Fabrication of PDMS lenses with precisely controlled curvatures by confined sessile drop technique
Authors:   , Kaewmanee Natthanan
Published: November 2023

This research presented a novel approach for forming lens form elastomeric polydimethylsiloxane (ePDMS) with precisely controlled properties such as curvature, focal length, and magnification via the confined sessile drop technique. This technique is simple, rapid, and cost effective for mass-scale production. The ePDMS lens with plano-convex shape can be directly attached onto a smartphone camera and transform into portable smartphone digital microscope. The fabrication procedure of ePDMS plano-convex lens involved an injection of liquid PDMS (lPDMS) 3-100 µL onto a circular disk with the diameter in the range 2-10 mm. The resistances to spreading by sharp enabled the reproducibility of spherical cap of lPDMS. The lPDMS axisymmetrically spread under the balance between the gravitational force and interfacial tension force for precisely controlled spherical cap. A thermal treatment at 80 oC for 30 min cured the spherical caps lPDMS into a bubble-free solid ePDMS plano-convex lens. The ePDMS plano-convex lens with focal lengths of 3.4-55.2 mm and magnifications of 4.5X-73.5X could be repeatedly reproduced. Portable smartphone digital microscope can be used to capture small objects that cannot be seen with the naked eye such as micro-printing, and gun shoot residue. High-resolution panorama microscope images without distortion were also demonstrated.
SYNERGISTIC EFFECTS OF CEPHARANTHINE AND CELECOXIB IN HUMAN COLORECTAL CANCER CELLS
Authors:   , Lerdwanangkun Parawee
Published: November 2023

Celecoxib, a specific cyclooxygenase 2 (COX-2) inhibitor, is clinically suggested as adjunctive therapy for preventing the progression of colon polyps to colorectal cancer. However, this drug is used at high dose in a long period of time for this indication. This leads to the cardiovascular toxicity concern. Combination of celecoxib with other anticancer agents is a strategy for improving the efficacy of celecoxib. This study aimed to investigate anticancer effect of celecoxib – cepharanthine combination on human colorectal cancer HT-29 cells. Effects of the drugs on cell viability were determined by resazurin assay. Celecoxib and cepharanthine decreased viability of HT-29 cells with IC50 > 50 µM and at 5.22 ± 0.28 µM, respectively after 48 h of exposure. Celecoxib at 5, 10, 20, and 40 µM were combined with cepharanthine at 1.25, 2.5 and 5 µM for HT-29 viability test. All combinations had synergistic effects on the cell viability with combination indices less than one (CI < 1). The combinations of celecoxib at 20 and 40 µM and cepharanthine at 1.25 and 2.5 µM were investigated further. When compared to each drug, these combinations did not have additive/ synergistic effects on COX-2 and NADPH oxidases (NOX1 and NOX2) expression determined by real time RT- PCR, PGE2 production determined by ELISA, and ROS generation determined by DCFH-DA assay. The combinations significantly increased HT-29 cell accumulation at the G1 phase of the cell cycle when compared to the effects of each drug. The cell cycle was determined by propidium iodide (PI) staining with fluorescence flow cytometer. The effects on cell cycle arrest of these combinations may come from the increase in cyclin-dependent kinase (CDK) inhibitor p21 and the decreased in cyclin A expression. The combination of 40 µM celecoxib – 2.5 µM cepharanthine significantly increased p21 but decreased cyclin A expression when compared to each drug. The combinations significantly increased HT-29 apoptosis determined by annexin V/FITC and PI staining with flow cytometer when compared to each drug. Similarly, their apoptotic induction effects correlated with the increase in pro-apoptotic BAX and the decrease in anti-apoptotic Bcl-XL expression induced by these combinations. The results from this study reveal the synergistic anticancer effect of celecoxib – cepharanthine combinations at sub-IC50 concentrations. This finding may be useful for reducing the dose and toxicities of celecoxib in colorectal cancer prevention. Further investigations are needed to confirm these results.

