The COVID-19 pandemic heightened the psychosocial impact of a cancer diagnosis as patients face concerns about the risk of infection and serious disease and uncertainties about the impact on their treatment. We conducted an online survey (n = 317) and focus groups (n = 19) with patients to examine their experiences with cancer care during the pandemic. Most survey respondents (68%) reported one or more disruptions or delays in care, including appointments switched to telehealth (49%). Patients perceived both benefits (e.g., convenience) and drawbacks (e.g., more impersonal) to telehealth. For many patients, COVID-19-related restrictions on bringing family members to support them during appointments was a major concern and left them feeling alone and vulnerable during treatment. Patients' self-reported coping during the pandemic was positively associated with age, education, and income (P < .05 for each) and better communication with their doctors during telehealth sessions (P < .001). Study findings highlight the importance of patient-centered care and communication to help patients cope with the challenges of the pandemic. Further research is needed to develop guidelines for use of telehealth as part of patient-centered cancer care.
COVID-19 大流行加剧了癌症诊断的社会心理影响，因为患者面临感染和严重疾病风险的担忧，以及对治疗影响的不确定性。我们对患者进行了在线调查（317 人）和焦点小组讨论（19 人），以了解他们在大流行期间的癌症治疗经历。大多数调查对象（68%）报告了一次或多次护理中断或延误，包括预约转为远程医疗（49%）。患者认为远程医疗既有好处（如方便），也有缺点（如更不人性化）。对于许多患者来说，COVID-19 相关的限制让他们在预约期间无法携带家人前来支持，这是他们最担心的问题，也让他们在治疗期间感到孤独和脆弱。患者在大流行期间的自我应对能力与年龄、教育程度和收入呈正相关（P P

Flower color patterns are attractive traits of floricultural plants. However, the mechanisms underlying these traits remain mostly unknown. Carnation ( Dianthus caryophyllus L.) and interspecific hybrids thereof exhibit many flower color patterns involving white margins on reddish petals, as observed in the cultivar ‘Minerva’. Flowers with white margins also have white abaxial surfaces. We studied the factors regulating the formation of white margins and a white abaxial surface in flowers through analyses of pigments and related gene expression. HPLC analysis revealed an absence of anthocyanins in white margins, although the accumulation of other flavonoid pigments (flavonols) was almost identical between the dark-red central and white marginal regions of petals. RNA-seq analyses of the dark red central regions and white marginal regions of ‘Minerva’ petals resulted in the extraction of 18 genes related to anthocyanin biosynthesis and transportation, including some transcription factors, as candidate regulatory genes for the formation of white margins. Further analysis of the expression of these genes by real-time RT-PCR and a comparison of two white-margin-flowered cultivars and three red-unicolor-flowered cultivars indicated that the expressions of two bHLH transcription factor genes and seven structural genes were positively correlated with anthocyanin accumulation. Although DcbHLH1 , which is a homolog of JAF13 in Petunia × hybrida , was expressed in both flower color groups, DcbHLH2 , a homolog of AN1 , was expressed only in white-marginal-flowered cultivars. Moreover, in the petals of ‘Minerva’, the expression of those nine genes was repressed in the abaxial epidermal layer without red pigmentation conferred by anthocyanins. Therefore, we could postulate that the localized repression of both bHLH genes is involved in the formation of white margins in carnation petals by inducing the absence of anthocyanin synthesis and that the white abaxial surface of the petals may result from similar regulatory mechanisms. In particular, DcbHLH2 could act as a key gene because of its restricted expression only in cultivars with white-margined flowers.

Lime ( Citrus aurantiifolia var. Pan) fruits were coated with Aloe vera gel (AVG) at 0 (distilled water as control), 10, 20, 30, 40, and 50% concentration as a 5 min dip and stored at ambient temperature (29 ± 1°C, 74 ± 5% RH) for 16 days. AVG coating markedly slowed fruit yellowing based on color scores and CIE L* , a* , and b* values, resulting in an increase in shelf life of about four days longer than that of the control (10 days). It did not significantly affect other fruit responses; AVG-coated and uncoated fruit had comparable weight loss, juice content, total soluble solids (TSS), titratable acidity (TA), and vitamin C content. Thus, AVG coating improved shelf life of lime primarily through delayed yellowing without adverse effects on other physicochemical attributes.
