Morpho-nutritional status of micronutrient efficient wheat (Triticum aestivum L.) genotypes under changing environments.

In India, where cereal-based meals make up the majority of the daily diet, bread wheat (Triticum aestivum L.) is a key grain crop. Micronutrient deficiencies are a result of the lack of a diverse food culture in the nation. Genotypes of bread wheat that have been biofortified might be introduced to address this. It is anticipated that more information on the genotype x year interaction of these nutrients in grain will help us better understand the size of this interaction and perhaps even identify more stable genotypes for this attribute. Year revealed divergent responses to grain iron and zinc. Compared to zinc, iron showed lowest variation across year. Maximum temperature was the major determinant for the four traits. Iron is also significant correlation with zinc. Among the total fifty-two genotype, HP-06, HP-22, HP-24, HP-25, HP-33, HP-44, and HP-45 were found superior for zinc and iron content. These genotypes with high levels of zinc and iron can be used in a hybridization programme to further crop improvement. Wide-scale cultivation of the chosen genotype with high zinc and iron content in the agro-climatic conditions of Jammu will work with the region's current cropping systems.

In vitro anti-inflammatory, antidiabetic, antibacterial, and in silico studies of Ferruginan A isolated from Olea ferruginea Royle (Oleaceae).

Objective: Traditionally, Olea ferruginea Royle (Oleaceae) has been used as a painkiller and antidiabetic in various ailments. To provide a scientific background to this folklore the current study was designed to anti-inflammatory and antidiabetic effects of one of the isolated compound from this plant. Methods: Ferruginan A was isolated from the ethyl acetate extract of Olea ferruginea bark. This isolated molecule was subjected to in-vitro anti-inflammatory and antidiabetic effects using HRBCs and glucose uptake tests. The compound was also tested for molecular docking and ADMET study. Results: Regarding the anti-inflammatory effect, the tested compound demonstrated a 69.82 % inhibition at a concentration of 100 µg/mL, while the Ferruginan A (100 µl/mL) increased the uptake of glucose (3.79-71.86 %) in the yeast cell. Similarly, the zone of inhibition values of Ferruginan A (24.98 mm) against Escherichia coli were found to be comparable to standard (Imipenem: 31.09 mm). The mechanism of antidiabetic and anti-inflammatory effects was explored by using docking simulations performed on four molecular targets related to diabetes and inflammation. The results showed that the isolated compound may act as an antidiabetic agent by inhibiting the 5' Adenosine monophosphate-activated protein kinase (AMPK). While it also showed inhibition of anti-inflammatory targets COX-1, COX-2, and Tumor necrosis factor alpha (TNF-α). The ADMET prediction study revealed that isolated compound possesses favorable ADMET profile. Conclusion: It was concluded that Ferruginan A might be a significant anti-inflammatory and antidiabetic molecule.

Insights into metabolic and pharmacological profiling of Aspergillus ficuum through bioinformatics and experimental techniques.

BACKGROUND: Recently, numerous novel bioactive fungal metabolites have been identified that possess broad therapeutic activities including anti-inflammatory, antibiotic, antioxidant, and antitumor. The fungal mycochemicals as well as extracts have increased the interest of the scientific community in drug discovery research through a combination approach such as, molecular metabolic, pharmacological and computational techniques. Therefore, the natural fungus Aspergillus ficuum (A. ficuum) (FCBP-DNA-1266) was selected for metabolic and pharmacological profiling in this study. RESULTS: The metabolic profile of A. ficuum was explored for the first time and revealed the presence of bioactive compounds such as choline sulfate, noruron, hydroxyvittatine, aurasperone D, cetrimonium, kurilensoside, heneicosane, nonadecane and eicosane. Similarly, a pharmacological screen of A. ficuum was performed for the first time in in vivo and in vitro models. Interestingly, both the ethyl acetate and n-hexane fractions of A. ficuum were found to be more active against Bacillus subtilis among five tested bacteria with their zone of inhibition (ZOI) values of 21.00 mm ±1.00 and 23.00 mm ±1.00, at a concentration of 150 µgmL-1 respectively. Similarly, a significant decrease (P<0.001) and (P<0.01) in paw edema was observed in A. ficuum-treated animals at doses of 50 and 150 mgkg-1, respectively, reflecting its potent anti-inflammatory effect. Furthermore, the docking results supported the antibacterial and anti-inflammatory effects of A. ficuum. In addition, the crude extract demonstrated no acute toxicity and the highest percent radical scavenging was recorded for both n-hexane and ethyl acetate extracts. CONCLUSION: The metabolic profile of A. ficuum indicated the presence of biological relevant compounds. A. ficuum extract exhibited potent antibacterial and anti-inflammatory effects supported by docking results. Furthermore, A. ficuum extract demonstrated the highest percentage of radical scavenging activity along with no acute toxicity.

