Background:Chemotherapy-induced peripheral neuropathy (CIPN) is a serious therapy-limiting side effect of commonly used anticancer drugs. Previous studies suggest that lipids may play a role in CIPN. Therefore, the present study aimed to identify the particular types of lipids that are regulated as a consequence of paclitaxel administration and may be associated with the occurrence of post-therapeutic neuropathy.Methods:High-resolution mass spectrometry lipidomics was applied to quantify d=255 different lipid mediators in the blood of n=31 patients drawn before and after paclitaxel therapy for breast cancer treatment. A variety of supervised statistical and machine-learning methods was applied to identify lipids that were regulated during paclitaxel therapy or differed among patients with and without post-therapeutic neuropathy.Results:Twenty-seven lipids were identified that carried relevant information to train machine learning algorithms to identify, in new cases, whether a blood sample was drawn before or after paclitaxel therapy with a median balanced accuracy of up to 90%. One of the top hits, sphinganine-1-phosphate (SA1P), was found to induce calcium transients in sensory neurons via the transient receptor potential vanilloid 1 (TRPV1) channel and sphingosine-1-phosphate receptors.SA1P also showed different blood concentrations between patients with and without neuropathy.Conclusions:Present findings suggest a role for sphinganine-1-phosphate in paclitaxel-induced biological changes associated with neuropathic side effects. The identified SA1P, through its receptors, may provide a potential drug target for co-therapy with paclitaxel to reduce one of its major and therapy-limiting side effects.Funding:This work was supported by the Deutsche Forschungsgemeinschaft (German Research Foundation, DFG, Grants SFB1039 A09 and Z01) and by the Fraunhofer Foundation Project: Neuropathic Pain as well as the Fraunhofer Cluster of Excellence for Immune-Mediated Diseases (CIMD).

Published: March 2024

Experiments were conducted to evaluate NPK fertilizer and wood-ash application on flowering, cherelle performance and pod yield of cacao (Theobobroma cacao L). Treatments includes NPK 15.15.15; NPK + wood-ash; sole wood-ash and control with five cacao varieties (TC1, TC2, TC3, TC4, and TC6) in a 4x5 factorial experiment with three replications. Data were measured on flowering, cherelle formation, and pod development. From the results, flowering, cherelle formation and pod development were significantly enhanced by application of NPK, sole wood-ash and their combinations over control plots. Application of wood-ash alone significantly enhanced flowering, cherelle formation and pod development in both seasons over other fertilizer treatments. However, cherelle wilt under sole application of wood-ash was significantly higher compared to sole NPK and NPK + wood-ash combinations. Interaction effects of fertilizer and cacao varieties had significant positive effects on flower development and reduced cherelle wilt in both light and main crop seasons. Interactions of wood-ash and cacao varieties were found to significantly enhanced cherelle formation and pod development. The study concludes that NPK, NPK + wood-ash and sole wood-ash treatments significantly enhanced flowering, cherelle formation and pod development in cacao over the control. Also, cherelle with rate drop significantly with integration of NPK+wood-ash

Published: March 2024

The conventional method of rose propagation involves budding on one year old field established rootstock plants. For multiplication of plants, cutting is the simplest way of propagation of desirable rose varieties. There are relatively few varieties that develop roots, so exogenous application of growth promoters is essential. In order to study the effects of different concentrations of IBA (0, 500, 1000 and 1500 ppm) on rooting of different varieties (English Holiday, Eiffel Tower, Don Don, Confetti and Iceberg) of rose, during planting times viz., February, July, October and December, It was found that 500 ppm IBA resulted in maximum number of roots (15.66), number of leaves (22.33), the percentage of survival (50%), shoot length (13.23 cm), fresh weight of roots (4.80 g) and stem (5.93 g), dry weight of roots (4.36 g) and stem (4.33 g) and took minimum days (13.00) for leaf bud initiation, whereas,the maximum root length (7.80 cm) was found in 1000 ppm IBA in Eiffel Tower variety and control treatment had the lowest effect on the different traits of rooting in rose cutting . Among different varieties, Eiffel Tower was found to be best in terms of different traits, whereas English Holiday and Confetti didn't respond to any of the planting times and treatments. Cuttings planted in February showed the highest effect on their evaluated traits with a significant difference with those planted in July and October, whereas in December planting time, zero survival rates was observed.

