BMC Health Services Research , 2006, DOI: 10.1186/1472-6963-6-51
Abstract: Strict and controlled application of existing clinical decision trees in a sample of rural health centres allowed the estimation of the corresponding need for and characteristics of curative referrals in rural Niger. Compliance of referral was monitored as well. Need was matched against actual referral in 11 rural districts. The referral patterns were registered so as to get an idea on the types of pathology referred.The referral rate benchmark was set at 2.5 % of patients consulting at the health centre for curative reasons. Niger's rural districts have a referral rate of less than half this benchmark. Acceptability of referrals is low for the population and is adding to the deficient referral system in Niger. Mortality because of under-referral is highest among young children.Referral patterns show that the present programme approach to deliver health care leaves a large amount of unmet need for which only comprehensive first and second line health services can provide a proper answer. On the other hand, the benchmark suggests that well functioning health centres can take care of the vast majority of problems patients present with.Referral is the weak link in the organisation of many district health systems in rural Africa. In theory health centres and district hospitals should complement each other: whoever can be treated adequately at health centre level will be treated there, and the referral system will ensure that all others are referred to the district hospital in a timely fashion [1-6]. The criteria for referral are supposed to be purely medical, and objective, in the interest of the patient. This appears straightforward, but everything indicates that referral systems are usually dysfunctional [7-9]. Studies on maternal health in particular readily blame inadequate referral systems [10-19].In urban areas often many false positive referrals are observed: pressured by patients, nurses at the first contact level readily refer a majority of patients to overcrow
Love Is the Cause of Human Evolution  [PDF]
Enrique Burunat
Advances in Anthropology (AA) , 2014, DOI: 10.4236/aa.2014.42013
Abstract:

Ever since the publication of “The Origin of Species by Means of Natural Selection” by Charles Darwin in 1859, many theories have been put forward regarding the reasons as to why animals and humans are different. Whilst there was an initial tendency to focus on the differences apparent in the main anatomic characteristics of the human body, in more recent time research has concentrated on differences that are evident both in the anatomy and in that of the workings of the human brain. While in the past, the essence of the human being was placed on the pelvic structure, the creation of tools or even the intermaxillary bone, the introduction of new technology and cerebral imaging is enabling us to glean previously unthinkable information regarding the evolution of specific structures and parts of the brain. All these discoveries can be associated with new theories based on a better understanding of the workings of the human mind. Hence, as a result of an enormous joint effort, a comprehensible description of the cause of the origin of mankind is emerging. This allows “love”, once considered as merely a simple emotion, to be at the very core of explaining the evolutionary characteristics of the human being.

Language Genesis  [PDF]
Enrique Burunat
Advances in Anthropology (AA) , 2015, DOI: 10.4236/aa.2015.52008
Abstract: Language is a specifically human mental function, although some neurobiological adaptations associated with communication can be found in other primates, in other mammalian orders, and even in other kinds of animals (evolutionary trend). Exposure to language is necessary for its acquisition (culture), there are specific alleles of some genes for human language (gene), and the brain circuits for language are mainly lateralized towards the left hemisphere (brain lateralization). However, some data suggest that the crucial factor for human verbal language, which originates in childhood in both, ontogeny and phylogeny, must be of motivational nature, and have at least the same importance as other genetic, brain or cultural factors. So, this article proposes that language was promoted by the building of love, and that it was maintained by hominid women as proto-language during some hundreds of thousands years through the maternal-filial interaction, until the first permanent settlements of the current human species, between 40,000-10,000 years ago. Also, that it was then when the woman transmitted speech to the man (it is further suggested that this may have been the Original Sin of the biblical Genesis), signalizing this transmission with the beginning of the symbolic thought, thus promoting the first artistic displays, like sculptures, painting or music, which were associated with the expansion of love and speech to the relationship between the sexes, with the consequent diversification of languages, mainly in the last 10,000 to 5,000 years. Love caused and causes human speech in both, phylogeny and ontogeny.
