The authors present the results of an experimental study of pharmacokinetics of a new Soviet drug 99 mTc-technephyte for scintigraphy of the liver and spleen. The results of biological distribution of the agent in rat, scintigrams of the liver and spleen in rabbits and dogs have shown a high accumulation of 99 mTc-technephyte in the liver (up to 90%). The agent is prepared within one stage from a kit of reagents and 99m-sodium pertechnetate obtained using a generator.

Prenatal diagnosis of mucopolysaccharidosis type I on hepatosplenomegaly and coarse features: a case-report.

Background: Mucopolysaccharidosis type I (MPS I - IDUA gene) is a rare autosomal recessive lysosomal storage disorder. Clinical symptoms, including visceral overload, are progressive and typically begin postnatally. Descriptions of hepatosplenomegaly associated with lysosomal pathology are uncommon during the prenatal period.

Additionally, 2D CT images obtained from different angles (such as sagittal, coronal, and transverse planes) increase the diversity of liver morphology and the complexity of segmentation. To address these issues, this paper proposes a Detail Enhanced Convolution (DE Conv) to improve liver feature learning and thereby enhance liver segmentation performance.

Importance: Hemochromatosis is rare in domestic animals, and iron-induced myopathy has not been reported in veterinary medicine. This case is the first report of iron-overload myopathy owing to hemochromatosis in a dog.
Case Presentation: A 9-year-old spayed female Donggyeong dog presented with severe forelimb lameness.
Pharmacokinetics, bioavailability, and tissue distribution of MRTX1133 in rats using UHPLC-MS/MS.

Introduction: MRTX1133 is a selective and reversible small molecule inhibitor of KRAS (G12D), which significantly delays the progression of solid tumors. However, no study on the absorption, distribution, and excretion of MRTX1133.
Methods: A fast ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry method was developed for the determination of MRTX1133 in rat plasma, tissue homogenate, and urine.
An Emerging Toolkit of Ho Sensitized Lanthanide Nanocrystals with NIR-II Excitation and Emission for Bioimaging.

Optical imaging in the second near-infrared window (NIR-II, 1000-1700 nm) holds great promise for biomedical detection due to reduced tissue scattering and autofluorescence. However, the rational design of NIR-II probes with superior excitation wavelengths to balance the effects of tissue scattering and water absorption remains a great challenge. To address this issue, here we developed a series of Ho-sensitized lanthanide (Ln) nanocrystals (NaYF: Ho, Ln@NaYF) excited at 1143 nm, featuring tunable emissions ranging from 1000 to 2200 nm for bioimaging.
