    Abstract. We study the inclusive production of charged and neutral pions in the reactions $p \uparrow p \rightarrow \pi X$ and $\bar{p} \uparrow p \rightarrow \pi X$ in the framework of single spin asymmetries. We propose a two components model where production of pions occurs both by recombination of the constituents present in the initial state and by fragmentation of quarks in the final state. Taking the Thomas precession mechanism in the recombination component into account, we obtain a good description of the experimentally observed single spin asymmetries. We show that the observed single spin asymmetries are consistent with the measured spin alignment in the polarized proton as measured by HERMES and SMC.

    Notes:
    Mixed soy/cow's milk curds were prepared by simultaneous curdling of soy/cow's milk blends, utilizing rennet as cow's milk coagulant and calcium or magnesium sulfate as soymilk coagulant. The method produced curds of similar characteristics (compactness and yield), whether soymilk prepared from soybeans or full-fat soy flour was used. The effect of a number of process variables on curd characteristics was studied, utilizing a fractional factorial design. Generally, large changes in process variables (23 – 230%) produced relatively small charges in curd characteristics (1 – 16%). Protein contents of raw materials and proximate chemical analyses of pure and mixed milk curds, prepared under conditions yielding maximum curd compactness were determined. Protein recoveries in curd preparation were calculated.

    Summary Human herpesvirus 7 (HHV-7) is a close relative of human herpesvirus 6A (HHV-6A) and human herpesvirus 6B (HHV-6B) based on limited biologic and genetic data. In this work we describe physical and genetic maps for HHV-7 strain SB [HHV-7(SB)], which was obtained from the saliva of a healthy adult. The HHV-7(SB) genome length is approximately 144 kb by clamped homogeneous electric field gel electrophoresis and approximately 135 kb by summation of restriction endonuclease fragments. We constructed plasmid clones and PCR amplimers that span the HHV-7 genome, except for the genomic termini, and determined the maps of the restriction endonuclease cleavage sites forBamHI,PstI, andSacI. The HHV-7(SB) genome is composed of a single unique region of approximately 122 kb bounded at each end by a 6 kb direct repeat. Homologs to thirty-five herpesvirus genes were identified. The highest similarity was with the HHV-6 genes, with an average amino acid identity of 50%, followed by the human cytomegalovirus counterpart. The genomic and genetic maps indicated that the HHV-7 and HHV-6 genomes are colinear. There was no sequence variation in a segment of the gene encoding the DNA polymerase-associated factor homolog among six HHV-7 isolates, while the corresponding segment of the HHV-6A and HHV-6B counterparts differed by 4.6%. These data support previous observations that the closest genetic relatives of HHV-7 are betaherpesviruses.

    Abstract Background:Small-cell lung cancer (SCLC), one of the major types of lung cancer, is associated with many different somatic molecular genetic changes. These alterations, observed in tumor DNA, have also been identified in the plasma DNA of patients. We undertook the present study to make a prospective investigation into the correlation between abnormal plasma DNA and patient survival. Patients and methods:Thirty-five patients with SCLC were selected after histological diagnosis. Polymorphic markers (ACTBP2, UT762 and AR) were chosen for their reported high rate of alterations in SCLC and analyzed in tumor tissue, normal blood cells and plasma DNA. Furthermore, we looked for mutations of the TP53 gene in tumor and plasma DNA. Results:In 25 patients (71%) at least one molecular change precisely matching that of the primary tumor was detected in the plasma DNA. No difference in survival was observed between patients with aberrant plasma DNA and patients without plasma DNA alterations. However, patients with microsatellite modifications and TP53 mutations concomitantly, showed a significant difference (P = 0.02) in survival compared with patients bearing only one of these molecular changes. In 15 cases it was possible to find a correlation either between tumor response and disappearance of abnormal plasma DNA, or tumor progression and persistence of plasma DNA alterations. Conclusions:Free plasma DNA with molecular alterations is present to a high degree in plasma DNA of SCLC patients and may have a role as a prognostic factor.

    Notes:
    The assignment of the proton and carbon spectra of some cyclopropane sesquiterpene lactone derivatives of helenalin and anhydroparthenin is presented. The interpretation of the spectra was achieved using 1H-13C two-dimensional heteronuclear chemical shift correlation, proton two-dimensional homonuclear correlated 2D and 2D-J, and some classical techniques. In particular, the spectra of halocyclopropane derivatives are discussed and compared with the spectra of the parent sesquiterpenes.
