RESEARCH ON CLOVER CROP MIXED WITH PERENNIAL GRASS FORAGE IN THE CENTRAL AREA OF OLTENIA
In the central area of Oltenia, Trifolium pretense specie can be used as perennial legume mixed with Dactylis glomerata or Lolium hybridum for temporary meadow. Between these two experimeted mixtures the best results were obtained by Trifolium pratense and Lolium hybridum that realized 6.25 t/ha dry matter as an average value on three experimental years. The meadow including 80 % Dactylis glomerata + 20% Trifolium pratense without fertlization, lead to the lowest forrage yiled, while the yield obtained by the mixture 40 % Lolium hybridum + 60% Trifolium pratense was much higher
THE INCREASING OF FODDER YIELD IN THE CENTER PART OF OLTENIA FOR SUSTAINABLE DEVELOPMENT OF LIVESTOCK
The environmental conditions from experimental area (ARDS Simnic, Dolj, Romania) offers favorable conditions for temporary meadows that give increased yield of quality feed. The proper fertilizing schedule combined with a good management contributes to a long permanence of temporary pasture
The anatomy of a horizontally impacted maxillary wisdom tooth
A completely horizontally impacted upper third molar was revealed after routine
dissection of a 62-year-old human cadaver of a Caucasian male. The molar
was penetrating into the maxillary sinus and there was antral dehiscence of its
bony alveolus. The bony alveolus was immediately in front of the greater palatine
canal contents, and the bottom of the alveolus was dehiscent towards
the greater palatine foramen. Within the greater palatine canal and foramen
the greater palatine artery was duplicated and the nerve was found. Such antral
relations of an impacted upper third molar predispose to oroantral communications
if extraction is performed, while the close neurovascular relations
represent a risk factor for postextractional haemorrhage and neurosensory disturbances
and must be borne in mind when deciding on or performing the
extraction. (Folia Morphol 2008: 67: 154–156
THE EXPERIMENTAL RESULTS REGARDING THE INFLUENCE OF THE COMPOST AND OF THE AMENDAMENTS TO THE TEMPORARY MEADOWS FROM SCDA SIMNIC
Both the simple mixture of graminaceae and pulverize and the complex react very weel both to the organic fertilization and the chimical one with nitrogen.The amount of the crop obtained in the mictures with organic fertilization, with oxidat between 1,3 – 2,1 t/m d.s. at the simple mixture and 1,8 – 2,6 t/ha d.s. in the case of the complex mixture of nitrogen. The nitrogenous, too has substantially contributed to the encreasing of the crop, ensuaring a growth of over 3,6 t/ha d.s. (N120) at the simple mixture, respectively over 5,4 t/ha d.s. (N120) at the complex mixture
RESEARCHING RESULTS ON THE FERTILIZER APPLYING ON SOWN PASTURES ON LUVISOIL FROM ARDS SIMNIC
The sown pastures that are made of valuable grasses and leguminous fodder species have a high productive potential which can only be capitalized byproper fertilization. The mineral fertilizers are applied on a large scale due to their easy absorbtion by plants because they are soluble and immediate effect. Thenitrogen fertilizers applied on several rates substantially contributes to theobtaining of high harvests of fodder of good quality ensuring a better rescheduling of production
RESEARCHES ON THE APPLYING TIME OF FERTILIZERS AND THEIR TYPE ON SOWN PASTURES FROM CENTRAL AREA OF OLTENIA
Proper use of fertilizers on pastures assumes the detailed knowing of technical aspects related with the type of the fertilizer, the combination, the rate, the splitting, the time of applying, all these things making the object of extensive researches. Regarding the chemical fertilization, on sown pastures there can be used, both, simple fertilizers (ammonium nitrate, nitrocalcar, superphosphate, potassium salt, etc.) and complex ones in different formulas
In-stent restenosis in the drug eluting stent assayed by optical coherence tomography
Hospital of Holy Pope Giovanni XXIII, Bergamo, Italy, Department of Interventional Cardiology, Institute of Cardiology, Chisinau, the Republic of MoldovaBackground: In order to study the mechanisms and morphological aspects of the in-stent restenosis (ISR) have been evaluated restenosis lesions referred to drug eluting stent (DES) of the first generation using optical coherence tomography technique (OCT). Material and methods: The study underwent 39 patients with ISR induced recurrent angina or acute coronary syndrome including 66 stents from which were: 44 stents (28 patients) of the first generation of DES (19 – Cypher TM and 23 – Taxus®), and 22 stents (11 patients) of the second DES generation (9 Xience TM 2 Promus TM), 10 ZES (Resolute TM), and one stent Nobori TM. Has been made quantitative and morphological analysis of tissue pattern of ISR using the following OCT criteria: 1) morphologically homogenous neointima; 2)morphologically heterogeneous neointima; and 3) neoatherosclerosis. Results: It has been established that in the first generation of DES morphological homogenous pattern was present in both ISR developed after 1 year and later. However, the optical aspect with heterogeneous presentation had a prevalence decline in dynamics. The heterogeneous model had a higher prevalence in actual generation of DES in both incipient (< 1 year) and late presentation. Conclusions: The phenomenon of neoatherosclerosis has presented a significantly less frequency in the late restenosis of actual generation of DES. Our results suggest that restenosis phenomenon in actual generation of DES has a different morphological and evolution pattern in time in comparison with ISR of the first generation of DES
Intracoronary optical coherence tomography
The cardiovascular departments of the hospital of Holy Pope Giovanni XXIII in Bergamo, Italy and of the Institute of Cardiology in Chisinau,
the Republic of Moldova have a fruitful history of collaboration in the field of interventional cardiology and intracoronary imaging in particular. We
have recently expanded our collaboration by adding the method of Optical Coherence Tomography (OCT) into the armamentarium of imaging in the
catheterization laboratory. OCT is an innovative, real time, tomographic imaging modality able to visualize tissues at microstructure level. It delivers
the rays of near-infrared light through the wall of the coronary artery using small diameter optical fibres. The light that illuminates the vessel is absorbed
and backscattered or reflected by the structures of the tissues with different degrees of density, thus creating an image with an axial resolution of 10-20
µm. This technology allows acquiring high definition images of long segments of coronaries for a few seconds. For the time being, OCT is mainly used
in the researches, providing insights into the pathophysiology of the atherosclerotic plaque and the vascular response to stenting. It also has a potential
for clinical application, such as pre-interventional evaluation of coronary arteries, procedures guidance and follow-up assessment of vascular healing
after the stent implantation. A joined database has been created by the two institutions in an effort to study in vivo the morphology of the coronary
arteries in different pathologies. This review is focused on the potential fields of application of OCT in different clinical and scientific institutions
