In field conditions, we found that males with higher body condition indices express stressed phenotypes more than males with lower body condition indices (p = .002). However, females expressed similar stress loads across all body conditions (p = .900). Testosterone concentrations were assayed in free-living turtles and were not related to any of the immune parameters. Our results suggest that the immune systems play an important role in balancing sex-specific responses to different selective pressures in S. minor.Hydrogen bonding is a key governing force in molecular recognition, notably in biological systems. While it has been studied and exploited by supramolecular chemists for many years, most of this work has been conducted in organic solvents. Investigations in water, the biological solvent, have proceeded more slowly, largely because the interaction is weakened by solvation and less easy to detect. Recently it has become appreciated that the problems should be addressed, and work towards the deployment of H-bonding in water has accelerated. This Minireview discusses a range of synthetic receptors designed to bind organic molecules in aqueous media by combining hydrogen bonding with hydrophobic interactions. Some of these systems are capable of high affinities and selectivities, raising the hope of biomedical applications in the near future.Due to low power consumption, tunable wavelength and long lifetime ultraviolet light-emitting diodes (UV LEDs) have found many applications in different fields such as health care, water disinfection, agriculture. In this review, we report different problems that lead to low external quantum efficiency of UV LEDs. We also report various challenges in the growth process of the UV LEDs such as increase in the dislocation density, which affects the optoelectronic performance of the devices. We also report the analysis of the two modes of light polarization, i.e. transverse e
