MicroRNA signatures of BAL cells and alveolar macrophages are currently lacking in IPF. Here we sought to investigate the expression of fibrosis-related microRNAs in the cellular component of the BAL in IPF. We thus focused on microRNAs previously associated with fibrosis (miR-29a, miR-29b, miR-29c, let-7d, and miR-21) and rapid IPF progression (miR-185, miR-210, miR-302c-3p miR-376c and miR-423-5p). Among the tested microRNAs miR-29a and miR-185 were found significantly downregulated in IPF while miR-302c-3p and miR-376c were not expressed by BAL cells...

Purpose: To determine whether structural protein composition and expression of key regulatory genes are altered in strabismic human extraocular muscles. Methods: Samples from strabismic horizontal extraocular muscles were obtained during strabismus surgery and compared with normal muscles from organ donors. We used proteomics, standard and customized PCR arrays, and microarrays to identify changes in major structural proteins and changes in gene expression. We focused on muscle and connective tissue and its control by enzymes, growth factors, and cytokines...

Microsphere-assisted microscopy has received a lot of attention recently due to its simplicity and its capability to surpass the diffraction limit. However, to date, sub-diffraction-limit features have only been observed in virtual images formed through the microspheres. We show that it is possible to form real, super-resolution images using high-refractive index microspheres. Also, we report on how changes to a microsphere's refractive index and size affect image formation and planes. The relationship between the focus position and the additional magnification factor is also investigated using experimental and theoretical methods...

Neurulation, the early embryonic process of forming the presumptive brain and spinal cord, is highly complex and involves hundreds of genes in multiple genetic pathways. Mice have long served as a genetic model for studying human neurulation, and the resulting neural tube defects (NTDs) that arise when neurulation is disrupted. Because mice appear to show mostly single gene inheritance for NTDs and humans show multifactorial inheritance, mice sometimes have been characterized as a simpler model for the identification and study of NTD genes...

INTRODUCTION: The antenatal diagnosis of open spina bifida (OSB), a neural tube defect, is predominantly made at the second trimester morphology scan by ultrasound detection of structural abnormalities resulting from the associated Chiari II malformation. Evidence has emerged suggesting that these structural abnormalities can be detected earlier, by examination of the posterior fossa as part of the first trimester nuchal translucency scan. In particular, absence of the intra-cranial translucency (IT) of the fourth ventricle has shown promise as a diagnostic marker of OSB, although the sensitivity and specificity of this finding varies widely in the literature...

MicroRNAs (miRNAs) are an important class of small, non-coding RNAs that control target genes expression by degradation of target mRNAs or by inhibiting protein translation in many biological processes and cellular pathways. In a previous study, we found that miR-29b interfered with bovine viral diarrhea virus (BVDV) replication. However, the mechanisms of regulation of miR-29b expression are not well known. DNA methylation is an important epigenetic mechanism for silencing gene transcription, and plays an important role in promoter choice, protein expression, and regulation of miRNAs expression...

: In the last decade the interest in autophagy got an incredible boost and the phenomenon quickly turned into an extensive research field. Interestingly, dysfunction of this cytoplasmic clearance system has been proposed to lie at the root of multiple diseases including cancer. We therefore consider it crucial from a toxicological point of view to investigate if nanomaterials that are developed for biomedical applications interfere with this cellular process. Here, we study the highly promising 'gradient alloyed' quantum dots (QDs) that differ from conventional ones by their gradient core composition which allows for better fluorescent properties...

BACKGROUND: Side effects, or the adverse effects of drugs, contain important clinical phenotypic information that may be useful in predicting novel or unknown targets of a drug. It has been suggested that drugs with similar side-effect profiles may share common targets. The diagnostic class, Major Depressive Disorder, is increasingly viewed as being comprised of multiple depression subtypes with different biological root causes. One 'type' of depression generating substantial interest today focuses on patients with high levels of inflammatory burden, indicated by elevated levels of C-reactive proteins (CRP) and pro-inflammatory cytokines such as interleukin 6 (IL-6)...

