Authors: Jahan Nusrat , Noor Rashed , Munshi Saurab Kishore
Published: August 2019

Green banana (Musa spp.) and papaya (Carica papaya), which are commonly consumed as vegetables, are fruits with lots of health benefits. Due to their various medicinal applications, both the fruits are likely to contain antimicrobial properties. In this regard, present study was undertaken to determine the microbiological quality as well as the anti-bacterial traits of fresh green banana and papaya. To serve the purpose, a total of 12 samples (6 green bananas and 6 green papaya) were collected from different local and super shops as well from cultivation land of some villages of Bangladesh. The samples contained the microbial contamination with viable bacteria and fungi up to 107cfu/g and 103 cfu/g. Among the pathogenic bacteria, Staphylococcus spp. Pseudomonas spp. and Vibrio spp. were predominant as found in most of the samples in average of 102 cfu/g. Whereas Escherichia coli, Salmonella spp. and Shigella spp. were totally absent in all the samples. On the other hand, Klebsiella spp. was present in same samples. Additionally, the anti-bacterial poverties of the samples were chalked out. The in-vitro antimicrobial activities of the ethanolic, methanolic and hot water extracts of the samples were noticeably found against all the tested bacteria. Overall, present study revealed that both the green fruit samples were highly contaminated although they have antimicrobial activities. Thus, consumers’ awareness on the risk of consuming pathogen contaminated vegetables needs to be re-awakened and further investigations are required for potential antimicrobial properties.

RETRACTED: Surgical Treatments for Canine Anterior Cruciate Ligament Rupture: Assessing Functional Recovery Through Multibody Comparative Analysis
Authors: Putame Giovanni , Terzini Mara , Bignardi Cristina , Beale Brian , Hulse Don , Zanetti Elisabetta , Audenino Alberto
Published: August 2019

Anterior cruciate ligament (ACL) deficiency can result in serious degenerative stifle injuries. Although tibial plateau leveling osteotomy (TPLO) is a common method for the surgical treatment of ACL deficiency, alternative osteotomies, such as a leveling osteotomy based on the center of rotation of angulation (CBLO) are described in the literature. However, whether a CBLO could represent a viable alternative to a TPLO remains to be established. The aim of this study is to compare TPLO and CBLO effectiveness in treating ACL rupture. First, a computational multibody model of a physiological stifle was created using three-dimensional surfaces of a medium-sized canine femur, tibia, fibula and patella. Articular contacts were modeled by means of a formulation describing the contact force as function of the interpenetration between surfaces. Moreover, ligaments were represented by vector forces connecting origin and insertion points. The lengths of the ligaments at rest were optimized simulating the drawer test. The ACL-deficient model was obtained by deactivating the ACL related forces in the optimized physiological one. Then, TPLO and CBLO treatments were virtually performed on the pathological stifle. Finally, the drawer test and a weight-bearing squat movement were performed to compare the treatments effectiveness in terms of tibial anteroposterior translation, patellar ligament force, intra-articular compressive force and quadriceps force. Results from drawer test simulations showed that ACL-deficiency causes an increase of the anterior tibial translation by up to 5.2 mm, while no remarkable differences between CBLO and TPLO were recorded. Overall, squat simulations have demonstrated that both treatments lead to an increase of all considered forces compared to the physiological model. Specifically, CBLO and TPLO produce an increase in compressive forces of 54% and 37%, respectively, at 90° flexion. However, TPLO produces higher compressive forces (up to 16%) with respect to CBLO for wider flexion angles ranging from 135° to 117°. Conversely, TPLO generates lower forces in patellar ligament and quadriceps muscle, compared to CBLO. In light of the higher intra-articular compressive force over the physiological walking range of flexion, which was observed to result from TPLO in the current study, the use of this technique should be carefully considered.

Acupuncture and Ergonomic interventions in the management of carpal tunnel syndrome among industrial workers- Case studies
Authors: Shokunbi Ganiyu Oluwaleke
Published: August 2019

