Altered production of β-amyloid (Aβ) from the amyloid precursor protein (APP) is closely associated with Alzheimer's disease (AD). APP has a number of homo- and hetero-dimerizing domains, and studies have suggested that dimerization of β-secretase derived APP carboxyl terminal fragment (CTFβ, C99) impairs processive cleavage by γ-secretase increasing production of long Aβs (e.g., Aβ1-42, 43). O...

Abstract Coral reefs are restricted to warm waters, but increasingly threatened by coral bleaching induced sustained high sea surface temperatures. endosymbiont thermal resilience has been proposed depend, at least in part, on the lipid composition of their thylakoid membranes, which influences photosynthetic performance under sub- and super-optimal conditions organisms. Dinoflagellate symbiont...

Quantum chemical calculations combined with statistical thermodynamic computations expose the electronic structure and high thermodynamic stability of Dy(2)@C(100), a D(5)-symmetric endohedral metallofullerene.

Ab initio total energy calculations reported recently (M.I. Heggie, C.D. Latham, R. Jones and P.R. Briddon, Phys. Rev. B, 50 (1994) 5937) revealed that the tetrahedrally bonded icosahedral C100 molecule spontaneously decomposed into two concentric fullerenes (C20 and C80). This C100 molecule belongs to a series of structures that may be viewed as the diamond analogues of fullerenes (L. Zeger an...

Mycolic acid-producing bacteria isolated from the respiratory tract of human and non-human mammals were recently assigned as a distinct genus, Segniliparus, because they diverge from rhodococci and mycobacteria in genetic and chemical features. Using high accuracy mass spectrometry, we determined the chemical composition of 65 homologous mycolic acids in two Segniliparus species and separately ...

Aim: To evaluate the cardiovascular effect of carvacrol treatment in a D(+)galactose accelerated aging model, investigating effects on vascular reactivity, oxidative stress, and systolic blood pressure (SBP).
 Methodology: Eight-week-old male Wistar rats (Rattus norvegicus) were used for oral eight weeks. Organ baths reactivity studies (FEN, ACh, NPS), fluorescence microscopy to detect rea...

Drought stress is a serious adverse factor limiting growth and productivity of sunflower. Evaluation of defense systems is important for producing resistant cultivars. In this study, some agro-morphological and molecular characteristics of six sunflower lines were evaluated under normal and irrigation at 40 and 60% of field capacity in randomized complete block design (RCBD). The results showed...

The influence of mixing alfalfa with whole-plant corn in different proportions on the fermentation characteristics and bacterial community silage was investigated. Alfalfa corn, harvested at dry matter content 276.47 328.43 g/kg fresh weight, accordingly, were chopped to approximately 2 cm mixed ratios 100:0 (C0, control), 80:20 (C20), 60:40 (C40), 40:60 (C60), 20:80 (C80) 0:100 (C100) a weight...
