#1
Thierry Nicolas Jean Fouquet, Takaya Satoh, Hiroaki Sato
Its recent adaptation to low-resolution mass spectra of polymers using fractional base units raises the question of the minimal resolution needed for a Kendrick mass defect (KMD) analysis. Intuiting an oligomeric resolution since the mass of a repeat unit is the sole value to be known, it is challenged by the relative failure of the KMD plots computed from an isotopically resolved MALDI-TOF mass spectrum to display clear alignments in the high mass range. Another procedure based on the remainders of Kendrick mass (RKMs) overcomes this pitfall with oligomers perfectly aligned in a new RKM plot...

REVIEW
Renger F Witkamp
Intake, absorption and synthesis of fatty acids, including those produced by the intestinal microbiota are tightly monitored via specific receptors and, indirectly through their conversion into a variety of signalling molecules. The resulting information is integrated and translated to different physiological processes, including the regulation of appetite and satiation. Direct chemosensing of fatty acids takes place via interaction with free fatty acid (FFA) and other receptors. These are present in the oronasal cavity and along the entire gastrointestinal tract, in various other tissues, and, for some receptors also in brain...

Kazuhiro Nakamura
Thermoregulatory behavior in homeothermic animals is an instinctive behavior to reduce the cost of their homeothermy, such as warm-seeking behavior to reduce metabolic energy for heat production in cold environments. A recent study identified the central neural pathway that transmits cutaneous thermosensory information on environmental temperature to drive thermoregulatory behavior. This study proposed that the brain mechanism that drives thermoregulatory behavior does not require conscious"feeling"(i.e., perception)of skin temperature mediated by the spinothalamocortical pathway, whereas thermosensory information that ascends through the spinal cord and the lateral parabrachial nucleus of the pons generates thermal comfort and discomfort that drive thermoregulatory behavior...

To explore the bridge role of Jingming (BL 1) for video display terminal (VDT) asthenopia and brainfag. Ancient literature and modern scientific research on the acupoint have been analyzed and summarized so as to explore pressing the acupoint the instinct feedback of brain after asthenopia. It is demonstrated that Jingming (BL 1) is a key channel between eyes, brain and the outside world, and it is one of major feedback points of brain after asthenopia. In this paper we try to establish a new research thinking and ascertain it, namely Jingming (BL 1) reflecting the relationship between asthenopia and brainfag...

Evidence supporting the practice of skin-to-skin contact and breastfeeding soon after birth points to physiologic, social, and psychological benefits for both mother and baby. The 2009 revision of Step 4 of the WHO/UNICEF "Ten Steps to Successful Breastfeeding" elaborated on the practice of skin-to-skin contact between the mother and her newly born baby indicating that the practice should be "immediate" and "without separation" unless documented medically justifiable reasons for delayed contact or interruption exist...

After World War II came to an end, General Franco's regime attempted to step aside from the defeated fascist states by emphasizing its Catholic character. The change of image culminated in 1947 with the establishment of Spain as a Catholic State by means of the Law of Succession. This process generated the national catholic ideology, which became, during the first decades of the dictatorship, the hegemonic instrument for the transformation of Spanish society in an anti-modernizing way. Scientific activity was not excluded from these changes, and a Catholic science conveying universal values and in harmony with the faith was strongly encouraged...

REVIEW
Fayez K Ghishan, Pawel R Kiela
Indiscriminate use of multivitamin/mineral supplements in the general population may be misguided, but patients with chronic Inflammatory Bowel Diseases (IBD) should be monitored and compensated for nutritional deficiencies. Mechanistic links between vitamin/mineral deficiencies and IBD pathology has been found for some micronutrients and normalizing their levels is clinically beneficial. Others, like vitamin A, although instinctively desirable, produced disappointing results. Restoring normal levels of the selected micronutrients requires elevated doses to compensate for defects in absorptive or signaling mechanisms...

Aim: This paper sheds light on the context that leads some querulous patients to self-immolate in front of, or into, public buildings (e.g., tribunals, city halls, and employment agencies). Method: The author defines paranoid querulousness. A psychoanalytic perspective, but also a judicial and a psychiatric point of view, over querulous claimants is presented. The links between political or social claims and self-immolation are studied. The expression of suicidal thoughts voiced by four querulous subjects is analyzed...

Après-coup, Freud's Nachträglichkeit, is an essential psychoanalytic concept structuring each of four concepts, four mental processes that lie at the foundation of Freud's thinking: psychic trauma, repression, the creation of the unconscious, and the creation of infantile sexuality. It is argued here that infantile sexual drives, in contrast to the self-preservative instincts, arise from a two-step process of translation and repression in which the residues of failed translation become source-objects of the drives...

Catatonia is a clinical syndrome characterized by symptoms such as immobility, mutism, stupor, stereotypy, echophenomena, catalepsy, automatic obedience, posturing, negativism, gegenhalten and ambitendency. This syndrome occurs mostly in mood disorder and schizophrenic patients, and is related to neuronal dysfunction involving the frontal lobe. Some cases of frontotemporal dementia (FTD) with catatonia have been reported, but these cases were not examined by autopsy. Here, we report on a FTD case which showed catatonia after the first episode of brief psychotic disorder...

Mankind has been expressing the breeding topic for thousands of years. Reproduction is the primary instinct of human beings and it is a social, cultural, medical issue. Demographic infertility is one of them, which is defined infertility as the inability to become pregnant with a live birth, within five years of regular sexual contact based upon a consistent union status in marriage maintaining a desire for a child with the lack of contraceptive use and non-lactating. A first mentions about infertility and surrogacy is discovered on a 4000-year-old clay tablet of marriage contract belonging to the Assyrian period exhibited at Istanbul Archeology Museum in Turkey...

Piotr Podlipniak
From the biological perspective human musicality is the term referred to as a set of abilities which enable the recognition and production of music. Since music is a complex phenomenon which consists of features that represent different stages of the evolution of human auditory abilities, the question concerning the evolutionary origin of music must focus mainly on music specific properties and their possible biological function or functions. What usually differentiates music from other forms of human sound expressions is a syntactically organized structure based on pitch classes and rhythmic units measured in reference to musical pulse...

All animals possess a repertoire of innate (or instinctive) behaviours, which can be performed without training. Whether such behaviours are mediated by anatomically distinct and/or genetically specified neural pathways remains unknown. Here we report that neural representations within the mouse hypothalamus, that underlie innate social behaviours, are shaped by social experience. Oestrogen receptor 1-expressing (Esr1+) neurons in the ventrolateral subdivision of the ventromedial hypothalamus (VMHvl) control mating and fighting in rodents...

BACKGROUND: Planarians, like rodents, instinctively spend more time in dark versus light environments when given a choice. This behavioral phenomenon is called negative phototaxis, which may reflect defensive responding related to an anxiety-like phenotype. NEW METHOD: We propose a planarian light/dark test, designated PLDT, to predict anxiogenic- or anxiolytic-like effects. Experimentally, we placed a planarian at the midline of a Petri dish, containing test compound or water, that was split evenly into light and dark compartments and determined time spent in the light over 10min...
