Authors: Ramírez-Martínez Agustín , De los Santos-Posadas Héctor M. , Ángeles-Pérez Gregorio , González-Guillén Manuel J. , Santiago-García Wenceslao
Published: December 2020

En México los bosques de clima templado manejados presen­tan en su mayoría una repoblación de origen natural y niveles de densidad diferentes entre rodales. Los modelos de mortali­dad asumen tasa de disminución constante para todas las eda­des, índices de sitio y densidades. El objetivo de este estudio fue determinar las tasas de mortalidad en tres densidades iniciales y construir un sistema de crecimiento y rendimiento (SCR) de Pinus patula en presencia de latifoliadas, en la región de Zacualti­pán, Hidalgo, México. Los datos provinieron de tres inventarios realizados en 2013, 2014 y 2016 de 160 sitios de 400 m2. La productividad se describió por medio del patrón de crecimiento en altura dominante de tipo anamórfico con el modelo Hossfeld IV. El ajuste de los modelos de mortalidad generó tasas de decre­cimiento anuales de 2.47, 1.17 y 0.81% con densidades mayor que 2000, entre 1000 y 2000 y menor que 1000 árboles ha–1, respectivamente. El SCR mostró que los rendimientos mayores correspondieron a la densidad inicial de 2000 árboles ha–1 y los turnos técnicos estimados en volumen entre los 24 y 27 años. Con presencia del 5% de latifoliadas, a partir de los 5 años los turnos se encontraron entre los 20 y 23 años. En un índice de si­tio (IS) 36 el volumen de pino fue mayor que el volumen total (la suma de pinos y latifoliadas), mientras que en los IS 18, 24 y 30 las diferencias no fueron tan significativas. La biomasa fue mayor en todos los sitios con pinos más latifoliadas, dado que estas espe­cies concentran una mayor cantidad de biomasa en su estructura. En los sitios más productivos (IS 30 y 36) las latifoliadas tienden a afectar los rendimientos finales en volumen del pino. Por lo tanto, la aplicación de tratamientos silvícolas es necesaria para disminuir la proporción de estas especies.
RENDIMIENTO Y CALIDAD DE ÁCIDO CARMÍNICO DE Dactylopius coccus Costa EN DIFERENTES ALTURAS DE LA NOPALOTECA
Authors: Zacarías Alvarado José Rodolfo , Tovar Robles Clara Lourdes , Méndez Gallegos Santiago de Jesús , Magallanes Quintanar Rafael , Aquino Pérez Gildardo
Published: December 2020

Dactylopius coccus es un insecto de importancia comercial como fuente de un colorante natural denominado ácido carmínico. Para su producción comercial en cautiverio, se ha promovido la cría en cladodios suspendidos a diferentes alturas, en un sistema denominado “nopaloteca”. Sin embargo, se desconoce si su calidad y rendimiento es uniforme en los diferentes niveles. El objetivo de este estudio fue determinar la influencia de la altura del nivel en una “nopaloteca” y el índice de cosecha en la concentración de ácido carmínico (CAC, %) y peso fresco (PF, g) de D. coccus. La crianza del insecto se realizó en una “nopaloteca” de madera (3x3 m), con cuatro niveles de altura (0.5, 1.0, 1.50 y 2 m).  Durante el ciclo de cultivo se registró cada día la temperatura, la humedad relativa y la intensidad luminosa. Las hembras adultas se recolectaron en dos etapas del desarrollo: pre y postoviposición. La CAC más alta (19.2%) se obtuvo en 1.0 m de altura, aunque este nivel registró el PF más bajo con 3.5 g por cladodio, que expresa una correlación negativa entre la CAC y el PF. La recolecta en postoviposición generó una CAC superior (18.8%), aunque el PF se redujo. Tanto la humedad relativa (HR) como la iluminación total, pero principalmente la temperatura que incidió en cada nivel, influyeron en la calidad y el rendimiento de D. coccus, aunque de manera diferencial sobre ambos factores, lo cual indica la presencia de límites óptimos de desarrollo. Bajo las condiciones del estudio, el sistema de cría en “nopaloteca” produjo en promedio 4.5 g de cochinilla por cladodio y una CAC de 17.5%. Los niveles evaluados causaron diferencias en rendimiento y calidad, pero sus valores más altos se registraron en los niveles intermedios (1.0 y 1.5 m). El índice de cosecha recomendado para obtener mayor CAC fue la etapa de postoviposición.

