Abstract
In the era of wearable electronic devices, which are quite popular nowadays, our research is focused on flexible as well as stretchable strain sensors, which are gaining humongous popularity because of recent advances in nanocomposites and their microstructures. Sensors that are stretchable and flexible based on graphene can be a prospective 'gateway' over the considerable biomedical speciality. The scientific community still faces a great problem in developing versatile and user-friendly graphene-based wearable strain sensors that satisfy the prerequisites of susceptible, ample range of sensing, and recoverable structural deformations. In this paper, we report the fabrication, development, detailed experimental analysis and electronic interfacing of a robust but simple PDMS/graphene/PDMS (PGP) multilayer strain sensor by drop casting conductive graphene ink as the sensing material onto a PDMS substrate. Electrochemical exfoliation of graphite leads to the production of abundant, fast and economical graphene. The PGP sensor selective to strain has a broad strain range of ⁓60%, with a maximum gauge factor of 850, detection of human physiological motion and personalized health monitoring, and the versatility to detect stretching with great sensitivity, recovery and repeatability. Additionally, recoverable structural deformation is demonstrated by the PGP strain sensors, and the sensor response is quite rapid for various ranges of frequency disturbances. The structural designation of graphene's overlap and crack structure is responsible for the resistance variations that give rise to the remarkable strain detection properties of this sensor. The comprehensive detection of resistance change resulting from different human body joints and physiological movements demonstrates that the PGP strain sensor is an effective choice for advanced biomedical and therapeutic electronic device utility.

Abstract
PURPOSE The present study reports a very rare case of Trypanosoma theileri like infection in the peritoneal fluid of a 6-year-old female Holstein Friesian (HF) cattle brought to Veterinary Clinical Complex, Lala Lajpat Rai University of Veterinary and Animal Sciences (LUVAS), Hisar. The aim of the clinical study was to report an unusual case of T. theileri-like infection associated with peritonitis and its therapeutic management. METHODS For confirmatory diagnosis, peritoneal fluid and blood sample was collected from animal for haemato-biochemical examination, buffy coat examination and detection of Trypanosoma antigen by monoclonal antibody-based latex agglutination test. RESULTS Animal had history of anorexia, high fever, oedematous swelling on the abdominal area and decrease in milk yield since 1 week. Clinical examination revealed high fever, congested conjunctival mucus membrane and oedematous inflammatory swelling on the abdominal region. Haematological examination on Day 1 revealed relative neutrophilia and eosinophilia, whereas other parameters measured were on the lower side of normal range. Thin blood smear examination did not reveal any parasite on first attempt. However, after confirmation of Trypanosoma species in peritoneal fluid collected by FNAC, buffy coat examination of blood sample was also found positive for Trypanosoma species. On Day 2, haematological examination revealed neutrophilic leucocytosis, eosinophilia and anaemia. Blood sample was also found serologically positive for Trypanosoma antigen by monoclonal antibody based latex agglutination test. Biochemical examination revealed increased blood urea nitrogen (BUN), gamma glutamyl transferase (GGT) levels, hyperglycemia, hyperprotienemia and decreased levels of sodium and chloride ions. Animal was primarily treated with isometamidium chloride (Nyzom®) @ 0.5 mg/kg body weight (IM, single dose) along with supportive therapy. CONCLUSION Animal showed clinical recovery after 10 days of treatment. Post-recovery, blood sample of the animal was re-examined for parasite and other blood parameters and it was found negative for presence of Trypanosoma infection along with restoration of haematological values. Hence, the present study concludes the confirmatory diagnosis and therapeutic use of isometamidium hydrochloride along with anti-inflammatory drugs to Trypanosoma infection.

Abstract
Staphylococcus aureus (S. aureus) is the most prevalent microorganism associated with mastitis in cattle, which harbours several virulence factors and antibiotic resistance genes. The present study aimed to characterize S. aureus isolated from mastitic milk of the cattle for antibiotic resistance (blaZ and mecA), haemolysins (hla and hlb) and enterotoxins (sea, seb, sec, and sed) genes. A total of 69 staphylococci were isolated and phenotypically characterized for haemolytic properties on 5% sheep blood agar medium. Out of 69 isolates, 55 (79.71%) were identified as S. aureus by polymerase chain reaction assay. Among S. aureus, the majority of the isolates harboured the gene blaZ (92.73%), followed by coa (89.09%), hlb (60%) and hla (49.09%). Gene mecA responsible for methicillin resistance was detected in 23.64% of S. aureus isolates. Enterotoxin genes seb (9.09%), sec (1.82%) and sed (7.27%) responsible for food poisoning were detected at a comparatively lower rate and none of the S. aureus strain was found positive for sea. Additionally, antimicrobial susceptibility study of S. aureus against 18 antimicrobial discs showed maximum resistance to oxytetracycline, penicillin, and fluoroquinolone groups, contrarily, we observed maximum sensitivity to methicillin and cefuroxime antimicrobials. The high occurrence rate of S. aureus harbouring genes for virulence factors and antimicrobial resistance needs appropriate strategies to control the pathogen spread to the human population.

