Focal adhesion displacement magnitude is a unifying feature of tensional homeostasis.

Acta Biomater 2020 Jul 4. Epub 2020 Jul 4.

Department of Biomedical Engineering, Boston University, 44 Cummington Mall, Boston, Massachusetts, 02215. Electronic address:

Tensional homeostasis is widely recognized to exist at the length scales of organs and tissues, but the cellular length scale mechanism for tension regulation is not known. In this study, we explored whether tensional homeostasis emerges from the behavior of the individual focal adhesion (FA), which is the subcellular structure that transmits cell stress to the surrounding extracellular matrix. Past studies have suggested that cell contractility builds up until a certain displacement is achieved, and we thus hypothesized that tensional homeostasis may require a threshold level of substrate displacement.

Upregulation of miR-133a by adiponectin inhibits pyroptosis pathway and rescues acute aortic dissection.

Acta Biochim Biophys Sin (Shanghai) 2020 Jul 7. Epub 2020 Jul 7.

Department of Emergency Medicine, Affiliated Hospital of Zunyi Medical University, Zunyi 563000, China.

Acute aortic dissection (AAD) is a cardiovascular emergency caused by the formation of hematoma in the middle layer of the aortic wall. Adiponectin (APN) is an adipose tissue-specific protein that has anti-inflammation and anti-atherosclerosis functions. Pyroptosis, as an inflammatory cell death, depends on the activation of caspase1, while nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) is a typical representative of the pyroptosis pathway.

Disturbed balance in the expression of MMP9 and TIMP3 in cerebral amyloid angiopathy-related intracerebral haemorrhage.

Acta Neuropathol Commun 2020 Jul 6;8(1):99. Epub 2020 Jul 6.

Department of Laboratory Medicine, Radboud University Medical Center, Nijmegen, The Netherlands.

Cerebral amyloid angiopathy (CAA) is characterized by the deposition of the amyloid β (Aβ) protein in the cerebral vasculature and poses a major risk factor for the development of intracerebral haemorrhages (ICH). However, only a minority of patients with CAA develops ICH (CAA-ICH), and to date it is unclear which mechanisms determine why some patients with CAA are more susceptible to haemorrhage than others. We hypothesized that an imbalance between matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) contributes to vessel wall weakening. Read More

Self-directed learning (SDL) is a rapidly developing trend in schools, although its prerequisites, such as children's skills and abilities to plan and monitor their own learning, have not been investigated in detail. Due to additional cognitive load it induces, SDL has been in some cases found to be detrimental for learning, especially for students with a lower cognitive capacity. With this study, we explored some of the causes for the variability in learning gains. Read More

Improvement of organisms by biomimetic mineralization: a material incorporation strategy for biological modification.

Acta Biomater 2020 Jul 3. Epub 2020 Jul 3.

Center for Biomaterials and Biopathways, Department of Chemistry, Zhejiang University, Hangzhou, 310027 China; Qiushi Academy for Advanced Studies, Zhejiang University, Hangzhou, 310027 China. Electronic address:

Biomineralization, a bio-organism controlled mineral formation process, plays an important role in linking biological organisms and mineral materials in nature. Inspired by biomineralization, biomimetic mineralization is used as a bridge tool to integrate biological organisms and functional materials together, which can be beneficial for the development of diversified functional organism-material hybrids. In this review, recent progresses on the techniques of biomimetic mineralization for organism-material combinations are summarized and discussed. Read More

Engineering the Cellular Mechanical Microenvironment to Regulate Stem Cell Chondrogenesis: Insights from a Microgel Model.

Acta Biomater 2020 Jul 3. Epub 2020 Jul 3.

