Authors:
D Gareth Jones

Anat Sci Educ 2018 Dec 15. Epub 2018 Dec 15.

Department of Anatomy, University of Otago, Dunedin, New Zealand.

New technological developments have frequently had major consequences for anatomy education, and have raised ethical queries for anatomy educators. The advent of three-dimensional (3D) printing of human material is showing considerable promise as an educational tool that fits alongside cadaveric dissection, plastination, computer simulation, and anatomical models and images. At first glance its ethical implications appear minimal, and yet the more extensive ethical implications around clinical bioprinting suggest that a cautious approach to 3D printing in the dissecting room is in order.

Biochim Biophys Acta Gen Subj 2018 Dec 13. Epub 2018 Dec 13.

Laboratory of Anatomy, School of Veterinary Medicine, Rakuno Gakuen University, Ebetsu, Hokkaido, Japan. Electronic address:

Musculocontractural Ehlers-Danlos syndrome (mcEDS) due to CHST14/D4ST1 deficiency (mcEDS-CHST14) is a recently delineated type of EDS caused by biallelic loss-of-function mutations in CHST14, which results in the depletion of dermatan sulfate (DS). Clinical characteristics of mcEDS-CHST14 consist of multiple malformations and progressive fragility-related manifestations, including skin hyperextensibility and fragility. Skin fragility is suspected to result from the impaired assembly of collagen fibrils caused by alteration of the glycosaminoglycan (GAG) chain of decorin-proteoglycan (PG) from DS to chondroitin sulfate (CS).

Immune cells in the retina and choroid: Two different tissue environments that require different defenses and surveillance.

Prog Retin Eye Res 2018 Dec 12. Epub 2018 Dec 12.

Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University, Clayton, Victoria, Australia.

In the eye immune defenses must take place in a plethora of differing microenvironments ranging from the corneal and conjunctival epithelia facing the external environment to the pigmented connective tissue of the uveal tract containing smooth muscle, blood vessels and peripheral nerves to the innermost and highly protected neural retina. The extravascular environment of the neural retina, like the brain parenchyma, is stringently controlled to maintain conditions required for neural transmission. The unique physiological nature of the neural retina can be attributed to the blood retinal barriers (BRB) of the retinal vasculature and the retinal pigment epithelium, which both tightly regulate the transport of small molecules and restrict passage of cells and macromolecules from the circulation into the retina in a similar fashion to the blood brain barrier (BBB).

Mosaic modularity: an updated perspective and research agenda for the evolution of vascular cambial growth.

New Phytol 2018 Dec 15. Epub 2018 Dec 15.

Pacific Southwest Research Station, USDA Forest Service, Davis, CA, 95618.

Secondary growth from a vascular cambium, present today only in seed plants and isoetalean lycophytes, has a 400-million-year evolutionary history that involves considerably broader taxonomic diversity, most of it hidden in the fossil record. Approaching vascular cambial growth as a complex developmental process, we review data from living plants and fossils that reveal diverse modes of secondary growth. These are consistent with a modular nature of secondary growth, when considered as a tracheophyte-wide structural feature. Read More

Periventricular Microglial Cells Interact with Dividing Precursor Cells in the Nonhuman Primate and Rodent Prenatal Cerebral Cortex.

J Comp Neurol 2018 Dec 15. Epub 2018 Dec 15.

Department of Pediatrics, School of Medicine, UC Davis, Davis, CA.

Cortical proliferative zones have been studied for over 100 years, yet recent data has revealed that microglial cells constitute a sizeable proportion of ventricular zone cells during late stages of cortical neurogenesis. Microglia begin colonizing the forebrain after neural tube closure and during later stages of neurogenesis populate regions of the developing cortex that include the proliferative zones. We previously showed that microglia regulate the production of cortical cells by phagocytosing neural precursor cells (NPCs), but how microglia interact with NPCs remains poorly understood.

Vascular anatomy of the free fibula flap including the lateral head of the soleus muscle applied to maxillo-mandibular reconstruction.

Surg Radiol Anat 2018 Dec 14. Epub 2018 Dec 14.

Department of Maxillo-Facial Surgery, Beaujon Hospital, AP-HP, 100 boulevard du Général Leclerc, 92110, Clichy, France.

Purpose: Initially described by Baudet in 1982, the fibula flap including the lateral head of the soleus muscle allows a one-stage reconstruction for large maxillo-mandibular defects. The aim of this study was to evaluate the number of muscular branches destined to the soleus muscle and their distance from the origin of the fibular artery, to assess the vascular anatomy of the free fibula flap including the lateral head of the soleus muscle applied to maxillo-mandibular reconstruction.

Methods: We performed a cadaveric anatomic study on ten lower limbs, and a CT angiography anatomic study on 38 legs. Read More

Skewed X-inactivation is common in the general female population.

Eur J Hum Genet 2018 Dec 14. Epub 2018 Dec 14.

Department of Human Genetics, Leiden University Medical Center, Leiden, The Netherlands.

X-inactivation is a well-established dosage compensation mechanism ensuring that X-chromosomal genes are expressed at comparable levels in males and females. Skewed X-inactivation is often explained by negative selection of one of the alleles. We demonstrate that imbalanced expression of the paternal and maternal X-chromosomes is common in the general population and that the random nature of the X-inactivation mechanism can be sufficient to explain the imbalance.

A Notch-regulated proliferative stem cell zone in the developing spinal cord is an ancestral vertebrate trait.

Development 2018 Dec 14. Epub 2018 Dec 14.

Department of Zoology, University of Oxford, 11a Mansfield Road, Oxford, OX1 3SZ, UK

Vertebrates have evolved the most sophisticated nervous systems we know. These differ from the nervous systems of invertebrates in several ways, including the evolution of new cell types, and the emergence and elaboration of patterning mechanisms to organise cells in time and space. Vertebrates also generally have many more cells in their central nervous systems than invertebrates, and an increase in neural cell number may have contributed to the sophisticated anatomy of the brain and spinal cord.

Circulating Exosomal miR-20b-5p is Elevated in Type 2 Diabetes and Could Impair Insulin Action in Human Skeletal Muscle.

Diabetes 2018 Dec 14. Epub 2018 Dec 14.

Department of Physiology and Pharmacology Karolinska Institutet, SE-171 77 Stockholm, Sweden,

MicroRNAs (miRNAs) are noncoding RNAs representing an important class of gene expression modulators. Extracellular circulating miRNAs are both candidate biomarkers for disease pathogenesis and mediators of cell-to-cell communication. We examined the miRNA expression profile of total serum and serum derived exosome-enriched extracellular vesicles in people with normal glucose tolerance or type 2 diabetes. Read More
