Lumbar and Thoracic Vertebrae Segmentation in CT Scans Using a 3D Multi-Object Localization and Segmentation CNN

open access: yesTomography
Radiation treatment of cancers like prostate or cervix cancer requires considering nearby bone structures like vertebrae. In this work, we present and validate a novel automated method for the 3D segmentation of individual lumbar and thoracic vertebra in

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Discourse segmentation and the management of multiple tasks in single episodes of air traffic controller-pilot spoken radio communication

open access: yesDiscours, 2009
Episodes of VHF radio-mediated pilot-controller spoken communication in which multiple tasks are conducted are engendered in and through the skilful deployment and combination, by the parties to the talk, of multiple orders of discourse segmentation ...

Segmental neurofibromatosis

open access: yesDermatology Online Journal, 2011
A 59-year-old man presented for evaluation and excision of non-tender, fleshy nodules that were arranged in a dermatomal distribution from the left side of the chest to the left axilla. A biopsy specimen of a nodule was consistent with a neurofibroma. Owing to the lack of other cutaneous findings, the lack of a family history of neurofibromatosis, and ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Segmenting discourse: Incorporating interpretation into segmentation? [PDF]

open access: yesCorpus Linguistics and Linguistic Theory, 2018
AbstractDiscourse segmentation is an important step in the process of annotating coherence relations. Ideally, implementing segmentation rules results in text segments that correspond to the units of thought related to each other. This paper demonstrates that accurate segmentation is in part dependent on the propositional content of text fragments, and

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Vitamin D supplementation trials: Navigating the maze of unpredictable results

open access: yesPerspectives in Clinical Research
Vitamin D supplementation studies in various pleiotropic outcomes often yield conflicting results. This complexity arises from various factors, including individual differences (baseline Vitamin D levels, genetics, ethnicity, age, and gender).
