Abstract
One of the most common nerve palsies - common fibular nerve palsy - can be caused by the variant small sesamoid bone in the posterolateral compartment of the knee joint known as the fabella. We compared and reviewed all reported cases of common fibular nerve palsy due to fabellae in the English literature. Compression can develop spontaneously or post-surgically (total knee arthroplasty). Symptoms progress rapidly to complete foot drop. Among all the cases reviewed, 68.42% were males with a median age of 39.39 years. Fabella compression was more common in the left common fibular nerve (CFN) (63.16%). Both big (23 × 20 × 16 mm) and small (5 × 5 mm) fabellae can be responsible for compression. While diagnosis can be problematic, the treatment (either surgical fabellectomy or conservative) is relatively easy and brings quick improvement.

Abstract
Manganese (Mn) is an essential trace element with unique functions in the body; it acts as a cofactor for many enzymes involved in energy metabolism, the endogenous antioxidant enzyme systems, neurotransmitter production, and the regulation of reproductive hormones. However, overexposure to Mn is toxic, particularly to the central nervous system (CNS) due to it causing the progressive destruction of nerve cells. Exposure to manganese is widespread and occurs by inhalation, ingestion, or dermal contact. Associations have been observed between Mn accumulation and neurodegenerative diseases such as manganism, Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis. People with genetic diseases associated with a mutation in the gene associated with impaired Mn excretion, kidney disease, iron deficiency, or a vegetarian diet are at particular risk of excessive exposure to Mn. This review has collected data on the current knowledge of the source of Mn exposure, the experimental data supporting the dispersive accumulation of Mn in the brain, the controversies surrounding the reference values of biomarkers related to Mn status in different matrices, and the competitiveness of Mn with other metals, such as iron (Fe), magnesium (Mg), zinc (Zn), copper (Cu), lead (Pb), calcium (Ca). The disturbed homeostasis of Mn in the body has been connected with susceptibility to neurodegenerative diseases, fertility, and infectious diseases. The current evidence on the involvement of Mn in metabolic diseases, such as type 2 diabetes mellitus/insulin resistance, osteoporosis, obesity, atherosclerosis, and non-alcoholic fatty liver disease, was collected and discussed.

Abstract
Glaucoma is a leading cause of irreversible blindness and is characterized by increased intraocular pressure (IOP) and progressive optic nerve damage. The current therapeutic approaches for glaucoma management, such as eye drops and oral medications, face challenges including poor bioavailability, low patient compliance, and limited efficacy. In recent years, nanotechnology has emerged as a promising approach to overcome these limitations and revolutionize glaucoma treatment. In this narrative review, we present an overview of the novel nanotechnologies employed in the treatment of primary open-angle glaucoma. Various nanosystems, including liposomes, niosomes, nanoparticles, and other nanostructured carriers, have been developed to enhance the delivery and bioavailability of antiglaucoma drugs. They offer advantages such as a high drug loading capacity, sustained release, improved corneal permeability, and targeted drug delivery to the ocular tissues. The application of nanotechnologies in glaucoma treatment represents a transformative approach that addresses the limitations of conventional therapies. However, further research is needed to optimize the formulations, evaluate long-term safety, and implement these nanotechnologies into clinical practice. With continued advancements in nanotechnology, the future holds great potential for improving the management and outcomes of glaucoma, ultimately preserving vision and improving the lives of millions affected by this debilitating disease.

Abstract
Dyslipidaemia is a disorder of the lipid metabolism, caused mainly by poor eating habits. The most severe consequence of an inappropriate diet is the development of atherosclerosis and hepatic steatosis. It is generally believed that a change in nutrition, and increased physical activity can eliminate these health problems. The contemporary research and therapies used to treat dyslipidemia mainly focus on lowering the triglyceride and cholesterol levels. However, disturbances in trace element homeostasis or the accumulation of toxic elements can also affect physiological processes, and be involved in the development of metabolically mediated diseases. The present study aimed to determine the mineral profiles of liver and brain tissues collected at autopsy (n = 39) in groups of people with hepatic steatosis (n = 5), atherosclerosis (n = 9), hepatic steatosis, and atherosclerosis (n = 16), and others without the selected disorders (n = 9). Concentrations of 51 elements were analysed via inductively coupled plasma mass spectrometry (ICP-MS) after the initial wet mineralisation of the samples with nitric acid. The results obtained allow us to conclude that the hepatic steatosis group suffers from a deficiency of important trace elements, such as copper, zinc, and molybdenum (p < 0.05), whereas the group with atherosclerosis is characterised by elevated levels of cadmium in the liver tissue (p = 0.01). Analysing the mean values of the element concentrations measured in 11 brain areas, statistically significant higher levels of calcium and copper (p < 0.001) were found in the atherosclerosis group, compared to the hepatic steatosis group, confirming the involvement of these elements in the pathogenesis of atherosclerosis. In addition, an accumulation of cadmium, lead, titanium, and strontium in the brain tissue was observed in the atherosclerosis group. While the accumulation of individual elements differs in different parts of the brain, the differences in the cadmium content (p < 0.05) between the study groups apply to the whole brain, except for the nucleus accumbens septi area, where a statistically significant titanium accumulation occurs in the atherosclerosis and steatosis groups, compared to the others (p < 0.05). In addition, the disruption of elemental homeostasis in the brain of a single case with bipolar disorder, and a case with hip replacement was observed. Our results confirm the involvement of chemical elements in the pathogenesis of selected metabolic diseases, and the need for further studies in larger populations.

Abstract
The most important function of the skin is to protect the body against harmful mechanical, physical and chemical factors. Its regenerative capacity is sufficient for self-repair in the event of damage, for example, during tattooing, which can be treated as an invasive procedure introducing pigment molecules into skin layers. In the present research on tattoo pigment deposition, the structure of the dermis and epidermis was evaluated using the standard histological technique with hematoxylin and eosin staining. In addition, statistically significant differences between the depth of pigment deposition on the one hand and age, dermis and epidermis thickness and tattoo location on the other were demonstrated.

