Adrenal dysfunction due to over-the-counter (OTC) health supplements containing unlabeled glucocorticoids has been previously reported. Here, we present a case series of 12 patients at an urban safety net medical center evaluated by endocrinology for iatrogenic adrenal dysfunction, Cushing syndrome (CS) and/or adrenal insufficiency (AI), associated with use of OTC arthritis supplements surreptitiously containing glucocorticoids. There were 12 patients using OTC arthritis supplements (Artri King [n = 8], Ardosons [n = 3], Ajo Rey [n = 1]) included.

The catalysis of nonredox reactions by external electric fields is one of the most rapidly expanding areas of chemistry. The Menshutkin reaction, a classic example of bimolecular nucleophilic substitution (S2), involves the conversion of a tertiary amine to a quaternary ammonium salt by coupling it with an alkyl halide. The reaction barrier of the Menshutkin reaction is theoretically predicted to be highly sensitive to the magnitude and direction of an external electric field experienced by the transition state.

In previous research, we created a model with homozygous mutations in calreticulin similar to those found in patients with essential thrombocythemia (ET) and primary myelofibrosis (PMF), two myeloproliferative neoplasms (MPNs). This model, lacking JAK orthologs, enabled us to examine the transcriptomic effects caused by mutant calreticulin without the influence of JAK/STAT activation, the primary pathogenic mechanism associated with calreticulin mutations known to date. Most of the gene expression changes observed seemed to be due to a partial loss of protein function, with the alteration of the extracellular matrix being particularly notable.

  • Sexual dimorphism in immunity shows that males and females have different immune responses, with females typically having stronger immunity due to oestrogens, while males are more prone to infections.
  • Research on fish, specifically yellowtail kingfish juveniles, indicates that males display significantly better innate immune responses compared to females, suggesting that females could be more susceptible to pathogens.
  • The study highlights the need for further exploration of sex-based immune differences in fish, which could inform breeding practices and disease management in aquaculture.

Nearly four decades have passed since IBM scientists pioneered atomic force microscopy (AFM) by merging the principles of a scanning tunneling microscope with the features of a stylus profilometer. Today, electrical AFM modes are an indispensable asset within the semiconductor and nanotechnology industries, enabling the characterization and manipulation of electrical properties at the nanoscale. However, electrical AFM measurements suffer from reproducibility issues caused, for example, by surface contaminations, Joule heating, and hard-to-minimize tip drift and tilt.

Rainbow trout is an important fish species for Peruvian artisanal aquaculture, comprising over 60 % of the total aquaculture production. However, their industry has been highly affected by several bacterial agents such as Yersinia ruckeri. This pathogen is the causative agent of Enteric Redmouth Disease, and causes high mortality in fingerlings and chronic infection in adult rainbow trout.

Essential thrombocythemia (ET) is a blood cancer caused by mutations in and . It is widely recognized that both mutations lead to the constitutive activation of JAK2/STAT signaling, although other JAK/STAT-independent pathogenic mechanisms triggered by these alterations have also been described in ET. In an attempt to study JAK2/STAT-independent mechanisms derived from mutations, our research group created a model with patient-like mutations in calreticulin that lacks JAK counterparts.

  • Hypothyroidism is a prevalent endocrine disorder that can lead to serious health issues, particularly in its severe form known as myxedema coma (MC), which is life-threatening and occurs less frequently.
  • This study compared clinical features and outcomes of patients with MC to those with hypothyroidism not experiencing MC, analyzing data from a large U.S. hospital database between 2016 and 2018.
  • Findings showed that patients with MC had significantly higher mortality rates (6.8% vs. 0.7%), longer hospital stays (9.64 days vs. 4.62 days), and higher healthcare costs ($21,768 vs. $8,941) compared to those without MC.

We present a case series of 3 patients who developed iatrogenic hypothalamic-pituitary-adrenal axis disruption while taking Artri King, an over-the-counter supplement marketed for joint pain that is reported to contain dexamethasone not listed on the supplement's label. Patient 1, a 58-year-old woman, presented with persistent hyponatremia, weight gain, proximal muscle weakness, dorsocervical fat pad, and new, red striae on her breast and abdomen in the setting of Artri King use. Her dexamethasone level was elevated (Table 1), confirming the suspicion of dexamethasone content in this supplement.

Galinstan is the brand name for a low-melting gallium-based alloy, which is a promising nontoxic alternative to mercury, the only elemental metal found in the liquid state at room temperature. Liquid alloys such as Galinstan have found applications as electromechanical actuators, sensors, and soft contacts for molecular electronics. In this work, we validate the scope of Galinstan top contacts to probe the electrical characteristics of Schottky junctions made on Si(111) and Si(211) crystals modified with Si-C-bound organic monolayers.

Background: Decreasing medication burden with raltegravir plus lamivudine in virologically suppressed persons with HIV (PWH) maintained efficacy and was well tolerated at 24 weeks, but more comprehensive data over longer follow-up are required.

Methods: Prospective 48 week extension phase of the raltegravir plus lamivudine arm from a previous 24 week pilot randomized clinical trial in which virologically suppressed PWH were randomized 2:1 to switch to fixed-dose combination 150 mg lamivudine/300 mg raltegravir twice daily or to continue therapy. In this 48 week extension phase, raltegravir was dosed at 1200 mg/day and lamivudine 300 mg/day.

  • Reliable maps of species distributions, like the IUCN range maps, are crucial for biodiversity research but often don't match actual occurrence data.
  • A study found that camera traps detected only 39% of expected species based on IUCN and recent area of habitat (AOH) maps, with most mismatches occurring near range edges.
  • The findings highlight that while range maps may not miss areas where species exist, they often include areas where species are absent, stressing the need to combine maps with ground-based data for better conservation planning.

In recent years, the hybrid silicon-molecular electronics technology has been gaining significant attention for applications in sensors, photovoltaics, power generation, and molecular electronics devices. However, Si-H surfaces, which are the platforms on which these devices are formed, are prone to oxidation, compromising the mechanical and electronic stability of the devices. Here, we show that when hydrogen is replaced by deuterium, the Si-D surface becomes significantly more resistant to oxidation when either positive or negative voltages are applied to the Si surface.
