Abstract Ripening is a complex physiological process that involves changes in reactive nitrogen and oxygen species that govern the shelf-life and quality of fruits. Nitric oxide (NO)-dependent changes in the sweet pepper fruit transcriptome were determined by treating fruits at the initial breaking point stage with NO gas. Fruits were also harvested at the immature (green) and ripe (red) stages. Fruit ripening in the absence of NO resulted in changes in the abundance of 8805 transcripts whose function could be identified. Among these, functional clusters associated with reactive oxygen/nitrogen species and lipid metabolism were significantly modified. NO treatment resulted in the differential expression of 498 genes framed within these functional categories. Biochemical analysis revealed that NO treatment resulted in changes in fatty acid profiling, glutathione and proline contents, and the extent of lipid peroxidation, as well as increases in the activity of ascorbate peroxidase and lipoxygenase. These data provide supporting evidence for the crucial role of NO in the ripening of pepper fruit.

Telah diketahui bahwa selama penyimpanan, sel darah merah mengalami sejumlah perubahan yang mempengaruhi viabilitas dankemampuannya untuk membawa oksigen ke jaringan. Perubahan tersebut digolongkan menjadi perubahan biomekanik dan biokimia.Perubahan biomekanik yang terjadi adalah perubahan membran sel. Selama penyimpanan, sel darah merah mengalami perubahanmorfologi secara pesat, dari bikonkaf menjadi echinocytes dengan tonjolan dan akhirnya menjadi spheroechinocytes. Hilangnya kesatuansel darah merah tersebut menyebabkan pelepasan hemoglobin (hemolisis) dan pembentukan mikropartikel yang dapat menyebabkankomplikasi transfusi. Pelepasan hemoglobin (Hb) dan mikropartikel bebas menyebabkan peningkatan penggunaan Nitric Oxide (NO),sebuah molekul sinyal penting yang berperan dalam aliran darah dan dapat merangsang terjadinya inflamasi. Perubahan kimia lainnyayang dapat terjadi adalah penurunan glukosa dan penumpukan asam laktat, penurunan kalium, kepekatan adenosine triphosphate (ATP)dan 2,3-diphosphoglycerate (DPG). Tidak semua kerusakan sel akibat penyimpanan ini bersifat eryptotic. Penurunan kalium bersifatpasif (suhu yang dingin menyebabkan pompa pertukaran natrium/kalium menjadi tidak aktif). Penurunan DPG juga bersifat pasif,terkait dengan perubahan kekhasan enzim diphosphoglycerate mutase/diphosphoglyceratephosphatase dan penurunan pH. PenurunanNO terjadi karena larutnya NO bersama dengan Hb yang dilepaskan saat hemolisis. Hb plasma lebih cepat bereaksi dengan NO,dibandingkan dengan Hb dalam sel darah merah. Berkurangnya NO ini berperan dalam keadaan patologis yang terjadi sehubungandengan pemberian darah simpan termasuk dalam hal pengangkutan oksigen oleh Hb. Perubahan akibat penyimpanan ini reversibel bilasel darah merah tersebut ditransfusikan kembali ke dalam peredaran. Tolok ukur utama yang dikontrol secara rutin untuk penyimpananRBC adalah 0,8–1% hemolisis, 75% in-vivo survival dalam waktu 24 jam setelah transfusi, volume dan kadar hemoglobin sel darahmerah. Tolok ukur tersebut memang sangat berguna, namun, perubahan biokimia yang berhubungan dengan fungsi vaskular jugaharus dipertimbangkan. Perubahan yang terjadi selama penyimpanan tersebut akan reversibel melalui upaya peningkatan kualitaspenyimpanan, atau menambahkan larutan additive.

We evaluated the effectiveness of antioxidant co-supplementation therapy using Larginine and Pycnogenol<sup>®</sup> in Japanese men with oligoasthenozoospermia and mild erectile dysfunction (ED). A total of forty-seven adult males with oligoasthenoteratozoospermia syndrome (OAT) were eligible for enrollment. The effectiveness of supplementation with a combination of L-arginine 690 mg and French maritime pine bark extract (Pycnogenol<sup>®</sup>) 60mg for OAT and ED was investigated. The sperm concentration was enhanced significantly after treatment 2 and 4 months (11.79 ± 9.86 to 21.22 ± 28.17 and 20.15 ± 23.99 × 106/ml). Significant improvements in the International Index of Erectile Function (IIEF) were observed in the total score of IIEF (57.69 ± 11.04 to 59.43 ± 12.57) and domain of Orgasmic Function (9.01 ± 1.92 to 9.34 ± 1.66) after 4 months of treatment. L-arginine acts to increase the production of nitric oxide and Pycnogenol<sup>®</sup> activates the endothelial nitric oxide synthase and it is a potent antioxidant and inhibitor of inducible nitric oxide synthase. This study suggests that the combination of Pycnogenol<sup>®</sup> and L-arginine (Edicare<sup>®</sup>) is helpful for infertile men to ameliorate simultaneously quality of sperms as well as erectile functions.

The paper presents the results of the monitoring of the inorganic gaseous pollutants such as nitric oxide (NO), sulfur dioxide (SO2), ozone (O3), carbon oxides (CO, CO2), from indoor air of four office spaces, located in urban area of Bucharest � Romania, by using the equipment that detected and recorded, in real time, the concentrations of the compounds. The study aimed to obtain useful information on air quality from office spaces, and for the awareness of acute necessity for action to improve the quality of the indoor environment in which we live and work.
