Maternal adiponectin restores cholinergic vasodilation in resistance vessels from adult offspring exposed to maternal obesity .

Maternal obesity increases the risk of cardiovascular and metabolic disease in the offspring both during childhood and adult life. Pregnant women and mice with obesity have lower circulating levels of adiponectin (ADN) compared to lean controls. ADN is an adipokine involved in regulating energy metabolism, vascular function, and placental function.

Identification of novel candidate predisposing genes in familial nonmedullary thyroid carcinoma implicating DNA damage repair pathways.

The genetic basis of nonsyndromic familial nonmedullary thyroid carcinoma (FNMTC) is still poorly understood, as the susceptibility genes identified so far only account for a small percentage of the genetic burden. Recently, germline mutations in DNA repair-related genes have been reported in cases with thyroid cancer. In order to clarify the genetic basis of FNMTC, 94 genes involved in hereditary cancer predisposition, including DNA repair genes, were analyzed in 48 probands from FNMTC families, through targeted next-generation sequencing (NGS).

Naming hypoglycemia: a narrative tool for young people with type 1 diabetes and their families.

Objective: Hypoglycemia constitutes a communication barrier between youth with type 1 diabetes, their family members and health professionals. A narrative tool may contribute to a more effective communication.

Methods: Semi-structured interviews with six open-ended questions using narrative techniques collect and analyze (thematic and comparative analysis) different ways of "naming" the lived experience of hypoglycemia.

Trophoblast-specific overexpression of the LAT1 increases transplacental transport of essential amino acids and fetal growth in mice.

Placental System L amino acid transporter activity is decreased in pregnancies complicated by intrauterine growth restriction (IUGR) and increased in fetal overgrowth. However, it is unknown if changes in the expression/activity of placental Large Neutral Amino Acid Transporter Small Subunit 1 (Slc7a5/LAT1) are mechanistically linked to placental function and fetal growth. We hypothesized that trophoblast-specific overexpression increases placental transport of essential amino acids, activates the placental mechanistic target of rapamycin (mTOR) signaling, and promotes fetal growth in mice.

Claudin-4 Modulates Autophagy via SLC1A5/LAT1 as a Mechanism to Regulate Micronuclei.

Unlabelled: Genome instability is a hallmark of cancer crucial for tumor heterogeneity and is often a result of defects in cell division and DNA damage repair. Tumors tolerate genomic instability, but the accumulation of genetic aberrations is regulated to avoid catastrophic chromosomal alterations and cell death. In ovarian cancer tumors, claudin-4 is frequently upregulated and closely associated with genome instability and worse patient outcomes.

Pregnant women's knowledge and clinical management of hemolytic disease of the fetus and newborn in Pará, Brazil.

Objective: To evaluate the knowledge of pregnant women and the clinical management of hemolytic disease of the fetus and newborn, as well as to describe the gestational profile, risk factors and socio-epidemiological profile of pregnant women treated at two municipal health units in Belém (Pará, Brazil).

Methods: This was a cross-sectional analytical study, which consisted in the application of questionnaires to pregnant women who underwent prenatal care at the municipal health units.

Results: A total of 104 pregnant women were evaluated; most were aged between 24 and 29 years old, had high school degrees (38 %), family incomes between 1 and 2 minimum wages (45 %) and blood type O+ (43 %).

A Case of Amyloid Goitre in Heavy Chain Amyloidosis: Diagnostic Challenges and Clinical Implications.

Unlabelled: Immunoglobulin heavy chain amyloidosis (AH amyloidosis) is an extremely rare subtype of immunoglobulin-derived amyloidosis and there is limited literature on how to diagnose and manage this disorder. We describe a rare case of AH amyloidosis with amyloid goitre and the importance of mass spectrometry in the identification of the different types of amyloids. While additional studies are needed, several observations suggest important practical implications, including differences in clinical picture, prognosis, and pathologic diagnosis.

Analysis of survival rate and persistence predictors of baricitinib in real-world data from a large cohort of rheumatoid arthritis patients.

