AB  - Background: The pre-analytical (PA) phase is the most vulnerable phase of laboratory testing procedure, with critical procedures-collection, handling, sample transport, and time and temperature of sample storage. The aim of this study was to examine if different anticoagulants, storage conditions, and freeze-thaw cycles (FTCs) influence the concentrations of basic biochemical parameters. In parallel, the presence and the effect of sample microbiological contamination during routine laboratory work were examined.

Methods: Two plasma pools (EDTA, and sodium-fluoride/potassium oxalate plasma (NaF)) were stored at +4C˚/-20˚C. Total cholesterol (TC), glucose, triglycerides (TG), urea, total protein (TP), and albumin concentrations were measured using Ilab 300+. Sample microbiological contamination was determined by 16S rRNA sequence analysis. The experiment encompassed a 5 day-period: Day 1–fresh sample, Day 2–1st FTC, Day 3–2nd FTC, Day 4–3rd FTC, Day 5–4th FTC. The appearance of bacteria in two consecutive samples was the experiment's endpoint.

Results: During 4 FTCs there were no changes in plasma urea concentrations. Glucose was stable in EDTA+4˚C and NaF- 20˚C until the 3rd FTC (P=0.008, P=0.042, respectively). Changes in protein concentrations followed the zig-zag pattern. TG concentrations changed significantly in the EDTA-20˚C sample after 1st and 4th FTCs (P=0.022, P=0.010, respectively). In NaF samples no contamination was observed during 4 FTCs.

 

Conclusions: Urea and glucose concentrations were robust. Changes in lipid and protein concentrations after FTCs follow complex patterns. Bacterial growth was not observed in NaF plasma samples. This can promote NaF use in analytical procedures in which microbiological contamination affects the quality of analysis.
AB  - Uvod: Preanaliti~ka (PA) faza je slo`en proces koji ~ine:
prikupljanje, rukovanje, transport i skladi{tenje uzoraka, i
predstavlja najzna~ajniji izvor laboratorijskih gre{aka. Cilj
ovog istra`ivanja je bio da se ispita stabilnost osnovnih
biohemijskih parametara u zavisnosti od uslova skladi{tenja
uzoraka i broja ciklusa zamrzavanja-odmrzavanja (FTC).
Pored toga, ispitivano je prisustvo bakterijske kontaminacije
uzoraka tokom rutinskog laboratorijskog rada.
Metode: Dva »pool«-a plazme (etilendiaminotetrasir}etna
kiselina (EDTA) i natrijum-fluorid/kalijum oksalat (NaF)) su
skladi{tena na +4 ˚C/-20 ˚C. Koncentracije ukupnog
holesterola (TC), glukoze, triglicerida (TG), uree i albumina
su odre|ene kori{}enjem BioSystems reagenasa (holesterol
oksidaza/peroksidaza, glukoza oksidaza/peroksidaza,
glice rol fosfat oksidaza/peroksidaza, ureaza/salicilat, od-
nosno bromkrezol zeleno metodama, sukcesivno) na Ilab
300+ analizatoru. Bakterijska kontaminacija uzoraka je
potvr|ena 16S rRNA sekvencioniranjem. Eksperiment je
sproveden tokom 5 uzastopnih dana: 1. dan – sve` uzorak,
2. dan – 1. FTC, 3. dan –2. FTC, 4. dan – 3. FTC, 5. dan
– 4. FTC. Zavr{nu ta~ku eksperimenta predstavljala je
pojava bakterija u dva uzastopna uzorka.
Rezultati: Tokom 4 FTC koncentracije uree u plazmi se nisu
zna~ajno razlikovale. Koncentracija glukoze je bila stabilna
u EDTA +4 ˚C i NaF -20 ˚C do 3.FTC (P=0,008,
P=0,042, redom). Koncentracije TG su se zna~ajno pro-
menile u uzorku EDTA -20 ˚C nakon 1. i 4. FTC-a (P=0,022, P=0,010, redom). U uzorcima NaF plazme
nije do{lo do bakterijske kontaminacije tokom 4. FTC.
Zaklju~ak: Koncentracije uree i glukoze su bile stabilne
tokom trajanja eksperimenta. Promene u koncentracijama
lipida nakon FTC prate slo`ene obrasce. Rast bakterija nije
prime}en u uzorcima NaF plazme, te upotreba ovog anti-
koagulansa mo`e biti opravdana u analiti~kim proce -

