Abstract
Injectable biostimulatory agents such as poly-L-lactic acid (PLLA), polycaprolactone (PCL), and calcium hydroxyapatite (CaHA) have emerged as key tools in regenerative aesthetics due to their ability to stimulate adipogenesis and adipocyte metabolic activity, enhance collagen production, and improve dermal quality.

Injectable biostimulatory agents such as poly-L-lactic acid (PLLA), polycaprolactone (PCL), and calcium hydroxyapatite (CaHA) have emerged as key tools in regenerative aesthetics due to their ability to stimulate adipogenesis and adipocyte metabolic activity, enhance collagen production, and improve dermal quality. This review aimed to provide an updated synthesis of the role of these agents in adipocyte stimulation, focusing on their mechanisms of action, clinical efficacy, and therapeutic applications. A comprehensive search of the MEDLINE, PubMed, and Ovid databases was conducted for studies published from 2018 onward, including in vitro and in vivo experiments, randomized controlled trials, and observational studies, which were evaluated according to the Oxford Centre for Evidence-Based Medicine hierarchy. The findings demonstrated that PCL promotes adipose-derived stem cell differentiation and extracellular matrix remodeling, while PLLA exhibits dual effects on collagen synthesis and adipocyte stimulation, with clinical trials such as the SPLASH study confirming significant improvements in dermal thickness and adipogenesis. CaHA provided immediate volumizing benefits with long-term tissue regeneration, and innovative approaches including combination therapies and novel injection protocols expanded clinical applications. Overall, PLLA, PCL, and CaHA represent effective and versatile biostimulatory agents that support natural and durable outcomes in aesthetic practice. Nevertheless, the absence of large-scale trials and standardized protocols highlights the need for further research to optimize safety, efficacy, and long-term treatment strategies. Full article

Over the last decade, additive manufacturing (AM) has been widely investigated for developing on-demand, patient-centric, and personalized medications. Among various AM techniques, fused deposition modeling (FDM), semi-solid extrusion (SSE), inkjet printing, binder jet printing, stereolithography (SLA), and selective laser sintering (SLS) have been most widely studied for developing simple and complex pharmaceutical medications. Implementing the AM platform enables decentralized manufacturing of medications at the hospitals and clinical sites. The dose and release profiles of the dosage forms can be tailored based on patient needs, providing flexibility to the physician. In fact, streamlining the AM process into a continuous manufacturing process equipped with process analytical technology (PAT) tools will ensure the manufacturing and delivery of safe and efficacious medications to the patient population. Complex medications, such as polypills, which are complex and time-consuming to manufacture using traditional manufacturing techniques, can be printed quickly using the AM approach. The pediatric patient population can be attracted to medication by printing the dosage forms with a geometry of interest. The AM platform can be integrated with artificial intelligence (AI) and health records to accelerate drug development and tailor medications based on patient conditions. Despite the various advantages that the AM platform brings to the pharmaceutical field, a few limitations, such as scalability, material innovation, secondary processing, and regulatory evolution, need to be addressed. This review article compares the advantages and limitations of the existing AM techniques along with a note on the recent advancements and future perspectives. Full article

In this study, a terminological and grammatical survey of essential and fatty oils of plant origin was performed in the selected Austrian, Hungarian, Spanish, and Belgian pharmacopoeias from the 18th to 19th centuries. The Latin-language prescriptions were analysed for their content, sections, and indications, and then translated from Latin into English, and supplemented with the source plants. Oil types were categorised based on their preparation and origin. Most oils belong to essential oils in Ph. Austriaca I–IV, Ph. Belgica, and Ph. Hungarica I (20 in each). Cooked oils are described as having the highest number in Ph. Hispanica (21), while pressed oils are also included in a high ratio in Ph. Hisp. (18) and Ph. Austriaca V (15). At the same time, those from minerals are described only in Ph. Belg. (2) and Ph. Hisp. (5). Latin terms are used in preparation methods, including the most concise descriptions in Ph. Austriaca V and Ph. Hg. I. This comprehensive study provides new linguistic data on the oils of herbs in the selected pharmacopoeias. Studies of essential oils have recently been progressing, and this analysis might help in understanding information from old pharmacopoeias. Full article

