A New Potential Vaccine Candidate for Staphylococcus aureus

Alex Moir ’23 Staphylococcus aureus (S. aureus) is a bacterium often found in both skin and the upper respiratory tract. Despite its native status in the human body, S. aureus can also act as an opportunistic pathogen in immunocompromised hosts. Efforts to create an effective S. aureus vaccine have so far proven unsuccessful due to the diverse array of immunoevasive strategies S. aureus employs. Specifically, … Continue reading A New Potential Vaccine Candidate for Staphylococcus aureus

Uncovering the Link Between SARS-CoV-2 and Vascular Dysregulation

Alex Moir ’23 SARS-CoV-2 is the virus currently driving the COVID-19 pandemic. SARS-CoV-2 has been shown to infect ciliated epithelial cells (EPCs), which line the upper respiratory tract, through a cell surface receptor known as angiotensin-converting enzyme 2 (ACE2), resulting in Acute Respiratory Distress Syndrome (ARDS). ARDS is characterized by both pulmonary and vascular dysregulation, which presents as shortness of breath, low oxygen, and poor … Continue reading Uncovering the Link Between SARS-CoV-2 and Vascular Dysregulation

Hearing Loss and Cognition: The Role of Hearing Aids, Social Isolation and Depression

Sabah Bari ’24 Individuals with hearing loss have been correlated with low cognitive functioning and incident dementia. Cognitive impairment includes problems with memory, having trouble with learning new tasks, concentrating or making decisions that affect their everyday life. Dementia is a form of cognitive impairment, in the sense of, loss of memory, language and problem solving. Both conditions can limit an individual’s function and interfere … Continue reading Hearing Loss and Cognition: The Role of Hearing Aids, Social Isolation and Depression

The Tubarial salivary glands: A potential new organ at risk for radiotherapy.

Thumyat Noe ‘ 23 Production of saliva by the salivary gland system is important for speech production, chewing, swallowing, tasting, and maintaining dental hygiene. Previously, physicians and scientists were only aware of the existence of three paired major glands and 1000 minor glands in the salivary gland system. However, researchers from the Netherlands have recently discovered an unknown bilateral structure posterior in the nasopharynx with … Continue reading The Tubarial salivary glands: A potential new organ at risk for radiotherapy.

Spatially Distributed Representation of Taste Quality in the Gustatory Insular Cortex of Behaving Mice

Sabah Bari ’24 The brain’s response to taste is found within the gustatory cortex. The sense of taste can be affected by our other senses such as smell, hearing, and sight. The purpose of this study was to understand the processes of visual, auditory and somatosensory cortices and how they respond to similar sensations. The somatosensory cortex has a role in processing somatic sensations, which … Continue reading Spatially Distributed Representation of Taste Quality in the Gustatory Insular Cortex of Behaving Mice

Cannabis Use and the Course of Schizophrenia: 10-year Follow-Up After First Hospitalization

Thumyat Noe ’23 The relationship between cannabis use and course of schizophrenia have been extensively studied by researchers, as increased consumption of cannabis is often observed in individuals with schizophrenia. For the most part, results of these studies have been inconclusive. Some studies have reported that cannabis use is associated with less severe negative symptoms of schizophrenia, while other studies have suggested that cannabis users … Continue reading Cannabis Use and the Course of Schizophrenia: 10-year Follow-Up After First Hospitalization

Effects of Huntington’s Disease Pathology Observable in Retinal Function

Vignesh Subramanian ’24 Huntington’s disease (HD) is a genetic neurodegenerative disorder that causes progressive development of involuntary movements and decline of memory and cognitive abilities. The disease is characterized by the aggregation of abnormally long huntingtin protein (mHtt), a product of mutations in the HTT gene that cause excessive ‘CAG’ nucleotide sequence repeats within the protein’s coding DNA sequence. Such mHtt aggregation triggers cell death … Continue reading Effects of Huntington’s Disease Pathology Observable in Retinal Function

Napping appears to have significant beneficial effects on long-term memory-retention over cramming

Priyanshi Patel ’22 Currently, there is extensive research on the cognitive effects of daytime naps, but not whether naps are a practical way to assist learning. Naps can reduce the likelihood of forgetting episodic memory consisting of life events and experiences. Prior research surrounding memory improvements have led to the idea that naps may be used as a pedagogical tool.  However, there is little evidence … Continue reading Napping appears to have significant beneficial effects on long-term memory-retention over cramming

Discovering the Role of the Neuropilin Pain Pathway in Asymptomatic COVID-19 Cases

Aditi Kaveti ’23 In the United States, there have been more than 7 million documented cases of COVID-19, leading to over 200,000 deaths nationwide. This high number of cases is due to the rapid spread of the deadly disease, which is caused by a virus called SARS-CoV-2. Many researchers believe that the rapid spread can be in part attributed to a high number of asymptomatic … Continue reading Discovering the Role of the Neuropilin Pain Pathway in Asymptomatic COVID-19 Cases

Evaluating Subgroups of Patients with Spinal Epidural Abscess

Panayiota Siskos ’23 Spinal epidural abscess (pus that has built up in tissue, organs, or spaces in the body) is a rare infection that has rising incidence, as well as high morbidity and mortality due to delayed diagnosis. These abscesses are in the epidural region (located between the outermost layer of tissue and the inside surface of bone containing the spine that runs down its … Continue reading Evaluating Subgroups of Patients with Spinal Epidural Abscess

Antibody Conditioning Enables Tolerance of Glial Grafting

Vignesh Subramanian ’24 In the central nervous system (CNS) and peripheral nervous system (PNS), glia are supportive cells that form myelin sheaths, or coatings, that insulate and protect neurons. Activated glial cells are also capable of producing growth factors such as BDNF and bFGF that trigger neuroinflammation, inducing a prolonged state of pain which alerts an organism to potential nerve injury. As such, various subtypes … Continue reading Antibody Conditioning Enables Tolerance of Glial Grafting

Melittin: A Natural Peptide from Bee Venom Which Induces Apoptosis in Human Leukemia Cells

Thumyat Noe ’23 Past research has shown that honeybee’s venom has the potential to treat various diseases such as arthritis, chronic pain, cancer, and atopic dermatitis. The venom mostly consists of peptides and low molecular weight compounds such as sugars and amino acids. Melittin is one of the peptides found within honeybee’s venom and possesses the most bioactive properties among all the compounds in the … Continue reading Melittin: A Natural Peptide from Bee Venom Which Induces Apoptosis in Human Leukemia Cells
