Summary: Centropomus undecimalis (common snook) and Centropomus parallelus (fat snook) have a wide distribution from southern Florida to southern Brazil, and their genetic diversity among populations highlights the need for targeted conservation efforts. Microsatellite markers proved effective in assessing genetic variability and contributed to understanding population genetics in these snook species. Despite not being classified as endangered, genetic differences among populations emphasize the importance of considering population-level characteristics in conservation strategies. Our study demonstrates the significance of microsatellite markers in informing conservation efforts for common snook and fat snook.

Summary: This study analyzed the efficiency of using lambari Deuterodon iguape as a live bait compared to traditional artificial bait in sea bass fishing and demonstrated its viability. The results showed that lambari Deuterodon iguape is as efficient as artificial bait for bass fishing in inland waters and can be an economic alternative. Moreover, using live bait of native species can contribute to employment and income generation.

Summary: This study introduces a combined method that can detect the activity of chloroacetate esterase and label the components of a specific tissue microenvironment simultaneously, using formalin-fixed, paraffin-embedded specimens. The chromogenic detection technique allows for the identification of molecular targets within and outside mast cells, which offers novel possibilities for understanding the histoarchitectonics of organ-specific mast cell populations, investigating the functional significance of chloroacetate esterase, and characterizing the immune landscape of the tissue microenvironment.

Summary: Rodlet cells are unique cells found in marine and freshwater fish tissues, and there are still many unknowns about their origin and function. This review provides new evidence on the relationship between rodlet cells and metazoan parasites, as well as a protozoan infecting organs of different fish species, and updates our understanding of the origin, structure, and function of these intriguing fish cells.

Summary: The fat body in insects is an equivalent of vertebrate adipose tissue and liver, playing important roles in metabolism, storage, immune system, and detoxification processes. In this study, we investigated the accumulation of reserve molecules in the fat body of Bombyx mori at different developmental stages, and found that glycogen, lipid, protein, and uric acid content gradually increase during the larval stage and decrease during the pupal stage. Further research is needed to explore the underlying functions of fat body formation throughout development, and it can serve as a model for studying metabolic disorders and immune diseases.

Summary: This study analyzed the human scapholunate interosseous ligament (SLIL) using various histological methods and found that it is heterogeneous, consisting of at least six different regions that resemble human cartilage, ligament, and other anatomical structures. The study proposes a novel molecular classification of the different regions of the SLIL based on histological, histochemical, and immunohistochemical analysis. These findings contribute to understanding why certain zones of the SLIL are more prone to damage and have specific regeneration potential.

Summary: This study examines the impact of metallic smoke released by steel industries on soil and aquatic ecosystems, as well as its effects on metal bioconcentration, antioxidant responses, and tissue histopathology in fat snook fish. The findings show that different organs have different levels of metal bioconcentration, with gills being the most affected. Antioxidant responses also vary in different organs, indicating potential risks to fish health.

Summary: This study aimed to determine the effects of the new succinate dehydrogenase inhibitor (SDHI) fungicide, flubeneteram, on reducing stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The study found that flubeneteram significantly inhibited the SDH enzymes of Pst and primed wheat for defense against Pst infection by upregulating pathogenesis-related genes (PR1 and PR2). These findings suggest that flubeneteram could be an effective fungicide for managing stripe rust.

Summary: Three types of glandular trichomes are developed on the flowers and leaves of Millingtonia hortensis, each with specific ultrastructural traits. These trichomes contain different chemical substances and play distinct roles in attracting pollinators and protecting vegetative shoots. GC-MS analysis identified seventeen compounds in the internal pool of metabolites, including alcohols, terpenes, and benzenoids.

Summary: This study focuses on the microscopical, chemical, and ultrastructural features of the floral secretory tissues in two species of fly-pollinated plants, Echidnopsis cereiformis and Stapelia scitula. It compares these features with previously studied orchid species and notes significant differences in secretion between the two plant families. The presence of a prominent periplasmic space in the epidermal cells of Stapelia scitula is particularly noteworthy and may have taxonomic significance.

Summary: The reproductive biology of Centropomus parallelus was studied in estuarine and coastal waters in Southern Brazil, with males dominating in smaller length-classes and females in larger length-classes. The total length at maturity was found to be 180 mm, representing 29% of the maximum length recorded. The study's findings can contribute to sustainable fisheries management practices.

Summary: This paper discusses the use of the terms "venom" and "poison" in the context of integrative biology, with a focus on animal behavior and natural history. The differences in secretion perspective are highlighted, particularly in relation to reptiles and amphibians, to justify the use of the two terms based on biological and behavioral distinctions.

Summary: Toads are considered poisonous animals that rely on cutaneous poison glands for defense. This study compared the skin morphology, poison gland quantity, water resistance, and water uptake rates of Rhinella icterica from the Atlantic rainforest and Rhinella jimi from the Brazilian Semiarid Caatinga. Rhinella jimi exhibited higher number of poison glands with hydrophilic content, thicker skin, and unique hydration behavior, possibly suggesting a role of poison glands in water balance in addition to chemical defense.

Summary: Chondroitin sulfate (CS) has been found to have therapeutic effects in an experimental model of bile duct ligation. CS reduces collagen content and increases liver parenchyma content, and can alter the hepatic collagen III/I ratio. Additionally, CS reduces cell death indicators and promotes regeneration. Therefore, CS has potential hepatoprotective action in fibrogenesis induced by bile duct ligation.

Summary: This study aimed to investigate the extent to which alkaloid sequestration and modification depend on alkaloid availability and/or sequestration mechanism. The results showed that the quantity of alkaloids accumulated in the liver and skin increased with higher doses of alkaloids. Moreover, a previously unknown example of alkaloid modification in poison frogs was identified.
