Introduction

The escalation of land use conversion to agriculture is one of the key drivers of the decline in critical ecosystem function and biodiversity. Vast areas of forest in the tropics have been cleared and planted for various agricultural crops including oil palm, which is one of the most important crops in many tropical countries especially Indonesia and Malaysia. The establishment of oil palm plantations is an incredibly intensive process, involving converting native vegetation, usually degraded land or logged over forest to a plantation, often leaving behind fragmented and isolated rainforest in an oil palm matrix

Genomic sequencing and analyses of Lymantria xylina multiple nucleopolyhedrovirus

<p>Abstract</p> <p>Background</p> <p>Outbreaks of the casuarina moth, <it>Lymantria xylina </it>Swinehoe (Lepidoptera: Lymantriidae), which is a very important forest pest in Taiwan, have occurred every five to 10 years. This moth has expanded its range of host plants to include more than 65 species of broadleaf trees. LyxyMNPV (<it>L. xylina </it>multiple nucleopolyhedrovirus) is highly virulent to the casuarina moth and has been investigated as a possible biopesticide for controlling this moth. LdMNPV-like virus has also been isolated from <it>Lymantria xylin</it>a larvae but LyxyMNPV was more virulent than LdMNPV-like virus both in NTU-LY and IPLB-LD-652Y cell lines. To better understand LyxyMNPV, the nucleotide sequence of the LyxyMNPV DNA genome was determined and analysed.</p> <p>Results</p> <p>The genome of LyxyMNPV consists of 156,344 bases, has a G+C content of 53.4% and contains 157 putative open reading frames (ORFs). The gene content and gene order of LyxyMNPV were similar to those of LdMNPV, with 151 ORFs identified as homologous to those reported in the LdMNPV genome. Two genes (Lyxy49 and Lyxy123) were homologous to other baculoviruses, and four unique LyxyMNPV ORFs (Lyxy11, Lyxy19, Lyxy130 and Lyxy131) were identified in the LyxyMNPV genome, including a <it>gag-like </it>gene that was not reported in baculoviruses. LdMNPV contains 23 ORFs that are absent in LyxyMNPV. Readily identifiable homologues of the gene <it>host range factor-1 </it>(<it>hrf-1</it>), which appears to be involved in the susceptibility of <it>L. dispar </it>to NPV infection, were not present in LyxyMNPV. Additionally, two putative <it>odv-e27 </it>homologues were identified in LyxyMNPV. The LyxyMNPV genome encoded 14 <it>bro </it>genes compared with 16 in LdMNPV, which occupied more than 8% of the LyxyMNPV genome. Thirteen homologous regions (<it>hr</it>s) were identified containing 48 repeated sequences composed of 30-bp imperfect palindromes. However, they differed in the relative positions, number of repeats and orientation in the genome compared to LdMNPV.</p> <p>Conclusion</p> <p>The gene parity plot analysis, percent identity of the gene homologues and a phylogenetic analysis suggested that LyxyMNPV is a Group II NPV that is most closely related to LdMNPV but with a highly distinct genomic organisation.</p

1-[2,2-Bis(1,3-benzimidazol-1-ylmeth­yl)-3-bromo­prop­yl]-1,3-benzimidazole

The title compound, C26H23BrN6, has been synthesized as a potential ligand for the construction of metal–organic frameworks. The three benzimidazolyl groups present three potential coordination nodes. The dihedral angles between the benzimidazole ring systems are 74.03 (10), 66.49 (9) and 74.09 (9)°. The structure contains large voids, which contain highly disordered solvent mol­ecules that may be CH3CH2OH. Since the solvent mol­ecules could not be located, the PLATON/SQUEEZE procedure [Spek (2009 ▶). Acta Cryst. D65, 148–155] was used

Case study 11: The use of camera traps to monitor medium to large mammals in HCVAs, Wilmar Oil Palm Plantation, Miri, Sarawak

Wilmar has a long-term collaboration with UNIMAS since 2013 to conduct biodiversity monitoring (including camera trapping for monitoring mammals) at its oil palm estates in the Miri Division in Sarawak. The biodiversity monitoring sites consist of three HCVAs that are located within the estates. These forested areas are designated as HCVAs as they contain substantial proportions of remnant native biodiversity. Camera trapping has been extensively used in wildlife research as it is highly effi cient and cost-effective for monitoring mammals (Tobler et al., 2008; Rovero et al., 2014), especially in the case of tropical rainforests where species can be cryptic and elusive in nature (Azlan, 2006). Three mammalian surveys via camera trapping were conducted in the Wilmar Oil Palm Plantation, Miri, Sarawak in years 2013-2014, 2014-2015 and 2018-2020. Study sites consisted of three High Conservation Value Areas (HCVAs) that are located within the estates of Saremas 1, Saremas 2 and Segarmas. Bukit Durang is the largest HCVA measuring 989.9ha, Segarmas HCVA is 147.9ha and the smallest is Saremas 1 HCVA at 116.3ha (see accompanying map). Bukit Durang HCVA is classifi ed as HCV 1 while Saremas 1 and Saremas 2 HCVAs are classed as HCV 4. These forests were designated as HCVAs as they contain substantial proportions of remnant native biodiversity. The HCVs are managed by Wilmar’s Eco Management Unit (EMU) under the Sustainability Division and fi nanced by the individual estates. Wilmar Oil Palm Plantation is certifi ed by MSPO, ISCC and RSPO

Takayasu's Arteritis Treated by Percutaneous Transluminal Angioplasty with Stenting in the Descending Aorta