Biopharmaceuticals are medical drugs produced by means of biotechnology. In contrast with small-molecule (traditional) drugs, which are usually synthesized chemically, biopharmaceuticals are derived from biological sources, including tissues, cells, or microorganisms. Biopharmaceuticals comprise a wide extent of therapies, such as vaccines, monoclonal antibodies, cell therapies, recombinant proteins, and gene therapies, as well as biosimilars. These products are designed to become important treatment options for different diseases, including cancer, autoimmune pathological disorders, andinfectious diseases. The development of biopharmaceuticals often includes multifaceted processes, involving genetic engineering and cellular culture techniques, to guarantee efficacy and safety. Accordingly, biopharmaceuticals’ legislation is a key component for ensuring the highest quality of medical products, as well as protecting public health. As a rapidly developing area inside the pharmaceutical industry, biopharmaceuticals represent a significant advancing stage in modern medicine, offering targeted therapies that can improve patient outcomes. Accordingly, this paper seeks to provide current state-of-the-art didactic information, including better insight into various challenges related to biopharmaceuticals’ development, classification, medical use, legislation and ethics.

Docetaxel (DTX)-loaded polymeric nanoparticles composed of Eudragit RL and RS 100 were developed by solvent evaporation using D-α-tocopheryl polyethene glycol 1000 succinate as an emulsifier and optimised by Central Composite Design. The effects of homogenisation and sonication times on entrapment efficiency (%EE) and drug release (%DR) were statistically analysed across nine batches. Particle size (PS) ranged from 302 ± 1.0 to 502 ± 2.0 nm, and zeta potential (ZP) from 25.8 ± 2.5 to 42.9 ± 1.7 mV. %EE and %DR (pH 1.2 for 2 h, then pH 7.4 for 22 h, 40 mL medium at 37 ± 0.5 °C) ranged from 69.32 ± 3.77 to 92.71 ± 0.16% and 19.24 ± 3.03 to 49.17 ± 1.98%, respectively. Optimised DTX nanoparticles (DNPs) showed EE of 78.18 ± 0.56%, DR of 46.21 ± 1.41% at 24 h, PS of 357.9 ± 2.4 nm, and ZP of 42.9 ± 3.7 mV. Scanning electron microscopy revealed ~300 nm cuboidal particles with smooth surfaces. X-Ray Diffraction and Differential Scanning Colorimetry confirmed reduced drug crystallinity in DNPs. In vitro haemolysis assays showed ~11.5-fold lower haemolytic potential (p < 0.0001) versus DTX, confirming improved safety. Fluorescence microscopy indicated enhanced cellular uptake of DNPs in MDA-MB-231 cells, while cytotoxicity assays of DNPs showed a lower IC50 (39.52 µM) compared to DTX (60.81 µM), demonstrating superior anticancer efficacy. Overall, DNPs represent a promising oral chemotherapy platform for breast cancer management. Full article

Benign prostatic hyperplasia (BPH) and prostatitis are multifactorial urological disorders associated with chronic inflammation, oxidative stress, and androgenic imbalance. Dysphania ambrosioides (L.) Mosyakin & Clemants contains flavonoids and phenolic acids with well-recognised antioxidant and anti-inflammatory properties; however, its potential activity against the molecular targets of these prostatic disorders has not been systematically evaluated. A comparative quantitative analysis was performed using studies published between 2005 and 2025 that reported antioxidant activity (DPPH assay, IC50 in µg/mL) of D. ambrosioides extracts. Metabolites from extracts with IC50 values below the global mean (398.410 ± 81.810 µg/mL; n = 35) were selected for in silico prioritisation using OSIRIS, PASS, and ProTox 3.0, followed by molecular docking (CB-Dock2) against AR, 5AR2, COX-2, NLRP3, and α1A receptors. Luteolin and rosmarinic acid showed favourable binding energies (−9.5 to −7.7 kcal/mol) comparable in magnitude to reference drugs (finasteride −13.4, celecoxib −11.4, tamsulosin −7.3 kcal/mol). These metabolites, exhibited affinity for androgenic, inflammatory, and adrenergic targets, suggesting their potential to modulate key mechanisms underlying both BPH and prostatitis. This study integrates, for the first time, a quantitative assessment of antioxidant activity with a multitarget in silico analysis of D. ambrosioides, prioritising luteolin and rosmarinic acid as natural candidates with potential antioxidant, anti-inflammatory, and antiandrogenic properties relevant to prostatic health.