Synthesis of [1-8-NαC]-zanriorb A1, alanine-containing analogues, and their cytotoxic and anti-inflammatory activity.

The synthesis of the orbitide[1-8-NαC]-zanriorb A1, isolated from the medicinal plant Zanthoxylum riedelianum, was investigated by solution-phase macrocyclization of a linear peptide and on-resin solid-phase macrocyclization with an acylsulfonamide safety-catch linker. The solution-phase route produced a mixture of proline rotamers, and the main component was assigned as the trans, cis rotamer, identical to the natural product. The on-resin cyclization was less successful, producing mainly a linear peptide, and minor cyclic products as rotameric mixtures. Although the natural product was reported to be significantly cytotoxic against Jurkat leukemia T cells, our synthetic peptides were inactive, suggesting the presence of other rotamers or impurities in the naturally isolated material. Additional analogues of zanriorb A1 were synthesized in which proline and glycine residues were replaced with alanine. While these analogues were not cytotoxic, several of them inhibited the production of nitric oxide in lipopolysaccharide (LPS)-stimulated macrophages. The most active compound, cyclic[Ala5,6,8 ]-zanriorb A1 had an IC50 of 22 µM and was more potent compared with the standard NG-monomethyl-l-arginine acetate (L-NMMA) with an IC50 of 98 µM, indicating their strong anti-inflammatory potential.

A Comparative Study on Alvogyl and a Mixture of Black Seed Oil and Powder for Alveolar Osteitis: A Randomized Double-Blind Controlled Clinical Trial.

Introduction: Alveolar osteitis (AO) is the most common complication faced by exodontia patients and is usually seen 24-74 hours after tooth extraction, heralded by severe throbbing pain. Nigella sativa is commonly known as black seed known to have anti-inflammatory and antibacterial properties along with other reparative properties that enhance bone formation. This study aimed to evaluate and compare the effects of Alvogyl and a mixture of Nigella sativa powder and oil in the treatment of dry sockets. Materials and Methods: Sixty patients above the age of 18 and below 70 years, from both genders, who underwent extraction of teeth and were clinically diagnosed with a dry socket at the clinic of the College of Dentistry, Jouf University, Saudi Arabia, were included in this study. Pain scores were assessed after placement of the dressing at the following intervals: 5 minutes, 30 minutes, 60 minutes, 2nd day, 4th day, and 7th day. Patients were randomly allocated to three groups, namely, Group 1 (Alvogyl), Group 2 (mixture of Nigella sativa's powder and oil), and Group 3 (control). Pain relief and healing of the socket were compared between the three groups. The collected data were subjected to statistical analysis through Spearman's correlation test, independent t-test, ANOVA, and post hoc test. Results: A mixture of Nigella sativa powder and oil showed a statistically significant difference in relieving pain compared to the Alvogyl group. A mixture of Nigella sativa's powder and oil required fewer dressings when compared to the Alvogyl group. Conclusion: A mixture of Nigella sativa powder and oil is the more efficacious dressing material for the management of dry sockets compared to Alvogyl. It provides immediate and complete pain relief and fewer numbers of repeated visits.

Communication Skills (CS) training of physicians in China and its role in actual challenges of patient-physician relationship: a cross-sectional survey.

