Abstract
The objective of this current study is to establish a single method for potency and related proteins analysis of human insulin formulations using reverse-phase high performance liquid (RP-HPLC) chromatography technique which was validated and verified for the potency analysis in insulin formulations. Chromatographic separation was achieved using an octadecylsilane (C-18) stationary phase and a mobile phase composed of 55% (v/v) buffer (0.2 M sodium sulfate in water, {pH 2.3}) and 45% (v/v) acetonitrile. Detection was performed by UV detector at 214 nm with a flow rate of 1 ml/min and an injection volume of 20 µL, at 40°C. Currently there are separate methods available in Indian Pharmacopoeia for analysis of Potency and Related proteins in human insulin. We have validated a single method where quantitation of potency and related proteins can be performed in the same run. The method validation exhibited linearity over the concentration range of 0.08-4.5 mg/ml (r2=0.999) with limit of detection of 0.094 mg/ml The accuracy of the method was 99-102.8%. Thus, it is proposed that both potency and related proteins in insulin formulations can be precisely evaluated using a single run thus saving the time and cost for quality analysis of insulin preparations both at manufacturing and regulatory laboratories which in turn will increase the market availability of such standard quality insulin preparations for public health use.

Abstract
BACKGROUND Aggrephagy is a lysosome-dependent process that degrades misfolded protein condensates to maintain cancer cell homeostasis. Despite its importance in cellular protein quality control, the role of aggrephagy in glioma remains poorly understood. OBJECTIVE To investigate the expression of aggrephagy-related genes (ARGs) in glioma and in different cell types of gliomas and to develop an ARGs-based prognostic signature to predict the prognosis, tumor microenvironment, and immunotherapy response of gliomas. METHODS ARGs were identified by searching the Reactome database. We developed the ARGs-based prognostic signature (ARPS) using data from the Cancer Genome Atlas (TCGA, n = 669) by Lasso-Cox regression. We validated the robustness of the signature in clinical subgroups and CGGA cohorts (n = 970). Gene set enrichment analysis (GSEA) was used to identify the pathways enriched in ARPS subgroups. The correlations between ARGs and macrophages were also investigated at single cell level. RESULTS A total of 44 ARGs showed heterogeneous expression among different cell types of gliomas. Five ARGs (HSF1, DYNC1H1, DYNLL2, TUBB6, TUBA1C) were identified to develop ARPS, an independent prognostic factor. GSEA showed gene sets of patients with high-ARPS were mostly enriched in cell cycle, DNA replication, and immune-related pathways. High-ARPS subgroup had higher immune cell infiltration states, particularly macrophages, Treg cells, and neutrophils. APRS had positive association with tumor mutation burden (TMB) and immunotherapy response predictors. At the single cell level, we found ARGs correlated with macrophage development and identified ARGs-mediated macrophage subtypes with distinct communication characteristics with tumor cells. VIM+ macrophages were identified as pro-inflammatory and had higher interactions with malignant cells. CONCLUSION We identified a novel signature based on ARGs for predicting glioma prognosis, tumor microenvironment, and immunotherapy response. We highlight the ARGs-mediated macrophages in glioma exhibit classical features.

Abstract
Introduction Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed analgesics for controlling post-exodontia pain, administered by various routes. The transdermal route possesses the advantages of providing sustained release of the drug, being non-invasive, bypassing first-pass metabolism, and eliminating gastrointestinal adverse effects. This study compared the analgesic efficacy of diclofenac 200 mg and ketoprofen 30 mg transdermal patches for post-orthodontic exodontia pain. Materials and methods Thirty patients who underwent orthodontic bilateral maxillary and/or mandibular premolar extractions under local anaesthesia were included in the study. Each patient received single transdermal diclofenac 200 mg patch and single transdermal ketoprofen 30 mg patch on the outer, ipsilateral upper arm immediately post-extraction in the two appointments in random order. The pain score was recorded every second hourly for the first 24 hours postoperatively using a visual analog scale (VAS). The requirement of rescue analgesics at various time points and the total number of rescue analgesics taken in the first 24 hours postoperatively were noted. Any allergic reaction to the transdermal patches was also recorded. Results The analgesic efficacy of the two transdermal patches at any given time point in 24 hours by Mann-Whitney U test showed no statistically significant (p<0.05) difference. An overall intragroup statistically significant difference (p<0.05), by Wilcoxon matched pairs test, was found by comparison of VAS pain scores at different time points to that at 0-2 hours after application of transdermal ketoprofen and diclofenac patches, respectively. The mean maximum pain intensity was slightly lower for ketoprofen (2.33) than diclofenac (2.60) transdermal patch. Patients consumed the rescue analgesic within the first 12 hours postoperatively, with the mean value of the total number of rescue analgesics taken with ketoprofen transdermal patch (0.23) slightly lower than diclofenac transdermal patch (0.27) application. Conclusion Ketoprofen and diclofenac transdermal patches provide similar analgesia post orthodontic extraction. The patients required rescue analgesics only during the initial hours of the postoperative follow-up period.