Abstract
Aluminium (Al) is the most ubiquitous metal in the Earth's crust. Even though its toxicity is well-documented, the role of Al in the pathogenesis of several neurological diseases remains debatable. To establish the basic framework for future studies, we review literature reports on Al toxicokinetics and its role in Alzheimer's disease (AD), autism spectrum disorder (ASD), alcohol use disorder (AUD), multiple sclerosis (MS), Parkinson's disease (PD), and dialysis encephalopathy (DE) from 1976 to 2022. Despite poor absorption via mucosa, the biggest amount of Al comes with food, drinking water, and inhalation. Vaccines introduce negligible amounts of Al, while the data on skin absorption (which might be linked with carcinogenesis) is limited and requires further investigation. In the above-mentioned diseases, the literature shows excessive Al accumulation in the central nervous system (AD, AUD, MS, PD, DE) and epidemiological links between greater Al exposition and their increased prevalence (AD, PD, DE). Moreover, the literature suggests that Al has the potential as a marker of disease (AD, PD) and beneficial results of Al chelator use (such as cognitive improvement in AD, AUD, MS, and DE cases).

Abstract
BACKGROUND The study assessed the effect of smectites (bentonite and zeolite) used as natural sorbents in the diet of pigs on feed digestibility, health parameters, the severity of anatomo-histological changes in organs, and the accumulation of volatile pollutants in organs. MATERIAL AND METHODS The study was conducted using fattening pigs (crossbreds from multiple breeds) assigned to three groups - a control (C) and two experimental groups (A and B), with 240 pigs in each group (3 replicates × 80). The animals in group C received a standard complete diet, while groups A and B received diets with 1.5% composed smectite sorbents. The feed and faeces were analysed for content of dry matter, crude ash, crude protein, ether extract, and crude fibre. The content of P was determined using a Helios Alpha UV-VIS spectrophotometer. Whole blood was analysed for haematological parameters and serum for biochemical parameters. Tissue samples were collected for analysis of volatile substances and histological analysis. After slaughter, samples of the lungs, liver, kidneys and jejunum were collected for morphological evaluation, and samples of the perirenal fat, liver, kidneys, lungs and brain for headspace gas chromatography (GC) to determine the levels of volatile toxic substances. RESULTS A statistical increase in the digestibility of crude fibre and an increase in that of P were observed in both experimental groups (A and B) in comparison to the control. The whole blood and serum of the pigs from the control group had statistically significantly higher levels of creatinine, urea, and Mg and a higher WBC count compared to both experimental groups (A and B). CONCLUSIONS The feed additives were not shown to have a negative effect on the health parameters analysed or on accumulation of pollutants in selected tissues. No significant effect on the digestibility of most nutrients was observed; only an increase in the digestibility of crude fibre and a decrease in P digestibility were noted in the experimental groups.

Abstract
Postmortem carbon monoxide (CO) and hydrogen cyanide (HCN) diffusion under ambient conditions was assessed in a human cadaver model. The main objective of this study was to determine whether the postmortem diffusion of HCN and CO greatly affected the determination of HCN, carboxyhemoglobin (COHb), and carboxymyoglobin (COMb). Layered samples of blood, musculocutaneous, and muscular specimens were collected from the adult cadavers and placed in the tight chambers designed for the purpose of this experiment. The specimens were treated with CO and HCN for 24 h. COHb and COMb were determined using headspace gas chromatography (GC) with an O-FID detector while the HCN values were assessed using a GC headspace with an NPD detector. It was shown that the skin substantially limited the diffusion of CO which penetrated the superficial layers of the muscle very slightly, all the while not affecting the blood level of COHb in the 4.5 cm layer of the muscle located underneath. There were no differences regarding the CO diffusion between superficially charred and thermally coagulated compared to that observed in intact integuments. In addition, the cutaneous sample deprived of the adipose layer was not shown to be a barrier to the moderate diffusion of CO into the blood layer below. HCN was found to easily diffuse from the skin to the blood vessels (vein specimens), and partial charring and thermocoagulation of the superficial muscular layer favored the diffusion of cyanides into the tissues. Similarly to CO, HCN diffusion to the blood and muscles was greatly limited by the adipose layer.

Abstract
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has become a worldwide threat resulting in a pandemic in 2020. SARS-CoV-2 infection manifests itself as coronavirus disease 2019 (COVID-19) that is evidenced in a vast number of either specific or nonspecific symptoms. Except for typical (but nonspecific) symptoms such as fever, dry cough, or muscle weakness, the infected patients might also present atypical symptoms including neurological, dermatological, or ophthalmic manifestations. This paper summarizes the current state of knowledge regarding the onset, progression, and types of ophthalmic symptoms induced by SARS-CoV-2 infection recognized amongst the infected patients.

Abstract
Although nutritional-risk scoring systems allow the determination of the patient’s malnutrition at admission, additional tools might be useful in some clinical scenarios. Previous medical history could be unavailable in unconscious or demented patients. This study aimed to assess the ketone bodies serum levels in patients undergoing elective surgeries and to determine the possible correlation between ketone bodies serum levels and preoperative body weight loss. The study included 21 patients who underwent elective surgery. Hyperketonemia, defined as ketone bodies over 1 mmol/L, was observed in seven (33.3%) patients. Patients with hyperketonemia had significantly higher preoperative percentage body weight loss (p = 0.04) and higher nutritional risk scores prior to surgery (p = 0.04). Serum glucose and the percentage of body weight loss were associated with increased ketone bodies serum levels (Odds Ratios: 0.978 (0.961–0.996, p = 0.019) and 1.222 (1.0–1.492, p = 0.05), respectively). A significant linear correlation was found between the percentage of body weight loss and both ketones bodies (r2 = 0.25, p = 0.02) and albumin serum levels (r2 = 0.19, p = 0.04). Our study’s results might suggest a positive association between preoperative body weight loss and ketone bodies serum levels. The observation between increased ketone bodies serum levels in patients and preoperative body mass loss merits further research.

