PM2.5, due to its small particle size, strong activity, ease of the attachment of toxic substances and long residence time in the atmosphere, has a great impact on human health and daily production. In this work, we have presented patterned nanofiber air filters with high optical transparency, robust mechanical strength and effective PM2.5 capture capability. Here, to fabricate a transparency air filter by a facile electrospinning method, we chose three kinds of patterned wire meshes with micro-structures as negative receiver substrates and directly electrospun polymer fibers onto the supporting meshes. Compared with randomly oriented nanofibers (named “RO NFs” in this paper) and commercially available facemasks, the patterned air filters showed great mechanical properties, and the water contact angles on their surfaces were about 122–143° (the water contact angle for RO NFs was 81°). In addition, the patterned nanofibers exhibited high porosity (>80%), and their mean pore size was about 0.5838–0.8686 μm (the mean pore size of RO NFs was 0.4374 μm). The results indicate that the transparent patterned air filters have the best PM2.5 filtration efficiency of 99.99% at a high transmittance of ∼69% under simulated haze pollution.PM2.5, due to its small particle size, strong activity, ease of the attachment of toxic substances and long residence time in the atmosphere, has a great impact on human health and daily production. 相似文献

Detailed physicochemical and computational investigation are made to explore different aspects of complexation between bovine serum albumin (BSA) and three structurally different surface active ionic liquids (SAILs), 1-dodecyl-3-methylimidazolium chloride, [C12mim][Cl]; 3-(2-(dodecylamino)-2-oxoethyl)-1-methyl-1H-imidazol-3-ium chloride, [C12Amim][Cl] and 3-methyl-1-dodecyloxy carbonyl methylimidazolium chloride, [C12Emim][Cl]. The interfacial and bulk complexation behavior has been monitored using tensiometry, conductivity, steady-state fluorescence and turbidity measurements. Thermodynamic insights about complexation have been obtained using isothermal titration calorimetry (ITC) measurements whereas molecular docking studies were used to predict the possible binding sites of SAILs on BSA. The information obtained from these studies helped in establishing the formed BSA–SAIL complex as a pH dependent colloidal transport system for controlled transport of a lipophilic dye, Rhodamine 6G (R6G), in aqueous phase, which is supported by confocal laser scanning microscopy (CLSM). In the present work, the effect of functionalization over the alkyl chain of SAILs, modulating the colloidal properties of SAIL–BSA systems, has been explored along with the utilization of these complexes as a pH dependent reversible carrier of lipophilic molecules. It is expected that besides providing basic understanding of colloidal complexes of BSA with SAILs, the present work is expected to be helpful in extending the applications of such colloidal systems for material transport.Physicochemical and computational investigation of complexation between BSA and SAILs with application in material transport. 相似文献

Purpose
We investigated the treatment outcomes according to neuropathic bladder sphincter dysfunction (NBSD) type after oral oxybutynin (OBT) treatment in children with NBSD caused by myelodysplasia.Methods
Among 334 pediatric patients who were diagnosed with NBSD caused by myelodysplasia, only children treated with oral OBT for more than 1 year with pre- and post-treatment urodynamic studies and dimercaptosuccinic acid (DMSA) were retrospectively reviewed. We compared pre- and post-treatment urodynamic parameters including maximum cystometric capacity (MCC), MCC/estimated bladder capacity (EBC), and compliance by NBSD type in children. We also compared renal scarring on pre- and post-treatment DMSA by NBSD type in children.Results
Our study population was comprised of 81 children (45 boys and 36 girls), with a mean age of 4.2 ± 3.4 years. The mean follow-up duration was 4.5 (range 1.0–15.1) years. After OBT treatment, MCC was increased significantly in all types of NBSD from 110.3 ± 62.2 to 202.3 ± 103.9 ml (p < 0.05), compliance was significantly improved from 6.4 ± 6.1 to 11.1 ± 9.6 ml/cmH2O (p < 0.05), but MCC/EBC was slightly decreased from 75.2 ± 46.9 to 69.8 ± 33.3 % (p = 0.40). Sub-analyzed by NBSD type, the pre-treatment compliance of children with acontractile detrusor with spastic sphincter (n = 16) was markedly decreased compared with other types of NBSD. Acontractile detrusor with spastic sphincter demonstrated the worst renal deterioration on DMSA.Conclusions
Although increases in MCC/EBC were limited, oral OBT treatment markedly improved MCC and compliance in all NBSD types. Children who had acontractile detrusor with spastic sphincter had a relatively high probability of renal deterioration and required specific attention. 相似文献996.

