Targeting the Endocannabinoid System
Authors: Editorial Staff  
Published: October 2022

Metabolism, inflammation, neural development, neuronal excitation, and cell division are some of the many biochemical functions in which endocannabinoid system is significantly involved. 9-tetrahydrocannabinol (THC) and cannabidiol (CBD), which are important phytocompounds found in Cannabis sativa, have demonstrated the ability to target the endocannabinoid system. The potential therapeutic applications of both phyto- and synthetic cannabinoids as well as their mechanisms have been explained in a study by Keimpema and colleagues. In spite of the fact that there are promising results for endocannabinoid modulation in certain kinds of epilepsy, there is significantly more that has to be perceived about the potential role of phytocannabinoids and their targets before they can be considered efficacious and safe therapeutics.

Published: October 2022

Statins induce hepatotoxicity via reduced levels of Coenzyme Q10, inflammation, and oxidative stress. Coenzyme Q10 is anti-apoptotic and possesses an antioxidative potential and hence has been studied for its hepatoprotective potential. However, owing to the differing mechanisms of prevention of damage and its reversal, we hypothesize that coenzyme Q10 will have varying efficacy as a protective versus a therapeutic approach. An experimental study of 3 weeks was conducted in the department of Pharmacology on a sample of 35 mice, randomly divided into 7 groups. Group 1 was used as a control. Group 2 received simvastatin 50mg/kg/day of simvastatin intraperitoneally (I/P). Group 3 received I/P 50mg/kg/day rosuvastatin. Group 4 received 50mg/kg/day of simvastatin+10mg/kg of coenzyme Q10. Group 5 received 50mg/kg/day of rosuvastatin+10mg/kg of coenzyme Q10 I/P. In group 6 simvastatin 50mg/kg & 7 rosuvastatin 50mg/kg was given for a week, and 10mg/kg of Coenzyme Q10 was started in the 2nd week and continued for 2 weeks. Hepatic damage was observed in groups 2,3,6 and 7 indicated by raised ALT levels of 320.4, 179.8, 301.4, and 186.8 and raised AST levels of 320, 196, 421.4, and 307.6. Bilirubin stayed within normal limits. Coenzyme Q10 prevents statin-induced liver damage but has no role as a therapeutic agent once the liver damage has already occurred.
Annealing temperature effect on structural properties of tin oxide nanoparticles
Authors: G. Arora  , I. Hiroya  
Published: October 2022

Tin oxide (SnO2) nanoparticles were synthesized employing simple sol–gel method. Modification in the structural, morphological and optical properties of the as-synthesized tin oxide nanoparticles due to various solution pH (6–12) and thermal annealing at 400 °C (Experiment 1) was studied. X-ray diffraction results of the tin oxide nanoparticles prepared from the precursor solution pH 8 and annealed at 400 °C showed the formation of tin oxide tetragonal phase (SnO2-t) and the surface morphology of the SnO2-t nano- particles studied by scanning electron microscope revealed the formation of spherical shaped agglomerations. Hence, the tin oxide nanoparticles prepared from the solution pH 8 were annealed at 200, 400, 600 and 800 °C in order to study the effect of annealing at various temperatures on the structural, morphological, optical and vibrational properties of tin oxide nanoparticles (Experiment 2). When the annealing temperature was increased to 600 and 800 °C, mixed phases of SnO2-t and tin oxide orthorhombic system (SnO-o) were formed. Various solution pH and annealing temperatures influenced the direct band gap value. SnO2-t phase synthesized from the solution pH 8 and annealed at 400 °C showed a direct band gap of ~4.50 eV. The tin oxide samples annealed at various temperatures showed a slight shift in the fluorescence peak observed at ~327 nm. Raman studies of the samples obtained from Experiment 1 and Experiment 2 showed a slight shift in the vibrational frequency. I–V studies carried out to investigate the electrical properties of the SnO2 thin film formed by simple drop casting method revealed better ohmic contact and its suitability for gas sens- ing applications.
National Assembly: An Empty Promise to Democracy
Authors: Noobanjong Koompong 
Published: October 2022

