Relationships of Muscle Function and Subjective Knee Function in Patients After ACL Reconstruction

Background: After anterior cruciate ligament reconstruction (ACLR), relationships between objective measures of muscle function and patient-reported outcomes may change over time. Examining these measures at different time frames after surgery may help develop individualized approaches to improve post-ALCR analysis. Purpose: To examine the associations between subjective knee function and lower-extremity muscle function in individual patients at various time points after ACLR. Study Design: Descriptive laboratory study. Methods: Fifty-one participants who underwent primary, unilateral ACLR (15 males, 36 females; mean age, 22.9 ± 4.5 years; mean height, 172.4 ± 10.1 cm; mean weight, 68.7 ± 13.1 kg) were separated into 3 groups depending on time since surgery (early, <2 years; middle, 2-5 years; late, >5 years). Subjective knee function was quantified using the International Knee Documentation Committee (IKDC) subjective knee form and the Knee injury and Osteoarthritis Outcome Score (KOOS). Isometric knee extension and flexion strength were collected at 90 deg/s. Single-leg hop performance was measured using the single hop, triple hop, cross-over hop, and 6-m timed hop. Coefficient correlations were calculated between subjective knee function and objective measures of muscle function for each group. Results: The early group demonstrated moderate correlations between the KOOS and unilateral measures of flexion peak torque (r = 0.514, P = .035) and flexion power (r = 0.54, P = .027). The middle group demonstrated the strongest correlations between the KOOS and symmetry measures of the single hop (r = 0.69, P = .002) and extension work (r = 0.71, P = .002) as well as unilateral measures of the triple hop (r = 0.52, P = .034) and extension work (r = 0.66, P = .004). The late group demonstrated strong correlations between the 6-m timed hop symmetry and the IKDC (r = 0.716, P = .001) and KOOS (r = 0.71, P = .001). Conclusion: Patients with a post-ACLR status of less than 2 years exhibited stronger relationships with unilateral strength measures to subjective function; graft type was found to change these relationships. Patients at 2 to 5 years postsurgery demonstrated relationships with both unilateral and symmetry measures of muscle function to subjective function. Patients who were more than 5 years after ACLR exhibited strong associations between hopping symmetry and subjective function. Clinical Relevance: Future clinical guidelines for patients after ACLR may need to consider time since surgery as a potential factor.
Output regulation for a class of uncertain systems via fuzzy adaptive control

For a class of nonlinear uncertain systems driven by a linear, neutrally stable exosystem, output regulation problem is considered with the existence of unknown nonlinear function and external disturbances. Using fuzzy logic systems (FLS) to approximate the unknown functions, a fuzzy adaptive observer is designed to estimate the state. An internal model equation with error is designed via exosystem information, fuzzy adaptive output feedback control is constructed recursively that combined the backstepping technique with adaptive FLS. It is shown that the proposed fuzzy adaptive control approach ensures all signals to be bounded and the error signal to be within a desired range. Simulation results via exosystem information illustrate the effectiveness of the control scheme.
Genomic and Biochemical Insights into the Specificity of ETS Transcription Factors

β-barrel membrane proteins perform important functions in the outer membranes (OMs) of Gram-negative bacteria and of the mitochondria and chloroplasts of eukaryotes. The protein complexes that assemble these proteins in their respective membranes have been identified and shown to contain a component that has been conserved from bacteria to humans. β-barrel proteins are handled differently from α-helical membrane proteins in the cell in order to efficiently transport them to their final locations in unfolded but folding-competent states. The mechanism by which the assembly complex then binds, folds, and inserts β-barrels into the membrane is not well understood, but recent structural, biochemical, and genetic studies have begun to elucidate elements of how the complex provides a facilitated pathway for β-barrel assembly. Ultimately, studies of the mechanism of β-barrel assembly and comparison to the better-understood process of α-helical membrane protein assembly will reveal whether there are general principles that guide the folding and insertion of all membrane proteins. 189 A nn u.

