Abstract
Cotton bollworm incidence and damages are high in India. In addition, it causes considerable yield loss. A new insecticide formulation Chlorantraniliprole 600 g/L SC was used along with recommended insecticides for managing Spodoptera litura and Helicoverpa armigera in two consecutive experimental trials during the period October 2021 to September 2022. Two foliar applications of Chlorantraniliprole (40 and 30 g a. i/ha) at ten days interval period reduced significantly the larval populations of H. armigera, S. litura without any phytotoxic symptoms in cotton. Chlorantraniliprole application in open field condition was found to be harmless to natural enemy (coccinellids and spiders). Even though, a temporary lessening of natural enemy populations was noticed after spray, progressively the population was increased within a week time. Cotton yield was high in chlorantraniliprole @ 40 g a. i/ha treated plot (22.66, 22.12 q/ha) when compared to untreated control. Similar effect was also noticed in the dose at 30 g a. i/ha (22.35, 21.81 q/ha) and it was statistically on par in both experiments. Residue analysis results confirming that, cotton lint, cotton seed and soil samples collected from treated (30 and 60 g a. i/ha) and untreated samples during harvest were free from chlorantraniliprole residues (below detectable levels of 0.008 μg/g).

Abstract
BACKGROUND Despite the persistent public health problem of positive psychotic symptoms, understanding of symptom specific prevalence rates, clinical correlates and service utilisation are sparse. AIMS The current study aimed to establish prevalence, clinical and service utilisation correlates of hallucinations and delusions in people accessing outpatient clinics in Tamil Nadu, India. METHODS Secondary patient data from outpatient clinics, over a 12-month period, in 2016, was used for analysis (N = 917). Based on the presence of positive psychotic symptoms (PPSx), the sample was divided into four groups for analysis- hallucinations-only (H), delusions-only (D), both hallucinations and delusions (HD) and neither PPSx (N-PPSx). RESULTS Findings indicate that the most prevalent PPSx were hallucinations (10.7%) however, barriers to service utilisation and clinical correlates were associated predominantly with the D and the HD group; as was severe work impairment. Yet, this group was most likely to remain with psychiatric services. Lastly, diagnostic challenges were apparent within the sample. CONCLUSIONS The study revealed that despite more barriers to service utilisation, persons with PPSx remain in contact with services. Yet prognosis remains only moderate at best, indicating other mediating and underlying factors impeding recovery may be interplaying and, therefore, a need for enhanced biopsychosocial approaches.

Abstract
Background The versatile combination of emdogain or enamel matrix derivative (EMD), recombinant human platelet-derived growth factor-BB (rhPDGF-BB), and demineralized freeze-dried bone allograft (DFDBA) has not been utilized in the treatment of intrabony defects yet. Aim The present study attempted to investigate the efficacy of a combination of simple, uncomplicated nature of modified minimally invasive surgical technique (M-MIST) with EMD, rhPDGF-BB, and DFDBA in the surgical management of intrabony defects and to assess the possible favorable effects for a period of 6 months. Patients and Methods Thirty healthy subjects were included in the present double-blind, randomized controlled, two-arm parallel study. The test group was treated with M-MIST by using rhPDGF-BB, EMD, and DFDBA, and the control group was treated with M-MIST by using rhPDGF-BB and EMD. Results Differences between the mean values of primary clinical parameters including relative attachment level, probing depth, and gingival recession at baseline and those at 6 months after surgery were statistically significant in both groups. Inter-group comparison for clinical attachment level gain, probing depth reduction, and change in the position of gingival margin revealed no statistically significant differences. Inter-group comparison revealed significant differences in linear bone growth (LBG) and percentage bone fill (% BF) but no significant differences in the residual defect depth and change in the alveolar crest position. Conclusion The additional use of DFDBA provides superior benefits in terms of LBG and % BF in intrabony defects. This improvement might be attributed to the use of an osteoinductive scaffold.

