Comparison of embryo morphokinetics following intracytoplasmic sperm injection in smoker and non-smoker couples: Are the results different?

Objective: To assess early embryo development via time-lapse in smokers and non-smokers.

Methods: The retrospective study was conducted at Novafertil IVF centers in Konya, Turkey and comprised oocytes of both smoker and non-smoker couples subjected to in vitro fertilisation / introcytoplasmic sperm injection from 2012 to 2015. Age, basal follicle-stimulating hormone, number of stimulation days, amount of gonadotropin used, number of metaphase II oocytes, number of embryos transferred and pregnancy, abortus and clinical pregnancy rates were noted.

GnRH agonist triggering affects the kinetics of embryo development: a comparative study.

Background: To evaluate the effects of an ovulation triggering agent, human chorionic gonadotropin (hCG), versus a gonadotropin-releasing hormone agonist (GnRHa) on early embryo development in vitro using a time-lapse system.

Methods: Retrospective analysis of a prospectively collected database. A total of 739 embryos from 152 infertile couples undergoing intracytoplasmic sperm injection cycles.

[Investigation of biofilm-associated antibiotic susceptibilities of methicillin-resistant staphylococci isolated from catheter-related nosocomial infections].

Risks for development of local and/or systemic infections are the most important complications of catheters that are widely used during hospitalization process. The aims of this study were to investigate and compare the antibiotic susceptibilities of methicillin-resistant staphylococci isolated from catheters, in planktonic and biofilm forms, and to evaluate the antimicrobial effects of antibiotics on those forms alone and in combinations. A total of 30 strains [15 methicillin-resistant Staphylococcus aureus (MRSA) and 15 methicillin-resistant coagulase-negative staphylococci (MR-CNS)] isolated from catheter cultures of patients hospitalized in different clinics and intensive care units in Baskent University Medical School Hospital between 2006-2009, were included in the study.

[The performance of two different chromogenic media for the diagnosis of extended spectrum beta-lactamase producing strains].

The aim of this study was to evaluate the performances of 2 different chromogenic media for the detection of extended spectrum beta-lactamase (ESBL) producing Escherichia coli and Klebsiella spp. isolated from different clinical samples of patients who were admitted to Baskent University Faculty of Medicine, Adana Application and Research Hospital between September to November 2007. A total of 365 strains [251 were ESBL positive and 114 were negative by double disc synergy (DDS) test] of which 255 were E.

[Activity of tigecycline on planktonic and sessile cells of Acinetobacter baumannii].

Acinetobacter baumannii is an important pathogen, capable of survival for very long periods on various surfaces in the hospital environment. Tigecycline is a commonly used antimicrobial agent especially for the treatment of resistant infections. The aim of this study was to investigate the activity of tigecycline on both planktonic and sessile biofilm cells of A.

Synthesis and antioxidant properties of novel N-methyl-1,3,4-thiadiazol-2-amine and 4-methyl-2H-1,2,4-triazole-3(4H)-thione derivatives of benzimidazole class.

Some novel 1-methyl-4-(2-(2-substitutedphenyl-1H-benzimidazol-1-yl)acetyl)thiosemicarbazides (16a-20a), 5-[(2-(substitutedphenyl)-1H-benzimidazol-1-yl)methyl]-N-methyl-1,3,4-thiadiazol-2-amines (17b-20b), and 5-[(2-(substitutedphenyl)-1H-benzimidazol-1-yl)methyl-4-methyl-2H-1,2,4-triazole-3(4H)-thiones (16c-20c) were synthesized and tested for antioxidant properties by using various in vitro systems. Compounds 16a-20a were found to be a good scavenger of DPPH radical (IC(50), 26 microM; IC(50), 30 microM; IC(50), 43 microM; IC(50), 55 microM; IC(50), 74 microM, respectively) when compared to BHT (IC(50), 54 microM). Noteworthy results could not be found on superoxide radical.
