Root induction of Phalaenopsis amabilis with various types and concentration of banana extract by in vitro

Root induction is an important step in plant propagation by in vitro. Root stimulation can occur in the presence of the hormones auxin and gibberellins which can be obtained from other plants, one of which is bananas. The research aims to determine the effect of various types and concentrations of banana extract on Phalaenopsis amabilis root induction by in vitro. The research was conducted in Laboratory of Tissue Culture Alifa Agricultural Research Center (AARC), Medan, North Sumatera, from May until July 2020. The research used a Factorial Completely Randomized Design (CRD) with 2 factors, the first factor was the type of banana extract with 3 levels, consisting of Ambon, Raja, and Kepok. The second factor is the concentration of banana extract (C) with 4 levels, consisting of 50 g/l, 100 g/l, 150 g/l, 200 g/l. The results showed that the concentration of banana extract had significant effect on the number of roots, but various types of bananas and the interaction of the types of bananas and concentration banana extract had no significant effect on root induction.

Kitchen Diet vs. Industrial Diets-Impact on Intestinal Barrier Parameters among Stroke Patients.

Background and aims: Strokes are the second highest cause of death in the world and the most common cause of permanent disability in adults. Intestinal barrier permeability thus contributes to diminished homeostasis within the body, which further affects the healing process and convalescence. Each stroke patient should be administered with ingredients that support the intestinal barrier (e.g., protein and fiber). The aim of this study was to compare the effect of various types of diet (enteral with or without fiber vs. a mixed kitchen diet) on the metabolic activity of intestinal microbiota, namely short chain fatty acids, and gut barrier integrity parameters (zonulin and calprotectin. Methods: Patients (n = 59), after suffering an ischemic stroke, were randomly allocated to three groups receiving: the kitchen diet (n = 32; 1.2 g fiber in 100 mL); Nutrison Energy® (n = 14; 0.02 g fiber in 100 mL); and Nutrison Diason Energy HP® (n = 13; 1.8 g fiber in 100 mL). The patients underwent anthropometric measurements and blood samples (for prealbumin measurements), and stool samples (for zonulin and calprotectin determinations) were taken twice, on admission and a week later. Results: Industrial diets enriched with fiber maintained nutritional status and had a beneficial effect on intestinal barrier permeability parameters. Patients fed with kitchen diets demonstrated a decreased number of lymphocytes, hemoglobin, erythrocytes, and increased serum concentration of C-reactive protein, but improved gut barrier markers. Proton pump inhibitors were shown to increase the inflammatory process in gut. Conclusions: Stroke patients should be administered with industrial diets enriched with fiber to improve gut barrier integrity and nutritional parameters.

Microwave‐Assisted Synthesis of 4‐Aryl‐1,4‐dihydropyridines as Potent Anticancer Agent and Their In‐Silico Studies

AbstractIn our effort directed toward the discovery of novel potent anticancer agents, a large library of novel 4‐aryl‐1,4‐dihydropyridines (23‐58) with heterocyclic ring at 4, position of aryl group has been synthesized through Hantzsch synthesis. These synthesized hybrids have been well characterized and evaluated for their cytotoxic activities against a panel of human cancer cell lines viz. EAC, HEK, and MCF cell lines by MTT assay. The cytotoxic activity has been revealed by the effects of various types of substituent present on the dihydropyridine ring. All the synthetics (23‐58) have shown good potency against EAC cell line. However, compounds 36, 40, 42, and 54 have displayed significant inhibitory potential against both EAC and MCF‐7 cell lines. In addition, these promising analogues have been selected for their molecular docking studies against 5TVQ protein to know the binding affinity which was identified to be a plausible target site. Compound 42 has exerted the highest inhibition effect on cancerous cells and more potency than the reference drug, doxorubicin even at low concentration (1μg/ml) and showed non‐toxicity to human normal cells suggesting high safety to normal cells. Compound 42 has also shown the highest docking score and inhibition constant which could be regarded as convincing lead for further clinical pursuit.