Bioactive ingredients are compounds, typically derived from natural sources, that provide specific health benefits or perform certain beneficial functions. Although they can play a role in maintaining good health, their effects can vary widely based on a person’s specific genotype and phenotype, leading to situations where certain ingredients induce beneficial responses for some individuals but not others. Herein, we report a method for the rapid discovery of relationships between genes, bioactive ingredients, and physiological effects. First, RNA-Seq was performed after applying 6 plant-derived ingredients to a three-dimensional skin model. After determining expression changes for each ingredient, these changes were ranked and visualized using score-based prediction models. Based on our analysis, we were able to quickly determine and visualize the effect (or lack thereof) of the ingredients on gene expression. Our findings demonstrate the utility of combining RNA-Seq with score-based models and visualizations for screening bioactive ingredients by gene expression, visualizing their impact based on ingredient or physiological effect, and the applicability of this method to any bioactive ingredient for rapid determination of potential ingredients relevant to maintaining health and wellness.

Diabetes mellitus (DM) is a disease that affects over 537 million people worldwide and results in 6.7 million deaths annually. Conventional treatment of this disease focuses on lifestyle changes and drug administration. However, very few people can adhere to a healthier lifestyle, and drugs are difficult to access, especially in low- and middle-income countries. An alternative as an adjuvant to the treatment of DM is the phenolic compounds from plants with reported anti-diabetic effects. However, the bioavailability of these compounds is very low since they are affected by the gastrointestinal tract and xenobiotic metabolism. To improve the availability of these compounds, an emerging technology such as encapsulation is being used since it has been reported that the encapsulation of phenolic compounds improves both their bioaccessibility and bioavailability, as well as their bioactivity. In this review, we will focus on compiling the most up-to-date information on the different encapsulation processes of phenolic compounds and the antidiabetic effect of encapsulated phenolic compounds using the databases PubMed, Scopus, Web of Science, and Google Scholar. We will discuss the mechanisms, pathways, and receptors involved in the modulation of DM, especially those related to inflammation, oxidative stress, and insulin resistance. Full article

Radiotherapy (RT) is a standard treatment for cervical cancer, but its efficacy is often limited by tumor hypoxia and low radiosensitivity. Radiosensitizers that enhance RT without dose escalation are therefore of clinical interest. Alpha-mangostin (AM), a xanthone from Garcinia mangostana, exhibits anticancer and ROS-inducing properties. This study evaluated whether AM enhances radiosensitivity in vitro. Cytotoxicity (0–35 µM) was assessed by the MTT assay, and radiation sensitivity (0–6 Gy) was assessed by clonogenic survival. γ-H2AX immunofluorescence, cell cycle distribution, apoptosis induction, and clonogenic survival assessments were used to investigate the radiosensitization effect. AM showed dose-dependent cytotoxicity in HeLa cells at an inhibitory concentration 20 (IC20) of 13.67 µM while sparing fibroblasts. The radiation lethal dose 20 (LD20) was 1.4 Gy. However, combination treatment used AM at 12 µM (IC14) combined with 2 Gy (LD30) irradiation to avoid 50% cell death. AM enhanced G2/M arrest by 21.10% (p < 0.01) versus controls. In combination treatment, AM significantly increased γ-H2AX-positive cells to 48.2% (p < 0.0001), elevated apoptosis to 39.48% (p < 0.0001), and decreased clonogenic survival to 28% (p < 0.0001) compared with control. A combination index of about 0.9 indicated synergism. Therefore, AM effectively radiosensitized HeLa cells via increased DNA double-strand breaks and G2/M arrest. Full article

The γδ T cells belong to a subgroup of T cells known as non-conventional T cells due to their limited T cell receptor (TCR) repertoire and ability to recognize non-peptide antigens. They play a crucial role in combating infections and tumors. Vγ9Vδ2 T cells are typically activated by molecules containing diphosphate groups, collectively known as phosphoantigens (pAgs), through a non-canonical mechanism which involves the intracellular domain of butyrofilin (BTN)3A1 protein. However, no FDA-approved drugs have yet been shown to activate them, and the underlying cellular mechanisms remain unknown. In this study, we combined high-throughput virtual screening of an FDA-approved drug database with in vitro cellular assays to identify potential γδ T cells activators. Our findings demonstrate that Nitazoxanide (NTZ) and Tinidazole induce moderate elicited a statistically significant increase in interferon (IFN)-γ production of Vγ9Vδ2 T cells by their probably interaction with the pAg binding site of BTN3A1. Additionally, NTZ induces expression of CD107a, but only at the highest concentrations tested and promotes the upregulation of HLA-DR in total PBMCs and CD14+ monocytes. Blocking BTN3A with a specific antibody led to a marked reduction in all NTZ-induced activations. This work identifies NTZ as a previously unrecognized activator of γδ T cells, highlighting its immunomodulatory potential beyond its known clinical uses. These findings broaden our understanding of γδ T cells pharmacology and suggest new opportunities for drug repurposing and the design of novel chemical scaffolds. Further mechanistic studies will be essential to fully define how NTZ engages the BTN3A–γδ T cells axis. Full article

