CDK9 inhibition induces epigenetic reprogramming revealing strategies to circumvent resistance in lymphoma.

Diffuse large B-cell lymphoma (DLBCL) exhibits significant genetic heterogeneity which contributes to drug resistance, necessitating development of novel therapeutic approaches. Pharmacological inhibitors of cyclin-dependent kinases (CDK) demonstrated pre-clinical activity in DLBCL, however many stalled in clinical development. Here we show that AZD4573, a selective inhibitor of CDK9, restricted growth of DLBCL cells.

Generation of a humanized afucosylated BAFF-R antibody with broad activity against human B-cell malignancies.

B-cell activating factor receptor (BAFF-R) is a mature B-cell survival receptor, which is highly expressed in a wide variety of B-cell malignancies but with minimal expression in immature B cells. These properties make BAFF-R an attractive target for therapy of B-cell lymphomas. We generated a novel humanized anti BAFF-R monoclonal antibody (mAb) with high specificity and potent in vitro and in vivo activity against B-cell lymphomas and leukemias.

Classification of three corynebacterial strains isolated from a small paddock in North Rhine-Westphalia: proposal of sp. nov., sp. nov. and sp. nov.

Three novel corynebacterial species were isolated from soil sampled at a paddock in Vilsendorf, North Rhine-Westphalia, Germany. The strains were coccoid or irregular rod-shaped, catalase-positive and pale white to yellow-orange in colour. By whole genome sequencing and comparison of the 16S rRNA genes as well as the whole genome structure, it was shown that all three strains represent novel species of the family , order , class .

Targeted genome editing in the rare actinomycete Actinoplanes sp. SE50/110 by using the CRISPR/Cas9 System.

The application of genome editing technologies, like CRISPR/Cas9 for industrially relevant microorganisms, is becoming increasingly important. Compared to other methods of genetic engineering the decisive factor is that CRISPR/Cas9 is relatively easy to apply and thus time and effort can be significantly reduced in organisms, which are otherwise genetically difficult to access. Because of its many advantages and opportunities, we adopted the CRISPR/Cas9 technology for Actinoplanes sp.

Preoperative radiation therapy for locally advanced carcinoma of the rectum. Clinicopathologic correlative review.

During a three-year period, 27 patients with the diagnosis of adenocarcinoma of the rectum were referred to the Department of Radiation Oncology and accepted for preoperative radiation therapy. The referral was based solely on endoluminal ultrasound staging (ELUS) of an unfavorable lesion (n = 12) or ultrasound staging with the clinical impression of a fixed (n = 9) or tethered (n = 6) lesion. High-dose (4,500-5,600 cGy) preoperative radiation was followed by definitive surgery in four to seven weeks.

Transrectal ultrasonography in the evaluation of rectal and extrarectal disease.

Transrectal ultrasonography is a technique that is gaining popularity in the assessment of rectal and extrarectal disease. From April 1987 to May 1989, 53 transrectal sonograms were done to evaluate rectal disease. Twenty-seven of 30 adenocarcinomas have been correctly staged.

[Relations between disordered exocrine pancreas function, alcohol consumption and age in alcoholics].

During clinical withdrawal treatment, a disturbed exocrine pancreas function was found in 28 per cent of 72 alcohol addicts, which occurred in connection with an alcohol-induced pancreatitis. The clinical course was mainly quiescent. Altered bicarbonate concentrations and enzyme dissociations were found as a result of the secretin pancreozymin test.

[Alcohol induced damage to the pancreas in patients with increased blood alcohol levels detected in road traffic].

50 patients, driving motor-cars, having increased blood alcohol levels, were registrated and prosecuted. They voluntary underwent catamnestic researches for early diagnosis of alcohol induced lesions of the pancreas. In relation to the habitual drinking systems the study concluded 28 (56 per cent) healthy persons, 13 (26 per cent) alcohol endangered cases, 9 (18 per cent) alcoholics.

[Endangering the water-electrolyte balance in gastrointestinal diseases in the aged].

In old people the range of operation, as well as the adaptability of the electrolyte and water metabolism, is reduced by the involutive reduction of the renal, pulmonary and endocrinic functions, as well as by a reduced feeling of thirst, a reduction of the buffer mechanisms, and a dwindling amount of body water. The threat to the maintenance of the requisite amount of body-water and to a normal electrolysis, caused by gastro-intestinal illnesses, is discussed from the point of view of geriatrics. Hydro-mineral upsets occurring in gastroenterology are primarily caused either by an inadequate supply, inadequate absorption, or by an extra-ordinary loss of intestinal secretions, as well as by interference with the normal electrolyte and water metabolism due to medical treatment.

[Use of anamnestic questionnaires in gastrointestinal diseases in the aged].

The authors relate their experiences in using questionnaires for taking the history of patients with gastroenterological enterological ailments. They have found that the older the patient, the more the results of the questionnaire diverge from those obtained by conventional methods of history-taking. Consequently the authors advise a cautious approach to the use of questionnaires when dealing with elderly patients.

Goiter and deaf mutism.

The occurrence of deaf-mutism and goiter unassocaited with creatinism or mental retardation in euthyroid patients is known as Pendred's Syndrome. It is considered due to a single mutant recessive gene responsible for both the goiter and deafness. The penetrance is high, the intenseness of expressivity may vary within the same family and only one generation is affected.
