The initiation of reproduction in many seasonally breeding animals is controlled by photoperiod and tends to be clinal populations at higher latitudes breed later than those at lower latitudes, often reflecting a higher photoperiodic threshold. Migratory animals presumably time reproduction to match conditions at their breeding grounds, at least in part, by cues perceived on their wintering grounds. We asked how closely related dark-eyed junco (Junco hyemalis) populations that overwinter in sympatry but breed in allopatry respond to their shared winter environment by comparing early spring indices of readiness to migrate (fat and muscle condition) and breed (baseline and elevated testosterone). We measured stable hydrogen isotopes from feathers grown the preceding year and claws grown during winter to estimate breeding and wintering latitudes, respectively. We predicted that if reproductive initiation is adapted to the emergence of resources at their respective breeding destinations, then birds migrating to higher latitudes (slate-coloured junco; J. h. hyemalis) should delay breeding as compared with those migrating to lower latitudes (pink-sided junco; J. h. mearnsi) despite a common overwinter environment. We found higher testosterone in pink-sided juncos, consistent with earlier reproductive initiation, suggesting local adaptation in reproductive phenology is achieved through differential responses to predictive environmental cues.The fastest land animals are of intermediate size. Cheetah, antelope, greyhounds and racehorses have been measured running much faster than reported for elephants or elephant shrews. Can this be attributed to scaling of physical demands and explicit physiological constraints to supply? Here, we describe the scaling of mechanical work demand each stride, and the mechanical power demand each stance. Unlike muscle stress, strain and strain rate, these mechanical demands cannot be circumvented by changing the muscle gearing with minor adaptations in bone geometry or trivial adjustments to limb posture. Constraints to the capacity of muscle to supply work and power impose fundamental limitations to maximum speed. Given an upper limit to muscle work capacity each contraction, maximum speeds in big animals are constrained by the mechanical work demand each step. With an upper limit to instantaneous muscle power production, maximal speeds in small animals are limited by the high power demands during brief stance periods. The high maximum speed of the cheetah may therefore be attributed as much to its size as to its other anatomical and physiological adaptations.Despite the fast development of technology in the world, diabetic foot wounds cause deaths and massive economical losses. Diabetes comes first among the reasons of non traumatic foot amputations. To reduce the healing time of these fast progressing wounds, effective wound dressings are in high demand. In our study, sheep small intestinal submucosa (SIS) based biocompatible sponges were prepared after SIS decellularization and their wound healing potential was investigated on full thickness skin defects in a diabetic rat model. The decellularized SIS membranes had no cytotoxic effects on human fibroblasts and supported capillary formation by HUVECs in a fibroblast-HUVEC co-culture. Glutaraldehyde crosslinked sponges of three different compositions were prepared to test in a diabetic rat model gelatin (GS), gelatin hyaluronic acid (GSHA) and gelatin hyaluronic acid SIS (GSHASIS). The GSHASIS sponges underwent a 24.8 ± 5.4% weight loss in a 7-day in vitro erosion test. All sponges had a similar Young's modulus under compression but GSHASIS had the highest (5.00 ± 0.04 kPa). Statistical analyses of histopathological results of a 12-day in vivo experiment revealed no significant difference among the control, GS, GSHA, and GSHASIS transplanted groups in terms of granulation tissue thickness, collagen deposition, capillary vessel formation, and foreign body reaction (P > 0.05). On the other hand, in the GSHASIS transplanted group 80% of the animals had a complete epidermal regeneration and this was significantly different than the control group (30%, P  less then  0.05). Preclinical studies revealed that the ECM of sheep small intestinal submucosa can be used as an effective biomaterial in diabetic wound healing.Recently, evidence has been increasing that individuals who are able to narrate coherently about their autobiographical memories, receive more positive social feedback, have higher-quality social relationships and are overall less likely to suffer from internalising psychopathology, like depression and anxiety. However, the relation between narrative coherence and social anxiety, in particular, has not been topic of research until now. This is remarkable, since the concern about negative evaluations by others in social situations is at the core of social anxiety. In the present experimental study (N = 68), we investigated in a two-by-two design how trait and state social anxiety are related to narrative coherence, as well as possible underlying mechanisms. In our study, neither trait nor state social anxiety, nor their interaction had the expected detrimental effect on narrative coherence. However, trait differences in the proposed mechanisms of social anxiety were in line with the literature. Results showed that trait social anxiety and thematic narrative coherence were indirectly negatively related, via the intervening effects of an increased internal focus on anxiety cues, an excessive external focus on negative social evaluation, larger working memory load, more rumination and more depressive symptoms. Limitations and recommendations for future research are addressed.In this study, we examined cultural life scripts in two countries, the Czech Republic and Slovakia. The cultural life script is semantic knowledge about culturally shared expectations regarding the order and timing of important life events during an idealised life course. For many decades, Slovakia and the Czech Republic were one country Czechoslovakia. https://www.selleckchem.com/products/mk-8719.html After a regime change in 1989 and the separation of the Czech Republic and Slovakia in 1993, their two cultures have been evolving and changing independently from one another, making these countries interesting for examining life scripts. We found that the cultural life scripts provided by Slovak and Czech participants shared 25 event categories, representing 89.3% of event categories in the Czech sample and 80.6% of event categories in the Slovak sample (including the category Other). However, participants also reported unique event categories to each culture (10.7% of unique event categories in the Czech sample and 19.4% in the Slovak sample), reflecting the specific cultural characteristics of these two separate countries.
