Banana (Musa sp) is a plant that has good nutrion, mineral, vitamin A, B complex, vitamin C, and vitamin B6. Germplasm diversity of local banana in Bangka has never been identified. Research about germplasm diversity of banana in Bangka Island need to maintain germplasm of Bangka local banana. This research was conducted in Bangka Island. Characterization of banana fruit germplasm includes on qualitative and quantitative traits. Analysis of morphological relationship of banana fruit germplasm used UPGMA. Exploration result obtained 22 germplasms of Bangka local banana. The result of relationship analysis showed four clusters at 0,40 (40%) coefficient. Cluster one consists of Udang germplasm. Cluster two consists of Jernang and Rotan germplasm. Cluster three consists of Wei, Kapal and Abu germplasm. Cluster four consists of Madu Manis, Madu Keling, Gambur, Jambi, 40 Hari, Bawang, Geda, Tematu, Serindit, Masak Ijau, Rejang, Madu Pulau, Kecit Lantai, Susu, Gede and Lilin germplasm.

Germplasm diversity of local taro in Bangka as genetic resources for plant breeding purposes is still unknown. This research aimed to provide information on Bangka Taro’s variability and relationship for plant breeding programs. This research was conducted in December 2017 until February 2018. Characterization of the germplasm was performed on qualitative and quantitative parameters. Analysis of morphological relationships used the UPGMA method. Exploration obtained 27 germplasm of Bangka local taro. The results of the morphological relationship analysis showed nine clusters at a 0.57 coefficient (57%). Cluster one consisted of Tungkuk, Sayur, Hitam/Nyatoh, Rakit Hijau, Lilin, and Cantik Manis accessions. Cluster two consisted of Rakit Hitam accession. Cluster three consisted of Ganjung, Trans 2, Sungai Tebuk and Trans 1 accessions. Cluster four consisted of Sayang Anak, Pak Ugo and Trans 3 accessions.

The aim of this work was to evaluate the cytosolic contents of hyaluronic acid (HA) and cathepsin D (CatD) in gastric carcinomas and their possible relationships with the clinicopathological parameters of the tumors. Our study demonstrated a wide variability in the cytosolic levels of HA (mean ± SEM: 3748 ± 411 ng/mg protein) and cathepsin D (52 ± 4 pmol/mg protein) in the tumors of 78 gastric cancer patients. In addition, the tumoral contents of HA and CatD were significantly higher (p<0.005) in diffuse type (HA: 6027 ± 1099 ng/mg protein; CatD: 75 ± 13 pmol/mg protein) than in intestinal type (HA: 2735 ± 242 ng/mg protein; CatD: 42±3 pmol/mg protein) carcinomas. These data suggest that both markers may contribute to the biological characterization of gastric carcinomas.

Traditional Filuferru is an ancient spirit from Sardinia, Italy, usually obtained from the distillation of wine or grape marc. In this contribution, the results of the first chemical characterization of a wide number of craft Filuferru samples has been accomplished in terms of evaluation of the alcoholic strength, qualitative and quantitative GC-MS analysis of the volatile composition of the distillate, and its trace element composition by means a ICP-MS method. Both instrumental methods have been validated and applied on 21 craft samples of Filuferru, whereas one sample of commercial distillate has been analyzed for comparison purposes. Alcoholic strength ranged between 41.0 and 62.4% (v/v). Sixty volatile compounds were identified and ten of them have been quantified. Analogies and differences with Grappa (i.e. the Italian distilled spirit most close to Filuferru) have been highlighted in the qualitative and quantitative profile of this matrix. Often meaningful amounts of acetaldehyde, ethyl acetate, dietyl acetal and acetic acid were measured. Elemental analysis, performed on toxic, non-toxic elements and oligoelements, 18 in total, revealed a wide variability of concentrations in both analytes and samples. High concentrations of Cu are sometimes evidenced, likely caused by losses from the distillation apparatus. The principal components analysis (PCA) allowed the differentiation of the ten volatile compounds quantified in two groups: the former, described mainly by PC1, constituted by acetic acid, ethyl acetate, dietyl acetal and acetaldehyde, and the second, described by PC2, constituted by 1-propanol, 2-methyl-1-propanol, the two coeluiting isomers 2-methyl-1-butanol and 3-methyl-1-butanol,1-hexanol, 2-phenylethanol and 2,3-butanediol. Data obtained may be useful in order to establish a regulation for the production of high-quality traditional Filuferru from Sardinia.

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

AbstractS-box is the basic component of symmetric cryptographic algorithms, and its cryptographic properties play a key role in security of the algorithms. In this paper we give the distributions of Walsh spectrum and the distributions of autocorrelation functions for (n + 1)-bit S-boxes in [12]. We obtain the nonlinearity of (n + 1)-bit S-boxes, and one necessary and sufficient conditions of (n + 1)-bit S-boxes satisfying m-order resilient. Meanwhile, we also give one characterization of (n + 1)-bit S-boxes satisfying t-order propagation criterion. Finally, we give one relationship of the sum-of-squares indicators between an n-bit S-box S0 and the (n + 1)-bit S-box S (which is constructed by S0).

Graphene, a relatively new two-dimensional (2D) nanomaterial, possesses unique structure (e.g. lighter, harder, and more flexible than steel) and tunable physicochemical (e.g. electronical, optical) properties with potentially wide eco-friendly and cost-effective usage in biosensing. Furthermore, graphene-related nanomaterials (e.g. graphene oxide, doped graphene, carbon nanotubes) have inculcated tremendous interest among scientists and industrials for the development of innovative biosensing platforms, such as arrays, sequencers and other nanooptical/biophotonic sensing systems (e.g. FET, FRET, CRET, GERS). Indeed, combinatorial functionalization approaches are constantly improving the overall properties of graphene, such as its sensitivity, stability, specificity, selectivity, and response for potential bioanalytical applications. These include real-time multiplex detection, tracking, qualitative, and quantitative characterization of molecules (i.e. analytes [H2O2, urea, nitrite, ATP or NADH]; ions [Hg2+, Pb2+, or Cu2+]; biomolecules (DNA, iRNA, peptides, proteins, vitamins or glucose; disease biomarkers such as genetic alterations in BRCA1, p53) and cells (cancer cells, stem cells, bacteria, or viruses). However, there is still a paucity of comparative reports that critically evaluate the relative toxicity of carbon nanoallotropes in humans. This manuscript comprehensively reviews the biosensing applications of graphene and its derivatives (i.e. GO and rGO). Prospects and challenges are also introduced.
