Published: December 2018

Toxoplasma gondii is of great concern in public health because it affects a lot of people in the globe. However, in the clinical setting, it rarely causes serious disease. The currents research was performed on university students in Basra province to estimate the prevalence of toxoplasmosis and its risk factors. It is first the time research was done in Basra province. Venous samples of blood were obtained from 177 women in the higher institution of learning of Basra in 2018. The participants were aged between nineteen to twenty-four years. The samples were analyzed if they had anti-T. gondii IgM & IgG antibodies that would show evidence of T.gondii infection. The participants were also given questionnaires to determine risk factors. The mean age of the participants was 21.24 years, and a majority of them were aged between twenty-two to twenty-four years. The differences between contact with an animal and age that has examined positive for toxoplasmosis were not statistically significant. Among the 177 participants only two, who are about 1.13% tested positive for T. gondii IgM which is consider as recent infection while, 20 of them with positive IgG antibodies was detect as a past infection. The only variable that had a positive association with testing positive to T. gondii was contacting with soil (garden at the house) the level of significance for the association was less than 0.05.

Published: December 2018

The present study, report the phytochemical analysis and in vitro antimalarial activity of plants Acalypha indica (L.) and Cocculus hirsutus (L.). The A. indica and C. hirsutus plant was collected from Kadaparajupalle at Dornala mandal, Prakasam district, Andhra Pradesh, India. Leaf, stem bark and root crude extracts prepared in Soxhlet apparatus with chloroform, ethyl acetate and methanol solvents. The preliminary phytochemical screening of these extracts was conducted by following the standard methods. These extracts were tested for in vitro antimalarial activity against 3D7 and K1 strains of Plasmodium falciparum by standard laboratory protocol. In vitro cytotoxicity of the extracts was also tested by following standard laboratory method. The phytochemical screening has revealed the presence of alkaloids, saponins, terpenoids & steroids, tannins, anthocyanidins, phenolic compounds, coumarins, quinones, resins and glycosides. Amongst all the extracts screened for antimalarial activity, the leaf chloroform and ethyl acetate extracts of A. indica shown IC50 values of 3.34 µg/mL and 3.71 µg/mL respectively against 3D7 strain; the leaf chloroform and ethyl acetate extracts of A. indica shown IC50 values of 1.47 µg/mL and 2.32 µg/mL respectively against K1 strain; the root chloroform and methanol extracts of C. hirsutus shown IC50 values of <0.78 µg/mL and 3.714 µg/mL respectively against 3D7 strain; the root chloroform and methanol extracts of C. hirsutus shown IC50 values of <0.78 µg/mL and 2.10 µg/mL respectively against K1 strain. Thus, the above extracts have shown very active antimalarial activity against 3D7 and K1 strains. And all the extracts were non-toxic showing CC50 values of >20 µg/mL against Vero cell line. The presence of high alkaloids, flavonoids and terpenoids of the plant extracts suggest their antioxidant potential and justifies their therapeutic action which could be used for the drug formulation. The chloroform root extract of C. hirsutus has shown excellent antimalarial activity which can be used for the development of new antimalarial drug policies.

Authors: Santosa Kadek Budi , WisnuTirtayasa Pande Made , Gde Oka AnakAgung
Published: December 2018

Female urethral stricture is uncommon and difficult to diagnose. Currently, only a small amount of literature has reported the successful treatment of female urethral stricture using a reconstruction approach. In this study we describe our results with the management of female urethral stricture using a dorsal vaginal graft. Four patients were diagnosed with female urethral stricture and were treated with urethral reconstruction using a dorsal vaginal graft. Primary urethroplasty using dorsal vaginal graft can be considered as a first-line option in the management of female urethral stricture, especially in centers with experience in graft-based reconstruction.

