Characterization of cervid skin tissues with chronic wasting disease by Raman spectroscopy and machine learning

Chronic wasting disease (CWD) is a contagious neurological disease in cervids that belongs to transmissible spongiform encephalopathies (TSEs). Its spread has threatened the healthy growth of wild and farm-raised deer and resulted in adverse population-level impacts. It also raised concerns over the possibility of infecting human beings like bovine spongiform encephalopathy (BSE). CWD is a prion disease that may take as long as two years for visible signs of the disease to appear. Currently, diagnostic tests approved for official CWD are postmortem tests (immunohistochemistry (IHC) and ELISA) which are not suitable for in vivo diagnosis. Raman spectroscopy offers a potential approach to detect and diagnose CWD rapidly in real time as a first screen onsite. With the Raman spectral data, machine learning algorithms could be utilized to extract meaningful information to differentiate the spectroscopic features that underline the signatures associated with the diseases effectively, even with a low signal-to-noise ratio (SNR) Raman spectral data acquired with a portable Raman spectrometer. In this study, in order to evaluate the effectiveness of Raman spectroscopy on CWD diagnosis, Raman spectra were collected by a Raman microscope as well as a portable Raman spectrometer from cervid skin tissue samples collected from both healthy (i.e., control, CWDnegative) and diseased (i.e., CWD-positive) cervids. The spectral data were classified by two machine learning algorithms, support vector machine and artificial neural network. The results suggested that Raman spectroscopy in conjunction with Machine learning can indeed offer a rapid first screening for CWD, with the highest accuracy of 94.4%. It has the potential to become a useful tool for in-field diagnosis and detection of CWD.

Visualizing Covalency and Multiple Bonds in Terms of the Electronic Single-Particle Density Matrix

Two-dimensional cuts through spin-integrated single-particle density matrices (SPDMs) have proven to be a valuable tool to discuss the nature of chemical bonding independent of the degree of rotation of the underlying orbitals in Hilbert space. Starting from a straightforward concept for the interpretation of σ bonds, we briefly present how the transition from purely ionic to mainly covalent bonding is mirrored in the off-diagonal features of the SPDM in the isoelectronic series LiF, BeO and BN. Furthermore, we outline one of several possible ways to extend the graphical representation and interpretation of SPDMs to the case of π bonds in organic molecules and apply it to the conjugated π-electron system 1,6-hexadiynediol.
Satisfaction with nursing care and its related factors in patient with COVID-19

Background: Patients’ satisfaction is a fundamental factor in the quality of nursing care. The emergence of the novel coronavirus (COVID-19) and the highly contagious virus can affect nursing care by increasing the number of care-seekers. This study aimed to determine the patients’ satisfaction and related factors in patients with COVID-19 hospitalized in Taleghani Hospital, Urmia-Iran, in 2020.Methods: This descriptive correlational study was conducted on 196 patients with COVID-19 hospitalized in Taleghani Hospital, Urmia. Purposive convenient sampling was used to recruit participants. Study participants completed Patient Satisfaction Instrument (PSI) and demographics questionnaires. Data were analyzed with SPSS software version 25.0. Results: The majority of patients (68.9%) were moderately satisfied with nursing care. Based on Pearson Correlation Analysis, only residential status had a significant inverse relationship with satisfaction level in patients with COVID-19 (r = -0.0238, P=0.001). Conclusion: The patients’ satisfaction with nursing care was mostly at a moderate level. Thus, there is a need to educate health personnel and nurses in particular and motivate them to have active participation in achieving patients’ satisfaction with COVID-19. Notably, only the institutes that take patients’ satisfaction as a top priority can succeed in a competitive market of health services.
Black-Start and Service Restoration in Resilient Distribution Systems With Dynamic Microgrids

The resilience of distribution systems has been challenged by power outages caused by natural disasters, which calls for novel solutions to system restoration. However, the existing black-start (BS) techniques are mainly developed at the transmission level. This problem can be resolved by adopting dynamic microgrids (MGs), i.e., MGs with dynamic and adjustable boundaries nested in the distribution systems. This article proposes a restoration procedure that adopts self-organizing inverters as BS units and achieves distribution system restoration in the context of dynamic MGs. The proposed restoration procedure is structured as a two-stage approach and designed to restore a complete blackout distribution system to the state where the system is ready for seamless main grid reconnection. A framework of dynamic MG operation is developed, which improves the self-healing capability of off-grid distribution systems with automatic sectionalization and flexible reconfiguration. A sequence of actions during restoration is defined, along with distributed controllers designed with considerations of practical operating challenges. The proposed restoration procedure is validated on a 34-bus system using real-time hardware-in-the-loop simulation.
Differential sensitivity to ethylene of the various ripening pathways of ethylene-suppressed cantaloupe melons

