The human skin serves as the primary barrier against environmental stressors. This necessitates adequate skincare to prevent or slowdown various skin conditions such as aging, dryness of the skin, and skin blemishes. Cosmetic products that possess both antioxidant and antibacterial properties are essential in combatting skin conditions such as acne, which is an inflammatory bacterial infection often caused by Propionibacterium acne, Staphylococcus epidermidis, and Staphylococcus aureus. 1 Extensive research has explored the pharmacological and therapeutic potentials and efficacy of herbal remedies. [2] [3] [4] [5] [6] Green coffee, derived from unroasted coffee beans (Coffea canephora var. Robusta), exhibits higher antioxidant activity compared to its roasted counterpart. This variation may be attributed to the higher concentration of antioxidants, particularly chlorogenic acid in the green coffee extract. 7, 8 In addition, coffee extract contains phenolic and flavonoid compounds that possess antibacterial effects.

Abstract This paper presents a room temperature bonding technique of glass substrates with a transparent bonding interface. As a room temperature bonding method, surface activated bonding (SAB) is applied for the bonding of glass using Si intermediate layer. However, the bonding interface is colored by the deposited Si layers, which leads to lower applicability to optical devices. In this study, a new concept of SAB is developed using aluminum oxide intermediate layer. Glass substrates are successfully bonded at room temperature via the aluminum oxide intermediate layers activated by Ar ion beam irradiation, showing a bond strength of 1.32 J m−2. It is also shown that the optical characteristics at the interface such as transparency and reflectance are not degraded, while the bonding interface of the SAB using Si intermediate layer deteriorates. The XPS and STEM‐EDX analyses indicate that the bonding is achieved through the amorphous and O‐deficient aluminum oxide interface. This technique will provide a transparent interface for glass bonding by a room temperature process, which is highly desired in optical device fabrication.

Diffuse interstellar bands (DIBs) are an enigmatic set of interstellar absorption features, observed at optical and near infrared wavelengths in the spectra of reddened stars in our Galaxy also in other galaxies. Identifying the carriers of DIBs has been a longstanding challenge and is still very much a work in progress. In recent years, surveys of DIBs have been conducted, but mostly focus on strong bands. In this work, we extracted and measured DIBs recorded in the high-resolution stellar spectra of ε Auriga (ε Aur) and IQ Per observed by using Gunma Astronomical Observatory Echelle Spectrograph (GAOES) (spectral resolution R∼65000). Observations were aimed at obtaining high resolution spectra of double-lined detached eclipsing binaries. For each selected DIB, we performed spectral fitting of a combination of a smooth stellar continuum (polynomial function), an empirical DIB model, and a synthetic telluric transmission. The high-quality data allow us to measure not only strong and well-known DIBs, but also weaker DIBs.

Transsphenoidal surgery requires the surgeon to insert surgical instruments through the nasal cavity to the brain tissue and to perform fine manipulations. Introducing surgical robots into transsphenoidal surgery potentially provides various benefits such as reducing hand tremor and increasing precision, while the lack of haptic feedback remains as one of the main technical challenges. To overcome this issue, we introduce a miniaturized (3×2×0.5mm) force sensor that can be introduced into surgical robots. In this paper, we introduce the overview of the structure and its preliminary evaluations.

Tlie Japanese X-ray astronomical satellite Suzaku launched in July 2005 is equipped with two kinds of X-ray instruments for the wide-band spectroscopy. The X-ray CCD cameras (XIS) cover 0.3 to 12keV with the energy resolution of 120eV at 6keV. The Hard X-ray Detector (HXD) consisting of well-type phoswitch counters covers 40-600)keV. With these instruments, we organized a team for quick follow-up observations of gamma-ray bursts, aiming to observe the afterglow phase transition and to search for spectral features with the wide band X-ray instruments.

This study was performed to determine the complications occurring during retrograde percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) based on analysis of the multicenter, prospective, nonrandomized Retrograde Summit registry. Retrograde PCI for CTO has improved treatment success rates, but several complications related to the retrograde approach have been reported, including collateral channel injury and donor artery injury due to their use as retrograde roots. This registry included data from 1,166 patients who underwent retrograde PCI for CTO in 28 Japanese centers between January 2009 and December 2011. Overall procedure success and retrograde procedure success were achieved in 985 (84.5%) and 838 (71.9%) of the 1,166 patients, respectively. In-hospital major adverse cardiac and cerebrovascular events (MACCE) occurred in 18 (1.5%) of the 1,166 patients. With regard to complications related to the retrograde approach, channel injury occurred in 111 (9.5%) of the 1,166 patients, but treatment was required in only 24 (2.1%) patients and subsequent cardiac tamponade occurred in only 4 (0.3%) patients. Donor artery problems occurred in only 10 (0.9%) of the 1,166 patients. In sub-analysis regarding the types of collateral channels, the septal channel was significantly safer than epicardial channel because of the lower frequency of non-Q-wave myocardial infarction (non-QMI) and channel injury requiring treatment. The MACCE rate during retrograde PCI for CTO determined from the Retrograde Summit registry was low and the frequency of complications related to the retrograde approach was acceptable. © 2015 Wiley Periodicals, Inc.

Background: The role of plaque morphology, composition, and spatial distribution in plaque rupture and coronary occlusion in patients suffering acute myocardial infarction (AMI) needs clarification. Using color-mapping iMAP intravascular ultrasound (iMAP-IVUS), we examined culprit lesions to clarify plaque morphology, plaque composition and spatial distribution of the sites of potential vulnerability. Methods: Sixty-eight culprit lesions in 64 consecutive AMI patients who underwent angiography and IVUS examinations before intervention were analyzed. Plaque morphology and composition were quantified and compared between totally occlusive (TO) (n=42) and non-TO lesions and between ruptured (n=27) and non-ruptured lesions. Results: Both the length and plaque burden (PB) of TO lesions were greater than those of non-TO lesions (54.16 ± 21.16 mm versus 40.01 ± 17.51 mm, respectively, p = 0.006; PB: 0.63 ± 0.07 versus 0.58 ± 0.08, respectively, p = 0.02). Ruptured lesions were coincident with significant vessel remodeling (vessel volume: 745.5 ± 41.3 mm3 versus 635.7 ± 33.5 mm3, p = 0.04) and plaque volume (450.0 ± 23.8 mm3 versus 387.7 ± 19.3 mm3, p = 0.046). Also, the lipidic volume was greater (57.6 ± 3.8 mm3 versus 46.9 ± 3.1 mm3, p = 0.03) and the necrotic volume (152.6 ± 12.1 mm3 versus 125.8 ± 9.8 mm3, p = 0.09) tended to be greater in ruptured lesions. Examination of the longitudinal distribution of the sites of recognized vulnerability, i.e., maximum necrotic area (maxNA), maximum PB (maxPB) and most severely narrowed (minimal luminal area, MLA) revealed that most maxNA sites and maxPB sites were proximal to MLA sites. Ruptures usually occurred very close to maxNA sites (average distance: 0.33mm, 44% were proximal to, 26% overlapped and 30% were distal to a maxNA site) and proximal to maxPB and MLA sites. Conclusion: Plaque morphology and composition play critical roles in plaque rupture and coronary occlusion. The maxNA sites are the sites most likely to rupture, and most ruptures occur proximal to maxPB sites and MLA sites.
