The dynamic foam column is a new culture where the whole plant body is wrapped continually by dynamic foam. The efficiency of dynamic foam was confirmed through a sequence of short-term experiments : basil seeds germinated and grew into cotyledon and foliage leaf stage ; scion of basil, komastuna and impatiens rooted ; basil and komastuna that had grown beforehand in hydro culture, grew well in dynamic foam. Chrysanthemum green and pellia, however, turned transparent like a submerged leaf. In short, wet dynamic foam of this study was a good culture medium for some plants but not for others.Dynamic foam is an excellent culture : it delivers water, nutriments, gases and pesticides both to the aerial and the subterranean part of the plant ; dynamic foam is one of the highest insulators against thermal and biological invasion

Mild fetal cerebral ventriculomegaly as a prenatal sonographic marker for Kartagener syndrome
Primary ciliary dyskinesia (PCD), also referred to as immotile-cilia syndrome or Kartagener syndrome, is a group of genetic disorders caused by defective cilia leading to chronic sinupulmonary infection, situs inversus and reduced fertility. Some PCD patients also have cerebral ventriculomegaly or hydrocephalus. We report here two fetuses and one newborn with mild cerebral ventriculomegaly and a suspected and/or confirmed diagnosis of PCD. These cases demonstrate that mild fetal cerebral ventriculomegaly can be a prenatal sonographic marker of PCD, certainly in fetuses with situs inversus or a history of a previous sib with PCD.

Kompleksi fibronektinskih fragmenata i imunoglobulina G u gingivalnoj tečnosti osoba obolelih od parodontopatije
Introduction Fibronectin (FN) can interact with immunoglobulin G (IgG) molecules affecting the process of physiological elimination and causing abnormal deposition of immune complexes. The aim of the study was to analyze interaction between FN fragments and IgG molecules with different glycosylation profiles in gingival crevicular fluid (GCF) of patients with periodontal disease and healthy controls. Material and Methods The study included 30 patients with moderate and advanced periodontitis and 22 healthy subjects. IgG and FN content in GCF were measured as well as the presence of FN and galactose expression on IgG molecules. Results IgG content in GCF was five times higher in patients with moderate (p lt 0.01) and eight time higher in patients with advanced periodontitis (p lt 0.001) compared to healthy subjects. Also, hypogalactosylated forms of IgG were found in higher concentration in GCF of patients with advanced periodontitis compared to moderate periodontitis and healthy subjects (p lt 0.05). FN fragments of molecular mass 48 - 53 kDa were the most commonly found fragments in all three groups. Furthermore, in patients with advanced periodontitis, fibronectin fragments were attached to IgG molecules. Conclusion IgG and FN fragments form complexes in GCF in patients with periodontal disease and healthy subjects.Uvod Fibronektin može da interreaguje s molekulima imunoglobulina G (IgG) i utiče na normalan klirens ili poremećeno deponovanje imunskih kompleksa. Cilj ovog rada je bio da se ispita veza između fibronektina i IgG različitih glikoformi u gingivalnoj tečnosti osoba obolelih od parodontopatije i parodontalno zdravih ispitanika. Materijal i metode rada U studiju je uključeno 30 pacijenata s umerenom i uznapredovalom parodontopatijom i 22 parodontalno zdrave osobe. U gingivalnoj tečnosti određivan je sadržaj IgG i fibronektina dot blot i imunoblot tehnikama. IgG iz gingivalnih tečnosti su afinitetno izolovani i analizirani na prisustvo fibronektina i ekspresiju galaktoze. Rezultati Sadržaj IgG u gingivalnoj tečnosti osoba s umerenom parodontopatijom bio je oko pet puta veći u odnosu na sadržaj IgG kod zdravih osoba (p lt 0,01), dok je kod uznapredovalih oblika bio oko osam puta veći (p lt 0,001). Takođe, hipogalaktozilovane forme IgG su većoj meri postojale kod osoba sa uznapredovalom parodontopatijom u odnosu na zdrave i osobe s umerenom parodontopatijom (p lt 0,05). U sve tri analizirane grupe dominirali su fibronektinski fragmenti od 48 do 53 kDa. Uočeno je da su IgG izolovani iz gingivalne tečnosti vezani za fragmente fibronektina, pri čemu su IgG osoba sa uznapredovalom parodontopatijom, imali najveću količinu ovih vezanih fragmenata. Zaključak Dobijeni rezultati pokazuju da IgG gingivalne tečnosti zdravih i osoba s parodontopatijom formiraju komplekse sa fibronektinom
Influence of crop load on the expression patterns of starch metabolism genes in alternate-bearing Citrus trees
[EN] The fruit is the main sink organ in Citrus and captures almost all available photoassimilates during its development. Consequently, carbohydrate partitioning and starch content depend on the crop load of Citrus trees. Nevertheless, little is known about the mechanisms controlling the starch metabolism at the tree level in relation to presence of fruit. The aim of this study was to find the relation between the seasonal variation of expression and activity of the genes involved in carbon metabolism and the partition and allocation of carbohydrates in 'Salustiana' sweet orange trees with different crop loads. Metabolisable carbohydrates, and the expression and activity of the enzymes involved in sucrose and starch metabolism, including sucrose transport, were determined during the year in the roots and leaves of 40-year-old trees bearing heavy crop loads ('on' trees) and trees with almost no fruits ('off' trees).
Fruit altered photoassimilate partitioning in trees. Sucrose content tended to be constant in roots and leaves, and surplus fixed carbon is channeled to starch production. Differences between 'on' and 'off' trees in starch content can be explained by differences in ADP-glucose pyrophosphorylase (AGPP) expression/activity and alpha-amylase activity which varies depending on crop load. The observed relation of AGPP and UGPP (UDP-glucose pyrophosphorylase) is noteworthy and indicates a direct link between sucrose and starch synthesis. Furthermore, different roles for sucrose transporter SUT1 and SUT2 have been proposed. Variation in soluble sugars content cannot explain the differences in gene expression between the 'on' and 'off' trees. A still unknown signal from fruit should be responsible for this control.The authors thank Dr. E. Primo-Millo for critically reviewing the manuscript.