Introduction: Intimate partner violence (IPV) is an aberrant behavior that occurs within an intimate relationship resulting in physical, sexual, and psychological harm to a partner. It transcends all strata of the society including socio-cultural groups, families and the community as a whole. Amongst people diagnosed with the Human Immuno-deficiency Virus (HIV), IPV could have adverse health consequences and this could have serious implications for disease progression, transmission and control. This study was therefore aimed at assessing the knowledge, prevalence and forms of IPV against people with HIV/AIDS in Sokoto metropolis, Nigeria.
Methods: A cross-sectional descriptive study design was used to recruit a total of 330 respondents which comprised adult male and female HIV/AIDS patients receiving comprehensive health care services in selected health facilities in Sokoto metropolis. Data on knowledge, prevalence and forms of IPV was elicited using a set of semi-structured interviewer- administered questionnaire downloaded into Open Data Kit (ODK). Data collected was entered into and analyzed using SPSS statistical software version 25 with level of statistical significance set at p<0.05.
Results: More than two-thirds, 259 (78.5%) of the respondents were diagnosed with HIV within the last one to ten years with almost all, 323(97.9%) having good knowledge of IPV. Only 28 (8.5%) of the respondents experienced at least one form of IPV with more females (9.5%) compared to 4.5% of males experiencing IPV. The various forms of IPV experienced by the respondents included sexual (4.2%), physical (6.7%) and psychological (8.5%).
Conclusion: Although almost all the respondents were knowledgeable about IPV, only a few of them experienced one form of IPV or the other. This has wider public health implications for interventions and underscores the need to initiate IPV screening among people living with HIV, improved awareness of IPV and supportive in care services and counseling aimed at better clinical outcomes amongst PLWHA.
Polymer–polymer mutual diffusion via rheology of coextruded multilayers
Authors: Zhao Rui , Macosko Christopher W. 
Published: February 2007

AbstractThe mutual diffusion coefficient of a pair of polyethylenes using coextruded multilayers has been measured. Two polyethylenes with different molecular weight were coextruded in 32 alternating layers in about 45 s of contact time. When the multilayer sample was remelted in a parallel plate rheometer, its apparent viscosity increased due to interdiffusion. By following the kinetics of the apparent viscosity increase, the mutual diffusion coefficient was measured. The theory of Kramer et al. (Polymer. 1984; 25:473‐480) was used to describe the mutual diffusion coefficient as a function of the chain mobility parameter, molecular weight, and concentration. The finite element method was used to solve the nonlinear interdiffusion problem to give a concentration profile in these multilayers. By fitting the apparent viscosity of the sample vs. time, the chain mobility parameter was found to be 4.5 × 1011 m/N s, and the range of the mutual diffusion coefficient for these two PE's was 10−12–10−14 m2/s at 200°C (depending on concentration). This is an easy and rapid method to measure the mutual diffusion coefficient for miscible polymers with different melt viscosities. © 2007 American Institute of Chemical Engineers AIChE J, 2007

Published: February 2007

AbstractThe porous structure was prepared with polyether ether ketone (PEEK) and polyphenylene sulfide (PPS), which had excellent solvent resistance and thermal resistance as the mixed polymers, and diphenyl ketone as the diluent. The possibility of forming porous structure and the control of porous structure were investigated in the blended system. The effecting factors including the different weight ratios of PEEK/PPS and the total concentration of polymers on the porous structure are discussed, and the two‐step phase separation process brings forward the formation of membrane in this system. © 2007 Wiley Periodicals, Inc.

Published: February 2007

AbstractVulcanizates from blends of natural rubber and thioglycolic acid modified, epoxidized, low‐molecular‐weight natural rubber filled with mixtures of carbon black and carbonized rubber seed shell, with semiefficient sulfur vulcanization recipes, were critically investigated and characterized. The investigated properties were the processing and rheological properties (the cure rate, cure time, scorch time, total oscillating disc rheometry torque, and Mooney viscosity), physicomechanical and chemical properties, solvent resistance, solubility, and swelling properties. On the basis of the investigated properties, it was observed that the carbonized rubber seed shell acted as a plasticizer and not as a reinforcing filler such as carbon black. The replacement of carbon black with up to 20% carbonized rubber seed shell produced vulcanizates having processing advantages in time gain and energy consumption, with their physical, chemical, and mechanical properties around the acceptable level for natural rubber compounds but lower than the properties obtained for a 100% carbon black filled vulcanizate. © 2007 Wiley Periodicals, Inc.

