This study reports the use of two validated LC with tandem MS (MS/MS) methods to study the residue depletion profile of phenylbutazone (PBZ) and its metabolite oxyphenbutazone (OXPBZ) from equine serum, urine, and muscle, kidney, and liver tissues. One LC-MS/MS method, with an LOQ of 1.0 ng/mL for PBZ and 2.0 ng/mL for OXPBZ, was used for the analysis of the two drugs in the biological fluids (...

Paclobutrazol (PBZ) is a widely used fungicide that shows toxicity to aquatic embryos, probably through rain-wash. Here, we specifically focus on its toxic effect on eye development in zebrafish, as well as the role of retinoic acid (RA), a metabolite of vitamin A that controls proliferation and differentiation of retinal photoreceptor cells, in this toxicity. Embryos were exposed to PBZ with o...

We study the pseudo-Kleene algebras of Dedekind–MacNeille completion ordered set rough determined by a reflexive relation. characterize cases when PBZ and PBZ*-lattices can be defined on these algebras.

Paclobutrazol (Pbz) is a triazol that effectively inhibits vegetative growth in peach. Changes in mineral element concentration have been generally found. However, uneven distribution of the elements in the soil may partially account for these differences. To ascertain these effects, an experiment was designed under controlled conditions, in which sugar beet, used as a model plant, was grown hi...

Glioblastoma (GB) is the most frequent and aggressive primary tumor of the central nervous system. Prognosis remains poor despite ongoing progress. In cases where the gadolinium-enhanced portion of the GB is completely resected, 90% of recurrences occur at the margin of surgical resection in the macroscopically normal peritumoral brain zone (PBZ). Intratumoral heterogeneity in GB is currently a...

Poly(ADP-ribosyl)ation by poly(ADP-ribose) polymerases regulates the interaction of many DNA damage and repair factors with sites of DNA strand lesions. The interaction of these factors with poly(ADP-ribose) (PAR) is mediated by specific domains, including the recently identified PAR-binding zinc finger (PBZ) domain. However, the mechanism governing these interactions is unclear. To better unde...

doi: 10.1111/j.1399-3054.2005.00490.x Rice (Oryza sativa L.) seeds were soaked for 18 h in distilled water in the absence (–PBZ) or presence (þPBZ, a triazole) of 100 mg l 1 paclobutrazol and then air dried. These air-dried seeds were germinated in the dark and then cultivated in a Phytotron. Twelve-day-old –PBZ and þPBZ seedlings were treated or not with CdCl2. Cd toxicity was judged by the de...

Calendula officinalis L. is largely used in composition beds and like cutted flowers. On the other hand, height (30 – 60 cm), difficult cultivate sales potted plant, owing to tipping of pots for disposition plants on tables. Paclobutrazol (PBZ) a vegetal regulator that reduces growth plants. The purpose this study was evaluate initial C. treated with PBZ. experiment conducted greenhouse Floricu...

Eighteen mature, healthy horses were divided into three groups (six per group) receiving either no treatment, 15 consecutive days of phenylbutazone (PBZ), or 15 consecutive days of suxibuzone (SBZ) at recommended label doses. Horses underwent endoscopy before and after the treatment period and were assigned gastric ulcer scores. Gastric ulcer number and severity scores were similar across treat...

The present investigation was conducted to determine the effect of PBZ and ABA on total phenol contents in different parts of Ocimum sanctum. Paclobutrazol (PBZ) a triazole fungicide, having plant growth regulator (PGR) properties, is reported to inhibit gibberellic acid biosynthesis and increase in abscisic acid and cytokinin contents. So, it necessitates the need to investigate the efficacy o...
