Using Positive Image Training to Regain Happiness
By Rideeta Raquib ’19 Emotion-related imagery training is a powerful tool for psychotherapy. Mental imagery can stimulate behavioral and physiological systems more effectively than verbal or informative stimulations. Imagery is less effective on patients diagnosed with generalized anxiety (GAD) because of the tendency to associate bright images with negative occurrences rather than generating positive images. Dr. Svetla Velikova and her team of researchers conducted a … Continue reading Using Positive Image Training to Regain Happiness
High-Elevation Warming is Steeper than Previously Expected
By Megan Tan ’19 The Earth is warming at about two degrees annually at sea level. Though it is estimated that high-elevation warming occurs more steeply, it is difficult to measure due to environmental factors such as radiation and humidity which have made it challenging to accurately quantify past temperature changes. Shannon E. Loomis, a postdoctoral fellow at the Department of Earth, Environmental, and Planetary … Continue reading High-Elevation Warming is Steeper than Previously Expected
Airway Smooth Muscle Relaxant Finally Identified
By Patrick Yang ’20 Asthma, characterized by its iconic inhalers and abrupt episodes of coughing and wheezing, affects approximately 334 million people worldwide. The inflammatory disease is caused by the prolonged contraction of airway smooth muscles, which triggers difficulty with breathing. Despite our understanding of asthma’s symptoms, the mechanism behind asthma is still a mystery. Scientists speculate that normal airway epithelium, or cells composing the … Continue reading Airway Smooth Muscle Relaxant Finally Identified
Homing Neural Stem Cells Deliver Direct Cancer Treatment
By Patrick Yang ’20 With average survival for glioblastoma patients at approximately 12-15 months, speed is of essence for glioblastoma cancer treatment. Currently, promising stem cell research has found that neural stem cells naturally migrate towards the chemical signals released by glioblastoma cells. If these neural stem cells are engineered to contain cytotoxic agents, they can deliver cancer treatment directly to cancer cells. However, the … Continue reading Homing Neural Stem Cells Deliver Direct Cancer Treatment
Hospital Sepsis Is Dependent on Toxins for Survival
By Patrick Yang ’20 The hospital is considered a place of treatment, but hospitalization also runs the risk of bacterial sepsis – an often fatal immune response to bacterial infection. Bacterial sepsis frequents patients who are connected to medical devices like needles and catheters, which can easily launch the bacteria into the bloodstream. That infection, compounded with an already compromised immune system, can prove to … Continue reading Hospital Sepsis Is Dependent on Toxins for Survival
Blunted Neural Response to Rewards as a Prospective Predictor of the Development of Depression in Adolescent Girls
By Ericka Berman Previous studies have shown that during adolescence, rates of depression increase markedly, and girls tend to have rates of depression twice as high as boys. Depressed adults were also shown to exhibit a decreased behavioral response to a reward and less brain activity in regions associated with reward processing in comparison to healthy adults. Dr. Brady Nelson and his team … Continue reading Blunted Neural Response to Rewards as a Prospective Predictor of the Development of Depression in Adolescent Girls
Efficacy of Quetiapine Monotherapy in Posttraumatic Stress Disorder: A Randomized, Placebo-Controlled Trial
Ericka Berman Posttraumatic Stress Disorder (PTSD) is a debilitating illness affecting approximately 7.8% of people in the U.S. over the course of their lifetime. As of now, two medications are approved in the U.S. to treat PTSD, but both treatments have limited success. Characteristics of the antipsychotic medication quetiapine suggest it may be helpful in treating PTSD symptoms of re-experiencing … Continue reading Efficacy of Quetiapine Monotherapy in Posttraumatic Stress Disorder: A Randomized, Placebo-Controlled Trial
Norepinephrine Transporter in Major Depressive Disorder: A PET Study
Ericka Berman Major depressive disorder (MDD) is a debilitating illness characterized by low mood and loss of interest in activities. In MDD, the neurotransmitter norepinephrine is believed to be dysregulated, contributing to the depressive symptoms. The goal of this study was to test norepinephrine transporter availability in patients with MDD in attempt to identify potential associations with clinical symptoms. Previous studies have looked … Continue reading Norepinephrine Transporter in Major Depressive Disorder: A PET Study

Medicinal Properties Discovered in Certain Toad Species
By Rideeta Raquib ’19 Traditional medicinal compounds utilized to treat various diseases, ranging from stomach disorders to some types of cancers, are common in toads, specifically the Bufonidae family. Scientists at the University of Panama, Panama’s government research center INDICASAT AIP, Vanderbilt University in Tennessee, and Acharya Nagarjuna University in Guntur, India, came together to identify several chemical components of the traditional medicines acquired from … Continue reading Medicinal Properties Discovered in Certain Toad Species
Are Men Smarter than Women?
By Megan Tan ‘19 Gender stereotypes commonly associate intellectual brilliance with men. These stereotypes explain the gender imbalances in fields typically associated with brilliance, like physics and mathematics. Lin Bian, a graduate student from the University of Illinois, set out to find the origin of this stereotype. It was found that by the age of six, girls are less likely to associate their gender with … Continue reading Are Men Smarter than Women?
Fat Metabolism Activated by Brain Hormone
By Rideeta Raquib ’19 The central nervous system is essential in regulating different parts of the body. Serotonin (5-hydroxytryptamine, 5-HT), a neuromodulator, has been related to feeding and metabolizing, as well as burning fat. Biologists at the Scripps Research Institute set out to identify a neuropeptide ligand and its cognate receptor that makes up the 5-HT neuroendocrine axis. The study was conducted on a roundworm … Continue reading Fat Metabolism Activated by Brain Hormone
