Electrostatic adsorptive loading of ciprofloxacin and metronidazole on chitosan nanoparticles to prolong the drug delivery process with preserved antibacterial activities: formulation and characterization.

This study presents the formulation and evaluation of chitosan-based homogeneous nanoparticles of ciprofloxacin (CP) and metronidazole (MTZ) with improved loading efficiency to enhance the controlled release of drug within the human body as well as for the enhancement of the antibacterial activity. The drug-loaded chitosan nanoparticles (CSNPs) were prepared using deacetylated chitosan extracted from shrimp shells. The characterization of the drug-loaded CSNPs were performed by FTIR, XRD, SEM and TEM analyses.

Quail Rearing Practices and Potential for Avian Influenza Virus Transmission, Bangladesh.

In 2015, human influenza surveillance identified a human infection with A/H9N2 in Dhaka, Bangladesh with evidence of exposure to a sick quail. We conducted in-depth interviews with household quail caregivers, pet bird retail shop owners, and mobile vendors, key informant interviews with pet bird wholesale shop owners, one group discussion with pet bird retail shop workers and unstructured observations in households, pet bird wholesale and retail markets, and mobile bird vendor's travelling areas to explore quail rearing and selling practices among households, mobile vendors, and retail pet bird and wholesale bird markets in Dhaka. Every day, quail were supplied from 23 districts to two wholesale markets, and then sold to households and restaurants directly, or through bird shops and mobile vendors.

Recognizing Zooeyia to Promote Companion Animal Welfare in Urban Bangladesh.

The One Health concept of zooeyia refers to the benefits of companion animals in human health and is gaining global research attention. This exploratory study aimed to understand contemporary experiences and perceptions of the social benefits and challenges of living with a companion animal in urban Bangladesh. Thirty-five qualitative interviews were conducted with companion animal owners (20), animal sellers (10), and livestock service department officers (5) from two major cities in Bangladesh, Dhaka and Khulna.

Exploring customers' perceptions of food adulteration at bazaars and supermarkets in Dhaka, Bangladesh; a qualitative exploration.

Background: Food adulteration is an increasingly recognized global public health problem. In low- and middle-income countries like Bangladesh, adulteration is difficult to detect and respond to. We explored customers' perceptions on food adulteration, perception of risk and connections between information, participant characteristics and patterns of adulterated food concerns that impact risk perception in urban Bangladesh.

COVID-19 vaccine rumors and conspiracy theories: The need for cognitive inoculation against misinformation to improve vaccine adherence.

Introduction: Rumors and conspiracy theories, can contribute to vaccine hesitancy. Monitoring online data related to COVID-19 vaccine candidates can track vaccine misinformation in real-time and assist in negating its impact. This study aimed to examine COVID-19 vaccine rumors and conspiracy theories circulating on online platforms, understand their context, and then review interventions to manage this misinformation and increase vaccine acceptance.

COVID-19-Related Infodemic and Its Impact on Public Health: A Global Social Media Analysis.

Infodemics, often including rumors, stigma, and conspiracy theories, have been common during the COVID-19 pandemic. Monitoring social media data has been identified as the best method for tracking rumors in real time and as a possible way to dispel misinformation and reduce stigma. However, the detection, assessment, and response to rumors, stigma, and conspiracy theories in real time are a challenge.

Proteome analysis of roots of wheat seedlings under aluminum stress.

The root apex is considered the first sites of aluminum (Al) toxicity and the reduction in root biomass leads to poor uptake of water and nutrients. Aluminum is considered the most limiting factor for plant productivity in acidic soils. Aluminum is a light metal that makes up 7 % of the earth's scab dissolving ionic forms.

High density trans-admittance mammography development and preliminary phantom tests.

Background: Malignant breast tumor tissue has a significantly different electrical impedance spectrum than surrounding normal tissues. This has led to the development of impedance imaging as a supplementary or alternative method to X-ray mammography for screening and assessment of breast cancers. However low spatial resolution and poor signal to noise ratio has limited the clinical application.

Enhanced skin permeation of salicylate by ion-pair formation in non-aqueous vehicle and further enhancement by ethanol and l-menthol.

Enhancement of skin permeability of salicylate from non-aqueous vehicle by ion-pair formation with either alkylamines or benzylamine as model cationic ions was examined in excised guinea pig dorsal skin. Solubility of salicylate in isopropyl myristate (IPM) was increased by the addition of either alkylamines or benzylamine as counter ions. The increase was more significant in the presence of amines with longer alkyl chains.