AB  - A specific feature of dyslipidemia in pregnancy is increased high-density lipoprotein (HDL) cholesterol concentration, which is probably associated with maternal endothelium protection. However, preeclampsia is most often associated with low HDL cholesterol, and the mechanisms behind this change are scarcely explored. We aimed to investigate changes in HDL metabolism in risky pregnancies and those complicated by late-onset preeclampsia. We analyze cholesterol synthesis (cholesterol precursors: desmosterol, 7-dehydrocholesterol, and lathosterol) and absorption markers (phytosterols: campesterol and β-sitosterol) within HDL particles (NCSHDL), the activities of principal modulators of HDL cholesterol’s content, and major HDL functional proteins levels in mid and late pregnancy. On the basis of the pregnancy outcome, participants were classified into the risk group (RG) (70 women) and the preeclampsia group (PG) (20 women). HDL cholesterol was lower in PG in the second trimester compared to RG (p < 0.05) and followed by lower levels of cholesterol absorption markers (p < 0.001 for campesterolHDL and p < 0.05 for β-sitosterolHDL). Lowering of HDL cholesterol between trimesters in RG (p < 0.05) was accompanied by a decrease in HDL phytosterol content (p < 0.001), apolipoprotein A-I (apoA-I) concentration (p < 0.05), and paraoxonase 1 (PON1) (p < 0.001), lecithin–cholesterol acyltransferase (LCAT) (p < 0.05), and cholesterol ester transfer protein (CETP) activities (p < 0.05). These longitudinal changes were absent in PG. Development of late-onset preeclampsia is preceded by the appearance of lower HDL cholesterol and NCSHDL in the second trimester. We propose that reduced capacity for intestinal HDL synthesis, decreased LCAT activity, and impaired capacity for HDL-mediated cholesterol efflux could be the contributing mechanisms resulting in lower HDL cholesterol.

