Transcriptomic information provides fundamental insights into biological processes and can be used to determine gene expression in cell, tissue, or organism under specific physiological conditions, or in response to any environmental perturbation. Extraction of high quality RNA is a challenging step mainly in non-traditional organisms, and protocols for preservation and isolation need to be adjusted in many cases. In the present work, we aimed to develop a protocol for preservation and isolation of high-quality and quantity of RNA from blood and liver tissues of Caiman latirostris. Three preservation methods were tested: 1) flash freezing (LN2) and storage at –80°C; 2) RNAlater® conservation with progressive cooling up to –80°C); 3) preservation in TRIzol® reagent, flash freezing in LN2 and storage at –80°C. Methods 1 and 2 were tested for liver, while 2 and 3 for blood. Our results showed that both preservation methods resulted in excellent outcomes for liver samples. For blood samples however, TRIzol® preservation was an efficient procedure for adequate RNA quality, quantity, and integrity, while conservation in RNAlater® solution was inadequate in both quality and quantity for an optimal RNA extraction. Appropriate protocols were established for each tissue and are being used now for transcriptomic studies in this sentinel organism.

Mongolia ranks third in the world in stroke-related deaths. Loss of skeletal muscle mass and function, known as sarcopenia, is associated with a higher risk of various metabolic disorders such as stroke. Thus, screening of sarcopenia is important. Hand-grip strength (HGS) can be used to predict sarcopenia in the short term. In this cross-sectional study, we used data (n=1180, mean age of 39.2 ± 15.2 and 33.2% males) from the Mon-Timeline cohort study, a multidisciplinary, prospective, population-based cohort study in Mongolia. A digital grip strength dynamometer (TKK 5401 GRIP D; Takei, Japan) was used to measure HGS. We performed binary logistic regression analysis between HGS and stroke risk. Suspected sarcopenia was defined when HGS is less than the 25th percentile of HGS. In this study, 3.3% of all participants had a stroke. The incidence of stroke was significantly higher (5.2% and 1.9%) in people with suspected sarcopenia. According to body composition, the incidence of stroke was more frequent in sarcopenic obese people: 1.3%, 2.4%, 2.8% and 6.2% in normal (non-obese and non-sarcopenic), sarcopenic (non-obese), obese (non-sarcopenic) and sarcopenic obese groups, respectively. In regression analysis, the OR (95% CI) was 2.84 (1.44; 5.59) for sarcopenic compared with non-sarcopenic. The adjustments for age, gender, education, body mass index, waist circumference and hypertensive status attenuated the associations, but lower HGS remained significantly associated with a higher risk of stroke. In conclusion, lower HGS was significantly associated with a higher risk of stroke independent of adiposity and hypertensive status in Mongolian adults.

Purpose of the study.To investigate the features of lesions of the gastrointestinal tract in diff erent variants of the course of COVID-19 in children.

Materials and methods.A single-center prospective study was carried out to study the clinical and laboratory manifestations of gastrointestinal tract (GIT) lesions in different variants of the course of COVID-19 in children. The study was carried out in the following groups: group No. 1 — pediatric patients with a verified diagnosis (according to ICD 10) “U07.1. COVID-19 virus identified, confirmed by laboratory tests, regardless of the severity of clinical signs or symptoms ”, n = 524; group No. 2 — pediatric patients with a verified diagnosis (according to ICD 10) “U10.9 Multisystem inflammatory syndrome associated with COVID-19, unspecified”, n = 46. The article provides a brief description of the observations of the development of autoimmune pathologies (ulcerative colitis, autoimmune hepatitis) in pediatric patients, for whom a postponed COVID-19 infection could be a probable trigger.

Results.The leading symptoms of the gastrointestinal tract in patients of group No. 1 were symptoms of acute gastroenteritis, registered in 37.6% of cases. Diarrhea was detected in 21.2% of cases, vomiting — in 16.5%; abdominal pain syndrome — 9.2%. These manifestations were statistically more significant in patients under one year of age, as well as in children of the first three years of life (p≤0.05). Gastrointestinal syndrome in patients of group No. 2 was registered in 67.4% of cases, with vomiting — 60.9% of cases, diarrheal syndrome — 23.9% of cases, abdominal pain syndrome — 82.6%. Other manifestations of the gastrointestinal tract in patients of this group were: reactive hepatitis — 69.6% of cases (average ALT — 98 (47; 347); AST — 107 (34; 347)), reactive pancreatitis — 60.8% of cases (average values of amylase — 127 (28; 269); lipase — 196 (47; 107)). These lesions were of a reactive inflammatory nature, with a probable immune development mechanism.

The aim of the study is the evaluation of results of endoscopic tunnel interventions in submucosal tumors and achalasia.

