V okviru genske banke zdravilnih in aromatičnih rastlin pri Biotehniški fakulteti Univerze v Ljubljani (BFUNI) poteka ohranjanje genskih virov in situ, ex situ in in vitro. Pri in situ ohranjanju je ...bistveno popisovanje gostote populacij na naravnih rastiščih zdravilnih rastlin, pri čemer lokacije označimo z geografskimi koordinatami in ovrednotimo z deskriptorji za kolekcioniranje, okoljskimi deskriptorji in vrstno specifičnimi deskriptorji. Metodologija vrednotenja naravnih populacij rastlinskih vrst in njihovih habitatov, osnovana na sistemu deskriptorjev, je harmonizirana v okviru držav članic programa ECPGR in SEEDNet. S pomočjo terenskih vzorčenj zdravilnih in aromatičnih rastlin ter obdelave zbranih podatkov s pomočjo informacijskega sistema MEDPLANT bo mogoče prikazati biodiverziteto med preučevanimi populacijami zdravilnih in aromatičnih rastlin, kar bo v pomoč končnim uporabnikom in eventuelno žlahtniteljem v prihodnosti. V okviru terenskega dela ocenjujemo pojavnost 10 izbranih rastlinskih vrst: skupina taksonov navadnega rmana (Achillea millefolium L. s. lat.), skupina taksonov pravega ranjaka (Anthyllis vulneraria L. s. lat.), navadna arnika (Arnica montana L.) – zavarovana (kategorija varovanja – C, O) in ranljiva vrsta (kategorija ogroženosti – V), pravi pelin (Artemisia absinthium L.), skupina taksonov rumenega svišča, košutnika (Gentiana lutea L. s. lat.) – zavarovana (kategorija varovanja – C) in ranljiva vrsta (kategorija ogroženosti – V) (Uradni list RS 82/02, 46/04; 49/04; 110/04), šentjanževka (Hypericum perforatum L. s. lat.), navadna dobra misel (Origanum vulgare L. s. lat.), razkrečena rutica (Ruta divaricata Ten.), žajbelj (Salvia officinalis L.) in kraški šetraj (Satureja montana L. s. lat.).
Med drugim prinaša mehanizem za usklajevanje pogosto nasprotujočih si javnih interesov v prostoru, in sicer bo ob morebitni koliziji javnih interesov, pri kateri na strokovni ravni ni mogoče doseči ...usklajene rešitve, mnenje podajala novoustanovljena vladna komisija za prostorski razvoj, ki se bo posvetovala s prav tako novoustanovljenim prostorskim svetom kot posvetovalnim organom okoljskega ministrstva. Zakon poleg tega vpeljuje razvojne stopnje stavbnih zemljišč in njihovo evidentiranje. 2.2 Gradbeni zakon (GD) Gradbeni zakon med drugim prinaša novosti glede pridobivanja gradbenega dovoljenja, za katerega bo potrebna manj obsežna dokumentacija, del postopka bo tudi pridobivanje mnenj (sedanjih soglasij), s čimer naj bi se skrajšali postopki. Gradbeni zakon prinaša tudi možnost legalizacije neproblematičnih nedovoljenih gradenj: za objekte, ki so bili zgrajeni pred letom 1998, bo mogoče pridobiti dovoljenje za objekt daljšega obstoja, pri čemer bo moral lastnik med drugim plačati nadomestilo za degradacijo in uzurpacijo prostora. Sistem množičnega vrednotenja je prilagojen glede na dostopnost kakovostnih podatkov o nepremičninah, zakonski predlog prav tako vsebuje odpravo tistih pomanjkljivosti oziroma nedorečenosti sistema, ki sta jih zaznala ministrstvo za okolje in prostor (MOP) in geodetska uprava (GURS) pri dosedanjem opravljanju nalog zbiranja in vodenja podatkov o nepremičninah in nalog množičnega vrednotenja.
Myxomatous mitral valve degeneration (MMVD) is the most common naturally occurring heart disease in dogs. There is a lack of data on antioxidant status and oxidative damage in dogs with MMVD stage B1 ...according to the American College of Veterinary Internal Medicine (ACVIM B1). The aim of this study was to investigate antioxidant status (plasma vitamin E, lipid-standardized vitamin E (LS-VitE), antioxidant capacity of lipid-(ACL) and water-soluble antioxidants, whole blood glutathione peroxidase and erythrocyte superoxide dismutase), and lipid peroxidation malondialdehyde (MDA) in dogs with MMVD ACVIM B1. Serum cholesterol and triglyceride concentrations were measured to calculate LS-VitE. Fourteen dogs with MMVD ACVIM B1 and 12 control dogs were included in the study. Dogs with MMVD had significantly higher vitamin E, ACL, MDA, and cholesterol concentrations and significantly higher LS-VitE values than control dogs. No significant correlations between MDA and antioxidant parameters were determined in either group. In conclusion, oxidative damage to lipids is already present and the antioxidant status is altered but not depleted in dogs with MMVD ACVIM B1. The antioxidant response to increased oxidative damage consists mainly of the activation of fat-soluble antioxidants. Further research is needed to evaluate the efficacy and targets of early antioxidant supplementation to prevent or ameliorate oxidative stress and mitigate disease progression in dogs with early-stage MMVD.