A 17-yr-old young woman was referred to our hospital with a 2-yr history of claudication of the lower extremities and severe arterial hypertension. Physical examination revealed significantly different blood pressures between both arms (160/92 and 180/95 mmHg) and legs (92/61 and 82/57 mmHg). The hematological and biochemical values were within their normal ranges, except for the increased erythrocyte sedimentation rate (83 mm/hr) and C-reactive protein (6.19 mg/L). On 3-dimensional computed tomographic angiography, the ascending aorta, the aortic arch and its branches, and the thoracic and, descending aorta, but not the renal artery, were shown to be stenotic. The diagnosis of type IIb Takayasu's arteritis was made according to the new angiographic classification of Takayasu's arteritis, Takyasu conference 1994. Percutaneous transluminal angioplasty with stenting was performed on the thoracic and abdominal aorta. After the interventional procedures, the upper extremity blood pressure improved from 162/101 mmHg to 132/85 mmHg, respectively. She has been free of claudication and there have been no cardiac events during 2-yr of clinical follow-up

Association Between Acid-Sensing Ion Channel 3 Gene Variants and Balance Impairment in People With Mild Traumatic Brain Injury

Introduction: Dizziness and balance impairment are common symptoms of mild traumatic brain injury (mTBI). Acid-sensing ion channel 3 (ASIC3) is expressed in the vestibular and proprioceptive systems and associated with balance functions. However, whether the genetic variants of ASIC3 are associated with people who suffer dizziness and balance impairment after mTBI remained unknown.Materials and methods: A total of 200 people with mTBI and 109 non-mTBI controls were recruited. Dizziness, balance functions, and the ability to perform daily activities were assessed by Dizziness Handicap Inventory (DHI), and objective balance functions were investigated by the postural stability test. Three diseases-related genetic variants of ASIC3 were determined through polymerase chain reaction and followed by restriction fragment length polymorphism. The Student's t-test and Mann-Whitney U-test were used for normal and abnormal distributed data, respectively. The regression was applied to adjust gender and age. The normality of continuous data was evaluated by Shapiro-Wilk test.Results: In the mTBI people, the rs2288645-A allele carriers exhibited a significantly worse physical domain DHI score (A-allele carriers: 11.39 ± 8.42, non-A carriers: 8.76 ± 7.87, p = 0.03). The rs4148855-GTC deletion carriers an exhibited significantly worse overall postural stability (GTC deletion carriers: 0.53 ± 0.33, non-carriers: 0.46 ± 0.20, p = 0.03). In the controls, rs2288646-A allele carriers were significant worse in the medial-to-lateral postural stability (A-allele carriers: 0.31 ± 0.17, non-A carriers: 0.21 ± 0.10, p = 0.01).Conclusion: The present study demonstrated that ASIC3 genetic variants were associated with certain aspects of balance functions and dizziness questionnaires in people of mTBI and non-mTBI. It provides a possible evidence that ASIC3 could be a new target for the management of the balancing disorders. However, further investigations are warranted to elucidate the underlying mechanisms and clinical significance

Intra-host competition and interactions between Soybean mosaic virus (SMV) strains in mixed-infected soybean

Abstract Over the past two decades, the dominant Soybean mosaic virus (SMV) strain in South Korea has changed from G5 to G7H. To examine the dominance of G7H, intra-host competition between G7H and G5 was evaluated in soybean plants infected with a mixture of SMV strains. The distribution patterns of the two SMV strains in soybean plants inoculated with G7H, G5 and G7H/G5 were investigated at designated time points by RT-PCR/RFLP analysis, which enables the specific differentiation of low concentrations of SMV strains and the detection of mixed infection at any given time. When leaves of &apos;Kwangankong&apos; and &apos;Tawonkong&apos; were infected with both strains, the upper leaves had only the G7H strain in simultaneous infections. In sequential inoculations, the leaves exhibited mosaic symptoms caused by G7H, and the G5 strain was not detected in plants pre-inoculated with the G7H strain before inoculation with the G5 strain. In the reverse treatment, both G5 and G7H were present at every vegetative stage. In addition, interactions between the virulence and dominance of G7H, G5, and G1, a less virulent strain, were investigated. Three landrace soybeans were co-inoculated with G7H/G5, G7H/G1, G5/G1, and G7H/G5/G1 sets. There was no significant difference between virulence and dominance. These results demonstrate the dominance of G7H in mixed infections and could explain the prevalence of G7H in South Korea

Simultaneously enhancing adsorbed hydrogen and dinitrogen to enable efficient electrochemical NH3 synthesis on Sm(OH)3

The electrochemical N2 reduction reaction (ENRR), driven by renewable electricity and run under ambient conditions, offers a promising sustainable avenue for carbon-neutral NH3 production. Yet, to efficiently bind and activate the inert N2 remains challenge. Herein, effective and stable electrochemical NH3 synthesis on Sm(OH)3 via enhanced adsorption of hydrogen and dinitrogen by dual integration of sulfur dopants and oxygen vacancies (VO) is reported. The resulting S-doped lanthanide electrocatalyst attains both a good NH3 yield rate, exceeding 21 μgNH3 h−1 mgcat.−1, and an NH3 faradaic efficiency of over 29% at −0.3 V (vs reversible hydrogen electrode) in an H-type cell using a neutral electrolyte, figures of merit that are largely maintained after 2 days of consecutive polarization. Density functional theory calculations show that the adsorption energy barrier of N2 on S-Sm(OH)3(VO) is greatly lowered by the introduction of VO. In addition, the S sites improve the adsorption of hydrogen produced via the Volmer reaction, which is conducive to the formation of the *N–NH intermediate (i.e., the potential determining step, PDS) on adjacent Sm sites, and thereby significantly promotes the reaction kinetics of ENRR. The PDS free energy for the catalyst is comparable with the values at the peak of the ENRR volcano plots of leading transition metal catalyst surfaces
