Opis:
The yeast Saccharomyces cerevisiae strain W303 synthesizes in the early logarithmic phase of growth dolichols of 14-18 isoprene residues. The analysis of the polyisoprenoids present in the stationary phase revealed an additional family which proved to be also dolichols but of 19-24 isoprene residues, constituting 39% of the total dolichols. The transfer of early logarithmic phase cells to a starvation medium lacking glucose or nitrogen resulted in the synthesis of the longer chain dolichols. The additional family of dolichols represented 13.8% and 10.3% of total dolichols in the glucose and nitrogen deficient media, respectively. The level of dolichols in yeast cells increased with the age of the cultures. Since both families of dolichols are present in stationary phase cells we postulate that the longer chain dolichols may be responsible for the physico-chemical changes in cellular membranes allowing yeast cells to adapt to nutrient deficient conditions to maintain long-term viability.

The 60Co and 137Cs bioaccumulation by Helianthus annuus L. was measured during 9 day cultivation at 20 š 2°C in hydroponic Hoagland medium. Previous starvation for K+ and for NH4 + 2.2 and 2.7 times, respectively, enhanced 137Cs uptake rate. Previous cultivation in surplus of K+ ions 50 mmol.l 1 has no effect on 137Cs bioaccumulation rate. Both 137Cs and 60Co bioaccumulation significantly increase with dilution of basic Hoagland medium up to 1:7 for caesium and up to 1:3 for cobalt followed by mild decrease at higher dilutions. Root to shoot specific 137Cs radioactivity ratio (Bq.g 1/Bq.g 1, fresh wt.) increased with dilution from 1.46 to 9.6-9.8. The values root to shoot specific radioactivity ratio for 60Co were less dependent on the nutrient concentrations and were within the range 5.7 to 8.5. 137Cs was localized mainly in young leaves (30%) and roots (39%) and 60Co mainly in roots (67%) and leaves (20%). Obtained data showed less sensitivity of 60Co uptake by sunflower on nutrient concentration in hydroponic media.

Opis:
Yeast ScAtg2, an autophagy-related protein, is highly conserved in other fungi and has two homologues in humans, one of which is hAtg2A encoded by the hATG2A/KIAA0404 gene. Region of homology between Atg2 and hAtg2A proteins comprises the C-terminal domain. We used yeast atg2D strain to express the GFP-KIAA0404 gene, its fragment or fusions with yeast ATG2, and study their effects on autophagy. The GFP-hAtg2A protein localized to punctate structures, some of which colocalized with Ape1-RFP-marked preautophagosomal structure (PAS), but it did not restore autophagy in atg2Δ cells. N-terminal fragment of Atg2 and N-terminal fragment of hAtg2A were sufficient for PAS recruitment but were not sufficient to function in autophagy. Neither a fusion of the N-terminal fragment of hAtg2A with C-terminal domain of Atg2 nor a reciprocal fusion were functional in autophagy. hAtg2A, in contrast to yeast Atg2, did not show interaction with the yeast autophagy protein Atg9 but both Atg2 proteins showed interaction with Atg18, a phospholipid-binding protein, in two-hybrid system. Moreover, deletion of ATG18 abrogated PAS recruitment of hAtg2A. Our results show that human hAtg2A can not function in autophagy in yeast, however, it is recruited to the PAS, possibly due to the interaction with Atg18.

Opis:
Podisus maculiventris (Say) is a generalist predator attacking many insect species from different orders. The bug injects saliva into its prey's body. The ingested hemolymph and liquefied internal tissues pass through the bug's alimentary tract. Collagenase working on peptide bonds of collagen and basement membrane proteins, leads to the disintegration of the prey's internal organs. As yet, there is an almost complete lack of knowledge on the collagenase activity in P. maculiventris. The collagenase activity of the salivary glands and midgut was optimum at pH 8.0 which was congruent with the optimal pH of the total proteolytic activity of the salivary glands. More collagenolytic activity was determined in the posterior lobe of the salivary glands and anterior midgut. Significant inhibition of collagenolytic activity by ethylenediaminetetraacetic acid (EDTA) revealed the enzyme is a metalloproteinase. The collagenase activity notably decreased when the bug went hungry. The salivary gland collagenase is a vital enzyme in extra-oral digestion and facilitates the action of other digestive enzymes. The midgut collagenase may be involved in the digestion of the ingested muscle fibers. The collagenase probably acts as an intoxicating agent in the saliva (venom) of P. maculiventris. Paralysing toxins are present in the salivary gland secretion.

