Bicomponent Fiber

Abstract Recently, bicomponent fibers have been attracting much attention due to their unique structural characteristics and properties. A common concern was how to characterize a bicomponent fiber. In this review, we generally summarized the classification, structural characteristics, preparation methods of the bicomponent fibers, and focused on the experimental evidence for the identification of bicomponent fibers. Finally, the main challenges and future perspectives of bicomponent fibers and their characterization are provided. We hope that this review will provide readers with a comprehensive understanding of the design and characterization of bicomponent fibers.

Adrenoceptor Agonists

Ample experimental evidence supports the existence of two distinct types of vasoconstrictor α-adrenoceptors in vascular smooth muscle at postjunctional sites, showing similarities with α1 and α2-adrenoceptors. Especially in vivo, the characterization of an α2-adrenoceptor mediating an increase in diastolic pressure has been most successful. In this respect the model of the pithed rat has been employed most frequently (for reviews see [1, 2]). At present, the agents cirazoline, (−) phenylephrine, (±)-erythro-methoxamine, (−)-amidephrine, SKF89748, St587 and Sgd 101/75 fulfil the criteria for selective α1-adrenoceptor agonists; their log dose-vasopressor effect curves are virtually unaffected by previous treatment with yohimbine or rauwolscine (selective dose in pithed rats: 1 mg/kg), whereas prazosin (selective dose in pithed rats: 0.1 mg/kg) causes an appreciable parallel rightward displacement. The reverse holds true for the stimulants B-HT 920, B-HT 933, B-HT 958, UK-14304, xylazine, TL-99, M-7 and DP-6,7-ADTN, which all have been classified as preferential agonists of vascular postjunctional α-adrenoceptors.

First Time

First time experimental evidence is presented for the steady state growth of dendrites away from their normal crystallographic growth directions. The evidence is shown for transparent dendrites in the succinonitrile system, which are induced to grow along wetting surfaces. A method for the quantitative characterization of the tips of such dendrites is described and the differences in the secondary arm formation between off-axis and regular dendrites are recorded. The scientific and technological implications of this finding are examined.

Coordination Compounds

Coordination compounds of unusual color and stoichiometry PtCl2(CNR)2 are identified by experimental evidence as ionic tetrakis(isonitrile)platinum(II)tetrachloroplatinates(II). The synthesis of several new complexes [Pt(CNR)4][PtCl4] with varying R and of “mixed” compounds [Pt(CNR)2(CNR')2][PtCl4] is described. The influence of the isonitrile ligands in these complexes is discussed especially concerning the resulting solid state properties.

Isolation and characterization of the chicken erythroid anion transporter (band 3) cDNA clone, pCHB3-1, revealed that the chicken erythroid band 3 polypeptide is 844 amino acids in length with a predicted mass of 109,000 daltons. This polypeptide is composed of a hydrophilic N-terminal cytoplasmic domain and a hydrophobic C-terminal transmembrane domain. The approximately 90 N-terminal amino acids of the human and murine erythroid band 3 polypeptides are absent in the predicted sequence of the chicken erythroid band 3 polypeptide. The absence of this very acidic N-terminal region is consistent with the lack of binding of glyceraldehyde-3-phosphate dehydrogenase to chicken erythroid band 3, as well as the relatively basic isoelectric point observed for this molecule. The remainder of the cytoplasmic domain shows little similarity to the cytoplasmic domain of the murine and human erythroid band 3, with the exception of the putative ankyrin-binding site, which is highly conserved. In contrast, the transmembrane domain of the chicken band 3 polypeptide is very similar to that of the murine erythroid and human nonerythroid band 3 polypeptides. The transmembrane domain contains 10 hydrophobic regions that could potentially traverse the membrane 12 to 14 times. In addition, a variant of chicken erythroid band 3, pCHB3-2, was cloned in which one of the hydrophobic regions of pCHB3-1 is lacking. The transcript complementary to pCHB3-2 accumulated in chicken erythroid cells in a similar manner as the transcript complementary to pCHB3-1 during embryonic development. This is the first example of a transporter protein or ion channel with alternative primary structures in its membrane-spanning segments.