Authors:   , Khumsapsiri Numpung
Published: November 2023

The aim of this study was to investigate the effect of multidirectional reach training on dynamic balance in individuals with stroke. Sixteen participants with stroke were recruited and randomly assigned into two groups, experimental and control. Participants in the experimental group were trained with the multidirectional reach training for 30 minutes and conventional physical therapy 30 minutes/day, 3 days/week for 4 weeks. Participants in the control group were received a conventional physical therapy for 30 minutes/day, 3 days /week for 4 weeks. The outcomes were limits of stability, weight bearing squat, multi-directional reach test, Fullerton advance balance scale, and Fugl Meyer Assessment. All of the outcome measures were measured at pre-training (Wk0), post-training (Wk4), and follow-up (Wk8). A two-way repeat measurement ANOVA was conducted to address the research questions. At post- training, and follow-up, the results showed that participants in the experimental group reported improvement of dynamic balance than the control group. Furthermore, Fullerton advance balance scale which refers to activity was more improve at follow-up in the experimental group than control group. The result of this study provides evidence that multidirectional reach training is effective for improve dynamic balance in individuals with stroke.
Stability of complex host-guest structure and superconductivity in the alkali and alkaline earth metals under high pressure
Authors:   , Tsuppayakorn-aek Prutthipong
Published: November 2023

This thesis investigates the existence of host-guest structure under high pressure in elemental metals such as Mg, Li, Ca, Sc and As. The new stable structure of magnesium (Mg) is predicted by ab initio random structure searching (AIRSS) technique under high pressure. The I4/mmm and Pnma structures have been predicted to give the normal metallic state at the pressure above 160 GPa. Moreover, for Li, the AIRSS technique is used to identify the host-guest (HG) of lithium (Li). The distribution of electrons between the host-host atoms has also been investigated by electron localization function. The strongly localized electron of π bond has led to the stability of the HG structure under high pressure.  The calculation result from Ca in the metallic phase has led to the discovery of high-Tc superconductivity, with a Tc of 25.2 K at 160 GPa. The Tc of this monoclinic Cc structure is in good agreement with experiment. In addition, the explanation of Sc-II revealed that the 3cH and the 4cG structures coexist which form the HG structure with CH/CG ratio of 4/3 at 70 GPa. The  AIRSS technique predicts the high pressure structure of Sc-III to be P41212 and also reveals Tc of 8.36 K which is in good agreement with the experimental result. Furthermore, the body-centered tetragonal (bct) structure in arsenic (As) has been predicted using AIRSS technique at 150 GPa. The calculation suggests transition sequence from the simple cubic structure transforms to the host-guest structure at 41 GPa and then to the bct structure at 81 GPa. The spectral function of bct structure is higher than those of the bcc structure. This result is also reported to be Tc  4.2 K at 150 GPa.
Theoretical studies of electronic properties of Methylammonium lead iodide perovskite under high pressure
Authors:   , Sakulsupich Vichawan
Published: November 2023

Many researchers have claimed that hybrid organic−inorganic perovskite (HOIP) could hold the key to the new era of photovoltaic technology, owing to its efficiency, both energetically and economically. Despite all its merits, perovskite solar cell is plagued by an indispensable draw back; it degrades precipitously under sunlight. Not only sunlight that has destructive effects on perovskites, humidity and high temperature also cause the compound to disintegrate. In this work, we present a review on structural properties of the archetypal perovskite, the methylammonium lead iodide perovskite, as reported by various experiments. We performed density functional theory calculations to study the role of methylammonium dynamics to the structural properties. We also cover the most up-to-date reports on pressurization experiments. The effects of pressure on the material structural and electronic properties is also discussed.

