- Abstract
A series of 65 cases of different histological types of breast carcinoma was investigated for the immunohistochemical location of the estrogen receptor-related, 29 kD phosphoprotein using the ER-D5 monoclonal antibody.The ER-D5 response is heterogeneous in relation to some therapeutic limitations and is correlated with histopathological features of the tumors and survival. The main parameters for evaluation of breast cancers are reviewed, both those that are statistically correlated and those that are not apparently always correlated but are known to have considerable biological meaning, such as the ER-status of tumors.

The traditional prognostic factors, including stage of disease and tumour grade, have shown a limited prognostic significance and an inability to predict clinical response to specific treatment in patients with laryngeal squamous-cell carcinoma. More recent data suggest that cell kinetics indices, DNA-ploidy, lysosomal cysteine proteinase expression and genetic changes of both tumour suppressor genes and proto-oncogenes may be considered as reliable and reproducible indicators of biological aggressiveness in these patients. Moreover, the frequency of different genetic alterations suggests that several pathways are involved in the genesis of these neoplasias and, in particular, it is very probable that p-53 expression and PCNA indices (increased in normal mucosa and preinvasive lesions) may constitute more important biomarkers for the early steps of laryngeal carcinogenesis.

SB would like to thank Tara Murphy, Martin Bell, Paul Hancock, Keith Bannister, Chris Blake and Bing Zhang for useful discussions., We report the discovery of four Fast Radio Bursts (FRBs) in the ongoing SUrvey for Pulsars and Extragalactic Radio Bursts at the Parkes Radio Telescope: FRBs 150610, 151206, 151230 and 160102. Our real-time discoveries have enabled us to conduct extensive, rapid multimessenger follow-up at 12 major facilities sensitive to radio, optical, X-ray, gamma-ray photons and neutrinos on time-scales ranging from an hour to a few months post-burst. No counterparts to the FRBs were found and we provide upper limits on afterglow luminosities. None of the FRBs were seen to repeat. Formal fits to all FRBs show hints of scattering while their intrinsic widths are unresolved in time. FRB 151206 is at low Galactic latitude, FRB 151230 shows a sharp spectral cut-off, and FRB 160102 has the highest dispersion measure (DM = 2596.1 ± 0.3 pc cm−3) detected to date. Three of the FRBs have high dispersion measures (DM > 1500 pc cm−3), favouring a scenario where the DM is dominated by contributions from the intergalactic medium. The slope of the Parkes FRB source counts distribution with fluences >2 Jy ms is α=−2.2+0.6−1.2 and still consistent with a Euclidean distribution (α = −3/2). We also find that the all-sky rate is 1.7+1.5−0.9×103 FRBs/(4π sr)/day above ∼2Jyms and there is currently no strong evidence for a latitude-dependent FRB sky rate., The Parkes radio telescope and the Australia Telescope Compact Array are part of the Australia Telescope National Facility which is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO. Parts of this research were conducted by the Australian Research Council Centre of Excellence for All-sky Astrophysics (CAASTRO), through project number CE110001020. The GMRT is run by the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research. VLAis run by theNational Radio Astronomy Observatory (NRAO).

The tick feeding process in humans and its effects on the host skin have been studied histologically on specimens of tick bites, some of which included the attached parasite, and on ticks extracted from lesions or caught in the wild. The specimens, included in paraffin, were stained with hematoxylin-eosin, orcein–Giemsa for elastic fibers, periodic acid-Schiff for polysaccharides, Weigert method for fibrin, Warthin-Starry stain for spirochetes, and Bodian’s method for nerve fibers. The mouthparts of the attached ticks were embedded in a cement cone, with the chelicerae and the hypostome lining the oral canal, while the basis capituli contained the pharynx with its anti-reflux valves, the hypopharynx with its dilating musculature, and the muscles serving the chelicerae. The structure of the motor muscles, of the inner organs, of the central nervous system, and the cuticle with its nerve endings were also visible. The superficial and the mid dermis underlying the cone was replaced by a lose network of fibrin, endothelial linings, and residual collagen bundles, soaked with edema and blood. The dilated small vessels showed gaps of the walls with blood extravasation, and endothelial proliferation, sometimes associated to neutrophilic and eosinophilic vasculitis. A dense neutrophilic infiltrate was present beneath the apex of the cone. The lesions observed after the tick removal included: Erythema Chronicum Migrans – like changes, foreign body granuloma, cutaneous T- and the B-cell lymphoid hyperplasia, and alopecia with involvement of the permanent portion of the hair follicles and hyperplasia of their fibrous sheaths. The acute changes, similarly to the “cavity” described in the animal hosts, result from a “vacuum pump” action performed by the mouthparts, together with the effect of proteinases, vaso-dilators, anticoagulants, immunosuppressants and antiinflammatory molecules contained in the regurgitated saliva. A persistent reaction of the host to these chemicals and/or to possible infectious agents accounts for the subacute and chronic lesions.

Ion channels regulate cell proliferation, differentiation, and migration in normal and neoplastic cells through cell-cell and cell-extracellular matrix (ECM) transmembrane receptors called integrins. K+ flux through the human ether-a-go-go-related gene 1 (hERG1) channel shapes action potential firing in excitable cells such as cardiomyocytes. Its abundance is often aberrantly high in tumors, where it modulates integrin-mediated signaling. We found that hERG1 interacted with the beta(1) integrin subunit at the plasma membrane of human cancer cells. This interaction was not detected in cardiomyocytes because of the presence of the hERG1 auxiliary subunit KCNE1 (potassium voltage-gated channel subfamily E regulatory subunit 1), which blocked the beta(1) integrin-hERG1 interaction. Although open hERG1 channels did not interact as strongly with beta(1) integrins as did closed channels, current flow through hERG1 channels was necessary to activate the integrin-dependent phosphorylation of Tyr(397) in focal adhesion kinase (FAK) in both normal and cancer cells. In immunodeficient mice, proliferation was inhibited in breast cancer cells expressing forms of hERG1 with impaired K+ flow, whereas metastasis of breast cancer cells was reduced when the hERG1/beta(1) integrin interaction was disrupted. We conclude that the interaction of beta(1) integrins with hERG1 channels in cancer cells stimulated distinct signaling pathways that depended on the conformational state of hERG1 and affected different aspects of tumor progression.

