Rodent study suggests that interleukin (IL)-15 administration enhances insulin sensitivity. Although it is well known that circulating levels of typical inflammatory markers (C-reactive protein [CRP] and IL-6) are positively associated with homeostasis model assessment-insulin resistance (HOMA-IR), there are no studies investigating the associations of other inflammatory markers including IL-15 with peripheral/hepatic insulin sensitivity in humans. The current study aimed to examine the relationship between the levels of adiopokines or inflammatory cytokines and insulin sensitivity in 8 healthy middle-aged men. Circulating levels of 10 insulin sensitizing adipokines or inflammatory cytokines (total adiponectin [APN], high molecular weight adiponectin [HMW-APN], IL-4, IL-5, IL-6, IL-8, IL-15, interferon [IFN]-γ, tumor necrosis factor [TNF]-α, and TNF-β) were measured. A stable-labeled frequently sampled intravenous glucose tolerance test was performed to assess peripheral () and hepatic () insulin sensitivity estimated by 2-compartment minimal model. The levels of 3 inflammatory cytokines (IL-4, IL-6, and IL-15) were significantly and inversely correlated with either and . The association between IL-15 and either or was significant even after adjusting for age and percent body fat (p < 0.01). The current study showed a possible inverse association between serum IL-15 level and peripheral/hepatic insulin sensitivity in healthy middle-aged males, independent of percent body fat;this association in humans warrants further study.

Journal of Energy and Power Engineering 2012年第3期6卷 353-360页

Various ocean energy technologies have been developed that harness several kinds of renewable energy resources of the ocean. However, these technologies suffer from problems such as high construction and maintenance costs, restrictive installation requirements and damage by extraordinary weather conditions. In this paper, we propose a lightweight and FPGD (flexible power generation device) that overcomes these problems. The FPGD essentially consists of piezoelectric films and silicon rubber. Because the FPGD is small and flexible, it is anticipated to efficiently convert fluid energy into electrical energy even when the fluid energy is low. We perform several experiments to confirm the effectiveness of the FPGD and we discuss the results.

AIM: To quantitatively evaluate the impact of smoking on tooth ***: We performed a Pub Med search to identify published articles that investigated the risk of tooth loss by smoking, from which RRs and their variance with characteristics of each study were extracted. The random-effects models were used to derive a pooled effect across studies. Potential sources of heterogeneity on the characteristics of the study and their influence on the pooled effect size were investigated using metaregression models. RESULTS: We identified 24 studies containing a total of 95973 participants for analysis. The pooled RR of ever-smokers compared with never- smokers was 1.73(95%CI: 1.60-1.86, P < 0.001). In meta-regression analysis, only the mean age of participants alone was identified as a statistically significant source of heterogeneity. The effect of smoking on tooth loss was stronger when the mean age of study participants was higher, indicating possible enhancement of tooth loss due to aging by smoking. RR was significantly lower in former smokers(1.49, 95%CI: 1.32-1.69, P < 0.001) than in current smokers(2.10, 95%CI: 1.87-2.35, P < 0.001), indicating the substantial benefit of smoking cessation for reducing the risk of tooth ***: Smoking is an independent risk factor for tooth loss regardless of many other confounders. Smoking cessation may attenuate this effect.

Open Journal of Pediatrics 2018年第4期8卷 324-333页

We previously investigated the thickness of the epidermis and lengths from the skin surface to the muscle fascia and bone based on measurements taken from the ultrasonic echograms of Japanese infants aged 2, 3, 4, 5, 6, and 12 - 15 months. The appropriate needle length for intramuscular injection was 16 mm (5/8 inch) in Japanese infants at any age and site. In the present study, we examined these lengths in 21 infants with physical growth from 2 to 15 months. Average height increased from 58.5 to 73.6 cm and average body weight from 5835 to 9226 g until 15 months. The circumference of the thigh increased from 22.3 cm at 2 months to a maximum of 25.9 cm at 6 months, while that of the deltoid area was 15.2 cm at 2 months and 15.9 cm at 6 months. Subcutaneous mass (length from the skin surface to the muscle fascia) at the thigh increased between 3 and 4 months and decreased at 12 - 15 months and showed good relationship to the circumference of the thigh. Subcutaneous mass at the center of the deltoid area showed the same size until 6 months. Muscle mass (lengths from the muscle fascia to the bone) at thigh and deltoid areas remained the same until 6 months. Ultrasonic echogram is an effective tool for evaluating subcutaneous and muscle mass in young infants.

Appropriate Needle Lengths Determined Using Ultrasonic Echograms for Intramuscular Injections in Japanese Infants

引用

Open Journal of Pediatrics 2016年第2期6卷 163-170页

作者： Tetsuo Nakayama Urara Kohdera Motoko Fujino Toshihiro tanaka keitaro Yatabe Tomoyuki Hashiguchi Tomohide Sato Minoru Kino Kitasato Institute for Life Sciences Laboratory of Viral Infection I Tokyo Japan Department of Pediatrics Nakano Children’s Hospital Osaka Japan Department of Pediatrics Saiseikai Central Hospital Tokyo Japan Department of Pediatrics Shizuoka Kosei Hospital Shizuoka Japan Department of Clinical Development & Medical Affairs Japan Vaccine Co.

Adjuvanted vaccines are recommended for administration through an intramuscular route. The Centers for Disease Control and Prevention (CDC) has recommended the anterolateral thigh using a 22 - 25-G 25-mm (1 inch) needle for infants, injected at a 90° into the skin surface, and using a 16 mm (5/8 inch) for newborns. Appropriate needle lengths may differ depending on racial backgrounds. In the present study, the thickness of the epidermis and lengths from the skin surface to the muscle fascia and bone were measured using ultrasonic echograms in order to determine suitable needle lengths for Japanese infants aged 2, 3, 4, 5, 6, and 12 - 15 months old. The thickness of the epidermis was 1.44 - 1.54 mm (95% CI), and the lengths from the skin surface to the muscle fascia and bone were 11.52 - 12.28 mm (95% CI), and 25.66 - 26.93 mm (95% CI), respectively, at the anterolateral thigh. At the center of the deltoid muscle, skin thickness was similar to that at the thigh, furthermore the lengths from the skin surface to the muscle fascia and bone were 8.49 - 9.10 mm (95% CI), and 17.38 - 18.31 mm (95% CI), respectively. The lengths from the skin surface to the muscle fascia and bone were 1 - 2 mm shorter in 2-month-old infants than those in older generations. Therefore, the appropriate needle length for intramuscular injections in Japanese infants was 16 mm (5/8 inch) at any age and sites, and with 25 mm (1 inch) needles at a 90° angle being associated with the risk of over-penetration.