AB  - In order to understand the metabolic and immune potential of adiponectin in
colorectal cancer (CRC), attention is drawn to its receptors: adiponectin receptor 1
(ADIPOR1) and adiponectin receptor 2 (ADIPOR2). Gene set enrichment analysis (GSEA) of
datasets based on malignant tissue samples and peripheral blood monocytes (PBMs) was
used to explore mRNA fingerprints of different signaling pathways best associated with
ADIPOR1/ADIPOR2 gene expression levels. Transcriptomic datasets GSE44076 (1) and
GSE47756 (2) were downloaded from the NCBI Gene Expression Omnibus database. In the
GSE44076 dataset, three groups were formed: 98 colon tumor tissue and matched tumor-
adjacent mucosa samples and tissue samples from 50 healthy volunteers. The other set
(GSE47756) contained information on PBMs' gene signature in CRC, by forming two groups:
38 samples from healthy subjects and 55 CRC patients. GSEA analysis of the GSE44076
dataset implied that ADIPOR1 mRNA levels were in negative association with MTORC1 and
TNF-α NF-κB signaling pathways in tumor tissue. At the same time, ADIPOR2 was positively
associated with metabolic gene sets such as cholesterol homeostasis, glycolysis and PPAR
signaling. Quite opposite to the GSE44076 dataset, GSEA analysisis of GSE47756 revealed
that ADIPOR1 was a metabolically active receptor in PBMs of CRC patients. Surprisingly, the
TNF-α NF-κB signaling pathway gene sets were positively associated with ADIPOR1 mRNA
levels in monocytes of the cancer group. Different types of metabolic and immune regulation
achieved through ADIPOR1/ADIPOR2 in tumor and PBMs suggest possible novel therapeutic
targets in CRC.
AB  - Da bi se razumeo metabolički i imuni potencijal adiponektina u kolorektalnom
karcinomu (CRC), pažnja se mora obratiti i na njegove receptore: adiponektinski receptor 1
(ADIPOR1) i adiponektinski receptor 2 (ADIPOR2). Gene set enrichment analiza (GSEA) dva
skupa podataka, zasnovanih na uzorcima malignog tkiva i na monocitima periferne krvi
(PBM) je korišćena da bi se obezbedili genetski otisci različitih signalnih puteva koji su bili
najbolje povezani sa ekspresijom gena ADIPOR1/ADIPOR2. Skupovi transkriptomskih
podataka GSE44076 (1) i GSE47756 (2) su preuzeti iz NCBI Gene Expression Omnibus baze
podataka. U skupu podataka GSE44076 formirane su tri grupe: 98 uparenih uzoraka
tumorskog tkiva debelog creva i susedne mukoze i uzorci tkiva 50 zdravih dobrovoljaca.
Drugi set (GSE47756) je sadržao informacije o otisku gena PBM u CRC sa formiranim dvema
grupama: 38 uzoraka zdravih subjekata i 55 pacijenata sa CRC. GSEA analiza skupa podataka
GSE44076 je implicira da su nivoi iRNK ADIPOR1 negativno korelirali sa MTORC1 i TNF-α
NF-κB signalnim putevima u tumorskom tkivu. Istovremeno, ADIPOR2 je bio pozitivno
povezan sa skupovima gena metaboličkih puteva kao što su homeostaza holesterola,

abstract = "In order to understand the metabolic and immune potential of adiponectin in
colorectal cancer (CRC), attention is drawn to its receptors: adiponectin receptor 1
(ADIPOR1) and adiponectin receptor 2 (ADIPOR2). Gene set enrichment analysis (GSEA) of
datasets based on malignant tissue samples and peripheral blood monocytes (PBMs) was
used to explore mRNA fingerprints of different signaling pathways best associated with
ADIPOR1/ADIPOR2 gene expression levels. Transcriptomic datasets GSE44076 (1) and
GSE47756 (2) were downloaded from the NCBI Gene Expression Omnibus database. In the
GSE44076 dataset, three groups were formed: 98 colon tumor tissue and matched tumor-
adjacent mucosa samples and tissue samples from 50 healthy volunteers. The other set
(GSE47756) contained information on PBMs' gene signature in CRC, by forming two groups:
38 samples from healthy subjects and 55 CRC patients. GSEA analysis of the GSE44076
dataset implied that ADIPOR1 mRNA levels were in negative association with MTORC1 and
TNF-α NF-κB signaling pathways in tumor tissue. At the same time, ADIPOR2 was positively
associated with metabolic gene sets such as cholesterol homeostasis, glycolysis and PPAR
signaling. Quite opposite to the GSE44076 dataset, GSEA analysisis of GSE47756 revealed
that ADIPOR1 was a metabolically active receptor in PBMs of CRC patients. Surprisingly, the
TNF-α NF-κB signaling pathway gene sets were positively associated with ADIPOR1 mRNA
levels in monocytes of the cancer group. Different types of metabolic and immune regulation
achieved through ADIPOR1/ADIPOR2 in tumor and PBMs suggest possible novel therapeutic
targets in CRC., Da bi se razumeo metabolički i imuni potencijal adiponektina u kolorektalnom
karcinomu (CRC), pažnja se mora obratiti i na njegove receptore: adiponektinski receptor 1
(ADIPOR1) i adiponektinski receptor 2 (ADIPOR2). Gene set enrichment analiza (GSEA) dva
skupa podataka, zasnovanih na uzorcima malignog tkiva i na monocitima periferne krvi
(PBM) je korišćena da bi se obezbedili genetski otisci različitih signalnih puteva koji su bili
najbolje povezani sa ekspresijom gena ADIPOR1/ADIPOR2. Skupovi transkriptomskih
podataka GSE44076 (1) i GSE47756 (2) su preuzeti iz NCBI Gene Expression Omnibus baze
podataka. U skupu podataka GSE44076 formirane su tri grupe: 98 uparenih uzoraka
tumorskog tkiva debelog creva i susedne mukoze i uzorci tkiva 50 zdravih dobrovoljaca.
Drugi set (GSE47756) je sadržao informacije o otisku gena PBM u CRC sa formiranim dvema
grupama: 38 uzoraka zdravih subjekata i 55 pacijenata sa CRC. GSEA analiza skupa podataka
GSE44076 je implicira da su nivoi iRNK ADIPOR1 negativno korelirali sa MTORC1 i TNF-α
NF-κB signalnim putevima u tumorskom tkivu. Istovremeno, ADIPOR2 je bio pozitivno
povezan sa skupovima gena metaboličkih puteva kao što su homeostaza holesterola,
glikoliza i PPAR signalizacija. Nasuprot GSE44076 skupu podataka, GSEA analiza GSE47756
transkriptomskog seta je otkrila da je ADIPOR1 zapravo metabolički aktivan receptor u PBM
pacijenata sa CRC. Iznenađujuć e, setovi gena koji su se odnosili na signalni put TNF-α NF-κB
su bili pozitivno povezani sa nivoima iRNK ADIPOR1 u monocitima grupe sa karcinomom.