Abstract
Human Papilloma Virus (HPV) is one of the most common sexually transmitted infections worldwide. HPV infection has a strong relationship with the onset of cervix uteri, vagina, penis, anus, and oropharynx, but also tonsils and tongue cancers. Some epidemiological data indicate that except for gynecologic cancers, HPV infection can be one of the risk factors associated with a greater risk of induction and progression of gastrointestinal cancers. Data, however, remain contradictory and definite conclusions cannot be drawn, so far. The following review aims to organize recent evidence and summarize the current state of knowledge regarding the association between HPV infection and gastrointestinal tumors primarily focusing on esophageal, liver, gastric, colorectal, and anal cancers.

Abstract
Optic neuropathies constitute a group of conditions with various etiologies and might be caused by different factors; we can distinguish the genetic and acquired causes of optic neuropathies. Even though the symptoms are not highly specific, this condition is primarily characterized by unilateral or bilateral vision loss with worsening color detection. The loss may be acute or gradual depending on the causation. In this article, we included a specification of toxic optic neuropathy (TON) mainly triggered by alcohol abuse and also the usage of other substances, including drugs or methanol, as well as intoxication by metals, organic solvents, or carbon dioxide. Nutritional deficiencies, vitamin absorption disorder, and anemia, which usually appear during excessive alcohol intake, and their effect on the etiology of the optic neuropathy have been likewise discussed.

Abstract
Trace element accumulation varies in different human tissues. Distribution of several elements was found to be disrupted in the case of excessive alcohol consumption, causing negative effects and exacerbation of pathological processes in the liver. In this study, we analyzed the levels and interactions between seven trace elements including calcium (Ca), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), potassium (K), and magnesium (Mg), manganese (Mn), sodium (Na), zinc (Zn), and selenium (Se) in individuals with alcohol-use disorder (AUD) and patients without AUD (control group). The liver samples were collected during autopsy from 39 individuals with AUD and 45 control subjects. Elemental composition inductively coupled plasma optical emission spectrometry (ICP-OES) after wet mineralization by nitric acid was applied for the evaluation of the samples. Positive correlations dominated in the AUD group, mainly in relation to Mg, which strongly positively correlated with Ca, Mn, Fe; K correlated with Mn and Zn, and Cu positively correlated with K and Zn. The strongest positive correlation in the AUD group was observed for the Mg-Mn pair (r = 0.87). Significant statistical differences (p < 0.05) between the groups concerned the average concentration of Co, Cu, Mn, and Mg, which were lower in the AUD group, and Fe, the level of which was significantly higher in the AUD group compared to the control group. Evaluation of the chronic alcohol consumption effect on the accumulation of trace elements in the liver allows a better understanding of the pathological processes taking place in this organ.

Abstract
In view of the scarcity of literature data on the use of radiological imaging techniques in forensic veterinary medicine, while at the same time the number of reported crimes against animals involving the use of firearms is rising, this paper attempts to assess the usefulness of radiography and computed tomography (CT) in the post-mortem diagnosis of gunshot wounds (GSW) in comparison to classic necropsy. The design of the experiment was as follows: preparation of the research material (13 dog carcasses), shooting of the material from different distances (1.5 and 12 m, plus one contact shot to the head) and using different types of ammunition, followed by X-rays and CT scans in each case to examine the injuries resulting from the shot. The final steps of the experiment were photographic documentation and autopsy by the Virchow method. In the examined material, post-traumatic bone lesions and the presence of metallic foreign bodies were successfully imaged by both radiography and CT. GSW analysis using CT provided much better data quality and some additional information. Two general conclusions can be drawn from the results of the experiment. First, damage caused by gunshots is correlated with the calibre, initial velocity and kinetic energy of the projectile, as well as the distance from the muzzle of the gun to the object shot. Second, radiological examination is useful in preparing forensic veterinary opinions. Used as a complement to classic necropsy, they increase the possibility of an accurate post-mortem diagnosis of shooting victims.

Abstract
Modern technologies enable the exchange of information about the expansion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the continually increasing number of the coronavirus disease 2019 (COVID-19) cases almost in real time. The gravity of a current epidemiological situation is represented by the mortality rates, which are scrupulously updated daily. Performing autopsies on patients with either suspected or confirmed COVID-19 is of high importance since these might not only improve clinical management but also reduce the risk of SARS-CoV-2 infection expansion. The following paper aimed to present the most crucial aspects of SARS-CoV-2 infection from the point of view of forensic experts and pathologists, recommendations and safety precautions regarding autopsies, autopsy room requirements, possible techniques, examinations used for effective viral detection, recommendations regarding burials, and gross and microscopic pathological findings of the deceased who died due to SARS-CoV-2 infection. Autopsies remain the gold standard for determining the cause of death. Therefore, it would be beneficial to perform autopsies on patients with both suspected and confirmed COVID-19, especially those with coexisting comorbidities.

