Authors: Mutassif Syed , Prabhat Archana
Published: November 2022

Breakfast, an important meal of day's menu refills the supply of glucose for metabolism and provides other essential nutrients to keep the energy levels boosted all throughout the day. School children are more prone to skip their breakfast and are vulnerable for their nutritional status and cognitive functioning. In India, 50% of the children population are regular breakfast skippers. To assess the effect of skipping breakfast and its effect on Intelligent Quotient (IQ) level, understanding reasons for skipping breakfast and to study their dietary intake and impart nutrition education. A total of 80 Subjects were selected from both of government and private schools. Data was collected using pre-structured questionnaire and anthropometric measurements along with IQ test and are recorded. Data was entered and analysed using SPSS 16. Reason for skipping breakfast was lack of time among private school children and in government school it was a family practice. Skipping breakfast had resulted in low IQ level and poor academic performance in both the school groups. Breakfast skippers in private school were more prone to overweight but in government school skippers were more prone to underweight. Skipping breakfast has a negative impact on nutritional status of school children effecting their cognitive functioning.

Acacia nilotica is a potential source of protein, fibre and natural antioxidants. Also, the protein fractions from acacia seeds possess high functional properties that could be advantageous in food formulation. However, acacia pods possess a bitterness that hinders its utilization for value addition. We have developed composite flours in combination with raw banana flour. Two types of composite flours were developed substituting 30 and 50 per cent of banana flour with acacia flour. Acacia flour exhibited significantly higher (pâ‰¤0.05) water and oil absorption capacity, swelling power as well as sedimentation value compared to banana flour. Also, it was a significantly richer (pâ‰¤0.05) source of protein (12.95%), crude fibre (12.66 %) as well as DPPH activity (59.60 %). The two composite flours, respectively exhibited 0.86 and 1.35 g/g water absorption capacity; 0.44 and 0.76 g/g oil absorption capacity; 4.14 and 4.06 g/g swelling power; 14.22 and 15.36 ml/g sedimentation value. The crude protein content in respective composite flours was 9.36 and 11.86 % with 4.96 and 5.50 % crude fibre, 40.60 and 40.69 % dietary fibre, 27.05 and 34.06 % DPPH activity.

Science and technology in today era is exploring the possibilities of keeping the phrase "Let food be thy Medicine”. Compared to staple cereals rice and wheat, millets are termed as 'Nutri cereals' that have high proportion of non-starchy polysaccharides and dietary fiber and has low glycemic index. Pearl millet is a drought tolerant crop cultivated in most parts of Africa and Asia, has high level of calcium, iron, zinc, lipids and good quality protein. Noodles are one of the most popular foods in the world; it ranks second after bread in the global consumption. Generally noodles are prepared using refined wheat flour and studies have shown the enrichment of noodles with wheat flour and millets, green leafy vegetables and others vegetables etc. In this study an attempt was taken to prepare homemade noodles by replacing the refined wheat flour totally with wheat flour and pearl millet flour. Pearl millet (Pennisetum glaucum) is processed into flour and substituted with wheat flour in five different proportions 40:60, 50:50, 60:40, 70:30 and 80:20. The formulated blends were used in the production of noodles and their cooking characteristics such as water absorption, swelling index and cooking loss were found. And the formulated noodles were further subjected to sensory evaluation by the panel of 30 members. The result showed that the noodles prepared with blend of wheat flour (60 per cent) and pearl millet flour (40 per cent) is found to be the most commonly accepted blend in both dry and cooked noodles. Hence pearl millet flour noodles will be a promising substitute when compared with commercial noodles in quality, taste and flavor.

Cereals/millets and pulses are an important parts of healthy and balanced diet and hence helps in bridging the gap of protein hunger malnutrition and micronutrient deficiencies. To increase the shelf life of perishable and non-perishable food items, drying is one of the primary and oldest processing techniques that the food grains are subjected to. The convection oven drying method is one of the commonly used methods for the estimation of moisture in marketing enterprises and industries but as the time consumption is quite higher in this process a replacement but quick and dependable technique is essential. One variety rice (Luit variety), one variety of millets and one variety of pulses (samples) were used for the study. Experiments with temperature varying from 30-60 °C and varied time intervals (15 minutes) were conducted in a microwave oven and convection oven using the samples. The main parameters used for the study were temperature and time which was recorded after a time interval of 15 minutes1. The results stated that the process of drying takes place at a falling rate period i.e. with the rise in temperature the moisture content decreases. At a very long process the drying rate, the curve slop becomes less sharp and slowly tends to be horizontal at longer period of time. The values are calculated when the moisture content of the samples becomes constant. Drying food grains for a longer time period have adverse effect in the nature of the samples along with it can result in income loss of marketing industries.Salient findings from the study can be that the alternative means for the convection oven drying can be microwave oven drying as it can be a favorable method for the estimation of moisture content in food grains.

