Application of On-line HPLC-CD Detection in Separation and StructureElucidation of Tricyclic Cephalosporine Oxaanalogues with ChromaneMoiety

In recent years, compounds containing in skeleton chromane moiety have gained the huge interest of medicinal chemists. Chromane and its derivatives are important intermediates and interesting building-blocks in organic synthesis and drug design. Beyond the most well-known derivatives of vitamin E with antioxidant properties [1], flavones, 3-benzylidene, 4-chromanone, or chiral dihydrocoumarin derivatives have attracted much attention due to their pharmacological and physiological activities such as anti-inflammatory, HIV replication inhibition and antioxidant [2, 3]. A group of phenylalanine and 2-chromanone derivatives was found to be the β-lactamase substrates [4]. Inhibition of those enzymes plays the crucial role in the discovery and development process of new active β-lactam antibacterial agents [5]. Together with the isolation from nature or synthetic studies of new active compounds their chemical analysis calls for access to modernized methods for in-depth structural characterization. The boundaries in this field lie in an improvement of detection sensitivity of small quantities, separation of complex mixtures of compounds, and in the elucidation of the stereostructure of components [6]. The assignment of absolute configuration (AC) of organic molecules still remains as one of the most important challenges in modern organic chemistry.
Design and Evaluation of a Professional Identity Development Program for Pharmacy Students

Objective. To design and evaluate a professional identity program (PIP) based on self-determination theory (SDT) for entering Bachelor of Pharmacy (BPharm) students. Methods. The PIP, which featured autonomy-supportive teaching approaches, was delivered as 10 workshops that were integrated into existing pharmacy courses over the first four semesters (2 years) of the BPharm program. The program was evaluated using a student satisfaction survey and two previously validated tools for measuring professional identity (MCPIS-9) and motivation to study pharmacy (Pharm-S). Nonparametric statistical techniques were used to compare students’ scores before and after introducing the PIP. Results. Students responded positively to the introduction of the PIP in the pharmacy program. Based on survey responses, the students valued opportunities to engage in activities and discussions related to professional development and identity formation. Student scores on the motivation-based tool (Pharm-S) increased by the end of the first year of participation in the PIP, indicating an increase in student autonomy levels. There was no change in students’ scores on the professional identity measure (MCPIS-9) after the first year. Conclusion. The use of SDT-based instruction in professional identity education resulted in increased levels of autonomy in pharmacy students, indicating a transition to more intrinsic levels of motivation. This has the potential to positively impact student professional identity and future professional practice.
A Minimum-Cost Modeling Method for Nonlinear Industrial Process Based on Multimodel Migration and Bayesian Model Averaging Method

With increasing drastic market competition, establishing an accurate and reliable performance prediction model for control and optimization at a minimum cost is a growing trend in industrial production. This article proposes a minimum-cost modeling method to develop the performance prediction model of a new nonlinear industrial process. The core idea of this approach is to migrate the useful information on multiple old and similar processes to develop a new process model. A multimodel migration strategy is proposed to migrate the useful information by combining the existing nonlinear process models and take full advantage of minimum data from the new nonlinear process. In order to obtain a set of optimal weights for combining the multiple old and similar process models, the Bayesian model averaging method is employed to estimate the contributions of each available old nonlinear process model to the new nonlinear process model. Moreover, a further experiment used nested Latin hypercube design (NLHD) to gather the necessary minimum data on the new nonlinear process for model migration. Finally, we apply the proposed minimum-cost modeling method to the new multistage centrifugal compressor in the combined cycle power plant, and the results show that the proposed method can develop an accurate compressor model at a minimal cost in terms of the amount of new process data. Note to Practitioners—Process optimal control and condition monitoring are vital for the stability and economic operation of industrial processes, and the basis of them is to quickly establish an accurate and reliable process performance prediction model. Traditional methods for developing process performance prediction models often require a large amount of complex calculations and rich process data, which is time- and cost-consuming. In particular, these methods focus only on the current process to be modeled, while ignoring the existing and similar process information, wasting process information. This article presents a minimum-cost modeling method for nonlinear industrial processes, which can make full use of information on multiple similar existing processes to assist the modeling of a new process to reduce the modeling cost of the new process. Specifically, a multimodel migration strategy including Bayesian model averaging is designed to migrate useful information from similar processes to the new process. The nested Latin hypercube design (NLHD) is employed to collect the necessary minimum data on the new nonlinear process. By applying the proposed approach to the industrial nonlinear process, it is possible to achieve the accurate performance prediction model with minimal new process data.

