Evolution from the first life on earth to humans took ~3.8 billion years. During the time there have been countless struggles among the species. Mycobacterium tuberculosis was the last major uncontrollable species against the human public health worldwide. After the victory with antibiotics, cancer has become the leading cause of death since 1981 in Japan. Considering that life inevitably depends on ceaseless electron transfers through iron and oxygen, we believe that carcinogenesis is intrinsically unavoidable side effects of using iron and oxygen. Many animal models unequivocally revealed that excess iron is a risk for carcinogenesis. This is supported by a variety of human epidemiological data on cancer risk and prognosis. Cancer is basically a disease of the genome with persistently activated oncogenes and inactivated tumor suppressor genes through which iron addiction with ferroptosis-resistance is maintained. Engineering has made a great advance in the past 50 years. In particular, nanotechnology is distinct in that the size of the engineered molecules is similar to that of our biomolecules. While some nano-molecules are found carcinogenic, there are principles to avoid such carcinogenicity with a smart possibility to use nano-molecules to specifically kill cancer cells. Non-thermal plasma is another modality to fight against cancer.

Abstract Gas Assisted Etching (GAE) is the enabling technology for High Aspect Ratio (HAR) circuit access via milling in Focused Ion Beam (FIB) circuit modification. Metal interconnect layers of microelectronic Integrated Circuits (ICs) are separated by Inter-Layer Dielectric (ILD) materials, therefore HAR vias are typically milled in dielectrics. Most of the etching precursor gases presently available for GAE of dielectrics on commercial FIB systems, such as XeF2, Cl2, etc., are also effective etch enhancers for either Si, or/and some of the metals used in ICs. Therefore use of these precursors for via milling in dielectrics may lead to unwanted side effects, especially in a backside circuit edit approach. Making contacts to the polysilicon lines with traditional GAE precursors could also be difficult, if not impossible. Some of these precursors have a tendency to produce isotropic vias, especially in Si. It has been proposed in the past to use fluorocarbon gases as precursors for the FIB milling of dielectrics. Preliminary experimental evaluation of Trifluoroacetic (Perfluoroacetic) Acid (TFA, CF3COOH) as a possible etching precursor for the HAR via milling in the application to FIB modification of ICs demonstrated that highly enhanced anisotropic milling of SiO2 in HAR vias is possible. A via with 9:1 aspect ratio was milled with accurate endpoint on Si and without apparent damage to the underlying Si substrate.

In the past few years, several biased ligands acting at the mu-opioid receptor were reported in the literature. These agonists are aimed at reducing pain while having fewer side effects than morphine, the gold standard of opioid analgesics. In this mini-review, we describe and discuss the recent advances in mu-biased ligands actually in preclinical and clinical development stages, including the latest U.S. Food and Drug Administration review of oliceridine, a biased mu-agonist for moderate to severe acute pain treatment developed by the company Trevena.

Basic Features

THE ORIGINS and adaptive significance of music, long an elusive target, are now active topics of empirical study, with many interesting developments over the past few years. This article reviews research in anthropology, ethnomusicology, developmental and comparative psychology, neuropsychology, and neurophysiology that bears on questions concerning the origins and evolution of music. We focus on the hypothesis that music perception is constrained by innate, possibly human- and musicspecific principles of organization, as these are candidates for evolutionary explanations. We begin by discussing the distinct roles of different fields of inquiry in constraining claims about innateness and adaptation, and then proceed to review the available evidence. Although research on many of these topics is still in its infancy, at present there is converging evidence that a few basic features of music (relative pitch, the importance of the octave, intervals with simple ratios, tonality, and perhaps elementary musical preferences) are determined in part by innate constraints. At present, it is unclear how many of these constraints are uniquely human and specific to music. Many, however, are unlikely to be adaptations for music, but rather are probably side effects of more general-purpose mechanisms. We conclude by reiterating the significance of identifying processes that are innate, unique to humans, and specific to music, and highlight several possible directions for future research.

Anticancer Treatment

Lung cancer remains to be one of the most common and serious types of cancer worldwide. While treatment is available, the survival rate of this cancer is still critically low due to late stage diagnosis and high frequency of drug resistance, thus highlighting the pressing need for a greater understanding of the molecular mechanisms involved in lung carcinogenesis. Studies in the past years have evidenced that microRNAs (miRNAs) are critical players in the regulation of various biological functions, including apoptosis, which is a process frequently evaded in cancer progression. Recently, miRNAs were demonstrated to possess proapoptotic or antiapoptotic abilities through the targeting of oncogenes or tumor suppressor genes. This review examines the involvement of miRNAs in the apoptotic process of lung cancer and will also touch on the promising evidence supporting the role of miRNAs in regulating sensitivity to anticancer treatment.

Abstract Medication management is an ongoing consideration for adults ages 85 and older, their caregivers, and healthcare providers. When asked about their attitudes and behaviors regarding medication management, over 73% of the Lifestyle Leaders reported taking 3+ prescription medications daily and managing their own medication regimes. 61.9% of participants had taken over-the-counter, non-prescription medication for pain over the past five years. When asked why some participants didn’t currently take prescription medications to manage pain, the most frequently-reported responses were: “I don’t feel that my pain warrants a prescription medication,” (19%, n=8), “I don’t want to deal with the side effects,” and “I don’t trust drug companies,” (9.5%, n=4, respectively). The Lifestyle Leaders reported they would be most likely to go to the internet (over their local pharmacist) to ask for advice about their medication(s). Meanwhile, 39% of Lifestyle Leaders would trust a robot to manage their medication(s) for them.

