    Progressive hemifacial atrophy also known as Parry-Romberg syndrome is an acquired, slowly progressive disorder, occurring more in women, primarily affecting one side of the face, mainly characterized by unilateral atrophy, and loss of skin and subcutaneous tissues of face, muscles, and bones. Ocular and neurologic involvements are common. The possible etiology is unclear without any known cure. We report a rare case of Parry-Romberg syndrome with classical features. The clinical features, radiological imaging findings, differential diagnosis, and available treatment options are discussed in this report. PMID:26492117

    Full Text Available The Parry Romberg syndrome (PRS is a rare neurocutaneous disorder characterized by progressive facial hemiatrophy. Parry Romberg syndrome is characterized by a slow progressive atrophy that appears in the early stages of life, primarily affecting the subcutaneous tissue and subjacent fat on one side of the face. Dental findings include delayed tooth eruption, retarded root formation, root resorption, oligodontia, microdontia, dilacerations, pulp stones, reduction in the height and width of the ramus and body of the mandible, and delayed mandibular angular development. We describe the case of a 24-year-old female patient with stabilized, moderate, facial hemiatrophy on the right side of her face with a varied presentation.

    Full Text Available In the arena of free-fighting, traditional blocking techniques and grappling entries often don’t work as well as the simple parry. The parry—a refinement of the “slap away” motion that most combatants employ instinctively when confronted with an attack—is a critical tool in the martial artist’s armamentarium, yet it has received surprisingly little scrutiny in the research and writing of the arts. Having been students and teachers of various striking and grappling arts for over twenty years, Robert Wolfe and Peter Hobart have pooled their experience to develop a step-by-step approach to understanding and applying the parry in a variety of ways. Part One focuses on the use of the parry primarily in striking engagements; Part Two in the context of grappling.

    Full Text Available Parry-Romberg syndrome is a rare neurocutaneous disorder of unknown origin. It is characterized by progressive facial hemiatrophy and frequently overlaps with a condition known as linear scleroderma ‘en coup de sabre’. Neurological involvement is frequently described in these patients, including migraine, facial pain and epilepsy, which represent the commonest neurological conditions, sometimes associated with brain abnormalities ipsilaterally to the skin lesions. We present a case of Parry-Romberg syndrome with neurological involvement in a patient with diagnosed localized scleroderma (morphea.

    Parry-Romberg syndrome is a rare clinical entity characterised by progressive hemifacial atrophy with appearance of 'saber'. Various neurological and otorhinolaryngological disorders are associated with this syndrome. The association of Parry -Romberg syndrome with Spasmodic dysphonia has rarely been reported. A 37 year old female presented with progressive atrophy of tissues of left side of face for 10 years and change in voice for 1 year. On examination, wasting and atrophy of tissues including tongue was noted on left side of the face. ENT examination revealed adductor spasmodic dysphonia. We report the rare association of Parry -Romberg syndrome with spasmodic dysphonia.

    2017-10-01

    Full Text Available Parry-Romberg syndrome or progressive hemifacial atrophy is a craniofacial disorder characterized by slow and progressive atrophy, generally unilateral, of facial tissues including muscles, bones and skin. The coup de sabre is a clear line of demarcation seen between the normal and abnormal structures. The severity of the facial deformity is dependent on the age of onset of the disease. Cosmetic management is the only available treatment and has to be delayed until facial growth is completed. The present case report deals with a 43-year-old woman with progressive hemifacial atrophy which started from the age of 10 months. Despite almost complete involvement of the right paramedian area and the early age of onset, she had neither eye changes nor any dental malformations.

    2011-01-01

    Lines of code (LOC) analysis is one of the methods used to measure programmer productivity and estimate schedules of programming projects. The Launch Control System (LCS) had previously used this method to estimate the amount of work and to plan development efforts. The disadvantage of using LOC as a measure of effort is that one can only measure 30% to 35% of the total effort of software projects involves coding [8]. In the application, instead of using the LOC we are using function point for a better estimation of hours in each software to develop. Because of these disadvantages, Jamie Szafran of the System Software Branch of Control And Data Systems (NE-C3) at Kennedy Space Canter developed a web application called Function Point Analysis (FPA) Depot. The objective of this web application is that the LCS software architecture team can use the data to more accurately estimate the effort required to implement customer requirements. This paper describes the evolution of the domain model used for function point analysis as project managers continually strive to generate more accurate estimates.

    Progressive facial hemiatrophy (PFH), Parry-Romberg syndrome, is a rare disorder frequently associated with epilepsy. We describe a 28-year-old man who had PFH and partial epilepsy that was easily controlled with antiepileptic drugs. In accordance with this patient's benign course of seizures, the cortical silent period was prolonged in the symptomatic hemisphere. This finding may represent compensatory interictal mechanisms in epilepsy.

    2015-07-01

    Full Text Available The Parry-Romberg syndrome is a rare degenerative disease of unknown etiology that has dental implications. It is characterized by a progressive hemifacial atrophy that appears in the early stages of life. It causes aesthetic, functional and psychological alterations, and has social implications for the patient. There is no definitive treatment for the Parry-Romberg syndrome. Systemic and immune alterations produce oral and maxillofacial manifestations, which need to be managed by specialized dental professionals. The aim of this paper is to do a literature review of the Parry-Romberg syndrome and describe the oral and clinical characteristics of this condition in a 12-year-old male pediatric patient, who had a history of neurological disorders and facial asymmetry on the left side. Dentists require an adequate knowledge of the clinical and dental characteristics of this syndrome. With early diagnosis and appropriate surgical and orthodontic treatment at an early age, they can improve the quality of life of patients and minimize invasive long-term effects.

    Full Text Available Parry-Romberg syndrome (PRS is a rare, poorly understood degenerative condition characterized by atrophic changes affecting one side of the face. The cause of these changes remains obscure. Migraine and facial pain such as trigeminal neuralgia are the most common neurological symptoms in this patient group. Sometimes, it causes epilepsy and rarely cerebral hemiatrophy, meningeal thickening, cortical dysgenesis, calcified lesions, aneurysms, and intracranial vascular malformations. Herein, the author reports the first case of PRS with multiple large intracranial cysts producing raised intracranial pressure.

    Full Text Available Progressive facial hemiatrophy, also known as Parry-Romberg syndrome, is a progressive andself-limited deformation of the subcutaneous tissue volume on one side of the face thatcreates craniofacial asymmetry. We present the case of a patient with a five-year historyof progressive right facial hemiatrophy, who underwent facial volumetric restoration usingcell-assisted lipotransfer (CAL, which consists of an autologous fat graft enriched withadipose-derived stem cells (ASCs extracted from the same patient. ASCs have the capacityto differentiate into adipocytes. They also promote angiogenesis, release angiogenic growthfactors, and some can survive as stem cells. The use of autologous fat as a filler in soft tissueatrophy has been satisfactory in patients with mild and moderate Parry-Romberg syndrome.Currently, CAL has showed promising results in the long term by decreasing the rate of fatreabsorption. The permanence and stability of the graft in all the injected areas has showedthat autologous fat grafts enriched with stem cells could be a promising technique for thecorrection of defects caused by this syndrome.

  20. Network technology for depot modernization

    Hostick, C.J.

    1990-12-01

    This report was prepared by the Pacific Northwest Laboratory to summarize existing and emerging information system technology and standards applicable to Depot System Command (DESCOM) modernization efforts. The intent of this summarization is to provide the Revitalization of Army Depots for the Year 2000 (READY 2000) team a clear understanding of the enabling information system technologies required to support effective modernization activities. Much of the information contained in this report was acquired during the last year in support of the US Army Armament, Munitions, and Chemical Command (AMCCOM) Facility Integrated Manufacturing Management System (FIMMS) project at PNL, which is targeting the modernization of plant-wide information systems at Army Ammunition Plants. The objective of information system modernization is to improve the effectiveness of an organization in performing its mission. Information system modernization strives to meet this objective by creating an environment where data is electronically captured near the source and readily available to all areas of the organization. Advanced networks, together with related information system technology, are the enabling mechanisms that make modern information system infrastructures possible. The intent of this paper is to present an overview of advanced information system network technology to support depot modernization planners in making technology management decisions. Existing and emerging Open System Interconnection (OSI) and Government Open System Interconnection Profile (GOSIP) standards are explained, as well as a brief assessment of existing products compliant with these standards. Finally, recommendations for achieving plant-wide integration using existing products are presented, and migration strategies for full OSI compliance are introduced. 5 refs., 16 figs. (JF)

    2012-01-01

    A space transportation infrastructure is described that utilizes propellant depot servicing platforms to support all foreseeable missions in the Earth-Moon vicinity and deep space out to Mars. The infrastructure utilizes current expendable launch vehicle (ELV) systems such as the Delta IV Heavy, Atlas V, and Falcon 9, for all crew, cargo, and propellant launches to orbit. Propellant launches are made to Low-Earth-Orbit (LEO) Depot and an Earth-Moon Lagrange Point 1 (L1) Depot to support a new reusable in-space transportation vehicles. The LEO Depot supports missions to Geosynchronous Earth Orbit (GEO) for satellite servicing and to L1 for L1 Depot missions. The L1 Depot supports Lunar, Earth-Sun L2 (ESL2), Asteroid and Mars Missions. New vehicle design concepts are presented that can be launched on current 5 meter diameter ELV systems. These new reusable vehicle concepts include a Crew Transfer Vehicle (CTV) for crew transportation between the LEO Depot, L1 Depot and missions beyond L1; a new reusable lunar lander for crew transportation between the L1 Depot and the lunar surface; and Mars orbital Depot are based on International Space Station (ISS) heritage hardware. Data provided includes the number of launches required for each mission utilizing current ELV systems (Delta IV Heavy or equivalent) and the approximate vehicle masses and propellant requirements. Also included is a discussion on affordability with ideas on technologies that could reduce the number of launches required and thoughts on how this infrastructure include competitive bidding for ELV flights and propellant services, developments of new reusable in-space vehicles and development of a multiuse infrastructure that can support many government and commercial missions simultaneously.

  2. Parry-Romberg syndrome with hemimasticatory spasm in pregnancy; A dystonia mimic

    Akhila Kumar Panda

    2014-01-01

    Full Text Available Parry-Romberg syndrome (PRS with hemimasticatory spasm (HMS is quite an uncommon overlapping phenomenon which very often mimics jaw closing dystonia. A previously healthy 35-year-old female, during her 5 th month of pregnancy started developing intermittent unilateral painful spasms of jaw while conversation, clinching of teeth, or eating, which led to frequent tongue bites. The spasms were worsened during pregnancy. She used to do certain manoeuvre like sensory tricks in form of touching involved side of the face to relieve the symptoms. Apart from this, she developed progressive hemifacial and hemitongue atrophy. Other medical and neurological examinations were normal. Laboratory investigations as well as neuroimaging were noncontributory. The spasm responded to carbamazepine but hemifacial atrophy persists. To our best knowledge, onset and worsening of this syndrome in pregnancy has not been described earlier which might be correlated either with some hormonal imbalance or some unknown mechanisms.

    We reviewed the literature on published cases of progressive facial hemiatrophy (Parry-Romberg syndrome) to identify possible pathophysiological mechanisms of the syndrome. To describe the somatosensory phenotype of a previously unreported patient with progressive facial hemiatrophy and facial pain. Case report and 4-month follow-up period. University-based tertiary referral headache center. A 37-year-old woman with progressive facial hemiatrophy and strictly left-sided facial pain over 12 years. Greater occipital nerve blockade with lidocaine, 2% (2 mL), and methylprednisolone sodium phosphate (80 mg). Trigeminal sensory phenotype on quantitative sensory testing using thermal threshold and Von Frey hairs. The case report includes patient photographs, neuroimaging, and neurophysiological findings. On the left side, there was continuous pain in V(1) and V(2) and intermittent sharp shooting pains in V(3). The sensory examination showed areas on the left side with pinprick hyperalgesia, cold and heat hyperalgesia, and dynamic mechanical allodynia. The pain in V(1) and V(3) and the allodynia dramatically improved after greater occipital nerve blockade. In the cases reported in the literature, a constant component of the pain was always part of the phenotype, and positive or negative trigeminal sensory signs were frequently described. The phenotype of our patient suggests neuropathic pain involving all 3 branches of the trigeminal nerve, and the patient fulfills newly defined stricter criteria for neuropathic pain. Similar to our case, phenotypes of the other published cases seem to agree with trigeminal neuropathic pain rather than trigeminal neuralgia specifically.

    Lamers, Patrick; Roni, Mohammad S; Tumuluru, Jaya S; Jacobson, Jacob J; Cafferty, Kara G; Hansen, Jason K; Kenney, Kevin; Teymouri, Farzaneh; Bals, Bryan

    2015-10-01

    Decentralized biomass processing facilities, known as biomass depots, may be necessary to achieve feedstock cost, quantity, and quality required to grow the future U.S. bioeconomy. In this paper, we assess three distinct depot configurations for technical difference and economic performance. The depot designs were chosen to compare and contrast a suite of capabilities that a depot could perform ranging from conventional pelleting to sophisticated pretreatment technologies. Our economic analyses indicate that depot processing costs are likely to range from ∼US$30 to US$63 per dry metric tonne (Mg), depending upon the specific technology implemented and the energy consumption for processing equipment such as grinders and dryers. We conclude that the benefits of integrating depots into the overall biomass feedstock supply chain will outweigh depot processing costs and that incorporation of this technology should be aggressively pursued.

    2016-01-01

    Neurologic involvement is well recognized in Systemic Scleroderma and increasingly reported in Localized Scleroderma. MRI brain abnormalities are often associated with symptoms such as seizures or headaches. In some cases they may be clinically silent. We describe a 23 years old female with head, trunk and limbs scleroderma who developed Parry-Romberg Syndrome. Brain MRI showed ipsilateral temporal lobe atrophy without any prominent neurologic symptoms. Neuropsychological examination revealed Mild Cognitive Impairment. During the 7 years of follow up we have noticed progression of face atrophy but no progression of brain atrophy. Cognitive functions have been stable. This case highlight that major MRI brain abnormalities in LS may occur with only subtle clinical manifestation such as Mild Cognitive Impairment.

    Austin, J.E.

    1993-01-01

    I determined the fatty acid composition of subcutaneous, abdominal, visceral, and leg saddle depots in adult female Canada Geese (Branta canadensis) wintering in north-central Missouri during October 1984-March 1985. Mean levels of C14:0, C16:0, C16:1, C18:0, C18:1, C18:2, and C18:3 generally were highest in the subcutaneous and abdominal depots. The ratio of saturated to unsaturated fats was highest in the leg saddle depot and lowest in the abdominal depot. I also assessed the differences among sexes, seasons, and years in fatty acid composition of abdominal fat depots in adult geese collected during October-March, 1985-1987. Adult females had consistently higher levels of C14:0 in abdominal depots than males. Fatty acid composition of the abdominal depot differed among years but not by season. In the abdominal depot, C14:0, C16:0, C16:1, and C18:1 were higher in 1986-1987 compared with the previous two years, whereas C18:3 was highest in 1984-1985. Differences among years reflected changes in winter diet. Fatty acids of wintering geese were similar to those previously found in breeding Canada Geese.

For each piece of equipment entered into the database, complete location, service, maintenance, modification, certification, and radiation exposure histories can be maintained. To facilitate data entry accuracy, efficiency, and consistency, barcoding technology has been used extensively. DEPOT has been an important tool in improving the reliability of the microsystems controlling SLC. This document describes the components of the DEPOT database, the elements in the database records, and the use of the supporting programs for entering data, searching the database, and producing reports from the information.

  15. Locating Depots for Capacitated Vehicle Routing

    DEFF Research Database (Denmark)

    Gørtz, Inge Li; Nagarajan, Viswanath

    2016-01-01

    We study a location-routing problem in the context of capacitated vehicle routing.

    Abarelix [Abarelix-Depot-F, Abarelix-Depot-M, Abarelix-L, PPI 149, R 3827, Plenaxis] is a peptide consisting of natural and artificial amino acids. In females, abarelix is an estrogen production antagonist with potential for the treatment of breast cancer, endometriosis and other reproductive hormone diseases. In males it is a testosterone production antagonist and has potential as hormonal therapy of prostate cancer. Depot formulations of abarelix (abarelix-depot-M and abarelix-depot-F) are being developed for hormonally responsive prostate cancer and endometriosis, respectively. Clinical development of the depot formulations is currently being conducted by Praecis Pharmaceuticals, the originators of the agent. A non-depot formulation, abarelix-L, was also being conducted for prostate gland volume reduction. Praecis Pharmaceuticals has entered into a number of licensing agreements covering abarelix. However, all agreements have since been terminated leaving Praecis to develop and commercialise the agent on its own. The terminated agreements include an agreement between Praecis and Roche for the commercialisation of abarelix in the US. This agreement was terminated in November 1998. Praecis Pharmaceuticals also entered into a collaborative agreement with Amgen in March 1999, whereby the companies would develop abarelix and Amgen would commercialise the drug in the US, Canada, Australia, Asia and several secondary markets. However, in September 2001, Praecis and Amgen announced that they were terminating the agreement for all indications. Praecis stated at the time that it remained committed to developing abarelix for both prostate cancer and endometriosis. Amgen had submitted 'Lotestrol' to the US Patent and Trademarks Office as a possible tradename for abarelix-depot-M. Lotestrol may also have been under consideration as a tradename for abarelix-depot-F. Praecis had also sold European, African, Latin American and Middle Eastern rights to abarelix to Sanofi

    Ongoing climate change in the Arctic is causing drastic alteration of the Arctic marine ecosystem functioning, such as shifts in patterns of primary production, and modifying the present tight pelagic-benthic coupling. Subsequently benthic communities, which rely upon organic matter produced in the top layers of the Ocean, will also be affected by these changes. The benthic megafaunal communities play a significant role in ecological processes and ecosystem functioning (i.e. organic matter recycling, bioturbation, food source for the higher trophic levels…). Yet, information is scarce regarding the main food sources for dominant benthic organisms, and therefore the impact of the ongoing changes is difficult to assess. The goal of this study is to investigate the preferential feeding of different carbon sources by megabenthic organisms in the Canadian High Arctic and to identify environmental drivers which explain the observed trends. In summer 2013, benthic megafauna was collected at 9 stations spread along latitudinal (58 to 81°N) and longitudinal (62 to 114°W) transects in the Baffin Bay and Parry Channel, respectively. Carbon and nitrogen bulk stable isotope analyses (δ13C and δ15N) were performed on several species divided into groups according to their feeding type. This study highlights distinct trends in δ13C values of benthic organisms suggesting the importance of both phytoplankton and ice algae as carbon sources for megafauna in the Canadian High Arctic. The importance of physical and biological parameters as drivers of food web structure will be furthermore discussed.

    We study a location-routing problem in the context of capacitated vehicle routing. The input is a set of demand locations in a metric space and a fleet of k vehicles each of capacity Q. The objective is to locate k depots, one for each vehicle, and compute routes for the vehicles so that all demands are satisfied and the total cost is minimized. Our main result is a constant-factor approximation algorithm for this problem. To achieve this result, we reduce to the k-median-forest problem, which generalizes both k-median and minimum spanning tree, and which might be of independent interest. We give a (3+c)-approximation algorithm for k-median-forest, which leads to a (12+c)-approximation algorithm for the above location-routing problem, for any constant c>0. The algorithm for k-median-forest is just t-swap local search, and we prove that it has locality gap 3+2/t; this generalizes the corresponding result known for k-median. Finally we consider the "non-uniform" k-median-forest problem which has different cost ...

    Peptide drugs for antineoplastic therapies usually have low oral bioavailability and short in vivo half-lives, requiring less preferred delivery methods. Lanreotide depot is a sustained-release somatostatin analog (SSA) formulation produced via an innovative peptide self-assembly method. Lanreotide is approved in the USA and Europe to improve progression-free survival (PFS) in patients with unresectable gastroenteropancreatic neuroendocrine tumors (GEP-NETs) and also approved in Europe for symptom control in carcinoid syndrome associated with GEP-NETs. This review discusses how the distinct molecule and formulation of lanreotide depot provide advantages to patients and health care providers, as well as the most recent clinical evidence demonstrating the safety and efficacy of lanreotide depot in inhibiting tumor growth and controlling hormonal symptoms in GEP-NETs. The lanreotide depot formulation confers a remarkable pharmacokinetic profile with no excipients, comprised only of lanreotide acetate and water. Of note, lanreotide depot constitutes an example for peptide self-assembly based formulations, providing insights that could help future development of sustained-release formulations of other antineoplastic peptides. Most patients with GEP-NETs will present with inoperable or incurable disease; thus, medical management for symptoms and tumor control plays a crucial role. Recent long-term clinical studies have demonstrated that lanreotide depot is well tolerated, prolongs PFS in GEP-NET patients, and significantly reduces symptoms related to carcinoid syndrome. The unique depot formulation and delivery method of lanreotide confer advantages in the treatment of metastatic GEP-NETs, contributing to improvements in NET-related symptoms and PFS without reducing quality of life in this patient population.

    Parry-Romberg syndrome (PRS) is a rare craniofacial disease that causes progressive hemifacial atrophy of the soft tissue before spontaneously entering remission. Autologous fat grafting may provide a less invasive alternative, producing aesthetically pleasing results while avoiding the need for traditional microsurgical free flap coverage. A systematic review of the literature was conducted. Inclusion and exclusion criteria were applied. The case report highlights the technique using two-dimensional and three-dimensional photography. Our review yielded 31 articles in addition to our case describing 147 cases of lipofilling to correct PRS soft-tissue defects. Patients underwent an average of 2.2 procedures, receiving on average 95 mL of grafted fat. Disease severity was classified into mild (41%), moderate (42%), and severe (17%) in the identified patients. Increasing disease severity correlated with an increasing number of procedures and fat-grafting volumes to achieve adequate aesthetic outcomes (mean, 1.5 and 38 mL; 2.3 and 81 mL; 3.7 and 129 mL, respectively). Reported benefits over flap-based reconstructions included reductions in cost (40%), operative time (50%), donor-site morbidity (52%), and rate of complications (33%). Aesthetic benefits cited included improved skin quality (65%), more natural contours (1%), and more natural facial expressions (10%). Fat grafting for correction of PRS-associated soft-tissue defects is receiving heightened acceptance for its ability to restore natural facial contours. While additional fat-grafting procedures may be required with increased disease severity, autologous fat grafting may be a beneficial option as a sole modality to correct PRS-associated soft-tissue atrophy.

  6. Revalidation of Pyxicephalus angusticeps Parry, 1982 (Anura: Natatanura: Pyxicephalidae), a bullfrog endemic to the lowlands of eastern Africa.

    Pyxicephalus currently contains three recognized species, viz. P. adspersus, P. edulis and P. obbianus, the former two of which have a long history of confusion. Parry (1982) described P. adspersus angusticeps from Beira, Mozambique, which was synonymized with P. edulis. We re-examine the taxonomic status of Pyxicephalus taxa from Mozambique, examining the types and contrasting them to congeners throughout Africa. Morphological characters previously used to delimit species in Pyxicephalus are examined, and problems with some identified. Additional diagnostic characters and their variation in Pyxicephalus are discussed, and a revised key is provided. Confusion among species in the genus, type localities, literature and folklore led to P. adspersus angusticeps being incorrectly synonymized with P. edulis. We formally revalidate P. angusticeps, and designate a lectotype for P. edulis. The identity of voucher specimens from previous work suggests that the breeding ecology of P. angusticeps is distinct from that of P. adspersus and P. edulis, and that the advertisement call of P. angusticeps was used as part of the evidence for elevating P. edulis out of synonymy with P. adspersus. The previous confusion of P. adspersus and P. edulis does not affect the recognition of P. angusticeps. The wider implication of the previous misidentification of P. angusticeps as P. edulis is that most of the museum material labeled as P. adspersus from East Africa is P. edulis, and most of the museum material labeled as P. edulis from East Africa is P. angusticeps. This conclusion has been confirmed from East African museum material thus far examined.

  7. Architecture Study for a Fuel Depot Supplied from Lunar Assets

    Perrin, Thomas M.; Casler, James G.

    2016-01-01

    This architecture study sought to determine the optimum architecture for a fuel depot supplied from lunar assets. Four factors - the location of propellant processing (on the Moon or on the depot), the depot location (on the Moon, L1, GEO, or LEO), the propellant transfer location (L1, GEO, or LEO), and the propellant transfer method (bulk fuel or canister exchange) were combined to identify 18 candidate architectures. Two design reference missions (DRMs) - a commercial satellite servicing mission and a Government cargo mission to Mars - created demand for propellants, while a propellant delivery DRM examined supply issues. The study concluded Earth-Moon L1 is the best location for an orbiting depot. For all architectures, propellant boiloff was less than anticipated, and was far overshadowed by delta-v requirements and resulting fuel consumption. Bulk transfer is the most flexible for both the supplier and customer. However, since canister exchange bypasses the transfer of bulk cryogens and necessary chilldown losses, canister exchange shows promise and merits further investigation. Overall, this work indicates propellant consumption and loss is an essential factor in assessing fuel depot architectures.

    The Database of Environmental Parameters, Organizations, and Tools (DEPOT) has been developed by the Department of Energy (DOE) as a central warehouse for access to data essential for environmental risk assessment analyses. Initial efforts have concentrated on groundwater and vadose zone transport data and bioaccumulation factors. DEPOT seeks to provide a source of referenced data that, wherever possible, includes the level of uncertainty associated with these parameters. Based on the amount of data available for a particular parameter, uncertainty is expressed as a standard deviation or a distribution function. DEPOT also provides DOE site-specific performance assessment data, pathway-specific transport data, and links to environmental regulations, disposal site waste acceptance criteria, other environmental parameter databases, and environmental risk assessment models.

    After 1 year of introduction of olanzapine long-acting injectable (LAI) in India, many psychiatrists believe that it is a very affordable, well-tolerated, and effective second generation long-acting antipsychotic depot compared to not well tolerated but cheap first generation antipsychotic depots and to other second generation depots which are costly. However, reports of its possible adverse events in clinical settings are not yet published. We report what probably might be the first case of postinjection delirium/sedation syndrome (PDSS) in India. Although the occurrence is uncommon, incorrect understanding of this event may hinder the future use of the potentially useful olanzapine LAI. We review the available literature on the proposed diagnostic guidelines, mechanism of this event, precautions, and management of PDSS. PMID:27570354

The activity of hypothalamic-pituitary-adrenal axis plays a key role in pregnancy. Such naturally stimulated endogenous corticosteroid hormones are free from unwanted side effects of their synthetics analogs. Low level of maternal blood ACTH and insufficient increase of induced by hypothalamic hormones oxytocinases (cystine-β-aminopeptidases were indication to ACTH-depot therapy (0.5 mg/week in our consecutive prospective studies. Contrary to antenatal use of synthetic corticosteroids, there are no temporal limits of this therapy, which has to be more often recommended into clinical prevention of fetal morbidity, treatment of premature delivery, and finally elimination of the newborn's mortality caused by the neuroendocrinological gestoses.

    Human milk is the preferred choice for infant feeding. When a sick or premature infant's own mother's milk is unavailable, donor human milk is becoming more widely used. Many potential milk donors do not live within close proximity to the 10 North American not-for-profit milk banks. Transporting milk via commercial carriers can be inconvenient and costly for recipient banks. A network of donor human milk depots is one practical way to increase the quantity of available donor human milk. This article provides guidelines and practical suggestions for establishing a donor human milk depot.

    Full Text Available Abstract Background Hemifacial atrophy (Parry-Romberg syndrome is a relatively rare disease. The etiology of the disease is not clear. Some authors postulate its relation with limited scleroderma linearis. Linear scleroderma "en coup de sabre" is characterized by clinical presence of most commonly one-sided linear syndrome. In a number of patients, neurological affection is the medium of the disease. The treatment of both scleroderma varieties is similar to the treatment of limited systemic sclerosis. Case presentation We present two cases of a disease: a case of a 49-year-old woman with a typical image of hemifacial atrophy, without any changes of the nervous system and a case of a 33-year-old patient with an "en coup de sabre" scleroderma and with CNS tumor. Conclusion We described typical cases of a rare diseases, hemifacial atrophy and "en coup de sabre" scleroderma. In the patient diagnosed with Parry-Romberg syndrome, with Borrelia burgdoferi infection and with minor neurological symptoms, despite a four-year case history, there was a lack of proper diagnosis and treatment. In the second patient only skin changes without any neurological symptoms could be observed and only a precise neurological diagnosis revealed the presence of CNS tumor.

    A document describes a conceptual transportation system that would support exploratory visits by humans to locations dispersed across the surface of the Moon and provide transport of humans and cargo to sustain one or more permanent Lunar outpost. The system architecture reflects requirements to (1) minimize the amount of vehicle hardware that must be expended while maintaining high performance margins and (2) take advantage of emerging capabilities to produce propellants on the Moon while also enabling efficient operation using propellants transported from Earth. The system would include reusable single- stage lander spacecraft and a depot in a low orbit around the Moon. Each lander would have descent, landing, and ascent capabilities. A crew-taxi version of the lander would carry a pressurized crew module; a cargo version could carry a variety of cargo containers. The depot would serve as a facility for storage and for refueling with propellants delivered from Earth or propellants produced on the Moon. The depot could receive propellants and cargo sent from Earth on a variety of spacecraft. The depot could provide power and orbit maintenance for crew vehicles from Earth and could serve as a safe haven for lunar crews pending transport back to Earth.

    To determine the indications of long-acting antipsychotic injection and what its effectiveness and safety in adult patients with schizophrenia during the treatment maintenance phase. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. The evidence of NICE guide 82 was adopted and updated. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. The literature review shows that the evidence has moderate to low quality. 8 articles were used. The risk of relapse was lower with depot risperidone and paliperidone palmitate when compared with placebo. For the risk of hospitalizations comparing depot antipsychotics (APD) versus oral AP, the result is inconclusive. Globally the second-generation APD had a lower risk of discontinuation when compared with placebo. The second generation AP had higher risk of extrapyramidal syndromes than placebo, as in the use of antiparkinsonian. The comparison of second-generation AP injections versus placebo showed an increased risk of early weight gain. The use of depot antipsychotics in the maintenance phase of adult patients diagnosed with schizophrenia is recommended if there is no adherence to oral antipsychotics as the patient's preference. It is not recommended depot antipsychotics in the acute phase of schizophrenia in adults. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

  9. Buserelin-depot in the treatment of prostate cancer

    2015-01-01

    Full Text Available The high incidence of prostate cancer (PC and the considerably wide use of hormone therapy for its treatment as an individual modalityfor its advanced forms (Т3–Т4, N1, M1, recurrences, and progression after local treatments (radical prostatectomy, radiation therapy and for combined treatment as neoadjuvant and adjuvant therapies determine the importance of a sufficient range of hormonal drugs at an urologic oncologist’s disposal. Among the luteinizing hormone-releasing hormone (LHRH agonists, there is rather long-known Buserelin made in Russia, the clinical efficacy of which is highly competitive with foreign analogs. The paper presents the results of a 3-month trial of the efficiency and safety of Buserelin depot treatment in 20 patients aged 53 to 87 years with morphologically verified PC. The patients with PC showed a gradual decrease in the mean values of prostate-specific antigen (PCA from81.2 to 27.8 and 23.0 ng / ml at 2 and 3 months of Buserelin depot therapy, respectively. The performed therapy could achieve reductions in testosterone levels from 168 ng / dl at baseline to 21 and 19.8 ng / dl postcastration at 1 and 3 months of the therapy.All the patients tolerated Buserelin depot therapy without having clinically significant adverse reactions. The most common complaints were hyperhidrosis and hot flushes, which are typical of all LHRH agonists and which are not marked in the treatment with other drugs of this group.Conclusion. Buserelin depot 3.75 mg is a highly effective Russian drug to treat hormone-dependent PC. Its administration causes a reduction in PSA levels and ensures a steady decline in serum testosterone concentrations to the postcastration level without causing serious side effects. The findings do not differ from those when foreign LHRH analogues are used.

    2011-12-01

    Full Text Available Background: Benzene, toluene, ethylbenzene and xylene (BTEX are the most important toxic volatile compounds in the air and could be easily absorbed through the respiratory tract. In recent years, the risk of exposure to BTEX compounds, especially benzene as a carcinogen, has been considered in petroleum depot stations. Objective: To assess the occupational exposure of petroleum depot workers in Iran to BTEX compounds. Methods: After completing a questionnaire and assessing occupational exposure to BTEX compounds, 78 (46 exposed and 32 non-exposed depot workers were randomly selected to participate in this study. Air sampling and analysis of BTEX was conducted according to the NIOSH method No. 1501. Analysis of urinary hippuric acid, as an indicator of toluene exposure, was carried out according to NIOSH method No. 8300. Personal monitoring of the high exposure group to BTEX compounds was repeated to verify the results obtained in the first phase of the monitoring. Results: Among the 9 operating groups studied, occupational exposure to benzene and toluene was higher in quality control and gasoline loading operators—the median exposure ranged from 0.16 to 1.63 ppm for benzene and 0.2 to 2.72 ppm for toluene. Median exposure of other group members to BTEX compounds was below the detection limit of analytical method (0.07, 0.06, 0.05, and 0.05 ppm, respectively. The level of toluene exposure measured showed correlation with neither post-shift urinary hippuric acid (Spearman's rho=0.128, p=0.982 nor with the difference between post- and pre-shift urinary hippuric acid (Spearman's rho=0.089, p=0.847 in depot operational workers. Conclusion: Gasoline loading operators are exposed to a relatively high level of benzene.

  18. Gas production and transport in artificial sludge depots.

    Science.gov (United States)

    van Kessel, T; van Kesteren, W G M

    2002-01-01

    This paper presents a study to determine the impact of gas production in dredging sludge on the storage capacity of artificial sludge depots. Gas is produced as a result of the decomposition of organic material present in dredging spoil. This process, in which methane and carbon dioxide are formed, may lead to expansion of sludge layers, partly or even completely counterbalancing consolidation. The study shows that, even with a very conservative estimation of the rate of gas production, accumulation of gas occurs as convective and diffusive transport proceed very slowly. Nucleation of gas bubbles occurs already at a limited oversaturation of pore water. During their growth, bubbles push aside the surrounding grain matrix. Resulting stresses may initiate cracks around bubbles. If these cracks join, they may form channels stretching out to the depot surface and along which gas may escape. However, channels are only stable to a limited depth below which bubble accumulation may continue. The gas content at which sufficient cracks and channels are formed to balance the rate of gas production with the rate of outflow strongly depends on the constitutive properties of the dredging sludge considered. In sludge with a high shear strength (> 10 kPa), stable channels are created already at low deformations. However, a large expansion may occur in sludge with a low strength. The present study shows that accumulation of gas may continue until a bulk density less than that of water is attained. This is equivalent to a gas fraction of about 25-37%, depending on the initial water content of the sludge. Only then can gas escape as a result of instabilities in the sediment matrix. This should be well taken into account during the design and management of artificial depots.

    2017-01-01

    Depot effects were found to be accompanying phenomena of membrane separation processes. Accumulation of target species in the membrane matrix during feasibility tests can hamper proper conclusions or compromise the filtration results. Therefore, we investigated the effects of delayed membrane release of chlorogenic acid and caffeine, considered as key compounds of interest in spent coffee products’ recovery treatment. Permeate fluxes and key components release were studied in course of 24 hours via nanofiltration of pure solvent, both immediately after the mock solution filtration and after idle stay. Conclusions are drawn and recommendations advised for proper analysis of experimental data on membrane screening.

  6. From neutrophils to macrophages: differences in regional adipose tissue depots.

    Science.gov (United States)

    Dam, V; Sikder, T; Santosa, S

    2016-01-01

    Currently, we do not fully understand the underlying mechanisms of how regional adiposity promotes metabolic dysregulation. As adipose tissue expands, there is an increase in chronic systemic low-grade inflammation due to greater infiltration of immune cells and production of cytokines. This chronic inflammation is thought to play a major role in the development of metabolic complications and disease such as insulin resistance and diabetes. We know that different adipose tissue depots contribute differently to the risk of metabolic disease. People who have an upper body fat distribution around the abdomen are at greater risk of disease than those who tend to store fat in their lower body around the hips and thighs. Thus, it is conceivable that adipose tissue depots contribute differently to the inflammatory milieu as a result of varied infiltration of immune cell types. In this review, we describe the role and function of major resident immune cells in the development of adipose tissue inflammation and discuss their regional differences in the context of metabolic disease risk. We find that although initial studies have found regional differences, a more comprehensive understanding of how immune cells interrupt adipose tissue homeostasis is needed.

