Modulation Of Tlr4/Nf-Κb, Nrf2/Ho-1 And Pi3k/Akt Signaling By Cilostazol Mitigates Lipopolysaccharide-Induced Septic Acute Kidney Injury, Ahmed F. Mohamed, Helmy M. Sayed, Hala F. Zaki, Marwa M. Safar

Bulletin of Faculty of Pharmacy Cairo University

Cilostazol was investigated as a protective agent against lipopolysaccharide (LPS)-associated acute kidney damage in mice. Cilostazol (50 mg/kg/day; p.o) administered for 7 consecutive days before a single LPS dose (2 mg/kg; i.p) hampered serum creatinine and cystatin C as well as renal KIM-1 and NGAL, repressed TLR4 and MYD88 transcription as well as NF-κB p65, IL-1β and MDA content, boosted Nrf-2 mRNA expression, HO-1 activity and GSH content. This was synchronous with an upregulation of p-PI3K and p-Akt expressions. Collectively, cilostazol prevented LPS renal injury which might correspond to modulation of TLR4/NF-κB, Nrf2/HO-1 and PI3K/Akt pathways.

Antibody-Dependent Enhancement Activity Of A Plant-Made Vaccine Against West Nile Virus, Amber M. Paul, Haiyan Sun, Dhiraj Acharya, Huafang Lai, Junyun He, Fengwei Bai, Qiang Chen

Publications

West Nile virus (WNV) causes annual outbreaks globally and is the leading cause of mosquito-borne disease in Unite States. In the absence of licensed therapeutics, there is an urgent need to develop effective and safe human vaccines against WNV. One of the major safety concerns for WNV vaccine development is the risk of increasing infection by related flaviviruses in vaccinated subjects via antibody-dependent enhancement of infection (ADE). Herein, we report the development of a plant-based vaccine candidate that provides protective immunity against a lethal WNV challenge mice, while minimizes the risk of ADE for infection by Zika (ZIKV) and dengue …

Phase 1a Clinical Study For Q-Griffithsin Intranasal Spray For Prevention Of Coronavirus, Megan Bezold, Kenneth Palmer, Nobuyuki Matoba, Elizabeth Cash

Posters-at-the-Capitol

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly transmissible virus that causes acute respiratory disease with possible long-term complications, known as coronavirus disease 2019 (COVID-19). Griffithsin (GRFT; including the oxidation-resistant variant Q-GRFT used in this study) is an algal carbohydrate-binding protein exhibiting antiviral effects against many enveloped viruses, including all major variants of SARS- CoV-2 reported to date. Q-GRFT has been recombinantly manufactured in Nicotiana benthamiana plants, thoroughly purified, and formulated as an intranasal spray designed to be developed as a non-vaccine broad-spectrum prophylactic product for acute use. This is the first-in-human, randomized, double-blind, placebo-controlled study. The …

Overexpression Of Abcc1 And Abcg2 Confers Resistance To Bmn-673, A Poly (Adp-Ribose) Polymerase (Parp) Inhibitors, Qiuxu Teng

Theses and Dissertations

Cancer remains a growing public health challenge worldwide. Although the development of chemotherapies has effectively reduced the cancer death rate and improved patients’ prognosis, the frequent occurrence of multi-drug resistance (MDR) in cancer has caused impairments on the efficacy of many structure-unrelated anticancer agents, leading to treatment failure and recurrence. One of the most common causes of MDR is the overexpression of ATP-binding cassette (ABC) transporters on cancer cell membranes, which transport anticancer drugs out of cancer cells, thereby reducing the intracellular drug concentration. BMN-673 (talazoparib) is a potent poly (ADP-ribose) polymerase (PARP) inhibitor that is approved for BRCA-mutated HER2-negative …

Effects Of Elevated Extracellular Dopamine On Astrocytes In The Nucleus Accumbens, Mengfan Xia

Theses and Dissertations--Pharmacology and Nutritional Sciences

Nucleus accumbens is involved in processing of motivational and affective behaviors and plays a significant role in development and maintenance of substance use. Released from the ventral tegmental area into the nucleus accumbens, the mesolimbic dopamine controls incentive salience and facilitates learning of reinforcement and reward-related motor functions. Recent studies reveal that, in the context of cocaine exposure, dopamine transmission in the ventromedial striatum is pivotal to the regulation of initial drug use. Astrocytes, a major subpopulation of the brain glial cells, are an active component of the so-called tripartite synapse and communicate with neurons through the release of transmitters …

Nutritional & Colorectal Health, Tariq A. Alam, Brittany R. Rice, Sara B. Police

Journal of Pharmacology & Nutritional Sciences

Kentucky has the highest incidence and mortality rate of all site cancers, and Kentuckians residing in the Appalachian region often have worse outcomes, where cancer is a leading cause of death. Focusing on colorectal cancer (CRC) specifically, Kentucky ranks first nationwide for incidence (50 cases per 100,000 people) and fifth for mortality (about 17 deaths per 100,000 people). The Kentucky Colon Cancer Screening Program increased screening rates and reduced mortality since its launch. Yet, CRC remains a leading cause of death for Kentuckians. Risk factors for CRC include increasing age as well as a history of inflammatory bowel disease (IBD) …

Modulation Of Opioid-Induced Respiratory Depression By Stimulants And Their Associated Monoaminergic Receptor Mechanisms In Mice Using Whole Body Plethysmography, Harrison J. Elder

