Abstract

We report a measurement of the differential cross section for the gamman-->pi- p process from the CLAS detector at Jefferson Laboratory in Hall B for photon energies between 1.0 and 3.5 GeV and pion center-of-mass (c.m.) angles (thetac.m.) between 50 degrees and 115 degrees. We confirm a previous indication of a broad enhancement around a c.m. energy ([sqrt]s) of 2.1 GeV at thetac.m.=90 degrees in the scaled differential cross section s7dsigma/dt and a rapid falloff in a center-of-mass energy region of about 400 MeV following the enhancement. Our data show an angular dependence of this enhancement as the suggested scaling region is approached for thetac.m. from 70 degrees to 105 degrees.

Abstract

The genus Hydropsyche is reviewed from India. Three new species are described and illustrated belonging to genus Hydropsyche. The newly described species are Hydropsyche curvata sp. nov., H. hajinensis sp. nov., both from Jammu Kashmir, and H. golitarensis sp. nov. from Sikkim. Hydropsyche quadrata Malicky Chantaramongkol 2000 (from Sikkim), H. augeias Malicky Chantaramongkol 2000 (from Uttarakhand) and H. camillus Malicky Chantaramongkol 2000 (from Sikkim and Himachal Pradesh) are reported for the first time from India. Hydropsyche athamas Malicky Chantaramongkol 2000, H. homunculus Schmid 1965, and H. harpagofalcata Mey 1995 are also redescribed and reported for the first time from India. Hydropsyche nuristanica Schmid 1963 (from Jammu and Kashmir) and H. rakshakaha Oláh 1994 (from Jammu and Kashmir, Himachal Pradesh, Uttarakhand, and West Bengal) are reported from these states for the first time. Hydropsyche charon Malicky Chantaramongkol 2000, from Uttarakhand, H. appendicularis Martynov 1931, and H. pallipenne Banks 1938 are also redescribed and reported from Himachal Pradesh. Hydropsyche claviformis Mey 1996 is also redescribed based on a specimen from Sikkim. Furthermore, the male is redescribed and a neotype is designated for Hydropsyche asiatica Ulmer 1905. Hydropsyche chotanagpurensis is a nomen novum, replacing junior homonym Hydropsyche ulmeri (Martynov 1935). With these additions, the total number of Indian species for genus Hydropsyche is now 54. A catalogue of known Indian species is also given.

Abstract

We measured the ratios of electroproduction cross sections from a proton target for three exclusive meson-baryon final states: ΛK(+), pπ(0), and nπ(+), with the CLAS detector at Jefferson Lab. Using a simple model of quark hadronization, we extract qq creation probabilities for the first time in exclusive two-body production, in which only a single qq pair is created. We observe a sizable suppression of strange quark-antiquark pairs compared to nonstrange pairs, similar to that seen in high-energy production.

Abstract

In the area of water purification, nanotechnology provides efficient removal of pollutants and germs. Electrospun nanofibers membrane has a potential for water purification due to its high large surface area, and good mechanical strength. In the present study, PAMAM dendrimers composite nylon-6 nanofibers membrane was prepared by crosslinking method using glutaraldehyde. Modified membrane has drastically improved water purification efficiency. Further, the efficacy of the modified membrane can be renewed by mere exposure of the saturated membrane with the solution having acidic pH. The modified membrane can be used as an effective tool for water purification.

Abstract

We have measured cross sections for the γ(3)He → pd reaction at photon energies of 0.4-1.4 GeV and a center-of-mass angle of 90°. We observe dimensional scaling above 0.7 GeV at this center-of-mass angle. This is the first observation of dimensional scaling in the photodisintegration of a nucleus heavier than the deuteron.

