Photoacoustic imaging has become an emerging tool for theranostic applications. Not only does it help in <italic<in vivo</italic<, noninvasive of biological structures at depths but can also be used drug release and therapeutic We explore near-infrared light-sensitive liposomes coated with gold nanostars (AuNSs) both applications using a photoacoustic system. Being amphiphilic, the lipid bilayer aqueous core enable encapsulation hydrophobic hydrophilic drugs. The AuNSs on surface act as...
Near-infrared (NIR) light-responsive liposomes are attractive carriers for targeted and controlled drug delivery to the superficial organ or tissue (e.g., skin). This work describes development of NIR-responsive by incorporating gold nanostars within composed Phospholipon 90 g cholesterol. Following cellular delivery, photothermal effect around nanostar upon NIR stimulation induces microcavitation liposome phase transition which consequently triggers release encapsulated molecules. Taking...
Female sex workers (FSWs) who inject drugs (FSW-IDs) have a higher risk of HIV infection and transmission. Understanding the socio-demographic characteristics other behaviours among FSW-IDs will help in strengthening targeted interventions for prevention management. In present study, prevalence, associated FSWs injected those did not ID (FSW-NIDs) was determined India.The national cross-sectional, community-based, integrated biological behavioural surveillance conducted 2014-2015 at 73...
HIV prevalence is higher among Men who have Sex with (MSM), owing to their unsafe sexual behavior. Further, MSM indulge in behaviors such as consumption of alcohol/oral drugs and/or injecting during/before sex that poses the risk behaviors, thereby increasing vulnerability HIV. The study aims analyze factors associated infection multi-risk using any substances those do not use substances.Community-based cross-sectional survey design probability-based sampling between October 2014 and...
Background: HIV prevalence among men who have sex with (MSM) is 16.5 times higher than adult prevalence. With a socio cultural context that demands marriage, considerable proportion of MSM in India female sexual partners and act as bridge population. Stratified analysis risk factors homosexual bisexual will be instrumental identifying the high-risk MSM. We aim to identify socio-demographic behavioural associated MSM.
 Methods: Overall, 23081 were enrolled IBBS conducted across between...
The nationwide lockdown implemented due to COVID-19 drastically affected the working pattern of people. Only limited staff were allowed Work At Office (WAO) while rest asked From Home (WFH). Employees both categories faced challenges restricted movements and safety policies. study was planned assess compare lifestyle changes WAO WFH employees during lockdown. An online cross-sectional designed which included Government private sectors. Electronic Data Capture method used collect data after...
BackgroundHIV Sentinel Surveillance among pregnant women attending antenatal care clinics, ANC-HSS, is used to estimate HIV prevalence the general population. Despite declining trend, population in Karnataka still higher than national average (0.22%), with a recent, noticeable stabilization. Demographic analysis on concentrated infection could be potential indicators for targeted interventions as well and prevention of parent child transmission (PPTCT).ObjectivesTo analyse demographics...
The purpose of this study was to analyze trends in HIV prevalence and risk factors associated with infection among pregnant women attending antenatal clinics Odisha State, India.Data were from the Sentinel Surveillance (HSS) women, a descriptive cross-sectional using consecutive sampling method conducted India. Data samples collected select that act as designated sentinel sites India, during three months surveillance period years: 2013, 2015, 2017. All eligible aged between 15 49 years, for...
Periodic tracking of the trends and levels HIV prevalence at regional district helps to strengthen a state's HIV/AIDS response. among pregnant women is crucial for estimation general population. Karnataka one high states in India. Probing provides critical insights into district-level epidemic patterns. This paper analyzes region- district-wise attending antenatal clinics (ANC) from 2003 2019 Karnataka, South India.HIV data collected during Sentinel Surveillance (HSS) between was used trend...
Photo-responsive nanoparticles (NPs) have received considerable attention because of their potential in providing spatial, temporal, and dosage control over the drug release. However, most relevant technologies are still development process unprocurable by clinics. Here, we describe a facile fabrication these photo-responsive NPs with commercially available gold thermo-responsive liposomes. Calcein is used as model to evaluate encapsulation efficiency release kinetic profile upon heat/light...
Stone quarrying activities generate dust and fine particulate matters of silica heavy metals. The prolonged exposure to suspended particulates leads fatal respiratory complications. Occupational pulmonary complications are poorly characterized among quarry workers in Tamil Nadu.This study aims assess function determine the associated risk factors workers.A comparative, cross-sectional was conducted from April 2014 January 2015 at seven stone quarries Chennai residents within a 5 Km radius....
People who inject drugs (PWID) are India’s third-largest vulnerable population to human immunodeficiency virus (HIV) infection. PWID in India confined certain geographic locations and exhibit varying injecting sexual risk behaviors, contributing considerably increasing HIV trends specific regions. Spatial heterogeneity factors among influences prevalence, transmission dynamics, disease management. Stratified analysis of prevalence based on behaviors will be instrumental strategic...
IntroductionHIV Sentinel Surveillance (HSS) among pregnant women is a key indicator to estimate the HIV prevalence in general population, as nearly 85% of transmission India linked heterosexual route. Tracking levels and trends at state, regional, district help prioritize facilitate tailor-made intervention. Here, we analyze region district-wise attending antenatal clinics (ANC) from 2003 2019 Tamil Nadu.MethodsEleven rounds HSS data collected Nadu, were analysed. Consistent sites grouped...
Introduction: Analysis of local risks at sub-national levels and tailored interventions are being emphasized for effective HIV management. Andhra Pradesh (AP) is a high prevalence state in India, with the second-highest number people (PWH) consistent decline level. Probing further into region district-wise trends will provide critical insights sub-regional epidemic patterns. Hence, this paper analyzes regional district-level among pregnant women attending antenatal clinics (ANC) from 2003 to...
The HIV sentinel surveillance (HSS) serves to estimate the levels and trend of prevalence among high-risk, bridge, general population monitors management at national, state, district levels. Data from HSS are valuable in understanding risk factors associated with transmission particular demographic characteristics.The objective was analyze sociodemographic profile pregnant mothers attending antenatal care (ANC) clinics Karnataka, order understand dynamics within Karnataka.Study design: this...
