Objective: To investigate the relationship between lipid accumulation index and cerebral hemodynamic integral value in 3264 people undergoing physical examination, so as to analyze the correlation between different lipid accumulation product index (LAP) levels and stroke risk factors.
Methods: This cross-sectional study was conducted from January to December 2019 on 3264 adults at the age of 19 to 85 living in Urumqi, Xinjiang. The stroke related risk factors were evaluated by the questionnaire survey. The enrolled subjects were divided into Q1 group (n = 817), Q2 group (n = 815), Q3 group (n = 816) and Q4 group (n = 816) according to the quartile site at a low-to-high-score manner.
Results: The proportion of males was significantly higher than that of females in Q2, Q3, and Q4 groups. The proportion of middle-aged people and the elderly in Q2, Q3, and Q4 groups was significantly higher than that of youths (P < .05). The proportion of patients with history of hypertension, hyperlipidemia, physical inactivity, and smoking, and the levels of systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, high-density cholesterol, low-density cholesterol, triglyceride, body mass index, waist circumference increased with the increase of LAP level in different groups (P < .05). On both sides of the cerebral hemodynamic integral value (CVHI) index, Vmean, Vmax, Vmin showed a decreasing trend whereas peripheral resistance, pulse velocity, Zcv, dynamic resistance, critical pressure level, difference between diastolic and critical pressure showed an increase trend with the increase of LAP level. The normal rate of CVHI in 4 groups (>75 points) was 97.4%, 89.7%, 87.0, and 80.8%, respectively, showing a decreasing trend. Logistic regression results showed that the higher the LAP, the higher the abnormal risk of CVHI.
Conclusion: There is a positive correlation between LAP and CVHI, the higher the LAP, the higher the risk of CVHI abnormality, which should be concerned seriously.

Childhood obesity increases the risk of developing metabolic diseases in adulthood, since environmental stimuli during critical windows of development can impact on adult metabolic health. Studies demonstrating the effect of prepubertal diet on adult metabolic disease risk are still limited. We hypothesized that a prepubertal control diet (CD) protects the adult metabolic phenotype from diet-induced obesity (DIO), while a high-fat diet (HFD) would predispose to adult metabolic alterations.

The onset and development of Alzheimer's disease is linked to the accumulation of pathological aggregates formed from the normally monomeric amyloid-β peptide within the central nervous system. These Aβ aggregates are increasingly successfully targeted with clinical therapies at later stages of the disease, but the fundamental molecular steps in early stage disease that trigger the initial nucleation event leading to the conversion of monomeric Aβ peptide into pathological aggregates remain unknown. Here, we show that the Aβ peptide can form biomolecular condensates on lipid bilayers both in molecular assays and in living cells.

Actinobacteria belonging to Mycobacterium and Rhodococcus genera are able to synthesize and intracellularly accumulate variable amounts of triacylglycerols (TAG) in the form of lipid droplets (LDs). The lipid storage capacity of LDs in cells is controlled by the balance between lipogenesis and lipolysis. The growth of LDs in bacterial cells may be directly promoted by TAG biosynthesis, whereas TAG degradation might result in the reduction of LD sizes and lipid storage capacity.

Acute myocardial infarction (AMI) is associated with well-established metabolic risk factors, especially hyperlipidemia and obesity. Myocardial ischemia-reperfusion injury (mIRI) significantly offsets the therapeutic efficacy of revascularization. Previous studies indicated that disrupted lipid homeostasis can lead to lipid peroxidation damage and inflammation, yet the underlying mechanisms remain unclear.

α-Synuclein (αS) is a 140 amino-acid neuronal protein highly enriched in presynaptic nerve terminals. Its progressive accumulation in Lewy bodies and neurites is the hallmark of Parkinson's disease (PD). A growing number of studies highlights a critical interplay between lipid metabolism and αS biology.