Abstract
Metal-based carbon monoxide (CO)-releasing molecules have been shown to exert anti-inflammatory and anti-oxidative properties maintaining gastric mucosal integrity. We are interested in further development of metal-free CO-based therapeutics for oral administration. Thus, we examine the protective effect of representative CO prodrug, BW-CO-111, in rat models of gastric damage induced by necrotic ethanol or aspirin, a representative non-steroidal anti-inflammatory drug. Treatment effectiveness was assessed by measuring the microscopic/macroscopic gastric damage area and gastric blood flow by laser flowmetry. Gastric mucosal mRNA and/or protein expressions of HMOX1, HMOX2, nuclear factor erythroid 2-related factor 2, COX1, COX2, iNos, Anxa1 and serum contents of TGFB1, TGFB2, IL1B, IL2, IL4, IL5, IL6, IL10, IL12, tumor necrosis factor α, interferon γ, and GM-CSF were determined. CO content in gastric mucosa was assessed by gas chromatography. Pretreatment with BW-CO-111 (0.1 mg/kg, i.g.) increased gastric mucosal content of CO and reduced gastric lesions area in both models followed by increased GBF. These protective effects of the CO prodrug were supported by changes in expressions of molecular biomarkers. However, because the pathomechanisms of gastric damage differ between topical administration of ethanol and aspirin, the possible protective and anti-inflammatory mechanisms of BW-CO-111 may be somewhat different in these models.

Abstract
Tubal diseases are responsible for 25% to 35% of female infertility. Laparoscopic chromopertubation is the gold standard for assessing tubal patency when female infertility is suspected. Intravasation is a complication of intrauterine procedures involving the passage of fluid filling the uterine cavity into the bloodstream through endometrial vessels (from the myometrial veins to the uterine venous plexuses). This complication has been described during hysterosalpingography and sonohysterosalpingography. We herein present a report of three cases in which severe intravasation occurred during laparoscopic chromopertubation using methylene blue as a contrast agent. The intravasation manifested as green urine (i.e., the "green urine sign"). The presence of methylene blue in the urine and blood was confirmed by laboratory tests. All three patients had risk factors for intravasation as described in the literature (unilateral or bilateral tubal obstruction, endometriosis, and previous intrauterine procedures for Mullerian duct anomalies and Asherman's syndrome). The green urine sign appeared a few hours after laparoscopic chromopertubation and spontaneously resolved after 24 hours. Cystoscopy was performed to rule out bladder injury. All three patients required only clinical observation.

Abstract
The modern consumer is concerned not only for meat quality, but also about animal welfare and the environment. Studies were conducted to determine the concentration of gaseous residues in the tissues of rabbits. For this purpose, gaseous air pollutants were measured at the height of rabbit cages. Immediately after slaughter, samples were taken for analysis to determine the level of residual pollutants in the tissues (blood, perirenal fat and lung). Headspace gas chromatography was performed on the tissue samples to test for volatile toxic substances. Gas residues of 11 compounds were determined in the samples of blood, perirenal fat and lungs. The same chemicals were present in the air of the farm and the animal tissues, which may indicate their capacity for bioaccumulation. We recommend that the results should be used to develop guidelines regarding the welfare of meat rabbits and requirements for laboratory rabbits.

Abstract
Exposure to acidic gastric content due to malfunction of lower esophageal sphincter leads to acute reflux esophagitis (RE) leading to disruption of esophageal epithelial cells. Carbon monoxide (CO) produced by heme oxygenase (HMOX) activity or released from its donor, tricarbonyldichlororuthenium (II) dimer (CORM-2) was reported to protect gastric mucosa against acid-dependent non-steroidal anti-inflammatory drug-induced damage. Thus, we aimed to investigate if CO affects RE-induced esophageal epithelium lesions development. RE induced in Wistar rats by the ligation of a junction between pylorus and forestomach were pretreated i.g. with vehicle CORM-2; RuCl3; zinc protoporphyrin IX, or hemin. CORM-2 was combined with NG-nitro-L-arginine (L-NNA), indomethacin, capsazepine, or capsaicin-induced sensory nerve ablation. Esophageal lesion score (ELS), esophageal blood flow (EBF), and mucus production were determined by planimetry, laser flowmetry, histology. Esophageal Nrf-2, HMOXs, COXs, NOSs, TNF-α and its receptor, IL-1 family and IL-1 receptor antagonist (RA), NF-κB, HIF-1α, annexin-A1, suppressor of cytokine signaling (SOCS3), TRPV1, c-Jun, c-Fos mRNA/protein expressions, PGE2, 8-hydroxy-deoxyguanozine (8-OHdG) and serum COHb, TGF-β1, TGF-β2, IL-1β, and IL-6 content were assessed by PCR, immunoblotting, immunohistochemistry, gas chromatography, ELISA or Luminex platform. Hemin or CORM-2 alone or combined with L-NNA or indomethacin decreased ELS. Capsazepine or capsaicin-induced denervation reversed CORM-2 effects. COHb blood content, esophageal HMOX-1, Nrf-2, TRPV1 protein, annexin-A1, HIF-1α, IL-1 family, NF-κB, c-Jun, c-Fos, SOCS3 mRNA expressions, and 8-OHdG levels were elevated while PGE2 concentration was decreased after RE. CO donor-maintained elevated mucosal TRPV1 protein, HIF-1 α, annexin-A1, IL-1RA, SOCS3 mRNA expression, or TGF-β serum content, decreasing 8-OHdG level, and particular inflammatory markers expression/concentration. CORM-2 and Nrf-2/HMOX-1/CO pathway prevent esophageal mucosa against RE-induced lesions, DNA oxidation, and inflammatory response involving HIF-1α, annexin-A1, SOCS3, IL-1RA, TGF-β-modulated pathways. Esophagoprotective and hyperemic CO effects are in part mediated by afferent sensory neurons and TRPV1 receptors activity with questionable COX/PGE2 or NO/NOS systems involvement.

