A sim..e, rapid, and reproducible m..hod is described em..oying solid phase extraction(SPE) using dichlorom..hane followed by gas chrom..ography(GC) with flam..ionization detection(FID) for determ..ation of volatile organic com..und(VOC) from..he Buriganga River water of Bangladesh. The m..hod was applied to detect the benzene, toluene, ethylbenzene, xylene and cum..e(BTEXC) in the sam..e collected from..he surface or 15 cm..epth of water. Two hundred m..of n hexane pretreated and filtered water sam..es were applied directly to a C 18 SPE colum.. BTEXC were extracted with dichlorom..hane and average concentrations were obtained as 0 104 to 0 372 μg/m.. The highest concentration of benzene was found as 0 372 μg/m..with a relative standard deviation(RSD) of 6 2%, and cum..e was not detected. Factors influencing SPE e.g., adsorbent types, sam..e load volum.. eluting solvent, headspace and tem..ratures, were investigated. A cartridge containing a C 18 adsorbent and using dichlorom..hane gave better perform..ce for extraction of BTEXC from..ater. Average recoveries exceeding 90% could be achieved for cum..e at 4℃ with a 2 7% RSD.

Com..sting is a suitable environm..t-friendly technique to m..ify organic waste to organic fertilizers and works as soil conditioners by regulating different biological processes. The m..n objective of a sustainable agricultural production system..an be achieved by using quality com..st and thereby im..oving soil health and increased crop yield. This desktop research sum..rizes the role of com..sting for sustainable agricultural developm..t with their prospective role, opportunities, and challenges in the context of Bangladesh. Som..attention is also given to the com..sting process and com..st industries in Bangladesh. Benefits and constraints regarding the use of com..st for achieving sustainable agricultural production system..are also discussed.

Neurogenesis dynam..s in the olfactory bulb:deciphering circuitry organization, function, and adaptive plasticity

Neural Regeneration Research 2025年第6期20卷 1565-1581页

作者： m..wiah m..affaa Departm..t of Psychology and Neuroscience Duke UniversityDurhamNCUSA Departm..t of Cell Biology Duke University School of MedicineDurhamNCUSA

Adult neurogenesis persists after birth in the subventricular zone, with new neurons m..rating to the granule cell layer and glom..ular layers of the olfactory bulb, where they integrate into existing circuitry as inhibitory interneurons. The generation of these new neurons in the olfactory bulb supports both structural and functional plasticity, aiding in circuit rem..eling triggered by m..ory and learning processes. However, the presence of these neurons, coupled with the cellular diversity within the olfactory bulb, presents an ongoing challenge in understanding its network organization and function. m..eover,the continuous integration of new neurons in the olfactory bulb plays a pivotal role in regulating olfactory inform..ion processing. This adaptive process responds to changes in epithelial com..sition and contributes to the form..ion of olfactory m..ories by m..ulating cellular connectivity within the olfactory bulb and interacting intricately with higher-order brain regions. The role of adult neurogenesis in olfactory bulb functions rem..ns a topic of debate. Nevertheless, the functionality of the olfactory bulb is intricately linked to the organization of granule cells around m..ral and tufted cells. This organizational pattern significantly im..cts output, network behavior, and synaptic plasticity, which are crucial for olfactory perception and m..ory. Additionally, this organization is further shaped by axon term..als originating from..ortical and subcortical regions. Despite the crucial role of olfactory bulb in brain functions and behaviors related to olfaction, these com..ex and highly interconnected processes have not been com..ehensively studied as a whole. Therefore, this m..uscript aim..to discuss our current understanding and explore how neural plasticity and olfactory neurogenesis contribute to enhancing the adaptability of the olfactory system..These m..hanism..are thought to support olfactory learning and m..ory, potentially through increased
