Minimal Symptoms From a 7-Month Retained Guidewire Following Acute Non-Tunneled Hemodialysis Catheter Insertion: A Case Report. [PDF]

Clin Case Rep
ABSTRACT Central venous catheterization (CVC), commonly used for hemodialysis due to its rapid access and immediate utility, carries risks—including the rare complication of guidewire retention. While typically identified early, retained guidewires can occasionally go unnoticed and migrate, leading to delayed and unexpected symptoms.

Single-Crystal-to-Single-Crystal Transformation in a Copper(II) Complex: Structural and Spectroscopic Insights into Methanol Elimination and Hydrogen Bond Network Formation. [PDF]

ChemistryOpen
A methanol‐ligated copper(II) complex undergoes a single‐crystal‐to‐single‐crystal transformation upon solvent loss, retaining crystallinity while reorganizing its coordination geometry and hydrogen‐bonding network. This study investigates the single‐crystal‐to‐single‐crystal (SCSC) transformations of a copper(II) complex, [Cu(L1)2(acac)2]·2CH3OH (1 ...

Biostratigraphy and Microfacies of Qom Formation in Urumieh – Dokhtar Zone, Iran [PDF]

International Journal of Engineering and Technology, 2018
In order to determine the accurate paleoenvironmental conditions of Qom Formation, one stratigraphic section was studied in the Urumieh-Dokhtar Zone (West of Ashtian). 60 thin sections of the Qom Formation, 71 m thick, were prepared and the distribution of benthic foraminifera was analyzed.

Public Health Implications of Latent Toxoplasmosis and Its Association With Type 2 Diabetes: A Case-Control Study in Qazvin, North-Western Iran. [PDF]

Health Sci Rep
ABSTRACT Introduction Toxoplasma gondii is a worldwide‐distributed zoonotic parasite, causing latent infections in humans. Increasing evidence has suggested a possible link between toxoplasmosis and diabetes mellitus (DM), though data from Iran are limited. This study was conducted to determine the seroprevalence of latent T.

Genesis of Tozlou Pb-Zn Occurrence (South of Zanjan): Evidence from Geology, Mineralization, and Geochemistry

Journal of Economic Geology, 2023
Tozlou Pb-Zn mineralization, ~250-300m long, and ~50m thick, is hosted by limestone units of the Qom Formation. The main mineralization zone occurred as vein-veinlets and vug infill textures, where mineralization is observed as Pb-Zn-bearing barite veins
