Adults (aged 15–75 years) GPP, total skin score (overall erythema area, area pustules, edema area) 3 or more, pustules (skin score, ≥1) based on 2014 Dermatological Association severity index GPP were enrolled. The primary end‐point was...

Clock genes that pleiotropically control circadian rhythm and the time of mating may cause allochronic reproductive isolation in melon fly Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae). Flies with a shorter period (ca. 22 h locomotor activity rhythm) mated 5 earlier day than those longer 30 h). Mate-choice tests demonstrated significant pre-mating between populations short long periods. Pre-mating did not occur when was synchronized two by photoperiodic controls, indicating is...

This paper presents the first case of successful eradication a Coleoptera pest species over wide area using combination male annihilation technique (MAT) and sterile insect (SIT) application. The sweet potato weevil, Cylas formicarius, is one most destructive widely distributed pests potato, Ipomoea batatas. A project to eradicate it was launched in 1994 on Kume Island, Okinawa Prefecture, Japan. MAT application used from November January 1999 reduce density wild populations. distribution...

Due to the excessive increase in environmental costs of nonrenewable energy resources, there have been government legislation, policies, and new technologies control carbon emissions. The renewable resources requires strategies for operation management electricity. This paper presents power flow coloring system, which gives a unique ID each between specific source load. It allows us design multiple patterns distributed fluctuating sources loads taking into account availability, cost, dioxide...

This phase 3, multicenter, open-label single-arm study evaluated adalimumab (ADA) in Japanese patients with moderate to severe hidradenitis suppurativa (HS). Fifteen received ADA 160 mg s.c. at week 0, 80 2 and 40 4 every thereafter. At any time after 52, were given the option receive other or remain on week.

Abstract Background subtraction is widely used as an effective method for detecting moving objects in a video image. However, background requires prerequisite that image variation cannot be observed, and the range of application limited. Proposed this research paper by using can applied to cases which has varied due varying illumination. This based on two object detection methods are different lines thinking. One compares observed invariant features The other estimates illumination...

Abstract An eradication project against the sweetpotato weevil, Cylas formicarius ( Fabricius) (Coleoptera: Brentidae), one of most important pests sweet potato in world, was initiated Oct. 2007 on Tsuken Island, Okinawa Prefecture, Japan. The sterile insect technique (SIT) and male annihilation (MAT) were employed as main control measures to suppress ultimately eradicate wild populations by impeding normal mating. In addition, two monitoring methods (host plant survey trap survey) used...

Abstract The efficacy of sterile insect technique (SIT) depends on successful mating released males with wild females. If the time in a day mass-reared and differs from those females, efficiency SIT decreases. Therefore, understanding molecular mechanisms controlling target pests is particularly important for SIT. period (per) gene, which has been considered as key clock gene melon fly, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae), was cloned two strains having different times...

2-(3′,5′-Di-tert-butyl-2′-hydroxyphenyl)-5-chlorobenzotriazole (DBHCB) is widely used as an ultraviolet absorber. Previously, we showed that male rats had more than a 100 times higher susceptibility to the toxic effects of DBHCB females. In order investigate role sex steroids in mediation this gender-related difference, (0 or 250 mg/kg/day) was given and female young intact castrated by gavage for 28 days current study. rats, relative liver weight increased two control males, while rate...

The were asymptomatic but increased gradually, which brought patient to our hospital. On initial examination, we noticed 5 mm × 15 mm, round or oval, light dark brown keratotic papules chest abdomen extremity. aligned in an S‐shaped line a straight Clinical histopathological findings led diagnosis seborrheic keratosis that followed Blaschko's lines.

This paper proposes an effective method for compensating inter-reflection in immersive projection displays (IPDs). Because IPDs project images onto a screen, which surrounds viewer, we have perform out both geometric and photometric corrections. Our compensates on the screen. It requires no special device, approximates diffuse specular reflections screen using block-based calibration.

We have developed a high-precision method that selects an appropriate model of video image in order to track unknown face front large display. Currently, Active Appearance Models (AAMs) are used non-rigid objects, such as faces, because the models efficiently learn correlation between shape and texture. The problem with AAM is when it tracks face, excessive training data increases tracking errors there intermediate size beyond which reduction fitting performance outweighs gains from any...

In our previous toxicity studies using young rats, we showed that an ultraviolet absorber, 2-(2'-hydroxy-3',5'-di-tert-butylphenyl)benzotriazole (HDBB), principally affected the liver, and male rats had nearly 25 times higher susceptibility to toxic effects than females. present study, of HDBB was investigated in preweaning rats. administered by gavage female CD(SD) from postnatal days 4 21 at a dose 0, 0.1, 0.5, 2.5, or 12.5 mg/kg/day. No substance-related deaths, clinical signs toxicity,...