Abstract
Endogenous gaseous mediators, such as nitric oxide, hydrogen sulfide or carbon monoxide (CO) are known to exert anti-inflammatory and anti-oxidative activity due to modulation of various molecular pahtways. Therefore, we aimed to investigate if CO released from tricarbonyldichlororuthenium (II) dimer (CORM-2) prevents gastric mucosa against ischemia/reperfusion (I/R)-induced injury in male Wistar rats. Animals were pretreated i.g. With vehicle (DMSO and saline, 1:10), CORM-2 (1, 5 or 10 mg/kg) or zinc protoporphyrin IX (ZnPP, 10 mg/kg i.p.), the HMOXs inhibitor. In separate series, rats were pretreated with CORM-2 (5 mg/kg) applied in combination with glibenclamide (10 mg/kg i.g.), NG-nitro-l-arginine (L-NNA, 20 mg/kg i.p.), 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 10 mg/kg i.p.) or indomethacin (5 mg/kg i.p.). I/R-injuries were induced by clamping celiac artery for 30 min (I) followed by removal of the clamp to obtain R for 3 h. The macroscopic and microscopic area of gastric damage, mucus production and protein expression for HMOX-1/Nrf-2 was determined by planimetry, histology and immunohistochemistry, respectively. Gastric mucosal HMOX-1, HMOX-2, COX-1, COX-2, Kir6.1, Sur2, sGC-α1, sGC-α2, iNOS and eNOS mRNA expression was assessed by real-time PCR. COHb in blood and gastric mucosal CO concentration was analyzed by gas chromatography. Serum content of TGF-β1, TGF-β2, TGF-β3, IL-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12, TNF-α, IFN-γ, GM-CSF was evaluated using Luminex platform. PGE2 concentration and 8-hydroxyguanozine (8-OHG) concentration in gastric mucosa was determined by ELISA. Exposure to I/R induced extensive hemorrhagic erosions in gastric mucosa pretreated with vehicle as compared with intact rats and the area of this gastric damage was reduced by pretreatment with CORM-2 (5 mg/kg i.g.). This effect of CO donor was accompanied by the increased PGE2 content and a significant decrease in 8-OHG and expression of pro- and anti-inflammatory markers mRNA and proteins. Concurrent treatment of CORM-2 with glibenclamide, L-NNA, ODQ but not with indomethacin significantly increased the area of I/R-induced injury and significantly decreased GBF as compared with the group treated with CORM-2 alone. We conclude that CO releasing CORM-2 prevents gastric mucosal oxidative damage induced by I/R improving GBF, decreasing DNA oxidation and inflammatory response on systemic level. This CO-gastroprotection is mediated by the activity of sGC, NOS and K-ATP channels. CO delivered from its donor maintained physiological gastric mucosal PGE2 concentration but the involvement of endogenous COX in beneficial activity of this gaseous mediator at least in this model is questionable.

Abstract
This study evaluated the effect of androsterone (AND), a metabolite of testosterone, on the ability of selected classical and novel antiepileptic drugs to prevent seizures caused by maximal electroshock (MES), which may serve as an experimental model of human generalized tonic-clonic seizures in mice. Single intraperitoneal (i.p.) administration of AND (80 mg kg-1) significantly raised the threshold for convulsions in the MES seizure threshold test. Lower doses of AND (5, 10, 20, and 40 mg kg-1) failed to change the threshold. AND at a subthreshold dose of 40 mg kg-1 significantly enhanced the protective activity of carbamazepine, gabapentin, and phenobarbital against MES-induced seizures decreasing their median effective doses (ED50) values ± SEM from 8.59 ± 0.76 to 6.05 ± 0.81 mg kg-1 (p = 0.0308) for carbamazepine, from 419.9 ± 120.6 to 111.5 ± 41.1 mg kg-1 (p = 0.0405) for gabapentin, and from 20.86 ± 1.64 to 10.0 ± 1.21 mg kg-1 (p = 0.0007) for phenobarbital. There were no significant changes in total brain concentrations of carbamazepine, gabapentin, and phenobarbital following AND administration. This suggests that the enhancing effects of AND on the protective activity of these antiepileptic drugs are not related to pharmacokinetic factors. A lower dose of AND (20 mg kg-1) had no effect on the protective activity of carbamazepine, gabapentin, and phenobarbital. AND administered at a dose of 40 mg kg-1 failed to change the anticonvulsant activity of lamotrigine, oxcarbazepine, phenytoin, topiramate, and valproate in the MES test. In the chimney test, AND given at a dose enhancing the protective activity of carbamazepine, gabapentin, and phenobarbital (which alone was without effect on motor performance of mice) did not affect impairment of motor coordination produced by the antiepileptics. Our findings recommend further preclinical and clinical research on AND in respect of its use as adjuvant therapy in the management of epilepsy in men with deficiency of androgens.

Abstract
Different extraction and clean-up protocols, based on either the dispersive solid-phase extraction (d-SPE) and the quick, easy, cheap, effective, rugged, and safe (QuEChERS) approach, were optimized and compared for the determination of selected bisphenols such as bisphenol A (BPA) and bisphenol S (BPS) in breast milk samples. QuEChERS-based sample preparation procedure was optimized by evaluation of different clean-up sorbents including zirconium-based sorbents (Z-Sep and Z-Sep Plus) and primary secondary amine. Negligible matrix interference was observed for most of the analytes due to application of 45 mg Z-Sep or 45 mg Z-Sep + 5 mg Z-Sep Plus sorbents in d-SPE clean-up step. Acceptable analytical performance for the BPA and BPS was observed with recoveries percentage in the range of 70-92% and RSD less than 15%. The pilot study was performed by applying HPLC with diode-array detection, and optimized procedures were transferred to the LC triple-quadrupole MS system. LC with electrospray ionization and tandem MS operating in the multiple reaction monitoring mode provide high sensitivity and selectivity for trace analysis. The LODs were 0.10 and 0.54 ng/mL, and the LOQs were 0.20 and 1.35 ng/mL for BPS and BPA, respectively. The developed procedures were evaluated in terms for material collection obtained from women (inhabitants of Lublin, Poland). In 20 samples, bisphenol residues were detected at concentrations from 0.09 to 11.56 ng/mL.

