A new palladium-catalyzed C-H bond activation-annulation-amination tandem method was presented for selectively synthesizing 3-(aminomethylene)-2-oxoindolines. In the presence of Pd(dba)(2), xantphos (L8), AgOAc and Na(2)CO(3), a variety of 3-chloro-2-iodo-N-arylacrylamides underwent the reaction with amides or amines to afford the corresponding 3-(aminomethylene)-2-oxoindolines in moderate to good yields.

Background: Overdose of acetaminophen (APAP), a commonly used antipyretic analgesic, can lead to severe liver injury and failure. Current treatments are only effective in the early stages of APAP-induced acute liver injury (ALI). Therefore, a detailed examination of the mechanisms involved in liver repair following APAP-induced ALI could provide valuable insights for clinical interventions.

Objective: To assess the outcome of prolonged treatment with paracetamol in the closure of hemodynamically significant patent ductus arteriosus in preterm newborns.
Patients And Method: Retrospective study in VLBW infants with echocardiographic and clinical diagnosis of hs-PDA who received treatment with intravenous paracetamol at 15 mg/kg every 6 hours for 6 days.
Pain Management in Brugada Syndrome: A Case Report and Review.

Brugada syndrome is a rare condition that increases the risk of life-threatening arrhythmias. Although there are existing anesthesia recommendations for patients with Brugada syndrome, guidance on pain management is limited. We present a novel approach to pain management in these patients, illustrated by the case of a young woman with Brugada syndrome who underwent ropivacaine peripheral nerve infusion and intravenous ketamine infusion for acute-on-chronic left upper limb pain.

Cells die by necrosis due to excessive chemical or thermal stress, leading to plasma membrane rupture, release of intracellular components and severe inflammation. The clearance of necrotic cell debris is crucial for tissue recovery and injury resolution, however, the underlying mechanisms are still poorly understood, especially . This study examined the role of complement proteins in promoting clearance of necrotic cell debris by leukocytes and their influence on liver regeneration.

Ceramide (Cer) is synthesized in the endoplasmic reticulum (ER) using sphinganine as the common backbone and is then transported to the Golgi apparatus to synthesize two complex sphingolipids, sphingomyelin (SM) and glucosylceramide (GlcCer). Brefeldin A (BFA) affects the structure of the Golgi apparatus, resulting in the redistribution of the Golgi proteins into the ER. Therefore, BFA has been used to examine the ER-to-Golgi trafficking of lipids, but the detailed lipid changes in cells upon BFA treatment are not fully understood.
