Strong halo-femoral traction with wide posterior spinal release and three dimensional spinal correction for the treatment of severe adolescent idiopathic scoliosis.

BACKGROUND Many investigators advocate anterior release combined with halo-femoral traction and posterior fusion when treating stiff thoracic curves in patient with adolescent idiopathic scoliosis (AIS). But the anterior operations often induce severe complications. Some surgeons choose posterior-only surgery with halo-femoral traction, posterior wide release and correction. But to the best of our knowledge, there are only rare prospective studies on these posterior-only surgeries for AIS patients who have a rigid curve more than 80° and flexibility less than 35%. METHODS Sixty-four AIS patients were recruited from September 2006 to June 2009. All patients had rigid curves and underwent spinal correction. They were randomly divided into group A (combined anteroposterior surgery) and group B (posterior-only surgery). Images and scoliosis research society-22 questionnaire (SRS-22) scores were performed pre- and post-operation and during follow-up visits. The operation time, blood loss, hospital days, and hospital charges were compared between the two groups. RESULTS These patients were followed for an average of 37.5 months (range, 24 - 65 months). No serious complications were observed. There were no significant differences between the two groups in gender, age, preoperative radiographic data, or preoperative SRS-22 score. The average operation time, blood loss, hospital days and hospital charges in group B were less than those in group A. The SRS-22 score in group B was better than in group A at post-operation and at final follow-up. CONCLUSIONS In AIS with a rigid curve more than 80° and flexibility less than 35%, strong halo-femoral traction with wide posterior spinal release and three dimensional spinal correction can provide better SRS-22 scores, comparable curve correction, shorter operation time, less blood loss, shorter hospital stays and lower charges when compared to combined anterior and posterior surgery.
Growth Performance of Rahmani and F1 Cross (Chios x Rahmani) Lambs under the Environmental Conditions of Upper Egypt

This study was carried out in Animal Production Department Farm, Faculty of Agriculture, Al–Azhar University during three consecutive production years (2002, 2003 and 2004). This study aimed to evaluate some productive and reproductive traits in Rahmani sheep and F1 cross with Chios rams (½ C ½ R). A total of 200 Rahmani ewes were bred, and produced 144 lambs (However, 140 lambs born alive and 4 lambs died after birth) of which 116 were raised to weaning. The effect of genetic groups, sex of lambs, year of lambing and season of lambing on birth weight of lambs were not significant, while, type of birth and age of dam had a significant (P<0.01 or P<0.05) effects on birth weight of lambs. The crossbred lambs (½ C ½ R) were heavier at birth than purebred Rahmani lambs; Male lambs were heavier than female ones in their birth weight. Also, single born lambs were heavier than twin lambs in their birth weight, and lambs born in summer were, on the average 0.13 kg, heavier than those born in winter at birth. Lambs born by ewes of 4 years–old or more had the heaviest birth weight. Genetic groups had a highly significant (P<0.01) effect on weaning weight and preweaning daily gain of lambs, while, sex of lambs, type of birth, year of lambing, season of lambing and age of dam had no significant effect on weaning weight of lambs. Genetic groups, sex of lambs, type of birth, year of lambing, season of lambing and age of dam had no significant effect on body weight at 6, 9 and 12 months of age or on daily gain at all periods studied . However, the F1 crossbred (½ C ½ R) expressed heavier weights than purebred Rahmani at all periods studied, male lambs were heavier than females, and single born lambs were heavier than lambs born as twins in all body weights studied. Also lambs born in summer was heavier than that of winter ones.
Hunger perceptions and satiety responses among normal-weight bulimics and normals to a high-calorie, carbohydrate-rich food

Synopsis The hunger perceptions and satiety responses to a high-calorie, carbohydrate-rich food among 10 normal-weight females who met the DSM-III criteria for bulimia were compared with 10 normal-weight females who denied a current or past history of eating or weight disorders. As indicated by self-report responses on the Hunger–Satiety Questionnaire, bulimics did not differ from the normals in their perceptions of hunger sensations. Differences, however, were detected the responses following eating. Most notably, the bulimics reported feelings of irritability, nervousness, tenseness and depression which persisted 30 minutes later. These findings and directions for future research are discussed.
Patient Shifting as a Response to Medicare Prospective Payment

