On Mp-embedded primary subgroups of finite groups
Authors: Zhang Jia , Miao Long
Published: November 2016

A subgroup H of G is called Mp-embedded in G, if there exists a p-nilpotent subgroup B of G such that Hp ∈ Sylp(B) and B is Mp-supplemented in G. In this paper, we use Mp-embedded subgroups to study the structure of finite groups.
Extended arcsine distribution to proportional data: Properties and applications
Authors: Cordeiro Gauss M. , Lemonte Artur J. , Campelo Ana K.
Published: November 2016

We propose a new two-parameter continuous model called the extended arcsine distribution restricted to the unit interval. It is a very competitive model to the beta and Kumaraswamy distributions for modeling percentages, rates, fractions and proportions. We provide a mathematical treatment of the new distribution including explicit expressions for the ordinary and incomplete moments, mean deviations, Bonferroni and Lorenz curves, generating and quantile functions, Shannon entropy and order statistics. Maximum likelihood is used to estimate the model parameters and the expected information matrix is determined. We demonstrate by means of two applications to proportional data that it can give consistently a better fit than other important statistical models.

Published: November 2016

In this paper, we study dissipative q-Sturm—Liouville operators in Weyl’s limit circle case. We describe all maximal dissipative, maximal accretive, self adjoint extensions of q-Sturm—Liouville operators. Using Livšic’s theorems, we prove a theorem on completeness of the system of eigenvectors and associated vectors of the dissipative q-Sturm—Liouville operators.

New analyses on some Kalbak-Tash inscriptions
Authors: Yildiz Hülya
Published: November 2016

This paper focuses on Kalbak-Tash Inscriptions Nos XX, XXI and XXII which belong to the group of the Mountainous Altai Inscriptions. It provides an analysis of the problematic issues of these three inscriptions having emerged in previous studies, as well as to some new reading proposals for some parts of the inscriptions. The words kara and égil in Inscription No. XXI are interpreted as “commoner, an ordinary person”; and the word igen “deer” (< Old Turkic ingen “she-camel”) in Inscriptions No. XX and No. XXI is explained with the correspondence of Old Turkic teve “camel” = Yakut taba “reindeer”. In addition, the study lays emphasis on the fact that the antepenultimate sign of Inscription No. XXII could be s1, and the word asŋar- which includes this sign could be interpreted as “(he) stopped (work) on the affair and sat down”. Another proposal which is put forward for Inscription No. XXII is that the signs g2t2r2 are explained as éget er “servant, retainer”.
On some oriental elements in Old Novgorodian and other Old Russian dialects

Published: November 2016

The author is aiming to interpret the historical connection between Old Russian kamka and Old Novgorodian õàìú ‘textile of silk damask’. She comes to the conclusion that the former is a borrowing from East Old Turkic qamqï, while the latter is a loan from West Old Turkic χamï. Both Old Turkic words are of Chinese origin.
Shoes in Buddhist monasteries from India to China: From practical attire to symbol
Authors: Heirman Ann
Published: November 2016

One of the most visible identity markers of Buddhist monasticism is clothing. The robes of monks and nuns have been paid considerable attention by researchers. By contrast, other pieces of monastic clothing have attracted far less attention, and this is particularly the case with footwear. Although shoes certainly play a secondary role compared to robes, they still present the monastic community with a number of complex issues. Shoes touch the ground, so they inevitably get dirty. Hence, wearing shoes could be considered disrespectful when meeting someone or paying homage, but so could showing one’s naked feet. Meanwhile, shoes protect the feet from dirt and injury on difficult roads, so they may be viewed as essential attire. Additional issues relate to the material and the shape of the footwear, and which shoes are the most appropriate in various situations. This study discusses early Buddhist disciplinary (vinaya) texts’ guidelines on issues relating to footwear, and explores how these guidelines were later received within China. It also provides a detailed picture of early Indian and Chinese Buddhist communities’ attitudes to shoes, a problematic element of monastic clothing.
L’acte de lecture comme proposé par Ibn Al-Muqaffaʿ
Authors: Mahassine Mohamed
Published: November 2016

