    Chen, Yu-Fen; Lu, Wen-Ling; Wu, Ming-Der; Yuan, Gwo-Fang


    "Niu-Chang-Chih" (Antrodia cinnanomea) is a medicinal mushroom that has only been collected from the aromatic tree, Cinnamomum kanehirai, which is native to Taiwan. A total of 105 Taiwan patent applications and patents for "Niu-Chang-Chih" were collected and analyzed. Patent applications and granted patents claiming newly identified functional components from "Niu-Chang-Chih," biologically pure cultures of the mushroom strain, and cultivation of "Niu-Chang-Chih" were examined. Several applications and patents claim identified active compounds from "Niu-Chang- Chih," which provide better patent protection. These newly identified functional compounds include cyclohexanones, maleic and succinic acid derivatives, labdane diterpenoids, and benzenoids. Newly identified functional proteins include a glutathione-dependent formaldehyde dehydrogenase (GFD), a glycoprotein named ACA1, and a laccase. Newly identified functional polysaccharides include ACP1, ACP2, and ACP3. The number of patents for newly identified compounds and their uses are expected to continue growing.

  2. Origin of the mysterious Yin-Shang bronzes in China indicated by lead isotopes. (United States)

    Sun, Wei-dong; Zhang, Li-peng; Guo, Jia; Li, Cong-ying; Jiang, Yu-hang; Zartman, Robert E; Zhang, Zhao-feng


    Fine Yin-Shang bronzes containing lead with puzzlingly highly radiogenic isotopic compositions appeared suddenly in the alluvial plain of the Yellow River around 1400 BC. The Tongkuangyu copper deposit in central China is known to have lead isotopic compositions even more radiogenic and scattered than those of the Yin-Shang bronzes. Most of the Yin-Shang bronzes are tin-copper alloys with high lead contents. The low lead and tin concentrations, together with the less radiogenic lead isotopes of bronzes in an ancient smelting site nearby, however, exclude Tongkuangyu as the sole supplier of the Yin-Shang bronzes. Interestingly, tin ingots/prills and bronzes found in Africa also have highly radiogenic lead isotopes, but it remains mysterious as to how such African bronzes may have been transported to China. Nevertheless, these African bronzes are the only bronzes outside China so far reported that have lead isotopes similar to those of the Yin-Shang bronzes. All these radiogenic lead isotopes plot along ~2.0-2.5 Ga isochron lines, implying that deposits around Archean cratons are the most likely candidates for the sources. African cratons along the Nile and even micro-cratons in the Sahara desert may have similar lead signatures. These places were probably accessible by ancient civilizations, and thus are the most favorable suppliers of the bronzes.

    The possibility and problems of using radiocarbon dating to historical chronology are discussed. The current situation of ancient Chinese chronology and the project of Xia-Shang-Zhou chronology are introduced. A chronological study requires the AMS radiocarbon dating with high precision, high reliability and high efficiency. The Peking University AMS facility (PKUAMS) has been upgraded and a series of quality control steps were adopted. To reduce the error of calendar age, wiggle matching with serial samples should be used. Some preliminary results of Xia-Shang-Zhou chronology are presented.

    Lin, Hsiao-Man; Lu, Fang-Chuan; Tsai, J. C.


    Utilization of the developed digital archives could stimulate the spirit of humanity and creativity, especially for Chinese people in Taiwan, and also satisfy cultural passion and pursuit of knowledge. Furthermore, this study creates simulated informational digital archives of Tainan Chih-Kan-Tower in order to effectively integrate the multiple unique and useful historical records and information. Examples include Chih-Kan- Tower's historical change and Taiwan's ancient map. The study also creates a three dimension (3D) visualization and a two dimension (2D) motion video which, provided by Google Earth, can enhance the experience of media interaction, improve cultural interaction as well as multi-level knowledge by better understanding . With further research on application of digital archives in multiple facets, the finally developed digital archives have great potential to become a very useful tool to promote the most valuable cultural heritage in the nation.

  5. [Shang Ring circumcision versus conventional circumcision for redundant prepuce or phimosis: a meta analysis]. (United States)

    Xiao, Er-Long; Ding, Hui; Li, Yong-Qian; Wang, Zhi-Ping


    To compare the effect and safety of Shang Ring circumcision with those of conventional circumcision in the treatment of redundant prepuce or phimosis. We retrieved the randomized controlled trials on Shang Ring circumcision and conventional circumcision for the treatment of redundant prepuce or phimosis published at home and abroad. Relevant data were selected according to the Cochrane Handbook for Systematic Reviews by two reviewers after quality evaluation of the included trials, and the statistical software RevMan 5.0 was used for meta analysis. Totally 8 randomized controlled trials with 2277 cases were included in this study. Compared with conventional circumcision, Shang Ring circumcision showed a shorter operation time (SMD = -5.82, 95% CI [ -7.39, -4.24], PSMD = -3.28, 95% CI [ -3.47, -3.09], Pinfection (OR = 0.44, 95% CI [0.26, 0.72], P=0.001), lower rate of postoperative bleeding (OR =0.05, 95% CI [0.02, 0.12], PSMD = -3.32, 95% CI [ -3.50, -3.14], PSMD = -3.28, 95% CI [ - 3.47, - 3.00], P<0.00001), but longer wound healing time (OR=1.46, 95% CI [1.03, 1.90], P<0.00001). In comparison with conventional circumcision, Shang Ring circumcision has the advantages of shorter operation time, fewer complications, mild pain, and higher rate of satisfaction with the postoperative penile appearance. However, more high-quality randomized controlled trials with large samples are required to lend further support to our findings.

  8. The viper fangs: clinical anatomy, principles of physical examination and therapy (a review

    Directory of Open Access Journals (Sweden)

    Matteo Oliveri


    Full Text Available The assessment of fangs is a fundamental part of clinical examination of viperid snakes. The long curved venom fang is carried by short, highly mobile maxilla. Short anaesthesia is advised for safe physical examination and radiography of the mouth cavity. The fangs are gently forced outside the fang pocket by passing the bar or forceps on the palato-maxillary arch, and rotating them rostrally shifting the mucosal fold. Functional fangs are periodically shed and several generations of replacement teeth lie behind and beneath each fang. In case of fang fracture, therapy should be limited to flushing with a solution of chlorhexidine or povidone iodine, and topical application of pro-coagulant and antibacterial cream. Therapy of chronic fang inflammation is based on removal of necrotized fang and repeated abundant irrigation of the fang pocket. Treatment of chronic stomatitis consists of flushing with chlorhexidine or povidone iodine, physical removal of the plaques, administration of analgesics and antibiotics (marbofloxacin, enrofloxacin or ceftazidime. Extra-oral surgical approach is the best method for odontogenic abscess removal. A vigorous flushing with sterile saline solution, chlorhexidine and povidone iodine and topical application of antibiotics (antibiotic embedded surgical sponge is advised. Force feeding of the anorectic patient suffering from fang inflammation is a mandatory part of the standard treatment protocol.

  9. Has snake fang evolution lost its bite? New insights from a structural mechanics viewpoint. (United States)

    Broeckhoven, Chris; du Plessis, Anton


    Venomous snakes-the pinnacle of snake evolution-are characterized by their possession of venom-conducting fangs ranging from grooved phenotypes characterizing multiple lineages of rear-fanged taxa to tubular phenotypes present in elapids, viperids and atractaspidines. Despite extensive research, controversy still exists on the selective pressures involved in fang phenotype diversification. Here, we test the hypothesis that larger fangs and consequently a shift to an anterior position in the maxilla evolved to compensate for the costs of structural changes, i.e. higher stress upon impact in tubular fangs compared to grooved fangs. Direct voxel-based stress simulations conducted on high-resolution µCT scans, analysed within a phylogenetic framework, showed no differences in stress distribution between the three fang phenotypes, despite differences in (relative) fang length. These findings suggest that additional compensatory mechanisms are responsible for the biomechanical optimization and that fang length might instead be related to differential striking behaviour strategies. © 2017 The Author(s).

  12. Viperous fangs: development and evolution of the venom canal. (United States)

    Zahradnicek, Oldrich; Horacek, Ivan; Tucker, Abigail S


    Fangs are specialised long teeth that contain either a superficial groove (Gila monster, Beaded lizard, some colubrid snakes), along which the venom runs, or an enclosed canal (viperid, elapid and atractaspid), down which the venom flows inside the tooth. The fangs of viperid snakes are the most effective venom-delivery structures among vertebrates and have been the focus of scientific interests for more than 200 years. Despite this interest the questions of how the canal at the centre of the fang forms remains unresolved. Two different hypotheses have been suggested. The mainstream hypothesis claims that the venom-conducting canal develops by the invagination of the epithelial wall of the developing tooth germ. The sides of this invagination make contact and finally fuse to form the enclosed canal. The second hypothesis, known as the "brick chimney", claims the venom-conducting canal develops directly by successive dentine deposition as the tooth develops. The fang is thus built up from the tip to the base, without any folding of the tooth surface. In an attempt to cast further light on this subject the early development of the fangs was followed in a pit viper, Trimeresurus albolabris, using the expression of Sonic hedgehog (Shh). We demonstrate that the canal is indeed formed by an early folding event, resulting from an invagination of epithelial cells into the dental mesenchyme. The epithelial cells proliferate to enlarge the canal and then the cells die by apoptosis, forming an empty tube through which the poison runs. The entrance and discharge orifices at either end of the canal develop by a similar invagination but the initial width of the invagination is very different from that in the middle of the tooth, and is associated with higher proliferation. The two sides of the invaginating epithelium never come into contact, leaving the orifice open. The mechanism by which the orifices form can be likened to that observed in reptiles with an open groove along

  13. Understanding Biological Roles of Venoms Among the Caenophidia: The Importance of Rear-Fanged Snakes. (United States)

    Mackessy, Stephen P; Saviola, Anthony J


    Snake venoms represent an adaptive trophic response to the challenges confronting a limbless predator for overcoming combative prey, and this chemical means of subduing prey shows several dominant phenotypes. Many front-fanged snakes, particularly vipers, feed on various vertebrate and invertebrate prey species, and some of their venom components (e.g., metalloproteinases, cobratoxin) appear to have been selected for "broad-brush" incapacitation of different prey taxa. Using proteomic and genomic techniques, the compositional diversity of front-fanged snakes is becoming well characterized; however, this is not the case for most rear-fanged colubroid snakes. Because these species consume a high diversity of prey, and because venoms are primarily a trophic adaptation, important clues for understanding specific selective pressures favoring venom component composition will be found among rear-fanged snake venoms. Rear-fanged snakes typically (but not always) produce venoms with lower complexity than front-fanged snakes, and there are even fewer dominant (and, arguably, biologically most relevant) venom protein families. We have demonstrated taxon-specific toxic effects, where lizards and birds show high susceptibility while mammals are largely unaffected, for both Old World and New World rear-fanged snakes, strongly indicating a causal link between toxin evolution and prey preference. New data are presented on myotoxin a, showing that the extremely rapid paralysis induced by this rattlesnake toxin is specific for rodents, and that myotoxin a is ineffectual against lizards. Relatively few rear-fanged snake venoms have been characterized, and basic natural history data are largely lacking, but directed sampling of specialized species indicates that novel compounds are likely among these specialists, particularly among those species feeding on invertebrate prey such as scorpions and centipedes. Because many of the more than 2200 species of colubroid snakes are rear-fanged

  15. Osteoarchaeological Studies of Human Systemic Stress of Early Urbanization in Late Shang at Anyang, China (United States)

    Zhang, Hua; Merrett, Deborah C.; Jing, Zhichun; Tang, Jigen; He, Yuling; Yue, Hongbin; Yue, Zhanwei; Yang, Dongya Y.


    Through the analysis of human skeletal remains and mortuary practice in Yinxu, this study investigates the impact of early urbanization on the commoners during the Late Shang dynasty (ca. 1250–1046 B.C.). A total of 347 individuals examined in this study represent non-elites who were recovered from two different burial contexts (formally buried in lineage cemeteries and randomly scattered in refuse pits). Frequencies of enamel hypoplasia (childhood stress), cribra orbitalia (childhood stress and frailty) and osteoperiostitis (adult stress) were examined to assess systemic stress exposure. Our results reveal that there was no significant difference in the frequency of enamel hypoplasia between two burial groups and between sexes, suggesting these urban commoners experienced similar stresses during childhood, but significantly elevated levels of cribra orbitalia and osteoperiostitis were observed in the refuse pit female cohort. Theoretically, urbanization would have resulted in increased population density in the urban centre, declining sanitary conditions, and increased risk of resource shortage. Biologically, children would be more vulnerable to such physiological disturbance; as a result, high percentages of enamel hypoplasia (80.9% overall) and cribra orbitalia (30.3% overall) are observed in Yin commoners. Adults continued to suffer from stress, resulting in high frequencies of osteoperiostitis (40.0% total adults); in particular, in the refuse pit females who may also reflect a compound impact of gender inequality. Our data show that the non-elite urban population in the capital city of Late Shang Dynasty had experienced extensive stress exposure due to early urbanization with further social stratification only worsening the situation, and eventually contributing to collapse of the Shang Dynasty.

    Dehghani R.1 PhD,


    Full Text Available Aims Venomous snake bites are public health problems in different parts of the world. The most specific mainstay in the treatment of envenomation is anti-venom. To treat the envenomation, it is very important to identify the offending species. This study was designed to determine the penetrating pattern of fangs and teeth of some viper snakes. Materials & Methods This descriptive study was performed on live venomous and nonvenomous snakes from 2010 till 2011. All 47 sample snakes were collected from different regions of Isfahan province such as Kashan City, Ghamsar, Niasar, Mashhad Ardehal, Taher- Abad and Khozagh. Their mouths were inspected every two weeks and development of their fangs and teeth were recorded by taking clear digital photos. Fangs and teeth patterns of samples were drawn and the results were compared. Findings One or two wounds appeared as typical fang marks at the bite site of venomous snakes while non-venomous snakes had two carved rows of small teeth. Three different teeth and fang patterns were recognized in venomous snakes which were completely different. Conclusion The fang marks of venomous snakes do not always have a common and classic pattern and there are at least 3 different patterns in Isfahan province, Iran.

    Trigerninal neuralgia is a common refractory disease in clinic. Professor FANG Jianqiao has rich experience through diagnosing and treating the disease for many years. In the first diagnosis, professor FANG underlines the position of damaged neuron and syndrome differentiation. He considers acupuncture should be implemented by stages,namely according to whether the patients are in the period of pain attack, different acupuocture prescriptions are made. Acupuncture manipulation and needle-retention time should be adjusted according to the condition of disease. And the appropriate application of electroacupuncture and transcutaneous electrical acupoint stimulation can strengthen the effect.

    Directory of Open Access Journals (Sweden)

    Hua Zhang

    Full Text Available This research investigates the prevalence of human osteoarthritis at Yinxu, the last capital of the Late Shang dynasty (ca. 1250-1046 B.C., to gain insights about lifeways of early urban populations in ancient China. A total of 167 skeletal remains from two sites (Xiaomintun and Xin'anzhuang were analyzed to examine osteoarthritis at eight appendicular joints and through three spinal osseous indicators. High osteoarthritis frequencies were found in the remains with males showing significantly higher osteoarthritis on the upper body (compared to that of the females. This distinctive pattern becomes more obvious for males from Xiaomintun. Furthermore, Xiaomintun people showed significantly higher osteoarthritis in both sexes than those from Xin'anzhuang. Higher upper body osteoarthritis is speculated to be caused by repetitive lifting and carrying heavy-weight objects, disproportionately adding more stress and thus more osseous changes to the upper than the lower body. Such lifting-carrying could be derived from intensified physical activities in general and specialized occupations in particular. Higher osteoarthritis in males may reveal a gendered division of labour, with higher osteoarthritis in Xiaomintun strongly indicating an occupational difference between the two sites. The latter speculation can be supported by the recovery of substantially more bronze-casting artifacts in Xiaomintun. It is also intriguing that relatively higher osteoarthritis was noticed in Xiaomintun females, which seems to suggest that those women might have also participated in bronze-casting activities as a "family business." Such a family-involved occupation, if it existed, may have contributed to establishment of occupation-oriented neighborhoods as proposed by many Shang archaeologists.

    Full Text Available In this inaugural address, delivered on the acceptance of an extraordinary professorship at Tilburg University, Netherlands, in 2011, Wilfried van Damme examines three approaches that have been characteristically applied within the Western anthropology of art during the last half century. Illustrating these approaches with reference to the study of Fang statuary from equatorial Africa, he discusses a stylistic approach, focusing on anatomical details and proportions of Fang anthropomorphic sculptures; a culturalist approach, highlighting the local meaning and values these sculptures express; and a postcolonial approach, dealing with the Western appropriation and commodification of Fang statues.

  6. Shingles Immunity and Health Functioning in the Elderly: Tai Chi Chih as a Behavioral Treatment

    Directory of Open Access Journals (Sweden)

    Michael Irwin


    Full Text Available Both the incidence and severity of herpes zoster (HZ or shingles increase markedly with increasing age in association with a decline in varicella zoster virus (VZV-specific immunity. Considerable evidence shows that behavioral stressors, prevalent in older adults, correlate with impairments of cellular immunity. Moreover, the presence of depressive symptoms in older adults is associated with declines in VZV-responder cell frequency (VZV-RCF, an immunological marker of shingles risk. In this review, we discuss recent findings that administration of a relaxation response-based intervention, tai chi chih (TCC, results in improvements in health functioning and immunity to VZV in older adults as compared with a control group. TCC is a slow moving meditation consisting of 20 separate standardized movements which can be readily used in elderly and medically compromised individuals. TCC offers standardized training and practice schedules, lending an important advantage over prior relaxation response-based therapies. Focus on older adults at increased risk for HZ and assay of VZV-specific immunity have implications for understanding the impact of behavioral factors and a behavioral intervention on a clinically relevant end-point and on the response of the immune system to infectious pathogens.

Emphases are put on the qi regulation function, needling sensation to the affected region and insertion with both hands, especially the function of the left hand as pressing hand. The gentle and superficial insertion should be done as the follows: hold the needle with the right hand, press gently along the running course of meridians with the left hand to promote qi circulation, hard pressing should be applied at acupoints to disperse the local qi and blood, insert the needle gently and quickly into the subcutaneous region with the right hand, and stop the insertion when patient has the needling sensation. While the fast needling is characterized with shallow insertion and swift manipulation: the left hand of the manipulator should press first along the running course of the meridian, and fix the local skin, hold the needle with the right hand and insert the needle quickly into the acupoint. Withdrawal of the needle should be done immediately after the reinforcing and reducing manipulations. Professor LI is accomplished in qi regulation. It is held by him that regulating qi circulation is essence of acupuncture, letting the patient get the needling sensation is the most important task of needling. Lifting, thrusting and rotation manipulations should be applied to do reinforcing or reducing. The tissue around the tip of the needle should not be too contracted or too relaxed, and the resistance should not be too strong or too weak. The feeling of the insertion hand of the practitioner should not be too smooth or too hesitant. Needle should be inserted into the skin quickly at the moment of hard pressing by the left hand. And then, slow rotation and gentle lifting and thrusting can be applied to promote the needling sensation like electric current pass through and to reach the affected region along the

    The Brown Treesnake (Boiga irregularis) is an arboreal, nocturnal, rear-fanged venomous snake native to northern and eastern regions of Australia, Papua New Guinea and the Solomon Islands. It was inadvertently introduced onto the island of Guam during the late 1940's to early 1950's, and it has caused massive declines and extirpations of the native bird, lizard, and mammal populations. In the current study, we report the characterization of the venom proteome of an adult and a neonate B. irregularis specimens from Guam by a combination of venom gland transcriptomic and venomic analyses. Venom gland transcriptomic analysis of an adult individual identified toxins belonging to 18 protein families, with three-finger toxin isoforms being the most abundantly expressed transcripts, comprising 94% of all venom protein transcript reads. Transcripts for PIII-metalloproteinases, C-type lectins, cysteine-rich secretory proteins, acetylcholinesterases, natriuretic peptides, ficolins, phospholipase A 2 (PLA 2 ) inhibitors, PLA 2 s, vascular endothelial growth factors, Kunitz-type protease inhibitors, cystatins, phospholipase Bs, cobra venom factors, waprins, SVMP inhibitors, matrix metalloproteinases, and hyaluronidases were also identified, albeit, at very low abundances ranging from 0.05% to 1.7% of the transcriptome. The venom proteomes of neonate and adult B. irregularis were also both overwhelmingly (78 and 84%, respectively) dominated by monomeric and dimeric 3FTxs, followed by moderately abundant (21% (N) and 13% (A)) CRISPs, low abundance (1% (N), 3% (A)) PIII-SVMPs, and very low abundance (blot analysis showed that all venom proteins were recognized by anti-BTS IgGs, and cross-reactivity with other rear-fanged snake venoms was also observed. Incubation of anti-BTS venom IgGs with crude B. irregularis venom resulted in a significant decrease in proteolytic (SVMP) activity against azocasein. These results provide the first comparative venomic and anti-venomic analysis of

    Xiu zhen fang (Pocket Formulary) is a recipe book of the Ming Dynasty, inspired and managed by Zhu Su, compiled by Li Heng of liangyisuo (good physician house) in Zhou wangfu (Zhou's royal palace). The book was compiled and published twice during the reigns of the Hongwu and Yongle Emperors of the Ming Dynasty. Because of its high practicability, there were some editions in circulation, and the book was published several times only in the Ming Dynasty. At present, the earliest extanteditionwas the little character version of Yongle, and the version in the 4(th) year of Zhengde Emperor of the Ming Dynasty was a reprinting edition based on the Yongle edition, sharingthe same edition system. Most of the editions appeared after the reign of Zhengtong Emperor of the Ming Dynasty, titled by "kui ben (head version)" and "da quan (complete edition)" were the editionspublished in the local bookshops, which had rather distinct differences from the Yongle edition system not only in the its format but also in its contents.

    This paper argues that the Erligang Culture was a mixture of the Erlitou-type Culture, the Zhanghe - type Culture and the special Erligang features. The Erliang Culture was a development of the Pre - Shang Culture and the Pre - Shang Culture and the Lower Erligang Culture represented the same Shang culture before and after the collapse of the Xia Dynasty and they had little difference in nature. It further argues that the formation of the Erligang culture began in Shangqiu district, thus Shangqiu remains and important area in exploring thePre - Shang Culture

    In this paper, a kind of specific stalactitic product was found on the interior surface of a covered bronze wine vessel with loop-handle (Chinese name is you), which was fabricated in Shang Dynasty (1700 B.C.–1100 B.C.) and now is collected in Xiaogan Museum, Hubei province of China. The microstructures of the product were characterized systematically by using optical microscopy, scanning electron microscope, transmission electron microscope, X-ray diffraction, and Raman microscopy. The experimental results revealed that the product belonged to a kind of malachite with high purity and high crystallinity. The growth of the product was considered to be a possible reason that the vessel was overly airtight within a museum display cabinet besides a lid of the vessel, which made the excess of H 2 O and CO 2 gas concentrations inside the vessel during long-term storage. This corrosion product is very harmful to bronze cultural relics, because of a large amount of copper consumption from the matrix which will reduce its life. The growth mechanism of the specific stalactitic product and the suggestions for preservation of the similar bronze relics in museum were proposed. - Highlights: ► The stalactitic product was the high purity and good crystallinity malachite. ► Its growth was related to the excess of H 2 O and CO 2 gas concentrations in museum. ► It is harmful to the bronzes, because copper will be consumed from the matrix. ► The suggestions for preservation of the similar bronzes in museum were proposed.

  18. Blood pressure, salivary cortisol, and inflammatory cytokine outcomes in senior female cancer survivors enrolled in a tai chi chih randomized controlled trial. (United States)

    Older cancer survivors are a vulnerable population due to an increased risk for chronic diseases (e.g., cardiovascular disease) compounded with treatment late-effects and declines in physical functioning. Therefore, interventions that reduce chronic disease risk factors (i.e., blood pressure, chronic inflammation, and cortisol) are important in this population. Tai chi chih (TCC) is a mind-body exercise associated with reductions in chronic disease risk factors, but has not been examined with older cancer survivors. In a feasibility randomized controlled trial of TCC, we examined secondary outcomes of blood pressure, salivary cortisol, and inflammatory cytokines (interleukin (IL)-6, IL-12, tumor necrosis factor-α, IL-10, IL-4) due to their implications in chronic diseases. Sixty-three senior female cancer survivors (M age = 67 years, SD = 7.15) with physical functioning limitations (SF-12 physical functioning ≤80 or role-physical ≤72) were randomized to 12-weeks (60-min, three times a week) of TCC or Health Education control (HEC) classes. Resting blood pressure, 1-day salivary cortisol samples, and fasting plasma samples for cytokine multiplex assays were collected at baseline and 1-week post-intervention. Controlling for baseline values, the TCC group had significantly lower systolic blood pressure (SBP, p = 0.002) and cortisol area-under-curve (AUC, p = 0.02) at post-intervention than the HEC group. There was no intervention effect on inflammatory cytokines (p's > 0.05). This TCC feasibility trial was associated with significant reductions in SBP and cortisol AUC in senior female cancer survivors. Larger, definitive trials are needed to confirm these findings. Senior survivors' have an increased risk for chronic diseases; however, TCC interventions may help reduce associated risk factors.

    Purpose Cognitive behavioral therapy for insomnia (CBT-I) and Tai Chi Chih (TCC), a movement meditation, improve insomnia symptoms. Here, we evaluated whether TCC is noninferior to CBT-I for the treatment of insomnia in survivors of breast cancer. Patients and Methods This was a randomized, partially blinded, noninferiority trial that involved survivors of breast cancer with insomnia who were recruited from the Los Angeles community from April 2008 to July 2012. After a 2-month phase-in period with repeated baseline assessment, participants were randomly assigned to 3 months of CBT-I or TCC and evaluated at months 2, 3 (post-treatment), 6, and 15 (follow-up). Primary outcome was insomnia treatment response-that is, marked clinical improvement of symptoms by the Pittsburgh Sleep Quality Index-at 15 months. Secondary outcomes were clinician-assessed remission of insomnia; sleep quality; total sleep time, sleep onset latency, sleep efficiency, and awake after sleep onset, derived from sleep diaries; polysomnography; and symptoms of fatigue, sleepiness, and depression. Results Of 145 participants who were screened, 90 were randomly assigned (CBT-I: n = 45; TCC: n = 45). The proportion of participants who showed insomnia treatment response at 15 months was 43.7% and 46.7% in CBT-I and TCC, respectively. Tests of noninferiority showed that TCC was noninferior to CBT-I at 15 months ( P = .02) and at months 3 ( P = .02) and 6 ( P insomnia remission was 46.2% and 37.9% in CBT-I and TCC, respectively. CBT-I and TCC groups showed robust improvements in sleep quality, sleep diary measures, and related symptoms (all P insomnia. TCC, a mindful movement meditation, was found to be statistically noninferior to CBT-I, the gold standard for behavioral treatment of insomnia.

    Dynamic vegetation model ORCHIDEE (Organizing Carbon and Hydrology In Dynamic EcosystEms) is a state of art land surface component of the IPSL (Institute Pierre Simon Laplace) Earth System Model. It has been used world-wide to investigate variations of water, carbon, and energy exchanges between the land surface and the atmosphere. In this study we assessed the applicability of using ORCHIDEE-CAN, a new feature with 3-D CANopy structure (Naudts et al., 2015; Ryder et al., 2016), to simulate surface fluxes measured at tower-based eddy covariance fluxes at the Lien-Hua-Chih experimental watershed in Taiwan. The atmospheric forcing including radiation, air temperature, wind speed, and the dynamics of vertical canopy structure for driving the model were obtained from the observations site. Suitable combinations of default plant function types were examined to meet in-situ observations of soil moisture and leaf area index from 2009 to 2013. The simulated top layer soil moisture was ranging from 0.1 to 0.4 and total leaf area was ranging from 2.2 to 4.4, respectively. A sensitivity analysis was performed to investigate the sensitive of model parameters and model skills of ORCHIDEE-CAN on capturing seasonal variations of surface fluxes. The most sensitive parameters were suggested and calibrated by an automatic data assimilation tool ORCHDAS (ORCHIDEE Data Assimilation Systems; Latent heat, sensible heat, and carbon fluxes simulated by the model were compared with long-term observations at the site. ORCHIDEE-CAN by making use of calibrated surface parameters was used to study variations of land-atmosphere interactions on a variety of temporal scale in associations with changes in both land and atmospheric conditions.

  5. Inhibitory effect of bofutsushosan (fang feng tong sheng san) on glucose transporter 5 function in vitro. (United States)

    Gao, Shengli; Satsu, Hideo; Makino, Toshiaki


    Bofutsushosan (BTS; fang feng tong sheng san in Chinese) is a formula in traditional Japanese Kampo medicine and Chinese medicine comprising eighteen crude drugs, and is used to treat obesity and metabolic syndrome. Fructose is contained in refreshing beverages as high-fructose corn syrup, and is associated with obesity. Fructose is absorbed via glucose transporter 5 (GLUT5) in the intestine. Therefore, the inhibition of GLUT5 is considered to be a target of obesity drugs. We evaluated the inhibitory effects of BTS extract and its constituents on fructose uptake using Chinese hamster ovary K1 cells, i.e., cells stably expressing GLUT5. Boiled water extract of BTS significantly suppressed GLUT5 function in a concentration-dependent manner without cytotoxicities. Among 18 components of BTS, the boiled water extracts of the rhizome of Zingiber officinale, the root and rhizome of Saposhnikovia divaricata, and the root of Platycodon grandiflorum exhibited significant inhibitory effects on fructose uptake with IC 50 values of 314, 119 and 475 µg/ml, respectively. Among the constituents of the rhizome of Z. officinale extract, 6-gingerol significantly inhibited GLUT5 with an IC 50 value of 39 µM, while 6-shogaol exhibited a significant but weak inhibition on GLUT5 at 100 µM. One of the mechanisms of action of BTS may be the inhibition of fructose absorption in the intestine, and one of the active components of BTS is the rhizome of Z. officinale and 6-gingerol.

    sources. The list of foreign ethnonyms is large even in the Shang oracles inscriptions. As has been suggested, the Shang distinguished subdued people from hostile outer tribes, indicated by the term fang. Among the peoples noted in the Shang period, most important were the Qiang, Zhou, Quan, Guifang and Yifang. The Qiang and Zhou may have been allied against the Shang, who on their part had special ties with the Quan. The Zhou ultimately led a coalition of peoples against the last Shang ruler precisely at the moment when he was battling in the East against the Yifang. In the following Zhou period, the term fang gradually disappeared and most foreign peoples were to be denoted as Yi (formerly Yifang, Man, Rong and Di. The Zhou also faced a particular threat from the Quanrong (Quan and in the 10th century B.P. deported many of them into outlaying regions – later the Zhou were attacked by a people of unknown origin, the Xianyun, and although the attack was repelled, by the 8th century the Quanrong revived and captured the Zhou capital. This led to the foundation of a new capital in the East, followed by several centuries in which the rulers of various Chinese states assumed a hegemonistic position. It was in this period that the Chinese finally formulated a worldview of themselves as the “Middle Kingdom“, surrounded by “barbarians of the four corners“ – i.e. Yi in the East, Man in the south, Rong in the West and Di in the North. This can be seen as the “first circle“ of foreign peoples around Ancient Chine. Yet when the Chinese state Zhao and later Qin (whose rulers may have originated from the Quanrong expanded to the Ordos and Mongolian border, they reached also a “second circle“ of peoples – in dicated by the ethnonyms Hu, Xiongnu and Yuezhi. Sources at the time also provide often-fantastic references to even further peoples, such as the Dingling in Siberia, who would have constituted a “third circle“ around China. In the final section of the

    Full Text Available The present study investigates the potential therapeutic mechanism underlying the effects of the Chinese herbal formula Hongqijiangzhi Fang (HJF on nonalcoholic fatty liver disease (NAFLD in rats. Male Sprague Dawley (SD rats were randomly divided into 4 groups (n=8: control group was fed a normal diet, three other groups were fed high-fat diets (HFD, and the two treatment groups were intragastrically given a compound probiotic or HJF during the molding time. After 16 w, related indices were detected. The results showed that HJF significantly reduced abdominal aorta serum cholesterol (TC, triglyceride (TG, low-density lipoprotein (LDL, IL-1β, and IL-18, portal venous serum lipopolysaccharide (LPS, and liver TC and TG levels in HFD-fed rats. HJF ameliorated hepatic steatosis in the liver and improved the intestinal barrier in HFD-fed rats. Activation of the NLRP3 inflammasome was reduced by HJF in HFD-fed rats. Additionally, the abundances of A. muciniphila (Verrucomicrobiaceae, F. rappini (Helicobacteraceae, and Enterobacteriaceae bacteria significantly decreased in HJF-treated HFD-fed rats. In conclusion, these result suggested that the Chinese herbal formula HJF reduced hepatic steatosis maybe through decreasing certain gut bacteria (such as Enterobacteriaceae bacteria and F. rappini, alleviating intestinal endotoxemia and reducing NLRP3 inflammasome activation.

    Full Text Available Resumen: Una lectura sobre los estudios narratológicos revela que el acto narrativo es un hecho consustancial al ser humano. “Somos el homo sapiens, porque somos el homo narrans”, diría el académico José María Merino (2002: 57. De las estructuras narrativas, el cuento oral tradicional se alza como la forma más antigua. Tan antigua y presente en todos los pueblos que componentes semánticos y formales se repiten en relatos de distintas culturas. Tales aspectos constituyen el objeto de análisis de este repertorio de cuentos fantásticos de Guinea Ecuatorial transmitidos en lengua española. En dicho entorno, el cuento oral fang se manifiesta como un arte viviente. No es un evento pensado sólo para niños; toda la comunidad participa de esta “fiesta” que se verá enaltecida por la presencia del canto. Dada la escasa proliferación de estudios del relato oral africano y en particular del guineano, se hace imperativo partir de estudios occidentales, lo cual nos desliza hacia el terreno del comparativismo. Sin embargo, no siempre dichos estudios son confirmados en esta investigación que concluye con las siguientes tesis: el criterio verdad y ficción al que se recurre para delimitar ciertas narraciones tradicionales europeas queda difuminado; uso irregular de las fórmulas de abertura y cierre; la asignación del fin lúdico de los cuentos fantásticos se acompaña del didáctico y la pretendida universalización del método estructuralista formal de Vladimir Propp, expuesta en Morfología del cuento (1987, se vislumbra inoperante, pues quedan reducidas las treinta y una funciones y la sucesión lineal de las mismas. Los temas y los motivos, arropados por el espíritu de la cultura donde emergen, son similares a los identificados en compilaciones españolas o internacionales. Finalmente, la naturaleza oral tradicional del repertorio queda patente a través de las nueve “Leyes Épicas” establecidas por Axel Orlik (1965: la Ley de

It is widely used in traditional Chinese medicine for treating postpartum depression (PPD. Previous studies have shown that SJF treats PPD through the neuroendocrine mechanism. Aim: To further investigate the effect of SJF on the immune system, including the inflammatory response system and CD4+CD25+ regulatory T (Treg cells. Materials and methods: Sprague Dawley rats were used to create an animal model of PPD by inducing hormone-simulated pregnancy followed by hormone withdrawal. After hormone withdrawal, the PPD rats were treated with SJF or fluoxetine for 1, 2, and 4 weeks. Levels of Treg cells in peripheral blood were measured by flow cytometry analysis. Serum interleukin (IL-1β and IL-6 were evaluated by enzyme-linked immunosorbent assay, and gene and protein expressions of IL-1RI, IL-6Rα, and gp130 in the hippocampus were observed by reverse-transcription polymerase chain reaction and Western blot. Results: Serum IL-1β in PPD rats increased at 2 weeks and declined from then on, while serum IL-6 increased at 1, 2, and 4 weeks. Both IL-1β and IL-6 were downregulated by SJF and fluoxetine. Changes in gene and protein expressions of IL-1RI and gp130 in PPD rats were consistent with changes in serum IL-1β, and were able to be regulated by SJF and fluoxetine. The levels of Treg cells were negatively correlated with serum IL-1β and IL-6, and were decreased in PPD rats. The levels of Treg cells were increased by SJF and fluoxetine. Conclusion: Dysfunction of proinflammatory cytokines and Tregs in different stages of PPD was attenuated by SJF and fluoxetine through

    Full Text Available Objective. To investigate the effects of Qi-Fang-Xi-Bi-Granules (QFXBGs on cartilage morphology and methylation of C/ebpα (CCAAT/enhancer binding proteinα at the promoter region. Methods. Knee osteoarthritis (KOA modeling was performed in rats in accordance with Hulth’s method, and control group received sham operation. Eight weeks after KOA modeling, the rats in the KOA modeling group were further divided into 6 groups. Each group was given the appropriate drug. After 8 weeks, half of the rats were used for Micro-CT scan, HE staining, ABH/OG staining, immunohistochemistry, and TUNNEL staining of the knee joint tissue, and the other half were used to examine C/ebpα promoter methylation. Results. The three dose groups of QFXBGs all showed lower degrees of surface fissures and flaking, thicker cartilage layer, and restored chondrocyte and subchondral bone morphology, compared with the KOA model group. C/ebpα-22 promoter methylation levels in the high- and low-dose groups were significantly higher than that in the KOA modeling group (p<0.05, while C/ebpα-2 promoter methylation level in the medium-dose group was significantly higher than that in the KOA modeling group (p<0.05. Conclusions. QFXBGs may alleviate articular cartilage degeneration through promoting C/ebpα-2 or C/ebpα-22 methylation at specific promoter sites.

