pulmonary arteriopathy and idiopathic pulmonary arterial hypertension in six dogs.pulmonary arteriopathy (pa) is the pathologic hallmark in human medicine of diffuse constrictive (medial and intimal remodeling) or multifocal complex (plexiform and dilatative lesions) arterial lesions, or both, that lead to irreversible obliteration of the arterial lumen. clinically, pa leads to pulmonary arterial hypertension (pah), of which idiopathic (ipah) is one of the 5 subsets, and ultimately, to right-sided heart failure (rhf). clinical and pathologic findings from 6 dogs with diagnosi ...200616846993
governing stem cell research in california and the usa: towards a social infrastructure.owing to the restrictive human embryonic stem cell (hesc) policies of the us government, the question of whether to pursue human embryonic stem cell experiments has dominated the ethical and political discourse concerning such research. explicit attention must now turn to problems of implementing the research on a large scale: in the 2004 us elections, california voters approved a state initiative for stem cell research, earmarking $3 billion in direct spending over 10 years. this article explor ...200616843559
a framework for assessing the impact of land use policy on community exposure to air toxics.our research focuses on the linkage between land use planning policy and the spatial pattern of exposure to air toxics emissions. our objective is to develop a modeling framework for assessment of the community health risk implications of land use policy. the modeling framework is not intended to be a regulatory tool for small-scale land use decisions, but a long-range planning tool to assess the community health risk implications of alternative land use scenarios at a regional or subregional sc ...200716842900
widespread occurrence of phage-encoded exotoxin genes in terrestrial and aquatic environments in southern california.many human diseases are caused by pathogens that produce exotoxins. the genes that encode these exotoxins are frequently encoded by mobile dna elements such as plasmids or phage. mobile dna elements can move exotoxin genes among microbial hosts, converting avirulent bacteria into pathogens. phage and bacteria from water, soil, and sediment environments represent a potential reservoir of phage- and plasmid-encoded exotoxin genes. the genes encoding exotoxins that are the causes of cholera, diphth ...200616842371

coliform bacteria in sierra nevada wilderness lakes and streams: what is the impact of backpackers, pack animals, and cattle?the presence of coliform bacteria indicates a watershed risk for harboring microbes capable of causing human disease. we hypothesized that water from watersheds that have different human- or animal-use patterns would have differing risks for the presence of coliform bacteria. methods; water was collected in wilderness areas of the sierra nevada range in california. a total of 60 sites from lakes or streams were selected to statistically differentiate the risk categories: 1) high use by backpacke ...200616538940
mother's milk and the muffin man: grassroots innovations in medical marijuana delivery systems.in the ongoing debates over medical marijuana, opponents often conflate the alleged risks of cannabis therapeutics with the acknowledged harms associated with smoking. although smoking is the most widely used method of administering marijuana, it is not the only available means. this paper provides an account of the production, distribution, and administration of non-smokable cannabis products by members of a california health care collective, the wo/men's alliance for medical marijuana. wamm ha ...200516537333
outcomes of clinical and surgical assessment of women with pathological nipple discharge.there is no consensus about the diagnostic approach to pathologic nipple discharge (pnd). we hypothesize that lactiferous duct excision (microdochectomy) or image-guided biopsy are safe and effective means of diagnosis of pnd. eighty-two patients with pnd underwent history and physical exam followed by breast sonography and mammogram. image-guided biopsy was done if imaging studies were positive, whereas microdochectomy was done if normal. discharge was unilateral (96%), bloody (79%), and sponta ...200616536240
babesia conradae, sp. nov., a small canine babesia identified in california.small piroplasms as a cause of canine babesiosis have usually been identified as babesia gibsoni. recent genetic studies suggested that small piroplasms are more likely comprised of at least three genotypically distinct species. in southern california, canine babesiosis caused by a small piroplasm has been documented since 1990. morphological characteristics of this parasite include a small (0.3-3.0 microm) intraerythrocytic merozoite stage with predominantly ring, piriform, tetrad, amoeboid, or ...200616524663