Pour Ibn al-Muqaffaʿ (ca. 106/724 – 142/759) l’acte d’écrire dépasse le souci de considérer l’écriture comme un acte, à celui d’un homme engagé pour qui « l’écriture devient comme une signature, une institution qui découvre son passé et ses choix, lui donne une histoire, affiche sa situation et l’engage sans qu’il ait à le dire. Ce qui peut évidemment nous renvoyer à la position d’al-adīb. Privé du pouvoir politique et de la force matérielle, il use du seul pouvoir dont il dispose : le pouvoir du langage verbal écrit. Craignant la déviation du lecteur de la visée de l’écrivain Ibn al-Muqaffaʿ a pris le soin de tracer un processus de lecture régit par des règles visant à orienter l’acte de lecture, se qui a mené à l’élaboration d’une théorie de la lecture fondée sur la conscience précoce de différents genres de lectures, de différents types de lecteurs possibles et de différentes formes d’interprétation du texte écrit; le tout nourrit par le souci de préserver le sens de l’écriture et d’assurer la pérennité de l’oeuvre écrite à travers le temps. Le résultat est la production d’un texte (Kalila wa Dimna) doté d’un double pouvoir au moyen duquel l’écriture a réussi à préserver et à conserver le sens que représente son aspect apparent, comme il peut produire un sens nouveau.

Authors: Wongprom Prasit , Košulič Ondřej
Published: November 2016

Faunistic records of spiders in dry dipterocarp forests of Thailand are presented. Spiders were surveyed from November 2008 to December 2012. A total of 1,926 spider individuals were collected from 16 locations by visually searching, sweeping grasses and herb vegetation, beating shrubs and trees, and shifting leaf litters. Spiders were identified to 106 species in 86 genera of 29 families. The families Araneidae, Salticidae, Thomisidae, Tetragnathidae, and Theridiidae exhibited higher species richness. Several families that are rare and poorly known in Thailand were recorded, such as Stenochilidae, Eresidae, Idiopidae, Theraphosidae, and Nemesiidae. A faunistic overview of the spiders found in dry dipterocarp forest is presented. In general, the diverse composition of spiders and their guilds and the occurrence of rare and poorly known species in the Thai region confirm the high biotic value of dry dipterocarp forests. Continuing to maintain dry dipterocarp forest functions should be considered in future studies.

Published: November 2016

The Floresta Nacional Mário Xavier (FNMX) is a reserve located in the Municipality of Seropédica, State of Rio de Janeiro, southeastern Brazil. It is an area with intense anthropic activity and is one of the last remaining forests of the Baixada Fluminense. An inventory of the anurans of the FNMX was performed and the results compared with those of a previous species list for the area. Thirteen excursions were conducted, totaling more than 416 hours of sampling effort. Twenty-six species belonging to five families were found: Bufonidae (one species), Hylidae (15 species), Leptodactylidae (six species), Microhylidae (three species) and Phyllomedusidae (one species). Six species on the previous list were not found in this study. Sphaenorhynchus planicola is a new record for the area. Two species are endangered: Chiasmocleis lacrimae and Physalaemus soaresi, the latter being considered critically endangered by the List of Brazilian Fauna Threatened with Extinction.
Progressive Islam and Women’s Religious Leadership: Analysing the Emergence of New Models of Shared Authority
Authors: Worthington Lisa
Published: November 2016

