BACKGROUND The efficacy of Piper aduncum essential oil was evaluated against Periplaneta americana adults and nymphs in the laboratory. METHODS The plant essential oil at varying concentrations ranging between 10,000 to 80,000 ppm were placed inside glass beakers, rolled horizontally to ensure the essential oil covers all sides of the beakers and exposed to adults and nymphs of P. americana. ...

We conducted this study to determine the insecticide susceptibility of two malaria vectors, Anopheles dirus and Anopheles minimus from Kanchanaburi Province, Thailand. The mosquitoes were collected and reared under laboratory conditions. The test was carried out on unfed F-1 female mosquitoes using a standard WHO testing protocol. The LD50 and LD90 of deltamethrin in both species were tested fo...

Social bacterial interactions are considered essential in numerous infectious diseases, particularly in wounds. Foot ulcers are a common complication in diabetic patients and these ulcers become frequently infected. This infection is usually polymicrobial promoting cell-to-cell communications. Staphylococcus aureus is the most prevalent pathogen isolated. Its association with Helcococcus kunzii...

Background: Epidemiologic studies show an inverse or U-shaped relation between sleep duration and BMI. Decreases in total energy expenditure (TEE) and physical activity have been suggested to be contributing factors. Objective: The objective was to assess the effect of sleep fragmentation on energy metabolism and energy balance in healthy men. Design: Fifteen healthy male subjects [mean6 SD BMI...

BACKGROUND Opioid analgesics are commonly added to epidural local anesthetics to improve analgesia during surgery. OBJECTIVES The goal of this study was to evaluate the maternal and neonatal effects of adding different doses of tramadol to 2% lidocaine in the epidural anesthesia for cesarean section. PATIENTS AND METHODS Ninety pregnant patients who were candidates for cesarean section unde...

Mortality of German cockroaches, Blattella germanica (L.), caused by Metarhizium anisopliae (Metschnikoff) Sorokin strain AC-1 alone and in combination with different formulations of boric acid, was evaluated in laboratory bioassays. Topical application of M. anisopliae alone (8.96 10 conidia/m) required 28 days to cause >92% cockroach mortality (LT50 10 days). In contrast, in combination with ...

BACKGROUND & OBJECTIVES Phlebotomine sandflies (Diptera: Psychodidae) play main role in the transmission of different forms of leishmaniasis in the world. Phlebotomus papatasi is the main vector of zoonotic cutaneous leishmaniasis (ZCL) in Iran. There are several control measures for vector control using different classes of insecticides. The aim of this study was to breed the sandflies which w...

Remittances and Inequality: A Dynamic Migration Model We develop a model of the interdependencies between migration, remittances and inequality, and investigate how migration and subsequent remittances affect inter-household inequality in the origin communities. An important feature of our model is that we take into account the impact of migration on the local (rural) labor market. Migration is...
