Multidonor FMT capsules improve symptoms and decrease fecal calprotectin in ulcerative colitis patients while treated - an open-label pilot study.

Background: Growing evidence indicates that gut dysbiosis is a factor in the pathogenesis of ulcerative colitis (UC). Fecal microbiota transplantation (FMT) appears to be promising in inducing UC remission, but there are no reports regarding administration using capsules. Methods: Seven patients with active UC, aged 27-50 years, were treated with 25 multidonor FMT capsules daily for 50 days as a supplement to their standard treatment in an open-label pilot study. The primary objective was to follow symptoms through the Simple Clinical Colitis Activity Index (SCCAI). Secondary objectives were to follow changes in fecal calprotectin and microbial diversity through fecal samples and quality of life through the Inflammatory Bowel Disease Questionnaire (IBDQ). Participants were followed through regular visits for six months. Results: From a median of 6 at baseline, the SCCAI of all participants decreased, with median decreases of 5 (p = .001) and 6 (p = .001) after 4 and 8 weeks, respectively. Three of the seven patients had flare-up/relapse of symptoms after the active treatment period. The median F-calprotectin of ≥1800 mg/kg at baseline decreased significantly during the treatment period, but increased again in the follow-up period. The median IBDQ improved at all visits compared to baseline. The fecal microbiota α-diversity did not increase in the study period compared to baseline. All participants completed the treatment and no serious adverse events were reported. Conclusion: Fifty days of daily multidonor FMT capsules temporarily improved symptoms and health-related life quality and decreased F-calprotectin in patients with active UC.

Effects of feeding finisher pigs with chicory or lupine feed for one week or two weeks before slaughter with respect to levels of Bifidobacteria and Campylobacter.

This study aimed to assess whether inclusion of chicory or lupine (prebiotics) in the diet of pre-slaughter pigs for just 1 or 2 weeks could change the composition of their intestinal microbiota, stimulate the growth of bifidobacteria and help to lower the amount of thermoplilic Campylobacter spp. (mainly Campylobacter jejuni and Campylobacter coli), which are a major cause of food-borne infections in humans. A total of 48 pigs that had an initial live weight of 90 kg were fed with either a lupine (organic concentrate with 25% blue lupine seeds), chicory (organic concentrate with 10% dried chicory roots) or control (100% organic concentrate) diet for 1 week (24 pigs) or 2 weeks (24 pigs) before slaughter. The Campylobacter spp. level in rectal faecal samples after 0, 1 and 2 weeks of feeding and in the luminal content from ileum, caecum and colon at slaughter was determined by direct plating on modified charcoal-cefoperazone-deoxycholate agar plates. DNA extracted from the luminal content of distal ileum and caecum was used for terminal restriction fragment length polymorphism (T-RFLP) analysis of the composition of intestinal microbiota and for measuring the amount of bifidobacterial and total bacterial DNA by quantitative real-time PCR (qPCR). Campylobacter spp. were excreted by all pigs and present in the luminal content from distal ileum to midway colon with particularly high numbers in the caecum, but the excretion was reduced by 10-fold in pigs fed lupines for 1 week as compared with control- and chicory-fed pigs (mean log(10) 2.9 v. 4.1 CFU/g; P < 0.05). The qPCR analysis showed that feeding with lupines resulted in higher levels of bifidobacteria in caecum as compared with the other diets (P < 0.05). T-RFLP analysis showed that four of the most abundant bacteria with terminal restriction fragment values >5% relative to the intensity of total abundance differed between the feed treatments (P < 0.05). Therefore, this study showed that even a short-term alternative feeding strategy with prebiotics in the diet of pre-slaughter pigs elicited changes in the composition of the intestinal microbiota, where lupine increased the level of bifidobacteria in caecum and reduced the Campylobacter spp. excretion level after 1 week.

Antimicrobial activity of cyclodextrin entrapped allyl isothiocyanate in a model system and packaged fresh-cut onions.

