PURPOSE To determine the profile of neurodegeneration in Leber hereditary optic neuropathy (LHON). METHODS We quantitated serum levels of phosphorylated neurofilament heavy chain (pNF-H) in a Brazilian pedigree of 16 affected patients and 59 carriers with LHON, both molecularly characterized as harboring the G to A mutation at nucleotide 11,778 of the mitochondrial genome. The association of ...

Plexiform neurofibroma (PNF) of the scalp is an extremely rare lesion reported in association with neurofibromatosis (NF). Occipital location of PNF is even more infrequent; we reported one pediatric case of PNF in occipito-cervical region with multiple small occipital bone defects and associated with NF-1.

BACKGROUND Percutaneous needle fasciotomy (PNF) is a minimally invasive technique used to manage Dupuytren's contracture. We compared outcomes of PNF versus open fasciectomy (OF) to examine the suitability of PNF in Australia. METHOD A retrospective cohort study using two questionnaires regarding Dupuytren's treatment was used to assess patients with uncomplicated primary disease. The primary...

Purpose: Manual lymphatic drainage (MLD) and proprioceptive neuromuscular facilitation (PNF) are potential therapeutic strategies to reduce mastectomy-induced edema. The purpose of this study was to investigate whether the combination of these therapies would induce synergistic effects to treat lymphedema-related complications and to analyze a possible physiological mechanism involved in the ob...

The effects of proprioceptive neuromuscular facilitation (PNF) stretch techniques on older adults are unknown and the physiological changes associated with aging may lead to differential responses to PNF stretching. Therefore, the purpose of this experiment was to examine the effects of PNF stretch techniques and EMG activity in older adults. Three PNF stretch techniques: static stretch (SS), c...

Growth of the aerial part of the plant is dependent upon the maintenance of the shoot apical meristem (SAM). A balance between the self-renewing stem cells in the central zone (CZ) and organogenesis in the peripheral zone (PZ) is essential for the integrity, function, and maintenance of the SAM. Understanding how the SAM maintains a balance between stem cell perpetuation and organogenesis is a ...

BACKGROUND Norms clarification has been identified as an effective component of college student drinking interventions, prompting research on norms clarification as a single-component intervention known as Personalized Normative Feedback (PNF). Previous reviews have examined PNF in combination with other components but not as a stand-alone intervention. OBJECTIVES To investigate the degree to...

Islet primary nonfunction (PNF) is defined as the loss of islet function after transplantation for reasons other than graft rejection. It is a major obstacle to successful and efficient islet transplantation. DcR3/TR6 is a soluble death decoy receptor belonging to the tumor necrosis factor (TNF) receptor family, and it can block apoptosis mediated by several TNF receptor family members such as ...

BACKGROUND Elastic resistance bands (ERB) combined with proprioceptive neuromuscular facilitation (PNF) are often used in resistance muscle training programs, which have potential effects on peripheral muscle strength. However, the effects of the combination of ERB and PNF on respiratory muscle strength warrant further investigation. OBJECTIVES The assessment of the effects of PNF combined wi...