In response to radical interpretations of Islam numerous progressive Muslim movements have emerged in order to demonstrate that Islam can be both equitable and inclusive. This paper is focused on two progressive organisations: Muslims for Progressive Values and El-Tawhid Jumma Circle and their practice of shared authority. Shared authority necessitates that leadership responsibilities are shared among the congregation and that religious leadership positions are open to all. In practice this means that women can assume religious leadership roles. Using field work data, this article will examine the experiences of progressive Muslim women who take up leadership positions in new Islamic organisations. It will be argued that progressive Muslims are creating alternative shared authority structures within their congregations in order to construct egalitarian worship spaces and open religious leadership to women.
Creating Communities of Justice and Peace: Sacramentality and Public Catholicism in the United States
Authors: Carbine Rosemary P.
Published: November 2016

This essay situates women’s religious leadership in the contested site of who and what counts as the authoritative face and practice of public Catholicism. It examines political praxis by U.S. Catholic women religious as a refreshing resource for a constructive feminist theology of the public church. Drawing on Vatican II theologies about the church’s social role, feminist and womanist theologies of sacramentality, and the Nuns on the Bus tours between 2012 and 2014, this essay argues that the U.S. public church bears sacramental significance when it re/creates the public, when it prophetically witnesses to an alternative political reality or creates (or births) a new world that better signifies a more interconnected, interdependent U.S. body politic rooted in solidarity. Examining concurrent activism by U.S. nuns and US Catholic bishops’ shows that what makes the public church public consists in the ability to imagine and create communities of justice and peace.
‘This is the age of women’: Legitimizing Female Authority in Contemporary Turkish Sufism
Authors: Neubauer Anna
Published: November 2016

Although Sufism has generally shown a greater openness to women than other forms of Islam, women in position of power have been relatively rare in its history. It is often in the informal sphere, where authority is linked to sainthood and charisma, that female leadership developed. Drawing on the example of Cemalnur Sargut, a female spiritual guide who is the head of a branch of the Rif??iyya in Istanbul, this article examines the possibilities for women to gain access to spiritual leadership with male and female disciples in contemporary Sufism. Sargut’s originality lies in the fact that she claims a semi-formal authority for women. The paper analyses how Sargut and her predecessor, also a woman, have engaged in interpretations of the history of Sufism and of their own group to legitimize their authority.
Contested Feminisms: Women’s Religious Leadership and the Politics of Contemporary Western Feminism
Authors: McPhillips Kathleen
Published: November 2016

Feminism is a relatively recent social movement of radical reform, emerging from the mass political movements of democratisation, secularisation and liberalism that swept across the western world from the 17th century onwards. The first wave of organised feminist political action was articulated in the abolitionist, temperance and suffrage movements in America and Europe in the mid 19th century and culminated in the Seneca Falls Convention of 1848 in New York State where the women’s rights movement was born. Religion was a crucial influence in the work of first wave feminists enjoying close ties to the liberal movements of Protestantism, particularly the Quaker movement. However, as modernity progressed into the twentieth century and secularism became incorporated into statecraft, the influence of religion in the public sphere waned and humanist ethics came to the fore in political life. So, although Christianity had been a primary part of first wave feminism in the nineteenth and early twentieth centuries, from the 1960s second wave feminism embraced secularism and situated religion as an inherently patriarchal institution, incapable of social change and has yet to acknowledge the pivotal part that women’s religious leadership played in establishing the grounds for contemporary feminist politics. Recently, a third phase of religious feminism, defined as post-secular feminism, shifts the ground yet again to open up new possibilities of engagement between religious and non-religious feminisms. Following on from the first two waves of religious feminism, this third phase holds potential for counter hegemonic action in transforming gender conservative religious institutions, theologies and social practices towards more inclusive, potentially transformative, religious cultures. It also provides space for a new articulation of religious and secular feminist politics.
LAPAROSCOPIC CHOLECYSTECTOMY PERFORMED SIMULTANEOUSLY WITH RETROPERITONEOSCOPIC LIVING DONOR NEPHRECTOMY
Authors: Perlin D. V. , Aleksandrov I. V. , Zipunnikov V. P. , Dymkov I. N.
Published: November 2016

