The disease has a multifactorial etiology that includes anatomic, environmental, genetic, infectious, metabolic, nutritional, and most importantly socio-economic factors. It is caused by a biochemical imbalance in urine between stone-forming inhibitors and promotors in a process known as lithogenesis. The mechanisms underlying the formation and development of urinary stones are not fully understood, but it can be said that they generally begin by increased urinary supersaturation of lithiasis promoters in the urine, followed by nucleation and aggregation. Subsequently, the crystals combine with other crystals in solution to form agglomerates that accumulate in the kidney. Free radical-mediated oxalate-induced renal membrane damage promotes crystal retention at the surface of the renal papilla, as well as crystal nucleation at lower supersaturation levels. In addition, stone type identification is of great interest in guiding the physician to an effective diagnosis, which allows to determine the causes in order to treat the disease and prevent recurrence. In this context, this present study reviews current knowledge on the pathophysiological aspects of kidney stone formation as well as the type of stones.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41745801","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}

Skeels is an endemic species of west-central Morocco, which is characterized by a high diversity of morphological and genetic traits. It constitutes a natural resource for oleo-agro-sylvo-pastoral uses. All conservation and genetic breeding strategies aimed to domesticate argan require a good knowledge of the plant material. However, several studies focused on agronomical, morphological, phytochemical, and molecular characterization, while the cytogenetic aspects were less investigated. The objective of this work is to identify the chromosome number and ploidy level on the national argan collection at the Agadir Regional Agronomic Research Center, Morocco. The determination of the chromosome number was carried out on root tips of germinated seeds collected from five trees genotypes selected on various morphological aspects. As a result, chromosome count on active root tip cells showed variation in the number (2n = 20; 2n = 22; 2n = 24) with a stable ploidy level (2n = 2x) that is confirmed by flow cytometry. These results combine two previous findings (2n=20, 2n=24) and reveal a third existence of twenty-two chromosome. As a conclusion, A. spinosa has three chromosomal numbers which represent the genetic diversity of the chromosomal number that this species exhibits. More studies are required to explain this variation on chromosome numbers for future breeding programs and to avoid incompatibilities.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46596171","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}

In this study, twenty-six strains of actinomycetes were isolated from rhizospheric arid soil of the halophyte Atriplex halimus L. ῾Guettaf’ in Biskra province, Algeria. The six isolates that have inhibited at least three phytopathogenic fungi among the five tested (Fusarium oxysporum, Alternaria alternata, Fusarium solani, Aspergillus flavus and Botrytis cinerea) were selected, and have been tested in vitro against phytopathogenic bacteria (Pectobacterium carotovorum and Streptomyces scabies). They were also evaluated for their ability to hydrolyze phosphate, elaborate siderophores, produce indole-3-acetic acid (IAA), and to antagonize S. scabies in vivo (on radish seedlings). Based on the physicochemical analyses, soil samples were categorized as alkaline and extremely-saline. The antagonism results revealed varying antifungal potential among the selected isolates (Act11, Act16, Act17, Act18, Act23 and Act24), about 50% were able to inhibit the growth of F. solani and A. flavus, followed by 33.33% of those having antagonized F. oxysporum, while A. alternata was found to be the most sensitive. Only Act18 has antagonized S. scabies in vitro with an inhibition diameter zone of 19 ± 0.41 mm. However, in vivo trials showed that four isolates have counteracted S. scabies. Among them, Act18 and Act24 have significantly and positively affected the root surface (P = 0.0062) and prevented common scab. IAA was detected in all selected isolates with Act24 being the highest producer (77.45 μg mL−1). Additionally, degradation ability revealed that four isolates were able to hydrolyze phosphate while three exhibited the capacity of elaborating siderophores. The six isolates were assigned to Streptomyces genius according to their morphological, physiological and chemotaxonomical traits. Based on this study, Streptomyces sp. Act18 and Streptomyces sp. Act24 that tolerate 7.5% NaCl concentration, prevent common scab and exhibit some plant growth attributes, may be considered as promising biocontrol agents to be applied in arid and saline soils.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46146019","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}

The study was carried out on four representatives of the genus Malus: M. niedzwetzkyana Borkh., M. baccata ‘Pendula’, M. domestica ‘Eliza Rathke’, M. domestica ‘Renet Simirenko’. The influence of drought on the size of the mesophyll of the leaf plate and the number of stomata along the stretch from June to August was studied. The cell circumference of the sclerenchyma ranged from μm in 27.33 (M. niedzwetzkyana) to 81.92 μm (in M. domestica ‘Elise Rathke’). The number of stomata varied from 214.0 units in (M. domestica ‘Renet Simirenko’) to 304.0 units in (M. baccata ‘Pendula’), length from 11.6 μm (M. baccata ‘Pendula’) to 28.63 μm (M. domestica ‘Elise Rathke’), width from 9.4 μm (M. domestica ‘Elise Rathke’) up to 21.8 μm (M. domestica ‘Elise Rathke’) μm. The length of the trichomes varied from 409.92 μm (M. domestica ‘Renet Simirenko’) to 745.09 μm (M. niedzwetzkyana). Also, the anocytic stomatal type, the number, different stomata and trichomes, the presence of wax on the cuticle, and the found druses of calcium oxalate in M. baccata ‘Pendula’, can be important for systematic phylogeny.

It contains vitamins and vital nutrients that are essential for good health. This study was conducted to determine the effect of magnetization of irrigation water on the growth, yield and nutritional qualities of tomatoes under deficit irrigation. Tomato seeds (‘Roma VF’ and ‘UC 82B’ varieties) were planted in 96 buckets (11 liters capacity), 48 buckets for magnetized water (MW) and 48 buckets for non-magnetized water (NMW), grown in a greenhouse and harvested 82 days after planting. The irrigation water was treated with 30 pieces of 10×25×50 mm neodymium magnets (1.2 Tesla). The tomato plants were subjected to deficit irrigation to determine the effect on the performance of tomatoes at 100% (1 liter), 80% (0.8 liters), 60% (0.60 liters) and 50% (0.50 liter) water requirement. Each treatment was replicated 6 times for both MW and NMW. The MW increased the growth of ‘Roma VF’ and ‘UC 82B’ varieties by 5.44-38.10% and the stem girth by 21.13-49.01%. MW increased the yield of ‘Roma VF’ variety by 110.00%, 36.00%, 6.26% and 24.00% for 100%, 80%, 60% and 50% of water application, respectively but increased the yield of ‘UC 82B’ variety by 56.52% for 100% water application. MW also improved vitamin A and C content by 7.89-27.94% and 0.45-19.06%, respectively.
