Synthesis and characterization of polyphenols functionalized graphitic hematite nanocomposite adsorbent from an agro waste and its application for removal of Cs from aqueous solution. CHEMOSPHERE 2022; 286:131493. [PMID: 34346332 DOI: 10.1016/j.chemosphere.2021.131493] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 06/26/2021] [Accepted: 07/06/2021] [Indexed: 06/13/2023]
Abstract
In this study, Polyphenols functionalized Graphitic Hematite Nanocomposite (PGHN) was used as an adsorbent to remove Caesium (Cs) ions from a simulated solution. The nanocomposite was produced by synthesizing iron oxide nanoparticles using orange peel extract (OPE) as the reducing and capping agent in the presence of graphite produced from sugarcane bagasse. The nanocomposite exhibited a scaly morphology and the mean particle size of rhombohedral structured hematite nanoparticles was found to be 148.9 nm. The simulated solution of Cs ions was treated with PGHN and the treatment conditions were optimized by batch method. The concentration of Cs ion in the treated solution was determined using atomic emission spectroscopy (AES). The maximum Cs adsorption of 97.95% was attained at an optimum condition of pH - 9.0 and adsorbent dose - 70 mg/mL for treatment period of 110 min. The experimental data of adsorption fitted well with pseudo 1st order kinetics and was favorable for both Langmuir and Freundlich isotherm models. The study reports a facile method for the production of nanocomposite using agro-wastes such as sugarcane bagasse and orange peels. The synthesized nanocomposite was used as an adsorbent for the removal of toxic Cs and can be further used for industrial wastewater treatment.

Abstract
India is the highest TB burden country in the world. The burden however is not uniform in different strata including tribal population - one of the key affected populations in the country. As the evidences from tribal population are hardly available, most of the policies and strategies implemented under National Tuberculosis Elimination Programme (NTEP) are usually based on the evidences from general populations. NTEP is continuously taking steps to strengthen TB services in tribal areas. The Social Action Plan including Tribal Action Plan is in place and the appropriate strategies are incorporated in the National Strategic Plan (NSP) to ensure universal access to quality TB services to vulnerable population groups. However, its implementation becomes challenging especially in tribal areas as different tribal groups have their own unique ways of dealing with health issues. These issues are therefore required to be addressed holistically involving all the stakeholders. In view of this a symposium was jointly organized by the Central TB Division (CTD), Govt. of India and ICMR - National Institute of Research in Tribal Health (NIRTH), Jabalpur on 17th and 18th December, 2019 at ICMR - NIRTH, Jabalpur. It provided an excellent platform for all the stakeholders from different parts of the country to share their experiences in tuberculosis particularly among marginalized populations. The recommendations emerged out of this interactive symposium highlight the sincere effort of NTEP to tackle TB situation in tribal population and show the way forward towards India's TB elimination goal by 2025 especially in hard to reach tribal areas.

Abstract
The first measurements of differential branching fractions of inclusive semileptonic B→X_{u}ℓ^{+}ν_{ℓ} decays are performed using the full Belle data set of 711 fb^{-1} of integrated luminosity at the ϒ(4S) resonance and for ℓ=e, μ. With the availability of these measurements, new avenues for future shape-function model-independent determinations of the Cabibbo-Kobayashi-Maskawa matrix element |V_{ub}| can be pursued to gain new insights in the existing tension with respect to exclusive determinations. The differential branching fractions are reported as a function of the lepton energy, the four-momentum-transfer squared, light-cone momenta, the hadronic mass, and the hadronic mass squared. They are obtained by subtracting the backgrounds from semileptonic B→X_{c}ℓ^{+}ν_{ℓ} decays and other processes, and corrected for resolution and acceptance effects.

Abstract
Background. Cystic hygroma (CH), occurs in 1/6000 live births and in 90% of cases develops in age less than 2 years old. They are mainly located in cervicofacial region. Adult-onset CH is very rare.
Objective. The aim of this study is to review literature to discuss the clinical presentation, diagnosis, and treatment of CH in adults through a case report of unilocular CH in the axillary region in an adult male from India.
Methods. A first case report of unilocular CH in axillary region in an adult male from India is being investigated.
Results. Here we report a case of unilocular CH in the axillary region in a 49-year-old male with a 14x16x8 cm cystic swelling in left axilla with a history of aspiration failure. Contrast-enhanced MRI (CEMRI) showed well-defined thin walled, unilocular cystic lesion which appeared hyperintense on T2 & STIR and hypointense on T1W1 and showed thin peripheral rim of enhancement on post contrast images. The patient underwent surgical excision and the diagnosis of a pathological CH was established. His postoperative recovery was uneventful and had no evidence of recurrence.
Conclusion. Due to rarity of adult-onset unilocular CH in axilla, its evaluation for prompt diagnosis and definitive treatment to prevent recurrence and complications is urgent. Furthermore, this is the first reported case from India which has been successfully managed at a peripheral hospital in Northeast-India and our report of this case contributes to the evidences supporting the role of CH in a differential diagnosis for masses in the adult axilla, especially in acute phase with no predisposing factors.

Abstract
We report a measurement of the D^{0} and D^{+} lifetimes using D^{0}→K^{-}π^{+} and D^{+}→K^{-}π^{+}π^{+} decays reconstructed in e^{+}e^{-}→cc[over ¯] data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy e^{+}e^{-} collider. The data, collected at center-of-mass energies at or near the ϒ(4S) resonance, correspond to an integrated luminosity of 72 fb^{-1}. The results, τ(D^{0})=410.5±1.1(stat)±0.8(syst) fs and τ(D^{+})=1030.4±4.7(stat)±3.1(syst) fs, are the most precise to date and are consistent with previous determinations.