BACKGROUND: The Chinese healthcare system is affected by frequent disputes between physicians and patients. Although recent reforms have contributed towards improving the patient-physician relationship, distrust in physicians is still high. Communication skills (CS) training of physicians holds the key to improving patient confidence and diffusing stressful situations. This survey reports on the status of CS training in medical education in China, and the experiences and attitudes of physicians towards CS training. METHODS: A cross-sectional survey was conducted at medical institutions across China. A questionnaire developed for this study included the status of CS training, current aspects of patient-physician relationships, perceived own CS and patient-centeredness with Likert-scaled items from 1 (most negative) to 6 (most positive). Physicians' attitude towards CS training was measured with the Communication Skills Attitude Scale (CSAS) and its subscales PAS (Positive Attitude Scale) and NAS (Negative Attitude Scale). Data were analyzed descriptively and for group differences between the hospital level and operating vs. non-operating physicians. Binary logistic regression analysis was done to find associations explaining the occurrence of verbal and physical attacks and the role of CS attitudes. RESULTS: Out of 1080 questionnaires, 772 physicians met inclusion criteria. A total of 466/772 participants (60.4%) had received at least one CS training during their career. The participants rated the current situation related to patient-physician relationship in China as highly stressful (mean = 4.52, SD = 1.26, 95% CI: 4.43-4.60), experiencing verbal attacks in the past three years once a year in 372/772 cases (48.2%) and physical attacks 111/772 times (14.4%). The mean PAS was 62.96 (SD = 7.63, 95% CI: 62.41-63.47). Being female was associated with increased risk of verbal attacks (OR = 1.51, 95% CI: 1.01-2.25) while working in a tertiary hospital and showing high levels of PAS decreased this risk (OR = 0.62, 95% CI: 0.43-0.89, and OR = 0.95, 95% CI: 0.93-0.98). Having received a previous CS training decreased the odds of physical attacks (OR = 0.54, 95% CI: 0.35-0.83). CONCLUSIONS: A majority of Chinese physicians showed a high positive attitude towards CS training, were trained in CS and would value further training. Our results highlight that CS training is likely to promote patient-centered communication and reduce attacks against physicians. Both of these effects are to improve the patient-physician-relationship in the long run. More CS training should be offered to Chinese physicians, especially at secondary- and primary-care hospitals, where such practices remain infrequent.

Preparedness of Medical Graduates to serve in clinical settings independently: An exploratory qualitative study.

Objectives: To assess the preparedness of fresh medical graduates to perform the duties of an effective house officer in clinical settings independently. Methods: A qualitative exploratory descriptive study was conducted at a public sector tertiary care teaching hospital from September to October, 2021. A total of 14 interviews of the serving house officers were conducted (7 were from Medicine and Allied and seven were from Surgical and Allied). A verbatim Thematic analysis was done. Results: Initial analysis revealed 45 codes which were ultimately reduced to five main themes namely 1. Transition from studentship to house officers with sub-themes (1a) Sense of responsibility, (1b) Hectic and long duty hours, (1c) Proper orientation and guidance, 2. Deficient skill Training during educational journey with, (2a) Deficiency of practical and applied aspects, (2b) inconsistent and varying training patterns, (2c) self-perception and evaluation of preparedness, 3. Lack of awareness about Hospital settings and working system with sub-themes (3a) Support from other doctors, (3b) Being recognized as a doctor in hospital, 4. Inter-professional co-ordination gaps having sub-themes (4a) Communication gap, (4b) Mutual respect as a team and 5. Impact of COVID-19 with sub-theme (5a) Online teaching with no interaction and (5b) segue and progressive skill training. Conclusion: Medical graduates are not confident and well prepared to take the responsibility of patient care independently in clinical settings. Reforms in undergraduate curricula regarding skill training, hospital setup and workings and inter-professional education are advocated by young doctors to enhance their competencies for professional life.

Mental Health Among Medical Professionals During the COVID-19 Pandemic in Eight European Countries: Cross-sectional Survey Study.

