Phytochemical Profiling and Pharmacological Evaluation of Leaf Extracts of Ruellia tuberosa L.: An In Vitro and In Silico Approach.

The present study was designed to appraise the photoprotective, antioxidant, and antibacterial bioactivities of Ruellia tuberosa leaves extracts (RtPE, RtChl, RtEA, RtAc, RtMe, and RtHMe). The results showed that, RtHMe extracts of R. tuberosa was rich in total phenolic content, i. e., 1.60 mgGAE/g dry extract, while highest total flavonoid content was found in RtAc extract, i. e., 0.40 mgQE/g. RtMe showed effective antioxidant activity (%RSA: 58.16) at the concentration of 120 µL. RtMe, RtEA and RtHMe exhibited effective in vitro antibacterial activity against Gram-negative bacteria (E. coli). In silico docking studies revealed that paucifloside (-11.743 kcal/mol), indole-3-carboxaldehyde (-7.519 kcal/mol), nuomioside (-7.275 kcal/mol), isocassifolioside (-6.992 kcal/mol) showed best docking score against PDB ID 2EX8 [penicillin binding protein 4 (dacB) from Escherichia coli, complexed with penicillin-G], PDB ID 6CQA (E. coli dihydrofolate reductase protein complexed with inhibitor AMPQD), PDB ID 2Y2I [Penicillin-binding protein 1B in complex with an alkyl boronate (ZA3)] and PDB ID 2OLV (from S. aureus), respectively. Docked phytochemicals also showed good drug likeness properties.

Disease Characteristics, Care-Seeking Behavior, and Outcomes Associated With the Use of AYUSH-64 in COVID-19 Patients in Home Isolation in India: A Community-Based Cross-Sectional Analysis.

Background: During the second wave of the COVID-19 pandemic in India, the Ministry of Ayush conducted a community study to provide therapeutic care to patients with asymptomatic, mild, and moderate COVID-19 in home isolation based on the empirical evidence generated on the efficacy of AYUSH-64 in COVID-19. Objective: To document disease characteristics, care-seeking behavior, and outcomes in patients with asymptomatic, mild, or moderate COVID-19 in home isolation who used AYUSH-64 for COVID-19. Methods: Cross-sectional analysis of the data generated through a community study conducted in India from 08 May to 31 August 2021 was performed to study the disease characteristics, care-seeking behavior during home isolation, clinical outcomes, adverse events, and the association between various risk factors and clinical recovery during the study period. The data were collected through semi-structured questionnaires, available in electronic data collection format at the baseline, 7, 14, and 21 days. A logistic regression was performed to explore the relationship between relevant variables and clinical recovery. Results: Data from 64,642 participants were analyzed for baseline assessment, and final analysis was done for 49,770 participants. The mean age of the enrolled participants was 38.8 ± 11.7 years, and 8.4% had co-morbidities. AYUSH-64 was utilized as an add-on to the standard care by 58.3% of participants. Comparable clinical outcomes were observed in participants utilizing AYUSH-64 either as a standalone or as an add-on to standard care, in terms of clinical recovery, disease progression, the requirement for oxygen supplementation, hospitalization, ICU admission, and need for ventilator support. Younger age, having no co-morbidities or substance abuse, and having been vaccinated were associated with early clinical recovery than those who were older and not vaccinated. Conclusions: The study findings suggest that AYUSH-64 use, either standalone or as an adjunct to standard care, in asymptomatic, mild, or moderate COVID-19 is associated with good clinical outcomes. Ayush services and interventions can be effectively integrated into the mainstream public health architecture to serve public health goals.

Are Low Serum Vitamin D Levels a Risk Factor for Advent of COVID-19 Associated Rhinocerebral Mucormycosis: A Preliminary Case Control Study.

