Ochronotic spondyloarthropathy: spinal involvement resembling ankylosing spondylitis.

Ochronotic spondyloarthropathy is a rare metabolic disease with the musculoskeletal manifestations of alkaptonuria. Ochronotic arthropathy patients may have spinal abnormalities similar to ankylosing spondylitis (AS). The proof of sacroiliac involvement or bamboo spine appearance is not sufficient either for diagnosis of ankylosing spondilitis or exclusion of ochronosis. In this report, the case of a 54-year-old woman having ochronosis, with clinically more recognizable axial arthropathy resembling AS, is presented, and the history, clinical presentation, diagnostic techniques, and distinctive diagnosis are reviewed.

Ankylosing spondylitis and undifferentiated spondyloarthritis in Kuwait: a comparison between Arabs and South Asians.

The objectives of this study were to describe and compare the clinical characteristics of ankylosing spondylitis (AS) and undifferentiated spondyloarthritis (USpA) in Middle East Arab (MEA) and South Asian (SA) patients diagnosed in our unit. Fifty-eight consecutive patients diagnosed with SpA were studied after classifying them into MEA and SA. They were further classified as per disease diagnosis. Excluding three patients with miscellaneous ethnicity, there were 29 MEA and 26 SA patients. Seventy-two percent of MEA patients were males (vs 92% of SA patients). Of the 29 patients with MEA ethnicity, 17 had AS and 9 had USpA. Of the 26 patients with SA ethnicity, 10 had AS and 14 had USpA. Fifty-nine percent of MEA patients had AS (vs 39% of SA patients). Mean age at onset in AS patients was similar in the two ethnic groups. However, in patients with USpA, mean age at onset was somewhat lower at 21.8 years in the MEA group compared with 29.4 years in the SA group. Family history in first-degree relatives was significantly more common in MEA patients. Weight loss, inflammatory spinal pain, gluteal pain, and enthesopathy were equally common in both ethnic groups. Knee, ankle, and metatarsophalangeal joint involvement was less common in MEA patients. There were no significant differences in the occurrence of syndesmophytes, bamboo spine, and sacroiliitis in the two ethnic groups. HLA-B27 positivity rates in MEA patients were 87% for AS and 67% for USpA compared to 75 and 71%, respectively, in SA patients. It is concluded that some significant new findings have arisen from this study: the majority of MEA patients presented with AS, whereas the majority of SA patients had a picture of USpA. Family history was more common in MEA patients. Peripheral arthritis was less common in MEA patients. Worldwide, this is the first study to show that there are significant differences in the clinical expression of the various SpA in MEA patients compared to SA patients.

Sleeping sites of Rhinopithecus bieti at Mt. Fuhe, Yunnan.

Data on sleeping site selection were collected for a group of black-and-white snub-nosed monkeys (Rhinopithecus bieti; around 80) at Mt. Fuhe, Yunnan, China (99 degrees 20'E, 26 degrees 25'N, about 3,000 m asl) from November 2000 to January 2002. At the site mainly three vegetation types were present in an elevation-ascending order: deciduous broad leaf forest, mixed coniferous and broad leaf forest, and dark coniferous forest. In addition, bamboo forest presented in areas burned in 1958. Sleeping sites (n =10) were located in the coniferous forest, where trees were the tallest, bottommost branches were the highest, the diameter of crowns was the second largest, and the gradient of the ground was the steepest. Monkeys usually kept quiet during entering and staying at a sleeping site. The site choice and the quietness may be tactics to avoid potential predators. In the coniferous forest, however, monkeys did not sleep in the valley bottom where trees were the largest, but frequently slept in the middle of the slope towards the east/southeast, in the shadow of ridges in three other directions, to avoid strong wind and to access sunshine; in winter-spring, they ranged in a more southern and lower area than in summer-autumn. These may be behavioral strategies to minimize energy stress in the cold habitat. Monkeys often slept in the same sleeping site on consecutive nights, which reflected a reduced pressure of predation probably due to either the effectiveness of anti-predation through sleeping site selection, or the population decline of predators with increasing human activities in the habitat. The group's behavioral responses to interactive and sometimes conflicting traits of the habitat are site-specific and conform to expectations for a temperate zone primate.

