PURPOSE: Alpha-actinin-3, encoded by the ACTN3 gene, is an actin-binding protein with an important role in myofibril contraction and muscle force output. In humans, there is a relatively common deficiency of the α-actinin-3 due to homozygosity in a polymorphism of the ACTN3 gene (R577X, rs1815739), that has been related to decreased resistance to strain during voluntary muscle contractions. The purpose of this study was to investigate the influence of the ACTN3 genotype on the level of exercise-induced muscle damage attained by 23 experienced triathletes during an official half-ironman competition...

: Race 1 isolates of Fusarium oxysporum f. sp. lycopersici (Fol) are characterized by the presence of AVR1 in their genome. The product of this gene, Avr1, triggers resistance in tomato cultivars carrying resistance gene I In Fol race 2 and race 3 isolates, AVR1 is absent and hence they are virulent on tomato cultivars carrying I In this study, we analyze an approximately 100 kb genomic fragment containing the AVR1 locus of race 1 isolate Fol004, and compare it to the sequenced genome of Fol race 2 isolate 4287 (Fol4287)...

We develop a novel method for classifying melanocytic tumors as benign or malignant by the analysis of digital dermoscopy images. The algorithm follows three steps: first, lesions are extracted using a self-generating neural network (SGNN); second, features descriptive of tumor color, texture and border are extracted; and third, lesion objects are classified using a classifier based on a neural network ensemble model. In clinical situations, lesions occur that are too large to be entirely contained within the dermoscopy image...

DNA sequencing advances through next-generation sequencing (NGS) and several practice changing events, have led to shifting paradigms for inherited cancer predisposition testing. These changes necessitated a means by which to maximize health benefits without unnecessarily inflating healthcare costs and exacerbating health disparities. Areas covered: NGS-based tests encompass multi-gene panel tests, whole exome sequencing, and whole genome sequencing, all of which test for multiple genes simultaneously, compared to prior sequencing practices through which testing was performed sequentially for one or two genes...

Happiness is a feeling that is desired by every human being. To achieve happiness, human try various routes like, to gain financial superiority, fame, entertainment, assets and so on. But on the contrary, religiosity is claimed to be a technique to attain purpose in life, mental health, physical well-being and internal peace, which ultimately leads to happiness in life. This study analyses the studies conducted in last two decades toward understanding the relationship between religiousness and happiness. These studies have been organised in terms of the religions, geographic locations, scales and significance...

Our understanding of the mechanisms through which racial/ethnic disparities in disability in older adults develop and are maintained is limited. We examined the role of physical impairment, socioeconomic factors and health for racial/ethnic disparities in activities of daily living (ADL), and the modifying role of the indoor home environment. Data come from the National Health and Aging Trends Study (N = 5,640), and negative binomial regression models were specified separately for men and women. Blacks and Hispanics reported more ADL difficulty than Whites...

: Compared to White individuals and men, Black individuals and women demonstrate a lower tolerance for experimental pain stimuli. Previous studies suggest that pain catastrophizing is important in this context, but little is known about which components of catastrophizing contribute to these race and sex differences. The purpose of the current study was to examine the individual components of catastrophizing (rumination, magnification, and helplessness) as candidate mediators of race and sex differences in experimental pain tolerance...

Heat shock proteins 70 (HSP70s) are molecular chaperones that aid in protection against environmental stress. In this study, we cloned and characterized five members of the HSP70 family (designated as HSPa1a, HSC70-1, HSC70-2, HSPa4 and HSPa14) from Lateolabrax maculatus using rapid amplification cDNA ends (RACE). Multiple sequence alignment and structural analysis revealed that all members of the HSP70 family had a conserved domain architecture, with some distinguishing features unique to each HSP70. Quantitative real-time (qPCR) analysis revealed that all members of the HSP70 family were ubiquitously and differentially expressed in all major types of tissues, including testicular tissue...

Shayanne Chantall-Rocha, Hilton F Japyassú
Male-female courtship signals are frequently subject to arms races, with patterns of behaviour evolving reciprocally to manipulate the reproductive output. Female resistance should be particularly effective when asymmetrical offspring care occurs under low and unpredictable resource distribution, because this would increase maternal costs. Our hypothesis is that under these conditions females will evolve diffuse mating strategies to avoid predictable exploitation by male optimal counter tactics. Mating in scorpions is a complex process, and female resistance occurs through specific behaviours...
