Influences of 23 different equations used to calculate gene copies of SARS-CoV-2 during wastewater-based epidemiology.

Following the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in late 2019, the use of wastewater-based surveillance (WBS) has increased dramatically along with associated infrastructure globally. However, due to the global nature of its application, and various workflow adaptations (e.g.

Pre-treatment of soft drink wastewater with a calcium-modified zeolite to improve electrooxidation of organic matter.

Wastewater from soft drink manufacturing, having a high organic load (chemical oxygen demand (COD) = 4,500 mg L) and high alkalinity (2,653.7 mg L CaCO; pH 12), was pretreated with a calcium-modified zeolite to reduce the alkalinity and improve the electrooxidation of organic matter. The natural zeolite clinoptilolite was modified in various ways with Ca(OH) and CaCl.

DNA Repair Deficient Chinese Hamster Ovary Cells Exhibiting Differential Sensitivity to Charged Particle Radiation under Aerobic and Hypoxic Conditions.

It has been well established that hypoxia significantly increases both cellular and tumor resistance to ionizing radiation. Hypoxia associated radiation resistance has been known for some time but there has been limited success in sensitizing cells to radiation under hypoxic conditions. These studies show that, when irradiated with low linear energy transfer (LET) gamma-rays, poly (ADP-ribose), polymerase (PARP), Fanconi Anemia (FANC), and mutant Chinese Hamster Ovary (CHO) cells respond similarly to the non-homologous end joining (NHEJ) and the homologous recombination (HR) repair mutant CHO cells.

Population and development in the Amazon: A longitudinal study of migrant settlers in the Northern Ecuadorian Amazon.

This paper examines changes over time for a full generation of migrant settlers in the Northern Ecuadorian Amazon (NEA). Data were collected from a 2014 household survey covering a subsample of households surveyed previously in 1990 and 1999. We observed changes in demographic behavior, land use, forest cover, and living conditions.

In vitro screening of radioprotective properties in the novel glucosylated flavonoids.

Novel glucosyl flavonoids are developed by the addition of glucose to naturally occurring flavonoids. Flavonoids are known antioxidants that possess radioprotective properties. In order to investigate the radioprotective properties of novel glucosyl flavonoids, in vitro DNA double-strand breaks (DSBs) analysis was carried out.

Data for induction of cytotoxic response by natural and novel quercetin glycosides.

The flavonoids quercetin, and its natural glycosides isoquercetin and rutin, are phytochemicals commonly consumed in plant-derived foods and used as a food beverage additive. Semi-synthetic maltooligosyl isoquercetin, monoglucosyl rutin and maltooligosyl rutin were developed by synthetic glycosylation to improve their water solubility for food and other applications. Using a system of Chinese hamster ovary (CHO) cells, this study examined the differences in cytotoxic responses induced by short and continuous exposure of natural and synthetic flavonoids.

Antioxidant effects of the VO(IV) hesperidin complex and its role in cancer chemoprevention.

Vanadium compounds are known for a variety of pharmacological properties. Many of them display antitumoral and osteogenic effects in several cell lines. Free radicals induce the development of tumoral processes.