Microgrid Infrastructure Compendium Analysis with a Model Creation Tool and Guideline Based on Machine Learning Techniques

A microgrid (MG) is an electric power distribution system that may provide a suitable ecosystem for distributed generation. Detailed information about the infrastructure layer in MG projects is available, so this study aimed to propose a compendium and a model creation guideline for MGs. The aggregated information based on 1618 MGs was summarized into different tables and analyzed based on various parameters. Two MG infrastructure model creation tools were developed. First, a simple guideline was created based on the information in the tables, and then a machine learning tool based on decision trees was proposed that generates more accurate MG models using two main inputs: latitude and the segment in which they operate.
Cardiovascular effects of prolonged milrinone inhalation in patients with pulmonary hypertension undergoing mitral valve replacement

Context Inhaled milrinone has short-acting selective pulmonary vasodilator effect. Aims The aim of the study was to investigate the cardiovascular effects of prolonged inhalation of nebulized milrinone on patients with pulmonary hypertension undergoing mitral valve replacement. Settings and design This is a controlled, randomized, double-blinded study. Patients and methods Forty patients were divided into two groups: the milrinone group and the control group. The milrinone group received milrinone nebulization before cardiopulmonary bypass (CPB) as the loading dose at 50 mg/kg, followed by a maintenance dose of 0.5 mg/kg/min, which was continued for 2 h after tracheal extubation. The control group received an equivalent volume of 0.9% sodium chloride. The measured and calculated variables included heart rate, mean arterial blood pressure, central venous pressure, mean pulmonary artery pressure (mPAP), pulmonary capillary wedge pressure, cardiac index (CI), pulmonary vascular resistance (PVR), and systemic vascular resistance. The time points of measurements and calculations were as follows: at T 0 - after anesthesia induction and before sternotomy; at T 1 - 20 min after CPB cessation; at T 2 - 1 h after CPB cessation; at T 3 - 3 h after CPB cessation; at T 4 - 1 h after tracheal extubation; and at T 5 - 1 h after milrinone discontinuation. The duration of CPB and time of tracheal extubation were recorded. Results The milrinone group showed significant reduction in mPAP (T 2 to T 4 readings), pulmonary capillary wedge pressure (T 3 reading), and PVR (T 2 to T 4 readings), increase in CI (T 3 and T 4 readings), and shorter CPB duration and tracheal extubation time. Conclusion Prolonged inhalation of nebulized milrinone proved to be feasible in patients with pulmonary hypertension (PAH) undergoing mitral valve replacement. It decreased PVR and mPAP while increasing CI. This helped shorter CPB duration and earlier tracheal extubation.

The use of visual support strategies (PECS and Visual Schedule) for autism with weak criteria in communication can help children become better in developing communication potential.
Investigation of the natural history of Equine Encephalitis Viruses with radiofrequency telemetry for detection of subclinical disease patterns

Neither licensed vaccines nor antiviral therapeutics with proven efficacy exist to protect against the equine encephalitis viruses (EEVs), specifically Eastern, Western, and Venezuelan Equine Encephalitis Viruses (EEEV, WEEV, and VEEV, respectively). Due to rigorous ethical, regulatory, and scientific considerations, animal models that can faithfully demonstrate aspects of clinical disease must be established for testing of countermeasure candidates. Such models must satisfy the Animal Rule promulgated and enforced by the United States Food and Drug Administration and capture key aspects of equine encephalitis virus presentation in humans, especially with respect to encephalitic disease, whose manifestations include fever and neurological signs. This study seeks to establish and study a model of human equine encephalitis virus infection via the aerosol route in the nonhuman primate, the cynomolgus macaque (Macaca fascicularis) with a focus on the natural history of disease through examination of radiofrequency electrocardiography data, and evaluates the feasibility of the use of such data to prognosticate severe disease courses which include encephalitis. Twelve nonhuman primate subjects, grouped four per type of equine encephalitis virus, were challenged with aerosol exposures of the alphaviruses in various doses. The following electrocardiography metrics compose a core set of variables suited to the characterization of disease rendered by EEVs: HR, PCt, P-Width, PR-I, QRS, QRSA, QT-I, R-H, and RR-I. Frequency spectrum analysis conducted on these metrics can be used to distinguish different periods of disease, if not distinguish between diseases, and Poincare plots of heart rate variability data can be used to track the progression of illness. The public health significance of this work rests in its contributions to disease detection to aid in vaccine and therapeutic development for both the prevention of infectious disease and the mitigation of risk posed by potential biological weapons attacks. Finally, improved clinical disease detection through RF telemetry and other markers will abet the surveillance function of public health.