The p16INK4a gene, localized within chromosome 9p21, has been identified as a cyclin-dependent kinase inhibitor and may negatively regulate the cell cycle acting as a tumor suppressor. Genetic alterations involving the 9p21 region are common in human cancers. A consecutive series of 64 untreated patients (median of follow up 53 months) undergoing surgical resection for locally advanced laryngeal squamous-cell carcinomas (LSCCs) has been studied prospectively. Our purpose was to investigate p16 alterations (9p21 allelic loss, hypermethylation and point mutations) and their possible association with clinico-pathological data and flow cytometric variables (DNA-ploidy and S-phase fraction (SPF)), and to determine the possible prognostic role of this gene in these tumors. PCR-based techniques were used for investigating 9p21 loss of heterozygosity (LOH) and methylation promoter status of the p16 gene. p16 mutations were detected by PCR-SSCP (single strand conformation polymorphism) and sequencing. 9p21 LOH was detected in 16/62 (26%) informative tumors, point mutations in 5% (3/64) and hypermethylation in 9% (6/64) of the cases. p16 alterations were significantly associated with high SPF and DNA-aneuploidy. By univariate analysis, poor histologic differentiation, stage IV, DNA-aneuploidy and p16 point mutations proved to be significantly related to quicker relapse, whereas these same factors, and in addition high SPF, 9p21 LOH and any p16 alterations were significantly related to shorter overall survival. By Cox proportional hazards analysis only histologic grade (G3) and p16 point mutations were independently related to both disease relapse and death. Our study has identified p16 point mutations as important biomolecular indicators in LSCCs. © 2002 Wiley-Liss, Inc.

It is essential to reach a better understanding of "flat epithelial atypia/columnar cell lesions" (FEA/CCLs) in breast core biopsies. Our aim was to explore their biological nature, in order to predict the likelihood of an upgrade to carcinoma. "Cytological grading" has been specially focused, in view of its possible utility in the choice of management. One hundred thirty of a total of 900 cases core needle (CN)/vacuum-assisted biopsies (VABs), with diagnoses of "hyperplasia" and "atypia" were retrospectively re-evaluated. Pathological findings of further excision biopsies (FEBs) performed in 40/75 patients with follow-up were compared with the previous diagnoses. In all cases, both Ki-67 and c-kit immunoreactivities were explored and compared with both normal breast tissues and subsequently documented cancers, with special reference to the hyperplastic FEA/CCLs, with "mild" atypia (FEA/CCHAm). Sixteen cases were re-diagnosed as "usual ductal hyperplasia" (UDH), 60 as "columnar cell hyperplasia" (CCH), and 54 as FEA/CCHA, 30 of which FEA/CCHAm and 24 FEA/CCHAh (with high atypia). Significantly, the Ki-67 index proved to be on the increase and c-kit expression on the decrease in FEA/CCHA lesions, mainly in the FEA/CCHAh group and in the subsequently observed cancers, compared with either benign tissues or the FEA/CCH cases. It was also significant that most of the carcinomas were found in FEBs within the FEA/CCHAh group. In this study cytological grading, together with Ki-67 and c-kit indices, proved to be helpful in FEA/CCLs evaluation. With regard to FEA/CCHAm lesions, an adequate surveillance appears to be a more appropriate management tool than FEB, as a result of their biological nature and behavior.

A striking feature of cellular blue nevus consists in the presence, in its histologic picture, of numerous hypertrophic nerves and nerve-like figures, positive for histochemical and immunohistochemical methods for nerve fibers and myelin sheaths. These findings, first described in Masson's original article and repeatedly highlighted in the past for their possible histogenetic significance, are currently considered as merely coincidental. However, the thin conventional histologic sections, catching only short tracts of the nerves, preclude a correct observation of their route and do not allow us to verify if there is an architectural relationship between them and the nevus as a whole. With this aim, we observed a few specimens of cellular blue nevus on digitally overlapped images of contiguous 25-microm-thick sections, processed with Winkelmann's technique of silver impregnation for nerve fibers, which supplied an overall, 3-dimensional view of the lesions and the nerves running through them. In these images, the lobular form of the nevus could be seen gathering around a branching hypertrophic nerve, whose stem stretched vertically from the depth to the most superficial tract of the lesion. The nevus cell aggregates invested the stem and the limbs individually, and these followed the curvilinear contour of the nevus lobules. Our images represent evidence of a preferential perineural aggregation of cellular blue nevus, at least in its lobular form. This indicates that the numerous nerves and the neuroid figures, observed in detail-but within a limited perspective- in the conventional sections, are not merely coincidental and they could indeed be a sign of neural differentiation and/or a clue to the possible neural origin of the nevus.

