A photogeologic and physical modeling study indicates that Hebes Chasma, Mars, formed by collapse of the megaregolith. Local heating facilitated drainage of ~105 km3 of brines and entrained particulates through fractures in the chasma fl oor and into a regional aquifer. A megaregolith rich in salts and water is implied by massive, low-gradient allochthonous fl ows that terminate in deep pits an...
For periods up to 21 days human bone marrow was cultured in control conditions that favor the proliferation and differentiation of osteoblastic cells. The effect of AISI 316L corrosion products and the corresponding major separate metal ions (Fe, Cr, and Ni) were studied in three different phases of the culture period in order to investigate the effects of metal ions in cell populations represe...
The Alpine Haselgebirge Formation represents an Upper Permian to Lower Triassic evaporitic rift succession of the Northern Calcareous Alps (Eastern Alps). Although the rocksalt body deposits are highly tectonised, consisting mainly of protocataclasites and mylonites of halite and mudrock, the early diagenetic history can be established from non-tectonised mudrock bodies: Cm-sized euhedral halit...
Massive deposits of rock salt are mined in the Salt Range area Pakistan. The main export products include lamps, blocks, and tiles, while local consumption includes chemical industry domestic use. profitable production for value addition depends on quality, size, shape block. processing is easier when very few cracks present blocks. current mining practice involves drilling blasting, which intr...
Anjirch Pb-Zn deposits are located 55 km wesl of Esrahan. These deposits belong 10 a part of a large sedimenta ry basin containing lead ttnd zinc metal epieiences, in Sanand aj - Si rjan zone. This basin contains Lower CretO:tceous (Albian - Abtian) sedimentary sequences. The Anjireh deposits are typical of Mississippi-valley type stratttbound lead-zinc deposits. The principal metal miner...
The adipocyte-rich microenvironment forms a niche for ovarian cancer metastasis, but the mechanisms driving this process are incompletely understood. Here we show that salt-inducible kinase 2 (SIK2) is overexpressed in adipocyte-rich metastatic deposits compared with ovarian primary lesions. Overexpression of SIK2 in ovarian cancer cells promotes abdominal metastasis while SIK2 depletion preven...
Amyloid β (Aβ) fibrillar deposits in the brain are a hallmark of Alzheimer disease (AD). Curcumin, a common ingredient of Asian spices, is known to disrupt Aβ fibril formation and to reduce AD pathology in mouse models. Understanding the structural changes induced by curcumin can potentially lead to AD pharmaceutical agents with inherent bio-compatibility. Here, we use solid-state NMR spectrosc...
The growth of vertically laminated calcium-sulphate wedges in the Atacama Desert is assumed to be driven by interaction moisture supply and salt dynamics subsurface. Geochronological data these wedge laminations yet sparse but indispensable resolve wedge-growth phases episodes use deposits as a palaeoclimate archive hyperarid environment. Our pilot study presents first approach dating from usin...