    2008-10-01

    In the fast-developing logistics and supply chain management fields, one of the key problems in the decision support system is that how to arrange, for a lot of customers and suppliers, the supplier-to-customer assignment and produce a detailed supply schedule under a set of constraints. Solutions to the multi-depot vehicle scheduling problems (MDVRP) help in solving this problem in case of transportation applications. The objective of the MDVSP is to minimize the total distance covered by all vehicles, which can be considered as delivery costs or time consumption. The MDVSP is one of nondeterministic polynomial-time hard (NP-hard) problem which cannot be solved to optimality within polynomial bounded computational time. Many different approaches have been developed to tackle MDVSP, such as exact algorithm (EA), one-stage approach (OSA), two-phase heuristic method (TPHM), tabu search algorithm (TSA), genetic algorithm (GA) and hierarchical multiplex structure (HIMS). Most of the methods mentioned above are time consuming and have high risk to result in local optimum. In this paper, a new search algorithm is proposed to solve MDVSP based on Artificial Immune Systems (AIS), which are inspirited by vertebrate immune systems. The proposed AIS algorithm is tested with 30 customers and 6 vehicles located in 3 depots. Experimental results show that the artificial immune system algorithm is an effective and efficient method for solving MDVSP problems.

    Full Text Available This paper addresses the linehaul-feeder vehicle routing problem with virtual depots and time windows (LFVRPTW. Small and large vehicles deliver services to customers within time constraints; small vehicles en route may reload commodities from either the physical depot or from the larger vehicle at a virtual depot before continuing onward. A two-stage solution heuristic involving Tabu search is proposed to solve this problem. The test results show that the LFVRPTW performs better than the vehicle routing problem with time windows in terms of both objective value and the number of small vehicles dispatched.

The findings are based on data from three participating centres in Thailand and one in Mexico. A relative risk for cervical cancer of 1.2 was observed in women who had ever used DMPA; this was not statistically significant. No consistent increase in risk with duration of use was observed, although a relative risk of 2 was found in women who had used DMPA for more than 5 years. This observed increase in risk was confined to women who were aged under 46 years or who had first been exposed to DMPA before 30 years of age. These findings are based on small numbers of subjects, and may not represent a causal relationship. PMID:2931205

    Full Text Available Manufacturing processes are becoming increasingly automated. Introduction of innovative solutions often necessitate processing very large number of signals from various devices. Correctness tests of the components configuration becomes a compiled operation requiring vast expenditure of time and knowledge. The models may be a mathematical reflection of the actual object. Many actions can be computer-assisted to varying degree. One example is construction of simulation models. These can also be simulation models developed in advanced software. The stages of creating a model may be purely random. This paper aims at a closer analysis of the simulation model based on the high storage sheet depot modeling using Plant Simulation software. The results of analysis can be used for optimization, but this stage is a separate issue.

  12. The case for a centralized repair depot for Space Shuttle

    Enlow, R. D.

    1985-01-01

    The first priority of the NSTS program is to make the Space Shuttle system fully operational and cost effective in providing routine access to space. In support of this priority an integrated logistics support system was planned, structured and is being implemented to support a launch-on-time goal of 95 percent. In achieving a 95 percent spares 'fill rate' in an environment of small fleet size, highly unique and high cost assets, significant spares cost can be incurred. A major portion of these costs are for the additional spares required when repair or acquisition times are lengthy. This paper provides a fundamental analysis of the costs and other factors involved in the spare and repair process and provides an optimized cost and process solution for the Space Shuttle program - a centralized repair depot located at KSC.

    2014-03-01

    Obesity, characterized by excessive adiposity, is a risk factor for many metabolic pathologies, such as type 2 diabetes mellitus (T2DM). Numerous studies have shown that adipose tissue distribution may be a greater predictor of metabolic health. Upper-body fat (visceral and subcutaneous abdominal) is commonly associated with the unfavorable complications of obesity, while lower-body fat (gluteal-femoral) may be protective. Current research investigations are focused on analyzing the metabolic properties of adipose tissue, in order to better understand the mechanisms that regulate fat distribution in both men and women. This review will highlight the adipose tissue depot- and sex-dependent differences in white adipose tissue function, including adipogenesis, adipose tissue developmental patterning, the storage and release of fatty acids, and secretory function. This article is part of a Special Issue entitled: Modulation of Adipose Tissue in Health and Disease.

    Full Text Available High-bay depot plays an important role in the storage industry. Due to large and high space of high-bay depot, it is difficult to make temperature distribution uniform, which will influence the storage time of raw materials. In this paper, the aim is to find the reasonable air supply and energy-saving method; a supply-air method of high-bay depot is investigated as an example. The results show the radius and spacing of the supply-air inlet have great influence on temperature distribution. The temperature nonuniformity coefficient of summer is smaller than that of winter. The investigated results can provide a theoretical reference for the high-bay depot design and economic operation.

    Full Text Available Abstract Background The co-morbidities of obesity are tied to location of excess fat in the intra-abdominal as compared to subcutaneous white adipose tissue (WAT depot. Genes distinctly expressed in WAT depots may impart depot-dependent physiological functions. To identify such genes, we prepared subtractive cDNA libraries from murine subcutaneous (SC or intra-abdominal epididymal (EP white adipocytes. Results Differential screening and qPCR validation identified 7 transcripts with 2.5-fold or greater enrichment in EP vs. SC adipocytes. Boc, a component of the hedgehog signaling pathway demonstrated highest enrichment (~12-fold in EP adipocytes. We also identified a dramatic enrichment in SC adipocytes vs. EP adipocytes and in SC WAT vs. EP WAT for transcript(s for the major urinary proteins (Mups, small secreted proteins with pheromone functions that are members of the lipocalin family. Expression of Boc and Mup transcript was further assessed in murine tissues, adipogenesis models, and obesity. qPCR analysis reveals that EP WAT is a major site of expression of Boc transcript. Furthermore, Boc transcript expression decreased in obese EP WAT with a concomitant upregulation of Boc transcript in the obese SC WAT depot. Assessment of the Boc binding partner Cdon in adipose tissue and cell fractions thereof, revealed transcript expression similar to Boc; suggestive of a role for the Boc-Cdon axis in WAT depot function. Mup transcripts were predominantly expressed in liver and in the SC and RP WAT depots and increased several thousand-fold during differentiation of primary murine preadipocytes to adipocytes. Mup transcripts were also markedly reduced in SC WAT and liver of ob/ob genetically obese mice compared to wild type. Conclusion Further assessment of WAT depot-enriched transcripts may uncover distinctions in WAT depot gene expression that illuminate the physiological impact of regional adiposity.

  1. Pilot-Scale Demonstration of In-Situ Chemical Oxidation ...

    Science.gov (United States)

    A pilot-scale in situ chemical oxidation (ISCO) demonstration, involving subsurface injections of sodium permanganate (NaMnO4), was performed at the US Marine Corp Recruit Depot (MCRD), site 45 (Parris Island (PI), SC). The ground water was originally contaminated with perchloroethylene (PCE) (also known as tetrachloroethylene), a chlorinated solvent used in dry cleaner operations. High resolution site characterization involved multiple iterations of soil core sampling and analysis. Nested micro-wells and conventional wells were also used to sample and analyze ground water for PCE and decomposition products (i.e., trichloroethyelene (TCE), dichloroethylene (c-DCE, t-DCE), and vinyl chloride (VC)), collectively referred to as chlorinated volatile organic compounds (CVOC). This characterization methodology was used to develop and refine the conceptual site model and the ISCO design, not only by identifying CVOC contamination but also by eliminating uncontaminated portions of the aquifer from further ISCO consideration. Direct-push injection was selected as the main method of NaMnO4 delivery due to its flexibility and low initial capital cost. Site impediments to ISCO activities in the source area involved subsurface utilities, including a high pressure water main, a high voltage power line, a communication line, and sanitary and stormwater sewer lines. Utility markings were used in conjunction with careful planning and judicious selection of injection locations. A

    OBJECTIVE--To determine whether use of the injectable contraceptive depot medroxyprogesterone acetate (Depo-Provera) affects the risk of breast cancer in women. DESIGN--A population based case-control study. SETTING--Nationwide community study. SUBJECTS--891 Women aged 25-54 with newly diagnosed breast cancer were compared with 1864 women selected at random from the electoral rolls. INTERVENTION--Women were interviewed by telephone about past use of contraceptives and about possible risk factors for breast cancer. MAIN OUTCOME MEASURE--Relative risk of breast cancer in women who had used medroxyprogesterone. RESULTS--Medroxyprogesterone had been used by 110 patients and 252 controls. Overall, the relative risk of breast cancer associated with any duration of use was 1.0 (95% confidence interval 0.80 to 1.3). In women aged 25-34 the relative risk was 2.0 (1.0 to 3.8). The relative risk was highest in women aged 25-34 who had used the drug for six years or longer, although there were few women in this category. Women who had used it for two years or longer before age 25 had an increased risk of breast cancer (relative risk 4.6; 1.4 to 15.1). CONCLUSION--Despite the lack of an overall association these findings suggest that medroxyprogesterone may increase the risk of breast cancer in young women. PMID:2529939

    This paper presents background, experimental design, and preliminary experimental results for the liquid hydrogen bubble point tests conducted at the Cryogenic Components Cell 7 facility at the NASA Glenn Research Center in Cleveland, Ohio. The purpose of the test series was to investigate the parameters that affect liquid acquisition device (LAD) performance in a liquid hydrogen (LH2) propellant tank, to mitigate risk in the final design of the LAD for the Cryogenic Propellant Storage and Transfer Technology Demonstration Mission, and to provide insight into optimal LAD operation for future LH2 depots. Preliminary test results show an increase in performance and screen retention over the low reference LH2 bubble point value for a 325 2300 screen in three separate ways, thus improving fundamental LH2 LAD performance. By using a finer mesh screen, operating at a colder liquid temperature, and pressurizing with a noncondensible pressurant gas, a significant increase in margin is achieved in bubble point pressure for LH2 screen channel LADs.

    Objective Our main objective was to compare the regulation of cortisol production within omental (Om) and abdominal subcutaneous (Abd sc) human adipose tissue. Methods and Procedures Om and Abd sc adipose tissue were obtained at surgery from subjects with a wide range of BMI. Hydroxysteroid dehydrogenase (HSD) activity (3H-cortisone and 3H-cortisol interconversion) and expression were measured before and after organ culture with insulin and/or dexamethasone. Results Type 1 HSD (HSD1) mRNA and reductase activity were mainly expressed within adipocytes and tightly correlated with adipocyte size within both depots. There was no depot difference in HSD1 expression or reductase activity, while cortisol inactivation and HSD2 mRNA expression (expressed in stromal cells) were higher in Om suggesting higher cortisol turnover in this depot. Culture with insulin decreased HSD reductase activity in both depots. Culture with dexamethasone plus insulin compared to insulin alone increased HSD reductase activity only in the Om depot. This depot-specific increase in reductase activity could not be explained by an alteration in HSD1 mRNA or protein, which was paradoxically decreased. However, in Om only, hexose-6-phosphate dehydrogenase (H6PDH) mRNA levels were increased by culture with dexamethasone plus insulin compared to insulin alone, suggesting that higher nicotinamide adenine dinucleotide phosphate-oxidase (NADPH) production within the endoplasmic reticulum (ER) contributed to the higher HSD reductase activity. Discussion We conclude that in the presence of insulin, glucocorticoids cause a depot-specific increase in the activation of cortisone within Om adipose tissue, and that this mechanism may contribute to adipocyte hypertrophy and visceral obesity.

    Metro depots are where subway trains are parked and where maintenance is carried out. They usually occupy the largest ground areas in metro projects. Due to land utilization problems, Chinese cities have begun to develop over-track buildings above metro depots for people's life and work. The frequently moving trains, when going into and out of metro depots, can cause excessive vibration and noise to over-track buildings and adversely affect the living quality of the building occupants. Considering the current need of reliable experimental data for the construction of metro depots, field measurements of vibration and noise on the ground and inside a nearby 3-story building subjected to moving subway trains were conducted in a metro depot at Guangzhou, China. The amplitudes and frequency contents of velocity levels were quantified and compared. The composite A-weighted equivalent sound levels and maximum sound levels were captured. The predicted models for vibration and noise of metro depot were proposed based on existing models and verified. It was found that the vertical vibrations were significantly greater than the horizontal vibrations on the ground and inside the building near the testing line. While at the throat area, the horizontal vibrations near the curved track were remarkably greater than the vertical vibrations. The attenuation of the vibrations with frequencies above 50 Hz was larger than the ones below 50 Hz, and the frequencies of vibration transmitting to adjacent buildings were mainly within 10-50 Hz. The largest equivalent sound level generated in the throat area was smaller than the testing line one, but the instantaneous maximum sound level induced by wheels squeal, contact between wheels and rail joints as well as turnout was close to or even greater than the testing line one. The predicted models gave a first estimation for design and assessment of newly built metro depots.

    In 2000 and 2001 studies were conducted at the NASA Marshall Space Flight Center on the technical requirements and commercial potential for propellant production depots in low Earth orbit (LEO) to support future commercial, NASA, and other Agency missions. Results indicate that propellant production depots appear to be technically feasible given continued technology development, and there is a substantial growing market that depots could support. Systems studies showed that the most expensive part of transferring payloads to geosynchronous orbit (GEO) is the fuel. A cryogenic propellant production and storage depot stationed in LEO could lower the cost of missions to GEO and beyond. Propellant production separates water into hydrogen and oxygen through electrolysis. This process utilizes large amounts of power, therefore a depot derived from advanced space solar power technology was defined. Results indicate that in the coming decades there could be a significant demand for water-based propellants from Earth, moon, or asteroid resources if in-space transfer vehicles (upper stages) transitioned to reusable systems using water based propellants. This type of strategic planning move could create a substantial commercial market for space resources development, and ultimately lead toward significant commercial infrastructure development within the Earth-Moon system.

    Somatostatin analogs (SSAs) are a mainstay therapy for the treatment of carcinoid syndrome associated with neuroendocrine tumors (NETs). They are effective for a range of gastroenteropancreatic NETs (GEP-NETs). Lanreotide depot (Somatuline®) is an SSA that is approved for the treatment of GEP-NETs to improve progression-free survival (PFS). The article reviews the efficacy, safety, and administration of lanreotide depot and relates those attributes to considerations and preferences of oncology nurses and their patients. A review of the literature on the use of lanreotide for the treatment of NETs and carcinoid syndrome was conducted. In addition, the literature on drug delivery and routes of administration was surveyed to provide context for comparative studies related to clinical and patient preferences. Lanreotide depot prolongs PFS and is well tolerated by patients who expressed satisfaction in the ability to control symptoms related to carcinoid syndrome. Nurses cited several benefits to using lanreotide depot in the clinical setting, including more time saved to address other patient care issues. Attributes of lanreotide depot-including its efficacy, safety and tolerability, dosing and administration, and cost-may contribute to healthcare decisions regarding the treatment and management of NETs.

    Recently a role of adipose tissue as an endocrine organ secreting factors involved in the regulation of whole-body energy homeostasis has emerged. Preadipocytes in different fat depots have distinct adipogenic potential and the metabolic activity differs between mature adipocytes of different depot origins. Here we describe the proliferation and differentiation of stromal-vascular cells derived from subcutaneous and visceral fat depots of adult pigs. We demonstrate that subcutaneous porcine preadipocytes proliferate more actively and that individual subcutaneous adipocytes have a more rapid accumulation of triacylglycerols than visceral cells. During differentiation, subcutaneous and visceral preadipocytes showed similar gene expression patterns with increased expression of adiponectin (APM1), adipocyte-specific fatty acid binding protein (FABP4), catalase (CAT), and peroxisome proliferator-activated receptor gamma 2 (PPARG2). Furthermore, initial data showing depot-originated effects on the expression of CAT, carnitine palmitoyl transferase 1B (CPT1B) and FABP4 suggest possible depot specific differences in the function and metabolism of mature porcine adipocytes.

    The effects of depot medroxyprogesterone (DMPA), a 5 alpha-reductase, luteinizing-hormone release and human androgen receptor adhesion inhibitor, were assessed in 80 patients with benign prostatic hyperplasia (BPH) in a double-blind, placebo-controlled study. Patients were randomized to DMPA 150 mg single-dose intramuscular injection or placebo in a similar fashion. The following changes were seen with DMPA after 3 months (duration of DMPA effect): (1) serum testosterone reached castration levels within 3 days as compared to no changes in the placebo group; (2) the prostate volume was reduced by 25% compared to a 3% decrease with placebo (p < 0.001); (3) maximum urinary-flow rates increased by 3.7 ml/s compared to placebo (p < 0.001); (4) total urinary symptom scores decreased by 4.9 points compared to a nonsignificant decrease with placebo (p < 0.005). There was a 2.5-point decrease in irritative symptoms (urinary frequency, nocturia and urgency) as compared to a nonsignificant decrease with placebo (p < 0.005). After 3 months, the urinary symptoms and urodynamic changes were reversed but significantly greater than the baseline values (p < 0.001). The prostates showed regrowth to the initial sizes within 18-36 weeks. DMPA was better tolerated, except for a higher incidence of impotence, decreased libido and ejaculatory disorders, than in the placebo group. The quality of life is improved with DMPA since it did not produce hot flashes. It was concluded that single-dose DMPA 150 mg is a safe and effective treatment for prostatic obstruction where potency is a secondary consideration.

    OBJECTIVE--To determine if the use of the injectable contraceptive depot medroxyprogesterone (DMPA), which reduces ovarian oestrogen production, is associated with changes in bone density. DESIGN--Population study. DMPA users were compared with two control groups selected from larger population studies and individually matched for several putative determinants of bone density (age, race, body mass index, and years of oestrogen deficiency). Controls and DMPA users were matched without prior knowledge of their bone density measurements. SETTING--Teaching hospital and community family planning clinics. SUBJECTS--30 current users of DMPA with a minimum five years' previous use, 30 premenopausal controls, and 30 postmenopausal controls. MAIN OUTCOME MEASURE--Lumbar spine and femoral neck bone mineral density assessed by dual energy x ray absorptiometry. RESULTS--Compared with premenopausal controls matched for age, race, and body mass index, DMPA users had significantly reduced bone density in the lumbar spine (mean difference 7.5% (95% confidence interval 1.9% to 13.1%), p = 0.002) and in the femoral neck (6.6%, (0.8% to 12.3%), p = 0.007). Compared with postmenopausal controls matched for body mass index and duration of oestrogen deficiency, DMPA users had greater bone density in the lumbar spine (8.9% (4.3% to 13.5%), p = 0.001), but in the femoral neck the difference in bone density was less (4.0% (-0.4% to 8.5%), p = 0.04). CONCLUSIONS--Women using DMPA have bone density values intermediate between those of normal premenopausal and postmenopausal controls; thus, the degree of oestrogen deficiency induced by DMPA may have an adverse effect on bone density.

    This paper considers a multi-depot vehicle routing problem with pickup and delivery requests. In the problem of interest, each location may have goods for both pickup and delivery with multiple delivery locations that may not be the depots. These characteristics are quite common in industrial practice. A particle swarm optimization algorithm with multiple social learning structures is proposed for solving the practical case of multi-depot vehicle routing problem with simultaneous pickup and delivery and time window. A new decoding procedure is implemented using the PSO class provided in the ETLib object library. Computational experiments are carried out using the test instances for the pickup and delivery problem with time windows (PDPTW) as well as a newly generated instance. The preliminary results show that the proposed algorithm is able to provide good solutions to most of the test problems.

  13. A 3/2-Approximation Algorithm for Multiple Depot Multiple Traveling Salesman Problem

    Xu, Zhou; Rodrigues, Brian

    As an important extension of the classical traveling salesman problem (TSP), the multiple depot multiple traveling salesman problem (MDMTSP) is to minimize the total length of a collection of tours for multiple vehicles to serve all the customers, where each vehicle must start or stay at its distinct depot. Due to the gap between the existing best approximation ratios for the TSP and for the MDMTSP in literature, which are 3/2 and 2, respectively, it is an open question whether or not a 3/2-approximation algorithm exists for the MDMTSP. We have partially addressed this question by developing a 3/2-approximation algorithm, which runs in polynomial time when the number of depots is a constant.

    Depot antipsychotics have been generally used in patients with chronic schizophrenia with adherence problems to oral therapy. However, it has been suggested they can be a good alternative in earlier stages too. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified three systematic reviews including two pertinent randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded it is not clear whether there are differences between depot and oral antipsychotics in first-episode psychosis because the certainty of the available evidence is very low.

The Centers for Disease Control and Prevention estimates that 68.5% of Americans, including 63.9% of adult women older than 20 years, are overweight (body mass index between 25 kg/m2 and 29.9 kg/m2 or obese (body mass index >30 kg/m2. In light of this, it is not surprising that the rates of bariatric surgery have also been increasing. When considering the metabolic changes associated with both bariatric surgery and contraceptive use, in combination with the unique medical considerations of obese women, it is indisputable that clear guidelines are needed when counseling obese patients of reproductive age after bariatric surgery. In this literature review, we focus on depot medroxyprogesterone acetate (DMPA and the implications of its use in obese women, preweight and postweight loss following bariatric surgery. Both DMPA use and bariatric surgery are known to cause bone loss, but it is still unclear whether there is an additive effect of the two factors on bone loss and whether either of these factors directly leads to an increased risk of bone fracture. The current consensus guidelines do not impose a restriction on the use of DMPA after bariatric surgery. DMPA use is associated with weight gain, and it is unclear whether weight loss blunting occurs with the use of DMPA after bariatric surgery. Prior studies had demonstrated an association with weight gain in adolescents, and therefore, those prescribing DMPA use after bariatric surgery in adolescents should proceed with caution. Adult women do not have a similar response to the use of DMPA. DMPA use has rarely been associated with increased risk of venous thromboembolism (VTE. The

    Full Text Available Objective: Appropriate dosage of the long-acting depot gonadotrophin releasing hormone (GnRH agonist has not been determined in long protocol for IVF, and one-third-dose depot triptorelin was compared with half-dose in a luteal long protocol of in-vitro fertilization/ intra cytoplasmic sperm injection (IVF/ICSI treatment in this study. Materials and Methods: This is a prospective, randomized, open clinical trial. 100 patients were randomized into two groups. Group I received one-third-dose (1.25 mg depot triptorelin. Group II received half-dose (1.87 mg. The clinical and experimental parameters were compared between the two groups. Results: There was no premature luteinizing hormone (LH surge in both groups. On Day 3-5 of menstrual cycle after down-regulation, fewer patients showed low-level LH (<1.0 IU/L and estradiol (<30 pg/mL in group I (P <0.05. There were fewer oocytes retrieved (P =0.086, fewer total embryos and available embryos for cryopreservation in Group I (P <0.05, while good-quality embryo rate was higher in group I (P <0.05. The length and dose of ovarian stimulation was lower in Group I, but not significantly. The clinical pregnancy (52% versus 40%, implantation (48% versus 37.5%, delivery (46% versus 32%, or live birth (42% versus 32% rates and the abortion (8% versus 20% rates showed no significant differences. Conclusion: Depot triptorelin 1.25 mg can be successfully used with reduced pituitary suppression and lower cost in a long protocol for in-vitro fertilization.

    Nanoscale drug depots, comprising a drug reservoir surrounded by a carrier membrane, are much sought after in contemporary pharmaceutical research. Using cellulose acetate (CA) as a filament-forming polymeric matrix and ferulic acid (FA) as a model drug, nanoscale drug depots in the form of core-shell fibers were designed and fabricated using a modified tri-axial electrospinning process. This employed a solvent mixture as the outer working fluid, as a result of which a robust and continuous preparation process could be achieved. The fiber-based depots had a linear morphology, smooth surfaces, and an average diameter of 0.62±0.07μm. Electron microscopy data showed them to have clear core-shell structures, with the FA encapsulated inside a CA shell. X-ray diffraction and IR spectroscopy results verified that FA was present in the crystalline physical form. In vitro dissolution tests revealed that the fibers were able to provide close to zero-order release over 36h, with no initial burst release and minimal tailing-off. The release properties of the depot systems were much improved over monolithic CA/FA fibers, which exhibited a significant burst release and also considerable tailing-off at the end of the release experiment. Here we thus demonstrate the concept of using modified tri-axial electrospinning to design and develop new types of heterogeneous nanoscale biomaterials.

    Full Text Available Abstract Background Mainly dependent on hormone-sensitive lipase, lipolysis is differently impaired between fat depots in human obesity. Perilipin A expression is a critical element in adipocyte lipolysis. The present study aimed at comparing expression and subcellular distribution of perilipin and hormone-sensitive lipase in two abdominal adipose tissues of lean and obese women. We examined whether regional differences in perilipin expression contribute to impaired lipolytic rates. Methods Abdominal subcutaneous and omental adipose tissues were obtained from six lean and ten obese women. We measured total protein content and relative distribution of hormone-sensitive lipase and perilipin proteins between lipid and non-lipid fractions in tissue homogenates. Hormone-sensitive lipase and perilipin mRNA levels, adipocyte size, basal (non-stimulated and noradrenaline-stimulated lipolysis in isolated adipocytes were determined. Results Adipocytes were significantly larger in the obese versus the lean women and in subcutaneous versus omental fat. Expressed as a function of cell number, basal lipolysis and noradrenaline responsiveness were higher in subcutaneous versus omental adipocytes from the obese women (P Conclusion In both fat depots, a reduced perilipin protein expression was observed in women obesity. Perilipin protein level may contribute to differences in basal lipolysis and in adipocyte size between fat depots and may regulate lipid accumulation in adipocytes. Differences in hormone-sensitive lipase subcellular distribution were reported between fat depots in the obese women.

    Deseret Chemical Depot is one of the US Army`s storage facilities for its stockpile of chemical weapon agents. Congress has directed the Department of Defense to eliminate the aging stockpiles, which have existed since the end of World War II, and the US Army is destroying these lethal chemical munitions. Although the danger is slight, accurate predictions of the wind field in the valley are necessary for dispersion calculations in the event of an accident involving toxic chemicals at the depot. There are several small communities in Rush and Tooele valleys, including the town of Tooele, and Salt Lake City is located 65 km to the Northeast of Deseret Chemical Depot South area, at 1,300 m MSL and beyond the Oquirrh Mountains. The purpose of this report is to carry out three-dimensional numerical simulations of the atmospheric circulations in the region around Deseret Chemical Depot with the Higher Order Turbulence Model for Atmospheric Circulations (HOTMAC) and to evaluate the performance of the model. The code had been modified to assimilate local meteorological observations through the use of Newtonian nudging. The nudging scheme takes advantage of the extensive network of local observations in the valley.

    Diabetes mellitus (DM) is a metabolic disorder due to irregularities in glucose metabolism, as a result of insulin disregulation. Chronic DM (Type 1) is treated by daily insulin injections by subcutaneous route. Daily injections cause serious patient non-compliance and medication non-adherence. Insulin Depots (ID) are parenteral formulations designed to release the insulin over a specified period of time, to control the plasma blood glucose level for intended duration. Physiologically, pancreas produces and secretes insulin in basal and pulsatile mode into the blood. Delivery systems mimicking basal release profiles are known as open-loop systems and current marketed products are open-loop systems. Future trend in open-loop systems is to reduce the number of injections per week by enhancing duration of action, by modifying the depot properties. The next generation technologies are closed-loop systems that mimic the pulsatile mode of delivery by pancreas. In closed-loop systems insulin will be released in response to plasma glucose. This review focuses on future trend in open-loop systems; by understanding (a) the secretion of insulin from pancreas, (b) the insulin regulation normal and in DM, (c) insulin depots and (d) the recent progress in open-loop depot technology particularly with respect to nanosystems.

    Tissue engineering, the application of stem and progenitor cells in combination with an engineered extracellular matrix, is a promising strategy for bone regeneration. However, its success is limited by the lack of vascularization after implantation. The concept of in situ tissue engineering envisages the recruitment of cells necessary for tissue regeneration from the host environment foregoing ex vivo cell seeding of the scaffold. In this study, we developed a novel scaffold system for enhanced cell attraction, which is based on biomimetic mineralized collagen scaffolds equipped with a central biopolymer depot loaded with chemotactic agents. In humid milieu, as after implantation, the signaling factors are expected to slowly diffuse out of the central depot forming a gradient that stimulates directed cell migration toward the scaffold center. Heparin, hyaluronic acid, and alginate have been shown to be capable of depot formation. By using vascular endothelial growth factor (VEGF) as model factor, it was demonstrated that the release kinetics can be adjusted by varying the depot composition. While alginate and hyaluronic acid are able to reduce the initial burst and prolong the release of VEGF, the addition of heparin led to a much stronger retention that resulted in an almost linear release over 28 days. The biological activity of released VEGF was proven for all variants using an endothelial cell proliferation assay. Furthermore, migration experiments with endothelial cells revealed a relationship between the degree of VEGF retention and migration distance: cells invaded deepest in scaffolds containing a heparin-based depot indicating that the formation of a steep gradient is crucial for cell attraction. In conclusion, this novel in situ tissue engineering approach, specifically designed to recruit and accommodate endogenous cells upon implantation, appeared highly promising to stimulate cell invasion, which in turn would promote vascularization and finally new

    Heat treatments (HT) and the induction of heat shock proteins (HSPs) improve whole body and skeletal muscle insulin sensitivity while decreasing white adipose tissue (WAT) mass. However, HSPs in WAT have been understudied. The purpose of the present study was to examine patterns of HSP expression in WAT depots, and to examine the effects of a single in vivo HT on WAT metabolism. Male Wistar rats received HT (41°C, 20 min) or sham treatment (37°C), and 24 h later subcutaneous, epididymal, and retroperitoneal WAT depots (SCAT, eWAT, and rpWAT, respectively) were removed for ex vivo experiments and Western blotting. SCAT, eWAT, and rpWAT from a subset of rats were also cultured separately and received a single in vitro HT or sham treatment. HSP72 and HSP25 expression was greatest in more metabolically active WAT depots (i.e., eWAT and rpWAT) compared with the SCAT. Following HT, HSP72 increased in all depots with the greatest induction occurring in the SCAT. In addition, HSP25 increased in the rpWAT and eWAT, while HSP60 increased in the rpWAT only in vivo. Free fatty acid (FFA) release from WAT explants was increased following HT in the rpWAT only, and fatty acid reesterification was decreased in the rpWAT but increased in the SCAT following HT. HT increased insulin responsiveness in eWAT, but not in SCAT or rpWAT. Differences in HSP expression and induction patterns following HT further support the growing body of literature differentiating distinct WAT depots in health and disease.

    Ultrasonography was used as a noninvasive method for quantitative estimation of the subcutaneous and abdominal adipose tissue depots in dairy cattle. The prediction model was created and validated with a total of 29 German Holstein cows; 6 were in early lactation (≤100 d in milk [DIM]) and 16 were in advanced lactation (101 to 292 DIM). Seven cows were nonpregnant and nonlactating and had been off milk for 350 to 450 d. Transcutaneous assessment of the thickness of subcutaneous and retroperitoneal adipose tissue was done at 16 sites on the body surface of all cows. After completion of the ultrasonographic measurements, the cows were slaughtered and the adipose depots were separately weighed. A stepwise multivariate regression analysis of the ultrasonographic variables was performed to estimate the slaughter weights of the different fat depots. Slaughter weights of the fat depots ranged from 5.0 to 43.0 kg for subcutaneous adipose tissue (SCAT), from 13.7 to 98.8 kg for abdominal adipose tissue (AAT), from 3.4 to 30.3 kg for retroperitoneal adipose tissue (RPAT), from 5.2 to 39.6 kg for omental adipose tissue (OMAT), and from 4.0 to 35.8 kg for mesenteric adipose tissue (MAT). The relationship between calculated amount of fat and slaughter weight of fat had coefficients of determination () and root mean square errors (kg) of 0.88 and 3.4, respectively, for SCAT; 0.94 and 6.1, respectively, for AAT; 0.94 and 1.7, respectively, for RPAT; 0.83 and 3.2, respectively, for OMAT; and 0.95 and 1.6, respectively, for MAT. The accuracy of ultrasonographic measurement of the different fat depots appears sufficient for the quantitative assessment of internal and subcutaneous fat stores in cows. This method is noninvasive and therefore allows safe and repeated monitoring of the amount of stored fat in different adipose tissue depots of German Holsteins cows.

    Treated sewage sludge is commonly used in agriculture as fertilizer. It is, therefore, necessary to determine possible detrimental influences of sludge application on soil contamination and accumulation of contaminants in tissues of terrestrial animals, which in the long run could also have undesirable effects on humans. With that aim, the study was performed using earthworm Eisenia fetida as test organism and semi-solid depot sludge from a wastewater treatment plant as exposure media. The concentrations of 26 metals/metalloids were determined in depot sludge, and their bioaccumulation was estimated in whole tissue of E. fetida, and for the first time in the soluble tissue fraction, which represents metal fraction available for metabolic requirements and toxic effects. Obtained results have revealed acceptable levels of several elements (Cd, Cr, Cu, Ni, Pb, Zn) in depot sludge, when compared to currently valid regulations, and only moderate accumulation of some elements (e.g. As, Ba, Cd, Co, Fe, Tl, V, and Zn) in earthworms, as a consequence of exposure to depot sludge. However, a concentration increase after exposure to depot sludge was observed in E. fetida for several elements (Cd, Mo, and Zn), which were present in lower concentrations in the exposure mixtures than in soil. Contrary, a concentration decrease was observed for Cs, Mn, and Rb, although they were present in higher concentrations in depot sludge than in soil. It was an indication of disturbance in metal homeostasis in earthworms, possibly caused by exposure to complex mixture of contaminants present in depot sludge. The cumulative effect of exposure to a number of various contaminants (inorganic, organic, microbiological and pharmaceutical), even if each of them was not present in very high concentrations, could have caused distress in earthworms exposed to depot sludge.

    Here, a click-cross-linked small intestine submucosa (SIS) drug depot is described for the treatment of rheumatoid arthritis (RA). To the best of the knowledge, there have been no studies related to the intra-articular injection of methotrexate (Met)-loaded click-cross-linkable SIS (Met-loaded Cx-SIS) for RA treatment. As the key objective of this work, injectable formulations of tetrazine-modified SIS (TE-SIS) and transcyclooctene-modified SIS (TC-SIS) are employed as drug depots. Within a few seconds, the simple mixing of equal amounts of TE-SIS and TC-SIS suspensions forms a gelatinous click-cross-linked SIS (Cx-SIS) drug depot in vitro and in vivo. The formed Cx-SIS depot is maintained in the articular joint over an extended period, while SIS alone rapidly disappears. Injectable formulations of Met-loaded Cx-SIS and Met-loaded SIS are prepared and then injected into articular joints to form drug depots. Compared to animals treated with Met-loaded SIS, RA animals treated with Met-loaded Cx-SIS show effective RA repair, as well as extensive regeneration of chondrocytes and glycosaminoglycan deposits. Collectively, these results indicate that the Met-loaded Cx-SIS depot is successfully formed after intra-articular injection of click-cross-linkable SIS, and that this formulation induces long-lasting Met release and allows Met to act effectively in the articular joint, resulting in RA repair.

    Objective To compare bone mineral density (BMD) between users of intramuscular depot medroxyprogesterone acetate(DMPA) and nonhormonal control subjects. Methods The study included 68 women aged between 25 and 40 years using depot medroxyprogesterone acetate for 24 months and 59 women aged between 25 and 40 years using nonhormonal contraception as control subjects. BMD of the lumbar spine and femoral neck were obtained using dual energy X-ray absorptiometry. Results At 24 months of treatment, as compared with baseline, the mean BMD in lumbar spine and femoral neck was decreased by 5.5% and 5.9%, respectively. Lumbar spine and femoral neck BMD in women who used DMPA were significantly decreased compared with the subjects in nonuser (P<0.001). Conclusion These results show BMD declined during using DMPA in women aged 25 -40 years old.

    Port not only function as connections between marine and land transportation but also as core business areas. In a port terminal, available space is limited, but the influx of container is growing. The off-dock depot is one of the key supply chain players that hold empty containers in the inventory. Therefore, this paper aims to identify the main factors of bottlenecks or congestion that hinder the rapid movement of empty containers from the off-dock depot to the customers. Thirty interviews were conducted with individuals who are key players in the container supply chain. The data were analyzed using Atlas.ti software and the analytic hierarchy process to rank the priority factors of bottlenecks. Findings show that several pertinent factors act as barriers to the key players in the container movement in the day-to-day operations. In future studies, strategies to overcome fragmentation in the container supply chain and logistics must be determined.