A retrospective histological and immunohistochemical study has been carried out in 25 cases of tick bites recorded in our Departments. The samples that included an attached tick showed a cement cone anchoring the mouthparts to the skin and a blood-soaked, spongiform appearance of the superficial dermis, with a mild neutrophilic and eosinophilic infiltration. The vessels displayed a loose multilayered endothelial proliferation, with plump endothelia, permeated with erythrocytes. A few of them were severed, allowing copious blood extravasation. The established lesions included the following: erythema chronicum migrans-like cases, foreign body granulomas-sometimes containing remnants of the mouthparts-cutaneous lymphoid hyperplasia, either of the T-cell or the B-cell type, and tick-bite alopecia. In both the T-cell and B-cell pseudolymphomas, several vessels showed concentric endothelial and perithelial proliferation similar to that seen in the acute lesions. In the tick-bite alopecia, a lymphocytic infiltrate attacked the permanent portion of the hair follicles, whose reaction was a noticeable hyperplasia of the fibrous sheaths, although only a minority of the hairs was destroyed. The observed alterations are specific in the acute lesions and in the alopecia, where they directly arise as a result of the interactions between the host's tissues and the antihemostatic, anti-inflammatory, and immunomodulatory chemicals contained in the tick saliva. In the other lesions, the changes seem less characteristic, although the fragments of mouthparts and the special vascular changes provide a clue to their etiology.

Background: Gastric cancer (GC) development is a multistep process, during which numerous alterations accumulate in nuclear and mitochondrial DNA. A deficiency of repair machinery brings about an accumulation of errors introduced within simple repetitive microsatellite sequences during replication of DNA. Aberrant methylation is related to microsatellite instability (MSI) by the silencing of the hMLH1 gene. The aim of this study is to investigate a possible relationship between the RUNX3 promoter methylation, nuclear microsatellite instability (nMSI) and mitochondrial microsatellite instability (mtMSI), in order to clarify its biological role in GC. Patients and methods: nMSI and mtMSI were evaluated in a consecutive series of 100 GC patients. For the analysis of the nMSI, we followed the National Cancer Institute guidelines. mtMSI was assessed by analyzing a portion of the displacement-loop region. The aberrant methylation of RUNX3 was analyzed in 40 GC patients by methylation-specific PCR. Results: Overall, 55% of GC demonstrated methylation of the RUNX3 promoter; 82% of GC was classified as stable microsatellite instability, 5% as low-level microsatellite instability and 13% as high-level microsatellite instability (MSI-H); mtMSI was detected in 11 % of GC. A significant association was found between mtMSI and tumor-node-metastasis staging, furthermore an interesting association between MSI-H status, mtMSI and RUNX3 methylation. Conclusion: These data suggest that RUNX3 is an important target of methylation in the evolution of mtMSI and nMSI-H GC.

Reelin is a glycoprotein that plays a critical role in the regulation of neuronal migration during brain development and, since reelin has a role in the control of cell migration, it might represents an important factor in cancer pathology. In this study, 66 surgical specimens of prostate cancer were analyzed for reelin expression by immunohistochemical method. The reelin expression was correlated with Gleason score and individual Gleason patterns. Reelin expression was found in 39% prostate cancers. Stromal tissues, normal epithelial cells and prostate intraepithelial neoplasia (PIN) of any grade around and distant from cancer were always negative for reelin. Reelin was found in malignant prostatic epithelial glands of 50% cases Gleason score 10, 52% Gleason score 9, 56% Gleason score 8, 18% Gleason score 7, while no sample of prostate cancers with Gleason score 6 showed reelin expression (P=0,005). As reelin staining is frequently found in high Gleason score prostate cancers, we explored whether reelin expression is influenced by single Gleason patterns. While Gleason 3 pattern did not show reelin immunoreactivity, reelin expression was found in 35% Gleason 4 patterns and 45% Gleason 5 patterns (P

The putative role of TP53 and p16INK4A tumor suppressor genes and Ras oncogenes in the development and progression of salivary gland neoplasias was studied in 28 cases of pleomorphic adenomas (PA), 4 cases of cystic adenocarcinomas, and 1 case of carcinoma ex-PA. Genetic and epigenetic alterations in the above genes were analyzed by Polymerase Chain Reaction/Single Strand Conformational Polymorphism (PCR/SSCP) and sequencing and by Methylation Specific-PCR (MS-PCR). Mutations in TP53 were found in 14% (4/28) of PAs and in 60% (3/5) of carcinomas. Mutations in H-Ras and K-Ras were identified in4%(1/28) and7% (2/28) of PAs, respectively. Only 20% (1/5) of carcinomas screened displayed mutations in K-Ras. p16INK4A promoter hypermethylation was found in 14% (4/28) of PAs and 100% (5/5) carcinomas. All genetic and epigenetic alterations were detected exclusively in the epithelial and transitional tumor components, and were absent in the mesenchymal parts. Our analysis suggests that TP53 mutations and p16INK4A promoter methylation, but not alterations in the H-Ras and K-Ras genes, might be involved in the malignant progression of PA into carcinoma. J.

Background Methylation of the p16 promoter is one of the most frequent mechanisms of gene inactivation; its incidence is extremely variable according to the type of tumor involved. Our purpose was to analyze the hypermethylation of the p16 promoter in laryngeal squamous cell carcinomas (LSCC), salivary gland (SG) tumors and in colorectal cancer (CRC), to detect any possible association with the clinicopathological features and to determine the prognostic significance of the p16 gene in the tumors analyzed. Patients and methods The hypermethylation of the p16 promoter was prospectively analyzed, by MSP, in a consecutive series of 64 locally advanced LSCC patients, in a consecutive series of 33 SG tumor patients and in a consecutive series of 66 sporadic CRC patients. Results Hypermethylation was observed in 9% of the LSCC cases, in all cases of SG cancer and in 21% of the CRC cases. No significant association was observed between p16 hypermethylation and clinicopathological variables in all the tissue samples analyzed. Moreover at univariate analysis p16 mutations were not independently related at disease relapse and death in LSCC and CRC. Conclusions The results of this study suggest that the lack of p16 function could happen in advanced stage of SG tumors.

