Article Abstract
The dysregulation of the autonomic nervous system (ANS) activity notably contributes to the onset and progression of numerous diseases, including lifestyle-related and psychiatric disorders. This necessitates the development of effective nonpharmacological methods for regulating ANS function for therapeutic purposes and disease prevention. This study examined how the presence or absence of the inaudible high-frequency component (HFC) of sounds-which activates deep-brain structures-affects the ANS regulatory function. Under the N-back task condition, which requires concentration, exposure to sounds with HFC resulted in significantly higher sympathetic and parasympathetic nervous activities compared to sounds without HFC. Conversely, under the relaxation condition, the sounds with HFC significantly suppressed sympathetic nervous activity relative to sounds without HFC. Therefore, sounds with HFC may flexibly adjust the sympathetic and parasympathetic nervous activities based on situational demands.

Although stress significantly impacts on various metabolic syndromes, including diabetes mellitus, most stress management techniques are based on psychological and subjective approaches. This study examined how the presence or absence of the inaudible high-frequency component (HFC) of sounds, which activates deep-brain structures, affects glucose tolerance in healthy participants using the oral glucose tolerance test (OGTT). Sounds containing HFC suppressed the increase in glucose levels measured by incremental area under the curve in the OGTT compared with the otherwise same sounds without HFC.

Difluoromethane (HFC-32, DFM), with a global warming potential (GWP) of 677, is of interest as a pure refrigerant and as a component in low-GWP refrigerant mixtures. Additionally, difluoromethane has recently been identified as a safe, liquefied-gas electrolyte material in batteries. Using state-of-the-art instruments for measurements, this paper presents new liquid-phase speed of sound and vapor-phase density data for difluoromethane.

Article Synopsis
- Carbapenem-resistant Klebsiella pneumoniae (CRKP) is a major global health threat, prompting a study to analyze its bacterial traits and patient outcomes across various countries.
- The CRACKLE-2 study recruited 991 hospitalized patients from 71 hospitals in countries like the USA, China, and Argentina, focusing on cultures positive for CRKP and measuring clinical outcomes, including 30-day mortality rates.
- Results showed that patients from the USA were generally sicker and had more pre-existing health issues compared to those from China and South America, with minimal genetic variation in CRKP observed within countries.
Frequencies of inaudible high-frequency sounds differentially affect brain activity: positive and negative hypersonic effects.

The hypersonic effect is a phenomenon in which sounds containing significant quantities of non-stationary high-frequency components (HFCs) above the human audible range (max. 20 kHz) activate the midbrain and diencephalon and evoke various physiological, psychological and behavioral responses. Yet important issues remain unverified, especially the relationship existing between the frequency of HFCs and the emergence of the hypersonic effect.