Abstract
A search for the flavor-changing neutral-current decay B^{+}→K^{+}νν[over ¯] is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The data sample corresponds to an integrated luminosity of 63 fb^{-1} collected at the ϒ(4S) resonance and a sample of 9 fb^{-1} collected at an energy 60 MeV below the resonance. Because the measurable decay signature involves only a single charged kaon, a novel measurement approach is used that exploits not only the properties of the B^{+}→K^{+}νν[over ¯] decay, but also the inclusive properties of the other B meson in the ϒ(4S)→BB[over ¯] event, to suppress the background from other B meson decays and light-quark pair production. This inclusive tagging approach offers a higher signal efficiency compared to previous searches. No significant signal is observed. An upper limit on the branching fraction of B^{+}→K^{+}νν[over ¯] of 4.1×10^{-5} is set at the 90% confidence level.

Abstract
Abstract
Aim
In knee replacements, restoration of mechanical alignment is essential. Patients with extra-articular deformities (EAD) pose challenges in planning knee replacements. We present a method, based on our experience and review of literature on planning knee replacement surgery, in the presence of extra-articular coronal plane deformity of the tibia.
Method
Retrospective analysis was made of six patients with EAD of the tibia who underwent knee replacement at our centre. Mechanical axis of the tibia is considered and positioning of the tibia component is planned perpendicular to the mechanical axis of the tibia. The integrity of the collaterals determines the need for correction. Tibial resection >15mm from medial or lateral aspect of the tibia is an indication for corrective osteotomy prior to replacement surgery. The hip knee ankle angle (HKA) was noted. Pre-operative, post-operative clinical score, degree of constraints and post-operative complications were recorded. A post-operative long leg alignment radiograph was obtained.
Result
All patients had total knee replacement without correction of deformity. Adequate alignment of the limb and restoration of mechanical axis was achieved in all six patients without the need for correction of tibial deformity. All patients had improvement in their HKA angle and Oxford knee score. No re-operations were required, and no complications recorded.
Conclusions
Our study will help provide guidance on operative planning and decisions making for patients with extra-articular coronal plane tibial deformities.

Abstract
We investigate the low temperature magnetic properties of a S=5/2 Heisenberg kagome antiferromagnet, the layered monodiphosphate Li_{9}Fe_{3}(P_{2}O_{7})_{3}(PO_{4})_{2}, using magnetization measurements and ^{31}P nuclear magnetic resonance. An antiferromagnetic-type order sets in at T_{N}=1.3 K and a characteristic magnetization plateau is observed at 1/3 of the saturation magnetization below T^{*}∼5 K. A moderate ^{31}P NMR line broadening reveals the development of anisotropic short-range correlations concomitantly with a gapless spin-lattice relaxation time T_{1}∼k_{B}T/ℏS, which may point to the presence of a semiclassical nematic spin-liquid state predicted for the Heisenberg kagome antiferromagnetic model or to the persistence of the zero-energy modes of the kagome lattice under large magnetic fields.

Abstract
Platelets are the reservoir of growth factors and play a major role in several physiological processes, such as coagulation, angiogenesis, immune response, and tissue repair. Platelet concentrates are broadly classified into two groups depending on their fibrin content, namely platelet-rich plasma (PRP) and platelet-rich fibrin (PRF). They are further divided based on their leucocyte contents. The PRP is plasma containing supra-physiological concentrations of the platelets. The growth factors present in the PRP play a crucial role in the promotion of local angiogenesis, regulation of cellular activity, stem cell homing, proliferation and differentiation of different stem cells, and deposition of matrix proteins contributing to tissue regeneration. This review aimed to establish the therapeutic potential of PRP in canine medicine with a particular focus on the applications in ophthalmology, dermatology, and musculoskeletal disorders. A systematic literature review was performed to identify the literature published during the past 20 years (2001-2021) using authentic academic databases, such as PubMed, Science Direct, Google Scholar, and Scopus. In the initial search, 556 articles were identified and based on the specific inclusion and exclusion criteria, 59 articles were selected for further analysis. The clinical efficacy of PRP depends on the number of platelets and the growth factor concentration. The PRP-based biological therapy has broad clinical applications in musculoskeletal pathologies. It is a simple, safe, and cost-effective method that can be used to treat various diseases and disorders in canine practice. For example, PRP is used for managing corneal ulcers, corneal erosion, alkali burn, keratoconjunctivitis sicca, burn wounds, chronic wounds, cutaneous ulcers, acute traumatic bone fractures, tendinopathies, cartilage pathologies, osteoarthritis, and abdominal wall defects either as monotherapy or as an adjunctive therapeutic agent. In addition, PRP is widely used as a carrier of mesenchymal stem cells for transplanting into bone defects. Therefore, allogeneic PRP therapy can be considered a simple, safe, and cost-effective method for the treatment of various diseases and disorders in canine practice. The therapeutic application of PRP in canine medicine is limited in the present study due to the lack of consensus for collection, characterization, and clinical use. Hence, further studies are required to establish the actual worth of PRP-based regenerative strategies in canine medicine.

