A Gram-staining-negative, aerobic, non-motile, non-gliding, yellow-pigmented and rod-shaped bacterial strain, designated S7-2T, was isolated from a tidal flat sediment at Saemankum on the west coast of Korea and investigated using a polyphasic taxonomic approach. Strain S7-2T grew optimally at pH 7.0–8.0, at 25–30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain S7-2T clustered with Lutibacter litoralis CF-TF09T, a member of the family Flavobacteriaceae, with which it showed 95.8 % 16S rRNA gene sequence similarity. It contained MK-6 as the predominant menaquinone and iso-C15 : 0 and C15 : 1 ω6c as the major fatty acids. The major polar lipids of strain S7-2T and L. litoralis JCM 13034T were phosphatidylethanolamine and three unidentified lipids. The DNA G+C content was 34.6 mol%. Differential phenotypic properties and phylogenetic distinctiveness suggested that strain S7-2T represents a novel species of the genus Lutibacter, for which the name Lutibacter maritimus sp. nov. is proposed. The type strain is S7-2T (=KCTC 22635T=CCUG 57524T).

We have resolved B220+ IgM- B-lineage cells in mouse bone marrow into four fractions based on differential cell surface expression of determinants recognized by S7 (leukosialin, CD43), BP-1, and 30F1 (heat stable antigen). Functional differences among these fractions can be correlated with Ig gene rearrangement status. The largest fraction, lacking S7, consists of pre-B cells whereas the others, expressing S7, include B lineage cells before pre-B. These S7+ fractions, provisionally termed Fr. A, Fr. B, and Fr. C, can differentiate in a stromal layer culture system. Phenotypic alteration during such culture suggests an ordering of these stages from Fr. A to Fr. B to Fr. C and thence to S7- pre-B cells. Using polymerase chain reaction amplification with pairs of oligonucleotide primers for regions 5' of JH1, DFL16.1, and Jk1, we find that the Ig genes of Fr. A are in germline configuration, whereas Fr. B and C are pro-B cell stages with increasing D-J rearrangement, but no V-D-J. Finally, functional analysis demonstrates that the proliferative response to IL-7, an early B lineage growth factor, is restricted to S7+ stages and, furthermore, that an additional, cell contact-mediated signal is essential for survival of Fr. A.

A psychrotolerant, Gram-negative, rod-shaped, yellow-pigmented bacterium, designated strain R-S7-29T, was isolated from a soil sample collected from the Svalbard Archipelago in Norway (78° N). Cells were non-motile, aerobic, and catalase- and oxidase-positive. Growth occurred at 4–28 °C (optimum, 18 °C). A phylogenetic tree based on 16S rRNA gene sequences showed that strain R-S7-29T belongs to the genus Dyadobacter (family ‘ Flexibacteraceae ’) with sequence similarity to related members of the genus ranging from 95.2 to 96.7 %. The major fatty acids were C16 : 1ω5c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and the predominant respiratory quinone was MK-7. The DNA G+C content of strain R-S7-29T was 50 mol%. On the basis of its phenotypic, phylogenetic and chemotaxonomic properties, strain R-S7-29T represents a novel species of the genus Dyadobacter , for which the name Dyadobacter arcticus sp. nov. is proposed. The type strain is R-S7-29T ( = CCTCC AB 2011022T = NRRL B-59659T).

Chemotherapy in childhood leukemia is associated with late morbidity in leukemic survivors, while certain patient subsets are relatively resistant to standard chemotherapy. It is therefore important to identify new agents with sensitivity and selectivity towards leukemic cells, while having less systemic toxicity. Peptide-based therapeutics has gained a great deal of attention during the last few years. Here, we used an integrative workflow combining mass spectrometric peptide library construction, in silico anticancer peptide screening, and in vitro leukemic cell studies to discover a novel anti-leukemic peptide having 3+ charges and an alpha helical structure, namely HMP-S7, from human breast milk. HMP-S7 showed cytotoxic activity against four distinct leukemic cell lines in a dose-dependent manner but had no effect on solid malignancies or representative normal cells. HMP-S7 induced leukemic cell death by penetrating the plasma membrane to enter the cytoplasm and cause the leakage of lactate dehydrogenase, thus acting in a membranolytic manner. Importantly, HMP-S7 exhibited anti-leukemic effects against patient-derived leukemic cells ex vivo. In conclusion, HMP-S7 is a selective anti-leukemic peptide with promise, which requires further validation in preclinical and clinical studies.

