Background: Nowadays cancer is a buzzword in every corner of the world. Back a few decades, cancer was not that much known to the people of South Asia let alone known of Leukemia. Many countries in the South Asian region are designated as developing countries. Hence, the deficiency of diagnosis system, treatment, management, and lack of knowledge about leukemia in this region are major problems. Therefore, the incidence rate, mortality rate, and several deaths are increasing day by day. Methods: This cross-sectional study is aimed to investigate the incidence and mortality of leukemia in South Asian Countries for the year 2020 by acquiring data from the global cancer project (GLOBOCAN2020) accessible at https://***. Results: In South Asia, 1,733,573 cancer cases were documented in 2020 where 62,163 cases were leukemia related. The highest incidence rate was reported in Pakistan (4.3 in 1,000,000) and Sri Lanka (4.1 in 1,000,000) and the lowest in Bangladesh (1.8 in 1,000,000) and Nepal (2.0 in 1,000,000). On the other hand, 1,124,875 death had been reported in 2020, where 45,707 (4.1%) death was associated with leukemia. Pakistan (3.4 in 1,000,000) and Maldives (3.1 in 1,000,000) had the highest death and lowest in Bangladesh (1.4 in 1,000,000) and Nepal (1.5 in 1,000,000). Adults aged from 60 - 85 years old have the highest rate of incidence and mortality rate in all countries except Nepal. Conclusions: Leukemia is one of the major concerning cancer of all ages people in South Asia, the situation and related risk factors information can be helpful to reduce death through proper treatment.

Isolation and Characterization of Beneficial Microorganisms in Organic, Semi-Organic and Conventional Fertilizer Treated Agricultural Field Soil and Comparison of Bacterial Richness

引用

Journal of Agricultural Chemistry and Environment 2020年第4期9卷 223-239页

作者： md. Mahfujur Rahman Laisa Ahmed Lisa Sunzid Ahmed md. Nazim Uddin Tuhina hasan Sharmin Zaman Department of Microbiology Jagannath University Dhaka Bangladesh Department of Biochemistry and Molecular Biology Jagannath University Dhaka Bangladesh Centre for Advanced Research in Sciences (CARS) University of Dhaka Dhaka Bangladesh Horticulture Research Center Bangladesh Agriculture Research Institute (BARI) Gazipur Bangladesh

The effect of different farming systems on microbial communities in agricultural environment was investigated in the present study. Depending on the present farming trend, the microbial distribution in agricultural soils treated with organic, semi-organic and conventional fertilizers was analyzed. A total of 20 soil samples were collected from different types of agricultural fields of Bangladesh Agricultural Research Institute (BARI, Gazipur). Microorganisms playing beneficial roles in soil such as nitrogen fixation (e.g. Rhizobium sp., Azotobacter sp.), phosphate solubilization (e.g. Bacillus sp., Pseudomonas sp., Phosphobacteria) and auxin production (e.g. Pseudomonas sp., Serratia sp. and Bacillus sp.) were evaluated from each of the samples. The results revealed that agricultural fields treated with chemical fertilizers showed lower microbial count than that of organic fertilizer treated agricultural fields’ soil samples. In addition, organic fertilizers amended field soils have higher phytohormone (Auxin) activities, phosphate solubilization bacteria and other bacterial richness compared to chemical fertilizer applied field soil.

Background: As the half-life of intact parathyroid hormone (iPTH) is very low, it reflects parathyroid insufficiency within minutes to hours after total thyroidectomy. Therefore, iPTH level assessment in the postoperative period can be used to predict the development of hypocalcaemia. The optimal time point to measure serum iPTH is important for the accurate prediction of hypocalcaemia. Aim: This paper aims to evaluate the ability of iPTH as an early predictive marker of hypocalcaemia and determine which time iPTH is more able to predict postoperative hypocalcaemia. Method: This prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, BSMMU, Dhaka, from July 2020 to December 2021, with 67 patients who underwent total thyroidectomy. iPTH levels were measured on the day before the operation and at 1 hour, 4 hours, and 24 hours after the operation. *** levels were measured on the day before the operation and 1st postoperative day. All the data were compiled and sorted properly and were analyzed statistically. Results: Postoperative hypocalcaemia developed in 18 cases, with an incidence of 26.9%. Pearson correlation showed a significant correlation between postoperative iPTH at 1 hr, 4 h, and 24 hr with 1st postoperative calcium value. The Receiver operating characteristic (ROC) curve was processed for the postoperative iPTH at 1 hr, 4 h, and 24 hr. The sensitivity, specificity, cut-off value, and mean AUC found 93.9%, 94.4%, ≤14.0, 0.988;95.9%, 94.4%, ≤09.5, 0.993 and 91.8%, 94.4%, ≤11.0, 0.993 respectively. Conclusion: iPTH can be used as an early predictor of post-thy-roidectomy hypocalcaemia. 4 hr iPTH showed more sensitivity and specificity for a cut-off value near the laboratory reference range.

A novel benzene core photonic crystal fiber （BC-PCF） is proposed for plasma sensing applications. The proposed BC-PCF parameters have been tuned to gain high sensitivity, high numerical aperture （NA）, and low confinement loss, and modality over the extensive variety of 0.7 μm to 1.9μm wavelength. The explored results for the ideal structure have exhibited the high sensitivity up to 77.84% and negligible confinement loss of 7.9×10^-3dB/m at 1.3μm wavelength. The V-barometer remains under 2.405 over the whole working wavelength. So the proposed BC-PCF is a single mode fiber, which advances the long partition correspondence applications. Furthermore, high numerical aperture （NA） makes the fiber potential candidate in medical imaging applications. The plan of the sensor is to find out the creative potential outcomes in sensing applications.

Cloud point （CP） determinations of 4-（1,1,3,3-tetramethylbutyl）phenyl-polyethylene glycol （TX-100 （nonionic surfactant）） was carried out in aqueous as well as in the attendance of drug （ceftriaxone sodium trihydrate （CFT））/（CFT ＋ different inorganic salts） and discussed thoroughly. Nonionic surfactants are employed exten- sively in different formulations. In aqueous solution, the values of CP of TX-100 are obtained to increase by means of enhancing of their concentration in the solution. The CP values of TX-100 solutions were found to de- crease in the presence of drug and their values decrease more with rising concentrations of the drug. The values of CP of CFT and TX-100 mixtures were found to further decrease in the attendance of inorganic salts in compar- ison to their absence. The effect of different sodium salts in decreasing CP values of TX-100 was achieved in the following order： NaCO3 〉 Na2SO4 〉 NaCl. However, in the case of potassium and ammonium salts, the decreasing order obtained is K2SO4 〉 KCO3 〉 KCI and （NH4）2SO4 〉 Na2CO3 〉 NH4Cl respectively. Various thermodynamic pa- rameters for example standard free energy （△G c）, standard enthalpy （△H c） as well as standard entropy （△S c） changes of phase separation were also evaluated and discussed in detail on the basis of their behavior.
