QUO VADIS PANGAN PRODUK REKAYASA GENETIK DI INDONESIA?
Authors: Suwardike Putu
Published: February 2020

Secara obyektif, Indonesia dihadapkan pada tantangan penyediaan pangan berkualitas yang mencukupi kebutuhan seluruh masyarakat di tengah-tengah semakin menyusutnya lahan pertanian produktif, merosotnya daya dukung lahan, keterbatasan air irigasi, dan kondisi iklim tidak menentu. Kebutuhan pangan dikhawatirkan tidak mampu dipenuhi dengan hanya mengandalkan sistem produksi konvensional. Kemajuan dibidang bioteknologi telah memberikan ruang bagi pemulia tanaman melakukan transfer gen dari makhluk hidup berkerabat jauh, seperti dari bakteri ke tanaman. Pada tataran produksi, penerapan bioteknologi mampu menghasilkan tanaman jenis-jenis baru yang lebih unggul, seperti hasil lebih tinggi, lebih efisien menggunakan nutrisi, tahan terhadap cekaman lingkungan tertentu, memiliki kandungan protein lebih tinggi, dan lebih tahan simpan. Namun pada tataran pemanfaatan produk masih menimbulkan pro dan kontra. Pengembangan tanaman transgenik merupakan alternatif solusi terhadap kekhawatiran kerawanan pangan di masa mendatang. Pengujian-pengujian tanaman transgenik dan produk pangan bioteknologi lainnya perlu terus dilakukan. Mengingat beragamnya persepsi masyarakat terhadap produk pangan transgenik, maka pemasangan label pada produk pangan transgenik diperlukan untuk memudahkan masyarakat menentukan pilihannya.
ARE MARKETS ADAPTIVE? EVIDENCE OF PREDICTABILITY AND MARKET EFFICIENCY OF LODGING/RESORT REITS
Authors: Almudhaf Fahad , Aroul Ramya Rajajagadeesan , Hansz J. Andrew
Published: February 2020

We investigate the degree of return predictability of lodging/resort real estate investment trusts (REITs) from January 1994 to May 2016. We test the Martingale hypothesis by using linear (automatic portmanteau and automatic variance ratio with rolling windows) and nonlinear tests (generalized spectral shape tests and Dominguez-Lobato consistent tests). Our findings support the Adaptive Market Hypothesis (AMH) and reveal that returns experience periods of both dependence and independence. We document time-varying predictability of lodging/resort REITs with returns as both initially predictable and subsequently unpredictable throughout the majority of the period of analysis. Moreover, we find that if traders use simple technical trading moving average rules, they can capitalize on the inefficiencies of lodging/resort REITs. Finally, we observe that absolute returns and Sharpe ratios of technical moving average rules outperform a simple buy-and-hold strategy.
Thaddäus Derfflinger’s Sunspot Observations during 1802–1824: A Primary Reference to Understand the Dalton Minimum

Published: February 2020

As we are heading toward the next solar cycle, presumably with a relatively small amplitude, it is of significant interest to reconstruct and describe the past secular minima on the basis of actual observations at the time. The Dalton Minimum is often considered one of the secular minima captured in the coverage of telescopic observations. Nevertheless, the reconstructions of the sunspot group number vary significantly, and the existing butterfly diagrams have a large data gap during the period. This is partially because most long-term observations at that time have remained unexplored in historical archives. Therefore, to improve our understanding on the Dalton Minimum, we have located two series of Thaddäus Derfflinger’s observational records spanning 1802–1824 (a summary manuscript and logbooks), as well as his Brander’s 5.5 feet azimuthal quadrant preserved in the Kremsmünster Observatory. We have revised the existing Derfflinger’s sunspot group number with Waldmeier classification, and eliminated all the existing “spotless days” to remove contaminations from solar elevation observations. We have reconstructed the butterfly diagram on the basis of his observations and illustrated sunspot distributions in both solar hemispheres. Our article aims to revise the trend of Derfflinger’s sunspot group number and to bridge a data gap of the existing butterfly diagrams around the Dalton Minimum. Our results confirm that the Dalton Minimum is significantly different from the Maunder Minimum, both in terms of cycle amplitudes and sunspot distributions. Therefore, the Dalton Minimum is more likely a secular minimum in the long-term solar activity, while further investigations for the observations at that time are required.

