The multimillion-euro fertility industry increasingly tailors its treatments to infertile people who are willing to travel across national borders for treatments inaccessible at home, especially reproductive tissue donor treatments. Finland is the Nordic destination for access to donor eggs, particularly for Swedes and Norwegians hoping for a donor match that will achieve a child of phenotypically plausible biological descent. Finns are seen as Nordic kin, and the inheritability of "Nordicness" is reinforced at clinics...

Growth impairment is a major public health issue for children in Tanzania. The question remains as to whether dietary mycotoxins play a role in compromising children's growth. We examined children's exposures to dietary aflatoxin and fumonisin and potential impacts on growth in 114 children under 36 months of age in Haydom, Tanzania. Plasma samples collected from the children at 24 months of age (N = 60) were analyzed for aflatoxin B1 -lysine (AFB1 -lys) adducts, and urine samples collected between 24 and 36 months of age (N = 94) were analyzed for urinary fumonisin B1 (UFB1 )...

We articulate the lifespan theory of change by which an attachment-focused integrative reminiscence intervention, "Life Writing", is expected to interrupt the continuing problem of insecure attachment in adults and reverse associated reduced health and well-being outcomes. Based on preliminary studies and previous research, Life Writing is expected to foster earned-secure attachment in adults who work through subjective memories of unresolved attachment trauma. Roughly two decades of research on integrative reminiscence interventions like Life Writing show their consistent and wide-ranging positive impact...

Distraction osteogenesis is an effective method for generating large amounts of bone in situ for treating pathologies such as large bone defects or skeletal malformations, for instance leg-length discrepancies. While an optimized distraction procedure might have the potential to reduce the rate of complications significantly, our knowledge of the underlying mechanobiological processes is still insufficient for systematic optimization of treatment parameters such as distraction rate or fixation stiffness. We present a novel numerical model of lateral distraction osteogenesis, based on a mechanically well-controlled in vivo experiment...

Interactions between DNA and proteins located in the cell nucleus play an important role in controlling physiological processes by specifying, augmenting and regulating context-specific transcription events. Chromatin immunoprecipitation (ChIP) is a widely used methodology to study DNA-protein interactions and has been successfully used in various cell types for over three decades. More recently, by combining ChIP with genomic screening technologies and Next Generation Sequencing (e.g. ChIP-seq), it has become possible to profile DNA-protein interactions (including covalent histone modifications) across entire genomes...

INTRODUCTION: The paced serial addition test (PSAT) is regularly used to assess cognitive deficits in various neuropsychiatric conditions. Being a complex test, it reflects the status of multiple cognitive domains such as working memory, information processing speed and executive functioning. Two versions of the PSAT exist. One uses auditory stimuli through spoken numbers and is known as the PASAT, while the other one presents patients with visual stimuli and is called PVSAT. The PASAT is considered more frustrating by patients, and hence the visual version is usually preferred...

OBJECTIVES: To determine if a discrepancy exists between subjective symptoms and the grade of endoscopic gastroesophageal reflux disease (GERD) in diabetes mellitus (DM) patients. METHODS: All 2,884 patients who underwent esophagogastroduodenoscopy completed the modified Gastrointestinal Symptom Rating Scale (GSRS), an interview-based rating scale consisting of 16 items including a question on acid regurgitation. Patients were divided into DM and non-DM groups (1,135 and 1,749 patients, respectively)...

Understanding the relationship between external stimuli and the spiking activity of cortical populations is a central problem in neuroscience. Dense recurrent connectivity in local cortical circuits can lead to counterintuitive response properties, raising the question of whether there are simple arithmetical rules for relating circuits' connectivity structure to their response properties. One such arithmetic is provided by the mean field theory of balanced networks, which is derived in a limit where excitatory and inhibitory synaptic currents precisely balance on average...

