BACKGROUND: Preliminary evidence indicates that the addition of low dose TBI (2-4 Gy) to reduced intensity conditioning may reduce the rate of relapse in allogeneic stem cell transplants. In very high risk patients receiving combination haploidentical-single unit cord blood transplants, we have added 4 Gy TBI to the widely used fludarabine, melphalan conditioning regimen, in hopes of reducing relapse and decreasing graft rejection. METHODS: We retrospectively reviewed the posttransplant outcomes of patients who underwent haplo-cord SCT between May 2013 and March 2015 and who received fludarabine 30mg/m2 D-7 to -3, melphalan 140mg/m2 D-2, and 2 Gy TBI D-4 and -3...

INTRODUCTION: Pituitary surgery involving different techniques is often applied to the excision of benign adenomas. Operative interventions involved various approaches and techniques. Endoscopic transsphenoidal approach is the less traumatic route to the sella turcica, avoiding brain retraction, and also permitting good visualization, with lower rates of morbidity and mortality. Although mortality of pituitary surgery decreased by advances in surgical techniques morbidities such as synechiae formation, anosmia, bleeding, nasal septal perforations, drying, and incrustation due to traumatization of the nasal structures such as septum, nasal mucosa, and middle concha are the current problems in pituitary surgery...

Oil-water separation has recently become an important subject due to the increasing incidence of oil spills. Materials with underwater superoleophobic properties have aroused considerable interest due to their cost-effectiveness, environmental friendliness and anti-fouling properties. This paper presents a robust salt-tolerant superoleophobic aerogel inspired by seaweed used without any further chemical modification for oil-seawater separation. The green aerogel is prepared by freeze-drying of sodium alginate (SA)-nanofibrillated cellulose (NFC) using Ca(2+) ions as the crosslinking agent...

Dried citrus peel derived from Citrus reticulata, also called "chenpi", possesses a complex mixture of flavonoids and has a history of traditional use to treat a variety of digestive disorders. We compared three sources of conventional chenpi from California (USA), Guangxi, Zhejiang, and two sources of "nchenpi", which contain greater nobiletin content, from Sichuan and Xinhui (China). Xinhui orange peel extract (OPE) had highest content of polymethoxylated flavones, along with greatest capacity to scavenge 2,2-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS), 2,2-diphenyl-1-pcrylhydrazyl (DPPH), and 2,2'-azobis-2-methyl-propanimidamide, dihydrochloride (AAPH) radicals and nitric oxide (NO)...

Since the appearance of recombinant human growth hormone (rhGH) in the 80's, its expansion and acquisition through the black market has increased, so the detection of its abuse continues to be a challenge at present. New biomarkers that are more reliable and sensitive, allowing a larger detection window, are still needed. In this line, Fibronectin 1 (FN1) has been proposed as potential genetic and protein biomarker of rhGH abuse in peripheral blood lymphocytes, serum and plasma. However, logistic problems associated with current blood collection in sports drug testing points towards potential new alternative matrices that could be good candidates to be evaluated...

Enantio- and stereoselective cyclopolymerization of hexa-1,5-diene was achieved by enantiomerically pure dichloro zirconium(IV) pre-catalysts 2 possessing chiral [OSSO]-type bis(phenolate) ligands (-)-1 and (+)-1 in combination with dried methylaluminoxane (dMAO) as an activator. The corresponding activities were recorded with quite high values up to 1,960 g mmol(2)(-1) h(-1) , which are extremely larger than those of the related complexes. The microstructure analysis for the PMCPs furnished by pre-catalysts (Λ,S,S)-2 and (Δ,R,R)-2 showed good isotacticity factors (α = 75-78%) and relatively high proportions of trans-cyclopentane rings (σ = 14-21%)...

The inhalatory route has emerged as an interesting non-invasive alternative for drug delivery. This allows both pulmonary (local) or systemic treatments (via alveolar absorption). Further advantages in terms of stability, dose and patient preference have often lead researchers to focus on dry powder inhaler delivery systems. Atenolol is an antihypertensive drug with low oral bioavailability and gastrointestinal side effects. Because atenolol possesses adequate permeation across human epithelial membranes, it has been proposed as a good candidate for inhalatory administration...

We evaluated the applicability of a validated GC-MS method for the determination of gabapentin in dried blood spots (DBS). Important for the acceptance of DBS sampling as an alternative sampling strategy is the possibility to base solid conclusions on the quantification. Therefore, bridging studies -studies in which the correlation between both DBS and a reference matrix (e.g. serum) is evaluated statistically- need to be conducted. To this end, a comparative study was set up to quantify gabapentin in both blood (DBS) and serum samples...

Allocation of liver grafts triggers emotional debates, as those patients, not receiving an organ, are prone to death. We analyzed a high MELD cohort (lab MELD≥30, n=100, median lab MELD of 35 (IQR: 31-37) of liver transplant recipients at our center over the last ten years, and compared results with a low MELD group, matched by propensity scoring for donor age, recipient age and cold ischemia. Endpoints of our study were cumulative post-transplant morbidity, cost, and survival. Six different prediction models, including D-MELD, Delta MELD, DRI, SOFT, BAR, and UCLA-FRS, were applied in both cohorts to identify risk for poor outcome and high cost...

Desiccation resistance, the ability of an organism to reduce water loss, is an essential trait in arid habitats. Drought frequency in tropical regions is predicted to increase with climate change, and small ectotherms are often under a strong desiccation risk. We tested hypotheses regarding the underexplored desiccation potential of tropical insects. We measured desiccation resistance in 82 ant species from a Panama rainforest by recording the time ants can survive desiccation stress. Species' desiccation resistance ranged from 0...

OBJECTIVES: Goat whey, a usually discarded byproduct from goat cheese manufacturing, is a good source of sialic acid (SA), an oligosaccharide that is involved in processes such as memory and brain excitability. Here, we investigated in rats the effect of dried goat whey (DGW) on memory and the brain excitability-dependent phenomenon known as cortical spreading depression (CSD). We also provide evidence for the involvement of SA in this effect. In addition, we tested animals under unfavorable suckling conditions to evaluate whether nutritional deficiency would modulate DGW action...
