<b>Background:</b> The ability to predict poor outcome is important for patient care and treatment decision-making in cases of intracerebral hemorrhage (ICH). Previous studies have included relatively brief follow-up periods small numbers patients, are limited terms considerations regarding individual brain vulnerabilities. <b>Methods:</b> authors prospectively enrolled 1,321 ICH patients nationwide from 33 hospitals. Clinical, laboratory, imaging variables, including white matter lesions...
In order to elucidate the antitumor effect of photodynamic therapy (PDT) using photosensitizing agent hematoporphyrin derivative (Photogem) and a diode laser, we evaluated cell death uterine cancer lines (CaSki, HT3, HeLa, SKOV-3) mice transplanted with TC-1 lung cells. Morphological changes, MTT assay, flow cytometry, cytotoxicity, tumor growth-inhibition study were at various time intervals after PDT. The results showed that survival rates each line decreased dose-response performing Also,...
The depth dependent carrier density was measured on an arsenic implanted silicon sample using scanning capacitance microscopy (SCM). versus voltage scan performed by applying dc biases with a dither ac signal. A strong bias dependence observed at the interface of abrupt junction between n+ and p. SCM images show good agreement quasi-three dimensional simulations, suggesting that they can be used to map device structure.
Ce SAs on porous NGr (1Ce/NGr) show potential for HER with low onset overpotential and high stability. The modified environment of active sites facilitates water adsorption dissociation, liberating hydrogen.
A rapidly absorbed new novel oral dosage form for digoxin termed ‘digoxin dry elixir’ was developed by the spray-drying technique. Digoxin, dextrin and sodium lauryl sulphate were dissolved in a ethanol-water mixture (20:25 w/w) therefore spray-dried to elixir. According scanning electron micrographs, elixir is spherical shape with smooth surface. The geometric mean diameter of determined laser particle size analysis about 13 pm. appearance flow properties almost unchanged 10% ethanol...
The spatial distribution of carriers and an energy level charge traps are measured with a newly built variable-temperature scanning capacitance microscope (VTSCM). system has the resolution ∼20 nm, good enough to measure capture cross section electron or hole traps. By operating VTSCM in isothermal transient mode spectroscopy, trap that lies about 0.40 eV above valence band maximum is identified SiO2/p-Si sample, result compared taken conventional deep spectroscopy.
This study utilized mRNA differential display and the Gene Ontology (GO) analysis to characterize multiple interactions of a number genes involved in human papillomavirus (HPV)-16-induced cervical carcinogenesis. We used HPV-16-positive cancer cell line (SiHa) normal keratinocyte (HaCaT) as control. Each gene has several biological functions GO, hence, we chosen for each gene. then, specific were correlated with expression patterns. The results showed that 157 up- or down-regulated above...

본 연구는 쥐 난자에서 인위적 활성화 처리가 난자의 활성화, cyclin B1 단백질의 발현 및 활성화와 단백질 발현간의 상관관계에 미치는 영향에 관하여 조사하고자 실시하였다. 처리는 7% ethanol(EtOH) or 10μg/ml Ca-ionophore with without cycloheximide (CH) 방법으로 단일 또는 복합처리 하였다. 비율은 단일처리(p<0.05)와 (p<0.01)한 난자가 무처리에 비하여 유의하게 높았다. Cyclin 발현이 EtOH+CH 처리한 난자를 제외한 다른 처리군에서는 감소하였다(p<0.05). 한편 EtOH+CH(r=0.61, p<0.05)와 Ca+CH(r=0.86, p<0.01) 처리그룹에서 발현과 간에 높은 역상관관계가 있음을 확인하였다. 하지만 단일처리 그룹에서는 두 요소간에 상관관계가 없음을 알 수 있었다. 따라서 단일(EtOH and Ca-ionophore) 복합(EtOH+CH Ca+CH) 활성화를 증가시키며, 이것은...
