OBJECTIVE

Spine MRI is a diagnostic modality for evaluating pediatric CNS tumors. Applying diffusion-weighted MRI (DWI) or diffusion tensor imaging (DTI) to the spine poses challenges due to intrinsic spinal anatomy that exacerbates various image-related artifacts, such as signal dropouts or pileups, geometrical distortions, and incomplete fat suppression. The zonal oblique multislice (ZOOM)–echo-planar imaging (EPI) technique reduces geometric distortion and image blurring by reducing the field of view (FOV) without signal aliasing into the FOV. The authors hypothesized that the ZOOM-EPI method for spine DTI in concert with conventional spinal MRI is an efficient method for augmenting the evaluation of pediatric spinal tumors.

METHODS

Thirty-eight consecutive patients (mean age 8 years) who underwent ZOOM-EPI spine DTI for CNS tumor workup were retrospectively identified. Patients underwent conventional spine MRI and ZOOM-EPI DTI spine MRI. Two blinded radiologists independently reviewed two sets of randomized images: conventional spine MRI without ZOOM-EPI DTI, and conventional spine MRI with ZOOM-EPI DTI. For both image sets, the reviewers scored the findings based on lesion conspicuity and diagnostic confidence using a 5-point Likert scale. The reviewers also recorded presence of tumors. Quantitative apparent diffusion coefficient (ADC) measurements of various spinal tumors were extracted. Tractography was performed in a subset of patients undergoing presurgical evaluation.

RESULTS

Sixteen patients demonstrated spinal tumor lesions. The readers were in moderate agreement (kappa = 0.61, 95% CI 0.30–0.91). The mean scores for conventional MRI and combined conventional MRI and DTI were as follows, respectively: 3.0 and 4.0 for lesion conspicuity (p = 0.0039), and 2.8 and 3.9 for diagnostic confidence (p < 0.001). ZOOM-EPI DTI identified new lesions in 3 patients. In 3 patients, tractography used for neurosurgical planning showed characteristic fiber tract projections. The mean weighted ADCs of low- and high-grade tumors were 1201 × 10−6 and 865 × 10−6 mm2/sec (p = 0.002), respectively; the mean minimum weighted ADCs were 823 × 10−6 and 474 × 10−6 mm2/sec (p = 0.0003), respectively.

CONCLUSIONS

Diffusion MRI with ZOOM-EPI can improve the detection of spinal lesions while providing quantitative diffusion information that helps distinguish low- from high-grade tumors. By adding a 2-minute DTI scan, quantitative diffusion information and tract profiles can reliably be obtained and serve as a useful adjunct to presurgical planning for pediatric spinal tumors.
Plant genetic resources management and pre-breeding in genomics era
Authors: Singh Kuldeep , Kumar Sandeep , Kumar S. Raj , Singh Mohar , Gupta Kavita
Published: July 2019

Plant Genetic Resources (PGR) conserved in gene bank provides genetic variability for efficient utilization in breeding
programmes. Pre-breeding is required for broadening the genetic base of the crop through identification of useful traits in
un-adapted materials and transfer them into better adapted ones for further breeding. So, pre-breeding is a promising
alternative (due to use of un-adapted materials) to link genetic resources and breeding programs. Utilization of PGR in crop
improvement programmes including prebreeding have been very limited. Advances in genomics have provided us with
high-quality reference genomes, sequencing and re-sequencing platforms with reduced cost, marker and QTL assisted
selection, genomic selection and population level genotyping platforms. Further, genome editing tools like, CRISPR/Cas9
and its latest modification base editing technology can be used to generate target specific mutants and are important for
establishing gene functions with respect to their phenotypes through developing knockout mutations. These new genomic
tools can be used to generate, analyse and manipulate the genetic variability for designing cultivars with the desired traits.
The genomic tools has not only accelerated the utilization of PGR but also assisted pre-breeding through rapid selection of
trait-specific germplasm, reduced periods in breeding cycle for confirming gene of interest in intermediate material and
validation of transfer of gene of interest in the cultivated gene pool. In crops, where limited genetic and genomic resources
are available, pre-breeding becomes very challenging. We can say that genomics assisted utilization of PGR and prebreeding
has accelerated the pace of introgression of complex traits in different crop cultivars.and yield plateau has already
been achieved in these cultivars (Chen et al. 2014a). Under these circumstances, use of Plant Genetic Resources (PGR) in
crop improvement programs provides an avenue to solve the problem.
Inbred zebrafish lines: A genetic repository for zebrafish researchers