The availability of ethylene-suppressed transgenic melon fruit harboring an ACC oxidase gene in antisense orientation (Ayub et al., 1996) allowed to discriminate between ethylene-dependent and ethylene-independent ripening pathways. It has been observed that pulp coloration, accumulation of sugars, and loss of acidity are ethylene independent processes, whereas rind yellowing, flesh softening, development of the peduncular abscission (Guis et al., 1997), aroma production (Bauchot et al., 1998) and respiratory burst (not published) are ethylene dependent. The present study is aimed at characterizing the sensitivity to ethylene of softening of the flesh and yellowing of the rind by treating ethylene-suppressed melons with ethylene. The kinetics of changes have been followed under various ethylene concentrations and upon transfer to air. This has allowed an estimation of the threshold levels of ethylene required for initiating the processes and the saturating levels for full velocity. The effects of the cessation of the ethylene treatment have also been determined.

Background: Non-adherence to anti-hypertensive medications is a modifiable risk factor for uncontrolled hypertension. Despite the availability of tolerable anti- hypertensive drugs, majority of patients are still not adherent to their medications. Aim: To investigate Socio-demographic profile, lifestyle changes and comorbid ailments as predictors of medication Adherence among hypertensive patients attending Federal Teaching Hospital, Ido-Ekiti, Southwestern, Nigeria. Methods: Hospital-based cross-sectional study was conducted on 356 hypertensive patients on follow up. Systematic random sampling technique was adopted to recruit the 356 respondents. Semi-structured interviewer administered questionnaire was employed to seek information on respondents’ socio-demographic characteristics, lifestyle changes, comorbid ailments, and number of antihypertensive medications. Adherence level was determined using the Morisky’s Medication Adherence Scale. Data was analyzed using SPSS 20. Multivariate logistic regression analysis was used to identify the predictors of medication adherence. Results: The prevalence of medication adherence was 60.4%. In multivariate analysis; male gender (OR, 15.85, 95% CI: 4.33 – 58.11) level of education (OR, 16.94, 95% CI: 1.13 – 253.06) habits of salt usage (OR, 284, 95% CI: 29.35 – 2748.37) and two anti-hypertensive drugs (OR, 15.13, 95% CI: 4.78 – 47.867) were the predictors of good medication adherence. On the other hand, trading (OR, 0.13, 95% CI: 0.02 – 0.78) was associated with poor medication adherence. Conclusion: The prevalence of medication adherence was low. Trading was the predictor of poor medication adherence. Therefore, clinicians and other stakeholders should target this set of occupation and provide qualitative health education to improve their medication adherence level.
Bright Green Emitting Maltodextrin Coated Cadmium Sulfide Quantum Dots as Contrast Agents for Bioimaging: A Biocompatibility Study

The biological characteristics and physicochemical properties of quantum dots (QDs) pose new challenges in understanding, predicting, and managing their potential adverse health effects following exposure. The safe use of QDs in biomedicine requires a detailed understanding of their biocompatibility and toxicity. This study evaluates the biocompatibility of maltodextrin coated cadmium sulfide quantum dots in rodents. The in vivo localization of maltodextrin coated cadmium sulfide QDs in tissues was studied under fluorescence microscopy, and their biocompatibility was assessed through a histopathological analysis and biochemical assays. Animals treated daily with 200 μg/Kg of maltodextrin coated cadmium sulfide QDs for either 5 days or 15 days showed a differential presence of quantum dots in their organs. Intense fluorescence was detected in kidney, liver; muscle and brain, with moderate fluoresce detected in intestine, lung, and testis. The histopathological and biochemical analyses showed that QDs were non-toxic for rodents. The in vivo analysis revealed the distribution pattern of QDs and their biocompatibility with all tissues analyzed. The bright green emitting of maltodextrin coated cadmium sulfide QDs suggests they might be used as contrast agents for bio-imaging applications.

