BACKGROUND & AIMS Two ready-to-use parenteral nutritions (PN) have been developed, for the first days of life of the premature newborn, along with syringes of lipid emulsion with or without vitamins. Long-term physico-chemical stability for storage in wards was assessed. METHODS Physico-chemical stability of PN: visual inspection, particle size, pH, osmolarity measurement, amino acids, glucos...

During both development and regeneration, the survival of neurones and the growth of axons are controlled by inherent neuronal properties, conditions in the axonal environment, and the establishment of appropriately timed and specific functional contacts. To study the effects of extrinsic influences on the survival, growth and connectivity of axotomized neurones in the mature mammalian CNS, we ...

Net photosynthesis (Pn) of loblolly pine (Pinus taeda L.) foliage was monitored monthly in 14 yr old stands under near-ambient conditions over an entire year in upper and lower crowns and in both nonfertilized stands and stands receiving nutrient amendments for six consecutive years. Air temperature, humidity, vapor pressure deficit (VPD), photosynthetic photon flux density (PPFD), and plant wa...

We solve an open problem of Diaconis that asks what are the largest orders of pn and qn such that Zn, the pn× qn upper left block of a random matrix Γn which is uniformly distributed on the orthogonal group O(n), can be approximated by independent standard normals? This problem is solved by two different approximation methods. First, we show that the variation distance between the joint distrib...

Although parenteral nutrition (PN) is an important treatment for patients who are unable to tolerate enteral nutrition (EN), recent international guidelines recommended that PN should be reserved and initiated only after 7 days in well-nourished patients. This retrospective study was conducted to analyze the effect on clinical outcomes of a PN protocol with PN starting 4 days after admission to...

Axonal regeneration of retinal ganglion cells (RGCs) into a normal or pre-degenerated peripheral nerve graft after an optic nerve pre-lesion was investigated. A pre-lesion performed 1-2 weeks before a second lesion has been shown to enhance axonal regeneration in peripheral nerves (PN) but not in optic nerves (ON) in mammals. The lack of such a beneficial pre-lesion effect may be due to the lon...

Hop (Humulus lupulus L.), as a key ingredient for beer brewing, is also a source of many biologically active molecules. A notable compound, 8-prenylnaringenin (8-PN), structurally belonging to the group of prenylated flavonoids, was shown to be a potent phytoestrogen, and thus, became the topic of active research. Here, we overview the pharmacological properties of 8-PN and its therapeutic oppo...

Myosin-V is a processive two-headed actin-based motor protein involved in many intracellular transport processes. A key question for understanding myosin-V function and the communication between its two heads is its behavior under load. Since in vivo myosin-V colocalizes with other much stronger motors like kinesins, its behavior under superstall forces is especially relevant. We used optical t...

clericuzio-type poikiloderma with neutropenia (pn) is characterized by poikiloderma, non-cyclic  neutropenia,  recurrent  sinopulmonary  infections,  pachyonychia,  and  palmo- plantar hyperkeratosis. mutations in the c16orf57 gene, which is located on chromosome 16q13, have been identified as the cause of pn. pn was first described by clericuzio in navajo indians. herein, we reported the clini...
