Fungal root endophyte associations of plants endemic to the Pamir Alay Mountains of Central Asia.

2011

The fungal root endophyte associations of 16 species from 12 families of plants endemic to the Pamir Alay Mountains of Central Asia are presented. The plants and soil samples were collected in Zeravshan and Hissar ranges within the central Pamir Alay mountain system. Colonization by arbuscular mycorrhizal fungi (AMF) was found in 15 plant species; in 8 species it was of the Arum type and in 4 of the Paris type, while 3 taxa revealed intermediate arbuscular mycorrhiza (AM) morphology. AMF colonization was found to be absent only in Matthiola integrifolia, the representative of the Brassicaceae family. The AM status and morphology are reported for the first time for all the species analyzed a…

GASTROINTESTINAL HELMINTHS OF THE DUSKY DOLPHIN, LAGENORHYNCHUS OBSCURUS (GRAY, 1828), OFF PATAGONIA, IN THE SOUTHWESTERN ATLANTIC

1999

The stomachs and intestines of 23 dusky dolphins incidentally caught in a trawl fishery off Patagonia were surveyed for helminths. All the dolphins were parasitized, with a total of 3,936 helminth individuals. Only five species occurred, of which three were common (prevalence ± 10%): Anisakis simplex, Braunina cordiformis and Hadwenius sp. A. simplex was present in all the dolphins and showed the highest abundance and mean intensity (104.9 individuals/infected host). B. cordiformis was next most common (87%), and Hadwenius sp. third (52.2%). A. simplex was found mostly in the stomach (94.8%), B. cordiformis in the duodenal ampulla (51.4%), and Hadwenius sp. in the stomach (64.5%). The rare …

Boat traffic in Lampedusa waters (Strait of Sicily, Mediterranean Sea) and its relation to the coastal distribution of common bottlenose dolphin (Tur…

2010

The volume of boat traffic and its potential connection to the coastal distribution of the common bottlenose dolphin (Tursiops truncatus) was evaluated off Lampedusa Island (Strait of Sicily). From July to September 2006 daily surveys were carried out at eight sites along the coast, three times a day, to assess the number, type, and size of boats moving, fishing, or stationed in Lampedusa waters. The study area was divided into four geographic areas: northwest, northeast, southwest, and southeast. Data were analyzed to determine the difference in the number of boats among the areas, sampling months, and times of day. The presence of dolphins was monitored by standardized land-based observat…

Investigations on the phosphoenolpyruvate carboxylase activity of spruce needles relative to the occurrence of novel forest decline

1991

Summary Investigations were carried out on phosphoenolpyruvate carboxylase (PEPC) activity in needles of Norway spruce trees [ Picea abies (L.) Karst.] at two natural sites during the course of three vegetation periods. PEPC activity found in needles of damaged trees was considerably higher than in needles of undamaged trees. Annual average figures varied up to 100%. The positive correlation between PEPC activity and the extent of damage of the investigated needles indicates a significant relationship between both parameters: the PEPC activity in spruce needles seems to be not only a qualitative, but also a quantitative indicator of the extent of damage. Higher PEPC activity in needles of d…

Enzym-histochemische Studien am cervicalen Dr�senfeld des Uterus

1972

Durch enzym-histochemische Untersuchungen an Cervices soll Einblick in den Stoffwechsel des cervicalen Drusenfeldes gewonnen werden. Hierfur wurden insbesondere die Enzyme des Glucosestoffwechsels, der Fettsaureoxydation, des Pentosephosphatstoffwechsels, des Citronensaurecyclus sowie des NADH- und NADPH-Diaphorese-Systems und des Aminosaurestoffwechsels untersucht. Die einheitliche Nachweistechnik erlaubt in Form eines Art Screening-Tests eine Information uber die vorhandenen Aktivitaten der einzelnen Enzyme, wobei — abgesehen von einem Enzym des Glucosestoffwechsels, namlich der Alkoholdehydrogenase und des Aminosaurestoffwechsels, der Glutamatdehydrogenase — alle Fermente nachgewiesen we…

Causalità e colpa nell'esposizione dei lavoratori alle polveri di amianto fra "caos" e "logos"

2009

L’esperienza giurisprudenziale in materia di esposizione dei lavoratori alle polveri di amianto costituisce un banco di prova particolarmente utile per una rigorosa verifica delle elaborazioni teoriche concernenti la causalità e la colpa. Sul versante della causalità, al progressivo abbandono di posizioni incentrate sull’eccessiva enfatizzazione del quantum di probabilità statistica ha fatto seguito la graduale ammissione del criterio della credibilità razionale. Tale importante mutamento di approccio non è stato tuttavia sufficiente a eliminare in modo radicale la tendenza della giurisprudenza a confondere il profilo della spiegazione causale/naturalistica con il profilo dell’imputazione n…

Rigid biobased polycarbonates with good processability based on a spirocyclic diol derived from citric acid

2020

Introducing biobased polymers from renewable sources for use as high-performance thermoplastics with high demands on mechanical rigidity, transparency, thermal stability, as well as good processability, is a significant challenge. In the present work we have designed and prepared a rigid biobased bis-spirocylic diol by di-cycloketalization of a bicyclic diketone (cis-bicyclo[3.3.0]octane-3,7-dione, obtained from citric acid) using trimethylolpropane. This spiro-diol monomer has two reactive primary hydroxyl groups and the synthesis from inexpensive biobased starting materials is straightforward and readily upscalable, involving no chromatographic purification. In order to explore the useful…

Effect of natural antioxidants and modified atmosphere packaging in preventing lipid oxidation and increasing the shelf-life of common dolphinfish (C…

2015

We investigated the effects of natural antioxidants and modified atmosphere packaging (MAP) on the quality and shelf-life of Coryphaena hippurus (common dolphinfish) fillets. Fillets of the control group (CO) were simply placed on trays and not sealed. Fillets of the second group (MAP) were preserved in modified atmosphere (45% CO2, 50% N2, 5% O2), and fillets of the third group (MAP-AOX) were preserved by combining natural antioxidants from halophytes with modified atmosphere. All samples were stored in a refrigerator at 1 ± 0.5 C for 18 days. Analyses were conducted at T0 and after 3, 6, 12, 15 and 18 days of storage. According to sensory tests and colour analyses, the fillets in the MAP …