  17. Optimizing the Shunting Schedule of Electric Multiple Units Depot Using an Enhanced Particle Swarm Optimization Algorithm

    2016-01-01

    The shunting schedule of electric multiple units depot (SSED) is one of the essential plans for high-speed train maintenance activities. This paper presents a 0-1 programming model to address the problem of determining an optimal SSED through automatic computing. The objective of the model is to minimize the number of shunting movements and the constraints include track occupation conflicts, shunting routes conflicts, time durations of maintenance processes, and shunting running time. An enhanced particle swarm optimization (EPSO) algorithm is proposed to solve the optimization problem. Finally, an empirical study from Shanghai South EMU Depot is carried out to illustrate the model and EPSO algorithm. The optimization results indicate that the proposed method is valid for the SSED problem and that the EPSO algorithm outperforms the traditional PSO algorithm on the aspect of optimality.

    Marcadenti, Aline; de Abreu-Silva, Erlon Oliveira

    2015-11-01

    Increased adiposity has been associated to worse metabolic profile, cardiovascular disease, and mortality. There are two main adipose tissue depots in the body, subcutaneous and visceral adipose tissue, which differ in anatomical location. A large body of evidence has shown the metabolic activity of adipose tissue; lipectomy and/or liposuction therefore appear to be alternatives for improving metabolic profile through rapid loss of adipose tissue. However, surgical removal of adipose tissue may be detrimental for metabolism, because subcutaneous adipose tissue has not been associated to metabolic disorders such as insulin resistance and type 2 diabetes mellitus. In addition, animal studies have shown a compensatory growth of adipose tissue in response to lipectomy. This review summarizes the implications of obesity-induced metabolic dysfunction, its relationship with the different adipose tissue depots, and the effects of lipectomy on cardiometabolic risk factors.

    2016-11-01

    Increased plasma plasminogen activator inhibitor-1 (PAI-1) level is considered a mechanistic pathway through which obesity contributes to increased cardiovascular disease risk. Abdominal adipose tissue specifically, is a major PAI-1 source with visceral adipose tissue (VAT), an ectopic fat depot, generally considered to produce more PAI-1 than subcutaneous adipose tissue. However, this does not necessarily lead to increased plasma PAI-1 levels. This review provides an overview of studies investigating the association between body fat distribution and plasma PAI-1 levels. It discusses factors that influence this relationship and also considers the contribution of other tissue to plasma PAI-1 levels, placing the relative contribution of adipose tissue into perspective. In conclusion, the relationship between VAT and plasma PAI-1 levels is not fixed but can be modulated by a number of factors such as the size of the subcutaneous adipose tissue depot, ethnicity, possibly genetics and other obesity-related metabolic abnormalities.

    2001-01-01

    It is well known that the most prominent characteristic of emergency systems is the limit of time. A scheme must be made in much shorter time, and the retrieval vehicle should be able to reach the emergency site in the earliest time according to the proposed scheme so that the emergency event is dealt with as early as possible. This paper deals with multi-depot problems in two cases: (1) When the duration or time needed by the retrieval vehicle arriving at the emergency site from each depot is a non-negative real number, a single-objective (or min-max) and a two-phase problems on the earliest-emergency-activity-start-time (EEAST) are considered. (2) When the duration is regarded as an interval number, we consider the problem of finding an optimal scheme meeting a given deadline t with maximum possibility (or truth value).

    Several treatments have been described for the management of patients with herpes zoster ophthalmicus (HZO). However, the progress of these patients is usually slow, and many of them develop postherpetic neuritis (PHN). In the present paper, three clinical cases are presented, in which a significant symptomatic improvement was obtained by using a preauricular injection of a mixture of betamethasone depot combined with acyclovir. PHN did not develop in any of them. The preauricular injection of betamethasone depot and acyclovir could be a good alternative for the management of HZO.

    Full Text Available Adipocyte differentiation and its impact on restriction or expansion of particular adipose tissue depots has physiological and pathophysiological significance in view of the different functions of these depots. Brown or beige fat [BAT] expansion can enhance thermogenesis, lipid oxidation, insulin sensitivity and glucose tolerance; conversely expanded visceral fat [VAT] is associated with insulin resistance, low grade inflammation, dyslipidaemia and cardiometabolic risk. The largest depot, subcutaneous white fat [WAT], has important beneficial characteristics including storage of lipid out of harms way and secretion of adipokines, especially leptin and adiponectin, with positive metabolic effects including lipid oxidation, energy utilisation, enhanced insulin action and an anti-inflammatory role. The absence of these functions in lipodystrophies leads to major metabolic disturbances. An ability to expand WAT adipocyte differentiation would seem an important defence mechanism against the detrimental effects of energy excess and limit harmful accumulation of lipid in ectopic sites, such as liver and muscle.Adipocyte differentiation involves a transcriptional cascade with PPARg being most important in WAT but less so in VAT, with increased angiogenesis also critical. The transcription factor, Islet1, is fairly specific to VAT and in vitro inhibits adipocyte differentiation. The physiological importance of Islet1 requires further study. Basic control of differentiation is similar in BAT but important differences include the effect of PGC-1a on mitochondrial biosynthesis and upregulation of UCP1; also PRDM16 plays a pivotal role in expression of the BAT phenotype.Modulation of the capacity or function of these different adipose tissue depots, by altering adipocyte differentiation or other means, holds promise for interventions that can be helpful in human disease, particularly cardiometabolic disorders associated with the world wide explosion of

    Full Text Available Depot medroxyprogesterone acetate (DMPA is a commonly used form of contraception, with noncontraceptive benefits for the user. The mode of action is through the suppression of ovulation. It leads to hypoestrogenism which causes dryness of the vagina and dyspareunia. We present in this paper a patient that was very symptomatic with regard to vaginal atrophic changes determined by vaginal cytology. This side effect may become increasingly more common as we see more long-term use of DMPA.

    Full Text Available Abstract Background In South Africa, where health care resources are limited, it is important to ensure that drugs provision and use is rational. The Essential Drug List includes depot medroxyprogesterone acetate (DMPA and norethisterone oenanthate (NET-EN as injectable progestagen-only contraceptives (IPCs, and both products are extensively used. Objectives and Methods Utilisation patterns of the injectable contraceptive products DMPA and NET-EN are compared in the context of current knowledge of the safety and efficacy of these agents. Utilisation patterns were analysed by means of a Pareto (ABC analysis of IPCs issued from 4 South African provincial pharmaceutical depots over 3 financial years. A case study from rural KwaZulu-Natal, South Africa, is used to examine utilisation patterns and self-reported side effects experienced by 187 women using IPCs. Results IPCs accounted for a substantial share of total state expenditure on drugs. While more DMPA than NET-EN was issued, NET-EN distribution from 2 depots increased over the 3-year period. Since DMPA was cheaper, if all NET-EN clients in the 1999/2000 financial year (annualised had used DMPA, the 4 depots could have saved 4.95 million South African Rands on product acquisition costs alone. The KZN case study showed slightly more NET-EN (54% than DMPA (46% use; no significant differences in self-reported side effects; and that younger women were more likely to use NET-EN than DMPA (p = 0.0001. Conclusions Providing IPCs on the basis of age is not appropriate or cost effective. Rational use of these products should include consideration of the cost of prescribing one over another.

    Full Text Available Pituitary suppression by depot GnRH agonist may be excessive for ovarian stimulation. This study compares the efficacy of a single half-dose depot triptorelin and reduced-dose daily buserelin in a long protocol ICSI/ET. METHODS: A total of 182 patients were randomized into two groups using sealed envelopes. Pituitary desensitization was obtained in group 1 (91 patients with half-dose (1.87 mg depot triptorelin in the mid-luteal phase of their menstrual cycle, and in group 2 (91 patients with standard daily dose (0.5 mg buserelin, which was then reduced to 0.25 mg at the start of human menopausal gonadotropin (HMG stimulation. RESULTS: No significant differences were found among those who received HCG in terms of clinical pregnancy rate (34.4% in both groups, implantation rate (14.8% in group 1 versus 11.1% in group 2, fertilization rate (93.3 versus 95.6%, poor response rate (11.1 versus 6.7%, and miscarriage rate (11.1 versus 7.8%. No significant differences were seen in number of HMG ampoules used, follicles at HCG administration, and oocytes retrieved. The number of days of stimulation was significantly reduced in group 2 (11.2 +/- 1.8 in group 1 versus 10.6 +/- 1.9, p = 0.030. CONCLUSION: A half-dose of depot triptorelin can be successfully used in ovarian stimulation instead of reduced-dose daily buserelin, with more patient comfort and reduced stress and cost of injections.

    Full Text Available An interdisciplinary environmental assessment team from the Howard University Environmental Justice Partnership (HUEJP conducted a site visit and assessment of the Defense Depot of Memphis, Tennessee in February of 2000. This depot was built in the late 1940’s for storage of numerous chemicals and munitions. As the years progressed, many Memphis citizens have grown to believe that the activities and chemical stockpile located at this site have negatively affected the health environment of their residents. There is anecdotal evidence and documentation of numerous cancers and other illnesses in those local territories, and specifically, at the Memphis Depot site. Currently, this depot is closed and in remediation by the local government. Particularly, citizens of the Rozelle community have started a campaign to investigate any signs of exposure pathways to noted health risks. The HUEJP was contacted and asked to investigate the community concerns. Obliging to the request, we aimed to sample at three drainage sites and a residential site, talk to local citizens, and gain any additional information that would be helpful in relieving anxiety in the Rozelle community. Soil, sediment, and water samples were collected and analyzed for total organic carbon, inorganic anions, and heavy metals. These data show that for the four sites sampled, the highest concentrations of organic compounds and heavy metals were located either within a residential area or in an area with a direct transport pathway to the community. Atomic absorption analysis revealed detectable amounts of cadmium, lead and chromium metals at all sites with direct transport pathways into the residential community, with chromium concentrations being far in excess of the EPA standard limits.

    Long-acting somatostatin analogs are one of the main classes of medical therapy used for acromegaly and most patients require ongoing treatment. Few studies have evaluated the long-term efficacy and safety of lanreotide depot beyond 2 years. The goal of this study was to provide a long-term longitudinal assessment of efficacy and safety of lanreotide depot in lanreotide responders compared to a surgically cured control group. In this retrospective longitudinal case-control study, patients with acromegaly receiving lanreotide depot monotherapy continuously for at least 24 months (N = 24) and surgically cured patients (N = 39) were compared. Serum IGF-1, pituitary MRIs, lanreotide dose, co-morbidities and adverse effects were assessed longitudinally. In the lanreotide group, IGF-1 remained normal and unchanged over 6 years; comparable to the surgery only group. There was no difference in prevalence of normal IGF-1 between the lanreotide and surgery only groups at 6 months (100 vs. 97 %), 6 years (89 vs. 90 %) and at last follow-up (96 vs. 92 %). Tumor size remained stable (79 %) or decreased (21 %) in the lanreotide group. In the surgery only group, tumor size remained unchanged in all patients. Hemoglobin A1C did not differ between lanreotide and surgery only groups (baseline 5.8 vs. 6.1 %; last follow-up 6.0 vs. 5.7 %). Two (8 %) of the lanreotide and none of the surgery only group developed new diabetes mellitus. Lanreotide depot maintains normalization of IGF-1 in 89 % of responders after 6 years, comparable to surgically cured controls, and controlled tumor size in all without significant adverse effects.

    Radiculopathy, a painful neuroinflammation that can accompany intervertebral disc herniation, is associated with locally increased levels of the pro-inflammatory cytokine tumor necrosis factor alpha (TNFα). Systemic administration of TNF antagonists for radiculopathy in the clinic has shown mixed results, and there is growing interest in the local delivery of anti-inflammatory drugs to treat this pathology as well as similar inflammatory events of peripheral nerve injury. Curcumin, a known antagonist of TNFα in multiple cell types and tissues, was chemically modified and conjugated to a thermally responsive elastin-like polypeptide (ELP) to create an injectable depot for sustained, local delivery of curcumin to treat neuroinflammation. ELPs are biopolymers capable of thermally-triggered in situ depot formation that have been successfully employed as drug carriers and biomaterials in several applications. ELP-curcumin conjugates were shown to display high drug loading, rapidly release curcumin in vitro via degradable carbamate bonds, and retain in vitro bioactivity against TNFα-induced cytotoxicity and monocyte activation with IC50 only two-fold higher than curcumin. When injected proximal to the sciatic nerve in mice via intramuscular (i.m.) injection, ELP-curcumin conjugates underwent a thermally triggered soluble-insoluble phase transition, leading to in situ formation of a depot that released curcumin over 4days post-injection and decreased plasma AUC 7-fold. © 2013.

    Full Text Available La Hemiatrofia Facial Progresiva, comúnmente conocida como Síndrome de Parry-Romberg (SPR, es una enfermedad idiopática, progresiva y autolimitada, que afecta de manera variable y unilateral en la mayor parte de los casos a la piel, tejido celular subcutáneo, grasa, músculo y, con menor frecuencia, a las estructuras osteocartilaginosas faciales produciendo asimetría craneofacial. En el manejo quirúrgico del SPR en estadios medios y moderados se ha empleado desde hace años la infiltración de injertos grasos; sin embargo, se trataba de una técnica de resultados impredecibles dada su tendencia a la reabsorción. Gracias a los avances en biología molecular se ampliaron nuestros horizontes ante la posibilidad de usar las células madre propias del tejido adiposo con el fin de asegurar la viabilidad y permanencia del implante graso a través del tiempo. En este trabajo presentamos nuestra experiencia de los últimos 3 años en el tratamiento del SPR en pacientes pediátricos, consiguiendo la restauración de la volumetría y la simetría faciales mediante el uso de injertos grasos enriquecidos con células madre extraídas del propio paciente y en el mismo acto quirúrgico.

    Full Text Available Background/Aim. There is a high rate of schizophrenic patients who do not adhere to their prescribed therapy, despite the implementation of antipsychotic long-acting injections and the introduction of atypical antipsychotics. The aim of this study was to investigate the differences in sociodemographic, clinical and medication adherence variables between the two groups of schizophrenic patients on maintenance therapy with depot antipsychotic fluphenazine decanoate and oral antipsychotics only as well as a correlation between the medication adherence and other examined variables. Methods. A total of 56 patients of both genders, aged < 60 years, with the diagnosis of schizophrenia (F20 (ICD-10, 1992 clinically stable for at least 6 months were introduced in this cross-sectional study. The patients from the depot group (n = 19 were on classical depot antipsychotic fluphenazine decanoate administering intramuscularly every 4 weeks (with or without oral antipsychotic augmentation and the patients from the oral group (n = 37 were on oral therapy alone with classical or atypical antipsychotics, either as monotherapy or combined. The Positive and Negative Syndrome Scale (PANSS was used to assess symptom severity. Item G12 of the PANSS was used to assess insight into the illness. The patients completed the Medical Adherence Rating Scale (MARS was used to assess adherence to the therapy. A higher MARS score indicates behavior [Medical Adherence Questionnaire (MAQ subscale] and attitudes toward medication [Drug Attitude Inventory (DAI subscale] that are more consistent with treatment adherence. The exclusion criteria were determined. The Pearson's χ2 test was used to compare categorical variables, Student's t-test to compare continuous variables and Pearson's correlation to test the correlation significance; p = 0.05. Results. Significant betweengroup differences in age, illness duration, chlorpromazine equivalents, PANSS score and DAI subscore were found

    Growth hormone receptor-null (GHR(-/-)) mice are dwarf, insulin sensitive, and long-lived in spite of increased adiposity. However, their adiposity is not uniform, with select white adipose tissue (WAT) depots enlarged. To study WAT depot-specific effects on insulin sensitivity and life span, we analyzed individual WAT depots of 12- and 24-month-old GHR(-) (/-) and wild-type (WT) mice, as well as their plasma levels of selected hormones. Adipocyte sizes and plasma insulin, leptin, and adiponectin levels decreased with age in both GHR(-) (/-) and WT mice. Two-dimensional gel electrophoresis proteomes of WAT depots were similar among groups, but several proteins involved in endocytosis and/or cytoskeletal organization (Ehd2, S100A10, actin), anticoagulation (S100A10, annexin A5), and age-related conditions (alpha2-macroglobulin, apolipoprotein A-I, transthyretin) showed significant differences between genotypes. Because Ehd2 may regulate endocytosis of Glut4, we measured Glut4 levels in the WAT depots of GHR(-) (/-) and WT mice. Inguinal WAT of 12-month-old GHR(-) (/-) mice displayed lower levels of Glut4 than WT. Overall, the protein changes detected in this study offer new insights into possible mechanisms contributing to enhanced insulin sensitivity and extended life span in GHR(-) (/-) mice.

    Full Text Available This paper suggests spatial multi-criteria model in order to assist decision makers in the selection of sites which are suitable for ammunition depots (AD. They represent military facilities which have more criteria that need to be matched than civil structures. The proposed model is based on combined use of Geographic information systems (GIS and multi-criteria techniques. The model application is presented in the case study of Carpathian region, the Eastern part of Serbia. The model deals with nine restrictions and six evaluation criteria. Decision Making Trial and Evaluation Laboratory—Analytic Network Process (DEMATEL-ANP multi-criteria techniques are used to determine weight coefficients of evaluation criteria. Along with the above mentioned methods, this paper introduces a new technique for the multi-criteria decision making—MAIRCA (MultiAttributive Ideal-Real Comparative Analysis method. The MAIRCA method is used for the ranking and selection of suitable locations. The results have shown that 45 km2 of the Carpathian region is very suitable for ammunition depot construction. The MAIRCA method chose location L1 as the most appropriate. Sensitivity analysis shows that the model is capable of identifying a suitable ammunition depot location. This approach can be helpful in determining suitable ammunition depot locations in other regions with similar geographic conditions and can also be successfully used for the suitability assessment of existing ammunition depots.

    Depot-medroxyprogesterone acetate is a commonly used injectable contraceptive that has been associated with an increased risk of HIV acquisition. This study compares effects of depot-medroxyprogesterone acetate on immune parameters from several upper reproductive tract compartments relevant to HIV-1 susceptibility in repetitive samples from 15 depot-medroxyprogesterone acetate users and 27 women not on hormonal contraceptives. Compared with samples from unexposed women in the mid-luteal phase, depot-medroxyprogesterone acetate use was associated with: increased endocervical concentrations of MCP1 and IFNalpha2; decreased endocervical concentrations of IL1beta and IL6; increased proportions of endometrial CD4+ and CD8+ cells expressing the activation marker HLADR; increased density of endometrial macrophages; and decreased density of endometrial regulatory T cells. Unlike previous reports with samples from the vagina, we did not observe increased expression of the HIV co-receptor CCR5 on CD4+ T cells in the endocervix or endometrium. Our results indicate important differences in anatomic compartments regarding mechanisms by which depot-medroxyprogesterone acetate could be associated with increased risk of HIV acquisition, including increased recruitment of macrophages to the endometrium, decreased levels of pro-inflammatory cytokines in the endocervix possibly leading to enhanced susceptibility to viral infection, and activation of endometrial T cells.

    Chronic hepatitis C (CHC) is associated with lipid-related changes and insulin resistance; the latter predicts response to antiviral therapy, liver disease progression and the risk of diabetes. We sought to determine whether insulin sensitivity improves following CHC viral eradication after antiviral therapy and whether this is accompanied by changes in fat depots or adipokine levels. We compared 8 normoglycaemic men with CHC (genotype 1 or 3) before and at least 6 months post viral eradication and 15 hepatitis C antibody negative controls using an intravenous glucose tolerance test and two-step hyperinsulinaemic-euglycaemic clamp with [6,6-(2) H2 ] glucose to assess peripheral and hepatic insulin sensitivity. Magnetic resonance imaging and spectroscopy quantified abdominal fat compartments, liver and intramyocellular lipid. Peripheral insulin sensitivity improved (glucose infusion rate during high-dose insulin increased from 10.1 ± 1.6 to 12 ± 2.1 mg/kg/min/, P = 0.025), with no change in hepatic insulin response following successful viral eradication, without any accompanying change in muscle, liver or abdominal fat depots. There was corresponding improvement in incremental glycaemic response to intravenous glucose (pretreatment: 62.1 ± 8.3 vs post-treatment: 56.1 ± 8.5 mm, P = 0.008). Insulin sensitivity after viral clearance was comparable to matched controls without CHC. Post therapy, liver enzyme levels decreased but, interestingly, levels of glucagon, fatty acid-binding protein and lipocalin-2 remained elevated. Eradication of the hepatitis C virus improves insulin sensitivity without alteration in fat depots, adipokine or glucagon levels, consistent with a direct link of the virus with insulin resistance. © 2013 John Wiley & Sons Ltd.

    According to the Developmental Origin of Health and Disease (DOHaD) concept, alterations of nutrient supply in the fetus or neonate result in long-term programming of individual body weight (BW) setpoint. In particular, maternal obesity, excessive nutrition, and accelerated growth in neonates have been shown to sensitize offspring to obesity. The white adipose tissue may represent a prime target of metabolic programming induced by maternal obesity. In order to unravel the underlying mechanisms, we have developed a rat model of maternal obesity using a high-fat (HF) diet (containing 60% lipids) before and during gestation and lactation. At birth, newborns from obese dams (called HF) were normotrophs. However, HF neonates exhibited a rapid weight gain during lactation, a key period of adipose tissue development in rodents. In males, increased BW at weaning (+30%) persists until 3months of age. Nine-month-old HF male offspring was normoglycemic but showed mild glucose intolerance, hyperinsulinemia, and hypercorticosteronemia. Despite no difference in BW and energy intake, HF adult male offspring was predisposed to fat accumulation showing increased visceral (gonadal and perirenal) depots weights and hyperleptinemia. However, only perirenal adipose tissue depot exhibited marked adipocyte hypertrophy and hyperplasia with elevated lipogenic (i.e. sterol-regulated element binding protein 1 (Srebp1), fatty acid synthase (Fas), and leptin) and diminished adipogenic (i.e. peroxisome proliferator-activated receptor gamma (Pparγ), 11β-hydroxysteroid dehydrogenase type 1 (11β-Hds1)) mRNA levels. By contrast, very few metabolic variations were observed in HF female offspring. Thus, maternal obesity and accelerated growth during lactation program offspring for higher adiposity via transcriptional alterations of visceral adipose tissue in a depot- and sex-specific manner. © 2016 Society for Endocrinology.

    Full Text Available In this study, the assignment and routing problem of one of Istanbul’s winter maintenance activities, salt pouring, was scrutinized. The starting point of the study considers the high cost of winter maintenance work, a shrinking assigned budget, high numbers of vehicles and streets to service that the increase in difficulty to solve the problem due to their high numbers. In this respect, the problem was modeled as multi depot k-Chinese postman problem, a type of arc routing problem. This mathematical model was solved by genetic algorithm. For comparison, the current solution, Clarke and Wright Algorithm and Sweep Algorithm were used.

    The Dot Enumeration Perceptual Organization Task (DEPOT) evaluates the validity of 2 specific competing cognitive models of early input dysfunction in schizophrenic individuals: a primary Stage 1, sensory store, perceptual organization deficit vs. a Stage 2, short-term visual memory (STVM) deficit. DEPOT was also designed to assess the hypothesis that schizophrenic individuals tend to perform poorly on all cognitive tasks. In DEPOT both number and form judgments are made about the same dot patterns. A response delay manipulation assesses the persistence and operation of STVM. The study included 41 psychotic inpatients (8 with acute and 16 with chronic schizophrenia and 7 with bipolar and 10 with nonbipolar affective disorder) and 38 controls (22 college students and 16 hospital personnel). Although the pattern of results was consistent with neither the Stage 1 deficit nor the general deficit hypotheses, a Stage 2, STVM deficit hypothesis could account parsimoniously for the data.

  9. Humans and Mice Display Opposing Patterns of “Browning” Gene Expression in Visceral and Subcutaneous White Adipose Tissue Depots

    2017-05-01

    Full Text Available Visceral adiposity is much more strongly associated with cardiometabolic disease in humans than subcutaneous adiposity. Browning, the appearance of brown-like adipocytes in the white adipose tissue (WAT, has been shown to protect mice against metabolic dysfunction, suggesting the possibility of new therapeutic approaches to treat obesity and type 2 diabetes. In mice, subcutaneous WAT depots express higher levels of browning genes when compared with visceral WAT, further suggesting that differences in WAT browning could contribute to the differences in the pathogenicity of the two depots. However, the expression of browning genes in different WAT depots of human has not been characterized. Here, it is shown that the expression of browning genes is higher in visceral than in subcutaneous WAT in humans, a pattern that is opposite to what is observed in mice. These results suggest that caution should be applied in extrapolating the results of murine browning gene expression studies to human pathophysiology.

    Full Text Available It is well established that the metabolic risk factors of obesity and its comorbidities are more attributed to adipose tissue distribution rather than total adipose mass. Since emerging evidence suggests that epigenetic regulation plays an important role in the aetiology of obesity, we conducted a genome-wide methylation analysis on eight different adipose depots of three pig breeds living within comparable environments but displaying distinct fat level using methylated DNA immunoprecipitation sequencing. We aimed to investigate the systematic association between anatomical location-specific DNA methylation status of different adipose depots and obesity-related phenotypes. We show here that compared to subcutaneous adipose tissues which primarily modulate metabolic indicators, visceral adipose tissues and intermuscular adipose tissue, which are the metabolic risk factors of obesity, are primarily associated with impaired inflammatory and immune responses. This study presents epigenetic evidence for functionally relevant methylation differences between different adipose depots.

    Full Text Available Adipose tissue plays a critical role in energy homeostasis and metabolism. There is sparse understanding of the molecular regulation at the protein level of bovine adipose tissues, especially within different fat depots under different nutritional regimes. The objective of this study was to analyze the differences in protein expression between bovine subcutaneous and visceral fat depots in steers fed different diets and to identify the potential regulatory molecular mechanisms of protein expression. Subcutaneous and visceral fat tissues were collected from 16 British-continental steers (15.5 month old fed a high-fat diet (7.1% fat, n=8 or a control diet (2.7% fat, n=8. Protein expression was profiled using label free quantification LC-MS/MS and expression of selected transcripts was evaluated using qRT-PCR. A total of 682 proteins were characterized and quantified with fat depot having more impact on protein expression, altering the level of 51.0% of the detected proteins, whereas diet affected only 5.3%. Functional analysis revealed that energy production and lipid metabolism were among the main functions associated with differentially expressed proteins between fat depots, with visceral fat being more metabolically active than subcutaneous fat as proteins associated with lipid and energy metabolism were upregulated. The expression of several proteins was significantly correlated to subcutaneous fat thickness and adipocyte size, indicating their potential as adiposity markers. A poor correlation (r=0.245 was observed between mRNA and protein levels for 9 genes, indicating that many proteins may be subjected to post-transcriptional regulation. A total of 8 miRNAs were predicted to regulate more than 20% of lipid metabolism proteins differentially expressed between fat depots, suggesting that miRNAs play a role in adipose tissue regulation. Our results show that proteomic changes support the distinct metabolic and physiological characteristics

    Preclinical HIV prevention models use either a single high-dose viral challenge in depot medroxyprogesterone acetate-treated macaques or repeated viral challenges in cycling macaques. We tested the efficacy of an intravaginal tenofovir disoproxil fumarate (TDF) ring in a model combining repeated 30-mg injections of depot medroxyprogesterone acetate every 6 weeks with vaginal viral challenges weekly for 12 weeks. Twelve macaques were randomized to TDF or placebo rings. All placebo macaques became infected after a median of 2 exposures, whereas only 1 TDF macaque became infected at the eighth exposure (P = 0.0012). The TDF ring provides durable protection in a stringent challenge model.

    Full Text Available In this paper, we consider the time-dependent multi-depot vehicle routing problem. The objective is to minimize the total heterogeneous fleet cost assuming that the travel time between locations depends on the departure time. Also, hard time window constraints for the customers and limitation on maximum number of the vehicles in depots must be satisfied. The problem is formulated as a mixed integer programming model. A constructive heuristic procedure is proposed for the problem. Also, the efficiency of the proposed algorithm is evaluated on 180 test problems. The obtained computational results indicate that the procedure is capable to obtain a satisfying solution.

    Endometriosis is an estrogen-dependent chronic inflammatory disorder that requires a life-long management plan. Long-term adherence to treatment is pivotal to ensure an effective clinical management. In this optic, one of the cornerstone of endometriosis medical treatment is represented by progestins. Areas covered: This narrative review examines the clinical efficacy, safety and tolerability of oral and depot progestins used in the treatment of endometriosis. The material included in the current manuscript was obtained with a MEDLINE search through PubMed from inception until February 2017. Expert opinion: Progestins are effective in controlling pain symptoms in the majority of women with endometriosis, and their effect seems not inferior to that achieved with other compounds used to treat the disease, such as gonadotropin-releasing hormone agonist. Available progestins include a broad range of both oral and depot compounds, and represent, in most cases, an inexpensive treatment option. In addition, progestins do not increase significantly thrombotic risk and could be adopted in those women with metabolic or cardiovascular contraindication to estrogen-progestins. The choice between the different available compounds should be tailored for every woman with preference to the most cost-effective treatment, depending on the most complained symptom and disease location.

  15. A Fuzzy Goal Programming for a Multi-Depot Distribution Problem

    2010-10-01

    A fuzzy goal programming model for solving a Multi-Depot Distribution Problem (MDDP) is proposed in this research. This effective proposed model is applied for solving in the first step of Assignment First-Routing Second (AFRS) approach. Practically, a basic transportation model is firstly chosen to solve this kind of problem in the assignment step. After that the Vehicle Routing Problem (VRP) model is used to compute the delivery cost in the routing step. However, in the basic transportation model, only depot to customer relationship is concerned. In addition, the consideration of customer to customer relationship should also be considered since this relationship exists in the routing step. Both considerations of relationships are solved using Preemptive Fuzzy Goal Programming (P-FGP). The first fuzzy goal is set by a total transportation cost and the second fuzzy goal is set by a satisfactory level of the overall independence value. A case study is used for describing the effectiveness of the proposed model. Results from the proposed model are compared with the basic transportation model that has previously been used in this company. The proposed model can reduce the actual delivery cost in the routing step owing to the better result in the assignment step. Defining fuzzy goals by membership functions are more realistic than crisps. Furthermore, flexibility to adjust goals and an acceptable satisfactory level for decision maker can also be increased and the optimal solution can be obtained.

    Naltrexone is an opioid receptor antagonist that blocks the reinforcing effects of opioids and reduces alcohol consumption and craving. It has no abuse potential, mild and transient side effects, and thus appears an ideal pharmacotherapy for opioid dependence. Its effectiveness in alcohol dependence is less evident, but compliance with naltrexone combined with psychosocial support has been repeatedly shown to improve drinking outcomes. Limited compliance with oral naltrexone treatment is a known drawback. Several naltrexone implant and injectable depot formulations are being investigated and provide naltrexone release for at least 1 month. Studies among opioid-dependent patients indicate significant reductions in heroin use, but sample sizes are usually small. In alcohol dependence, two large multicenter trials report alcohol and craving reductions for naltrexone and placebo groups, indicating a significant but moderate effect. The pharmacokinetic profile of the injectable formulation indicates reliable naltrexone release over 1 month at therapeutic levels. Implant formulations releasing naltrexone up to 7 months are reported. Findings on safety and tolerability confirm the generally mild adverse effects described for naltrexone tablets. However, further research on therapeutic levels (i.e., opioid blocking) is warranted. The majority of naltrexone implants lacks approval for regular clinical use and larger longitudinal studies are needed. The available naltrexone depot formulations have the potential to significantly improve medication compliance in opioid and alcohol dependence. In certain circumstances, they may constitute a promising new treatment option. © 2010 Blackwell Publishing Ltd.

    Increasing evidence suggests depot medroxyprogesterone acetate (DMPA) and intravaginal practices may be associated with human immunodeficiency virus (HIV-1) infection risk; however, the mechanisms are not fully understood. This study evaluated the effect of DMPA and intravaginal practices on the genital proteome and microbiome to gain mechanistic insights. Cervicovaginal secretions from 86 Kenyan women, including self-reported DMPA users (n = 23), nonhormonal contraceptive users (n = 63), and women who practice vaginal drying (n = 46), were analyzed using tandem-mass spectrometry. We identified 473 human and 486 bacterial proteins from 18 different genera. Depot medroxyprogesterone acetate use associated with increased hemoglobin and immune activation (HBD, HBB, IL36G), and decreased epithelial repair proteins (TFF3, F11R). Vaginal drying associated with increased hemoglobin and decreased phagocytosis factors (AZU1, MYH9, PLAUR). Injury signatures were exacerbated in DMPA users who also practiced vaginal drying. More diverse (H index: 0.71 vs 0.45; P = .009) bacterial communities containing Gardnerella vaginalis associated with vaginal drying, whereas DMPA showed no significant association with community composition or diversity. These findings provide new insights into the impact of DMPA and vaginal drying on mucosal barriers. Future investigations are needed to confirm their relationship with HIV risk in women.

    Assembling and/or producing integrated knowledge of sequence features continues to be an onerous and redundant task despite a large number of existing resources. We have developed SeqDepot-a novel database that focuses solely on two primary goals: (i) assimilating known primary sequences with predicted feature data and (ii) providing the most simple and straightforward means to procure and readily use this information. Access to >28.5 million sequences and 300 million features is provided through a well-documented and flexible RESTful interface that supports fetching specific data subsets, bulk queries, visualization and searching by MD5 digests or external database identifiers. We have also developed an HTML5/JavaScript web application exemplifying how to interact with SeqDepot and Perl/Python scripts for use with local processing pipelines. Freely available on the web at http://seqdepot.net/. RESTaccess via http://seqdepot.net/api/v1. Database files and scripts maybe downloaded from http://seqdepot.net/download.

    Full Text Available Castration-resistant prostate cancer (CRPC is one of the most complex and unsolved problems in urologic oncology. The somatostatin analogue octreotide depot made in Russia may be used for its treatment. The paper gives the results of a trial of the efficiency and safety of treatment with octreotide depot 30 mg and dexamethasone in 20 patients aged 58 to 89 years with CRPC during continued androgen deprivation therapy. The duration of the trial was 3 months. A response was assessed from the serum levels of prostate-specific antigen (PCA, the time course of changes in general and biochemical blood test values, the degree of pain syndrome, and improvement in quality of life in a patient. A total response in reducing PSA was obtained in 70 % of the patents; overall, the best results were achieved in the group receiving octreotide before chemotherapy with docetaxel. The tolerability of octreotide deport with dexamethasone was good in all cases; no obvious adverse hematological and clinical reactions were noted.

    2017-01-01

    Due to its environmentally sustainable and energy-saving characteristics, railway transportation nowadays plays a fundamental role in delivering passengers and goods. Emerged in the area of transportation planning, the crew (workforce) sizing problem and the crew scheduling problem have been attached great importance by the railway industry and the scientific community. In this paper, we aim to solve the two problems by proposing a novel two-stage optimization approach in the context of the electric multiple units (EMU) depot shunting driver assignment problem. Given a predefined depot shunting schedule, the first stage of the approach focuses on determining an optimal size of shunting drivers. While the second stage is formulated as a bi-objective optimization model, in which we comprehensively consider the objectives of minimizing the total walking distance and maximizing the workload balance. Then we combine the normalized normal constraint method with a modified Pareto filter algorithm to obtain Pareto solutions for the bi-objective optimization problem. Furthermore, we conduct a series of numerical experiments to demonstrate the proposed approach. Based on the computational results, the regression analysis yield a driver size predictor and the sensitivity analysis give some interesting insights that are useful for decision makers.

  1. Relationships between rodent white adipose fat pads and human white adipose fat depots

    2016-04-01

    Full Text Available The objective of this review was to compare and contrast the physiological and metabolic profiles of rodent white adipose fat pads with white adipose fat depots in humans. Human fat distribution and its metabolic consequences have received extensive attention, but much of what has been tested in translational research has relied heavily on rodents. Unfortunately, the validity of using rodent fat pads as a model of human adiposity has received less attention. There is a surprisingly lack of studies demonstrating an analogous relationship between rodent and human adiposity on obesity-related comorbidities. Therefore, we aimed to compare known similarities and disparities in terms of white adipose tissue development and distribution, sexual dimorphism, weight loss, adipokine secretion, and aging. While the literature supports the notion that many similarities exist between rodents and humans, notable differences emerge related to fat deposition and function of white adipose tissue. Thus, further research is warranted to more carefully define the strengths and limitations of rodent white adipose tissue as a model for humans, with a particular emphasis on comparable fat depots, such as mesenteric fat.

