This review examines incubated craving that develops over long periods of weeks to months after addictive drug use ends, when rats are given a small priming exposure to the formerly used drug, and a large amount of drug seeking occurs, reflecting large increases in craving over time. Expanded craving occurs when not only the recently-used drug, but other related or unrelated drugs of abuse elicit drug seeking that leads to relapse behavior, including common drugs like caffeine or nicotine, Thus, expanded craving is an increase in the conditions that elicit relapse, such as, a variety of drugs, and it persists weeks after drug use ends. Incubated and expanded craving occur with several drugs of abuse, and these forms of craving, can last for weeks to months and end in relapse. Voluntary physical exercise, blocked incubated cocaine craving, and expanded heroin craving elicited by multiple conditions was reduced in female and male rats. This review examines voluntary physical exercise as a long-term, self-initiated, and self-sustainable treatment that reduces long-term drug craving leading to relapse.
Drugs that increase inhibitory neuronal activity in the brain have been proposed as potential medications for stimulant use disorders.

The present study assessed the ability of chronically administered levetiracetam (Keppra®), a clinically available anticonvulsant drug that increases GABA by binding to synaptic vesicle glycoprotein 2A, to modulate the reinforcing strength of cocaine in monkeys.

Three adult male rhesus monkeys (Macaca mulatta) self-administered cocaine intravenously each day under a progressive-ratio (PR) schedule of reinforcement. Two monkeys also responded to receive food pellets under a 50-response fixed-ratio schedule (FR 50) each morning. After determining a cocaine dose-response curve (0.001-0.3mg/kg per injection, i.v.) in the evening, levetiracetam (5-75mg/kg, p.o., b.i.d.) was administered for 12-16days per dose. To model a treatment setting, cocaine self-administration sessions were conducted using the PR schedule every 4days during levetiracetam treatment. After tapering the dose of levetiracetam over two weeks in the absence of cocaine sessions, cocaine dose-effect curves were re-determined.

Lower doses of levetiracetam produced non-systematic fluctuations in numbers of cocaine injections received in each subject, whereas the highest tested dose significantly increased the reinforcing strength of cocaine; no effects on food-maintained responding were observed. After termination of levetiracetam treatment, dose-effect curves for cocaine self-administration were shifted to the left in two monkeys.

These data suggest that levetiracetam is not likely to be an efficacious pharmacotherapy for cocaine dependence. Rather, sensitivity to cocaine may be increased during and after levetiracetam treatment.

Different approaches to reproduce cerebral palsy (CP) in animals, contribute to the knowledge of the pathophysiological mechanism of this disease and provide a basis for the development of intervention strategies. Locomotion and coordination are the main cause of disability in CP, however, few studies highlight the quantitative differences of CP models, on locomotion parameters, considering the methodologies to cause brain lesions in the perinatal period.

Studies with cerebral palsy animal models that assess locomotion parameters were systematically retrieved from Medline/PubMed, SCOPUS, LILACS, and Web of Science. Methodological evaluation of included studies and quantitative assessment of locomotion parameters were performed after eligibility screening.

CP models were induced by hypoxia-ischemia (HI), Prenatal ischemia (PI), lipopolysaccharide inflammation (LPS), intraventricular haemorrhage (IVH), anoxia (A), sensorimotor restriction (SR), and a combination of different models. Overall, 63 studies ingical refinement, reduction, and replacement in animal experimentation, favoring translational purposes.
To identify an optimal cumulative cisplatin dose along with concurrent chemoradiotherapy (CC-CCD) for children and adolescents with locoregionally advanced nasopharyngeal carcinoma (CALANPC) using real-world data.

Using an NPC-specific database at our center, 157 patients younger than 19years old with non-disseminated CALANPC and receiving neoadjuvant chemotherapy (NAC) plus cisplatin-based concurrent chemoradiotherapy (CCRT) were enrolled. Confounding factors were controlled by conducting propensity score matching analysis. Primary endpoints include disease-free survival (DFS) and distant metastasis-free survival (DMFS).

The optimal threshold for CC-CCD with respect to DFS was 160mg/m
based on recursive partitioning analyses (RPA). selleck chemical Therefore, a uniform threshold of 160mg/m
(≥160 vs. <160mg/m
) was selected to classify patients between high and low CC-CCD groups for survival analysis. Patients receiving low CC-CCD showed a significant decrease in 5-year DFS (76.6% vs 91.3%; P=0.006) and DMFS (81.3% vs 93.5%; P=0.009) compared to those receiving high CC-CCD. Multivariate analyses indicated that high CC-CCD as an favorable prognostic influence for DFS (P=0.007) and DMFS (P=0.008). Further matched analysis identified 65 pairs in both high and low CC-CCD groups. In the matched cohort, high CC-CCD was still identified as a favorable factor for prognosis in DFS (HR, 0.23; 95% CI, 0.08-0.70; P=0.010) and DMFS (HR, 0.23; 95% CI, 0.06-0.82; P=0.023).

