... A 35-day experiment was conducted with a total of 105 rainbow trout (Oncorhynchus mykiss) with an average initial weight of 192.9 g, sampled over four time points (day 7, 14, 21, and 28) to study the relationship between respectively, δ¹³C in muscle, liver, and adipose fin and relative weight gain, when fed a diet based on plant C3 ingredients, with a lower level of δ¹³C compared to the baseline d ...

Abstract:
... The physiological mechanisms underpinning adaptations to starvation and cold stresses have been extensively studied in Drosophila, yet the understanding of correlated changes in stress-related and life-history traits, as well as the energetics of stress tolerance, still remains elusive. To answer the questions empirically in this context, we allowed D. melanogaster to evolve for either increased s ...
... Jouandin et al. (2022) show that lysosomal-derived cysteine serves as a signal to promote the tricarboxylic acid (TCA) cycle and suppress TORC1 signaling for Drosophila to endure starvation periods. ...
starvation, etc ; autophagosomes; autophagy; fluorescence; Show all 4 Subjects
Abstract:
... Autophagy is a process for the degradation and recycling of intracellular components and dysfunctional organelles. We developed an indole-embedded fluorescent naphthalimide for the selective imaging of autophagosomes in live cells. It was shown as intense puncta in the fluorescence confocal images and co-localizes with an autophagosome marker, LC3-RFP. In addition, it was applied to cellular autop ...
starvation, etc ; dormancy; energy; environment; sludge; Show all 5 Subjects
Abstract:
... Anaerobic granular sludge (AnGS) is the core of anaerobic granular sludge bed system. In this study, the effect and its mechanism of stopping substrate supply on function of AnGS were investigated. The cutoff of exogenous substrate supply triggered AnGS to enter the dormant state. Some methanization microorganisms sporulated. The number and activity of methanization microorganisms based on 16S rDN ...

Abstract:
... Bio-organic hybrid self-assemblies based on amino acids, conjugated polymers, Fe³⁺ and enzymes are fabricated with tumor environment-responsive and light-triggered NO release properties. By sequential energy consumption, NO attack and immune activation, FFPG shows boosted antitumor activity toward both primary and distant tumors. The three-level cascade strategy (starvation/NO/immunotherapy) adopt ...

Abstract:
... This study focused on the effects of substrate (raw wastewater) on the biological removal of 20 pharmaceuticals in moving bed biofilm reactors. This is the first study discriminating experimentally between effects of adaptation (45 d) and stimulation (100 h) on the removal of micropollutants. The results presented in this paper show: i) Tramadol and venlafaxine are subject to microbial N-oxidation ...
starvation, etc ; phosphates; rice; transcription (genetics); vesicular arbuscular mycorrhizae; Show all 5 Subjects
Abstract:
... A recent groundbreaking study by Shi et al. reveals an extensive transcriptional regulatory network for arbuscular mycorrhizal (AM) symbiosis in rice. The finding that phosphate starvation response (PHR) transcription factors centrally orchestrate the direct and indirect AM pathways for inorganic phosphate (Pi) uptake in rice opens a wealth of opportunities for plant breeding to enhance nutrient a ...

