To demonstrate the utility of somatosensory evoked potentials (SEPs) following median nerve stimulation for chronological assessment of sensory function in patients with subacute stroke during rehabilitation. Retrospective study. Forty-seven patients with hemiparesis due to stroke during the subacute phase.

We present a case of an elderly man with a subcutaneous nodule in his lower leg that had persisted for four decades, accompanied by pain in the last several years. Imaging revealed a 20-mm elongated subcutaneous nodule along with a similar intraosseous lesion in the ipsilateral fibula.

Article Synopsis
- The study aimed to analyze the imaging characteristics of the gubernaculum tract (GT) in patients with cleidocranial dysplasia (CCD) using computed tomography (CT).
- It found a high detection rate of GTs for both unerupted permanent teeth (83.5%) and supernumerary teeth (83.1%), with no significant differences between the two.
- The results suggest that a specific structure involving GTs and dental follicles may indicate that multiple teeth could originate from a single dental lamina, potentially leading to eruption failures.
Article Synopsis
- A sustainable society needs advanced energy storage devices that are lightweight, compact, long-lasting, and safe, going beyond current battery and supercapacitor technologies.
- Single-walled carbon nanotubes (SWCNTs) show promise for this purpose, as they are tough and can be formed into ropes that store nanomechanical energy.
- These SWCNT ropes can store energy with a density of up to 2.1 MJ/kg, which is significantly higher than mechanical steel springs and three times more than advanced lithium-ion batteries, while also being stable and safe in extreme temperatures.
Association between lymph node ratio and survival outcomes in patients with oral squamous cell carcinoma.

Article Synopsis
- * A study involving 152 OSCC patients, all with confirmed lymph node metastasis, demonstrated a significant correlation between LNR and both overall survival (OS) and recurrence-free survival (RFS).
- * The results indicated that patients with a high LNR (≥ 0.095) had a worse prognosis compared to those with a low LNR (< 0.095), identifying LNR as a potential independent prognostic factor in OSCC.