Abstract
Objective To assess the main characteristics and result reporting of registered COVID-19 interventional trials of traditional Chinese medicine and traditional Indian medicine. Materials and methods We assessed design quality and result reporting of COVID-19 trials of traditional Chinese medicine (TCM) and traditional Indian medicine (TIM) registered before 10 February 2021, respectively, on Chinese Clinical Trial Registry (ChiCTR) and Clinical Trial Registry-India (CTRI). Comparison groups included registered COVID-19 trials of conventional medicine conducted in China (WMC), India (WMI), and in other countries (WMO). Cox regression analysis was used to assess the association between time from trial onset to result reporting and trial characteristics. Results The proportion of COVID-19 trials investigating traditional medicine was 33.7% (130/386) among trials registered on ChiCTR, and 58.6% (266/454) on CTRI. Planned sample sizes were mostly small in all COVID-19 trials (median 100, IQR: 50-200). The proportion of trials that were randomized was 75.4 and 64.8%, respectively, for the TCM and TIM trials. Blinding measures were used in 6.2% of the TCM trials, and 23.6% of the TIM trials. Cox regression analysis revealed that planned COVID-19 clinical trials of traditional medicine were less likely to have results reported than trials of conventional medicine (hazard ratio 0.713, 95% confidence interval: 0.541-0.939; p = 0.0162). Conclusion There were considerable between-country and within-country differences in design quality, target sample size, trial participants, and reporting of trial results. Registered COVID-19 clinical trials of traditional medicine were less likely to report results than trials of conventional medicine.

Abstract
We have recently undertaken a corporate strategy evaluation for a more accurate appraisal of the Ayurveda Practice Based Research Network's two-year outcomes. While many of our views and experiences may not be original to PBRN networks, we feel that for Integrative Ayurveda, our insights will be valuable to others who are constructing or reshaping Ayurveda practice in a shifting health care context.
Research that is contemporary, applicable, and amenable to integration into practice must be prioritized. Clinicians, academics, information technologists, and various scientists, as well as strategy implementation professionals, combining to establish a creative Hub, is a viable approach for reaching this objective in comparison to the original PBRN models. The creative Hub could assist academics in identifying significant research topics and meeting "critical" standards. Bridging the ends between practitioners, researchers, and clinicians may require novel partnerships and non-traditional funding sources in the future.

Abstract
PFAs (poly and perfluoroalkyl compounds) are hazardous and bioaccumulative chemicals that do not readily biodegrade or neutralize under normal environmental conditions. They have various industrial, commercial, domestic and defence applications. According to the Organization for Economic Co-operation and Development, there are around 4700 PFAs registered to date. They are present in every stream of life, and they are often emerging and are even difficult to be detected by the standard chemical methods. This review aims to focus on the sources of various PFAs and the toxicities they impose on the environment and especially on humankind. Drinking water, food packaging, industrial areas and commercial household products are the primary PFAs sources. Some of the well-known treatment methods for remediation of PFAs presented in the literature are activated carbon, filtration, reverse osmosis, nano filtration, oxidation processes etc. The crucial stage of handling the PFAs occurs in determining and analysing the type of PFA and its remedy. This paper provides a state-of-the-art review of determination & tools, and techniques for remediation of PFAs in the environment. Improving new treatment methodologies that are economical and sustainable are essential for excluding the PFAs from the environment.