BACKGROUND: Gestational weight gain (GWG) is an important predictor of short and long-term pregnancy outcomes for both mother and child, and women who set a GWG goal are more likely to gain within recommended ranges. Little information is available regarding potentially modifiable factors that underlie a woman's GWG goals. Our aims were to explore women's perceptions regarding factors that affect GWG, their understanding of appropriate GWG, their goal-setting experiences including patient-health care provider (HCP) conversations, and supportive interventions they would most like to help them achieve the recommended GWG...

OBJECTIVE: Australian Indigenous children experience some of the most substantial health inequalities globally. In this context, research regarding their health and well-being has overemphasised physical illnesses with limited exploration of a diverse range of dimensions and determinants, particularly those based on Indigenous holistic understandings of health and well-being. This deficit-based approach has thus missed many strengths and assets of Indigenous children. This research aimed to gain insight into the perspectives of Indigenous children about their health and well-being in an urban setting in Australia...

The quality of clinical ethics services in health care organizations is increasingly seen as an important aspect of the overall quality of care. But measuring this quality is difficult because there is a lack of clarity and consensus regarding the objectives of clinical ethics and the best outcome domains to measure. The aim of this qualitative study is to explore the views of experts about the objectives and outcomes of clinical ethics services in the US. We interviewed 19 experts in clinical ethics, focusing on the appropriate objectives and outcomes of a clinical ethics service (CES)...

This article examines the transfer of technology from Finnish enterprises to Soviet industry during the USSR's period of technological modernization between 1955 and 1964. It centers on the forestry sector, which was a particular focus of modernization programs and a key area for the transfer of foreign techniques and expertise. The aim of the article is to investigate the role of trips made by Soviet specialists to foreign (primarily Finnish) enterprises in order to illustrate the nontechnological influences that occurred during the transfer of technologies across the cold war border...

An MDHAQ/RAPID3 (multidimensional health assessment questionnaire/routine assessment of patient index data) was developed from the HAQ over 25 years, based on observations made from completion by every patient (with all diagnoses) at every routine rheumatology visit since 1980. Modification of the HAQ was viewed as similar to improving a laboratory test, with a primary focus on clinical value for diagnosis, prognosis, and/or management, as well as feasibility for minimal effect on clinical workflow. Rigorous attention, was also directed to validity, reliability, other methodologic and technological considerations, but after clinical value and feasibility were established...

New-born screening programs for congenital disorders and chronic disease are expanding worldwide and children "at risk" are identified by nationwide tracking systems at the earliest possible stage. These practices are never neutral and raise important social and ethical questions. An emergent concern is that a reflexive professionalism should interrogate the ever earlier interference in children's lives. The Flemish community of Belgium was among the first to generalize the screening for hearing loss in young children and is an interesting case to study the public justification of early interventions for families with deaf children...

Why do individuals mentally modify reality (e.g., "If it hadn't rained, we would have won the game")? According to the dominant view, counterfactuals primarily serve to prepare future performance. In fact, individuals who have just failed a task tend to modify the uncontrollable features of their attempt (e.g., "If the rules of the game were different, I would have won it"), generating counterfactuals that are unlikely to play any preparatory role. By contrast, they generate prefactuals that focus on the controllable features of their ensuing behavior (e...

BACKGROUND: The incidence of post-endoscopic sphincterotomy (ES) bleeding is reportedly 2.0-5.0 %. Among various hemostatic methods, endoclip therapy is an effective modality in gastrointestinal bleeding. However, endoclip application for post-ES hemorrhage has not been widely studied, partly because of the difficulty in placing of clips using a duodenoscope. A cap-fitted forward-viewing gastroscope can easily visualize the major papilla and overcome the technical difficulty in applying endoclips...
