Substance P (SP) and neurokinin A (NKA), encoded by TAC1/Tac1 gene are members of the tachykinin family, which exert their neuromodulatory roles in vertebrate reproduction. In mammals, SP and NKA have been shown to regulate gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) secretion via kisspeptin neurons. On the other hand, the role of SP/NKA in the regulation of reproduction in non-mammalian vertebrates is not well known. In the present study, we first localized expression of tac1 mRNA in the brain of male and female zebrafish, Danio rerio. Next, using an antibody against zebrafish tachykinin1 (Tac1), we examined the neural association of SP/NKA neural processes with GnRH3 neurons, and with kisspeptin (kiss2) neurons, in the brains of male and female zebrafish. In situ hybridization showed an apparent male-dominant tac1 expression in the ventral telencephalic area, the anterior and posterior parts of the parvocellular preoptic nucleus, and the suprachiasmatic nucleus. On the other hand, there was female-dominant tac1 expression in the ventral periventricular hypothalamus. Confocal images of double-labeled zebrafish Tac1 and GnRH3 showed associations between Tac1-immunoreactive processes and GnRH3 neurons in the ventral telencephalic area. In contrast, there was no apparent proximity of Tac1 processes to kiss2 mRNA-expressing neurons in the hypothalamus. Lastly, to elucidate possible direct action of SP/NKA on GnRH3 or Kiss2 neurons, expression of SP/NKA receptor, tacr1a mRNA was examined in regions containing GnRH3 or Kiss2 neurons by in situ hybridization. Expression of tacr1a mRNA was seen in several brain regions including the olfactory bulb, preoptic area and hypothalamus, where GnRH3 and Kiss2 cells are present. These results suggest that unlike in mammals, Tac1 may be involved in male reproductive functions via direct action on GnRH3 neurons but independent of kisspeptin in the zebrafish.

This study discusses about language use occurred by male and female host in Hitam Putih talk show. The method of this research is descriptive qualitative. The subjects of this study are male and female host in Hitam Putih talk show. The data are the utterances produced by male and female host in Hitam Putih talk show. This research focuses on the show broadcasted on October 2016 by taking 4 videos randomly. The objective of this study is to describe kinds of the language use uttered by male and female host in Hitam Putih talk show. The findings showed that the kinds of language use consist of 6 parts. The dominant language use uttered by male host is expletive, because male’s utterances are frequently stated in a negative connotation. On the other hand, female host utterances are found in specialized vocabulary as the most dominant because female host has more interest in talking family affairs, such as the education of children, clothes, cooking, and fashion, etc. Women also tended to talk about one thing related to the home and domestic activities. However, the representation of language use uttered by male and female are deficit, dominance and different. Keywords: Language Use, Gender, Talk Show

When one hears the term “ground cover,” one immediately thinks of “grasses.” This perception is so deep-seated that paleobotanists even have been overheard to proclaim that “there was no ground cover before grasses.” Today grasses are so predominant in many environments that this perception is perpetuated easily. On the other hand, it is difficult to imagine the absence or lack of ground cover prior to the mid-Tertiary. We tested the hypothesis that different forms of ground cover existed in the past against examples from the Recent and the fossil record (Table 1). The Recent data were obtained from a large number of sources including those in the ecological, horticultural, and microbiological literature. Other data were derived from our knowledge of Precambrian life, sedimentology and paleosols, and the plant fossil record, especially in situ floras and fossil “monocultures.” Some of the data are original observations, but many others are from the literature. A detailed account of these results will be presented elsewhere (Pfefferkorn and LePage, in preparation).

Background: Fluoride protects the teeth from dental caries using the needed amount of fluoride products.Methods: A Modified structured questionnaire has been validated through a pilot trial (20 responses) prior to administration that contains16 questions was distributed. Other than the demographics, the data were collected from 500 participants including undergraduate male and female dental students.Results: The majority described the mild fluorosis appearance in the teeth according to Dean’s index appropriately as white opacity of the enamel (64%, n=320). On the other hand, only 31.1% (n=155) and 46% (n=229) described the moderate and severe fluorosis appearance in the teeth according to Dean’s index appropriately.Conclusions: The dissemination and education about dental fluorosis is urgently needed and should be tailored to reach this population. The knowledge about causes of fluoride and the effect on dental fluorosis should be presented in the education.

Abstract As there have been many researches for bolt self-loosening and a lot of knowledge have been accumulated, the phenomena has been understood more and more clearly. On the other hand, it is quite difficult to achieve both non-self-loosening and easy bolting tasks. In practical situations, easy and stable bolting is more focused and torque control is employed for tension control in the fields. For the stable bolting, friction of the threads is reduced by lubrication. However, the effect of this friction reduction is not yet investigated in the aspect of self-loosening. In this paper, the effect of frictions between male and female threads and between nut and bearing surface is investigated by FEA simulations. This provides information how self-loosening can be controlled. In this paper, the motion of the fastened plate transverse to the bolt axis is considered. This motion is known as the easiest motion to make self-loosening in experience and also as shown so in the author’s previous researches. The friction seems to increase self-loosening and also decrease self-loosening at the same time. It seems that the friction on the bearing surface drives self-loosening and friction on the thread surfaces prevents it. In this paper, both the frictions are examined in the relative manner with the Finite Element Analyses.

