Co-catalyst and heterojunction dual strategies to induce photogenerated charge separation for efficient hydrogen evolution of CdS.

The construction of heterojunctions is considered to be an important means to promote efficient electron-hole separation in photocatalysts. However, photocatalysts have poor light absorption ability and a relatively small chance of capturing H, and the stability needs to be improved. In this work, a non-precious metal co-catalyst CuP was introduced for the successful construction of p-n heterojunctions from NiO and CdS to promote charge separation while expanding the light absorption capacity and increasing the chance of H capture, thus enhancing the photocatalytic hydrogen precipitation activity and stability.

Enhanced magnetic resonance imaging manifestations of paediatric intervertebral disc calcification combined with ossification of the posterior longitudinal ligament: case report and literature review.

Background: Since the first description of paediatric intervertebral disc calcification (IDC) by Báron in 1924, only approximately 400 cases have been reported in the literature. Paediatric IDC combined with ossification of the posterior longitudinal ligament (OPLL) is an even rarer condition, with only 8 cases described in detail to date. In this paper, we present a review of the disease characteristics described in the relevant English language literature and discuss the possible mechanisms of lesion enhancement in contrast-enhanced magnetic resonance imaging (MRI).

Sequential occurrence of eclampsia-associated posterior reversible encephalopathy syndrome and reversible splenial lesion syndrome (a case report): proposal of a novel pathogenesis for reversible splenial lesion syndrome.

Background: Posterior reversible encephalopathy syndrome (PRES) is a rare clinic-radiological entity characterized by headache, an altered mental status, visual disturbances, and seizures. Reversible splenial lesion syndrome (RESLES) is a new clinic-radiological syndrome characterized by the presence of reversible lesions with transiently restricted diffusion (cytotoxic edema) in the splenium of the corpus callosum (SCC) on magnetic resonance (MR) images. Here we report a rare case involving a 23-year-old pregnant woman with eclampsia who sequentially developed PRES and RESLES.

Prominent deep medullary veins: a predictive biomarker for stroke risk from transient ischemic attack?

Background Deep medullary veins (DMVs) are a biomarker of severity and prognosis in patients with acute cerebral infarction. However, their clinical significance remains unclear in patients with transient ischemic attack (TIA). Purpose To determine whether prominent deep medullary veins (PDMVs) are a predictive biomarker for stroke risk after TIA.