The aim of this work was to determine the antimicrobial effect of allyl isothiocyanate (AIT) entrapped in alpha and beta cyclodextrin inclusion complexes (ICs). In model experiments, AIT formulations were applied to filter paper discs fixed inside the lid of Petri dishes, where the agar surface was inoculated with the target organism (Penicillium expansum, Escherichia coli or Listeria monocytogenes). Solid phase microextraction coupled with gas chromatography was used to determine static headspace concentrations of AIT formulations. The antimicrobial effect of beta IC was determined during aerobic storage of packaged fresh-cut onions at 5 °C for 20 days. AIT entrapped in beta IC exhibited a significantly (p < 0.05) better antimicrobial effect compared to unentrapped AIT. AIT vapour concentrations in the static system were highest for unentrapped AIT followed by beta IC and alpha IC. Application of beta IC (200 µl/l) to packaged fresh-cut onions effectively decreased numbers of L. monocytogenes, which were also decreased at slower rates to undetectable levels on untreated cut onion. After 10 days, total aerobic counts were ca. 4 log CFU/g lower on onions treated with beta IC (100 and 200 µl/l) compared to untreated controls. This work demonstrates the utility of beta IC as an antimicrobial treatment with potential applications in packaged fresh-cut vegetable products.

Influence of the ability to roll the tongue and tongue-training parameters on oral motor performance and learning.

OBJECTIVE: Training of tongue function is an important part of rehabilitation of patients with brain damage. A standardized tongue-training task has been shown to induce cortical plasticity. This study tested the possible influence of the natural ability to roll the tongue and modulations of tongue-training parameters on tongue-training performance. DESIGN: A total of 44 healthy adult subjects participated. 29 subjects (15 with and 14 without ability to roll their tongue) performed 1h standard tongue-training task. Another 15 subjects participated in 2 sessions: Standard and Modulation in randomized order. Standard session: 1h tongue-training with fixed training parameters; Modulation session: 1h tongue-training with modulation of training parameters every 20 min (3 different settings - A, B, C, with different timing of task). Perceived task difficulty was evaluated on a 0-10 numerical rating scale (NRS). RESULTS: All participants improved performance during training (P<0.001). The ability to roll the tongue did not influence tongue-training performance (P=0.617). Modulation of training parameters influenced baseline training performance (P<0.018) and improvement (P=0.039). The mean perceived difficulty on NRS was: Standard: 6 ± 2; Modulation: A: 6 ± 2; B: 7 ± 1;C: 4 ± 1. Perceived task difficulty (ρ=-0.740, P<0.001) and performance improvement (ρ=-0.610, P<0.001) were inversely correlated with baseline training performance. CONCLUSION: The natural ability to roll the tongue did not influence tongue-training performance. Modulation of tongue-training parameters by alteration of timing of the training task influenced tongue-training performance and perceived task difficulty.

[Clinical diagnostics and therapy for non-arteritic central retinal artery occlusion]. / Diagnostik und Therapie beim nicht arteriitischen Zentralarterienverschluss.

Central retinal artery occlusion (CRAO) is an ophthalmological emergency situation. Known risk factors are arterial hypertension, cardial arrhythmia, arteriosclerosis, hypercholesterolemia and diabetes. Elderly patients should be examined for an arteritic genesis. Young patients (< 45 years) without typical risk factors may suffer from thrombophilia. There is no uniform recommendation on how to treat non-arteritic CRAO. Many different interventions have been suggested in the literature, i. e., massaging the eye, systemic or local reduction of intraocular pressure, anticoagulation, either systemically administered venous thrombolysis or supraselective intra-arterial thrombolysis. In this review we present the causes of CRAO and diagnostic means to detect causes; we also critically discuss previously described therapeutic options. It is our aim to provide a guide through the necessary interdisciplinary diagnostics in co-operation with internal medicine and neurology and to recommend a multimodal therapy in patients with non-arteritic CRAO.

Homeopathic prescribing for chronic conditions in equine veterinary practice in the UK.

