Background: Since 2019, the pandemic of Coronavirus disease 2019 (COVID-19) has spread very rapidly in China and Worldwide. COVID-19 is a highly contagious, infectious and rapidly spreading viral disease with an alarming case fatality rate up to 5%. Case Report: In this article, we report a case of 60 years old non diabetic, hypertensive woman infected with COVID-19 who has end stage renal disease (ESRD) on hemodialysis for last 18 months. COVID-19 patients with ESRD need isolation dialysis but most of them cannot be handled properly due to limited hemodialysis machine. With these unavailability and risk, we continue the treatment along with hemodialysis for controlling uraemia and fluid balance. With all effort this patient ended with an uneventful course with clinical improvement, improvement of all laboratory parameters and resolution of radiological findings but follow up RT-PCR cannot done due to changing guideline of discharge criteria of COVID-19 patient in Bangladesh.

Background: Novel corona virus (SARS-Coronavirus-2 SARS-CoV-2) which emerged in China has spread to multiple countries rapidly. Little information is known about delayed viral clearance in mild to moderate COVID-19 pa-tients. As it is highly contagious, health care workers including physicians are high risk of being infected in hospital care. Case Report: A 37 years old Bangladeshi physician working in a paediatric unit of a medical college hos-pital with multiple co-morbidities, hypertension, diagnosed axial spondy-loarthropathy (ankylosing spondylitis) taking disease modifying anti rheu-matic drugs— DMARDs (Salfasalazine) from 2016 till now, chronic persis-tent bronchial asthma on medication developed sore throat, increasing breathlessness and cough admitted to his own hospital on 22 April, 2020. He had a history of contact with a relapse nephrotic syndrome (glomerulone-phritis) patient admitted with severe respiratory distress later confirmed as COVID-19 following RT PCR test on 14 April, 2020. After 3 days of contact with the patient, the physician also developed the symptoms mentioned above. The RT PCR test result of the physician came positive on 18 April, 2020. The physician primarily taken only azithromycin 500 mg once daily along with other regular drugs. On 5, 12 and 18 May, 2020, his sample was taken for re-test and came positive subsequently. After that he started Iver-mectin (0.15 mg/kg) once daily for 3 days and doxycycline 100 mg BD for 7 days. He gave samples again on 27 and 29 May, 2020 which were came nega-tive after 39 days. On full recovery he was discharged from hospital on day 40. We choose the patient because presence of co-morbidities may be asso-ciated with delayed viral clearance and physicians with co-morbidities working in a hospital have high risk of being infected.

Background: By the dawn of this modern era of science, the prime challenge of physician is cardiovascular disease (CVD). The most important modifiable risk factors of CVDs are unhealthy diet, physical inactivity and tobacco use. The effects of unhealthy diet and physical inactivity include abnormal blood lipid, obesity and hypertension. We tried to evaluate and correlate the pattern of lipid profile in obese and non-obese hypertensive patients. Objectives: This study was conducted at medicine department of Cumilla Medical College Hospital. The principal aim was to evaluate the lipid profile in obese and non-obese adult hypertensive patients. Methodology: During this cross sectional analytical study, a total of 100 adult hypertensive patients were taken by purposive sampling. Among them 50 (group 1) patients were taken those were obese and 50 (group 2) patients taken those were non-obese according to BMI measurement on operational definition. Diagnosis of hypertension would be established with the help of ambulatory BP measurements two occasions few minutes apart. The staging of hypertension was done according to JNC7 Criteria. Morning blood samples were taken after 8 - 12 hours of fasting and lipid profiles were done on authentic laboratories. The laboratory values were interpreted according to the operational definition of dyslipidaemia. The ethical research and review committee approved the study protocol and signed informed consent was obtained from the participants. The statistics was analyzed using the IBM SPSS software of version 19.0. Statistical significance was set at p Results: Among the two groups, there were 56 (56%) males and 44 (44%) females. The mean age of group 1 (46.10 ± 11.09) was compared to that of group 2 (

Organo-halide perovskites in planar heterojunction architecture have shown considerable promise as efficient light harvesters in solar cells. We carry out a numerical modeling of a planar lead based perovskite solar cell(PSC) with Cu2ZnSnS4(CZTS) as the hole transporting material(HTM) using the one-dimensional solar cell capacitance simulator(SCAPS-1 D). The effects of numerous parameters such as defect density, thickness, and doping density of the absorber layer on the device performance are investigated. The doping densities and electron affinities of the electron transporting material(ETM) and the HTM are also varied to optimize the PSC performance. It has been observed that a thinner absorber layer of220 nm with a defect density of 1014 cm-3 compared to the reference structure improves the device performance. When doping density of the absorber layer increases beyond 2×1016 cm-3, the power conversion efficiency(PCE) reduces due to enhanced recombination rate. The defect density at the absorber/ETM interface reduces the PCE as well. Considering a series resistance of 5 ?·cm2 and all the optimum parameters of absorber, ETM and HTM layers simultaneously, the overall PCE of the device increases significantly. In comparison with the reference structure, the PCE of the optimized device has been increased from 12.76% to 22.7%, and hence the optimized CZTS based PSC is highly efficient.

Fischer-Tropsch Synthesis(FTS) is an important catalytic chemical reaction that converts a mixture of CO and H2(syngas) derived from biomass, coal or natural gas into ultra-clean fuels or value-added chemicals. However, most traditional catalysts used in the Fischer-Tropsch process are faced with the problems of high deactivation rate triggered by sintering, phase changes and oxidation which hamper their catalytic performance. Metal-organic frameworks(MOFs)-derived materials have been a promising alternative in addressing the catalyst deactivation problems in FTS because of the encapsulation of their metal nanoparticles in carbon matrix and absence of large particle size, among other reasons. Therefore, this review emphasizes the most recent research headway in the investigation of MOFs as precursors to achieve high-performance FTS catalysts. Precisely, the design of iron and cobalt-based FTS catalysts from parent MOFs via MOF-mediated synthesis, the catalytic activity of the MOF-derived materials and the promoter effects under FTS operation were outlined and discussed. We have also evaluated the influence of MOF structures on the FTS performance and compared them with traditional/commercially available catalysts to show the importance of this approach. Finally, the challenges and opportunities to further expedite the extensive research efforts and promote their applications in material design and FT technology were mentioned.