Published: February 2007

AbstractGlutaraldehyde‐crosslinked alginate gel containing chitosan (AGCC) used for the removal of Hg2+ ions from aqueous solutions. Three bead sizes were obtained and performed to study the uptake equilibrium and kinetics of Hg2+ by AGCC (ca. an hour). The adsorption capacity was found to be independent of adsorbent particle size indicating that sorption occurs in the whole AGCC bead. A high initial rate of Hg2+ uptake was followed by a slower uptake rate suggesting intraparticle diffusion as the rate‐limiting step. The rate of Hg2+ uptake increases with decreasing AGCC bead size. AGCC also enhanced the rate and the capacity of Hg2+ adsorption. The maximum Hg2+ adsorption capacity of AGCC was found 667 mg/g, which is over 20 times higher than that of alginate bead. Our results reveal the well‐distributed chitosan powders in the alginate gel bead and Hg2+ ions can reach inside the chitosan bead. It indicates the feasibility of using AGCC as metal adsorbent at low pH values, and allows the regeneration of adsorbent. Hg2+ ions adsorbed on AGCC bead were desorbed effectively about 95% by H2SO4 at the third cycle. The use of AGCC for the removal of Hg2+ ions from the waste streams appears to be promising. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007

Published: February 2007

AbstractAmphiphilic graft copolymers consisting of poly(phthalazinone ether sulfone ketone) (PPESK) backbones and poly(ethylene glycol) (PEG) side chains were synthesized via reaction of chloromethylated PPESK (CMPPESK) with a sodium alkoxide of methoxyl PEG (PEG‐ ONa). The reactive precursor, CMPPESK, was prepared by the chloromethylation of PPESK with chloromethylether (CME) using concentrated H2SO4 as reaction medium. FTIR spectroscopy, 1H‐NMR and Solid‐state 13C CP‐MAS NMR analysis confirmed the covalent linking of PEG with PPESK backbones. The PEG content in the graft copolymers from 1H‐NMR analysis varied from 21.0 to 37.2 wt %, which was approximately in agreement with that calculated from TGA tests. The graft products have good solubility in many aprotic polar solvents and can be slightly swelled by water and ethanol, but water insoluble. Contact angle measurements revealed that the hydrophilicity of PPESK was significantly improved by the introduction of PEG graft chains, indicating the graft copolymer is a potential hydrophilic additive for PPESK membranes. © 2007 Wiley Periodicals, Inc.

Published: February 2007

AbstractA polymer electrode in the form of a thin film was prepared by electrochemical copolymerization of 3‐methylthiophene and thiophene‐3‐acetic acid. Glucose oxidase (GOx) was immobilized by covalent binding to the carboxyl groups on the electrode, and the GOx‐immobilized electrode (GOx‐electrode) was used as an anode in a glucose fuel cell. It was demonstrated by cyclic voltametry that in the presence of p‐benzoquinone (BQ), which was adopted as an electron mediator, the GOx‐electrode generated a significant glucose‐oxidation current depending on the concentrations of both glucose and BQ. A large surface area of the GOx‐electrode was considered to afford effective environment for the enzyme reaction and electron transfer. The fuel cell using the GOx‐electrode as an anode gave a power output of 42 μW/cm2‐anode at 30°C, when its anodic compartment contained 100 mM glucose and 10 mM BQ. The performance of the cell was influenced by the concentrations of glucose and BQ in the anodic compartment. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Chemical modification of poplar wood with foaming polyurethane resins
Authors: Zhenhua Gao , Dong Li 
Published: February 2007

