Mechanisms Linking White Matter Lesions,Tract Integrity,and Depression in Alzheimer Disease

ObjectiveLate-life depression involves the disconnection of white matter tracts that regulate mood. A pathogenic link between poor tract integrity and depressive symptoms is believed to be white matter lesions (WML), however the mechanisms linking tract integrity, WML, and depression remains unexplored. The authors sought to identify whether the association between reduced tract integrity and depressive symptoms is mediated by WML in patients with Alzheimer disease (AD), and whether individual characteristics moderate this effect.MethodsThis was a cross-sectional study in a tertiary memory clinic. A total of 91 patients with mild AD and 79 healthy elderly, comparable in depressive symptoms, white matter hyperintensities (WMH) volume, cardiovascular risk, age, and sex were chosen. Tract integrity was assessed using diffusion tensor imaging, WML were indexed as WMH, measured using fluid-attenuation inversion recovery imaging, and depressive symptoms were measured with the informant-based Geriatric Depression Scale.ResultsIn patients with mild AD, reduced tract integrity in right hemispheric cortical-subcortical tracts and the genu of the corpus callosum was moderately associated with depressive symptoms. This association was fully mediated by WML. Moderation analysis indicated that old age strengthened the association between all tracts and depressive symptoms, as mediated by WML. In cognitively healthy elderly, neither tracts nor WML were related to depressive symptoms.ConclusionReduced tract integrity may be important but not sufficient for the manifestation of depressive symptoms in mild AD. Instead, WML may drive the pathogenic link between reduced tract integrity and depressive symptoms.     

Host range, growth property, and virulence of the smallpox vaccine: vaccinia virus Tian Tan strain

Vaccinia Tian Tan (VTT) was used as a vaccine against smallpox in China for millions of people before 1980, yet the biological characteristics of the virus remain unclear. We have characterized VTT with respect to its host cell range, growth properties in vitro, and virulence in vivo. We found that 11 of the 12 mammalian cell lines studied are permissive to VTT infection whereas one, CHO-K1, is non-permissive. Using electron microscopy and sequence analysis, we found that the restriction of VTT replication in CHO-K1 is at a step before viral maturation probably due to the loss of the V025 gene. Moreover, VTT is significantly less virulent than vaccinia WR but remains neurovirulent in mice and causes significant body weight loss after intranasal inoculation. Our data demonstrate the need for further attenuation of VTT to serve either as a safer smallpox vaccine or as a live vaccine vector for other pathogens.

Hypersensitivity to histamine and systemic anaphylaxis in mice with pharmacologic beta adrenergic blockade: protection by nucleotides.

The effects of exogenous nucleotides on the histamine hypersensitivity of pharmacologically beta-blocked mice were investigated. Female HLA-SW (ICR) mice, 27-29 gm, were injected intraperitoneally with 20 to 100 mug of propranolol 45 min before intraperitoneal challenge with 1 mg histamine. These animals had a mortality which averaged approximately 80%. At various time intervals before histamine, doses of from 0.5 to 12 mumoles of nucleotides were administered intravenously. Noncyclic nucleotides, adenosine, adenosine 5'-monophosphate (AMP), and guanosine 5'-monophosphate (GMP) showed clear, dose-response protection against histamine death of propranolol-treated mice when they were given 45 to 90 min before histamine. Cyclic AMP showed significant protection only when it was given at a dose of 8 mumoles 45 to 90 min before histamine, and lower or higher doses gave equivocal or no protection. Cyclic GMP WAS Not protective at any dose tested. Propranolol treatment also produced enhanced sensitivity to passive systemic anaphylaxis. Mice were passively sensitized by intraperitoneal injection of mouse anti-egg albumin antibody 6 hr before intravenous challenge with 0.5 mg egg albumin. The mortality from anaphylaxis in the group treated with 20 mug propranolol 45 min before antigen challenge increased to 83%, while that of the group not given propranolol was only 10%. Nucleotides were given intravenously 45 min before antigen challenge. The nucleotides that protected mice from death due to histamine challenge also protected them from death due to systemic anaphylaxis. These protective nucleotides were the same nucleotides that had been reported previously to be protective against Bordetella pertussis-induced hypersensitivity to histamine and anaphylaxis.     

Metabolic urinary profiling of alcohol hepatotoxicity and intervention effects of Yin Chen Hao Tang in rats using ultra-performance liquid chromatography/electrospray ionization quadruple time-of-flight mass spectrometry

This paper was designed to study metabonomic characters of the hepatotoxicity induced by alcohol and the intervention effects of Yin Chen Hao Tang (YCHT), a classic traditional Chinese medicine formula for treatment of jaundice and liver disorders in China. Urinary samples from control, alcohol- and YCHT-treated rats were analyzed by ultra-performance liquid chromatography/electrospray ionization quadruple time-of-flight mass spectrometry (UPLC/ESI-QTOF-MS) in positive ionization mode. The total ion chromatograms obtained from the control, alcohol- and YCHT-treated rats were easily distinguishable using a multivariate statistical analysis method such as the principal components analysis (PCA). The greatest difference in metabolic profiling was observed from alcohol-treated rats compared with the control and YCHT-treated rats. The positive ions m/z 664.3126 (9.00 min) was elevated in urine of alcohol-treated rats, whereas, ions m/z 155.3547 (10.96 min) and 708.2932 (9.01 min) were at a lower concentration compared with that in urine of control rats, however, these ions did not indicate a statistical difference between control rats and YCHT-treated rats. The ion m/z 664.3126 was found to correspond to ceramide (d18:1/25:0), providing further support for an involvement of the sphingomyelin signaling pathway in alcohol hepatotoxicity and the intervention effects of YCHT.
