The effects of ovariectomy on bone mineral density, geometrical, and biomechanical characteristics in the rabbit femur
Authors: Kara M. E. , Sevil F. 
Published: December 2009

SummaryThe aim of the study was to evaluate the bone mineral density, as well as the biomechanic and morphometric changes in the femur of ovariectomised rabbits.Twenty-four six-month-old New Zealand rabbits were randomly divided into an ovariectomy (n = 12) and a sham (n = 12) group. Six rabbits in each group were euthanatized at eight and 16 weeks after surgery, and the femora were resected. The morphometric data were obtained from tomographic images. Periosteal and endosteal diameters and cortical thickness were measured. Total cross-sectional, cortical and medullary areas were also measured. The bone mineral content, the bone area and the bone mineral density were measured from the proximal, distal and mid-shaft of the femur as well as the total femur by dual energy X-ray absorptiometry. Employing the three-point bending method, the ultimate force, stiffness and work-to-failure were measured. The mechanical data were normalised to obtain intrinsic biomechanical properties such as ultimate stress, elastic modulus, and toughness, all of which are independent of size and shape.The results indicated that the femur was both larger and weaker 16 weeks after surgery in the ovariectomised group. Results also suggest that the rabbit might be a useful animal model for investigation of diseases related to oestrogen loss such as human postmenopausal osteoporosis. However, additional studies with advanced techniques at several time points via in vivo animal studies, and precision and predictability analyses should be designed to standardise the rabbit as a model for osteoporosis.

Summary
Objectives: To report on the frequency and distribution of lesions of the medial coronoid process in dogs of six years of age and older, and to describe the arthroscopic findings in the affected joints. To compare those lesions seen in ‘old’ dogs with those seen in ‘young’ dogs between the ages of five and 18 months.
Methods: A retrospective study of dogs six-years-old and older admitted for elbow lameness and subsequent elbow arthroscopy. The dogs were divided into groups according to the lesions of the medial coronoid process diagnosed during arthroscopic examination and computed tomography (CT). The radio-graphic degree of osteoarthritis (OA) and arthroscopically diagnosed lesions on the medial humeral condyle are described.
Results: In 51 ‘old’ dogs, five types of lesions could be identified on arthroscopy and CT: chondromalacia-like lesions (2%), fissures (27.5%), non-displaced fragments (12%), displaced fragments (27.5%), and erosions within the medial compartment without fragmentation (31%). A significantly different distribution of lesions was seen in ‘young’ dogs: fissures (23%), non-displaced fragments (45%), displaced fragments (29%), and erosions within the medial compartment without fragmentation (3%). No difference in radio-graphic degree of OA was seen between the two groups.
Clinical significance: This study demonstrates the relatively high incidence of medial coronoid disease in dogs older than six years of age, and it highlights one particular problem in ‘old’ dogs: the complete erosion of the medial compartment.
Surgical management of large segmental femoral and radial bone defects in a dog
Authors: Shani J. , Segal U. 
Published: December 2009

SummaryIn this case report, we describe the use of a cylindrical titanium mesh cage combined with cancellous bone graft to surgically manage large segmental bone defects in a dog. A seven-year-old, neutered male cross-breed dog, with highly comminuted fractures of the right femur and the left radius and ulna, was referred for treatment. Previous open reduction and internal fixation of these fractures had failed. Following implant removal and debridement of each bone, a 71 mm segmental femoral defect and a 27 mm segmental radial defect were present. A commercially available cylindrical titanium mesh cage was filled with ß-tricalcium phosphate crystals mixed with an equal volume of autogenous cancellous bone graft. The mesh cage was aligned with the proximal and distal parts of each bone using an intramedullary pin passing through the cage, and a locking plate was applied to the proximal and distal fracture fragments to produce compression against the titanium cage. The dog had a successful long-term clinical outcome, and radiographic examination at 22 and 63 weeks after surgery showed the formation of remodelling bridging callus that was continuous across the titanium cage in each of the fractures. Due to the relative simplicity of the technique and the favourable outcome in this case, it should be considered an option when managing comminuted fractures with large bone defects.

Abstract
As thymocytes differentiate, Ag sensitivity declines, with immature CD4−CD8− double-negative (DN) cells being most susceptible to TCR signaling events. We show that expression of αβTCR from the DN3 stage lowers the threshold for activation, allowing recognition of MHC peptides independently of the TCR β-chain and without either T cell coreceptor. The MHC class I-restricted C6 TCR recognizes the Y-chromosome–derived Ag HYKkSmcy. Positive selection in C6 αβTCR females is skewed to the CD8 compartment, whereas transgenic male mice exhibit early clonal deletion of thymocytes. We investigated the effect of the HYKkSmcy complex on developing thymocytes expressing the C6 TCR α-chain on a TCR-α−/− background. On the original selecting haplotype, the skew to the CD8 lineage is preserved. This is MHC dependent, as the normal bias to the CD4 subset is seen on an H2b background. In male H2k C6 α-only mice, the presence of the HYKkSmcy complex leads to a substantial deletion of thymocytes from the DN subset. This phenotype is replicated in H2k C6 α-only female mice expressing an Smcy transgene. Deletion is not dependent on the β variable segment of the C6 TCR or on a restricted TCR-β repertoire. In contrast, binding of HYKkSmcy and Ag-specific activation of mature CD8+ T cells is strictly dependent on the original C6 β-chain. These data demonstrate that, in comparison with mature T cells, αβTCR+ immature thymocytes can recognize and transduce signals in response to specific MHC-peptide complexes with relaxed binding requirements.

Impact of recycling stillage on conversion of dilute sulfuric acid pretreated corn stover to ethanol
Authors: Mohagheghi Ali , Schell Daniel J. 
Published: December 2009

AbstractBoth the current corn starch to ethanol industry and the emerging lignocellulosic biofuels industry view recycling of spent fermentation broth or stillage as a method to reduce fresh water use. The objective of this study was to understand the impact of recycling stillage on conversion of corn stover to ethanol. Sugars in a dilute‐acid pretreated corn stover hydrolysate were fermented to ethanol by the glucose–xylose fermenting bacteria Zymomonas mobilis 8b. Three serial fermentations were performed at two different initial sugar concentrations using either 10% or 25% of the stillage as makeup water for the next fermentation in the series. Serial fermentations were performed to achieve near steady state concentration of inhibitors and other compounds in the corn stover hydrolysate. Little impact on ethanol yields was seen at sugar concentrations equivalent to pretreated corn stover slurry at 15% (w/w) with 10% recycle of the stillage. However, ethanol yields became progressively poorer as the sugar concentration increased and fraction of the stillage recycled increased. At an equivalent corn stover slurry concentration of 20% with 25% recycled stillage the ethanol yield was only 5%. For this microorganism with dilute‐acid pretreated corn stover, recycling a large fraction of the stillage had a significant negative impact on fermentation performance. Although this finding is of concern for biochemical‐based lignocellulose conversion processes, other microorganism/pretreatment technology combinations will likely perform differently. Biotechnol.
