Major research on photosynthesis has been carried out under steady light. However, in the natural environment, steady light is rare, and light intensity is always changing. Changing light affects (usually reduces) photosynthetic carbon assimilation and causes decreases in biomass and yield. Ecologists first observed the importance of changing light for plant growth in the understory; other researchers noticed that changing light in the crop canopy also seriously affects yield. Here, we review the effects of environmental and non-environmental factors on dynamic photosynthetic carbon assimilation under changing light in higher plants. In general, dynamic photosynthesis is more sensitive to environmental and non-environmental factors than steady photosynthesis, and dynamic photosynthesis is more diverse than steady photosynthesis. Finally, we discuss the challenges of photosynthetic research under changing light.

Blue light, defined as short-wavelength visible light ranging from 400 to 500 nm, is recognized for its high energy within the visible light spectrum. The prevalent use of light-emitting diodes (LEDs) has significantly increased exposure to blue light. Corneal endothelial cells (CECs) playing a crucial role in maintaining corneal transparency to get clear visual field.

The use of donor eggs, sperm and embryos in medically assisted reproduction (MAR) provide new possibilities for reproductive assistance and family-making. In clinical practice, it also brings to light questions of responsibility and ethical conduct. Despite this, fertility practitioners' reasoning in clinical decision-making remains surprisingly understudied.

Background: Smoking induces inflammation in the heart and intima layer of blood vessels by activating nuclear factor kappa B, which controls the transcription of immunoglobulin free light chain (FLC)-κ. FLC levels are indicative of higher mortality in the overall population and poorer prognoses in cardiovascular diseases. This study aimed to analyze the effect of smoking cessation (SC) on the levels of FLCs and markers of inflammation and heart failure.

Photophysical studies on the interaction of small molecules with various forms of nucleic acids are attracting attention nowadays in order to delineate the molecular level mechanism of various biological processes occurring in vivo. Herein, we employed vivid steady-state and time-resolved spectroscopic techniques to elucidate the detailed characterization of the binding interaction of a biologically active cationic dye thioflavin T (ThT) with double and triple helical forms of RNA - A.U duplex and U.

Background: Light therapy (LT) in Parkinson's disease improves sleep. Specific LT parameters require further study, including optimal frequency.
Objectives: We aimed to determine if once- or twice-daily bright white light therapy (BWLT) improves sleep.
