Water stress modulates terpene biosynthesis and morphophysiology at different ploidal levels in Lippia alba (Mill.) N. E. Brown (Verbenaceae).

Monoterpenes are the main component in essential oils of Lippia alba. In this species, the chemical composition of essential oils varies with genome size: citral (geraniol and neral) is dominant in diploids and tetraploids, and linalool in triploids. Because environmental stress impacts various metabolic pathways, we hypothesized that stress responses in L.

In vitro evaluation of barium titanate nanoparticle/alginate 3D scaffold for osteogenic human stem cell differentiation.

Nanomaterials can mimic properties of extracellular matrix molecules, promising great potential for scaffold composition in tissue engineering. In the present study, we investigated whether barium titanate nanoparticles (BT NP) combined with alginate polymer would provide a new cytocompatible three-dimensional (3D) scaffold to induce osteogenic stem cell differentiation. In vitro cytocompatibility and osteogenic differentiation potential were investigated using human mesenchymal stem cells (MSC).

Cardiophrenic lymph node resection in cytoreduction for primary advanced or recurrent epithelial ovarian carcinoma: a cohort study.

Objectives: To evaluate the clinical outcomes of epithelial ovarian carcinoma patients who underwent cardiophrenic lymph node resection.

Methods: We retrospectively reviewed the records of all surgically treated patients with advanced epithelial ovarian carcinoma (stages IIIC-IV) who underwent cardiophrenic lymph node resection between 2002 and 2018. Only those in whom cardiophrenic lymph node involvement was the only detectable extra-abdominal disease were included.

Proposing the use of dental pulp stem cells as a suitable biological model of neurofibromatosis type 1.

Purpose: This study aims to propose the dental pulp stem cells (DPSCs) as a model for studying two features related to neurofibromatosis type 1 (NF1), i.e. augmented proliferative capacity and altered osteogenic differentiation.

Strategies and molecular tools to fight antimicrobial resistance: resistome, transcriptome, and antimicrobial peptides.

The increasing number of antibiotic resistant bacteria motivates prospective research toward discovery of new antimicrobial active substances. There are, however, controversies concerning the cost-effectiveness of such research with regards to the description of new substances with novel cellular interactions, or description of new uses of existing substances to overcome resistance. Although examination of bacteria isolated from remote locations with limited exposure to humans has revealed an absence of antibiotic resistance genes, it is accepted that these genes were both abundant and diverse in ancient living organisms, as detected in DNA recovered from Pleistocene deposits (30,000 years ago).

Bisphosphonate-related osteonecrosis of the jaws--an initial case series report of treatment combining partial bone resection and autologous platelet-rich plasma.

Purpose: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a well-recognized pathologic entity that is challenging and difficult to manage. Recent literature contains several articles, with most recommending conservative management. This report describes a treatment modality for advanced cases of BRONJ that involves bone resection and autologous platelet-rich plasma (PRP).

Identification of botryticidal proteins with similarity to NBS-LRR proteins in rosemary pepper (Lippia sidoides Cham.) flowers.

Heavy agricultural losses are closely related to attacks by insect-pests and phytopathogens such as bacteria and fungi. Among them, the fungus Botrytis cinerea can cause gray mold in more than 200 different species of plants, and is considered a challenging problem for agribusiness. Fungicides are commonly used to control this pathogen because they are fast-working and easy to apply.

Identification of a Passiflora alata Curtis dimeric peptide showing identity with 2S albumins.

Antifungal proteins and peptides, essential compounds for plant defense, have been isolated from several tissues of various plants. These proteins could be used as a natural alternative to control phytopathogenic fungi. In this report a heterodimeric antifungal protein named Pa-AFP1, showing higher identity with the 2S albumin family, was purified by using 70-100% ammonium sulfate saturation and further purification steps such as anionic exchange Q-Sepharose chromatography associated with HPLC reversed-phase C4 chromatography.

Role of SERK genes in plant environmental response.

In plants, cell signaling connects the environmental input to the intracellular responses in plants. Exogenous signals play an important role in cell metabolism leading to growth and defense responses. Some of these stimuli induce anatomical and physiological modifications that are generally modulated by gene expression.
