The type VI secretion system (T6SS) is widely distributed in pathogenic Proteobacteria. Sequence and structural analysis of T6SS reveals a resemblance to the T4 bacteriophage tail, in which an outer sheath structure contracts an internal tube for injecting nucleic acid into bacterial cells. However, the molecular details of how this phage tail-like T6SS structure is assembled in vivo and execut...

AIM To report the presentation of complex regional pain syndrome-1 (CRPS-1) as deQuervain's stenosing tenosynovitis (DQST). CASE REPORT A 24-year-old woman presented with 3-year history of clinical diagnostic criteria (CDC) of CRPS-1. Conservative and surgical treatment for this as DQST had failed to relieve her. We diagnosed the problem as CRPS-1with CDC as inflammatory manifestations of a m...

BACKGROUND Inflammatory cells are believed to play a prominent role during tissue repair and remodeling. Since repair processes develop and mature over extended time frames, the present study was designed to evaluate the effect of monocytes and fibroblasts in prolonged culture in three-dimensional collagen gels. METHODS Blood monocytes from healthy donors and human fetal lung fibroblasts were...

PURPOSE One of the aims of the treatment in ambulant cerebral palsy (CP) patients is improvement of gait. The level of gait pathology is assessed by instrumented gait analysis, including surface electromyography. The aim of this study was to investigate the relation of the abnormality level of the gait and the co-contraction of the agonist-antagonist muscles, and relation between symmetry left ...

in this paper, we establish and prove the existence of best proximity points for multivalued cyclic $f$- contraction mappings in complete metric spaces. our results improve and extend various results in literature.

recently, choudhury and metiya [fixed points of weak contractions in cone metric spaces, nonlinear analysis 72 (2010) 1589-1593] proved some fixed point theorems for weak contractions in cone metric spaces. weak contractions are generalizations of the banach's contraction mapping, which have been studied by several authors. in this paper, we introduce the notion of $f$-weak contractions and als...

This study examines the temperature-dependent evolution of lattice constants for various CuAl2-type compounds, including NiZr2, (Co,Rh,Ir)Zr2, (Fe,Co,Rh,Ir)Zr2, and (Co,Ni,Cu,Rh,Ir)Zr2, in pursuit negative or zero thermal expansion. Results reveal that NiZr2 has positive expansion, while other compounds exhibit uniaxial expansion along c-axis contraction. The suggests can be controlled by manip...