  2. The multi-depot electric vehicle location routing problem with time windows

    2018-01-01

    Full Text Available In this paper, the Multi-Depot Electric Vehicle Location Routing Problem with Time Windows (MDVLRP is addressed. This problem is an extension of the MDVLRP, where electric vehicles are used instead of internal combustion engine vehicles. The recent development of this model is explained by the advantages of this technology, such as the diminution of carbon dioxide emissions, and the support that they can provide to the design of the logistic and energy-support structure of electric vehicle fleets. There are many models that extend the classical VRP model to take electric vehicles into consideration, but the multi-depot case for location-routing models has not been worked out yet. Moreover, we consider the availability of two energy supply technologies: the “Plug-in” Conventional Charge technology, and Battery Swapping Stations; options in which the recharging time is a function of the amount of energy to charge and a fixed time, respectively. Three models are proposed: one for each of the technologies mentioned above, and another in which both options are taken in consideration. The models were solved for small scale instances using C++ and Cplex 12.5. The results show that the models can be used to design logistic and energy-support structures, and compare the performance of the different options of energy supply, as well as measure the impact of these decisions on the overall distance traveled or other optimization objectives that could be worked on in the future.

  3. A tabu-search heuristic for solving the multi-depot vehicle scheduling problem

    2014-08-01

    Full Text Available Currently the logistical problems are relying quite significantly on Operational Research in order to achieve greater efficiency in their operations. Among the problems related to the vehicles scheduling in a logistics system, the Multiple Depot Vehicle Scheduling Problem (MDVSP has been addressed in several studies. The MDVSP presupposes the existence of depots that affect the planning of sequences to which travel must be performed. Often, exact methods cannot solve large instances encountered in practice and in order to take them into account, several heuristic approaches are being developed. The aim of this study was thus to solve the MDVSP using a meta-heuristic based on tabu-search method. The main motivation for this work came from the indication that only recently the use of meta-heuristics is being applied to MDVSP context (Pepin et al. 2008 and, also, the limitations listed by Rohde (2008 in his study, which used the branch-and-bound in one of the steps of the heuristic presented to solve the problem, which has increased the time resolution. The research method for solving this problem was based on adaptations of traditional techniques of Operational Research, and provided resolutions presenting very competitive results for the MDVSP such as the cost of the objective function, number of vehicles used and computational time.

    The adipocytes are one of the non-professional phagocytes postulated to be a haven for Mycobacterium tuberculosis during persistence in the human host. The adipocyte - M. tuberculosis interaction data available to date are ex vivo. The present study was primarily aimed to investigate M. tuberculosis infection of adipocytes in course of infection of mouse model. Using primary murine adipocytes, the study first confirmed the infection and immunomodulation of natural adipocytes by M. tuberculosis. The bacilli could be isolated form visceral, subcutaneous, peri renal and mesenteric adipose depots of immunocompetent mice infected with M. tuberculosis intravenously. The bacilli could be isolated from adipocytes and the stromal vascular fraction, even though the numbers were significantly higher in the latter. The bacterial burden in the adipose depots was comparable to those in lungs in the early phase of infection. But with time, the burden in the adipose depots was either decreased or kept under control, despite the increasing burden in the lungs. Infected mice treated with standard anti tubercular drugs, despite effective elimination of bacterial loads in the lungs, continued to harbour M. tuberculosis in adipose depots at loads similar to untreated mice in the late infection phase.

    2005-04-01

    Full Text Available Abstract Background Naltrexone is an effective medication for treatment of alcohol dependence, but its efficacy is limited by lack of adherence to the oral dosage form. A long-acting depot formulation of naltrexone may increase adherence. Methods A single site, 6-week open label study was conducted with 16 alcohol dependent subjects each receiving 300 mg of Naltrexone Depot by intramuscular injection. The main outcomes were safety and tolerability of the Naltrexone Depot formulation, blood levels of naltrexone and its main metabolite 6-beta naltrexol, and self-reported alcohol use. All subjects received weekly individual counseling sessions. Results The medication was well tolerated with 88% of subjects completing the 6-week trial. The most common side effect experienced was injection site complications. There were no serious adverse events. Subjects had naltrexone and 6-beta-naltrexol concentrations throughout the trial with mean values ranging from 0.58 ng/mL to 2.04 ng/mL and 1.51 ng/mL to 5.52 ng/mL, respectively, at each sampling time following administration. Compared to baseline, subjects had significantly reduced number of drinks per day, heavy drinking days and proportion of drinking days. Conclusion Naltrexone Depot is safe and well tolerated in alcoholics and these findings support the further investigation of its utility in larger double-blind placebo controlled trials.

    The isolation of adipose-derived stem cells (ASCs) is an important method in the field of adipose tissue biology, adipogenesis, and extracellular matrix (ECM) remodeling. In vivo, ECM-rich environment consisting of fibrillar collagens provides a structural support to adipose tissues during the progression and regression of obesity. Physiological ECM remodeling mediated by matrix metalloproteinases (MMPs) plays a major role in regulating adipose tissue size and function1, 2. The loss of physiological collagenolytic ECM remodeling may lead to excessive collagen accumulation (tissue fibrosis), macrophage infiltration, and ultimately, a loss of metabolic homeostasis including insulin resistance3, 4. When a phenotypic change of the adipose tissue is observed in gene-targeted mouse models, isolating primary ASCs from fat depots for in vitro studies is an effective approach to define the role of the specific gene in regulating the function of ASCs. In the following, we define an immunomagnetic separation of Sca1high ASCs. PMID:27583550

    Full Text Available When full automation is realized in factory automation, material handing systems (MHS have a fairly important role. The most technological development among MHS's has been concentrated on Automated Guided Vehicle (AGV systems. An AGV is an unmanned vehicle capable of following an external guidance signal to deliver a unit load from destination to destination. Nowadays, there are a lot of applications lie along service sector to industrial sector because of flexibilities of AGVs. In this study, these subjects have been applied on the Army Aviation Depot Maintenance where aircraft's and aircraft parts can be maintained and overhauled is an application fields of AGV, requiring AGV numbers and AGV routing. The AGV routing problem and traveling sales person (TSP problems are identical problems; where the AGV routing problem is formulated as a zero one integer programming. Examples are presented to demonstrate the approach and LINGO has been used to solve the example.

    2008-01-01

    High auditory sensitivity, sharp frequency selectivity, and otoacoustic emissions are signatures of active amplification of the cochlea. The human ear can also detect very large amplitude sound without being damaged as long as the exposed time is not too long. The outer hair cells are believed as the best candidate for the active force generator of the mammalian cochlea. In this paper, we propose a new model for the basilar membrane oscillation which successfully describes both the active and the protective mechanisms by employing an energy depot concept and a critical velocity of the basilar membrane. One of the main results is that thermal noise in the absence of external stimulation can be amplified leading to the spontaneous basilar membrane oscillation. The compressive response of the basilar membrane at the characteristic frequency and the dynamic response to the stimulation are consistent with the experimental results as expected. Our model also shows the nonlinear distortion of the response of the bas...

    Full Text Available Distribution and optimum allocation of emergency resources are the most important tasks, which need to be accomplished during crisis. When a natural disaster such as earthquake, flood, etc. takes place, it is necessary to deliver rescue efforts as quickly as possible. Therefore, it is important to find optimum location and distribution of emergency relief resources. When a natural disaster occurs, it is not possible to reach some damaged areas. In this paper, location and multi-depot vehicle routing for emergency vehicles using tour coverage and random sampling is investigated. In this study, there is no need to visit all the places and some demand points receive their needs from the nearest possible location. The proposed study is implemented for some randomly generated numbers in different sizes. The preliminary results indicate that the proposed method was capable of reaching desirable solutions in reasonable amount of time.

    Paraphilia is a psychiatric disease that has been difficult to cure. However, recently developed therapeutic methods hold promise. The patient was a 20-yr-old male with chief complaints of continuous masturbation, genital exposure, and aggressive behavior that started 2 yr ago. We administered leuprorelin 3.6 mg intramuscular injection per month, a depot gonadotrophin-releasing hormone analogue, to this patient who a severe mentally retardation with paraphilia. The clinical global impression (CGI)-severity, CGI-improvement and aberrant behavior checklist were performed. After one month, we observed significant improvement in symptoms, such as decreases of abnormal sexual behavior and sexual desire. The GnRH analogues are suggested to be used as an alternative or supplementary therapeutic method for sexual offenders after clinical studies.

    Full Text Available In this paper, we consider the multi depot heterogeneous vehicle routing problem with time windows in which vehicles may be replenished along their trips. Using the modeling technique in a new-generation solver, we construct a novel formulation considering a rich series of constraint conditions and objective functions. Computation results are tested on an example comes from the real-world application and some cases obtained from the benchmark problems. The results show the good performance of local search method in the efficiency of replenishment system and generalization ability. The variants can be used to almost all kinds of vehicle routing problems, without much modification, demonstrating its possibility of practical use.

    Full Text Available Planning Operation subdivision at PT Pertamina has to generate supply decisions includingmain depot to supply, supply point and transportation mode. However, the variability inplanning a supply schedule renders the process of determining a supply decision asineffective. The last assessment on uncertainties was done at 2006 and has not beenconsidered during decision making process. On the other hand, the result of this researchindicates that the uncertainty level is too high to be ignored and the poor informationexchange between the regional offices and the head office decreases the Planning Operation’sability to create plans that covers the company condition. This paper proposes an appropriatesafety stock to withstand the uncertainties and a supply scheduling process that also considersuncertainties by using Monte-Carlo Simulation with random numbers to simulate the events inthe upcoming period.Key words: inventory management, distribution planning, managing uncertainties, montecarlosimulation

    2006-01-01

    Full Text Available High discontinuation rates for depot medroxyprogesterone acetate (DMPA in adolescents may contribute to the number of unintended pregnancies. Many cite vaginal bleeding as a reason for discontinuing DMPA use. In this study, we attempted to determine if treating DMPA-associated vaginal bleeding with monophasic oral contraceptive pills (OCP raised continuation rates. A total of 131 patients who reported vaginal bleeding while on DMPA were included in this study and 83 were treated with monophasic OCP. Of those who received OCP, 38.7% reported that vaginal bleeding stopped completely, 51.8% reported that vaginal bleeding stopped temporarily, and 6.0% reported no change. Overall, 94% of enrolled patients who received OCP as a treatment for DMPA-associated vaginal bleeding continued DMPA use. Our findings indicate that vaginal bleeding due to DMPA can be successfully treated, leading to improvement in continuation rates.

    Science.gov (United States)

    1993-01-01

    Depot-medroxyprogesterone acetate (DMPA) is a long-acting progestational contraceptive, which is administered by injection. It was developed in the mid-1960s, when it was seen as a method that would be particularly useful for women seeking reversible contraception who had difficulty taking a pill every day. DMPA has been shown to be a highly effective contraceptive, and it has proved acceptable in a variety of settings. The drug is licensed as a contraceptive in more than 90 countries and has been widely used in a number of them, such as Thailand and New Zealand. On a worldwide basis, the licensing, acceptability, and prevalence of use have been influenced by concern that DMPA may increase the risk of cancer. Cancer of the breast has been a particular concern. This Memorandum reviews comprehensively the results of toxicological tests in animals and epidemiological studies in humans concerning the carcinogenicity of DMPA. PMID:8313485

    A review of all available data including those from the WHO Collaborative Study of Neoplasia and Steroid Contraceptives has shown no increased risk of cancers of the breast, endometrium, ovary or liver in women using depot-medroxyprogesterone acetate (DMPA). The issue of a causal association between DMPA use and cervical cancer is as yet unresolved and will require the accumulation of additional data. To date, in the WHO study only a small number of women have used DMPA for prolonged periods or have had a long interval since first use. Information on cancer risk in these women can only be gained by continuing the present study or by initiating additional studies focused on these specific topics. PMID:2945666

    To evaluate whether serum adipocytokine concentrations, controlling for baseline adiposity, are predictive of adipose weight gain in adolescents initiating depot medroxyprogesterone acetate (DMPA). Percent body fat was measured at baseline and 6 months. Baseline serum adipocytokine concentrations were quantified. Mean percent body fat was 31.6% (±7.6) at baseline and 33.5% (±7.6) at 6 months. In multivariable linear regression modeling (adjusted for baseline percent body fat), Hispanic ethnicity and baseline serum adiponectin concentration were inversely associated (p≤.05) with absolute change in percent body fat at 6 months. Serum adiponectin concentration may be useful for assessing risk of DMPA-associated adipose gains. Copyright © 2015 Elsevier Inc. All rights reserved.

    2012-01-01

    BACKGROUND Lipodystrophy is a rare condition causing severe insulin resistance and frank diabetes. Depot medroxyprogesterone acetate (DMPA), a commonly used contraceptive, may worsen glucose tolerance in diabetics and those with lipodystrophy. CASE A young woman with generalized lipodystrophy, who previously required greater than 1,000 units of insulin daily, had a normal hemoglobin A1c on leptin and metformin only. After an injection of DMPA, she developed severe hyperglycemia. Her levels returned to near normal only with extremely high doses of insulin (up to 1,700 units/d) and increased doses of leptin and metformin. CONCLUSION Progestin-only contraceptives may detrimentally affect glucose tolerance, particularly in patients with lipodystrophy, a cause of severe insulin resistance and leptin deficiency. One DMPA injection appeared to profoundly alter glucose metabolism in this patient with frank diabetes resulting from lipodystrophy. The effect of progestin-only contraceptives on glucose tolerance should be monitored closely in any diabetic patient. PMID:18669758

    2017-03-01

    Dubai-one of the seven United Arab Emirates and the Middle East's only "global city"-is gaining a reputation as a transnational medical tourism hub. Characterized by its "medical cosmopolitanism," Dubai is now attracting medical travelers from around the world, some of whom are seeking assisted conception. Dubai is fast becoming known as a new transnational "reprohub" for intracytoplasmic sperm injection (ICSI), the variant of in vitro fertilization designed to overcome male infertility. Based on ethnographic research conducted in one of the country's most cosmopolitan clinics, this article explores the ICSI treatment quests of infertile men coming to Dubai from scores of other nations. The case of an infertile British-Moroccan man is highlighted to demonstrate why ICSI is a particularly compelling "masculine hope technology" for infertile Muslim men. Thus, Muslim men who face barriers to ICSI access in their home countries may become "reprotravelers" to Dubai, an emergent ICSI depot.

    The Umatilla Depot Activity (UMDA) near Hermiston, Oregon, is one of eight US Army installations in the continental United States where lethal unitary chemical agents and munitions are stored, and where destruction of agents and munitions is proposed under the Chemical Stockpile Disposal Program (CSDP). The chemical agent inventory at UMDA consists of 11.6%, by weight, of the total US stockpile. The destruction of the stockpile is necessary to eliminate the risk to the public from continued storage and to dispose of obsolete and leaking munitions. In 1988 the US Army issued a Final Programmatic Environmental Impact Statement (FPEIS) for the CSDP that identified on-site disposal of agents and munitions as the environmentally preferred alternative (i.e., the alternative with the least potential to cause significant adverse impacts), using a method based on five measures of risk for potential human health and ecosystem/environmental effects; the effectiveness and adequacy of emergency preparedness capabilities also played a key role in the FPEIS selection methodology. In some instances, the FPEIS included generic data and assumptions that were developed to allow a consistent comparison of potential impacts among programmatic alternatives and did not include detailed conditions at each of the eight installations. The purpose of this Phase 1 report is to examine the proposed implementation of on-site disposal at UMDA in light of more recent and more detailed data than those included in the FPEIS. Specifically, this Phase 1 report is intended to either confirm or reject the validity of on-site disposal for the UMDA stockpile. Using the same computation methods as in the FPEIS, new population data were used to compute potential fatalities from hypothetical disposal accidents. Results indicate that onsite disposal is clearly preferable to either continued storage at UMDA or transportation of the UMDA stockpile to another depot for disposal.

    Obesity is a leading healthcare issue contributing to metabolic diseases. There is a great interest in non-invasive approaches for quantitating abdominal fat in obese animals and humans. In this work, we propose an automated method to distinguish and quantify subcutaneous and visceral adipose tissues (SAT and VAT) in rodents during obesity and weight loss interventions. We have also investigated the influence of different magnetic resonance sequences and sources of variability in quantification of fat depots. High-fat diet fed rodents were utilized for investigating the changes during obesity, exercise, and calorie restriction interventions (N = 7/cohort). Imaging was performed on a 7T Bruker ClinScan scanner using fast spin echo (FSE) and Dixon imaging methods to estimate the fat depots. Finally, we quantified the SAT and VAT volumes between the L1-L5 lumbar vertebrae using the proposed automatic hybrid geodesic region-based curve evolution algorithm. Significant changes in SAT and VAT volumes (pfat quantification correlation between FSE (with and without water suppression) sequences and Dixon for SAT and VAT were 0.9709, 0.9803 and 0.9955, 0.9840 respectively. The algorithm significantly reduced the computation time from 100 sec/slice to 25 sec/slice. The pre-processing, data-derived contour placement and avoidance of strong background-image boundary improved the convergence accuracy of the proposed algorithm. We developed a fully automatic segmentation algorithm to quantitate SAT and VAT from abdominal images of rodents, which can support large cohort studies. We additionally identified the influence of non-algorithmic variables including cradle disturbance, animal positioning, and MR sequence on the fat quantification. There were no large variations between FSE and Dixon-based estimation of SAT and VAT.

    To evaluate the effect of metformin on basal and insulin-induced glucose uptake in subcutaneous and visceral preadipocyte-derived adipocytes from obese and non-obese patients, preadipocytes were obtained from subcutaneous and visceral fat depots during abdominal surgery. Differentiation efficiency was evaluated by measurement of intracellular triglyceride accumulation. Preadipocyte-derived adipocytes were treated with metformin (1 mM) for 24 h with or without the addition of insulin (100 nM) for 20 min and glucose uptake was measured. In cells from each donor, intracellular triglyceride accumulation was more abundant in subcutaneous preadipocyte-derived adipocytes than in visceral preadipocyte-derived adipocytes (p < 0.001). Insulin stimulated glucose uptake in subcutaneous preadipocyte-derived adipocytes from both non-obese and obese patients (p < 0.001 vs. basal). In visceral preadipocyte-derived adipocytes, insulin did not increase basal glucose uptake. In subcutaneous preadipocyte-derived adipocytes from non-obese and obese patients, metformin alone increased glucose uptake to 2.7 +/- 0.2 (p < 0.001) and 2.1 +/- 0.1 fold (p < 0.001) respectively. Metformin increased glucose uptake in visceral preadipocyte-derived adipocytes from non-obese (1.7 +/- 0.1 fold vs. basal, p < 0.001) and obese (2.0 +/- 0.2 fold vs. basal, p < 0.001) patients. Combined treatment with metformin and insulin increased glucose uptake in subcutaneous preadipocyte-derived adipocytes from both non-obese and obese patients (p < 0.001 vs. insulin alone). In preadipocyte-derived adipocytes glucose uptake is induced by metformin independent of the fat depot origin of the preadipocytes (subcutaneous or visceral) and the obesity state of the patients (non-obese or obese). In adipocytes, metformin seems to induce glucose uptake independent of insulin suggesting an alternative mechanism of action of this drug.

    The purpose of this Phase I report is to examined the proposed implementation of on-site disposal at Anniston Army Depot (ANAD) in light of more detailed and more recent data than those included in the Final Programmatic Environmental Impact Statement (EPEIS). Two principal issues are addressed: (1) whether or not the new data would result in identification of on-site disposal at ANAD as the environmentally preferred alternative (using the same selection method and data analysis tools as in the FPEIS), and (2) whether or not the new data indicate the presence of significant environmental resources that could be affected by on-site disposal at ANAD. In addition, a status report is presented on the maturity of the disposal technology (and now it could affect on-site disposal at ANAD). Inclusion of these more recent data into the FPEIS decision method resulted in confirmation of on-site disposal for ANAD. No unique resources with the potential to prevent or delay implementation of on-site disposal at ANAD have been identified. A review of the technology status identified four principal technology developments that have occurred since publication of the FPEIS and should be of value in the implementation of on-site disposal at ANAD: the disposal of nonlethal agent at Pine Bluff Arsenal, located near Pine Bluff, Arkansas; construction and testing of facilities for disposal of stored lethal agent at Johnston Atoll, located about 1300 km (800 miles) southwest of Hawaii in the Pacific Ocean; lethal agent disposal tests at the chemical agent pilot plant operations at Tooele Army Depot, located near Salt Lake City, Utah; and equipment advances. 18 references, 13 figs., 10 tabs.

This poses a problem for use in vivo as oral administration requires a high concentration for significant levels to reach target tissues, and injection of the compound in a dimethyl sulfoxide- or ethanol-based vehicle is usually not desirable during long-term treatment. A depot injection of NAE 16:0 was successfully emulsified in sterile corn oil (10 mg/kg and administered in young DBA/2 mice in order to elevate baseline levels of NAE 16:0 in target tissues. NAE 16:0 levels were increased in various tissues, particularly in the retina, 24 and 48 hours following injections. Increases ranged between 22% and 215% (above basal levels in blood serum, heart, brain, and retina and induced an entourage effect by increasing levels of other 18 carbon N-Acylethanolamines (NAEs, which ranged between 31% and 117% above baseline. These results indicate that NAE 16:0 can be used as a depot preparation, avoiding the use of inadequate vehicles, and can provide the basis for designing tissue-specific dosing regimens for therapies involving NAEs and related compounds.

    The Multiple Traveling Salesman Problem (MTSP) is the extension of the Traveling Salesman Problem (TSP) in which the shortest routes of m salesmen all of which start and finish in a single city (depot) will be determined. If there is more than one depot and salesmen start from and return to the same depot, then the problem is called Fixed Destination Multi-depot Multiple Traveling Salesman Problem (MMTSP). In this paper, MMTSP will be solved using the Ant Colony Optimization (ACO) algorithm. ACO is a metaheuristic optimization algorithm which is derived from the behavior of ants in finding the shortest route(s) from the anthill to a form of nourishment. In solving the MMTSP, the algorithm is observed with respect to different chosen cities as depots and non-randomly three parameters of MMTSP: m, K, L, those represents the number of salesmen, the fewest cities that must be visited by a salesman, and the most number of cities that can be visited by a salesman, respectively. The implementation is observed with four dataset from TSPLIB. The results show that the different chosen cities as depots and the three parameters of MMTSP, in which m is the most important parameter, affect the solution.

    An in-situ forming gel-like depot, prepared by using an appropriate polyaspartamide-polylactide graft copolymer, has been employed to release in a sustained way sulpiride. α,β-poly(N-2-hydroxyethyl)-D,L-aspartamide-g-polylactic acid (PHEA-g-PLA) has been used as a polymer component. Its physicochemical properties make possible to dissolve it in N-methyl-2-pyrrolidone, with the obtainment of a solution able to form a gel-like depot once injected into a physiological medium. Cell compatibility of PHEA-g-PLA depot has been investigated, using murine dermal fibroblasts as cell model. 3-(4,5-Dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt assay and fluorescence microscopy have been employed to evaluate cell viability and morphology after contact with PHEA-g-PLA depot. Pharmacokinetic parameters of sulpiride released from depot have been determined following subcutaneous administration to rabbits and compared with corresponding parameters following administration of free sulpiride solution. It has been demonstrated that the system does not affect significantly the viability of fibroblasts and is able to sustain the release of sulpiride until a week, with a burst effect dependent on the initial weight ratio polymer/drug. In-vivo release profiles and pharmacokinetic parameters suggest that PHEA-g-PLA depot could have interesting clinical applications for a once a week administration of poorly soluble drugs to humans or animals. © 2014 Royal Pharmaceutical Society.

  20. Impact evaluation of an orbital depot on on-orbit servicing infrastructures dedicated to modularized earth-orbiting platforms

    Sarton du Jonchay, Tristan; Ho, Koki

    2017-03-01

    This paper aims to quantify the responsiveness of two on-orbit servicing infrastructures providing services to multiple serviceable platforms in coplanar medium Earth orbit (MEO) and geostationary orbit (GEO). The platforms to be serviced are assumed to be made of elementary units (EUs). EUs are small standardized structural units capable of aggregating with each other and gathering the key functions of a typical satellite within the size of a 6U cubesat. The first servicing infrastructure considered in this paper, called "Without Depot" (WoD), includes a launch vehicle and a robotic servicer. The second servicing infrastructure, called "With Depot" (WD) includes a launch vehicle, a robotic servicer and an orbital depot of EUs. The responsiveness of these infrastructures is quantified using a queueing theory-based stochastic simulation on Simulink taking into account the launch and platform random failures. The metrics used to quantify the responsiveness are the service completion rate and the average waiting time before an EU is replaced over a 10-year period of operation. With respect to those metrics, it is demonstrated that WD is more responsive than WoD. However, WD is also shown to be likely to cost more than WoD. Finally, the sensitivity of the responsiveness of WD to the capacity of the orbital depot is analyzed to find the minimum storage capacity for which WD is the most responsive. This last result could be of interest for space designers dealing with the sizing of on-orbit servicing infrastructures. We believe that the concept introduced in this paper will be a critical milestone in the design of a responsive integrated space infrastructure dedicated to the development and prosperity of a new MEO/GEO economy.

    Full Text Available BACKGROUND & AIMS: Obesity is a leading healthcare issue contributing to metabolic diseases. There is a great interest in non-invasive approaches for quantitating abdominal fat in obese animals and humans. In this work, we propose an automated method to distinguish and quantify subcutaneous and visceral adipose tissues (SAT and VAT in rodents during obesity and weight loss interventions. We have also investigated the influence of different magnetic resonance sequences and sources of variability in quantification of fat depots. MATERIALS AND METHODS: High-fat diet fed rodents were utilized for investigating the changes during obesity, exercise, and calorie restriction interventions (N = 7/cohort. Imaging was performed on a 7T Bruker ClinScan scanner using fast spin echo (FSE and Dixon imaging methods to estimate the fat depots. Finally, we quantified the SAT and VAT volumes between the L1-L5 lumbar vertebrae using the proposed automatic hybrid geodesic region-based curve evolution algorithm. RESULTS: Significant changes in SAT and VAT volumes (p<0.01 were observed between the pre- and post-intervention measurements. The SAT and VAT were 44.22±9%, 21.06±1.35% for control, -17.33±3.07%, -15.09±1.11% for exercise, and 18.56±2.05%, -3.9±0.96% for calorie restriction cohorts, respectively. The fat quantification correlation between FSE (with and without water suppression sequences and Dixon for SAT and VAT were 0.9709, 0.9803 and 0.9955, 0.9840 respectively. The algorithm significantly reduced the computation time from 100 sec/slice to 25 sec/slice. The pre-processing, data-derived contour placement and avoidance of strong background-image boundary improved the convergence accuracy of the proposed algorithm. CONCLUSIONS: We developed a fully automatic segmentation algorithm to quantitate SAT and VAT from abdominal images of rodents, which can support large cohort studies.

    Subcutaneous depot medroxyprogesterone acetate (DMPA-SC) is a low-dose formulation of depot medroxyprogesterone acetate (DMPA) that nonmedical personnel can administer safely and effectively. We sought to determine United States women's interest in self-administration of DMPA-SC to understand whether such use can overcome barriers to contraceptive access. We analyzed survey data on contraceptive attitudes collected in March-July 2011 from 1592 women at 13 family planning and six abortion clinics throughout the US. A mixed-effects logistic regression model with random site effects examined the determinants of interest in self-administering DMPA-SC. Overall, 21% [95% confidence interval (CI): 19%-23%] of women reported interest in self-administration. A multivariable model found that women currently using DMPA (Adjusted Odds Ratio [AOR]=3.93, 95% CI: 2.37-6.53, p<.001) and women who previously used DMPA (AOR=1.71, 95% CI: 1.26-2.32, p<.001) were more likely to have an interest in DMPA-SC than those who never used it. Women reporting difficulty obtaining or refilling a prescription were almost twice as likely to have interest in DMPA-SC as women who reported no difficulty (AOR=1.99, 95% CI: 1.43-2.77, p<.001). Women surveyed at abortion sites were more likely to report interest in self-administration than women surveyed at family planning sites (AOR=1.55, 95% CI: 1.05-2.30, p<.05). Interest in DMPA-SC was primarily driven by a desire to eliminate unnecessary return visits to a facility for repeat injections. Offering women the option to self-administer DMPA-SC at home can expand access and tailor contraceptive provision to the needs of clients, thus supporting client-centered care. To the extent that self-administration may improve contraceptive continuation, DMPA-SC can prevent unintended pregnancies among women who discontinue DMPA use because of difficulty returning for repeat injections. There is substantial interest in self-administration of DMPA-SC among current

    The purpose of this study was to uncover the effect of exercise training on the expression of autophagy marker proteins in epididymal white adipose tissue (eWAT), inguinal WAT (iWAT), and the stromal vascular fraction (SVF) collected from eWAT. Male Wistar rats aged 4–5 weeks were randomly divided into two groups, sedentary control (n = 7) and exercise-trained (n = 7). Rats in the exercise-trained group were exercised on a treadmill set at a 5° incline 5 days/week for 9 weeks. We determined that the expression levels of an autophagosome-associating form of microtubule-associated protein 1 light chain 3 (LC3)-II and of p62 were significantly higher in eWAT from exercise-trained than from control rats, while those of adipose-specific deletion of autophagy-related protein (ATG7) and lysosomal-associated membrane protein type 2A (LAMP2a) showed no difference between groups. However, in iWAT, the expression levels of LC3-II and ATG7 were significantly higher in exercise-trained than in control rats. The expression of p62 was highly correlated with that of peroxisome proliferator-activated receptor γ (PPARγ), a master regulator of adipogenesis and lipid metabolism, in both WAT types (eWAT, r = 0.856, P < 0.05; iWAT, r = 0.762, P < 0.05), whereas LC3-II and PPARγ levels were highly correlated in eWAT (r = 0.765, P < 0.05) but not in iWAT (r = −0.306, ns). In SVF, the expression levels of LC3II, ATG7, and LAMP2a were significantly higher in exercise-trained than in control rats. These results suggest that exercise training suppresses basal autophagy activity in eWAT, but that this activity is enhanced in iWAT and SVF collected from eWAT. Thus, the adaptation of basal autophagic activity following exercise training exhibits fat depot-specific differences. - Highlights: • Autophagy has been associated with obesity and associated diseases. • We examined exercise-associated rat white adipose tissue (WAT) autophagy markers. • Exercise increased

    Native extracellular matrix (ECM) is a complex fibrous structure loaded with bioactive cues that affects the surrounding cells. A promising strategy to mimicking native tissue architecture for tissue engineering applications is to engineer fibrous scaffolds using electrospinning. By loading appropriate bioactive cues within these fibrous scaffolds, various cellular functions such as cell adhesion, proliferation and differentiation can be regulated. Here, we report on the encapsulation and sustained release of model hydrophobic drug (dexamethasone (Dex)) within beaded fibrillar scaffold of poly(ethylene oxide terephthalate)-poly(butylene terephthalate) (PEOT/PBT), a polyether-ester multiblock copolymer to direct differentiation of human mesenchymal stem cells (hMSCs). The amphiphilic beads act as depots for sustained drug release that is integrated into the fibrillar scaffolds. The entrapment of Dex within the beaded structure results in sustained release of drug over the period of 28 days. This is mainly attributed to the diffusion driven release of Dex from the amphiphilic electrospun scaffolds. In vitro results indicate that hMSCs cultured on Dex containing beaded fibrillar scaffolds exhibit an increase in osteogenic differentiation potential, as evidenced by increased alkaline phosphatase (ALP) activity, compared to the direct infusion of Dex in culture medium. The formation of mineralized matrix is also significantly enhanced due to the controlled Dex release from the fibrous scaffolds. This approach can be used to engineer scaffolds with appropriate chemical cues to direct tissue regeneration. PMID:24794894

    To map access to depot medroxyprogesterone acetate (DMPA) from licensed chemical sellers (LCS); to estimate the proportion of women of reproductive age in areas with access; and to examine affordability and variability of costs. A geospatial analysis was conducted using data collected from 298 women who purchased DMPA from 49 geocoded LCS shops in the Amansie West and Ejisu-Juabeng districts of Ghana from June 4 to August 31, 2012. The women reported on cost and average distance traveled to purchase DMPA. In Amansie West, 21.1% of all women of reproductive age lived within average walking distance and 80.4% lived within average driving distance of an LCS. In Ejisu-Juabeng, 41.9% and 60.1% of women lived within average walking and driving distance, respectively. Distribution of affordability varied across each district. Access to LCS shops is high, and training LCS to administer DMPA would increase access to family planning in Ghana, with associated time and cost savings.

    Injectable depot formulations are aimed at providing long-term sustained release of a drug into systemic circulation, thus reducing plasma level fluctuations and improving patient compliance. The particle size distribution of the formulation in the form of suspension is a key parameter that controls the release rate. In this work, the process of wet stirred media milling (ball milling) of a poorly water-soluble substance has been investigated with two main aims: (i) to determine the parametric sensitivity of milling kinetics; and (ii) to develop scale-up methodology for process transfer from batch to flow-through arrangement. Ball milling experiments were performed in two types of ball mills, a batch mill with a 30ml maximum working volume, and a flow-through mill with a 250ml maximum working volume. Milling parameters were investigated in detail by methodologies of QbD to map the parametric space. Specifically, the effects of ball size, ball fill level, and rpm on the particle breakage kinetics were systematically investigated at both mills, with an additional parameter (flow-rate) in the case of the flow-through mill. The breakage rate was found to follow power-law kinetics with respect to dimensionless time, with an asymptotic d50 particle size in the range of 200-300nm. In the case of the flow-through mill, the number of theoretical passes through the mill was found to be an important scale-up parameter.

    The aim of this study was to assess the effects of the injectable depot-medroxyprogesterone acetate (DMPA) contraceptive on selected blood coagulation parameters in young, healthy new users. The prospective study included 39 healthy women aged 20-39 years, with a body mass index (BMI; kg/m(2) ) < 30, who were never users of DMPA, and who opted to use DMPA (21 women) or a copper intrauterine device (IUD; 18 women). The women in the two groups were matched for age (±1 year) and BMI (±1). Blood samples were obtained from all participants at baseline and at 6 and 12 months. Activated partial thromboplastin time, D-dimer, protein C, antithrombin, protein S, and thrombin generation test (lag time, endogenous thrombin potential, time to peak, and velocity index of thrombin generation) were analyzed. Repeated-measures analysis of variance was used to compare the groups. There were no significant differences between the groups at baseline with respect to any of the parameters evaluated; however, in the DMPA group, D-dimer levels were lower and the time to peak thrombin generation was longer than in the IUD group at 12 months of evaluation. Lower D-dimer and longer time to peak thrombin generation in new users of DMPA suggest a positive profile against hypercoagulability. © 2017 Japan Society of Obstetrics and Gynecology.

    We sought to evaluate satisfaction with timing of administration and continuation rates of depot medroxyprogesterone (DMPA) when given on the initial visit for first-trimester medical abortion. In this pilot study, we administered DMPA within 15 min of mifepristone administration. Participants were followed up in the clinic 7 days after enrollment and were contacted at 14 days, 28 days and 3, 6, 9 and 12 months by telephone. We assessed satisfaction with contraception timing, DMPA continuation, bleeding patterns and abortion completion. Twenty women were enrolled. At 7-day follow-up, 18 of 19 contacted participants (94.7%) were satisfied with timing of DMPA administration. Ten of 19 participants (52.6%) discontinued DMPA after the first injection. At 1 year, 3 participants out of 19 were continuing DMPA (15.7%). The median number of bleeding days after abortion was 19. Three participants had medical abortion failure. In the first year after abortion, there were four known repeat pregnancies. The timing of initiation of DMPA on the initial visit for medical abortion is satisfactory to women, but its influence on medical abortion efficacy requires further study. Continuation rates for DMPA were low in our sample. This pilot study provides groundwork for future larger studies to assess initiation of the injectable contraceptive DMPA on the day of mifepristone for medical abortion, but low continuation rates of DMPA in our sample emphasize the importance of access to intrauterine devices and implants after abortion.

    Observational analyses have suggested that women using the injectable contraceptive depot medroxyprogesterone acetate (DMPA) may have heightened risk of acquiring HIV. However, those analyses were potentially confounded by sexual behavior, with possible differential condom use and reporting by women using DMPA versus no contraception. In a cross-sectional study, we measured the presence of a biomarker of recent condomless sex (Y chromosomal [Yc] DNA) in vaginal swabs from HIV-uninfected African women who had an HIV-infected partner and reported 100 % condom use. Half of the samples tested were from women reporting DMPA and half were from women using no contraception. Among 428 specimens tested (213 from DMPA users and 215 from women using no contraception), 32.0 % had Yc DNA detected, with a mean of 193 copies/10,000 human cells (range 0.1-8201). The frequency of detection did not differ by contraceptive use: 34.2 % of DMPA users versus 29.8 % of women using no contraception, adjusted odds ratio 1.3 (95 % confidence interval 0.9-2.0). These results suggest that inaccurate reporting of condom use by DMPA users may not account for the heightened risk of HIV acquisition among DMPA users in some observational studies.