AB  - Adiponectin (ADIPOQ) as both a regulator of metabolic homeostasis and a protein involved in immune response might be of particular interest to contemporary laboratory medicine, especially in terms of minimally invasive diagnostics. The diverse roles of ADIPOQ with regard to the immune and metabolic aspects of colorectal carcinogenesis have been proposed. However, the expression of its receptors ADIPOR1 and ADIPOR2 is scarcely explored in peripheral blood mononuclear cells (PBMCs). Moreover, ADIPORs’ relationships with the immune response mediator TNF-α have not been previously investigated in the PBMCs of CRC patients. This study used both in silico and observational case–control analyses with the aim of exploring the association of ADIPOR gene expression and ADIPOQ single nucleotide polymorphisms (SNPs) with the inflammatory marker TNF-α and lipid status parameters in patients with CRC. Publicly available transcriptomic datasets (GSE47756, GSE44076) obtained from analyses of monocytes and CRC tissue samples were employed for the in silico evaluation of ADIPORs’ specific genetic traits. GSE47756 and GSE44076 datasets were processed with GSEA software to provide a genetic fingertip of different signaling pathways associated with ADIPORs’ mRNA levels. The case–control aspect of the study included the PBMC samples of 73 patients diagnosed with CRC and 80 healthy volunteers. The PCR method was carried out for the PBMC gene expression analysis (ADIPOR1, ADIPOR2, TNF-α mRNA levels) and for the subjects’ genotyping (ADIPOQ rs266729, ADIPOR1 rs7539542). GSEA showed significant associations of ADIPOR mRNA expression with gene sets related to metabolic and immune homeostasis in both datasets. The case–control study revealed the association of ADIPOR1 rs7539542 with reduced lipid status parameters in CRC. In addition, PBMC ADIPOR1 mRNA levels decreased in CRC (p < 0.001), whereas ADIPOR2 mRNA did not differ between the groups (p = 0.442). A reduction in PBMC TNF-α mRNA levels was noted in CRC (p < 0.05). Our results indicate that ADIPOR1 and ADIPOR2 play a significant role in the alteration of both metabolic and immune homeostasis during the progression of CRC. For the first time, ADIPOR1 is shown to be a specific receptor for mediating ADIPOQ’s effects in the PBMCs of CRC patients.

