But due to fruit fly and borer the important cash crop is prone to attacks of insect pests and diseases its developmental stages. The study has been conducted to find out the effect of pre-harvest fruit bagging against fruit fly and borer on post-harvest quality and shelf life of mango cv. Amrapali. Under this study five different bagging materials were used e.g (i) control (non-bag fruit), (ii) brown paper bag (T1), (iii) white paper bag (T2), (iv) black polythene bag (T3) and (v) white polythene bag (T4). In this case non-bagging fruits were considered as control (T0). The experiment was laid out in randomized complete block design with three replications. Significant variations among the pre-harvest bagging materials in relation to physio-chemical quality attributes and shelf life of mango cv. Amrapali was found. The attributes such as weight, length and breadth of fruit, skin color, moisture content, dry matter content, Vitamin-C, sugar content (reducing, non-reducing and total sugar), total soluble solids content and shelf life were significantly influenced by the bagging materials. All parameters except Vitamin-C of the bagged fruits were higher than that of control fruits. Highly significant difference in respect of shelf life between bagged and non-bagged fruit was observed. The longer shelf life (15.06 days) was observed in brown paper bag whereas the shortest shelf life (7.92 days) was in control fruits. It was observed that all bagging materials were 100% effective against fruit fly and borer attack but all physical and chemical parameters were significantly affected due to apply different bagging materials. Considering all parameters, it was found that brown paper and white paper bagged fruits mangoes appeared to be the best in respect of skin color weight and size of fruit, moisture content, dry matter content, Vitamin-C content, total soluble solids content, and extending shelf life in mango cv. Amrapali.\u0000J.

The current research attempts to identify the phytochemicals, cytotoxicity effects, and antioxidant activities of the stem of A. tricolor, A. blitum, A. viridis, and A. spinosus. The stem powder was extracted by solvent using methanol, ethanol, and aqueous. The methods were used for phytochemical screening (standard protocol), total phenol content (Folin-ciocalteau assay), total flavonoid content (aluminum colorimetric assay), cytotoxicity (brine shrimp lethality assay) and antioxidants (phosphomolybdate and DPPH assay). The phytochemical analysis revealed the existence of alkaloids, flavonoids, terpenoids, carbohydrate, glycosides, c. glycosides, amino acids, xanthoproteins, phenols, saponins, steroids, and coumarins. Among the four species, the methanolic extracts of A. blitum showed maximum quantities of phenol (20.02 ± 0.32 mg GAE/g), flavonoid (27.76 ± 0.29 mg QE/g) and high antioxidant activity (IC50 = 103.25 ± 1.52 µg/ml). The highest total antioxidant capacity was observed in the ethanolic extract of A. viridis (48.53 ± 2.98 mg AA/g). The stem of A. blitum showed little cytotoxic impact (LC50 <1000) and the rest of the species were non-cytotoxic (LC50>1000). The findings demonstrated that the selected Amaranthus spp. are a valuable source of phytochemicals and natural antioxidants. This research suggests conducting further investigation to detect novel compounds.\u0000J.

Solid dispersion of azithromycin represented a formulation with enhanced dissolution and antibacterial activity. The study designed to evaluate the in-vivo potential of azithromycin-loaded solid dispersion in Escherichia coli-induced diarrheagenic (DEC) mice. Diarrhea was induced in Swiss Albino mice by the oral administration of bacterial culture (100 μl of 1010 CFU/ml) in high glucose Dulbecco’s modified Eagle’s medium (DMEM). The E. coli-infected diarrheal mice received oral administration of azithromycin-loaded solid dispersion, equivalent doses of pure azithromycin and/or vehicle (DMEM in high glucose) for 3 days; and their effects on diarrheal score, inflammatory markers, and histology of intestinal tissues were observed. Azithromycin-loaded solid dispersion treatment prevented diarrhea and retardation of growth in infected mice more efficiently than the equivalent doses of pure azithromycin. The E. coli-infected mice demonstrated soft feces with irregular intervals; however, the nature and frequency of feces were improved with azithromycin-loaded solid dispersion. The increased level of total white blood cells and % of neutrophil was also significantly decreased with solid dispersion of azithromycin. In contrast, pure azithromycin did not alter the counts compared to disease control mice. Furthermore, the colonic tissues of E. coli-infected mice showed loss of epithelial integrity with sub-mucosal edema and also associated with increased serum amylase and C-reactive protein levels. However, solid dispersion of azithromycin-treated mice exhibited restoration of colonic tissue structure with a significant attenuation in serum amylase and C-reactive protein levels compared to pure azithromycin and/or vehicle-treated mice. Solid dispersion of azithromycin was more effective against E. coli-infected diarrheagenic mice than the equivalent doses of pure azithromycin; and the effect was dose-dependent.\u0000J.

