Elucidating The Relationship Between Water Quality And Antibiotic Resistance Of Rainwater Microbes Across Western Humboldt County, Theo P. Murphy, Eve Wendley, Justice Laskowski, Tyler Paredes

Humboldt Journal of Microbiology

Limited studies have been conducted regarding the fecal contamination and microbial dispersal through rainwater, with no known studies investigating the potential connection between antibiotic resistant microbes and water quality in rainwater. This study seeks to identify the presence of a correlation between water quality and incidence of antibiotic resistance in rainwater microbes. We hypothesize that there will be a correlation between these two variables. We additionally anticipate a high incidence of fecal contamination across rural and urban collection sites alike, with fecal contamination being more prevalent in rural areas than urban locals. To determine water quality, we measured the concentration …

Selective Serotonin Reuptake Inhibitors And Pharmacological Resetting Of The Mind, Ion G. Motofei, David L. Rowland Apr 2024

Selective Serotonin Reuptake Inhibitors And Pharmacological Resetting Of The Mind, Ion G. Motofei, David L. Rowland

Journal of Mind and Medical Sciences

Mental activity is capable of processing analytical data (mathematics, physics, socio-political science, philosophy, etc.) similar to computer software. At the same time, mental activity largely depends on the brain, which works like a hard component of a computer. While the computer stores data on a physical medium, mental activity and data are supported by physiological mechanisms that are constantly operating (both in wakefulness and sleep). For this reason, the lack of brain oxygenation even for short periods of time (5-10 minutes) causes the loss of all data, including the disappearance of the individual's existence as a mental entity. This means …

Killing Cancer: Manipulating Hydrophobic Vanadium Complexes To Improve Anti-Cancer Activity, Levi Ausherman, Debbie C. Crans, Peter A. Lay, Maggi Braasch-Turi

SACAD: Scholarly Activities

Hydrophobic vanadium complexes have recently shown improved anti-cancer activities compared to cisplatin. The hydrophobicity and anti-proliferative activity of [VO(Hshed)(dtb)] ([Hshed= N-(salicylideneaminato)-N’-(2-hydroxyethyl)-1,2-ethanediamine and dtb= 3,5-di(tert-butyl)catechol)]) have inspired the development of a library of hydrophobic vanadium complexes. Increasing the steric bulk of the catechol ligand has been shown to have a direct impact on hydrophobicity and anti-proliferative activities. Currently at Fort Hays State University, the Braasch-Turi group is synthesizing VO(HSHED)(dtb) to build up material to support the chemical analysis and biological assay performed by our collaborators at Colorado State University and the University of Sydney, Australia, respectively.

The goal of this narrative review was to provide a synopsis of pertinent literature on calcium use in obstetrics to explore the potential benefit of calcium carbonate as a simple and low-cost intervention for prevention or treatment of labor dystocia. To answer how calcium and carbonate physiologically contribute to myometrium contractility, we conducted a literature search of English-language peer-reviewed articles, with no year limitation, consisting of the keywords “calcium,” “calcium carbonate,” “calcium gluconate,” “pregnancy,” “hemorrhage,” and variations of “smooth muscle contractility” and …


Associations Between Cannabis, Psychosis, And Schizophrenia In Adolescents, Lauren Moment Sep 2022

Associations Between Cannabis, Psychosis, And Schizophrenia In Adolescents, Lauren Moment

Academic Leadership Journal in Student Research

The effects of cannabis use on the brain, mind, and body have been studied for decades. The developing brain, particularly the adolescent and young adult brain, undergoes critical development that makes it especially susceptible to the effects of cannabis use. Among the adverse effects of cannabis use in adolescence and young adulthood, psychosis and psychotic disorders (e.g., schizophrenia) have been examined. The association of cannabis use with schizophrenia was first elucidated in a Swedish study of army conscripts. Specifically, conscripts reported their cannabis use exposure and were followed longitudinally to assess the emergence of schizophrenia. The authors found that those …

The Benefits Of Astaxanthin To Improve Pain Relief In Patients With Painful Diabetic Neuropathy: An Open-Label, Randomized Controlled Trial, Rizaldy Taslim Pinzon, Mary Rose Angelina Budi Harsana

Pharmaceutical Sciences and Research

Treatment of diabetic neuropathy is still carried out by providing symptomatic therapy, which only improves ± 50% of the total symptoms felt by patients, but does not tackle the underlying causes of the disease. Astaxanthin is a potent antioxidant, anti-inflammatory, and anti-diabetic carotenoid that could be an additional treatment option. We aimed to measure the effectiveness of administering astaxanthin as an additional therapy to improve the impact of pain and discomfort experienced daily by diabetes mellitus patients with painful diabetic neuropathy. We conducted a randomized experimental study with an open label design of 36 patients who had been diagnosed with …

