Poly(4-vinylpyridinium butane sulfonic acid) hydrogen sulfate has been used as an efficient dual acidic catalyst for the one-pot preparation of 1-amidoalkyl-2-naphthols and substituted quinolines under solvent-free *** catalyst was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and thermo-gravimetric analysis. The results revealed several advantages to our new catalyst system,including its reusability,facile work-up procedure, eco-friendly reaction conditions,short reaction time,and high product yields.

One of the most extensively used herbs in traditional Persian medicine (TPM) used in the treatment ofgastrointestinal (GI) disorders, is the plant Artemisia absinthium Linn. (AAL). It also has a wide range of activitiessuch as analgesic and anti-inflammatory, anti-oxidant, anti-fungal, and anti-bacterial activities, hepatoprotective,and neuroprotective activities in addition to having gastroprotective effects. This article is a review comparingTPM resources with new medicines. This review investigates this herb in major TPM sources and strives toextrapolate the exact function it serves in the digestive tract and compares the collected information on the functionof AAL with information found in new medical resource databases such as ISI, Pubmed, Scopus, Google Scholar,and Scientific Information Database. AAL from the Asteraceae family of TPM, known as Afsentin, was used in thetreatment of GI weaknesses, stomach pains, swellings, intestinal parasites, diarrhea, and vomiting. AAL increasedappetite, so it was used for insect repellents and insecticide. Recent studies have indicated that the effects of thisplant improved the symptoms of Crohn's disease and played a role in reducing inflammatory factors. It also hasstrong anti-parasitic, anti-insect, hepatoprotective, and antioxidant effects. Given the widespread use of AAL as atraditional medicine currently in use in different countries, particularly in the treatment of GI diseases, furtherclinical studies that focus on the therapeutic qualities of this plant are required in the future.

The brine discharge from desalination plants affects the benthic communities. Polychaetes are indicators to assess marine pollution. The aim of this study was to examine the effects of brine discharge over softbottom polychaete community in Chabahar Bay. Forty-two sediment samples were collected from seven stations in pre summer monsoon （April 2011） and post winter monsoon （October 2011） using Van Veen grab sampler. Changes in the polychaeta data assemblages were analyzed using univariate and multivariate techniques. Thirty-one polychaete species were identified with the highest abundance in station 6 in pre monsoon period and the lowest abundance in station 1 in pre monsoon. The results showed that the abundance, richness and diversity indices were decreased in the stations near the discharges area comparing to control stations far from the brine discharges zone. CCA （Canonical correspondence analysis） showed that salinity and temperature have influenced the community structure of polychaeta.

Background: Dopamine has been known to facilitate male sexual function. Methods: The effect of aqueous extract (140 mg/kg) of Phoenix dactylifera date palm pollen on sexual behavior and determining of dopamine transmission in the nucleus accumbens was studied in male rats using in vivo microdialysis. Results: Releasing of dopamine increased significantly in the nucleus accumbens when a receptive female was introduced behind a screen (p 0.001). During copulation, dopamine increased markedly in control and treated rats. Phoenix dactylifera Date Palm Pollen enhanced the orientation of males towards females by increasing mounting and ano-genital investigatory behavior. Improving of sexual behavior and dopamine release was higher in treated rats in comparison with control (p 0.001). Conclusion: These results indicate a neurochemical basis for interaction between dopaminergic agents and male sexual behavior. Therefore, Phoenix dactylifera Date Palm Pollen seems to act as a dopamine agonist and to cure male infertility. It can be used as an aphrodisiac that leads to further increases in dopamine release.
