AB  - The careful monitoring of patients with mild/moderate COVID-19 is of particular importance because of the rapid progression of complications associated with COVID-19. For prognostic reasons and for the economic management of health care resources, additional biomarkers need to be identified, and their monitoring can conceivably be performed in the early stages of the disease. In this retrospective cross-sectional study, we found that serum concentrations of high-mobility group box 1 (HMGB1) and heme oxygenase-1 (HO-1), at the time of hospital admission, could be useful biomarkers for COVID-19 management. The study included 160 randomly selected recovered patients with mild to moderate COVID-19 on admission. Compared with healthy controls, serum HMGB1 and HO-1 levels increased by 487.6 pg/mL versus 43.1 pg/mL and 1497.7 pg/mL versus 756.1 pg/mL, respectively. Serum HO-1 correlated significantly with serum HMGB1, oxidative stress parameters (malondialdehyde (MDA), the phosphatidylcholine/lysophosphatidylcholine ratio (PC/LPC), the ratio of reduced and oxidative glutathione (GSH/GSSG)), and anti-inflammatory acute phase proteins (ferritin, haptoglobin). Increased heme catabolism/hemolysis were not detected. We hypothesize that the increase in HO-1 in the early phase of COVID-19 disease is likely to have a survival benefit by providing protection against oxidative stress and inflammation, whereas the level of HMGB1 increase reflects the activity of the innate immune system and represents levels within which the disease can be kept under control.

AB  - Acute ischemia/reperfusion (I/R) liver injury is a clinical condition challenging to treat. Meldonium
is an anti‑ischemic agent that shifts energy production from fatty acid oxidation to less oxygen‑
consuming glycolysis. Thus, we investigated the effects of a 4‑week meldonium pre‑treatment
(300 mg/kg b.m./day) on the acute I/R liver injury in Wistar strain male rats. Our results showed that
meldonium ameliorates I/R‑induced liver inflammation and injury, as confirmed by liver histology,
and by attenuation of serum alanine‑ and aspartate aminotransferase activity, serum and liver
high mobility group box 1 protein expression, and liver expression of Bax/Bcl2, haptoglobin, and
the phosphorylated nuclear factor kappa‑light‑chain‑enhancer of activated B cells. Through the
increased hepatic activation of the nuclear factor erythroid 2‑related factor 2, meldonium improves
the antioxidative defence in the liver of animals subjected to I/R, as proved by an increase in serum
and liver ascorbic/dehydroascorbic acid ratio, hepatic haem oxygenase 1 expression, glutathione
and free thiol groups content, and hepatic copper‑zinc superoxide dismutase, manganese superoxide
dismutase, catalase, glutathione peroxidase, and glutathione reductase activity. Based on our results,
it can be concluded that meldonium represent a protective agent against I/R‑induced liver injury, with
a clinical significance in surgical procedures.

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.

AB  - The effects of twelve weeks of supplementation with fullerene C60 olive/coconut oil solution on a broad spectrum of parameters in rats were examined. The tissue bioaccumulation of C60 was shown to be tissue-specific, with the liver, heart, and adrenal glands being the organs of the greatest, and the kidney, brain, and spleen being the organs of the smallest accumulation. C60 did not change aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase serum activities level, nor the damage of liver cells DNA. There were no effects of fullerene on prooxidant-antioxidant balance in the liver, kidney, spleen, heart, and brain, nor any visible harmful effects on the liver, heart, aorta, spleen, kidney, and small intestine histology. Fullerene changed the gut microbiota structure towards the bacteria that ameliorate lipid homeostasis, causing a serum triglycerides concentration decrease. However, C60 significantly increased the insulin resistance, serum ascorbate oxidation, and brain malondialdehyde and advanced oxidation protein products level. The deteriorative effects of C60 on the brain and serum could be attributed to the specific physicochemical composition of these tissues, potentiating the C60 aggregation or biotransformation as the key element of its pro-oxidative action.

AB  - Non-diabetic and alloxan-induced diabetic rats were fed with standard laboratory food enriched with 20% virgin coconut oil for 16 weeks. In non-diabetic animals coconut oil improved insulin sensitivity and ability to control glycaemia and decreased the serum triglycerides for almost 50% in comparison with controls. Supplementation with coconut oil caused liver steatosis in both non-diabetic and diabetic animals. However, the severity of steatosis was lower in diabetic animals compared to non-diabetic animals. Coconut oil had no effects on heart histology, ascending and abdominal aorta wall thickening and atherosclerotic plaques development neither in non-diabetic nor in diabetic animals. While alloxan treatment caused Type I diabetes in rats, supplementation with coconut oil in combination with the alloxan unexpectedly resulted in Type II diabetes.

abstract = "Non-diabetic and alloxan-induced diabetic rats were fed with standard laboratory food enriched with 20% virgin coconut oil for 16 weeks. In non-diabetic animals coconut oil improved insulin sensitivity and ability to control glycaemia and decreased the serum triglycerides for almost 50% in comparison with controls. Supplementation with coconut oil caused liver steatosis in both non-diabetic and diabetic animals. However, the severity of steatosis was lower in diabetic animals compared to non-diabetic animals. Coconut oil had no effects on heart histology, ascending and abdominal aorta wall thickening and atherosclerotic plaques development neither in non-diabetic nor in diabetic animals. While alloxan treatment caused Type I diabetes in rats, supplementation with coconut oil in combination with the alloxan unexpectedly resulted in Type II diabetes. The development of severe insulin resistance and deterioration in serum lipid profile implied that the use of coconut oil is contraindicated in diabetic condition.",

