BACKGROUND Carbonic anhydrase IX (CAIX), a transmembrane glycoprotein, seems to play a key role in the adaption of tumor cells to hypoxia. This study was designed to investigate the clinical role of CAIX and its association with Her-2 in a large cohort of adeno- (AC) and squamous cell carcinomas (SCC) of the esophagus and their metastases. METHODS(More)
BACKGROUND Tumor-associated lymphatic networks are the primary routes for tumor cell dissemination and metastasis. Behind the background of possible lymphangiogenesis-associated therapies, the clinical impact of lymphangiogenesis (measured by lymphatic microvessel density [LMVD]) and specific lymphovascular invasion (LVI) in esophageal cancer remains(More)
The human epidermal growth factor receptor-2 gene (HER-2) encodes for a membrane-bound tyrosine kinase (Her-2), which is overexpressed in various human cancers. Her-2-targeted therapy has recently been shown to be beneficial for patients with advanced gastric cancer. Her-2 protein expression was investigated in 341 esophageal carcinomas [152 squamous cell(More)
The signal-transcriptional factor signal transducer and activator of transcription (STAT3) is overexpressed in various tumor entities and promotes tumor progression and metastasis. The tyrosine-kinase receptor Her-2 was shown to activate STAT3-expression and is overexpressed in a subtype of esophageal cancer (EC). STAT3 also regulates carbonic anhydrase IX(More)
Prevention of heifer mastitis is a key element in preventing mastitis. Since pathogenesis of heifer mastitis is not fully understood yet, combating it is arduous. The goal of this study was to examine whether the premature loss of the keratin plug of the teat canal represents an important risk factor for the development of heifer mastitis. 84 dairy heifers(More)
An account is given in this paper of long-term results obtained from surgical treatment of strain or avulsion fractures of the epicondylus medialis humeri of patients in growth age. Follow-up checks were made on 46 of 59 patients. Anatomic reposition of fragments was clearly superior to percutaneous reposition and fixation of dislocated epicondylus, as(More)
Streptococcus uberis and Staphylococcus aureus are important mastitis pathogens in dairy cows in the entire world. Recent publications showed that an extended therapy can be more efficient in combating such intramammary infections. The objective of this study was to evaluate the effect of an extended intramammary therapy to treat moderate and severe(More)
To estimate disease-free survival it is necessary to allocate patients into tumor risk groups: locally advanced prostate carcinoma with extracapsular spread or localized prostate carcinoma of tumor stage T2c or one of the risk factors PSA >20 or Gleason > or =8 apply for the high-risk group. Intermediate-risk carcinomas are those belonging to tumor stage(More)
The internal teat sealant OrbeSeal® (Zoetis, Berlin, Germany) is intended to prevent new intramammary infection (IMI) throughout the dry period. The aim of this field study was to determine new infection rates in udder quarters applied exclusively with the sealant at dry-off and untreated ones (control group). For that, the new infection rate of udder(More)
This field study focuses on the possible effects of a combination of nonsteroidal anti-inflammatory treatment (carprofen) and a local and parenteral antibiotic on cure rates, survival rate and return to milk production of severe clinical mastitis cases. 69 cows in 3 herds (blocked by parity) with severe clinical mastitis during the first 120 d of lactation(More)
