Background: Infantile hemangioma (IH) is the most common benign tumor in infancy. Most IHs resolve spontaneously and do not require treatment. Therapeutic intervention is necessary for life-threatening IH, tumors posing functional risks, ulceration, and severe anatomic distortion, especially on the face. Beta-blockers, most specifically propranolol, have been shown to induce involution of IH, which should be administered as early as possible to avoid potential complications. Purpose: To report a case of IH with visual impairment treated successfully using oral propranolol. Case: A 4-month-old girl weighing, 6.3 kg, with redness plaques on the right face since 3 weeks after birth. The lesions rapidly increased in size within 2 months, and the lesions on her right eyelid made it difficult to open her right eye. Dermatological examination showed erythematous plaques, compressible and varying in size and ptosis. The patient was diagnosed with periocular infantile hemangioma and was given oral propranolol therapy with an initiated dose 3x1 mg. The dose was increased gradually. The lesions were significantly decreased and she could open her right eye normally after 5 months of propranolol therapy. Discussion: Some cases of IH require early treatment. Early treatment is indicated for IH causing functional impairment. The use of propranolol in the management of IH is very effective in the reduction of the lesions and Has minimal side effects. Conclusion: Early diagnosis and intervention with propranolol for IH play an important role in determining the optimal outcomes.

The effect of nitrogen-based ion implantation on the characteristics of 316l stainless steel for implant materials has been performed. This study aims to determine the effect of variations in implantation energy on the characteristics of the surface mechanical properties, density, and corrosion resistance of 316L stainless steel. The 316L stainless steel plate was implanted with nitrogen ions with an optimum dose of 5 x 1016 ions/cm2 for various implantation energies of 70, 75, 80, 85, and 90 keV. The implanted samples were then characterized by density, hardness, corrosion resistance, and microstructure tests using SEM-EDX. The test results showed an increase in hardness and corrosion resistance in pieces implanted with nitrogen ions and reached the optimum point at an implantation energy of 80 keV. This was also supported by the results of the SEM-EDX analysis, which showed an addition of nitrogen content from the maximum limit of the ASTM 2000 standard for 316L stainless steel of 0.1% to 2.2%. Whereas in the density test, the density of the material tends to be constant at the energy variations carried out but has increased after implantation.

Authors: Thongkam Thinikan , Hemavibool Khuanjit
Published: December 2022

This study presents a simple method for determination of potassium in microliter scale using a paper device together with a smartphone. The method begins with the ion-pair extraction of dibenzo-18-crown-6-K+ complex into dichloromethane with an excess amount of calmagite. The aqueous phase containing the remaining calmagite is transferred to the paper device, where a smartphone is used to capture the color and convert to RGB value. The linear detection range was found to cover potassium concentrations from 20 mg L-1 to 120 mg L-1. The detection and quantification are 5.41 mg L-1 and 18.03 mg L-1, respectively. Potassium detection was carried out in a variety of actual soil samples, and the results were validated against spectrophotometric results using a paired t-test, which indicated high accuracy. The proposed method is simple, fast, and inexpensive, and it requires no complicated equipment, making it ideally suited for detection of potassium in soil.

Published: December 2022

Location information of the object based on wireless communication will play crucial role in several Wireless Sensor Network (WSN) applications. Some applications need to know the exact position of the object. The advantages of Zigbee as the part of Radio Frequency (RF) technology such as low cost, high scalability, high availability, and supporting topology for Indoor positioning system (IPS). In this paper, we propose IPS using Received Signal Strength Indicator (RSSI) based Zigbee protocol. The proposed approach is based on the enhancement of Trilateration algorithm. Basically, the main concept of the conventional trilateration is using three strongest RSSI from references node. However, the instability from measured RSSI influenced to its estimation result. Therefore quadratic weighted is adding to this proposed scheme as the enhanced trilateration algorithm. The estimated distance output from conventional trilateration algorithm will be used for calculating the weighted value and multiplying to each the reference node which produced lower estimation error. The simulation result show that using enhanced trilateration algorithm has capability to improve accuracy of estimated position up to 90.55 % with mean square error (MSE) 2.03 meters compared with only using conventional trilateration reached high estimated error up to 4.31 meters.