Genotype analysis is becoming more and more useful in clinical practice, since specific mutations in tumors often correlate with prognosis and/or therapeutic response. Unfortunately, current molecular analytical techniques often require time-consuming and costly steps of analysis, thus making their routine clinical use difficult. Moreover, one of the most difficult problems arising during tumor research is that of their cell heterogeneity, which depends on their clear molecular heterogeneity. SSCP analysis discriminates by means of aberrant electrophoresis migration bands, mutated alleles which may represent as little as 15-20% of their total number. Nevertheless, in order to identify by sequencing the type of alteration revealed by this technique, only the mutated allele must be isolated. The advent of laser microdissection is a procedure which easily solves these problems of accuracy, costs, and time. The aims of this study were to perfect the system of laser pressure catapulting (LPC) laser microdissection for the assessment of the mutational status of p53 and k-ras genes in a consecutive series of 67 patients with colorectal carcinomas (CRC), in order to compare this technique with that involving hand-dissection and to demonstrate that since the LPC system guarantees more accurate biomolecular analyses, it should become part of clinical routine in this field. The LPC-system was perfected with the use of mineral oil and the LPC-membrane. To compare the techniques of hand- and LPC-microdissection, alcohol-fixed, paraffin-embedded tissue from 67 cases of CRC were both hand- and laser-microdissected. In either case, dissected samples were analyzed by SSCP/sequencing and direct sequencing for k-ras and p53 gene mutations. LPC-microdissection made it possible to pick up mutations by direct sequencing or SSCP/sequencing, whereas hand-microdissection mutations were identified only by means of SSCP followed by sequencing; direct sequencing did not reveal any mutation. In the 67 patients examined by either method, 36% (24/67) showed p53 mutations, 32 of which identified. Seventy-eight percent (25/32) were found in the conserved areas of the gene, while 12% (4/32) were in the L2 loop, 50% (16/32) were in the L3 loop, and 12% (4/32) in the LSH motif of the protein. Moreover, of the 67 cases examined, 40% (27/67) showed mutations in k-ras, with a total of 29 mutations identified. Of these, 14 (48%) were found in codon 12 and 15 (52%) in codon 13. The modifications which we brought to the LPC system led to a vast improvement of the technique, making it an ideal substitution for hand-microdissection and guaranteeing a considerable number of advantages regarding facility, accuracy, time, and cost. Furthermore, the data obtained from the mutational analyses performed confirm that the LPC system is more efficient and rapid than hand-microdissection for acquiring useful information regarding molecular profile and can therefore be used with success in clinical routine.

Summary We report that the mitochondrial chaperone TRAP1, which is induced in most tumor types, is required for neoplastic growth and confers transforming potential to noncancerous cells. TRAP1 binds to and inhibits succinate dehydrogenase (SDH), the complex II of the respiratory chain. The respiratory downregulation elicited by TRAP1 interaction with SDH promotes tumorigenesis by priming the succinate-dependent stabilization of the proneoplastic transcription factor HIF1α independently of hypoxic conditions. These findings provide a mechanistic clue to explain the switch to aerobic glycolysis of tumors and identify TRAP1 as a promising antineoplastic target., Graphical Abstract, Highlights • The mitochondrial chaperone TRAP1 is required for neoplastic growth • TRAP1 binds to and inhibits succinate dehydrogenase, downregulating cell respiration • TRAP1 stabilizes HIF1α in a pseudohypoxic way by increasing intracellular succinate • TRAP1-dependent induction of HIF1α is required for tumor cell growth

The gene Nm23, which encodes for a nucleoside diphosphate kinase, has been defined as a metastasis-suppressor gene because of the inverse correlation between its expression and the metastatic capacity of the tumor cells. For colorectal cancer, however, the findings are equivocal. The aim of our study was to assess, in 160 patients undergoing surgery for colorectal cancer (CRC), the expression of the Nm23-H1 protein and to evaluate its possible associations with traditional clinicopathologic variables, with DNA-ploidy and proliferative activity (S-phase fraction, SPF), and with disease-free and overall survival of patients. Nm23-H1 expressions were evaluated on paraffin-embedded tissue by immunohistochemistry; DNA-ploidy and SPF on frozen tissue by flow-cytometric analysis. The median follow-up time in our study group was 71 months (range 34-115 months). No association was observed between Nm23-H1 protein expression and clinicopathological variables, S-phase fraction and DNA-ploidy. Furthermore, no significant differences were observed in the survival of patients with either moderate or strong Nm23-H1 expression. The major significant predictors for both disease relapse and death were advanced Dukes' stage, DNA aneuploid tumors and high SPF, while lymphohematic invasion was the only independent factor for relapse and non-curative resection for death. Our results indicate that Nm23-H1 activity is tissue-specific and that in CRCs the expression of the protein is not associated with tumor progression and patient prognosis, although further studies are required in order to throw more light on the possible clinical significance of the overexpression of the protein Nm23-H1 in such tumors.

To study GP-170 in superficial bladder cancer at initial diagnosis and at recurrence and to evaluate if intravesical chemoprophylaxis modifies the expression of GP-170 in tumor recurrences. GP-170 was retrospectively assessed in 160 patients affected by primary superficial transitional cell carcinoma of the bladder and followed for up to 10 years. Eighty-four patients (52.5%) recurred after transurethral resection (TUR). Adjuvant intravesical chemotherapy after TUR was adopted in 52 patients. The correlations between GP-170 and G-grade, T-category, risk of recurrence and of progression, and adoption of adjuvant intravesical chemotherapy were investigated. The correlations between variations in grade and stage at recurrence and modifications in GP-170 expression were also studied. No significant correlation between GP-170 expression and G-grade and T-category was found. A significant correlation was detected between GP-170 expression and recurrence (P=0.0383). It showed a biphasic pattern, i.e., tumors that did not express GP-170 had a higher recurrence rate, but high GP-170 levels were also associated with an increasing risk of recurrence. Intravesical chemotherapy did not induce significative variations in GP-170 expression. No correlation was found between progression and GP-170. GP-170 seems to be an independent prognostic factor for recurrence in superficial bladder tumors. A negative GP-170 pattern and high levels of GP-170 are associated with an increasing risk of recurrence but have no impact upon progression. In our experience, GP-170 is neither induced nor modified by intravesical chemotherapy, although it might represent a factor of chemoresistance when strongly expressed.