Department of Biomedical Engineering, School of Materials Science and Engineering, South China University of Technology, Guangzhou, 510006, China; National Engineering Research Center for Tissue Restoration and Reconstruction (NERC-TRR), Guangzhou, 510006, China; Key Laboratory of Biomedical Materials and Engineering of the Ministry of Education, South China University of Technology, Guangzhou 510006, P. R. China; Guangdong Province Key Laboratory of Biomedical Engineering, South China University of Technology, Guangzhou, 510641, China. Electronic address:

Biophysical cues (especially mechanical cues) embedded in cellular microenvironments show a critical impact on stem cell fate. Despite the capability of traditional hydrogels to mimic the feature of extracellular matrix (ECM) and tune their physicochemical properties via diverse approaches, their relatively large size not only induces biased results, but also hinders high-throughput screening and analysis. In this paper, a microgel model is proposed to recapitulate the role of 3D mechanical microenvironment on stem cell behaviors especially chondrogenesis in vitro. Read More

Altered expressions and splicing profiles of Acin1 transcripts differentially modulate brown adipogenesis through an alternative splicing mechanism.

Biochim Biophys Acta Gene Regul Mech 2020 Jul 3:194601. Epub 2020 Jul 3.

School of Medical Laboratory Science and Biotechnology, College of Medical Science and Technology, Taipei Medical University, Taipei, Taiwan; PhD Program in Medical Biotechnology, College of Medical Science and Technology, Taipei Medical University, Taipei, Taiwan; Pulmonary Research Center, Wan Fang Hospital, Taipei Medical University, Taipei, Taiwan. Electronic address:

Apoptotic chromatin condensation inducer in the nucleus (also referred as Acin1) was first characterized as an RNA-binding protein involved in apoptosis. In later reports, Acin1 was identified as an auxiliary component of the exon junction complex (EJC) which is assembled throughout pre-messenger RNA splicing. In this study, results of whole-transcriptome analyses revealed reduced expressions and reprogrammed splicing profiles of Acin1 transcripts throughout development of brown adipose tissues (BATs) that execute non-shivering thermogenesis in small rodents and infants by consuming lipids.

Identification of human glycerophosphodiesterase 3 as an ecto phospholipase C that converts the G protein-coupled receptor 55 agonist lysophosphatidylinositol to bioactive monoacylglycerols in cultured mammalian cells.

A family of glycerol-based lysolipid mediators comprises lysophosphatidic acid as a representative phospholipidic member but also a monoacylglycerol as a non-phosphorus-containing member. These critical lysolipid mediators are known to be produced from different lysophospholipids by actions of lysophospholipases C and D in mammals. Some members of the glycerophosphodiesterase (GDE) family have attracted recent attention due to their phospholipid-metabolizing activity. Read More

Electronic address:

Miltefosine (hexadecylphosphocholine or HePC) is an alkylphosphocholine approved for the treatment of visceral and cutaneous Leishmaniasis. HePC exerts its effect by interacting with lipid membranes and affecting membrane-dependent processes. The molecular geometry of HePC suggests that the pharmacological function of HePC is to alter membrane curvature. Read More

Setting realistic goals for feeding infants when their mothers have suspected or confirmed COVID-19.

Acta Paediatr 2020 Jul 6. Epub 2020 Jul 6.

Department of Pediatrics (Neonatal Division), McMaster University, Hamilton, Ontario, Canada.

The pandemic is a stressful time for everyone, including mothers and healthcare providers who are concerned about the best and safest way to feed babies born to mothers with suspected or confirmed COVID-19. There is lack of consensus regarding mother-infant contact, unless the mother definitely has COVID-19 and even then there is a distinct lack of data to devise protocols for everyday clinical practice..

Involvement of clinical characteristics and HLA-DQ2 genotypes in paediatric patients with coeliac disease suffering from allergies.

Acta Paediatr 2020 Jul 6. Epub 2020 Jul 6.

Immunology Section, Ciudad Real University General Hospital, Ciudad Real, Spain.

The first description on the association of coeliac disease (CD) with allergic conditions dates in the 1970s, when was found the co-occurrence of asthma, eczema and rhinitis in adult patients with CD. Later, this likely connection was screened both in paediatric and adult populations, although with conflicting results (1,2). Hence, the relationship between CD and allergy is scarcely known.