Published: July 2019

Genetically uniform strains/inbred strains of animals are
used in experiments that demand minimal genetic
background variability and highly reproducible results.
Modern genomic research is heavily dependent on inbred
strains and they are widely used for identification of
quantitative loci that affect evolutionarily and biomedically
important traits, dissection of gene-gene and gene
environmental interaction patterns, toxicity studies,
immunology, reverse genetics, cancer research, etc. In mice,
over 450 inbred strains have been described and in medaka
over 13 inbred strains have been established. Owing to its
numerous attributes zebrafish, Danio rerio, is one of the
widely studied vertebrate model organisms, but comparable
zebrafish inbred strains are not available to the scientific
community. This is because of early onset of inbreeding
depression causing high mortality of embryos and larvae
and biased sex ratio that have been reported from earlier
attempts to produce inbred lines. At CZeBraG-Centre for
Zebrafish Breeding and Genetics Research facility of ICARCIFE,
the inbred lines of zebrafish are being developed.
The strategy followed is intense inbreeding coupled with
strong positive selection for selected traits. The base
population consisted of three wild stocks of zebrafish
collected from rivers of North East India. Using nested
mating design 84 families were produced in F1 generation
and 46 inbred families were produced in F2 generation.
Genetic parameters for growth traits like body weight and
standard length were estimated. The overall heritability for
body weight and standard length was estimated using
animal model and found to be 0.43 ± 0.05 and 0.36 ± 0.04
respectively. Fecundity was also recorded but showed no
significant variation among stocks. Inbreeding depression
was studied by comparing the population means for body
weight and standard length of F1 and F2 generation. The
analysis suggested there was no inbreeding depression.
Genetic monitoring of zebrafish is conducted using
microsatellite markers. New PCR primers were designed
for 20 selected microsatellite loci with high stringency. High
Resolution Melting Curve analysis was used for genotyping
individual zebrafish. In addition to developing inbred lines
the centre is also maintaining the wild zebrafish stocks
and has commenced supply of pedigreed zebrafish for
researchers. In future zebrafish of known inbred levels (12.5
to 50% and above) can be supplied. Currently, the CZeBraG
can house about 10000 adults, with separate facility for
holding individual fish.
Induction and suppression of rice innate immunity
Authors: Malukani Kamal Kumar , Pillai Shakuntala E. , Kachewar Neha R. , Patel Hitendra K. , Sonti Ramesh V.
Published: July 2019

The rice plant is infected by a number of pathogens which
cause significant losses of yield. Plants possess inducible
innate immunity by which they can perceive danger and
mount defense responses. Recognition of the pathogen is
a crucial step in induction of plant immune responses.
Plants can recognise a wide category of molecules related
either to conserved components of pathogen structures,
pathogen secreted molecules or plant damage-associated
molecules. Recognition of these molecules/elicitors by
receptors initiates a signal transduction cascade which
includes phosphorylation of various intermediate proteins,
influx of calcium ions, production of reactive oxygen
species and synthesis of phytohormones. The signaling
intermediates also activate transcription factors leading to
enhanced expression of genes related to defense
associated functions. As immune responses are energy
intensive processes, they are tightly regulated through
phosphorylation/dephosphorylation events or through
degradation of signalling intermediates. The activation of
plant innate immunity suppresses multiplication and spread
of pathogen within the host tissues. In this review we
discuss about key molecular players involved in rice immune
responses.