    Brown adipose tissue (BAT) has been proposed as a potential target tissue against obesity and its related metabolic complications. Although the molecular and functional characteristics of BAT have been intensively studied in rodents, only a few studies have used human BAT specimens due to the difficulty of sampling human BAT deposits. We established a novel positron emission tomography and computed tomography-guided Bergström needle biopsy technique to acquire human BAT specimens from the supraclavicular area in human subjects. Forty-three biopsies were performed on 23 participants. The procedure was tolerated well by the majority of participants. No major complications were noted. Numbness (9.6%) and hematoma (2.3%) were the two minor complications noted, which fully resolved. Thus, the proposed biopsy technique can be considered safe with only minimal risk of adverse events. Adoption of the proposed method is expected to increase the sampling of the supraclavicular BAT depot for research purposes so as to augment the scientific knowledge of the biology of human BAT.

    Full Text Available The Nyírlugos obsidian core depot find is one of the most important lithic assemblages in the collection of the Hungarian National Museum (HNM. The original set comprised 12 giant obsidian cores, of which 11 are currently on the permanent archaeological exhibition of the HNM. One of the cores is known to be inDebrecen. The first publication attributed the hoard, on the strength of giant (flint blades known from the Early and Middle Copper Age Tiszapolgár and Bodrogkeresztúr cultures, to the Copper Age. In the light of recent finds it is more likely to belong to the Middle Neolithic period. The source area was defined as Tokaj Mts., about100 kmto the NW from Nyírlugos. The size and beauty of the exceptional pieces exclude any invasive analysis. Using Prompt Gamma Activation Analysis (PGAA, we can measure major chemical components and some key trace elements of stone artefacts with adequate accuracy to successfully determine provenance of obsidian. Recent methodological development also facilitated the study of relatively large objects like the Nyírlugos cores. The cores were individually measured by PGAA. The results show that the cores originate from the Carpathian 1 sources, most probably the Viničky variety (C1b. The study of the hoard as a batch is an important contribution to the assessment of prehistoric trade and allows us to reconsider the so-called Carpathian, especially Carpathian 1 (Slovakian sources.

    Lanreotide Autogel/Depot effectively controls symptoms in patients with carcinoid syndrome associated with neuroendocrine tumours. Data on patient-reported outcomes are sparse. To evaluate the effect of lanreotide on patient-reported outcomes (PROs) with carcinoid syndrome. This was an international, open-label, observational study of adults with neuroendocrine tumours and history of diarrhoea, receiving lanreotide for >3 months for relief of carcinoid syndrome symptoms. The primary PRO measure was satisfaction with diarrhoea control. Secondary PRO measures included severity, change in symptoms and impact on daily life of diarrhoea; and patient satisfaction with flushing control. Of 273 patients enrolled, 76% were 'completely' or 'rather' satisfied with diarrhoea control; 79% reported improvement in diarrhoea with lanreotide. The proportion of patients with 'mild', 'minimal', or 'no diarrhoea' increased from 33% before treatment to 75% during treatment; 75% were unconcerned about the impact of diarrhoea on daily life. Satisfaction with flushing control amongst patients with significant flushing at treatment initiation was 73%. Lanreotide treatment was associated with improvements in symptoms as well as a range of PROs in patients with neuroendocrine tumours and carcinoid syndrome (ClinicalTrials.gov: NCT01234168).

    Galactorrhea is rarely mentioned as a possible side effect of the use of Depot-Medroxyprogesterone Acetate (DMPA). Over the last few years, we have noticed an increased number of patients complaining of galactorrhea. A review of clinical data showed that between 1999 and 2005, 360 adolescents in our clinic used DMPA for at least 6 months. After medical follow-up, 13 (3.6%) of these patients were found to have developed galactorrhea. The mean age of the patients was 19.4 years with a range from 13-24. Prolactin levels in these patients were normal, and in all subjects, the galactorrhea resolved spontaneously within the next year in both patients who continued use and those who discontinued use of DMPA. It appears that galactorrhea is a benign side effect and as previous reports have suggested, it did not seem to be related to changes in Prolactin levels in our patients. It is thought that this is a progesterone-mediated effect. We believe that reassurance and education of patients is sufficient and there is no evidence of need for further intervention. Since the sample size is small in this study, additional research is recommended as to validate the presence of progesterone-mediated effects secondary to the use of DMPA.

    A massive vapour cloud explosion occurred at the Buncefield fuel depot near Hemel Hempstead, UK, in the morning of 2005 December 11. The explosion was the result of an overflow from one of the storage tanks with the release of over 300 tons of petrol and generating a vapour cloud that spread over an area of 80000 m2, before being ignited. Considerable damage was caused in the vicinity of the explosion and a total of 43 people were injured. The explosion was detected by seismograph stations in the UK and the Netherlands and by infrasound arrays in the Netherlands. We analysed the seismic recordings to determine the origin time of 06:01:31.45 +/-0.5 s (UTC) from P-wave arrival times. Uncertainties in determination of origin time from acoustic arrival times alone were less than 10 s. Amplitudes of P-, Lg and primary acoustic waves were measured to derive decay relationships as function of distance. From the seismic amplitudes we estimated a yield of 2-10 tons equivalent to a buried explosion. Most seismic stations recorded primary and secondary acoustic waves. We used atmospheric ray tracing to identify the various travel paths, which depend on temperature and wind speed as function of altitude, leading to directional variation. Refracted waves were observed from the troposphere, stratosphere and thermosphere with a good match between observed and calculated traveltimes. The various wave types were also identified through array processing, which provides backazimuth and slowness, of recordings from an infrasound array in the Netherlands. The amplitude of stratospheric refracted acoustic waves recorded by the array microbarometers was used to estimate a yield of 21.6 (+/-5) tons TNT equivalent. We have demonstrated through joint seismo-acoustic analysis of the explosion that both the seismic velocity model and the atmospheric model are sufficient to explain the observed traveltimes.

    Weight gain has been cited by women as one of the main reasons for discontinuation of the contraceptive depot medroxyprogesterone acetate (DMPA). This study aimed to evaluate binge eating and the biochemical markers of appetite in new DMPA users. In this prospective non randomized study with adult healthy women, twenty-eight users of DMPA and twenty-five users of a copper intrauterine device (IUD) were paired for age (±1 year) and body mass index (BMI) (±1 kg/m(2)). We evaluated binge eating using the Binge Eating Scale (BES), the serum levels of neuropeptide Y, leptin and adiponectin, and the BMI at baseline and after 12 months in both groups. For statistical analysis was used ANOVA for to compare the means of the repeated measurements. Mean age was 29.6 and 28.6 years and BMI was 23.9 and 24.5 kg/m(2) for the DMPA and IUD groups, respectively. After 12 months, the frequency of the scores of binge eating remained low in both groups. There were no significant differences between the groups at 12 months with respect to BMI, levels of NPY, leptin, adiponectin, and BES scores. Healthy adult women did not present with central stimulation of appetite or binge eating disorder in their first year after starting use of DMPA. This study reinforces the use of the contraceptive DPMA and the need for guidance related to living a healthy lifestyle for women who attribute the increase of body weight to the use of the method.

    Depot medroxyprogesterone acetate (DMPA) is the most commonly used hormonal contraceptive method in South Africa. It is frequently administered in the immediate postnatal period, yet it is unclear whether it affects the risk of postnatal depression (PND). To determine whether DMPA increases the risk of PND compared with the copper-containing intrauterine device (IUD) when administered after delivery. A single-blind randomised controlled trial conducted at two teaching hospitals in East London, South Africa. Eligible, consenting women (N=242) requiring postnatal contraception were randomised to receive DMPA or an IUD within 48 hours of childbirth and interviewed at 1 and 3 months postpartum. Depression was measured using the Beck Depression Inventory (BDI-II) and the Edinburgh Postnatal Depression Scale (EPDS). Resumption of sexual intercourse, menstrual symptoms and breastfeeding rates were also assessed. One-month EPDS depression scores were statistically significantly higher in the DMPA arm compared with IUD arm (p=0.04). Three-month BDI-II scores were significantly higher in the DMPA arm than in the IUD arm (p=0.002) and, according to the BDI-II but not the EPDS, more women in the DMPA arm had major depression at this time-point (8 vs 2; p=0.05). There were no statistically significant differences in other outcome measures except that fewer women had resumed sexual activity by 1 month postpartum in the DMPA arm (13% vs 26%; p=0.02). The possibility that immediate postnatal DMPA use is associated with depression cannot be excluded. These findings justify further research with longer follow-up. PACTR201209000419241.

    The primary aim of this study was to examine the association between postpartum predischarge depot-medroxyprogesterone acetate (ppDMPA) and in-hospital breastfeeding initiation, and the secondary exploratory aim was to determine if any racial disparities are associated with ppDMPA receipt or its relationship to breastfeeding initiation. We conducted a cross-sectional retrospective chart review of maternal and newborn records at a large urban academic medical center. Variables extracted included in-hospital feeding choice, obstetrical and sociodemographic variables, infant characteristics, and ppDMPA receipt. The association of ppDMPA and maternal-child characteristics with breastfeeding initiation was examined using logistic regression analysis. Among singleton live births of 919 mother-infant pairs (76.5% African American [AA]), 67% initiated breastfeeding (34% exclusive and 33% mixed) and 31.4% received ppDMPA. Breastfeeding rates differed significantly between AA (60.7%) and non-AA mothers (86.6%), and ppDMPA also differed significantly between AA (37.6%) and non-AA mothers (11.6%). Adjusting for other independent predictors, mothers who received ppDMPA were 1.5 times more likely not to initiate breastfeeding if AA, and 5.2 times more likely not to initiate breastfeeding if non-AA. ppDMPA receipt was independently associated with decreased rates of breastfeeding initiation. Although more AA mothers received ppDMPA than non-AA, the association of ppDMPA with breastfeeding noninitiation was stronger in non-AA than in AA mothers. Future research should examine this question prospectively to ascertain if there is a cause-effect relationship and should address both physiological effects and social perceptions.

    This study examines the effect of a progestogen (depot-medroxyprogesterone acetate, DMPA) on resting metabolic rate (RMR) in a cohort of young, normal-weight healthy women. We hypothesize an increase in RMR and nonshivering thermogenesis (NST) resulting in increased body temperature by DMPA. We performed a prospective cohort study in 13 subjects tested at baseline, 3 weeks and 9 weeks after 150 mg intramuscular DMPA administration. RMR was determined with indirect calorimetry. Secondary endpoints included changes in body mass index (BMI), body composition, temperature and serum levels of estradiol (E2), luteinizing hormone (LH), progesterone and MPA. The percent change in RMR from baseline to week 3 (9%) was significantly higher than the percent change from baseline to week 9 (1.6%) (p=.045). The greatest percent change from baseline to week 3 compared to baseline to week 9 was seen in women initiating DMPA in the luteal phase of the cycle. Hypothalamic-pituitary-ovarian axis was evident by decreases in E2, LH and progesterone. DMPA resulted in increased body temperature with a significant correlation between the change in body temperature and the change in RMR. No change in body composition was seen. RMR and NST increased in young healthy women with normal BMI 3 weeks after receiving the initial dose of 150 mg DMPA for contraception. The effect was augmented when the drug was administered during the luteal phase of the menstrual cycle. DMPA increases RMR and thermogenesis independent of changes in body mass. An increase in weight with chronic DMPA may result from a combination of hyperphagia and abnormal NST in predisposed individuals. Copyright © 2016 Elsevier Inc. All rights reserved.

    To examine the relationship between dietary intake and weight gain among adolescent females initiating depot medroxyprogesterone acetate (DMPA). Prospective observational study. Two urban Adolescent Medicine clinics. 45 postmenarchal females, age 12 to 21, enrolled after self-selecting to initiate DMPA. Participants received 150 mg DMPA intramuscularly every 12 weeks. Height, weight, and 24-hour dietary recall were collected at baseline, 3, 6, and 12 months. Body mass index (BMI) over time calculated as weight (kg)/height (m(2)). Associations between dietary variables and BMI were evaluated with repeated measures analysis of variance modeling. Mean chronological and gynecologic ages were 16.2 ± 1.5 and 4.2 ± 1.8 years, respectively. Mean BMI increased from 23.7 ± 5.3 to 25.3 ± 5.7 over 12 months. Average dietary intake included: 1781.4 ± 554.1 total kilocalories, 228.5 g ± 69.8 carbohydrates, 71.0 g ± 27.3 fat, and 61.0 g ± 20.2 protein. These diet measures were not associated with BMI over time. Dietary fiber, magnesium, and linoleic acid were inversely associated with increased BMI over time (P < .05) CONCLUSION: We found no evidence that general measures of diet (energy, carbohydrates, fat, and protein), as assessed by 24-hour recall, were predictive of weight gain on DMPA. Several nutrients abundant in foods that benefit overall health were inversely associated with increased BMI over time, suggesting that diet quality, rather than quantity, is a more important predictor of DMPA-associated weight gain.

    To evaluate preexposure prophylaxis (PrEP) efficacy for HIV-1 prevention among women using depot medroxyprogesterone acetate (DMPA) for contraception and men whose HIV-1-infected partners use DMPA. Secondary analysis of data from a randomized placebo-controlled trial of daily oral tenofovir and emtricitabine/tenofovir PrEP among heterosexual Kenyan and Ugandan HIV-1 serodiscordant couples. PrEP efficacy for HIV-1 prevention was compared among HIV-1-uninfected women using DMPA versus no hormonal contraception and among HIV-1 uninfected men whose HIV-1-infected female partners used DMPA versus no hormonal contraception. Of 4747 HIV-1 serodiscordant couples, 901 HIV-1-uninfected women used DMPA at some point during follow-up, 1422 HIV-1-uninfected women used no hormonal contraception, 1568 HIV-1-uninfected men had female partners who used DMPA, and 2626 men had female partners who used no hormonal contraception. PrEP efficacy estimates for HIV-1 prevention, compared with placebo, were similar among women using DMPA and those using no hormonal contraception (64.7 and 75.5%, adjusted interaction P = 0.65). Similarly, for men whose female partners used DMPA, PrEP efficacy did not differ from men whose partners used no hormonal contraception (90.0 versus 81.7%, adjusted interaction P = 0.52). PrEP is efficacious for HIV-1 prevention among women using DMPA and men whose partners use DMPA, suggesting PrEP could mitigate the potential increased HIV-1 acquisition and transmission risks that have been associated with DMPA use. Women at risk for HIV-1 choosing DMPA could maintain this contraceptive method and add PrEP to achieve prevention of unintended pregnancy and HIV-1.

    To assess the association between medroxyprogesterone acetate exposure and bone mineral density (BMD) loss and weight change in adolescents. Forty-eight-week prospective, randomized trial conducted May 2012-April 2014. Recruitment occurred in the general community and outpatient clinics in central Ohio. Self-referred sample of 34 female adolescents aged 12-21 years initiating depot medroxyprogesterone acetate (DMPA). Randomization to 1 of 3 DMPA doses (150, 104, or 75 mg) given intramuscularly every 12 weeks for 48 weeks. Absolute and percent change in BMD from 0-48 weeks at the L1-L4 lumbar spine, total hip, and femoral neck; absolute and percent change in weight at 48 weeks. DMPA dose was associated with medroxyprogesterone acetate exposure as evidenced by a direct relationship (P < .001) between dose group and area under the concentration time curve. At 48 weeks, no significant BMD decreases were seen in the 75 mg dose group. The 104 and 150 mg dose groups experienced significant (P < .01) decreases in L1-L4 lumbar spine BMD (3.1% and 4.0%, respectively). The 150 mg group also had significant (P < .05) decreases in total hip (3.0%) and femoral neck (4.0%) BMD. No group differences in weight change were observed. No pregnancies occurred in any DMPA dose group. Our data provide evidence of a dose-response relationship between DMPA and BMD loss. Intramuscular DMPA doses less than 150 mg can decrease risk of BMD loss in adolescents. The risk/benefit ratio of lower-dose DMPA should be further investigated in larger and more diverse adolescent populations.

    Objective To examine if early weight gain in depot medroxyprogesterone acetate (DMPA) users predicts continued excessive weight gain and to identify risk factors of early weight gain in DMPA users. Methods DMPA users (N=240) were assessed prior to initiating contraception and every 3 months for 36 months. Early weight gain was defined as over 5% baseline weight gain within 6 months of DMPA use. Mean weight gain at 6-month intervals was estimated based on early weight gain status (at or below 5% gain vs. above 5% gain). Multiple logistic and mixed-model regression analyses were used. Results About one-fourth of DMPA users had early weight gain. The mean weight gain of the at or below 5% group and above 5% group was 0.63 kg and 8.04 kg, 1.48 kg and 10.86 kg, and 2.49 kg and 11.08 kg after 12, 24, and 36 months (P < 0.001 at all observations), respectively. Early weight gainers also had a much steeper slope of weight gain over time than the regular weight gainers (0.35 kg/month vs. 0.08 kg/month, P < 0.001). Risk factors for early weight gain were: BMI less than 30 (OR 4.00, 95% confidence interval (CI): 1.513 – 10.455), parity (OR 2.23, 95% CI: 1.040 – 4.761), and self-reported increased appetite after 6 months of DMPA use (OR 3.06, 95% CI: 1.505 – 6.214). Conclusion Most DMPA users who gain excessive weight experience more than a 5% weight increase within 6 months. These data help physicians predict who is at risk of excessive gain and counsel them appropriately. PMID:19622988

The purpose of this study was to determine whether gene expression levels of cannabinoid type 1 receptor (CB1 and fatty acid amide hydrolase (FAAH are different in subcutaneous abdominal and gluteal adipose tissue, and whether hypocaloric diet and aerobic exercise influence subcutaneous adipose tissue CB1 and FAAH gene expression in obese women. Methods Thirty overweight or obese, middle-aged women (BMI = 34.3 ± 0.8 kg/m2, age = 59 ± 1 years underwent one of three 20-week weight loss interventions: caloric restriction only (CR, N = 9, caloric restriction plus moderate-intensity aerobic exercise (CRM, 45-50% HRR, N = 13, or caloric restriction plus vigorous-intensity aerobic exercise (CRV, 70-75% HRR, N = 8. Subcutaneous abdominal and gluteal adipose tissue samples were collected before and after the interventions to measure CB1 and FAAH gene expression. Results At baseline, FAAH gene expression was higher in abdominal, compared to gluteal adipose tissue (2.08 ± 0.11 vs. 1.78 ± 0.10, expressed as target gene/β-actin mRNA ratio × 10-3, P Conclusions There are depot differences in subcutaneous adipose tissue endocannabinoid system gene expression in obese individuals. Aerobic exercise training may preferentially modulate abdominal adipose tissue endocannabinoid-related gene expression during dietary weight loss. Trial Registration ClinicalTrials.gov: NCT00664729.

    Silica-based ordered mesoporous materials are very attractive matrices to prepare smart depot systems for several kinds of therapeutic agents. This work focuses on the well-known SBA-15 mesoporous silica and lysozyme, an antimicrobial protein. In order to improve the bioadhesion properties of SBA-15 particles, the effect of hyaluronic acid (HA) functionalization on lysozyme adsorption was investigated. SBA-15 samples having high (H-SBA) and low (L-SBA) levels of functionalization were analyzed during the three steps of the preparations: (1) introduction of the -NH2 groups to obtain the SBA-NH2 samples; (2) functionalization with HA to obtain the SBA-HA matrices; (3) adsorption of lysozyme. All silica matrices were characterized through N2-adsorption/desorption isotherms, small-angle X-ray scattering, transmission electron microscopy, thermogravimetric analysis, and Fourier transform infrared spectroscopy. The whole of the experimental data suggests that a high level of functionalization of the silica surface allows for a negligible lysozyme adsorption mainly due to unfavorable electrostatic interactions (H-SBA-NH2) or steric hindrance (H-SBA-HA). A low degree of functionalization of the silica surface brings about a very good performance toward lysozyme adsorption, being 71% (L-SBA-NH2) and 63% (L-SBA-HA) respectively, compared to that observed for original SBA-15. Finally, two different kinetic models--a "pseudo-second order" and a "intraparticle diffusion"--were compared to fit lysozyme adsorption data, the latter being more reliable than the former.

    The Cryogenic On-Orbit Liquid Depot Storage, Acquisition, and Transfer Satellite (COLD-SAT) will perform subcritical liquid hydrogen handling experiments under low gravity conditions to provide engineering data for future space transportation missions. Comprising the four Class 1 enabling experiments are tank press control, tank chilldown, tank no-vent fill, and liquid acquisition device fill/refill. The nine Class 2 enhancing experiments are tanker thermal performance, pressurization, low-gravity setting and outflow, liquid acquisition device performance, transfer line chilldown, outflow subcooling, low-gravity vented fill, fluid dumping, and advanced instrumentation. Consisting of an experiment module mated to a spacecraft bus, COLD-SAT will be placed in an initial 1300 km circular orbit by an Atlas commercial launch vehicle, and will perform experiments in a semi-autonomous mode for a period of up to six months. The three-axis controlled spacecraft bus provides electric power, control and data management, communications, and attitude control along with propulsive acceleration levels ranging from 10(exp -6) to 10(exp -4) g. It is desired to understand the effects that low acceleration levels might have on the heat and mass transfer processes involved in some of the experiments. The experiment module contains the three liquid hydrogen tanks, valves, pressurization and pumping equipment, and instrumentation. Within the highly insulated tanks are specialized fluid management equipment that might be used in future space transportation systems. At launch all the liquid hydrogen for the experiments is contained in the largest tank, which has helium-purged insulation to prevent cryo-pumping of air on the launch pad. The tank is loaded by the hydrogen tanking system used for the Centaur upper stage of the Atlas. After reaching orbit the two smaller tanks become receivers for fluid transfers, and when tanked, become the vessels for performing many of the experiments.

    Full Text Available Visceral fat accretion is a hallmark of aging and is associated with aging-induced metabolic dysfunction. PPARγ agonist was reported to improve insulin sensitivity by redistributing fat from visceral fat to subcutaneous fat. The purpose of this study was to investigate the underlying mechanisms by which aging affects adipose tissue remodeling in a type 2 diabetic animal model and through which PPARγ activation modulates aging-related fat tissue distribution. At the ages of 21, 31 and 43 weeks, OLETF rats as an animal model of type 2 diabetes were evaluated for aging-related effects on adipose tissue metabolism in subcutaneous and visceral fat depots. During aging, the ratio of visceral fat weight to subcutaneous fat weight (V/S ratio increased. Aging significantly increased the mRNA expression of genes involved in lipogenesis such as lipoprotein lipase, fatty acid binding protein aP2, lipin 1, and diacylglycerol acyltransferase 1, which were more prominent in visceral fat than subcutaneous fat. The mRNA expression of adipose triglyceride lipase, which is involved in basal lipolysis and fatty acid recycling, was also increased, more in visceral fat compared to subcutaneous fat during aging. The mRNA levels of the genes associated with lipid oxidation were increased, whereas the mRNA levels of genes associated with energy expenditure showed no significant change during aging. PPARγ agonist treatment in OLETF rats resulted in fat redistribution with a decreasing V/S ratio and improved glucose intolerance. The genes involved in lipogenesis decreased in visceral fat of the PPARγ agonist-treated rats. During aging, fat distribution was changed by stimulating lipid uptake and esterification in visceral fat rather than subcutaneous fat, and by altering the lipid oxidation.

    Full Text Available We have developed an in vitro hepatocyte-adipose tissue explant (ATE co-culture model enabling examination of the effect of visceral and subcutaneous adipose tissues on primary rat hepatocytes. Initial analyses of inflammatory marker genes were performed in fractionated epididymal or inguinal adipose tissues. Expressions of inflammation related genes (IL-6, TNF-α, COX-2 were higher in the inguinal than the epididymal ATE. Similarly, expressions of marker genes of macrophage and monocyte (MPEG-1, CD68, F4/80, CD64 were higher in the stromal vascular fraction (SVF isolated from inguinal ATE than that from epididymal ATE. However, expressions of lipolysis related genes (ATGL, HSL, perilipin-1 were higher in the epididymal adipocytes than inguinal adipocytes. Moreover, secretion of IL-6 and PGE(2 was higher from inguinal ATEs than from epididymal ATEs. There was a trend that the total levels of IL-6, TNF-α and PGE(2 in the media from inguinal ATEs co-cultured with primary rat hepatocytes were higher than that in the media from epididymal ATEs co-cultured with hepatocytes, although the significant difference was only seen in PGE(2. Lipolysis, measured as glycerol release, was similar in the ATEs isolated from inguinal and epididymal adipose tissues when cultured alone, but the glycerol release was higher in the ATEs isolated from epididymal than from inguinal adipose tissue when co-cultured with hepatocytes. Compared to epididymal ATEs, the ATEs from inguinal adipose tissue elicited a stronger cytotoxic response and higher level of insulin resistance in the co-cultured hepatocytes. In conclusion, our results reveal depot-dependent effects of ATEs on co-cultured primary hepatocytes, which in part may be related to a more pronounced infiltration of stromal vascular cells (SVCs, particularly macrophages, in inguinal adipose tissue resulting in stronger responses in terms of hepatotoxicity and insulin-resistance.

    Lipid droplets are ubiquitous organelles that are among the basic building blocks of eukaryotic cells. Despite central roles for cholesterol homeostasis and lipid metabolism, their function and protein composition are poorly understood. Results: We purified lipid droplets from Drosophila embryos and analyzed the associated proteins by capillary LC-MS-MS. Important functional groups include enzymes involved in lipid metabolism, signaling molecules, and proteins related to membrane trafficking. Unexpectedly, histones H2A, H2Av, and H2B were present. Using biochemistry, genetics, real-time imaging, and cell biology, we confirm that roughly 50% of certain embryonic histones are physically attached to lipid droplets, a localization conserved in other fly species. Histone association with droplets starts during oogenesis and is prominent in early embryos, but it is undetectable in later stages or in cultured cells. Histones on droplets are not irreversibly trapped; quantitation of droplet histone levels and transplantation experiments suggest that histones are transferred from droplets to nuclei as development proceeds. When this maternal store of histones is unavailable because lipid droplets are mislocalized, zygotic histone production starts prematurely. Conclusions: Because we uncover a striking proteomic similarity of Drosophila droplets to mammalian lipid droplets, Drosophila likely provides a good model for understanding droplet function in general. Our analysis also reveals a new function for these organelles; the massive nature of histone association with droplets and its developmental time-course suggest that droplets sequester maternally provided proteins until they are needed. We propose that lipid droplets can serve as transient storage depots for proteins that lack appropriate binding partners in the cell. Such sequestration may provide a general cellular strategy for handling excess proteins.

    Schizophrenia is one of the most expensive psychiatric conditions because of high direct and indirect costs associated with the nature of the illness, its resistance to treatment and the consequences of relapse. Long-acting risperidone is a new formulation of an atypical antipsychotic drug that also offers the improvements in compliance associated with haloperidol depot. The aim of this simulation study was to compare the benefits and costs of three pharmacological treatment strategies comprising first-line treatment with long-acting risperidone injection, a haloperidol depot or an oral atypical antipsychotic agent, over a 5-year period in Germany. A discrete event simulation model was developed to compare three treatment scenarios from the perspective of major third-party payers (sickness funds and social security 'Sozialversicherung'). The scenarios comprised first-line treatment with haloperidol depot (scenario 1), long-acting risperidone (scenario 2) and oral olanzapine (scenario 3). Switches to second or third-line options were allowed when side-effects occurred or a patient suffered more than a fixed number of relapses. The model accounted for fixed patient characteristics, and on the basis of these, simulated patient histories according to several time-dependent variables. The time horizon for this model was limited to 5 years, and in accordance with German guidelines, costs and effects were discounted by between 3 and 10%. Direct costs included medication, type of physician visits and treatment location. Indirect costs were not included. Information on treatment alternatives, transition probabilities, model structure and healthcare utilization were derived from the literature and an expert panel. Outcomes were expressed in terms of the number and duration of psychotic episodes, cumulative symptom scores, costs, and quality-adjusted life-years (QALY). Univariate sensitivity analyses were carried out, as were subgroup analyses based on disease severity and

    To evaluate the effects of timing of depot medroxyprogesterone acetate injection on medical abortion outcome and risk of repeat pregnancy within the subsequent 6 months. In a multinational randomized trial, we assigned women undergoing medical abortion who wanted depot medroxyprogesterone acetate to administration either with mifepristone (Quickstart group) or after the abortion (Afterstart group). We ascertained abortion outcome, pregnancies, and contraception use over 7 months. From August 2013 to March 2015, we enrolled 461 participants with pregnancy durations of 75 days or less. Of participants included in the abortion outcome analyses, 14 of 220 (6.4%) and 12 of 226 (5.3%) in the Quickstart and Afterstart groups, respectively, had surgery to complete the abortion; the upper 90% confidence limit on this difference was 4.9%, within our prestipulated 5% noninferiority margin. Ongoing pregnancy after initial abortion treatment was significantly more common in the Quickstart group (8/220 [3.6%]) than in the Afterstart group (2/226 [0.9%]); the difference was 2.7% (90% confidence interval 0.4-5.6%). By 6 months, 5 of 213 (2.3%) and 7 of 217 (3.2%) in the Quickstart and Afterstart groups, respectively, became pregnant (exact log-rank test, P=.64). Use of highly effective contraceptives was significantly more common in the Quickstart group at 31 days (P<.001), but no difference was apparent at 6 months. The Quickstart group was significantly more satisfied with group assignment. Depot medroxyprogesterone acetate administration with mifepristone did not appreciably increase the risk of surgery after medical abortion but did increase the risk of ongoing pregnancy. It enhanced patient satisfaction, but we found no evidence that it decreased 6-month risk of repeat pregnancy. ClinicalTrials.gov, https://clinicaltrials.gov, NCT01902485.

    The release requirements for vaccine antigens delivered by adjuvants with presumed depot function are poorly understood. Water-in-oil (W/O) emulsions are routinely used in many poultry vaccines. They strongly activate antibody production, and are regarded as a depot from which antigens are slowly released, resulting in prolonged antigen residence. However, from earlier studies we concluded that W/O adjuvant activity is partly based on the immunostimulatory activity of the oil phase. Here we assess the dose and regimen requirements for viral antigen in immunization experiments in chickens. Three-week-old to 4-week-old White Leghorn chickens were repeatedly injected with inactivated infectious bursal disease virus antigen over 48 days. Our aim was to compare the antibody responses in repeatedly injected animals, receiving fractioned doses of antigen, with the responses in animals receiving only one injection of the full dose of antigen formulated in either a W/O emulsion or in saline. We observed that repeated administration of small amounts of antigen results in a gradual increase of specific humoral immune responses during the immunization regimen. Immunization with a higher first dose evoked an early higher antibody response, which, however, reached a similar plateau level at the end of the regimen. When compared with lower first-dose regimens, a slow decline of serum antibody titre 2 weeks after the end of antigen injections indicated that repeated injection of small doses of antigen indeed mimics the efficacy of depot-forming adjuvants. All regimens of fractioned antigen in saline, however, proved less effective, when compared with a single-dose vaccination of the cumulative amount of antigen formulated in a W/O emulsion. From our data we confirm that W/O emulsions are very effective vaccine vehicles for improving antigen-specific humoral responses in chickens, owing to a combination of antigen residence-prolonging activity and direct immune stimulation.

    The Chemical Hazard Warning System (CHAWS) is designed to collect meteorological data and to display, in real time, the dispersion of hazardous chemicals that may result from an accidental release. Meteorological sensors have been placed strategically around the Lexington-Blue Grass Army Depot and are used to calculate direction and hazard distance for the release. Based on these data, arrows depicting the release direction and distance traveled are graphically displayed on a computer screen showing a site map of the facility. The objectives of CHAWS are as follows: To determine the trajectory of the center of mass of released material from the measured wind field; to calculate the dispersion of the released material based on the measured lateral turbulence intensity (sigma theta); to determine the height of the mixing zone by measurement of the inversion height and wind profiles up to an altitude of about 1 km at sites that have SODAR units installed; to archive meteorological data for potential use in climatological descriptions for emergency planning; to archive air-quality data for preparation of compliance reports; and to provide access to the data for near real time hazard analysis purposes. CHAWS sites are located at the Pine Bluff Arsenal, Arkansas, Edgewood area of Aberdeen Proving Ground, Maryland, Tooele Depot, Utah, Lexington-Blue Grass Depot, Kentucky, and Johnston Island in the Pacific. The systems vary between sites with different features and various types of hardware. The basic system, however, is the same. Nonetheless, we have tailored the manuals to the equipment found at each site.

    Compliance is often partial with oral antipsychotics and underestimated for patients with serious mental illness. Despite their demonstrated advantages in terms of relapse prevention, depot formulations are still poorly used in routine. As part of a process to improve the quality of care, French Association for Biological Psychiatry and Neuropsychopharmacology (AFPBN) Task Force elaborated a Formal Consensus for the prescription of depot antipsychotics in clinical practice. The Task Force recommends as first-line choice, the use of long-acting injectable (LAI) second-generation antipsychotics in patients with schizophrenia, schizoaffective disorder and delusional disorder. They can be considered as a second-line option as a monotherapy to prevent manic recurrence or in combination with mood stabilizer to prevent depressive recurrence in the maintenance treatment of bipolar disorder. LAI second-generation antipsychotics can also be used after a first episode of schizophrenia. Depot neuroleptics are not recommended during the early course of schizophrenia and are not appropriate in bipolar disorder. They are considered as a second-line option for maintenance treatment in schizophrenia. LAI formulations should be systematically proposed to any patients for whom maintenance antipsychotic treatment is indicated. LAI antipsychotics can be used preferentially for non-compliant patients with frequent relapses or aggressive behaviors. A specific information concerning the advantages and inconveniences of the LAI formulations, in the framework of shared-decision making must be delivered to each patient. Recommendations for switching from one oral/LAI form to another LAI and for using LAI antipsychotics in specific populations (pregnant women, elderly patients, subjects in a precarious situation, and subjects having to be treated in a prison establishment) are also proposed.

    2011-01-01

    Full Text Available Adipose tissue metabolism is closely linked to insulin resistance, and differential fat distributions are associated with disorders like hypertension, diabetes, and cardiovascular disease. Adipose tissues vary in their impact on metabolic risk due to diverse gene expression profiles, leading to differences in lipolysis and in the production and release of adipokines and cytokines, thereby affecting the function of other tissues. In this paper, the roles of the various adipose tissues in obesity are summarized, with particular focus on mitochondrial function. In addition, we discuss how a functionally mitochondrial-targeted compound, the modified fatty acid tetradecylthioacetic acid (TTA, can influence mitochondrial function and decrease the size of specific fat depots.

    Full Text Available This paper presents a multiobjective ant colony algorithm for the Multi-Depot Vehicle Routing Problem with Backhauls (MDVRPB where three objectives of traveled distance, traveling times and total consumption of energy are minimized. An ant colony algorithm is proposed to solve the MDVRPB. The solution scheme allows one to find a set of ordered solutions in Pareto fronts by considering the concept of dominance. The effectiveness of the proposed approach is examined by considering a set of instances adapted from the literature. The computational results show high quality results within short computing times.

    Selection of stable reference genes (REF) is important in real-time PCR data normalization. Bovine tissues such as the mammary gland, liver, muscle, and s.c. fat from the tail head have been thoroughly explored for stable REF, whereas fewer reports exist for other fat depots. Therefore, a suitable combination of REF was tested for different tissues of dairy cattle. Holstein dairy heifers (n = 25) were supplemented (100 g/d) with a control fat (n = 15) without conjugated linoleic acids or with rumen-protected conjugated linoleic acids (n = 10) from the day of calving until slaughter at 1, 42, or 105 d postpartum (n = 5, 10, and 10, respectively). Samples from 6 fat depots (omental, mesenterial, retroperitoneal, s.c. tail head, s.c. withers, and s.c. sternum), liver, semitendinosus muscle, and mammary gland were collected. The REF mRNA were quantified and their stability was analyzed using geNorm(plus). The 3 most stable REF in individual fat tissues and muscle were EMD (emerin), POLR2A (RNA polymerase II), and LRP10 (lipoprotein receptor-related protein 10); in mammary gland were MARVELD1 (marvel domain containing 1), EMD, and LRP10; and in liver were HPCAL1 (hippocalcin-like 1), LRP10, and EIF3K (Eukaryotic translation initiation factor 3). The 3 most stable REF in s.c. fat were EMD, LRP10, and EIF3K; in visceral fat were POLR2A, LRP10, and MARVELD1; and for all 6 adipose tissues were LRP10, EIF3K, and MARVELD1. When the mammary gland was added to the 6 adipose depots, at least 5 REF (LRP10, POLR2A, EIF3K, MARVELD1, and HPCAL1) were needed to reach the threshold of 0.15. Addition of liver to the above-mentioned tissues increased the V value. The data improve the comparison of gene expression between different fat depots. In each case, GAPDH had the lowest stability value.

