Abstract
De-oiled rice bran is a good source of high-quality protein; however, the current practice of desolventization at high temperature (110-120 °C) denatures the protein, making its extraction difficult and uneconomical. The present study aims to investigate the effect of low temperature desolventization of de-oiled rice bran (LTDRB) on extraction, yield, and purity of protein and its comparison with protein obtained from high temperature desolventized de-oiled rice bran (HTDRB). The optimal conditions for preparation of protein from LTDRB were: extraction pH 11.00, extraction duration 52 min, and extraction temperature 58 °C resulting in an extraction efficiency, yield, and purity of 54.0, 7.23, and 78.70%, respectively. The LTDRB showed a positive impact on the color, solubility, foaming capacity and stability of protein whereas the absorption and emulsification properties were better for HTDRB protein. Significant decrease in enthalpy (ΔH) for denaturation was observed for LTDRB protein as compared to HTDRB protein. Scanning electron microscopy analysis revealed that HTDRB protein was more compact than LTDRB protein. LTDRB protein had smaller particle size distribution than HTDRB. Study suggested that low temperature desolventization can result in higher protein extraction with better physico-chemical, structural, and functional properties of protein obtained from DRB.

Abstract
Bitter gourd (Momordica charantia L.), belonging to family Cucurbitaceae, is a good source of carbohydrates, proteins, vitamins, minerals, and bioactive compounds. In the present study, fruits (and its parts-epicarp, mesocarp, endocarp, seed, and whole fruit) of 56 accessions and 4 cultivars of Momordica spp. were assayed and compared for macro-minerals magnesium (Mg), potassium (K), sodium (Na), phosphorus (P), and calcium (Ca), and microminerals iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu). Potassium was the most abundant macro-mineral found in whole fruit ranging from 78.40 to 483.49 mg/100 g dry weight (DW), followed by Mg (13.23-101.70 mg/100 g DW) in epicarp, P (32.22-98.24 mg/100 g DW) in endocarp, Ca (23.41-71.39 mg/100 g DW) in whole fruit, and Na (6.09-18.56 mg/100 g DW) in epicarp. The concentration of microminerals was recorded higher in seeds compared to other fruit parts. Levels of Fe were higher (0.76-6.14 mg/100 g DW), followed by Zn (0.87-2.64 mg/100 g DW), Cu (137.68-525.45 µg/100 g DW), and Mn (46.92-179.05 µg/100 g DW). The analysis depicted bitter gourd to be a potential source of both macro-minerals (K and Mg) and microminerals (Fe and Zn). The consumption of bitter gourd could be a health-promoting strategy to meet daily dietary intake requirements of essential minerals for human health.

Abstract
Honey bee products comprise various compounds, including honey, propolis, royal jelly, bee pollen, bee wax and bee venom, which have long been recognized for their pharmacological and health-promoting benefits. Scientists have discovered that periodontal disorders stem from dental biofilm, an inflammatory response to bacterial overgrowth produced by dysbiosis in the oral microbiome. The bee products have been investigated for their role in prevention of oral diseases, which are attributed to a myriad of biologically active compounds including flavonoids (pinocembrin, catechin, caffeic acid phenethyl ester (CAPE) and galangin), phenolic acids (hydroxybenzoic acid, hydroxycinnamic acid, p-coumaric, ellagic, caffeic and ferulic acids) and terpenoids. This review aims to update the current understanding of role of selected bee products, namely, honey, propolis and royal jelly, in preventing oral diseases as well as their potential biological activities and mechanism of action in relation to oral health have been discussed. Furthermore, the safety of incorporation of bee products is also critically discussed. To summarize, bee products could potentially serve as a therapy option for people suffering from a variety of oral disorders.

Abstract
The objective of this study was to compare the effectiveness of buffered and non-buffered local anaesthetic (LA) following inferior alveolar nerve block (IANB). This study was conducted at Usmanu Danfodiyo University Teaching Hospital Sokoto from June 2020 to January 2021. Subjects were randomised into Groups A and B. Group A received 2 ml of freshly prepared 2% lignocaine with 1:100,000 adrenaline buffered with 0.18 ml of 8.4% sodium bicarbonate solution while those in Group B received non-buffered 2% lignocaine with 1:100,000 adrenaline LA solutions. The onset of action of the LA was assessed by subjective and objective methods, while pain at the injection site was assessed using a numerical rating scale. Data obtained were analysed using statistical package for social sciences (IBM SPSS) version 21. The mean (SD) ages for Groups A and B were 37.4 (14.9) and 40.1 (14.4) years, respectively. The mean (SD) onset times of the LA by subjective testing were 126 (31.7) and 201 (66.8) seconds for Groups A and B, respectively. Similarly, the mean (SD) onset times of the local anaesthesia by objective testing for Groups A and B were 186 (41.0) and 287 (85.0) seconds, respectively, and both were significant (p<0.001). Pain at the injection site assessed objectively and subjectively were also statistically different (p<0.001). The findings of this study suggest that buffered LA is more effective than non-buffered LA of the same composition when used for IANB particularly concerning a significantly faster rate of onset and less pain at the injection site.

