Bee pollen is an apicultural product collected by honeybees from flower stamens and is consumed to help maintain a healthy diet. In this study, the chemical profiles of 11 Korean bee pollens were investigated using molecular networking analysis. This analysis elucidated the presence of two major clusters, hydroxycinnamoyl acid amides (HCAAs, molecular network 1 (MN1)) and flavonoid glycosides (MN2), in the bee pollen samples. The inhibitory properties of the bee pollens and the isolated HCAAs toward human catechol-O-methyltransferase (COMT), a key neurotransmitter involved in Parkinson's disease and depression, were determined. N1,N5,N10-(E)-tricaffeoylspermidine ((E,E,E)-1) exhibited the highest activity of the four compounds isolated, with an IC50 value 16 μM, and inhibited COMT competitively. Quantitative analysis of HCAAs showed that the amounts of N1,N10-dicaffeoyl-N5-p-coumaroylspermidine (2) and N10-caffeoyl-N1,N5-di-p-coumaroylspermidine (3) contributed to the observed differences in the COMT inhibitory activities of Korean bee pollens. This study may lead to the prevention and treatment of Parkinson's disease and depression using bee pollens.Developing materials that possess colorimetric responses to external stimuli is a promising strategy for addressing the current challenges in radiation dosimetry. Currently, colorimetric ionizing-radiation-responsive materials remain underexplored, and those with multistimuli response are rare. Herein, the integration of thorium cation and photoresponsive terpyridine carboxylate ligand gives rise to a thorium nanocluster, Th-101, which displays the second case of fluorochromic response and unprecedented piezochromic behavior among all actinide materials. The emission color of Th-101 exhibits a gradual transition from blue to cyan to green upon irradiation with accumulated dose, which renders colorimetric dosimetry of ionizing radiation based on a red-green-blue (RGB) concept. Further fabricating Th-101 into a custom-built optoelectronic device allows for on-site quantification of radiation dose with merits of ease of operation, rapid readout, and cost-effectiveness.Diterpenoid pyrones are a type of mainly fungal meroterpenoid metabolite consisting of a diterpene connected to a pyrone, some of which show potent bioactivity. selleckchem Through genome mining and heterologous expression, nine new diterpenoid pyrones, shearones A-I (1-9), were discovered from the fungus Eupenicillium shearii IFM 42152, and their biosynthetic enzyme activities were revealed. Some of these heterologously biosynthesized diterpenoid pyrones exhibited moderate antiaggregative ability against amyloid β42 in vitro.Facile synthesis of an imine compound through a greener route is still a challenging task. Industrial processes rely on the age-old Schiff reaction for the synthesis of imine, which are reversible and nongreen from an environmental viewpoint. Herein, cobalt-doped manganese tungstate with two different morphologies is synthesized and demonstrated as a recyclable catalyst for imine synthesis from the condensation of an aldehyde and an amine with 73% yield of an imine in a nonaqueous and nonacidic environment at room temperature. The high catalytic activity is attributed to cobalt doping, high surface area, strong acidic site, and the polar nature of the catalyst. The stability and recyclability test shows that the catalytic activity remains the same after several cycles, which is crucial from the industrial point of view. The formation of imine is found to follow an alternative mechanism in an irreversible manner with a polar four-membered intermediate unlike the conventional method. The demonstrated process has several advantages including irreversibility, "greener", environmental friendly, and energy-efficient.Aim To assess a psychosocial impact of the Coronavirus disease 2019 (COVID-19) on health care workers and to quantify the size of depression symptoms, anxiety and stress levels. Methods This cross-sectional study used an anonymous online survey questionnaire as a research instrument and it included 114 health workers of all profiles from the Sarajevo Canton employed in private and public institutions. The research was voluntary, non-commercial and all participants provided an oral informed consent. Depression, Anxiety and Stress Scale (DASS-21) questionnaire was used for assessing emotional status of depression, anxiety and stress. Results The mean age of participants was 40.5±8.44 years with malefemale ratio of 0.28. Prevalence of depression was 46.5%, anxiety61.4%, and 36.9% stress. Age and gender had no effect on emotional status, but it was revealed that women achieved higher depression, anxiety and stress scores than men (without statistical significance). The most notable effect on the emotional state was found for direct or indirect contact with COVID-19 patients. Medical workers in direct contact with COVID-19 patients achieved greater depression (p=0.005), anxiety (p=0.001), stress (p=0.030) and total DASS-21 (p=0.003) scores. Conclusion High prevalence of health workers affected by various psychological ailments during the COVID-19 pandemic was found. This evidence underscores the need to address adverse effects of the pandemic on mental health of health care workers.Coronavirus disease 2019 (COVID-19) is a highly hypercoagulable viral infection complicated as COVID-inflicted coagulopathy (CIC), that is associated with increased risk of morbidity and mortality. International guidelines recommend low molecular weight heparin (LMWH) to treat CIC in both in-hospital and in-home settings. However, in India, using subcutaneous LMWH may not be a feasible option for a vast majority of patients under home management. Additionally, while some evidence advocates the use of novel oral anticoagulants (NOACs), in hospitalized