The muscle forces and stresses occurring during normal locomotor activity in kangaroo rats are compared with the peak isometric force developed by the same muscles in situ. Two methods were used simultaneously to determine the stresses (force/cross-sectional area) acting in the ankle extensors during steady-speed hopping and during jumps when animals were startled: a direct measurement using a ...

background : due to the higher risk of  pain in preterm infants, pain management is important for such infants. the present study aimed to determine the effectiveness of kangaroo care on the severity of pain and physiological parameters after heel-stick in preterm infants. materials and methods: this was a prospective and randomized controlled cross-over study. twenty preterm infants allocated ...

Occludin has been identified from chick liver as a novel integral membrane protein localizing at tight junctions (Furuse, M., T. Hirase, M. Itoh, A. Nagafuchi, S. Yonemura, Sa. Tsukita, and Sh. Tsukita. 1993. J. Cell Biol. 123:1777-1788). To analyze and modulate the functions of tight junctions, it would be advantageous to know the mammalian homologues of occludin and their genes. Here we descr...

We investigated the impact of red fox (Vulpes vulpes Linnaeus 1758) predation on juvenile eastern grey kangaroos (Macropus giganteus Shaw 1790) using a replicated predator removal experiment. In two sites in Namadgi National Park, south-eastern Australia, a persistent 1080 poisoning campaign over 18 months reduced fox density by more than 85%, and to less than 10% of the fox density in two othe...

Phylogeographic studies around the world have identified refugia where fauna were able to persist during unsuitable climatic periods, particularly during times of glaciation. In Australia the effects of Pleistocene climate oscillations on rainforest taxa have been well studied but less is known about the effects on mesic-habitat fauna, such as the eastern grey kangaroo (Macropus giganteus). The...

Some granivorous rodents scatter hoard; they bury seeds in shallow pits throughout their territory. These buried caches can represent food stores for the hoarders, food for competitors, or a means of seed dispersal and propagation for plants. Large numbers of seeds may be buried in many caches throughout an area; thus, fate of caches has important consequences for granivores, other animals, and...

ß Behavioral audiograms were determined for four species of Glires: one Iagomorph (domestic rabbit, Oryctolagus cuniculus) and three feral rodents (cotton rat, Sigmodon hispidus; house mouse, Mus rnuseulus; and kangaroo rat, Dipodomys rnerrlarni). Considerable variation in hearing ability was found among the four species with low-frequency hearing limits ranging over 5-1/2 octaves from 50 (kang...

In [BKT11] Baba, Kotyada and Teja introduced the FACTOR problem over non-abelian groups as base of an ElGamal-like cryptosystem. They conjectured that there is no better method than the naive one to solve the FACTOR problem in a general group. Shortly afterwards Stanek published an extension of the baby-step giant-step algorithm disproving this conjecture [Sta11]. Since baby-step giant-step met...

The provision of maternal-infant body contact during a period of maternal separation was examined for its effects on parent-infant and triadic interactions. Participants were 146 three-month-old preterm infants and their parents, half of whom received skin-to-skin contact, or kangaroo care (KC), in the neonatal nursery. Global relational style and micro-patterns of proximity and touch were code...

BACKGROUND AND OBJECTIVE: Involvement of fathers, as important members of every family, in the care of premature infants is a major challenge. Therefore, it is essential to understand the feelings of fathers towards infant care. The aim of this study was to determine the effects of kangaroo care on tension in fathers of premature infants hospitalized in a neonatal intensive care unit. METHODS: ...
