By the experiment, the optimal technological conditions that the water and oil repellent finishing agent EX-910E is applied in polyester nonwovens were confirmed. The technological conditions include that EX-910E usage is 40g/l, the bridging agent F-2921E usage is 6g/l, the pre-curing condition is 100 × 2/3min, and the curing condition is 160 × 2.5 min. The results of the experiment indicated t...

The increase of cloves and sed nutmeg productions effects in its waste into the environment. However, shell could be use as mosquito repellent. combination essential oil extracted from functions well repellent for mosquitos. This research aims to identified characteristics these two spices by analysing water, carbon aand ash concentrate. Therefore, we found that water level U1 was 1.4573, U2 1....

In the present study we have evaluated the repellent activity of mixture of Curcuma longa, Zanthoxylum limonella and Pogostemon heyneanus essential oils in 1:1:2 ratio at 5%, 10% and 20% concentration against blackflies in northeastern India. Initially the essential oil mixture tested here has been found effective against Aedes albopictus mosquitoes. The average protection recorded in 20% conce...

Both 1-methylisopropyl 2-(2-hydroxyethyl)piperidine-1-carboxylate, (Picaridin((R))) and cyclohex-3-enyl 2-methylpiperidin-1-yl ketone (AI3-37220; 220) have two asymmetric centers, and the four diastereoisomers of each compound are known to have differing degrees of mosquito-repellent activity according to quantitative behavioral assays conducted at the United States Department of Agriculture. C...

Mosquito repellency data on acylpiperidines derived from the U.S. Department of Agriculture archives were modeled by using molecular descriptors calculated by CODESSA PRO software. An artificial neural network model was developed for the correlation of these archival results and used to predict the repellent activity of novel compounds of similar structures. A series of 34 promising N-acylpiper...

A field experiment was conducted to compare the biting behavior of Plasmodium falciparum-infected and uninfected Anopheles on humans using mosquito repellents. Repellent formulations (5% [wt/vol] N,N-diethyl-3-methylbenzamide [deet] or 5% [wt/vol] AI3-37220, a piperidine compound, both in 100% ethanol, or 100% ethanol alone [as a control]) were applied to the lower legs of 3 collectors in each ...

Sixteen compounds were isolated from the leaves and stems of Murrayatetramera Huang. Based on the NMR and MS spectral results, the structures were determined. It was confirmed that the isolated compounds included three new compounds (9, 10 and 13) and one new natural product (8), which were identified asmurratetra A (9), murratetra B (10), murratetra C (13) and [2-(7-methoxy-2-oxochromen-8-yl)-...

Alopecia, which is defined as the loss of hair from the body, encompasses a wide range of hair loss disorders, including alopecia areata and androgenetic alopecia. There is a growing use of botanical sources in dermatology. Accordingly the interest in the use of botanical and natural products for the treatment of alopecia is growing. Here we present a systematic review of natural and botanical ...

Received: January 03, 2017; Accepted: January 11, 2017; Published: January 14, 2017 Biofilm acids lead to secondary caries, which is a main reason for dental restoration failures. Incorporation both protein-repellent and antibacterial agents into dental composite resulted in a much greater inhibition in biofilm activity. This new class of bioactive dental composite with antibacterial and protei...
