Sexual dimorphism in teeth: discriminatory effectiveness of permanent lower canine size observed in a XVIIIth century osteological series

Recent studies have shown that the most dimorphic tooth is the mandibular canine. We have carried out a study on a random sample of 146 skeletons dating from the plague outbreak in Marseilles (1722). We studied 1284 maxillary and 1432 mandibular permanent teeth. Sexual dimorphism was tested on 89 individuals. We selected a set of four dental indices and calculated the dimorphism percentage by ratio expression male/female. Dimorphic ranking was made, by allotting the first rank to the tooth presenting the highest dimorphism and the last rank to the one presenting the lowest ratio. Comparisons of means were made on both sexes (sex determined by post-cranial data) through a Student's test (t-test). We noted that lower canines and lateral incisor are the most interesting teeth in the dimorphic dental determination. The lower index presented the highest relative risk with RR = 1.56 [1.04-2.32]. In 58% of the cases, the lower dental index enabled a correct sex determination (determined on the basis of the post-cranial skeleton). These results showed the existence of a relative dental dimorphism (male > female mesiodistal diameters) with humans. In conclusion, this method, using dental measurements, may be used as an additional technique to determine sex on fragmentary adult skeletons, immature material, missing pieces or ambiguities on post-cranial remains.     

我国现阶段私营企业融资难问题的成因及对策

我国私营经济在国民经济中发挥了十分重要的作用。然而,由于私营企业自身缺陷的内部原因以及金融体制和社会环境等外部原因,使得其融资比较困难,进而阻碍了其进一步的发展。为此,一方面,私营企业自身要逐步完善现代化经营和管理,为融资创造有利条件;另一方面,要培育和完善私营企业的外部融资环境,拓宽私营企业的融资渠道。     

小机会孕育大事业

你认为自己已经具备了成为企业家的所有条件。你已经阅读了别人的成功故事，他们大获成功，这令你感到不安。你工作得很出色，人们总是说你前途无量，但是．你已经厌倦了接受平庸的人发出的平庸命令。而凡，为什么所有聪明的想法都是你的，但荣誉却总被别人得到？什么时候你能得到一次大幅提升——有可观的工资上涨．得到期权奖励和巨额奖金呢？“再等等，”他们总是说。“再等等。”是自己当老板的时候了。然而，如果你现在的工作舒适而安逸，每月定期领取工资，在现代化的办公室里工作．有一个高效率的秘书，还有一种在基础稳同的大公司工作的安全感．那么．住你辞上这份好工作之前，我有些告诫的话给你。     

维护国家主权是实现人权的根本保障

某些西方国家及其部分学者自第二次世界大战结束以来,在主权与人权关系问题上,提出了诸如“人权高于主权”、“人权无国界”、“主权不属内政”、“主权过时”和新“人道主义干涉”等所谓新理论。这些理论蓄意歪曲并从根本上颠倒了国家主权与人权的关系,违反了《联合国宪章》和国际人权文书的规定,也不符合国际人权实践。     

Effect of toluene inhalation on astrocytes and neurotrophic factor in rat brain

Toluene, an abused substance in Japan, is a neurotoxic chemical that has been shown to have neurobehavioral and electrophysiological effects. In previous work, both acute and chronic effects of toluene on cells have been studied extensively. However, although glial cells are thought to play an important role in the survival of neurons in the brain, the effect of toluene on glial cell function has not yet been characterized. To elucidate this, the effect of toluene inhalation on astrocytes in rat brain was examined. Toluene exposure (1500 ppm for 4 h on 4-10 days) augmented glial fibrillary acidic protein (GFAP) immunoreactivity, particularly in the hippocampus and cerebellum. Quantitative analysis showed that toluene inhalation markedly enhanced GFAP expression in the hippocampus and cerebellum. In both regions, proliferating cell nuclear antigen (PCNA) showed no obvious changes, but glutamine synthetase (GS)-immunoreactive cells were markedly increased by toluene exposure. Thus, the elevation of GFAP expression was induced by astrocyte activation rather than by cell proliferation. If toluene exposure activates astrocytes, astrocytes may play a role in the neurophysiological changes observed in toluene intoxication. A neurotrophic factor, basic fibroblast growth factor (b-FGF) was observed immunohistochemically in the capillary vessel walls in the hippocampus and the cerebellum of toluene-intoxicated rats. Basic-FGF may have induced GFAP expression both in the hippocampus and the cerebellum. So, other neurotrophic factors may affect the difference of GFAP elevation between the hippocampus and the cerebellum. These differences may relate to neurobehavioral function of each brain part after toluene exposure.