Abstract:
... Hsieh et al. (2022) reveal that carbon starvation elicits an unexpected compensatory reallocation of histone acetylation to establish an adaptive gene expression program, demonstrating how chromatin may integrate cellular carbon flow via histone acetylation with gene regulation. ...
starvation, etc ; autophagy; cancer therapy; caspase-3; cell viability; glucose; Show all 6 Subjects
Abstract:
... Cancer cells are metabolically altered cells characterized by higher glucose uptake. Understanding cancer cells is vital in cancer therapy. We aimed to analyze glucose starvation effect on cell viability parameters in healthy (BEAS-2B) and cancer (A549) cells. We analyzed mTOR, p21, caspase-3, beclin-1, ATG-12 mRNA levels in cells after 8 and 24 h starvations. We also counted senescent cells post- ...
starvation, etc ; Psetta; aquaculture; growth models; juveniles; research; satiety; turbot; Show all 8 Subjects
Abstract:
... Turbot (Psetta maxima) is a commercially valuable species in aquaculture, and the new strategies and models for growth are essential for rapid growth in aquaculture operations. Hence, the objectives of this study were to assess the best feeding protocol and growth model for turbot in culture conditions. Over a period of 2 years, growth data were recorded for the determination of the most suitable ...
starvation, etc ; Arabidopsis; genes; mutation; nutrient availability; phenotype; root hairs; Show all 7 Subjects
Abstract:
... Root hair growth is tuned in response to the environment surrounding plants. While most previous studies focused on the enhancement of root hair growth during nutrient starvation, few studies investigated the root hair response in the presence of excess nutrients. We report that the post‐embryonic growth of wild‐type Arabidopsis plants is strongly suppressed with increasing nutrient availability, ...
starvation, etc ; air; catalysts; electric potential difference; fuel cells; hydrogen; Show all 6 Subjects
Abstract:
... Air starvation occurring in a proton exchange membrane fuel cell will result in voltage drop and even a slightly reversal. However, a short period of air starvation may have a beneficial effect on the cell. In this paper, single cells are used to simulate the air starvation of a single cell in the stack and the related phenomena are studied. The experimental results show that when the starvation o ...

Abstract:
... The purpose of this retrospective study was to describe the causes of morbidity and mortality in free-ranging raptors admitted to a wildlife rehabilitation center (WRC) in Abruzzo Italy from 2005 to 2016 and the associated risk factors. A total of 2496 free-ranging raptors were included in the study. We analyzed the raptors’ medical records, epidemiological information, bird characteristics, cause ...

Abstract:
... Starvation conditions were inevitably encountered by biological wastewater treatment systems. Four anaerobic starvation periods (5, 10, 16 and 20 days) were conducted to investigate the response mechanism of denitrifying phosphate-accumulating organisms (DPAOs) in order to dissect denitrifying phosphorus removal (DPR) decay processes. The denitrifying phosphorus removal performance suffered with t ...

Abstract:
... Early arrival traveltime tomography and full waveform inversion were conducted on downward continued streamer seismic data at Dante's Domes oceanic core complex (OCC), providing unprecedented details of shallow P wave velocity structure. Together with reverse time migration images, seafloor morphology, in situ geological samples, magnetic and gravity data, the seismic constraints are used to infer ...

Abstract:
... The objective of the present paper was to discuss the design of farrowing pens and present the first production results of the “SowComfort farrowing pen” (SOWCOMF). The biggest difference between this pen and the traditional pen (TRAD) presented in the study, is that SOWCOMF contains a nest area equipped with a rubber mattress, floor heating, a rack for straw and no separate creep area. It was pre ...
starvation, etc ; Amblyseius; cannibalism; diet; entomology; hunger; kin recognition; predatory mites; Show all 8 Subjects
Abstract:
... Cannibalism is a commonly found behaviour in the animal kingdom. The biggest concern of cannibalism is that it reduces the inclusive fitness of the cannibals by eliminating close relatives. Kin recognition is a strategy used by many cannibals to benefit from cannibalism without the cost of reducing their inclusive fitness by eating close relatives. Most members of the family Phytoseiidae are canni ...

Abstract:
... The covalent conjugation of ubiquitin family proteins is a widespread post-translational protein modification. In the ubiquitin family, the ATG8 subfamily is exceptional because it is conjugated mainly to phospholipids. However, it remains unknown whether other ubiquitin family proteins are also conjugated to phospholipids. Here, we report that ubiquitin is conjugated to phospholipids, mainly phos ...

Abstract:
... Autophagy is an intracellular degradation process and plays key roles in energy recycle and homeostasis maintenance during planarian regeneration. Although planarians provide an ideal model organism for studying autophagy in vivo, the molecular mechanism of planarian autophagy is still unknown. Here, we identify three autophagy-related (Atg) gene 1 homologs from Dugesia japonica and study their ro ...
