Cytogenetic studies in non-African Burkitt lymphoma

A particular translocation between chromosomes 8 and 14 has been found repeatedly in cytogenetic studies of Burkitt lymphoma, both of African and non-African origin. We report here our findings in cytogenetic studies of direct tumor preparations from 18 non-African Burkitt lymphoma patients, 9 of whom also had cell lines available for study. A t(8;14) was found in direct tumor material in 10 of the 18 patients. Seven of the 9 cell lines had a t(8;14). A total of 15 patients had either a t(8;14) or a 14q+ present in tumor material and/or cell lines. In addition, 8 patients had a peculiar marker chromosome 1. The t(8;14) was not found in every malignant cell and, where present, it was rarely the sole karyotypic abnormality. The relationship of the t(8;14) to the evolution of the tumor is discussed.

Isola spinal instrumentation system for idiopathic scoliosis

Since the definition of three-dimensional components of the scoliotic deformity, there have been important improvements in the surgical treatment of the problem. A derotation maneuver was proposed as a treatment option with CD instrumentation, but the reports of imbalance and decompensation with this system repopularized sublaminar wiring and translation as a corrective maneuver. Isola spinal instrumentation is one of the modern systems that utilizes vertebral translation instead of rod rotation. This study analyzes the results of 24 patients with idiopathic scoliosis who had been followed up for at least 2 years, and were surgically treated with titanium Isola Spinal Instrumentation in the Department of Orthopaedics and Traumatology, Ankara Social Security Hospital. Patients were grouped according to the King-Moe classification. Patients with type III, IV or V curves received only posterior instrumentation while this procedure followed anterior release and discectomy in the same session in patients with type I or II curves. A translation maneuver was utilized in the correction of scoliotic curves using the cantilever technique, either alone or supplemented by sublaminar wiring with Songer multifilament titanium cables. This study aimed to elucidate the effects of this technique in the frontal and sagittal plane curves and the trunk balance. The balance was analyzed clinically and radiologically by measurement of the lateral trunk shift (LT), shift of stable vertebra (SS), and shift of head (SH) in vertebral units (VU). The postoperative correction was significant in the frontal plane for all types of curves (p < 0.05). The postoperative correction was 80.9% +/- 9.5% in type III curves. Overall, the mean Cobb angle of the major curve value in the frontal plane was 66.9 degrees +/- 18.8 degrees, and it was corrected by 62.8% +/- 20.1%. The correction loss of Cobb angles in the frontal plane was 5.4 degrees +/- 5.5 degrees at the last follow-up visit. A normal physiologic thoracic contour (30 degrees - 50 degrees) was achieved in 83.3% of the patients and normal lumbar contour (40 degrees - 60 degrees) in 66.7% of the patients in the sagittal plane. The correction was found to be significant in all balance values (p < 0.05). The postoperative correction in LT values correlated with the correction of the Cobb angle values in the frontal plane. All patients had complete balance (SH: 0 VU and SS: 0 VU) or balanced curves (0 VU < SH, SS < 0.5 VU).Finally, the study concluded that the translation maneuver, especially when used with the cantilever technique, resulted in high correction rates in the frontal plane. Additionally, the technique was also successful in obtaining normal sagittal contours and correcting balance values.     

ConA诱导肝细胞损伤机理及CsA对其损伤的影响

目的　探讨NO、脂质过氧化反应及蛋白巯基状态改变在ConA诱导肝组织细胞损伤过程中的作用以及CsA对其损伤的影响。方法 :尾静脉注射ConA( 2 0mg·kg-1)于雄性BALB/c小鼠作为试验组 ;提前半小时予以CsA( 2 5mg·kg-1)后再按试验组处理作为CsA组。观察血清中ALT、AST、NO-2 及肝组织MDA、TSH、PSH含量在 3h、6h、9h和 12h的动态变化。结果　试验组血清中ALT、AST进行性升高 ,在 12h时与对照组、CsA组比较均P <0 .0 1。试验组动物体内有大量的NO合成 ,血清中NO-2 随时间呈明显上升趋势 ,在 12h时与对照组、CsA组比较均P <0 .0 1。试验组动物肝组织MDA含量逐步升高 ,在 12h与对照组、CsA组比较P <0 .0 1。试验组动物肝组织TSH含量不断下降在 12h与对照组、CsA组比较P <0 .0 5 ;PSH含量亦不断下降在 12h与对照组、CsA组比较P <0 .0 1。对照组和CsA组血清中ALT、AST及NO-2 前后变化不大 ,肝组织MDA、TSH、PSH含量变化亦不明显。结论　在ConA所致肝损伤中 ,动物体内NO生物合成机制被激活 ,是肝细胞损伤的重要介质之一。同时脂质过氧化的发生以及蛋白巯基持续消耗致肝组织细胞的抗氧化能力和解毒能力下降也均是ConA性肝损伤机制之一。免疫抑制剂CsA预处理能阻断ConA性肝损伤的发生 ,免疫介导机制亦可能是其损伤     

In-feed antibiotic effects on the swine intestinal microbiome

Antibiotics have been administered to agricultural animals for disease treatment, disease prevention, and growth promotion for over 50 y. The impact of such antibiotic use on the treatment of human diseases is hotly debated. We raised pigs in a highly controlled environment, with one portion of the littermates receiving a diet containing performance-enhancing antibiotics [chlortetracycline, sulfamethazine, and penicillin (known as ASP250)] and the other portion receiving the same diet but without the antibiotics. We used phylogenetic, metagenomic, and quantitative PCR-based approaches to address the impact of antibiotics on the swine gut microbiota. Bacterial phylotypes shifted after 14 d of antibiotic treatment, with the medicated pigs showing an increase in Proteobacteria (1-11%) compared with nonmedicated pigs at the same time point. This shift was driven by an increase in Escherichia coli populations. Analysis of the metagenomes showed that microbial functional genes relating to energy production and conversion were increased in the antibiotic-fed pigs. The results also indicate that antibiotic resistance genes increased in abundance and diversity in the medicated swine microbiome despite a high background of resistance genes in nonmedicated swine. Some enriched genes, such as aminoglycoside O-phosphotransferases, confer resistance to antibiotics that were not administered in this study, demonstrating the potential for indirect selection of resistance to classes of antibiotics not fed. The collateral effects of feeding subtherapeutic doses of antibiotics to agricultural animals are apparent and must be considered in cost-benefit analyses.
