introduction: ischemia leads to loss of neurons by apoptosis in specific brain regions, especially in the hippocampus. the purpose of this study was investigating the effects of exercise preconditioning on expression of bax, bcl-2, and caspase-3 proteins in hippocampal ca1 neurons after induction of cerebral ischemia. methods: male rats weighing 260-300 g were randomly allocated into three grou...

Calcium aluminosilicate hydrate (C-A-S-H) is the binding phase of both blended cement-based and alkali-activated materials. The intrinsic mechanical properties non-cross-linked C-A-S-H are important while experimentally unvalidated. Here, for first time measured using high-pressure X-ray diffraction. incompressibility bulk modulus K0 C-A-S-Hs correlated to their nanostructure stability nuclear ...

The character table of the fully nonrigid water cluster (cyclic forms), (H_{2}O){_i}, with C{_ih} symmetry derived for the first time, for 2<=i <=6. The group of all feasible permutations is the wreath product of groups S{_i}[S{_2}] which consists of i!2i operations for i = 2, ..., 6 divided into ( w.r.t) 5, 10, 20, 36, 65 conjugacy classes and 5, 10, 20, 36, 65 irreducible representations resp...

conclusions our outcomes showed elevated incidences of tsst-1 positive and mrsa strains with higher rates of antibiotic resistance. the conflict between our findings and other records may be due to differences in geographic regions. materials and methods the presence of the tsst-1 and meca genes was investigated by polymerase chain reaction (pcr) among s. aureus isolated from 197 clinical sampl...

The hit compound 1,2,4-triazolo[4’,3’:2,3]pyridazino[4,5-b]indole 3 was synthesized from the reflux of 4-amino-5-indolyl-1,2,4-triazole-3-thione 1 with 4′-bromoacetophenone 2 in methanol catalyzed by concentrated HCl and desired final molecule obtained recrystallization methanol. suggested structures compounds based on spectral characterizations were confirmed X-ray single crystal diffraction a...

This study is undertaken to explore the relationship between reaction products and drying shrinkage of alkali-activated slag (AAS) with varying hydroxide dosage. AAS pastes were firstly produced either Al(OH)3 or Mg(OH)2 investigate effects on composition AAS. Secondly, main formed in pastes, viz. C4AH13, M4AH10, C-S-H, C-A-S-H C-M-S-H, synthesized individually. Synthetic then taken cast respec...

in this work, an optical sensor for detection of ascorbic acid is described. the sensor is fabricated by casting and spin-coating silica sol-gel doped with 2,6-dichlorophenol indophenol on the glass plates. the sols are in turn obtained by acidic hydrolysis of various precursors such as tetraethoxysilane, triethoxymethylsilane and triethoxyoctylsilane in the presence of 2,6-dichlorophenol indop...

background: given that validity is the baseline of psychological assessments, there is a need to provide evidence-based data for construct validity of such scales to advance the clinicians for evaluating psychiatric morbidity in psychiatric and psychosomatic setting. methods: this comparative cross-sectional study aimed to investigate the construct validity of the malaysian version of the ghq-2...
