Parkinson's disease is a prevalent neurological condition that affects around 1% of adults over 60 worldwide. Deep brain stimulation and dopamine replacement therapy are common therapies for Parkinson's disease, yet they are unable to reverse the disease it simply because of the blood brain barrier. The use of bioengineered exosomes to treat Parkinson's disease is being studied because they have the ability to cross the blood-brain barrier.

Article Synopsis
  • Induction of labor (IOL) is increasingly common, particularly in high-income countries with more pregnant women facing health issues, raising concerns about higher cesarean section (CS) rates and the need for better delivery mode counseling.
  • The study aims to create a predictive model for vaginal delivery after IOL, as well as models for CS related to abnormal fetal heart rate and labor dystocia, using maternal clinical data and advanced computational techniques.
  • Results from a sample of 2,434 singleton pregnancies indicated the vaginal delivery model was quite effective (AUROC = 0.794), while the CS model was less discriminatory (AUROC = 0.590), highlighting the predictive power of certain labor-related factors.

Impact of walking on knee articular cartilage T2 values estimated with a dictionary-based approach - A pilot study.

Radiography (Lond)

November 2024

Centro Hospitalar Universitário de Santo António, Unidade Local de Saúde de Santo António, Orthopedic Department, Porto, Portugal; ICBAS, School of Medicine and Biomedical Sciences, University of Porto, Portugal. Electronic address:

Article Synopsis
  • Walking is important for the health of knee articular cartilage, but traditional MRI methods don't effectively detect early changes in cartilage composition due to exercise.
  • This study involved seven healthy volunteers, who had MRI scans of their knees before and after a 9-minute treadmill walk, to assess whether a quantitative T2 mapping technique could identify changes in cartilage related to water content.
  • The results showed that walking significantly increased T2 values in the knee cartilage, indicating changes in hydration that could be used for early detection of cartilage issues, particularly useful for at-risk patients.

Introduction: Follicular delivery is one of the targeted drug delivery methods aiming to target the hair follicles. The accumulation and retention time of targeted drugs is enhanced when nanoparticles are used as drug carriers. Particle size is one of the important factors affecting the penetration and accumulation of particles in the hair follicles, and there is a controversy in different studies for the best particle size for follicular delivery.

The role of chondroitin sulphate as a potential biomaterial for hepatic tissue regeneration: A comprehensive review.

Int J Biol Macromol

October 2024

Department of Human Nutrition and Dietetics, Faculty of Rehabilitation and Allied Health Sciences, Riphah International University, Gulberg III, Lahore 54000, Pakistan. Electronic address:

Chondroitin sulphate is an anionic hetero-polysaccharide, having numerous structural affinities for building the bio-active components. In addition to biodegradable/biocompatible activities, chondroitin sulphate also possesses anti-coagulant/anti-thrombogenic, anti-inflammatory, anti-oxidant as well as anti-tumor activities. Chondroitin sulphate has an inherited affinity for glycosylation enzymes and receptors, which are overexpressed over degenerated cells and organelles.
