Fungal taxonomy is the branch of mycology by which we classify and group fungi based on similarities or differences. Historically, this was done by morphologic characteristics and other phenotypic traits. However, with the advent of the molecular age in mycology, phylogenetic analysis based on DNA sequences has replaced these classic means for grouping related species. This, along with the abandonment of the dual nomenclature system, has led to a marked increase in the number of new species and reclassification of known species...

Long-term exposure of concrete to nuclear reactor environments may enhance the ageing phenomena. An investigation concerning a possible deleterious alkali-silica reaction (ASR) in concrete containing high-density aggregates is presented in this paper. The scope of this investigation was limited to heavy aggregates that could be used for the construction of the first Polish nuclear power plant (NPP). Five different high-density aggregates were selected and tested: three barites, magnetite, and hematite. Mineralogical analysis was conducted using thin section microscopic observation in transmitted light...

Lasiodiplodia theobromae is a known plant pathogen in tropical and subtropical areas. Few cases have been reported in humans (usually keratitis and endophthalmitis) with only two cases of fungal sinusitis in immunocompromised and immunocompetent patients published to date. We report a case of invasive sinusitis secondary to L. theobromae in an allogeneic hematopoietic cell transplant recipient successfully treated with surgical debridement and triazole antifungals with a review of available literature.

PURPOSE: Retinol binding protein 4 (RBP4) has recently been identified as an adipokine possibly involved in the development of impaired glucose metabolism. We aimed to test serum RBP4 in healthy non-obese individuals and in patients with well-characterized phenotype: obesity without confounding effects of diabetes, metabolic syndrome or dyslipidaemia. Additionally, we examined whether serum RBP4 is associated with anthropometric parameters, insulin resistance and blood lipid parameters...

Diabetics in mid-life carry a 1.5 times higher risk of developing Alzheimer's disease than those diagnosed with diabetes (T2D) later in life [1]. Recent research points to accelerated cognitive decline within a range of 20%-50% for middle-aged diabetics as compared to non-diabetic populations [2,3]. Metabolic syndrome (MetS), a type 2 diabetes (T2D) precursor, is also linked to MCI and AD pathologies via hypo-metabolic brain circuitry that inhibits glucose metabolism and attenuates cognitive function [4]. Dysregulation of intracellular and extracellular signaling as mediated by the mTOR and AMPK pathways is the result...

A vast amount of research has been done on the APOE4 genetic marker for Alzheimer's disease (AD), but its connection to metabolic processes associated with peripheral insulin resistance and cerebral glucose metabolism is still relatively unknown. The APOE4 allele is the strongest genetic risk factor for developing late-onset Alzheimer's disease, particularly in individuals who have inherited two copies of the gene (Zhao et al., 2017). In this case study, a 38 year old male with metabolic syndrome (MetS), the APOE4 gene, early stage memory problems and a family history of Alzheimer's Disease (AD) was placed on a ketogenic diet combined with high intensity interval training (HIIT) for 10 weeks...

Alzheimer's disease (AD) deaths have increased by 89% since 2000. This alarming trajectory of neurological disease highlights the failure of current best practice. Deteriorating brain fuel supply is the nemesis of intact neurological health. Cerebral hypo-metabolism associated with AD occurs years before onset. Both the ketogenic diet and calorie restriction (fasting) lead to a compensatory rise in ketones to improve energy deficits in the brain derived from cerebral insulin resistance. Two forms of ketone bodies, β-hydroxybutyrate and acetoacetate, fuel the brain during starvation, fasting and strenuous exercise...

It has been proposed that regular cold swimming is associated with health benefits. However, the effect of cold adaptation on particular cardiovascular risk factors, within a single swimming season, remains unknown. Our aim was to evaluate the impact of cold water swimming on the seasonal changes in lipid profile and on apolipoprotein and homocysteine concentration in 34 cold water swimmers (CWS) aged 48 - 68 years. Blood samples were collected at the beginning (October), the middle (January), and the end (April) of the swimming season...

The hydrogen-bonded self-associates of dimethylphosphinic (1), diphenylphosphoric (2), phenylphosphinic (3), and bis(2,4,4-trimethylpentyl)phosphinic (4) acids have been studied by using liquid-state NMR down to 100 K in a low-freezing polar solvent, CDF3 /CDClF2 . The H/D isotope effects on 1 H NMR chemical shifts caused by partial deuteration of hydroxyl groups unambiguously reveal the stoichiometry of the self-associates and the cooperativity of their hydrogen bonds. In all cases, cyclic trimers are the dominant form, while cyclic dimers are present as a minor form for 1 and 2...

OBJECTIVES: Prolonged suppression of gastric acid secretion by proton pump inhibitors (PPIs) may alter the bacterial microbiota of the upper gastrointestinal tract and lead to small bowel bacterial overgrowth (SBBO). Published reports have shown conflicting results on the association between PPI therapy and risk of SBBO development. We evaluated whether long-term PPI treatment is associated with presence of SBBO as determined by breath hydrogen (H2 ) and methane (CH4 ) excretion. We also assessed the differences in H2 /CH4 excretion patterns in patients taking PPI compared with those not taking the medication and searched for the potential predictors of a positive breath test result...

Recent studies indicate disruptions to the circadian system in brain injury and neurodegeneration. The results, however, are often not consistent and limited by measurement of only one circadian marker and by infrequent sampling rates. In this study, we examined diurnal rhythmicity in different stages of Huntington (HD) disease and in patients with acute moderate ischemic stroke (AIS) outside the retinohypothalamic pathway by evaluating serum concentrations of melatonin and cortisol at twelve timepoints. All study participants were subjected to the same study protocol of 12-hour light/dark cycle and controlled room conditions...

Invasive fungal infections are an important cause of morbidity and mortality affecting primarily immunocompromised patients. While fungal identification to the species level is critical to providing appropriate therapy, it can be slow and laborious and often relies on subjective morphological criteria. The use of matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry has the potential to speed up and improve the accuracy of identification. In this multicenter study, we evaluated the accuracy of the Vitek MS v3...

The present paper is a review of current knowledge concerning the most appropriate strategy in the conservative therapy of obese children and adolescents. It presents an account of the combined mode of therapy consisting of behavioral and dietary counseling with appropriate physical activity (also using the support of modern media and devices). The rise in obesity is usually a long-lasting process involving genetic predispositions but also environmental factors which can be modified. The treatment of obesity should be focused on these modified factors and be a lifelong treatment, not merely a short period of exercise or a diet program...

Type II Diabetes affects 400 million people worldwide (IDF, 2013). The pathology is paradoxical: internal starvation activated by overfeeding. Hyperinsulinemic impairments of glucose homeostasis are treated with anti-hyperglycemics exacerbating cell starvation, inducing hypoglycemia and raising respiratory quotient. Reductions in hyperglycemia are achieved at the expense of glucose dependency and metabolic inflexibility (Gibas & Gibas, 2017). The brain is not immune from these cycles of starvation. The bioenergetic model characterizes propagation of late-onset, sporadic Alzheimer's disease as loss of molecular fidelity and compromised energy originating in brain networks with highest metabolic demand...

The maintenance of copper homeostasis is critical for all cells. As learned from mice with disturbed copper metabolism, this trace element is also important for spermatogenesis. The experiments conducted in yeasts have demonstrated that appropriate copper level must be preserved to enable meiosis progression; however, increased copper level is toxic for cells. This study aims to analyze the expression profile of Atp7a and Atp7b and other genes encoding copper-related proteins during spermatogenesis in mice...