Authors: Vázquez Aguirre Martha , Valencia Méndez Javier de Jesús , Barrientos Morales Manuel , Juárez López Noé Orlando , Córdova Izquierdo Alejandro , Pinos Rodríguez Juan Manuel , Juárez Mosqueda María de Lourdes
Published: December 2020

Los espermatozoides de toro exhiben estructuras específicas que protegen su ADN y, por lo tanto, las técnicas estándar utilizadas para el aislamiento del ADN somático no son eficientes. Así pues, nuestro objetivo fue diseñar un aislamiento del ADN de espermatozoides de toro que fuera económico, rápido y eficiente, con la hipótesis de que la combinación adecuada de agentes químicos y un conjunto de alternativas nos permitirían diseñar un método mejorado para extraer el ADN de los espermatozoides de toro para su utilización en los ensayos de PCR. Una serie de réplicas obtenidas de cinco eyaculados se utilizó para evaluar seis métodos de extracción de ADN de espermatozoides de toro: 1) el método convencional que utiliza la proteinasa K y el fenol-cloroformo; 2) el método de papaína, DTT, DMSO, CTAB y SDS (para solubilizar la teca perinuclear y reemplazar el fenol-cloroformo); 3) el método del detergente no iónico Brij 36-T para eliminar la membrana plasmática; 4) el método del DTT y la heparina para la descondensación de la cromatina nuclear; 5) el método SDS y; 6) el método CTAB para eliminar la membrana plasmática. Las muestras de ADN se analizaron espectrofotométricamente para determinar la concentración y la pureza del ADN, y luego se utilizaron en cinco cantidades (200, 100, 50, 25 y 12.5 ng) para los análisis de PCR. Para evaluar la repetibilidad del método, se realizaron réplicas del procedimiento más eficiente. Los resultados mostraron que el mejor método para la extracción de ADN de espermatozoides de toro fue el sexto, basado en el uso del CTAB como agente de remoción de membranas; papaína, DTT y DMSO como tampón de lisis y DTT, heparina y SDS como solución de descondensación, y se logró una concentración que oscilaba entre 63 y 154 ng µL-1 y una calidad óptima (A260/A280= 1.75 y 1.73) en la extracción de semen fresco y congelado, respectivamente. En conclusión, considerando las características estructurales del espermatozoide, diseñamos un método simple y eficiente para extraer el ADN de los espermatozoides de toro sin limitaciones en la PCR. Además, todo el procedimiento puede realizarse en un período corto de tiempo, sin necesidad de emplear el tratamiento con fenol-cloroformo y proteinasa K.

Single Stage Transanal Pull-Through for Hirschsprung’s Disease in Neonates: Our Early Experience
Authors: Bhatia Pradeep , Joshi Rakesh S , Ramji Jaishri , Bachani Mitesh , Uttarwar Amit
Published: December 2020

Objective: Hirschsprung’s disease is one of the common causes of intestinal obstruction in neonates. Transanal endorectal pull-through represents the latest development in the concept of the minimally invasive surgery for Hirschsprung’s disease. In this study, we present our early experience with single stage transanal pull through in neonates. Design: Retrospective study of neonates with single stage transanal pull-through done for Hirschsprung’s disease in our institute from January 2011 to January 2013. Material and Method: Five newborn boys who presented with Hirschsprung’s disease were studied. The selection criteria included radiological transition zone at rectosigmoid or mid-sigmoid region, weight more than 2 kg, no evidence of enterocolitis or sepsis and no associated major anomaly. Single stage transanal endorectal pull-through was done in these patients. The follow-up period ranged from 6 months to 2 years. Results: Five patients with a mean age of 26.4 days (range 15-45 days) and a mean weight of 2.6 Kg (range 2.2 to 3.7 Kg) underwent transanal endorectal pull through. The mean operating time was 68 min (range 60 to 120 min). The average intra-operative blood loss was 20 ml (range – 10 to 30 ml) and the average length of bowel resected was 12.8 cm (range – 10 to 18 cm). Post-operatively patients passed first stool between 2nd and 3rd day. Oral feeding was resumed on 5th to 6th post-operative day. The average post-operative duration of stay in hospital was 10 days. None of the patients had post-operative bleeding, urethral injury, anastomotic leak or retraction of anastomotic site. Three patients developed perianal excoriation and one patient had post-operative enterocolitis. No mortality occurred in the series. Conclusion: Advancement in pediatric anaesthesia, availability of pediatric surgical expertise, improvement in pre-operative and post-operative management and nursing care has made single stage transanal pull-through in neonates a feasible option. The early results are comparable to single stage or multistage surgery in older children.

Authors: Saeed Adel A. M. , Ali Aisha Mohammed , Fdhel Taha Abubaker
Published: December 2020

Plants have abundant bioactive components and play an important role in folk medicine, owing to their health beneﬁts in the treatment of many diseases, partially due to the secondary metabolite compositions. Nonetheless, detailed information on these substances is still limited. The recent work was aimed at investigating the bioactive substances of two Yemeni medicinal plants (i.e. Plectranthus asirensis and Plectranthus amboinicus) using reversed-phase high-performance liquid chromatography-electrospray ionization-mass spectrometry in a positive ionization mode. The proposed method provided a tentative identiﬁcation of several constituents such as alkaloids, fatty acids, steroids, and terpenoids. The obtained results highlight the importance of studied plants as a promising natural source of bioactive compounds.

