A comparative analysis of chick culturing methods on skeletogenesis
This study presents a detailed description of these effects by comparing two different culturing methods: windowed (in the shell) eggs and ex‐ovo or shell‐less culturing to normal development. Using whole mount bone staining, we determined that there is no significant difference in the length of the ossified region of intramembranous and endochondral bones in control versus window cultured embryos. However, these bones are significantly under‐ossified in shell‐less embryos. Shell‐less embryos also exhibit abnormalities in endochondral bones. Intramembranous bones, interestingly, are morphologically normal in shel...

AR‐14‐0079R3 accept for first look The distinct distributions of immunocompetent cells in rat dentin pulp after pulpotomy
ABSTRACT Pulpotomy involves the removal of the coronal portion of pulp, including the diseased tissue, with the intent of maintaining the vitality of the remaining pulpal tissue via a therapeutic dressing. Once odontoblasts suffer injuries, the differentiation of mesenchymal cells is induced from the precursor cell population in the dental pulp, and these cells are recruited to the injured site to differentiate into odontoblasts. However, the involvement of immunocompetent cells during pulpal regeneration remains unclear. Thus, the purpose of this study was to investigate the properties of macrophages that infiltrated woun...

Functional implications of variation in tooth spacing and crown size in Pinnipedimorpha (Mammalia: Carnivora)
This study established the relationship between tooth size and feeding behavior, and provides a new tool to explore the paleoecology of fossil pinnipeds and other aquatic tetrapods. Anat Rec, 2014. © 2014 Wiley Periodicals, Inc. (Source: The Anatomical Record Part B: The New Anatomist)

Effect of point sampling density in quantifying mouse lung emphysema
In this study, we examined this question by focusing on some of the relevant sampling levels in mice with extensive elastase‐induced emphysema. Using fixed samples of tissue blocks, we varied the number of sampling points or intercepts from about 25 to 1000 in control and emphysematous lungs. Our results show that, at the sampling levels investigated, even with the increased heterogeneity in the lung tissue damage caused by elastase, the number of sampling points needed to detect changes is similar to what is needed for control mice.

Observations on Fur development in Echidna (Monotremata, Mammalia) indicate that spines precede hairs in ontogeny
ABSTRACT In the primitive mammal echidna the initial 2‐3 generations of skin appendages produced from birth forms spines and only later true hairs appear. Microscopy on preserved museum specimens reveal that the morphogenesis of spines and hairs is similar but that a larger dermal papilla is formed in spines. The growing shaft comprises a medulla surrounded by a cortex and by an external cuticle. A thick inner root sheath made of cornified cells surrounds the growing shaft inside the spine canal that eventually exits with a pointed tip. Hairs develop later with the same modality of spines but have a smaller papilla and g...

Effect of Calendula officinalis cream on Achilles tendon healing
In conclusion, the topical application of C. officinalis after tendon transection increases the concentrations of collagen and non‐collagenous proteins, as well as the collagen organization in the initial phase of healing.

Coronary Anomalies in Mice with Congenital Heart Defects
Conclusions: The data suggest that vascular smooth muscle recruitment and differentiation are not necessarily linked to other coronary anomalies, such as absence of a main coronary artery or branching patterns.

Brain‐Derived Neurotrofic Factor and its Receptor TrkB are Present, but Segregated, within Mature Cutaneous Pacinian Corpuscles of Macaca Fascicularis
ABSTRACT Some mechanoreceptors in mammals depend totally or in part on the neurotrophins brain‐derived neurotrophic factor (BDNF) and neurotrophin‐4 (NT‐4), and their receptor TrkB, for development and maintenance. These actions are presumably exerced regulating the survival of discrete sensory neurons in the dorsal root ganglia which form mechanoreceptors at the periphery. In addition, the cells forming the mechanoreceptors also express both neurotrophins and their receptors although large differences have been described among species. Pacinian corpuscles are rapidly adapting low‐threshold mechanoreceptors whose d...

Head and cervical spine posture in behaving rats: Implications for modelling human conditions involving the head and cervical spine
This study indicates that, like humans, rats have near vertical orientated cervical vertebral columns but, in contrast to humans, they displace their head in space by movements at both the cervico‐thoracic junction and the cranio‐cervical regions.

Age‐Related Difference in Postural Control During Recovery from Posterior and Anterior Perturbations
Abstract Decreased reactive postural responses in elderly adults may place them at increased risk for falls and related injuries. The first step in addressing the high rate of falls in the elderly population is to determine a baseline for postural response in healthy young and healthy elderly individuals. To determine these age‐related differences in reactive postural responses during recovery from posterior and anterior perturbations, we used the tether‐release method in conjunction with a motion analysis system to evaluate overall movement latencies, overall movement amplitude and velocity, and joint‐specific ampli...

The Nasal Complex of Neanderthals: An entry portal to their place in human ancestry
This study performs quantitative and qualitative analysis of aspects of the nasal complex (NC) in Neanderthals and other later Pleistocene fossils from Europe and Africa. A geographically diverse sample of modern human crania was used to establish an anatomical baseline for populations inhabiting cold and tropical climates. Nasofrontal angle, piriform aperture dimensions, and relative maxillary sinus volume were analyzed along with qualitative features of the piriform aperture rim. Results indicate that Neanderthals and other later Pleistocene Homo possessed NC’s that align them with tropical modern humans. Thus comparis...

Glycine improves biochemical and biomechanical properties following inflammation of the Achilles tendon
ABSTRACT Tendinopathy of the Achilles tendon is a clinical problem that motivates the scientific community to search for treatments that assist in restoring its functional properties. Glycine has broad biological effects, acting as a modulator of the inflammatory cascade, and is the predominant amino acid in collagen. A 5% glycine diet provided beneficial effects against toxicity and inflammation since glycine may restructure the collagen molecules faster due to its broad anti‐inflammatory effects. The purpose was analyze the effects of a 5% glycine diet in rats as a treatment for the inflammatory process. The experiment...
