As part of the Sam Higginbottom University of Agriculture, Technology and Sciences in Prayagraj, this experiment was carried out at the Small Animal Lab which is part of the research unit. We investigated the “economic cost of including probiotics in the feed of caged broilers”. We used a total of 96 day-old chicks and were randomly assigned four groups of 24 chicks (T0, T1, T2, and T3) and eight replicates each, these groups. T0 control group was fed the (BD), T1 was fed Bacillus coagulans at 40 ppm in BD, T2 was fed B. subtilis at 50 ppm in BD, and T3 was fed B. licheniformis and B. coagulans 20 ppm in BD. After a 35-days trial period, an analysis of the economic effects of the probiotics supplementation was calculated. The results revealed a decrease in FCR as birds achieved more weight, leading to increased body weight and resulting in a higher price per kg. Adding probiotics to the feed doesn’t increase the variable cost than the control group. It was found that the maximum profit was obtained in T3 (Rs. 5771.32), T0 (Rs. 5297.3), and T2 (Rs. 5074.92), whereas the T1 group had the least revenue. Mixing probiotics in poultry feed increases profit without much affecting the production cost.

Authors: Barambones Oscar , Garrido Aitor J. , Garrido Izaskun 
Published: July 2007

AbstractIn this paper, a speed estimation and control scheme of an induction motor drive based on an indirect field‐oriented control is presented. On one hand, a rotor speed estimator based on an artificial neural network is proposed, and on the other hand, a control strategy based on the sliding‐mode controller type is proposed. The stability analysis of the presented control scheme under parameter uncertainties and load disturbances is provided using the Lyapunov stability theory. Finally, simulated results show that the presented controller with the proposed observer provides high‐performance dynamic characteristics and that this scheme is robust with respect to plant parameter variations and external load disturbances.

Transient monoclonal expansion of CD8+/CD57+ T‐cell large granular lymphocytes after primary cytomegalovirus infection

Published: July 2007

AbstractLymphocytosis associated with viral infection is generally polyclonal or oligoclonal. In this article, we describe a case of transient monoclonal CD8+/CD57+ T‐cell lymphocytosis with large granular lymphocyte (LGL) morphology occurring after primary CMV infection and review cases of virus‐associated monoclonal CD8+ T‐cell expansions reported in the literature. Several clinical features shared by virus‐associated monoclonal CD8+ T‐cell expansions suggest the reactive nature of the lymphocytosis. Based on this, our case report and those reported in the literature support the notion that T‐cell receptor clonality per se is not necessarily indicative of malignancy. These observations further corroborate the need for a close follow‐up before assigning the diagnosis of LGL leukemia to individuals developing monoclonal CD8+ T‐cell expansions. Am. J.

Published: July 2007

AbstractVenous thromboembolism (VTE) is a major US health problem. However, the total number of US inpatients who are at risk for VTE is unknown. Our objective was to estimate the number of US acute‐care hospital inpatients who were at risk for VTE according to criteria established by the Seventh American College of Chest Physicians (ACCP) Consensus Conference on Antithrombotic and Thrombolytic Therapy guidelines for VTE prevention. Using the 2003 Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project (HCUP), patient diagnoses and procedures were examined to identify major surgery patients (age ≥ 18 years, length of hospital stay ≥ 2 days) and medical patients (age ≥ 40 years, length of hospital stay ≥ 2 days). ACCP guidelines were used to estimate the number of surgical and medical patients at risk of developing VTE. Of an estimated 38,220,659 discharges in 2003, 7,786,390 (20%) were surgical inpatients; 44% of which were at low risk for VTE, while 15%, 24%, and 17% were at moderate, high, and very high risk for VTE, respectively. Of the remaining 15,161,586 medical patients, 7,742,419 (51%) met ACCP VTE risk criteria. Over 12 million patients, comprising 31% of US hospital discharges in 2003, were at risk of VTE. Given the existence of internationally‐accepted evidence‐based guidelines for prevention of VTE, research is required to establish if this patient population is receiving recommended VTE prophylaxis.

