Pyrethroids are widely used against agricultural pests and human disease vectors due to their broad insecticidal spectrum, fast action, and low mammalian toxicity. Unfortunately, overuse of pyrethroids has led to knockdown resistance (kdr) caused by mutations in voltage-gated sodium channels. Mutation I1011M was repeatedly detected in numerous pyrethroid-resistant Aedes aegypti populations from Latin American and Brazil.

, the striped flea beetle, is one of the most destructive pests in Brassicaceae plants worldwide. Given the drawbacks associated with long-term use of chemical insecticides, green strategies based on chemical ecology are an effective alternative for beetle control. However, the lack of information on beetle ecology has hindered the development of effective biocontrol strategies.

Background: The Asian tiger mosquito, Aedes albopictus, is a competent vector for the spread of several viral arboviruses including dengue, chikungunya, and Zika. Several vital mosquito behaviors linked to survival and reproduction are primarily dependent on a sophisticated olfactory system for semiochemical perception. However, a limited number of studies has hampered our understanding of the relationship between the A.

Aedes aegypti is responsible for transmitting a variety of arboviral infectious diseases such as dengue and chikungunya. Insecticides, particularly pyrethroids, are used widely for mosquito control. However, intensive used of pyrethroids has led to the selection of kdr mutations on sodium channels.

Purpose: To systematically assess the main sociodemographic factors associated with weight perception of adolescents.

Methodology: All studies related to adolescents' weight perception were retrieved from seven databases from January 2001 to July 2022. A total of 13 Medical Subject Headings (MeSH) and keywords were used to identify qualified studies, and reference lists included in the retrieved studies were manually searched to identify potentially relevant publications.

The striped flea beetle, is one of the most destructive pests of Cruciferae crops worldwide. RNA interference (RNAi) is a promising alternative strategy for pest biological control, which overcomes the weakness of synthetic insecticides, such as pest resistance, food safety problems and toxicity to non-target insects. The homolog of Spt16/FACT, plays a critical role in the process of gene transcription, DNA repair, and DNA replication; however, the effects of silencing in remain elusive.

Background: Hypertensive intracerebral hemorrhage (HICH) seriously endangers the quality of life of patients and can even lead to death. Craniotomy is a common treatment method for HICH.

Objective: The aim of this study was to investigate the efficacy of two different sizes of craniotomy in patients with HICH, as well as to evaluate their effects on C-reactive protein (CRP) and blood lactate levels.

Studies have demonstrated that long noncoding RNAs (lncRNAs) are important regulators of intracerebral hemorrhage (ICH) and participants in ICH pathogenesis. We designed this study to probe the potential functions and mechanisms of lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in ICH. The ICH model was established and the rats were treated with MALAT1-shRNA or MALAT1-shRNA+miR-146a inhibitor 1 h after ICH induction.

Matrix microstructure and texture controlling is an important way to optimize Goss ({110}<001>) abnormal grain growth (AGG) in high magnetic induction grain-oriented silicon (Hi-B) steel during primary recrystallization. In the present work, a matrix with homogeneous grain size and favorable texture components was obtained through two-stage normalized annealing followed by primary recrystallization. Furthermore, secondary recrystallization was performed for sharp Goss orientation by slow heating and purified annealing.

Background: Pyrethrum from dry flowers of Chrysanthemum is a well-known botanical insecticide and repellent. Its insecticidal activity attributes to its six insecticidal esters, collectively known as pyrethrins. Pyrethrins and its synthetic analogs pyrethroids exert their toxic action by modifying the function of voltage-gated sodium channels.

Voltage-gated sodium channels are the major targets of several classes of insecticides, including pyrethroids. However, sensitivities of many insect pest species to pyrethroids have gradually decreased due to overuse in pest management programs. One major mechanism of pyrethroid resistance known as knockdown resistance (kdr) involves mutations in the sodium channel gene.

Objective: To investigate the expression levels of matrix metalloproteinases-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in pituitary adenomas (PAs), and to analyze the relationship of the expressions of the two with the prognosis of patients.

Methods: A total of 108 patients with PAs diagnosed in our hospital from May 2010 to May 2012 were selected and divided into the invasive PA (IPA) group (n = 58) and the non-IPA group (n = 50) according to the invasiveness of PAs. Hematoxylin and eosin (H&E) staining was used to observe the pathological state of patients.
