Comparison of Biofilm Formation Capacities of Two Clinical Isolates of Staphylococcus Epidermidis with and without icaA and icaD Genes on Intraocular Lenses

Türk Oftalmoloji Dergisi, 2017
To compare biofilm formations of two Staphylococcus epidermidis (S. epidermidis) isolates with known biofilm formation capacities on four different intraocular lenses (IOL) that have not been studied before.Two isolates obtained from ocular surfaces and identified in previous studies and stored at -86 °C in 15% glycerol in the microbiology laboratory ...

Investigation of Biofilm Forming Ability in Staphylococci Causing Bovine Mastitis Using Phenotypic and Genotypic Assays

The Scientific World Journal, 2013
A total of 40 S. aureus and 68 coagulase negative Staphylococcus (CNS) isolates from bovine subclinical mastitis were investigated for their ability to form biofilm as one of the most important virulence factors.Using Congo Red Agar (CRA) method, 32.5 ...

Evaluation of biofilm production and prevalence of theicaDgene in methicillin-resistant and methicillin-susceptibleStaphylococcus aureusstrains isolated from patients with nosocomial infections and carriers [PDF]

FEMS Immunology & Medical Microbiology, 2007
Staphylococcus aureus is one of the most important etiological agents responsible for healthcare-associated infections and is capable of producing many virulence factors including biofilm. The aim of the present study was to analyze the correlation between the presence of the icaD and icaA genes and the ability to produce biofilm in vitro in 302 ...

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

Interdisciplinary Materials, EarlyView.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

Caspase‐mediated cleavage events hidden by secondary proteolysis during apoptosis

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Caspases are cysteine proteases that cleave specific proteins to control a range of cellular processes including cell death, inflammation, and differentiation. Proteomic approaches, like N‐terminomics, have been central to identifying both cleaved proteins and where they are cleaved.

Impact of Intracranial Atherosclerosis and Cerebral Small Vessel Disease on Overt Vascular Events During Antithrombotic Therapy

European Journal of Neurology, Volume 33, Issue 6, June 2026.
In this prospective multicenter study, baseline MRI assessed SVD markers and ICAD severity, showing no graded association between ICAD severity and overall SVD burden, although ICAD was linked to more nonlacunar infarcts and fewer PVS. Over a median 2‐year follow‐up, severe‐to‐occluded ICAD independently increased the risk of ischemic events and ...

Detection of icaA, icaD genes and biofilm production by Staphylococcus aureus and Staphylococcus epidermidis isolated from urinary tract catheterized patients

The Journal of Infection in Developing Countries, 2009
Staphylococci are a common cause of catheter-associated urinary tract infections. The present study evaluated biofilm forming capacity and the presence of both icaA and icaD genes among staphylococci strains isolated from patients undergoing ureteral catheterization.Different bacterial strains were isolated from urine and stents segments collected from
