Abstract:
Abstract The Snail family of transcriptional regulators consists of three highly conserved members. These proteins regulate (repress) transcription via the recruitment of histone deacetylases to target gene promoters that possess the appropriate E-box binding sequences, specifically with GC-rich central dinucleotides. Murine Snai1 is required for mouse development while Snai2 deficient animals develop normally but have been reported to have thymic T cell deficiencies. Less is known about the third member of the family, Snai3. To investigate the function of Snai3, we generated a conditional knockin mouse. Utilizing Cre-mediated deletion to facilitate the ablation of Snai3 in T cells or the entire animal, we found little to no effect of the loss of Snai3 suggesting possible compensation with another family member. To test this, we created Snai2/Snai3 double deficient mice. The developmental consequences of lacking both of these proteins was manifested in stunted growth, a paucity of offspring including a dramatic deficiency of female mice, an overgrowth of the eyelids and impaired immune cell development particularly within the lymphoid lineages.

Abstract:
For many years Poland has been a highly recognized producer and supplier of Cornu aspersum (Cornu aspersum aspersum, Cornu aspersum maxima) and Helix pomatia snails in European markets. Exports include both live snails and snail-derived food products such as snail meat and eggs. Slime, used in pharmaceutical and cosmetic industries, is another economically significant snail-derived product. This paper presents standardized terminology for farm snails and outlines regulations concerning snail farming, trade, processing plants and snail meat obtained. The current results of microbiological studies of snail meat obtained in Poland are shown as well. The analysis conducted in this paper indicates the need to clarify legislation, especially with regard to snail farming, and to elaborate regulations on snail meat processing....

Abstract:
The tropical parasitic disease schistosomiasis haematobium requires the snail vector Bulinus truncatus to successfully complete its life cycle. While in the snail, the parasite exists as a cercarial producing sporocyst. The infection of snails by the parasite is very specific, different subpopulations (strains) of parasites are not always compatible with snails from different geographic regions. It is not always known if the incompatibility is due to failure of penetration of snails by parasites or to subsequent destruction of sporocysts by infected snails. In these experiments, sporocysts from compatible sporocyst-snai1 infections were surgically transplanted into snails not compatible with the parasite.Egyptian snails (B. truncatus) which had been infected with the Egyptian strain of Schistosoma haematobium were dissected after five weeks. Sporocysts were removed from the hepatopancreas and surgically implanted into B. truncatus snails from Egypt (compatible), Morocco and Niger (incompatible). After four days, these snails were dissected and the transplanted sporocysts were prepared for electron microscopy. Each sample was also tested for glycogen contents by the Thiery Silver test.

Abstract:
Cabbage (Brassica oleracea capitata) is an important commodity in the Karangreja area of Purbalingga District. The crop is attacked by land snails. The objectives of this study were to: 1) identify the land snail species that attack cabbage crops; 2) ascertain the snail attack symptoms; 3) ascertain the snail population and attack intensity; and 4) show where snails are found in cabbage fields. The Purbalingga Regency's Karangreja Sub-district served as the site of the survey investigation. The Indonesian Institute of Sciences' Research Center of Biology, Laboratory of Zoology, identified land snails. The study was from February until April 2017. The findings indicated that Bradybaena similaris was a species of land snail. The snail attack was characterized by circular holes in the center of the leaves. The snail population ranged from 8.21 to 44.90 individuals, with varying assault intensities of low (21-40%) and medium (41-60%). The snail is distributed in a clumped pattern. We concluded that Bradybaena similaris snails are an important pest of cabbage plants.

Abstract:
The influence of population density on some aspects of the reproductive biology of the snail Bradybaena similaris was studied. Molluscs were maintained under 0.2 (isolated), 0.3, 0.6, 1.0, 1.3 and 1.7 snail/m² densities. The animals maintained under 0.3 and 0.6 snail/m² showed the lowest numbers of eggs laid/snail, being the highest value observed to the 1.7 snail/m². The hatching of the snails maintained under 0.3 snail/m² density, begun at the 21st day after laying, and the maximum time required to the hatching was 36 days was observed to the eggs came from snails maintained under the densities 0.6, 1.0, 1.3 snail/m², respectively. The highest percentage hatchability (55.56%) was observed to isolated snails. The galactogen content in the albumen gland did not seem to accompany the alterations occurred in the reproduction of B. similaris in response to the different population densities.

