A prospective analysis of trash, brush, and grass burning behaviors.

Burn injuries sustained during residential trash, brush, and grass burning cause significant morbidity and mortality in rural areas. To further prevention efforts, we surveyed individuals who incurred injuries from residential burning. Thirty-six individuals injured while burning trash, brush, or grass from June 2003 through September 2005 were asked to respond to a self-administered written survey. Injury related questions revealed that the majority of those injured were burning brush (21 of 35, 60.0%) in an open space (19 of 35, 54.2%) with the addition of accelerants (27 of 36, 75%). Survey questions regarding usual burning practices revealed almost two-thirds burned either brush or a mixture of brush and trash (23 of 36, 63.9%). Eighty percent of those who were injured desired to change their behavior (25 of 35, 80%). Approximately two-thirds would consider asking for help with burning if it were provided (22 of 34, 64.7%). Our survey shows that acceptable alternatives to burning varied depending on the material that was burned. As the majority of respondents usually burned brush or a mixture of brush and trash, an acceptable trash removal system should also include brush pickup. As residential burning continues presently, injury prevention efforts are essential and should focus on the misuse of gasoline, uniform safety standards for gasoline cans, and dissemination of safe burning practices.     

Bovine cartilage, coenzyme Q10, and wheat grass therapy for primary peritoneal cancer

The accepted postsurgical first-line therapy for primary peritoneal cancer has been a regime of chemotherapy. This paper reports the case of an 89-year-old female who refused chemotherapy but accepted a nutritional alternative. Results after more than 4 years of the nutritional regime have been encouraging with regards to objective and subjective measures.     

IgE, IgG and patient-self tests during slow hyposensitization to grass pollen.

Twenty-two patients with severe hay fever unrelieved by antihistamines in previous years were slowly hyposensitized with alum-precipitated pyridine grass pollen extracts. Their responses were objectively assessed as very good (55%), good (18%) or improved (23%). Two mechanisms were detected: (i) an increase in serum blocking activity in 59% and (ii) the prevention in 59% of the serum IgE elevation expected in the pollen season.     

Species specific grass pollen sensitivity: diagnosis and treatment with single grass species Allpyral vaccines.

Skin test titrations and nasal provocation tests in sixty patients with hay fever showed specific reactions to extracts of individual grass species. There was, however, no correlation between skin and nasal sensitivity. Repeat testing after treatment with Allpyral vaccines consisting of only the grass species to which the nasal reaction was most severe, or only one of several pollens to which reactions were equally severe, showed marked diminution of skin and nasal sensitivity not only to the single pollen used for immuno-therapy but to all five common pollens used in the Allpyral grass mix. Clinical results seemed much improved as compared with results in the same year for Allpyral five grass mix vaccines, especially in the case of patients treated with Timothy, rye, or cocksfoot. It was concluded that these three grassees were to be preferred for treatment in England, and that these grasses contain common allergens.     

Genome segment S8 of grass carp hemorrhage virus encodes a virion protein.

The complete nucleotide sequence of the genome segment S8 of grass carp hemorrhage virus (GCHV) was determined from cDNA corresponding to the viral genomic RNA. It is 1,287 nucleotides in length and contains a large open reading frame that could encode a protein of 409 amino acids with a predicted molecular mass of 44 kD. The S8 was expressed using the pET fusion protein vector and detected by Western blotting analysis using the chicken egg IgY against intact GCHV particles, indicating that S8 encodes a virion protein. Amino acid sequence comparisons revealed that the protein encoded by S8 is closely related to protein sigma2 of mammalian reovirus, suggesting that the deduced protein of S8 is an inner capsid protein.     

Evaluation of a compliance device in a subgroup of adult patients receiving specific immunotherapy with grass allergen tablets (GRAZAX®) in a randomized,open-label,controlled study: An a priori subgroup analysis

Objectives: This a priori subgroup analysis was conducted to assess patients' experience with a compliance device for the administration of sublingual specific immunotherapy for grass pollen-induced rhinoconjunctivitis.Methods: The present paper reports the results of a subgroup analysis of a multicenter, randomized, controlled, open-label European study in which adults with grass pollen-induced rhinoconjunctivitis received once-daily treatment with grass allergen tablets with or without a device to aid compliance. Treatment was given ~6 to 12 weeks before the grass pollen season, during the season (~8–10 weeks), and for up to 2 weeks after the end of the season. In the subgroup analysis, patients from Germany and the Netherlands who had been randomized to receive the compliance device were asked to complete a brief questionnaire at the final study visit. The questionnaire included 6 items concerning patients' use of the device and whether it helped them remember to take their tablets.Results: Of the 91 patients from Germany and the Netherlands who were randomized to use the compliance device along with grass allergen tablets, 71 returned the questionnaire. Among responders, 58 of 71 (82%) reported using the device sometimes or always, 50 of 63 (79%) found the device easy to use, 32 of 69 (46%) found that the device made it easier to remember to take tablets, and 43 of 71 (61%) indicated that they would consider using the device again.Conclusion: Most patients in this subgroup analysis used the compliance device as a medication reminder and rated it easy to use.     

