Phospholipases D (PLDs) are important membrane lipid-modifying enzymes in eukaryotes. Phosphatidic acid, the product of PLD activity, is a vital signaling molecule. PLD-mediated lipid signaling has been the subject of extensive research leading to discovery of its crystal structure. PLDs are involved in the pathophysiology of several human diseases, therefore, viewed as promising targets for drug design. The availability of a eukaryotic PLD crystal structure will encourage PLD targeted drug designing. PLDs have been implicated in plants response to biotic and abiotic stresses. However, the molecular mechanism of response is not clear. Recently, several novel findings have shown that PLD mediated modulation of structural and developmental processes, such as stomata movement, root growth and microtubule organization are crucial for plants adaptation to environmental stresses. Involvement of PLDs in regulating membrane remodeling, auxin mediated alteration of root system architecture and nutrient uptake to combat nitrogen and phosphorus deficiencies and magnesium toxicity is established. PLDs via vesicle trafficking modulate cytoskeleton and exocytosis to regulate self-incompatibility (SI) signaling in flowering plants, thereby contributes to plants hybrid vigor and diversity. In addition, the important role of PLDs has been recognized in biotechnologically important functions, including oil/TAG synthesis and maintenance of seed quality. In this review, we describe the crystal structure of a plant PLD and discuss the molecular mechanism of catalysis and activity regulation. Further, the role of PLDs in regulating plant development under biotic and abiotic stresses, nitrogen and phosphorus deficiency, magnesium ion toxicity, SI signaling and pollen tube growth and in important biotechnological applications has been discussed.Cardiovascular ailments result in a great rate of mortality all over the world. Myocardial infarction is a common presentation of cardiovascular disease. The current work aimed to investigate and compare the cardioprotective potentials of methanolic extracts from the aerial parts from Bauhinia purpurea and Bauhinia madagascariensis in adrenaline-induced cardiotoxicity in rats. The rats were categorized into five groups as follows control group, adrenaline-treated group, Bauhinia purpurea extract + adrenaline treated group, Bauhinia madagascariensis+ adrenaline treated group, reference drug (captopril) + adrenaline treated group. The extracts as well as the reference drug were orally administered for 21 consecutive days. On day 22, adrenaline was injected as a single dose for 2 consecutive days. The adrenaline injection caused a significant increase (p  less then  0.05) in serum cardiac markers (ALT, AST, CK-MB, LDH), angiotensin-converting enzyme (ACE) and matrix metalloproteinase (MMP-9), inducible nitric oxide synthase (iNOS) activities, tumor necrosis factor-α (TNF-α) cardiac lipid peroxides (MDA) levels and a significant decline (p  less then  0.05) in cardiac reduced glutathione (GSH) levels compared to their corresponding controls. The pretreatment extracts significantly ameliorated (p  less then  0.05) these alterations. Histopathological investigations supported the biochemical data. Bauhinia madagascariensis extract exerted a significant anti-inflammatory activity than that of Bauhinia purpurea. In addition, Bauhinia madagascariensis extract revealed a significant inhibitory activity on ACE compared to that of Bauhinia purpurea, (p  less then  0.05). find more These data reveal that both extracts had a strong protective activity against adrenaline-induced cardiotoxicity via improving cardiac function, reducing ECG and histopathological changes that could be mediated in part through its anti-oxidant, anti-inflammatory effects, inhibition of ACE, MMP-9, and iNOS.Researchers have tended to focus on mind perception as integral to judgments of moral standing, yet a smaller body of evidence suggests that beauty may also be an important factor (for some people and animals). Across six studies (N = 1,662), we investigated whether beauty increases moral standing attributions to a wide range of targets, including non-sentient entities, and explored the psychological mechanism through which beauty assigns moral standing to targets. We found that people attribute greater moral standing to beautiful (vs. ugly) animals (Study 1 and Study 5a, preregistered) and humans (Study 2). This effect also extended to non-sentient targets, that is, people perceive beautiful (vs. ugly) landscapes (Study 3) and buildings (Study 4 and Study 5b, preregistered) as possessing greater moral standing. Across all studies, perceptions of purity mediated the effect of beauty on moral standing, suggesting that beauty increases the moral standing individuals place on targets through evoking moral intuitions of purity.

The purpose of this study was to examine how maintenance session attendance and 6-month weight loss (WL) goal achievement impacted 12-month 5% WL success in older adults participating in a community-based Diabetes Prevention Program (DPP) lifestyle intervention.

Data were combined from 2 community trials that delivered the 12-month DPP-based Group Lifestyle Balance (GLB) to overweight/obese adults (mean age = 62 years, 76% women) with prediabetes and/or metabolic syndrome. Included participants (n = 238) attended ≥4 core sessions (months 0-6) and had complete data on maintenance attendance (≥4 of 6 sessions during months 7-12) and 6- and 12-month WL (5% WL goal, yes/no). Multivariate logistic regression was used to estimate the odds of 12-month 5% WL associated with maintenance attendance and 6-month WL. Associations between age (Medicare-eligible ≥65 vs <65 years) and WL and attendance were examined.

Both attending ≥4 maintenance sessions and meeting the 6-month 5% WL goal increased the odds of meet program effectiveness and sustainability.

Meatpacking is dirty, dangerous, and demanding work. In the United States, the industry predominately employs people from racial/ethnic minority backgrounds and immigrants, with 45% of the workforce identifying as Hispanic/Latino. Little is known about how the work environment affects worker engagement in health-promoting activities; however, occupational health professionals are uniquely positioned to advance worker health, safety, and general well-being.

Hispanic/Latino meatpacking workers with work-related musculoskeletal pain and active health concerns were recruited to participate in a study to explore health, health behaviors, and the work environment. Five focus groups (

= 28) were conducted in Nebraska between March 2019 and February 2020. Thematic analysis using the Health Belief Model constructs was used to explain workers' health behaviors including utilization of occupational health services at their workplace.

Workers believed that there was little they could do to prevent and treat health problems.
