In this paper, it was aimed to obtain disposable medical textiles having antibacterial and wound healing properties, as well as biological adaption. For this purpose, the St. John’s Wort oil and flax seed oil were ozonated, and the oils were capsulated with arabic gum. The produced ozonated oils were characterized through FTIR and TGA analyses, as well as the properties of antibacterial, wound healing, and biological adaption were investigated. The produced microcapsules were examined via optical microscope and FTIR. The characterized microcapsules of the ozonated oils were applied to the textiles with padding method. After the applications, the fabrics were researched with SEM and FTIR analyses; in addition the antibacterial and wound healing properties and biological adaption of the textiles were also investigated. The results showed that the St. John’s Wort oil and flax seed oil were successfully ozonated and microcapsulated. The microcapsules of the oils could be applied to the fabric samples with the determined application recipe. The ozonated oils and the fabric samples applied microcapsules of the ozonated oils gained high antibacterial and wound healing property. In addition, the fabric samples were produced as having biological adaptation. 相似文献

Context
Loss and fragmentation of semi-natural grasslands has critically affected many butterfly species in Europe. Habitat area and isolation can have strong effects on the local biodiversity but species may also be strongly affected by the surrounding matrix.Objectives
We explored how different land cover types in the landscape explained the occurrence of butterfly species in semi-natural grasslands.Methods
Using data from 476 semi-natural grasslands in Sweden, we analysed the effect of matrix composition on species richness and occurrence. Additionally, we analysed at which spatial scales butterflies responded to matrix types (forests, semi-natural grasslands, arable land and water).Results
Forest cover showed the strongest positive effect on species richness, followed by semi-natural grasslands. Forest also had a positive effect on red-listed species at local scales. Responses to matrix composition were highly species-specific. The majority of the 30 most common species showed strong positive responses to the amount of forest cover within 200–500 m. There was a smaller group of species showing a positive response to arable land cover within 500–2000 m. Thirteen species showed positive responses to the amount of semi-natural grasslands, generally at larger scales (10–30 km).Conclusions
Our study showed that surrounding forest is beneficial for many grassland butterfly species and that forests might mitigate the negative effects of habitat loss caused by agricultural intensification. Also, semi-natural grasslands were an important factor for species richness at larger spatial scales, indicating that a landscape consisting mainly of supporting habitats (i.e. forests) are insufficient to sustain a rich butterfly fauna.83.

Novel amoxicillin nanoparticles formulated as sustained release delivery system for poultry use 下载免费PDF全文

Amoxicillin is used in the treatment and prevention of a wide range of diseases in poultry breeding. However, its short half‐life and low bioavailability restrict its clinical application in these species. Entrapment of drugs into polymeric nanoparticles (nps) presents a means to improve gastrointestinal absorption and oral bioavailability of drugs. This study was aimed to overcome limitation of amoxicillin use in poultry breeding. Amoxicillin was loaded into sodium alginate‐polyvinyl alcohol (NaAlg‐PVA ) blend nps, and characterization of the prepared nps was performed. For pharmacokinetic study, commercial male broilers were used and comparative pharmacokinetics of free and nanoparticle form of amoxicillin were investigated. Twenty‐one broilers were divided into three groups. All groups received 10 mg/kg drug. Blood samples were collected, and drug plasma concentrations were determined by HPLC . The results demonstrated that the particle size, zeta potential, encapsulation efficiency, and loading capacity of the nps were 513.96 ± 19.46 nm, ?45.36 ± 1.35 mV , 43.66 ± 3.30, and 12.06 ± 0.83%, respectively. In vitro drug release exhibited a biphasic pattern with an initial burst release of 18% within 2 hr followed by a sustained release over 22 hr. The pharmacokinetic results showed that amoxicillin nps have higher bioavailability and longer plasma half‐life (p < .01) than free amoxicillin. These results indicate that amoxicillin nano formulation is suitable for oral administration in broilers. 相似文献

• Introduction
The accurate estimation of stem taper and volume are crucial for the efficient management of the forest resources. Compatible segmented polynomial taper and volume equations were developed for Brutian pine (Pinus brutia Ten.), Lebanon cedar (Cedrus libani A. Rich.), Cilicica fir (Abies cilicica Carr.), Scots pine (Pinus sylvestris L.), and Black pine (Pinus nigra Arnold.). 相似文献88.

: The aim of the present study was to investigate whether epidural administration of a xylazine-lidocaine combination accompanied by xylazine sedation would provide satisfactory analgesia for some surgical procedures on 10 calves admitted to the Department of Veterinary Surgery, University of Kafkas with perineal urolithiasis (n:2), rectovaginal fistula (n:1), atresia ani (n:2), omphalophlebitis (n:2), omphaloarteritis (n:1) and umbilical hernia (n:2).Following intramuscular injection of xylazine at a dose of 0.05 mg/kg for sedation, xylazine-lidocaine combination (0.2 mg/kg lidocaine + 0.02 mg/kg xylazine + 5 ml 0.9% NaCl) was administrated into the lumbosacral (L6-S1), sacrococcygeal (S5-Co1) or intercoccygeal (Co1-Co2) space. Heart rate, respiratory rate and rectal temperature were recorded prior to and during analgesia at 5, 10, 15, 30 and 60 minutes. Furthermore, depth and duration of analgesia were evaluated during surgical intervention.The study revealed that the combination of epidural xylazine-lidocaine with xylazine sedation was highly satisfactory for surgery of the lower urinary tract and the perineal region, but it was less so for surgery of the umbilical area. 相似文献

Passalora blight of anise, caused byPassalora malkoffii (Bubák) U. Braun, is an important disease of anise in Turkey. The disease affects all the aboveground parts of plants including
flower clusters. Infected seeds have dark, linear stromata. Detection of the pathogen on seeds was studied by the blotter
method, agar method, washing test and sowing infected seeds in disease-free soils. The pathogen was recovered only by the
washing test and to a limited extent by water agar + seed decoction agar. Sixteen of 24 seed samples from diseased regions
were found to be infected. The pathogen was not detected by any other methods. However, several indigenous fungi,e.g. Alternaria alternata, were isolated, which may have prevented the growth of the pathogen. Seed washings of infected seed samples had typical spores
of the pathogen up to 106 conidia per gram of seed. Transmission of the pathogen was shown by sowing infected seeds in disease-free field soils in
two locations where anise had not been grown previously. Azoxystrobin, chlorothalonil + carbendazim and flutriafol seed treatments
at 0.04 g a.i. kg−1 seed, 1.0 g + 4.5 g a.i. kg−1 seed and 0.015 g a.i. kg−1 seed reduced the disease by 92.5%, 89.6% and 36.2% in 2002 and by 78.9%, 75.8% and 41.2% in 2003, respectively. Three foliar
applications of axosystrobin, chlorothalonil + carbendazim and flutriafol at the rates of 187.5 g a.i. ha−1, 1500 g + 6750 g a.i. ha−1 and 31.3 g a.i ha−1 reduced disease incidence by 92.5%, 86.0% and 96.8% in 2002 and by 97.5%, 90.8% and 97.0% in 2003, respectively.
