Abstract:

The aim of the study was to investigate the structure and topography of endogenous secretory tissues of <i>Inula helenium</i> L. By using light and electron microscopy, morphological and anatomical observations of stems, leaves and rhizomes were made. It was shown that in the stems secretory cavities were situated in the vicinity of phloem and xylem bundles. The number of the reservoirs reached its maximum value (34) at shoot flowerig termination, whereas the cavities with the largest diameter were observed at full flowering stage (44.6 µm). In the leaf petioles and midribs, the re

Abstract:

Silphium perfoliatum L. (Asteraceae) is a North American perennial used as a medicinal, fodder, honey-bearing, and ornamental plant as well as for remediation of degraded soils. The location and structure of secretory reservoirs in the stem were examined with the use of light microscopy in cup plant stems. The stems were analysed at various heights (0-2 cm above the root collar, ½ of the stem length, and 0-2 cm below the stem apex/inflorescence) and in three vegetation phases (vegetative phase, full bloom, withering). The plants belonged to the collection of the Department of Vegetable Crops a

Abstract:

Secretory structures in terrestrial plants serve as reservoirs for a variety of secondary metabolites. Among these, the secretory cavity of the Rutaceae family is notable for containing essential oils with a wide range of applications. However, the molecular basis underlying secretory cavity development is unknown. Here, we reveal a molecular framework for Citrus oil gland formation. Using genetic mapping and genome editing, we demonstrated that this process requires LATE MERISTEM IDENTITY1 (LMI1), a key regulator of leaf serration. A conserved GCC box element of the LMI1 promoter recruits DOR

Abstract Triatoma lecticularia (Hemiptera: Reduviidae) (Stal, 1859) is a potential vector of Chagas’s disease and the comprehension of its reproductive biology is an important tool to control this insect.

Whithin insects the spermatheca shows a wide morphological diversity and the analysis of this characteristic can contribute to understand the reproductive biology of the species.

Abstract:

One impediment for a wider application of islet transplantation is the limited number of donor pancreata for islet isolation. A more efficient utilization of available organs could in part alleviate this problem. Perfluorocarbons (PFCs) have a high oxygen solubility coefficient and maintain high oxygen partial pressures for extended time. They serve also as oxygen “reservoirs” for harvested organs in pancreas organ transplantation. The aim of this study was to test whether the use of PFCs could also be beneficial for the secretory activity and overall viability of cultured purified islets befo

However, there has been less focus on the protein components of the secretory machinery itself.

Abstract:

Tuberculosis still remains one of the most fatal infectious diseases. Streptomycin (SM) is the drug of choice, especially for patients with multidrug-resistant tuberculosis or category II patients, because it targets the protein synthesis machinery by interacting with steps of translation. Several mechanisms have been proposed to explain the resistance, but our knowledge is inadequate. Secretome often plays an important role in pathogenesis and is considered an attractive reservoir for the development of novel diagnostic markers and targets. In this study, we analyze the secretory proteins of

Abstract:

The high human cost of Zika virus infections and the rapid establishment of virus circulation in novel areas, including the United States, present an urgent need for countermeasures against this emerging threat. The development of an effective vaccine against Zika virus may be problematic because of the cross reactivity of the antibodies with other flaviviruses leading to antibody-dependent enhancement of infection. Moreover, rapidly replicating positive strand RNA viruses, including Zika virus, generate large spectrum of mutant genomes (quasi species) every replication round, allowing rapid s

Abstract:

The morphology and fine structure of the two major sting glands in the primitive Australian bull ant, Myrmecra gulosa, are described. The cells of the glandular epithelium of the tubiform Dufour's gland are characterised by a well developed vesicular smooth endoplasmic reticulum, numerous lamellar inclusions, and microvillar differentiations of the apical cell membrane. The cells of the secretory filaments of the venom gland contain a very extensive granular endoplasmic reticulum and numerous Golgi vesicles. The highly proteinaceous secretion reaches the filament lumen through the intracellula

Examination of the testes revealed that they were paired, elongated and not fringed organs. Histologically, the testes presented three distinct regions: cranial espermatogenic; transistion espermatogenic and secretory; and caudal exclusive

European badgers are a wildlife reservoir of bovine tuberculosis in parts of Great Britain. Accurate diagnosis of tuberculosis in badgers is important for the development of strategies for the control of the disease. Sensitive serological tests for badger TB are needed for reasons such as cost and simplicity. Assay of mucosal IgA could be useful for diagnosing respiratory pathogens such as Mycobacterium bovis and for monitoring the response to mucosal vaccination. To develop an IgA assay, we purified secretory IgA from badger bile, identifying secretory component (SC), heavy chain (HC) and lig

Mesenchymal stem/stromal cells (MSCs) are a reservoir for tissue homeostasis and repair that age during organismal aging. Beside the fundamental in vivo role of MSCs, they have also emerged in the last years as extremely promising therapeutic agents for a wide variety of clinical conditions. MSC use frequently requires in vitro expansion, thus exposing cells to replicative senescence. Aging of MSCs (both in vivo and in vitro) can affect not only their replicative potential, but also their properties, like immunomodulation and secretory profile, thus possibly compromising their therapeutic effe

Патология глоточной миндалины способствует развитию хронического синусита у детей посредством нескольких различных механизмов, в том числе как резервуар бактерий, как причина назальной обструкции на уровне задних отделов носа и носоглотки и нарушения мукоцилиарного клиренса.
