Published: October 2021

MRI is a complex, rapidly evolving modality which has assumed an increasingly important role in the diagnosis of Sellar region tumors. It is now the preferred modality for the definitive evaluation and follow-up of the most sellar region tumors. Using different pulse sequence small lesion can be detected even without contrast. Gd-DTPA provides valuable information in MR imaging sellar region tumors, particularly in pre-operative evaluation. This study was conducted to elucidate the accuracy of MRI in pre-operative evaluation of sellar region tumors and its validity by determining sensitivity, specificity, positive and negative predictive value with histopathological correlation. This cross sectional observational study was carried out in the department of radiology and imaging in collaboration with department of Neurosurgery, Dhaka Medical college Hospital, Dhaka during the period of January 2008 to April 2009. MRI of brain was done on 42 patients referred for evaluation of sellar region tumors. The following result and observation were obtained. The age range of the patient was 20 to 80 years. The mean age (HSE) was 34.31(+2.80). Maximum patients were in age group 20-30 years and male-female ratio was 1.8:1. Most sellar region tumor located in the intrasellar with suprasellar extension. Out of 42 patients 37 (88%) patients were truly diagnosed by MRI as sellar region tumors. The sensitivity of MRI to diagnosed macro adenoma was 81.25%, specificity 80.76%, positive predictive value 72.2%, negative predictive value 87.5%, accuracy 80.95%. This study finds that MRI is a valid imaging modality in the diagnosis of pituitary adenoma and sellar region tumor.

During the gestational period, fetal biometrics are assessed through ultrasonography to observe the growth of the fetus. This study observed the corresponding of gestational age those were measured by two of the fetal diameters; gestational age were calculated from history of last menstrual period (LMP), in the last two trimesters. This descriptive type of observational study was carried out in the Department of Radiology and Imaging of Dhaka Medical College and Hospital, during the period of July, 2004 to June, 2005. Here 291 single-ton, non-complicated pregnant women of LMP were selected purposively from valid record. Bi-parietal diameter (BPD) and femoral length (FL) estimated through ultrasonography. These two parameters compared with the gestational age in second and third trimester. The study found that, before 36th week, the BPD based gestational age varied 2 to 3 days from LMP based gestational age and after that, the variation was 1 to 4 weeks. In case of FL, the ultrasonic measurement found to be 2 to 4 days backward in the second trimester and 2 to 3 days advance in the last trimester in contrast to the LMP based gestational age. In the second trimester, it has been found that, BPD has been the superior predictor of the gestational age than the FL with the correlation coefficient of 0.999 in case of BPD and 0.998 in case of FL when correlated with LMP based gestational age. Although, in third trimester, FL versus BPD predicted the gestational age with a correlation coefficient of 0.998 versus 0.978 respectively, when correlated with gestational age based on the history of LMP. This study has observed that, later in pregnancy, FL has the better predictability over BPD to determine the gestational age.

Published: October 2021

Dentre as diversas cultivares de tomate, a demanda e a oferta pelo mini tomate têm aumentado nos últimos anos, pois além de ser muito saboroso, é bastante atrativo, sendo muito utilizado na ornamentação de pratos e no preparo de saladas. A utilização de mini tomates como adorno, aperitivo e na confecção de pratos diversos é uma forma de consumo dessa hortaliça, que é bastante consumida em restaurantes por ser considerado uma hortaliça exótica de tamanho pequeno e delicado. Neste contexto, o objetivo do trabalho foi avaliar a vida de prateleira do tomate Sweet Grape produzido em hidroponia com água residuária submetido a diferentes condições de armazenamento. O delineamento experimental foi inteiramente casualizado em esquema fatorial 4 x 2, totalizando oito tratamentos com seis repetições. Os tratamentos foram: quatro dias (0, 7, 13 e 15) e duas temperaturas (refrigerada e ambiente). O tomate foi cultivado em sistema hidropônico com água residuária. Os frutos foram colhidos e acomodados em bandejas poliestireno expandido revestidas com papel filme. Para a análise sensorial utilizou-se Método Afetivo Quantitativo, em que 30 julgadores não treinados, consumidores de tomate, avaliaram os seguintes atributos de qualidade do produto: aparência externa, cor, aparência interna, textura (firmeza) e aroma. No teste de aceitabilidade empregou-se escala hedônica de nove pontos (ancorada em seus extremos por “gostei muitíssimo” e “desgostei muitíssimo”). Os dados obtidos foram submetidos à análise de variância pelo teste F e as comparações entre as médias dos tratamentos foram realizadas pelo teste de Tukey a 5%. Para os resultados obtidos os parâmetros aparência externa e aroma demonstraram diferença para os dias 13 e 15. Já nos parâmetros de cor e textura os tratamentos não demonstraram diferença estatística. A aparência interna demonstrou diferença apenas na temperatura ambiente para os diferentes dias. Desta forma, pode-se concluir que a qualidade do fruto, refletida na análise sensorial para vida de prateleira se mantêm mesmo em diferentes condições de armazenamento e período de estocagem (dias).

