Summary: The study aims to analyze the function of the myzorhynchus and remnant apical organ in adult cestodes of the Rhinebothriidea order. The structures were analyzed in 12 species from six genera and two families. The glandular composition of the myzorhynchus and remnant apical organ were studied using histochemical techniques and/or transmission electron microscopy. The findings suggest that the type of gland cells in these structures can be used for the diagnosis of certain genera.

Summary: This study provides a first-time description of the internal ultrastructure of the scolex and the histochemical composition of the apical glands in two South American proteocephalidean cestodes. Scanning and transmission electron microscopy were employed to observe the tegumental ultrastructure, while histochemical techniques were used to determine the types of gland secretion. Two types of glands were identified in the scolex, and the microtriches pattern for one species was confirmed, while for the other species, it was described for the first time. The presence of sensory receptors and the systematic value of certain characters were also discussed.

Summary: A novel complex neuro-glandular brain structure associated with sensory elements has been discovered in the plerocercoid parasite of Gadus morua from the White Sea. This structure, consisting of both nervous and glandular elements, is suggested as a model for the Diphyllobothriidae family. Significant differences in the architecture of the plerocercoid brain at the family level have been observed within the order Diphyllobothriidea. Serotonin, FMRFamide, and GABA-like immunoreactive neurons are present in various parts of the parasite.

Summary: The presence and composition of peroxisomes in different cell types of the human parotid gland were investigated in this study. Through various techniques, including biochemistry and microscopy, we found that peroxisomes are present in all cells of the parotid gland, with a higher abundance in striated duct cells compared to acinar cells. The study also revealed the presence of antioxidative enzymes, such as catalase, suggesting their role in protecting against oxidative stress in the parotid gland.

Summary: Salivary glands are crucial for tick feeding success and pathogen transmission. Previous studies have shown that neuropeptidergic axons innervate saliva-producing acini in Ixodes scapularis salivary glands and release different neuropeptides. One of these neuropeptides, SIFamide, along with its receptor, has been found to control the acinar valve. In this study, a second SIFamide receptor, SIFa_R2, was identified and characterized in I. scapularis salivary glands.

Summary: Dibothriocephalus ditremus and Dibothriocephalus latus are tapeworms native to Europe that can cause health issues in intermediate fish hosts or diphyllobothriosis in humans. This study aimed to understand the morphology of the frontal part of the tapeworm larvae, which is important for their establishment in fish tissues and attachment in final hosts. Through immunofluorescent labeling and confocal microscopy, the researchers observed the 3-dimensional microanatomy of the tapeworms. Similar patterns were found in the nervous system of both species, but differences were observed in the brain structure and sensilla size. Surprisingly, FMRF amide-like immunoreactivity was found in the terminal reservoirs of secretory gland ducts and excretory canals, suggesting the presence of FMRF amide-related peptides in secretory/excretory products.

Summary: Salivary glands develop through epithelial-mesenchymal interactions and are formed through repeated branching. p130Cas protein acts as an adapter, forming complexes with various proteins through integrin and growth factor signaling, regulating essential cellular processes. This study found that p130Cas is expressed in ductal epithelial cells of the submandibular gland (SMG), and its deficiency leads to immature development of granular convoluted tubules (GCT) and downregulated AR signaling.

Summary: The uptake and potential intergenerational transfer of Cry1Ab insecticide from genetically engineered maize to the predator Harmonia axyridis were investigated. Cry1Ab concentration was significantly lower in the herbivore Rhopalosiphum padi and the predator H. axyridis compared to GE maize. Cry1Ab did not affect the performance or cause any pathological changes in H. axyridis, suggesting that the detected route of exposure is unlikely to impact the biological control of this predator in agroecosystems.

Summary: For the past 80 years, tilapia have been globally translocated for aquaculture, with production recorded in over 124 countries. Of the 7 million tonnes of tilapia produced, 79% comes from countries outside their natural range. Tilapias carry numerous parasites, and this review provides a summary of over 2500 host-parasite records and more than 820 recorded tilapia translocations. The study highlights the significant pathogens that pose a threat to tilapia health and identifies the risks of parasite translocation as aquaculture industries expand.

Summary: We conducted a detailed analysis of the brain anatomy of two species of saturniid moths, including larvae and adult males and females. 3D reconstructions based on high-resolution optical sections revealed that the brain neuropils of these species are virtually identical. Both species exhibit sexual dimorphism in adult individuals, with a male-specific assembly of enlarged glomeruli forming a macroglomerular complex. The neuropil architecture of saturniids is similar to that of other nocturnal moths, but significant differences were observed compared to diurnal lepidopteran species, including in the mushroom body and optic lobes.

Summary: Although interest in Acanthocephala is limited to a small community of researchers globally, this opinion article highlights their potential as model organisms for studying parasite biology, evolution, and ecotoxicology. Their ancestral relationship with rotifers makes them ideal for exploring the origins of parasitic lifestyle and understanding behavioral manipulation. Additionally, their ability to accumulate contaminants offers opportunities for monitoring and mitigating the impact of pollutants on aquatic fauna and developing environmental parasitology. However, further research is needed to connect fragmented knowledge and expand the taxonomic coverage of data.