Abstract
OBJECTIVE To highlight causal relationship between stress fracture in the presence of tarsal coalition and hindfoot pain in adolescents on magnetic resonance imaging (MRI). MATERIAL AND METHODS A retrospective review was performed of the clinical and MRI imaging findings of 6 adolescents referred for MRI to evaluate symptoms of hindfoot pain with possible tarsal coalition. MRI studies were systematically assessed for cause of hindfoot pain, types of tarsal coalition, patterns of stress fractures, bone marrow oedema and any other associated features. RESULTS All the 6 patients (4 male: 2 female) aged between 12 and 19 years developed insidious onset of hindfoot or midfoot pain over a period of weeks to months. On MRI, all 6 cases had features of fibrous tarsal coalition predominantly in the calcaneonavicular articulation (5 out of 6 patients). Associated stress fractures/response were in the posterior facet/body of the calcaneus (3), talar head (2), cuboid (1) and third metatarsal bone in one patient. CONCLUSION Stress fractures/response adjacent to tarsal coalition could be because of altered biomechanics and can be an unusual cause of hindfoot pain in adolescents. A high index of suspicion and complementary MRI findings is crucial to interpret this condition to direct appropriate patient management.

Abstract
Herein, a novel N-(4-(tert-butyl)-phenyl)-2-chloroacetamide functionalized thiacalix[4]arene architecture, viz TCAN2PA has been synthesized and the sensing behaviour towards metal ions were explored. The probe, TCAN2PA displayed "turn-on" fluorescence response towards Hg(II) ions in acetonitrile over a series of competing common metal ions. A bathochromic shift in absorption band along with a significant "Turn-On" fluorescence behaviour of TCAN2PA was observed upon interaction with Hg(II) ions. The lower rim modification of thiacalixarene with N-(4-(tert-butyl)-phenyl)-2-chloroacetamide actively contributes toward the fluorescence property due to the presence of strong electron-donating aryl amido substituent. Fluorescence titration experiments were conducted to find out the limit of detection and to understand binding stoichiometry as well. The electron transfer interactions between the electron rich TCAN2PA host with Hg(II) ions have been postulated which is also supported by computational modelling insights.

Abstract
Cadmium sulfide (CdS), an II-VI group semiconductor material, is one of the most investigated semiconductors in thin film form. In this work, we synthesized CdS thin films with improved film morphology in the presence of ethylene diamine (EA) as the complexing agent by chemical bath deposition (CD) at lower pH. Detailed characterization reveals the presence of cubic phase CdS with a band gap of 2.39 eV with the resultant morphology significantly influenced by the composition of the growth solution. The resultant CdS films finds prospective application as a humidity sensor with a high sensor response of 2.61 corresponding to 80% relative humidity.

Abstract
AIM The present work involves encapsulation of herbal drug nanocurcumin into the virosomes and compared with a liposome in terms of their in vitro anti-proliferative, anti-inflammatory, and anti-migratory efficacy. METHODS The anti-proliferative, anti-inflammatory, and anti-migratory efficacy of virosome and liposome were compared in HepG2 and CaCo2 cells by using MTT, Nitric oxide scavenging, and Wound healing assay, respectively. RESULTS Size of the optimised NC-Virosome and NC-Liposome was 70.06 ± 1.63 and 265.80 ± 1.64 nm, respectively. The prepared NC-Virosome can be stored at -4 °C up to six months. The drug encapsulation efficiency of NC-Virosome and NC-Liposome was found to be 84.66 ± 1.67 and 62.15 ± 1.75% (w/w). The evaluated minimum inhibitory concentration (IC50 value) for NC-Virosome was 102.7 μg/ml and 108.1 μg/ml, while NC-Liposome showed 129.2 μg/ml and 160.1 μg/ml for HepG2 and CaCo2 cells, respectively. Morphological examination depicts detachment of the cells from substratum after exposure to NC-Virosome for 48 h. CONCLUSION The prepared NC-Virosome provides remarkable in vitro efficacy in both the cell lines with site-specific drug-targeting potential as compared to the liposome, results proved its potential as a drug delivery vehicle for future therapy with reduced toxicity.