Abstract
BACKGROUND To determine if tuberculosis (TB) screening improves patient outcomes, we conducted two systematic reviews to investigate the effect of TB screening on diagnosis, treatment outcomes, deaths (clinical review assessing 23 outcome indicators); and patient costs (economic review). METHODS Pubmed, EMBASE, Scopus and the Cochrane Library were searched between 1/1/1980-13/4/2020 (clinical review) and 1/1/2010-14/8/2020 (economic review). As studies were heterogeneous, data synthesis was narrative. FINDINGS Clinical review: of 27,270 articles, 18 (n=3 trials) were eligible. Nine involved general populations. Compared to passive case finding (PCF), studies showed lower smear grade (n=2/3) and time to diagnosis (n=2/3); higher pre-treatment losses to follow-up (screened 23% and 29% vs PCF 15% and 14%; n=2/2); and similar treatment success (range 68-81%; n=4) and case fatality (range 3-11%; n=5) in the screened group. Nine reported on risk groups. Compared to PCF, studies showed lower smear positivity among those culture-confirmed (n=3/4) and time to diagnosis (n=2/2); and similar (range 80-90%; n=2/2) treatment success in the screened group. Case fatality was lower in n=2/3 observational studies; both reported on established screening programmes. A neonatal trial and post-hoc analysis of a household contacts trial found screening was associated with lower all-cause mortality. Economic review: From 2841 articles, six observational studies were eligible. Total costs (n=6) and catastrophic cost prevalence (n=4; range screened 9-45% vs PCF 12-61%) was lower among those screened. INTERPRETATION We found very limited patient outcome data. Collecting and reporting this data must be prioritised to inform policy and practice. FUNDING WHO and EDCTP.

Abstract
CONTEXT Mealtime insulin bolus is traditionally administered before meals in children with type 1 diabetes (T1D). Controlled studies on the use of pre-and postprandial insulin bolus have shown variable results. There are no real-world studies on postprandial bolusing of insulin in young children with T1D. METHODS Children with T1D aged <7 years were grouped into preprandial (Group 1) or postprandial (Group 2) groups according to the practice of prandial insulin use. Their retrospective data on mean glycosylated hemoglobin (HbA1c), hypoglycemic events, and diabetic ketoacidosis (DKA) episodes were compared. RESULTS Forty-four children (mean age 4.1±1.3 years, range 2-7 years) with mean diabetes duration of 2.0±0.7 years (range, 1-4 years) were identified; 23 (52.3%) belonged to Group 1 and 21 (47.7%) to Group 2. There were no differences in the mean HbA1c levels, mean hypoglycemic events, and DKA episodes between the two groups during a mean follow-up duration of two years. CONCLUSION Young children with T1D administered insulin bolus during or immediately after meals showed similar long-term glycemic control and diabetes-related adverse event profile compared to the premeal timing of insulin bolus. Larger real-world studies are needed on flexible insulin bolus timing in young children with T1D.

Abstract
Using data samples of 89.5 and 711 fb^{-1} recorded at energies of sqrt[s]=10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e^{+}e^{-} collider, we report measurements of branching fractions of semileptonic decays Ξ_{c}^{0}→Ξ^{-}ℓ^{+}ν_{ℓ} (ℓ=e or μ) and the CP-asymmetry parameter of Ξ_{c}^{0}→Ξ^{-}π^{+} decay. The branching fractions are measured to be B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})=(1.31±0.04±0.07±0.38)% and B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ})=(1.27±0.06±0.10±0.37)%, and the decay parameter α_{Ξπ} is measured to be 0.63±0.03±0.01 with much improved precision compared with the current world average. The corresponding ratio B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})/B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ}) is 1.03±0.05±0.07, which is consistent with the expectation of lepton flavor universality. The first measured asymmetry parameter A_{CP}=(α_{Ξ^{-}π^{+}}+α_{Ξ[over ¯]^{+}π^{-}})/(α_{Ξ^{-}π^{+}}-α_{Ξ[over ¯]^{+}π^{-}})=0.024±0.052±0.014 is found to be consistent with zero. The first and the second uncertainties above are statistical and systematic, respectively, while the third ones arise due to the uncertainty of the Ξ_{c}^{0}→Ξ^{-}π^{+} branching fraction.

Abstract
UNLABELLED Urban air pollution and exposure-related health impacts are being noticed and discussed very intensely in India. On the other hand, source-specific control is the primary focus for policymakers; however, diverse and complex sources make it difficult to immediately see the action and consequent impacts on better air quality. Many cities across the world have witnessed high air pollution levels at traffic junctions, more so in all Indian cities. Site-specific air pollution reduction can be a promising solution for managing the pollution level at highly polluted locations. CSIR-National Environmental Engineering Research Institute, India, has designed and developed Wind Augmentation and purifYing Unit (WAYU) to remove particulate and gaseous pollutants from urban hot spots such as traffic locations. In the present study, the authors attempted to evaluate the performance of two different designs of WAYU for the removal of particulate matters from polluted air at different traffic locations in Delhi City, the national capital territory of India. The performance analyses show that the current design of WAYU removes PM10 and PM2.5 concentrations in the range of 34-49% and 19-25%, respectively from the inlet air. The total PM collected from all WAYU devices was 34.19 kg from 120,557 operating hours' at all the sampling sites. The PM removal rate depends on the size-segregated particulate matter pollution load in the ambient air.

Abstract
OBJECTIVE To estimate the disease and economic burden of pertussis amongst hospitalised infants in India. DESIGN Multicentric hospital-based surveillance study. PARTICIPANTS Hospitalised infants with clinical suspicion of pertussis based on predefined criteria. OUTCOME MEASURES Proportion of infants with laboratory-confirmed pertussis, economic burden of pertussis amongst hospitalised infants. RESULTS 693 clinically suspected infants were recruited of which 32 (4.62%) infants had laboratory-confirmed pertussis. Progressive cough with post-tussive emesis (50%) and pneumonia (34%) were the common clinical presentations; apnea in young infants was significantly associated with pertussis. Infants with pertussis were more likely to be younger (median age 102.5 days vs.157 days) and born preterm (42.9% vs 24.5%). Almost 30% infants with pertussis had not received vaccine for pertussis with 50% of these infants aged less than 2 months. Pertussis was associated with higher costs of hospitalisation, pharmacy and loss of working days by caregivers as compared to non-pertussis cases. CONCLUSIONS Younger infants, those born preterm and those inadequately immunised against pertussis are at higher risk of pertussis infection. Timely childhood immunisation and introduction of maternal immunisation for pertussis can help in reducing the disease burden.

