In the present study, cryopreservation of common carp (Cyprinus carpio) embryos was studied using a stepwise cooling protocol. Embryos at heartbeat stage were selected, placed in 15- ml plastic tubes and stored at -2 °C for 1, 7, 14, and 21 days in 2 different cryopreservation solutions: S1 (methanol + dimethyl sulfoxide + sucrose) and S2 (methanol + propylene glycol + sucrose). Embryo viabilit...

The aims of this study were to determine whether human limbal explant cultures without feeder cells result in expansion of epithelial progenitors and to estimate the optimal expansion time for progenitor cells. Limbal explants from ten human corneas were cultured for 7, 9, 11, 14, 18, and 21 days. Limbal explants from two corneas were enzymatically dissociated or directly cultured for 14 days. ...

introduction: calcium/calmodulin-dependent protein kinase ii (camkii) is highly expressed in the hippocampus, which has a pivotal role in reward-related memories and morphine dependence. methods: in the present study, morphine tolerance was induced in male wistar rats by 7 days repeated morphine injections once daily, and then gene expression profile of α-isoform of camkii (camkiiα) in the hipp...

BACKGROUND The current guidelines recommend 21-day adjunctive corticosteroid therapy for HIV-1-infected pneumocystis pneumonia patients (HIV-PCP) with moderate-to-severe disease. Whether shorter adjunctive corticosteroid therapy is feasible in such patients is unknown. METHODS We conducted a retrospective study to elucidate the proportion of patients with moderate and severe HIV-PCP who requi...

Defects in articular cartilage are often repaired with fresh osteochondral grafts. While fresh allografts provide viable chondrocytes, logistic limitations require surgical implantation within seven days of graft harvest. Here, we provide information on cold preservation of whole intact osteochondral materials that retains cartilage cell viability and function, and histologic and biochemical in...

We assessed two strains of mice [CD-1 and C3H.HeJ (C3H)] with different responses to coxsackievirus B3 (CVB3) infection at 7, 14, and 21 days after inoculation with 105 pfu of CVB3. CD-1 mice developed inflammatory lesions at 7 days that nearly recovered by 21 days; C3H mice demonstrated persistence of infiltrates. Although there were differences in the baseline fractional shortening, it was fu...

The effect of biopesticide - Derisom on certain metabolites and enzymes of carbohydrate metabolism were evaluated in gill, liver, kidney and muscle of Cyprinus carpio during sub-lethal toxicity exposure of 21 days. A dose of 0.28 ppm was taken as the sub-lethal dose. The organs were taken from exposed and control fish at the end of 24 hrs, 7, 14 and 21 days and used for the estimation of total ...
