AB  - Appetite regulation in the hypothalamus is dependent on
hormonal signals from the periphery, such as insulin and
leptin, and can be modulated by both sugar-rich diet and
stress. Our aim was to explore the effects of 9-week feeding
with 20% fructose solution combined with 4-week
chronic unpredictable stress, on appetite-regulating neuropeptides
and modulatory role of leptin and insulin signalling
in the hypothalamus of male Wistar rats. Energy
intake, body mass and adiposity, as well as circulatory
leptin and insulin concentrations were assessed. Hypothalamic
insulin signalling was analysed at the level of glucose
transporters, as well as at the protein level and phosphorylation
of insulin receptor, insulin receptor supstrate-1, Akt
and ERK. Phosphorylation of AMP-activated protein kinase
(AMPK), level of protein tyrosine phosphatase 1B (PTP1B)
and expression of leptin receptor (ObRb) and suppressor of
cytokine signalling 3 (SOCS3) were also analysed, together
with the expression of orexigenic agouti-related protein
(AgRP) and anorexigenic proopiomelanocortin (POMC) neuropeptides.
The results revealed that stress decreased body
mass and adiposity, blood leptin level and expression of
ObRb, SOCS3 and POMC, while combination with fructose
diet led to marked increase of AgRP, associated with AMPK
phosphorylation despite increased plasma insulin. Reduced
Akt, enhanced ERK activity and elevated PTP1B were also
observed in the hypothalamus of these animals. In conclusion,
our results showed that joint effects of fructose diet
and stress are more deleterious than the separate ones,
since inappropriate appetite control in the hypothalamus
may provide a setting for the disturbed energy homeostasis
in the long run.

AB  - Sepsis is a life-threatening condition caused by the dysregulated and overwhelming
response to infection, accompanied by an exaggerated pro-inflammatory state and lipid metabolism
disturbance leading to sequential organ failure. Meldonium is an anti-ischemic and anti-inflammatory
agent which negatively interferes with lipid metabolism by shifting energy production from fatty
acid oxidation to glycolysis, as a less oxygen-demanding pathway. Thus, we investigated the effects
of a four-week meldonium pre-treatment on faecal-induced sepsis in Sprague-Dawley male rats.
Surprisingly, under septic conditions, meldonium increased animal mortality rate compared with
the meldonium non-treated group. However, analysis of the tissue oxidative status did not provide
support for the detrimental effects of meldonium, nor did the analysis of the tissue inflammatory
status showing anti-inflammatory, anti-apoptotic, and anti-necrotic effects of meldonium. After
performing tissue lipidomic analysis, we concluded that the potential cause of the meldonium
harmful effect is to be found in the overall decreased lipid metabolism. The present study underlines
the importance of uninterrupted energy production in sepsis, closely drawing attention to the possible
harmful effects of lipid-mobilization impairment caused by certain therapeutics. This could lead to
the much-needed revision of the existing guidelines in the clinical treatment of sepsis while paving
the way for discovering new therapeutic approaches.

AB  - Background: Sepsis is a life-threatening condition caused by the dysregulated and overwhelming response to infection, accompanied by exaggerated pro-inflammatory state and lipid metabolism disturbance leading to sequential organ failure.1, 2 Meldonium is an anti-ischemic and anti-inflammatory agent, clinically used to treat myocardial ischemia.3 By shifting energy production from fatty acid oxidation to glycolysis, as an oxygen less consuming pathway, meldonium interferes negatively with lipid metabolism. 
Methods: Thus, we investigated the effects of a 4-week meldonium pre-treatment in 300 mg/kg b.m./day dosage on the course of the sepsis induced by a single intraperitoneal injection of faeces (0.5 g faeces/1 mL saline/100 g b.m.)in Sprague-Dawley male rats. The degree of the heart injury was evaluated by measuring tissue pro-apoptotic Bax and anti-apoptotic Bcl-2 ratio, tissue level of the necrotic marker - high mobility group box 1 protein level (HMGB1), together with the heart histology analysis. Sepsis-associated heart inflammation
was assessed by measuring level of an activated form of NF-kB p65 (phospho-NF-κB p65).
Results: In the heart whole homogenates of the septic group of animals (S) HMGB1 level increased 1.7-fold, in comparison to control rats, while meldonium reduced sepsis-induced increase by 18 % (M+S). The underlying mechanism of the proinflammatory action of HMGB1 includes activation of NF-κB signalling
pathways tissue, so the increased HMGB1 level was followed by a 1.4-fold increase of p-NF-κB p65 in the heart of the S group of rats and a 19 % decreased in the heart of M+S group. The apoptotic marker Bax/Bcl-2 ratio changed in the same manner: 1.4-fold increase in the heart of animals from the S group and a 32 % decrease in the heart of the M+S group. On the other hand, heart histology analysis shows that meldonium worsened the heart histological score, causing the severe and diffuse interstitial mononuclear infiltration along with a greater loss of myocytes and myofibrillar contraction band necrosis. The heart lipidomic analysis suggests that meldonium exhibits potentially harmful effects under septic condition due to the lipid-mobilization impairment.
Conclusion: Meldonium exerted anti-inflammatory, anti-apoptotic, and anti- necrotic effects, while it worsened the septic rat heart histology.

