Correlations between the adaptive capacity in Bucovina of Limousine cows and the nutritional quality of the milk
Get PDFThe Limousine breed is spread on all continents in 64 countries, and Romania will be the 65th country in which it is
trying to adapt this breed of cattle. Limousine is currently ranked No. 1 in England and is highly regarded in other
countries, including France, No. 2, Canada, No. 2, Italy, and the United States. 3rd place. The main objective of this
project is to observe the adaptability of the Limousine breed to the geo-meteorological conditions recorded in northern
Romania, the Bukovina region. The aim of the paper is to evaluate from a nutritional qualitative point of view the raw
milk obtained from this breed. The investigations were carried out to establish the degree of freshness, integrity and we
monitored some physical-chemical and hygienic parameters of the raw material milk. Sampling was done directly from
the collection vessels after milking and filtration mainly in the hot season, and their processing was done in the Food
Control Laboratory of the Faculty of Veterinary Medicine Iasi, where a number of 38 milk samples were processed.
Following the analysis of the samples, a number of 8 samples were inadequate in terms of organoleptic examination and
integrity. Deviations from the organoleptic characteristics of the parameters of appearance, color, smell, and taste
represented a percentage of 21.05%. The determinations of the Physico-chemical parameters were classified as
inappropriate a number of 10 samples which represents a percentage of 26.31% of the total samples collected

No full textEvaluation of ketamine - droperidol anesthesia in dogs
Get PDFThe main objective of this study was to observe the influence of anesthesia combined with ketamine and droperidol,
compared both in bolus administration and in continuous intravenous infusion, following the effects on cardiac and
respiratory function. The experiment was performed on 16 clinically healthy dogs that had previously been preanesthetized
with acepromazine intramuscularly at a dose of 0.5 mg / kg. The dogs were divided into two groups (A and
B). The group A (n = 8) was given the combination ketamine (8 mg / kg) / droperidol (1 mg / kg), intravenously, in a
bolus, through the cephalic vein, in a time interval of more than 30 seconds. Group B (n = 8) was given the same
combination and through the same vein, but in continuous infusion over a period of approximately 20 minutes.
Ketamine and droperidol were mixed in the same syringe shortly before bolus administration. The study was repeated in
6 dogs, using only acepromazine, 0.5 mg / kg, to evaluate the influence of the preanesthetic on the results obtained in
the 2 groups A (bolus) and B (infusion). The results of the study showed that the ketamine / droperidol combination
should be used with caution in dogs pre-anesthetized with acepromazine, but the effect of anesthesia combined with
ketamine and droperidol is better than that of anesthesia only with ketamine