To determine whether low serum vitamin D level is a risk factor for development of Rhinocerebral mucormycosis in COVID-19 afflicted patients. A case control study was conducted in a tertiary care hospital utilizing the archived records of COVID-19 afflicted Rhinocerebral mucormycosis cases and age and gender matched controls. The mean value (± standard deviation) of vitamin D level in patients with Mucormycosis was 19.65 ± 13.07 ng/ml and in control subjects it was 27.88 ± 18.04 ng/ml.There was a significant difference between groups (p = 0.02). Thus, low Vitamin D level may be implicated as a risk factor for the advent of mucormycosis in a COVID-19 afflicted patient and therefore Vitamin D supplements may be provided to such patients to achieve normal serum levels.

Effect of Vitamin D on Urinary Angiotensinogen Level in Early Diabetic Nephropathy.

BACKGROUND: Urinary angiotensinogen (UAGT) is supposed to be a marker of activation of the intrarenal renin- angiotensin system (RAS) system in early diabetic nnephropathy (EDN). Vitamin D has been studied as a negative regulator of the circulating and tissue RAS activity, so its supplementation may prevent the progression of diabetic nephropathy (DN). This study was planned to assess the RAS activation and effect of vitamin D supplementation in EDN progression by estimating the UAGT level. METHODS: A total of 103 EDN subjects were randomized in two groups to receive either cholecalciferol (54) or matching placebo (49) in a double-blind manner. All were subjected to routine investigations, urinary albumin-to-creatinine ratio (UACR), UAGT, vitamin D, and intact parathyroid hormone (iPTH) at the 0 and 6 months. A total 40 healthy controls were also included for assessment of the same investigations at 0 month. RESULTS: Significant reduction of UACR, UAGT, and iPTH level were corroborated with an increase in 25(OH) vitamin D level from 0 to 6 months (all four P < 0.001). After 6 months, the median [interquartile range (IQR)] of UAGT and UACR levels was significantly lower in the cholecalciferol group as compared to placebo group (p < 0.001 and P = 0.04, respectively). The median UAGT level was significantly higher in patients with EDN (cholecalciferol & placebo Group) than control group at 0 month (p = 0.001). CONCLUSION: Significantly higher UAGT levels in EDN supports the role of intrarenal RAS activation. A significant decrease in UAGT level in the cholecalciferol group supports the beneficial role of vitamin D supplementation in the progression of EDN.

Do methanotrophs drive phosphorus mineralization in soil ecosystem?

Experiments were carried out to elucidate linkage between methane consumption and mineralization of phosphorous (P) from different P sources. The treatments were (i) no CH4 + no P amendment (absolute control), (ii) with CH4 + no P amendment (control), (iii) with CH4 + inorganic P as Ca3(PO4)2, and (iv) with CH4 + organic P as sodium phytate. P sources were added at 25 µg P·(g soil)-1. Soils were incubated to undergo three repeated CH4 feeding cycles, referred to as feeding cycle I, feeding cycle II, and feeding cycle III. CH4 consumption rate k (µg CH4 consumed·(g soil)-1·day-1) was 0.297 ± 0.028 in no P amendment control, 0.457 ± 0.016 in Ca3(PO4)2, and 0.627 ± 0.013 in sodium phytate. Rate k was stimulated by 2 to 6 times over CH4 feeding cycles and followed the trend of sodium phytate > Ca3(PO4)2 > no P amendment control. CH4 consumption stimulated P solubilization from Ca3(PO4)2 by a factor of 2.86. Acid phosphatase (µg paranitrophenol released·(g soil)-1·h-1) was higher in sodium phytate than the no P amendment control. Abundance of 16S rRNA and pmoA genes increased with CH4 consumption rates. The results of the study suggested that CH4 consumption drives mineralization of unavailable inorganic and organic P sources in the soil ecosystem.

Toxic metal(loid)s contamination and potential human health risk assessment in the vicinity of century-old copper smelter, Karabash, Russia.

