Background: Cyclophosphamide (Cpd), a common immunosuppressive and chemotherapeutic drug, can cause hepatotoxicity by inducing inflammation and oxidative stress. Dapagliflozin (Dapa) and other sodium-glucose cotransporter-2 inhibitors (SGLT2i) have anti-inflammatory and antioxidant properties, and Silymarin is a natural compound extracted from the seeds of the milk thistle plant (Silybum marianum). It is best known for its antioxidant, anti-inflammatory, and hepatoprotective effects.Objective: By measuring oxidative stress, inflammation, and liver regeneration parameters, with an emphasis on the Nrf2/HO-1 pathway and hepatocyte nuclear factors (HNF4α and HNF6), Dapa's hepatoprotective effects in comparison to Sil on Cpd-induced liver injury will be evaluated. Methods: Five (5) groups of male rats ten rats each were created: control, vehicle (Na-CMC), Cpd (30mg/kg), Cpd + Dapa (3mg/kg), and Cpd + Sil (200mg/kg).. Rat liver tissue was examined for Nrf2, HO-1 (qRT-PCR), HNF4α (ELISA), and HNF6 (Western blot) levels after ten days. Results: Cpd significantly reduced Nrf2, HO-1, HNF4α, and HNF6 levels (*p < 0.0001). Dapa and Sil restored these markers, with Dapa showing superior upregulation of Nrf2 (2.182 ± 0.540 vs. Cpd 0.244 ± 0.096) and HO-1 (2.051 ± 0.533 vs. CP 0.487 ± 0.178) (*p< 0.0001). Dapa also significantly increased HNF4α (2135 ± 297.9 vs. CP 229.5 ± 50.21) and HNF6 (3.635 ± 0.610 vs. CP 0.515 ± 0.255) (*p< 0.001), outperforming Sil in enhancing HNF6 (*p < 0.05). Conclusion: Dapa ameliorates Cpd-induced hepatotoxicity by activating the Nrf2/HO-1 pathway and restoring HNF4α/HNF6 expression, demonstrating comparable or superior efficacy to Sil. These findings highlight Dapa’s potential as an adjunct therapy to mitigate chemotherapy-induced hepatotoxicity
The residual limb within the prosthesis, is often subjected to tensile or fatigue stress with varying temperatures. The fatigue stress and temperatures difference which faced by amputee during his daily activities will produces an environmental media for growth of fungi and bacteria in addition to the damage that occurs in the prosthesis which minimizingthe life of the prosthetic limb and causing disconfirm feeling for the amputee.

... Show MorePredicting vertical stress was indeed useful for controlling geomechanical issues since it allowed for the computation of pore pressure for the formation and the classification of fault regimes. This study provides an in-depth observation of vertical stress prediction utilizing numerous approaches using the Techlog 2015 software. Gardner's method results in incorrect vertical stress values with a problem that this method doesn't start from the surface and instead relies only on sound log data. Whereas the Amoco, Wendt non-acoustic, Traugott, average technique simply needed density log as input and used a straight line as the observed density, this was incorrect for vertical computing stress. The results of these methods
... Show MoreLet G be a graph, each edge e of which is given a weight w(e). The shortest path problem is a path of minimum weight connecting two specified vertices a and b, and from it we have a pre-topology. Furthermore, we study the restriction and separators in pre-topology generated by the shortest path problems. Finally, we study the rate of liaison in pre-topology between two subgraphs. It is formally shown that the new distance measure is a metric
The current research aims to prepare a proposed Programmebased sensory integration theory for remediating some developmental learning disabilities among children, researchers prepared a Programme based on sensory integration through reviewing studies related to the research topic that can be practicedby some active teaching strategies (cooperative learning, peer learning, Role-playing, and educational stories). The Finalformat consists of(39) training sessions.
The reaction oisolated and characterized by elemental analysis (C,H,N) , 1H-NMR, mass spectra and Fourier transform (Ft-IR). The reaction of the (L-AZD) with: [VO(II), Cr(III), Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II)], has been investigated and was isolated as tri nuclear cluster and characterized by: Ft-IR, U. v- Visible, electrical conductivity, magnetic susceptibilities at 25 Co, atomic absorption and molar ratio. Spectroscopic evidence showed that the binding of metal ions were through azide and carbonyl moieties resulting in a six- coordinating metal ions in [Cr (III), Mn (II), Co (II) and Ni (II)]. The Vo (II), Cu (II), Zn (II), Cd (II) and Hg (II) were coordinated through azide group only forming square pyramidal

The question about the existence of correlation between the parameters A and m of the Paris function is re-examined theoretically for brittle material such as alumina ceramic (Al2O3) with different grain size. Investigation about existence of the exponential function which fit a good approximation to the majority of experimental data of crack velocity versus stress intensity factor diagram. The rate theory of crack growth was applied for data of alumina ceramics samples in region I and making use of the values of the exponential function parameters the crack growth rate theory parameters were estimated.

... Show MoreBackground: Male infertility is a global concern and it tends to increase due to miscellaneous factors, such as environmental toxins and genetic and lifestyle choices. The aryl hydrocarbon receptor (AHR) has recently attracted attention due to its involvement in male infertility mechanisms and impact on sperm production and function. AHR, a versatile receptor expressed in various tissues, including the testes, regulates the genes involved in spermatogenesis. AHR activation is associated with cell cycle regulation and chromatin condensation during spermatogenesis. Objectives: This study aimed to investigate the influence of AHR activation on blood-testis barrier (BTB) integrity, focusing on the role of tight junction protein-1 (TJP1)