Throughout history, architecture and urban design have been manipulated to serve politics. Capitals and capitols have become grand symbolic tools for the state, which should be understood in terms of their political and cultural contexts that helped bring them into being.
Accordingly, by presenting a multi-dimension critical inquiry of the National Assembly in Bangkok, Thailand, this paper argues via semiology, or a study of signs that the design of the Assembly fails to signify its original purpose: democratic ideology and practice. Ironically, however, such symbolic deficiency precisely captures the reality of democracy in Thailand. Here, democracy does not function merely as an ideology, but as a political discourse full of incongruity, paradox, manipulation, and deception.
In addition, through a critical urban study, this article reveals that the obscurity of the Assembly both in Thai architectural literature and in the urban fabric of Bangkok exemplifies the true state of the legislative branch of the government. A lack of integration between the Assembly and the physical condition of Bangkok notably the Rajadamnoen Avenue, ‘ the corridor of power,’ further demonstrates that the parliament is a rather weak and neglected institution. Significant political policies and decisions are formed and madeelsewhere. The parliamentary system acts merely as a tool for self-legitimization and authority-preservation in a game of power politics in Thailand.
INVESTIGATING THE ACUTE CARDIAC EFFECTS ON AQUATIC ORGANISMS BY GASOLINE POLLUTION IN LAKE-SIMULATED BEAKERS USING Daphnia magna
Authors: JEONG ESTHER 
Published: October 2022

Petroleum and its product are one of the most common water and soil pollutant sources and have caused marine and terrestrial spillages. The oil from these spills from polluted groundwater returns to the human population through numerous pathways by consuming fish and shellfish. Daphnia magna, also known as the water flea, is a small planktonic crustacean that lives in bodies of freshwater. They are an ideal model for testing the toxicity of substances due to their high sensitivity to environmental chemicals. Therefore, the data acquired with Daphnia can serve dual purposes: one for an indicator of environmental pollution and the other for estimating adverse effects on the human body, though not directly.
In this study, a lake-simulated model was created using organic materials, laboratory shakers, and temperature control systems in groups of beakers, and their variable dependency was investigated. It was concluded that Daphnia's heartbeat was significantly depressed by the existence of gasoline pollution. Moreover, the impact on the cardiac function was linearly correlated with the lake-simulated model's gasoline volume, organic material concentration, and temperature. However, there seemed to be complicated conditions that existed mutually depending on the variables. Further study may be necessary for any underlying mechanism within the organs in the body.

Herbal medicines are used mainly in developing countries for primary health care because of their closeness with human body and have minimum side effects.Leaf and stem extracts of Cassia alata and Cleome gynandra were investigated for antimicrobial activity against clinically important pathogens such as Acinetobacterbaumannii(MCC 2076), Pseudomonas otitidis (MCC 2509), Pseudomonas oleovorans(MCC 2566), Enterococcus faecalis(MCC 2041) and Bacillus cereusby disc diffusion method.Acetone and water extracts of C. gynandra leaf showed maximum inhibition against Gram positive E. faecalis and Gram negative P. oleovorans (20mm). Acetone extract of C. gynandra stem showed maximum inhibition against Gram positive E. faecalis (19mm). Acetone extract of C. alata leaf showed maximum inhibition against Gram positive B. cereus(19mm) and ethanol extract of C. alata stem showed maximum inhibition against Gram positive B. cereus(14mm).GC/MS analysis was carried out for Cleome gynandra leaf sample which showed maximum inhibitory activity against the pathogen P. oleovorans(20mm).Important phytochemicals present in the leaf sample were 2-hydroxy-2-methyl-4-pentanone, Methane, sulfinylbis, 1,2-Benzenedicarboxylic acid, Tetradecanoic acid, Hexadecanoic acid, 2-Hexadecen-1-ol, 3,7,11,15-tetramethyl and 9,12,15-Octadecatrienoic acid. The phytochemicals contribute the antibacterial properties, which is responsible for the therapeutic effect.The plants have shown susbtantial activity against tested bacteria. The antibacterial activity observed in the study could be due to the presence of phytochemicals. The plants could serves as promising ‘‘leads’’ in the development of effective antimicrobial drugs.

