Herbal Extracts As Neuroprotective Agents In An In-Vitro Model Of Aluminum Neurotoxicity, Nada Ezzelarab

Theses and Dissertations

Background: Aluminum toxicity due to environmental or industrial exposure, medical applications, or from cooking utensils is a serious medical problem. The current study aims to investigate three herbal extracts: pomegranate peel extract, Achillea fragrantissima extract, and papaya fruit extract to combat this neurotoxicity.

Methods: Chemical characterization of the three extracts were evaluated using HPLC MS while their neuroprotective activity was assayed using MTT assay on SHSY5Y cells and nitric oxide levels.

Results: Using HPLC-MS chromatography, we have identified twenty-one compounds in the hydro-alcoholic Achillea fragrantissima, seventeen were determined in the pomegranate peel, eleven were assessed in the Carica papaya …

‘Am I Turning Into A Man?’ Experiences Of Pakistani Women With Pcos, Rida E Zehra Zaidi

MSJ Capstone Projects

According to the National Institutes of Health, 20 – 25% of all regularly ovulating women have PCOS. This disorder has a range of visible symptoms including excessive weight gain, hirsutism, acne, and hair loss among others. These symptoms make it difficult for women with the syndrome to fit the femininity ideals of the society, as it demands female bodies to be slim, smart, hair less, and to have porcelain skin and regular menstrual cycles. Women with PCOS and other health problems in Pakistan spend all their lives fighting unnecessary battles. This struggle has severe impacts on their physical and mental …

Diversity Oriented Synthesis, Characterization And Anti-Cancer Activity Of Killer Peptide Nucleolipid Bioconjugates, Niki K. Rana

Seton Hall University Dissertations and Theses (ETDs)

The killer peptide sequence D-(KLAKLAK)₂ has been originally designed and developed as an antibacterial agent. Despite having excellent cytotoxicity towards bacteria, this sequence maintains low cell cytotoxity in malignant mammalian cell types such as cancer. The chemical basis for its selectivity has been attributed to its poly(cationic) amphiphilic nature, which facilitates cell permeability across the negatively charged bacterial membrane, but with limited permeability across the zwitterionic membrane of mammalian cells. The positively charged D-(KLAKLAK)₂ sequence has been found to accumulate on the surface of the mitochondria causing dissipation of the negatively charged mitochondrial membrane potential. This charge disruption …