pathways tissue, so the increased HMGB1 level was followed by a 1.4-fold increase of p-NF-κB p65 in the heart of the S group of rats and a 19 % decreased in the heart of M+S group. The apoptotic marker Bax/Bcl-2 ratio changed in the same manner: 1.4-fold increase in the heart of animals from the S group and a 32 % decrease in the heart of the M+S group. On the other hand, heart histology analysis shows that meldonium worsened the heart histological score, causing the severe and diffuse interstitial mononuclear infiltration along with a greater loss of myocytes and myofibrillar contraction band necrosis. The heart lipidomic analysis suggests that meldonium exhibits potentially harmful effects under septic condition due to the lipid-mobilization impairment.
Conclusion: Meldonium exerted anti-inflammatory, anti-apoptotic, and anti- necrotic effects, while it worsened the septic rat heart histology.",

AB  - Lipidomics deals with small molecules metabolomes with a mass lower than 1500. In recent years, the crucial role of lipidomes in the pathogenesis and therapy of cardiovascular events has become increasingly apparent.1-3 For example, ischemia-reperfusion (IR) injury can initiate oxidative stress that leads to harmful changes in membrane lipids, with an unwanted accumulation of fatty acids that leads to lipotoxicity. Lipid analysis provides additional insight into the pathogenesis of IR disorders and reveals new targets for drug action. A therapeutic approach to reperfusion lipotoxicity involves attenuation of fatty acids overload, i.e., their transport to adipose tissue and/or inhibition of the adverse effects of fatty acids on cell damage and death. The latter option involves using PPAR agonists and drugs that modulate the transport of fatty acids via carnitine into the interior of the mitochondria or the redirection of long-chain fatty acids to peroxisomes. Regarding platelet functions, polyunsaturated fatty acids play a role in increasing platelet reactivity, and that the prothrombotic phenotype plays a crucial role in the occurrence of major adverse cardiovascular events. The ongoing increase in cardiovascular diseases incidence emphasizes the importance of research linking lipids and platelet function. In particular, the rebound phenomenon that accompanies clopidogrel discontinuation in patients receiving dual antiplatelet therapy has been associated with changes in the lipid profile. Our many years of research underline the importance of reduced HDL values for the risk of such a rebound effect and the occurrence of thromboembolic events. Lipids are otherwise a heterogeneous group of molecules, and their signaling molecules are not deposited but formed “on-demand” in the cell. On the other hand, exosomes transmit lipid signals between cells, and the profile of such changes can be monitored by lipidomics. Changes in the lipid profile are organ-specific and may indicate new drug action targets.