Abstract
In this article, we examine the effects of the COVID-19 pandemic on the labor conditions of domestic workers in the epicenter of the United States. We focus our analysis on the symbolic categorization of domestic work as "essential labor." While domestic workers are lauded as heroes in public discourse, we argue that this symbolic recognition does not extend to material remuneration. Instead, we find that labor conditions better fit their categorization as expendable essential workers, meaning those whose essential labor is magnified during the pandemic but whose work remains materially undervalued. Data used in this article draw from observations of more than 30 hours of virtual town hall meetings on the pandemic hosted by migrant domestic worker advocacy groups in Los Angeles and New York.

Abstract
Cellulose tris(3,5-dimethylphenylcarbamate) (CDMPC), known as one of the most versatile chiral selectors packed in columns for chiral chromatography, is electrospun for the first time. The electrospun nanofibers with a mean diameter of 329 nm form a self-standing nonwoven textile with a specific surface area of 5.6 m2/g. The textile is sandwiched between commercially available polytetrafluoroethylene membrane filters as a support material to fabricate a CDMPC membrane system for the chiral resolution of a racemic mixture, (R,S)-1-(1-naphthyl)ethanol. A vacuum filtration of the racemic mixture through the membrane system using a mixed solvent of n-hexane/2-propanol = 9/1 (v/v) enriches the S-enantiomer in the filtrate due to an enantioselective sorption of the R-enantiomer. The sorption capacity can be regenerated repeatedly via extractions of the adsorbed enantiomers from the membrane system after the filtrations. By repeating the vacuum filtration-extraction process for 15 cycles, the enantiomeric excess (e.e.) of the S-isomer in the filtrate increases up to 32.9%.

Abstract
Coronavirus disease 2019 (COVID-19) pandemic has caused significant impact on the health care system. As a consequence, diagnosis and treatment of vector borne diseases including dengue has been equally affected. Nepal is no exception to this, where COVID-19 cases is exponentially increased and all resources are concentrated on its prevention, control and management. Dengue, one of the major vector-borne diseases in Nepal, is apparently overlooked despite approaching the peak season of the disease. The aim of this paper is to describe the double burden of COVID-19 and dengue in Nepal, particularly highlighting the co-circulation and possible coinfections. This has posed higher risk of increased severity, more severe cases and deaths in Nepal. Moreover, potential misdiagnosis of these viral diseases may lead to delayed or, inappropriate treatment and poor allocation of resources.

Abstract
Dendritic cells (DCs), as antigen-presenting cells, can reportedly be infected withLeishmaniaparasites and hence provide a better option to trigger T-cell primary immune responses and immunological memory. We consistently primed DCs during culture with purified recombinant cytosolic tryparedoxin (rcTXN) and then evaluated the vaccine prospect of presentation of rcTXN against VL in BALB/c mice. We reported earlier the immunogenic properties of cTXN antigen derived fromL. donovani when anti-cTXN antibody was detected in the sera of kala-azar patients. It was observed that cTXN antigen, when used as an immunogen with murine DCs acting as a vehicle, was able to induce complete protection against VL in an infected group of immunized mice. This vaccination triggered splenic macrophages to produce more IL-12 and GM-CSF, and restricted IL-10 release to a minimum in an immunized group of infected animals. Concomitant changes in T-cell responses against cTXN antigen were also noticed, which increased the release of protective cytokine-like IFN-γ under the influence of NF-κβ in the indicated vaccinated group of animals. All cTXN-DCs-vaccinated BALB/c mice survived during the experimental period of 120 days. The results obtained in our study suggest that DCs primed with cTXN can be used as a vaccine prospect for the control of visceral leishmaniasis.