AB  - Background and Objectives: Diabetic foot (DF) development is driven by complex interactions of hyperglycemia, inflammation, and oxidative stress (OS). We aimed to investigate OS and inflammatory biomarkers in patients with DF and their potential to improve early diagnosis and management of DF. Materials and Methods: The prooxidant–antioxidant balance (PAB), superoxide dismutase (SOD), total oxidative status (TOS), total sulfhydryl groups (SHG), routine biochemical parameters, and complete blood count were determined in 42 patients with type-2 DM, of which 23 patients had DF, while 19 patients were without DF complications. The neutrophils-to-lymphocyte ratio (NLR) was evaluated as a biomarker of inflammation. Results: Patients with DF had significantly higher (p < 0.05) PAB levels (170 ± 33.9 U/L) compared to those without DF complications (142 ± 31.3 U/L). In addition, patients with DF had significantly reduced SOD activities (p < 0.01). NLR values were significantly higher in the DF group (median: 2.8; interquartile range: 2.0–4.3) than in the group without DF (median: 1.4; interquartile range: 1.4–2.1; p < 0.01). A positive correlation was found between the PAB and NLR index (r = 0.449; p < 0.05). The diagnostic accuracy of both PAB (AUC = 0.741; p < 0.01) and NLR (AUC = 0.760; p < 0.01) was estimated as acceptable. Conclusions: In conclusion, the development of DF is associated with enhanced OS and inflammation processes. PAB and NLR could be useful non-invasive biomarkers of DF development.

AB  - Metabolic disorders in pregnancy, particularly gestational diabetes mellitus (GDM), are associated with an increased risk for adverse pregnancy outcome and long-term cardiometabolic health of mother and child. This study analyzed changes of serum cholesterol synthesis and absorption markers during the course of high-risk pregnancies, with respect to the development of GDM. Possible associations of maternal lipid biomarkers with neonatal characteristics were also investigated. The study included 63 women with high risk for development of pregnancy complications. Size and proportions of small low-density (LDL) and high-density lipoprotein (HDL) particles were assessed across trimesters (T1–T3), as well as concentrations of cholesterol synthesis (lathosterol, desmosterol) and absorption markers (campesterol, β-sitosterol). During the study, 15 women developed GDM, while 48 had no complications (non-GDM). As compared to the non-GDM group, women with GDM had significantly higher triglycerides in each trimester, while having a lower HDL-C level in T3. In addition, they had significantly lower levels of β-sitosterol in T3 (p < 0.05). Cholesterol synthesis markers increased across trimesters in both groups. A decrease in serum β-sitosterol levels during the course of pregnancies affected by GDM was observed. The prevalence of small-sized HDL decreased in non-GDM, while in the GDM group remained unchanged across trimesters. Newborn’s size in the non-GDM group was significantly higher (p < 0.01) and inversely associated with proportions of both small, dense LDL and HDL particles (p < 0.05) in maternal plasma in T1. In conclusion, high-risk pregnancies affected by GDM are characterized by altered cholesterol absorption and HDL maturation. Advanced lipid testing may indicate disturbed lipid homeostasis in GDM.

abstract = "Metabolic disorders in pregnancy, particularly gestational diabetes mellitus (GDM), are associated with an increased risk for adverse pregnancy outcome and long-term cardiometabolic health of mother and child. This study analyzed changes of serum cholesterol synthesis and absorption markers during the course of high-risk pregnancies, with respect to the development of GDM. Possible associations of maternal lipid biomarkers with neonatal characteristics were also investigated. The study included 63 women with high risk for development of pregnancy complications. Size and proportions of small low-density (LDL) and high-density lipoprotein (HDL) particles were assessed across trimesters (T1–T3), as well as concentrations of cholesterol synthesis (lathosterol, desmosterol) and absorption markers (campesterol, β-sitosterol). During the study, 15 women developed GDM, while 48 had no complications (non-GDM). As compared to the non-GDM group, women with GDM had significantly higher triglycerides in each trimester, while having a lower HDL-C level in T3. In addition, they had significantly lower levels of β-sitosterol in T3 (p < 0.05). Cholesterol synthesis markers increased across trimesters in both groups. A decrease in serum β-sitosterol levels during the course of pregnancies affected by GDM was observed. The prevalence of small-sized HDL decreased in non-GDM, while in the GDM group remained unchanged across trimesters. Newborn’s size in the non-GDM group was significantly higher (p < 0.01) and inversely associated with proportions of both small, dense LDL and HDL particles (p < 0.05) in maternal plasma in T1.