Twelve Faculty of Homeopathy veterinarians recorded data systematically at 777 consecutive homeopathic appointments for horses over a period of 12 months. A spreadsheet enabled the recording of information, which included the date of appointment; horse and owner identity (anonymised); sex of horse; main medical problem treated; whether the condition was chronic or acute; whether the appointment was new or a follow-up; owner-assessed clinical outcome on a seven-point scale, ranging from -3 to +3, compared with the first appointment; homeopathic medicine(s) prescribed; and whether any conventional or other complementary/alternative medicine (CAM) was being used concurrently to treat the condition. Data from 289 horses comprised a total of 305 individual conditions identified as chronic in nature, of which 234 had a follow-up assessment. At the final appointment for chronic cases during the study period, 4.3 per cent were receiving conventional medication and 17.1 per cent were being given another CAM treatment in addition to homeopathy. The eight chronic conditions most frequently treated with homeopathy were: arthritis, headshaking, laminitis, chronic obstructive pulmonary disease, sweet itch, dermatitis, sarcoidosis and Cushing's syndrome.

Outcomes from homeopathic prescribing in veterinary practice: a prospective, research-targeted, pilot study.

BACKGROUND AND AIMS: Targeted research development in veterinary homeopathy is properly informed by the systematic collection and analysis of relevant clinical data obtained by its practitioners. We organised a pilot data collection study, in which 8 Faculty of Homeopathy veterinarians collected practice-based clinical and outcomes data over a 6-month period. METHODS: A specifically designed Excel spreadsheet enabled recording of consecutive clinical appointments under the following headings: date; identity of patient and owner (anonymised); age, sex and species of patient; medical condition/complaint treated; whether confirmed diagnosis, chronic or acute, new or follow-up case; owner-assessed outcome (7-point Likert scale: -3 to +3) compared with first appointment; homeopathic medicine/s prescribed; other medication/s for the condition/complaint. Spreadsheets were submitted monthly by e-mail to the project organisers for data checking, synthesis and analysis. RESULTS: Practitioners submitted data regularly and punctually, and most data cells were completed. 767 individual patients were treated (547 dogs, 155 cats, 50 horses, 5 rabbits, 4 guinea-pigs, 2 birds, 2 goats, 1 cow, and 1 tortoise). Outcome from two or more homeopathic appointments per patient condition was obtained in 539 cases (79.8% showing improvement, 6.1% deterioration, 11.7% no change; outcome not recorded in 2.4% of follow-ups). Strongly positive outcomes (scores of +2 or +3) were achieved in: arthritis and epilepsy in dogs and, in smaller numbers, in atopic dermatitis, gingivitis and hyperthyroidism in cats. CONCLUSIONS: Systematic recording of data by veterinarians in clinical practice is feasible and capable of informing future research in veterinary homeopathy. A refined version of the spreadsheet can be used in larger-scale research-targeted veterinary data collection.

Abeta1-42 promotes cholinergic sprouting in patients with AD and Lewy body variant of AD.

BACKGROUND: The neurodegenerative process in Alzheimer's disease (AD) and in the Lewy body variant of AD (LBV) patients is characterized by cholinergic dysfunction and deposition of amyloid beta-peptide (Abeta) 1-40 and 1-42; however, the differential effects of Abeta species on the cholinergic system are not completely clear. OBJECTIVE: To better understand the relationship between levels of Abeta1-40 and 1-42 on cholinergic deficits in AD and LBV patients. METHODS: Levels of choline acetyltransferase (ChAT) activity and ChAT immunoreactivity in the plaques in the frontal cortex of patients with AD and LBV were correlated with Abeta1-42 and 1-40 levels determined by ELISA and with neuropathologic and neurologic markers. RESULTS: Although the overall levels of ChAT activity were reduced in AD and LBV cases, there was a direct correlation with Abeta1-42 levels. Furthermore, patients with high Abeta1-42 levels had more abundant cholinergic dystrophic neurites in the plaques than cases with lower Abeta1-42. CONCLUSION: Abeta1-42 may also trigger cholinergic dysfunction by promoting aberrant neuritic sprouting.

