The Chemical Species Of Aluminum Influences Its Paracellular Flux Across And Uptake Into Caco-2 Cells, A Model Of Gastrointestinal Absorption, Yuzhao Zhou, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Aluminum (Al) can cause neurotoxicity, a low-turnover osteomalacia, and microcytic anemia. To test the null hypothesis that the chemical form (species) of Al does not influence its mechanism or rate of absorption from the gastrointestinal tract, Al flux across and uptake into Caco-2 cells was investigated. Caco-2 cells were grown on porous membranes mounted in vertical diffusion chambers or in 35-mm-diameter plastic cell culture dishes. When 8 mM ²⁷Al was introduced as the ion, citrate, maltolate, fluoride, or hydroxide, the apical to basolateral apparent permeability (P_app) of Al correlated highly with the P_app of lucifer yellow …

Manganese Distribution Across The Blood-Brain Barrier. Iv. Evidence For Brain Influx Through Store-Operated Calcium Channels, Janelle S. Crossgrove, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Manganese (Mn) is a required co-factor for many ubiquitous enzymes; however, chronic Mn overexposure can cause manganism, a parkinsonian-like syndrome. Previous studies showed Mn influx into brain is carrier-mediated, though the putative carrier(s) were not established. Studies conducted with cultured bovine brain microvascular endothelial cells (bBMECs), which comprise the blood–brain barrier, revealed ⁵⁴Mn (II) uptake positively correlated with pH, was temperature-dependent, and was sodium- and energy-independent. Brain ⁵⁴Mn uptake correlated inversely with calcium (Ca) concentration, but ⁴⁵Ca uptake was unaltered by high Mn concentration. Lanthanum (La), a non-selective inhibitor of several Ca channel types, as well as …

Oligonucleotide Delivery Systems For Camptothecins, Thomas Burke, Ayhan S. Demir, Ashok J. Chavan, Danzhou Yang

Pharmaceutical Sciences Faculty Patents

Camptothecin drugs are stabilized in their antitumor active lactone form by complexation with an oligonucleotide including RNA or catalytic RNA. The oligonucleotide-camptothecin drug complex may be incorporated within a macromolecular assembly including both viral and non-viral oligonucleotide vectors. The invention allows combination gene and camptothecin drug therapy.

Synthases, Joseph Chappell, Kathleen R. Manna, Joseph P. Noel, Courtney M. Starks

Pharmaceutical Sciences Faculty Patents

Novel synthases and the corresponding nucleic acids encoding such synthases are disclosed herein. Such synthases possess an active site pocket that includes key amino acid residues that are modified to generate desired terpenoid reaction intermediates and products. Synthase modifications are designed based on, e.g., the three-dimensional coordinates of tobacco 5-epi-aristolochene synthase. with or without a substrate bound in the active site.

26Al-Containing Acidic And Basic Sodium Aluminum Phosphate Preparation And Use In Studies Of Oral Aluminum Bioavailability From Foods Utilizing 26Al As An Aluminum Tracer, Robert A. Yokel, Aaron A. Urbas, Robert A. Lodder, John P. Selegue, Rebecca L. Florence

Pharmaceutical Sciences Faculty Publications

We synthesized ²⁶Al-containing acidic and basic (alkaline) sodium aluminum phosphates (SALPs) which are FDA-approved leavening and emulsifying agents, respectively, and used them to determine the oral bioavailability of aluminum incorporated in selected foods. We selected applicable methods from published syntheses (patents) and scaled them down (∼3000- and 850-fold) to prepare ∼300–400 mg of each SALP. The ²⁶Al was incorporated at the beginning of the syntheses to maximize ²⁶Al and ²⁷Al equilibration and incorporate the ²⁶Al in the naturally-occurring Al-containing chemical species of the products. Near infrared spectroscopy (NIR) and X-ray powder diffraction (XRD) were used …

Aluminium Content Of Some Foods And Food Products In The Usa, With Aluminium Food Additives, Salim M. Saiyed, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

The primary objective was to determine the aluminium (Al) content of selected foods and food products in the USA which contain Al as an approved food additive. Intake of Al from the labeled serving size of each food product was calculated. The samples were acid or base digested and analysed for Al using electrothermal atomic absorption spectrometry. Quality control (QC) samples, with matrices matching the samples, were generated and used to verify the Al determinations. Food product Al content ranged from < 1–27,000 mg kg⁻¹. Cheese in a serving of frozen pizzas had up to 14 mg of Al, from basic sodium …

Nanoscintillation Systems For Aqueous-Based Liquid Scintillation Counting, Russell J. Mumper, Michael Jay

Pharmaceutical Sciences Faculty Patents

The present invention relates to the use of nanoscintillation systems, or nanoparticles containing fluor molecules, that can be used to detect an electron-emitting or alpha-particle-emitting radioisotope in the absence of organic-solvents commonly used in organic-based liquid scintillation cocktails. The invention also relates to compositions and use of three oil-in-water microemulsion precursors that can be engineered rapidly, reproducibly, and cost-effectively to produce useful nanoparticles less than 100 nanometers.
