TOTAL POLYPHENOLS, FLAVONOIDS CONTENTS AND ANTIOXIDANT ACTIVITY OF ROSA SP. GENOTIPES FROM DIFFERENT ALTITUDE OF ROMANIAN REGIONS
Eight wild rose hip genotypes from different altitudes varying from 3m to 902m were analyzed in order to evaluate the total polyphenols, flavonoids content and the antioxidant activity. The Rosa spp.rosehips collected from the Northeastern and the Southeasternof Romanianwere, as follows: Rosa canina, R. caesia, R. corymbifera, R. micrantha, R. nitidula, R. rubiginosa, R. subcanina, and R. vosagiaca. In some genotypes, the level of flavonoids and polyphenol content increased with the increasing altitude while in other it was observed a decrease. Polyphenol content reached a maximum of 144.36 mg GAE/g DW in R. rubiginosa whereas the lowest content of 61.72 mg GAE/g DW was recorded in R. caesia. The highest polyphenol content was reached at altitude of 860 m. The amount of flavonoids content ranged between 7.32 mg CE/g DW and 19.45 CE/g DW in R. caesia and in R. nitidula, respectively. The radical scavenging capacities of Rosa genotypes extracts were not positively correlated with altitude, except the R. corymbifera extractswhere the antioxidant activity increased with the increase of altitude
Modernity and the Water Calligraphy Experience
This article explores how Chinese calligraphy has evolved in the modern world, utilizing one particular focus: water calligraphy. Water calligraphy is a fascinating, non-invasive, and communal form of street art. It recontextualizes traditional calligraphy and offers insight into modern Chinese society and the concepts of art and creation. The simple trade of ink and paper for water and the ground has produced one highly intriguing practice. The following article will go through water calligraphy\u27s link to modernity, its general appeal, and my own personal experience attempting it
ENZYMATIC ACTIVITY AND SOLUBLE PROTEIN CONTENT IN SEEDLINGS OF CALENDULA OFFICINALIS L. UNDER SALT STRESS
[EN] Enzymatic activity and soluble protein content in relation to salt stress tolerance were investigated in
Calendula officinalis seedlings after 24 days of treatment with different salt treatments, including
NaCl, CaCl2, MgCl2 and mixtures of them. The marigold seedlings were used in order to investigate
the possible salt-inducible responses and the possible alleviative role of calcium and magnesium salts
in respect with adverse salinity conditions. Activity of superoxide dismutase (SOD; EC 1.15.1.1) and
peroxidase (POD; EC 1.11.1.7) generally slightly decreased under salt treatments, with minor
variations from the value recorded for control series and within applied treatments. Catalase (CAT; EC
1.11.1.6) activity was stimulated by NaCl salinity and MgCl2 addition; its activity was found to be
lowest under calcium and magnesium chloride treatments solelyOprica, L.; Vicente Meana, Ó.; Boscaiu Neagu, MT.; Grigore, MN. (2016).

GEOMETRIC STUDY IN THE REALIZATION OF CONCRETE FURNITURE
When we are looking to make a piece of furniture, indoor or outdoor, we immediately think that the requirements related to functionality, ergonomics, flexibility, aesthetics and design will be met. At the same time, through these pieces of furniture, we give the space personality. But in order to obtain the desired shape, we go through a series of studies based on geometrical study. With the unlimited possibilities offered by technology, we have the opportunity to obtain increasingly complex forms of furniture, with a high degree of industrialization, from various materials. Concrete is a beautiful, affordable, weather-resistant material, versatile and suitable for any space, interior or exterior. The purpose of this work is to present such a creative process and the stages that take place in the realization of the concrete furniture piece
Characterizing the effects of salt stress in Calendula officinalis L
[EN] In this study the effects of salt stress on growth and several stress markers were investigated in the ornamental and medicinal plant Calendula officinalis. One-month-old plants were submitted to increasing salt concentrations, up to 150 mM NaCl, for a period of
30 days. Salinity affected growth in terms of relative reduction of stem length and fresh weight of the plants, but water content remained unchanged indicating a certain tolerance to low and mild NaCl concentrations. Although Na+ and Cl- increased in parallel to increasing salinity, the levels of K+ and Ca2+ showed no significant change, while Mg2+ levels recorded a twofold increase upon the ap-
plication of the highest salt concentration. Other measured para-
meters showed a more significant change, notably proline levels, which registered a nine-fold increase in the presence of 150 mM NaCl. In conclusion, although plants suffered from salt stress, as shown by the degradation of photosynthetic pigments and induction of oxidative stress (increased MDA levels), they continued their ve-
getative growth under low concentrations of salt. The main mechanisms of response to salt stress in this species appear to be based on the maintenance of K+ and Ca2+ homeostasis and the accumulation of proline as a functional osmolyte.Kozminska, A.; Al Hassan, M.; Kumar, D.; Oprica, L.; Martinelli, F.; Grigore, MN.; Vicente, O....

Population Genetic Analysis of Propionibacterium acnes Identifies a Subpopulation and Epidemic Clones Associated with Acne
The involvement of Propionibacterium acnes in the pathogenesis of acne is controversial, mainly owing to its dominance as an inhabitant of healthy skin. This study tested the hypothesis that specific evolutionary lineages of the species are associated with acne while others are compatible with health. Phylogenetic reconstruction based on nine housekeeping genes was performed on 210 isolates of P. acnes from well-characterized patients with acne, various opportunistic infections, and from healthy carriers. Although evidence of recombination was observed, the results showed a basically clonal population structure correlated with allelic variation in the virulence genes tly and camp5, with pulsed field gel electrophoresis (PFGE)- and biotype, and with expressed putative virulence factors. An unexpected geographically and temporal widespread dissemination of some clones was demonstrated. The population comprised three major divisions, one of which, including an epidemic clone, was strongly associated with moderate to severe acne while others were associated with health and opportunistic infections. This dichotomy correlated with previously observed differences in in vitro inflammation-inducing properties. Comparison of five genomes representing acne- and health-associated clones revealed multiple both cluster- and strain-specific genes that suggest major differences in ecological preferences and redefines the spectrum of disease-associated virulence factors. The results of the study indicate that particular clones of P. acnes play an etiologic role in acne while others are associated with health
Systematic review and meta-analysis of the efficacy of interleukin-1 receptor antagonist in animal models of stroke: an update
Interleukin-1 receptor antagonist (IL-1 RA) is an anti-inflammatory protein used clinically to treat rheumatoid arthritis and is considered a promising candidate therapy for stroke. Here, we sought to update the existing systematic review and meta-analysis of IL-1 RA in models of ischaemic stroke, published in 2009, to assess efficacy, the range of circumstances in which efficacy has been tested and whether the data appear to be confounded due to reported study quality and publication bias. We included 25 sources of data, 11 of which were additional to the original review. Overall, IL-1 RA reduced infarct volume by 36.2 % (95 % confidence interval 31.6–40.7, n = 76 comparisons from 1283 animals). Assessments for publication bias suggest 30 theoretically missing studies which reduce efficacy to 21.9 % (17.3–26.4). Efficacy was higher where IL-1 RA was administered directly into the ventricles rather than peripherally, and studies not reporting allocation concealment during the induction of ischaemia reported larger treatment effects. The preclinical data supporting IL-1 RA as a candidate therapy for ischaemic stroke have improved. The reporting of measures to reduce the risk of bias has improved substantially in this update, and studies now include the use of animals with relevant co-morbidities.
