Proprioception in the anterior cruciate deficient knee

Proprioception was quantified in a group of patients who had documented complete ACL tears. Threshold to detection of passive change in position of the knee was measured using a well-described test. Eleven pa tients with arthroscopically proven complete ACL tears and findings consistent with moderate to severe anter olateral rotatory instability were tested. Testing was done within the 30° to 40° range of knee flexion. Patients were blindfolded and the injured and uninjured knees were tested in random sequence so that the normal knee could serve as an internal control. Testing was also done in a blind manner, i.e., the examiner did not know which knee had been injured. An age- matched control group underwent identical testing. Po tentially significant variables such as age, time from injury, and degree of rehabilitation as measured by thigh circumference and isokinetic testing of the knee were included in a multivariate analysis. Control subjects demonstrated virtually identical threshold values between their two knees, the mean variation being less than 2%. The test group, however, showed a significantly higher mean threshold value for the injured versus the noninjured knee (P < 0.01), the mean variation being over 25%. Multivariate analysis demonstrated that changes recorded in the propriocep tion of the injured knee were attributable to the loss of the ACL rather than to other variables. Patients who have complete ACL tears and moderate to severe rotatory instability may also experience a decline in proprioceptive function of their knee.
The Relationship Between Motor Proficiency and Physical Activity in Children

OBJECTIVES. Youth with better motor abilities may find it easier to be physically active and may be more likely to engage in physical activity compared with peers with poorer motor competence. The purpose of this study was to examine the relationship between motor proficiency and physical activity in 8- to 10-year-old children. Self-efficacy toward physical activity was also assessed. METHODS. Sixty-five children (34 girls and 31 boys) were studied. Children's physical activity was assessed by the Manufacturing Technologies Incorporated/Computer Science and Applications Incorporated model 7164 accelerometer, and their motor proficiency was determined by the Bruininks-Oseretsky Test of Motor Proficiency. The Children's Self-Perceptions of Adequacy in and Predilection for Physical Activity scale measured children's self-perceptions of adequacy in performing and desire to participate in physical activities. RESULTS. Children's motor proficiency was positively associated with activity counts and percentage of time in moderate and moderate-to-vigorous intensity physical activity and inversely related to percentage of time in sedentary activity. Children in the greatest quartile of motor proficiency were the most physically active compared with children with lower levels of motor proficiency who had similar levels of physical activity. Children with greater standardized BMI were less physically active, more sedentary, and had poorer motor proficiency compared with children with a lower standardized BMI. Children's Self-Perceptions of Adequacy in and Predilection for Physical Activity scores were positively associated with Bruininks-Oseretsky Test of Motor Proficiency standard score for boys. Children's motor proficiency explained an additional 8.7% of the variance in physical activity in multiple linear regression after controlling for factors that may influence physical activity. CONCLUSIONS. Motor proficiency is positively associated with physical activity and inversely associated with sedentary activity in children, but there may be a threshold of motor proficiency above which children may be the most physically active. Children's motor proficiency may be an appropriate target for increasing physical activity in youth.
Dynamic output feedback control synthesis for stochastic time-delay systems

This article deals with the dynamic output feedback control synthesis problem for Itô-type stochastic time-delay systems. Our aim is to design a full order dynamic output feedback controller to achieve the desired control objectives. We will formulate the controller design problem as an H ∞ optimisation problem in the mean-square sense. The main contributions of this article are as follows: (i) for stochastic systems, the design of a controller with multiple objectives can be addressed without employing a unique Lyapunov function; (ii) using an inequality technique and Finsler Lemma, we provide convex controller synthesis conditions described by linear matrix inequalities (LMIs). Some examples are presented to show the effectiveness of the developed theoretical results.
Are the Wavelet Transforms the Best Filter Banks for Image Compression?