Abstract
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an autosomal dominant small-vessel disease caused by mutations of the NOTCH3 gene. It typically presents with migraine, recurrent brain ischaemia, and cognitive disorders. Seizures rarely present as the initial manifestation, with non-convulsive status epilepticus being even less frequent. We present a series of 3 related patients with this arteriopathy, 2 of whom presented status epilepticus as a manifestation of the disease.

Abstract
BACKGROUND In order to obtain more economic gains, some food products are adulterated with low-cost substances, if they are toxic, they may pose public health risks. This has called forth the development of quick and non-destructive methods for detection of adulterants in food. Near-infrared reflectance spectroscopy (NIRS) has become a promising tool to detect adulteration in various commodities. We have developed rapid NIRS based analytical methods for quantification of two cheap adulterants (grass pea and pea flour) in a popular Indian food material, chickpea flour. RESULTS The NIRS spectra of pure chickpea, pure grass pea, pure pea flour and adulterated samples of chickpea flour with grass pea and pea flour (1-90%) (w/w) were acquired and preprocessed. Calibration models were built based on modified partial least squares regression (MPLSR), partial least squares (PLS), principal component regression (PCR) methods. Based on lowest values of standard error of calibration (SEC) and standard error of cross-validation (SECV), MPLSR-NIRS models were selected. These models exhibited coefficient of determination (R2 ) of 0.999, 0.999, SEC of 0.905, 0.827 and SECV of 1.473, 1.491 for grass pea and pea, respectively. External validation revealed R2 and standard error of prediction (SEP) of 0.999 and 1.184, 0.997 and 1.893 for grass pea and pea flour, respectively. CONCLUSION The statistics confirmed that our MPLSR-NIRS based methods are quite robust and applicable to detect grass pea and pea flour adulterants in chickpea flour samples and have potential for use in detecting food fraud. © 2022 Society of Chemical Industry.

Abstract
A new methodology for immobilizing a triazolium salt onto polyethylene glycols (PEG) was developed. The immobilization is a two-step reaction, involving the tosylation of PEGs followed by a neat reaction between the PEG tosylates and the triazole. It is a high-yielding reaction conducted under mild conditions with a simple workup procedure. Hence, the salt 1-benzyl-4-phenyl-1H-1,2,3-triazolium iodide was immobilised onto PEGs of varying chain lengths (PEG300_8000) to yield various polymeric ionic liquids (PILs). All the PIL compounds were characterised by spectroscopic analysis and utilised as homogeneous metal-free organocatalysts for the transfer hydrogenation of ketones to alcohols in isopropanol as solvent and hydrogen source. The metal-free PIL catalysts showed activity for transforming acetophenone to 1-phenyl alcohol at up to 87% conversion. The representative PEG600 system was recycled three times with minimal loss in activity. The mechanism of a possible catalyst leaching was investigated using computational calculations. The results reveal that the promoter, isopropanol, also promotes the leaching of the triazole from the PEG backbone.

Abstract
Rabies is one of the oldest known zoonotic diseases. Rhabdovirus, an RNA virus belonging to the genus Lyssavirus and family Rhabdoviridae, causes rabies. Rabies diagnosis is challenging as the rabies virus remains confined to neurons after the initial animal bite. It largely remains immune-evasive until the infection reaches the central nervous system. The bottleneck in rabies diagnosis remains the non-availability of technical expertise and failure to collect an appropriate sample. The laboratory confirmation of rabies in both antemortem and postmortem samples is important. The samples were tested for anti-rabies antibodies using quantitative ELISA. In this report, two case studies are presented to demonstrate the suitability of ELISA for the intra vitam diagnosis of rabies using cerebrospinal fluid (CSF) as a diagnostic sample. The interpretation of serology results for both vaccinated and unvaccinated individuals has been discussed in detail, which has helped to confirm the antemortem diagnosis of rabies. In this report, we observed that ELISA can be a viable alternative for anti-rabies antibody detection in CSF and can be used as a viable alternative to more technically challenging tests, such as Rapid Fluorescent Focus Inhibition Test (RFFFIT) and Immunofluorescence Assays (IFA).

Abstract
Introduction: A range of assays have been developed to detect specific antileishmanial antibody, such as rK 39 immunochromatographic test (ICT), KE 16 ICT, ELISA test, and indirect immunofluorescent antibody test (IFAT), which play a crucial role in serological diagnosis of visceral leishmaniasis (VL). However, limited published reports are available on the utility of serological test (IFAT test/rk 39), smear examination, and culture in the diagnosis of VL and post-kala-azar dermal leishmaniasis (PKDL) in our country. Materials and Methods: We present utility of serological test (IFAT test/rK 39), smear examination for Leishmania donovani (LD) bodies, and culture in 2589 samples from 2294 VL/PKDL suspected patients (January 2009–December 2019) tested in Centre for Arboviral and Zoonotic diseases, National Centre for Disease Control, New Delhi, India, for laboratory diagnosis of VL/PKDL. Results: A total of 80/553 (14.4%) cases were confirmed of VL (74/522 cases by demonstration of LD bodies in bone marrow smear examination, 5/12 in splenic smear examination 1/19 by culture) and 4/21 (19.0%) cases were confirmed of PKDL (demonstration of LD bodies in slit skin smear examination. In our study 197/1368 (14.4%) cases were diagnosed positive by IFAT, 34/646 (5.2%) cases by rk 39 ICT for VL/PKDL by demonstration of specific antileishmanial antibodies. Conclusion: As the goal of elimination of VL as a public health problem is approaching, apart from serological tests such as rk 39 and IFAT, direct methods of detection such as (parasitic demonstration in BM smear, culture, and molecular tests) for Leishmania may play a crucial role for achieving a correct diagnosis and treatment. We also concluded that IFAT though not field-friendly, its optimal use as an adjunct test with BM smear in all stages of infections may be required. Further rk39 is a simple, reliable, noninvasive, and field-friendly test for diagnosis VL, especially in endemic areas.