Abstract
BACKGROUND & OBJECTIVES In India, kala-azar surveillance is weak and no public-private partnership exists for disease containment. Estimate of disease burden is not reliably available and still cases are going to private providers for the treatment. The present study aimed to assess the magnitude of kala-azar cases actually detected and managed at private set-up and unreported to existing health management information system. METHODS Institution based cross-sectional prospective pilot study was conducted. List of facilities was created with the help of key informants. The information about incidence of kala-azar cases were captured on monthly basis from July 2010 to June 2011. Rapid diagnostic strip test (rk-39) or bone marrow/splenic puncture were applied as laboratory methods for the diagnosis of kala-azar. Descriptive statistics as well as chi-square test for comparison between proportions was conducted. RESULTS Overall availability of private practitioners (PPs) was 4.59/1,00,000 population and maximum PPs (46; 93.9%) were from qualified category. The median years of medical practice was 25 yr (inter quartile-range [18, 28]). Interestingly, only a small proportion (240; 19%) of cases was managed by PPs. Amongst the PPs, only low proportion (32; 18.2%) managed >2 cases per month. The mean number of kala-azar suspects and cases identified varied significantly between different PPs' professions with p <0.048 and p <0.032, respectively. A highly significant difference (p <0.0001) was observed for kala-azar case load between qualified and unqualified practitioners. A small proportion (38; 15.8%) of kala-azar cases was not present in the public health system record. INTERPRETATION & CONCLUSION Still sizeable proportions of cases are going to PPs and unrecorded into government surveillance system. A mechanism need to be devised to involve at least qualified PPs in order to reduce treatment delay and increase case detection in the region.

Abstract
Abstract
Background: With the increasing success of immune checkpoint blockades for cancer treatment, we increasingly need well-characterized preclinical models. Syngeneic mice models (with a fully competent immune system) have advantages that they are easily established and cost less, though they do not reflect genetic complexity of human tumors. We evaluated feasibility of syngeneic mice models of breast cancer by analyzing efficacy of immune checkpoint blockade and dynamic change of tumor immune microenvironment.
Methods: We used syngeneic mice model of JC, 4T1, and EMT6 cells, which are all murine triple negative breast cancer in BALB/c mice. At the time when subcutaneous tumors reach at 50˜100mm^3, each mice models were divided into 2 groups for treatment versus no-treatment control. In the treatment group, mice version of anti-PD-1 antibody was intraperitoneally injected (q 3 days, x 6). Anti-tumor efficacy was monitored by measuring tumor volume. 'Tumor response' was defined as a case with tumor volume less than that of control group by a standard error at a determined time point. Immune microenvironment was evaluated by measuring serum cytokines (IL-2, IL-6, IL-10, IFNγ, and TNFα) with legendplex and immune cells (CD3, CD4, CD8, CD56, and FOXP3) of peripheral blood with FACS before injection of PD-1 blockade, after 1st injection, and when euthanized. Tumor-infiltrating immune cells were evaluated with FACS, when euthanized.
Results: The tumor response rate to PD-1 blockade was highest in the 4T1 model (54.5%, 6/11) compared to JC model (40%, 4/10) or EMT6 model (36.4%, 4/11). Bleeding 3 times and tumor obtainment when euthanized in each mouse were feasible for profiling of cytokines and immune cells. Although before treatment with PD-1 blockade, CD3+T cells in peripheral blood were slightly lower in 4T1 model (18.3±8.1%) than JC model (24.6±4.7%) or EMT6 model (27.9±6.3%), after injection of one dose of PD-1 blockade, CD3+T cells increased 1.5 times in 4T1 model (18.3% to 27.3%), whereas those CD3+T cells decreased slightly in JC model and EMT6 model. Dynamic changes were not observed in other subsets of peripheral immune cells in all 3 models. Serum TNFα (with statistical significance) and IFNγ (with borderline significance) were higher in responders than in non-responders or no-treatment control.
Conclusions: Syngeneic mice models of breast cancer were feasible to investigate immune checkpoint blockades and monitor dynamic change of immune microenvironment. In this regard, such models may be used to evaluate immune checkpoint blockade-based combination therapy as well.

Abstract
Topology, geometry, and gauge fields play key roles in quantum physics as exemplified by fundamental phenomena such as the Aharonov-Bohm effect, the integer quantum Hall effect, the spin Hall, and topological insulators. The concept of topological protection has also become a salient ingredient in many schemes for quantum information processing and fault-tolerant quantum computation. The physical properties of such systems crucially depend on the symmetry group of the underlying holonomy. Here, we study a laser-cooled gas of strontium atoms coupled to laser fields through a four-level resonant tripod scheme. By cycling the relative phases of the tripod beams, we realize non-Abelian SU(2) geometrical transformations acting on the dark states of the system and demonstrate their non-Abelian character. We also reveal how the gauge field imprinted on the atoms impact their internal state dynamics. It leads to a thermometry method based on the interferometric displacement of atoms in the tripod beams.

