The genus Mentha encompasses mint species cultivated for their essential oils, which are formulated into a vast array of consumer products. Desirable oil characteristics and resistance to the fungal disease Verti- cillium wilt are top priorities for the mint industry. However, cultivated mints have complex polyploid ge- homes and are sterile. Breeding efforts, therefore, require the development of genomic resources for fertile mint species. Here, we present draft de novo genome and plastome assemblies for a wilt-resistant South African accession of Mentha Iongifolia （L.） Huds., a diploid species ancestral to cultivated peppermint and spearmint. The 353 Mb genome contains 35 597 predicted protein-coding genes, including 292 disease resistance gene homologs, and nine genes determining essential oil characteristics. A genetic linkage map ordered 1397 genome scaffolds on 12 pseudochromosomes. More than two million simple sequence repeats were identified, which will facilitate molecular marker development. The M. Iongifolia genome is a valuable resource for both metabolic engineering and molecular breeding. This is exemplified by employing the genome sequence to clone and functionally characterize the promoters in a peppermint cultivar, and demonstrating the utility of a glandular trichome-specific promoter to increase expression of a biosynthetic gene, thereby modulating essential oil composition.

Powerful storage, high performance and scalability are the most important issues for analytical databases. These three factors interact with each other, for example, powerful storage needs less scalability but higher performance, high performance means less consumption of indexes and other materializations for storage and fewer processing nodes, larger scale relieves stress on powerful storage and the high performance processing engine. Some analytical databases （ParAccel, Teradata） bind their performance with advanced hardware supports, some （Asterdata, Greenplum） rely on the high scalability framework of MapReduce, some （MonetDB, Sybase IQ, Vertica） highlight performance on processing engine and storage engine. All these approaches can be integrated into an storage-performance-scalability （S- P-S） model, and future large scale analytical processing can be built on moderate clusters to minimize expensive hardware dependency. The most important thing is a simple software framework is fundamental to maintain pace with the development of hardware technologies. In this paper, we propose a schemaaware on-line analytical processing （OLAP） model with deep optimization from native features of the star or snowflake schema. The OLAP model divides the whole process into several stages, each stage pipes its output to the next stage, we minimize the size of output data in each stage, whether in central processing or clustered processing. We extend this mechanism to cluster processing using two major techniques, one is using NetMemory as a broadcasting protocol based dimension mirror synchronizing buffer, the other is predicatevector based DDTA-OLAP cluster model which can minimize the data dependency of star-join using bitmap vectors. Our OLAP model aims to minimize network transmission cost （mint in short） for OLAP clusters and support a scalable but simple distributed storage model for large scale clustering processing. Finally, the experimental results show the speedup and scalability performance.

As total life expectancy increases, the prevalence of age-related diseases such as diabetes and Alzheimer's disease is also increasing. Many hypotheses about Alzheimer's disease have been developed, including cholinergic neuron damage, oxidative stress, and inflammation. Acetylcholine is a major neurotransmitter in the brain and cholinergic deficits leads to cognitive dysfunction and decline. Recent studies have linked diabetes as a risk factor in developing Alzheimer's disease and other types of dementia. The incidence of patients with type II diabetes and increased levels and activity of α-amylase is higher in patients with dementia. It has been shown that aromatherapy with essential oils from the mint family can improve cognitive performance in Alzheimer's disease patients. Selected monoterpenoids from these essential oils are reported to inhibit acetylcholinesterase, both in vitro and in vivo. Terpenoids are small, fat-soluble organic molecules that can transfer across nasal mucosa if inhaled, or penetrate through the skin after topical application, enter into the blood and cross the blood-brain barrier. Recent evidence supports the idea that the common constituents of essential oils also inhibit α-amylase, a starch digestive enzyme that plays an important role in the control of diabetes. The mint family is a fragrant plant family that contains most of the culinary herbs found in the Mediterranean diet. The Mediterranean diet is considered to be one of the healthiest diets in the world, and is found to be beneficial not only for the heart but also for the brain. Herbs used in this diet are rich in antioxidants that can prevent oxidative damage caused by free radicals. However, our study shows that they also contain biologically active compounds with potent α-amylase and acetylcholinesterase inhibitory activities. Consumption of fresh herbs can help boost memory and reduce sugar levels in the body. The use of herbs as a functional food could lead to significant improvements in health.

Objective:To investigate the percutaneous penetration effect of essential oil of mint from Mentha haplocalyx Briq.on the complex active components in Chinese herbal external preparations,and assess its toxicity on the skin cells.Methods:The cytotoxicity of mint oil on HaCaT keratinocytes and CCC-ESF-1 fibroblasts was measured using an MTT assay.Five model drugs with a wide range of lipophilicity,namely osthole,tetramethylpyrazine,ferulic acid,puerarin,and geniposide,were tested using in vitro permeation studies to investigate the percutaneous penetration enhancement effect of mint oil.Secondary structure alterations of skin stratum corneum(SC)were measured using Fourier transform infrared spectroscopy(FTIR).Saturation solubilities and SC/vehicle partition coefficients of the five model drugs with and without mint oil were also determined to understand the potential mechanisms of the essential oil.Results:Half maximal inhibitory concentration(IC50)values of mint oil were significantly higher in HaCaT and CCC-ESF-1 cell lines than values in the well-established and standard penetration enhancer Azone.Conclusions:mint oil at proper concentration could effectively facilitate percutaneous penetration of both lipophilic and hydrophilic drugs,and exhibit higher efficiency for moderate hydrophilic drugs.Mechanisms of penetration enhancement by mint oil could be explained with saturation solubility,SC/vehicle partition coefficient and the secondary structure change of SC.

