As spring arrives, so does a renewed focus on cleaning, quality, and process validation in pharmaceutical facilities. Whether it’s a routine seasonal turnover or preparation for ramped-up production cycles, spring is a critical time in the pharmaceutical industry for equipment maintenance, cleaning validation, and ensuring product purity. Behind every cleanroom, batch reactor, or ...

Sterile packaging refers to non-reusable plastic shells, wrappings, and other packing materials that have been terminally sterilized by ethylene oxide (EO), gamma, or autoclave sterilization. Manufacturers use this packaging to ensure that medical devices, instruments, and other healthcare products stay germ-free. ...
These systems consist of two parts: Sterile Barrier System: This system allows penetration by sterilants, such as ethylene oxide gas and gamma radiation. After sterilization, the material maintains the microbial barrier to prevent new germs from entering the packaging. ...
The main aim of this study is to investigate differences in protein expression pathways induced by low doses of radiation in whole blood obtained from radiosensitive and non–radiosensitive patients. ...
Whole body exposure of mice to a sub-lethal dose of 6 Gy gamma radiation resulted in oxidative damage in various tissues of mice, and radiation-induced peroxidative damage and depletion of antioxidants such as GSH, GPx in tissues such as liver, kidney and brain. Administration of SM prior to radiation exposure resulted in ...
POLY MVA, a commercially available health supplement containing α-lipoic acid palladium complex, was evaluated for its potential to enhance the repair of radiation-induced DNA damage. Treatment of human peripheral blood leukocytes with POLY MVA immediately after radiation exposure enhanced the repair of cellular DNA as revealed by comet assay. ...

This study examined the role of melatonin to reduce radiation-induced apoptosis in rat's cervical spinal cord. A number of rats were divided into four groups: (1) control group; (2) group that was treated with intraperitonial injection of melatonin; (3) group that got melatonin 30 min prior to cervical spinal cord gamma irradiation at a dose of 22 Gy; and (4) ...
Whole-body exposure of mice to gamma radiation leads to depletion of tissue antioxidant defence and damages the haematopoietic and gastrointestinal systems in mice. Administration of ascorbic acid-2-glucoside (AsAG) at a dose of 100 mg/kg body weight could prevent the radiation-induced reduction of total White Blood Cell (WBC) count and decrease ...
Ionising radiation is an established etiological agent for breast cancer, but is also a therapeutic modality used in cancer treatment. ...
The present work evaluates the radioprotective effect of curcumin on γ-radiation-induced genetic toxicity. The DNA damage was analysed by the frequencies of Sister Chromatid Exchanges (SCEs). Human lymphocytes were treated in vitro with 5.0 γg/ml of curcumin for 30 min at 37°C then exposed to 1, 2 and 4 Gy γ-radiation. The lymphocytes were cultured in (RPMI) 1640 ...
To address if the modulation of immunity balance by low dose radiation is involved in the enhancement of the anti-tumour function, we examined the effect of 0.5 Gy γ-irradiation on the Th1/Th2 immunity balance in Ehrlich Solid Tumour (EST)-bearing mice. ...
The influence of repeated 0.5 Gy whole-body gamma-ray irradiation on tumour metastasis was examined from the standpoint of tumour invasion in the B16 melanoma pulmonary metastasis model in mice. We confirmed that 0.5 Gy whole-body gamma-ray irradiation (four doses over two weeks) significantly suppressed colony formation in the lungs. ...
Thus, SSBP2, Hsp90 and hnRNP E2 are involved in the radiation response of V79 cells.Keywords: RNA fingerprinting, hnRNP, &, #947, -irradiation, China, hamster cells, RT-PCR, SSBP2, gene expression array, gamma irradiation, low radiation, radioresistant cells, ...
We report here our observations on the low-dose (1.25, 2.50, 5.0 and 10.0 cGy) effects of gamma rays on DNA damage in human peripheral blood leukocytes. In a separate experiment on dose-rate, human blood samples were exposed to a total dose of 10.0 cGy at different dose-rates (0.46, 0.93 and 1.85 cGy/ min) of gamma rays using an industrial radiographic camera. ...
The effect of low-dose gamma-irradiation (0.1 or 0.2 Gy with a dose rate of 0.125 Gy/min) of mice on the spontaneous and high-dose radiation-induced level of cytogenetic damage during ageing of animals was studied using the micronucleus test. It was shown that a single low dose of gamma-radiation induces a cytogenetic adaptive ...
