Electron Microscopy Reveals Inhomogeneous Adsorption of Iodine and Concurrent Defect Formation in a Metal-Organic Framework.
J Am Chem Soc
January 2025
Center for Electron Microscopy, South China University of Technology, Guangzhou 511436, China.
Adsorption behaviors are typically examined through adsorption isotherms, which measure the average adsorption amount as a function of partial pressure or time. However, this method is incapable of identifying inhomogeneities across the adsorbent, which may occur in the presence of strong intermolecular interactions of the adsorbate. In this study, we visualize the adsorption of molecular iodine (I) in the metal-organic framework material MFM-300(Sc) using high-resolution scanning transmission electron microscopy (STEM).

Indian J Ophthalmol
February 2025
Department of Orbit, Oculoplasty, Reconstructive and Aesthetic Services, Sankara Nethralaya, Medical Research Foundation, Chennai, Tamil Nadu, India.
Purpose: To present the clinical features and management outcomes in a series of patients with orbital and adnexal sarcoidosis.
Methods: This was a retrospective analysis of 19 histopathologically proven cases of orbital and adnexal sarcoidosis over the past ten years. The data analyzed included demographic details, clinical and imaging features, and management outcomes.
Eye Movements and the Intraorbital Subarachnoid Space: Potential Contribution of Altered Cerebrospinal Fluid Pumping in Optic Neuropathies.
Invest Ophthalmol Vis Sci
January 2025
Department of Ophthalmology, University of California, Los Angeles, California, United States.
Purpose: The optic nerve (ON) is mechanically perturbed by eye movements that shift cerebrospinal fluid (CSF) within its surrounding dural sheath. This study compared changes in ON length and CSF volume within the intraorbital ON sheath caused by eye movements in healthy subjects and patients with optic neuropathies.
Methods: Twenty-one healthy controls were compared with 11 patients having primary open angle glaucoma (POAG) at normal intraocular pressure (IOP), and 11 with chronic non-arteritic anterior ischemic optic neuropathy (NA-AION).
A Case of Severe Lupus and Refractory Anemia.
Cureus
December 2024
Internal Medicine, Hospital da Senhora da Oliveira, Guimarães, PRT.
Systemic lupus erythematosus (SLE) is a multisystemic connective tissue disease with a wide range of clinical and laboratory manifestations. The diagnosis of SLE is often challenging due to the great variability in its presentation, and treatment should be individualized according to the patient's manifestations and affected organs. We present the clinical case of a 25-year-old female who developed SLE with severe hematological and renal involvement as first manifestations, including hemolytic anemia, thrombocytopenia, and nephrotic syndrome.

Plant Dis
January 2025
INRAE Grand Est-Colmar, 28 rue de Herrlisheim, Colmar, France, 68000;
Esca is the most destructive and predominant of grapevine trunk disease. The chronic infections and vine mortality caused by esca syndrome leads to huge economic losses and threatens the sustainability of vineyards worldwide. Esca is caused by numerous wood-decay and wood-decay associated fungi, but its full etiology remains unclear due to the grapevine trunk disease complex, making effective control methods challenging.
