BACKGROUND: Herniated lumbar discs can induce sciatica by mechanical compression and/or chemical irritation. It was recently reported that neuroglial cellular activity after pulsed radiofrequency (PRF) application to a single dorsal root ganglion (DRG) attenuated neuroglial activity at the corresponding spinal dorsal horn. Recently, caudal epidural PRF has been used to manage neuropathic pain, but evidence of molecular changes after the administration of caudal epidural PRF to attenuate neuropathic pain is lacking, and it has not been determined whether caudal epidural PRF affects neuroglial activity at different spinal levels...

Pain is a significant clinical problem and there is a need for more effective treatments with reduced adverse effects that currently limit the use of mu opioid receptor agonists. Synthetic kappa opioid receptor agonists have no abuse liability and well-documented antinociceptive effects; however, adverse effects (diuresis, dysphoria) preclude their use in the clinic. Combining kappa opioids with non-opioid drugs (cannabinoid receptor agonists) allows for smaller doses of each drug to produce antinociception...

BACKGROUND: Smoking is highly prevalent in patients with schizophrenia. Electronic cigarettes (e-cigarettes) are becoming increasingly popular among smokers. Surveys indicate overall favorable attitudes toward the use of e-cigarettes to reduce or quit smoking, relieve withdrawal symptoms, and with respect to perceived health risks; however, less is known about their use in patients with schizophrenia. In the present study, we investigated the prevalence of and attitudes toward e-cigarettes in patients with schizophrenia...

A 2 × 11 factorial treatment structure was applied in a completely randomized experimental design to investigate differences in noncarcass tissue among serially harvested Holstein steers. Steers ( = 110) were randomly assigned to 1 of 2 dietary treatments: a ration supplemented with zilpaterol hydrochloride (ZH) fed at a rate of 8.3 mg/kg DM for 20 d followed by a 3-d withdrawal or a control ration with no ZH included in the diet. Within treatment, steers were assigned to harvest groups of 254, 282, 310, 338, 366, 394, 422, 450, 478, 506, or 534 d on feed (DOF) prior to initiation of the trial...

An indirect calorimetry trial examined energy metabolism, apparent nutrient digestibility, C retention (CR), and N retention (NR) of cattle supplemented with zilpaterol hydrochloride (ZH). Beef steers ( = 20; 463 ± 14 kg) blocked ( = 5) by weight and source were individually fed and adapted to maintenance energy intake for 21 d before allotment to ZH (90 mg/steer∙d) or no β-adrenergic agonist treatment (control [CONT]) for 20 d (455 ± 14 kg at the start of treatment). Respiration chambers = 4 were used to quantify heat production (HP) during maintenance (d 12 to 16 of the ZH period) and fasting heat production (FHP; d 19 to 20 of ZH period; total 4 d of fast)...

AIMS: Chronic cocaine abuse decreases the inhibitory synaptic transmission via unknown mechanisms, while pharmacologically augmenting gamma-aminobutyric acid-ergic (GABAergic) transmission attenuates cocaine craving. Here, we propose that prolonged cocaine withdrawal downregulates GABAergic transmission and its important regulator gephyrin in medial prefrontal cortex (mPFC), in cocaine-conditioned place-preference (CPP) rats. METHODS: CPP test, patch clamp, and Western blot analysis are engaged to test this proposal...

Indian gooseberry (Emblica officinalis fruit), also known as "Amla" is one of the oldest edible fruits known in India. It has also traditionally been used to treat inflammation, and as an analgesic to treat wounds. However, experimental evidence for the analgesic effects of E. officinalis has been lacking. The present study investigated whether E. officinalis extracts exhibit analgesic effects in the plantar incision (PI) and spared nerve injury (SNI) pain-model rats. We evaluated the mechanical withdrawal threshold (MWT) using von Frey filaments, and pain-related behavior was determined after surgery based on ultrasonic vocalization (USV)...

