By using 237 verified cases of diffuse carcinoma and benign diseases of the stomach as an example, the authors assess the capacities of routine transabdominal ultrasound study (USS) of the stomach in the diagnosis of tumors and present their modification of the procedure facilitating the imaging of problem areas. In the authors' opinion, the symptoms of thickening of the wall of the stomach and abnormalities in its normal five-layered structure indicate diffuse gastric carcinoma. The authors consider USS to be a supplement to the basic diagnostic techniques--X-ray study and gastroscopy.

Background: Therapeutic antibodies for the treatment of neurological disease show great potential, but their applications are rather limited due to limited brain exposure. The most well-studied approach to enhance brain influx of protein therapeutics, is receptor-mediated transcytosis (RMT) by targeting nutrient receptors to shuttle protein therapeutics over the blood-brain barrier (BBB) along with their endogenous cargos. While higher brain exposure is achieved with RMT, the timeframe is short due to rather fast brain clearance.

Background: Optical spectral transmission (OST) is a modern diagnostic method capable of quantifying inflammation in the finger and wrist joints of arthritis patients by assessing the blood-specific absorption of light transmitted through a tissue. The diagnostic performance of this modality has not been adequately examined and data regarding OST associations with magnetic resonance imaging (MRI) are limited. Aim of this study was therefore to investigate the performance of OST in assessing joint inflammation as compared to MRI in patients with inflammatory arthritis (IA).

Ultrasound Diagnosis Department, Maternal and Child Health Hospital of Hubei Province, Wuhan, 430070, China.
Background: The clinical manifestations of PI4KA-related disorders are characterized by considerable variability, predominantly featuring neurological impairments, gastrointestinal symptoms, and a combined immunodeficiency. The aim of this study was to delineate the novel spectrum of PI4KA variants detected prenatally and to assess their influence on fetal development.
Methods: A thorough fetal ultrasound screening was conducted, supplemented by both antenatal and post-abortion magnetic resonance imaging (MRI) studies.

Department of Intensive Care Medicine, Army Medical Center of PLA, No. 10 Changjiang Road, Yuzhong District, Chongqing, 400010, People's Republic of China.
Background: Pregnancy-associated atypical hemolytic uremic syndrome (aHUS) is a form of thrombotic microangiopathy (TMA) caused by uncontrolled activation of the complement system during pregnancy or the postpartum period. In the intensive care unit, aHUS must be differentiated from sepsis-related multiple organ dysfunction, thrombotic thrombocytopenic purpura (TTP), hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. Early recognition of aHUS is critical for effective treatment and improved prognosis.
