Active prosthetic knees have the capability to provide net positive work, which is required in daily activities like stair and ramp negotiation or sit-to-stand transfers. Adding this capability might help to increase user mobility, safety, and independence. This article summarizes the biomechanical knee requirements for different activities of daily living and critically compares them with the actuator characteristics of state-of-the-art active prosthetic knee joints. As a result of a systematic literature research 22 active prosthetic knee joints were identified...

Saranya Kuppusamy, Kadiyala Venkateswarlu, Mallavarapu Megharaj, Srinithi Mayilswami, Yong Bok Lee
Sites contaminated with chemical pollutants represent a growing challenge, and remediation of such lands is of international concern. Risk-based land management (RBLM) is an emerging approach that integrates risk assessment practices with more traditional site-specific investigations and remediation activities. Developing countries are yet to adopt RBLM strategies for remediation. RBLM is considered to be practical, scientifically defensible and cost-efficient. However, it is inherently limited by: firstly, the accuracy of risk assessment models used; secondly, ramifications of the fact that they are more likely to leave contamination in place; and thirdly, uncertainties involved and having to consider the total concentrations of all contaminants in soils that overestimate the potential risks from exposure to the contaminants...

Antibodies play a crucial role in host defense and are indispensable research tools, diagnostics, and therapeutics. Antibody generation involves binding of genomically encoded germline antibodies followed by somatic hypermutation and in vivo selection to obtain antibodies with high affinity and selectivity. Understanding this process is critical for developing monoclonal antibodies, designing effective vaccines, and understanding autoantibody formation. Prior studies have found that antibodies to haptens, peptides, and proteins evolve from polyspecific germline antibodies...

REVIEW
Panteleimon Ekkekakis
Exercise psychology has yet to produce intervention methods capable of increasing exercise and physical activity behavior in a sustainable manner. This situation is forcing a critical reevaluation of current conceptual models, especially the assumption that behavioral decisions are driven solely by the rational evaluation of information. Like other behavioral sciences, exercise psychology is transitioning to dual-process models that acknowledge the importance of non-reflective processes. Emerging evidence suggests that the pleasure or displeasure experienced during exercise may influence subsequent physical activity...

REVIEW
Calum A Arthur, Nicolas Bastardoz, Robert Eklund
Borrowed from organizational psychology, the concept of transformational leadership has now been applied to a sport context for a decade. Our review covers and critically discusses empirical articles published on this growing topic. However, because the majority of studies used cross-sectional designs and single-source questionnaires to tap what has been a fuzzy construct, current theoretical and methodological issues impede understanding of whether transformational leadership matters for sport outcomes. To make a difference to applied practice and policy, the transformational leadership construct requires a refined definition and stronger empirical tests allowing for robust causal inference...

#6
REVIEW
Christopher Mesagno, Juergen Beckmann
In sport, choking under pressure is a major concern for athletes, coaches and sport psychologists because athletes fail to meet self-imposed performance expectations in critical situations (when it counts the most), which is devastating and embarrassing. Researchers have debated choking under pressure definitions, identified personality characteristics that exacerbate choking outcomes, and examined models to determine mechanisms for choking. Based on these investigations, several interventions to prevent choking have been developed and tested...

Tatiana V Ryba
Despite a long standing assertion that sociocultural domain is one of the factors constituting human psychological phenomena, sport psychological science has only recently begun to examine culture as the principal basis of physical activity and sport participants' behaviour, wellbeing, engagement, and performance outcomes. Emphasizing the centrality of culture in bringing meaning to athlete careers and life projects, I summarise empirical literature explicitly positioned within cultural sport psychology (CSP)...

REVIEW
Helena Jv Rutherford, Linda C Mayes
Addiction remains a significant public health concern that affects multiple generations within families, and in particular the early relationship between parents and their developing child. This article will discuss recent advances in our understanding of the neurobiology of parenting and addiction. Specifically, the discussion will focus on the reward-stress dysregulation model of addicted parenting, which proposes that the dysregulation of stress and reward neural circuits by addiction represents a neurobiological pathway through which to understand how caregiving may be compromised in addicted parents...

REVIEW
Liat Tikotzky
The development of sleep is influenced by complex interactions between biologically driven forces and diverse socio-environmental factors. Among those factors, parents have a critical role. The present review focuses on new studies regarding the links between parenting and the development of sleep in early childhood in the context of a transactional model. Recent findings from longitudinal studies and large cohort studies highlight the contribution of various parenting factors, such as parental bedtime behaviors, parental cognitions, cry tolerance, maternal mood, stress, and the parents' couple relationship, to the development of child sleep...

Quality of life is a valid patient-reported parameter that provides an assessment of treatment need or outcomes complementary to standard clinical measures. Such patient-reported assessments are particularly salient when examining chronic conditions with prolonged treatment trajectories, such as cleft lip and palate. This critical review identifies key questions related to ongoing research on the oral health-related quality of life (OHRQoL) in children with cleft and caregiver well-being. Details of the design and results from 2 longitudinal multicenter studies are presented...

Gestational diabetes mellitus (GD) is a form of insulin resistance triggered during the second/third trimesters of pregnancy in previously normoglycemic women. It is currently estimated that 10% of all pregnancies in the United States show this condition. For many years, the transient nature of GD has led researchers and physicians to assume that long-term consequences were absent. However, GD diagnosis leads to a six-fold increase in the risk of developing type 2 diabetes (T2D) in women and incidence of obesity and T2D is also higher among their infants...

Prospective studies of the potential health consequences of trade and investment treaties, such as the Trans-Pacific Partnership, are critical. These studies can make visible to trade policy-makers the potential negative impacts associated to such treaties and can influence the outcomes of such negotiations. However, few researchers have examined retrospectively the consequences of trade agreements. With more than 400 trade agreements and more than 2000 investment treaties currently in force, researchers have a large corpus of agreements to analyse in order to assess not only their potential impacts on health system and population health, but also their actual impacts...

BACKGROUND: Cystinuria is an inherited disease that results in the formation of cystine stones in the kidney, which can have serious health complications. Two genes (SLC7A9 and SLC3A1) that form an amino acid transporter are known to be responsible for the disease. Variants that cause the disease disrupt amino acid transport across the cell membrane, leading to the build-up of relatively insoluble cystine, resulting in formation of stones. Assessing the effects of each mutation is critical in order to provide tailored treatment options for patients...

PURPOSE: During the first years of life, food preferences are shaped that might last throughout a person's entire life affecting his/her health in the long term. However, knowledge on early feeding habits is still limited for toddlers. Therefore, the goal of the present study was to: (1) assess toddlers' nutrient intake; (2) compare the findings to past studies as well as to national feeding recommendations and (3) identify major food sources for energy and macronutrients. METHODS: A food survey using a 4-day diary was conducted...

In recent studies, miRNAs have been found to be extremely influential in many of the essential biological processes. They exhibit a self-regulatory mechanism through which they act as positive/negative regulators of expression of genes and other miRNAs. This has direct implications in the regulation of various pathophysiological conditions, signaling pathways and different types of cancers. Studying miRNA-disease associations has been an extensive area of research; however deciphering miRNA-miRNA network regulatory patterns in several diseases remains a challenge...
