This study explored injection drug users' (IDUs) perceptions of drug abuse treatment and treatment providers in three Russian cities as well as their attitudes toward opiate substitution therapy, which is currently not available in Russia. Data were collected from 121 qualitative interviews with IDUs conducted in 2003-2004. Negative perceptions of available treatments were related to poor treatment outcomes, judgmental service providers, lack of psychologic services, and short lengths of stay in treatment. Positive perceptions were associated with receiving psychosocial care and nonjudgmental attitudes from providers. Most participants had heard about opiate substitution therapy, and some had treated themselves using methadone from the black market. Although respondents had doubts that opiate substitution therapy could work effectively in Russia, most agreed that this type of treatment would help IDUs function better in the society.

Background: The healthcare sector faces a growing threat from the rise of highly resistant microorganisms, particularly Methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Pseudomonas aeruginosa (MDR P. aeruginosa). Facing the challenge of antibiotic resistance, nanoparticles have surfaced as promising substitutes for antimicrobial therapy.

Syndromic ichthyoses are a group of disorders whose genetic alterations impact both epidermal and non-epidermal tissues. Therefore, patients present symptoms in other organs. Most are extraordinary and, in some, ichthyosiform desquamation has been poorly described.

Prolonged exposure to interferon-gamma (IFNγ) and the associated increased expression of the enzyme indoleamine 2,3-dioxygenase 1 (IDO1) create an intracellular shortage of tryptophan in the cancer cells, which stimulates ribosomal frameshifting and tryptophan to phenylalanine (W>F) codon reassignments during protein synthesis. Here, we investigated whether such neoepitopes can be useful targets of adoptive T cell therapy. Immunopeptidomic analyses uncovered hundreds of W>F neoepitopes mainly presented by the HLA-A24:02 allele.

Osteoporosis, characterized by reduced bone mineral density and increased fracture risk, poses a significant health challenge, particularly for aging populations. Systemic treatments often lead to adverse side effects, emphasizing the need for localized solutions. This study introduces a 3D-printed polycaprolactone (PCL) scaffold embedded with strontium-substituted mesoporous bioactive glass nanoparticles (Sr-MBGNPs) and icariin (ICN) for the targeted regeneration of osteoporotic bone.

In cases of large mandibular continuity defects resulting from malignancy resection, the current standard of care involves using patient-specific/custom titanium reconstruction plates along with autogenous grafts (fibula, scapula, or iliac crest segments). However, when grafts are not feasible or desired, only the reconstruction plate is used to bridge the gap. Unfortunately, metal osteosynthesis and reconstruction plates, including titanium, exhibit adverse effects such as stress-shielding and limitations in accurate postoperative irradiation (especially with proton-beam therapy).