This brief report documents an interesting and a rare case of 10 week old male puppy who suddenly showed a change in his behavior (irritable, agitated, anorexic, and refusing feeds), bitten six humans, and was laboratory-confirmed as died due to rabies (Rapid antigen test and reverse transcriptase polymerase chain reaction positive for rabies at the National Rabies Reference Laboratory, WHO collaborating Centre for Rabies Epidemiology, Centre for Arboviral and Zoonotic Diseases, National Centre for Disease Control, Delhi). All animal bite victims were timely provided postexposure prophylaxis for rabies who had shown sufficient seroconversion by IgG antirabies antibody using enzyme linked immunoassay (ELISA) and have been reported healthy. This case report reinforces the role of veterinarians/primary care physicians for strong suspicion of rabies encephalitis in puppies with behavioral or neurologic abnormalities and timely/appropriate rabies immunization of the animal bite victims. Shreds of evidence also focus that rabies in puppies younger than 3 months of age is grave and the risk of human beings contracting rabies from young puppies is of public health importance because of fatal consequences. Continuing medical education for primary care physicians and veterinarians, and outreach community public awareness campaigns should be regularly done to promote knowledge of pre-exposure/post-exposure prophylaxis, preventive measures, and animal bite management.

Abstract
A large quantity of trace metals has been continuously polluting the environment as a result of increasing urbanization and industrial processes. In 2016-2017, the metal (Cd, Cu, Cr, Ni, Pb, and Zn) levels were determined in fecal pellets of Blue Rock Pigeon (Columba livia) at Bais Godam (industrial location) in Jaipur and Chittora (rural location) in Rajasthan, India. Fecal pellets in industrial regions which are under higher anthropogenic influence exhibited higher metal concentrations when compared with the fecal pellets of the same species in rural area which have minimal anthropogenic input, with statistically significant industrial-rural differences in the metal concentrations except for Ni. Results obtained in this study, as well as the comparison with literature data, indicated that concentrations of Cr and Cu were high in fecal pellets of Blue Rock Pigeon in the industrial region of the present study. Furthermore, many significant correlations were also observed between metal levels in the industrial region which could be attributed to a similar source. Moreover, contamination levels of pigeon excrement serve as one of the most compelling indicators in terrestrial systems for the monitoring of metal pollution levels.

Abstract
BACKGROUND This perspective documents the historical aspects of outbreaks of plague of last six decades, establishment of plague surveillance network in India with detailed insights about its activities and recent developments requiring focus on plague surveillance. Human plague was reported in Mulbagal area of Karnataka in 1966-67 only to re-emerge in the country in 1994 in Beed district (Maharashtra) and subsequently in Surat (Gujarat). Later Plague outbreak has been reported in the year 2002 with index case from Village Hatkoti, Shimla District in Himachal Pradesh. The last outbreak reported from India was in 2004 from Village Dangaud, Uttarkashi District in Uttarakhand followed by a period of quiescent since last 17 years. OBJECTIVES During the last few decades, at least three geographical areas experienced outbreaks of plague after silent period of 28 years. We recapitulate the response mechanism for containing outbreaks during the last three outbreaks of plague held in Maharashtra & Gujarat (1994), Himachal Pradesh (2002) and Uttarakhand (2004). We also document the Plague surveillance network of India and its activities which is a comprehensive surveillance system comprising of rodent, flea, canine and human surveillance whose foundation was started in 1964. The recent developments of last decade in terms of revised Human plague surveillance case definitions, Plague surveillance sites, vector control, novel diagnostics and vaccines in our country are also mentioned. CONCLUSION The thrust areas in control of plague outbreak are early detection and isolation of cases, timely effective antibiotic treatment, chemoprophylaxis to contacts, strengthening of surveillance system and massive IEC campaign in infected areas. Yersinia pestis (causative agent of Plague) also being an important bioterrorism agent, clinicians need to pay special attention to diagnose and microbiologists must be provided skilled training for laboratory confirmation to this pestilential disease for effective and timely management.

