oxidative stress
Opis:: Inflammation is a non-specific immune response to infection, irritation or other injury, the key features being redness, warmth, swelling and pain. A number of mediators are released which alter the resistance of mucosa to injury induced by noxious substances. Oxidative stress is a unifying mechanism of injury in many types of disease processes, including gastrointestinal diseases. It has been defined as an imbalance in the activity of pro and antioxidants. Pro-oxidants favour free radical formation while antioxidants inhibit or retard the same. A number of markers of oxidative stress have been identified. This review provides an overview of various mediators of inflammation and oxidative stress, and diverse approaches for prevention and treatment of gastrointestinal inflammation.

Opis:: Road transportation does an excellent job of connecting Savar's inner and outer areas, but it might be difficult for commuters to decide which mode of transportation to employ because residents of Savar come from a wide range of socioeconomic backgrounds. It is necessary to do in-depth research on the characteristics of people in the study region who choose different modes of transportation to achieve the goal of selecting a certain mode for their travel. Where a person lives can have a significant impact on their typical patterns of travel behavior. People who live closer to the center of things have access to a wider variety of amenities than those who live further away, and as a consequence, their travel patterns are distinct from one another. The study's findings indicate that several factors, including income, age, gender, and vocational qualities and goals, influence a commuter's preferred method of transportation. When it comes to selecting a mode of transportation, the most predictable factors to take into account are trip time and cost. After conducting research, it was found that most excursions are made from this place to Motijheel, Tejgaon, and Savar Export Processing Zone for their services, businesses, and jobs, respectively.

Opis:: Bangladesh, a country that lies on the north shores of the Bay of Bengal, has been blessed with a plethora of natural resources. St. Martin’s Island, the only coral-bearing island in Bangladesh, is undoubtedly regarded as one of the most prized possessions. It is rich in biodiversity, but truly scientific information on it is lacking. In the present investigation, 14 stations adjacent to St. Martin’s Island within the Bay of Bengal were sampled for determining the composition, spatial distribution, species richness, and diversity of pelagic zooplankton. Samples were collected in the pre-monsoon hot season. From the community of zooplankton, 34 species were reported. Most of the species belonged to copepods. Besides, Polychaeta and Cirripedia were also present in the community. The most significant species belonged to Oithona, Canthocalanus, Balanus, Euterpina, and Microsetella. Total zooplankton standing crop varied from 45,000–125,000 ind/m3 and the highest number of species (8) were observed at station 7. Strong variability in the distribution of species was observed in the studied stations. The number of genera collected at each station varied from 4–8. Data on species richness (Df) varied from 1.30–3.04 and that of the Shannon-Wiener Index (H) from 1.33–1.93. The species composition of zooplankton and the species richness and the diversity index of the population was comparable to the other studies carried out in the Central and Western Bay of Bengal.

Opis:: The river system of the Bengal delta encompasses a huge amount of fluvial sand; however, no comprehensive studies were available on using this river sand in foundry industries. Hence, the present research evaluates the foundry properties of trans-boundary Brahmaputra River sand and its prospects for use in foundries. Several laboratory analyses have been performed to elicit the foundry properties using standard methods of foundry analysis, including XRD, XRF, TG-DSC, and FESEM. From the study, the sand contains mainly quartz with small amounts of feldspar, amphibole, chlorite, and mica, and exhibits a subangular to subrounded shape. The sand is dominated by SiO2 (67.81-69.97%) and lesser amounts of other oxides, and it is thermally stable within 1000 °C temperature. The grain fineness number (64-79), mineralogical, chemical, thermal, and foundry properties are suitable for non-ferrous metal casting without distortion. Further, the aluminum and zinc alloy casting with trials demonstrate their potential for use in the foundry industries. The outcomes of this study thus offer valuable information about utilizing Brahmaputra River sand for foundry applications.

Opis:: A field experiment was carried out with two varieties of rice (BR 11 and BRRI dhan 31) during Transplanted Aman season of 2018 in K. bearing deep grey terrace soil of Madhupur tract (AEZ 28) under Bangladesh Rice Research Institute (BRRI), Joydebpur. Gazipur. The objective of the study was to know the effect of NPKSZn on the growth and yield of BR 11 and BRRI dhan 31. There were ten treatment combinations with three replications. The treatments were complete (+NPKSZn), reverse complete (-NPKSZn), +N (+PKSZn), -N (+PKSZn), +P (+NKSZn), -P (+NKSZn), +K (+NPSZn) and -K (+NPSZn). The parameters under study were dry matter production, contents and uptake of N, P, K, S and Zn at active and maximum tillering stages, panicle number m’ and grain yield in both the varieties. All the parameters were positively influenced by the treatments under study. Growth and yield of both the varieties were largely affected by the missing nutrient treatment. The highest performance was found with the complete and reverse control treatments whereas the lowest was found with missing element treatments and of course, with control. BR 11 was found to be a better variety than BRRI dhan 31 in respect of yield and yield contributing characters under the treatments. It was also observed that recently fertilized reverse control plot behaved statistically the same as the long term fertilized complete treatment plot. Yield of rice was positively related to K uptake in both the varieties.

Opis:: Shoreline changes and groundwater quality monitoring have become pressing issues for the coastal region of Bangladesh. This study investigated the shoreline changes from 2000 to 2020 and evaluated the groundwater quality, as well as SWI in the Kuakata coastal area. While analyzing satellite images, the temporal shoreline changes were assessed through the Digital Shoreline Analysis System (DSAS) in ArcGIS 10.4.1. Higher erosion rates (>2 m/year) were found in the southernmost part and the SE part of the studied area. Twenty-five groundwater samples were collected, and the physicochemical parameters were measured to assess the groundwater quality. The geographic information system (GIS) was used to assess the spatial variation of the EC, pH, and Cl⁻ contents through the inverse distance weighted (IDW) interpolation method. The EC, Cl⁻, and pH values of the studied groundwater ranged from (1.2 mS/cm to 19.5 mS/cm), (79.88 mg/L to 11241.67 mg/L), and (7.9 to 8.7), repectively. The analysis revealed that the majority of the groundwater samples were unsuitable for drinking purpose due to higher EC and Cl⁻ values. Saline water intrusion (SWI) was determined by using the alternative EC vs Cl⁻ method in the southern part of the Kuakata beach area, which was closest to the sea.
