Residue changes and processing factors of thirteen pesticides during different tomato pickle processes.

Tomatoes grown in an experimental greenhouse were sprayed with 13 selected pesticides at the recommended field doses, and used for pickle processing. Three different pickle processing techniques (natural fermentation, starter added fermentation and canning) were applied during the trials. Two strains of were used as starter cultures in starter added fermentation trials.

Degradation Trends of Some Insecticides and Microbial Changes during Sauerkraut Fermentation under Laboratory Conditions.

The aim of this study was to monitor the degradation of three insecticides licensed for the control of cabbage moths during the 14-day fermentation period of sauerkraut samples. The hypothesis of this study is that the different sauerkraut fermentation processes could affect the degradation of applied insecticides. For this purpose, the fresh cabbage leaves contaminated with (λ-cyhalothrin, malathion, and chlorpyrifos-methyl) were left for fermentation with and without (natural) starter addition ( 112), and vacuum-packed as a control under laboratory conditions.

Simulation Study for the Degradation of Some Insecticides during Different Black Table Olive Processes.

The aim of this study was to determine the effects of different olive processing methods on deltamethrin (DEL), dimethoate (DIM), and imidacloprid (IMI), the most commonly preferred synthetic insecticides for controlling olive pests such as the olive fruit fly. The hypothesis is that the fermentation could accelerate the degradation process of the insecticides. For this purpose, olives were left for fermentation (natural black olives) without and with starter addition (two strains 112 and 123) and processed as dehydrated black olives.

Inadvertent insertion of hearing aid impression material into the middle ear: Case report and implications for future community hearing services.

Introduction: The creation of ear moulds for hearing aids is generally considered a safe and routine procedure for trained professionals. In the literature there are reports of otological complications caused by hearing aid mould impression material in the middle ear cavity but such complications are considered rare.

Presentation Of Case: We present the case of a patient in whom impression material entered the middle ear through a perforation of the tympanic membrane during the process of making a hearing aid mould and review how this was managed.

Historical review: Peptidyl transfer, the Monro era.

The peptide bond-forming reaction of protein synthesis, the peptidyl transfer reaction, takes place in a region of the 50S ribosomal subunit that consists entirely of RNA, the peptidyl transferase centre. Basic to the present knowledge of peptidyl transfer was the discovery by Robin Monro and his colleagues in the 1960s that the reaction is catalyzed by the 50S ribosome. The Monro experiments, and the historical context in which they were conceived, are described in this personal recollection.
