An Assessment to Human Perception to the Origin of Coronavirus by the Impact of Climate Change and Preventative Management of Pandemic Coronavirus COVID-19

On 12 January 2020, the WHO confirmed that a novel coronavirus was the cause of a respiratory illness in a cluster of people in Wuhan City, China. The aims of the study to assess the human perception to the origin of Coronavirus with relation to nature and find out preventative management about coronavirus. Primary data was collected for analyzing some factors regarding the Coronavirus microorganism formed by the impact of climate change. Primary data was collected through an online questionnaire survey. An online questionnaire survey is used for human perception for taking public opinion about the origin of Coronavirus and preventative management which are conducted in Bangladesh. SPSS software is used for Linear Regression analysis and correlation with some variables. A total of three variables were considered in the model estimation of which are dependent variables Coronavirus microorganism formed by the impact of climate change and independent variables such as Coronavirus microorganism formed by the impact of environmental pollution, Coronavirus microorganism formed by the impact of global heat and Coronavirus microorganism originated by the sources of the impact of ice melting polar region. From the analysis, it is found that the Coronavirus microorganism formed by the impact of climate change that makes a unique and statistically significant contribution to the prediction. Among 200 respondents, about 70% of peoples said “Maybe” Coronavirus microorganism formed by the impact of climate change, and it’s some factor. It is also found from the correlation analysis that the epidemic effects of COVID-19 will high on Bangladesh, if immigrant persons come, if Curfew doesn’t issue, if peoples are not conscious, if peoples are not properly using mask and hand gloves, if they are not maintaining social distance and lock down rules. In the finding that, in the polar region, there are many ice stacks where thousands of years ago, the animals are dead but the virus and bacteria are in a state of sleep. As the heat increases, all glaciers and permafrost start to melt in the Polar region. As a result, many types of viruses, bacteria are starting to live. These viruses including Coronavirus will be mixed with different environmental elements such as water, biodiversity. This will easily affect biodiversity and other animals including humans. Above all Climate change may play a significant role in the transmission of many infectious diseases including Coronavirus. Community responses are important for outbreak management during the early phase of major preventive options

Morphological and physiological variation among different isolates of Alternaria spp. from Rapeseed-Mustard

To find out the Morphological variation on growth and sporulation of Alternaria species of Alternaria leaf blight of mustard from 10 representative geographical locations of Bangladesh, this experiment was conducted at Plant Pathology Laboratory, Oilseed Research center, Bangladesh Agricultural Research Inistitute (BARI), Joydevpur, Gazipur, Bangladesh. All the isolates showed high level of variability in in-vitro in respect of radial mycial growth, colony colour, sub surface colour, colony shape, colony texture, zonation (surface and sub surface), length and width of conidia, beak length and number of septa. The maximum and minimum radial mycial growth was recorded 90 mm in isolate NATAb and 83.67 mm in isolate GAZAb, respectively at 14 days after incubation. Significant variation in conidial length, width, beak and no. of conidia observed in all isolates. The length of conidia ranged from 41.56 to 117.54µm with 3 to 11 transverse and 0 to 3 vertical septa. The width and beak length varied from 10.34 to 23.12 µm and 16.78 to 72.65 µm ,respectively. Surface colour were olivacious green to black and circular shaped colonies were observed in all isolates on PDA medium. Colony texture were cottony to velvety. Subsurface colour varied from light brown to black and pinkish. Zonation found in some isolates and some did not produce on both surface and subsurface. All conidia were murifrom and light brown to deep brown in colour. Potato Carrot Dextrose Agar medium (PCDA) and 25 o C temperature were found optimum for different isolates for mycelial growth and sporulation

Association between Helicobacter pylori infection and primary open-angle glaucoma

The pathological processes of primary open-angle glaucoma is unknown. Several studies show the relation between Helicobacter pylori infection and primary open-angle glaucoma. The purpose of this study was to assess the association between H. pylori infection and primary open-angle glaucoma. Forty patients of diagnosed primary open-angle glaucoma were selected as case and 40 participants without primary open-angle glaucoma were selected as control as per inclusion and exclusion criteria. Complete clinical evaluation including history, physical examination, relevant ocular examinations and laboratory investigations were performed. Serologic evidence of H. pylori infection was found in 75% of patients with primary open-angle glaucoma and 30% of patients without primary open-angle glaucoma which achieved statistically significant difference (p=0.000, OR=7.00 and CI 95% =2.61-18.74). 13C urea breath test was positive in 70% in case group and 37.5% in control group which also achieved statistically significant difference  (p=0.003, OR=3.89 and CI 95% =1.53-9.87). The findings revealed significant association between H. pylori infection and primary open-angle glaucoma.

Nanoemulgel: For Promising Topical and Systemic Delivery

Nanoemulgel delivery system is a fusion of two different delivery systems, wherein the physical state of drug containing nanoemulsion is changed by adding it to the gel matrix, thus enabling more lipophilic drugs to be used in treatment therapies. It solves the major issues such as limiting use of lipophilic drugs, poor oral bioavailability, and unpredictable pharmacokinetic and absorption variations. Simultaneously, its nongreasy nature and easily spreading ability support the patient compliance. Nanoemulgel can be widely used in the treatment of acne, pimple, psoriasis, fungal infection, and inflammation cause by osteoarthritis and rheumatoid arthritis. The delivery of drug via ocular, vaginal, dental, and nose to brain routes for the treatment of diverse local and systemic ailments for instance alopecia, periodontitis, and Parkinson’s are possible. In the cosmetic industries, UV absorber nanoemulgel protected skin from sunburn
