And Function

The gastric armature of decapod foregut is a feeding structure that sparks controversial debates about the role dietary and historical components have in shaping its morphological traits. Having previous information about the natural diet is an interesting way to gather evidence on this issue. For the present study, we analyzed the morphological traits of gastric ossicles involved directly in the maceration of food in nine species of freshwater crabs of the family Trichodactylidae (Brachyura: Decapoda) representing five genera, three tribes and two subfamilies. The analyzed gastric ossicles were quite consistent among closely related species, suggesting that the observed traits had a clear phylogenetic component. However, it was also noted that the morphological traits of the gastric teeth of trichodactylid crabs match well with the natural diet and presented likeness with general features of other species with a similar trophic habit. We discuss the influence of phylogeny and function on the design of morphological traits and propose to quantify the role of phylogeny and function in shaping morphological traits through the analysis of phylogenetic signals.

The radula morphology and variability in four European species of the family Viviparidae viz. Viviparus viviparus (Linnaeus, 1758), V. sphaeridius (Bourguignat, 1880), V. ater (Cristofori et Jan, 1832) and Contectiana listeri (Forbes et Hanley, 1853) were examined using scanning electron microscopy (SEM). Statistical methods reveal a certain value of rachidian tooth dimensional parameters as an efficient tool for taxonomy and discrimination of closely related species of the family.

And Function

Excessive infiltration of immune cells into the kidney is a key feature of acute and chronic kidney diseases. The family of chemokines are key drivers of this process. CX3CL1 (fractalkine) is one of two unique chemokines synthesized as a transmembrane protein which undergoes proteolytic cleavage to generate a soluble species. Through interacting with its cognate receptor, CX3CR1, CX3CL1 was originally shown to act as a conventional chemoattractant in the soluble form, and as an adhesion molecule in the transmembrane form. Since then, other functions of CX3CL1 beyond leukocyte recruitment have been described, including cell survival, immunosurveillance, and cell-mediated cytotoxicity. This review summarizes diverse roles of CX3CL1 in kidney disease and potential uses as a therapeutic target and novel biomarker. As the CX3CL1-CX3CR1 axis has been shown to contribute to both detrimental and protective effects in various kidney diseases, a thorough understanding of how the expression and function of CX3CL1 are regulated is needed to unlock its therapeutic potential.

Genomes contain a large number of genes that do not have recognizable homologues in other species. These genes, found in only one or a few closely related species, are known as orphan genes. Their limited distribution implies that many of them are probably involved in lineage-specific adaptive processes. One important question that has remained elusive to date is how orphan genes originate. It has been proposed that they might have arisen by gene duplication followed by a period of very rapid sequence divergence, which would have erased any traces of similarity to other evolutionarily related genes. However, this explanation does not seem plausible for genes lacking homologues in very closely related species. In the present article, we review recent efforts to identify the mechanisms of formation of primate orphan genes. These studies reveal an unexpected important role of transposable elements in the formation of novel protein-coding genes in the genomes of primates.

Abstract The genus Galea Meyen, 1833 includes at least five species of terrestrial, diurnal and herbivorous cavies that occupy grasslands and rocky scrub areas at both high and low elevations in South America. According to the available molecular and morphological data, Galea comes Thomas, 1919 is restricted to highland areas above 2000 m in southern Bolivia and northwestern Argentina. Its distributional range as well as its morphological distinctiveness from other closely related species (Galea leucoblephara and Galea musteloides) is poorly documented. Using both qualitative and quantitative morphological traits, we provided an emended diagnosis for G. comes. In addition, we added six new locality records to its known distribution.

Members of the family Proteaceae have extremely low mature fruit : flower (FR : FL) ratios (range 0.001–0.163) compared with other temperate, hermaphroditic, woody perennials. Sutherland’s (1986) survey of FR : FL ratios indicated that compatibility was an important factor explaining levels of fruit set. The role of compatibility in regulating FR : FL ratios was tested in five closely related species of Grevillea (Proteaceae). Species-specific compatibility was compared using the self-compatibility index (SI = ratio of selfed fruit set to crossed fruit set) calculated at fruit initiation to minimise the confounding effect of other post-fertilisation fruit losses, such as inbreeding depression and pre-dispersal predation. Fruit : flower ratios at initiation ranged from 0.041–0.249, and at maturity 0.015–0.096. Grevillea species showed highly variable breeding systems: G. linearifolia was self-incompatible (SI = 0.003), G. sphacelata, G. mucronulata, and G. oleoides were partially self-compatible (SI = 0.07–0.28) and G. longifolia was self-compatible (SI = 0.61). Intrapopulation variability in the level of self-incompatibility was high in all species but G. linearifolia. The correlation between SI and FR: FL ratios was non-significant, indicating that compatibility has a minimal effect on fruit set in the Grevillea species studied, and that these data, together with other data on proteaceous species do not support trends observed in Sutherland’s survey. Low FR : FL ratios resulted from of a combination of pollen limitation, and high levels of flower and fruit predation.

Madrasah in the Middle East has known eight or nine centuries before madrasah in Indonesia, which emerged as a reaction to the reform movement as well as a response to the policy of Dutch colonizers secular education. Madrasah got a decent place in Indonesia after rising SKB 3 minister (Minister of Interior, Minister of Education and Culture, and the Minister of Religious Affairs) in 1975, where madrasas equated with other schools in terms of the status of the diploma, graduates continuing education opportunities and changing schools. In a further development, the school as disoriented. It is caused by two things: first, a paradigm shift towards sekularistik. Education implementation has marred even be interpreted as a partial instead of a holistic paradigm as desired by Islam. Supposedly, the madrasa education as a whole should make Islam as a principle in the determination of educational objectives, the formulation of the curriculum and standard of value of science and the learning process, including determining the qualifications of teachers and school culture that will be developed in the madrasas. Second, the functional institutional weakness as a result of shifting the orientation and function of the family and their influence and societal demands materialistic-hedonistic.The weakness seen in a mess madrasa curriculum, not optimal role of teachers as well as school culture that is not in line with the will of Islam.

Role And Function

<p>Family is one of the social institutions in the community. Family is also a place for children to acquire mental coaching and personality formation. The family has a considerable role and function on the development and future of the child. However, in fact the violence of children in the family often occurs, such as violence involving fathers, mothers and other siblings. Lack of knowledge and insight related to parenting, growth and development of children is one factor in the occurrence of violence against children. From various cases of child violence, one of NGO named Yayasan SAMIN that cares about child issues to make efforts to prevent and treat child violence in the family. This research aims to know 1) how the role of Yayasan SAMIN in the prevention and handling of child violence in the family, 2) How to form the prevention and handling conducted by the Yayasan SAMIN against Child abuse cases in Family. The results of this study show that 1) Yayasan SAMIN has been explaining its role in the prevention of child violence against parents and the treatment of child abuse victims in families, 2) The prevention of child violence by parents is socialization, campaigning, and KIE (communication, information, education). The form of treatment of victims of violence is with mentoring.</p>