Authors:   , Winyuchakrit Irada
Published: November 2023

Background: Premenstrual syndrome (PMS) is a recurrent disorder that occurs in the luteal phase of the menstrual cycle. The common sleep problems associated with PMS are insomnia, frequent night time awakenings, and non-restoration of sleep. Nurse is a profession of which are important for providing health care services. They are inclined to more circadian rhythms disturbance because of their working characteristic. Therefore, this study aims to explore whether Premenstrual syndrome associated with sleep quality among a private hospital nurses in Bangkok, Thailand. Method: A cross-sectional study that focused on 307 female nurse who had regular menstruation in one private hospital. The self-reported standard questionnaire was distributed to participants. Sleep quality and PMS was accessed by Pittsburgh Sleep Quality Index (PSQI) – Thai version and Premenstrual Symptoms Screening Tool (PSST) – Thai version respectively. The descriptive data were presented by mean (±standard deviation; SD), number, and percent. The associations of factors and sleep quality were analyzed by Chi-square test. Binary logistic regression was used to identify the adjusted odd ratio of PMS on poor sleep quality. Results: The mean of registered nurse age were 31.38 years (±5.35). Most of them were single (78.9%) and had normal stress level (82.9%). More than half of nurse had been working on rotating shift included nightshift (66.5%). Prevalence of poor sleep quality (PSQI>5) was more than half of them (66.5%). Less of nurses had Premenstrual Syndrome (7.7%). Physical symptoms (48.30%) and overeating/ food craving symptom (41.60%) were the highest reported symptoms of premenstrual syndrome. There was no significant associated between PMS and poor sleep quality. However, physical symptom of premenstrual syndrome was significantly increased odds of poor sleep quality (ORadjusted = 2.15; 95%CI: 1.07 – 4.31). Binary logistic regression showed almost symptoms of premenstrual syndrome were risk to poor sleep quality (OR adjusted >1) however statistical significance was not achieved. Conclusion: More than half of private hospital nurses had poor sleep quality and less of them had premenstrual syndrome. Premenstrual syndrome was not significant associated with poor sleep quality. Almost symptoms of premenstrual syndrome were predicted to risk of poor sleep quality. The results suggested that a management of nurses’ working schedule should consider on their physical activities during their luteal phase of the menstrual cycle.

The soil quality is characterized by adequate nutrients as a result of abundant nutrients cycling bacteria. Most soil in Nigeria has been subjected to different kinds of pollutants resulting from anthropogenic activities which have become a major threatening factor to the quality of soil. This study was carried out to evaluate bacterial density in soil samples collected from hospital wastes dumping site at Chukwuemeka Odumegwu Ojukwu Medical Centre, Uli, Anambra State. A total of 30 composite soil samples were aseptically collected from the site using a sterile soil auger. The samples were analyzed for total heterotrophic bacterial count (THBC) and phosphate solubilizing bacterial count (PSBC) using standard plate technique. The predominant bacterial isolates that aided nutrients cycling were appropriately characterized, and their densities in both impacted and non-impacted soil samples were enumerated. Also, the bacterial isolates were characterized based on morphology, microscopy, and biochemical characteristics. There was an increase in the THBC and PSBC in the impacted soil, and Gram negative rods such as Pseudomonas, Klebsiella, and Micrococcus species (Gram positive) were the bacterial isolates. The study has revealed that wastes generated from hospital enhances microbial proliferation in the soil, which invariably increases soil fertility.

Derivation of Optimum Outfit Density for Surface Warships based on the Analysis of Variations in Work Content and Workforce Density and Productivity with Ship Size
Authors: Spicknall Mark H.
Published: November 2023

The potential impact of a ship’s outfit density on the labor hours required for production, sustainment, and upgrade has been discussed within the domain of warship design for decades. For fixed ship mission, systems capabilities, crew size, specification complexity and maturity, other producibility characteristics, and work schedule, as a ship’s size varies, required production labor hours are impacted in two ways—first by a change in work content and second by a change in worker productivity with available space. Because these impacts are inversely related, there exists an optimum ship size and outfit density that minimizes required labor hours. This paper describes an analysis of optimum outfit density to minimize production labor hours for complex modern surface combatants. The key relationship between available space and worker productivity is defined based on data from multiple industries. This relationship is then used along with knowledge of surface combatant design and shipbuilding processes and production labor requirements to identify an optimum range of overall outfit density to target during ship design. This derived optimum range is validated with other related research and reference to the outfit densities of existing modern surface combatants and what is known about their ease of build. Also discussed are 1) alternative ship design and production paradigms that might allow for ships with higher outfit densities while maintaining efficient production, maintenance, and upgrade and 2) implications of the relationship between available worker space and worker productivity for shipyard planning and work execution.

