Suhair Al-Nimry  Alaa Abu Dayah  Inas Hasan  Rawand Daghmash 《Marine drugs》2021,19(3)

There are several reviews that separately cover different aspects of fish gelatin including its preparation, characteristics, modifications, and applications. Its packaging application in food industry is extensively covered but other applications are not covered or covered alongside with those of collagen. This review is comprehensive, specific to fish gelatin/hydrolysate and cites recent research. It covers cosmetic applications, intrinsic activities, and biomedical applications in wound dressing and wound healing, gene therapy, tissue engineering, implants, and bone substitutes. It also covers its pharmaceutical applications including manufacturing of capsules, coating of microparticles/oils, coating of tablets, stabilization of emulsions and drug delivery (microspheres, nanospheres, scaffolds, microneedles, and hydrogels). The main outcomes are that fish gelatin is immunologically safe, protects from the possibility of transmission of bovine spongiform encephalopathy and foot and mouth diseases, has an economic and environmental benefits, and may be suitable for those that practice religious-based food restrictions, i.e., people of Muslim, Jewish and Hindu faiths. It has unique rheological properties, making it more suitable for certain applications than mammalian gelatins. It can be easily modified to enhance its mechanical properties. However, extensive research is still needed to characterize gelatin hydrolysates, elucidate the Structure Activity Relationship (SAR), and formulate them into dosage forms. Additionally, expansion into cosmetic applications and drug delivery is needed.  相似文献   

The Effect of Liquid Smoking of Anchovy (Engraulis encrasicolus,L. 1758) Fillets on Sensory,Meat Yield,Polycyclic Aromatic Hydrocarbon (PAH) Content,and Chemical Changes

In this study, the effects of a commercial liquid smoke flavoring agent and two different brining solutions applied on fillets of anchovy were investigated by performing sensory analyses, meat yield, polycyclic aromatic hydrocarbon (PAH) content, and chemical composition analyses. Fillets were brined at 40 and 65% for 4 h at 4°C. Meat yield, sensorial acceptability, and chemical compositions were affected by each brining level. No detectable PAH levels were found in smoke flavoring treated fish samples. Sixty-five percent salt level was rejected by the participants due to high salt content. The results of the study showed that liquid smoke flavoring treatment is applicable to the anchovy fillets, and 40% brining level is recommended.  相似文献   

Effect of dietary garlic supplementation on lipid peroxidation and protein oxidation biomarkers of tissues as well as some serum biochemical parameters in common carp Cyprinus carpio     

Nadia Naeiji  Davar Shahsavani  Hasan Baghshani 《Fisheries Science》2013,79(4):699-705

This study aims to investigate the effects of dietary garlic powder (25 and 50 g kg^?1 feed) supplementation for 6 weeks on lipid and protein oxidation biomarkers in various tissues as well as some blood biochemical parameters in common carp. Based on the present study results, serum malondialdehyde (MDA) concentrations were decreased following garlic supplementation, but the decrease was only significant (P < 0.05) in the group that received 50 g kg^?1 dietary garlic compared with the control group. Moreover, garlic at 50 g kg^?1 diet caused significant decrease in MDA values of liver and kidney. Additionally, the decreasing effect of garlic at 25 g kg^?1 diet on MDA values was only significant in liver. Protein carbonyl contents were only decreased significantly in muscle following garlic administration at 25 g kg^?1 diet. Serum aspartate aminotransferase activity decreased significantly in carp that received 25 g kg^?1 dietary garlic. Moreover, alkaline phosphatase activity decreased significantly in carp fed diets containing 25 and 50 g kg^?1 garlic. On the other hand, garlic supplementation had no significant effect on gamma-glutamyl transferase activity and total protein, albumin, and creatinine concentrations. The results of the present study indicate that garlic powder has potential to decrease oxidative stress to some extent by reducing lipid and protein oxidation in some tissues of common carp.  相似文献

Nikookar SH  Hajheydari Z  Moosa-Kazemi SH  Mahmoudi M  Shahmohammadi S 《Pakistan journal of biological sciences: PJBS》2012,15(2):103-107