Abstract
Abstract
Study question
Does embryo vitrification or donor oocytes (DO) alter the histopathology of the placenta in ICSI singleton pregnancies with similar endometrial preparation?
Summary answer
Placentas from programmed cycles had significantly more immune/idiopathic-inflammation with vitrified-thawed embryos versus fresh transfer and significantly more maternal vascular-malperfusion(MVM) in DO versus autologous oocyte(AO) pregnancies.
What is known already
DO pregnancies and frozen embryo transfer(FET) pregnancies with programmed cycles are associated with hypertensive complications. As these complications are linked with abnormal placentation, comparing the placental histopathology in these pregnancies may point to a causative association.
Studies of placental histopathology in DO in comparison to AO pregnancies show a dysregulated immune process and vasculopathy. The hormonal milieu during implantation remains an important confounder.
Placental histopathology in fresh/ frozen cycles has recently shown variable results. To isolate the effect of embryo vitrification on placental histopathology, the donor oocyte model can provide valuable data, which till now is scarcely available.
Study design, size, duration
A prospective cohort study conducted in a tertiary center from 2018–2020.
Placental histopathology, pregnancy-outcomes were studied in 116 ICSI singleton pregnancies≥28 weeks.
Group1-Pregnancies with DO, by FET(n = 32) and freshET(n = 34) were compared to study the effect of embryo-vitrification.
Group2-Pregnancies by DO FET(n = 32) were compared to AO FET(n = 50) to study the effect of DO.
All patients had ICSI, cleavage embryo-transfer, programmed cycles and delivered at the same institute.
The placentas were examined by pathologists (blinded to the ET type).
Participants/materials, setting, methods
116 singleton pregnancies were followed for hypertensive disorders of pregnancy (HDP), preterm delivery(PTD<37weeks) and low birth-weight (LBW<2.5kg).
Placentas were examined for cord mal-insertions
Placental histopathology lesions were classified into 4 groups according to ‘Amsterdam criteria’ infectious-inflammatory, immune/ idiopathic-inflammatory, MVM, fetal vascular malperfusion (FVM).
Chi-square and t-tests were used to compare outcomes across groups. Adjusted odds ratio were calculated using logistic regression. Statistical significance set at P <.05, two-tailed.
Main results and the role of chance
No patient had a history of chronic hypertension/smoking. Group 1 Patients conceived by DO, with FET and freshET were comparable with regards to age (34.1 vs 36.4years, P=.07),BMI(26.7 vs 27.1 kg/m2,P=.6),nulliparity(81%vs82%,P=.9) HDP(25%vs29.4%,P=0.69),birth-weight(2.48 vs 2.47kg,P=.93) LBW(31.3%vs41.2%,P=.41)respectively
PTD was significantly less in donor FET versus donor freshET (6.3%vs47.1%P=.0002) Placental weight and cord mal-insertions were comparable for FET vs freshET (466 vs 486gms P=.03 12.5%vs23.5% P=.25)respectively. Amongst the placental histopathology lesions, immune/ idiopathic-inflammatory lesions were significantly more in the FET vs freshET group (37.5% vs 11.8%,P=.02)The other lesions were comparable infectious-inflammatory(6.3%vs17.6%,P=.16), MVM(75%vs58.8%, P=.16),FVM(18.8%vs17.6%,P=.9)
Group 2 Patients conceived by DO compared to AO by FET were significantly older and had a higher BMI (34.1vs31.7years,P=.02 ,26.7vs25.5 kg/m2,P=.002) respectively.
Nulliparity was comparable(81%vs92%,P=.15) Birth weight was significantly less in DO vs AO(2.4vs2.7kg,P=.02) HDP and LBW were significantly more in DO vs AO(25%vs8% ,P=.03, 31.3%vs 8%,P=.007),respectively. PTD was comparable(6.3%vs8.0%,P=.77). Placental weight was significantly less in DO vs AO (466 vs 513gms,P=.03) cord mal-insertions were comparable(12.5% vs 24%,P=.2) The MVM lesions were significantly more in the DO group compared to AO(75% vs 40%,P=.002)
The difference remained after adjusting for age/BMI/HDP (AOR 4.31;95% CI 1.24–14.8;P=.02). The rest of placental lesions were comparable in DO vs AO, infectious-inflammatory lesions(6.3%vs16%,P=.19) immune/idiopathic-inflammatory lesions(37.5%vs28%,P=.37) FVM(18.8% vs 12%,P=.4)respectively.
Limitations, reasons for caution
These findings are based on a small number of patients. The results observed need to be confirmed using a larger study sample.
Wider implications of the findings: Placentas in pregnancies by embryo-vitrification, in a DO-model, had significantly more immune/idiopathic-inflammation, the cause/significance of this needs to be explored. Placentas in DO-pregnancies had significantly more MVM-lesions and increased risk of HDP, emphasizing the clinical/histopathological link of DO with HDP and the need for counselling/preventive strategies for HDP in DO-pregnancie.

