RESUMEN

Lignans are a large category of polyphenolic compounds that have low molecular weight and are widely distributed in the plant kingdom. They have been recognized for their potential antioxidizing and antiproliferative action. One of the most important lignans is cubebin which is abundantly isolated from the leaves and seeds of Piper cubeba and Piper nigrum. Cubebin possesses numerous biological actions such as antileukemic, trypanocidal, antimycobacterial, analgesic, anti-inflammatory, histamine antagonist, antifungal, and antispasmodic. This review discusses the in vitro and in vivo pharmacological studies on cubebin related to biochemistry and pharmacological applications and it ensures that it widely shows therapeutic potential. We expect that these therapeutic actions will set a new track in the formation of novel biological agents by the derivatization of cubebin. This review will assuredly fascinate countless researchers to begin further experimentation that might lead to novel agents for the treatment and prevention of diseases.

RESUMEN

PURPOSE: To identify postpartum depression risk and describe experiences of women in the first 6 weeks after giving birth during the COVID-19 pandemic. STUDY DESIGN AND METHODS: Using a convergent mixed-methods approach, we recruited a convenience sample of women living in the United States who gave birth March 1, 2020 or later from social media Web sites. Participants completed the Postpartum Depression Screening Scale-Short Form and provided written answers to open-ended questions regarding their experiences at home with their new infant. RESULTS: Our 262 participants were on average 32.6 years of age, the majority were White (82%), married or partnered (91.9%), and college educated (87.4%). Mean postpartum depression score was 17.7 (SD = 5.9) with 75% scoring ≥14, indicating significant postpartum depressive symptoms. Qualitative content analysis revealed five themes: Isolation and seclusion continue; Fear, anxiety, and stress filled the days; Grieving the loss of normal: It's just so sad; Complicated by postpartum depression: A dark time; and There is a silver lining. Quantitative and qualitative findings provided a holistic view of women's depressive symptoms and experiences at home with their infants during the COVID-19 pandemic. CLINICAL IMPLICATIONS: Although policies that reduce risk of COVID-19 exposure and infection for patients and the health care team must continue to be implemented, the adverse effects of depressive symptoms on maternal-infant wellbeing within the context of increased isolation due to the pandemic need to be kept at the forefront. Nurses need to be aware of the consequences of women sheltering in place and social distancing on maternal-infant outcomes, particularly on depression and likelihood of breastfeeding.

RESUMEN

Piper longum (also known as Indian long pepper) is widely used in Ayurvedic, Siddha and Unani medicine systems. The principle bioactive compound of this plant is piperine, which mainly accumulates in the fruits called spikes. The report of piperine production by endophytic microbes isolated from Piper sp., motivated us to investigate the endophytic microbial diversity associated with the spikes vis-à-vis leaves (which contain negligible levels of piperine). This is the first report to use metagenomics approach to unravel the endophytic microbial diversity in P. longum. Our results indicate that 2, 56, 631 bacterial OTUs and 1090 fungal OTUs were picked cumulatively from both the tissues. Although bacterial and fungal endophytes occupy the same niche, remarkable differences exist in their diversity and abundance. For instance, the most abundant bacterial genera in spikes were Nocardioides and Pseudonocardia (Phylum Actinobacteria; reported to produce bioactive compounds); while, in leaves were Larkinella and Hymenobacter (Phylum Bacteriodetes). Likewise, the fungal endophytes, Periconia, Cladosporium and Coniothyrium (which have been earlier reported to produce commercially important metabolites including piperine), were also present in high abundance in spikes, in comparison to leaves. Further, the results of PICRUSt analysis reveal the high metabolic potential of spike-associated bacteria for secondary metabolism, namely biosynthesis of alkaloids (including pyridine/piperidine), terpenes, flavonoids and antibiotics. Therefore, our findings indicate that the endophytes abundant or unique in spikes could be explored for bioprospecting of novel/commercially important metabolites; an approach that has both ecological and economical benefits.

RESUMEN

BACKGROUND: Major nursing organizations, federal agencies, and researchers are recommending that all nurses be educated to at least the baccalaureate level. METHODS: This article reports the results of a qualitative study of the experiences of students enrolled in a direct associate's degree to baccalaureate degree nursing program. Based on multiple small group interviews conducted during an 18-month period, a multistep interpretive analytic process was used that ultimately described themes within a holistic view of the phenomenon. FINDINGS: The results showed an overarching theme of transformative change over time, centered within the "place" of the university. CONCLUSION: The study suggested that there are differences beyond additional coursework that describe a transformative process in associate's degree to baccalaureate degree education. An atmosphere, or "space created," for reflection on learning is significant to consider in the development of education programs.
