OBJECTIVE To assess data on survival, recurrence and histological factors in positive and negative sentinel lymph nodes in thin melanoma cases. METHODS A systematic review was conducted on observational studies in four databases (Cochrane Library, Medline, Embase and Lilacs). Positive and negative micrometastases in sentinel lymph node biopsy were compared regarding the clinical outcomes - de...
Activation of the opioid receptor results in short-term inhibition of intracellular cAMP levels followed by receptor desensitization and subsequent increase of cAMP above the control level (adenylyl cyclase superactivation). Using adenovirus to deliver pertussis toxin-insensitive mutants of the -subunits of Gi/o that are expressed in neuroblastoma Neuro2A cells (G i2, G i3, and G o), we examine...
BACKGROUND To update a previously published systematic review and meta-analysis on the efficacy and safety of tubeless percutaneous nephrolithotomy (PCNL). METHODS A systematic literature search of EMBASE, PubMed, Web of Science, and the Cochrane Library was performed to confirm relevant studies. The scientific literature was screened in accordance with the predetermined inclusion and exclusi...
BACKGROUND End-stage kidney disease is associated with increased arterial stiffness. Although correction of uremia by kidney transplantation (KTx) could improve arterial stiffness, results from clinical studies are unclear partly due to small sample sizes. METHOD AND RESULTS We conducted a systematic review and meta-analysis of before-after design studies performed in adult KTx patients with ...
Radioligand binding experiments were carried out to identify and characterize nonadrenoceptor [3H]idazoxan binding sites and [3H](1, 2-di-(2-tolyl)guanidine) binding sites in the rat and human stomach. Furthermore, we examined two selected aspects of their potential functional significance. Binding of [3H]idazoxan (Kd = 11.1 nM and 12.4 nM, respectively) and [3H]DTG (Kd = 932 nM and 242 nM, res...
IMPORTANCE Low levels of vitamin D are associated with elevated blood pressure (BP) and future cardiovascular events. Whether vitamin D supplementation reduces BP and which patient characteristics predict a response remain unclear. OBJECTIVE To systematically review whether supplementation with vitamin D or its analogues reduce BP. DATA SOURCES We searched MEDLINE, CINAHL, EMBASE, Cochrane ...
Evidence in vitro and in humans suggest that Mg2+ can alter systemic and renal vascular tone. However, the mechanism of these effects is not known. The role of vasodilator prostaglandin release and Ca2+ flux in Mg2+-induced changes in blood pressure and renal blood flow was studied in 10 normal subjects maintained on a fixed 80-mEq Na+ and K+ diet. Magnesium sulfate infused at 200 mg/hr for 3 h...
In vitro chemotactic responses of infective third-stage larvae (L3) of Brugia pahangi to NaCl, Na2HPO4, KCl, K2HPO4, MgCl2 and CaCl2 were assessed. Compared to deionized water as a control, 200 mm NaCl and 100 mm Na2HPO4 significantly attracted L3 (P < 0.01 and P < 0.01), whereas L3 were likely to avoid 200 mm KCl and 100 mm K2HPO4 (P < 0.05 and P < 0.05). L3 showed no significant tendency to a...
The effect of different irrigation quantities on the growth, marketable yield, crop quality (antioxidant activity, mineral and total phenolic content) and irrigation water use efficiency (IWUE) of spinach grown in a semi-arid region of high altitude (1795 m a.s.l.) was determined. Plants were irrigated with three different irrigation quantities which determined considering 100 (I1), 85 (I2) and...
CASE 1 A 61 year old woman presented with a two day history of pleuritic chest pain and a productive cough. Material obtained by biopsy of an endoscopically visible bronchial tumour showed appearances of small cell undifferentiated carcinoma. Staging procedures suggested that this was confined to the thorax. Haematological and biochemical indices were normal. She commenced treatment with two cy...
