Cushing’S Reflex And Bradycardic Arrest In Cryptococcal Meningitis, Scott Briggs, Trent Malcolm May 2021

Cushing’S Reflex And Bradycardic Arrest In Cryptococcal Meningitis, Scott Briggs, Trent Malcolm

Rowan-Virtua Research Day

Cushing’s reflex is a physiologic response to maintain cerebral perfusion pressure with elevated systolic blood pressure, widened pulse pressure, and bradycardia occurring in the setting of elevated intracranial pressure (ICP). The proposed mechanisms for reflexive bradycardia include ischemia to medullary brain tissue and compression of the intracranial segment of the vagus nerve leading to parasympathetic activation. (1) In acutely elevated ICP, bradycardia is a late finding of worsening intracranial pathology suggestive of impending herniation and cardiovascular collapse.

Cryptococcal meningitis has been identified by Infectious Disease Society of America for its association with elevated ICP. (2) Variety of pathogenic mechanisms occurring …

Multiple Myeloma With Dual Expression Of Kappa And Lambda Light Chains, Monica Patel, Akash Patel, Yvette Wang

Rowan-Virtua Research Day

Multiple myeloma (MM) is a malignancy of plasma cells that accounts for approximately 1 to 2 percent of all cancers and about 17% of all hematologic malignancies.

Plasma cells normally produce antibodies and provide a defense mechanism for the body to fight infections.

Antibodies typically consist of two heavy chains (IgG, IgA, IgM, IgD and IgE) and two light chains (kappa and lambda).

Most cases of MM have malignant plasma cells producing monoclonal (M) proteins, most common being IgG about 52% of the time (1).

Only about 2% of these myeloma cases were also found to secrete more than one …

Rowan-Virtua Research Day

Constipation is an extremely common chief complaint in the emergency department, contributing to approximately 700,000 emergency department visits in 2011. Severe constipation can result in stercoral colitis, which in turn can lead to development of ulceration and colonic perforation leading to fatal peritonitis. As a result, prompt recognition and treatment of this condition with bowel cleansing and fecal disimpaction are often recommended. Here, we will discuss a case of a 62-year-old male with a history of schizoaffective disorder who came into the Emergency Department (ED) hypotensive with stercoral colitis secondary to severe constipation. Following bedside fecal disimpaction, the patient developed …


The Impact Of Exercise On Pregnant Women Aged 18-40 And Fetal Development, Jinisha Patwa May 2021

The Impact Of Exercise On Pregnant Women Aged 18-40 And Fetal Development, Jinisha Patwa

Rowan-Virtua Research Day

68% of those who performed minimum level exercise prior to pregnancy stopped completely during early pregnancy.

Women stop exercising during pregnancy due to worries about the impact it may have on the development of the fetus.

Starting moderate-intensity, weight-bearing exercise early in pregnancy increases placental growth rate and volume.

Exercise reduces the risks of excess gestational weight gain and high maternal body weight before pregnancy.

Physical exercise reduces the risk of gestational diabetes mellitus.

Rowan-Virtua Research Day

A prominent feature of cocaine abuse is a high risk of relapse even despite prolonged periods of abstinence. Psychosocial stress is thought to be a major contributor to the onset of cocaine craving and relapse in human substance abusers, yet most preclinical models of stress-induced relapse employ physical stressors (e.g., unpredictable footshock) or pharmacological stressors (e.g., yohimbine to elicit a drug seeking response) and do not rely upon psychosocial stress per se. Importantly, social stressors are well known to activate distinct neural circuits within the brain as compared to other stressors. It is therefore possible that currently available animal models …

Lip Biopsy Trends In The United States: A 7-Year Review Of Medicare Provider Utilization And Payment Database, Nardin Awad, Fady Awad, Amanda Azer

Rowan-Virtua Research Day

Biopsy of the lip is a procedure most used by dermatologists in order to obtain histopathological evaluation of a lesion. It has remained the definitive method of diagnosis for many pathologies, including malignancy. However, although the incidence of lip malignancy has been relatively unchanged since 2012, the number of lip biopsies performed has not followed the same trend, but rather steeply declined since. In this study, the national trends in lip biopsies are evaluated. The Medicare Provider Utilization and Payment (MPUP) database was used to evaluate these practice trends in Medicare providers.

Replication Protein A (Rpa) Targeting Of Uracil Dna Glycosylase (Ung2), Derek Chen, Brian P Weiser May 2021

Replication Protein A (Rpa) Targeting Of Uracil Dna Glycosylase (Ung2), Derek Chen, Brian P Weiser

Rowan-Virtua Research Day

Replication Protein A (RPA) is a single stranded DNA binding protein which stabilizes ssDNA for replication and repair. One function of RPA is to bind the DNA repair enzyme uracil DNA glycosylase (UNG2) and direct its activity towards ssDNA dsDNA junctions.

UNG2 removes uracil bases from DNA which can appear through dUMP misincorporation or through cytosine deamination. If uracil is present instead of a cytosine, then the original GC pair becomes a GU pair. The uracil will then base pair to adenine in the replicated daughter strand. This results in a GC → AT mutation that could contribute to cancer …

Substrate-Dependent Modulation Of Sirt2 By A Fluorescent Probe, 1-Aminoanthracene, David Bi, Prashit Parikh, Jie Yang, Brian P Weiser

Rowan-Virtua Research Day

Sirtuin isoform 2 (SIRT2) is an enzyme that catalyzes the removal of acyl groups from lysine residues. SIRT2’s catalytic domain has a hydrophobic tunnel where its substrate acyl groups bind. Here, we report that the fluorescent probe 1-aminoanthracene (AMA) binds within SIRT2’s hydrophobic tunnel in a substrate-dependent manner. AMA’s interaction with SIRT2 was characterized by its enhanced fluorescence upon protein binding (>10-fold). AMA interacted weakly with SIRT2 alone in solution (Kd = 37 μM). However, when SIRT2 was equilibrated with a decanoylated peptide substrate, AMA’s affinity for SIRT2 was enhanced ∼10-fold (Kd = 4μM). The peptide’s decanoyl chain and …
