Decompression Surgery Options for Metastatic Cervical Spine Lesions.

: Metastatic spinal lesions occur in 70% of patients with incurable cancer, and the most common site for bone metastases is the spine. Over the last decade, medical science has made significant progress in treating tumor damage to the spine. The study examined the efficacy of decompression surgery for patients with metastatic cervical spine lesions contributing to spinal cord compression.

Portable ozone sterilization device with mechanical and ultrasonic cleaning units for dentistry.

A portable device for cleaning and ozone sterilization of small-sized delicate dental instruments that cannot withstand the high heat and humidity of standard autoclaving has been developed. The device contains a remote unit for magnetic mechanical washing, an ultrasonic bath for pre-cleaning treatment, and a container for ozone sterilization with a reactor based on dielectric barrier discharge. The maximum ozone concentration in water reached 8.

How African American English-Speaking First Graders Segment and Rhyme Words and Nonwords With Final Consonant Clusters.

Purpose: This study explored how typically developing 1st grade African American English (AAE) speakers differ from mainstream American English (MAE) speakers in the completion of 2 common phonological awareness tasks (rhyming and phoneme segmentation) when the stimulus items were consonant-vowel-consonant-consonant (CVCC) words and nonwords.

Method: Forty-nine 1st graders met criteria for 2 dialect groups: AAE and MAE. Three conditions were tested in each rhyme and segmentation task: Real Words No Model, Real Words With a Model, and Nonwords With a Model.

Metalinguistics, stress accuracy, and word reading: does dialect matter?

Purpose: The authors examined the influence of demographic variables on nonmainstream American English (NMAE) use; the differences between NMAE speakers and mainstream American English (MAE) speakers on measures of metalinguistics, single-word reading, and a new measure of morphophonology; and the differences between the 2 groups in the relationships among the measures.

Method: Participants were typically developing 3rd graders from Memphis, TN, including 21 MAE and 21 NMAE speakers. Children received a battery of tests measuring phonological and morphological awareness (PA and MA), morphophonology (i.

Third graders' metalinguistic skills, reading skills, and stress production in derived English words.

Purpose: This study examined relationships between 3rd graders' metalinguistic skills (phonological and morphological awareness), reading skills (decoding and word identification), and accurate stress production in derived words with stress-changing suffixes.

Method: Seventy-six typically developing 3rd-grade children (M=8;8[years;months]) participated in a battery of tests measuring general oral language ability, phonological and morphological awareness skills, reading skills, and derived word production.

Results: Significant positive correlations between stress accuracy in derived words and all other measures were found.

Exploration of lexical-semantic factors affecting stress production in derived words.

Purpose: This study examined whether lexical frequency, semantic knowledge, or sentence context affect children's production of primary stress in derived words with stress-changing suffixes (e.g., -ity).

[Specialized epidemic brigade during extreme situation].

Information on the main trends in the activity and on the organization of the work of the specialized antiepidemic brigade of the Stavropol Research Institute for Plague Control in Grozny in the first half of the year 2000 is presented. At the initial stage of this activity the specialists of the brigade were entrusted with all functions of the local state sanitary and epidemiological service which had lost its qualified personnel and material resources. At the initial stages of the work the main attention was drawn to the organization of the registration of patients with infectious diseases, to the control of drinking water and to the realization of immunoprophylactic measures, etc.

[Outbreak of typhoid fever in the Chechen Republic in 2000: epidemiological characterization].

The results of the epidemiological investigation of the outbreak of typhoid fever in Achkhoi-Martan region are presented. During the period from December 1999 to April 2000 the disease was diagnosed in 43 persons. The cases of the disease were registered in 3 settlements: Lermontov-Yurt, Kulary and Sernovodsk.

Nocardiopsis tropica sp. nov., Nocardiopsis trehalosi sp. nov., nom. rev. and Nocardiopsis dassonvillei subsp. albirubida subsp. nov., comb. nov.

Sixteen strains isolated from different soils and marine sediments and 'Nocardiopsis trehalosi' VKM Ac-942T were subjected to taxonomic analyses. The morphological and chemotaxonomic characteristics of the strains matched those described for members of the Nocardiopsis. Based on 16S rDNA sequence analysis, DNA-DNA hybridization values and phenotypic characteristics, including the composition of menaquinones and cell wall teichoic acids, two new species are proposed, Nocardiopsis tropica sp.

Teichoic acids of the cell wall of Nocardiopsis listeri, Nocardiopsis lucentensis, and Nocardiopsis tregalosei.

The structures of teichoic acids of three Nocardiopsis species were established. The cell wall of Nocardiopsis listeri VKM Ac-1881T contains two teichoic acids (TA). TA1 is 1,3-poly(glycerol phosphate) with 50% glycerol phosphate residues substituted by alpha-N-acetylglucosamine in the C-2 position.

Novel cell-wall teichoic acid from subsp. as a species-specific marker.

Cell walls of the three subsp. strains, DSM 43377, 43378 and 43120 contain structurally identical teichoic acids. The cell wall of each strain has three distinct types of teichoic acids: (1) unsubstituted 3,5-poly(ribitol phosphate), (2) 1,3-poly(glycerol phosphate) partially substituted at C-2 with α--acetylglucosamine residues, and (3) 1,5-poly(ribitol phosphate) with each ribitol unit carrying a 2,4-pyruvate ketal group.

[The role of anesthesiologists in the intensification of the activities of the surgical department].

The authors have widened the volume of clinical, biochemical and functional examinations of patients and introduced the examination by the anesthesiologist and other specialists under ambulatory conditions. The patients having concomitant diseases were given the necessary treatment at the prehospital stage. Most of the patients were operated upon in the day of their admission.