Abstract
Myopia has reached epidemic levels in recent years. Stopping the development and progression of myopia is critical, as high myopia is a major cause of blindness worldwide. This overview aims at finding the association of time spent outdoors (TSO), near work (NW), and physical activity (PA) with the incidence, prevalence, and progression of myopia in children. Literature search was conducted in PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature, Cochrane Database of Systematic Reviews, ProQuest, and Web of Science databases. Systematic reviews (SR) and meta-analyses (MA) on the TSO, NW, and PA in relation to myopia were reviewed. Methodological nature of qualified studies were evaluated utilizing the Risk of Bias in Systematic Review tool. We identified four SRs out of which three had MA, which included 62 unique studies, involving >1,00,000 children. This overview found a protective trend toward TSO with a pooled odds ratio (OR) of 0.982 (95% confidence interval (CI) 0.979-0.985, I2 = 93.5%, P < 0.001) per extra hour of TSO every week. A pooled OR 1.14 (95% CI 1.08-1.20) suggested NW to be related to risk of myopia. However, studies associating myopia with NW activities are not necessarily a causality as the effect of myopia might force children to indoor confinement with more NW and less TSO. PA presented no effect on myopia. Though the strength of evidence is less because of high heterogeneity and lack of clinical trials with clear definition, increased TSO and reduced NW are protective against myopia development among nonmyopes.

Abstract
The aging effects of Polyethylene terephthalate (PET) microplastics were studied under Fenton process and Seawater. This research work mainly focuses on the aging mechanism of PET microplastics under two different conditions and their effect of aging on the adsorption of organic contaminants. The results of optical microscopic images, Scanning Electron Microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Raman Spectroscopy, carbonyl, carboxyl index, X-ray powder diffraction (XRD) and dissolved organic carbon (DOC) help to understand the aging mechanism of PET microplastics. Parallel factor analysis (PARAFAC) and two-dimensional correlation spectroscopy (2D-COS) were performed using 3D Excitation-Emission Matrix (3D-EEM) to understand the possible dissolved organic matter released during the Fenton process and seawater. The release of protein/phenol like components was observed in seawater whereas humic acid-like component was noted in the Fenton process. Later, the aged PET microplastics were tested for their adsorption capacity towards 4-nitrophenol at three different temperatures (15, 30 and 45 °C). The adsorption capacity of aged microplastics was found to be higher than the normal PET microplastics for all three different temperatures. Hydrogen bonding, n-pi interaction performed a significant role than pi-pi and hydrophobic interaction in the adsorption mechanism. A double layer with double energy model was found to be the best fit in the adsorption processes. The calculated adsorption energies (ΔE1, ΔE2) from the statistical physics modeling also confirms the physisorption mechanism. The above experimental results help to understand the behavior of microplastics at different aging period and how it acts as a carrier for pollutant in the marine environment.

Abstract
The advent of continuous positive airway pressure ventilation as a mode of treatment for respiratory distress syndrome for premature infants has increased the risk of nasal injuries such as pressure necrosis. We describe a case of a 24-week infant who received CPAP ventilation as a mode of ventilatory support for respiratory distress syndrome and the complication of pressure necrosis of the columella. There are many factors that predispose an infant receiving CPAP ventilation to nasal injury. Many strategies can be employed to reduce the incidence of nasal injuries such as the use of nasal barrier dressings, the use of nasal high flow oxygen (nHF) cannula instead of CPAP ventilation, and the use of nasal masks instead of nasal prongs for CPAP ventilation delivery. The treatment of pressure necrosis can be either medical or surgical. The use of ointments or growth sprays can be used in cases of skin breakdown. Surgical reconstruction can be offered in cases of nasal deformity.

