Authors: Paul Mekhla , Rastogi Amit , Chatterje Arindam , Agarwal Aarti , Mishra Prabhaker , Khan Ajmal 
Published: January 2021

Context:
Rigid bronchoscopy (RB) procedures require continuous vigilance and monitoring. Such procedures warrant proper ventilation strategy and titration of potent short-acting anesthetics.

Aims:
To compare propofol with the propofol-dexmedetomidine in conjunction with topical airway anesthesia in two groups during spontaneous assisted ventilation on peri-procedural hemodynamic stability.

Settings and Design:
This prospective, randomized, double-blinded study was done on 40 patients who were randomized in two groups, 20 patients in each group; PS (Propofol+ Normal saline) and PD (Propofol+ Dexmedetomidine) group. All patients in both groups were induced with 1% IV propofol (1–3 mg/kg), IV midazolam (0.05 mg/kg), and IV fentanyl (2 μ/kg). PS group received propofol infusion for maintenance along with saline infusion 10 min before induction, whereas PD group also received propofol infusion for maintenance along with Injection dexmedetomidine infusion 10 min before induction. Outcome measured were heart rate (HR), mean blood pressure (MBP), oxygen saturation (SpO2), and post-procedure awakening using Modified Observer's Assessment of Alertness/Sedation (MOAAS) scale and complications.

Results:
In both the groups, MBP decreased significantly from baseline, however, when MBP were compared at the same time points between the groups there were no significant differences. In PD group, HR remained significantly lower when compared with baseline and at 6, 12, 18, and 24 min time points when compared with PS group. Number of patients who developed hypotension requiring vasoactive drugs, their mean dose and duration of hypotension were more in PD group, and they awoke with significant delay.

Conclusions:
Propofol is better than combination of propofol and dexmedetomidine when given in adjunct with topical airway anesthesia for RB in view of early awakening, lesser duration of intra-procedural hypotension, and lesser requirement of vasoactive agents.

Authors: Dayal Seema , Krishna Mani , Kannaujia Sanjay Kumar , Singh Seema 
Published: January 2021

Background:
Breast lesions extend from benign to malignant ones. The National Cancer Institute recommended categories for the diagnosis of breast cytology. There are some lesions in the breast which are called intermediate or gray lesions. It includes C3 (atypical, probably benign) and C4 (suspicious, favor malignant) which needs to be evaluated.

Materials and Methods:
This study was conducted in the Department of Pathology, Uttar Pradesh University of Medical Sciences, Saifai, Etawah (Uttar Pradesh). Fine-needle aspiration cytopathology (FNAC) was the diagnostic tool. The present study was undertaken to determine the gray lesions of the breast and its correlation with histopathology and other associated parameters. Immunohistochemistry was applied where ever necessary. One hundred and fifty one cases of gray lesions of the breast were included.

Results:
C3 was seen in 85 (56.29%) and C4 in 66 (43.70%) patients. The maximum number of patients was of 31–40, (33.77%) years age group, the youngest patient was 12-year-old female, whereas the oldest was 86 years male. Histopathology evaluation confirmed malignancy in 35 (23.17%) cases, and infiltrating ductal carcinoma was the frequent malignancy (24 [68.5%]). Sensitivity, specificity, positive predictive value, and negative predictive value of C4 category for the diagnosis of malignancy were, respectively, 81.48%, 50%, 68.7%, and 64.2%.

Conclusion:
FNAC is an excellent diagnostic tool. It has some limitations, especially with the gray lesions, which may lead to miss interpretation in diagnosis, so a scope of mistake to the cytopathologist is always there. These lesions need to be evaluated because of the risk of malignancy. However, gray lesions can be reduced by cytology followed by histopathology examination along with ancillary radiological investigations such as mammography and ultrasonography.

Published: January 2021

La pulpotomía es un tratamiento endodóncico frecuentemente realizado en niños. A pesar de que se trata de un procedimiento seguro, se han reportado efectos secundarios. Caso clínico: Un niño de 10 años de edad llegó para revisión dental. Los resultados de los rayos X mostraron una lesión radiolúcida por encima del segundo molar primario superior izquierdo, relacionada con el diente permanente. La extracción de los primeros y segundos molares primarios se realizó bajo anestesia local. La lesión quística se eliminó quirúrgicamente, y el análisis histopatológico mostró un quiste dentígero inflamatorio. Una cavidad casomarsupialización fue creada para permitir la erupción de los premolares. Después de un año de seguimiento, el hueso se había regenerado totalmente y los premolares habían erupcionado completamente. Conclusión: Este caso resalta la necesidad de una supervisión regular de los dientes pulpotomizados, incluso si están asintomáticos, además de la fase de erupción de los dientes permanentes y primarios. La marsupialización del quiste dentígero permitió el tratamiento eficaz y la preservación del premolar involucrado.

