Contact zones reveal restricted introgression despite frequent hybridization across a recent lizard radiation.

Introgression - the exchange of genetic material through hybridization - is now recognized as common among animal species. The extent of introgression, however, can vary considerably even when it occurs: for example, introgression can be geographically restricted or so pervasive that populations merge. Such variation highlights the importance of understanding the factors mediating introgression.

Lens-sparing vitrectomy for stage 4A retinopathy of prematurity in infants with aggressive-posterior ROP: Anatomic and functional results.

Aim: To assess long-term anatomic and functional outcomes of early lens-sparing vitrectomy (LSV) for stage 4A retinopathy of prematurity (ROP) in infants with aggressive-posterior ROP (AP-ROP) which progressed to retinal detachment despite laser treatment.

Methods: Chart review of infants who underwent early 25-gage LSV for stage 4A ROP. Outcomes were anatomic success, mean visual acuity (VA), development of postoperative complications, and refractive changes.

Potential vulnerability of oak forests to climate change-induced flooding: effects of mild oxygen deficiency on Quercus robur and Quercus petraea seedling physiology.

Flooding is characterized by saturation of soil pores with water, leading to hypoxic conditions which affect plant root development and metabolism. We investigated the oxygen deficiency tolerance observed in Quercus robur and Quercus petraea and seek to understand whether it can be explained by enhanced efficiency in oxygen use in the roots, as estimated through radial oxygen loss visualization in relation to growth measurements and root apex respiration. The study showed that root growth, under oxygen deficiency conditions, was significantly reduced only in Q.

Predictive algorithms for early detection of retinopathy of prematurity.

Purpose: To evaluate sensitivity, specificity and the safest cut-offs of three predictive algorithms (WINROP, ROPScore and CHOP ROP) for retinopathy of prematurity (ROP).

Methods: A retrospective study was conducted in three centres from 2012 to 2014; 445 preterms with gestational age (GA) ≤ 30 weeks and/or birthweight (BW) ≤ 1500 g, and additional unstable cases, were included. No-ROP, mild and type 1 ROP were categorized.

Intravitreal bevacizumab for choroidal neovascularization due to pathologic myopia: long-term outcomes.

Purpose: To report the long-term results of anti-vascular endothelial growth factor (VEGF) therapy for choroidal neovascularization (CNV) secondary to pathological myopia (PM).

Methods: Prospective interventional study with extension phase. Eyes affected by CNV due to PM included.
