Article Synopsis
- - A whole-cell biosensor called acinetobacter ADP1_pWHlux was genetically engineered for detecting acute toxicity in challenging environments, showing promising results compared to natural luminescent bacteria.
- - The biosensor effectively demonstrated a dose-response relationship, indicating that its luminescence decreases with higher levels of acute toxins, with a quick response to mercury (HgCl2) and low detection limits for various heavy metals.
- - The developed biosensor has been successfully tested for detecting acute toxicity in the Qinghe river's water in Beijing, proving its potential for monitoring water quality and contamination.
Article Synopsis
- * Researchers analyzed data from 600 patients and conducted dissections on 33 cadavers to identify the sources of blood supply to the extrahepatic bile duct; they found most of the supply comes from the gastroduodenal artery.
- * The findings suggest that preserving the gastroduodenal artery during liver transplants is crucial for enhancing surgical success rates and decreasing the likelihood of bile duct complications.
Expression of caspase-8 and caspase-9 in rat hippocampus during postnatal development.

February 2011
The role of caspases in the regulation of apoptosis of neurons during development is well established. An emerging body of evidence indicates that caspases may also play significant roles which are nonapoptotic. We have demonstrated previously that the executor caspase-3 exhibited a unique pattern of spatiotemporal expression in the postnatal rat hippocampal subregions, and the activation of caspase-3 in different hippocampal neurons appeared to have distinct roles during postnatal development.

Methods: Pregnant rats were randomly divided into 4 groups: normal control, IUGR model, low dose (100 mg/kg x d) and high dose (300 mg/kg x d) taurine treatment IUGR (n = 5 each). IUGR was induced by food restriction throughout pregnancy.
Background: Transplanting a vascularized autologous submandibular gland (SMG) is considered an effective method to treat severe keratoconjunctivitis sicca. But the operation may fail due to the anatomic variances in the blood vessels of SMG. The present study aimed to investigate the submandibular glands at the microanatomy level.