This study was conducted to determine the effect of various types of growing media on the proliferation of arbuscular mycorrhizal fungi using mung bean host plants. This research was conducted at the Greenhouse, Faculty of Agriculture, Universitas Muslim Indonesia, and the Laboratory of Microbiology, Research, and Development Center for Environment and Forestry. The study started from April to August 2021. This study was compiled based on a completely randomized design consisting of four treatments of growing media, namely: soil, soil + raw husk, soil + husk charcoal, and soil + raw husk + husk charcoal. Each treatment was repeated 3 times so that 12 experimental units were obtained, and each experimental unit used 3 polybags so that there were 36 polybags in all. The results showed that the difference in planting media had an effect on the proliferation of arbuscular mycorrhizal fungi. Soil growing media obtained the highest arbuscular mycorrhizal fungal infection, namely 76.11%, and the number of spores, 49.33. The growth of the host plant (mung bean) was better in soil + husk charcoal as indicated by the number of leaves of 17 pieces, a root length of 37.66 cm, and a root volume of 2.33 ml.

Effects of feeding systems on yield and performance of Linda geese (Anserinae sp.) in hot climatic conditions

This study evaluated the effects of various types of feeding on fattening period and performance of Linda geese. Feeding patterns consisted of concentrate feed-based intensive and pasture feed-based semi-intensive. A total of 150 goslings aged three days were divided into two groups, each consisting of three replications. All groups were given rations containing 23% crude protein and 3100 kcal/kg ME in weeks 0–6, and rations containing 20% crude protein 3100 kcal/kg ME between weeks 7 and 17. After the seventh week, the feed for the semi-intensive group was diluted with 20% barley and from the tenth week, this group started to graze on pasture. Live weight gain of the two groups was similar, although geese kept indoors consumed more concentrate. Feed protein digestion of geese was similar in the two feeding types. Digestion-related visceral weight in the pasture-supplemented group increased, whereas carcass weight decreased. Growth curves were used to estimate the age of Linda geese to the end of the fattening period. The average slaughter age was the fourth and fifth months, as indicated by Von Bertalanffy, Logistic, and Gompertz growth models, which used the data from the third week. Concentrate feeding enabled Linda geese to reach earlier higher slaughter weight, although it was not considered economical. Although averages of bodyweight gain over the trial appeared slightly better in the concentrate-based intensive group, the results revealed that concentrate feed supplement and pasture may be the best and most economical form of feeding for Linda geese.

Detecting Differences in the Impact of Construction Land Types on Carbon Emissions: A Case Study of Southwest China

The area with the highest concentration of carbon emission activities is construction land. However, few studies have been conducted that investigated the different effects of various types of construction land on carbon emissions and the extent of their impact. To address this shortcoming, this study constructed a multi-indicator evaluation system with 393 counties in Southwest China and integrated ordinary least squares and spatial regression models to deeply analyze the different impacts of construction land types on carbon emissions. The results revealed that (1) in Southwest China, carbon emissions were generally distributed in clusters, with significant spatial variability and dependence; (2) the distribution of urban land scale, rural settlement land scale, and other construction land scale all showed obvious spatial clustering differences; (3) all three types of construction land’s effect on carbon emissions was positive, and the direction of impact was in line with theoretical expectations; and (4) the other construction land scale had the highest effect on carbon emissions, followed by rural settlement land scale, while the urban land scale was slightly lower. The findings help to further explain the different impacts of construction land types on carbon emissions and provide theoretical references for the government to formulate more refined emissions reduction policies.

Structural damage identification considering uncertainties based on a Jaya algorithm with a local pattern search strategy and L0.5 sparse regularization

This study develops an improved Jaya algorithm for structural damage identification considering various uncertainties using vibration data. Most studies consider uncertainties, such as measurement noise, modeling uncertainties, and temperature variations separately but few on their coupling effects. On the other hand, the Jaya algorithm may trap local minimums in optimizing complex objective functions. Therefore, a novel modified Jaya algorithm is developed by integrating the one-step K-means clustering, Hooke–Jeeves pattern search, and linear population reduction strategies. The three modification strategies greatly improve the global optimization performance of the standard Jaya algorithm, which is verified by a series of high-dimension test functions. An L0.5 regularization is applied to improve the ill-posedness of the damage identification problem and ensure the sparsity of the solution. Numerical and experimental studies on two structures show that the proposed algorithm can identify the structural damage accurately, even considering the coupling effects of various types of uncertainties.

