Martin F Heyworth
Enterocytozoon bieneusi and Encephalitozoon intestinalis are microsporidia that infect the human gastrointestinal (GI) tract. Each of these microsporidia has been shown to infect various non-human hosts (mammalian and avian), raising the possibility of inter-species transmission, for example, from such hosts to human subjects via waterborne dispersal of microsporidian spores. During the past two decades, genome sequencing has delineated more than 90 genotypes of Ent. bieneusi, and has led to the conclusion that not all the genotypes of this organism infect human subjects...

Human amniotic membrane (HAM) is derived from the fetal membranes which consist of the inner amniotic membrane made of single layer of amnion cells fixed to collagen-rich mesenchyme attached to chorion. HAM has low immunogenicity, anti-inflammatory properties and their cells can be isolated without the sacrifice of human embryos. Amniotic membrane has biological properties which are important for the experimental and clinical applications in managing patients of various medical specialties. Abundant, natural and wonderful biomembrane not only protects the foetus but also has various clinical applications in the field of dermatology, ophthalmology, ENT surgery, orthopedics and dental surgery...

OBJECTIVES: Fibrous dysplasia of bone is a rare sporadic benign congenital condition in which normal cancellous bone is replaced by fibro-osseous tissue with immature osteogenesis. Sarcomatous transformation is exceptional. Lesions may involve one bone (monostotic) or several (polyostotic). Fibrous dysplasia may be associated with café-au-lait skin macules and endocrinopathy in McCune-Albright syndrome, or with myxoma in Mazabraud's syndrome. METHODS: We report ten cases of patients followed up for craniofacial fibrous dysplasia in our center between 2010 and 2015...

We describe the design, synthesis, and opioid activity of fluoroalkene (Tyr1-ψ[(Z)CF=CH]-Gly2) and trifluoroethylamine (Tyr1-ψ[(S)/(R)-CF3CH-NH]-Gly2) analogs of the endogenous opioid neuropeptide, Leu-enkephalin. The fluoroalkene peptidomimetic exihibited low nanomolar functional activity (5.0 ± 2 nM and 60 ± 15 nM for δ- and μ-opioid receptors, respectively) with a μ/δ-selectivity ratio that mimicked the natural peptide. However, the trifluoroethyl-amine peptidomimetics, irrespective of stereochemistry, did not activate the opioid receptors, which suggest that bulky CF3 substitu-ents are not tolerated at this position...

The goal of this work was the identification and quantification of phytoprostanes (PhytoPs) in three types of nuts: "Walnut", "Macadamia", and "Pecan". This study represents a first approach to the relationship between the quantitative and qualitative PhytoP profiles in the "Macadamia" and "Pecan" nuts subjected to fried salt or fried honey processing. The kernels were found to contain 9-F1t-PhytoP, 9-epi-9-F1t-PhytoP, 16-B1-PhytoP, ent-16-B1-PhytoP, 9-L1-PhytoP, and ent-9-L1-PhytoP. "Macadamia" fried salt nuts were the only ones that produced 9-epi-9-D1-PhytoP and 9-D1-PhytoP...

BACKGROUND: Cystic fibrosis (CF) patients are advised to derive 35% of their daily energy intake from dietary fat. Whether this high fat intake is associated with dyslipidaemia is unknown. We described the lipid profile and dietary intake in paediatric patients with CF. METHODS: 110 fasting lipid concentrations of 110 Dutch patients with CF were studied, along with 86 measurements of dietary intake. For the total group and for boys and girls separately, the lipid profile and the dietary intake were investigated...

Surgical results in obstructive sleep apnea syndrome (OSAS) vary greatly, whatever the surgical technique or site treated. Most authors agree that rigorous patient selection is logical and mandatory. Drug-induced sleep endoscopy (DISE) was introduced in 1991 and has been rediscovered and used extensively since the 2000s. It mimics sleep in order to observe the upper airway on flexible endoscopy. A review of the DISE literature was performed, and is reported in two parts. The present first part describes the technique: drugs, practical anesthesiologic and ENT modalities, reproducibility, and limitations...

The medicinal plant Tripterygium wilfordii (Celastraceae) contains a pair of class II diterpene synthases (diTPS) of specialized labdane-type metabolism that, despite remarkably close homology, form strikingly different products. TwTPS21 catalyzes bicyclization of the linear C20 precursor geranylgeranyl diphosphate to ent-copal-8-ol diphosphate, while TwTPS14 forms kolavenyl diphosphate. To determine the amino acid signature controlling the functional divergence of the homologues, we modeled their structures based on an existing crystal structure of the Arabidopsis ent-copalyl diphosphate synthase, archetypal of diTPSs in general metabolism of gibberellin phytohormones...

Central nervous system (CNS) involvement in systemic B-cell non-Hodgkin lymphoma (B-NHL) at diagnosis (sysCNS) is rare. We investigated the outcome of 21 patients with sysCNS, most commonly diffuse large B-cell lymphoma, treated with high dose methotrexate (HD-MTX) and R-CHOP. The median number of cycles of HD-MTX and R-CHOP was 4 (range 1-8) and 6 (range 0-8), respectively. Consolidative whole brain radiotherapy (WBRT) was given to 33% (7/21) patients. With a median follow-up of 44 months the 3-year progression free survival (PFS) and overall survival (OS) were 45% (95%CI 34-56%) and 49% (95%CI 38-60%), respectively...

The use of kaurane diterpenes as substrates in fungal biotransformation to achieve bioactive compounds has been widely reported. In this work, the natural product kaurenoic acid, a diterpene widely distributed in the plant Kingdom, was chemically converted into ent-15α-hydroxy-kaur-16-en-19-oic acid (1). Substrate 1 was subjected to biotransformation by the fungus Fusarium proliferatum, furnishing a new derivative, ent-2α,15α-dihydroxy-kaur-16-en-19-oic acid (2). The structure of metabolite 2 was deduced on the basis of spectroscopy and MS data...

Partitioning of ATP generation between glycolysis and oxidative phosphorylation is central to cellular bioenergetics but cumbersome to measure. We describe here how rates of ATP generation by each pathway can be calculated from simultaneous measurements of extracellular acidification and oxygen consumption. We update theoretical maximum ATP yields by mitochondria and cells catabolizing differ- ent substrates. Mitochondrial P/O ratios are 2.73 for oxidation of pyruvate plus malate and 1.64 for oxidation of succinate...
