Purpose: To evaluate the efficacy and toxicity of hypofractionated stereotactic body radiotherapy in patients with Stage I/II non-small-cell lung cancer.
Methods And Materials: Forty-three patients with inoperable Stage I/II non-small-cell lung cancer underwent treatment prospectively using the stereotactic gamma-ray whole-body therapeutic system (body gamma-knife radiosurgery) with 30 rotary conical-surface Co(60) sources focused on the target volume. Low-speed computed tomography simulation was conducted, which was followed by three-dimensional conformal radiotherapy planning.
Background & Objective: Standard chemotherapy for advanced gastric cancer remains undefined. Phase II trials show that taxol is effective in treating advanced gastric cancer. This multi-center prospective open randomized controlled study was to compare the efficacy of Taxol plus calcium folinate (CF)/5-fluorouracil (5-FU), Taxol plus oxaliplatin (OXA), and CF/5-FU plus cisplatin (DDP) on advanced gastric cancer, and analyze their toxicities.

Methods: Forty-five rats were divided into five groups (each group n = 9). Group C: control group; group G: geranylgeranylacetone (GGA) was administered without heat stress; group S: local heat stress alone; group WG: GGA plus whole-body heat stress; group SG: GGA administration plus local heat stress.

Aim: To describe a new classification method of right hepatectomy according to the different special positions of tumors.
Methods: According to positions, 91 patients with malignant hepatic tumor in the right liver lobe were divided into six groups: tumors in the right posterior lobe and (or) the right caudate lobe compressing the right portal hilum (n = 14, 15.4%), tumors in the right liver lobe compressing the inferior vena cava and (or) hepatic veins (n = 11, 12.

Ergosterol is a principal sterol of fungi. It is a raw material for production of vitamin D2, hydrocortisone, progesterone and brassinolide. Synthesis of ergosterol requires molecular oxygen, and low oxygen tensions was reported to dramatically reduce ergosterol concentration.

Zinc finger transcription factors (TFs(ZF)) were designed and applied to transgene and endogenous gene regulation in stably transformed plants. The target of the TFs(ZF) is the Arabidopsis gene APETALA3 (AP3), which encodes a transcription factor that determines floral organ identity. A zinc finger protein (ZFP) was designed to specifically bind to a region upstream of AP3.

It is overexpressed in mucinous type colorectal cancers but down-regulated in colorectal adenocarcinoma. Phorbol 12-myristate 13-acetate (PMA) treatment of colon cancer cell lines increases MUC2 expression, so we have undertaken a detailed analysis of the effects of PMA on the promoter activity of the 5'-flanking region of the MUC2 gene using stably and transiently transfected promoter reporter vectors.

Method: We treated with linear accelerator radiosurgery 17 patients harboring AVMs in the brain. 15 AVMs were located supratentorially and others infratentorially.
Background: In hyperthermia for cancer therapy, thermal parameters related to tumor response have not yet been clarified. We investigated thermal parameters that could predict tumor response to hyperthermia combined with radiotherapy in locally advanced malignancies.
Methods: Fifty-four patients with locally advanced malignancies who were treated by hyperthermia in combination with radiation therapy were enrolled in this study.
Background: Recently, topical steroid application has been shown by a small number of studies to be an effective alternative to circumcision for the treatment of phimosis. However, only potent or very potent corticosteroids have been more thoroughly studied in this treatment option. A prospective study was conducted to determine whether comparable results could be achieved using a weaker steroid cream.

To determine the effects of chronic nitric oxide (NO) blockade on the pulmonary vasculature, 58-day-old spontaneously hypertensive rats of the stroke-prone substrain (SHRSP) and Wistar-Kyoto rats (WKY) received N(omega)-nitro-L-arginine (L-NNA; 15 mg. kg(-1). day(-1) orally for 8 days).

A 1:1 matched case-control study was conducted to investigate the risk factors for NIDDM in 1995. A total of 100 pairs of case and controls matched on sex, age and hopital of admission. Bivariate analysis revealed 7 factors significantly associated with NIDDM.

In this study, we examined whether endothelin (ET) plays a role in the short-term increase in mean arterial pressure (MAP) after nitric oxide synthase (NOS) inhibition with N(omega)-nitro-L-arginine methyl ester (L-NAME) in stroke-prone spontaneously hypertensive rats (SHRSPs). Experiments were performed by using Inactin-anesthetized male SHRSPs that were pretreated with chlorisondamine to block reflex autonomic cardiovascular effects. Injection of L-NAME (10 mg/kg, i.

This was possible through the use of rapid amplification of cDNA ends-polymerase chain reaction (RACE-PCR) in which the 5' sequence of the human gastric mucin cDNA HGM-1 (1) was used to design the first MUC5AC-specific primer. Primers for subsequent rounds of RACE were designed from the 5'-ends of amplified RACE products.

The human immunodeficiency virus-1 (HIV-1) integrase catalyzes the specific removal of two nucleotides at either 3' end of each long terminal repeat (LTR) sequence of the proviral DNA duplex. The most commonly used in vitro assays for integrase employ 5' end 32P-labeled double-stranded oligonucleotides and the product of integrase-associated endonuclease activity is visualized by denaturing gel electrophoresis followed by autoradiography. We report here a simple assay system based upon the liberation of [35S]GT dinucleotide from the 3' end of a double-stranded U5 LTR sequence derived from HIV-1.

The enteroclysis used for chronic renal failure (CRF) is very effective in the clinical therapy and is developed by professor Zhang Da-ning, a famous specialist in nephrosis in China. In order to find the most effective treatment, we observed 300 patients with CRF who received enteroclysis therapy in the past five years. We focused on the study of the operational method about conservative enteroclysis by multiple cross-transverse comparative method.

Lanreotide is a somatostatin analog which possesses antidiuretic activity in the rat. To determine whether vasopressin participates in the antidiuretic response to lanreotide, experiments were performed with diabetes insipidus (DI) rates homozygous for vasopressin deficiency. Lanreotide significantly increased urine osmolality and decreased urine volume and free water clearance during the 2-h period after injecting 400 microgram/kg s.

SHRSP instrumented with radiotelemetry probes, for continuous monitoring of arterial blood pressure, were given 1% NaCl to drink and Stroke-Prone Rodent Diet and were chronically treated with ifetroban (20 mg/kg/day, n = 10) or vehicle (n = 12) starting at 16.5 weeks of age.

After refractive surgery, corneal haze, ablation zone decentration, ablation zone/pupillary diameter disparity, and under-correction each result in a characteristic pattern on the Night Vision Recording Chart.
Methods: Using the same method, further studies evaluated night vision image degradation in 118 un-operated emmetropic, myopic, hyperopic, and astigmatic eyes and in 26 contact lens wearers.

Background: Removal of donor corneo-scleral shell from a cadaver, leaving the remainder of the eye in place, has become a popular technique. Manual removal can result in excessive trauma to the corneal endothelium or an uneven scleral rim.
Methods: We describe a new technique for corneal retrieval using a sceral suction trephine.