To guarantee that the method can be easily applied to the future large-scale structure surveys, we study the possibility of estimating the systematics of the method using the fast simulation method. The major contribution of the systematics comes from the nonzero redshift evolution of the RSD effects, which is quantified by

Vortex Induced Aerodynamic Noise Generation from Wind Turbine Blades
Authors: Bhargava V. , Maddula S. P. , Samala R.
Published: February 2020

An important aerodynamic noise source from lifting surface occurs from trailing edge of an aerofoil as found in wind turbine blades. In this work, semi-empirical method proposed by Brookes, Pope, Marcolini is applied to evaluate trailing edge bluntness vortex shedding noise source. For low Mach number flows (0.1884) and moderate to high chord Reynolds number, 4.73 × 105 - 3.35 × 106, change in sound power level was assessed for trailing edge thicknesses in terms of 0.1%, 0.5% and 1% chord lengths at wind speeds of 8 m/s, 10 m/s. For overall change of trailing edge thickness from 0.1% to 1% chord, an increase in noise levels up to 50 dB was found at low frequencies, while a decrease up to 30 dB was found between mid-band to high frequencies of spectra.

Published: February 2020

BACKGROUND: Mangrove forest is a typical forest found along the coast or river mouth which is affected by tides and salinity. Although polyisoprenoid was widespread in the plant kingdom, the physiological roles of these compounds are not well understood, especially from mangrove plants. It is therefore essential to characterize the polyisoprenoid content under abiotic stress.
AIM: This study aimed to determine the effect of salinity and subsequent fresh water change on polyisoprenoids concentration in Bruguiera cylindrica seedlings.
METHODS: Bruguiera cylindrica planted in a greenhouse for three months under various salinity concentrations. After three months grew under variable salinity, these seedlings were then divided into two treatment groups, and grown for another three months: one continuously in a salt solution and another in fresh water to relieve salt stress. The leaves and roots of B. cylindrica seedlings were harvested after six months of cultivation. The leaves and roots of B. cylindrica seedlings were extracted for polyisoprenoids content and composition analyzed using two-dimensional thin layer chromatography.
RESULTS: Polyisoprenoids composition under salinity and subsequent fresh water with dominating dolichols (more than 90%) were found in leaves and roots of B. cylindrica seedlings referring type I of polyisoprenoid composition. The carbon chain length of dolichols located in the leaves and roots were ranging from C75–C100 and C75–C105, respectively.
CONCLUSION: Dolichol dominated over polyprenol both in B. cylindrical leaves and roots under salinity and subsequent relief supported the previous finding on the predominance dolichols over polyprenols in mangrove plants. The present study suggested the significance of dolichols in the adaptation to cope with salt stress and or water stress.

Published: February 2020

Neste trabalho estudou-se a produção de ácido lático em reator batelada utilizando como substrato soro de leite suplementado com diferentes concentrações de extrato de levedura Saccharomyces cerevisiae (EL), por ação de cultura mista de Lactobacillus acidophilus LA-5®, Bifidobacterium BB-12® e Streptococcus thermophilus imobilizada em esferas de alginato de cálcio, em diferentes temperaturas. Foram estudados dois fatores, concentração (CONC) e temperatura (TPR), sendo adotado os níveis de 0%, 6,5% e 13% para o fator concentração de extrato de levedura e 30°C, 34°C e 38°C para o fator temperatura. Observou-se que células imobilizadas não tiveram a taxa de produção de ácido lático afetada pelo aumento da temperatura de fermentação. Por outro lado, o aumento na concentração de suplementação do meio por EL levou ao aumento da produção de ácido lático. Foi avaliada também a viabilidade das esferas de alginato de cálcio quando reutilizadas para inocular novo meio de cultura. Após cinco ciclos de reutilização as esferas não apresentaram rachaduras e modificação no diâmetro médio. A concentração de ácido aumentou cerca de 157% entre o primeiro e o último ciclo de fermentação.