Abstract
The study focused on the application of high-resolution mass spectrometry (HRMS) to postmortem toxicological analysis. Fast and simple sample preparation involved precipitation with acetonitrile, removal of phospholipids using special columns and filtration. Qualitative and quantitative analyses were performed using ultra-performance liquid chromatography coupled with quadrupole time-of–flight mass spectrometry. The method was validated by determining the limit of quantification, precision, recovery and matrix effect. The use of a high-resolution spectrometer allowed us to determine the precise masses of the fragments of interest and to suggest the fragmentation pathway of baclofen. The usefulness, effectiveness and assets of the procedure were confirmed by an authentic case of a 25-year-old woman fatally intoxicated with baclofen who was found dead in her apartment. Toxicological analysis of postmortem blood samples demonstrated that the baclofen concentration was 30.7 μg/mL. In only one published case describing fatal baclofen intoxication were no other xenobiotics (that could interact with baclofen) found. To our knowledge, this is the first report dealing with analysis of baclofen by HRMS.

The aim of the study was to determine the dynamics of the post-mortem decrease in rectal and kidney temperature. The temperature was measured on both sites at the same time using a thermometer connected to a computer, under constant environmental conditions of the necropsy room. In these animals, a higher temperature in the kidneys persisted for the duration of the study. Comparative analysis between mean differences in kidney and rectal temperature in small and large dogs showed the greatest temperature amplitude in the group of small dogs, both for the kidney and the rectum. The greatest decrease in temperature, 1.2°C, was noted for the kidney in small dogs between 4 and 6 hours after death. Analysis of the dynamics of the decrease in kidney and rectal temperature for both weight groups combined, and the difference in temperature between the kidney and the rectum in the time intervals analysed showed that in the first two hours the difference between kidney and rectal temperature did not exceed 0.5°C. Two hours after death the difference in temperature between the two measurement sites was about 0.5°C after which time dropped below 0.5ºC.

Abstract
Chronic pancreatitis (CP) results in impairment of exocrine as well as endocrine functions and progressive fibrosis. Previous studies, have demonstrated the presence of renin-angiotensin system receptors within different pancreatic cells. The aim of the present study was to assess the effects of renin-angiotensin system (RAS) inhibitors on serum levels of fibrosis biomarkers (matrix metalloproteinase 2 and 9 (MMP-2, MMP-9), tissue inhibitor of MMP (TIMP- 1, TIMP-2), hyaluronic acid (HA)) and fasting glucose levels in patients with alcoholic CP. Seventy seven outpatients (mean age 43 years, 62 males) with diagnosed alcoholic CP were randomly enrolled into 5 study groups depending on the RAS inhibitors administered and their doses (2.5 or 5 mg and 12.5 or 25 mg for ramipril or losartan, respectively). Venous blood was sampled monthly for a period of one year to monitor serum drug levels. MMP-2, -9, TIMP-1, TIMP-2 and HA were measured with ELISA method on the onset and at the end of the study. Only forty five patients regularly participated in follow-up visits and completed the study. The fluctuations in serum HA levels observed among patients from the remaining groups also did not reach statistical significance. Serum MMP-2 levels (P = 0.06) and MMP-2/TIMP-1 ratio (P = 0.06) showed increasing tendency in the losartan 25 mg group. High doses of ramipril and losartan statistically significantly reduced fasting glucose levels. High doses of losartan can increase the MMP-2 activity in serum of alcoholic CP patients, which potentially is likely to affect turnover of extracellular matrix proteins within the pancreas. Moreover, high doses of both RAS inhibitors decrease the fasting glucose level.

Abstract
This report presents the application of ultra-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry with positive electrospray ionization, to determine ramipril in human plasma. First, the proteins in human plasma were precipitated using acetonitrile, then the supernatant was extracted by ethyl acetate at pH 3 and finally, the extract was analyzed using a UPLC-QTOF- MS system. The method was validated and the coefficient of determination (R2) was >0.999, the lower limit of quantification (LLOQ) was 0.5 ng mL(-1). Precision, recovery and stability were determined for three different concentrations of ramipril. RSD for this method ranged from 3.3 to 8.6%. The intra-day mean recovery was from 65.3 to 97.3%. In addition, the fragmentation of ramipril was studied. Due to high resolution of the spectrometer, it was possible to measure fragment masses accurately and determine their molecular and chemical formulas with high accuracy.

Abstract
BACKGROUND Almost all experimental studies evaluating interactions between antiepileptic and non-antiepileptic drugs are based on their single administration, whereas epileptic patients require chronic pharmacotherapy. Herein, we attempted to figure out whether single and repeated administration of topiramate leads to the same anticonvulsant and undesired effects. METHODS Experiments were conducted in the model of maximal electroshock in mice. Motor coordination was evaluated in the chimney test. Brain concentrations of topiramate were determined by high-performance liquid chromatography and triple quadrupole mass spectrometry. RESULTS The anticonvulsant activity of topiramate administered once or twice a day for 7 days did not significantly differ from the respective effect of topiramate given acutely in a single injection. However, calculating of 50% effective doses for topiramate applied in 14-days protocol (once or two times a day) was impossible. The antiepileptic administered at the dose range of 80-150 mg/kg did not offer protection in more than 50% of mice. This phenomenon cannot be attributed to pharmacokinetic events, because there were no significant differences between plasma and brain concentrations of topiramate after its acute and chronic administration. Topiramate (150 mg/kg) did not affect motor performance in mice. CONCLUSIONS Maximal electroshock in mice does not seem to be an appropriate seizure model to test anticonvulsant effects of chronic topiramate.