The variations in blood vessels are common and have long received the attention of anatomists and surgeons. The true pelvic cavity usually refers to that part of pelvis, which has its bony walls, the sacrum and lower part of hip bone. This small area is well covered by bones and has important structures namely the pelvic viscera, pelvic floor muscles, vessels and nerves supplying it. The aim of the study was to know the branching pattern of internal iliac artery based on the Adachis classification, along with length and thickness of artery. The internal iliac artery was traced from its origin, course, branching pattern, length and thickness of the trunk of internal iliac artery was measured by using digital vernier calliper from its point of origin to bifurcation into anterior and posterior division. The length of right & left internal iliac artery ranged from 2.4 cm to 5.4 cm with average length of 3.943cm ± 0.859cm, whereas the length of left internal iliac artery ranged from 2.7cm to 4.7cm with average length of 3.610cm ± 0.626cm. Bilateral ligation of internal iliac artery is helpful in controlling postpartum haemorrhage. Applying ligatures on an anomalous blood vessel may lead to alarming haemorrhage. The most ideal point of ligation of internal iliac artery would be distal to its posterior division, since proximal ligation has been associated with buttock claudication and necrosis. Knowledge regarding the internal iliac artery and its branches is helpful in applying ligatures safely during pelvic surgeries.

Published: December 2018

Osteoporosis is identifying based on the bone mineral density (BMD). The bone mineral mass or BMD exposes the amount of minerals present in a particular region of bone tissue. BMD measurement by DEXA is consideredas gold standard, but it is very expensive. The people of developing countriesare not interested to check BMD until the occurrence offracture. Therefore present study focusing any association of routine biochemical markers with BMD in osteoporosis and also planning to identify disease distribution status in south India. We examined 773 participants BMD by DEXA scan and grouped into three, Group I (Normal bone mass, n=237), group II (Osteopenia, n=345) and group III (Osteoporosis, n=191). The serum calcium, phosphorous and alkaline phosphatase (ALP) were estimated by automated chemistry analyzer., and Serum 25(OH) vitamin D was analyzed by immunoassay system analyser. The prevalence of normal BMD, osteopenia and osteoporosis was 30.7%, 44.6%and 24.7% respectively.Between 60 and 69 years aged men having more prevalence of osteopenia and in women 50 to 59 years of age. While osteoporosis in men 50 to 59 years and in women’s were 60 to 69 years of age. The serum calcium, ALP and 25 (OH) vitamin D levels were statistically significant (p< 0.001) between the three groups.The higher percentage of low bone mineral density (osteopenia) is the alarming signalto the bone health and this could be continued leads to osteoporosis, which affects the quality of life. This study suggests to determining BMD along with biochemical markers are useful to identify osteoporosis in earlier stage. Therefore routine screening of BMD may prevent the risk of osteoporosis.

Maternal preconceiving nutrition is thought to affect fertility outcomes. The current emphasis on the omega-3 fatty acids, which has been associated with improved fertility in both spontaneous and assisted reproduction conceptions. This study aims to evaluate the role of preconceiving omega 3 polyunsaturated fatty acids supplementation in enhancing the proportion between follicles and retrieved ova, the fertilization rate, and the embryonic grading in subfertile females experiencing intracytoplasmic sperm injection management protocols. One-hundred twenty subfertile women aged 20-40 years-old undergoing intra-cytoplasmic sperm injection were recruited in this randomized double-blinded placebo-controlled clinical trial, at Fertility Center/ Al-Sadr Teaching Hospital/ Al Najaf/ Iraq. They were randomly assigned into two groups; group A (omega-3) includes 60 subfertile women who received one capsule 1000mg omega-3 and Group B (placebo) includes 60 subfertile women who received a placebo contain Liquid Paraffin 500mg for eight weeks. The number of follicles, number of oocytes, fertilization rates, and embryonic quality were recorded in both groups. The study result revealed that the ratio of follicle/retrieved oocyte, the number of metaphase II oocytes, fertilization rate, and grade I embryo were more in the group A compared to group B. Supplementation with Omega-3 polyunsaturated fatty acids can increase the ratio of follicle/retrieved oocyte, the number of metaphase II oocytes, fertilization rate, and grade I embryo, and thereby improving the pregnancy outcome in intracytoplasmic sperm injection cycles.

