Analysis of Pretreatment Factors Associated with Stability in Early Class III Treatment

BACKGROUND: The purpose of this study was to identify pretreatment factors associated with the stability of early class III treatment, since most orthodontists start the treatment with their uncertain hypotheses and/or predictions. Subjects consisted of 75 patients with a class III skeletal relationship (ANB \u3c 2° and overjet \u3c 0 mm) who had been consecutively treated with rapid maxillary expansion and facemask and followed until their second phase treatment. The patients were divided into two groups according to whether they showed relapse in follow-up. The stable group maintained their positive overjet (n = 55), and the unstable group experienced relapse with a zero or negative overjet (n = 20). Two general, three dental, and 13 cephalometric pretreatment factors were investigated to determine which factors were associated with stability. RESULTS: Sex, pretreatment age, and anteroposterior functional shift, which were hypothesized as associated factors, were not related to the stability of early class III treatment. Significant differences were detected between the two groups in the horizontal distance between the maxillary and mandibular molars in centric relation. Cephalometric variables, such as the mandibular length (Ar-Me), Wits appraisal, SN to ramus plane angle (SN-Rm), gonial angle, incisor mandibular plane angle (IMPA), and Frankfort plane to mandibular incisor angle (FMIA) showed significant differences between the groups. The horizontal distance was the most influential factor by logistic regression analysis. CONCLUSIONS: Hypothesis (related to sex, age, functional shift) were rejected. Several cephalometric factors related to the mandible were associated with stability. The horizontal distance between the maxillary and mandibular molars in centric relation was the best predictor of early class III treatment relapse

Spontaneous regression of small cell lung cancer combined with cancer associated retinopathy

Spontaneous regression (SR) is defined as the complete or partial disappearance of disease without anticancer treatments. We report a case of SR of small cell lung cancer (SCLC) combined with cancer associated retinopathy (CAR). A 65-year-old woman was admitted to our hospital to examine abnormal shadows of the lung with visual loss. She was diagnosed with SCLC associated with CAR. Subsequent chest X-ray and CT scan showed partial regression of both primary tumor and lymph node metastasis without anticancer treatment. Recoverin antigen was present on the tumor cells and anti-recoverin antibody was observed in the patient's serum. Activation of recoverin-specific antitumor cytotoxic T lymphocyte (CTL) was observed in this patient. SCLC was considered to reduce spontaneously by the activation of recoverin-specific antitumor CTL. To the best of our knowledge, this is the first report of SR in SCLC combined with CAR.

X-Ray Expanding Features Associated with a Moreton Wave

We report on the simultaneous observation of a Moreton wave in Hα and two kinds of coronal expanding features in soft X-rays near the solar limb. We consider the faster X-ray feature and the slower one as being an ``X-ray wave'' and ``ejecta'', respectively. The chromospheric Moreton wave propagated on the solar disk at a speed of 1040±100kms[-1] , whereas the coronal X-ray wave propagated outside of the disk toward the outer corona at 1400±250kms[-1]. We identified the X-ray wave as MHD fast-mode shock. The fast-mode Mach number (Mf) of the X-ray wave was also estimated to be about 1.13-1.31, which decreases during propagation. The timing when the Mf became ``1'' is consistent with that of the disappearance of the Moreton wave. Moreover, we discuss the 3-dimensional structure of the shock wave and the relation between the shock wave and the ejecta (and Hα filament eruptions)

Filament oscillations and Moreton waves associated with EIT waves

ABSTRACT In this paper we compare EUV Imaging Telescope (EIT) waves with simultaneous phenomena seen in H in order to address the question of what an EIT wave is. We surveyed the events associated with solar flares larger than GOES M-class in 1999-2002. The H data are taken with the Flare-monitoring Telescope (FMT) at the Hida Observatory of Kyoto University. Among 14 simultaneous observations of EIT waves and H, 11 were found to have filament eruptions, three were associated with Moreton waves, and one was found to have only filament oscillations. This shows that we cannot see clear wave fronts in H even if EIT waves exist, but that it is possible to recognize invisible waves by means of filament oscillations. The nature of filament oscillations and Moreton waves associated with EIT waves is examined in detail, and it is found that the filament oscillations were caused by EIT waves

OmpA-like protein is a major glycoprotein isolated by WGA affinity chromatography.

<p>(a) Lectin-binding glycoproteins were isolated from wild-type (WT) <i>T</i>. <i>forsythia</i> and a <i>T</i>. <i>forsythia</i> deletion mutant that lacked OmpA-like protein (Δ<i>1331</i>) using WGA affinity chromatography. Isolated proteins were subjected to SDS-PAGE. The gels were stained with CBB. M, molecular marker; P, whole cell lysate prior to application to the WGA affinity column; B, proteins bound to the WGA column; arrowhead, OmpA-like protein.