As a metabolism-controlling peptide, insulin affects activity of almost all tissues in human organisms, including the ones located in the central nervous system. By modifying glucose uptake and processing, as well as inducing anabolic effects, insulin alters functions of various nerve centers. Data from numerous clinical trials prove that such actions can have positive influence on cognitive processes or might be utilized as measures to control appetite, mood, and blood flow, or to prevent unfavorable mental states associated with diminished ability to maintain homeostasis. The intranasal route of administration provides an efficient and targeted delivery method, allowing insulin to be applied directly to different brain regions via the nasal mucosa. Such an approach can also reduce the risk of potential adverse effects associated with this medication, including drops in plasma glucose levels. This review gathers clinical studies’ findings on intranasal insulin’s neuromodulatory properties and its efficacy as additional treatment measure in several neuropsychiatric disease entities.

Monkeypox (Mpox) has re-emerged as a global public health threat, with recent outbreaks linked to novel mutations that enhance viral transmissibility and immune evasion. The Mpox virus (MPXV), a double-stranded deoxyribonucleic acid (DNA) orthopoxvirus, shares high structural and enzymatic similarity with the variola virus, underscoring the need for urgent therapeutic interventions. While conventional antiviral development is time-intensive and costly, drug repurposing offers a rapid and cost-effective strategy by leveraging the established safety and pharmacological profiles of existing medications. This is a narrative integrative review synthesizing published evidence on drug repurposing strategies against MPXV. To address these issues, this review explores MPXV molecular targets critical for genome replication, transcription, and viral assembly, highlighting how the Food and Drug Administration (FDA)-approved antivirals (cidofovir, tecovirimat), antibiotics (minocycline, nitroxoline), antimalarials (atovaquone, mefloquine), immunomodulators (infliximab, adalimumab), and chemotherapeutics (doxorubicin) have demonstrated inhibitory activity against the virus using computational or experimental approaches. This review further evaluates advances in computational methodologies that have accelerated the identification of host-directed and viral-directed therapeutic candidates. Nonetheless, translational challenges persist, including pharmacokinetic limitations, toxicity concerns, and the limited efficacy of current antivirals such as tecovirimat in severe Mpox cases. Future research should integrate computational predictions with high-throughput screening, organ-on-chip technologies, and clinical pipelines, while using real-time genomic surveillance to track viral evolution. These strategies establish a scalable and sustainable framework for the MPXV drug discovery. Full article

Pharmaceutical care in European countries is at various stages of development. Although the problem of occupational burnout affects many professions, it is particularly relevant among healthcare workers, such as pharmacists. Studies assessing pharmacists’ life satisfaction and factors influencing the level of occupational burnout play an important role in social pharmacy. Therefore, the present study aimed to evaluate the impact of providing pharmaceutical care on the professional life satisfaction of pharmacists in Poland. This study was conducted as an anonymous online survey. It included pharmacists who are members of the professional self-government in Poland. A custom-designed questionnaire was used for data collection, and 91 completed questionnaires were obtained. The respondents were divided into four groups according to their professional experience: up to 5 years, 6–10 years, 11–20 years, and over 20 years. In response to questions regarding job satisfaction and the willingness to provide pharmaceutical care, the respondents gave affirmative answers. Pharmacists in Poland have a positive perception of the impact of pharmaceutical care on the prestige of their profession. Currently, the pharmaceutical care services most commonly provided are those financed by the State; however, pharmacists are willing to engage in such activities and expect an expansion of the scope of reimbursed services. Consequently, pharmacists express dissatisfaction with the current stage of pharmaceutical care implementation in Poland. Those who provide pharmaceutical care feel more appreciated in their profession, do not experience psychological strain, do not feel uncomfortable when communicating with patients, and are not afraid of the responsibility associated with providing such services. Nevertheless, they consider it an additional workload in their professional duties. Full article

