Chronotropic incompetence (CTI), the inability of the heart to increase its rate with increased activity, leads to exercise intolerance and predicts overall mortality. We previously reported that cardiac β-adrenergic receptor downregulation occurs in patients with CTI without heart failure (HF), indicating postsynaptic sympathetic nervous dysfunction. However, cardiac presynaptic sympathetic nervous system function in CTI is not fully understood.

Article Synopsis
  • On-site infection diagnosis requires compact, sensitive assays that are easy to use, but current technologies often need skilled technicians.
  • The D-strip is a new Point-of-Care Testing (PoCT) platform that merges digital enzyme-linked immunoassay (ELISA) with lateral flow assay (LFA), offering high sensitivity and minimal user intervention.
  • The D-strip provides results in 15 minutes with a limit of detection for SARS-2-CoV that is significantly better than conventional LFAs, positioning it as a promising tool for testing outside clinical labs.

Antiferromagnetic magnons possess a distinctive feature absent in their ferromagnetic counterparts: the presence of two distinct handedness modes, the right-handed (RH) and left-handed (LH) precession modes. The magnon handedness determines the sign of spin polarization carried by the propagating magnon, which is indispensable for harnessing the diverse functionalities in magnonic devices, such as data encoding, magnon polarization-based logic systems, and quantum applications involving magnons. However, the control of coherently propagating magnon handedness in antiferromagnets has remained elusive.

Article Synopsis
  • * Imaging tests revealed multiple brain and lung nodules, and blood tests indicated symptoms consistent with hemophagocytic syndrome.
  • * A bone marrow examination confirmed the presence of Toxoplasma gondii, leading to treatment; however, the patient ultimately developed multiple organ failure and died shortly after admission.

Introduction: This is a case of a 32-year-old woman who developed postpartum depression (PPD). She became anxious and depressive about caring for her child, and the Edinburgh Postnatal Depression Scale (EPDS) test showed a score of 9 at 2 weeks after delivery, and at 7 months postpartum, she presented with major melancholic depression followed by mild cognitive decline without any neurological symptoms except cluttering speech.

Case Presentation: Cerebral magnetic resonance imaging showed confluent fluid-attenuated inversion recovery hyperintensities in the periventricular and frontal deep white matter, with multiple spotty calcifications in the frontal white matter by cerebral CT.
