Recent studies suggest that evolutionary changes can occur on a contemporary time scale. Hence, evolution can influence ecology and vice-versa. To understand the importance of eco-evolutionary dynamics in population dynamics, we must quantify the relative contribution of ecological and evolutionary changes to population growth and other ecological processes. To date, however, most eco-evolutionary dynamics studies have not partitioned the relative contribution of plastic and evolutionary changes in traits on population, community and ecosystem processes...

Most of the European Union (EU) and European Economic Area (EEA) is considered a region of very low hepatitis A virus (HAV) endemicity; however, geographical differences exist. We did a systematic review with the aim of describing seroprevalence and susceptibility in the general population or special groups in the EU and EEA. We searched databases and public health national institutes websites for HAV seroprevalence records published between Jan 1, 1975, and June 30, 2014, with no language restrictions. An updated search was done on Aug 10, 2016...

Escherichia coli lacking the glucose phosphotransferase system (PTS), mannose PTS and glucokinase are supposedly unable to grow on glucose as the sole carbon source (Curtis SJ, Epstein W. J Bacteriol 1975;122:1189-1199). We report that W ptsG manZ glk (ALS1406) grows slowly on glucose in media containing glucose with a second carbon source: ALS1406 metabolizes glucose after that other carbon source, including arabinose, fructose, glycerol, succinate or xylose, is exhausted. Galactose is an exception to this rule, as ALS1406 simultaneously consumes both galactose and glucose...

PURPOSE: To analyze the clinical and radiographic characteristics, treatment, and outcome of patients with elbow osteoblastoma. PATIENTS AND METHODS: We present 13 patients (7 males and 6 females; mean age, 28 years) diagnosed and treated for an elbow osteoblastoma from 1975 to 2012. Mean follow-up was 29 months (range 12-60 months). Clinical presentation, imaging, surgical treatment, complications, range of elbow motion, and functional outcome were evaluated...

School psychologists who experience challenges delivering face-to-face consultation may utilize videoconferencing to facilitate their consultation activities. Videoconferencing has been found to be an effective method of service delivery in related fields and emerging research suggests that it may be effective for providing teacher training and support in school settings. In this exploratory investigation, we used the Consultation Analysis Record (Bergan & Tombari, 1975) and its four indices to assess the effectiveness of conducting problem identification interviews via videoconferencing versus face-to-face...

BACKGROUND: The important but complicated research questions regarding the optimization of mammography screening for the detection of breast cancer are unable to be answered through any single trial or a simple meta-analysis of related trials. The Cancer Intervention and Surveillance Network (CISNET) breast groups provide answers using complex statistical models to simulate population dynamics. Among them, the MD Anderson Cancer Center (Model M) takes a unique approach by not making any assumptions on the natural history of breast cancer, such as the distribution of the indolent time before detection, but simulating only the observable part of a woman's disease and life...

BACKGROUND: Almost 44% of our nation's 23 million men and women veterans are 65 years of age or older. Most are proud of their service, yet many believe their services for our country were forgotten, especially those in combat between 1950 and 1975. PURPOSE: Further information to ultimately assist their holistic well-being will be important for nursing practice as countless older veterans are beginning to obtain more care within civilian facilities. Using the Korean War (1950-1953) as a backdrop to illustrate the interconnectiveness of older veteran physical, emotional, and spiritual concerns that can occur from a military deployment, the major purposes of this article are to provide a brief historical snapshot of that war and discuss prior-era military environmental situations that now are producing the lingering effects from their combat exposure...

Migration of the catheter tip of a ventriculoperitoneal shunt (VPS) through a patent processus vaginalis (PV) has seldom being reported. In this series, we analyzed all cases of inguinoscrotal migration of an VPS catheter at our center. Between 1975 and 2015, 295 VPS insertions were performed. In seven infants (2.3%), migration of the catheter through a patent PV was demonstrated. Cases with hydroceles had associated VPS malfunction, but cases with hernias were not associated with it. The current recommendation is to delay a PV closure until 2 years of age in cases of infants with hydrocele without further radiological examinations, but this might not be the case in infants with VPS...

