94mTc was produced via natmo(p, xn)94mTc reaction. Deposition of moo3 on Cu substrate was carried out via two special sedimentation methods for the production of 94mTc. The 533 mg of moo3, 600 μL of collodium (nitrocellulose) and 3 mL of acetone were used to prepare a moo3 layer of 11.69 cm2 and 45.81 mg·cm-2. also, a moo3 layer was prepared by 533 mg of moo3, 71.188 mg of methylcellulose and 4 mL of water. The targets were checked by SEm and thermal shock test.

BACKGRoUND one of the main characteristics of oral squamous cell carcinoma(oSCC)is that it metastasizes to cervical lymph nodes frequently with a high degree of local invasiveness.A primary feature of malignant tumors is their penetration of neighboring tissues,such as lymphatic and blood arteries,due to the tumor cells'capacity to break down the extracellular matrix(ECm).matrix metalloproteinases(mmPs)constitute a family of proteolytic enzymes that facilitate tissue remo-deling and the degradation of the ***-9 and mmP-13 belong to the group of extracellular matrix degrading enzymes and their expression has been studied in oSCC because of their specific ***-13,a collagenase family member,is thought to play an essential role in the mmP activation cascade by breaking down the fibrillar collagens,whereas mmP-9 is thought to accelerate the growth of *** mmP-13 expression has been associated with tumor behavior and patient prognosis in a number of malignant *** authors wish to thank Jadhav KB for his valuable opinion during the preparation of the manuscript.

In this study, the biosorption of copper and zinc ions by Chlorella sp. and Chlamydomonas sp. isolated from local environments in malaysia was investigated in a batch system and by microscopic analyses. Under optimal biosorption conditions, the biosorption capacity of Chlorella sp. for copper and zinc ions was 33.4 and 28.5 mg/g, respectively, after 6 hr of biosorption in an immobilised system. Batch experiments showed that the biosorption capacity of algal biomass immobilised in the form of sodium alginate beads was higher than that of the free biomass. Scanning electron microscopy and energy-dispersive X-ray spectroscopy analyses revealed that copper and zinc were mainly sorbed at the cell surface during biosorption. Exposure to 5 mg/L of copper and zinc affected both the chlorophyll content and cell count of the algal cells after the first 12 hr of contact time.

Adult neurogenesis persists after birth in the subventricular zone, with new neurons migrating to the granule cell layer and glomerular 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 remodeling triggered by memory 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. moreover,the continuous integration of new neurons in the olfactory bulb plays a pivotal role in regulating olfactory information processing. This adaptive process responds to changes in epithelial composition and contributes to the formation of olfactory memories by modulating cellular connectivity within the olfactory bulb and interacting intricately with higher-order brain regions. The role of adult neurogenesis in olfactory bulb functions remains a topic of debate. Nevertheless, the functionality of the olfactory bulb is intricately linked to the organization of granule cells around mitral and tufted cells. This organizational pattern significantly impacts output, network behavior, and synaptic plasticity, which are crucial for olfactory perception and memory. Additionally, this organization is further shaped by axon terminals originating from cortical and subcortical regions. Despite the crucial role of olfactory bulb in brain functions and behaviors related to olfaction, these complex and highly interconnected processes have not been comprehensively studied as a whole. Therefore, this manuscript aims to discuss our current understanding and explore how neural plasticity and olfactory neurogenesis contribute to enhancing the adaptability of the olfactory system. These mechanisms are thought to support olfactory learning and memory, potentially through increased
