Chronic inflammation and lack of angiogenesis are the important pathological mechanisms in deep tissue injury (DTI). Curcumin is a well-known anti-inflammatory and antioxidant agent. However, curcumin is unstable under acidic and alkaline conditions, and can be rapidly metabolized and excreted in the bile, which shortens its bioactivity and efficacy.
This study aimed to prepare curcumin-loaded poly (lactic-co-glycolic acid) nanoparticles (CPNPs) and to elucidate the protective effects and underlying mechanisms of wound healing in DTI models.
CPNPs were evaluated for particle size, biocompatibility, in vitro drug release and their effect on in vivo wound healing.
The results of in vivo wound closure analysis revealed that CPNP treatments significantly improved wound contraction rates (p<0.01) at a faster rate than other three treatment groups. H&E staining revealed that CPNP treatments resulted in complete epithelialization and thick granulation tissue formation, whereas control groups resulted in a lack of compact epithelialization and persistence of inflammatory cells within the wound sites. Quantitative real-time PCR analysis showed that treatment with CPNPs suppressed IL-6 and TNF-α mRNA expression, and up-regulated TGF-β, VEGF-A and IL-10 mRNA expression. Western blot analysis showed up-regulated protein expression of TGF-β, VEGF-A and phosphorylatedSTAT3.
Our results showed that CPNPs enhanced wound healing in DTI models, through modulation of the JAK2/STAT3 signalling pathway and subsequent upregulation of pro-healing factors.

The present study was aimed to improve the permeability of Luliconazole (LZ) and to localize high drug concentrations at skin layers by Quality by Design (QbD) based Nanostructured lipid carriers (NC) based gel.
Quality Target Product Profile was set and Critical Quality attributes were identified. FT-IR and DSC studies confirmed compatibility. Risk assessment was carried out by screening the factors using 2
fractional factorial design and optimization by Box Behnken design. Cholesterol Cetyl Palmitate, PEG 200 and probe sonication time were identified as factors, Particle size (<200 nm), PDI (0.4), % Entrapment efficiency (% EE, >80%) and % Cumulative Drug release (% CDR, >95%) as responses. Contour plots, Overlay plots and desirability were utilized to create design space.
The quadratic polynomial equations showed that increased lipid content, PEG 200 and optimum sonication time reduced Particle size, PDI, improved % EE and % CDR. The optimized formula was formulated into a gel. Ex-vivo permeation studies performed using pig ear pinna skin revealed that developed LZ NC gel exhibited greater permeation 272.98±8.57 (µg/cm2 ) and 32.11 ±4.7 (µg/cm2 /h) flux than plain drug dispersed gel. Dermatokinetic parameters of LZ NC gel revealed that highly significant amount of LZ was permeated, distributed and transported through the skin layers. The better linear correlations were obtained by LZ permeation through synthetic membrane (in-vitro) and pig ear pinna skin (ex-vivo).
The above findings revealed that developed LZ NC gel exhibited better permeation and localization at skin layers in treating fungal infections.

This study explored the preparation and efficacy of N-QUE-NE, and the results showed that quercetin, tannin and toosendanin had satisfactory synergistic antibacterial effects. The antagonistic effect of quercetin and geniposide in nanoemulsion indicated that it is not beneficial to the antibacterial effect of Sendeng-4, and further research needs to be conducted to clarify its antibacterial effect.
Neurodegenerative diseases are often the consequence of alterations in structures and functions of the Central Nervous System [CNS] in patients. Despite obtaining massive genomic information concerning the molecular basis of these diseases and since the neurological disorders are multifactorial, causal connections between pathological pathways at molecular level and CNS disorders development have remained obscure and need to be elucidated to a great extent.
Animal models serve as accessible and valuable tools for understanding and discovering the roles of causative factors in the development of neurodegenerative disorders and finding appropriate treatments. Contrary to rodents and other small animals, large animals especially non-human primates [NHPs] are remarkably alike humans; hence, they establish suitable models for recapitulating the main human's neuropathological manifestations that may not be seen in rodent models. Also, they serve as useful models to discover effective therapeutic targets for neus of neurodegenerative disorders with high accuracy and facilitate perspectives for breakthroughs in the research on the nervous system disease therapy and drug discovery. Furthermore, the useful outcomes of CRISPR applications in various clinical phases are hopeful for their translation to the clinic in a short time.

Mycotoxins are defined as fungi that have negative effects on human health. The immune system of the organism is affected by mycotoxins first, and developmental problems, systemic diseases and death can be observed. Although this damage is important for all individuals, due to immaturity of the developmental areas, weak immune system and vulnerability against external factors, it can seriously affect children both in the pre- and in the postpartum period.
It is aimed to examine the effects of mycotoxins on child development, which is also very important in the study, together with the studies conducted.
In the research, document analysis method was used to determine the effects of mycotoxins on children. The articles examining the effects of mycotoxins and mycotoxins on children were reached from Google Scholar between 2002 and 2020, accessible books were examined and the results of these studies were discussed as a whole.
As a result of the encounter of the fetus with mycotoxins in the womb, the rate, and academic failures can be seen.Chronic kidney disease is a serious co-morbidity of patients with diabetes, which amplifies the global burden of this disease, affects the quality of their life and significantly increases both morbidity and mortality. Therefore, there is high unmet clinical need to develop therapeutic strategies in order to prevent, delay or even reverse its evolution. EMPA-REG OUTCOME trial has fundamentally changed the therapeutic landscape of patients with type 2 diabetes and signified a new era, in which treatment approaches should be tailored based on end-organ protection and patient comorbidities rather than focusing only on their antihyperglycemic effects. This paper discusses the seminal EMPA-REG OUTCOME trial, focusing on its renal outcomes, and explores extensively the possible pathophysiological mechanisms governing the nephroprotective activity of empagliflozin both in in vitro and in vivo (animal models and humans) studies during a diabetic state. It also discusses the safety of empagliflozin therapy and its future role in order to ameliorate the global burden of CKD both in patients with and without diabetes.Threats, challenging events, adverse experiences, predictable or unpredictable, namely stressors, characterize life, being unavoidable for humans. The hypothalamus-pituitary-adrenal axis (HPA) and the sympathetic nervous system (SNS) are well-known to underlie the physiology of adaptation to psychosocial stress, in the context of a variety of other interacting systems, signals and mediators. However, considerable effort is still required to fully elucidate such modulatory cues in order to understand how and why the 'brain-body axis' acts for resilience or, on the contrary, cannot cope with stress, under a biochemical and biological point of view. Indeed, failure to adapt increases both the risk of developing and/or relapsing into mental illnesses such as burnout, post-traumatic stress disorder (PTSD) and at least some types of depression, even favoring/worsening the onset of neurodegenerative and somatic co-morbidities, especially in the elderly. We will review here current knowledge on this area, focusing on works presenting the main brain centers responsible of stressor interpretation and processing, as well as on those highlighting the physiology/biochemistry of the ensuing endogenous responses, trying to evidence the most promising lines of future research. Autonomic and HPA patterns, inflammatory cascades and energy/redox metabolic arrays will be presented, on the one hand, as promoters of allostasis, leading towards adaptation to psychosocial stress and homeostasis, on the other as possible vulnerability factors for allostatic overload and non-adaptive reactions. The existence of allostasis buffering systems will be also underscored. Finally, we will prospect that the combined uses of cell cultures, animal models and wide-omics investigations may constitute a powerful tool to entangle the biochemical signature of resilience or stress-related illness, a much helpful facet for improving patients' treatment and monitoring.
