Introduction: Traumatic brain injury (TBI) is a global health issue and a leading cause of long-term disabilities and mortality worldwide. There is growing evidence that TBI rehabilitation should be differentiated and individualised according to gender to provide more effective healthcare and rehabilitation. However, there is a lack of reviews focusing on the rehabilitation for women with TBI and there is a need to summarise existing knowledge to guide and individualise their rehabilitation.

We present a study on nanoscale skyrmionic spin textures in [Formula: see text], a rare-earth complex noncollinear ferromagnet. We confirm, using X-ray microscopy, that [Formula: see text] can host lattices of metastable skyrmion bubbles at room temperature in the absence of a magnetic field, after applying a suitable field cooling protocol. The skyrmion bubbles are robust against temperature changes from room temperature to 330 K.

Objectives: Facial width-to-height ratio (fWHR) has been widely investigated in the context of its role in visual communication, though there is a lack of consensus about how fWHR serves as a social signal. To better understand fWHR variation in a comparative context, we investigate the associations between fWHR and canine crown height (CCH) and body mass, respectively, among two chimpanzee subspecies (Pan troglodytes schweinfurthii, Pan troglodytes troglodytes) and bonobos (Pan paniscus).

Materials And Methods: We collected landmark data from 3D surface models of 86 Pan cranial specimens to quantify fWHR and upper CCH, and to estimate body mass.

Background: Some studies have shown that the incidence of type 2 diabetes increases after a diagnosis of COVID-19, although the evidence is not conclusive. However, the effects of the COVID-19 vaccine on this association, or the effect on other diabetes subtypes, are not clear. We aimed to investigate the association between COVID-19 and incidence of type 2, type 1, gestational and non-specific diabetes, and the effect of COVID- 19 vaccination, up to 52 weeks after diagnosis.

Epstein-Barr virus (EBV) infection has long been associated with the development of multiple sclerosis (MS). MS patients have elevated titers of EBV-specific antibodies in serum and show signs of CNS damage only after EBV infection. Regarding CD8+ T-cells, an elevated but ineffective response to EBV was suggested in MS patients, who present with a broader MHC-I-restricted EBV-specific T-cell receptor beta chain (TRB) repertoire compared to controls.

An antiferromagnet emits spin currents when time-reversal symmetry is broken. This is typically achieved by applying an external magnetic field below and above the spin-flop transition or by optical pumping. In this work we apply optical pump-THz emission spectroscopy to study picosecond spin pumping from metallic FeRh as a function of temperature.

Article Synopsis
  • Genome instability is a key feature of cancer, influenced by mutations in oncogenes and tumor suppressor genes, as well as numerous passenger mutations that don't affect tumor growth.
  • Personalized medicine strategies, like targeted therapies, only effectively treat a small group of patients with specific genetic mutations; however, many tumors have mutations that confer no advantage.
  • In studies involving prostate and ovarian cancers, loss of the NUDT15 gene—linked to hypersensitivity to thiopurines—was observed in a significant portion of cases, leading to the hypothesis that thiopurine and xanthine oxidase inhibition could lower cancer incidence, as verified by analysis of veteran patient data.

Background: Use of natalizumab (NTZ) is precluded in many Multiple Sclerosis (MS) patients by the risk of progressive multifocal leukoencephalopathy (PML). Regardless, some patients may commence natalizumab for short term disease control in spite of being seropositive, and others may seroconvert whilst on treatment. In these circumstances, discontinuation of NTZ should not occur until a clear exit strategy is established to prevent post-NTZ disease reactivation, which often exceeds the severity of disease activity prior to NTZ treatment.

Article Synopsis
  • - This study compared the effectiveness of autologous haematopoietic stem cell transplantation (AHSCT) and natalizumab in patients with progressive multiple sclerosis (MS), highlighting that AHSCT did not significantly improve disability compared to natalizumab.
  • - Researchers matched 39 patients treated with AHSCT to 65 patients on natalizumab and found no significant differences in confirmed disability worsening or improvement over a period of up to 4 years.
  • - Although AHSCT had some complications like febrile neutropenia and serum sickness, there were no treatment-related deaths, but the results suggest AHSCT is not effective for controlling disability in progressive MS patients with advanced disability and low relapse activity. *
