The Development of Polylactic Acid/Multi-Wall Carbon Nanotubes/Polyethylene Glycol Scaffolds for Bone Tissue Regeneration Application.

Composite electrospun fibers were fabricated to develop drug loaded scaffolds to promote bone tissue regeneration. Multi-wall carbon nanotubes (MWCNTs) were incorporated to polylactic acid (PLA) to strengthen electrospun nanofibers. To modulate drug release behavior, different ratios of hydrophilic polyethylene glycol (PEG) were added to composite fibers.

A Case of Left Duplex Kidney with Hydronephrosis Mimicking a Left Renal Cyst in a 29-Year-Old Woman.

BACKGROUND Duplex kidney, also known as duplex renal collecting system, consists of 2 ureters arising from a single kidney and is a common congenital anomaly. The condition is usually an asymptomatic normal variant. However, abnormal anatomic variants such as hydronephrosis, vesicoureteral reflux (VUR), and ureterocele are sometimes observed in a patient with a duplicated kidney.

Benign Neoplasm of Kidney: Angiomyolipoma.

Angiomyolipoma is one of the renal benign neoplasms. The most of the angiomyolipomas are asymptomatic and found incidentally with ultrasound. They are more prevalent in patients with tuberous sclerosis.

Improved emotional stability in experienced meditators with concentrative meditation based on electroencephalography and heart rate variability.

Objective: To determine whether emotional stability distinguishes how experienced and novice meditators react to visual stimuli.

Design: PARTICIPANTS practiced concentrative meditation and then responded to visual stimuli while continuing to meditate.

Participants: Ten experienced and 10 novice meditators responded to sequences of visual stimuli after concentrative meditation.

Increased risk of mortality among haemodialysis patients with or without prior stroke: a nationwide population-based study in Taiwan.

Background & Objectives: Patients with prior stroke (PS) undergoing chronic dialysis are at a high risk of mortality. However, little is known about the cumulative risk and survival rate of dialysis patients with long-term follow up. The aim of this study was to assess risks for mortality between patients with and without PS undergoing chronic haemodialysis (HD).
