Optical Insight: Spectrophotometry as a Tool to Quantify Cell Density of Green Microalgae in Suspension, with Emphasis on Growing Conditions and Toxicological Evaluations.

Microalgae are often used in different industrial sectors and can be used as indicators of aquatic environmental health. An essential step for cultivating microalgae is assessing the cell density, which is traditionally performed through cell counting by optical microscopy (OM). However, this method has limitations, mainly in terms of runtime and low reproducibility.

Synanthropic Rodents as Bioindicator of Human Pathogens in a Tourist Area of Brazil.

The black rat Rattus rattus is an exotic and synanthropic rodent prominent in Brazil and with high adaptation to urban areas. The species have an omnivorous diet feed on human food resources, potentially becoming infected and spreading infectious agents that cause zoonoses such as leptospirosis, leishmaniosis, Chagas disease, and toxoplasmosis, which are significant public health concerns in the country. We analyzed the epidemiologic profile of R.

Effects of tropical fruit blends on fermentative and pigmentation aspects of probiotic native cultured goat milk.

Background: Fruits are sources of bioactive compounds such as phenolics that bring health benefits to consumers. The addition of fruit products and microorganisms with probiotic potential in fermented goat milk can facilitate the acquisition of these benefits through diet. In this sense, the objective of this study was to evaluate the effect of incorporating a mixture of ingredients from jaboticaba (), jambolana (), and mandacaru () fruits on fermentation parameters (pH, titratable acidity, viability of the native culture CNPC003 and the starter culture), associated with pigmentation (phenolic compound content and color) through experimental mixture design.

Intravenous meropenem and intraperitoneal use of 10% aqueous extract of Schinus terebinthifolius Raddi (Anacardiaceae) in elderly rats after induction of autogenous fecal peritonitis.

Purpose: To evaluate intravenous meropenem and intraperitoneal 10% aqueous extract of Schinus terebinthifolius (aroeira) in elderly rats after autogenous fecal peritonitis.

Methods: Thirty 18-month-old Wistar rats underwent peritonitis with 4 mL/kg of autogenous fecal solution. They were stratified into groups: control without treatment; study I, treated with meropenem (40 mg/kg); and study II, treated with meropenem at the same dose and intraperitoneal 10% aqueous extract of aroeira.