Abstract:
The effect of temperature (19–36 °C) and snail host density (0.014–10 snails/1) on the snail-finding capacity of Echinostoma caproni cercariae is described. The initial swimming speed increased whereas the length of the infective period decreased with increasing temperature. The combined effect resulted in the E. caproni cercarial snail-finding capacity being temperature independent in the range 19 to 36 °C at a snail density of 0·014 snails/1. A moderate temperature dependency was, however, seen at a lower snail density. The cercarial snail-finding capacity was snail-host density dependent in the density range 0.014 to 1 snail/1. The findings from this study show that a relatively low and biologically realistic snail host density must be used in experimental studies if realistic estimates of the dynamics of cercarial transmission are to be obtained.

Abstract:
Snail control to complement mass drug administration is being promoted by the World Health Organization for schistosomiasis control. Oncomelania hupensis quadrasi, the snail intermediate host of Schistosoma japonicum in the Philippines, has a very focal distribution; thus, scrutinizing baseline data and parameters affecting this distribution is very crucial. In this study in Gonzaga, Cagayan, Philippines, snail habitats were surveyed, and the various factors affecting the existence of the snails were determined. Malacological surveys and the mapping of sites of perpetual wetness in five endemic and five neighboring non-endemic barangays were conducted. Environmental and physicochemical factors were also examined. Maps of both snail and non-snail sites were generated. Of the fifty sites surveyed, O. h. quadrasi were found in twelve sites, and two sites yielded snails that were infected with S. japonicum cercariae. Factors such as silty loam soil, proximity to a snail site, water ammonia, and soil attributes (organic matter, iron, and pH) are all significantly associated with the presence of snails. In contrast, types of habitats, temperatures, and soil aggregation have no established association with the existence of snails. Mapping snail sites and determining factors favoring snail presence are vital to eliminating snails. These approaches will significantly maximize control impact and minimize wasted efforts and resources, especially in resource-limited schistosomiasis endemic areas.

Abstract:
The land helix, or snail, has been used in medicine since antiquity and prepared according to several formulations. This historical report traces the understanding of their properties from the time of Hippocrates, who proposed the use of snail mucus against protoccle and Pliny who thought that the snail increased the speed of delivery and was “a sovereign remedy to treat pain related to burns, abscesses and other wounds”, Galien recommended snails against hydrops foetails. In the 18th century, various snail “preparations” were also recommended for external use with dermatological disorders and internally for symptoms associated with tuberculosis and nephritis. Surprisingly, the 19th century saw a renewed interest in the pharmaceutical and medical use of snails with numerous indications for snail preparations. This interest in snails did not stop at the end of the 19th century. The 1945 edition of Dorvault devotes an entire paragraph to snails, indicating that the therapeutic usage of snails was still alive at that time. Recently the FDA has also shown an interest in snails. Ziconotide (SNXIII), a synthetic peptide coming from snail venom, has been under FDA review since 1999. Pre-clinical and clinical studies of this new drug are promising.

Abstract:
Renal cell carcinoma (RCC) is the deadliest urological neoplasm. Up to date, no validated biomarkers are included in clinical guidelines for the screening and follow up of patients suffering from RCC. Slug (Snail2) and Snail (Snail1) belong to the Snail superfamily of zinc finger transcriptional factors that take part in the epithelial–mesenchymal transition, a process important during embryogenesis but also involved in tumor progression. We examined Slug and Snail immunohistochemical expression in patients with different stages of renal cell carcinomas with the aim to investigate their potential role as staging and prognostic factors. A total of 166 samples of malignant renal cell neoplasms were analyzed using tissue microarray and immunohistochemistry. Slug and Snail expressions were evaluated qualitatively (presence or absence), in nuclear and cytoplasmic cell compartments and compared in relation to clinical parameters. The Kaplan–Meier survival analysis showed the impact of the sarcomatoid component and Slug expression on the survival longevity. Cox regression analysis separated Slug as the only independent prognostic factor (p = 0.046). The expression of Snail was associated with higher stages of the disease (p = 0.004), especially observing nuclear Snail expression (p < 0.001). All of the tumors that had metastasized showed nuclear immunoreactivity (p < 0.001). In clear cell RCC, we showed a significant relationship between a high nuclear grade and nuclear Snail expression (p = 0.039). Our results suggest that Slug and Snail could be useful immunohistochemical markers for staging and prognosis in patients suffering from various RCCs, representing potential targets for further therapy strategies of renal cancer.