Published: December 2022

Altered expression of microRNAs (miRNAs) after spinal cord injury (SCI) has been described as being responsible for the main secondary responses, such as apoptosis. X-linked inhibitor apoptosis protein (XIAP) is a key apoptotic component involved in the progression of apoptotic programmed cell death. Several regulators have been described to modulate the XIAP's function, including the post-transcriptional regulator's miRNAs. The main aim of the present work is to identify miRNAs with altered expression after SCI which can regulate XIAP expression using bioinformatics and prediction algorithms. Our bioinformatic analyses identified several miRNAs candidates whose up-regulation following SCI could be responsible for the down-regulation of XIAP, including miR-199a-5p. We examined the relationship between miR-199a-5p and XIAP and their negative correlation expression levels after SCI and characterized the spatial distribution of miR-199a-5p in uninjured and rat-contused spinal cords, using a specific fluorescent in situ hybridization (FISH) probe for miR-199a-5p. Finally, in vitro simulation of the increment in miR-199a-5p observed after SCI by transfection of a miR-199a-5p mimic into C6 cells confirmed the decrease in XIAP protein levels.. These findings provide new insights into apoptotic miRNAs-mediated mechanisms after SCI, which will help us develop therapeutic strategies based on miRNAs for treating SCI.
The Financial Toxicity of Advanced Hepatocellular Carcinoma Treatment in Low Middle-Income Countries
Authors: Omar Nabil Elhadi
Published: December 2022

Advanced Hepatocellular carcinoma (HCC) is no longer a terminal illness. This change was mainly attributed to the development of new treatments including tyrosine-kinase inhibitors (TKIs), vascular endothelial growth factor (VEGF) inhibitors and immune checkpoint inhibitors (ICPIs) but the financial toxicity of treating advanced HCC is of a major concern specially in low middle-income countries (LMICs) where the patients are still battling for their most basic rights. Most of advanced HCC patients in LMICs have very limited accessibility to the new treatments including ICPIs. Searching for out of the box solutions to improve access to treatments -mainly ICPIs- is an utmost necessity for LMICs advanced HCC patients.
Adsorbed Oxygen Ions and Oxygen Vacancies; Their Concentration and Distribution in Metal Oxide Chemical Sensors and Influencing Role in Sensitivity and Sensing Mechanism
Authors: Ciftyürek Engin , Li Zheshen , Schierbaum Klaus
Published: December 2022

Oxidation reactions on semiconducting metal oxides (SMOs) surfaces have been extensively worked on in catalysis, fuel cells, and sensors. SMOs engaged powerfully in energy-related applications such as batteries, supercapacitors, solid oxide fuel cells (SOFCs), and chemical gas sensors. The deep understanding of SMO surface and oxygen interactions and defect engineering has become significant because all those mentioned applications are based on the adsorption/absorption and consumption/transportation of adsorbed (physisorbed-chemisorbed) oxygen.

More understanding of adsorbed oxygen and oxygen vacancies (〖V_O^•,V〗_O^(••)) is needed, as the former is the vital requirement for sensing chemical reactions, while the latter facilitates the replenishment of adsorbed oxygen ions on the surface. We determined the relation between sensor response (sensitivity) and the amounts of adsorbed oxygen ions (O_(2(ads))^-,O_((ads),)^- O_2(ads)^(2-),O_((ads))^(2-)), water/hydroxide groups (H2O/OH^-), oxygen vacancies (〖V_O^•,V〗_O^(••)), and ordinary lattice oxygen ions (O_lattice^(2-)) as a function of temperature. During hydrogen (H2) testing, the different oxidation states (W6+, W5+, and W4+) of WO3 were quantified and correlated with oxygen vacancy formation (〖V_O^•,V〗_O^(••)). We used a combined application of XPS, UPS, XPEEM-LEEM, and chemical, electrical and sensory analysis for H2 sensing. We established a correlation between the H2 sensing mechanism of WO3, sensor signal magnitude, the amount of adsorbed oxygen ions, and sensor testing temperature.

This paper also provides a review of the detection, quantification, and identification of different adsorbed oxygen species. The different surface and bulk-sensitive characterization techniques relevant to analyzing the SMOs-based sensor are tabulated, providing the sensor designer with the chemical, physical, and electronic information extracted from each technique.