Dermatitis caused by stimulation of beetle paederus, is a common health problem in Northern and some southern parts of Iran. Since by now, traditional medicine and some corticosteroid agents have been used for treatment of dermatitis caused by beetle paederus. Because, there are few researches about classical treatment of the disease at academic level, this study planned to compare the effectiveness of triamcinolone ointment and atorvastatin tablet with placebo in treatment ofpaederus dermatitis in Northern Iran. A randomized double-blind clinical trial was carried out on 30 patients referred to the hospital and clinics at Sari and Neka countries in Northern Iran during 6 months. Patients were randomly divided into two therapeutic equal groups. The first group was triamcinolone ointment twice a day and a placebo atorvastatin tablet daily. The second group was oral atorvastatin one tablet (20 mg) daily and a placebo triamcinolone ointment twice a day. In Seventh day of visits, therapeutic response of the patients in triamcinolone and atorvastatin group were 93.33 and 80%, respectively. No significant differences were found in therapeutic outcome between the two groups (p > 0.05). The results showed both oftriamcinolone ointment and oral atorvastatin had similar effect on paederus dermatitis. Because the paederus dermatitis is a self-limited disease use of topical therapy for treatment of the disease is recommend.  相似文献

Fumigant and repellent activities of essential oil from <Emphasis Type="Italic">Coriandrum sativum</Emphasis> (L.) (Apiaceae) against red flour beetle <Emphasis Type="Italic">Tribolium castaneum</Emphasis> (Herbst) (Coleoptera: Tenebrionidae)     

M. S. Islam  M. Mahbub Hasan  W. Xiong  S. C. Zhang  C. L. Lei 《Journal of pest science》2009,82(2):171-177

The biological activity of essential oil extracted from coriander, Coriandrum sativum L. (Apiaceae) against eggs, larvae and adults of Tribolium castaneum (Herbst) was investigated in a series of laboratory experiments. Bioassays conducted in air-tight glass chambers showed vapour toxicity and strong repellency on filter paper arena test towards all the stages used. Responses varied significantly (P < 0.001) within insect stages, dosages and exposures. At 12.0 μg/ml dosage, mortality of adults reached 95%, but for 12-, 14- and 16-days larvae, mortalities were 65, 74 and 82%, respectively. On the developmental inhibition, individuals fumigated at the larval stage confirmed that the percentage of larvae reaching to pupal stage and pupae to adult stage, decreased significantly (P < 0.001) with increasing dosage concentration. The oil fumigation yielded 100% mortality for T. castaneum larvae, pupae and adults at 0.08 μg/ml dosage. The oil had fumigant activity against eggs and the toxicity progressively increased with increased exposure times and concentrations. One hundred per cent T. castaneum egg mortalities were obtained with oil fumigation at 20 μg/ml and 96 h exposure period. C. sativum oil also showed highly repellent activity to the adults of T. castaneum, with overall repellency was 90% and at a dosage of 12 μg/ml repellency was 100% in a filter-paper arena test.  相似文献   

Korean <Emphasis Type="Italic">Brassica oleracea</Emphasis> germplasm offers a novel source of qualitative resistance to blackleg disease     

Arif Hasan Khan Robin  Nicholas J. Larkan  Rawnak Laila  Jong-In Park  Nasar Uddin Ahmed  Hossein Borhan  Isobel A. P. Parkin  Ill-Sup Nou 《European journal of plant pathology / European Foundation for Plant Pathology》2017,149(3):611-623

