Authors: Ndlovu Ntombizodwa , Nelson Gill , Vorajee Naseema , Murray Jill 
Published: February 2016

BackgroundSouth African miners have a statutory right to autopsies for occupational lung disease compensation. These autopsies also provide information for research and surveillance.MethodsCardio‐respiratory organs are removed where miners die and are examined at the National Institute for Occupational Health. We extracted data from the PATHAUT database and described key demographic, exposure and disease trends (1975–2013).ResultsOf 109,101 autopsies, 72,348 (66.3%) were black, and 34,794 (31.9%) were white miners. Autopsies declined from over 3,000 (1975–1998) to 1,118 in 2013. Most were gold miners (74.0%). 78.6% black and 13.2% white miners died while in employment. Overall proportions of silicosis and pulmonary tuberculosis were 12.0% and 13.0% in black, and 20.5% and 2.4% in white miners, respectively. Disease increased over time.ConclusionsHigh levels of disease persist. Black ex‐miners are underrepresented, indicating a need for strategies to improve awareness and provision of autopsy facilities in labor‐sending areas. Am. J. Ind.

Highly permselective MIL‐68(Al)/matrimid mixed matrix membranes for CO2/CH4 separation
Authors: Dong Xinyu , Liu Qian , Huang Aisheng 
Published: February 2016

ABSTRACTWith global appeal to green and efficient utilization of energies, metal‐organic frameworks based mixed matrix membranes are standing out in applications such as gas and liquid separation because of the integration of size/shape selectivity of MOFs with processability and mechanical stability of polymers. In the present work, a novel MIL‐68(Al) (MIL = Material of Institute Lavoisier) based mixed matrix membrane (MMM) was developed by adding porous MIL‐68(Al) into Matrimid for the separation of CO2/CH4 mixture. The MIL‐68(Al)/Matrimid MMM displays a high CO2 permselectivity. For the separation of an equimolar CO2/CH4 mixture at 373 K and 1 bar, the CO2 permeability and the CO2/CH4 selectivity are 284.3 Barrer and 79.0, respectively, which far exceed the Robeson upper bound limit and those of the previously reported MMMs. Both the operation pressure and temperature have great influence to the separation performance of the MIL‐68(Al)/Matrimid MMM. Further, the MIL‐68(Al)/Matrimid MMM shows a high stability in the long‐term separation of CO2/CH4. These properties recommend the MIL‐68(Al)/Matrimid MMM as a promising candidate for the purification of natural gases. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43485.
Autoantibodies against homocysteinylated protein in a mouse model of folate deficiency‐induced neural tube defects

Published: February 2016

BackgroundPericonceptional supplementation with folic acid results in a significant reduction in the incidence of neural tube defects (NTDs). Nonetheless, NTDs remain a leading cause of perinatal morbidity and mortality worldwide, and the mechanism(s) by which folate exerts its protective effects are unknown. Homocysteine is an amino acid that accumulates under conditions of folate‐deficiency, and is suggested as a risk factor for NTDs. One proposed mechanism of homocysteine toxicity is its accumulation into proteins in a process termed homocysteinylation.Methods & ResultsHerein, we used a folate‐deficient diet in pregnant mice to demonstrate that there is: (i) a significant inverse correlation between maternal serum folate levels and serum homocysteine; (ii) a significant positive correlation between serum homocysteine levels and titers of autoantibodies against homocysteinylated protein; and (iii) a significant increase in congenital malformations and NTDs in mice deficient in serum folate. Furthermore, in mice administered the folate‐deplete diet before conception, supplementation with folic acid during the gestational period completely rescued the embryos from congenital defects, and resulted in homocysteinylated protein titers at term that are comparable to that of mice administered a folate‐replete diet throughout both the pre‐ and postconception period. These results demonstrate that a low‐folate diet that induces NTDs also increases protein homocysteinylation and the subsequent generation of autoantibodies against homocysteinylated proteins.ConclusionThese data support the hypotheses that homocysteinylation results in neo‐self antigen formation under conditions of maternal folate deficiency, and that this process is reversible with folic acid supplementation.

