Obesity and metabolic syndrome, along with drug dependence (nicotine, alcohol, opiates), are two of the major therapeutic applications for CB(1) cannabinoid receptor antagonists and inverse agonists. In the present study, we report the synthesis and structure-affinity relationships of 1,5-diphenylimidazolidine-2,4-dione and 1,3,5-triphenylimidazolidine-2,4-dione derivatives. These new 1,3,5-tri...

The reactions of isatins, 3-amino-1-pheyl-1H-pyrazol-5(4H)-one, and monocyclic ketones, have been developed for preparation spiro[indoline-3,4'-pyrazolo[3,4-b]quinoline]-2,3'(6'H)-dione, spiro[cyclohepta[b]pyrazolo[4,3-e]pyridine-4,3'-indoline]-2′,3-dione, spiro[cycloocta[b]pyrazolo[4,3-e]pyridine-4,3'-indoline]-2′,3(6H)-dione, spiro[cyclo dodeca[b]pyrazolo[4,3-e]pyridine-4,3'-indoline]-2′,3(6H...

The debate over how much to push the limits of surgical resection for malignant gliomas is not a recent controversy. The cost-benefit analysis about increasing survival with more resection at the expense of function has existed for decades. In 1928, Walter Dandy at the Johns Hopkins Hospital performed hemispherectomies for patients with glioblastoma (GB) and found that these tumors still recurr...

Two enzymes are responsible for the cleavage of pregnane side chains. A steroid-inducible oxygenase, in the presence of reduced nicotinamide adenine trinucleotide and molecular oxygen, catalyzes the conversion of progesterone into testosterone acetate. The latter ester is then hydrolyzed by an esterase to yield testosterone. The oxygenase has been partially purified and separated from the ester...

Background & Objective: Brucellosis is one of the most prevalent bacterial zoonotic diseases which afflicts both humans and animals. Genetic factors play an important role in susceptibility to brucellosis. One of these factors is interferon-gamma (IFN-g), which is vital in the defense mechanism against infectious diseases such as brucellosis. The purpose of this study was to ev...

The title compound, C(13)H(12)O(2)S(2), belonging to the group of dioxoketene cyclic S,S-acetals, was prepared from the corresponding dione in high yield. In the structure, the C=O and C=C bonds are not coplanar, with O=C-C=C torsion angles of -36.8 (4) and -21.0 (4)°. The dithian ring has a twisted conformation.

Enterococcus faecalis is an opportunistic pathogen that causes serious infections in humans and animals and is also an important bacterium for dairy and probiotic supplement production. Therefore, bacteriophages infecting E. faecalis may be useful for phage therapy against multidrug-resistant strains or may threaten industrial fermentation. We isolated a virulent Siphoviridae bacteriophage, BC-...

In the article by Ingeman et al, “Lifestyle Factors and Early Clinical Outcome in Patients With Acute Stroke: A Population-Based Study,” which published online ahead of print on January 16, 2017, and appeared in the March 2017 issue of the journal (Stroke. 2017;48:611–617. DOI: 10.1161/STROKEAHA.116.015784), a correction is needed. On page 611, the corresponding author’s e-mail address is incor...
