Percussion Massage Therapy Reduced EMG Activity During Standing Heel Raise.

Objectives: This study examined the acute impact of percussion massage therapy (PMT) on calf muscle activation during heel raises in individuals with and without chronic ankle instability (CAI).

Methods: Thirty-nine university students, 20 with CAI and 19 controls, were randomized to 30 seconds of PMT or no intervention (NOPMT). Surface EMG measured medial gastrocnemius activity during heel raise before and after.

Abnormalities of thalamus and thalamocortical pathways in patients with refractory epilepsy caused by focal cortical dysplasia - MRI study.

Objective: Drug-resistant epilepsy, a severe and diagnostically challenging neurological condition often linked to focal cortical dysplasia (FCD), represents a significant social and healthcare burden. While the thalamus is notably altered in this disorder, it remains unclear whether these changes result from epilepsy manifestation or participate in its pathophysiology. This study aimed to characterize volumetric and microstructural changes in the thalamus and thalamocortical pathways in epilepsy patients with FCD.

Newly identified cerebral microbleeds in patients on anticoagulation for secondary stroke prevention.

Patients with cardioembolic ischemic stroke are commonly prescribed direct oral anticoagulants (DOACs), such as dabigatran (a direct thrombin inhibitor) and factor Xa inhibitors (e.g., apixaban and rivaroxaban), or warfarin to reduce the risk of recurrent stroke.

Possible charge ordering and anomalous transport in graphene/graphene quantum dot heterostructure.

Observations of superconductivity and charge density waves (CDW) in graphene have been elusive thus far due to weak electron-phonon coupling (EPC) interactions. Here, we report a unique observation of anomalous transport and multiple charge ordering phases at high temperatures (T1∼213K,T2∼325K) in a 0D-2D van der Waals (vdW) heterostructure comprising of single layer graphene (SLG) and functionalized (amine) graphene quantum dots (GQD). The presence of functionalized GQD contributed to charge transfer with shifting of the Dirac point ∼ 0.

Long-Range Magnetic Order in Nickel Hydroxide-Functionalized Graphene Quantum Dots.

In this work, we demonstrate the prospect of chemically synthesizing transition metal (Ni) doped magnetic graphene quantum dots (GQDs) with the sole aim of shedding light on their magnetic properties. Our results show that adsorption of nickel hydroxide on predominantly paramagnetic GQDs reveals antiferromagnetic ordering in the M-T profile around 10 K with change of the spin exchange coupling deviating from = 1/2 to = 1, mainly arising from the d-p mixing hybridization between the p orbital of carbon from the GQD and the d orbital of Ni. Furthermore, our results are well complemented by simulations showing asymmetry of the up and down spins around the Fermi level for nickel hydroxide-doped GQDs with long-range spin polarization.

Probing the charge transfer and electron-hole asymmetry in graphene-graphene quantum dot heterostructure.

In recent years, graphene-based van der Waals (vdW) heterostructures have come into prominence showcasing interesting charge transfer dynamics which is significant for optoelectronic applications. These novel structures are highly tunable depending on several factors such as the combination of the two-dimensional materials, the number of layers and band alignment exhibiting interfacial charge transfer dynamics. Here, we report on a novel graphene based 0D-2D vdW heterostructure between graphene and amine-functionalized graphene quantum dots (GQD) to investigate the interfacial charge transfer and doping possibilities.