A fluorescent aptasensor for sensitive analysis oxytetracycline based on silver nanoclusters
Authors: Hosseini Morteza , Mehrabi Fatemeh , Ganjali Mohammad Reza , Norouzi Parviz 
Published: February 2016

AbstractA fluorescent aptasensor for detection of oxytetracycline (OTC) was presented based on fluorescence quenching of DNA aptamer‐templated silver nanoclusters (AgNCs). The specific DNA scaffolds with two different nucleotides fragments were used: one was enriched with a cytosine sequence fragment (C12) that could produce DNA–AgNCs via a chemical reduction method, and another was the OTC aptamer fragment that could selectively bind to the OTC antibiotic. Thus, the as‐prepared AgNCs could exhibit quenched fluorescence after binding to the target OTC. The fluorescence ratio of the DNA–AgNCs was quenched in a linearly proportional manner to the concentration of the target in the range of 0.5 nM to 100 nM with a detection limit of 0.1 nM. This proposed nanobiosensor was demonstrated to be sensitive, selective, and simple, introducing a viable alternative for rapid determination of toxin OTC in honey and water samples.

A novel analytical ultracentrifugation based approach to the low resolution structure of gum arabic
Authors: Gillis Richard B. , Adams Gary G. , Alzahrani Qushmua , Harding Stephen E. 
Published: February 2016

ABSTRACTUnder investigation are the structural properties of gum arabic, an industrially important biopolymer for use as a stabilizer or in drug delivery, using Analytical Ultracentrifugation—a well‐established, matrix‐free probe for macromolecular size and shape. These results are combined with chromatographically‐coupled methods (multi‐angle light scattering, differential press imbalance viscometry) to provide a global analysis of its structure in varying ionic strength conditions. This analysis indicates that gum Arabic may have a compact, elliptical structure in solution, the significance of which for biotechnological use is indicated. This modelling method can be applied to other biopolymers and synthetic polymers. © 2016 Wiley Periodicals, Inc. Biopolymers 105: 618–625, 2016.
Studies of the B‐Z transition of DNA: The temperature dependence of the free‐energy difference, the composition of the counterion sheath in mixed salt, and the preparation of a sample of the 5′‐d[T‐(m5C‐G)12‐T] duplex in pure B‐DNA or Z‐DNA form
Authors: Guéron Maurice , Plateau Pierre , Filoche Marcel 
Published: February 2016

ABSTRACTIt is often envisioned that cations might coordinate at specific sites of nucleic acids and play an important structural role, for instance in the transition between B‐DNA and Z‐DNA. However, nucleic acid models explicitly devoid of specific sites may also exhibit features previously considered as evidence for specific binding. Such is the case of the “composite cylinder” (or CC) model which spreads out localized features of DNA structure and charge by cylindrical averaging, while sustaining the main difference between the B and Z structures, namely the better immersion of the B‐DNA phosphodiester charges in the solution. Here, we analyze the non‐electrostatic component of the free‐energy difference between B‐DNA and Z‐DNA. We also compute the composition of the counterion sheath in a wide range of mixed‐salt solutions and of temperatures: in contrast with the large difference of composition between the B‐DNA and Z‐DNA forms, the temperature dependence of sheath composition, previously unknown, is very weak. In order to validate the model, the mixed‐salt predictions should be compared to experiment. We design a procedure for future measurements of the sheath composition based on Anomalous Small‐Angle X‐ray Scattering and complemented by 31P NMR. With due consideration for the kinetics of the B‐Z transition and for the capacity of generating at will the B or Z form in a single sample, the 5′‐d[T‐(m5C‐G)12‐T] 26‐mer emerges as a most suitable oligonucleotide for this study. Finally, the application of the finite element method to the resolution of the Poisson‐Boltzmann equation is described in detail. © 2016 Wiley Periodicals, Inc. Biopolymers 105: 369–384, 2016.

