AB  - Background: The cannabis plant or marijuana has been used since ancient times for different purposes. An increase in the content of THC in cannabis has been observed worldwide, whereas the CBD content is dropping. This study’s main goal was to categorize marijuana suspected policies’ seizures (MSPS) based on the cannabinoid component concentrations concerning their potency and age. Methods: The samples were MSPS seized in southeast Serbia from April 2019 to April 2020. The cannabinoid content was determined using gas chromatography with mass spectrometry. Descriptive statistics were performed using Linux LibreOffice Calc. Results: All of the samples had a THC content higher than 0.3%, thus classifying the samples as marijuana according to the Serbian Law on Psychoactive Controlled Substances. The highest concentration of THC was 16.10%, while the lowest was 4.90%. The highest average concentration of THC (12.39%) was found in the buds. Only 11.81% of the samples had a CBD concentration higher than 1%, making all other marijuana samples extremely psychoactive. Most of the samples were older than 2 years, according to the calculated CBN/THC ratio. Conclusion: Our results confirm trends regarding the dominance of THC content in contemporary cannabis worldwide. It is necessary to monitor trends of cannabis potency in Serbia continuously because of its location.

AB  - Background: Anterior mitral leaflet prolapse repair is a highly effective procedure, but despite excellent operative results still has an inferior long‐term durability when compared to posterior leaflet repair. Methods: We analysed mitral repair durability in 74 consecutive patients operated for anterior leaflet prolapse between 2010 and 2021. Their pre‐ and postoperative clinical, echocardiographic data and repair durability as well, were compared with 74 randomly assigned posterior leaflet prolapse patients who underwent valve repair during the same period. Results: While groups were of similar age, patients with anterior leaflet prolapse had an inferior preoperative status in terms of functional reserve, atrial fibrillation, operative risk, ejection fraction and had more dilated left heart chambers as well. 1, 5, and 10‐year freedom from repair failure was 87.1 ± 4.6%, 79.8 ± 6.5% and 50.7 ± 12.5% in the anterior, and 98.5 ± 1.5% respectively in the posterior leaflet group. Atrial fibrilation (hazard ratio [HR] 5.365; 95%; confidence interval [CI] 1.093–26.324 p = .038) and left ventricle end‐systolic diameter (HR 1.160 95%; CI 1.037–1.299 p = .010) independently predicted anterior leaflet repair failure. Receiver Operating Curve analysis established left ventricle end‐systolic diameter ≤42 mm as a cut‐off value associated with improved anterior leaflet repair durability. Accordingly, 10‐year repair durability in a subset of patients, with preserved left ventricle end‐systolic diameter (≤42 mm) was 86.4 ± 7.8%. Conclusion: Better long‐term repair durability in patients with anterior mitral leaflet prolapse and preserved sinus rhytm and left‐ventricle diameters justifies early reconstructive approach.

AB  - Findings from epidemiological studies indicate that polyphenols, widespread in
human diet and with numerous biological activities, act cardioprotectively. Procyanidins are
subclass of polyphenols with high content in commonly consumed foods and beverages, such
as grapes, tea, chocolate, nuts and apples. Cardioprotective abilities of procyanidins, might, at
least partly, attribute to their vasodilator properties. Since exact mechanisms of procyanidin
B2-induced vasorelaxation are unknown, our study aimed to investigate relaxant effect of
procyanidin B2 on isolated human saphenous vein (HSV) and its underlying mechanisms.
Discarded segments of HSV were collected from patients undergoing bypass surgery and
studied in organ baths. Procyanidin B2 caused concentration-dependent relaxation of HSV
precontracted by phenylephrine. The relaxation was strongly affected by inhibitors of
NO/cGMP pathway, L-NAME, hydroxocobalamin and ODQ. Indomethacin, a cyclooxygenase
inhibitor, significantly reduced only relaxation produced by the highest concentrations of
procyanidin B2. Combination of apamin and TRAM-34, selective blockers of small- and
intermediate-conductance Ca 2+ -activated K+ (KCa ) channels (SKCa and IK Ca ), in the presence of
L-NAME and indomethacin, did not additionally affect procyanidin B2-induced relaxation.
Additionally, relaxation induced by procyanidin B2 was partially attenuated by 4-
aminopyridine, predominant blocker of voltage-gated K+ (KV) channels, significantly
inhibited by glibenclamide, selective ATP-sensitive K+ (KATP) channels inhibitor, and almost
abolished by iberiotoxin, highly selective blocker of large-conductance KCa (BKCa ). Our results
revealed that procyanidin B2 acts as a potent vasodilator on isolated human venous graft.
Mechanism of this relaxation of HSV probably involves stimulation of NO production, as well

