Honoring Hartmut Karl Lichtenthaler, innovative pioneer of photosynthesis, on his 90 birthday.

We honor Professor Hartmut Karl Lichtenthaler, a versatile pioneer of photosynthesis research, plant physiology, isoprenoid biochemistry, and stress physiology of plants, for his groundbreaking and creative contributions to plant science. His innovative research on the chemical composition, ultrastructure, and function of chloroplasts and his detection of the major methylerythritol 4-phosphate (MEP) isoprenoid biosynthetic pathway in plants is key to our current understanding of the physiology and biochemistry of photosynthesis systems. His ingenious use of the powerful laser-induced chlorophyll fluorescence imaging has helped us better understand the stress response processes in plant leaves.

Uptake and perceptions of voluntary medical male circumcision among HIV-negative men in serodiscordant relationships in Zambia (2012-2015).

Voluntary medical male circumcision (VMMC) is a recommended HIV prevention strategy that few studies have promoted to HIV-negative men in serodiscordant relationships. We conducted a cross-sectional study on uptake and perceptions of VMMC among serodiscordant couples between 2012 and 2015. Heterosexual couples attending couples voluntary counselling and testing for HIV who had discordant results (M-, F+) were referred for VMMC.

The effect of constitutive root isoprene emission on root phenotype and physiology under control and salt stress conditions.

Isoprene, a volatile hydrocarbon, is typically emitted from the leaves of many plant species. Given its well-known function in plant growth and defense aboveground, we examined its effects on root physiology. We used isoprene-emitting (IE) lines and a non-emitting (NE) line of Arabidopsis and investigated their performance by analyzing root phenotype, hormone levels, transcriptome, and metabolite profiles under both normal and salt stress conditions.

Scoping Literature Review of Disease Modeling of the Opioid Crisis.

Opioid misuse continues to cause significant harm. To investigate current research, we conducted a scoping literature review of disease spread models of opioid misuse from January 2000 to December 2022. In total, 85 studies were identified and examined for the opioids modeled, model type, data sources used and model calibration and validation.
