BACKGROUND Video-assisted thoracic sympathicotomy plays an important for the treatment of essential hyperhidrosis. Patients are usually satisfied with the surgical outcome at the early post-operative period, but suffer recurrence and compensatory sweating in the late post-operative period. There are many sympathicotomy methods to minimize recurrence and compensatory sweating. We compared the ou...

An immediate-early (IE) gene of human herpesvirus 6 (HHV-6), U95, has similarity at the amino acid level to the murine cytomegalovirus (MCMV) IE2 gene and is related to the human cytomegalovirus (HCMV) US22 gene family. Sequence analyses of U95 cDNA clones revealed that the transcription start site was located about 1.6 kbp upstream of the putative initiating ATG and that the transcript consist...

On input a random 3-CNF formula of clauses-to-variables ratio r3 applies repeatedly the following simple heuristic: Set to True a literal that appears in the maximum number of clauses, irrespective of their size and the number of occurrences of the negation of the literal (ties are broken randomly; 1-clauses when they appear get priority). We prove that for r3 < 3.42 this heuristic succeedswith...

Here, u(t,x) ∈ R3 denotes the velocity of the fluid at a point x ∈ and time t ∈ [0,T ]; w(t,x) ∈ R3, b(t,x) ∈ R3 and p(t,x) ∈ R denote, respectively, the micro-rotational velocity, the magnetic field and the hydrostatic pressure; the constants μ,χ,α,β,γ,j , and ν are positive numbers associated to properties of the material; f (t,x), g(t,x) ∈ R3 are given external fields. We assume that on the ...

Group B streptococci (GBS) are important human and bovine pathogens which can be classified by a variety of phenotype- and gene-based techniques. The capsular polysaccharide and strain-variable, surface-anchored proteins are particularly important phenotypic markers. In an earlier study, a previously unrecognized protein antigen called Z was described. It was expressed by 27.2% of GBS strains f...

Ral is a small Ras-like GTPase that regulates membrane trafficking and signaling. Here, we show that in response to planar cell polarity (PCP) signals, Ral modulates asymmetric Notch signaling in the Drosophila eye. Specification of the initially equivalent R3/R4 photoreceptor precursor cells in each developing ommatidium occurs in response to a gradient of Frizzled (Fz) signaling. The cell wit...

We give a simple explanation of numerical experiments of V. Arnold with two sequences of symmetric numerical semigroups, S(4, 6 + 4k, 87− 4k) and S(9, 3 + 9k, 85− 9k) generated by three elements. We present a generalization of these sequences by numerical semigroups S(r 1 , r1r2 + r 2 1k, r3 − r 2 1k), k ∈ Z, r1, r2, r3 ∈ Z , r1 ≥ 2 and gcd(r1, r2) = gcd(r1, r3) = 1, and calculate their univers...

(1) r3(n) = 4πn S3(n), where the singular series S3(n) is given by (16) with Q = ∞. While in principle this exact formula can be used to answer almost any question concerning r3(n), the ensuing calculations can be tricky because of the slow convergence of the singular series S3(n). Thus, one often sidesteps (1) and attacks problems involving r3(n) directly. For example, concerning the mean valu...

The expression pattern of the fibroblast growth factor receptor Fgf-R1, R2 and R3 genes was studied in the chicken spinal cord using in situ hybridization (ISH). Unlike Fgf-R1 which is widely expressed in motoneurons, Fgf-R3 is expressed in a subset of motoneurons in the medial subdivision of the median motor column (MMCm) that also express Islet-1 and Lim-3. The motoneuron identity of the labe...

La inoculación con rizobios y hongos micorrízicos arbusculares (HMA), de manera simple o combinada, puede contribuir el crecimiento establecimiento Prosopis laevigata por una interacción positiva los simbiontes la planta. El objetivo fue evaluar efecto combinada tres aislados locales (R1, R2 R3) dos cepas HMA (HMA1 HMA2) en colonización micorrízica, nodulación, producción biomasa P. sustrato pH...
