Authors: El-Fiky Fathy Kandeel
Published: September 2022

The essential oil EO obtained by hydrodistillation from the aerial parts of Pulicaria crispa was profiled using GS/MS analysis. The oil was found to contain carvotanacetone as a major component (81.9%). Biological investigation revealed that the oil possessed EC100 value of12.8 µl/ml in the in-vitro cytotoxicity assay against peripheral blood mononuclear cells (PBMCS). The oil showed no immune-stimulant activity. The antioxidant potential of the oil was assayed using DPPH radical inhibition resulting in inhibition percentage of 66.19% and trolox equivalent antioxidant capacity (TEAC) of 9.22µg/ml. The results indicate powerful antioxidant capacity of the oil, which makes it a good candidate to be used as a natural preservative or as a source of natural antioxidants to be incorporated in pharmaceutical applications. The cytotoxicity assay of the oil against colorectal“Caco-2” and hepatocellular “HepG-2” carcinoma cell lines showed IC50 values of 4.73 and 20.11 µl/ml, respectively. The obtained results spot the light on the colorectal anticancer potential of the oil, which should be subjected to future animal experimental study in form of enema.

Decoding Epigenetic Mechanisms as Vital Tools for Maintaining Pharmacological Potency of Herbal Medicines
Authors: Kimatu Josphert N
Published: September 2022

Studies have confirmed that heritable phenotypic variation in plants does not necessarily need to be based on the DNA sequence. Epigenetic studies have shown that the genomic DNA sequence might remain the same while gene expression changed by environmental conditions. This results in different morphologies and divers’ chemical products from same species of a plant. Thus, in this paper we highlight that the herbal medicine industry should always be considering the habitat of a plant and its growing conditions as it does affect the pharmacological potency of the metabolites produced. The various aspects studied in this paper show that there is a need of optimizing the production sites of herbal medicinal plants because ecological factors influence epigenetic gene expression changes. This eventually affects the quality, quantity and efficacy of the secondary metabolites or drugs synthesized by the plants. Traditional herbalists have learnt this phenomenon by experience. Therefore, the value and exploitation of herbal medicine for modern human maladies shall greatly benefit by understanding the ecological influence of epigenetic mechanisms on medicinal potency.
Narrative Review: Phytocannabinoids and their Potential Use as a Phytochemotherapy
Authors: Panichayupakaranant Pharkphoom
Published: September 2022

Cannabis sativa L. has been used as an herbal medicine for centuries. This plant is a natural source of cannabinoids, including Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), the two major phytocannabinoids that have been a recently interested research topic on their therapeutic properties. The human endocannabinoid system generally consists of receptors, endogenous ligands, and metabolizing enzymes, and plays an important role in various physiological and pathological effects. Based on cancer therapy, phytocannabinoids have mainly been used for palliative care treatment, i.e. relieving nausea and vomiting caused by chemotherapy and stimulating appetite. Additionally, in many preclinical experiments, including in vitro and in vivo studies, cannabinoids have exhibited anticancer effects against numerous cancer cell lines through various mechanisms. For example, THC induced apoptosis of cancer cells via cannabinoid receptors by a stimulation of ceramide synthesis led to an activation of the endoplasmic reticulum stress-related signaling pathway, and the induction of autophagy through a calmodulin-activated kinase kinase β. In contrast, the anticancer activity of CBD is related to other types of receptors, i.e. orphan G-protein coupled receptor 55 (GPR55), transient receptor potential vanilloid receptor 1 (TRPV1), transient receptor potential melastatin 8 (TRPM8), which mainly relied on the stimulation of reactive oxygen species (ROS) production, leading to induced cancer cell death. Although, there are many reports on anticancer properties of phytocannabinoids, in vitro and in vivo, high quality clinical trials concerning their efficacy and safety are still essential to approve their potential use as a phytochemotherapy.

The Grand Lemurrian Siva Sakthi Maha Mudra
Authors: S Kalimuthu
Published: September 2022

The substratum of the Vedas and the Upanishads is that Lord Shiva is static and his counterpart Paarvathi who is also called Sakthi is His consort. It is generally believed that Lord Shiva is Adi Yogi. In the Indian Santana Dharma which also called Truth the yogic practices are inseparable and also indispensable. That is the marvelous beauty of yogic techniques. That’s why in the great Indian epic Mahabharata Lord Krishna tells Arjuna that He created this Universe with His Yoga Maya. All the Indian traditional spiritual knowledge were transmitted and taught to the Seers by Lord Shiva. The yogic asanas help the performers to sit properly for meditation. Prayer is outward appeal to Gods and Goddesses whereas the meditation is PURELY inner travelling. Prayer requires a deity but meditation does not need any Gods. The proper meditation leads the practitioner to Nirvikalpa Samadhi. In the Indian spiritual systems there are hearing, studying, watching and learning. Reading and learning are not at all similar or identical. The main thing is that even learning is not sufficient to attain spiritual peace, bliss and enlightenment. Some meditations are difficult to perform. In this work, the author unlocks the mysteries and instant benefits of the Grand Lemurriaan Siva Sakthi Maha Mudra which was kept very secret by the Sages till this day

Do Individuals Living with HIV know how to Access Resources in Order to Safeguard their Health in the Event of Statewide Emergency Situations?
Authors: Downer Goulda
Published: September 2022

