Summary: Preeclampsia is associated with increased cardiovascular risk for both mother and child. This study investigated the effects of preeclampsia on lipid metabolism, HDL composition, and function in mothers and neonates. Preeclampsia was linked to dyslipidemia in mothers, including high triglycerides and low HDL-cholesterol levels. Mothers with preeclampsia showed shifts in HDL subclasses and increased levels of HDL-associated apolipoprotein C-II. Neonates born to mothers with preeclampsia had increased total cholesterol levels and reduced HDL cholesterol efflux capacity. These findings suggest that preeclampsia affects both maternal and neonatal lipoprotein metabolism.

Summary: This study found that higher baseline serum cholesterol levels in TB patients were associated with lower risks of all-cause and infection-related mortality, as well as lower levels of inflammatory markers. Body mass index did not modify or confound this association.

Summary: This study investigated the effects of regular physical activity on two important functions of HDL, namely cholesterol reception and antioxidant capacity. The results showed that active individuals had higher HDL-C levels, better cholesterol transfer, and more HDL subfractions compared to inactive individuals. Age did not have a significant effect on these functions.

Summary: This study aims to investigate whether a histone deacetylase inhibitor, sodium butyrate (NaBu), can protect the porcine liver from deoxynivalenol (DON) exposure by modulating cholesterol metabolism. The results showed that NaBu effectively restored parameters associated with liver injury, cholesterol content, and key genes involved in the cholesterol biosynthesis pathway.

Summary: The study found that psoriasis patients had impaired HDL function at baseline compared to controls, but short-term and especially intermediate-term therapy with biologics markedly reduced HDL cholesterol efflux capacity and rendered HDL pro-inflammatory. However, it increased paraoxonase and lecithin-cholesterol acyltransferase activities. All biologics caused similar changes in HDL composition, subclass distribution and cholesterol efflux capacity.

Summary: Atherosclerosis is a disease characterized by increased oxidative stress, leading to modifications of proteins and lipids in the blood vessel wall. Myeloperoxidase (MPO), an enzyme mainly found in neutrophils and monocytes, plays a crucial role in this oxidative process. Research has shown that MPO interacts with lesion derived high-density lipoprotein (HDL) and modifies its components, leading to dysfunction of HDL. Understanding the impact of MPO-induced changes on the structure and function of HDL is important for the future use of HDL in diagnostics and therapy.

Summary: In this study, the characteristics of cognitive dysfunction in schizophrenia patients with metabolic syndrome (MS) were explored, and the effects of psychological intervention on MS and cognitive function changes in schizophrenia patients were investigated, providing a theoretical basis for early intervention of MS. Retrospective analysis of 159 schizophrenia patients divided them into two groups based on the presence of MS. The results showed that the cognitive impairment in the MS group was more severe compared to the non-MS group. Increasing psychological intervention effectively improved the therapeutic effect and cognitive function of schizophrenia patients. Early identification and intervention of MS is particularly important in the clinical treatment of schizophrenia.

Summary: Plants employ various adaptive strategies to respond to daylength variation, including adjustments in growth, photosynthesis, carbon utilization, and metabolic flux. Under short-day conditions, plants compensate for reduced CO2 fixation by enhancing photosynthetic rates and reducing respiration in the light, while also reducing the partitioning of glucose and increasing starch accumulation to sustain carbon availability during the longer night. Isotopic labeling results demonstrate substantial changes in the partitioning of amino acids and TCA cycle intermediates between rapidly and slowly turning over pools in response to different daylengths.

Summary: This study investigated the association between hepatic and metabolic factors and renal cancer risk. The results showed that high serum HDL-C levels reduced renal cancer risk, while hepatitis B virus antigen and chronic HBV infection increased its risk. In addition, BMI and alcohol consumption were also associated with renal cancer risk.

Summary: This study found an association between Metabolic syndrome and its components with the incidence of cholelithiasis, with a higher number of MetS components associated with an increased risk of cholelithiasis. Among MetS components, low HDL cholesterol level was found to be the most relevant factor for incident cholelithiasis.

Summary: For a given body mass index (BMI), both impaired metabolic health (MH) and reduced cardiorespiratory fitness (CRF) are independently associated with increased carotid intima-media thickness (cIMT) in obese subjects. Metabolically healthy obesity (MHO) has higher cIMT compared to metabolically healthy normal weight (MHNW) subjects, but this difference becomes statistically nonsignificant when cardiorespiratory fitness is taken into account. These results suggest that low CRF may explain part of the increased CVD risk observed in MHO compared with MHNW.

Summary: The study investigated the suitability of different emulsifiers in oil-in-water emulsions used as tissue analogs for MRI experiments. It was found that soy lecithin is the preferred emulsifier due to its high stabilizing ability and invisibility in MRI experiments. Additionally, lecithin can adjust relaxation times and ADC values of water, making it an alternative means for MRI experiments.

Summary: This study investigated the role of extracellular platelet nucleotide signaling in ischemic inflammatory response (IIR) and identified a cybernetic circle, including feedback loops, in the regulation of platelet function in IIR. The study confirmed the presence of different components and feedback loops in the cybernetic system and demonstrated the impact of platelet-neutrophil complex (PNC) formation on blood and inflamed tissue. The integration of extracellular nucleotide signaling, PNC formation, and tissue damage in IIR was described through this study.

Summary: Soy lecithin shows promise as a substance for constructing diffusion phantoms with tissue-like ADC values, covering the entire physiological range reported on biological tissue, with restricted diffusion of water molecules and nearly Gaussian diffusion characteristics. Adding agar allows for adjustment of T2 values to typical tissue values without affecting the soy lecithin-controlled ADC value.

Summary: This article presents raw and processed data related to the research conducted by Vega et al. (2022). The dataset provides additional insights into the experimental validation of a common carotid artery occlusion (CCAO) model with pretreatment of pertussis toxin (PTX). The data demonstrate the impact of different PTX concentrations on neurological severity measured by Bederson score following CCAO. Furthermore, the data indicate the protective effect of isoflurane on cerebral infarction and neurological deficits, as well as the consequences of PTX pretreatment on reperfusion after occlusion using time-of-flight magnetic resonance angiography.

Summary: This study demonstrates the feasibility of deep learning-based image segmentation for the assessment of adipose tissue and spatial distribution of visceral and subcutaneous fat in a large population-based cohort in Germany. The results show significant differences in fat distribution between genders and age/body mass index-related displacements. Deep learning-based image segmentation provides a robust and fast quantification of adipose tissue and assessment of its spatial distribution in large cohort studies.

Summary: We investigated the interaction between pancreatic preadipocytes (PPAs) and islets, as well as their crosstalk with fatty liver. Our findings showed that ECM components differed in PPAs from individuals with prediabetes and type 2 diabetes compared to those with normal glucose regulation. Additionally, the hepatokine fetuin-A/palmitate influenced ECM formation/degradation in PPAs and co-cultured islets, and enhanced monocyte migration, particularly in individuals with type 2 diabetes.
