The effect of novel β-lactam derivatives synthesized from substituted phenethylamines on resistance genes of MRSA isolates.

This study focuses on the activity of previously reported imine and β-lactam derivatives against methicillin-resistant Staphylococcus aureus (MRSA) isolates. The presence of mecA and blaZ genes in the isolates was determined, and the minimum inhibitory concentration (MIC) values were determined based on the antibacterial activity against these isolates. Active compounds were selected and their ability to act against resistant isolates in vitro was determined.

Retinoic acid reduces kidney injury by regulating oxidative stress, NRF-2, and apoptosis in hyperoxic mice.

Nuclear factor-erythroid-2-related factor-2 (NRF-2) is a cellular resistance protein to oxidants. We investigated the effect of exogenous all-trans retinoic acid (ATRA) on the antioxidant system and NRF-2 in mice kidneys under hyperoxia-induced oxidative stress. Mice were divided into four groups.

Is it possible to predict Surgical Site Infection?

Introduction: Surgical site infection (SSI) is a widely seen postoperative complication that causes a decrease in life quality and an economic burden. In this study, we aim to find the predictive values of preoperative and postoperative neutrophile lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) values for SSI.

Methods: In this retrospective study, 698 patients who had total abdominal hysterectomy operations with benign indications and confirmed histopathological results were accessed.

Evaluation of Fatty Acid Contents and Biological Activities of Jurinea turcica.

The fatty acid profile, antioxidant/antibacterial, and cytotoxic effects of the extracts obtained from Jurinea turcica B.Doğan& A.Duran have been evaluated for the first time in the current study.

Garlic Exosomes Promote Hair Growth Through the Wnt/β-catenin Pathway and Growth Factors.

Background Exosomes are membrane-derived nanovesicles produced by cells and play an important role in intercellular communication. Objectives This study aimed to investigate the effects of garlic exosome (GE) on hair growth. Methods Forty-two Sprague-Dawley/Wistar albino rats were randomly divided into six groups: non-shaved control, shaved control, topical control, GE 2 mg, GE 4 mg, and topical GE.

Effect of Solanum lycopersicum and Citrus limon-Derived Exosome-Like Vesicles on Chondrogenic Differentiation of Adipose-Derived Stem Cells.

Articular cartilage defect treatment is a very important problem because its therapeutic options are not successful enough. Due to the weak self-repairing capacity of the avascular cartilage, even minor damage can progress and cause joint damage leading to osteoarthritis. Although various treatment strategies have been developed to repair damaged cartilage, cell- and exosome-based therapies are promising.

Substituted phenethylamine-based β-lactam derivatives: Antimicrobial, anticancer, and β-lactamase inhibitory properties.

In this study, a series of novel β-lactam derivatives were synthesized with yields ranging from 41 % to 91 %, and their antimicrobial activities were investigated against bacterial and fungal isolates that cause nosocomial infections. The results revealed that the novel β-lactam derivatives, especially compound 19, showed antibacterial activities ranging from 0.98 to 250 µg/mL.

The apoptotic effect of ozone therapy on mitochondrial activity of highly metastatic breast cancer cell line MDA-MB-231 using in vitro approaches.

Ozone (O) gas is the triatomic state of oxygen and it is used as a disinfection agent due to its strong oxidizing effect, since its discovery in the mid-nineteenth century. Ozone therapy is also an alternative therapeutic approach for some diseases like circulatory disorders, AIDS, asthma, cardiovascular diseases, and certain types of cancer by increasing the oxygen levels in the blood by external addition of ozone to the body. In this study, the therapeutic potential of ozone therapy was examined by inhibiting the growth of breast cancer cells in a dose-dependent procedure.

Dysregulation of E-cadherin in pulmonary cell damage related with COPD contributes to emphysema.

Air pollution, especially at chronic exposure to high concentrations, is a respiratory risk factor for the development of chronic obstructive pulmonary disease (COPD). E-cadherin, a cell-cell adhesion protein, is involved in the integrity of the alveolar epithelium. Causes of E-cadherin decreases in emphysematous areas with pulmonary cell damage related to COPD are not well understood.

Atorvastatin attenuates pulmonary fibrosis in mice and human lung fibroblasts, by the regulation of myofibroblast differentiation and apoptosis.

Statins have anti-inflammatory and antifibrotic effects in addition to cholesterol-lowering effect. We aimed to investigate the effect of atorvastatin (ATR) in fibrotic mouse lung and human lung fibroblasts (MRC5s). Pulmonary fibrosis was induced by a single dose of bleomycin by intratracheal instillation in adult mice.

Garlic (Allium sativum)-derived SEVs inhibit cancer cell proliferation and induce caspase mediated apoptosis.

As a key component of the cell-to-cell communication, small extracellular vesicles (SEVs) released from various sources are known to be affecting the physiological conditions of the target cells. Although it has been suggested that edible plant-derived nanoparticles contributes to the cross kingdom communication with the mammalian cells, the effect of these particles on cancer cell progression still needs a further exploration. Here, we isolated and then characterized garlic derived SEVs by nanoparticle tracking analysis, electron microscopy and SEV surface antibodies.

Cold Denaturation of Proteins: Where Bioinformatics Meets Thermodynamics to Offer a Mechanistic Understanding: Pea Protein As a Case Study.

Protein structure can be altered with heat, but models which predict denaturation show that globular proteins also spontaneously unfold at low temperatures through cold denaturation. By an analysis of the primary structure of pea protein using bioinformatic modeling, a mechanism of pea protein cold denaturation is proposed. Pea protein is then fractionated into partially purified legumin and vicilin components, suspended in ethanol, and subjected to low temperatures (-10 to -20 °C).

Effect of long noncoding RNAs on epithelial-mesenchymal transition in A549 cells and fibrotic human lungs.

Long noncoding RNAs (LncRNAs) regulate epithelial-mesenchymal transition (EMT). EMT involves myofibroblast differentiation and pulmonary fibrosis (PF). We aimed to determine the expression profiles of HOTAIR, CARLo-5, and CD99P1 LncRNAs in EMT-mediated myofibroblast differentiation in A549 cells and fibrotic human lungs and to explain their roles.

Impact of Prepartum Body Condition Score Loss on Metabolic Status During the Transition Period and Subsequent Fertility in Brown Swiss Dairy Cows.

Introduction: The objectives of this study were to determine the role of a fall in pre-calving body condition score (BCS) in postpartum metabolic status and reproductive outcomes, and gauge the indicativeness of blood metabolites during the transition period.

Material And Methods: Cows were grouped based on BCS loss between days -14 ±3 and 0 relative to calving. Cows that lost no BCS were the BCS control group (BCS-C), cows that lost 0.

The effects of atorvastatin on the kidney injury in mice with pulmonary fibrosis.

Objectives: The present study investigated the effects of atorvastatin on kidney injury in mice with pulmonary fibrosis (PF).

Methods: Adult mice were divided into four groups: mice treated with intratracheal bleomycin (I) and their controls (II), and mice treated with atorvastatin for 10 days after 7 days from bleomycin treatment (III) and their controls (IV). Mice were dissected on the 21st day.

Rheology, particle-size distribution, and stability of low-fat mayonnaise produced via double emulsions.

In this study, the effects of the double emulsification method on the rheological properties, particle size, and stability of low-fat mayonnaise were studied. Different water-phase-to-oil ratios (2:8 and 4:6) of primary emulsions and different stabilizer types (sodium caseinate, xanthan gum, and lecithin-whey protein concentrate) were used to produce double-emulsified mayonnaise. As a control sample, mayonnaise was prepared conventionally.