The Medicare Prospective Payment System (PPS) regulations provide hospitals with strong incentives to discharge patients sooner. It seems reasonable to assume that a large number of these discharged patients may require posthospital care in long-term care facilities (LTCFs). Such shifting of patients from hospitals to LTCFs would be evidenced by a sicker population of patients requiring more extensive and intensive treatments in the post-PPS period. The purpose of this study was to determine the extent to which patient shifting occurred after implementation of the PPS regulations. Data were collected from the medical records of 353 patients admitted to 10 LTCFs in Georgia both before and after the PPS was implemented. Comparisons of the two groups indicated no significant differences in LTCF admitting diagnoses, numbers of patients dying or being readmitted to the hospital within 30 days of LTCF admission, prognosis, or rehabilitative potential. The groups differed to a statistically significant extent on three treatment and health status variables: patients in the post-PPS group were more likely to be incontinent of bladder, to have nasogastric tubes, and to be on dietary supplements. These differences may suggest the beginning of a trend to shift heavier care patients into LTCFs. As a whole, however, the results of this study indicated limited shifting of patients from hospitals to LTCFs in Georgia during the first year after implementation of the PPS regulations.
Aerodynamic force generation and power requirements in forward flight in a fruit fly with modeled wing motion

SUMMARY Aerodynamic force generation and power requirements in forward flight in a fruit fly with modeled wing motion were studied using the method of computational fluid dynamics. The Navier-Stokes equations were solved numerically. The solution provided the flow velocity and pressure fields, from which the vorticity wake structure and the unsteady aerodynamic forces and torques were obtained (the inertial torques due to the acceleration of the wing-mass were computed analytically). From the flow-structure and force information, insights were gained into the unsteady aerodynamic force generation. On the basis of the aerodynamic and inertial torques, the mechanical power was obtained, and its properties were investigated. The unsteady force mechanisms revealed previously for hovering (i.e. delayed stall, rapid acceleration at the beginning of the strokes and fast pitching-up rotation at the end of the strokes) apply to forward flight. Even at high advance ratios, e.g. J=0.53-0.66 (J is the advance ratio), the leading edge vortex does not shed (at such advance ratios, the wing travels approximately 6.5 chord lengths during the downstroke). At low speeds (J≈0.13), the lift (vertical force) for weight support is produced during both the down- and upstrokes (the downstroke producing approximately 80% and the upstroke producing approximately 20% of the mean lift), and the lift is contributed mainly by the wing lift; the thrust that overcomes the body drag is produced during the upstroke, and it is contributed mainly by the wing drag. At medium speeds (J≈0.27), the lift is mainly produced during the downstroke and the thrust mainly during the upstroke; both of them are contributed almost equally by the wing lift and wing drag. At high speeds (J≈0.53), the lift is mainly produced during the downstroke and is mainly contributed by the wing drag; the thrust is produced during both the down- and upstrokes, and in the downstroke, is contributed by the wing lift and in the upstroke, by the wing drag. In forward flight, especially at medium and high flight speeds, the work done during the downstroke is significantly greater than during the upstroke. At advance ratios J≈0.13, 0.27 and 0.53, the work done during the downstroke is approximately 1.6, 2.8 and 4.2 times as much as that during the upstroke, respectively. At J=0 (hovering), the body-mass-specific power is approximately 29 W kg-1; at J=0.13 and 0.27, the power is approximately 10% less than that of hovering; at J=0.40, the power is approximately the same as that of hovering; when J is further increased, the power increases sharply. The graph of power against flying speeds is approximately J-shaped. From the graph of power against flying speeds, it is predicted that the insect usually flies at advance ratios between zero and 0.4, and for fast flight, it would fly at an advance ratio between 0.4 and 0.53.
Potentiation of a primary in vivo antibody response by alloantisera against gene products of the I region of the H-2 complex.

Mice were immunized intravenously with suboptimal numbers (3.5-5 X 10(5)) of sheep erythrocytes together with various anti-Ia antisera or with sheep erythrocytes alone, and the primary IgM and IgG plaque-forming cell responses were assayed 6 days later9 A/J (H-2a) mice given 5 X 10(5) sheep erythrocytes together with as little as 0.4 mul of a (129 X A.TH)F1 anti-A.TL (anti-Iak) antiserum developed 2-3 times as many IgM and IGG plaque-forming cells as mice injected with antigen alone or together with various antisera not containing anti-Ia antibodies. Similar results were obtained with BALB/c (H-2d) mice and a (C3H X LG/Ckc)F1 anti-C3H. OH (anti-Iad) antiserum plus sheep erythrocytes. In the case of the anti-Iad antiserum, the potentiating activity could be absorbed with C3H. OH (Id) but not C3H(Ik) spleen cells, demonstrating that the active antibodies were specific for the Id region. Antiserum to I-Jk subregion-coded determinants was tested in A/J (I-Jk) mice and found to also potentiate 2- to 3-fold the plaque-forming cell response to suboptimal erythrocyte immunization. This antiserum [(BIO.A(3R) X DBA/2)F1 anti-B10. (5R)] failed to potentiate responses in BALB/c (I-Jd) mice, as expected on a genetic basis. The potentiating antibodies could be removed by absorption with B10.BR (I-Jk) but not B10 (I-Jb) spleen cells, also confirming the I-J specificity of the activity. The interference of anti-I-J antibodies with T lymphocyte suppressor mechanisms is prposed as a possible explanation for this phenomenon.
Alcohol, smoking, social and occupational factors in the aetiology of cancer of the oral cavity, pharynx and larynx