The shortage of donor organs leads to a gradual extension of the selection criteria for living donors including age and presence of comorbidities. Performing simultaneous operations with donor nephrectomy would further increase the number of living donors and increase the attractiveness of operations. In this observation, the examination of a 60-year-old potential donor revealed a concomitant disease: chronic calculous cholecystitis, which had existed for over 20 years. Ultrasound examination of the abdomen showed a strong adhesion of the bowel to the anterior abdominal wall. To prevent the risk of damage to the abdominal organs, it was decided to perform the nephrectomy retroperitoneoscopically and a simultaneous cholecystectomy from the same access. This procedure has three major advantages: no contact with the abdominal cavity when performing the access, the easiest access to the renal arteries, and the absence of a systematic increase in intraperitoneal pressure. Such access is of particular importance for the patients who have had previous interventions on the abdominal organs.

Aim.Clinical use of implants based on patient’s individual topographic anatomical features.Materials and methods.The paper describes two case reports involving the correction of nasal anatomical structure affected during the surgery for facial cancer. Using selective laser sintering technology we manufactured 2 intricate 3D-deformed individual implants from Ti70V30 alloy powders. Implant design was based on CAT/MRT data. Clinical use was conducted on the premises of the department of head and neck surgery in Chelyabinsk Regional Oncological Dispensary.Results.In the fi rst case we obtained an impressive functional result – huge and wide nasal cavity, nose skeleton, and easy nasal breathing. In 30 days we performed endoscopic video-analysis (via nasal passages) which showed that 65% of implant surface was covered with mucosa. In the second case, the designed implant allowed the combined surgery including excision of soft tissues, atypical resection of the upper jaw (left part) and the left cheek, left maxillary sinusotomy and reconstruction of the left part of the nose and the left cheek with implant and skin fl ap.Conclusion.Clinical use revealed pros and contras of the applied technology. Among contras there are relatively high cost of technology, high standards of competency of a surgeon, a programmer and engineers. Pros include free modeling and setting the implant parameters before operation, exact match between implant size/shape and topographic anatomical data of a certain patient.

Authors: Shevchenko O. P. , Kurabekova R. M. , Tsiroulnikova O. M.
Published: November 2016

This review of literature is dedicated to the analysis of the current studies of biomarkers, which could help predict immune tolerance development and identify the patients, who can safely minimize immunosuppression after liver transplantation. The review analyzed 46 sources of literature, more than half of those were published in the last fi ve years. Up to date advanced technologies are intensively developed, which help understand molecular mechanisms of normal, pathological and pharmacological processes involved in organ transplantations. However, there are no biomarkers yet validated for the identifi cation of immune tolerance development or individual prescription of immunosuppressants. Further data collection on patients along with the progress in bioinformatics could accelerate development of approaches for patient stratifi cation.

Aim.Analysis of relationship between transforming growth factor beta-1 (TGF-β1) level in blood and liver disease severity before and after liver transplantation in early age children with congenital liver diseases.Materials and methods.The study included 135 pediatric patients aged from 2 to 73 months with end-stage liver disease.Results.The level of TGF-β1 in the blood of children with liver failure on average was lower than in healthy children of the same age. The cytokine level depended on the liver disease etiology: in patients with biliary atresia, biliary hypoplasia, Alagille syndrome, Byler disease and other diseases it was lower than that at Caroli disease when it did not differ from the level in healthy children. The level of cytokine in the blood plasma of patients was associated with the severity of hepatic fi brosis: in fi brosis of grade 1 and 4 it was lower than in fi brosis of grade 2 and 3. The liver transplantation from related living donor resulted in increase of TGF-β1 level in the blood plasma of patients regardless of the initial etiology and severity of the liver disease.Conclusion.The blood level of TGF-β1 refl ects liver disease severity in children with congenital liver diseases and may be used as a marker of liver function state before and after liver transplantation.