Abstract
The dysfunctioning of β-cells caused by the unspecific misfolding of the human islet amyloid polypeptide (hIAPP) at the membrane results in type 2 diabetes mellitus. Here, we report for the first time, the early-stage interaction of hIAPP oligomers on the DMPC (1,2-dimyristoyl-sn-glycero-3-phosphocholine) lipid membrane using electrochemical parameters. Electrochemical techniques are better than other techniques to detect hIAPP at significantly lower concentrations. The surface level interactions between the peptide (hIAPP) and lipid membrane (DMPC) were investigated using atomic force microscopy (AFM), confocal microscopy (CM) and electrochemical techniques such as Tafel polarization, cyclic voltammetry (CV), differential pulse voltammetry (DPV), linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS). Inserting IAPP into the fluid domains results in breaking the lipid-to-lipid interaction, leading to restriction of membrane mobility. The SLateral values of the liposome and IAPP co-solubilized liposome indicates the cooperative insertion of IAPP. Further, a new method of immobilizing a membrane to the gold surface has been employed, resulting in an electrical contact with the buffer, preventing the direct utilization of a steady-state voltage across the bilayer. The electrochemical studies revealed that the charge transfer resistance decreased for 3-mercaptopropanoic acid modified gold (MPA-Au) electrode coated with the liposome and after the addition of IAPP, followed by an increase in the capacitance. The present study has opened up new dimensions to the understanding of peptide-membrane interactions and shows different experimental approaches for the future researchers in this domain.

Abstract
Background and Aim: Foot-and-mouth disease (FMD) is an acute viral infection affecting cloven-hoofed animals causing vesicular erosions in the oral cavity and interdigital space. The present study was undertaken to ascertain the time-dependent changes in clinical, hematological, and biochemical profiles in different breeds of cattle following experimental infection. Materials and Methods: The animals were inoculated with 1.0×104 50% bovine tongue infectious dose (BTID50) by intradermolingual route. Clinical signs were observed, and blood/serum samples were collected at different time intervals. Results: The white blood cell count declined sharply on days 7-13 and recovered on day 14 post-FMD infection. Biochemical analysis of serum markers for vital organ profile revealed no marked damage. However, a significant increase in blood urea nitrogen (BUN) value indicated pre-renal azotemia. Transient hyperthyroidism was indicated by the rise in T3 and T4 that can be correlated with a decrease in triglyceride and total cholesterol levels. In the cardiac damage assessment study, a distinct breed difference was observed wherein Malnad Gidda calves showed no cardiac damage. Conclusion: Except thyroid profile, BUN, and creatine kinase-myocardial band, all other serum biochemical parameters showed no significant abnormalities, whereas lymphopenia is the only hematological change and it is suggested that effective ameliorative measures should be targeted mainly on the feed/water intake, thyroid gland, and the level of lymphocytes.

Abstract
Non-progressive replication of foot and mouth disease virus was observed in mice peritoneal macrophages. Macrophages turns to M1 type polarization in response to FMDV infection. Upregulation of pro-inflammatory cytokines was peak by 8 h FMDV infection. Type I IFN and viperin showed marked upregulation following FMDV infection in the macrophages.
Despite the fact that macrophages link the innate and adaptive arms of immunity, it’s role in the early infection of foot and mouth disease virus (FMDV) is largely unknown. Recently, depletion of macrophages in vivo after vaccination has shown to drastically diminish the protection against FMDV challenge in mouse model. Even the ability of macrophages to reduce or resist FMDV infection is not known hitherto. Therefore, we examined the replication ability of FMDV in mice peritoneal macrophages and the responsiveness in terms of macrophage polarization and cytokine production. Negative strand specific RT-PCR indicated replication of FMDV RNA in macrophages. Absolute quantitation of FMDV transcripts, immunofluorescence studies and titre of the infectious progeny virus revealed that replication peaked at 12 hpi and significantly declined by 18 hpi indicating non-progressive replication in the infected macrophages. Further, significant up regulation of inducible nitric oxide synthase by 8 –12 hpi and increase of M1 specific CD11c + cells by 42.6 % after infection showed that FMDV induce M1 polarization. A significant up regulation of TNFα and IL12 transcripts at 8 hpi supported that M1 macrophages were functional. Further, we studied the expression of Type I to III interferons (IFN) and other antiviral molecules. The results indicate a marked up regulation of Type I IFNα and β by 9.2 and 11.2 fold, respectively at 8 hpi. Of the four IFN stimulated genes (ISG), viperin showed a significant up regulation by 286-fold at 12 hpi in the mice macrophages. In conclusion, the results suggest that replication of FMDV in mice peritoneal macrophages is non-progressive with up regulation of Type I IFN and ISGs. Further, FMDV induces M1 polarization in murine peritoneal macrophages.

