Background: The purpose of this study was to compare the clinical results of modified open Bankart & Bristow procedure with union of the transferred coracoid process ( union group), with nonunion ( nonunion group) and open Bankart repair (OB group) for traumatic anterior shoulder instability of collision and contact athletes.
Methods: We studied 48 shoulders in union group, 17 shoulders in nonunion group and 18 shoulders in OB group retrospectively. We evaluated the clinical outcome using recurrence rate, return to sports activities, the JSS Shoulder Instability Score (JSS-SIS) and Rowe score.
Results: As for recurrence after surgeries, no cases (%) in union group, one case (.%) in nonunion group and cases (.2%) in OB group were experienced. Forty three cases (95.6%) in union group, 15 cases (88.2%) in nonunion group and 12 cases (66.7%) in OB group completely returned to their preoperative sports activities on average at ., .7 and 7. months respectively. The JSS-SIS and Rowe score were 95. and 96. points in union group, 91. and 92.3 points in nonunion group and . and 76.7 points in OB group at the time of final investigation. The nonunion group showed similar results to union group these good results were different from OB group results.
Conclusion: It is assumed that stabilizing mechanism of the shoulder for open Bankart & Bristow procedure is not only due to bone block of transferred coracoid process in front of the glenoid neck but also mainly the adhesion of transferred conjoined tendon to subscapularis muscle and the dynamic buttress effect by transferred conjoined tendon across the antero-inferior aspects of the glenohumeral joint.

Aim: T cell-mediated immunity is involved in the pathogenesis of atherosclerosis and arteriosclerosis. This study examined whether the -1 pathway affects the development of arteriosclerosis after vascular injury. Methods and Results: The left or right femoral arteries of adult male mice weighing to 25 g were injured with a straight spring wire. The injured artery was excised 28 days later. Confocal microscopy revealed intense expression of both -1 and -1BBL in the developing neointima and media. Similar results were obtained on immunoblotting analysis of lysates of the injured arteries. We gave mice an injection of 100 μg or 200 μg -1-fused with human immunoglobulin (Ig) every other day over the course of days. As compared with untreated controls (intima/media ratio, 2.13 ± .37, n=10), the intima/media ratio was smaller in mice treated with 200 μg of -1BBIg (1.20 ± .30, n=6, p<.05), but not in mice treated with 100 μg of -1BBIg (1.56 ± .27, n=). Conclusions: -1 inhibits neointimal hyperplasia after vascular injury. Our fi ndings suggest that -1 is involved in injury-induced neointimal hyperplasia and may be an effective target for the treatment of neointimal hyperplasia.

Water soluble organic compounds (WSOC) in airborne particulate matter (PM) have received considerable attention in recent years due to their abundance and their importance in atmospheric processes. The analysis of WSOC is necessary for quantifying the relative contribution of individual organic compounds to the total WSOC mass. In the present work, we evaluated the performance of a microwave-assisted extraction (MAE) method for the determination of WSOC in PM and compared the data with those of a conventional ultrasonic extraction (USE). The experimental results showed that the MAE method requires a shorter extraction time ( min) compared to USE. The isolated water-soluble organic fraction of PM was subsequently analyzed using ion chromatography (IC) for low molecular weight organic acids. The rapid MAE method was used in conjunction with IC for the analysis of organic acids in PM samples, collected from different sources.

The performance of single pitch and multi pitch screw anchors during the application of installation torque is presented. An experimental testing program was conducted using five models of screw anchors with different geometry. The effect of the shape of the screw element, sand properties, and installation depth on the required installation torque value was examined. A theoretical model was developed from which the required installation torque value can be calculated in terms of the influencing factors. The required installation torque can be determined in terms of the ultimate uplift resistance calculated from any of the available theories. Based on the actual installation torque value measured in the field, the anticipated pullout capacity can be back calculated from the present theory. A comparison between theoretical and experimental results showed good agreement. Also, good agreement was observed when the present theoretical results were compared with the available field results reported in the literature.

B. subtilis spores,

. coli -1 and

E

. coli B/r were bombarded with α-particles and heavy ions of carbon, nitrogen and oxygen accelerated in the IPCR Cyclotron. The RBE versus LET_∞ curve for B. subtilis spores showed a maximum peak at ?? 120 keV/μm, while those for

E

. coli -1, and

E

. coli B/r declined without any maximum as LET_∞ values increased. In the region of α-particles, the effective inactivation cross section (S_eff) for these three strains increased with increasing LET_∞ and the rates of increase in S_eff in the LET region from ?? 30 to ?? 150 keV/μm were 15., 1. and 2. times for B. subtilis spores,

E

. coli -1, and

E

. coli B/r, respectively. In the case of B. subtilis spores, S_eff values for heavy ions were almost independent of their energies, but the other two strains showed a considerable dependence upon beam energy. The charcteristic LET dependence of S_eff observed in this study was fairly well explained by the target theory based on microdose concept.

Aim: It has been reported that beta-blockers () reduce cardiovascular events in patients with atherosclerotic disease. However, little is known about the efficacy of these drugs in patients with critical limb ischemia (CLI). We investigated whether beta-blocker therapy affects the clinical outcomes of CLI patients.
Methods: Between March 2004 and December 2011, 1,873 consecutive CLI patients who received endovascular therapy (EVT) (394 -treated patients and 1,479 non--treated patients) for de novo infrainguinal lesions were identified retrospectively. A propensity score analysis was used for risk adjustment in a multivariable analysis and one-to-one matching (: 305, non- 305). The primary endpoint was amputation-free survival (AFS), and the secondary endpoints were overall survival and the rates of limb salvage and freedom from major adverse limb events (MALE; including repeat reintervention, surgical conversion and major amputation). The mean follow-up period was ±15 months.
Results: In the propensity score-matched pair analysis, there were no significant differences in AFS between the patients treated with and without beta-blockers (58.8% vs. 58.% at three years, log-rank p=.76). There were also no significant differences in the limb salvage rate (88.3% vs. 88.8 at three years, log-rank P=.41), overall survival (63.% vs. 62.% at three years, log-rank P=.70) and freedom from MALE (43.6% vs. 44.% at three years, log-rank P=.58) between the patients treated with and without beta-blockers.
Conclusions: The present results suggest that beta-blocker therapy does not worsen the clinical outcomes after EVT in CLI patients.

The design implication of stress-confinement effect of nonwoven geotextile is addressed. The unconfined and confined strengths of a selected needle-punched nonwoven geotextile are used to conduct a comparative design of a granular soil retaining wall based on a limit equilibrium approach. A higher wall may be allowed when considering the confined strength as compared to the unconfined strength. For a selected wall height, confined strength allows for fewer geotextile layers when compared to that designed using unconfined strength. It is recommended that stress-confinement test procedure should be standardized so that confinement effect of some nonwoven geotextiles may be incorporated into an individual wall design procedure.