Published: December 2022

This study aims to examine the mediating role of SME performance in the relationship between entrepreneur competence (EC) and satisfaction (ES) in Indonesia. Data were analyzed using Structural Equation Modeling (SEM), AMOS 24. A total of 380 employers in Pekanbaru City, Riau Province, were selected as the participants. The results showed that SME performance partially mediates the relationship between entrepreneur competence and satisfaction. This is because the direct effect between SMEs' performance and ES is still significant. The implication of this study implies that there is a need to improve the SMEs' performance to increase their competence and create satisfaction for employers. Moreover, entrepreneurs who are satisfied with their businesses always wish to stay longer and do not give up on it.  
MAA: Multi-objective Artificial Algae Algorithm for Workflow Scheduling in Heterogeneous Fog-Cloud Environment
Authors: Shukla Prashant , Pandey Sudhakar
Published: December 2022

Cloud Computing (CC) is the most popular tool of choice for conducting scientific experimentation on Cloud Servers (CDs). It can be even more efficient strategy to use Fog Computing (FC) for allocating and executing operations on Fog Devices (FDs). Complex scientific operations need the effective use of virtual machines (VMs). Scientific workflow scheduling problem is regarded as NP-complete. This problem is constrained by various factors, such as Quality of Service (QoS), interdependence between tasks, user deadlines, etc. There is a very less research available on scientific workflow scheduling in Fog-Cloud Environments (FCE). Classical scheduling techniques, evolutionary optimization algorithms, and other methodologies are the available solution to this problem. In this paper, an efficient meta-heuristic approach named Multi-objective Artificial Algae (MAA) algorithm is presented for scheduling scientific workflows in heterogeneous FCE. In the first phase, the algorithm preprocesses scientific workflow and prepares a tasks list. In order to speed up execution, bottleneck tasks are executed with high priority. The MAA algorithm is used to schedule tasks in the following stage to reduce execution times, energy consumption and costs. In order to effectively use fog resources, the algorithm also utilizes the weighted sum based objective function. The suggested approach is evaluated using five benchmark scientific workflows. To verify the performance, the proposed algorithm's results are compared to those of conventional and specialized scheduling algorithms. In comparison to previous methodologies, the results demonstrate significant improvements in execution time, energy consumption and total cost without any trade-offs.

Authors: Mwebaze Thomas , Buyinza Faisal
Published: December 2022

This article examines the relationship between economic growth and exports in Uganda using annual time series data and in the ARDL framework. The study provides evidence on the short and long run relationship between economic growth and exports and tests the export-growth-led hypothesis for Uganda. Our results reveal that exports significantly promote both short-run and long run economic growth in Uganda within the study period. Secondly, the results adjustment coefficient is negative and statistically significant, implying that there is a long-run relationship between exports and economic growth. Also, the adjustment coefficient indicates that the speed of adjustment to equilibrium is about 86% in case of any shock to the economy. In addition, our results show that foreign exchange rate, inflation and trade openness have a significant and negative effect on economic growth while private credit and capital formation have a positive and significant effect on long-run economic growth rate in Uganda. On the other hand, gross capital formation, private sector credit and exchange rate growth have a positive and significant effect on economic growth rate in Uganda in the short run. The findings of this study suggest that there is need for increased government commitment to boost production and quality of exports in order to exploit the untapped export potentials of the country. Secondly, government needs to put in place measures to ensure efficient utilization of external resources and a clear road map for trade openness. Finally, government should also put in place sound investment policies like ease of access to affordable credit plus stable macroeconomic conditions in form of low inflation and a stable exchange rate in order to stimulate economic growth that will further boast the country’s overall growth and development potentials.

This study was conducted to evaluate the bio-herbicidal potential of shoot system of Ononis vaginalis Vahl. on Rumex dentatus L.; a major pest of broad bean (Vicia faba L.). General phytochemical screening of O. vaginalis showed an abundant production of allelochemicals as secondary metabolites which may play a role as natural herbicides. Germination and growth bioassays were conducted to investigate the effect of aqueous and crude powder of the donor species on some germination and growth parameters. Results showed that there was no significant effect of low concentrations on seed germination of V. faba in both pure and mixed cultures on contrarily to those recorded for R. dentatus; gradual decrease with increasing O. vaginalis concentrations in both cultures. On the other hand, total phenolics in V. faba shoot and root showed an increase under different treatments except in high concentration treatment. While in R. dentatus, total phenolics and flavonoids fractions in root of V. faba were decreased in response to different concentration treatments. On the other hand, flavonoids increase in shoots of R. dentatus, while decreasing in roots in mixed culture under high concentration treatments. In conclusion, the study confirmed the integration of O. vaginalis in existing weed control management systems. O. vaginalis could be further tested for suppression of weed growth under field conditions.
The Microscopic Foundations of Solid Compositions in Planetary Systems