    Using a coulometric technique based upon the anodic intentiostatic dissolution, we studied the potentiostatic, deposition of nickel, iron and nickel iron alloys. We have shown that the minimum of the curve I = f (t) (deposition current versus time) is probably due to the transitory blocking of the surface by hydrogen and that the syn-crystallisation of nickel and iron is responsible for the anomalous co-deposition of these two elements.

    Full Text Available Adipocytes mainly function as energy storage and endocrine cells. Adipose tissues showed the biological and genetic difference based on their depots. The difference of adipocytes between depots might be influenced by the inherent genetic programing for adipogenesis. We used RNA-seq technique to investigate the transcriptomes in 3 adipose tissues of omental (O, subcutaneous (S and intramuscular (I fats in cattle. Sequence reads were obtained from Illumina HiSeq2000 and mapped to the bovine genome using Tophat2. Differentially expressed genes (DEG between adipose tissues were detected by EdgeR. We identified 5797, 2156, and 5455 DEGs in the comparison between OI, OS, and IS respectively and also found 5657 DEGs in the comparison between the intramuscular and the combined omental and subcutaneous fats (C (FDR<0.01. Depot specifically up- and down- regulated DEGs were 853 in S, 48 in I, and 979 in O. The numbers of DEGs and functional annotation studies suggested that I had the different genetic profile compared to other two adipose tissues. In I, DEGs involved in the developmental process (eg. EGR2, FAS, and KLF7 were up-regulated and those in the immune system process were down-regulated. Many DEGs from the adipose tissues were enriched in the various GO terms of developmental process and KEGG pathway analysis showed that the ECM-receptor interaction was one of commonly enriched pathways in all of the 3 adipose tissues and also functioned as a sub-pathway of other enriched pathways. However, genes involved in the ECM-receptor interaction were differentially regulated depending on the depots. Collagens, main ECM constituents, were significantly up-regulated in S and integrins, transmembrane receptors, were up-regulated in I. Different laminins were up-regulated in the different depots. This comparative transcriptome analysis of three adipose tissues suggested that the interactions between ECM components and transmembrane receptors of fat cells

    Full Text Available Background & aim: Sexual health is an essential element of quality of life, affecting both physical and psychological domains. Hormones used in contraceptive methods have contradictory effects on sexual function. In this study, we aimed to compare sexual function in women using combined oral contraceptives (COC and depot medroxyprogesterone acetate (DMPA, referred to healthcare centers affiliated to Shahid Beheshti University of Medical Sciences in Tehran, Iran in 2013. Methods: This descriptive, comparative study was performed on 240 women (n=120 per group, selected through multistage sampling in Tehran, Iran. A questionnaire consisting of three parts, General Health Questionnaire (GHQ-28, demographic characteristics, and Female Sexual Function Index (FSFI, was completed through interviews. For data analysis, descriptive statistics were calculated, and independent t-test, Mann-Whitney test, Chi-square, and Fisher's exact test were performed, using SPPS version 16. P-value less than 0.05 was considered statistically significant. Results: The mean age at marriage in women using DMPA was lower than those using COC (18.55±3.61 vs. 19.92±3.98 years. Based on the findings, the menstrual status in the majority of DMPA users was irregular (46.7% in DMPA group vs. 8.3% in COC group. The difference in sexual function between the COC and DMPA groups was significant. Sexual arousal and lubrication were more favorable in the COC group in comparison with the DMPA group; also, pain in this group was lower than the DMPA group. Scores of total sexual function (27.35±5.22 in DMPA group vs. 29.15±6.13 in COC group, sexual arousal (4.11±0.90 in DMPA group vs. 4.51±1.39 in COC group, and vaginal lubrication (4.82±1.30 in DMPA group vs. 5.26±1.35 in COC group were lower in the DMPA group, compared to the COC group. Pain scores (4.91±1.25 in DMPA group vs. 5.28±1.19 in COC group were higher in the DMPA group in comparison with the COC group (P

    Background Depot medroxyprogesterone acetate (DMPA) as a hormonal contraceptive is highly effective and widely used,but it may reduce bone mineral density (BMD) and increase the risk of osteoporosis.We compared BMD between users of intramuscular DMPA and nonhormonal subjects.Methods The study included 102 women aged between 16 and 18 years using DMPA for 24 months and 97 women aged between 16 and 18 years using nonhormonal contraception as nonusers control group.BMD of the lumbar spine and femoral neck was measured every 12 months for 24 months using dual-energy X-ray absorptiometry,comparing mean BMD changes in DMPA users and nonusers.Results There were no significant differences between groups at baseline in age,gynecologic age,body mass index (BMI),lumbar spine BMD and femoral neck BMD,etc.At 24 months of DMPA treatment,the mean percentage change from baseline in lumbar spine and femoral neck BMD values had decreased by 1.88% and 2.32%,respectively.The mean lumbar spine and femoral neck BMD in DMPA group at 24 months were not significantly different compared to baseline (P=-0.212 and P=0.106,respectively).In comparison,in nonhormonal control group,there was a trend toward increasing BMD.At 24 months of observation,the mean percentage change from baseline in lumbar spine and femoral neck BMD had increased by 2.08% and 1.46%,respectively.There were no significant difference compared to baseline (P=-0.160 and P=-0.288,respectively).Mean BMD at the spine and femoral neck did not differ significantly between DMPA users and nonusers over 12-month,but the BMD values at both anatomical sites were significantly lower in DMPA users compared with nonusers after 24-month treatment (P=-0.009 and P=-0.009,respectively).Conclusion The evidence of our study suggested that the use of DMPA for short-term (<12-month) has no significant effects on BMD at spine and femoral neck,but long-term exposure to DMPA may prevent the bone mass accrual in adolescents.

    Recently, dramatic progress has been achieved in expanding the sensitivity, resolution, mass accuracy, and scan rate of mass spectrometers able to fragment and identify peptides through MS/MS. Unfortunately, this enhanced ability to acquire proteomic data has not been accompanied by a concomitant increase in the availability of flexible tools allowing users to rapidly assimilate, explore, and analyze this data and adapt to various experimental workflows with minimal user intervention. Here we fill this critical gap by providing a flexible relational database called PeptideDepot for organization of expansive proteomic data sets, collation of proteomic data with available protein information resources, and visual comparison of multiple quantitative proteomic experiments. Our software design, built upon the synergistic combination of a MySQL database for safe warehousing of proteomic data with a FileMaker-driven graphical user interface for flexible adaptation to diverse workflows, enables proteomic end-users to directly tailor the presentation of proteomic data to the unique analysis requirements of the individual proteomics lab. PeptideDepot may be deployed as an independent software tool or integrated directly with our high throughput autonomous proteomic pipeline used in the automated acquisition and post-acquisition analysis of proteomic data.

    Full Text Available Due to the high incidence and severity of obesity and its related disorders, it is highly desirable to develop new strategies to treat or even to prevent its development. We have previously described that Ginkgo biloba extract (GbE improved insulin resistance and reduced body weight gain of obese rats. In the present study we aimed to evaluate the effect of GbE on both inflammatory cascade and insulin signaling in retroperitoneal fat depot of diet-induced obese rats. Rats were fed with high fat diet for 2 months and thereafter treated for 14 days with 500 mg/kg of GbE. Rats were then euthanized and samples from retroperitoneal fat depot were used for western blotting, RT-PCR, and ELISA experiments. The GbE treatment promoted a significant reduction on both food/energy intake and body weight gain in comparison to the nontreated obese rats. In addition, a significant increase of both Adipo R1 and IL-10 gene expressions and IR and Akt phosphorylation was also observed, while NF-κB p65 phosphorylation and TNF-α levels were significantly reduced. Our data suggest that GbE might have potential as a therapy to treat obesity-related metabolic diseases, with special interest to treat obese subjects resistant to adhere to a nutritional education program.

This increase in ovarium MDA was significantly (P<0.05 attenuated by medium dose treatments of combined vitamins C and E. DMPA insignificantly decreased SOD levels compared to the untreated group. This decrease in ovarian SOD level was significantly attenuated by all doses of the combined vitamins C and E. In conclusion, DMPA induces ovarian oxidative stress. Combined vitamins C and E prohibit the increase in ovarian lipid peroxidation, at least in part by modulating of superoxide dismutase. Therefore, this may provide an antioxidant therapy for attenuating the ovarian toxicity found in the DMPA therapy.

    Multifunctional peptide oxytocin currently undergoes intensive research due to its proposed anti-obesity properties. Until now, little is known about regulation of oxytocin receptor in metabolically active tissues in obesity. The aim of the present study was to measure expression of oxytocin receptor upon obese phenotype with respect to the variety among adipose tissue and skeletal muscles with distinct anatomical localisation. Total homogenates were prepared from epididymal, retroperitoneal and inguinal adipose tissues as well as quadriceps and soleus muscle from lean and obese Zucker rats. Oxytocin receptor protein was determined by immunoblot. Interestingly, elevated oxytocin receptor was observed in epididymal adipose tissue of obese rats in contrast to its downregulation in subcutaneous and no change in retroperitoneal fat. In lean animals, oxytocin receptor protein was expressed at similar levels in all adipose depots. This uniformity was not observed in the case of skeletal muscle in which fibre type composition seems to be determinant of oxytocin receptor expression. Quadriceps muscle with the predominance of glycolytic fibres exhibits higher oxytocin receptor expression than almost exclusively oxidative soleus muscle. Oxytocin receptor protein levels were decreased in both skeletal muscles analysed upon obese phenotype. The present work demonstrates that even under identical endocrine circumstances, oxytocin receptor is differentially regulated in adipose tissue of obese rats depending on fat depot localisation. These results also imply which tissues may be preferentially targeted by oxytocin treatment in metabolic disease.

    Adipose tissue represents a complex tissue both in terms of its cellular composition, as it includes mature adipocytes and the various cell types comprising the stromal-vascular fraction (SVF), and in relation to the distinct biochemical, morphological and functional characteristics according to its anatomical location. Herein, we have characterized the proteomic profile of both mature adipocyte and SVF from human visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) fat depots in order to unveil differences in the expression of proteins which may underlie the distinct association of VAT and SAT to several pathologies. Specifically, 24 proteins were observed to be differentially expressed between SAT SVF versus VAT SVF from lean individuals. Immunoblotting and RT-PCR analysis confirmed the differential regulation of the nuclear envelope proteins lamin A/C, the membrane-cytoskeletal linker ezrin and the enzyme involved in retinoic acid production, aldehyde dehydrogenase 1A2, in the two fat depots. In sum, the observation that proteins with important cell functions are differentially distributed between VAT and SAT and their characterization as components of SVF or mature adipocytes pave the way for future research on the molecular basis underlying diverse adipose tissue-related pathologies such as metabolic syndrome or lipodystrophy.

    Full Text Available Objectives. (1 To examine depot-specific PGE2 and PGF2α release and mRNA expression of enzymes or receptors involved in PG synthesis or signaling in human adipose tissues; (2 to identify changes in expression of these transcripts through preadipocyte differentiation; and (3 to examine associations between adipose tissue mRNA expression of these transcripts and adiposity measurements. Methods. Fat samples were obtained surgically in women. PGE2 and PGF2α release by preadipocytes and adipose tissue explants was measured. Expression levels of mRNA coding for enzymes or receptors involved in PG synthesis or signaling were measured by RT-PCR. Results. Cultured preadipocytes and explants from omental fat released more PGE2 and PGF2α than those from the subcutaneous depot and the corresponding transcripts showed consistent depot differences. Following preadipocyte differentiation, expression of PLA2G16 and PTGER3 mRNA was significantly increased whereas COX-1, COX-2, PTGIS, and PTGES mRNA abundance were decreased in both compartments (P≤0.01 for all. Transcripts that were stimulated during adipogenesis were those that correlated best with adiposity measurements. Conclusion. Cells from the omental fat compartment release more PGE2 and PGF2α than those from the subcutaneous depot. Obesity modulates expression of PG-synthesizing enzymes and PG receptors which likely occurs through adipogenesis-induced changes in expression of these transcripts.

    Full Text Available Abstract Background Mast cells are implicated in the pathogenesis of obesity and insulin resistance. Here, we explored the effects of leptin deficiency-induced obesity on the density of mast cells in metabolic (abdominal fat depots, skeletal muscle, and liver and lymphatic (abdominal lymph nodes, spleen, and thymus organs. Fourteen-week-old male leptin-deficient ob/ob mice and their controls fed a standard chow were studied. Tissue sections were stained with toluidine blue to determine the density of mast cells. CD117/c-kit protein expression analysis was also carried out. Furthermore, mast cells containing immunoreactive tumor necrosis factor-α (TNF-α, a proinflammatory cytokine involved in obesity-linked insulin resistance, were identified by immunostaining. Results ob/ob mice demonstrated adiposity and insulin resistance. In abdominal fat depots, mast cells were distributed differentially. While most prevalent in subcutaneous fat in controls, mast cells were most abundant in epididymal fat in ob/ob mice. Leptin deficiency-induced obesity was accompanied by a 20-fold increase in the density of mast cells in epididymal fat, but a 13-fold decrease in subcutaneous fat. This finding was confirmed by CD117/c-kit protein expression analysis. Furthermore, we found that a subset of mast cells in epididymal and subcutaneous fat were immunoreactive for TNF-α. The proportion of mast cells immunoreactive for TNF-α was higher in epididymal than in subcutaneous fat in both ob/ob and control mice. Mast cells were also distributed differentially in retroperitoneal, mesenteric, and inguinal lymph nodes. In both ob/ob mice and lean controls, mast cells were more prevalent in retroperitoneal than in mesenteric and inguinal lymph nodes. Leptin deficiency-induced obesity was accompanied by increased mast cell density in all lymph node stations examined. No significant difference in the density of mast cells in skeletal muscle, liver, spleen, and thymus was

    Is use of depot medroxyprogesterone acetate (DMPA) a risk factor for or a protective factor against prevalent uterine leiomyoma? Ever use of DMPA was associated with a decreased risk (adjusted risk ratio (RR): 0.8, 95% confidence interval (CI): 0.6, 0.9) of prevalent leiomyoma in young African American women. Although progesterone is associated with growth of leiomyoma, previous epidemiological studies have shown a protective association for DMPA use. These previous studies may have been biased by studying clinically diagnosed leiomyoma (DMPA may mask symptoms thus delaying diagnoses). Cross sectional analysis of baseline data from a cohort study of 1696 African American women. Community-based recruitment (e.g. letters, flyers, radio and TV announcements) were used to enroll African American women between 23 and 34 years old without a previous diagnosis of leiomyoma in the Metropolitan Detroit area. Extensive questionnaire data were used to determine DMPA use and screening ultrasound detected the presence of leiomyoma ≥0.5 cm in diameter. Relative risks with adjustment for covariates were calculated for the presence of leiomyoma based on ever use of DMPA as well as duration and recency of use. Among the 1696 volunteers who enrolled, 43% had used DMPA. Leiomyoma were detected in 17% of those who had ever used DMPA compared with 26% of those who had never used DMPA. The reduction in prevalence remained after adjustment for potential confounders and was highest among women who had used DMPA for more than 4 years (adjusted RR: 0.5, 95% CI: 0.3, 0.8). The reduction in risk was seen for women whose most recent use was up to 8 years prior to study enrollment. The use of cross-sectional data means that the timing of initial fibroid development is not known, so the temporality of the association is uncertain. However in this sample of young women, most fibroids were small, suggesting that DMPA exposure may have occurred before leiomyoma development. Our findings are in

    Depot medroxyprogesterone acetate (DMPA) contraception is widely used all over the world; however, it may lead to a decrease in high-density lipoproteins and an increase in low-density lipoproteins (LDL) and triglycerides. These changes in lipid profile have a direct effect on cardiovascular disease risk. This study has been conducted to investigate the relationship between DMPA use and lipid profile, and the effect of worsening of lipid profile on fasting blood glucose. The objective of the present study is to ascertain the effects of DMPA on lipid profiles and Castelli indices, and to estimate the risk of cardiovascular disease in the women using progesterone-only methods for contraception. This was a multicenter case-control study including females of reproductive age. A total of 893 women were selected according to inclusion and exclusion criteria described below with the age range of 19-49 years. Among these, 477 were females who were beginning DMPA for contraception whereas 416 were the matched controls of same age and socioeconomic status. The lipid profiles, Castelli indices and fasting blood sugar were evaluated before initiation of DMPA and thereafter at 3, 6, 9 and 12 months. Controls were also analyzed for the same parameters in the same manner as that of treated group. The results were analyzed by repeated measure analysis of variance followed by Tukey׳s post hoc test for the multiple comparisons. The results showed statistically significant differences in all parameters of lipid profile, namely cholesterol (180.7 ± 38.8 versus 133.03 ± 14.8mg/dL, and P = 0.000), LDL (120.04 ± 36.2 versus 94.27 ± 19.6mg/dL, and P = 0.000), very low-density lipoprotein cholesterol (24.6 ± 10.0 versus 20.99 ± 8.66mg/dL, and P = 0.000), high-density lipoprotein (39.67 ± 3.6 versus 44.13 ± 4.22mg/dL, and P = 0.000), total cholesterol (713.05 ± 110.2 versus 569.19 ± 80.4mg/dL, and P = 0.000), triglycerides (126.33 ± 48.8 versus 99.03 ± 30.6mg/dL, and P = 0

    Results of a study on the metabolic side-effects of depot-medroxyprogesterone acetate (DMPA) in undernourished lactating women, compared with non-lactating women, in three centres in India and Thailand are reported. Analysis of the data on anthropometric and biochemical parameters at the time of recruitment indicated that the lactating women were lighter and had lower plasma glucose and triglyceride levels and a higher alkaline phosphatase activity. Serum cholesterol levels tended to be higher during the first six months of lactation. Use of DMPA over a period of one year was not associated with any alteration in glucose tolerance and in the serum triglyceride, total protein and albumin levels. The observed fall in the cholesterol level and alkaline phosphatase activity in DMPA users might be attributed to waning lactation. PMID:3490928

    Concerns that the injectable contraceptive depot-medroxyprogesterone acetate (DMPA) may increase the risk of HIV acquisition in women led to questions on whether DMPA could reduce efficacy of pre-exposure prophylaxis (PrEP) for HIV prevention. We used a macaque model to investigate the impact of prolonged DMPA exposure on PrEP with emtricitabine/tenofovir disoproxil fumarate. Twelve pigtail macaques treated with DMPA were exposed vaginally to simian HIV once a week for up to 5 months and received either placebo (n = 6) or emtricitabine/tenofovir disoproxil fumarate (n = 6). All control macaques were infected, whereas the PrEP-treated animals remained protected (P = 0.0007). This model suggests that women using DMPA will fully benefit from PrEP.

    Full Text Available In this paper we propose two cooperation schemes to compose new parallel variants of the Variable Neighborhood Search (VNS. On the one hand, a coarse-grained cooperation scheme is introduced which is well suited for being enhanced with a solution warehouse to store and manage the so far best found solutions and a self-adapting mechanism for the most important search parameters. This makes an a priori parameter tuning obsolete. On the other hand, a fine-grained scheme was designed to reproduce the successful properties of the sequential VNS. In combination with the use of parallel exploration threads all of the best solutions and 11 out of 20 new best solutions for the Multi Depot Vehicle Routing Problem with Time Windows were found.

    Although recent advances in synthetic biology allow us to produce biological designs more efficiently than ever, our ability to predict the end result of these designs is still nascent. Predictive models require large amounts of high-quality data to be parametrized and tested, which are not generally available. Here, we present the Experiment Data Depot (EDD), an online tool designed as a repository of experimental data and metadata. EDD provides a convenient way to upload a variety of data types, visualize these data, and export them in a standardized fashion for use with predictive algorithms. In this paper, we describe EDD and showcase its utility for three different use cases: storage of characterized synthetic biology parts, leveraging proteomics data to improve biofuel yield, and the use of extracellular metabolite concentrations to predict intracellular metabolic fluxes.

    According to the Developmental Origin of Health and Disease (DOHaD) concept, maternal obesity and accelerated growth in neonates predispose offspring to white adipose tissue (WAT) accumulation. In rodents, adipogenesis mainly develops during lactation. The mechanisms underlying the phenomenon known as developmental programming remain elusive. We previously reported that adult rat offspring from high-fat diet-fed dams (called HF) exhibited hypertrophic adipocyte, hyperleptinemia and increased leptin mRNA levels in a depot-specific manner. We hypothesized that leptin upregulation occurs via epigenetic malprogramming, which takes place early during development of WAT. As a first step, we identified in silico two potential enhancers located upstream and downstream of the leptin transcription start site that exhibit strong dynamic epigenomic remodeling during adipocyte differentiation. We then focused on epigenetic modifications (methylation, hydroxymethylation, and histone modifications) of the promoter and the two potential enhancers regulating leptin gene expression in perirenal (pWAT) and inguinal (iWAT) fat pads of HF offspring during lactation (postnatal days 12 (PND12) and 21 (PND21)) and in adulthood. PND12 is an active period for epigenomic remodeling in both deposits especially in the upstream enhancer, consistent with leptin gene induction during adipogenesis. Unlike iWAT, some of these epigenetic marks were still observable in pWAT of weaned HF offspring. Retained marks were only visible in pWAT of 9-month-old HF rats that showed a persistent "expandable" phenotype. Consistent with the DOHaD hypothesis, persistent epigenetic remodeling occurs at regulatory regions especially within intergenic sequences, linked to higher leptin gene expression in adult HF offspring in a depot-specific manner.

    The Umatilla Depot Activity (UMDA) near Hermiston, Oregon, is one of eight US Army installations in the continental United States where lethal unitary chemical agents and munitions are stored, and where destruction of agents and munitions is proposed under the Chemical Stockpile Disposal Program (CSDP). The chemical agent inventory at UMDA consists of 11.6%, by weight, of the total US stockpile. The destruction of the stockpile is necessary to eliminate the risk to the public from continued storage and to dispose of obsolete and leaking munitions. In 1988 the US Army issued a Final Programmatic Environmental Impact Statement (FPEIS) for the CSDP that identified on-site disposal of agents and munitions as the environmentally preferred alternative (i.e., the alternative with the least potential to cause significant adverse impacts), using a method based on five measures of risk for potential human health and ecosystem/environmental effects; the effectiveness and adequacy of emergency preparedness capabilities also played a key role in the FPEIS selection methodology. In some instances, the FPEIS included generic data and assumptions that were developed to allow a consistent comparison of potential impacts among programmatic alternatives and did not include detailed conditions at each of the eight installations. The purpose of this Phase 1 report is to examine the proposed implementation of on-site disposal at UMDA in light of more recent and more detailed data than those included in the FPEIS. Specifically, this Phase 1 report is intended to either confirm or reject the validity of on-site disposal for the UMDA stockpile. Using the same computation methods as in the FPEIS, new population data were used to compute potential fatalities from hypothetical disposal accidents. Results indicate that onsite disposal is clearly preferable to either continued storage at UMDA or transportation of the UMDA stockpile to another depot for disposal.

    As part of the Chemical Stockpile Disposal Program, an independent review is presented of the US Army Phase I environmental report for the disposal of chemical agents and munitions stored at the Pueblo Depot Activity (PUDA) in Pueblo, Colorado. The Phase I report addresses new and additional concerns not incorporated in the final programmatic environmental impact statement (FPEIS). These concerns are addressed by examining site-specific data for the PUDA. On the basis of our review of the Phase I report, we concluded that on-site meteorological data from December 1988 to June 1992 appear to be of insufficient quality to have been used instead of the off-site Pueblo airport data. No additional meteorological data have been collected since June 1992. The Phase I report briefly mentions problems with the air pollution control system. These problems will likely require the systems to be upgraded at the Johnston Atoll site and at each of the other depots in the continental United States. Without such improvements, the probability of accidents during start-up and shutdown would likely increase. The Army has a lessons-learned program to incorporate improvements into the design of future facilities. The Phase I report does not make any design change commitments. These issues need to be fully evaluated and resolved before any final conclusion concerning the adequacy of the decision in the FPEIS can be made with respect to the PUDA. With the exception of this issue, the inclusion of other more detailed site-specific data in the Phase I report does not change the decision reached in the FPEIS (which favored on-site disposal at the PUDA). We recommend that site-specific data on water, ecological, socioeconomic, and cultural resources and emergency planning and preparedness be considered explicitly in the site-specific EIS decision-making process.

    Incessantly long-term real-time detection of temperature is demanded in weapon depots, where the weapon equipment is stored in, to realize the self-regulation of temperature. Long-Distance intellectualized control can be actualized by setting sensor-net which is composed by several temperature sensors to simultaneously detect multi-point and multi- parameter. The temperature sensors based on Fiber Bragg Grating Technology are more suitable for long-term detection for their preponderance in high sensitivity, small volume, anti-jamming and so on. The temperature sensing system, which is composed by several Fiber Bragg Grating sensors in one light-cable, can accomplish Quasi-Distributed measurement and is suitable for multi-point and multi- parameter detection. Basal principle of Fiber Bragg Grating sensing technology is expounded in the article, with a sensing system applied to the long-distance detection of temperature in the depots is designed based on F-P Scanning Method. Besides, DSP and FPGA are adopted pre-treat the transformed data from AD such as filter and determine threshold. The main modules of this demodulation system such as 1550nm exact photoelectric detection module and trigonal wave voltage scan module are designed in this paper to realize demodulation. Proved by the analysis of the testing data, the Fiber Bragg Grating temperature sensing system, whose testing precision achieved the design purpose, has advantages of real-time measure and long-term stability. The system, which provides guarantee to realize the auto-control of temperature, can be generalized and will provide favorable foundation for the broad using of Fiber Bragg Grating sensing technology in the army.

    An array of feedstock is being evaluated as potential raw material for cellulosic biofuel production. Thorough assessments are required in regional landscape settings before these feedstocks can be cultivated and sustainable management practices can be implemented. On the processing side, a potential solution to the logistical challenges of large biorefi neries is provided by a network of distributed processing facilities called local biomass processing depots. A large-scale cellulosic ethanol industry is likely to emerge soon in the United States. We have the opportunity to influence the sustainability of this emerging industry. The watershed-scale optimized and rearranged landscape design (WORLD) model estimates land allocations for different cellulosic feedstocks at biorefinery scale without displacing current animal nutrition requirements. This model also incorporates a network of the aforementioned depots. An integrated life cycle assessment is then conducted over the unified system of optimized feedstock production, processing, and associated transport operations to evaluate net energy yields (NEYs) and environmental impacts.

    The aim of this audit was to review current practice within a rural mental health service area on the monitoring and documentation of side effects of antipsychotic depot medication. Following a review of the literature on best practice internationally, an evidence based audit tool was adapted. A sample of 60 case files, care plans and prescriptions were audited between January and May 2010. This represented 31% of the total number of service users receiving depot injections in the mental health service region (n=181). The audit results revealed that most service users had an annual documented medical review and a documented prescription. However, only 5 (8%) case notes examined had documentation recorded describing the condition of the injection site and alternation of the injection site was recorded in only 28 (47%) case notes. No case notes examined had written consent to commence treatment recorded, and only 3 (5%) of case notes had documented that information on the depot injection and side effects was given. In 57 (95%) of case notes no documentation of recorded information on the depot and on side effects was given. Documentation of physical observations and tests revealed that 58% of cases had full blood count, liver function tests, thyroid function tests and fasting lipids recorded. All other tests (i.e. temperature, pulse, respirations, blood pressure, ECG) were recorded in less than 50% of cases. Prolactin levels were not recorded in any case. The lack of written consent was partly attributed to lack of recording of consent. The failure to monitor and record some\\r\

    Full Text Available Context Sandostatin® LAR® depot is a synthetic analogue of the naturally occurring hormone somatostatin and is indicated for certain patients with acromegaly and severe diarrhea and flushing episodes associated with metastatic carcinoid tumors and for the long-term treatment of the profuse watery diarrhea associated with VIP-secreting tumors in patients in whom initial treatment with immediate release Sandostatin® injection has been shown to be effective and tolerated. The most common toxicities include biliary disorders, gastrointestinal disorders, injection-site pain, hypoglycemia and hyperglycemia. Rheumatoid arthritis or similar toxicities have not been associated with Sandostatin® LAR® depot. Case report We present a 53-year-old female with a history of neuroendocrine tumor of the pancreas with metastasis to the liver, lung developed joint pains in the hands as well as feet accompanied with intermittent swelling in the morning and pain in the bilateral joints in the hands as well as feet following 45th cycle of Sandostatin® LAR® depot at a dose of 30 mg. All the work-up including rheumatoid factor, anti nuclear antibody, cryoglobulins were within normal limits except her erythrocyte sedimentation rate was elevated. No radiological abnormalities were revealed. Her symptoms improved after we reduced the dose to 20 mg. Discussion Her Naranjo scale was 7, suggesting a probable relation. The patient had four signs and symptoms as required by the American College of Rheumatology for the diagnosis of rheumatoid arthritis. The association of the rheumatoid arthritis with Sandostatin® LAR® depot may be a rare complication but with the extended use beyond acromegaly and carcinoid to acute esophageal variceal bleeding, pancreatic pseudocysts, gastrointestinal, and pancreatic external fistulae, short bowel syndrome, a dumping syndrome and acquired immunodeficiency syndrome-related refractory hypersecretory diarrhea, physicians should be made

    We have demonstrated that among carcass adipose tissue depots, brisket subcutaneous adipose tissue contains the greatest concentration of MUFA and lowest concentration of SFA. Therefore, we hypothesized that brisket subcutaneous adipose tissue depots would exhibit greater adipogenic gene expression over time than other major subcutaneous adipose tissue depots. Four Angus steers, each at 9, 12, 14, and 16 mo of age, were harvested and fresh subcutaneous adipose tissue samples were collected from over the brisket, chuck, rib, loin, sirloin, round, flank, and plate. Relative gene expression for C/EBPβ, PPARγ, carnitine palmitoyltransferase-1 beta (CPT-1β), stearoyl-coenzyme A desaturase (SCD), AMP-activated protein kinase alpha (AMPKα), and G-coupled protein receptor 43 (GPR43) was analyzed by quantitative real-time PCR. Expression of C/EBPβ, PPARγ, and CPT-1β was greatest at 12 to 14 mo of age (all P subcutaneous adipose tissues than in brisket and round adipose tissues. The expression of the SCD gene did not differ among the 4 age groups (P = 0.95). The palmitoleic:stearic acid ratio (an estimate of SCD activity) was greater (P subcutaneous adipose tissues from brisket, plate, and round than in the loin, rib, and sirloin. Conversely, subcutaneous adipose tissue from the loin, rib, and sirloin had greater (P subcutaneous adipose tissues with the highest concentration of MUFA and least SFA consistently exhibited the least SCD gene expression and adipogenic gene expression. We conclude that MUFA in the brisket and other depots with large SCD indices were deposited before 9 mo of age, during a time when the subcutaneous adipocytes were highly differentiated.

    The prevalence of insulin resistance and type 2 diabetes increases with aging and these disorders are associated with inflammation. Insulin resistance and inflammation do not develop at the same time in all tissues. Adipose tissue is one of the tissues where inflammation and insulin resistance are established earlier during aging. Nevertheless, the existence of different fat depots states the possibility of differential roles for these depots in the development of age-associated inflammation and insulin resistance. To explore this, we analyzed insulin signaling and inflammation in epididymal, perirenal, subcutaneous, and brown adipose tissues during aging in Wistar rats. Although all tissues showed signs of inflammation and insulin resistance with aging, epididymal fat was the first to develop signs of inflammation and insulin resistance along aging among white fat tissues. Subcutaneous adipose tissue presented the lowest degree of inflammation and insulin resistance that developed latter with age. Brown adipose tissue also presented latter insulin resistance and inflammation but with lower signs of macrophage infiltration. Caloric restriction ameliorated insulin resistance and inflammation in all tissues, being more effective in subcutaneous and brown adipose tissues. These data demonstrate differential susceptibility of the different adipose depots to the development of age-associated insulin resistance and inflammation. © The Author 2015.

    We previously reported that adenosine monophosphate-activated protein kinase (AMPK) activity is lower in adipose tissue of morbidly obese individuals who are insulin resistant than in comparably obese people who are insulin sensitive. However, the number of patients and parameters studied were small. Here, we compared abdominal subcutaneous, epiploic, and omental fat from 16 morbidly obese individuals classified as insulin sensitive or insulin resistant based on the homeostatic model assessment of insulin resistance. We confirmed that AMPK activity is diminished in the insulin resistant group. A custom PCR array revealed increases in mRNA levels of a wide variety of genes associated with inflammation and decreases in PGC-1α and Nampt in omental fat of the insulin resistant group. In contrast, subcutaneous abdominal fat of the same patients showed increases in PTP-1b, VEGFa, IFNγ, PAI-1, and NOS-2 not observed in omental fat. Only angiotensinogen and CD4+ mRNA levels were increased in both depots. Surprisingly, TNFα was only increased in epiploic fat, which otherwise showed very few changes. Protein carbonyl levels, a measure of oxidative stress, were increased in all depots. Thus, adipose tissues of markedly obese insulin resistant individuals uniformly show decreased AMPK activity and increased oxidative stress compared with insulin sensitive patients. However, most changes in gene expression appear to be depot-specific. PMID:22323564

    The need for quarterly clinic visits is a barrier to use of subcutaneous depot medroxyprogesterone acetate (DMPA-SC) contraception. The ability to self-inject at home may enhance method acceptance. Since efficacy depends on proper administration, we evaluated whether women could correctly perform simulated injections of DMPA-SC in a Uniject™ injection system using printed Instructions for Use (IFU), with and without hands-on training. Adult female volunteers (N=120) injected DMPA-SC into a rubber trainer at two visits, 3 months apart. Women were randomly assigned to receive hands-on training before the first injection or no training. The primary outcome was the proportion of women who successfully operated the injection system. An attempt was defined as successful if the participant correctly performed all critical steps in the injection procedure (getting ready, selecting an injection area, preparing the injector, mixing the medicine, activating the injector, injecting the dose) and expelled the dose without unexpected interruption. The success rate at month 3 was considered the primary endpoint. A one-sided 95% confidence limit >80% was used to declare the delivery system and IFU "fit for purpose." With training, the success rate (one-sided 95% confidence limit) was 90.0% (81.8%) at day 1 and 96.7% (90.4%) at month 3; without training, rates were 76.7% (66.7%) and 88.3% (79.8%), respectively. The trained (96.4%) and untrained (92.2%) groups successfully completed injecting into the trainer at first injection, the final critical step of the injection procedure, despite the fact that about one third of participants considered expelling depot medroxyprogesterone acetate (one component of this step) to be difficult. Most participants understood the IFU and successfully operated the injection system. Initial hands-on training improved success rates at both visits. For women interested in self-injection, providers should review all steps of the IFU, provide a

    Abstract Background: The evaluation of brown adipose tissue (BAT) and its role in metabolism and obesity remains an important topic in the recent literature. This study evaluated the influence of the BAT triglyceride content measured by proton magnetic resonance (MR) spectroscopy in patients with type 2 diabetes mellitus (DM2) and prediabetes on insulin sensitivity. Methods: A total of 25 patients with DM2 and prediabetes (45.9 ± 10.1 years old, body mass index [BMI] of 31.6 ± 5.4 kg/m2) underwent anthropometric measurements (BMI), insulin sensitivity analysis (M value during euglycemic hyperinsulinemic clamp and homeostasis model assessment of insulin resistance), proton MR spectroscopy, and blood tests (total cholesterol, low-density lipoproteins, high-density lipoproteins, and triglycerides). The relationship between the triglyceride content in the supraclavicular fat depot and insulin sensitivity, anthropometric measurements, and blood test results was assessed. Results: The triglyceride content in the supraclavicular fat depot varied between 79.2% and 97.1% (mean: 92.6% ± 4.2%). The triglyceride content in the subcutaneous white adipose tissue of the neck was significantly higher (85.3%–99.3%; mean: 95.5% ± 2.9%; P = 0.0007). The triglyceride content in the supraclavicular fat depot exhibited a significantly moderate correlation with the BMI (r = 0.64; P = 0.0009). A significant weak negative correlation between the supraclavicular fat content and M value was revealed (r = −0.44; P = 0.002). Patients with high insulin resistance (IR) had a higher triglyceride content in the supraclavicular fat depot than patients with normal and lower IR (94.3% ± 2.0% vs. 90.4% ± 5.2%; P = 0.02). Conclusions: Reducing the BAT content in the supraclavicular fat depot can influence the development of IR in patients with DM2 and prediabetes. PMID:28118051

    Smoking has deleterious effects on Pulmonary Function Test (PFT) parameters; however, evidences about recovery in ex-smokers are ambiguous. Therefore present study was conducted to quantify relative deterioration of PFT parameters and to assess reversibility of the same. A cross-sectional study was conducted on 84 bus-depot workers consisting of equal number of smokers, ex-smokers and non-smokers. PFT observations were obtained using Medspiror following standard methods and precautions. Comparisons among three groups were performed employing one-way ANOVA and post-hoc tests. There were substantial effects of smoking on PFT parameters (deterioration was up-to half). Partial recovery was found in all the parameters of ex-smokers. Frequency and duration of smoking were negatively correlated with some of the parameters. In conclusion, present study has demonstrated considerable deterioration of PFT parameters in smokers and indications of recovery in ex-smokers. Further detailed study with larger sample size and stricter definition of ex-smokers is recommended.