Changes in membrane lipid composition constitute a key bacterial resistance mechanism. In Staphylococcus aureus, phosphatidylglycerol undergoes lysine modification to form lysyl-phosphatidylglycerol, a cationic lipid that reduces the net negative surface charge and thereby enhances resistance to cationic antimicrobial peptides. In this study, we examined the influence of lysyl-PG on the membrane activity of three antimicrobial peptides with distinct physicochemical characteristics: LL-37, F5W Magainin II, and NA-CATH:ATRA-1-ATRA-1. Model membranes composed of phosphatidylglycerol and cardiolipin were supplemented with increasing molar fractions of lysyl-phosphatidylglycerol, and peptide–membrane interactions were characterized using Fourier-transform infrared spectroscopy. Membrane fluidity was evaluated through shifts in the symmetric methylene stretching bands, while changes in interfacial polarity were assessed via the carbonyl and phosphate asymmetric stretching bands. LL-37 induced pronounced disruption of anionic bilayers, an effect progressively attenuated by lysyl-phosphatidylglycerol, particularly within the hydrophobic core. F5W Magainin perturbed both hydrophobic and interfacial regions across a broader range of lysyl-phosphatidylglycerol concentrations, whereas NA-CATH:ATRA-1-ATRA-1 primarily targeted interfacial domains, with minimal disruption of acyl chain order. Increasing lysyl-PG content modulated the extent of bilayer disorder and dehydration at the hydrophobic–hydrophilic interface, with each peptide exhibiting a distinct interaction profile. Collectively, these findings provide mechanistic insights into lysyl-PG-mediated modulation of peptide activity and highlight the role of lipid remodeling as a bacterial defense strategy.

Adenosine, a purine nucleoside involved in neuromodulation and smooth muscle relaxation, was recently identified in C. pepo seeds. Since A1 adenosine receptors (A1AR) suppress parasympathetic bladder overactivity by inhibiting acetylcholine (ACh) release, we investigated to which extent purines from pumpkin seed extracts contribute to A1AR activation. Complementary antioxidant capacity was assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Three hydrophilic seed extracts containing different adenosine levels (0.60–1.18 mg/g dw) were evaluated for agonist activity using a cAMP inhibition assay. The most active extract showed an EC50 of 40.22 µg/mL. Selective removal of adenosine shifted the dose–response curve rightward, while further elimination of an adenosine derivative increased the EC50 to 212.10 µg/mL, confirming adenosine as the principal active compound. Guanosine and inosine did not exhibit A1AR agonist or allosteric effects. All samples exhibited measurable but weak antioxidant activity (IC50 = 1.02–4.19 mg/mL), consistent with their low total phenolic content. These findings underscore the importance of accounting for naturally occurring agonists in plant extracts to avoid overestimating receptor-mediated effects in vitro which are not translatable in vivo.

Abstract
This review explores the pharmacological potential of chondroitin sulfate and fucoidan as immunomodulatory agents targeting N-acetylgalactosaminidase (nagalase) to normalize immune responses. Nagalase, an enzyme produced by tumor and virus-infected cells, contributes to immune suppression by deactivating macrophage-activating factor. Both chondroitin sulfate and fucoidan, [...] Read more.
This review explores the pharmacological potential of chondroitin sulfate and fucoidan as immunomodulatory agents targeting N-acetylgalactosaminidase (nagalase) to normalize immune responses. Nagalase, an enzyme produced by tumor and virus-infected cells, contributes to immune suppression by deactivating macrophage-activating factor. Both chondroitin sulfate and fucoidan, as representatives of glycosaminoglycans and heteropolysaccharides, exhibit significant potential in inhibiting nagalase activity, thereby restoring immune functionality. Chondroitin sulfate, a key component of the extracellular matrix, demonstrates anti-inflammatory and tissue-regenerative properties by modulating nuclear factor (NF)-κB pathways and cytokine expression. Fucoidan, a sulfated polysaccharide derived from brown seaweed, enhances immune responses through macrophage and natural killer cell activation, while also exhibiting antiviral and anticancer activities. This dual action positions these compounds as promising agents for therapeutic interventions in chronic inflammatory conditions, cancer, and infectious diseases. The synergistic effects of chondroitin sulfate and fucoidan highlight their potential to address the root causes of immune dysregulation. This review aims to elucidate the underlying mechanisms of action and explore the clinical applications of these compounds within the framework of innovative immunotherapeutic strategies. However, current evidence is limited by the predominance of preclinical studies and variability in experimental models. Well-designed clinical trials are needed to validate their efficacy for therapeutic use. Full article
