Anti-Inflammatory Effect of Geniposide on Osteoarthritis by Suppressing the Activation of p38 MAPK Signaling Pathway.
In this study, we evaluated the inhibition effect of geniposide on the inflammatory progression of the surgically induced osteoarthritis and whether the protective effect of geniposide on OA is related to the inhibition of the p38 MAPK signaling pathway. In vitro, geniposide attenuated the expression of inflammatory cytokines including interleukin-1 (IL-1), tumor necrosis factor (TNF-α), and nitric oxide (NO) production as well as matrix metalloproteinase- (MMP-) 13 in chondrocytes isolated from surgically induced rabbit osteoarthritis model. Additionally, geniposide markedly suppressed the expression of IL-1, TNF-&a...

Toxic Effects of Di-2-ethylhexyl Phthalate: An Overview.
Abstract Di-2-ethylhexyl phthalate (DEHP) is extensively used as a plasticizer in many products, especially medical devices, furniture materials, cosmetics, and personal care products. DEHP is noncovalently bound to plastics, and therefore, it will leach out of these products after repeated use, heating, and/or cleaning of the products. Due to the overuse of DEHP in many products, it enters and pollutes the environment through release from industrial settings and plastic waste disposal sites. DEHP can enter the body through inhalation, ingestion, and dermal contact on a daily basis, which has raised some concerns ...

Sarcoid-like reactions in patients receiving modern melanoma treatment
The development of cancer immunotherapy and targeted therapy has reached an important inflection point in the history of melanoma. Immune checkpoint inhibitors and kinase inhibitors are today’s standard of care treatments in advanced melanoma patients. Treatment-related toxicities can be very intriguing and quite challenging. Sarcoidosis is a multisystemic granulomatous disease characterized by an aberrant immune response to unknown antigens, whereas sarcoid-like reactions (SLRs) refer to localized clinical features. We carried out a single-center observational study in patients with stage IIB–IV melanoma treat...

Combination immunotherapies implementing adoptive T-cell transfer for advanced-stage melanoma
Immunotherapy is a promising method of treatment for a number of cancers. Many of the curative results have been seen specifically in advanced-stage melanoma. Despite this, single-agent therapies are only successful in a small percentage of patients, and relapse is very common. As chemotherapy is becoming a thing of the past for treatment of melanoma, the combination of cellular therapies with immunotherapies appears to be on the rise in in-vivo models and in clinical trials. These forms of therapies include tumor-infiltrating lymphocytes, T-cell receptor, or chimeric antigen receptor-modified T cells, cytokines [interleuk...

Vulvar Recurrences After Intensity-modulated Radiation Therapy for Squamous Cell Carcinoma of the Anus
Conclusions: In a cohort of patients treated with IMRT-based chemoradiation, 2 vulvar recurrences were identified within the avoided external genitalia despite limited recurrence rates within the cohort overall. This experience suggests that for patients with a locally advanced primary tumor and bulky bilateral inguinal or pelvic disease, the in-transit vulvar dermal lymphatics may be at risk for subclinical involvement and subsequent recurrence. If substantiated by a similar pattern of recurrence at other institutions, the external genitalia may need to be reclassified from an avoidance structure to a clinical treatment...

Lead hazard evaluation for cathode ray tube monitors in Brazil
Abstract Cathode ray tube (CRT) monitors are electronic equipment mainly made of glass, polymers and metals. These devices became obsolete because of emerging technologies such as LCD, LED and plasma; thus generating a huge stockpile of e-waste worldwide. In this CRT study, a natural leaching simulation (NBR10005) was performed to determine the toxicity of this e-waste. The standard NBR 10005 procedure was performed for 7 different monitors. The results show all samples are hazardous according to local environmental law (NBR 10004) due to lead leaching. The CRT panel is lead free, while the CRT funnel and neck have about 2...

