Article Synopsis
  • Medium vessel occlusion (MeVO) strokes, especially in the M2 segment of the middle cerebral artery, are a significant challenge in stroke management, necessitating effective prediction of patient outcomes after mechanical thrombectomy (MT).
  • This study analyzed data from the MAD-MT registry to evaluate the relationship between follow-up infarct volume (FIV) and 90-day functional outcomes, using the modified Rankin Scale (mRS) as a measurement.
  • Results showed that FIV is a strong predictor of outcomes, with specific volume thresholds indicating favorable prognosis; notably, an FIV of ≤15 ml had the best predictive capability, outperforming traditional recanalization scores.

Article Synopsis
  • The study investigates the effectiveness and safety of two treatment methods for acute ischemic stroke (AIS) caused by distal medium vessel occlusion (DMVO): intravenous thrombolysis (IVT) with mechanical thrombectomy (MT) versus IVT alone.
  • Data was collected from 37 centers worldwide, involving over 1,000 patients, with the primary focus on functional independence at 90 days and secondary outcomes including mortality and intracerebral hemorrhage.
  • Findings suggest that both treatment options yield similar functional and mortality outcomes for DMVO patients, but the MT-IVT approach carries a higher risk of hemorrhagic complications, indicating that it may not provide significant advantages over IVT alone for every patient.

Article Synopsis
  • Mechanical thrombectomy is the standard treatment for large vessel occlusions, but there's limited evidence for its effectiveness in treating distal and medium vessel occlusions, particularly for patients with low stroke scale scores (≤6).
  • A study analyzed data from 41 academic centers, comparing outcomes of low versus higher stroke scale score patients who underwent thrombectomy, revealing high successful reperfusion rates in both groups.
  • Results showed that patients with lower stroke scale scores experienced better functional outcomes and lower mortality rates, but the treatment's effectiveness compared to intravenous thrombolysis (IVT) is still uncertain.

Locally adaptive inversions in structured populations.

Genetics

July 2024

Department of Genetics, Evolution, and Environment, University College London, Gower Street, London WC1E 6BT, UK.

Inversions have been proposed to facilitate local adaptation, by linking together locally coadapted alleles at different loci. Prior work addressing this question theoretically has considered the spread of inversions in "continent-island" scenarios in which there is a unidirectional flow of maladapted migrants into the island population. In this setting, inversions capturing locally adaptive haplotypes are most likely to invade when selection is weak, because stronger local selection (i) more effectively purges maladaptive alleles and (ii) generates linkage disequilibrium between adaptive alleles, thus lessening the advantage of inversions.

Gametic selection favours polyandry and selfing.

PLoS Genet

February 2024

School of Biological Sciences, University of East Anglia, Norwich, Norfolk, United Kingdom.

Competition among pollen or sperm (gametic selection) can cause evolution. Mating systems shape the intensity of gametic selection by determining the competitors involved, which can in turn cause the mating system itself to evolve. We model the bidirectional relationship between gametic selection and mating systems, focusing on variation in female mating frequency (monandry-polyandry) and self-fertilisation (selfing-outcrossing).

The Anopheles leucine-rich repeat protein APL1C is a pathogen binding factor recognizing Plasmodium ookinetes and sporozoites.

PLoS Pathog

February 2024

Institut Pasteur, Université de Paris, CNRS UMR2000, Unit of Genetics and Genomics of Insect Vectors, Department of Parasites and Insect Vectors, Paris, France.

Leucine-rich repeat (LRR) proteins are commonly involved in innate immunity of animals and plants, including for pattern recognition of pathogen-derived elicitors. The Anopheles secreted LRR proteins APL1C and LRIM1 are required for malaria ookinete killing in conjunction with the complement-like TEP1 protein. However, the mechanism of parasite immune recognition by the mosquito remains unclear, although it is known that TEP1 lacks inherent binding specificity.

Purpose: To investigate the relationship between the macular values of fractal dimension (FD) and lacunarity (LAC) on optical coherence tomography angiography (OCTA) images and the presence of peripheral retina non-perfusion areas (NPAs) on fluorescein angiography (FA) in patients with treatment-naïve diabetic macular edema (DME).

Methods: Fifty patients with treatment-naïve DME underwent a full ophthalmic examination, including best-corrected visual acuity measurement, FA, spectral-domain optical coherence tomography, and OCTA. Specifically, FA was performed to detect the presence of retinal NPAs, whereas fractal OCTA analysis was used to determine macular FD and LAC values at the level of the superficial and deep capillary plexus (SCP and DCP).

Finite-size scaling above the upper critical dimension is a long-standing puzzle in the field of statistical physics. Even for pure systems various scaling theories have been suggested, partially corroborated by numerical simulations. In the present manuscript we address this problem in the even more complicated case of disordered systems.