Abstract:
Freshwater snails are intermediate hosts for several snail-borne diseases affecting humans and animals. Understanding the distribution of snail intermediate hosts and their infection status is very important to plan and implement effective disease prevention and control interventions. In this study, we determined the abundance, distribution, and trematode infection status of freshwater snails in two agro-ecological zones of Ethiopia. We sampled snails from 13 observation sites and examined them for trematode infections using a natural cercarial shedding method. A redundancy analysis (RDA) was used to examine the relationship between snail abundance and environmental variables. Overall, a total of 615 snails belonging to three species were identified. Lymnea natalensis and Bulinus globosus were the dominant snail species, representing 41% and 40% of the total collection, respectively. About one-third of the total snail population (33%) shed cercariae. The cercariae species recorded were Xiphidiocercaria, Brevifurcate apharyngeate distome (BAD), Echinostome, and Fasciola. Snail species were found in high abundance in aquatic habitats located in the agricultural landscape. Therefore, land-use planning and protection of aquatic habitats from uncontrolled human activities and pollution can be considered as important strategies to prevent and control the spread of snail-borne diseases in the region.

Abstract:
The primary objective of my research was to test the hypothesis that the sperm release mechanism in the garden snail, Cantareus aspersus , is under nervous control. It was discovered that separate branches of the intestinal nerve innervate the seminal vesicle and the distal ovotestis duct, and sperm release from the seminal vesicle was achieved by electrical stimulation of this nerve. Stimulation of the penis nerve, right cerebropedal connective nerve, right mesocerebrum, visceral ganglion, and the everted reproductive organs elicited similar responses. Neurobiotin fills of the penis nerve (towards the penis) revealed putative sensory receptors at the base of the penis and within the genital atrium. Spermatophores from mated snails whose reproductive organs were treated with the local anaesthetic Lidocaine weighed significantly less than spermatophores from mated control snails, suggesting that mechanical stimulation during copulation triggers sperm release from the seminal vesicle.

Full text
Abstract:
Non-melanoma skin cancer (NMSC) is the most common human cancer worldwide. Squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) make up almost all NMSC. SCC usually arises from actinic keratosis (AK) as a result of exposure to sunlight. SCC and AK provide a useful clinical model to investigate changes involved in the progression of NMSC. This project examines the expression of Brm, Brg-1, Snail 1 and Snail 2 in the progression of NMSC. Brm and Brg-1 are subunits of the SWI/SNF chromatin-remodelling complex which is involved in regulating the access of cell machinery to DNA by altering the structure of chromatin. It has been suggested that loss of this function is involved in carcinogenesis as the cell is unable to access to DNA normally in order to repair mutations or activate apoptosis. The loss of Brm or Brg-1 has been described in several human cancers. Snail 1 and Snail 2 are zinc-finger transcription factors that are known for their role in epithelial to mesenchymal transition (EMT), a process vital to embryological development. Increased expression of these factors leads to a loss of cell-cell adhesion and a migratory phenotype and has been described in some human cancers. In this project, double-label immunohistochemistry was used to determine the relative expression of these proteins in human SCC, BCC, AK and normal skin. The expression of Snail was unable to be determined due to poor specificity of the antibodies used. The expression of both Brm and Brg-1 proteins was found to be dramatically and consistently decreased in SCC and BCC when compared to normal skin and AK. This loss of Brm and Brg-1 occured as the tumour progressed from benign AK to malignant SCC. This finding suggests that the loss of either Brm or Brg-1 constitutes a key step in carcinogenesis. The results of this study identify Brm and Brg-1 as putative tumour suppressors involved in the progression of non-melanoma skin cancer from benign to malignant.