Background and purpose
To determine landmarks for stent positioning in both ureteral orifices (UOs) and the gender differences in their location in men and women.Patients and methods
The location of the UO and the bladder neck (BN) was measured fluoroscopically by the intravesical distal location of an open-ended catheter marked with radiopaque materials. We compared the location in men (n = 12) and women (n = 12) with a full bladder (hydrostatic pressure of 50 cmH2O) or an empty bladder.Results
The mean distances from BN to UO in men and women were significantly different both in an empty bladder (2.5 ± 0.4 and 2.1 ± 0.3 cm, respectively) and in a full bladder (2.9 ± 1.0 and 2.3 ± 0.6 cm, respectively). The location of UO was changed by bladder filling in women but not in men. In women, most UOs were found superior to the symphysis pubis (SP) in empty bladder (66.6 %). Most of this location was observed at behind the upper boarder of SP in full bladder of women (75 %). The BN of women was located at the lower level in basal state compared to men. Also, the location of BN was markedly changed by bladder fulling in women (p = 0.04) but not in men.Conclusions
Significant gender differences were observed in the location of UO and BN. Clinicians should keep in mind the anatomical differences between men and women during fluoroscopic-guided procedure. 相似文献997.

Background
Although psammoma bodies (PB) are found in up to 50 % of papillary thyroid carcinomas (PTC), their clinicopathological significance remains uncertain. The aim of the present study was to determine the clinicopathological significance of PB and the correlation between PB and ultrasonographic intratumoral calcification in PTC.Methods
The clinicopathological parameters, ultrasonographic calcifications, and the presence of PB were evaluated in 258 surgically resected conventional PTC.Results
Psammoma bodies were found in 141 of 258 PTC (54.7 %). The presence of PB was significantly correlated with tumor multifocality, extrathyroidal extension, and lymph node metastasis (P = 0.009, P = 0.004, and P < 0.001, respectively), but not with the BRAFV600E mutation. Higher incidences of both intratumoral and extratumoral PB were found in overt PTC (>1 cm) than in papillary microcarcinomas (≤1 cm) (P < 0.001 and P = 0.015, respectively). Extratumoral PB were only identified in 48.9 % of 141 PTC with PB, and PTC with extratumoral PB showed higher incidences of tumor multifocality, extrathyroidal extension, and nodal metastasis compared to PTC with intratumoral PB (P = 0.014, P = 0.005 and P = 0.001, respectively). Ultrasonographic intratumoral calcification corresponded to clusters of intratumoral PB (P < 0.001) and was associated with nodal metastasis (P = 0.026).Conclusions
The findings of the present study suggest that the presence of PB may be a useful prognostic indicator of aggressive PTC behaviors. In addition, confirmation of ultrasonographic intratumoral calcification would be a useful decision-making criterion when determining the need for preoperative or intraoperative surveillance of nodal metastasis. 相似文献998.

Background
Incidental findings of gallbladder cancer (GBCA) have dramatically increased as an initial presentation of the disease because of the expansion of laparoscopic cholecystectomy. However, the optimal management of T2 GBCA remains at issue.Methods
We compared our 10-year experience with the consensus surgical strategy for T2 GBCA. Between January 2000 and December 2009, 70 patients at Severance Hospital, Yonsei University Health System, Seoul, Korea, underwent surgical treatment for GBCA stage T2. The medical records of 70 patients with T2 GBCA were retrospectively reviewed.Results
Radical cholecystectomy was performed on only 32 (45.8 %) patients. In patients with T2 GBCA and positive lymph nodes (LN), the overall survival rate between cholecystectomy with LN dissection and radical cholecystectomy did not show a significant difference. Twenty patients experienced recurrence during the follow-up period. Among the 11 patients who underwent cholecystectomy with liver resection, only 2 (18.2 %) patients had an intrahepatic recurrence. Of the 9 patients who underwent cholecystectomy without liver resection, 3 (33.3 %) patients had an intrahepatic recurrence. However, recurrences at the gallbladder bed occurred only in one and two patients, respectively, and were not significantly different between the two groups.Conclusions
There was a large gap between clinical practice and treatment guidelines. Though relatively few patients enrolled in this study experienced recurrence, cholecystectomy and LN dissection without liver resection showed similar survival and recurrence patterns compared with those of radical cholecystectomy. To improve consistency between clinical practice and consensus guidelines, the role of limited resection for T2 lesions needs further evaluation. 相似文献999.