assessing societal impacts when planning restoration of large alluvial rivers: a case study of the sacramento river project, california.studies have shown that ecological restoration projects are more likely to gain public support if they simultaneously increase important human services that natural resources provide to people. river restoration projects have the potential to influence many of the societal functions (e.g., flood control, water quality) that rivers provide, yet most projects fail to consider this in a comprehensive manner. most river restoration projects also fail to take into account opportunities for revitaliza ...200616523370
a review of the small canine piroplasms from california: babesia conradae in the literature.small piroplasms as a cause of canine babesiosis in southern california were first documented in 1990. initially these piroplasms were considered to be babesia gibsoni, the only small babesia parasite known to infect dogs at that time. in the following decade, the use of molecular analysis made it clear that small canine babesia in fact are comprised of at least three distinct species, and the isolates from dogs in southern california were not b. gibsoni. molecular, antigenic, and morphological ...200616522352
a dietary risk assessment of the pyrethroid insecticide resmethrin associated with its use for west nile virus mosquito vector control in california.an outbreak of human illnesses associated with west nile virus (wnv) occurred in new york city in 1999. since then, it has gradually spread westwards, reaching northern california for the first time in 2005. wnv is transmitted by several mosquito species and birds serve as the main reservoir. several control measures have been used, targeting both the aquatic larvae and the adult mosquitoes. in the latter case, roosting birds in trees are sprayed with pyrethroid insecticides because these are hi ...200616518516

endothelial nitric oxide synthase (nos3) genetic variants, maternal smoking, vitamin use, and risk of human orofacial clefts.orofacial clefts have been associated with maternal cigarette smoking and lack of folic acid supplementation (which results in higher plasma homocysteine concentrations). because endothelial nitric oxide synthase (nos3) activity influences homocysteine concentration and because smoking compromises nos3 activity, genetic variation in nos3 might interact with smoking and folic acid use in clefting risk. the authors genotyped 244 infants with isolated cleft lip with or without cleft palate (cl/p), ...200516269583
peripheral tuberculous lymphadenitis: epidemiology, diagnosis, treatment, and outcome.we reviewed 106 patients referred to our institution for treatment of peripheral tuberculous adenitis to establish the epidemiologic, clinical, and pathologic manifestations of this disease. tuberculous lymphadenitis occurred predominantly in young, foreign-born women a mean of 5 years after arrival in the united states. tuberculin skin tests were positive in 94% of cases. lymphadenopathy occurred most frequently in the neck (57%) or supraclavicular area (26%) and involved 1-3 nodes. forty (38%) ...200516267410
detection of breastfeeding and weaning in modern human infants with carbon and nitrogen stable isotope ratios.carbon ((13)c/(12)c) and nitrogen ((15)n/(14)n) stable isotope ratios were longitudinally measured in fingernail and hair samples from mother-infant pairs where infants were exclusively breastfed (n = 5), breast- and formula-fed (n = 2), or exclusively formula-fed (n = 1) from birth. all exclusively breastfed infants had a dual enrichment in carbon ( approximately 1 per thousand) and nitrogen ( approximately 2-3 per thousand) when compared to maternal values. in contrast, breast- and formula-fed ...200616261548
apolipoprotein a-v: a potential modulator of plasma triglyceride levels in turks.the apolipoprotein a-v gene (apoa5) plays an important role in determining plasma triglyceride levels. we studied the effects of apoa5 polymorphisms on plasma triglyceride levels in turks, a population with low levels of hdl cholesterol and a high prevalence of coronary artery disease. we found 15 polymorphisms, three of which were novel. seven haplotype-tagging single nucleotide polymorphisms (snps) were chosen and genotyped in approximately 3,000 subjects. the rare alleles of the -1464t>c, -11 ...200616258166
a known functional polymorphism (ile120val) of the human pcmt1 gene and risk of spina bifida.folate binding protein 1 (folr1) knockout mice with low maternal folate concentrations have been shown to be excellent animal models for human folate-responsive neural tube defects (ntds). previous studies using the folr1 knockout mice revealed that maternal folate supplementation up-regulates the expression of the pcmt1 gene in folr1 nullizygous neural tube tissue during neural tube closure. pcmt1 encodes the protein repair enzyme l-isoaspartate (d-aspartate) o-methyltransferase (pimt) that con ...200616256389