Purpose: The aim of this study was to determine TP53 and NM23-H1 immunoreactivity, DNA ploidy, and S-phase fraction (SPF) in a series of 160 patients undergoing resective surgery for primary operable colorectal cancer (CRC) and to establish whether these alterations have any clinical value in predicting CRC patients' prognosis. Methods: TP53 and NM23-H1 expressions were evaluated on paraffin-embedded tissue by immunohistochemistry and DNA-ploidy and SPF on frozen tissue by flow-cytometric analysis. Results: The median follow-up time in our study group was 71 months (range 34-115 months). P53 protein expression was associated with distal tumors (P < 0.05) and DNA aneuploid tumors (P < 0.05) tumors. DNA-aneuploidy was associated with distal tumors (P < 0.01), histological grade (G3) (P < 0.05), advanced Dukes' stage (C and D) (P < 0.01), lymph node metastases (P < 0.01) and high SPF (> 18.3%) (P < 0.01). The major significant predictors for both disease relapse and death were advanced Dukes' stage, DNA-aneuploidy, and high SPF, while lymphohematic invasion was the only independent factor for relapse and non-curative resection for death. Conclusions: Our results indicate that DNA aneuploidy and high SPF are associated in CRC with a poor clinical 5-year outcome, while in contrast the prognostic role of TP53 and NM23-H1 expression is still to be clarified.

p53 alterations are considered the most common genetic events in many types of neoplasms, including colorectal carcinoma (CRC). These alterations include mutations of the gene and/or overexpression of the protein. The aim of our study was to assess whether in 160 patients undergoing resective surgery for primary operable CRC there was an association between p53 mutations and protein over-expression and between these and other biological variables, such as cell DNA content (DNA-ploidy) and S-phase fraction (SPF), and the traditional clinicopathological variables. p53 mutations, identified by PCR-SSCP-sequencing analysis, were found in 68/160 patients (43%) and positive staining for p53 protein, detected with the monoclonal antibody DO-7, was present in 48% (77/160) of the cases, with agreement of 57% (91/160). In particular, a significant association was found between increased p53 expression and genetic alterations localized in the conserved regions of the gene or in the L3 DNA-binding domain and the specific type of mutation. Furthermore, both overexpression of p53 and mutations in the conserved areas of the gene were found more frequently in distal than in proximal CRCs, suggesting that they might be "biologically different diseases." Although p53 mutations in conserved areas were associated with flow cytometric variables, overexpression of p53 and mutations in its L3 domain were only related respectively to DNA-aneuploidy and high SPF. These data may reflect the complex involvement of p53 in the different pathways regulating cell-cycle progression. In conclusion, the combination of the mutational status and immunohistochemistry of p53, and flow cytometric data may provide an important insight into the biological features of CRCs.

BACKGROUND The prognostic value of DNA ploidy, S-phase fraction (SPF) and K-ras-2 mutations in gastric carcinoma (GC) has not yet been clearly defined. The aim of this study was to clarify the association between biomolecular variables, tumor characteristics, and clinical outcome in GC patients. METHODS Resected specimens from a consecutive series of 69 patients with GC who underwent potentially curative surgery were studied prospectively. DNA ploidy and SPF were assessed by flow cytometry on multiple frozen tumor samples, whereas K-ras-2 mutations were detected by polymerase chain reaction followed by single-strand conformation polymorphism. All the patients involved in this study were followed up for a mean of 95 months. RESULTS DNA aneuploidy was present in 72% of the cases (50 of 69), whereas 10% of these (5 out of 50) showed multiclonality. Mutations of K-ras-2 were detected in 8% of the tumors (5 of 63). Both DNA ploidy and SPF were associated with TNM stage (American Joint Committee on Cancer [AJCC] staging system) and node status. Moreover, DNA aneuploidy was significantly related to high SPF. K-ras-2 mutations were not associated with clinicopathologic variables or flow cytometric indicators. At univariate analysis, advanced TNM stage, node involvement, diffuse histotype, depth of invasion, DNA aneuploidy, and high SPF proved to be significantly related to quicker tumor relapse and to shorter overall patient survival. With multivariate analysis, DNA aneuploidy, high SPF, and depth of invasion were related to risk of tumor relapse and patient death, whereas diffuse histotype was independently related to patient risk of tumor relapse. CONCLUSIONS DNA ploidy and SPF, when associated with clinicopathologic staging, might be useful for the identification of GC patients who have different risks for death or relapse of disease.