Active smelters release high concentration of multiple toxic metal(loid)s into the environment, degrading the soil cover and posing high risks to human health. The present study investigates Cu along with other metal(loids) such as As, Cd, Hg, Co, Mn, Pb and Zn in the soil collected from the vicinity of Cu smelter, Karabash, Russia, and potential health risks to local children and adults were assessed. The average concentrations of Cu, Zn, Pb, As, Cd, and Hg in the exposed soil were 2698, 1050, 702, 392, 9 and 2 mg kg-1, respectively, which was significantly (p < 0.05) much higher than reference soil: Cu(107), As(18), Cd(0.3), Hg(0.2), Pb(54) and Zn(125) mg kg-1. The enrichment factor (EF) for Cu, Hg, Pb and Zn showed significant enrichment, whereas very high enrichment was recorded for As (20.0) and Cd (27.6) suggesting the soil was severely affected by smelting activities. The pollution load index was tenfold higher than the acceptable level of one, whereas potential ecological risk factor showed very high potential risks of Cd and Hg, along with a considerable ecological risk of As and Cu. Very high ecological risk index of 1810 indicates severe degradation of environmental ecosystem. The results of EF, Pearson correlation and principle component analysis were complementary and suggest the anthropogenic source of contamination for Cu, As, Pb, Hg and Cd. The present result suggests As > Pb > Cu in the exposed soil were the major contributors for the health risks and account for 81%, 12% and 5%, and 77%, 12% and 8% of hazard quotient for children and adults, respectively. Noticeably, the health risks to local children dwelling in the vicinity of Cu smelter were 12 and 20 times higher than to adult and the acceptable level of one, respectively. Therefore, in order to reduce the health risk due to metal(loid)s, mitigation measures are needed to remediate the pollution of the exposed soil.

A pilot feasibility and acceptability study of yoga/meditation on the quality of life and markers of stress in persons living with HIV who also use crack cocaine.

BACKGROUND: Persons living with HIV (PLWH) who also use crack cocaine may have stressful, chaotic lives and typically do not engage in standard medical care that addresses a multitude of extenuating life circumstances. Yoga/meditation (YM) improves quality of life (QOL) and biomarkers of stress, but the effect of this intervention is almost unknown in PLWH, particularly those who use crack cocaine. OBJECTIVES: This pilot study sought to compare the feasibility and acceptability of 60-minute, twice-per-week sessions of YM for 2 months with those of no-contact control and to evaluate the effects of the intervention on QOL (according to the Short Form-36, Perceived Stress Scale [PSS], and Impact of Events Scale [IES]) and salivary cortisol and dehydroepiandrosterone sulfate (DHEA-S) among PLWH who use crack cocaine. DESIGN: Participants were randomly assigned to YM or no-contact control and were assessed at baseline, 2 months after the intervention, and 4 months' follow-up. RESULTS: The YM program was acceptable and feasible, with high overall attendance (89%) and individual participation in yoga sessions (83%). YM participants showed modest improvements on QOL. The PSS total score and the IES intrusion score improved significantly 2 months after the intervention, but cortisol and DHEA-S did not change. CONCLUSIONS: This pilot study showed a high level of feasibility and acceptability and modest effects on measures of QOL among PLWH who use crack cocaine. The results suggest utility of YM as a simple, safe, and inexpensive format to improve QOL in a population that has many medical difficulties and extenuating stressors.

Physiological and biochemical changes with Vamana procedure.

Vamana Karma (therapeutic emesis) primarily a Samshodhana Karma (purification procedure) is one of the five Pradhana Karmas (chief procedures) of Panchakarma. It is mentioned in Ayurvedic texts that a person after Samyak Vamana (proper Vamana) experiences lightness of the body, Hrit (precordium), Kantha (throat/voice), and Shirah (head) and weakness. This procedure is effectively used in healthy and ailing persons for purification of body and extraction of Doshas (especially Kapha) in Ayurvedic system. It has been found worth to observe the physiological and biochemical changes during Vamana and after the procedure to understand the effect/safety margins of the procedure in healthy volunteers.

Observations on Vamana procedure in healthy volunteers.

