Extracellular HSPA5 is autocrinally involved in the regulation of neuronal process elongation.

The molecular mechanisms by which neuronal processes grow are extremely complicated, involving fine-tuned regulation of extracellular and intracellular signals. It remains to be elucidated which molecules are contained in the regulation. Herein, we report for the first time that heat shock protein family A member 5 (HSPA5, also called immunoglobulin heavy chain binding endoplasmic reticulum [ER] protein [BiP]) is secreted from mouse primary dorsal neuronal ganglion (DRG) cells or neuronal cell line N1E-115, a frequently used neuronal differentiation model.

The Antiepileptic Valproic Acid Ameliorates Charcot-Marie-Tooth 2W (CMT2W) Disease-Associated HARS1 Mutation-Induced Inhibition of Neuronal Cell Morphological Differentiation Through c-Jun N-terminal Kinase.

Hereditary peripheral neuropathies called Charcot-Marie-Tooth (CMT) disease affect the sensory nerves as well as motor neurons. CMT diseases are composed of a heterogeneous group of diseases. They are characterized by symptoms such as muscle weakness and wasting.

Symptom Perception, Evaluation, Response to Symptom, and Delayed Care Seeking in Patients With Acute Heart Failure: An Observational Study.

Background: Exacerbation of heart failure (HF) requires early intervention to prevent hospital admission and to reduce mortality. Early care seeking requires that patients perceive symptoms, accurately evaluate perceived symptoms, and respond appropriately. How perception, evaluation, and response to symptoms are associated with delay in seeking care for worsening symptoms has rarely been studied.

A hydrogen bonded molecular capsule versus a 3D network of tripodal organopolysilanols.

1,3,5-Triethylbenzene based tripodal trisilanols were synthesized. The X-ray crystal structures of trisilanols showed capsule formation as well as non-capsular network formation using silanol hydrogen bonds. The (1)H NMR and ESI-mass spectroscopy experiments for solution state binding supported encapsulation of the halide ions in the cavity of the molecular capsule with a C3 symmetry.

[Selection of an optimum solvent for administration of oxinorm powder through a tube].

Oxinorm powder is a rapid-release preparation of oxycodone hydrochloride for oral administration recently marketed for the first time in Japan. Administration of a powdered drug through a nasal tube is known to involve the risk of tube obstruction by the drug. For narcotic preparations like oxinorm powder, it is desirable from the perspective of drug control, that the drug administered be unlikely to remain in the cup, syringe or catheter used, and that the drug be dispensable in precise amounts.