We present a new educational initiative called Meet-U that aims to train students for collaborative work in computational biology and to bridge the gap between education and research. Meet-U mimics the setup of collaborative research projects and takes advantage of the most popular tools for collaborative work and of cloud computing. Students are grouped in teams of 4-5 people and have to realize a project from A to Z that answers a challenging question in biology. Meet-U promotes "coopetition," as the students collaborate within and across the teams and are also in competition with each other to develop the best final product...

Hop ( Humulus lupulus L.), as a key ingredient for beer brewing, is also a source of many biologically active molecules. A notable compound, 8-prenylnaringenin (8-PN), structurally belonging to the group of prenylated flavonoids, was shown to be a potent phytoestrogen, and thus, became the topic of active research. Here, we overview the pharmacological properties of 8-PN and its therapeutic opportunities. Due to its estrogenic effects, administration of 8-PN represents a novel therapeutic approach to the treatment of menopausal and post-menopausal symptoms that occur as a consequence of a progressive decline in hormone levels in women...

BACKGROUND: Pain-coping strategies and appraisals are responses to the pain experience. They can influence patient-reported and physical performance outcome measures in a variety of disorders, but the associations between a comprehensive profile of pain-coping responses and preoperative pain/function and physical performance measures in patients scheduled for knee arthroplasty have not been examined. Patients with moderate to high pain catastrophizing (a pain appraisal approach associated with an exaggerated focus on the threat value of pain) may represent an excellent study population in which to address this knowledge gap...

Two cryptic species of haploporid digeneans belonging in Saccocoelioides are described from Costa Rica; one from a poeciliid fish Poecilia gillii and the other from a characid fish, Astyanx aeneus. Traditional morphological features are examined and found to be largely inefficient for differentiate among new species and 20 New World congeners. Comparison of ribosomal DNA sequences among the 2 new species, 2 North American, 4 Middle American, and 3 South American species of Saccocoelioides, including the type-species Saccocoelioides nanii from Argentina and Saccocoelioides sogandaresi from Texas, is effective for differentiating among these species...

AIM: To better understand the hepatocellular carcinoma (HCC) patient journey, we conducted a patient survey across 13 countries. METHODS: The survey included closed- and open-ended questions developed using an iterative process to gather information on demographics, diagnosis and treatment. Patients self-selected or were directed to the online survey by their doctor. RESULTS: A total of 256 patients completed the survey. More than two-thirds (68%) felt they did not receive enough information about HCC at diagnosis...

BACKGROUND: The long-term outcome after the treatment of subacromial impingement syndrome (SAIS) with either nonsurgical or surgical methods has not been thoroughly investigated. Hypothesis/Purpose: The purpose was to evaluate the long-term clinical outcome and the presence of rotator cuff injuries and osteoarthritis (OA) after the surgical and nonsurgical treatment of SAIS. The hypothesis was that, at a minimum 10 years after the initial treatment, patients who had undergone acromioplasty would have a better clinical outcome and run a lower risk of developing rotator cuff ruptures and OA as compared with those treated with physical therapy...

The sensory neurotransmitter calcitonin gene-related peptide (CGRP) is associated with vasodilation of systemic arteries through activation of ATP-sensitive potassium channels (KATP) in smooth muscle cells (SMCs), however its effects on endothelial cell (EC) membrane potential (Vm) are unresolved. In pulmonary arteries (PAs) of C57BL/6J mice, we questioned whether CGRP would hyperpolarize ECs as well as SMCs. Intact PAs were isolated and immunostained for CGRP to confirm sensory innervation; vessel segments (length, 1-2 mm; diameter ∼150 µm) with intact or denuded endothelium were cannulated and pressurized to 16 cm H2O at 37{degree sign}C...

ISSUE ADDRESSED: Currently, two food sufficiency questions are utilised as a proxy measure of national food security status in Australia. These questions do not capture all dimensions of food security and have been attributed with underreporting of the problem. The purpose of this study was to investigate food security using the short form of the US Household Food Security Survey Module (HFSSM) within an Australian context; and explore the relationship between food security status and multiple socio-demographic variables...
