BACKGROUND The potential exists for laboratory personnel to be exposed to engineered carbon-based nanomaterials (CNMs) in studies aimed at producing conditions similar to those found in natural surface waters [e.g., presence of natural organic matter (NOM)]. OBJECTIVE The goal of this preliminary investigation was to assess the release of CNMs into the laboratory atmosphere during handling an...

Butafenacil is an herbicide that inhibits protoporphyrinogen oxidase (PPOX), an enzyme that catalyzes oxidation of protoporphyrinogen IX to protoporphyrin IX during chlorophyll and heme biosynthesis. Based on a high-content screen, we previously identified butafenacil as a potent inducer of anemia in zebrafish embryos. Therefore, the objective of this study was to begin investigating the utilit...

In two studies, healthy elderly adults were poor at recognizing certain emotions. In study one, an emotion face morphed to express a new emotion. The elderly were impaired when recognizing anger and sadness, whereas no differences were found between the two age groups in recognizing fear or happiness, or in a task requiring reasoning about non=emotion stimuli. In study two, the elderly were imp...

CONTEXT Therapeutic modality control variables are thought to be thermal neutral, a term sometimes used interchangeably with room temperature. We question this common assumption. OBJECTIVE To determine thermal neutrality of common therapeutic modality control variables. DESIGN We performed 5 laboratory experiments, including (1) water temperature over 3 weeks in 3 different containers (glas...

Background: Senna alata belongs to the family, Fabaceae, which is widely distributed in humid and tropical regions of world. It has been ethnobotanically used management diabetes, asthma, typhoid, malaria, worm infestation (ringworms, tinea infections), scabies, skin dermatitis such as eczema, blotch, herpes. Hence, it important quantify pharmacological properties plant, especially infestations...

The lack of access to clean water worldwide and organic, inorganic as well biological contamination existing freshwater sources are a major problem for around 2 billion people, especially in the countries global south. One sign polluted is turbidity. It generally caused by colloidal particulate suspended solids. Chemical flocculants often used reduce turbidity thus eliminate mostly harmful subs...

This study aimed to introduce an alternative, inexpensive, and straightforward polymer with specific mechanical dielectric properties suitable for the fabrication of a clinical-grade kidney phantom. Two polymer-based phantom materials, polydimethylsiloxane (PDMS) silicone elastomer (SE), were investigated their capability meet requirements. The concentration ratios base curing agent (B/C) 9.5/1...

We have recently demonstrated that some forms of cathodal high voltage pulsed current (HVPC) curb posttraumatic edema formation in frog hind limbs. The purpose of this study was to determine, by assessing the capacity of anodal HVPC to curb posttraumatic edema formation, whether polarity is an important variable. Fourteen anesthetized bullfrogs were placed on large dispersive electrodes lining ...

Kiwifruit (Actinidia deliciosa ) were cut into 5 mm slices and placed in polystyrene trays. Various volatile compounds were introduced inside the trays before the lids were covered. The development of decay and the shelf life of the slices were evaluated during storage at 10 8C. Kiwifruit slices treated with 2.24, 11.2, or 22.4 ml l 1 methyl jasmonate maintained good quality after 3 weeks at 10...
