While the Food and Drug Administration (FDA) has had regulatory authority over tobacco products since 2009, public awareness of this authority remains limited. This research examines several broad types of information about FDA tobacco regulatory mission that may improve the perceptions of FDA as a tobacco regulator. Using Amazon Mechanical Turk, 1766 adults, smokers and non-smokers, were randomly assigned to view a statement about FDA regulatory authority that varied three information types in a 2 × 2 × 2 between subjects experimental design: (1) FDA's roles in regulating tobacco (yes/no); (2) The scientific basis of regulations (yes/no); and (3) A potential protective function of regulations (yes/no)...

Acetylcholinesterase inhibitors (AChE-Is) increase both level and duration of action of acetylcholine (ACh); thus, alleviate symptoms of Alzheimer's disease (AD). Glycyrrhizin, is the main active compound in liquorice root. Its aglycone, glycyrrhetinic acid, has shown several beneficial pharmacological activities. This study reports the synthesis and screening of a series of glycyrrhetinic acid analogs as AChE-Is. Fourteen derivatives were prepared, of which five derivatives are recorded as new viz., 3-phenyl-carbamoyl-18β-glycyrrhetinic acid (J9), 3-acetyl-18β-glycyrrhetinic-30-anilinamide (J10), 3-acetyl-18β-glycyrrhetinic-30-ethanolamide (J11), 3-acetyl-18β-glycyrrhetinic-30-n-butylamide (J12) and 18β-glycyrrhetinic acid-30-prenyl ester (J14), in addition to nine known derivatives (J1-J8 & J13)...

Both empirical and theoretical studies, have dealt with the question how to best optimize reproductive fitness for hermaphrodites, using models such as game theory or complicated energetic costs and benefits of mating displays. However, hermaphrodites exhibit a broad spectrum of sexual behaviors like simultaneous, sequential or lifetime gonochorist that cannot be explained using a unique formalism. A possible explanation of this diversity relies on the way these species maximize their fitness: Does the individual hermaphrodite split its time between strategies maximizing its instantaneous reproductive fitness or its evolutionary fitness? Here, we compare these two points of view and extend a game theoretical formalism to a sex allocation model that underlies all sexual behaviors as a result of a dynamic game whose payoff depends on the costs and benefits of sexual reproduction...

Insulin is the paramount anabolic hormone, promoting carbon energy deposition in the body. Its synthesis, quality control, delivery, and action are exquisitely regulated by highly orchestrated intracellular mechanisms in different organs or "stations" of its bodily journey. In this Beyond the Cell review, we focus on these five stages of the journey of insulin through the body and the captivating cell biology that underlies the interaction of insulin with each organ. We first analyze insulin's biosynthesis in and export from the β-cells of the pancreas...

Molecular epidemiological analysis of cryptosporidiosis in Middle Eastern countries suggests that small ruminants could play a major role in the transmission of Cryptosporidium spp. to humans, with a dominance of Cryptosporidium parvum, especially its IId subtypes. However, little information is available on the epidemiology and risk factors of cryptosporidiosis as well the distribution of Cryptosporidium species/genotypes and subtypes in small ruminants in this area, including Kuwait. In the present study, 47 farms from several areas in Kuwait were visited once during October 2014 to September 2015 to collect data on risk factors associated with Cryptosporidium infection...

Nod-like receptor (NLR)X1 is an NLR family protein that localizes to the mitochondrial matrix and modulates reactive oxygen species production, possibly by directly interacting with the electron transport chain. Recent work demonstrated that cells lacking NLRX1 have higher oxygen consumption but lower levels of adenosine triphosphate, suggesting that NLRX1 might prevent uncoupling of oxidative phosphorylation. We therefore hypothesized that NLRX1 might regulate whole-body energy metabolism through its effect on mitochondria...

It is important to estimate the postmortem interval in forensic autopsy. Many methods to estimate the postmortem interval have been reported, and are typically associated with internal examination. However, there are issues such as rejection of autopsy by the family and a lack of forensic doctor in internal examination. Therefore, it is necessary to develop new methods, such as autopsy imaging, that can substitute for internal examination. Here, we first evaluated whether gas volume in the body increased with postmortem interval...

In recent years, an increasing number of studies has investigated majority influence in nonhuman animals. However, due to both terminological and methodological issues, evidence for conformity in nonhuman animals is scarce and controversial. Preliminary evidence suggests that wild birds, wild monkeys, and fish show conformity, that is, forgoing personal information in order to copy the majority. By contrast, chimpanzees seem to lack this tendency. The present study is the first to examine whether dogs (Canis familiaris) show conformity...
