Let Md be the centered Hardy-Littlewood maximal function associated to cubes in R with Lebesgue measure, and let cd denote the lowest constant appearing in the weak type (1,1) inequality satisfied by Md. We show that cd → ∞ as d → ∞, thus answering, for the case of cubes, a long standing open question of E. M. Stein and J. O. Strömberg.

The association between pediatric celiac disease (CD) and atherosclerosis is unknown. Our aim was to investigate whether pediatric CD patients have an increased risk of atherosclerosis. We evaluated the premature atherosclerosis by pulse wave velocity (PWV) and carotid intima-media thickness (cIMT). A total of 37 CD patients (20 girls, mean age 13±3.3 years) and 36 healthy age and sex matched c...

Herein we present the synthesis and the photophysical evaluation of water-soluble chiral ligands (2·(R,R) and 2·(S,S)) and their application in the formation of lanthanide directed self-assembled structures. These pyridine-2,6-dicarboxylic amide based ligands, possessing two naphthalene moieties as sensitising antennae, that can be used to populate the excited state of lanthanide ions, were str...

We repor t the modula t ion of the solu t ion rheology of a comblike, hydrobhobica lly modified a lka li-soluble emulsion (HASE) associa t ive polymer through addit ion of Rand !-cyclodext r ins (CDs). The r ing-shaped CDs with hydrophobic inner cores in teract with the pendant macromonomer segments of the associa t ive polymer conta in ing hydrophobic end groups, leading to reduct ion in polym...

BACKGROUND Pediatric patients with chronic kidney disease (CKD) are at increased risk of early cardiovascular disease and premature death. Abnormalities in microvascular structure and function may presage end-organ damage including vascular calcification and myocardial ischemia associated with disordered mineral metabolism. Early detection of microvascular rarefaction (reduced density of capill...

Pot and field experiments were conducted to study the effects of mulching with straw of cadmium (Cd) tolerant plants (Ranunculus sieboldii, Mazus japonicus, Clinopodium confine and Plantago asiatica) on growth and Cd accumulation of Galinsoga parviflora in Cd-contaminated soil. In the pot experiment, mulching with M. japonicus straw increased the root biomass, stem biomass, leaf biomass, shoot ...

Патології, що пов’язані або супроводжуються болем і запаленням, є одними з найрозповсюдженіших. Сьогодні немає аналгетика та протизапального препарату, який би оптимально задовольняв вимоги клініки щодо ефективності та/чи безпеки. Тому пошук нових препаратів даної групи, переважають за своїми властивостями сучасні аналоги, важливий актуальний. Останніми роками в плані пошуку знеболюючих протиза...

lymphocyte cd4 + count, a standard laboratory test for staging of hiv infection, is expensive and unavailable in resource-restricted countries. total lymphocyte count (tlc) and hemoglobin (hb) are recommended as simple & inexpensive surrogates. the aim of this study was to assess the correlation, sensitivity and predictive power of these parameters as substitutes for cd 4 count. one hundred hiv...

The 24 hour urinary excretion of cadmium (U-Cd) and lead (U-Pb), and the excretion of beta-2- microglobulins and retinol binding protein concentration in spot urines, were determined in a random 4% sample of the population of a small Belgian town. Blood pressure and body weight were measured on two separate occasions. U-Cd averaged 2.4 nmol/24 h in 46 youths, increased with age, and was signifi...
