Domain-Specific Cognitive Prosthesis for Face Memory and Recognition.

The present study proposes a cognitive prosthesis device for face memory impairment as a proof-of-concept for the domain-specific cognitive prosthesis. Healthy subjects (n = 6) and a patient with poor face memory were enrolled. An acquaintance face recognition test with and without the use of cognitive prosthesis for face memory impairment, face recognition tests, quality of life, neuropsychological assessments, and machine learning performance of the cognitive prosthesis were followed-up throughout four weeks of real-world device use by the patient.

Immunodetection of acetylated alpha-tubulin in stony corals: Evidence for the existence of flagella in coral male germ cells.

The molecular and cellular characteristics of male germ cell development remain largely unknown in corals. This study focused on the expression pattern of acetylated α-tubulin (Ac-α-Tu), which is involved in male germ cell development in various animals across taxa, to gain a better understanding of male germ cell development in the stony coral Euphyllia ancora. Immunohistochemical analysis of the different stages of male germ cells showed the presence of filamentous Ac-α-Tu in the early to late stages of male germ cells-such as spermatogonia, spermatocytes, and spermatids-as well as in the flagella of mature sperm.

Assessment of tumor growth in pancreatic neuroendocrine tumors in von Hippel Lindau syndrome.

Background: The incidence of pancreatic neuroendocrine tumors (PNETs) is increasing, but only a subset of these heterogeneous tumors will progress to malignant disease, which is associated with a poor prognosis. Currently, there are limited data on the natural history of these tumors and it is difficult to determine which patients require surgical intervention because the risk of metastatic disease cannot be accurately determined.

Study Design: We conducted a prospective study of 87 patients with von Hippel Lindau syndrome-associated solid pancreatic lesions to determine the natural history of these tumors with biochemical testing, follow-up anatomic and functional imaging, and advanced imaging analysis, with a median follow-up of 4 years.

Denosumab treatment for fibrous dysplasia.

Fibrous dysplasia (FD) is a skeletal disease caused by somatic activating mutations of the cyclic adenosine monophosphate (cAMP)-regulating protein, α-subunit of the Gs stimulatory protein (G(s) α). These mutations lead to replacement of normal bone by proliferative osteogenic precursors, resulting in deformity, fracture, and pain. Medical treatment has been ineffective in altering the disease course.

Optimizing computer-aided colonic polyp detection for CT colonography by evolving the Pareto fronta.

A multiobjective genetic algorithm is designed to optimize a computer-aided detection (CAD) system for identifying colonic polyps. Colonic polyps appear as elliptical protrusions on the inner surface of the colon. Curvature-based features for colonic polyp detection have proved to be successful in several CT colonography (CTC) CAD systems.