Aim.To evaluate the associations of genotypes of clinically relevant nucleotides rs11536865, rs913930 and rs5030717 of the TLR-4 gene with the risk of development and severity of early allograft dysfunction after liver transplantation.Materials and methods.A case-control study enrolling 71 patients was organized. Inclusion criteria: DBD liver transplantation. Exclusion criteria: living related liver transplantation, reduced graft transplantation, recipient’s age fewer than 18.Results.Within rs5030717 there were identifi ed three genotypes: AA (81.6%) and two genotypes with the minor G-allele: AG (12.6%) and GG (5.6%). Within rs913930 there identi- fi ed three genotypes: TT (59.1%) and two genotypes with the minor C-allele: C/T (29.5%) and CC (11.2%). The rs11536865 studying revealed no polymorphism (GG genotype). The early allograft liver dysfunction (EAD) developed in 19.7% of patients, the severe EAD in 11.2% of patients, septic complications in 14%, acute cellular rejection in 23.9% of cases. The C/T genotype of the TLR-4 gene in the SNP rs913930 sequence was closely associated with the EAD development (OR 4.8 to 1; p = 0.047; 95% CI 1–23.4). Рatients with the donor’s liver C/T genotype had a reliably higher proportion (%) of the HMGB1 positive hepatocytes in the donor’s bioptate, 21 (17–29%) vs the СС+TT genotypes, 16 (10–19%) (Mann–Whitney test, p = 0.01). The CD68 expression in the liver bioptate at the donor’s stage was reliably higher in the carriers of heterozygotes in the SNP rs913930 (C/T genotype) and in the SNP rs5030717 (AG genotype), (Mann–Whitney test, p = 0.03). Signifi cant positive correlation between the CD68 expression in the donor’s liver bioptates and the IL-23 level in the hepatic vein has been determined in an hour after the portal reperfusion (ρ = 0.62; p = 0.04) as well as between the HMGB1 expression in the donor’s liver bioptates and the АSТ level in 24 hours after the reperfusion (r = 0.4; p = 0.02). The HMGB1 staining in the donor’s liver bioptates was higher in the EAD patients, 21 (20; 29) cells/mm2 in comparison with the patients without EAD, 16 (12; 18) (Mann–Whitney test, p = 0.0036).Conclusion.The early allograft liver dysfunction is associated with the genetic predisposition caused by the TLR-4 gene polymorphism and is implemented via the HMGB1, Kupffer cells and IL-23 activation.

The need of circulatory support systems in the treatment of chronic heart failure is increasing constantly, as 20% of the patients on the waiting list die every year. Despite the great need for mechanical heart support systems, the use of available systems is limited by its expensiveness. In addition, there is no one system that is 100% responsible to all medical and technical requirements and that would be completely safe for patient. Therefore, further research in the field of circulatory support systems considering health and technical requirements is relevant. One of the new directions in the study are disc pumps of viscous friction for liquid transporting, based on the Tesla pump principle. The operation principle of such pumps is based on the phenomenon of the boundary layer which is formed on the disk rotating in a fluid. There are experimental studies of models with different variants of the rotor suspension, various forms and numbers of the disks, forms of the pump housing. However, none of the above samples was brought to clinical trials. Furthermore, despite the potential of that model there have been no pumps of similar type used so far in circulatory support systems. Published data provide a basis for further development and testing of the pump model and allow hoping for leveling a number of significant shortcomings of modern left ventricular bypass systems.

