Genome-Wide siRNA Screen Identifies Complementary Signaling Pathways Involved in Listeria Infection and Reveals Different Actin Nucleation Mechanisms during Listeria Cell Invasion and Actin Comet Tail Formation

mBio, 2015
Listeria monocytogenes enters nonphagocytic cells by a receptor-mediated mechanism that is dependent on a clathrin-based molecular machinery and actin rearrangements.

Primary cardiac T‐cell rich large B‐cell lymphoma causing aortic stenosis with metastasis in a Warmblood

Equine Veterinary Education, EarlyView.
Summary An 18‐year‐old Warmblood mare was presented to the Royal Veterinary College Equine Referral Hospital for investigation of progressive periocular and facial swelling, weight loss and tachycardia. Physical examination additionally identified bilateral pansystolic (grade 5/6 basilar left‐sided, 2/6 right‐sided), cardiac murmurs, submandibular ...

Surgical management of recurrent oesophageal obstruction in a yearling Saddlebred filly

Equine Veterinary Education, EarlyView.
Summary This case report describes the diagnostic approach and surgical management of a yearling Saddlebred filly with recurrent oesophageal obstruction, likely caused by an acquired extraluminal oesophageal stricture. The filly initially presented with repeated episodes of oesophageal obstruction, which were resolved with sedation and nasogastric ...

Older Adults' Self‐Care and Family Caregiver Contribution in Multiple Chronic Conditions: A Dyadic Qualitative Study

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aims To explore how older adult‐family caregiver dyads jointly manage multiple chronic conditions. Specifically, it investigates how dyads (i) prioritise chronic diseases, (ii) make and negotiate decisions related to self‐care and (iii) define and distribute self‐care tasks and caregiver contributions.

Multiple Mechanisms Driving F-actin-Dependent Transport of Organelles to and From Secretory Sites in Bovine Chromaffin Cells

Frontiers in Cellular Neuroscience, 2018
Neuroendocrine chromaffin cells represent an excellent model to study the molecular mechanisms associated with the exo-endocytotic cycle of neurotransmitter release.

Molecular ions in comet tails

The Astrophysical Journal, 1976
Band intensities of the molecular ions CH/sup +/, CO/sup +/, N/sub 2//sup +/, and H/sub 2/O/sup +/ have been determined on an absolute scale from tail spectra of comet Kohoutek (1973f) and comet Bradfield (1974b). Photoionization and photodissociation rates have been computed for CH, CO, and N/sub 2/.

Visualizing DNA single- and double-strand breaks in the Flash comet assay by DNA polymerase-assisted end-labelling

Nucleic Acids Research
In the comet assay, tails are formed after single-cell gel electrophoresis if the cells have been exposed to genotoxic agents. These tails include a mixture of both DNA single-strand breaks (SSBs) and double-strand breaks (DSBs). However, these two types

Scaling of internal joint distance in the elbow of small‐ to medium‐sized mammals: Implications for range of motion analyses

Journal of Anatomy, EarlyView.
We investigated the internal joint distances (IJDs) of the humero‐ulnar and humero‐radial joint, within a sample of 15 small‐ to medium‐sized mammals and report isometric results. We also found that joint poses had no effect on IJDs and that IJDs scale isometrically within small species.

The PagDMG6341–PagWD40–PagPOLD4 Module Coordinates Base Excision Repair in ‘84K’ Poplar (Populus alba × P. glandulosa)

Plant Biotechnology Journal, EarlyView.
ABSTRACT Base excision repair (BER) is a critical pathway for repairing damaged DNA bases in cells; however, the mechanisms of protein recruitment and interaction in this pathway remain largely unexplored in higher plants. In this study, we used ‘84K’ poplar (Populus alba × P.

The Earth and Comets' Tails [PDF]

Scientific American, 1910
IN spite of the unreserved predictions of astronomers, the earth did not pass through the tail of Halley's comet on May 18–19, nor subsequently. The tail as seen in the morning sky, previous to the transit of the comet across the sun's disc, appeared like a long and straight beam of light stretching from the horizon to Aquila.
