Background: Lipids are key modulators in the pathogenesis of Alzheimer's disease (AD). Dysregulation of lipid homeostasis may disrupt the blood brain barrier, alter myelination, disturb cellular signaling and cause abnormal processing of the amyloid precursor protein. The purpose of this scoping review was to evaluate fatty acid supplementation in patients with AD.

Uncertainty remains regarding the role of diet in colorectal cancer development. We examined associations of 97 dietary factors with colorectal cancer risk in 542,778 Million Women Study participants (12,251 incident cases over 16.6 years), and conducted a targeted genetic analysis in the ColoRectal Transdisciplinary Study, Colon Cancer Family Registry, and Genetics and Epidemiology of Colorectal Cancer Consortium (GECCO).

5-Enolpyruvylshikimate-3-phosphate synthase (EPSPS) catalyzes the conversion of 5-enolpyruvate (PEP) and shikimic acid phosphate (S3P) to 5-enolpyruvylshikimic acid-3-phosphate (EPSP), releasing inorganic phosphate. This reaction is the sixth step of the shikimate pathway, which is a metabolic pathway used by microorganisms and plants for the biosynthesis of aromatic amino acids and folates but not in mammals. In the present study, the detailed reaction mechanism of EPSPS from Nicotiana tabacum (NtEPSPS) is revealed by quantum chemical calculations with the cluster approach.

The bovine conceptus elongates near Day 16 of development and releases interferon-tau (IFNT), disrupting the endometrial luteolytic mechanism to sustain luteal P4 and pregnancy. Conceptus factors other than IFNT modify local endometrial activities to support pregnancy; however, the microenvironment is largely uncharacterized. We utilized a bovine conceptus-endometrial culture system to elucidate the microenvironment in the form of RNA and protein.

Methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) polymorphisms are known risk factors for vascular diseases due to the impact on folate metabolism dysfunction and homocysteine (Hcy) accumulation. This study aimed to investigate the association between folate metabolism risk and hemorrhagic risk in moyamoya disease (MMD). In this prospective study, we enrolled 350 MMD patients with complete genotype data for MTHFR and MTRR.
