Occurrence of Intersex in the Marine Mussel (Mollusca: Bivalvia): Does Gonadal Parasitism Play a Role?

Intersexuality is a reproductive phenomenon that occurs in some gonochoric species and refers to the simultaneous presence of both male and female gametes within the same individual. Although this phenomenon has been reported in various invertebrate species, many aspects remain poorly understood, especially in marine mussels. However, it has been suggested that the prevalence of parasites within populations could induce the occurrence of intersex animals.

Does motivation lead to academic success, or conversely? Reciprocal relations between autonomous and controlled motivation, and mathematics achievement.

Background: While it's clear that autonomous motivation significantly boosts academic success, there are conflicting findings regarding the opposite relation. Besides, the reciprocal relations among controlled motivation and achievement present mixed results. Adequately distinguishing between variations among individuals and within individuals results key to acknowledge such relations.

Changes in Neutrophil-to-Lymphocyte Ratio During Venoarterial Extracorporeal Membrane Oxygenation.

Mortality remains elevated during venoarterial extracorporeal membrane oxygenation support (VA-ECMO) for cardiogenic shock and the role of inflammation is uncertain. By using the neutrophil-to-lymphocyte ratio (NLR), we investigated inflammatory dynamics during VA-ECMO and their relation to clinical outcomes. A single-center, retrospective cohort study was conducted.

The modulating effect of circulating carbohydrate antigen 125 on ST2 and long-term recurrent morbidity burden.

Soluble ST2 (sST2) is released in response to vascular congestion, inflammation, and pro-fibrotic stimuli. In heart failure (HF), elevated levels of sST2 are associated with a higher risk of adverse clinical outcomes. Emerging evidence suggests that carbohydrate antigen 125 (CA125) may act as a ligand that modulates the inflammatory response.