Aim.Controlled treatment of the physico-chemical and mechanical properties of a three-dimensional crosslinked matrix based on reactive chitosan.Materials and methods.The three-dimensional matrices were obtained using photosensitive composition based on allyl chitosan (5 wt%), poly(ethylene glycol) diacrylate (8 wt%) and the photoinitiator Irgacure 2959 (1 wt%) by laser stereolithography setting. The kinetic swelling curves were constructed for structures in the base and salt forms of chitosan using gravimetric method and the contact angles were measured using droplet spreading. The supercritical fl uid setting (40 °C, 12 MPa) was used to process matrices during 1.5 hours. Using nanohardness Piuma Nanoindenter we calculated values of Young’s modulus. The study of cytotoxicity was performed by direct contact with the culture of the NIH 3T3 mouse fi broblast cell line.Results.Architectonics of matrices fully repeats the program model. Matrices are uniform throughout and retain their shape after being transferred to the base form. Matrices compressed by 5% after treatment in supercritical carbon dioxide (scCO2 ). The elastic modulus of matrices after scCO2 treatment is 4 times higher than the original matrix. The kinetic swelling curves have similar form. In this case the maximum degree of swelling for matrices in base form is 2–2.5 times greater than that of matrices in salt form. There was a surface hydrophobization after the material was transferred to the base form: the contact angle is 94°, and for the salt form it is 66°. The basic form absorbs liquid approximately 1.6 times faster. The fi lm thickness was increased in the area of contact with the liquid droplets after absorption by 133 and 87% for the base and the salt forms, respectively. Treatment of samples in scCO2 reduces their cytotoxicity from 2 degree of reaction (initial samples) down to 1 degree of reaction.Conclusion.The use of supercritical carbon dioxide for scaffolds allows improving biocompatibility of the applied material for 1 degree and increasing the elastic modulus of the material more than 3 times. Allyl chitosan forms stable three-dimensional networks during laser photopolymerization. This enables desorbing toxic low molecular weight component without destruction of the matrix structure.

ABSTRACT: Despite the increasing use of oregano ( Origanum vulgare L.) essential oil for therapeutic purposes, pre- and postnatal development of animals offspring exposed to this oil has not yet been evaluated. In line with previous concerns of genotoxicity, in this study adult rats were exposed to different doses of oregano essential oil (3, 9 and 27% vol/vol) during pre-mating, mating, gestation and lactation. Prenatal screening included fetal development and uterine inspection, where the reproductive rate of females such as breeding, pregnancy, delivery, viability and post-implantation loss rate were measured. Postnatal evaluation of rat offspring included motor development, neuroendocrine and behavioral assessment. Body weight of rat dams and signs of dystocia were evaluated daily. Development of physic characteristics and reflex tests of puppies were also assessed. Additionally, these rats, when adults, were submitted to sexual and open field behavioral tests. The main differences among the groups were observed in the indices of mating, pregnancy and post-implantation loss (P<0.01). Results demonstrated that the treatment of parental generation with oregano essential oil has the potential to affect the developing fetuses at the highest dose used, but without causing maternal toxicity and changes in general behavior and development of the progeny.

Published: November 2016

ABSTRACT: In this study, we aimed to investigate Cosmopolites sordidus (Coleoptera: Dryophthoridae ) infestation among different banana genotypes in a commercial banana orchard over the course of 30 months. Banana root borer infestation was compared in 20 banana genotypes, including five varieties and 15 hybrids. Overall, we observed that 94.17% of pest infestation cases occurred in the cortex region, and only 5.83% occurred in the central cylinder. Genotypes least sensitive to infestation were the Prata Anã (AAB) and Pacovan (AAB) varieties, where no damage was recorded. Among the hybrid genotypes, PV 9401 and BRS Fhia 18 showed intermediate levels of sensitivity, while BRS Tropical hybrids (AAAB), PA 9401 (AAAB), BRS Vitoria (AAAB), YB 4203 (AAAB), and Bucaneiro (AAAA) were the most sensitive to attack by banana root borer. This study demonstrated that the infestation of the banana root borer varies according banana plant genotype, and the utilization of less susceptible genotypes could reduce infestation rates of C. sordidus.