    To investigate the effects of Bushen Huoxue Fang (BSHX) on the apoptosis of epithelial cells in the prostatic ductal system of rats with benign prostatic hyperplasia (BPH) and its possible action mechanism. One hundred 3- month-old male Wistar rats were randomly divided into four groups of equal number (control, castrated, BPH model, and BSHX). BPH models were made by subcutaneous injection of testosterone following castration; the rats in the BSHX group were treated intragastrically with BSHX at 2.34 g/ml after modeling, while those in the other two groups with equal volume of saline, all for 37 days. On the 38th day, all the rats were sacrificed and their prostates harvested for detection of the distribution of TGF-beta1 and alpha-actin and the count of positive cells in the prostatic ductal system by immunohistochemical staining. The apoptosis rate of epithelial cells in the prostatic ductal system was determined by TUNEL assay. The expression of TGF-beta1 was significantly increased in the rats of the BSHX group as compared with the BPH models in both the proximal prostatic duct ([15.28 +/- 4.30]% vs [36.42 +/- 8.10]%, P epithelial cells in the proximal prostatic duct ([39.42 +/- 9.20]% vs [3.86 +/- 1.34]%, P epithelial cells in the prostatic ductal system was significantly higher in the BSHX-treated rats than in the BPH models (P epithelial cells, and thus effectively inhibit benign prostatic hyperplasia.

    An on-line near infrared (NIR) spectroscopy monitoring method with an appropriate multivariate calibration method was developed for the extraction process of Fu-fang Shuanghua oral solution (FSOS). On-line NIR spectra were collected through two fiber optic probes, which were designed to transmit NIR radiation by a 2 mm flange. Partial least squares (PLS), interval PLS (iPLS) and synergy interval PLS (siPLS) algorithms were used comparatively for building the calibration regression models. During the extraction process, the feasibility of NIR spectroscopy was employed to determine the concentrations of chlorogenic acid (CA) content, total phenolic acids contents (TPC), total flavonoids contents (TFC) and soluble solid contents (SSC). High performance liquid chromatography (HPLC), ultraviolet spectrophotometric method (UV) and loss on drying methods were employed as reference methods. Experiment results showed that the performance of siPLS model is the best compared with PLS and iPLS. The calibration models for AC, TPC, TFC and SSC had high values of determination coefficients of (R2) (0.9948, 0.9992, 0.9950 and 0.9832) and low root mean square error of cross validation (RMSECV) (0.0113, 0.0341, 0.1787 and 1.2158), which indicate a good correlation between reference values and NIR predicted values. The overall results show that the on line detection method could be feasible in real application and would be of great value for monitoring the mixed decoction process of FSOS and other Chinese patent medicines.

    Zacharia, Susan; Taylor, E Laurette; Hofford, Craig W; Brittain, Danielle R; Branscum, Paul W


    The purpose of this study was to determine the effectiveness of an 8-week Tai Chi Chih exercise program on physical functional performance (PFP) among women aged 45 to 65 years. A quasi-experimental design with a nonequivalent comparison group was used. Forty-one healthy inactive women were assigned to either an intervention group (n = 19) or a comparison group (n = 19). A 60-min Tai Chi Chih exercise class was conducted twice a week for 8 weeks. PFP was measured at baseline and postintervention using the Continuous Scale Physical Functional Performance-10 (CS-PFP 10). Between-group differences were analyzed using one-way analysis of covariance (ANCOVA). After participating in the 8-week program, intervention group participants showed greater improvement in the CS-PFP measures (p .06). However, the comparison group had little changes. The findings from this study suggest that participation in an 8-week Tai Chi Chih exercise program can improve PFP in healthy, community-dwelling middle-aged women. © The Author(s) 2013.

  17. Herbal medicine Guan Chang Fu Fang enhances 5-fluorouracil cytotoxicity and affects drug-associated genes in human colorectal carcinoma cells. (United States)

    Yu, Chen; Liu, Shen-Lin; Qi, Ming-Hao; Zou, Xi; Wu, Jian; Zhang, Jing


    Guan Chang Fu Fang (GCFF) is a natural compound, which is extracted from three medicinal plants, Agrimonia pilosa Ledeb ., Patrinia scabiosaefolia and Solanum nigrum L . GCFF has demonstrated clinical efficacy in the treatment of colon cancer. At present, 5-fluorouracil (5-FU) is the primary active chemotherapeutic agent used for treating colon cancer. Using median-effect and apoptosis analyses, fluorescence microscopy and western blotting, the present study analyzed the association between GCFF and 5-FU in the human colon adenocarcinoma LoVo cell line. The effect of GCFF on the expression of chemotherapeutic agent-associated genes was also investigated. The results of the synergistic analysis revealed that GCFF exhibited a significant effect upon 5-FU-associated cytotoxicity within the LoVo cell line. This effect was observed over a broad dose-inhibition range (5-95%), but was particularly significant in the lower concentrations. The flow cytometry results revealed that low doses of GCFF or 5-FU induced S-phase arrest, as did a low-dose combination of the two drugs. After 48 h, GCFF significantly suppressed the expression levels of the chemotherapeutic agent resistance-associated genes within the colon cancer cells. The western blot analysis revealed that the combined effects of 5-FU and GCFF were due to a regulation of the B-cell lymphoma-2 family of proteins. The findings of the present study suggested that GCFF, when combined with 5-FU, has the potential to be a novel, chemotherapeutic compound for the treatment of colon cancer.

As nanotechnology grows rapidly, its biosafety and toxicity have frequently raised concerns. However, diverse results have been reported about the safety of SiNPs; several studies reported that smaller particles might exhibit toxic effects to some cell lines, and larger particles of 100 nm were reported to be genotoxic to the cocultured cells. Here, we investigated the in vivo toxicity of SiNPs of 150 nm in various dosages via intravenous administration in mice. The mice were observed for 14 days before blood examination and histopathological assay. All the mice survived and behaved normally after the administration of nanoparticles. No significant weight change was noted. Blood examinations showed no definite systemic dysfunction of organ systems. Histopathological studies of vital organs confirmed no SiNP-related adverse effects. We concluded that 150 nm SiNPs were biocompatible and safe for in vivo use in mice.

  1. Structural analysis of group II chitinase (ChtII) catalysis completes the puzzle of chitin hydrolysis in insects. (United States)

    Chen, Wei; Qu, Mingbo; Zhou, Yong; Yang, Qing


    Chitin is a linear homopolymer of N -acetyl-β-d-glucosamines and a major structural component of insect cuticles. Chitin hydrolysis involves glycoside hydrolase family 18 (GH18) chitinases. In insects, chitin hydrolysis is essential for periodic shedding of the old cuticle ecdysis and proceeds via a pathway different from that in the well studied bacterial chitinolytic system. Group II chitinase (ChtII) is a widespread chitinolytic enzyme in insects and contains the greatest number of catalytic domains and chitin-binding domains among chitinases. In Lepidopterans, ChtII and two other chitinases, ChtI and Chi-h, are essential for chitin hydrolysis. Although ChtI and Chi-h have been well studied, the role of ChtII remains elusive. Here, we investigated the structure and enzymology of Of ChtII, a ChtII derived from the insect pest Ostrinia furnacalis We present the crystal structures of two catalytically active domains of Of ChtII, Of ChtII-C1 and Of ChtII-C2, both in unliganded form and complexed with chitooligosaccharide substrates. We found that Of ChtII-C1 and Of ChtII-C2 both possess long, deep substrate-binding clefts with endochitinase activities. Of ChtII exhibited structural characteristics within the substrate-binding cleft similar to those in Of Chi-h and Of ChtI. However, Of ChtII lacked structural elements favoring substrate binding beyond the active sites, including an extra wall structure present in Of Chi-h. Nevertheless, the numerous domains in Of ChtII may compensate for this difference; a truncation containing one catalytic domain and three chitin-binding modules ( Of ChtII-B4C1) displayed activity toward insoluble polymeric substrates that was higher than those of Of Chi-h and Of ChtI. Our observations provide the last piece of the puzzle of chitin hydrolysis in insects. © 2018 by The American Society for Biochemistry and Molecular Biology, Inc.

    Jingning fang (JNF) is an effective Traditional Chinese Medicine (TCM) which is used for the treatment of Attention Deficit Hyperactivity Disorder (ADHD). To clarify the bioactive constituents of JNF, a Thermo Q Exactive™ Plus Orbitrap™ mass spectrometer was used in this study. More than 127 chemical compounds were isolated and identified tentatively in the JNF extract, while 42 prototype constituents with 4 potential metabolites were identified tentatively in rat plasma. A method for simultaneous determination of polygalaxanthone III (PAIII), sibiricose A 5 (A 5 ), sibiricose A 6 (A 6 ), 3, 6'-disinapoyl sucrose (3,6'-DISS), tenuifoliside C (TEC), tenuifolin B (TNB), verbascoside (VCE), heterophyllin B (HEB) and schisandrin (SCH) in rat was developed and validated using polydatin (PLN) and psoralen (PSN) as internal standards. All calibration curves proved favorable linearity (R 2 ≥0.9923) in linear ranges. The lower limit of quantification (LLOQ) was 2.5ng/mL for PAIII, A 5 , 3, 6'-DISS, TNB, VCE, HEB and SCH, 1.0ng/mL for A 6 and TEC, respectively. Intra-day and inter-day precisions didn't exceed 14.0% for all the analytes. Extraction recoveries and matrix effects of analytes and IS were acceptable. The validated method has been successfully applied to the pharmacokinetics (PK) studies of the nine compounds in JNF. These findings are useful for predicting the bioactive components of JNF, and will aid in optimizing dose regimens of the drug. Copyright © 2017. Published by Elsevier B.V.

  3. Chemical profiles and pharmacological activities of Chang-Kang-Fang, a multi-herb Chinese medicinal formula, for treating irritable bowel syndrome. (United States)

    Chang-Kang-Fang formula (CKF), a multi-herb traditional Chinese medicinal formula, has been clinically used for treatment of irritable bowel syndrome (IBS). The mechanisms of CKF for treating IBS and the components that are responsible for the activities were still unknown. To investigate the chemical profiles and effects of CKF on IBS model. The chemical profiles of CKF were investigated by ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q/TOF-MS/MS). On colon irritation induced rat neonates IBS model, the influence of CKF on neuropeptides, including substance P (SP), calcitonin gene-related peptide (CGRP), vasoactive intestinal polypeptide (VIP) and 5-hydroxytryptamine (5-HT), were measured by ELISA, and the effect on intestinal sensitivity was assessed based on the abdominal withdrawal reflex (AWR) scores. In addition, the activities of CKF against acetic acid-induced nociceptive responses and prostigmin methylsulfate triggered intestinal propulsion in mice were also evaluated. 80 components were identified or tentatively assigned from CKF, including 11 alkaloids, 20 flavanoids, 4 monoterpenoids, 9 iridoid glycoside, 9 phenylethanoid glycosides, 10 chromones, 7 organic acid, 3 coumarins, 2 triterpene and 5 other compounds. On IBS rat model, CKF was observed to reduce AWR scores and levels of SP, CGRP, VIP and 5-HT. Moreover, CKF reduced the acetic acid-induced writhing scores at all dosages and reduced the intestinal propulsion ration at dosage of 7.5 and 15.0g/kg/d. CKF could alleviate the symptoms of IBS by modulating the brain-gut axis through increasing the production of neuropeptides such as CGRP, VIP, 5-HT and SP, releasing pain and reversing disorders of intestinal propulsion. Berberine, paeoniflorin, acteoside, flavonoids and chromones may be responsible for the multi-bioactivities of CKF. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

  4. Structural and compositional analysis of a casting mold sherd from ancient China. (United States)

    Casting had symbolic significance and was strictly controlled in the Shang dynasty of ancient China. Vessel casting was mainly distributed around the Shang capital, Yin Ruins, which indicates a rigorous centralization of authority. Thus, for a casting mold to be excavated far from the capital region is rare. In addition to some bronze vessel molds excavated at the Buyao Village site, another key discovery of a bronze vessel mold occurred at Daxinzhuang. The Daxinzhuang site was a core area in the east of Shang state and is an important site to study the eastward expansion of the Shang. Here, combining synchrotron X-rays and other physicochemical analysis methods, nondestructive three-dimensional structure imaging and different elemental analyses were conducted on this mold sherd. Through high penetration X-ray tomography, we obtained insights on the internal structure and discovered some pores. We infer that the generation of pores inside the casting mold sherd was used to enhance air permeability during casting. Furthermore, we suppose that the decorative patterns on the surface were carved and not pasted onto it. Considering the previous compositional studies of bronze vessels, the copper and iron elements were analyzed by different methods. Unexpectedly, a larger amount of iron than of copper was detected on the surface. According to the data analysis and archaeological context, the source of iron on the casting mold sherd could be attributed to local soil contamination. A refined compositional analysis confirms that this casting mold was fabricated locally and used for bronze casting.

    Some important work worldwide in environmental science, like urban air pollution, discharges of radioactive wastes from nuclear plants, and global climate change were introduced. Based on the improvements of facility and studies on 14 C dating method, a precision better than 0.5% has been reached for the PKUAMS. A large number of samples have been measured for the Xia-Shang-Zhou Chronology project. 14 C data of PKUAMS have made important contributions to creation of more reliable chronological table of Xia, Shang and Zhou dynasties. The improvements of PKUAMS are of benefit to the applications in environmental science in the future

  7. The 2005 meta-analysis of homeopathy: the importance of post-publication data. (United States)

    Rutten, A L B; Stolper, C F


    There is a discrepancy between the outcome of a meta-analysis published in 1997 of 89 trials of homeopathy by Linde et al and an analysis of 110 trials by Shang et al published in 2005, these reached opposite conclusions. Important data were not mentioned in Shang et al's paper, but only provided subsequently. What was the outcome of Shang et al's predefined hypotheses? Were the homeopathic and conventional trials comparable? Was subgroup selection justified? The possible role of ineffective treatments. Was the conclusion about effect justified? Were essential data missing in the original article? Analysis of post-publication data. Re-extraction and analysis of 21 higher quality trials selected by Shang et al with sensitivity analysis for the influence of single indications. Analysis of comparability. Sensitivity analysis of influence of subjective choices, like quality of single indications and of cut-off values for 'larger samples'. The quality of trials of homeopathy was better than of conventional trials. Regarding smaller trials, homeopathy accounted for 14 out of 83 and conventional medicine 2 out of 78 good quality trials with nhomeopathy. Quality was assessed differently from previous analyses. Selecting subgroups on sample size and quality caused incomplete matching of homeopathy and conventional trials. Cut-off values for larger trials differed between homeopathy and conventional medicine without plausible reason. Sensitivity analyses for the influence of heterogeneity and the cut-off value for 'larger higher quality studies' were missing. Homeopathy is not effective for muscle soreness after long distance running, OR=1.30 (95% CI 0.96-1.76). The subset of homeopathy trials on which the conclusion was based was heterogeneous, comprising 8 trials on 8 different indications, and was not matched on indication with those of conventional medicine. Essential data were missing in the original paper. Re-analysis of Shang's post-publication data did not support

  11. Water organic pollution and eutrophication influence soil microbial processes, increasing soil respiration of estuarine wetlands: site study in jiuduansha wetland. (United States)

    Zhang, Yue; Wang, Lei; Hu, Yu; Xi, Xuefei; Tang, Yushu; Chen, Jinhai; Fu, Xiaohua; Sun, Ying


    Undisturbed natural wetlands are important carbon sinks due to their low soil respiration. When compared with inland alpine wetlands, estuarine wetlands in densely populated areas are subjected to great pressure associated with environmental pollution. However, the effects of water pollution and eutrophication on soil respiration of estuarine and their mechanism have still not been thoroughly investigated. In this study, two representative zones of a tidal wetland located in the upstream and downstream were investigated to determine the effects of water organic pollution and eutrophication on soil respiration of estuarine wetlands and its mechanism. The results showed that eutrophication, which is a result of there being an excess of nutrients including nitrogen and phosphorus, and organic pollutants in the water near Shang shoal located upstream were higher than in downstream Xia shoal. Due to the absorption and interception function of shoals, there to be more nitrogen, phosphorus and organic matter in Shang shoal soil than in Xia shoal. Abundant nitrogen, phosphorus and organic carbon input to soil of Shang shoal promoted reproduction and growth of some highly heterotrophic metabolic microorganisms such as β-Proteobacteria, γ-Proteobacteria and Acidobacteria which is not conducive to carbon sequestration. These results imply that the performance of pollutant interception and purification function of estuarine wetlands may weaken their carbon sequestration function to some extent.

  12. Primary structure and subcellular localization of two fimbrial subunit-like proteins involved in the biosynthesis of K99 fibrillae. (United States)

    Roosendaal, E; Jacobs, A A; Rathman, P; Sondermeyer, C; Stegehuis, F; Oudega, B; de Graaf, F K


    Analysis of the nucleotide sequence of the distal part of the fan gene cluster encoding the proteins involved in the biosynthesis of the fibrillar adhesin, K99, revealed the presence of two structural genes, fanG and fanH. The amino acid sequence of the gene products (FanG and FanH) showed significant homology to the amino acid sequence of the fibrillar subunit protein (FanC). Introduction of a site-specific frameshift mutation in fanG or fanH resulted in a simultaneous decrease in fibrillae production and adhesive capacity. Analysis of subcellular fractions showed that, in contrast to the K99 fibrillar subunit (FanC), both the FanH and the FanG protein were loosely associated with the outer membrane, possibly on the periplasmic side, but were not components of the fimbriae themselves.

  13. Non-front-fanged colubroid ("colubrid") snakebites: three cases of local envenoming by the mangrove or ringed cat-eyed snake (Boiga dendrophila; Colubridae, Colubrinae), the Western beaked snake (Rhamphiophis oxyrhynchus; Lamprophiidae, Psammophinae) and the rain forest cat-eyed snake (Leptodeira frenata; Dipsadidae). (United States)

    Weinstein, S A; Griffin, R; Ismail, A K


    Non-front-fanged colubroid snakes (NFFC; formerly and artificially taxonomically assembled as "colubrids") comprise the majority of extant ophidian species. Although the medical risks of bites by a handful of species have been documented, the majority of these snakes have oral products (Duvernoy's secretions, or venoms) with unknown biomedical properties/unverified functions and their potential for causing harm in humans is unknown. Described are three cases of local envenoming from NFFC bites inflicted respectively by the mangrove or ringed cat-eyed snake (Boiga dendrophila, Colubridae), the Western beaked snake (Rhamphiophis oxyrhynchus, Lamprophiidae) and the rain forest cat-eyed snake (Leptodeira frenata, Dipsadidae). The effects ranged from mild pain, edema and erythema to severe pain, progressive edema, and blistering with slowly resolving arthralgia; there were no systemic effects. Although these three taxa occasionally inflict bites with mild to moderate local effects, there is no current evidence of systemic involvement. Two of these cases were reported to one of the authors for medical evaluation, and although verified, thus constitute reliably reported cases, but low-quality evidence. Type-1 local hypersensitivity may contribute to some cases, but most local effects observed or reported in these three cases were consistent with the effects of venom/oral product components.

  17. Colubrid Venom Composition: An -Omics Perspective. (United States)

    Junqueira-de-Azevedo, Inácio L M; Campos, Pollyanna F; Ching, Ana T C; Mackessy, Stephen P


    Snake venoms have been subjected to increasingly sensitive analyses for well over 100 years, but most research has been restricted to front-fanged snakes, which actually represent a relatively small proportion of extant species of advanced snakes. Because rear-fanged snakes are a diverse and distinct radiation of the advanced snakes, understanding venom composition among "colubrids" is critical to understanding the evolution of venom among snakes. Here we review the state of knowledge concerning rear-fanged snake venom composition, emphasizing those toxins for which protein or transcript sequences are available. We have also added new transcriptome-based data on venoms of three species of rear-fanged snakes. Based on this compilation, it is apparent that several components, including cysteine-rich secretory proteins (CRiSPs), C-type lectins (CTLs), CTLs-like proteins and snake venom metalloproteinases (SVMPs), are broadly distributed among "colubrid" venoms, while others, notably three-finger toxins (3FTxs), appear nearly restricted to the Colubridae (sensu stricto). Some putative new toxins, such as snake venom matrix metalloproteinases, are in fact present in several colubrid venoms, while others are only transcribed, at lower levels. This work provides insights into the evolution of these toxin classes, but because only a small number of species have been explored, generalizations are still rather limited. It is likely that new venom protein families await discovery, particularly among those species with highly specialized diets.

  18. Summary of bi-shRNA/GM-CSF augmented autologous tumor cell immunotherapy (FANG™) in advanced cancer of the liver. (United States)

    Therapies for advanced hepatocellular carcinoma (HCC) are limited. We carried out a phase I trial of a novel autologous whole-cell tumor cell immunotherapy (FANG™), which incorporates a dual granulocyte macrophage colony-stimulating factor (GM-CSF) expressive/bifunctional small hairpin RNA interference (bi-shRNAi) vector. The bi-shRNAi DNA targets furin, which is a proconvertase of transforming growth factors beta (TGFβ) 1 and 2. Safety, mechanism, immunoeffectiveness, and suggested benefit were previously shown [Senzer et al.: Mol Ther 2012;20:679-689; Senzer et al.: J Vaccines Vaccin 2013;4:209]. We now provide further follow-up of a subset of 8 HCC patients. FANG manufacturing was successful in 7 of 8 attempts (one failure due to insufficient cell yield). Median GM-CSF expression was 144 pg/10(6) cells, TGFβ1 knockdown was 100%, and TGFβ2 knockdown was 93% of the vector-transported cells. Five patients were vaccinated (1 or 2.5×10(7) cells/intradermal injection, 6-11 vaccinations). No FANG toxicity was observed. Three of these patients demonstrated evidence of an immune response to the autologous tumor cell sample. Long-term follow-up demonstrated survival of 319, 729, 784, 931+, and 1,043+ days of the FANG-treated patients. In conclusion, evidence supports further assessment of the FANG immunotherapy in HCC. © 2014 S. Karger AG, Basel.

  19. Follow-up study of a pregnant woman 16 years after exposure in the Xinzhou radiation accident

    To investigate the late effects of radiation on child-bearing women, a follow-up study was performed on a 39-year-old survivor 16 years after a 60 Co radiation accident. The woman, Fang, was 19 weeks pregnant at the time of exposure. Physical examinations, a full range of clinical laboratory and imaging tests, as well as cytogenetic analyses were conducted to evaluate Fang's current health conditions. Fang shows the appearance of premature ageing and has a decreased menstrual period. Laboratory studies and imaging tests suggest nodular goitre disease and osteoporosis. Otherwise, no apparent abnormalities were found in the major organs. No malignant tumours were detected by either tumour markers or imaging tests. However, the existence of chromosome aberrations warrants long-term follow-up for tumour incidence in the future. Fang became pregnant 8 years after the accident, but suffered a miscarriage due to the death of the foetus at 6 months into the pregnancy. In conclusion, our findings suggest that the intrauterine death of the foetus might be associated with the previous exposure. There is no evidence of malignant tumours as of the date of the follow-up study. Non-cancerous diseases, i.e. thyroid disease and osteoporosis, which may be related to radiation exposure, are the major manifestations of the long-term effects of the accident. (note)

    Brink, D M; Canto, L F


    The multi-dimensional diffusion approach of Zhang Jing Shang and Weidenmueller (1983 Phys. Rev. C28, 2190) is used to study a simplified model for induced fission. In this model it is shown that the coupling of the fission coordinate to the intrinsic degrees of freedom is equivalent to an extra friction and a mass correction in the corresponding one-dimensional problem.

  1. Analysis of the grape (Vitis vinifera L.) thaumatin-like protein (TLP) gene family and demonstration that TLP29 contributes to disease resistance. (United States)

    Yan, Xiaoxiao; Qiao, Hengbo; Zhang, Xiuming; Guo, Chunlei; Wang, Mengnan; Wang, Yuejin; Wang, Xiping


    Thaumatin-like protein (TLP) is present as a large family in plants, and individual members play different roles in various responses to biotic and abiotic stresses. Here we studied the role of 33 putative grape (Vitis vinifera L.) TLP genes (VvTLP) in grape disease resistance. Heat maps analysis compared the expression profiles of 33 genes in disease resistant and susceptible grape species infected with anthracnose (Elsinoe ampelina), powdery mildew (Erysiphe necator) or Botrytis cinerea. Among these 33 genes, the expression level of TLP29 increased following the three pathogens inoculations, and its homolog from the disease resistant Chinese wild grape V. quinquangularis cv. 'Shang-24', was focused for functional studies. Over-expression of TLP29 from grape 'Shang-24' (VqTLP29) in Arabidopsis thaliana enhanced its resistance to powdery mildew and the bacterium Pseudomonas syringae pv. tomato DC3000, but decreased resistance to B. cinerea. Moreover, the stomatal closure immunity response to pathogen associated molecular patterns was strengthened in the transgenic lines. A comparison of the expression profiles of various resistance-related genes after infection with different pathogens indicated that VqTLP29 may be involved in the salicylic acid and jasmonic acid/ethylene signaling pathways.

    Venom is a key innovation underlying the evolution of advanced snakes (Caenophidia). Despite this, very little is known about venom system structural diversification, toxin recruitment event timings, or toxin molecular evolution. A multidisciplinary approach was used to examine the diversification of the venom system and associated toxins across the full range of the approximately 100 million-year-old advanced snake clade with a particular emphasis upon families that have not secondarily evolved a front-fanged venom system ( approximately 80% of the 2500 species). Analysis of cDNA libraries revealed complex venom transcriptomes containing multiple toxin types including three finger toxins, cobra venom factor, cysteine-rich secretory protein, hyaluronidase, kallikrein, kunitz, lectin, matrix metalloprotease, phospholipase A(2), snake venom metalloprotease/a disintegrin and metalloprotease, and waprin. High levels of sequence diversity were observed, including mutations in structural and functional residues, changes in cysteine spacing, and major deletions/truncations. Morphological analysis comprising gross dissection, histology, and magnetic resonance imaging also demonstrated extensive modification of the venom system architecture in non-front-fanged snakes in contrast to the conserved structure of the venom system within the independently evolved front-fanged elapid or viperid snakes. Further, a reduction in the size and complexity of the venom system was observed in species in which constriction has been secondarily evolved as the preferred method of prey capture or dietary preference has switched from live prey to eggs or to slugs/snails. Investigation of the timing of toxin recruitment events across the entire advanced snake radiation indicates that the evolution of advanced venom systems in three front-fanged lineages is associated with recruitment of new toxin types or explosive diversification of existing toxin types. These results support the role of venom

  4. Autolysis at the disintegrin domain of patagonfibrase, a metalloproteinase from Philodryas patagoniensis (Patagonia Green Racer; Dipsadidae) venom. (United States)

    Peichoto, María E; Paes Leme, Adriana F; Pauletti, Bianca A; Batista, Isabel Correia; Mackessy, Stephen P; Acosta, Ofelia; Santoro, Marcelo L


    Patagonfibrase is a 57.5-kDa hemorrhagic metalloproteinase isolated from the venom of Philodryas patagoniensis (Patagonia Green Racer), a South American rear-fanged snake. Herein we demonstrate that patagonfibrase undergoes autolysis at its pH optimum (7.5) and at 37 degrees C, primarily producing a approximately 32.6 kDa fragment composed of disintegrin-like and cysteine-rich domains, as identified by mass spectrometry and N-terminal sequencing. The autolysis site for production of this fragment is similar to that observed for metalloproteinases from front-fanged Viperidae snake venoms. In the presence of Ca(2+), patagonfibrase was only partially autolysed, giving rise mainly to one fragment of approximately 52.2 kDa. In addition, calcium markedly enhanced the azocaseinolytic activity of patagonfibrase. Our findings contribute to the understanding of the structural and mechanistic bases of this family of metalloenzymes that are widely distributed among snake venoms, demonstrating that important post-translational modifications such as proteolysis can also contribute to the diversity and complexity of proteins found in rear-fanged snake venoms.

    Highlights: • Densities and viscosities of tri-n-octylamine + n-heptane, +n-octane, +n-nonane, or +n-decane are determined. • The excess molar volume is calculated. • The Grunberg and Nissan equation and Fang and He equation are used to correlate the binary viscosities. -- Abstract: Densities (ρ) and viscosities (η) for binary mixtures of tri-n-octylamine (TOA) + n-heptane, TOA + n-octane, TOA + n-nonane, and TOA + n-decane are determined at T (283.15, 293.15, and 303.15) K and atmospheric pressure. The excess molar volume is calculated from the density data and is correlated by a Redlich–Kister type equation. The excess molar volume is negative for all the four systems. The results show that the volume accommodation effect is predominant in these systems. The Grunberg and Nissan equation and Fang and He equation for binary mixtures are used to correlate the experimental viscosity data. The Fang and He equation gives an average absolute deviation (AAD%) of 0.8% for TOA with alkane mixtures, better than that of 3.8% given by the Grunberg and Nissan equation

    Full Text Available The History of Tabgach Turks who recorded in Chinese sources under the name of T’o-pa is little known. Tabgachs dominated on Northern China in 386 AD, governed China for nearly two centuries and finally disappeared from the stage of history by becoming Chinese people. Some scholars investigated this period of Tabgachs. However, their emergence to stage of history and their history until 386 AD are little studied. Tabgachs begun to take place in the Chinese sources in years about 160-170. They strengthened their state formation anddominated on all of their neighbors in the period of Li-wei (220-277.They established Tai State under the reign of I-lu in 314 and this statelasted until 376. Especially in the reign of Shih-i-chien (338-376,Tabgach State strengthened and extended its domination from Liaoningin east to Ferghana in west. Largest state formation of Tabgachs isNorthern Wei State that dominated all of China and later becameChinese. Our article aims to study this period lasted until 386 based onfirst chapter of Wei Shu that is official dynastic history of TabgachDynasty. Besides this, it is applied to main sources as Shih Chi, HanShu, Hou Han Shu, San Kuo Chih, Chin Shu, T’ai P’ing Yü Lan, Ts’e FuYüan Kuei, T’ung Chih, Wen Hsien T’ung Kao, Tzu Chih T’ung Chien,T’ung Tien and research studies. We hope to contribute to later studieson political history, linguistics, cultural history about Tabgachs withour study in General Turkic History. Çin kaynaklarında T’o-pa adı altında kaydedilen Tabgaç Türklerinin tarihleri az bilinmektedir.

To synthesize the evidence and provide the hierarchies of different circumcisions for phimosis and redundant prepuce, we performed an overall network meta-analysis (NMA) based on their comparative efficacy and safety. Electronic databases including PubMed, Embase, Wan Fang, VIP, CNKI and CBM database were researched from randomized controlled trials (RCTs) for redundant prepuce or phimosis. We conducted the direct and indirect comparisons by aggregate data drug information system (ADDIS) software. Moreover, consistency models were applied to assess the differences among the male circumcision practices, and the ranks based on probabilities of intervention for the different endpoints were performed. Node-splitting analysis was used to test inconsistency. Eighteen RCTs were included with 6179 participants. Compared with the conventional circumcision(CC), two new styles of circumcisions, the disposable circumcision suture device(DCSD) and Shang Ring circumcision(SRC), provided significantly shorter operation time[DCSD: standardized mean difference (SMD) = -20.60, 95% credible interval(CI) (-23.38, -17.82); SRC: SMD = -19.16, 95%CI (-21.86, -16.52)], shorter wound healing time [DCSD:SMD = -4.19, 95%CI (-8.24,-0.04); SRC: SMD = 4.55, 95%CI (1.62, 7.57); ] and better postoperative penile appearance [DCSD: odds ratios odds ratios (OR) = 11.42, 95%CI (3.60, 37.68); SRC: OR = 3.85,95%CI (1.29, 12.79)]. Additionally, DCSD showed a lower adverse events rate than other two treatments. However, no significant difference was shown in all surgeries for 24 h postoperative pain score. Node-splitting analysis showed that no significant inconsistency was existed (P > 0.05). Based on the results of NMA, DCSD may be a most effective and safest choice for phimosis and redundant prepuce. DCSD has the advantages of a shorter operation

  17. Chinese herbal dose in ancient and modern times: a comparative study. (United States)

    He, Shimin


    Appropriate dose guarantees Chinese herb's safety and effectiveness. There are adult dose criteria for Chinese herbs in decoction in the Pharmacopoeia of the People's Republic of China (2010 Edition) at present. But Chinese herbs have been frequently used in much higher doses than the dose criteria. This study has been conducted to test the dependability of the dose criteria. Twenty Chinese herbs were selected as representatives and their adult doses in decoction in Bei Ji Qian Jin Yao Fang, a famous ancient literature, have been reviewed and compared with those in the Pharmacopoeia of the People's Republic of China (2010 Edition). The adult dose criteria for all these 20 Chinese herbs in the Pharmacopoeia of the People's Republic of China (2010 Edition) haven't covered those in Bei Ji Qian Jin Yao Fang. Furthermore, maximal adult doses in the dose criteria are much lower than those in Bei Ji Qian Jin Yao Fang. The dose criteria in the Pharmacopoeia of the People's Republic of China (2010 Edition) are not comprehensive enough. Studying ancient literatures is an effective method to gain precious Chinese herbs' dose data and helps for new dose criteria's establishment in the future.

  2. Tectonics of the Qinling (Central China): Tectonostratigraphy, geochronology, and deformation history (United States)

    Ratschbacher, L.; Hacker, B.R.; Calvert, A.; Webb, L.E.; Grimmer, J.C.; McWilliams, M.O.; Ireland, T.; Dong, S.; Hu, Jiawen


    The Qinling orogen preserves a record of late mid-Proterozoic to Cenozoic tectonism in central China. High-pressure metamorphism and ophiolite emplacement (Songshugou ophiolite) assembled the Yangtze craton, including the lower Qinling unit, into Rodinia during the ~1.0 Ga Grenvillian orogeny. The lower Qinling unit then rifted from the Yangtze craton at ~0.7 Ga. Subsequent intra-oceanic arc formation at ~470-490 Ma was followed by accretion of the lower Qinling unit first to the intra-oceanic arc and then to the Sino-Korea craton. Subduction then imprinted a ~400 Ma Andean-type magmatic arc onto all units north of the northern Liuling unit. Oblique subduction created Silurian-Devonian WNW-trending, sinistral transpressive wrench zones (e.g., Lo-Nan, Shang-Dan), and Late Permian-Early Triassic subduction reactivated them in dextral transpression (Lo-Nan, Shang-Xiang, Shang-Dan) and subducted the northern edge of the Yangtze craton. Exhumation of the cratonal edge formed the Wudang metamorphic core complex during dominantly pure shear crustal extension at ~230-235 Ma. Post-collisional south-directed shortening continued through the Early Jurassic. Cretaceous reactivation of the Qinling orogen started with NW-SE sinistral transtension, coeval with large-scale Early Cretaceous crustal extension and sinistral transtension in the northern Dabie Shan; it presumably resulted from the combined effects of the Siberia-Mongolia-Sino-Korean and Lhasa-West Burma-Qiangtang-Indochina collisions and Pacific subduction. Regional dextral wrenching was active within a NE-SW extensional regime between ~60 and 100 Ma. An Early Cretaceous Andean-type continental magmatic arc, with widespread Early Cretaceous magmatism and back-arc extension, was overprinted by shortening related to the collision of Yangtze-Indochina Block with the West Philippines Block. Strike-slip and normal faults associated with Eocene half-graben basins record Paleogene NNE-SSW contraction and WNW-ESE extension

  3. From Subsistence to Commercial Hunting: Technical Shift in Cynegetic Practices Among Southern Cameroon Forest Dwellers During the 20th Century

    Directory of Open Access Journals (Sweden)

    Edmond Dounias


    Full Text Available Tropical rainforest dwellers, who are currently engaged in bushmeat trade, used to track game for their own subsistence. We investigate the technical evolution over the past century of bushmeat procurement by the Fang, a group of southern Cameroon forest dwellers who are renowned for their extensive cynegetic expertise. This investigation consists of a diachronic approach to assess Fang hunting and trapping technology by comparing firsthand data on bushmeat procurement collected in the early 1990s with detailed descriptions recorded in the early 1900s among the same populations by the German anthropologist Günter Tessmann. Other archive sources bequeathed by explorers in the twilight of the 19th century are also exploited. The comparison conveys a more dynamic view of hunting practices following the greater involvement of the Fang hunters in the bushmeat trade. Historical sources remind us that projectile weapons were initially destined for warfare and that trapping, mobilizing a vast panel of modalities, was the prominent means to catch game for domestic consumption. Net hunting and crossbow hunting, which used to be typical Fang activities, are now exclusively conducted by Pygmies; spear hunting with hounds has become anecdotal. If a large range of trap mechanisms is still functional, effort is now focused on snares, elicited by the banalization of twisted wire cable. The legacy of other remaining models is left to children who carry out a didactic form of garden trapping. The major detrimental change is the use of firearms, which were initially adopted as a warfare prestige attribute before becoming the backbone instrument of bushmeat depletion. Revisiting the past provides useful lessons for improving current hunting management, through the promotion of garden hunting and wildlife farming, and the revitalization of a collective and cultural art of hunting as an alternative to indiscriminate overhunting by neophyte and increasingly

  4. Expression of the gene cluster associated with the Escherichia coli pilus adhesin K99. (United States)

    Lee, J H; Isaacson, R E


    The biogenesis of the pilus adhesin K99 is dependent on the expression of eight contiguous genes, fanA to fanH. Transposon mutants were prepared by using TnlacZ and TnphoA, and selected transposon mutants were used to measure expression of each K99 gene. Expression of the K99 genes is likely controlled at the transcription level, since in general, there were no differences between the results obtained with the two transposons. fanC was the most highly expressed, and fanD was expressed at very low levels. The expression of TnlacZ fusions in fanA and fanB fusions was high. Deletion of fanA, fanB, and part of fanC abolished the expression of fanD but had no effect on the distal genes fanE to fanH. To locate the DNA regions required for expression of fanE to fanH, deletion mutations were prepared and the effects on expression of fanE to fanH were determined. The deletion of a segment between fanD and fanE abolished fanE and fanF expression but did not affect fanG and fanH. The deletion of a portion of fanF (approximately 1 kb proximal to fanG) abolished the expression of fanG and fanH. These results indicate the presence of regulatory elements proximal to fanE and to fanG. Putative promoters were identified in these regions by DNA homology and by primer extension. A stem-loop structure that may act as a transcriptional attenuator of fanF was also found at the beginning of fanF. These data confirm our previous model of K99 transcriptional organization.

