Effects of myosin heavy chain (MHC) plasticity induced by HMGCoA-reductase inhibition on skeletal muscle functions
No full text""The rate-limiting step of cholesterol biosynthetic. pathway is catalyzed by 3-hydroxy-3-methylglutaryl. coenzyme reductase (HGMR), whose inhibitors,. the statins, widely used in clinical practice to treat. hypercholesterolemia, often cause myopathy, and. rarely rhabdomyolysis. All studies to date are limited to. the definition of statin-induced myotoxicity omitting to. investigate whether and how HMGR inhibition influences. muscle functions. To this end, 3-mo-old male rats. (Rattus norvegicus) were treated for 3 wk with a daily. intraperitoneal injection of simvastatin (1.5 mg\\\/kg\\\/d),. and biochemical, morphological, mechanical, and functional. analysis were performed on extensor digitorum. longus (EDL) muscle. Our results show that EDL. muscles from simvastatin-treated rats exhibited reduced. HMGR activity; a 15% shift from the fastest. myosin heavy-chain (MHC) isoform IIb to the slower. IIa\\\/x; and reduced power output and unloaded shortening. velocity, by 41 and 23%, respectively, without any. change in isometric force and endurance. Moreover,. simvastatin-treated rats showed a decrease of maximum. speed reached and the latency to fall off the rotaroad. (30%). These results indicate that the molecular. mechanism of the impaired muscle function following. statin treatment could be related to the plasticity of fast. MHC isoform expression.—Trapani, L., Melli, L., Segatto,. M., Trezza, V., Campolongo, P., Jozwiak, A.,. Swiezewska, E., Pucillo, L.P., Moreno, S., Fanelli, F.,. Linari, M., Pallottini, V.

From trap to nursery. Mitigating the impact of an artisanal fishery on cuttlefish offspring.
No full textBackgroundOverexploitation and the impact of several types of human activities have caused declines of marine resources. The direct and active involvement of fishermen in the management of marine resources is effective not only for resource conservation, but also for changing fishermen's attitudes. In this study, we proposed and tested the efficacy and suitability of a measure for mitigating the impact of a trap fishery on cuttlefish eggs in the North Adriatic Sea. This measure directly involves fishermen in promoting the conservation of the early, and more vulnerable, stages of the cuttlefish life cycle.Methodology/principal findingsThrough surveys on fishing boats and interviews with fishermen, we found that traps placed in coastal areas during the cuttlefish breeding season have a high impact on cuttlefish eggs, with over 3 million eggs likely being destroyed by 3750 traps of 15 fishermen in less than 3 miles of coast. The use of removable ropes attached inside traps as an additional substrate for egg deposition allowed the recovery of 23.7% of the eggs deposited on the traps on average, without affecting the catch rate of adults. Experiments examining hatching success in the field highlighted the need for a careful choice of hatching sites to maximise the efficacy of the mitigation measure.Conclusions/significanceThe proposed mitigation measure reduced the impact of fishing on cuttlefish eggs, with no significant effect on the commercial catch. Fishermen showed a positive attitude towards the application of this measure, which is inexpensive and easy to employ. The direct involvement of fishermen in the management of this resource and the maintenance of traditional fishing methods are a novel aspect of the proposed measure and represent the basis for its success
Which sperm parameter limits could really guide the clinical decision in assisted reproduction?
No full textBackground The predictive role of sperm motility and morphology was recently detected in a large sample of more than 20000 assisted reproductive technology (ART) fresh cycles. However, the complete ART procedure consisted of both fresh and frozen-embryos transfers and only a comprehensive evaluation of the entire process could really confirm if these parameters really predict the ART success. The aim of the study was to evaluate which sperm parameter could predict the success of ART. Methods A retrospective, real-world data analysis was performed, enrolling all couples attending ART from 2008 to 2021, including both fresh and frozen cycles and both in vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI) procedures. Results Fresh cycles success (considering live birth rate) was predicted by female age (1.04 [1.02-1.06]), injected oocytes (0.96 [0.93-0.99]), embryo number (0.79 [0.75-0.83]) and progressive sperm motility (0.98 [0.97-0.99]). On the contrary, frozen cycle outcomes were predicted only by sperm motility (0.97 [0.95-0.99]). This prediction was confirmed in IVF but not in ICSI cycles. Conclusion Both female and male parameters predicted the ART success considering the entire path. However, frozen cycle success was predicted only by progressive sperm motility in IVF cycles, suggesting that the potential amelioration of this male parameter is relevant to improve ART success. Those couples expected to obtain the highest embryos after fertilization (low female age and better semen parameters) will have more attempts with frozen cycles and thus would benefit from a potential treatment focused to improve sperm parameters
