lamb. Keywords: arthrogryposis, craniorachischisis, diprosopus, lamb Congenital malformations are structural and functional abnormalities present at birth. They can affect a single structure or function, parts of various systems, or an entire system [14]. The incidence of these abnormalities is reported to vary between 0.2% and 2% in lambs [3]. Congenital malformations with multiple anomalies... Congenital malformations with multiple anomalies have been described infrequently in the veterinary literature. A stillborn male crossbred lamb with diprosopus, craniorachischisis, and arthrogryposis was examined macroscopically and histopathologically in this study. The left head was smaller than the right head. Micrencephaly, agnathia, and a rudimentary tongue, which was adherent to the palate, were present in the left head. Micrencephaly, brachygnathia superior, and cleft palate were present... -

(Fig. 1B) while the cross sections showed intra and intercelullarly colonized hyphae in the epidermis as well as in the mesophyll (Fig. 2A and E). The colonized hyphae were intermingled; they deformed the host cells and tissues so that they were hardly differentiated (Figs. 2C and D). Structural defense development. The thickness of the cell wall in mesophyll cells in the infected lesion was... observe the structural modification against pathogen. The cuticle and epidermal cells along with 3–5 layers of mesophyll tissue were degraded 1–2 days post inoculation. Surrounding peripheral cells of degraded tissues grew rapidly and then enveloped the necrotic area along with the growing conidia. Cross sections through the lesion revealed hyphal colonization in epidermis and mesophyll tissues. In response to the pathogen colonization, host cell walls were lignified, inner... -

D., Ping, G., Daly, S. L., Cha, C., Cronan, J. E. Jr., Rine- hart, K. L. and Farrand, S. K. 1997. Detecting and characteriz- ing N-acylhomoserine lactone signal molecules by thin-layer chromatography. Proc. Natl.... Numerous root-associated bacteria (rhizobacteria) are known to elicit induced systemic resistance (ISR) in plants. Bacterial cell-density-dependent quorum sensing (QS) is thought to be important for ISR. Here, we investigated the role of QS in the ISR elicited by the rhizobacterium, Serratia marcescens strain 90?166, in tobacco. Since S. marcescens 90?166 produces at least three QS signals, QS-mediated ISR in strain 90?166 has been difficult to understand. Therefore, we investigated the ISR... -

at 30 oC (Fig. 5). Moreover, the archi- tecture and angle of hyphal branching were also severely altered. The reaction of BA and PA to the fungal cell wall caused the hyphae to be severely distorted, deformed and somewhat enlarged at the tip while the normal shape and branching was maintained in control (Fig. 5C). Biocontrol of P. capsici by B. cepacia MPC-7 on pepper in vivo. The root mortality ... A chitinolytic bacterial strain having strong antifungal activity was isolated and identified as Burkholderia cepacia MPC-7 based on 16S rRNA gene analysis. MPC- 7 solubilized insoluble phosphorous in hydroxyapatite agar media. It produced gluconic acid and 2-ketogluconic acid related to the decrease in pH of broth culture. The antagonist produced benzoic acid (BA) and phenylacetic acid (PA). The authentic compounds, BA and PA, showed a broad spectrum of antimicrobial activity against yeast,... -

in host cells were rounded, with cristae swollen and deformed, and gradually disintegrated from the centre leading to collapse. The double membrane became a single or partially ruptured and vesiculated. The endoplasmic reticulum within host cells was irregular in shape, and gradually vesiculated. The polymerized ribosomes in the cytoplasm were depolymerized into single units. The other host... The induced resistance of cucumber leaves treated with oligochitosan to the infection of the cucumber powdery mildew, Sphaerotheca fuliginea, was investigated using transmission electron microscopy. The results showed that when the plants were treated with oligochitosan and challenged with inoculum, a significant decrease of the disease occurred. The mycelial development in the treated leaves was markedly inhibited. The cytoplasm of the powdery mildew mycelium was aggregated, with its organelles... -

2Dxykxky which is related to the bending stiffness components, Dxx, Dyy, and Dxy that relate the applied moments to the deformed curvatures. If it is assumed that the curvatures κx and κy are the same for the square plates (Lx=Ly), and that κxy is zero for the deformed shape of a composite plate during the impact event, then the strain energy is thought to be partially proportional to D *... Impact damages induced by a low-velocity impact load on carbon fiber reinforced polymer (CFRP) composite plates fabricated with various stacking sequences were studied experimentally. The impact responses of the CFRP composite plates were significantly affected by the laminate stacking sequences. Three types of specimens, specifically quasi-isotropic, unidirectional, and cross-ply, were tested by a constant impact carrying the same impact energy level. An impact load of 3.44 kg, corresponding to... -

Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -

the fact that the CVD-grown graphene contains more structural disorders, ranging from atomic-scale defects to nanometer-scale ripples and folds created during growth and transfer [26], respectively. The chemical reactivity of graphene is considered to increase with the increase of the degree of its structural disorder [12]. The photoreactions of graphene demonstrated in the current study can... -

to study the structural features of the cotton stalk raw material and activated sample (CCS-1K800). Before scanning, the selected samples were coated with gold (Au) using a quick auto- coater (JFC-1500, JEOL). The surface functional groups were qualitatively determined by FTIR spectra of cotton stalks raw as well as for two selected carbons CCS-1K800 and CCS-4K800, recorded within the wavenumber...