Biodegradation of RDX within soil-water slurries using a combination of differing redox incubation conditions.

Biodegradation of 14C-tagged hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) was studied in aerobic, anaerobic, and anaerobic/aerobic slurries to identify the conditions maximizing RDX-mineralization in Cornhusker Army Ammunition Plant (CAAP, NE) groundwater. Supplementation with phosphate and adequate quantities of acetate caused 25% mineralization of RDX in 3 weeks by microorganisms native to CAAP. Under anaerobic conditions, the same supplementation resulted in 20% mineralization in 3 weeks and 30% mineralization in 6 weeks. The highest degree of mineralization (50%) was obtained under aerobic conditions when the contaminated groundwater was augmented with a consortium of three microbes isolated from another RDX contaminated soil (Hastings, NE) in addition to supplemented with phosphate and acetic acid. Use of complex organic sources (potato or corn starch) slowed down the rates of mineralization under anaerobic conditions, but rapid mineralization ensued as soon as the aerobic conditions were created. Final RDX concentrations in aqueous phase were below detection limit under most conditions. Assimilation of RDX by the cells was negligible.

Effect of interleukin 1beta on the HPA axis in H1-receptor knockout mice.

OBJECTIVES AND METHODS: Circulating cytokines such as interleukin-1 (IL-1), and tumor necrosis factor-alpha as well as lipopolysaccharide (LPS) are potent ACTH secretagogues, acting via stimulation of corticotropin-releasing hormone (CRH) and vasopressinergic neurons in the paraventricular nucleus of the hypothalamus (PVN). Histamine (HA) has been shown to stimulate ACTH secretion in rats, an effect in part mediated by CRH and arginine vasopressin (AVP). We have previously shown that inhibition of neuronal HA synthesis or central blockade of H(1) receptors (H(1)R) decreased the ACTH response to LPS in male rats. To further elucidate the role of neuronal HA in cytokine-induced activation of the HPA axis, we compared the effect of H(1)R knockout on IL-1beta-induced ACTH secretion in adult male mice. RESULTS: In H(1)R knockout mice, ACTH secretion increased from basal levels of 261 to 492 pmol/l in response to IL-1beta whereas the cytokine-induced ACTH secretion increased from 140 to 406 pmol/l in wild-type mice. Plasma corticosterone (CORT) rose from basal levels of 99 to 831 nmol/l in knockout mice upon IL-1beta stimulation, whereas in wild-type mice CORT levels rose from 112 to 841 nmol/l. There was no significant difference in IL-1beta-stimulated plasma ACTH or CORT levels between wild-type and knockout mice. Furthermore, there was no significant difference in basal or IL-1beta-stimulated hypothalamic levels of histamine and tele-methyl-histamine between wild-type and knockout mice. HDC gene expression was significantly lower in knockout mice than in wild-type mice both under basal and IL-1beta-stimulated conditions, while there were no significant differences in CRH gene expression in the PVN in knockout mice under basal and IL-1beta-stimulated conditions. Increased basal expression of AVP in the PVN of knockout mice was observed in this study compared to wild-type mice. CONCLUSION: We conclude that the lack of the gene for histamine H(1)R does not seem to be crucial for the ACTH and CORT response to IL-1beta, either due to possible functional compensation in the H(1)R knockout mouse or due to activation of pathways other than the neuronal histaminergic system.

Cholinergic deficits in the brains of patients with parkinsonism-dementia complex of Guam.

Patients with parkinsonism-dementia complex (PDC) of Guam showed moderate loss of choline acetyl transferase activity in the midfrontal and inferior parietal cortex, and severe loss in the superior temporal cortex. This deficit was similar to that seen in Alzheimer's disease and less severe than Lewy body disease. Thus, cholinergic deficits in the neocortex might contribute to some of the cognitive alterations in PDC of Guam.

A stable gas chromatography-mass spectrometry analysis system to characterize Ma Huang products found in health foods and supplements.

