Development of active packaging film based on poly (lactic acid) incorporated with Piper betel leaf ethanolic extract and its application in the shelf-life extension of tuna meat.

Active packaging films based on poly (lactic acid) (PLA) were developed by adding different concentrations (5 wt% and 10 wt%) of betel leaf (Piper betel) ethanolic extract (BLEE). The extract showed excellent antioxidant (80.2 %) and antimicrobial properties (18.

A survey comparison of educational interventions for teaching pneumatic otoscopy to medical students.

Background: Though pneumatic otoscopy improves accurate diagnosis of ear disease, trainees lack proficiency. We evaluated the effect of three different training techniques on medical students' subsequent reported use of basic and pneumatic otoscopy in patient encounters.

Methods: Pediatric clerkship students participated in an ear exam workshop with randomization to one of three educational interventions: task trainer (Life/form®, Fort Atkinson WI), instructional video, or peer practice.

Transport of anionic azo dyes from aqueous solution to gemini surfactant-modified wheat bran: Synchrotron infrared, molecular interaction and adsorption studies.

From the view of economic efficiency and technology sustainability, biomass adsorbent has a high potential for pollution control. In the present study, the performance of gemini 12-2-12 surfactant-modified wheat bran (MWB) for the removal of anionic azo dyes from aqueous solution was investigated. A new insight was gained into the modification mechanism through synchrotron-assisted infrared analysis and molecular interaction simulation.

Probiotics, prebiotics and colorectal cancer prevention.

Colorectal cancer (CRC), the third major cause of mortality among various cancer types in United States, has been increasing in developing countries due to varying diet and dietary habits and occupational hazards. Recent evidences showed that composition of gut microbiota could be associated with the development of CRC and other gut dysbiosis. Modulation of gut microbiota by probiotics and prebiotics, either alone or in combination could positively influence the cross-talk between immune system and microbiota, would be beneficial in preventing inflammation and CRC.

Biocompatible ι-carrageenan-γ-maghemite nanocomposite for biomedical applications - synthesis, characterization and in vitro anticancer efficacy.

Background: Carrageenans are naturally occurring hydrophilic, polyanionic polysaccharide bioploymers with wide application in pharmaceutical industries for controlled drug delivery. Magnetic nanoparticles with their exceptional properties enable them to be an ideal candidate for the production of functional nanostructures, thus facilitating them for biomedical applications. The development of novel nanocomposite by coupling the synergistic effects of the sulfated polysaccharide (iota carrageenan) and a magnetic nanoparticle (maghemite) may offer new interesting applications in drug delivery and cancer therapy.

An observational study of adults seeking emergency care in Cambodia.

Objective: To describe the characteristics and chief complaints of adults seeking emergency care at two Cambodian provincial referral hospitals.

Methods: Adults aged 18 years or older who presented without an appointment at two public referral hospitals were enrolled in an observational study. Clinical and demographic data were collected and factors associated with hospital admission were identified.

Study of chemical properties and evaluation of collagen in mantle, epidermal connective tissue and tentacle of Indian Squid, Loligo duvauceli Orbigny.

The chemical composition and evaluation of Indian squid (Loligo duvauceli) mantle, epidermal connective tissue and tentacle is investigated in this current study. It is observed that squid mantle contains 22.2% total protein; 63.

Potential of probiotics, prebiotics and synbiotics for management of colorectal cancer.

Colorectal Cancer (CRC) is the second leading cause of cancer-related mortality and is the fourth most common malignant neoplasm in USA. Escaping apoptosis and cell mutation are the prime hallmarks of cancer. It is apparent that balancing the network between DNA damage and DNA repair is critical in preventing carcinogenesis.

Physicochemical characterisation of dietary fibre components and their ability to bind some process-induced mutagenic heterocyclic amines, Trp-P-1, Trp-P-2, AαC and MeAαC.

The physicochemical properties of potato fibre, wheat bran and oat samples were investigated, along with their binding capability to heterocyclic amines (HCAs). Potato fibre displayed highest total dietary fibre content (71.8/100g dry weight basis, dwb), followed by wheat bran (57.

Protective effect of Lactobacillus rhamnosus 231 against N-Methyl-N'-nitro-N-nitrosoguanidine in animal model.

The protective effect of Lactobacillus rhamnosus 231 (Lr 231) against potent carcinogen N-Methyl-N'-Nitro-N-Nitrosoguanidine (MNNG) in the rat model is studied. Daily feeding with Lr 231 improved the body weight of male Wistar rats compared with control groups. Fecal azoreductase (p < 0.
