Cloning and expression of the putative aggregation factor from the marine sponge Geodia cydonium.
2001
Sponges (phylum Porifera) have extensively been used as a model system to study cell-cell interaction on molecular level. Recently, we identified and cloned the putative aggregation receptor (AR) of the sponge Geodia cydonium, which interacts in a heterophilic way with the aggregation factor (AF) complex. In the present study, antibodies against this complex have been raised that abolish the adhesion function of the enriched sponge AF, the AF-Fraction 6B. Using this antibody as a tool, a complete 1.7 kb long cDNA, GEOCYAF, could be isolated from a cDNA library that encodes the putative AF. Its deduced aa sequence in the N-terminal section comprises high similarity to amphiphysin/BIN1 sequen…
Peripheral olfactory function in rats after chemotherapeutic treatment with the anticancer drug docetaxel
2008
International audience; Clinical studies have documented that chemotherapeutic cancer treatment in humans is often associated with weight loss and decreased enjoyment of food. Beside taste, olfaction plays a role in the food intake regulation. We assessed whether hemotherapeutic cancer treatment compromises olfactory function in rats treated with docetaxel (Taxotere, TAX), an antineoplastic drug which disrupts the structures necessary for cell survival and division. Electroolfactogram responses (EOG) can indicate morpho-pathological changes in olfactory epithelium. Male rats received either a single, two or three intravenous injections (one per week) of an estimated 10% lethal dose (LD10) o…
Traditionally used Thai medicinal plants: in vitro anti-inflammatory, anticancer and antioxidant activities.
2009
In order to assess traditional Thai claims about the therapeutic potential of medicinal plants and to select plants for future phytochemical research, nine plant species with anti-inflammatory uses were selected from Thai textbooks and assessed for their in vitro anti-inflammatory, antiproliferative and antioxidant activities.Nuclear factor-kappaB (NF-kappaB) inhibitory effects in stably transfected HeLa cells were determined by luciferase assay, and effects on LPS-induced pro-inflammatory mediators prostaglandin E2 (PGE2), interleukin (IL)-6, IL-1beta, and tumour necrosis factor (TNF)alpha in primary monocytes were assessed by ELISA. Cytotoxic activities were examined against HeLa cells, h…
Nationwide evaluation of day-to-day clinical pharmacists' interventions in German hospitals.
2015
tudy Objective To describe and evaluate the extent and diversity of nationwide data from clinical pharmacists’ interventions (PIs) in German hospitals. Design Retrospective analysis. Data Source The ADKA-DokuPIK German database, a national anonymous self-reported Internet-based documentation system for routine PIs as well as for medication errors reported by German hospital pharmacists. Measurements and Main Results Data sets from ADKA-DokuPIK entered between January 2009 and December 2012 were analyzed descriptively. A total of 27,610 PIs were entered, mainly by ward-based clinical pharmacists (82.5%). Most of the PIs were performed on surgical wards (37.8%), followed by anesthesiology/int…
Hypogonadism in β-thalassemic adolescents: A characteristic pituitary-gonadal impairment. The ineffectiveness of long-term iron chelation therapy
1990
The pituitary-gonadal function was studied in 18 beta-thalassemic female adolescents, 8 with delayed puberty and 10 with primary amenorrhea,treated with repeated transfusions and long-term iron chelation therapy by subcutaneous infusion. A 100 micrograms gonadotropin-releasing hormone (GnRH) test, a double-bolus GnRH test after estradiol administration in non-responders, a 400 micrograms thyrotropin-releasing hormone (TRH) test and a 'high dose' human menopausal gonadotropin (hMG) test were performed. LH and FSH peak levels were significantly lower in thalassemic patients than in controls, both in the 100 micrograms GnRH test (LH was 4.3 +/- 0.7 mIU/ml vs 40.8 +/- 6.0 mIU/ml and FSH 3.3 +/-…
Thiocarbamate-Linked Polysulfonate–Peptide Conjugates As Selective Hepatocyte Growth Factor Receptor Binders
2014
The capacity of many proteins to interact with natural or synthetic polyanions has been exploited for modulating their biological action. However, the polydispersity of these macromolecular polyanions as well as their poor specificity is a severe limitation to their use as drugs. An emerging trend in this field is the synthesis of homogeneous and well-defined polyanion–peptide conjugates, which act as bivalent ligands, with the peptide part bringing the selectivity of the scaffold. Alternately, this strategy can be used for improving the binding of short peptides to polyanion-binding protein targets. This work describes the design and first synthesis of homogeneous polysulfonate–peptide con…
[Pharmacological treatment of depression after acute myocardial infarction].
2005
Depressed mood and other depressive symptoms frequently appear after acute myocardial infarction and it is known how these patients have an increased risk for morbidity and mortality compared to patients without depression. Many risk factors promote the development of clinical depression in patients with recent myocardial infarction. Although a large number of studies underline the negative prognostic impact of depression on the infarcted patient, only rarely depressed patients are appropriately diagnosed and treated. Furthermore it should be borne in mind that the use of psychotropics in medically ill patients requires attention. These compounds, in fact, may interact with the disease caus…
A questionable diagnosis in a woman with drowsiness
2019
A 60-year-old caucasian woman was admitted to our Division of Internal Medicine for a 10-day history of drowsiness, irritability, dysphasia, weakness and difficulties in the maintenance of an upright position with numerous falls, with a traumatic lumbar spine injury and on the left shoulder. Then, while general clinical conditions were getting worse with drowsiness and hyposthenia of the right side of the body, after neurological evaluation, she was recovered in hospital. Pathological history includes a 20-year epilepsy and depression with emotional lability, behavior’s disorders and attempted suicide. For such reason, she was followed in a mental health institute, treated with phenobarbita…
Design, synthesis and biological evaluation of new anticancer drugs: FGFR inhibitors
2021
Fibroblast growth factor receptors (FGFRs) constitute a family of tyrosine kinases receptors (RTKs) that exert pivotal physiological functions in human embryonic and adult tissues. Hyperactivated FGFR signaling drives tumorigenesis in multiple cancer types, including lung and brain cancers. Great effort has been laid on the development of new compounds that specifically target the FGFR axis. However, cancer cell- based and microenvironmental resistance mechanisms against FGFR inhibitors often arise and are currently poorly understood. Furthermore, FGFR-targeted therapy often presents different side effects, e due to the broad biological spectrum of the FGFR signaling axis as well as to its …