AB  - It is well known that stress changes levels of pituitary hormones in the bloodstream and in the pituitary itself. However, almost nothing is known about the impact of stress on histological and stereological parameters of the growth hormone producing cells (somatotrophs-GH cells). The aim of the present study was to investigate the effect of: acute and repeated immobilization; acute and repeated restraint on histological and morphofunctional parameters of somatotrophs in adult Wistar rats. Changes in the pituitary gland volume; the volume density and volume of somatotrophs following acute and repeated immobilization (IMO, R-IMO); acute and repeated restraint (R, R-R) were evaluated using a stereological system (newCAST), while growth hormone level within pituitary was determined by Western blot. Our results demonstrated the decrease (p < 0.05) of the pituitary volume (17%, 19%) in the IMO and R groups, respectively, and the increase in the R-R group. The volume density of GH cells decreased (p < 0.05) in the R-IMO (7%), R (26%) and R-R (18%) group in comparison to the control value. The pituitary GH content was increased (p < 0.05) after the IMO (2-fold), R (2.5-fold) and R-R (2.1-fold) as compared to the control group. These results point out that acute and repeated immobilization and/or restraint lead not only to changes in GH hormone concentration, but also modify the morphological aspects of GH cells within the rat pituitary.

AB  - We investigated the effect of long-term high-dose virgin coconut oil (VCO) supplementation on rat liver and serum lipid status. Animals were divided into two groups with 8 of them in each: normally fed (Control group) and the group fed with coconut oil at a concentration of 20% in food (VCO group). The experiment lasted for four months. On the last day of the experiment animals were killed, and blood and liver tissue were collected. In serum we measured the levels of total cholesterol (TC), high-density lipoproteins (HDL), non-HDL lipoproteins, triglycerides (TG), aspartate aminotransferase (9\.ST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). We also measured both liver and serum levels of high mobility group protein B 1 (HMGB 1) and haptoglobin (HP), as ,.vell as the liver level of NF-KB p65/ p-NF-KB p65 transcription factor, together with the histopathology analysis on liver slices and liver Comet assay. The results show that coconut oil do not change serum TC and HDL, but reduces non-HDL and TG levels (10% and 50%, respectively) comparing to control. As a result, atherogenic index of serum (AI) is strongly reduced in VCO group versus control. As for the liver status, results show that coconut supplementation increases AST, ALT and ALP levels in VCO group (50%, 30% and 60%, respectively) comparing to control. This effect is caused by the accumulation of coconut oil fat in liver, as confirmed by the histopathology showing signs of mild nonalcoholic steatohepatitis in VCO group, followed with the increased %of DNA in comet tail. The liver inflammation in VCO group is further demonstrated with the liver HP, HMGBl and p-NF-KB p65 level increase, and increase in nuclear level ofNF­kB p65, but not accompanying serum HP and HMGBl increase. In conclusion, our results show that coconut oil supplementation, despite causing mild and localized steatohepatitis, also lowers serum atherogcnic index, a predictor of cardiovascular risk.

AB  - We investigated the effect of long-term high-dose virgin coconut oil (VCO) supplementation on rat glucose homeostasis. Animals were divided into two groups with 6 of them in each: normally fed (Control group) and the group fed with coconut oil at a concentration of 20% in food (VCO group). The experiment lasted for four months. We measured fasting glycemia once a week during the entire experiment. In the last week of the experiment, we performed an oral glucose tolerance test (OGTT) and an intraperitoneal insulin tolerance test (ITT). On the last day of the experiment the fasting insulin and glyc8mia were measured in the blood of animals. The results show that coconut oil reduces weekly glycemia in VCO animals compared with controls. This effect reaches its maximum after the first two weeks of the experiment, and then slowly decreases and disappears over time of next eight weeks. As a result, the glycemia of control and VCO animals do not differ in last six weeks of the experiment. The area under the curve (AUC) presenting glycemia during whole the experiment is significantly lower in VCO animals than in the controls. The hypoglycemic effect of coconut oil is obviously dose-dependent since the amount of food (and therefore the coconut oil) that the animals eat decreases over the time. The results of the oral glucose tolerance test show that the OGTT AUC of VCO animals is significantly lower than the controls, and same is true for the insulin tolerance test. Finally, glycemia and insulin concentration in serums sampled on the last day of the experiment do not differ between VCO and Control groups, so accordingly neither HOMA-IR I and 2 (Homeostatic model assessment of insulin resistance) nor QUIC.Kl ( Quantitative Insulin Sensitivity Check Index). In conclusion, our results show beneficial effects of long-term high-dose coconut oil supplementation on rat glucose homeostasis.
