Examinamos las tendencias emergentes del liderazgo transformacional y su aplicación en la gobernanza Sudamérica. El objetivo general fue determinar sobre para gobernabilidad Sudamérica 2020-2024. Se planteó como objetivos específicos: Analizar cuál es tendencia de los liderazgos Sudamérica, identificar casos exitosos describir cómo este tipo líder podría influir gobernanza. Concluyendo que: Las están marcadas por líderes carismáticos populistas movilizando apoyo político, demanda políticas...
Vitamin A (VA) has a key role in vertebrate morphogenesis, determining body patterning and growth through the control of cell proliferation differentiation processes. VA regulates primary molecular pathways those processes by binding its active metabolite (retinoic acid) to two types specific nuclear receptors: retinoic acid receptors (RARs) retinoid X (RXRs), which promote transcription downstream target genes. This process is well known most higher vertebrates; however, scarce information...
Abstract The ability of zebrafish to fully regenerate its caudal fin has been explored better understand the mechanisms underlying de novo bone formation and develop screening methods towards discovery compounds with therapeutic potential. Quantifying regeneration largely depends on successfully measuring new tissue through that require optimization standardization. Here, we present an improved methodology characterize analyse overall in adult zebrafish. First, regenerated mineralized areas...
We used RNA probes and enzyme activities to compare the cellulolytic microbial ecosystems of rumen cecum. Four rumen- cecum-cannulated wethers were fed a diet barley plus hay (60:40). Digesta samples collected 1 h before feeding 3, 6, 9 after for measurements on populations, 3 6 digestion measurements, pH, VFA. Polysaccharidase glycosidase specific solid-adherent microorganisms measured respectively by amount reducing sugars released from xylan or avicel p-nitrophenol derivatives xylose...
In bay snook (Petenia splendida) larvae the histological development of digestive system and swim bladder, their relative timing differentiation were studied from hatching to 45 days post-hatch (dph) at 29°C. Newly hatched showed a simple tract, which appeared as straight undifferentiated tube lined by single layer columnar epithelial cells (future enterocytes). The anatomical tract accessory glands was very intense, asynchronous process, proceeding distal anterior part. intestine first...
Abstract Catfish (Siluriformes) are important species for aquaculture worldwide, with an annual production in 2018 of ca . 6 million t. This review focuses on reassessing larval development, first feeding, and early rearing practices the most farmed catfish species, along some candidate diversification: Pangasianodon hypophthalmus (Pangasiidae), Clarias gariepinus (Clariidae), Ictalurus punctatus (Ictaluridae), Pseudoplatystoma spp. (Pimelodidae), Heteropneustes fossilis (Heteropneustidae),...
The effects of prolonged feed deprivation (40 days at 18° C) and re‐feeding (30 days) on body mass, growth the activity selected pancreatic intestinal enzymes were evaluated in migrating European glass eels Anguilla anguilla by comparison with a control group fed to satiation hake Merluccius merluccius roe for duration experiment. Feed resulted mass loss reduction digestive function, as revealed decrease total specific activities (trypsin α ‐amylase) brush border (alkaline phosphatase...
Several studies have evaluated the effects of dietary vitamin A (VA) on incidence skeletal deformities during early ontogeny fish, but little is known about its bones depending their process ossification (dermal or chondral). We examined along development (30 and 48 dph) by double staining technique, in dermal (haemal caudal vertebral bodies) chondral (neural haemal spines, epural, parahypural hypurals) Senegal sole post metamorphosed larvae fed with different VA levels (37 000, 44 666, 82...
Abnormal pigmentation of Senegalese sole has been described as one problem facing the full exploitation its commercial production. To improve our understanding flatfish this commercially important species we have evaluated eleven genes related to two different processes pigmentation: melanophore differentiation, and melanin The temporal distribution gene expression peaks corresponds well with changes in patterns intensity skin melanization. Several ratios were also examined put perspective...

Abstract Temperature has a key impact on the physiology, food acquisition, metabolic rate, growth, and reproduction of organisms. Thus, exploring effects climate change species physiology is important for conservation management native non‐native bivalve species. In this work, an integrative laboratory approach was used to compare physiological, cellular, molecular responses Unio delphinus invasive Corbicula fluminea under natural heat‐wave event. Whereas filtration rate in C. clearly...
Kisspeptin regulates puberty and reproduction onset, acting upstream of the brain–pituitary–gonad (HPG) axis. This study aimed to test a kisspeptin-based hormonal therapy on cultured Senegalese sole (G1) breeders, known have reproductive dysfunctions. A single intramuscular injection KISS2-10 decapeptide (250 µg/kg) was tested in females males during season, gonad maturation, sperm motility, plasma levels gonadotropins (Fsh Lh) sex steroids (11-ketotestosterone, testosterone estradiol), as...
Global aquaculture growth will most probably face specific conditions derived from climate change. In fact, the severe impacts of these changes be suffered by aquatic populations in restrictive circumstances, such as current locations, which represent a perfect model to study global warming effects. Although impact temperature on fish reproduction has been characterized many aspects, this was focused recreating more realistic models warming, particularly considering heatwave phenomena, order...