Abstract
Introduction: The social lockdown measures imposed to contain the COVID-19 pandemic, have had profound effects on the healthcare systems across the world and India has been no exception to it. The study was aimed to evaluate the impact of COVID-19 on orthopaedic practice in India during the lockdown period and assess the preparedness of orthopaedic surgeons for resuming clinical practice after the initial lockdown was lifted. Materials and Methods: An online survey of 35 questions was conducted to evaluate impact on (i) general orthopaedic practice (ii) hospital protocols (iii) out-patient practice (iv) surgical practice (v) personal protective equipment (PPE) use and (vi) post-lockdown preparedness. Results: A total number of 588 practising orthopaedic surgeons from India completed the survey. Majority (88.3%) found severe impact (>50%) on trauma surgery and non-trauma surgery with significant reduction in out -patient attendance compared to corresponding time in 2019. There were significant changes made in individual hospital protocols (91.7 %). Appropriate required PPE was available in majority of the hospitals (74.3%). No remodelling or upgrading of the existing operating theatre infrastructure was done by most surgeons (89.5%). Conclusion: This pan India survey of orthopaedic surgeons has indicated that COVID-19 has had a profound impact on their outpatient and surgical trauma and non-trauma practice, due to the lockdown and resulted in significant changes to hospital protocols. Preparedness to resume clinical and surgical practice was associated with anxiety in two-thirds of the respondents. Majority of the orthopaedic practitioners felt that they would continue to conduct pre-operative COVID-19 screening and use PPE even after the lockdown is over.

Abstract
The present study represents a formulation of nanocurcumin based hybrid virosomes (NC-virosome) to deliver drugs at targeted sites. Curcumin is a bioactive component derived from Curcuma longa and well-known for its medicinal property, but it exhibits poor solubility and rapid metabolism, which led to low bioavailability and hence limits its applications. Nanocurcumin was prepared to increase the aqueous solubility and to overcome all the limitations associated with curcumin. Influenza virosomes were prepared by solubilization of the viral membrane with 1,2-distearoyl-sn-glycerol-3-phosphocholine (DSPC). During membrane reconstitution, the hydrophilic nanocurcumin was added to the solvent system, followed by overnight dialysis to obtain NC-virosomes. The same was characterized using a transmission electron microscope (TEM) and scanning electron microscope (SEM), MTT assay was used to evaluate it's in vitro-cytotoxicity using MDA-MB231 and Mesenchyme stem cells (MSCs). The results showed NC-virosomes has spherical morphology with size ranging between 60 and 90 nm. It showed 82.6% drug encapsulation efficiency. The viability of MDA-MB231 cells was significantly inhibited by NC-virosome in a concentration-dependent manner at a specific time. The IC50 for nanocurcumin and NC-virosome was 79.49 and 54.23 µg/ml, respectively. The site-specific drug-targeting, high efficacy and non- toxicity of NC-virosomes proves its future potential as drug delivery vehicles.

Abstract
Water in its various forms has been found to be one of the most abundant sources of energy on the planet after solar energy, and hydroelectric power plays a key role in renewable-energy supplies. Traditionally, harvesting tremendous amounts of hydrodynamic energy requires the deployment of complex, bulky, and expensive electromagnetic generators, which become inefficient at lower volumes of flowing or falling water, and then the energy is stored when there is an excess, but these techniques remain largely unperfected. Regardless of the diversity of development strategies, adopted methodologies, and working mechanisms, there are a wide range of energy scavengers, to effectively harness environmental friendly alternative energy sources. Robust, sustainable and technologically effective water energy harvesting devices, especially hydroelectric nanogenerators, are in the research spotlight globally, due to their numerous benefits to society, including cost effectiveness, clean and continuous electricity generation, and environmental applicability. Here the design and working mechanism involved in the development of a microporous polymer membrane assisted unique hydroelectric generator (MPA-HEG) based on triboelectrification and electrostatic induction phenomena is reported, which scavenges energy from continuously dripping water droplets sliding onto the surface of a hydrophobic microporous polymer membrane. MPA-HEG utilizes a very simple architecture that consists of a hydrophobic microporous polymer, poly(tetrafluoroethylene) (PTFE), membrane on a single-sided copper-clad laminate as a substrate and an aluminium electrode. Unlike other reported water energy harvesting devices with similar functionalities, the rational design of MPA-HEG does not necessitate any technologically complex structures to be embedded in the substrate. It has also been revealed that the interaction of water droplets on the smooth, water-resistant solid polymer surface in MPA-HEG switches ‘ON’ and connects the originally disconnected equivalent electrical components at the solid–liquid–solid interfaces, giving an uninterrupted electrical circuit, and transmuting the conservative interfacial effects into a bulk mechanism. Consequently, the instantaneous power output shows a vast increase over equivalent devices that are constrained either to triboelectric interfacial effects or moisture-induced electricity generation. This could serve the purpose of validating the inherent advantages of developing self-powered electronic devices, and this approach can also be effectively exploited for boosted power generation with realistic future applications. Water in its various forms has been found to be one of the most abundant sources of energy on the planet after solar energy, and hydroelectric power plays a key role in renewable-energy supplies.![]()