Published: February 2020

O objetivo neste estudo foi avaliar a composição físico – química e aceitação sensorial de cupcake elaborado em substituição parcial de farinha de trigo pela farinha da fibra de caju (FFC). Foram elaboradas três formulações de cupcake adicionados de FFC, uma padrão (F1) sem FFC e as demais com 5% de FFC (F2) e 12% FFC (F3). Os cupcakes foram elaborados conforme receita padrão. Foi avaliada a composição centesimal das formulações, conforme metodologia da AOAC (2012).  A análise sensorial foi realizada com 70 provadores não treinados. Os atributos avaliados foram aparência, aroma, sabor, textura e aceitação global, mediante escala hedônica estruturada de nove pontos. As médias obtidas de cada análise foram submetidas a análise de variância e quando significativas comparadas pelo teste de Tukey a 5%.  Não houve diferença significativa entre os atributos da análise sensorial, exceto para a aparência do tratamento sem farinha de fibra de caju que foi atribuída maior média entre os provadores. Todas as formulações tiveram um alto nível de aceitação maior que 82%. Os cupcake elaborados com FFC apresentaram maior quantidade de fibras quando comparada com F1. A adição de farinha de fibra de caju mostrou-se uma boa alternativa para o aproveitamento desse subproduto, assim reforça o desenvolvimento de produtos alimentícios com o resíduo do caju, reduzindo perdas e agregando valor e nutrientes a esses produtos.

Published: February 2020

A carne moída é uma fonte de proteína versátil para diferentes preparações. No entanto, a possibilidade de contaminação microbiológica é maior devido a superfície da carne moída estar mais exposta. A contaminação microbiológica, a utilização de antibióticos na produção animal e o uso indiscriminado pelo homem, favorece a aquisição da resistência a antibióticos pelos microrganismos presentes na carne. O objetivo desse estudo foi isolar enterobactérias resistentes a antibióticos, bem como analisar a qualidade físico-química de amostras de carne bovina moída comercializadas em no município de Santos-SP. As bactérias entéricas isoladas da carne moída foram testadas frente aos antibióticos: amoxicilina, ampicilina, estreptomicina, gentamicina, imipenem e penicilina. E dentre essas enterobactérias, 16,6% apresentaram resistência a pelo menos um dos antibióticos e 10% foram resistentes à três antibióticos simultaneamente. Nas análises físico-químicas foram detectadas a presença de gás sulfídrico em todas as amostras e amônia em 96,6% das amostras, sugerindo o início do estado de decomposição da carne. Em relação ao teste de adulteração com sulfito, apenas uma amostra apresentou a possibilidade da adição deste ou outros conservantes na carne. Quanto à determinação do pH, 13,3% estavam acima que preconiza a legislação. O presente trabalho constatou a presença de enterobactérias resistentes à antibióticos na carne moída cuja qualidade físico-química também foi deficiente. Tal fato pode afetar a saúde da população consumidora, principalmente, com a possibilidade da ineficiência do tratamento convencional com antibióticos.

Published: February 2020

O caju, fruta originalmente brasileira, é mais conhecido por sua castanha que pelo pseudofruto. Este é industrialmente pouco utilizado e de valor comercial baixo quando comparado à castanha. O suco puro (cajuína) pode ser utilizado para a obtenção de licor, o que pode aumentar o seu valor agregado e diminuir as perdas da fruta. Com o objetivo de elaborar licor de caju com aceitação sensorial, este produto foi preparado com ou sem adição de aroma de caju idêntico ao natural e avaliado sensorialmente por provadores não treinados, utilizando escala hedônica de 9 pontos. O licor de caju com adição de aroma foi o mais bem aceito pelos provadores nas características de sabor, cor, aroma e impressão global.

