This study was designed to identify the effects of nicotine on the skeletal and internal organ abnormalities of mice prenatally. Seventy two female mice strain Balb/C were used. Pregnant mice on gestation days (GD) 8, 10, and 12 was injected intraperitoneally with 3, 6, and 12 mg/kg BW nicotine respectively. Control nice was injected by aguabidestylata. On GD 18, and all of pregnant mice were sacrificed, and a half of living fetuses were immersed in Bouin’s solution to observe their internal organs, while another half were immersed in 95 percent ethanol to observed sekeletal malformation using alizarin red S staining. Results were analyzed using SPSS program version 11 for personal computer. The results showed that nicotine caused Skeletal malformation, especially in the sternum when administered on GD 8 and 10, in doses of 3 and 6 mg/kg BW, delayed of ossification was observed in the supraoccipital and sacrocaudal bones on GD 10 and 12 and doses of 12 mg/kg BW, while in the extremitas the malformation was observed in the proximal and medial phalanx both in the fore and hind limb especially on GD 10 and 12, and doses of 6 and 12 mg/kg BW. Nicotine was effects on the brain development especially hydrocephalus was observed on GD 8 and doses 10 and 12 mg/kg BW. Another internal malformation such as ectopic renalis was observed on GD 8 and doses of 3 and 6 mg/kg BW. These finding suggested that nicotine has caused skeletal malformation, brain malformatin and ectopic renalis, when administered in mice prenatally.

<em>The study was aimed to identify the effect of DEET on fetal skeletal abnormalities of Balb/C strain mice. Thirty five female Balb/C strain mice were used in this study. The female mice were mated with male mice used one mating method. Mice in treatment group were administered dermally with 281,25; 562,5 1125 and 2250 mg/kg BW DEET disolved in ethanol at gestation day of 6 to 15, while mice in control were administered with ethanol. Mice in group were repeated seven times. At gestation day 18, the mice were sacrificed and fetal skeletal abnormalities were observed. Bone staining subsequently was done by using Alizarin Red S. Results were analyzed by using SPSS program version 16 personal computer, one way ANOVA and multiple comparison test with significance level of 0,05. Skeletal abnormalities such as supraoccipital, sternal, vertebral, sacrocaudal and phalanx were not found in all doses administered. From these experiment we suggested that DEET has no effects in fetal skeletal abnormalities such as supraoccipital, sternal, vertebral, sacrocaudal and phalanx</em>

Embryonic Brain Development

In mammals, a constant body temperature is an important basis for maintaining life activities. Here, we show that when pregnant mice are subjected to cold stress, the expression of RBM3, a cold-induced protein, is increased in the embryonic brain. When RBM3 is knocked down or knocked out in cold stress, embryonic brain development is more seriously affected, exhibiting abnormal neuronal differentiation. By detecting the change in mRNA expression during maternal cold stress, we demonstrate that Yap and its downstream molecules are altered at the RNA level. By analyzing RNA-binding motif of RBM3, we find that there are seven binding sites in 3′UTR region of Yap1 mRNA. Mechanistically, RBM3 binds to Yap1-3′UTR, regulates its stability, and affects the expression of YAP1. RBM3 and YAP1 overexpression can partially rescue the brain development defect caused by RBM3 knockout in cold stress. Collectively, our data demonstrate that cold temperature affects brain development, and RBM3 acts as a key protective regulator in cold stress.

Teratogenic is an abnormal development on embryo and is the cause of congenital defect or birth defect. This study aims to determine the effect of the addition of Dioscorea alata L. ethanol extracts to the embryo development on pregnant mice whose given orally to 24 mice which divided to 4 treatment groups, they are the normal group (NG) with NaCMC 0.5%; 28 mg/KgBB treatment group; 35 mg/KgBB; 42 mg/Kg BB. The addition of Dioscorea alata L ethanol extracts was done on the sixth day until the 15th day of pregnancy. On the 18th day of pregnancy, Laparaktomi was done to the pregnant mice and the embryo was taken out of the uterus. The observation was done to the fetus numbers, weight weighing of the fetus's body, dan length measurement of the fetus's body. Another observation is the observation of the external organ defect of the embryo. The study results that the addition of Dioscorea alata L ethanol extracts with various doses have no significant effect (P>0.5) to the mice external fetus development. On the examination of the fetus, we can conclude that Dioscorea alata L ethanol extracts don’t give any effect that may cause the defect of the fetus’ external organ.