  6. The Significance of Witness Sensors for Mass Casualty Incidents and Epidemic Outbreaks. (United States)

    Pan, Chih-Long; Lin, Chih-Hao; Lin, Yan-Ren; Wen, Hsin-Yu; Wen, Jet-Chau


    Due to the increasing number of natural and man-made disasters, mass casualty incidents occur more often than ever before. As a result, health care providers need to adapt in order to cope with the overwhelming patient surge. To ensure quality and safety in health care, accurate information in pandemic disease control, death reduction, and health quality promotion should be highlighted. However, obtaining precise information in real time is an enormous challenge to all researchers of the field. In this paper, innovative strategies are presented to develop a sound information network using the concept of "witness sensors." To overcome the reliability and quality limitations of information obtained through social media, researchers must focus on developing solutions that secure the authenticity of social media messages, especially for matters related to health. To address this challenge, we introduce a novel concept based on the two elements of "witness" and "sensor." Witness sensors can be key players designated to minimize limitations to quality of information and to distinguish fact from fiction during critical events. In order to enhance health communication practices and deliver valid information to end users, the education and management of witness sensors should be further investigated, especially for implementation during mass casualty incidents and epidemic outbreaks. ©Chih-Long Pan, Chih-Hao Lin, Yan-Ren Lin, Hsin-Yu Wen, Jet-Chau Wen.

    Objective: The author presents the clinical diagnosis and treatment of one patient (Fang) with acute radiation sickness (ARS) without obvious history of radiation exposure, the therapeutic effect of simple isolation and administration of GM-CSF and the condition of other seven patients in this group. Methods: After collecting detailed history and chromosome aberration analysis of lymphocytes, a definite diagnosis of ARS was made and infectious diseases and poisoning were ruled out. Results: When Fang was recovered using GM-CSF and simple isolation, 143 rings plus dicentric aberrations were found in 300 lymphocytes at intermitotic phase, 0.4368 'R + Dic' aver agedly exist in every cell, the whole body dose was estimated to be 2.3 Gy. Thus, acute radiation sickness of moderate degree was ascertained. It was deduced that 3 other members in Fang's family died of ARS. Altogether about 100 victims were found. Conclusion: When a patient suffers suspicious burn (erythema, blistering) but without a history of contact of heat or fire and caustic chemicals and the patient has nausea, vomiting, epilation and decrease in white blood cells, the possibility of radiation exposure exists. If some patients with above manifestations are found in a same family, the radiation exposure may be more probable. A simple isolation ward can be set in an ordinary hospital and GM-CSF should be used to reduce the course

    External-beam PIXE has been applied for the determination of the elemental composition of ancient Chinese bronze artifacts. Characteristic x-ray spectra from the samples bombarded with protons of 3 MeV have been measured with a HPGe detector. At each sample three spots were irradiated per run. Results of measurements on three fragments of bronze drinking vessels and helmet of Chinese ancient Chou and Shang dynasties (17th-8th century B.C.) are presented. To check the analytical method, we have also made measurements on the elemental composition of some modern coins. The results are discussed. (author).

Although food intake is restricted by RYGB, drug absorption is also decreased. The purpose of this study was to develop novel self-nanoemulsifying drug delivery systems (SNEDDS for enhancing the oral delivery of silymarin, which has poor water solubility. The SNEDDS were characterized by size, zeta potential, droplet number, and morphology. A technique of RYGB was performed in Sprague-Dawley rats. SNEDDS were administered at a silymarin dose of 600 mg/kg in normal and RYGB rats for comparison with silymarin aqueous suspension and polyethylene glycol (PEG 400 solution. Plasma silibinin, the main active ingredient in silymarin, was chosen for estimating the pharmacokinetic parameters. SNEDDS diluted in simulated gastric fluid exhibited a droplet size of 190 nm with a spherical shape. The nanocarriers promoted silibinin availability via oral ingestion in RYGB rats by 2.5-fold and 1.5-fold compared to the suspension and PEG 400 solution, respectively. A significant double-peak concentration of silibinin was detected for RYGB rats receiving SNEDDS. Fluorescence

  1. The breeding behaviour, advertisement call and tadpole of Limnonectes dabanus (Anura: Dicroglossidae). (United States)

    Rowley, Jodi J L; Le, Duong Thi Thuy; Hoang, Huy Duc; Altig, Ronald


    Fanged frogs (Limnonectes) are a group of dicroglossid frogs from Asia that often have reversed sexual dimorphism with larger males. Limnonectes dabanus is a poorly known species of fanged frog from forested habitats in southern Vietnam and eastern Cambodia. Adult males exhibit an extreme degree of megacephaly and possess bizarre head ornamentation. L. dabanus breeds in shallow, non-flowing or very slow-flowing pools, puddles, and drainage ditches. Eggs are laid as a widely spaced array, and the larvae have a morphology typical of pond-dwelling tadpoles. Although males of the species lack vocal sacs, they produce a low-pitched (0.4-0.6 kHz), single-note advertisement call that sounds like a drop of water falling into water. Given the spacing of calling males, presence of multiple females near breeding sites, and reversed sexual dimorphism, the mating system of L. dabanus may be an example of resource-defense polygyny, and the massive head of the male is likely used in male combat.

  4. Randomised controlled trials of homeopathy in humans: characterising the research journal literature for systematic review. (United States)

    Mathie, Robert T; Hacke, Daniela; Clausen, Jürgen; Nicolai, Ton; Riley, David S; Fisher, Peter


    A new programme of systematic reviews of randomised controlled trials (RCTs) in homeopathy will distinguish important attributes of RCT records, including: placebo controlled versus other-than-placebo (OTP) controlled; individualised versus non-individualised homeopathy; peer-reviewed (PR) versus non peer-reviewed (NPR) sources. (a) To outline the methods used to search and categorise the RCT literature; (b) to report details of the records retrieved; (c) to compare our retrieved records with those reported in two previous systematic reviews (Linde et al., 1997; Shang et al., 2005). Ten major electronic databases were searched for records published up to the end of 2011. A record was accepted for subsequent systematic review if it was a substantive report of a clinical trial of homeopathic treatment or prophylaxis in humans, randomised and controlled, and published in a PR or NPR journal. 489 records were potentially eligible: 226 were rejected as non-journal, minor or repeat publications, or lacking randomisation and/or controls and/or a 'homeopathic' intervention; 263 (164 PR, 99 NPR) were acceptable for systematic review. The 263 accepted records comprised 217 (137 PR, 80 NPR) placebo-controlled RCTs, of which 121 were included by, 66 were published after, and 30 were potentially eligible for, but not listed by, Linde or Shang. The 137 PR records of placebo-controlled RCTs comprise 41 on individualised homeopathy and 96 on non-individualised homeopathy. Our findings clarify the RCT literature in homeopathy. The 263 accepted journal papers will be the basis for our forthcoming programme of systematic reviews. Copyright © 2012 The Faculty of Homeopathy. Published by Elsevier Ltd. All rights reserved.

    To investigate the effects of blueberry on the apoptosis, expression of Bcl-2 and Bax in rat hepatic stellate cell (HSC-T6). 10% blueberry serum at low, middle and high dose, 10% Fu-Fang-Bie-Jia-Ruan-Gan tablet serum and 10% saline serum were prepared by method of serum pharmacology. Subcultured HSC-T6 was divided into saline serum control group, blueberry serum at low, middle, high dose and Fu-Fang-Bie-Jia-Ruan-Gan tablet serum group, and then was respectively incubated at different dose of 10% blueberry serum, 10% Fu-Fang-Bie-Jia-Ruan-Gan tablet serum and 10% saline serum for 72 hours.Apoptosis of HSC-T6 was detected using flow cytometry with annexin V FITC/PI double staining. The expression of Bcl-2 and Bax in HSC-T6 were examined using immunocytochemistry and Western blotting, respectively. There was no significant difference for HSC-T6 Bax protein expression in the low, middle and high dose blueberry serum groups, compared with saline serum control group, respectively.In the high-dose blueberry serum group HSC-T6 early and total apoptosis rate increased significantly compared with the saline serum control group (5.55% ± 0.98% vs 2.53% ± 0.46%, 7.01% ± 1.05% vs 2.96% ± 0.81%, both Pblueberry serum group showed no significant difference with the saline serum control group. Blueberry can induce HSC-T6 apoptosis by down-regulating Bcl-2 expression and decreasing the ratio of Bcl-2/Bax in HSC-T6 cells, so it may have potential interference effects on hepatic fibrosis.

    It is demonstrated that the pitch angle integrals in the transport fluxes in the ν regime calculated in K. C. Shang [Phys. Plasmas 10, 1443 (2003)] are divergent as the trapped-circulating boundary is approached. Here, ν is the collision frequency. The origin of this divergence results from the logarithmic dependence in the bounce averaged radial drift velocity. A collisional boundary layer analysis is developed to remove the singularity. The resultant pitch angle integrals now include not only the original physics of the ν regime but also the boundary layer physics. The transport fluxes, caused by the particles inside the boundary layer, scale as √(ν)

The tunable delivery function can be paired with an apoptosis biosensor based on the same fiber-optic configuration for providing real-time evaluation of chemotherapy efficacy in vivo to perform as a personalized chemotherapy system. The pattern of topical release triggered by laser excitation conveyed through optical fibers was monitored by the increase in fluorescence resulting from the dilution of self-quenching (75 mM fluorescein encapsulated in liposomes. In in vitro studies (in 37°C phosphate buffer saline, the AuNP-embedded liposomes showed a more efficient triggered release (74.53%±1.63% in 40 minutes than traditional temperature-responsive liposomes without AuNPs (14.53%±3.17% or AuNP-liposomes without excitation (21.92%±2.08% by spectroscopic measurements. Using the mouse xenograft studies, we first demonstrated that the encapsulation of fluorescein in liposomes resulted in a more substantial content retention (81% in the tumor than for free fluorophores (14% at 120 minutes after administration from in vivo fluorescence imaging. Furthermore, the preliminary results also suggested the tunable release capability of the system by demonstrating consecutive triggered releases with fiber-optic guided laser excitation.

This study was further designed to evaluate the effects of nanoparticles prepared from the water extract of Gusuibu (WEG on osteoblast survival and maturation. Primary osteoblasts were exposed to 1, 10, 100, and 1000 µg/mL nanoparticles of WEG (nWEG for 24, 48, and 72 hours did not affect morphologies, viability, or apoptosis of osteoblasts. In comparison, treatment of osteoblasts with 1000 µg/mL WEG for 72 hours decreased cell viability and induced DNA fragmentation and cell apoptosis. nWEG had better antioxidant bioactivity in protecting osteoblasts from oxidative and nitrosative stress-induced apoptosis than WEG. In addition, nWEG stimulated greater osteoblast maturation than did WEG. Therefore, this study shows that WEG nanoparticles are safer to primary osteoblasts than are normal-sized products, and may promote better bone healing by protecting osteoblasts from apoptotic insults, and by promoting osteogenic maturation.Keywords: Gusuibu, nanoparticles, cell protection, osteoblast maturation

Alveolar macrophages (AMs from patients with COPD release a greater amount of matrix metalloproteinase (MMP-9. We hypothesized that the imbalance between MMP-9 and tissue inhibitor of metalloproteinase-1 (TIMP-1 is related to AHR in smokers.Patients and methods: Healthy smokers with AHR (AHR + S or smokers without AHR (AHR - S; divided according to a methacholine challenge test and nonsmokers without AHR (AHR - NS were enrolled. Spirometry was performed during enrollment and repeated after 5 years. Initially, AMs recovered from bronchoalveolar lavage (BAL fluid were cultured in the presence of p38 mitogen-activated protein kinase (MAPK inhibitor (SB203580, MAPK kinase (MEK 1/2 (the MEK of extracellular signal-regulated kinase [ERK] inhibitor, PD98059, or medium alone for 24 h. The release of MMP-9 and TIMP-1 in culture supernatants was measured by enzyme-linked immunosorbent assay.Results: A greater reduction in forced expiratory volume in 1 s (FEV1/forced vital capacity (FVC, FEV1 (as a percentage of the predicted value [%pred], and maximal mid-expiratory flow (MMEF was observed among AHR + S in the 5-year period. There was a higher proportion of neutrophils and a lower proportion of AMs in BAL fluid recovered from AHR + S. Compared to AMs from AHR - NS and AHR - S, AMs from nonsmokers with AHR (AHR + NS released more MMP-9 and less TIMP-1, with an increase in MMP-9/TIMP-1 ratios. The MMP-9/TIMP-1 ratio in smokers

However, few studies have been performed to explore the risk factors for pneumonia development in patients with PD.Methods: We conducted a nationwide population-based cohort study of patients with PD to identify the risk factors for these patients developing pneumonia. Participants with newly diagnosed PD between 2000 and 2009 were enrolled from the 2000–2010 National Health Insurance Research Database in Taiwan. We compared patients with PD with an incidence of hospitalization with pneumonia vs those without, and Cox proportional hazard models were used to estimate the risk of pneumonia.Results: Of the 2,001 enrolled patients (mean follow-up duration 5.8 years, range: 2.7–14.7 years, 381 (19.0% had an incidence of hospitalization with pneumonia during the study period. Multivariate Cox proportional hazards analysis identified older age group (≥80 years of age, hazard ratio [HR] =3.15 [95% confidence interval 2.32–4.28], male sex (HR =1.59 [1.29–1.96], certain geographic regions (northern, HR =1.36 [1.04–1.78], southern and eastern, HR =1.40 [1.05–1.88], rural areas (HR =1.34 [1.05–1.72], chronic heart

  12. Grooves to tubes: evolution of the venom delivery system in a Late Triassic "reptile" (United States)

    Mitchell, Jonathan S.; Heckert, Andrew B.; Sues, Hans-Dieter


    Venom delivery systems occur in a wide range of extant and fossil vertebrates and are primarily based on oral adaptations. Teeth range from unmodified (Komodo dragons) to highly specialized fangs similar to hypodermic needles (protero- and solenoglyphous snakes). Developmental biologists have documented evidence for an infolding pathway of fang evolution, where the groove folds over to create the more derived condition. However, the oldest known members of venomous clades retain the same condition as their extant relatives, resulting in no fossil evidence for the transition. Based on a comparison of previously known specimens with newly discovered teeth from North Carolina, we describe a new species of the Late Triassic archosauriform Uatchitodon and provide detailed analyses that provide evidence for both venom conduction and document a complete structural series from shallow grooves to fully enclosed tubular canals. While known only from teeth, Uatchitodon is highly diagnostic in possessing compound serrations and for having two venom canals on each tooth in the dentition. Further, although not a snake, Uatchitodon sheds light on the evolutionary trajectory of venom delivery systems in amniotes and provide solid evidence for venom conduction in archosaur-line diapsids.

Developing new strategies to improve the osteoinductive activity of bone graft substitutes is both critical and practical for clinical application. Previously, we developed novel simvastatin-encapsulating poly(lactic-co-glycolic acid microspheres (SIM/PLGA that slowly release simvastatin and enhance fracture healing. In this study, we combined SIM/PLGA with a rapidly absorbable calcium sulfate (CS bone substitute and studied the effect on bone healing in critical-sized calvarial bone defects in a rat model. The cytotoxicity and cytocompatibility of this combination was tested in vitro using lactate dehydrogenase leakage and a cell attachment assay, respectively. Combination treatment with SIM/PLGA and the CS bone substitute had no cytotoxic effect on bone marrow stem cells. Compared with the control, cell adhesion was substantially enhanced following combination treatment with SIM/PLGA and the CS bone substitute. In vivo, implantation of the combination bone substitute promoted healing of critical-sized calvarial bone defects in rats; furthermore, production of bone morphogenetic protein-2 and neovascularization were enhanced in the area of the defect. In summary, the combination of SIM/PLGA and a CS bone substitute has osteoconductive and osteoinductive properties, indicating that it could be used for regeneration

    This short paragraph tries to identify the camel diseases compiled in the old chinese text according to modern veterinary terms. Due to the specific terminology of the camel treatise and its overall scarce symptomatology the diseases are difficult to evaluate. The majority of them obviously deal with acute infectious diseases which manifest themselves under such symptoms as high fever, depression, anorexia, cachexia, diarrhoea, general weakness, etc. But there are some diseases and ailments which can be interpreted in modern terms my means of the symptoms, descriptions and cures, e.g. mange, paradontosis and wry-neck syndrome.

  18. Investigating the tool marks on oracle bones inscriptions from the Yinxu site (ca., 1319-1046 BC), Henan province, China. (United States)

    Zhao, Xiaolong; Tang, Jigen; Gu, Zhou; Shi, Jilong; Yang, Yimin; Wang, Changsui


    Oracle Bone Inscriptions in the Shang dynasty (1600-1046 BC) are the earliest well-developed writing forms of the Chinese character system, and their carving techniques have not been studied by tool marks analysis with microscopy. In this study, a digital microscope with three-dimensional surface reconstruction based on extended depth of focus technology was used to investigate tool marks on the surface of four pieces of oracle bones excavated at the eastern area of Huayuanzhuang, Yinxu site(ca., 1319-1046 BC), the last capital of the Shang dynasty, Henan province, China. The results show that there were two procedures to carve the characters on the analyzed tortoise shells. The first procedure was direct carving. The second was "outlining design," which means to engrave a formal character after engraving a draft with a pointed tool. Most of the strokes developed by an engraver do not overlap the smaller draft, which implies that the outlining design would be a sound way to avoid errors such as wrong and missing characters. The strokes of these characters have different shape at two ends and variations on width and depth of the grooves. Moreover, the bottom of the grooves is always rugged. Thus, the use of rotary wheel-cutting tools could be ruled out. In most cases, the starting points of the strokes are round or flat while the finishing points are always pointed. Moreover, the strokes should be engraved from top to bottom. When vertical or horizontal strokes had been engraved, the shell would be turned about 90 degrees to engrave the crossed strokes from top to bottom. There was no preferred order to engrave vertical or horizontal strokes. Since both sides of the grooves of the characters are neat and there exists no unorganized tool marks, then it is suggested that some sharp tools had been used for engraving characters on the shells.

    Full Text Available The helmet appeared in the steppes of Eurasia at the end of the second mill. BC. The helmets were cast and seem to follow Chinese helmets of the Shang-Yin time. This type of helmet reached eastern Europe in the first centuries of the first mill. BC. A new development was the armoured cap of felt with iron casted scales.It was developed by the Skythians under the impression of the Assyrian scale armour which they met during their invasion in Near East. Three Assyrian pointed helmets were found in northern Caucasia and might be booty or bought by the Cimmerians or the Skythians in the Seventh or sixth century BC. During the fifth and fourth centuries the Greeks sold several types of helmets to the Skythians. Thrakian helmets might have been won during wars on the Balkans. Celtic helmets found at several sites might have been imported via Italy -or are left by Celtic mercenaries of the Pontos kings.

Este tipo de casco alcanzó Europa oriental durante los primeros siglos del primer milenio a.C. Un nuevo desarrollo fue el capacete blindado de fieltro con escamas de hierro. Fue creado por los escitas bajo la influencia de las corazas asirias de escamas que encontraron durante sus incursiones en el Próximo Oriente. Tres cascos asirios apuntados han sido hallados en el norte del Cáucaso y podrían ser botín o adquisiciones de los Cimerios o los escitas durante los siglos VII-VI a.C. Durante los siglos V-IV a.C. los griegos vendieron diversos tipos de cascos a los Escitas. Cascos tracios pueden haber sido capturados durante campañas en los Balcanes.

    Full Text Available Subsynchronous oscillation (SSO usually caused by series compensation, power system stabilizer (PSS, high voltage direct current transmission (HVDC and other power electronic equipment, which will affect the safe operation of generator shafting even the system. It is very important to identify the modal parameters of SSO to take effective control strategies as well. Since the identification accuracy of traditional methods are not high enough, the stochastic subspace identification (SSI method is proposed to improve the identification accuracy of subsynchronous oscillation modal. The stochastic subspace identification method was compared with the other two methods on subsynchronous oscillation IEEE benchmark model and Xiang-Shang HVDC system model, the simulation results show that the stochastic subspace identification method has the advantages of high identification precision, high operation efficiency and strong ability of anti-noise.

    Energy Technology Data Exchange (ETDEWEB)

    Shinkai, A [Kyushu University, Fukuoka (Japan). Faculty of Engineering


    Designing a vessel to sail oceans for an extended period of time requires statistical estimation on different hull responses to waves. To meet the requirement, it is necessary to accurately identify hydrographic conditions (particularly waves) which are considered to be encountered by the vessel. This paper makes clear the statistical characteristics of the wave statistics table presented by Fang et al, and compares them with other processes for discussion. This statistics collection is based on data collected in China, Hong Kong and Japan, including those collected in the Sea of Japan, the Yellow Sea, the North Sea, the East China Sea and the South China Sea. It was found that these data provide results slightly lower than the long-term estimation values derived from data of the global wave statistics (GWS) prepared by Hogben et al. The cause for this was found attributable to the format of the statistical data, especially setting of wave height classes. However, since the data provided by Fang et al include items of detailed information on small sea areas near the Chinese coast lines, the data are thought to provide useful information source in investigating long-term hull response characteristics relative to spatial spread of the sea areas in the North-west Pacific Ocean. 15 refs., 5 figs., 2 tabs.

  7. Complementary microanalysis of Zn, Mn and Fe in the chelicera of spiders and scorpions using scanning MeV-ion and electron microprobes

    International Nuclear Information System (INIS)

    Schofield, R.; Lefevre, H.; Shaffer, M.


    Energy-loss scanning transmission ion microscopy (ELSTIM or just STIM), PIXE and electron microprobe techniques are used to investigate certain minor element accumulations in a few spiders and scorpions. STIM and PIXE are used to survey the unsectioned specimens, while electron microprobe techniques are used for higher resolution investigations of several sections of the specimens. Concentration values measured using STIM and PIXE are found to be in satisfactory agreement with those measured using electron probe microanalysis. A garden spider Araneous diadematus is found to contain high concentrations of zinc in a thin layer near the surface of its fangs (reaching 23% of dry weight), and manganese in its marginal teeth (about 5% of dry weight). A wolf spider Alopecosa kochi is found to have similar concentrations of zinc in a layer near the surface of it's fang, and concentrations of manganese reaching 1.5% in a layer beneath the zinc containing layer. A scorpion Centruroides sp. is found to contain high concentrations of iron (reaching 8%) and zinc (reaching 24%) in the tips of teeth on the cheliceral fingers, and manganese (about 5%) in the stinger. The hypothesis that these elements simply harden the cuticle does not appear to explain their segregation patterns. (orig.)

  8. [A study of the sexual art of having intercourse with several young virgins in traditional Chinese medicine]. (United States)

    Yan, Shanzhao


    The emergency treatments for the damage and bleeding of the vagina, and the sharp pubic pain of young virgins which were caused occurred by the sexual art, were recorded in traditional medicine books, such as the "Ji yan fang" and others. It is a fact that in ancient China some people used the sexual art of having intercourse with several young virgins at the same time in order to increase their health and keep perpetual youth and longevity. The famous traditional general-medical book, "qian jin yao fang" recommended that method to rich persons too. It is supposed that the beginning of the sexual art of having intercourse with several young virgins traces back to the times of Emperor Hanwu , but it seems to have disappeared from the historical stage in the Song period. On the other hand, the criticisms from the traditional medicine books and the secret languages of internal alchemy used for the Taoist sacred books show that the sexual art of having intercourse with several young virgins was still going on behind the scene in the Ming and Qing periods. Even if we consider the historical changes of ethics and mortality, we now cannot but criticize this behavior of abusing juveniles for the sexual art.

  2. Research on evaluation methods for water regulation ability of dams in the Huai River Basin (United States)

    Shan, G. H.; Lv, S. F.; Ma, K.


    Water environment protection is a global and urgent problem that requires correct and precise evaluation. Evaluation methods have been studied for many years; however, there is a lack of research on the methods of assessing the water regulation ability of dams. Currently, evaluating the ability of dams has become a practical and significant research orientation because of the global water crisis, and the lack of effective ways to manage a dam's regulation ability has only compounded this. This paper firstly constructs seven evaluation factors and then develops two evaluation approaches to implement the factors according to the features of the problem. Dams of the Yin Shang ecological control section in the Huai He River basin are selected as an example to demonstrate the method. The results show that the evaluation approaches can produce better and more practical suggestions for dam managers.

Several terms are available for this type of love song in Amdo Tibetan. La gzhas is the most common term for such songs in written Tibetan, la meaning 'mountain pass' and gzhas 'song'. In oral Amdo Tibetan, it is la-ye , a homophone of the literary term. Ri glu literally means mountain song, and this term matches the Chinese term for love songs, shan'ge.

Nevertheless, the challenge remains as to whether this therapeutic effect is attributable to the combination of a radioisotope with chemotherapeutics. The goal of this study was to investigate the pharmacokinetics, biodistribution, and correlation of Indium-111 radioactivity and vinorelbine concentration in the 111In-VNB-liposome.Methods: The VNB-liposome and 111In-VNB-liposome were administered to rats. Blood, liver, and spleen tissue were collected to determine the distribution profile of the 111In-VNB-liposome. A liquid chromatography tandem mass spectrometry system and gamma counter were used to analyze the concentration of vinorelbine and radioactivity of Indium-111.Results: High uptake of the 111In-VNB-liposome in the liver and spleen demonstrated the properties of a nanosized drug delivery system. Linear regression showed a good correlation (r = 0.97 between Indium-111 radioactivity and vinorelbine concentration in the plasma of rats administered the 111In-VNB-liposome.Conclusion: A significant positive correlation between the pharmacokinetics and biodistribution of 111Indium radioactivity and vinorelbine in blood, spleen

    Full Text Available La historia del jardín en la cultura china se remonta a la historia de las dinastías Shang y Zhou y continúa a lo largo de las dinastías Qin, Han, Tang, Song, Yuan, Ming y Qing hasta la llegada de la República China y la República Popular de China. Los valores artísticos y paisajísticos del jardín en esta cultura se desarrollaron de forma paralela a la historia de la nación y tuvieron una influencia directa sobre la arquitectura doméstica y sobre el jardín de naciones cercanas como Japón. Sus influencias se reflejaron en teorías como el Fengshui y las leyes geománticas y generaron a lo largo de los siglos valores compositivos propios del jardín chino. La conclusion de esta investigación consiste en una asimilación de lo estudiado y en detallar los aspectos compositivos y de diseño, tales como el centro, el límite, el element de la montaña, el vacío, el agua, o el teatro, entre otros. ABSTRACT: This essay starts with a brief description of the history of the garden in the East and introduces the reader into the Chinese culture starting with the Shang and Zhou Dynasties and continuing with the historical development through the Qin, Han, Tang, Song, Yuan, Ming and Qing dynasties and the arrival of the Republic of China and the People’s Republic of China. In this essay the artistic and landscape values of Chinese culture are described alongside the history of the garden and the influences on the Japanese garden they have had from ancient times until today. These are explained alongside the art of Fengshui, geomantic laws and the main elements that compose the Chinese garden. The conclusion entails a brief assimilation of what has been deduced from the main study. In this part of the essay the compositive and design aspects of the Chinese garden are described, aspects such as centre, limit, the element of the mountain, emptiness, water, and the theatre, among other.

  14. Izumo and the East Asian Bronze Culture%出云与东亚的青铜文化

    Institute of Scientific and Technical Information of China (English)



    The origin of bronzes in Yayoi Japan can be traced to their counterparts in Xia-Shang-Zhou China. It must have happened that ancient Chinese bronze weapons and small bells used aspractical implements were first spread into Japan through northeastern China and the Korean Peninsulaand then developed gradually into bronzes exclusively for sacrificial use. Among the bronzes unearthed inbatches from hoards in the Izumo area within the coastland of the Sea of Japan, the spearheads may havebeen made in the north of Kyushu, the small bells must have come from the Kinai region, and the over300 swords were probably local products. The repeated discovery of Yayoi bronze hoards in the Izumoarea suggests that this region was absolutely not an unpopulated land. On the contrary, as a very im-portant district, it should be fully affirmed to have played a considerable role in the development of an-cient Japanese history.

  19. Regulation of gene expression by yoga, meditation and related practices: a review of recent studies. (United States)

    Saatcioglu, Fahri


    Integrative medicine (IM) approaches have gained significant interest in recent years to provide a solution for the health care challenges we face today. Yogic cognitive-behavioral practices are among the most widely used IM approaches and include diverse practices such as yoga asanas, meditation, breathing exercises, Qi Gong, Tai Chi Chih, and various others. Studies to date suggest that these yogic/meditative practices have significant positive effects on the mind-body system and thereby can increase wellness and support the healing process from disease. Previous work has provided evidence for both psychological and physiological effects of these practices; however, the mechanisms of these effects, especially at the molecular level, have largely been missing. Three recent studies started to provide some of this information through gene expression profiling in circulating immune cells, which support the hypothesis that yogic/meditative practices have a measurable effect at the molecular level. These studies are reviewed herein and some future perspectives are considered. Copyright © 2012 Elsevier B.V. All rights reserved.

  1. A Review and Database of Snake Venom Proteomes. (United States)

    Tasoulis, Theo; Isbister, Geoffrey K


    Advances in the last decade combining transcriptomics with established proteomics methods have made possible rapid identification and quantification of protein families in snake venoms. Although over 100 studies have been published, the value of this information is increased when it is collated, allowing rapid assimilation and evaluation of evolutionary trends, geographical variation, and possible medical implications. This review brings together all compositional studies of snake venom proteomes published in the last decade. Compositional studies were identified for 132 snake species: 42 from 360 (12%) Elapidae (elapids), 20 from 101 (20%) Viperinae (true vipers), 65 from 239 (27%) Crotalinae (pit vipers), and five species of non-front-fanged snakes. Approximately 90% of their total venom composition consisted of eight protein families for elapids, 11 protein families for viperines and ten protein families for crotalines. There were four dominant protein families: phospholipase A₂s (the most common across all front-fanged snakes), metalloproteases, serine proteases and three-finger toxins. There were six secondary protein families: cysteine-rich secretory proteins, l-amino acid oxidases, kunitz peptides, C-type lectins/snaclecs, disintegrins and natriuretic peptides. Elapid venoms contained mostly three-finger toxins and phospholipase A₂s and viper venoms metalloproteases, phospholipase A₂s and serine proteases. Although 63 protein families were identified, more than half were present in <5% of snake species studied and always in low abundance. The importance of these minor component proteins remains unknown.

  2. Fatigue-Arrestor Bolts (United States)

    Onstott, Joseph W.; Gilster, Mark; Rodriguez, Sergio; Larson, John E.; Wickham, Mark D.; Schoonover, Kevin E.


    Bolts that arrest (or, more precisely, retard) onset of fatigue cracking caused by inelastic strains developed. Specifically developed to be installed in flange holes of unrestrained rocket engine nozzle. Fanges sometimes used to bolt nozzle to test stand; however, when rocket engine operated without this restraint, region around bolt holes experience severe inelastic strains causing fatigue cracking. Interference fits introduce compressive preloads that retard fatigue by reducing ranges of strains. Principle of these fatigue-arrestor bolts also applicable to holes in plates made of other materials and/or used for different purposes.

  8. Quantum cosmology of classically constrained gravity

    International Nuclear Information System (INIS)

    Gabadadze, Gregory; Shang Yanwen


    In [G. Gabadadze, Y. Shang, hep-th/0506040] we discussed a classically constrained model of gravity. This theory contains known solutions of General Relativity (GR), and admits solutions that are absent in GR. Here we study cosmological implications of some of these new solutions. We show that a spatially-flat de Sitter universe can be created from 'nothing'. This universe has boundaries, and its total energy equals to zero. Although the probability to create such a universe is exponentially suppressed, it favors initial conditions suitable for inflation. Then we discuss a finite-energy solution with a nonzero cosmological constant and zero space-time curvature. There is no tunneling suppression to fluctuate into this state. We show that for a positive cosmological constant this state is unstable-it can rapidly transition to a de Sitter universe providing a new unsuppressed channel for inflation. For a negative cosmological constant the space-time flat solutions is stable.

  9. Style and Classification in the History of Art

    Directory of Open Access Journals (Sweden)

    Matthew Martin


    Full Text Available Review of: Robert Bagley, Max Loehr and the Study of Chinese Bronzes. Style and Classification in the History of Art, Ithaca, NY: Cornell East Asia Series, 2008. Robert Bagley’s monograph uses his mentor Max Loehr’s work on Shang period Chinese bronzes as the starting point for a critical examination of issues surrounding the art historical notion of ‘style’. Bagley critiques the tendency by much art history to the reification of ‘style’, an intellectual construction, and dismisses the idea that ‘style’ can somehow embody the characteristics of a ‘Zeitgeist’. Bagley argues for the independence of artistic and aesthetic concerns in explaining developments in the formal characteristics of objects of material culture, without the need to appeal to external forces such as literary sources or a symbolic system. We must take seriously, Bagley suggests, that visual effect, independent of other considerations, was a characteristic consciously pursued by artists of the past.

  10. Designing two-in-one antibodies. (United States)

    Valladares, Ignacio Garcia; Espinoza, Luis R


    Evaluation of: Bostrom J, Shang-Fan Y, Kan D et al.: Variants of the antibody Herceptin that interact with HER2 and VEGF at the antigen binding site. Science 323, 1610-1614 (2009). The longstanding held notion that one antibody equals one antigen and, hence, one function has been challenged in recent years. Improved technology in antibody production, especially the accumulation of sequence data of immunoglobulin genes and the advent of PCR have made it possible to clone antibody gene repertoires. The current paper provides further challenge to the notion of one antibody = one antigen by developing 'two-in-one' antibodies with an antigen-binding site that binds two distinct proteins with high affinity. A therapeutic variant antibody of Herceptin (Genentech, CA, USA) was isolated that binds the human EGF receptor (HER)2 and also to VEGF. This development may represent a breakthrough discovery and may have significant implications in the therapy of malignant, infectious, allergic and autoimmune disorders.

  11. Experimental Language Deconstructing Patriarchal Discourse in Ntozake Shange’s for colored girls who have considered suicide/ when the rainbow is enuf

    Directory of Open Access Journals (Sweden)

    Tellini Silvia Mara


    Full Text Available By sharing the experiences of women and the black community of her time, represented as a journey towards womanhood on stage, Afro- American playwright Ntozake Shange deconstructs the patriarchal structure of language, by pushing the boundaries of genres as she assembles prose, poetry and stage performance in a “choreopoem” capable of empowering and liberating the trajectories of the represented black women. The present study explores the semiotic and linguistic deconstructions of the patriarchal ideology in for colored girls who have considered suicide/ when the rainbow is enuf, aiming at a discussion of the author’s experimentalism with language outside instituted discursive paradigms regarding women. Considering that the concept of the liberation of the individual is strongly historicized in the play, the characters of the seven ladies are focalized as being tightly related to the feminist movement in North America in the seventies. Furthermore, the implications of ideological impositions and limited roles for women in society are analyzed.

    羅明通 Ming-Tung Lo


    Full Text Available 思想與表達之區別及合併攸關電腦程式侵權之判斷,惟表達是否包含非文字之結構?電腦程式之非文字成分是否屬於表達?思想與表達之區別原則適用於著作之非文字成分之結構時,判斷之基準為何?電腦程式之結構在何種情況因思想與表達之合併而不受著作權法保護?電腦程式之著作權侵權判之步驟為何?我國司法實務見解不一。本文即以最高法院94年度台上字第1530號刑事判決為基礎,分析美國著作權法對非文字成分之思想與表達區別之基準,再解析美國著作權法權威案例Altai案三步驟測試法之精義,並闡釋思想與表達區分及合併在兩個案例中運用之精微。結論則比較研析我國司法實務爭點之所在,釐清相關疑義,期使讀者對此問題之觀察臻於全面。 The dichotomy and merger between idea and expression is highly related to the judgment of the infringement of computer program. Shall the expression be limited to literal element of work? Can the non-literal element of computer program possibly be categorized as expression? If it is possible, then what is the criterion for drawing such a distinction? Under what kind of circumstances, can the expression be regarded s having been merged with idea? And what is the process to make such a judgment of infringement? In this regard Taiwan judicial decisions have submitted different opinions. Based upon Supreme Court Criminal Judgment No. 94-Tai-Shang-Tze-1530, 2005, this article analyze the criterion for the distinction between idea and expression, and then analyze the contents of the three-step procedure by which judges in Altai applied the principle of the dichotomy and merger between idea and expression to decide the infringement. Finally, in conclusion, this article makes some comments on relevant mentioned above cases, serving as a reference for readers to have a panoramic observation.

  13. Development of interactive graphic user interfaces for modeling reaction-based biogeochemical processes in batch systems with BIOGEOCHEM (United States)

    Chang, C.; Li, M.; Yeh, G.


    The BIOGEOCHEM numerical model (Yeh and Fang, 2002; Fang et al., 2003) was developed with FORTRAN for simulating reaction-based geochemical and biochemical processes with mixed equilibrium and kinetic reactions in batch systems. A complete suite of reactions including aqueous complexation, adsorption/desorption, ion-exchange, redox, precipitation/dissolution, acid-base reactions, and microbial mediated reactions were embodied in this unique modeling tool. Any reaction can be treated as fast/equilibrium or slow/kinetic reaction. An equilibrium reaction is modeled with an implicit finite rate governed by a mass action equilibrium equation or by a user-specified algebraic equation. A kinetic reaction is modeled with an explicit finite rate with an elementary rate, microbial mediated enzymatic kinetics, or a user-specified rate equation. None of the existing models has encompassed this wide array of scopes. To ease the input/output learning curve using the unique feature of BIOGEOCHEM, an interactive graphic user interface was developed with the Microsoft Visual Studio and .Net tools. Several user-friendly features, such as pop-up help windows, typo warning messages, and on-screen input hints, were implemented, which are robust. All input data can be real-time viewed and automated to conform with the input file format of BIOGEOCHEM. A post-processor for graphic visualizations of simulated results was also embedded for immediate demonstrations. By following data input windows step by step, errorless BIOGEOCHEM input files can be created even if users have little prior experiences in FORTRAN. With this user-friendly interface, the time effort to conduct simulations with BIOGEOCHEM can be greatly reduced.