SummaryBackground:  There are several studies on carpal tunnel syndrome (CTS), but despite this, considerable uncertainties and controversies exists on prevention, appropriate strategies and outcome of various treatment methods. The efficacy of ergonomic job analysis and acupuncture in the prevention and treatment of mild to moderate CTS among industrial workers appears not to have been widely investigated.Objectives: These case studies assessed the short-term effects of acupuncture treatment and application of ergonomic job analysis in the management of carpal tunnel syndrome among industrial workers.Methods: Subjects for this study were three industrial workers with a diagnosis of CTS of more than 3 months duration. Ergonomic work analysis was carried out to analyze and prescribe corrective measures for musculoskeletal and postural load in the subjects’ area of works. In addition to ergonomic job intervention, subjects underwent acupuncture treatment twice weekly for 8 weeks. The clinical symptoms of CTS was assessed using global symptom score (GSS) at baseline and at 8 weeks (after the intervention). Thus the main outcome measures used were GSS scores and ergonomic job analysis worksheet.Results:   All the subjects in this study completed the 8 week intervention and were evaluated for pain, weakness, numbness and frequency of wakening up at night and Paresthesia.  The 3 subjects showed improvement with recovery from symptoms at the end of treatment at 8 week. Two of the three participants reported more than 80% reductions in pain intensity while one of the three reported complete recovery (100%) from pain. Numbness and paraesthesia were reportedly reduced by not less than 50% at the end of 8 week treatment in all the subjects. One of the participants recorded 85% (highest) reduction in the overall GSS scores while another recorded 75% reduction (lowest) at the end of 8 week treatment. Two of the three participants also showed complete recovery from the weakness in hand grip strength due to CTS. Frequency of wakening up at night was reduced to zero in all the three participants. Conclusions: Findings from this study indicated that the acupuncture and application of ergonomic job analysis improved the overall symptoms of carpal tunnel syndrome among industrial workers suffering with CTS.KEYWORDS: Acupuncture, Carpal Tunnel Syndrome, Ergonomics, Global Symptom Score, Physiotherapy

Factors affect the carrying capacity of non-woven shopping bags
Authors: LAI-LI WANG , XUE-MEI DING , XIONG-YING WU
Published: August 2019

The belief that shopping with reusable shopping bags is an important environmental and socially conscious choice has
gained prevalence. Many countries have taken steps to ban free retail use of disposable plastic bags. Non-woven
shopping bags were widely used by consumers to carry purchased groceries and goods after prohibiting the distribution
of free plastic shopping bags in China since June 1, 2008. Carrying capacity is an important factor that affects the
reusable times of non-woven shopping bags. In this paper, the carrying capacity was evaluated with hanging tests. The
results showed that handle belt and the seam jointing handle belt and bag body fatigued faster than other parts during
tests. They were the most important two factors that affect the carrying capacity. Thermal attachment technology was
better than sewing technology as it caused less cutting damages on the fabric during the production of non-woven
shopping bags. Increasing the width of handle belts and the gram weight of non-woven fabric can improve the carrying
capacity of shopping bags.

Social factors associated to the multiple risk behaviors among high school students: A case study of Hanoi high school students, Vietnam
Authors: Huong Duong Thi Thu
Published: August 2019

Background: Young people who engaged in different risk behaviors attracted concern nowadays. Noticeably, the concurrent multiple risk behaviors generate adverse effect to health and their future life. Aims: The objectives of this study were to investigate the prevalence of the concurrent multiple risk behaviors and to evaluate the association between social factors and the concurrent multiple risk behaviors among the high school students in Hanoi, Vietnam. Methods: A quantitative survey with a cross sectional design was applied involving a total of 1,333 Hanoi high school students. The survey was conducted in the end of 2016. The multivariate linear regression models were applied to examine the social factors associated with the concurrent multiple risk behaviors of Hanoi high school students. Eighteen different risk behaviors had been selected for constructing a composite variable of the total risk behaviors that students have engaged in. Results: On average, the high school students have been reported involving in 4.88 behaviors of the 18 selected observed risk behaviors. The multivariate linear regression models with demographic factors and different social connections of high school students could explain for about 37.6% of the difference in composite variable of the total risk behaviors. This present study reveals several factors that increase the number of risk behaviors the students may engage, including the connection to the family's members or friends, duration in social media, and the number of friends in the online network. In the contrast, strong family connection has been demonstrated to provide a "safe haven" for protecting the high school students from involving in increasing multiple different risk behaviors. Conclusion: The research findings strongly recommend early prevention strategies should be conducted among the high school students. The identified concurrent risk behaviors should be targeted as prevention actions rather than focusing on controlling individual risk behaviors. In addition, the involvement of their parents and friends are suggested to be the target audience together with students in concurrent risk behaviors controlling and preventing programs among the high school students and young generation.

By the integrated use of the Classical Grounded theory, the Procedure Grounded Theory and the Construction Grounded Theory, it adopted the normative research process of open coding, axial coding and selective coding to refine 34 concept—multi-node interactive, cross-level coupling relationship, etc, and formed 11 fundamental categories which include platform leadership power, network organization entrepreneurial mode, etc. Then, we analyzed the interactions between categories, based on which, a double-level and three-type-characteristics model were ultimately built. The study was finished by both two methods of statistical software and manual operation. In order to improve the reliability and validity of the study, it invited another coder to test the category subordination collaboratively, and used matched group to test the theoretical saturation.

