Abstract Heterostructured Dye Sensitized Zeolite nanocomposites (Dye sens ZEO) were successfully prepared by an ultrasonication method. The structural analyses of the heterogeneous catalyst were confirmed using various characterization techniques such as XRD, FT-IR, SEM, UV-DRS, PL, EDX, and Mapping. From the studies of FT-IR, EDX and SEM, the good binding between dye molecule and zeolite was confirmed. The SEM studies revealed that the prepared material in cubic morphology. The Dye sens ZEO nanocomposite participated to photodegradation process of levofloxacin (LVF) drug which was examined by UV visible spectroscopy. It shows that greatest photocatalytic activity within 60 mins under visible light irradiation. The identification of degradation intermediates of LVF using GC-MS spectroscopy. The dye molecules contain azo group and zeolite consist absorption properties were very useful for the transformation of electron which were enhanced the photocatalytic activity. In scavenger studies, hydroxide radical play a superior role in the photodegradation mechanism. Finally, the photocatalyst pick up from the degraded solution using centrifugation method and used to further cycle.

The treatment of leachate by vegetative filters composed of short-rotation willow coppice (SRWC) has been shown to be a cost-effective alternative to conventional and costly methods. However, few studies have considered the treatment capability of willow filters at a scale large enough to meet the industrial requirements of private landfill owners in North America. We report here on a field trial (0.5 ha) in which a willow plantation was irrigated with groundwater (D0) or aged leachate at two different loadings (D1 and D2, which was twice that of D1). Additionally, half of the D2-irrigated plots were amended with phosphorus (D2P). The system, which operated for 131 days, was highly efficient, causing the chemical oxygen demand concentration to drop significantly with the total removal of ammonia (seasonal average removal by a concentration of 99–100%). D2P efficacy was higher than that of D2, indicating that P increased the performance of the system. It also increased the willow biomass 2.5-fold compared to water irrigation. Leaf tissue analysis revealed significant differences in the concentrations of total nitrogen, boron, and zinc, according to the treatment applied, suggesting that the absorption capacity of willows was modified with leachate irrigation. These results indicate that the willow plantation can be effective for the treatment of landfill leachate in respect of environmental requirements.

Taste is a sensory modality crucial for nutrition and survival, since it allows the discrimination between healthy foods and toxic substances thanks to five tastes, i.e., sweet, bitter, umami, salty, and sour, associated with distinct nutritional or physiological needs. Today, taste prediction plays a key role in several fields, e.g., medical, industrial, or pharmaceutical, but the complexity of the taste perception process, its multidisciplinary nature, and the high number of potentially relevant players and features at the basis of the taste sensation make taste prediction a very complex task. In this context, the emerging capabilities of machine learning have provided fruitful insights in this field of research, allowing to consider and integrate a very large number of variables and identifying hidden correlations underlying the perception of a particular taste. This review aims at summarizing the latest advances in taste prediction, analyzing available food-related databases and taste prediction tools developed in recent years.

In the present paper we propose a novel blind docking protocol based on Autodock-Vina. The developed docking protocol can provide binding site identification and binding pose prediction at the same time, by a systematical exploration of the protein volume performed with several preliminary docking calculations. In our opinion, this protocol can be successfully applied during the first steps of the virtual screening pipeline, because it provides binding site identification and binding pose prediction at the same time without visual evaluation of the binding site. After the binding pose prediction, MM/GBSA re-scoring rescoring procedures has been applied to improve the accuracy of the protein–ligand bound state. The FRAD protocol has been tested on 116 protein–ligand complexes of the Heat Shock Protein 90 – alpha, on 176 of Human Immunodeficiency virus protease 1, and on more than 100 protein–ligand system taken from the PDBbind dataset. Overall, the FRAD approach combined to MM/GBSA re-scoring can be considered as a powerful tool to increase the accuracy and efficiency with respect to other standard docking approaches when the ligand-binding site is unknown.

Abstract Background People with disabilities experience significant health inequalities. In Malawi, where most individuals live in low-income rural settings, many of these inequalities are exacerbated by restricted access to health care services. This qualitative study explores the barriers to health care access experienced by individuals with a mobility or sensory impairment, or both, living in rural villages in Dowa district, central Malawi. In addition, the impact of a chronic lung condition, alongside a mobility or sensory impairment, on health care accessibility is explored. Methods Using data from survey responses obtained through the Research for Equity And Community Health (REACH) Trust’s randomised control trial in Malawi, 12 adult participants, with scores of either 3 or 4 in the Washington Group Short Set (WGSS) questions, were recruited. The WGSS questions concern a person’s ability in core functional domains (including seeing, hearing and moving), and a score of 3 indicates ‘a lot of difficulty’ whilst 4 means ‘cannot do at all’. People with cognitive impairments were not included in this study. All who were selected for the study participated in an individual in-depth interview and full recordings of these were then transcribed and translated. Results Through thematic analysis of the transcripts, three main barriers to timely and adequate health care were identified: 1) Cost of transport, drugs and services, 2) Insufficient health care resources, and 3) Dependence on others. Attitudinal factors were explored and, whilst unfavourable health seeking behaviour was found to act as an access barrier for some participants, community and health care workers’ attitudes towards disability were not reported to influence health care accessibility in this study. Conclusions This study finds that health care access for people with disabilities in rural Malawi is hindered by closely interconnected financial, practical and social barriers. There is a clear requirement for policy makers to consider the challenges identified here, and in similar studies, and to address them through improved social security systems and health system infrastructure, including outreach services, in a drive for equitable health care access and provision.

Despite constant significant advances, cardiovascular as well as more general outcomes of hemodialysis treatment remain unsatisfactory. The introduction of innovative 'high retention onset' membranes has led to the development of a new treatment modality called 'expanded hemodialysis' (HDx), which is the focus of this book. This new therapy is like

Myositis of the skeletal muscle is rarely seen as an extraintestinal manifestation of inflammatory bowel disease. We report a case of a 36-year-old man with ulcerative colitis who developed 3 episodes of steroid responsive myositis in a 4-month period. He presented with a blistering rash followed by pain and massive swelling in the right shoulder and lower extremities, with marked elevation in muscle enzymes. Diagnosis of myositis was made after a muscle biopsy, which showed neutrophilic infiltrate in the deep subcutaneous tissue and skeletal muscle. Review of the literature indicates only a few cases of myositis associated with ulcerative colitis, most of them during an acute exacerbation of the disease. However, the present patient had his first episode when the ulcerative colitis was in remission. Myositis in ulcerative colitis may present atypically, in particular mimicking pyomyositis. Clinicians should be aware of this unusual steroid-sensitive complication.

La vegetación de Chiapas se encuentra una Nota bibliográfica con 37 títulos de trabajos, que son de la mayor impoportancia para los que se interesen por la flora de este Estado. La lista que sigue es una adición, todavía incompleta, a la enumeración anterior. Por lo tanto, se omiten aquí trabajos citados por el doctor Miranda, que se refieren en particular en Chiapas.
