TL;DR: In this article, the Raman and mid-range infrared spectra have been measured on natural limestone and dolomite minerals, and the positions of the wavenumbers are unique for each carbonate mineral and are thus diagnostic of their mineralogy.
Abstract: The Raman and mid-range infrared spectra have been measured on natural limestone and dolomite minerals. The carbonate minerals show four prominent absorption bands in the regions 1450–1420, 890–870, 720–700 and 1000–1100 cm−1. The positions of the wavenumbers are unique for each carbonate mineral and are thus diagnostic of their mineralogy. Calcite and dolomite groups are characterized by the Raman wavenumbers at 288 and 309 cm−1 and the infrared absorption bands at 712 and 728 cm−1, respectively. The principal wavenumber at 1092 cm−1 in the limestone spectra is accompanied by two satellites with values of 1062 and 1075 cm−1. The observed non-split peaks ν2 and ν4 in the infrared spectra of limestone indicate the presence of calcite structure in all these samples. The principal reflections occurring at the d-spacings, 3.03482, 1.91658 and 1.87962 A, confirm the presence of calcite structure in limestone minerals. The principal reflections occurring at the d-spacings, 3.037, 1.79179 and 2.19750 A, confirm the existence of dolomite structure in the dolomite minerals. The calculated lattice parameters for the limestone minerals are: a = 4.9781 A, c = 17.1188 A and V = 367.392(A)3 and the corresponding values for the dolomite minerals are: a = 4.8247 A, c = 15.9868 A and V = 322.28 (A)3.

TL;DR: There is a need for further investigation to isolate active principles which confer the pharmacological action of S. cumini (L.) Skeels (jambolan), as the vast number of literatures found in the database revealed that the extracts of different parts of jambolan showed significant pharmacological actions.
Abstract: Syzygium cumini (S. cumini) (L.) Skeels (jambolan) is one of the widely used medicinal plants in the treatment of various diseases in particular diabetes. The present review has been primed to describe the existing data on the information on botany, phytochemical constituents, traditional uses and pharmacological actions of S. cumini (L.) Skeels (jambolan). Electronic database search was conducted with the search terms of Eugenia jambolana, S. cumini, jambolan, common plum and java plum. The plant has been viewed as an antidiabetic plant since it became commercially available several decades ago. During last four decades, numerous folk medicine and scientific reports on the antidiabetic effects of this plant have been cited in the literature. The plant is rich in compounds containing anthocyanins, glucoside, ellagic acid, isoquercetin, kaemferol and myrecetin. The seeds are claimed to contain alkaloid, jambosine, and glycoside jambolin or antimellin, which halts the diastatic conversion of starch into sugar. The vast number of literatures found in the database revealed that the extracts of different parts of jambolan showed significant pharmacological actions. We suggest that there is a need for further investigation to isolate active principles which confer the pharmacological action. Hence identification of such active compounds is useful for producing safer drugs in the treatment of various ailments including diabetes.

TL;DR: Probiotics revealed greatest effect on the shrimp digestive system particularly in the larval and early post‐larval stages, and stimulate the production of endogenous enzymes in shrimp and contribute with improved the enzyme activities in the gut, as well as disease resistance.
Abstract: Probiotics administration in aquafeed is known to increase feed consumption and absorption due to their capacity to release a wide range of digestive enzymes and nutrients which can participate in digestion process and feed utilization, along with the absorption of diet components led to an increase in host’s health and well‐being. Furthermore, probiotics improve gut maturation, prevention of intestinal disorders, predigestion of antinutrient factors found in the feed ingredients, gut microbiota, disease resistance against pathogens and metabolism. The beneficial immune effects of probiotics are well established in finfish. However, in comparison, similar studies are less abundant in the shellfish. In this review, the discussions will mainly focus on studies reported the last 2 years. In recent studies, native probiotic bacteria were isolated and fed back to their hosts. Although beneficial effects were demonstrated, some studies showed adverse effects when treated with a high concentration. This adverse effect may be due to the imbalance of the gut microbiota caused by the replenished commensal probiotics. Probiotics revealed greatest effect on the shrimp digestive system particularly in the larval and early post‐larval stages, and stimulate the production of endogenous enzymes in shrimp and contribute with improved the enzyme activities in the gut, as well as disease resistance.