Orectolobicestus n. g. (Cestoda: Tetraphyllidea), with the description of five new species and the transfer of Phyllobothrium chiloscyllii to the new genus.

ORECTOLOBICESTUS N. G. (CESTODA: Tetraphyllidea) is erected for six cestode species parasitising bamboo sharks (Orectolobiformes: Chiloscyllium). Members of this genus differ from all other phyllobothriid genera in possessing modified maisiform spinitriches on their distal bothridial surfaces. In addition, they are easily recognised in that they share the following unique combination of characters: their vitelline fields are interrupted by the ovary, their necks are scutellate, and their bothridia bear an apical sucker and marginal loculi. Five new species of Orectolobicestus are described, including O. tyleri n. sp. from Chiloscyllium punctatum off Borneo, O. lorettae n. sp. from C. cf. punctatum off Australia, O. mukahensis n. sp. and O. kelleyae n. sp. from C. indicum off Borneo, and O. randyi n.sp. from C. hasselti also from off Borneo. In addition, Phyllobothrium chiloscyllii Subhapradha, 1955 is transferred to the new genus. O. chiloscyllii (Subhapradha, 1955) n. comb. is readily distinguished from all five new species in its greater total length. In addition to a number of proglottid features, O. kelleyae n. sp. and O. randyi n. sp. clearly differ from the other three new species in their possession of trifid, rather than fully serrate, spinitriches on their proximal bothridial surfaces. The latter two species conspicuously differ from one another in total number of proglottids (11-21 vs 27-38). O. tyleri n. sp. generally has fewer proglottids than O. lorrettae n. sp. (7-17 vs 13-23) and, like O. mukahensis n. sp., possesses scutes that are spathate rather than elongate. O. tyleri n. sp. is readily distinguished from O. mukahensis n. sp. in its possession of fewer proglottids (7-17 vs. 19-29). The five new species of Orectolobicestus share derived bothridial microthrix features with Phyllobothrium squali Yamaguti, 1952, Thysanocephalum sp., Orygmatobothrium sp., Ruhnkecestus Caira & Durkin, 2006 and species of Paraorygmatobothrium Ruhnke, 1994. Among these taxa, Orectolobicestus most closely resembles Paraorygmatobothrium and Ruhnkecestus in its vitelline fields being interrupted by the ovary and the possession of a scutellate neck.

Eating habits of east Asian people and transmission of taeniasis.

In order to understand the role of raw meat and viscera eating habits in the transmission of taeniasis in Asian countries, 1502 infected aborigines in ten mountainous districts/towns of six counties in Taiwan, 58 infected persons in two villages on Cheju Island, Korea, and 97 cases in Ambarita District on Samosir Island, North Sumatra, Indonesia were studied during the field surveys. All infected Taiwan aborigines had the habit of eating raw meat and viscera of wild and/or domestic animals. Among these aborigines, 73% ate wild boar, 66% flying squirrel, 65% wild goat, 56% muntjac, 49% wild rats, 46% monkey, 38% hare, 20% civet-cats, 18% weasel, 17% pheasant, 14% squirrel, 4% grouse, 1% deer, 1% snake, less than 1% bamboo partridge, less than 1% frog, less than 1% bear, less than 1% dog, and less than 1% fox. Of the 58 infected persons with Taenia on Cheju Island, Korea, 72% ate raw meat and/or viscera of pig and cattle, 19% raw pork only, and 9% raw beef only. Among 12 infected persons infected with T. saginata-like tapeworms, 7 had eaten raw pork, 2 raw beef and pork and 3 raw pork. Almost all of the 97 cases of taeniasis on Samosir Island of North Sumatra, Indonesia, had eaten only undercooked pork. Eleven of 15 cases were found to be infected with T. saginata-like tapeworms. Eating habits observed suggest an unusual way of transmission of Taenia in East Asia.

Vaccine-associated poliomyelitis in a household contact with Netherton's syndrome receiving long-term steroid therapy.