Abstract
Objective The aim of the present work was to propose and implement deep neural network (DNN)-based handheld diagnosis system for more accurate diagnosis and severity assessment of individuals with autism spectrum disorder (ASD). Methods Initially, the learning of the proposed system for ASD diagnosis was performed by implementing DNN algorithms such as a convolutional neural network (CNN) and long short-term memory (LSTM), and multilayer perceptron (MLP) with DSM-V based acquired dataset. The performance of the DNN algorithms was analyzed based on parameters viz. accuracy, loss, mean squared error (MSE), precision, recall, and area under the curve (AUC) during the training and validation process. Later, the optimum DNN algorithm, among the tested algorithms, was implemented on handheld diagnosis system (HDS) and the performance of HDS was analyzed. The stability of proposed DNN-based HDS was validated with the dataset group of 20 ASD and 20 typically developed (TD) individuals. Results It was observed during comparative analysis that LSTM resulted better in ASD diagnosis as compared to other artificial intelligence (AI) algorithms such as CNN and MLP since LSTM showed stabilized results achieving maximum accuracy in less consumption of epochs with minimum MSE and loss. Further, the LSTM based proposed HDS for ASD achieved optimum results with 100% accuracy in reference to DSM-V, which was validated statistically using a group of ASD and TD individuals. Conclusion The use of advanced AI algorithms could play an important role in the diagnosis of ASD in today's era. Since the proposed LSTM based HDS for ASD and determination of its severity provided accurate results with maximum accuracy with reference to DSM-V criteria, the proposed HDS could be the best alternative to the manual diagnosis system for diagnosis of ASD.

Abstract
Hypercoagulability after trauma is a known entity. Following significant trauma, most guidelines advise anticoagulation treatment for venous thromboembolism (VTE) prophylaxis. VTE following minor trauma convoyed with arterial or systemic embolization dictate the need to search for uncommon source of thromboembolic complications. This is a report of an unusual case of pulmonary and systemic emboli complicated by splenic abscess following minor trauma in a patient with Diabetes Mellitus as the first presentation of patent foramen ovale (PFO).

Abstract
BACKGROUND Involving medical undergraduate students in patients' health education will not only help in improving students' learning as well as professional and communication skills but also plays an important role in achieving better health outcome of patients. The aim of the study was to assess the impact of students led educational intervention regarding tuberculosis (TB) on their learning and on the patients' knowledge and attitude towards the disease. MATERIALS AND METHODS One hundred medical undergraduates were included in the study. An integrated lecture on TB was given to all participants followed by preintervention test on TB. One group was then subjected to interactive traditional lecture. Whereas the videos reflecting the experiences of TB patients were shown to the other group and was given an assignment to prepare educational leaflets for TB patients followed by postintervention test for both groups. The patients' satisfaction level with the information given via educational leaflet and the overall perceived benefits of this activity by the students were assessed. Data analysis done using SPSS version 23.0. Independent and paired t-test were used to calculate difference of means for quantitative variables. RESULTS Two groups were comparable preintervention however postintervention there was significant improvement in knowledge in the study group (P0.000). Overall 74.2% of the patients were satisfied with the information provided through leaflets. Students' feedback highlighted that majority of the them felt benefitted from this activity. CONCLUSION It can be concluded that such type of educational interventions have dual benefits, i.e., learning for the students as well as providing health education to patients which in turn will improve their clinical outcome.

Abstract
CONTEXT Hospital-acquired infections (HAIs) are a global problem. One of the common causes of HAI is through the health-care workers, mainly because of failure to comply with the recommended infection control guidelines. AIMS The aim of our study was to educate and train the nurses regarding infection control practices and assess the impact of training and assess whether this training actually made any change in the incidence of catheter-associated urinary tract infection (CAUTI) and intravenous (IV) line-related infections. MATERIALS AND METHODS Baseline knowledge, attitude, and practices study of willingly participating 105 nurses regarding infection control was done. The incidence of CAUTI and IV line-related infection was calculated in the areas of their postings. They were trained via an educational module regarding infection control practices. We again assessed the incidence of CAUTI and IV line-related infections in the same areas 2 months after training. Data analysis was done using SPSS version 20.0. Student's t-test was used to analyze the difference in the prevalence of CAUTI and IV line-associated HAIs pre intervention and post intervention. RESULTS There was reduction in the incidence of IV line-related infection, though it was not significant (P 0.15) and no change in the incidence of CAUTI after intervention. CONCLUSION Single educational module though improved nurses' knowledge and attitude regarding infection control but failed to result in significant improvement in practices and incidence of HAIs.

Abstract
Background and Aims: AA present prospective study was conducted to evaluate ocular changes occurring in patients undergoing spine surgery in the prone position. Material and Methods: A total of 44 patients of either sex, belonging to American society of Anaesthesiology I and II (aged 18-60 years) scheduled for elective spine surgery in prone position were enrolled in the study. Baseline IOP and MAP measurement were taken prior to induction. After induction of anaesthesia patients were intubated using flexo-metallic tube of appropriate size. IOP and MAP were recorded after induction of anaesthesia, following completion of surgery and immediately after turning the patient supine and 30 min following extubation. Blood loss and duration of surgery was also noted. The OPP was derived using the formula (OPP = MAP-IOP). Ophthalmic examination was also performed using direct and indirect ophthalmoscopy on the day prior to surgery and on first post-operative day to rule out anterior ischemic optic neuropathy (AION), posterior ischemic optic neuropathy (PION), and retinal ischemia. Results: Mean IOP significantly increased (18.91 ± 3.56 mm Hg) (P < 0.001) at the end of surgery as compared to baseline value 12.85 ± 3.07 mm Hg. As a result mean OPP significantly reduced (75.12 ± 16.45) (P = 0.0018) at the end of the procedure. Conclusion: In patient’s undergoing spine surgery in the prone position, careful patient positioning with no extrinsic pressure on the eyes, minimal surgical time and blood loss, and prevention of intraoperative hypotension, should be ensured to prevent the IOP rise and a reduction in OPP which can further prevent post-operative visual disturbance.

