Article Synopsis
- Protamines are proteins vital for sperm chromatin condensation, with their expression ratios linked to fertility in different species.
- The study aimed to evaluate RNA quality and protamine gene expression in testis samples from wild-derived mice, preserved under various conditions over different time frames.
- Results indicated that samples preserved in RNAlater® or NAP buffer at -80°C maintained RNA integrity and protamine expression effectively, even under less optimal conditions like room temperature for a week.
Background: Pleural effusions are challenging to diagnose, with approximately 20-50% of malignant effusions not diagnosed by cytology. Human epididymal protein 4 (HE4) may be useful in the differential diagnosis of pleural effusions. In serum, this biomarker shows false-positive results in some benign diseases.

Article Synopsis
- Probiotics have recently gained attention for their potential therapeutic effects, but their impact on reproductive health remains under-researched.
- This study tested the effects of two probiotic mixtures on sperm quality in mice, comparing them to a control group that received physiological serum.
- Results indicated that probiotic treatments resulted in a higher percentage of normal sperm and altered head shape, although they didn't significantly improve overall motility compared to controls, suggesting further research is needed.
The CO methanation performance of Mg- and/or Ce-promoted Ni catalysts supported on cellulose-derived carbon (CDC) was investigated. The samples, prepared by biomorphic mineralization techniques, exhibit pore distributions correlated to the particle sizes, revealing a direct effect of the metal content in the textural properties of the samples. The catalytic performance, evaluated as CO conversion and CH selectivity, reveals that Ce is a better promoter than Mg, reaching higher conversion values in all of the studied temperature range (150-500 °C).

Lessonia spicata is the most important habitat-forming kelp species in the intertidal along the central and south shores of Chile, and currently there are no morphometric and population studies of L. spicata (or other seaweed species) nor studies about the effects of pollution on its development in QB and neighbouring sites.
