Pruacan is a rare medicinal plant endemic to the Dieng Plateau of Central Java, Indonesia which has properties as an aphrodisiac. Increasing genetic variability ofthis in order support breeding programs and increase productivity active ingredients this important. This study aimed evaluate effect chemical mutagen EMS on growth development vitro culture pruacan lethal dose determination. Embryoge...

When small explants from early gastrulae of Xenopus laevis are allowed to develop in a buffered salt solution there is a considerable difference between the patterns of differentiation obtained from different dorsoventral levels of the marginal zone. These patterns of differentiation correspond to the fates of the different regions in the course of normal development. They are not altered if se...

Despite intensive research efforts over the past years, regeneration of injured axons in the central nervous system remains elusive. In the quest for neurostimulatory agents that promote regeneration, well-defined models and analysis methods are required. Tissue explant cultures closely resemble the in vivo situation, making them ideal to study the effect of compounds on the neuro-glial network...

The transcellular signaling of neurotrophins is postulated, but evidence is scarce. We now show that a small number of NT4- and BDNF-overexpressing neurons in the cortical explant of thalamocortical cocultures rapidly evoked a Trk receptor-dependent upregulation of neuropeptide Y (NPY) mRNA in interneurons. In contrast to BDNF, the action of NT4 was independent of calcium influx through NMDA re...

Aims-To investigate the level of matrix metalloproteinase activity during the time-course of cartilage explant proteoglycan breakdown; to determine the effects of selective small-molecule inhibitors of matrix metalloproteinases on proteoglycan degradation.Methods-The levels of matrix metalloproteinase activity in cartilage explant cultures and conditioned media were monitored by use of a quench...

Porcine tracheal rings and lung explants alone and in combination with monolayer cultures of porcine lung fibroblasts (PLF) were separately inoculated with virulent strains of Mycoplasma hyopneumoniae and incubated at various times. The preparations were observed by bright-field, phase-contrast, and scanning electron microscopy. In PLF cultures, the strains at initial concentrations of 10(1.3) ...

Neural retina can be isolated from mouse embryos and maintained in culture for 2-3 weeks. In such retinal explant cultures, precursor cells differentiate into neurons and glial cells and form three cellular layers, mimicking well the normal development. This explant culture system is suitable for genetic manipulation, such as retrovirus-mediated gene transfer. Retroviral vectors can efficiently...

ABSTRACT Gerbera (Gerbera jamesonii Bolus ex Hook. F.; Asteraceae), is one of the most economically important ornamental plants due to its aesthetic value. In present study, we established a micropropagation method for large-scale production quality planting material gerbera ‘Pink Melody’. Eighty-six percent capitulum explants produced adventitious shoots (15.44 ± 0.34 per capitulum) on Murashi...

Abstract Introduction The Penuma penile implant (PPI) is a subcutaneous silicone intended to increase length and girth. Only one case report series of four patients have been published on the complications PPIs. Objective To single center experience treating PPI both prior after removal. Methods Patients with history surgery treated at our were identified between 2012 2022. Demographic data, da...

Conservation and propagation of species using biotechnologic tools-such as plant tissue culture-are relevant when natural propagation is hampered for various reasons. In vitro techniques allow mass multiplication and propagation under pathogen-free conditions but also override dependence on season for availability of plant material. Moreover, in vitro genetic manipulation of a species, invariab...
