ABSTRACT
Despite the restrictions caused by the COVID-19 pandemic and unfavorable foreign policy factors, tourism remains attractive to the population of many countries. The desire of a person to "move"in order to see something new, to feel what representatives of other cultures feel, is natural, in line with the logic of the historical development of peoples, and should be welcomed and encouraged at all levels of the state system. The transformation of travel into a mass phenomenon (including travel for tourism purposes) is largely due to almost revolutionary changes in the transport system. In modern conditions, the traveler is more focused on the independent choice of the tour, the alternative ways and means of transportation in an unfamiliar country. This imposes an additional burden on public transport, which must be taken into account when analyzing the potential of the transport infrastructure of the host country. In the main areas of analytical work, special attention should be paid to identifying social preferences of foreign travelers in the field of transport, determining priorities when choosing a travel method. In this regard, the following are relevant: a) the motives for choosing a mode of transportation / mode of transport by a tourist;b) the relationship of ethnic preferences and expectations when choosing a transport service;c) assessment of the emotional characteristics of the choice. Consideration of these issues and some conclusions obtained as a result of experimental work are presented in this paper. © 2023 EDP Sciences. All rights reserved.
ABSTRACT
Aim: This study aimed at the species identification of selected indigenous earthworms of Manipur and Assam, Northeast India along with an exotic species using morpho-anatomical study and DNA barcoding. Methodology: Indigenous species of earthworms were collected from Imphal and Jorhat, North-eastern part of India. The exotic species of earthworm were collected from Indian Council of Agricultural Research Complex, Manipur. The samples were collected by digging and hand sorting method. Identification of samples was done by both conventional and molecular methods. Molecular characterization was accomplished through PCR amplification of the mitochondrial cytochrome oxidase I (COI) genes. Automatic sequencing reactions were performed for the amplified PCR products on ABI3100 Genetic Analyser (Applied Biosystems). Result(s): Out of five specimens (EM1, EM2, EM4, EG5 and EM6) examined through morpho-anatomical studies, three were identified to species level while the other two were identified to their genus level only. Out of EM1 and EM2 specimens in the genus Perionyx as per the morpho-anatomical studies, DNA barcoding could deduce the EM2 specimen up to the species level as P. excavatus. The exotic EM6 specimen morphologically identified as Eisenia fetida showed 99% COI gene sequence similarity with both E. fetida and E. andrei but its sequence divergence with E. andrei was less than 1%, so, it belonged to E. andrei. Interpretation(s): This study shows the reliability of clubbing DNA barcoding experiments with classical taxonomy in supplementing and strengthening the traditional taxonomy for accurate identification of earthworms.Copyright © Triveni Enterprises, Lucknow (India)
ABSTRACT
A pandemic is defined by World Health Organization as an epidemic that occurs worldwide, crossing international borders and typically affects a huge number of people. Their impact in terms of health, economic and social consequences is disastrous. There have been a number of significant pandemics recorded in human history but their frequency and impact of emerging and re-emerging diseases have increased over the last few decades. There is no doubt that the world is changing rapidly due to globalization, climate change, disease outbreaks and the pandemic has exacerbated the condition. COVID-19 has already been established as pandemic among human and several vaccines, medicines as well phytochemicals are already in the market as immunomodulator to protect this. It has affected day to day life and is slowing down the global economy. The livestock sector is also not untouched and resulted in hardships to millions of poor livestock keepers. But, whether this segment will be doomed forever depends on our various coping strategies. Keeping this in view, the current review has been written to highlight the impact of COVID-19 in animal health, phytochemical developments as well as various impact on livestock sector.
ABSTRACT
Introduction: Coronavirus disease 2019 (COVID-19) pandemic, being a novel viral infection, has resulted in disruption of health services, including cancer patient's care and treatment. Hence, there was a need for testing and lateral integration of services for cancer patients with COVID-19. Materials and Methods: A total of 1178 samples were collected from cancer patients for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing before undergoing treatment in a tertiary care cancer center. The realtime reverse transcriptase polymerase chain reaction (RTPCR) was done using the E gene for screening, and for the confirmation, any of the three reactions using RdRp, ORF1bnsp14 and RNasePas were run as internal control. Results: Out of the 1178 samples tested, 211 (17.91%) were positive, and of these patients, 863 (73.25%) were men and 342 (29%) were women. Among the 863 men with cancer, 133 (15.41%) were real-time reverse transcriptase PCR (RT-PCR) positive. Of the 342 women with cancer, 78 (22.80%) were positive. Of the 144 SARS-CoV-2-positive cancer patients with cycle threshold (Ct) <25, 112 (84.2%) were asymptomatic and 32 (41.0%) were symptomatic. Sixty-seven patients showed positive results with a Ct >25. Out of them, 21 (31.3%) were asymptomatic and 46 (68.65%) were symptomatic cancer patients (P < 0.001). Of 144 patients with Ct <25, only 4 (2.8%) patients tested negative within 7-9 days, whereas the rest of the 140 (97.22%) became negative in >9 and up to 28 days. In the 67 cancer patients with Ct >25, within 7-9 days, 50 (74.6%) became RT-PCR negative and the remaining 17 patients mostly >60 years age group became RT-PCR negative in >9-28 days. Conclusions: Ct value of qualitative SARS-CoV-2 reverse transcriptase RT-PCR should be an important tool for an oncologist in designing and implementing patient management guidelines for SARS-CoV-2-positive cancer patients without or with symptoms for COVID-19.
ABSTRACT
Astaxanthin (ASX) is a xanthophyll carotenoid, naturally synthesized by Algae, Yeast, and bacteria. They are not just a powerhouse of antioxidant properties but also possess anti-inflammatory and other bioactive properties. Haematococcus pluvialis is the potential ASX source and shows powerful regulation on many health diseases. Over the decades, numerous studies have emphasized its importance in many human health diseases such as neurodegenerative disorders, cardiovascular diseases, Alzheimer, Parkinson, skin allergies, COVID-19, and many more. The present review discusses available evidence on the functional activities of ASX in various diseases and summarizes the potential factors involved in ASX response and highlights the potential implications. © 2021 Medhi and Kalita, et al.
ABSTRACT
The whole world is fighting against the pandemic situation created by the outbreak of COVID-19. Health workers, all over the world, are rendering service by putting their lives at stake. Health workers of Assam are also working relentlessly. This study attempts to analyse the role of the Accredited Social Health Activist or the ASHA workers of Assam in the fight against this pandemic situation. They have been serving the community to save it from this pandemic. They have faced a number of challenges while delivering their service. An attempt has been made in the current study to understand those challenges and to understand their side of the story.
