[EX Q]: Context: To evaluate whether tumor invasion depth can be a reliable and easily applicable pathologic assessment strategy to predict outcomes using surgically resected cervical squamous cell carcinoma specimens from patients who have received neoadjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT).', "We included 173 patients with cervical squamous cell carcinoma who received neoadjuvant CCRT (n\u2009=\u2009125) or RT (n\u2009=\u200948) and underwent subsequent radical hysterectomy. Data for the pre-operative clinical International Federation of Gynecology and Obstetrics (FIGO) stage, post-operative pathologic FIGO stage, World Health Organization (WHO) double diameter measurement evaluation, response evaluation criteria in solid tumors (RECIST 1.1) criteria, tumor necrosis rate (TNR), and tumor regression grade (TRG) were investigated to identify correlations with outcomes related to distant metastasis and survival. The tumor invasion depth (TID) and the tumor invasion depth with cytokeratin immunostaining correction (TIDC) at the cervical internal surface were measured to assess their relations to patients' outcomes.", 'Based on measurements taken via transvaginal ultrasound, the pre-operative clinical and post-operative pathologic FIGO staging as well as the WHO double diameter measurement evaluation and RECIST 1.1 criteria were predictive of distant metastasis and survival-related outcomes. Also, lymph node involvement was found to be an independent prognostic factor for recurrence and distant metastasis. Finally, univariate analysis showed both the TID and TIDC were highly related to distant metastasis, overall survival, and progression-free survival, irrespective of the clinical stage of carcinomas.
Answer: The TID or TIDC measured at the cervical internal surface is a useful and easily applied pathologic prognostic factor for distant metastasis and survival outcomes in patients with cervical squamous cell carcinoma treated with neoadjuvant RT or CCRT.
[EX A]: Is tumor invasion depth a useful pathologic assessment for predicting outcomes in cervical squamous cell carcinoma after neoadjuvant radiotherapy?

[EX Q]: Context: To chemically identify and quantify glucose degradation products in heat sterilized fluids for peritoneal dialysis.', 'Three different brands of commercial PD-fluids and one laboratory made fluid, sterilized either by heat or filtration, were investigated for the presence of aldehydes.', 'Aldehydes were identified and quantified using high performance liquid chromatography and gas chromatography.', 'The tested brands of heat sterilized PD-fluids were found to contain several different aldehydes while the sterile filtered PD-fluid contained none. The highest concentrations in commercial PD-fluids of these aldehydes were: acetaldehyde (420 microns), glyoxal (14 microns), methylglyoxal (12 microns) and formaldehyde (11 microns). Valeraldehyde was also identified but not quantified. The presence of 5-HMF (15 microns) and 2-furaldehyde (2 microns), which has been identified by others, was confirmed.
Answer: The heat sterilization of commercial PD-fluids gives rise to several aldehydes which may contribute to adverse effects of PD-fluids on patients.
[EX A]: Does heat sterilization of fluids for peritoneal dialysis give rise to aldehydes?

[EX Q]: Context: Researchers studying the murine response to stress generally use mice housed under standard, nationally mandated conditions as controls. Few investigators are concerned whether basic physical aspects of mouse housing could be an additional source of stress, capable of influencing the subsequent impact of an experimentally applied stressor. We have recently become aware of the potential for housing conditions to impact important physiological and immunological properties in mice.', 'Here we sought to determine whether housing mice at standard temperature (ST; 22\u2009°C) vs. thermoneutral temperature (TT; 30\u2009°C) influences baseline expression of heat shock proteins (HSPs) and their typical induction following a whole body heating.', 'There were no significant differences in baseline expression of HSPs at ST and TT. However, in several cases, the induction of Hsp70, Hsp110 and Hsp90 in tissues of mice maintained at ST was greater than at TT following 6\u2009h of heating (which elevated core body temperature to 39.5\u2009°C). This loss of HSP induction was also seen when mice housed at ST were treated with propranolol, a β-adrenergic receptor antagonist, used clinically to treat hypertension and stress.
Answer: Taken together, these data show that housing temperature significantly influences the expression of HSPs in mice after whole body heating and thus should be considered when stress responses are studied in mice.
