Malpighiaceae constitutes a family of 77 genera and ca. 1300 species, distributed in tropical and subtropical regions of both hemispheres. They are mainly diversified in the American continent and distributed in a wide range of habitats and altitudinal gradients. For this reason, this family can be a model plant group to ecological and biogeographical analyses, as well as evolutive studies. In this context, an analysis of distribution, richness, endemism and phylogenetic diversity of Malpighiaceae in natural regions and their altitudinal gradients was undertaken. Malpighiaceae are represented in Colombia by 34 genera and 246 species (19.1% of endemism). Thus, Colombia and Brazil (44 genera, 584 species, 61% of endemism) are the two richest countries on species of this family. The highest species richness and endemism in Colombia is found in the lowlands (0-500 m a.s.l.: 212 species, 28 endemics); only ten species are distributed on highlands (2500-3200 m a.s.l.). Of the Malpighiaceae species in Colombia, Heteropterys leona and Stigmaphyllon bannisterioides have a disjunct amphi-Atlantic distribution, and six other species show intra-American disjunctions. Both richness and endemism decrease with altitude (y = -0.061x + 173.57; R2 = 0.82; y = -0.009x + 27.76; R2 = 0.95, respectively). Amazonia (116 species, 4 endemics) and the Andes (89 species, 23 endemics) exhibit the highest richness among the family. In Colombia, 15 of the 19 clades among the family are represented, where the most diversified are the Stigmaphyllon clade (5 genera, 48 species, 10 endemics), the Byrsonima clade (3/39/5) and the Hiraea clade (3/31/9). The relationship of phylogenetic diversity with altitude is similar to the pattern of specific richness by altitudinal interval. Amazonia, Orinoquia, and Magdalena Valley show highest phylogenetic diversity. These results, combined with those of other highly diversified biological groups in the country, could be important to define and delimitate new priority areas for conservation in Colombia.

Lycopene is a well-known compound found commonly in tomatoes which brings wide range of health benefits against cardiovascular diseases and cancers. From an anti-cancer perspective, lycopene is often associated with reduced risk of prostate cancer and people often look for it as a dietary supplement which may help to prevent cancer. Previous scientific evidence exhibited that the anti-cancer activity of lycopene relies on its ability to suppress oncogene expressions and induce proapoptotic pathways. To further explore the real potential of lycopene in cancer prevention, this review discusses the new insights and perspectives on the anti-cancer activities of lycopene which could help to drive new direction for research. The relationship between inflammation and cancer is being highlighted, whereby lycopene suppresses cancer via resolution of inflammation are also discussed herein. The immune system was found to be a part of the anti-cancer system of lycopene as it modulates immune cells to suppress tumor growth and progression. Lycopene, which is under the family of carotenoids, was found to play special role in suppressing lung cancer.

Many of Bunda's Tourism Diploma graduates are still unemployed because some are less interested in becoming self-employed. It because students are not motivated to become entrepreneurs, and the family environment is not yet supported. This study aimed to measure: the relationship between entrepreneurial learning outcomes, entrepreneurial motivation, and family environment with interest in entrepreneurship. This type of research is descriptive correlational. This research population is all students of the Hospitality study program of the Bunda Padang Tourism Academy, batch 2017 and 2018, totaling 61 students. The sample in this study were 61 students using the total sampling technique. The data collection instrument used a questionnaire using a Likert scale and data analysis methods, including simple correlation and multiple correlations. Research is expected to increase students' entrepreneurial knowledge through attitudes, knowledge, and skills to overcome entrepreneurial tasks' complexity, providing real experiences for students to carry out entrepreneurial practices.

A family consisting of a mother and father, heterozygous for idiopathic hyperlipemia, and their four offspring, one heterozygous and three homozygous for the disease, are described. In addition, a fifth child who is heterozygous, born of same mother but by another incompletely studied father, is presented. The genetics of the disease in this family, and also in the general population, with emphasis on diagnosis and prognosis in heterozygotes is discussed. The interrelationship of various lipid components in serum and their metabolism are briefly reviewed. The possible defective mechanisms in hyperlipemia, the techniques for deciding on the specific defect, and their application to the members of this family are reviewed. The effect of heparin, nicotinic acid, and fat-free diets in the homozygous members of the family are evaluated and their therapeutic applications are discussed. The symptomatology, possible pathologic physiology, relationship to lipid levels in serum and occurrence of abdominal crises in some of the homozygous members of this family are pointed out. The relationship of cholesterol and triglyceride levels in serum to, and the significance of, idiopathic hyperlipemia in the genesis of, atherosclerosis and coronary artery disease is elucidated.

Regulation of feeding is a fundamental element of homeostasis. This is reflected in the similarity of control mechanisms in a wide range of animals, including insects and humans. A close examination of feeding behavior can illuminate the physiological processes driving regulation. A simple, inexpensive method for recording fine details of feeding by caterpillars is described. Possible experiments, interpretation of the data, and the relationship of observations to the underlying physiology, are outlined.

Recent experimental work has indicated that species of Archigetes are capable of infecting and maturing in fishes in addition to tubificids.The genus Archigetes is re-defined on the basis of morphological and biological characters, with particular emphasis on recent life history studies. All species capable of neotenic development have been re-united in a single genus.A description of all species of Archigetes together with a key for their identification are included. New synonomies are discussed.The relationship of Archigetes to other genera of the family is briefly considered, and it is concluded that it forms the terminal stage in a series showing the attainment of neotenic development.I wish to thank Professor R. J. Pumphrey in whose Department the work was carried out, and Dr J. C. Chubb for advice and help in the preparation of this manuscript. I am also grateful to Professor K. Berg and Dr R. L. Calentine for the loan of specimens. The work was carried out during the tenure of a Nature Conservancy Research Studentship.

Part I. The Medulla Oblongata, And Its Variations Acoording To Diet And Feeding Habits In previous communications to this Society the relationship of the habits of feeding and diet to the form and pattern of the medulla oblongata has been described in the cyprinoids, clupeids, and gadoids (Evans, 1931, 1932, 1935). This research takes up a similar study of the brain of the Pleuronectidae. The expense has been borne by a grant from the Royal Society for which the author tenders his grateful thanks. It has seemed to be desirable to extend the observations to the fore- and mid-brain, as in some members of the family these present a very marked development. In order to elucidate some of the problems that arise I have also studied the brain of the eel, and some interesting conclusions have resulted. We find, as a result of examination by the naked eye and of serial sections, that we can divide the following species into four groups as follows: I. The sole, Solea vulgaris .

The authors examined the relationship of two dimensions of the theory of social development—vulnerability (predictors, risk factors) and protectivity—in two samples, schoolchildren aged ten to fifteen years and addictive drug users. On the basis of the Hirschi model of protective factors, they found that the most important protective factors (attachment, commitment, involvement, belief) act against substance use. A surprising finding was that among the predictors of the addicts some forms of escape from the family act against the development of drug use, that is, they can be regarded as a protective predictor. The findings of the study draw attention to the complexity of the vulnerability-protectivity relationship and to the need for further research.
