Microparticles (MPs) are submicronic vesicles which are formed by budding of the cellular membrane of virtually any cell type in response to cell activation or apoptosis. Both circulating MPs and MPs generated within tissues harbor molecules with a large repertoire of biological activities and transfer material to target cells. Depending on their cellular origin, the stimuli triggering their formation, or their localization, they may participate in the maintenance of organ or vascular homeostasis as well as inducing dysfunction...

Alexandar Tzankov, Luigi Tornillo
Accreditation is a procedure by which an authoritative body gives formal recognition that an organization is competent to carry out specific tasks according to certain standards. Accreditation of pathology laboratories according to ISO 15189 is now becoming more and more a matter of course in continental Europe. This review describes some practical experience aspects with our own pathology laboratory accreditation according to ISO 15189, and outlines the advantages, addresses critical points, and discusses certain caveats of this process...

REVIEW
Ming Pei
Adult stem cells are a promising cell source for cartilage regeneration. Unfortunately, due to donor age and ex vivo expansion, stem cell senescence becomes a huge hurdle for these cells to be used clinically. Increasing evidence indicates that environmental preconditioning is a powerful approach in promoting stem cells' ability to resist a harsh environment post-engraftment, such as hypoxia and inflammation. However, few reports organize and evaluate the literature regarding the rejuvenation effect of environmental preconditioning on stem cell proliferation and chondrogenic differentiation capacity, which are important variables for stem cell based tissue regeneration...

Patients with acquired and inherited bone marrow failure syndromes (BMFS) have ineffective hematopoiesis due to impairments of the hematopoietic stem cell compartment. Common manifestations of BMFS include varying degrees of peripheral blood cytopenias and, sometimes, progression to acute myelogenous leukemia. Research efforts have been made all over the world to improve understanding of the pathogenesis of these diseases and their clinical implications. The Aplastic Anemia and MDS International Foundation (AAMDSIF) is an independent nonprofit organization whose mission is to help patients and family members cope with BMFS...

The protein kinases (PKs), belonging to serine/threonine kinase (STKs), are important drug targets for a wide spectrum of diseases in human. Among protein kinases, the Casein Kinases (CKs) are vastly expanded in various organisms, where, the malarial parasite Plasmodium falciparum possesses a single member i.e., PfCKI, which can phosphorylate various proteins in parasite extracts in vitro condition. But, the structure-function relationship of PfCKI and dynamics of ATP binding is yet to be understood. Henceforth, an attempt was made to study the dynamics, stability, and ATP binding mechanisms of PfCKI through computational modelling, docking, molecular dynamics (MD) simulations, and MM/PBSA binding free energy estimation...

It has been hypothesized that cysteine cathepsins (CTs) along with matrix metalloproteases (MMPs) may work in conjunction in the proteolysis of mature dentin matrix. The aim of this study was to verify simultaneously the distribution and presence of cathepsins B (CT-B) and K (CT-K) in partially demineralized dentin; and further to evaluate the activity of CTs and MMPs in the same tissue. The distribution of CT-B and CT-K in sound human dentin was assessed by immunohistochemistry. A double-immunolabeling technique was used to identify, at once, the occurrence of those enzymes in dentin...

Tissue morphogenesis requires force-generating mechanisms to organize cells into complex structures. Although many such mechanisms have been characterized, we know little about how forces are integrated across developing tissues. We provide evidence that integrin-mediated cell-extracellular matrix (ECM) adhesion modulates the transmission of apically generated tension during dorsal closure (DC) in Drosophila. Integrin-containing adhesive structures resembling focal adhesions were identified on the basal surface of the amnioserosa (AS), an extraembryonic epithelium essential for DC...

BACKGROUND: Strong opioids are a cornerstone of pain treatment, of which morphine is considered an essential analgesic by the World Health Organization. Access to opioids is limited, due to restrictive laws, limited education, and high prices. This is the second phase of a global project to monitor and report the dispensing price of opioids with the specific aim to expand and increase the information and allow further analysis of the challenges in their availability and affordability...

Renaud Bastien, Yasmine Meroz
Nutation is an oscillatory movement that plants display during their development. Despite its ubiquity among plants movements, the relation between the observed movement and the underlying biological mechanisms remains unclear. Here we show that the kinematics of the full organ in 3D give a simple picture of plant nutation, where the orientation of the curvature along the main axis of the organ aligns with the direction of maximal differential growth. Within this framework we reexamine the validity of widely used experimental measurements of the apical tip as markers of growth dynamics...

A major aim of evolutionary biology is to explain the respective roles of adaptive versus non-adaptive changes in the evolution of complexity. While selection is certainly responsible for the spread and maintenance of complex phenotypes, this does not automatically imply that strong selection enhances the chance for the emergence of novel traits, that is, the origination of complexity. Population size is one parameter that alters the relative importance of adaptive and non-adaptive processes: as population size decreases, selection weakens and genetic drift grows in importance...

Together with recent advances in the processing and culture of human tissue, bioengineering, xenotransplantation and genome editing, Induced pluripotent stem cells (iPSCs) present a range of new opportunities for the study of human cancer. Here we discuss the main advantages and limitations of iPSC modeling, and how the method intersects with other patient-derived models of cancer, such as organoids, organs-on-chips and patient-derived xenografts (PDXs). We highlight the opportunities that iPSC models can provide beyond those offered by existing systems and animal models and present current challenges and crucial areas for future improvements toward wider adoption of this technology...

PURPOSE OF REVIEW: Meta-analysis provides the highest level of evidence-based efficacy of a medical treatment or intervention. Allergen immunotherapy in its two forms of subcutaneous immunotherapy and sublingual immunotherapy (SLIT) is an effective treatment of respiratory allergy as shown by meta-analyses, but in recent years there has been an overflow of meta-analyses on SLIT, with contrasting results that may generate confusion among physicians. RECENT FINDINGS: It can be observed that flaws are often present in meta-analyses including: incorrect selection of trials, inappropriate use of evaluation parameters for the analysis, and unsuitable analyses...

Addie Cunniff, Diane Spatz
The American Academy of Pediatrics and the World Health Organization recommend that infants receive human milk exclusively for the first 6 months of life and that breastfeeding continue beyond the first or second year of life for as long as a family deems appropriate. More infants in the United States and around the world are meeting this recommendation. As more infants breastfeed beyond the first year of life, best practices for weaning toddlers come into question. Little is known about concerns and practices of breastfeeding mothers weaning their children from feedings...

PURPOSE OF REVIEW: Whole lung tissue engineering is a relatively new area of investigation. In a short time, however, the field has advanced quickly beyond proof of concept studies in rodents and now stands on the cusp of wide-spread scale up to large animal studies. Therefore, this technology is ever closer to being directly clinically relevant. RECENT FINDINGS: The main themes in the literature include refinement of the fundamental components of whole lung engineering and increasing effort to direct induced pluripotent stem cells and lung progenitor cells toward use in lung regeneration...
