The papillary layer of the oral part of the human soft palate was studied in 31 subjects of different age by means of histological, immunohistochemical and scanning electron microscopical methods. For scanning electron microscopy a new maceration method was introduced. Results determine epithelial thickness, height and density of connective tissue papillae and their 3-dimensional architecture i...

objective: the aim of this study was to compare subepithelial connective tissue grafts (sctg) and coronally advanced flaps (caf) with the addition of emdogain in the treatment of gingival recession. materials and methods : this interventional randomized controlled clinical trial involved eleven patients and 31 teeth demonstrating facial recessions of > 2 mm identified as miller's class i or ii....

the study aimed to investigate the microsporogenesis, tapetum and pollen development in petunia hybrida juss.under control and air pollution condition. the connective shows a well-developed placentoid, giving thesporogenous tissue a crescent-shape. the sporogenous tissue of each of the four anther locules is surrounded bydimorphic tapetum. the outer (towards the epidermis) and inner (towards th...

background: the differences between marginal gingiva and interdental papilla may be due to variation in the molecular composition of these two different anatomical structures. the aim of this study was to evaluate the staining intensity of fibronectin in human marginal gingiva and interdental papilla. materials and methods: in a prospective analytical study, 16 healthy subjects needing crown le...

It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...

Myocarditis is a serious manifestation of systemic lupus erythematosus. It is reported that 5-10% of the patients present symptomatic myocarditis. However, myocarditis in mixed connective tissue disease is uncommon. Only a few cases with mixed connective tissue disease patients who presented symptomatic myocarditis were reported. We herein describe a patient with mixed connective tissue disease...

The modified extended Hansen method was tested for the first time to determine partial solubility parameters of non-polymeric pharmaceutical excipients. The method was formerly tested with drug molecules, and is based upon a regression analysis of the logarithm of the mole fraction solubility of the solute against the partial solubility parameters of a series of solvents of different chemical c...

The main contribution of this paper is to introduce an autonomous definition of the connective “fuzzy exclusive or” (fuzzy Xor, for short), which is independent from others connectives. Also, two canonical definitions of the connective Xor are obtained from the composition of fuzzy connectives, and based on the commutative and associative properties related to the notions of triangular norms, t...

The purpose of this study is to investigate the effect of chest wall configuration at end expiration on tidal volume (VT) response during CO2 rebreathing. In a group of 11 healthy male subjects, the changes in end-expiratory and end-inspiratory volume of the rib cage (delta Vrc,E and delta Vrc,I, respectively) and abdomen (delta Vab,E and delta Vab,I, respectively) measured by linearized magnet...