settings, most guidelines find no role of NOACs in hospital settings. On the other hand, the resource crunch faced in recent COVID-19 pandemic in India forced physicians to treat many patients in home settings. These patients had been usually prescribed NOACs for ease of administration and adherence. Therefore, there is a need to form a consensus on the use of NOACs to manage CIC in India.Non syndromic Anonychia congenita or congenital absence of finger and toe nails is a rare disorder known to occur due to autosomal recessive inheritance of mutation in the R-spondin-4 gene. We present a case of a 32 year old female born of a non-consanguineous marriage presenting with complete absence of finger and toe nails since birth and similar presentation in family members over four generations, suggesting an autosomal dominant inheritance.Several systemic anti-inflammatory and immunomodulatory agents were tried in the management of hyper inflammatory manifestations of COVID 19. JAK inhibitors have been widely deployed in rheumatology due to their benefits in managing uncontrolled inflammation. Tofacitinib is one of the most widely studied immunomodulators in rheumatology. We assessed the safety and efficacy of Tofacitinib in an open-labeled randomized control study, in addition to the standard of care (SOC) in hospitalized adults with mild to moderate COVID-19 pneumonia. Patients (n=100) with COVID 19 pneumonia admitted during October -December 2020 were randomly assigned to either control (N=50) (SOC treatment alone) or to study groups (N=50) receiving Tofacitinib in addition. Patients, reporting positive RT-PCR for SARS-COV2 and radiological evidence of pneumonia were hospitalized for over 7 days. The study group received Tofacitinib for 14 days irrespective of the discharge status and was followed up to 28 days. There was a greater relative reduction in levels of important markers of inflammation in the Tofacitinib group than in the control group (CRP78% vs 45%; Ferritin15% vs 10%; D. Dimer 37% vs 15%) although there were no differences in duration of hospitalizations or oxygen requirement. Tofacitinib, 10 mg was well-tolerated and was devoid of any serious adverse event. We are the first to record the benefits of Tofacitinib in India to our knowledge although a Brazilian study conducted around the same time showed mortality benefit in severe COVID. We conclude that Tofacitinib use is safe and aids in the reduction of the overwhelming inflammatory response during COVID-19 infections.Apart from the individual diseases, some patients also show overlapping manifestations of asthma and COPD. Nevertheless, the diagnosis of COPD is often delayed due to inaccessibility to spirometry; the prevalence of the asthma COPD overlap phenotype is rather high given the exposure to biomass smoke. Furthermore, the rates of exacerbations are twice as high compared to the patients with either of the diseases. A treatment strategy that would reduce the risk of exacerbations would contribute immensely to the management of such patients. Evidence of eosinophilia (marker of inflammation) in patients with asthma, asthma COPD overlap phenotype or COPD alone should prompt treatment with a combination of inhaled corticosteroids (ICS)/ long-acting β-agonists (LABA); several studies have shown improvement in the airflow limitation and reduction in the rate of exacerbations with salmeterol-fluticasone combination (SFC). Considering the association of COPD and cardiovascular diseases (CVD), it is critical to determine tlled asthma, asthma COPD overlap phenotype and COPD has been put forth.
Targeted HIV 1 viral load testing has been recommended in 2010 only for suspected cases of antiretroviral therapy failure. India is committed to achieve UNAIDS '90-90-90' target by 2020. The third 90 target was to ensure all people receiving antiretroviral therapy (ART) are virologically suppressed. Implementation of routine viral load testing in national programme helps us in assessing early treatment failure and the need to switch to second line therapy; thus eventually reducing drug resistance and improving patient outcomes.
Study was aimed to determine the proportion of patients responding to antiretroviral therapy, correlates of viral suppression & the discordance between virological and immunological failure.
Retrospective analysis.
As per the NACO policy, all patients diagnosed as HIV positive are started on antiretroviral therapy and are monitored regularly. The patient's adherence details are noted down during regular follow up visit and patient is referred for routine HIV 1 VL and/or CD4udy, 95.99% patients showed virological suppression indicating that the third "90"target is being exceeded.
The present study aimed to calculate the risk of osteoporotic fracture in patients of Rheumatoid arthritis (RA) by Fracture Risk Assessment Tool (FRAX) and its relationship with osteoporotic-specific risk factors.
This was a observational cross-sectional analytical study conducted from January 2019 to September 2020 where 185 patients, aged 40-90 years, who presented to the Rheumatology Clinic meeting the ACR/EULAR (2010) Classification Criteria for Rheumatoid Arthritis were included in the study and matched with 185 healthy individuals. We assessed the severity of the disease by using the DAS28 score. In addition, we evaluated the FRAX algorithm for all patients and controls to determine the 10-year fracture risk of major osteoporotic fracture and hip fracture.
RA patients had a significantly higher mean 10-year risk of major osteoporotic fracture (4.77 ± 5.04 vs 2.05 ± 1.84, P<0.05) and significantly higher mean 10-year risk of hip fracture (1.71 ± 2.81 vs 0.5 ± 0.95) (p<0.05).There was a significant positive correlation of duration of disease, previous fracture; parent fractured hip with major osteoporotic fracture (r=0.
