Ultrasound-Guided Morcellation During Holmium Laser Enucleation of the Prostate.

Holmium laser enucleation of the prostate (HoLEP) has emerged as an accepted standard of care for the treatment of benign prostatic hyperplasia. This surgery relies on morcellation of the prostate adenoma once enucleation of the transition zone has been completed. Caution is required during this portion of the operation, as engaging bladder mucosa within the morcellator can result in bladder injury, a rare but potentially catastrophic complication of HoLEP.

Tolfenamic Acid Attenuates 3-Nitropropionic Acid-Induced Biochemical Alteration in Mice.

Tolfenamic acid (TA), a nonsteroidal anti-inflammatory drug, shows neuroprotective effects and alleviates cognitive deficits in transgenic mouse models of Alzheimer's disease. However, whether TA can prevent the biochemical alterations induced by intraperitoneal injection of 3-nitropropionic acid (3-NP) in mice is still unknown. In this study, the striatal lesion area was measured by 2,3,5-triphenyltetrazolium chloride staining.

Interdigitated microelectronic bandage augments hemostasis and clot formation at low applied voltage in vitro and in vivo.

Hemorrhage or uncontrolled bleeding can arise either due to a medical condition or from a traumatic injury and are typically controlled with the application of a hemostatic agent. Hemostatic agents are currently derived from animal or human products, which carry risks of blood borne infections and immune dysregulation. Therefore, the need exists for novel biomedical therapies not derived from animal or human products to achieve hemostasis.