    The aim of the study was to assess insulin resistance parameters using successive homeostasis model assessment (HOMA) and clinical evaluations in healthy new users of depot medroxyprogesterone acetate (DMPA). A prospective 12-month study was carried out to compare 31 DMPA users with 25 copper intrauterine device (Cu-IUD; TCu380A) users, matched for age (± 1 year) and body mass index (BMI; ± 1 kg/m(2)). Participants met the following criteria: age 18 to 40 years, BMI 2.7. The DMPA group showed significant increases in BMI, waist circumference, fasting insulin and HOMA-IR throughout the observation period in relation to baseline. Significant increases in BMI and waist circumference were observed in the DMPA group at 12 months compared with the Cu-IUD group. Five DMPA users had abnormal HOMA-IR values, three of whom had gained > 5 kg in weight at 12 months. HOMA-IR represents a useful tool to indicate changes in carbohydrate metabolism in non-obese DMPA users, especially when accompanied by measurement of clinical parameters such as BMI and waist circumference.

    Community-based services (CBS) have long used checklists to determine eligibility for contraceptive method use, in particular for combined oral contraceptives (COCs) and the 3-month injectable contraceptive depot-medroxyprogesterone acetate (DMPA). As safety information changes, however, checklists can quickly become outdated. Inconsistent checklists and eligibility criteria often cause uneven access to contraceptives. In 1996, WHO produced updated eligibility criteria for the use of all contraceptive methods. Based on these criteria, new checklists for COCs and DMPA were developed. This article describes the new checklists and their development. Several rounds of expert review produced checklists that were correct, comprehensible and consistent with the eligibility requirements. Nevertheless, field-testing of the checklists revealed that approximately half (48%) of the respondents felt that one or more questions still needed greater comprehensibility. These findings indicated the need for a checklist guide. In March 2000, WHO convened a meeting of experts to review the medical eligibility criteria for contraceptive use. The article reflects also the resulting updated checklist. PMID:10994285

    Full Text Available Background It seems that depot-medroxyprogesterone acetate (DMPA use can have an effect on a woman’s oral health, and cause periodontal changes in adult women. However, there is little research in this regard and consensus has not been reached in the literature. Objectives This study aimed to investigate the association between DMPA injection and periodontal health in reproductive age women. Materials and Methods This descriptive analytical study was conducted on 194 women aged 20 - 40 years in Ahvaz health care centers, southwest of Iran, during 2015. Ninety-seven women taking DMPA were assigned to the case group and 97 women who did not use DMPA were assigned to the control group. Periodontal parameters such as bleeding on probing, probing pocket depth and clinical attachment loss were measured. Data were analyzed by SPSS software version 19 using descriptive and analytic (Chi-square, Mann-Whitney and student’s t-test statistical methods. Results There was a statistically significant difference regarding bleeding on probing, probing pocket depth and clinical attachment loss between the case and control groups. Totally, 56.7% of the women in the case group had periodontitis compared to 16.5% in the control group (P < 0.0001. Conclusions Based on our findings, the use of DMPA can affect the periodontal health status of women. Therefore, women who use this method must have a strict oral hygiene care program.

    The purpose of this study was to investigate the effects of green tea (GT) on the spiral artery density and endometrial thickness in female rats treated with the depot-medroxyprogesterone acetate (DMPA). A total of 24 female rats were randomly divided into four groups (n = 6 each): The control group (no treatment), the DMPA-treated group, treated with DMPA and GT doses of 165 mg/kg of body weight/day, and treated with DMPA and GT doses of 330 mg/kg of body weight/day. Spiral artery density and endometrial thickness were subjected to histopathological analysis. Spiral artery density decreased in the DMPA-treated group, despite the insignificant difference (P > 0.05). With regard to the administration of GT at doses of 165 and 330 mg/g of body weight/day, only GT at the high dose was capable of significantly preventing a decrease in spiral artery density (P 0.05). Meanwhile, the administration of DMPA and/or DMPA with GT did not cause significant changes in endometrial thickness relative to the control group (P > 0.05). DMPA induced a decrease in spiral artery density, despite the insignificant differences, and these changes could be normalized by the administration of high doses of GT. Therefore, GT could be a candidate herb to prevent the adverse effects of the contraceptive DMPA.

    Background Concomitant use of antiretrovirals (ARV) and hormonal contraceptives may change the metabolism of each and the resulting safety profiles. We evaluated the safety and tolerability of depot medroxyprogesterone acetate (DMPA) among women on ARV. Study Design HIV-infected women on selected ARV regimens or no ARV were administered DMPA 150 mg intramuscularly and evaluated for 12 weeks for adverse events, changes in CD4+ count and HIV RNA levels, and ovulation. Results Seventy evaluable subjects were included, 16 on nucleoside only or no ARV, 21 on nelfinavir-containing regimens, 17 on efavirenz-containing regimens, and 16 on nevirapine-containing regimens. Nine grade 3 or 4 adverse events occurred in 7 subjects; none were judged related to DMPA. The most common findings possibly related to DMPA were abnormal vaginal bleeding (9, 12.7%), headache (3, 4.2%), abdominal pain, mood changes, insomnia, anorexia, and fatigue, each occurring in 2 (2.9%) subjects. No significant changes in CD4+ count or HIV RNA levels occurred with DMPA. No evidence of ovulation was detected, and no pregnancies occurred. Conclusions The clinical profile associated with DMPA administration in HIV-infected women, most on ARV, appears similar to that seen in HIV-uninfected women. DMPA prevented ovulation and did not affect CD4+ counts or HIV RNA levels. In concert with previously published DMPA/ARV interaction data, these data suggest that DMPA can be used safely by HIV-infected women on the ARV studied. PMID:18226670

    With the Oil and Gas Law No. 22 of 2001, national and foreign private enterprises can invest in all sectors of Oil and Gas in Indonesia. In anticipation of this free competition, Pertamina, as a state-owned enterprises, which previously had monopolized the oil and gas business activities in Indonesia, should be able to improve services as well as the efficiency in order to compete in the free market, especially in terms of cost efficiency of fuel distribution to gas station (SPBU). To optimize the distribution activity, it is necessary to design a scheduling system and its fuel delivery routes daily to every SPBU. The determination of routes and scheduling delivery of fuel to the SPBU can be modeled as a Petrol Station Replenishment Problem (PSRP) with the multi-depot, multi-product, time windows and split deliveries, which in this study will be completed by the Tabu Search algorithm (TS). This study was conducted in the area of Bandung, the capital of West Java province, which is a big city and the neighboring city of Jakarta, the capital city of Indonesia. By using the fuel delivery data for one day, the results showed a decrease of 16.38% of the distance of the route compared to the current conditions, which impacted on the reduction of distribution costs and decrease the number of total trips by 5.22% and 3.83%.

  2. Dermal adipocytes and hair cycling: is spatial heterogeneity a characteristic feature of the dermal adipose tissue depot?

    2016-04-01

    Adipocytes are widely distributed in the dermis, in a unique fat depot referred to as dermal white adipose tissue (dWAT). In rodents, dWAT is present as widespread thin layers, whereas in pigs and humans, it is present in clusters referred to as 'dermal cones' around the pilosebaceous units. This distinct layer of fat cells located above the subcutaneous white adipose tissue is important for proper hair follicle (HF) cycling in rodents. Murine HFs produce spatially restricted synchronous patches after their second postnatal cycle which correlates with the spatial heterogeneity of murine dWAT. Similarly, the cycling of HFs in humans may also be related to the spatial distribution of dWAT, making the difference between murine and human HF cycling of more quantitative than of qualitative nature. This should allow the production of small spatially correlated HF patches in human skin, and we propose that this process can be regulated by paracrine signalling involving a number of signalling modules, including the hedgehog pathway. This pathway is an established player in HF cycling, but is also involved in the regulation of adipogenesis and may therefore be a key regulator of the process across species. We also suggest that the spatial heterogeneity of dWAT is connected not only to HF cycling, but may also be related to other physiological and pathological processes in the skin.

    Objectives In a cluster randomised controlled trial, offering financial incentives improved adherence to antipsychotic depot medication over a 1-year period. Yet, it is unknown whether this positive effect is sustained once the incentives stop. Methods and analyses Patients in the intervention and control group were followed up for 2 years after the intervention. Primary and secondary outcomes were assessed at 6 months and 24 months post intervention. Assessments were conducted between September 2011 and November 2014. Results After the intervention period, intervention and control groups did not show any statistically significant differences in adherence, neither in the first 6 months (71% and 77%, respectively) nor in the following 18 months (68%, 74%). There were no statistically significant differences in secondary outcomes, that is, adherence ≥95% and untoward incidents either. Conclusions It may be concluded that incentives to improve adherence to antipsychotic maintenance medication are effective only for as long as they are provided. Once they are stopped, adherence returns to approximately baseline level with no sustained benefit. Trial registration number ISRCTN77769281; Results. PMID:27655261

    Goserelin acetate is a LH-RH agonist developed by AstraZeneca (formerly ICI, UK), and has been used clinically for the treatment of prostate cancer as a 4-week controlled-release formulation (Zoladex 3.6 mg depot). Recently, a new drug (Zoladex LA 10.8 mg depot) with 3-month controlled-release formulation was developed and became commercially available in Japan. In the randomized comparative phase III studies carried out with global bases, single administration of the new drug yielded almost equivalent anti-testosterone effect and the same serum level of the previous 3.6 mg depot formulation in 3-times continuous administration. In these studies, adverse drug reactions, which were mainly due to pharmacological effects of the new drug and minimal, were found in 52.6% (41/78) compared with 54.8% (46/84) with the previous 3.6 mg depot formulation. In the phase III studies, there were no significant differences in average serum testosterone levels between the two formulations at 12 and 13 weeks after administration. In the Japanese late phase II study with untreated patients, castration effect was observed in all 20 cases entered in the trial. In 20 cases in which treatment was switched from 3.6 mg depot to the new formulation, there were no significant changes in serum testosterone levels at castration level of the untreated patients, 90% (18/20) responded to the treatment, and normalization of PSA level was found in 75.0% (15/20). The adverse drug reactions were mainly increased triglyceride level and hot flushes. In the retrospective evaluation of untreated patients in this trial and the post-marketing clinical trial data for 3.6 mg depot, it was concluded that the new drug had almost the same efficacy and safety profile as 3.6 mg depot in Japanese people. These results indicate that Zoladex LA 10.8 mg depot has the same efficacy and safety as 3.6 mg depot with administration every three months, the burden of injection of LH-RH agonist can be reduced.

    Biodegradable polymer-based injectable in situ forming depot (ISD) systems that solidify in the body to form a solid or semisolid reservoir are becoming increasingly attractive as an injectable dosage form for sustained (months to years) parenteral drug delivery. Evaluation of long-term drug release from the ISD systems during the formulation development is laborious and costly. An accelerated release method that can effectively correlate the months to years of long-term release in a short time such as days or weeks is economically needed. However, no such accelerated ISD system release method has been reported in the literature to date. The objective of the current study was to develop a short-term accelerated in vitro release method for contraceptive levonorgestrel (LNG)-containing ISD systems to screen formulations for more than 3-month contraception after a single subcutaneous injection. The LNG-containing ISD formulations were prepared by using biodegradable poly(lactide-co-glycolide) and polylactic acid polymer and solvent mixtures containing N-methyl-2-pyrrolidone and benzyl benzoate or triethyl citrate. Drug release studies were performed under real-time (long-term) conditions (PBS, pH 7.4, 37 °C) and four accelerated (short-term) conditions: (A) PBS, pH 7.4, 50 °C; (B) 25% ethanol in PBS, pH 7.4, 50 °C; (C) 25% ethanol in PBS, 2% Tween 20, pH 7.4, 50 °C; and (D) 25% ethanol in PBS, 2% Tween 20, pH 9, 50 °C. The LNG release profile, including the release mechanism under the accelerated condition D within two weeks, correlated (r² ≥ 0.98) well with that under real-time conditions at four months.

    To evaluate whether contraceptive insurance coverage for women who present for an abortion is associated with obtaining long-acting reversible contraception or depot medroxyprogesterone acetate (DMPA) on the day the abortion is completed. We conducted a prospective cohort study of women presenting for medical or surgical abortion at a single health center in North Carolina. Eligible women were 18 years or older and fluent in English or Spanish. Data were from participant questionnaires, medical charts, and financial records. Our main exposure was whether the woman had insurance coverage for contraception at clinic intake. Our primary outcome was receiving DMPA, an intrauterine device, or a contraceptive subdermal implant on the same day of their surgical abortion or at the visit that determined their medication abortion was complete. We used univariable, bivariable, and multivariable analysis to report our findings. Five hundred seventy-five women enrolled in our cohort between September 2015 and April 2016. One hundred twenty-eight (22%) had insurance coverage and 447 (78%) did not. In the group with insurance coverage for contraception, 38% (49/128) received a long-acting reversible contraception method or DMPA compared with 7% (33/447) in the group without insurance coverage for contraception. After adjusting for confounding, women with contraceptive coverage were more than five times as likely to receive immediate postabortion contraception with one of these methods compared with women without coverage (relative risk 5.6, 95% confidence interval 3.8-8.3). Women with contraceptive insurance coverage on the day of their abortion were more likely to leave the abortion clinic with an intrauterine device or implant in place or receive DMPA injection compared with women without coverage.

    Depot medroxyprogesterone acetate (DMPA) is associated with HIV acquisition. We studied changes in vaginal microbiota and inflammatory milieu after DMPA initiation. In a cohort of HIV-negative Kenyan women, we collected monthly vaginal swabs over 1 year before and after DMPA. Using quantitative polymerase chain reaction, we compared quantities of Lactobacillus crispatus, Lactobacillus jensenii, Lactobacillus iners, Gardnerella vaginalis, and total bacterial load (16S ribosomal RNA gene levels). Six vaginal immune mediators were measured with enzyme-linked immunosorbent assay. Trends in the detection and quantity of bacteria were estimated by logistic and linear mixed-effects regression. From 2010 to 2012, 15 HIV-seronegative women initiated DMPA, contributing 85 visits (median, 6 visits/woman; range, 3-8 visits/woman). The median time of DMPA-exposed follow-up was 8.4 months (range, 1.5-11.6 months). Seven women (46%) had bacterial vaginosis within 70 days before DMPA start. L. iners was detected in 13 women (87%) before DMPA start, but other lactobacilli were rarely detected. Gardnerella vaginalis decreased by 0.21 log10 copies per swab per month after DMPA exposure (P = 0.01). Total bacterial load decreased by 0.08 log10 copies per swab per month of DMPA (P = 0.02). Sustained decreases in interleukin (IL)-6 (P = 0.03), IL-8 (P = 0.04), and IL-1 receptor antagonist (P < 0.001) were also noted. Nine women (60%) had L. crispatus detected post-DMPA, which significantly correlated with reduced IL-6 (P < 0.01) and IL-8 (P = 0.02). Initiation of DMPA led to sustained shifts in vaginal bacterial concentrations and levels of inflammatory mediators. Further studies are warranted to outline components of the vaginal microbiota influenced by DMPA use and impact on HIV susceptibility.

    Hormonal contraception with depot medroxyprogesterone acetate (DMPA) may increase HIV acquisition risk, but observational human studies are inconclusive, and animal models can help investigate this risk. In this study, we test the impact of a low DMPA dose, designed to resemble human contraceptive use, on Simian-Human Immunodeficiency Virus (SHIV) acquisition risk in pigtail macaques (Macaca nemestrina). Macaques metabolize DMPA faster than humans. We previously identified a per-weight DMPA dose and administration frequency that achieves long-lasting suppression of ovulation in macaques. Eight macaques were given 1.5-mg/kg DMPA monthly, whereas 11 were untreated controls. For comparison, women receive 150 mg (approximately 2 mg/kg) every 3 months. We exposed monkeys to 20 suboptimal SHIV challenges, designed to slowly infect half of controls and allow increased infection in the DMPA group. It took a median 5.5 viral challenges to infect DMPA-treated macaques and 9 challenges for controls (P = 0.27; exact conditional logistic regression). The exact odds ratio was 2.2 (CI: 0.6 to 8.3). Ovulation was suppressed, and the vaginal epithelium was thinned after DMPA treatment in all animals (mean, 30 and 219 mm in DMPA-treated and control macaques, respectively, P = 0.03, t test using the Satterthwaite degrees-of-freedom approximation). SHIV infections in DMPA-treated macaques were 2.2 times those of controls, but this was not statistically significant. The result is remarkably similar to studies of human DMPA use, which have shown HIV risk increases of a similar magnitude and of variable significance. Taken together with previous studies of higher DMPA doses in macaques, the results suggest a dose-dependent effect of DMPA on Simian Immunodeficiency Virus (SIV) or SHIV acquisition.

    Purpose To evaluate any association between incidence of osteoporotic fractures and use of depot medroxyprogesterone acetate (DMPA) and/or anti-epileptic drugs (AEDs) among women and girls with developmental disabilities. Methods Cross-sectional population–based observational study of all non-institutionalized females with developmental disabilities age thirteen and older who received fee-for-service Medicaid in Washington State during 2002 (N=6773), using administrative data. Main Findings In a sample of 6,773 females, 140 women (2%) had an osteoporotic fracture during 2002. Among 340 users of DMPA, 13 (3.8%) had an osteoporotic fracture with an odds ratio of 2.4 (CI 95%, 1.3–4.4) for fracture compared to non-users. Among 1909 users of AEDs, 60 (3.1%) had an osteoporotic fracture with an odds ratio of 1.9 (CI 95%, 1.3–2.6) for fracture compared to non-users. We controlled for age and race (as Caucasian or non-Caucasian). Conclusions Use of either AEDs or DMPA by women with developmental disabilities is associated with significantly increased incidence of fracture. Women and girls who have developmental disabilities may be poor candidates for DMPA use due to increased risk of fractures. Further research is indicated (1) to determine the specific risks profile of DMPA for this population, (2) to explore alternative means of managing significant menstrual problems and contraceptive needs in this population and (3) to screen current and previous users of DMPA and chronic users of AEDs for osteoporosis risk, regardless of age.

    The effects of sex hormones on the immune defenses of the female genital mucosa and its susceptibility to infections are poorly understood. The injectable hormonal contraceptive depot medroxyprogesterone acetate (DMPA) may increase the risk for HIV-1 acquisition. We assessed the local concentration in the female genital mucosa of cationic polypeptides with reported antiviral activity in relation to DMPA use. HIV-1-uninfected women were recruited from among couples testing for HIV in Nairobi, Kenya. Cervicovaginal secretion samples were collected, and the concentrations of HNP1-3, LL-37, lactoferrin, HBD-2, and SLPI were measured by enzyme-linked immunosorbent assays. Levels of cationic polypeptides in cervicovaginal secretions were compared between women who were not using hormonal contraception and those using DMPA, oral, or implantable contraception. Among 228 women, 165 (72%) reported not using hormonal contraception at enrollment, 41 (18%) used DMPA, 16 (7%) used an oral contraceptive, and 6 (3%) used a contraceptive implant. Compared with nonusers of hormonal contraception, DMPA users had significantly higher mean levels of HNP1-3 (2.38 vs. 2.04 log₁₀ ng/mL; P = 0.024), LL-37 (0.81 vs. 0.40 log10 ng/mL; P = 0.027), and lactoferrin (3.03 vs. 2.60 log₁₀ ng/mL; P = 0.002), whereas SLPI and HBD-2 were similar. Although all analyzed cationic polypeptides have intrinsic antiviral capacity, their interaction and cumulative effect on female genital mucosa susceptibility to infections in vivo has yet to be unraveled. This study suggests a potential mechanism underlying the effect of DMPA on the innate immune defenses, providing a rationale to investigate its effect on HIV-1 acquisition risk.

    Prior studies suggest that the composition of the vaginal microbiome may positively or negatively affect susceptibility to sexually transmitted infections (STIs) and bacterial vaginosis (BV). Some female hormonal contraceptive methods also appear to positively or negatively influence STI transmission and BV. Therefore, changes in the vaginal microbiome that are associated with different contraceptive methods may explain, in part, effects on STI transmission and BV. We performed a retrospective study of 16S rRNA gene survey data of vaginal samples from a subset of participants from the Human Vaginal Microbiome Project at Virginia Commonwealth University. The subset included 682 women who reported using a single form of birth control that was condoms, combined oral contraceptives (COCs), depot medroxyprogesterone acetate (DMPA) or the levonorgestrel-releasing intrauterine system (LNG-IUS). Women using COCs [adjusted odds ratio (aOR) 0.29, 95% confidence interval (CI) 0.13-0.64] and DMPA (aOR 0.34, 95% CI 0.13-0.89), but not LNG-IUS (aOR 1.55, 95% CI 0.72-3.35), were less likely to be colonized by BV-associated bacteria relative to women who used condoms. Women using COCs (aOR 1.94, 95% CI 1.25-3.02) were more likely to be colonized by beneficial H2O2-producing Lactobacillus species compared with women using condoms, while women using DMPA (aOR 1.09, 95% CI 0.63-1.86) and LNG-IUS (aOR 0.74, 95% CI 0.48-1.15) were not. Use of COCs is significantly associated with increased vaginal colonization by healthy lactobacilli and reduced BV-associated taxa. COC use may positively influence gynecologic health through an increase in healthy lactobacilli and a decrease in BV-associated bacterial taxa. Copyright © 2016 Elsevier Inc. All rights reserved.

    Bone mineral density (BMD) loss among depot medroxyprogesterone acetate (DMPA) users is a controversial issue. Aspects under debate include whether the number of years of use has any effect on continuous BMD loss, whether this loss will stabilise over the years of use or if it will progress to low bone mass, osteoporosis and an increased fracture risk. The aim of this study was to compare the difference in osteoporosis and low bone mass between DMPA and copper intrauterine device (Cu-IUD) users. This was a cross-sectional study that evaluated BMD at the lumbar spine and femoral neck in 47 long-term DMPA users and 41 Cu-IUD users as control group. BMD was measured by dual-energy X-ray absorptiometry. The participants were 27 to 57 years of age, had used either DMPA or a Cu-IUD uninterruptedly for at least ten years, had initiated use of the method prior to 40 years of age and had follicle stimulating hormone values <40 mIU/mL. Findings showed that 68.1% and 36.6% of the DMPA and Cu-IUD users, respectively, had low bone mass and 29.8% and 2.4% of DMPA and Cu-IUD users, respectively, had osteoporosis. BMD decreased as the number of years of DMPA use increased. Long-term DMPA use was associated with low bone mass and osteoporosis in women who had used the method for 10 years or more. DMPA users with longer time of use showed a greater bone mass loss.

    Activation of the enzyme 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) in adipose tissue results in the production of excess tissue glucocorticoids and the induction of adiposity and visceral obesity in particular. Androgens may affect body fat distribution by regulating the local metabolism of cortisol. Our objective was to study 11beta-HSD1 mRNA expression in abdominal sc and omental (om) adipose tissue in children after in vitro testosterone and cortisol treatment. Paired fat biopsies (sc and om) were obtained from 19 boys (age 6-14 yr, body mass index 14.6-25.3 kg/m(2), BMI sd score SDS -1.6-3.1) undergoing open abdominal surgery. Pieces of adipose tissue were incubated with testosterone, cortisol, or both hormones for 24 h, whereupon mRNA expression of 11beta-HSD1 and hexose-6-phosphate dehydrogenase (H6PDH) were measured by real-time PCR, and 11beta-HSD1 enzyme activity was determined. Testosterone treatment up-regulated 11beta-HSD1 mRNA expression compared with control incubations in the absence of testosterone (P tissue. Testosterone and cortisol both increased 11beta-HSD1 mRNA expression in om but not sc adipose tissue in a depot-specific manner by 2.5- and 2.9-fold, respectively (P effect of the two hormones. 11beta-HSD1 enzyme activity correlated positively to mRNA expression (r = 0.610; P = 0.001). Adipose tissue mRNA expression of H6PDH was affected in a similar fashion to 11beta-HSD1 after hormonal treatment. Testosterone and cortisol stimulated 11beta-HSD1 and H6PDH mRNA expression and 11beta-HSD1 activity in om but not in sc adipose tissue. This suggests that these hormones may contribute to fat distribution and accumulation during childhood.

    Lanreotide Autogel (lanreotide Depot in the USA) has demonstrated anti-tumor activity and control of the symptoms associated with hormone hypersecretion in patients with neuroendocrine tumors. The objectives of this study were to describe the pharmacokinetics of lanreotide Autogel administered 4-weekly by deep subcutaneous injections of 60, 90, or 120 mg in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs), to quantify the magnitude of inter-patient variability (IPV), and to identify those patient characteristics that impact on pharmacokinetics. Analyses were based on pooled data from clinical trials. A total of 1541 serum concentrations from 290 patients were analyzed simultaneously by the population approach using NONMEM version 7.2. Covariates evaluated included demographics, renal and hepatic function markers, and disease-related parameters. Serum profiles were described by a one-compartment disposition model in which the absorption process was characterized by two parallel pathways following first- and zero-order kinetics. The estimated apparent volume of distribution was 18.3 L. The estimated apparent total serum clearance for a typical 74 kg patient was 513 L/day, representing a substantial difference in clearance in this population of patients with respect to healthy volunteers that could not be explained by any of the covariates tested. Body weight was the only covariate to show a statistically significant effect on the pharmacokinetic profile, but due to the overlap between the pharmacokinetic profiles of patients with lower or higher body weights the effect of body weight on clearance was not considered clinically relevant. The IPV was low for clearance (27%) and moderate to high for volume of distribution (150%) and the absorption constant (61%). Using two mechanisms of absorption, the pharmacokinetics of lanreotide Autogel were well-described in patients with GEP-NET. None of the patient characteristics tested were of clinical

    Biodegradable polymer-based injectable in situ forming depot (ISD) systems that solidify in the body to form a solid or semisolid reservoir are becoming increasingly attractive as an injectable dosage form for sustained (months to years) parenteral drug delivery. Evaluation of long-term drug release from the ISD systems during the formulation development is laborious and costly. An accelerated release method that can effectively correlate the months to years of long-term release in a short time such as days or weeks is economically needed. However, no such accelerated ISD system release method has been reported in the literature to date. The objective of the current study was to develop a short-term accelerated in vitro release method for contraceptive levonorgestrel (LNG)-containing ISD systems to screen formulations for more than 3-month contraception after a single subcutaneous injection. The LNG-containing ISD formulations were prepared by using biodegradable poly(lactide-co-glycolide) and polylactic acid polymer and solvent mixtures containing N-methyl-2-pyrrolidone and benzyl benzoate or triethyl citrate. Drug release studies were performed under real-time (long-term) conditions (PBS, pH 7.4, 37 °C) and four accelerated (short-term) conditions: (A) PBS, pH 7.4, 50 °C; (B) 25% ethanol in PBS, pH 7.4, 50 °C; (C) 25% ethanol in PBS, 2% Tween 20, pH 7.4, 50 °C; and (D) 25% ethanol in PBS, 2% Tween 20, pH 9, 50 °C. The LNG release profile, including the release mechanism under the accelerated condition D within two weeks, correlated (r2 ≥ 0.98) well with that under real-time conditions at four months.

    Individuals of black African ethnicity tend to have less visceral adipose tissue (VAT) but more subcutaneous-abdominal adipose tissue (SCAT) than white Caucasians. However, it is unclear whether such distribution of abdominal fat is beneficial for metabolic disease risk in black individuals. Here we compared the associations between these specific abdominal fat depots, insulin sensitivity and metabolic syndrome risk. A cross-sectional analysis of 76 black South African young adults (36 men; 40 women) aged 18-19 years participating in the Birth to Twenty Cohort Study had VAT and SCAT measured by MRI. The metabolic syndrome traits (blood pressure, lipid profile, fasting glucose and insulin) were measured and the values were combined into a metabolic syndrome risk score. Fasting glucose and insulin were used to derive the HOMA-index of insulin resistance (HOMA-IR). Compared to men, women had greater VAT (mean: 16.6 vs. 12.5 cm(2)) and SCAT (median 164.0 vs. 59.9 cm(2)). In men, SCAT (r = 0.50) was more strongly correlated to the metabolic syndrome score (MetS) than was VAT (r = 0.23), and was associated with both MetS (P = 0.001) and HOMA-IR (P = 0.001) after adjustment for VAT and total fat mass. In women, both abdominal fat compartments showed comparable positive correlations with MetS (r = 0.26 to 0.31), although these trends were weaker than in men. In young black South African adults, SCAT appears to be more relevant than VAT to metabolic syndrome traits.

    With the increase of our country's crude oil reserves capacity, energy consumption in oil depot production will further increase. For this kind of complex and dynamic energy consumption system composed of oil storage tank, transfer pump, heating furnace and the other energy consumption unit according to certain topological relationships, the thermodynamics exergy analysis which can be used to reflect the true value and utilization degree of enengy is applied to perform a comprehensive analysis from the view of energy quality. Firstly, the sequential modular approach was used to determine the node parameters of oil depot unit module. Then according to the technological process, the gray box exergy model of oil depot system was established. Furthermore, the positive equilibrium exergy efficiency, exergy loss coefficient and anti-balance efficiency formula were given out. The case study of exergy analysis application in a certain oil depot shows that the exergy loss coefficient of furnace is 73. 99% , which is the maximum loss in oil depot. Among its various exergy losses, exergy loss of heat exchange is up to 47%. Therefore, it is important to improve energy level match in heat exchange process of furnace for increasing the exergy efficiency of oil depot.%随着我国原油储备能力的增加,原油库的生产能耗将进一步增大.对于油库这种由储油罐、输油泵、加热炉等用能单元按照一定拓扑关系连接组成的总能系统,热力学(火用)分析方法可从能质角度对其进行全面分析,反映能的真正价值和利用程度.首先采用序贯模块法确定油库系统各单元模块的节点参数,然后根据工艺流程的特点,建立了系统(火用)分析的灰箱模型,给出了正平衡(火用)效率、(火用)损系数及反平衡(火用)效率的计算式.对某油库进行(火用)分析的应用实例研究,结果表明加热炉的(炯)损系数为73.99%,是油库(火用)损最大的设备;在其各项(火用)

    Our aim was to assess the attainment of primary (low density lipoprotein cholesterol; LDL-C) and secondary (non-high density lipoprotein cholesterol; non-HDL-C) lipid therapeutic goals in relation to obesity, clinical measures of adiposity and ultrasound indexes of fat depots, including the novel index of periarterial adipose tissue (PAT): carotid artery extra media thickness (EMT). High and very high cardiovascular (CV) risk patients (n = 420; F/M: 34/66%; age: 61.2 ± 7 years) with prior statin treatment (≥ 18 months) were enrolled into this cross-sectional study. All patients had a detailed assessment with several anthropometric measures and ultrasound indexes of fat depots indexed to BMI: abdominal (Intra-abdominal Fat Thickness; IAT and Pre-peritoneal Fat Thickness; PreFT), paracardial (Epicardial Fat Thickness; EFT and Pericardial Fat Thickness; PFT) and the new index corresponding to PAT (carotid EMT). Lipid goals attainment in the study group was as follows: 34% (LDL-C goal), 39% (non-HDL-C goal) and 35% (both LDL and non-HDL-C goals). Among ultrasound indexes, patients with both lipid goals attainment revealed significantly lower carotid EMT/BMI (LDL-C goal: 25.2 ± 4.2 vs 27.5 ± 4.1, p obesity and most clinical measures of adiposity, carotid EMT and abdominal IAT, but not other ultrasound indexes of fat depots revealed associations independent from BMI with lipid goal attainment and may help identify patients requiring more aggressive lipid management.

    Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis has the remarkable ability to persist as non-replicating forms in the host. These persisters are tolerant to drugs targeting actively replicating bacilli and hence are responsible for the need of an extended duration of anti-tubercular therapy. The anatomical locations and cell types housing Mtb persisters are being investigated in the recent times. Adipose tissue and the adipocytes are proposed niches of Mtb persisters. In the present study, we carried out experiments in the immunocompetent Swiss mice to see the dissemination of Mtb from lungs to adipose tissue and vice versa. Mice infected intra-nasally with ∼ 10(6), 10(4) or 10(2) bacilli harboured Mtb in various adipose depots distal to the lungs such as the visceral, subcutaneous and peri-renal depots. The dissemination was minimal at two weeks post-infection, as evident from culture negative adipose tissue samples. But at seven weeks post-infection, viable Mtb could be detected in 78%, 66% and 66% of the samples from high, moderate and low dose-infection groups respectively. In a separate experiment, Mtb-infected pre-adipocytes were implanted subcutaneously to un-infected mice. At five weeks post-implantation, the intact implants had a mean 7 ± 0.53 log10 CFUs/100 mg tissue, while the lungs had a mean 3.25 ± 0.32 log10 CFUs/100 mg tissue. In conclusion, the study shows that Mtb can disseminate from lungs to distant adipose depots and vice versa.

    High-security hospital patients are often complex in presentation and are characterized by treatment resistance, medication nonadherence and history of violence. Paliperidone is licensed both as an oral and depot antipsychotic medication in the treatment of schizophrenia. Clinical trials have shown that paliperidone depot is well tolerated with similar efficacy to risperidone depot but with additional practical advantages. Whilst data exist for the effectiveness of paliperidone palmitate (PP), there are no studies involving patients in forensic settings or those with comorbid personality disorder. Our aim was to evaluate the effectiveness of PP on violence, aggression and personality disorder symptoms. This project was a retrospective service evaluation involving 11 patients, carried out in a high-security hospital. A combination of patient records and interviews with the treating consultant psychiatrist were used to ascertain a Clinical Global Impression (CGI) score, the effect of PP on specific personality disorder symptom domains (cognitive-perceptual, impulsive-behavioural dyscontrol and affective dysregulation) and incidents of violence and aggression. Engagement with occupational and psychological therapies was also evaluated. Metabolic parameters were reviewed. A total of 6 out of 11 patients continued on PP, most of whom had schizophrenia and dissocial personality disorder with histories of violence. All showed improvement in the CGI score with associated benefits in the three personality symptom domains. Overall, two patients demonstrated a reduction in the risk of violence. There was improvement in engagement with occupational therapy and psychological work. No significant effects on metabolic parameters were noted although hyperprolactinaemia, albeit asymptomatic, was consistently recorded. This pragmatic service evaluation of a small but complex patient group demonstrated, for the first time, that PP was effective in reducing violence as well as

    A randomized controlled trial 'Money for Medication'(M4M) was conducted in which patients were offered financial incentives for taking antipsychotic depot medication. This study assessed the attitudes and ethical considerations of patients and clinicians who participated in this trial. Three mental healthcare institutions in secondary psychiatric care in the Netherlands participated in this study. Patients (n = 169), 18-65 years, diagnosed with schizophrenia, schizoaffective disorder or another psychotic disorder who had been prescribed antipsychotic depot medication, were randomly assigned to receive 12 months of either treatment as usual plus a financial reward for each depot of medication received (intervention group) or treatment as usual alone (control group). Structured questionnaires were administered after the 12-month intervention period. Data were available for 133 patients (69 control and 64 intervention) and for 97 clinicians. Patients (88%) and clinicians (81%) indicated that financial incentives were a good approach to improve medication adherence. Ethical concerns were categorized according to the four-principles approach (autonomy, beneficence, non-maleficence, and justice). Patients and clinicians alike mentioned various advantages of M4M in clinical practice, such as increased medication adherence and improved illness insight; but also disadvantages such as reduced intrinsic motivation, loss of autonomy and feelings of dependence. Overall, patients evaluated financial incentives as an effective method of improving medication adherence and were willing to accept this reward during clinical treatment. Clinicians were also positive about the use of this intervention in daily practice. Ethical concerns are discussed in terms of patient autonomy, beneficence, non-maleficence and justice. We conclude that this intervention is ethically acceptable under certain conditions, and that further research is necessary to clarify issues of benefit

    Recent evidence indicates that epicardial adipose tissue (EAT) expresses uncoupling protein-1 (UCP1), a marker of brown adipocytes. However, the putative effects of the presence of brown adipocytes in EAT remain unknown. The mRNA expression of genes related to brown adipocyte-mediated thermogenesis was measured in the fat samples collected from the epicardial-, mediastinal- and subcutaneous-depots of patients undergoing coronary artery bypass grafting. Both univariate and multivariate analyses were then utilized to determine any association between gene expression and the anthropometrics and fasting blood chemistries of these patients. EAT exhibited significantly higher expression of UCP1 and cytochrome c oxidase subunit-IV (COX-IV) compared to mediastinal- and subcutaneous-fat depots (P ≤ 0.05). EAT expression of UCP1 (r=0.50), COX-IV (r=0.37) and lipoprotein lipase (LPL) (r=0.58) positively associated with circulating levels of HDL-cholesterol (P ≤ 0.05). In addition, EAT expression of LPL, acyl coA dehydrogenase-short, -medium and -long chain genes associated negatively with circulating TG levels (P ≤ 0.05). Abundance of UCP-1 in the EAT relative to other fat depots confirms the presence of brown adipocytes in human EAT. Furthermore, the correlations among the EAT expression of thermogenesis-related genes with the circulating HDL and TG levels indicate that presence of active brown adipocytes shares a functional association with the circulating plasma lipids in humans.

