Vasoactive intestinal peptide receptors 1 (VPAC1) and 2 (VPAC2) have been identified in humans. Cell lines expressing only VPAC1 (HT-29) or VPAC2 (Molt-4b) were identified using real-time reverse transcriptase polymerase chain reaction. Vasoactive intestinal peptide (VIP) and related peptides, VIP-6-28, VIP4-28, and VIP10-28, previously isolated from cultures of human leukocytes, were evaluated...

A variety of studies have suggested that the 4b/a polymorphism in the endothelial nitric oxide synthase (eNOS) was associated with coronary artery disease (CAD) risk. However, the data remain conflicting. The aim of the present meta-analysis was to estimate the overall association between risk of CAD and eNOS 4b/a polymorphism. Case-control, cohort or cross-sectional studies evaluating the asso...

The ditelosomic line for the long arm of chromosome 4B (4BL) of Chinese Spring (CS) wheat is not available because it is completely male sterile. Since all deletions in the 4B short arm (4BS) cause male sterility in the homozygous condition, a male-fertility gene should be located in a distal region of 4BS. Among the selfed progeny of a hybrid between a male-sterile 4BS deletion plant (4BS-8) a...

Listeria monocytogenes serotype 4b has been implicated in numerous food-borne epidemics and in a substantial fraction of sporadic listeriosis. A unique lineage of the nonpathogenic species Listeria innocua was found to express teichoic acid-associated surface antigens that were otherwise expressed only by L. monocytogenes of serotype 4b and the rare serotypes 4d and 4e. These L. innocua strains...

The title compound, 6,7-de-hydro-royleanone, C20H26O3 [systematic name: (4bS)-3-hy-droxy-2-isopropyl-4b,8,8-trimethyl-4b,5,6,7,8,8a-hexa-hydro-phenanthrene-1,4-dione] was isolated from Taxodium distichum (L.) Rich. The compound crystallizes in the space group P21. The crystal structure features two O-H⋯O hydrogen bonds, forming chains along the [010] direction.

The title compound [systematic name: (4bS)-4-hy-droxy-2-isopropyl-4b,8,8-trimethyl-4b,5,6,7,8,8a-hexa-hydro-phenanthrene-3,9-dione], C20H26O3, is an abietane-type diterpene, which was isolated from Taxodium ascendens (B.). In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming supra-molecular chains propagating along the [001] direction.

Outbreaks of food-borne listeriosis have often involved strains of serotype 4b. Examination of multiple isolates from three different outbreaks revealed that ca. 11 to 29% of each epidemic population consisted of strains which were negative with the serotype-specific monoclonal antibody c74.22, lacked galactose from the teichoic acid of the cell wall, and were resistant to the serotype 4b-speci...

Serovars of Lisreria l1Iollocyrogelles were determined. Sera of aborted samples (200) were collected from different hospitals in Tehran and were tested serologically by immunofluorescent antibody methods (IF tests). 137 positive sera were identified. Positive sera were tested against 12 serovars of Listeria l1Iollocytogelles separately. Titers of antibody in patients' sera for all serovars ...

Listeria monocytogenes is an opportunistic invasive foodborne pathogen. Here, we performed whole-genome sequencing of L. monocytogenes strain F4244 (serotype 4b) using Illumina sequencing. The sequence showed 94.5% identity with strain F2365, serotype 4b, and 90.6% with EGD-e, serotype 1/2a.

Supplementary Information General Materials. The starting materials were all commercially available, and 1,4-bis(2hydroxyethoxy)-2-butyne (5b) and 2,4-hexadiyne-1,6-diol (8) were prepared according to the literature procedures. The cross-linking agents 3a, 3b, and 4b were reported previously, however, the physical and spectroscopic data of 4b were not described in the literature and were presen...
