia kecil tidak terbang, species Leopoldamys sabanus merupakan spesies paling banyak (N = 33) diikuti dengan Maxomys rajah (N = 25) dan Tupaia glis (N = 22). Dua spesies cencurut, Suncus etruscus dan Crocidura monticola masing-masing telah ditangkap dengan jumlah satu individu bagi setiap satu spesies. Hutan Simpan Ulu Gombak merekodkan kepelbagaian spesies yang paling tinggi (H’ = 2.754), manakala Pulau Pinang merekodkan nilai yang paling rendah (H’ = 2.245). Senarai mamalia kecil yang telah direkodkan melalui kajian ini merupakan maklumat yang signifikan bagi tujuan pemantauan dan konservasi biodiversiti.

Terminal 11q deletion, known as Jacobsen syndrome (JBS), is a rare genetic disorder associated with numerous dysmorphic features. We studied two cases with multiple congenital anomalies that were cytogenetically detected with deletions on 11q encompassing JBS region: 46,XX,der(11) del(11)(q24). Array comparative genomic hybridization (aCGH) analysis confirmed partial deletion of 11.8–11.9 Mb at 11q24.1q25 (case 1) and 13.9–14 Mb deletion at 11q23.3q25 together with 7.3–7.6 Mb duplication at 12q24.32q24.33 (case 2). Dysmorphism because of the partial duplication of 12q was not overtly decipherable over the Jacobsen phenotype except for a triangular facial profile. Aberrant chromosome 11 was inherited from phenotypically normal father, carrier of balanced translocation 46,XY,t(11;12)(q23.3; q24.32). In the present study, both cases had phenotypes that were milder than the ones described in literature despite having large deletion size. Most prominent features in classical JBS is thrombocytopenia, which was absent in both these cases. Therefore, detailed functional analysis of terminal 11q region is warranted to elucidate etiology of JBS and their clinical presentation.

In this study, gel polymer electrolytes (GPEs) were prepared using polyacrylonitrile (PAN) polymer, ethylene carbonate (EC), propylene carbonate (PC) plasticizers and different compositions of tetrapropylammonium iodide (TPAI) salt.
