Patients treated with the immunosuppressive drug tacrolimus (FK506), which binds FK506 binding protein 12 (FKBP12) and then inhibits calcium-dependent phosphatase calcineurin, exhibit decreased regulatory T cells, endothelial dysfunction, hypertension; however, mechanisms whether altered T-cell polarization play a role are unknown. Tacrolimus treatment of mice for 1 week dose-dependently splenic CD4(+)/FoxP3(+) (regulatory cells), increased CD4(+)/IL-17(+) (T-helper 17) caused dysfunction...

Purpose.: Preclinical studies have highlighted retinal oxidative stress in the pathogenesis of diabetic retinopathy. We evaluated whether a treatment designed to enhance cellular catalase reduces cells cultured high glucose and mice corrects an imaging biomarker responsive antioxidant therapy (manganese-enhanced magnetic resonance [MEMRI]). Methods.: Human Müller pigment epithelial were chronically exposed normal or levels treated with cell-penetrating derivative peroxisomal enzyme (called...

Purpose.: The purpose of this study was to investigate the protective mechanisms evoked by TLR2 and MyD88 signaling in bacterial endophthalmitis vivo. Methods.: Endophthalmitis induced wild-type (WT), TLR2−/−, MyD88−/−, Cnlp−/− mice intravitreal injections a laboratory strain (RN6390) two isolates Staphylococcus aureus. Disease progression monitored assessing corneal vitreous haze, burden, retinal tissue damage. Levels inflammatory cytokines/chemokines were determined using quantitative...

Antibiotic resistance in bacteria is a global problem exacerbated by the dissemination of resistant via uncooked food, such as green leafy vegetables. New strains are emerging on daily basis with novel expanded antibiotic profiles. In this pilot study, we examined occurrence against five classes antibiotics iceberg lettuce retailed local convenience stores Rochester, Michigan. 138 morphologically distinct bacterial colonies from 9 samples were randomly picked and tested for resistance. Among...

Purpose: There are currently no means available for the efficient delivery of recombinant proteins into retinal cells in vivo. Although cell-penetrating peptides have been somewhat effective protein to retina, they generally require conjugation chemistry with payload, negatively impacting function therapeutic protein. In this study, we developed a novel peptide (Nuc1) that acts as chaperone small and large molecules, including steroids, peptides, antibodies, proteins, viruses...

Purpose.: To determine the virulence properties of ocular isolates Acinetobacter baumannii in causing endophthalmitis a mouse model. Methods.: Endophthalmitis was induced by intravitreal injections bacteria into C57BL/6 (B6) eyes. The disease progression monitored ophthalmoscopic, electroretinography (ERG), histologic, cell death (TUNEL labeling), and microbiological parameters. expression cytokines/chemokines checked quantitative RT-PCR (qRT-PCR) ELISA. Flow cytometry used to cellular...

Purpose: Acinetobacter (A.) baumannii is an opportunistic pathogen and has been reported as a causative agent of ocular infections. The aim this study to identify virulence properties (biofilm formation, adhesion, invasion cytotoxicity) antibiotic resistance among A. isolates recovered from the eye.Materials Methods: Microscan Walk-Away®, automated bacterial identification susceptibility testing system was used determine resistance. Clonal relatedness assessed by Pulsed-field gel...

Purpose: Many studies have shown improved semen parameters after varicocele surgery; however, the benefit in terms of pregnancy rates and live births is still disputed cases severe oligoasthenozoospermia (OAS).The present study evaluated outcome microscopic subinguinal varicocelectomy spontaneous rate patients with OAS.Materials Methods: This was a retrospective, observational, analytic 56 men OAS who underwent at our center between 2008 2015.The subjects were followed for mean period 12.4...

Azoospermia is a highly evolving subject in the last few decades. In past, use of donor sperm was only option providing realistic chance conception for couples affected by azoospermia. Introduction retrieval techniques and assisted reproductive technologies, especially intracytoplasmic injection (ICSI), has provided these men to father their genetically own child changed management approach significantly.The objective compare rate (SRR) ICSI outcomes surgically retrieved sperms cases...

Background: Oocyte Cryopreservation has become an important part of infertility treatment for various reasons such as fertility preservation in women going oncological treatment; oocyte donation cycles; eliminating several religious, ethical, and legal concerns embryo freezing who wish to delay childbirth. The newer ”vitrification” technique further improved the success rates actual conception than earlier method slow freezing. A successful program can help establishment banks, which would...

Reproductive aging plays a very important role in female fertility.The age-related decline fertility can be attributed to decrease number as well poor quality of oocytes.The trend delay childbearing confronts women with difficulty conception.Oocyte freezing at younger age provides an option freeze the eggs before biological clocks start ticking.It allows their peak and create embryos later stage when they find suitable partner or are ready pursue family.Introduction new "vitrification"...

ABSTRACT Aim To compare reproductive outcomes of day 2 and 3 embryo transfer (ET). Materials methods In this retrospective records study, all couples who underwent in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) ET cycles at Lilavati Hospital & Research Centre over a period 1 year were studied. Data collected analyzed by chi-square test unpaired t -test Statistical Package for the Social Sciences, version 16. Results There was no statistically significant difference...