AbstractThis study was devoted to chemically modifying poplar wood with foaming polyurethane (PU) resin, which improved both dimension stability and mechanical property of wood. The controlled tests demonstrated the poplar wood treated with only solvent acetone had decreases of both dimension stability and mechanical property, while the wood modified with solution of polymetric methylenebis(phenylisocyanate) in acetone had an excellent improvement of dimension stability but a little strength loss. Seven foaming PU resins with NCO/OH mole ratio from 12 to 2.5 were used to chemically modified wood, of which the mole ratio 3.0 gave best balance between dimension stability and mechanical property. The 24‐h volumetric swelling coefficient (VSC24 h) and 24‐h water absorption coefficient (WAC24 h) of the modified wood reduced 34.29% and 57.60% and the modulus of rapture and modulus of elasticity improved 39.89% and 37.15%, respectively. The improvements of dimension stability were contributed to that of the hydrophilic hydroxyl groups in wood were blocked by isocyano groups and water movement was hindered by successive cued PU deposit on the surface of vessels. The improvements of mechanical property were owed to the reinforcement of foamed PU on the cell wall and void space of wood. Four morphologic models of foamed PU within wood were discovered by SEM. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007

Published: February 2007

AbstractSemi‐interpenetrating polymer network (semi‐IPN) membranes based on novel sulfonated polyimide (SPI) and poly (ethylene glycol) diacrylate (PEGDA) have been prepared for the fuel cell applications. SPI was synthesized from 1,4,5,8‐naphthalenetetracarboxylic dianhydride, 4,4′‐diaminobiphenyl 2,2′‐disulfonic acid, and 2‐bis [4‐(4‐aminophenoxy) phenyl] hexafluoropropane. PEGDA was polymerized in the presence of SPI to synthesize semi‐IPN membranes of different ionic contents. These membranes were characterized by determining, ion exchange capacity, water uptake, water stability, proton conductivity, and thermal stability. The proton conductivity of the membranes increased with increasing PEGDA content in the order of 10−1 S cm−1 at 90°C. These interpenetrating network membranes showed higher water stability than the pure acid polyimide membrane. This study shows that semi‐IPN SPI membranes based on PEGDA which gives hydrophilic group and structural stability can be available candidates comparable to Nafion® 117 over 70°C. © 2007 Wiley Periodicals, Inc.

Effect of the nature and degree of crosslinking on the Rose Bengal uptake by DVB‐, NNMBA‐, HDODA‐, and TTEGDA‐crosslinked aminopolyacrylamides
Authors: Gigimol M. G. , Mathew Beena 
Published: February 2007

AbstractPolyacrylamides with 2–20 mol % divinyl benzene (DVB), N,N′‐methylene‐bisacrylamide (NNMBA), 1,6‐hexanediol diacrylate (HDODA), and tetraethyleneglycol diacrylate (TTEGDA) crosslinking and without crosslinking were prepared by free radical solution polymerization. Amino functions were incorporated into these polymers by transamidation with excess ethylenediamine. The dye uptake of nonprotonated and protonated aminopolyacrylamides was followed by batch equilibration method towards Rose Bengal (RB), Methyl Orange (MO), Methyl Red (MR), and Methylene Blue (MB). RB uptake by the polyacrylamide‐supported systems is higher than other dyes. Generally the dye uptake by the protonated systems is higher than the nonprotonated systems. To optimize the conditions of dye uptake, the effect of the concentration of RB solutions, temperature, and pH were followed. Kinetic studies showed that the uptake of RB by both nonprotonated and protonated crosslinked aminopolyacrylamides is a phase boundary process followed by three‐dimensional diffusion. The extent of RB uptake by the various systems depends on the nature and degree of crosslinking, and the relative rigidity/flexibility ofthe polyacrylamide support. Thus, the dye uptake followed the order: linear > NNMBA‐ > DVB‐ > TTEGDA‐ > HDODA‐crosslinked system. The dye uptake followed the same trend as the variation of amino capacity with degree of crosslinking in the respective crosslinked system. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007

Published: February 2007

AbstractBio‐inspired gradient materials based on the biodegradable polymer blend are expected to be indispensable to the new approaches for biomedical applications. In this study, multi‐step casting self‐organization on the aluminum surface are used to control the compositional distribution in the blend films of biodegradable chitosan and poly(ethylene oxide). By this way, three kinds of compositional gradient, i.e., pseudobilayer (PG), gradient (G) and semigradient (SG) blend films, along the film thickness were prepared. Their compositional morphologies were evaluated by means of ATR‐FTIR and FTIR mapping measurements. In addition, the moisture absorption behavior and the mechanical properties of the gradient film were characterized with referring their gradient morphologies. It is found that the compositional G films has better mechanical properties compared with those of the PG and SG films in both the dry and wet states. © 2007 Wiley Periodicals, Inc.
