Unequal distribution of wealth is a matter of growing concern in contemporary society, but it is also one with deep roots in the past. Several authors have traced the origins of this inequality by reconstructing historical series and collecting and harmonising data from sources and records with uneven territorial and temporal cover (Milanovic et al. (2011), Alfani (2015) Piketty (2014 and 2020)).
The electrophysiological and behavioral responses of male Agrotis segetum to fluorinated analogs of (Z)-5-decenyl acetate (Z5-10:OAc) were investigated. The single sensillum recordings showed that 4,4-difluoro-(Z)-5-decenyl acetate (4,4-F2), 7,7-difluoro-(Z)-5-decenyl acetate (7,7-F2), 10,10,10-trifluoro-(Z)-5-decenyl acetate (10,10,10-F3) and 7,7,8,8-tetrafluoro-(Z)-5-decenyl acetate (7,7,8,8-F4)
The repeatability of the composition of pheromone emitted by individual female moths (Yponomeuta) was determined by gas Chromatographic analysis. An improved technique for repeated collections of airborne volatiles from the same moth was developed. The procedure did not harm the females and allowed precise quantification of 0.05 ng of pheromone components in 30-min collections. Individual females
Objective: Falls and related injuries are known to be the major health problem leading to disability and mortality among older adults. Identification and management of fall risks aimed to prevent falling is considered to be essential. The aim of this study was to develop a mobile application for screening and management of fall risks based for older adults. Method and materials: First, we determin
The present paper investigates the ongoing validity of the notion of subordination as selection criteria to allocate the labour protections in the contemporary economic framework. The gig economy is deeply affecting the way of working, transforming the employee in a service provider. This phenomenon is partially due to the progressive shift from a firm-based production model towards a market trans
γ-Aminobutyric acid (GABA) increases the rate of 36Cl- efflux from preloaded rat hippocampal slices in a dose-dependent manner (EC50: 400 μM). This action has the pharmacological specificity expected of activation of GABA receptor in that it is mimicked by the agonists muscimol and 3-aminopropanesulfonic acid, and blocked by the antagonists bicuculline and picrotoxinin. GABA uptake inhibitors, nip
One of the challenges in wooden constructions is to be able to achieve a good acoustic insulation especially in the low frequency range. The prediction of acoustic performance of wooden buildings before erection becomes important and reliable predictive tools are in great need. To that end, the first question that arises is how to accurately model the excitation source which generates the structur
CEREBRAL ISCHEMIA ASSOCIATED with subarachnoid hemorrhage may have severe consequences for neuronal functioning. The excitatory amino acid neurotransmitters glutamate and aspartate have been shown to he of particular importance for ischemia and ischemic neuronal damage. For seven patients who underwent early surgery for ruptured intracranial aneurysms, intracerebral microdialysis of glutamate and
Ischemic brain insults are accompanied by several metabolic alterations. In the present review, the adverse reactions, which might be important for the outcome of these insults, are those related to phospholipid and polyunsaturated fatty acid metabolism triggered by the disturbed calcium ion homeostasis in combination with energy depletion following ischemia. These conditions lead to an activation
Pathogens rely on a complex virulence gene repertoire to successfully attack their hosts. We were therefore surprised to find that a single fimbrial gene reconstitution can return the virulence-attenuated commensal strain Escherichia coli 83972 to virulence, defined by a disease phenotype in human hosts. E. coli 83972pap stably reprogrammed host gene expression, by activating an acute pyelonephrit

Objectives: Moderate physical activity gains survival. There are, however, several variables that may affect this relationship. In this study, the relationship between moderate physical activity and longevity was investigated, taking into account age, gender, smoking habits, cohabitation status, body mass index, leg strength and balance, education level and cognitive function. Method: A sample of
Significantresearch efforts are currently directed towards the synthesis and studies of durable anion exchange membranes (AEMs) with the aim to develop alkaline fuel cells and electrolyzers able to operate efficiently without platinum-groupmetal catalysts [1]. The grand challenge is to identify and synthesize polymeric AEM materials possessingthe necessary chemical and therma
The objective was to examine relationships between meat and other food items which have been associated with higher risk of cancer in the colon and prostate in some epidemiological studies. The study was conducted as a population-based cohort study comprising 11648 subjects (4816 male and 6742 female) born between 1926 and 1945 and living in the city of Malmo, Sweden. Data on mean daily intake of
Transforming growth factor-α (TGF-α) exerts several effects on target cells, such as neovascularization promotion and mitogenic signalling. Using immunoelectron microscopy, we show that monocytes and neutrophils, store TGF- α in cytoplasmic granules. In monocytes, TGF-α did not colocalize with components of peroxidase-positive granules or with albumin of secretory vesicles. Furthermore, no colocal
Hemolysins are cytolytic proteins which have been extensively characterized at the molecular level, however, their in vivo functions remain unclear. This study analyzed the association of hemolysin production with the inflammatory response in patients with urinary tract infection (UTI). Infants and children with their first episode of UTI (n = 644) were followed prospectively. The body temperature
The influence of different reaction systems on α-chymotrypsin-catalyzed synthesis of eledoisin and LH-RH peptides from (7+4) and (5+5) fragments was investigated. The peptide yield was determined in the following systems: buffered aqueous media, frozen solutions, organic media, and cosolvent mixtures. The experimental set up was tailored to allow the screening of an array of conditions with minimu