Abstract Quantitative analysis by high-pressure liquid chromatography shows that all commercial samples of elemental sulfur besides S8 contain traces of S7 (up to 0.56%) and in some cases also S6, S9 , and polymeric sulfur (S∞). Pure S8 can be obtained by recrystallization from CS2 . Elemental sulfur minerals also quite often contain traces of S7 (up to 0.3%). Since neither irradiation by daylight at 20 °C nor heating to 90 °C for 41 days did convert α-S8 into S7 , the reactive sulfur molecules Sn (n≠8) are believed to origin from liquid or gaseous sulfur which are known to be complex equilibrium mixtures of many Sn species. Sulfur melts slowly cooled (within 0.6 to 145 h) from 122 to 20 °C in fact contain S7 (minimum 0.2%) and at cooling rates of <24 h also other non-S8 molecules. Solid solutions of S7 in α-S8 have also been prepared by cocrystallization of the compounds from CS2. In contrast to pure α-S8, these solid solutions are pale-yellow at 77 K, and the implications of these findings for the surface composition of Jupiter’s satellite Io and for the mechanical properties of “formed sulfur” (Prills, Rotoform, Slates, etc.) are discussed.

During the past two decades, metabolic dysfunction and concomitant reduction-oxidation reaction (redox) imbalances (i.e., oxidative stress) have been suggested to be associated with numerous age-related chronic diseases. One profound result of metabolic imbalances is endothelial dysfunction, a pathophysiological condition that increases risk of downstream chronic disease consequences. Healthy endothelial function has been positively associated with elevated levels of circulating nitric oxide (NO). Consequently, a natural, plant-based material that may safely increase endogenous NO levels, reduce redox imbalance, and promote improved metabolic response could be of significant interest and benefit. In this first study of its kind, we conducted a longitudinal, randomized, double-blind, placebo-controlled study of S7, a proprietary polyphenol-rich fruit, vegetable, and herb-based material previously reported to reduce reactive oxygen species (ROS) and to increase NO. Specifically, we measured changes in real-time cellular generation of ROS and changes in levels of bioavailable NO (measured as circulating NOHb) in 42 overweight or slightly obese individuals who were recruited into one of three groups: placebo, 25mg of S7, and 50mg of S7. Results suggest that after 90 days of once-daily supplementation, the 25mg and 50mg S7 groups exhibited diminished mitochondrial ROS generation (~54% and ~75%, respectively) compared to placebo, which exhibited a slight increase (&gt;12%) (p = 0.049). Furthermore, circulating NOHb levels significantly increased in the 25mg and 50mg S7 groups (33.87% and 53.43%, respectively) compared to placebo (p &lt; 0.001). Together, these results suggest that long-term daily supplementation of S7 may provide potential benefits related to healthy endothelial function and reduced mitochondrial dysfunction.

The effects of vacuum carburizing under an acetylene atmosphere at 950 and 1000, followed by gas quenching and tempering at various temperatures on the properties of AISI S7 shock-resistant tool steel were studied. As carburized specimens undergo low temperature tempering, the surface hardness of the quenched specimens carburized at 1000 is lower than those of the specimens carburized at 950, due to the large amount of retained austenite in specimens carburized at 1000. Under high temperature tempering, specimens carburized at 1000 have higher surface hardness than specimens carburized at 950. As specimens are tempered in the range between 450 to 550, the surface hardness of carburized specimens show a modest increase due to the secondary hardening effects. According to the fracture toughness data, the toughness of carburized specimens peaked at tempering at 600.

