Legumes enter nodule symbioses with nitrogen-fixing bacteria (rhizobia), whereas most flowering plants establish symbiotic associations with arbuscular mycorrhizal (AM) fungi. Once first steps of symbiosis are initiated, nodule formation and mycorrhization in legumes is negatively controlled by a shoot-derived inhibitor (SDI), a phenomenon termed autoregulation. According to current views, autoregulation of nodulation and mycorrhization in legumes is regulated in a similar way. CLE peptides induced in response to rhizobial nodulation signals (Nod factors) have been proposed to represent the ascending long-distance signals to the shoot. Although not proven yet, these CLE peptides are likely perceived by leucine-rich repeat (LRR) autoregulation receptor kinases in the shoot. Autoregulation of mycorrhization in non-legumes is reminiscent to the phenomenon of "systemic acquired resistance" in plant-pathogen interactions.

Introduction: The rate of nondiagnostic and indeterminate cytology findings from fine-needle aspiration biopsy (FNAB) is quite high, resulting in repeated puncture and unnecessary surgery. The primary objective of this investigation is to compare diagnostic accuracy of core-needle biopsy (CNB) with repeat FNAB for thyroid nodules with initially inconclusive (nondiagnostic and/or atypia of undetermined significance) FNAB results.

Miliarias are a group of eccrine disorders characterized by sweat retention due to the occlusion of eccrine ducts. Miliaria profunda is the rarest form of miliaria and occurs when eccrine ducts are obstructed at the dermal-epidermal junction. A granulomatous variant of centrifugal miliaria profunda classic findings of granulomatous infiltrate on histology and centrifugal expansion of deep nodules or plaques.

The GlnE enzyme, functioning as an adenylyltransferase/adenylyl-removing enzyme, plays a crucial role in reversible adenylylation of glutamine synthetase (GS), which in turn regulates bacterial nitrogen assimilation. Genomic analysis of Azorhizobium caulinodans ORS571 revealed an open reading frame encoding a GlnE protein, whose function in the free-living and symbiotic states remains to be elucidated. A glnE deletion mutant retained high GS activity even under nitrogen-rich conditions.

Chromium-based functional coatings (CFCs) are widely recognized for their outstanding wear and corrosion resistance across diverse industrial sectors. However, despite advancements in deposition techniques and microstructural enhancements, many contemporary CFCs remain vulnerable to degradation in highly corrosive environments. For the first time, this research delivers a thorough characterization of the corrosion resistance of advanced CFCs, focusing on the performance of a 5 μm thin dense chromium (TDC) coating.