Herbal mixtures containing Ma Huang are of significant interest because of their popularity regardless of their potential health hazards. In spite of reports of health problems and even several deaths, these products are still frequently recommended for use. The complex nature of the commercial supplement mixtures has posed a problem in both their qualitative and quantitative analysis. A gas chromatographic procedure has been developed to evaluate authenticity of Ma Huang mixtures. Mass spectrometric identification of the six major alkaloid ephedrine components and application of chi-square evaluation of the chromatographic profile allows a determination to be made regarding the nature of the origin of the mixture. For comparison, a standard mixture was prepared that approximates a typical Ma Huang composition based on average amounts of each alkaloid component reported in the literature. The system is temperature stable and allows simultaneous analysis for caffeine and other components of the commercial supplements. Several samples of commercial herbal products were analyzed by the procedure, and their composition is evaluated and discussed.

Lipid oxidation in fish oil enriched mayonnaise: calcium disodium ethylenediaminetetraacetate, but not gallic acid, strongly inhibited oxidative deterioration.

The antioxidative effects of gallic acid, EDTA, and extra emulsifier Panodan DATEM TR in mayonnaise enriched with 16% fish oil were investigated. EDTA reduced the formation of free radicals, lipid hydroperoxides, volatiles, and fishy and rancid off-flavors. The antioxidative effect of EDTA was attributed to its ability to chelate free metal ions and iron from egg yolk located at the oil-water interface. Gallic acid reduced the levels of both free radicals and lipid hydroperoxides but promoted slightly the oxidative flavor deterioration in mayonnaise and influenced the profile of volatiles. Gallic acid may therefore promote the decomposition of lipid hydroperoxides to volatile oxidation products. Addition of extra emulsifier reduced the lipid hydroperoxide levels but did not influence the level of free radicals or the oxidative flavor deterioration in mayonnaisse; however, it appeared to alter the profile of volatiles. The effect of the emulsifier on the physical structure and rheological properties depended on the presence of antioxidants.

Altered expression of synaptic proteins occurs early during progression of Alzheimer's disease.

The expression levels of three synaptic proteins (synaptophysin, synaptotagmin, and growth-associated protein 43 [GAP43]) in AD cases clinically classified by Clinical Dementia Rating (CDR) score were analyzed. Compared with control subjects (CDR = 0), mild (early) AD (CDR = 0.5 to 1) cases had a 25% loss of synaptophysin immunoreactivity. Levels of synaptotagmin and GAP43 were unchanged in mild AD, but cases with CDR of >1 had a progressive decrement in these synaptic proteins. Thus, synaptic injury in frontal cortex is an early event in AD.

Choline acetyltransferase activity and cognitive domain scores of Alzheimer's patients.

Choline acetyltransferase activity and cognitive domain scores of Alzheimer's patients. Item scores from the Mattis Dementia Rating Scale (MDRS) and the Mini-Mental State Examination (MMSE) from 389 patients with probable Alzheimer's disease were submitted to principal component analysis with orthogonal rotation. The optimal solution identified four factors that reflected the cognitive domains of attention/registration, verbal fluency/reasoning, graphomotor/praxis and recent memory. A subgroup of patients was identified for whom both the MDRS and the MMSE had been administered within the 12 months before death. Scores were assigned to these patients for the four factors. These cognitive-domain scores were then correlated with postmortem choline acetyltransferase (ChAT) activity in the medial frontal cortex, inferior parietal cortex, and hippocampus. ChAT activity in both the medial frontal and the inferior parietal cortex significantly correlated with scores on the graphomotor/praxis factor. Medial frontal ChAT also correlated significantly with the attention/registration scores. Hippocampal ChAT correlated significantly only with recent memory scores. These results are consistent with current animal research regarding the effect of selective cholinergic lesions on behavior.

E4 allele dosage does not predict cholinergic activity or synapse loss in Alzheimer's disease.