Abstract

Exclusive π(0) electroproduction at a beam energy of 5.75 GeV has been measured with the Jefferson Lab CLAS spectrometer. Differential cross sections were measured at more than 1800 kinematic values in Q(2), x(B), t, and ϕ(π), in the Q(2) range from 1.0 to 4.6  GeV(2), -t up to 2  GeV(2), and x(B) from 0.1 to 0.58. Structure functions σ(T)+ϵσ(L), σ(TT), and σ(LT) were extracted as functions of t for each of 17 combinations of Q(2) and x(B). The data were compared directly with two handbag-based calculations including both longitudinal and transversity generalized parton distributions (GPDs). Inclusion of only longitudinal GPDs very strongly underestimates σ(T)+ϵσ(L) and fails to account for σ(TT) and σ(LT), while inclusion of transversity GPDs brings the calculations into substantially better agreement with the data. There is very strong sensitivity to the relative contributions of nucleon helicity-flip and helicity nonflip processes. The results confirm that exclusive π(0) electroproduction offers direct experimental access to the transversity GPDs.

Abstract

We report on the first measurement of the F(2) structure function of the neutron from the semi-inclusive scattering of electrons from deuterium, with low-momentum protons detected in the backward hemisphere. Restricting the momentum of the spectator protons to ≲100 MeV/c and their angles to ≳100° relative to the momentum transfer allows an interpretation of the process in terms of scattering from nearly on-shell neutrons. The F(2)(n) data collected cover the nucleon-resonance and deep-inelastic regions over a wide range of Bjorken x for 0.65

Author

Pandher MS and Saini MS

Abstract

The genus Kisaura Ross, 1956 (Trichoptera, Philopotamidae, Philopotaminae) is reported from India the first time. Six new species are described and illustrated: Kisaura elongatasp. n., Kisaura eloctsp. n., Kisaura clavatasp. n., Kisaura gangtokensissp. n., Kisaura truncatasp. n., all from Gangtok (Sikkim) and Kisaura himachalicasp. n. from Barot (Himachal Pradesh). Male genitalia of this genus are distinguishable from those of other genera of the family by the pair of long lateral processes of tergum X, the well-developed mesoventral plates between two segments of the inferior appendages, and by the brush-like row of dark setae on the inner surfaces of the terminal segments (harpago) of the inferior appendages.

Abstract

We report the first measurement of the transverse momentum dependence of double-spin asymmetries in semi-inclusive production of pions in deep-inelastic scattering off the longitudinally polarized proton. Data have been obtained using a polarized electron beam of 5.7 GeV with the CLAS detector at the Jefferson Lab (JLab). Modulations of single spin asymmetries over the azimuthal angle between lepton scattering and hadron production planes ϕ have been measured over a wide kinematic range in Bjorken x and virtual photon squared four-momentum Q2. A significant nonzero sin2ϕ single spin asymmetry was observed for the first time indicating strong spin-orbit correlations for transversely polarized quarks in the longitudinally polarized proton.

Abstract

Because of their long lifetimes, the ω and ϕ mesons are the ideal candidates for the study of possible modifications of the in-medium meson-nucleon interaction through their absorption inside the nucleus. During the E01-112 experiment at the Thomas Jefferson National Accelerator Facility, the mesons were photoproduced from 2H, C, Ti, Fe, and Pb targets. This Letter reports the first measurement of the ratio of nuclear transparencies for the e+e- channel. The ratios indicate larger in-medium widths compared with what have been reported in other reaction channels. The absorption of the ω meson is stronger than that reported by the CBELSA-TAPS experiment and cannot be explained by recent theoretical models.

Abstract

We report a measurement of the differential cross section for the gamman-->pi- p process from the CLAS detector at Jefferson Laboratory in Hall B for photon energies between 1.0 and 3.5 GeV and pion center-of-mass (c.m.) angles (thetac.m.) between 50 degrees and 115 degrees. We confirm a previous indication of a broad enhancement around a c.m. energy ([sqrt]s) of 2.1 GeV at thetac.m.=90 degrees in the scaled differential cross section s7dsigma/dt and a rapid falloff in a center-of-mass energy region of about 400 MeV following the enhancement. Our data show an angular dependence of this enhancement as the suggested scaling region is approached for thetac.m. from 70 degrees to 105 degrees.

