In this work we analyze the pigments used in the decoration of red and yellow motifs present in the portable art of the Parpalló Cave (Gandía, Spain), one of the most important Palaeolithic sites in the Spanish Mediterranean region. Energy dispersive X-ray fluorescence spectrometry (EDXRF) and spectrophotometry in the visible region (CIEL*a*b*color coordinates and spectral reflectance curves) w...

Physiological races of a fungal phytopathogen represent biotypes capable of attacking certain varieties of a susceptible host-species. Attempts to distinguish physiological races by other criteria have not yet been successful. On the other hand, strains of bacterial pathogens may often be identified using bacterial viruses (bacteriophage). Attempts to demonstrate a virus of a true fungus have n...

Atg6 (beclin 1 in mammals) is a core component of the Vps34 complex that is required for autophagy. Beclin 1 (Becn1) functions as a tumor suppressor, and Becn1(+/-) tumors in mice possess elevated cell stress and p62 levels, altered NF-κB signaling and genome instability. The tumor suppressor function of Becn1 has been attributed to its role in autophagy, and the potential functions of Atg6/Bec...

A mixture of 10 wt% CuO-10 wt% Fe2O3 supported on cordierite were prepared by wet impregnation. The as-prepared solids doped with Li2O (0.75-3 mol %) were calcined at 500-900 ºC. The crystalline phase, morphology, and surface area were investigated by XRD, HR-TEM and N2-adsoprtion-desorption. Moreover, their photocatalytic activities of samples calcined at 700°C on the degradation of phenol wer...

Localized deposits of amyloid structures are observed in various pathological conditions. One example of when local amyloidosis occurs is following repeated insulin injections in diabetic patients. The present study aimed to simulate the same condition in mice. To obtain the amyloid structures, regular insulin was incubated at 57°C for 24 h. The subsequently formed amyloid fibrils were analyzed...

we have studied the patients who had a neck mass on presentation in five medical centers of tehran univ. of medical sciences (infectious disease department, ent department, dentistry faculty, cancer institute) during a period of 14 months. sixty patients, 20 women and 40 men, were eligible for our study. all patients underwent clinical and paraclinical work up and finally had histologic diagnos...

The characteristics of the environmental settings of the sea area adjacent to the Changjiang River estuary include complex currents and water masses, the diluted water plume and its redirection, upwelling, front, and nutrients and their sources. The Changjiang River estuary characteristics also include the phytoplankton community, which can affect the growth, migration, assembling, resting and ...

We present the discovery of a red supergiant star that exploded as supernova 2003gd in the nearby spiral galaxy M74. The Hubble Space Telescope (HST) and the Gemini Telescope imaged this galaxy 6 to 9 months before the supernova explosion, and subsequent HST images confirm the positional coincidence of the supernova with a single resolved star that is a red supergiant of 8(+4)(-2) solar masses....

amyloidosis cutis dyschromica (acd) is a rare form of macular amyloidosis characterized by hypo and hyperpigmented macules. here we described a 20 year old girl with diffuse hypo and hyperpigmentation since she was four years old. five other members of her family are also involved. biopsy of hyperpigmented lesions revealed increase of melanin in the basal layer, pigment incontinence and amorpho...

Red music during the Agrarian Revolutionary War was rooted in leadership of Communist Party China and grew up revolutionary struggle. Based on a study background, style effect red this period, paper discusses role propagating theories, mobilizing masses inspiring people founding development bases such as Jinggangshan Mountain, Central Soviet Area Shaanxi-Gansu Border.