This paper studies the volatility spillover and dynamic correlation between EU emission allowance (EUA) prices and energy prices by considering three energy commodities, including oil, gas, and coal. The asymmetric BEKK model is employed for multi-phase analysis of EU ETS, yet only a little empirical evidence backing up the existence of volatility spillover between EU ETS and energy markets, i.e., the establishments of the EU ETS may not effectively limitation and influence energy markets. The time-varying conditional correlation between EUA and each of energy prices is analyzed. The dynamic correlation shows there is a relatively stable, positive correlation between the EUA and Brent oil, natural gas. However, modeling the dynamics correlation also suggests that the correlation between the EUA and the natural gas, coal became weaker and more volatile since second and third phases, especially after the Global Financial Crisis in 2008, which may indicate that the demand reduction in emission allowances caused by the economic slowdown far exceeds the reduction in the annual restraint of EU ETS.

Published: August 2019

Machine-learning (ML) algorithms will play a crucial role in studying the large data sets delivered by new facilities over the next decade and beyond. Here, we investigate the capabilities and limits of such methods in finding galaxies with brightness-variable active galactic nuclei (AGNs). Specifically, we focus on an unsupervised method based on self-organizing maps (SOM) that we apply to a set of nonparametric variability estimators. This technique allows us to maintain domain knowledge and systematics control while using all the advantages of ML. Using simulated light curves that match the noise properties of observations, we verify the potential of this algorithm in identifying variable light curves. We then apply our method to a sample of ∼8300 WISE color-selected AGN candidates in Stripe 82, in which we have identified variable light curves by visual inspection. We find that with ML we can identify these variable classified AGN with a purity of 86% and a completeness of 66%, a performance that is comparable to that of more commonly used supervised deep-learning neural networks. The advantage of the SOM framework is that it enables not only a robust identification of variable light curves in a given data set, but it is also a tool to investigate correlations between physical parameters in multidimensional space—such as the link between AGN variability and the properties of their host galaxies. Finally, we note that our method can be applied to any time-sampled light curve (e.g., supernovae, exoplanets, pulsars, and other transient events).

Authors: Sriyanti Roza , Mose Johanes C. , Masrul Masrul , Suharti Netti
Published: August 2019

BACKGROUND: Preeclampsia can be divided into early (EOPE) and late (LOPE) onset preeclampsia. Preeclampsia is related to the failure of placentation. Accumulation of hypoxia-inducible factors (HIF)-1α is commonly an acute and beneficial respond to hypoxia, while chronically elevated is associated with preeclampsia.
AIM: This study aims to evaluate the serum levels of HIF-1α in preeclampsia and normal pregnancy, and to compare the difference between early-onset and late-onset preeclampsia.
METHODS: A cross-sectional comparative study was conducted among a total of 69 pregnant women at ≥ 20 weeks of gestation, were recruited at obstetrics and gynaecology department at Dr M. Djamil Padang Hospital, network hospitals, health centres. They were divided into three groups early-onset preeclampsia, late-onset preeclampsia, and normal pregnancy. Preeclampsia was diagnosed using International Guidelines. Data were analysed by SPSS 24 program; data are presented as median and range or as mean ± standard deviation. One-way ANOVA test was used to determine the relationship between HIF-1α levels with the onset of preeclampsia.
RESULTS: The results showed that the mean maternal serum HIF-1α levels in early-onset preeclampsia (EOPE), late-onset preeclampsia (LOPE), and normal pregnancy were 1366.96 ± 733.40 pg/ml, 916.87 ± 466.06 pg/ml, and 716.77 ± 541.08 pg/ml. Serum HIF-1α levels were higher in early-onset preeclampsia (EOPE), and late-onset preeclampsia (LOPE) compared to normal pregnancy. Among preeclampsia patients, serum HIF-1α was higher in EOPE than LOPE women. Statistical analysis revealed a significant difference in mean maternal serum HIF-1α between early-onset preeclampsia, late-onset preeclampsia, and normal pregnancy (p < 0.05).
CONCLUSION: This study concluded that there is a significantly different level of HIF-1α between in early-onset preeclampsia, late-onset preeclampsia and normal pregnancy. Early-onset preeclampsia is the highest levels of serum HIF-1α.
Neo Adjuvant Chemotherapy on Testicular Cancer after Scrotal Exploration: A Case Report
Authors: Novianda Andhika Hernawan , Prapiska Fauriski Febrian
Published: August 2019

