Background: Rare variants in melanocortin 4 receptor gene (MC4R) result in a severe form of early-onset obesity; however, it is unclear how these variants may affect abdominal fat distribution, intrahepatic fat accumulation, and related metabolic sequelae.

Methods: Eight hundred seventy-seven youth (6-21 years) with overweight/obesity, recruited from the Yale Pediatric Obesity Clinic in New Haven, CT, underwent genetic analysis to screen for functionally damaging, rare variants (MAF < 0.01) in MC4R.

Obesity is one of the leading causes of the development of insulin resistance, diabetes, and metabolic dysfunction-associated steatotic liver disease (MASLD) in children. With the progression of insulin resistance, both glucose and free fatty acid (FFA) plasma levels are elevated, leading to cardiometabolic complications such as impaired glucose tolerance (IGT), type 2 diabetes, and liver fat accumulation. In this study, oral minimal models were used to estimate insulin sensitivity indexes (SI and SI) in 375 adolescents with obesity.

Article Synopsis
  • Vein of Galen malformations are congenital issues treated mainly through endovascular embolization, but challenges arise in patients with venous blockages that can lead to complications.
  • A study reviewed pediatric cases where an intracranial venous sinus stent was used to enhance blood flow following transvenous embolization, improving outcomes.
  • Results showed that all three patients experienced successful treatment with normal venous drainage post-procedure, although one had a temporary nerve issue unrelated to the stent.

Background: Lactate is not considered just a "waste product" of anaerobic glycolysis anymore. It has been proved to play a key role in several metabolic diseases, such as in the metabolic dysfunction-associated steatotic liver disease, obesity, and diabetes. The capability of simulating glucose-insulin-lactate interaction would be useful to design and test drugs targeting lactate metabolism in such pathological conditions.

Aim: In this study, we investigated glucose and lactate kinetics during a 75 g oral glucose tolerance test (OGTT) in 23 overweight and obese adolescents and assessed putative differences among participants with and without metabolic dysfunction-associated steatotic liver disease (MASLD).

Methods: We enrolled 23 young people (six girls) with obesity [body mass index 33 (29-37)]. Glucose-lactate kinetics parameters (disposal glucose insulin sensitivity, SI; fraction of glucose converted into lactate, fr; fractional lactate clearance rate, k) and lactate production rate (LPR) were estimated using the oral glucose-lactate minimal model.

Background: Insulin-naive subjects with type 2 diabetes (T2D) start basal insulin titration from a low initial insulin dose (IID), which is adjusted weekly or twice per week based on fasting plasma glucose (FPG) measurement as recommended by the American Diabetes Association (ADA). The procedure to reach the optimal insulin dose (OID) is time-consuming, especially in subjects with high insulin needs (HIN). The aim of this study is to provide a fast and effective, but still safe, insulin titration algorithm in insulin-naive T2D subjects with HIN.

Objective: The Padova type 2 diabetes (T2D) simulator (T2DS) has been recently proposed to optimize T2D treatments including novel long-acting insulins. It consists of a physiological model and an in silico population describing glucose dynamics, derived from early-stage T2D subjects studied with sophisticated tracer-based experimental techniques. This limits T2DS domain of validity to this specific sub-population.

Patients with vein of Galen malformations (VOGMs) can develop fine angiogenic networks with fistulous connections to the precursor of the vein of Galen. In these cases, transarterial embolization (TAE) with liquid embolic agents (LEAs) is challenging due to reflux in the pedicle leading to the network, causing poor penetration. Transvenous approaches carry a risk of hemorrhage from pathologic vasculature.

Article Synopsis
  • Clear-cutting, a common forestry practice, affects the soil fungal community in managed forests, but stand-level variations, particularly at the edge of clear-cuts, are not well understood.
  • Soil sampling from clear-cuts and surrounding areas showed small differences in fungal community composition and diversity, with the clear-cut zone having fewer ectomycorrhizal species but similar richness and evenness compared to the edge and forest zones.
  • Despite lower fungal biomass in clear-cuts, other soil properties like organic matter, pH, nitrogen, and phosphorus remained consistent across all zones, indicating that small-scale clear-cutting can maintain comparable soil fungal communities over the medium term.

Introduction: Although there is an abnormal presentation of Niacin Response Syndrome (ANRS) in schizophrenic patients (SZ) compared to subjects with other psychiatric illnesses and with healthy individuals. However, most of the literature is based on studies that have used tests of niacin topical administration, observing, on the other hand, less scientific production of its oral administration. The objective was to determine the sensitivity of the oral niacin test as a method of detecting ASRN in EZ.

Assessing free fatty acids (FFAs) kinetics and the role of insulin and glucose on FFA lipolysis and disposal may improve our understanding of the pathogenesis of type 2 diabetes (T2D). Some models have been proposed to describe FFA kinetics during an intravenous glucose tolerance test and only one during an oral glucose tolerance test. Here, we propose a model of FFA kinetics during a meal tolerance test and use it to assess possible differences in postprandial lipolysis in individuals with type 2 diabetes (T2D) and individuals with obesity without type 2 diabetes (ND).

Immune checkpoint blockade (ICB) with antibodies has shown durable clinical responses in a wide range of cancer types, but the overall response rate is still limited. Other effective therapeutic modalities to increase the ICB response rates are urgently needed. New bispecific antibody (bsAb) formats combining the ICB effect and a direct action on cancer cells could improve the efficacy of current immunotherapies.

Understorey vegetation plays a key role in Mediterranean forest ecosystem functioning. However, we still lack a thorough understanding of the patterns and drivers of understorey composition and diversity. As a result, understoreys are often ignored during assessments of forest functioning under climate change.

De novo protein design enables the exploration of novel sequences and structures absent from the natural protein universe. De novo design also stands as a stringent test for our understanding of the underlying physical principles of protein folding and may lead to the development of proteins with unmatched functional characteristics. The first fundamental challenge of de novo design is to devise "designable" structural templates leading to sequences that will adopt the predicted fold.

Global warming is pushing populations outside their range of physiological tolerance. According to the environmental envelope framework, the most vulnerable populations occur near the climatic edge of their species' distributions. In contrast, populations from the climatic center of the species range should be relatively buffered against climate warming.
