BACKGROUND: White matter (WM) abnormalities associated with prematurity are one of the most important causes of neurological disability that involves spastic motor deficits in preterm newborns. This study aimed to evaluate regional microstructural changes in diffusion tensor imaging (DTI) associated with WM abnormalities. METHODS: We prospectively studied extremely low birth weight (ELBW; <1000 g) preterm infants who were admitted to the Neonatal Intensive Care Unit of Hanyang University Hospital between February 2011 and February 2014...

Preterm infants are susceptible to inflammation-induced white matter injury but the exposures that lead to this are uncertain. Histologic chorioamnionitis (HCA) reflects intrauterine inflammation, can trigger a fetal inflammatory response, and is closely associated with premature birth. In a cohort of 90 preterm infants with detailed placental histology and neonatal brain magnetic resonance imaging (MRI) data at term equivalent age, we used Tract-based Spatial Statistics (TBSS) to perform voxel-wise statistical comparison of fractional anisotropy (FA) data and computational morphometry analysis to compute the volumes of whole brain, tissue compartments and cerebrospinal fluid, to test the hypothesis that HCA is an independent antenatal risk factor for preterm brain injury...

AIM: To identify factors of motor recovery in ischemic stroke (IS) using diffusion tensor imaging (DTI). MATERIAL AND METHODS: Forty-seven patients with IS were studied within 1-2, 7-8, 14-15, 20-21 days after stroke. The fractional anisotropy (FA) values of the pyramidal tract were measured in the posterior limb of the internal capsule, cerebral peduncle and pons. Relative values of FA (rFA) ratio (rFA=FA affected side/FA unaffected side) were assessed as well...

Pathogenic fungi kill an estimated 1.3 million people each year. This number is predicted to rise as drug resistance spreads, thus antifungal drugs with novel modes of action are urgently required. Fungal endoglycoceramidase-related proteins 1 and 2 (EGCrP-1 and -2), which hydrolyse glucosylceramide and ergosteryl beta-glucoside, respectively, are important for fungal cell growth and have been identified as potential targets for drug development. A library of iminosugar derivatives was screened against EGCrP-1 and -2, thereby identifying a number of competitive inhibitors with nanomolar affinities...

The use of amphotericin B (AmB) in conjunction with 5-fluorocytosine (5-FC) is known to be the optimal therapy for treating cryptococcosis, but the mechanism by which 5-FC synergizes with AmB is unknown. In this study, we generated a Cryptococcus neoformans ura1Δ mutant lacking dihydroorotate dehydrogenase (DHODH), which demonstrated temperature-sensitive growth due to a defect in cell integrity and sensitivity to cell wall-damaging agents. In addition, sensitivity to AmB was greatly increased. Inclusion of uracil or uridine in the medium did not suppress the cell wall or AmB phenotype, whereas complementation with the wild-type URA1 gene complemented the mutant phenotype...

Exosomes are nano-sized vesicles that facilitate intercellular communications through carrying genetic materials and functional biomolecules. Owing to their unique size and structure, exosomes have emerged as a useful tool to overcome the limitations of siRNA delivery. The use of exosomes as siRNA delivery vehicles lacks certain disadvantages of the existing foreign delivery systems such as viruses, polycationic polymers and liposomes, and introduces several advantages including inherent capacity to pass through biological barriers and escape from phagocytosis by the reticuloendothelial system, as well as being biocompatible, non-toxic, and immunologically inert...

Scientific approaches for dispensation are important for the quality and efficacy of drug treatments. Therefore, for the dispensation of powdered medicines, we have developed a powder blending method using a planetary centrifugal mixer (PCM) to replace the empirical manual method involving a mortar and pestle. The aim of this study was to optimize the formulation of pharmaceutical diluents for dispensing powdered medicines, using PCM. The diluents, composed of powdered lactose, crystalline lactose, and corn starch were assigned to a {3,2}-Simplex Lattice design...

Fitz-Hugh-Curtis syndrome (FHCS) is a condition characterized by inflammation of the liver capsule (perihepatitis) and adjacent peritoneal surfaces. We report a case of FHCS developing in a peritoneal dialysis (PD) patient in whom catheter removal due to recurrent peritonitis was complicated by post-operative wound infection. To the best of our knowledge, this is the first case description of FHCS in the context of PD.

A new nanocomposite membrane was used to clean up impurities from complex samples and the obvious synergy was obtained in this paper. The nanocomposite membrane was prepared by dispersing TiO2 nanoparticles in chloroform and filled in the pores and lumen of polyether sulfone membrane fiber. The novel microextraction method showed the ideal selective extraction effect for alkaloids in the formulae composed of Rhizoma coptidis and the excellent clean-up efficiency compared with the single membrane method. The optimum extraction conditions were as follows: chloroform as accepted phase; the number of nanocomposite membrane fiber bars, 7; extraction time, 30 min; pH of the sample solution, 10...

The leaf-cutting ant Atta sexdens Forel (Hymenoptera: Formicidae) is one of the most damaging agricultural pests in the Neotropics. Management strategies predominantly rely on the use of general insecticides. What is needed are more species-specific and environmentally friendly options. Parasitioids such as phorid flies (Diptera: Phoridae) may be one such option, but a greater understanding of the ecology of the flies and their ant hosts is essential to devise biological control strategies. Here we report parasitism rates, ant host size, parasitoid abundance per host and resultant sex ratios of two phorid species Apocephalus attophilus Borgmeier and Eibesfeldtphora tonhascai Brown parasitizing A...

OBJECTIVE The role of tractography in Gamma Knife thalamotomy (GK-T) planning is still unclear. Pyramidal tractography might reduce the risk of radiation injury to the pyramidal tract and reduce motor complications. METHODS In this study, the ventralis intermedius nucleus (VIM) targets of 20 patients were bilaterally defined using Iplannet Stereotaxy Software, according to the anterior commissure-posterior commissure (AC-PC) line and considering the localization of the pyramidal tract. The 40 targets and tractography were transferred as objects to the GammaPlan Treatment Planning System (GP-TPS)...

There are no ideal means for the diagnosis of intestinal bleeding diseases as of now, particularly in the small intestine. This study investigated an intelligent intestinal bleeding detection capsule system based on color recognition. After the capsule is swallowed, the bleeding detection module (containing a color-sensitive adsorptive film that changes color when absorbing intestinal juice,) is used to identify intestinal bleeding features. A hue-saturation-light color space method can be applied to detect bleeding according to the range of H and S values of the film color...

Movement skill difficulties in children [or developmental coordination disorder (DCD)] often persist into adulthood (in up to 70% of cases). The suggestion of white matter microstructure alterations in children with DCD raises the question of whether similar alterations are present in adults with probable DCD (pDCD). Twelve adults with pDCD and 11 adults without pDCD underwent diffusion tensor imaging. The results showed that the pDCD group had significantly lower fractional anisotropy in the corticospinal tract and superior longitudinal fasciculus and lower mean diffusivity in the internal capsule and inferior longitudinal fasciculus...

PURPOSE: The treatment of gluteal muscle contracture (GMC) after failed primary open release surgery has rarely been reported in the literature. GMC is a troublesome health problem in some developing countries, and it can result in the limitation of patients' hip function, leading to the development of inferiority complexes. The aim of this study is to evaluate the effect of arthroscopic revision surgery after failed primary open release on patients with GMC. METHODS: A total of 278 hips of 140 patients who underwent arthroscopic revision procedures after failed primary open surgeries were gathered from the department files...
