Nitrogen (N) is a crop macronutrient of major importance, which affects both plant growth and yield. In this paper we discuss the humus content (%) and various soluble N forms (NO 3-, total N, nitrate-N, ammonium-N, and organic nitrogen) available in humus sand soil samples originating from the Pallag Experimental Station of Horticulture at the University of Debrecen, Hungary. We found 45.4% nitrate-N and 13.8% nitrite-N of total N content present in the soil. CPI-613 Considering the percentage distribution of soluble N forms present at the Pallag Experimental Station, we recommend using this soil in further pot experiments, given that this has optimal nutrient supply capacity. In addition, we examined possible statistical correlations between humus% and N forms.The novel coronavirus pneumonia (COVID-19) is still in a serious situation. There is no specific therapeutic drug for COVID-19. At present, drugs, including lopinavir/ritonavir, chloroquine phosphate, abidol, IFN-α atomization and ribavirin, are commonly used in clinical practice. However, further clinical trials are needed to evaluate the efficacy and safety of these drugs. Other potential drugs that may be effective for COVID-19, are worthy of attention, including IL-6 monoclonal antibody, tyrosine protein kinase 1/2 inhibitor, cell therapy drugs, etc. This paper reviews these potential therapeutic drugs for COVID-19.Objective To establish a noninvasive method for measuring upper airway critical closing pressure (Pcrit), so as to evaluate collapsibility of the upper airway during sleep. Methods Pcrit was determined through the use of a noninvasive positive/negative pressure (CPAP/CPNP) ventilator(with independent intellectual property rights) during stageⅡ of non-rapid eye movement sleep. For the direct measurement, Pcrit was the pressure below which the upper airway occluded. For the indirect measurement, nasal pressure was plotted against maximum inspiratory flow (Vimax), and linear regression was used to interpolate the pressure (i.e., Pcrit) at which zero flow occurred. Pcrit was attained from 19 subjects without obstructive sleep apnea syndrome(OSAS), and the correlation between direct and indirect measurement methods was analyzed. Results Directly measured and indirectly measured Pcrit showed no significant difference [(-7.02±2.74 vs (-7.26±2.96) cmH2O, 1 cmH2O=0.098 kPa; t=1.667, P>0.05] and had a highly significant correlation (r=0.986, P=0.000). Bland-Altman analysis revealed that the mean between-method difference was (0.24±0.53) cmH2O, and 95% limits of agreement ranged from -0.80 to 1.27 cmH2O, and all points except one were within limits of agreement. Conclusion Pcrit derived from the direct and indirect measurement methods does not differ, and both methods could be used for evaluating the upper airway collapsibility.Objective To explore the clinical characteristics of non-tuberculous mycobacterium(NTM) pulmonary disease complicated with tracheobronchial lesions. Methods From January 2014 to December 2018, there were 1 006 patients who were admitted to Guangzhou Chest Hospital for the first time and received examination by bronchoscopy. A total of 89 patients with complete data were selected, including 40 males and 49 females, aged 20 to 85 years, with 46 patients (52%) aged 60 years or older. The clinical symptoms and signs of the patients were analyzed with chest imaging, bronchoscopy and pathological examination results. Comparisons between groups were made by Chi-square test and t test. Results The number of patients with NTM complicated with tracheobronchial lesions accounted for 8.9%(89/1 006) of those hospitalized with NTM and received bronchoscopy during the same period. Clinical symptoms included cough and sputum (89/89), different degrees of hemoptysis or blood sputum (52/89), and shortness of breath (50/89). Chhial involvement characterized by scar stenosis, congestion and edema, mainly involving bilateral upper bronchi and the right lower bronchus.Treatment strategies for hormone receptor-positive (HR+ ), human epidermal growth factor receptor 2-negative (HER2- ) metastatic breast cancer in young women ( less then 40 years at diagnosis) have traditionally been extrapolated from data obtained from trials conducted either exclusively or predominantly in the postmenopausal setting. These young patients are usually treated with ovarian function suppression (OFS) + endocrine therapy (ET) ± targeted therapy, except if there is a concern about endocrine resistance or a need to gain rapid disease control due to the onset of visceral crisis. This review examines evidence that supports the use of a cyclin-dependent kinase 4/6 inhibitor, in combination with OFS and ET, when treating premenopausal or perimenopausal women with HR+ /HER2- metastatic breast cancer. This includes data from the MONALEESA-7 study (treating only premenopausal/perimenopausal women in the first-line setting), and the results of subgroup analyses from the PALOMA-3 and MONARCH-2 trials. We also consider a number of age-specific challenges that younger breast cancer patients can face, highlighting the importance of a multidisciplinary approach to ongoing care.

The Assessment of Learning Powered mobility use (ALP) tool including the ALP instrument and facilitating strategies, was developed for Driving to Learn. This therapeutic intervention aims to provide children and adults who have profound cognitive disabilities with opportunities to learn tool use through powered mobility practise. To allow for longer intervention periods, a partnership was developed between professionals supervising Driving to Learn and persons accompanying children or adults to their practice sessions. Accompanying persons (relatives or assistants) gradually took on shared responsibility for applying the intervention and conducting assessments with the ALP-instrument. The aim of this study was to test the inter-rater reliability of the ALP-instrument version 2.0 as applied in this novel partnership in assessment and intervention.

A psychometric analysis compared pair-wise assessments with the ALP-instrument version 2.0, made independently by professional supervisors and accompanying persons following each Driving to Learn session.