O araçá (Psidium Cattleianum Sabine) é uma fruta nativa do Brasil ainda pouco explorada, porém estudos tem demonstrado que o araçá é uma potencial fonte de compostos bioativos, o que tem estimulado seu consumo, tanto na forma in natura como processado. O objetivo desse trabalho foi a extração dos compostos bioativos presentes nos subprodutos da extração da polpa (cascas e sementes). Frutos de araçá Ya-Cy foram coletados, sanitizados e despolpados, os subprodutos da extração das polpas foram liofilizados, moídos e posteriormente extraídos utilizando-se um planejamento fatorial 2² com triplicata no ponto central. As variáveis independentes avaliadas foram: temperatura e tempo de extração: 40, 60 e 80 °C e 30, 60 e 90 minutos, respectivamente. O solvente utilizado tratou-se de uma mistura ternária de água:etanol:acetona 1:1:1 (v/v). O conteúdo de compostos fenólicos e de ABTS variou de 11,74 a 13,35 mg de GAE.g-1 e 155,49 a 184,43 µmol TEAC.g-1 respectivamente, os valores de DPPH variaram de 90,16 a 108,82 µmol trolox.g−1, já o FRAP não apresentou bom ajuste ao modelo, apresentando valor médio de 375,69 micromol Fe(II).g−1. O subproduto da produção de polpa do araçá Ya-Cy se mostrou uma potencial fonte de compostos bioativos com atividade antioxidante.

Published: February 2020

A classificação comercial do caqui pode gerar até 40% de descarte. Estas frutas são pouco aproveitadas devido à falta de informações tecnológicas que possibilitem a sua transformação em produtos com alto valor agregado. O objetivo do trabalho consistiu em avaliar a extração de suco/mosto e os parâmetros de fermentação alcoólica de caqui das cultivares Fuyu (Amagaki) e Kakimel (Shibugaki). O rendimento de extração do suco/mosto foi avaliado em frutos maduros após os seguintes tratamentos [1] trituração e prensagem; [2] trituração, maceração (Pectinex 3XL e Ultrazym AFP-L) e centrifugação; e nos frutos em fase de senescência, com esmagamento manual e maceração enzimática. Análises físico-químicas foram realizadas nos sucos/mostos e nos fermentados de caqui. Os maiores rendimentos de 53 e 40% foram obtidos após trituração dos frutos seguida de uma liquefação enzimática (Ultrazym AFP-L) e centrifugação, para os caquis Fuyu e Kakimel, respectivamente. O mosto/suco despectinizado do caqui Fuyu apresentou coloração levemente amarelada, ao contrário do caqui Kakimel com coloração amarelo dourado. Os teores de açúcar (maior que 17,4 g/100mL) e de nitrogênio (maior que 219 mg/L) do mosto, contagem de leveduras maior que 3,0 x 107 células/mL, o tempo da fermentação alcoólica (9,5-10,5 dias) e o grau alcoólico final (9 °GL) indicam que o caqui apresenta aptidão para elaboração de bebidas alcoólicas. Portanto, este trabalho fornece informações tecnológicas sobre o processamento de bebidas a partir de caqui de descarte.

