“…The rates found to maximize arugula yield were close to the 248.2 (PURQUERIO et al, 2007) and 240 (BENETT et al, 2019) kg ha -1 N to maximize the productivity of arugula, when it was cultivated in the field. The results corroborate information that arugula is very responsive to N fertilization (SILVA et al, 2020;STEINER et al, 2011).…”

Nitrogen Rates on Growth, Yield and Nitrate Foliar Content of Arugula

et al. 2021

Nitrogen is the second nutrient most demanded by arugula. However, the positive effect it has on yield can negatively impact the quality of this vegetable, with negative effects on human health. Two experiments (summer and autumn) were carried out to evaluate the effect of N rates (0, 50, 100, 150, 200 and 250 kg ha−1) on the arugula growth, yield and quality (nitrate content). Each experiment was set up in a randomized block design with four replications. Increasing rates of N reflected positively on leaf N content and thus, higher and desirable values of height, leaf number, leaf area and plant dry mass were obtained in both growing seasons. Consequently, the yield had significant increase, which N was maximized in summer (4.9 kg m−2) and autumn (2.6 kg m−2) and leaf N of 29.4 and 27.0 g kg−1, respectively, at rates of 250 and 213 kg ha−1 and both growing seasons. The higher rate the higher foliar nitrate content of arugula, in summer (2931.3 mg kg−1) and autumn (4218.4 mg kg−1). The foliar nitrate content in both crop season do not reach the risk level to human being heath.

“…The patient presented with fever of over a month’s duration, exertional dyspnoea and enlarged lymph nodes. As symptoms of early (acute and recent) HIV infection are usually non-specific and of short duration,3 4 individuals with HIV infection often do not present to doctors during these critical phases. However, his protracted symptoms led to multiple hospital visits, enabling early diagnosis.…”

“…In Japan, there were approximately 1000 new HIV infections in 2019, of which >70% were in men who had sex with men 2. Although starting antiretroviral treatment (ART) in the early HIV infection phase is important, individuals with HIV infection may be asymptomatic or may experience atypical symptoms,3 4 leading to diagnostic delay. Organising pneumonia (OP), which is classified as interstitial pneumonia, has various aetiologies from cryptogenic to secondary bacterial infections, certain drugs and collagen-related diseases 5.…”

Case of organising pneumonia in HIV infection

et al. 2022

A man in his 50s presented to his doctor with a fever, sore throat, cough, dysgeusia and dyspnoea of several days’ duration. Tests for HIV antigen, HIV antibody and HIV PCR were positive. He was referred to our hospital for initiation of antiretroviral therapy and bronchoscopy to clarify the cause of an abnormal lung shadow on chest CT. He was diagnosed with organising pneumonia, with concurrent HIV infection. His pulmonary lesions were remitted spontaneously, and he was administered a fixed-dose combination of tenofovir (50 mg), emtricitabine (200 mg) and bictegravir (25 mg) for HIV. This is a rare report of organising pneumonia with HIV infection. Physicians need to consider organising pneumonia when lung opacity is observed in a patient with HIV infection.

Biofertilization is a technique that uses plant and animal wastes to add organic matter and nutrients to the soil. It can also use microorganisms that can metabolize these by-products to facilitate their absorption by the plant roots. In this study, we tested the effects of rhizospheric bacteria inoculation (T1), a combination of rhizospheric bacteria with liquid fertilizer (T2) and uncombined liquid fertilizer (T3), on the growth, nutritional content, root tissue, and root cells of lettuce plants. The results showed significant positive differences in all treatments compared to control plants, in terms of morphological, nutritional, and productivity parameters. The combination of rhizospheric bacteria with liquid SEFEL fertilizer (T2) yielded the best results, showing increased fresh and dry weight, and diameter. There were no differences between treatments for nutritional content, but each treatment outperformed the control by more than 700% for all macronutrients. The best result was phosphorus content for T1, with 1272.22% more than control. Regarding root structure and ultrastructure, there was no variation in tissue organization compared to control plants, but increases in root hairs (T1), development of transfer cells (T2), and secondary growth (T3) were observed. Additionally, colonization of roots by rhizospheric bacteria was confirmed in all three treatments. In conclusion, this study suggests that inoculating with rhizospheric bacteria is a viable and environmentally friendly biofertilization for lettuce plants.
