Optimization of Protease Production by Streptomyces SP. LCJ1A Using Response Surface Methodology
Authors: Dhavala Swarna  , J. Joel Gnanadoss  
Published: January 2021

Protease is an industrially important enzyme obtained from plants and animals. Production of high amounts of protease at low cost is necessary for its use in different commercial applications. The main objective of this work was to formulate a suitable medium and to optimize various parameters for protease production by Streptomyces sp. LCJ1A which was isolated from Pichavaram mangroves, Tamil Nadu, India. The organism was quantitatively and qualitatively screened for protease production. Sequencing of 16S rRNA was done and the sequence was deposited in NCBI and Accession no. KU 870428 was obtained. For optimization, the conventional one-time factor method followed by the Plackett-Burman design was used to optimize various media components. Variables with a significant influence on the production of protease have been identified. Variables such as maltose, peptone, pH and temperature have shown its strong impact on protease production and the ideal concentration of these factors was further investigated by Response Surface Methodology. The Optimum values of tested variables for favourable protease production were: Maltose, peptone, pH and temperature. Further, the interaction effects of maltose and peptone were found to be extremely important suggesting that both components were extremely crucial for protease production. 186.92 U/mL of protease enzyme was obtained in the experimental study which was close to the predicted value of 190.67 U/mL, which could validate the model. Using such optimized variables, the protease production was increased by 10 times when compared with the unoptimized medium. This is the first report on the conventional and statistical optimization of protease production from Streptomyces sp. LCJ1A. This study also showed that statistical methods are indeed a better approach for optimization of media, when compared with conventional one- factor-at-a-time method in terms of an enhanced protease yield in a short time

Mechanical low back pain is the main common reason for referral to physiotherapy clinic, and a chief reason for people complains, and both men and women are equally reported to be affected by this condition. It is found that core stabilization exercises have got significant improvement when compared to conventional back care exercises in improving the function and in relieving pain. To see the effectiveness of core muscles activation over conventional exercises along with Interferential Therapy (IFT) in each group for the reduction of pain and to increase the range of motion and improve the disability in subjects with mechanical low back pain. This is an experimental study where pre and post design were used with 40 subjects with mechanical low back pain were taken considering the selection criteria and divided into two groups. 20 subjects in Group-A received Core muscles activation exercises and IFT with pre and post test analysis and 20 subjects in Group-B received Conventional exercises and IFT with pre and post test analysis. Visual Analogue Scale (VAS) for pain intensity, Revised Oswestry Disability Index (R-ODI) for the disability improvement and Goniometry for range of motion. Statistical analysis was done by using paired ‘t’ tests which showed significant improvement in reducing pain, improving the quality of life and increasing the ROM in Group-A as compared to Group-B but as p > 0.05 so it was non significant. It is concluded that subjects in Group-A who received Core muscles activation exercises are more effective as compared to Group-B who received Conventional exercises and it is found that IFT with core activation exercises is very effective in reducing pain, increasing the ROM and improving the disability.

Authors: Satyabrata Sahoo  , Ria Rakshit  
Published: January 2021

The emergence of the 2019 novel coronavirus SARS-CoV-2, causing a highly contagious disease COVID-19 poses a tremendous global public health concern. As the disease is quickly developing into a worldwide pandemic, a careful analysis of its origin, evolution, transmission, and cellular mechanism is urgently needed to combat the deadly virus. Successful isolation of the 2019-nCoV has promoted some bioinformatic studies to understand the viral origin and the feature of its infectivity. However, at this stage, much remains unclear about the origin of the novel virus and to be investigated to develop ways to control its spread. The mechanisms associated with the infectiousness of SARS-CoV-2 are not entirely understood. The current knowledge in 2019-nCoV pathogenicity and transmissibility along with several commonly known emerging viruses and information is very much important for better control of the disease. So far, the treatment is only supportive. Any antiviral agent is yet to emerge. The scientific community raced to understand the pathogenesis of the disease for developing treatment options. Extensive research is going on to understand the host response to the pandemic virus to develop the disease therapeutic. To fill the knowledge gap about the human immune response to SARS-CoV- 2 infections that may help in designing the appropriate immune intervention for treatment, diagnosis, and prophylactic/therapeutic vaccines against COVID-19, we present hereby a brief review on the genomic organization, origin, and evolution, transmission and pathogenesis of the novel virus, and clinical spectrum and possible preventive measures against COVID-19 which may be used for future references.
El problema general del desarrollo del Marxismo en el siglo XXI.
Authors: Güendell Hermann 
Published: January 2021