Biscoitos tipo cookies são amplamente consumidos por todas as idades e sua utilização para a adição de ingredientes sem glúten, permitem agregar valor nutricional e tem boa aceitação pela população, principalmente pelos celíacos. O objetivo deste estudo foi desenvolver cookies com mix de farinhas (uva, linhaça dourada, amido de milho) e avaliar suas características físico-químicas e sensoriais. Para a elaboração dos cookies foram utilizadas cinco formulações distintas em diferentes temperaturas e tempos de assamento. Os resultados obtidos demonstraram que o teor de cinzas e proteínas aumentou com o acréscimo de farinha de uva e os cookies assados a 180 °C apresentaram maior teor de umidade devido ao curto tempo de assamento (5 minutos). Para o teor de lipídios houve diferença significativa e o teor de fibras variou de 3,57 a 7,08% elevando seu teor à medida que a concentração de farinha de uva aumentava. Pelo teste de aceitação, determinou-se que a formulação mais aceita pelos julgadores foi com 6,00% de farinha de uva, na temperatura de 140 ºC.  Ao desenvolver a tabela nutricional da formulação mais aceita, tem-se para uma porção de 30 gramas ou 4 unidades o valor médio de 92 kcal. Com a Análise dos Componentes Principais foi possível verificar a relação entre as análises físico-químicas e sensoriais com boa explicação da variabilidade através dos três componentes principais.

Understanding the Emotional Aspects of Infertility: Implications for Nursing Practice
Authors: Sherrod Roy Ann
Published: February 2020

Approximately 10% to 15% of childbearing-age couples experience infertility. Infertility has multiple aspects, including physical, emotional, financial, social, and psychological effects. Although most health care professionals are more aware of problems related to physical aspects of infertility, the difficulties and needs that arise from the emotional aspects are often more significant for couples. Thus, it is crucial that health care professionals, particularly nurses, understand these needs. This article provides some practical information to help nurses do just that.

An expanded model of recovery-based group work places the use of scrapbooks and portfolios within the context of a practice model that seeks to increase general and social self-efficacy in these women. Memory scrapbooks, lifecourse scrapbooks, and recovery portfolios are defined; their differential use in group work is described; and ways group members can use the tools to strengthen their sources of self-efficacy are explored.
Urban Stream Syndrome and Contaminant Uptake in Salamanders of Central Texas
Authors: Diaz Peter H. , Orsak Erik L. , Weckerly Floyd W. , Montagne Mike A. , Alvarez David A.
Published: February 2020

We studied the ecological health of springs experiencing varying levels of urban development to assess impacts to rare endemic salamanders (Eurycea spp.) of Central Texas. We evaluated measures of invertebrate species richness, water quality, and contaminant uptake by salamanders to determine how springs and their inhabitants were being affected by urban growth and changing land-use patterns. The number of environmental contaminants present and concentrations of contaminants increased in both water and salamander tissues with increasing age of the developments (i.e., years postconstruction) and increasing levels of impervious cover (e.g., roads) in urban watersheds compared with nondeveloped sites. We conclude that urbanization and associated increases in pollutant loading in watersheds can result in a loss of spring biodiversity and the accumulation of persistent and potentially toxic pollutants in salamanders. Although we detected generally low levels of pollutants, the altered water quality and invertebrate composition observed at springs, coupled with the changing hydrology and chronic contaminant exposure inherent in urban landscapes, is cause for concern, with potential implications for the long-term health, survival, and recovery of salamanders.
Lost in the Jungle of Terminology: Reciprocity in Different Fields of Study
Authors: Koch Lennart
Published: February 2020

Reciprocity in tandem is usually treated like a norm of behaviour for mutual help and equal distribution of time dedicated to each language. While there has been a long-standing debate about reciprocity in different fields of study and related terms like cooperation, interaction, alignment or conversational adjustments in communication, until recently the tandem principle was almost never related to the debate in other disciplines. And although reciprocity in many of these fields is considered to be of fundamental relevance, only a few contributions have been made to the proposal of definitions which could serve as an operational basis for further research. A discussion about the relation of the norm of reciprocity with other conversational norms or maxims is also missing. This paper discusses different understandings of reciprocity and similar terms in the light of reciprocity in tandem.
Teletandems are not the Online Version of Face-to-Face Tandems; Here’s Why
Authors: Debras Camille
Published: February 2020