The HOX genes are transcription factors that are expressed in coordinated spatiotemporal patterns to ensure normal development. Ectopic expression may instead lead to the development and progression of tumors. Genetic polymorphisms in the regions of four HOX gene clusters were tested for association with lung cancer in 420 cases and 3,151 controls. The effect of these variants on lung gene expression (expression quantitative trait loci, eQTL) was tested in a discovery set of 409 non-tumor lung samples and validated in two lung eQTL replication sets (n = 287 and 342). The expression levels of HOXB2 were evaluated at the mRNA and protein levels by quantitative real-time PCR and immunohistochemistry in paired tumor and non-tumor lung tissue samples. The most significant SNP associated with lung cancer in the HOXB cluster was rs10853100 located upstream of the HOXB cluster. HOXB2 was the top eQTL-regulated gene with several polymorphisms associated with its mRNA expression levels in lung tissue. This includes the lung cancer SNP rs10853100 that was significantly associated with HOXB2 expression (P=3.39E-7). In the lung eQTL discovery and replication sets, the lung cancer risk allele (T) for rs10853100 was associated with lower HOXB2 expression levels. In paired normal-tumor samples, HOXB2 mRNA and protein levels were significantly reduced in tumors when compared to non-tumor lung tissues. Genetic variants in the HOXB cluster may confer susceptibility to lung cancer by modulating the expression of HOXB2 in the lung.
Contributions of 5’HoxA/D regulation to actinodin evolution and the fin-to-limb transition
Authors: Lalonde Robert L. , Akimenko Marie-Andrée
Published: December 2018

The evolution of tetrapod limbs from paired fish fins comprised major changes to the appendicular dermal and endochondral skeleton. Fish fin rays were lost, and the endochondral bone was modified and elaborated to form three distinct segments common to all tetrapod limbs: the stylopod, the zeugopod and the autopod. Identifying the molecular mechanisms that contributed to these morphological changes presents a unique insight into our own evolutionary history. This review first summarizes previously identified cis-acting regulatory elements for the 5’HoxA/D genes and actinodin1 that were tested using transgenic swap experiments between fish and tetrapods. Conserved regulatory networks provide evidence for a deep homology between distal fin structures and the autopod, while diverging regulatory strategies highlight potential molecular mechanisms that contributed to the fin-to-limb transition. Next, we summarize studies that performed functional analysis to recapitulate fish-tetrapod diverging regulatory strategies and then discuss their potential morphological consequences during limb evolution. Finally, we also discuss here some of the advantages and disadvantages of using zebrafish to study molecular and morphological changes during the fin-to-limb transition.
Regulatory landscape of the Hox transcriptome
Authors: Casaca Ana , Hauswirth Gabriel M. , Bildsoe Heidi , Mallo Moisés , McGlinn Edwina
Published: December 2018

Precise regulation of Hox gene activity is essential to achieve proper control of animal embryonic development and to avoid generation of a variety of malignancies. This is a multilayered process, including complex polycistronic transcription, RNA processing, microRNA repression, long noncoding RNA regulation and sequence-specific translational control, acting together to achieve robust quantitative and qualitative Hox protein output. For many such mechanisms, the Hox cluster gene network has turned out to serve as a paradigmatic model for their study. In this review, we discuss current knowledge of how the different layers of post-transcriptional regulation and the production of a variety of noncoding RNA species control Hox output, and how this shapes formation of developmental systems that are reproducibly patterned by complex Hox networks.
Hox genes in the pharyngeal region: how Hoxa3 controls early embryonic development of the pharyngeal organs
Authors: Gordon Julie
Published: December 2018

The pharyngeal organs, namely the thyroid, thymus, parathyroids, and ultimobranchial bodies, derive from the pharyngeal endoderm during embryonic development. The pharyngeal region is a segmented structure comprised of a series of reiterated structures: the pharyngeal arches on the exterior surface, the pharyngeal pouches on the interior, and a mesenchymal core. It is well known that Hox genes control spatial identity along the anterior-posterior axis of the developing vertebrate embryo, and nowhere is this is more evident than in the pharyngeal region. Each of the distinct segmented regions has a unique pattern of Hox expression, which conveys crucial positional information to the cells and tissues within it. In the context of pharyngeal organ development, molecular data suggest that HOXA3 is responsible for specifying organ identity within the third pharyngeal pouch, and in its absence, thymus and parathyroid organogenesis fails to proceed normally. Recent studies comprising a series of Hoxa3 mutations identified specific spatial and temporal roles for HOXA3 in pharyngeal organ development, including both cell-autonomous and non-autonomous functions, revealing a system that is more complex than originally thought. Here, we will review the current understanding of the role of Hox genes in the early embryonic development of the pharyngeal organs in the mouse, with a particular focus on the function of HOXA3 in thymus and parathyroid organogenesis.

