AI Article Synopsis

  • - A 24-year-old patient from Cameroon came to the hospital with a foreign object in her left eye.
  • - Fluorescent microscopy was used to find moving microfilariae, confirming a diagnosis of loiasis for the first time.
  • - Even though she had high levels of microfilariae, eosinophilia (an increase in a type of white blood cell) only appeared after starting antiparasitic treatment.

Article Abstract

A 24-year-old patient from Cameroon presented to our hospital because of a foreign structure in her left eye. To our knowledge, for the first time, fluorescent microscopy revealed motile microfilariae, and the diagnosis of loiasis was established. Despite substantial microfilaremia, eosinophilia only unmasked after the initiation of antiparasitic therapy.

DFNA1 (deafness, nonsyndromic autosomal dominant 1), initially identified as nonsyndromic sensorineural hearing loss, has been associated with an additional symptom: macrothrombocytopenia. However, the timing of the onset of hearing loss (HL) and thrombocytopenia has not been investigated, leaving it unclear which occurs earlier. Here, we generated a knock-in (KI) DFNA1 mouse model, diaphanous-related formin 1 (DIA1), in which Aequorea coerulescens green fluorescent protein (AcGFP)-tagged human DIA1(p.

Alzheimer's disease (AD) is an age-related neurodegenerative pathology. Brain-derived extracellular vesicles (EVs) have been demonstrated to be implicated in AD pathogenesis by facilitating the propagation of Tau, amyloid-β and inflammatory cytokines. However, the impact of peripheral EVs (pEVs) in AD pathogenesis remains poorly investigated.

Calcium binding to troponin triggers the contraction of skeletal and heart muscle through structural changes in the thin filaments that allow myosin motors from the thick filaments to bind to actin and drive filament sliding. Here, we review studies in which those changes were determined in demembranated fibres of skeletal and heart muscle using fluorescence for in situ structure (FISS), which determines domain orientations using polarised fluorescence from bifunctional rhodamine attached to cysteine pairs in the target domain. We describe the changes in the orientations of the N-terminal lobe of troponin C (TnC) and the troponin IT arm in skeletal and cardiac muscle cells associated with contraction and compare the orientations with those determined in isolated cardiac thin filaments by cryo-electron microscopy.

α-Synuclein (αSyn), an intrinsically disordered protein implicated in Parkinson's disease, is potentially thought to initiate aggregation through binding to cellular membranes. Previous studies have suggested that anionic membrane charge is necessary for this binding. However, these studies largely focus on unmodified αSyn, while nearly all αSyn in the body is N-terminally acetylated (NTA).

The human genome contains numerous repetitive nucleotide sequences that display a propensity to fold into non-canonical DNA structures including G-quadruplexes (G4s). G4s have both positive and negative impacts on various aspects of nucleic acid metabolism including DNA replication, DNA repair and RNA transcription. Poly (ADP-ribose) polymerase (PARP1), an important anticancer drug target, has been recently shown to bind a subset of G4s, and to undergo auto-PARylation.
