Discovery and biological evaluation of nitrofuranyl-pyrazolopyrimidine hybrid conjugates as potent antimicrobial agents targeting and methicillin-resistant .

Nitrofuran and pyrazolopyrimidine-based compounds possess a broad antimicrobial spectrum including Gram-positive and Gram-negative bacteria. In the present work, a series of conjugates of these scaffolds was synthesized and evaluated for antimicrobial activity against and methicillin-resistant (MRSA). Many compounds showed MIC values of ≤2 μg ml, with compound 35 demonstrating excellent activity (MICs: 0.

Efficacy of Intraoperative Cell Salvage on Perioperative Blood Transfusion in Pelvic and Acetabular Surgery: A Matched Cohort Analysis.

Background: Pelvic fractures often result in traumatic and intraoperative blood loss. Cell salvage (CS) is a tool where autologous blood lost during surgery is collected and recycled with anticoagulation, centrifugation to separate red blood cells, and washing to be reinfused back to the patient. The purpose of this study was to investigate our experience with CS in pelvic and acetabular surgery and its relationship to perioperative transfusion requirements.

Highly Position- and Enantioselective Catalytic Epoxidation of Polyolefins Mediated by a Chiral Mn Complex, Including a One-Step Conversion of Squalene to the ()-2,3-Epoxide, a Precursor of Natural Steroids and Terpenoids.

Reported herein is the synthesis of a novel chiral dicarboxylic ligand for Mn(II) and the application of the Mn complex to the highly enantio- and position-selective epoxidation of C═C under mild conditions, even with polyolefinic substrates. A stereomechanistic basis for asymmetric induction is suggested.

Safety and Phosphate-Binding Capacity of Oxylanthanum Carbonate in Healthy Volunteers.

Despite the widespread use of currently available serum phosphate management options, elevated serum phosphate is common in patients with end-stage kidney disease on dialysis. Characteristics of currently available phosphate binders that lead to poor patient experiences such as large drug volume size of required daily medication (e.g.

Ecological interactions, host plant defenses, and control strategies in managing soybean looper, (Lepidoptera: Noctuidae).

Soybean looper (SBL), (Walker 1858) (Lepidoptera: Noctuidae), is one of the most damaging insect pests of soybean, (L.) Merr., in the mid-south region of the United States, and causes significant economic losses to cotton, sunflower, tomato, and tobacco crops in the United States, Brazil, and Argentina.
