Strain Specific: Microbial Strains Involved in Gut-Brain Signaling

doi:10.22186/jyi.33.3.49-54 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References | PDF Abstract Exploration into the microbial role within behavior and neurologic regulation has been an area of growing interest and research. While in-vitro and in-vivo experimentation has suggested that commensal microbiota play a role within behavioral and neurologic functioning, little distinction has been made about the specific microbes inducing change. In order to understand […]

Brain Tumor Segmentation Using Morphological Processing and the Discrete Wavelet Transform

doi:10.22186/jyi.33.3.55-62 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References | PDF Abstract Medical imaging is key for the successful diagnosis and treatment of brain tumors, but the initial detection of tumors is, by nature, difficult. Image segmentation, a technique often used to aid detection, is highly dependent on the resolution of the segmented image. Many common morphological segmentation methods often suffer from a lack […]

Prevalence and Outcomes of Electrolytes Deficiency in Children under Five with Diarrhea in Mwanza, Tanzania

doi:10.22186/jyi.33.2.46-48 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References | PDF Abstract Dehydration from diarrhea leads to a loss of vital electrolytes in the body. The prevalence of electrolytes deficiency and its outcomes due to diarrhea among children under five in Mwanza, Tanzania was not clearly known, thus this study was performed to determine this statistic. A cohort study was conducted among 66 children […]

Preserving History for Posterity: The Museum Conservator

PDF Nearly 850 million visitors come to American museums each year, according to the American Alliance of Museums. These visitors see the many colorful, historic, and informative exhibits, but few see the important behind-the-scenes work that keeps the exhibits running. This is the job of the conservator.Conservators, such as Rebecca Newberry of the Science Museum […]

Varying Sugars and Sugar Concentrations Influence In Vitro Pollen Germination and Pollen Tube Growth of Cassia alata L.

doi:10.22186/jyi.33.1.42-45 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References | PDF Abstract This study investigates the effects of varying sugars and sugar concentrations on the in vitro germination and tube growth of pollens of Cassia alata L., a known Philippine ornamental and medicinal plant. This aims to add information on the pollination fertilization mechanism of the plant for its possible extensive cultivation. Using a […]

A Transcriptome Study of Borrelia burgdorferi Infection in Murine Heart and Brain Tissues

doi:10.22186/jyi.33.1.28-41 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References | PDF Abstract Lyme disease is the most common vector-borne disease in the United States and is typically caused by the bacterium Borrelia burgdorferi. Although often curable, delayed diagnosis due to nonspecific symptoms risks systemic complications, and some patients experience symptoms despite bacterial clearance from the body. We hypothesized that B. burgdorferi infection induces a […]

Development of a Methodology to Determine Antibiotic Concentrations in Water Samples Using High-Pressure Liquid Chromatography

doi:10.22186/jyi.33.1.19-27 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References | PDF Abstract Antibiotic concentrations are typically measured using solid-phase extraction along with liquid chromatography, but this process is not practical due to a large number of man hours involved. The use of a lyophilizer with high-pressure liquid chromatography (HPLC) is an accurate and cost-effective method of analyzing antibiotics in water samples. An initial antibiotic […]

Comparison of Dark Matter Proportions Across Types of Spiral Galaxies

doi: 10.22186/jyi.33.1.1-7 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References | PDF Abstract A large obstacle on the path to better understanding the evolution of the Universe is knowing the extent to which “nature” and “nurture” affect structures in our Universe. Recent studies have observed that many galactic properties such as luminosity and morphology are dependent on their environment and in particular, their halos, […]

Is Unpaved Road Dust Near Fairbanks, Alaska a Health Concern? Examination of the Total and Bioaccessible Metal(loid)s

doi:10.22186/jyi.33.1.8-18 Abstract | Introduction | Methods | Results | Discussion | Conclusions |Acknowledgements | References | PDF Abstract Recent studies highlight the health risks associated with toxic metal(loid)s [e.g., arsenic (As), zinc (Zn), and lead (Pb)] in dust from mining operations, urban settings, and rural roads. To have a deleterious health effect, inhaled or ingested metal(loid)s must dissolve under conditions in the lung or gastrointestinal tract. In this study, we […]

Life at the Forefront of Infectious Disease : An Interview with Dr. Andrew Henderson

PDF In his office, tucked away in a sixth floor laboratory in the Evans Biomedical Research Center, Dr. Andrew Henderson shared his non-linear path into a career researching infectious disease. Dr. Henderson is an Associate Professor at the Boston University School of Medicine and Assistant Dean of the Graduate Medical Sciences division. Between these roles, […]
