Of Course, Humans Are Not Unique!, Bernard Wallner Jan 2019

Of Course, Humans Are Not Unique!, Bernard Wallner

Animal Sentience

This commentary focuses on the question of the uniqueness of humans in comparison to other species and on the false assumption that single arguments support logical conclusions. Comparative analysis of genetic data in humans and nonhuman primates regarding the dopaminergic system of the subcortical mesolimbic reward system highlights homologous traits shared and modified by the process of evolution. Such an analytical approach is more relevant than claims of uniqueness.


Killi-Data News (Winter), Tyrone Genade Mar 2018

Killi-Data News (Winter), Tyrone Genade

Killifish Research Review

Valued readers, it is with a heavy heart that I inform you that this is the last issue of Killi-Data News. The good news is that we will be back as Killifish Research Review. The dissolution of Killi-Data International created a prob- lem: how can the newsletter of a defunct organization live on without that organization? But other additional problems were building in the background. The first issue numbered 15 pages. The previous issue was 28 pages. The number of killifish related papers is increasing while time on our end (the editorial team) is running out. It takes a lot ...

Killi-Data News (Fall), Tyrone Genade

Killifish Research Review

Many interesting papers have been published over the last three months. The large volume of papers coupled with the start of the new college semester (and the workload it brings) delayed this issue of Killi-Data News. But better late than never—or so I hope! In this issue Richard van der Laan provides an insightful review of the recent Aphanius papers as to their taxonomic implications and questions. The systematic issues he raises show the importance of the Molecular project: we need to get more samples of the various cyprinodontiforme families to resolve unsettled systematic and taxonomic issues. In the ...

Killi-Data News (Summer), Tyrone Genade

Killifish Research Review

Over the last three months several interesting and exciting pa- pers have been published. By now most of you have heard the Nothobranchius fish poo news emanating from the Valenzano lab. That paper is reviewed and certainly has repercussions for the health of our captive fish. Polaçik et al have published interesting data with ramifications as to how we breed and incubate annual killifish. The big news in this issue is the paper from the Reznick lab which Jean Huber reviews. The contents of that paper goes to the heart of the question of just what a killifish is. The ...

Killi-Data News (Spring), Tyrone Genade

Killifish Research Review

This is the start of Killi-Data News’ second year. In this first issue of the year we have the usual review of research pub- lications as well as input from Martin Reichard on his lab’s Nothobranchius research. Martin is responding to my reviews of his lab’s work in the previous edition. I am serious about making sure the content in this newsletter is reliable but I erred in the previous edition and Martin has written extensively to correct my mistake in the section “Erratum”. This reply is welcomed and owed to readers. I must confess that I don ...

Killi-Data News (Winter), Tyrone Genade

Killifish Research Review

This is the fourth edition, and concluding issue of the first volume, of Killi-Data News and I am happy that it has been well received by readers. At 25 pages this issue is a bit thin- ner than the last but this is because we agreed to make the cut-off for submissions the 1 st of December so we could get this edition out by the New Year. This is an exciting edition full of new species descrip- tions and analyses that will keep taxonomists busy for years to come. Costa has given us two molecular phylogenies on Melanorivulus as ...

Bioaccumulation Of Metallic Trace Elements And Antioxidant Enzyme Activities In Apfelbeckia Insculpta (L. Koch, 1867) (Diplopoda: Callipodida) From The Cave Hadži-Prodanova Pećina (Serbia), Jelena Vranković, Slavica Borković-Mitić, Bojan Ilić, Milanka Radulović, Slaviša Milošević, Slobodan Makarov, Bojan Mitić Feb 2017

Bioaccumulation Of Metallic Trace Elements And Antioxidant Enzyme Activities In Apfelbeckia Insculpta (L. Koch, 1867) (Diplopoda: Callipodida) From The Cave Hadži-Prodanova Pećina (Serbia), Jelena Vranković, Slavica Borković-Mitić, Bojan Ilić, Milanka Radulović, Slaviša Milošević, Slobodan Makarov, Bojan Mitić

International Journal of Speleology

The concentration of 10 metallic trace elements or MTE (Cu, Fe, Zn, Mn, As, Hg, Pb, Cd, Ni, and Cr) was measured in specimens of the troglophilic millipede Apfelbeckia insculpta (L. Koch, 1867) and sediment of the cave Hadži-Prodanova Pećina in western Serbia. Some MTE, like Fe and Mn, displayed much higher concentrations compared to other elements, both in the sediment and in the body of A. insculpta. On the other hand, estimation of the bioaccumulation factor (BAF) in both males and females of A. insculpta showed values greater than 1 for xenobiotic elements compared to those that are essential ...


