Response of the Saccharomyces cerevisiae Mpk1 Mitogen-Activated Protein Kinase Pathway to Increases in Internal Turgor Pressure Caused by Loss of Ppz…
2004
ABSTRACT The Mpk1 pathway of Saccharomyces cerevisiae is a key determinant of cell wall integrity. A genetic link between the Mpk1 kinase and the Ppz phosphatases has been reported, but the nature of this connection was unclear. Recently, the Ppz phosphatases were shown to be regulators of K + and pH homeostasis. Here, we demonstrate that Ppz-deficient strains display increased steady-state K + levels and sensitivity to increased KCl concentrations. Given these observations and the fact that K + is the major determinant of intracellular turgor pressure, we reasoned that the connection between PPZ1 and - 2 and MPK1 was due to the combination of increased internal turgor pressure in Ppz-defic…
Molecular response of Saccharomyces cerevisiae wine and laboratory strains to high sugar stress conditions.
2010
One of the stress conditions that can affect Saccharomyces cerevisiae cells during their growth is osmotic stress. Under particular environments (for instance, during the production of alcoholic beverages) yeasts have to cope with osmotic stress caused by high sugar concentrations. Although the molecular changes and pathways involved in the response to saline or sorbitol stress are widely understood, less is known about how cells respond to high sugar concentrations. In this work we present a comprehensive study of the response to this form of stress which indicates important transcriptomic changes, especially in terms of the genes involved in both stress response and respiration, and the i…
Roles of sorbitol and sucrose in growth and respiration of ‘Encore’ peach fruit in the three developmental stages
2002
In peach [Prunus persica (L.) Batsch (Peach Group)], both sorbitol and sucrose are utilized for source to sink carbon (C) transport, yet their specific functions in fruit growth and development remain unclear. Growth rate (GR), respiration rate (R), carbohydrate content, and the activities of sorbitol dehydrogenase (SDH), sorbitol oxidase (SOX), sucrose synthase (SS), acid invertase (AI), and neutral invertase (NI) were determined in ‘Encore’ peach fruit to study the specific functions of sorbitol and sucrose in each phase of fruit development (an early period of rapid cell division, a relatively inactive intermediate stage where endocarp (pit) hardening occurs, and a final swelling due to …

Lefschetz fixed-point theorem furnishes a way for counting the fixed points of a suitable mapping. In particular, the Lefschetz fixed-point theorem states that if Lefschetz number is not zero, then the involved mapping has at least one fixed point, that is, there exists a point that does not change upon application of mapping. ewline Let $f={f_q}:E o E$ be an endomorphism of degree zero of graded vector space $E={E_q}$. Let $ ilde{E}=E setminus {x in E : f^n(x)=0, mbox{ for some }n in mathbb{N}}$. Define the generalized Lefschetz number $Lambda(f)$ by $$Lambda(f)=sum_{q geq 0}(-1)^qmbox{Tr}(f_q),$$ where $mbox{Tr}(f)=mbox{tr}( ilde{f})$ is the generalized trace of $f$, ``tr'' is the ordinar…
IPERSENSIBILITÀ AL GLUTINE NELL’ANZIANO. PRESENTAZIONE DI UN CASO CLINICO
2015
La celiachia è una malattia immunomediata scatenata dall’ingestione di glutine che, in soggetti geneticamente predisposti, determina un processo infiammatorio intestinale con conseguente malassorbimento e manifesta-zioni extraintestinali. Fino ad alcuni anni fa era considerata una patologia rara, tipica dell’età infantile; lo scenario epidemiologico della celiachia, oggi, è totalmente cambiato, grazie anche all’introduzione di test sierologici ad elevata sensibilità e specificità come gli anticorpi anti-endomisio (EMA) e gli anticorpi anti-transglutaminasi tissutale (tTG). Studi epidemiologici basati sull’impiego dei test sierologici hanno dimostrato che la diagnosi di celiachia viene sempr…

Response of yeast cells to high glucose involves molecular and physiological differences when compared to other osmostress conditions.
2015
Yeast cells can be affected by several causes of osmotic stress, such as high salt, sorbitol or glucose concentrations. The last condition is particularly interesting during natural processes where this microorganism participates. Response to osmostress requires the HOG (High Osmolarity Glycerol) pathway and several transcription factors, including Hot1, which plays a key role in high glucose concentrations. In this work, we describe how the yeast response to osmotic stress shows differences in accordance with the stress agent responsible for it. Compared with other conditions, under high glucose stress, delocalization of MAPK (Mitogen-Activated Protein Kinase) Hog1 is slower, induction of …
The monolingual habitus of German society challenging the interests of an autochthonous minority language : Linguistic landscapes in the Sorbian “cap…
2019
This paper analyzes the LL in the city of Bautzen / Budyšin in Germany, a town which is frequently considered the “capital” of the Slavonic minority of the Sorbs. It focuses on the societal role of Sorbian in relation to practices and ideologies of mainstream German society. The vast majority of signs in Bautzen / Budyšin are in German only. Sorbian is essentially restricted to explicitly Sorbian institutions and to local and regional administration. Interviews conducted in shops and on the streets reveal that paternalistic attitudes common to perceptions of language policies and minority languages in Germany dominate; practices maintain the common monolingual habitus in German society.