Se realizaron tres pruebas (P1, P2, P3) con diferentes concentraciones de peróxido de hidrógeno (H2O2) y sulfato ferroso (FeSO4) (los cuales forman el reactivo Fenton) para determinar cuál de las pruebas generaba una mayor reducción de los parámetros físico-químicos: sólidos totales (ST), conductividad eléctrica (CE), turbidez y demanda química de oxígeno (DQO) presentes en las aguas residuales. Luego de ello, se escogió la prueba 2 (P2) debido a que produjo una mayor reducción de los mencionados parámetros. Se realizó una repetición de la P2 para determinar la dosificación idónea para ser utilizada en la fábrica textil, lo que permitió obtener que la dosificación idónea era de 0.92 mL de H2O2 y 400 mg de Fe2+, debido a que se obtuvieron valores de reducción de los parámetros del 68.8%, 99.97%, 96.8% y 82.5% para los ST, CE, turbidez y DQO respectivamente. Se concluyó que el reactivo Fenton es beneficioso para la fábrica textil, puesto que genera una reducción de los parámetros y permite que no superen los Valores Máximos Admisibles (VMA), los cuales permiten que los efluentes vertidos al sistema de alcantarillado no generen ningún tipo de impacto en los ecosistemas acuáticos.

Fever is the hallmark of efficient acute inflammatory response, which may be disrupted in chronic inflammatory conditions. “The Continuum Theory” proposes that the return of acute inflammatory states with high fever herald improvement in chronic diseases during treatment. Our objective was to investigate if a correlation exists between chronic inflammation and efficient acute inflammation. In a case control study, the reports of patients diagnosed with chronic inflammatory conditions with at least 6 months of follow up under homeopathic treatment were retrospectively sampled from homeopathic medical practitioners from Greece, India, Romania, and Russia. 20 patients who improved under homeopathic treatment and 20 age matched controls of those who did not improve were selected. The occurrence of common acute infectious diseases with fever during the follow up period was investigated. The Odds Ratio of improving with respect to development of acute infectious diseases was calculated and graphs were plotted to study the pattern in each case. The average age of the cases and controls was 28.4 and 27.9 years respectively. 18/20 cases and 4/20 controls developed common infectious diseases with fever respectively. Odds Ratio of improving with respect to development of acute infectious diseases was 36 (95%, CI: 5.7973 to 223.5513), z statistic: 3.846 (p = 0.0001). In this case control study, appearance of common acute infectious diseases with fever was strongly associated with improvement in the chronic inflammatory conditions.

Fluvial carbon fluxes (FCFs) have attracted growing attention in recent decades due to its indispensable role in the global carbon cycle and budgets. To identify the major characteristics and evolutionary trends of FCFs related research, this study adopts a bibliometric method to analyze the publications retrieved from the database of Web of Science during 1997–2022. The information related to countries, institutes, authors, journals, collaboration, keywords and research trends is presented. Findings show that the publication number of FCFs related research had significant increase in the past 25 years. Science of the Total Environment, Biogeosciences and Journal of Hydrology were the most influential journals in this field. China, the USA and France ranked the top 3 countries in publication number. Previous studies concentrated on the source and fate, influential factors, process and estimation model of FCFs. The research trend of FCFs may focus on FCFs of Arctic rivers and their biogeochemical processes, the impact of human activities on FCFs, new techniques developed for FCFs research, and carbon exchange estimates across water-air interface. This study provides researchers with a better understanding of the current state of FCFs and serves as an effective reference for future studies.

