Simultaneous determination of Cu(II), Zn(II), and Pb(II) from aqueous solutions using a polymer inclusion membrane (PIM) based-sensor with 1-(2-pyridylazo)-2-naphthol (PAN) as chromophore and chemometric methods
Authors: Mancilla-Rico Alejandro J. , Rodríguez de San Miguel Eduardo 
Published: September 2022

Polymer inclusion membranes (PIMs) are developed to be used as colorimetric sensors for the simultaneous determination and quantification of Cu(II), Zn(II), Pb(II) from aqueous solutions using chemometric methods. Different physical and chemical factors that influence the detection process of the analytes are studied, i.e., the concentration of the metal cation, the amount of membrane, and the pH of the solution. The most significant variables within the detection process in membrane sensors are those that are closely related to the chemical reaction of the detection, that is, the concentration of the metal cation and the number of active sites available in the optomembrane. The reversibility and durability of the signal are evaluated as well. The optomembrane reaches 95% of the optical signal attributed to the process of formation of the different colorful complexes in 20 min, regardless of the metal cation. The optomembrane of CTA—TEHP—PAN presents a very narrow linear interval of response to the concentration of the cations, Zn(II) and Cu(II) ranging from 0.6 to 6 ppm; for higher concentrations the polymeric detector presents saturation. The response of the sensor to different concentrations of Pb(II) is not linear, which can be attributed to the lack of chemical affinity to generate the complex in the polymer film. The simultaneous determination of the three metal cations by three chemometric methods [multivariate curve resolution (MCR), artificial neural networks (ANNs) and partial least squares (PLS)] is performed with an experimental central composite design matrix at five levels and three experimental factors. The construction of the quantification model is carried out from the information obtained from the VIS spectrum of the PIMs exposed to the aqueous solutions. The predictive power of the quantification models for each of the metal cations is evaluated contemplating the determination coefficient (R2) and the root mean square error (RMSE) values. Results favors the use of the PLS algorithm, although due to the competition for the actives sites of the chromophore, Pb(II) determination is not satisfactorily acomplished. Principal component analysis (PCA) is in addition employed to visualize patterns in the synthesized membranes.

AimThis study aimed to explore athletes' experiences and opinions of communication strategies in applied sports nutrition, as well as capture suggestions for future mobile app supportive solutions.MethodsA qualitative approach was used for this research. Data was generated from semi-structured focus groups (n = 9) with a purposive sample of 41 (male = 24, female = 17) full time professional athletes (mean age 24 ± 4.59) from five sports (football, rugby union, athletics, cycling, and boxing). Data was analyzed using reflexive thematic analysis.ResultsThe analysis identified four higher order themes and five sub themes. Athletes appear dissatisfied with the levels of personalization in the nutrition support they receive. Limited practitioner contact time was suggested as a contributing factor to this problem. Athletes acknowledged the usefulness of online remote nutrition support and reported a desire for more personalized technology that can tailor support to their individual needs.ConclusionAthletes experienced a hybrid human-computer approach that combines in-person and remote digital methods to communicate with and receive information from practitioners. Mobile technology may now afford sports nutritionists with new opportunities to develop scalable solutions to support practice.

ObjectiveTo compare the clinical efficacy and radiological outcomes of 3-level anterior cervical discectomy and fusion (ACDF) and open-door laminoplasty (LP).MethodsA total of 74 patients from January 2017 to January 2020 were enrolled in this retrospective study. There were two groups. Group A (30 cases) received 3-level ACDF, while Group B (44 cases) received open-door LP. Clinical evaluation included perioperative parameters, Neck Disability Index (NDI), and Japanese Orthopaedic Association (JOA) scores. Radiological evaluation included cervical curve depth (CCD), C2–7 angle, C2–7 sagittal vertical axis (cSVA), C7 slope (C7S), and T1 slope (T1S).ResultsPerioperative parameters such as blood loss, drainage volume after surgery, and hospital stay of patients in Group A were significantly less than those in Group B (P &lt; .001). NDI scores decreased and JOA scores increased significantly after surgery in both groups (P &lt; .05). There was a significant difference in both scores postoperatively and at 1 month after surgery between the two groups (P &lt; .05). CCD and C2–7 angle of Group A increased significantly postoperatively at 1 month after surgery and at final follow-up (FFU) (P &lt; .05). There was a significant difference in CCD and the C2–7 angle between the two groups postoperatively at 1 month after surgery and at FFU (P &lt; .05). T1S increased significantly in Group A postoperatively and at 1 month after surgery (P &lt; .05).Conclusion3-level ACDF and open-door LP achieved favorable clinical outcomes and ACDF benefited patients in the early stage of rehabilitation. Compared with open-door LP, 3-level ACDF had advantages of reconstructing cervical lordosis with increased CCD and C2–7 angle.

