Horses have been valued for their diversity of coat colour since prehistoric times; this is especially the case since their domestication in the Caspian steppe in ∼3,500 BC. Although we can assume that human preferences were not constant, we have only anecdotal information about how domestic horses were influenced by humans. Our results from genotype analyses show a significant increase in spotted
It is estimated that 3-6% of all vasectomised men request vasectomy reversal for different reasons. Microsurgical vasovasostomy is the gold standard technique of vasectomy reversal. However, the microsurgical technique is time-consuming and challenging to most urological surgeons. Therefore, alternative methods of vasal anastomosis have been studied including robotic-assisted vasovasostomy. This r
Testicular biopsy was considered the cornerstone of male infertility diagnosis for many years in men with unexplained infertility and azoospermia. Recent guidelines for male infertility have limited the indications for a diagnostic testicular biopsy to the confirmation of obstructive azoospermia in men with normal size testes and normal reproductive hormones. Nowadays, testicular biopsies are main
Animals living in harsh environments, where temperatures are hot and rainfall is unpredictable, are more likely to breed in cooperative groups. As a result, harsh environmental conditions have been accepted as a key factor explaining the evolution of cooperation. However, this is based on evidence that has not investigated the order of evolutionary events, so the inferred causality could be incorr
Effect of loading rate on cleavage failure probability for ferritic/martensitic steels using Weibull stress analysis is studied. Calibration of Weibull slope for two grades of fusion reactor blanket steels namely, Indian Reduced Activation Ferritic/Martensitic Steel referred as In-RAFMS, F 82H and a non fusion grade modified 9Cr-1Mo steel (P91) are performed for the first time. The calibrated valu
The polynuclear compounds containing anisotropic metal ions often exhibit efficient barriers for blocking of magnetization at fairly arbitrary geometries. However, at variance with mononuclear complexes, which usually become single-molecule magnets (SMM) under the sole requirement of a highly axial crystal field at the metal ion, the factors influencing the SMM behavior in polynuclear complexes, e
We identified clusters of atypical sensory functioning adults with ASC by hierarchical cluster analysis. A new scale for commonly self-reported sensory reactivity was used as a measure. In a low frequency group (n = 37), all subscale scores were relatively low, in particular atypical sensory/motor reactivity. In the intermediate group (n = 17) hyperreactivity, sensory interests and sensory/motor i
Many animals are known to preferentially mate with partners that are dissimilar at the major histocompatibility complex (MHC) in order to maximize the antigen binding repertoire (or disease resistance) in their offspring. Although several mammals, fish or lizards use odour cues to assessMHCsimilarity with potential partners, the ability of birds to assessMHC similarity using olfactory cues has not
The aggregation of the 42-residue form of the amyloid-β peptide (Aβ42) is a pivotal event in Alzheimer's disease (AD). The use of chemical kinetics has recently enabled highly accurate quantifications of the effects of small molecules on specific microscopic steps in Aβ42 aggregation. Here, we exploit this approach to develop a rational drug discovery strategy against Aβ42 aggregation that uses as
This thesis employs an international comparative perspective to empirically analyse the Czech energy transition between 1830 and 2010. It addresses the utilization of energy in shaping modern economic growth through structural and technological change and the implications of those changes on specialization and foreign trade. New historical data is collected and utilized to investigate the impact o
There is a strong political desire to reduce the use of fossil fuels in road transport. In this paper, the use of e-bikes (of the pedelec type) in Sweden is analysed by focusing on changes in travel behaviour and their corresponding effects on CO2 emissions. The aim is to analyse the effect on CO2 emissions due to the use of e-bikes. The analysis is carried out on the possible differences in chang
BACKGROUND: We previously identified dermicidin (DCD), which encodes a growth and survival factor, as a gene amplified and overexpressed in a subset of breast tumors. Patients with DCD-positive breast cancer have worse prognostic features. We therefore searched for specific molecular signatures in DCD-positive breast carcinomas from patients and representative cell lines.METHODS: DCD expression wa
An alteration of energy balance is the immediate cause of the so-called cachexia. Although alterations of energy intake are often associated with cachexia, it has lately became clear that an increased energy expenditure is the main cause of wasting associated with different types of pathological conditions, such as cancer, infections or chronic heart failure among others. Different types of molecu
Approximately half of all cancer patients present with cachexia, a condition in which disease-associated metabolic changes lead to a severe loss of skeletal muscle mass. Working toward an integrated and mechanistic view of cancer cachexia, we investigated the hypothesis that cancer promotes mitochondrial uncoupling in skeletal muscle. We subjected mice to in vivo phosphorous-31 nuclear magnetic re
INTRODUCTION: Cachexia is a wasting condition that manifests in several types of cancer. The main characteristic of this condition is a profound loss of muscle mass.METHODS: By using a microarray system, expression of several hundred genes was screened in skeletal muscle of rats bearing a cachexia-inducing tumor, the AH-130 Yoshida ascites hepatoma. This model induced a strong decrease in muscle m
BACKGROUND: Cachexia is a wasting condition that manifests in several types of cancer, and the main characteristic is the profound loss of muscle mass.METHODS: The Yoshida AH-130 tumor model has been used and the samples have been analyzed using transmission electronic microscopy, real-time PCR and Western blot techniques.RESULTS: Using in vivo cancer cachectic model in rats, here we show that ske
UNLABELLED: BACKGROUND AND AIMS: The aim of the present investigation was to examine the anti-wasting effects of theophylline (a methylxantine present in tea leaves) on a rat model of cancer cachexia.METHODS: The in vitro effects of the nutraceuticals on proteolysis were examined on muscle cell cultures submitted to hyperthermia. Individual muscle weights, muscle gene expression, body composition
