    Scrape cell-block technique for fine needle aspiration cytology smears (2000)

    Notes: An inconclusive diagnosis on fine needle aspiration cytology (FNAC) may be due to poor spreading and presence of thick tissue fragments despite aspiration of adequate material. Repeat aspiration may not be possible especially when aspirates of deep seated organs have been obtained by image guided techniques. We have resorted to a ‘scrape cell-block’ (SCB) technique in such cases. In this technique the cellular material on the slides which had already been fixed and stained, was carefully removed by scraping following destaining and then processed as a cell block. SCB interpretation was then compared with the smear diagnosis and histological diagnosis, wherever available. A total of 27 cases were studied. In 12 cases SCB slides added information to the FNAC smears. In 14 cases SCB did not offer any additional information. SCB was inconclusive in one case. Final histological correlation was available in eight cases and the SCB diagnosis was confirmed in six cases, whereas in two cases SCB failed to identify the tumour. Immunocytochemistry (ICC) was done in one case. SCB is a useful technique to make the best use of the available material when reaspiration is difficult.

    Altered keratin expression in buccal mucosal squamous cell carcinoma (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral pathology & medicine 18 (1989), S. 0

    Topics: Medicine
    Notes: Cytokeratin pattern was analyzed in 14 moderately differentiated and 12 well-differentiated squamous cell carcinomas of buccal mucosa by SDS-PAGE, immunoblotting and two dimensional electrophoresis. These were compared with patterns of normal buccal mucosa and surrounding areas whenever possible. Normal buccal mucosa expresses keratin No. 4 (59Kd), 5 (58Kd), 13 (54Kd) and 14 (50Kd). Keratin No. 4 (59Kd) and 14 (50Kd) were expressed by 20 of 26 tumors studied, while many of the tumors did not express keratins No. 5 (58Kd) and 13 (54Kd). Keratin No. 1 (67Kd) and 16 (48Kd) were aberrantly expressed by 9 well-differentiated tumors. Keratin No. 17 (46Kd) and 18 (45Kd) were expressed by 10 and 8 tumors of 14 moderately differentiated tumors. Six tumors which showed involvement of alveolar mucosa, expressed some keratins expressed by its normal counterpart. Their altered expression was consistent with the differentiation pattern as stated earlier. Non-expression of keratins 5 and 13 seems to be the result of malignant transformation and is seen in the majority of tumors, while appearance of aberrant keratins seems to be related more to the degree of differentiation of the tumor.

    Menadione sodium bisulphite: a novel plant defence activator which enhances local and systemic resistance to infection by Leptosphaeria maculans in oilseed rape (2003)

    Notes: Pretreatment of the first true leaves of oilseed rape plants (Brassica napus cv. Bristol) with menadione sodium bisulphite (MSB) locally and systemically induced resistance, as shown by reduced lesion size and number, to infection by the fungal pathogen Leptosphaeria maculans, the causal agent of stem canker. Using a known systemic activator of salicylic acid-dependent PR-1 induction, acibenzolar-S-methyl (BTH; S-methylbenzo[1,2,3]thiadiazole-7-carbothiate) as a comparison, real-time PCR expression analysis of genes encoding a pathogenesis-related protein 1 (PR-1) and an ascorbate peroxidase (APX) demonstrated a systemic enhancement of APX expression in MSB-pretreated plants, with no effect on PR-1 expression, suggesting augmented reactive oxygen species production in MSB-pretreated plants. The results demonstrate MSB to be an effective resistance activator in oilseed rape, and potentially useful for the control of stem canker.

    Primary primitive neuroectodermal tumour of the parotid gland (1998)
    Oxford, U.K. and Cambridge, USA : Blackwell Science Ltd

    Notes: Primitive neuroectodermal tumour (PNET) is a malignant small round cell tumour that exhibits neuroepithelial differentiation. Isolated cases of PNET have been reported in visceral sites such as the kidney, uterus, ovary, testis, urinary bladder and pancreas. We present two cases of PNET of the parotid gland.〈section xml:id="abs1-2"〉〈title type="main"〉Methods and resultsThe first case was a 60-year-old woman, who presented with a parotid swelling of 10 months duration. The second case was a 45-year-old man, who presented with a recurrent temporofacial swelling of 6 months duration. Histological evaluation, in conjunction with immunohistochemistry, confirmed the diagnosis of PNET.〈section xml:id="abs1-3"〉〈title type="main"〉ConclusionsThis is the first documentation of PNET of the salivary gland. The probable origin is from the facial nerve.

    Angiogenesis is redundant for tumour growth in lymph node metastases (2001)
    Oxford UK : Blackwell Science Ltd.
    Histopathology 38 (2001), S. 0 
    Details
    ISSN: 1365-2559
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Angiogenesis is redundant for tumour growth in lymph node metastases Aims: Angiogenesis is essential for the growth of solid tumours. As the role of angiogenesis is unclear in the pathogenesis of primary lymph node (LN) tumours, we wondered whether neoangiogenesis was important in supporting and promoting the growth of tumours in LNs. Methods and results: We investigated 16 cases of squamous carcinoma involving oral cavity (n=9) and larynx/pyriform fossa (n=7), all of whom had lymph node metastases. Sections of the primary tumour, uninvolved mucosa, metastatic LN and nonmetastatic LN were double-immunostained with factor VIII-related antigen and MIB-1. Proliferating blood vessels, i.e. neoangiogenesis, was identified by coexpression of factor VIII-related antigen-stained blood vessels and MIB-1 staining of the endothelial cell nuclei. Counts were performed in an area of 4 mm2. Primary tumours (127–188.7), uninvolved mucosa (54–84.5) and metastatic LNs (123.5–167) had significantly lower vessel counts than nonmetastatic LNs (194–253.9) (P=0.003; P 〈 0.001; P 〈 0.001, respectively). With regard to neoangiogenesis, primary tumours (1.7–5) had significantly higher counts than uninvolved mucosa (0–0.4), nonmetastatic LNs (0–0.4) and metastatic LNs (0.9–2.4) (P 〈 0.001; P 〈 0.001; P=0.047, respectively). Conclusions: Our data suggest that because of the rich native vascularity of lymph nodes, neoangiogenesis is redundant for the growth of metastatic tumour.

    Preionization effects of iso-C4H10 in N2 TE UV lasers (1992)
    Springer

    Notes: Abstract In this paper the ionizing role of isobutane (iso-C4H10) in the operation of a N2TE UV laser is analyzed. Laser pulse width value modifications, different laser wavelengths generated in the 2+ system and voltage pulse period modifications are analysed in order to show that isobutane, in very reduced quantities, generates a preionizing effect that can be higher than that produced by a conventional wire preionization system.
