Activated factor XI (FXIa) inhibitors are promising novel anticoagulants with low bleeding risk compared current anticoagulants. The discovery of potent FXIa good oral bioavailability has been challenging. Herein, we describe our effort, utilizing nonclassical interactions to improve potency, cellular permeability, and by enhancing the binding while reducing polar atoms. Beginning literature-inspired pyridine N-oxide-based inhibitor 1, imidazole linker was first replaced a pyrazole moiety...

Azadirachta indica, the so-called Neem or Nim, is well-known for its biological activities in many countries. The present study aimed at investigating antifeedant properties of hydroalcoholic extract obtained from leaves on Zabrotes fasciatus (Coleoptera: Bruchidae), an insect pest that commonly feeds common bean (Phaseolus vulgaris) during seed storage. We observed displayed significant activity when it was added to diet via Phaseolus vulgaris seeds. Additionally, inhibitory effects this...

Usually occurring entirely intrasellarly or extending suprasellarly (intra-suprasellar), Rathke’s cleft cysts (RCCs) can present with an intrasphenoidal location. Extrasellar positions are rare. To date, only seven patients RCC have been reported in the literature. Despite rarity of condition and lack pathognomonic radiological features, preoperative diagnosis remains challenging. A trans-sphenoidal approach be adopted to treat this type cyst, which has great clinical relevance. Awareness...

Introduction : Proactive esophageal cooling has been FDA cleared to reduce the likelihood of ablation-related injury resulting from radiofrequency (RF) cardiac ablation procedures. Data suggest that procedure times for RF pulmonary vein isolation (PVI) also decrease when proactive is employed instead luminal temperature (LET) monitoring. Reduced may allow increased electrophysiology (EP) lab throughput. We aimed quantify change in EP throughput PVI cases after introduction cooling. Methods...
