Conotoxin KM-RIIIJ reveals interplay between K1-channels and persistent sodium currents in proprioceptive DRG neurons.

Voltage-gated potassium channels (VGKCs) comprise the largest and most complex families of ion channels. Approximately 70 genes encode VGKC alpha subunits, which assemble into functional tetrameric channel complexes. These subunits can also combine to form heteromeric channels, significantly expanding the potential diversity of VGKCs.

Graft inflow modulation in recipients with portal hypertension.

The extended application of living donor liver transplantation (LDLT) has revealed the problem of graft size mismatching, potentially leading to the "small-for-size syndrome" (SFSS). SFSS is a rare dysfunction that may affect a partial liver graft, characterized by coagulopathy, cholestasis, ascites, and encephalopathy. A key role in the physiopathology of SFSS is played by portal hypertension (PHT) to which a small allograft is submitted after reperfusion, resulting in sinusoidal congestion and hemorrhage.

Evanescent wave quartz-enhanced photoacoustic spectroscopy employing a side-polished fiber for methane sensing.

We present an all-fiber-based laser gas analyzer (LGA) employing quartz-enhanced photoacoustic spectroscopy (QEPAS) and a side-polished fiber (SPF). The LGA comprises a custom quartz tuning fork (QTF) with 0.8 mm prong spacing, two acoustic micro-resonators (mR) located on either side of the prong spacing, and a single-mode fiber containing a 17 mm polished section passing through both mRs and QTF.

Diagnosis and Treatment of Infantile Hemangioma from the Primary Care Paediatricians to the Specialist: A Narrative Review.

Infantile haemangiomas (IHs) affect 3-10% of infants, 10% of whom need topical or systemic beta-blocker therapy. Propranolol is the first choice for IHs with a high risk of complications. Since more than half of IHs leave a permanent mark, to reduce outcomes, it is essential to start oral propranolol (2-3 mg/kg/day in 2 doses/day) within the 5th month of life (i.
