A noticeable eruption was observed with round erythematous-edematous lesions measuring approximately 1 to 2 cm in diameter, with clear vesicular blisters that were predominant at the periphery of the lesions (Figure 1). The eruption was well extended on the back and in isolated areas of the upper limbs and thorax, with sparing of the acral areas. The patient also presented conjunctivitis in the...

A case is reported of a patient who had previously undergone autologous bone marrow transplantation for recurrent Hodgkin's disease. The patient developed a generalised vesicular skin eruption. The clinical diagnosis was of disseminated shingles. Herpes viral particles were identified within the vesicular fluid by electron microscopy and using a specific monoclonal antibody to varicella zoster ...

Electron-dense, granular (rarely vesicular) bodies, some 30 m/x or more in diameter, are seen lying in the ground cytoplasm in the vicinity of the smooth-surfaced membranous complex. They often appear to be embedded in amass of amorphous material, which is of about the same electron-density as the granules themselves. Granules and vesicles, similar in appearance to those mentioned above, have a...

Dissection and histological analyses revealed the swimbladder of Hemiramphus far and H. robustus to comprise a matrix of discrete, gas-filled vesicles of 1–6 mm in diameter. The vesicles are not richly vascular and no discrete capillary bed organs were found. The anterior and posterior ends of the swimbladder have asymmetric projections that extend rostrad and caudad, respectively. These projec...

A simple and effective means for obtaining hollow silica particles of controlled diameter from about 60 to 120 nm is presented. The synthesis utilizes equilibrium vesicles as templates for the directed growth of silica. Two different surfactant systems are used to form the vesicular templates: (a) mixtures of cetyltrimethylammonium bromide (CTAB) and sodium perfluorooctanoate (FC7) and (b) mixt...

Asthma is the most common respiratory disease, affecting an estimated 262 million people and resulting in 461,000 fatalities 2019. The treatment available on market, but it quite expensive, also has serious adverse effects due to high concentration of steroids medicine. If given effectively, curcumin, formononetin, matrine’s anti-inflammatory properties can play a significant role treatment. To...

Pollen tubes are highly polarized plant cells specialized in delivering sperm for fertilization. Pollen tube growth is rapid, occurs exclusively at the tip, and can reach distances thousands of times the diameter of the pollen grain without cell division, thus representing an excellent model system for studying asymmetric cell growth. In flowering plants, pollen tube growth is dependent on the ...

Populations enriched in prophase cells were obtained either by using a cell line with a temperature-sensitive mutation in the mitotic kinase, p34cdc2, or by treating cells with olomoucine, an inhibitor of this kinase. Both methods resulted in efficient and reversible block of the cells at the G2/M boundary. After cells were released from the cell cycle block, the morphological changes to the Go...

Detailed work on Quaternary volcanism has been carried out in the Mermoz and Fann sectors of western Senegal. In sector, main emission zone is a collapsed crater located at intersection three major fractures: NE-SW, NW-SE N-S. The lithological succession this sector comprises, from bottom to top: 1) substratum with its base Eocene limestones which lie sands surmounted by stratified tuffs; 2) ve...