Published: January 2021

Uno de los factores que influye en los accidentes ocupacionales es la percepción. Por ello, fue necesario analizar la percepción de los riesgos laborales que tienen las personas en el ámbito profesional, con la finalidad de reducir el índice de accidentabilidad que surgen en los puestos de trabajo al momento que los colaboradores ejecutan las actividades funcionales. Para llevar a cabo este estudio, se aplicó un enfoque cuantitativo, un alcance descriptivo, con un diseño de investigación no experimental-transeccional. Se utilizó el método “Escala de Percepción del Riesgo” de García, Castaño, Oliver y Ramírez (2009). Para analizar la percepción, en primera momento se examinó la exposición de los riesgos laborales, mediante tres dimensiones: grado de existencia del riesgo, efectos para la salud y control de los efectos negativos.
En esta investigación se analizó la percepción de los riesgos del trabajo desde dos criterios: Percepción de riesgo alta y percepción de riesgo baja en los trabajadores de la Facultad de Ciencias Administrativas y Económicas de la institución educativa superior Universidad Técnica Luis Vargas Torres, la cual, se encuentra situada en Esmeraldas-Ecuador. Se lo abordó analizando tres estrados: docentes, administrativos y auxiliares de limpieza. En los hallazgos obtenidos de este estudio se evidencia que, la percepción del riesgo ergonómico es alta en los docentes, mientras que, la percepción es baja en el personal: administrativo y auxiliar de limpieza. En cuanto al riesgo químico, la percepción es baja en el personal auxiliar de limpieza.

A two-stage blending approach for merging multiple satellite precipitation estimates and rain gauge observations: an experiment in the northeastern Tibetan Plateau

Published: January 2021

Abstract. Substantial biases exist in satellite precipitation estimates (SPEs) over complex terrain regions, and it has always been a challenge to quantify and correct such biases. The combination of multiple SPEs and rain gauge observations would be beneficial to improve the gridded precipitation estimates. In this study, a two-stage blending (TSB) approach is proposed, which firstly reduces the systematic errors of the original SPEs based on a Bayesian correction model and then merges the bias-corrected SPEs with a Bayesian weighting model. In the first stage, the gauge-based observations are assumed to be a generalized regression function of the SPEs and terrain feature. In the second stage, the relative weights of the bias-corrected SPEs are calculated based on the associated performances with ground references. The proposed TSB method has the ability to extract benefits from the bias-corrected SPEs in terms of higher performance and mitigate negative impacts from the ones with lower quality. In addition, Bayesian analysis is applied in the two phases by specifying the prior distributions on model parameters, which enables the posterior ensembles associated with their predictive uncertainties to be produced. The performance of the proposed TSB method is evaluated with independent validation data in the warm season of 2010–2014 in the northeastern Tibetan Plateau. Results show that the blended SPE is greatly improved compared to the original SPEs, even in heavy rainfall events. This study can be expanded as a data fusion framework in the development of high-quality precipitation products in any region of interest.

Authors: Jung Jochen , Münch Annika , Herbst‐Irmer Regine , Stalke Dietmar 
Published: January 2021

AbstractThe valence isoelectronic imido analog H2S(NtBu)4(1) of sulfuric acid H2SO4was synthesized, isolated, and characterized by NMR spectroscopy and high‐resolution X‐ray charge density analysis. The latter reveals strongly polarized Sδ+−Nδ−bonds with virtually no double bond character. The easy‐to‐polarize S−N bonds are an advantageous and versatile feature of sulfur nitrogen ligands, which enables them to adapt to different electron requirements of various metal cations.
The topographic and systematic anatomy of the alpaca stomach