Abstract
An efficient and cost-effective technique, solution precipitation approach is adopted to synthesize five bright green luminescent terbium (III) complexes by employing the main β-hydroxy ketone ligand, 2-hydroxy-4-ethoxyacetophenone, and ancillary ligands like bathophenanthroline, 5,6-dimethyl-1,10-phenanthroline, 1,10-phenanthroline, and 2,2-bipyridyl. The elemental compositions and binding mode of ligand to terbium (III) ion can be validated by using energy dispersive X-ray analysis, elemental analysis, Fourier transform infrared, and proton nuclear magnetic resonance spectroscopy. The complexes are thermally stable up to 158°C and possess the cubic shaped particles as confirmed by thermogravimetric analysis and scanning electron microscopic study, respectively. The band-gap energy (3.02-2.92 eV) of complexes is reckoned through diffuse reflectance spectra, which tailors them as potential candidates in the field of military radars. The photoluminescence studies unveil that the complexes exhibit the bright green luminescence corresponding to 5 D4 → 7 F5 transition of Tb3+ ion (548 nm) under the excitation wavelength of 395 or 397 nm. The Commission International de I'Eclairage chromaticity coordinates (x, y) and color purity substantiates the green emission of complexes. The energy transfer mechanism elucidates that the main ligand and ancillary ligands sensitize Tb3+ ion, which in turn enhances the luminescence efficiency of the emissive layer of white organic light emitting diodes. The results reveal that the complexes are considered as good contenders in the field of display devices and laser technology. Lastly, in vitro antimicrobial and antioxidant activity proclaim the potent antimicrobial and antioxidant actions of complexes via tube dilution and 2, 2-diphenyl-1-picrylhydrazyl assays, respectively.

Abstract
The study was conducted to monitor concentration of six toxic metals in faecal pellets of blue rock pigeon from six industrial areas of Jaipur, i.e. Jhotwara, Malviya, Mansarover, Sitapura, Vishwakarma industrial areas and Sanganer industries, by using atomic absorption spectrophotometer. At the same time, trace metals were also analysed for a reference area so that a comparative impact of the metal pollution from the industries could be figured out. From the data obtained, the highest Cd, Cu, Ni, Pb and Zn concentrations were found in the faecal pellets from Sitapura industrial area (1.12 ± 0.60 μg/g; 128.9 ± 11.10 μg/g; 17 ± 2.87 μg/g; 79.6 ± 42.69 μg/g; 2250 ± 1390.16 μg/g) and the highest Cr (18.6 ± 3.65 μg/g) from Jhotwara industrial area. However, industrial environment has high deposition of studied trace metals (except Ni for Sanganer industries) as compared with reference area. The concentration of Cd was below the detectable level in faecal pellets from reference area. The trend of trace metals from Malviya, Sitapura, Jhotwara and reference areas was noticed as Zn > Cu > Pb > Cr > Ni > Cd and almost same for Sanganer industries and Mansarover industrial area as Zn > Cu > Cr > Pb > Ni > Cd. The excretion of heavy metals in fa1ecal pellets from Vishwakarma industrial area was noticed as Zn > Cr > Cu > Pb > Ni > Cd. Further levels of metals were varied significantly among different industrial areas, P ≤ 0.05, as well as between industrial areas and reference area. The observed high concentration of different heavy metals in faecal pellets of bird species shows their exposure to metal contamination which is warning to spiked environmental pollution.

Abstract
Different properties of grass pea (Lathyrus sativus L.) flour passed through 60, 72, 85, 100, 150 and 200 mesh sieves and in the size range of 249-74 μm were studied. The protein content reduced while fat content improved significantly with diminution in particle size. Flowability, capacities to absorb water and form foam as well as stability of foam decreased while increase in swelling capacity, swelling index, oil absorption capacity was observed with decrease in flour particle size. Bimodal curve patterns were obtained for coarse flour samples of 249 μm and 211 μm using light scattering analysis. Scanning electron microscopy analysis revealed that starch granules were of variable shape embedded in protein and fibre matrix. The flour with fine particle size exhibited greater values for peak, final, break down and set back viscosities and the dough from fine particles showed highest values for storage modulus (G′), loss modulus (G″),|G∗| and |η∗|.