Blackleg disease, caused by the hemibiotrophic fungal pathogen Leptosphaeria maculans, is one of the most devastating disease of Brassica species worldwide. To date, a total of 20 race-specific blackleg resistance (R) genes have been reported and all of those loci are located in either the A or B genomes of various Brassica species. The B. oleracea genome (CC) shares a high ancestral synteny with the A genome of B. rapa, suggesting the presence of qualitative (race specific) resistance to blackleg disease is also possible in B. oleracea germplasm. In the present study the C genome of Korean B. oleracea germplasm was screened for the presence of blackleg R genes. Thirty-two inbred cabbage lines with unknown resistance profiles, along with five control B. napus lines with well-characterised race-specific R genes, were assessed for cotyledon resistance against two L. maculans isolates with known and highly-contrasting avirulence gene (Avr) profiles. Two cabbage accessions were identified which produced a strong resistance when challenged with either isolate, demonstrating the presence of effective blackleg R genes in the cabbage C genome. Additionally, 16 microsatellite markers linked to seven different R genes of the B. napus A genome were converted into markers for their homologous regions on the B. oleracea C genome. These markers were used to screen all B. oleracea lines to assess if the novel C genome R genes were syntenous to known R gene-homologous regions of the A genome. The resistant cabbage lines offer C genome R genes for the protection of B. oleracea varieties against incursion of blackleg disease, as well as novel additional resistance sources for introgression into B. napus and B. carinata breeding material.  相似文献   

Cd and Nutrient Elements Release into Various Aqueous Solutions from Synthesized K-Struvite Fertilizer     

Hasan Arslanoglu 《Communications in Soil Science and Plant Analysis》2018,49(17):2175-2188

K-struvite (potassium magnesium phosphate, KMgPO₄.6H₂O) is a promising multinutrient slow-release fertilizer; however, it may contain cadmium (Cd) in significant ranges like other phosphorus (P) fertilizers. This paper focuses on dissolution of a synthesized K-struvite in water, acid solutions and complexing agents. Firstly, K-struvite was synthesized by using Cd containing phosphoric acid (H₃PO₄). After its characterization, a three-stage dissolution study was carried out. The release of nutrient elements and Cd into extracts was studied. Phosphorus (P) and potassium (K) solubilities in pure water are low, not more than about 2.5% at the end of three extractions. It was found that solubility increased with the presence of mineral and organic acids. The presence of complexing agents also enhanced the dissolution of K-struvite. At the end of three extractions, citric acid (CA, C₆H₈O₇.H₂O) solution solubilized P about 38%, while dissolved K was about 35%, in cumulative. In the case of 0.001 mol/L Na₂EDTA (C₁₀H₁₄N₂Na₂O₈.2H₂O), the solubilized K-struvite was found to be about 40%, which was about 14% in a 250 mg/L Na-humate. The maximum concentrations of Cd in the third extracts of hydrochloric acid (HCl), CA, oxalic acid (OA, C₂H₂O₄) and Na₂EDTA were measured to be in the range of about 14–19 μg/L, which corresponds to a Cd solubilization more than 46% for the three successive extractions.  相似文献   

Antifungal and antitermitic activities of wood vinegar from oil palm trunk     

Hasan Ashari Oramahi  Tsuyoshi Yoshimura  Farah Diba  Dina Setyawati  Nurhaida 《Journal of Wood Science》2018,64(3):311-317

We evaluated the antifungal and antitermite activities of wood vinegars produced from oil palm trunk. The wood vinegars were produced at three different pyrolysis temperatures, 350, 400, and 450 °C. Antifungal activities of vinegars were evaluated using a Petri dish bioassay with 0.5, 1.0, and 1.5% (v/v) against a white-rot fungus, Trametes versicolor, and a brown-rot fungus, Fomitopsis palustris. Antitermite activities were tested using a no-choice bioassay method for Coptotermes formosanus with 2.5, 5.0, 7.5, and 10.0% (v/v). All the wood vinegars exhibited antifungal activities against T. versicolor. In particular, the wood vinegar produced at 350 °C resulted in complete inhibition of T. versicolor growth at 1.0 and 1.5%. However, higher concentrations were required to obtain growth inhibition of F. palustris. All the wood vinegars exhibited antitermite activity to C. formosanus workers in the no-choice experiment at relatively high concentrations. For instance, 10% concentration was required to achieve 100% mortality against C. formosanus at all production temperatures. The lowest mass loss of the treated filter paper of 11.75% was obtained with a 350 °C—10.0% combination.  相似文献
