Study on Impact of Iron and Folic Acid on the Plasma Trace Minerals in Pregnant Anemic Women

Iron deficiency anemia is one of the causes that lead to significant mortality and morbidity among pregnant women and fetus. The present study was undertaken to explore oral iron supplementation can modify the metal contents in pregnant anemic women. Iron and folic acid supplementations was given to 500 anemic women (mild = 200, moderate = 200, and severe = 100) and 100 age matched non-anemic controls daily for 100 days. Blood index values and plasma trace minerals were estimated as per standard protocols. Haemoglobin and ferritin levels were found significantly increased (p < 0.001) in anemic and control subjects after treatment. Moreover, the serum transferring receptor levels and total iron binding capacity were found significantly decreased in all treated groups. Iron (Fe), zinc (Zn) and copper (Cu) levels were found increased (p < 0.01) after oral iron supplementation groups. Moreover, selenium (Se) manganese (Mn) and were found to be decreased in all treated groups. Data provides the conclusion that iron and folic acid supplementation recovered the essential trace minerals, except manganese, which may lead to various complications including peroxidation of vital body molecules resulting in increased risk for pregnant women as well as fetus.     

Urinary Urea,Uric Acid and Hippuric Acid as Potential Biomarkers in Multiple Sclerosis Patients

Urine is a proven source of metabolite biomarkers and has the potential to be a rapid, noninvasive, inexpensive, and efficient diagnostic tool for various human diseases. Despite these advantages, urine is an under-investigated source of biomarkers for multiple sclerosis (MS). The objective was to investigate the level of some urinary metabolites (urea, uric acid and hippuric acid) in patients with MS and correlate their levels to the severity of the disease, MS subtypes and MS treatment. The urine samples were collected from 73 MS patients-48 with RRMS and 25 with SPMS- and age matched 75 healthy controls. The values of urinary urea, uric acid and hippuric acid in MS patients were significantly decreased, and these metabolites in SPMS pattern showed significantly decrease than RRMS pattern. Also showed significant inverse correlation with expanded disability status scale and number of relapses. Accordingly, they may act as a potential urinary biomarkers for MS, and correlate to disease progression.     

Robust simultaneous fault detection and control for a class of nonlinear stochastic switched delay systems under asynchronous switching

This paper concerns the simultaneous fault detection and control (SFDC) problem for a class of nonlinear stochastic switched systems with time-varying state delay and parameter uncertainties. The switching signal of detector/controller unit (DCU) is assumed to be with switching delay, which results in the asynchronous switching between the subsystems and DCU. By constructing a switching strategy depending on the state and switching delays, new sufficient conditions expressed by a set of linear matrix inequalities (LMIs) is derived to design DCU gains. This problem is formulated as an H_∞ optimization problem and both mean square exponential stability and fault detection of augmented system are considered. A numerical example is finally exploited to verify the effectiveness and potential of the achieved scheme.

Training Transfer and Transfer Motivation: The Influence of Individual,Environmental, Situational,Training Design,and Affective Reaction Factors

The purpose of this study is to examine the effects of individual, environmental, training design, and affective reaction factors on training transfer and transfer motivation. To determine the relationship between these factors and their influence on training transfer and to test the model, the researchers collected data from employees in the Malaysian banking sector. Structural equation modeling with Amos 16 was used to test the model and determine the relationship. The study suggested that training stakeholders should manage the training program effectively. Transfer is maximized when trainees have social support, high performance self‐efficacy, and transfer motivation. Stakeholders (e.g., trainers, trainees, supervisors, and peers) are important to the training transfer process, as are learner readiness, trainee reaction, instrumentality, and training retention. This study revealed that perceived content validity and transfer design work together and influence the trainee's performance self‐efficacy. In other words, if trainers want to improve the performance self‐efficacy level of trainees, they need to explain how the trainee can transfer the learned skills at the workplace and make sure the content of the training is similar to the actual job. The main objective of training programs is to align the employee's expertise with organizational goals. Organizations can achieve their desired objectives only when employees transfer the learned skills on the job. Unfortunately, employees often transfer only a small percentage of skills they have learned in training. To effectively manage their training programs, organizations need to identify and focus on the factors that resist effective training transfer.     

The INSPIRE Project: Using the ‘Unknown’ to Co-construct a Training Course on Humanistic Counselling in Afghanistan

This article details a collaborative project between the University of Strathclyde (UK) and the University of Herat (Afghanistan). The aim was to co-construct a model of training, based on humanistic approaches, in order to enhance counselling services in Afghanistan and to establish counselling training at the University of Herat. Two groups of participants received 120 h training each. In February 2014 a selected group received a further training for trainers. Strengths and limitations of this project are explored as well as its impact on the Afghan community and further developments for counselling in this context.     

The Quality of Pre-service Science Teachers’ Argumentation: Influence of Content Knowledge

Research exploring the possible link between quality of argumentation and content knowledge is not straightforward. Some studies suggest a positive relationship (e.g. Dawson & Schibeci in J Biol Educ 38(1):7–12, 2003) while others do not (e.g. Zohar & Nemet in J Res Sci Teach 39:35–62, 2002). This study examined the possible relationship between pre-service science teachers’ (PSTs) lines of argument regarding genetic cloning issues and their knowledge of the related content. In the research, pre-service teachers were divided into groups according to the results of a conceptual understanding test on genetic cloning, and were categorized as high, middle and low achievers. After introducing three socio-scientific scenarios (relating to genetic cloning) with the intention of prompting lines of argumentation, the PSTs then participated in semi-structured interviews with the research team. It was revealed that there is not a significant relationship between the quality of socio-scientific argumentation among PSTs and their knowledge of content in the domain of cloning. Explanations for these results are discussed in light of the related literature and with reference to the interviews.     

Adult humans’ understanding of support relations: an up-linkage replication

In an up-linkage replication, three experiments examined adult humans’ folk physics, i.e., their naturally occurring and spontaneous understanding of the physical world, using a violation of expectation (VOE) task and stimuli similar to those used to study chimpanzees’, monkeys’, and rooks’ folk physics. Unlike what has been reported with nonhuman primates, adult humans did not look longer at physically impossible than possible events, though they did rate the physically impossible events as more interesting and novel than the possible events. These results underscore that behavior during a VOE experiment has many possible causes, only one of which may be a subject’s folk physics.