Maximum regular wavelet filter banks have received much attention in the literature, and it is a general conception that they enjoy some type of optimality for image coding purposes. To investigate this claim, this article focuses on one particular biorthogonal wavelet filter bank, namely, the 2-channel 9/7. As a comparison, we generate all possible 9/7 filter banks with perfect reconstruction and linear phase while having a different number of zeros at for both analysis and synthesis lowpass filters. The best performance is obtained when the filter bank has 2/2 zeros at for the analysis and synthesis lowpass filters, respectively. The competing wavelet 9/7 filter bank, which has 4/4 zeros at , is thus judged inferior both in terms of objective error measurements and informal visual inspections. It is further shown that the 9/7 wavelet filter bank can be obtained using gain-optimized 9/7 filter bank.
Determinants of Parental Discipline Practices: A National Sample From Primary Care Practices

National guidelines urge pediatricians to address discipline as part of anticipatory guidance, yet pediatricians know little about what leads parents to use different discipline approaches. Parents seen in Pediatric Research in Office Settings practices participated in an office-based survey before the well-child visit for children 2 to 11 years old (N = 2134). Parents reported using the following discipline approaches frequently: time-outs (42%), removal of privileges (41%), sent to bedroom (27%), yelling (13%), and spanking (9%). A third of parents believe their discipline approach to be ineffective. This directs the pediatric provider to help families develop effective discipline practices tailored to their context.
Practical approaches of taste masking technologies in oral solid forms

In the pharmaceutical industry, taste masking techniques are applied to prevent active pharmaceutical ingredients exhibiting a bitter and unpleasant taste. The oral administration of bitter drugs through solid dosage forms requires an acceptable degree of palatability, patient tolerance and significant therapeutic value. In the recent years, enormous progress in taste masking technologies has given rise to novel strategies such as fast dissolving dosage forms, chewable tablets and coating of molten materials. Similarly, common technologies applying double coating layers, microencapsulation or even chemical modification have been employed to improve patient compliance. This review endeavours to present the practical technologies and platforms applied for taste masking and indicate the most interesting features of each approach.
Comparison of the Minimally Invasive and Conventional Open Surgery Approach in the Treatment of Lumbar Stenosis: A Systematic Review and a Meta-Analysis.

INTRODUCTION Minimally invasive surgery (MIS) is increasingly used in the treatment of lumbar stenosis. However, it is still not clear if the employment of minimally invasive surgical techniques can achieve superior clinical outcomes compared to standard open laminectomy. MATERIALS AND METHODS An extensive literature review regarding the clinical outcome, safety, and efficiency of MIS and standard open surgery (OS) in the treatment of lumbar stenosis was conducted on Medline, Cochrane, EMBASE, and Google Scholar databases up to 19 August 2016. RESULTS Sixteen studies that enrolled a total of 1580 patients with surgically-indicated lumbar stenosis were identified; 793 patients underwent MIS and 787 patients underwent conventional OS. No significant difference was found in the improvement of Oswestry Disability Index (ODI) (P = 0.718) and operation time (P = 0.322) between patients from different treatment groups. MIS was associated with better visual analogue scale (VAS) for back pain (P = 0.01), shorter length of hospital stay (P <0.001), and lower blood loss (P <0.001). CONCLUSION Our findings indicate that both MIS and standard OS can effectively manage patients with lumbar stenosis and lead to comparable clinical outcomes. Further studies are necessary to evaluate MIS with different types of conventional surgery for lumbar stenosis.
Annular Pustular Psoriasis and Systemic Lupus Erythematosus

