BACKGROUND: Research shows that personnel working in mental health facilities may share some of the societal prejudices towards mental illness. This might result in stigmatizing behaviours towards people suffering from mental disorders, undermining the quality of their care. AIMS: To describe and compare attitudes towards mental illness across a sample of professionals working in a wide range of mental health facilities in Spain, Portugal and Italy. METHOD: We administered a survey to personnel including two questionnaires related to stigmatizing attitudes: The Community Attitudes toward the Mentally Ill (CAMI) and the Attribution Questionnaire (AQ-27)...

REVIEW
Rebecca L Kitchener, Amy M Grunden
Cyanobacteria are photosynthetic prokaryotes that can fix atmospheric CO2 and can be engineered to produce industrially important compounds such as alcohols, free fatty acids, alkanes used in next-generation biofuels, and commodity chemicals such as ethylene or farnesene. They can be easily genetically manipulated, have minimal nutrient requirements, and are quite tolerant to abiotic stress making them an appealing alternative to other biofuel-producing microbes which require additional carbon sources and plants which compete with food crops for arable land...

Parenting is linked to conduct disorders (CD) and substance related disorders (SRD) in adolescents, but with differences according to cultural context. A questionnaire with two versions (parenting questionnaire TXP-A for adolescents and TXP-C  for primary caregivers) was designed using the Delphi method to evaluate parenting practices related to CD and SRD in a Spanish population. It was validated in a community sample of 631 adolescents aged between 14 and 16 and their caregivers. Results suggest a 29-item TXP-A questionnaire with bifactorial structure: affection-communication and control-structure, with high internal (Cronbach’s alpha=0...

AIMS: Endothelial cells (ECs) constitute the defensive barrier of vasculature, which maintains the vascular homeostasis. Mitochondrial oxidative stress (mitoOS) in ECs significantly affects the initiation and progression of vascular diseases. The higher serum thyroid stimulating hormone (TSH) level is being recognized as a nonconventional risk factor responsible for the increased risk of cardiovascular diseases in subclinical hypothyroidism (SCH). However, effects and underlying mechanisms of elevated TSH on ECs are still ambiguous...

CCN family, a group of six extracellular matrix-associated proteins, plays an important role in fibrosis. WISP3 has addressed as a pro-fibrotic molecule in the development of human lung fibrosis. However, whether WISP3 involved in the activation and proliferation of renal fibroblast, and ultimately inhibited fibroblast-myofibroblast transdifferentiation remained unknown. Herein, we found that down-regulated WISP3 was involved in the fibrogenesis of rat renal NRK-49F cells induced by transforming growth (TGF-β1), which was further confirmed in a rat renal fibrosis induced by unilateral ureteral obstruction (UUO)...

Retention of fetal membranes (RFM) of cows is an important reproductive disturbance, and is related to miRNAs. Vascular endothelial growth factor (VEGF)A, regulated by miRNA-185, can activate arachidonic acid (ARA) release via the VEGFA signaling pathway, which influences RFM. The aim of this study was to explore the pathogenic mechanism of RFM by investigating the regulatory relationship between miRNA-185 and the VEGFA signaling pathway. Serum samples of healthy Holstein dairy cows (n = 20) and RFM cows (n = 12), with a similar age, parity, weight, and milk yield, were collected to detect VEGFA and ARA concentrations at 6, 12, and 24 h after calving...

The tumor microenvironment (TME) governs all aspects of cancer progression and in vitro 3D cell culture platforms are increasingly developed to emulate the interactions between components of the stromal tissues and cancer cells. However, conventional cell culture platforms are inadequate in recapitulating the TME, which has complex compositions and dynamically changing matrix mechanics. In this study, we developed a dynamic gelatin-hyaluronic acid hybrid hydrogel system through integrating modular thiol-norbornene photopolymerization and enzyme-triggered on-demand matrix stiffening...

OBJECTIVE: Although hospitals have been described as inadequate place for end-of-life care, many deaths still occur in hospital settings. Although patient-reported outcome measures have shown positive effects for patients in need of palliative care, little is known about how to implement them. We aimed to explore the feasibility of a pilot version of an implementation strategy for the Integrated Palliative care Outcome Scale (IPOS) in acute care settings. METHOD: A strategy, including information, training, and facilitation to support the use of IPOS, was developed and carried out at three acute care units...

Micropatterning is a promising technique for modulating culture environments. In this study, we investigated the effect of spheroid separation distance on their properties in a micropatterned chip of HepG2 spheroids. The basic chip design consisted of 37 collagen spots (300 μm in diameter) in a hexagonal arrangement on a glass substrate; the region without collagen-spots was modified by polyethylene glycol to create the non-adhesive surface. Three similar chips were fabricated with gap distances between collagen-spots of 500, 1000, and 1500 μm...

The use of mesenchymal stromal cell (MSC) therapy for the treatment of type 2 diabetes (T2D) and T2D complications is promising; however, the investigation of MSC function in the setting of T2D has not been thoroughly explored. In our current study, we investigated the phenotype and function of MSCs in a simulated in vitro T2D environment. We show that palmitate, but not glucose, exposure impairs MSC metabolic activity with moderate increases in apoptosis, while drastically affecting proliferation and morphology...