Abstract
In the course of hypothermia, biochemical changes occur that are associated with stimulation of protective thermogenic mechanisms as well as mobilization of internal energy resources mediated by the hormone system. The objective of the investigation was the assessment of validity of determinations of cortisol, cortisone and corticosterone as hypothermia markers in cases of fatal hypothermia combined with concomitant insobriety of the victims. The experimental group consisted of blood samples collected in the course of medico-legal autopsies of 23 hypothermia victims. The controls included blood samples originating from 34 victims of violent sudden deaths (deaths by hanging and traffic road accidents at the scene) and from ten individuals deceased after prolonged agony in consequence of post-traumatic subdural hematomas. In both groups, three subgroups were distinguished that included cases with ethanol levels within the following ranges: 0.0-0.99, 1.0-2.99 and ≥3.0‰. The comparison of determination results showed that irrespectively of blood ethanol concentration, cortisol, cortisone and corticosterone levels seen in hypothermia victims were significantly higher as compared to the controls (P<0.001).

Abstract
PURPOSE Acetone is the principal ketone body elevated in the ketogenic diet (KD), with demonstrated robust anticonvulsant properties across a variety of seizure tests and models of epilepsy. Because the majority of patients continue to receive antiepileptic drugs (AEDs) during KD treatment, interactions between acetone and AEDs may have important clinical implications. Therefore, we investigated whether acetone could affect the anticonvulsant activity and pharmacokinetic properties of several AEDs against maximal electroshock (MES)-induced seizures in mice. METHODS Effects of acetone given in subthreshold doses were tested on the anticonvulsant effects of carbamazepine (CBZ), lamotrigine (LTG), oxcarbazepine (OXC), phenobarbital (PB), phenytoin (PHT), topiramate (TPM) and valproate (VPA) against MES-induced seizures in mice. In addition, acute adverse effects of acetone-AEDs combinations were assessed in the chimney test (motor performance) and passive avoidance task (long-term memory). Pharmacokinetic interactions between acetone and AEDs were also studied in the mouse brain tissue. RESULTS Acetone (5 or 7.5 mmol/kg, intraperitoneally [i.p.]) enhanced the anticonvulsant activity of CBZ, LTG, PB, and VPA against MES-induced seizures; effects of OXC, PHT, and TPM were not changed. Acetone (7.5 mmol/kg) did not enhance the acute adverse-effect profiles of the studied AEDs. Acetone (5 or 7.5 mmol/kg, i.p.) did not affect total brain concentrations of the studied AEDs. In contrast, VPA, CBZ, LTG, OXC, and TPM significantly decreased the concentration of free acetone in the brain; PB and PHT had no effect. CONCLUSIONS Acetone enhances the anticonvulsant effects of several AEDs such as VPA, CBZ, LTG, and PB without affecting their pharmacokinetic and side-effect profiles.

Abstract
Our previous studies demonstrated the usefulness of screening determinations of acetone as an initial diagnostic criterion in deaths due to hypothermia, alcoholic ketoacidosis, diabetes mellitus, starvation and some poisonings. In alcoholemia, particularly in cases of prolonged ethanol consumption, the above-mentioned conditions may not result in acetonemia, despite marked concentrations of beta-hydroxybutyrate acid (beta-HBA). Therefore, for the purpose of the present study, the method of beta-HBA determination was modified using GC-MS-EI and applied to analyze 47 autopsy blood samples of individuals who died suddenly due to unknown causes. In 15 cases, the concentration of beta-HBA was higher than 1000 micromol/l; in six subjects from this group, the acetone concentration was lower than 250 micromol/l. In some cases, thus, the use of beta-HBA as an additional diagnostic criterion allows for explaining the pathomechanism of premortal metabolic disturbances.

Abstract
The rate of alcohol elimination is highly resistant to acceleration in vivo in well-nourished individuals. The acceleration of ethanol elimination may be achieved by providing the conditions in which the action of alcohol dehydrogenase is not delayed by the insufficiency of the oxidized NAD form. The aim of the study was to verify the theoretically assumed mechanism of accelerating alcohol elimination by administering excessive acetoacetate (Ac-Ac) in the experimental in vitro model. Ac-Ac forming the redox system with beta-hydroxybutyrate (beta-HBA) is the natural acceptor of excessive protons from ethanol oxidation. Ac-Ac and beta-HBA penetrate freely through the cell membranes and are easily assimilated energetic substrates. The examinations were performed using the hepatic homogenates (collected from the cadavers shortly after death) supplemented with ethanol and Ac-Ac. The ethanol levels were determined at 0, 15, 60, 90 and 150 min of the experiment. The findings showed that the equimolar addition of Ac-Ac resulted in a two- to three-fold increase in ethanol oxidation in hepatic homogenates. The biochemical system discussed above resembles the natural way of utilizing the excessive NADH, which is formed during ethanol combustion in chronic alcoholics. The results indicate that further investigations are necessary to assess the clinical importance of this metabolic system.

Abstract
The process of cooling is always associated with the depletion of energetic reserves and burning the ketone bodies covers the tissues' needs. Ethanol shows antiketonaemic effects changing the cellular redox potential, inhibiting beta-oxidation of fatty acids, stimulating the release of insulin and inhibiting the release of its antagonist. The aim of the study was to determine whether the cooling process of the organism in the presence of ethanol intoxication may be related to inhibition of the physiological mechanism of ketogenesis induced by hypothermia. The study involved the 67 autopsy cases from 1996 to 2002, in which the circumstances of death indicated the effects of overcooling. This was confirmed on the basis of the data from the Prosecutor's Offices. Then, the chromatograms of autopsy blood alcohol determinations were analyzed and the acetone levels recorded. The analysis supported the hypothesis that the severity of ketosis is inversely proportional to the blood ethanol concentration. Furthermore, it demonstrated that signs of prolonged cold exposure were less frequently observed in unsober persons (frostbites, gastric hemorrhages). Increased sensitivity of intoxicated individuals to cold may be related not only to the dilation of the peripheral vessels, inhibition of shivering thermogenesis caused by muscle relaxation, central nervous system depression and behavioral factors but also to the antiketonaemic effects of ethanol.