Abstract
The modified surgical flap technique for placement of implant in the anterior maxilla has been described. The flap design has been used to achieve optimal soft-tissue contour for implant restoration. A modification in the surgical technique has been employed with the intention to preserve the interdental papilla, which is the key to the maintenance of hygiene and esthetics around anterior implants. This, in turn, prevents black triangles and improves soft-tissue contours. The modified surgical flap method maintains both functional and esthetic values.

Abstract
BACKGROUND Foot and mouth disease (FMD), which causes myocarditis, results in 50% sudden death in the suckling calves. Occurrence of arrhythmias associated with FMD induced myocarditis in calves is not reported hitherto. The present work documents the arrhythmias associated with FMD in calf and their treatment using appropriate antiarrhythmic drugs. CASE DESCRIPTION A three -month-old male Holstein Friesian crossbred calf naturally suffering from FMD was selected for the present study. FINDINGS/TREATMENT AND OUTCOME Cardiac auscultation revealed grade 4 systolic murmurs and electrocardiography (ECG) showed sustained polymorphic ventricular premature complexes (PVPCs) with tachycardia on bipolar base apex lead. Apart from standard treatment, lidocaine 2% was administered at dose of 0.6 mg/kg intravenously over 15 min once a day and sinus rhythm was restored by 76 h post-treatment. Review of ECG and haematobiochemical examination revealed normal findings on 7th day of treatment. CONCLUSION The study demonstrates the presence of sustained PVPCs with tachycardia due to FMD induced myocarditis and the successful use of lidocaine in restoring the sinus rhythm and recovery of the calf.

Abstract
Ruminal impaction due to plastic materials is a condition, in which indigestible plastic foreign bodies accumulate in the rumen of ruminants leading to ruminal impaction, indigestion, recurrent tympany, and many other adverse health effects. It is caused by the indiscriminate feeding of ruminants on indigestible plastic waste materials. The disease is primarily noticed in stray animals residing in urban areas of developing countries. Ingested plastic materials in the rumen slowly release the chemicals in rumen fluid, which intern enter the food chain through milk and meat products. These chemicals have a detrimental effect on human health. At present, exploratory rumenotomy is the only choice for both diagnosis and treatment of ruminal impaction due to plastic materials in ruminants. Control measures include good animal husbandry practices and proper disposal of plastic waste materials. The present review discusses in depth about the epidemiology, pathophysiology, diagnosis, treatment, prevention, and control of ruminal impaction due to plastic materials in ruminants and also highlights its impact on human health.

Abstract
Present study was conducted with the objectives of determining the renal vascular resistance in dogs with diabetes mellitus and to study the correlation between the indices of renovascular resistance with glycemic status, systolic blood pressure (SBP) and proteinuria in dogs with diabetes mellitus. This study was conducted on seventeen diabetic dogs and ten apparently healthy dogs. Increased renal resistive index (RI) and pulsatility index (PI) were observed in diabetic dogs as compared to healthy dogs. Systemic hypertension and proteinuria were observed in 10 and 3 out of 17 diabetic dogs, respectively. Significant positive correlation was observed between the indices of renovascular resistance and fasting blood glucose levels and between the indices of renovascular resistance and serum glycated hemoglobin levels. No correlation was observed between the indices of renovascular resistance and SBP as well as the indices of renovascular resistance and proteinuria. As the indices of renovascular resistance correlate significantly with glycemic status, they can be used as the early marker for kidney damage in diabetic patients. Among these indices renal PI was found to be more sensitive than renal RI.