OBJECTIVE: To investigate the relationship between apolipoprotein E (APOE) genotype and both cholinergic dysfunction and synapse loss in AD. BACKGROUND: A reduction in neocortical synapses and marked losses in the cholinergic system occur in AD. It has been suggested that the number of APOE epsilon4 alleles is inversely related to choline acetyltransferase (ChAT) activity, thereby influencing cholinergic function. Whether APOE genotype may influence neocortical synapse loss remains unclear. METHODS: An autopsy series of 182 patients with AD (National Institute on Aging and Consortium to Establish a Registry for Alzheimer's Disease criteria) and 16 normal controls (NC). APOE genotype was determined in blood samples or in postmortem brain tissue. Midfrontal synapse counts (AU/microg) were quantified by a dot-immunobinding assay for synaptophysin (Syn). Midfrontal ChAT activity (nmol/h/100 mg) was assessed using standard assays. RESULTS: Mean midfrontal ChAT activity and Syn were both significantly reduced in patients with AD compared with NC. The relationship between ChAT activity and number of epsilon4 allele copies in AD was complex, with ChAT activity lower in patients with either two or no epsilon4 alleles compared with those with one epsilon4 allele. There was no relationship between APOE genotype and synapse loss in AD. Syn density was almost identical across the three genotypes. CONCLUSIONS: Unlike other studies, we failed to detect a linear relationship between ChAT activity and number of epsilon4 allele copies in the midfrontal cortex of this large sample of patients with AD. Our data also show that the presence of epsilon4 allele does not influence midfrontal synapse loss in AD. This suggests that factors other than APOE genotype may be operative in the decline in midfrontal cholinergic function and synapses seen in AD.

Cholinergic dysfunction in diseases with Lewy bodies.

OBJECTIVE: To evaluate cholinergic activity in diseases with Lewy bodies (LB; LB variant of AD [LBV], diffuse LB disease [DLBD], and Parkinson's disease [PD]) to determine if 1) AD changes are requisite to cholinergic dysfunction, 2) cholinergic activity declines to the same extent in neocortical and archicortical areas, and 3) cholinergic loss is influenced by APOE genotype. BACKGROUND: Like AD, diseases with LB are associated with decreased choline acetyltransferase (ChAT) activity. Increased APOE epsilon4 allele frequency has been reported in LBV. Whether APOE genotype affects cholinergic function in LBV remains unclear. METHODS: An autopsy series of 182 AD (National Institute on Aging and Consortium to Establish a Registry for Alzheimer's Disease criteria), 49 LBV, 11 PD, 6 DLBD, and 16 normal control (NC) subjects. APOE genotype and ChAT activity (nmol/h/100 mg) in the midfrontal and hippocampal cortices were determined. RESULTS: Mean midfrontal ChAT activity was markedly reduced in diseases with LB (LBV: 53.3 +/- 39.0; PD: 54.8 +/- 35.7; DLBD: 41.3 +/- 24.8) compared to NC (255.4 +/- 134.6; p < 0.001) and AD (122.6 +/- 78.9; p < 0.05). Among diseases with LB, midfrontal ChAT activity was decreased to a similar extent in patients with (LBV) and without (DLBD and PD) AD pathology. Although mean ChAT activity for LBV was less than half that for AD in the midfrontal cortex, it was similar to that for AD in the hippocampus (LBV: 243.5 +/- 189.7; AD: 322.8 +/- 265.6; p > 0.05). However, hippocampal ChAT activity for both AD and LBV was lower than that for NC (666.5 +/- 360.3; p < 0.001). The epsilon4 allele dosage did not influence midfrontal ChAT activity in LBV. CONCLUSION: Marked losses in midfrontal ChAT activity occur in diseases with LB, independent of coexistent AD changes. A greater midfrontal, as opposed to hippocampal, cholinergic deficit may differentiate LBV from AD. The lack of a relationship between epsilon4 allele dosage and midfrontal ChAT activity suggests that other factors may play a role in its decline in LBV.

Effect of treatment for 6 months with human parathyroid hormone (1-34) peptide in ovariectomized cynomolgus monkeys (Macaca fascicularis).