Abstract
Influenza, a common cause of acute respiratory infections, is an important health problem worldwide, including in India. Influenza is associated with several complications; people with comorbidities and the elderly are at a higher risk for such complications. Moreover, the influenza virus constantly changes genetically, thereby worsening therapeutic outcomes. Vaccination is an effective measure for the prevention of influenza. Despite the availability of global guidelines on influenza vaccination in adults, country-specific guidelines based on regional variation in disease burden are required for better disease management in India. With this aim, the Indian Chest Society and National College of Chest Physicians of India jointly conducted an expert meeting in January 2019. The discussion was aimed at delineating evidence-based recommendations on adult influenza vaccination in India. The present article discusses expert recommendations on clinical practice guidelines to be followed in India for adult influenza vaccination, for better management of the disease burden.

Abstract
Similar to the global scenario, pneumococcal diseases are a significant health concern in India. Pneumococcal diseases occur frequently among adults and are largely preventable through vaccines. Globally, several guidelines and recommendations are available for pneumococcal vaccination in adults. However, owing to wide variations in the disease burden, regulatory landscape, and health-care system in India, such global guidelines cannot be unconditionally implemented throughout the country. To address these gaps, the Indian Chest Society and National College of Chest Physicians of India jointly conducted an expert meeting in January 2019. The aim of the discussion was to lay down specific evidence-based recommendations on adult pneumococcal vaccination for the country, with a view to further ameliorate the disease burden in the country. This article presents an overview of the closed-door discussion by the expert members on clinical practice guidelines to be followed for adult pneumococcal vaccination in India.

Abstract
The incidence of symptomatic radiation induced lung pneumonitis (RILP), a major dose limiting side effect of thoracic radiotherapy, is in the range of 15-40%. Therapeutic options for the prevention and treatment of RILP are limited. Hence there is a need for developing novel radioprotectors to prevent RILP which can be patient compliant. This study sought to evaluate the efficacy of oral 3,3'-diselenodipropionic acid (DSePA), a novel selenocystine derivative to prevent RILP. C3H/HeJ (pneumonitis responding) mice received a single dose of 18 Gy, whole thorax irradiation and a subset were treated with DSePA orally (2.5 mg/kg), three times per week beginning 2 h post irradiation and continued till 6 months. DSePA delayed onset of grade ≥ 2 RILP by 45 days compared to radiation control (~105 versus ~60 days). It also reversed the severity of pneumonitis in 3/10 radiation treated mice leading to significant improvement in asymptomatic survival compared to radiation control (~180 versus ~102 days). DSePA significantly (p < 0.05) reduced the radiation-mediated infiltration of polymorphonuclear neutrophils (PMN) and elevation in levels of cytokines such as IL1-β, ICAM-1, E-selectin, IL-17 and TGF-β in the bronchoalveolar lavage fluid. Moreover DSePA lowered PMN-induced oxidants, maintained glutathione peroxidase activity and suppressed NF-kB/IL-17/G-CSF/neutrophil axis in the lung of irradiated mice. Additionally, this compound did not protect A549 (lung cancer) derived xenograft tumor from radiation exposure in SCID mice. DSePA offers protection to normal lung against RILP without affecting radiation sensitivity of tumors. It has the potential to be developed as an oral agent for preventing RILP.

Abstract
Organic phase change materials (PCMs) have been utilized as latent heat energy storage medium foreffective thermal management. In this work, a PCM nanocomposite, consisting of a mixture of two organicPCMs (referred to as eutectic gel PCM) and minimal amount (0.5 wt%) of nanographite (NG) as asupporting material, was prepared. Differential scanning calorimeter was used to determine the meltingtemperature and latent heat of pristine PCM, paraffin (61.5 °C and 161.5 J/g), eutectic gel PCM (54 °C and158 J/g) and eutectic gel PCM nanocomposite (53.5 °C and 155 J/g). The prepared PCM nanocompositesexhibited enhanced thermal conductivity and ultrafast thermal charging characteristics. The nanocompositeswere employed for two different applications: (i) providing hot water using an indigenously fabricatedsolar water heating (SWH) system and (ii) solar rechargeable glove that can be rapidly warmedand used. Experimental results on SWH system show that the use of PCM nanocomposites helps to increasethe charging rate of PCM while reducing the discharging rate of heat by PCM to water, thus enhancingthe maximum utilization of solar energy and hence improving the efficiency of the SWH system.The experimental results on solar rechargeable glove revealed that the glove has the ability to retain thetemperature up to 3 hours.

