The Widom–Rowlinson model (or the Area-interaction model) is a Gibbs point process in Rd with formal Hamiltonian defined as volume of ∪x∈ωB1(x), where ω locally finite configuration points and B1(x) denotes unit closed ball centred at x. also tuned by two other parameters: activity z>0 related to intensity inverse temperature β≥0 strength interaction. In present paper we investigate phase trans...

Two new spirostane glycosides, named polygokingiaside A (1) and B (2), 6 known (25 R)-26- O-( β-d-glucopyranosyl)-furost-5-en-3 β,22 α,26-triol 3- O-β-d-glucopyranosyl-(1→4)- β-d-galactopyranoside (3), S)-26- O-β-d-glucopyranosyl-(1→2)- β-d-glucopyranosyl-(1→4)- (4), (5), (23 S,25 R)-spirostan-5-en-3 β,23-dihydroxy-12-one-3- (6), (24 β,24-dihydroxy-12-one-3- (7), β-hydroxy-12-one-3- (8), were i...

In the present paper, we report crystal structures of four types ([A(1)H][A(2)H]Y, [A(1)H]3[A(2)H]Y2, A(1)H[A(2)H···A(2)]Y, and A(1)H[A(1)H···A(2)]Y) mixed salts containing sulfate anion (Y = SO42−) amino acids A, i.e., sarcosine (Sar), dimethylglycine (DMG), betaine (Bet), β-alanine (β-Ala), l-proline (l-Pro): (β-AlaH)(DMGH)SO4·2H2O (I), (β-AlaH)(BetH)SO4 (II), (β-AlaH)(l-ProH)SO4 (III), (BetH...

background: extended spectrum β-lactamases (esbls) and ampc β-lactamases enzyme are major sources of resistance to β-lactam antibiotics especially in enterobacteriaceae such as escherichia coli and klebsiella pneumoniae. increasing frequency of the co-existence of esbls with ampc-β-lactamases in bacteria is a serious threat for treating bacterial infections. conclusions: outbreak of isolates co...

During recent years, there was growing demand in using microalga valuable products such as β-carotene in health care. β-Carotene has anti-cancer and anti-aging properties for human. In Dunaliella salina cells, β-carotene has a major protecting role for biomolecules, when the production of reactive oxygen species elevated. In the present study, we investigated the influence of the four most effe...

Sonochemical procedure was used to synthesize Co/β-cyclodextrin complex. For the first time, Fe/β-cyclodextrin complex also synthesized in alkaline media. Moreover, β-cyclodextrin modified by citric acid (CA) and reacted with metal salts under ultrasonic irradiation. The prepared catalysts were characterized using EDX, UV–vis FTIR analytical techniques. highest incorporation of into observed cr...

cow’s milk allergy is one of the most common food allergies in childhood. beta- lactoglobulin (β-  lg) is  a dominant  allergen in  cow’s milk. hydrolysis is  known as  an effective method to reduce the allergenicity of proteins. thus, the objective of this study was to compare the allergenicity of β-lg and its hydrolysates using an animal model. twenty four balb/c mice were divided into three ...

We consider a G-function F(z)=∑k=0∞Akzk∈K〚z〛, where K is number field, of radius convergence R and annihilated by the G-operator L∈K(z)[d/dz], parameter β∈Q∖Z⩽0. define family G-functions Fβ,n[s](z)=∑k=0∞Ak(k+β+n)szk+n indexed integers s n. Fix α∈K⁎∩D(0,R). Let Φα,β,S be K-vector space generated values Fβ,n[s](α), n∈N, 0⩽s⩽S. show that there exist some positive constants uK,F,β vF,β such uK,F,β...

Background: Approximately 180 mutations have been described in β-thalassemia worldwide with specific spectrum in each ethnic population. This study determines the spectrum and the frequency of β-thalassemia mutations in patients with β-thalassemia trait and sickle cell-β-thalassemia. Methods: Fifteen compound heterozygous sickle cell thalassemia (SCT) and 23 β-thalassemia trait patients were st...
