SummaryThirty-eight patients suffering from severe depression were given a course of ECT (Electroconvulsive therapy) in one of three waveforms. These were high-energy sine wave (HS), high-energy pulse (HP), and low-energy pulse (LP). Patients were assigned to one of these treatments on a double-blind basis. The patients were given a battery of memory tests before ECT commenced, after three treatments, at the termination of treatment, and two weeks after the last treatment. The marked improvement in both verbal and nonverbal memory scores was attributed to the lifting of depression. No significant differences were found between the memory scores of the three treatment groups at any point during the treatment period.

This study was designed to examine effects of alterations in energy balance on adaptive changes in components of total energy expenditure (TEE). Nineteen young healthy males were studied during a 10-day sedentary energy balance baseline period and then randomly assigned to one of four 10-day treatment groups: 1) no change in energy intake (EI) or physical activity (PA; energy balance at low energy flux), 2) EI increased by 50% with no change in PA (positive energy balance), 3) TEE increased by 50% by increasing PA, matched by a 50% increase in EI (energy balance at high energy flux), and 4) TEE increased by 50% by increasing PA with no change in EI (negative energy balance). TEE was measured with doubly labeled water, resting metabolic rate (RMR) by indirect calorimetry, and thermic response to feeding (TEF) by indirect calorimetry; energy expenditure of physical activity (EEPA) was estimated by subtracting RMR, TEF, and prescribed PA from TEE. TEE was significantly increased by PA (by design) but not EI. There was a significant main effect of intake and a significant intake-by-activity interaction for changes in RMR. In post hoc analysis, RMR was significantly increased during positive energy balance and energy balance at high energy flux relative to change in RMR when energy balance was maintained at low energy flux. A significant increase in RMR was also noted during negative energy balance after adjustment for change in fat-free mass. There was no significant difference in change in RMR among the three treatment groups.(ABSTRACT TRUNCATED AT 250 WORDS)

The effects of varying levels of dietary energy and protein on gross morphology and histology of testes of FUNNAB – Alpha chickens were studied at the Abubakar Tafawa Balewa University Bauchi, Bauchi state. Twelve cocks were randomly divided into four dietary treatments; Standard diet (SD) (Control) (2650Kcal/Kg ME/ 16%CP), High Energy – Low Protein (HELP, 2800 Kcal/Kg ME/ 14%CP), High Energy – High Protein (HEHP, 2800 Kcal/Kg ME/ 18% CP) and Low Energy – Low Protein (LEHP, 2400 Kcal/Kg ME/ 18%CP) groups. A total of twelve FUNAAB – Alpha cocks were used for this experiment. The cocks were reared in floor pens under natural mating. At 69 weeks of age, all the cocks were slaughtered and testicles carefully removed for gross morphology and histological studies. A significant (P<0.05) influence of diet was noted on live weight with cocks fed HELP diet being heavier (P<0.05) than those in the other treatment groups. Means for all parameters of testicles measured where not different (P>0.05) from each other. Histological sections of the testes showed that HELP diet had mild effect on spermatogenesis evidenced by the scanty spermatozoa in the tubular lumen. It was concluded that FUNAAB – alpha cocks can be fed diets meant for breeding hens without adverse effect on spermatogenesis. However, feeding the LEHP diet produced roosters that were overweighed with slightly impaired spermatogenesis.

SummaryPatients were randomly allocated to treatment with either low energy pulses, high energy pulses, or high energy sinusoidal wave ECT and, despite the induction of convulsions of similar duration, were found to respond at different rates and to a different degree, depending on whether low or high energy currents were used. It is suggested that the quantity of current, as well as the induction of a convulsion, is relevant to therapeutic outcome with ECT. A reexamination of previous work shows that this is not necessarily inconsistent with these findings, which also explain the contradictory results in recent controlled trials of ECT.

