Expression of and Rooting Response in Chestnut Leaves Are Dependent on the Auxin Polar Transport and the Ontogenetic Origin of the Tissues.

The mechanisms underlying the de novo regeneration of adventitious roots are still poorly understood, particularly in trees. We developed a system for studying adventitious rooting (AR) at physiological and molecular levels using leaves excised from chestnut microshoots of the same genotype but with two distinct ontogenetic origins that differ in rooting competence. Leaves were treated with auxin and N-1-naphthyl-phthalamic acid (NPA), an inhibitor of auxin polar transport (PAT).

Cationic Pollutant Removal from Aqueous Solution Using Reduced Graphene Oxide.

Reduced graphene oxide (rGO) is one of the most well-known graphene derivatives, which, due to its outstanding physical and chemical properties as well as its oxygen content, has been used for wastewater treatment technologies. Particularly, extra functionalized rGO is widely preferred for treating wastewater containing dyes or heavy metals. Nevertheless, the use of non-extra functionalized (pristine) rGO for the removal of cationic pollutants is not explored in detail or is ambiguous.

Cleft Lip and Palate Midfacial Hypoplasia: Criteria to Choose the Treatment.

A series of skeletal and dentoalveolar/occlusal criteria were proposed for choosing the treatment modality for the management of midface hypoplasia in cleft lip/palate patients, focusing on functional improvement, aesthetics, and minimizing the risk of recurrence and secondary alterations. For which, 42 patients with nonsyndromic cleft lip/palate, all with previous primary lip/palate surgeries and without previous osteotomies, were analyzed. Orthognathic surgery (OS) (n = 24) and maxillary distraction osteogenesis (n = 18) with anterior segmental osteotomies (segmental distraction osteogenesis [SD]), alveolar transport disc (TD), and midface total distraction osteogenesis (TDO) by modified Le Fort III osteotomy was done.

Nutrient Incorporation in First Feeding Seahorses Evidenced by Stable Carbon Isotopes.

Nutritional issues are among the most critical factors in the initial survival of juvenile seahorses. Currently, there is a knowledge gap on the relationship between nutrient assimilation and the effects on initial mortalities and growth. In the present study, the stable isotope approach was used to assess the incorporation of two live preys ( and copepods) in juvenile seahorses .