Anterior cervical discectomy and fusion solely with peek cages in multilevel cervical spondylotic radiculomyelopathy: single center clinical experience with 58 consecutive patients

Aim of this study was to evaluate the efficacy and safety of fusion solely with polyetheretherketone (PEEK) cages without plates and autogenous bone graft to provide fusion in multilevel cervical spondylosis in selected cases. 58 patients with cervical discogenic disorders in 3-4 levels (38 and 20 patients respectively) underwent multilevel anterior cervical discectomy and fusion (ACDF) operations with PEEK cages for a total of 194 levels. Minimum follow up was 24 months (24-48) postoperatively. Outcome had been established in combination with the evaluation of cervical lordosis, fusion rates and neurological improvement that was assessed by Japanese Orthopedic Association (JOA) scoring system. They were assessed by radiographs, computerized tomography and magnetic resonance imaging studies. Clinical outcomes were based on the issues including length of hospital stay, blood loss, complication rates and functional outcomes. 38 patients underwent three-level, 20 patients underwent four-level operations. Fusion rate was 89.2%. Significant improvement in the JOA scores was recorded postoperatively, and Ishihara Curvature Index (ICI) was preserved. In the follow-up period, no cage migration was experienced and reoperation was not required except for one who later underwent corpectomy and anterior fusion. ACDF with the use of PEEK cages without plates proved to yield good clinical outcome and comfortable postoperative course for the patients with acceptable fusion rates.
Management diversity and human resources policies and practices in high education institutions

This article investigates the perception of the workers in High Education Institutions (HEIs) in the State of Santa Catarina (SC), it is based on six Human Resources policies, under the perspective of generational diversity. The research’s nature was quantitative, based on description and survey. Data collection was carried out using the scale of the Human Resources Policies and Practices (EPPRH), validated in Brazil by Demo in 2008. A total of 409 workers from eleven HEIs participated in the study. Comparatively, results were very similar, with averages close in the items investigated, comparing the generations baby boomers, X, Y e Z. It can be sustained that in the HR policies and practices in HEIs all generations usually converge on the thinking and perceptions related to them. The interviewees showed indifference or unawareness about the policies that were studied, since their existence and/or effectiveness were not expressly perceived, it would be advisable for HEI to re-think their proposals, models of implementation and dissemination of these themes. Further research is suggested in view of differences in the belonging of HEI workers, intersectionalities of diversity, and qualitative understanding of responses.
Did the Communists Contribute to China’s Rural Growth?

The communist revolution brought unprecedented changes to China. Yet there is no consensus on its role in the history of China’s modern economic growth. We investigate whether local communist party membership affected developmental outcomes from 1957–78 (the Maoist period) and 1978–85 (the reform period). Focusing on Sichuan, China’s most populous province, we use the Long March as an instrument to tease out causal effects. We find that counties with more communist members made larger strides in educational attainment, road construction, and agricultural mechanization during the Maoist period. However, these counties recorded faster output growth only after 1978. Our findings provide empirical support to field studies conducted by sociologists and historians who argue that the communists improved the organizational infrastructure in China’s countryside. Furthermore, we highlight the futility of solving collective action problems without heeding private incentives.

THE ELEVATION OF LIVER ENZYMES DUE TO HEPATITIS B VACCINE

Hepatitis B virus infection described as the second carcinogen factor after smoking by the World Health Organization (WHO) is a global public health problem (1). It was reported that 15-40% of HBV infected patients would develop cirrhosis, liver failure, or hepatocellular carcinoma and 500 000 to 1.2 million people die of HBV infection annually (2). Because of the high HBV-related morbidity and mortality, the global disease burden of HB is substantial. Hepatitis B viral infection is a preventable disease. Three main strategies have been approved to be effective in preventing HBV infection. They are behavior modification, passive immunoprophylaxis, and active immunization. The implementation of mass HBV immunization program is recommended by the WHO since 1991 (3).