Vamana Karma is one of the five Pradhana Karmas of Panchakarma which is successfully used in treating Kaphaj disorders. Panchakarma is also indicated in healthy states. (C.Su. 16/13-16) for Shodhana. Textual references are available in Ayurvedic classics, but the procedure needs to be validated in the modern times when Ahara Shakti, Bala and Agni of the individuals have decreased considerably. So the effect of procedure was observed in 30 healthy volunteers of age group 18 to 60 years. Lakshanik, Vaigiki, Maniki and Antiki Shuddhi were observed and vomitus was analyzed macroscopically, microscopically and chemically.

Clinical observation on Greeva Stambha (cervical spondylosis) Chikitsa.

Greeva Stambha (A Vataja Disorder) simulates cervical spondylosis, which is a chronic degenerative condition of the cervical spine. Keeping in view the increasing incidence of this problem in modern society with more of desk- workers; an observational study was conducted on 22 patients of Greeva stambha vis-a-vis cervical spondylosis selected from OPD/IPD of CRIA, Punjabi-Bagh, New-Delhi, satisfying the inclusion criteria. The Vatahara treatment viz. Maha Yogaraj Guggulu 500 mg BD, Panchguna tail for local use and Nadi sweda (Local steam with Dashmoola Kwatha) were given for seven days. The results were assessed on the basis of symptomatic improvement using visual analog scale.

Insulin and insulin-like growth factor-1 increased in preterm neonates following massage therapy.

OBJECTIVE: To determine if massage therapy increased serum insulin and insulin-like growth factor-1 (IGF-1) in preterm neonates. STUDY DESIGN: Forty-two preterm neonates who averaged 34.6 weeks (M = 29.5 wk gestational age; M birth weight = 1237 g) and were in the "grower" (step-down) nursery were randomly assigned to a massage therapy group (body stroking and passive limb movements for three, 15-minute periods per day for 5 days) or a control group that received the standard nursery care without massage therapy. On Days 1 and 5, the serum collected by clinical heelsticks was also assayed for insulin and IGF-1, and weight gain and kilocalories consumed were recorded daily. RESULTS: Despite similar formula intake, the massaged preterm neonates showed greater increases during the 5-day period in (1) weight gain; (2) serum levels of insulin; and (3) IGF-1. Increased weight gain was significantly correlated with insulin and IGF-1. DISCUSSION: Previous data suggested that preterm infant weight gain following massage therapy related to increased vagal activity, which suggests decreased stress and gastric motility, which may contribute to more efficient food absorption. The data from this study suggest for the first time that weight gain was also related to increased serum insulin and IGF-1 levels following massage therapy. CONCLUSION: Preterm infants who received massage therapy not only showed greater weight gain but also a greater increase in serum insulin and IGF-1 levels, suggesting that massage therapy might be prescribed for all growing neonates.

Effect of carni Q-gel (ubiquinol and carnitine) on cytokines in patients with heart failure in the Tishcon study.