  14. Cenozoic uplift of the Tibetan Plateau: Evidence from the tectonic–sedimentary evolution of the western Qaidam Basin

    Directory of Open Access Journals (Sweden)

    Yadong Wang


    Full Text Available Geologists agree that the collision of the Indian and Asian plates caused uplift of the Tibet Plateau. However, controversy still exists regarding the modes and mechanisms of the Tibetan Plateau uplift. Geology has recorded this uplift well in the Qaidam Basin. This paper analyzes the tectonic and sedimentary evolution of the western Qaidam Basin using sub-surface seismic and drill data. The Cenozoic intensity and history of deformation in the Qaidam Basin have been reconstructed based on the tectonic developments, faults growth index, sedimentary facies variations, and the migration of the depositional depressions. The changes in the sedimentary facies show that lakes in the western Qaidam Basin had gone from inflow to still water deposition to withdrawal. Tectonic movements controlled deposition in various depressions, and the depressions gradually shifted southeastward. In addition, the morphology of the surface structures in the western Qaidam Basin shows that the Cenozoic tectonic movements controlled the evolution of the Basin and divided it into (a the southern fault terrace zone, (b a central Yingxiongling orogenic belt, and (c the northern fold-thrust belt; divided by the XI fault (Youshi fault and Youbei fault, respectively. The field data indicate that the western Qaidam Basin formed in a Cenozoic compressive tectonic environment caused by the India–Asia plate collision. Further, the Basin experienced two phases of intensive tectonic deformation. The first phase occurred during the Middle Eocene–Early Miocene (Xia Ganchaigou Fm. and Shang Ganchaigou Fm., 43.8–22 Ma, and peaked in the Early Oligocene (Upper Xia Ganchaigou Fm., 31.5 Ma. The second phase occurred between the Middle Miocene and the Present (Shang Youshashan Fm. and Qigequan Fm., 14.9–0 Ma, and was stronger than the first phase. The tectonic–sedimentary evolution and the orientation of surface structures in the western Qaidam Basin resulted from the Tibetan

  2. Chemical characteristics and anti-proliferation activities of Ganoderma tsugae polysaccharides. (United States)

    Chien, Rao-Chi; Yen, Ming-Tsung; Tseng, Yu-Hsiu; Mau, Jeng-Leun


    Polysaccharides were extracted by hot-water and hot-alkali from four forms of Ganoderma tsugae including mature and baby Ling chih, mycelium and filtrate. Different profiles of proximate composition and monosaccharide constituents, and element contents were found in the extracted polysaccharides from different extractions and different forms. The molecular weight distributions of polysaccharides were 2.8×10(4)-6.5×10(5)Da and their infrared spectra were comparable. The hot-alkali extracted polysaccharides exhibited better anti-proliferation on IMR32 cells than the hot-water extracted polysaccharides, which were in turn more effective than the hot-water extracts. Besides, most hot-water extracts and both extracted polysaccharides exhibited an anti-proliferation effect on Hep G2 cells. However, the hot-water extracts showed less effective in anti-proliferation of IMR32 and Hep G2 cells. Based on the anti-tumor effects, both polysaccharides could be prepared for use in the formulation of nutraceuticals and functional foods. Copyright © 2015 Elsevier Ltd. All rights reserved.

  5. Probiotics Supplementation Therapy for Pathological Neonatal Jaundice: A Systematic Review and Meta-Analysis. (United States)

    Chen, Zhe; Zhang, Lingli; Zeng, Linan; Yang, Xiaoyan; Jiang, Lucan; Gui, Ge; Zhang, Zuojie


    Background: Neonatal jaundice is a relatively prevalent disease and affects approximately 2.4-15% newborns. Probiotics supplementation therapy could assist to improve the recovery of neonatal jaundice, through enhancing immunity mainly by regulating bacterial colonies. However, there is limited evidence regarding the effect of probiotics on bilirubin level in neonates. Therefore, this study aims at systematically evaluating the efficacy and safety of probiotics supplement therapy for pathological neonatal jaundice. Methods: Databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wan Fang Database (Wan Fang), Chinese Biomedical Literature Database (CBM), VIP Database for Chinese Technical Periodicals (VIP) were searched and the deadline is December 2016. Randomized controlled trials (RCTs) of probiotics supplementation for pathological neonatal jaundice in publications were extracted by two reviewers. The cochrane tool was applied to assessing the risk of bias of the trials. The extracted information of RCTs should include efficacy rate, serum total bilirubin level, time of jaundice fading, duration of phototherapy, duration of hospitalization, adverse reactions. The main outcomes of the trials were analyzed by Review Manager 5.3 software. The relative risks (RR) or mean difference (MD) with a 95% confidence interval (CI) was used to measure the effect. Results: 13 RCTs involving 1067 neonatal with jaundice were included in the meta-analysis. Probiotics supplementation treatment showed efficacy [RR: 1.19, 95% CI (1.12, 1.26), P jaundice. It not only decreased the total serum bilirubin level after 3day [MD: -18.05, 95% CI (-25.51, -10.58), P jaundice fading [MD: -1.91, 95% CI (-2.06, -1.75), P probiotics supplementation therapy is an effective and safe treatment for pathological neonatal jaundice.

  6. Individual taper models for natural cedar and Taurus fir mixed stands of Bucak Region, Turkey

    Ramazan Özçelik


    Full Text Available In this study, we assessed the performance of different types of taper equations for predicting tree diameters at specific heights and total stem volumes for mixed stands of Taurus cedar (Cedrus libani A. Rich. and Taurus fir (Abies cilicica Carr.. We used data from mixed stands containing a total of 131 cedar and 124 Taurus fir trees. We evaluated six commonly used and well-known forestry taper functions developed by a variety of researchers (Biging (1984, Zakrzewski (1999, Muhairwe (1999, Fang et al. (2000, Kozak (2004, and Sharma and Zhang (2004. To address problems related to autocorrelation and multicollinearity in the hierarchical data associated with the construction of taper models, we used appropriate statistical procedures for the model fitting. We compared model performances based on the analysis of three goodness-of-fit statistics and found the compatible segmented model of Fang et al. (2000 to be superior in describing the stem profile and stem volume of both tree species in mixed stands. The equation used by Zakrzewski (1999 exhibited the poorest fitting results of the three taper equations. In general, we found segmented taper equations to provide more accurate predictions than variable-form models for both tree species. Results from the non-linear extra sum of squares method indicate that stem tapers differ among tree species in mixed stands. Therefore, a different taper function should be used for each tree species in mixed stands in the Bucak district. Using individual-specific taper equations yields more robust estimations and, therefore, will enhance the prediction accuracy of diameters at different heights and volumes in mixed stands.

  7. What killed Karl Patterson Schmidt? Combined venom gland transcriptomic, venomic and antivenomic analysis of the South African green tree snake (the boomslang), Dispholidus typus. (United States)

    Pla, Davinia; Sanz, Libia; Whiteley, Gareth; Wagstaff, Simon C; Harrison, Robert A; Casewell, Nicholas R; Calvete, Juan J


    Non-front-fanged colubroid snakes comprise about two-thirds of extant ophidian species. The medical significance of the majority of these snakes is unknown, but at least five species have caused life-threatening or fatal human envenomings. However, the venoms of only a small number of species have been explored. A combined venomic and venom gland transcriptomic approach was employed to characterise of venom of Dispholidus typus (boomslang), the snake that caused the tragic death of Professor Karl Patterson Schmidt. The ability of CroFab™ antivenom to immunocapture boomslang venom proteins was investigated using antivenomics. Transcriptomic-assisted proteomic analysis identified venom proteins belonging to seven protein families: three-finger toxin (3FTx); phospholipase A 2 (PLA 2 ); cysteine-rich secretory proteins (CRISP); snake venom (SV) serine proteinase (SP); C-type lectin-like (CTL); SV metalloproteinases (SVMPs); and disintegrin-like/cysteine-rich (DC) proteolytic fragments. CroFab™ antivenom efficiently immunodepleted some boomslang SVMPs. The present work is the first to address the overall proteomic profile of D. typus venom. This study allowed us to correlate the toxin composition with the toxic activities of the venom. The antivenomic analysis suggested that the antivenom available at the time of the unfortunate accident could have exhibited at least some immunoreactivity against the boomslang SVMPs responsible for the disseminated intravascular coagulation syndrome that caused K.P. Schmidt's fatal outcome. This study may stimulate further research on other non-front-fanged colubroid snake venoms capable of causing life-threatening envenomings to humans, which in turn should contribute to prevent fatal human accidents, such as that unfortunately suffered by K.P. Schmidt. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

Daptomycin is a lipopeptide antibiotic with concentration-dependent killing characteristic and dose-dependent post-antibiotic effect. To achieve optimized pharmacodynamic effect, some experts advocated using a high dose of daptomycin (≥9 mg/kg for severe infections. However, the safety of high-dose therapy in patients with renal impairment remains unknown. This study was aimed to evaluate the safety of daptomycin in patients with severe renal impairment. Methods: This was a retrospective study performed by reviewing electronic medical records. Patients with severe renal impairment who were treated with daptomycin in a tertiary teaching hospital between January 1, 2013, and June 30, 2016, were included for evaluation. The incidence rates of creatine kinase (CK elevation between high-dose (≥9 mg/kg and standard-dose (<9 mg/kg groups were compared. Results: Overall, 164 patients met the inclusion criteria, and 114 (69.5% of them were on renal replacement therapy. Vancomycin-resistant enterococci were the most common pathogens (61.3% of the patients with documented pathogens. The treatment success rate was 51.6% in the 91 patients with bacteremia. The average dose of daptomycin was 8.0±2.3 mg/kg, and 37 (22.6% patients received ≥9 mg/kg. CK levels were followed in 108 (65.9% patients. Significantly higher incidence of CK elevation was found in the high-dose group compared with that in the standard-dose group (10.8% vs 1.6%, P<0.05. Moreover

    Zhu, J


    Living in a period when the Buddhism was quite flourishing, Sun had a close contact with the monk Dao Xuan, the founder of Nanshan Sect Buddhism. Sun's Quian jin fang adopted all schools including Buddhism, evidenced by the following 3 aspects: 1) Direct Buddhist influence, mainly on medical morality; 2) Indian medicine coming together with Buddhism, including the theory of "four - element theory", the conception of all matters are medicines, pills of all disorders, recipes, and keep - fit art. Buddhism acts as a carrier here; 3) the achievements of treatment for beriberi by monks. However, Buddhist influence was far inferior to Taoism as far as Sun's work is concerned.

    Objective: To investigate the late effect of radiation on child-bearing women, through observing 'Fang', a 19-week-pregnant woman at age of 23, who was exposed to 60 Co radiation in Shanxi Xinzhou radiation accident in November, 1992 and diagnosed as moderate bone marrow type acute radiation sickness and recovered after 16 year of follow-up treatment. Methods: Clinical data including medical history, physical examination, laboratory data, imaging findings and consulting relevant departments were reviewed. Results: The followed-up woman 'Fang' often felt weak and caught cold after recovery. When she was 32 years old (9 years after radiation), her hair turned grey, but without hair loss. Her menstrual quantitiy was lessened since 31 years old (8 years after radiation). She was remarried and pregnant twice in the same year. At the first time she underwent artificial abortion and the second child suffered from intrauterine death after 6 months of pregnancy. The physical examination found bilateral degree I thyroid enlargement and sparse armpit hair. The laboratory test showed the increased levels of triiodothyronine, thyroxine and anti-thyroid peroxidase antibody (TMAb) and the decreased thyroid stimulating hormone (TSH). Unstable chromosome aberrations were totally lost and stable aberrations in chromosomes were detected by fluorescence in situ hybridization (FISH). The dose estimated with the residue chromosome aberration was 0.76 Gy. Other laboratory results were normal. Ultrasonic test showed diffuse lesion in bilateral thyroid and multiple cystic nodules in right lobe of thyroid, which was considered to be nodular goiter. The examination of bone mineral density (BMD) showed osteoporosis from the second to the fourth lumber vertebra. There were no diseases associated with radiation based on the consultation from related departments. Conclusions: Intrauterine death after 6 months of pregnancy might be associated with the previous exposure. There is no evidence of

    To investigate the comparative efficacy of cognitive behavioral therapy (CBT), Tai Chi Chih (TCC), and sleep seminar education control (SS) on the primary outcome of insomnia diagnosis, and secondary outcomes of sleep quality, fatigue, depressive symptoms, and inflammation in older adults with insomnia. Randomized controlled, comparative efficacy trial. Los Angeles community. 123 older adults with chronic and primary insomnia. Random assignment to CBT, TCC, or SS for 2-hour group sessions weekly over 4 months with follow-up at 7 and 16 months. Insomnia diagnosis, patient-reported outcomes, polysomnography (PSG), and high-sensitivity C-reactive protein (CRP) levels. CBT performed better than TCC and SS in remission of clinical insomnia as ascertained by a clinician (P 3.0 mg/L) at 16 months (odds ratio [OR], 0.26 [95% CI, 0.07-0.97] P insomnia was associated with lower levels of CRP (P insomnia remission. PSG measures did not change. Treatment of late-life insomnia is better achieved and sustained by cognitive behavioral therapies. Insomnia treatment and remission reduces a marker of inflammatory risk, which has implications for cardiovascular morbidity and diabetes observed with sleep disturbance in epidemiologic surveys. © 2014 Associated Professional Sleep Societies, LLC.

    Abstract: SAPS simulation with GITM/UCLA-RCM coupled model Author: Yang Lu, Yue Deng, Jiapeng Guo, Donghe Zhang, Chih-Ping Wang, Cheng Sheng Ion velocity in the Sub Aurora region observed by Satellites in storm time often shows a significant westward component. The high speed westward stream is distinguished with convection pattern. These kind of events are called Sub Aurora Polarization Stream (SAPS). In March 17th 2013 storm, DMSP F18 satellite observed several SAPS cases when crossing Sub Aurora region. In this study, Global Ionosphere Thermosphere Model (GITM) has been coupled to UCLA-RCM model to simulate the impact of SAPS during March 2013 event on the ionosphere/thermosphere. The particle precipitation and electric field from RCM has been used to drive GITM. The conductance calculated from GITM has feedback to RCM to make the coupling to be self-consistent. The comparison of GITM simulations with different SAPS specifications will be conducted. The neutral wind from simulation will be compared with GOCE satellite. The comparison between runs with SAPS and without SAPS will separate the effect of SAPS from others and illustrate the impact on the TIDS/TADS propagating to both poleward and equatorward directions.

  20. Tears of Venom: Hydrodynamics of Reptilian Envenomation (United States)

    Young, Bruce A.; Herzog, Florian; Friedel, Paul; Rammensee, Sebastian; Bausch, Andreas; van Hemmen, J. Leo


    In the majority of venomous snakes, and in many other reptiles, venom is conveyed from the animal’s gland to the prey’s tissue through an open groove on the surface of the teeth and not through a tubular fang. Here we focus on two key aspects of the grooved delivery system: the hydrodynamics of venom as it interacts with the groove geometry, and the efficiency of the tooth-groove-venom complex as the tooth penetrates the prey’s tissue. We show that the surface tension of the venom is the driving force underlying the envenomation dynamics. In so doing, we explain not only the efficacy of the open groove, but also the prevalence of this mechanism among reptiles.

  5. Buccal venom gland associates with increased of diversification rate in the fang blenny fish Meiacanthus (Blenniidae; Teleostei). (United States)

    Liu, Shang-Yin Vanson; Frédérich, Bruno; Lavoué, Sébastien; Chang, Jonathan; Erdmann, Mark V; Mahardika, Gusti Ngurah; Barber, Paul H


    At the macroevolutionary level, many mechanisms have been proposed to explain explosive species diversification. Among them morphological and/or physiological novelty is considered to have a great impact on the tempo and the mode of diversification. Meiacanthus is a genus of Blenniidae possessing a unique buccal venom gland at the base of an elongated canine tooth. This unusual trait has been hypothesized to aid escape from predation and thus potentially play an important role in their pattern of diversification. Here, we produce the first time-calibrated phylogeny of Blenniidae and we test the impact of two morphological novelties on their diversification, i.e. the presence of swim bladder and buccal venom gland, using various comparative methods. We found an increase in the tempo of lineage diversification at the root of the Meiacanthus clade, associated with the evolution of the buccal venom gland, but not the swim bladder. Neither morphological novelty was associated with the pattern of size disparification in blennies. Our results support the hypothesis that the buccal venom gland has contributed to the explosive diversification of Meiacanthus, but further analyses are needed to fully understand the factors sustaining this burst of speciation.

  6. Weighted multiscale Rényi permutation entropy of nonlinear time series (United States)

    Chen, Shijian; Shang, Pengjian; Wu, Yue


    In this paper, based on Rényi permutation entropy (RPE), which has been recently suggested as a relative measure of complexity in nonlinear systems, we propose multiscale Rényi permutation entropy (MRPE) and weighted multiscale Rényi permutation entropy (WMRPE) to quantify the complexity of nonlinear time series over multiple time scales. First, we apply MPRE and WMPRE to the synthetic data and make a comparison of modified methods and RPE. Meanwhile, the influence of the change of parameters is discussed. Besides, we interpret the necessity of considering not only multiscale but also weight by taking the amplitude into account. Then MRPE and WMRPE methods are employed to the closing prices of financial stock markets from different areas. By observing the curves of WMRPE and analyzing the common statistics, stock markets are divided into 4 groups: (1) DJI, S&P500, and HSI, (2) NASDAQ and FTSE100, (3) DAX40 and CAC40, and (4) ShangZheng and ShenCheng. Results show that the standard deviations of weighted methods are smaller, showing WMRPE is able to ensure the results more robust. Besides, WMPRE can provide abundant dynamical properties of complex systems, and demonstrate the intrinsic mechanism.

    Huang, Lu-qi; Qiu, Le


    The origin of northern Artemisia argyi recorded in Compendium of Materia Medica(Bencao gangmu) is Fudao(Chinese characters) in Tangyin county, While there is only Fudao(Chinese characters) instead of Fudao(Chinese characters). Whether indeed Fudao(Chinese characters) is Fudao(Chinese characters)? By reviewing the genuine evolution of A. argyi, doing textual research on Fudao(Chinese characters) and combing with field survey data of national census of Chinese Materia Medica resources, this paper concluded that the word Fudao(Chinese characters) firstly emerged in Figure Canon of Chinese Materia Medica(Bencao tujing) of Susong in Song dynasty and was applied in later generations, but the implication was not clear, then emerged both Tangyin and Fudao(Chinese characters) in Compendium of Materia Medica(Bencao gangmu). The place Fudao(Chinese characters) is one of the graves of Bianque, that existed from Shang and Zhou dynasty and never changed until now, the A. argyi of Tangyin was famous from the grave of Bianque in Fudao(Chinese characters), which could infer that Lishizhen considered Fudao (Chinese characters) was Fudao(Chinese characters) indeed, and the origin of northern A. argyi was Fudao(Chinese characters) in Tangyin county.

    Full Text Available Shao-Hsi Chung,1 Kuo-Chih Cheng2 1Department of Business Administration, Meiho University, Pingtung, Taiwan; 2Department of Accounting, National Changhua University of Education, Changhua City, Taiwan Background: The sunk cost effect is the scenario when individuals are willing to continue to invest capital in a failing project. The purpose of this study was to explain such irrational behavior by exploring how sunk costs affect individuals’ willingness to continue investing in an unfavorable project and to understand the role of cognitive dissonance on the sunk cost effect. Methods: This study used an experimental questionnaire survey on managers of firms listed on the Taiwan Stock Exchange and Over-The-Counter. Results: The empirical results show that cognitive dissonance does not mediate the relationship between sunk costs and willingness to continue an unfavorable investment project. However, cognitive dissonance has a moderating effect, and only when the level of cognitive dissonance is high does the sunk cost have significantly positive impacts on willingness to continue on with an unfavorable investment. Conclusion: This study offers psychological mechanisms to explain the sunk cost effect based on the theory of cognitive dissonance, and it also provides some recommendations for corporate management. Keywords: sunk costs, sunk cost effect, cognitive dissonance, behavior, unfavorable investment

    Before the upgraded vertex detector for the Belle II experiment at the SuperKEKB collider in Japan will be installed, a dedicated detector system for machine commissioning (BEAST II) will be employed. One of its main objectives is to measure and characterize the different background types in order to ensure a safe environment before the installation of the actual silicon detector systems close to the interaction point. FANGS, a detector system at BEAST II, based on ATLAS-IBL front-end electronics and planar silicon sensors is currently being developed for this purpose. The unique feature of this detector system is the high energy resolution achieved by using an external FPGA clock to sample the time-over-threshold signal, while keeping the excellent timing properties. The complete detector system is presented in this talk.

  18. Observations on the Chinese idea of fate

    Directory of Open Access Journals (Sweden)

    Gunnar Sjöholm


    Full Text Available Throughout the history of Chinese religion, ideas of fate are present. The earliest forms of Chinese writing occur on thousands of tortoise shells found 65 years ago in the province of Honan. At that time inscriptions on bronze vessels from the first millennium B.C. were already known. But the new material was more difficult to interpret. The amount of material has grown since then: there are now about 100 000 inscribed shells and bones, some hundreds of whole tortoise shields with inscriptions as well as other archaeological material. One third of the signs has been deciphered. The inscriptions are mostly quite brief and contain oracle formulas. The people of the Shang-Yin dynasty (1500-1028 B.C. knew the useful and the beautiful. What did the oracle stand for? Did it represent something necessary? An oracular technique had been developed, "which consisted in touching shells or bones on one side with a little red-hot rod and interpreting according to certain patterns the cracks that arose on the other side as the answers of the ancestral spirits to the questions of the kings. After the consultation of the oracle the questions and often the answers were inscribed beside the cracks. Often also pure memoranda concerning weather, war expeditions etc. were inscribed.

  19. Pattern Classification in Kampo Medicine

    Directory of Open Access Journals (Sweden)

    S. Yakubo


    Full Text Available Pattern classification is very unique in traditional medicine. Kampo medical patterns have transformed over time during Japan’s history. In the 17th to 18th centuries, Japanese doctors advocated elimination of the Ming medical theory and followed the basic concepts put forth by Shang Han Lun and Jin Gui Yao Lue in the later Han dynasty (25–220 AD. The physician Todo Yoshimasu (1702–1773 emphasized that an appropriate treatment could be administered if a set of patterns could be identified. This principle is still referred to as “matching of pattern and formula” and is the basic concept underlying Kampo medicine today. In 1868, the Meiji restoration occurred, and the new government changed its policies to follow that of the European countries, adopting only Western medicine. Physicians trained in Western medicine played an important role in the revival of Kampo medicine, modernizing Kampo patterns to avoid confusion with Western biomedical terminology. In order to understand the Japanese version of traditional disorders and patterns, background information on the history of Kampo and its role in the current health care system in Japan is important. In this paper we overviewed the formation of Kampo patterns.

    Ling, He; Qingrong, Zhao; Min, Gao


    This paper presents the result of scientific examinations carried out on the soil-buried archaeological bronzes Ding from Yin Ruins of China. Eight of typical fragments from different bronze Ding were selected as researched samples according to their deterioration characteristics. Optical microscopy (OM), scanning electron microscopy coupled with energy (SEM-EDX), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were used to understand the corrosive morphological characteristics, to clear the nature of patina and to analyze the elementary composition of bronze Ding. The results indicated that it is not possible to distinguish the original lustrous metallic surface in most samples because of the corrosive crust. The substrate of bronze Ding contains74-86% Cu, 1.1-4.6% Pb, and 10-18% Sn, which is in agreement with the historical investigation in the ritual vessels of Shang time. Copper-containing compounds were the main constituents of natural patina: Cu 2 (OH) 3 Cl existed as corrosion product in all the powdery or crack surface; Cu 2 (OH) 2 CO 3 was the main corrosive product in a compact and hard corrosive surface. This study provides useful information for the restoration and protection of bronze Ding in Yin Ruins

    Full Text Available The present study was an attempt to compare the effect of teaching Collaborative Strategic Reading (CSR and Content-Based Instruction (CBI on the reading comprehension of English as a Foreign Language (EFL learners. To fullfill this objective, a group of 90 intermediate female EFL learners, within the age range of 17 to 19, took a piloted sample of the PET as a pre-treatment proficiency test. Sixty of them were selected as homogeneous learners and were randomly divided into two experimental groups of CSR and CBI. The CSR group receieved CSR strategy training based on Klingner, Vaughan, and Schumm's model (2001, while the CBI group receieved CBI-based strategy training, using Tsai and Shang's (2010 model. At the end of the training, another piloted PET reading test was administered  as the posttest. The pre-treatment reading scores were analyzed using the Mann-Whitney U test whose results confirmed the pre-treatment homogeneity of the participants. The post-treatment scores were also analyzed using the Mann-Whitney U test whose results indicated no significant difference in the reading posttest levels of CBI and CSR groups, U = 423.5, z = -.401, p = .688, r = -.0517. The article concludes with a discussion on the results and presenting some implications.

    The argument surrounding the safety and effectiveness of interventions for the population of individuals at a clinical high risk of developing psychosis has been ongoing for the past 30 years. However, few studies have assessed the needs of this special young population, who are struggling with the recent onset of psychotic symptoms. The sample consisted of 171 family members of 108 clinical high-risk individuals included from the ShangHai at Risk for Psychosis research programme. A 'WeChat' group was established to provide mutual support. There were 22,007 valid messages sent within the group between 1 April 2015 and 27 June 2016. Chat records were subsequently analysed to determine the needs of families during intervention at the early stages of psychosis. Families of clinical high-risk individuals were highly involved in the entire medical process, and the major concerns of the families of clinical high-risk individuals focused on both functional recovery and medication. The themes of 'take medication', 'go to school' and 'study in school' were often discussed within the group. A family-focused intervention targeting functional recovery and real-time professional explanations of medication would meet the major needs of families of Chinese clinical high-risk individuals.

University Street, Ann Arbor, MI 48109 (United States); Megeath, Tom, E-mail: [Ritter Astrophsical Research Center, Department of Physics and Astronomy, University of Toledo, Toledo, OH 43606 (United States)


    NGC 1980 is a young cluster that is located about 0.°5 south of the Orion Nebula Cluster (ONC). Recent studies by Bouy et al. and Pillitteri et al. have suggested that NGC 1980 contains an older population of stars compared to a much younger ONC, and that it belongs to a foreground population that may be located in front of the Orion A molecular gas by as much as 40 pc. In this work, we present low-resolution spectra toward 148 young stars found toward the NGC 1980 region. We determine the spectral types of these stars, examine accretion signatures and measure the extinction toward them. We determine that based on these observations, the age of the population of NGC 1980 is indistinguishable from L1641, estimated to be ∼3 Myr, comparable with the study by Fang et al.

    Full Text Available In work the presented numerical models of tool steel hardening processes take into account mechanical phenomena generated by thermalphenomena and phase transformations. In the model of mechanical phenomena, apart from thermal, plastic and structural strain, alsotransformations plasticity was taken into account. The stress and strain fields are obtained using the solution of the Finite Elements Method of the equilibrium equation in rate form. The thermophysical constants occurring in constitutive relation depend on temperature and phase composite. For determination of plastic strain the Huber-Misses condition with isotropic strengthening was applied whereas fordetermination of transformation plasticity a modified Leblond model was used. In order to evaluate the quality and usefulness of thepresented models a numerical analysis of stresses and strains associated hardening process of a fang lathe of cone shaped made of tool steel was carried out.

    In this paper, the influence of coal bottom ash and tincal additions on the physical properties and microstructures of the standard wall tile body composition was investigated. Water absorption, fang strength, dry and fired shrinkage tests of the incorporated ceramic bodies and reference body were done. Microstructures of sintered tiles were analyzed using a scanning electron microscope (SEM). The results show that tincal additions to the ceramic body improved the physical properties of the tiles. As a result, tincal can be used as a flux material in the ceramic bodies due to its favorable effects on the water absorption and fired strength. The results revealed that bottom ash can be used in the ceramic tile body composition. When bottom ash was used in the ceramic industry, environmental hazards of bottom ash are inhibited. Furthermore, bottom ash is transformed to an economic product.

    Entering and developing presence in emerging economies often require foreign firms to set up International Joint Ventures (IJVs) with local partners, especially when the prime motive of the operation is to capture opportunities in the local markets (Mohr & Puck, 2005). IJVs have therefore become...... an important way for firms to enter these markets and a significant force in shaping a firm’s global strategy in expanding international activities abroad. However, research has shown that IJVs in emerging economies are unstable, and firms have experienced that performance of their IJVs in these emerging...... economies often does not meet their expectations (Fang & Zou, 2010). Extant research has shown that, in general, management of IJVs appears to be a difficult issue. 60-70% of all partnerships are not successful (Lambe, Spekman, & Hunt, 2002).

    Electronic transport properties of a kind of phenylacetylene compound— (4-mercaptophenyl)-phenylacetylene are calculated by the first-principles method in the framework of density functional theory and the nonequilibrium Green's function formalism. The molecular junction shows an obvious rectifying behaviour at a bias voltage larger than 1.0 V. The rectification effect is attributed to the asymmetry of the interface contacts. Moreover, at a bias voltage larger than 2.0 V, which is not referred to in a relevant experiment [Fang L, Park J Y, Ma H, Jen A K Y and Salmeron M 2007 Langmuir 23 11522], we find a negative differential resistance phenomenon. The negative differential resistance effect may originate from the change of the delocalization degree of the molecular orbitals induced by the bias.

  13. Modelacio de sedimentadors en plantes de tractament d'aigues residuals. Aplicacio al proces de fermentacio - elutracio de fangs primaris (United States)

    Ribes Bertomeu, Josep

    Wastewater treatments require the execution of many conversion processes simultaneously and/or consecutively, making them a tricky object of study. Furthermore, complexity of treatment processes is increasing not only for the more stringent effluent standards required, but also for the new trends towards sustainable development, which in this process are mainly focused on energy saving and nutrient recovery from wastewaters in order to improve their life cycle. For this reason it becomes necessary to use simulation tools which are able to represent all these processes by means of a suitable mathematical model. They can help in determining and predicting the behaviour of the different treatment schemes. These simulators have become essential for the design, control and optimization of wastewater treatment plants (WWTP). Settling processes have a significant role in the accomplishment of effluent standards and the correct operation of the plant. However, many models that are currently employed for WWTP design and simulation do not take into account settling processes or they are handled in a very simple way, by neglecting the biochemical processes that can occur during sedimentation. People of CALAGUA research group have focussed their efforts towards a new philosophy of simulating treatment plants, which is based on the use of a unique model to represent all physical, chemical and biological processes taking place in WWTPs. In this research topic, they have worked on the development of a general quality model that considers biological conversion processes carried out by different microorganism groups, acid base chemical interactions affecting the pH value in the system, and gas-liquid transfer processes. However, a generalized use of such a quality model requires its combination with a flux model, principally for those processes where completely mixture can not be assumed, as for instance, settlers and thickeners in WWTPs. The main objective of this work has been the development and validation of a general settling model that allows simulating the main settling operations taking place in a WWTP, considering both primary and secondary settlers and thickeners. It consists in a one-dimensional model based on the flux theory of Kynch and the double-exponential settling function of Takacs that takes into account flocculation, hindered settling and compression processes. The model has been applied to simulation of settlers and thickeners by means of splitting the system into several horizontal layers, all of them considered as completely mixed reactors which are interconnected by mass flux obtained from the settling model. In order to simulate the conversion processes taking place during sedimentation, the general quality model BNRM1 has been added, and it has been proposed an iterative procedure for solving the equations for each layer in which the settler has been divided. The settling flux model validation, along with the quality model, has been carried out by applying them to a simulation of primary sludge fermentation - elutriation process. This process has been studied on a pilot plant located in the Carraixet WWTP in Alboraia (Valencia). In order to simulate the observed decrease in solids separation efficiency in the studied fermentation - elutriation process, the quality model has been modified with the addition of a new process called "disintegration of complex particulate material". This process influences the settleability of the sludge because it is considered that the disintegrated solids become non-settleable solids. This modification implies the addition of two new kinetic parameters (the specific disintegration velocity for volatile particulate material and the specific disintegration velocity for non volatile particulate material). However, the settling parameter that represents the non-settleable fraction of total suspended solids is eliminated from the model and it has been transformed into an experimental variable which is quite easy to analyze. The result of this modification is a more general model, which is applicable to fermentation - elutriation process working at any operating condition. Finally, the behaviour and capabilities of the developed model have been tested by simulating a complete WWTP on the DESASS simulation software, developed by the research group. This example includes the most important processes that can be used in a WWTP: biological nutrient removal, primary sludge fermentation and sludge digestion. The model allows considering both settling processes and biochemical processes as a whole (denitrification in secondary settlers, primary sludge fermentation and VFA elutriation, phosphorus release in thickeners because of the PAO decay, etc.). The developed model implies an important advance in study of new wastewater treatment processes because it allows dealing with global process optimization problems, by means of full plants simulation. It is very useful for studying the effects of a modification in operation conditions of one element over the operation of the rest of the elements of the WWTP. (Abstract shortened by UMI.).

WGA-conjugated and CL-incorporated liposomes (WGA-CL-liposomes were used to transport nerve growth factor (NGF and curcumin (CUR across a monolayer of human brain-microvascular endothelial cells regulated by human astrocytes and to protect SK-N-MC cells against apoptosis induced by ß-amyloid1–42 (Aß1–42 fibrils. An increase in the CL mole percentage in lipids increased the liposomal diameter, absolute zeta potential value, entrapment efficiency of NGF and CUR, release of NGF, biocompatibility, and viability of SK-N-MC cells with Aß1–42, but decreased the atomic ratio of nitrogen to phosphorus and release of CUR. In addition, an increase in the WGA concentration for grafting enhanced the liposomal diameter, atomic ratio of nitrogen to phosphorus, and permeability of NGF and CUR across the blood–brain barrier, but reduced the absolute zeta potential value and biocompatibility. WGA-CL-liposomes carrying NGF and CUR could be promising colloidal delivery carriers for future clinical application in targeting the blood–brain barrier and inhibiting neurotoxicity.

  16. Superfluidity and BCS-BEC crossover of ultracold atomic Fermi gases in mixed dimensions (United States)

    Zhang, Leifeng; Chen, Qijin

    Atomic Fermi gases have been under active investigation in the past decade. Here we study the superfluid and pairing phenomena of a two-component ultracold atomic Fermi gas in the presence of mixed dimensionality, in which one component is confined on a 1D optical lattice whereas the other is free in the 3D continuum. We assume a short-range pairing interaction and determine the superfluid transition temperature Tc and the phase diagram for the entire BCS-BEC crossover, using a pairing fluctuation theory which includes self-consistently the contributions of finite momentum pairs. We find that, as the lattice depth increases and the lattice spacing decreases, the behavior of Tc becomes very similar to that of a population imbalance Fermi gas in a simple 3D continuum. There is no superfluidity even at T = 0 below certain threshold of pairing strength in the BCS regime. Nonmonotonic Tc behavior and intermediate temperature superfluidity emerge, and for deep enough lattice, the Tc curve will split into two parts. Implications for experiment will be discussed.

Because of their amphiphilic character and hollow architecture, RNTs can be used to encapsulate and deliver hydrophobic drugs otherwise difficult to deliver in biological systems. Another advantage of using RNTs for drug delivery is their biocompatibility, low cytotoxicity, and their ability to engender a favorable, biologically-inspired environment for cell adhesion and growth. In this study, a method to incorporate dexamethasone (DEX, an inflammatory and a bone growth promoting steroid into RNTs was developed. The drug-loaded RNTs were characterized using diffusion ordered nuclear magnetic resonance spectroscopy (DOSY NMR and UV-Vis spectroscopy. Results showed for the first time that DEX can be easily and quickly encapsulated into RNTs and released to promote osteoblast (bone-forming cell functions over long periods of time. As a result, RNTs are presented as a novel material for the targeted delivery of hydrophobic drugs otherwise difficult to deliver.Keywords: nanotubes, drug delivery, self-assembly, physiological conditions

Morris water maze test was conducted before and after the treatment to observe cognitive function. Fluorine 18-deoxy glucose [F-18]FDG micro-PET brain imaging scans was performed after treatment. Data were analyzed with two-sample t-test (Pfunctions, TMGTP induced strong brain activity in the following sites: right dorsolateral nucleus and ventrolateral nucleus of thalamus, amygdala, left met thalamus, cerebellum leaflets, original crack, front cone crack, loop-shaped leaflets; but deactivation of right medial frontal gyrus, bilateral corpus callosum, hippocampus, and left dentate gyrus. TMGTP could alleviate cognitive dysfunction in SHRs with GYSK, which was possibly by inducing alteration of glucose metabolism in different brain regions with corresponding functions.

    Zhou, Zhanru; Fang, Xiande; Li, Dingkun


    The calculation of two-phase flow boiling heat transfer of R22 in channels is required in a variety of applications, such as chemical process cooling systems, refrigeration, and air conditioning. A number of correlations for flow boiling heat transfer in channels have been proposed. This work evaluates the existing correlations for flow boiling heat transfer coefficient with 1669 experimental data points of flow boiling heat transfer of R22 collected from 18 published papers. The top two correlations for R22 are those of Liu and Winterton (1991) and Fang (2013), with the mean absolute deviation of 32.7% and 32.8%, respectively. More studies should be carried out to develop better ones. Effects of channel dimension and vapor quality on heat transfer are analyzed, and the results provide valuable information for further research in the correlation of two-phase flow boiling heat transfer of R22 in channels.

