Effects of the pesticide carbendazim on broiler chicken health and carbendazim residue levels in broiler tissues.

Pesticide residues may enter the human body through the food chain when livestock and poultry consume pesticide-contaminated feed. Therefore, monitoring and limiting pesticide residues in animal feed and animal-origin foods is necessary. Carbendazim is one of the most frequently detected pesticides in food and feed and has various toxic effects on non-target animals.

Dietary Bacillus velezensis KNF-209 supplementation improves growth performance, enhances immunity, and promotes gut health in broilers.

This study aimed to investigate the effects of dietary Bacillus velezensis KNF-209 (BV-KNF-209) on the growth performance, immunity, and gut health of broilers. A total of 540 one-day-old male Cobb-500 broilers were randomly divided into 5 groups of 6 replicates with 18 broilers per replicate. Dietary treatments were corn-soybean meal basal diets supplemented with 0, 50, 100, 200, and 400 mg/kg BV-KNF-209 (CON, BV 50, BV 100, BV 200, and BV 400 groups, respectively) for 42 d.

Prevalence of inappropriate use of nirmatrelvir-ritonavir antiviral therapy in hospitalized patients: A multi-centre retrospective study in China.

Background: Nirmatrelvir-ritonavir (NMVr) is a recently developed antiviral agent for treating coronavirus disease 2019 (COVID-19); however, data describing its appropriate use are scarce. This study examined the prevalence of inappropriate use of NMVr in a Chinese hospital setting.

Methods: A multi-centre retrospective chart review was performed for all hospitalized patients who received NMVr between 15 December 2022 and 15 February 2023 in four university-affiliated hospitals in Hangzhou, China.

Conductivity Evaluation of Horizontal Wells in Coalbed Methane Reservoirs: Applicability of Micromaterial Tracer Testing Technology.

Horizontal well-staged fracturing technology is widely used in the exploitation of coalbed methane reservoirs. Most coalbed methane wells have little or no flowback fluid after fracturing due to strong adsorption in the reservoir. The fracture conductivity of each fracturing interval can only be evaluated in the water drainage and gas production stage.

Combined effects of chlorpyrifos and cyfluthrin on neurobehavior and neurotransmitter levels in larval zebrafish.

Chlorpyrifos and cyfluthrin are insecticides commonly used in agriculture. The mixed residues of chlorpyrifos and cyfluthrin in the aquatic environment may have combined effects on nontarget species. Therefore, studying the combined toxic effects and mechanisms of pesticide mixtures is of great significance to environmental risk assessment.

Antagonistic effects and mechanisms of carbendazim and chlorpyrifos on the neurobehavior of larval zebrafish.

Residues from multiple pesticides are frequently detected on vegetables, which may produce combined toxicity not predicted by individual toxicity data. As these combined effects present additional dangers to food safety, we have compared individual to combined effects for a variety of pesticides. Carbendazim and chlorpyrifos are the two most commonly detected pesticides in vegetables, and previous studies reported that combined exposure results in synergistic developmental toxicity to zebrafish embryos.

Antagonistic Effects of Enrofloxacin on Carbendazim-Induced Developmental Toxicity in Zebrafish Embryos.

Carbendazim (CAR) and enrofloxacin (ENF) are frequently detected in fruits and meat products, respectively. Since most people consume fruits, vegetables, and meat products, combined exposure is possible, necessitating further evaluation of toxic interactions. In this study, the developmental toxicity of separate and combined exposure was examined in zebrafish embryos.

[Analysis on the employment of graduates of the Gregg-Turner Training School For Nurses].

There were 35 classes of graduation, altogether 281 graduates from the Gregg-Turner Training School For Nurses during the period 1906 to 1944. The number of graduates increased most rapidly under the influence of civil social, economical and international situation from 1924 to 1938. There were 161 graduates with explicit employment in all the 281 graduates.

[Medical and relieving activities initiated by Guangdong Charity Organizations in the late Qing Dynasty].

The late Qing Dynasty had witnessed the peak of epidemic outbreak in the southern part of China. However, that is also the time when the non-governmental charity activities in Guangdong grew into prosperity. As is shown in the 1909 archives of China's association activities, Guangdong charity organizations at the time played an active role in medical and relieving activities, by using flexible and various means of relief with extensive beneficiaries.

[Evolution of TCM's knowledge on rabies].

The etiology of rabies is caused by the bite of a mad dog infected by non-seasonal pathogen with intoxicated viscerae, and its pathogenesis being heat and blood stasis inside the body. The evolution of the knowledge of rabies experienced a process of from the recognition of biting of a mad dog in the Sui-Tang Dynasties to the systematic manifestations of the central nervous system in the Ming-Qing Dynasties. The recognition in its diagnosis, therapeutic effects, and prognosis is in line with the diagnostic knowledge carried in modern Textbook of Infectious Diseases.