Rapid and simple determination of multi-elements in aerosol samples collected on quartz fiber filters by using EDXRF coupled with fundamental parameter quantification technique

ABSTRACTIt would be convenient if we could achieve multi-component (organic and inorganic species) analysis using just one quartz fiber filter (QFF) as an aerosol collection medium. In general, QFF have been used for analyzing carbonaceous materials in aerosols. This study shows a nondestructive, rapid, and simple method using EDXRF (Energy Dispersive X-Ray Fluorescence spectrometry) that has secondary targets and three-dimensional polarization optics for analyzing inorganic multi-elements in aerosols collected on QFFs. Multi-element analysis can be achieved by using EDXRF coupled with fundamental parameter (FP) quantification, as speed of up to 900 s (15 min) per sample. The EDXRF-FP method shows good repeatability, with generally less than 5% variation when measuring each analyzed element. While the elemental concentrations in the blank QFFs in any lots examined in this study could be considered to be lower than the actual samples, the blank level of Ni cannot be ignored. The EDXRF-FP results for each element of the aerosols collected on QFF agreed well with ICP-MS and ICP-AES results. The temporal variations of the selected elements in aerosols obtained by EDXRF-FP showed very good agreement with those obtained by ICP-MS and AES, and thus this method is suitable for elucidating day-to-day variations of multi-elements in aerosols.

Menopausal Hormone Therapy - Pros and Cons

Menopausal hormone therapy (MHT) is surrounded by controversies after the revolutionary reports from Women’s Health Initiative (WHI) trial in 2002. The universal hormone therapy (HT) policy used before WHI became obsolete after 2002. Majority of women who were already taking MHT discontinued the therapy worldwide. Even practitioners stopped prescribing MHT. Several studies have suggested a “timing hypothesis” or a “window-of-opportunity” for the initiation of MHT, which is early after menopause. This means that MHT is best given immediately postmenopause for a short duration of time. MHT started many years is best given immediately postmenopause for a short duration of time. MHT started many years after menopause and given for long duration following menopause has more side effects. The use of MHT decreased drastically after the results of these two studies were published. However, due to Danish Osteoporosis Prevention Study and the Kronos Early Estrogen Prevention Study, interest has been generated in MHT due to beneficial results of MHT. Excellent symptom relief can be provided by MHT for healthy women who experience menopausal symptoms. MHT poses a low risk in these healthy women with no comorbidities. With regard to cardiovascular diseases and osteoporosis, not giving MHT in symptomatic women may pose a risk. When MHT is initiated in elderly women and in those with comorbidities, it may be associated with increased risk. Prior discussion with patient about HT is a must before starting MHT. Personalized discussion with patient about symptoms, treatment goals, analysis of age, time since menopause, and consideration of comorbidities influences decision-making about starting MHT. We recommend further studies on MHT for better understanding of risk versus benefit of MHT.
Facile synthesis of a biocompatible silver nanoparticle derived tripeptide supramolecular hydrogel for antibacterial wound dressings

Realizing the widespread demand for biocompatible supramolecular hydrogel based wound dressings, we have developed an N-terminally 2(naphthalen-6-yl)acetic acid (Nap) protected Phe–Phe–Cys peptide (Nap-FFC) using a liquid phase method. This Nap-FFC peptide was used to design a supramolecular hydrogel via a self-assembling process. The Nap-FFC short peptides produced stable and transparent silver nanoparticle-based hydrogels (AgNPs@Nap-FFC) wherein the self-assembled Nap-FFC nanofibers acted as scaffolds for the mineralization of silver nanoparticles (AgNPs) and stabilizers of the synthesized AgNPs. The resultant AgNPs@Nap-FFC nanocomposites were characterized using ultraviolet-visible spectrophotometry (UV-vis spectroscopy), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDX) studies. The AgNPs@Nap-FFC nanocomposites showed excellent monodispersity, long term stability, and functional flexibility in comparison to other AgNP based nanocomposites. Furthermore, AgNPs@Nap-FFC exhibited strong inhibition against both Gram-positive (methicillin-resistant Staphylococcus aureus) and Gram-negative (Acinetobacter baumannii) bacteria and, most importantly, they showed favorable biocompatibility towards human cervical carcinoma cells (HeLa cells). Hence, this study implies that AgNPs@Nap-FFC nanocomposites can easily be prepared in a cost-effective manner and can be used effectively for future antibacterial wound dressings.