Authors: Chougala Manjula R. , Ramachandra A. C.
Published: December 2020

Digital Image Processing (DIP) applications in agriculture sector is becoming popular because of its fast, cost-effective and accurate solutions related to diseases and marketing. The hands-on solutions are being provided through various applications. Leaf Sopot disease has become the major constraint in the turmeric cultivation in India. Colletotrichum capsici is a fungal disease commonly known as leaf Spot. The brown spots of 4-5 cm length and 2-3 cm width with a grey centre are found on either surface of the leaves. If not treated timely, it causes the heavy loss in terms of quality and quantity. This paper proposes the methodology using Image Processing for measuring the severity of this disease in plant pathology. The image acquisition of infected leaves is done in the first stage then the images are pre-processed. Histogram is used for colour feature extraction The Edge detection methodology is used for infected area measurement and the results are fed to disease classifier to identify the stage of disease. This helps the plant pathologist in preparing consultative module to eradicate the disease completely.

Frequent Itemsets Used in Mining of Train Delays
Authors: Babu D. Kishore , Satish Y Naga , Kumar G. L. N. V. S.
Published: December 2020

The Indian railway network has a high traffic density with Vijayawada as its gravity center. The star-shape of the network implies heavily loaded bifurcations in which knock-on delays are likely to occur. Knock-on delays should be minimized to improve the total punctuality in the network. Based on experience, the most critical junctions in the traffic flow are known, but others might be hidden. To reveal the hidden patterns of trains passing delays to each other, we study, adapt and apply the state-of-the-art techniques for mining frequent episodes to this specific problem.

YUNINI COPY OF SAHIH AL-BUKHARI
Authors: KHOLMUMINOV FERUZ , SOTVOLDIYEV OYBEK
Published: December 2020

Among the collections of hadiths, the work of Imam al-Bukhari “Sahih al-Bukhari” is recognized as the most reliable book of hadiths. From the history of the creation of the work, it is known that Imam al-Bukhari created this work with great patience and perseverance for 16 years. It should be noted that the ideal and perfect state in which it has come down to our days is the result of the enormous work put into it. This process consisted of several stages. At the frst stage, several storytellers listened to “Sahih” from Imam Bukhari himself and wrote the book directly in the presence of the Imam. The storytellers, in turn, were copied by their students. Gradually, various manuscripts of the work became widespread in Muslim countries. With the further distribution of copies, diﬀerences began to appear between them. In this regard, an important task was to generalize all copies of the manuscript, identify the diﬀerences between them, and compile the most reliable text of the work. Among those who tried to carry out this noble work was Sharafddin al-Yunini (d. 701/1302). By comparing his various narratives, he created the most authentic text, Sahih al-Bukhari, known to date. As a result of his diligence and great eﬀorts in the feld of science, the alYunini’s version became the main text of Sahih al-Bukhari.

TERMINOLOGY AS A SPECIAL LINGUISTIC LAYER IN THE MODERN ARABIC LANGUAGE
Authors: MAMADJANOVA VIKTORIA
Published: December 2020

This article deals with the problems of the formation and functioning of modern terminology in the countries of the Arab East. It is important to trace the factors that inﬂuenced the process of forming its lexical composition. Following the national liberation movement of the Arab countries, starting from the second half of the 20th century has repeatedly raised the issue of the ofcial status of the Arabic language at the regional and global levels. The nationalization of education was a fundamental principle of the language of the Arab countries’ policies. It was about switching the entire national education system to Arabic, and the introduction of classical language as everyday communication.The transformation of the political situation in the Arab region was accompanied by the systematic repression of the colonial language, lexical enrichment of the composition of the modern literary language, the development of a national terminology. The rapid growth of science and technology has led to the emergence in the Arabic of many new concepts and intensive borrowing of foreign language terms. The task was to provide the new content in education that meets the needs of the world’s scientifc and technological progress. In the process of adaptation, foreign-language terms are adapted to the conditions of functioning of the Arabic language. The sociolinguistics approach to the study of Arabic terminology has allowed us to identify the main trends of its development.