Abstract
AIMS The approach to potentially resectable non-small cell lung cancer (NSCLC) remains controversial. There is a benefit of neoadjuvant chemotherapy (NACT), but the ideal regimen is unknown. We evaluated the efficacy and safety of dose-dense NACT in potentially resectable NSCLC in this phase II trial. MATERIALS AND METHODS Paclitaxel at 80 mg/m2 on days 1, 8 and 15 with AUC-6 carboplatin on day 1, 3 weekly for four cycles was evaluated as NACT. Patients with Eastern Cooperative Oncology Group performance status 0-2, stage IIB and IIIA (with only non-bulky N2 nodes) were included. The primary end point was the objective response rate. Secondary end points included toxicity, progression-free survival, recurrence-free survival, complete resection rate and overall survival. The relative dose intensity (RDI) was calculated to define tolerability (CTRI/2016/05/006916). RESULTS In total, 37 patients were enrolled (median age 55 years). Most (78.8%) were smokers. Most patients had adenocarcinoma (57.6%) and stage IIIA disease (81.0%) according to the seventh American Joint Committee on Cancer staging system. Seventy-eight per cent of patients completed four cycles. The objective response rate was 75.6% with a complete response in 10.8%. The mean RDI of paclitaxel was 88.61%, with 68.0% of patients able to maintain an RDI ≥85.0%. In total, 187 toxicity events were recorded (120 grade 1, 64 grade 2 and three grade 3 events). Common toxicities were peripheral neuropathy (20.3%), myalgia (19.8%), nausea (15.7%) and neutropenia (10.2%). There were no treatment-related deaths. Seventeen patients underwent surgery (lobectomy 82.4%). After a median follow-up of 47 months (95% confidence interval 27-50.7 months), the median progression-free survival was 9.6 months (7.4-17.4) and overall survival was 29.2 months (16.0-37.2). CONCLUSION Dose-dense paclitaxel-carboplatin is feasible, safe and efficacious and should be evaluated further in potentially resectable NSCLC.

Abstract
Background and objectives Seroprevalence estimation of COVID-19 is quite necessary for controlling the transmission of SARS-CoV-2 infection. Seroprevalence rate in recovered COVID-19 patients help us to identify individual with anti-SARS-CoV-2 antibodies and its protective nature. The objective of present study was to evaluate seroprevalence of SARS-CoV-2 among potential convalescent plasma donors and analysis of their deferral reasons. Materials and methods A total 400 potential convalescent plasma donors were enrolled over five-month period for this prospective study. Inclusion criteria were lab confirmed COVID-19 recovered patients and 14 days of symptoms free period. All prospective plasmapheresis donors were tested for IgG SARS-CoV-2 antibody through chemiluminescent microparticle immunoassay, CBC, serum protein, blood grouping along with other required test for normal blood donation as per Drugs & Cosmetics Act. After pre donation testing and medical examination if donor was found to be ineligible for plasmapheresis was deferred. Seroprevalence rate was calculated by positive IgG antibody test results among the potential plasma donors. Results Seroprevalence rate was 87% for IgG SARS-CoV-2 antibodies in prospective convalescent plasma donors (recovered COVID-19 patients). There was no significant difference in seroprevalence rate between different sub-groups with respect to gender, age, blood groups, Rh factor, mode of treatment, day of Ab testing and repeat plasma donation. Most common reason for their deferral was absent IgG SARS-CoV-2 antibodies (13%) followed by absenteeism of eligible screen donors (6.7%), low Hb (1.7%) and poor veins for plasmapheresis (1.7%). Till five-month study period none of the plasmapheresis develop symptoms of reinfection with COVID-19. Conclusion In all, 13% recovered patients did not develop IgG antibodies after SARS-CoV-2 infection. SARS-CoV-2 IgG antibodies persist for quite some time and are protective against reinfection. More long-term serology studies are needed to understand better antibody response kinetics and duration of persistence of IgG antibodies.

Abstract
BACKGROUND AND AIMS Patients with pancreatic cancer often experience significant deterioration in nutritional status over time. Malnutrition is complex and multifactorial, with malabsorption, pain, toxic dependencies, co-morbidities and malignant processes all playing a role. The aims of this systematic review were to assess nutritional changes over time and identify tolerance of nutritional intervention, thus identifying potential areas for further research to improve patient outcomes. MATERIALS AND METHODS A systematic review of MEDLINE, EMBASE and PubMed was carried out in February 2020, identifying 2620 articles. After screening to exclude those reporting short-term measures, with only one data point, or in the wrong population, thirteen papers were selected for analysis (four trials in neo-adjuvant treatment, five in populations undergoing palliative treatment for pancreatic cancer, and four in mixed populations undergoing pancreatic resection). RESULTS Overall, studies were limited by predominantly retrospective designs, and poor control of potentially confounding variables. Meta-analysis could not be performed due to heterogenicity in study design and reporting methods. Surgery in mixed cohorts did not appear to result in weight loss. Only one small intervention study was identified. Patients with pancreatic cancer experienced a decline in nutritional status, with 44-63% of patients undergoing neoadjuvant chemotherapy having low muscle mass prior to starting treatment. CONCLUSION There is a paucity of data regarding nutritional intervention in pancreatic cancer. Future work should include the use of validated functional and clinical assessment tools to further explore the impact of nutritional intervention, and the relationship between nutritional status and outcome.