Teletandems are not just the online transposition of face-to-face tandem interactions. Although both online and offline tandems share similarities (reciprocity, autonomy, peer interaction), they constitute different types of interactions, because offline and online interactions are of a fundamentally different nature. Face-to-face interactions are characterized by copresence, mutual monitoring, centrality of focus as well as by specific gaze and gesture dynamics. Mutual monitoring through gaze is a crucial element of face-to-face interaction. Conversely, online interactions are characterized by physical distance and the possibility of shielding involvement; polyfocality, and specific kinesic dynamics. Mutual gaze is impossible, gesture use and perception is highly constrained, physical distance or proximity is exaggerated and facial expressions are put to the fore. The two types of tandems develop intercultural pragmatic competence and complementary skills: face-to-face tandems emphasize closeness and contact, while teletandems improve digital literacy, especially so as to succeed in navigating the post-cultural, digital “third space”.

Authors: Wahyu Nirbito , Nabila Alifani , Firhan Hardian R.
Published: February 2020

Strong earthquake affects buildings to response in huge dynamic oscillating motion. In a teaching hospital that full of patients, medical personnel and medical treatment facilities as well as many modern advanced equipment may be in very dangerous situation due to this building response. To reduce the human victims, equipments and infrastructure damages, a kind of base isolation is added to the foundation of the hospital building. Inspite of oscillation motion as a vertical cantilever, this foundation base isolation of the hospital building is applied and designed to give the response of the earthquake vibration waves in lateral motion. To find out the optimum properties of the base isolation, some calculations of the response from vibration parameters are observed. The Keq value is 415,120,000 N/m and the total massive Mass of the hospital is 148,057,364 kg as well as the highest vibration force is 108,136,030.2 N. This study work deals with simplified modelling using FEA in ANSYS software. The aim is to see the simulation based on the calculation of the analysis and whether the response is as expected.

Published: February 2020

Humic acid - functionalized silver nanoparticles (HA-AgNPs) were successfully synthesized and used to detect Cu (II) ions in aqueous solutions. The HA-AgNPs was shown to have an average hydrodynamic diameter of 101.4 nm and a polydispersity index of 0.447. The absorbance spectra of HA-AgNPs showed the characteristic local surface plasmon resonance (LSPR) peak of AgNPs at 408.3 nm. Addition of Cu (II) in the HA-AgNPs led to their agglomeration as evidenced by the change in their surface morphology and their corresponding optical absorbance spectra. The synthesized HA-AgNPs showed a strong linear response for Cu (II) concentrations in the range of 0.00 – 1.25 mM with a limit of detection (LoD) of 4.4428 ± 0.1091 mg L-1, a limit of quantification (LoQ) of 14.8094 ± 0.3636 mg L-1, and a limit of blank (LoB) of 0.1214 ± 0.0065 mg L-1. Statistical analysis showed that this calibration curve could be used to quantify Cu (II) concentrations within a 95% confidence level. Furthermore, HA-AgNPs was found to be selective for Cu (II) detection based on the selectivity study against common metal ions found in drinking water. This shows that the synthesized HA-AgNPs can be used as an environment-friendly colorimetric nanosensor for rapid and point-of-need quantification of Cu (II) ions in aqueous media.

