lack of data on the use of ultrasound contrast medium. AUTHORS' CONCLUSIONS This review provides evidence that TCD or TCCD, administered by professionals with adequate experience and skills, can provide useful diagnostic information for detecting stenosis or occlusion of intracranial vessels in people with acute ischaemic stroke, or guide the request for more invasive vascular neuroimaging, especially where CT or MR-based vascular imaging are not immediately available. More studies are needed to confirm or refute the results of this review in a larger sample of stroke patients, to verify the role of contrast medium and to evaluate the clinical advantage of the use of ultrasound.

No comparable method is available for uncemented implants. Therefore, a hydrogel consisting of hyaluronic and polylactic acids was evaluated in a rabbit model for delivery of antimicrobial agents to prevent post-operative infections. In a pilot study, the suitability of the in vivo model was assessed by testing the hydrogel as carrier material for antimicrobial agents.In the main study, the antimicrobial-agent-loaded hydrogel was evaluated for infection prophylaxis. Rabbits received a titanium rod intramedullary in the tibia after contamination with Staphylococcus aureus. The rods were coated with unloaded hydrogel (Gel), hydrogel loaded with 2 % (Van2) or 5 % vancomycin (Van5), bioactive glass (BAG) or N-acetyl-L-cysteine (NAC). To analyse the infection severity after 28 d, histopathological, bacteriological, micro-computed tomographic and haematological analyses were performed. In the pilot study, the Van5 group had less infection (0/6 infected) as compared to the Gel group (5/5, p = 0.000) and the in vivo model was deemed suitable. In the main study, in the Van2 and Van5 groups, the number of infected animals was lower [1/6 (p = 0.006) and 2/6 (p = 0.044) infected, respectively]. In contrast, BAG and NAC groups showed no infection reduction (5/6 both groups, p = 0.997). The hydrogel can be used as a local carrier of vancomycin for prophylaxis of implant-related infections.The present study showed promising results for local delivery of antibacterial agents by hydrogel to prevent implant-related infections.Fetal growth and development are dependent on placental nutrient transport. The syncytiotrophoblast (ST) and its two polarized plasma membranes, the maternal-facing microvillous membrane (MVM) and fetal-facing basal membrane (BM), represent the primary barrier in the human placenta, controlling transplacental transfer of small solutes. MVM and BM nutrient transporter expression and activity are increased in obese mothers delivering large babies. However, placental nutrient transporter expression and activity in early gestation in normal and obese women are largely unknown. Placentas from normal BMI and obese women at 6-24 weeks of gestation, and term placentas from normal BMI women, were collected and ST plasma membranes isolated. The activity and protein expression of amino acid, glucose, and fatty acid transporters was assessed. No significant differences were observed in placental nutrient transporter protein expression between normal BMI and obese women in early pregnancy. In the MVM, system A amino acid activity (p = 0.02), SNAT2 (p  less then  0.0001), SNAT4 (p  less then  0.001), and GLUT1 (p = 0.01) protein expression were higher at term compared with early gestation. In contrast, MVM system L activity (p = 0.001), FATP4 (p = 0.03), and FATP6 (p = 0.009) protein expression were lower at term compared with early pregnancy. In the BM, there was no change in system L activity across gestation; however, BM FATP6 (p = 0.002) protein expression was lower at term compared with early pregnancy. These results suggest that placental transport of amino acids, glucose, and fatty acids are subjected to coordinated regulation across gestation to meet a fetal nutrient demand that changes with advancing pregnancy.Although physiologic amount of inflammation is necessary for successful implantation, pathological inflammation inhibits the expression of receptivity molecules and genes. selleck Because hydrosalpinges is an inflammatory disease, adverse effects of hydrosalpinges on implantation may be in part mediated by disturbed endometrial expression of nuclear factor-kappa B (NF-κB), a dimer implicated in inflammation. We examined the expression of NF-κB p65 (Rel A) during the window of implantation in the endometrium of infertile women (n = 14) with uni or bilateral hydrosalpinges prior to and following salpingectomy and of fertile controls (n = 14) by immunohistochemistry. We assessed the influence of salpingectomy on NF-κB p65 expression by comparing pre- and post-operative endometrial samples. To evaluate the intensity of endometrial NF-κB p65 (Rel A) immunoreactivity, H-score method was used. We showed a decrease in NF-κB p65 expression in 13 out of the 14 post-salpingectomy endometrial samples. The mean NF-κB p65 level was significantly higher in the endometrium of women with hydrosalpinges before salpingectomy compared with control cases without hydrosalpinges (3.94 ± 6.2 vs 2.18 ± 0.7, p  .64). NF-κB p65 expression was detected in cytoplasmic and membranous parts of luminal and glandular epithelial cells of endometrium obtained before salpingectomy. Both epithelial and stromal components of the endometrium showed decreased staining for NF-κB p65 compared with the pre- and post-salpingectomy samples. The decreased NF-κB p65 (Rel A) immunoreactivity was predominantly localized to luminal and glandular epithelial cells. Uni or bilateral hydrosalpinges causes pathological endometrial inflammation. Improvement in pathological inflammation following salpingectomy in women with hydrosalpinges may be in part mediated by the downregulation of endometrial NF-κB p65 (Rel A) expression.