  4. Optimization of scanning strategy of digital Shack-Hartmann wavefront sensing. (United States)

    Guo, Wenjiang; Zhao, Liping; Li, Xiang; Chen, I-Ming


    In the traditional Shack-Hartmann wavefront sensing (SHWS) system, a lenslet array with a bigger configuration is desired to achieve a higher lateral resolution. However, practical implementation limits the configuration and this parameter is contradicted with the measurement range. We have proposed a digital scanning technique by making use of the high flexibility of a spatial light modulator to sample the reflected wavefront [X. Li, L. P. Zhao, Z. P. Fang, and C. S. Tan, "Improve lateral resolution in wavefront sensing with digital scanning technique," in Asia-Pacific Conference of Transducers and Micro-Nano Technology (2006)]. The lenslet array pattern is programmed to laterally scan the whole aperture. In this paper, the methodology to optimize the scanning step for the purpose of form measurement is proposed. The correctness and effectiveness are demonstrated in numerical simulation and experimental investigation. © 2012 Optical Society of America

EATL most commonly presents in the sixth and seventh decades of life. We report a unique case of type I EATL in the colon with liver metastasis, which was presented with nonspecific radiological findings and at a very young age (29 years old compared with previously published data. We suggest that EATL should be regarded as part of differential diagnosis in any patient presenting with abdominal pain, diarrhea, weight loss, and malabsorption because delay in treatment can result in an irreversible clinical outcome.

    Molecular-Beam Epitaxy growth of multiple In 0.4 Ga 0.6 As layers on GaAs (311)A and GaAs (331)A has been investigated by Atomic Force Microscopy and Photoluminescence. On GaAs (311)A, uniformly distributed In 0.4 Ga 0.6 As quantum wires (QWRs) with wider lateral separation were achieved, presenting a significant improvement in comparison with the result on single layer [H. Wen, Z.M. Wang, G.J. Salamo, Appl. Phys. Lett. 84 (2004) 1756]. On GaAs (331)A, In 0.4 Ga 0.6 As QWRs were revealed to be much straighter than in the previous report on multilayer growth [Z. Gong, Z. Niu, Z. Fang, Nanotechnology 17 (2006) 1140]. These observations are discussed in terms of the strain-field interaction among multilayers, enhancement of surface mobility at high temperature, and surface stability of GaAs (311)A and (331)A surfaces.

    Loutas, Nikolaos; Giantsiou, Lemonia; Peristeras, Vassilios; Tarabanis, Konstantinos

    During the past years, governments have made significant efforts to improve both their internal processes and the services that they provide to citizens and businesses. These led to several successful e-Government applications (e.g., see One of the most popular tools that was used by governments in order to modernize their services and make them accessible is e-Government portals, e.g., (Drigas et al. 2005), (Fang 2002). The main goals of such portals are: To make available complete, easy to understand, and structured information about public services and public administration's modus operandi, which will assist citizens during the service provision process. To facilitate the electronic execution of public services. Nevertheless, most of such efforts did not succeed. Gartner argues that most e-Government strategies have not achieved their objectives and have failed to trigger sustainable government transformation to greater efficiency and citizen-centricity (DiMaio 2007).

Chemisorption of polymers onto GNS was verified by a red shift in the ultraviolet–visible spectrum as well as by a change in the nanoparticle surface charge. The physicochemical properties of pristine and functionalized nanoparticles were analyzed by ultraviolet–visible spectroscopy, zeta potential analyzer, and transmission electron microscopy. Transmission electron microscopy revealed that the interparticle distance between nanoparticles increased after GNS functionalization. Comparing the skin permeation profile of pristine and functionalized GNS, the follicular deposition of GNS increased twofold after PEG–OAm functionalization. Moreover, PEG- and PEG–OAm-functionalized nanoparticles were able to overcome the skin barrier and deposit in the deeper subcutaneous adipose tissue. These findings demonstrate the potential of PEG- and PEG–OAm-functionalized GNS in serving a multitude of applications in transdermal pharmaceuticals.

Cell 2010, 141, 472-482 [1] provides new insights into the order of entry events, as well as confirming and refining several aspects of the entry mechanism, for aquareovirus and the related orthoreovirus. In particular, the structure provides evidence of a defined order for the progressive proteolytic cleavages of myristoylated penetration protein VP5 that prime the virion for membrane penetration. These observations reinforce the concept that, much like enveloped viruses, nonenveloped virions often undergo priming events that lead to a meta-stable state, preparing the virus for membrane penetration under the appropriate circumstances. In addition, this and other recent studies highlight the increasing power of electron cryomicroscopy to analyze large, geometrically regular structures, such as icosahedral viruses, at atomic resolution.

  13. State-to-state reactive scattering in six dimensions using reactant-product decoupling: OH + H2 → H2O + H (J = 0). (United States)

    Cvitaš, Marko T; Althorpe, Stuart C


    We extend to full dimensionality a recently developed wave packet method [M. T. Cvitaš and S. C. Althorpe, J. Phys. Chem. A 113, 4557 (2009)] for computing the state-to-state quantum dynamics of AB + CD → ABC + D reactions and also increase the computational efficiency of the method. This is done by introducing a new set of product coordinates, by applying the Crank-Nicholson approximation to the angular kinetic energy part of the split-operator propagator and by using a symmetry-adapted basis-to-grid transformation to evaluate integrals over the potential energy surface. The newly extended method is tested on the benchmark OH + H(2) → H(2)O + H reaction, where it allows us to obtain accurately converged state-to-state reaction probabilities (on the Wu-Schatz-Fang-Lendvay-Harding potential energy surface) with modest computational effort. These methodological advances will make possible efficient calculations of state-to-state differential cross sections on this system in the near future.

  14. Impacted science: impact is not importance. (United States)

    Casadevall, Arturo; Fang, Ferric C


    The journal impact factor (IF) exerts a tremendous influence on the conduct of scientists. The obsession with IF has been compared to a medical condition, sometimes referred to as "IF mania" or "impactitis." Here, we analyze the difference between impact and importance, using examples from the history of science to show that these are not equivalent. If impact does not necessarily equal importance, but scientists are focused on high-impact work, there is a danger that misuse of the IF may adversely affect scientific progress. We suggest five measures to fight this malady: (i) diversify journal club selections, (ii) do not judge science on the publication venue, (iii) reduce the reliance on journal citation metrics for employment and advancement, (iv) discuss the misuse of the IF in ethics courses, and (v) cite the most appropriate sources. If IF mania is indeed a medical condition, the most appropriate course of action may be disimpaction. Copyright © 2015 Casadevall and Fang.

    Palaeoflood slackwater deposits (SWDs) along the river banks have important implications for the reconstruction of the past hydro-climatic events. Two palaeoflood SWD beds were identified in the Holocene loess-soil sequences on the cliff river banks along the Gold Gorge of the upper Hanjiang River by field investigation and laboratory analysis. They have recorded two palaeoflood events which were dated by optically stimulated luminescence to 3.2-2.8 ka and 2.1-1.8 ka, respectively. The reliability of the ages obtained for the two events are further confirmed by the presence of archaeological remains and good regional pedostratigraphic correlation. The peak discharges of two palaeoflood events at the studied sites were estimated to be 16,560-17,930 m3/s. A correlation with the palaeoflood events identified in the other reaches shows that great floods occurred frequently during the episodes of 3200-2800 and 2000-1700 a BP along the upper Hanjiang River valley during the last 4000 years. These phases of palaeoflood events in central China are well correlated with the climatic variability identified by δ18O record in the stalagmites from the middle Yangtze River Basin and show apparent global linkages. Palaeoflood studies in a watershed scale also imply that strengthened human activities during the Shang dynasty (BCE 1600-1100) and Han dynasty (BCE206-CE265) may have caused accelerated soil erosion along the upper Hanjiang River valley.

Ginsenoside Rg1 (Rg1 has a wide variety of therapeutic values for central nervous system (CNS diseases for the neuron protective effects. However, the blood–brain barrier (BBB restricts Rg1 in reaching the CNS. In this study, we investigated the therapeutic effects of Rg1 nanoparticle (PHRO, fabricated with γ-PGA, L-PAE (H, Rg1, and OX26 antibody, targeting transferrin receptor, on the diabetes rats complicated with diabetic cerebral infarction in vitro and in vivo. Dynamic light scattering analysis shows the average particle size of PHRO was 79±18 nm and the polydispersity index =0.18. The transmission electron microscope images showed that all NPs were spherical in shape with diameters of 89±23 nm. PHRO released Rg1 with sustained release manner and could promote the migration of cerebrovascular endothelial cells and tube formation and even penetrated the BBB in vitro. PHRO could penetrate the BBB with high concentration in brain tissue to reduce the cerebral infarction volume and promote neuronal recovery in vivo. PHRO was promising to be a clinical treatment of diabetes mellitus with cerebral infarction. Keywords: poly-γ-glutamic acid, ginsenoside Rg1, OX26, blood–brain barrier

    Full Text Available Background: Neonatal jaundice is a relatively prevalent disease and affects approximately 2.4–15% newborns. Probiotics supplementation therapy could assist to improve the recovery of neonatal jaundice, through enhancing immunity mainly by regulating bacterial colonies. However, there is limited evidence regarding the effect of probiotics on bilirubin level in neonates. Therefore, this study aims at systematically evaluating the efficacy and safety of probiotics supplement therapy for pathological neonatal jaundice.Methods: Databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI, Wan Fang Database (Wan Fang, Chinese Biomedical Literature Database (CBM, VIP Database for Chinese Technical Periodicals (VIP were searched and the deadline is December 2016. Randomized controlled trials (RCTs of probiotics supplementation for pathological neonatal jaundice in publications were extracted by two reviewers. The cochrane tool was applied to assessing the risk of bias of the trials. The extracted information of RCTs should include efficacy rate, serum total bilirubin level, time of jaundice fading, duration of phototherapy, duration of hospitalization, adverse reactions. The main outcomes of the trials were analyzed by Review Manager 5.3 software. The relative risks (RR or mean difference (MD with a 95% confidence interval (CI was used to measure the effect.Results: 13 RCTs involving 1067 neonatal with jaundice were included in the meta-analysis. Probiotics supplementation treatment showed efficacy [RR: 1.19, 95% CI (1.12, 1.26, P < 0.00001] in neonatal jaundice. It not only decreased the total serum bilirubin level after 3day [MD: −18.05, 95% CI (−25.51, −10.58, P < 0.00001], 5day [MD: -23.49, 95% CI (−32.80, −14.18, P < 0.00001], 7day [MD: −33.01, 95% CI (−37.31, −28.70, P < 0.00001] treatment, but also decreased time of jaundice fading [MD: −1.91, 95% CI (−2.06, −1.75, P < 0.00001], as

The therapeutic efficacy of SM- and ApoE-grafted LIP carrying NGF (NGF-SM-ApoE-LIP was assessed by an in vitro Alzheimer’s disease (AD model of degenerated SK-N-MC cells and an in vivo AD model of Aβ-insulted Wistar rats. The experimental evidences revealed that the modified SM and ApoE on the surface of LIP increased the permeation of NGF across the BBB without serious damage to structural integrity of tight junction. When compared with free NGF, NGF-SM-ApoE-LIP upregulated the expression of phosphorylated neurotrophic tyrosine kinase receptor type 1 on cholinergic neurons and significantly improved their survival. In addition, NGF-SM-ApoE-LIP could reduce the secretion of acetylcholinesterase and malondialdehyde and rescue hippocampal neurons from apoptosis in rat brains. The synergistic effect of SM and ApoE is promising in the induction of NGF to inhibit the neurotoxicity of Aβ and NGF-SM-ApoE-LIP can be a potent antiapoptotic pharmacotherapy for clinical care of patients with AD.

    Australia is the stronghold of the front-fanged venomous snake family Elapidae. The Australasian elapid snake radiation, which includes approximately 100 terrestrial species in Australia, as well as Melanesian species and all the world’s true sea snakes, may be less than 12 million years old. The incredible phenotypic and ecological diversity of the clade is matched by considerable diversity in venom composition. The clade’s evolutionary youth and dynamic evolution should make it of particular interest to toxinologists, however, the majority of species, which are small, typically inoffensive, and seldom encountered by non-herpetologists, have been almost completely neglected by researchers. The present study investigates the venom composition of 28 species proteomically, revealing several interesting trends in venom composition, and reports, for the first time in elapid snakes, the existence of an ontogenetic shift in the venom composition and activity of brown snakes (Pseudonaja sp.). Trends in venom composition are compared to the snakes’ feeding ecology and the paper concludes with an extended discussion of the selection pressures shaping the evolution of snake venom.

    Chen, Lianghua; Chen, Junqi; Peng, Qiyuan; Chen, Jingjie; Zou, Yucong; Liu, Gang


    This study aims to evaluate the effect of sling exercise training (SET) on balance in patients with stroke. PubMed, Cochrane Library, Ovid LWW, CBM, CNKI, WanFang, and VIP databases were searched for randomized controlled trials of the effect of SET on balance in patients with stroke. The study design and participants were subjected to metrological analysis. Berg balance Scale (BBS), Barthel index score (BI), and Fugl-Meyer Assessment (FMA) were used as independent parameters for evaluating balance function, activities of daily living(ADL) and motor function after stroke respectively, and were subjected to meta-analysis by RevMan5.3 software. Nine studies with 460 participants were analyzed. Results of meta-analysis showed that the SET treatment combined with conventional rehabilitation was superior to conventional rehabilitation treatments, with increased degrees of BBS (WMD = 3.81, 95% CI [0.15, 7.48], P = 0.04), BI (WMD = 12.98, 95% CI [8.39, 17.56], P risk of bias. Therefore, more multi-center and large-sampled randomized controlled trials are needed to confirm its clinical applications.

    Charge transfer in collisions of Si{sup 4+} ions with He atoms below 100 keV/u is studied by using a molecular orbital representation within both the semiclassical and quantal representations. Single transfer reaction Si{sup 4+} + He {yields} Si{sup 3+} + He{sup +} has been studied by a number of theoretical investigations. In addition to the reaction (1), the first semiclassical MOCC calculations are performed for the double transfer channel Si{sup 4+} + He {yields} Si{sup 2+} + He{sup 2+}. Nine molecular states that connect both with single and double electron transfer processes are considered in the present model. Electronic states and corresponding couplings are determined by the multireference single- and double- excitation configuration interaction method. The present cross sections tie well with the earlier calculations of Stancil et al., (1997) at lower energies, but show a rather different magnitude from those of Bacchus-Montabonel and Ceyzeriat, (1998). The present rate constant is found to be significantly different from the experimental finding of Fang and Kwong, (1996) at 4,600 K, and hence does not support the experiment. (orig.)

    This meta-analysis examined the mean sleep duration and patterns in Chinese older adult population. A literature search was systematically conducted covering major English (PubMed, Embase and PsycINFO) and Chinese (Chinese National Knowledge Infrastructure (CNKI), WanFang and SinoMed) databases. Data in studies with the mean and standard deviation of sleep duration and/or the proportion of short and long sleep durations in Chinese older adults were extracted and pooled using random-effects models. Subgroup analyses were conducted according to gender, region, area, survey time and sample size. A total of 36 studies with 150,616 subjects were included for analyses. The pooled mean sleep duration of 21 studies with available data was 6.82 hours/day (95% CI: 6.59-7.05 hours/day). The estimated proportions of sleep duration 8 hours/day) and 17.6% (95% CI: 12.4%-22.9%) (>9 hours/day). Given the adverse effects of unhealthy sleep patterns, health professionals should pay more attention to sleep patterns in this population in China.

  9. Field Science--the Nature and Utility of Scientific Fields. (United States)

    Casadevall, Arturo; Fang, Ferric C


    Fields are the fundamental sociological units of science. Despite their importance, relatively little has been written about their emergence, composition, structure, and function in the scientific enterprise. This essay considers the nature of fields and their important role in maintaining information and providing normative standards for scientific work. We suggest that fields arise naturally as a consequence of increasing information and scientific specialization. New fields tend to emerge as research communities grow, which may reflect biologically determined optima for the size of human groups. The benefits of fields include the organization of scientists with similar interests into communities that collectively define the next important problems to pursue. In the discipline of microbiology, fields are often organized on the basis of phylogenetic differences between microorganisms being studied. Although fields are essential to the proper functioning of science, their emergence can restrict access by outsiders and sustain dogmas that hinder progress. We suggest mechanisms to improve the functioning of scientific fields and to promote interdisciplinary interaction between fields. Copyright © 2015 Casadevall and Fang.

  10. Biscrolling nanotube sheets and functional guests into yarns (United States)

    Baughman, Ray


    Multifunctional applications of textiles have been limited by the inability to spin important materials into yarns. Generically applicable methods are demonstrated for producing weavable yarns comprising up to 95 wt % of otherwise unspinnable particulate or nanofiber powders that remain highly functional. Scrolled 50 nm thick carbon nanotube sheets confine these powders in the galleries of irregular scroll sacks, whose observed complex structures are related to twist-dependent extension of Archimedean spirals, Fermat spirals, or spiral pairs into scrolls. The strength and electronic connectivity of a small weight fraction of scrolled carbon nanotube sheet enables yarn weaving, sewing, knotting, braiding, and charge collection. This technology is used to make yarns of superconductors, Li-ion battery materials, graphene ribbons, catalytic nanofibers for fuel cells, and Ti O2 for photocatalysis.

    Full Text Available The vulnerability assessment model, composed by 11 vulnerability factors, is established with the introduction of the concept of “vulnerability” into the assessment of tunnel support system. Analytic hierarchy process is utilized to divide these 11 factors into human attributes and natural attributes, and define the weight of these factors for the model. The “vulnerability” applied io the assessment of the tunnel support system model is reached. The vulnerability assessment model was used for evaluating and modifying the haulage tunnel #3207 of Bo-fang mine panel #2. The results decreased the vulnerability of the tunnel support system and demonstrated acceptable effects. Furthermore, the results show that the impact of human attributes on tunnel support systems is dramatic under the condition that natural attributes are permanent, and the “vulnerability” is exactly a notable factor to manifest the transformation during this process. The results also indicate that optimizing human attributes can attenuate vulnerability in tunnel support systems. As a result, enhancement of stability of tunnel support systems can be achieved.

While increasing evidence has linked nurse work environment to various patient outcomes, no systematic review has assessed evidence examining nurse work environment in relation to readmission. Methods: This review was guided by the Institute of Medicine's Standards for Systematic Reviews. Comprehensive searches were conducted in PubMed, CINAHL, and PsycINFO, and were complemented by hand searching. Two reviewers independently completed full-text review and quality assessment using a validated tool. Results: Ten studies met the inclusion criteria and were included for final review. Various methods were used to measure readmission and nurse work environment, and analyses were conducted at both the patient and hospital levels. Overall, associations between nurse work environment and readmission emerged, and better nurse work environments (particularly higher levels of nurse staffing were associated with fewer readmissions. Discussion: The interpretation of results from each study was limited by the differences in variable measures across studies and methodological flaws. The relationship between nurse work environment and readmission needs to be further confirmed by stronger evidence from studies using standardized measures and more rigorous research design.

    Full Text Available In a survey for rust diseases in Maragheh area rust symptoms were observed on poplars (Populus nigra in Maragheh city parks and orchards near the city. Uredinia and urediniospores typical of Melampsora were present on the underside of leaves. Paraphyses were clavate with walls evenly thick and Telia, formed on the leaves early in the autumn, were epiphyllous and subepidermal. DNA was extracted from urediniospores and the primers ITS1 and ITS4 were used to amplify the internal transcribed spacer region of the ribosomal DNA. Based on the key provided by Bagyanarayana and the species description by Pei and Shang, and the result of sequencing, the causal agent was identified as Melampsora allii-populina Kelb. Melampsora species are mainly determined based on their morphology, alternate hosts and telial host range. However, in most cases, only one or two spore stages could be found at the time of observation and there is no information of the alternate hosts. This is the first study of poplar rust disease to the species level in the area. Rust disease is likely to be the most important disease on poplar in this area. As poplar rust can cause severe damages to nursery plants and young trees, there must be further research to understand the epidemiology of the rust disease. A key question to be answered is whether the rust goes through a full life-cycle, possible via known alternate host Allium spp. or only uredinial and telial stages are present in the studied area.

This study aimed to investigate the associations of parental cancer with IQ, stress resilience, and physical fitness of the affected men during early adulthood. Materials and methods: In this Swedish population-based study, we included 465,249 men born during 1973–1983 who underwent the military conscription examination around the age of 18 years. We identified cancer diagnoses among the parents of these men from the Cancer Register. IQ, stress resilience, and physical fitness of the men were assessed at the time of conscription and categorized into three levels: low, moderate, and high (reference category. We used multinomial logistic regression to assess the studied associations. Results: Overall, parental cancer was associated with higher risks of low stress resilience (relative risk ratio [RRR]: 1.09 [95% confidence interval (CI 1.04–1.15] and low physical fitness (RRR: 1.12 [95% CI 1.05–1.19]. Stronger associations were observed for parental cancer with a poor expected prognosis (low stress resilience: RRR: 1.59 [95% CI 1.31–1.94]; low physical fitness: RRR: 1.45 [95% CI 1.14–1.85] and for parental death after cancer diagnosis (low stress resilience: RRR: 1.29 [95% CI 1.16–1.43]; low physical fitness: RRR: 1.40 [95% CI 1.23–1.59].

    Inulin, a group of dietary fibers, is reported to improve the metabolic disorders. In the present study, we investigated the effects of chicory inulin on serum metabolites of uric acid (UA), lipids, glucose, and abdominal fat deposition in quail model induced by a purine-rich diet. In this study, 60 male French quails were randomly allocated to five groups: CON (control group), MOD (model group), BEN (benzbromarone-treated group), CHI-H (high-dosage chicory inulin-treated group), and CHI-L (low-dosage chicory inulin-treated group). The serum UA level was significantly increased in the model group from days 7 to 28, as well as triglyceride (TG) and free fatty acid (FFA) increased later in the experimental period. The abdominal fat ratio was increased on day 28. Benzbromarone can decrease UA levels on days 14 and 28. The high and low dosage of chicory inulin also decreased serum UA levels on days 7, 14, and 28. The abdominal fat ratio, activity, and protein of acetyl-CoA carboxylase (ACC) were decreased in chicory inulin-treated groups. The activities of xanthine oxidase (XOD) and fatty acid synthase (FAS) were increased in the model group and decreased in the benzbromarone and chicory inulin groups. This study evaluated a quail model of induced hyperuricemia with other metabolic disorders caused by a high-purine diet. The results indicated that a purine-rich diet might contribute to the development of hyperuricemia, hypertriglyceridemia, and abdominal obesity. Chicory inulin decreased serum UA, TG, and abdominal fat deposition in a quail model of hyperuricemia by altering the ACC protein expression and FAS and XOD activities.

Cardiolipin (CL-conjugated LIP carrying CRM (CRM-CL/LIP and also carrying NGF (NGF-CL/LIP were used with AD models of SK-N-MC cells and Wistar rats after an insult with β-amyloid peptide (Aβ. We found that CRM-CL/LIP inhibited the expression of phosphorylated p38 (p-p38, phosphorylated c-Jun N-terminal kinase (p-JNK, and p-tau protein at serine 202 and prevented neurodegeneration of SK-N-MC cells. In addition, NGF-CL/LIP could enhance the quantities of p-neurotrophic tyrosine kinase receptor type 1 and p-extracellular signal-regulated kinase 5 for neuronal rescue. Moreover, WGA-grafted CRM-CL/LIP and WGA-grafted NGF-CL/LIP significantly improved the permeation of CRM and NGF across the blood–brain barrier, reduced Aβ plaque deposition and the malondialdehyde level, and increased the percentage of normal neurons and cholinergic activity in the hippocampus of AD rats. Based on the marker expressions and in vivo evidence, current LIP carriers can be promising drug delivery systems to protect nervous tissue against Aβ-induced apoptosis in the brain during the clinical management of AD.

  19. The role of ice particles in the microphysics and dynamics of deep convective storms in various latitudes (United States)

    Huang, Y. C.; Wang, P. K.


    The role of ice particles in the microphysics and dynamics of deep convective storms in various latitudes Yi-Chih Huang and Pao K. Wang Ice particles contribute to the microphysics and dynamics of severe storms in various regions of the world to a degree that is not commonly recognized. This study is motivated by the need to understand the role of ice particles plays in the development of severe storms so that their impact on various aspects of the storm behavior can be properly assessed. In this study, we perform numerical simulations of thunderstorms using a cloud resolving model WISCDYMM that includes parameterized microphysical processes to understand the role played by ice processes. We simulate thunderstorms occurred over various regions of the world including tropics, substropics and midlatitudes. We then perform statistical analysis of the simulated results to show the formation of various categories of hydrometeors to reveal the importance of ice processes. We will show that ice hydrometeors (cloud ice, snow, graupel/hail) account for 80% of the total hydrometeor mass for the High Plains storms but 50% for the subtropical storms. In addition, the melting of large ice particles (graupel and hail) is the major production process of rain in tropical storms although the ratio of ice-phase mass is responsible for only 40% of the total hydrometeor mass. Furthermore, hydrometeors have their own special microphysical processes in development and depletion over various latitudes. Microphysical structures depend on atmospheric dynamical and thermodynamical conditions which determine the partitioning of hydrometeors. This knowledge would benefit the microphysics parameterization in cloud models and cumulus parameterization in global circulation models.

  20. Determining Adequate Averaging Periods and Reference Coordinates for Eddy Covariance Measurements of Surface Heat and Water Vapor Fluxes over Mountainous Terrain

    Directory of Open Access Journals (Sweden)

    Yi-Ying Chen Ming-Hsu Li


    Full Text Available Two coordinate rotation approaches (double and planar-fit rotations and no rotation, in association with averaging periods of 15 - 480 min, were applied to compute surface heat and water vapor fluxes using the eddy covariance approach. Measurements were conducted in an experimental watershed, the Lien-Hua-Chih (LHC watershed, located in central Taiwan. For no rotation and double rotation approaches, an adequate averaging period of 15 or 30 min was suggested for better energy closure and small variations on energy closure fractions. For the planar-fit rotation approach, an adequate averaging period of 60 or 120 min was recommended, and a typical averaging period of 30 min is not superior to that of 60 or 120 min in terms of better energy closure and small variations on energy closure fractions. The Ogive function analysis revealed that the energy closure was improved with the increase of averaging time by capturing sensible heat fluxes at low-frequency ranges during certain midday hours at LHC site. Seasonal variations of daily energy closure fractions, high in dry season and low in wet season, were found to be associated with the surface dryness and strength of turbulent development. The mismatching of flux footprint areas among flux sensors was suggested as the cause of larger CF variations during the dry seasons as that indicated by the footprint analysis showing scattered source areas. During the wet season, the underestimation of turbulent fluxes by EC observations at the LHC site was attributed to weak turbulence developments as the source area identified by the footprint analysis was closer to the flux tower than those scattered in dry season.

Tuberculous brain abscess usually occurs in an immunocompromised host. Almost all previously documented cases have involved acquired immune deficiency syndrome. We encountered a 53-year-old right-handed immunocompetent male who was initially suspected of having a cerebrovascular accident due to acute-onset right hemiparesis and paresthesia. A tentative diagnosis of brain tumor versus brain abscess was made on imaging studies. The patient was finally diagnosed with a tuberculous brain abscess based upon deterioration on imaging and a positive tuberculosis culture. The tuberculous brain abscess was located in the left parietal lobe, which resulted in Gerstmann's syndrome and right-sided apraxia. Stereotactic surgery was performed. He was also given antituberculosis chemotherapy and comprehensive rehabilitation. Considerable improvement was noted after rehabilitation. The patient even returned to a normal life and work. Our case demonstrates that an aggressive intensive inpatient rehabilitation program combined with stereotactic surgery and effective antituberculosis therapy play an important role in improving the outcome for patients with tuberculous brain abscess, Gerstmann's syndrome, and right-sided apraxia.Keywords: tuberculous brain abscess, Gerstmann's syndrome, rehabilitation

    We present the first observation, analysis, and modeling of solar coronal twin jets, which occurred after a preceding jet. Detailed analysis on the kinetics of the preceding jet reveals its blowout-jet nature, which resembles the one studied in Liu et al. However, the erupting process and kinetics of the twin jets appear to be different from the preceding one. Lacking detailed information on the magnetic fields in the twin jet region, we instead use a numerical simulation using a three-dimensional (3D) MHD model as described in Fang et al., and find that in the simulation a pair of twin jets form due to reconnection between the ambient open fields and a highly twisted sigmoidal magnetic flux, which is the outcome of the further evolution of the magnetic fields following the preceding blowout jet. Based on the similarity between the synthesized and observed emission, we propose this mechanism as a possible explanation for the observed twin jets. Combining our observation and simulation, we suggest that with continuous energy transport from the subsurface convection zone into the corona, solar coronal twin jets could be generated in the same fashion addressed above.

  4. Charge Transfer Processes in Collisions of Si4+ Ions with He Atoms at Intermediate Energies (United States)

    Suzuki, R.; Watanabe, A.; Sato, H.; Gu, J. P.; Hirsch, G.; Buenker, R. J.; Kimura, M.; Stancil, P. C.

    Charge transfer in collisions of Si4+ ions with He atoms below 100 keV/u is studied by using a molecular orbital representation within both the semiclassical and quantal representations. Single transfer reaction Si4++He →Si3++He+ has been studied by a number of theoretical investigations. In addition to the reaction (1), the first semiclassical MOCC calculations are performed for the double transfer channel Si4++HE→Si2++He2+ Nine molecular states that connect both with single and double electron transfer processes are considered in the present model. Electronic states and corresponding couplings are determined by the multireference single- and double- excitation configuration interaction method. The present cross sections tie well with the earlier calculations of Stancil et al., Phys. Rev. A 55, 1064 (1997) at lower energies, but show a rather different magnitude from those of Bacchus-Montabonel and Ceyzeriat, Phys. Rev. A 58, 1162 (1998). The present rate constant is found to be significantly different from the experimental finding of Fang and Kwong, Phys. Rev. A 59, 342 (1996) at 4,600 K, and hence does not support the experiment.

  5. Tropical House Gecko (Hemidactylus mabouia predation on brown spiders (Loxosceles intermedia

    Directory of Open Access Journals (Sweden)

    E.N. Ramires


    Full Text Available Brown spiders (Loxosceles spp. are venomous arachnids, successfully adapted to urban habitats in Brazil. Loxoscelism became a serious public health problem in Paraná State, especially at the capital Curitiba, where the most abundant species is Loxosceles intermedia. Hemidactylus mabouia (Gekkonidae lizards are synanthropic predators of arthropods. In this paper, we describe the predatory behavior of the Tropical House Gecko H. mabouia on L. intermedia under laboratory conditions. Twelve geckos were observed, and all of them fed on brown spiders (n=123 observations. The attack consisted of a fast run followed by one bite on the spider’s abdomen or legs. The geckos did not attack L. intermedia anterior body parts, probably due to the fangs present in this region. Two Hemidactylus individuals were killed by L. intermedia bites: during a predatory encounter, and by an induced bite on a restrained lizard. The observations summarized in this paper show that H. mabouia could be used in the biological control of Loxosceles populations in human dwellings. However, additional field studies are necessary to quantify the impact of H. mabouia predation on urban populations of L. intermedia and other species of the same genus.

  6. Medical Evacuation from Vietnam of an Elderly with Tuberculosis Spondylitis

    Directory of Open Access Journals (Sweden)

    Ying-Hua Shieh


    Full Text Available Despite the growth in economy in Vietnam, the infrastructure of dependable medical care is still lacking. Therefore, aeromedical evacuation of patients to other countries for further medical interventions has become an important medical service in the region. We report a case where an elderly man who was aeromedically evacuated from Ho Chi Minh City, Vietnam to Taipei Medical University–Municipal Wan Fang Hospital in Taipei, Taiwan. The patient developed a sudden onset of quadriplegia because of an epidural abscess at the cervical spine C6–C7. Antituberculous medication was prescribed for suspected tuberculous spondylitis, because his cerebral spinal fluid showed elevated white blood cells with a predominance of lymphocytes, and mildly elevated total protein. However, whole body tumor scan (67Ga mCi and whole body bone scan (99mTc methylene diphosphonate, 25 mCi did not reveal any specific results. Surgical intervention was arranged because of cervical spine instability and the need for a diagnostic biopsy. Adenocarcinoma of the prostate was found incidentally and was treated with bilateral orchiectomy and radiation therapy. This was the first medical evacuation by the Family Medical Practice group in Ho Chi Minh City, Vietnam to Taiwan.

  7. Differential Visual Processing of Animal Images, with and without Conscious Awareness. (United States)

    Zhu, Weina; Drewes, Jan; Peatfield, Nicholas A; Melcher, David


    The human visual system can quickly and efficiently extract categorical information from a complex natural scene. The rapid detection of animals in a scene is one compelling example of this phenomenon, and it suggests the automatic processing of at least some types of categories with little or no attentional requirements (Li et al., 2002, 2005). The aim of this study is to investigate whether the remarkable capability to categorize complex natural scenes exist in the absence of awareness, based on recent reports that "invisible" stimuli, which do not reach conscious awareness, can still be processed by the human visual system (Pasley et al., 2004; Williams et al., 2004; Fang and He, 2005; Jiang et al., 2006, 2007; Kaunitz et al., 2011a). In two experiments, we recorded event-related potentials (ERPs) in response to animal and non-animal/vehicle stimuli in both aware and unaware conditions in a continuous flash suppression (CFS) paradigm. Our results indicate that even in the "unseen" condition, the brain responds differently to animal and non-animal/vehicle images, consistent with rapid activation of animal-selective feature detectors prior to, or outside of, suppression by the CFS mask.

    Deng, Wei; Li, Le; Wang, Zixia; Chang, Xiaonan; Li, Rui; Fang, Ziye; Wei, Dang; Yao, Liang; Wang, Xiaoqin; Wang, Qi; An, Guanghui


    To evaluate/assess the quality of the Clinical Practice Guidelines (CPGs) of traditional medicine in China. We systematically searched the literature databases WanFang Data, VIP, CNKI and CBM for studies published between 1978 and 2012 to identify and select CPGs of traditional medicine. We used the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument to evaluate these guidelines. A total of 75 guidelines were included, of which 46 guidelines (62%) were on Traditional Chinese Medicine, 19 (25%) on Chinese Integrated Medicine, and 10 (13%) on Uyghur Medicine. Most traditional medicine CPGs published in domestic journals scored medicine. In each domain of AGREE II, traditional Medicine CPGs performed clearly better than international CPGs. The same trend was seen in guidelines of Modern Medicine. An increasing amount of CPGs are being published, but their quality is low. Referring to the key points of international guidelines development, supervision through AGREE II, cooperating with international groups and exploring the strategy of guideline development could improve the quality of CPGs on traditional medicine.

    Zhang, Yuanyuan; Qian, Yan; Wu, Juemin; Wen, Fule; Zhang, Yaqing


    Newly graduated nurses suffer from occupational stress during the transition from school to employment as a result of inadequacy, interpersonal relationships, and the overwhelming workload. Mentoring programs have proved effective in facilitating this transition. To evaluate the effectiveness of a mentoring program on the mentor, mentee, and organization. The Cochrane Library, Medline, Ovid, Elsevier, Embase, CINAHL, CBM, CNKI, and WanFang Data databases were searched to identify relevant publications in English or Chinese up to October 2014. This is a systematic review. This review identified nine potentially eligible studies, and the methodological quality levels of the included studies were all ranked as level B. These studies revealed that the turnover rate can be decreased through a mentoring program. Additionally, mentoring can enhance nursing competency and establish a supportive workforce environment, resulting in positive outcomes. This review reveals that a mentoring program has positive effects on the mentors, mentees, and organizations. A successful mentorship program should include rigorous mentor selection and adequate training. Additionally, potential barriers such as time constraints and scheduling limitations should be taken into consideration during implementation. Copyright © 2015 Elsevier Ltd. All rights reserved.

  12. On the Observation and Simulation of Solar Coronal Twin Jets (United States)

    Liu, Jiajia; Fang, Fang; Wang, Yuming; McIntosh, Scott W.; Fan, Yuhong; Zhang, Quanhao


    We present the first observation, analysis, and modeling of solar coronal twin jets, which occurred after a preceding jet. Detailed analysis on the kinetics of the preceding jet reveals its blowout-jet nature, which resembles the one studied in Liu et al. However, the erupting process and kinetics of the twin jets appear to be different from the preceding one. Lacking detailed information on the magnetic fields in the twin jet region, we instead use a numerical simulation using a three-dimensional (3D) MHD model as described in Fang et al., and find that in the simulation a pair of twin jets form due to reconnection between the ambient open fields and a highly twisted sigmoidal magnetic flux, which is the outcome of the further evolution of the magnetic fields following the preceding blowout jet. Based on the similarity between the synthesized and observed emission, we propose this mechanism as a possible explanation for the observed twin jets. Combining our observation and simulation, we suggest that with continuous energy transport from the subsurface convection zone into the corona, solar coronal twin jets could be generated in the same fashion addressed above.