Les importations de bois de Brésil en Normandie dans la première moitié du XVIe siècle
Authors: Maneuvrier Christophe , Daeffler Michel , Bretthauer Isabelle
Published: December 2018

La découverte de nouveaux documents issus d’archives judiciaires permet de mieux appréhender l’organisation des voyages des ports normands vers le Brésil. Les départs avaient généralement lieu à l’automne ou au début de l’hiver, les retours s’effectuant durant l’été. Pour réduire les risques et échapper auxflottes portugaises, les navires voyageaient en convois, souvent de trois à cinq navires dont les caractéristiques peuvent être présentées grâce à plusieurs contrats de construction conservés dans des registres notariés. La mise en oeuvre de ces expéditions nécessitait d’importants capitaux rassemblés par desmarchands rouennais. Parmi eux, figurent plusieurs familles d’origine espagnole de niveau international qui pouvaient parfois s’associer avec des investisseurs de Paris, de Lyon, ou de Champagne. Les quantités de bois‑brésil rapportées en Normandie étaient considérables. Une partie de ces marchandises fut très tôt réexpédiée à Paris, la Rochelle et jusqu’à Anvers, Rouen étant alors un entrepôt international de tout premier ordre. Le bois‑brésilétait utilisé comme produit tinctorial mais aussi dans l’architecture, notamment au château de Fontainebleau (demeure favorite de François Ier), ainsi que dans la fabrication de meubles ou de petits objets de luxe. Ces sources nouvelles montrent enfin que les expéditions des frères Verrazzano n’ont pas ouvert la route du Brésil aux marchands français, mais que ces échanges ont commencé beaucoup plus tôt, même si une accélération de ce trafic est probable au cours de la décennie 1520.
Le sale cinematografiche nello scenario moderno dell’architettura portoghese della prima metà del XX secolo : alcuni esempi a confronto
Authors: Licordari Mariangela
Published: December 2018

Vero e proprio fenomeno culturale del XX secolo, in ambito architettonico il cinema rappresenta da sempre il simbolo della modernità e del progresso tecnologico. Nella storia dell’architettura moderna, la progettazione delle sale cinematografiche va di pari passo con la sperimentazione di nuove forme architettoniche rese possibili dall’impiego di moderni materiali da costruzione (quali in primis il cemento armato), divenendo un importante banco di prova tanto per la verifica tecnologica degli stessi quanto per l’immaginazione spaziale di nuovi ambienti, così divergenti da quelli propriamente classici dei teatri. Spazio architettonico fruibile e funzionale al vissuto umano, il cinema diventa rapidamente espressione di crescita, di sviluppo sociale ed economico e di prestigio urbanistico. Anche in Portogallo, come nel resto dell’Europa, le sale cinematografiche sono segnali tangibili del cambiamento stilistico e formale dell’architettura della prima metà del Novecento, facendosi portavoce di un’immagine nuova che rapidamente adornerà le città portoghesi d’un aspetto moderno e scenografico al tempo stesso.

Grupos sociais da Beira Interior em meados do século XIX
Authors: Nunes João
Published: December 2018

No planalto beirão, região grosso modo confinada pela serra da Lapa e o rio Mondego, a distribuição da população por grupos sociais não era homogénea, em meados do século XIX. Havia localidades onde a categoria jornaleiro era a mais representativa, em contraponto com outras onde as categorias lavrador ou seareiro acabavam por ser as mais expressivas. O direito liberal parece não ter contribuído para a proliferação de indivíduos pertencentes à categoria proprietários. Com efeito, o aumento foi mais visível noutras categorias sociais.