A case‐control study of 374 patients with primary epithelial cancers of the oral cavity, oro‐ and hypopharynx, and larynx is reported, the controls being patients with selected other cancers, matched for age and sex. Of all eligible patients, 93 % were interviewed. Increased risks were seen with alcohol consumption and, less strongly, with smoking, which for all sites could be adequately fitted by either a multiplicative or an additive model. However, the site‐specific relationships were different, alcohol consumption being significantly associated only with oral cavity, pharyngeal and extrinsic laryngeal tumours, and smoking only with intrinsic laryngeal tumours. Increased risks were associated with low socio‐economic status, the unmarried state, and poor dental care. No significant associations were seen with specific occupational exposures.
The Effect of Feeding Different Levels of Moringa oleifera Leaf Meal on the Performance and Some Blood Parameters of Broilers

The study was carried out at the farm of the College of Animal Production of Science and Technology,at Hillat Kuku, during the period of 7-4-2014 to 7-6-2014.The aim of the study was to evaluate Moringa oleifera leaf meal (MLM) as alternative cheap source of protein in the diets of Arbaicher grower broiler chicken breed and also the study was aimed to find out the effect of Moringaoleifera on body weight of broilers and on blood parameters. Two hundred chickens, aged 21 days were used; the chickens were divided into four groups; a control group and three experimental groups. The four experimental groups provided consecutively with%0, 2%%4 and 5%M. oleifera leave /kg of feed daily for 21 days (Finisher diet), which was added to their daily feed, and the control group was fed a diet without M. oleifera. The results showed significant variations in the final body and daily weight gain. Group Dbirds recorded the highest values for packed cell volume(PCV), hemoglobin concentration(Hb), and red blood cells (RBCs), values were 42.70%, 4.310/m ×and16.2 respectively. Group C have recorded the highest values for mean cell hemoglobin concentration (MCHC). Significant differences were noticed for the red blood cells (RBCs) count, hemoglobin (Hb) and MCHC values among groups while no significant differences were observed between the control andgroup D. The mean values for PCV in group C and D were high while birds on the control diet had the least PCV value of 23.7 %. Similarly birds of group B had the highest RBC value of 2.73 ± 1.13 x106/m. and highest HB value of 17.32 + 0.70, the least values were obtained by group C birds.
Induction of apoptosis in vitro by the 17-kDa nonstructural protein of infectious bursal disease virus: possible role in viral pathogenesis.

Infectious bursal disease virus (IBDV) causes severe immunodeficiency in young chickens by destroying the precursors of antibody-producing B cells in the bursa of Fabricius. It has been shown that IBDV infection induces apoptosis in chicken embryo and tissue culture cells. We previously reported that an IBDV mutant lacking the expression of 17-kDa nonstructural (NS) protein exhibited decreased apoptotic effects in cell culture as compared to the parental IBDV, suggesting that the NS protein may be involved in induction of apoptosis. Here, we report that the NS protein of IBDV alone is capable of inducing apoptosis in cell culture. Transfection of chicken B-lymphocyte cell line (RP9) and chicken embryo fibroblast cells with a plasmid DNA, containing the NS protein gene under the control of the immediate-early promoter-enhancer region of human cytomegalovirus, induced programmed cell death in both cell lines. Apoptosis changes, such as chromatin condensation, DNA fragmentation, and the appearance of apoptotic nuclear bodies, were observed in cell cultures 48-h posttransfection. As reported earlier, the mutant IBDV grew to lower titers with slower replication kinetics and lower cytopathogenicity when compared to that of the parental virus. Here, we demonstrate that the mutant virus is closely associated with cells and its yield from the supernatant was approximately 30-fold lower than the wild-type due to increased cell association, indicating a deficiency in lysis of virus-infected cells. Taken together, our results indicate that the NS protein of IBDV is highly cytotoxic, which brings about the release of the viral progeny from cells, and thus play an important role in viral pathogenesis.
Rerum cognoscere causas: Part II—Opportunities generated by the agency/structure debate and suggestions for clarifying the social theoretic position of system dynamics

