However, the metabolic and regulatory processes involved in pigment accumulation in. <i>B. napus</i> flowers are poorly understood. To address this knowledge gap, we conducted a multi-omics analysis of the orange-red-flowered 'OrP' and the yellow-flowered 'ZS11' rapeseed cultivars. The total anthocyanin content of 'OrP' petals was 5.420-fold and 3.345-fold higher than 'ZS11' petals at the S2 and S4 developmental stages, respectively. The red coloration of 'OrP' flowers resulted primarily from the presence of anthocyanin pigment derivatives. The up-regulated differentially expressed genes (DEGs) of four stages in 'OrP' were found to be significantly enriched in phenylpropanoid, flavonoid, and anthocyanin metabolism-associated GO and KEGG terms. Weighted Gene Co-expression Network Analysis (WGCNA) revealed that 51 DEGs were linked to anthocyanin metabolism, including several structural genes such as <i>BnaCHS</i>, <i>BnaF3H</i>, <i>BnaF3'H</i>, <i>BnaCHS</i>, <i>BnaDFR</i>, <i>BnaANS</i>, <i>BnaUGTs</i>, and the transcription factor (TF) genes <i>BnaHY5</i>, <i>BnaBBX22</i>, <i>BnaPIL1</i>, <i>BnaPAP2</i>, <i>BnaTT8</i>, <i>BnaTTG2</i>, and <i>BnaMYBL2</i>.

This narrative review synthesizes current evidence from embryological development, adult morphological studies, comparative mammalian anatomy, and clinical case reports to reassess the role of the PM in humans. Developmental data reveal that the PM is consistently present during fetal life, with tendon morphology and insertion patterns emerging early and resembling adult anatomical variants. Rather than indicating postnatal regression, it suggests a stable polymorphism rooted in prenatal development. Across mammalian species, the PM varies in presence and function, correlating with locomotor specialization from proprioception in primates to propulsion in carnivores, and absence in ungulates. In humans, high proprioceptive fiber density and anatomical variability support the hypothesis that the PM may be undergoing functional repurposing from a contractile to a sensorimotor role. Clinically, its relevance is evident in imaging interpretation, surgical tendon harvesting, and the pathophysiology of Achilles tendinopathy. Recent discoveries, including the identification of the plantaris ligamentous tendon (PLT), further underscore the complexity of this region and support the need to reassess its structural and clinical significance.

This study evaluated the concordance between taxonomic and FD metrics of benthic macroinvertebrates along a fluvial habitat quality gradient in the Paute River Basin, Ecuador. Macroinvertebrate communities were sampled over six years at twelve sampling points and assessed using four taxonomic metrics: Shannon diversity (H), the Margalef index (D<sub>Mg</sub>), family richness (N), and the Andean Biotic Index (ABI). Functional diversity was evaluated using four metrics: weighted functional dendrogram-based diversity (wFDc), Rao's quadratic entropy (Rao), functional dispersion (FDis), and functional richness (FRic). The fluvial habitat index (FHI) was used as an environmental reference to evaluate diversity metric responses. K-means clustering was independently applied to each metric, and pairwise concordance was quantified using the Measure of Concordance (MoC) and overlap in sampling points groupings across replicates. Most metrics (except FRic and N) showed clear responsiveness to the FHI gradient, confirming their ecological relevance. Strong structural concordance was observed between H and D<sub>Mg</sub> and the FD metrics Rao, FDis, and wFDc, showing that these metrics captured similar yet complementary aspects of community organization. In contrast, ABI showed marked sensitivity to the FHI gradient but low concordance with functional metrics, suggesting distinct dimensions of biological integrity not encompassed by trait-based metrics. These findings highlight the value of combining taxonomic and functional metrics to detect both broad and subtle ecological changes.

This study analyzes the expression of extrinsic and intrinsic apoptotic markers in the testicle and epididymis of rats exposed to chronic variable stress (CVS). We used male Wistar rats divided into two groups: the control group was kept undisrupted, and the stress group was stressed daily using a CVS model for four weeks, except for the weekends (from postnatal days 51 to 81). After the last week, the rats were sacrificed, and complete testicles and epididymal sperm were used to measure oxidative stress and the total antioxidant status by colorimetric methods. The expressions of PPAR-γ, p53, Bax, and Bcl-2 markers at the mRNA level were determined by real-time PCR, and the p-Akt, AP-2α, PPAR-γ, C/EBP-β and FAS protein levels were detected by immunoblot. The results showed low levels of p-Akt and AP-2α proteins and high levels of FAS, PPAR-γ, and C/EBP-β in the testicle and epididymis of rats exposed to CVS. At the mRNA level, we observed the upregulation of PPAR-γ, p53, p21, HIF-α, and Bax expressions in the epididymis of rats exposed to CVS, consistent with the significant caspase-3 activity observed in both the epididymis and testicles in the CVS group. In conclusion, CVS damage triggers the induction of apoptosis markers by intrinsic (PPAR-γ, p53, p21, HIF-α, and Bax) and extrinsic (p-Akt, AP-2α, and FAS) caspase-3-dependent pathways in complete extracts of both the testicles and epididymis.