Dust grains in the interstellar media and protoplanetary disks have roughly equal abundances in carbon and silicates. When coagulating and growing into larger astronomical objects, theories bridging grains to the growth products struggle to quantitatively explain the <10−2 carbon to silicon ratio in rocky planets. Here we propose a new paradigm that self-consistently establishes the microscopic foundations for dust evolution theories by integrating them with ab initio computational chemistry. CO and H2O, the most substantial astrophysical molecules that can be “glues” in grain growths, exhibit drastically weaker adsorption on carbonaceous grains than silicates. This effect inhibits the inclusion of carbon in planetesimals by the desorption of these “glue molecules” from warm carbonaceous grains close to the host star (≲ 8 AU for a solar-system-equivalent), giving rise to the high Si-C abundance ratios in warm regions. The same mechanism semi-quantitatively yields the trend of increasing carbon abundances in the outer parts of our Solar system and likely generic planetary systems.

Published: December 2022

Background. The gaps at the margins of restorative composite resin can increase as the carious process occurs underneath the materials, causing further demineralization along the tooth cavity wall. The aim of this study was to evaluate the effects of restorative resin composite containing hydrated calcium silicate (hCS) filler on enamel protection against demineralization by simulating microleakage between the test material and teeth in a cariogenic environment.
Methods. The experimental resin composites were composed of 70 wt% filler, which was mixed with a glass filler and hCS in a weight ratio of 70.0% glass (hCS 0), 17.5% hCS + 52.5% glass (hCS 17.5), 35.0% hCS + 35.0% glass (hCS 35.0), and 52.5% hCS + 17.5% glass (hCS 52.5). A light-cured experimental resin composite disk was positioned over a polished bovine enamel disk, separated by a 30-µm gap, and immersed in artificial saliva with pH 4.0 for 15, 30, and 60 days. After the immersion period, the enamel disk was separated from the resin composite disk and evaluated using a microhardness tester, atomic force microscopy, and polarized light microscopy. The opposing sides of the enamel and resin composite disks were observed using scanning electron microscopy/energy dispersive X-ray spectrometry (SEM/EDS).
Results. The enamel surface showed a significant increase in microhardness, decrease in roughness, and remineralization layer as the proportion of hCS increased (P < 0.05). In the SEM image, enamel surface with hCS 35.0 and 52.5 after all experimental immersion periods showed a pattern similar to that of a sound tooth.
Conclusions. The results demonstrated that increasing the hCS filler level significantly increased the prevention effect of enamel demineralization compared to restorative resin composites containing conventional dental glass filler. Despite some microleakage exposed to a cariogenic environment, these novel composites may be promising dental biomaterials for protecting teeth against demineralization and preventing secondary caries around the restorations.

Published: December 2022

Objective: To assess the effect of Pulse indicator continuous cardiac output (PiCCO) compared to traditional hemodynamic monitoring in patients with acute respiratory distress syndrome (ARDS).
Methods: We conducted a meta-analysis of randomized controlled trials (RCTs) published from Jan. 1, 2012 to Oct. 1, 2022 comparing PiCCO to traditional hemodynamic monitoring in patients with ARDS.
Results: We identified 9 RCTs and combined data from 747 patients, including 369 patients in the experimental group and 378 patients in the control group. Compared to the control group, patients in experimental group have shorter mechanical ventilation time (MD: -3.91, 95% CI [-4.91, -2.92], P＜0.00001, random eﬀects model) and length of ICU stay (MD: -5.23, 95% CI [-6.64, -3.82], P＜0.00001, random eﬀects model). 28-day mortality were observed lower in patients monitored by PiCCO compared to that in control group (RR: 0.53, 95% CI [0.39, 0.73], P=0.0001, fixed eﬀects model).
Conclusions: PiCCO monitoring can effectively reduce the 28-day mortality of ARDS patients, shorten the duration of mechanical ventilation and ICU stay, and has a positive significance for improving the prognosis of ARDS patients.

