Abstract Cell pattern and ultrasculpture were examined by light and scanning electron microscopy in bulb tunics of 46 Allium species to determine the diagnostic value of micromorphological characters. The study examined the diversity of these characters, evaluated their usefulness at different taxonomic levels (species, section, subgenus), and considered the results in relation to the recent intrageneric classification of the genus. Detailed characteristics are provided for the investigated species, and taxa showing the presence of calcium oxalate crystals in bulb tunic cells are indicated. The results suggest that several bulb tunic characters are of taxonomic significance in Allium as their variation between specimens of the same species was negligible; they can be useful elements of species descriptions and determination keys. Allium subgenus Allium shows considerable variation of bulb tunic ultrasculpture and hexagonal or elongated cell patterns. Differences in ultrasculpture are sufficient to distinguish species within the Amerallium subgenus. Three subgenera (Anguinum, Butomissa, Reticulatobulbosa) are characterized by fibrous tunics with reticulate ultrasculpture. Rectangular to elliptic cells with thick walls, giving the bulb tunic an almost perforated structure, are characteristic for Allium subgenus Cepa. No specific pattern was found for Allium subgenus Melanocrommyum and Polyprason. The only representative of subgenus Microscordum (Allium monanthum) showed distinct herringbone ultrasculpture. The bulbs of Allium subgenus Rhizirideum representatives can be distinguished by their linear ultrasculpture following the long axis of the elongated cells. Allium bulb tunic ultrasculpture and cell pattern show some degree of variability. These characters are of potential use in taxonomic delimitation, species determination and further study of the relationships between species, particularly in members of subgenus Amerallium.

Good Agreement

For years the separation of carcinoma and sarcoma and the subclassification of sarcomas has been based on the appearance of the tumor cells and their microscopic growth pattern and information derived from certain histochemical and special stains. Although this method of study has produced good agreement among pathologists in the separation of carcinoma from sarcoma, it has given less uniform results in the subclassification of sarcomas. There remain examples of neoplasms of different histogenesis, the classification of which is questionable because of similar cytologic and growth patterns at the light microscopic level; i.e. amelanotic melanoma versus carcinoma and occasionally sarcoma, sarcomas with an epithelial pattern of growth simulating carcinoma, histologically similar mesenchymal tumors of different histogenesis (histiocytoma versus rhabdomyosarcoma, lytic osteogenic sarcoma versus rhabdomyosarcoma), and myxomatous mesenchymal tumors of diverse histogenesis (myxoid rhabdo and liposarcomas, cardiac myxoma, myxoid neurofibroma, etc.)

Geospatial monitoring of leaves variability has been performed for Platanus orientalis L. (Platanaceae) in Hissar Valley of Tajikistan. 17 local populations were clustered in four territorial groups and investigated by 11 morphometric variables and four indices. Six levels of variability were taken in the classification of S.A. Mamaev. All tested parameters were ranked due to the total score of variability levels. It was established, that indicators which have the combination of high, increased, and medium levels of variability, can be recommended for the purpose of geospatial monitoring. In the studied set of variables are two such ones: (1) the ratio of the length of leaf blade to the lengh of petiole, and (2) the petiole lengh. These two indicators reliably respond to point sources of industrial environmental pollution (Aluminum and Cement factories). Six indicators with domination of the middle level of variability, are of diagnostic value to differ loci inside territorial groups of populations. The results of the experiment confirmed, that set of variability levels for 8 of 15 studied parameters has diagnostic matter for geospatial monitoring of environment conditions in Hissar Valley of Tajikistan.

Background Elasticity is an important characteristic of tissue. During an elastography examination, various strain images of lesions are observed, and a suitable classification of strain patterns (SP) may provide vital diagnostic information about lesions. Numerous studies have shown that ultrasound elastography can improve the detection of prostate cancer, but the diagnostic value of SP classification has not yet been fully evaluated. Purpose To investigate the contribution of SP on the characterization of prostate peripheral zone lesions by transrectal real-time tissue elastography (TRTE) in combination with conventional transrectal ultrasonography (TRUS). Material and Methods One hundred and seventy-one patients with suspected prostate cancer underwent TRUS and TRTE examinations. The SPs of the suspicious lesions were classified into five scores by TRTE according to the degree and distribution of strain. All findings were confirmed by transrectal systematic 12-core biopsies and targeted biopsies for suspicious areas detecting by TRUS and/or TRTE. Results One hundred and forty-eight of 171 patients had high-quality TRTE imaging and were included into the study. When a cut-off point of SP score III was used, the area under the receiver-operating characteristic curve (AUC) was, respectively, 0.75 (95% CI: 0.67–0.83), 0.85 (95% CI: 0.78–0.91) and 0.84 (95% CI: 0.77–0.91) for the diagnosis of prostate cancer by TRUS, TRTE and TRTE + TRUS. A linear tendency of SP and Gleason scores was observed in scores III-V. The detection rate of prostate cancer using TRTE-targeted biopsy (75.8%) was significantly higher than that of systematic 12-core biopsy plus TRUS-targeted biopsy (14.5%) ( P = 0.00). Conclusion This study suggests the significant contribution of SP on characterization of prostate peripheral zone lesions and the improvement of TRTE-targeted biopsy on detection of prostate cancer.

AbstractThe possible use of index paths to assess avalanche potential in large avalanche samples was evaluated with probability theory on 56 uncontrolled avalanche paths in Colorado. Results showed the technique yields limited information of little diagnostic value because of low conditional probabilities of joint occurrence and high yearly variance. 90% of pairs tested had probabilities ≦0.20 for a six-year period. Implications for researchers and field personnel are discussed.

In this paper, we introduce a new modality for capturing body postures and social behaviour. Vice versa, we propose a new application area for on-body textile sensors. We have developed “smart trousers” with embedded textile pressure sensors that allow for classification of a large variety of postural movements as well as interactional states. Random Forest models are used to investigate those. Here, we give an overview of the research conducted and discuss potential use cases of the presented design.

Normal Controls

Background: The aim of this study was to identify novel microRNAs for potential use in the diagnosis of pancreatic cancer (PaC). Methods: A total of 1063 serum samples from 303 patients with PaC were collected, and the expression level of miR-25 was measured using quantitative real-time PCR (qRT-PCR). Results: We found that miR-25 had significant diagnostic value for the differential diagnosis of PaC in normal controls with an AUC (the area under the ROC curve) of 0.915 (95% CI: 0.893-0.937) that was significantly higher compared with an AUC of 0.725 for serum tumor marker carcinoembryonic antigen (CEA) and an AUC of 0.844 for CA19-9. Conclusions: These data suggest that serum miR-25 has strong potential as a novel biomarker for the early detection of PaC.