IntroductionAcute pancreatitis (AP) is an inflammatory disease with no specific treatment. Mitochondrial injury followed by ATP depletion in both acinar and ductal cells is a recently discovered early event in its pathogenesis. Importantly, preclinical research has shown that intracellular ATP delivery restores the physiological function of the cells and protects from cell injury, suggesting that restoration of energy levels in the pancreas is therapeutically beneficial. Despite several high quality experimental observations in this area, no randomised trials have been conducted to date to address the requirements for energy intake in the early phase of AP.Methods/designThis is a randomised controlled two-arm double-blind multicentre trial. Patients with AP will be randomly assigned to groups A (30 kcal/kg/day energy administration starting within 24 hours of hospital admission) or B (low energy administration during the first 72 hours of hospital admission). Energy will be delivered by nasoenteric tube feeding with additional intravenous glucose supplementation or total parenteral nutrition if necessary. A combination of multiorgan failure for more than 48 hours and mortality is defined as the primary endpoint, whereas several secondary endpoints such as length of hospitalisation or pain will be determined to elucidate more detailed differences between the groups. The general feasibility, safety and quality checks required for high quality evidence will be adhered to.Ethics and disseminationThe study has been approved by the relevant organisation, the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (55961-2/2016/EKU). This study will provide evidence as to whether early high energy nutritional support is beneficial in the clinical management of AP. The results of this trial will be published in an open access way and disseminated among medical doctors.Trial registrationThe trial has been registered at the ISRCTN (ISRTCN 63827758).

Transportation efficiency can be measured in terms of the energy needed to move a person or a tonne of freight over a given distance. For passengers, journey time is important, so an equally useful measure is the product of the energy used and the time taken for the journey. Transportation requires storage of energy. Rechargeable systems such as batteries have very low energy densities as compared to fossil fuels. The highest energy densities come from nuclear fuels, although, because of shielding requirements, these are not practical for most forms of transportation. Liquid hydrocarbons represent a nice compromise between high energy density and ease of use.

Abstract Background This study evaluates oral naproxen and intrauterine instillation of lidocaine for analgesia with intrauterine device (IUD) placement as compared to placebo. Methods This was a randomized, double-blind, placebo-controlled trial. Patients desiring levonorgestrel 52 mg IUD or Copper T380A IUD were randomized into treatment groups. Patients received either oral naproxen 375 mg or placebo approximately 1 h prior to procedure in conjunction with 5 mL of 2% lidocaine or 5 mL of intrauterine saline. The primary outcome was pain with IUD insertion measured on a visual analog scale immediately following the procedure. Prespecified secondary outcomes included physician pain assessment, post procedure analgesia, satisfaction with procedure, satisfaction with IUD, and pain assessment related to IUD type. Results From June 4, 2014 to October 28, 2016 a total of 160 women desiring Copper T380A or levonorgestrel 52 mg intrauterine device insertion and meeting study criteria were enrolled and randomized in the study. Of these, 157 (78 in the Copper T380A arm, 79 in the levonorgestrel 52 mg) received study treatment medication. There were 39 in naproxen/lidocaine arm, 39 in placebo/lidocaine arm, 40 in naproxen/placebo arm, and 39 in placebo/placebo arm. There were no differences in the mean pain scores for IUD placement between treatment groups (naproxen/lidocaine 3.38 ± 2.49; lidocaine only 2.87 ± 2.13; naproxen only 3.09 ± 2.18; placebo 3.62 ± 2.45). There was no difference in self-medication post procedure or in satisfaction with the procedure and IUD among women in the treatment arms or by type of IUD. Conclusion Naproxen with or without intrauterine lidocaine does not reduce pain with IUD placement. Clinical trial registration Clinicaltrials.gov, NCT02769247. Registered May 11, 2016, Retrospectively registered

The complex physical and chemical reactions between the large number of low-energy (0–30 eV) electrons (LEEs) released by high energy radiation interacting with genetic material can lead to the formation of various DNA lesions such as crosslinks, single strand breaks, base modifications, and cleavage, as well as double strand breaks and other cluster damages. When crosslinks and cluster damages cannot be repaired by the cell, they can cause genetic loss of information, mutations, apoptosis, and promote genomic instability. Through the efforts of many research groups in the past two decades, the study of the interaction between LEEs and DNA under different experimental conditions has unveiled some of the main mechanisms responsible for these damages. In the present review, we focus on experimental investigations in the condensed phase that range from fundamental DNA constituents to oligonucleotides, synthetic duplex DNA, and bacterial (i.e., plasmid) DNA. These targets were irradiated either with LEEs from a monoenergetic-electron or photoelectron source, as sub-monolayer, monolayer, or multilayer films and within clusters or water solutions. Each type of experiment is briefly described, and the observed DNA damages are reported, along with the proposed mechanisms. Defining the role of LEEs within the sequence of events leading to radiobiological lesions contributes to our understanding of the action of radiation on living organisms, over a wide range of initial radiation energies. Applications of the interaction of LEEs with DNA to radiotherapy are briefly summarized.