Abstract
The shift of macrophage and T-cell repertoires towards proinflammatory cytokine signalling ensures the generation of host-protective machinery that is otherwise compromised in cases of the intracellular Leishmania parasite. Different groups have attempted to restore host protective immunity. These vaccine candidates showed good responses and protective effects in murine models, but they generally failed during human trials. In the present study, we evaluated the effect of 97 kDa recombinant nucleoporin-93 of Leishmania donovani (rLd-NUP93) on mononuclear cells in healthy and treated visceral leishmaniasis (VL) patients and on THP-1 cell lines. rLd-NUP93 stimulation increased the expression of the early lymphocyte activation marker CD69 on CD4+ and CD8+ T cells. The expression of the host protective pro-inflammatory cytokines IFN-γ, IL-12 and TNF-α was increased, with a corresponding down-regulation of IL-10 and TGF-β upon rLd-NUP93 stimulation. This immune polarization resulted in the up-regulation of NF-κB p50 with scant expression of SMAD-4. Augmenting lymphocyte proliferation upon priming with rLd-NUP93 ensured its potential for activation and generation of strong T-cell mediated immune responses. This stimulation extended the leishmanicidal activity of macrophages by releasing high amounts of reactive oxygen species (ROS). Further, the leishmanicidal activity of macrophages was intensified by the elevated production of nitric oxide (NO). The fact that this antigen was earlier reported in circulating immune complexes of VL patients highlights its antigenic importance. In addition, in silico analysis suggested the presence of MHC class I and II-restricted epitopes that proficiently trigger CD8+ and CD4+ T-cells, respectively. This study reported that rLd-NUP93 was an effective immunoprophylactic agent that can be explored in future vaccine design.

Abstract
We recently discovered that the orphan G-protein-coupled receptor (GPR) 61 colocalized with GnRH receptors (GnRHRs) on the surface of most of bovine gonadotrophs. A recent study suggested that ethanolamine plasmalogen (PI) is a ligand for GPR61 in mouse neuroblastoma. Therefore, this study evaluated the hypothesis that PI alters LH and FSH secretion from cultured bovine anterior pituitary (AP) cells. We prepared bovine AP cells from postpubertal heifers (26 mo old) and cultured the cells for 3.5 d. We treated the cells with increasing concentrations (0, 5, 50, 500, 5,000, 50,000, or 500,000 pg/mL) of phosphoethanolamine PI (PEPI) extracted from the bovine brain, or l-α-lysophosphatidylethanolamine PI (LEPI) extracted from the bovine brain, for 5 min before either no treatment or GnRH stimulation. The medium samples were harvested 2 h after culture for LH and FSH assays. Phosphoethanolamine PI (50-500 pg/mL) stimulated (P < 0.05) the basal secretion of FSH but not LH. Phosphoethanolamine PI at 50 pg/mL also enhanced (P < 0.05) GnRH-induced FSH secretion. However, higher doses (500-500,000 pg/mL) of PEPI suppressed GnRH-induced FSH secretion. Moreover, 50 to 500,000 pg/mL PEPI suppressed GnRH-induced LH secretion. None of the tested concentrations of LEPI showed any effect on basal or GnRH-induced LH or FSH secretion. Pretreatment with Sma and Mad pathway inhibitors suppressed FSH secretion induced by PEPI, whereas an extracellular signal-regulated kinase pathway inhibitor blocked the PEPI-induced suppression of GnRH-stimulated LH secretion. Therefore, PEPI, but not LEPI, extracted from the bovine brain, alters FSH and LH secretion from cultured AP cells. Further studies are required to decide whether PEPI binds to GPR61 and whether PEPI plays an important role in the control of gonadotropin secretion from gonadotrophs.