A potential negative side effect of intermittent parathyroid hormone (PTH) therapy to treat osteoporosis is the loss of cortical bone concomitant with increased cancellous bone mass. We addressed this issue by studying the effects of PTH on whole-body, axial, and appendicular bone mass in an animal model with haversian cortical bone remodeling. Ovariectomized, young adult female cynomolgus monkeys were assigned to placebo (n = 9) or PTH groups (n = 10). The PTH group received 10 microg/kg synthetic human PTH(1-34) peptide by subcutaneous injection, 3 days/week for 6 months, and the placebo group received vehicle. Multiple endpoints of bone mass, strength, and turnover in the axial and appendicular skeleton were assessed, including dual-energy X-ray absorptiometry (DEXA), quantitative computed tomography (qCT), analysis of serum (calcium, phosphorus, alkaline phosphatase, osteocalcin, and tartrate-resistant acid phosphatase) and urinary (calcium and creatinine) biomarkers, histomorphometry, and biomechanical testing. Compared with placebo-treated animals, PTH-treated monkeys had no change in whole-body bone mass, but a 6.7% increase in spinal areal bone mineral density (aBMD) was observed. Cortical bone mass measured by qCT at appendicular sites was not affected by PTH treatment, but there were significant increases in cancellous bone mass in the proximal tibia, and a similar trend in the distal radius. Small, transient increases in serum and urinary calcium were observed, but there were no treatment-related effects on other biochemical endpoints. Increased bone formation rate (BFR/BV) in the midradius and midfemur was accompanied by a nonsignificant increase in midfemur porosity. Increased vertebral cancellous bone volume (BV/TV) was associated with greater trabecular and interstitial thickness with no effect on wall thickness. Increases in bone strength were observed in both axial (vertebral maximum stress and load at fracture) and appendicular (femoral neck fracture load) skeleton. Together, these results indicate that PTH therapy in the cynomolgus monkey results in a net gain of spinal and appendicular cancellous bone mass with no adverse effect on cortical bone.

Structure of the human CpG-island-containing lung Kruppel-like factor (LKLF) gene and its location in chromosome 19p13.11-13 locus.

We have cloned earlier a short human genomic fragment which showed strong similarity with the mouse cDNA encoding lung Kruppel-like zinc finger transcription factor (LKLF), predominantly expressed in mouse developing lung, spleen, and vascular system, which might play a key role in programming the quiescent state of single positive T cells and blood vessel wall morphogenesis. Here we report the successful cloning of the human LKLF cDNA, its genomic structure and chromosomal localization at the 19p13.11-p13.13 locus. The full-length human LKLF cDNA has longer 5'-UTR with higher GC content than mouse cDNA and encodes a predicted protein of 355 amino acids which has three zinc fingers at the C-terminus and a proline-rich N-terminal domain. Human and mouse proteins share 87.3% identity and 90.2% amino acid similarity. The human LKLF gene consists of three exons. From the proximal promoter to the end of the second exon, we have found a CpG island with an average 76% GC content and two regions of unusually high GC density.

Metaphors of mind and society. The origins of German psychiatry in the revolutionary era.

Johann Christian Reil's long polemic, Rhapsodieen über die Anwendung der psychischen Curmethode der Geisteszerrütungen (1803), is a call for the reform of the treatment of the insane. It also marks a transition from the Kantian approach to physiology of his earlier work to the Naturphilosophie that increasingly characterized his publications after this time. In this essay I first survey the historiographical debates of recent years concerning society and the emergence of psychiatry. I then examine the social-cultural context of the late Aufklärung in Prussia, out of which Reil's work emerged, before sketching the intellectual background of the Rhapsodieen, which lies in the development of German physiology since the 1750s. The heart of my work is a close analysis of Reil's theory of mental illness. Here I tease out his political and cultural imagery and note the ways in which his originally Enlightenment assumptions shifted toward the Romantic amid the anxieties of the revolutionary era.