A 30-year-olcl woman presented in 1970 with a history of fever, arthralgia, Raynaud's phenomenon, and dyspnea. On examination, she disclosed a butterfly rash, lymphadenopathy, and peritoneal and bilateral pleural effusion. There were hemolytic anemia, thrombocytopenia, and a positive lupus erythematosus (LE) cells test. Systemic LE (SLE) was diagnosed and 30 mg/day prednisone and 150 mg/day azathioprine prescribed. Eventually, she developed nephropathy, which was treated with steroid pulses. In 1985 a palmo-plantar eruption was diagnosed as pustolosis, palmaris, and plantaris (PPP) and, though partially cured with topical steroids, relapsed 4-5 days after every steroid pulse. Eventually, a 2 g/day proteinuria and a diffuse pustular eruption developed. Examination revealed annular, erythematous areas with numerous pustules at their edges and erosions and crusts involving the trunk and lower (Fig. 1) and upper limbs. Head and mucous membranes were spared. Nikolsky's sign was negative. Erythrocyte sedimentation rate ranged from 65 to 109 mm/hour and proteinuria from 4 to 12 g/dl. C3 was 70 mg/dl (normal values, 88-177) and C4 was 13 mg/dl (normal, 15-45). Antinuclear antibodies were >1:320 with a homogeneous pattern. Absent were anti-dsDNA, anti-ENA, and anti-SSA antibodies. HLA A3 11 B35 CW 4 and DR 4 W53 DQ W1 were found at typing. Histopathology of two annular lesions showed a subcorneal accumulation of neutrophils and cellular debris (Fig. 2) with a typical Kogo's spongiform pustule in the underlying acanthotic epidermis (Fig. 3). No acantholytic cells were seen. The upper dermal vessels showed endothelial swelling and luminal obliteration with a polymorphous infiltrate and signs of leukocytoclasia (Fig. 4). Direct immunofluorescence of both lesions showed granular deposits of C3 at the dermoepidermal junction, IgM fluorescent bodies in the
Diabetes and Cancer

Epidemiologic evidence suggests that cancer incidence is associated with diabetes as well as certain diabetes risk factors and diabetes treatments. This consensus statement of experts assembled jointly by the American Diabetes Association and the American Cancer Society reviews the state of science concerning 1) the association between diabetes and cancer incidence or prognosis, 2) risk factors common to both diabetes and cancer, 3) possible biologic links between diabetes and cancer risk, and 4) whether diabetes treatments influence risk of cancer or cancer prognosis. In addition, key unanswered questions for future research are posed.
Self-tuning algorithms for high-performance bandpass switched-capacitor ΣΔ modulators

Switched-capacitor high-frequency bandpass /spl Sigma//spl Delta/ modulators could suffer from capacitor mismatch, finite opamp dc gain, and finite opamp bandwidth. These problems make the notch frequency and the quality factor of the zeros of the noise transfer function to deviate from their nominal values, strongly affecting the modulator dynamic range (DR). In order to avoid this situation, two sampled-data algorithms have been developed which allow to self-calibrate the bandpass /spl Sigma//spl Delta/ modulators. They use 3500 gate and 0.043 mm/sup 2/ area and consume power only when they are active, while, when the system is on, they are off and do not interfere with standard operation. The validity of the proposal is demonstrated by a silicon prototype in which the proposed solution allows to guarantee a 75-dB DR performance also under worst case conditions. In the particular case, it allows for the recovery of 3 dB in the SNR for the 200-kHz FM band (from 73 to 76 dB).
The course of psychological distress following threatened and actual conjugal bereavement

Synopsis We measured multiple dimensions of distress among spouses (N = 440) of patients hospitalized for serious illness or elective surgery and compared the course of distress over 2 years of follow-up among five groups according to whether and when spouses were bereaved. Distress was related to the severity of the patient's illness, the actuality and timing of the bereavement, as well as the gender and age of the respondent.
Influence of the tectal zone on the distribution of synaptic boutons in the brainstem of goldfish

