How Scarification, GA and Graphene Oxide Influence the In Vitro Establishment and Development of Strelitzia.

The propagation of strelitzia plants can be carried out in vitro as an alternative to combine the aseptic conditions of the culture medium with the use of strategies to promote germination and controlled abiotic conditions. However, this technique is still limited by the prolonged time and low percentage of seed germination, which is the most viable explant source, due to dormancy. Thus, the objective of this study was to evaluate the influence of chemical and physical scarification processes of seeds combined with gibberellic acid (GA), as well as the effect of graphene oxide in the in vitro cultivation of strelitzia plants.

An Ultrasonic-Capacitive System for Online Characterization of Fuel Oils in Thermal Power Plants.

This paper presents a ultrasonic-capacitive system for online analysis of the quality of fuel oils (FO), which are widely used to produce electric energy in Thermal Power Plants (TPP) due to their elevated heating value. The heating value, in turn, is linked to the quality of the fuel (i.e.

Evaluation of non-linear models for growth curve in Brazilian tropical goats.

In the present study, 1060 body weight-age records were measured on 300 Canindé goats. The records were collected from Rio Grande do Norte state, North-eastern part of Brazil, and used for evaluation of non-linear models (Brody, Von Bertalanffy, Logistic, and Gompertz) describing growth curve in goats. The non-linear models were compared applying mean squared error of prediction (MSEP), mean squared residue (MSR), mean absolute deviation (MAD), adjusted coefficient of determination (Raj), and convergence percentage (%C) for determining the most appropriate model describing the growth curve in Canindé goats.

Influence of colorful light-emitting diodes on growth, biochemistry, and production of volatile organic compounds in vitro of Lippia filifolia (Verbenaceae).

Lippia filifolia Mart. & Schauer belongs to the Verbenaceae family and it is endemic from the rupestrian fields of the Espinhaço mountain range, located in Minas Gerais, Brazil. It is an aromatic species with medicinal potential due to the production of volatile compounds that constitute its essential oil.

Nitrogen sources and CO concentration synergistically affect the growth and metabolism of tobacco plants.

The initial stimulation of photosynthesis under elevated CO concentrations (eCO) is often followed by a decline in photosynthesis, known as CO acclimation. Changes in N levels under eCO can have different effects in plants fertilized with nitrate (NO) or ammonium (NH) as the N source. NO assimilation consumes approximately 25% of the energy produced by an expanded leaf, whereas NH requires less energy to be incorporated into organic compounds.

The cryoprotectant PVS2 plays a crucial role in germinating Passiflora ligularis embryos after cryopreservation by influencing the mobilization of lipids and the antioxidant metabolism.

Cryopreservation is a process whereby biological structures are preserved in liquid nitrogen (-196 °C) without losing their viability. Many cryopreservation techniques use the Plant Vitrification Solution 2 (PVS2) for cryoprotection. This study will therefore evaluate the influence of different exposure times to the cryoprotectant PVS2 and discuss the importance of the mobilization of reserves and the antioxidant metabolism during the germination of cryopreserved Passiflora ligularis embryos.

In vitro growth of L. affected by silver nanoparticles.

The effect of silver nanoparticles (AgNPs) on plant cells, since their phytotoxicity potential is not yet fully understood. In this context, the aim of the present study was to elucidate the effects of AgNPs in the in vitro culture of . For this purpose, seeds were grown in MS medium supplemented with different concentrations of AgNPs.

Can the Use of a Warm-Air Stream for Solvent Evaporation Lead to a Dangerous Temperature Increase During Dentin Hybridization?

Purpose: To analyze the effect of a warm-air stream for solvent evaporation on the temperature rise in the pulp chamber during dentin hybridization.

Materials And Methods: Dentin disks with thicknesses of 0.5, 1.

Locally adapted Brazilian ewes with different coat colors maintain homeothermy during the year in an equatorial semiarid environment.

The present paper aimed to show the thermoregulatory responses of locally adapted Morada Nova sheep with different coat colors that were exposed to direct solar radiation in an equatorial semiarid region. Animals were classified into four groups according to the coat color as follows: (1) dark red, (2) intermediate red, (3) light red, and (4) white coats. Forty Morada Nova ewes were observed in for 7 consecutive months.

A multivariate approach to the diagnosis of gastrointestinal infection in ewes.

Diagnosing the effects of helminth infections is an efficient way to manage the problem in ruminant production systems. Selection of animals in a flock that are infected with Haemonchus has traditionally involved differential packed cell volume measurements (PCV), and in recent years, the FAMACHA system has been used. However, few small analytical changes have been made.

Performance, endoparasitary control and blood values of ewes locally adapted in semiarid region.

This study evaluated the variation in the prevalence of endoparasitoses and their impact on body condition and blood values of sheep of the Morada Nova breed. A total of 138 ewes were examined for their morphology (body weight, BW; body condition score, BCS), parasitology (faecal egg count, FEC; Famacha© score; coproculture), hematology (red blood cell count,RBC); hemoglobin concentration, HE; packet cell volume, PCV; mean corpuscular volume, MCV,; mean corpuscular hemoglobin, MCH; mean corpuscular hemoglobin concentration, MCHC; leukocytes, WBC) and serum biochemistry (glucose, cholesterol, triglycerides, urea, creatinine, total protein, albumin, globulin, AST and ALT). Overall the animals presented higher BW and BCS in the months of September and December, however, with high FEC, in addition to a large number of animals with Famacha score 4 and 5.

Anti-inflammatory effect of extract and fractions from the leaves of Byrsonima intermedia A. Juss. in rats.

Aim Of The Study: Byrsonima intermedia is commonly used for its antiseptic, antimicrobial, and anti-inflammatory properties in the treatment of diarrhea and dysentery in Brazilian folk medicine. The purpose of this study was to examine the anti-inflammatory activity of the aqueous extract and fractions of Byrsonima intermedia leaves.

Materials And Methods: Rats with carrageenan-induced paw edema and fibrovascular tissue growth, which was induced by subcutaneous implantation of a cotton pellet, were used as acute and chronic animal models of inflammation to investigate the anti-inflammatory effects of the aqueous extract and the individual ethyl acetate (EtOAc) and aqueous fractions of Byrsonima intermedia and catechin.