Annulus Fibrosus Cells Interact With Neuron-Like Cells to Modulate Production of Growth Factors and Cytokines in Symptomatic Disc Degeneration

Study Design. We hypothesized that AF/neuron interactions during annular injury were involved in neovascularization and nerve ingrowth, the pathologic hallmarks of symptomatic disc degeneration. Objective. To identify growth factors and inflammatory cytokines related to AF/neuron interactions using in vitro model. Summary of Background Data. Discogenic pain is the chronic intractable pain initiated by tears in the outer annulus fibrosus (AF); this is a unique structure with free nerve endings at outer one-third, located beside dorsal root ganglia. The relationship between AF and neuron cells in annular injury has not been extensively investigated. Methods. Human AF cells were cocultured with a retinoic acid (RA)-treated SH-SY5Y human neuroblastoma cell line (neuron-like cells). Conditioned media from cells cultured alone or in coculture were assayed for growth factors and inflammatory cytokines using enzyme-linked immunosorbent assays. The responses of the neuron-like cells, the AF cells, and the cocultured group to IL-1&bgr;/TNF-&agr; were compared using the same outcome measures. Results. RA-treated SH-SY5Y cells showed significant neurite outgrowth on the 7th day; this is a typical morphologic finding of neuron-like cells. Neuron-like cells produced vascular endothelial growth factor (VEGF) and IGF-1 under basal conditions and dose-dependently secreted small amounts of IL-8 in response to TNF-&agr;. Coculturing enhanced the secretion of VEGF, TGF-&bgr;1, and &bgr;-NGF, and suppressed the production of IGF-1. VEGF in the coculture group and the AF cells was downregulated by IL-1&bgr;/TNF-&agr; stimulation. IL-1&bgr;/TNF-&agr; stimulation enhanced the production of large amounts of IL-6 and IL-8 from AF cells; IL-1&bgr; produced a greater response than TNF-&agr;. The neuron-like cells did not produce detectable amounts of IL-6 or IL-8. Conclusion. These studies suggest that AF cells are involved in an inflammatory reaction and that the interactions between AF and neuron-like cells enhance the production of growth factors responsible for neovascularization and nerve ingrowth. AF injury has the potential to initiate neovascularization/nerve ingrowth and an inflammatory reaction through the interactions of AF and neural tissues.
Pitx2 prevents susceptibility to atrial arrhythmias by inhibiting left-sided pacemaker specification

Atrial fibrillation (AF), the most prevalent sustained cardiac arrhythmia, often coexists with the related arrhythmia atrial flutter (AFL). Limitations in effectiveness and safety of current therapies make an understanding of the molecular mechanism underlying AF more urgent. Genome-wide association studies implicated a region of human chromosome 4q25 in familial AF and AFL, ≈150 kb distal to the Pitx2 homeobox gene, a developmental left–right asymmetry (LRA) gene. To investigate the significance of the 4q25 variants, we used mouse models to investigate Pitx2 in atrial arrhythmogenesis directly. When challenged by programmed stimulation, Pitx2null+/− adult mice had atrial arrhythmias, including AFL and atrial tachycardia, indicating that Pitx2 haploinsufficiency predisposes to atrial arrhythmias. Microarray and in situ studies indicated that Pitx2 suppresses sinoatrial node (SAN)-specific gene expression, including Shox2, in the left atrium of embryos and young adults. In vivo ChIP and transfection experiments indicated that Pitx2 directly bound Shox2 in vivo, supporting the notion that Pitx2 directly inhibits the SAN-specific genetic program in left atrium. Our findings implicate Pitx2 and Pitx2-mediated LRA-signaling pathways in prevention of atrial arrhythmias.
Frequency of the metabolic syndrome in adult type 2 diabetics presenting to Pakistan Institute of Medical Sciences.