Abstract
Background:ANCA-associated vasculitis (AAV) with proteinase 3 (PR3) ANCA is genetically associated with HLA-DP [1], is often relapsing in nature, and has a predisposition for kidneys, lungs and ear-nose-throat involvement [2]. Despite the presence of PR3+ANCA, indicating CD4+T-cell help in the disease, the knowledge about autoreactive CD4+T cells is scarce. Activated T cells have been shown at site of inflammation [3] and involvement of proinflammatory cytokines in circulation is also reported [4, 5].Objectives:Identification of autoreactive T cells may help to identify the drivers of the immune responses and chronicity. We therefore aimed to investigate PR3-specific CD4+T-cell responses in peripheral blood of AAV patients with a focus on both phenotype and T-cell receptor (TCR) repertoires.Methods:The study included sixty-six patients: 26 with active PR3 autoantibody+ AAV, 21 with inactive but PR3+ AAV and 19 with inactive PR3- AAV. In-vitro cultures with PR3 protein were established to assess antigen-specific cytokine responses in a 3-color fluorospot assay. Deep immunophenotyping was performed by flow cytometry. Antigen-responsive CD4+ T cells were isolated and single cell TCRαβ sequences were generated and analyzed from PR3+ AAV patients (n=5) using a previously published protocol [6].Results:PBMCs from AAV patients demonstrated an HLA-DP associated cytokine responses to PR3 stimulation including IFN-γ and IL-10, but not IL-17A. This T-cell autoreactivity was found to be confined to a highly differentiated CD4+ T cell population characterized by perforin and GPR56 expression, implicating a cytotoxic feature of the response. Active disease involved a reduction in expression of several markers associated with cytotoxicity amongst the CD4+GPR56+ T cells. Their frequency was also negatively associated with the doses of prednisolone. A similar phenotype was shared with T cells activated by human cytomegalovirus (HCMV) peptides in the same patient cohort. Single cell sequencing of paired alpha beta T-cell receptors (TCRs) revealed different patterns of gene usage between PR3 and HCMV reactive T cells. Moreover, we could identify shared (public) PR3-reactive T-cell clones between different HLA-DPB1*04:01+ patients.Conclusion:PR3 is an autoantigen which provokes ANCA responses in AAV patients. Our study identified PR3-reactive CD4+ T cells at the level of their phenotype and TCR repertoire. The autoreactive CD4+ T cells, present in both active and inactive disease, implicate chronic antigen exposure and the persistence of long-lived T-cell clones. The presence of public autoreactive clones between HLA-DPB1*04:01+ patients suggests an active role for these cells in pathogenesis of AAV and validates the link with predisposed genotype.References:[1]Lyons PA, Rayner TF, Trivedi S, Holle JU, Watts RA, Jayne DR, et al.

Background-Iron deficiency is prevalent in heart failure patients and is associated with unfavorable clinical outcomes, irrespective of anemia status. The 2016 European Society of Cardiology (ESC) guidelines recommended intravenous ferric carboxymaltose (FCM) for the management of acute and chronic heart failure in symptomatic HF with reduced ejection fraction (EF).
Objective- To determine whether the correction of iron deficiency with ferric carboxymaltose confers better clinical outcomes in patients with acute and chronic heart failure
Methods-Electronic databases ( PubMed, Embase, Scopus, Cochrane) were searched from inception to December 28th, 2020. Unadjusted odds ratios (OR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance to be considered if the confidence interval excludes 1 and p < 0.05. The primary outcome of interest was cardiac mortality. Secondary outcomes included first hospitalisation due to worsening heart failure and any other cardiovascular (CV) reason.
Results-A total of five studies with 2091( FCM = 1125; placebo = 966) patients were included. Average follow-up period was 2 years. There was no difference in terms of cardiac mortality (RR 0.93, 95% CI 0.71–1.21; p = 0.57; I2 = 0) and hospitalizations for any CV reason (RR 0.83, 95% CI 0.32–2.16; p = 0.70; I2 = 83) with either group at the end of follow-up. As compared to placebo, FCM was associated with significant reduction in hospitalization due to worsening heart failure (RR 0.64; 95% CI 0.41-0.99; p = 0.04; I2 = 56)
Conclusion- Amongst patients with iron-deficient acute and chronic heart failure, treatment with ferric carboxymaltose reduced the risk of heart failure hospitalizations, with no apparent effect on the risk of cardiac mortality and hospitalizations for any other CV cause.

Abstract
Introduction March 11th, 2020 saw the World Health Organisation declare a global pandemic following the eruption of the novel coronavirus disease 2019. Unprecedented global demand for personal protective equipment (PPE) was complicated by limited availability and conflicting guidance from healthcare bodies. This study aimed to assess perceived confidence and knowledge of Public Health England’s PPE guidance amongst doctors of varying specialties and grades. Method A nationwide 11-point survey comprising of multiple-choice questions (MCQs) and a Likert scale assessing perceived confidence (1=not confident, 5=very confident) was disseminated to U.K. based doctors using multiple platforms. Results Data collated from 697 respondents revealed average perceived confidence was low. Notably, 59% felt they had received insufficient education regarding up-to-date guidance, with 81% advocating further training. Anaesthetics and ophthalmology were the highest and lowest scoring specialties in knowledge based MCQs, achieving 59% and 31% respectively. Subsequent statistical analysis revealed significant differences between specialties." Conclusions Ensuring consistency in published PPE guidance and education can develop doctor’s confidence and knowledge of appropriate PPE use. The absence of a unified consensus and global education regarding the use of PPE poses significant ramifications for patient and healthcare professional (HCP) safety whilst risking further depletion of already sparse resources.

