Depression is a neuropsychiatry medical condition with high prevalence, in which the hypothalamic-pituitary-adrenal axis dysfunction has been postulated as the main cause. The glucocorticoids can be harmful to the brain, particularly by induction of oxidative stress and glutamatergic damage, therefore antioxidants or neuroprotective agents could have beneficial effects. Lutein (LUT) is a dietary xanthophyll able to arrive in the brain that has been used for therapy of macular degeneration. In this sense, several studies pointed beneficial effects of LUT in the brain, particularly in the hippocampus and prefrontal cortex, key regions in mood regulation...

BACKGROUND: Standard chemotherapy is associated with low response rates and short progression-free survival among patients with pretreated metastatic triple-negative breast cancer. Sacituzumab govitecan-hziy is an antibody-drug conjugate that combines a humanized monoclonal antibody, which targets the human trophoblast cell-surface antigen 2 (Trop-2), with SN-38, which is conjugated to the antibody by a cleavable linker. Sacituzumab govitecan-hziy enables delivery of high concentrations of SN-38 to tumors...

Aberrant wound healing presents as inappropriate or insufficient tissue formation. Using a model of musculoskeletal injury, we demonstrate that loss of TGF-β activated kinase 1 (TAK1) signaling reduces inappropriate tissue formation (heterotopic ossification) through reduced cellular differentiation. Upon identifying increased proliferation with loss of TAK1 signaling, we considered a regenerative approach to address insufficient tissue production through coordinated inactivation of TAK1 to promote cellular proliferation, followed by re-activation to elicit differentiation and extracellular matrix (ECM) production...

Palmoplantar pustular psoriasis, also termed palmoplantar pustulosis (PPP), is a rare disease affecting the palmoplantar regions characterized by sterile, yellow to brown pustules mostly on erythematous skin. PPP is related to a high burden due to painful, impaired and stigmatizing character. Several isoforms of interleukin (IL) have been implicated in its pathophysiology. Here, we report on four patients with PPP treated with the novel IL-17 receptor A blocker brodalumab, in whom this therapy was not successful or showed moderate improvement combined with adverse events...

Recent studies demonstrated that a combination of the gut microbiome has the vital effect on the efficacy of anticancer immune therapies. Regulatory effects of microbiota have been shown in different types of cancer therapies such as chemotherapy and immunotherapy. Immune-checkpoint-blocked therapies are the recent efficient cancer immunotherapy strategies. The target of immune-checkpoint blocking is cytotoxic T lymphocyte protein-4 (CTLA-4) or blockade of programmed death-1 (PD-1) protein and its ligand programmed death ligand 1 (PD-L1) that they have been considered as cancer immunotherapy in recent years...

Based on morphology it is often challenging to distinguish between the many different soft tissue sarcoma subtypes. Moreover, outcome of disease is highly variable even between patients with the same disease. Machine learning on transcriptome sequencing data could be a valuable new tool to understand differences between and within entities. Here we used machine learning analysis to identify novel diagnostic and prognostic markers and therapeutic targets for soft tissue sarcomas. Gene expression data was used from the Cancer Genome Atlas, the Genotype-Tissue Expression data and the French Sarcoma Group...

Patients undergoing open-heart surgery may suffer from postoperative complications, including severe infections. Antimicrobials to treat infectious complications in this population should be selected thoughtfully, taking into account three different and fundamental issues: (i) the site of infection; (ii) the suspected or proven causative agent and its susceptibility pattern; and (iii) the risk of suboptimal pharmacokinetic characteristics and potential toxicity of the chosen drug/s. Areas covered: The present narrative review summarizes the current and future antimicrobial options for the treatment of infections developing after open-heart surgery...

BACKGROUND: Huangkui capsule (HKC), an anti-inflammatory Chinese modern patent medicine, has been now widely applied to the clinical therapy of diabetic nephropathy (DN). However, the overall therapeutic mechanisms in vivo are still unclear. Renal tubular epithelial-to-mesenchymal transition (EMT) is one of the major pathogenesis of renal interstitial fibrosis in DN. Recently, the physiological roles of NLRP3 inflammasome activation and toll-like receptor 4 (TLR4)/nuclear factor (NF)-κB signaling are closely linked to EMT...

Most cases of medulloblastoma (MB) occur in young children. While the overall survival rate can be relatively high, current treatments combining surgery, chemo- and radiotherapy are very destructive for patient development and quality of life. Moreover, aggressive forms and recurrences of MB cannot be controlled by classical therapies. Therefore, new therapeutic approaches yielding good efficacy and low toxicity for healthy tissues are required to improve patient outcome. Cancer cells sustain their proliferation by optimizing their nutrient uptake capacities...