Abstract
INTRODUCTION India has the highest number of TB (27%) and MDR/RR-TB (24%) cases among the notified TB patients. Xpert MTB/ RIF assay is a fully automated cartridge-based real-time PCR to detect MTB and resistance to rifampicin within two hours using three specific primers and five unique molecular probes to target the rpoB gene. This study was done to detect RR-TB cases and frequency of missing probes, which target mutations in rpoB gene, in the different groups of study population in Sirmaur district of Himachal Pradesh. METHODS All, pulmonary and extrapulmonary specimens, were processed for AFB microscopy and Xpert MTB/RIF assay to diagnose TB and RR-TB. RESULTS Xpert detected MTBC in 721 patients. Using AFB microscopy, only 284 samples were positive. Of these MTB positive patients, 671 had pulmonary TB and 50 were EPTB cases. Resistance to RIF was detected in 31 (4.29%) cases of which resistance in presumptive tuberculosis group and presumptive drug resistant tuberculosis was 1.51% and 9.30% respectively. Twentyeight (4.17%) PTB cases and three (6%) EP-TB cases were resistant to RIF. The frequency of probe E was highest (77.41%) and mutation combination of probes C and D and E and D was 3.22%. CONCLUSION Drug resistance in the MTBC is mainly conferred through point mutations in specific gene targets in the bacterial genome. Molecular assays like Genexpert gives rapid diagnosis and Rifampicin resistance. This study helps to provide baseline data of mutations with in the 81 bp of rpoB gene and stresses the need to further evaluate the mutation patterns in this part of the country.

Abstract
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an autosomal dominant small-vessel disease caused by mutations of the NOTCH3 gene. It typically presents with migraine, recurrent brain ischaemia, and cognitive disorders. Seizures rarely present as the initial manifestation, with non-convulsive status epilepticus being even less frequent. We present a series of 3 related patients with this arteriopathy, 2 of whom presented status epilepticus as a manifestation of the disease.

Abstract
ObjectiveFor more than half a century, surgeons who managed vascular injuries were guided by a 6-hour maximum ischaemic time dogma in their decision to proceed with vascular reconstruction or not. Contemporary large animal survival model experiments aimed at redefining the critical ischaemic time threshold concluded this to be less than 5 hours. Our clinical experience from recent combat vascular trauma contradicts this dogma with limb salvage following vascular reconstruction with an average ischaemic time of 6 hours.MethodsDuring an 8-month period of the Sri Lankan Civil War, all patients with penetrating extremity vascular injuries were prospectively recorded by a single surgeon and retrospectively analysed. A total of 76 arterial injuries was analysed for demography, injury anatomy and physiology, treatment and outcomes. Subsequent statistical analysis was performed to evaluate the impact of independent variables to include; injury anatomy, concomitant venous, skeletal trauma, shock at presentation and time delay from injury to reconstruction.ResultsIn this study, the 76 extremity arterial injuries had a median ischaemic time of 290 (IQR 225–375) min. Segmental arterial injury (p=0.02), skeletal trauma (p=0.05) and fasciotomy (p=0.03) were found to have a stronger correlation to subsequent amputation than ischaemic time.ConclusionsMultiple factors affect limb viability following compromised distal circulation and our data show a trend towards various subsets of limbs that are more vulnerable due to inherent or acquired paucity of collateral circulation. Early identification and prioritisation of these limbs could achieve functional limb salvage if recognised. Further prospective research should look into the clinical, biochemical and morphological markers to facilitate selection and prioritisation of limb revascularisation.

Abstract
Background: India first detected SARS-CoV-2, causal agent of COVID-19 in late January 2020, imported from Wuhan, China. From March 2020 onwards, the importation of cases from countries in the rest of the world followed by seeding of local transmission triggered further outbreaks in India. Methods: We used ARTIC protocol-based tiling amplicon sequencing of SARS-CoV-2 (n=104) from different states of India using a combination of MinION and MinIT sequencing from Oxford Nanopore Technology to understand how introduction and local transmission occurred. Results: The analyses revealed multiple introductions of SARS-CoV-2 genomes, including the A2a cluster from Europe and the USA, A3 cluster from Middle East and A4 cluster (haplotype redefined) from Southeast Asia (Indonesia, Thailand and Malaysia) and Central Asia (Kyrgyzstan). The local transmission and persistence of genomes A4, A2a and A3 was also observed in the studied locations. The most prevalent genomes with patterns of variance (confined in a cluster) remain unclassified, and are here proposed as A4-clade based on its divergence within the A cluster. Conclusions: The viral haplotypes may link their persistence to geo-climatic conditions and host response. Multipronged strategies including molecular surveillance based on real-time viral genomic data is of paramount importance for a timely management of the pandemic.

