The iron-responsive Fur/RyhB regulatory cascade modulates the Shigella outer membrane protease IcsP.Actin-based motility is central to the pathogenicity of the intracellular bacterial pathogen Shigella. Two Shigella outer membrane proteins, IcsA and IcsP, are required for efficient actin-based motility in the host cell cytoplasm, and the genes encoding both proteins are carried on the large virulence plasmid. IcsA triggers actin polymerization on the surface of the bacterium, leading to the formation of an actin tail that allows both intra- and intercellular spread. IcsP, an outer membrane pro ...201121859852

comparison of atracurium and d-tubocurarine for prevention of succinylcholine myalgia.we compared the incidence of postoperative myalgia (pom) and fasciculations when atracurium (atr) or d-tubocurarine (dtc) was given prior to succinylcholine (sdc) for tracheal intubation in 44 asa class i or ii outpatient females undergoing laparoscopy. the subjects were assigned to one of three groups: group 1 received 0.025 mg/kg atr; group 2 received 0.05 mg/kg dtc; and group 3 received saline (ns), all in a double-blind manner. thiopental was administered 1 min and 45 sec after pretreatment ...20102955717
antiprotease capacity in acute pancreatitis.serial measurements of circulating antiproteases were carried out on 42 consecutive patients admitted with acute pancreatitis. in the 7 days following admission the serum levels of alpha 1 antitrypsin (alpha 1 at), alpha 1 antichymotrypsin (alpha 1 act) and the trypsin inhibitory capacity (tic) increased by more than 300 per cent. the serum concentration of alpha 2 macroglobulin (alpha 2 m) alone showed a decline which was most profound in those patients with severe acute pancreatitis. initial e ...20103768647

[horizontal laparotomy in biliary tract surgery].for operations on the biliary tract the transverse horizontal incision has the same advantages as the subcostal approach: strong abdominal wall, little influence on ventilation and wide access to the subhepatic region. but in addition, the abdominal wall nerves are preserved as much as possible, post-operative evisceration, it is occurs, can easily be repaired and subsequent surgery can be performed using the same route.20102934697
neuron-specific enolase in the diagnosis of small-cell lung cancer with pleural effusion: a negative report.we measured the concentration of neuron-specific enolase (nse) and carcinoembryonic antigen (cea) in the serum and pleural fluid of 53 patients with pleural effusions, including seven patients with small-cell lung cancer (sclc). high levels (above 12.5 micrograms.l-1) of nse in pleural fluid were observed in five patients with sclc (sensitivity 71%). however, pleural fluid nse levels were also increased in five patients with other types of cancer and in four patients with non-malignant inflammat ...20102853080
transfer of pre-embryos donated and fertilized in vivo to recipients given a steroid replacement therapy.this study describes eleven procedures of non-surgical recovery of preimplantation conceptuses from the uteri of eight fertile donor women and the transfer of the recovered pre-embryos into the uteri of infertile recipients with primary ovarian failure, or with hypothalamic--pituitary failure. conjugated oestrogens and progesterone were administered to recipients as replacement steroids during the first 20 weeks of pregnancy, in order to produce a secretory endometrium allowing nidation and deve ...20102851614

extracellular accumulation of proline, serine and trehalose in the haemolymph of osmoconforming brackish-water mosquitoes.larvae of culex tarsalis, a mosquito, are capable of surviving and developing in dilutions of sea water ranging from 0 mosmol l-1 to 700 mosmol l-1. in waters more dilute than 400 mosmol l-1, the larvae osmoregulate, whereas in those more concentrated than 400 mosmol l-1, the osmotic strength of the haemolymph parallels that of the medium, i.e. the larvae osmoconform. over the full range of external concentrations tested, the larvae regulate the levels of na+, k+, mg2+, ca2+ and cl- in the haemo ...20103108441

the versatility of hydroxyapatite blocks in maxillofacial surgery.there is considerable interest at present in the potential role of calcium hydroxyapatite as a biomaterial for bone augmentation in oral and maxillofacial surgery. most of the published work has been on the particulate form, mainly in alveolar ridge procedures. however, hydroxyapatite is also available as solid or porous blocks. the blocks are more predictable in their use than are the particles, and are adaptable and versatile. this paper reviews the biological behaviour of the material and dis ...20102825758

[the treatment of severe, therapy-resistant depression using infusions of antidepressants].infusion-therapy with antidepressants has been of value in severe as well as therapy resistant depressive states. in addition to doses lower than those used for oral treatment, a more rapid onset of therapeutic effect and a better tolerance, the beneficial effect seems also to depend on the setting in which the treatment takes place. infusion-therapy is a combined pharmacopsychotherapeutic procedure. next to infusion-treatment a pretreatment with neuroleptics is advised either via the oral or pa ...20102922514