Género e receção mediática no Estado Novo
Authors: Carvalheiro Ricardo , Silveirinha Maria João
Published: December 2018

Baseado em testemunhos femininos relativos ao período entre as décadas de 1940 e 1960, este texto procura dar um contributo para a compreensão da forma como a receção mediática por parte das mulheres portuguesas foi obrigada a encontrar o seu espaço de articulação com a vida quotidiana no interior do contexto constrangedor e da cultura patriarcal no Portugal do Estado Novo, nos termos da sua hegemonia moral e das rígidas fronteiras que impunha aos papéis de género. Através de entrevistas biográficas com mulheres nascidas nas primeiras décadas do regime salazarista, abordamos alguns modos de receção da rádio e da televisão na medida em que eles configuravam uma adaptação dos então ‘novos media’ a regimes censórios profundamente interiorizados no que respeita a comportamentos e relações de género.

Ativismo feminista no Facebook: uma análise comparada das páginas Não me Kahlo (Brasil) e Capazes (Portugal)
Authors: Magalhães Mara , Marôpo Lidia , Amaral Inês
Published: December 2018

Levando em consideração o feminismo como movimento social e ativismo digital, analisamos comparativamente as páginas feministas brasileira e portuguesa com maior número de seguidores no Facebook, respectivamente Não me Kahlo e Capazes. Neste estudo exploratório, utilizámos a ferramenta Netvizz para mapear os conteúdos publicados em março de 2016, numa análise quanti‑qualitativa. Os resultados sublinham semelhanças nas temáticas abordadas que apontam para um enlace identitário (Pereira, 2011) entre os dois perfis, mas também diferentes ‘nós’ feministas (Tomazetti, 2015) em função das características de cada página e do contexto dos países. Na página portuguesa prevalecem narrativas individuais e pessoais, num tom intimista e confessional, com posições político‑partidárias pouco explícitas, num feminismo em primeira pessoa, próximo ao que Galloway (1997) chama de ciberfeminismo conservador. Na página brasileira, os discursos são fortemente politizados, em tons reativos, reivindicativos ou de denúncias, que remetem para o feminismo como causa coletiva, no que Boix e Miguel (2013) chamam de ciberfeminismo social.
Dois corpos objetificados: igualdade nas representações publicitárias?
Authors: Figueiredo Ana Filipa Da Fonseca , Pacheco Daniela Filipa De Abreu
Published: December 2018

Inerentes às construções sociais de sexo e género estão assimetrias de poder históricas, que por sua vez podem ser veiculadas pela publicidade. Neste artigo,pretendemos analisar e refletir sobre as práticas representacionais publicitárias contemporâneas e as suas possíveis contribuições para a manutenção das desigualdades sociais entre os géneros. Através de revisão de literatura e de um estudo de caso comparativo pretendemos responder a duas questões: a primeira é se tanto os corpos femininos como os masculinos foram objetificados e sexualizados nas representações publicitárias; e a segunda é se estas representações veiculam estereótipos de género em simetria de poder. Conclui‑se que não obstante a tímida e ultra recente igualdade no que concerne àobjetificação dos corpos, a representação de feminilidade e masculinidade está ainda assente em idealizações arcaicas que são mantidas nas culturas visuais e que têm um impacto determinante na vida real dos homens e das mulheres, continuando a contribuir para um desequilíbrio social entre os indivíduos.
Desconstruções do feminino: uma leitura das postagens de mães de crianças autistas no Facebook
Authors: Biondi Angie , Ries Igor Lucas
Published: December 2018

O rótulo mãe azul é usado como homenagem às mulheres que cuidam de filhos com transtorno autista. Porém, ao mesmo tempo que posiciona a mulher no papel de cuidadora, o rótulo também lhe designa o lugar da abnegação e sacrifício pela dedicação à maternidade exemplar. Fixadas no papel de mãe ideal, as mulheres ainda são classificadas como sujeitos reconhecíveis e aceitáveis socialmente pela correspondência aos valores morais ancorados no cuidado da prole. Este texto apresenta parte do estudo de caso realizado na pesquisa sobre as práticas enunciativas e comunicacionais em postagens divulgadas por mães de crianças portadoras do autismo, através da página Lagarta Vira Pupa, no Facebook, entre janeiro e julho de 2017. A análise, baseada na etnografia virtual, observa como as mulheres elaboram sua fala voltada à promoção da autonomia e autoafirmação, a fim de romper com a identidade feminina fixada na maternidade ideal, incompatível com a experiência cotidiana.
Effect of insulin or insulin-like growth factor-I administration at mid-luteal phase of the estrous cycle during superovulation on hormonal profile of Sahiwal cows
Authors: Sheetal S. K. , Prasad Shiv , Gupta H. P.
Published: December 2018

Aim: The present study was designed to study the effect of insulin and insulin-like growth factor-1 (IGF-I) administration during luteal phase of the estrous cycle on the hormonal profile of Sahiwal embryo donor cows during superovulation.

