A forced aeration system for microbial culture of multiple shaken vessels suppresses volatilization
Arch Microbiol. 2024 May 5;206(6):246. doi: 10.1007/s00203-024-03960-2.ABSTRACTShake-flask culture, an aerobic submerged culture, has been used in various applications involving cell cultivation. However, it is not designed for forced aeration. Hence, this study aimed to develop a small-scale submerged shaking culture system enabling forced aeration into the medium. A forced aeration control system for multiple vessels allows shaking, suppresses volatilization, and is attachable externally to existing shaking tables. Using a specially developed plug, medium volatilization was reduced to less than 10%, even after 45 h of co...

Unlocking the potential of SiO < sub > 2 < /sub > and CeO < sub > 2 < /sub > nanoparticles for arsenic mitigation in Vigna mungo L. Hepper (Blackgram)
In this study, the interaction effects of NaAsO2 (1 and 5 μM), SiO2 NPs (10 and 100 mg/L) and CeO2 NPs (10 and 100 mg/L) were assessed in Vigna mungo (Blackgram). The treatment of NaAsO2, SiO2, CeO2-NPs and combinations of NPs & As were applied to blackgram plants under hydroponic conditions. After its application, the morpho-physiological, antioxidant activity, and phytochemical study were evaluated. At 10 and 100 mg/L of SiO2 and CeO2-NPs, there was an increase in antioxidative enzymatic activity (p < 0.05) and reactive oxygen species (ROS). However, substantial ROS accumulation was observed at 1 and 5 μM NaAsO2...

Construction and mechanistic insights of a novel ZnO functionalized rGO composite for efficient adsorption and reduction of Cr(VI)
Environ Sci Pollut Res Int. 2024 May 6. doi: 10.1007/s11356-024-33585-3. Online ahead of print.ABSTRACTA series of ZnO decorated reduced graphene oxide (rGO) (ZnrGOx) with different doping ratios were synthesized by the alkaline hydrothermal method using graphene oxide (GO) and Zn(NO3)2·6H2O as precursors, and subsequently used for the adsorption study of Cr(VI) in water. The morphology, crystalline phase structure, and surface elemental properties of ZnrGOx composites were revealed by XRD, SEM, BET, FT-IR, and XPS characterizations. The results showed that ZnO nanoparticles can be clearly seen on the surface of layered r...

Patient-initiated follow-up in gynaecology: Patient and clinician views
CONCLUSIONS: In this study, both patients and clinicians are in favour of selected use of PIFU in gynaecology services. Both questionnaires found younger patients with benign gynaecological conditions were perceived as best suited PIFU. We recommend offering PIFU to select patients who are confident in self-monitoring, factoring patient choice so patients are not disadvantaged by this system. Further evaluation of PIFU in practice is needed before widespread implementation.PMID:38705009 | DOI:10.1016/j.ejogrb.2024.04.032 (Source: Reproductive Biology)

Intermediate-risk endometrial cancer treated with adjuvant brachytherapy using single dosimetric planning: long-term outcome and toxicity assessment
CONCLUSION: These findings confirm the tolerability of this brachytherapy approach, indicating minimal cases of late grade ≥3 toxicity, associated with a good 5-year OS rate. With the advent of molecular prognostic factors, the current focus revolves around discerning those individuals who gain the greatest benefit from adjuvant therapy, and tailoring treatment more effectively.PMID:38705010 | DOI:10.1016/j.ejogrb.2024.04.040 (Source: Reproductive Biology)

Metritis and the uterine disease microbiome are associated with long-term changes in the endometrium of dairy cows †
Biol Reprod. 2024 May 5:ioae067. doi: 10.1093/biolre/ioae067. Online ahead of print.ABSTRACTCows with metritis (uterine disease) during the first 1 to 2 wk postpartum have lower pregnancy rates when inseminated later postpartum (typically >10 wk). We hypothesized that metritis and the disease-associated uterine microbiome have a long-term effect on endometrial gene expression. Changes in gene expression may inform a mechanism through which disease lowers pregnancy rates. A total of 20 cows were enrolled at 1 to 2 wk postpartum to either metritis (clinical disease; n = 10) or healthy (control; n = 10) groups and randomly...

Exposure to low-concentration fipronil impairs survival, behavior, midgut morphology and physiology of Aedes aegypti larvae
Chemosphere. 2024 May 3:142240. doi: 10.1016/j.chemosphere.2024.142240. Online ahead of print.ABSTRACTThe Aedes aegypti mosquito is a vector for various arboviruses, including dengue and yellow fever. Insecticides, such as pyrethroids and organophosphates, are widely used to manage and control these insects. However, mosquitoes have developed resistance to these chemicals. Therefore, this study aimed to investigate the effects of the commercial formulation of fipronil (Tuit® Florestal; 80% purity) on the survival, behavior, morphology, and proteins related to signaling pathways of the midgut in A. aegypti larvae under con...

Characterization and health risks of short- and medium-chain chlorinated paraffins in the gas and size-fractionated particulate phases in ambient air
Chemosphere. 2024 May 3:142225. doi: 10.1016/j.chemosphere.2024.142225. Online ahead of print.ABSTRACTShort-chain and medium-chain chlorinated paraffins (SCCPs and MCCPs) have garnered significant attention because they have persistence and potential toxicity, and can undergo long-distance transport. Chlorinated paraffins (CPs) inhaled in the size-fractionated particulate phase and gas phase can carry different risks to human health due to their ability to accumulate in different regions of the respiratory tract and exhibit varying deposition efficiencies. In our study, large-volume ambient air samples in both the size-fra...

Recognizing High-Priority Disinfection Byproducts Based on Experimental and Predicted Endocrine Disrupting Data: Virtual Screening and in vitro Study
In this study, we attempt to address this issue. First, a list of relevant DBPs was updated, and 1187 DBPs belonging to 4 main-groups (aliphatic, aromatic, alicyclic, heterocyclic) and 84 subgroups were described. Then, the high-priority endocrine endpoints, DBPs-groups/subgroups, and specific DBPs were determined from 18 endpoints, 4 main-groups, 84 subgroups, and 1187 specific DBPs by a virtual-screening method. The results demonstrate that most of DBPs could not disturb the endocrine endpoints in question because the proportion of active compounds associated with the endocrine endpoints ranged from 0 (human thyroid rece...