Breast neoplasms diagnosi ,Surgery ,Biopsy, needle method ,Stereotaxic technique - Abstract
Background and aims. The increasingly frequent use of mammography for the early diagnosis of breast cancer and the consequent identification of mammary lesions at a preclinical stage raises the fundamental problem of the differential diagnosis between non-suspected non-palpable lesions (NPL) which can therefore be monitored over time and suspected NPL or definite carcinoma requiring histological confirmation and surgical biopsy. The diagnostic accuracy of mammography alone is not sufficiently high to differentiate benign lesions from malignant or strongly suspected ones. The use of surgical biopsy in the event of suspected NPL could be significantly reduced by the use of stereotaxic cytology which would improve the diagnostic accuracy of mammography. Methods. The study refers to 72 suspected NPL undergoing surgical biopsy after having performed stereotaxic cytology on a sample taken with a dedicated mammographic device (Mammotest- TRC). Results. The rate of inadequate samples for correct cytological evaluation was 16.1%. Of the 72 NPL undergoing surgical biopsy, 40 (55.5%) were found to be carcinomas and 32 (44.5%) were benign lesions. The sensitivities of mammography alone and cytology alone in identifying infraclinical breast carcinoma were respectively 0.85 and 0.95. If the results of the two methods were evaluated together, the level of sensitivity was 0.98. Conclusions. The use of stereotaxic cytology enables a marked improvement to be achieved in the diagnostic accuracy of mammography for the identification of suspected NPL to undergo surgical biopsy, notably reducing the cost of biopsy (number of benign lesions for each carcinoma diagnosed) and consequent discomfort for patients.

In this paper we study the development of chick embryo retina cultured in vitro and the effects exerted by insulin. Retinas were removed from 7-day embryos and cultured in serum- and hormone-free medium for 7 additional days. Under these conditions retinal cells survived and underwent cholinergic differentiation, as previously ascertained by Hausman et al. (Dev. Brain Res., 1991, 59: 31-37). However, a great retardation of development was noted compared to uncultured control, 14-day retina. In fact both wet weight and DNA and protein content increased much slower than in ovo and the tubulin content decreased below even the starting value. In addition, although after 7 days in culture retinal cells were organized in identifiable layers, nevertheless the typical organization equivalent to 14-day in ovo retina was absent. The addition of insulin in the medium markedly increased the wet weight of cultured retinas, their protein content and the level of tubulin pools, particularly that of non-assembled fraction. Nevertheless insulin did not modify DNA synthesis and did not induce the increment of both neuron specific enolase and actin. Morphological observations show that insulin markedly increased the number and the thickening of the fiber layers. These results, together with the facts that retina synthesizes and secretes insulin and possesses specific insulin receptors suggest that insulin can have autocrine or paracrine regulatory functions in retinal development by exerting a general effect on retinal growth and a more specific one on tubulin production.

- Abstract
Introduction: Acute compartment syndrome (ACS) is an orthopedic emergency that may lead to devastating sequelae. Diagnosis may be difficult. The aim of this systematic review is to identify clinical and radiological risk factors for ACS occurrence in tibial fractures., Methods: PubMed® database was searched in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Additional articles were found by a manual research of selected references and authors' known articles., Results: The identification process individualized 2758 via database and 30 via other methods. After screening and eligibility assessment, 29 articles were included. Age, gender, occupation, comorbidities, medications, habits, polytrauma, multiple injuries, mechanism, sports, site, open vs closed, contiguous lesion, classification, and pattern were found to be related to ACS occurrence., Conclusions: Younger age and male gender are strong independent risk factors in tibial plateau and shaft fractures. High-energy fractures, polytrauma, more proximal fractures and fractures with contiguous skeletal lesions are aggravating risk factors; higher AO/OTA and Schatzker classification types, increased displacement of the tibia relative to the femur, and increased tibial joint surface width are associated risk factors in tibial plateau fractures; higher AO Foundation/Orthopaedic Trauma Association classification types and subgroups and more proximal fractures within the diaphysis are associated risk factors in tibial shaft fracture. Open fractures do not prevent ACS occurrence. Increased fracture length is the only factor suggesting a higher risk of ACS in tibial pilon fractures. The presence of each independent predictor may have a cumulative effect increasing the risk of ACS occurrence.

- Abstract
Background: Pelvic ring injuries are potentially lethal lesions associated with polytrauma patients and need an efficient trauma team for their management. The purpose of this study was to evaluate the incidence of high-energy blunt pelvic ring injuries and the absolute number of polytrauma patients in a single level I trauma center during the 2020 pseudo-lockdown period related to the Coronavirus pandemic, and to compare it with corresponding periods in 2014-2019 in order to better understand the need of organized and dedicated personnel and infrastructures., Methods: This retrospective cohort study was based on data prospectively recorded into the institutional Severely Injured Patients' Registry. Data were obtained for each year period (January 1st to December 31st) and corresponding pseudo-lockdown period (March 16th to June 19th). High-energy blunt pelvic ring injuries inclusion criteria were: (1) Registry entry between January 1st, 2014 and December 31st, 2020; (2) age ≥ 16 years old; and (3) pelvic ring injury presence. Corresponding exclusion criteria were: (1) death before admission; (2) transfer from another institution > 24 h after trauma; (3) penetrating, blast, burn and electrical injuries, drownings; (4) patients living outside the defined institution's catchment area; and (5) any document attesting the patient's will to not participate in any study. Polytrauma patients inclusion criteria were: (1) Registry entry between January 1st, 2014 and December 31st, 2020; (2) age ≥ 16 years old; and (3) Injury Severity Score ≥ 16. Corresponding exclusion criteria were: (1) death before admission; (2) transfer from another institution > 24 h after trauma; and (3) any document attesting the patient's will to not participate in any study. Categorical variables were reported using proportions and continuous variables using medians and interquartile ranges. Because data were exhaustive for the authors' level I trauma center, no inferential statistics were computed., Results: The incidence of high-energy blunt pelvic ring injuries and the absolute number of polytrauma patients remained within range of previous years despite pseudo-lockdown measures., Conclusions: These observations bring better knowledge about pseudo-lockdown's impact on trauma and may help for future health strategy planning by pointing out the importance of maintaining the activity of level I trauma centers in terms of personnel and infrastructures., (© 2023.