AB  - Introduction  The aim of this study was to investigate lipoprotein particle distributions and the likelihood of achieving cholesterol homeostasis in the remission phase of nephrotic syndrome (NS) in paediatric patients. We hypothesized that lipoprotein particle distributions moved toward less atherogenic profile and that cholesterol homeostasis was achieved. Materials and methods  Thirty-three children, 2 to 9 years old with NS were recruited. Blood sampling took place both in the acute phase and during remission. Serum low-density lipoprotein particles (LDL) and high-density lipoprotein particles (HDL) were separated using non-denaturing polyacrylamide gradient gel (3-31%) electrophoresis. Serum non-cholesterols sterols (NCSs), desmosterol, lathosterol, 7-dehydrocholesterol (7-DHC), campesterol and β-sitosterol were measured by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Results  All patients had desirable serum HDL cholesterol concentrations during remission. The dominant lipoprotein diameters and LDL subclass distribution did not change significantly during follow-up. In contrast, HDL lipoprotein particle distribution shifted towards larger particles. The absolute concentration of desmosterol was significantly lower during remission (P = 0.023). β-sitosterol concentration markedly increased during remission (P = 0.005). Desmosterol/β-sitosterol (P < 0.001) and 7-DHC/β-sitosterol (P = 0.005) ratios significantly declined during disease remission. Conclusions  Favourable changes in the serum lipid profiles, HDL particle subclass distribution and cholesterol metabolism in paediatric patients with NS during remission took place. For the first time, we found that cholesterol homeostasis changed in favour of increased cholesterol absorption during disease remission. Nevertheless, complete cholesterol homeostasis was not achieved during disease remission.

AB  - Colorectal cancer (CRC) is a highly prevalent malignancy. Previous studies suggested that cholesterol might play a signficant role in malignant transformation and proliferation. Non-cholesterol sterols (NCS), which are transported by serum lipoproteins alongside cholesterol, are regarded as cholesterol synthesis and absorption markers. Quantification of NCS in serum and HDL fraction (NCSHDL), could provide a better insight into the cholesterol metabolism. The aim of this study was to examine the status of cholesterol synthesis and cholesterol absorption markers in serum and HDL fraction and explore their interrelation in CRC patients. Current study was designed as observational, case-control study. The study included 73 CRC patients and 95 healthy subjects. NCS and NCSHDL concentrations were determined by HPLC-MS/MS. Based on NCS and NCSHDL concentrations, different cholesterol homeostasis indices were calculated. Patients had significantly lower NCS (P<0.001) and NCSHDL concentrations (P<0.001 for desmosterolHDL; P<0.05 for lathosterolHDL, P=0.001 for campesterolHDL, P<0.001 for β-sitosterolHDL). NCSHDL/NCS (P<0.005 for desmosterolHDL/desmosterol; P<0.05 for lathosterolHDL/lathosterol; P<0.001 for both β-sitosterolHDL/β-sitosterol and campesterolHDL/campesterol) and synthesis to absorption ratio (CSI/CAI) (P<0.005) were increased in CRC patients. Additionally, low serum concentrations of desmosterol (P<0.001; OR=0.329; 95%CI (0.199–0.542)) and campesterol (P<0.001; OR=0.540; 95%CI (0.424–0.687)) were independent predictors of CRC presence. Our data suggest that cholesterol homeostasis in CRC is shifted towards increased synthesis. Relative abundance of NCS in HDL particles is increased, suggesting the possible overproduction of cholesterol precursors in peripheral tissues.

