New Disney Study Suggests More Effective 3D Printing Designs

By Caleb Sooknanan ’20 Compliant mechanisms are mechanisms that can transfer forces or displacements to other points along their bodies. 3D printing can be used to quickly and effectively design compliant mechanisms for commercial use, but more work is needed to understand how such devices can be printed. Doctor Bernhard Thomaszewski and researchers from Disney Research Zurich in Switzerland devised a computational tool that would … Continue reading New Disney Study Suggests More Effective 3D Printing Designs

The Effects of Carotenoids on Cognitive Ability

By Caleb Sooknanan ’20 Lutein — a carotenoid or pigment from green foods such as spinach and kiwifruit — can be quantified in central nervous system tissue, making it a useful way of evaluating diet’s effect on the brain. However, scientists are still determining whether higher lutein amounts yield cognitive ability improvements. Doctor Naiman A. Khan and researchers at the University of Illinois at Urbana-Champaign … Continue reading The Effects of Carotenoids on Cognitive Ability

3D-Printed Ear Devices Detect Core Body Temperature

By Caleb Sooknanan ’20 Healthcare sensors are frequently used to detect skin temperature, but more research is needed to design a device that can pinpoint core body temperature levels and help doctors predict the likelihood of fever, fatigue, and other physiological phenomena. Professor Ali Javey and researchers at the University of California, Berkeley designed a printable smart device that — when placed on a patient’s … Continue reading 3D-Printed Ear Devices Detect Core Body Temperature

Neutrophilic Pleocytosis is Connected to Viral CNS Infections

By Caleb Sooknanan ’20 Viral central nervous system (CNS) infections are often associated with cerebrospinal fluid (CSF) lymphocytic pleocytosis, or an increase in the fluid’s white blood cell count. However, these infections are also connected to neutrophilic pleocytosis, an increase in the fluid’s neutrophil count. The clinical and prognostic significance of CSF neutrophilic pleocytosis remains unknown in patients. Doctor Siraya Jaijakul and researchers at the … Continue reading Neutrophilic Pleocytosis is Connected to Viral CNS Infections

Capsule Robots Can Be Used for Biosensor Implantation

By Caleb Sooknanan ’20 Biosensors have become increasingly practical within the medical field, as they can detect different biometrics such as heart rate and body temperature levels. However, current biosensors can wear out quickly and elicit health problems such as trauma. Many efforts — especially in the area of capsule robotics — have been made to develop biosensors that are noninvasive and effective at monitoring … Continue reading Capsule Robots Can Be Used for Biosensor Implantation

Arthropod Toxins Used to Engineer Mosquito-Killing Fungi

By Caleb Sooknanan ’20 Mosquitoes are known to transmit potent diseases — particularly malaria and dengue fever — among humans. The impact of these diseases is most apparent in sub-Saharan Africa, where over 200 million cases of malaria are reported annually. Many disease control programs in the region have used broad-spectrum insecticides to eliminate mosquitoes and reduce the spread of vector-borne diseases. However, malarial mosquitoes … Continue reading Arthropod Toxins Used to Engineer Mosquito-Killing Fungi

Combination Therapies Reduce Treg Functions in CHC Patients

by Caleb Sooknanan ’20 Regulatory T-Cells, or Tregs, are important contributors to the development of chronic hepatitis C (CHC) infections in patients. Oral antiviral agents are the most common treatments for CHC infections in most Western countries, while pegylated interferon (PEG-IFN) treatment is the standard therapy in many Asian countries. PEG-IFNs are interferons that attach to polyethylene glycol molecules to trigger sustained virological responses (SVR) … Continue reading Combination Therapies Reduce Treg Functions in CHC Patients

Computational Fluid Dynamics Can Be Used to Treat Oral Cancer

by Caleb Sooknanan ’20 Surgical procedures have often been used to treat oral cancer. However, these procedures can cause oral dysfunction — often in the form of speech and breathing difficulties — and thereby harm respiratory organs. To preserve organ function, intra-arterial chemotherapy (IAC) has become a valuable form of treatment. IAC releases more anticancer agents into tumor-feeding arteries than intravenous systemic chemotherapy. However, anticancer … Continue reading Computational Fluid Dynamics Can Be Used to Treat Oral Cancer

New Species of Fungi Discovered in Chinese Cotton Plants

by Caleb Sooknanan ’20 Dr. Xiao-Lin Li and researchers at Zhejiang University in China recently discovered a new fungal species, now identified as Scopulariopsis gossypii. The species was found in the vascular bundles of cotton plants infected by Verticillium dahlia, a pathogen of economic importance throughout the city of Hangzhou. Scientists have already associated the genus Scopulariopsis with fungi that are isolated from air and … Continue reading New Species of Fungi Discovered in Chinese Cotton Plants

The Effects of Insecticidal Nets on Asymptomatic Malaria in India

Caleb Sooknanan ‘20 Over the past decade, mosquitoes have been subject to many vector control strategies in order to control the spread of Malaria. Long-lasting insecticidal nets (LLINs) have been among the most effective, as their distribution has reduced global malaria morbidity by 45% since 2000. However, a large proportion of malarial infections remain asymptomatic, likely preventing malaria elimination programs from being executed to the … Continue reading The Effects of Insecticidal Nets on Asymptomatic Malaria in India

Integrating Synthetic Biology with Hepatogenous Diabetes Treatments

Caleb Sooknanan ‘20 Hepatogenous diabetes is a condition often characterized by the comorbid presence of type 2 diabetes with chronic liver disease. A major factor in this condition is insulin resistance (IR), an asymptomatic disease state in which impaired insulin signaling causes organ dysfunction. Current therapies that target IR are limited and generally inapplicable for patients with liver disease. Dr. Shuai Xue and researchers at … Continue reading Integrating Synthetic Biology with Hepatogenous Diabetes Treatments

A Mechanical Thorax for CPR Simulation

Caleb Sooknanan ’20 For the past few decades, cardiopulmonary resuscitation (CPR) guidelines have been regulated on the basis of chest compression, medication procedures, and other criteria. However, the circulation generated via CPR varies with intensity and duration of compressions, which can be inconsistent. As studies evaluating such inconsistencies have been relegated to animal or computer simulations due their medical and ethical concerns, Dr. Stefan Eichhorn … Continue reading A Mechanical Thorax for CPR Simulation
