以芝麻油为原料,采用化学气相沉积法合成出多壁碳纳米管(MWCNTs),经功能化改性、切短后用作有机光伏太阳能电池的添加剂。该有机光伏电池以聚3-辛基噻吩为光敏分子,PCBM为激子离化剂。结果表明,添加MWCNTs与功能化且切短的fc-MWCNTs,有机光伏电池的功率转换效率能分别提高22%和40%。由于较高的空穴迁移率,激子离化后,P3OT产生空穴的收集和运输得到提高。功能化和切短的fc-MWCNTs增加了其在P3OT,PCBM中的分散性,进而提高功率转换效率。

AIM: To investig.te the effect of adrenalectomy (ADX) on the epididymidis of Sprag.e-Dawley rats. METHODS: The histolog.cal, biochemical (cholesterol protein, zinc, copper, alkaline and acid phosphatase aryl sulphatase, lactic dehydrog.nase and leucine amino peptidase) and hormonal (FSH, LH and testosterone) chang.s of caput and cauda epididymis in ADX rats were observed. RESULTS: Org.n wet weig.t, histolog.cal studies and morphometric measurements indicated a cellular deg.neration in caput and cauda epididymis of ADX rats. Serum testosterone level was sig.ificantly lower in ADX than in sham-operated rats, while the serum FSH and LH were below the detection limit of 1 mIU/mL. The enzymatic activity was hig.er in ADX than in sham-operated rats. Epididymal zinc level increased whereas copper level decreased in ADX rats compared to the sham-operated. CONCLUSION: Adrenalectomy leads to deg.neration of caput and cauda epididymidis epithelial cells as a result of decreased supply of testosterone.

Protein trafficking.or protein sorting.in eukaryotes is a complicated process and is carried out based on the information contaified in the protein. Many methods reported prediction of the subcellular location of proteins from sequence information. However, most of these prediction methods use a flat structure or parallel architecture to perform prediction. In this work, we introduce ensemble classifiers with features that are extracted directly from full leng.h protein sequences to predict locations in the protein-sorting.pathway hierarchically. Sequence driven features, sequence mapped features and sequence autocorrelation features were tested with ensemble learners and their performances were compared. When evaluated by independent data testing. ensemble based-bag.ing.alg.rithms with sequence feature composition, transition and distribution （CTD） successfully classified two datasets with accuracies g.eater than 90%. We compared our results with similar published methods, and our method equally performed with the others at two levels in the secreted pathway. This study shows that the feature CTD extracted from protein sequences is effective in capturing.biolog.cal features among.compartments in secreted pathways.

Aim: To study the effects of adrenalectomy and hydrocortisone on the ventral prostate of SD rats. Methods: Inadrenalectomised (ADX) and ADX + hydrocortisone (1, 2, or 4 mg. treated rats, the prostatic histolog. and thecholesterol, protein, zinc, and copper levels and the enzymic profile (acid phosphatase, alkaline phosphatase, aryl sul-phatase, lactic dehydrog.nase, and leucine aminopeptidase) in the prostatic tissue were determined; the serum hormon-al profile (testosterone, FSH and LH) was also assayed. Results; Adrenalectomy caused a prog.essive deg.nerationin prostatic structure that was not reversed by hydrocortisone treatment. The serum testosterone were sig.ificantly lowerin ADX than in sham operated rats and lower in ADX + hydrocortisone than in ADX-C rats (P g.er in ADX than in sham op-erated rats and hig.er in ADX + hydrocortisone than in ADX-C rats (Pg.ificantly hig.er in sham operated than in ADX, and hig.er in ADX-C than in ADX + hydrocortisone rats (P g.ificantly lower in sham operated than in ADX, and lower in ADX-C thanin the ADX + hydrocortisone rats (P g.cal and func-tional chang.s of the prostate. Hydrocortisone treatment at the doses employed did not reverse these chang.s. (Asian JAndrol 2001 Dec; 3: 289 - 300)
