Retinal Detachment: What Are The Types And Potential Causes?, Mera Skoblo Jan 2022

Retinal Detachment: What Are The Types And Potential Causes?, Mera Skoblo

The Science Journal of the Lander College of Arts and Sciences

Retinal detachment is one of the few ocular emergencies. Depending on the extensiveness of the detachment, and whether it is macula on or macula off, will affect the patient’s visual acuity after treatment. Therefore, it is vital that after experiencing any common retinal detachment symptoms, the patient sees an ophthalmologist immediately. High-risk factors for retinal detachment include aging, ocular trauma, high myopia, and prior eye surgery. Statistically, the cause of a given retinal detachment often determines the specific type of detachment that occurs. There are three forms of retinal detachment, categorized separately based on their anatomical characteristics.

The Role Of Dichloro(Ethylenediamine) Platinum Ii In Altering Cellular Iron And Copper Transport, Megan Hall

Mahurin Honors College Capstone Experience/Thesis Projects

Approximately 50% of all chemotherapy cancer patients receive a platinum chemotherapeutic during their treatment. Although these drugs are widely utilized, little is known about the cellular transport of platinum drugs. It is hypothesized that platinum utilizes transporters for other metals to enter the cell. Structural differences between compounds are predicted to affect the compounds’ ability to exploit different transporters. Also, different cell types express different transporters. Therefore, compound structure is expected to influence transport of platinum compounds differently in different cell types. This study investigated the role of the platinum drug cisplatin and platinum compound Pt(en)Cl2 in altering iron …

Small G- Protein Regulators Of Islet Beta Cell Function, Suhadinie Sameera Gamage

Wayne State University Dissertations

Defects in insulin secretion from pancreatic islet beta- cells leads to long term complications such as type 2 diabetes mellitus. The mechanism and regulation of glucose stimulated insulin secretion (GSIS) as well as factors contributing to pancreatic islet beta-cell demise are yet poorly understood. Previous work from our laboratory demonstrated that Ras-related C3 botulinum toxin substrate 1 (Rac1), a small G- protein is involved in GSIS as well as in culminating dysfunction under metabolic stress. Cycling of Rac1 between its inactive and active form is considered a vital event in glucose stimulated insulin secretion. This conversion is made possible by …

Browse all Theses and Dissertations

Replication stress can be produced by various exogenous or endogenous factors that perturb the movement of replication forks. To overcome the stress, the cells provoke the DNA replication checkpoint to mobilize several pathways to protect the forks, maintain genome integrity, and promote cell survival. Defects in the replication checkpoint cause forks collapse, leading to chromosomal DNA damage or cell death. Although the replication checkpoint is crucial for genome integrity in all eukaryotes, the underlying mechanisms remains to be fully understood. To investigate the mechanisms of DRC, hydroxyurea (HU), an established inhibitor of ribonucleotide reductase (RNR), has been widely used in …

Poststroke Seizure And Epilepsy: A Review Of Incidence, Risk Factors, Diagnosis, Pathophysiology, And Pharmacological Therapies, Joseph Phan, Mario Ramos, Theodore Soares, Mayur S. Parmar

HPD Articles

Stroke is the most common cause of epilepsy and ultimately leads to a decrease in the quality of life of those affected. Ischemic and hemorrhagic strokes can both lead to poststroke epilepsy (PSE). Significant risk factors for PSE include age < 65age less than 65 years, stroke severity measured by the National Institutes of Health Stroke Scale (NIHSS), cortical involvement, and genetic factors such as TRPM6 polymorphism. The diagnosis of PSE is made by using imaging modalities, blood biomarkers, and prognostic criteria. Electroencephalography (EEG) is currently the gold standard to diagnose PSE, while new combinations of modalities are being tested to increase diagnostic specificity. This literature review uncovers a newly found mechanism for the pathology of poststroke epilepsy. The pathogenesis of early-onset and late-onset is characterized by sequelae of neuronal cellular hypoxia and disruption of the blood-brain barrier, respectively. Interleukin-6 is responsible for increasing the activity of glial cells, causing gliosis and hyperexcitability of neurons. Epinephrine, high-mobility group protein B1, downregulation of CD32, and upregulation of HLA-DR impact the pathology of poststroke epilepsy by inhibiting the normal neuronal immune response. Decreased levels of neuropeptide Y, a neurotransmitter, act through multiple unique mechanisms, such as inhibiting intracellular Ca accumulation and acting as an anti-inflammatory, also implemented in the worsening progression of poststroke epilepsy. Additionally, CA1 hippocampal resonant neurons that increase theta oscillation are associated with poststroke epilepsy. Hypertensive small vessel disease may also have an implication in the temporal lobe epilepsy by causing occult microinfarctions. Furthermore, this review highlights the potential use of statins as primary prophylaxis against PSE, with multiple studies demonstrating a reduction in incidence using statins alone, statins in combination with antiepileptic drugs (AEDs), and statins with aspirin. The evidence strongly suggests that the second generation AEDs are a superior treatment method for PSE. Data from numerous studies demonstrate their relative lack of significant drug interactions, increased tolerability, and potential superiority in maintaining seizure-free status.
