Uropathogenic are the main causal agent of urinary tract infections. These diseases can affect more than half of women during their lifetime. Moreover, recurrent urinary tract infections can affect up to 30% of patients, leading to higher social and economic costs for the community.

Here, we report the experimental realization of photonic dimer chains with long-range hopping terms of arbitrary strength and phase, providing a rich generalization of the Su-Schrieffer-Heeger model which, in its conventional form, is limited to nearest-neighbor couplings only. Our experiment is based on a synthetic dimension scheme involving the frequency modes of an optical fiber loop platform.

However, the impact of warming and fragmentation interplay on organismal responses remains largely under-explored, especially when it comes to gut symbionts, which may play a key role in essential host functions and traits by extending its functional and genetic repertoire. Here, we experimentally examined the combined effects of climate warming and habitat connectivity on the gut bacterial communities of the common lizard () over three years.

- Animal dispersal is crucial for ecological and evolutionary processes, yet the genetic factors behind this behavior in vertebrates, like the common lizard, are largely unexplored.
- This study combines genetic analysis techniques to show that the heritability of dispersal is significant, with specific genes related to brain function and circadian rhythms being associated with dispersal behavior.
- The findings suggest that neurotransmitters play a role in regulating dispersal, and that these genetic insights may apply to other vertebrate species, encouraging further research in this area.
Background: During surgery, any mismatch between oxygen delivery (DO) and consumption (VO) can promote the development of postoperative complications. The respiratory exchange ratio (RER), defined as the ratio of carbon dioxide (CO) production (VCO) to VO, may be a useful noninvasive tool for detecting inadequate DO. The primary objective of this study was to test the hypothesis that RER measured during liver transplantation may predict postoperative morbidity.