BACKGROUND: The death toll of COVID-19 topped 170,000 in Europe by the end of May 2020. COVID-19 has caused an immense psychological burden on the population, especially among doctors and nurses who are faced with high infection risks and increased workload. OBJECTIVE: The aim of this study was to compare the mental health of medical professionals with nonmedical professionals in different European countries during the COVID-19 pandemic. We hypothesized that medical professionals, particularly those exposed to COVID-19 at work, would have higher levels of depression, anxiety, and stress. We also aimed to determine their main stressors and most frequently used coping strategies during the crisis. METHODS: A cross-sectional online survey was conducted during peak COVID-19 months in 8 European countries. The questionnaire included demographic data and inquired whether the participants were exposed to COVID-19 at work or not. Mental health was assessed via the Depression Anxiety Stress Scales32 (23.53)-21 (DASS-21). A 12-item checklist on preferred coping strategies and another 23-item questionnaire on major stressors were completed by medical professionals. RESULTS: The sample (N=609) consisted of 189 doctors, 165 nurses, and 255 nonmedical professionals. Participants from France and the United Kingdom reported experiencing severe/extremely severe depression, anxiety, and stress more often compared to those from the other countries. Nonmedical professionals had significantly higher scores for depression and anxiety. Among medical professionals, no significant link was reported between direct contact with patients with COVID-19 at work and anxiety, depression, or stress. "Uncertainty about when the epidemic will be under control" caused the most amount of stress for health care professionals while "taking protective measures" was the most frequently used coping strategy among all participants. CONCLUSIONS: COVID-19 poses a major challenge to the mental health of working professionals as a considerable proportion of our participants showed high values for depression, anxiety, and stress. Even though medical professionals exhibited less mental stress than nonmedical professionals, sufficient help should be offered to all occupational groups with an emphasis on effective coping strategies.

Berberine as a Potential Anticancer Agent: A Comprehensive Review.

Berberine (BBR), a potential bioactive agent, has remarkable health benefits. A substantial amount of research has been conducted to date to establish the anticancer potential of BBR. The present review consolidates salient information concerning the promising anticancer activity of this compound. The therapeutic efficacy of BBR has been reported in several studies regarding colon, breast, pancreatic, liver, oral, bone, cutaneous, prostate, intestine, and thyroid cancers. BBR prevents cancer cell proliferation by inducing apoptosis and controlling the cell cycle as well as autophagy. BBR also hinders tumor cell invasion and metastasis by down-regulating metastasis-related proteins. Moreover, BBR is also beneficial in the early stages of cancer development by lowering epithelial-mesenchymal transition protein expression. Despite its significance as a potentially promising drug candidate, there are currently no pure berberine preparations approved to treat specific ailments. Hence, this review highlights our current comprehensive knowledge of sources, extraction methods, pharmacokinetic, and pharmacodynamic profiles of berberine, as well as the proposed mechanisms of action associated with its anticancer potential. The information presented here will help provide a baseline for researchers, scientists, and drug developers regarding the use of berberine as a promising candidate in treating different types of cancers.

Evaluation of temporomandibular disorders among dental students of Saudi Arabia using Diagnostic Criteria for Temporomandibular Disorders (DC/TMD): a cross-sectional study.

BACKGROUND: Temporomandibular disorders (TMD) are a broad category of conditions arising from the various components of the temporomandibular joint complex. Bio-psychosocial model is the most accepted theory describing the etiopathogenesis of TMD. Dental students are vulnerable to psychological disorders, including anxiety, depression, and stress. Hence, the aim of the current study was to evaluate the prevalence and possible risk factors of TMD among dental students of various academic levels and explore the association of TMDs with demographic, academic, and psychosocial parameters. METHODS: A total of 246 students of a Saudi Arabia dental school were chosen for the study. After getting consent, all students were examined according to the Diagnostic Criteria for Temporomandibular Disorders, including Axis I and II components. RESULTS: The overall cross-sectional prevalence of TMD was found to be 36.99%. Pain arising from the jaw, temple, and the peri-auricular area were the most commonly reported symptoms and elicited signs during examination. Among the pain-related TMD, myalgia was the commonest diagnosed condition, whereas disc displacement with reduction was found prevalent in the intra-articular disorder category. Female (OR = 1.94; P = 0.004), married (OR = 1.74; P = 0.04), and students in clinical academic levels (OR = 1.65; P = 0.03) were found to have significantly increased risk of TMD. Among the psychosocial parameters, anxiety (OR = 1.55; P = 0.04) and parafunctional behaviours (OR = 2.10; P < 0.001) were shown to increase the risk of developing TMD. Students with any TMD reported to have significantly higher pain intensity levels (OR = 1.68; P = 0.01) and jaw functional limitations (OR = 1.45; P = 0.008). CONCLUSION: Dental students, especially in clinical levels were shown to pose a higher risk of developing TMD, hence strategies such as academic counselling and objective evaluation via rubrics should be planned to modify the administration of the curriculum, training methods and evaluation process.