Abstract
Introduction Trichloroacetic Acid (TCA) is a versatile peeling agent for treatment of melasma. However, Post-Inflammatory Hyperpigmentation (PIH) is reported to be the most common side-effect associated with TCA peel. Topical Ascorbic Acid (AA) due to its effect as antioxidant and tyrosinase inhibitor helps to prevent PIH and maintains the response. Aim To assess the clinical efficacy, safety and reduction in Melasma Quality of Life (MELASQOL) on combining 20% TCA peel with 5% ascorbic acid cream in epidermal melasma. Materials and Methods This study was conducted in the Department of Dermatology, Pt. Bhagwat Dayal Sharma University of Health Sciences, Rohtak. This was an open labelled prospective randomized study in which 60 patients of epidermal melasma were enrolled for 12 weeks. Patients were divided into two groups: Combination group received 20% TCA peel every two weeks with once daily 5% ascorbic acid cream and Control group received only 20% TCA peel. Melasma Area Severity Index (MASI) was used for evaluating clinical improvement of melasma. Improvement in Quality Of Life (QoL) was assessed by MELASQOL scale in both groups. Adverse effects were evaluated at each visit. All statistical analysis was carried out with SPSS 20th version. The difference in change in mean MASI scoring and MELASQOL scores between the two groups were analysed using Mann-Whitney test. The side effects between the two groups were compared using Chi-square test. Results The combination group demonstrated a statistically significant improvement in MASI, percentage decrease in MASI and quality of life as compared to control group after treatment. At the baseline there was no statistically significant difference in MASI between the two groups (i.e., MASI in combination group and control group were 23.55±4.61 and 23.613±4.088 respectively). However, it was statistically significant at the end of therapy (i.e., MASI in combination group was 9.50±5.31 and in control group was 15.10±4.44). When the results were analysed in terms of percentage decrease in MASI from baseline, there was statistically significant difference in combination group (i.e., 10.87±4.11) as compared to control group (i.e., 6.3±1.97) after 2nd week of therapy. When the mean MELASQOL scores were compared between the two groups at the end of therapy (i.e., 12 weeks), it was found to be statistically significantly lower in combination group (16.60±8.03) as compared to control group (25.90±8.17). Minor adverse effects like post peel erythema, pruritus, burning and stinging sensation were observed in some of the patients, which didn't necessitate termination of the therapy. Conclusion Combination of 20% TCA peel with topical 5% ascorbic acid is a highly effective, safe and promising therapeutic option in treatment of melasma which significantly improves the QoL.

Abstract
NKG2D (KLRK1) is a C-type lectin receptor present on natural killer (NK) cells, γδ, CD8+ and CD4+ T cells. Upon ligand binding, NKG2D mediates activatory and co-stimulatory signals to NK cells and activated CD4+ T cells, respectively. Polymorphisms in NKG2D predispose to infectious diseases, cancer, transplantation and autoimmune disorders. We studied the influence of this NK receptor polymorphism on predisposition to and modification of the disease phenotype in patients with rheumatoid arthritis (RA). Eight different single nucleotide polymorphisms (SNP) in the NKG2 gene were genotyped in 236 patients with RA and 187 controls using Taqman 5' nuclease assays. NKG2D genotype/allele frequency did not differ between patients and controls. Subgroup analysis showed that the frequency of A allele of NKG2D9 and T allele of NKG2D10 was significantly higher in patients with deformities (a marker of severe disease) [11 versus 5%, Pc = 0·03, odds ratio (OR) = 2·44, 95% confidence interval (CI) = 1·09-5·98 and 10 versus 4%, Pc = 0·04, OR = 2·45, 95% CI = 1·05-6·39, respectively], while the frequency of alleles G of NKG2D9 and A of NKG2D10 was greater in patients without deformities (Pc = 0·03, OR = 0·41, 95% CI = 0·17-0·91 and Pc = 0·04, OR = 0·41, 95% CI = 0·16-0·96). Similar trends of association were observed with deforming phenotype of RA in female patients and deforming young onset RA subgroups. Haplotype analysis revealed that the frequency of haplotype G-C-A-G-A-T-C-C was higher in patients than in controls (12 versus 8%, P = 0·04, OR = 1·61, 95% CI = 1·01-2·55), suggesting that it may predispose to RA. Our study suggests that the NKG2D gene polymorphisms may modify the risk of development and severity of RA.

Abstract
Pegylated interferon α and ribavirin therapy is associated with increased incidence of various systemic and cutaneous side effects. Among the side effects of this therapy, alopecia universalis is a rarely reported side effect which causes significant cosmetic concern to the patient. We report a rare case of alopecia universalis which developed eight weeks after discontinuation of this antiviral combination therapy. This gains importance because it is essential to sensitize the treating gastroenterologist and the dermatologist regarding this rare side effect.