ABSTRACT: Campomanesia adamantium is a native fruit species of the Cerrado and is used in food and medicines and as bee pasture. The chemical composition of essential oils obtained from plants of the same species have varying constituent proportions due to the influence of extractive factors, environmental, genetic and ontogenetic. This study aimed to identify the influence of hydrodistillation time on the content and chemical composition of essential oil extracted from the leaves of C. adamantium . Treatments consisted of five extraction times (1, 2, 3, 4, and 5h) using Clevenger with five replications in a completely randomized design. It was observed that after two hours of hydrodistillation, the essential oil content remains constant. Regarding the chemical constituents of essential oil, variation of the proportions of the compounds tested occurred at all hydrodistillation times. The compounds spathulenol oxygenated sesquiterpenes and caryophyllene oxide were the majority in the five hydrodistillation times.

ABSTRACT: This study aimed to compare the temperatures in the mass of bulk soybeans ( Glycine max ) in warehouses with isolated vents and vent-combined exhaustion. A completely randomized design was used, with two treatments and ten repetitions. Treatments consisted of warehouse with curved vents and warehouse with curved + static exhaust vents. Each repetition contained the average of all readings in three days in all cables of the warehouse part under study, totaling 10 repetitions per month. The variable analyzed was the temperature in the grain mass in the lower, middle and upper parts of the warehouse from January to May 2012. The environment temperature and humidity were also registered. Static hoods, along with curved vents on the roof of the warehouse showed a tendency to reduce the temperature of the soybean mass with decrease in environmental temperature and increase in relative environmental humidity.

ABSTRACT: Defoliation caused by Black Sigatoka in yield and quality of banana 'Nanica' was stimulated in this study. A completely randomized 2x8 factorial design with six repetitions was used, in which period of bunch formation and number of leaves at flowering were established as factors. Plants for defoliation were selected on 04/05/2013 (Period 1), and on 07/01/2014 (Period 2). Six to to 13 leaves remained per plant by removing those with more than 50% of blade with injury or senescence. More appropriate climatic conditions before and after flowering, promoted greater mass accumulation in the bunch in Period 2. The increased number of leaves at flowering increased the length of the fruit and the mass of 4th hand, as well as the bunch mass and postharvest period. Defoliation is suggested only for non-functional leaves as well as the maintenance of at least 10 leaves per plant, independent of the period of bunch formation.

ABSTRACT: The intensive use of plant protection products in rice paddy fields ( Oryza sativa L.) has caused concern about the environmental impact on communities of non-target organisms that are natural inhabitants in these agroecosystems. The purpose of this review is to analyze the data currently available in the literature about some important fungicides and insecticides (such as trifloxystrobin, tebuconazole, tricyclazole, lambda-cyhalothrin, and thiamethoxam), which are currently used to control pests and diseases in rice paddy fields, as well as their effects on the community of non-target aquatic organisms.

Published: November 2016

ABSTRACT: This study aimed to determine the most appropriate method to assess the sunn hemp ( Crotalaria juncea L.) seed vigor in the accelerated aging test. Five seed lots from harvest 2007/2008 were evaluated for germination, vigor and seedling emergence in the field. Accelerated aging test was performed at 41°C during 48, 72 and 96 hours, with and without sodium chloride saturated solution. Then, the promising procedure was also performed for 2008/2009 and 2009/2010 harvests. In the traditional accelerated aging test, the no-uniform water acquisition by the seeds adversely affected results. Accelerated aging test with sodium chloride saturated solution is the most appropriate method to evaluate the physiological potential of sunn hemp seeds, and the combination of 41°C and 96 hours is efficient for separating of seed lots in different vigor levels.