Authors: Swasono Yogi Angga
Published: February 2020

An effort to improve electrical property of Polypropylene (PP)/Clay nanocomposite was conducted. Carbon black (CB) was introduced into PP/Clay to enhance that property as required for conductive polymer composites (CPCs) application. The compositions of CB on PP/Clay were varied at 3, 5, and 7 percent hundred resin (phr). In this research, all composites were prepared by melt mixing using an internal mixer at 222 °C, 83 rpm, and 10 minutes. A compatibilizer, PP-grafted-Maleic Anhydride (PP-g-MA), was used to facilitate dispersion of clay layers and CB particles on PP matrix. The electrical property of composite was evaluated from their surface resistivity using insulation tester. Meantime thermal-oxidative stability property was analyzed from oxidative induction time (OIT) data using Differential Scanning Calorimetry (DSC) instrument. The presence of CB dramatically decreased surface resistivity of PP/Clay from 6.98 x 1013 ohm to 7.35 x 106 ohm by adding CB 7 phr. OIT of PP/Clay dropped 155% compare with neat PP. On the other hand, the addition of CB 7 phr into PP/Clay improved OIT of PP/Clay up to 22 %. The interlayer structure of clay was investigated using X-ray Diffraction (XRD) to find out the synergistic effect between clay and CB. Actually, clay interlayer spacing did not change due to the addition of CB.

Published: February 2020

ObjectiveKnowledge regarding arterial variations is important during surgeries, intra-arterial injections, venipuncture and imaging of the upper limb. Our objective was to document brachial artery variations. MethodsWe studied 54 upper limb specimens during routine dissection. The anterior compartment of the arm, cubital fossa and the forearm were dissected and the pathway and the distribution of the brachial artery and its branches were documented. ResultsVariations of the brachial artery anatomy were noted in 3 specimens (5%). Unilateral high bifurcation of brachial artery was noted in two specimens on the left side. In one of these, bifurcation was directly from the axillary artery at the axilla just proximal to the formation of the median nerve. Here the brachial artery divided into its terminal radial and ulnar branches. In the other specimen, the brachial artery bifurcated into radial and ulnar arteries at the level of the mid humerus. In the other specimen, the brachial artery was seen to trifurcate into radial, ulnar and common interosseus arteries at the level of the neck of the radius. ConclusionsHigh brachial artery bifurcation and trifurcation of the brachial artery in the upper arm was noted in this study. Reporting of such variations in different populations is important for the practicing clinician during diagnostic and surgical procedures.

Published: February 2020

IntroductionSpleen is an organ enriched in vascular and lymphoid tissue located in left hypochondrium. It has morphological variations which may be misinterpreted as a disease condition involving the spleen. Therefore, knowledge on such morphological differences in a population is vital to distinguish normal variations from the disease conditions. Objective of this study was to identify the morphological variations such as notches, fissures and lobulations in cadavers. MethodsTen-percent formalin fixed, selfdonated cadaveric human spleens (n=13) in the Department of Anatomy, Faculty of Medicine, University of Colombo were included in the present study. In the study population, male to female ratio was 10: 3 with age ranging from 26 to 95 years. The morphological features such as shape, notching of borders, fissures and lobulations were photographed, dissected and analyzed according to Michels NA classification. The morphological types of spleens were categorized by measuring hilar lengths. ResultsNotches were present in superior (n=8), inferior (n= 1) or intermediate (n=2) borders in ten spleens, while notches were absent in three. Five spleens had supernumerary notches. Six spleens contained fissures in both visceral and diaphragmatic surfaces. Four spleens had more than three lobules, while three had more than one hilum. The splenic types included compact, intermediate and distributed, which accounted for four, three and sixrespectively. ConclusionInconstant location of notches, presence of supernumerary notches, fissures and lobules were a common morphological variation observed.
Hip geometry on femoral neck bone strength; a review article
Authors: Alwis G.
Published: February 2020

