Food properties modulate activities in posterior parietal and visual cortex during chewing.

Cross-modal interactions between sensory modalities may be necessary for recognition of chewing food by the invisible oral cavity to avoid damaging the tongue and/or oral mucosa. The present study used functional near-infrared spectroscopy to investigate whether the food properties hardness and size influence activities in the posterior parietal cortex and visual cortex during chewing performance in healthy individuals. It was found that an increase in food hardness enhanced both posterior parietal cortex and visual cortex activities, while an increase in food size enhanced activities in the same regions.

Utility of lymphocyte-to-monocyte ratio and pretreatment tooth extraction in intra-arterial chemoradiotherapy for oral cancer to prevent osteoradionecrosis of the jaw.

The objective of this study was to evaluate the utility of inflammation-based prognostic scores (IBPS) in predicting ORN among patients undergoing superselective intra-arterial chemoradiotherapy (SSIACRT). This retrospective cohort study examined the medical records of 54 patients with advanced oral cancer (stage 3 or 4) treated with SSIACRT. The predictor variable was IBPS.

An ultra-short-period super-Earth with an extremely high density and an outer companion.

We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d.

Cross-modal representation of chewing food in posterior parietal and visual cortex.

Even though the oral cavity is not visible, food chewing can be performed without damaging the tongue, oral mucosa, or other intraoral parts, with cross-modal perception of chewing possibly critical for appropriate recognition of its performance. This study was conducted to clarify the relationship of chewing food cross-modal perception with cortex activities based on examinations of the posterior parietal cortex (PPC) and visual cortex during chewing in comparison with sham chewing without food, imaginary chewing, and rest using functional near-infrared spectroscopy. Additionally, the effects of a deafferent tongue dorsum on PPC/visual cortex activities during chewing performance were examined.

A dodecamethoxy[6]cycloparaphenylene consisting entirely of hydroquinone ethers: unveiling in-plane aromaticity through a rotaxane structure.

[n]Cycloparaphenylenes ([n]CPPs, where n is the number of phenylene groups), consisting of 1,4-linked phenylene unit, have attracted much attention due to their cyclic π-conjugated structures and physical properties. However, functionalizing of the benzene rings of smaller [n]CPPs (n < 7) has been a challenge due to ring strain and steric hindrance of the substituents that hampers their synthesis. Here we show successful synthesis of a new [6]CPP derivative with twelve methoxy groups at the 2,5-positions of all benzene rings by utilizing our developed CPP synthesis method via a macrocyclic gold complex.

The orexin receptor 2 (OX2R)-selective agonist TAK-994 increases wakefulness without affecting cerebrospinal fluid orexin levels in cynomolgus monkeys.

Orexin A (OX-A) and orexin B are neuropeptides produced in orexin neurons located in the lateral hypothalamus that exert multiple biological functions through the activation of orexin receptor 1 (OX1R) and orexin receptor 2 (OX2R) throughout the central nervous system. OX1R and OX2R have distinct functions: OX1R is involved in reward seeking, whereas OX2R has a pivotal role in sleep/wake regulation. OX2R-selective agonists are in development as novel therapeutic agents for the treatment of hypersomnia.

A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067.

Planets with radii between that of the Earth and Neptune (hereafter referred to as 'sub-Neptunes') are found in close-in orbits around more than half of all Sun-like stars. However, their composition, formation and evolution remain poorly understood. The study of multiplanetary systems offers an opportunity to investigate the outcomes of planet formation and evolution while controlling for initial conditions and environment.

A super-massive Neptune-sized planet.

Neptune-sized planets exhibit a wide range of compositions and densities, depending on factors related to their formation and evolution history, such as the distance from their host stars and atmospheric escape processes. They can vary from relatively low-density planets with thick hydrogen-helium atmospheres to higher-density planets with a substantial amount of water or a rocky interior with a thinner atmosphere, such as HD 95338 b (ref. ), TOI-849 b (ref.

Background: Liquid-based cytology (LBC), now used globally for the head and neck region, has been used at our hospital since 2011. This study was designed to analyze the efficacy of LBC with immunocytochemical staining on preoperative diagnosis of salivary gland tumors.

Methods: This retrospective analysis of fine-needle aspiration (FNA) performance for salivary gland tumors was conducted at Fukui University Hospital.

Comparison of Percutaneous Coronary Intervention Procedures and Outcomes for Recent and Acute ST-Elevation Myocardial Infarction.

Although the primary percutaneous coronary intervention (PCI) is an established treatment for acute ST-elevation myocardial infarction (STEMI), relevant guidelines do not recommend it for recent-STEMI cases with a totally occluded infarcted related artery (IRA). However, PCI is allowed in Japan for recent-STEMI cases, but little is known regarding its outcomes. We aimed to examine the details and outcomes of PCI procedures in recent-STEMI cases with a totally occluded IRA and compared the findings with those in acute-STEMI cases.

A temperate Earth-sized planet with tidal heating transiting an M6 star.

Temperate Earth-sized exoplanets around late-M dwarfs offer a rare opportunity to explore under which conditions planets can develop hospitable climate conditions. The small stellar radius amplifies the atmospheric transit signature, making even compact secondary atmospheres dominated by N or CO amenable to characterization with existing instrumentation. Yet, despite large planet search efforts, detection of low-temperature Earth-sized planets around late-M dwarfs has remained rare and the TRAPPIST-1 system, a resonance chain of rocky planets with seemingly identical compositions, has not yet shown any evidence of volatiles in the system.

Clinical Characteristics and Prognosis of Life-Threatening Acute Myocardial Infarction in Patients Transferred to an Emergency Medical Care Center.

Patients with acute myocardial infarction (AMI) triaged as life-threatening are transferred to our emergency medical care center (EMCC). However, data on these patients remain limited. We aimed to compare the characteristics and AMI prognosis of patients transferred to our EMCC with those transferred to our cardiovascular intensive care unit (CICU) using whole and propensity-matched cohorts.

Diurnal Fluctuations of Orexin-A and -B in Cynomolgus Monkey Cerebrospinal Fluid Determined by a Novel Analytical Method Using Antiadsorptive Additive Treatment Followed by Nanoflow Liquid Chromatography-High-Resolution Mass Spectrometry.

Orexin-A (OXA) and -B (OXB) are involved in the regulation of multiple physiological functions including the sleep-wake states; therefore, it is critical to monitor their levels under various conditions. Unfortunately, the widely used radioimmunoassay has insufficient specificity for OXA. Although liquid chromatography-tandem mass spectrometry (LC-MS/MS) has higher specificity for OXA, previously reported OXA levels in human cerebrospinal fluid (CSF) measured using this technique are still inconsistent.

Design and synthesis of 6-methylpyridin-2-one derivatives as novel and potent GluN2A positive allosteric modulators for the treatment of cognitive impairment.
