Zebra leaf 15, a receptor-like protein kinase involved in moderate low temperature signaling pathway in rice.

Zebra leaf mutants are an important resource for studying leaf colour in rice. In most such mutants, the zebra leaf phenotype results from defective chloroplast biogenesis. The molecular mechanism by which zebra leaves develop remains unclear, so additional zebra-leaf mutants need to be identified.

Hemorrhagic Retinopathy and Optic Nerve Sheath Hemorrhage Associated With Fatal Subarachnoid Hemorrhage from a Ruptured Intracranial Aneurysm Due to Segmental Fibromuscular Dysplasia.

Fibromuscular dysplasia is an idiopathic, nonatheromatous, and noninflammatory arterial disease that most commonly affects the renal and carotid arteries. We report a child with subarachnoid and ocular hemorrhage associated with an aneurysm due to fibromuscular dysplasia. Computed tomography following a witnessed collapse revealed diffuse subarachnoid hemorrhage and severe cerebral edema. An autopsy confirmed the radiographic findings and detected bilateral retinal hemorrhages, optic nerve sheath hemorrhage...

Different surgical interventions for patients with spontaneous supratentorial intracranial hemorrhage: A network meta-analysis.

Comparison of Traumatic Intracranial Hemorrhage Expansion and Outcomes Among Patients on Direct Oral Anticoagulants Versus Vitamin k Antagonists.

With increasing use of direct oral anticoagulants (DOACs) and availability of new reversal agents, the risk of traumatic intracranial hemorrhage (tICH) requires better understanding. We compared hemorrhage expansion rates, mortality, and morbidity following tICH in patients treated with vitamin k antagonists (VKA: warfarin) and DOACs (apixaban, rivaroxaban, dabigatran).

Anticoagulation reversal for intracranial hemorrhage in the era of the direct oral anticoagulants.

This review focuses on recent relevant literature that examines the reversal of direct oral anticoagulants (DOACs) in patients with intracranial hemorrhage (ICH). The aim of this review is to provide an insightful description of available reversal agents and their clinical utility.

Symptomatic cerebral hyperperfusion following cerebral vasospasm associated with aneurysmal subarachnoid hemorrhage: a case report.

Cerebral hyperperfusion syndrome, which carries a potential risk of intracranial hemorrhage, is a rare and overlooked condition in the setting of subarachnoid hemorrhage (SAH).

How reliable is CT angiography in the etiologic workup of intracranial hemorrhage? A single surgeon's experience.

CT angiography (CTA) is gradually replacing digital subtraction angiography (DSA) in the etiologic workup of intracranial hemorrhage, though debate persists regarding its diagnostic accuracy. To better define the role of CTA in a pragmatic, real-world setting, we reviewed the experience of a single dual vascular-endovascular neurosurgeon.

Mixed-signal intensity in preoperative T1 MRI might be associated with delayed postoperative hemorrhage in patients with intracranial epidermoid cyst.

Delayed postoperative hemorrhage (DPOH) was a severe postoperative complication after intracranial epidermoid cyst (EC) surgery. This study was designed to investigate possible clinical data and image features related to DPOH in EC patients.

Early, Delayed and Expanded Intracranial Hemorrhage in Cerebral Venous Thrombosis.

One of the most important prognostic factors of cerebral venous sinus thrombosis (CVST) is intracranial hemorrhage (ICH). We studied the risk factors, clinical and radiological characteristics of early, delayed and expanded ICH in Iranian patients with CVST.

Effectiveness of low-dose intravenous fentanyl for postoperative headache management after neck clipping of ruptured intracranial aneurysms: Fentanyl for post-subarachnoid hemorrhage headache.

After subarachnoid hemorrhage, headache management is often difficult owing to the need to use multiple analgesic drugs. Fentanyl is an opioid we can use after surgery, and it can decrease pain after subarachnoid hemorrhage. The aim of this study was to investigate the effectiveness and safety of fentanyl for management of headache after subarachnoid hemorrhage.

Repeat surgery after decompressive craniectomy for traumatic intracranial hemorrhage: outcomes and predictors.

Repeat surgery (RS) after decompressive craniectomy/craniotomy (DC) for traumatic intracranial hemorrhage (TICH) is a devastating complication. In patients undergoing DC for TICH, we sought to: a) describe the population requiring RS, b) compare outcomes of those requiring RS to those who did not, and c) discern RS predictors.

Task-driven optimization of the non-spectral mode of photon counting CT for intracranial hemorrhage assessment.

Non-contrast CT is widely employed as the first-line imaging test to evaluate for intracranial hemorrhage (ICH). Advances in MDCT technology have greatly improved the image quality of non-contrast CT (NCCT) for the detection of established, relatively large, and acute ICHs. Meanwhile, the reliability of MDCT in detecting microbleeds and chronic hemorrhage, and in predicting hemorrhagic transformation needs to be further improved. The purpose of this work was to investigate the potential use of non-spectral ...

Association of for-profit hospital ownership status with intracranial hemorrhage outcomes and cost of care.

Much of the current discourse surrounding healthcare reform in the United States revolves around the role of the profit motive in medical care. However, there currently exists a paucity of literature evaluating the effect of for-profit hospital ownership status on neurological and neurosurgical care. The purpose of this study was to compare inpatient mortality, operation rates, length of stay, and hospital charges between private nonprofit and for-profit hospitals in the treatment of intracranial hemorrhage...

Agreement of intracranial vessel diameters measured on 2D and 3D digital subtraction angiography using an automatic windowing algorithm.

Precise vessel measurement plays a major role in size selection of stents used for the treatment of intracranial aneurysms and became even more critical after the introduction of flow diverter stents. We assessed agreement between intracranial vessel diameters of aneurysm patients measured on 2D digital subtraction (2D DSA) and 3D volume rendering digital subtraction angiography (3D DSA) images using an automatic windowing algorithm.

Postoperative hyperglycemia predicts symptomatic intracranial hemorrhage after endovascular treatment in patients with acute anterior circulation large artery occlusion.

Acute phase hyperglycemia is independently associated with an increased risk of death and symptomatic intracranial hemorrhage (sICH) in stroke patients treated with intravenous thrombolysis. Whether postoperative hyperglycemia is an independent predictor of sICH after endovascular therapy remains unknown. Here, we assessed whether hyperglycemia after endovascular therapy can predict sICH.

Periprocedural intracranial hemorrhage after embolization of cerebral arteriovenous malformations: a meta-analysis.

The primary goal of the treatment of cerebral arteriovenous malformations (AVMs) is angiographic occlusion to eliminate future hemorrhage risk.
