Background: In developing countries, rheumatic mitral valve stenosis (MS) is still a problem and its progression leads to left atrial (LA) damage. Due to the complexity of the LA geometry, currently used techniques like antero-posterior dimension (LAD) and 2D echo derived LA volume (LAV) have several limitations that are corrected by 3D derived LA volumes in addition to functional evaluation.

Purpose: To assess the LA functions using 2D speckle tracking echocardiography and 3D transthoracic echocardiography in patients with clinically significant MS in comparison to normal healthy subjects.

Neurodegenerative diseases (NDDs) cause a progressive loss of neurons. Since NDDs are multifactorial, the precise etiology varies on the basis of the type of disease and patient history. Cohort studies and case studies have demonstrated a potential link between viral infections and the onset or progression of NDDs.

Therapeutic drug monitoring is an important clinical testing of the drugs to monitor their concentrations in plasma in order to guarantee their optimal impact, and to avoid any side effects resulting from drug-drug interactions. A green reversed-phase high-performance liquid chromatographic method using a photodiode array detector (RP-HPLC-PDA) was developed for the simultaneous determination of three carbapenem antibiotics (Imipenem, ertapenem, and meropenem) with the co-formulated drug (cilastatin) and contraindicated drugs (probenecid and warfarin) in spiked human plasma. The separation was achieved at 25 °C using a gradient elution of a mixture of mobile phase A: methanol and mobile phase B: phosphate buffer (pH 3.

The eminent aim for advance wound management is to provide a great impact on the quality of life. Therefore, an excellent strategy for an ideal wound dressing is being developed that eliminates certain drawbacks while promoting tissue regeneration for the prevention of bacterial invasion. The aim of this study is to develop a bilayer hybrid biomatrix of natural origin for wound dressing.

Purpose: The aim of this study was to determine the relationship between donor tissue characteristics and surgical outcomes in patients with Fuchs endothelial dystrophy (FED) 2 years after undergoing Descemet stripping automated endothelial keratoplasty (DSAEK).

Methods: A retrospective chart review was performed identifying 70 eyes with FED that underwent DSAEK. Donor endothelial cell density (ECD), donor death to preservation time, donor storage time, donor age, and postoperative recipient ECD were evaluated.

Pseudo-strabismus, or more precisely, pseudo-esotropia, is commonly encountered in pediatric ophthalmology. In our practice, the left eye was reported by parents as being deviated more frequently than the right eye. We attribute this laterality to the fact that most parents are right handed.