Measurement of Photosynthetic Pigment Content using Convolutional Neural Network

Estimation of photosynthetic pigment levels from leaves can be done using conventional methods using laboratory equipment such as spectrophotometers and using digital image processing from leaf images with a computational model. In digital image processing methods, various models are used, such as neural network, CNN, and linear regression. Measurement of photosynthetic pigment levels using image processing methods uses color value data from image data as input to the model used. In this study, we will analyze the effect of various types of color space and inpaint preprocessing settings on the accuracy of the CNN model in measuring leaf photosynthetic pigment levels. The color space types being tested are 4 single color spaces RGB, HSV, LAB, and YCbCr, as well as 6 color combination spaces RGB+HSV, RGB+LAB, RGB+YCbCr, HSV+LAB, HSV+YCbCr, and LAB+YCbCr. The choice of the type of color space takes into account the phenomenon of color constancy and the characteristics of the color space on the lighting elements. In addition, image data is divided into two types, namely through inpaint preprocessing and not, so that in total there are 20 types of input data. After the CNN model training process with various types of color spaces and different preprocessing settings as input data, observations were made on the accuracy values, namely the training MAE and the validation MAE for each model. From 20 types of input data, 3 types of input data are obtained which are recommended as input data that provide the best model accuracy value based on MAE validation with values ​​of 0.08761, 0.09252, and 0.09288. The three recommended input data from the sequence of accuracy values ​​are RGB+LAB without inpaint, RGB with inpaint, and LAB+YCbCr without inpaint.

Interventions to Reduce Opioid Prescriptions following Urological Surgery: A Systematic Review and Meta-Analysis.

Opioid prescriptions after surgery are major contributors to the opioid abuse epidemic. Several measures designed to limit opioid prescriptions at discharge have been evaluated. We conducted a comprehensive review and meta-analysis of the effectiveness of various types of interventions in reducing opioid prescriptions after urological surgery. A systematic review including MEDLINE®, Web of Science™ and Cochrane databases was conducted to identify studies on opioid prescriptions and urological surgery. Twenty-two studies met the inclusion criteria, of which 19 were used for quantitative analysis for reduction in opioid prescriptions. Additional outcomes included opioid consumption and satisfaction with analgesia. Of the 8,318 patients, 53% were in the pre- and 47% in the post-intervention cohort. Overall mean reduction/patient in prescribed opioids was -67.59 (95% CI 54.23 to 80.94) morphine milligram equivalents (MME). Direct interventions, implemented by providers within their local department or hospital, were more effective in reducing prescribed opioids compared to indirect, or systemic, interventions, at -76.68 MME (95% CI 60.04 to -93.31) vs -46.72 MME (95% CI 24.20 to -69.23; p=0.04). Opioid consumption significantly decreased post-intervention with a mean reduction of -18.31 MME (95% CI 7.89 to 28.72). Patient satisfaction with analgesia remained unchanged between the pre- and post-intervention groups. Successful reduction in opioid prescriptions, without compromising pain control, can be achieved through a variety of interventions. Direct interventions appear to have a greater impact than indirect interventions in reducing opioid prescriptions. Despite the reduction, unused, excess prescription opioids were still noted, which provides an opportunity for further control on opioid prescriptions.

Multi-dimensional "projection" - the impact of abiotic stresses on the content of seven active compounds and expression of related genes in Glycyrrhiza uralensis Fisch

