Clinical Spectrum of Hemolytic Anemia in Loxoscelism: Report of Two Cases Highlighting Variable Severity and Management. [PDF]

Case Rep Hematol
Loxoscelism can cause local as well as systemic manifestations. Hematologic complications of brown recluse spider venom can be life‐threatening. Here, we present two cases of loxoscelism‐mediated hemolysis that highlight the variable clinical presentations and treatment options available based on severity and pathophysiology of hemolysis.

Renal Autotransplantation After Yang-Monti Neoureter Procedure: Surgical Case Report and Brief Literature Review. [PDF]

Case Rep Urol
Purpose Ureteral strictures are a well‐documented pathology in urology, commonly resulting from congenital anomalies, iatrogenic injury, or other acquired conditions such as infection, trauma, or radiation. While ischemic and nonischemic strictures are recognized, bilateral idiopathic ureteral strictures remain rare, particularly when associated with ...

Advances in the reconstruction of the spider tree of life: A roadmap for spider systematics and comparative studies

Cladistics, Volume 39, Issue 6, Page 479-532, December 2023., 2023
Abstract In the last decade and a half, advances in genetic sequencing technologies have revolutionized systematics, transforming the field from studying morphological characters or a few genetic markers, to genomic datasets in the phylogenomic era. A plethora of molecular phylogenetic studies on many taxonomic groups have come about, converging on, or

Spider Silk Protein Forms Amyloid‐Like Nanofibrils through a Non‐Nucleation‐Dependent Polymerization Mechanism

Small, Volume 19, Issue 46, November 15, 2023., 2023
Both spidroin and Alzheimer's disease associated amyloid‐β peptide capped by spidroin terminal domains can assemble into silk‐like fibers that consist of straight nanofibrils in normal physiological‐like buffer. Spidroins′ unique primary structures have evolved to allow functional amyloid‐like properties, and at the same time direct their ...

Aliens in caves: the global dimension of biological invasions in subterranean ecosystems

Biological Reviews, Volume 98, Issue 3, Page 849-867, June 2023., 2023
ABSTRACT Alien species are a significant threat to natural ecosystems and human economies. Despite global efforts to address this challenge, the documented number of alien species is rapidly increasing worldwide. However, the magnitude of the impact of alien species may vary significantly across habitats.
