  abstract  = {The clinical and preclinical research of ischemic strokes (IS) is becoming increasingly comprehensive, especially with the emerging evidence of complex thrombotic and inflammatory interactions. Within these, the blood brain barrier (BBB) plays an important role in regulating the cellular interactions at the vascular interface and is therefore the object of many IS-related questions. Consequently, valid, economic and responsible methods to define BBB integrity are necessary. Therefore, we compared the three ex-vivo setups albumin Western blot (WB), IgG WB and albumin intensity measurement (AIM) with regard to validity as well as temporal and economic efficacy. While the informative value of the three methods correlated significantly, the efficacy of the IgG WB dominated.},

  abstract  = {The aim of the present study was a refined analysis of neuroinflammation including TMEM119 as a useful microglia-specific marker in forensic assessments of traumatic causes of death, e.g., traumatic brain injury (TBI). Human brain tissue samples were obtained from autopsies and divided into cases with lethal TBI (n = 25) and subdivided into three groups according to their trauma survival time and compared with an age-, gender-, and postmortem interval-matched cohort of sudden cardiovascular fatalities as controls (n = 23). Brain tissue samples next to cortex contusions and surrounding white matter as well as samples of the ipsilateral uninjured brain stem and cerebellum were collected and stained immunohistochemically with antibodies against TMEM119, CD206, and CCR2. We could document the highest number of TMEM119-positive cells in acute TBI death with highly significant differences to the control numbers. CCR2-positive monocytes showed a significantly higher cell count in the cortex samples of TBI cases than in the controls with an increasing number of immunopositive cells over time. The number of CD206-positive M2 microglial cells increased survival time-dependent. After 3 days of survival, the cell number increased significantly in all four regions investigated compared with controls. In sum, we validate a specific and robustly expressed as well as fast reacting microglia marker, TMEM119, which distinguishes microglia from resident and infiltrating macrophages and thus offers a great potential for the estimation of the minimum survival time after TBI.},

  abstract  = {Background Overexpression of transketolase-like 1 protein TKTL1 in cancer cells has been reported to correlate with enhanced glycolysis and lactic acid production. Furthermore, enhanced TKTL1 expression was put into context with resistance to chemotherapy and ionizing radiation. Here, a panel of human malign and benign cells, which cover a broad range of chemotherapy and radiation resistance as well as reliance on glucose metabolism, was analyzed in vitro for TKTL1 expression. Methods 17 malign and three benign cell lines were characterized according to their expression of TKTL1 on the protein level with three commercially available anti-TKTL1 antibodies utilizing immunohistochemistry and Western blot, as well as on mRNA level with three published primer pairs for RT-qPCR. Furthermore, sensitivities to paclitaxel, cisplatin and ionizing radiation were assessed in cell survival assays. Glucose consumption and lactate production were quantified as surrogates for the "Warburg effect". Results Considerable amounts of tktl1 mRNA and TKTL1 protein were detected only upon stable transfection of the human embryonic kidney cell line HEK293 with an expression plasmid for human TKTL1. Beyond that, weak expression of endogenous tktl1 mRNA was measured in the cell lines JAR and U251. Western blot analysis of JAR and U251 cells did not detect TKTL1 at the expected size of 65 kDa with all three antibodies specific for TKTL1 protein and immunohistochemical staining was observed with antibody JFC12T10 only. All other cell lines tested here revealed expression of tktl1 mRNA below detection limits and were negative for TKTL1 protein. However, in all cell lines including TKTL1-negative HEK293-control cells, antibody JFC12T10 detected multiple proteins with different molecular weights. Importantly, JAR and U251 did neither demonstrate an outstanding production of lactic acid nor increased resistance against chemotherapeutics or to ionizing radiation, respectively. Conclusion Using RT-qPCR and three different antibodies we observed only exceptional occurrence of TKTL1 in a panel of malignant human cell lines in vitro. The presence of TKTL1 was unrelated to either the rate of glucose consumption/lactic acid production or resistance against chemo- and radiotherapy.},

  abstract  = {The neuropeptide pigment-dispersing factor (PDF) plays a prominent role in the circadian clock of many insects including honey bees. In the honey bee brain, PDF is expressed in about 15 clock neurons per hemisphere that lie between the central brain and the optic lobes. As in other insects, the bee PDF neurons form wide arborizations in the brain, but certain differences are evident. For example, they arborize only sparsely in the accessory medulla (AME), which serves as important communication center of the circadian clock in cockroaches and flies. Furthermore, all bee PDF neurons cluster together, which makes it impossible to distinguish individual projections. Here, we investigated the developing bee PDF network and found that the first three PDF neurons arise in the third larval instar and form a dense network of varicose fibers at the base of the developing medulla that strongly resembles the AME of hemimetabolous insects. In addition, they send faint fibers toward the lateral superior protocerebrum. In last larval instar, PDF cells with larger somata appear and send fibers toward the distal medulla and the medial protocerebrum. In the dorsal part of the medulla serpentine layer, a small PDF knot evolves from which PDF fibers extend ventrally. This knot disappears during metamorphosis and the varicose arborizations in the putative AME become fainter. Instead, a new strongly stained PDF fiber hub appears in front of the lobula. Simultaneously, the number of PDF neurons increases and the PDF neuronal network in the brain gets continuously more complex.},

