Calprotectin (CALP) and B-Cell Activating Factor (BAFF) are inflammatory biomarkers having a role in the gastrointestinal neutrophilic response to bacterial infection. The study was designed to assess serum CALP and BAFF as inflammatory biomarkers in H. pylori infection and peptic ulcer patients. The current study comprised 112 people, including 62 H. pylori-infected patients (34 men and 28 women) who were clinically diagnosed with H. pylori infection via testing positive for the H. pylori stool antigen test; they were compared to a control group of 50 healthy people (34 men and 16 women) who were age and gender-matched to H. pylori-infected patients. The serum level of CALP and BAFF were assayed using the ELISA technique. The biochemical parameters were statistically compared between patients and controls by unpaired Man-Whitney U t-test and Receiver Operating Characteristic (ROC) curve analysis. There was a significant elevation of serum CALP in H. pylori-infected patients [116.4(120.7), p=0.0132] in comparison to healthy controls [99.50(115.8)]. Similarly, there was a significant elevation of serum BAFF concentration in H. pylori-infected patients [485.7(367.1), p=0.0014] in comparison to healthy controls [444.5(513.0)]. The ROC curve analysis suggests serum CALP and BAFF as reasonable inflammatory biomarkers for H. pylori infection with statistically significant (p=0.0135, p=0.0015) area under the ROC curve of (0.6361, 0.6748), respectively. CALP and BAFF are potent inflammatory biomarkers involved in the development and etiology of H. pylori infection. Serum CALP and BAFF levels could be used as biomarkers for chronic inflammation induced by H. pylori. CALP and BAFF biomarkers can be combined to diagnose and predict the prognosis of H. pylori infection.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72735214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, a total of 21 LAB strains and 36 yeast strains were isolated from different traditional sourdough. Dough fermentation were assessed by monitoring physicochemical parameters including, titratable acidity, decrease of pH and lactic acid, ethanol and CO2 production. A total of six yeasts and four LAB were selected for their technological performances. Morphological, physiological and biochemical identiﬁcation performed using API identification kits conﬁrmed that these strains belonged to Saccharomyes cerevisiae, Candida humilis and Saccharomyces exiguus species, and Lactobacillus plantarum and Lactobacillus casei species for yeasts and LAB respectively. The yeast S3-L2 and the LAB OD-BL5 strains exhibited the best performances among the selected ones; S3-L2 yeast strain were able to produce ΔV=23mL of CO2 and showed the highest values of ethanol and biomass production (2.87 g/L and 1.25 10^9 UFC/mL, respectively). Whereas OD-BL5 LAB strains produced 13.9 g/L of lactate in dough. These findings lead to consider these two strains very good candidates for the formulation of an effective mixed starter for bread preparation. Subsequently, sensorial analysis results showed that bread prepared using mixed starter No. 24 composed of the two selected species exhibited better exterior appearance, golden and crispy crust, large volume and honeycomb crumb, compared to the control.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83997126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study is a six-month observational prospective longitudinal evaluation of 185 obese individuals with T2DM. They were initiated on Dulaglutide as an add-on drug with Oral Antidiabetic (OAD) or insulin therapy. General characteristics of the patients, glycated hemoglobin (HbA1c), blood glucose, lipid profile, and side effects profile were evaluated at the enrollment and the end of the study. The enrolled 185 obese patients with T2DM, had a T2DM duration (2 -14 years) and initial HbA1c range (6 - 19.5%), with different treatment modalities, including insulin, OADs, or both. The study showed a significant reduction in weight, HbA1c, and serum cholesterol, with minimal hypoglycemic events in 5% of patients (n=9). The gastrointestinal side effects were mild to moderate and self-limited in >96% of patients (n=178), while they were so severe in 4% (n=7) and caused discontinuation of Dulaglutide. Therefore, the insulin regimen was either stopped (n=28), changed (n=7), or reduced (n=9). No change on oral medications was performed in 141 patients.

