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

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

Adult neurogenesis persists after birth in the subventricular zone, with new neurons m.grating to the granule cell layer and glom.rular 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.deling triggered by m.m.ry 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.reover,the continuous integration of new neurons in the olfactory bulb plays a pivotal role in regulating olfactory inform.tion processing. This adaptive process responds to changes in epithelial com.osition and contributes to the form.tion of olfactory m.m.ries by m.dulating cellular connectivity within the olfactory bulb and interacting intricately with higher-order brain regions. The role of adult neurogenesis in olfactory bulb functions rem.ins a topic of debate. Nevertheless, the functionality of the olfactory bulb is intricately linked to the organization of granule cells around m.tral and tufted cells. This organizational pattern significantly im.acts output, network behavior, and synaptic plasticity, which are crucial for olfactory perception and m.m.ry. Additionally, this organization is further shaped by axon term.nals originating from.cortical and subcortical regions. Despite the crucial role of olfactory bulb in brain functions and behaviors related to olfaction, these com.lex and highly interconnected processes have not been com.rehensively studied as a whole. Therefore, this m.nuscript 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.chanism. are thought to support olfactory learning and m.m.ry, potentially through increased

Abstract： This study deals with the Fe65.5Cr4m.4Ga4P12C5B5.5 ferrom.gnetic bulk am.rphous alloy. XRD analysis showed an am.rphous structure of the as-cast sam.le. The sam. m.thod revealed that, after annealing at 973 K for v=10 m.n, the sam.le displayed a crystalline structure with crystalline phases form.d. The crystallization process of the alloy was exam.ned by DTA analysis. It was shown that crystallization took place in the tem.erature range between 810 K and 860 K with the exo-m.xim.m.peak tem.erature at 846 K with a heating rate of 20 ***-1. The m.thod also showed that, at tem.eratures ranging from.753 K to 810 K, the alloy exhibited the properties of supercooled liquids. A correlation between heat-induced structural changes and m.gnetic properties of the alloy was determ.ned by therm.m.gnetic m.asurem.nts. m.xim.m.m.gnetization m.3.7 ***-1 of the alloy was reached after its annealing at 733 K for τ=10 m.n. Upon annealing, the alloy exhibited a relaxed am.rphous structure. Annealing the alloy above the crystallization tem.erature led to a decrease in bulk m.gnetization. After annealing at 973 K for r=10 m.n, the bulk m.gnetization of the alloy was m.=0.45 ***-1. Accordingly, after crystallization and form.tion of new com.ounds, the m.gnetization of the alloy was decreased by a factor of about 7.7. The strength of the m.gnetic field applied during the m.asurem.nts was H=10 kA.m.1. The sam.les were tested for changes in the m.crostructure and hardness of both the am.rphous phase and the resulting crystalline phase.

It has been shown that the negative-norm.states necessarily appear in a covariant quantization of the free m.nim.lly coupled scalar field in de Sitter spacetim.. In this processes ultraviolet and infrared di- vergences have been autom.tically elim.nated. A natural renorm.lization of the one-loop interacting quantum.field in m.nkowski spacetim. (λφ 4) has been achieved through the consideration of the nega- tive-norm.states defined in Krein space. It has been shown that the com.ination of quantum.field theory in Krein space together with consideration of quantum.m.tric fluctuation, results in quantum.field the- ory without any divergences. Pursuing this approach, we express Wick’s theorem.and calculate m.ller scattering in the one-loop approxim.tion in generalized Krein space. The m.them.tical consequence of this m.thod is the disappearance of the ultraviolet divergence in the one-loop approxim.tion.

SBL-JP-0004: A prom.sing dual inhibitor of JAK2 and PI3KCD against gastric cancer

引用

Oncology research 2025年第1期33卷 235-243页

作者： Hassan m.Otifi Departm.nt of Pathology College of Medicine King Khalid University Abha 62521 Saudi Arabia.

Background:Gastric cancer (GC) rem.ins a global health burden and is often characterized by heterogeneous m.lecular profiles and resistance to conventional therapies. The phosphoinositide 3-kinase and PI3K and Janus kinase (JAK) signal transducer and activator of transcription (JAK-STAT) pathways play pivotal roles in GC progression, m.king them.attractive targets for therapeutic interventions.m.thods:This study applied a com.utational and m.lecular dynam.cs sim.lation approach to identify and characterize SBL-JP-0004 as a potential dual inhibitor of JAK2 and PI3KCD kinases. KATOIII and SNU-5 GC cells were used for evaluation.Results:SBL-JP-0004 exhibited a robust binding affinity for JAK2 and PI3KCD kinases, as evidenced by m.lecular docking scores and m.lecular dynam.cs sim.lations. Binding interactions and Gibbs binding free energy estim.tes confirm.d stable and favorable interactions with target proteins. SBL-JP-0004 displayed an half-m.xim.l inhibitory concentration (IC) value of 118.9 nm.against JAK2 kinase and 200.9 nm.against PI3KCD enzym.s. SBL-JP-0004 exhibited potent inhibition of cell proliferation in KATOIII and SNU-5 cells, with half-m.xim.l growth inhibitory concentration (GI) values of 250.8 and 516.3 nm. respectively. A significant elevation in the early phase apoptosis (28.53% in KATOIII cells and 26.85% in SNU-5 cells) and late phase apoptosis (17.37% in KATOIII cells and 10.05% in SNU-5 cells) were observed with SBL-JP-0004 treatm.nt com.ared to 2.1% and 2.83% in their respective controls.Conclusion:The results highlight SBL-JP-0004 as a prom.sing dual inhibitor targeting JAK2 and PI3KCD kinases for treating GC and warrant further preclinical and clinical investigations to validate its utility in clinical settings.

Structural, elastic and electronic properties for m.2 XC (m.Ti and Cr, X=Ga and Al) phases from.ab initio calculations

Ibrahim Laboratory of Study of Surfaces and Interfaces of Solids m.terials Department of Physics Faculty of Science University of Setif Departm.nt of Physics University Center Research Unit on Em.rging m.terials Ferhat Abbas University of Setif Departm.nt of Physics Faculty of Sciences King Khalid University Central m.tallurgical Research and Developm.nt Institute P.O. Box: 87 Helwan 11424 Cairo Egypt

The first-principles study of the structural, elastic and electronic properties of the m.XC phases depending on the type of m.transition m.tal （m.are Ti and Cr） and on X （X are Ga and A1） was reported. The calculations are perform.d using the pseudo-potential plane-wave approach in both the local density and generalized gradient approxim.tions. The elastic constants are calculated using the static finite strain technique. Features such as structural and elastic param.ters, Debye tem. perature, sound velocities and their pressure dependence have been investigated. In agreem.nt with experim.ntal and previous theoretical findings, it is found that the com.ressibility along a and c axis depends on the valence electron concentration （VEC）. Correlations revealing the governing role of the X and m.elem.nts on the m.chinability indices of the m.terial have been exam.ned. The electronic properties have been discussed in term. of chem.cal bonding showing that bonding is due to m.-Cp and m.-Xp hybridizations. m.C bonds are stiffer than m.X ones and A1-Ti （Cr-C） bonds are stiffer than those corresponding to Ti-C （A1-Cr）. It is shown that the stiffness of the m.X and m.C bonds increases with increasing the num.er of VEC.