INTRODUCTION: There is evidence that both carnitine and coenzyme Q 10 (Co Q), which are important for the functioning of myocardial mitochondria, are deficient in patients with congestive heart failure, in association with increased pro-inflammatory cytokines. It is possible that supplementation with ubiquinol and L-carnitine may protect these patients by decreasing inflammation. SUBJECTS AND METHODS: In a randomized, double-blind, placebo-controlled trial, the effects of carni Q-gel (2250 mg/d L-carnitine and 270 mg/d hydrosoluble ubiquinol) were examined for 12 weeks. Thirty-one patients with heart failure received intervention (group A) and another 31 patients served as controls (group B). Serum levels of interleukin (IL)-6, tumour necrosis factor (TNF)-alpha and IL-10 could be studied among 29 patients in each group. Statistical analysis was conducted by analysis of variance and chi square test. RESULTS: Echocardiographic ejection fractions were lower at baseline (38.8 + 7.6 vs. 39.3 + 6.7% in the intervention and control groups, respectively) among both group of patients, indicating class II-IV heart failure. Serum concentration of interleukin-6 (IL-6), a pro-inflammatory cytokine, was high (18.7 +/- 5.8 vs. 15.0 +/- 3.3 pg/ml, normal 0.0-3.9) and IL-10 (anti-inflammatory) was normal (3.4 +/- 1.5 vs. 2.9 +/- 1.0 pg/ml, the normal range is 1.5-3.1 pg/ml) in both groups at baseline. After 12 weeks, there was a marked reduction in IL-6 in the intervention group without such changes in the control group (7.6 +/- 1.5 vs. 11.4 +/- 2.5 pg/ml, P < 0.01. IL-10 showed only the non-significant decrease in both groups from the baseline levels (3.2 +/- 1.0 vs. 2.8 +/- 0.9 pg/ml). TNF-alpha, which was comparable at baseline (17.6 +/- 4.3 vs. 20.0 +/- 5.3 pg/ml), also showed a greater decline in the carni Q-gel group compared to the placebo group (12.5 +/- 3.3 vs. 17.2 +/- 3.2 pg/ml, P < 0.05). Baseline serum CoQ levels (0.21 +/- 0.11 vs. 0.19 +/- 0.10 microg/ml) were low; however, after 12 weeks, serum CoQ showed a significant increase in the carni Q-gel group as compared to the control group (2.7 +/- 1.2 and 0.76 +/- 0.14 microg/ml, respectively). After 12 weeks of treatment, the quality of life visual analogous scale revealed that dyspnoea, palpitation and fatigue, (NYHA class II-III-IV), which were present at rest in all patients at baseline, showed beneficial effects in the intervention group compared to the placebo group. The six-minute walk test showed that there was a significant greater benefit in walking, from the baseline distance in the intervention group (208 +/- 15.8 vs. 281 +/- 20.6 metres, P < 0.02) compared to the placebo group (218.4 +/- 17.6 vs. 260.7 +/- 19.3 metres, P < 0.05). The symptom scale indicated that the majority of patients showed improvement in the intervention group compared to the control group (28 vs. 16 patients, respectively, P < 0.05). Three patients in the intervention group had nausea and vomiting, which were controlled with symptomatic treatment. CONCLUSIONS: These findings indicate that treatment with ubiquinol + L-carnitine can cause a significant reduction in the pro-inflammatory cytokines that are neurohumoural precursors related to sympathetic and parasympathetic activity, which is impaired in patients with heart failure. There was no adverse effect on IL-10. There was a significant improvement in quality of life as well as decrease in NYHA-defined heart failure.

A pilot study to test the effects of art-making classes for family caregivers of patients with cancer.

PURPOSE/OBJECTIVES: To test the effects of an art-making class (AMC) on reducing anxiety and stress among family caregivers of patients with cancer. DESIGN: A pretest and post-test quasi-experimental design. SETTING: A residential care facility near tertiary treatment centers in the southeastern United States. SAMPLE: The convenience sample of 69 family caregivers was aged 18-81 years (X = 48 years) and predominantly Catholic. Most had at least a high school education. Two-thirds were daughters, wives, or mothers of patients with cancer. METHODS: Participants completed a demographic data survey and a Beck Anxiety Inventory (BAI). Researchers collected a saliva sample from each participant to measure salivary cortisol, which indicates stress levels. Following pretesting, a two-hour AMC was delivered. Post-tests included a repeat BAI and a second saliva sample. MAIN RESEARCH VARIABLES: Anxiety and stress. FINDINGS: Anxiety was significantly reduced after AMC. Stress was reduced. CONCLUSIONS: The AMC appeared to reduce anxiety and stress. The addition of a control group and replication with larger numbers are suggested. The physiologic cortisol measure corroborated BAI findings but was difficult to obtain from some cultural groups and was expensive to analyze. IMPLICATIONS FOR NURSING: Family caregivers may benefit from participation in art-making interventions. Nurses should continue to investigate the use of creative approaches to promote holistic care.

Mood and hormone responses to psychological challenge in adolescent males with conduct problems.