Abstract
Ethyl 3, 4, 5-trihydroxybenzoate (GAE) is a major bioactive constituent of Hippophae Rhamnoides L. leaves and extract prepared from H. rhamnoides leaves exhibited radioprotective and pharmacological activity. Radiomodifying properties of polyphenol compounds through free radical neutralizing have been reported earlier. However, to date pharmacokinetic (PK) and biodistribution of polyphenol compounds post 60Co-γ-irradiation (5 Gy) exposure have not been studied yet. The study aims to investigate the radio modifying and inflammatory action, PK and biodistribution of GAE at a radioprotective dose and changes, if any, induced after irradiation. Male C 57 BL/6 mice (28-30 g) were administered GAE (200 mg/kg b.wt) orally 15 minutes post to irradiation. Mice were sacrificed at 15, 30 min, 1,2,4,8 and 24 h. PK and biodistribution of GAE in plasma and tissues were studied. The radiomodifying potential was assessed in terms of mitigating NF-kB activity and SGOT, SGPT, urea and creatinine levels in liver and kidney post irradiation. Our study suggested the potential use of GAE as radiomodifying agent inhibits NF-kB expression and maintains the SGOT 24.10 ± 2.4, SGPT 36.01 ± 6.1 U/l, urea18.16 ± 0.003, and creatinine 1.05 ± 0.04 mg/dL upto 8 h in comparison to irradiated mice. Moreover, in biodistribution studies, showed that GAE crosses the blood-brain barrier and is found in brain tissue. Plasma level of GAE peaked at about 15 min, with Cmax 4390.85 ± 285.20 in GAE and in 3391.78 ± 78.13 ng/mL in radiation + GAE-treated animals, Biodistribution resulted in the highest concentration to be found in liver and kidney. These radiomodifying and pharmacokinetic result may be useful for study of the bioactive mechanism associated with radiation injury and to develop a potent formulation of GAE for clinical application.

Abstract
OBJECTIVE Today, most of the individuals with Autism Spectrum Disorders (ASD) have atypical sensory behaviors. The main aim of this study is to propose an assistive intervention for supporting the overloaded sensory responses in hypersensitive individuals with ASD. METHODS The vision, auditory, smell, and physical balance related multi-sensors based hardware prototype, namely Assistive Companion for Hypersensitive Individuals (ACHI) has been designed for individuals with ASD. The proposed ACHI prototype is an assistive-technology based companion for hypersensitive individuals with ASD which is able to 'fetch/detect the sensory information using electronic sensors', 'making the decision using fuzzy logic on the basis of fetched sensory information' and then, 'transmit the generated information over the internet through the Internet of Things (IoT)', and also able for 'generating alerts to caregivers'. The proposed design is also capable of providing audio & video feedback to calm down individuals with ASD. RESULTS After testing, it is observed that 93% percent of the caregivers rated the proposed ACHI intervention on the scale of above average. The remarkable reduction in hyperactive states related triggering incidents in ASD has been found with the use of ACHI. CONCLUSION The present work and the proposed prototype can identify and control the sensory overload triggers in ASD and it can guide the caregiver or clinicians to optimize the responsible surrounding causes of explosive behavior in ASD and would help the individuals with ASD to become calm.

Abstract
OBJECTIVES Self-collected vaginal swabs can facilitate diagnosis of vaginal discharge (VD) in resource-limited settings, provided reliability of the method is established. The aim of this study was to evaluate the concordance between self-collected and physician-collected vaginal swabs for aetiological diagnosis of VD and to determine the prevalence of bacterial vaginosis (BV), vulvovaginal candidiasis (VVC) and trichomonas vaginitis (TV). METHODS A total of 550 females (median age: 32 years; range: 18-45 years) attending two sexually transmitted infection/reproductive tract infection (STI/RTI) clinics with VD from January 2015 to May 2016 were included in the study after obtaining written informed consent. Swabs were self-collected by patients after instructions and subsequently by a physician under speculum examination. Samples were processed for standard bedside tests, Gram staining, wet mount and culture (gold standard) according to the national guidelines. Concordance between the two methods was determined by the Cohen's kappa value. RESULTS BV, VVC and TV were diagnosed in 79 (14.4%), 144 (26.2%) and 3 (0.5%) patients, respectively. VVC coexisted with BV in 58 (10.5%) patients. There was no coinfection of TV with BV or VVC. Candida albicans was isolated in 84 (58.3%) VVC cases. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of self-collected swabs for diagnosing BV was 91.1%, 100%, 100% and 98.5%, respectively, while for the C. albicans VVC and TV, sensitivity, specificity, PPV and NPV all were 100% as compared with physician-collected swabs. Highly concordant results were obtained between two methods by the Kappa values of 0.95 (BV), 0.99 (VVC) and 1.0 (TV). CONCLUSION The comparative performance of self-collected and physician-collected vaginal swabs establishes self-collection of samples for BV, VVC and TV as a viable alternative tool in the management of STIs/RTIs, especially in peripheral and resource-constrained settings. This would be effective in implementing the diagnostic approaches for STIs/RTIs in community-based surveillance studies at national or regional level and therefore strengthening the National STI/RTI Control Programme.