Abstract
Objective: To evaluate polymethyl methacrylate hydrogel microspheres (HMs) as an embolization material in the management of hypervascular craniofacial and spinal lesions. Material and Methods: Sixty-nine patients with vascular lesions of the craniofacial and spinal regions underwent embolization with HM. The pathologies included craniofacial tumours (n=38), cranial arteriovenous malformations (AVMs) (n=7), dural AVM (n=1), cavernous carotid fistula (n=1), spinal tumours (n=7), spinal AVMs (n=6), orbital lesions (n=4) and scalp AVMs (n=5). Surgery was done in 56 patients. The blood loss at surgery, tumour shrinkage, surgical cleavage and ease of removal of tumour was noted from the records. Histopathology was available in 39 patients. A follow-up of 3 months to 6 years was available in 13 patients in whom embolization was the sole treatment. Surgical and histopathological findings were correlated with angio-embolization findings. Results: HMs were easy to inject through the microcatheter with good control. Good devascularization was obtained in 61 patients and partial in 8 patients. Two patients developed complications due to presence of anastomoses between intra- and extracranial circulation and 1 patient due to tumor swelling. Histopathology showed presence of HMs in all the lesions, with minimal inflammatory reaction in 2 patients. Patients with spinal lesions treated with embolization only stabilised in neurologic deficits. Conclusion: HMs are highly suitable as embolization agents in the management of craniofacial and spinal hypervascular lesions.

Abstract
BACKGROUND A combination of calcipotriol and narrow-band ultraviolet B (NBUVB) has been shown to have a superior efficacy as compared to NBUVB alone in psoriasis. Very few studies have been performed using the combination of NBUVB with tacalcitol, a comparatively newer Vitamin D analogue. OBJECTIVE Comparison of the efficacy and safety of topical tacalcitol in combination with NBUVB versus NBUVB alone in psoriasis. METHODS Thirty patients with plaque psoriasis were taken up for a 12 week, open-label, right-left intra-individual clinical trial. NBUVB phototherapy was given thrice weekly. The target lesions on one side were treated topically with tacalcitol ointment once daily, while no topical treatment was given on the other side. Efficacy was assessed by target plaque scoring. RESULTS Better improvement in plaques was seen with combination therapy as compared to NBUVB monotherapy, with a statistically significant difference from 2 to 8 weeks. The combination led to an earlier clearance of plaques and a better maintenance of the response than NBUVB alone. The number of treatment sessions and cumulative NBUVB doses were significantly lower in the tacalcitol-treated group. CONCLUSION Topical tacalcitol enhances the therapeutic effects of NBUVB therapy and exerts a UVB-sparing effect, without increasing the incidence of adverse effects.

Abstract
AIM The present study was undertaken to ascertain the incidence and clinical vital parameters in cases of primary ketosis in Murrah buffaloes brought to teaching veterinary clinical complex, Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar and from adjoining villages of the district Hisar, Haryana, India. MATERIALS AND METHODS The investigation was conducted on 24 clinical cases (out of total 145 screened) of primary ketosis. The diagnosis was confirmed on the basis of clinical signs and significantly positive two tests for ketone bodies in urine (Rothera's and Keto-Diastix strip test). Data collected were statistically analyzed using independent Student's t-test. RESULTS Overall incidence of disease in these areas was found to be 16.55% and all the animals were recently parturited (mean: 1.42±0.14 month), on an average in their third lactation (mean: 2.38±0.30) and exhibited clinical signs such as selective anorexia (refusal to feed on concentrate diet), drastic reduction in milk yield (mean: 64.4±5.35%), ketotic odor from urine, breath, and milk and rapid loss of body condition. All the clinical vital parameters in ketotic buffaloes (body temperature, heart rate, respiration rate, and rumen movements) were within normal range. CONCLUSION Primary ketosis in Murrah buffaloes was the most common seen in the third lactation, within the first 2 months after parturition with characteristics clinical signs and no variability in vital parameters. The disease has severe effect on the production status of affected animal.

