In Vitro Antimicrobial Activity of Frankincense Oils from Boswellia sacra Grown in Different Locations of the Dhofar Region (Oman)
2020
Frankincense essential oils from Boswellia sacra have been commonly used to treat microbial infections from as early as the 11th century. The main feature of the plant is its gum resin, from which it is possible to obtain essential oils. In the present study, we focused on the comparative study of the oils extracted from the resins of three different Boswellia sacra cultivars (Najdi, Sahli and Houjri). From each of frankincense resin three successive essential oil samples (Grade 1, Grade 2, Grade 3) were obtained. Houjri gum resin gave the lowest percentage (5%) of total essential oil content but showed the maximum number of volatile components in all three grades. Najdi Grade 2 essential o…
La incidencia de las malas relaciones entre los progenitores a la hora de acordar el régimen de guarda y custodia compartida. Análisis de la reciente…
2018
The relationship that the parents have with each other is one of the factors to take into consideration when adopting or not the modality of shared custody and custody after a situation of family crisis. To deny the shared modality if there was no good relationship between the parents was the rule until relatively recent dates. With the entry into force of local laws as well as the change in jurisprudence, the tendency that remains is to consider that it will no longer be enough that there is this bad relationship but will have to be a situation of high confrontation so that this situation may be grounds for denial of the shared custody regime.
Peptides of the Constant Region of Antibodies Display Fungicidal Activity
2012
Synthetic peptides with sequences identical to fragments of the constant region of different classes (IgG, IgM, IgA) of antibodies (Fc-peptides) exerted a fungicidal activity in vitro against pathogenic yeasts, such as Candida albicans, Candida glabrata, Cryptococcus neoformans, and Malassezia furfur, including caspofungin and triazole resistant strains. Alanine-substituted derivatives of fungicidal Fc-peptides, tested to evaluate the critical role of each residue, displayed unaltered, increased or decreased candidacidal activity in vitro. An Fc-peptide, included in all human IgGs, displayed a therapeutic effect against experimental mucosal and systemic candidiasis in mouse models. It is in…
Smago metālu ietekme uz Armeria maritima augšanu in vitro apstākļos
2022
Antropogēnais smago metālu augsnes piesārņojums ir palielinājis interesi par smago metālu tolerantām sugām. Ir veikti pētījumi par A. maritima smago metālu toleranci un akumulāciju augsnē un hidroponiskajās sistēmās, savukārt trūkst informācijas par smago metālu ietekmi uz A. maritima augšanu in vitro apstākļos. Darba mērķis ir noskaidrot smago metālu ietekmi uz A. maritima augšanu in vitro apstākļos. Pētījumā izmantoja iepriekš in vitro audzētas A. maritima kultūras ievāktas no divām dažādām atradnēm – Vecdaugavas un Vakarbuļļiem. A. maritima audzēja in vitro Murashige&Skoog barotnēs ar pievienotiem kadmija, vara, mangāna, svina un cinka sāļiem divās dažādās koncentrācijās. Vizuāli novēroj…
Expression Patterns and Subcellular Localization of Carbonic Anhydrases Are Developmentally Regulated during Tooth Formation
2014
Abstract Carbonic anhydrases (CAs) play fundamental roles in several physiological events, and emerging evidence points at their involvement in an array of disorders, including cancer. The expression of CAs in the different cells of teeth is unknown, let alone their expression patterns during odontogenesis. As a first step towards understanding the role of CAs during odontogenesis, we used immunohistochemistry, histochemistry and in situ hybridization to reveal hitherto unknown dynamic distribution patterns of eight CAs in mice. The most salient findings include expression of CAII/Car2 not only in maturation-stage ameloblasts (MA) but also in the papillary layer, dental papilla mesenchyme, …
A Robust Generic Method for Grid Detection in White Light Microscopy Malassez Blade Images in the Context of Cell Counting
2015
AbstractIn biology, cell counting is a primary measurement and it is usually performed manually using hemocytometers such as Malassez blades. This work is tedious and can be automated using image processing. An algorithm based on Fourier transform filtering and the Hough transform was developed for Malassez blade grid extraction. This facilitates cell segmentation and counting within the grid. For the present work, a set of 137 images with high variability was processed. Grids were accurately detected in 98% of these images.
Immunohistochemical Evaluation of Periodontal Regeneration Using a Porous Collagen Scaffold.
2021
(1) Aim: To immunohistochemically evaluate the effect of a volume-stable collagen scaffold (VCMX) on periodontal regeneration. (2) Methods: In eight beagle dogs, acute two-wall intrabony defects were treated with open flap debridement either with VCMX (test) or without (control). After 12 weeks, eight defects out of four animals were processed for paraffin histology and immunohistochemistry. (3) Results: All defects (four test + four control) revealed periodontal regeneration with cementum and bone formation. VCMX remnants were integrated in bone, periodontal ligament (PDL), and cementum. No differences in immunohistochemical labeling patterns were observed between test and control sites. N…
La serpiente que se ha introducido en la familia. La representación de la mujer maligna en Carmen Laforet.
2021
La representación del mal, encarnado en algunos personajes, constituye una constante de la narrativa de Carmen Laforet. A partir de Gloria (Nada), que “se ha introducido en esta casa como una serpiente”, pasando por Paulina (La mujer nueva) que representaría la causa principal de la caída social de la familia Nives, hasta llegar a Anita Corsi (La insolación) sobre la que caen prejuicios por su conducta contraria a las convenciones sociales, se observa que estas mujeres delimitan el marco dicotómico entre norma, complaciente y proclive al dictamen franquista y católico, y subversión. El trabajo, por tanto, tiene como objetivo fijar algunos elementos connotativos de este tipo de representació…
Détection de formes compactes en imagerie : développement de méthodes cumulatives basées sur l'étude des gradients : Applications à l'agroalimentaire
2018
The counting cells (Malassez, Thoma ...) are designed to allow the enumeration of cells under a microscope and the determination of their concentration thanks to the calibrated volume of the grid appearing in the microscopic image. Manual counting has major disadvantages: subjectivity, non-repeatability ... There are commercial automatic counting solutions, the disadvantage of which is that a well-controlled environment is required which can’t be obtained in certain studies ( eg glycerol greatly affects the quality of the images ). The objective of the project is therefore twofold: an automated cell count and sufficiently robust to be feasible regardless of the acquisition conditions.In a f…