CC-CCD exerts significant treatment effects and 160mg/m
CC-CCD may be adequate to provide antitumor effects for CALANPC receiving NAC plus CCRT.

Community onset urinary tract infections (COUTIs) drew attention recently owing to their increased prevalence and associations with resistant pathogens. The study is aimed at investigating the etiology of COUTIs as well as prevalence and the related risk factors of extended-spectrum β-lactamase (ESBL) in COUTIs in China.

The prospective study was performed in nineteen hospitals during November 1, 2017 and August 31, 2019. Non-duplicated isolates from COUTIs were included. The ESBL phenotypic confirmation test was performed and whole genomes were sequenced for all the ESBL-positive bacteria for further analysis. The risk factors for ESBL-producing bacterial infections were analyzed using binary logistic regression.

A total of 1760 COUTI cases were included in this study. Escherichia coli (1332, 75.7%), Klebsiella pneumoniae (110, 6.3%) and Enterococcus faecalis (52, 3.0%) were the top three common pathogens of COUTIs in China. The overall positive rate of ESBLs in Enterobacterales was 37.2% (562/1512). T.
Enterobacterales, especially E. coli, is the most common pathogen in COUTIs in China and ESBL-producers are highly prevalent. Thus, early prediction depending on risk factors seems to be crucial to determine the appropriate empirical therapy for infections caused by ESBL-producing pathogens.Alcoholic liver disease (ALD) is a major cause of morbidity and mortality from liver disorders. Various mechanisms, including oxidative stress and impaired lipid metabolism, have been implicated in the pathogenesis of ALD. Our previous studies showed that nuclear factor erythroid-derived 2-like 2 (Nrf2) is a master regulator of adaptive antioxidant response and lipid metabolism by using a liver-specific Nrf2 knockout (Nrf2(L)-KO) mouse model. In the current study, an ALD model was developed by a Lieber-DeCarli liquid-based ethanol diet given to this Nrf2(L)-KO mouse strain. We found that Nrf2(L)-KO mice were quite sensitive to lethality from 6.3% ethanol diet. We thus decreased the ethanol concentration to 4.2% to obtain tissues to analyze the role of hepatic Nrf2 in the development of ALD. We found that mild hepatic steatosis occurred with both liquid control and 4.2% ethanol diet feeding, which contain 35% fat. Both the fatty acid β-oxidation marker peroxisome proliferators-activated receptor α (PPARα), and lipogenesis regulator PPARγ were reduced with ethanol feeding in Nrf2(L)-KO mice, compared to Nrf2 floxed control mice (Nrf2-LoxP). However, Nrf2(L)-KO livers showed more cell injury than the livers of Nrf2-LoxP mice. Consistent with these data, there was increased proportion of apoptotic cells in the liver of ethanol-fed Nrf2(L)-KO mice comparing Nrf2-LoxP controls. Mechanistically, Nrf2 mediated expression of ethanol detoxification enzymes, such as alcohol dehydrogenase 1 and aldehyde dehydrogenase1a1, likely contributed to the sensitivity to ethanol toxicity. In conclusion, hepatic Nrf2 is critical to the development of ALD, particularly the morbidity and liver injury.
This study was carried out to investigate the effect of microRNA miR-532-5p on the proliferation of hypertension endothelial cells.

Angiotensin II (Ang II)-treated human umbilical vein endothelial cells (HUVECs) and primary human aortic endothelial cells (HAECs) were used as cell models to imitate the pathological changes in endothelial cells under hypertensive conditions. The expression levels of miR-532-5p and programmed cell death protein 4 (PDCD4) were detected by Quantitative Real-time PCR (qRT-PCR). The effects of miR-532-5p and PDCD4 on the proliferation of HUVECs and HAECs treated with Ang II were detected by Methyl Thiazolyl Tetrazolium (MTT) assay. The effects of miR-532-5p and PDCD4 on the apoptosis and cell cycle of HUVECs and HAECs treated with Ang II were detected by flow cytometry. Western blot was used to detect the expression levels of PDCD4, apoptosis-related proteins and cycle-related proteins in HUVECs and HAECs treated with Ang II. Bioinformatics analysis and Luciferase gene reporter assay were used to assess the relationship between miR-532-5p and PDCD4.

The expression levels of miR-532-5p were reduced, while the expression levels of PDCD4 were raised in Ang II-treated HUVECs and HAECs. MiR-532-5p mimic and si-PDCD4 restrained the apoptosis, promoted the proliferation of Ang II-treated HUVECs and HAECs and caused S-phase arrest of cells. PDCD4 was identified as a potential target for miR-532-5p. Knockdown of PDCD4 significantly affected apoptosis and proliferation of Ang II-treated HUVECs. MiR-532-5p regulates apoptosis and proliferation of Ang II-induced HUVECs and HAECs. In addition, overexpression of PDCD4 attenuated the effect of miR-532-5p on the proliferation of Ang II-treated HUVECs and HAECs.

MiR-532-5p inhibited the expression of PDCD4, thereby inhibiting apoptosis and promoting proliferation of Ang II-treated HUVECs and HAECs.