Published: October 2022

Aim: Active mining in Kilembe copper mine, Kasese district, Uganda ended about four decades ago. However, various health problems are believed to be from the effect of mining activities that took place in the area. In this study therefore, we quantified the concentration of trace metals: chromium (Cr), cadmium (Cd), zinc (Zn), iron (Fe), lead (Pb), arsenic (As) and copper (Cu) in cabbages and tomatoes grown in Kilembe mining area and assessed the health risks from consumption of the vegetables after 40 days and 120 days of growth.
Study Design: This study employed quantitative research design.
Place and Duration of Study: The experiments were done at Department of Chemistry, Mbarara University of Science and Technology, Uganda from 2018 to 2019.
Methodology: The vegetables were planted, and their roots, leaves, fruits and stems were sampled after 40 days and 120 days. Elemental analysis was performed using atomic absorption spectrophotometry. The estimated daily intake (EDI), target harzard quotient (THQ) and cancer risks were calculated to explore health risks that could arise from consumption of the vegetables.
Results: The levels of Fe, Cu, Zn and Cr did not exceed WHO/FAO permissible limits. The EDI of Fe (294.678 × 10-4 mg/kg/day) was the highest while the lowest was 0.052 × 10-4 mg/kg/day for Cr. The THQ ranged from 0.000004 to 1.3134. Cancer risk values ranged from 0.126 × 10-4 to 28650 × 10-4.
Conclusion: There are discernable non-carcinogenic health risks (THQ >1) and cancer risks associated with consumption of cabbages and tomatoes by the local inhabitants. The risks are escalated in children who consume both vegetables after 40 days of growth. Arsenic and Cd poses the highest carcinogenic health risk while Pb poses the highest non-carcinogenic health risk. Consumption of the vegetables after 120 days of growth poses lower health risks.

Heat stress from global warming and climate change, which result in an ongoing rise in Earth's temperature, has a detrimental effect on the growth and health of dairy animals. The animal experiences heat stress when it cannot release enough heat to maintain homeothermy. The degree of heat stress dairy animals experience depends on the ambient temperature and humidity. In dairy animals, heat stress reduces feed intake, milk production, reproductive efficiency, and immune function. This article concentrated on the micronutrients that lessen the damaging effects of heat stress on dairy animals. Micronutrients are vital substances that life requires in minute amounts. Major minerals, trace minerals, and vitamins are all included. Micronutrients support the maintenance of animal production, enhance nutrient utilization, effectively combat oxidative stress, and strengthen the weak immune system. Minerals are crucial for maintaining an animal's normal physiological processes. However, it is a belief that animals' reactions to heat stress increase mineral loss through excretion. Therefore, adding minerals to the diet (such as Dietary Cation-Anion Difference, Zinc, Chromium, Selenium, etc.) may help to reduce the harmful effects of heat stress. Vitamins serve as cofactors for enzymes, act as catalysts in a number of metabolic pathways, and are crucial for an animal's normal growth and development. The addition of vitamins (such as Vitamin E, Niacin, etc.) to dairy animals' diets may also help to mitigate the harmful effects of heat stress.

Background: Uncorrected refractive errors (RE) are a major cause of visual impairment. They affect a large proportion of the population globally and have psychological and socio-economic effects on the individual, family and society. They could lead to poor quality of life.
Aim: To determine the pattern and predisposing factors of refractive errors among patients seen in the outpatient clinic.
Methodology: A cross-sectional, descriptive study involving patients with refractive error that presented to the eye clinic in the year 2017. Data were obtained from patients’ records, entered into and analysed using IBM SPSS version 25.
Results: A total of 300 patients with refractive errors were seen in the period of study. This comprised of 93 males and 207 females with mean age of 40.13±17.6 years. The commonest presenting complaint was blurring of both far & near vision (24%), other presenting complaints in decreasing order of frequency were blurring of distant vision, itching, blurring of near vision, eye pain, headache and red eyes in 18%,15%, 9.6%, 5.6%, and 3.2% respectively. Presbyopia was noted in 55.3% while myopia, anisometropia, astigmatism and hypermetropia were noted in 20.7%, 19.3%, 7.0% and 1.3% respectively. Nuclear sclerosis was the commonest co-existing ocular pathology or morbidity.
Statistically significant association was found between age of the patients and presence of ocular disease existing with RE (p=0.016).
Conclusion: Fifty-one percent of the study population had refractive errors. The commonest refractive error was myopia while hypermetropia was the least common refractive error in this environment.
Water‐Induced Self‐Blown Non‐Isocyanate Polyurethane Foams
Authors: Bourguignon Maxime , Grignard Bruno , Detrembleur Christophe 
Published: October 2022

AbstractFor 80 years, polyisocyanates and polyols were central building blocks for the industrial fabrication of polyurethane (PU) foams. By their partial hydrolysis, isocyanates release CO2 that expands the PU network. Substituting this toxic isocyanate‐based chemistry by a more sustainable variant—that in situ forms CO2 by hydrolysis of a comonomer—is urgently needed for producing greener cellular materials. Herein, we report a facile, up‐scalable process, potentially compatible to existing infrastructures, to rapidly prepare water‐induced self‐blown non‐isocyanate polyurethane (NIPU) foams. We show that formulations composed of poly(cyclic carbonate)s and polyamines furnish rigid or flexible NIPU foams by partial hydrolysis of cyclic carbonates in the presence of a catalyst. By utilizing readily available low cost starting materials, this simple but robust process gives access to greener PU foams, expectedly responding to the sustainability demands of many sectors.
Durable Nickel‐Iron (Oxy)hydroxide Oxygen Evolution Electrocatalysts through Surface Functionalization with Tetraphenylporphyrin

