Enhancing feed efficiency (FE) in cattle continues to be an important goal in the beef industry. Previous research suggests improving FE may alter calpain system activity, potentially having negative effects on meat tenderness. The objective of this study was to assess the potential influence of beef cattle FE on postmortem meat tenderness. During the growing phase, 181 crossbred steers were fed for 76 d at the University of Missouri on a whole shell corn-based diet (MU-Corn; = 90) or a roughage-based diet (MU-Rough; = 91)...

Skeletal fluorosis (SF) is an osteosclerotic metabolic bone disorder caused by excessive ingestion or inhalation of fluoride. SF is extremely rare in developed countries. We report a case of SF due to inhalational abuse from a fluoride-containing air dust cleaner. A 33-year-old man with no past medical history presented with progressively worsening low back pain for 2 years. Physical examination was notable for loss of lumbar lordosis and tenderness over the lumbar spine. Radiographs were notable for uniform generalized osteosclerosis in the long bones, entire spine, rib cage, and pelvic bones, and loss of the normal lumbar curvature...

Background  Tears of the dorsal radiocarpal capsule at the level of the scapholunate interosseous ligament (SLIL) have recently been described in association with predynamic scapholunate instability. Purpose  The aim of this anatomical study of the dorsal capsulo-scapholunate septum (DCSS) was to examine the connection of the dorsal capsule on the SLIL and dorsal intercarpal ligament (DICL). Methods  Fourteen fresh frozen wrists from seven adult cadavers were dissected through a dorsal approach. Any dorsal attachment of the DICL on the dorsal surface of the SLIL, that is, the DCSS, was identified and measured (height and width)...

Hypophosphatasia is a very rare bone metabolism disorder caused by a deficiency in alkaline phosphatase activity, due to mutations in the ALPL gene. Its clinical hallmark is the impairment of skeletal and teeth mineralisation, although extra-skeletal manifestations are frequent. Its phenotypic spectrum is widely variable from a subtype with exclusive odontological impairment (odontohypophosphatasia) to five subtypes with systemic involvement, classified according to the age at the onset of the first symptoms (four of them in the paediatric age range: perinatal lethal, perinatal benign, infant and childhood hypophosphatasia)...

Proton pump inhibitors (PPIs) are widely used to treat gastric acid-related disorders. Concerns have been raised about potential fracture risk, especially at the hip, spine and wrist. However, fracture risk at other bone sites has not been as well studied. We investigated the association between PPIs and specific fracture sites using an aggregated knowledge-enhanced database, the Food and Drug Administration Adverse Event Reporting System Data Mining Set (AERS-DM). Proportional reporting ratio (PRR) was used to detect statistically significant associations (signals) between PPIs and fractures...

In children presenting with a pectus excavatum (PE) or pectus carinatum (PC) an underlying syndrome including Marfan's syndrome needs to be excluded. In adolescents, severe chest wall deformities may cause cardiac or respiratory problems but most commonly they have a psychological impact. The conservative treatment is a Vacuum Bell for PE, and a Dynamic Compression System for PC ; they play an increasing role in young patients. These devices need to be worn multiple hours per day for several months for an optimal result...

Supernumerary lumbar ribs are usually asymptomatic and discovered incidentally during routine diagnostic radiography. During a routine inventory of the research skeletal repository at the University of the Witwatersrand, a rare case of bilateral supernumerary ribs on the first lumbar vertebra was observed. The skeletal specimen belonged to a 70-year-old African male whose recorded cause of death was esophageal carcinoma. Plain radiography revealed bilateral joint cavities between the transverse processes of the first lumbar vertebra and the supernumerary ribs...

PURPOSE: We have demonstrated the ability to identify coronary calcium, a reliable biomarker of coronary artery disease, using non-gated, 2-shot, dual energy (DE) chest x-ray imaging. Here we will use digital simulations, backed up by measurements, to characterize DE calcium signals and the role of potential confounds such as beam hardening, x-ray scatter, cardiac motion, and pulmonary artery pulsation. For the DE calcium signal, we will consider quantification, as compared to CT calcium score, and visualization...

NEK family kinases are serine/threonine kinases that have been functionally implicated in the regulation of the disjunction of the centrosome, the assembly of the mitotic spindle, the function of the primary cilium and the DNA damage response. NEK1 shows pleiotropic functions and has been found to be mutated in cancer cells, ciliopathies such as the polycystic kidney disease, as well as in the genetic diseases short-rib thoracic dysplasia, Mohr-syndrome and amyotrophic lateral sclerosis. NEK1 is essential for the ionizing radiation DNA damage response and priming of the ATR kinase and of Rad54 through phosphorylation...

Rhinoplasty is one of the most delicate procedures in plastic and reconstructive surgery. Precision in every millimeter is vital in ensuring a better quality of surgical outcome. Many methods have been developed to fulfill this requirement. One such method is an implant, whether autogenous or artificial. Artificial implants involve several surgical complications, such as recipient rejection of implant material, infections, and rigid feel of the nasal tip. Hence, autogenous implants were eventually more widely applied, with material being obtained from the septum, concha, or rib cartilages...

INTRODUCTION: Surgical Stabilization of Rib Fractures (SSRF) has become pivotal in the management of severe chest injuries. Recent literature supports improved outcomes and mortality in severe fracture and flail chest patients who undergo SSRF compared to non-operative management (NOM). A 2014 National Trauma Data Bank (NTDB) review provided a point prevalence of 0.7% SSRF in flail patients. We hypothesize that this prevalence is increasing and that temporal, regional, and American College of Surgeons (ACS) trauma designation vary in SSRF utilization...

PURPOSE: Rib fractures are a common chest injury that can typically be treated nonoperatively. However, a percentage of these will go on to nonunion, either because of unique characteristics of the fracture itself or because of a variety of poor healing factors of the host. If a patient has continued symptomology beyond 3 months, surgeons may consider operative management. METHODS: Although isolated resection of fibrous scar tissue from the nonunion site may be sufficient in some cases, it may also be necessary to provide additional structural integrity to the rib depending on the extent of the fracture pattern and resection...

BACKGROUND: We have previously shown that treatment with valproic acid (VPA) decreases brain lesion size in swine models of traumatic brain injury (TBI) and controlled hemorrhage. To translate this treatment into clinical practice, validation of drug efficacy and evaluation of pharmacologic properties in clinically realistic models of injury are necessary. In this study, we evaluate neurologic outcomes and perform pharmacokinetic analysis of a single dose of VPA in swine subjected to TBI, hemorrhagic shock, and visceral hemorrhage...

Objectives The aims of this study were to describe the paravertebral brachial plexus (PBP) blockade in cats, and compare the spread of bupivacaine-methylene blue solution (BMS) using two volumes of injection into the PBP. Methods Six cadavers (4.4 ± 1.8 kg) randomly received 0.15 ml/kg (LOW) or 0.2 ml/kg (HIGH) per injection of BMS into the PBP. The first injection was made ventral to the transverse process of the sixth cervical vertebra (nerves C6 and C7) at the emergence of nerve roots. A second injection was performed at the edge of the cranial border of the scapula and directed ventrally towards the first rib (C8 and T1)...