BACKGROUND: A case of testicular cancer treated with neo adjuvant therapy in a patient in male is rare. When testicular cancer presents, it is usually directly operated due to the size of cancer which presented within the order of operable size.
CASE PRESENTATION: Here, we report a rare case of a 5-year-old male patient presented to the emergency room (ER) due to mass on the scrotum without the difficulty of urination. From clinical findings, mass with a size of 15 x 10 cm was found with multiple abscesses on both sides of the scrotum. Pathological Anatomy Examination confirmed yolk sac tumour present within the scrotal mass. Initially, palliative chemotherapy took place to reduce the growth rate of the tumour. However, due to the responsiveness of testicular cancer to chemotherapy drugs, it reduced into operable size testicular cancer. Wide excision and Orchidectomy was then performed, followed by adjuvant chemotherapy.
CONCLUSION: This case report showed the possibility of using neo adjuvant chemotherapy as an alternative treatment when inoperable testicular cancer presented in hospital.

Published: August 2019

BACKGROUND: Despite the high prevalence of rheumatic mitral stenosis (MS) in Indonesia, the impact of aging on the anatomical and hemodynamic component of rheumatic MS is not well studied.
AIM: To analyze the association of age with various echocardiographic parameters in patients with isolated severe rheumatic MS in Indonesia.
METHODS: A cross-sectional study was conducted enrolling 263 subjects with isolated severe rheumatic MS who underwent transthoracic echocardiography (TTE) during January 2015 until December 2017 at National Cardiovascular Center of Harapan Kita, Jakarta, Indonesia. Demographic data were collected, and echocardiographic variables were measured based on standard TTE examination using GE Vivid 7 and S6 Doppler Echocardiography System (GE Medical System, Norway).
RESULTS: Of 263 subjects, there are 84 men and 179 women aged 18-80 (mean age 42.9) years old. Most patients had atrial fibrillation (80%), with a higher prevalence of AF in the older group. Age was positively correlated with LA diameter and Wilkin’s score (r = 0.186, P = 0.002; r = 0.142, P = 0.022; respectively); while mean MVG (r = -0.304, P < 0.001), TR Vmax (r = -0.126, P = 0.04), TR maxPG (r = -0.127, P = 0.039) and TAPSE (r = -0.125, P = 0.044) were correlated negatively with age. Mean MVG has the strongest correlation with age in our subjects.
CONCLUSION: This is the first study in Indonesia that analyze the association of age and different echocardiographic parameters in isolated severe rheumatic severe MS patients. Age has a significant correlation with mean MVG, LA diameter, Wilkin’s score, TR Vmax, TR maxPG, and TAPSE. We assume that the association of age and these parameters were influenced by the normal aging process and progression of chronic MS.

BACKGROUND: Exposure to cigarette smoke may stimulate the inflammatory response and activate polymorphonuclear leukocytes, thus resulting in secretion of cellular proteases. Vitamin D has the potential to modulate the inflammatory response to harmful particles in patients with Chronic Obstructive Pulmonary Disease (COPD).
AIM: This study aimed to determine the levels of vitamin D, MMP-9, and TIMP-1 in COPD subjects, healthy smokers and nonsmokers of Indonesian citizens
METHODS: Seventy-eight male subjects took part in this study. They comprised three groups, i.e. COPD (n = 26), healthy smokers (n = 25) and healthy non-smokers (n = 27). Serum 25(OHD) levels, MMP-9, and TIMP-1 concentrations measured by electrochemiluminescence binding assay (ECLIA) and enzyme-linked immunosorbent assay (ELISA).
RESULTS: The levels of vitamin D in COPD (21.96 ± 6.62ng/mL) and healthy smokers (27.87 ± 7.08 ng/mL) were significantly (p < 0.001) lower compared to that in healthy non-smokers (31.71 ± 9.24 ng/mL). On contrary, the levels of MMP-9 in COPD (11.98 ± 41.54 ng/mL) was significantly (p = 0.003) higher compared to that in healthy smokers (2.23 ± 3.39 ng/mL) and healthy non-smokers (0.89 ± 1.12 ng/mL). Whereas the levels of TIMP-1 in healthy smokers (24.64 ± 57.77 ng/mL) was significantly (p < 0.001) lower compared to that in COPD (58.40 ± 77.53 ng/mL) and healthy non-smokers (46,54 ± 71,48 ng/mL).
CONCLUSION: The present study showed the lowest level of vitamin D, the highest level of MMP-9 and TIMP-1 in the COPD subjects.