Abstract The photochemical decomposition of pure carbondisulfide as well as of solutions of pure S6 , S7 , S8 , S10 and S12 , respectively, in CS2 at 15 °C on irradiation by a high-pressure mercury lamp (200-600 nm) has been studied by quantitative HPLC analysis of the soluble products. In all cases mixtures of sulfur homocycles Sn (n = 5,6, ...) are formed with S8 , S7 and S6 being the dominating species, but traces of S5 , S9 , S10 and S12 have also been observed in most cases. S5 has been identified for the first time; it is formed in particular in the photolysis of S7 in CS2 . All irradiated sulfur solutions reach more or less the same photostationary equilibrium, but the decomposition of CS2 increases linearly with time and its effects are superimposed on the Sn interconversion reactions.

To investigate phytonutrient accumulation in black raspberries, fruits of `Jewel' and `MacBlack' were harvested at stages from the onset of color development (S1) to ripe fruit (S7). S1–S7 samples were characterized for color reflectance and then frozen at –28 °C within an hour of harvest. Additional ripe fruit were maintained at 20 °C for 3 days to overripen (S8) before freezing. After storage, samples were analyzed for dry weight (DW), total soluble solids (TSS), fructose (FRU), glucose (GLU), and organic acid (ORG) contents; total phenolic (PHE) and anthocyanin (ACY) contents; individual cyanidin glycoside levels (ICG); and antioxidant capacity (FRAP and ABTS) by standard methodology. `Jewel' and `MacBlack' ripened similarly. Chroma values and DW percentage decreased while TSS levels, sugar contents (FRU+GLU), PHE, ACY, the ACY: PHE ratio, and ICG increased with progressive ripening stages (S1–S7). Values of PHE, ACY, and ICG were highly correlated (r < +0.95) with FRAP and ABTS values. ACY levels in S6 fruit were 18% to 23% less than those of S7; lower S6 ACY levels were associated with reduced antioxidant capacity in `MacBlack', but not `Jewel'. Overripened fruit (S8) exhibited increased DW (11% to 25%) and decreased sugar contents (16% to 17%), consistent with moisture and respiratory losses after harvest. After correction for these losses, S7 and S8 levels of PHE, ACY, FRAP, and ABTS were similar in `MacBlack'. However, as `Jewel' overripened, ACY levels and antioxidant activity increased 44% and 22% to 26%, respectively. Our data suggests that significant changes in the antioxidant behavior of black raspberries can occur during the periods surrounding peak ripeness.

For prokaryotes in vitro, 16S rRNA and 20 ribosomal proteins are capable of hierarchical self- assembly yielding a 30S ribosomal subunit. The self-assembly is initiated by interactions between 16S rRNA and three key ribosomal proteins: S4, S8, and S7. These proteins also have a regulatory function in the translation of their polycistronic operons recognizing a specific region of mRNA. Therefore, studying the RNAprotein interactions within binary complexes is obligatory for understanding ribosome biogenesis. The non-conventional RNAprotein contact within the binary complex of recombinant ribosomal protein S7 and its 16S rRNA binding site (236 nucleotides) was identified. UVinduced RNAprotein cross-links revealed that S7 cross-links to nucleotide U1321 of 16S rRNA. The careful consideration of the published RNA protein cross-links for protein S7 within the 30S subunit and their correlation with the X-ray data for the 30S subunit have been performed. The RNA protein crosslink within the binary complex identified in this study is not the same as the previously found cross-links for a subunit both in a solution, and in acrystal. The structure of the binary RNAprotein complex formed at the initial steps of self-assembly of the small subunit appears to be rearranged during the formation of the final structure of the subunit.