Law is a rule of rules made to regulate every behavior of the community so as not to carry out deviant activities. One of the actions that deviate from the norms of human life association is social problems, namely problems that occur in society where the perpetrators and victims are the people themselves. One of the deviant actions from the community is the crime of beheading where this beheading began to be rife in the Medan city area. The problem that has recently paraded the streets is often termed Begal. This begal is one of the street crimes, which has recently received serious attention from the public and law enforcement officials. This research was conducted using descriptive qualitative research and using direct interview techniques to police investigators for beheading crimes. The results showed that from several incidents that were successfully revealed by the police, data could be obtained that the perpetrators of this begal crime came from families with low economic and there was no relationship between low punishment for beheading perpetrators to the increase in beheading cases because the legal sanctions given are aimed at providing accountability for the acts resulting from crimes committed by someone
Delayed Onset Muscle Soreness (DOMS): Management Update
Authors: Kancherla Akhil Sai
Published: November 2023

Delayed Onset Muscle Soreness (DOMS) is a prevalent issue in sports medicine and among physically active individuals, causing significant pain and disability. While the exact pathophysiology of DOMS remains incompletely understood, this article delves into non-pharmacological approaches to effectively manage and alleviate its symptoms.

The research discusses multifaceted aspects of DOMS, encompassing its complex etiology, theories, and contributing factors. Numerous theories have been proposed, including delayed inflammatory responses, lactic acid accumulation, muscle spasms, connective tissue damage, and muscle micro-tears. These theories underscore the intricate nature of DOMS and the need for a diverse management approach.

The article explores non-pharmacological strategies to address DOMS, focusing on evidence-based methods. These methods include massage, exercise, nutrition, and natural supplements. Research has shown that massage therapy enhances muscle recovery, exercise therapy reduces soreness, and nutrition therapy through protein and amino acid intake can alleviate DOMS. Furthermore, natural supplements like ginger, tart cherry juice, and curcumin have demonstrated the potential to reduce inflammation and manage DOMS.

While pharmacological interventions may be considered for severe cases, the article underscores the importance of exercising caution due to potential side effects. In summary, DOMS management necessitates a holistic approach, combining multiple modalities and nutritional strategies to alleviate pain, enhance muscle recovery, and minimize the impact of this common condition on physically active individuals and athletes.

The test results on the proximity sensor are that the object is read by the proximity sensor when the object is 2 cm from the sensor, and if the object is metal waste then the servo motor moves 30 degrees to the right, if it is non-metallic waste then the servo motor moves 30 degrees to the left
Cyberbullying Among Tertiary Students: Self-Reported Prevalence And Nature Of Cyberbullying
Authors: Mohammed Rasheed Igbal,  , Ubaadah Bin Iqbaal,  , Neelam Hazoor  Zaidi,  , Shaista Snehal Kumar
Published: November 2023

Technology advancement and increased access to the Internet have led to a social disorder called cyberbullying. This study aims to discuss the self-reported prevalence and the nature of cyberbullying among tertiary students. Learning more about the social and economic implications of this occurrence is vital. College students' perceptions of cyberbullying and the learning settings they experience there. To investigate one facet of the nuanced interaction between university students and diverse media, this literature review looks at the following studies. What possible effects might educational and social media have on college students' mental wellness and well-being? Because cyberbullying offenders break societal norms and interpersonal standards, cyberbullying can be seen as unfair and abnormal behavior. Additionally, they violate the privacy rights of those who have been victimized, who unjustly endure the negative effects of cyberbullying that endanger their mental health and ability to succeed in school. Thus, it is also essential to create awareness to reduce the occurrence of cyberbullying and put an end to it.