A solução para o tratamento de resíduos como o lodo de curtume pode ser a vermicompostagem. Manter o potencial nutritivo, para aplicação agrícola como no cultivo de tomate, e também utilizar água residuária doméstica, pode amenizar a contaminação de meio ambiente. Neste contexto, o objetivo do trabalho foi avaliar a produção de tomate Santa Cruz Kada (paulista) irrigado com água residuária doméstica e adubado com vermicomposto de lodo de curtume. O delineamento experimental foi inteiramente casualizado em esquema fatorial 6 x 2, totalizando doze tratamentos com cinco repetições. Os tratamentos foram: quatro vermicompostos de lodo de curtume (25% de Lodo de curtume+Esterco bovino – T1; 25% de Lodo de curtume+Casca de arroz – T2; 50% de Lodo de curtume+Esterco bovino – T3 e 50% de Lodo de curtume+Cinza de cana – T4), adubação convencional (T5) e testemunha (sem adubação – T6) e dois tipos de água de irrigação (água de abastecimento e água residuária). O tomate foi transplantado e conduzido em vasos com volume útil de seis litros, tutorado com estacas de bambu e mantidos duas hastes por planta em cada vaso. Os vermicompostos e o solo utilizados foram caracterizados física e quimicamente, assim como a água residuária doméstica, que foi analisada qualitativamente. Nos frutos de tomate foram realizadas análises de: peso, medidas de diâmetros longitudinal e transversal; pH e oBrix. Os dados obtidos foram submetidos à análise de variância pelo teste F e as comparações entre as médias dos tratamentos foram realizadas pelo teste de Tukey a 5%. Para os resultados obtidos o T2 apresentou maior valor de peso dos frutos assim como de produção (6,68 kg) e diâmetro longitudinal. Para os valores de pH dos frutos de tomate se destaca o T4 com valor de 4,40, o que não difere dos demais tratamentos, com exceção do T1. Para os diferentes tipos de água (A1 e A2) observa-se que os T3 e T5 possuem maiores valores de pH e oBrix. Conclui-se que a produção de tomate pode ser adotada como destinação final da água residuária e do lodo de curtume, resultado em produção satisfatória, principalmente com doses menores de lodo (25%).

The combination of increased fat mass with a decrease in muscle mass and strength in the elderly has been termed sarcopenic obesity (SO). In addition, augmented levels of inflammatory markers have been reported in subjects with SO. Two hundred-sixteen obese elderly women were included in this cross-sectional study. They underwent body composition analysis by DEXA to define the presence of SO. Volunteers were divided into two groups: SO (n= 83; 66.7 ± 5.6 years) and non-SO (n= 133; 67.6 ± 4.9 years) for the comparison of inflammatory cytokines. There were no significant differences between SO and non-SO groups in the blood concentrations of the inflammatory markers analyzed, e.g. interleukin-6 (0.82 ± 0.20 vs 0.83 ± 0.19 pg/ml; p=0.64), C-reactive protein (2.70 ± 1.55 vs 2.82 ± 1.66 pg/ml; p=0.71), tumor necrosis factor alpha (0.71 ± 0.08 vs 0.70 ± 0.08 pg/ml; p=0.42) and interferon-gamma (0.75 ± 0.14 vs 0.74 ± 0.08 pg/ml; p=0.47), respectively. Thus, in the studied population, inflammatory markers are not exacerbated by SO when compared to obesity without sarcopenia.
Learning the Use of Artificial Intelligence in Heterogeneous Catalysis
Authors: Bokhimi Xim 
Published: October 2021

We describe the use of artificial intelligence techniques in heterogeneous catalysis. This description is intended to give readers some clues for the use of these techniques in their research or industrial processes related to hydrodesulfurization. Since the description corresponds to supervised learning, first of all, we give a brief introduction to this type of learning, emphasizing the variables X and Y that define it. For each description, there is a particular emphasis on highlighting these variables. This emphasis will help define them when one works on a new application. The descriptions that we present relate to the construction of learning machines that infer adsorption energies, surface areas, adsorption isotherms of nanoporous materials, novel catalysts, and the sulfur content after hydrodesulfurization. These learning machines can predict adsorption energies with mean absolute errors of 0.15 eV for a diverse chemical space. They predict more precise surface areas of porous materials than the BET technique and can calculate their isotherms much faster than the Monte Carlo method. These machines can also predict new catalysts by learning from the catalytic behavior of materials generated through atomic substitutions. When the machines learn from the variables associated with a hydrodesulfurization process, they can predict the sulfur content in the final product.

