Dynamics of annatto pigment synthesis and accumulation in seeds of Bixa orellana L. revealed by integrated chemical, anatomical, and RNA-Seq analyses.

Bixin is a commercially valuable apocarotenoid pigment found in the seed aril of Bixa orellana. The dynamics and regulation of its biosynthesis and accumulation during seed development remain largely unknown. Here, we combined chemical, anatomical, and transcriptomic data to provide stage-specific resolution of the cellular and molecular events occurring during B.

Intensive calcium monitoring improves outcomes on hungry bone syndrome in hyperparathyroidism.

Hungry bone syndrome (HBS) is a severe and underdiagnosed complication of parathyroidectomy in the treatment of primary hyperparathyroidism (PHP) and secondary hyper-parathyroidism to chronic kidney disease (SHP-CKD). A longitudinal study was conducted to compare the postoperative outcomes of patients who developed HBS in two different time frames: before and after implementing a protocol with an intensive electrolytic monitoring and an algorithm regarding electrolytic supplementation. Overall, 77 parathyroidectomies were included.

High-refined carbohydrate diet consumption induces neuroinflammation and anxiety-like behavior in mice.

Consumption of poor nutrients diets is associated with fat tissue expansion and with a central and peripheral low-grade inflammation. In this sense, the microglial cells in the central nervous system are activated and release pro-inflammatory cytokines that up-regulate the inducible nitric oxide synthase (iNOS), promoting Nitric Oxide (NO) production. The excess of NO has been proposed to facilitate anxious states in humans and rodents.

Selection and validation of reference genes for quantitative gene expression analyses in various tissues and seeds at different developmental stages in L.

L., popularly known as annatto, produces several secondary metabolites of pharmaceutical and industrial interest, including bixin, whose molecular basis of biosynthesis remain to be determined. Gene expression analysis by quantitative real-time PCR (qPCR) is an important tool to advance such knowledge.

Autonomously hyperfunctioning cystic nodule harbouring thyroid carcinoma - Case report and literature review.

Introduction: Hyperthyroidism is rarely associated with malignancy, but it cannot rule out thyroid cancer. Although there is published data describing this coexistence, thyroid carcinomas inside autonomously functioning nodules are uncommon.

Presentation Of Case: A 49-year-old woman presented with a cervical mass, unexplained weight loss and anxiousness, sweating and insomnia.

Primary thyroid lymphoma: A case report and review of the literature.

Introduction: A rapidly enlarging mass of the anterior compartment of the neck with compressive symptoms may represent, among other diagnosis, a neoplasm of the thyroid gland.

Presentation Of Case: We describe the case of a 59-year-old woman referred to the endocrine surgical unit because of compressive cervical symptoms for 3 months. The cervical ultrasound revealed a sub-sternal goiter with heterogeneous echo structure and the fine-needle aspirating cytology was inconclusive.

Isolation and purification of RNA from tissues rich in polyphenols, polysaccharides, and pigments of annatto (Bixa orellana L.).

The tropical plant Bixa orellana L. (annatto) produces an array of natural products, including the pigment bixin used in the food and cosmetics industries. In order to understand the biochemical and molecular basis of the biosynthesis of these natural products, a reliable method for isolating high yields of high-quality RNA is required.

[Hospitalized children' perceptions on exams].

The study had as objective to identify the hospitalized children's perception, in school age, about the accomplishment of exams. The research of descriptive nature was used, prevailing the investigation of qualitative character. The results revealed that the children cooperate with exams despite the fear.