Material and methods. Endoscopic tunnel interventions during 2017–2020 years were performed in 80 patients (34-men, 46-women). The duration of the age ranged from 15 to 72 years. The indications for interventions were: achalasia in 53, subepithelial tumors in 27.

Results. During the intervention, complications occurred in 22 patients. Among the complications: carboxyperitoneum in 16 cases, carboxytorax in 2, esophageal mucosa perforation in 2, bleeding moderate intensity bleeding in 2. Most of the complications (20) were in patients with esophageal achalasia. Postoperative complications were observed in two patients operated for esophageal achalasia (bleeding and hematoma, esophageal mucosa necrosis). All patients were treated by using conservative methods. The results of the interventions were assessed in terms of 1 month to 3 years. There were no violations of food or liquid the passage through the cardia. Patients after operation for submucous tumors of the esophagus had no complaints. The main complaint of patients after myotomy was heartburn. Endoscopic examination revealed erosive reflux esophagitis (A-C) in 18 patients.

Conclusion. Tunnel endoscopic interventions in patients with esophageal achalasia and submucous tumors are highly effective and low-traumatic, allowing relatively safe restoration of the patency of the cardia and removal of the subepithelial neoplasm. The problem of gastroesophageal reflux after oral endoscopic myotomy requires further accumulation of data in order to develop optimal tactics. The limiting factor for the these operations performance is the material and technical equipment of medical institutions and the lack of trained specialists.
Recovery strategies intestinal mucosal barrier

The surface of the intestinal tract in healthy people is free of bacteria in all segments of the intestine. Thus, the attachment of bacteria to epithelial cells is a sign of infection. Unlike the mucous membrane, the intestinal lumen is never sterile. The reason for this is the polymicrobial nature of the gut microbiota. In the intestine, segments such as the stomach or small intestine, where bacteria are actively suppressed, the microbiota is random in appearance, composition, and concentration. However, the situation is completely different in the colon, where the growth of bacteria increases and their suppression is suspended. The concentration and diversity of bacteria in the colon reaches astronomical numbers. Some of these bacteria are required for the colon to function. Many of the local bacteria in the colon are potential pathogens: Bacteroides, Enterobacteriaceae, Enterococci, and Clostridium histolyticum. Control of pathogens in the colon is achieved through an impenetrable mucus layer. Inflammatory bowel disease is a polymicrobial infection characterized by persistent disruption of the mucosal barrier, subsequent migration of bacteria to the mucous membrane, and overgrowth of a complex bacterial biofilm on the surface of the epithelium, resulting in invasive and cytopathological effects. As long as the mucosal barrier function is impaired, the inflammatory process cannot successfully remove bacteria from the mucosal surface, and inflammation itself is detrimental. Due to the inflammatory reaction, the composition and structure of the fecal microbiota changes. Based on the biostructure of the fecal casts, active Crohn’s disease and ulcerative colitis can be distinguished from each other and from other gastrointestinal diseases. The relationship between the gut microbiome and various dermatological diseases (psoriasis, acne, rosacea, atopic dermatitis) is discussed.
Differential expression of lipoma HMGIC fusion partner-like 3 in human epithelial ovarian cancer.
Authors: Mamoor Shahan
Published: September 2021

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding lipoma HMGIC fusion partner-like 3, LHFPL3, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. LHFPL3 expression was significantly lower in high-grade serous ovarian tumors relative to normal fallopian tube. LHFPL3 expression correlated with progression-free survival in patients with p53 mutant ovarian cancer. These data indicate that expression of LHFPL3 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. LHFPL3 may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.
Worldwide moderate-resolution mapping of lake surface chl-a reveals variable responses to global change (1997-2020)

Published: September 2021

Anthropogenic activity is leading to widespread changes in lake water quality--a key contributor to socio-ecological health. But, the anthropogenic forces affecting lake water quality (climate change, land use change, and invasive species) are unevenly distributed across lakes, across the seasonal cycle, and across space within lakes, potentially leading to highly variable water quality responses that are poorly documented at the global scale. Here, we used 742 million chlorophyll-a (chl-a) observations merged over 6 satellite sensors (daily, 1 to 4 km resolution) to quantify water quality changes from 1997 to 2020 in 345 globally-distributed large lakes. Chl-a decreased across 56% of the cumulative total lake area, challenging the putative widespread increase in chl-a that is expected due to human activity. 18% of lakes exhibited both significant positive and significant negative chl-a trends across different locations or times of the year. This spatiotemporal complexity demonstrates the value of moderate resolution mapping of lake chl-a to inform water management decision-making and to determine the local ecological consequences of human activity.
Market Segmentation Analysis in Tourism: A Perspective Paper
Authors: Dolnicar Sara
Published: September 2021

No two tourists are the same. This insight stands at the core of market segmentation. Pursuing a segmentation strategy as a tourist destination or a tourism business means catering to the specific needs of certain types of tourists (market segments), rather than attempting to satisfy the needs of the entire tourist market by effectively targeting the average tourist. But which market segments should a tourist destination or business target? Market segmentation analysis helps answer this question. Market segmentation analysis is “the process of grouping consumers into naturally existing or artificially created segments of consumers who share similar product preferences or characteristics” (Dolnicar, Grün & Leisch, 2018, p. 11).