Impact of an educational workshop on psychiatrists' attitude towards psychosomatic medicine.

BACKGROUND: Although psychosomatic medicine is not recognised as a medical specialisation globally, it has proven useful for treating many disorders in Germany. This paper reports on the impact of an educational workshop as a tool for raising awareness about psychosomatic medicine among international psychiatrists. METHODS: Psychiatrists from eight different countries were educated on psychosomatic medicine and psychotherapy during a 90-min workshop using a video, a slide presentation and an innovative teaching format called 'speed coaching'. Learning outcomes were assessed by analysing questionnaires completed by the participants before and after the workshop. RESULTS: Half of the participants who initially rejected the notion that psychosomatic medicine should be a specialisation on its own changed their minds in favour for it to be a separate discipline (p = 0.125). Awareness about which diseases and patients psychosomatic doctors deal with was increased. The intent for treatment of patients with eating disorders by a psychosomatic physician quadrupled among the participants (p = 0.004). CONCLUSIONS: A brief educational intervention can influence psychiatrists' decisions to opt for approaches by doctors specialized in psychosomatics for certain disorders. Further studies may explore why psychiatrists agree or disagree that psychosomatic medicine should be a separate specialisation on its own.

Mental Health Burden in Different Professions During the Final Stage of the COVID-19 Lockdown in China: Cross-sectional Survey Study.

BACKGROUND: COVID-19 resulted in considerable mental health burden in the Chinese general population and among health care workers at the beginning and peak of the pandemic. However, little is known about potentially vulnerable groups during the final stage of the lockdown. OBJECTIVE: The aim of this survey study was to assess the mental health burden of different professions in China in order to find vulnerable groups, possible influencing factors, and successful ways of coping during the last 4 weeks of the lockdown in Hubei Province. METHODS: A cross-sectional online survey asked participants about current residence, daily working hours, exposure to COVID-19 at work, and media preferences. We used a shortened version of the Depression, Anxiety and Stress Scale (DASS-21) to assess mental health. Further assessments included perceived stress (Simplified Chinese version of the 14-item Perceived Stress Scale), coping strategies for all participants, and specific stressors for health care workers. We followed the reporting guidelines of the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement for observational studies. RESULTS: The sample (N=687) consisted of 158 doctors, 221 nurses, 24 other medical staff, 43 students, 60 teachers/government staff, 135 economy staff, 26 workers/farmers, and 20 professions designated under the "other" category. We found increased depression (n=123, 17.9%), anxiety (n=208, 30.3%), and stress (n=94, 13.7%) in our sample. Professions that were vulnerable to depression were other medical staff and students. Doctors, nurses, and students were vulnerable to anxiety; and other medical staff, students, and economy staff were vulnerable to stress. Coping strategies were reduced to three factors: active, mental, and emotional. Being female and emotional coping were independently associated with depression, anxiety, or stress. Applying active coping strategies showed lower odds for anxiety while mental coping strategies showed lower odds for depression, anxiety, and stress. Age, being inside a lockdown area, exposure to COVID-19 at work, and having a high workload (8-12 hours per day) were not associated with depression, anxiety, or stress. WeChat was the preferred way of staying informed across all groups. CONCLUSIONS: By the end of the lockdown, a considerable part of the Chinese population showed increased levels of depression and anxiety. Students and other medical staff were the most affected, while economy staff were highly stressed. Doctors and nurses need support regarding potential anxiety disorders. Future work should focus on longitudinal results of the pandemic and develop targeted preventive measures.

Rotational culture and integration with amniotic stem cells reduce porcine islet immunoreactivity in vitro and slow xeno-rejection in a murine model of islet transplantation.

