Article Synopsis
  • Fabry disease (FD) is an X-linked lysosomal storage disorder linked to alpha-galactosidase A deficiency, and this study evaluates whether cardiac magnetic resonance imaging (CMR) can detect sphingolipid accumulation in the kidneys of FD patients.
  • The study involved comparing native T1 values in FD patients (18 participants) and healthy subjects (38 participants) across various organs, including the kidneys, heart, spleen, and liver, using advanced imaging techniques.
  • Results showed no significant differences in native T1 values in the renal cortex between FD patients and healthy individuals, but FD patients had a higher native T1 in the renal medulla and lower T1 in the heart, indicating differences in cardiac involvement but not

Article Synopsis
  • Research on flowering plants has evolved from focusing solely on pollinator specificity to considering introgressive hybridization as a significant factor affecting species relationships.
  • A study on fig trees (Moraceae) uses extensive genetic sampling to explore phylogenetic ties and the role of hybridization among 520 species, revealing that local introgression occurs despite overall reproductive isolation.
  • Findings indicate that while hybridization contributes to plant evolution, strong plant-pollinator relationships can prevent ongoing hybridization between unrelated lineages, maintaining genetic stability in figs.

Background: Fig/wasp pollination mutualisms are extreme examples of species-specific plant-insect symbioses, but incomplete specificity occurs, with potentially important evolutionary consequences. Why pollinators enter alternative hosts, and the fates of pollinators and the figs they enter, are unknown.

Methods: We studied the pollinating fig wasp, , which concurrently interacts with its typical host and the locally sympatric alternative host , recording frequencies of the wasp in figs of the alternative hosts.

Background: In brood site pollination mutualisms, pollinators are attracted by odours emitted at anthesis. In Ficus, odours of receptive figs differ among species and the specific pollinators generally only enter figs of their host species ensuring a pre-zygotic barrier to plant interspecific hybridisation. However, field observations recorded that, in Guangdong province in China, Valisia javana hilli, the local pollinator of F.

Local mate competition (LMC) favours female biased clutch sex ratios because it reduces competition between brothers and provides extra mating opportunities for sons. Fig wasps seem to fit LMC model assumptions and lay female-biased sex ratios as predicted. These female biased sex ratios increase fitness greatly.