Abstract
The thermal spike model (TSM), a widely accepted mechanism of swift heavy ion (SHI)-matter interactions, provides explanation for various SHI induced effects, including mixing across interfaces. We assess the validity of the model via tuning the electron-phonon coupling strength (G) by taking a series Pd1-xNix of a completely solid soluble binary, and then observing Pd1-xNix/Si interface mixing induced by a combination of 100 MeV Au ion irradiation and 4 keV Ar ion sputtering. If the TSM truly describes the SHI-matter interaction mechanism, any non-linearity in x-variation of G must also result in a similar non-linearity in the x-dependence of mixing. Experimentally, the extent of mixing has been parametrized by the irradiation induced change Δσ2 in variances of Pd and Ni depth profiles derived from XPS. Computationally, G determined using density functional theory has been used to solve the equations appropriate to the TSM, and then an equivalent quantity L2, proportional to Δσ2, has been calculated. Both Δσ2(x) and L2(x) show non-linearities, albeit in slightly dissimilar ways, leading to a conjecture that the present work at least does not invalidate the TSM.

Abstract
Quality protein maize (QPM) is nutritionally improved maize which has twice the amount of lysine and tryptophan than normal maize. The present study evaluated the effect of different proteins namely egg white proteins (EWP), casein, whey protein isolate, soy protein isolate (SPI) on characteristics of gluten free QPM based muffins. QPM muffins without any added protein served as control and muffins prepared using wheat and EWP served as reference. Effect of addition of different proteins on pasting properties revealed that the thermal stability of QPM flour increased as indicated by decrease in breakdown viscosity. The effect of added proteins on QPM muffin-making properties was evaluated for rheology of batter and physicochemical, texture, color and sensory characteristics of muffins. Dynamic rheology showed that storage modulus (G') and loss modulus (G″) of batter with SPI was the highest while batter with EWP showed lowest value. QPM-EWP muffins were softer, chewy and springier and had more specific volume than control muffins and were comparable to reference muffins. Inclusion of all proteins increased L* values (lightness) and decreased a* (redness/greenness) and b* (yellow/blueness) values of QPM based muffins. Sensory analysis revealed that gluten free QPM muffin prepared from EWP were acceptable with a sensory score of 7.97 which was comparable to reference muffins (8.03).

Abstract
Background Post kala azar dermal leishmaniasis (PKDL) is a neglected dermatosis that develops as a sequel to kala azar after apparent complete treatment. Being a non life threatening condition, patients often delay treatment thereby maintaining a reservoir of infection. The diagnosis of PKDL rests on the demonstration of the parasite in tissue smears, immune diagnosis by detection of parasite antigen or antibody in blood, or detection and quantitation of parasite DNA in tissue specimens. Sophisticated molecular tests are not only expensive but also need skilled hands and expensive equipment. To be useful, diagnostic methods must be accurate, simple and affordable for the population for which they are intended. Aims This study was designed to assess functionality and operational feasibility of slit-skin smear examination. Methods Sensitivity and specificity was evaluated by performing slit-skin smear and histo-pathological examination in 46 PKDL patients and the results were compared with the parasite load in both the slit aspirate and tissue biopsy specimens by performing quantitative Real-time PCR (Q-PCR). Results The slit-skin smear examination was more sensitive than tissue biopsy microscopy. The parasite loads significantly differed among various types of clinical lesions (P < 0.05). The threshold of parasite load for detection by SSS microscopy was 4 parasites/μl in slit aspirate and 60 parasites/μg tissue DNA in tissue biopsy while that for tissue microscopy was 63 parasites/μl and 502 parasites/μg tissue DNA respectively. As detection of Leishmania donovani bodies may be challenging in inexperienced hands, the microscopic structure of these has been detailed along with a comprehensive discussion of pre analytical, analytical and post analytical variables affecting its identification. To facilitate the diagnosis of PKDL, some scenarios have been suggested taking into consideration the clinical, epidemiological, immunological and microscopic aspects. Conclusion Such evidence based medicine helps minimize intuition, systematize clinical experience and provides a diagnostic rationale as sufficient grounds for a clinical decision.

Abstract
In the present study, thin films of single-phase CoSb3 were deposited onto Si(100) substrates via pulsed laser deposition (PLD) method using a polycrystalline target of CoSb3. These films were implanted by 120 keV Fe-ions with three different fluences: 1 × 1015, 2.5 × 1015 and 5 × 1015 ions per cm2. All films were characterised by X-ray diffraction (XRD), Raman spectroscopy, atomic force microscopy (AFM), Rutherford backscattering (RBS) spectrometry and X-ray absorption spectroscopy (XAS). XRD data revealed that the ion implantation decreased the crystalline nature of these films, which are recovered after the rapid thermal annealing process. The Seebeck coefficient S vary with the fluences in the temperature range of 300 K to 420 K, and is found to be highest (i.e., 254 μV K−1) at 420 K for the film implanted with 1 × 1015 ions per cm2. The high S and low resistivity lead to the highest power factor for the film implanted with 1 × 1015 ions per cm2 (i.e., 700 μW m−1 K−2) at 420 K. The changing of the sign of S from negative for the pristine film to positive for the Fe-implanted samples confirm that the Fe ions are electrically active and act as electron acceptors by replacing the Co atoms. XAS measurements confirm that the Fe ions occupied the Co site in the cubic frame of the skutterudite and exist in the 3+ oxidation state in this structure. The power factor for the Fe ion-implanted samples is greater than that of the pristine sample with a value of 700 mW m−1 K−2 at 420 K for the I1E15A sample.![]()
