Development of Rice Bran Functional Food and Evaluation of Its Healthful Properties

Abstract: Rice bran is used as a good source of proteins, oils, crude fibers, carbohydrates, energy, phenolic compounds, γ-oryzanols, and fatty acids (saturated fatty acids 16.59%–21%; monounsaturated fatty acids, 39.82%–49.95%; and polyunsaturated fatty acids, 33.23%–38.57%). Fermented rice bran (FRB) can be prepared by dual fermentation using fungi and lactic acid bacteria for improvement of its functional properties. FRB significantly reduced blood pressure elevation by inhibition of serum angiotensin-converting enzyme (ACE) activity and improved glucose impairment and insulin sensitivity, as well as leptin impairment and serum adiponectin level. FRB improved multifactorial metabolic disorder by the regulation of transcription factors and related gene expression to maintain glucose homeostasis. The anticolitis effect of FRB showed that FRB attenuated intestinal inflammation owing to elevated short-chain fatty acids (SCFAs) and tryptamine production, which might regulate tight junction barrier integrity and intestinal homeostasis. These results suggested that FRB could comprise an effective potential functional food agent for multifactorial metabolic disorder and inflammation.

Detailed Balance Efficiency of Single Junction Perovskite Solar Cell

Abstract: Organometal lead trihalide perovskite materials have attracted the PV researchers tremendously due to some of its promising features such as high absorption coefficient, long carrier diffusion length, low cost synthesis methods and high power conversion efficiency. We have investigated optimal efficiency computationally for methylammonium lead trihalide (MAPbX 3 , X = I, Br, Cl). By using density functional theory (DFT) we have calculated the band structures and density of states (DOS) of these halide perovskites. The detailed balance model is simulated here to obtain theoretical maximum efficiency of perovskite solar cell assuming blackbody as well as the AM 1.5 solar spectra. We have evaluated the power conversion efficiency (PCE) depending on different solar concentration for single junction perovskite solar cells. For the solar spectrum of AM 1.5, the maximum resulting efficiencies of MAPbI 3 , MAPbBr 3 and MAPbCl 3 are 34.95%, 21.25% and 7.39% respectively with full concentration.

Integrated Performance of Fenton Process and Filtration (Activated Charcoal and Sand) for Textile Wastewater Treatment

Abstract: Textile effluents contain complex characteristics with different physicochemical parameters and colorful dye. It is difficult to remove all types of pollutant using a specific treatment process. In this study adsorption filtration alone then Fenton process with sand-gravel mixed filtration and activated charcoal filtration was applied. Fenton process is very effective process for Chemical Oxygen Demand (COD) and Dissolve Organic Carbon (DOC) removal. And Activated carbon is a suitable adsorbent for dye removal. Physicochemical parameters like, COD, DOC, Total Dissolve Solid (TDS), Dissolve Oxygen (DO), Electric conductivity (EC), and pH was measured before and after the treatment process. After filtration by adsorbent filter all the parameter reduced than raw effluent Original Research Article Hossain et al.; CJAST, 39(28): 21-31, 2020; Article no.CJAST.60827 22 but when Fenton process with sand filtration and activated charcoal filtration was applied all the parameter drastically changed than before. DO level was increased after only adsorption filtration process, Fenton and normal sand filtration process, Fenton, and adsorbent filtration process as 1.8 mg/l< 5 mg/l < 6.19 mg/l < 6 mg/l, respectively. Maximum level of EC (61.33%), TDS (82.75%), BOD (92%), COD (80%), DOC (97.57%), and color (78.57%) was decrease after using Fenton process with Activated carbon filtration process than other treatment process, which was within Bangladesh standard value. This result represents the advantage of using Fenton process with adsorption filtration to treat textile effluent. Moreover, this process is easily operating, practical and environment friendly for using in industrial scale.

Antioxidant and antidiarrheal activity of the methanolic extract of Microcos Paniculata roots

Abstract: Microcos paniculata is traditionally used for treating diarrhea, hepatitis, wounds, colds, fever, dyspepsia and heat stroke. Objective. To investigate the antioxidant and antidiarrheal activity of the methanolic extract of M. paniculata roots (RME). Antioxidant and antidiarrheal activity of RME were evaluated by different tests such as total antioxidant capacity (TAC), DPPH free radical scavenging assay (DPPHFRSA), nitric oxide scavenging capacity assay (NOSCA), lipid peroxidation by thiobarbituric acid assay (LPTAA), reducing capacity assessment (RCA), cupric reducing antioxidant capacity (CRAC), castor oil and MgSO4 induced diarrheal tests. The total phenols and flavonoids contents and TAC were 182.78 ± 0.12 mg/g RME (in gallic acid equivalent) and 43.5 ± 0.32 mg/g RME (in quercetin equivalent) and 40.83 ± 0.69 mg/g RME (in ascorbic acid equivalent) respectively. The IC50 values of the RME in DPPHFRSA, NOSCA and LPTAA were 158.47 ± 2.66 μg/mL, 157.91 ± 4.56 μg/mL and 148.29 ± 6.48 μg/mL correspondingly. Concentration dependent reducing power was observed in RCA and CRAC respectively. Moreover, RME 400 mg/kg produced 68.10±16.99 % and 55.83±21.95 % inhibition of diarrhea in antidiarrheal models. Study results indicate that M. paniculata may provide a source of plant compounds with antioxidant and antidiarrheal activity.

Dyslipidemia in diabetes patient is responsible for developing nephritic syndrome with increasing ages, a survey based cross sectional study.

Abstract: Objectives: The objective of this study was to evaluate the level of lipid profile and serum creatinine in patients with diabetes mellitus to correlate the lipid profile abnormalities with serum creatinine levels in diabetic patients. Methods: This cross sectional health survey was carried out with a self-designed standard questionnaire by manual data collection over a six months period (12.09.2015 to 10.04.2016) at three adjacent cities Jessore Sadar, Jhikargacha and Chowgacha upazila respectively. The data were collected from the patients prescription, diagnostic reports and by directly interviewing the patients who were treated as either type 1 or type 2 diabetic 235 fasting patients during the study period. Descriptive statistics were applied to the collected data and analyzed using Microsoft Excel software. Results: In our current survey, the average levels of HDL, LDL, TC, TG and Serum creatinine of investigated patients were observed with respect to their individual groups as for Group A - 40 mg/dl, 110 mg/dl, 220 mg/dl, 135 mg/dl and 0.8 mg/dl; Group B - 40 mg/dl, 150 mg/dl, 320 mg/dl, 290 mg/dl and 1.1 mg/dl; Group C - 38 mg/dl, 180 mg/dl, 210 mg/dl, 388 mg/dl and 1.25 mg/dl; Group D - 32 mg/dl, 190 mg/dl, 240 mg/dl, 435 mg/dl and 1.00 mg/dl. 39.13% male and 35.29% female patients with type 1 DM, whereas 85.25% male and 82.19% female patients with type 2 DM, containing dyslipidemia was seen. Being prone to develop dyslipidemia, the patients with uncontrolled lipid profile abnormalities are among the highest risk to develop diabetic nephropathy characterized by elevated levels of serum creatinine followed by reduced glomerular filtration rate (GFR). Conclusion: This study revealed the interesting outcome is like that, diabetes mellitus patients are more prone to increasing bad cholesterol and creatinine levels in serum and these levels are found to increase with their age as well. Since lipid profile abnormalities, mainly dyslipidemia is inextricably linked with increased serum creatinine level as well as developing diabetic nephropathy, especial attention should be given for controlling hyperglycemia owing to avoid associated cardiovascular complications.