Abstract
Aim: The present study was undertaken to ascertain the clinical observation and haemato-biochemical studies on fever of unknown origin (FUO) in buffaloes which were presented for treatment at the Teaching Veterinary Clinical Complex (TVCC), Lala Lajpat Rai University of Veterinary and Animal Sciences (LUVAS), Hisar. Materials and Methods: The investigation was conducted on total 106 clinical cases presented at “TVCC, LUVAS, Hisar.” Diseased animals having history of fever and increased rectal temperature were considered for the current study. Diagnosis of FUO was done on the basis of negative parasitological examination, culture examination, fecal and urine test. The cases in which etiology could not be established (such as pneumonia, metritis, traumatic reticuloperitonitis, urinary tract infection, trypanosomosis, diaphragmatic hernia, Brucellosis, and foreign body) were considered as true cases of FUO. Results: Out of 106 clinical cases different etiologies were identified in 76 (71.70%) cases including pneumonia, traumatic pericarditis, trypanosomosis, bacteremia, etc. and 30 cases (28.30%) remained undiagnosed even after detailed investigation. The mean rectal temperature (104.43±0.16°F), respiration rate (56.57±1.51/min) and pulse rate (83.40±1.77/min) of animals (n=30) suffering from FUO were significantly higher, whereas ruminal movement (1.00±0.23) was significantly lower compared to healthy control group. The mean value of hemoglobin, lymphocytes, and packed cell volume were significantly lower, whereas mean value of neutrophils was significantly higher compared to that of healthy control animals. Mean value of serum levels of glucose, phosphorus, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine phosphokinase (CPK), blood urea nitrogen (BUN), and creatinine were found to be significantly higher, whereas mean value of calcium value was significantly lower in all clinically affected animals compared to the healthy control group. Conclusion: About 28.30% cases of fever in buffaloes were found to be of unknown origin. Haemato-biochemical findings in cases of FUO in buffaloes revealed relative neutrophilia with lymphopenia, hyperglycemia, hypocalcemia, hyperphosphatemia, significantly increased AST, ALT, and CPK along with adversely altered kidney function indicators (elevated BUN and serum creatinine).

Abstract
Background. Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease with serious impact on quality of life (QoL). There are limited studies available supporting coexistence of sino-nasal involvement in COPD. Methods. A prospective study was conducted to evaluate sino-nasal status in patients with COPD (n=100) presenting to the Department of Respiratory Medicine, Mahatma Gandhi Medical College and Hospital, Jaipur from July 2011 to October 2012. COPD was diagnosed based on the Global initiative on Obstructive Lung Disease (GOLD) guidelines. Sino-nasal status was assessed by detailed history, radiograph of the para-nasal sinuses (PNS), nasal endoscopy and mucociliary clearance time. Results. Sino-nasal symptoms were present in 74 patients with COPD; nasal discharge (75.7%) being the most common. Tobacco smokers with COPD had a higher occurrence of sino-nasal symptoms (76.8%). Radiograph of para-nasal sinuses showed that maxillary sinus was most commonly involved. Nasal endoscopy revealed discharge in 63.5% cases. Nasal mucociliary clearance time was delayed (>11 to >40 min) in 98% cases. Nasal mucociliary clearance time was significantly delayed (>20 min) in COPD patients who were tobacco smokers as compared to non-smokers (53.7% versus 16.7%) and also related with increasing severity of COPD. Conclusions. Our observations suggest that sino-nasal involvement and delayed mucociliary clearance are common in patients with COPD, especially in tobacco smokers. Assessment of upper airway involvement in all the patients with COPD can help better therapeutic intervention and improvement in QoL.

Abstract
Dichlorobis(L-proline) zinc(II) (DCBLPZ) is an excellent nonlinear optical (NLO) material because of its ability to exhibit high second harmonic generation and having significant optical transparency. In this work, electro-optical properties of the titled material has been thoroughly investigated by Hartree–Fock (HF) and Density functional theory using different basis sets in C1 symmetry. The calculated geometrical parametres and vibrational frequencies were found to be in good agreement with reported experimental results. Highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) studies were carried out to understand the intramolecular charge transfer within the molecule. Total dipole moment ([Formula: see text]), polarizability ([Formula: see text]), anisotropy of polarizability ([Formula: see text] and first hyperpolarizability ([Formula: see text]) values were calculated. The static first hyperpolarizability value is found to be six times higher than urea. Ultra violet-visible spectrum of DCBLPZ molecule was calculated by time-dependent density functional theory (TD-DFT) in gas phase using different functionals. The calculated value of absorption wavelength was found at 234[Formula: see text]nm using TD-B3LYP/[Formula: see text]* level of theory and was in good agreement with experimental value (230[Formula: see text]nm) than other applied methods. Our results give us flexibilty to predict about possible intramolecular charge transfer from both the chlorine atoms toward both the proline units through zinc atom in the studied metallic complex. The other important parametres such as frontier molecular orbital’s (FMO), global reactivity descriptors and molecular electrostatic potential have also been calculated and discussed.

Abstract
A series of novel substituted oxacalix[4]arene has been synthesized and explored for their biological profile by evaluating anticancer, antifungal and antibacterial properties. The derivatives have been characterized by various spectroscopic techniques such as IR, (1)H NMR, (13)C NMR and Mass spectrometry. Many compounds showed strong inhibition (MIC) in the range of ∼0-50 μM with interesting cytotoxic activities against Hela cells in particular. The compounds were theoretically evaluated by docking studies as potential histone deacetylase inhibitors (HDACi). The study indicates that compounds bound adequately with HDAC, and hence complemented the experimental findings.