<p><strong>Abstract</strong></p><p><strong></strong>Characterization of lines is needed to obtain information about their superiority. Indonesian Tropical Fruit Research Institute conducted inbreeding activities on melon and produced S5 lines generation consisting of eight lines from 2009 till 2011. In inbreeding activities, S6 and S7 lines generation were tested at Sumani Experimetal Station, Tropical Fruit Research Institute, West Sumatra. This study aims to establish a pure strain of melon with the advantages of certain properties and can be proposed as new varieties of open pollinated category. A randomized block design was used in this experiment with ten treatments (eight melon lines, namely 86DH, 86P, Nomani R, 411, 78 K, 86 M, MB3, MB4, and Amanta, Sweet M-10 and Glamour as comparitors), and 3 replications. Each treatment unit consisted of 20 plants. Qualitative data were analyzed descriptively, while quantitative data were analyzed using ANOVA. The observation result of characters of melon lines S6 generation indicated that 86 DH, Amanta (comparator) and MB3 lines have higher fruit weigh between 2,01 kg - 1,69 kg, while for TSS only Nomani R melon lines has TSS values lower than 9 lines. Based on the characters of the fruit flesh color, skin color, and texture of the fruit flesh, lines of 86DH, 78K, Nomani R and 411 were uniform. The observation result of characters of melon lines generation S7 showed that melon lines of 86P has superior character in weight, whilst 86M, 86P and R Nomani had superior character in sweet taste.</p><p><strong>Abstrak</strong></p><p>Karakterisasi galur sangat dibutuhkan untuk mendapatkan informasi tentang keunggulannya. Sejak tahun 2009 sampai 2011 Balai Penelitian Tanaman Buah Tropika melakukan penggaluran melon dan telah menghasilkan delapan galur S5. Dalam kegiatan penggaluran, materi pemuliaan galur generasi S6 dan S7 diuji di kebun percobaan Sumani, Balai Penelitian Tanaman Buah Tropika, Sumatera Barat. Penelitian ini bertujuan untuk membentuk galur murni melon dengan keunggulan sifat-sifat tertentu dan dapat diusulkan sebagai varietas unggul baru kategori open pollinated. Rancangan penelitian yang digunakan ialah Rancangan Acak Kelompok Lengkap dengan 10 perlakuan varietas melon (delapan galur melon yaitu 86DH, 86P, Nomani R, 411, 78 K, 86 M, MB3, MB4, dan pembanding yang sudah adaptif di lokasi penanaman yaitu Amanta, Sweet M-10 dan Glamour) dengan ulangan tiga kali dimana setiap ulangan terdiri atas 20 tanaman. Penelitian dilakukan mulai dari Januari 2012 &amp;ndash; Desember 2013 dengan cara melakukan penanaman galur S6 dan S7 dan karakterisasi morfologi tanaman. Data kualitatif yang dikumpulkan dianalisis secara deskriptif, sedangkan data kuantitatif dianalisis menggunakan Analisis Varian (ANOVA). Hasil pengamatan karakter galur melon generasi S6 menunjukkan bahwa berat buah rata-rata tertinggi diperoleh dari galur 86 DH, Amanta (Pembanding) dan MB3 dengan berat antara 2,01 kg - 1,69 kg, sedangkan untuk TSS selain galur melon Nomani R (MB10), 9 galur melon yang diuji memiliki nilai TSS antara 11.1 &amp;ndash; 12.7 0Brix. Berdasarkan karakter warna daging buah, warna kulit, dan tekstur daging buah, galur 86DH, 78K, Nomani R dan 411mengekpresikan keseragaman. Hasil pengamatan karakter galur melon pada generasi S7 menunjukkan bahwa galur melon 86P unggul pada karakter bobot dan galur 86M, 86P dan Nomani R unggul karakter rasa manis dibandingkan varietas pembanding Glamour. Galur melon 86M, 78K, 411, Nomani R dan MB3 seragam dan stabil untuk semua karakter yang diamati. Galur melon 86DH, 86P dan MB4 masih bervariasi untuk keragaan kulit buah dan warna daging buah.</p>