Published: September 2022

BackgroundSpontaneous regression of primary liver cancer is a rare event, and currently the exact pathogenesis of spontaneous tumor regression remains unclear.Case descriptionClinical information was collected from a patient with spontaneous regression of liver cancer at our center. The patient was a 41-year-old male. He was admitted to the hospital on 3 May 2019, due to aversion to fatty or greasy food, anorexia, loss of appetite, and abdominal distension. Laboratory examination results included hepatitis B surface antigen positivity, hepatitis B e antigen positivity, and hepatitis B core antibody positivity and tumor marker levels of alpha-fetoprotein 142,938.20 µg/L, abnormal prothrombin 4,599.91 mAU/ml, and carbohydrate antigen 19–9 82.05 U/ml. Upper abdominal enhanced computed tomography indicated right hepatocellular carcinoma with portal vein tumor thrombus formation. The patient declined any treatment. The tumor in the right lobe of the liver completely regressed after 1 year, and the patient is still undergoing follow-up.ConclusionsWe encountered a hepatocellular carcinoma patient who underwent spontaneous regression, but the exact pathogenesis remains unknown. Understanding the pathogenesis of spontaneous regression of hepatocellular carcinoma has the potential to contribute to the development of an effective treatment for hepatocellular carcinoma.

Purpose: Inflammatory bowel disease (IBD) management is complex and challenging, and therefore, requires a multidisciplinary approach. Whilst pharmacists may play a key role as the first point of contact for patients with initial symptoms or disease relapse, there is scant literature on pharmacists’ knowledge in IBD management. We conducted a survey to explore pharmacists’ knowledge and their perception of pharmacists and other healthcare professionals’ roles in managing patients with IBD.Design and Methodology: An online survey was distributed to pharmacists through professional organisations. The survey included questions about demographic information, concepts related to IBD management and the roles of pharmacists and healthcare professionals in managing patients with IBD.Findings: Fifty two respondents completed the survey. The overall knowledge score for the majority of respondents was categorised as ‘low’ (25-50%) to ‘average’ (51-75%). IBD concept that demonstrated the highest level of accuracy in knowledge scores among pharmacists was the importance of vaccination in IBD (94.2%). Pharmacists who had exposure to patients with IBD demonstrated better knowledge scores compared to those who did not have any exposure to IBD patients in their practice (p = 0.005). Furthermore, General Practitioners (GPs) were perceived as the key care providers to IBD patients, whilst pharmacists considered themselves as important in providing medication related information to patients. Conclusion: This study indicated that pharmacists’ knowledge of IBD and its’ management was suboptimal, but with education and training there are opportunities for pharmacists to play a more active role in managing patients with IBD.

Abstract
Sputtering-made magnetic thin films with metal–ceramic multilayer structures have been reported to achieve excellent magnetic properties and/or new functions for various magnetic materials. However, sputtering-made magnetic films tend to have 10 or fewer layers because the main applications of thin films, such as magnetic sensors, recording heads and recording media, require thin films thinner than 1 μm. This paper reports an Fe–Co/glass multilayer thick-film that has an approximate thickness of 10 μm (above 100 layers). This thick-film was prepared via pulsed laser deposition using several composite targets (two- or three-layer targets) consisting of an Fe–Co alloy (or Fe–Co sheet) and a glass plate. The fabrication of an Fe–Co single-layer film and a glass single-layer film was examined to determine the optimal defocus rate for the composite target. Then, we confirmed that the use of a [glass plate]/[Fe–Co alloy] two-layer target enabled the local formation of a [20 nm thick Fe–Co]/[10 nm thick glass) laminated structure with approximately 130 layers. An Fe–Co/glass multilayer structure was formed by using a three-layer target of a [Fe–Co sheet]/[glass plate]/[metal alloy]. Nonetheless, the results also suggest that large glass droplets should be removed in future work to create homogeneous multilayer thick-films.

Published: September 2022

Abstract
A new high-sensitivity giant magneto-resistance (GMR) sensor system was developed and applied to a magnetic field microscope for which a magneto-impedance (MI) sensor was used as a high-sensitivity magnetic probe. The GMR sensor system achieved a detectivity of 13 pT/√Hz at 100 Hz. The sensing limit and spatial resolution were examined compared with the MI sensor. A 100 Hz AC magnetic field from a patterned Cu line was imaged. The GMR sensor showed better spatial resolution than that of the MI sensor owing to its small sensor unit size. The sensing limit was the same for both the GMR sensor and the MI sensor. This limit is due to ambient magnetic field noise. The GMR sensor could reduce this noise by differential detection using two sensor units. These results suggest that the GMR sensor system has advantages for application to the magnetic field microscopes compared with the MI sensor.

