This study determined whether cow or goat yogurt administration has a preventive effect on the hepatic damage undergone during an acute liver injury. Acute liver injury was induced by an intraperitoneal injection of d-galactosamine. Groups of mice were fed with cow or goat yogurt for 2 days or 7 days before the d-galactosamine injection. Blood and liver samples were obtained 12 hours after d-galactosamine inoculation. d-Galactosamine induced an increase in serum aminotransaminases, a reduction in the number of blood leukocytes, an enhancement in neutrophil myeloperoxidase activity, a recruitment of leukocytes toward the liver, an increase in cell death, and an alteration in prothrombin time, activated partial thromboplastin time, and fibrinogen levels. Treatment with cow or goat yogurt was effective at increasing leukocyte number and decrease myeloperoxidase activity. We also observed a decrease in leukocyte accumulation in the liver and a reduction in cell death. Activated partial thromboplastin time and fibrinogen were normalized, but prothrombin time only showed an improvement without reaching normal values. Cow or goat yogurts were effective at protecting against an experimental acute liver injury, especially when administered for 7 days.

Composite mats based on submicron biopolyester fibers, such as poly(3-hydroxyalkanoate)s, and zinc oxide(ZnO) nanoparticles have been exploited in medicine and environmental areas, as antibacterial wound dressings or filters. Generally, the resulting mats have to be subjected to UV irradiation in order to promote the formation of reactive oxygenspecies, thus activating the antimicrobial or photocatalytic effect of ZnO. Therefore, investigation related to the influence ofZnO on poly(3-hydroxyalkanoate)s photo-degradation is required. In this context, the present paper addresses the long-termphoto-degradation of nanofibrous poly(3-hydroxybutyrate) (PHB)/ZnO composites derived from two complementaryelectro-hydrodynamic techniques, namely electrospinning or electrospinning/electrospraying tandem processes. A thoroughinvestigation of the as-obtained PHB/ZnO fibrous composites implying the utilization of ATR-FTIR, SEC, and SEM analysispre- and post-aging under UV irradiation (313 nm) for a period of time of 500 h to study the effect of electro-hydrodynamictechnique utilized and the ZnO content on the UV shielding properties of PHB mats.

Background To present the outcomes of the tarsal switch procedure using an anterior approach to correct severe ptosis with poor levator muscle function (<4 mm) with absent or poor Bell’s phenomenon. Methods This retrospective case series included 11 patients with severe neurogenic or acquired myogenic palpebral ptosis. All patients underwent the tarsal switch procedure through an anterior approach from 2012 to 2015. Margin reflex distance (MRD1 and MRD2) and the palpebral fissure were evaluated preoperatively and postoperatively. Data were compared using the Wilcoxon signed-rank test. P-values <0.05 were considered to indicate statistical significance. Results Surgery was performed on 18 eyelids (11 patients). The median age at surgery was 57 years (range, 29-86 years). Four patients had unilateral ptosis and seven had bilateral ptosis. Nine patients had myogenic ptosis and two had neurogenic ptosis. Postoperatively, the chin-up position improved in all patients. The MRD1 increased statistically significantly, from 0 mm preoperatively to 1.0 mm postoperatively (P=0.001). The MRD2 decreased statistically significantly, from 4.5 mm preoperatively to 3.0 mm postoperatively (P=0.001). The palpebral fissure did not change (4.0 mm preoperatively to 4.0 mm postoperatively) (P=0.13). Conclusions The tarsal switch procedure through an anterior approach is an effective alternative for correcting severe ptosis, especially neurogenic or acquired myogenic ptosis. This procedure can be performed with minimal risk of ocular surface exposure and provides stable outcomes.

Objectives. Ménière disease (MD) is an idiopathic disorder that affects hearing and inner ear balance. Intratympanic genta-micin (ITG) is recognized as an effective treatment for uncontrolled MD characterized by persistent vertigo attacksdespite therapy. The video head impulse test (vHIT) and skull vibration-induced nystagmus (SVIN) are validated meth-ods for evaluating vestibular function. A progressive linear relationship has been identified between the slow-phasevelocity (SPV) of SVIN determined using a 100-Hz skull vibrator and the gain difference (healthy ear/affected ear)measured by vHIT. The aim of this study was to ascertain whether the SPV of SVIN was associated with the recoveryof vestibular function following ITG treatment. Consequently, we sought to determine whether SVIN could predictthe onset of new vertigo attacks in patients with MD who were treated with ITG. Methods. A prospective longitudinal case-control study was conducted. Several variables were recorded post-ITG and through-out the follow-up period, followed by statistical analyses. Two groups were compared: patients who experienced ver-tigo attacks 6 months after ITG and those who did not. Results. The sample comprised 88 patients diagnosed with MD who underwent ITG treatment. Of the 18 patients who ex-perienced recurring vertigo attacks, 15 demonstrated gain recovery in the affected ear. However, all 18 patients ex-hibited a decrease in the SPV of SVIN. Conclusion. The SPV of SVIN may be more sensitive than vHIT in identifying the recovery of vestibular function followingITG administration. To our knowledge, this is the first study to illustrate the link between a reduction in SPV and thelikelihood of vertigo episodes in patients with MD who have been treated with ITG.
