Dairy farm manure and effluent are applied to cropland in China to provide a source of plant nutrients, but there are concerns over its effect on nitrogen (N) leaching loss and groundwater quality. To investigate the effects of land application of dairy manure and effluent on potential N leaching loss, two lysimeter trials were set up in clayey fluvo-aquic soil in a winter wheat-summer maize rotation cropping system on the North China Plain. The solid dairy manure trial included control without N fertilization (CK), inorganic N fertilizer (SNPK), and fresh (RAW) and composted (COM) dairy manure...

PURPOSE: Airway clearance is an essential part of the management of cystic fibrosis (CF) as it facilitates clearance of viscous pulmonary secretions. This review aimed to determine the effect of autogenic drainage (AD) and assisted autogenic drainage (AAD) compared with no, sham, or other types of airway clearance in children with CF. SUMMARY OF KEY POINTS: Two pediatric randomized cross-over trials were identified on the use of AD in children with CF; no studies were available on the use of AAD...

Conducting Bridge Random Access Memory (CBRAM) is one of the most promising candidates for future non-volatile memories. It is important to understand the scalability and retention of CBRAM cells to realize better memory performance. Here we directly observe the switching dynamics of Cu tip/SiO2/W cells with various active electrode sizes using in-situ transmission electron microscopy. Conducting filaments (CFs) grow from the active electrode (Cu tip) to inert electrode (W) during the SET operations. The size of the Cu tip affects the electric-field distribution, the amount of the cation injection into electrolyte, and the dimension of the CF...

The homoleptic compound [PPh₄][CF₃AuCF₃] cleanly undergoes photoinduced oxidative addition of CF₃I to afford the organogold(III) derivative [PPh₄][(CF₃)₃AuI] in good yield and under mild conditions. This compound provides a convenient entry to the chemistry of the perfluorinated (CF₃)₃Au fragment whose properties are analyzed with the aid of DFT methods and compared with those of the homologous non-fluorinated (CH₃)₃Au moiety. It is found that reductive elimination of CX₃-CX₃ in the former (X = F) requires a much higher energy barrier than in the latter (X = H) and is therefore considerably less favored...

The publication of the WHO Infant and Young Child Feeding (IYCF) indicators in 2008 equipped the nutrition and broader development community with an invaluable tool for measuring, documenting, and advocating for faster progress in improving these practices in low- and middle-income countries (LMICs). The indicators, with 5 of them focusing on complementary feeding (CF) practices, were originally designed for population level assessment, targeting, monitoring, and evaluation. This chapter takes stock of where we are with the existing CF indicators: it reviews how the indicators have been used, what we have learned, and what their strengths and limitations are, and it suggests a way forward...

The WHO infant feeding guidelines, including those for complementary feeding (CF), are very prescriptive, largely based on the outcomes of exclusive breastfeeding, and have a bias towards undernutrition. Consideration of longer-term outcomes related to overnutrition, the predominant nutrition problem in affluent countries, is limited. Compared to the ongoing and often zealous debates regarding the short- and long-term benefits of exclusive breastfeeding to 6 months in affluent countries, exposures (particularly feeding practices) and outcomes related to CF, independent of exclusive breastfeeding, have received little attention...

The antimicrobial activity and toxicity to nematodes of the cyclam salt [H2{H2((4-CF)3PhCH2)2Cyclam}](CH3COO)2.(CH3COOH)2 was evaluated. Estimated minimum inhibitory concentrations (MICs) of 9, 261 and 15 µg/mL were obtained for Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus, respectively. For selected Candida spp., the estimated MICs obtained ranged from 32 µg/mL to 63 µg/mL. Bactericidal activity was demonstrated but the compound was not reliably fungicidal. Concentrations of the cyclam salt up to 32 µg/mL did not significantly affect survival of the nematode Caenorhabditis elegans; however, concentrations equal or above this value significantly affected nematode survival in a dose-dependent manner...