Objectives: The persistence in therapy of rheumatoid arthritis drugs and particularly bDMARD is a limiting factor for their long-term use. The randomized controlled trials (RCTs) may not reflect real-world contexts due to strict inclusion and exclusion criteria. Baricitinib, which targets both JAK1 and JAK2, has been used in Italy for several years.

Overexpression of the LAT1 in primary human trophoblast cells increases the uptake of essential amino acids and activates mTOR signaling.

The System L amino acid transporter, particularly the isoform Large Neutral Amino Acid Transporter Small Subunit 1 (LAT1) encoded by SLC7A5, is believed to mediate the transfer of essential amino acids in the human placenta. Placental System L amino acid transporter expression and activity is decreased in pregnancies complicated by IUGR and increased in fetal overgrowth. However, it remains unknown if changes in the expression of LAT1 are mechanistically linked to System L amino acid transport activity.

Female sexual dysfunction in an outpatient andrology clinic-A therapeutic opportunity?

Introduction: The sexual life of a couple is a dynamic entity, in which the two influence each other mutually, thus the existence of female sexual dysfunction (FSD) can influence the treatment of the man who seeks clinical help. Identify sexual dysfunction in female partners of patients attending an andrology clinic may provide a therapeutic opportunity. The authors aim to assess proportion of FSD in this population by comparison with a control group.

Maternal obesity alters the placental transcriptome in a fetal sex-dependent manner.

Infants born to obese mothers have an increased risk of developing obesity and metabolic diseases in childhood and adulthood. Although the molecular mechanisms linking maternal obesity during pregnancy to the development of metabolic diseases in offspring are poorly understood, evidence suggests that changes in the placental function may play a role. Using a mouse model of diet-induced obesity with fetal overgrowth, we performed RNA-seq analysis at embryonic day 18.

Placental Remote Control of Fetal Metabolism: Trophoblast mTOR Signaling Regulates Liver IGFBP-1 Phosphorylation and IGF-1 Bioavailability.

The mechanisms mediating the restricted growth in intrauterine growth restriction (IUGR) remain to be fully established. Mechanistic target of rapamycin (mTOR) signaling functions as a placental nutrient sensor, indirectly influencing fetal growth by regulating placental function. Increased secretion and the phosphorylation of fetal liver IGFBP-1 are known to markedly decrease the bioavailability of IGF-1, a major fetal growth factor.

Maternal glucagon-like peptide-1 is positively associated with fetal growth in pregnancies complicated with obesity.

Pregnant women with obesity are more likely to deliver infants who are large for gestational age (LGA). LGA is associated with increased perinatal morbidity and risk of developing metabolic disease later in life. However, the mechanisms underpinning fetal overgrowth remain to be fully established.

Caloric restriction as a possible pitfall for persistent acromegaly follow-up - case report.

Background: Acromegaly diagnosis is established when plasma levels of IGF-1 are increased and the Oral Glucose Tolerance Test (OGTT) with 75gr of glucose can't suppress Growth Hormone (GH) levels. These two parameters are also useful during follow-up, after surgical/radiologic therapy and/or during medical therapy.

Case Presentation: A 29-year-old woman was diagnosed with acromegaly after a severe headache.

[A Cognitive Behavioural-Based Intervention in Reducing Test Anxiety in High School Students: A Pilot Cluster Randomized Controlled Trial].

Introduction: School-age test anxiety is an important risk factor for school performance. Notwithstanding, few studies seek to identify which strategies are effective in improving test anxiety. The aim of this study was to assess whether a cognitive-behavioural intervention for high school students could significantly reduce test anxiety.

Assessing the toxicity of airborne (nano)particles to the human respiratory system: from basic to advanced models.

Several studies have been conducted to address the potential adverse health risks attributed to exposure to nanoscale materials. While studies are fundamental for identifying the relationship between dose and occurrence of adverse effects, model systems provide important information regarding the mechanism(s) of action at the molecular level. With a special focus on exposure to inhaled (nano)particulate material toxicity assessment, this review provides an overview of the available human respiratory models and exposure systems for testing, advantages, limitations, and existing investigations using models of different complexity.

