Diversity in the Bacterial Genus Dickeya Grouping Plant Pathogens and Waterways Isolates

Received: 25 July 2019;  Published: 26 November 2019;  doi: 10.21926/obm.genet.1904098

Abstract

Background: Genus Dickeya comprises aggressive soft rot plant pathogens with wide geographic distribution and host ranges. Ten Dickeya species were characterized. Seven of them (Dickeya chrysanthemi, D. dadantii, D. dianthicola, D. fangzhongdai, D. solani, D. paradisiaca, and D. zeae) group causative agents of maceration-associated diseases that impact a wide variety of crops or ornamentals as well as isolates from fresh water. The other three species (D. aquatica, D. lacustris, D. undicola) were recently isolated [...]

Does Dementia Increase the Risk of Dental Decay?

Received: 09 January 2019;  Published: 21 March 2019;  doi: 10.21926/obm.geriatr.1901040

Abstract

The amount of patients who suffer with dementia is set to rise with an ageing population. As well as living longer, patients will be retaining their natural teeth into their later life and will be less reliant on dentures. From both the current evidence available in the literature, and anecdotally from clinicians experienced in treating patients with dementia, it can be concluded that on balance, patients with dementia appear to be at a greater risk from dental caries (dental decay). However, more research in this [...]

Autonomous Hydrogen Production for Proton Exchange Membrane Fuel Cells PEMFC

Received: 04 March 2020;  Published: 28 April 2020;  doi: 10.21926/jept.2002004

Abstract

This paper focuses on hydrogen production for green mobility applications (other applications are currently under investigation). Firstly, a brief state of the art of hydrogen generation by hydrolysis with magnesium is shown. The hydrolysis performance of Magnesium powder ball–milled along with different additives (graphite and transition metals TM = Ni, Fe, and Al) is taken for comparison. The best performance was observed with Mg–10 wt.% g mixtures (95% of theoretical hydrogen generation yield in about 3 min). An [...]

Consumption of a Recommended Serving of Wheat Bran Cereals Significantly Increases Human Faecal Butyrate Levels in Healthy Volunteers and Reduces Markers of Inflammation Ex Vivo

Received: 08 October 2021;  Published: 17 December 2021;  doi: 10.21926/rpn.2104002

Abstract

Wheat bran cereals are an important source of dietary fibre. The aim of the study was to investigate if a high intake (120 g) of fibre rich breakfast cereal (which delivers the UK Government guidelines for fibre intake in one serving but is three-fold higher than the manufacturers recommended serving) has additional potential health benefits compared to the recommended serving (40 g, containing 11 g of dietary fibre). To assess this, the study determined the short chain fatty acid (SCFA) profiles in human faecal, u [...]

Unusual Ways to Lose a Y Chromosome and Survive with Changed Autosomes: a Story of Mole Voles Ellobius (Mammalia, Rodentia)

Received: 16 May 2018;  Published: 22 July 2018;  doi: 10.21926/obm.genet.1803023

Abstract

Species of mole voles Ellobius demonstrate a broad variation in sex chromosomes and autosomes, which is unique among mammals. In four species, a Y chromosome was lost, and X0 or XX sex chromosomes in both sexes were obtained. The key testis-determining Sry (Sex-determining Region on Y) gene is absent in these species, and the regulation of its target, the Sox9 (SRY -box 9) gene, is questionable due to deletion in the key enhancer. In a single species, E. fuscocapillus, with routine XX-XY, the same deletion is prese [...]

A Neurotransmitter Approach to the Trolley Problem

Received: 25 February 2019;  Published: 28 June 2019;  doi: 10.21926/obm.neurobiol.1902030

Abstract

Is it ethically permissible to sacrifice the life of one human being in order to save the lives of five others? This question forms the basis of the famous thought experiment called “the trolley problem.” Surveys have found that 90 percent of people agree it is permissible when the victim to be sacrificed is described as off in the distance, whereas the opposite result occurs if the victim is described as up close. No consistent ethical principle has been identified that account for these results. In this paper we [...]

Genetic and Epigenetic Regulation of Telomere Length: Current Findings, Methodological Limitations and Possibilities for Future Studies

Received: 29 October 2018;  Published: 19 December 2018;  doi: 10.21926/obm.genet.1804055

Abstract

Telomeres are TTAGGG repeats located at the end of chromosomes that maintain DNA stability. Telomere length (TL) has been widely implicated as a marker of biological age, and is associated with several human diseases, including depression, cardiovascular disease and cancer. Twin studies and cohort studies estimate heritability of TL between 78-82%. Moreover, several genomic loci which influence TL have been identified. Despite the success of genetic studies in furthering our understanding of telomere biology, ident [...]

Durability of Alkali-Activated Materials Made with a High-Calcium, Basic Slag

Received: 09 June 2021;  Published: 13 October 2021;  doi: 10.21926/rpm.2104041

Abstract

Alkali activated (AA) materials have been investigated for decades as an alternative to Portland cement (PC) products. Most consist of a silicate waste activated with alkalis, which leads to lower green-house gas emissions and a substantial drop in the use of unrenewable material resources. This paper studies the durability of AA materials made with a ground granulated blast furnace slag (GGBS) from Dublin, activated with sodium hydroxide (NaOH), and sodium silicate (Na2SiO3), both combined and separately, and cure [...]

Genomic Analysis for Citrus Disease Detection

Received: 26 October 2020;  Published: 18 February 2021;  doi: 10.21926/obm.genet.2101124

Abstract

Citrus is an important group of globally produced fruit crops, holding great economic, cultural, and health value. Belonging to the Rutacaeae family, the genus Citrus includes some of the most iconic and widely appreciated variants of fruits such as the orange, lemon, lime, grapefruit, and tangerine. The spread of various diseases threatens the worldwide production of citrus fruit crops. Diseases such as Asiatic citrus canker, citrus tristeza virus, citrus leprosis, and especially citrus greening disease (also know [...]