Antioxidants located in both the hydrophilic and lipophilic compartments of plasma act as a defence system against reactive oxygen species (ROS). Excessive production of ROS during anaesthesia ...affects the antioxidant capacity of plasma and may result in oxidative stress. The aim of this study was to evaluate the antioxidant capacity of lipid- (ACL) and water-soluble (ACW) antioxidants in client-owned dogs diagnosed with periodontal disease and early-stage myxomatous mitral valve degeneration (MMVD) and anaesthetised for a dental procedure with propofol and sevoflurane or with propofol only.
Dogs with MMVD were anaesthetised with propofol and sevoflurane (MMVD/PS, n = 8) or with propofol only (MMVD/P, n = 10). Dogs with no evidence of MMVD (PS, n = 12) were anaesthetised with propofol and sevoflurane. Blood samples for determination of ACL and ACW were collected before and 5 min, 60 min and 6 h after induction to anaesthesia. In MMVD/PS dogs, ACL was significantly higher at all sampling times when compared to PS dogs. Compared to basal values, only anaesthesia maintained with propofol significantly increased ACL at 60 min in dogs with MMVD. In MMVD/P dogs, ACW increased after induction to anaesthesia and remained elevated up to 6 h after anaesthesia. Compared to basal values, anaesthesia maintained with sevoflurane significantly increased ACW only at 60 min in both dogs with and without MMVD. The only difference between propofol and propofol/sevoflurane anaesthesia in dogs with MMVD was significantly higher ACW at 60 min after induction to anaesthesia in the propofol group.
Regarding antioxidant capacity, propofol could be a better choice than sevoflurane for anaesthesia of dogs with early-stage MMVD, although further studies are necessary to clarify the advantage of this antioxidant capacity.

The aim of this study was to investigate the effects of total intravenous anaesthesia with propofol and anaesthesia induced with propofol and maintained with sevoflurane on oxidative stress ...parameters in dogs with early-stage myxomatous mitral valve degeneration (MMVD). Sixteen client-owned dogs with early stage MMVD that required periodontal treatment were included in the study. After induction with propofol, anaesthesia was maintained with propofol (group P) or sevoflurane (group PS). Blood samples for determination of vitamin E, superoxide dismutase, glutathione peroxidase and malondialdehyde were collected before premedication, 5 and 60 minutes and 6 hours after induction to anaesthesia. There were no significant differences between groups in any of the oxidative stress parameters at each sampling time. Compared to basal values, vitamin E concentration decreased significantly during anaesthesia in both groups and glutathione peroxidase activity increased 60 minutes after induction to anaesthesia in PS group. Anaesthesia with propofol or with propofol and sevoflurane did not have any significant impact on oxidative stress parameters in dogs with early stage MMVD. In terms of oxidative stress, both protocols may be equally safely used in dogs with early stage MMVD.
The first clinical studies on the use of electrochemotherapy to treat liver tumours that were not amenable to surgery or thermal ablation techniques have recently been published. However, there is ...still a lack of data on the effects of electrochemotherapy on normal liver tissue. Therefore, we designed a translational animal model study to test whether electrochemotherapy with bleomycin causes clinically significant damage to normal liver tissue, with emphasis on large blood vessels and bile ducts. We performed electrochemotherapy with bleomycin or delivered electric pulses alone using a potentially risky treatment strategy in eight pigs. Two and seven days after treatment, livers were explanted, and histological analysis was performed. Blood samples were collected before treatment and again before euthanasia to evaluate blood biomarkers of liver function and systemic inflammatory response. We found no thrombosis or other clinically significant damage to large blood vessels and bile ducts in the liver. No clinical or laboratory findings suggested impaired liver function or systemic inflammatory response. Electrochemotherapy with bleomycin does not cause clinically significant damage to normal liver tissue. Our study provides further evidence that electrochemotherapy with bleomycin is safe for treatment of patients with tumours near large blood vessels in the liver.