Clinical Action

The tricyclic antidepressants (TCAs) were discovered accidentally by pharmaceutical chemists seeking first, better antihistamines and then antipsychotic agents. Careful clinical assessment revealed the antidepressant properties and suggested that the closer the patient resembled the classical textbook description of ‘endogenous’ depression, the more likely was an adequate clinical response to occur (Kuhn, 1958). However, it was quickly realised that the TCAs possess a plethora of side-effects, particularly sedation and symptoms related to their anticholinergic effects.Despite much research over the past 25 years, it is unclear how TCAs effect clinical improvement. The two main neurotransmitters involved in some way are noradrenaline (Schildkraut, 1965) and 5-hydroxytryptamine (5-HT; serotonin; Van Praag, 1977). It was proposed that TCAs acted by blocking the reuptake of one or other or both of these neurotransmitters, thereby increasing their concentration in the synaptic cleft. However, as well as these acute effects, chronic effects, such as a decrease in the number of central beta-adrenoceptors (‘down-regulation’) occur, and these are probably more relevant to the clinical action.

Leishmaniasis is considered as an important health problem in the world. Cutaneous Leishmaniasis is epidemic in all of places of Iran, this disease begins as small swells and then they gradually grow and turn into wounds. Since the epidemiological study of this problem is effective in preventing and controlling it. The current research was conducted to study the epidemiological study of Cutaneous Leishmaniasis in Yazd province during the past 5(2014-2018) years. This cross-sectional study has been conducted on registered information and documents of the patients having problem in Yazd province remedial and health care centers over the past 5 years. First, the registered demographic and epidemiological data of the patients were extracted and then they were analyzed by using SPSS 18 software with chi-square test and descriptive statistics.897 patients included 457 males (51.06%) and 439 females (48.94%). The majority of the patients were between nine 20-29 years old and the minority of them were over the range of 5-9 years old. Most lesions were on the hand and leg of the patients. It was also found that there was a significant relationship between age groups and types of Leishmaniasis (P<0.05) as well as gender and type Leishmaniasis (P<0.05). According to our study, there has been an ascending trend in disease frequency in Yazd province from 2014 to 2018. This increase in diseases due to lack of health and educational status of the people-is also a lack of personal hygiene.

Mistaken Identification

The remarkable “evolution” of the reconstructions of Anomalocaris, the extraordinary predator from the 515 million year old Middle Cambrian Burgess Shale of British Columbia, reflects the dramatic changes in our interpretation of early animal life on Earth over the past 100 years. Beginning in 1892 with a claw identified as the abdomen and tail of a phyllocarid crustacean, parts of Anomalocaris have been described variously as a jellyfish, a sea-cucumber, a polychaete worm, a composite of a jellyfish and sponge, or have been attached to other arthropods as appendages. Charles D. Walcott collected complete specimens of Anomalocaris nathorsti between 1911 and 1917, and a Geological Survey of Canada party collected an almost complete specimen of Anomalocaris canadensis in 1966 or 1967, but neither species was adequately described until 1985. At that time they were interpreted by Whittington and Briggs to be representatives of “a hitherto unknown phylum.”Here, using recently collected specimens, the two species are newly reconstructed and described in the genera Anomalocaris and Laggania, and interpreted to be members of an extinct arthropod class, Dinocarida, and order Radiodonta, new to science. The long history of inaccurate reconstruction and mistaken identification of Anomalocaris and Laggania exemplifies our great difficulty in visualizing and classifying, from fossil remains, the many Cambrian animals with no apparent living descendants.

This chapter uses the Iran and Russia cases to understand how modern U.S. financial sanctions operate (including how they interact with traditional tools of foreign policy) and how to better incorporate them into the United States’ standing arsenal of foreign policy tools. It does so by considering three broad sets of questions: First, how has the use of financial sanctions evolved over the past fifteen years? Second, what are the main ways in which financial sanctions impose costs on sanctioned countries? Finally, how should U.S. policymakers alter the use of financial sanctions to maximize their impact, sustain their strength, and minimize problematic side effects?

Life On Earth

Life on earth has evolved during the past several billion years under relatively bright days and dark night conditions. The wide-spread adoption of electric lights during the past century exposed animals, both human and non-human, to significant light at night for the first time in their evolutionary history. Endogenous circadian clocks depend on light to entrain to the external daily environment and seasonal rhythms depend on clear nightly melatonin signals to assess time of year. Thus, light at night can derange temporal adaptations. Indeed, disruption of naturally evolved light–dark cycles results in several physiological and behavioural changes with potentially serious implications for physiology, behaviour and mood. In this review, data from night-shift workers on their elevated risk for metabolic disorders, as well as data from animal studies will be discussed. Night-shift workers are predisposed to obesity and dysregulated metabolism that may result from disrupted circadian rhythms. Although studies in human subjects are correlative, animal studies have revealed several mechanisms through which light at night may exert its effects on metabolism by disrupting circadian rhythms that are associated with inflammation, both in the brain and in the periphery. Disruption of the typical timing of food intake is a key effect of light at night and subsequent metabolic dysregulation. Strategies to avoid the effects of light at night on body mass dysregulation should be pursued.
