Urgent Prevention of Corona Virus Disease 2019 (COVID-19): Chinese Eating and Mask-Wearing Cultures

Abstract:

Chinese people have a very good mask-wearing culture; it is normal to wear masks to protect their faces from wind and pollution. Thus, they easily accept the wearing of masks to prevent infectious diseases, as seen with the Corona Virus Disease 2019 (COVID-19) in China today. However, Chinese people have a dangerous eating culture: they share foods or soups from the same bowls and pots using their personal chopsticks/spoons and emphasize loud talking when eating at banquets or at homes. We think this eating culture has raised the infection risk of COVID-19 from person to person by contamination. Therefore, in this paper, we propose models to elucidate how people are infected with COVID-19 through droplet transmission when eating with Chinese cultural context to address the urgent need to change Chinese eating culture; we believe these study models can help not only the Chinese people, but also other national people, to raise mindfulness of public health, prevent C...

Auricularia Polytricha (Mushroom) Regulates Testicular DNA Expression and Oxidative Stress Markers of Streptozotocin-Induced Diabetic Male Wistar Rat

Abstract:

Local Nigerian men have been using AuriculariaPolytricha as a treatment for sexual dysfunction without supporting evidence from scientific experiments. This study was to investigate the effect of ethanolic extract of A. Polytricha on testicular DNA expression and some oxidative stress markers using STZ-Induced diabetic rats as a model. The experiment included six groups, Group A (Normal Control, treated with normal saline), Group B (treated with 65mg/kg.bw of STZ), Groups C, D, and E (treated with 250mg/kg.bw, 500mg/kg.bw, 1000mg/kg.bw AP after inducing diabetics), and Group F (treated with 40mg/kg.bw metformin after inducing diabetics). The experiment lasted for 35 days. After termination of the experiment, Fuelgen nuclear reaction was used for DNA demonstration to assess testicular DNA distribution while serum Superoxide Dimutase (SOD), Catalase and Melondialdehyde where evaluated using reagent ...

Evaluations of phylogenetic proximity in a group of 67 dogs with osteosarcoma: a pilot study

Abstract:

The aim of this study is to analyze a group of dogs of different breeds affected by osteosarcoma (OSA), to document any prevalence of this primary bone neoplasia in breeds that are phylogenetically close and to help with further research human medicine, as a model of study for prevalence and epidemiology of human OSA in multiple populations.

Study of the Nanocomposite cBN/TiC-SWCNTs by Field Actived Sparck Plasma Sintering Process

Abstract:

Cubic boron nitrid (cBN) bonded TiC and alloyed with single walled carbon nanotubes (SWCNTs or NC) ceramics matrix nanocomposites (CMNCs) tools were manufacturated by a field actived sparck plasma sintering processus (FASPS). The effects of cBN-TiC ratio, carbon nanotubes and optimisation of the sintering process on the microstructure, densification in addition mechanical and vibronic properties of NC-cBN-TiC nanocomposites were studied. The results showed that for the nanocomposite cBN-TiC vol. ratio of 8:2 with 0.1 wt% NC, it was found that microhardness incresses significantly with addition of carbon nanotubes exhibited the highest microhardness and fracture toughness. After sintering of the samples at 1800 °C, 10 mn, 75 MPa of cBN–TiC_1-x, x=0.8 with and without addition of 0.1 wt% NC were characterized using field emission scanning electron microscopy (FESEM) an...

Micronutrients Analysis of Fresh and Canned “Agaricus Bisporus” and “Pleurotus Ostreatus” Mushroom Sold in Alexandria Markets, Egypt

Abstract:

Edible mushrooms form very nourishing meals especially for invalids, for they are easily digestible. They are consumed not only for their innate flavor and taste, but also for their important nutritional value, therefore, we analyzed the micronutrient contents of fresh and canned Agaricusbisporusand Pleurotusostreatus mushroom for their calcium, potassium and iron content. Fresh Agaricus was insignificantly higher in its calcium and iron contents (36.0 and 37.5 mg/100g; respectively) than Pleurotus(33.8 and 29.8 mg/100g) although the later was significantly higher in its potassium content (3890.4 mg/100g) versus 3102.9 in Agaricus. The micronutrient content of the canned Agaricus was higher than the canned cut Pleurotus. As these species of mushrooms are good sources of calcium, potassium, and iron, so they can be...

The Effect of 2,4 Dimethylamine salt on the Blood, Liver and Muscle of Oryclotagus Cuniculus

Abstract:

Aminoforce containing 720g/l of 2,4-dimethylamine salt induced changes on some enzymes and electrolytes in the male Oryclotagus cuniculus (New Zealand rabbit) were assayed. The organisms were exposed to varying sub-lethal concentrations of the toxicant (720g/l). The concentrations were prepared by pipetting 0.4mls, 0.8mls and 0.12mls making it up to 1.5L clean water in a metal container to make 2.0 mgl^-1, 4.0 mgl^-1 and 6.0 mgl^-1. Aspartate amino transferase (AST), Alanine amino transferase (ALT) and Acid phosphatase (ACP) were assayed in the liver and blood. Results showed that aspartate amino transferase values in the liver and blood were significant (p<0.05) across the concentration of the toxicants. Aspartate amino transferase increased as the concentration of the toxicant increased in the liver, and decreased as the toxicant concentration increased in the blood. Alanine amino transferase in the ...

Abstract:

Exposure of dichlorvos-contaminated foods, water and environment can lead to decrease in proper liver function. Thus, Mimosa pudica(MP)is being investigated in the present study to determine its protective effect on dichlorvos induced hepatotoxity in Mice.

Influence of Carbon - Nitrogen Supplements and pH on Growth of Sugarcane Stem rot Pathogen Fusarium Solani NVS671

Abstract:

Fusarium solani NVS671 identified from infected sugarcane stem of Co 671 as a new pathogen was subjected to various cultural conditions to understand its physiological profile. In continuation with our previous work, cultural analysis was carried out under in vitro condition by supplementing various carbon and nitrogen sources in Czapek-Dox agar (CDA). Under different hydrogen ion concentrations, it was found that the growth of Fusarium solaniNVS671 was less at pH 4 and pH 10 and could reach up to 5 cm after 7 days of incubation on Potato Dextrose Agar (PDA). It is observed that the pH around 7 to 8 was optimum for the growth of F. solani. Ten different nitrogenous (N) sources and nine different carbon sources were tested on CDA medium to know their effect on the mycelial growth rate and characteristics of the fungus. Among the N sources evaluated...

Analysis and Forecast Based on the Kinetic Equation for Changing the Numerical Composition of Living Systems

Abstract:

The possibility of applying the kinetic theory of aging of biological species published earlier by the authors of this work to assess and predict changes in the number of specific populations is evaluated. The populations of the USA, China and Russia, as well as the population of mice observed in the experiment "mouse paradise" of the American scientist John Calhoun are considered. To this end, a historically consistent analysis of the main previously proposed multi-scenario mathematical models describing demographic data and predicting the dynamics of the population was performed. The results of these models show a decrease in the population growth rate, a tendency toward a limit with an increase in historical time, the achievement of such a limit in some developed countries with a relatively high level of social security, a subsequent decrease in the number and further uncertainty of the final population outlook in the distant future. In addition, these models m...
