Journal of Marine Science and Technology–Taiwan

In recent years, chub mackerel (Scomber japonicus) and spotted mackerel (Scomber australasicus) have started migrating to the coastal areas off Iwate Prefecture earlier than they did previously, resulting in a geographic overlap between hatchery-bred juvenile chum salmon (Oncorhynchus keta) released at sea and the occurrence of predatory mackerel. To clarify whether the mackerels prey on the juvenile chum salmon, we captured adult mackerels by angling during the period when these species overlap in Miyako Bay, Iwate Prefecture. After capture, the stomach contents of the mackerel were examined using a combination of visual examinations and DNA metabarcoding analysis. As a result, …

Feminist Pedagogy In Stem: The Intersection Of Stem Pedagogy And Feminist Theory, Lesley Ann Giddings, Candice Price

Chemistry: Faculty Publications

Science, technology, engineering, and mathematics (STEM) education aims to cultivate the capacity for innovation and real-world problem-solving (Marrero et al., 2014). However, STEM pedagogy has not historically aligned with this goal, often failing to teach students the necessary skills and mindset for creative problem-solving (Stehle & Peters-Burton, 2019). Traditional STEM pedagogical methods, such as rote and lecture-based learning, are based on the teacher being the dominant source of knowledge and students being the passive receivers (Achuonye, 2015; Khalaf & Mohammed Zin, 2018). These methods lack student support, collaboration, active learning, and real-world contexts (Gasiewski et al., 2012). Furthermore, the exclusion …

Investigating Ru(Ii) Anticancer Agents With Non-Canonical Mechanisms Of Action, Richard Joseph Mitchell Jan 2023

Investigating Ru(Ii) Anticancer Agents With Non-Canonical Mechanisms Of Action, Richard Joseph Mitchell

Theses and Dissertations--Chemistry

Platinum(Pt)-based agents are used in approximately 50% of all cancers that are treated with chemotherapy. Unfortunately, the dose-limiting toxicity of these agents remains problematic for patients undergoing treatment. Additionally, Pt(II) therapeutics suffer from transporter-dependent uptake, limited chemical functionalization, and high susceptibility to inactivation by free thiols within the cytosol. Developing small molecules with non-canonical mechanisms of action is one strategy that can be employed to circumvent these limitations. Utilization of coordination complexes with ruthenium(Ru) metal centers is one attractive strategy. Ru(II) compounds are often octahedral, facilitating greater accessibility for chemical diversity; Ru(II) complexes use passive transport and transferrin-mediated transport for …

Faculty, Staff and Student Publications

Chromatin remodeling proteins contribute to DNA replication, transcription, repair, and recombination. The chromodomain helicase DNA-binding (CHD) family of remodelers plays crucial roles in embryonic development, hematopoiesis, and neurogenesis. As the founding member, CHD1 is capable of assembling nucleosomes, remodeling chromatin structure, and regulating gene transcription. Dysregulation of CHD1 at genetic, epigenetic, and post-translational levels is common in malignancies and other human diseases. Through interacting with different genetic alterations, CHD1 possesses the capabilities to exert oncogenic or tumor-suppressive functions in context-dependent manners. In this Review, we summarize the biochemical properties and dysregulation of CHD1 in cancer cells, and then discuss CHD1's …

Articles

Trichomonas vaginalis is responsible for 156 million new cases per year worldwide. When present asymptomatically, the parasite can lead to serious complications, such as development of cervical and prostate cancer. As infection increases the acquisition and transmission of HIV, the control of trichomoniasis represents an important niche for the discovery and development of new antiparasitic molecules. This urogenital parasite synthesizes several molecules that allow the establishment and pathogenesis of infection. Among them, peptidases occupy key roles as virulence factors, and the inhibition of these enzymes has become an important mechanism for modulating pathogenesis. Based on these premises, our group recently …

Publications and Research

The family of ∼60 clustered protocadherins (Pcdhs) are cell adhesion molecules encoded by a genomic locus that regulates expression of distinct combinations of isoforms in individual neurons resulting in what is thought to be a neural surface “barcode” which mediates same-cell interactions of dendrites, as well as interactions with other cells in the environment. Pcdh mediated same-cell dendrite interactions were shown to result in avoidance while interactions between different cells through Pcdhs, such as between neurons and astrocytes, appear to be stable. The cell biological mechanism of the consequences of Pcdh based adhesion is not well understood although various signaling …