Triterpenoids and flavonoids from licorice ( Glycyrrhiza uralensis Fisch.) are known to have a wide range of applications in the pharmaceutical, skin care, and food industries. The effects of various types of abiotic stresses and associated phytohormones - polyethylene glycol, sodium chloride, ultraviolet, cadmium, abscisic acid, and methyl jasmonate - on both the content of these secondary metabolites and the transcript levels of genes encoding enzymes of important biosynthetic pathways were evaluated in hydroponic seedlings of G. uralensis . In these treatments, abscisic acid induced a substantial increase in the levels of the four active compounds, compared to the control. Analysis of the expression of genes involved in the biosynthetic pathways of these compounds, such as FPPS , showed that their transcript levels were significantly up-regulated in the four stresses. These findings suggested that the multi-stress superposition pattern of the content of active compounds and the gene expression of their biosynthetic pathways may provide insights to explore the management of secondary metabolite synthesis pathways in medicinal plants. It could facilitate a better understanding of the formation patterns of active compounds in licorice in artificial cultivation. Further insights may also be provided to increase the yield of these high value components. • Exogenous abscisic acid has a positive effect on the active compounds of licorice. • Glycyrrhizic acid-related gene expression was uprated in PEG and UV treatments. • Hydroponic system can be used to study the effect of abiotic stresses on licorice. • Multi-stress has potential in regulation and production of secondary metabolites.

Induction of Heme Oxygenase-1 by 15d-Prostaglandin J2 Mediated via a ROS-Dependent Sp1 and AP-1 Cascade Suppresses Lipopolysaccharide-Triggered Interleukin-6 Expression in Mouse Brain Microvascular Endothelial Cells.

Heme oxygenase-1 (HO-1) has been shown to exert antioxidant, anti-inflammatory, and anti-apoptotic effects in various types of cells. Therefore, the induction of HO-1 is an excellent rationale for the development of protective drugs. 15-Deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2) can modulate the expression of antioxidant defense proteins and be beneficial for neuroinflammation. Brain endothelial cells play an important role in the pathophysiology of brain disorders. Whether 15d-PGJ2 can induce HO-1 expression and protect against the inflammatory responses in mouse brain microvascular endothelial (bEnd.3) cells remains unclear. Here, we reveal that 15d-PGJ2 stimulated HO-1 protein and mRNA expression in a time- and concentration-dependent manner in bEnd.3 cells, which was attenuated by diphenyleneiodonium chloride (DPI) and MitoTempo. Thus, activation of NADPH oxidase (NOX)- and mitochondria-derived reactive oxygen species (ROS) mediated 15d-PGJ2-induced HO-1 expression. ROS generation could cause phosphorylation of protein kinase C (PKC)δ, leading to HO-1 expression, which was suppressed by Rottlerin (selective inhibitor PKCδ), DPI, and MitoTempo. We further demonstrated that phosphorylation of c-Jun N-terminal kinase (JNK)1/2 participated in 15d-PGJ2-upregulated HO-1 expression, which was blocked by SP600125 or Rottlerin. Moreover, 15d-PGJ2-induced HO-1 expression was mediated through the activation of c-Jun (a subunit of activator protein 1 (AP-1)) and specificity protein 1 (Sp1), leading to their interaction with the HO-1 promoter, revealed by chromatin immunoprecipitation assay, which was attenuated by SP600125, Mithramycin A, or Tanshinone II A. We further verified the anti-inflammatory effect of HO-1 expression. Our results showed that 15d-PGJ2-induced HO-1 could mitigate the lipopolysaccharide-triggered interleukin-6 expression and secretion, as measured by an ELISA assay kit. These results suggest that 15d-PGJ2-induced HO-1 expression is mediated through the activation of NOX- and mitochondria-derived ROS-dependent PKCδ/JNK1/2/Sp1 and the AP-1 signaling pathway and protects against inflammatory responses in bEnd.3 cells.

Application of the Data Envelopment Analysis method to assess the efficiency of social and economic systems


 
 
 
 The article deals with the relevant scientific and practical task – assessing the effectiveness of various types of existing systems by methods of mathematical modeling. In particular, the research investigates the efficiency of functioning of social and economic systems using nonparametric methods of mathematical modeling. For the verification of the results, the research uses the Data Envelopment Analysis (DEA), which is a modern method based on the creation of the efficiency limit. The article considers in detail the theoretical foundations of the DEA method, which is based on the problems of mathematical programming, namely, the problems of linear programming. The article presents main theoretical models of this nonparametric method for input and output and analyzes the technique of its application. As an example of the practical use of this method, the research suggests the analysis of the demographic situation in the regions of Ukraine based on the main demographic indicators – mortality and birth rate for a certain estimated period. In the process of analyzing the results of modeling, the research has identified two groups of regions – one with the most effective indicators of the demographic situation, and the second – with the least effective indicators. The selected groups of regions are invariant when using different models of the method. The calculations obtained in the process of modeling confirm the real condition of the demographic situation in the regions of Ukraine, which is characterized by the actual statistical indicators of the population in regions. For each region, the research has established reference regions, which in their structure are similar to the structure of indicators of given regions and are a certain model and reference point for the practical improvement of the demographic situation. The recommended values of indicators that set the direction of improving the demographic situation in each specific region of Ukraine have also been calculated during the research.
 