Poor insight in schizophrenia is prevalent across cultures and phases of illness. In this review, we examine the recent research on the relationship of insight with behavior, mood and perceived quality of life, on its complex roots, and on the effects of existing and emerging treatments. This research indicates that poor insight predicts poorer treatment adherence and therapeutic alliance, higher symptom severity and more impaired community function, while good insight predicts a higher frequency of depression and demoralization, especially when coupled with stigma and social disadvantage...

Melatonin is involved in the physiological regulation of the β- amyloid precursor protein (βAPP) cleaving secretases which are responsible for generation of the neurotoxic amyloid beta (Aβ) peptide, one of the hallmarks of Alzheimer's disease (AD) pathology. In this study, we aimed to determine the underlying mechanisms of this regulation under pathological conditions. We establish that melatonin prevents Aβ42 -induced down-regulation of a disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) as well as up-regulation of β-site APP-cleaving enzyme 1 (BACE1) and presenilin 1 (PS1) in SH-SY5Y cell cultures...

Human synovial mesenchymal stem cells (hSMSCs) are a promising cell source for cartilage regeneration because of their superior chondrogenic potential in vitro. This study aimed to further optimize the conditions for inducing chondrogenesis of hSMSCs, focusing on the dose of dexamethasone in combination with transforming growth factor-β3 (TGFβ3) and/or bone morphogenetic protein-2 (BMP2). When hSMSCs-derived aggregates were cultured with TGFβ3, dexamethasone up to 10 nM promoted chondrogenesis, but attenuated it with heterogeneous tissue formation when used at concentrations over than 100 nM...

The dissociated dorsal root ganglion (DRG) neurons with or without culture were widely used for investigation of their electrophysiological properties. The culture procedures, however, may alter the properties of these neurons and the effects are not clear. In the present study, we recorded the action potentials (AP) and the voltage-gated Na+, K+, and Ca2+ currents with patch clamp technique and measured the mRNA of Nav1.6-1.9 and Cav2.1-2.2 with real-time PCR technique from acutely dissociated and 1-day (1-d) cultured DRG neurons...

Microvesicles (MVs) released by cells are involved in a multitude of physiological events as important mediators of intercellular communication. MVs derived from mesenchymal stem cells (MSCs) contain various paracrine factors from the cells that primarily contribute to their therapeutic efficacy observed in numerous clinical trials. As nano-sized and bi-lipid layered vesicles retaining therapeutic potency equivalent to that of MSCs, MSC-derived MVs have been in focus as ideal medicinal candidates for regenerative medicine, and are preferred over MSC infusion therapy with their improved safety profiles...

Dermatophytes are the group of filamentous fungi infecting keratinized structures such as skin, hair, and nails. Knowledge about genes and molecular mechanisms responsible for pathogenicity, as well as other biological properties of Microsporum canis is still relatively poor. The qRT-PCR is a reliable technique for quantifying gene expression across various biological processes, and choosing a set of suitable reference genes to normalize the expression data is a crucial step of this technique. We investigated the suitability of nine candidate reference genes: β-act, β-tub, adp-rf, ef1-α, sdha, rpl2, mbp1, psm1, and rGTPa for gene expression analysis in the dermatophyte M...

We aimed at identifying potential clostridial factors linking these bacteria with necrotizing enterocolitis (NEC). We compared the phenotypic traits, stress responses, cellular cytotoxicity and inflammatory capabilities of the largest collection of Clostridium butyricum and Clostridium neonatale strains isolated from fecal samples of NEC and control preterm neonates (PN). When strains characteristics were used as explanatory variables, a statistical discriminant analysis allowed the separation of NEC and control strains into separate groups...

BACKGROUND: Men's involvement in maternal and child health presents an opportunity for the advancement of maternal and child nutrition as men often play a key role in decision-making particularly regarding women's reproductive health. While most research on men's involvement in maternal and child health has focused on men's participation in antenatal care, this study focuses specifically on men's involvement in maternal and child nutrition. The purpose of the study is to explore how men's involvement is conceptualised in rural Central Malawi, highlighting the key factors influencing men's involvement in maternal and child health...

DOCA-salt and obesity-related hypertension are associated with inflammation and sympathetic nervous system hyperactivity. Prejunctional α2-adrenergic receptors (α2ARs) provide negative feedback to norepinephrine release from sympathetic nerves through inhibition of N-type Ca2+ channels. Increased neuronal norepinephrine release in DOCA-salt and obesity-related hypertension occurs through impaired α2AR signaling, however, the mechanisms involved are unclear. Mesenteric arteries are resistance arteries that receive sympathetic innervation from the superior mesenteric and celiac ganglia (SMCG)...

The EGFR/ADAM17 signaling pathway mediates the shedding of growth factors and secretion of cytokines, and is involved in chronic inflammation and tissue remodeling. Since these are hallmarks of cystic fibrosis (CF) lung disease, we hypothesized that CFTR deficiency enhances EGFR/ADAM17 activity in human bronchial epithelial cells. In CFBE41o- cells lacking functional CFTR (iCFTR-) cultured at air-liquid interface (ALI) we found enhanced ADAM17-mediated shedding of the EGFR ligand amphiregulin (AREG) compared to genetically identical cells with induced CFTR expression (iCFTR+)...
