Insights into the molecular mechanism for hyperpolarization-dependent activation of HCN channels
Significance Unlike most other voltage-activated ion channels, hyperpolarization-activated, cyclic nucleotide-gated (HCN) channels open in response to hyperpolarizing membrane voltages.

Toward C13 hyperpolarized biomarkers produced by thermal mixing with hyperpolarized X129e [PDF]
The C13 NMR signal of acetic acid 1-C13-AcH is enhanced by polarization transfer from hyperpolarized X129e using a thermal mixing procedure. 1-C13-AcH acid and hyperpolarized X129e are mixed as gases to disperse X129e in the acetic acid. The mixture is frozen with liquid N2 at 0.5 T.

NKCC1: A key regulator of glioblastoma progression
Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

Effects of methamphetamine on locomotor activity and thalamic gene expression in leptin-deficient obese mice [PDF]
Leptin is an adipose-derived hormone that regulates energy balance. Leptin receptors are expressed in extrahypothalamic sites and several reports showed that leptin can influence feeding and locomotor behavior via direct actions on dopaminergic neurons ...

Nanodiamond-enhanced MRI via in situ hyperpolarization
Nanodiamonds are of interest as nontoxic substrates for targeted drug delivery and as highly biostable fluorescent markers for cellular tracking. Beyond optical techniques, however, options for noninvasive imaging of nanodiamonds in vivo are severely ...
