X-ray powder diffraction of red kangaroo (Macropus rufus) dental enamel, with a relative density greater than 2.60, showed a longer a-axis length of the apatite unit cell, a = 9.462 A, a shorter c-axis length, c = 6.877 A, and a smaller crystallite size, ca. 185 A, than those of human dental enamel. The a-axis of red kangaroo dental enamel was one of the longest among the values reported previo...

Using long-term data on two kangaroo rats in the Chihuahuan Desert of North America, we fitted logistic models including the exogenous effects of seasonal rainfall patterns. Our aim was to test the effects of intraspecific interactions and seasonal rainfall in explaining and predicting the numerical fluctuations of these two kangaroo rats. We found that logistic models fit both data sets quite ...

Introduction: Infantile colic has been defined as episodes of excessive and persistent crying without known medical cause. Kangaroo mother care is a new method for case of newborn with several advantages. This study designed for evolution KMC and its effect on infantile colic. Methods: This study is a randomized controlled trial, from 1th may 2008 to 1th may 2009 a total of 70 children, aged 3-...

This study aims to identify the benefits of kangaroo care on physiological function premature infants with mechanical ventilation support. The method used is a systematic review through article searches Proquest, ScienceDirect and Ebsco data sources. results showed that intervention in who were mechanically ventilated was not only safe but also stabilized improved function. In conclusion, provi...

BACKGROUND To compare cost effectiveness of 'Kangaroo Ward Care' with 'Intermediate Intensive Care' in stable very low birth weight infants (birth weight < 1100 g). METHODS This is the secondary analysis of the study in which we have analysed the cost effectiveness of 'Kangaroo ward care' (KWC) with 'Intermediate Intensive Care' (IIC). In this randomized control trial 141 infants (less than 1...

We hypothesize that the inner medulla of the kangaroo rat Dipodomys merriami, a desert rodent that concentrates its urine to more than 6,000 mosmol/kgH(2)O water, provides unique examples of architectural features necessary for production of highly concentrated urine. To investigate this architecture, inner medullary nephron segments in the initial 3,000 μm below the outer medulla were assessed...

1045-2249/92/14.00 © 1992 International Society for Behavioral Ecology We observed radio-implanted Merriam's kangaroo rats disposing of 10-g bonanzas of rolled oats in 48 trials in the field. The principal determinant of the initial disposition of discovered food was apparently its distance from the day burrow: food found within about 10m was mainly larder hoarded, whereas food encountered fart...

is it possible to discharge a 2-3 hours, 1134 g weight breast feeding newborn in 24 -36 hours from hospital?   yes, in materno pediatric hospital located in bogatto-clombia it is a routine. it is an approach to prevent high costs and nosocomial infections. it also used to establish a deep relationship based on natural and instinct process.   newborns who are in satisfactory clinical situations,...

To establish whether poisoning programs affect non-target density, the null hypothesis that density does not decline on poisoned sites needs to be tested. However, where no statistically significant reduction in density is found, there is some probability that a biologically significant reduction has been overlooked. The probability that such an error has occurred (a Type 2 error) depends on th...

One common goal in evolutionary biology is the identification of genes underlying adaptive traits of evolutionary interest. Recently next-generation sequencing techniques have greatly facilitated such evolutionary studies in species otherwise depauperate of genomic resources. Kangaroo rats (Dipodomys sp.) serve as exemplars of adaptation in that they inhabit extremely arid environments, yet req...
