A new twist on the graduate student journal club: Using a topic‐centered approach to promote student engagement
(2020-02)Journal clubs are widely used as an educational tool in graduate life science programs. In journal clubs, students are assigned to read specific journal articles to achieve a broad knowledge in their field of study and to ... -
Contribution of wild foods to diet, food security, and cultural values amidst climate change
(2019-11)Wild foods are recognized to contribute to diet and food security through enhancing the availability of local, diverse, and nonmarket food sources. We investigated the contribution of wild foods to diet, food security, and ... -
Janthinobacterium CG23_2: comparative genome analysis reveals enhanced environmental sensing and transcriptional regulation for adaptation to life in an Antarctic supraglacial stream
(2019-10)As many bacteria detected in Antarctic environments are neither true psychrophiles nor endemic species, their proliferation in spite of environmental extremes gives rise to genome adaptations. Janthinobacterium sp. CG23_2 ... -
DropSOAC: Stabilizing Microfluidic Drops for Time-Lapse Quantification of Single-Cell Bacterial Physiology
(2019-09)The physiological heterogeneity of cells within a microbial population imparts resilience to stresses such as antimicrobial treatments and nutrient limitation. This resilience is partially due to a subpopulation of cells ... -
Type I-F CRISPR-Cas provides protection from DNA, but not RNA phages
(2019-10)The type I-F CRISPR–Cas system from Pseudomonas aeruginosa (PA14) provides sequence-specific elimination of invading DNA1,2. Recently, a paper published in Cell Research reported that this system targets mRNA through a ... -
Long-Term Flow through Human Intestinal Organoids with the Gut Organoid Flow Chip (GOFlowChip)
(2019-09)Human intestinal organoids (HIOs) are millimeter-scale models of the human intestinal epithelium and hold tremendous potential for advancing fundamental and applied biomedical research. HIOs resemble the native gut in that ... -
Protective Effects of a New C-Jun N-terminal Kinase Inhibitor in the Model of Global Cerebral Ischemia in Rats
(2019-05-19)c-Jun N-terminal kinase (JNK) is activated by various brain insults and is implicated in neuronal injury triggered by reperfusion-induced oxidative stress. Some JNK inhibitors demonstrated neuroprotective potential in ... -
Neutrophil Immunomodulatory Activity of Natural Organosulfur Compounds
(2019-05-19)Organosulfur compounds are bioactive components of garlic essential oil (EO), mustard oil, Ferula EOs, asafoetida, and other plant and food extracts. Traditionally, garlic (Allium sativum) is used to boost the immune system; ... -
Efficacy and Safety of Immuno-Magnetically Sorted Smooth Muscle Progenitor Cells Derived from Human-Induced Pluripotent Stem Cells for Restoring Urethral Sphincter Function
(2017-04)Human-induced pluripotent stem cells (hiPSCs)-based cell therapy holds promise for treating stress urinary incontinence (SUI). However, safety concerns, especially tumorgenic potential of residual undifferentiated cells ... -
Prioritizing surveillance of Nipah virus in India
(2019-06)The 2018 outbreak of Nipah virus in Kerala, India, highlights the need for global surveillance of henipaviruses in bats, which are the reservoir hosts for this and other viruses. Nipah virus, an emerging paramyxovirus in ... -
Synthetic secoisolariciresinol diglucoside (LGM2605) inhibits Libby amphibole fiber-induced acute inflammation in mice
(2019-07)Background Exposure to the Libby amphibole (LA) asbestos-like fibers found in Libby, Montana, is associated with inflammatory responses in mice and humans, and an increased risk of developing mesothelioma, asbestosis, ... -
Characterization of synovial fluid metabolomic phenotypes of cartilage morphological changes associated with osteoarthritis
(2019-08)"Objective Osteoarthritis (OA) is a multifactorial disease with etiological heterogeneity. The objective of this study was to classify OA subgroups by generating metabolomic phenotypes from human synovial fluid. ... -
Geobiological feedbacks, oxygen, and the evolution of nitrogenase
(2019-02)Biological nitrogen fixation via the activity of nitrogenase is one of the most important biological innovations, allowing for an increase in global productivity that eventually permitted the emergence of higher forms of ... -
TrxR1, Gsr, and oxidative stress determine hepatocellular carcinoma malignancy
(2019-06)Thioredoxin reductase-1 (TrxR1)-, glutathione reductase (Gsr)-, and Nrf2 transcription factor-driven antioxidant systems form an integrated network that combats potentially carcinogenic oxidative damage yet also protects ... -
Physiological adaptations to serpentinization in the Samail Ophiolite, Oman
(2019-03)Hydration of ultramafic rock during the geologic process of serpentinization can generate reduced substrates that microorganisms may use to fuel their carbon and energy metabolisms. However, serpentinizing environments ... -
A Novel Gastric Spheroid Co-culture Model Reveals Chemokine-Dependent Recruitment of Human Dendritic Cells to the Gastric Epithelium
(2019-03)Background & Aims Gastric dendritic cells (DCs) control the adaptive response to infection with Helicobacter pylori, a major risk factor for peptic ulcer disease and gastric cancer. We hypothesize that DC interactions ... -
A review of the mechanisms of mineral-based metabolism in early Earth analog rock-hosted hydrothermal ecosystems
(2019-02)Prior to the advent of oxygenic photosynthesis similar to 2.8-3.2Ga, life was dependent on chemical energy captured from oxidation-reduction reactions involving minerals or substrates generated through interaction of water ... -
A novel multifunctional oligonucleotide microarray for Toxoplasma gondii
(2010-10)Background Microarrays are invaluable tools for genome interrogation, SNP detection, and expression analysis, among other applications. Such broad capabilities would be of value to many pathogen research communities, ... -
Epidemic Clostridioides difficile Ribotype 027 Lineages: Comparisons of Texas Versus Worldwide Strains
(2019-02)Background The epidemic Clostridioides difficile ribotype 027 strain resulted from the dissemination of 2 separate fluoroquinolone-resistant lineages: FQR1 and FQR2. Both lineages were reported to originate in North ... -
Mixing of meteoric and geothermal fluids supports hyperdiverse chemosynthetic hydrothermal communities
(2019-02)Little is known of how mixing of meteoric and geothermal fluids supports biodiversity in non-photosynthetic ecosystems. Here, we use metagenomic sequencing to investigate a chemosynthetic microbial community in a hot spring ...
