Early-onset, severe retinal dystrophy can be isolated or syndromic, presenting as part of an underlying systemic disease. Mainzer-Saldino syndrome, a rare systemic ciliopathy characterized by skeletal and renal disease, is caused by recessive mutations in the intraflagellar transport 140 chlamydomonas homologue (IFT140) gene. We present a series of 13 cases of early-onset retinal dysfunction with confirmed IFT140 mutations from 8 unrelated Saudi families belonging to 3 well-known tribes.

Article Synopsis
  • - Type 1 diabetes (T1D) is caused by autoimmune destruction of insulin-producing β-cells, with macrophages playing a key role in this process through lipid signaling.
  • - Reducing myeloid-iPLA2β in NOD mice leads to less inflammation, encourages a shift to anti-inflammatory macrophages, and decreases T-cell activation, which is linked to lower T1D rates.
  • - Targeting iPLA2β in macrophages presents a promising strategy to slow down or prevent the onset of T1D by modulating inflammatory responses.

  • Chlorine, particularly sodium hypochlorite (NaOCl), is used to combat Salmonella contamination in poultry processing; this research assessed its effectiveness against four Salmonella serotypes.
  • The addition of radical scavenger thiourea or iron chelator Dip increased the survival rates of Salmonella compared to NaOCl alone, with thiourea providing better protection.
  • The study also found that certain genetic mutations in E. coli affecting reactive oxygen species (ROS) production had different impacts on survival, indicating that ROS plays a critical role in NaOCl's ability to kill Salmonella and that metabolic pathways differ between these bacteria.
