Idealised versus tainted femininity: discourses of the menstrual experience in Australian magazines that target young women

Proposed mechanisms of action for ascorbic acid (ascorbate, vitamin C) in the prevention and treatment of cancer include enhancement of the immune system, stimulation of collagen formation necessary for "walling off" tumors, inhibition of hyaluronidase which keeps the ground substance around the tumor intact and prevents metastasis, prevention of oncogenic viruses, correction of an ascorbate deficiency often seen in cancer patients, expedition of wound healing after cancer surgery, enhancement of the effect of certain chemotherapy drugs, reduction of the toxicity of other chemotherapeutic agents such as Adriamycin, prevention of free radical damage, and neutralization of carcinogenic substances. Scottish as well as Japanese studies have pointed to the potential benefit of high dose vitamin C for the treatment of "terminal" cancer. Mayo Clinic studies, however, have contradicted the Scottish and Japanese findings, resulting in accusations of methodological flaws from both sides. Numerous epidemiological studies have pointed to the importance of dietary and supplemental ascorbate in the prevention of various types of cancer including bladder, breast, cervical, colorectal, esophageal, lung, pancreatic, prostate, salivary gland, stomach, leukemia, and non-Hodgkin's lymphoma.     

废锂电池酸浸液非萃取除杂研究

主要研究了废锂电池酸浸液杂质除杂原理,采取“两段酸浸—中和除Fe、Al—絮凝除F—深度除杂”非萃取除杂工艺。在除杂过程中,由于酸浸液含高浓度Ni、Co、Mn离子,中和剂的种类和浓度将影响Ni、Co、Mn的损失率。通过工艺控制及中和剂调试,选择10%CaCO₃作为除Fe、Al、F中和剂,Fe、Al、Cu、F含量可分别从0.20、9.76、0.58、1.66 g/L降至0.01、0.02、0.01、29.86 mg/L,达到三元前驱体溶液杂质标准要求。此时,Ni、Co、Mn的损失率分别仅为0.96%、0.04%、0.01%,均在接受范围之内。     

Factors related to thickness of melanoma. Multifactorial analysis off variables correlated with thickness of superficial spreading malignant melanoma in man

Computer analyses to identify correlations between thickness of primary superficial spreading malignant melanoma and eighteen variables previously reported to be related to prognosis were performed on a series of malignant melanomas. The variables that showed statistically significant (less than or equal to 0.05) direct relationships to thickness were level (Clark), elevation of lesion, age of patient, least and greatest diameters of lesion, history of bleeding, ulceration, clinical and histologic stage, anatomic location, pedunculation, and satellitosis. The variables that did not correlate with thickness were clinical diagnosis of regional lymphadenopathy, in-transit metastasis, duration of lesion, sex, history of a previous malignant melanoma, and history of a pre-existing lesion at the site of the development of melanoma. Multiple regression analysis of the factors that showed statistically significant correlation with thickness of the primary lesion revealed a subset of six dominant variables that were most predictive of thickness, namely, level, elevation, largest diameter of lesion, ulceration, histologic stage, and age of the patient.     

BASETY: Extension et typicalité des exemplaires pour 21 catégories d'objets.

Basety is a French semantic database of exemplars of 21 categories of objects, with a typicality index associated with each exemplar. These 21 semantic categories are animals, trees, weapons, buildings, flowers, fruits, insects, instruments of music, games, toys, vegetables, mammals, furnitures, birds, tools, fish, occupation, containers, sports, vehicles, and clothes. Basety was made up with two groups of 18-to-30 years old French participants, a first group of three subgroups of 100 participants producing exemplars for 7 × 3 categories while a second group of 80 participants evaluating membership of these exemplars. Typicality was computed as the number of occurrences of the exemplar within the set of the five exemplars participants were first producing. Cronbach's coefficient of reliability indicates an internally consistent scale and number of exemplars is correlated with membership ratings: the more the participants of the first group produced exemplars, the more the participants of the second group agreed on the degree of membership of these exemplars. BASETY appears to be a consistant and valid database for French semantic research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The symbolism of salt in paintings

Many artists have used the symbol of salt in both religious and profane works, yet very few studies have explored the symbolism of salt as used in works of art. In this study, Panofsky's method has been adopted to evaluate works of art through an organic process articulated into three stages: (1) pre-iconographic, (2) iconographic and (3) iconological. The method was used for (a) religious paintings of the Old and New Testaments and (b) mythological and profane themes. Various salt-cellars were also studied. In particular, the paper examines the following themes: Isaac blessing Jacob, the return of Esau, Samuel consecrating David, the Last Supper, the suppers at Emmaus and at the house of Simon, the birth of St. John the Baptist, the Baptism of Constantine, the prodigal son, Bacchus-Apollo, the nuptial banquet of Love and Psyche, the death of the Cavalier of Celano, the king drinks, the landlord's visit, 'Phitopolis faisant servir des mets en or au roi Pithès', certain still life paintings and various salt-cellars including those of Cellini and Giulio Romano. The paper discusses the works of many artists including Raphael, Leonardo and his school (Boltraffio, Giampietrino, d'Oggiono, Solario), Hendricksz, Corenzio, Jean-Baptiste and Philippe de Champaigne, Damaskinos, Tintoretto, Titian, Romanino, Rubens, Bellini, Bloemaert, Veronese, Sustris, Just of Ghent, Jan Van Hemessen, Poussin, Loir, Giotto, Jordaens, Brueghel and Mimmo Paladino with his enchanted mountain. From the data examined it emerged that salt is a primary iconological presence in various works of art.     

