The role of lag phases between real-term marine heatwaves in the trait responses of two macrophyte species.

Coastal marine macrophytes are critical ecosystem engineers providing valuable ecosystem services. However, they experience detrimental impacts from climate change-induced stresses such as marine heatwaves (MHW), which are becoming more intense and frequent. This study investigated trait responses in real-term heatwaves, Continuous (1MHW) and Consecutive (with a 4-day lag phase, 2MHW), on two key macrophytes, the seaweed Fucus vesiculosus and seagrass Zostera marina.

Effect of Sexual Partnerships on Zika Virus Transmission in Virus-Endemic Region, Northeast Brazil.

The epidemiologic effects of Zika virus (ZIKV) sexual transmission in virus-endemic countries remain unclear. We conducted a 2-level, linear mixed-effects logistic regression analysis by using a recently acquired population-based ZIKV and chikungunya virus (CHIKV) serologic dataset obtained from persons residing in Northeast Brazil (n = 2,070 participants). We adjusted mathematical models for housing type and age of participants; the models indicated a significantly higher likelihood of ZIKV seropositivity among persons engaged in a sexual relationship within the same household (odds ratio 1.

PLLA/GO Scaffolds Filled with Canine Placenta Hydrogel and Mesenchymal Stem Cells for Bone Repair in Goat Mandibles.

Bone defects in animals can arise from various causes, including diseases, neoplasms, and most commonly, trauma. Comminuted fractures that exceed the critical size may heal poorly due to deficient or interrupted vascularization, resulting in an insufficient number of progenitor cells necessary for bone regeneration. In this context, 3D printing techniques using poly-L-lactic acid/graphene oxide (PLLA/GO) aim to address this issue by creating customized scaffolds combined with canine placenta hydrogel and mesenchymal stem cells for use in goat mandibles, compared to a control group using titanium plate fixation.
