Long-term interferon therapy is an alternative therapy for patients with chronic hepatitis C who can not tolerate to the combination of pegylated interferon and ribavirin. In 2005, self-injection of interferon for chronic hepatitis C was covered by public health insurance in Japan making the long-term interferon therapy easier to perform. For the safe performance of self-injection, education about knowledge on various adverse effects of interferon, training for actual performance of self-injection, and close contact between the patients and doctors are indispensable. In this review, we briefly summarized why self-injection is needed and how the training for safe self-injection of interferon should be performed.

Purpose: Multiple sclerosis (MS) is a neurological disorder affecting almost 2.8 million people globally, approximately 80-85% of whom have the relapsing-remitting form of the disease (RRMS). There are several autoinjectors available for the administration of injectable disease-modifying therapies for the treatment of MS.

This paper reports an ultra-narrow-linewidth self-injection locked semiconductor laser, which is realized through optical feedback from a high-Q (258 million) Fabry-Perot (FP) cavity constructed with three mirrors, generating an output power of 12 mW. Employing a delay self-heterodyne method based on a signal source analyzer, the phase noise of the laser is -129 dBc/Hz at 100 kHz offset frequency, with an intrinsic linewidth of 3 mHz.

Adrenal crisis is a life threatening complication of adrenal insufficiency (AI). Its treatment is urgent and parenteral hydrocortisone (HC) should be given at 10-15 times physiological doses in this situation. If HC is not available, alternatively prednisolone or methyl prednisolone may be used.
View Article and Find Full Text PDFFrequency-modulated continuous-wave (FMCW) narrow linewidth lasers have served as the cornerstone behind applications such as autonomous driving, wearable technology, virtual reality, and remote sensing mapping. Strongly coherent lasers are typically used for these studies, with a clear demand for linear fast response and wide frequency tuning range. In this paper, profiting from the ultrahigh-quality factor of the crystalline whispering-gallery-mode resonator, by using a self-injection locking mechanism to suppress spontaneous emission noise and improve coherence, sub-kHz linewidth at 450 nm is obtained.

Today's precision experiments for timekeeping, inertial sensing, and fundamental science place strict requirements on the spectral distribution of laser frequency noise. Rubidium-based experiments utilize table-top 780 nm laser systems for high-performance clocks, gravity sensors, and quantum gates. Wafer-scale integration of these lasers is critical for enabling systems-on-chip.
