Present study was conducted to explore the herbicidal effect of volatile essential oil of Mentha longifolia (L.) L. and Chenopodium ambrosioides L. against Avena fatua L. weed. A significant effect of essential oil was observed on early seedling growth, chlorophyll content and cellular respiration over a concentration range of 0.01 – 0.25 mg/ml as compared to control ones. More inhibition was o...

Estrogen receptor-mediated induction of zona radiata (ZR) and vitellogenin (VTG) mRNA and protein in rainbow trout (Oncorhynchus mykiss) was compared to assess their utility as biomarkers for exposure to estrogenic compounds. Partial sequences of rainbow trout ZR and beta-actin were cloned by reverse transcriptase polymerase chain reaction (RT-PCR) using degenerate primers based on conserved re...

Polymorphism. A variable number of tandem repeat (VNTR; Nakamura et al., 1987) polymorphism was detected in rainbow trout (Oncorhynchus mykiss Walbaum) using MspI and BgZII. The probe, RVF9303, was isolated from a genomic DNA cosmid library developed from the RTG-2 cell line (Wolf and Quimby, 1962). Method of Detection. Nylon filters containing rainbow trout genomic DNA digested with MspI o...

The genome sequence of Flavobacterium psychrophilum strain CSF259-93, isolated from rainbow trout (Oncorhynchus mykiss), consists of a single circular genome of 2,900,735 bp and 2,701 predicted open reading frames (ORFs). Strain CSF259-93 has been used to select a line of rainbow trout with increased genetic resistance against bacterial cold water disease.

Cathelicidin antimicrobial peptides (CAMPs) represent a crucial component of the innate immune system in vertebrates. Although widely studied in mammals, little is known about the structure and function of fish CAMPs. Further to the previous findings, two more cathelicidin genes and multiple transcripts from rainbow trout were identified in the present study. Interestingly, we found that trout ...

background: dysmenorrhea which means menstrual pain is the most common complaint in women and is one of the problems of health care. iranian traditional medicine (itm) considers dysmenorrhea as osre-tams and mentha longifolia has been indicated as one of the plants that is effective for its treatment. the objective of this study is to evaluate the effect of mentha longifolia on patients with se...

Muscle's contractile properties can vary along different trajectories, including between muscle fiber types, along the body (within a muscle fiber type), and between developmental stages. This study explores the role of the regulatory myosin light chain (MLC2) in modulating contractile properties in rainbow trout myotomal muscle. Rainbow trout show longitudinal variations in muscle activation a...

Background: Food preservation includes procedures to assure higher level of food safety, hygiene and stability. To achieve this goal, the use of combination biopreservatives, such as Essential oils and Probiotics, has gained increased attention. Objective: The aim of this study was to evaluate the antimicrobial effects of Mentha longifolia L. esential oil and Lactobacillus casei aginst Listeri...

The effects of aqueous and ethanolic leaf extracts of Mentha Longifolia on morphine dependence were examined in mice. Dependence was induced using subcutaneous injections of morphine daily for 3 days. On day 4, the last dose of morphine was injected 2 h perior the intraperitoneal injection of naloxone. The number of episods of jumping during 30 minutes after injection of naloxane was considered...
