Hydrothermal extraction of dietary fiber from pearl millet bran: optimization, physico-chemical, structural and functional characterization.

Pearl millet bran is rich source of dietary fiber and several other bioactive compounds and is an unexploited by-product of millet processing industries. The utilization of pearl millet bran for extraction of dietary fiber can be an effective method for its valorization. Hydrothermal extraction of dietary fiber from pearl millet bran is a simple eco-friendly technique in terms of minimal consumption of toxic solvents, increased extraction yield, high purity and considered as an economically viable technique. In the present investigation, extraction and optimization of dietary fiber from pearl millet bran was performed using hydrothermal technique. The highest yield of dietary fiber (74.5%, w/w) was obtained under optimized conditions of water to solid ratio (20:1), temperature (90 °C) and time (15 min). The extracted dietary fiber from pearl millet bran was further assessed for its physico-chemical, functional and structural properties. The studies of functional and physico-chemical properties presented the water holding capacity (6.50 g/g and 3.99 g/g), swelling power (2.0 g/g and 2.05 g/g), oil holding capacity (4.91 g/g and 2.42 g/g), solubility (70%), total phenolic content of 4.24 mg GAE/g and 4.32 mg GAE/g, DPPH reduction of 86.6% and 83.9%, respectively. The results indicated that pearl millet bran can act as rich source of dietary fiber with health enhancing properties and can be utilized as potential food component in preparation of functional food products.

The outcome of isolated primary fetal hydrothorax: a 10-year review from a tertiary center.

INTRODUCTION: The management of primary fetal pleural effusion remains a challenge for clinicians given the paucity of clinical information to guide practice. MATERIALS AND METHODS: A retrospective descriptive study of cases referred for management to our fetal therapy center over a 10-year period. Survival to hospital discharge was evaluated against case characteristics and prenatal intervention. For this study, we categorized the severity of the pleural effusion at diagnosis as mild, moderate or severe, and the clinical course as regression, stable or progression. RESULTS: Forty-five of the 103 pregnancies complicated by fetal pleural effusions during the study period were managed for primary effusions. Termination of pregnancy was requested in 6 cases. Thirty-nine pregnancies continued management, with 14 undergoing prenatal intervention. The overall survival rate to hospital discharge was 51%, including 7 survivors after prenatal intervention. The rate of survival was low if the effusion was categorized as severe at diagnosis or if there was progression of the clinical course. CONCLUSIONS: Case characteristics at the time of diagnosis and clinical course can be used to guide patient counseling and decision-making regarding fetal therapy. Prenatal intervention may improve the chance of survival in cases with characteristics associated with a poor prognosis.

The common molecular players in plant hormone crosstalk and signaling.

Plant growth and development is under the control of mutual interactions among plant hormones. The five classical categories of plant hormones include auxins, cytokinins, gibberellins, abscisic acid and ethylene. Additionally, newer classes of plant hormones have been recognized like brassinosteroids, jasmonic acid, salicylic acid and polyamines. These hormones play significant roles in regulating the plant growth and development. Various receptors and key signaling components of these hormones have been studied and identified. At genetic level, crosstalk among the various plant hormones is found to be antagonistic or synergistic. In addition, components of signaling pathway of one plant hormone interact with the signaling components of other hormone. Thus, an attempt has been made to review the literature regarding the role of plant hormones in plant physiology and the common molecular players in their signaling and crosstalk.