Materials and Methods: Cows (n=18) were selected and divided into three groups; control (n=6, untreated), T-I (n=6, insulin-treated), and T-II (n=6, IGF-I treated). Insulin and IGF-I were given S/C on 5th, 6th, 7th, and 8th days of estrous cycle. Superovulatory treatment was started on day 9th of the estrous cycle. With the sixth dose of follicle-stimulating hormone, prostaglandin was injected to induce superovulatory heat. The superovulated cows were bred, and superovulatory response of each animal was recorded. The embryos were collected non-surgically on the 7th day of superovulatory estrus. About 15 ml blood without anticoagulant was collected on days 5, 7, 9, 11, 13, 15, 17, 19, and 21 or day of embryo recovery where day 0 of estrous cycle was taken as day of estrus. Serum was separated, centrifuged, and transferred into sterilized serum vials. All samples were stored at -20°C till analysis. Progesterone, insulin, and IGF-I were estimated in blood serum by radioimmunoassay using radioimmunoassay kits.

Results and discussion: The mean concentration of progesterone on days 7 and 11, insulin on days 7 and 9, and IGF-I on days 5, 7, 9, 11, and 15 was significantly higher in insulin-treated T-I groups as compared to untreated control.

Conclusions: It may be concluded that exogenous insulin administration during mid-luteal phase may be helpful in follicular and embryonic development through modulation of progesterone, insulin, and IGF-I in indigenous (Bos indicus) Sahiwal embryo donor cows.
Internal Innovation Capacity and External Linkages in Firms of ASEAN Economies Focusing on Endogeneity
Authors: Ogawa Masamaru , Ueki Yasuhi , Idota Hiroki , Bunno Teruyuki , Tsuji Masatsugu
Published: December 2018

Based on survey data of firms in four ASEAN economies, this paper examines the role of internal innovation capacity which includes technological level, organizational learning, and human resources on innovation. To make this concept more tractable for statistical analysis, an index of internal capacity using AHP (Analytical Hierarchy Process) was constructed. By using this index, this paper attempts to examine how the internal capacity of firms is enhanced by external linkages such as MNCs (Multinational Corporations), universities, and public organizations. In particular, this study analyzes the endogeneity problem, which clarifies the causality between innovation and factors to promote it. In so doing, the instrumental variable method was employed, and as a result, external linkages enhanced internal innovation capacity, and internal innovation capability promotes innovation, while external linkages indirectly enhance innovation.  

 

Key Words- Internal capacity, absorptive capacity, AHP, causality, endogeneity, probit analysis

The process of removal aluminum and cobalt ions from aqueous solutions with a phosphorus-containing product containing inositol hexaphosphoric acid derivatives obtained from rice production wastes of Far Eastern selection varieties – rice flour, and optimal conditions were determined. It is established that the efficiency of removal of metal cations by the phosphorus-containing product depends not only on their nature, but also on the initial concentration of ions in solutions. The degree of extraction of aluminum ions reaches 99%, and cobalt – 76%. The principal possibility of using phosphorus-containing products of plant origin in the development of environmentally safe materials for the removal of metal ions in technologies requiring the use of green chemistry methodology is proposed.