- Abstract
Light is one of the most crucial parameters for enclosed cannabis ( Cannabis sativa ) production, as it highly influences growth, secondary metabolite production, and operational costs. The objective of this study was to investigate and evaluate the impact of six light spectra on C. sativa ('Babbas Erkle Cookies' accession) growth traits and secondary metabolite (cannabinoid and terpene) profiles. The light spectra evaluated included blue (430 nm), red (630 nm), rose (430 + 630 nm, ratio 1:10), purple (430 + 630 nm, ratio 2:1), and amber (595 nm) LED treatments, in addition to a high-pressure sodium (HPS, amber-rich light) treatment as a control. All the LED light treatments had lower fresh mean inflorescence mass than the control (HPS, 133.59 g plant
-1 ), and monochromatic blue light yielded the least fresh inflorescence mass (76.39 g plant-1 ). Measurement of Δ9-tetrahydrocannabinol (THC) concentration (%) and total yield (g plant-1 ) showed how inflorescence mass and THC concentration need to be analyzed conjointly. Blue treatment resulted in the highest THC concentration (10.17% m/m), yet the lowest THC concentration per plant (1.44 g plant-1 ). The highest THC concentration per plant was achieved with HPS (2.54 g plant-1 ). As with THC, blue light increased cannabigerol (CBG) and terpene concentration. Conversely, blue light had a lesser impact on cannabidiol (CBD) biosynthesis in this C. sativa chemotype. As the combined effects of the light spectrum on both growth traits and secondary metabolites have important ramifications for the industry, the inappropriate spectral design could cause a reduction in cannabinoid production (20-40%). These findings show promise in helping producers choose spectral designs that meet specific C. sativa production goals.- Published

- Abstract
The radio-emitting neutron star population encompasses objects with spin periods ranging from milliseconds to tens of seconds. As they age and spin more slowly, their radio emission is expected to cease. We present the discovery of an ultra-long period radio-emitting neutron star, PSR J0901-4046, with spin properties distinct from the known spin and magnetic-decay powered neutron stars. With a spin-period of 75.88 s, a characteristic age of 5.3 Myr, and a narrow pulse duty-cycle, it is uncertain how radio emission is generated and challenges our current understanding of how these systems evolve. The radio emission has unique spectro-temporal properties such as quasi-periodicity and partial nulling that provide important clues to the emission mechanism. Detecting similar sources is observationally challenging, which implies a larger undetected population. Our discovery establishes the existence of ultra-long period neutron stars, suggesting a possible connection to the evolution of highly magnetized neutron stars, ultra-long period magnetars, and fast radio bursts., Competing Interests: Conflict of interest/Competing interests The authors declare no competing interests.

- Abstract
Small-for-size syndrome (SFSS) is a common complication following partial liver transplantation and extended hepatectomy. SFSS is characterized by postoperative liver dysfunction caused by insufficient regenerative capacity and portal hyperperfusion and is more frequent in patients with preexisting liver disease. We explored the effect of the Mesenchymal-epithelial transition factor (MET)-agonistic antibody 71D6 on liver regeneration and functional recovery in a mouse model of SFSS. Male C57/BL6 mice were exposed to repeated carbon tetrachloride injections for 10 weeks and then randomized into 2 arms receiving 3 mg/kg 71D6 or a control immunoglobulin G (IgG). At 2 days after the randomization, the mice were subjected to 70% hepatectomy. Mouse survival was recorded up to 28 days after hepatectomy. Satellite animals were euthanized at different time points to analyze liver regeneration, fibrosis, and inflammation. Serum 71D6 administration significantly decreased mouse mortality consequent to insufficient regeneration of the cirrhotic liver. Analysis of liver specimens in satellite animals revealed that 71D6 promoted powerful activation of the extracellular signal-regulated kinase pathway and accelerated liver regeneration, characterized by increased liver-to-body weight, augmented mitotic index, and higher serum albumin levels. Moreover, 71D6 accelerated the resolution of hepatic fibrosis as measured by picrosirius red, desmin, and α-smooth muscle actin staining, and suppressed liver infiltration by macrophages as measured by CD68 and F4/80 staining. Analysis of gene expression by reverse-transcription polymerase chain reaction confirmed that 71D6 administration suppressed the expression of key profibrotic genes, including platelet-derived growth factor, tissue inhibitor of metalloproteinase 3, and transforming growth factor-β1, and of key proinflammatory genes, including tumor necrosis factor-α, interleukin-1β, chemokine (C-C motif) ligand 3, and chemokine (C-C motif) ligand 5. These results suggest that activating the MET pathway via an hepatocyte growth factor-mimetic antibody may be beneficial in patients with SFSS and possibly other types of acute and chronic liver disorders., (Copyright © 2021 The Authors.

- Abstract
Kidney transplantation (KT) is the best treatment for children in end-stage renal disease. KT has less mortality than dialysis and provides a better quality of life. Thus, the inclusion criteria have been progressively broadened. Histocompatibility and the source of donation are the most relevant factors that influence graft survival. Graft and patient survival have improved dramatically in recent decades, coming close to the results of KT in adults. Some of the specific factors that differentiate it from the adult are: donor-recipient size mismatch,the impact on growth and therapeutic non-compliance. Overall graft survival at 5-years is 90% for living donor KT and 70% for cadaveric donor KT.The most frequent cause of graft loss is chronic rejection.Mortality in the first post-transplant years is less than 6.5%. Infections and cardiovascular complications are the main causes of transplant-related death.Despite the good results, it is imperative to continue investigating how to achieve immunological tolerance. In order to improve the long-term results of the kidney graftis necessary to reduce immunosuppressive treatment and its side effects, such as chronic rejection.