AB  - Acute renal ischemia/reperfusion (I/R) is a temporary restriction of kidney blood supply, followed by blood flow restoration and re-oxygenation. During I/R, decreased oxygen supply disturbs ion transport, intracellular ATP, calcium and pH levels, and numerous signalling pathways. Upon reperfusion, a restoration of oxygen level rises a reactive oxygen species generation, cytokines and chemokines release from activated tissue-resident macrophages, and infiltration of pro-inflammatory neutrophils into ischemic tissues. All these changes result in cell swelling and rupturing, and consequent necrotic or apoptotic cell death. Meldonium is an anti-ischemic drug clinically used to treat myocardial and cerebral ischemia, which acts by shifting energy production from fatty acid oxidation to glycolysis. We investigated the effects of a 4-week meldonium pre-treatment with 300 mg/kg b.m./day of rats subjected to a well-established experimental model of renal I/R, with ischemia lasting for 45 minutes, followed by 4 hours of reperfusion. The degree of apoptosis and necrosis was evaluated by measuring renal pro-apoptotic Bax and anti-apoptotic Bcl-2 ratio, serum and kidney levels of necrotic marker - high mobility group box 1 protein (HMGB1), together with the kidney histology analysis. Our results showed that apoptotic and necrotic cell death occur simultaneously under I/R conditions, judging by the renal Bax/Bcl2 ratio rise (2.7-fold), increase in serum (22%) and renal (30%) levels of HMGB1, as well as severe tubular necrosis with dilatation of the tubular structure, cast formation, tubular lumina dilatation, brush border reduction, and loss in some renal areas cells. Meldonium pretreatment reduced the elevated Bax/Bcl2 ratio by 35%, as well as the serum and renal HMGB1 levels by 20% and notably diminished histological evidence of renal I/R necrotic injury, especially regarding tubular structures. These findings proved that meldonium protects renal cells against I/R-induced necrosis and apoptosis.

AB  - Oxidative stress (OS) represents an imbalance of free radicals production and antioxidant defense in which the extensive pro-oxidant production may cause damage to cell structures. OS is the major event occurring in pathogenesis of liver disorders, ranging from metabolic to proliferative disorders. Cadmium is a highly toxic and widespread toxicant. Cadmium itself is unable to generate free radicals directly, as cadmium does not undergo redox cycling. However, indirect generation of various radicals involving the superoxide radical, hydroxyl radical, and nitric oxide has been reported. One of the biologically most relevant features of C60 fullerene is the ability to quench various free radicals, behaving as a “free radical sponge.” Conversely, photosensitization of C60 yields highly reactive singlet oxygen or superoxide anion. Therefore, the dual property of fullerene to either quench or generate cell-damaging reactive oxygen species could be potentially exploited for their development as cytoprotective or cytotoxic agents.

AB  - The aim of this study was to investigate the potential protective effect of virgin coconut oil (VCO) on oxidative stress parameters in the liver, kidneys and heart of alloxan-induced (150 mg kg-1 i.p.-1) diabetes in rats. Our results showed that daily supplementation of VCO (20% of food) for 16 weeks significantly (p < 0.05) ameliorates some deleterious effects caused by alloxan. VCO reduced the diabetes-related increase in food (82.15 ± 1.49 vs. 145.51 ± 4.81 g per kg b.m. per day) and water (305.49 ± 6.09 vs. 583.98 ± 14.80 mL per kg b.m. per day) intake, and the decrease in the body mass gain (0.56 ± 0.16 vs. -2.13 ± 0.49 g per 100 g b.m. per week). In all three tissues, diabetes caused an increase in the concentration of total glutathione and sulfhydryl groups, and catalase and glutathione S-transferase activities, without changes in superoxide dismutase activity. Glutathione peroxidase activity was increased in the kidneys and heart, but not in the liver of the diabetic animals, while glutathione reductase activity was increased in the liver and the kidneys, and not in the heart. The simultaneous VCO supplementation increased the concentration of the sulfhydryl group in all three tissues of diabetic animals and decreased the glutathione S-transferase activity and glutathione concentration, without affecting the glutathione reductase activity. In the liver of diabetic animals it decreased superoxide dismutase, catalase and glutathione peroxidase activities, in the heart catalase and glutathione peroxidase activities, and in the kidney catalase activity only. The results of canonical discriminant analysis of oxidative stress parameters revealed that VCO exerts its effects in a tissue-specific manner.

AB  - Plant vegetation accumulates polycyclic aromatic hydrocarbons (PAHs) among which benzo[a]pyrene (B[a]P) is recognized as being very toxic, including cancerogenic. Lymantria dispar L. larvae are sensitive to changes in the environment, providing potential signs of pollutant presence. We examined the chronic effects of two concentrations of B[a] P on the activity of carboxylesterase (CaE), acetylcholinesterase (AChE) and heat shock protein 70 (Hsp70) levels in the brain tissue of two populations of L. dispar larvae, originating from unpolluted and polluted habitats. We found that the relative growth rate was significantly lower in both populations and that only larvae from polluted forests were sensitive to low B[a]P concentrations, exhibiting a significant increase in brain tissue CaE activity and Hsp70 concentration. AChE activity showed no changes in response to B[a]P exposure in either population. Examined biochemical parameters indicate that their sensitivity to chronic treatment with B[a]P was highly dependent on the pre-exposure history of L. dispar larvae, suggesting that they could be promising biomarkers of B[a]P and PAH pollution in forest ecosystems

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.