Abstract:
Decision-support systems benefit from hidden patterns extracted from digital information. In the specific domain of gastropod characterization, morphometrical measurements support biologists in the identification of land snail specimens. Although snails can be easily identified by their excretory and reproductive systems, the after-death mollusk body is commonly inaccessible because of either soft material deterioration or fossilization. This study aims at characterizing Brazilian land snails by morphometrical data features manually taken from the shells. In particular, we examined a dataset of shells by using different learning models that labeled snail specimens with a precision up to 97.5% (F1-Score = .975, CKC = .967 and ROC Area = .998). The extracted patterns describe similarities and trends among land snail species and indicates possible outliers physiologies due to climate traits and breeding. Finally, we show some morphometrical characteristics dominate others according to different feature selection biases. Those data-based patterns can be applied to fast land snail identification whenever their bodies are unavailable, as in the recurrent cases of lost shells in nature or private and museum collections.

Abstract:
Background – GGolden apple snails (Pomacea canaliculata) are major pests in rice fields, causing significant challenges for farmers. Chemical controls leave sharp residual shells, increasing risks of leptospirosis and medical costs. While golden apple snails in Thailand are used for animal feed and wastewater treatment, they remain underutilized. Their shells, containing 20-50% chitin, can be extracted into chitosan-a non-toxic natural polymer suitable for Halal applications in health-related industries. Chitosan from snail shells offers an eco-friendly solution to reduce agricultural issues and promote sustainable economic opportunities for local communities. Purpose – This research aims to extract and characterize chitin from apple snail shells and evaluate its structural, chemical, and morphological properties. The study also examines contaminants like pesticide residues and heavy metals to assess its suitability for diverse applications. Design/methodology/approach – The extraction conditions included demineralization with 1 M HCl at 25 °C for 2 hours, deproteinization with 2 M NaOH at 25 °C for 2 hours. Fourier-transform infrared spectroscopy (FT-IR) confirmed functional groups, while Scanning Electron Microscopy (SEM) analyzed microstructure. Heavy metal and pesticide residues were assessed using AOAC methods. Findings – The resulting chitin yielded apploximately 40.77 % (w/w) of raw apple snail shells. The FT-IR absortion of light brown chitin powder showed 10 major characteristic peaks between 513 and 3430 cm-1. Metals like As, Cd, Pb, and Hg were undetected, except for 0.149 ppb Cu, and no pesticide residues were found. SEM analysis revealed that the particles had a polygonal shape with a rough surface texture. Research limitations – The extraction is limited by chitosan’s solubility in acid, requiring large shell fragments and higher solvent volumes, increasing cost and complexity. Originality/value – This study highlights that chitin extracted from apple snail shells offers a sustainable source for chitosan production. Utilizing this abundant but underused resource supports waste reduction and enhances agricultural productivity. Safety assessments, including tests for heavy metals and pesticides, confirm its suitability for applications in the food, pharmaceutical, and medical industries.

Abstract:
The Upper Delaware Scenic and Recreational River (UPDE) unit of the National Park Service partnered with the Academy of Natural Sciences of Drexel University (ANS) to perform a freshwater snail inventory within the park. ANS and UPDE teams conducted field research in July and August of 2022 and 2023 using a combination of kick-net sampling and hand-picking methods to determine the abundance and diversity of freshwater snail populations. Fifty-four sites were surveyed along the 73 miles of the Delaware River within UPDE and included cold-water and warmwater fisheries zones. In 2022, field collections occurred at 30 sites along the river edge from Hancock, New York, to the No. 2 railroad bridge near Mill Rift, Pennslyvania. In 2023, fieldwork occurred at 24 sites in relatively disturbed areas like river access points and boat launches, and within unique river features that were not sampled in 2022 (i.e., backwater, channels, and islands). Snails were identified using traditional morphological taxonomy and DNA barcoding of the CO1 (Cytochrome c oxidase I) gene. Additional environmental DNA (eDNA) was analyzed from water collected at ten eDNA Atlas Sites. Based on genetic analysis, 27 species of gastropods were identified, one of which is a non-native species, the Japanese Mystery Snail (Cipangopaludina japonica); previous studies found 18 species and identified the mystery snail as the Chinese (Cipangopaludina chinensis) (Evans 2004, Evans and Ray 2008, Evans and Ray 2010). There were more snails below the Cannonsville Reservoir influence in the warmwater zone. A better understanding of the snail community and the ecosystem has been gained with the results of this inventory, which will inform effective and responsible river management plans.