[Variability of chloroquine and hydroxychloroquine retinopathy among various ethnicities].
CONCLUSION: The pathophysiology of these ethnic differences is unknown and may be due to distinct genetic predisposition to CQ and HCQ toxicity. Screening strategies should be adjusted to the ethnicity and performed in Asian subjects with larger visual fields (30°C), along with SD-OCT, looking for ellipsoid disruption≥8°C from the fovea. The recognition of this pericentral topography and an adjusted screening protocol should avoid late diagnosis in Asians treated with CQ and HCQ.

Antibiotics with Interleukin-15 Inhibition Reduce Joint Inflammation and Bone Erosions but Not Cartilage Destruction in Staphylococcus aureus-Induced Arthritis [Bacterial Infections]
Staphylococcus aureus-induced arthritis causes rapid joint destruction, often leading to disabling joint damage despite antibiotics. We have previously shown that interleukin-15 (IL-15) inhibition without antibiotics is beneficial in S. aureus-induced arthritis. We therefore hypothesized that the inhibition of IL-15, in combination with antibiotics, might represent a useful therapy that would reduce inflammation and joint destruction but preserve the host's ability to clear the infection. Female wild-type C57BL/6 mice were intravenously inoculated with the toxic shock syndrome toxin 1 (TSST-1)-producing LS-1 strain of S. a...

FXR Deletion in Hepatocytes does not Affect the Severity of Alcoholic Liver Disease in Mice
Emerging evidence has shown that FXR activation ameliorates the development of alcoholic liver diseases (ALD) while whole-body deficiency of FXR in mice leads to more severe ALD. However, it ’s unknown whether the enhanced susceptibility to ALD development in FXR−/− mice is due to deficiency of hepatic FXR or increased toxicity secondary to increased bile acid (BA) levels. Hepatocyte-specific FXR knockout mice (FXRhep−/−) present similar BA levels compared to wild-type mice, a nd are therefore a useful model to study a direct role of hepatic FXR in ALD development.

Multigenerational Effects of Maternal Cigarette Smoke Exposure during Pregnancy on Sperm Counts of F1 and F2 Male Offspring
This study used a mouse model to investigate the effects of maternal exposure to cigarette smoke on reproductive systems in F1 and F2 male offspring. Female ICR mice were exposed either to clean air or to cigarette smoke during pregnancy at the post-implantation stage. Epididymal sperm counts were decreased in a cigarette smoke dose–dependent manner in F1 (by 40–60%) and F2 males (by 23–40%) at postnatal day 56. In F1, the seminiferous epithelium heights were lower in the cigarette smoke–exposed groups than in the control group, and these effects were sustained in F2 males. Results suggest that mate...

Evaluation of relative dose intensity during the early phase of first-line sunitinib treatment using a 2-week-on/1-week-off regimen for metastatic renal cell carcinoma
AbstractSunitinib treatment with a 2-week-on/1-week-off schedule (Schedule 2/1) is a common alternative regimen with high relative dose intensity (RDI) and superior tolerability for patients with metastatic renal cell carcinoma (mRCC). The prognostic impact of RDI is reported only in 4-week-on/2-week-off or mixed regimens. Herein, we evaluated the prognostic impact of RDI during early-phase sunitinib treatment using Schedule 2/1. Seventy-four patients who received first-line sunitinib treatment using Schedule 2/1 were evaluated. Endpoints were progression-free survival (PFS) and overall survival (OS). We assessed RDI withi...

Protective Effect of Apigenin on Acrylonitrile-Induced Inflammation and Apoptosis in Testicular Cells via the NF- κB Pathway in Rats
AbstractApigenin (AP) as a plant flavonoid is found to attenuate acrylonitrile (ACN) toxicity by reducing ROS production and inhibiting apoptosis. Therefore, the present study aimed to evaluate the role of AP on ACN-induced inflammation and apoptosis in germ cells and whether it is through the NF- κB signaling pathway. AP increased the concentrations of lactate dehydrogenase isozyme (LDH) and sorbitol dehydrogenase (SDH), while the concentrations of interleukin β (IL-1β), tumor-necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were significantly reduced.
