Summary: Mood alterations, anxiety, and cognitive impairments associated with adult-onset hypothyroidism often persist despite replacement treatment. A study using a pharmacological hypothyroid mouse model found that augmenting levothyroxine (L-T-4) with 3-iodothyronamine (T(1)AM) may improve behavioral correlates of depression, anxiety, and memory and has an effect on hippocampal neurogenesis. However, L-T-4 alone was sufficient for recovering memory and hippocampal neurogenesis deficits associated with hypothyroidism, while non-canonical thyroid hormone (TH) signaling did not play a significant role.

Summary: Surface ligand modification and stiffness adjustment significantly enhance bronchial mucosal absorption and pulmonary retention of inhaled drugs. In an acute lung inflammation rat model, NPs with FcBP and high stiffness display superior therapeutic effects. In vitro data demonstrates that FcBP promotes bronchial mucosal absorption of NPs with high stiffness more effectively than NPs with low stiffness. The higher stiffness also enhances endocytosis and exocytosis to improve drug absorption and retention.

Summary: A simple, solvent-saving, and sensitive method using high-performance liquid chromatography coupled with high-resolution mass spectrometry was developed to quantitively determine and qualitatively identify emerging halogenated organic contaminants (HOCs) in animal-derived food samples. This method involved freezing the sample extracts to remove lipids and purifying them by thin-layer chromatography according to polarity. The method showed good detection limits, quantification limits, recoveries, precisions, and matrix effects for the 16 HOCs studied. 16 HOCs were detected in actual samples, and non-target analysis also identified bromides and chlorides in animal-derived foods.

Summary: This research proposes an innovative therapeutic approach using lipid-based magnetic nanovectors for the treatment of glioblastoma multiforme (GBM), the deadliest brain tumor. The nanovectors have dual therapeutic functions of chemotherapy and localized magnetic hyperthermia. The drug used is selected based on patient-specific screenings, and the nanovectors are modified to enhance their selectivity towards GBM cells derived from patients. The results show that hyperthermia and chemotherapy synergistically reduce cell invasion and induce cellular damage, leading to cell death.

Summary: In this study, nine common probiotic strains were tested for their ability to secrete short-chain fatty acids (SCFAs) using a sensitive and specific HPLC-MS-MS method. All tested microorganisms were shown to secrete acetic acid, with only B. clausii and S. boulardii additionally able to produce propionic and butyric acids. This experimental approach contributes to the characterization of probiotics as SCFA-producing organisms and has implications for addressing SCFA deficiency.

Summary: Spaceflight can lead to detrimental effects on living organisms, such as muscle degeneration. Recent studies have shown that nanomaterials can be used to modify cellular activities and promote specific cell phenotypes in microgravity conditions. However, the early interactions between these nanomaterials and cellular targets under altered gravity conditions have not been extensively studied. This research aims to fill this gap by examining the early interactions between cerium oxide nanoparticles (nanoceria) and human skeletal myoblasts under simulated microgravity. The results show that the nanoparticles can be internalized by the cells through various mechanisms, primarily involving macropinocytosis, and that they regulate the transcription of key antioxidant response markers, potentially providing oxidative stress alleviation and muscle protection under mechanical unloading conditions.

Summary: Ethosomes are lipid-based vesicular systems that offer unique advantages in drug delivery, especially for transdermal applications. Their high ethanol content improves flexibility and deformability, allowing them to penetrate intercellular spaces without leakage. Ethanol also increases the fluidity of dermal cell membranes, facilitating the deep penetration of nanostructures. Ethosomes can encapsulate both hydrophilic and lipophilic active agents, making them particularly useful for natural extracts with diverse chemical compositions.

Summary: We have developed a new generation of ligands (JR compounds) that target the CB2R. These compounds combine the pharmacophoric portion of CB2R positive allosteric modulator (EC21a) with that of CB2R selective orthosteric agonist (LV62). Among the tested compounds, JR22a showed dualsteric behavior as a CB2R ligand. Computational studies confirmed the binding mode of JR22a at CB2R, and its potential to prevent neuroinflammation was investigated using a human microglial cell model.

Summary: Alzheimer's disease (AD) is characterized by neuronal death, brain atrophy, and cognitive decline. Neuroinflammation, with microglia as key players, has been identified as a major cause of AD progression. Cannabinoids show potential as a preventive treatment for AD, with altered expression of endocannabinoids and their receptors reported in neurodegenerative disorders including AD. Modulation of cannabinoid receptors has been shown to have neuroprotective effects in reducing protein deposition, suggesting their therapeutic potential for neurodegenerative diseases. This review provides an overview of the involvement of cannabinoid receptors in microglia activation and highlights the role of neuroinflammation in AD pathogenesis. It also discusses recently developed candidate drugs targeting cannabinoid receptors as an innovative strategy for AD treatment and management.
