Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

The use of sequential extraction procedure for mercury fractionation study in gold mining tailings: implications for environmental pollution

Journal of Degraded and Mining Lands Management
Artisanal and small-scale gold mining (ASGM) activities still use mercury (Hg) for the amalgamation processing step. These ASGM activities generate tailings as a mining by-product, representing the primary source of environmental Hg contamination.

Gold Extraction to Ferrosilicium, Production of Foam Silicate from Processing Tails of the Olimpiada Mining and Processing Complex Gold Processing Plant (Russia, Krasnoyarsk Territory) [PDF]

, 2019
The paper describes the studies of processing tails of the Olimpiada Mining and Processing Complex with the methods of chemical, mineralogical, electronic microscope, deep reductive melting with division of the melt into a silicate and metal parts. It is demonstrated that 85% of the processing tails consist of the oxides: SiO2, CaO, Al2O3, Fe2O3, H2O ...

Review of trace toxic elements (Pb, Cd, Hg, As, Sb, Bi, Se, Te) and their deportment in gold processing. Part 1: Mineralogy, aqueous chemistry and toxicity [PDF]

, 2011
A literature review on the deportment of trace toxic elements (Pb, Cd, Hg, As, Sb, Bi, Se, and Te) in gold processing by cyanidation is presented which compiles the current knowledge in this area and highlights the gaps.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Study of Mercury and Arsenic Contamination in Gold Processing Tailings from Gunung Botak, Buru Island – Maluku

Indonesian Journal of Chemical Research
Buru Island in Maluku Province is one of the sites of unlicensed gold mining activities (Illegal Gold Mining, IGM), which may lead to environmental pollution due to improper waste management. This study aimed to analyze the concentrations of mercury (Hg)

Detoxification of Cyanide in a Gold Processing Plant Tailings Water Using Calcium and Sodium Hypochlorite [PDF]

Mine Water and the Environment, 2007
In laboratory experiments, cyanide in waste water from the Muteh gold mine in Iran was oxidized by sodium and calcium hypochlorite to cyanate (CNO−), which is 1,000 times less environmentally hazardous than cyanide. Experiments were conducted using waste water containing 270 mg/L cyanide over a pH range of 6–13 and temperatures between 25 and 50°C ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.