Published: February 2016

AbstractIn order to review the need assessment of enhancing the weightage of Applied Biochemistry in the undergraduate curriculum at Mahatma Gandhi Institute of Medical Sciences (MGIMS), Sevagram, a validated questionnaire was sent to 453 participants which include 387 undergraduate students, 11 interns, 23 postgraduate students, and 32 faculty members. A web‐based data collection and analysis tool was designed for online questionnaire distribution, data collection, and analysis. Response rate was 100%. Most of the respondents agreed that the subject Biochemistry has relevance in clinical practice (81.24%) and applied based learning of Biochemistry by medical undergraduates would help in overall improvement in the health standards/patients care (83.44%). According to 65.12% respondents, most of the medical undergraduates read Biochemistry just for examination purpose only. Nearly half of the respondents agreed that minute details of biochemical reactions were not much useful in clinical practice (53.86%) and the vast majority of diagrammatic cycles memorized by the medical undergraduates had no relevance in clinical practice (51.21%), the decreased interest in learning the Applied Biochemistry was due to more amount of clinically irrelevant information taught to medical undergraduates (73.51%), there was a need to rethink for removing the diagrammatic biochemical cycles from curriculum for medical undergraduates (48.12%), the less learning of Applied Biochemistry or competencies would affect the clinical skills and knowledge of medical undergraduates (70.42%). The result of this study suggests that there is need for restructuring the Biochemistry curriculum with more clinical relevance. © 2016 by The International Union of Biochemistry and Molecular Biology, 44:230–240, 2016.
Structure prediction and analysis of neuraminidase sequence variants
Authors: Thayer Kelly M. 
Published: February 2016

AbstractAnalyzing protein structure has become an integral aspect of understanding systems of biochemical import. The laboratory experiment endeavors to introduce protein folding to ascertain structures of proteins for which the structure is unavailable, as well as to critically evaluate the quality of the prediction obtained. The model system used is the highly mutable influenza virus protein neuraminidase, which is the key target in the development of therapeutics. In light of recent pandemics, understanding how mutations confer drug resistance, which translates at the molecular level to understanding how different sequence variants differ, constitutes an area of great interest because of the ramifications in public health. This lab targets upper level undergraduate biochemistry students, and aims to introduce tools to be used to explore protein folding and protein visualization in the context of the neuraminidase case study. Students proceed to critically evaluate the folded models by comparison with crystallographic structures. When validity is established, they fold a neuraminidase sequence for which a structure is not available. Through structural alignment and visual inspection of the 150 loop, students gain molecular insight into two possible conformations of the protein, which are actively being studied. Folding the third chosen sequence mimics a true research environment in allowing students to generate a structure from a sequence for which a structure was not previously available, and to assess whether their particular variant has an open or closed loop. From this vantage, they are then challenged to speculate about the connection between loop conformation and drug susceptibility. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(4):361–376, 2016.
Discussions about reproductive and sexual health among young adult survivors of cancer
Authors: Wang Ying , Chen Leo , Ruan Jenny Y. , Cheung Winson Y. 
Published: February 2016

AbstractFertility preservation and sexual health are increasingly important as more young cancer patients survive their disease. Our aims were to describe the frequency with which reproductive and sexual health discussions occur, and to identify clinical factors associated with these discussions. Medical records of patients aged 20–39 diagnosed with solid tumors from 2008–2010 who survived ≥2 years were retrospectively reviewed. Multivariate logistic models were used to explore the relationship between clinical factors and occurrence of discussions. We analyzed 427 survivors: median age was 35 years, 29% were men, 88% had baseline [Eastern Cooperative Oncology Group (ECOG)] ECOG 0, and 79% were in a relationship. Only 58% and 7% of patients received discussions about reproductive and sexual health, respectively, at their initial oncology consultation, most of which were led by medical oncologists. There was a significant association between reproductive and sexual health conversations, in that those who engaged in dialog about one topic were more likely to participate in discussions about the other (P = 0.01). Patients with gynecologic malignancies (P < 0.0001) were more inclined to engage in sexual health discussions. Only a minority (19%) of patients took specific action toward fertility preservation, but the receipt of reproductive health discussions was a strong and independent driver for pursuing fertility preservation (P < 0.0001). The impact of cancer and its treatment on fertility and sexual health was inadequately addressed at the time of diagnosis among young cancer survivors. This warrants specific attention since having reproductive health discussions was strongly predictive of patients pursuing fertility preservation strategies.