POTENSI PENGGUNAAN PROTEIN REKOMBINAN FLIC (FLAGELLIN) UNTUK MENINGKATKAN IMUNOGENITAS VAKSIN DNA ANTI KARIES GIGI (Kajian Pustaka)
Authors: Deviyanti Sinta
Published: July 2019

Karies gigi merupakan penyakit infeksi kronis yang menyebabkan pelarutan lokal dan kerusakan jaringan kalsifikasi gigi oleh aktivitas fermentasi dari bakteri terhadap karbohidrat yang dikonsumsi. Streptococcus mutans dianggap sebagai patogen utama pada karies gigi. Berbagai strategi pencegahan karies telah digunakan seperti penyuluhan kesehatan rongga mulut, kontrol plak secara mekanik dan kimia, aplikasi pit dan fissure sealant, penggunaan fluoride. Meskipun demikian, prevalensi karies gigi masih tetap tinggi diseluruh dunia. Upaya pencegahan karies terkini adalah melalui pengembangan vaksin DNA anti karies gigi. Vaksin merupakan bahan kekebalan tubuh biologis yang dirancang untuk menghasilkan perlindungan spesifik terhadap mikroorganisme patogen. Vaksin menstimulasi produksi antibodi pelindung dan mekanisme imun lainnya. Namun imunogenisitas yang rendah dari vaksin DNA, masih menjadi tantangan. Para peneliti menggunakan protein rekombinan FliC (flagellin) yang berasal dari Salmonela sebagai suatu ajuvan mukosa dan aktivator imun yang kuat untuk meningkatkan respon IgG (Imunoglobulin G) serum dan IgA (Imunoglobulin A) saliva. Peningkatan respon spesifik IgG serum dan IgA saliva oleh vaksin DNA yang dikombinasi dengan protein rekombinan FliC pada tikus melalui vaksinasi karies gigi intra nasal, memiliki keterkaitan dengan penghambatan kolonisasi Streptococcus mutans di permukaan gigi dan pengurangan lesi karies secara bermakna.
PRO DAN KONTRA ANTARA HUBUNGAN MENYUSUI DAN EARLY CHILDHOOD CARIES (ECC) (Kajian Pustaka)

Published: July 2019

Karies awal pada masa kanak-kanak atau ECC adalah suatu bentuk awal dari karies gigi yang disebabkan oleh banyak faktor. Hal ini menjadi sasaran utama dalam menentukan promosi kesehatan masyarakat. Menurut World Health Organization (WHO), menyusui merupakan faktor penting untuk menurunkan angka kematian bayi dan malnutrisi. Air Susu Ibu (ASI) harus diberikan secara eksklusif selama 6 bulan dan dilanjutkan dengan pemberian ASI disertai Makanan Pendamping ASI (MPASI) hingga usia 2 tahun. Namun pemberian ASI masih merupakan perdebatan dikalangan peneliti, ada beberapa penelitian yang menemukan bahwa pemberian ASI dalam waktu yang panjang merupakan salah satu faktor risiko terjadinya Early Childhood Caries (ECC). Salah satu penelitian di Jepang pada tahun 2011 menemukan hasil yang signifikan bahwa menyusui merupakan salah satu faktor risiko terjadinya ECC (p=0,0002;OR=6,373). Penelitian lainnya di tahun yang sama menunjukkan 20,7 % prevalensi karies memiliki hubungan yang signifikan dengan pemberian ASI selama 18 bulan atau lebih. Penelitian di Indonesia tahun 2008 menunjukkan bahwa pemberian ASI dalam jangka waktu yang lama merupakan salah satu faktor risiko terjadinya karies (p<0,0001;OR=1.69). Hasil penelitian yang berlawanan pada tahun 2012, menunjukkan kelompok yang tidak diberi ASI mempunyai risiko 4 kali lebih besar untuk menderita ECC dibandingkan dengan bayi yang masih diberi ASI. Tinjauan pustaka ini bertujuan untuk menelaah berbagai penelitian maupun studi ilmiah tentang pro dan kontra hubungan ASI dan ECC. Data yang diperoleh dikumpulkan dari berbagai jurnal, database dan artikel seperti The Journal of The American Dental Association, PubMed, Medline dan BMC Oral Health.
Fusion to the Lysosome Targeting Signal of the Invariant Chain Alters the Processing and Enhances the Immunogenicity of HIV-1 Reverse Transcriptase