Con la consolidación del neoliberalismo como modelo de desarrollo por seguir en las sociedades occidentales, ha reaparecido un capitalismo sin tema social que profundiza las inmensas diferencias sociales existentes. Ello ha producido, como efecto inverso, la necesidad política de conceptualizar una alternativa de organización social que dé respuesta a nuestra situación humana. Esta alternativa es el socialismo. Con ello se abre una rica posibilidad para que el marxismo recupere el protagonismo político que tuvo en el siglo XX. Esto exige un replanteamiento conceptual y organizativo que le dé efectividad política en el contexto del capitalismo del siglo XXI. Tal reto del presente será superado solo si el marxismo, como discurso de la revolución, acepta desarrollos innovadores tanto en el plano teórico como en el organizativo. En este ensayo demuestro que esto es posible, elucidando el mecanismo epistemológico por el cual se da, y ejemplifico, a su vez, con algunos desarrollos innovadores que se han presentado a en la historia del marxismo.
El cultivo de la palma aceitera en Costa Rica en el contexto del TLC con los Estados unidos de Norteamérica
Authors: Clare Patricia 
Published: January 2021

El mercado mundial de aceites y grasas es complejo, ya que son productos sustituibles entre sí. Costa Rica participa de este mercado por medio del aceite de palma, el cual ocupa un lugar importante en las exportaciones nacionales. Su cultivo se concentra en el Pacífico Central y en el Pacífico Sur, que son regiones económicamente deprimidas, por lo que la palma adquiere relevancia como una de las pocas actividades rentables en la zona. La producción palmera se encuentra concentrada en un porcentaje importante en manos de una transnacional, en menor medida en un sector cooperativo y en algunos pocos productores independientes. El sector cooperativo cuenta con su propia procesadora y está adquiriendo otra planta más. En el contexto del TLC la producción aceitera se ve amenazada, pues si el tratado se aprueba en su versión actual, se verá obligado a competir con el aceite de soya norteamericano. A diferencia de otros cultivos cuya producción se encuentra atomizada a lo largo del territorio, diluyendo así los efectos en sectores más amplios, la palma se concentra en una región. Se desarticularía también un sector cooperativo en despegue, que hasta el momento ha sido exitoso.
Ricoeur's theory of narrative time and one hundred years of solitude
Authors: Álvarez Martínez Luis Gustavo 
Published: January 2021

Paul Ricoeur´s narrative theory of time proposes that we, during our reading, move backwards and forward in narrative time and that “temporality springs forth in the plural unity of future, past and present” (167) . In utilizing his theory of time and the idea of cyclical time as a prominent characteristic in twentieth century literature, I attempt to apply his intriguing theory to an exemplary novel, One Hundred Years of Solitude (1967) by the Colombian Gabriel García Márquez. The essay demonstrates how the circularity of the imaginary travel and the linearity of the quest as such are thus put together. Indeed, time is circular and recurrent rather than rectilinear and progressive in this novel wherein readers are moved between present, past and future time.

