Vagal control of pulmonary peripheral circulation in the rattlesnake modulates relevant hemodynamic adjustments to temperature change [0.03%]
温度变化时迷走神经对响尾蛇肺周围循环的控制调节相关的血流动力学改变

Samanta A Castro et al.
The vagal influence over large pulmonary arteries has been clearly demonstrated in Squamates. Additionally, diverse in situ experiments suggest that pulmonary circulation was either not responsive or much less responsive than the systemic c...
Voltage-gated K+ channels modulate the neural abiotic stress tolerance of Drosophila melanogaster [0.03%]
电压门控钾通道调节果蝇的神经非生物胁迫耐受性
Mads Kuhlmann Andersen,Dawson B H Livingston,R Meldrum Robertson et al.
Mads Kuhlmann Andersen et al.
Severe abiotic stress causes insects to lose nervous function and enter a state of paralytic coma. Central to this loss of function is a spreading depolarization (SD), where a characteristic collapse of ion gradients depolarizes neuronal an...
Integrated transcriptomic and proteomic analyses reveal the physiological stress responses and adaptive mechanisms of Macrobrachium nipponense to carbonate alkalinity [0.03%]
整合转录组和蛋白质组分析揭示了日本沼虾对碳酸盐碱度的生理应激反应和适应机制
Yiming Li,Chenxi Zhu,Zongli Yao et al.
Yiming Li et al.
To explore the effect of carbonate alkalinity stress on the East Asian river prawn (Macrobrachium nipponense), specimens were cultured at three alkalinity levels (0, 10, and 20 mmol/L NaHCO3) for 96 h. We employed integrated transcriptomic ...
Not the cAMP/PKA pathway but the cGMP/PKG pathway promotes branchial ammonia excretion in the green shore crab, Carcinus maenas [0.03%]
环腺苷酸/蛋白激酶A而非环鸟苷酸/蛋白激酶G途径促进绿绳索蟹(Carcinus maenas)的鳃氨排泄
Baoyue Zhang,Dirk Weihrauch

Ammonotelic animals excrete their toxic waste ammonia directly into the surrounding environment. To deal with conditions causing elevated hemolymph ammonia levels, such as feeding, an efficient ammonia excretion process must be in place to ...
Gonadic cycle and environmental modulation of P450 aromatase localization in Cerastoderma glaucum ovary from Monastir Bay [0.03%]
突触周期和环境对蒙塔尔自然湾凤螺卵巢P450芳香化酶定位的调节作用
Imen Hmidi,Lorenzo Riccio,Teresa Chianese et al.
Imen Hmidi et al.
The gonadic cycle of bivalve molluscs is highly variable and depends on several factors, including the geographical location and environmental conditions of the populations. The aim of this study was to analyse the gonadic cycle of Cerastod...
Endogenous trade-offs among organs across seasonal reproductive states in the spotted munia (Lonchura punctulata) [0.03%]
季节性繁殖状态下斑文鸟器官间的内源性权衡关系研究
Shirin Fatima,Sayantan Sur,Jyoti Tiwari et al.
Shirin Fatima et al.
Annual reproductive processes are timed by the endogenous circannual clock and environmental cues. Although seasonal phenotypic plasticity is well-documented in birds, the endogenous changes in organ size and histomorphometry are less chara...
Body mass shapes mitochondrial NADH and NADPH sources in mammalian skeletal muscle [0.03%]
肌糖元和脂质代谢决定哺乳动物骨骼肌中线粒体NADH和NADPH来源
Mélanie Boël,Yann Voituron,Damien Roussel
Mélanie Boël
Here, we investigate whether the elevated mitochondrial H2O2 release in small mammals arises from a tradeoff between NAD-dependent enzymes, which synthesizes NADH to support high oxidative phosphorylation, and NADP-dependent enzymes, which ...
The Captive Gut: the impacts of long-term captivity on the intestinal digestive enzyme activities of a marine herbivorous fish [0.03%]
被困的肠道：长期圈养对一种海洋草食性鱼类肠消化酶活性的影响
Jordan E Buckner,Leyna Vo,Michelle J Herrera et al.
Jordan E Buckner et al.
Given that digestion is largely a chemical process in fishes that do not masticate or triturate their food, digestive enzyme activities are frequently measured as indicators of what nutrients a fish can readily digest. Here, we explored wha...
Offspring innate immunity varies with parental age in a long-lived seabird [0.03%]
长寿海鸟后代先天免疫力随双亲年龄而异
Beatrice Berardi,Gianluca Damiani,Gábor Á Czirják et al.
Beatrice Berardi et al.
Parental age at reproduction is increasingly recognized as a factor influencing offspring lifespan and other fitness-related traits, yet the underlying proximate physiological mechanisms remain poorly understood. Immune function and oxidati...
Analysis of the transcriptional mechanisms of yellowfin tuna (Thunnus albacares) juveniles in response to acute cold stress in brain and muscle tissues [0.03%]
黄鳍金枪鱼仔鱼急性冷休克响应的脑和肌肉组织转录机制分析

La Nina events caused by global climate change have amplified ocean temperature fluctuations, challenging aquaculture operations for species such as yellowfin tuna (Thunnus albacares), particularly under winter cooling conditions. To invest...
