Citrus Aurantium Peels Secondary Metabolites Prevents Cell Senescence On Human Fibroblasts Cells By In Vitro And Bioinformatics Studies, Nur Dina Amalina, Sri Wahyuni, Harjito H, Meiny Suzery, Bambang Cahyono

The Thai Journal of Pharmaceutical Sciences

Aging is a medical problem affecting about 800 million people worldwide. However, the molecular mechanism of aging and aging-related disease has not yet been explored. Skin aging is a complex biological process primarily due to cellular senescence. Cellular senescence is an irreversible growth arrest that caused tissue to lose their cell-specific functionality, secreting pro-tumorigenic and pro-inflammatory cytokines, which eventually causes cancer. Citrus aurantium-derived secondary metabolites, including hesperidin, hesperetin, tangeretin, naringenin, nobiletin, and quercetin, are of vital importance to inhibiting aging due to their active properties. However, the effect of C. aurantium-derived secondary metabolites on the cells senescence and its molecular …

Acute Toxicity Of Atrazine, Alachlor, And Chlorpyrifos Mixtures To Honey Bees, Christopher J. Fellows, Troy D. Anderson, Daniel R. Swale

Department of Entomology: Faculty Publications

The acute toxicity of chlorpyrifos and chlorpyrifos-oxon (organophosphorothioate insecticides) was examined alone and in combination with atrazine (triazine herbicide) and alachlor (chloroacetanilide herbicide) to honey bees (Apis mellifera). Atrazine and alachlor were observed to not be acutely toxic to bees at doses up to 10 and 4 μg per bee, respectively. However, atrazine significantly increased chlorpyrifos toxicity by 3-fold while reducing chlorpyrifos-oxon toxicity by 1.8-fold. These changes in toxicity are correlated with significant 1.3- and 1.2-fold inhibition of acetylcholinesterase (AChE) activity in bees exposed to chlorpyrifos and chlorpyrifos-oxon, respectively. Atrazine significantly increased cytochrome P450, general esterase, and glutathione …

Carbon Dots: An Updated Overview On Their Synthesis, Properties, And Applications In Pharmaceutical And Biomedical Sciences, Earle Radha Rani, Majji Usharani, A. Lakshmi Usha

The Thai Journal of Pharmaceutical Sciences

Nowadays, carbon-based materials have acquired more attention in numerous fields including engineering, medicine, and pharmaceutics. As a new class of small carbon nanomaterials, carbon dots are developed due to their excellent physicochemical properties such as spherical shape, non-toxicity, cost effectiveness, facile, biocompatibility, and discrete particles <10 nm in diameter. In 2004, these carbon dots were first discovered accidentally during processing of single walled carbon nanotubes. Carbon dots have created huge excitement due to their advantages such as high water solubility, excellent biocompatibility, and resistance to photo bleaching. Carbon dots show unique properties such as photo stability, low toxicity, fluorescence, photo chemiluminescence, and electrochemiluminescence. Due to these properties, they have a wide range of applications in the field of bioimaging and drug delivery. Carbon dots are classified into two groups: Amorphous based carbon dots and graphene-based quantum dots with sp2 hybridization. The synthesis methods of carbon dots were reviewed along with their advantages and disadvantages. The applications of carbon dots in drug delivery, gene delivery, targeted drug delivery, crossing blood–brain barrier, and bio imaging were discussed.

Effect Of Hyperoxia On Cardiac Pathophysiology In Female Guinea Pig Hearts, Chayapatou Chayawatto

USF Tampa Graduate Theses and Dissertations

Hyperoxia is widely implemented in critical care and ICU patients. The administration of a high concentration of inspired oxygen to the lung can unknowingly cause hyperoxia and thereby damaging the lungs and heart due to oxidative stress. Technically, hyperoxia occurs when the patient receives PaO2 > 200 mmHg. Major research focused on hyperoxia-induced lung injury, but nothing is known on its effect on heart. Our lab is the pioneer in understanding the effect of hyperoxia on cardiovascular remodeling using mice model. Previous results show that mice under 72 hours of hyperoxia present severe cardiac pathophysiology. This research uses Guinea pigs, which …

Screening Pathological Protein Specific Antibodies As Biomarker Discovery Tools For Neurodegenerative Disease, Yitong Li

USF Tampa Graduate Theses and Dissertations

With the increase in the average life span, the incidence of neurodegenerative diseases also increases, among which Alzheimer's disease (AD) and Parkinson's disease (PD) are the two most common types of neurological disorders. AD and PD share the same pathogenic mechanism that involves a class of proteins called beta-amyloid (Aβ), which, under the induction of some factors, changes from its natural monomeric state to the oligomers containing β-sheet, which is neurotoxic and thus leads to cell damage or apoptosis. This study focused on the selection of antibodies used as biomarkers for AD and PD. The selection of antibodies was based …

Coastal Stormwater Pond Pollutants And The Potential For Development Of Antimicrobial Resistance In Vibrio And Enterococcus Bacteria, Cassandra L. Horton

Theses and Dissertations

The Southeastern coastal plain is the most rapidly urbanizing region in the United States. Associated landscape changes which increase imperviousness lead to hydrological cycle alterations, increasing runoff of nonpoint source (NPS) pollution. Urban and agricultural NPS runoff is generally discharged into stormwater ponds, which sequester chemical contaminants, nutrients, and microbes to reduce loading into coastal ecosystems. Studies of these ponds have indicated elevated levels of trace metals, antimicrobial compounds, and bacterial contamination (SCSGC 2018).

Interactions of aquatic pathogens Vibrio vulnificus and Enterococcus faecium with trace metals (arsenic, copper, zinc) and clinically relevant antimicrobials (triclosan, ciprofloxacin, oxytetracycline) commonly found in coastal …

Asia’S Waste Crisis, Havovi Joshi

Asian Management Insights

Many Asian countries have drawn up national strategies to address waste management through their policy and regulatory frameworks, and put in place policies that promote green growth and sustainable development. However, nations across the continent are at vastly different stages of waste management. On one end, countries like Japan, China, and Singapore are ahead of the curve, and have invested in sound and structured waste management systems. On the other end, less developed nations continue to dispose most of their waste at open dumps.
