This paper presents parameter estimation for the passive moment and musculoskeletal scaling coefficients of a mathematical model describing the equations of motion of human finger segments. A novel musculoskeletal model was used as the actuator and parameter estimation was performed by least squares optimization of the differences between angular data from a motion capture system, and the solutions to the equations of motion of our model. The parameter estimates determined are unique to the individual and the dataset. Model fits show good agreement with filtered data R = 0.98. The hope is that this model and approach can be used to determine the passive moment and musculoskeletal scaling coefficients for all types of grasps.

Non-targeted metabolomic study in plasma in rats with post-traumatic osteoarthritis model.

Purpose: This study aimed to examine the differential expression profiles of plasma metabolites in rat models of post-traumatic osteoarthritis (PTOA) and elucidate the roles of metabolites and their pathways in the progression of PTOA using bioinformatics analysis.
Method: Plasma samples were collected from 24 SD female rats to model PTOA, and metabolomic assays were conducted. The samples were divided into three groups: the surgically induced mild PTOA group (Group A: 3 weeks postoperative using the modified Hulth model; age 2 months), the surgically induced severe PTOA group (Group B: 5 weeks postoperative using the modified Hulth model; age 2 months), and the normal control group (Group C: healthy rats aged 2 months).
A methodological framework for deriving the German food-based dietary guidelines 2024: Food groups, nutrient goals, and objective functions.
PLoS One
March 2025
Department of Physiology and Biochemistry of Nutrition, Max Rubner-Institut, Karlsruhe, Germany.
Background: For a growing number of food-based dietary guidelines (FBDGs), diet optimization is the tool of choice to account for the complex demands of healthy and sustainable diets. However, decisions about such optimization models' parameters are rarely reported nor systematically studied.
Objectives: The objectives were to develop a framework for (i) the formulation of decision variables based on a hierarchical food classification system; (ii) the mathematical form of the objective function; and (iii) approaches to incorporate nutrient goals.
An Integrated Fuzzy Neural Network and Topological Data Analysis for Molecular Graph Representation Learning and Property Forecasting.
Mol Inform

Faculty of Information Technology, HUTECH University, Ho Chi Minh City, Vietnam.
Within a recent decade, graph neural network (GNN) has emerged as a powerful neural architecture for various graph-structured data modelling and task-driven representation learning problems. Recent studies have highlighted the remarkable capabilities of GNNs in handling complex graph representation learning tasks, achieving state-of-the-art results in node/graph classification, regression, and generation. However, most traditional GNN-based architectures like GCN and GraphSAGE still faced several challenges related to the capability of preserving the multi-scaled topological structures.

Obesity is associated with comorbidities including type 2 diabetes, chronic nonhealing wounds, and psoriasis. Normally, skin homeostasis and repair is regulated through the production of cytokines and growth factors derived from skin-resident cells including epidermal γδ T cells. However, epidermal γδ T cells exhibit reduced proliferation and defective growth factor and cytokine production during obesity and type 2 diabetes.

Postoperative abdominal adhesions are the leading cause of bowel obstruction and a cause of chronic pain and infertility. Adhesion formation occurs after 50 to 90% of abdominal operations and has no proven preventative or treatment strategy. Abdominal adhesions derive primarily from the visceral peritoneum and are composed of polyclonally proliferating tissue-resident fibroblasts.