Paralytic poliomyelitis developed in a man 51 days after his two-month-old daughter received her first dose of trivalent live oral poliovirus vaccine. The patient was receiving long-term glucocorticosteroid therapy (tapered to 12.5 mg per day for the eight months prior to his poliomyelitis) for Netherton's syndrome, a congenital syndrome characterized by bamboo-like hair, hyperkeratotic and hyperhidrotic skin, and multiple allergies. The patient was ventilator-dependent and quadriplegic throughout most of his hospital stay and died in the hospital 10 months after the onset of paralysis. "Vaccine-like" type 3 poliovirus was isolated from a stool specimen and his serum showed a significant rise in neutralizing antibody titer against type 3 virus. This case report represents the first documented case of vaccine-associated poliomyelitis in a household contact receiving glucocorticosteroids, although evidence of immunosuppression was not documented. Nevertheless, the case reinforces current recommendations not to administer oral poliovirus vaccine to persons known to be immune deficient or suppressed or to normal persons with close contacts known to be immune deficient or suppressed.

Ankylosing spondylitis in nonhuman primates: the drill and the siamang.

Nonhuman primates are known to be susceptible to many of the arthritides that afflict humans. Psoriatic like spondyloarthropathies have been reported in gorillas and skeletal hyperostosis in gibbons, rhesus monkeys, and gorillas, and additional cases of both of these conditions occurring in drills (baboons) are noted in this report. One western lowland gorilla and two rhesus monkeys with clinical features consistent with ankylosing spondylitis have been documented previously. Two additional nonhuman primate species with radiographic evidence of ankylosing spondylitis are described. A siamang (gibbon) and two drills (baboons) with the classic radiographic features of ankylosing spondylitis, namely a bamboo spine and sacroiliac joint fusion, are reported.

Intestinal helminthiases in relation to the socioeconomic environment of Panamanian children.

A cross-sectional investigation was made into ascariasis and nutritional status in Panamanian preschool children from October 1983 to July 1984. Within this framework, an analysis was undertaken of possible relationships between a range of intestinal helminthiases and the socioeconomic status of the participants. Attention was paid to caregiver's education, parental occupation, family earnings, quality of housing and sanitation in the assessment of socioeconomic status. On this basis, strong associations were established between the socioeconomic status of the children and infection with Ascaris lumbricoides, Trichuris trichiura and hookworm. In general, the prevalence of single and multiple helminth infections was significantly higher in children living in housing made of wood or bamboo than in those living in housing made of concrete blocks. The same pattern applied to levels of sanitation. Ascaris lumbricoides occurred more frequently in children of mothers with the least formal education and in children living in relatively crowded conditions. Evidence was also obtained to indicate that the intensity of the intestinal helminth infections was greater in the children from the poorer environment. Since children from poorer socioeconomic conditions might be more exposed to infective stages than those from a better environment, the possible role of socioeconomic factors in contributing to the predisposition of some individuals to harbour large worm burdens of intestinal helminths was briefly discussed.

Rupture of the flexor digitorum profundus tendon in the palm caused by repeated, chronic direct trauma.

Nonrheumatoid ruptures of the flexor tendons in the palm are rare. We report a case in which excessive exertion caused rupture of the flexor digitorum profundus tendon to the small finger in the palm at the level of the lumbrical origin. The patient had been practicing Japanese fencing for many years. The hard butt end of a bamboo sword impinged precisely on the region in the palm where the rupture occurred.

An animal model for the assessment of gingival lesions.

A model of gingival inflammation was performed in Sprague-Dawley rats weighing 180-200 g. Mechanical bamboo stick-induced injury was inflammatory when bacteria contaminated the sticks. Bacteria were first obtained from gingival fluid collected from a patient with adult periodontitis. Another strain from Institut Pasteur (IP 6444) induced similar inflammation. Inflammation was then quantified 10 days later by means of elastase assays performed in gingival extracts. In parallel, elastic structures were observed and elastic fibers were quantified by automated image analysis. This technique of "impaction" was able to induce a gingival inflammatory reaction characterized by a significant increase of gingival elastase content, infiltration of gingival tissues by elicited cells, and gingival elastic fiber breakdown. These parameters were correlated, and measurement of one of them might be useful for pharmacological studies applied to the treatment of periodontal lesions. An example of results obtained from animals treated by heparine was shown.

Liquid filled nanoparticles as a drug delivery tool for protein therapeutics.

