Purified murein from Thiobacillus neapolitanus was poorly digested by lysozyme. It's sensitivity to the enzyme greatly increased after N-acetylation. The murein was found to contain 30 to 35% glucosamine residues lacking N-acetyl groups. It also contained phosphomuramic acid. Further modifications included amidation of diaminopimelic acid in the peptide side chains and a low alanine content. None of these modifications were found in the murein of another sulphur bacterium, Thiobacillus versutus. 相似文献

Magnetic Resonance Diffusion Tensor Imaging (DTI) of the control and traumatic injured spinal cord of a rat in vitro is reported. Experiments were performed on excised spinal cords from 10 Wistar rats, using a home-built 6.4 T MR microscope. MRI and histopathological results were compared. Presented results show that DTI of the spinal cord, perfused with formalin 10 minutes after the injury, can detect changes in water diffusion in white matter (WM) and in gray matter (GM), in areas extending well beyond the region of direct impact. Histology of neurons of the GM shows changes that can be attributed to ischemia. This is in agreement with the observed decrease of diffusion in the injured regions, which may be attributed to the cytotoxic edema due to ischemia. However, the diffusion changes in highly anisotropic WM seem to be caused by a direct action of mechanical force of impact, which significantly distorts the nerve fibers. 相似文献

Usually neglected is the role of neutrophils in causing of immunological disturbances in patients with multiple sclerosis (MS). Nevertheless, it has been indicated over the recent years that these cells possess a sufficient potential to affect both immune response and inflammation. This potential may result in MS through the process of priming of these cells by proinflammatory cytokines like TNF. We studied TNF and its soluble receptors sp55 and sp75 serum levels and binding of fluorescein isothiocyanate (FITC)-stained TNF by neutrophils. We studied three different groups of MS patients: 10 patients in relapse of the disease, 13 in its remission, and 11 in its chronic progressive form (CP-MS). The control was provided by 14 neurological patients (OND) with non-inflammatory diseases. The performed studies showed higher TNF sp55 and sp75 soluble TNF receptors serum levels in the patients with relapse, comparing with other MS patients and OND. TNF binding by neutrophils of MS patients during relapse was also higher, than other MS patients and OND. These result suggest the preactivation of neutrophils in the relapse of MS. 相似文献

Paternal involvement in children's lives is associated with a variety of child outcomes, including improved cognition, improved mental health, reduced obesity rates, and asthma exacerbation. Given this evidence, the American Academy of Pediatrics has promoted actions by pediatricians to engage fathers in pediatric care. Despite these recommendations, the mother–child dyad, rather than the mother–father–child triad, remains a frequent focus of care. Furthermore, pediatric care is often leveraged to improve maternal health, such as screening for maternal depression, but paternal health is infrequently addressed even as men tend to exhibit riskier behaviors, poorer primary care utilization, and lower life expectancy. Therefore, increasing efforts by pediatric clinicians to engage fathers may affect the health of both father and child. These efforts to engage fathers are informed by currently used definitions and measures of father involvement, which are discussed here. Factors described in the literature that affect father involvement are also summarized, including culture and context; interpersonal factors; logistics; knowledge and self-efficacy; and attitudes, beliefs, and incentives. Innovative ways to reach fathers both in the clinic and in other settings are currently under investigation, including use of behavior change models, motivational interviewing, mobile technologies, peer support groups, and policy advocacy efforts. These modalities show promise in effectively engaging fathers and improving family health. 相似文献
