A Snapshot Investigation Into The Availability And Access To Codeine-Containing Medications Amongst The Irish Population., Katie O'Brien, Pádraig Mckeown, Joseph Phelan

International Undergraduate Journal of Health Sciences

Codeine phosphate is a mild to moderate analgesic and has a weak cough suppressant activity that is available to purchase as an over the counter (OTC) painkiller in Ireland as a compound product. In recent years, countries such as Australia have introduced laws that prohibit the sale of the drug without a valid prescription. This move by Australia begs the question as to why this legislation was introduced and should Ireland follow suit.

The primary aims of the study were to determine knowledge among the general public of codeine-containing medications and their usage levels. The survey also investigated whether current …

Preparation Of Meta-Nitrobenzoylhydrazone Ferrocenoylacetone And Synthesis On Its Basis, Zilola Abduraxmonovna Sulaymonova, Bako Bafayevich Umarov Doctor Chemical Science, Professor

Chemical Technology, Control and Management

β-diketone-ferrocenoylacetone was obtained by Claisen condensation. Meta-nitrobenzoylhydrazone of ferrocenoylacetone (H₂L) was synthesized by the interaction of meta-nitrobenzoic acid hydrazide with ferrocenoylacetone. On its basis, complexes with copper(II) and nickel(II) ions were synthesized. The obtained compounds were characterized by the methods of elemental analysis, IR-, ¹H NMR andelectronic spectroscopy. The research results showed that H₂L in solution exists in the form of a tautomeric mixture: hydrazone, α-hydroxyazine, and cyclic 5-hydroxypyrazoline forms. According to the results of IR and ¹H NMR spectra, the complexes were assigned a planar-square structure, and in them the doubly deprotonated …

Investigating Factors That Affect Hiv-1 Capsid Stability, Max Mao, Joshua Temple

I am interested in elucidating the factors that influence stability of the capsid shell and capturing the structural interactions between HIV capsid, host restriction factors, and small molecules using biochemical and structural biology techniques. HIV capsid shell was broken down and purified into hexamer and pentamer units for in vitro study. Structural assays were performed using X-ray crystallography and biochemical analysis was performed using pelleting assays. By understanding capsid structure with factors that confer stability, …

Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar

Journal of Wellness

The essential question of the relationship between consciousness and matter is ignored in medical school curricula, leading to a machine-like view of the human being that contributes to physician burnout and intellectual dissatisfaction. The evidence suggesting that the brain may not be the seat of consciousness is generally ignored to preserve the worldview of the primacy of matter. By investigating new frameworks detailing the nature of consciousness at different levels of hierarchy, we can bring intellectual rigor to a once opaque subject that supports a fundamental reality about our experience: We are human beings, not only human bodies.

Isolation And Characterization Of Ethyl Acetate Fraction From Abroma Augusta L As An Anti-Inflammatory Agent, Madyawati Latief, Indra Lasmana Tarigan, Muhaimin Muhaimin, Hilda Amanda, Nike Desvi Yulianti

Makara Journal of Science

Abroma augusta is a bush plant that lives on the edge of the river. This plant is commonly used as an anti-inflammatory drug for joints and broken bones. It contains several secondary metabolites, such as alkaloids, triterpenoids, steroids, and flavonoids, which exhibit anti-inflammatory activity. UV-visible (UV-Vis) spectrophotometry of isolate 1.3 indicated absorption at a maximum wavelength of 282 nm. The wavelength suggested that the electron transition π–π* is the absorption of UV spectra typical for triterpenoid compounds that have chromophores in the form of non-conjugated double bonds. FT-IR spectrophotometer characterization data from isolate 1.3 revealed the presence of triterpenoid compounds …

Biological Activity And Solubility Of 5-Methoxy-1,4-Benzoquinone Having Bromoheptyl And Bromodecyl Substituents In The N-Octanol/Water System, Siti Mariyah Ulfa, Fath Dwisari, Laras Pangesti, Mohammad Farid Rahman

Makara Journal of Science

The biological activity and solubility of compounds are influenced by its chemical structure. These properties can be improved by substituting alkyl, alkoxy, and/or haloalkane in the parent skeleton. In this research, the synthesis of 3-(7-bromoheptyl)-2-methyl-5-methoxy-1,4-benzoquinone (3a) and 3-(10-bromodecyl)-2-methyl-5-methoxy-1,4-benzoquinone (3b) was achieved through the decarboxylation reaction. The solubility and biological activity of 3a and 3b were compared with that of thymoquinone (TQ), which acts as an anti-inflammatory agent. Compounds 3a and 3b were successfully synthesized and analyzed using Fourier Transform Infra-Red (FTIR) and Nuclear Magnetic Resonance (NMR). The FTIR spectrum showed the increasing intensity of …

The Effect Of Alcalase Concentration On The Proteins From The Shells Of Litopenaeus Setiferus (White Shrimp), Liam T. Quan

Journal of the South Carolina Academy of Science

Chitin is a naturally abundant polymer that also happens to be biodegradable. Chitin can be used in a variety of different products such as biodegradable plastics, papers, medical products, foods, and medical treatments. To extract chitin, shells must be demineralized and deproteinized. The goal of this experiment was to examine the effect of the protease Alcalase in the deproteinization of litopenaeus setiferus shells. The hypothesis was that if the concentration of Alcalase increased, then the absorbance of proteins in the spectrophotometer reading would increase. The null hypothesis was that if the concentration increased there would be no change in absorption. …