    Lin FY


    Full Text Available Fang-Yi Lin, Jiin-Ru Rong, Tzu-Ying Lee Department of Nursing, School of Nursing, National Taipei University of Nursing and Health Sciences, Taipei, Taiwan, Republic of China Abstract: The purpose of this concept analysis is to uncover the essential elements involved in caregivers' resilience in the context of caring for children with chronic conditions. Walker and Avant's methodology guided the analysis. The study includes a literature review of conceptual definitions of caregiver resilience in caring for children with chronic conditions. The defining attributes and correlates of caregiver resilience are reviewed. Concept analysis findings in a review of the nursing and health-related literature show that caregiver resilience in the context of caring for chronically ill children can be defined within four main dimensions, ie, disposition patterns, situational patterns, relational patterns, and cultural patterns. Empiric measurements of the impact of caregiver resilience applied to caregivers with children with chronic conditions are also reported in the analysis. The findings of this concept analysis could help nurses and health care providers to apply the concept of caregiver resilience in allied health care and be applied to further studies.

    Chinese ancient porcelain history has lasted about three thousands years from Shang Dynasty (1100∼1600 BC). A large amount of ancient porcelain sherds with accuracy provenance and ages were excavated from a lot of kiln sites in China. Archaeologists and ceramic experts have recognized and researched it with excavated stratum, utensil shape, body quality, glaze color and painting pattern. However, the appearance characteristic of some ancient porcelain manufactured in different kilns is similar. Therefore, it is still difficult to identify the provenance and ages of the samples excavated from some sites using traditional methods. Up, to now, many problems of Chinese ancient porcelain are confused for archaeologist and collecting experts. The elemental composition of ancient porcelain shows certain information of provenance and age. Especially, the sorts and contents of the elements in porcelain didn't change, so it is very useful to determine the provenance of ancient porcelain with elemental composition characteristics. Provenance characteristic is the important scientific information to identify ancient porcelain wares excavated from sites and graves. The porcelain samples of Si-Long-Kou Yue kiln in Zhejiang Province of china have been analyzed with NAA in this paper. The provenance characteristic was compared with it of Hong-Zhou kiln of Jiang-Xi Province and Yao-Zhou kiln of Shan-Xi Province. The experimental data were studied with statistic methods. The results show that the chemical compositions of porcelain body samples for three kilns were different. The difference was been able identified. The porcelain body materials of both Si-Long-Kou Yue kiln and Hong-Zhou kiln of Jiang-Xi were similar. The samples of Yao-Zhou kiln in north of China existed obvious difference.

  15. “六艺”中的“射艺教育”

    Institute of Scientific and Technical Information of China (English)



    “射艺”是西周时期六艺教育的重要内容。夏商时期“射艺”教育萌芽并初步发展,出现了专门教习射艺的场所及特定专职人员。西周时期国家大事“惟祀与戎”,射艺教育被赋予了新的内容,更加强调了礼乐教化和军事训练的功能,除了礼乐教化的作用外,也在于使贵族阶级的射箭水平有所提高,以备战场上的需要,深层意义上也是为军事的需要而服务的。%ABSTRACT:The “Archery Art” was one of the important contents of the “Six Arts” education in the Western Zhou Dynasty. During the Xia and Shang Dynasties the “Archery Art” emerged and had initial development, and the special grounds for teaching and practicing archery and special archery educational personnel were set. In the Western Zhou Dynasty, “the most important national affairs were nothing but the sacriifce and warfare”, and the archery education was assigned new contents; in addition to the ritual and etiquette functions, the archery education also raised the ifghting abilities of the elite classes to prepare for the battles, therefore its in-depth importance was to meet the military demands.

  16. Homeopathy: meta-analyses of pooled clinical data. (United States)

    Hahn, Robert G


    In the first decade of the evidence-based era, which began in the mid-1990s, meta-analyses were used to scrutinize homeopathy for evidence of beneficial effects in medical conditions. In this review, meta-analyses including pooled data from placebo-controlled clinical trials of homeopathy and the aftermath in the form of debate articles were analyzed. In 1997 Klaus Linde and co-workers identified 89 clinical trials that showed an overall odds ratio of 2.45 in favor of homeopathy over placebo. There was a trend toward smaller benefit from studies of the highest quality, but the 10 trials with the highest Jadad score still showed homeopathy had a statistically significant effect. These results challenged academics to perform alternative analyses that, to demonstrate the lack of effect, relied on extensive exclusion of studies, often to the degree that conclusions were based on only 5-10% of the material, or on virtual data. The ultimate argument against homeopathy is the 'funnel plot' published by Aijing Shang's research group in 2005. However, the funnel plot is flawed when applied to a mixture of diseases, because studies with expected strong treatments effects are, for ethical reasons, powered lower than studies with expected weak or unclear treatment effects. To conclude that homeopathy lacks clinical effect, more than 90% of the available clinical trials had to be disregarded. Alternatively, flawed statistical methods had to be applied. Future meta-analyses should focus on the use of homeopathy in specific diseases or groups of diseases instead of pooling data from all clinical trials. © 2013 S. Karger GmbH, Freiburg.

Recently, we have introduced alkyne-terminated poly(amidoamine (PAMAM dendrons of different generations (G=2,3 into chitosan to obtain dendronized chitosan derivatives [Cs-g-PAMAM (G=2,3], which exhibited a better water solubility and enhanced plasmid DNA transfection efficiency. In this study, we attempted to examine the impact of Cs-g-PAMAM (G=2,3 at different concentrations (25 µg/mL, 50 µg/mL, and 100 µg/mL on the morphology, surface structure, and viability of rat red blood cells (RBCs. The results showed that treatment of RBCs with Cs-g-PAMAM (G=2,3 at 50 µg/mL and 100 µg/mL induced a slightly higher hemolysis than Cs, and Cs-g-PAMAM (G=3 caused a slightly higher hemolysis than Cs-g-PAMAM (G=2, but all values were <5.0%. Optical microscopic and atomic force microscopic examinations indicated that Cs-g-PAMAM (G=2,3 caused slight RBC aggregation and lysis. Treatment of RBCs with 100 µg/mL Cs-g-PAMAM (G=3 induced echinocytic transformation, and RBCs displayed characteristic irregular contour due to the folding of the periphery. Drephanocyte-like RBCs were observed when treated with 100 µg/mL Cs-g-PAMAM (G=3. Erythrocytes underwent similar shape transition upon treatment with Cs-g-PAMAM (G=2 or Cs. The roughness values (Rms of RBCs incubated with Cs-g-PAMAM (G=2,3 were significantly larger

  19. Potential Magma Chambers beneath the Tatun Volcanic Area, Taiwan: Results from Magnetotelluric Survey and Monitoring (United States)

    Chen, C.


    Previous earthquakes analysis indicated existing seismicity anomaly beneath Tatun volcano, Taiwan, possibly caused by the fluid activity of the volcano. Helium isotope studies also indicated that over 60% of the fumarolic gases and vapors originated from deep mantle in the Tatun volcano area. The chemistry of the fumarolic gases and vapors and seismicity anomaly are important issues in view of possible magma chamber in the Tatun volcano, where is in the vicinity of metropolitan Taipei, only 15 km north of the capital city. In this study magnetotelluric (MT) soundings and monitoring were deployed to understand the geoelectric structures in the Tatun volcano as Electromagnetic methods are sensitive to conductivity contrasts and can be used as a supplementary tool to delineate reservoir boundaries. An anticline extending more than 10 km beneath the Chih-Shin-Shan and Da-You-Kan areas was recognized. Low resistivity at a shallow and highly porous layer 500m thick might indicate circulation of heated water. However, a high resistivity layer at depth between 2 and 6 km was detected. This layer could be associated with high micro-earthquakes zone. The characteristics of this layer produced by either the magma chamber or other geothermal activity were similar to that of some other active volcanic areas in the world. At 6 km underground was a dome structure of medium resistivity. This structure could be interpreted as a magma chamber in which the magma is possibly cooling down, as judged by its relatively high resistivity. The exact attributes of the magma chamber were not precisely determined from the limited MT soundings. At present, a joint monitors including seismic activity, ground deformation, volcanic gases, and changes in water levels and chemistry are conducted by universities and government agencies. When unusual activity is detected, a response team may do more ground surveys to better determine if an eruption is likely.

  1. A Study on New Pochonka Published in A.D. 1792 (United States)

    Ahn, Sang-Hyeon


    New Pochonka published in the eighteenth century of the Choson dynasty was composed of star-charts based on the new observations made by Jesuits in China and songs corrected a little bit from previous version of Pochonka. The asterisms in the previous Pochonka are listed in the same order to that in the Song dynasty's literature; while the asterisms in the new Pochonka are listed in accordance with Pu-tien-ko published in China after the Ming dynasty. The Chinese-style twelve-equatorial-section system is adopted in the new Pochonka, while in its song is adopted the zodiac system, which can be seen in the star-charts of previous version of Pochonka. The asterisms belonging to three or four neighboring lunar-mansions are drawn in one chart. Each chart covers asterisms not belonging to a certain range of right ascension, but to a certain lunar mansion. We estimate the forming era of the new Pochonka from the following facts; that the Ling-Tai-I-Hsiang-Chih was used to make charts and footnotes whose archetype can be found in the Chinese literature around A.D. 1700, that these Chinese books were imported into Choson in A.D. 1709, that the naming taboo to the emperor Khang-Hsi was used, that the order of Shen-Hsiu (參宿) was transposed with Tshui-Hsiu (자宿), and that the new Pochonka was substituted for the old version when the rules of Royal Astronomical Bureau was reformed in A.D. 1791. In conclusion, the parent sources of the charts and footnotes of the new Pochonka might be imported from the Ching dynasty around 1709 A.D. to form the new Pochonka between A.D. 1709 and A.D. 1791, and finally to be published in A.D. 1792. We discuss the possible future works to make a firm conclusion.

To prepare the biodegradable nanofibrous membranes, poly(D,L-lactide-co-glycolide and the antibiotics were first dissolved in 1,1,1,3,3,3-hexafluoro-2-propanol. They were electrospun into biodegradable drug-eluting membranes, which were then enveloped on the surface of stainless plates. An elution method and a high-performance liquid chromatography assay were employed to characterize the in vivo and in vitro release rates of the antibiotics from the nanofiber-enveloped plates. The results showed that the biodegradable nanofiber-enveloped plates released high concentrations of vancomycin and ceftazidime (well above the minimum inhibitory concentration for more than 3 and 8 weeks in vitro and in vivo, respectively. A bacterial inhibition test was carried out to determine the relative activity of the released antibiotics. The bioactivity ranged from 25% to 100%. In addition, the serum creatinine level remained within the normal range, suggesting that the high vancomycin concentration did not affect renal function. By adopting the electrospinning technique, we will be able to manufacture biodegradable drug-eluting implants for the long-term drug delivery of different antibiotics.

  6. Genomic Organization, Phylogenetic Comparison and Differential Expression of the SBP-Box Family Genes in Grape (United States)

    Hou, Hongmin; Li, Jun; Gao, Min; Singer, Stacy D.; Wang, Hao; Mao, Linyong; Fei, Zhangjun; Wang, Xiping


    Background The SBP-box gene family is specific to plants and encodes a class of zinc finger-containing transcription factors with a broad range of functions. Although SBP-box genes have been identified in numerous plants including green algae, moss, silver birch, snapdragon, Arabidopsis, rice and maize, there is little information concerning SBP-box genes, or the corresponding miR156/157, function in grapevine. Methodology/Principal Findings Eighteen SBP-box gene family members were identified in Vitis vinifera, twelve of which bore sequences that were complementary to miRNA156/157. Phylogenetic reconstruction demonstrated that plant SBP-domain proteins could be classified into seven subgroups, with the V. vinifera SBP-domain proteins being more closely related to SBP-domain proteins from dicotyledonous angiosperms than those from monocotyledonous angiosperms. In addition, synteny analysis between grape and Arabidopsis demonstrated that homologs of several grape SBP genes were found in corresponding syntenic blocks of Arabidopsis. Expression analysis of the grape SBP-box genes in various organs and at different stages of fruit development in V. quinquangularis ‘Shang-24’ revealed distinct spatiotemporal patterns. While the majority of the grape SBP-box genes lacking a miR156/157 target site were expressed ubiquitously and constitutively, most genes bearing a miR156/157 target site exhibited distinct expression patterns, possibly due to the inhibitory role of the microRNA. Furthermore, microarray data mining and quantitative real-time RT-PCR analysis identified several grape SBP-box genes that are potentially involved in the defense against biotic and abiotic stresses. Conclusion The results presented here provide a further understanding of SBP-box gene function in plants, and yields additional insights into the mechanism of stress management in grape, which may have important implications for the future success of this crop.

    Full Text Available Huazhao Festival is a traditional one that is celebrated in early spring and appeals to both highbrows and lowbrows. Once, it was as significant as Lantern Festival and Mid-autumn Festival. Ever since Tang Dynasty, it has undergone stages of emerging, thriving, declining and restoring. Originally, people only had a spring outing enjoying beautiful flowers at this festival; later, various other folk activities were also carried out on this day, including catching butterflies, picking wild vegetables, offering sacrifices to gods, predicting bumper and poor harvest, fastening strips of red cloth to stems of flowers and trees (shang hong, having competitions on grass, encouraging agriculture, holding and attending banquets, writing articles, paying court and so on. These activities demonstrated such characteristics of the national culture of China as elegance, harmony and life-friendliness. Obviously different from other traditional festivals like Spring Festival, Mid-autumn Festival, Dragon Boat Festival, etc, Huazhao Festival has unique style and value. Despite its fading away from people’s life due to changes in modern society, its cultural glamour and comprehensive value still exist. Along with economic and social development and the increase of people’s spiritual and cultural demands, Huazhao Festival has regained people’s attention. It has been restored and hosted in some regions and identified as an intangible cultural heritage. By means of literature review, the folk customs of Huazhao Festival was re-presented to some extent in this paper. Its modern values in areas including health, culture, ecology and industry were analyzed. This paper is of certain significance, in respect of conserving and inheriting this national festival, promoting its restoration in more regions in a way more approximate to historical tradition and giving play to its unique role to benefit modern society.

  9. Myofibroblasts and their resistance to apoptosis: a possible mechanism of osteoradionecrosis

    Full Text Available Lei Tian,1 Li-Sheng He,1 Bhavesh Soni,2 Hong-Tao Shang11Department of Oral and Maxillofacial Surgery, School of Stomatology, Fourth Military Medical University, China; 2Maxillofacial Unit, Morriston Hospital, Swansea, Wales, UKAbstract: Osteoradionecrosis (ORN in the head and neck area is the most devastating long-term complication of radiotherapy, with slow progression and inability to heal spontaneously. ORN can lead to intolerable pain, fractures, and sequestration of devitalized bone and fistulae, making oral feeding impossible and causing facial deformation. In spite of its notorious reputation over at least 90 years, the precise pathogenesis of ORN has not been fully clarified, which has led to obstacles in the management of the disease. Several theories about its pathogenesis have been formulated, and radiation-induced fibrosis is the newest one. According to this theory, ORN is essentially a type of fibrosis induced by radiotherapy, and antifibrosis therapy has been shown to be effective in its treatment. We assumed that ORN, like fibrosis in other organs, is the result of a process of fibrogenesis in which myofibroblasts are the key effector cells. The uninterrupted accumulation of myofibroblasts and consequent persistent excess production of collagenous extracellular matrix and tensile force result in loss of normal function and ultimately radiation-induced fibrosis. During this process, myofibroblasts may be protected from apoptosis by acquiring an immune-privileged capacity, which allows continuous matrix synthesis. If this hypothesis proves to be correct, it would enable better understanding of the cellular and molecular mechanisms underlying the pathogenesis and progression of ORN, and would help improve our ability to prevent occurrence of ORN, give an earlier diagnosis, and treat it more effectively.Keywords: osteoradionecrosis, apoptosis, fibrosis, mandible, myofibroblast

  10. Evaluation of a micro-scale wind model's performance over realistic building clusters using wind tunnel experiments (United States)

    Zhang, Ning; Du, Yunsong; Miao, Shiguang; Fang, Xiaoyi


    The simulation performance over complex building clusters of a wind simulation model (Wind Information Field Fast Analysis model, WIFFA) in a micro-scale air pollutant dispersion model system (Urban Microscale Air Pollution dispersion Simulation model, UMAPS) is evaluated using various wind tunnel experimental data including the CEDVAL (Compilation of Experimental Data for Validation of Micro-Scale Dispersion Models) wind tunnel experiment data and the NJU-FZ experiment data (Nanjing University-Fang Zhuang neighborhood wind tunnel experiment data). The results show that the wind model can reproduce the vortexes triggered by urban buildings well, and the flow patterns in urban street canyons and building clusters can also be represented. Due to the complex shapes of buildings and their distributions, the simulation deviations/discrepancies from the measurements are usually caused by the simplification of the building shapes and the determination of the key zone sizes. The computational efficiencies of different cases are also discussed in this paper. The model has a high computational efficiency compared to traditional numerical models that solve the Navier-Stokes equations, and can produce very high-resolution (1-5 m) wind fields of a complex neighborhood scale urban building canopy (~ 1 km ×1 km) in less than 3 min when run on a personal computer.

    Gui Yang


    Full Text Available Objectives. Published data on resistin levels in patients with colorectal cancer (CRC were conflicting and heterogeneous. We conducted a meta-analysis of observational studies to examine the association of circulating resistin levels with carcinogenesis of the CRC. Methods. Potentially eligible studies published up to November 2015 were searched through MEDLINE, EMBASE, Science Citation Index Expanded database, CNKI, and WanFang database. The pooled weighted mean differences (WMDs with 95% confidence intervals (CIs calculated by fixed- or random-effect model were used to estimate the effects. Results. A total of 11 studies involving 965 patients were admitted in our meta-analysis. The pooled effects indicated that resistin levels were higher in CRC patients compared to healthy controls (WMD: 1.47 ng/mL; 95% CI: 0.78 to 2.16, with significant heterogeneity across the studies (I2=72%, p<0.0001. Subgroup analyses and sensitivity analyses revealed that study quality, design, sample type, and resistin assays may account for this heterogeneity. No publication bias was observed. Conclusions. Our meta-analysis suggests that increased circulating resistin levels are associated with greater risk of colorectal cancer. Given the limited number of available studies and significant heterogeneity, larger well-designed randomized studies are warranted.

  12. Overproduction of Upper-Layer Neurons in the Neocortex Leads to Autism-like Features in Mice

    Directory of Open Access Journals (Sweden)

    Wei-Qun Fang


    Full Text Available Summary: The functional integrity of the neocortex depends upon proper numbers of excitatory and inhibitory neurons; however, the consequences of dysregulated neuronal production during the development of the neocortex are unclear. As excess cortical neurons are linked to the neurodevelopmental disorder autism, we investigated whether the overproduction of neurons leads to neocortical malformation and malfunction in mice. We experimentally increased the number of pyramidal neurons in the upper neocortical layers by using the small molecule XAV939 to expand the intermediate progenitor population. The resultant overpopulation of neurons perturbs development of dendrites and spines of excitatory neurons and alters the laminar distribution of interneurons. Furthermore, these phenotypic changes are accompanied by dysregulated excitatory and inhibitory synaptic connection and balance. Importantly, these mice exhibit behavioral abnormalities resembling those of human autism. Thus, our findings collectively suggest a causal relationship between neuronal overproduction and autism-like features, providing developmental insights into the etiology of autism. : Fang et al. generated a mouse model with excessive excitatory neurons in the neocortex by manipulating embryonic neurogenesis. Overproduction of neurons results in autism-like anatomical and behavioral features. These findings suggest a causal relationship between overproduction of neurons and cortical malfunction and provide developmental insights into the etiology of autism.

    Sun, Fengmei; Zhang, Juan; Pu, Yuepu


    This study is designed to perform a meta-analysis and trial sequential analysis (TSA) to investigate whether people with G6PD deficiency suffered less malarial infection. We searched from PubMed, Science Direct, Springer Link, CNKI, and Wan Fang databases for case-control study, cohort study or cross section study until April 2017. TSA was used to determine the state of evidence and calculate the required sample size. Eight case-control studies and five cross-sectional studies (30,683participants) were included in this meta-analysis. Compared with normal control group, we found significant protection from severe malaria (OR 0.644, 95% CI [0.493-0.842]; P=0.001) among people with decreasing G6PD activity. People with variations of G6PD gene at nucleotide 202(G6PD A-) were also found to be associated with resistance on severe malaria pooled (OR 0.851, 95% CI [0.779-0.930]; P =0.0001). Sex-stratified test suggested that protection of severe malaria is conferred to both G6PD A-males and heterozygous females (with a single copy of the variant). In conclusion, our study found a significant protection from severe malaria among G6PD deficient people compared to the

  16. The development and impact of primary health care in China from 1949 to 2015: A focused review. (United States)

    Li, Huazhang; Liu, Kun; Gu, Jianjun; Zhang, Yimin; Qiao, Yun; Sun, Xiaoming


    High-quality primary health care (PHC) services are associated with better health outcomes and positive health equity. Providing PHC services to all inhabitants is one of the Chinese government's health care objectives. However, an imbalance between people's increasing health needs and effective health service utilization exists in China. The objective of this review is to identify evidence for PHC development in China and to summarize the challenges as a reference for the future improvement of China's PHC system. Literature searches related to China's PHC were performed in PubMed, Web of Science, China National Knowledge Infrastructure, and Wan-fang databases. Related data were collected from the China Statistical Yearbook on Health and Family Planning 2003-2016, the China National Health Accounts Report 2015, and An Analysis Report of National Health Services Survey in China, 2013. The PHC network and the population's health have improved in China in recent years, with general practitioners as "gatekeepers" who have gradually taken the initiative to offer health services to residents. The limitation of input and shortages of resources and skilled health care providers may restrict the sustainable development of China's PHC system. Therefore, policy support from the government is necessary. Copyright © 2017 John Wiley & Sons, Ltd.

  17. Evaluation of stability and viscosity measurement of emulsion from oil from production in northern oilfield in Thailand (United States)

    Juntarasakul, O.; Maneeintr, K.


    Emulsion is normally present in oil due to the mixing occurring during oil recovery. The formation of emulsion can cause some problems in production and transportation. Viscosity and stability of emulsion play a key roles in oil transportation and separation to meet sales specification. Therefore, the aims of this research are to measure the viscosity of oil an emulsion and to evaluate the stability of emulsion of light oil from Fang oilfield in Thailand. The parameters of this study are temperature, shear rate and water cut ranging from 50 to 80 °C, 3.75 to 70 s-1 and 0 to 60%, respectively. These effects of parameters on viscosity and stability of emulsion are required for the design of the process and to increase oil production with various conditions. The results shows that viscosity decreases as temperature and shear rate increase. In contrast, viscosity becomes higher when water cut is lower. Furthermore, droplet sizes of water-in-oil emulsion at different conditions are investigated the stability of emulsion. The droplet sizes become smaller when high shear rate is applied and emulsion becomes more stable. Furthermore, correlations are developed to predict the viscosity and stability of the oil and emulsion from Thailand.

    Meng, Hao; Xu, Jun; Pan, Chenling; Cheng, Jiaxing; Hu, Yue; Hong, Yin; Shen, Yuehai; Dai, Hua


    The objective of this study was to investigate cognitive dysfunction in 24-60-year-old neuromyelitis optica (NMO) patients, demographically matched healthy subjects, and MS patients. We conducted a comprehensive literature review of the PubMed, Medline, EMBASE, CNKI, Wan Fang Date, Web of Science, and Cochrane Library databases from inception to May 2016 for case-control studies that reported cognitive test scores in NMO patients, healthy subjects, and MS patients. Outcome measures were cognitive function evaluations, including performance on attention, language, memory, information processing speed, and executive function tests. The meta-analysis included eight studies. NMO patients performed significantly worse on attention (P < 0.00001), language (P = 0.00008), memory (P = 0.00004), information processing speed (P < 0.00001), and executive function tests (P = 0.00009) than healthy subjects. There were no significant differences in performance between NMO patients and MS patients on these tests. This meta-analysis indicates that NMO patients aged 24-60 years have significantly worse cognitive performance than demographically matched healthy subjects. However, this was comparable to the performance of demographically matched MS patients. There is a need for further rigorous randomized controlled trials with focus on elucidating the underlying mechanism of cognitive dysfunction in NMO patients.

Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards, and RevMan5 was used for data analysis. Results. 7 RCTs (545 patients were included and the methodological quality was evaluated as generally low. The pooled results showed that QKL combined with conventional treatment was more effective in effect rate, and the score of MESSS and TNF-α level compared with conventional treatment alone, but there was no significant difference in mortality of two groups. Only one trial reported routine life status. There were four trials reported adverse events, and no obvious adverse event occurred in three trials while one reported adverse events described as eruption and dizziness.

  1. Phylogeny and Historical Biogeography of Acer I-Study History of the Infrageneric Classification(1

    Directory of Open Access Journals (Sweden)

    Shing-Fan Huang


    Full Text Available Historical biogeography is a study of taxa in time and space including their origin, migration and diversification. This kind of study requires fossil data and an understanding of phylogenetic relationships. These requirements make Acer a good model to study because Acer 1 has a relatively complete fossil record, 2 contains many species, 3 is a major northern temperate floristic element, and 4 is well known. Because fossils are only confidently assigned to section or species group, section as a unit is suitable for tracing evolutionary history of Acer. However, the circumscription of section of Acer is different to each classification through the long history of studies. This work reviews and summarizes the studying history of Acer. Delendick in 1981concluded that the system of Ogata in 1967 and that of Jong in 1976 were superior to others except that most Jong’s series should be raised to section. This work, therefore, follows Delendick’s delineation of section except Distyla and Parviflora, which are combined as Parviflora, to elucidate the development of the circumscription of section based on the system of Pax in 1885 and 1886, Pojarkova in 1933, Momotani in 1962, Fang in 1966, Ogata in 1967, Murray in 1970, Jong in 1976, Delendick in 1990 and Xu in 1996.

    Full Text Available This is the first meta-analysis of the pooled prevalence of insomnia in the general population of China. A systematic literature search was conducted via the following databases: PubMed, PsycINFO, EMBASE and Chinese databases (China National Knowledge Interne (CNKI, WanFang Data and SinoMed. Statistical analyses were performed using the Comprehensive Meta-Analysis program. A total of 17 studies with 115,988 participants met the inclusion criteria for the analysis. The pooled prevalence of insomnia in China was 15.0% (95% Confidence interval [CI]: 12.1%-18.5%. No significant difference was found in the prevalence between genders or across time period. The pooled prevalence of insomnia in population with a mean age of 43.7 years and older (11.6%; 95% CI: 7.5%-17.6% was significantly lower than in those with a mean age younger than 43.7 years (20.4%; 95% CI: 14.2%-28.2%. The prevalence of insomnia was significantly affected by the type of assessment tools (Q = 14.1, P = 0.001. The general population prevalence of insomnia in China is lower than those reported in Western countries but similar to those in Asian countries. Younger Chinese adults appear to suffer from more insomnia than older adults.CRD 42016043620.

    Gliomas are the most common primary brain tumors. This meta-analysis aimed to systematically evaluate the relationship between CD147 expression in tissues and the clinicopathological features of patients with glioma. We searched PubMed (1966-2016), EMBASE (1980-2016), Cochrane Library (1996-2016), Web of Science (1945-2016), China National Knowledge Infrastructure (1982-2016), and Wan Fang databases (1988-2016). Quality assessment of the literature was performed using the Newcastle-Ottawa Scale, with Revman 5.3 and Stata 14.0 for analysis. In total, 1806 glioma patients from 19 studies were included, and patients with CD147 overexpression had poorer overall survival [hazard ratio (HR) = 2.211, P CD147 expression when comparing glioma tissues versus non-cancerous brain tissues (OR 20.42; 95% CI 13.94-29.91; P CD147 expression did not differ based on patient's age (young vs. old, P = 0.89) or gender (female vs. male, P = 0.57). CD147 expression may be a potential prognostic biomarker for poorer overall and relapse-free survival, and may affect the 5-year survival rate in glioma patients. CD147 expression is also closely correlated with poor clinical characteristics in glioma patients.

  4. Point-Counterpoint: Active surveillance for carriers of toxigenic Clostridium difficile should be performed to guide prevention efforts. (United States)

    McDonald, L Clifford; Diekema, Daniel J


    In 2017, we published a point-counterpoint on laboratory diagnosis of C. difficile infection (CDI). At that time, Drs Ferric Fang, Christopher Polage, and Mark Wilcox discussed the strategies for diagnosing Clostridium difficile colitis in symptomatic patients. Since that manuscript new guidelines from the Infectious Diseases Society of American and the Society for Health Care Epidemiology have been published (1) and healthcare systems have begun to explore screening asymptomatic patients for C. difficile colonization. The theory behind screening selected patient populations for C. difficile colonization is that these patients represent a substantial reservoir of the bacteria and can transfer the bacteria to other patients. Hospital administrators are taking note of institutional CDI rates because they are publicly reported. They have become an important metric impacting hospital safety ratings and value-based purchasing where hospitals may have millions of dollars of reimbursement at risk. In this point-counterpoint, Cliff McDonald, of the U.S. Centers for Disease Control and Prevention, will discuss the value of asymptomatic C. difficile screening, while Dan Diekema, of the University of Iowa, will discuss why caution should be used.

    Full Text Available This study compared proton pump inhibitors (PPIs and histamine H2 receptor antagonists (H2RAs for prevention of low-dose aspirin (LDA-related gastrointestinal (GI erosion, ulcer and bleeding. Electronic databases including PubMed, Embase, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, and WanFang Data were searched from the date of their establishment to December 31, 2013. Randomized controlled trials comparing PPIs and H2RAs for prevention of GI injury associated with low-dose aspirin (LDA were collected. Two reviewers independently abstracted studies and patient characteristics and appraised study quality using the Cochrane risk-of-bias tool. Meta-analysis was performed using RevMan 5.1 software. We included nine RCTs involving 1047 patients. The meta-analysis showed that PPIs were superior to H2RAs for prevention of LDA-associated GI erosion/ulcer [odds ratio (OR=0.28, 95% confidence interval (CI: 0.16-0.50] and bleeding (OR=0.28, 95% CI: 0.14-0.59. In conclusion, PPIs were superior to H2RAs for prevention of LDA-related GI erosion/ulcer and bleeding. Higher quality, large, multicenter RCTs are needed to demonstrate the preventive effect of the two acid-suppressive drugs.

  6. Photoexcited carrier trapping and recombination at Fe centers in GaN

    International Nuclear Information System (INIS)

    Uždavinys, T. K.; Marcinkevičius, S.; Leach, J. H.; Evans, K. R.; Look, D. C.


    Fe doped GaN was studied by time-resolved photoluminescence (PL) spectroscopy. The shape of PL transients at different temperatures and excitation powers allowed discrimination between electron and hole capture to Fe"3"+ and Fe"2"+ centers, respectively. Analysis of the internal structure of Fe ions and intra-ion relaxation rates suggests that for high repetition rates of photoexciting laser pulses the electron and hole trapping takes place in the excited state rather than the ground state of Fe ions. Hence, the estimated electron and hole capture coefficients of 5.5 × 10"−"8 cm"3/s and 1.8 × 10"−"8 cm"3/s should be attributed to excited Fe"3"+ and Fe"2"+ states. The difference in electron capture rates determined for high (MHz) and low (Hz) (Fang et al., Appl. Phys. Lett. 107, 051901 (2015)) pulse repetition rates may be assigned to the different Fe states participating in the carrier capture. A weak temperature dependence of the electron trapping rate shows that the potential barrier for the multiphonon electron capture is small. A spectral feature observed at ∼420 nm is assigned to the radiative recombination of an electron in the ground Fe"2"+ state and a bound hole.

    Sun, Kang; Wang, Le; Ma, Qingping; Cui, Qiaoyun; Lv, Qianru; Zhang, Wenzheng; Li, Xinghui


    Previous reports have suggested a potential association of tea consumption with the risk of osteoporosis. As such association is controversial, we conducted a meta-analysis to assess the relationship between tea consumption and osteoporosis. We systematically searched PubMed, EMBASE and WanFang databases until March 30, 2016, using the keywords "tea and osteoporosis," without limits of language. Odds ratios (ORs) with 95% confidence intervals (95% CIs) were derived by using random-effects models throughout the analyses. We conducted the analysis of the statistical heterogeneity using Cochrane I. The funnel plot was used to speculate the publication bias, while the subgroup analysis and multiround elimination method were employed. Our study was based on 17 journal articles, including 2 prospective cohort studies, 4 case-control studies, and 11 cross-sectional studies. In the present study, the total OR of osteoporosis for the highest versus the lowest categories of tea consumption was 0.62 (95% CI, 0.46-0.83), with significant heterogeneity among studies (I = 94%, P tea consumption and osteoporosis. Subgroup analysis showed that tea consumption could reduce the risk of osteoporosis in all examined subgroups. In the present study, it can be concluded from the results that tea consumption can reduce the risk of osteoporosis.

  8. Comment on 'Shang S. 2012. Calculating actual crop evapotranspiration under soil water stress conditions with appropriate numerical methods and time step. Hydrological Processes 26: 3338-3343. DOI: 10.1002/hyp.8405' (United States)

    Yatheendradas, Soni; Narapusetty, Balachandrudu; Peters-Lidard, Christa; Funk, Christopher; Verdin, James


    A previous study analyzed errors in the numerical calculation of actual crop evapotranspiration (ET(sub a)) under soil water stress. Assuming no irrigation or precipitation, it constructed equations for ET(sub a) over limited soil-water ranges in a root zone drying out due to evapotranspiration. It then used a single crop-soil composite to provide recommendations about the appropriate usage of numerical methods under different values of the time step and the maximum crop evapotranspiration (ET(sub c)). This comment reformulates those ET(sub a) equations for applicability over the full range of soil water values, revealing a dependence of the relative error in numerical ET(sub a) on the initial soil water that was not seen in the previous study. It is shown that the recommendations based on a single crop-soil composite can be invalid for other crop-soil composites. Finally, a consideration of the numerical error in the time-cumulative value of ET(sub a) is discussed besides the existing consideration of that error over individual time steps as done in the previous study.

    This study aimed to assess the effectiveness of Chinese medicine warm compress (CMWC) on back meridians in relieving cancer pain, reducing adjuvant analgesic doses and adverse reactions, and improving the quality of life (QOL). A total of 62 patients (age range 39-82 years) diagnosed with a malignant tumor and suffering from cancer-related pain were randomly divided into a treatment group (group A) and a control group (group B) (n = 31 for each). The patients in both groups were administered appropriate drugs for 2 cycles of 7-day treatments according to the World Health Organization (WHO) 3-step ladder for cancer pain relief in adults. In addition, a CMWC was given to patients in group A. Pain relief was assessed using the visual analogue scale (VAS) at various time points before and after interventions in each group. Alteration of analgesic doses, adverse reactions, performance status (PS), and QOL were evaluated and any differences between groups A and B evaluated. VAS scores at various time points after treatment were significantly decreased compared with the baseline level in group A. Overall response rate was significantly improved in group A compared with group B (70.97% vs 29.03%, P pain relief efficacy in various locations were found in group A after treatment vs before treatment (P pain with reduced doses, less adverse reactions, and improved QOL.

    Full Text Available A recent study showed that viewing manipulable objects such as images of tools induces the neural activation of posterior parietal areas. This neural activation is observed even when visual awareness of the image is visually suppressed. (Fang and He, 2005 Nature Neuroscience 10 1380–1385; Almeida et al, 2010 Psychological Science 21 772–778. However, the specific visuomotor information in tool images that drives the activation of dorsal areas is still unclear. We measured priming effect of invisible tool prime (left or right handed orientation. Observers distinguished the orientation of target tools (appropriate for left vs right handed grip briefly presented following visually suppressed primes (Experiment1. Also we measured the suppression time of tool images whose handle direction was presented in a left- or right-handed orientation. A dynamic noise pattern was presented to one of the observer's eyes at full contrast, while images of tools (left or right handed were simultaneously presented to the left or right visual field of the other eye. The subjects were asked to respond to the appearance of any partial or full part of the test image (Experiment 2. Results showed that (1 observers responded faster in the congruent condition (the same orientation between prime and target and (2 tool images shown in the right visual field took less time to gain dominance against the dynamic noise. These results suggest that even without overt recognition of presented tools, an object's affordance can be registered and processed in the brain. A recent study showed that viewing manipulable objects such as images of tools induces the neural activation of posterior parietal areas. This neural activation is observed even when visual awareness of the image is visually suppressed (Almeida et al., 2010 Psychological Science 21 772–778; Fang and He, 2005 Nature Neuroscience 10 1380–1385.

