Photopharmacological modulation of hippocampal local field potential by caged-glutamate with MicroLED probe.

Aim: Photopharmacology is a new technique for modulating biological phenomena through the photoconversion of substances in a specific target region at precise times. Caged compounds are thought to be compatible with photopharmacology as uncaged ligands are released and function in a light irradiation-dependent manner. Here, we investigated whether a microscale light-emitting diode (MicroLED) probe is applicable for the photoconversion of caged-glutamate (caged-Glu) in vivo.

The impact of cyclooxygenase inhibitor use on urinary prostaglandin metabolites in preterm infants.

Background: There is limited evidence on the association between the clinical course of patent ductus arteriosus (PDA) and prostaglandin (PG) metabolites. This study aimed to determine the influence of PDA treatment on urinary PG metabolite excretion in very-low-birth-weight (VLBW) infants.

Methods: Urine samples were collected from 25 VLBW infants at 1, 3, and 7 days of age.

A novel micro-ECoG recording method for recording multisensory neural activity from the parietal to temporal cortices in mice.

Characterization of inter-regional interactions in brain is essential for understanding the mechanism relevant to normal brain function and neurological disease. The recently developed flexible micro (μ)-electrocorticography (μECoG) device is one prominent method used to examine large-scale cortical activity across multiple regions. The sheet-shaped μECoG electrodes arrays can be placed on a relatively wide area of cortical surface beneath the skull by inserting the device into the space between skull and brain.

A case of neonatal thrombocytopenia due to maternal Helicobacter pylori-associated immune thrombocytopenia.

Many studies in adults have suggested an association between Helicobacter pylori (H. pylori) infection and chronic immune thrombocytopenia (ITP). In adults with ITP and H.
