A clear picture of skeletal muscle adaptations to obesity and related comorbidities remains elusive. This study describes fiber-type characteristics (size, proportions, and oxidative enzyme activity) in two typical hind limb muscles with opposite structure and function in an animal model of genetic obesity. Lesser fiber diameter, fiber type composition, and histochemical succinic dehydrogenase activity (an oxidative marker) of muscle fiber types were assessed in slow- (soleus) and fast-twitch (tibialis cranialis) muscles of obese Zucker rats, and compared with age- (16 weeks) and sex-matched (females) lean Zucker rats (N=16/group)...

PURPOSE: Screening investigations for the vertebral, anorectal, cardiac, tracheo-oesophageal, renal and limb (VACTERL) association form an important part of the management of neonates with anorectal malformations (ARMs). We developed a proforma to define investigations and indications for referral. The aim of the current study was to determine if the proforma could improve screening rigour. METHODS: Four centres performed a 3-year retrospective audit of neonates with ARM...

The Toll-like Receptor (TLR) adaptor proteins Myeloid Differentiating Factor 88 (MyD88) and Toll, interleukin-1 Receptor and Resistance protein (TIR) domain-containing adaptor inducing interferon-β (TRIF) comprise the two principal limbs of the TLR signaling network. We studied the role of these adaptors in the TLR4-dependent inhibition of allergic airway disease and induction of CD4+ICOS+ T cells by nasal application of Protollin(™) , a mucosal adjuvant composed of TLR2 and 4 agonists. Wild-type (wt), Trif -/- or Myd88 -/- mice were sensitized to birch pollen extract (BPEx), then received intranasal Protollin followed by consecutive BPEx challenges...

Pallister-Killian syndrome (PKS-#OMIM601803) is a multisystem developmental disorder typically due to the presence of an aneuploidy cell line, consisting of a supernumerary tetrasomic chromosomal marker (SCM) arisen from the short arm of chromosome 12 (12p isochromosome). The clinical phenotype, which is strictly related to the percentage and tissue distribution of aneuploid cells, is characterized by craniofacial dysmorphisms, pigmentary skin anomalies, limb shortening, congenital heart defects, diaphragmatic hernia, hypotonia, intellectual disability, and epilepsy...

BACKGROUND: Avoiding major (above-ankle) amputation in patients with diabetic foot ulcers is best accomplished by multidisciplinary care teams with access to infectious disease specialists. However, access to infectious disease physicians is partially influenced by geography. We assessed the effect of living in a hospital referral region with a high geographic density of infectious disease physicians on major amputation for patients with diabetic foot ulcers. We studied geographic density, rather than infectious disease consultation, to capture both the direct and indirect (eg, informal consultation) effects of access to these providers on major amputation...

INTRODUCTION: The natural history of claudication is well characterized and traditional therapy includes risk factor modification and exercise protocols with revascularization reserved for patients who are severely impaired. However, the reduced peri-procedural morbidity with endovascular therapy has led physicians to broaden the indications for intervention for peripheral artery disease and more claudicants are undergoing procedures for disease that is moderately limiting to their lifestyle...

Body mass is an ecologically and biomechanically important variable in the study of hominin biology. Regression equations derived from recent human samples allow for the reasonable prediction of body mass of later, more human-like, and generally larger hominins from hip joint dimensions, but potential differences in hip biomechanics across hominin taxa render their use questionable with some earlier taxa (i.e., Australopithecus spp.). Morphometric prediction equations using stature and bi-iliac breadth avoid this problem, but their applicability to early hominins, some of which differ in both size and proportions from modern adult humans, has not been demonstrated...

This study compared the results of three risk assessment tools (self-reported questionnaire, observational tool, direct measurement method) for the upper limbs and back in a truck assembly plant at two cycle times (11 and 8 min). The weighted Kappa factor showed fair agreement between the observational and direct measurement method for the arm (0.39) and back (0.47). The weighted Kappa factor for these methods was poor for the neck (0) and wrist (0) but the observed proportional agreement (Po) was 0.78 for the neck and 0...

Form is a rich concept that agglutinates information about the proportions and topological arrangement of body parts. Modularity is readily measurable in both features, the variation of proportions (variational modules) and the organization of topology (organizational modules). The study of variational modularity and of organizational modularity faces similar challenges regarding the identification of meaningful modules and the validation of generative processes; however, most studies in morphology focus solely on variational modularity, while organizational modularity is much less understood...

OBJECTIVE: It is well known that sleep-related motor seizures can originate from the temporal lobe. However, little is known about the clinical features of minor motor manifestations during sleep in patients with temporal lobe epilepsy. The main objective of our study was to verify the existence of minor motor events during sleep in patients with mesial temporal lobe epilepsy (MTLE) and to define their clinical features and electroencephalography (EEG) correlations. METHODS: We enrolled in the study patients with diagnosis of symptomatic MTLE and a group of healthy controls...

PURPOSE: The deep component of the distal radioulnar ligament provides translational stability and rotational guidance to the forearm. However, controversy exists regarding the importance of this structure as well as the nature of its attachment to the distal ulna. We aimed to evaluate the topographic anatomy of the distal ulna attachment of both the superficial and the deep components of the radioulnar ligament and to assess the relationship between its internal and its external morphometry...

Recent studies evaluating horses in training and considered free from lameness by their owners have identified a large proportion of horses with motion asymmetries. However the prevalence, type and magnitude of asymmetries when trotting in a straight line or on the lunge have not been investigated. The aim of this study was to objectively investigate the presence of motion asymmetries in riding horses in training by identifying the side and quantifying the degree and type (impact, pushoff) of forelimb and hind limb asymmetries found during straight line trot and on the lunge...

Cornelia de Lange syndrome (CdLS) is a multisystem genetic disorder associated with unusual facial features, limb abnormalities, a wide range of health conditions, and intellectual disability. Mutations in five genes that encode (SMC1A, SMC3, RAD21) or regulate (NIPBL, HDAC8) the cohesin complex have been identified in up to 70% of individuals. Genetic cause remains unknown for a proportion of individuals. There is substantial heterogeneity in all aspects of CdLS but very little is known about what predicts phenotypic heterogeneity...