REVIEW

Schizotypal traits are of interest and importance in their own right and also have theoretical and clinical associations with schizophrenia. These traits comprise attenuated psychotic symptoms, social withdrawal, reduced cognitive capacity, and affective dysregulation. The link between schizotypal traits and psychotic disorders has long since been debated. The status of knowledge at this point is such schizotypal traits are a risk for psychotic disorders, but in and of themselves only confer liability, with other risk factors needing to be present before a transition to psychosis occurs...

BACKGROUND: A 2015 AAST trial reported a 32% mortality for pelvic fracture patients in shock. Angioembolization (AE) is the most common intervention; the Maryland group revealed time to AE averaged 5 hours. The goal of this study was to evaluate the time to intervention and outcomes of an alternative approach for pelvic hemorrhage. We hypothesized preperitoneal pelvic packing (PPP) results in a shorter time to intervention and lower mortality. METHODS: In 2004 we initiated a PPP protocol for pelvic fracture hemorrhage...

BACKGROUND: Active smokers are prevalent within the intensive care setting and place a significant burden on healthcare systems. Nicotine withdrawal due to forced abstinence on admission may contribute to increased agitation and delirium in this patient group. The aim of this systematic review was to determine whether management of nicotine withdrawal, with nicotine replacement therapy (NRT), reduces agitation and delirium in critically ill patients admitted to the intensive care unit (ICU)...

Colistin (Polymyxin E) is one of the few cationic antimicrobial peptides commercialized in both human and veterinary medicine. For several years now, colistin has been considered the last line of defense against infections caused by multidrug-resistant Gram-negative such as Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae. Colistin has been extensively used orally since the 1960s in food animals and particularly in swine for the control of Enterobacteriaceae infections. However, with the recent discovery of plasmid-mediated colistin resistance encoded by the mcr-1 gene and the higher prevalence of samples harboring this gene in animal isolates compared to other origins, livestock has been singled out as the principal reservoir for colistin resistance amplification and spread...

Developmental neuronal cell death and axonal elimination are controlled by transcriptional programs, of which their nature and the function of their components remain elusive. Here, we identified the dual specificity phosphatase Dusp16 as part of trophic deprivation-induced transcriptome in sensory neurons. Ablation of Dusp16 enhanced axonal degeneration in response to trophic withdrawal, suggesting that it has a protective function. Moreover, axonal skin innervation was severely reduced while neuronal elimination was increased in the Dusp16 knockout...

Long term use of steroids results in predictable secondary effects that can lead to increased morbidity and mortality. In this study, we present 10 years' worth of data of early steroid withdrawal (ESW) immunosuppression consisting of Mycophenolate, Sirolimus, and Tacrolimus. From 2003 to 2013, 563 kidney transplant recipients were weaned off steroids prior to discharge. We compared outcomes with that of our 65 historical controls maintained on steroids. We analyzed graft and patient survival and determined the incidence of steroid-related comorbidities such as hypertension, hypercholesterolemia, diabetes, coronary artery disease, and weight gain...

Our goal in using dual induction therapy is to bring the kidney transplant recipient closer (through more effectively timed lymphodepletion) to an optimally immunosuppressed state. Here, we report long-term results of a prospective randomized trial comparing (Group I,N=100) rATG/Dac (3 rATG, 2 Dac doses) vs. (Group II,N=100) rATG/Alemtuzumab(C1H) (1 dose each), using reduced tacrolimus dosing, EC-MPS, and early corticosteroid withdrawal. Lower EC-MPS dosing was targeted in Group II to avoid severe leukopenia...

Nicotinic acid (NiAc) is a potent inhibitor of lipolysis, acutely reducing plasma free fatty acid (FFA) concentrations. However, a major FFA rebound is seen during rapid NiAc washout and sustained exposure is associated with tolerance development, with FFA returning to pretreatment levels. Our aim was to find a rational NiAc dosing regimen which preserves FFA lowering, sufficient to reverse non-adipose tissue lipid accumulation and improve metabolic control, in obese Zucker rats. We compared feeding-period vs...
