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
Vanadium Dioxide Conducts Electricity, But Not Heat
By Megan Tan ‘19 Thermal and electrical conductivity need to be proportional in electrical conductive solids. Although several metals can conduct electricity better than they can conduct heat, this phenomenon has only been known to occur at extreme temperatures. However, a recent study led by Professor Junqiao Wu from the University of California, Berkeley and his team of researchers has found that metallic vanadium dioxide … Continue reading Vanadium Dioxide Conducts Electricity, But Not Heat
Hearing Restoration Via Gene Delivery
By Rideeta Raquib ’19 Inner ear disease disrupts a key sense of hearing for many people worldwide. However, gene therapy can treat inner ear disease if reagents are introduced into appropriate cells. A group of researchers from Harvard Medical School and the Massachusetts Hospital managed to effectively restore hearing in mice by utilizing gene therapy. The inefficacy of vectors transferred into hair cells is a … Continue reading Hearing Restoration Via Gene Delivery
Psychopaths May Have Lower than Average Intelligence
by Megan Tan ’19 It is questionable whether psychopaths have a higher or lower IQ than the average human. Previous researchers have investigated the relationship between psychopathy and IQ because there are links to antisocial behavior, violence, and criminal involvement. However, the results have been inconsistent: some studies have demonstrated a negative relationship between the two, whereas others have demonstrated a positive one. To clarify … Continue reading Psychopaths May Have Lower than Average Intelligence
Chicoric Acid Supplementation May Prevent Memory Loss
Patrick Yang ’20 Chicoric acid, a common component in chicory and edible plants, such as lettuce and basil, is a known antioxidant that has anti-HIV and anti-obesity qualities. It can also reduce inflammation caused by high-fat diets and is rapidly distributed to tissues, including the brain, after ingestion. Because of its anti-inflammatory trait and ability to cross the blood-brain barrier, it may be able to … Continue reading Chicoric Acid Supplementation May Prevent Memory Loss