Abstract
Basal cell carcinoma (BCC) and squamous cell carcinoma are the most common type of nonmelanoma skin cancers (NMSCs). Bowen's disease (BD), a premalignant condition, has a marginal potential (3-5%) to progress to invasive carcinoma. We report here a rarest of a rare case of multiple pigmented BD with overlying squamous cell cancer along with a giant neglected BCC on the scalp of a 76-year-old man. The occurrence of multiple BD and NMSC in a single patient compelled us to explore the following hypothesis: (1) The multiple precancerous and cancerous lesions can be due to common etiopathogenesis. Chronic ultraviolet exposure, immunosupresssion, human papillomavirus infection, dietary factors, and environmental factors including arsenic exposure were probed in to. (2) There is evolution of precancerous lesions into a different type of cancers in different time frame. (3) The new cancerous lesions are subsequent cancers that developed after neglected untreated primary cancer.

Abstract
BACKGROUND Natalizumab (NTZ), a monoclonal antibody to human α4β1/β7 integrin, is an effective therapy for multiple sclerosis (MS), albeit associated with progressive multifocal leukoencephalopathy (PML). Clinicians have been extending the dose of infusions with a hypothesis of reducing PML risk. The aim of the study is to evaluate the clinical consequences of reducing NTZ frequency of infusion up to 8 weeks 5 days. METHODS A retrospective chart review in 9 MS centres was performed in order to identify patients treated with extended interval dosing (EID) regimens of NTZ. Patients were stratified into 3 groups based on EID NTZ treatment schedule in individual centres: early extended dosing (EED; n=249) every 4 weeks 3 days to 6 weeks 6 days; late extended dosing (LED; n=274) every 7 weeks to 8 weeks 5 days; variable extended dosing (n=382) alternating between EED and LED. These groups were compared with patients on standard interval dosing (SID; n=1093) every 4 weeks. RESULTS 17% of patients on SID had new T2 lesions compared with 14% in EID (p=0.02); 7% of patients had enhancing T1 lesions in SID compared with 9% in EID (p=0.08); annualised relapse rate was 0.14 in the SID group, and 0.09 in the EID group. No evidence of clinical or radiographic disease activity was observed in 62% of SID and 61% of EID patients (p=0.83). No cases of PML were observed in EID group compared with 4 cases in SID cohort. CONCLUSIONS Dosing intervals up to 8 weeks 5 days did not diminish effectiveness of NTZ therapy. Further monitoring is ongoing to evaluate if the risk of PML is reduced in patients on EID.

Abstract
The objective of this study was to describe SymptoMScreen, an in-house developed tool for rapid assessment of MS symptom severity in routine clinical practice, and to validate SymptoMScreen against Performance Scales (PS). MS patients typically experience symptoms in many neurologic domains. A tool that would enable MS patients to efficiently relay their symptom severity across multiple domains to the healthcare providers could lead to improved symptom management. We developed "SymptoMScreen," a battery of 7-point Likert scales for 12 distinct domains commonly affected by MS: mobility, dexterity, body pain, sensation, bladder function, fatigue, vision, dizziness, cognition, depression, and anxiety. We administered SymptoMScreen and PS scales to consecutive MS patients at a specialty MS Care Center. We assessed the criterion and construct validity of SymptoMScreen by calculating Spearmen rank correlations between the SymptoMScreen composite score and PS composite score, and between SymptoMScreen subscale and the respective PS subscale scores, where applicable. A total of 410 patients with MS (age 46.6 ± 12.9 years; 74% female; mean disease duration 12.2 ± 8.7 years) completed the SymptoMScreen and PSs during their clinic visit. Composite SymptoMScreen score correlated strongly with combined PS score (r = 0.88, p < 0.0001). SymptoMScreen sub scores correlated strongly with the criterion measures of the respective PS (r = 0.69-0.87, p < 0.0001). Test-retest reliability of SymptoMScreen and its subscales was excellent (r = 0.71-0.94, p < .0001). SymptoMScreen is a single-page battery of Likert scales that assesses symptom impact in 12 domains commonly affected in MS. It has excellent criterion and construct validity. SymptoMScreen is patient and clinician friendly, takes approximately one minute to complete, and can help better document, understand, and manage patients' symptoms in routine clinical practice. SymptoMScreen is freely available to clinicians and researchers.