Abstract
Asiatic cotton (Gossypium arboreum) cultivated as ‘desi cotton’ in India, is renowned for its climate resilience and robustness against biotic and abiotic stresses. The genome of G. arboreum is therefore, considered as a valued reserve of information for discovering novel genes or gene functions for trait improvements in the present context of cotton cultivation world-wide. In the present study, we carried out genome-wide analysis of LIM gene family in desi cotton and identified twenty LIM domain proteins (GaLIMs) which include sixteen animals CRP-like GaLIMs and four plant specific GaLIMs with presence (GaDA1) or absence (GaDAR) of UIM (Ubiquitin Interacting Motifs). Among the sixteen CRP-like GaLIMs, eleven had two conventional LIM domains while, five had single LIM domain which was not reported in LIM gene family of the plant species studied, except in Brassica rapa. Phylogenetic analysis of these twenty GaLIM proteins in comparison with LIMs of Arabidopsis, chickpea and poplar categorized them into distinct αLIM1, βLIM1, γLIM2, δLIM2 groups in CRP-like LIMs, and GaDA1 and GaDAR in plant specific LIMs group. Domain analysis had revealed consensus [(C-X2-C-X17-H-X2-C)-X2-(C-X2-C-X17-C-X2-H)] and [(C-X2-C-X17-H-X2-C)-X2-(C-X4-C-X15-C-X2-H)] being conserved as first and/or second LIM domains of animal CRP-like GaLIMs, respectively. Interestingly, single LIM domain containing GaLIM15 was found to contain unique consensus with longer inter-zinc-motif spacer but shorter second zinc finger motif. All twenty GaLIMs showed variable spatio-temporal expression patterns and accordingly further categorized into distinct groups of αLIM1, βLIM1, γLIM2 δLIM2 and plant specific LIM (DA1/DAR). For the first time, response of GaDA1/DAR under the influence of biotic and abiotic stresses were studied in cotton, involving treatments with phytohormones (Jasmonic acid and Abscisic acid), salt (NaCl) and wilt causing pathogen (Fusarium oxysporum). Expressions patterns of GaDA1/DAR showed variable response and identified GaDA2 as a probable candidate gene for stress tolerance in G. arboreum.

Abstract
We present a measurement of R_{K^{*}}, the branching fraction ratio B(B→K^{*}μ^{+}μ^{-})/B(B→K^{*}e^{+}e^{-}), for both charged and neutral B mesons. The ratio for the charged case R_{K^{*+}} is the first measurement ever performed. In addition, we report absolute branching fractions for the individual modes in bins of the squared dilepton invariant mass q^{2}. The analysis is based on a data sample of 711 fb^{-1}, containing 772×10^{6} BB[over ¯] events, recorded at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. The obtained results are consistent with standard model expectations.

Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment: DUNE Collaboration. THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS 2021; 81:322.

Abstract
The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM). Of the many potential beyond the Standard Model (BSM) topics DUNE will probe, this paper presents a selection of studies quantifying DUNE's sensitivities to sterile neutrino mixing, heavy neutral leptons, non-standard interactions, CPT symmetry violation, Lorentz invariance violation, neutrino trident production, dark matter from both beam induced and cosmogenic sources, baryon number violation, and other new physics topics that complement those at high-energy colliders and significantly extend the present reach.

Abstract
BACKGROUND: One of the most severe forms of TB, disseminated TB (dTB) is associated with significant mortality. A retrospective study was undertaken to assess the proportion of dTB among inpatient deaths and to describe the pathological spectrum of lesions. Associated comorbidities and missed dTB cases ante-mortem were also sought.METHODS: Data on autopsy-confirmed cases of dTB from over three decades (1988-2016) obtained from the departmental archives of the Post Graduate Institute of Medical Education and Research, Chandigarh, India, were reviewed for clinical details, as well as gross and histopathological findings. The proportion of autopsy-confirmed dTB were reported.RESULTS: During this period, a total of 243 autopsy-confirmed cases were retrieved. The organs most commonly involved in these cases were the lungs (90.1%), followed by the liver (72%), spleen (44%), kidneys (37%), bone marrow (17%), adrenals (12.2%), intestine (11.4%), pancreas (8.5%) and reproductive organs (6.9%). The brain was involved in 73.3% cases. In one third of cases, the diagnosis of TB was not suspected ante-mortem. Comorbid conditions were noted in 36.2% cases.CONCLUSION: A significant burden of dTB was noted among hospital inpatient deaths. Due to multi-organ involvement, dTB has atypical symptoms and may remain undiagnosed ante-mortem. Increased awareness and robust screening of TB cases are mandatory, particularly in patients with underlying comorbidities.

Evidence for X(3872)→J/ψπ^{+}π^{-} Produced in Single-Tag Two-Photon Interactions. PHYSICAL REVIEW LETTERS 2021; 126:122001.

Abstract
We report the first evidence for X(3872) production in two-photon interactions by tagging either the electron or the positron in the final state, exploring the highly virtual photon region. The search is performed in e^{+}e^{-}→e^{+}e^{-}J/ψπ^{+}π^{-}, using 825 fb^{-1} of data collected by the Belle detector operated at the KEKB e^{+}e^{-} collider. We observe three X(3872) candidates, where the expected background is 0.11±0.10 events, with a significance of 3.2σ. We obtain an estimated value for Γ[over ˜]_{γγ}B(X(3872)→J/ψπ^{+}π^{-}) assuming the Q^{2} dependence predicted by a cc[over ¯] meson model, where -Q^{2} is the invariant mass squared of the virtual photon. No X(3915)→J/ψπ^{+}π^{-} candidates are found.

Effect of germanium auto-diffusion on the bond lengths of Ga and P atoms in GaP/Ge(111) investigated by using X-ray absorption spectroscopy. JOURNAL OF SYNCHROTRON RADIATION 2021; 28:480-489.