Abstract
The homogenates of the livers, lungs and brains collected from five different cadavers were placed in the desiccator filled with vapours of rubber glue solvents and the concentrations of toluene, acetone and 2-propanol were determined during the 28-day storage at +25, +4 and -20 degrees C. It was demonstrated that only freezing of the material stabilised the initial concentration of these three xenobiotics while cooling to +4 degrees C resulted in limited conversion of acetone to 2-propanol and additionally reduced the biodegradation of toluene in the brain homogenates. Moreover, it was showed that at +25 degrees C the loss of acetone was almost equimolarly balanced by the 2-propanol increase, which allowed to estimate the initial concentration of acetone with the mean error of about 10%.

Abstract
The purpose of the study was to determine whether the postmortem diffusion of carbon monoxide (CO) significantly affected the results of carboxyhemoglobin (COHb) and carboxymyoglobin (COMb) determinations. The musculocutaneous and muscular specimens collected from adult cadavers were used. The specimens were treated with CO for 24 h at room temperature. COHb and COMb were determined using gas chromatography. It was demonstrated that the skin substantially limited the diffusion of CO which slightly penetrated only the superficial layers of the muscle and did not change the blood level of COHb in the 4.5-cm layer of the muscle located underneath. The CO diffusion through the superficially charred and thermally coagulated muscle did not differ from that observed in the intact integuments. On the other hand, the membrane of the skin completely deprived of the adipose layer was not the barrier to moderate diffusion into the blood layer situated below. Thus, in charred corpses the results pf COHb and COMb determinations in the material collected under the layer of charred and coagulated tissues enable us to determine whether the victim was alive at the moment of the outbreak.

Abstract
The paper presents the results of studies concerning the effects of four cyclic ketones, i.e. cyclopentanone (Pen), cyclohexanone (Hex), cycloheptanone (Hep) and cyclooctanone (Oct) on metabolism of ethanol (EtOH) in vitro. The fraction S9 (supernatant with the removed mitochondria) was used obtained from homogenized rat livers. An increase in reduced nicotinamide adenine dinucleotide (NADH) was examined spectrophotometrically (at 340 nm) while the substrate disappearance and metabolite increase were determined using head-space gas chromatography. The addition of cyclic ketones statistically significantly affected a decrease in the A(340) level, particularly during co-metabolism of EtOH and Hex. The EtOH loss was significantly higher (than the loss observed during metabolism of EtOH alone) only in EtOH-Hex and EtOH-Hep systems, which may be explained by the fact that reoxidation of NADH to NAD+ is quicker in these systems than dissociation of the alcohol dehydrogenase (ADH)-NADH complex.

Abstract
Presently available possibilities of macro- and microscopic diagnosis of death from hypothermia are very limited as the changes observed are either weakly specific (ecchymoses in the mucous membrane of the stomach, histological features of haemorrhagic pancreatic necrosis, cardiomyocyte necrosis or decreased content of glycogen in hepatocytes) or represent only local action of low temperatures (frostbites, violet patches in the region of knees and elbows, red livores) and they may not be present in cases of death from cooling at environmental temperature close to zero or higher. The study evaluated the usefulness of acetoacetic acid (Ac-Ac), beta-hydroxybutyric acid (beta-HBA) and acetone determinations in blood, urine and vitreous humour for diagnosis of death from hypothermia. These three substances called ketone bodies, are easily assimilated energetic substrates that get oxidized preferentially before glucose and fatty acids. In hypoglycaemia (also hypothermia-induced one), the tissues dependent on glucose (e.g. the brain) cover most of their energetic needs from oxidation of these compounds. The analysis of 16 cases of death in circumstances suggesting hypothermia (mainly of the alcohol abusers) showed that the degree of ketosis was inversely proportional to the blood ethanol concentration. This relation may result from stimulation of insulin release and a decrease in the release of its antagonists by ethanol, as well as from inhibition of free fatty acid (FFA) beta-oxidation due to increase in the NADH/NAD ratio. So, the antiketonaemic effects of ethanol (together with its influence on the dilatation of the peripheral vessels and inhibition of shivering thermogenesis by muscle relaxation), explain increased sensitivity of intoxicated persons to low temperatures.

We evaluated the protective activity (expressed as ED50 values in mg/kg of phenobarbital (PB, 120 min before testing) and valproate (30 min) alone or combined with caffeine in male mice with seizures induced by maximal electroshock (MES). Both antiepileptic drugs (AEDs) were administered by intraperitoneal (i.p.) injection in a single dose to mice receiving intraperitoneal caffeine either in a single dose 30 min before the test or as pretreatment every 12 h for 3 and 14 days. In addition, we determined the ED50 values of the AEDs 24 and 72 h after 14-day treatment with caffeine. Finally, we studied the influence of a challenge dose of caffeine, injected in mice 24 and 72 h after 14 days of treatment with caffeine, on the protective activity of PB or VPA. Caffeine in a single dose of 23.1 mg/kg reduced the anticonvulsant effect of PB. Its protective activity was further impaired after 3 and 14 days of caffeine treatment. The ED50 for VPA was significantly increased both by the single dose of caffeine and by chronic treatment. The anticonvulsant activity of PB and VPA measured 24 and 72 h after 14-day treatment with caffeine did not differ from control values, but a challenge dose of caffeine injected 24 or 72 h after daily injections for 14 days resulted in a significant reduction in the protective activity of both AEDs. Measurement of the total plasma levels of caffeine, VPA, and PB did not suggest pharmacokinetic interactions as an explanation for our results. Our results indicate that chronic caffeine exposure may progressively reduce the antiepileptic potency of VPA and PB.