OBJECTIVE To determine the frequency of metabolic syndrome in both genders, in a limited adult type 2 diabetic population presenting to Pakistan Institute of Medical Sciences, Islamabad. METHODS This was a cross sectional study conducted in a tertiary care teaching hospital. During the six months of study period, 106 adult type 2 diabetics were examined and evaluated for the presence of metabolic syndrome according to the ATP-III criteria. Asian standards for the waist circumference were used. RESULTS Out of 106 patients, 91 (85.8%) had metabolic syndrome of whom 95% were females. Abdominal obesity was present in 91% females and 86% males. Low HDL levels were present in all females and 83% males. Seventy eight percent females and 63% males had elevated levels of triglycerides. Hypertension was present in 68% and 73% females and males respectively. CONCLUSION This study showed a very high prevalence of the metabolic syndrome in type2 diabetic population. Females were more affected than males in all respects.
Prion protein (PrPc) immunocytochemistry and expression of the green fluorescent protein reporter gene under control of the bovine PrP gene promoter in the mouse brain

Expression of the cellular prion protein (PrPc) by host cells is required for prion replication and neuroinvasion in transmissible spongiform encephalopathies. As a consequence, identification of the cell types expressing PrPc is necessary to determine the target cells involved in the cerebral propagation of prion diseases. To identify the cells expressing PrPc in the mouse brain, the immunocytochemical localization of PrPc was investigated at the cellular and ultrastructural levels in several brain regions. In addition, we analyzed the expression pattern of a green fluorescent protein reporter gene under the control of regulatory sequences of the bovine prion protein gene in the brain of transgenic mice. By using a preembedding immunogold technique, neuronal PrPc was observed mainly bound to the cell surface and presynaptic sites. Dictyosomes and recycling organelles in most of the major neuron types also exhibited PrPc antigen. In the olfactory bulb, neocortex, putamen, hippocampus, thalamus, and cerebellum, the distribution pattern of both green fluorescent protein and PrPc immunoreactivity suggested that the transgenic regulatory sequences of the bovine PrP gene were sufficient to promote expression of the reporter gene in neurons that express immunodetectable endogenous PrPc. Transgenic mice expressing PrP‐GFP may thus provide attractive murine models for analyzing the transcriptional activity of the Prnp gene during prion infections as well as the anatomopathological kinetics of prion diseases.

Comparative pathobiology of beta-amyloid and the unique susceptibility of humans to Alzheimer's disease

The misfolding and accumulation of the protein fragment A β is an early and essential event in the pathogenesis of Alzheimer's disease (AD). Despite close biological similarities among primates, humans appear to be uniquely susceptible to the profound neurodegeneration and dementia that characterize AD, even though nonhuman primates deposit copious A β in senile plaques and cerebral amyloid-β angiopathy as they grow old. Since the amino acid sequence of A β is identical in all primates studied to date, we asked whether differences in the properties of aggregated A β might underlie the vulnerability of humans and the resistance of other primates to AD. In a comparison of aged squirrel monkeys (Saimiri sciureus) and humans with AD, immunochemical and mass spectrometric analyses indicate that the populations of A β fragments are largely similar in the two species. In addition, A β -rich brain extracts from the brains of aged squirrel monkeys
Strategic-Decision Quality in Public Organizations: An Information Processing Perspective

This study draws on information processing theory to investigate predictors of strategic-decision quality in public organizations. Information processing theory argues that (a) rational planning practices contribute to strategic-decision quality by injecting information into decision making and (b) decision makers contribute to strategic-decision quality by exchanging information during decision making. These assumptions are tested upon 55 Flemish pupil guidance centers. Rational planning practices are operationalized as strategic planning, performance measurement, and performance management. Information exchange by decision makers during decision making is operationalized as procedural justice of the decision-making process. Results suggest that procedural justice, strategic planning, and performance management contribute to strategic-decision quality while performance measurement does not.
The Zinc Concentration in the Diet and the Length of the Feeding Period Affect the Methylation Status of the ZIP4 Zinc Transporter Gene in Piglets