AB  - Hydrogen sulfide (H2S) represents the third and the youngest member of the gaseous transmitters family. The dominant effect of H2S on isolated vessels is vasodilation. As the mechanism of H2S-induced relaxation in human vessels remains unclear, the present study aimed to investigate the effects of H2S donor, sodium hydrosulfide (NaHS), on isolated human saphenous vein (HSV) and to determine the mechanism of action. Our results showed that NaHS (1 µM–3 mM) induced a concentration-dependent relaxation of endothelium-intact HSV rings pre-contracted by phenylephrine. Pre-treatment with L-NAME, ODQ and KT5823 significantly inhibited NaHS-induced relaxation, while indomethacin induced partial inhibition. Among K+ channel blockers, the combination of apamin and TRAM-34 significantly affected the relaxation produced by NaHS, while iberiotoxin and glibenclamide only reduced maximal relaxation of HSV. NaHS partially relaxed endothelium-intact rings pre-contracted by high K+, as well as phenylephrine-contracted rings in the presence of nifedipine. Additionally, the incubation of HSV rings with NaHS increased NO production. These results demonstrate that NaHS produces the concentration- and endothelium-dependent relaxation of isolated HSV. Vasorelaxation to NaHS probably involves activation of NO/cGMP/PKG pathway and partially prostacyclin. In addition, different K+ channels subtypes, especially SKCa and IKCa, as well as BKCa and KATP channels in high concentrations of NaHS, probably participate in the NaHS-induced vasorelaxation.

AB  - Cardioprotective abilities of procyanidins, might, at least in part, attribute to their vasodilator properties. The present study was undertaken to assess the vasorelaxant effect of procyanidin B2 on isolated human saphenous vein (HSV) and its underlying mechanisms. Procyanidin B2 relaxed phenylephrine-induced contraction of HSV rings in concentration-dependent manner. The relaxation was dependent on the presence of endothelium and was strongly affected by l-NAME, hydroxocobalamin or ODQ, the inhibitors of NO/cGMP pathway. Indomethacin significantly affected only the relaxation produced by the highest concentrations of procyanidin B2. Apamin and TRAM-34 combination, in the presence of l-NAME and indomethacin, did not additionally decreased procyanidin B2-induced relaxation. In the presence of K+ channel blockers, relaxation induced by procyanidin B2 was partially attenuated by 4-aminopyridine, significantly inhibited by glibenclamide and almost abolished by iberiotoxin. Procyanidin B2 also relaxed the contractions induced by phenylephrine or caffeine in Ca2+-free solution. Finally, nifedipine slightly, while thapsigargin strongly antagonized HSV relaxation. Our results indicate that procyanidin B2 induces endothelium-dependent relaxation of HSV, which results primarily from stimulation of NO production, as well K+ channels opening, especially BKCa, and partially KATP and KV.

abstract = "Cardioprotective abilities of procyanidins, might, at least in part, attribute to their vasodilator properties. The present study was undertaken to assess the vasorelaxant effect of procyanidin B2 on isolated human saphenous vein (HSV) and its underlying mechanisms. Procyanidin B2 relaxed phenylephrine-induced contraction of HSV rings in concentration-dependent manner. The relaxation was dependent on the presence of endothelium and was strongly affected by l-NAME, hydroxocobalamin or ODQ, the inhibitors of NO/cGMP pathway. Indomethacin significantly affected only the relaxation produced by the highest concentrations of procyanidin B2. Apamin and TRAM-34 combination, in the presence of l-NAME and indomethacin, did not additionally decreased procyanidin B2-induced relaxation. In the presence of K+ channel blockers, relaxation induced by procyanidin B2 was partially attenuated by 4-aminopyridine, significantly inhibited by glibenclamide and almost abolished by iberiotoxin. Procyanidin B2 also relaxed the contractions induced by phenylephrine or caffeine in Ca2+-free solution. Finally, nifedipine slightly, while thapsigargin strongly antagonized HSV relaxation. Our results indicate that procyanidin B2 induces endothelium-dependent relaxation of HSV, which results primarily from stimulation of NO production, as well K+ channels opening, especially BKCa, and partially KATP and KV. Regulation of the intracellular Ca2+ release and inhibition of Ca2+ influx probably contr",