Abstract

The neutron elastic magnetic form factor was extracted from quasielastic electron scattering on deuterium over the range Q;{2}=1.0-4.8 GeV2 with the CLAS detector at Jefferson Lab. High precision was achieved with a ratio technique and a simultaneous in situ calibration of the neutron detection efficiency. Neutrons were detected with electromagnetic calorimeters and time-of-flight scintillators at two beam energies. The dipole parametrization gives a good description of the data.

Abstract

We report on the results of the first measurement of exclusive f&#95;{0}(980) meson photoproduction on protons for E&#95;{gamma}=3.0-3.8 GeV and -t=0.4-1.0 GeV2. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. The resonance was detected via its decay in the pi;{+}pi;{-} channel by performing a partial wave analysis of the reaction gammap-->ppi;{+}pi;{-}. Clear evidence of the f&#95;{0}(980) meson was found in the interference between P and S waves at M&#95;{pi;{+}pi;{-}} approximately 1 GeV. The S-wave differential cross section integrated in the mass range of the f&#95;{0}(980) was found to be a factor of about 50 smaller than the cross section for the rho meson. This is the first time the f&#95;{0}(980) meson has been measured in a photoproduction experiment.

Abstract

The aim of this work was to investigate the potential of water hyacinth (WH) spiked with cow dung (CD) into vermicompost. Five vermireactors containing WH and CD in different ratios, were run under laboratory conditions for 147 days. The maximum worm growth was recorded in CD alone. Worms grew and reproduced favourably in 25% WH+75% CD feed mixture. Greater proportion of WH in feed mixture significantly affected the biomass gain, hatchling numbers and numbers of cocoons produced during experiments. In all the vermireactors, there was significant decrease in pH, TOC and C:N ratio, but increase in TKN, TK and TAP at the end. The heavy metals content in the vermicomposts was lower than initial feed mixtures. The results indicated that WH could be potentially useful as raw substrate in vermicomposting if mixed with up to 25% in cow dung (on dry weight basis).

Abstract

In the light of recognition of an increased need for secure mental health provision both at a local and national level, a 12-bed low secure forensic rehabilitation unit, Hillis Lodge, was opened in Birmingham in 2001. The aim of this study was to investigate characteristics of patients referred to this service. A retrospective case note survey was undertaken of all referrals to Hillis Lodge between August 2000 and April 2004. A comparison was then made between the accepted group and those not accepted for admission to identify characteristics that may be associated with admission to a low secure forensic unit. For the referred sample, mean age was 38 years (range 23-65 years, SD = 9.17) and in 86.4% of cases the primary diagnosis was schizophrenia. Those accepted were more likely to be detained under Part III sections of the Mental Health Act 1983 and have a greater number of previous convictions. By identifying need in this particular patient sample, this study has helped to inform the assessment process and treatment programmes in a low secure forensic rehabilitation service.

38. Soft tissue coverage of the knee joint following burns.

Author

Abstract

Full-thickness burns around the knee joint are usually associated with exposure of bone, tendon or ligaments. Following excision of the deep burns, there is no viable wound bed to which skin grafts can be applied. Although vacuum-assisted closure has been used to encourage granulation tissue, exposure of the tendons and ligaments following excision usually requires muscle flaps or fasciocutaneous flaps.

Abstract

Secretory immunoglobulin A (IgA) is the principle antibody protecting against pathogens at mucosal sites. Ethanol (EtOH) exposure is related to adverse effects on the enterocyte cytoskeleton. The aim of this study was to assess the role of normal cytoskeletal function on IgA transcytosis and its modulation by EtOH by studying Madin-Darby canine kidney (MDCK) cells transfected with the polyimmunoglobulin receptor. MDCK cells were grown as confluent monolayers and treated with 5 per cent EtOH, cytochalasin D (Cyto-D, a cytoskeletal destabilizer), or pretreatment with prostaglandin E2 (a cytoskeletal stabilizer) followed by EtOH. Media alone served as control. IgA was then added to the basolateral side of the chambers, and apical samples were taken for enzyme-linked immunosorbent assay analysis at 0, 3, and 12 hours. Dimeric IgA transcytosis increased in all groups and was significantly depressed by 5 per cent EtOH and Cyto-D. Morphological slides revealed aggregation of actin after Cyto-D treatment. Prostaglandin E2 prevented the decrease in IgA transcytosis seen otherwise with 5 per cent EtOH treatment. We conclude that IgA transcytosis is dependent on actin microfilaments of the cytoskeleton. Decreased IgA transport may lead to mucosal immunodeficiency and infectious complications after EtOH exposure.