  abstract  = {Die diffusen großzelligen B-Zell-Lymphome (DLBCL) stellen den h{\"a}ufigsten Typ aller Non-Hodgkin-Lymphome dar, sind aber morphologisch, immunologisch, genetisch und klinisch eine sehr heterogene Gruppe. Aufgrund dieser Heterogenit{\"a}t von DLBCL wurde in mehreren Studien untersucht, ob eine molekulare Heterogenit{\"a}t der Tumoren vorl{\"a}ge, bzw. versucht, eine molekulare Reklassifikation zu erreichen. Resultat dieser Bem{\"u}hungen war eine Unterscheidung bzw. Definition einer Keimzentrums- {\"a}hnlichen (GCB-cell-like) Gruppe und einer aktivierten B-Zellen-{\"a}hnlichen (ABC-like) Gruppe, die sich in ihrem Ansprechen auf {\"u}bliche Therapieschemata, mit einer deutlich besseren Prognose f{\"u}r die GCB-like-Gruppe, unterschieden. Die hierbei angewendete Microarray-Technologie hat den entscheidenden Nachteil, dass hierf{\"u}r qualitativ hochwertige RNA zur Verf{\"u}gung stehen muss. Neu ist der Ansatz, unterschiedliche Proteinexpressionsmuster am Paraffinmaterial zur Unterscheidung prognostisch relevanter Gruppen heranzuziehen. Die hierbei erzielten Daten sind allerdings in Ihren Aussagen hinsichtlich der prognostischen Wertigkeiten widerspr{\"u}chlich. In der vorliegenden Arbeit wurden zun{\"a}chst verschiedene biologische Parameter am Paraffinmaterial hinsichtlich ihrer prognostischen Wertigkeit in der Risikostratifikation von DLBCL untersucht. In einem ersten Schritt wurden klinische Daten von 99 de novo entstandenen großzelligen B-Zell-Lymphomen erhoben, bei denen es sich um 84 DLBCL und um elf DLBCL mit einer weiteren Komponente eines follikul{\"a}ren Lymphoms Grad 3B bzw. auch um vier F{\"a}lle mit ausschließlich follikul{\"a}rem Wachstumsmuster handelte. Die Klassifikation der F{\"a}lle nach dem Internationalen Prognostischen Index (IPI) sowie der einzelnen klinischen Parameter des IPI zeigte eine deutliche prognostische Relevanz. In einem zweiten Schritt wurden immunhistochemische F{\"a}rbungen mit verschiedenen Antik{\"o}rpern durchgef{\"u}hrt und auf ihre prognostische Bedeutung {\"u}berpr{\"u}ft. Als negative prognostische Parameter erwiesen sich die Negativit{\"a}t f{\"u}r CD10 sowie BCL-6, also Antigene, die mit einer Keimzentrumszell-Differenzierung assoziiert werden, sowie eine {\"U}berexpression von MUM-1, das mit einer postfollikul{\"a}ren Differenzierung assoziiert wird. Weiterhin konnte gezeigt werden, dass einer Expression von BCL-2 und einem Ki67-Index von unter 80 \% eine negative prognostische Bedeutung zukommt. Die Stratifikation der F{\"a}lle in einen GCB- und einen ABC- Typ anhand des Hans-Klassifikators zeigte nur eine schwache Korrelation zur {\"U}berlebenswahrscheinlichkeit. In einem dritten Schritt wurde gezeigt, dass die kombinierte Analyse jeweils zweier Parameter eine relative Abh{\"a}ngigkeit ihrer Expression von der Expression weiterer Marker erkennen ließ. Aus diesem Grunde wurde ein Modell einer sequentiellen Addition negativer prognostischer Indikatoren entwickelt, in der bei Anwesenheit einer negativen Variable (CD10-Negativit{\"a}t, BCL-6 < 20\%, BCL-2 positiv, MUM-1\&\#8805; 50\% und Ki67 < 80\%) ein negativer Faktor gewertet und die Summe dieser als Risiko-Score angegeben wurde. Die Stratifikation der Patienten anhand dieses „kombinierten immunhistochemischen Risiko-Scores" zeigte drei prognostisch deutlich unterschiedliche Gruppen: In der Gruppe von Patienten ohne Risikofaktoren verstarb lediglich eine Patientin (die eine Behandlung abgelehnt hatte); in der Hochrisikogruppe (Score 5) verstarben alle Patienten innerhalb eines Jahres. Die multivariate Analyse des Scores ergab dabei eine Unabh{\"a}ngigkeit von den Parametern des IPI. In der intermedi{\"a}ren Gruppe mit einem Risiko-Score von 1-4 zeigten sich der IPI sowie eine LDH-Erh{\"o}hung und das Vorhandensein einer B-Symptomatik als geeignete Parameter, um hier eine weitere Stratifizierung durchzuf{\"u}hren. Die vorliegende Arbeit stellt somit eine Erweiterung der publizierten Ans{\"a}tze einer Erfassung prognostischer Indikatoren in kombinierten Algorithmen dar. Eine Verifizierung der gezeigten Ergebnisse in einer homogen behandelten Patientengruppe innerhalb einer klinischen Studie muss Ziel weiterer Untersuchungen sein.},

