We perform magnetohydrodynamic simulations in full general relativity of uniformly rotating stars that are marginally unstable to collapse. These simulations model the direct collapse of supermassive stars (SMSs) to seed black holes that can grow to become the supermassive black holes at the centers of quasars and active galactic nuclei. They also crudely model the collapse of massive Population III stars to black holes, which could power a fraction of distant, long gamma-ray bursts. The initial stellar models we adopt are Γ = 4/3 polytropes initially with a dynamically unimportant dipole magnetic field...

Background: Kidneys as vital organs remove waste material from blood. Additionally, they may also have a role in the electrolyte balance, regulation of blood pressure, and red blood cell genesis. Kidney diseases may be caused by several factors such as ischemia/reperfusion injury, diabetes, and nephrotoxic agents. Oxidative stress and inflammation are involved in the pathogenesis and progression of kidney diseases. Traditionally, natural antioxidants are used for treatment of renal failure in various countries...

Vitamin D has previously been quantified in some plants and algae, particularly in leaves of the Solanaceae family. We measured the vitamin D content of Australian native food plants and Australian-grown edible seaweed. Using liquid chromatography with triple quadrupole mass spectrometry, 13 samples (including leaf, fruit, and seed) were analyzed in duplicate for vitamin D₂, vitamin D₃, 25-hydroxyvitamin D₂, and 25-hydroxyvitamin D₃. Five samples contained vitamin D₂: raw wattleseed ( Acacia victoriae ) (0...

BACKGROUND: Thymoquinone (TQ), the major active compound isolated from black seed oil (Nigella sativa), has been reported to exhibit anti-inflammatory and anticancer abilities. However, the exact molecular mechanism underlying the anticancer effect of TQ is still poorly understood, especially in regard to TQ's effect on endoplasmic reticulum stress-mediated apoptosis. METHODS: The cytotoxicity of TQ on T24 and 253J bladder cancer cells was analyzed by MTT assay, colony formation assay and Annexin V-FITC/PI staining, while SV-HUC-1, the SV-40 immortalized human uroepithelial cell line, was used as a normal control...

In this study we elucidate antioxidative properties of the mushroom Ganoderma applanatum (Pers.) Pat. enhanced by submerged culture with para-hydroxyphenolic compounds and tea leaf extracts. The tea extract has been shown to increase to different extents the antioxidative efficiency of para-substituted phenolics, with the most profound effect for 2-(4-hydroxyphenyl)ethane-1-ol (tyrosol). Within the range of physiological concentrations, the symbatic correlation of the antioxidative action of the fungal samples with the volume of tea extract in the submerged culture medium was observed...

The distribution of Alopecurus myosuroides (black-grass) in fields is patchy. The locations of these patches can be influenced by the environment. This presents an opportunity for precision management through patch spraying. We surveyed five fields on various types of soil using a nested sampling design and recorded both A. myosuroides seedlings in autumn and seed heads in summer. We also measured soil properties at those sampling locations. We found that the patches of seed heads within a field were smaller than the seedling patches, suggesting that techniques for patch spraying based on maps of heads in the previous season could be inherently risky...

A hitherto unknown low molecular weight form of α-galactosidase (VM-αGal) from germinating black gram (Vigna mungo) seeds was purified to homogeneity (432 U/mg specific activity, 1542-fold purification) using ion-exchange (DEAE-cellulose, CM-sepharose) and affinity (Con-A Sepharose 4B) chromatography. VM-αGal appeared as a single band ~ 45 kDa on SDS-PAGE and showed optimal activity at pH 5 and 55 °C. Hg2+ and SDS completely inhibited VM-αGal activity. The Km, Vmax and catalytic efficiency (kcat /Km ) of VM-αGal for pNPG and raffinose was found to be 0...

Snowshoe hares ( Lepus americanus ) maintain seasonal camouflage by molting to a white winter coat, but some hares remain brown during the winter in regions with low snow cover. We show that cis-regulatory variation controlling seasonal expression of the Agouti gene underlies this adaptive winter camouflage polymorphism. Genetic variation at Agouti clustered by winter coat color across multiple hare and jackrabbit species, revealing a history of recurrent interspecific gene flow. Brown winter coats in snowshoe hares likely originated from an introgressed black-tailed jackrabbit allele that has swept to high frequency in mild winter environments...