A comparative study of an aqueous grass pollen extract and glutaraldehyde-treated grass pollen-tyrosine adsorbate in the treatment of pollenosis.

Hyposensitization therapy gave a subjective improvement in 84% of grass pollen-sensitive patients receiving an eighteen dose course of aqueous pollen extract (SDV) and in 69% of patients receiving a three dose course of glutaraldehyde-treated pollentyrosine adsorbate (Pollinex). Systemic reactions to treatment were considerably more frequent with the aqueous course, but virtually absent with the short adsorbate course, which seems therefore more convenient for the patient. The SDV treatment induced a more pronounced IgG antibody response both in patients and in guinea-pigs receiving the clinical dosage schedule. The Pollinex treatment showed a tendency to enhance the IgE antibody response in new patients.     

Superparamagnetic iron oxide nanoparticles conjugated to a grass pollen allergen and an optical probe

In this study we report the development of a bioconjugate between superparamagnetic iron oxide nanoparticles and Phl p5a (one of the major allergens from grass pollen). The bioconjugate also contains an optical probe (Alexa647) conjugated to the nanoparticle via biotin–streptavidin association. We show that this conjugate has a range of features that makes it a very promising candidate to image the localization of this allergen in vivo: (a) upon conjugation to the iron oxide nanoparticles, the allergen retains its ability to interact with IgE antibodies; (b) the magnetic properties of the iron oxide core of this bioconjugate are suitable for MR imaging; and (c) Alexa647 fluorophore retains its emission properties once attached to the iron oxide nanoparticles, yielding a dual modality MRI‐optical probe.

Plasma-fixated nitrogen as fertilizer for turf grass

We investigated the use of plasma-fixated nitrogen, which produces nitrates (NO₃⁻) in water, as a possible nitrogen fertilizer for recreational turf such as rye grass and bent grass. Experiments were carried out to study the effects of nitrate concentration on growth, the further effects of adding phosphorous (P) and potassium (K) to the plasma nitrated solution to make an N–P–K complete fertilizer, and to compare the efficacy of plasma-fixated nitrogen to sodium nitrate (NaNO₃) and potassium nitrate (KNO₃). The results indicate that the growth and biomass of the plants were strongly dependent on the concentration of the plasma-fixated nitrogen. Adding P–K to the plasma-fixated nitrogen improved grass growth. Grass that was supplied plasma-fixated nitrogen had improved growth compared to those supplied with equal amounts of NaNO₃ and KNO₃. This work highlights the potential use of plasma-fixated nitrogen as a fertilizer source for commonly used turf grass.

Plasma-fixated nitrogen is a sustainably produced nitrogen fertilizer with applications in recreational turf grass such as rye grass and bent grass.     

Sustainable and eco-friendly dyeing of traditional grass cloth with a reactive dye in palm oil medium

Traditional grass cloth has been used in China for a long time for the manufacturing of various household furnishing textiles and ladieswear. However, traditionally the grass cloth is dyed with reactive dyes in an aqueous medium, but the dyeing process is not sustainable because of high energy and water usage and the production of coloured effluent. In this work, the possibility of palm oil/water dual-phase dyeing of traditional grass cloth with a reactive dye, C.I. Reactive Blue 194 (Reactive Blue 194), was explored. The grass cloth soaked in an alkaline solution with 80–140% pick-up was dyed in a palm oil dyebath containing dye powder dispersed in a palm oil medium. The initial study confirmed that the pre-treatment of the fabric with an alkaline solution with 140% pick-up was beneficial for the uniform distribution of the dye in the fibres. The dyeing process parameters (e.g., fixation temperature, solution pH, and fixation time) for the grass cloth dyeing with the Reactive Blue 194 were optimised by using the Taguchi method. The pH of the alkali pre-treatment solution was found to be the most influential factor, as confirmed by the analysis of variance in terms of the percentage of contribution (94.41%), which was statistically significant (P < 0.05). The confirmation tests were carried out under optimal settings, and a higher K/S (24.06) was found compared with the initial condition (21.51). X-ray diffraction analysis indicated that the dyeing process did not affect the crystallinity of the grass cloth fibres. Furthermore, the recovery of palm oil from the spent dyebath was around 99%, and up to five times recycling and reuse of palm oil were studied for the dyeing of grass cloth. The colour strength of the grass cloths dyed in the palm oil recycled up to five times was similar to the cloth dyed in fresh palm oil. The results show that palm oil can be used as a dyeing medium for the sustainable dyeing of grass cloth with effluent reduction, which can be extended to the dyeing of other textile fibres.

Hydrolysis dynamics for batch anaerobic digestion of elephant grass

Elephant grass might be a potential source of fine chemical precursors and bioenergy. In the present study, we investigated the dynamics of hydrolysis of elephant grass. Three models were used to fit the hydrolysis rate constants—flat, spherical, and cylindrical models. The hydrolysis rate constants obtained using the spherical model presented the best fit between the experimental and theoretical values. Furthermore, we determined the secondary reinforcement points and interventions that can be introduced to speed up the hydrolysis process. Our findings will provide information for studies on the hydrolysis of elephant grass and promote its application in the biogas industry as an alternative biofuel.