Love Is Not an Emotion  [PDF]
Enrique Burunat
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.714173
Abstract: Romantic love—referred to as love—, is a physiological drive, but society has come to understand it as an emotion. Nevertheless, many researchers, mainly psychologists, have established its impulsive and motivational characteristics, which are even similar to those of addictive drug abuse. However, many professionals in the field of psychology and psychiatry still consider love to be a complex emotion or feeling. This article describes some of the causes and consequences of the extensive confusion between love and emotion. Some reasons to consider love as a physiological motivation, like hunger, thirst, sleep and sexuality are also summarized. A Love Withdrawal Syndrome is proposed. It concludes by highlighting the urgency to eliminate love from the catalogue of emotions in psychology, as an item or cluster in psychological tests, and also as an emotional mental function, by contributing to its dramatic consequences, mainly divorces, suicides and femicides.
Trk Family Neurotrophin Receptors and p75 Receptor. A Multiple Competing Hypothesis Case in the Nerve Growth Factor (NGF) History  [PDF]
Enrique Wulff Barreiro
Advances in Historical Studies (AHS) , 2014, DOI: 10.4236/ahs.2014.32009
Abstract: In the area of Trk oncogene, this research has revealed the different competing hypotheses made at the time of its discovery. A conflict of interest arose within the group who identified it as the nerve growth factor receptor (NGF). An auxiliary assumption, on the cardinal importance of the low affinity p75 receptor, resulted in that the consistency of the group take patterns of competence. The level of provocation affected the joint effort. An environment reminds the denial that Stehelin was given by Varmus and Bishop, in the race for the Nobel Prize in Physiology or Medicine. Nowadays p75 receptor functions are described as “enigmatic”, and accepted that all the neurotrophins interact with two types of receptors: the specific to the ligands of the high-affinity Trk family of receptors and the low affinity p75 receptor (with structural similarities to the tumor necrosis factor and in liaison with the development of eye optical fiber). Against this background, papers concerning this subject and included in the ISI citation database are analysed, categorizing them through a system of descriptors, according to their original publication date. Complete time vectors are approximated by setting the analysis with a growth model based on Gompertz function. After the criteria used by authorities like Rita Levi-Montalcini, Luigi Cavalli-Sforza, Rodolfo Llinás and Victor McKunsick the selected material resulted in a database with 371 records. The data suggest the opportunity for historical sciences of a non-discrimination compliance test performed on multiple hypotheses.
The Fate of Ochoa’s School in the Origins of Oncogenetics in US (I)  [PDF]
Enrique Wulff-Barreiro
Open Journal of Genetics (OJGen) , 2014, DOI: 10.4236/ojgen.2014.45037
Abstract: It was in the early eighties that a genuine school of spanish biochemists around Severo Ochoa participated in the oncogene races. Malignant cell transformation and oncogenes were put in relation during that era. Several prominent scientists coming from Spain have established and maintained a strong tradition of studies in the enzymology of retroviruses and transcriptional events. In this short historical account, we briefly pay tribute to these famous forerunners, by emphasizing both the originality and quality of their work, as well as the many accompanying conceptual and methodological analysis. We start with àngel Pellicer (1948-) who, amongst other contributions, first established the landmark experimental transfection protocol and nucleated the onset of oncogenetics with his discovery that ras oncogenes were activated by mitogenic factors. Whereas Manuel Perucho (1948-) can be considered as one of the pioneers, if not the founder, of the cloning of human oncogene, through his experiments on H-ras, and he became a milestone in diagnostic detection to allow hospital technicians to screen for mutant ras genes. More known Mariano Barbacid (1949-) established that ras oncogene was a kind of common denominator for cancer, and clarified that their functional differences were by a single point mutation. In conclusion, this history demonstrates how eager spanish biochemists trained by Eladio Viñuela were to maintain the tradition of Severo Ochoa’s long-standing scientific reputation in the US.