Upon cardiac pathological conditions such as ischemia, microenvironmental changes instruct a series of cellular responses that trigger cardiac fibroblasts-mediated tissue adaptation and inflammation. A comprehensive model of how early environmental changes may induce cardiac fibroblasts (CF) pathological responses is far from being elucidated, partly due to the lack of approaches involving complex and simultaneous environmental stimulation. Here, we provide a first analysis of human primary CF behavior by means of a multi-stimulus microdevice for combined application of cyclic mechanical strain and controlled oxygen tension...

Zahra N Sayyid, Zachary M Sellers
Cystic fibrosis (CF), the most common autosomal recessive lethal disease in Caucasians, causes chronic pulmonary disease and can lead to cor pulmonale with right ventricular dysfunction. The presence of the cystic fibrosis transmembrane conductance regulator (CFTR) in cardiac myocardia has prompted debate regarding possible defective ion channel-induced cardiomyopathy. Clinical heart disease in CF is considered rare and is restricted to case reports. It has been unclear if this is due to the lack of physiological importance of CFTR in the heart, the relatively short lifespan of those with CF, or a technical inability to detect subclinical disease...

Safety-data for lumacaftor/ivacaftor (LUM/IVA) combination therapy in patients with severe lung disease (percent predicted forced expiratory volume in 1s [ppFEV1] <40) remain limited. We report immediate post-dose respiratory-related adverse events in 12 patients with severe cystic fibrosis (CF) lung disease (median [IQR] ppFEV1: 34 [31-36]) prescribed LUM/IVA. All patients experienced a decline in ppFEV1 from baseline at 2-hours (median [IQR] relative change: -19 [-21 to -11]%, p<0.001) that persisted at 24-hours but recovered in most patients at 1-month...

In search of an effective and less toxic absorption enhancer, we synthesized primary amine acetylation of generation 2 polyamidoamine (G2 PAMAM) dendrimer (Ac-G2) by the reaction of G2 PAMAM dendrimer with acetic anhydride, and evaluated the effects of Ac-G2 on the intestinal absorption of poorly absorbable water-soluble drugs using an in situ closed-loop method in rats. The results indicated that Ac50-G2 had a greatest absorption enhancing effect for 5(6)-carboxyfluorescein (CF) in various acetylation levels of G2 PAMAM dendrimers...

Infants are born equipped to ingest nutrients, but because of the transitions in the mode of feeding in the first years (from "tube" feeding in utero to eating table foods with the family), they have to learn how, what and how much to eat. Eating behavior established during early years may follow throughout childhood; therefore, it is fundamental to understand the most important drivers of the early development of eating behavior. Beyond the first flavor discoveries during the gestational and lactation periods (through the infant's exposure to flavors from foods of the mother's diet), the most important phases for learning food preferences and appetite control may be the beginning of complementary feeding (CF)...

Cystic fibrosis (CF) airways harbour complex and dynamic polymicrobial communities that include many oral bacteria. Despite increased knowledge of CF airway microbiomes the interaction between established CF pathogens and other resident microbes and resulting impact on disease progression is poorly understood. Previous studies have demonstrated that oral commensal streptococci of the Anginosus group (AGS) can establish chronic pulmonary infections and become numerically dominant in CF sputa indicating that they play an important role in CF microbiome dynamics...

This study aimed to investigate the energy dependence and the angular dependence of commercially available optically stimulated luminescence (OSL) point dosimeters in the mammography energy range. The energy dependence was evaluated to calculate calibration factors (CFs). The half-value layer range was 0.31-0.60 mmAl (Mo/Mo 22-28 kV, Mo/Rh 28-32 kV, and W/Rh 30-34 kV at 2-kV intervals). Mo/Rh 28 kV was the reference condition. Angular dependence was tested by rotating the X-ray tube from -90° to 90° in 30° increments, and signal counts from angled nanoDots were normalized to the 0° signal counts...