AB  - Despite significant progress in improving pregnancy outcomes in recent decades,
predicting the risk and treatment of preeclampsia are still major challenges in clinical
practice (1). The aim of this study was to examine non-routine biomarkers in preeclampsia
risk assessment. The study involved 90 women with high-risk pregnancies, 20 of whom
developed preeclampsia by the end of pregnancy. Biochemical parameters were determined
between the 12th and 13 th weeks of gestation. The results of the study showed that women
who later developed preeclampsia had higher concentrations of lathosterol, cholesterol
synthesis marker (p <0.05), inflammatory proteins - monocyte chemoattractant protein-1
(MCP-1), and resistin (p <0.01, both), as well as paraoxonase-1 (PON1) activity (p <0.05).
Binary logistic regression analysis showed that higher concentrations of lathosterol, MCP-1,
resistin, and PON-1 were associated with preeclampsia development. To determine whether
the parameters significant in univariate analysis, are independent predictors of
preeclampsia, we applied multivariate regression analysis. Clinical markers commonly used
in risk assessment (maternal age and body mass index, mean arterial pressure, and uterine
blood flow), lathosterol, MCP-1, resistin, and PON-1 were included in the model. MCP-1 and
resistin stood out as significant independent predictors of preeclampsia. The diagnostic
accuracy of the investigated model was excellent (AUC=0.859). The study results indicated
the importance of a multi-marker approach in risk assessment for preeclampsia
development.

AB  - Insulin resistance, hyperlipidemia, oxidative stress and low-grade inflammation are
mechanisms underlying endothelial dysfunction and atherosclerosis development in non-
pregnant state, but in pregnancy they are adaptive mechanisms responsible for fetal
development without health risks for mothers. A special feature of lipids profile in pregnancy
is increase in high density lipoprotein (HDL) cholesterol concentration. Protective role of
HDL particles resides on its complex composition that goes beyond its cholesterol
concentration and exhibits vasodilatory, antioxidant, anti-inflammatory and
antithrombogenic effects. Even the importance of HDL functionality in pathogenesis of
cardiovascular disease has been investigated and confirmed its role in persevering metabolic

outcome" investigate the pattern of HDL particle distribution and functionality (HDL-ome)
with different pregnancy outcomes. With the sophisticated analytical methods we determine
HDL-ome in uncomplicated and high-risk pregnancies. We mark the HDL-ome component
with a different pattern of change during high-risk pregnancies and test their potential for
pregnancy complications risk assessment. In this this research we investigate molecular
mechanisms crucial for HDL remodelling during pregnancy and possible associations
between maternal metabolic health during pregnancy and maternal and child health in the
future. Such comprehensive approach will provide a better insight into HDL role in maternal
metabolic health during pregnancy and will open a door for further research in this area.

AB  - Adrenal incidentalomas are unexpectedly identified adrenal masses without prior suspicion
of the existence of adrenal disease. The majority of adrenal incidentalomas are benign adrenal
adenomas (80–90%), and they are non-functioning adrenocortical adenomas in more than 70% of
cases. Mild hypercortisolemia is the most common finding in hormonally active adrenal
incidentalomas. It is defined as autonomous cortisol secretion in up to 15% of patients. Despite a
lot of research that anticipated higher cardiometabolic risk in patients with autonomous cortisol
secretion, there is still no clear consensus on biochemical criteria for an autonomous cortisol
secretion diagnosis in patients with adrenal incidentalomas. This review delineates the advantages
and limitations of different laboratory tests recommended for the diagnosis of autonomous
cortisol secretion in adrenal incidentalomas.