Inclusive interface design for seniors: Image‐browsing for a health information context
Authors: Given Lisa M. , Ruecker Stan , Simpson Heather , Sadler Elizabeth (Bess) , Ruskin Andrea 
Published: July 2007

AbstractThis study explores an image‐based retrieval interface for drug information, focusing on usability for a specific population—seniors. Qualitative, task‐based interviews examined participants' health information behaviors and documented search strategies using an existing database (www.drugs.com) and a new prototype that uses similarity‐based clustering of pill images for retrieval. Twelve participants (aged 65 and older), reflecting a diversity of backgrounds and experience with Web‐based resources, located pill information using the interfaces and discussed navigational and other search preferences. Findings point to design features (e.g., image enlargement) that meet seniors' needs in the context of other health‐related information‐seeking strategies (e.g., contacting pharmacists).
Neural tube defects, micronutrient deficiencies, and Helicobacter pylori: A new hypothesis
Authors: Felkner Marilyn , Suarez Lucina , Liszka Beata , Brender Jean D. , Canfield Mark 
Published: July 2007

AbstractBACKGROUND: Previous findings for the Texas Neural Tube Defects Project suggested that while maternal access to nutrients is adequate, bioavailability of nutrients to the fetus is compromised in NTD‐affected pregnancies. Helicobacter pylori could cause nutrient loss to the fetus. Folate, B12, and ferritin are depleted in H. pylori infection; these same deficiencies are related to NTD risk. METHODS: Using H. pylori IgG ELISA Test System, we tested for H. pylori serum antibodies in participants in the population‐based case‐control study component of the Texas Neural Tube Defect Project conducted along the Texas‐Mexico border. Case‐women had pregnancies affected by NTD (anencephalus, spina bifida, encephalocele) and resided and delivered in one of the 14 Texas‐Mexico border counties from 1995 through 2000. Control‐women were study area residents delivering normal live births during the same period. RESULTS: Of 225 case‐ and 378 control‐women, 103 cases and 156 controls provided questionnaire and H. pylori antibody data. H. pylori seropositivity was modestly associated with NTD‐affected pregnancies (OR 1.4; 95% CI: 0.8–2.4). ORs of 2.0 or greater were seen in women younger than age 25 and with less than 7 years education. CONCLUSIONS: Our findings intimate that H. pylori could play a role in NTD causation in certain populations. While results did not provide compelling support for this proposal, subgroup findings prompt us to advocate an evaluation of this hypothesis in developing nations among populations with higher prevalence of H. pylori, marginal nutrient intake, and young childbearing age.

Published: July 2007

AbstractMany alternative strategies to immobilize and stabilize enzymes have been investigated in recent years for applications in biosensors. The entrapment of enzymes within silica‐based nanospheres formed through silicification reactions provides high loading capacities for enzyme immobilization, resulting in high volumetric activity and enhanced mechanical stability. Here we report a strategy for chemically associating silica nanospheres containing entrapped enzyme to a silicon support. β‐galactosidase from E. coli was used as a model enzyme due to its versatility as a biosensor for lactose. The immobilization strategy resulted in a three‐dimensional network of silica attached directly at the silicon surface, providing a significant increase in surface area and a corresponding 3.5‐fold increase in enzyme loading compared to enzyme attached directly at the surface. The maximum activity recovered for a silicon square sample of 0.5 × 0.5 cm was 0.045 IU using the direct attachment of the enzyme through glutaraldehyde and 0.16 IU when using silica nanospheres. The immobilized β‐galactosidase prepared by silica deposition was stable and retained more than 80% of its initial activity after 10 days at 24°C. The ability to generate three‐dimensional structures with enhanced loading capacity for biosensing molecules offers the potential to substantially amplify biosensor sensitivity. Biotechnol.

Published: July 2007

AbstractHyaluronic acid (HA) coated drug carriers (HCDCs) were successfully synthesized by chemical conjugation method for targeted delivery of doxorubicin (DOX) as a prototype anticancer drug to CD44 expressed human breast cancer cell. From XPS analysis, the HCDCs by conjugation methods demonstrated the superior HA fixation amount and colloidal stability compared with the nanoparticles by nanoprecipitation. The cytotoxicity of the HCDCs formulation accessed by the MTT assay against the higher CD44 expressed cell line (MDA‐MB‐231) and lower CD44 expressed cell line (ZR‐75‐1) human breast cancer cell lines demonstrated that the HCDCs formulation exhibited excellent tumoricidal effect and their affinity to cancer cells was predominant. The in vitro drug release profile of the HCDCs showed sustained release behavior and after 14 days, 80% of the encapsulated DOX was released due to a high release rate of DOX from HCDCs. We synthesized that HCDCs have therapeutic potentials of cancer as a target specific fashion by increasing the tumoricidal efficacy of targeted cancer cells while reducing their cytotoxicity of non‐targeted cells to minimize the side effect.

