Tree-ring width chronologies of Du Tour from near the upper treeline in the Western Sayan, Southern Siberia are found to have an exceptional (below mean-3SD) multi-year drop near 1700 CE, highlighted by the seven narrowest-ring years in a 1524-2022 regional chronology occurring in the short span of one decade. Tree rings are sometimes applied to reconstruct seasonal air temperatures; therefore, it is important to identify other factors that may have contributed to the growth suppression. The spatiotemporal scope of the "nosedive" in tree growth is investigated with a large network of (14 sites) and Ledeb.

Acquired reactive perforating dermatosis (ARPD) is characterized by its onset after the age of 18 years, umbilicated papules or nodules with a central keratotic plug, and the presence of necrotic collagen tissue within an epithelial crater. ARPD is strongly associated with systemic diseases such as diabetes mellitus (DM) and chronic renal failure, which may contribute to ARPD through factors including microcirculatory disturbances and the deposition of metabolic byproducts, including advanced glycation end-products and calcium. Here, we report a case of ARPD that improved following DM treatment and catheter-based interventions for peripheral artery disease (PAD).

Cutaneous (CLE) and systemic lupus erythematosus (SLE) are autoimmune diseases with a multifactorial pathogenesis. Ultraviolet radiation (UVR) is the most important trigger of CLE; however, the degree of photosensitivity varies between the clinical subtypes. The expression of matrix metalloproteinases (MMPs)-important enzymes involved in skin turnover and homeostasis-is modulated by UVR.

Jansen metaphyseal chondrodysplasia (JMC) is an ultra-rare disorder caused by constitutive activation of parathyroid hormone type 1 receptor (PTH1R). We sought to characterize the craniofacial phenotype of patients with the disease. Six patients with genetically confirmed JMC underwent comprehensive craniofacial phenotyping revealing a distinct facial appearance that prompted a cephalometric analysis demonstrating a pattern of mandibular retrognathia.

It is characterized by the sudden onset of asymptomatic small erythematous hemangioma-like papules encircled by a pale halo. The precise pathogenesis is unknown; however, multiple environmental triggers have been reported.
