ABSTRACT: This study were aimed to find out the best organic solvent for fucoxanthin extraction from Sargassum filipendula originated from Madura islands and the extracted pigment was also determined and identified. The fucoxanthin of Sargassum filipendula originated from Madura island was extracted with two different organic solvent namely DMSO: Water and Acetone: Methanol: Water. The extracted fucoxanthin were them determined spectroscopic ally and identified using Liquid Chromatography Mass Spectrometric (LCMS). The results show that DMSO: Water is the best organic solvent. Totally most Fucoxanthin from fresh leaf 0, 1957 ± 0,017 g/g. Fucoxanthin orange, including the group xantofil and carotenoids and are slightly water soluble and fat soluble. This pigment is found in many species of brown algae. Fucoxanthin activity is indicated by the nature of the absorption at a wavelength of 400-540 nm. Fucoxanthin has a unique chemical structure because it has a bond alenat and 5.6 monoepoxide within the molecule. In general fucoxanthin found in brown algae in the form of trans-fucoxanthin. Added by Borrow and Sahidi (2008), consists of clusters alenic fucoxanthin and two epoxy groups. LCMS method has been applied to the analysis fucoxanthin of brown algae Sargassum filipendula. Electrospray Ionization methods receipts (ESI) (LCMS) was investigated for the determination of molecular weight. In the positive ion mode molecular ion adduct (M + H) + (M + Na) + (M + K) + adduct of cations were also detected in the presence of an abundance of a cluster dimer trimmer. Identified by LCMS, to determine for molecular weight (MW) that the compound has a BM fucoxanthin 658.77.

Investigation on Peel Components and Juice Quality of Two Local Cultivars of Tangerine (Citrus reticulata) from Iran

Original Research, D4

Babazadeh Darjazi, B.

J. Life Sci. Biomed., 4(1): 15-22, 2014.

ABSTRACT: The peel components and juice quality of two local cultivars of tangerine were investigated in this study. Peel components were extracted using cold-press and eluted using n-hexane. Then all analyzed by GC-FID and GC-MS. Total soluble solids, total acids, pH value, ascorbic acid as well as density were determined in juice obtained from tangerine cultivars. Thirty and forty-one peel components were identified in Moallem-kooh and adib cultivars respectively including: aldehydes, alcohols, esters, monoterpenes and sesquiterpenes. The major flavour components were limonene, linalool γ-terpinene, (E)-β-ocimene, β-myrcene, α-pinene and sabinene. Between two cultivars examined, Adib showed the highest content of aldehydes and TSS. Since the aldehyde and TSS content of citrus are considered as two of the most important indicators of high quality, cultivar apparently has a profound influence on these factors.

The Analysis of the City and Village Relations and Models in Islamic Countries

Original Research, D6

Hajilou, Z. Karkehabadi Z. and Khajehnabi F.

J. Life Sci. Biomed., 4(1): 26-34, 2014.

ABSTRACT: The spread of Islam across the cities of Iran led to profound changes in the social, economic, and political system of the countries and villages of Iran. This also led to the blossoming of commercial ties inside and outside the country. Urban industries expanded in cities and substantial changes occurred in villages as a result. Being focused on the role and function of cities and villages of every region, these urban-rural currents made changes and influences with concentration on all spatial dimensions of the settlements. These changes and ties may bring about developmental or non-developmental consequences for each urban and rural space (villages). This research tries to study and analyse the reciprocal relations of the surrounding cities and villages of Khorasan Razavi- Central Mashhad district with its surrounding villages by descriptive-analytic method. The way of gathering information for this paper is documentary (library) and field method including questionnaire, observation, interview the villagers and the likes. Results indicate that Mashhad is one of the major centres into which migrants move. This area is distinguished in the region and has a relative priority because of accumulation of wealth, manpower, facilities, and the holy Shrine of Emam Reza (peace is upon him) in this area. The area has a reciprocal communication with its surrounding rural areas. Mashhad has a more dominant position compared to its rural areas. The dominant pattern in this area is the central place pattern and the sphere of influence pattern. Of course, it performs these two functions in recreational-leisure and leisure-resort aspects. As a result, creation and expansion of these functions in rural areas within the past decades have been a spontaneous move with no planned measure on the whole. For this reason it left unfavourable effects and consequences in various fields. Therefore, it is necessary to control and direct these changes toward the integration of city and village based on Islamic documentations in this area.