Explaining the impact of ISO 14001 on emission performance: a dynamic capabilities perspective on process and learning
Authors: Russo Michael V. 
Published: July 2007

AbstractI draw upon the dynamic capability model to explore how new process standards influence the ability of manufacturing facilities to improve environmental performance by reducing toxic emissions. The process standards studied are the ISO 14001 environmental management standards, in use since 1996. Hypotheses are developed to account for how early adoption of ISO 14001 and experience with the standards influence emission levels. These hypotheses are tested using a large sample of electronics manufacturing facilities and data from 1996 through 2001. Consistent with theoretical expectations, analyses show that being one of the first facilities to adopt ISO 14001 was associated with lower emissions. Further, a separate effect is due to experience: the longer a facility operated under ISO 14001, the lower its emissions. The paper discusses the implications of these results for theory and policy development. Copyright © 2007 John Wiley & Sons, Ltd and ERP Environment.
Fungiform taste bud degeneration in C57BL/6J mice following chorda‐lingual nerve transection
Authors: Guagliardo Nick A. , Hill David L. 
Published: July 2007

AbstractTaste buds are dependent on innervation for normal morphology and function. Fungiform taste bud degeneration after chorda tympani nerve injury has been well documented in rats, hamsters, and gerbils. The current study examines fungiform taste bud distribution and structure in adult C57BL/6J mice from both intact taste systems and after unilateral chorda‐lingual nerve transection. Fungiform taste buds were visualized and measured with the aid of cytokeratin 8. In control mice, taste buds were smaller and more abundant on the anterior tip (<1 mm) of the tongue. By 5 days after nerve transection taste buds were smaller and fewer on the side of the tongue ipsilateral to the transection and continued to decrease in both size and number until 15 days posttransection. Degenerating fungiform taste buds were smaller due to a loss of taste bud cells rather than changes in taste bud morphology. While almost all taste buds disappeared in more posterior fungiform papillae by 15 days posttransection, the anterior tip of the tongue retained nearly half of its taste buds compared to intact mice. Surviving taste buds could not be explained by an apparent innervation from the remaining intact nerves. Contralateral effects of nerve transection were also observed; taste buds were larger due to an increase in the number of taste bud cells. These data are the first to characterize adult mouse fungiform taste buds and subsequent degeneration after unilateral nerve transection. They provide the basis for more mechanistic studies in which genetically engineered mice can be used. J. Comp. Neurol. 504:206–216, 2007. © 2007 Wiley‐Liss, Inc.

Published: July 2007

AbstractMotor deficit severity and the potential for recovery in patients with brain injury depend on the integrity of descending corticofugal projections. Clinical assessment of these conditions following subtotal brain trauma requires a comprehensive understanding of the anatomical structures involved in the lesion as well as those structures that are spared. To assist in this endeavor, we investigated motor fiber organization in the crus cerebri of the cerebral peduncle (ccCP) in the rhesus monkey. Fibers originating from the arm representations of the primary (M1), supplementary (M2), rostral cingulate (M3), caudal cingulate (M4), dorsolateral pre‐ (LPMCd) and ventrolateral pre‐ (LPMCv) motor cortices were studied. The projections from the frontal and cingulate motor cortices formed descending longitudinal bundles that occupied the medial three‐fifths of the ccCP at superior and middle levels. Although considerable overlap characterized these corticofugal projections, a general topography was discernable. Fibers from M1 and M4 occupied the central subsector of the ccCP, and fibers from M3 resided medially. The main distribution of LPMCd, LPMCv, and M2 fibers occupied the centromedial region and overlapped extensively. Progressing inferiorly, all fiber bundles in the central and centromedial sectors gradually extended medially, and overlap increased. A common location of fiber passage occurred at the midbrain‐pontine isthmus where all of the fiber bundles overlapped. Our findings indicate that the widespread distribution of corticofugal motor projections may account for the favorable levels of motor recovery that accompany subtotal midbrain injury. At superior and mid‐levels of the ccCP anteromedial lesions may disrupt projections from M3, whereas anterolateral lesions may disrupt projections from M1 and M4. Fibers from M2, LPMCv, and LPMCd may be compromised to some degree in both situations. The compact and commixed nature of motor fiber organization at inferior levels and the midbrain‐pontine isthmus suggests a vulnerable region of passage for comprehensive disruption of frontal and cingulate corticofugal projection fibers.

