The incorporation of neutral hydrophilic monomer units in the hydrophobic B blocks BAB copolymers produces transient networks exhibiting a thermoresponsive behavior with maximum viscosity water.

The stratigraphic framework of the uppermost Jurassic Lower Cretaceous interval of the Gulf area is revised using both historical and recently acquired paleontological (ammonites, calpionellids, foraminifers, 'calcareous' algae), sedimentological and sequential information. The Kahmah regional Series ranging in age from Late Tithonian to Gargasian (= middle Aptian) times is subdivided into regi...

The development of morphological traits occurs through the collective action of networks of genes connected at the level of gene expression. As any node in a network may be a target of evolutionary change, the recurrent targeting of the same node would indicate that the path of evolution is biased for the relevant trait and network. Although examples of parallel evolution have implicated recurr...

The aim of this double-blind randomised prospective study was to assess the effect of subconjunctival Betnesol (betamethasone sodium phosphate 0.1%) on the recovery of the blood aqueous barrier (BAB) following cataract surgery in uncomplicated eyes. Twenty patients [10 male, mean age 71.4 (SD 12.7) years] admitted for routine cataract surgery were randomised into two groups. All patients recrui...

The permeability of the blood-ocular barrier was examined by fluorophotometry in adolescent and adult diabetic patients before the onset of retinopathy. The adolescent group consisted of 52 eyes of 52 insulin dependent diabetic patients aged 11 to 19 years and a control group of 10 eyes of 10 normal adolescents. The adult group consisted of 74 eyes of 74 non-insulin dependent diabetics and a co...

AIMS To evaluate whether long-term treatment with the prostaglandin analogue latanoprost has a deleterious effect on the blood-aqueous barrier (BAB) and to determine the duration of the effect on intraocular pressure (IOP) after withdrawal of treatment. METHODS Patients with ocular hypertension or glaucoma were topically treated with latanoprost 50 micrograms/ml once daily for 6-12 months. In...

Helicobacter pylori (H. pylori) infection has been reported in more than half of the world human population. It is associated with gastric inflammation and noticeable infiltration of the immune cells to the stomach mucosa by several cytokines secretion. IL-1β, IL-18 have been shown to contribute to H. pylori induced gastritis, but the details of inflammation and association of virulence factors...

This article presents a study on the tertiarization phenomenon of Algerian cities built after independence, to provide adequate housing and access better living conditions. To be more effective in our research, we selected as case municipality Bab Ezzouar. Ezzouar is city during seventies receive eastern extension capital Algiers through mass habitat-production project – but had been for long t...
