The study was endeavored to investigate the effects of soil properties on the acute and chronic cadmium (Cd) toxicities to Folsomia candida (Collembola F. candida). Results of the present study indicated that 10% lethal concentrations (LC10) in a period of 7 days were ranged from 68.6 to > 1000 mg/kg Cd. Soil Cd concentrations that halve F. candida reproductions (EC50, 28 days) were ranged from 41.4 to 146.8 mg/kg. Stepwise regression analysis between the thresholds of Cd toxicity and soil properties revealed that the pH and organic matter (OM) were two fundamental factors for the assessment of biological threats posed by Cd...

Chicken-based ingredients are commonly used in pet food products, but vary greatly in nutrient composition and processing conditions that may affect their protein quality and digestibility. Testing the quality of protein sources undergoing different processing conditions provides important information to pet food producers. The objective of this study was to determine the chemical composition, nutrient digestibility, protein, and amino acid (AA) digestibility scores, and nitrogen-corrected true metabolizable energy (TMEn) of chicken-based ingredients that had undergone different processing conditions (i...

Photobiomodulation (PBM) is emerging as an effective strategy for the management of multiple inflammatory conditions, including oral mucositis (OM) in cancer patients who receive chemotherapy or radiotherapy. Still, the poor understanding of the mechanisms by which the light interacts with biological tissues and the heterogeneity of light sources and protocols employed worldwide significantly limits its applicability. Reactive oxygen species (ROS) are massively generated during the early phases of OM and play a major role in the pathogenesis of inflammation in general...

Visceral obesity is associated with insulin resistance and higher risk of type 2 diabetes and metabolic diseases. A limited ability of adipose tissues to remodel through the recruitment and differentiation of adipose stem cells (ASCs) is associated with adipose tissue inflammation and fibrosis and the metabolic syndrome. We show that the lower adipogenesis of omental (Om) compared to abdominal subcutaneous (Abdsc) ASCs was associated with higher secretion of TGFβ ligands that acted in an autocrine/paracrine loop to activate SMAD2 and suppress adipogenesis...

BACKGROUND: Patients with organ confined muscle-invasive bladder cancer (MIBC) who are candidates for radical cystectomy (RC) should receive neoadjuvant chemotherapy (CHT). However, the most contemporary CHT use rates indicate low adherence to these guidelines. We tested contemporary neoadjuvant CHT rates and associated cancer-specific mortality (CSM) and overall mortality (OM) in pT2N0 MIBC patients treated with RC. MATERIALS AND METHODS: Within the SEER database (2004-2015), we identified patients with pT2N0 MIBC patients who underwent RC...

The aim of this work was to compare the impact of different adding forms of dicyandiamide (DCD) on NH3 and greenhouse gas (GHG) emissions during sewage sludge (SS) composting. Four treatments were set up using SS mixed with sawdust, to which DCD was then added by mixing (M), surface broadcasting (B), and a combination of the two (M+B). The treatment without DCD applied was used as the control. The results indicate that the addition of DCD slightly inhibited the organic matter (OM) degradation, but that it had no significant effect on CO2 emission...

Background: The transformation of nonosseous soft tissue into bone is known as osseous metaplasia (OM). This condition most commonly affects the musculoskeletal and central nervous systems and it is a well-known phenomenon in different soft tissue organs. Rarely, OM can affect the uterus, which can extend into the cervix. OM affecting the cervix alone is a more rare condition that has multiple different clinical presentations. The presentation can be similar to that of a tumor in extremely rare cases...

The amination of various phosphorodiamidate-substituted pyridines, quinolines, and quinoxaline with magnesium amides R2 NMgCl·LiCl proceeds at room temperature within 8 h. Several pharmaceutically active amines were suitable substrates for this amination procedure, and also the antihistaminic tripelennamine was prepared. Additionally, several heterocyclic phosphorodiamidates underwent directed ortho-metalation (D oM) using TMPMgCl·LiCl (TMP = 2,2,6,6-tetramethylpiperidyl) or TMP2 Mg·2LiCl, followed by electrophilic functionalization prior to the amination step, which led to ortho-functionalized aminated N-heterocycles...