Abstract

Immunoinflammatory responses after shock and major trauma are characterized by an early hyperinflammatory response and later by compensatory anti-inflammatory host mediator production. This late phase is associated with depressed immune function that has been causally linked with post-traumatic infectious complications and late organ failure. Gut barrier failure is noted in this setting and may be an important source of nosocomial infections and organ failure. Secretory immunoglobulin A (sIgA) is the predominant immunoglobin at mucosal surfaces and is difficult to quantify in luminal secretions. Attempts to normalize sIgA concentrations may not be accurate and/or may not be applicable in vivo. A method using mucosal immunization with cholera toxin (ChT) to normalize gut sIgA levels was used to assess serial changes in sIgA after hemorrhagic shock (HS) in rodents. Total and anti-ChT sIgA levels were highly variable in both HS and sham animals. However, when normalized using the specific anti-ChT/total sIgA ratio, differences were clearly evident. This ratio was depressed between 3 and 10 days post-HS. The specific anti-ChT/total sIgA ratio is a reliable index of secretory antibody at gut luminal surfaces. Impaired mucosal immune function occurred in a time frame consistent with development of late nosocomial infections. This may be important mechanistically in the development of these infectious complications.

Abstract

Secretory immunoglobulin A (sIgA) is the principal antibody protecting against pathogens in the respiratory tract and other mucosal surfaces. Nosocomial pneumonias are frequent after injury and critical illness and are often due to enteric pathogens. The aim of this study was to assess the relative effect of hemorrhagic shock (HS) on mucosal immunity at intestinal and respiratory mucosal sites. Fisher rats were immunized intragastrically with dinitrophenylated (DNP) Pneumococcus (Pn). Three weeks later, animals were subjected to sham treatment or HS. The animals were then rechallenged with DNP-Pn 1 or 3 days later. Animals were sacrificed 7 days later, and bronchoalveolar and gastric lavage was performed. Total and anti-DNP-specific sIgA were quantitated from these secretions by enzyme-linked immunosorbent assay. There was a significant decrease in DNP-Pn-specific sIgA at 72 hours after HS, which was not present in animals at 24 hours after HS. This was most profound in bronchoalveolar lavage specimens. We conclude that impaired mucosal defense against gut-derived antigens after HS may be important mechanistically for the development of posttraumatic pneumonia and other mucosally related infectious complications.

Abstract

The hydrolysis of phosphoric monoesters by acid phosphatases is thought to proceed via the formation of a phosphoenzyme intermediate, but no stereochemical evidence exists on this point. We have carried out the transphosphorylation from phenyl (R)-[16O, 17O, 18O] phosphate to (S)-propane-1,2-diol in the presence of homogeneous bovine liver acid phosphatase, and have found that the reaction proceeds with greater 90% overall retention of configuration at phosphorus. This stereochemical course of phospho transfer during the enzyme-catalyzed reaction of the phosphoric monoester is consistent with a double displacement mechanism in which each step proceeds with inversion of the stereochemistry at phosphorus, and is similar to the behavior of the bacterial alkaline phosphatase.

Abstract

We describe an assay method using choline O-phosphate as a substrate for the measurement of serum prostatic acid phosphatase as an aid in the diagnosis of prostatic cancer. Choline phosphate is hydrolyzed by homogeneous prostatic acid phosphatase, and it is also hydrolyzed by an acid phosphatase present in the serum of prostatic carcinoma patients. In contrast, serum samples from apparently healthy persons do not exhibit any significant choline O-phosphate phosphatase activity. There is a correlation of 98% (n = 46) between choline O-phosphate phosphatase activity and typical measurement for prostatic acid phosphatase activity carried out using thymolphthalein monophosphate as the substrate. The new method appears to be as accurate as colorimetric methods based on thymolphthalein phosphate as a substrate. Although not as sensitive as immunologically based methods, the present technique for measuring prostatic acid phosphatase activity using choline phosphate as a substrate is economical and relatively simple.