This study investigated whether the topographic differences in the functional properties of the tectal motor map of goldfish are related to particular patterns of connections with downstream structures. With this aim, the distribution of synaptic boutons in the mesencephalic and rhombencephalic structures was studied after discrete injections of the tracer biotinylated dextran amine were placed at separate sites along the tectal anteroposterior axis. Irrespective of the location of the injection site, the boutons were more abundant in the mesencephalon than in the rhombencephalon, and they were located chiefly ipsilaterally all throughout the brainstem. In the mesencephalon, the boutons were found in its ventrolateral reticular formation and, to a lesser extent, in the nucleus of the medial longitudinal fasciculus, the oculomotor and isthmi nuclei, and the torus semicircularis. In the mesencephalic reticular formation, the bouton location was distributed topographically with respect to the injection site. Terminals were also observed in the nucleus of the medial longitudinal fasciculus after injections into anteromedial or middle tectal zones. In the oculomotor nucleus, boutons were present exclusively in the case of the anteromedial injection. In the rhombencephalon, most boutons were found in the superior reticular formation, and their number decreased in the medial and inferior reticular formations. A topographic distribution could be observed within the superior reticular formation, although its density was attenuated compared with that observed in the mesencephalic reticular formation. The domains of synaptic endings on the ipsilateral side were different from those on the contralateral side: The ipsilateral synaptic endings were located more medially. Finally, a few boutons were also found in the vestibulocerebellar area on either the ipsilateral or the contralateral side, depending on the injection site. From these data, the authors conclude that, in goldfish, irrespective of the tectal injection site, the endings are in similar nuclei in the brainstem; however, the distribution of synaptic boutons within such nuclei can be related to the functional properties of each tectal zone.

Conformal slotted waveguide array antenna

A new slotted rectangular waveguide array antenna is introduced, which is constructed on the conformal cylindrical surface. Unlike other slotted waveguide arrays, this array has a beam with a large tilt angle from the broadside of the linear array. The array consists of a waveguide with inclined slots cutting in the narrow wall and a matching load at one end for the traveling wave operation. The antenna is designed and built using the analytical procedure combining with the commercial software. The radiation patterns and gain of the antenna are measured, and the experimental data obtained are compared with the theoretical results.
Effect Of Crude Protein Levels And Follicle Stimulation On Egg Production Of Aged Hens

Summary: The effects of varying levels of crude protein and follicle stimulation were studied on the recovery and performance of one hundred post moulted, aged, Nera Black Hens. Moulting was induced at production capacity of 33.6%. The birds were thereafter randomly assigned to four (4) groups (each of two replicates). Two groups received 16% crude protein (CP) level diets and the other two groups, 32%. One each of the two groups received follicle stimulation, induced by administration of Clomifene citrate (1.5mg/kg) via cathetered 5ml syringe through the 10week experimental period, with feed and water offered ad libitum. Egg production ceased on day 5 of forced moulting. Postmoult menarche and return to pre-moult status had occurred on days 4 and 8 respectively in all the groups. Post-moult hen-day peak production performance was 87.5%, 91.7%, 68.0% and 83.3% for birds assigned to 16% CP diet without follicle stimulation (Group 1 – control), 16% CP diet plus follicle stimulation (Group 2), 32% CP diet without follicle stimulation (Group 3) and 32% CP plus follicle stimulation (Group 4). Post-moult mean weekly production performance was 69.66%; 67.26%; 56.40% and 63.69% for groups 1,2,3 and 4 hens respectively. Follicle stimulation enhanced post-moult production performance especially the hen-day performance in birds on 16% CP diet. Higher protein diet did not per se enhance peak production, post-moult menarche and return to pre-moult status.
Flood modeling and inundation risk evaluation using remote sensing imagery in coastal zone of China

Global climate change has caused sea level rise, and one of the most extremely consequences are the increased frequency and hazards of the storm surge disasters, therefore, how to effectively assess the risk of storm surge disaster is of importance to hazard reduction and mitigation. However, the storm surge forecast models have complex parameters, which computational inefficiency. Traditional large-scale assessment usually takes elevation-area method based on GIS software, which result in large errors. The present study is attempted to: (1) Select proper two-dimensional hydraulic storm surge inundation model. This model not only has the physical realism but simple and efficient. (2)The present study will focus on the method to extract the required surface parameters based on the remote sensing data to integrate remote sensing data into the model. This project aims to provide the theoretical basis and methodologies for flood risk assessment in coastal zone of China.
Modeling in vivo recovery of intracellular pH in muscle to provide a novel index of proton handling: Application to the diagnosis of mitochondrial myopathy