High doses of zinc oxide are commonly used in weaned pig diets to improve performance and health. Recent reports show that this may also lead to an imbalanced zinc homeostasis in the animal. For a better understanding of the regulatory mechanisms of different zinc intakes, we performed a feeding experiment to assess potential epigenetic regulation of the ZIP4 gene expression via DNA methylation in the small intestine of piglets. Fifty-four piglets were fed diets with 57 (LZn), 164 (NZn) or 2,425 (HZn) mg Zn/kg feed for one or four weeks. The ZIP4 expression data provided significant evidence for counter-regulation of zinc absorption with higher dietary zinc concentrations. The CpG +735 in the second exon had a 56% higher methylation in the HZn group compared to the others after one week of feeding (8.0·10-4 < p < 0.035); the methylation of this CpG was strongly negatively associated with the expression of the long ZIP4 transcripts (p < 0.007). In the LZn and NZn diets, the expression of the long ZIP4 transcripts were lower after four vs. one week of feeding (2.9·10-4 < p < 0.017). The strongest switch leading to high DNA methylation in nearly all analysed regions was dependent on feeding duration or age in all diet groups (3.7·10-10 < p < 0.099). The data suggest that DNA methylation serves as a fine-tuning mechanism of ZIP4 gene regulation to maintain zinc homeostasis. Methylation of the ZIP4 gene may play a minor role in the response to very high dietary zinc concentration, but may affect binding of alternate zinc-responsive transcription factors.
Efficacité des traitements phytosanitaires contre les ravageurs et maladies de quatre variétés de tomate au Centre de la Côte d’Ivoire

L’evolution des populations d’insectes ravageurs et des maladies, ainsi que leur incidence sur la recolte et l’efficacite des traitements chimiques ont ete etudiees a la Station Experimentale du Foro-Foro de l’Institut des Savanes (ex-IDESSA). Deux fongicides Manate 80 % et Peltar Flo et deux insecticides Decis 12 EC (deltamethrine) et Systoate (dimethoate) ont ete experimentes en 9 combinaisons de traitements sur quatre varietes de tomate (Rossol, Petomech, Avinash-2 et IDSA07-390). Les observations et mesures ont porte principalement sur le niveau des populations et l’incidence des mouches blanches, des chenilles, des maladies fongiques et virales et sur le rendement de quatre varietes de tomate. L’etude a montre que la deltamethrine et le dimethoate sont efficaces contre les mouches blanches et les chenilles. Quant aux chenilles, la noctuelle (Spodoptera sp.) s’avere bien plus importante aussi bien par le nombre de chenilles que par les degâts causes sur les fruits. Les maladies mycologiques observees en vegetation ont revele, principalement, les pourritures du collet, les degâts d’alternariose et de stemphyliose. Le manebe semble bien controler ces maladies. Les pertes de recoltes dues aux insectes et champignons ont ete evaluees a 23,7 % et 32,5 %.

