Synthesis, and bio-evaluation studies of new isothiocyanate derivatives with respect to COX inhibition and HS release profiles.

The development of HS-donating derivatives of non-steroidal anti-inflammatory drugs (NSAIDs) is considered important to reduce or overcome their gastrointestinal side effects. Sulforaphane, one of the most extensively studied isothiocyanates (ITCs), effectively releases HS at a slow rate. Thus, we rationally designed, synthesized, and characterized new ITC derivatives (I1-3 and I1a-e) inspired by the natural compound sulforaphane.

Synthesis of new imine-/amine-bearing imidazo[1,2-a]pyrimidine derivatives and screening of their cytotoxic activity.

Imidazo[1,2-]pyrimidine derivatives bearing imine groups (-) were successfully synthesized in moderate to good yields using microwave-assisted heating. Corresponding amine derivatives (-) were also obtained by the reduction reaction of the imine derivatives (-). All synthesized products were characterized by FT-IR, H NMR, C NMR, and LC-MS spectroscopic techniques.

Selective and fast magnetic dispersive solid phase micro-extraction of copper and lead in water and vegetables after synthesis of magnetic mesoporous carbon.

Magnetic mesoporous carbon (FeO@C, MMC) was synthesized and characterized. It was used for the first time as a sorbent for the magnetic dispersive solid phase microextraction (M-dSPμE) of copper and lead in water and vegetables. FAAS was used to determine the analyte concentrations after elution.

Looking at NSAIDs from a historical perspective and their current status in drug repurposing for cancer treatment and prevention.

Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most frequently prescribed drug classes with wide therapeutic applications over the centuries. Starting from the use of salicylate-containing willow leaves to the recent rise and fall of highly selective cyclooxygenase-2 (COX-2) inhibitors and the latest dual-acting anti-inflammatory molecules, they have displayed a rapid and ongoing evolution. Despite the enormous advances in the last twenty years, investigators are still in search of the design and development of more potent and safer therapy against inflammatory conditions.

Paving Luteolin Therapeutic Potentialities and Agro-Food-Pharma Applications: Emphasis on Pharmacological Effects and Bioavailability Traits.

Luteolin is a naturally occurring secondary metabolite belonging to the class of flavones. As many other natural flavonoids, it is often found in combination with glycosides in many fruits, vegetables, and plants, contributing to their biological and pharmacological value. Many preclinical studies report that luteolin present excellent antioxidant, anticancer, antimicrobial, neuroprotective, cardioprotective, antiviral, and anti-inflammatory effects, and as a consequence, various clinical trials have been designed to investigate the therapeutic potential of luteolin in humans.

New nimesulide derivatives with amide/sulfonamide moieties: Selective COX-2 inhibition and antitumor effects.

Seventeen new amide/sulfonamide containing nimesulide derivatives were synthesized and characterized by several spectroscopic techniques and primarily investigated for their inhibitory potential on COX enzymes and other pro-inflammatory factors. Experimental analyses showed that among seventeen compounds, N8 and N10 have remarkable potency and selectivity for the COX-2 enzyme over COX-1 at very low doses as compared to nimesulide. Moreover, both N8 and N10 selectively reduced the Lipopolysaccharide (LPS)-stimulated COX-2 mRNA expression level while the COX-1 level remained stable.

Dataset on the differentiation of THP-1 monocytes to LPS inducible adherent macrophages and their capacity for NO/iNOS signaling.

When THP-1 cells are differentiated into adherent macro-phage-like cells, they respond to inflammatory stimuli by changing their phenotypes to an activation state and altering the expression of inflammation-related genes. Nitric oxide (NO) is a diatomic molecule implicating in various pathological conditions including tissue damage, ER stress, obesity, and cancer. The sustained inflammatory microenvironment leads to increased NO release through the activation of the inducible nitric oxide synthase (iNOS) gene in macrophages.

Multitarget Profiling of a Strigolactone Analogue for Early Events of Alzheimer's Disease: In Vitro Therapeutic Activities against Neuroinflammation.

Neuropathological changes in Alzheimer's disease (AD) are directly linked to the early inflammatory microenvironment in the brain. Therefore, disease-modifying agents targeting neuroinflammation may open up new avenues in the treatment of AD. Strigolactones (SLs), subclasses of structurally diverse and biologically active apocarotenoids, have been recently identified as novel phytohormones.

Use and outcomes of amplatz renal dilator for treatment of urethral strictures.

Introduction: Urethral stricture disease is still a major problem in men. Many procedures are available for the treatment of urethral strictures; urethral dilatation is one of the oldest. The blind dilatation of urethral strictures may be a difficult and potentially dangerous procedure.

Retrospective evaluation of urological admissions to emergency service of a training and research hospital.

Objective: Many patients consult emergency services with urological complaints. The aim of this study was to investigate the epidemiology, clinical presentation and treatments of urological emergency cases in a training and research hospital.

Material And Methods: We retrospectively evaluated urological emergency patients referred to the emergency unit between July 2012 and July 2013 according to age, gender, affected organ, radiological imaging techniques and treatment.

Resting eggs as new biosorbent for preconcentration of trace elements in various samples prior to their determination by FAAS.

In this study, the resting eggs of aquatic creatures living in freshwater (Daphnia, Cladocera, Crustacean) ecosystems were used as a novel biosorbent extractant for synchronous preconcentration of trace Cd(II), Co(II), Cu(II), Mn(II), and Ni(II) previous to measurement by flame atomic absorpiton spectrometry (FAAS). Using column procedures, optimization studies were conducted to realize the effective adsorption of the analyte ions such as the solution pH, amount of the biosorbent, volume of the sample, interfering ions, etc. A high preconcentration factor of 67 and low relative standard deflection of ≤4.

The diagnosis and treatment of penile fracture: our 19-year experience.

Background: The aim of this study was to retrospectively evaluate our approach to the diagnosis and treatment of penile fracture.

Methods: We retrospectively evaluated the results of 107 patients with penile fracture treated in our clinic between January 1990 and January 2009. Patient age, etiology of each fracture, history, physical examination results, radiologic findings, type of treatment, and postoperative complications were recorded.

Percutaneous nephrolithotomy in pediatric patients: is computerized tomography a must?

The aim of this study was to retrospectively evaluate the results of pediatric percutaneous nephrolithotomy (PNL) cases, and discuss the results and necessity of non-contrast computerized tomography (CT) in these cases. In all, 48 pediatric patients who underwent PNL were retrospectively evaluated. Before PNL, either intravenous urography or CT was performed.