Theses and Dissertations

Opioid overdose and associated deaths involving opioid-induced respiratory depression (OIRD) began to accelerate beginning in 2015 with the emergence of illicitly manufactured fentanyl and its analogs and currently represents one of the most significant public health challenges in the United States. The increases in overdose deaths have occurred despite the increased availability of the opioid overdose reversal agent, naloxone, to first responders and the public. This new phase of the opioid epidemic has been paralleled by substantial growth in the co-use of opioids with stimulants, particularly methamphetamine. The objective of this dissertation is to ascertain whether fentanyl is particularly resistant …

Covid-19 Vaccination And Alcohol Consumption: Justification Of Risks, Pavel A. Solopov

Bioelectrics Publications

Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, pharmaceutical companies and research institutions have been actively working to develop vaccines, and the mass roll-out of vaccinations against COVID-19 began in January 2021. At the same time, during lockdowns, the consumption of alcoholic beverages increased. During the peak of vaccination, consumption remained at high levels around the world, despite the gradual relaxation of quarantine restrictions. Two of the popular queries on search engines were whether it is safe to drink alcohol after vaccination and whether this will affect the effectiveness of vaccines. Over the past two …

Novel Strategies In Head And Neck Tumor Therapy; Contribution Of Senescence In Therapy Response, And Resistance Development After Cisplatin Treatment, Fereshteh Ahmadinejad

Theses and Dissertations

Therapeutic outcomes achieved in head and neck squamous cell carcinoma (HNSCC) patients by concurrent cisplatin-based chemoradiotherapy initially reflect both tumor regression and tumor stasis. However, local, and distant metastasis and disease relapse as well as cisplatin-induced resistance are common in HNSCC patients. In the current work, we demonstrate that cisplatin treatment induces senescence in both p53 wild- type HN30 and p53 mutant HN12 head and neck cancer models. We also show that tumor cells can escape from senescence both in vitro and in vivo. We further established a cisplatin-resistant cell line from HN30 parental cell line that underwent brief senescence …

Effectiveness Of A Long-Acting Cocaine Hydrolase In Metabolizing Cocaine And Its Physiologically Active Metabolites, Linyue Shang

Theses and Dissertations--Pharmacy

Cocaine is a widely abused, hepatotoxic drug without an FDA-approved pharmacotherapy specific for cocaine addiction or overdose. Cocaine-induced toxicity in animals and humans is due to its multiple physiological effects on the central nervous system, cardiovascular system, etc. The toxicity of cocaine is highly complex, as its metabolites also contribute to the toxicity. Notably, the combination of cocaine and alcohol is common among drug users and can produce additional metabolites. Some of the metabolites are more toxic than cocaine itself. Hence, to develop an ideal therapeutic candidate, the candidate should not only account for cocaine but should also detoxify other …

Age-Associated Increase Of Gamma Delta T Cells In Visceral Adipose Tissue And Mechanisms Of Their Accumulation, Sujata Mukherjee

Theses and Dissertations--Pharmacology and Nutritional Sciences

Chronic systemic inflammation, known as inflammaging is considered a hallmark of aging and associated diseases. While adipose tissue has long been considered only as a caloric reservoir regulating systemic energy homeostasis, research in the past couple of decades substantiate its endocrine function to secrete an array of inflammatory mediators and hormones, which have physiological effects on multiple organ systems, and contribute to inflammaging. Redistribution of adipose tissue from subcutaneous to visceral depots, changes in the immune profile and the chronic inflammatory state are among the major sources of adipose tissue dysfunction with aging.

This dissertation is focused on identifying and …

Chemical Immobilization Of Helicopter-Captured Elk (Cervus Canadensis) And Survival Of Elk Calves In Southeastern Kentucky, Kathleen E. Williams

Theses and Dissertations--Forestry and Natural Resources

Safe and effective chemical immobilization is critical to minimize stress and risk of injury when capturing free-ranging, wild ungulates. Many traditionally favored high potency opioids have been phased out or become unavailable because of increased regulations, leading to the development of two pre-mixed combination drugs, butorphanol-azaperone-medetomidine (BAM) and nalbuphine-medetomidine-azaperone (NalMed-A). Both drugs have been used to chemically immobilize ungulates, but their efficacy has not been documented in elk captured and transported via helicopter. During 2020 – 2022, we chemically immobilized helicopter-captured female elk (Cervus canadensis) with a single IM-injection of BAM (n = 41) or NalMed-A (n = …

Vapourized Cannabis Extract Administration Impairs Memory And Alters Neural Activity In Laboratory Rats, Megan Chladny

Theses and Dissertations (Comprehensive)

Although people have smoked cannabis for millennia, administration of cannabis by heating the dried plant material or distilled extracts to a temperature just below the combustion point (i.e., vapourization or "vaping") has rapidly increased over the past few years (Javadi-Payder, Cole, and Taffe, 2018; Manwell, Charchoglyan, Brewer, Matthews, Heipel, and Mallet, 2014). Conversely, most of the cannabinoid research using rodent models has used parenteral routes of administration to examine the effects of purified cannabis extracts such as ∆⁹-tetrahydrocannabinol (THC), making it difficult to directly compare laboratory research to human drug use. Building on previous studies showing that THC …

Mitoq Alleviates Hippocampal Damage After Cerebral Ischemia: The Potential Role Of Sirt6 In Regulating Mitochondrial Dysfunction And Neuroinflammation, Ayman A. Ibrahim, Sherif S. Abdel Mageed Dr, Marwa M. Safar Prof.Dr, Mohammed F. El-Yamany Prof.Dr., Mamdouh A. Oraby Dr.
