Beneficial Effects of Fructooligosaccharides Esterified with Lauric Acid in a Metabolic Syndrome Model Induced by a High-Fat and High-Carbohydrate Diet in Wistar Rats.

Metabolic syndrome (MS) is a group of abnormalities in which obesity, insulin resistance (IR), oxidative stress, and dyslipidemia stand out. This pathology predisposes to the development of cardiovascular diseases and diabetes. The ingestion of linear fructooligosaccharides (FOS) such as inulin reduces conditions such as hyperinsulinemia, increased body fat, and triglyceridemia.

Production and Characterization of Cross-Linked Aggregates of CCR11 Thermoalkaliphilic Recombinant Lipase.

Immobilization of enzymes has many advantages for their application in biotechnological processes. In particular, the cross-linked enzyme aggregates (CLEAs) allow the production of solid biocatalysts with a high enzymatic loading and the advantage of obtaining derivatives with high stability at low cost. The purpose of this study was to produce cross-linked enzymatic aggregates (CLEAs) of LipMatCCR11, a 43 kDa recombinant solvent-tolerant thermoalkaliphilic lipase from CCR11.

Expression of a Cutinase of with Polyester and PET-Plastic Residues Degradation Activity.

Cutinases are enzymes produced by phytopathogenic fungi like Moniliophthora roreri. The three genome-located cutinase genes of M. roreri were amplified from cDNA of fungi growing in different induction culture media for cutinase production.

Inhibition of Stearoyl-CoA Desaturase by Sterculic Oil Reduces Proliferation and Induces Apoptosis in Prostate Cancer Cell Lines.

Prostate cancer (PCa) is a common type of cancer affecting male population. PCa treatments have side effects and are temporarily effective, so new therapeutic options are being investigated. Due to the high demand of energy for cell proliferation, an increase in the expression and activity of lipogenic enzymes such as the stearoyl-CoA desaturase (SCD) have been observed in PCa.

Diversity of Bacterioplankton and Bacteriobenthos from the Veracruz Reef System, Southwestern Gulf of Mexico.

Bacterial diversity was explored among field samples and cultured isolates from coral reefs within the Veracruz Reef System. Bacterioplankton and bacteriobenthos were characterized by pyrosequencing 16S rRNA genes. Identified sequences belonged to the kingdom Bacteria and classified into 33 phyla.

Beneficial effects of an algal oil rich in ω-3 polyunsaturated fatty acids on locomotor function and D dopamine receptor in haloperidol-induced parkinsonism.

Introduction: Parkinson's disease (PD) is a chronic neurological disorder whose pathogenesis involves the loss of dopaminergic neurons and dopamine terminals, formation of Lewy bodies, and microgliosis. Its treatment includes dopamine-based drugs with limited results and adverse effects. Additionally, some neuroleptic drugs used for mental disorders produce side effects referred to as parkinsonism.

Comparative Survival and the Cold-Induced Gene Expression of Pathogenic and Nonpathogenic from Tropical Eastern Oysters during Cold Storage.

Expression of the regulatory stress gene controls the transcription of genes, which are involved in survival and adaptation to low temperatures. The purpose of this study was to assess the growth kinetics of naturally occurring . in shellstock oysters and in vitro and the cold-shock-induced expression of the and gene response in vitro during postharvest refrigeration.

Preventive Action of Sterculic Oil on Metabolic Syndrome Development on a Fructose-Induced Rat Model.

The metabolic syndrome (MS) underlies metabolic disorders considered risk factors for the development of diabetes and cardiovascular diseases, which are major causes of morbidity and mortality in most of the world. Sterculic acid has been proposed as a potential tool for the treatment of MS since it inhibits the activity of the stearoyl-CoA desaturase-1 (SCD1), a central enzyme in lipid metabolism. We analyzed the effect of sterculic oil (SO) co-administration with 30% fructose in drinking water on the development of MS in male Wistar rats.

Comparative Effect between Sardine Oil and Fish Oil Rich in Omega-3 Fatty Acids on Hypertension and the Membrane Composition of Adipocytes in SHR Rats.

Omega-3 polyunsaturated fatty acids, have an important role in reducing hypertriglyceridemia, these acids decrease the mortality for Coronary Heart Disease. Very important is the relationship between fatty acid biosynthesis and distribution in organs and tissues involved in insulin resistance and hypertension due to its role in the production of vasoactive eicosanoids and their effects on insulin sensitivity; which is estimated with the HOMA-IR index, which relates the physiological and metabolic behavior of glucose and insulin in the body. The aim of this project was to compare the effect of sardine oil and omega-3 oils rich in polyunsaturated fatty acids: EPA (≈30%) and DHA (≈50%) administered for 6 to 8 wk respectively; on the lipid composition of the plasma membrane of epididymal adipocytes in spontaneously hypertensive rats (SHR) and their relation to obesity, insulin resistance and hypertension.

Behavioral Effect of Sterculia apetala Seed Oil Consumption in Male Zucker Rats.

Sterculia apetala (order: Malvales, family: Sterculiaceae) seed oil contains two cyclopropene fatty acids: sterculic and malvalic acid. Both positive and negative effects have been associated with the consumption of sterculic oil. In Mexico, S.

Blue Maize Extract Improves Blood Pressure, Lipid Profiles, and Adipose Tissue in High-Sucrose Diet-Induced Metabolic Syndrome in Rats.

The effect of blue maize extract in factors related to metabolic syndrome (MS) in Wistar rats was investigated. Total polyphenols, monomeric anthocyanins, and antioxidant activity were analyzed in blue maize. MS was induced in Wistar rats fed with high-sucrose (HS) diet for 12 weeks.

A Canola Oil-Supplemented Diet Prevents Type I Diabetes-Caused Lipotoxicity and Renal Dysfunction in a Rat Model.

We investigated the effect of a canola oil-supplemented diet on the metabolic state and diabetic renal function of a type I diabetes experimental model. Male Sprague-Dawley rats were randomly divided into four groups: (1) normoglycemic+chow diet, (2) normoglycemic+a canola oil-supplemented chow diet, (3) diabetic+chow diet, and (4) diabetic+a canola oil-supplemented chow diet. For 15 weeks, animals were fed a diet of Purina rat chow alone or supplemented with 30% canola oil.

Gene Cloning and Characterization of the Geobacillus thermoleovorans CCR11 Carboxylesterase CaesCCR11, a New Member of Family XV.

A gene encoding a carboxylesterase produced by Geobacillus thermoleovoras CCR11 was cloned in the pET-3b cloning vector, sequenced and expressed in Escherichia coli BL21(DE3). Gene sequence analysis revealed an open reading frame of 750 bp that encodes a polypeptide of 250 amino acid residues (27.3 kDa) named CaesCCR11.