A novel technique using chronic infusion of small extracellular vesicles from gestational diabetes mellitus causes glucose intolerance in pregnant mice.

Small extracellular vesicles (sEVs) play a central role in cell-to-cell communication in normal physiology and in disease, including gestational diabetes mellitus (GDM). The goal of the present study was to test the hypothesis that chronic administration of sEVs isolated from GDM causes glucose intolerance in healthy pregnant mice. Small EVs were isolated from plasma between 24 and 28 weeks gestation from healthy pregnant women (controls) and GDM, and infused intravenously for 4 days in late pregnant mice using a mini-osmotic pump.

Effect of obesity on fragility fractures, BMD and vitamin D levels in postmenopausal women. Influence of type 2 diabetes mellitus.

Aims: To see the effects of obesity on risk fracture, bone density (BMD), and vitamin D levels in a group of postmenopausal women, and consider how comorbid type 2 diabetes mellitus (T2DM) modifies them.

Methods: 679 postmenopausal women were grouped into obese and non-obese. Obese women were grouped into those with T2DM and those without.

Normalization of maternal adiponectin in obese pregnant mice prevents programming of impaired glucose metabolism in adult offspring.

Infants born to obese mothers have a greater risk for childhood obesity and insulin resistance. However, the underlying biological mechanism remains elusive, which constitutes a significant roadblock for developing specific prevention strategies. Maternal adiponectin levels are lower in obese pregnant women, which is linked with increased placental nutrient transport and fetal overgrowth.

Impact of Particle Size on Toxicity, Tissue Distribution and Excretion Kinetics of Subchronic Intratracheal Instilled Silver Nanoparticles in Mice.

The unique physicochemical properties of silver nanoparticles (AgNPs) make them useful in a wide range of sectors, increasing their propensity for human exposure, as well as the need for thorough toxicological assessment. The biodistribution of silver, hematological parameters and GSH/GSSG levels in the lung and liver were studied in mice that were intratracheally instilled with AgNP (5 and 50 nm) and AgNO once a week for 5 weeks, followed by a recovery period of up to 28 days (dpi). Data was gathered to build a PBPK model after the entry of AgNPs into the lungs.

Maternal obesity causes fetal cardiac hypertrophy and alters adult offspring myocardial metabolism in mice.

Obesity in pregnant women causes fetal cardiac dysfunction and increases offspring cardiovascular disease risk, but its effect on myocardial metabolism is unknown. We hypothesized that maternal obesity alters fetal cardiac expression of metabolism-related genes and shifts offspring myocardial substrate preference from glucose towards lipids. Female mice were fed control or obesogenic diets before and during pregnancy.

In Vitro Hepatotoxic and Neurotoxic Effects of Titanium and Cerium Dioxide Nanoparticles, Arsenic and Mercury Co-Exposure.

Considering the increasing emergence of new contaminants, such as nanomaterials, mixing with legacy contaminants, including metal(loid)s, it becomes imperative to understand the toxic profile resulting from these interactions. This work aimed at assessing and comparing the individual and combined hepatotoxic and neurotoxic potential of titanium dioxide nanoparticles (TiONPs 0.75-75 mg/L), cerium oxide nanoparticles (CeONPs 0.

Gibbs Sampling Detection for Large MIMO and MTC Uplinks with Adaptive Modulation.

Wireless networks beyond 5G will mostly be serving myriads of sensors and other machine-type communications (MTC), with each device having different requirements in respect to latency, error rate, energy consumption, spectral efficiency or other specifications. Multiple-input multiple-output (MIMO) systems remain a central technology towards 6G, and in cases where massive antenna arrays or cell-free networks are not possible to deploy and only moderately large antenna arrays are allowed, the detection problem at the base-station cannot rely on zero-forcing or matched filters and more complex detection schemes have to be used. The main challenge is to find low complexity, hardware feasible methods that are able to attain near optimal performance.
