Parent Artery Chronical Occlusion after Endovascular Treatment of a Unruptured "True" Posterior Communicating Artery Aneurysm.

A case of a patient with a true large unruptured posterior communicating artery (PCoA) aneurysm in a distal segment of PCoA, who was treated by interventional therapy via an ipsilateral occlusion of the internal carotid artery (ICA), is reported. Although the treatment went very well and the patient recovered very well, angiography 6 months after the operation showed that left PCoA had occluded and the aneurysm disappeared. The temporary recanalization of occluded ophthalmic segment of ICA can be a pathway for interventional therapy.

Integrated Management Practices for Canopy-Topsoil Improves the Grain Yield of Maize with High Planting Density.

Inappropriate spatial distribution of canopy and roots limits further improvements to the grain yield of maize with increased planting density. We explored an integrated management practice called strip deep rotary with staggered planting (SRS) which includes comprehensive technology for both canopy layers and topsoil. Here, field experiments were conducted under two maize cropping systems (spring maize and summer maize) to evaluate the effect of SRS on the spatial distribution of the canopy and roots for maize under high planting density (90,000 plants ha) and to determine the physiological factors involved in yield formation.

A rare case of aortic arch variation complicated with multiple ruptured intracranial aneurysms.

Objectives: Previous reports on aortic arch variations have emphasized on its cardiovascular significance. We present a case of a rare variation of aortic arch complicated with multiple ruptured intracranial aneurysms.

Methods: This case report reviews the effects of the diameter of internal carotid artery of isolated origins on cerebral vessels.

Methodological, reporting, and evidence quality of systematic reviews of traditional Chinese medicine for ischemic stroke.

The aim of this study is to critically appraise whether published systematic reviews/meta-analyses of traditional Chinese medicine for adults with ischemic stroke are of sufficient quality and to rate the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation approach. A literature search was performed in the Cochrane Library, PubMed, Chinese National Knowledge Infrastructure, and SinoMed databases by March 2022. The inclusion criteria were systematic reviews/meta-analyses of traditional Chinese medicine in adults who suffered from ischemic stroke.

Understanding physiological mechanisms of variation in grain filling of maize under high planting density and varying nitrogen applicate rate.

Grain filling is a critical process for achieving a high grain yield in maize ( L.), which can be improved by optimal combination with genotype and nitrogen (N) fertilization. However, the physiological processes of variation in grain filling in hybrids and the underlying mechanisms of carbon (C) and N translocation, particularly under various N fertilizations, remain poorly understood.

Adjusting sowing date improves the photosynthetic capacity and grain yield by optimizing temperature condition around flowering of summer maize in the North China Plain.

Adjusting the sowing date to optimize temperature conditions is a helpful strategy for mitigating the adverse impact of high temperature on summer maize growth in the North China Plain (NCP). However, the physiological processes of variation in summer maize yield with sowing date-associated changes in temperature conditions around flowering remain to be poorly understood. In this study, field experiments with two maize varieties and three sowing dates (early sowing date, SD1, 21 May; conventional sowing date, SD2, 10 June; delay sowing date, SD3, 30 June) were conducted at Xinxiang of Henan Province in 2019 and 2020.

Traumatic bifrontoparietal extradural hematomas with detachment of superior sagittal sinus: a case report and review of the literature.

A 45-year-old man suffered bifrontoparietal extradural hematoma resulting from head injury, which cause superior sagittal sinus detachment from its subperiosteal loggia. We present the patient who was treated by early surgical evacuation of the hematoma with an excellent outcome and we also perform a review of the current literature.

Subsoiling practices change root distribution and increase post-anthesis dry matter accumulation and yield in summer maize.

Subsoiling is an important management practice for improving maize yield, especially for maize planted at high plant density. However, the affected physiological processes have yet to be specifically identified. In this study, field experiments with two soil tillage (CK: no-tillage, SS: subsoiling) and three planting densities (low: 45000 plants ha-1, medium: 67500plants ha-1, and high: 90000 plants ha-1) were conducted from 2010 to 2012 at Xinxiang, Henan province.

Soil Tillage Management Affects Maize Grain Yield by Regulating Spatial Distribution Coordination of Roots, Soil Moisture and Nitrogen Status.

The spatial distribution of the root system through the soil profile has an impact on moisture and nutrient uptake by plants, affecting growth and productivity. The spatial distribution of the roots, soil moisture, and fertility are affected by tillage practices. The combination of high soil density and the presence of a soil plow pan typically impede the growth of maize (Zea mays L.
