Objective: To assess if there is a relationship between residential radon exposure and two lung cancer histologicaltypes, small-cell carcinoma (diagnosed in people with a smoking history) and adenocarcinoma (the mostcommonly diagnosed histologic type in people who have never smoked) among males and females in ***: With survey data of long-term radon measurements in residential homes, long-term averaged tobaccoconsumption rates in the units of cigarettes per day per person and long-term averaged age-standardized lungcancer incidence rates at provincial level, simple linear fitting (ANOVA linear regression) was applied in this studyto determine the effect on lung cancer induction by smoking and exposure to indoor radon, and to assess if there isa relationship between residential radon exposure and lung cancer histological ***: Lung cancer incidence rates correlate very well with the tobacco consumption rates (P < 0.05). However,females appear to be more likely than males to develop lung cancer at a given amount of cigarette *** both small-cell carcinoma and adenocarcinoma, a statistically significant correlation between incidence rateand mean radon concentration was observed for females, the correlation was much stronger for adenocarcinoma(P = 0.0057) than small-cell carcinoma (P = 0.0483). However, there was no such correlation for ***: It is possible that female non-smokers are more susceptible to radon-induced lung cancer, and the jointeffect of radon exposure and tobacco smoking may be worse in female smokers compared to males, such thathigher incidence rate of adenocarcinoma among females compared to males were observed in recent decades,even though females never smoked more than males.

In the post-COVID-19 pandemic era, the long-term surveillance of pathogens is still important. The rapid detection of pathogens facilitates the accurate and convenient real-time monitoring of microbial contamination and improves the management of diseases. Here, a novel surface plasmon resonance (SPR)-based point of care testing (POCT) approach of microorganism nucleic acids with the guidance of CRISPR enzyme is described, including the application of optical fiber-based detection of trace SARS-CoV2.virus in sewage water on SPR and validation of the plasmonic biosensor for the detection of single-nucleotide mutations in natural water samples.

Post-translational modifications(PTMs)play a critical role in bone remodeling,with phosphorylation and acetylation being particularly well ***,succinylation,a relatively uncommon PTM on lysine,has received considerable research attention for its influence on several physiological and pathological processes and conditions.1 Several substrates involved in mitochondrial pathways have been validated as substrates for the desuccinylase sirtuin 5(Sirt5),a key regulator of succinylation.2.Bone is one of the most metabolically active organs,but the role of succinylation during bone remodeling is not well characterized.
