Molecular genetic association of rs8099917 and rs1800795 polymorphisms in the progression of hepatitis Delta virus liver disease.

Background: The relationship between viral infections and host factors holds high hopes for identifying the role of Interferon Lambda 3 (IFNL3) and Interleukin 6 (IL-6) polymorphisms in the development of Chronic Liver Disease (CLD) in patients infected with hepatitis Delta virus (HDV) in the Western Brazilian Amazon.

Methods: Cross-sectional study conducted with a cohort of 40 chronic HDV patients, 27 with CLD and 13 without evident liver damage. Biological samples from the participants were analyzed using the polymerase chain reaction (PCR) technique, followed by sequencing by the automated Sanger method.

Maltodextrin as a Drying Adjuvant in the Lyophilization of Tropical Red Fruit Blend.

Guava, pitanga and acerola are known for their vitamin content and high levels of bioactive compounds. Thus, the preparation of combinations of these fruits comprises a blend with high nutraceutical potential, yielding a strong and attractive pigmentation material. In this study, the influence of different proportions of maltodextrin on the lyophilization of a blend of guava, acerola and pitanga was evaluated considering not only the physicochemical, physical and colorimetric parameters but also the bioactive compounds in the obtained powders.

Physicochemical Aspects, Bioactive Compounds, Phenolic Profile and In Vitro Antioxidant Activity of Tropical Red Fruits and Their Blend.

The combination of fruit pulps from different species, in addition to multiplying the offer of flavors, aromas and textures, favors the nutritional spectrum and the diversity of bioactive principles. The objective was to evaluate and compare the physicochemical characteristics, bioactive compounds, profile of phenolic compounds and in vitro antioxidant activity of pulps of three species of tropical red fruits (acerola, guava and pitanga) and of the blend produced from the combination. The pulps showed significant values of bioactive compounds, with emphasis on acerola, which had the highest levels in all parameters, except for lycopene, with the highest content in pitanga pulp.

Remission of primary hyperparathyroidism after fine needle aspiration of a parathyroid nodule mistaken for a thyroid nodule.

Primary hyperparathyroidism (PHPT) is an endocrine disorder characterized by hypercalcaemia and elevated or inappropriately normal concentrations of parathyroid hormone. Remission of PHPT caused by infarction or hemorrhage of a parathyroid adenoma rarely occurs, either spontaneously or induced, not always leading to a definitive cure. We report a case of 72-year-old women with primary hyperparathyroidism who underwent fine-needle aspiration cytology (FNAC) of a parathyroid adenoma mistaken for a thyroid nodule followed by normalization of parathyroid hormone (PTH) and serum calcium levels.

Smelling Peppers and Pout Submitted to Convective Drying: Mathematical Modeling, Thermodynamic Properties and Proximal Composition.

Pepper ( spp.) is among the oldest and most cultivated crops on the planet. Its fruits are widely used as natural condiments in the food industry for their color, flavor, and pungency properties.

Neural correlates of lexical stress processing in a foreign free-stress language.

Introduction: The paper examines the discrimination of lexical stress contrasts in a foreign language from a neural perspective. The aim of the study was to identify the areas associated with word stress processing (in comparison with vowel processing), when listeners of a fixed-stress language have to process stress in a foreign free-stress language.

Methods: We asked French-speaking participants to process stress and vowel contrasts in Spanish, a foreign language that the participants did not know.

Multiple Brown Tumors Secondary to Parathyroid Carcinoma: A Challenging Diagnosis.

Parathyroid carcinoma is an extremely rare endocrine neoplasm that accounts for less than 1% of the cases of primary hyperparathyroidism (PHPT). Continuous exposure to high levels of parathyroid hormone (PTH) induces an increase in bone remodeling and patients may present with osteitis fibrosa cystica, which is characterized by subperiosteal resorption of the phalanges, diffuse osteopenia, salt and pepper appearance of the skull, bone cysts, and brown tumors. Brown tumors occur in less than 5% of all patients with any form of hyperparathyroidism.

Genomic Variability of Hepatitis B Virus Circulating in Brazilian Western Amazon.

The emergence of clinically relevant mutations in the hepatitis B virus (HBV) genome has been a matter of great debate because of the possibility of escape from the host's immune system, the potential to cause more severe progression of liver diseases and the emergence of treatment-resistant variants. Here we characterized the circulating variants of HBV in Rondônia State, in the north of Brazil. Serum samples of 62 chronic HBV carriers were subjected to PCR assays and clinical data were collected.

New onset autoimmune diabetes mellitus and hypothyroidism secondary to pembrolizumab in a patient with metastatic lung cancer.

Summary: Immunotherapy has become an important pillar for the management of advanced cancer. Immune-related adverse events including endocrinopathies have been well described with programmed cell death 1 inhibitors such as pembrolizumab. While thyroid dysfunction is the most common endocrinopathy associated with pembrolizumab, new-onset autoimmune diabetes mellitus (DM) is extremely rare.

Ovarian Leydig cell tumor and postmenopausal hirsutism with signs of virilisation.

A 71-year-old woman was referred to the endocrinology clinic to investigate postmenopausal hirsutism with 10 years of evolution. She had history of regular menses and menopause with 50 years old. Physical examination showed a male pattern facies, deepening of the voice, androgenic alopecia and hirsutism with a score of 23 according to the modified Ferriman-Gallwey scale.

Effect of the Combination of Superabsorbent Polymers for Autogenous Shrinkage Control with Steel Fibers of High-Performance Concrete under Uniaxial Tension Using DIC.

This paper presents a study of the effect of a superabsorbent polymer (SAP) for autogenous shrinkage control on the uniaxial tensile behavior of steel fiber reinforced concrete (SFRC). The use of fibers and SAP potentially increases the durability of the concrete, preventing cracking by autogenous shrinkage and enhancing post-cracking behavior. Furthermore, SAP can provide further hydration for self-healing purposes and improve the ductility of the SFRC.

Bone alkaline phosphatase besides intact parathyroid hormone in hemodialysis patients--any advantage?

Background/aim: Bone alkaline phosphatase (bAP) is known to be an important biochemical marker of bone formation. Through the present study, we intended to find out whether there is any advantage in bAP determination, as a routine biochemical marker, besides intact parathyroid hormone (iPTH) in hemodialysis patients.

Methods: In a population of 140 hemodialysis patients, bAP and iPTH were determined on four quarterly consecutive occasions.