 
 

Effect of various types and doses of biochar on hybrid maize growth

Climate change also has an impact on agriculture, especially at Mediterranean red-yellow soil which is characterized with low fertility. The application of biochar is an alternative to increase soil fertility, as well as promoting the growth and yield of maize in red-yellow Mediterranean soil. The study aimed it determining the appropriate type and dose of biochar in red-yellow Mediterranean soil to support the growth of hybrid maize. The study used a factorial Randomized Completely Block Design (RCBD) with two factors. The first factor was the type of biochar which consisted of 3 levels, namely coconut shell biochar (B1), rice husk biochar (B2), and maize cob biochar (B3). The second factor was the dose of biochar which consists of 5 levels, namely 0 ton.ha−1 (D0), 5 ton.ha−1 (D1), 10 ton.ha−1 (D2), 15 ton.ha−1 ( D3), and 20 ton.ha−1 (D4). The analysis of variance (ANOVA) continued with the Duncan’s Multiple Range Test (DMRT) at level 5% were employed for data analysis. The results showed that the application of biochar had a significant effect on the growth of hybrid maize, especially on some observational variables. The application of biochar rice husks significantly affected the stem diameter, leaves number, and dry weight of 7 week after plant (WAP). The dose of 15 tons.ha−1 significantly affected the dry weight of 4 WAP, while the interaction of rice husk biochar with a dose of 15 tons.ha−1 significantly affected the leaves width.

Biomechanical Analysis of the Influence of SACH Foot and Dynamic-Response Foot in Individual With Unilateral Transtibial Amputee During Running

Objective: Amputation of the lower limb due to loss of part of the musculoskeletal structure reduces performance and increases injury during locomotion. The effect of various types of prosthetic feet has been analyzed in several studies during running. The purpose of this study was a biomechanical analysis of the influence of SACH and Dynamic-Response foot on several kinetic variables in the stance phase of running in individuals with unilateral transtibial amputation. Materials & Methods: In this semi-experimental study, 8 left foot transtibial amputees were included in this study using an available or easy sampling method. The target population was unilateral transtibial amputees who were able to run and the available population included left transtibial amputees who were referred to Kosar Rehabilitation Center in Tehran from 2008 to 2012. To adapt to the foot, each foot was used by the subjects for at least one week before the experiment. All subjects participated in 3 running evaluation sessions; 1 session involving the use of their own foot (familiarization session), 1 session involving the use of SACH foot, and 1 session involving the use of Dynamic foot. Only data from the 2 last sessions were used to compare both feet. Each subject runs in 12-meter walkway 3 times at a speed of 2.5 meters per second. The same running speed was chosen for the comparability of kinetic variables. Sport shoes were used to bring the test conditions closer to the actual running conditions. In each session, 3 successful trials were performed so that the foot was in full and perfect contact with the force plate. Kistler force plate and three-dimensional motion analysis Vicon system were used to collect kinetic and kinematic data, respectively. The motion and the force plate data were sampled simultaneously at 200 and 1000 Hz, respectively. The trajectories of the markers and analog data were filtered using the predicted mean square error adaptive filter in version 1.7 of the Vicon software package. The Kinetic variables were generated using the dynamic model of the Vicon Plug-in-Gait. The vertical ground reaction force was normalized for body weight. In the present study, 5 variables were selected for biomechanical analysis of feet. The maximum vertical ground reaction force, power, spring efficiency, ankle moments at the amputated leg, and the symmetry ratio (percentage) of the maximum vertical ground reaction force between the amputated leg and the intact leg were calculated. All values ​​in each trial were averaged for each subject with each foot. A paired t-test and a Wilcoxon test were used to analyze the data based on normality (P ≤0.05). Results: In examining the normality of the data distribution, the results showed that the data of maximum power absorption of the ankle with the SACH foot and the maximum power absorption of the hip with the Dynamic-Response foot did not have a normal distribution and other variables had a normal distribution. The results of paired t-test and Wilcoxon showed that Spring Efficiency and Maximum Plantar Flexion were significantly different between the SACH and Dynamic-Response feet (P ≤0.05). The Spring Efficiency was greater with Dynamic-Response foot than the SACH foot (P =0.05), although the Maximum Plantar Flexion with the SACH foot was greater than Dynamic-Response foot (P =0.05). While there is no statistical difference between the maximum vertical ground reaction force, maximum power absorption and generation in the ankle, maximum power absorption and generation in the knee, maximum power absorption and generation in the hip, maximum dorsiflexion moment, and the symmetry ratio (percentage) of the maximum vertical ground reaction force between the amputated leg and the intact leg. Conclusion: The results of the study showed that the spring efficiency with Dynamic-Response foot was greater than SACH foot and closing to the spring efficiency of a normal foot. With this perspective, the Dynamic-Response foot has more natural performance than the SACH foot.

