An Injectable In Situ Forming Collagen/Alginate/Caso4 Composite Hydrogel For Tissue Engineering Applications: Optimization, Characterization And In Vitro Assessments, Samar A. Salim, Samar A. Salim

Nanotechnology Research Centre

In situ injectable hydrogels are effectively employed to fill irregular cavitary bone defects with initiating bone growth in targeted areas. Herein, an injectable composited hydrogel composed of collagen and alginate cross-linked in situ using different concentrations of calcium sulfate (0.15, 0.3 and 0.6%, wt./v) was synthesized. Recently, CaSO4 is frequently supported as a bone graft material for bone regeneration, owing to its biocompatibility and osteoconductive properties. Moreover, hydroxyapatite (Hap) after salinization-step by (3-Aminopropyl) triethoxysilane (APTES) was incorporated for further enhancing the osteoconductive property of injected hydrogels. All fabricated hydrogels were characterized by SEM, FTIR and XRD analyses. While physiochemical characteristics …

Smart Spectrophotometric Approaches For Estimation Of Difluprednate In Existence Of Its Synthetic Precursor And Alkaline Degradation Product; Comparative Statistical Studies And Analytical Ecological Appraisal, Heidi R. Abd El-Hadi, Basma M. Eltanany, Hala E. Zaazaa, Maya S. Eissa

Bulletin of Faculty of Pharmacy Cairo University

Scientists are currently attempting to lessen the harmful effects that chemicals and solvents have on the environment. The current work suggests four sensitive and sustainable spectrophotometric techniques for quantifying difluprednate (DIF) in presence of hydrocortisone acetate, which is a synthetic precursor of DIF, and in the presence of DIF alkaline degradation product. These methods are dual wavelength, fourier self-deconvolution, first derivative, and double divisor derivative ratio. The linearity range for all methods was 15.00-40.00 µg/mL. There is no statistically significant difference between established and reported methods, and the suggested strategies are more environmentally friendly than the reported one.

Near-Neutral Balanced Selection Theory (Nnbst): Implication On The Molecular Evolution Of Sars-Cov-2 And Zika Virus, Nicholas J. Paradis

Graduate Student and Postdoctoral Fellow Symposium

Virus pandemics have significantly impacted human welfare and development. Understanding the true molecular evolution of viruses is critical for preventing future pandemics and developing the next-generation drugs and vaccines. Unfortunately, viruses exhibiting constant genomic substitution rates (GSRs) despite increasing vaccinations and human infections (SARS-CoV-2) and viruses under seemingly extreme conservation (ZIKV) paints a confusing picture of viral evolution, and the main evolutionary theories (Selectionist Theory, Kimura’s Neutral Theory) cannot explain their molecular evolution. Here, we developed a first-principle model, c/u, to characterize reproductive fitness changes in viruses based on variations in the nucleotide/codon mutation rate (c) with respect to the …

Mechanistic Investigation Of C—C Bond Activation Of Phosphaalkynes With Pt(0) Complexes, Roberto M. Escobar, Abdurrahman C. Ateşin, Christian Müller, William D. Jones, Tülay Ateşin

Research Symposium

Carbon–carbon (C–C) bond activation has gained increased attention as a direct method for the synthesis of pharmaceuticals. Due to the thermodynamic stability and kinetic inaccessibility of the C–C bonds, however, activation of C–C bonds by homogeneous transition-metal catalysts under mild homogeneous conditions is still a challenge. Most of the systems in which the activation occurs either have aromatization or relief of ring strain as the primary driving force. The activation of unstrained C–C bonds of phosphaalkynes does not have this advantage. This study employs Density Functional Theory (DFT) calculations to elucidate Pt(0)-mediated C–CP bond activation mechanisms in phosphaalkynes. Investigating the …

Modulation Of Hippocampal Protein Expression By A Brain Penetrant Biologic Tnf-Α Inhibitor In The 3xtg Alzheimer’S Disease Mice, Nataraj Jagadeesan, G. Chuli Roules, Devaraj V. Chandrashekar, Joshua Yang, Sanjana Kolluru, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Background

Biologic TNF-α inhibitors (bTNFIs) can block cerebral TNF-α in Alzheimer’s disease (AD) if these macromolecules can cross the blood–brain barrier (BBB). Thus, a model bTNFI, the extracellular domain of type II TNF-α receptor (TNFR), which can bind to and sequester TNF-α, was fused with a mouse transferrin receptor antibody (TfRMAb) to enable brain delivery via BBB TfR-mediated transcytosis. Previously, we found TfRMAb-TNFR to be protective in a mouse model of amyloidosis (APP/PS1) and tauopathy (PS19), and herein we investigated its effects in mice that combine both amyloidosis and tauopathy (3xTg-AD).

Methods

Eight-month-old female 3xTg-AD mice were injected intraperitoneally with …

Medical Student Research Symposium

Introduction: Urethral stricture treatment has high recurrence rates and adjunct injectable agents have been explored. Amniotic membranes (AM) promote apoptosis of pro-inflammatory cells, prevent differentiation of pro-fibrotic cells, and decrease scar formation. These tissues generated interest in reconstructive urethral surgery. Thus, we performed urethral dilation combined with micronized AM injection in urethral scar tissue for treatment of urethral stricture.

Materials and Methods: Adult males with strictures ≤12Fr in diameter and ≤2 cm in length, International Prostate Symptom Score (IPSS) ≥11 and maximum flowrate <15 ml/s. Reconstituted 100mg micronized AM was injected at the time of urethral dilation. Primary study end point was anatomical success (≥14Fr by cystoscopy) at 6 months. Secondary end points were questionnaires, flow rate, and post void residual. Outcomes assessed at baseline, 5 days, 14 days, 3 months, and 6 months post-injection. Safety was analyzed.

Results: Ten men, mean age of 52 ± 15 years, were included. There were 7 patients with …