Design, synthesis, and preliminary evaluation for Ti-Mo-Zr-Ta-Si alloys for potential implant applications
Get PDFConsidering the future trends of biomaterials, current studies are focused on the corrosion
resistance and the mechanical properties of new materials that need to be considered in the
process of strengthening alloys with additive non-toxic elements. Many kinds of titanium alloys with
different biocompatible elements (Mo, Si, Zr, etc.,) have been recently developed for their similar
properties with human bone. Four new different alloys were obtained and investigated regarding
their microstructure, mechanical, chemical, and biological behavior (in vitro and in vivo evaluation),
the alloys are as follows: Ti15Mo7Zr15Ta, Ti15Mo7Zr15Ta0.5Si, Ti15Mo7Zr15Ta0.75Si, and
Ti15Mo7Zr15Ta1Si. There were changes with the addition of the silicon element such as the hardness
and the modulus of elasticity increased. An MTT assay confirmed the in vitro cytocompatibility of
the prepared alloys
Mycosands: Fungal diversity and abundance in beach sand and recreational waters - Relevance to human health
Get PDFThe goal ofmost studies published on sand contaminants is to gather and discuss knowledge to avoid faecal contamination
of water by run-offs and tide-retractions. Other life forms in the sand, however, are seldom studied
but always pointed out as relevant. The Mycosands initiative was created to generate data on fungi in beach
sands and waters, of both coastal and freshwater inland bathing sites. A team of medical mycologists and
water quality specialists explored the sand culturable mycobiota of 91 bathing sites, and water of 67 of these,
spanning fromthe Atlantic to the EasternMediterranean coasts, including the Italian lakes and the Adriatic, Baltic,
and Black Seas. Sydney (Australia) was also included in the study. Thirteen countries took part in the initiative.
The present study considered several fungal parameters (all fungi, several species of the genus Aspergillus and
Candida and the genera themselves, plus other yeasts, allergenic fungi, dematiaceous fungi and dermatophytes).
The study considered four variables that the team expected would influence the results of the analytical parameters,
such as coast or inland location, urban and non-urban sites, period of the year, geographical proximity and
type of sediment. The genera most frequently found were Aspergillus spp., Candida spp., Fusarium spp. and Cryptococcus
spp. both in sand and in water. A site-blind median was found to be 89 Colony-Forming Units (CFU) of
fungi per gram of sand in coastal and inland freshwaters, with variability between 0 and 6400 CFU/g. For freshwater
sites, that number was 201.7 CFU/g (0, 6400 CFU/g (p = 0.01)) and for coastal sites was 76.7 CFU/g (0,
3497.5 CFU/g). For coastalwaters and allwaters, themedianwas 0 CFU/ml (0, 1592 CFU/ml) and for freshwaters
6.7 (0, 310.0) CFU/ml (p < 0.001). The results advocate that beaches should bemonitored for fungi for safer use
and better management
Assessment of the effects of Si addition to a new TiMoZrTa system
Get PDFTi-based alloys are widely used in medical applications. When implant devices are used
to reconstruct disordered bone, prevent bone resorption and enhance good bone remodeling, the
Young’s modulus of implants should be close to that of the bone. To satisfy this requirement, many
titanium alloys with different biocompatible elements (Zr, Ta, Mo, Si etc.) interact well with adjacent
bone tissues, promoting an adequate osseointegration. Four new different alloys were obtained and
investigated regarding their microstructure, mechanical, chemical and biological behavior (in vitro
and in vivo evaluation), as follows: Ti20Mo7Zr15Ta, Ti20Mo7Zr15Ta0.5Si, Ti20Mo7Zr15Ta0.75Si and
Ti20Mo7Zr15TaSi. 60 days after implantation, both in control and experimental rabbits, at the level of
implantation gap and into the periimplant area were found the mesenchymal stem cells which differentiate into osteoblasts, then osteocytes and osteoclasts which are involved in the new bone synthesis and remodeling, the periimplant fibrous capsule being continued by newly spongy bone tissue, showing a good osseointegration of alloys. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay confirmed the in vitro cytocompatibility of the prepared alloys

and stability. They still have dominance of the bioecology and pathology of the animals still incompletely
elucidated and, respectively, controlled. The following species of wild animals of hunting interest were studied: deer
(Dama dama), wild boar (Sus scrofa ferus) and fox (Canis vulpes) and the diseases studied are: African swine fever in
wild boars, specific diseases of deers and Rabies in foxes. The study provides support for preventive management
actions aimed at protecting the public health and the economy
Conținutul metalelor grele în solurile ariilor naturale protejate de stat din regiunea de sud-est a Republicii Moldova
Get PDFHeavy metal (HM) content has been assessed in soils within 10 state protected natural areas (SPNA). The soil samples were collected from the soil layer 0-20 which is in direct relation to all biotic (edaphic and bio-indicatory plant organisms, soil microorganisms) and abiotic (atmospheric and wind deposits, physical-chemical processes, etc.) components responsible for the HM circuit within the ecosystems.
Evaluated on the basis of the grading scale of soils of the Republic of Moldova, (Кирилюк, 2006), the content of HM (Zn, Cu, Ni, Co) analysed, for the soil layer studied, was included in the categories of very low - high levels. In the evaluated soil layer, no cases of studied HM pollution were recorded. In some cases, however, there are trends in the accumulation of Zn and Cu, but their contents do not exceed the alert threshold (AT) values (tab. 1).
Both for APNA and for other terrestrial ecosystems, increased Cu and sometimes Zn content in environmental components are characteristic, as a result of the intensive processing of surrounding agricultural land and forests with phytosanitary products containing Cu and Zn.
After Adriano (1986), copper and zinc fall into the category of microelements with a biologically important role for forest ecosystems, deficiencies (100 mg/kg), can cause reduction of root and shoot growth, inhibition of enzymes, risks that in the case of ecosystems investigated are not attested.
In the case of the intervention threshold (IT), the studied HM values do not reach these values after Kloke (1980), which excludes the risk of toxicity, in the studied ecosystems, for plants and soil organisms