Abstract
The germanium auto-diffusion effects on the inter-atomic distance between the nearest neighbors of the Ga atom in GaP epilayers are investigated using high-resolution X-ray diffraction (HRXRD) and X-ray absorption spectroscopy. The GaP layers grown on Ge (111) are structurally coherent and relaxed but they show the presence of residual strain which is attributed to the auto-diffusion of Ge from the results of secondary ion mass spectrometry and electrochemical capacitance voltage measurements. Subsequently, the inter-atomic distances between the nearest neighbors of Ga atom in GaP are determined from X-ray absorption fine-structure spectra performed at the Ga K-edge. The estimated local bond lengths of Ga with its first and second nearest neighbors show asymmetric variation for the in-plane and out-of-plane direction of GaP/Ge(111). The magnitude and direction of in-plane and out-of-plane microscopic residual strain present in the GaP/Ge are calculated from the difference in bond lengths which explains the presence of macroscopic residual tensile strain estimated from HRXRD. Modified nearest neighbor configurations of Ga in the auto-diffused GaP epilayer are proposed for new possibilities within the GaP/Ge hetero-structure, such as the conversion from indirect to direct band structures and engineering the tensile strain quantum dot structures on (111) surfaces.

Anti-piroplasmic activity of novobiocin as heat shock protein 90 inhibitor against in vitro cultured Theileria equi and Babesia caballi parasites. Ticks Tick Borne Dis 2021; 12:101696. [PMID: 33677232 DOI: 10.1016/j.ttbdis.2021.101696] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Revised: 02/16/2021] [Accepted: 02/21/2021] [Indexed: 11/19/2022]
Abstract
Theileria equi and Babesia caballi are the causative agents of equine piroplasmosis (EP). Currently, imidocarb dipropionate (ID) is the only available drug for treating the clinical form of EP. Serious side effects and incomplete clearance of infection is a major drawback of ID. Heat-shock proteins (Hsp) play a vital role in the life cycle of these haemoprotozoans by preventing alteration in protein conformation. These Hsp are activated during transmission of EP sporozoites from the tick vector (poikilotherm) to the natural host (homeotherm) and facilitate parasite survival. In the present study, we targeted the heat shock protein 90 (Hsp-90) pathway of T. equi and B. caballi by using its inhibitor drug - novobiocin. Dose-dependent efficacy of novobiocin on the growth of T. equi and B. caballi was observed in in vitro culture. Additionally, we examined dose-dependent cell cytotoxicity on host peripheral mononuclear cells (PBMCs) and haemolytic activity on equine red blood cells (RBC). In vivo organ toxicity of novobiocin was also assessed in a mouse model. The IC50 (50 % inhibitory concentration) value of novobiocin against T. equi and B. caballi was 165 μM and 84.85 μM, respectively. Novobiocin significantly arrested the in vitro growth of T. equi and B. caballi parasites at 100 μM and 200 μM drug concentration, respectively. In vitro treated parasites had distorted nuclear material and showed no further viability. Based on the equine PBMCs and RBC, the drug was found to be safe even at 1000 μM concentration and the CC50 (50 % cytotoxicity concentration) values were 11.63 mM and 261.97 mM. Very high specific selective index (SSI) values (70.47 and 1587) were observed for equine PBMCs and RBC, respectively. Organ-specific biochemical markers and histopathological examination indicated no adverse effect of the drug at a dose rate of 50 mg kg body weight in the mouse model. The results demonstrate the growth inhibitory effect of novobiocin against T. equi and B. caballi parasites and its safety for host cell lines with very high SSI. Hence, it can be inferred that the Theileria/Babesia Hsp-90 family are potential drug targets worthy of further investigation.

Abstract
BACKGROUND It is difficult to characterize the transition from relapsing-remitting multiple sclerosis (RRMS) to secondary progressive MS (SPMS), due to symptomatic variability across patients. Diagnosis of SPMS is prolonged and often established retrospectively, as it is based on patient clinical history and symptoms. This cross-sectional study aimed to identify MS neurologist reported clinical indicators deemed important in diagnosing SPMS in clinical practice. METHODS A web-based quantitative survey was conducted among MS-treating neurologists across the United States in January 2019. The questionnaire comprised of 17 questions evaluating primary clinical indicators used by neurologists in assessing patient progression to SPMS. Treatment approach and factors influencing treatment decision-making following SPMS diagnosis were also analyzed in the survey. RESULTS Overall, 300 neurologists completed the survey; most of the respondents were general MS-treating neurologists (63%) and from private care setting (58%). The overall respondents as well as MS-focused neurologists ranked patient history (45% and 42%, respectively) and patients' neurological exam (39% and 44%, respectively) as -primary clinical indicators of SPMS diagnosis. 57% of neurologists always or mostly switched disease modifying therapies after progression to SPMS, and mostly considered 3-6 months' assessment interval to diagnose SPMS. CONCLUSION The survey indicated that neurologists are able to recognize signs of SPMS within six months of symptomatic assessment. The diagnosis is primarily based on patient history among MS-treating neurologists. Therefore, continued education to neurologists may facilitate early diagnosis and timely introduction of effective treatment to manage the progression of SPMS.

Abstract
Attributable to the modernization of Artificial Intelligence (AI) procedures in healthcare services, various developments including Support Vector Machine (SVM), and profound learning. For example, Convolutional Neural systems (CNN) have prevalently engaged in a significant job of various classificational investigation in lung malignant growth, and different infections. In this paper, Parallel based SVM (P-SVM) and IoT has been utilized to examine the ideal order of lung infections caused by genomic sequence. The proposed method develops a new methodology to locate the ideal characterization of lung sicknesses and determine its growth in its early stages, to control the growth and prevent lung sickness. Further, in the investigation, the P-SVM calculation has been created for arranging high-dimensional distinctive lung ailment datasets. The data used in the assessment has been fetched from real-time data through cloud and IoT. The acquired outcome demonstrates that the developed P-SVM calculation has 83% higher accuracy and 88% precision in characterization with ideal informational collections when contrasted with other learning methods.
