Improving the precision of linear optics measurements based on turn-by-turn beam position monitor data after a pulsed excitation in lepton storage rings

open access: yesPhysical Review Accelerators and Beams, 2017
Beam optics control is of critical importance for machine performance and protection. Nowadays, turn-by-turn (TbT) beam position monitor (BPM) data are increasingly exploited as they allow for fast and simultaneous measurement of various optics ...

Arsenite methyltransferase 3 is required for mitochondrial function and hepatic lipid metabolism

open access: yesThe FEBS Journal, EarlyView.
AS3MT is a protein that helps the body process arsenic, a naturally occurring toxin found in water and soil. We discovered it also helps cells make and use energy properly. Without AS3MT, cells' mitochondria do not work well, leading to fatty liver and reduced activity. Increasing AS3MT in liver cells restores energy and protects against arsenic damage,

A Short-Term Exposure to Tributyltin Blocks Leydig Cell Regeneration in the Adult Rat Testis

open access: yesFrontiers in Pharmacology, 2017
Background: Tributyltin (TBT) is widely used as an antifouling agent that may cause reproductive toxicity. The mechanism of TBT on Leydig cell development is still unknown. The objective of the present study was to investigate whether a brief exposure to

Speciation without chromatography: Part I. Determination of tributyltin in aqueous samples by chloride generation, headspace solid-phase microextraction and inductively coupled plasma time of flight mass spectrometry [PDF]

open access: yes, 2001
An analytical procedure was developed for the determination of tributyltin in aqueous samples. The relatively high volatility of the organometal halide species confers suitability for their headspace sampling from the vapour phase above natural waters or

Influence of Airborne‐Particle Abrasion and Thermal Cycling on Enamel Bond Strength and Roughness of Lithium Disilicate Treated With a Self‐Etching Ceramic Primer

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study investigated the effect of a self‐etching ceramic primer (Monobond Etch & Prime [MEP]), with or without aluminum oxide airborne‐particle abrasion, on the surface roughness, and microtensile bond strength (μTBS) of lithium disilicate bonded to enamel, compared with the conventional hydrofluoric acid plus silane (HF

Toxic Effects of Tributyltin, Triphenyltin, and SnCl2 on the Development of Zebrafish (Danio rerio) Embryos

open access: yesAquaculture, Fish and Fisheries
Tin (Sn) is one of the heavy metals to which various functions in biological development are attributed in small quantities, for example, a role in cell structure, enzyme activities, and protein and carbohydrate metabolism in fish.