Abstract
BACKGROUND AND OBJECTIVES Chronic obstructive pulmonary disease (COPD) is a major health problem in India and constitutes an important cause of mortality and morbidity. A cross-sectional study was undertaken to assess health-related quality of life (HRQL) and its determinants in patients with COPD from India. MATERIALS AND METHODS A total of 126 patients (73.81% male) were enrolled using convenient sampling prospectively in this cross-sectional study. Eligible patients were assessed for socioeconomic status, anthropometric measures, COPD severity, dyspnea and health status using the Hindi version of St George's Respiratory Questionnaire (SGRQ). Linear regression model was used to examine the association between risk factors and HRQL score (a higher score indicating poorer HRQL), adjusting for age and sex. RESULTS The mean total score for SGRQ in the patients was 52.66 ± 12.89, indicating a marked impairment of HRQL. Impairment was associated with the severity of airway obstruction, but within each Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage, the variation (SD) was wide [stage I: 47.8 ± 12.3 (n = 14); stage II: 49.28 ± 11.69 (n = 47); stage III: 53.47 ± 11.69 (n = 44); stage IV: 61.75 ± 14.14 (n = 21)]. A regression analysis showed that body mass index, forced expiratory volume in 1 s (FEV 1 ), dyspnea grade, and depression were associated with poor HRQL. CONCLUSION HRQL of COPD patients was significantly impaired across stages. Marked impairment of HRQL was found even in patients with mild disease.

Abstract
We investigate the transient coherent transmission of light through an optically thick cold strontium gas. We observe a coherent superflash just after an abrupt probe extinction, with peak intensity more than three times the incident one. We show that this coherent superflash is a direct signature of the cooperative forward emission of the atoms. By engineering fast transient phenomena on the incident field, we give a clear and simple picture of the physical mechanisms at play.

Abstract
II-VI semiconductor nanocrystals have attracted much attention due to their size dependent properties ranging from electronic to biological regimes. Herein results of ZnS and CdS ADXRD (Angle dispersive X-ray diffraction) data, recorded in transmission mode, on BL-11 Beamline of INDUS Synchrotron are reported. Semiconductors obtained using wet chemical co-precipitation method, were kept for a few hours in the deep freezer. The wavelength of x-rays was 0.04666 nm (27 keV). A MAR 3450 image plate was used as detector. Sample to detector distance was 185.9178 mm. XRD data were extracted using fit2d. ADXRD pattern was recorded in transmission mode. The fityk program was used to fit pseudo Voigt A function to the ADXRD data to get the half width at half maximum (HWHM) of the peaks. These HWHMs values as well as the Scherrer formula yielded the particle sizes. The Neilson-Riley method was used to refine the lattice parameters. Results of the ADXRD data analyses for both ZnS and CdS are given below:The Particle size (nm), Bravais Lattice, Lattice parameter (nm) and Eg (eV) [UV abs spectra] for ZnS are 2.81, F¯43m, 0.5371 and 3.82 respectively while for CdS these values are 3.03, F¯43m, 0.580, 2.59 respectively. From these data the metal-S and Metal-Metal distances were calculated and were found out for ZnS to be 0.2326 nm and 0.3798 nm while for CdS these distances are 0.251 nm and 0.41 nm respectively. These data match well with the literature/1/. Particle sizes were in agreement with Brus's /2/ method.

Abstract
We report two cases, one male (33 years) and a female (14 years), that developed Post-Kala-azar Dermal Leishmaniasis (PKDL) after successful treatment for visceral leishmaniasis (VL) or Kala-azar with AmBisome, the lipid complex of Amphotericin B. Both cases presented with hypo-pigmented macular lesions all over the body. The patients responded well to AmBisome after treatment with three courses. This first ever case report from India indicates that possibly there is no effective drug for VL until date, which can prevent post-treatment development of PKDL.

