Leishmania species, members of the kinetoplastid parasites, cause leishmaniasis, a neglected tropical disease, in millions of people worldwide. Leishmania has a complex life cycle with multiple developmental forms, as it cycles between a sand fly vector and a mammalian host; understanding their life cycle is critical to understanding disease spread. One of the key life cycle stages is the haptomonad form, which attaches to insect tissues through its flagellum.

Background: In previous Japanese subgroup/subset analyses of the global INBUILD trial, nintedanib reduced the annual rate of forced vital capacity (FVC) decline and the risk of disease progression in patients with progressive fibrosing interstitial lung diseases (PF-ILDs). This exploratory subset analysis assessed the effect of nintedanib on symptoms and impacts of pulmonary fibrosis in Japanese patients with PF-ILDs, including those with usual interstitial pneumonia (UIP)-like fibrotic pattern on high-resolution computed tomography (HRCT).

Methods: This analysis included Japanese patients who received at least one dose of study treatment in the randomized, double-blind, placebo-controlled INBUILD trial.

Article Synopsis
  • Embryo contour extraction is crucial for analyzing embryo morphology and understanding development, particularly with advancements in light-sheet microscopy for imaging embryos like zebrafish.
  • Recent challenges in extracting embryo contours from light-sheet images are addressed by a new workflow using edge detection and change point detection that does not require contour labeling.
  • This method outperforms traditional edge detection techniques in both accuracy and noise robustness, making it a valuable tool for automated contour extraction in situations where other methods, like deep learning approaches, are not feasible.

Attachment to a substrate to maintain position in a specific ecological niche is a common strategy across biology, especially for eukaryotic parasites. During development in the sand fly vector, the eukaryotic parasite adheres to the stomodeal valve, as the specialised haptomonad form. Dissection of haptomonad adhesion is a critical step for understanding the complete life cycle of .

Amoebae are found all around the world and play an essential role in the carbon cycle in the environment. Therefore, the behavior of amoebae is a crucial factor when considering the global environment. Amoebae change their distribution through amoeboid locomotion, which are classified into several modes.

Controlling the initiation of cell migration plays a fundamental role in shaping the tissue during embryonic development. During gastrulation in zebrafish, some mesendoderm cells migrate inward to form the endoderm as the innermost germ layer along the yolk syncytial layer. However, how the initiation of inward migration is regulated is poorly understood.

We previously revealed that the mechanism of demosponge skeleton construction is self-organization by multiple rounds of sequential mechanical reactions of player cells. In these reactions, "transport cells" dynamically carry fine skeletal elements (spicules) on epithelia surrounding the inner body space of sponges (basal epithelium (basopinacoderm) and the endodermal epithelium (ENCM)). Once spicules pierce ENCM and apical pinacoderm, subsequently they are cemented to the substratum under the sponge body, or connected to other skeleton-constructing spicules.

The way in which the central nervous system (CNS) governs animal movement is complex and difficult to solve solely by the analyses of muscle movement patterns. We tackle this problem by observing the activity of a large population of neurons in the CNS of larval . We focused on two major behaviors of the larvae - forward and backward locomotion - and analyzed the neuronal activity related to these behaviors during the fictive locomotion that occurs spontaneously in the isolated CNS.

Introduction: Following approval of dabigatran and other antithrombotics in Japan, few studies have specifically evaluated the clinical characteristics of patients prescribed these antithrombotics for nonvalvular atrial fibrillation (NVAF) in real-world practice.

Methods: We conducted a descriptive analysis of data from two real-world studies [J-dabigatran surveillance and Japanese study on current Anticoagulation therapies for Patients with nonvalvular Atrial Fibrillation (JAPAF); conducted at sites common to both studies] to determine the characteristics of patients with NVAF initiated on dabigatran etexilate [110 mg twice daily (BID; DE110) or 150 mg BID (DE150)], warfarin, rivaroxaban, or antiplatelets as their first antithrombotic treatment. Inferential statistical analyses were not performed, and no statistical hypothesis was tested.

Green-to-red photoconvertible fluorescent proteins have been found to undergo efficient photoconversion by a new method termed primed conversion that uses dual wave-length illumination with blue and red/near-infrared light. By modifying a confocal laser-scanning microscope (CLSM) such that two laser beams only meet at the focal plane, confined photoconversion at the axial dimension has been achieved. The necessity of this custom modification to the CLSM, however, has precluded the wide-spread use of this method.
