We present a new English translation of L.E.J. Brouwer’s paper ‘De onbetrouwbaarheid der logische principes’ (The unreliability of the logical principles) of 1908, together with a philosophical and historical introduction. In this paper Brouwer for the first time objected to the idea that the Principle of the Excluded Middle is valid. We discuss the circumstances under which the manuscript was ...

introduction : constipation is one of the most prevalent causes of abdominal pain in pediatrics, with no underlying pathology. it is defined as functional constipation in 95% of cases evaluated. this study was designed to compare the therapeutic effect of polyethylene glycol (peg) and lactulose in treating chronic functional constipation in children. materials and methods: in this randomized, d...

The ground state properties of CeCoPO, a homologue of the new high temperature superconductors LnFePnO1−xFx, were studied by means of susceptibility, specific heat, and resistivity measurements on polycrystals. The observation of a well defined Curie-Weiss behavior above 230K with μeff = 2.9μB and a ferromagnetic ordering below TC = 75K is similar to what was observed in LaCoPO and points to ma...

Background and Objectives: According to recent research, olive leaf (OL) has demonstrated significant properties, including antibacterial, antiviral, anticancer, gastro protective and cardio protective properties. The aim of this study was to investigate the chemical composition, and fatty acid composition (FAC) of OL of Marry variety cultivated in Jiroft province of Iran. This study also attem...

The peripheral subunit-binding domain (PSBD) of the dihydrolipoyl acetyltransferase (E2, EC 2.3.1.12) binds tightly but mutually exclusively to dihydrolipoyl dehydrogenase (E3, EC 1.8.1.4) and pyruvate decarboxylase (E1, EC 1.2.4.1) in the pyruvate dehydrogenase multienzyme complex of Bacillus stearothermophilus. Isothermal titration calorimetry (ITC) experiments demonstrated that the enthalpie...

This experiment was conducted to investigate the effects of olive leaf (OL) on the performance, abdominal fat pad and some ileal bacterial population of Cobb broiler chickens. A total number of 400 day-old chicks were randomly distributed into floor pens and reared under the same condition until 14 days of age. On day 14, each pen was randomly assigned to one of the five experimental treatments...

bostan ol-arefin va tohfat ol-moridin is one of the mystical prose texts of the khorasan area in the fifth century a.h. among the many persian literary texts, it is considered as a precious ancient source for many of the anecdotes, miracles and sayings of the sufis. furthermore, the linguistic features of this book such as numerous special vocabularies, stylistic aspects and prose similar to th...

3,7-Dimethylpentadecan-2-ol and 3-methylpentadecan-2-ol were identified in female whole body extracts from the two pine sawfly species Gilpinia frutetorum and Gilpinia socia. This is the first observation of 3-methylpentadecan-2-ol in extracts of a female pine sawfly species. Synthetic and highly pure stereoisomers of 3,7-dimethylpentadecan-2-ol and 3-methylpentadecan-2-ol were used to verify t...

Oligodendrocytes (OLs), the myelin-forming CNS glia, are highly vulnerable to cellular stresses, and a severe myelin loss underlies numerous CNS disorders. Expedited OL regeneration may prevent further axonal damage and facilitate functional CNS repair. Although adult OL progenitors (OPCs) are the primary players for OL regeneration, targetable OPC-specific intracellular signaling mechanisms fo...