Parental Practice of Providing Care for their Infants Receiving Vaccination: Pilot Study

Providing effective health care for infants who receive immunization is very of a strong necessity for their health and safety. According to immunization can cause adverse effects in various types, which call as Adverse Events Following Immunization (AEFI). The AEFI usually can occur in various types such as skin rash and redness, fever, and pain. In case of severe side effects; anaphylactic shock may occur. Therefore, parents need to provide health care for their young children. This pilot study was aimed at studying how parents provide care for their infants about vaccination at one hospital in Thailand. Ten parents of infants were purposive selection. Data were collected by interview and observation with record form. Data analysis was done through content analysis and descriptive statistic methods. The findings displayed all parents took their infants for vaccination without checking the names and benefits of the vaccines. Two grandmothers gave medicine for relieving the fever of their infants both before and after vaccination. During vaccination, eight parents could not hold their infants appropriately. Five parents did not know how to support their infants during the injection. One grandmother relieved the fever of her infant by soaking in warm water mixed with limejuice. Two grandparents applied the balm and herbal medicated oil for relieving edema and pain at the injection area. Three grandparents applied herbal powder at the vaccinated area to decrease inflammation. All of them did not know of and thus did not observe AEFI events. Ultimately, the pilot study reflects the limitation of knowledge, beliefs, and practice among parents in relation to vaccination care for their infants. Thus, nurses and health personnel should create and provide family health education for enhancing relevant knowledge, beliefs, and skills for parents of infants.

Cross-Scale Study on Lime Modified Phosphogypsum Cemented Backfill by Fractal Theory

Pore structure is a critical factor affecting the strength characteristics of mine backfill materials. In this paper, based on the mechanical tests on lime modified phosphogypsum cemented backfill (LMPGCB), the microstructure of the LMPGCB sample was characterized by nuclear magnetic resonance (NMR) and scanning electron microscopy (SEM) imaging. Based on the fractal theory (FT), the values expressing the fractal characteristics of the NMR T2 spectrum and SEM images were determined. The mathematical model between the NMR-FT fractal dimension and the SEM-FT box dimension was developed to infer the overall pore characteristics from various pore characteristics. The functional relationships between the strength and pore content and dimension were established, and the effects of pore structure on the strength were discussed. The results indicate that: (1) in NMR-FT fractal dimension, the fractal effect of various types of pores is better. The fractal dimension of the small pore is between 0.86–1.38, in which the overall trend first decreases and then increases. (2) In the SEM-FT box dimension, the fractal effect of the overall pore is better. The overall trend of box dimension decreased first and then increased at each kind of magnification. Furthermore, with the increase of magnification, the box dimension decreases. (3) There is a linear direct proportional relationship between the SEM-FT box dimension and the fractal dimensions of NMR-FT of small pores. The relationship between SEM-FT box dimension and NMR-FT fractal dimensions of various types of pores conforms to the plane relationship. There is a linearly increasing relationship between dimension and pore content and a decreasing relationship between dimension and strength.
