Pb (II) detection and versatile bio-imaging of green-emitting carbon dots with excellent stability and bright fluorescence

Green-emitting carbon dots (G-CDs) were synthesized by simple and green hydrothermal method using betaine hydrochloride and sulfadiazine as carbon and nitrogen sources. Excellent luminescence stability with various pH, salt concentrations,...

Thermoregulatory, growth and blood indices of broiler chicks fed betaine hydrochloride supplemented diets under high ambient temperature

The study was carried out to determine the effect of dietary inclusion of Betaine Hydrochloride on the thermoregulatory, growth, haematological and serum biochemical indices of broiler chicks under high ambient temperature because Betaine is a organic osmolyte that can protect the birds from oxidative stress. Betaine Hydrochloride was included at 0, 1.5, 3 and 4.5 g/kg feed, respectively. One hundred and eighty, one day old Hubbard broiler chicks were allotted into four treatments with three replicates each in a completely randomized design (CRD). There were no differences (p>0.05) in the rectal temperature and heart rate across the treatments. Chicks fed 1.5 and 4.5 g/kg diet Betaine Hydrochloride had better (p>0.05) feed intake, weight gain and feed conversion ratio than birds fed control and 3 g/kg diet Betaine hydrochloride. Haematological and serum biochemical indices were similar (p>0.05) across the treatments. Betaine hydrochloride can be included in the diets of broiler chicks up to 4 g/kg diet to improve growth performance without any detrimental effect on growth, haematological and serum biochemicals.

Betaine Hydrochloride Treatment Affects Growth and Phenylpropanoid Accumulation in Tartary Buckwheat (Fagopyrum tataricum) Seedlings under Salt Stress

Betaine is one of the most competitive compounds that accumulate in different cellular compartments to adjust osmotic balance. Among the various stressors, salinity stress often leads to osmotic and ionic stress in plants, either increasing or decreasing certain secondary plant metabolites. In this study, different concentrations of NaCl, betaine, and combined NaCl and betaine were used in time-course experiments to investigate growth pattern variation and accumulation of phenylpropanoid compounds in buckwheat sprouts. A significant increase in growth was observed with the application of 0.1–1.0 mM betaine. Although overall, the total phenylpropanoid compounds were lower compared to the control, the sole application of 50 mM NaCl and 1.0 mM betaine especially enhanced the accumulation of some of these compounds in comparison to others. Betaine application at lower concentrations was found to enhance the growth of buckwheat sprouts slightly. The results of this study show that phenylpropanoid content did not increase significantly in any of the treatments. However, it was proven that the phenylpropanoid biosynthetic pathway is stimulated under abiotic stress, resulting in a higher accumulation of various phenylpropanoid compounds. This suggests that the level of accumulation of phenylpropanoid compounds due to abiotic stress may be species-dependent.
