Sunto. – In questo lavoro si generalizzano alcuni risultati di [3] riguardanti la proprieta’ di alcune curve nodali, su superficie non-singolari in Pr, di essere ”geometricamente linearmente normali” (concetto che estende la ben nota proprieta’ di essere linearmente normale). Precisamente, per una data curva C, irriducibile e dotata di soli punti nodali come uniche singolarita’, che giace su un...
BACKGROUND A large amount of organophosphate pesticides (OPs) are used in agriculture in China every year, contributing to exposure of OPs through dietary consumption among the general population. However, the level of exposure to OPs in China is still uncertain. OBJECTIVE To investigate the effect of the exposure to OPs on the neonatal neurodevelopment during pregnancy in Shenyang, China. ...
Induced pluripotent stem (iPS) cells are at the forefront of research in regenerative medicine and are envisaged as a source for personalized tissue repair and cell replacement therapy. Here, we demonstrate for the first time that oligodendrocyte progenitors (OPs) can be derived from iPS cells generated using either an episomal, non-integrating plasmid approach or standard integrating retroviru...
BACKGROUND AND PURPOSE Although symptomatic carotid stenosis is associated with 3-fold increased risk of early stroke recurrence, the pathophysiologic mechanisms of high early stroke risk have not been established. We aimed to investigate the relationship between early stroke recurrence after initial symptoms and histological features of plaque inflammation and instability in resected carotid p...
Background: One of the main goals of health systems is to protect people against financial risks associated with diseases that can be catastrophic for patients. In 2014, Health Sector Evolution Plan (HSEP) was implemented in Iran; one of the objectives of HSEP was to reduce out-of-pocket payments and provide more financial protection for people. Therefore, the present study a...
Background: During the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. Lactococcus lactis (L. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. Hence, L. lactis is an ideal candidate for mucosal immunotherapy. Profilin (Che a 2), the major allergen in Chenopodium album, is one ...
We describe an implementation of the Cooley Tukey complex-to-complex FFT on the Connection Machine. The implementation is designed to make e ective use of the communications bandwidth of the architecture, its memory bandwidth, and storage with precomputed twiddle factors. The peak data motion rate that is achieved for the interprocessor communication stages is in excess of 7 Gbytes/s for a Conn...
Proliferative oligodendrocyte progenitor cells (OPs) express large, delayed outward-rectifying K(+) currents (I(K)), whereas nondividing immature and mature oligodendrocytes display much smaller I(K). Here, we show that up-regulation of I(K) occurs in G(1) phase of the cell cycle in purified cultured OPs and is the result of an RNA synthesis-dependent, selective increase of the K(+) channel sub...
Objectives. The aim of this study was to establish the reliability of the "chewing" subscale of the OPS-NVI, a novel tool designed to estimate presence and severity of orofacial pain in nonverbal patients. Methods. The OPS-NVI consists of 16 items for observed behavior, classified into four categories and a subjective estimate of pain. Two observers used the OPS-NVI for 237 video clips of peopl...
Vitrification of oocytes has been applied recently for humans, but remains elusive. The microtubules of oocytes are vulnerable to cryoprotectants and thermal changes. Using mouse oocytes, the effects of vitrification in open pulled straws (OPS) were investigated on survival, the meiotic spindle, and chromosomes and compared with conventional straws. Mature oocytes were allocated to four groups ...