RENDIMIENTO DEL MAÍZ DE TEMPORAL Y SU RELACIÓN CON LA PUDRICIÓN DE MAZORCA

En el Valle Toluca-Atlacomulco, Estado de Mexico, Mexico, se cultivan 250 000 ha con maiz, principalmente con criollos de las razas adaptadas a esta region. En el presente estudio se evaluo la susceptibilidad de 25 genotipos de maiz a la pudricion de mazorca causada por Fusarium spp. y su relacion con dias a fl oracion femenina, acame y rendimiento de grano. Los genotipos fueron evaluados en campo durante 2004 en tres localidades bajo condiciones de temporal e infeccion natural de la enfermedad, bajo un diseno de bloques completos al azar y cuatro repeticiones por localidad. El analisis de datos se efectuo como una serie de experimentos. Las diferencias entre variedades e hibridos y entre Palomero Toluqueno y Cacahuacintle con Conico y Chalqueno explicaron el mayor porcentaje de variacion entre genotipos para las cuatro caracteristicas mencionadas. La variedad Ixtlahuaca (testigo) fue mas tardia que Palomero Toluqueno y mas precoz que los otros genotipos; presento porcentajes de acame y pudricion de mazorca inferiores a Palomero Toluqueno, Cacahuacintle y Chalqueno; sin embargo, el acame fue superior al de los hibridos de otras razas. Ixtlahuaca obtuvo mayor rendimiento que Palomero y Cacahuacintle, pero fue superada por Chalqueno, por hibridos Conico-Chalqueno y los de otras razas como AS- 722, Condor y H-40. El analisis genotipo x caracteristica indico que Palomero Toluqueno fue mas precoz y de menor rendimiento. Cacahuacintle, la mas susceptible al acame y pudricion de mazorca causada por Fusarium. Conico y Chalqueno tuvieron mayor resistencia al acame y pudricion de mazorca y mayor rendimiento que Palomero Toluqueno y Cacahuacintle. Los hibridos comerciales Condor, H-33, H-40, H-44 y H-90E mostraron mayor rendimiento y baja pudricion de mazorca; esta se correlaciono positivamente con el acame y ambas caracteristicas se correlacionaron negativamente con rendimiento.
A Late Woodland red ocher burial cache from Madison County, Ohio

An isolated human burial was discovered on a private property in Madison County, Ohio in the spring of 2009. The remains were recovered by the Ohio Bureau of Criminal Investigations and sent to The Ohio State University for analysis. We report the results of a generic descriptive analysis of the assemblage and remains. The individual was a robust young adult male, and the assemblage seemed typical of a terminal Archaic or Early Woodland period (1500–500 B.C.) deposit; however, a 14C AMS analysis run on collagen from a rib of the burial yielded an estimated age of 1520–1370 BP (A.D. 430–580). The dating result indicates that there is much potential variability in the archaeology of central Ohio that is not well accounted for by current classification systems.
Hippocampus and striatum: Dynamics and interaction during acquisition and sleep‐related motor sequence memory consolidation

While several models of memory consolidation have previously associated hippocampal activity with declarative memory, there is now increasing evidence that the hippocampus also plays a crucial role in procedural memory. Here, we review recent human functional neuroimaging studies demonstrating that the hippocampus is involved in the acquisition and sleep‐related consolidation of procedural memories, and motor sequence‐based skills in particular. More specifically, we present evidence that hippocampal activity and its functional interactions with other brain structures, particularly competition with the striatum, contribute to initial learning of sequential motor behavior. Interestingly, these early cerebral representations in the hippocampus and striatum, which may interact through the prefrontal cortex, can even predict subsequent sleep‐related memory consolidation processes. We propose that sleep can reorganize the activity within, as well as the functional interactions between, these structures, ultimately favoring overnight performance enhancement. Finally, we conclude by offering insights into the respective roles of these structures in procedural memory consolidation processes. We argue that, in the context of motor sequence memory consolidation, the hippocampal system triggers subsequent sleep‐dependent performance enhancement whereas the striatal system is involved in the maintenance of the motor behavior over time. © 2013 Wiley Periodicals, Inc.
Walking Back to Happiness? Modern Pilgrimage and the Expression of Suffering on Spain's Camino de Santiago

This article examines the experiences of walkers along the Spanish Camino de Santiago pilgrimage. It explores their journeys as exercises in narrative adjustment, social practices, and somatic experiences of a crippling loss of control over the course of their lives. Using a phenomenological method of descriptions, the article argues that mobility is a trope that expresses existential issues in a bodily idiom. It draws attention to the value of inter-subjective experience as a potential source of existential mobility, one that finds metaphorical expression in the slow daily rhythms structuring pilgrims' journeys and that impacts on the researcher as much as the pilgrims.