AbstractReciprocal relationships between organs are essential to maintain whole body homeostasis. An exciting interplay between two apparently unrelated organs, the bone and the brain, has emerged recently. Indeed, it is now well established that the brain is a powerful regulator of skeletal homeostasis via a complex network of numerous players and pathways. In turn, bone via a bone-derived molecule, osteocalcin, appears as an important factor influencing the central nervous system by regulating brain development and several cognitive functions. In this paper we will discuss this complex and intimate relationship, as well as several pathologic conditions that may reinforce their potential interdependence.

Purpose – The purpose of this paper is to outline brain structure and development, the relationship between environment and brain development and implications for practice. Design/methodology/approach – The paper is based on a selected review of the literature and clinical experience. Findings – While genetics determine the sequence of brain maturation, the nature of brain development and functioning is determined by the young child's caregiving environment, to which the developing brain constantly adapts. The absence of input during sensitive periods may lead to later reduced functioning. There is an undoubted immediate equivalence between every mind function – emotion, cognition, behaviour and brain activity, although the precise location of this in the brain is only very partially determinable, since brain connections and function are extremely complex. Originality/value – This paper provides an overview of key issues in neurodevelopment relating to the development of young children, and implications for policy and practice.

Brain Patterning

In vertebrates (deuterostomes), brain patterning depends on signals from adjacent tissues. For example, holoprosencephaly, the most common brain anomaly in humans, results from defects in signaling between the embryonic prechordal plate (consisting of the dorsal foregut endoderm and mesoderm) and the brain. I have examined whether a similar mechanism of brain development occurs in the protostome Drosophila, and find that the foregut and mesoderm act to pattern the fly embryonic brain. When the foregut and mesoderm of Drosophila are ablated, brain patterning is disrupted. The loss of Hedgehog expressed in the foregut appears to mediate this effect, as it does in vertebrates. One mechanism whereby these defects occur is a disruption of normal apoptosis in the brain. These data argue that the last common ancestor of protostomes and deuterostomes had a prototype of the brains present in modern animals, and also suggest that the foregut and mesoderm contributed to the patterning of this ‘proto-brain’. They also argue that the foreguts of protostomes and deuterostomes, which have traditionally been assigned to different germ layers, are actually homologous.

Genus Enterovirus

Enterovirus A71 (EV A71) (genus enterovirus, family pircornaviridae) causes benign vesicular lesions on skin (hand, foot and mouth disease, HFMD) and mucous membranes of the mouth (herpangina), and also severe to life-threatening infections of the brain, the heart, and other internal organs. Disease outbreaks in the Asia-Pacific region regularly involve thousands of children <5 years resulting in many deaths. Such outbreaks are caused by specific EV genotypes that vary by time and place. While there are various promising and innovative options for treatment in development, none are licensed to date. Immunoglobulins may be beneficial through virus neutralization and modulation of the inflammatory response by the host. In China, 3 different highly efficacious and safe vaccines are commercially available; however, none are licensed outside the country. Roughly half a dozen vaccines are in the development pipeline, with some using innovative approaches and trying to broaden strain coverage.

The Brain

Over the past decade, major discoveries in retrotransposon biology have depicted the neural genome as a dynamic structure during life. In particular, the retrotransposon LINE-1 (L1) has been shown to be transcribed and mobilized in the brain. Retrotransposition in the developing brain, as well as during adult neurogenesis, provides a milieu in which neural diversity can arise. Dysregulation of retrotransposon activity may also contribute to neurological disease. Here, we review recent reports of retrotransposon activity in the brain, and discuss the temporal nature of retrotransposition and its regulation in neural cells in response to stimuli. We also put forward hypotheses regarding the significance of retrotransposons for brain development and neurological function, and consider the potential implications of this phenomenon for neuropsychiatric and neurodegenerative conditions.