Published: September 2021

Amenity clusters that consist of coffee shops, restaurants, and other small businesses provide utility to urban life and jobs for city dwellers. While most small business clusters were hard hit by the restrictions imposed during the COVID-19 pandemic, others were able to adapt. What determines the economic resilience of amenity clusters? By using store-location data for Seoul during 2016-2021, we identify spatial clusters of amenities and an \textit{amenity space} to examine the effect of relatedness on the resilience of each cluster. We find that businesses are more likely to survive when located in clusters of related amenities.

Awareness and prevalence on computer vision syndrome among medical students: A cross-sectional study
Authors: Garg Sughandha , Mallik Debayan , Kumar Arun , Chunder Rajasri , Bhagoliwal Ajay
Published: September 2021

Background: Computers have significantly impacted cognitive, social, physical and various other aspects of the modern daily lives of computer users, especially among internet users. Our life is inseparable from the internet, e.g., chatting, online shopping, gaming, video conferencing, and emailing. In the modern day, nearly every job is done sitting in front of a computer. Majority of the day is spent on the computer either working or for recreational purposes. Consequently, the effects of computer use on eyes and vision has increased too. This study will review the factors relating to eye and vision problems amongst students and its association with computer work and provide recommendations for preventing or reducing their development.
Aims and Objectives: The aim of the current study was to estimate the prevalence of computer vision syndrome, its knowledge and application among medical students.
Materials and Methods: This was a cross-sectional study, which was carried out amongst the MBBS students (1st, 2nd and 3rd year) of Rama Medical College Hospital and Research Center, Kanpur, India. The data was collected between January 2017 to March 2017. Students who gave their consent were taken up for the study. A pretested, semi-structured questionnaire was used to collect the data.
Results: A total of 214 medical students participated and majority of them were below 22 years of age. The prevalence of Computer Vision Syndrome was found to be 83% [95% CI = 67.9% - 91.6%]. More than 70% students spend up to 4 hours in front of computer. Roughly 40% knowledge of Computer Vision Syndrome, but only 10% took any measures to prevent the disease. And those who had symptoms experience them within 2-3 hours of computer use. Majority of them complained of having watery eyes and blurred vision.
Conclusion: A significant proportion of students do manifests Computer Vision Syndrome and denotes that the health of the people working on the computers should be emphasized as a field of concern in public health. These are young kids and having this syndrome so early in life will have a detrimental effect on their health in future. Hence the stakeholders involved, needs to be sensitized regarding the importance of the regular eye and health check-ups and proper rest to the eyes. Further research is recommended to know the depth of the problem as it has the potential to become a modern-day pandemic.

Aims and Objective: To relate the meaning of sputum cytology and fine needle goal cytology of bronchial tissue under CT rules for diagnosing cellular breakdown in the lungs.
Materials and Methods: This potential observational investigation was completed by the division of medication in Chattogram Medical College Hospital, Chattogram, Bangladesh. Where data was collected from January 2019 to June 2020. A total of 50 patients with a suspected history, symptoms, and risk profile of having primary lung cancer, as demonstrated by chest radiography and CT scan, were chosen for the research population. Fifty patients with clinical and biochemical verification of suspected. All collected data were coding and input in SPSS-25 for further analysis. Both descriptive and inferential statistics were tested.
Results: Among the 50 patients the vast majority of the patients were 51-60 years of age and the biggest number of the (94 %) patients were male. Sputum cytology is 8% touchy which isn’t steady with different examinations and CT guided FNAC is 94% sensitive.
Conclusion: A definitive point of picture guided histological or cytological examination is to stay away from unnecessary thoracotomy and accomplish a particular determination with sensible exactness and least results. So, in this examination we found that sputum cytology is 8% delicate which isn’t steady with different investigations and CT guided FNAC is 94% touchy to last histological analysis of lung cancer. The discoveries recommended that CT guided FNAC discovered to be protected, feasible and viable.

