Intracranial germ cell tumor metastasis to the peritoneal cavity through the ventriculoperitoneal shunt

Journal of Medical Sciences, 2020
Intracranial germ cell tumors (GCTs) are uncommon and may cause obstructive hydrocephalus, making adequate drainage necessary in symptomatic patients. Here, we present the case of a 36-year-old male patient with intracranial germinoma metastasis to the ...

Ge‐Based Visible‐Infrared Bipolar Floating‐Gate Phototransistor for Broad‐Spectrum Retinal Bionics

Advanced Science, EarlyView.
A germanium (Ge)‐based floating‐gate tungsten diselenide (WSe2) phototransistor capable of mimicking broad‐spectrum bipolar cell functionality is proposed. Under different bottom gate voltage pulse modulations, the device exhibits bipolar response under both visible and near‐infrared light illumination.

Boosting Electrochemical Capacitive of Ultrathin Shower‐Pouf Birnessite‐Type MnO2 for Porous High‐Mass‐Loading Energy Storage Device

Advanced Science, EarlyView.
Ultrathin Shower‐pouf Birnessite‐type MnO2 (thickness: ~3 nm) has been fabricated via the specific adsorption of fluoride ions on the (001) crystal plane of birnessite. By constructing an electrically conductive network and optimizing electrode slurry concentration, the electrode mass loading can be substantially improved. These electrodes also exhibit

Unravelling the Functional Diversity of Type III Polyketide Synthases in Fungi

Angewandte Chemie, EarlyView.
Type III polyketide synthases (T3PKSs) produce diverse compounds of ecological and clinical importance. Here, the activity of 37 fungal T3PKSs was profiled, revealing unexpected products and generating several pharmaceutical precursors. The machine learning model trained on the activity data accurately extrapolates the predictions to other enzymes and ...

Mechanical shunt failure in hydrocephalus: a common but remediable complication with technical nuances

Egyptian Journal of Neurosurgery
Background A ventriculoperitoneal (VP) shunt is a cerebral shunt that diverts excess cerebrospinal fluid (CSF).Obstruction in the normal outflow or decreased absorption of the fluid is the usual cause.
