Such information is nonetheless essential for a better understanding of the factors and processes shaping scorpion morphology. In this work, we investigated sexual size dimorphism in Buthus tunetanus, a common scorpion species in Tunisia. Using morphometric data on a sample of 100 females and 142 males, we assessed sexual differences in body parts and investigated allometric relationships. Results showed significant sexual size dimorphism in weapon systems, namely the metasoma and chelae. More specifically, there was male-biased dimorphism in metasoma size but female-biased dimorphism in chela size. Increased body size was associated with an exaggerated increase in metasoma size in males and chela size in females. These patterns are in agreement with those previously reported in other scorpion species and highlight the roles of sexual differences in mating behavior and ecological requirements in shaping the morphology of weapon systems in scorpions.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"89 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the relationship between the m6A demethylase ALKBH5 and porcine growth and development as well as pathogenic microbial infection still remains unknown. Here, the expression levels of ALKBH5 in tissues of Meishan pigs at different stages from birth to adulthood were detected by qPCR. Then, we analyzed the expression change of ALKBH5 protein in IPEC-J2 cells after pathogenic infection (PEDV, TGEV, PCV2 and E. coli F18). Results showed that ALKBH5 was expressed in different tissues of Meishan pigs. The expression levels were high in spleen, lung and intestinal tissues (duodenum, jejunum and ileum). Besides, similar expression patterns were observed in specific tissues at different developmental stages. In addition, the expressions of ALKBH5 in the intestinal tissues (duodenum, jejunum and ileum) were significantly lower in the adult stage than in the birth and juvenile stages (P < 0.05). ALKBH5 protein was significantly up-regulated in IPEC-J2 cells with PEDV or PCV2 infection, but not TGEV. After E. coli F18 infection, the expressions of ALKBH5 mRNA and protein were both significantly down-regulated. Our findings indicated that ALKBH5 expression is closely related to the intestinal resistance to pathogenic infection in piglets. Therefore, it is necessary to further verify the function and mechanism of ALKBH5 gene at the cellular and individual levels in the future, in order to identify it as an important candidate marker for pig disease resistance breeding.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"26 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rutin, a natural product extracted from tobacco leaves and tomatoes, has excellent anti-inflammatory and antioxidant properties in vivo, but its ameliorative effect on T. gondii infection-induced brain tissue damage remain unknown. In this study, mice were acutely infected with RH virulent strains of T. gondii, then treated with 0–50 mg/kg of Rutin. Results showed that Rutin significantly reduced the number of abnormal morphological neurons in the hippocampal region of brain tissue, decreased the concentration of Iba-1, the biomarker of microglia which indicates increased tissue damage and inflammation in the brain; decreased the level of inflammatory factors (TNF-α, IL-6 and IL-1β) in serum and increased the content of antioxidant enzymes (GSH and SOD) in brain tissue; and decreased the enrichment of oxidation products MDA. Results showed significant downregulation of key proteins in the two inflammation-related pathways, TLRs/NF-κB, P2X7R/NLRP3. While the proteins in the antioxidant-related pathways were noticeably upregulated in the T. gondii-infected brain tissue with Rutin treatment. These findings suggest that Rutin ameliorates T. gondii-induced brain tissue damage, may involving in inhibiting the TLRs/NF-κB and P2X7R/NLRP3 inflammatory signaling pathways, and activating the PI3K/AKT/Nrf2/HO-1 antioxidant pathway. The findings could provide some theoretical support for Rutin’s potential therapeutic use in treating T. gondii-related brain damage in the future.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"7 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding nutrient metabolism, the liver shows a quick response to nutrient status fluctuation, such as feeding and fasting. Indeed, fasting is a powerful tool to uncover the molecular mechanism through which the expression of hepatic genes is regulated. The most widely applied approach to test gene expression at the RNA level is relative quantitative polymerase chain reaction (qPCR) using stably expressed genes as an internal reference. In this study, we leveraged transcriptomic analysis to screen the hepatic genes whose expression levels were stable in response to fasting. Our data suggested that expression levels of several well-known reference genes such as beta-actin and Eef1a1 are dramatically altered upon fasting. Further assessment indicated that Itm2b is the most stably expressed hepatic gene showing no alteration to fasting. Compared to beta-actin and Eef1a1, similar results and conclusions as transcriptomic analysis were obtained using Itm2b as an internal reference in qPCR when we assessed the effect of fasting on the expression of genes involved in peroxisomal fatty acid oxidation, fatty acid synthesis, and gluconeogenesis.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"39 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives of this research were to provide the first baseline survey of epibenthic communities in the Mekong estuaries and to describe more precisely the relationships between epibenthic characteristics and environmental parameters. In total, seven major taxa, including Bivalvia, Decapoda, Gastropoda, Isopoda, Molpadida, Stomatopoda, and Xiphosura were recorded in this estuarine system. The abundances of the epibenthic invertebrates range from 48 to 176 inds/1000 m2. Decapos always occupy the highest numbers with a percentage ranging from 86‒95%. There are 24 decapod species were recorded in this study with the following as dominant families Palaemonidae, Penaeidae, and Paguridae. Our findings highlight that the diversity of epibenthic communities, particularly for decapods, is notably high; however, the epibenthic density is considerably low. Epibenthic density and diversity were significantly correlated with salinity, TDS, depth, and pH but also other factors may play a role. The assessment of epibenthic assemblage diversity and its correlation with environmental factors holds significant importance in the formulation of conservation strategies.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"24 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the efficacy of different strains [Bti ATCC 35646 (wild-type strain), Bti pHT315, and Bti pHTppk (mutant strain)] of Diptera-targeted Bacillus thuringiensis subsp. israelensis (Bti) and toxins (spore/crystal mixtures) obtained from these strains against the 4th larval stage of T. wilkinsoni under laboratory conditions. T. wilkinsoni eggs were collected from pine trees at Ondokuz Mayıs University in Samsun, Turkey, in 2022. Pine needles were contaminated with bacterial strains of different concentrations (1 × 107, 1 × 108, 1 × 109 cfu/mL) in 5 mL and toxins in different concentrations (0.15, 0.3, 0.6, 1.25, 2.5, 5 mg/mL) in 2 mL. Larvae were placed in containers with 30 larvae in each group and were observed for 25 days. As a result of the study, Bti ATCC 35646 with 63.4% mortality and the lowest LC50 value of 1.2 × 109 cfu/mL among the three strains of Bti and Bti pHTppk with 76.7% mortality and the lowest LC50 value of 1.2 mL among the toxins from the Bti strains had found to be virulent for T. wilkinsoni.

Wild olives constitute a priceless reservoir of genetic diversity which has great value for olive breeding and conservation programs. However, global climate changes especially global warming is expected to threaten olive cultivation in future causing large economic loses in the region. Therefore, knowledge about distribution and abundance of wild olive populations is important to maximize their conservation, safeguard, and exploitation. Muğla province, where the wild olives make up an important part of the vegetation, is one of the main olive producing area in Turkey with many towns and villages dependent on the olive. In this study, our aim is to examine the current geographical distribution and density of wild olive populations in this province and the 82 islands around its coast. The results demonstrated that young olives, which show good adaptation to region, just have started to expand to the higher parts of the Kavaklıdere district. In addition, in most of the islands wild olives are preserved in their undisturbed natural habitats where they exist as small groves or scattered plants. The results of this study provides important insights for the conservation of wild olive genetic resources. The data reported here, are based on actual field data thus the geographic coverage tends to be complete and consistent.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"4 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