There has been a significant increase in the number and severity of disasters over the past decades as is noted in the Centre for Research on the Epidemiology of Disasters’ Emergency Events Database (EM-DAT). Access to care during such events is critical for vulnerable populations, especially those with communicable diseases such as HIV. As such, inability to access antiretroviral medications, safe food, housing, and transportation may disproportionately affect People Living with HIV (PLWH). This is especially so, because PLWH are both more likely than the general population to experience adverse effects from disasters and face multiple stigmatizing barriers to care. Methods: A cross-sectional survey was self-administered to a convenience sample of 53 volunteers who were in attendance at a World AIDS Day event in Washington, DC. This pilot study utilized scenarios to examine what PLWH would do if they ran out of medication and food in the event of an emergency situation such as a natural disaster or catastrophic event. The survey also asked about PLWHs’ housing and transportation concerns in emergency situations. Results: Analyses revealed that all areas assessed would pose a difficulty for PLWHs. Furthermore, inability to access medication (88%) and the lack of knowledge about how to access medication (92%) during a natural disaster were consistently stubborn issues. Conclusions: Findings suggested that this cohort of PLWH in DC might not be prepared for emergencies. Similarly, they do not know where to access the assistance needed to prevent health complications during emergencies and disaster situations. The results highlighted some reasons for vulnerability of PLWH in this geographical location. More planning and education are needed to safeguard the wellbeing of PLWH, lessen PLWH’s health vulnerabilities, and enhance supportive services for PLWH and their caregivers during emergency or disaster situations. Significant implications are discussed for future prevention, intervention, practices, and research as the nation moves to address the goal of “Ending HIV by 2030.”

Authors: Arintoko Arintoko
Published: September 2022

This study aims to estimate the impact of monetary policy shocks on inflation, output, and exchange rates during the inflation-targeting period. The data analyzed are quarterly data covering the period 2005Q3 - 2020Q1. The analysis tool used is the Vector Error Correction model with the cointegration relationships between variables. The results show that there are variations in the impact of the monetary policy shock on the response of the variables in the model. Monetary policy shocks can explain the forecast error variance of policy interest rates, inflation, exchange rates, and output, respectively, with the largest to the smallest contribution. The characteristics of shocks are unexpected and unpredictable, resulting in variability and volatility of the variable responses. Therefore, reducing the impact of the monetary policy shock can improve the effectiveness of the monetary policy. Improving the effectiveness of monetary policy can be done with the support of the central bank's credibility.

Post-structurally and didaktically informed teaching arrangements in preschool – exemplified by “rhythmatechs” as multivocal teaching
Authors: Holmberg Ylva Carolina , Vallberg-Roth Ann-Christine
Published: September 2022

The article is based on a sub study in an R&D programme in which participants try out a didaktically and post-structurally informed teaching arrangement. The article is guided by the question What can characterise the “what”, “how”, and “why” questions of teaching from the standpoint of a post-structurally and didaktically informed teaching arrangement in the preschool? The substudy is based on material consisting of 251 documents, including co-plans, videos (5.5 hours) and photo documentation, as well as co-assessment. A didaktical oriented abductive analysis was carried out. The results pave the way for the content combination offered by the concept rhythmatechs (rhythmics-mathematics-technology) as a multivocal alternative to more subject-focused teaching. Within the framework of project- and theme-oriented working methods, the content appears on the one hand to be both transdisciplinary and interdisciplinary, and on the other hand, to represent specific content areas, such as science, mathematics, and music. We tried out a didaktik model that combines the didaktik triangle with didaktik questions “what”, “how” and “why” with the didaktik triangle. The model stands in relation to results that focus on inter- and/or transdisciplinary content, in project- and theme-oriented approaches, and selection of content as goals and/or means.

Background: During the COVID-19 pandemic, there was a tremendous expansion in the Internet and technology and social distancing, which increased the usage of digital devices more than before. This puts people at a higher risk of getting digital eye strain (DES) symptoms especially dry eye. This study aimed at evaluating the association between DESsymptoms, especially dry eye, and the online study during the COVID-19 pandemic among medical students at Qassim University, Qassim, Saudi Arabia.
Methods: A cross-sectional study was conducted among 340 medical students at Qassim University, Saudi Arabia. A self-administered online questionnaire was distributed among medical students.
Results: The present study showed a significant difference between usage duration before and during the lockdown. Digital device use for more than 10 hours per day was reported by 67.4% of the medical students 57.1% were male students. Chi-squared analysis indicated most symptoms are associated with the usage duration. The overall prevalence of DES was 92.6%, and the most notable symptoms that increased during the pandemic were those related to eye dryness (43.5%). Moreover, the most frequently used device daily was the smartphone (90.6%) and tablet (71.2%).
Conclusion: The use of screen-based technologies has become a necessity of modern life, notably during and after the COVID-19 pandemic, which led to a serious dependence on them and an increase in the prevalence of DES symptoms, particularly eye dryness. It is important to raise awareness about DES symptoms, including dry eye associated with long use of digital devices and the measures to protect ocular health by limiting screen time use, following the 20-20-20 rule, using lubricant eye drops and protective glasses.

Wild Relics in an Urban Landscape
Authors: Luther Erin
Published: September 2022

As global urbanization gains momentum, human experience is increasingly restricted to dense urban environments; a new urban human looks out through the window, rejecting and inviting the "wild" in complex ways. This paper analyzes a sampling of newspaper articles that probe the dimensions of the urban wild by following the media intersection between humans and a commonly encountered wild animal, the raccoon. This intersection is typical of many urban human-wildlife interactions in the sense that it is characterized by a fierce ambivalence (Griffiths, Poulter, & Sibley, 2000). The human-raccoon relationship, however, captures this ambivalence in a way not seen with other urban wildlife. Conflicted feelings about raccoons challenge the psychic boundaries of both human and animal domesticity in an urban context.