Abstract
BACKGROUND Visceral leishmaniasis is potentially fatal protozoan diseases caused by Leishmania donovani. Nepal is an endemic region in which visceral leishmaniasis causes a major public health problem in the lowland areas that border the endemic areas of Bihar state in India. Accurate diagnosis to inform treatment is a first step in achieving the goal of visceral leishmaniasis elimination from South East Asian regions by 2020. OBJECTIVE The objective of the present study was to compare between the Microcopy and polymerase chain reaction for diagnosis of visceral leishmaniasis. METHODS In the present study, 236 bone marrow aspirations were collected from suspected visceral leishmaniasis patients in Janakpur Zonal Hospital, Dhanusa district, Terai region of Nepal in between 2003-2007. We evaluated bone marrow samples by microscopic examination with subsequent testing of the same sample by polymerase chain reaction and sequence analysis. RESULTS Giemsa's solution stained bone marrow slides stored for over five years were used for polymerase chain reaction amplification. The result showed that 71% were polymerase chain reaction positive and 56% were microscopic positive. Out of 104 microscopic negative bone marrow samples, 15% of samples were positive by polymerase chain reaction. CONCLUSION Polymerase chain reaction could make a very good option for diagnosis by using less or non-invasive material from visceral leishmaniasis patients in endemic areas of Nepal.

Abstract
Weeds are serious problem in dry direct seeded rice (DDSR). A field experiment was conducted during rainy seasons of 2010 and 2011 at research farm of the Regional Agricultural Research Station (RARS) Parwanipur, to study the effect of integrated weed management practices on the performance of dry direct seeded rice. Ten treatment combinations viz; weedy, weed free (weekly), Pendimethalin fb (followed by) Bispyribac, Pendimethalin fb two hand weeding, Stale seedbed fb Bispyribac, Stale seedbed fb Pendimethalin fb Bispyribac, Mulch 4 t/ha fb Bispyribac fb one hand weeding, Stale seedbed fb mulch 4 t/ha fb Bispyribac, Pendimethalin and Sesbania co-culture fb 2,4-D Na salt fb one hand weeding and Pendimethalin fb 2,4-D fb one hand weeding were tested in a randomized complete block design and replicated thrice. Observations were taken on weed, plant growth and yield attributes, yield, and socio-economic parameters. All weed control treatments significantly reduced the weed density and dry weight of weed resulting significant increase in yield of DSR over weedy check in both years. Weed free treatment resulted the highest yield, however, it was not economical due to high cost of cultivation. The use of Pendimethalin fb 2,4-D fb one hand weeding produced yield (5161 in 2010 and 6160 kg/ha in 2011) which were statistically at par with yield (5305 in 2010 and 6319 kg/ha in 2011) obtained under the weed free treatment. Further, the highest benefit cost ratio (CBR) 1.77 and 2.22 and net return Rs 47700 and 75084/ha during 2010 and 2011, respectively, were obtained under this treatment indicating its superiority over other treatments. The grain yield, yield attributing characters viz. panicles per m2, panicle weight, filled grain per panicle, thousand grain weight as influenced by different weed management practices revealed that higher yield resulted from weed free plot followed by Pendimethalin followed by two hand weeding and Pendimethalin followed by 2,4-D followed by one hand weeding. However, the net return per unit investment resulted highest in Pendimethalin followed by 2,4-D followed by one hand weeding. This proved that amid increasing wage rate and labor scarcity integrated weed management through Pendimethalin 30 EC (stomp) @ 1 kg a. i./ha as pre- emergence herbicide application followed by 2,4-D sodium salt 80 WP @ 0.5 kg a.i./ha followed by one hand weeding or stale seed bed followed by Pendimethalin 30 EC (stomp) @ 1 kg a. i./ha followed by Bispyribac (nominee gold) @ 25 g a. i./ha 10 % @ 200 ml/ha at 20 days of seeding resulted best alternative for manual hand weeding practices giving higher net return per unit investment.

Abstract
We present a case of kala-azar infection that recurred in a patient after completion of the standard treatment course of miltefosine, amphotericin B-deoxycholate (short course), and amphotericin B lipid formulations. The patient was cured after continuous amphotericin B-deoxycholate administration for 4 weeks. This is a unique case of relapse following the use of three important drugs. Although amphotericin B-deoxycholate is a second line drug in Nepal, it has shown a satisfactory clinical response with continuous treatment for 4 weeks. Therefore, an extended course of amphotericin B-deoxycholate may be beneficial in patients with resistance to the standard short course and other anti-leishmania drugs.