The study aimed to determine the relationship between bacterial pneumonia and chronic periodontitis. This was a cross sectional type of descriptive study which was carried out among the 104 patients attending at Dental Outpatient Department, Barind Medical College Hospital, Rajshahi for the treatment of chronic periodontitis which were selected purposely. Most responders (46.2%) were between the ages of 21 and 30, and the vast majorities (88.5%) were men. Data showed that 92.0% of people came from a nuclear family, 63.5% had completed high school, and 70.2% had a monthly house hold income of less than 10,000 Taka. Great majority (46.2%) lived in standard housing without windows (52.9%) or ventilation (66.0%). With regards to the evaluation of chronic periodontal condition, 87.5% of those with community acquired pneumonia had history of gum bleeding, compared to 95.2% of those with no history of this. Most cases of pneumonia were identified as being caused by Streptococcus pneumonia (59.80%) after bacteriological testing. One-way analysis of variance revealed a significant correlation (p<0.001) between oral hygiene index, dental calculus index and dental periodontal index and bacterial pneumonia. Bacterial pneumonia was found to be substantially linked with housing condition, ventilation, sunlight and oral hygiene index (p<0.05). People would not get bacterial pneumonia if we told them to take care of their gums and teeth, patients who had received periodontal therapy and practiced good oral hygiene were found to have a risk of pneumonia that was nearly half that of the general population.\u0000J.

A fungal pathogen was isolated using tissue planting methods. The genomic DNA of the isolated fungus was amplified and sequenced under the Sanger Sequencing platform. Blast search showed 99% sequence similarity with Fusarium incarnatum-equiseti species complex. The vegetative growth of the targeted fungus was assessed on several fungal culture media, in which Richard Agar medium exhibited the maximum mycelial growth at 25ºC temperatures. Neutral to slightly alkaline condition was mostly preferred by this fungus. Among three light regimes, the complete light condition was ideal for the mycelial growth of the fungus. Three aqueous plant extracts were evaluated to check in vitro vegetative growth, in which garlic (20%) was quite enough to restrict complete mycelial growth of it. Two food preservatives were also assessed, where sodium benzoate (50 mM) was most effective for the restriction of the targeted fungus compared to vinegar. Therefore, garlic and sodium benzoate could be used to manage the fungal growth of F. incarnatum-equiseti associated with Amla fruits. To the best of our knowledge, Amla fruit rot caused by F. incarnatum-equiseti is the first record in Bangladesh.\u0000J.

A high mitotic index value shows the higher growth patterns of plants than others. The interphase nuclear structure analysis showed differences in the organization and distribution of chromatin within the nuclei of the cultivars. Percentages of heterochromatin were found highest in BARI Sheem-5 and lowest in BARI Sheem-3 which may be considered as more primitive and more advance in nature, respectively. Some cultivars exhibited a more condensed and organized nuclear structure, while others displayed a more dispersed and irregular arrangement of chromatin. Furthermore, the measurement of heterochromatin percentage indicated significant variations among the cultivars. Heterochromatin, which is associated with the gene silencing and genome stability, ranged from low to high percentages in different cultivars. This suggests potential differences in gene expression and genomic stability among the 10 cultivars of L. purpureus. Overall, the study highlights the existence of genetic diversity in L. purpureus cultivars, as evidenced by variations in interphase nuclear structure and heterochromatin percentage. These findings contribute to a better understanding of the genetic and epigenetic factors that influence the phenotypic characteristics agronomic performance of L. purpureus.\u0000J.

Slaughtering of animal results in 75-85% bleeding efficiency whereas dead animals do not bleed at all. Considering these views, this work aimed to develop a protocol for the differentiation of meat from dead and slaughtered animals based on hemoglobin content. Meat samples collected from dead and slaughtered layer, broiler and Sonali chickens and cattle were analyzed with two reagents viz. leucomalachite green (LMG) and tetramethyl benzidine (TMB). In brief, the muscle tissue was chopped, in triplicate, and placed in distilled water to liberate hemoglobin, which was allowed to react with hydrogen peroxide followed by reaction with LMG and TMB reagents for color production. The color output was graded by visual inspection as well as by measuring optical density on a spectrophotometer. The optical density ratios of meat from dead to slaughtered animals were 1.41±0.13, 1.89±0.43, 2.31±0.41, 2.01±34 with LMG and 4.76±1.13, 2.31±0.60, 6.55±0.25, 2.31±1.02 with TMB for white layer, brown layer, broiler and Sonali chickens, respectively. Meat from dead cattle produced blue color whereas that of slaughtered cattle produced green to light blue color. The intensity of color output was proportionate to the amount of hemoglobin content. The two chemicals, LMG and TMB, were equally effective in differentiating meat from dead and slaughtered animals.\u0000J.
