Development of a molecularly imprinted membrane for selective, high-sensitive, and on-site detection of antibiotics in waters and drugs: Application for sulfamethoxazole.

Sulfonamides are among the widespread bacterial antibiotics. Despite this, their quick emergence constitutes a serious problem for ecosystems and human health. Therefore, there is an increased interest in developing relevant detection method for antibiotics in different matrices.

Geographical Classification of Saffron ( L.) Using Total and Synchronous Fluorescence Combined with Chemometric Approaches.

There is an increasing interest in food science for high-quality natural products with a distinct geographical origin, such as saffron. In this work, the excitation-emission matrix (EEM) and synchronous fluorescence were used for the first time to geographically discriminate between Moroccan saffron from Taroudant, Ouarzazate, and Azilal. Moreover, to differentiate between Afghan, Iranian, and Moroccan saffron, a unique fingerprint was assigned to each sample by visualizing the EEM physiognomy.

Development of a simplified spectrophotometric method for nitrite determination in water samples.

A new eco-friendly, rapid, and sensitive spectrophotometric method was developed to determine small quantities of nitrite, based on a diazotization mechanism. In an acidic solution, sulfathiazole was first diazotized with sodium nitrite, followed by adding phosphate buffer to form a yellow-colored compound, which showed maximum absorption at 450 nm, without the need for the addition of coupling agents such as N-(1-naphthyl) ethylenediamine. The effects of reagents amount and the optimal experimental conditions were examined by Central composite design.

Community-acquired urinary tract infections caused by complex in patients with no underlying risk factor.

Urinary tract infections (UTIs) remain common infections diagnosed in outpatients as well as hospitalized patients. Community-acquired UTIs are generally caused by and other members of the family is an opportunistic pathogen mainly affecting immunocompromised and hospitalized patients, particularly those who have received prior broad-spectrum antibacterial therapy. Urine samples were collected from 157 outpatients clinically diagnosed with UTI and from 100 healthy control subjects.

Emergency versus elective ureteroscopic treatment of ureteral stones.

Introduction: This retrospective study investigates the role of the emergency ureteroscopic (URS) approach in the definitive treatment of ureteric stones.

Methods: We reviewed all patients admitted for ureteric stones from May 2003 to December 2010. Those who underwent URS stone treatment were selected and stratified into emergency (EMG) and elective groups (ELG).

Clinical comparison of conventional testicular sperm extraction and microdissection techniques for non-obstructive azoospermia.

Background: We compared the efficacy of microdissection testicular sperm extraction (microdissection TESE) and conventional TESE in patients with non-obstructive azoospermia (NOA) and related the positive sperm recovery to certain variables: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels, testicular volume and histology.

Methods: Sperm retrieval rates (SRR) in patients with NOA who underwent microdissection TESE (n = 65) or conventional TESE (n = 68) were compared and related to the different variables.

Results: SRR by microdissection TESE (56.

Urodynamic detrusor overactivity in patients with overactive bladder symptoms.

Purpose: To evaluate the relationship between urodynamic detrusor overactivity (DO) and overactive bladder (OAB) symptoms in men and women.

Methods: We reviewed the records of adult males and females who attended a tertiary referral center for urodynamic evaluation of OAB syndrome symptoms with the presence or absence of DO. DO was calculated for symptoms alone or in combination.
