Some of the DBPs identified in the controlled experiments were also detected in the pool water samples. The toxicity of the 9 DBPs identified was evaluated using the QSAR model, where some by-products presented mutagenic and carcinogenic properties.Concentrations and distributions of PAHs and chlorinated aromatic compounds including PCDD/Fs, dl-PCBs, chlorophenols (CPs), and chlorobenzenes (CBz) in the municipal waste incinerator are investigated to characterize their formation and emission via intensive stack sampling. In addition, the toxicity of fly ash contribution by PCDD/Fs and dl-PCBs is evaluated in this study. The results reveal that concentrations of PCDD/Fs and dl-PCBs in flue gas are significantly lower than those of CPs, CBz, and PAHs. Additionally, the removal efficiencies of PAHs and chlorinated aromatic compounds achieved with existing air pollution control devices are evaluated, indicating that the removal efficiencies achieved with activated carbon injection + baghouse (95-99%) are higher than those with semi-dry scrubber (SDS). Besides, PCDD/Fs and PCBs TEQ concentrations in SDS and BH ashes are within 1.61-2.66 WHO-TEQ/g and 0.09-0.19 WHO-TEQ/g, respectively.

The mass flow rates of PCDD/Fs and dl-PCBs after SDS in flue gas are 32.47 mg/h and 49.73 mg/h, respectively. However, the discharge rates of PCDD/Fs and dl-PCBs from SDS are 120.60 mg/h and 27.05 mg/h, respectively, indicating that PCDD/Fs are significantly formed within the SDS. PCDD/Fs formation is attributed to the operating temperature of SDS (240 ± 11.5 °C), which is within the temperature window for de novo synthesis. Thus, operating parameters of the APCDs should be optimized to reduce the formation of PAHs and chlorinated aromatic pollutants from MWI.The goal of this study was to examine breastfeeding behavior and attitudes as predictors of women's body image and weight control behavior. This study extends past research by focusing on positive body image variables including body appreciation and perceived body functionality. Women (N = 597) from the United States who had recently birthed biological babies ages 0-12 months participated in an online study. Current breastfeeding rates were high (86 %), and average breastfeeding duration was approximately 3 months. Women who were currently breastfeeding indicated more positive body images and less likelihood of engaging in maladaptive weight control behaviors than women who were no longer breastfeeding or had never breastfed their baby. Women's positive attitudes toward breastfeeding were associated with awareness and appreciation of body functionality and fewer maladaptive weight control behaviors. These findings extend research on the health benefits of positive body image and suggest that breastfeeding may occur within a constellation of beliefs and behaviors indicative of positive body image.Although women are expected to idealize and achieve hegemonic feminine beauty standards such as being slender and lighter skinned, few studies have examined how women's investment in achieving these restrictive feminine appearance ideals may influence their sexual attitudes and behaviors. Even less is known about Black women. We surveyed 640 Black college women to test hypotheses that endorsement of hegemonic beauty ideals would be positively associated with four dimensions of negative sexual affect (sexual guilt, shame, emotional distancing, and self-consciousness) and negatively associated with two dimensions of sexual agency (sexual assertiveness and satisfaction). Correlation and regression analyses showed that hegemonic beauty ideal acceptance was linked with greater sexual guilt, shame, emotional distancing, and sexual self-consciousness in addition to lower levels of sexual assertiveness and satisfaction. Findings highlight how endorsing restrictive, hegemonic standards of beauty is associated with Black women's reduced sexual affect and sexual agency.Ribosome formation occurs in the nucleolus through interaction with various trans-acting factors. Therefore, hundreds of nucleolar proteins have a function in ribosome formation, although the precise function of each nucleolar protein in ribosome formation is largely unclear. We have previously identified an uncharacterized protein, G-patch domain-containing protein 4 (GPATCH4 or G4), as a component of the pre-ribosomes purified with either nucleolin (NCL) or NPM1. In this present study, we sought to clarify the localization and function of G4. We identified that G4 localizes to both the nucleolus and the Cajal body. Although knockdown of G4 did not have a significant effect on pre-ribosomal RNA processing, cell growth did decrease. Interestingly, G4 knockdown also decreased the number of fibrillar center and dense fibrillar component regions inside the nucleolus. This data has identified G4 as a novel nucleolar protein involved in the regulation of cell growth and nucleolar structure.Synaptic transmission is mediated by neurotransmitters that are stored in synaptic vesicles (SV) and released at the synaptic active zone (AZ). While in recent years major progress has been made in unraveling the molecular machinery responsible for SV docking, fusion and exocytosis, the mechanisms governing AZ protein and SV trafficking through axons still remain unclear. Here, we performed stop-flow nerve ligation to examine axonal trafficking of endogenous AZ and SV proteins. Rat sciatic nerves were collected 1 h, 3 h and 8 h post ligation and processed for immunohistochemistry and electron microscopy. First, we followed the transport of an integral synaptic vesicle protein, SV2A and a SV-associated protein involved in SV trafficking, Rab3a, and observed that while SV2A accumulated on both sides of ligation, Rab3a was only noticeable in the proximal segment of the ligated nerve indicating that only SV trans-membrane protein SV2A displayed a bi-directional axonal transport. We then demonstrate that multiple AZ proteins accumulate rapidly on either side of the ligation with a timescale similar to that of SV2A. Overall, our data uncovers an unexpected robust bi-directional, coordinated -trafficking of SV and AZ proteins in peripheral nerves. This implies that pathological disruption of axonal trafficking will not only impair trafficking of newly synthesized proteins to the synapse but will also affect retrograde transport, leading to neuronal dysfunction and likely neurodegeneration.