Traditional radio frequency filters cannot meet the demands of miniaturization, high frequency operation, integration, and broadband capacity in new-generation communication system owing to their larger volumes. A thin film bulk acoustic resonator (FBAR) is therefore suggested as an optimum solution because of its small volume and a good performance. In this study, the COMSOL multiphysics software was used to build 2 D and 3 D finite element models to analyze the harmonic characteristics of the FBAR. Based on the optimized structural parameters, the FBAR was fabricated with series resonant frequency, parallel resonant frequency, and effective coupling coefficient values of 3.705, and 3.82 GHz, and 7.4%, respectively. Compared with the simulated FBAR results, the effective coupling coefficient of the fabricated FBAR declined by only 0.1%, almost achieving the desired performance.

Published: October 2021

Objectives: Endothelial dysfunction (ED) has been linked to the pathogenesis of cerebral small vessel disease (SVD). We aimed to assess ED and cerebrovascular reactivity (CVR) in the patients with a diverse manifestation of SVD, with similar and extensive white matter lesions (WMLs, modified Fazekas scale grade ≥2), compared with a control group (CG) without the MRI markers of SVD, matched for age, gender, hypertension, diabetes, and to evaluate the change of CVR following 24 months.Methods: We repeatedly measured the vasomotor reactivity reserve (VMRr) and breath-holding index (BHI) of the middle cerebral artery (MCA) by the transcranial Doppler ultrasound (TCD) techniques in 60 subjects above 60 years with a history of lacunar stroke (LS), vascular dementia (VaD), or parkinsonism (VaP) (20 in each group), and in 20 individuals from a CG.Results: The mean age, frequency of the main vascular risk factors, and sex distribution were similar in the patients with the SVD groups and a CG. The VMRr and the BHI were more severely impaired at baseline (respectively, 56.7 ± 18% and 0.82 ± 0.39) and at follow-up (respectively, 52.3 ± 16.7% and 0.71 ± 0.38) in the patients with SVD regardless of the clinical manifestations (ANOVA, p &gt; 0.1) than in the CG (respectively, baseline VMRr 77.2 ± 15.6%, BHI 1.15 ± 0.47, p &lt; 0.001; follow-up VMRr 74.3 ± 17.6%, BHI 1.11 ± 0.4, p &lt; 0.001). All the assessed CVR measures (VMRr and BHI) significantly decreased over time in the subjects with SVD (Wilcoxon's signed-rank test p = 0.01), but this was not observed in the CG (p &gt; 0.1) and the decrease of CVR measures was not related to the SVD radiological progression (p &gt; 0.1).Conclusions: This study provided evidence that the change in CVR measures is detectable over a 24-month period in patients with different clinical manifestations of SVD. Compared with the patients in CG with similar atherothrombotic risk factors, all the CVR measures (BMRr and BHI) significantly declined over time in the subjects with SVD. The reduction in CVR was not related to the SVD radiological progression.

Published: October 2021

Background: Previous studies have reported that olfactory identification deficits may be the earliest clinical features of Alzheimer's disease (AD). However, the association between odor identification and hippocampal atrophy remains unclear.Objective: This meta-analysis quantified the correlation between odor identification test scores and hippocampal volume in AD.Method: A search of the PUBMED, EMBASE, and WEB OF SCIENCE databases was conducted from January 2003 to June 2020 on studies with reported correlation coefficients between olfactory identification score and hippocampal volume in patients with amnestic AD or mild cognitive impairment (MCI). The quality of the studies was assessed using the Newcastle-Ottawa quality assessment scale (NOS). Pooled r-values were combined and computed in R studio.Results: Seven of 627 original studies on AD/MCI using an olfactory identification test (n = 902) were included. A positive correlation was found between hippocampal volume and olfactory test scores (r = 0.3392, 95% CI: 0.2335–0.4370). Moderator analysis showed that AD and MCI patients were more profoundly correlated than normal controls (AD: r = 0.3959, 95% CI: 0.2605–0.5160; MCI: r = 0.3691, 95% CI: 0.1841–0.5288; NC: r = 0.1305, 95% CI: −0.0447–0.2980). Age difference and patient type were the main sources of heterogeneity in this analysis.Conclusion: The correlation appears to be more predominant in the cognitive disorder group (including MCI and AD) than in the non-cognitive disorder group. Age is an independent factor that affects the severity of the correlation during disease progression. The mildness of the correlation suggests that olfactory tests may be more accurate when combined with other non-invasive examinations for early detection.Systematic Review Registration:https://inplasy.com/, identifier INPLASY202140088.
