Brain ideal midline estimation is vital in medical image processing, especially in analyzing the severity of a brain injury in clinical environments. We propose an automated computer-aided ideal midline estimation system with a two-step process. First, a CT Slice Selection Algorithm (SSA) can automatically select an appropriate subset of slices from a large number of raw CT images using the skull’s anatomical features. Next, an ideal midline detection is implemented on the selected subset of slices. An exhaustive symmetric position search is performed based on the anatomical features in the detection. In order to enhance the accuracy of the detection, a global rotation assumption is applied to determine the ideal midline by fully considering the connection between slices. Experimental results of the multi-stage algorithm were assessed on 3313 CT slices of 70 patients. The accuracy of the proposed system is 96.9%, which makes it viable for use under clinical settings.

本文梳理了两个世纪以来都市理论的主流思潮和长期争论。作者首先指出都市理论诞生于18世纪末至19世纪初,这与欧洲和北美洲的现代都市化进程基本同步。继而概述了都市理论的两大传统:一是芝加哥学派以建模和测量为主的定量研究和实证主义传统,二是法兰克福学派以马克思主义政治经济学为基础的文化批评传统,这两个传统影响了后来的都市地理学、洛杉矶学派、全球城市研究和都市文化研究等。此外,本文着重介绍了女性主义、后殖民主义和后结构主义与都市理论的交叉融合,认为这种“混合搭配”的方法是当代都市理论的特征之一,它质询了不同理论传统的矛盾,汲取了众多学科的批评经验,加深了我们对城市的理解。

Dentin matrix protein 1（DMP1） is essential to odontogenesis. Its mutations in human subjects lead to dental problems such as dental deformities, hypomineralization and periodontal impairment. Primarily, DMP1 is considered as an extracellular matrix protein that promotes hydroxyapatite formation and activates intracellular signaling pathway via interacting with avb3 integrin. Recent in vitro studies suggested that DMP1 might also act as a transcription factor. In this study, we examined whether full-length DMP1 could function as a transcription factor in the nucleus and regulate odontogenesis in vivo. We first demonstrated that a patient with the DMP1M1 V mutation, which presumably causes a loss of the secretory DMP1 but does not affect the nuclear translocation of DMP1, shows a typical rachitic tooth defect. Furthermore, we generated transgenic mice expressingNLSDMP1, in which the endoplasmic reticulum（ER） entry signal sequence of DMP1 was replaced by a nuclear localization signal（NLS） sequence, under the control of a 3.6 kb rat type I collagen promoter plus a 1.6 kb intron 1. We then crossbred theNLSDMP1 transgenic mice with Dmp1 null mice to express the NLSDMP1 in Dmp1-deficient genetic background. Although immunohistochemistry demonstrated thatNLSDMP1 was localized in the nuclei of the preodontoblasts and odontoblasts, the histological, morphological and biochemical analyses showed that it failed to rescue the dental and periodontal defects as well as the delayed tooth eruption in Dmp1 null mice. These data suggest that the full-length DMP1 plays no apparent role in the nucleus during odontogenesis.

Objectives: To specify the epidemiological and clinical profile of the patients, to determine the methods of management and to evaluate the maternal and perinatal prognosis in the association of arterial hypertension and pregnancy (HTA) at the Institute of Social Hygiene of Dakar. Material and Methods: This was a retrospective, descriptive and analytical study on the management of the association of hypertension and pregnancy in the maternity ward of the Institute of Social Hygiene of Dakar between January 1st, 2019 and on December 31st, 2020. Results: During the study period, we recorded 326 cases of hypertension associated with pregnancy among the 4290 pregnant women, i.e. a frequency of 7.6%. The epidemiological profile of the patients was that of a woman with an average age of 29, nulliparous (48.2%), married (99.1%), at a low socioeconomic level (61.3%) and with a personal history preeclampsia (14.4%). Most patients (83.1%) were evacuated or referred with pre-ec- lampsia as the main reason (40.8%). The average gestational age was 37 weeks of amenorrhea (SA) with extremes of 20 SA 6 days and 41 SA 5 days. Term pregnancies were the most represented (76.7%). Prenatal follow-up (CPN) was carried out in 319 patients (97.8%) with an average number of CPN of 3 and extremes of 1 and 9. Severe diastolic and severe systolic hypertension concerned respectively 19.3% and 16, 9% of patients. One hundred and eighty patients (55.2%) presented with oliguria. Strip albuminuria was performed in 235 patients (72.1%). It found 3 or more crosses in 38.3% of cases. We recorded 53 cases of anemia (16.3%), 16 cases of significant proteinuria (5%), hepatic cytolysis in 22 patients (6.7%), thrombocytopenia in 37 patients (11.3%), and 43 cases of hyperuricaemia (13.2%). Obstetric ultrasound found 36 cases of severe oligohydramnios (11%), 8 twin pregnancies (2.4%) and an umbilical Doppler anomaly in 10 patients (3.1%). Pre-eclampsia was the most common clinical form
