the present investigation was conducted to study the effects of experimental clostridium perfringens type d enterotoxaemia in teddy goats. clinical signs started to appear after 30 min of experimental infection like anorexia, diarrhea, dehydration, frothing and dyspnea. gross lesions consisted of severe congestion in tissues of varying intensity with enlarged mesenteric lymph nodes while histol...

OBJECTIVES The aim of this study was to compare apical sealing ability of alpha and beta phases of gutta-percha by means of bacterial leakage model. MATERIALS AND METHODS Fifty single-rooted human premolars were selected. The root canals were prepared with Mtwo rotary instruments up to apical #35.04. Forty teeth were randomly divided into two groups (n= 20). The root canals were obturated by ...

The regulation of nicotinic acetylcholine receptors (AChRs) in chick ciliary ganglia was examined by using a radiolabeled anti-AChR mAb to quantitate the amount of receptor in ganglion detergent extracts after preganglionic denervation or postganglionic axotomy. Surgical transection of the preganglionic input to the ciliary ganglion in newly hatched chicks caused a threefold reduction in the to...

Like molecules of life (e.g., proteins and DNA), many pharmaceutical drugs are also asymmetric (chiral); they are not superimposable on their mirror images. One mirror image form (enantiomer) of a drug can have desirable activity, the other not. Consequently, the development of methods for the selective synthesis of one enantiomer is of great scientific and economic importance. We report here t...

there are significant structural differences between the mouth and pharyngeal cavity of birds and mammals. it is usual to refer to a common oropharyngeal cavity of birds because the soft palate, which forms such an obvious delineation between the mouth and pharyngeal cavity, is absent. six male adult ostriches were used to study the oropharyngeal cavity and its components including the beak, ha...

The molecular basis of the deficiency of alpha-L-fucosidase has been investigated in eight patients who had been diagnosed clinically and enzymatically as suffering from the autosomal recessive lysosomal storage disease fucosidosis. None of the patients had a deletion or gross alteration of the alpha-L-fucosidase gene (FUCA1). Single strand conformation polymorphism (SSCP) analysis followed by ...

A Gross space is a vector space E of infinite dimension over some field F , which is endowed with a symmetric bilinear form Φ : E → F and has the property that every infinite dimensional subspace U ⊆ E satisfies dimU < dimE. Gross spaces over uncountable fields exist (in certain dimensions) (see [G/O]). The existence of a Gross space over countable or finite fields (in a fixed dimension not abo...

Working papers from the Stockholm Institute of Transition Economics and East European Economies are preliminary in nature, and are circulated to promote discussion and critical comment. Any references to individual working papers should clearly state that the paper is preliminary. The views expressed here are the authors' own and not necessarily those of the Institute or any other organization ...

Examples 1.1. • Y ∼= P, D a nodal cubic. • Y a complete nonsingular toric surface, D the toric boundary (i.e, the complement of the big torus orbit Gm). • Blowups: Given a Looijenga pair (Y ,D), we can take “toric blowups,” where Y is the blowup of Y at a nodal point of D and D is the inverse image of D). Note that toric blowups do not change U . “non-toric blowups,” where Ỹ is the blowup of Y ...