    This systematic review and meta-analysis of randomized controlled trials (RCTs) examined the efficacy and safety of adjunctive N-acetylcysteine (NAC), an antioxidant drug, in treating major depressive disorder (MDD), bipolar disorder, and schizophrenia. The PubMed, Cochrane Library, PsycINFO, CNKI, CBM, and WanFang databases were independently searched and screened by two researchers. Standardized mean differences (SMDs), risk ratios, and their 95% confidence intervals (CIs) were computed. Six RCTs (n = 701) of NAC for schizophrenia (three RCTs, n = 307), bipolar disorder (two RCTs, n = 125), and MDD (one RCT, n = 269) were identified and analyzed as separate groups. Adjunctive NAC significantly improved total psychopathology (SMD = -0.74, 95% CI: -1.43, -0.06; I 2 = 84%, P = 0.03) in schizophrenia, but it had no significant effect on depressive and manic symptoms as assessed by the Young Mania Rating Scale in bipolar disorder and only a small effect on major depressive symptoms. Adverse drug reactions to NAC and discontinuation rates between the NAC and control groups were similar across the three disorders. Adjunctive NAC appears to be a safe treatment that has efficacy for schizophrenia, but not for bipolar disorder or MDD. Further higher quality RCTs are warranted to determine the role of adjunctive NAC in the treatment of major psychiatric disorders. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Objective To evaluate the efficacy of nutrition therapy in alcoholic liver diseases (ALD. Methods PubMed, Embase, Web of Science, The Cochrane Central Register of Controlled Trials, Chinese Journals Full-Text Database, Chinese Biomedical Database and Wan Fang Digital Journal Full-Text Database were searched for relevant articles. Statistical analysis was performed by meta-analysis using Review Manager 5.1.0. Results Twelve randomized controlled trials including 508 cases were analyzed. Meta-analysis results were as follows: Compared with conventional therapy, nutrition therapy was more effective in reducing the serum total bilirubin (P=0.04 and alkaline phosphatase (P=0.04, and increasing serum transferrin (P<0.00001, but there was no statistically significant difference between the two groups in other liver functions and complications associated with ALD. There was no statistically significant difference between the two groups in the incidence of infection, short-term or long-term mortality of ALD. Conclusions Nutrition therapy can improve some important liver functions, such as serum total bilirubin, alkaline phosphatase, and transferrin in patients with ALD, but it may not improve the short-term or long-term mortality, other liver functions, or complications of ALD. Due to the above role in improving liver function, the nutrition therapy can be recommended as a routine treatment in patients with ALD. DOI: 10.11855/j.issn.0577-7402.2015.11.14

    Abstract  MANET is a group of wireless mobile that connected one to each other without fixed infrastructure so topology could change at anytime. MANET routing protocol has two models which are reactive routing protocol that built routing table only when needed and proactive routing protocol that maintain routing table periodically. General property which had to be satisfied by ad-hoc network protocol are route discovery, packet delivery and loop freedom. AODV is a reactive protocol in MANET that has time standard to determine how long a route is valid to be used (route validity so route discovery and packet delivery property should be satisfied in a specifically certain time. Protocol verification process done by modeling protocol specification using technique, tool and mathematic language. In this research protocol modeled using timed automata which is a modeling language that could be used to model a time dependent system in each process. Verification using timed automata can automatically done by UPPAAL tool model checker. Protocol which will be verified are AODV Break Avoidance by Ali Khosrozadeh et al. and AODV Reliable Delivery by Liu Jian and Fang-Min. Result of this protocol verification prove that AODV BA could satisfied route discovery property and AODV Reliable Delivery could satisfied packet delivery property within their specification time.   Keywords—Protocol Verification, Timed Automata, AODV, UPPAAL

    Full Text Available Diabetes mellitus (DM is one of the primary causes of premature death and disability worldwide. We performed a systematic review and meta-analysis of the published literature regarding the trends in prevalence, awareness, treatment, and control of diabetes mellitus in mainland China. PUBMED, EMBASE, Chinese Biomedical Database, China National Infrastructure database, Chinese Wan Fang database, and Chongqing VIP database were searched. Fifty-six eligible studies were included. Increasing trends in the prevalence, treatment, and control of diabetes in mainland China from 1979 to 2012 were observed. The pooled prevalence, awareness, treatment, and control of diabetes mellitus were 6.41%, 45.81%, 42.54%, and 20.87%, respectively. A higher prevalence of diabetes mellitus was found in urban (7.48%, 95%CI = 5.45~9.50 than rural (6.53%, 95%CI = 4.30~8.76 areas. Furthermore, an increasing chronological tendency was shown in different subgroups of age with regard to the prevalence of diabetes. A higher awareness of DM was found in urban (44.25%, 95%CI = 32.60~55.90 than rural (34.27%, 95%CI = 21.00~47.54 populations, and no significant differences were found in the treatment, and control of diabetes among the subgroups stratified by gender and location. From 1979 to 2012, the prevalence, treatment, and control of diabetes mellitus increased; nevertheless, there was no obvious improvement in the awareness of diabetes.

    Highlights: • Viscosities of four binary mixtures of [Emim][BF4] with organic solvents. • Viscosity models based on Eyring’s theory. • Excess functions calculated. • Data for binaries new in the literature, except for system with DMSO. - Abstract: This paper reports experimental values of dynamic viscosity for four binary systems of 1-ethyl-3-methylimidazolium tetrafluoroborate, [Emim][BF4], with dimethyl sulfoxide (DMSO), acetonitrile (ACN), ethylene glycol (EG) and 1,4-dioxane over the temperature ranges from 293.15 K to 353.15 K at p = 0.1 MPa. All binary mixtures were completely miscible over the entire range of mole fraction, except the system with 1,4-dioxane. The viscosity results have been correlated by the one parameter Grunberg–Nissan and Fang and He equations and the two-parameter McAllister, Eyring-UNIQUAC, Eyring-NRTL and Eyring-Wilson models and the results were compared. Additionally, the viscosity deviations, Δη, and the excess Gibbs energy of activation for viscous flow, G"∗"E, were calculated and fitted to the Redlich–Kister equation. The results show that all Δη values are negative over the whole composition range and the G"∗"E values are positive, except for the system with EG. The results of the excess functions are discussed in terms of molecular interactions.

  17. Carbon Nanotubes as Counter Electrodes for Gratzel Solar Cells (United States)

    Shodive, Hasan; Aliev, Ali; Zhang, Mei; Lee, Sergey; Baughman, Ray; Zakhidov, Anvar


    The role of interfaces is very critical for solar cell devices which use nanostructured materials. Dye Sensitized Solar Cells (DSSC) are devices which parts are interfacial in character and physico --chemical processes occur at the interface of two distinct media. DSSC are of great interest due to combination of their high efficiency and relatively low cost. An effective counterelectrode with high electrochemical activity is an important component of DSSC to enhance its practical utility. Presently used Pt coated ITO counterelectrode can not be applied in flexible DSSC architectures, while there is a growing need for flexible anodes which are transparent and have desired interface characteristics. In this work in order to search for such materials for counter electrode in dye sensitized solar cells, newly developed strong and transparent and modified carbon nanotube sheets [1] are used in interfacial counter electrode. To increase the electrochemical activity of the anode the CNT sheets are coated with highly conductive SWCNT and compared with pure multiwall CNT sheets. We show that the transparent sheets of SWCNT/MWCNT perform as a flexible anode and as electrochemical catalyst and also can be used in tandems of dye sensitized solar cells as transparent charge recombination or interconnect layers.

  18. Herbart om oppdragelse, formbarhet og takt

    Directory of Open Access Journals (Sweden)

    Lars Løvlie


    Full Text Available Jeg presenterer her en analyse og tolkning av Herbarts syn på oppdragelse og danning, med feste i to av hans begreper: formbarhet – Bildsamkeit – og takt. Det første kaster lys over forholdet mellom lærer og elev, det andre først og fremst over forholdet mellom teori og praksis. For ham, som for forgjengeren Immanuel Kant, dreiet det seg om subjektivitet og frihet, eller mer konkret: Hvordan oppdra til autonomi der det også kreves tvang? Så vidt jeg kan se, bruker Herbart de to grunnbegrepene nettopp til å bestemme det paradoksale og uferdige forholdet mellom frihet og tvang. Han forklarer det som et åpent forhold eller relasjon som ikke har en bestemt begynnelse og heller ikke en bestemt konklusjon. Verken tradisjon eller vitenskap kan ved seg selv realisere dette råderommet. Han tenker seg et frirom der kunnskap, intuisjon og skjønn spiller på lag i oppdragelsen. Tradisjonen henger gjerne igjen i gamle fordommer, vitenskapen fanges i teori og abstrakt skjema, og ingen av dem dekker de unike situasjonene som nyskaper forholdet mellom voksne og barn. Herbart stilte seg åpen til spørsmål som ikke løses ved styring og kontroll, og spør implisitt om ikke vi også kan gjøre det samme.

    Cui, Chuyun; Li, Yufeng; Geng, Dongrong; Zhang, Hui; Jin, Changde


    The aim of this meta-analysis was to assess the effectiveness of evidence-based nursing (EBN) on the development of critical thinking for nursing students. A systematic literature review of original studies on randomized controlled trials was conducted. The relevant randomized controlled trials were retrieved from multiple electronic databases including Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health (CINAHL), Chinese BioMed Database (CBM), China National Knowledge Infrastructure (CNKI), and WanFang Database. In order to make a systematic evaluation, studies were selected according to inclusion and exclusion criteria, and then according to extracted data and assessed quality. The data extraction was completed by two independent reviewers, and the methodological quality assessment was completed by another two reviewers. All of the data was analyzed by the software RevMan5.3. A total of nine studies with 1079 nursing students were chosen in this systematic literature review. The result of this meta-analysis showed that the effectiveness of evidence-based nursing was superior to that of traditional teaching on nursing students' critical thinking. The results of this meta-analysis indicate that evidence-based nursing could help nursing students to promote their development of critical thinking. More researches with higher quality and larger sample size can be analyzed in the further. Copyright © 2018. Published by Elsevier Ltd.

    Full Text Available Kehai Gao, Hongtao Li, Caihong Huang, Huazhuang Li, Jun Fang, Chen Tian Department of Orthopaedics, Yidu Central Hospital, Shandong, People’s Republic of China Introduction: Anaplastic large cell lymphoma (ALCL is a type of non-Hodgkin lymphoma that has strong expression of CD30. ALCL can sometimes involve the bone marrow, and in advanced stages, it can produce destructive extranodal lesions. But anaplastic large cell lymphoma kinase (ALK+ ALCL with soft tissue involvement is very rare.Case report: A 35-year-old woman presented with waist pain for over 1 month. The biopsy of soft tissue lesions showed that these cells were positive for ALK-1, CD30, TIA-1, GranzymeB, CD4, CD8, and Ki67 (90%+ and negative for CD3, CD5, CD20, CD10, cytokeratin (CK, TdT, HMB-45, epithelial membrane antigen (EMA, and pan-CK, which identified ALCL. After six cycles of Hyper-CVAD/MA regimen, she achieved partial remission. Three months later, she died due to disease progression.Conclusion: This case illustrates the unusual presentation of ALCL in soft tissue with a bad response to chemotherapy. Because of the tendency for rapid progression, ALCL in young adults with extranodal lesions are often treated with high-grade chemotherapy, such as Hyper-CVAD/MA. Keywords: anaplastic large cell lymphoma, ALK+, soft tissue involvement, Hyper-CVAD/MA

    Full Text Available Objective To systematically investigate the correlation between the polymorphism of angiotensin converting enzyme (ACE gene I/D and hypertrophic cardiomyopathy. Methods The databases, such as PubMed, Embase, OVID, Web of Science, Cochrane library, CNKI, WanFang Data and VIP, were searched to collect the studies on the correlation between ACE I/D polymorphism and hypertrophic cardiomyopathy susceptibility. Studies that met the inclusion criteria were Meta-analyzed using Stata 11.0 software. Results Fifteen articles were collected including 1114 cases and 1648 controls. The Meta-analysis indicated that there was significant correlation between the 4 models of ACE I/D polymorphism and hypertrophic cardiomyopathy susceptibility [D vs I: OR=1.49, 95%CI (1.20, 1.84; DD vs (ID+II: OR=1.56, 95%CI (1.17, 2.08; (DD+ID vs II: OR=1.76, 95%CI (1.30, 2.38; DD vs II: OR=2.20, 95%CI (1.44, 3.37]. In subgroup analysis, the significant difference existed in Asian population, but no significance was found in European population (P<0.05. Conclusions There is a positive correlation between hypertrophic cardiomyopathy and ACE I/D polymorphism in population, and D allele and DD genotype are likely to be the risk factors of hypertrophic cardiomyopathy. But such correlation does not exist in European population. DOI: 10.11855/j.issn.0577-7402.2013.12.07

  2. On merging Acer sections Rubra and Hyptiocarpa: Molecular and morphological evidence. (United States)

    Harris, A J; Chen, Yousheng; Olsen, Richard T; Lutz, Sue; Wen, Jun


    In this study, we expanded Acer sect. Rubra Pax to include A. sect. Hyptiocarpa Fang. Traditionally, section Rubra comprises two iconic species, Acer rubrum Linnaeus (red maple) and A. saccharinum Linnaeus (silver maple), of eastern North American forests as well as the rare Japanese montane species, A. pycnanthum K. Koch. Section Hyptiocarpa consists of A. laurinum Hasskarl and A. pinnatinervium Merrill, which occur in subtropical and tropical regions of southwestern China to southeast Asia. Here, we confirm prior phylogenetic results showing the close relationship between sects. Rubra and Hyptiocarpa , and we use scanning electron microscopy to demonstrate that leaves of species within these sections have similar arrangements of cuticular waxes, which account for the silvery color of their abaxial surfaces. We describe that the sections also share labile sex expression; inflorescences that range from compound racemose thyrses, to racemes or umbels and that may have undergone evolutionary reduction; and several features of their fruits, such as seed locules without keels, basal portion of wings straight, acute attachment angle between mericarps, and production of some mericarps that are seedless and partially developed at maturity. Our expansion of sect. Rubra to include sect. Hyptiocarpa better elucidates the biogeographic and evolutionary history of these species. Additionally, we show that A. laurinum and A. pinnatinervium have intergrading morphology and are probably synonymous, but we note that further studies are required to conclude their taxonomic status.

    Jie Wang


    Full Text Available Background. To simplify traditional Chinese medicine syndrome differentiation and allow researchers to master syndrome differentiation for hypertension, this paper retrospectively studied the literature and analyzed syndrome elements corresponding to hypertension syndromes. Methods. Six databases including PubMed, EMBASE, Chinese Bio-Medical Literature Database, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan-fang Data were searched from 1/January/2003 to 30/October/2013. We included all clinical literature testing hypertension syndromes and retrospectively studied the hypertension literature published from 2003 to 2013. Descriptive statistics calculated frequencies and percentages. Results. 13,272 patients with essential hypertension were included. Clinical features of hypertension could be attributed to 11 kinds of syndrome factors. Among them, seven syndrome factors were excess, while four syndrome factors were deficient. Syndrome targets were mainly in the liver and related to the kidney and spleen. There were 33 combination syndromes. Frequency of single-factor syndromes was 31.77% and frequency of two-factor syndromes was 62.26%. Conclusions. Excess syndrome factors of hypertension patients include yang hyperactivity, blood stasis, phlegm turbidity, internal dampness, and internal fire. Deficient syndrome factors of hypertension patients are yin deficiency and yang deficiency. Yin deficiency with yang hyperactivity, phlegm-dampness retention, and deficiency of both yin and yang were the three most common syndromes in clinical combination.

This study examined these two factors in the brains of rats following unpredictable chronic mild stress for 4 weeks, with the hypothesis that chronic stress may affect oligodendrocytes and elevate proinflammatory cytokines in the brain. After suffering unpredictable stressors for 4 weeks, the rats showed depression-like behaviors, including decreased locomotion in the open field, increased immobility time in the forced swim test, and decreased sucrose consumption and less sucrose preference when compared with controls. Immunohistochemical staining of brain sections showed higher immunoreactivity of proinflammatory cytokines in certain brain regions of stressed rats compared with controls; lower immunoreactivity of myelin basic protein and fewer mature oligodendrocytes were seen in the prefrontal cortex, but no demyelination was detected. These results are interpreted and discussed in the context of recent findings from human and animal studies. Keywords: cytokines, depression, myelination, oligodendrocytes, stress

    To systemically evaluate the post-marketing safety of Guizhi Fuling Jiaonang. Computer retrieval was conducted in Medline, EMbase, the Web of Science, Clinical Trials. Gov, the Cochrane Library, CNKI, VIP, WanFang Data and CBM to collect relevant information. The papers were then screened according to inclusion and exclusion criteria. A total of 234 papers were included in this study, including 164 randomized controlled trials, 7 quasi-randomized controlled trials, 8 non-randomized controls, 56 case series, and 1 cohort study. The patients were only treated with Guizhi Fuling Jiaonang in 56 studies, and Guizhi Fuling Jiaonang was combined with other drugs in 178 studies. The total ADRs/AEs incidence was 1.99% in single use of Guizhi Fuling Jiaonang, and 8.21% in combined use, but showing no severe adverse reactions. Gastrointestinal system damage was most common in mild ADRs. In this study, it was found that the overall safety of Guizhi Fuling Jiaonang was acceptable. The direct evidences of the drug's safety case reports were systematically analyzed in this study, but the mechanism study on the safety of the drug after marketing or the prospective long-term clinical observation study was not sufficient, so the further studies on the safety of drug use should be conducted in order to provide better guidance for clinical medication.

    To evaluate the association between the SPO11 gene C631T polymorphism and the risk of male infertility. We conducted a search on PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China biology medical literature database (CBM), VIP, and Chinese literature database (Wan Fang) on 31 March 2016. Odds ratio (OR) and 95% confidence interval (95%CI) were used to assess the strength of associations. A total of five studies including 542 cases and 510 controls were involved in this meta-analysis. The pooled results indicated that the SPO11 gene C631T polymorphism was significantly associated with increased risk of male infertility (TT + CT vs. CC: OR = 4.14, 95%CI = 2.48-6.89; CT vs. CC: OR = 4.34, 95%CI = 2.56-7.34; T vs. C: OR = 4.35, 95%CI = 2.58-7.34). Subgroup analysis of different countries proved the relationship between SPO11 gene C631T polymorphism and male infertility risk in Chinese, but not in Iranian peoples. In conclusion, this study suggested that SPO11 gene C631T polymorphism may contribute as a genetic factor susceptible to cause male infertility. Furthermore, more large sample and representative population-based cases and well-matched controls are needed to validate our results.

Databases including CNKI, VIP, WanFang, SinoMed, PubMed, Cochrane Library, and database were retrieved for relevant literature, with the retrieval deadline being November 2017. Two reviewers independently screened, selected, and extracted data and validated the results. The methodological quality was evaluated with the “Risk of Bias” tool, and the meta-analysis was performed by using the RevMan 5.3.5 software. Results. Totally 953 patients with postpartum urinary retention from 15 randomized controlled trials entered the meta-analysis. 12 articles compared the clinical cure rate of acupuncture alone versus intramuscular injection of neostigmine and found the cure rate in the acupuncture group was 2 times that in the neostigmine group (RR, 1.91; 95% CI: 1.66–2.19. 15 articles compared the clinical effectiveness rate of acupuncture alone with that of intramuscular injection of neostigmine and found the clinical effectiveness rate was 28% higher in the acupuncture group than in the neostigmine group (RR: 1.28; 95% CI: 1.16–1.42. No adverse event was reported in the acupuncture group. Conclusion. Acupuncture alone is more effective in treating postpartum urinary retention than intramuscular injection of neostigmine, with good safety profile. Therefore, it is a feasible and valuable technique in clinical settings.

    Femtosecond lasers have a unique ability of processing bulk transparent materials for various applications such as micromachining, waveguide manufacturing, and photonic bandgap structures just to name a few. These applications depend on the formation of micron or submicron size features that are known to be index modifications to the bulk substrate [H. Guo, H. Jiang, Y. Fang, C. Peng, H. Yang, Y. Li, Q. Gong, J. Opt. A: Pure Appl. Opt. 6 (2004) 787]. To the best of our knowledge the physical understanding of how these index-modified features are formed is still unknown, but many good theories exist such as Petite et al. [G. Petite, P. Daguzan, S. Guizard, P. Martin, in: IEEE Annual Report Conference on Electrical Insulation and Dielectric Phenomena, vol. 15, IEEE, 1995, pp. 40-44] or Tien et al. [A. Tien, S. Backus, H. Kapteyn, M. Murnane, G. Mourou, Phys. Rev. Lett. 82 (1999) 3883]. In this Letter the question on the physical cause for index changes is investigated by the combined efforts between Wright-Patterson AFB (WPAFB) and the University of Dayton (UD) using numerous imaging equipment such as TEM, AFM, NSOM, Nomarski microscopy, X-ray crystallography, Raman spectroscopy, and even diffraction efficiency experiments. With all the combined imaging equipment this research is able to present valuable data and deduce plausible theories of the physics of the index modification mechanism

  9. The role of autophagy in microbial infection and immunity

    Desai M


    Full Text Available Mayura Desai,1 Rong Fang,2 Jiaren Sun11Department of Microbiology and Immunology, 2Department of Pathology, University of Texas Medical Branch at Galveston, Galveston, TX, USAAbstract: The autophagy pathway represents an evolutionarily conserved cell recycling process that is activated in response to nutrient deprivation and other stress signals. Over the years, it has been linked to an array of cellular functions. Equally, a wide range of cell-intrinsic, as well as extracellular, factors have been implicated in the induction of the autophagy pathway. Microbial infections represent one such factor that can not only activate autophagy through specific mechanisms but also manipulate the response to the invading microbe's advantage. Moreover, in many cases, particularly among viruses, the pathway has been shown to be intricately involved in the replication cycle of the pathogen. Conversely, autophagy also plays a role in combating the infection process, both through direct destruction of the pathogen and as one of the key mediating factors in the host defense mechanisms of innate and adaptive immunity. Further, the pathway also plays a role in controlling the pathogenesis of infectious diseases by regulating inflammation. In this review, we discuss various interactions between pathogens and the cellular autophagic response and summarize the immunological functions of the autophagy pathway.Keywords: autophagy, xenophagy, antiviral, antibacterial

    Ewing's sarcoma is a devastating rare pediatric cancer of the bone. Intense chemotherapy temporarily controls disease in most patients at presentation but has limited effect in patients with progressive or recurrent disease. We previously described preliminary results of a novel immunotherapy, FANG (Vigil) vaccine, in which 12 advanced stage Ewing's patients were safely treated and went on to achieve a predicted immune response (IFNγ ELISPOT). We describe follow-up through year 3 of a prospective, nonrandomized study comparing an expanded group of Vigil-treated advanced disease Ewing's sarcoma patients (n = 16) with a contemporaneous group of Ewing's sarcoma patients (n = 14) not treated with Vigil. Long-term follow-up results show a survival benefit without evidence of significant toxicity (no ≥ grade 3) to Vigil when administered once monthly by intradermal injection (1 × 10e(6) cells/injection to 1 × 10e(7) cells/injection). Specifically, we report a 1-year actual survival of 73% for Vigil-treated patients compared to 23% in those not treated with Vigil. In addition, there was a 17.2-month difference in overall survival (OS; Kaplan-Meier) between the Vigil (median OS 731 days) and no Vigil patient groups (median OS 207 days). In conclusion, these results supply the rational for further testing of Vigil in advanced stage Ewing's sarcoma.

    By employing angle-resolved photoemission spectroscopy combined with first-principles calculations, we performed a systematic investigation on the electronic structure of LaBi, which exhibits extremely large magnetoresistance (XMR), and is theoretically predicted to possess band anticrossing with nontrivial topological properties. Here, the observations of the Fermi-surface topology and band dispersions are similar to previous studies on LaSb [L.-K. Zeng, R. Lou, D.-S. Wu, Q. N. Xu, P.-J. Guo, L.-Y. Kong, Y.-G. Zhong, J.-Z.

Lett. 117, 127204 (2016), 10.1103/PhysRevLett.117.127204], a topologically trivial XMR semimetal, except the existence of a band inversion along the Γ -X direction, with one massless and one gapped Dirac-like surface state at the X and Γ points, respectively. The odd number of massless Dirac cones suggests that LaBi is analogous to the time-reversal Z2 nontrivial topological insulator. These findings open up a new series for exploring novel topological states and investigating their evolution from the perspective of topological phase transition within the family of rare-earth monopnictides.

Currently, this medicinal mushroom is also used as a dietary supplement in numerous Western and Eastern countries. Armillarikin was isolated from A. mellea, and we previously discovered that it induced cytotoxicity in human leukemia cells. In this study, we further investigated the cytotoxicity of armillarikin against liver and intrahepatic bile duct cancer cells. Armillarikin was cytotoxic against human hepatocellular carcinoma Huh7, HA22T, and HepG2 cells based on the 3-(4,5-dimethylthiazol-2-yl-5-(3-carboxymethoxyphenyl-2-(4-sulfophenyl-2H-tetrazolium and alamarBlue® assays. Armillarikin treatment also induced the collapse of the mitochondrial transmembrane potential of these cells. Furthermore, armillarikin-induced apoptotic cell death was demonstrated by sub-G1 chromosomal DNA formation by using flow cytometry. In addition, the apoptosis was inhibited by the pan-caspase inhibitor, Z-VAD-fmk. Immunoblotting also revealed the armillarikin-induced activation of procaspase-3, -8, and -9 and upregulation of the apoptosis- and cell cycle arrest-related phospho-histones 2 and 3, respectively. Moreover, reactive oxygen species scavengers also inhibited the armillarikin-induced apoptosis in human hepatocellular carcinoma, suggesting that reactive oxygen species formation played an important role in the armillarikin-induced apoptosis of human hepatocellular carcinoma.

Methods: A prospective, randomized, double-blinded study compared the effects of an antioxidant supplement (containing anthocyanosides, astaxanthin, vitamins A, C, and E, and several herbal extracts, including Cassiae semen and Ophiopogonis japonicus with placebo on patients with DES. We assessed dry eye symptoms, visual acuity, Schirmer’s test, tear film breakup time, cornea and conjunctiva fluorescein staining, serum anti-SSA/anti-SSB antibodies, and the level of reactive oxygen species (ROS in tears. The supplementation period was 8 weeks and patients were followed up every 4 weeks for 16 weeks. A linear mixed model was used to compare the groups, while within-group differences were tested by repeated-measures analysis of variance. Results: Forty-three patients, 20 and 23 in treatment and placebo groups, respectively, completed the study. Liver and renal functions were normal. Diastolic blood pressure decreased in the treatment group. There were no significant differences in systolic blood pressure, dry eye symptoms, serum anti-SSA and anti-SSB, visual acuity, intraocular pressure, or fluorescein corneal staining between the groups. Tear film breakup time scores and Schirmer’s test without topical anesthesia significantly improved in the treatment group. Tear ROS level differed between the groups and decreased after treatment. Overall subjective impression revealed a significant improvement with treatment compared with placebo. Conclusion: Oral antioxidant supplementations may increase tear production and improve tear film stability by reducing tear ROS. The vegetable-based antioxidant supplement used in this study is safe and can be utilized as

  17. Found: A Galaxy's Missing Gamma Rays (United States)

    Kohler, Susanna


    Recent reanalysis of data from the Fermi Gamma-ray Space Telescope has resulted in the first detection of high-energy gamma rays emitted from a nearby galaxy. This discovery reveals more about how supernovae interact with their environments.Colliding Supernova RemnantAfter a stellar explosion, the supernovas ejecta expand, eventually encountering the ambient interstellar medium. According to models, this generates a strong shock, and a fraction of the kinetic energy of the ejecta is transferred into cosmic rays high-energy radiation composed primarily of protons and atomic nuclei. Much is still unknown about this process, however. One open question is: what fraction of the supernovas explosion power goes into accelerating these cosmic rays?In theory, one way to answer this is by looking for gamma rays. In a starburst galaxy, the collision of the supernova-accelerated cosmic rays with the dense interstellar medium is predicted to produce high-energy gamma rays. That radiation should then escape the galaxy and be visible to us.Pass 8 to the RescueObservational tests of this model, however, have beenstumped by Arp 220. This nearby ultraluminous infrared galaxy is the product of a galaxy merger ~700 million years ago that fueled a frenzy of starbirth. Due to its dusty interior and extreme levels of star formation, Arp 220 has long been predicted to emit the gamma rays produced by supernova-accelerated cosmic rays. But though weve looked, gamma-ray emission has never been detected from this galaxy until now.In a recent study, a team of scientists led by Fang-Kun Peng (Nanjing University) reprocessed 7.5 years of Fermi observations using the new Pass 8 analysis software. The resulting increase in resolution revealed the first detection of GeV emission from Arp 220!Acceleration EfficiencyGamma-ray luminosity vs. total infrared luminosity for LAT-detected star-forming galaxies and Seyferts.

    Full Text Available Gangqiang Ding, Zhen Peng, Jia Shang, Yi Kang, Huibin Ning, Chongshan Mao Department of Infectious Diseases, People’s Hospital of Zhengzhou University, Henan Provincial People’s Hospital, Zhengzhou, China Abstract: In the previous study, it was found that long intergenic noncoding RNA-p21 (lincRNA-p21 was downregulated in hepatocellular carcinoma (HCC and lincRNA-p21 overexpression inhibited tumor invasion through inducing epithelial–mesenchymal transition. However, the underlying mechanism was not fully elaborated. In this study, lincRNA-p21 expression was measured in 12 paired HCC and nontumor adjacent normal tissues by ­quantitative real-time polymerase chain reaction. The effects of lincRNA-p21 on HCC cells were studied using lentivirus expressing lincRNA-p21 vector in vitro. The association between lincRNA-p21 level and miR-9 level was tested with the Spearman rank correlation. The effects of miR-9 on HCC cells were studied by using miR-9 inhibitor in vitro. Luciferase assay was used to validate the target of miR-9. The results showed that lincRNA-p21 was downregulated in human HCC tissues and cell lines. LincRNA-p21 overexpression significantly inhibited HCC cell migration and invasion in vitro. Besides, lincRNA-p21 negatively regulated miR-9 expression level, and miR-9 was upregulated in human HCC tissues and cells. MiR-9 knockdown inhibited HCC cell migration and invasion in vitro. Finally, the luciferase assay results showed that E-cadherin was a direct target of miR-9. The expression level of E-cadherin was found to be regulated by lincRNA-p21 and miR-9. Altogether, the results suggested that lincRNA-p21 inhibits migration and invasion of HCC cells through regulating miR-9-mediated E-cadherin cascade signaling pathway.

  19. Issues in measure-preserving three dimensional flow integrators: Self-adjointness, reversibility, and non-uniform time stepping

    International Nuclear Information System (INIS)

    Finn, John M.


    Properties of integration schemes for solenoidal fields in three dimensions are studied, with a focus on integrating magnetic field lines in a plasma using adaptive time stepping. It is shown that implicit midpoint (IM) and a scheme we call three-dimensional leapfrog (LF) can do a good job (in the sense of preserving KAM tori) of integrating fields that are reversible, or (for LF) have a “special divergence-free” (SDF) property. We review the notion of a self-adjoint scheme, showing that such schemes are at least second order accurate and can always be formed by composing an arbitrary scheme with its adjoint. We also review the concept of reversibility, showing that a reversible but not exactly volume-preserving scheme can lead to a fractal invariant measure in a chaotic region, although this property may not often be observable. We also show numerical results indicating that the IM and LF schemes can fail to preserve KAM tori when the reversibility property (and the SDF property for LF) of the field is broken. We discuss extensions to measure preserving flows, the integration of magnetic field lines in a plasma and the integration of rays for several plasma waves. The main new result of this paper relates to non-uniform time stepping for volume-preserving flows. We investigate two potential schemes, both based on the general method of Feng and Shang [Numer. Math. 71, 451 (1995)], in which the flow is integrated in split time steps, each Hamiltonian in two dimensions. The first scheme is an extension of the method of extended phase space, a well-proven method of symplectic integration with non-uniform time steps. This method is found not to work, and an explanation is given. The second method investigated is a method based on transformation to canonical variables for the two split-step Hamiltonian systems. This method, which is related to the method of non-canonical generating functions of Richardson and Finn [Plasma Phys. Controlled Fusion 54, 014004 (2012

    The reconstruction of the historical forest spatial distribution is of a great significance to understanding land surface cover in historical periods as well as its climate and ecological effects. Based on the maximum scope of historical forest land before human intervention, the characteristics of human behaviors in farmland reclamation and deforestation for heating and timber, we create a spatial evolution model to reconstruct the spatial pattern of historical forest land. The model integrates the land suitability for reclamation, the difficulty of deforestation, the attractiveness of timber trading markets and the abundance of forest resources to calibrate the potential scope of historical forest land with the rationale that the higher the probability of deforestation for reclamation and wood, the greater the likelihood that the forest land will be deforested. Compared to the satellite-based forest land distribution in 2000, about 78.5% of our reconstructed historical forest grids are of the absolute error between 25% and -25% while as many as 95.85% of those grids are of the absolute error between 50% and -50%, which indirectly validates the feasibility of our reconstructed model. Then, we simulate the spatial distribution of forest land in China in 1661, 1724, 1820, 1887, 1933 and 1952 with the grid resolution of 1 km × 1 km. Our result shows that (1) the reconstructed historical forest land in China in the past 300 years concentrates in DaXingAnLing, XiaoXingAnLing, ChangBaiShan, HengDuanShan, DaBaShan, WuYiShan, DaBieShan, XueFengShang and etc.; (2) in terms of the spatial evolution, historical forest land shrank gradually in LiaoHe plains, SongHuaJiang-NenJiang plains and SanJiang plains of eastnorth of China, Sichuan basins and YunNan-GuiZhou Plateaus; and (3) these observations are consistent to the proceeding of agriculture reclamation in China in past 300 years towards Northeast China and Southwest China.

Phospholipids (PLs play an essential role in memory and learning abilities. Moreover, PLs act as a source of choline in acetylcholine synthesis. This study aimed to prepare and optimize the formulation of chitosan/phospholipid/β-cyclodextrin (CTS/PL/β-CD microspheres that can improve cognitive impairment. The CTS/PL/β-CD microspheres were prepared by spray drying, and optimized with an orthogonal design. These microspheres were also characterized in terms of morphology, structure, thermostability, drug loading, and encapsulation efficiency. The spatial learning and memory of rats were evaluated using the Morris water maze test, and the neuroprotective effects of the CTS/PL/β-CD microspheres were investigated by immunohistochemistry. Scanning electron microscopic images showed that the CTS/PL/β-CD microspheres were spherical with slightly wrinkled surfaces. Fourier transform infrared spectroscopy and differential scanning calorimetry proved that PLs formed hydrogen bonds with the amide group of CTS and the hydroxyl group of β-CD. The learning and memory abilities of rats in the treated group significantly improved compared with those in the model group. Immunohistochemical analysis revealed that treatment with the CTS/PL/β-CD microspheres attenuated the expression of protein kinase C-δ and inhibited the activation of microglias. These results suggest that the

    Full Text Available John Y Fang, Christopher Tolleson Department of Neurology, Vanderbilt University Medical Center, Nashville, TN, USA Abstract: Parkinson’s disease (PD is a progressive neurodegenerative disorder characterized by the loss of neuronal dopamine production in the brain. Oral therapies primarily augment the dopaminergic pathway. As the disease progresses, more continuous delivery of therapy is commonly needed. Deep brain stimulation (DBS has become an effective therapy option for several different neurologic and psychiatric conditions, including PD. It currently has US Food and Drug Administration approval for PD and essential tremor, as well as a humanitarian device exception for dystonia and obsessive-compulsive disorder. For PD treatment, it is currently approved specifically for those patients suffering from complications of pharmacotherapy, including motor fluctuations or dyskinesias, and a disease process of at least 4 years of duration. Studies have demonstrated superiority of DBS and medical management compared to medical management alone in selected PD patients. Optimal patient selection criteria, choice of target, and programming methods for PD and the other indications for DBS are important topics that continue to be explored and remain works in progress. In addition, new hardware options, such as different types of leads, and different software options have recently become available, increasing the potential for greater efficacy and/or reduced side effects. This review gives an overview of therapeutic management in PD, specifically highlighting DBS and some of the recent changes with surgical therapy.

Meta-analyses demonstrated that both JYT (RR 1.41; 95% CI 1.27, 1.57; P < 0.00001 and JYT + western medicine (RR 1.27; 95% CI 1.17, 1.38; P < 0.00001 were more efficacious than only western medicine. Furthermore, JYT had potential improvement on traditional Chinese medicine (TCM symptoms scores such as stomachache, stomach distention, belching, fatigue, et al. In addition, no serious adverse events were reported in the selected trials. The Cochrane Collaboration's risk of bias tool was evaluated for the weaknesses of methodological quality, while the quality level of Grades of Recommendations Assessment Development and Evaluation (GRADE evidence classification indicated "Very low". This meta-analysis indicates that JYT may have potential effects on the treatment of patients with CAG. However, due to limitations of methodological quality and small sample size of the included studies, further standardized research of rigorous design should be needed.

    The most preferable vascular access for patients with end-stage renal failure needing hemodialysis is native arteriovenous fistula (AVF) on account of its access longevity, patient morbidity, hospitalization costs, lower risks of infection and fewer incidence of thrombotic complications. Meanwhile, according to National Kidney Foundation (NKF)̸Dialysis Out-comes Quality Initiative (DOQI) guidelines, AVF is more used than before. However, a significant percentage of AVF fails to support dialysis therapy due to lack of adequate maturity. Among all factors, the presence of diabetes mellitus was shown to be one of the risk factors for the development of vascular access failure by some authors. Therefore, this review evaluates the current evidence concerning the correlation of diabetes and AVF failure. A search was conducted using MEDLINE, SCIENCE DIRECT, SPRINGER, WILEY-BLACKWELL, KARGER, EMbase, CNKI and WanFang Data from the establishment time of databases to January 2016. The analysis involved studies that contained subgroups of diabetic patients and compared their outcomes with those of non-diabetic adults. In total, 23 articles were retrieved and included in the review. The meta-analysis revealed a statistically significantly higher rate of AVF failure in diabetic patients compared with non-diabetic patients (OR = 1.682; 95% CI, 1.429-1.981, Test of OR = 1: z = 6.25, p <.001). This review found an increased risk of AVF failure in diabetes patients. If confirmed by further prospective studies, preventive measure should be considered when planning AVF in diabetic patients.

    The aim of the present study was to estimate the impact of dehydroepiandrosterone sulfate (DHEAS) on the prognosis of patients with cardiovascular disease by performing a systematic review and meta-analysis. The Embase, PubMed, Web of Science, CNKI, and WanFang databases were searched up to September 5, 2016, to identify eligible studies. The quality of each study was assessed using the Newcastle-Ottawa Scale. The association between DHEAS, either on admission or at discharge, and cardiovascular disease outcomes were reviewed. The overall risk ratio for the effect of DHEAS on all-cause mortality and fatal and nonfatal cardiovascular events was pooled using a fixed-effects or a random-effects model. The publication bias was evaluated using funnel plots. Twenty-five studies were included for systematic review. The follow-up duration ranged from 1 to 19 years. Eighteen studies were included in the meta-analysis. We found that lower DHEAS levels indicated a significant increased risk for all-cause mortality (risk ratio, 1.47; 95% CI, 1.38-1.56 [ P <0.00001]), fatal cardiovascular event (risk ratio, 1.58; 95% CI, 1.30-1.91 [ P <0.00001]), and nonfatal cardiovascular event (risk ratio, 1.42; 95% CI, 1.24-1.62 [ P <0.0001]) in patients with cardiovascular disease. Patients with cardiovascular disease who have lower DHEAS levels may have poorer prognosis than those with higher DHEAS levels. © 2017 The Authors.

