BACKGROUND |
Combined-modality therapy has become standard for many patients with non-small cell lung cancer. Although surgical resection offers the best chance for long-term survival, the limited number of resectable patients and the presence of occult micrometastatic disease has limited the effectiveness of this modality alone. |
METHODS |
The authors reviewed several trials involving the use of induction chemotherapy in managing resectable non-small cell lung cancer. |
RESULTS |
Extensive phase II experience in patients with stage III disease has confirmed the feasibility of this approach. Unfortunately, heterogeneous patient populations and treatment regimens limit the ability to draw firm conclusions from these trials alone. While the phase III experience has been limited, long-term follow-u... |
CONCLUSIONS |
Results from ongoing randomized trials studying the impact of induction therapy on well-defined patient populations will be necessary before the optimal regimen and patient population can be identified.Improved δ13C method to assess soil organic carbon dynamics on sites affected by soil erosion |
The assessment of soil organic carbon (SOC) loss and input after land‐use change is based largely on comparisons between disturbed sites and an undisturbed reference site. At sites affected by soil erosion this comparison neglects the interactions between soil erosion, decomposition and SOC input. Our aim was to develo... |

OBJECTIVES AND IMPORTANCE: Although controversial, revascularization of the distal posterior cerebral artery (PCA) may become necessary in treating complex PCA aneurysms before proximal parent vessel sacrifice. The revascularization of the distal PCA territories of two patients with peripheral PCA aneurysms is presente... |
CLINICAL PRESENTATIONS |
One patient had an aneurysm of the P2-P3 segment and failed a selective P2 balloon occlusion test by developing homonymous hemianopia before planned parent vessel sacrifice. The other patient with a giant P2 segment aneurysm presented with visual field deficits. |
TECHNIQUE |
The distal segment of PCA was revascularized before the aneurysms were trapped by surgical clipping or coil occlusion of the distal P2 segment, proximal to the aneurysms. In both cases, the occipital artery was used as the "donor" vessel. Temporary occlusion times were 22 and 20 minutes, respectively. Both grafts were ... |
CONCLUSION |
De novo distal P2 sacrifice, advocated for treating peripheral PCA aneurysms, leads to visual field deficits in some patients. Revascularization of the distal segment of the PCA, less technically demanding than bypass to other PCA segments, preserves blood flow, thus sparing vision in this subset of patients.Clinical E... |
A double‐blind evaluation of an intradermal “tumor skin test,” carried out over a three‐year period, involved 470 subjects, the majority of whom were suspected of having malignant disease. The test gave highly positive results in early cancer and it broadly discriminated between subjects with early cancer and those wit... |
In utero exposure to antiepileptic drugs such as carbamazepine can result in several different major malformations, mainly cardiac and facial anomalies. We report prenatal diagnosis of a case with ostium primum type ASD and another case with muscular VSD associated with preconceptional and antenatal exposure to carbama... |

OBJECTIVE |
To explore the mechanism underlying micro ribonucleic acid (miR)-21 in the invasion of rat aortic aneurysm cells in vitro by regulating matrix metalloproteinase (MMP)-2 and MMP-9. |
MATERIALS AND METHODS |
Rats were randomly divided into three groups: control group, model group, and miR-21 group. Real Time fluorescence quantitative Polymerase Chain Reaction (qRT-PCR) was adopted to detect the levels of miR-21 in each group of cells, transwell assay was performed to measure the effect of miR-21 on the invasion of aortic a... |
RESULTS |
The expression level of miR-21 in thoracic aortic aneurysm cells in model group was significantly higher than that in normal group (p<0.05), and that in miR-21 group was remarkably higher than that in model group (p<0.05). MiR-21 group had evidently more aortic aneurysm cells and stronger cell invasion ability than nor... |
CONCLUSIONS |
In aortic aneurysm cells of rats, miR-21 could suppress the expression of PTEN and activate MMP-2 and MMP-9 signals to promote the proliferation and migration of aortic aneurysm cells.Steroids for Crohn's disease--an appreciation and a vote of confidence. |
My dear friend and long-time collaborator, Dr. Daniel H. Present, has been the foremost proponent of the dangers of steroids in the treatment of Crohn’s disease and indeed the ability to successfully manage Crohn’s disease without steroids at all (1). I have never agreed with this stance, but have never written to cont... |
The Proterozoic—Phanerozoic transition recorded a general trend of decrease in phytoplankton cell size, in contrast to the earlier and much larger Ediacaran acritarchs. Particularly minute, unornamented but sculptured organicwalled microfossils have been recovered from the lower Cambrian Lükati Formation in northern Es... |
