Impacts of sugarcane industrial effluent as an alternate source of irrigation on growth, chlorophyll contents and antioxidants of different canola varieties.

The sugarcane industry often utilizes effluent for irrigation purposes; however, its intricate composition and elevated metal contaminants pose a potential risk of soil and crop contamination. Consequently, it is imperative to employ effective strategies to ensure the safe utilization of this resource for crop cultivation. One such strategy involves the dilution of sugarcane industry effluent. Dilution is a practical approach to mitigate its toxicity, minimizing its adverse impact on soil and crop health. That's why the current study explored the best dilution of sugarcane industrial effluent (SW) for cultivating canola varieties. A total of 15 canola varieties were cultivated 0%, 20%, 40%, 60%, 80%, and 100% SW. Results showed that 60% SW Faisalabad Canola and Punjab Canola improved germination, shoot length, root length, shoot fresh and dry weight, root fresh and dry weight, and chlorophyll contents compared to other treatments and control. AARI Canola and CON-III showed poor growth and chlorophyll contents under 60%SW. Dunkled and Oscar cultivars showed moderate improvement in growth and chlorophyll contents under 60SW. The 60% SW can be recommended for maximum growth benefits in canola cultivars, specifically Faisalabad Canola and Punjab Canola. At 20SW, the root dry weight of Faisalabad Canola increased by 2.7%, while Punjab Canola increased by 3.4%. Canola showed the highest increase in POD activity compared to the control, with a 55.45% increase, followed by Sandal Canola, with a 43.26% increase. However, additional field-level experiments are needed to determine the best cultivars suitable for optimal growth under 80SW and 60SW irrigation conditions.

Development of novel polymer haemoglobin based particles as an antioxidant, antibacterial and an oxygen carrier agents.

This innovative work aims to develop highly biocompatible and degradable nanoparticles by encapsulating haemoglobin (Hb) within poly-ε-caprolactone for novel biomedical applications. We used a modified double emulsion solvent evaporation method to fabricate the particles. A Scanning electron microscope (SEM) characterized them for surface morphology. Fourier Transform Infrared Spectroscopy (FTIR) and Ultraviolet-visible spectroscopies (UV-visible) elucidated preserved chemical and biological structure of encapsulated haemoglobin. The airproof equilibrium apparatus obtained the oxygen-carrying capacity and P50 values. The DPPH assay assessed free radical scavenging potential. The antibacterial properties were observed using four different bacterial strains by disk diffusion method. The MTT assay investigates the cytotoxic effects on mouse fibroblast cultured cell lines (L-929). The MTT assay showed that nanoparticles have no toxicity over large concentrations. The well-preserved structure of Hb within particles, no toxicity, high oxygen affinity, P50 value, and IC50 values open the area of new research, which may be used as artificial oxygen carriers, antioxidant, and antibacterial agents, potential therapeutic agents as well as drug carrier particles to treat the cancerous cells. The novelty of this work is the antioxidant and antibacterial properties of developed nanoparticles are not been reported yet. Results showed that the prepared particles have strong antioxidant and antibacterial potential.

Pancreatic ductal adenocarcinoma: exploring clinicopathological trends and racial disparities in a comprehensive U.S. population-based study.

INTRODUCTION: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy about 50% of PDAC are metastatic at presentation. In this study, we evaluated PDAC demographics, annual trend analysis, racial disparities, survival rate, and the role of different treatment modalities in localized and metastatic disease. METHODS: A total of 144,824 cases of PDAC were obtained from the SEER database from 2000 to 2018. RESULTS: The median age was 69 years, with a slightly higher incidence in males (52%) and 80% of all cases were white. Among cases with available data, 43% were grade III tumors and 57% were metastatic. The most common site of metastasis was the liver (15.7%). The annual incidence has increased steadily from 2000 to 2018. The overall observed (OS) 5-year survival rate was 4.4% (95% CI 4.3-4.6%), and 5 years cause-specific survival (CSS) was 5% (95% CI 5.1-5.4%). The 5-year survival with multimodal therapy (chemotherapy, surgery, and radiation) was 22% (95% CI 20.5-22.8%). 5-year CSS for the blacks was lower at 4.7% (95% CI 4.2-5.1%) compared to the whites at 5.3% (95% CI 5.1-5.4%). Multivariate analysis found male gender and black race associated with worse prognosis. Kaplan-Meier survival analysis found multimodal therapy to have the best outcomes in all three stages. CONCLUSION: PDAC is an aggressive malignancy with male gender and black race are associated with a poor prognosis. Surgery with chemoradiation was associated with the best overall survival. With steadily increasing rates of PDAC, improved treatment modalities are paramount to improving survival in these patients.

Rouleaux formation of white blood cells and platelets in leukemia / Formação de rouleaux de glóbulos brancos e plaquetas em leucemia

The objective of this study was to measure the effects of glucose and salt level on white blood cells, red blood cells and platelets (PLTs) in the blood of a leukemic patient by using a white light microscope. Different concentrations of glucose and salt in the range of 0 mM to 500 mM were admixed in the blood sample to prepare blood smear. We revealed that shape of erythrocytes, leukocytes and platelets changes and form aggregates. Increasing concentrations of glucose cause to increases aggregation process of white blood cells, red blood cells and platelets. And the increasing concentration of sodium chloride causes to increase rouleaux formation and aggregation of platelets but dehydration due to increased sodium chloride concentration causes to break the aggregation of white blood cells. Comparison of CBC reports of these samples with and without analytes shows that total leukocyte count (TLC) decreases gradually towards normal ranges of leukocytes which is favorable in the treatment of leukemia but at the same time decreasing level of hemoglobin HGB, mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and increasing level of red blood cell (RBCs) causes to reduce oxygen supply which is in favor of cancer growth and anemia. This work provides us the base for translation this in vitro study towards the in vivo case of blood microvasculature as a non-invasive methodology.

O objetivo deste estudo foi medir os efeitos da glicose e do nível de sal nos glóbulos brancos, glóbulos vermelhos e plaquetas (PLTs) no sangue de um paciente leucêmico usando um microscópio de luz branca. Foram misturadas diferentes concentrações de glicose e sal na gama de 0 mM a 500 mM na amostra de sangue para preparar esfregaço de sangue. Descrevemos que a forma dos eritrócitos, leucócitos e plaquetas muda e forma agregados. O aumento das concentrações de glicose aumenta o processo de agregação de glóbulos brancos, glóbulos vermelhos e plaquetas. E a crescente concentração de cloreto de sódio causa o aumento da formação de rouleaux e a agregação de plaquetas, mas a desidratação devido ao aumento da concentração de cloreto de sódio causa a quebra da agregação de glóbulos brancos. A comparação dos relatórios de CBC dessas amostras com e sem analitos mostra que a contagem total de leucócitos (TLC) diminui gradualmente para os intervalos normais de leucócitos, o que é favorável no tratamento da leucemia, mas ao mesmo tempo diminui o nível de hemoglobina HGB, hemoglobina corpuscular média (MCH ), a concentração média de hemoglobina corpuscular (MCHC) e o aumento do nível de glóbulos vermelhos (RBCs) reduz o suprimento de oxigênio, o que é a favor do crescimento do câncer e da anemia. Este trabalho fornece a base para a tradução deste estudo in vitro para o caso in vivo de microvasculatura de sangue como uma metodologia não-invasiva.