This is the second half of a two-part paper dealing with the social theoretic assumptions underlying system dynamics. In the first half it was concluded that analysing system dynamics using traditional, paradigm-based social theories is highly problematic. An innovative and potentially fruitful resolution is now proposed to these problems. In the first section it is argued that in order to find an appropriate social theoretic home for system dynamics it is necessary to look to a key exchange in contemporary social science: the agency/structure debate. This debate aims to move beyond both the theories based only on the actions of individual human agents, and those theories that emphasise only structural influences. Emerging from this debate are various theories that instead aim to unite the human agent view of the social realm with views that concentrate solely on system structure. It is argued that system dynamics is best viewed as being implicitly grounded in such theories. The main conclusion is therefore that system dynamics can contribute to an important part of social thinking by providing a formal approach for explicating social mechanisms. This conclusion is of general significance for system dynamics. However, the over-arching aim of the two-part paper is to increase the understanding of system dynamics in related disciplines. Four suggestions are therefore offered for how the system dynamics method might be extended further into the social sciences. It is argued that, presented in the right way, the formal yet contingent feedback causality thinking of system dynamics should diffuse widely in the social sciences and make a distinctive and important contribution to them.

Single peaked CO emission line profiles from the inner regions of protoplanetary disks

Context. Protoplanetary disks generally exhibit strong line emission from the CO fundamental v = 1–0 ro-vibrational band around 4.7 μm. The lines are usually interpreted as being formed in the Keplerian disk, as opposed to other kinematic components of the young stellar system. Aims. This paper investigates a set of disks that show CO emission line profiles characterized by a single, narrow peak and a broad base extending to >50 km s −1 , not readily explained by just Keplerian motions of gas in the inner disk. Methods. High resolution (R = 10 5 ) M-band spectroscopy has been obtained using CRIRES at the Very Large Telescope in order to fully resolve fundamental ro-vibrational CO emission line profiles around 4.7 μm. Results. Line profiles with a narrow peak and broad wings are found for 8 disks among a sample of ∼50 disks around T Tauri stars with CO emission. The lines are very symmetric, have high line/continuum ratios and have central velocity shifts of < 5k m s −1 relative to the stellar radial velocity. The disks in this subsample are accreting onto their central stars at high rates relative to the parent sample. All 8 disks show CO emission lines from the v = 2 vibrational state and 4/8 disks show emission up to v = 4. Excitation analyses of the integrated line fluxes reveal a significant difference between typical rotational (∼300–800 K) and vibrational (∼1700 K) temperatures, suggesting that the lines are excited, at least in part, by UV-fluorescence. For at least one source, the narrow and broad components show different excitation temperatures, but generally the two component fits have similar central velocities and temperature. Analysis of their spatial distribution shows that the lines are formed within a few AU of the central star. Conclusions. It is concluded that these broad centrally peaked line profiles are inconsistent with the double peaked profiles expected from just an inclined disk in Keplerian rotation. Models in which the low velocity emission arises from large disk radii are excluded based on the small spatial distribution. Alternative non-Keplerian line formation mechanisms are discussed, including thermally and magnetically launched winds and funnel flows. The most likely interpretation is that the broad-based centrally peaked line profiles originate from a combination of emission from the inner part (
What Do They Want? Motivating Consumers to Disclose Personal Information to Internet Businesses

An increasing number of Internet businesses are seeking consumer information in order to target their products or services at the right consumers. To overcome information privacy, or the desire of consumers to control the disclosure and subsequent use of personal information, Internet businesses need to motivate consumers to voluntarily disclose their personal information. This paper focuses on the issue of information disclosure by consumers. Based on a synthesis of literature from several disciplines, it offers a framework of seven motivators that can induce consumers to disclose their personal information. Through comprehensive conceptual and empirical validation processes, it presents a 32-question instrument to measure these motivators. This instrument can facilitate future efforts at developing theories on information privacy and can help Internet businesses to better understand how best to solicit personal information from consumers. Implications for research and practice are discussed.
Different Effects Of β‐Adrenoceptor Desensitization On Inhibitory Actions In Guinea‐Pig Trachealis

1. To determine the inhibitory effects of agents that pass through and bypass β‐adrenoceptors under conditions of tolerance to β‐adrenoceptor agonists, we examined the inhibition by the β‐adrenoceptor agonists forskolin and theophylline against contraction induced by methacholine (MCh) after exposure to higher concentrations of a β‐adrenoceptor agonist for a long time in guinea‐pig tracheal smooth muscle, using isometric tension records.
