Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

The Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Why are Chloris gayana leaves shorter in salt-affected plants? Analyses in the elongation zone [PDF]

, 2006
Reduced hydraulic conductance calculated from growth data was suggested to be the main reason for reduced leaf expansion in salt-stressed Chloris gayana (Rhodes grass). In this work, xylem vessel cross-sections and wall enzyme activities were analysed to

Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

The Anatomical Record, EarlyView.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Reconsolidation or Extinction: Transcription Factor Switch in the Determination of Memory Course after Retrieval [PDF]

, 2011
In fear conditioning, aversive stimuli are readily associated with contextual features. A brief reexposure to the training context causes fear memory reconsolidation, whereas a prolonged reexposure induces memory extinction. The regulation of hippocampal

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Contrasting CO2‐response strategies in Pardina lentils: Yield maximization in a commercial cultivar and seed composition adjustment in a landrace

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Assessing crop's responses to elevated carbon dioxide (eCO2) is crucial for global food security. This study examines the impact of eCO2 (700 μmol mol−1) on the cultivars of lentil (Lens culinaris), local Pardina Verde Rayada lentil (PVRL), and commercial Pardina lentil (PL) in terms of the productivity and nutritional composition ...