RashidAbadi, Z. and Khatami, A.

J. Life Sci. Biomed., 4(1): 35-39, 2014.

ABSTRACT: Hafiz and Horace are both among the greatest poets of the world. Despite the differences and dissimilarities in their motifs, concepts, and notion infrastructures, they are somehow similar in their Epicurean notions. Both agree about notions on carpe diem, death acceptance, greed absence, drinking, and being happy leading the readers to perceptiveness and new horizons. It is attempted here to study the Epicurean notions of Hafiz as the presenter of Iranian thinking, and Horace as a versifier of ancient Rome. The following question will be answered in this study: What are the Epicurean notions? Which basic notions of Hafiz and Horace are common in Epicurean domain?

Beauty in the Works of Saadi and Opinions of Croce


Original Research, D8

Nazari, M. and Khatami, A.

J. Life Sci. Biomed., 4(1): 40-45, 2014.

ABSTRACT: Among aesthetic theorists there are two distinct insights: one celebrates originality of nature and the other one celebrates originality of meaning. The first group seeks art in the objective world while the second group seeks it in the subjective world. One of the followers of the second theory was Bendetto Croce, the Italian philosopher. Croce theorizes that beauty is intuition and revelation, which is the same as perceiving beauty. Beauty is not an inborn attribute of phenomena, because it resides in the ego of the perceiver. The present study explored the works of Saadi to conclude that he had been more interested in objective beauty and originality of meaning years before Croce. Moreover, it was concluded that more than half of the aesthetic topics discussed in Saadi’s poetry stressed subjective innate beauty.

The Structural Analysis of Salman Savoji's Jamshid and Khorshid Mathnavy

Original Research, D9

Ghandi, M.T.  and Khatami, A.

J. Life Sci. Biomed., 4(1): 46-52, 2014.

ABSTRACT: Analysing the structure of an exquisite work by a great poet such as Salman Savoji, whose poems are sometimes regarded analogous in rank to the poetry of Khajeh of Shiraz, perhaps leads to an opening in the field of literary sciences. Its rhetoric also brings the conjecture of these two poets' mosha'ereh (or the art of Persian poetry recital) to mind. This possibility is studied from different respects in his Jamshid and Khorshid poem in this situation, which led to some conclusions. Salman has much benefited from his predecessors from many structural and content respects, and has not been unaware of his own unique creativity in composing this love poem. He has sometimes imitated his predecessors in the main plot, and some of his alternatively made episodes have helped him in processing the actions. In addition, adding different occasional sonnets, Stanzas, and quatrains into it in various meters is regarded as one of his matchless artistic  properties. The frequency of some metaphoric compounds and other verbal and figurative rhetoric's also indicates one of his notable and exclusive stylistic characteristics in this poem.

Original Research, D12

Memari, M. and Salehi, M.

J. Life Sci. Biomed., 4(1): 64-70, 2014.

ABSTRACT: To do the purposes of this research, one thousand students and four hundred teachers engaged in Khuzestan pre-university centres were randomly selected. Using open-ended questions for teachers and students to answer, and also strategies identified and defined by different scholars, the researcher formulated and made a valid and reliable questionnaire for the participants of study to answer by giving them to two experts to approve their reliability and validity. All the strategies identified for the questionnaire making were: activating prior knowledge, clarifying, context clues (close procedures), drawing conclusions, evaluating, fix-up (think aloud), inferring (inferential), predicting (anticipating guide), question answer relationship (Q.A.R), rereading, restating, skimming and scanning, key words, surveying (concept-text application), visualizing, request (reciprocal teaching), and interactive notebook. After gathering and analysing data from the two groups, the results of the two groups were compared to see whether the strategies used by teachers and students were matched. Applying appropriate statistics, the following results, were indicated:  Teachers are familiar with some of the strategies that correspond to before and during reading stages. These strategies are b, h, m, and n. Although teachers are familiar with the above mentioned strategies they do not always use them in their teaching.  Teachers use some of the techniques of the familiar strategies not completely. Students apply the e, k, m, and n strategies when studying their lessons. Whereas two of the strategies m, and n, used by the groups are matched, in n strategy students use the techniques related to after reading, and teachers use the techniques related to before and during reading.
