Lactobacillus plantarum Dad-13 is a potential probiotic candidate, and microencapsulation is the method for extending its shelf-life. Furthermore, spray or freeze -drying is a common method for microencapsulation, and its effect on the stability of probiotic is strain-dependent. This research was aimed to evaluate the strain-dependent effect of probiotic microencapsulation and to choose a suitable method for further research. In this research, for strain-dependent analysis, L. plantarum strain Mut-7 was used as a comparison. Probiotics were encapsulated with 10% (w/v) skim milk and 1 % (w/v) sucrose as wall material by spray and freeze-drying method. The obtained probiotics powder was then analyzed for physicochemical, sublethal injury and stability during storage. Freeze-dried L. plantarum Dad-13 was than analyze the antibacterial activity against pathogenic bacteria. The results showed that aw, color and particle diameter were significantly different between the spray and freeze-dried probiotics. Hence, the microstructure of spray-dried microcapsule was spherical and wrinkle, while the freezedried microcapsule was porous. However, the viable cell of freeze-dried probiotic was significantly higher and more stable during eight weeks of storages. From both strains, we found that there was no strain-dependent effect on viable cells after the drying method. Thus, we deduced that freeze-drying was the suitable method for microencapsulation L. plantarum strain Dad-13, considering the freeze-dried L. plantarum Dad-13 still had antibacterial activity.

The aim of this study was to investigate the influence using combination of maltodextrin and whey (1:3, 2:2 and 3:1)  as wall material due to quality characteristic of cinnamon (Cinnamon burmanii) oleoresin microencapsulan, including yield, water content, solubility in water, microstructure appeareance, cinnamaldehyde content, and residue of solvent. First of all, the oleoresin was reached from extraction using ethanol 96 % for 4 hours. Then the oleoresin emultion was dried using spray drying method. The experimental design used in this research was Completely Randomized Design (CRD) with one factor (rasio of wall material). The result showed that combination of wall material had significant effect to yield (14,98 - 22,69%), water content (6,20 - 7,04%), residue of solvent (00,50 - 0,63%), cinnamaldehyde content (26,18 - 43,90%), and microstructure appeareance, but unsignificantly affected to solubility in water (92,85 - 95,24%).

Extended AbstractWe have examined the morphological properties of a sigmoid associated with an SXR (soft X-ray) flare. The sigmoid is cospatial with the EUV (extreme ultra violet) images and in the optical part lies along an S-shaped Hαfilament. The photoheliogram shows flux emergence within an existingδtype sunspot which has caused the rotation of the umbrae giving rise to the sigmoidal brightening.It is now widely accepted that flares derive their energy from the magnetic fields of the active regions and coronal levels are considered to be the flare sites. But still a satisfactory understanding of the flare processes has not been achieved because of the difficulties encountered to predict and estimate the probability of flare eruptions. The convection flows and vortices below the photosphere transport and concentrate magnetic field, which subsequently appear as active regions in the photosphere (Rust & Kumar 1994 and the references therein). Successive emergence of magnetic flux, twist the field, creating flare productive magnetic shear and has been studied by many authors (Sundara Ramanet al.1998 and the references therein). Hence, it is considered that the flare is powered by the energy stored in the twisted magnetic flux tubes (Kurokawa 1996 and the references therein). Rust & Kumar (1996) named the S-shaped bright coronal loops that appear in soft X-rays as ‘Sigmoids’ and concluded that this S-shaped distortion is due to the twist developed in the magnetic field lines. These transient sigmoidal features tell a great deal about unstable coronal magnetic fields, as these regions are more likely to be eruptive (Canfieldet al.1999). As the magnetic fields of the active regions are deep rooted in the Sun, the twist developed in the subphotospheric flux tube penetrates the photosphere and extends in to the corona. Thus, it is essentially favourable for the subphotospheric twist to unwind the twist and transmit it through the photosphere to the corona. Therefore, it becomes essential to make complete observational descriptions of a flare from the magnetic field changes that are taking place in different atmospheric levels of the Sun, to pin down the energy storage and conversion process that trigger the flare phenomena.

Urinary Glycoprotein

Much work has been reported on the chemical, physical and morphological properties of urinary Tamm-Horsfall glycoprotein (THG). Although it was once reported that cystic fibrotic (CF) individuals had a defective THG, more recent data indicate that THG and CF-THG are similar if not identical.No studies on the conformational aspects have been reported on this glycoprotein using circular dichroism (CD). We examined the secondary structure of THG and derivatives under various conditions and have correlated these results with quaternary structure using electron microscopy.THG was prepared from normal adult males and CF-THG from a 16-year old CF female by the method of Tamm and Horsfall.

Electron microscopy has proved to be an invaluable discipline in studies on the relationship of viruses to the origin of leukemia, sarcoma, and other types of tumors in animals and man. The successful cell-free transmission of leukemia and sarcoma in mice, rats, hamsters, and cats, interpreted as due to a virus or viruses, was proved to be due to a virus on the basis of electron microscope studies. These studies demonstrated that all the types of neoplasia in animals of the species examined are produced by a virus of certain characteristic morphological properties similar, if not identical, in the mode of development in all types of neoplasia in animals, as shown in Fig. 1.

Bulbous Tip

Plant stinging emergences exhibit functional similarities in that they all elicit a pain response upon contact. A stinging emergence consists of an elongated stinging cell and a multicellular pedestal (Fig. 1). A recent ultrastructural investigation of these structures has revealed the ontogeny and morphology of the stinging cells differs in representative genera in the four plant families which possess such structures. A unique feature of the stinging cell of Urtica dioica is the presence of a siliceous cell wall in the apical portion of the cell. This rigid region of the cell wall is responsible for producing the needle-like apparatus which penetrates the skin. The stinging cell differentiates the apical bulbous tip early in development and the cell continues growth by intercalary addition of non-silicified wall material until maturity.The uppermost region of the stinging cell wall is entirely composed of silica (Fig. 2, 3) and upon etching with a 3% solution of HF (5 seconds), the silica is partially removed revealing the wall consisting of individualized silica bodies (Fig. 4, 5).

Phonological Rule

Alternations between allomorphs that are not directly related by phonological rule, but whose selection is governed by phonological properties of the environment, have attracted the sporadic attention of phonologists and morphologists. Such phenomena are commonly limited to rather small corners of a language's structure, however, and as a result have not been a major theoretical focus. This paper examines a set of alternations in Surmiran, a Swiss Rumantsch language, that have this character and that pervade the entire system of the language. It is shown that the alternations in question, best attested in the verbal system, are not conditioned by any coherent set of morphological properties (either straightforwardly or in the extended sense of ‘morphomes’ explored in other Romance languages by Maiden). These alternations are, however, straightforwardly aligned with the location of stress in words, and an analysis is proposed within the general framework of Optimality Theory to express this. The resulting system of phonologically conditioned allomorphy turns out to include the great majority of patterning which one might be tempted to treat as productive phonology, but which has been rendered opaque (and subsequently morphologized) as a result of the working of historical change.