Post‐exercise recovery of intracellular pH (pHi) assessed using phosphorus magnetic resonance spectroscopy has not been previously evaluated in its entirety due to its complex time‐course and missing data points resulting from a transient loss of inorganic phosphate signal. By considering the transition from exercise to recovery as a step function input, pHi recovery was modeled based on the creatine‐kinase equilibrium, and the entire pHi recovery was characterized by calculating the time required for pHi recovery (tpHrec). Applying this methodology, normal subjects showed a strong linear correlation between phosphocreatine (PCr) half‐time and tpHrec (r = 0.90, P < 0.001). In mitochondrial myopathy (MM) patients with weakness in the limb examined, 9/10 had faster pHi recovery relative to PCr recovery; wide normal ranges from a control group which included deconditioned subjects resulted in 7 of those 10 patients having otherwise normal recovery indices. Therefore, modeling pHi recovery allows characterization of the entire pHi recovery and detects altered proton handling in MM patients, including those with otherwise normal recovery indices.

Adsorption-Dissolution Reactions Affecting the Distribution and Stability of CoIIEDTA in Iron Oxide-Coated Sand.

The time-variant chemical behavior of Co[sup II]EDTA (and other metal-EDTA complexes) was investigated in suspensions of iron oxide-coated sand to identify equilibrium and kinetic reactions that control the mobility of Me[sup II]-EDTA complexes in subsurface environments. Batch experiments were conducted to evaluate the adsorption as a function of pH, concentration, and time and to quantify the rate-controlling step(s) of dissolution of the iron oxide by EDTA complexes. Ionic Co[sup 2+] exhibited typical cation-like adsorption, whereas Me[sup II]EDTA adsorption was ligand-like, increasing with decreasing pH. Adsorption isotherms for all reactive species exhibited Langmuir behavior, with site saturation occurring at molar values of <0.5% of Fe[sub tot]. The adsorption of Me[sup II]EDTA enhanced the apparent solubility of the iron oxide phase, which destabilized the Co[sup II]EDTA complex, liberating Co[sup 2+] and Fe[sup III]EDTA. The dissolution rate was an order of magnitude slower at pH 6.5 than at pH 4.5 and was influenced by the re-adsorption of solubilized Fe[sup III]EDTA. Two multireaction kinetic models were developed that each included Langmuir adsorption for Co[sup 2+] and metal-EDTA species but differed in their depiction of the dissolution mechanism (i.e., ligand-versus proton-promoted dissolution). 45 refs., 8 figs., 6 tabs.
Incidence of fractures in a geographically defined population.

STUDY OBJECTIVE--The aim was to describe the population based age and sex specific incidence of fractures at different sites in a large English health district. DESIGN--Recording of fractures was accomplished by a specially constructed outpatient index and by record linkage to hospital inpatient information, for the three years surrounding the 1981 census. SETTING--The fracture index was held by the Department of Community Health in Leicester using data from the fracture clinic at the central large district general hospital, supplemented by hospital inpatient data from Trent Region and the two adjoining regions. PARTICIPANTS--The denominator population was the Leicestershire Health Authority resident population. In the three years, 12,711 fractures amongst males and 10,565 amongst females were recorded. MEASUREMENTS AND MAIN RESULTS--The overall estimated annual incidence of fractures was 100 per 10,000 population for males and 81 per 10,000 population for females. Below the age of 55 years all fractures showed a higher incidence amongst males but amongst the over 55s, there was a consistent fall in the male:female incidence ratio with some sites showing a striking female preponderance. The results also show an apparent age specific temporal increase in incidence at certain fracture sites compared with earlier British data, but fracture incidence figures still suggest lower rates in this country than in North America and some Scandinavian countries. CONCLUSIONS--These findings provide population based incidence data on a major public health problem and are consistent with the major determinants of osteoporosis and increase in falls in postmenopausal women. The temporal and geographical variation in fracture incidence remain to be explained.