BACKGROUND: Hand osteoarthritis is a common condition characterised by joint pain and muscle weakness. These factors are thought to contribute to ongoing disability. Some evidence exists that resistance training decreases pain, improves muscle strength, and enhances function in people with knee and hip osteoarthritis. However, there is currently a lack of consensus regarding its effectiveness in people with hand osteoarthritis. Therefore, the aim of this systematic review and meta-analysis was to establish whether resistance training in people with hand osteoarthritis increases grip strength, decreases joint pain, and improves hand function...

The araneid genus Larinia Simon currently includes 56 species, eleven of them with New World distribution (World Spider Catalog, 2016). North American species of the genus were revised first time by Levi (1975) and South American species by Harrod et al. (1991). According to these authors there are four species known from subtropical South America (Larinia bivittata Keyserling 1885; L. montecarlo (Levi, 1988); L. t-notata (Tullgren, 1905); L. tucuman Harrod, Levi & Leibensperger, 1991) and also four species known from tropical South America (L...

REVIEW
Clare L Abram, Clifford A Lowell
The motheaten mouse was first described in 1975 as a model of systemic inflammation and autoimmunity, as a result of immune system dysregulation. The phenotype was later ascribed to mutations in the cytoplasmic tyrosine phosphatase Shp1. This phosphatase is expressed widely throughout the hematopoietic system and has been shown to impact a multitude of cell signaling pathways. The determination of which cell types contribute to the different aspects of the phenotype caused by global Shp1 loss or mutation and which pathways within these cell types are regulated by Shp1 is important to further our understanding of immune system regulation...

Since the economic reform, China has actively participated in the global market with rapid industrialization and gradually dominated the utilization and consumption of some critical materials, one of which is copper. China has reigned the global anthropogenic cycle of copper since 2004. We explore copper flows along with the international trade of China during 1975-2015, through life cycle lens, from ore to final products. Our main finding is that China has become more active in the copper-related trade, indicated by its great increase in trade volume and the number of trade partners...

OBJECTIVE: Primary retroperitoneal mucinous tumors (PRMTs) are rare epithelial neoplasms arising in the retroperitoneal space whose pathogenesis is poorly understood. To date, only single-case reports and small case series on diagnosis and management of these tumors exist. The aim of this first-time meta-analysis was to provide more reliable data to inform the management of PRMTs. METHODS: Database searches were conducted to identify case reports and case series between the years of 1975 and 2015...

The first description of ultrasound to estimate fetal weight was published in 1975.(1) More than 40 years later, we still do not know whether universal use of this method prevents perinatal deaths. Multiple lines of evidence suggest that it should work: (i) stillbirth is strongly associated with fetal growth restriction (FGR),(2) (ii) current methods using targeted ultrasound have low detection rates for FGR,(3) (iii) there is strong evidence that induction of labour at term reduces perinatal mortality.

Forty-two years ago, Capra published "The Tao of Physics" (Capra, 1975). In this book (page 17) he writes: "The exploration of the atomic and subatomic world in the twentieth century has …. necessitated a radical revision of many of our basic concepts" and that, unlike 'classical' physics, the sub-atomic and quantum "modern physics" shows resonances with Eastern thoughts and "leads us to a view of the world which is very similar to the views held by mystics of all ages and traditions." This article stresses an analogous situation in biology with respect to a new theoretical approach for studying living systems, Integral Biomathics (IB), which also exhibits some resonances with Eastern thought...

Intense demand for water in the Central Valley of California and related increases in groundwater nitrate concentration threaten the sustainability of the groundwater resource. To assess contamination risk in the region, we developed a hybrid, non-linear, machine learning model within a statistical learning framework to predict nitrate contamination of groundwater to depths of approximately 500m below ground surface. A database of 145 predictor variables representing well characteristics, historical and current field and landscape-scale nitrogen mass balances, historical and current land use, oxidation/reduction conditions, groundwater flow, climate, soil characteristics, depth to groundwater, and groundwater age were assigned to over 6000 private supply and public supply wells measured previously for nitrate and located throughout the study area...

Background Advances in neonatal care have reduced mortality but increased morbidity in babies born pre-maturely or after high-risk pregnancies. However, this often increases the burden on the family and the parents in particular. A systematic review of the literature was conducted that demonstrated the importance of psychosocial support for parents of children in neonatal care. Methods A systematic search of Pubmed, Psyndex, CINAHI and medpilot was conducted. Reference lists of the included articles were also searched for relevant publications...