  6. S1P transporter SPNS2 regulates proper postnatal retinal morphogenesis. (United States)

    Spinster homolog 2 (SPNS2) is the membrane transporter of sphingosine-1-phosphate (S1P), and it participates in several physiologic processes by activating different S1P receptors (S1PRs). However, its functions in the nervous system remain largely unclear. We explored the important role of SPNS2 in the process of retinal morphogenesis using a spns2-deficient rat model. In the absence of the functional SPNS2 transporter, we observed progressively aggravating laminar disorganization of the epithelium at the postnatal stage of retinal development. Disrupted cell polarity, delayed cell-cycle exit of retinal progenitor cells, and insufficient migration of newborn neurons were proposed in this study as potential mechanisms accounting for this structural disorder. In addition, we analyzed the expression profiles of spns2 and s1prs, and proposed that SPNS2 regulated retinal morphogenesis by establishing the S1P level in the eye and activating S1PR3 signaling.

    Full Text Available BACKGROUND: Two polymorphisms, -260C/T and -651C/T, in the CD14 gene have been implicated in susceptibility to cancer. However, the results remain inconclusive. This meta-analysis aimed to investigate the association between the two polymorphisms and risk of cancer. METHODS: All eligible case-control studies published up to March 2014 were identified by searching PubMed, Web of Science, CNKI and WanFang database. Pooled odds ratio (OR with 95% confidence interval (CI were used to access the strength of this association in fixed- or random-effects model. RESULTS: 17 case-control studies from fourteen articles were included. Of those, there were 17 studies (4198 cases and 4194 controls for -260C/T polymorphism and three studies (832 cases and 1190 controls for -651C/T polymorphism. Overall, no significant associations between the two polymorphisms of CD14 gene and cancer risk were found. When stratified by ethnicity, cancer type and source of control, similar results were observed among them. In addition, in further subgroups analysis by Helicobacter pylori (H. pylori infection status and tumor location in gastric cancer subgroup, we found that the CD14 -260C/T polymorphism may increase the risk of gastric cancer in H. pylori-infected individuals. CONCLUSIONS: This meta-analysis suggests that the CD14 -260C/T polymorphism may increase the risk of gastric cancer in H. pylori-infected individuals. However, large and well-designed studies are warranted to validate our findings.

Here, we report the case of an 83-year-old woman who was prescribed quetiapine (50 mg per day for delirium. Unexpected, global aphasia occurred 3 days after treatment began. Complete recovery occurred following discontinuation of the drug. A brain computed tomography scan excluded intracranial hemorrhage and the laboratory results confirmed that no exacerbation of infection or electrolyte imbalances were present. During the aphasic episode, the patient’s condition did not deteriorate and no new neurological symptoms occurred. We suspect that the occurrence of aphasia was directly due to an adverse reaction to quetiapine. To our knowledge, this is the first case report of reversible, global aphasia as a side effect of quetiapine. We propose that this occurrence of aphasia may be due to the action of quetiapine as a dopamine receptor antagonist. Clinicians should use quetiapine with caution, especially in elderly patients. On observation of aphasia, a review of the patient’s medical history is required to assess for the usage of quetiapine. Keywords: aphasia, quetiapine, insomnia, delirium

    Full Text Available Background and objective The efficacy and safety of radiosensitivity on non-small cell lung cancer (NSCLC using metronidazole amino acidum natrium (CMNa are yet to be proven. This study evaluates the efficacy and safety of radiosensitivity on NSCLC by CMNa to provide references for further clinical practice and research. Methods Relevant randomized controlled trials (RCTs were obtained from the Cochrane library, Pubmed, EMbase, CBM, CNKI, VIP, and Wan Fang databases. Dates were searched through other means. RCTs of radiosensitivity on NSCLC by CMNa were included. The data included in the study were evaluated and analyzed using the Cochrane Collaboration's RevMan 5.1 software. Results A total of 21 RCTs were included. The results of the meta-analyses showed that the total effective rate of the test group that received CMNa plus radiotherapy was higher than that of the control group that received radiotherapy alone (OR=3.29, 95%CI: 2.47-4.39, P<0.000,01 or radiotherapy plus placebo (OR=3.65, 95%CI: 2.25-5.92, P<0.000,01, respectively. No significant differences were found in the quality of life between one and two-year survival rates (P>0.05. No significant differences were found among radiation pneumonitis, radiation esophagitis, hematological toxicity, and cardiotoxicity (P>0.05. Conclusion CMNa plus radiotherapy elicit beneficial effects in the treatment of NSCLC and produce fewer adverse effects. Therefore, this technique can be recommended and applied in clinics.

In this study, we synthesized several cationic copolymers using atom transfer radical polymerization (ATRP for gene delivery vectors: pluronic F127-poly(dimethylaminoethyl methacrylate (PF127-pDMAEMA, pluronic F127-poly (dimethylaminoethyl methacrylate-tert-butyl acrylate (PF127-p(DMAEMA-tBA, and pluronic F127-poly(dimethylaminoethyl methacrylate-acrylic acid (PF127-p(DMAEMA-AA. The copolymers showed high buffering capacity and efficiently complexed with plasmid deoxyribonucleic acid (pDNA to form nanoparticles 80–180 nm in diameter and with positive zeta potentials. In the absence of 10% fetal bovine serum, PF127-p(DMAEMA-AA showed the highest gene expression and the lowest cytotoxicity in 293T cells. After acrylic acid groups had been linked with a fluorescent dye, the confocal laser scanning microscopic image showed that PF127-p(DMAEMA-AA/pDNA could efficiently enter the cells. Both clathrin-mediated and caveolae-mediated endocytosis mechanisms were involved. Our results showed that PF127-p(DMAEMA-AA has great potential to be a gene delivery vector.Keywords: nonviral vector, pluronic F127, dimethylaminoethyl methacrylate, copolymer, atom transfer radical polymerization

    Full Text Available Meng Su,1 Baoli Qin,1 Fang Liu,2 Yuze Chen,2 Rui Zhang2 1Department of Internal Medicine, 2Department of Colorectal Surgery, Cancer Hospital of China Medical University, Liaoning Cancer Hospital and Institute, Liaoning, China Abstract: Colorectal cancer (CRC is the third most common malignant neoplasm worldwide. 5-Fluorouracil (5-Fu is the most important chemotherapeutic drug used for the treatment of CRC. However, resistance to 5-Fu therapies is a growing concern in CRC clinical practice recently. Andrographolide (Andro is a main bioactive constituent of the herb Andrographis paniculata, which has various biological effects including anti-inflammation and antitumor activities. In the present study, we investigated the effects of combined Andro with 5-Fu against CRC HCT-116 cells. In vitro studies showed that Andro synergistically enhanced the anti-proliferation effect of 5-Fu on HCT-116 cells due to increased apoptotic cells. Meanwhile, results of the enzyme linked immunosorbent assay indicated that the level of phosphorylated cellular-mesenchymal to epithelial transition factor (p-MET was decreased by the combination treatment. Further study suggested that Andro promoted the antitumor effect of 5-Fu by downregulating the level of p-MET. In conclusion, these results confirmed the synergistic antitumor activity of Andro on CRC and provide evidence for possible clinical application of Andro for enhancing the antitumor effect of 5-Fu in CRC treatment.

  14. Revolutionary Science. (United States)

    Casadevall, Arturo; Fang, Ferric C


    On rare occasions in the history of science, remarkable discoveries transform human society and forever alter mankind's view of the world. Examples of such discoveries include the heliocentric theory, Newtonian physics, the germ theory of disease, quantum theory, plate tectonics and the discovery that DNA carries genetic information. The science philosopher Thomas Kuhn famously described science as long periods of normality punctuated by times of crisis, when anomalous observations culminate in revolutionary changes that replace one paradigm with another. This essay examines several transformative discoveries in the light of Kuhn's formulation. We find that each scientific revolution is unique, with disparate origins that may include puzzle solving, serendipity, inspiration, or a convergence of disparate observations. The causes of revolutionary science are varied and lack an obvious common structure. Moreover, it can be difficult to draw a clear distinction between so-called normal and revolutionary science. Revolutionary discoveries often emerge from basic science and are critically dependent on nonrevolutionary research. Revolutionary discoveries may be conceptual or technological in nature, lead to the creation of new fields, and have a lasting impact on many fields in addition to the field from which they emerge. In contrast to political revolutions, scientific revolutions do not necessarily require the destruction of the previous order. For humanity to continue to benefit from revolutionary discoveries, a broad palette of scientific inquiry with a particular emphasis on basic science should be supported.

  15. Comprehensive treatment of generalized parodontitis. (United States)

    Mdinaradze, N


    The complexity of pathogenesis of periodontitis makes the use of comprehensive treatment necessary. We observed 60 patients, 20 women and 40 men among them aged from 20 to 50. In the course of parodontitis, we determined the intensity of inflammatory-destructive changes (Pi) in the course of periodontitis, the degree of fang denudation, the depth of gum and parodontal recesses, degree of the teeth becoming loose; we conducted the microbiological study of the oral cavity microflora and drew up an antibiotic graph. We included laser therapy in the comprehensive treatment course of generalized parodontitis. We divided the patients into two groups. The patients of the first group were treated in two stages. We used peridex, composed of chlorhexidine for antiseptic treatment of oral cavity. We used a combined solution of sage, eucalyptus, camomile and calendula to irrigate the oral cavity. At the second stage we used ointment applications with the composition of 3% indometacin, heparin, vitamins, sea-buckthorn oil and antibiotics. In the course of comprehensive treatment of the patients of the II group we included laser therapy. Our interest in the laser beam, as in the means of parodontitis treatment was stimulated by a number of properties of the laser beam and namely, its anti-inflammatory, desensitizing and antibacterial action promotes intensifying the reparation processes and does not entail any complications. The mentioned method has produced the best therapeutic results and has resulted in the reduced treatment period.

  17. Climate Change Impacts on the Potential Distribution of Eogystia hippophaecolus in China. (United States)

    Li, Xue; Ge, Xuezhen; Chen, Linghong; Zhang, Linjing; Wang, Tao; Shixiang, Zong


    Seabuckthorn carpenter moth, Eogystia hippophaecolus (Hua, Chou, Fang, & Chen, 1990), is the most important boring pest of sea buckthorn (Hippophae rhamnoides L.) in the northwest of China. It is responsible for the death of large areas of H. rhamnoides forest, seriously affecting the ecological environment and economic development in northwestern China. To clarify the potential distribution of E. hippophaecolus in China, the present study used the CLIMEX 4.0.0 model to project the potential distribution of the pest using historical climate data (1981-2010) and simulated future climate data (2011-2100) for China. Under historical climate condition, E. hippophaecolus would be found to be distributed mainly between 27° N - 51° N and 74° E - 134° E, with favorable and highly favorable habitats accounting for 35.2% of the total potential distribution. Under future climate conditions, E. hippophaecolus would be distributed mainly between 27° N - 53° N and 74° E - 134° E, with the possibility of moving in a northwest direction. Under these conditions, the proportion of the total area providing a favorable and highly favorable habitat may decrease to about 33%. These results will help to identify the impact of climate change on the potential distribution of E. hippophaecolus, thereby providing a theoretical basis for monitoring and early forecasting of pest outbreaks.

    Full Text Available Patrick P Kneeland, Margaret C FangThe University of California, San Francisco Division of Hospital Medicine, San Francisco, CA, USAAbstract: Warfarin therapy reduces morbidity and mortality related to thromboembolism. Yet adherence to long-term warfarin therapy remains challenging due to the risks of anticoagulantassociated complications and the burden of monitoring. The aim of this paper is to review determinants of adherence and persistence on long-term anticoagulant therapy for atrial fibrillation and venous thromboembolism. We evaluate what the current literature reveals about the impact of warfarin on quality of life, examine warfarin trial data for patterns of adherence, and summarize known risk factors for warfarin discontinuation. Studies suggest only modest adverse effects of warfarin on quality of life, but highlight the variability of individual lifestyle experiences of patients on warfarin. Interestingly, clinical trials comparing anticoagulant adherence to alternatives (such as aspirin show that discontinuation rates on warfarin are not consistently higher than in control arms. Observational studies link a number of risk factors to warfarin non-adherence including younger age, male sex, lower stroke risk, poor cognitive function, poverty, and higher educational attainment. In addition to differentiating the relative impact of warfarin-associated complications (such as bleeding versus the lifestyle burdens of warfarin monitoring on adherence, future investigation should focus on optimizing patient education and enhancing models of physician–patient shared-decision making around anticoagulation.Keywords: anticoagulation, warfarin, adherence, persistence, thromboembolism

    Full Text Available A retrospective survey of 473 cases of snake bite admitted to a Brazilian teaching hospital from 1984 to 1990 revealed 91 cases of bite without envenoming and/or caused by non-venomous snakes. In 17 of these cases the snake was identified, and one patient was bitten by a snake-like reptile (Amphisbaena mertensii. In 43 cases diagnosis was made on clinical grounds (fang marks in the absence of signs of envenoming. The other 30 cases were of patients who complained of being bitten but who did not show any sign of envenoming or fang mark. Most cases occurred in men (66;73%, in the 10-19 years age group (26;29%, in the lower limbs (51/74;69%, between 6 A. M. and 2 P.M. (49;61% and in the month of April (16; 18%. One patient bitten by Philodryas olfersii developed severe local pain, swelling and redness at the site of the bite, with normal clotting time. The patient bitten by Drymarcon corais was misdiagnosed as being bitten by a snake of the genus Bothrops, was given the specific antivenom, and developed anaphylaxis. One patient bitten by Sibynomorphus mikanii presented prolonged clotting time, and was also given antivenom as a case of Bothrops bite. Correct identification of venomous snakes by physicians is necessary to provide correct treatment to victims of snake bite, avoiding unnecessary distress to the patient, and overprescription of antivenom, which may eventually cause severe untoward effects.Um levantamento retrospectivo de 473 casos de acidentes ofídicos admitidos em um hospital-escola brasileiro de 1984 a 1990 revelou 91 casos sem envenenamento e/ou causados por serpentes não-peçonhentas.

Though carbapenems are frequently prescribed for CE infections, the emergence of carbapenem-resistant Enterobacteriaceae is of huge concern. Flomoxef is effective against CE in vitro, and some clinical data on its demonstrated effectiveness against CE bloodstream infections (BSIs exists.Patients and methods: We conducted a retrospective study on adults with BSI caused by flomoxef-susceptible CE to investigate the efficacy of flomoxef compared with that of ertapenem. The outcome was evaluated with propensity score-based matching and logistic regression analysis.Results: Demographic and clinical characteristics of patients treated with flomoxef (n = 58 or ertapenem (n = 188 were compared. In the multivariate analysis, severe sepsis (adjusted odds ratio [AOR] = 3.84; 95% confidence interval [CI], 1.16–12.78; p = 0.03, high BSI mortality score (AOR = 5.59; 95% CI, 2.37–13.21; p < 0.01, ultimately or rapidly fatal comorbidity (AOR = 10.60; 95% CI, 3.43–32.75; p < 0.01, and pneumonia (AOR = 10.11; 95% CI, 3.43–29.81; p < 0.01 were independently associated with 28-day mortality. Using propensity scores, 58 flomoxef-treated patients were matched to 116 ertapenem-treated patients. There were no intergroup differences in BSI severity, comorbidity, or BSI sources. The 28-day mortality rates (20.7% vs 13.8%, p = 0.28 did not differ significantly.

  5. X-ray Discovery Points to Location of Missing Matter (United States)


    Using observations with NASA's Chandra X-ray Observatory and ESA's XMM-Newton, astronomers have announced a robust detection of a vast reservoir of intergalactic gas about 400 million light years from Earth. This discovery is the strongest evidence yet that the "missing matter" in the nearby Universe is located in an enormous web of hot, diffuse gas. This missing matter — which is different from dark matter -- is composed of baryons, the particles, such as protons and neutrons, that are found on the Earth, in stars, gas, galaxies, and so on. A variety of measurements of distant gas clouds and galaxies have provided a good estimate of the amount of this "normal matter" present when the universe was only a few billion years old. However, an inventory of the much older, nearby universe has turned up only about half as much normal matter, an embarrassingly large shortfall. The mystery then is where does this missing matter reside in the nearby Universe? This latest work supports predictions that it is mostly found in a web of hot, diffuse gas known as the Warm-Hot Intergalactic Medium (WHIM). Scientists think the WHIM is material left over after the formation of galaxies, which was later enriched by elements blown out of galaxies. "Evidence for the WHIM is really difficult to find because this stuff is so diffuse and easy to see right through," said Taotao Fang of the University of California at Irvine and lead author of the latest study. "This differs from many areas of astronomy where we struggle to see through obscuring material." To look for the WHIM, the researchers examined X-ray observations of a rapidly growing supermassive black hole known as an active galactic nucleus, or AGN. This AGN, which is about two billion light years away, generates immense amounts of X-ray light as it pulls matter inwards. Lying along the line of sight to this AGN, at a distance of about 400 million light years, is the so-called Sculptor Wall. This "wall", which is a large diffuse

    Full Text Available Abstract Background China is currently facing a rapid and widespread increase in human immunodeficiency virus (HIV/acquired immunodeficiency syndrome (AIDS. The activities of female sex workers (FSWs have contributed to the mounting epidemic of HIV/AIDS and other sexually transmitted diseases (STDs. Therefore, this study aimed to assess the HIV/AIDS-related knowledge, attitude and risk behaviors among FSWs operating in Shanghai China. Methods A cross-sectional study was conducted in five districts of Shanghai, including three suburbs and two downtown locales. We adopted a cluster randomized sampling method to obtain ten geographic sites which consisted of one or more communities/villages proximal to a location where FSWs were accessible. A total of 324 FSWs from 109 Xitou Fang, massage parlors and hair salons who explicitly provided sexual services were enrolled in the study. Each participant completed a questionnaire survey and interview aimed to collect information on the individual's knowledge, attitude, and behaviors associated with risk for HIV/AIDs. Results The overall correct answer rate of HIV/AIDS-related knowledge was 60.8%, and the knowledge of FSWs from downtown areas was significantly higher than those from suburban areas (P P Conclusions Based on the findings from our survey, we advise that promotion of HIV/AIDS-related knowledge be targeted towards FSWs in Shanghai, especially those operating in the suburbs. HIV prevention efforts, such as urging constant condom usage with both clients and steady partners, should be sustained and reinforced among the female sex workers population.

  7. Evaluation of Biochemical Changes in Experimental Animals Treated with Some Anticancer and Radiosynthetizers

    Cancer constitutes the largest cause of mortality in the world and claims over 6 million lives every year (Abdullaev et al. 2000).It is a disease in which cellular growth regulatory networks are disrupted(Chen et al.2003). An extremely promising strategy for cancer prevention today is chemo prevention, which is defined as the use of synthetic or natural agents (alone or in combination) to block the development of cancer in humans (Gupta et al. 2004). Most of anticancer drugs have side effects on human normal cells when they were used to treat tumor cells (Bi and Jiang ,2006).Therefore cancer drugs development has moved from conventional cytotoxic chemotherapeutics to a more mechanism-based targeted approach towards the common goal of tumor growth arrest (McLaughlin and La Thangue 2004). Histones are a family of nuclear proteins that interact with DNA, resulting in DNA being wrapped around a core of histone octamer within the nucleosome (Rasheed et al. 2008).They may act through the transcriptional reactivation of dormant tumor suppressor genes and they also modulate expression of several other genes related to cell cycle, apoptosis, and angiogenesis (Shankar ans Srivastava, 2008). Histone acetylation is a reversible process: histone acetyl transferases (HAT) transfer the acetyl moiety from acetyl coenzyme A to the lysine, and histone de acetylases (HDAC) remove the acetyl groups reestablishing the positive charge in the histones (Fang, 2005).In particular, imbalance in histone acetylation can lead to changes in chromatin structure and transcriptional dysregulation of genes that are involved in the control of proliferation, cell-cycle progression, differentiation and/or apoptosis

  8. Wenjing decoction (herbal medicine) for the treatment of primary dysmenorrhea: a systematic review and meta-analysis. (United States)

    Gao, Li; Jia, Chunhua; Zhang, Heng; Ma, Cuilan


    Wenjing decoction is a well-accepted traditional Chinese medicine for the treatment of primary dysmenorrhea in East Asia, but its clinical effectiveness and risk have not been adequately assessed. In this paper, we conducted a systematic review and meta-analysis to evaluate the efficacy of Wenjing decoction for the treatment of primary dysmenorrhea. Eight databases were used in our research: the Cochrane Library, the Web of Science, PubMed, EMBASE, the Chinese Biomedical Literature Database (CBM), the Chinese National Knowledge Infrastructure (CNKI), the Chinese Scientific Journal Database, and the Wan-fang Database. The following search terms were used: (Wenjing decoction OR Wenjing formula OR Wenjing tang) AND (primary dysmenorrhea OR dysmenorrhea OR painful menstruation) AND (randomized controlled trial). No language limitation was used. A total of 18 studies, including 1736 patients, were included in the meta-analysis. Wenjing decoction was shown to be significantly better than nonsteroidal anti-inflammatory drugs for the improvement of primary dysmenorrhea according to the clinical effective rate (RR 1.41, 95% CI 1.24-1.61), the visual analogue scale (MD -1.77, 95% CI -2.69 to -0.84), and the pain scale for dysmenorrhea (MD -1.81, 95% CI -2.41 to -1.22). The results supported the clinical use of Wenjing decoction for the treatment of primary dysmenorrhea. However, the quality of the evidence for this finding was low due to a high risk of bias in the included studies. Therefore, well-designed randomized controlled trials are still needed to further evaluate the efficacy of Wenjing decoction for the treatment of primary dysmenorrhea.

  9. Efficacy, acceptability and tolerability of 8 atypical antipsychotics in Chinese patients with acute schizophrenia: A network meta-analysis. (United States)

    We aimed to create hierarchies of the efficacy, acceptability and tolerability of eight atypical antipsychotics in the treatment of Chinese patients with acute schizophrenia. We systematically searched for RCT articles published between January 1st 2005 and December 31st 2014 in electronic databases (Medline, Pubmed, Embase, the Cochrane Library and for studies in English and the China National Knowledge Infrastructure, Wan Fang, and VIP Information/Chinese Scientific Journals Database for studies in Chinese). The primary outcome was efficacy, as measured by the change of PANSS total score. Pairwise comparisons were performed using random-effects model by the Dersimonian-Laird method and network meta-analyses were performed in a Bayesian set. Sixty high-quality RCTs with 6418 participants were included. A pattern of superiority from olanzapine, paliperidone and amisulpride was seen in the primary outcome. Only paliperidone was found better than aripiprazole (odds ratio, 0.49 [95% credible intervals, 0.25 to 0.99]), ziprasidone (0.42 [0.21 to 0.85]) and quetiapine (0.36 [0.13 to 0.93]) in terms of all-cause discontinuation. The best and worst drugs in terms of weight gain, EPS and somnolence were aripiprazole and olanzapine, clozapine and amisulpride, aripiprazole and clozapine, respectively. The rank of efficacy did not change substantially in sensitivity analyses or in meta-regressions. Our findings provided the hierarchies of eight antipsychotics in efficacy, acceptability and tolerability. These findings are expected to help Chinese clinicians to select the appropriate antipsychotic drug for their patients. Copyright © 2017 Elsevier B.V. All rights reserved.

  10. Meta-analysis of vaccine effectiveness of mumps-containing vaccine under different immunization strategies in China. (United States)

    Wang, Huaqing; Hu, Yongmei; Zhang, Guomin; Zheng, Jingshan; Li, Li; An, Zhijie


    To evaluate vaccine effectiveness (VE) of mumps-containing vaccine (MuV) under different immunization strategies. We conducted Medline, Embase, China National Knowledge Internet (CNKI), and Wan Fang Database (WF) searches for Chinese and English language articles describing studies of mumps VE in a Chinese population. Evaluated articles were scored on quality using the Newcastle-Ottawa Scale. Meta-analysis was conducted using random effects models. Sensitivity analysis, subgroup analysis and meta-regression were conducted to explore heterogeneity. A total of 32 studies in 19 papers were included; 14 were case-control studies, and 18 were cohort studies. Half of the studies were of high quality; 41% were of moderate quality. The overall VE for mumps containing vaccine (either one dose or two doses) was 85% (95% CI 76-90%) for cohort studies and 88% (95% CI 82-92%) for case-control studies. Using random effects meta-regression we found significant differences in some study covariates; for instance, VE varied by population (VE=88% in day care versus 69% in pupil, p=0.008) and emergency versus routine immunization (VE=80% for routine immunization versus 95% for emergency immunization, p=0.041). However, these results must be interpreted with caution due to the low number of studies in subgroups, with the permutation test giving non-significant results that indicated that the results may be due to chance. MuV provides good protection from mumps infection. Further studies of mumps VE with larger sample sizes enabling subgroup analyses will be needed to confirm our findings.

  11. An algorithm of discovering signatures from DNA databases on a computer cluster. (United States)

    Lee, Hsiao Ping; Sheu, Tzu-Fang


    Signatures are short sequences that are unique and not similar to any other sequence in a database that can be used as the basis to identify different species. Even though several signature discovery algorithms have been proposed in the past, these algorithms require the entirety of databases to be loaded in the memory, thus restricting the amount of data that they can process. It makes those algorithms unable to process databases with large amounts of data. Also, those algorithms use sequential models and have slower discovery speeds, meaning that the efficiency can be improved. In this research, we are debuting the utilization of a divide-and-conquer strategy in signature discovery and have proposed a parallel signature discovery algorithm on a computer cluster. The algorithm applies the divide-and-conquer strategy to solve the problem posed to the existing algorithms where they are unable to process large databases and uses a parallel computing mechanism to effectively improve the efficiency of signature discovery. Even when run with just the memory of regular personal computers, the algorithm can still process large databases such as the human whole-genome EST database which were previously unable to be processed by the existing algorithms. The algorithm proposed in this research is not limited by the amount of usable memory and can rapidly find signatures in large databases, making it useful in applications such as Next Generation Sequencing and other large database analysis and processing. The implementation of the proposed algorithm is available at

The therapeutic landscape is rapidly changing with the development of novel agents in recent decades, such as anti-PD-1 agents, anti-CTLA-4 agents, and BRAF inhibitors. However, since most of these novel agents are very expensive, not all patients can afford them. Apatinib is a novel oral small-molecule tyrosine kinase inhibitor targeting the intracellular domain of vascular endothelial growth factor receptor 2 (VEGFR-2 and may also be effective on Ret, c-KIT, and c-src. Temozolomide (TMZ is a second-generation alkylating agent and a cytotoxic drug for melanoma treatment. In this work, we reported a case of metastatic melanoma with an excellent response to apatinib/TMZ combination therapy with progression-free survival for more than one year. This patient showed high expression of CD117, VEGFR-3, and KIT mutation in exon 11, suggesting that apatinib may induce clinical response via inhibiting VEGFR and c-KIT. Apatinib/TMZ combination therapy could be a new option for the treatment of advanced melanoma with KIT mutation.

  13. Pediatric Tuina for promoting growth and development of preterm infants: A protocol for the systematic review of randomized controlled trail. (United States)

    Zhang, Xinghe; Guo, Taipin; Zhu, Bowen; Gao, Qing; Wang, Hourong; Tai, Xiantao; Jing, Fujie


    Preterm infants are babies born alive before 37 weeks. Many survived infants concomitant with defects of growth and development, a lifetime of disability usually as following when insufficient intervention. In early intervention of preterm infants, pediatric Tuina shows good effect in many Chinese and some English clinical trials. This systematic review is aimed to evaluate the efficacy and safety of pediatric Tuina for promoting growth and development of preterm infants. The electronic databases of Cochrane Library, MEDLINE, EBASE, Web of Science, Springer, World Health Organization International Clinical Trials Registry Platform, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Wan-fang database, Chinese Scientific Journal Database, and other databases will be searched from establishment to April 1, 2018. All published randomized controlled trials (RCTs) about this topic will be included. Two independent researchers will operate article retrieval, screening, quality evaluation, and data analyses by Review Manager (V.5.3.5). Meta-analyses, subgroup analysis, and/or descriptive analysis will be performed based on included data conditions. High-quality synthesis and/or descriptive analysis of current evidence will be provided from weight increase, motor development, neuropsychological development, length of stay, days of weight recovery to birthweight, days on supplemental oxygen, daily sleep duration, and side effects. This study will provide the evidence of whether pediatric Tuina is an effective early intervention for preterm infants. There is no requirement of ethical approval and informed consent, and it will be in print or published by electronic copies. This systematic review protocol has been registered in the PROSPERO network (No. CRD42018090563).

  14. Wet cupping therapy for treatment of herpes zoster: a systematic review of randomized controlled trials. (United States)

    Cao, Huijuan; Zhu, Chenjun; Liu, Jianping


    Wet cupping is a traditional Chinese medicine therapy commonly used in treating herpes zoster in China, and clinical studies have shown that wet cupping may have beneficial effect on herpes zoster compared with Western medication. We included randomized controlled trials (RCTs) on wet cupping for herpes zoster. We searched PubMed, the Cochrane Library (Issue 3, 2008), China Network Knowledge Infrastructure (CNKI), Chinese Scientific Journals Fulltext Database VIP, and Wan Fang Database. All searches ended in February 2009. Two authors extracted data and assessed the trials' quality independently. RevMan 5.0.18 software (The Cochrane Collaboration, The Nordic Cochrane Centre, Copenhagen, Denmark) was used for data analysis with effect estimate presented as relative risk (RR) and mean difference (MD) with a 95% confidence interval (CI). Eight RCTs involving 651 patients were included, and the methodological quality of trials was generally fair in terms of randomization, blinding, and intention-to-treat analysis. Meta-analyses showed wet cupping was superior to medication in the number of cured patients (RR 2.49, 95% CI 1.91 to 3.24, P cupping plus medication was significantly better than medication alone on number of cured patients (RR 1.93, 95% CI 1.23 to 3.04, P = .005) but demonstrated no difference in symptom improvement (RR 1.00, 95% CI 0.92 to 1.08, P = .98). There were no serious adverse effects related to wet cupping therapy in the included trials. Wet cupping appears to be effective in the treatment of herpes zoster. However, further large, rigorously designed

    At present, the diagnosis-related groups-based prospective payment system (DRG-PPS) that has been implemented in China is merely a prototype called the simplified DRG-PPS, which is known as the 'ceiling price for a single disease'. Given that studies on the effects of a simplified DRG-PPS in China have usually been controversial, we aim to synthesize evidence examining whether DRGs can reduce medical costs and length of stay (LOS) in China. Data were searched from both Chinese [Wan Fang and China National Knowledge Infrastructure Database (CNKI)] and international databases (Web of Science and PubMed), as well as the official websites of Chinese health departments in the 2004-2016 period. Only studies with a design that included both experimental (with DRG-PPS implementation) and control groups (without DRG-PPS implementation) were included in the review. The studies were based on inpatient samples from public hospitals distributed in 12 provinces of mainland China. Among them, 80.95% (17/21) revealed that hospitalization costs could be reduced significantly, and 50.00% (8/16) indicated that length of stay could be decreased significantly. In addition, the government reports showed the enormous differences in pricing standards and LOS in various provinces, even for the same disease. We conclude that the simplified DRGs are useful in controlling hospitalization costs, but they fail to reduce LOS. Much work remains to be done in China to improve the simplified DRG-PPS. © The Author 2017. Published by Oxford University Press on behalf of Royal Society of Tropical Medicine and Hygiene.

  16. Generation and electric control of spin-valley-coupled circular photogalvanic current in WSe2 (United States)

    Yuan, Hongtao; Hwang, Harold Y.; Cui, Yi


    Compared to the weak spin-orbit-interaction (SOI) in graphene, layered transitionmetal chalcogenides MX2 have heavy 4d/5d elements with strong atomic SOI, providing a unique way to extend functionalities of novel spintronics and valleytronics devices. Such a valley polarization achieved via valley-selective circular dichroism has been predicted theoretically and demonstrated with optical experiments in MX2 systems. Despite the exciting progresses, the generation of a valley/spin current by valley polarization in MX2 remains elusive and a great challenge. A spin/valley current in MX2 compounds caused by such a valley polarization has never been observed, nor its electric-field control. In this talk, we demonstrated, within an electric-double-layer transistor based on WSe2, the manipulation of a spin-coupled valley photocurrent whose direction and magnitude depend on the degree of circular polarization of the incident radiation and can be further greatly modulated with an external electric field. Such room temperature generation and electric control of valley/spin photocurrent provides a new property of electrons in MX2 systems, thereby enabling new degrees of control for quantum-confined spintronics devices.

The aim of this study was to investigate the potential of glyceryl monoolein (GMO cubosomes as lipid nanocarriers to improve the oral efficacy of AmB. Antifungal efficacy was determined in vivo in rats after oral administration, to investigate its therapeutic use. The human colon adenocarcinoma cell line (Caco-2 was used in vitro to evaluate transport across a model of the intestinal barrier. In vivo antifungal results showed that AmB, loaded in GMO cubosomes, could significantly enhance oral efficacy, compared against Fungizone®, and that during a 2 day course of dosage 10 mg/kg the drug reached effective therapeutic concentrations in renal tissue for treating fungal infections. In the Caco-2 transport studies, GMO cubosomes resulted in a significantly larger amount of AmB being transported into Caco-2 cells, via both clathrin- and caveolae-mediated endocytosis, but not macropinocytosis. These results suggest that GMO cubosomes, as lipid nanovectors, could facilitate the oral delivery of AmB.Keywords: glyceryl monoolein cubosomes, oral delivery, amphotericin B, antifungal activity, absorption mechanism

Methods: A series of 39 novel 2-benzylidene-indanone structural derivatives were synthesized and evaluated for anti-inflammatory activity in lipopolysaccharide (LPS-stimulated murine primary macrophages. Results: Most of the obtained compounds effectively inhibited the LPS-induced expression of IL-6 and TNF-α. The most active compound, 8f, was found to significantly reduce LPS-induced pulmonary inflammation, as reflected by reductions in the concentration of total protein, inflammatory cell count, as well as the lung wet/dry ratio in bronchoalveolar lavage (BAL fluid. Furthermore, 8f effectively inhibited mRNA expression of several inflammatory cytokines after LPS challenge in vitro and in vivo. Administration of 8f also blocked LPS-induced activation of the proinflammatory NF-κB/MAPK signaling pathway. Conclusion: The simple synthetic preparation and biological properties of these derivatives make these 2-benzylidene-indanone scaffolds promising new entities for the development of anti-inflammatory therapeutics for the treatment of acute lung injury.

    Full Text Available Abstract Background Drugs to protect the liver are frequently prescribed in some countries as part of treatment for tuberculosis. The biological rationale is not clear, they are expensive and may do harm. We conducted a systematic review to a describe the ingredients of "liver protection drugs"; and b compare the evidence base for the policy against international standards. Methods We searched international medical databases (MEDLINE, EMBASE, LILACS, CINAHL, Cochrane Central Register of Controlled Trials, and the specialised register of the Cochrane Infectious Diseases Group and Chinese language databases (CNKI, VIP and WanFang to April 2007. Our inclusion criteria were research papers that reported evaluating any liver protection drug or drugs for preventing liver damage in people taking anti-tuberculosis treatment. Two authors independently categorised and extracted data, and appraised the stated methods of evaluating their effectiveness. Results Eighty five research articles met our inclusion criteria, carried out in China (77, India (2, Russia (4, Ukraine (2. These articles evaluated 30 distinct types of liver protection compounds categorised as herbal preparations, manufactured herbal products, combinations of vitamins and other non-herbal substances and manufactured pharmaceutical preparations. Critical appraisal of these articles showed that all were small, poorly conducted studies, measuring intermediate outcomes. Four trials that were described as randomised controlled trials were small, had short follow up, and did not meet international standards. Conclusion There is no reliable evidence to support prescription of drugs or herbs to prevent liver damage in people on tuberculosis treatment.

  20. [Preliminary investigation on the materia medica of the Zhuang ethnic group]. (United States)

    Rong, Xiao-Xiang; Li, Gui


    By Zhuang materia medica, it refers to application of medicines under the instructions of medical theory of Zhuang ethnic group. By studying the pronunciation of the Zhuang language for the terms "zhu yu", "bai jiu", and "mi gu" included in the shan hai jing nan shan jing (The Classic of Southern Mountain in Classic of Seas and Mountains) carried out by the Zhuang scholar Qin Bao-lin, it was concluded that the Zhuang minority already applied medicines early in the pre-Qin period. Through extensive cultural communication in different regions in the Wei-Jin-Southern-Northern Dynasties, the medicinal experiences of the Zhuang ethnic group appeared in ancient literature. The antidotes in Zhou hou fang (Handbook of Prescriptions for Emergency), for instance, were mostly coming from the Southern Ridge area. Since the Sui-Tang Dynasties, many materia medica recorded in the herbal works and regional gazetteers, and Annals such as the Guangxi Annals, Gazetteer of Nanning County, and Gazetteer of Liuzhou County, Gazetteer of Binzhou County etc., also carry medicines such as Cinnamom twigs and bark, and mangosteen etc., which are similar to those of the Zhuang medicines. In the Republican period, many manuscripts of Zhuang medicines appeared. After 1949, many institutions of Zhuang medicine were set up successively, including The Nanning Medical Institute, The Medical Institute of Wuzhou, The Medical Institute of Guilin. Systematic researches were also done, with publication of a series of works on Zhuang materia medica. Reformation of part of the prescription forms of Zhuang medicine were also accomplished.