In this study, the bacterial endophyte Colony Forming Units (CFU) were counted based on the most suitable dilution in petri dishes and expressed per g of wet weight of tuber tissue. The presence of bacteria was found mostly in the outer layer. A wide variety of endophyte species biodiversity was in Agria cultivar. To estimate the antagonistic effect of potato associated endophytic bacteria, 115 bacterial isolates were evaluated by dual culture method against main soil-borne potato pathogens Fusarium oxysporum, Rhizoctonia solani, Verticillium dahliae, Streptomyces scabies and Ralstonia solanacearum. Endophyte strains were identified based on physiological, morphological and chemical characteristics and the 16S rRNA gene sequence analysis. The highest degree of the inhibitory activity in all layers of potato cultivars was related to Bacillus subtilis, Bacillus mojavensis and Klebsiella variicola. Antagonistic activity of endophytic bacteria against the pathogens was significantly higher (p<0.01) in the examined strains from the outermost layer of tuber peel and decreased progressively toward the center of the tuber. In this research, Klebsiella variicola was reported as endophyte bacteria in the four commercial potatocultivars mentioned above, for the first time.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88607004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Failure in balancing the up-regulation and down-regulation causes excessive production of proinflammatory cytokines in the fight against SARS-CoV2 virus infection, leading to lung damage and acute respiratory distress syndrome; in addition, high levels of IL-6 can activate the clotting pathways and vascular endothelial cells, which can inhibit blood circulation and heart muscle function and cause pulmonary, kidney, and liver fibrosis. Hydroxysafflor Yellow A (HSYA) is a compound that has been shown to reduce tissue lung damage through Toll-Like Receptor (TLR) 4, inhibits phosphorylation of the NF-κB pathway, and plays a role in balancing the up-regulation and down-regulation of inflammatory cytokines. This review of literature discusses the ability of HSYA to reduce inflammation that causes pulmonary cell and tissue damage. HSYA can inhibit the activation of the NF-κB signaling pathway and suppress the binding of the TGF-β1 promoter. This molecular mechanism can reduce lung damage by attenuating the inflammatory response by inhibiting the TLR 4-dependent pathways that can improve the condition of mice affected by pulmonary fibrosis, including inflammation that leads to vascular tissue repair. The molecular mechanism of HSYA can inhibit inflammatory mechanisms in lung injury, vascular tissue damage, and liver and kidney fibrosis. Therefore, this literature review can be used as a reference for in vivo research and clinical trials for further research on the ability to heal patients with cytokine storm that causes cardiovascular tissue damage and lung injury in patients infected with SARS-CoV-19.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91524521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is relevant the search for drugs with a metabolically justified protective effect. Edaravone (Eda) is widely used for treating ischemic stroke but its biochemical effects in intracerebral hemorrhage (ICH) associated with T2DM is not still confirmed. The aim of the study was to assess the impact of Eda on the markers of oxidative modification of proteins (OMP), such as advanced oxidation protein products (AOPP), neutral and basic carbonyls (PC370 and PC430), advanced glycation end products (AGE) and ischemia modified albumin (IMA) as well as on the activity of matrix metalloproteinases MMP2/MMP9 (gelatinases) in rats with experimental T2DM after collagenase-induced ICH. Metformin was used as a comparative drug. The data obtained indicate that ICH in diabetic rats is accompanied by an increase in AOPP, PC370, AGE, and mature forms of both gelatinases. On the contrary, IMA and proMMP9 were below normal level after ICH. Both studied drugs decreased the OMP markers to the levels of intact rats or lower, and Eda show a more potent effect. Besides, Eda significantly decreased the activity of MMP9 and changed progelatinases activity. We conclude that Eda has a perspective to be useful in the treatment of comorbid brain hemorrhage in T2DM due to inhibiting of oxidative stress and modulation of gelatinases activity.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83373279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Natural compositions are considered as substitutes of synthetic preservatives in products, which have been extensively employed. The aim of present research is to investigate the impact of Ferulago Angulata Essential Oil (FAEO) as an antimicrobial and antioxidant factor for preserving of dry fermented sausages throughout storage. Initially, FAEO was extracted using microwave assisted hydrodistillation and its components were identified by gas chromatography-mass spectroscopy. Fermented sausages were treated by starter culture (Biobak K) and FAEO at various concentrations (0, 400, 800 and 1000 ppm). Afterwards, tests such as pH, moisture, thiobarbituric acid, texture, microbial growth, electron microscope images, and sensory evaluation were conducted during storage (28 d). The high levels of bioactive compositions such as limonene (30.71%) and α-pinene (19.02%) were indicated in FAEO. The results illustrated that pH and moisture of all fermented sausages were within the standard range during storage. At different concentrations, FAEO significantly decreased thiobarbituric acid of treated samples compared to control (p<0.05). Furthermore, FAEO was able to improve cohesiveness and elasticity of fermented sausages, which were also visible in electron microscope images. Antimicrobial feature of FAEO was distinguished by evaluating microbial attributes (total viable count, lactic acid bacteria and yeast) in fermented sausages. Ultimately, FAEO at 800 ppm concentration was detected as a promising and appropriate natural preservative during storage in fermented sausages.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80783603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