BACKGROUND: Pre-transplant modification of porcine islets may improve their suitability for clinical use in diabetes management by supporting graft function and reducing the potential for xeno-rejection. The present study investigates intra-graft incorporation of stem cells that secrete beta (ß)-cell trophic and immunomodulatory factors to preserve function and alter immune cell responsiveness to porcine islets. METHODS: Isolated porcine islets were maintained in a three-dimensional rotational cell culture system (RCCS) to facilitate aggregation with human amniotic epithelial cells (AECs). Assembled islet constructs were assessed for functional integrity and ability to avoid xeno-recognition by CD4+ T-cells using mixed islet:lymphocyte reaction assays. To determine whether stem cell-mediated modification of porcine islets provided a survival advantage over native islets, structural integrity was examined in a pig-to-mouse islet transplant model. RESULTS: Rotational cell culture system supported the formation of porcine islet:AEC aggregates with improved insulin-secretory capacity compared to unmodified islets, whilst the xeno-response of purified CD4+ T-cells to AEC-bearing grafts was significantly (P < 0.05) attenuated. Transplanted AEC-bearing grafts demonstrated slower rejection in immune-competent recipients compared to unmodified islets. CONCLUSIONS/INTERPRETATION: Rotational culture enables pre-transplant modification of porcine islets by integration with immunomodulatory stem cells capable of subduing xeno-reactivity to CD4+ T-cells. This reduces islet rejection and offers translational potential to widen availability and improve the clinical effectiveness of islet transplantation.

The chemistry and pharmacology of alkaloids and allied nitrogen compounds from Artemisia species: A review.

Several reviews have been published on Artemisia's derived natural products, but it is the first attempt to review the chemistry and pharmacology of more than 80 alkaloids and allied nitrogen compounds obtained from various Artemisia species (covering the literature up to June 2018). The pharmacological potential and unique skeleton types of certain Artemisia's alkaloids provoke the importance of analyzing Artemisia species for bioactive alkaloids and allied nitrogen compounds. Among the various types of bioactive Artemisia's alkaloids, the main classes were the derivatives of rupestine (pyridine-sesquiterpene), lycoctonine (diterpene), pyrrolizidine, purines, polyamine, peptides, indole, piperidine, pyrrolidine, alkamides, and flavoalkaloids. The rupestine derivatives are Artemisia's characteristic alkaloids, whereas the rest are common alkaloids found in the family Asteraceae and chemotaxonomically links the genus Artemisia with the tribes Anthemideae. The most important biological activities of Artemisia's alkaloids are including hepatoprotective, local anesthetic, ß-galactosidase, and antiparasitic activities; treatment of angina pectoris, opening blocked arteries, as a sleep-inducing agents and inhibition of HIV viral protease, CYP450, melanin biosynthesis, human carbonic anhydrase, [3H]-AEA metabolism, kinases, and DNA polymerase ß1 . Some of the important nitrogen metabolites of Artemisia include pellitorine, zeatin, tryptophan, rupestine, and aconitine analogs, which need to be optimized and commercialized further.

Chemo-preventive and therapeutic effect of the dietary flavonoid kaempferol: A comprehensive review.

Kaempferol, a natural flavonoid present in several plants, possesses a wide range of therapeutic properties such as antioxidant, anticancer, and anti-inflammatory. It has a significant role in reducing cancer and can act as a therapeutic agent in the treatment of diseases and ailments such as diabetes, obesity, cardiovascular diseases, oxidative stress, asthma, and microbial contamination disorders. Kaempferol acts through different mechanisms: It induces apoptosis (HeLa cervical cancer cells), decreases cell viability (G2/M phase), downregulates phosphoinositide 3-kinase (PI3K)/AKT (protein kinase B) and human T-cell leukemia/lymphoma virus-I (HTLV-I) signaling pathways, suppresses protein expression of epithelial-mesenchymal transition (EMT)-related markers including N-cadherin, E-cadherin, Slug, and Snail, and metastasis-related markers such as matrix metallopeptidase 2 (MMP-2). Accordingly, the aim of the present review is to collect information pertaining to the effective role of kaempferol against various degenerative disorders, summarize the antioxidant, anti-inflammatory, anticancer, antidiabetic, and antiaging effects of kaempferol and to review the progress of recent research and available data on kaempferol as a protective and chemotherapeutic agent against several ailments.