Chemical Composition And Behavioural Responses Of Male And Female Bactrocera Dorsalis To Their Volatile Emissions, Fikira Kimbokota

Journal of Humanities and Social Sciences

Bactrocera dorsalis, (Tephritidae) presented a grave threat to a broad range of fruit and vegetables in the tropics, including Tanzania. Bactrocera dorsalis is among the most destructive tephritid fruit fly, causing devastating loss of fruits especially mango. Insects use olfactory cues to locate hosts, oviposition sites and mating, in which pheromones are believed to be a strong cue used by insect to locate their mates. However, due to their high ability to adapt and occupy different ecological niches into various agroecological zones, there is a need to evaluate pheromonal composition from time to time to improve their control strategies. Therefore, …

Analysis Of The Proposed Tpp-Related Patent Linkage System In Taiwan, Ping-Hsun Chen Jul 2017

Analysis Of The Proposed Tpp-Related Patent Linkage System In Taiwan, Ping-Hsun Chen

Journal of Law and Health

The Trans-Pacific Partnership (TPP) Agreement mandates member states to implement a patent linkage system vested in Article 18.53. To successfully join the TPP Agreement, Taiwan has begun the legislation of a patent linkage system by proposing an amendment for the Pharmaceutical Affairs Act. Article 18.53 requires a member either to adopt a notification mechanism under Paragraph 1 or to stay the issuance of marketing approval under Paragraph 2. But, Taiwan’s proposal includes both measures. Taiwan’s patent linkage system allows a pioneer drug company to register patents claiming (a) a material, (b) a combination or formula, or (c) pharmaceutical use. The …


Structural Dichotomy Of The Mind; The Role Of Sexual Neuromodulators, Ion G. Motofei, David L. Rowland Sep 2016

Structural Dichotomy Of The Mind; The Role Of Sexual Neuromodulators, Ion G. Motofei, David L. Rowland

Journal of Mind and Medical Sciences

The mind (mental function) and sexuality represent two distinct environmental functions, but which are supported within the brain by a common (somatic-autonomic) neurobiological substrate. As a consequence, mental function takes on autonomic characteristics from the sexual-autonomic system (like autonomy, duality), while sexual function takes on features from mental functioning (such as lateralization). In this paper we discuss the lateralized action of two classes of sexual neuromodulators: hormones and pheromones. This process of lateralization is assimilated with the structural dichotomy of the mind.

A relatively similar process but related to informational dichotomy of the mind will be presented in a forthcoming …


Na/K-Atpase Amplification Of Oxidant Stress; A Universal But Unrecognized Clinical Target?, Zijian Xie, Phd, Joseph I. Shapiro, Md Apr 2016

Na/K-Atpase Amplification Of Oxidant Stress; A Universal But Unrecognized Clinical Target?, Zijian Xie, Phd, Joseph I. Shapiro, Md

Marshall Journal of Medicine

The Na/K-ATPase has a signaling function which appears to be separate from its ion pumping function. This signaling function refers to the transduction of conformational changes in the Na/K-ATPase alpha1 subunit into activating Src’s tyrosine kinase activity, triggering a cascade which generates reactive oxygen species (ROS), modulates other signaling pathways, and causes many physiological and pathophysiological effects. We have recently observed that ROS themselves as well as cardiotonic steroids can actually initiate the signal by directly inducing conformational changes in alpha1. It therefore appears that the Na/K-ATPase signal cascade can serve as a feed forward amplification for ROS with circulating …

Marshall Journal of Medicine

Vitamin D is known to play an essential role in calcium homeostasis; however, excessive amounts can have harmful effects. Calcium and vitamin D levels are known to be influenced by drug interactions and pathology ranging from of cancer to cardiovascular disease. Vitamin D supplementation has become widespread, and it is important for clinicians to understand the way that certain conditions and medications interact with vitamin D and calcium homeostasis. The purpose of this review is to outline the benefits and adverse effects of vitamin D and how its levels are affected by certain pathologic and pharmacologic interactions.


Similarities Between Corticosteroids, M. Einhorn Jan 2014

Similarities Between Corticosteroids, M. Einhorn

The Science Journal of the Lander College of Arts and Sciences

Corticosteroids are a class of potent drugs with important physiological effects on the body. Regular use is linked with common and serious side effects. This paper uses studies to analyze the similarities between various corticosteroids. All drugs in this class are molecules that contain the same steroid backbone and are therefore associated with the same cellular receptor. This results in a comparable mechanism and parallel overall effect in the body. Side effects of corticosteroids are analogous as well. Using the knowledge of physiological changes in the body due to corticosteroids will allow healthcare providers to determine the most effective corticosteroid …