Published: January 2021

To configure the control systems of the ship movement along the trajectory, it is necessary to be concerned with the parameters of its controllability. There has been proposed building
a matrix model based on measurements of the state vector of a controlled object. The construction of the model is considered on the example of the problem of ship course control. An algorithm for determining the matrix coefficients of the selected model is proposed. The operation of the considered algorithm has been checked for square matrices by finding their inverse matrices, as well as for rectangular matrices for which the pseudo inverse matrix was found. The illustration of the proposed approach is carried out using the example of a simple 1-order linear Nomoto model. The considered approach is quite universal and can be applied to higher order models, including nonlinear ones.

El objetivo fue realizar una revisión sistemática de los hábitos nutricionales en practicantes de deportes gimnásticos. Se revisaron las bases de datos WOS, Scopus, Pubdmed, Sport Discuss y Google Scholar, entre los años 2000-2020, siguiendo los principios de la declaración PRISMA. La selección fue realizada por dos investigadores en dos etapas (cribado y aplicación de criterios de elegibilidad). Se registraron edad, sexo, tamaño muestral, calidad metodológica, país, variables, instrumento y resultados en 15 artículos que cumplieron los criterios de inclusión. La mayoría de los estudios resaltan que los hábitos nutricionales entre gimnastas son peores en el género femenino que masculino, sin cumplir en general con las recomendaciones para esta población. Los instrumentos más utilizados fueron el recordatorio dietético de 7 días 33,33% y el cuestionario de calidad de vida mediterránea y registro de 3 días, ambos 20%. Se concluye que los gimnastas en general, no tienen buenos hábitos alimentarios, consumiendo dietas desequilibradas. Es necesario desarrollar programas para promover hábitos nutricionales saludables en esta población.

Authors: Hamidah Hamidah 
Published: January 2021

ABSTRACT
Organic farming continues to grow in line with the rapid market demand for organic fruit and vegetables. In our country, organic agriculture is experiencing rapid development due to the fact that agricultural products, especially fresh vegetables and fruit, are grown using organic farming systems. Organic agricultural products are starting to attract consumers, especially the upper middle class, who are willing to pay more for food products that are healthy, safe, and environmentally friendly. The purpose of this study was to determine the use of organic fertilizers for washing rice water and pruning water shoots on the growth and yield of tomato plants. The research was conducted in Gunung Kelua village, Samarinda, East Kalimantan for approximately 4 (four) months, from March to July 2020. This study used a randomized block design arranged 3x2 factorial with 3 replications. The first factor is liquid organic fertilizer which consists of 3 (three) levels, including: P0 Without Treatment, P1 (Liquid Organic Fertilizer 250 ml / l water), P2 (Liquid Organic Fertilizer 500 ml / l water). The second factor is pruning water shoots consisting of 2 (two), namely T0 without pruning water shoots on tomato plants, T1 by pruning water shoots on tomato plants. The results showed that the application of liquid organic fertilizer had no significant effect on plant height, but had a significant effect on the number of fruits and production.

Published: January 2021

The World Health Organization (WHO) describes infertility as a disability for couples in childbirth to attain pregnancy within 12 months of daily sexual intercourse. The reproductive years of women starts when she starts her menstrual cycle during puberty and capacity to have a child typically ends about age (45) years. However, it may be possible for a woman to become pregnant before her cycles end with menopause. Infertility affects 13–20 per cent of couples worldwide, regardless of race or ethnicity. The present study aim was To study the levels of prolactin and beta hCG in female infertility. And To correlate the levels of prolactin and beta hCG in infertile womens and healthy controls. The present study was conducted in the departments of biochemistry and dept. of obstetrics and gynaecology. The study was conducted on two groups of 40 infertile Females and 40 healthy controls. Serum sample used for estimation of prolactin and hCG, assessed by dry chemistry analyzer. Serum prolactin levels in infertile females is 33.96±11.46 and hCG levels was 86.38±12.45, which was higher in infertile female as compared to healthy control with a p-value of<0.05. The present study concludes that Hyperprolactinemia is a major contributing hormonal factor in infertility among infertile women and, as such, prolactin and hCG should be measured in infertile women.
