The effects of dietary soyabean oil-cake meal on performance and gut histology of piglets

The effects of four diets containing different protein sources on the performance and gut histology of piglets were compared. The diets contained as the main protein sources either: milk powder plus fishmeal, milk powder plus high-protein (48% crude protein) soyabean oil-cake meal, fishmeal plus high-protein soyabean oil-cake meal or high-protein soyabean oil-cake meal alone. No differences (p > 0.05) were observed between treatments for average daily gain, feed conversion ratio, intake or intestinal villus height. It was concluded that high-protein soyabean oil-cake meal can be utilised successfully in diets for weaner pigs either in combination with other protein sources or as main protein source without detrimental effects on production parameters or gut histology. These results apply to diets are formulated on the basis of digestible amino acids using soyabean oil-cake meal has been correctly processed.

Carbonic anhydrases CA1 and CA4 function in atmospheric CO2-modulated disease resistance

Main conclusion Carbonic anhydrases CA1 and CA4 attenuate plant immunity and can contribute to altered disease resistance levels in response to changing atmospheric CO2 conditions. Abstract β-Carbonic anhydrases (CAs) play an important role in CO2 metabolism and plant development, but have also been implicated in plant immunity. Here we show that the bacterial pathogen Pseudomonas syringae and application of the microbe-associated molecular pattern (MAMP) flg22 repress CA1 and CA4 gene expression in Arabidopsis thaliana. Using the CA double-mutant ca1ca4, we provide evidence that CA1 and CA4 play an attenuating role in pathogen- and flg22-triggered immune responses. In line with this, ca1ca4 plants exhibited enhanced resistance against P. syringae, which was accompanied by an increased expression of the defense-related genes FRK1 and ICS1. Under low atmospheric CO2 conditions (150 ppm), when CA activity is typically low, the levels of CA1 transcription and resistance to P. syringae in wild-type Col-0 were similar to those observed in ca1ca4. However, under ambient (400 ppm) and elevated (800 ppm) atmospheric CO2 conditions, CA1 transcription was enhanced and resistance to P. syringae reduced. Together, these results suggest that CA1 and CA4 attenuate plant immunity and that differential CA gene expression in response to changing atmospheric CO2 conditions contribute to altered disease resistance levels

Влияние стандартных схем противоязвенной терапии на клинико-лабораторные показатели у пациентов с язвенной болезнью двенадцатиперстной кишки

При изучении влияния стандартных схем квадритерапии второй линии на динамику клинико−лабораторных показателей у пациентов с язвенной болезнью двенадцатиперстной кишки установлено, что схемы с омепразолом, де−нолом, амоксициллином, тетрациклином и омепразолом, де−нолом, тетрациклином, метронидазолом одинаково влияют на динамику клинических симптомов и частоту эрадикации H. рylori. Однако первая схема более эффективно воздействует на нарушенные механизмы синтеза защитного слизистого барьера и процессы регенерации, что способствует более высокой частоте рубцевания язвы.При вивченні впливу стандартних схем квадрітерапії другої лінії на динаміку клініко−лабораторних показників у пацієнтів із виразковою хворобою дванадцятипалої кишки встановлено, що схеми з омепразолом, де−нолом, амоксициліном, тетрацикліном та омепразолом, де−нолом, тетрацикліном, метронідазолом однаково впливають на динаміку клінічних симптомів і частоту ерадикації H. рylori. Однак перша схема ефективніше впливає на порушені механізми синтезу захисного слизового бар'єру і процеси регенерації, що сприяє більш високій частоті рубцювання виразки.The investigation of the effect of standard schemes of second−line quadritherapy on the dynamics of clinical and laboratory parameters in patients with duodenal ulcer disease revealed that the scheme with Omeprazole, De−Nol, Amoxicillin, Tetracycline and Omeprazole De−Nol, Tetracycline, Metronidazole influence equally the dynamics of clinical symptoms and frequency of eradication of H. pylori. However, the first scheme more effectively influenced the disorders in the mechanism of synthesis of protective mucus barrier and regeneration processes, which contributed to the high frequency of ulcer cicatrisation

’n Kort rit in ’n vinnige voertuig

In 1986 het Piet Roodt en Elize Botha my genader om deel van Tydskrif vir Letterkunde se skakelredaksie te word. My hooftaak was om ingestuurde poësie te keur en later te help met die saamstel van die tydskrif. Een hoogtepunt was die saamstel van ’n gerf geleentheidsverse ter nagedagtenis aan Stephen le Roux (Etienne Leroux, 1990). Teen die einde van die tagtigerjare het ek en Piet die meeste van die werk gedoen; prof. Elize kondig einde 1992 aan dat sy uittree as redakteur