The Effects Of Adaptogens On The Physical And Psychological Symptoms Of Chronic Stress, Tosin O. Ajala Jan 2017

The Effects Of Adaptogens On The Physical And Psychological Symptoms Of Chronic Stress, Tosin O. Ajala

DISCOVERY: Georgia State Honors College Undergraduate Research Journal

Stress is a state of disharmony or threatened homeostasis. The maintenance of homeostasis in stages of internal or external challenges, called stressors, requires constant adjustments of hormonal, behavioral, and autonomic functions. The nuances of life may bring about unwanted stress to the human body. Some of the top causes of stress in America include work, finances, relationships, and health. There are numerous physical and psychological symptoms associated with long-term “chronic” stress, which include chronic fatigue, frustration, irritability, insomnia, frequent headaches, chest and back pain, weakness, and weight gain or weight loss. These symptoms of chronic stress are associated with depression ...


Dietary Weight Loss Advice In Us Health Magazines And Its Relation To Ancestral Diet, Risa J. Stein, Marium A. Choudhry, Thomas J. Murray Jr. Jul 2016

Dietary Weight Loss Advice In Us Health Magazines And Its Relation To Ancestral Diet, Risa J. Stein, Marium A. Choudhry, Thomas J. Murray Jr.

Journal of Evolution and Health

As rates of overweight and obesity have risen in the US, the public has sought effective strategies for weight loss through dietary modification. A proliferation of processed foods and changing governmental nutrition guidelines have both impacted dietary intake patterns. While physicians are considered respectable sources of weight-loss information, increasingly the public has turned to the media, particularly magazines, for weight loss advice. This study investigated the dietary recommendations found in the five leading US health-related magazines and compared those recommendations to ancestral diets. With a couple notable exceptions, leading health magazines present consistent recommendations for dietary modifications to promote weight ...


The Effect Of Maternal Aldosterone Levels On The Expression Of 11b-Hsd Isoenzymes In Normal And Hypertensive Rat Placentae, Nicole Jorissen Aug 2014

The Effect Of Maternal Aldosterone Levels On The Expression Of 11b-Hsd Isoenzymes In Normal And Hypertensive Rat Placentae, Nicole Jorissen

Journal of Undergraduate Research at Minnesota State University, Mankato

In this project, we developed a Western blotting procedure to semi-quantitate levels of 11β-HSD1 and 11β-HSD2 in whole cell extracts. Then, we applied this technique to analyze the effect of reduced maternal aldosterone levels on the expression of 11β-HSD1 and 11β-HSD2 isoenzymes in the placental tissue in both normal and hypertensive rats. These enzymes control levels of glucocorticoids which compete for aldosterone’s mineralocorticoid receptor. Overstimulation of this receptor results in hypertension. If aldosterone levels decrease, levels of the enzymes controlling active glucocorticoid concentrations might change to compensate for the lowered aldosterone levels. Decreased placental 11β-HSD2 expression could affect hypertension ...


From Heart Beats To Health Recipes: The Role Of Fractal Physiology In The Ancestral Health Movement, Aaron P. Blaisdell, Brent Pottenger, John S. Torday Dec 2013

From Heart Beats To Health Recipes: The Role Of Fractal Physiology In The Ancestral Health Movement, Aaron P. Blaisdell, Brent Pottenger, John S. Torday

Journal of Evolution and Health

The human body—an amazing biological system that scales up fractally from its cellular building blocks—exhibits an incredible ability to self heal. Why then, are chronic diseases and degeneration on the rise in the population? Why are we sicker, more obese, and more depressed and stressed than ever before in human history? Why can’t we heal? The answers to these questions may lie in our ancestry, and modern departure from the human ecological niche. The ability to heal requires proper spatio-temporal inputs—nutrition, sleep, stress, activity, and socialization—in order for cellular signaling to occur properly across semi-permeable ...

Calcium And Cell Volume Regulation In Alligator Mississippiensis Erythrocytes, Alina Spivak Apr 2008

Calcium And Cell Volume Regulation In Alligator Mississippiensis Erythrocytes, Alina Spivak

Eukaryon

Maintenance of proper cell volume is critical for cell survival and proliferation; consequently, animal cells routinely control their volume to maintain homeostasis. For instance, biological processes such as the response to ischemia (insufficient blood flow), lymphocyte activation, and apoptosis (programmed cell death) are associated with changes in cell volume. It has been well established that osmotic swelling associated with a hypotonic medium is followed by a regulated volume decrease (RVD) resulting from the efflux of specific solutes. However, the signaling mechanisms of RVD are ill defined. The effect of calcium on RVD was studied because this ion is a common ...