Published: July 2019

Intracellular processing of the antigen encoded by a DNA vaccine is one of the key steps in generating an immune response. Immunization with DNA constructs targeted to the endosomal-lysosomal compartments and to the MHC class II pathway can elicit a strong immune response. Herein, the weakly immunogenic reverse transcriptase of HIV-1 was fused to the minimal lysosomal targeting motif of the human MHC class II invariant chain. The motif fused to the N-terminus shifted the enzyme intracellular localization and accelerated its degradation. Degradation of the chimeric protein occurred predominantly in the lysosomal compartment. BALB/c mice immunized with the plasmid encoding the chimeric protein demonstrated an enhanced immune response, in the form of an increased antigen-specific production of Th1 cytokines, INF- and IL-2, by mouse splenocytes. Moreover, the majority of the splenocytes secreted both cytokines; i.e., were polyfunctional. These findings suggest that retargeting of the antigen to the lysosomes enhances the immune response to DNA vaccine candidates with low intrinsic immunogenicity.

Delineating links among dynamic capabilities, operational capabilities and firm performance
Authors: Dongol Ramesh , Ulusoy Emre
Published: July 2019

Dynamic capabilities influence firm performance by renewing operational capabilities but it is unclearfrom prior studies whether they actually influence firm performance through operational capabilities.Process-quality, process-efficiency and operational flexibility capabilities are three operationalcapabilities. It is also unclear whether a given dynamic capability influences firm performance byrenewing a single operational capability or several of them. Using a firm’s capability to learn fromcustomers as a proxy for a dynamic capability, we find that it renews all three operational capabilities,but a firm’s learning capability influences firm performance only through the process-qualitycapability. We theorize that renewal of former two capabilities serve to maintain existing operations,while renewal of latter capability helps a firm gain an advantage. We term the capability that can usedto simultaneously maintain existing operations and influence performance a dual-purpose capability.Future research should expand to understand how dual-purpose capabilities influence performance.

New data on the dragonfly fauna (Odonata) of the Moulouya River Basin and the Oriental Region, Morocco
Authors: Taybi A.  F. , Mabrouki Y. , Berrahou A. , Sbaa M. , Brochard C.
Published: July 2019

We present new faunistic and distributional data on dragonflies (Odonata) from the east of Morocco, comprising the administrative Oriental Region and the Moulouya River Basin and covering an area of 119,268 km2. A checklist of 47 species belonging to 19 genera and seven families is provided. Pseudagrion s. sublacteum (Coenagrionidae), Aeshna mixta (Aeshnidae), Sympetrum sinaiticum and S. meridionale (Libellulidae) are new for Eastern Morocco, while Paragomphus genei (Gomphidae) is new for the Moulouya watershed. Our surveys yield evidence of breeding of Zygonyx torridus in the Moulouya River, of Sympetrum sinaiticum in the Oriental province, and also of Boyeria rene, which remained unrecorded for more than three decades. We confirm the occurrence of Brachythemis impartita in the study area, by providing new sightings. Our results also revealed the range expansion of several other species whereas some previously known species in the region were not found. We found a clear dominance of the Palearctic elements, mainly Mediterranean, with a high proportion of Ibero-Maghrebian endemic species. This chorotype pattern is similar to patterns observed for other macroinvertebrate groups in the same study area.

Corporate Social Responsibility in Malaysian Organisations: Community Environmental Dimensions and Islamic Perspective.
Authors: Ramli Aliza , Fahmi Fadzlina , Darus Faizah , Mohamed Zain Mustaffa
Published: July 2019

Islamic organizations have the upmost responsibility to ensure that their business operations comply with Shariah principles. However, their approaches to positive actions through Corporate Social Responsibility (CSR) have been varied because of inadequate guidance on the initiatives based on Islamic principles. Despite that CSR has been widely researched and is considered by most as a compulsory practice to be competitive, the current framework for CSR does not incorporate the Shariah principle to explain corporate involvement in social and environmental activities for Islamic organizations. Therefore, utilizing the Islamic CSR framework (i-CSR), this paper explores the current state of CSR initiatives and the motives for stakeholder engagement specifically from the environmental community dimension within Malaysian Islamic organizations. Semi-structured interviews with ten personnel from five Islamic organizations were conducted face to face at the field site. Data analyzed using NVivo software reveals that these organizations have embraced social responsibility beyond its business purpose. The CSR activities are in line with the Shariah principle and are influenced by multiple motivations. The results suggest the importance of an appropriate CSR framework and if adopted, it can be an important element of the overall governance and accountability framework of an Islamic organization.