Published: September 2021

Background: Obesity and its’ comorbidities in young adults are emerging health concerns. Obesity is a well-known risk factor for developing cardiovascular diseases, type -2 diabetes, carcinomas, gallbladder disease, sleep apnea, osteoarthritis, and gynecological complications. Young adulthood is considered the best time period to introduce weight control interventions as the established lifestyle behaviors may persist throughout life.
Aims and Objectives: The present study assessed self-perception of body weight, knowledge and practices on obesity and weight reduction and their associated factors in a sample of treatment seeking obese young adults.
Materials and Methods: Two-hundred and sixty-one obese (BMI ≥ 25 kg m-2) young (18-35 years) adults attending an out-patient nutrition clinic of a teaching hospital in Sri Lanka were studied. An interviewer administered questionnaire was used to collect demographic data and information on body weight perception and, knowledge and practices on obesity and weight reduction. Weight, height and waist circumference were measured.
Results: The mean (±SD) BMI of the participants was 29.0 (±3.6) kg m-2. Only 16.1% precisely perceived themselves as ‘obese’ and increased BMI was only significant predictor of accurate body weight perception (OR=1.23; 95% CI=1.07-1.47; p=0.003). Only 49.0% reported obesity as a disease and 46.0 % and 27.2% that it predisposes to stroke and carcinoma respectively. Although 86.2% have attempted weight reduction, only 33.8% sought professional advice. Diet control was the most common weight reduction strategy (73.1%) and among them 33.3% combined with exercises. One fourth (n=56) relied on green tea for weight reduction and meal skipping was reported in 52.9%.
Conclusion: Significant body weight misperception was reported in lower BMI categories. The overall knowledge regarding obesity and weight reduction was satisfactory though not optimum. Diet control with or without physical exercises was the most popular method of weight reduction.

Background: The first case of COVID 19 illness was detected on 31st December 2019 and the disease has progressed globally causing significant morbidity and mortality. The disease initially thought to be a respiratory virus soon showed manifestations involving other systems and diagnosis and treatment of the disease became more complicated.
Aims and Objective: This study aims to derive a scoring system based on health records of patients suffering from COVID 19, to help in early triaging of the illness and therefore allowing for early institution of treatment. To establish a scoring system inclusive of clinical, laboratory and radiological parameters to assist in the prognosis of patients afflicted with COVID 19 illness.
Materials and Methods: Health records of 138 COVID patients has been included in the study. The scoring system comprises of parameters including Age, Co-morbidities, Shortness of breath, Saturation, Pulse Rate, Respiratory rate, temperature, D dimer, Neutrophil Lymphocyte ratio, Troponin I, Organ involvement, Radiology. The cumulative scoring ranges from 0-16. The mortality rate among the subjects included was 25.4%.
Results: All parameters involved were found to be independent risk factors for mortality. Patients were effectively categorizedbased on the scoring system and mortality found to be associated with increasing scores. This model displayed good discrimination (AUC =0.875) and the sensitivity and specificity of the model was found to be 0.857 and 0.767 respectively.
Conclusion: This scoring system has been designed to categorize based on the systemic involvement of the disease and thus would serve as a reliable indicator for prognostic assessment in patients.

Authors: Taia Wafaa Kamal , Helme Zayed Ahmed Adel
Published: September 2021

Background: Folk Egyptian medicine considered from the most important source of the use of wild plants in medication. Wild plants are considered a perfect source of natural compounds that have been used as antimicrobial andante virus activities.
Aims and Objective: The aim of the current study was to investigate the effect of the commonly used wild plants in the treatment of jaundice and they effect on HAV. This article provides much-needed insight into the effect of wild plants on the hepatitis A virus to shed more light on the important subject, which is unfortunately poorly investigated.
Materials and Methods: In this investigation, the aqueous plant extracts of twenty-five wild Egyptian species, 16 perennials, and 9 annuals; three concentrations, 1%, 3% & 5%; were tested for HAV replication by using PA and PCR techniques. Questionnaires and interviews with Bedouins have been carried to know the most used species in the treatment of jaundice, and the usage values were calculated. Those species were collected from their habitats, rare ones purchased and reviewed their identifications and used in this work. Fecal and blood samples were taken from 9-10Y old patients, 35 girls and 25 boys.
Results: The PA test revealed that 16 species out of twenty-five gave positive results, while the rest of the species gave negative results on Vero cells. Twelve of the sixteen species were perennial species, and the rest are annuals. The Plaque assay results showed that the most effective aqueous extract species, with the three concentrations, on HAV activity were those of Salvia verbennaca, Mentha microphylla, Ocimum basilicum, Cassia senna, Solenostemma argel, and Thymus capitatus, respectively. PCR test has been carried for the first three species and gave very faint nucleic acid tapes, which means that the plant extract of these species, the three concentrations, minimize the virus activity by a way or another. Samples from the patients tested for the antibodies for IgM and IgG using the ELISA test. Within both the females (58%) and males (42%), 6% have positive antibodies for IgM, while 36% in females and 34% in males’ have positive antibodies for IgG and 8% females and 10% males have both antibodies (IgM & IgG).
Conclusion: Wild plants, especially those with essential oils can tolerate the Hepatitis A virus (HAV) activity and reduce its symptoms.