Introduction: Low bone strength of the hip, which depends on both bone mass and bone geometry, leads to risk for fragility hip fracture. Anatomical adaptations of the proximal femoral structure are important to maintain higher bone strength because they predict the fracture risk independent of bone mass. Therefore, it is crucial to evaluate the bone strength of proximal femur to predict the likelihood of fragility fracture risk based on both bone mass and geometric adaptations, as well as the biomechanical strength of femoral neck (FN). Aim: To discuss the literature on geometric indices and biomechanical indices of the proximal femur to estimate FN strength. Material and methods: Dual energy xray absorptiometry (DXA) based hip structural analysis (HSA) technique derived indices of FN geometric adaptations and biomechanical strength at FN and their impact on FN bone strength were explored using the existing literature. Bone mineral content (BMC, gram) and areal bone mineral density (aBMD, g/cm2) can be measured using the HAS technique. The simple hip geometric indices such as hip axis length (HAL), femoral neck length (FNL), neck shaft angle (NSA), FN diameters, FN width and biomechanical indices such as cross-sectional moment of inertia (CSMI, cm4), section modulus (Z, cm3) and cross-sectional area (CSA, cm2) can be estimated using the HSA technique to estimate FN bone strength. Conclusion: Estimation of FN bone strength by HSA based geometric adaptations and biomechanical strength indices provides better understanding of bone strength at FN. HAL and FN bone size with BMD provide better hip fracture predictability.

Published: February 2020

IntroductionThe preservation of DNA in old skeletal remains is reported to be very low in a tropical country like Sri Lanka due to prevailing climatic and environmental conditions such as high temperature, high rainfall and high humidity, etc. In this study, extraction of DNA from old skeletal remains dated back to 15 – 40 years was attempted by using previously published extraction protocols. Materials and MethodsA 15-years-old humerus (15Y) excavated from Kuliyapitiya area in Kurunegala district and the 40-yearsold tibia (40Y) received from Department of Anatomy, Faculty of Medical Sciences, University of Sri Jayewardenepura were used to extract old DNA. Human mitochondrial HVS I region of extracted DNA was amplified in PCR using four overlapping first round primers and second round nested primers respectively. A second-round nested PCR was performed. PCR amplification success was verified upon electrophoresis in 2% agarose gels. Results and AnalysisDNA bands were obtained with correct size ranges for all systems in both first and second round PCR products of amplified DNA extract of old bones 15Y and 40Y from modified phenolchloroform method. DNA bands were obtained from all four systems for 40Y bone DNA extract from DNA investigation Kit; QIAGEN, Germany. ConclusionIn the present study, we have successfully extracted and amplified DNA from old skeletal remains by using modified phenol chloroform method and DNA investigation Kit – QIAGEN, Germany, nevertheless the preservation of DNA in skeletal remains in Sri Lanka is very low.

Published: February 2020

IntroductionBased on historical records suggesting that the ancestry of the Purana (old) population living in the suburbs of Sigiriya in Sri Lanka can be traced back to the times of the Sinhalese Kings of the 5th century A.D. (1,450 YBP) and studies reporting that the Purana are biometrically different from the rest of present Sri Lankans and other populations in the world, we investigate the maternally inherited Mitochondrial DNA (mtDNA) of Purana population in the suburbs of Sigiriya to better understand genetic affinities of them to present day Sri Lankans. Materials and MethodsForty six Purana inhabitants belonging to Purana pedigrees were recruited in the study. Mitochondrial DNA was extracted, amplified and sequenced. Polymorphisms of mtDNA hypervariable segment I (HVS –I) between nucleotide positions 16,004 –16,411 were identified using CLUSTALX option of MEGAVA 4.0 sequence alignment software. In order to investigate genetic affinity of Purana population, Arlequin software version 3.11 and analysis of molecular variance (AMOVA) were applied using reported similar genetic data of present Sri Lankans such as Sinhalese, Sri Lankan Tamils, Indian Tamils, Sri Lankan Moors and Vedda. Genetic relationships of Purana population with other Sri Lankans were further explored by phylogenetic analysis. Results and AnalysisGenetic dissimilarity among groups was higher (2.81%) when populations were grouped into two as modern and Purana than grouping them according to their ethnic basis (0.00%). This indicates a restricted mtDNA flow between the two groups (Purana and rest of the Sri Lankans) that made Purana population was maternally isolated from the rest of Sri Lankans. ConclusionDetailed phylogenetic analysis of the study revealed that they are maternally more related to Sri Lankan Tamil than to any other present Sri Lankans.