Abstract
Storage phosphor materials can be used to record an incident radiation dose, and they are often used for personal dose monitoring applications and imaging plates (IPs). Conventionally, the storage phosphors for IPs are mainly used in the form of powders and needle crystals while IPs using translucent ceramics have recently attracted much attention. In this paper, we review the recent studies of translucent ceramic storage phosphors for IPs in addition to conventional storage phosphors.
Probing the bandgap and effects of t-BN domains in h-BN neutron detectors
Authors: Tingsuwatit Attasit , Li Jing , Lin Jingyu , Jiang Hongxing 
Published: September 2022

Abstract
Thermal neutron detectors in a lateral scheme were fabricated from a 70 μm thick freestanding B-10 enriched hexagonal BN (h-10BN). Two sets of channel peaks corresponding to the neutron capture by 10B occurring in h-10BN comprising turbostratic domains (t-10BN) have been recognized in the nuclear reaction pulsed height spectrum, from which a bandgap of 5.5 eV was directly deduced for t-10BN. Improved device performance over the prior state-of-the-art implies that the transport properties in the lateral plane of t-BN domains are sufficiently good and their presence in h-BN is not a showstopper for the further advancement of h-BN detector technologies.
Achieving Low-Noise, High-Bandwidth, Nanoscale-Resolution Position Sensing with GMR Sensors
Authors: Joseph Tim John , Kartik V 
Published: September 2022

<p>Nanometer-resolution position sensing is a critical requirement in several precision applications such as Atomic Force Microscopy (AFM), especially over large bandwidths. Giant magnetoresistance-based (GMR) sen?sors have shown great promise for this; however, they exhibit significantly higher 1/f noise even over large band?widths, which limits the achievable SNR. Therefore, the sensing system needs to be designed at the system-level in order to minimize excess intrinsic noise generation and transmission, as well as external noise pickup. This article, both analytically and experimentally, investigates the noise characteristics of the GMR sensor and its readout circuit components, and their effect on SNR. A general process for designing a low-noise high-bandwidth readout circuit, applicable not just to GMR sensors but also to other high?1/f-noise sensors, is presented. A resolution of 2.5 nm over a bandwidth of 100 kHz is demonstrated on an AFM nanopositioner, a ten-fold improvement over previously reported performance and comparable to other state-of?the-art, but more complex, position sensing schemes. The readout scheme is simple to implement using COTS com?ponents and easily extendable to higher bandwidths, unlike other schemes, such as modulation/demodulation, where the requirement for increasingly higher carrier frequencies renders further improvements in bandwidth impractical. </p>

Published: September 2022

Introduction : Rupture of the Radial Collateral Ligament (RCL) of the index metacarpophalangeal (MCP) joint is mostly related to acute local mechanical causes, which severely affect the stability of the MCP joint. Radial collateral ligament (RCL) injuries account for 10-40% of collateral ligament injuries of the thumb metacarpophalangeal joint.ere, we present an extremely rare case of chronic RCL injury.
Patient Concern : Pain in the thumb of the right hand accompanied by weakness when trying to grasp something. Complaints are not accompanied by swelling. Patient said 2 years ago had an accident. Thumb at right hand is said to be swollen and shifting.
Diagnosis : Based on the combination of physical examination, X-ray, and ultrasonic and magnetic resonance imaging, the patient was diagnosed with Radial Collateral Ligament rupture. Eventually, intra-operative findings confirmed the diagnosis.
Intervention : Patient was underwent ligament reconstruction using a Palmaris Longus tendon graft.
Conclusion : Favorable results suggest that the free tendon graft using Palmaris Longus is a suitable, safe, and technically feasible procedure for the operative treatment of chronic instability of the thumb metacarpophalangeal joint after radial hyperadduction trauma and complete rupture or deinsertion of the radial collateral ligament.

El trabajo investigativo tiene como objetivo explicar el abuso de la prisión preventiva durante la emergencia sanitaria por COVID-19 en el hacinamiento del penal El Milagro -Trujillo, 2021. Para ello se ha empleado el enfoque cualitativo el cual recoge y analiza datos no numéricos para comprender conceptos, opiniones o experiencias de los profesionales entrevistados que revelan emociones o comportamientos necesarios para la elaboración del presente documento. Además, el diseño fenomenológico. Para el procesamiento de la información obtenida de las respuestas de nuestros entrevistados ha sido sometida a un riguroso análisis con el fin de someterlas a discusión y debate.
Las conclusiones más importantes fueron que se ha reconocido la excarcelación de los presos preventivos durante la crisis sanitaria por COVID-19 debido al empleo del D.Leg. 1513, en consecuencia, una leve disminución de reos `preventivos en el 2020. Sin embargo, el 2021 el número de internos preventivos aumentó, tan es así que a la fecha representan casi el 35 por ciento de la población total. Lo que revela que el D. Leg. que tiene por finalidad la excarcelación de los reclusos para evitar el contagio de la COVID-19 ha sido coyuntural, no obstante, no se ha solucionado el problema de fondo: el hacinamiento penitenciario.