Abstract

We describe the synthesis of a long-chain monoamide derivative of L(+)-tartaric acid and its attachment to Sepharose 4B. Procedures are then described for use of this material in purifying human prostatic and (for the first time) canine prostatic acid phosphatases to constant specific activity and electrophoretic homogeneity. Depending on sample size, such purification is possible in one step, and is clearly faster and more efficient than are previously described methods. These materials and procedures have significant potential in studies of the comparative biochemistry and clinical chemistry of tartrateinhibitable acid phosphatases.

Abstract

1. By imbibing wheat embryos in media that contain methyl-labelled methionine, it is possible to label both terminal and nonterminal 7-methylguanosine constituents in NaCl-insoluble (2.5 M, 0 degrees C) RNA (iRNA). 2. Most of the 7-[Me-14C]methylguanosine in wheat embryo i[Me-14C]RNA is present in nonterminal positions of polynucleotide chains, probably in ribosomal RNA. 3. By passage through a column of oligo-dT-cellulose, it is possible, to show that most of the 7-[Me-3H]methylguanosine in a 'bound' fraction of i[Me-3]RNA from imbibing wheat embryos is present in terminal 'cap' structures, probably in messenger RNA. 4. Although most of the 7-[Me-3H]methylguanosine in the 'unbound' (to oligo-dT-cellulose) fraction of i[Me-3H]RNA was present in nonterminal positions, there was also a highly significant fraction of 7-[Me-3H]methylguanosine in terminal 'cap' structures. Although it will be a subject of continued investigation, possible reasons why a large fraction of the total 7-[Me-3H]-methylguanosine was present in the 'unbound' fraction, in this present study, are a subject of discussion. 5. Careful analysis failed to reveal the presence of any N6,O2'-di[Me-3H]methyladenosine in the 'unbound' fraction of i[Me-3H]RNA. 6. Factors that might influence the binding of 'cap' oligonucleotides to DEAE-cellulose are the subject of a brief discussion.

Abstract

A simple, rapid and efficient procedure is presented for the purification of human prostatic acid phosphatase (orthophosphoric-monoester phosphohydrolase (acid optimum), EC 3.1.3.2) to homogeneity. The method employs two steps suitable for use with large quantities of material, followed by chromatography on concanavalin A-Sepharose as its sole column step. The procedure also permits the recovery of purified enzyme in higher yields than earlier methods.

Abstract

Treatment of homogenous human prostatic acid phosphatase (orthophosphoric-monoester phosphohydrolase (acid optimum), EC 3.1.3.2) with low concentrations of Woodward's reagent K (N-ethyl-5-phenylisoxazolium-3'-sulfonate) leads to a rapid loss of enzymic activity. The rate of inactivation of the enzyme is reduced in the presence of the competitive inhibitors phosphate and L-(+)-tartrate, but not in the presence of non-inhibitory D-tartrate. Measurement of the ethylamine produced upon hydrolysis of enzyme modified in the presence of D- and of L-tartrate permitted the quantitative estimation of the number of carboxylic acid residues at the active site. The data indicate that two carboxyl groups per (dimeric) enzyme molecule are essential for catalytic activity. It is proposed that one function of the active site carboxyl group may be to protonate the leaving alcohol or phenol portion of the phosphomonoester substrate during the formation of the covalent phosphoenzyme intermediate.

Abstract

The stereochemical course of the phospho transfer catalyzed by homogeneous human prostatic acid phosphatase was investigated using 31P nuclear magnetic resonance spectroscopy. Transphosphorylation from phenyl-(R)-[15O, 17O, 18O]phosphate to (S)-propane-1,2-diol occurs with overall retention of configuration at phosphorus. This stereochemical result is consistent with the interpretation that the hydrolysis of substrates by this enzyme proceeds by way of a covalent phosphoenzyme intermediate. Conditions for optimizing phospho transfer by this and related acid phosphatases have also been explored.