The influence of geoecological factors formed in Velsk-Ustyansk tectonic node of the Arkhangelsk region on the state of lichenobiotics was studied. Two of the most common species of bushy lichens are selected as the test systems. The objects of research are two species of bushy lichens, which were used as a test system. From the soil lichens, the species Cladonia stellaris was studied. From the epiphytic lichens, the species Usnea subfloridana was studied. The material was collected in the vegetation period (spring-autumn) from the three test plots (in the center, at the periphery and outside the tectonic node - the background point) in the pine-bilberry forest stands with the same composition.It was established that the ash content of lichen samples Cladonia stellaris and Usnea subfloridana increases in the direction from the background point and further from the periphery to the center of the node. The ash content for samples growing in the center of the tectonic node is in 2-7 times higher than in the background point and reaches of 7 %. The ash content for samples growing in the periphery of the site is in 1.5–2 times higher than in the background point. This dependence indicates a significant accumulation of the metals in the lichen thallomes in the zone of tectonic faults. The similar dependence for both lichens is observed in the content of ascorbic acid, catalase activity and antioxidant activity. It was shown that in the center of the node the lichen contains up to 190 μg·g-1 of ascorbic acid, the catalase activity is up to 17 u.o.d. g-1·s-1, and antioxidant activity is up to 53%, while at the background point these indices do not exceed 130 μg·g-1 , 7 u.o.d. g-1·s-1 and 35%, respectively. Thus, it can be concluded that under stress condition there is a free-radical oxidation that can regarded as a marker of development of a non-specific stable in lichens under the influence of various stressors.

Hairy root cultures are being considered as promising system for producing valuable second metabolites. These genetically transformed root cultures are characterized by high growth rate, genetic stability and growth in hormone free media. Using A. rhizogenes-mediated transformation method (strain А-4), we have obtained hairy root cultures of the ecdysteroid-containing species of Silene linicola. HPLC analysis of the sample studied revealed that 20-hydroxyecdysone (20E), turkesterone and polypodin B were synthesized under the specified experimental conditions. Application of methyl jasmonate at a concentration of 100 μM resulted in stimulation of 20E biosynthesis (up 74%) after 3 days of cultivation and turkesterone up to 35% at 6 days.  It was noted that total ecdysteroid content in sample tested varied: turkesterone from 25 to 60%, and 20E from 8 to 30%. At the same time the level of 20E biosynthesis decreased from 0.023 to 0.014% in the samples without methyl jasmonate treatment. Hairy root lines of S. linicola with different responses to the presence of elicitors in the culture medium can be used to study the pathways of ecdysteroid biosynthesis.

The dynamic dependencies of the dynamic shear modulus and the loss modulus of Quercus Robur L. oak wood, subjected to pretreatment by explosive autohydrolysis, were obtained by dynamic mechanical analysis. It is shown that, as a result of an increase in the degree of hydrolysis stiffness, the glass transition temperature of the complex of amorphous wood components decreases. The maximum decrease in the glass transition temperature in comparison with the initial wood, determined from the positions of the minimum temperature derivative of the dynamic shear modulus and the peak at the temperature dependence of the dynamic loss modulus, is 75 °C and 45 °C, respectively. With increasing rigidity of the conditions of barothermal processing, the value of the dynamic shear modulus tends to decrease at room temperature. It was found that the temperatures of the maxima position on the temperature dependences of the dynamic loss modulus do not correspond to the temperatures of the minima on the temperature derivative, and with the increase in the degree of hydrolysis stiffness this discrepancy is significantly increased. Assumptions are made about the nature of the processes occurring in the wood tissue and causing these effects. It is most likely that the decrease in the glass transition temperature of the amorphous component in the samples of the hydrolyzed wood substance compared to the original wood is a consequence of the increase in the flexibility of the molecular chains of the lignocarbon complex. Reducing substances and fragments of low molecular weight lignin, formed during hydrolysis, act as a plasticizer and facilitate the mobility of the kinetic components of the wood substance.

The known methods to obtain microcrystalline cellulose (MCC) from wood raw material is multi-stage and it is based on the integration of environmentally hazardous processes of pulping, bleaching and acid hydrolysis of cellulose amorphous part. The paper describes a one-stage catalytic method to obtain microcrystalline cellulose from pine wood based on peroxide delignification in acetic acid-water in the presence of a catalyst H2SO4. The optimal parameters of the process of pine wood peroxide delignification in the presence of 2% H2SO4 catalyst were determined by experimental and numerical methods: temperature – 100 °C, concentration H2O2 – 5 wt.%, CH3COOH – 25 wt.%, LWR 15, duration – 4 h. They provide a high yield of cellulose (45.2 wt.%) with a low content of residual lignin (1.0 wt%).The kinetic study of pine wood peroxide delignification at the temperature range 70-100 ºC was accomplished. The delignification process is described satisfactory by the first order equation in all temperature range. The rate constants vary between 0.08·10-4 and 2.15·10-4 s-1 and the activation energy is 90 kJmol-1. It was established by FTIR and XRD methods, that the cellulose, obtained from pine wood has the composition and structure similar to the commercial microcrystalline cellulose.

