Development of a miniaturized, reconnectable, and implantable multichannel connector.

. Connectors for implantable neural prosthetic systems provide several advantages such as simplification of surgery, safe replacement of implanted devices, and modular design of the implant systems. With the rapid advancement of technologies for neural implants, miniaturized multichannel implantable connectors are also required.

The Long-Term Functional Effect of Thrombectomy on Patients with Middle Cerebral Artery Occlusion Who Exhibit Moderate to Severe Disability.

: Endovascular thrombectomy (EVT is an emerging gold standard treatment for acute cerebral infarction and may allow functional improvement after subacute cerebral infarction. However, the long-term functional benefits of EVT in patients with moderate to severe disability remain unclear. We investigated the effects of EVT on the activities of daily living (ADL), handicap, gait, and eating in patients with middle cerebral artery (MCA) occlusion who exhibited moderate to severe disability (score of 3-5 on the modified Rankin scale (mRS)) due to stroke, up to six months after onset.

Totally implantable enzymatic biofuel cell and brain stimulator operating in bird through wireless communication.

Animals digest food to fuel brain neurometabolism via cellular respiration. This study demonstrates the combination of a biofuel cell (BFC) and an animal brain stimulator (ABS) implanted in a pigeon. Glucose oxidation and oxygen reduction in an enzymatic BFC supplied electrical power to the ABS.

The Role of digital subtraction angiography in the ventricular spot sign on the computed tomography angiography.

Objective: The spot sign on computed tomography angiography is little known about the relationship between the spot sign and the results of cerebral angiography We retrospectively analyzed the spot sign, digital subtraction angiography results, and other factors.

Material And Methods: From December 2009 to May 2014, DSA was performed in 52 ICH patients with non-specific location or abnormalities on CTA findings. 26 of those patients, whose initial CTA showed the spot sign, were analyzed.

A handheld neural stimulation controller for avian navigation guided by remote control.

Background: Animal learning based on brain stimulation is an application in a brain-computer interface. Especially for birds, such a stimulation system should be sufficiently light without interfering with movements of wings.

Objective: We proposed a fully-implantable system for wirelessly navigating a pigeon.

Significance of intracranial pressure monitoring after early decompressive craniectomy in patients with severe traumatic brain injury.

Objective: Early decompressive craniectomy (DC) has been used as the first stage treatment to prevent secondary injuries in cases of severe traumatic brain injury (TBI). Postoperative management is the major factor that influences outcome. The aim of this study is to investigate the effect of postoperative management, using intracranial pressure (ICP) monitoring and including consecutive DC on the other side, on the two-week mortality in severe TBI patients treated with early DC.

Neurolysis for meralgia paresthetica.

Objective: Meralgia paresthetica (MP) is a syndrome of pain and/or dysesthesia in the anterolateral thigh that is caused by an entrapment of the lateral femoral cutaneous nerve (LFCN) at its pelvic exit. Despite early accounts of MP, there is still no consensus concerning the effectiveness of neurolysis or transaction treatments in the long-term relief for medically refractory patients with MP. We retrospectively analyzed available long-term results of LFCN neurolysis for medically refractory MP in an effort to clarify this issue.

Hypothermia blocks ischemic changes in ubiquitin distribution and levels following stroke.

Dysfunction of the ubiquitin-proteasome system has recently been linked to stroke. Ischemia may cause increased protein misfolding and inhibit the proteasome, shifting the balance from free ubiquitin to conjugated ubiquitin. In this study, we examine the effect of hypothermia on the distribution of total and free ubiquitin, as well as the levels of conjugated ubiquitin after experimental stroke using a focal cerebral ischemia model.

Intraspinal extradural teratoma mimicking neural sheath tumor in infant.

Introduction: An intraspinal teratoma that is located entirely extradurally is unusual both in children and in adults.

Case History: The authors present a case of an 8-month-old male infant with an extradurally arising intraspinal mature teratoma located from T-2 to T-4, who had suffered from progressive paraparesis (grade 1). The patient did not have any stigmata or anomalies suggesting spinal dysraphism.

Posteroventral pallidotomy in medically intractable postapoplectic monochorea: case report.

Background: Posteroventral pallidotomy is a widely accepted surgical procedure for treating medically intractable Parkinson's disease and Levo-dopa induced dyskinesia. In the surgical treatment of hyperkinetic movement disorders, generalized dystonia has recently become a favorable indication of posteroventral pallidotomy. However, a commonly recognized surgical procedure for treating choreiform movement disorders has not yet been established.
