Background: Congenital factor VII (FVII) deficiency is a genetic disorder characterized by decreased FVII activity, which sometimes leads to fatal bleeding. Numerous variants have been found in FVII deficiency, but mutations vary among patients. Each mutation deserves further exploration for each patient at risk of bleeding.

Methods based on density-functional theory usually treat open-shell atoms and molecules within the spin-unrestricted Kohn-Sham (KS) formalism, which breaks symmetries in real and spin space. Symmetry breaking is possible because the KS Hamiltonian operator does not need to exhibit the full symmetry of the physical Hamiltonian operator, but only the symmetry of the spin density, which is generally lower. Symmetry breaking leads to spin contamination and prevents a proper classification of the KS wave function with respect to the symmetries of the physical electron system.

Conventional scanned optical coherence tomography (OCT) suffers from the frame rate/resolution tradeoff, whereby increasing image resolution leads to decreases in the maximum achievable frame rate. To overcome this limitation, we propose two variants of machine learning (ML)-based adaptive scanning approaches: one using a ConvLSTM-based sequential prediction model and another leveraging a temporal attention unit (TAU)-based parallel prediction model for scene dynamics prediction. These models are integrated with a kinodynamic path planner based on the clustered traveling salesperson problem to create two versions of ML-based adaptive scanning pipelines.

Background: Congenital muscular dystrophies (CMDs) and myopathies (CMYOs) are a clinically and genetically heterogeneous group of neuromuscular disorders that share common features, such as muscle weakness, hypotonia, characteristic changes on muscle biopsy and motor retardation. In this study, we recruited eleven families with early-onset neuromuscular disorders in China, aimed to clarify the underlying genetic etiology.
Methods: Essential clinical tests, such as biomedical examination, electromyography and muscle biopsy, were applied to evaluate patient phenotypes.

Hereditary spastic paraplegias (HSPs) refer to a genetically and clinically heterogeneous group of neurodegenerative disorders characterized by the degeneration of motor neurons. To date, a significant number of patients still have not received a definite genetic diagnosis. Therefore, identifying unreported causative genes continues to be of great importance.
