Vanadium is a trace element mainly connected with regulation of insulin metabolism which is particularly important in diabetes. In recent years, organic complexes of vanadium seem to be more interesting than inorganic salts. Nevertheless, the effect of vanadium on lipid metabolism is still a problematic issue; therefore, the main purpose of this study was to investigate the effect of 3 organic complexes of vanadium such as sodium (2,2'-bipyridine)oxidobisperoxovanadate(V) octahydrate, bis(2,2'-bipyridine)oxidovanadium(IV) sulfate dehydrate, and bis(4,4'-dimethyl-2,2'-bipyridine)oxidovanadium(IV) sulfate dihydrate in conjunction with high-fat as well as control diet in nondiabetes model on the following lipid parameters: total cholesterol, triglycerides, and high density lipoprotein as well as activity of paraoxonase 1...

Photosynthesis and lipid allocation were investigated in Rubisco small subunit mutants of the microalga Chlamydomonas reinhardtii. Comparative analyses were undertaken with cells grown photoheterotrophically under sulphur-replete or sulphur-depleted conditions. The Y67A Rubisco mutant, which has previously demonstrated a pronounced reduction in Rubisco levels and higher hydrogen production rates than the wild type, also shows the following divergences in photosynthetic phenotype and lipid allocation: (i) low Fv/Fm (maximum photochemical efficiency), (ii) low effective quantum yield of photosystem II (ΦPSII), (iii) low effectiveness at protection against high light intensities, (iv) a higher level of total lipids per pigment and (v) changes in the relative proportions of different fatty acids, with a marked decrease in unsaturated fatty acids (FAs)...

Isovaleryl coenzyme A (IV-CoA) is an important precursor for iso-fatty acids and lipids. It acts in the development of myxobacteria, which can produce this compound from acetyl-CoA through alternative IV-CoA biosynthesis (aib). A central reaction of aib is catalyzed by AibA/AibB, which acts as a cofactor-free decarboxylase despite belonging to the family of CoA-transferases. We developed an efficient expression system for AibA/AibB that allowed the determination of high-resolution crystal structures in complex with different ligands...

Solid lipid nanoparticles (SLNs) are among the most promising nanocarriers to target the blood-brain barrier (BBB) for drug delivery to the central nervous system (CNS). Encapsulation of the acetylcholinesterase reactivator, pralidoxime chloride (2-PAM), in SLNs appears to be a suitable strategy for protection against poisoning by organophosphorus agents (OPs) and postexposure treatment. 2-PAM-loaded SLNs were developed for brain targeting and delivery via intravenous (iv) administration. 2-PAM-SLNs displayed a high 2-PAM encapsulation efficiency (∼90%) and loading capacity (maximum 30...

Serous ovarian cancer (SOC) is usually diagnosed at late stage and stage-adjusted five year survival rate is low. Mortality is relatively heavy on African-Americans/Black (AA) affected with SOC compared to their Caucasian counterparts, though the cause for the disparity remains unclear. DNA damage induced by oxidative stress has been linked to ovarian cancer, but the role of oxidative stress in distinguishing differences in aggressive SOC tumors among patients is yet to be determined. This study aims to determine the levels of reactive oxygen species (ROS), malondialdehyde (MDA), reactive carbonyl groups and antioxidants in primary SOC normal, precancerous (cystadenoma, borderline) and invasive (III/IV) tissue samples obtained from AA and Caucasian subgroups...

Trans-chalcone (TC) is a common precursor of flavonoids. However, the pharmacological properties of TC remain to be fully understood. The present study investigated whether topical formulation containing TC (TFcTC) presents therapeutic effect in UVB radiation-induced skin damage using disease, enzyme activity, antioxidant activity, protein and mRNA parameters. Control topical formulation (CTF) and TFcTC were applied in hairless mice before and after exposure to UVB radiation. Dorsal skin samples were collected after UVB exposure to evaluate: i) skin edema (weight) was measured by punch biopsy; ii) spectrophotometric assays were used to measure myeloperoxidase (MPO) and catalase activities, ferric (FRAP) and ABTS cation reducing antioxidant power, superoxide anion production and levels of reduced glutathione (GSH); iii) enzymography was used to measure matrix metalloproteinase-9 (MMP-9) activity; iv) chemiluminescence was used to measure the lipid peroxidation (LPO); v) enzyme-linked immunosorbent assay (ELISA) was used to measure tumor necrosis factor alpha (TNF-α) levels; vi) reverse transcription quantitative PCR (RT-qPCR) was used to measure cyclooxygenase-2 (COX-2), gp91(phox) (NADPH oxidase sub-unity), glutathione peroxidase-1 (Gpx1), glutathione reductase (Gr), nuclear factor erythroid 2-related factor 2 (Nrf2), and heme oxygenase-1 (HO-1) mRNA expression...

RhoA is widely expressed throughout the female reproductive system. To assess its role in progesterone receptor (Pgr) expressing cells, we generated RhoA conditional knockout mice RhoAd/d (RhoAf/f-Pgr-Cre+/-). RhoAd/d females had comparable mating activity, serum LH, prolactin, and estradiol levels and ovulation with control but were infertile with progesterone insufficiency, indicating impaired steroidogenesis in RhoAd/d corpus luteum (CL). RhoA was highly expressed in wild type luteal cells and conditionally deleted in RhoAd/d CL...

Spindle cell lipoma (SCL) is a benign neoplasm of the adipose tissue that may resemble an undifferentiated soft tissue sarcoma (STS). This report describes the histopathological features of 6 SCLs in dogs. All SCLs were located in the subcutis and were composed of bland, occasionally vacuolated spindle cells intermixed with ropey collagen and myxoid matrix. Sudan IV stain performed in 1 case demonstrated the lipid content of vacuoles. Mature adipocytes represented less than 10% of the neoplasm in 3 cases and were absent in the remaining 3...

Microenvironment plays an important role for stem cell proliferation and differentiation. Macromolecular crowding (MMC) was recently shown to assist stem cells in forming their own matrix microenvironment in vitro. The ability of MMC to support adipose stem cell (ASC) proliferation, metabolism, and multilineage differentiation was studied under different conditions: fetal bovine serum- (FBS-) and human serum- (HS-) based media and xeno- and serum-free (XF/SF) media. Furthermore, the immunophenotype of ASCs under MMC was evaluated...