Published: October 2022

AbstractNiFe‐based oxides are one of the best‐known active oxygen evolution electrocatalysts. Unfortunately, they rapidly lost performance in Fe‐purified KOH during the reaction. Herein, tetraphenylporphyrin (TPP) was loaded on a catalyst/electrolyte interface to alleviate the destabilization of NiFe (oxy)hydroxide. We propose that the degradation occurs primarily due to the release of thermodynamically unstable Fe. TPP acts as a protective layer and suppresses the dissolution of hydrated metal at the catalyst/electrolyte interface. In the electric double layer, the nonpolar TPP layer on the NiFe surface also invigorates the redeposition of the active site, Fe, which leads to prolonging the lifetime of NiFe. The TPP‐coated NiFe was demonstrated in anion exchange membrane water electrolysis, where hydrogen was generated at a rate of 126 L h−1for 115 h at a 1.41 mV h−1degradation rate. Consequently, TPP is a promising protective layer that could stabilize oxygen evolution electrocatalysts.

Published: October 2022

AbstractDesigning metal‐organic framework (MOF)‐based catalysts with superior oxygen evolution reaction (OER) activity and robust durability simultaneously is highly required yet very challenging due to the limited intrinsic activity and their elusive evolution under harsh OER conditions. Herein, a steady self‐reconstructed MOF heterojunction is constructed via redox electrochemistry and topology‐guided strategy. Thanks to the inhibiting effect from hydrogen bonds of Ni‐BDC‐1 (BDC=1,4‐benzenedicarboxylic acid), the obatained MOF heterojunction shows greatly improved OER activity with low overpotential of 225 mV at 10 mA cm−2, relative to the totally reconstructed Ni‐BDC‐3 (332 mV). Density function theory calculations reveal that the formed built‐in electric field in the MOF heterojunction remarkably optimizes the ad/desorption free energy of active Ni sites. Moreover, such MOF heterojunction shows superior durability attributed to the shielding effect of the surface‐evolved NiOOH coating.

Published: October 2022

AbstractSerious safety risks caused by the high reactivity of lithium metal against electrolytes severely hamper the practicability of lithium metal batteries. By introducing unique polymerization site and more fluoride substitution, we built an in situ formed polymer‐rich solid electrolyte interphase upon lithium anode to improve battery safety. The fluorine‐rich and hydrogen‐free polymer exhibits high thermal stability, which effectively reduces the continuous exothermic reaction between electrolyte and anode/cathode. As a result, the critical temperature for thermal safety of 1.0 Ah lithium‐LiNi0.5Co0.2Mn0.3O2 pouch cell can be increased from 143.2 °C to 174.2 °C. The more dangerous “ignition” point of lithium metal batteries, the starting temperature of battery thermal runaway, has been dramatically raised from 240.0 °C to 338.0 °C. This work affords novel strategies upon electrolyte design, aiming to pave the way for high‐energy‐density and thermally safe lithium metal batteries.
Advances in Biosignal Sensing and Signal Processing Methods with Wearable Devices
Authors: Matthews Jared , Kim Jihoon , Yeo Woon‐Hong 
Published: October 2022

AbstractWearable devices have received significant attention recently for their ability to monitor critical physiological signals noninvasively, such as electrocardiography, electroencephalography, electromyography, and photoplethysmography. These bio‐integrated wearable systems can potentially fill gaps in conventional clinical practice by providing highly cost‐effective health characterization and portable continuous health monitoring. Further, the physiological signals measured by wearables require post‐processing to derive meaningful values, such as heart rate or blood oxygen saturation. This requirement, in conjunction with the smaller form factor and limited sensor count of the miniaturized systems, often necessitates robust signal processing and data analysis to approach the stringent performance specifications of conventional medical devices, and machine learning techniques have found success in filling this analytical role for their ability to learn complex functional relationships. Thus, this review outlines a systematic summary of the latest research on various wearable devices and their biosignal sensing and signal processing methods, emphasizing machine learning. We also discuss the developmental challenges and advantages of current machine‐learning methods, while suggesting research directions for future studies.