Abstract
Addition of 1,4-benezenedithiol and 4,4'-biphenyldithiol to M(OTf)2 (M = cis-[Pt(PEt3)2](2+) or cis-[Pd(dppe)](2+)) (dppe = 1,2-bis(diphenylphosphino)ethane) gave self-assembled tetranuclear complexes [M2{S(C6H4)nS}]2(OTf)4 (n = 1, 2). The same reaction with 1,4-benezenedimethanethiol yielded octanuclear supramolecular coordination complexes (SCC) [M2{SCH2C6H4CH2S}]4(OTf)8. These complexes were characterized by NMR, mass, and UV-vis spectroscopies, cyclic voltammetry, as well as density functional theory studies and represent the first examples of SCCs constructed by thiolate groups and square-planar metal ions. The rectangular shape of tetranuclear complexes and square shape of octanuclear complex are confirmed by single-crystal structures and computational studies. The palladium complexes showed excellent catalytic activity in Suzuki C-C cross-coupling reactions with high turnover numbers (2 × 10(7)), even with low catalyst loading.

Abstract
A study of elemental composition in the ambient air of Delhi was carried out in the monsoon, winter and summer seasons at four different sites from August 2012 to April 2013 in the size ranges <1, 1-2.5, 2.5-10 and >10 μm using "Dekati PM10" impactor. At each site, three samples were collected and were analyzed by energy-dispersive X-ray fluorescence (EDXRF). The presence of elements was found to be very common and highly concentrated in aerosol particles at all the sites, which are Na, Al, Si, K, Ca, Zn and Ba. Total suspended particulate matters (TSPMs) of fine particles were found high in comparison to coarse particles at all seasons. The TSPM of fine particles was found to be varied in the range from 303.6 to 416.2 μg/m(3). Similarly, the range of coarse TSPM was observed from 162.9 to 262.8 μg/m(3). Correlation matrices were observed between fine (size ranges <1 and 1-2.5 μm) and coarse (size ranges 2.5-10 and >10 μm) size particles for all elements with seasons. Source apportionments of elements were carried out using MS Excel 2010 through XLSTAT software. The source apportionments between fine and coarse particles were carried out through factor analysis and dominated sources found to be crustal re-suspension and industrial activities.

Abstract
Dermatology world is brimming with myriad of interesting clinical conditions, signs and syndromes. It is infinite, which has systemic clinical connotations too. Complicated pronunciations of diagnosis have always placed residents in an intricate state. Each one is trying his best to make this cumbersome subject comparatively more acceptable and convenient. The present paper is an attempt to further simplify the subject by correlating difficult conditions with commonly used and seen things such as fruit and food. A total of 45 dermatological conditions were found to be based on fruit and food eponyms. For example, strawberries can remind us of strawberry gums of Wegener's granulomatosis and strawberry nevus.

Abstract
The present work proposed a nanocellulose (NC)-silver nanoparticles (AgNPs) embedded pebbles-based composite material as a novel reusable cost-effective water purification device for complete removal of dyes, heavy metals and microbes. NC was prepared using acid hydrolysis of cellulose. The AgNPs were generated in situ using glucose and embedded within the porous concrete pebbles by the technique of inter-diffusion of ion, providing a very strong binding of nanoparticles within the porous pebbles and thus preventing any nanomaterials leaching. Fabrication of a continual running water purifier was achieved by making different layering of NC and Ag nano-embedded pebbles in a glass column. The water purifier exhibited not only excellent dye and heavy metal adsorption capacity, but also long-term antibacterial activity against pathogenic and non-pathogenic bacterial strains. The adsorption mainly occurred through electrostatic interaction and pore diffusion also contributed to the process. The bed column purifier has shown 99.48% Pb(II) and 98.30% Cr(III) removal efficiency along with 99% decontamination of microbial load at an optimum working pH of 6.0. The high adsorption capacity and reusability, with complete removal of dyes, heavy metals and Escherichia coli from the simulated contaminated water of composite material, will provide new opportunities to develop a cost-effective and eco-friendly water purifier for commercial application.

Abstract
Bronchial asthma is an important public health problem in India with significant morbidity. Several international guidelines for diagnosis and management of asthma are available, however there is a need for country-specific guidelines due to vast differences in availability and affordability of health-care facilities across the globe. The Indian Chest Society (ICS) and the National College of Chest Physicians (NCCP) of India have collaborated to develop evidence-based guidelines with an aim to assist physicians at all levels of health-care in diagnosis and management of asthma in a scientific manner. Besides a systematic review of the literature, Indian studies were specifically analysed to arrive at simple and practical recommendations. The evidence is presented under these five headings: (1) definitions, epidemiology and impact, (2) diagnosis, (3) pharmacologic management of stable disease, (4) management of acute exacerbations, and (5) non-pharmacologic management and special situations. The modified grade system was used for classifying the quality of evidence as 1, 2, 3, or usual practice point (UPP). The strength of recommendation was graded as A or B depending upon the level of evidence.