- Abstract
In preclinical studies that involve animal models for hepatic fibrosis, accurate quantification of the fibrosis is of utmost importance. The use of digital image analysis based on deep learning artificial intelligence (AI) algorithms can facilitate accurate evaluation of liver fibrosis in these models. In the present study, we compared the quantitative evaluation of collagen proportionate area in the carbon tetrachloride model of liver fibrosis in the mouse by a newly developed AI algorithm to the semiquantitative assessment of liver fibrosis performed by a board-certified toxicologic pathologist. We found an excellent correlation between the 2 methods of assessment, most evident in the higher magnification (×40) as compared to the lower magnification (×10). These findings strengthen the confidence of using digital tools in the toxicologic pathology field as an adjunct to an expert toxicologic pathologist.

146. Cannabinoids and Terpenes: How Production of Photo-Protectants Can Be Manipulated to Enhance Cannabis sativa L. Phytochemistry.

Desaulniers Brousseau V, Wu BS, MacPherson S, Morello V, and Lefsrud M
- Abstract
Cannabis sativa L. is cultivated for its secondary metabolites, of which the cannabinoids have documented health benefits and growing pharmaceutical potential. Recent legal cannabis production in North America and Europe has been accompanied by an increase in reported findings for optimization of naturally occurring and synthetic cannabinoid production. Of the many environmental cues that can be manipulated during plant growth in controlled environments, cannabis cultivation with different lighting spectra indicates differential production and accumulation of medically important cannabinoids, including Δ
9 -tetrahydrocannabinol (Δ9 -THC), cannabidiol (CBD), and cannabigerol (CBG), as well as terpenes and flavonoids. Ultraviolet (UV) radiation shows potential in stimulating cannabinoid biosynthesis in cannabis trichomes and pre-harvest or post-harvest UV treatment merits further exploration to determine if plant secondary metabolite accumulation could be enhanced in this manner. Visible LED light can augment THC and terpene accumulation, but not CBD. Well-designed experiments with light wavelengths other than blue and red light will provide more insight into light-dependent regulatory and molecular pathways in cannabis. Lighting strategies such as subcanopy lighting and varied light spectra at different developmental stages can lower energy consumption and optimize cannabis PSM production. Although evidence demonstrates that secondary metabolites in cannabis may be modulated by the light spectrum like other plant species, several questions remain for cannabinoid production pathways in this fast-paced and growing industry. In summarizing recent research progress on light spectra and secondary metabolites in cannabis, along with pertinent light responses in model plant species, future research directions are presented., Competing Interests: The authors declare that this study received funding from EXKA Inc.

- Abstract
Osteoarticular infections of the chest wall are relatively uncommon in pediatric patients and affect primarily infants and toddlers. Clinical presentation is often vague and nonspecific. Laboratory findings may be unremarkable in osteoarticular chest wall infections and not suggestive of an osteoarticular infection. Causative microbes are frequently identified if specific nucleic acid amplification assays are carried out. In the young pediatric population, there is evidence that Kingella kingae is 1 of the main the main causative pathogens of osteoarticular infections of the chest wall.

- Abstract
Objective: The optimal duration of postsurgical antibiotic therapy for adult native joint bacterial arthritis remains unknown., Methods: We conducted a prospective, unblinded, randomised, non-inferiority study comparing either 2 or 4 weeks of antibiotic therapy after surgical drainage of native joint bacterial arthritis in adults. Excluded were implant-related infections, episodes without surgical lavage and episodes with a follow-up of less than 2 months., Results: We enrolled 154 cases: 77 in the 4-week arm and 77 in the 2-week arm. Median length of intravenous antibiotic treatment was 1 and 2 days, respectively. The median number of surgical lavages was 1 in both arms. Recurrence of infection was noted in three patients (2%): 1 in the 2-week arm (99% cure rate) and 2 in the 4-week arm (97% cure rate). There was no difference in the number of adverse events or sequelae between the study arms. Of the overall 154 arthritis cases, 99 concerned the hand and wrist, for which an additional subgroup analysis was performed. In this per-protocol subanalysis, we noted three recurrences: one in the 2-week arm (97 % cure); two in the 4-week arm (96 % cure) and witnessed sequelae in 50% in the 2-week arm versus 55% in the 4-week arm, of which five (13%) and six (13%) needed further interventions., Conclusions: After initial surgical lavage for septic arthritis, 2 weeks of targeted antibiotic therapy is not inferior to 4 weeks regarding cure rate, adverse events or sequelae and leads to a significantly shorter hospital stay, at least for hand and wrist arthritis., Trial Registration Number: NCT03615781., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

- Abstract
Introduction: High morbidity has been described in secondary chylothorax. Thoracic duct embolization (TDE) after intranodal lymphangiography (IL) is one of the treatments in adults but there is poor experience in children. We aim to describe our experience with this technique for refractory pediatric chylothorax., Methods: A retrospective study of patients with refractory chylothorax treated with thoracic duct embolization at our Institution in the last 4 years was performed. Lymphatic vessels visualization was obtained by intranodal lymphangiography with ethiodized oil. Demographic and clinical data as well as imaging findings were collected., Results: A total of 4 patients were treated during the study period with a median of age and weight of 2.5 months (1-16) and 4.25 kg (2.8-10) respectively. Chylothorax was secondary to cardiothoracic surgery in 3 patients and to venous thrombosis in the other one. Medical treatment was provided during a median of 47 days (13-56) without benefit in thoracic output [median: 46 ml/kg/day (19-64)]. After IL, thoracic duct catheterization was achieved in one patient however embolization was not possible. Chylothorax stopped in the 3 post-surgical patients regardless of how much lymphatic visualization was achieved in IL. In the venous thrombosis patient surgical treatment was performed 6 days after the study., Conclusion: IL can be a diagnostic and therapeutic tool in children. Ethiodized oil seems to seal lymphatic leak in postsurgical chylothorax. IL could be an option for chylothorax in patients too sick for surgical treatment or in whom thoracic duct embolization is not feasible.
