Annual biological variation and personalized reference intervals of 8 serum liver enzymes and 3 noninvasive tests in fatty liver patients.

Background: The liver function tests and noninvasive tests (NITs) play important roles in the follow-up and monitoring of fatty liver disease (FLD). Our aim is to establish annual biological variation (BV) and personalized reference intervals (prRIs) of liver function tests for the first time in order to accurately assess the status and progress of FLD.

Methods: 67 fatty liver patients who participated in regular physical examination once a year for six consecutive years, were enrolled.

Classification of CT scan and X-ray dataset based on deep learning and particle swarm optimization.

In 2019, the novel coronavirus swept the world, exposing the monitoring and early warning problems of the medical system. Computer-aided diagnosis models based on deep learning have good universality and can well alleviate these problems. However, traditional image processing methods may lead to high false positive rates, which is unacceptable in disease monitoring and early warning.

MiR-423 Coding Region Genetic Polymorphism rs8067576 May Associate With the Risk of Developing Recurrent Spontaneous Abortion: A Case-Control Study in a Chinese Han Population.

Background: Our previous study has identified an association of a single nucleotide polymorphism (SNP) in the miR-423 gene with recurrent spontaneous abortion (RSA). The presence of additional RSA-linked SNPs in the miR-423 gene remains unclear.

Methods: We evaluated polymorphisms in the coding region of miR-423 in Han Chinese women with unexplained RSA (URSA).

Malnutrition exacerbating neuropsychiatric symptoms on the Alzheimer's continuum is relevant to the cAMP signaling pathway: Human and mouse studies.

Introduction: Malnutrition correlates with neuropsychiatric symptoms (NPSs) in Alzheimer's disease (AD); however, the potential mechanism underlying this association remains unclear.

Methods: Baseline and longitudinal associations of nutritional status with NPSs were analyzed in 374 patients on the AD continuum and 61 healthy controls. Serum biomarkers, behavioral tests, cerebral neurotransmitters, and differentially gene expression were evaluated in standard and malnourished diet-fed transgenic APPswe/PSEN1dE9 (APP/PS1) mice.

Dimerization and dynamics of angiotensin-I converting enzyme revealed by cryoEM and MD simulations.

Angiotensin-I converting enzyme (ACE) regulates the levels of disparate bioactive peptides, notably converting angiotensin-I to angiotensin-II and degrading amyloid beta. ACE is a heavily glycosylated dimer, containing 4 analogous catalytic sites, and exists in membrane bound and soluble (sACE) forms. ACE inhibition is a frontline, FDA-approved, therapy for cardiovascular diseases yet is associated with significant side effects, including higher rates of lung cancer.