Projetar cadeia de suprimentos é uma importante decisão estratégica e seu impacto influencia diretamente na eficiência e no nível de serviço. O projeto se torna mais complexo quando o objetivo é minimizar o custo de distribuição e utilizar a postergação de tempo na cadeia de suprimentos. Os modelos matemáticos atualmente estudados na literatura de cadeia de suprimentos consideram vários atores. Entretanto, em problemas reais existem diferentes combinações desses atores, criando fluxos próprios de transportes e aumentando a complexidade da cadeia de suprimentos. Este artigo propõe um modelo matemático para projetar a cadeia de suprimentos com postergação de tempo a partir da programação não linear inteira mista para minimizar o custo total, considerando os custos de transportes, abertura de instalações e operacionais. O modelo permite a possibilidade de uma instalação híbrida, ou seja, dois tipos de instalações abertas no mesmo local, sendo uma importante oportunidade de redução de custos. Diferentes conjuntos de instâncias foram simulados para buscar a solução ótima e analisar o comportamento da cadeia de suprimentos em diferentes tamanhos de cenários, os quais foram resolvidos usando um solver comercial e suas performances foram estudadas. O modelo proposto apresenta viabilidade em seu uso para instâncias pequenas e médias com tempo computacional suficiente para auxílio no processo de tomada de decisão.

O módulo dinâmico |E*| é a propriedade de rigidez de misturas asfálticas mais utilizada como parâmetro de entrada no dimensionamento mecanístico-empírico de estruturas de pavimentos asfálticos. Apesar de bem estabelecido internacionalmente, ainda não há, no Brasil, normatização de ensaio para sua determinação, e ele não é considerado no método vigente de dimensionamento. Embora as metodologias de ensaio sejam bem consolidadas internacionalmente, diversos modelos de previsão de |E*| são reportados na literatura internacional, objetivando reduzir tempo e custos de sua obtenção experimental. No presente estudo, foram avaliados modelos de previsão de módulo dinâmico da literatura internacional, com dados de ensaios laboratoriais de 24 misturas asfálticas nacionais. Avaliados os modelos existentes, foi proposta a calibração daquele que se mostrou mais eficiente, resultando em uma equação simplificada e bem ajustada aos dados analisados. Espera-se que modelos calibrados como o aqui proposto possam ser facilitadores da aplicação, no Brasil, de métodos mecanístico-empíricos de dimensionamento de pavimentos. Esses métodos possibilitam considerar o comportamento viscoelástico dos materiais asfálticos, ou seja, levar em conta os efeitos da temperatura e da velocidade dos veículos no projeto de pavimentos.

O presente artigo tem como objetivo subsidiar o desenvolvimento de um modelo matemático de demanda de viagens de bicicletas em vias urbanas. Assim, apresenta-se uma revisão bibliográfica dos modelos de demanda de viagens por bicicleta e busca-se um modelo de demanda direta mediante regressão linear múltipla com base em contagens volumétricas realizadas na zona sul da cidade de Rio de Janeiro. A partir deste processo, foi possível elencar as principais variáveis que influenciam na demanda deste tipo de viagem, bem como sua significância e carácter do sinal delas nos modelos. Para vias com disponibilidade de infraestrutura para circulação de bicicletas, a presença de estacionamento, a temperatura máxima da região e o número de acidentes de trânsito são os fatores que mais influenciam o uso da bicicleta. Para vias sem infraestrutura, os principais fatores são: número de interseções, proximidade a vias cicláveis e número de faixas. Finalmente, foi possível identificar um modelo de demanda direta para viagens em vias com infraestrutura para circulação de bicicletas.