In the present study, an attempt was made to study the feasibility of nanoparticulate adsorbents in the presence of an absorption enhancer, as a drug delivery tool for the administration of erythropoietin (EPO) to the small intestine. Liquid filled nano- and micro-particles (LFNPS/LFMPS) were prepared using solid adsorbents such as porous silicon dioxide (Sylysia 550), carbon nanotubes (CNTs), carbon nanohorns, fullerene, charcoal and bamboo charcoal. Surfactants such as a saturated polyglycolysed C8-C18 glyceride (Gelucire 44/14), PEG-8 capryl/caprylic acid glycerides (Labrasol) and polyoxyethylene hydrogenated castor oil derivative (HCO-60) were used as an absorption enhancer at 50mg/kg along with casein/lactoferrin as enzyme inhibitors. The absorption of EPO was studied by measuring serum EPO levels by an ELISA method after small intestinal administration of EPO-LFNPS preparation to rats at the EPO dose level of 100 IU/kg. Among the adsorbents studied, CNTs showed the highest serum EPO level of 62.7 +/- 11.6 mIU/ml. In addition, with the use of casein, EPO absorption was improved, C(max) 143.1 +/- 15.2 mIU/ml. Labrasol showed the highest absorption enhancing effect after intra-jejunum administration than Gelucire 44/14 and HCO-60, 25.6 +/- 3.2 and 22.2 +/- 3.6 mIU/ml, respectively. Jejunum was found to be the best absorption site for the absorption of EPO from LFNPS. The use of CNTs as LFNPS, improved the bioavailability of EPO to 11.5% following intra-small intestinal administration.

Metagenomic insights into the mechanisms of heteroatom-doped, iron-loaded biochar in enhancing anaerobic digestion of waste activated sludge.

Anaerobic digestion is a crucial technology for resource recovery from waste activated sludge. Enhancing its methane production efficiency using conductive materials is a key research objective. This study aimed to elucidate the mechanisms by which conductive materials promote this process. Three types of biochar(FeS@BC300, FeP@BC600, and FeP@BC900) were prepared by doping bamboo powder with N, P, S and iron salts under pyrolysis conditions at 300-900 °C, and their physical and chemical properties were characterized, including surface functional groups, specific surface area, capacitance, electrical resistance, electron-accepting capacity (EAC), and electron-donating capacity (EDC). These analyses assessed the influence of synthesis parameters. These materials were subsequently introduced into the anaerobic digestion of thermally hydrolyzed sludge to evaluate their impacts on methanogenic performance, microbial community structure, and metabolic pathways. The results show that the FeP@BC600 material, which exhibited the highest EDC, substantially increased microbial cytochrome c production (by 29.2 % compared to the control). This enhancement improved interspecies electron transfer, stimulated ATP synthesis (increased by 41.5 %), and reinforced both hydrogenotrophic and acetoclastic methanogenic pathways, ultimately elevating methane production by 55 %. Integrated analysis of metagenomic data, material properties, and performance metrics revealed that the key mechanism by which FeP@BC600 promotes methanogenesis is through the enrichment of cytochrome c-encoding genes, thereby facilitating direct interspecies electron transfer (DIET) and augmenting ATP synthesis. This study provides a foundation for the subsequent application of conductive materials to enhance anaerobic digestion and offers guidance for the optimized design of such materials.

Evolutionary aspects of intestinal bicarbonate secretion in fish.

Experiments compared intestinal HCO3- secretion in the intestine of marine teleost Gulf toadfish, Opsanus beta, to representatives of early chondrostean and chondrichthyan fishes, the Siberian sturgeon, Acipenser baerii, and white-spotted bamboo shark, Chiloscyllium plagiosum, respectively. As seen in marine teleosts, luminal HCO3- concentrations were 10-fold plasma levels in all species when exposed to hyperosmotic conditions. While intestinal water absorption left Mg2+ and SO4(2-) concentrated in intestinal fluids up to four-fold ambient seawater concentrations, HCO3- was concentrated up to 50 times ambient levels as a result of intestinal HCO3- secretion. Reduced luminal Cl- concentrations in the intestine of all species suggest that HCO3- secretion also occurs via Cl-/HCO3- exchange in chondrostean and chondrichthyan fishes. Sturgeon began precipitating carbonates from the gut after only 3 days at 14 per thousand, a mechanism utilized by marine teleosts to reduce intestinal fluid osmolality and maintain calcium homeostasis. Analysis of published intestinal fluid composition in the cyclostome Lampetra fluviatilis reveals that this species likely also utilize intestinal HCO3- secretion for osmoregulation. Analysis of existing cyclostome data and our results indicate that intestinal Cl-/HCO3- exchange plays an integral role in maintaining hydromineral balance not only in teleosts, but in all fish (and perhaps other animals) with a need to drink seawater.