Search for lead structures to develop new allosteric modulators of muscarinic receptors

Various compounds are known to allosterically modulate the binding of ligands to muscarinic receptors. Most of these compounds have another predominant pharmacological action. Identification of the potent representatives should be useful for the development of allosteric modulators that are specific and highly active. For various reasons, a direct comparison of allosteric potencies on the basis of literature data is difficult. Therefore, a series of compounds was compared with regard to the allosteric delay of the dissociation of N-[3H]methylscopolamine from porcine heart M2 receptors under the following assay conditions: "Na,K,Pi buffer", 4 mM Na2HPO4, 1 mM KH2PO4, pH 7.4, 23 degrees C; "Mg,Tris,Cl,Pi buffer', 50 mM Tris-HCl, 3 mM MgHPO4,pH 7.3, 37 degrees C. Generally, the allosteric potency of the compounds was higher in the Na,K,Pi buffer, compared with the Mg,Tris,Cl,Pi buffer. However, the extent of the potency shift differed, ranging from approximately 2-fold for tacrine to approximately 100-fold for gallamine. The concentration retarding radioligand dissociation to half of the control rate (EC50) served as a measure of allosteric potency. Under both assay conditions, alcuronium was the most potent compound (EC50,Na,K,Pi = 4 nM and EC50,Mg,Tris,Cl,Pi = 55 nM), followed by alkane-bisammonium and bispyridinium compounds containing phthalimido moieties. Gallamine showed intermediate potency (EC50 values of 180 nM and 16,000 nM in Na,K,Pi buffer and Mg,Tris,Cl,Pi buffer, respectively). Obidoxime and hexamethonium, both known to antagonize allosteric actions, revealed submaximal efficacy and low potency (EC50,Na,K,Pi of approximately 100,000 nM). The relevance of these results, regarding the identification of lead structures for the development of new allosteric modulators, is discussed.

Reactions of non pregnant and and of cattle at different stages of pregnancy from the Holstein Friesian breed (HF) and from the old type German black and white breed (DSB) exposed to transport stress: variation and individual reaction patterns of hormone metabolic and hematologic variables

Breeding animal transports between parts of our institute were used assessing effects of age of animals, of breed, of their functional state and of individual specificity of reaction patterns using peripheral venous blood samples. Increased mean values of Hb, Hk, body temperature, total protein, albumin, FT4, T4, FT3, T3, cortisol, adrenaline and decreased ones of body weight, Pa, Fe, noradrenaline were found after transport stress. Comparing age matched groups of DSB and HF breed higher concentrations of total protein, creatinine, lactate, cortisol, FT4, T3 and FT3 and lower ones of albumin, blood urea and Fe could be observed in animals of DSB breed before and after transport. Strong correlations existed on 14 variables within animals before and after transport stress meaning there could be individual specificity of some blood parameters.     

THE FORMATION OF URANIUM AND OF BERYLLIUM ALLOYS BY THE SOLID-STATE SINTERING OF MIXED ELEMENTAL POWDERS

Abstract

Large volume expansions accompany the formation of binary alloys of beryllium with uranium, thorium, iron, copper, zirconium, titanium, and vanadium, and of uranium with aluminium, during the sintering of the mixed, cold-compacted elemental powders. No expansion was detected during the sintering of binary mixtures of beryllium with aluminium, silicon, and magnesium, or mixtures of uranium with zirconium, molybdenum, iron, nickel, manganese, and chromium.

When it occurs, expansion is anisotropic, being greatest in the direction of compacting; the degree of anisotropy varies with the constituents and the composition of the alloys. In systems undergoing expansion, the volume expansion/composition graphs exhibit maxima. For a given system the magnitude of the maximum is a function of the shape of compact, the particle size of the powders, and the sintering time and temperature; the composition at which the maximum occurs is sensibly unaffected by these latter variables.

These experimental observations, together with those of other investigators, can be satisfactorily interpreted on the hypothesis that volume expansion is due to the formation of diffusional porosity during sintering.     

Prevalence of diabetic ocular complications and systemic factors

The prevalence of diabetic ocular complications and the correlation between diabetic retinopathy and systemic factors were examined in 2,300 cases (4,600 eyes) with non-insulin-dependent diabetes mellitus. The prevalence of cataract was 66.7%, of retinopathy 37.0%, of refractive and accommodative change 6.2%, of glaucoma 1.9% (rubeotic glaucoma was 1.0%), of rubeosis iridis 1.5%, of iridocyclitis 0.8%, of extraocular muscle palsy 0.2%, and of ischemic optic neuropathy 0.1%. Duration of diabetes mellitus, HbA1C value, methods of diabetic control, age, diabetic nephropathy, diabetic neuropathy, hypertension, systolic blood pressure, diastolic blood pressure, and arteriosclerosis obliterans were related with diabetic retinopathy. We suggest that the management of diabetic patients needs sufficient attention in the cases with oral administration of medication, insulin therapy, and diabetic nephropathy.