Midline and intralaminar thalamic connections with the orbital and medial prefrontal networks in macaque monkeys
Authors: Hsu David T. , Price Joseph L. 
Published: July 2007

AbstractAlthough the midline and intralaminar thalamic nuclei (MITN) were long believed to project “nonspecifically,” they are now known from rat studies to have restricted connections to the prefrontal cortex. This has not been studied thoroughly in primates, however, and it is not known how MITN are associated with the “orbital” and “medial” prefrontal networks. This study examined the connections of MITN in cynomolgus monkeys (Macaca fascicularis). Experiments with retrograde and anterograde tracer injections into the orbital and medial prefrontal cortex (OMPFC) showed that MITN are strongly connected with the medial prefrontal network. The dorsal nuclei of the midline thalamus, including the paraventricular (Pa) and parataenial nuclei (Pt), had heavy connections with medial network areas 25, 32, and 14c in the subgenual region. Areas 13a and 12o, which are associated with both networks, were strongly connected with the Pt and the central intermedial nucleus, respectively. Otherwise, orbital network areas had weak connections with MITN. Anterograde tracer injections into the dorsal midline thalamus resulted in heavy terminal labeling in the medial prefrontal network, most notably in areas ventral to the genu of the corpus callosum (25, 32, and 14c), but also in adjacent areas (13a and 13b). Retrograde tracer injection into the dorsal midline labeled similar areas. The medial network, particularly the subgenual region, is involved in visceral and emotional control and has been implicated in mood disorders. The strong connections between the subgenual cortex and the Pa provide a pathway through which stress signals from the Pa may influence these prefrontal circuits. J. Comp.

Synthesis of general impedance with simple dc/dc converters for power processing applications
Authors: Liu J. C. P. , Tse C. K. , Poon N. K. , Pong M. H. , Lai Y. M. 
Published: July 2007

AbstractA general impedance synthesizer using a minimum number of switching converters is studied in this paper. We begin with showing that any impedance can be synthesized by a circuit consisting of only two simple power converters, one storage element (e.g. capacitor) and one dissipative element (e.g. resistor) or power source. The implementation of such a circuit for synthesizing any desired impedance can be performed by (i) programming the input current given the input voltage such that the desired impedance function is achieved, (ii) controlling the amount of power dissipation (generation) in the dissipative element (source) so as to match the required active power of the impedance to be synthesized. Then, the instantaneous power will be automatically balanced by the storage element. Such impedance synthesizers find a lot of applications in power electronics. For instance, a resistance synthesizer can be used for power factor correction (PFC), a programmable capacitor or inductor synthesizer (comprising small high‐frequency converters) can be used for control applications.

Heat Transfer in Electric Arc Chamber of Linear Plasmatron
Authors: Anshakov A. S. , Lukashov V. P. , Fokin V. N. 
Published: July 2007

AbstractClassification and performance capability of electric are linear plasmatrons are presented. The results of investigation into convective and radiative heat transfer in the discharge channel of a plasmatron are reported. The radiative heat transfer dominates both in the structure of heat losses and in the formation of discharge volt‐ampere characteristic at the initial region of the flow. Relations to calculate heat losses by radiation are given. Radiative convective interaction at the arc boundary is shown to play a substantial role for high‐current discharges stabilized by axial vortex gas flow. It is shown that the calculation of convective heat transfer at the turbulent region of the flow may be carried out by flow averaged parameters.

Published: July 2007

AbstractIn the paper radiative‐convective heat transfer in electric arc flowed through by Ar in the discharge chamber is studied. The equation system for heat, mass and momentum transfer in boundary layer approximation is considered, and the turbulence model with radiation pulsation and electrodynamic values is suggested.By solution of the equation system with the help of finite differences method distributions of temperature, heat flows and turbulent transfer coefficients over chamber length were obtained. The radiation and turbulence influence on the electric arc characteristics is analysed.