Abstract
The aim of this study is to investigate the biocompatibility and anti-Vibrio efficacy of green synthesized silver nanoparticles (AgNPs) using an aqueous leaf extract of Adathoda vasica (A. vasica). The green synthesized silver nanoparticles were characterized by UV-vis, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX). A. vasica AgNPs showed significant antibacterial activity against Vibrio parahaemolyticus in agar bioassay and well diffusion method. Further, nanoparticles interactions with bacteria and its antibacterial activity were confirmed by CLSM analysis. In vivo evaluation results confirmed that synthesized A. vasica AgNPs had good antibacterial efficacy and also nontoxic to the Artemia nauplii.

Abstract
BACKGROUND Complete removal of irritants is not possible with mechanical therapy alone. Adjunctive use of systemic administration of antibiotics results in the distribution of drug throughout the body, which can give rise to toxicity. Curcumin (diferuloylmethane), a constituent of Curcuma longa plant, which possess antioxidant, anti-inflammatory, anti-carcinogenic, anti-microbial, anti-hyper algesic and hypocholesterolemic properties. The aim of the present study is to compare the effects of the curcumin gel as an adjunct to subgingival scaling and root planning with the effect achieved using subgingival scaling and root planning alone. MATERIALS AND METHODS Thirty patients either male or female with chronic localized or generalized periodontitis aged between 25 and 60 years with pocket depth of 5-7 mm affecting at least two nonadjacent sites were included. In the experimental site scaling and root planning was performed, followed by placement of the curcumin gel and periodontal pack application. In the control site, subgingival scaling alone was performed followed by periodontal pack application. Parameters included were: Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment loss. These parameters were recorded on day 0, 30 and 45 days. RESULTS Significant reduction in mean was observed in PI, GI, PD and gain in clinical attachment level were demonstrated in both the groups from baseline to 45 days. However, statistical significant reduction was observed in PI at baseline and 30(th) day and GI at 30(th) day. CONCLUSION Curcumin can be effectively used along with scaling and root planning. Future research is required to determine the long-term effects of curcumin on a large sample of subjects.

Abstract
Frenal attachments are thin folds of mucous membrane with enclosed muscle fibers that attach the lips to the alveolar mucosa and underlying periosteum. Most often, during the oral examination of the patient the dentist gives very little importance to the frenum, for assessing its morpholology and attachment. However, it has been seen that an abnormal frenum can be an indicator of a syndrome. This paper highlights the different frenal attachments seen in association with various syndromic as well as non-syndromic conditions.

Abstract
The Pit-1 gene is involved in regulation of muscle growth through controlling the expression of growth hormone, prolactin, and transforming growth factor-β genes in chicken. The objectives of the study were to explore polymorphisms of the Pit-1 gene and to estimate the effect of these polymorphisms on growth traits in PB-1 and control (broiler strain) and IWI (layer strain) chickens. Single-stranded conformation polymorphism followed by sequencing was performed to reveal polymorphisms of the gene. In total, 10 haplotypes were found across the lines. The mRNA expression of Pit-1 varied among haplogroups and had a significant effect on BW and growth rates. The haplogroups showed a significant effect on BW in wk 7 in PB-1 chickens. In control chickens there was a significant effect at d 1 and in wk 2 and 7, and in IWI strains, there was a significant effect at d 1 and wk 6 and 7. The significant association of haplogroups and growth rate was found between 0 and 2 wk in control and between 0 and 2 and 6 and 7 wk in IWI strains. It was concluded that the Pit-1 gene is polymorphic and has a significant effect on growth traits in chickens.