Body fluid volume regulation in elasmobranch fish.

This review addresses an often overlooked aspect of elasmobranch osmoregulation, i.e., control of body fluid volume. More specifically the review addresses the impact of changes in blood volume in elasmobranchs exposed to different environmental salinities. Measurement of blood volume in the European lesser-spotted dogfish, Scyliorhinus canicula, following acute and chronic exposure to 80% and 120% seawater (SW) is reported. In 80%, 100% and 120% SW-adapted S. canicula, blood volume was 6.3+/-0.2, 5.6+/-0.2 and 4.6+/-0.2 mL 100 g(-1) body mass, respectively. Blood volume was significantly higher and lower in 80% and 120% SW-acclimated animals compared to 100% SW controls. Comparisons are made between these results and previously published data. The role of drinking and volume regulation in elasmobranchs is discussed. For the first time measured water reabsorption rates and solute flux rates across the elasmobranch intestinal epithelia are presented. Water reabsorption rates did not differ between 100% SW-adapted bamboo shark, Chiloscyllium plagiosum, and fish acutely transferred to 140% SW. For the most part net solute flux rates and direction for both the 100% and 140% SW groups were the same with the exception of a net efflux of chloride and potassium in the 140% group and influx of these ions in the 100% adapted group. The significance of the intestine as part of the overall elasmobranch osmoregulatory strategy is discussed as is the role of the kidneys, rectal gland and gills in the regulation of body fluid volume in this class of vertebrates.

Determination of pesticides in compost by pressurized liquid extraction and gas chromatography-mass spectrometry.

A gas chromatographic-mass spectrometric method was developed for the determination of pesticides in compost. The investigated pesticides included two fungicides, two herbicides and 10 insecticides. The pesticides were extracted from the compost by pressurized liquid extraction. The extract was cleaned up by a partition between hexane and acetonitrile followed by a dispersive solid-phase extraction using a porous carbon made from Moso bamboo (Phyllostachys pubescens). The overall recoveries were 81-104% and the relative standard deviations (RSDs) ranged from 2.4 to 12%. The minimum detectable concentrations were 0.02-0.04 microg g(-1). This method was successfully applied to a compost sample from food waste as well as commercial compost.

Cytoprotective effects of heme oxygenase-1 induction by 3-O-caffeoyl-1-methylquinic acid.

The novel antioxidant 3-O-caffeoyl-one-methylquinic acid (MCGA3) is a methyl chlorogenic acid derivative isolated from bamboo leaves. MCGA3 scavenges reactive oxygen species (ROS) and inhibits lipid peroxidation and xanthine oxidase in vitro. In this study, we evaluated the cytoprotective effect of MCGA3, which occurs via heme oxygenase-1 (HO-1) induction in bovine vascular endothelial cells exposed to tert-butylhydroperoxide (tBHP). Cells treated with 1 mM tBHP (6-18 h) generated substantial ROS and concomitantly lost most intracellular lactate dehydrogenase (LDH), which then caused necrotic cell death. Of the several MCGA antioxidants and structurally related phenolic acids examined in this study, MCGA3 (0.01-0.15 mM) was found to completely block this necrosis and generation of ROS by tBHP. Surprisingly, MCGA3 by itself was found to be a potent inducer of HO-1. We observed the time- and dose-dependent induction of HO-1 mRNA and protein, which was closely associated with decreased intracellular ROS and necrosis against tBHP. Deesterified or Al-chelated MCGA3 or co-treatment with MCGA3 and actinomycin D abolished HO-1 induction and the antinecrotic effect of MCGA3. Zinc protoporphyrin IX and cycloheximide attenuated the cytoprotection afforded by MCGA3, but did not reduce HO-1 mRNA. Interestingly, N-acetylcysteine (1 mM) enhanced the HO-1 induction of MCGA3, but N-acetylcysteine itself did not induce HO-1. These results suggested that not only ortho-dihydroxyl groups but also aromatic ester and methoxyl ester moieties are necessary for full HO-1 induction and cytoprotection against toxic tBHP-derived ROS. Ferritin mRNA was also upregulated during all HO-1 induction by MCGA3, which might decrease iron and lower ROS levels. Consequently, the combined action of HO-1 and ferritin may protect cells from toxic tBHP-mediated necrosis.

