A 46-year-old, previously healthy woman presented via telemedicine with 14 months of progressive asymmetrical weakness, numbness, paresthesias and tremors. History and clinical exam findings suggested a peripheral etiology resembling a variant CIDP presentation. Electrodiagnostic testing identified only one motor nerve with signs of demyelination; the remainder of motor and sensory nerves were unable to be evoked. MRI showed diffuse enhancement of the trigeminal nerve and cauda equina. CSF revealed albuminocytologi [...]

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy causing non-ovulation infertility in women. Women with PCOS have higher levels of luteinizing hormone (LH), testosterone, cholesterol and triglycerides but, in contrast, lower levels of follicular stimulating hormone (FSH) and sex hormone-binding globulin (SHBG) compared with healthy counterparts. Because of the limitations of human studies, animal models of PCOS have been developed to identify appropriate therapeutics and to explore their mechanism [...]

Allogeneic hematopoietic stem cell transplantation is a curative therapy for hematological malignancies, but its efficacy is limited by graft-versus-host disease (GVHD). This life-threatening disorder develops when donor (graft) immune cells cause inflammatory damage to recipient (host) tissues. The immune cell receptor channel P2X7 and its ligand adenosine 5’-triphosphate (ATP) have been implicated in GVHD pathogenesis. Therefore, this signaling axis represents a potential therapeutic target. This study aime [...]

Chronic cancer pain results from the complex interaction of nociceptive, neuropathic, and neuroimmune mechanisms, which vary according to tumor type, location, stage, and treatment history. Recent advances in cancer neuroscience have reframed pain as a dynamic manifestation of reciprocal tumor–nerve–immune interactions, rather than a mere consequence of tissue damage. In this model, malignant, stromal, and immune cells remodel nociceptive circuits at peripheral and central levels. This narrative review, conducted i [...]

Certain observable parenting behaviors contribute to the risk of children developing internalizing and externalizing problems. Yet parenting behaviors do not affect all children uniformly and effects may depend on identifiable child characteristics. One factor is a child’s biological sensitivity to the caregiving environment, an indicator of which is a stress hormone, cortisol. This longitudinal study examines two dimensions of observable parenting behaviors, responsive and rejecting/harsh. These parenting behavior [...]

Hepatitis B virus (HBV) infection is frequent among patients with chronic kidney disease (CKD). HBV reactivation after kidney transplant (KT) is more common in patients with HBsAg+; however, it can also occur in previously infected individuals, particularly those with HBsAg negative and total antiHBc positive (HBsAg-/antiHBcT+). However, reactivation in this population has scarce and conflicting data. This study aimed to assess the reactivation risk in KT recipients with previous HBV infection (antiHBcT+). A retros [...]

Focusing upon the United Kingdom reveals that centralised provisions of energy have historically failed to uphold standards of human rights. Even if a transition is made to renewable energy, existing centralised distribution systems cannot promise improvement. This work would recommend the transition to domestic renewables, whereby energy is harnessed and used in situ, as it may support the more desirable notion of social justice with regard to energy usage. Domestic renewables are likely to become an inevitability [...]

TiO2 photocatalyst was prepared using cellulase as a biotemplate through a hydrothermal process. The as-prepared catalyst was characterized based on physicochemical techniques and was used to remove As(III) from contaminated water. The cellulase templated TiO2 photocatalyst (TiO2-cellulase) had a large specific surface area, which reached 166.6 m2·g–1. It also had a strong oxidation ability and, thus, behaved well in both photocatalytic oxidation of As(III) and dark adsorption. The pH of the solution h [...]

The escalating prevalence of vision loss due to eye diseases has instigated a quest for innovative therapies, given that conventional approaches often fall short in repairing and regenerating damaged eye tissues, particularly the retina. Stem cell-based interventions have emerged as a promising avenue, with numerous studies in animal models and human trials exploring their potential to enhance visual acuity. Beyond addressing conditions like age-related macular degeneration (AMD) and diabetic retinopathy (DR), stem [...]
