A Maximum likelihood (MLE) tree construction further confirms the separation of genomes into two distinct clades, BA. 1. and BA. 2. A very high reproduction number (R0) of 2.445 was estimated for the lineage BA.2. The highest R0 value in Telangana confirms the prevalence of lineage BA.2 in the state. Construction of the Reduced Median (RM) network shows evolution of some autochthonous haplogroups and haplotypes, which further supports the rapid evolution of omicron as compared to its previous variants. Phylogenomic analyses using maximum likelihood (ML) and RM show the potential for the emergence of sub-sublineages and novel haplogroups respectively. Due to the recombinant property and high transmissibility of omicron virus, we suggest continuous and more widespread genome sequencing in all states of India to track evolution of SARS-CoV-2 in real time.","PeriodicalId":11771,"journal":{"name":"European Journal of Biological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86068796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identification and detection of allergens play a critical role in the diagnosis and treatment of many allergic diseases. Aims were to determine the prevalence of most common inhaled allergens in Erbil province and determination the intensity of allergic response among allergic patients against 35 identified inhaled allergens items. A total number of 170 patients suffering from suspected inhalant allergy were checked in the present study. The study was carried out for patients who visited the private clinical sectors between 2018-2020 in Erbil province, Kurdistan Region of Iraq. Determination of specific IgE (sIgE) antibodies was examined for suspected patients. The country-specific inhaled allergy profile “Euroline inhaled Iraq 1” (Catalog no: DP 313816011 E, IVD approved, and CE certified EUROLINE immunoblot), containing strip for 35 different inhalant allergens, has been used in this study. Positive specific IgE to inhaled allergens was detected in 22.35% of our suspected patients. Orchard grass (21.05%) was the most inhaled allergen in our 38 allergic patients, followed by the Meadow foxtail (15.78%), Cockroach German and Sweet vernal grass (13.15%). Based on the present study results, we conclude that the prevalence of inhaled allergy differed between men and women in different age groups. Our study reached that there were no associations between inhaled allergens and sex or age. \u0000DOI: http://dx.doi.org/10.5281/zenodo.4395149","PeriodicalId":11771,"journal":{"name":"European Journal of Biological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81940100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The preliminary study of flood-affected crops was carried out in flood-affected cropland of Koshi Tappu Region of Eastern Nepal. For the experiment the plant residues of Eichhornia crassipes and Sesbania rostrata and inorganic fertilizer were selected to examine the growth and yield in Vigna unguiculata. The appropriate treatments for the production of V. unguiculata were analyzed. Before applying treatments, soil was collected and analyzed for physicochemical, microbial biomass and available nitrogen. Soil texture, soil moisture, water holding capacity and bulk density (BD) were calculated. The parameters such as soil pH organic carbon, organic matter and total nitrogen were determined. Soil microbe increases the significance of organic carbon and soil nitrogen is correlated for growth and yield. The results showed that the combined urea and plant residue increases the highest yield. And the Eichhornia compost represents the highest leaf area index and biomass. The total pod production was found in the Echhhornia compost. The dry weight per single pod in Eichhornia fresh was 7.82 g and in Sesbania fresh was 7.42 g. It proves that the land pattern is significant for the soil organic compounds. The experiment showed that the use of plant residues enhanced the increase of physicochemical properties of soil by adding the nutrients. The combined Urea + Eichhornia supports the best growth and development of the plant. \u0000DOI: http://dx.doi.org/10.5281/zenodo.4338159","PeriodicalId":11771,"journal":{"name":"European Journal of Biological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87190331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To insure their survival in hostile conditions where they face high competition with pathogenic microorganisms, they produce various kinds of bioactive molecules within biofilms with unique structural and functional features. As example: marine peptides which provide a broad spectrum of antimicrobial, antitumoral, antiviral and anti-inflammatory activities, in addition to marine exopolysaccharides showing antifouling and antifungal activities, immunomodulatory properties, emulsion stabilization capacity with other various potentials. Some biofilms have shown a beneficial role for aquaculture, among which enhancement of growth performance and improvement of water quality, while others are threatening not only aquaculture and maritime fields, but also medicine and food industry. Thus, marine bioactive compounds are promising preventing agents for the establishment and growth of fouling microorganisms, which may be useful in different fields in order to decrease economic losses and avoid foodborne illnesses.

Frogs were treated with chlorpyrifos for short and long term and sacrificed after 24, 48, 72 or 96 h in short term and after 5.10, 15 and 30 days in long term. Chlorpyrifos exposure provokes decrease in serum calcium levels after 48 h which persists till 96 h. There is slight decrease in the nuclear volume of UBG cells and cytoplasm depict weak staining response after 72 h. After 96 h these changes are more pronounced. PTG of Euphlyctis cyanophlyctis exposed to chlorpyrifos exhibit no change till 96 h. Serum calcium decreases on day 10 after chlorpyrifos exposure which continue to fall progressively till 30 days. After 15 days chloryrifos exposure, nuclear volume of UBG exhibit decrease and follicular epithelium displays decrease in height. Follicular epithelium after 30 days chlorpyrifos exposure reduces to the extent that it becomes single layered. Few degenerating cells have been discerned. At this interval nuclear volume of ultimobranchial cells exhibits a further decrease. PTG of chlorpyrifos treated frog depicts increased nuclear volume of PTG at 10 and 15 days. The nuclei of PTG are hyperchromatic and the gland becomes compact at 15 days. After 30 days following chlorpyrifos treatment nuclear volume exhibits further increase. Also degenerating cells make their appearance. Calcium regulating glands UBG and PTG of frogs were adversely affected by exposure to chlorpyrifos which may disturb the physiological functions of the organism. \u0000DOI: http://dx.doi.org/10.5281/zenodo.4004156","PeriodicalId":11771,"journal":{"name":"European Journal of Biological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77533315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the absence of stable treatments for COVID-19, the possibility that vitamins: B1, C, D, and E, omega-3, minerals (magnesium and manganese), and herb thyme may have unspecified effects on infection with COVID-19 would be considered. Various reports have revealed that vitamins B1, C, D, and E, omega-3, magnesium, manganese, and thyme may affect the human innate system, for example, thiamine may play beneficial roles in human immunodeficiency viruses (HIV), treating megadose ascorbic acid can assist prevent cold and flu symptoms, vitamin D can decrease the risk of developing COVID-19, vitamin E has been evaluated against the influenza virus in mice, and omega-3 fatty acids supplementation has been efficient in reducing the severity and frequency of sickle cell rate. Magnesium may be effective in patients with a mutation in the interleukin-2-inducible T-cell kinase, as well as manganese associates with the metabolism of glucose and fats, vitamin C, and B, accelerating protein synthesis, endocrine regulation, stimulating hematopoiesis, improving innate function, and reducing reactive oxygen species (ROS) generation. Moreover, thyme extract can have beneficial antiviral effects against human papillomavirus (HPV) and influenza A (IAV). The possibility that the vitamins B1, C, D, E, omega-3, magnesium, manganese, and thyme appear to affect the human innate system warrants further study, especially in light of the recent COVID-19 epidemic. \u0000DOI: http://dx.doi.org/10.5281/zenodo.3990659","PeriodicalId":11771,"journal":{"name":"European Journal of Biological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76629561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