The novel antioxidant 3-O-caffeoyl-1-methylquinic acid induces Nrf2-dependent phase II detoxifying genes and alters intracellular glutathione redox.

Induction of detoxifying phase II genes by chemopreventive agents represents a coordinated protective response against oxidative stress and neoplastic effects of carcinogens. We have earlier shown that a novel antioxidant from the bamboo leaves constituent 3-O-caffeoyl-1-methylquinic acid (MCGA3) induces heme oxygenase-1 (HO-1) and protects endothelial cells from ROS-induced endothelial injury. The purpose of this study was to elucidate the induction mechanism of HO-1 and other phase II genes by MCGA3 in human umbilical vascular endothelial cells (HUVECs). Using Northern blotting and RT-PCR, we found that treatment of HUVECs with MCGA3 increased, in a dose and time-dependent manner, steady-state mRNA levels of the selected phase II genes including HO-1, ferritin, gamma-glutamylcysteine lygase, glutathione reductase, and glutathione transferase, which were dependent on Nrf2 nuclear translocation. The observed phase II gene induction by MCGA3 was found to be associated with MCGA3-mediated cytoprotective activity, ROS-scavenging potency, and the increase in the cellular levels of both reduced (GSH) and oxidized glutathione (GSSG). Interestingly, exposure to MCGA3 resulted in a decreased ratio of GSH/GSSG, which was negatively related with mRNA level of phase II genes. By employing N-acetylcysteine and GSH biosynthetic enzyme inhibitors as well as prooxidants, hemin and H(2)O(2), we show that a decreased intracellular GSH/GSSG homeostasis, at least in part, may be involved in the MCGA3-mediated phase II gene induction and Nrf2 translocation, although the attenuation of HO-1 expression with SP 600125 supports a partial involvement of JNK signaling.

Immunomodulation by Dok Din Daeng (Aeginetia indica Roxb.) extracts in female B6C3F1 mice: (I): stimulation of T cells.

Aeginetia indica Roxbert (Dok Din Daeng, DDD), a parasitic plant that grows on bamboo, is extensively used in Thai traditional medicine to treat various diseases. There have been no published studies on the pharmacological, toxicological or immunological effects of DDD, indigenous to Thailand. The study reported here was focused on the immunological effects (T cells) of the whole plant extract using water (WDDD) or ethanol (EDDD) as a solvent. The extracts were administered to female B6C3F1 mice by gavage for WDDD (10-100%) and intraperitoneally (i.p.) for EDDD (0.25-250 mg/kg) for 28 days. Only mice administrated the highest dose of EDDD exhibited an increase in absolute spleen and liver weights. Three T cell functional assays, including anti-CD3 antibody-mediated T cell proliferation, the mixed leukocyte response (MLR) and the cytotoxic T lymphocyte (CTL) response, were employed to determine the effects of DDD extracts on splenic T cell activities. Exposure to WDDD enhanced the responses in all three assays with significant changes observed in the anti-CD3 and MLR assays. Exposure to EDDD also enhanced the responses in all three assays with significant changes observed in the MLR and CTL assays. Additionally, significant increases in the MLR and anti-CD3 responses were also observed when EDDD was used to treat cells in vitro. Finally, exposure to WDDD decreased both the percentage and absolute number of regulatory CD4(+)CD25(+) T cells in the spleen, which was consistent with a significant increase in interferon-gamma (IFN-gamma) production from Con A-stimulated splenocytes. Overall, this study demonstrated that the extracts from A. indica Roxbert had a T cell stimulatory activity.
