Correlations between the peripheral coronary fat attenuation index based on computed tomography images, high-risk plaque and degree of coronary artery stenosis in patients with coronary atherosclerosis.

Background: Coronary artery disease can be quantified by measuring the fat attenuation index (FAI).

Objective: To explore the correlations between FAI, high-risk plaque and the degree of coronary artery stenosis.

Methods: The clinical data of patients with coronary atherosclerosis who underwent a coronary computed tomography (CT) angiography examination between July 2020 and June 2023 were selected for retrospective analysis.

Organocatalytic (/)-Selective Synthesis of 3-Vinylnaphthofurans via a Formal (3 + 2) Cycloaddition.

A formal (3 + 2) cycloaddition of 1,4-enediones with 2-naphthols was established under the catalysis of trifluoromethanesulfonic acid as an organocatalyst, leading to the efficient synthesis of structurally diverse 3-vinylnaphthofurans with high yields and excellent (/)-selectivities (up to 96% yield, all >20:1 /). This formal (3 + 2) cycloaddition involved a cascade reaction process, and the intramolecular hydrogen bond in the structure of 3-vinylnaphthofurans should play an important role in controlling the (/)-selectivity of the newly formed vinyl group. Moreover, this class of 3-vinylnaphthofurans was discovered to have an axial chirality.

Prenatal diagnosis of de novo isochromosome 4p with an unbalanced t(4;9) translocation in a fetus with congenital anomalies: A case report and literature review.

Objective: We present the first case of prenatally diagnosed isochromosome 4p with whole 4q arm translocating to chromosome 9p23 and review the literature.

Case Report: A 26-year-old woman underwent amniocentesis at 25 weeks of gestation because of an abnormal ultrasound examination. Routine chromosome analysis on cultured amniocytes showed a karyotype of 46,XX, ?idic(4)(q11),der(9)t(4;9)(q11;p23).

Identification of a Novel COL17A1 Compound Heterozygous Mutation in a Chinese Girl with Non-Herlitz Junctional Epidermolysis Bullosa.

Non-Herlitz junctional epidermolysis bullosa (JEB-nH), an autosomal recessive bullous genodermatosis, is characterized by generalized skin blistering from birth onward, dental anomalies, universal alopecia and nail dystrophy. The underlying defect is mutation of the COL17A1 gene encoding the type XVII collagen, resulting in losing structure for attachment of basal epithelial cells to the matrix. In present study, we described one case of congenitally affected female child aged 10 years, with skin blistering.
