The alimentary system of Habrotrocha rosa is composed of the alimentary channel, five digestive glands and another gland which is in close relation to the intestinal syncytium. After the present investigation, the alimentary channel can be divided into sections which clearly differ from each other,
Numerous crystalline inclusions are found in the nutritive cells lining the larval cavities of the galls induced by Diplolepis rosae L. on Rosa canina L. Electron microscopic investigations show that these intracytoplasmic inclusions consist of staggered, closely parallel, and slightly wavy
BACKGROUND
Abdominal adhesions are pathological connections in peritoneal surfaces that are created after abdominal surgery. The aim of this study was to evaluate the inhibitory effect of Rosa damascena extract on adhesions, considering the antioxidant properties of rose.
METHODS
Thirty healthy rats
OBJECTIVE
To assess and compare the antimicrobial potential and determine the minimum inhibitory concentration (MIC) of Jasminum grandiflorum and Hibiscus rosa-sinensis extracts as potential anti-pathogenic agents in dental caries.
METHODS
Aqueous and ethanol (cold and hot) extracts prepared from
Floral foraging resources are valuable for pollinator conservation on farmland, and their provision is encouraged by agri-environment schemes in many countries. Across Europe, wildflower seed mixtures are widely sown on farmland to encourage pollinators, but the extent to which key pollinator groups
A case is reported of iatrogenic mitral valve chordal rupture occurring during transcatheter aortic valve implantation (TAVI) with an inflatable and repositionable valve (Direct Flow; Direct Flow Medical, Santa Rosa, CA, USA). The specific implantation technique requires initial valve advancement
We have used a retroviral gene trap in embryonic stem (ES) cells to derive a recessive embryonic lethal mouse strain, ROSA beta-geo5. Mutant embryos display an enlarged pericardial cavity, bradycardia, a dilated fourth ventricle in the brain, and die between embryonic days 11 and 12. Whereas heart
Cloacal and nasal bacterial flora of Lepidochelys olivacea (Testudines: Cheloniidae) from the North Pacific coast of Costa Rica. The aerobic cloacal and nasal bacterial flora of 45 apparently healthy female olive ridley sea turtles (Lepidochelys olivacea) was studied at Nancite nesting beach, in
BACKGROUND
Vaginal cavity represents a good site for drug administration and delivery.
OBJECTIVE
The aim of this work was the design of new mucoadhesive semisolid dosage forms for vaginal delivery of benzydamine.
METHODS
Simple gels, obtained by using sodium carboxymethylcellulose (NaCMC) and
Neural precursor cells (NPCs) are promising grafts for treatment of traumatic CNS injury and neurodegenerative disorders because of their potential to differentiate into neurons and glial cells. When designing clinical protocols for NPC transplantation, it is important to develop alternatives to
To explain the evolutionary origin of vertebrate teeth from odontodes, it has been proposed that competent epithelium spread into the oropharyngeal cavity via the mouth and other possible channels such as the gill slits [Huysseune et al., 2009, J. Anat. 214, 465-476]. Whether tooth formation
BACKGROUND
Oral diseases are among the major public health problems and the commonest of chronic diseases that affect mankind. The application of natural products for the control of oral diseases is considered as an interesting alternative to synthetic antimicrobials due to their lower negative
OBJECTIVE
The purpose of this study was to determine whether natural dyes facilitate posterior hyaloid detachment (posterior vitreous detachment [PVD]) and retinal internal limiting membrane (ILM) peeling in human eyes.
METHODS
Open-sky vitrectomy with posterior hyaloid and ILM removal was performed
The development of the Cre recombinase-controlled (Cre/LoxP) technique allows the manipulation of specific tumorigenic genes, temporarily and spatially. Our original intention of this study was to investigate the role of Kras and p53 in the development of urinary bladder cancer. First, to validate
The origin, roles and fate of progenitor cells forming synovial joints during limb skeletogenesis remain largely unclear. Here we produced prenatal and postnatal genetic cell fate-maps by mating ROSA-LacZ-reporter mice with mice expressing Cre-recombinase at prospective joint sites under the control