ABSTRACT: The present study evaluated the minimum alveolar concentration of isoflurane (ISOMAC) in twenty three dogs premedicated with acepromazine (0.02mgkg-1) and morphine (0.5mgkg-1) and administered racemic (RK) or S(+)-ketamine (SK). Dogs randomly received a single dose (3mgkg-1, IM) of either RK or SK 15minutes after anesthetic induction with propofol. The ISOMAC was determined by the up-and-down method. Approximately 20 minutes after administration of RK or SK, a surgical noxious stimulus was applied and the response evaluated. The ISOMAC was 0.50±0.01% in the RK group (n=10) and 0.31±0.04% in the SK group (n=13). The ISOMAC was 38% lower in the SK group compared to the RK group. Results of the present study revealed that in dogs premedicated with acepromazine and morphine, IM administration of 3mgkg-1 ketamine approximately 20 minutes before the noxious stimulus produced clinically important reduction in the ISOMAC and the MAC-sparing effect was significantly greater with SK compared to RK.

ABSTRACT: Renal cell carcinoma, especially with extensive involvement of peritoneal cavity, is rarely described in horses. This study described a case of renal cell carcinoma in an 8-year-old mare, which presented with an enlargement in the left flank, decreased appetite and straining to defecate. Clinically, a tumor in the left retroperitoneal space was detected by rectal examination and ultrasonography. The animal died after one month of clinical evolution. At necropsy, the left kidney was completely effaced by a 50cm in diameter, irregular, round, lobulated cystic mass with necro-hemorrhagic areas. Within the peritoneal cavity, there was severe hemoperitoneum and numerous sessile and pedunculated masses ranging from 2.0 to 15.0cm diameter that were attached to the visceral and parietal peritoneum. Histologically, the primary neoplasia and its metastasis were composed by a proliferation of epithelial cells, which were arranged in a tubulopapillary pattern. Diagnosis of renal cell carcinoma with peritoneal carcinomatosis and hemoperitoneum was based on macroscopic aspects, and mainly on the histological features.

ABSTRACT: Visceral leishmaniasis (VL) is caused by the protozoon Leishmania infantum . Transmission of this parasite to hosts occurs mainly through the bite of infected sand flies. However, alternative infection routes have been hypothesized, especially in areas where the biological vector is absent. The exact time of infection and whether in utero transmission occurs have still not been fully elucidated. This report demonstrates molecular evidence of vertical transmission of L. infantum from a pregnant dog to the embryo. Samples (e.g. vulva, vagina, cervix, uterine body, uterine horn and ovaries) from a female naturally infected by L. infantum and from her embryo were molecularly analyzed by means of qPCR and cPCR followed by DNA sequencing. The gestational age was estimated to be 23±1 day. Through qPCR, the presence of L. infantum DNA was detected in all the samples analyzed (n=7), including the embryo, conversely through cPCR, only four samples (vagina, cervix, uterine body and embryo) were positive. This study demonstrated that transmission of L. infantum from a pregnant dog to the embryo might occur in the early days of pregnancy. In conclusion, this is the first report showing L. infantum infecting a canine embryo.

ABSTRACT Objective: to investigate potential drug-drug interactions (PDDI) in patients with HIV infection on antiretroviral therapy. Methods: a cross-sectional study was conducted on 161 adults with HIV infection. Clinical, socio demographic, and antiretroviral treatment data were collected. To analyze the potential drug interactions, we used the software Micromedex(r). Statistical analysis was performed by binary logistic regression, with a p-value of ≤0.05 considered statistically significant. Results: of the participants, 52.2% were exposed to potential drug-drug interactions. In total, there were 218 potential drug-drug interactions, of which 79.8% occurred between drugs used for antiretroviral therapy. There was an association between the use of five or more medications and potential drug-drug interactions (p = 0.000) and between the time period of antiretroviral therapy being over six years and potential drug-drug interactions (p < 0.00). The clinical impact was prevalent sedation and cardiotoxicity. Conclusions: the PDDI identified in this study of moderate and higher severity are events that not only affect the therapeutic response leading to toxicity in the central nervous and cardiovascular systems, but also can interfere in tests used for detection of HIV resistance to antiretroviral drugs.
