OBJECTIVES/HYPOTHESIS An outpatient surgical procedure for snoring and obstructive sleep apnea syndrome (OSAS) should not only stiffen the soft palate, but also widen the opening of retropalatal space. This study presents a concurrent palatal implants (PI) and uvulopalatal flap (UPF) in the outpatient setting under local anesthesia for OSAS patients. STUDY DESIGN Prospective study. METHODS ...

In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.

The poly(A)-binding protein (PABP), in a complex with the 3'poly(A) tail of eukaryotic mRNAs, plays important roles in the control of translation and message stability. All known examples of PABP mRNAs contain an extensive A-rich sequence in their 5' untranslated regions. Studies in mammalian cells undergoing growth stimulation or terminal differentiation indicate that PABP expression is regula...

Phosphoinositides play an important role in cell signaling and cytoskeleton function. In this study, we investigate the effect of brain aging on phosphatidylinositol-4monophosphate (PI(4)P) and phosphatidylinositol-4,5-bisphosphate (PI(4,5)P ) synthesis by PI 4-kinase (PI4K) and PI(4)P 5-kinase (PIP5K) in cortical synaptic plasma membranes in the presence of endogenous and exogenous substrates ...

Rats with or without 0.5% tolbutamide in the diet were iniected over a 5-day period with growth hormone, ACTH, cortisol, dexamethasone, or various mixtures of these diabetogenic hormones and the daily alterations in blood glucose (BG), serum (Sl), and pancreatic insulin (PI) concentrations followed as well as glucosuria. GH (5 mg/day) increased the insulin concentration in the pancreas and seru...

The purpose of this study was to determine whether phosphatidylinositol 3-kinase (PI 3-K) inhibitors could modulate the apoptotic activity of the anticancer drugs cisplatin, 5-fluorouracil or docetaxel in an oral squamous cell carcinoma (OSCC) cell line, HSC-2. In preliminary experiments, cisplatin, 5-fluorouracil and docetaxel inhibited the proliferation of OSCC cells in a dose-dependent manne...

The viability of Giardia muris cysts was studied with the fluorogenic dyes fluorescein diacetate (FDA) and propidium iodide (PI). G. muris cysts were seen to fluoresce intensely green with FDA at an excitation wavelength of 450 to 490 nm. Cysts stained with PI fluoresced bright orange at an excitation wavelength of 450 to 490 nm and bright red at 545 to 546 nm. Examination of isolated G. muris ...

A module is said to be $PI$-extending provided that every projection invariant submodule is essential in a direct summand of the module. In this paper, we focus on direct summands and indecomposable decompositions of $PI$-extending modules. To this end, we provide several counter examples including the tangent bundles of complex spheres of dimensions bigger than or equal to 5 and certain hyper ...