Published: January 2021

AbstractThe gastric anatomy of the alpaca (Vicugna pacos) is adapted to the physiological process of ruminating and the degradation of plant cell wall contents to a great extent. Most alpaca husbandries consist of only few animals and with the still increasing number of alpacas worldwide the number of persons who are responsible for these animals is increasing as well. Despite this, little research has been done with regard to the clinical anatomy of the stomach of alpacas. Six animals were used for dissection. The vascular system of two alpacas was injected with latex milk to illustrate the course of the blood supply to the viscera. One stomach was used to prepare formalin‐fixed preparations. The stomach consisted of three compartments (C1–C3) and showed two sacculated areas in C1 and another comb‐like system in C2. The compartments were lined by a smooth mucosa. Only the deep cells of C2 were lined by a papillated mucosa. The main blood supply was provided by the coeliac artery which was divided into the hepatic artery and the left gastric artery, supplying abdominal organs like liver, spleen, pancreas, and the initial part of the duodenum. Literature research on the llama stomach showed that the alpaca stomachs that were used resembled each other to a very large degree. The specific design of the stomach together with its related functions and physiological processes confirm that the evolution of Tylopoda and Ruminantia took place in parallel and not in homology.

AbstractWe present reddening, photometric metallicity, age, and distance estimates for the Frolov 1 and NGC 7510 open clusters based on charge‐coupled device (CCD)UBVphotometric andGaiadata. Photometric observations were collected using the 1‐m telescope of the TÜBİTAK National Observatory.Gaiadata release 2 (DR2) proper motion data in the direction of two groupings were used to identify cluster membership. We determined mean proper motion values of (μαcosδ,μδ) = (− 3.02 ± 0.10, − 1.75 ± 0.08) and (−3.66 ± 0.07, −2.17 ± 0.06) mas year−1for Frolov 1 and NGC 7510, respectively. We used two‐color diagrams to obtainE(B − V) color excesses for Frolov 1 and NGC 7510 of 0.65 ± 0.06 and 1.05 ± 0.05 mag, respectively. We derived the photometric metallicity of Frolov 1 as [Fe/H] = 0.03 ± 0.03 dex and adopted a solar metallicity for NGC 7510. Based on these reddening and metallicities, we determined the distance moduli and ages of the clusters by fitting stellar tracks and isochrones with the PAdova and TRieste Stellar Evolution Code (PARSEC) isochrones to the cluster color–magnitude diagrams. Isochrone‐fitting distances for Frolov 1 and NGC 7510 are 2, 864 ± 254 and 2, 818 ± 247 pc, respectively, which correspond to the ages 35 ± 10 Myr and 18 ± 6 Myr. We also calculated meanGaiadistances and compared them with those given in the literature and in this study, concluding that our results are in good agreement with previous work. Finally, we calculated the mass function slopes and found them to beX = −1.21 ± 0.18 for Frolov 1 andX = −1.42 ± 0.27 for NGC 7510.
Magnetic field effect on early universe events
Authors: Piccinelli Bocchi Gabriella 
Published: January 2021

AbstractAn outlook of different aspects of the incidence of magnetic fields on early universe events is presented. The events we will focus on include inflation and the electroweak phase transition. The guideline of the study is mainly the effect of the magnetic field on the effective potential of phase transitions and the decay process of the field leading the phase transition. We will consider both weak and strong magnetic field approximations, since this issue seems to make some important differences in the results. Besides presenting the results of our working group, we will also discuss other works that can be found in the literature.
Guar gum based hydrogel as controlled micronutrient delivery system: Mechanism and kinetics of boron release for agricultural applications

Published: January 2021

AbstractA boron loaded super‐absorbent hydrogel (BLSAH) was developed through in situ incorporation of boron (B) in a guar gum‐based hydrogel and characterized with FTIR, thermo‐gravimetric analysis (TGA), scanning electron microscopy (SEM), and swelling studies, showing maximum absorption up to 356 g/g. The release pattern of B from the BLSAH and its kinetics was studied in water as well as soil. The B release pattern of the BLSAH was also compared with the commercial B fertilizer, boronated single super phosphate (bSSP). The BLSAH, following the Fickian mechanism, released 38% B, as compared with 51% of the bSSP, during the incubation period of 30 days in soil. The half‐life period for the BLSAH (96.25 days) in soil was almost triple that of the bSSP's half‐life (33.32 days), which is indicative of the slow and controlled release of B from the BLSAH. Thus, owing to its sustained nutrient release ability, the synthesized BLSAH exhibited wide potential for applications in agriculture sector.