AB  - Exposure to lead (Pb) is still rising concern worldwide, having in mind that even low-dose exposure can induce various harmful effects. Thus, in-depth knowledge of the targets of Pb toxicity and corresponding mechanisms is essential. In the presented study, the six groups (male Wistar rats, n = 6) received 0.1; 0.5; 1; 3; 7; 15 mg Pb/kg body weight/day for 28 days, each day by oral gavage, while the control group received distilled water only. All animals were sacrificed 24 h after the treatment, and blood was collected for the analysis of hematological, biochemical, oxidative status and essential elements levels. An external and internal dose-response relationship was performed using PROASTweb 70.1 software. The results showed that low doses of Pb affect hematological parameters and lipid profile after 28 days. The possible mechanisms at examined Pb dose levels were a decrease in SOD, O2•􀀀 and Cu and an increase in Zn levels. The dose-dependent nature of changes in cholesterol, HDL cholesterol, O2.-, SOD, AOPP in serum and hemoglobin, Fe, Zn, Cu in blood were obtained in this study. The most sensitive parameters that were alerted are Cu blood levels (BMDL5: 1.4 ng/kg b.w./day) and SOD activity (BMDL5: 0.5 μg/kg b.w./day). The presented results provide information that may be useful in further assessing the health risks of low-level Pb exposure.

AB  - Introduction The link between preeclampsia and dyslipidemia has been established. Even though lipid profile parameters have been intensively investigated in the pathology of preeclampsia, their accurate molecular mechanisms of action have not been fully decoded. Objectives We aimed to identify the specifics of cholesterol metabolism in women affected by late‑onset preeclampsia and single out potential biomarkers associated with late‑onset syndrome. Patient s and methods A total of 90 pregnant women with a priori risk for preeclampsia were monitored at 4 time points during gestation and, based on the outcome of pregnancy, they were classified into the high‑risk group (70 women) and the preeclampsia group (20 women). Cholesterol metabolic profiling was done using liquid chromatography‑tandem mass spectrometry. Result s The only significant change in the preeclampsia group was an increase in the lathosterol level (P = 0.001). The first‑trimester lathosterol level was higher in the preeclampsia group compared with the high‑risk group (P = 0.02). Further, in the preeclampsia group, positive correlations were found between desmosterol and β‑sitosterol (ρ = 0.474; P = 0.03) in the third trimester, desmosterol and campesterol changes between the second and the first (ρ = 0.546; P = 0.02), and the third and first trimesters (ρ = 0.754; P <0.001), as well as between the desmosterol and β‑sitosterol differences between the third and first trimesters (ρ = 0.568; P = 0.01). No similar correlations were found in the high‑risk group. Conclusions Late‑onset preeclampsia could be associated with an altered lipid profile. By studying the quantitative metabolic signatures of cholesterol, we might assume that both cholesterol synthesis and absorption are increased, that is, there is an imbalance in the cholesterol homeostasis regulation in women affected by the disease.

AB  - Preeclampsia (PE) is a leading cause of maternal and neonatal morbidity and mortality worldwide. Defects in trophoblast invasion, differentiation of extravillous trophoblasts and spiral artery remodeling are key factors in PE development. Currently there are no predictive biomarkers clinically available for PE. Recent technological advancements empowered transcriptome exploration and led to the discovery of numerous non-coding RNA species of which microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are the most investigated. They are implicated in the regulation of numerous cellular functions, and as such are being extensively explored as potential biomarkers for various diseases. Altered expression of numerous lncRNAs and miRNAs in placenta has been related to pathophysiological processes that occur in preeclampsia. In the following text we offer summary of the latest knowledge of the molecular mechanism by which lnRNAs and miRNAs (focusing on the chromosome 19 miRNA cluster (C19MC)) contribute to pathophysiology of PE development and their potential utility as biomarkers of PE, with special focus on sample selection and techniques for the quantification of lncRNAs and miRNAs in maternal circulation.