Stems of Ecquisetites columnaris (Brong.) have long been known to occur in a vertical position in the sandstones of the Inferior Oolite on the Yorkshire coast. This mode of occurrence has commonly been held as proving that the stems are preserved in the position in which they once grew, having been buried in situ beneath the layers of sand that accumulated on the spot. On the other hand, it has been argued that the upright position need not be primary; it might be as readily explained if the stems are regarded as drifted and secondarily deposited on the spots where they are now found. It is well known and has been pointed out, particularly in the discussions of the upright stems in the Coal-measures, that a drifting tree often has a tendency to sink in a vertical position, the root-end being heavier because of adhering mineral matter or from some other reason. Phillips describes, in his Geology of the Yorkshire Coast, a locality at High Whitby where upright stems of Equisetites columnaris occur in the sandstone. He continues: “They … are broken off or imperfect above, and seldom reach to the upper surface of the bed; they are also broken off below, but commonly pass to the lower surface; and some of the lower joints nearest the roots are found in the subjacent bed of shale.”

This study compares degree of homophobia between social work and non-social work students. The results show that although social work students are not significantly different from non-social work students in their levels of homophobia, both male and female social work students are significantly less homophobic than male non-social work students. On the other hand, somewhat surprisingly, female social work students are significantly more homophobic than female non-social work students on the issues of whether homosexuality is a sin and whether homosexuality is disgusting. Implications for social work education are discussed.

SummaryThis study compares the incidence of a variety of cutaneous conditions among 91 patients treated with lithium carbonate with the incidence of such conditions among 44 patients treated with other non-neuroleptic, maintenance medications. Data on cutaneous conditions and allergies were obtained using structured interviews, demographic data, medication histories and personal and family histories.A significantly greater proportion of the lithium-treated patients than the comparison patients reported a cutaneous condition which may have been secondary to treatment in that it developed for the first time after the medication or appeared to have been exacerbated by the medication. Among the lithium-treated patients, females were found to be significantly more likely to report a secondary cutaneous condition. This effect was found across the whole range of cutaneous conditions. Male lithium-treated patients on the other hand reported approximately the same rate of secondary cutaneous conditions as both male and female comparison patients. Possible reasons for this sexual effect on incidence are discussed.The literature on cutaneous conditions which have been associated with lithium therapy is also reviewed.

ABSTRACT There is a big difference between male and female in the rural environment of Bangladesh and the aim of this eating habits and nutritional status. The study was conducted through 384 respondents from 9 villages in Ishwardi, Pabna; a north-western district of Bangladesh. The research has done on the food habits of the middle and lower class people of the villages. And some informations are collected from the different sources. In the research 73.44% of male earn more than 24 thousand BDT per month when only 43.32% female are earning more than 24 thousand BDT. Most of the female are housewives and male are service holder. 44.79% male  are service holder on the other hand 4.69% female are service holder. Rice is the main food for Bangladesh. So, most of the people have rice on daily three times. 37.80% of female and 66.98% of male are having rice. Ruti is the second priority food, female take this food 0.56% and male take 7.55% for 2 days. 63.33% female take egg, on the other hand 58.07% male take egg per week.  3.2% female her meal last of all and 1.5% female take it first of all. On the other hand 6.25% male take their meal first of all and 3.39% male take their meal last of all. Most of the female are normal having BMI 89.06% on the other hand male are overweight 78.18%. In the light of the study the eating habits of male and female in Bangladesh have improved but it has not yet affected everyone.

Some people still cannot talk freely about sex education. On the other hand, some of them have an assumption about teaching sex education will leads to free sex behavior. Sometimes parent afraid to talk about sex education with their children, even some parent think sex education is not important thing for children.However, in fact children need to know about sex education for their own good. To children, sex education is to explain differences in male and female and to know well about themselves. Create media to deliver sex education is the way to teach children about sex education. Among many media, game is one option to deliver this education.This research will discuss about game for childs sex media education. Use game as sex media education because game has capability to deliver message. Through game concept, picture, and animation, game deliver childs sex education to children. With the objective to prevent child from sexual abuse. However, when children play the game they need companion to make clear that children understand the meaning of game message through game story.

X Irradiation

An in situ perfusion method was used to measure glucose absorption from the x-irradiated or nitrogen-mustard-treated rat. Inhibition was greatest 3 days after treatment and recovery had begun by the 6th day. The effect on absorption was not appreciably different after 900 r than after 1,500 r, although histologic damage was much greater after the higher dose. Pretreatment with cysteine or AET prevented the decreased absorption after 900 r but did not protect against 1,500 r nor against the effect of HN2. The absorption of d(+)-xylose was also decreased 3 days after irradiation of the intestine. Thus, both active and passive transport mechanisms involved in sugar absorption were decreased by irradiation of the intestine. The absorption of fat, on the other hand, was not decreased as a result of direct action by x-radiation on the intestinal epithelium, since oleic acid absorption was unaffected by exposure of the intestine to radiation.