BACKGROUND: Relations between stress hormones and antisocial behavior are understudied. METHODS: A subsample (n = 335) of at-risk males recruited in first grade for a longitudinal study were recruited at approximately 16 years of age for a laboratory study, including two psychological challenges: describing their worst experience on videotape, and a task in which a loud tone could be avoided. Measures of affect, urine, and saliva were collected multiple times before and after challenges. RESULTS: Negative affect increased following the worst-event challenge and decreased following the avoidance challenge. Mean conduct problems (CP) across ages 7-17 years were positively related to negative affect and inversely related to positive affect. CP were inversely related to post-challenge urinary epinephrine (E) levels when baseline E and potential confounds were controlled. Cortisol concentrations in saliva collected soon after the first challenge were positively related to CP in a post hoc subset of youths with extreme CP. CONCLUSIONS: Key findings A) associated persistent CP with more negative affectivity and less positive affectivity, B) replicated and extended prior findings of an inverse association of CP and urinary E, and C) suggested provocative hypotheses for future study relating CP, trauma history, trauma recall, and cortisol reactivity.

Effect on absorption and oxidative stress of different oral Coenzyme Q10 dosages and intake strategy in healthy men.

INTRODUCTION: The effect of various dosages and dose strategies of oral coenzyme Q(10) (Q(100) administration on serum Q(10) concentration and bioequivalence of various formulations are not fully known. SUBJECTS AND METHODS: In a randomized, double blind, placebo controlled trial 60 healthy men, aged 18-55 years, were supplemented with various dosages and dose strategies of coenzyme Q(10) soft oil capsules (Myoqinon 100 mg, Pharma Nord, Denmark) or crystalline 100 mg Q(10) powder capsules or placebo. After 20 days blood levels were compared and oxidative load parameters, malondialdehyde (MDA) and thiobarbituric acid reactive substances (TBARS) were monitored to evaluate bioequivalence. All the subjects were advised to take the capsules with meals. Blood samples were collected after 12 hours of overnight fasting at baseline and after 20 days of Q(10) administration. Compliance was evaluated by counting the number of capsules returned by the subjects after the trial. RESULTS: Compliance by capsule counting was >90%. Side effects were negligible. Serum concentrations of Q(10) (average for groups) increased significantly 3-10 fold in the intervention groups compared with the placebo group. Serum response was improved with a divided dose strategy. TBARS and MDA were in the normal ranges at baseline. After 20 days intervention in the 200 mg group TBARS and MDA decreased, but the decrease was only significant for MDA (Fig. 2). CONCLUSIONS: All supplementations increased serum levels of Q(10). Q(10) dissolved in an oil matrix was more effective than the same amount of crystalline Q(10) in raising Q(10) serum levels. 200 mg of oil/soft gel formulation of Q(10) caused a larger increase in Q(10) serum levels than did 100 mg. Divided dosages (2 x 100 mg) of Q(10) caused a larger increase in serum levels of Q(10) than a single dose of 200 mg. Supplementation was associated with decreased oxidative stress as measured by MDA-levels. Indians appear to have low baseline serum coenzyme Q(10) levels which may be due to vegetarian diets. Further studies in larger number of subjects would be necessary to confirm our findings.

Chronomics: circadian and circaseptan timing of radiotherapy, drugs, calories, perhaps nutriceuticals and beyond.

We suggest a putative benefit from timing nutriceuticals (substances that are both nutrients and pharmaceuticals) such as antioxidants for preventive or curative health care, based on the proven merits of timing nutrients, drugs, and other treatments, as documented, i.a., in India. The necessity of timing melatonin, a major antioxidant, is noted. A protocol to extend the scope of chronoradiotherapy awaits testing. Imaging in time by mapping rhythms and broader time structures, chronomes, for earliest diagnoses, for example detection of vascular disease risk, is recommended. The study of rhythms and broader chronomes leads to a dynamic functional genomics, guided by imaging in time of free radicals and antioxidants, amongst many other variables.