Published: December 2022

Pathophysiological mechanisms of liver dysfunction in Turner syndrome (TS) are not well understood. We examined systemic inflammatory indices (neutrophil-lymphocyte-ratio, NLR; AST-to-platelet ratio, APRI; AST-to-lymphocyte ratio, ALRI; and GGT to platelet ratio, GPR) in patients with TS and their potential application in describing the endocrine and metabolic abnormalities of these subjects.
We performed a retrospective analysis of medical records of 79 TS patients (mean age 32.5 years ± 9.2 SD) followed in the University Hospital of Nancy. Using matched-pair analyses based on age and BMI, we compared 66 TS patients (25.6 ± 7.3 years; BMI 25.9 ± 6.3 kg/m2) to 66 healthy controls (24.7 ± 6.8 years; BMI 26.0 ± 6.7 kg/m2).
Liver abnormalities were present in 54% of the TS subjects. In this subgroup of patients with hepatic abnormalities, inflammatory indices (NLR, APRI, ALRI, GPR) were significantly higher than that observed in TS patients with normal liver function. In the matched-pair analyses, indices APRI, ALRI, and GPR were higher in TS patients than in healthy controls. The results of the logistic regression revealed significant associations between a diagnosis of TS and APRI, ALRI, GPR, liver dysfunction, low bone mineral density, and hypothyroidism.
In conclusion, systemic inflammatory indices NLR, APRI, ALRI and GPR are significantly associated with liver dysfunction in TS. These observations increase our understanding regarding the pathophysiological mechanisms of liver dysfunction in TS. Larger prospective studies are needed to confirm our findings and to explore a prognostic value of inflammatory indices and their potential utility for clinical practice.

Background: Ischemic stroke (IS) is a heterogeneous condition with varied mechanisms. Some patients have more than one stroke mechanism underlying the incident stroke. This study aimed to examine the association of dual stroke mechanisms among ischemic stroke patients with risk factors and clinical outcomes.
Methods: Case records of adult patients with IS diagnosed using TOAST criteria in a University Stroke-Registry were reviewed for presence of dual IS mechanisms- viz. combinations involving small vessel disease(SVD), cardio-embolism(CE), or large artery atherosclerosis(LA). Outcomes were classified as good (modified Rankin Score=0-3) or poor (4-6). Univariate and multivariate methods of analysis were used.
Results: Among 1220 patients with IS (age: 64+13 years; M:F::63%:37%), 177(14.5%) had an additional mechanism of stroke. SVD(51%) was the most common second mechanism, while CE(23%) and LA stroke(25%) were similar in frequency. On univariate analysis, patients with dual stroke mechanisms were significantly older(p<0.001), had higher frequency of conventional risk factors (p<0.007), abnormal brain MRI(p=0.004) and worse outcomes(p=0.058). On logistic regression analysis, poor outcomes at hospital discharge or 12 month follow-up were independently associated with: older age(p=0.007); female gender(p=0.017); poor sensorium(p<0.001); and type of primary stroke(p<0.001).
Conclusions: Up to one in seven patients with ischemic stroke may have an additional mechanism of stroke. Such patients are likely older, with poorly controlled risk factors, worse sensorium and possible worse outcomes. Small vessel disease is the most common additional stroke mechanism. Studies to explore the influence of dual stroke mechanisms on outcomes as well strategies for secondary prevention are indicated.
Synthesis of hierarchical micro-mesoporous ZSM-5 zeolite and its catalytic activity in benzylation of mesitylene
Authors: Krishnamurthy Manikandan , Swaminathan M.
Published: December 2022

Hierarchical micro-mesoporous ZSM-5 (MFI type) zeolite was synthesized by using corn plant stem pith powder from agricultural waste as hard template under simple hydrothermal method. The additional porosity generated using this pith powder into the zeolites precursor gel yielded hierarchical micro-mesoporous ZSM-5 zeolite (C-ZSM-5). Conventional microporous ZSM-5 (ConvZSM-5) was prepared. The prepared C-ZSM-5 zeolite exhibited 89% conversion, much greater than ConvZSM-5 (33%). Selectivity in the formation of 2-Benzyl-1, 3,5-trimethylbenzene, by benzylation with C-ZSM-5 (70%) is more than two times than ConvZSM-5 (33%). This benzylation can be used as a test reaction to evidence the hierarchical micro-mesoporous nature of the material. The product was further confirmed by 1HNMR and 13CNMR.The hierarchical pores present in the catalyst further improved the stability of the zeolites.
