Effect of growth regulators onin vitro propagation ofFicus benjamina cv. Exotica

1994

Stem internodes with axillary buds were excised from 5-year old trees ofFicus benjamina cv. Exotica. The effect of 6-benzylaminopurine (BAP), gibberellic acid (GA3), indole-3-acetic acid (IAA), naphthaleneacetic acid (NAA), and 2,4-dichlorophenoxyacetic acid (2,4-D) on shoot growth and proliferationin vitro was investigated. Multiple shoots were developed after 3–4 weeks from stem internodes with axillary buds incubated in Murashige and Skoog (MS) medium supplemented with phloroglucinol (PG) and BAP. Optimum shoot proliferation took place in the presence of 1.0 mg l−1 BAP. Shoots obtained could be elongated in a medium with 0.5 mg l−1 GA3 prior to their rooting. The root initiation was succ…

In vitro propagation ofSalix tarraconensis Pau ex Font Quer, an endemic and threatened plant

1996

Salix tarraconensis Pau ex Font Quer, an endemic willow species from northeast Spain, was micropropagated with nodal segments. Shoot multiplication was obtained with different cytokinins, either on Murashige and Skoog medium or woody plant medium. Best results for shoot formation were obtained on Murashige and Skoog medium containing 4.9 μM of 6-γ-γ-dimethylallylaminopurine. Shoots showed strong apical dominance, and some cultures displayed apical necrosis. Benzyladenine gave the worst results; shoots displayed very slow growth, deformed leaves, and hyperhydrity. Good rooting of shoots was obtained with different auxins or without plant growth regulators on woody plant medium. The best resu…

Factors influencing axillary shoot proliferation and adventitious budding in cedar.

2005

We developed procedures for in vitro cloning of Cedrus atlantica Manetti and C. libani A. Rich explants from juvenile and mature plants. Explant size was one determinant of the frequency of axillary bud break in both species. Shoot tips and nodal explants mainly developed calli, whereas bud sprouting occurred in defoliated microcuttings cultured on a modified Murashige and Skoog medium without growth regulators. Isolation and continuous subculture of sprouted buds on the same medium allowed cloning of microcuttings from C. atlantica and C. libani seedlings and bicentennial C. libani trees, thus providing a desirable alternative for multiplying mature trees that have demonstrated superior ch…

Diagnóstico diferencial inmunomorfológico de las lesiones quísticas maxilares con queratinización

2011

ResumenObjetivosLos quistes maxilares con queratinización son formas lesionales de carácter controvertido y de relevancia clínica, dada la implicación clínico-evolutiva del llamado tumor odontogénico queratoquístico (TOQ). En el presente estudio nos planteamos valorar la utilidad de las técnicas inmunohistoquímicas en la identificación de estas lesiones.Material y métodosSe analizan de forma retrospectiva las lesiones quísticas maxilares dotadas de fenómenos de queratinización interna, diagnosticadas en un mismo centro hospitalario, a lo largo de un periodo de 4 años, realizando un estudio inmunohistoquímico mediante la aplicación de un panel de cinco anticuerpos (Ki67, Bcl-2, p53, CK19, D2…

Micropropagation of bay laurel (Daphne gnidiumL.)

1996

SummaryProcedures have been developed for the micropropagation of Daphne gnidium, a shrub species of ecological interest, using explants of juvenile and adult origin. Shoot proliferation rates were significantly affected by both salt formulation and benzylade- nine concentration. Best results were obtained on WP medium with 5 µM BA. The presence of indoleacetic acid in the induction medium improved BA-induced axillary bud proliferation from juvenile explants. Rooting of shoots produced in culture was difficult, especially those of adult origin. Besides an absolute requirement for auxin, calcium concentration and the pH of the medium affected the formation of adventitious roots from regenera…

Surgical treatment of early breast cancer in day surgery.

2007

Quadrantectomy and associated sentinel lymph node biopsy (SLNB) is currently employed in most breast surgery centres as the gold standard in the treatment of early breast cancer. This approach has a modest morbidity and can usually be performed in a day-surgery regimen, leading to best acceptance by the patients. This reports outlines the experience of our Breast Unit with quadrantectomy and SLNB in day surgery for early breast cancer. One hundred patients presenting to our institution with primary invasive breast cancer measuring less than 3 cm and clinically negative axillary nodes underwent quadrantectomy and SLNB in day surgery. For 60 women with breast cancer the sentinel node was nega…

Immediate or delayed retrieval of the displaced third molar: A review

2019

Background The displacement of a third molar is a rare occurrence, but it could lead to serious and/or life threatening complication. Aim of this review is to understand the most correlated causes of displacement and the possible solutions proposed in literature to avoid and solve this complication for maxillary and mandibular third molars at the appropriate time. Material and methods A search for "third molar displacement" was performed by using Pubmed database. Articles referred to soft tissues displacement, from 1957 to 2018, were included in the review. The references lists of all eligible articles were examined and additional studies were added to the review only if indexed on Pubmed. …

Pattern of distribution and etiologies of Midline diastema among Kurdistan-region Population

2020

Background Aim of study was to evaluate the prevalence and etiological factors that contribute in midline diastema in Kurdistan region-Iraq population among different age groups and genders. Material and Methods Orthodontic patients sample of (EX: 1021orthodontic patients (537 males and 484 females) were randomly selected from Kurdistan-region population, attending to orthodontic department of khanzad polyclinic teaching center (General directorate of hawler / Ministry of health/ Kurdistan region- Iraq) during 2018-2019 period. Aged (13-35 years) with mean age ± SD was 19.6 ± 4.8 years, with a median of 19 years. The examination included patient history taking, intraoral examination, photog…

Accessory submaxillary gland : two new case reports and a literature review

2020

Background The accessory submaxillary gland is a very uncommon anatomical variant, and incidence in the general population has not yet been quantified. The presence of pathology in these glands is rarer still, thus often going unnoticed. Material and methods We describe two accessory submaxillary gland cases, one asymptomatic and the other with chronic sialadenitis in the main and accessory gland caused by sialolithiasis. Although our diagnosis was by computerized tomography, magnetic resonance sialography is helpful to understand and describe this entity with greater precision. Results The first case report is an incidental finding and no intervention was required. However, case report num…