Sleep is a fundamental physiological condition strongly regulated by a variety of neuroanatomical and neurochemical systems. Recent studies have indicated that catch-up sleep falls short of effectiveness to counteract the negative consequences of sleep debt however, the underlying mechanisms remain poorly understood. In this study, by using various transgenic fluorescent mouse models as well as techniques including intravital two-photon imaging and immunofluorescence staining of brain sections, we have documented morphological and functional changes of microglia during acute sleep deprivation (ASD) and subsequent short-term recovery sleep (RS). In these cerebral resident immune cells, we observed sustained microglial de-ramification, reduction of process motility and enhancement of microglial phagocytosis across brain regions. Given the intimate connections between microglia activity and neuronal plasticity, we also investigated synaptic plasticity and demonstrated an accelerated elimination of dendritic spines during both ASD and subsequent RS. Furthermore, untargeted metabolomic analyses revealed extensive whole-brain metabolic changes during ASD, and that a substantial number of metabolites and pathways failed to recover within a short period of RS. It is tempting to speculate that the disturbed cerebral metabolic homeostasis contributes to the sustained microglial activation and accelerated elimination of dendritic spines during this process. This study reveals the adverse effects of sleep loss on neuroimmunomodulation and neuronal plasticity, and implicates potential mechanisms underlying how irregular sleep schedules lead to neurological disorders.

Published: November 2023

Background: The number of options available to people with disabilities has gradually increased in Japan. At educational institutions where students with disabilities are enrolled, teachers must understand the various ways of life and provide appropriate guidance and support based on the actual conditions of individual students so that students can independently choose their career paths through self-selection and self-determination.

Objective: This study aimed to examine the effect of an intervention using a vocational assessment training program on eight teachers at a special needs school in Japan.

Methods: The level of knowledge and skills was assessed before and after the intervention. Intervention effects were analyzed through the Self-Assessment for Students and Counselors-Revised tool using the Wilcoxon signed-rank test, with corresponding samples for differences in mean scores before and after the intervention. In addition, the difference in the mean pre- and post-intervention scores for teachers with 10 or more years of upper secondary school experience (high experience group) and those with less than 10 years of upper secondary school experience (low experience group) was calculated.

Principal Verdicts: Indicated that the training program intervention helped teachers recognize the importance of vocational assessment and subsequently improve their teaching. Furthermore, the number of years of experience in upper secondary schools influenced the effectiveness of the intervention.

Conclusions: It was suggested that this training program would be effective for professionals who have acquired basic knowledge and skills in vocational rehabilitation.

Background: Academic stress and parental pressure have been shown to be important factors associated with psychological health. However, the internal mechanism between them is still not clear. Aim: This study assessed the joint significant influence of the predictor variables (academic stress and parental pressure) as predictors of psychological health in COVID-19 emergency times among school children with disabilities in Calabar metropolis, Cross River State, Nigeria: The implication for counseling. One study objective was stated, and one statement of hypothesis was posed. A literature review was carried out based on the variable under study. Method: The research design that was adopted in this study is correlational research design. A simple random sampling technique was adopted to select the 234 respondents sampled for the study from a population of 2,344. A validated 35-item four-point modified Likert scale questionnaire was the instrument used for data collection. The face and content validity of the instrument was established by experts in Test and Measurement. The reliability estimates 0.89 of the instruments were established using the Cronbach Alpha method. A multiple Linear regression statistical tool was used to test the hypotheses formulated for the study. The hypothesis was tested at a 0.05 level of significance. Results: The results obtained from the data analysis revealed that there is a joint significant influence of the predictor variables (academic stress and parental pressure) on psychological health in COVID-19 emergency times among school children with learning disabilities. Conclusion: Sometimes, stress and pressure can be motivating at the mild stage. However, at the severe stage, it could lead to frustration, social pressure, family workload, and cognitive overload, which in turn influences an individual to use and abuse substances in order to escape from unpleasant feelings of life situations. It was recommended that Parents should advise students on how to perform well academically rather than setting standards that may put so much pressure on students, which may have a negative impact on the psychological health of the students.