Published: November 2022

Background
To establish a nomogram integrating radiomics features based on ultrasound images and clinical parameters for predicting the prognosis of patients with endometrial cancer (EC).
Materials and methods
175 eligible patients with ECs were enrolled in our study between January 2011 and April 2018, which were divided into a training cohort (n = 122) and a validation cohort (n = 53). Least absolute shrinkage and selection operator (LASSO) regression was applied for selection of key features and a radiomics score was calculated. According to the rad-score, patients were stratified into high-risk and low-risk groups. The univariate and multivariable COX regression analysis was used to select independent clinical parameters for disease free survival (DFS). The combined model based on radiomics features and clinical parameters was finally established, and the performance was quantified with respect to discrimination and calibration.
Results
9 features were selected from 1130 features using LASSO regression in the training cohort, and yielded the area under the curve (AUC) of 0.823 and 0.792 to predict DFS in training and validation cohorts respectively. Patients with higher rad-score were significantly associated with worse DFS. The combined nomogram, which was composed of clinically significant variables and radiomics features, showed a calibration and favorable performance for DFS prediction (AUC 0.893 and 0.885 in the training and validation cohort, respectively).
Conclusion
The combined nomogram could be used as a tool in predicting DFS and may assist individualized decision making and clinical treatment.

Objective: The aim was to evaluate the associations of short-term exposure to main constituents of PM2.5 with lung function and impulse oscillometry system in China.
Methods: A four-year observational cohort study based on hospital outpatient visits between January 1, 2016 to December 31, 2019 was conducted in northern China. A total of 2151 outpatients were randomly selected from four hospitals in Beijing (who were divided into patients with acute exacerbation of COPD (AECOPD) (1348 cases) and without AECOPD (803 cases)). Multivariable linear regression models were used to obtain differences of lung function index and impulse oscillometry system (IOS) parameters associated with PM2.5, adjusting for sex, smoking history,education level, age, body mass index (BMI), mean temperature, and relative humidity.
Results: Significant associations were found between lung function and IOS with PM2.5 in AECOPD patients in Beijing, China. An increase of 10 ug/m3 in PM2.5 was associated with a decline of 2.08% (95% CI: −3.05 to −1.10) in FEV1/pred, a decline of 0.19 L/s (95% CI: −0.26 to −0.04) in PEF and a decline of 0.93% (95% CI: −1.52 to −0.34) in MMEF25-75%. An increase of 10 ug/m3 in PM2.5 was associated with an increase of 0.73 Hz (95% CI: 0.31 to 1.15) in Fres, an increase of 0.04 Kpa/(L/s) (95% CI: 0.01 to 0.06) in Z5 and an increase of 0.03 Kpa/(L/s) (95% CI: 0.00 to 0.05) in R5. And the more heavily PM2.5 of the district, the greater harm the impact.
Conclusion: Our findings suggested that short-term PM2.5 exposure may primarily affect both airway function and IOS in COPD patients.
Hierarchical clustering identifies oxidative stress-related subgroups for the prediction of prognosis and immune microenvironment in gastric cancer
Authors: Zhu Meng , Zhang Ning , Ma Jingwei
Published: November 2022

Background
Gastric cancer (GC) is a common digestive tract malignancy worldwide, exhibiting a high incidence of relapse and metastasis, and lack of effective therapy. Oxidative stress is involved in tumor progression and oncogenesis. Our study aimed to identify oxidative stress-related subgroups to classify GC patients and to develop oxidative stress-related genes for risk stratification in GC patients.
Methods
The mRNA expression profiles and corresponding clinical information of GC patients were acquired from TCGA-STAD and GSE84437 datasets. Oxidative stress-related subgroups were identified using consensus clustering analysis. GSEA and GSVA were performed to explore the underlying mechanisms, and xCell algorithm was used to assess the immune microenvironment and immune status of the GC subtypes. Prognostic risk model was constructed using TCGA-STAD dataset and validated using GSE84437 dataset.
Results
Two oxidative stress subtypes with significantly different survival were identified. C1 subtype exhibited activated immune signal pathway, high abundance of immune cell infiltration, high immune score, and high microenvironment score with a poor prognosis. Furthermore, an oxidative stress-related prognostic model could accurately predict the survival probability of GC patients. A nomogram containing patients’ sex, age, and the risk score could predict the survival of GC patients.
Conclusion
A novel classification system of GC patients was established based on oxidative stress-related signatures. This stratification could be used to accurately predict the prognosis of GC patients.
