Hypothesis: The adsorption isotherm of alkanols at the haematite|hydrocarbon interface should reflect both chemisorption (chemically bonded fraction) and physisorption (hydrogen bonded fraction).
Experiments And Model: Quartz crystal microbalance (QCM) and X-ray photoelectron spectroscopy (XPS) have been used for characterization of FeO|hydrocarbon interfaces with absorbed alcohol. A range of FeO-terminated surfaces, alkanols, hydrocarbons and temperatures have been investigated.
We report the reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization of 2-hydroxyethyl methacrylate (HEMA) in -dodecane using a poly(lauryl methacrylate) (PLMA) precursor at 90 °C. This formulation is an example of polymerization-induced self-assembly (PISA), which leads to the formation of a colloidal dispersion of spherical PLMA-PHEMA nanoparticles at 10-20% w/w solids. PISA syntheses involving polar monomers in non-polar media have been previously reported but this particular system offers some unexpected and interesting challenges in terms of both synthesis and characterization.

Our study thus aimed to molecularly characterize colorectal cancer liver metastases (CRCLMs) and explore whether molecular profiles differ between Synchronous (SmCRC) and Metachronous (MmCRC) colorectal cancer. This characterization was performed by whole exome sequencing, whole transcriptome, whole methylome, and miRNAome.

Patients And Methods: Materials and methods: The study involved 294 patients who were receiving inpatient treatment at Communal Non-Profit Enterprise «Uzhgorod Central City Clinical Hospital»,Communal Non-Profit Enterprise «Transcarpathian Regional Clinical Hospital» and Communal Non-Profit Enterprise «Uzhgorod District Clinical Hospital». The study was conducted in 36 patients of pulmonological, 52 - neurological, 22 - endocrinological, 28 - rheumatological, 67 - general therapeutic and 89 - surgical patients.
Five new complexes with metal cations (Mn, Fe, Co, Ni, and Cu) of monolacunary Keggin monovanado-deca-tungstophosphate, K[PVWO]·15HO, have been synthesised. The molar ratio of the combination between metal cations and K[PVWO]·15HO has been established to be 1:1, and its general molecular formulas were found to be: K[MPVWO(HO)]·xHO ( = 5 for M = Fe and = 6 for M = Mn, Co, Ni, and Cu). Optimal conditions for complexes' synthesis (pH, temperature, and reaction time) have been determined.

The treatment of middle ear cholesteatoma requires surgical treatment and the reconstruction of the temporal bone, which represents an ongoing problem. Otologists have focused on the research of materials allowing an airy middle ear and the preservation of hearing function to reconstruct the temporal bone. This study evaluated the effect of cyclosporin A (CsA) and a combined biomaterial in the healing process of postoperative temporal bone defects in an animal model.

In this review, we have shown that through coacervation, the particulate systems for the dispensing of drugs consisting of natural polymers are nontoxic, allowing the repeated administration of medicinal substances and the protection of better the medicinal substances from degradation, which can increase the capture capacity of the drug and extend its release from the pharmaceutical form.

Colorectal cancer (CRC) has been recognized as one of the most common causes of STOs in Western countries. Despite it being well-known that CRC originating from the right versus left side of the colon/rectum differ substantially, there is a paucity of information regarding the effect of the primary tumor sidedness on the clinicopathological characteristics of STOs.
