Comparison of the outcomes of normal vaginal delivery with and without spinal anesthesia in mothers admitted to the maternity ward of Firoozabadi Hospital.

Introduction And Objective: The study of the methods of controlling labor pain is very important. One of the methods of pain relief is spinal anesthesia. Due to the different opinions about the effects of spinal anesthesia on the delivery process and maternal and fetal consequences, this study aimed to evaluate the effects of spinal anesthesia and compare it with normal vaginal delivery without spinal anesthesia.

Synthesis of Some Spiro Indeno[1,2-]pyrido[2,3-]Pyrimidine-5,3'-Indolines as New Urease Inhibitors.

New series of spiro indeno[1,2-]pyrido[2,3-]pyrimidine-5,3'-indolines as new urease inhibitors were synthesized by the catalytic procedure in high yield and short reaction time. In this method, biacidic carbon was prepared as a novel heterogeneous acid and was subsequently used as an efficient catalyst. The inhibitory activities of synthesized compounds were tested against Jack bean urease using Berthelot colorimetric assay and docking simulation using AutoDock 4.

Green Synthesis and Urease Inhibitory Activity of Spiro-Pyrimidinethiones/Spiro-Pyrimidinones-Barbituric Acid Derivatives.

Sulfonic acid functionalized SBA-15 (SBA-Pr-SO3H) with pore size 6 nm as an efficient heterogeneous nanoporous solid acid catalyst exhibited good catalytic activity in the Biginelli-like reaction in the synthesis of spiroheterobicyclic rings with good yield and good recyclability. Spiro-pyrimidinethiones/spiro-pyrimidinones-barbituric acid derivatives were synthesized in a simple and efficient method using the one-pot three-component reaction of a cyclic 1,3- dicarbonyl compounds (barbituric acid), an aromatic aldehyde and urea or thiourea in the presence of nanoporous silica SBA-Pr-SO3H under solvent free conditions. Urease inhibitory activity of spiro compounds were tested against Jack bean urease using Berthelot alkaline phenol-hypochlorite method.

The molecular diversity scope of 1,3-indandione in organic synthesis.

Indandione is an important starting material that has drawn great attention in various organic transformations because of its attributes, such as low cost, easy to handle and eco-friendliness generally affording the corresponding products in excellent yields. In this review, we summarize recent data describing the most important MCRs reactions in which one of the starting materials is indandione. This review will also present two-, three-, four-, and five-component and one-pot reactions for the functionalization of indandione with the to increase awareness on the versatility of using this compound among organic chemists.

Evaluation of attention-deficit hyperactivity disorder risk factors.

Background. Attention-deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders among children. The aim of this study was to evaluate risk factors for ADHD in children.

Recent progress in asymmetric Biginelli reaction.

The Biginelli reaction, which involves the interaction of ethyl acetoacetate, urea, and an appropriate aryl aldehyde, was first discovered by Pietro Biginelli about 120 years ago. The Biginelli products (3,4-dihydropyrimidin-2(1H)-ones) are interesting materials due to their significant pharmacological and structural profiles. In the last decades, the asymmetric synthesis as a powerful tool has an effective impact on the Biginelli products and has increased their potencies and applications as drugs.

Three-component synthesis of pyrano[2,3-d]-pyrimidine dione derivatives facilitated by sulfonic acid nanoporous silica (SBA-Pr-SO3H) and their docking and urease inhibitory activity.

Background: A straightforward and efficient method for the synthesis of pyrano[2,3-d]pyrimidine diones derivatives from the reaction of barbituric acid, malononitrile and various aromatic aldehydes using SBA-Pr-SO3H as a nanocatalyst is reported.

Results: Reactions proceed with high efficiency under solvent free conditions. Urease inhibitory activity of pyrano[2,3-d]pyrimidine diones derivatives were tested against Jack bean urease using phenol red method.