  abstract  = {Blue nevus is a benign melanocytic lesion, typically asymptomatic and of unknown etiology. Several histologic and clinical variants have been distinguished, the most frequent being common blue nevus, cellular blue nevus, and combined blue nevus. Although melanocytic nevi with a satellite lesion are usually suggestive of locally advanced malignant melanoma, very few cases of blue nevi with satellite lesions have been reported. The diagnosis of common or cellular blue nevi is generally straightforward; however, the presence of structures such as irregular edges or satellitosis are highly suggestive for malignancy, and differential diagnoses such as locally advanced malignant melanoma and malignant blue nevus should be considered. Recurrent blue nevi can display atypical features not seen in the primary lesion, such as pleomorphism and mitotic activity. They usually tend to follow a benign course; however, in some cases, recurrence may indicate malignant transformation. We here report the unique case of a 64-year-old woman with a recurrent cellular blue nevus accompanied by satellite lesions. Such a biological behavior resulting in a clinical presentation as a melanoma-like lesion is a rarity in blue nevus and has not been described before.},

We could document the lowest density of TMEM119-positive cells in MOR deaths with highly significant differences to the control densities in all three regions investigated. In ETH and METH deaths, the expression of TMEM119 was comparable to cell densities in controls.

  abstract  = {Background: Rhabdoid melanoma is a rare variant of malignant melanoma with characteristic cytomorphologic features. Due to the potential loss of conventional melanocytic markers, histopathologic diagnosis is often challenging. We hypothesize that immunostaining for PReferentially expressed Antigen in MElanoma (PRAME) might have the potential to uncover the melanocytic origin of these dedifferentiated tumors. Methods: Four cases of rhabdoid primary melanomas were assessed by immunohistochemistry for expression of PRAME and conventional melanocytic markers. Immunohistochemical expression patterns were analyzed in the rhabdoid primaries and, if available, associated metastases. Results: All four cases of rhabdoid primary melanomas showed a strong nuclear positivity for PRAME, while the expression of conventional melanocytic markers S100, MART-1, SOX-10 and HMB-45 was variable between the analyzed cases. Conclusions: In summary, we report four cases of rhabdoid primary melanoma with high to intermediate expression of PRAME despite the partial and variable loss of other melanocytic markers. Hence, PRAME might facilitate the recognition of this highly aggressive entity to avoid misdiagnosis due to histopathologic pitfalls.},

  abstract  = {Background: Treatment of patients with stage pT1 urothelial bladder cancer (UBC) continues to be a challenge due to its unpredictable clinical course. Reliable molecular markers that help to determine appropriate individual treatment are still lacking. Loss of aquaporin (AQP) 3 protein expression has previously been shown in muscle-invasive UBC. The aim of the present study was to investigate the prognostic value of AQP3 protein expression with regard to the prognosis of stage pT1 UBC. Method: AQP 3 protein expression was investigated by immunohistochemistry in specimens of 87 stage T1 UBC patients, who were diagnosed by transurethral resection of the bladder (TURB) and subsequent second resection at a high-volume urological centre between 2002 and 2009. Patients underwent adjuvant instillation therapy with Bacillus Calmette-Guerin (BCG). Loss of AQP3 protein expression was defined as complete absence of the protein within the whole tumour. Expression status was correlated retrospectively with clinicopathological and follow-up data (median: 31 months). Multivariate Cox regression analysis was used to assess the value of AQP3 tumour expression with regard to recurrence-free (RFS), progression-free (PFS) and cancer-specific survival (CSS). RFS, PFS and CSS were calculated by Kaplan-Meier analysis and Log rank test. Results: 59\% of patients were shown to exhibit AQP3-positive tumours, whereas 41\% of tumours did not express the marker. Loss of AQP3 protein expression was associated with a statistically significantly worse PFS (20\% vs. 72\%, p=0.020). This finding was confirmed by multivariate Cox regression analysis (HR 7.58, CI 1.29 - 44.68; p=0.025). Conclusions: Loss of AQP3 protein expression in pT1 UBC appears to play a key role in disease progression and is associated with worse PFS. Considering its potential prognostic value, assessment of AQP3 protein expression could be used to help stratify the behavior of patients with pT1 UBC.},