Soluble and insoluble/bound phenolic compounds and an aqueous infusion of two mint species(Medina and Hasawi),were tested for their total phenolic content,2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonate(ABTS)and 1,1-diphenyl-2picrylhydrazyl(DPPH)radical scavenging activity,iron(Ⅲ)reduction,iron(Ⅱ)chelating and oxygen radical absorbance capacity(ORAC).Furthermore,the potency of the mint extracts in the inhibition of radical-induced DNA scission,human low-density lipoprotein(LDL)cholesterol oxidation,formation of thiobarbituric acid reactive substances(TBARS)in a cooked ground meat system and LPS(lipopolysaccharide)-stimulated cyclooxygenase-2(COX-2)expression in J774A.1 mouse macrophage cells were monitored.Results showed that the soluble phenolics had a higher phenolic content and antioxidant activity than the insoluble-bound extracts and aqueous infusions in most of the assays.Both varieties exhibited notable antioxidant activities and inhibition of LDL cholesterol oxidation,DNA scission and COX-2 gene expression at transcriptional level.However,Medina mint was a more potent antioxidant than the Hasawi mint.High performance liquid chromatography with online tandem electrospray ionization mass spectrometry(HPLC/ESI-MS/MS)analysis of the extracts revealed that rosmarinic acid was the major phenolic compound present in both mint samples.

This work is aimed at investigating regular mint (Mentha × villosa) drying behavior and assessing how the heterogeneous composition of plants affects their drying kinetics. Drying kinetics and sorption isotherms were evaluated for whole branches and their fractions (leaves and stems). Stems and leaves were characterized by measurement of dimensions, apparent density and initial moisture content. The moisture sorption isotherms were obtained under temperatures of 30°C, 40°C and 50°C for branches, stems and leaves and the data were fitted to the GAB model. mint branches and their fractions were oven dried at temperatures from 40°C to 70°C?and were obtained kinetic curves for each part. Water sorption patterns were similar for leaves and stems and the GAB model described well the sorption behavior of both materials. At a constant temperature, the drying rates were higher for leaves in comparison to stems and the differences increased as the temperature was raised. Therefore, depending on drying conditions, the moisture distribution in dried branches might be significantly different. Since the leaves constitute the major fraction in branches, the drying rates of branches were closer to those of leaves. The kinetic curves were fitted to a diffusion model based on an analytical solution of Fick’s second diffusion law and to an empirical model based on artificial neural network (ANN). The results showed that the model based on the ANN predicted the drying kinetics of the different parts better than the diffusive model. A single network was built to describe the kinetic behavior of branches and fractions in the whole range of temperatures investigated. The diffusive model based on fitting effective diffusivity did not provide good predictions of moisture content, probably because neither the dependence of effective diffusivity on the moisture content nor the heterogeneity and shrinking of static beds were considered.

The flow of foreign direct investment(FDI)into a country can benefit both the investing entity and host government.This study employed panel analysis to examine the factors that determine the direction of FDI to the fast-growing BRICS(Brazil,Russia,India,China,and South Africa)and mint(Mexico,Indonesia,Nigeria,and Turkey)countries.First,we used a pooled time-series cross sectional analysis of data from 2001 to 2011 to estimate and model the determinants of FDI for three samples:BRICS only,mint only,and BRICS and mint combined.Then,a fixed effects approach was employed to provide the model for BRICS and mint combined.The results demonstrate that market size,infrastructure availability,and trade openness play the most significant roles in attracting FDI to BRICS and mint,while the roles of availability of natural resources and institutional quality are insignificant.To sustain and promote FDI inflow,the governments of BRICS and mint must ensure that their countries remain attractive for investment by offering a level playing field for investors and political stability.BRICS and mint governments also need to invest more in their human capital to ensure that their economies can absorb substantial skills and technology spillovers from FDI and promote sustainable long-term economic growth.This study is significant because it contributes to the literature on determinants of FDI by extending the scope of previous studies that often focused on BRICS only.

Applications of nanotechnology in agriculture will result in the development of efficient and potential approaches towards the management of insect pests.The toxicity effects of four essential oils peppermint,thyme,camphor and sage oils were tested against the fourth instar larvae of Agrotis ipsilon to select the most effective essential oil to be converted to the nano form.According to the results obtained,peppermint oil was the most toxic compound,which has been used in the present investigation compared with neem oil.The toxicity of bulk and nano-formulations of neem and pepper mint oils were tested against 2nd and 4th instar larvae of A.ipsilon under laboratory conditions of 25±2°C&65-70%R.H.relative humidity The results show that the LC50 value(the concentration used which kill 50%of the tested individuals)of loaded neem or pepper mint were lower(0.62 and 36.47 ppm)compared with neem or pepper mint oil nano-emulsion and bulk neem for the second larval instar.The different formulations of neem are more potent than in case of peppermint oil,as LC50 and LC90 values were significantly lower.The same trend was found concerning the 4th larval instar.Age of treated larvae had a detrimental effect on the response to the compounds tested.It was noticed that the younger larvae were much more sensitive to the prepared compounds compared to the older ones.The least LC50 value for loaded neem nano-emulsion was 6.68 ppm compared with the highest value for bulk neem oil(16.68 ppm).Also,LC90 values followed the same trend as in case ofLC50.Again,the toxicity of loaded peppermint oil had the most insecticidal activity as expressed by the lowest LC50 value(51.9 ppm)with more insecticidal effect than the bulk(125.43 ppm)or nano-emulsion(85.43 ppm).The present results indicated that these novel systems could be used in integrated pest management program for A.ipsilon control.