Behavioral disorders were studied in a comparative aspect in two clinical variants, which are asthenohyperdynamic and astheno-adynamic manifestations of the cerebrastenic syndrome, which is a part of the structure of a neurosis-like state. The age dynamics of behavioral disorders was studied at different stages of ontogenesis, including childhood, prepubertal and puberty, by comparing the obtained data labeled by the subheadings "Period of the first age crisis", "Period of the second age crisis" and "Puberty period". The study found that age response forms reflect the low personal resources of adolescents and the massiveness of negative social influences. As the analysis of clinical material has shown, during puberty, violations in the sphere of cravings became more distinct. Disorders in the sphere of inclinations at this age are closely correlated with the features of the somato-endocrine metamorphosis and with the unfavorable influence of socio-psychological factors. Lack of sexual desire was in direct proportion with a pronounced delay in puberty. Violations in the sphere of sexual desire, reflecting the nondifferentiation of the sexual attitudes of adolescents with delayed puberty, were characteristic of those studied with pronounced volitional immaturity, in particular with such signs as suggestibility, a tendency to imitation. During puberty, the clinical picture of the studied adolescents revealed more clearly the qualitatively new pathological properties of the personality due to the development of excitable, unstable, less often labile and hysterical manifestations. In contrast to psychopathic behavior in sick children and adolescents, no correlation was found between the first signs of deviant behavior and cerebrastenic disorders. In all cases, behavioral disturbances are caused by unfavorable micro-social factors. Based on the follow-up data, the study has found that the studied group of sick children and adolescents is characterized by both favorable dynamics (22) and a negative outcome (20 patients). This suggests that the pubertal period is characterized by a polymorphism of behavioral disorders and is one of the decisive factors in the prognosis of the further development of the child.

Recent days, more and more people are becoming interested in "free-energy". "Free-energy" means the energy sources used freely without to pay. The sources of "free-energy" are sunlight, rainfall, wind energy, wave power, and tidal power. There are other sources of power such as gravity, electrical charge in the atmosphere and ionosphere, and a mass. FESS (Flywheel Energy Storage System) is an attempt to store kinetic energy generated from the rotation flywheel in which the electrical power output from the generator as an input to the motor. Mass flywheel greatly affects the amount of power generated by a generator which will serve as a flywheel device or distributors of energy while at the induction generator to eventually convert mechanical energy into electrical energy and vice versa. In this system design becomes very important for the flywheel can store the kinetic energy. This research aims to design and build mechanisms as a means of comparison FESS flywheel effect of the geometry of the kinetic energy generated. The research method is done by making three different geometric design flywheels, and then analyzed with the help of FESS. From the experimental results, flywheel 1 with a ringtype web-concave generate kinetic energy of 312.30 J and specific energy of 31.23 J / kg, at the flywheel 2 which is type-straight arm kinetic energy gained by 316.73 J and energy specific of 31.67 J / kg and flywheel 3 with a ring-type web-straight kinetic energy obtained by 284.997 J and specific energy of 28.49 J / kg. From the research data we can conclude that each design geometry flywheel has a different contribution to the performance of energy storage.

A Helmet is an equipment that should be used by motorcycle riders. The correct function of helmets is to protect motorcycle riders from head injuries during accident and head collision. Most of helmets existing in markets are produced by helmet factories. Those helmets have to meet certain standards, including the use of materials to construct the helmet lid and the testing processes on the helmet itself. The price of used materials is quite high because those materials are still imported from overseas. It causes the increasing of helmet production cost and the helmet prices in the market become quite expensive. This research aims to find how a biocomposite material (consisting of 85% PP, 10% rice husk and 5% MAPP) can be used as an alternative replacement material for helmet lid preparation. The process is conducted by using finite element software. The result of the testing shows that the test penetration model with 4 mm thickness is not penetrated by indenters. Whereas the result of impact simulation testing of 146.84 g is still classified as a safe limit in accordance with the requirements of SNI 1811-2007 of 300 g.
