objectives. to investigate the patterns of recurrence associated with superficial inguinal lymphadenectomy (SupIL) and vulvectomy for patients with Stage Ⅰ/Ⅱ vulvar cancer. Met.o.s. A ret.o.pective chart review identified patients from 1990-2001 with Stage Ⅰ/Ⅱ vulvar cancer that underwent SupIL and vulvectomy. Survival was analyzed using the Kaplan-Meier met.o. with Fisher Exact and Chi-square tests for comparisons between groups. Results. 65 patients with Stage Ⅰ/Ⅱ vulvar cancer with a pat.o.ogically negative SupIL were identified (30 Stage Ⅰ, 35 Stage Ⅱ ). three patients recurred in the inguinal region, (4.6% ) and 11 patients (16.9% ) recurred on the vulva. t.o.of the 11 patients died of disease, six patients are alive wit.o.t evidence of disease after addit.o.al therapy. Five-year disease-free survival and overall survival were 66% and 97% , respectively. Risk of recurrence was not associated with smoking status, stage, or margin status. Conclusions. SupIL and vulvectomy for Stage Ⅰ /Ⅱ vulvar cancer have a low recurrence rate in the inguinal region when nodes are negative. the local recurrence rate (17% ) is acceptable, and overall survival is good using this conservative approach.

Highly Defective Dark t.o.(2) Modified with Pt: Effects of Precursor Nature and Preparat.o. Met.o. on Photocatalytic Properties

the study focused on the modificat.o. with platinum of dark defective titania obtained via pulsed laser ablat.o.. Both the met.o. of Pt int.o.uct.o. and the nature of the Pt precursor were varied. All samples exhibited similar phase composit.o.s, specific surface areas, and Pt contents. High-resolut.o. transmission elect.o. microscopy coupled with pulsed Co adsorpt.o. revealed increased dispersity when photoreduct.o. and the hydroxonitrate complex (Me _(4) N) _(2) [Pt _(2) (oH) _(2) (No _(3) ) _(8) ] were used. the sample featured a high content.o. single-atom species and subnano-sized Pt clusters. the X-ray photoelect.o. spect.o.copy results showed that the photoreduct.o. met.o. facilitated the appearance of a larger number of Pt ^(2+) states, which appeared owing to the st.o.g metal-support interact.o. (SMSI) eff ect.o. the transfer of elect.o. density from the elect.o.-saturated defects on the t.o._(2) surface to Pt ^(4+) . In the hydrogen evolut.o. react.o., samples with a significant fract.o. of the Pt ^(2+) ionic component, capable of generating short-lived Pt^(0) single-atom sites under irradiat.o. due to the SMSI eff ect, exhibited the highest photocatalytic activity. the 0.5Pt(C)/t.o.(2) -Ph sample exhibited the highest hydrogen yield with a quantum efficiency of 0.53, retaining its activity even after 8 h of operat.o..

Sensing nanoscale elect.o.agnetic forces when the heat is on

引用

Nat.o.al Science Review 2024年第7期11卷 64-65页

作者： Eric o.Potma Department.o. Chemistry University of California

In scanning probe microscopy(SPM),a sharp tip scans across a sample to produce an image with nanometer-scale resolut.o. or better. SPM contrast is derived from the physical interplay between the tip and the sample. A special class of SPM techniques measures forces when the tip–sample junct.o. is illuminated by an external light source. Photo-induced forces can be sensitive to the optical properties of the sample, thus enabling nanoscale imaging with spect.o.copic,material-specific contrast.

Background. to determine the impact.o. race and other factors on the management and out.o.es of women treated for cervical cancer in a rural state. Met.o.s. Following IRB approval, a ret.o.pective review identified 434 eligible women treated for cervical cancer from 1994 to 2000. Collected data included: demographics, clinicopat.o.ogic data, primary and adjuvant therapy, recurrence, and survival. Statistical analyses were performed with the Chi-square test, Kaplan-Meier met.o., and Cox regression. Results. 304 (70%) of the women were white and 130 (30%) were non-white. Non-whites were more likely to present with advanced stage disease Stage IIB-IVB (25%vs 13%; P tes were more likely to smoke, be married, be employed, and have private insurance. Non whites were more likely to have medical co-morbidities such as diabetes and hypertension. Alt.o.gh whites with early stage disease were more likely to undergo surgery as their primary therapy than non-whites (93%vs 84%; P out.o.es for advanced stage disease were similar between groups. Conclusions. Non-whites diagnosed with cervical cancer are more likely to present with advanced stage disease than whites; however, overall survival was similar between groups. Non-whites with early stage disease were more likely to receive primary radiat.o. therapy than whites. the decision to use radiat.o. therapy vs surgery does not appear to have a detrimental effect.o. overall survival, but may impact quality of life.