Opis:
Autofagia jest bardzo starym procesem, podczas którego przy pomocy lizosomów usuwane są białka o długim okresie półtrwania oraz organella komórkowe. Autofagia może być wywołana przez mechanizmy stresowe dla komórki. Badania dowodzą, że autofagia odgrywa kluczową rolę w pozyskiwaniu składników odżywczych oraz w adaptacji do warunków głodu. Dzięki temu bierze udział w zachowaniu homeostazy w cytoplazmie i jądrze komórki. Osiągnięcie tego celu możliwe jest kilkoma drogami. W zależności od tego w jaki sposób substrat zostaje połączony z lizosomem mówimy o: makroautofagii oraz mikroautofagii. Dodatkowo część autorów wyróżnia również autofagię zależną od chaperonów. W niniejszym artykule opisano mechanizmy molekularne poszczególnych rodzajów autofagii ze szczególną uwagą poświeconą makroautofagii- jako najlepiej poznanemu typowi autofagii.
Autophagy is an extremely old process during which long-lived proteins and cellular organelles are removed by means of lysosomes. Autophagy may be caused by cellular stress mechanisms. Research has proven that autophagy plays a key role in obtaining nutrients and adapting to the conditions of starvation. Owing to this, it takes part in maintaining homeostasis in cytoplasm and cell nucleus. This objective may be achieved through a number of ways. Depending on the manner in which a substrate connects with the lysosome, we can talk about macroautophagy and microautophagy. Additionally, some authors also distinguish a chaperone-mediated autophagy. The article presented below describes molecular mechanisms of each type of autophagy and focuses particularly on macroautophagy, which is the best understood of all the autophagy types.

Opis:
The aim of this study was to highlight the interest of using CFD technique as a diagnostic tool of a malfunctioning Solid Oxide Fuel Cells. Hydrogen starvation of a SOFC due to nitrogen dilution is one of the cell dysfunctions and can lead to its degradation. Identification of the starvation point allows to improve cell performance and establish the best conditions for degradation tests. To illustrate a potential of the CFD tool, several simulations of a single planar SOFC and its behaviour under hydrogen starvation were performed and analysed. The results showed that at lower cell voltage values of 0.3 and 0.5 V significant gradients in the electric current were noticed due to a local reduction in hydrogen concentration. The CFD analysis allowed defining desirable mass flow rate of hydrogen to SOFCs to avoid fuel starvation. The model constitutes a helpful tool for optimizing cell design and operational conditions.

Opis:
Violent crises orchestrated by the activities of an Islamist extremist group in Nigeria, Boko Haram, besides resulting in the destruction of lives and properties in many communities in North East, Nigeria, contribute significantly to mobility of languages. A vast number of survivors who fled from the volatile areas inadvertently moved to different refugee camps designated by the Nigerian government as Internally Displaced Persons (IDP) camps. Given the fact that the linguistic ecology of North East Nigeria is extremely diverse, the situation where people from diverse linguistic backgrounds co-habit in camps under austere conditions would yield to some sociolinguistic issues including language politics and language endangerment, among others. The IDP camps attract the attention of international agencies such as UNHCR and national groups who send their representatives for sundry purposes. The language of the visitors is often a global language, English, whereas the displaced people in the camps are from diverse linguistic backgrounds with Hausa as the most popular language. In this situation, some persons in the camp are bound to encounter some language and communication challenges. Using some principles from Ecolinguistics, this study examined the linguistic repertoires of people living in some selected IDP camps in North East Nigeria. The instrument for data collection were interviews, observation and focus group discussions. The information from the study highlights the challenges of the traumatized persons who are grappling with communication challenges, the diverse sociolinguistic issues derived from the linguistic practices and the precarious situation of the languages on the move. The information from the study directs attention to the current trends in the bustling linguistic ecology of Nigeria and the need to take proactive measures to maintain the rich cultural heritage.

Opis:
The main hormone produced by the adrenal glands of hens is corticosterone, synthesized and secreted by stimulation of the HPA axis during stress. Direct activation of adrenal activity is conditioned by ACTH, which binds to the melanocortin receptor cMC2 in the adrenals and stimulates the synthesis and release of glucocorticosteroids. One of the factors that stimulate HPA axis activity is starvation, to which chickens are very sensitive. The purpose of this study was to determine the expression of ACTH receptor cMC2 in the adrenals of hens during short- term fasting and after restoration of the proper level of nutrition (refeeding). The results of the experiment show that 24-hour food deprivation is stressful for the hen, as indicated by increased concentrations of corticosterone in the adrenals and blood plasma. Changes in cMC2R expression and the level of corticosterone in the adrenals during fasting and refeeding indicate a rapid increase in HPA axis activity in response to changing levels of nutrition. The results of the experiment confirm the direct effect of ACTH on corticosterone release by avian adrenal glands.