This study was conducted to immunohistochemically investigate Trk-A receptor levels in pancreas tissue of mice treated by cumin (Cuminum cyminum) plant essential oil. Mice were grouped into control group (n = 10) and trial group (n = 10). No application was performed to the mice in the control group. The mice in trial group were treated by 500 mg/kg of oral cumin essential oil every 24 hours for two days. At the end of study, the pancreatic tissues obtained were blocked in paraffin following routine histological processes. Triple staining was performed to the sections taken from these blocks to examine general histological structure of pancreas. Acinus, islets of Langerhans, pars initialis, pars excretory and ductus excretorius were determined in mice pancreas. Immunohistochemical studies showed that all mice had Trk-A immunoreactivity in pancreatic tissue. Moderate immunoreactivity in acini and weak immunoreactivity in islets of Langerhans and excretory ducts were detected in pancreas tissue of mice in control and trial groups. It was determined that there was no difference between the groups in terms of Trk-A immunoreactivity in acini and islets of Langerhans. Based on the immunohistochemical results, cumin was used in field of diuretic, degassing, digestion facilitator, antimicrobial and antidiabetic effects in field of traditional medicine; It was concluded that Trk-A receptor synthesized from pancreatic tissue does not change its levels.

The aim of this study was to investigate the effects of acrylamide on Capoeta capoeta (Guldensttead 1773) by histopathological, electrophoretic and biochemical methods. Capoeta capoeta caught from Kars stream were used in the study. The fish were divided into 5 groups, each containing 10 pieces, and placed in 300 liter tanks with tap water. Group 1 was kept as a negative control. 20 mg / kg cyclophosphamide given to group 2 (i.p. positive control group), 10 mg / L acrylamide given to group 3, 20 mg / L acrylamide given to group 4 and 30 mg / L acrylamide given to group 5. After all groups were kept in tanks for 4 days, blood and tissue samples taken from fish were investigated by histopathological, electrophoretic and biochemical methods.
As a result of the analyzes serum AST and ALT levels were decreased in the other groups compared to the negative control group and serum TAS levels were significantly increased in the 30 mg / L acrylamide group compared to the negative control group (P < 0.01). Compared with the negative control group, TOS levels were increased in all groups. When the electropherogram obtained from SDS-PAGE was examined, it was determined increases and decreases at 21 kD, 27 kD, 36 kD, 42 kD, 48 kD, 54 kD protein expressions in groups with different concentrations compared to the negative control group. It was observed that protein expressions were inhibited especially in the group treated with 20 mg / L acrylamide. As a result of histopathological examinations; increased degenerations were detected in the gill and liver tissues of fish due to the concentration of acrylamide. As a result; acrylamide treatment caused toxic effects on C. capoeta after this varying time intervals and concentrations.

The Fair Calculations Act seeks to prohibit courts from using race, ethnicity, gender, religion, or actual or perceived sexual orientation in awarding damages to plaintiffs in civil actions. The legislation died in the 114th Congress but a similar bill was introduced in the House of Representatives and the Senate on September 19, 2019 and is in the early stage of the legislative process. California's Senate Bill No. 41 (2019) which is similar to the Fair Calculations Act became law on January 1, 2020. This case study examines economic damages of a male and female child suffering the same traumatic injury from an automobile collision shortly after birth assuming that some future version of the Fair Calculation Act becomes law.
Imported Food Price Shocks and Socio-Political Instability
Authors: Meyimdjui Carine
Published: December 2020

Using a panel of 101 low- and middle-income countries with data covering the period 1980-2012, this paper applies various econometric approaches that deal with endogeneity issues to assess the impact of food price shocks on socio-political instability once fiscal policy and remittances have been accounted for. It focuses on import prices to reflect the vulnerability of importer countries / net-buyer households to food price shocks. The paper finds that import food price shocks strongly increase the likelihood of socio-political instability. This effect is greater in countries with lower levels of private credit and income per capita. On the other hand, while remittances seem to dampen the adverse effect of import food price shocks on socio-political instability in almost all countries, the mitigating role of fiscal policy is significant only in countries with low-levels of private credit.
The Behavior of Fixed-income Funds during COVID-19 Market Turmoil
Authors: Hespeler Frank , Suntheim Felix
Published: December 2020

This note analyzes the stress experienced (and caused) by open-end mutual funds during the March COVID-19 stress episode, with a focus on global fixed-income funds. In light of increased valuation uncertainty, funds experienced a short period of intense withdrawals while the market liquidity of their holdings deteriorated substantially. To cover redemptions, afflicted funds predominantly shed liquid assets first—for example, cash, cash equivalents, and US Treasury securities. But forced asset sales amplified price pressures in markets and contributed to liquidity falling across fixed-income markets. This drop in market liquidity, as well as the general stress in financial markets, may have led to fund investors becoming even more sensitive to challenging portfolio performance and encouraged further withdrawals. Only after central banks intervened, directly and indirectly supporting asset managers, did liquidity and redemption stress subside. Overall, the March episode validated the financial-stability concerns about liquidity vulnerabilities in the fund industry and calls for further action to address them.