    A factorial experiment was performed with 117 barrows belonging to the Iberian (IB) and crossbred F Large White × Landrace (F) genetic groups, either intensively finished (IN) or finished outdoors on pasture in an oak and cork tree forest (EX). Information was collected on carcass weight, yield, and dimensions; weight of organs, carcass cuts, and abdominal fat depots; backfat depth; measurements of the longissimus thoracis (LT); and yield of different leg tissues. For the 41 slaughter and carcass traits analyzed, the interaction between genetic group and finishing system was significant ( 0.05), indicating that it is feasible to reduce subcutaneous and abdominal fat without compromising IMF and meat quality.

    Objective. To ascertain the relationship between the Ala54Thr variation of FABP2 gene and general as well as regional adipose tissue depots.Subjects. 165 subjects, in which 86 were subjects with normal glucose tolerance (NGT) [age 54.45±9.80, male/female 1.05,body mass index (BMI)26.48±4.01] and 79 were subjects with non-insulin-dependent diabetes mellitus (NIDDM)(age 55.86±10.00,male/female 1.08,BMI 26.75±3.30).Design and measurements. An association study of FABP2-Ala54Thr variation detected by PCR/HhaI digestion with general and regional adipose tissue depots determined by BMI and magnetic resonance imaging [abdominal subcutaneous and visceral adipose tissue area (SA and VA) and femoral subcutaneous adipose tissue area (FA)].Results. The geneotype and allele frequencies of FABP2-Ala54Thr variation in Chinese were quite close to the frequencies in American Caucasians and Pima Indians reported in the literature. Significant difference in genotype frequency distribution was observed between FA subgroups comparisons (FA≥75cm2 versus FA<75cm2)in NIDDM subjects (X2=11.460,P=0.003),with significantly increased in Thr54-carrier[Thr54(+)]genotype frequency and Thr54 allele frequency in NIDDM subject with FA<75cm2(odd ratio for genotype was 4.62,X2=10.112,P=0.001;and for allele=2.36,X2=5.379,P=0.020).The FA in NIDDM-Thr54(+)subgroup was significantly lower than that in subjects with NIDDM-Thr54(-)sugroup(61.19±21.51cm2 versus 75.36±31.70cm2,P=0.021). Stepwise regression analysis revealed that FABP2-Thr54 genotype variation was an independent factor contributing to the variation of FA in NIDDM(P=0.003).Conclusion. FABP2 is associated with regional adipose tissue depot.The decreased femoral subcutaneous adipose tissue depot in NIDDM subjects is related to FABP2-Thr54 variant.

The aim of the presented studies was to establish whether lanreotide depot, administered to patients with acromegaly at an extended dosing interval of 6 or 8 weeks, is effective in maintaining appropriate serum growth hormone (GH and insulin-like growth factor-1 (IGF-1 levels, with acceptable tolerability.Methods: Two studies were conducted. Study B1 compared lanreotide depot 120 mg (every 4, 6, or 8 weeks with lanreotide microparticle formulation 30 mg (every 7, 10, or 14 days in 98 patients who had a GH level of ≤2.5 ng/mL and normalized IGF-1. Study B2 evaluated lanreotide depot 120 mg administered to 64 patients every 8 weeks, after which the dosing interval was adjusted based on GH levels.Results: Mean lanreotide trough serum concentrations at steady state for all dosing intervals were >1.13 ng/mL, shown to achieve a GH level of ≤2.5 ng/mL. In Study B1, following treatment with lanreotide depot given every 6 or 8 weeks, 87.5% and 93.9% of patients, respectively, had normalized GH, whereas 83.3% and 88.5% of patients, respectively, had both normalized GH and IGF-1. In Study B2, 88.9% had normalized GH and 42.9% of patients had normalized GH and IGF-1 following lanreotide depot every 8 weeks. Gastrointestinal disorders, generally mild/moderate in severity, were the most common adverse events.Conclusion: In the studies presented, lanreotide depot 120 mg every 4, 6, or 8 weeks provided effective hormonal control with acceptable safety. An extended dosing interval is a feasible approach for patients adequately controlled with lanreotide depot 60 or 90 mg every 4 weeks

    Background: The role of persistent organic pollutants (POPs) with endocrine disrupting activity in the aetiology of obesity and other metabolic dysfunctions has been recently highlighted. Adipose tissue (AT) is a common site of POPs accumulation where they can induce adverse effects on human health. Objectives: To evaluate the presence of POPs in human visceral (vAT) and subcutaneous (scAT) adipose tissue in a sample of Portuguese obese patients that underwent bariatric surgery, and assess their putative association with metabolic disruption preoperatively, as well as with subsequent body mass index (BMI) reduction. Methods: AT samples (n=189) from obese patients (BMI ≥35) were collected and the levels of 13 POPs were determined by gas chromatography with electron-capture detection (GC-ECD). Anthropometric and biochemical data were collected at the time of surgery. BMI variation was evaluated after 12 months and adipocyte size was measured in AT samples. Results: Our data confirm that POPs are pervasive in this obese population (96.3% of detection on both tissues), their abundance increasing with age (R{sub S}=0.310, p<0.01) and duration of obesity (R{sub S}=0.170, p<0.05). We observed a difference in AT depot POPs storage capability, with higher levels of ΣPOPs in vAT (213.9±204.2 compared to 155.1±147.4 ng/g of fat, p<0.001), extremely relevant when evaluating their metabolic impact. Furthermore, there was a positive correlation between POP levels and the presence of metabolic syndrome components, namely dysglycaemia and hypertension, and more importantly with cardiovascular risk (R{sub S}=0.277, p<0.01), with relevance for vAT (R{sub S}=0.315, p<0.01). Finally, we observed an interesting relation of higher POP levels with lower weight loss in older patients. Conclusion: Our sample of obese subjects allowed us to highlight the importance of POPs stored in AT on the development of metabolic dysfunction in a context of obesity, shifting the focus to their

    To describe medroxyprogesterone acetate (MPA) levels among Kenyan depot medroxyprogesterone acetate (DMPA) users in the FEM-PrEP HIV prevention trial, and to compare MPA levels between ARV for HIV prevention (treatment) and placebo groups. We measured MPA in previously collected plasma samples from 63 Kenyan trial participants who used DMPA for one or two complete intervals. We separately assessed MPA levels among the nine DMPA users who became pregnant at this site. Mean MPA levels at the end of each 12week injection interval were 0.37ng/ml (95% CI: 0.25, 1.99) and 0.28ng/ml (95% CI: 0.19, 1.22) among participants assigned TDF/FTC and 0.49 (95% CI: 0.40, 1.27) and 0.39 (95% CI: 0.31, 1.17) among those assigned placebo. The difference between groups was not statistically significant overall, or in an analysis which adjusted for the observed low adherence to TDF/FTC. Unanticipated findings of this analysis were low 12-week MPA levels among DMPA users in both study arms. Of 61 women who contributed data for the first DMPA injection interval, 26.2% had MPA levels<0.1ng/ml and 9.8% had levels below the detection level (0.02ng/ml) at 12weeks post-injection. Levels were similar at the end of the second injection interval. Five of nine women who became pregnant had levels below 0.15ng/mL at the time of their last negative pregnancy test. Use of TDF/FTC did not appear to affect serum MPA levels, however we found lower than expected MPA concentrations at the end of the dosing interval among DMPA users in the FEM-PrEP trial, the cause of which are unknown. This study presents some of the few available data on MPA levels among DMPA users in Africa. The low levels among users described here, together with a number of pregnancies among DMPA users, are potentially concerning and require further investigation. Copyright © 2016 The Authors.

    Women who have abortions are at high risk of contraception discontinuation and subsequent unintended pregnancy. The objective of this analysis was to identify factors associated with choice of highly effective, long-acting, progestin-only contraceptive methods after abortion. Women presenting for surgical abortion who selected the levonorgestrel intrauterine device (IUD), the progestin implant or the progestin injection (depot medroxyprogesterone acetate or DMPA) as their postabortion contraceptives were recruited to participate in a 1-year prospective cohort study. We used multivariable multinomial logistic regression to identify factors associated with choosing long-acting reversible contraceptives (IUD or implant) compared to DMPA. A total of 260 women, aged 18-45 years, enrolled in the study, 100 of whom chose the IUD, 63 the implant and 97 the DMPA. The women were 24.9 years old on average; 36% were black, and 29% were Latina. Fifty-nine percent had had a previous abortion, 66% a prior birth, and 55% were undergoing a second-trimester abortion. In multivariable analyses, compared with DMPA users, women who chose the IUD or the implant were less likely to be currently experiencing intimate partner violence (IPV); reported higher stress levels; weighed more; and were more likely to have finished high school, to have used the pill before and to report that counselors or doctors were helpful in making the decision (all significant at p<.05, see text for relative risk ratios and confidence intervals.) In addition, women who chose the IUD were less likely to be black (p<.01), and women who chose the implant were more likely to report that they would be unhappy to become pregnant within 6 months (p<.05) than DMPA users. A variety of factors including race/ethnicity, past contraceptive use, feelings towards pregnancy, stress and weight were different between LARC and DMPA users. Notably, current IPV was associated with choice of DMPA over the IUD or implant, implying

    Evidence on contraceptive self-injection from the United States and similar settings is promising, and the practice may increase access. There are no published studies on the feasibility of contraceptive self-injection in sub-Saharan Africa to date. The purpose of this study was to assess feasibility of subcutaneous depot medroxyprogesterone acetate self-injection in Uganda, with specific objectives to (a) measure the proportion of participants who self-injected competently, (b) measure the proportion who self-injected on time 3 months after training (defined conservatively as within 7 days of their reinjection date) and (c) assess acceptability. In this prospective cohort study, 380 18-45-year-old participants completed self-injection training by licensed study nurses, guided by a client instruction booklet, and practiced injection on prosthetics until achieving competence. Nurses supervised participants' self-injection and evaluated injection technique using an observation checklist. Those judged competent were given a Sayana® Press unit, instruction booklet and reinjection calendar for self-injection at home 3 months later. Participants completed an interview before and after self-injection. Nurses visited participants at home following reinjection dates; during the follow-up visit, participants demonstrated self-injection on a prosthetic, injection technique was reevaluated, and a postreinjection interview was completed. Of 368 participants followed up 3 months posttraining, 88% [95% confidence interval (CI)=84-91] demonstrated injection competence, and 95% (95% CI=92-97) reinjected on time, while 87% (95% CI=84-90) were both on time and competent. Nearly all (98%) expressed a desire to continue. Self-injection is feasible and highly acceptable among most study participants in Uganda. The first research results on contraceptive self-injection in sub-Saharan Africa indicate initial feasibility and acceptability of the practice 3 months after women received one

    There has been concerning about women receiving depot medroxyprogesterone acetate (DMPA) contraception because of the prolonged hypoestrogenemic state regarding the potential negative effects on bone health. This study showed that DMPA exposure is associated with increased fracture risk and that fracture risk increases with longer DMPA exposure. DMPA has been associated with impaired bone mineral acquisition during adolescence and accelerated bone loss in later life. We performed this large population-based study to assess the association between use of DMPA or combined oral contraceptives and the incident risk of fracture. We identified 4189 women between 20 and 44 years of age with a first-time fracture diagnosis, matched them with 4189 random controls using the Disease Analyzer database and investigated the relation with DMPA exposure. Overall, 11 % of the fracture cases and 7.7 % of the controls had DMPA use recorded. The adjusted OR for developing a fracture in patients with current use of DMPA compared to non-users was 0.97 (95 % CI 0.51-1.86), 2.41 (95 % CI 1.42-4.08), and 1.46 (95 % CI 0.96-2.23) for 1-2, 3-9, and ≥10 prescriptions, respectively. The adjusted OR for developing a fracture in patients with past use of DMPA compared to non-users was 0.96 (95 % CI 0.73-1.26), 1.14 (95 % CI 0.86-1.51), and 1.55 (95 % CI 1.07-2.27) for 1-2, 3-9, and ≥10 prescriptions, respectively. The highest fracture risk was identified in young patients less than 30 years with longer DMPA exposure (≥10 prescriptions; OR 3.04, 95 % CI 1.36-6.81), as well as in patients in the late reproductive years with past use of DMPA (OR 1.72, 95 % CI 1.13-2.63). Our results indicate that DMPA exposure is associated with increased fracture risk and may have negative effects on bone metabolism, resulting in impaired bone mineral acquisition during adolescence and accelerated bone loss in adult life.

    Background Fat accumulation in android compartments may confer increased metabolic risk. The incremental utility of measuring regional fat deposition in association with metabolic syndrome (MS) has not been well described particularly in an elderly population. Methods and Findings As part of the Korean Longitudinal Study on Health and Aging, which is a community-based cohort study of people aged more than 65 years, subjects (287 male, 75.9±8.6 years and 278 female, 76.0±8.8 years) with regional body composition data using Dual energy X-ray absorptiometry for android/gynoid area, computed tomography for visceral/subcutaneous adipose tissue (VAT/SAT), and cardiometabolic markers including adiponectin and high-sensitivity CRP were enrolled. We investigated the relationship between regional body composition and MS in multivariate regression models. Mean VAT and SAT area was 131.4±65.5 cm2 and 126.9±55.2 cm2 in men (P = 0.045) and 120.0±46.7 cm2 and 211.8±65.9 cm2 in women (Pandroid and gynoid fat amount was 1.8±0.8 kg and 2.5±0.8 kg in men and 2.0±0.6 kg and 3.3±0.8 kg in women, respectively (both Pandroid fat amount was strongly correlated with most metabolic risk factors compared to SAT or gynoid fat. Furthermore, android fat amount was significantly associated with clustering of MS components after adjustment for multiple parameters including age, gender, adiponectin, hsCRP, a surrogate marker of insulin resistance, whole body fat mass and VAT area. Conclusions Our findings are consistent with the hypothesized role of android fat as a pathogenic fat depot in the MS. Measurement of android fat may provide a more complete understanding of metabolic risk associated with variations in fat distribution. PMID:22096613

    2015-06-01

    The ethical issues experienced by mental health nurses in administering antipsychotic depot and long-acting intramuscular injections (LAI) were explored in the present study. Mental health nurses face ethically-difficult situations when administering these medications. A phenomenological research method guided by Max van Manen's human science approach describes and interprets the ethical issues involved in performing the procedure. Purposive and snowball sampling was used to select eight participants from two mental health hospitals. Semistructured interviews were carried out to collect data. A thematic analysis was conducted on the data. The four main themes that emerged from the analyses were: (i) lack of alternatives; (ii) safety; (iii) feeling uncomfortable; and (iv) difficulty maintaining the therapeutic relationship. The findings suggest that mental health nurses face ethical challenges in administering LAI. The findings raise much needed awareness of the need for mental health nurses and nurse educators to consider the ethical issues experienced while performing the procedure. There is a need for nurse education providers and organizations to provide opportunities for mental health nurses to address their 'lived experiences'. Educational courses are needed to equip mental health nurses with the technical and critical thinking skills to administer safe and effective antipsychotic depot and LAI.

    Neuroscience today deals with a "data deluge" derived from the availability of high-throughput sensors of brain structure and brain activity, and increased computational resources for detailed simulations with complex output. We report here (1) a novel approach to data sharing between collaborating scientists that brings together file system tools and cloud technologies, (2) a service implementing this approach, called NeuronDepot, and (3) an example application of the service to a complex use case in the neurosciences. The main drivers for our approach are to facilitate collaborations with a transparent, automated data flow that shields scientists from having to learn new tools or data structuring paradigms. Using NeuronDepot is simple: one-time data assignment from the originator and cloud based syncing-thus making experimental and modeling data available across the collaboration with minimum overhead. Since data sharing is cloud based, our approach opens up the possibility of using new software developments and hardware scalabitliy which are associated with elastic cloud computing. We provide an implementation that relies on existing synchronization services and is usable from all devices via a reactive web interface. We are motivating our solution by solving the practical problems of the GinJang project, a collaboration of three universities across eight time zones with a complex workflow encompassing data from electrophysiological recordings, imaging, morphological reconstructions, and simulations.

    Dysregulation of immune cells and/or altered inflammatory signaling have been implicated with reproductive dysfunction. Physiological changes leading to perturbations in the profile of immune cells and/or pro-inflammatory cytokines in or around female reproductive tissue could potentially have profound effects on ovarian function. Obesity is associated with chronic low-grade inflammation due, in part, to increased immune cell infiltration and inflammation in visceral adipose depots. This study investigated the impact of diet-induced obesity on immune cell infiltration and inflammation in peri-ovarian adipose tissue and mRNA expression of key inflammatory markers and microRNAs (miRs) in ovarian tissue. Six-week-old female C57Bl/6J mice were fed a standard chow or high-fat diet (HFD; 60% kcal fat) for approximately 7 months, at which time peri-ovarian adipose tissue and ovarian tissues were collected. Histological analysis of peri-ovarian adipose tissue from obese mice revealed increased (P adipocyte size and the presence of crown-like structures, the morphological presentation of infiltrating immune cells in adipose tissue, along with increases (P tissue (P adipose depot, potentially negatively affecting ovarian function. © 2013 Wiley Periodicals, Inc.

    Cotton-top tamarins (Saguinus oedipus) are a critically endangered species that have been bred successfully in captivity for many years. For two decades, the Cotton-top Tamarin SSP(©) has been challenged with a high rate of reproduction combined with a history of contraceptive failures and nonrecommended births using the current Depo Provera(®) (medroxyprogesterone acetate) injection followed by MGA (melengestrol acetate) implant contraception combination. To address these issues we have developed and tested the use of levonorgestrel (LNG) as an effective contraception option for cotton-top tamarins. LNG was delivered in an injectable, gel matrix consisting of polylactic-co-glycolic acid, triethyl citrate and N-methylpyrrolidone. This gel matrix forms a biodegradable depot at the subcutaneous injection site providing slow release of the active ingredient. Gel matrix composition and LNG concentration were adjusted in four gel formulations to maximize the duration of contraceptive efficacy while minimizing immediate post-injection increases in fecal LNG concentration. LNG treatment (68.44 ± 8.61 mg/kg) successfully eliminated ovarian cycles (fecal pregnanediol-3-glucuronide (PdG) and estrone conjugates (E(1) C)) for 198.8 ± 70.3 days (formulation four; range 19-50 weeks). It was demonstrated that subcutaneous LNG depot injection was an effective, reversible contraceptive option for the management of cotton-top tamarins in captivity.

    Full Text Available Indirect evidence suggests that adipose tissue-derived stromal cells (ASCs possess different physiological and biological variations related to the anatomical localization of the adipose depots. Accordingly, to investigate the influence of the tissue origin on the intrinsic properties of ASCs and to assess their response to specific stimuli, we compared the biological, functional and ultrastructural properties of two ASC pools derived from mediastinal and subcutaneous depots (thoracic compartment by means of supplements such as platelet lysate (PL and FBS. Subcutaneous ASCs exhibited higher proliferative and clonogenic abilities than mediastinal counterpart, as well as increased secreted levels of IL-6 combined with lower amount of VEGF-C. In contrast, mediastinal ASCs displayed enhanced pro-angiogenic and adipogenic differentiation properties, increased cell diameter and early autophagic processes, highlighted by electron microscopy. Our results further support the hypothesis that the origin of adipose tissue significantly defines the biological properties of ASCs, and that a homogeneric function for all ASCs cannot be assumed.

    Full Text Available In 1994 the Koninklijke Bibliotheek (KB decided to include electronic publications in its deposit collection. This was considered as a logical extension of the deposit for printed publications already in place. In December 2002, after a few years of experimenting, the current e-Depot was delivered, with the IBM Digital Information and Archiving System (DIAS as its technical 'heart'. The e-Depot is now fully operational and imbedded in the KB organisation. The emergence of the electronic journal creates new challenges to the traditional deposit model. Because of the involvement of international publishers of Dutch origin, the e-Depot has had an international dimension right from the start. In 2002 the KB signed an historic electronic archiving agreement with Elsevier Science, which covered the entire set of Elsevier journals. This arrangement turned the KB into the first official digital archive in the world for journals published by international scientific publishers. A year later the KB concluded a similar agreement with Kluwer Academic Publishers. Other publishers followed, also from outside the Netherlands: Biomed Central, Blackwell, Oxford University Press, Taylor and Francis, Sage, Springer and Brill Academic Publishers. On the basis of these agreements the e-Depot will eventually hold 9 million articles. The annual increase in the number of articles from these publishers will be around 400,000. Publishers are required to deposit their publications free of charge. Access is restricted: only on-site, for any registered user of the KB. Remote access is only offered with permission of the publisher. On-site retrieval, access, printing, downloading is for private use only, systematic reproduction is not allowed. Documents are available for interlibrary document supply within the Netherlands. The archive serves as a guarantee to all licensees worldwide. In case of calamities or in case the publisher does not meet his obligations, the KB

    Menzerite-(Y), a new mineral species, forms reddish brown cores, n = 1.844 (20), up to 70 {micro}m across, rimmed successively by euhedral almandine containing up to 2.7 wt% Y{sub 2}O{sub 3} and by K-feldspar in a felsic granulite on Bonnet Island in the interior Parry Sound domain, Grenville Orogenic Province, Canada. It is named after Georg Menzer (1897-1989), the German crystallographer who solved the crystal structure of garnet. Single-crystal X-ray-diffraction results yielded space group Ia3d, a = 11.9947(6) {angstrom}. An electron-microprobe analysis of the grain richest in Y (16.93 wt% Y{sub 2}O{sub 3}) gave the following formula, normalized to eight cations and 12 oxygen atoms: {l_brace}Y{sub 0.83}Gd{sub 0.01}Dy{sub 0.05}Ho{sub 0.02}Er{sub 0.07}Tm{sub 0.01}Yb{sub 0.06}Lu{sub 0.02}Ca{sub 1.37}Fe{sub 0.49}{sup 2+}Mn{sub 0.07}{r_brace} [Mg{sub 0.55}Fe{sub 0.42}{sup 2+}Fe{sub 0.58}{sup 3+}Al{sub 0.35} V{sub 0.01}Sc{sub 0.01}Ti{sub 0.08}](Si{sub 2.82}Al{sub 0.18})O{sub 12}, or {l_brace}(Y,REE)(Ca,Fe{sup 2+}){sub 2}{r_brace}[(Mg,Fe{sup 2+})(Fe{sup 3+},Al)](Si{sub 3})O{sub 12}. Synchrotron micro-XANES data gave Fe{sup 3+}/{Sigma}Fe = 0.56(10) versus 0.39(2) calculated from stoichiometry. The scattering power refined at the octahedral Y site, 17.68 epfu, indicates that a relatively light element contributes to its occupancy. Magnesium, as determined by electron-microprobe analyses, would be a proper candidate. In addition, considering the complex occupancy of this site, the average Y-O bond length of 2.0244(16) {angstrom} is in accord with a partial occupancy by Mg. The dominance of divalent cations with Mg > Fe{sup 2+} and the absence of Si at the octahedral Y site (in square brackets) are the primary criteria for distinguishing menzerite-(Y) from other silicate garnet species; the menzerite-(Y) end-member is {l_brace}Y{sub 2}Ca{r_brace}[Mg{sub 2}](Si{sub 3})O{sub 12}. The contacts of menzerite-(Y) with almandine are generally sharp and, in places, cuspate. It is

In this paper, by means of investigation on the reserves of freight trains and depot repair bays, and in combination with the prediction on the reserves of freight trains, the conflicts between the freight train's growth and the freight train maintenance capacity in depot was analyzed for the whole railways and for the Western Inner Mongolia-to-Central China Railway which would be used for coal transportation. Furthermore, this paper proposed the measures to improve the freight train maintenance capacity in depot, such as building new ( or expanding ) freight train depots, enhancing repairing technical equipment, optimizing organization management, reforming repair schedule and repair regulations, and so on. Finally, this paper proposed a scheme of facility layout in the freight train depots ( or repairing workshops) for Western Inner Mongolia-to-Central China Railway, and analyzed the measures for improving the

    To evaluate the efficacy and safety of lanreotide depot/autogel 120 mg for the control of carcinoid syndrome (CS) symptoms in patients with neuroendocrine tumors (NETs). This was a 16-week, randomized, double-blind, phase 3 trial (Clinicaltrials.gov: NCT00774930). Patients with/without prior somatostatin analog (SSA) use were randomized to lanreotide depot/autogel 120 mg or placebo every 4 weeks, with access to short-acting octreotide as rescue medication. The primary endpoint was the percentage of days in which short-acting octreotide was used, which was assessed from daily diaries using an analysis of covariance including the stratification variables baseline short-acting octreotide use and frequency of diarrhea/flushing. The proportions of patients experiencing treatment success was a supportive analysis. Adverse events were recorded at all visits. A total of 115 patients were enrolled (lanreotide, n = 59; placebo, n = 56). The adjusted mean (95% confidence interval [CI]) percentage of days with rescue octreotide use (primary endpoint) was significantly lower in the lanreotide (33.7%; 95% CI, 25.0%-42.4%) versus the placebo group (48.5%; 95% CI, 39.6%-57.4%), representing an absolute difference of -14.8% (95% CI, -26.8% to -2.8%; P = .017). The odds ratio of full/partial treatment success (≤3 days short-acting octreotide use weeks 12 to 15) was significantly greater with lanreotide than placebo (2.4; 95% CI, 1.1-5.3; P = .036). No new safety concerns were identified, and lanreotide was well tolerated. Lanreotide depot/autogel is effective for the control of CS symptoms in patients (SSA-naïve or experienced) with NETs.

    Depot medroxyprogesterone acetate (DMPA), a progestogen-only contraceptive injectable, has traditionally been formulated as a crystalline suspension delivered intramuscularly (IM) at a dose of 150mg/1.0mL. A new, lower dose formulation of DMPA (104mg/0.65mL) has been developed for subcutaneous administration (SC). Given its increasing global availability and public health relevance, DMPA-SC was prioritized for inclusion as a new method referenced in the World Health Organization (WHO) Medical Eligibility Criteria for Contraceptive Use (MEC), 5th Edition. This systematic review evaluated the published peer-reviewed literature regarding the safety of DMPA-SC among women with various characteristics or medical conditions. Results of this review informed the decision-making of a WHO Guideline Development Group in order to include recommendations on contraceptive eligibility within the revised MEC. We searched PubMed and Cochrane Library databases to identify all relevant evidence published in peer-reviewed journals regarding the safety of DMPA-SC when used by women of reproductive age, particularly those with select characteristics or conditions specified in the MEC, from inception through June 2015. The quality of each individual study was assessed using the system for grading evidence developed by the United States Preventive Services Task Force. Fourteen studies met criteria for inclusion. Ten reported results relevant to DMPA users of varying age or with obesity, endometriosis or HIV; four compared the safety of DMPA-SC and DMPA-IM when used by general populations of healthy women. A randomized trial evaluating changes in bone mineral density among adult DMPA-SC and DMPA-IM users demonstrated no differences at 2years of follow-up. Limited evidence reported no consistent differences in weight change or bleeding patterns according to age; however, adolescents (<18years) were not included in any studies. Similar contraceptive efficacy, weight change, bleeding patterns

    Peroxisome proliferator-activated receptor γ (PPARγ) is a master regulator of adipocyte differentiation and function. We and others have previously mapped PPARγ binding at a genome-wide level in murine and human adipocyte cell lines and in primary human adipocytes. However, little is known about...... how binding patterns of PPARγ differ between brown and white adipocytes and among different types of white adipocytes. Here we have employed chromatin immunoprecipitation combined with deep sequencing to map and compare PPARγ binding in in vitro differentiated primary mouse adipocytes isolated from...... epididymal, inguinal, and brown adipose tissues. While these PPARγ binding profiles are overall similar, there are clear depot-selective binding sites. Most PPARγ binding sites previously mapped in 3T3-L1 adipocytes can also be detected in primary adipocytes, but there are a large number of PPARγ binding...

GnRH analog therapy can reduce testosterone to “castrate” levels, historically defined as <50 ng/dL. With the advent of newer assays, a lower threshold of <20 ng/dL has recently been proposed. We report the results of a retrospective analysis of two Phase III trials of 4- and 6-month depot microsphere formulations of leuprolide acetate (LA, a GnRH agonist that has previously demonstrated efficacy in testosterone suppression to <50 ng/dL in patients on ADT. This analysis investigates the ability of these LA formulations to suppress to ≤20 ng/dL levels.Methods: In two of five AbbVie/Abbott clinical trials of microsphere formulations of LA for ADT, analytic technology permitting testosterone detection as low as 3 ng/dL was used and thus was selected for this analysis. Both trials were open-label, fixed-dose studies in prostate cancer patients, naïve to ADT. Patients received either 30 mg (4-month formulation; n=49 or 45 mg (6-month formulation; n=151 depot injections of LA microspheres. Treatment duration was up to 32 weeks for the 4-month formulation and 48 weeks for the 6-month formulation. The proportion of patients achieving the 20 ng/dL threshold was determined every 4 weeks.Results: Pooled analysis showed that 152 of 193 (79% of patients achieved serum testosterone levels of ≤20 ng/dL at 4 weeks, and

    The effects of particle size of microspheres on the drug release from a microsphere/sucrose acetate isobutyrate (SAIB) hybrid depot (m-SAIB) was investigated to develop a long-term sustained release drug delivery system with low burst release both in vitro and in vivo. A model drug, risperidone, was first encapsulated into PLGA microspheres with different particle sizes using conventional emulsification and membrane emulsification methods. The m-SAIB was prepared by dispersing the risperidone-microspheres in the SAIB depot. The drug release from m-SAIB was double controlled by the drug diffusion from the microspheres into SAIB matrix and the drug diffusion from the SAIB matrix into the medium. Large microspheres (18.95 ± 18.88 µm) prepared by the conventional homogenization method exhibited porous interior structure, which contributed to the increased drug diffusion rate from microspheres into SAIB matrix. Consequently, m-SAIB containing such microspheres showed rapid initial drug release (Cmax = 110.1 ±54.2 ng/ml) and subsequent slow drug release (Cs(4-54d)= 2.7 ± 0.8 ng/ml) in vivo. Small microspheres (5.91 ± 2.24 µm) showed dense interior structure with a decreased drug diffusion rate from microspheres into SAIB matrix. The initial drug release from the corresponding m-SAIB was significantly decreased (Cmax = 40.9 ± 13.7 ng/ml), whereas the drug release rate from 4 to 54 d was increased (Cs(4-54d)=4.1 ± 1.0 ng/ml). By further decreasing the size of microspheres to 3.38 ± 0.70 µm, the drug diffusion surface area was increased, which subsequently increased the drug release from the m-SAIB. These results demonstrate that drug release from the m-SAIB can be tailored by varying the size of microspheres to reduce the in vivo burst release of SAIB system alone.

    Full Text Available Abstract Background Visceral white adipose tissue (WAT hypertrophy, adipokine production, inflammation and fibrosis are strongly associated with obesity, but the time-course of these changes in-vivo are not fully understood. Therefore, the aim of this study was to establish the time-course of changes in adipocyte morphology, adipokines and the global transcriptional landscape in visceral WAT during the development of diet-induced obesity. Results C57BL/6 J mice were fed a high-fat diet (HFD or normal diet (ND and sacrificed at 8 time-points over 24 weeks. Excessive fat accumulation was evident in visceral WAT depots (Epidydimal, Perirenal, Retroperitoneum, Mesentery after 2–4 weeks. Fibrillar collagen accumulation was evident in epidydimal adipocytes at 24 weeks. Plasma adipokines, leptin, resistin and adipsin, increased early and time-dependently, while adiponectin decreased late after 20 weeks. Only plasma leptin and adiponectin levels were associated with their respective mRNA levels in visceral WAT. Time-course microarrays revealed early and sustained activation of the immune transcriptome in epididymal and mesenteric depots. Up-regulated inflammatory genes included pro-inflammatory cytokines, chemokines (Tnf, Il1rn, Saa3, Emr1, Adam8, Itgam, Ccl2, 3, 4, 6, 7 and 9 and their upstream signalling pathway genes (multiple Toll-like receptors, Irf5 and Cd14. Early changes also occurred in fibrosis, extracellular matrix, collagen and cathepsin related-genes, but histological fibrosis was only visible in the later stages. Conclusions In diet-induced obesity, early activation of TLR-mediated inflammatory signalling cascades by CD antigen genes, leads to increased expression of pro-inflammatory cytokines and chemokines, resulting in chronic low-grade inflammation. Early changes in collagen genes may trigger the accumulation of ECM components, promoting fibrosis in the later stages of diet-induced obesity. New therapeutic approaches

    Depot medroxyprogesterone acetate (DMPA) prevents follicular maturation and ovulation, resulting in oestrogen deficiency. Oestrogen deficiency is particularly concerning as it is associated with decreases in bone mineral density (BMD) or bone mass. Widespread use of concurrent oestrogen or bisphosphonates with DMPA has been observed in a previous single-centre US study. The authors also reported that more than half of obstetrician-gynaecologists ordered BMD testing solely due to DMPA. The small sample size of the survey, potential for volunteer bias and recall bias limit the utility of this study. Given the study limitations, we sought to examine the trends of concurrent bone mineral density (BMD) testing, and bisphosphonate (BPA) and oral oestrogen-only (EST) prescribing during depot medroxyprogesterone (DMPA) use in a large administrative database. From IMS Health LifeLink™ database (2001-2013), we identified DMPA and combined hormonal contraceptive (CHC) users as women with no contraceptive claim 6 months before and after the defined episode. We examined concurrent use as the proportion of BPA or EST claims and concurrent therapy days during contraception use. We also determined the proportion of users who had a concurrent BMD test by calendar year. We identified 203 477 DMPA episodes associated with 600 BPA and 7060 EST claims and 1 297 806 CHC episodes associated with 2792 BPA and 145 600 EST claims. Most concurrent BPA use overlapped with 10% or less of the DMPA episode, whereas most concurrent BPA use overlapped with >90%-100% of CHC episode. No difference was noted with concurrent EST use. Concurrent BMD testing was higher among DMPA users (0.68%) compared to CHC users (0.11%). Across calendar year, BMD testing peaked in 2004 and declined steadily to the baseline. Most DMPA concurrent BPA (69.3%) users had a BMD test. Our findings indicate the absence of BST or EST use solely due to DMPA initiation and present alternative explanations. Published

    This analysis evaluates the 2-year effectiveness and safety of lanreotide depot/autogel (LAN), as well as treatment convenience and acromegaly symptom relief, from the Somatuline(®) Depot for Acromegaly (SODA) registry, a post-marketing, open-label, observational, multicenter, United States registry study. Patients with acromegaly treated with LAN were eligible for enrollment. Demographics, LAN dose, extended dosing interval (EDI) (interval of injections ≥42 days), insulin-like growth factor 1 (IGF-1), growth hormone (GH), glycated hemoglobin, adverse events (AEs), injection convenience, and symptom data were collected. As of September 29, 2014, 241 patients were enrolled in SODA. IGF-1 levels below age- and gender-adjusted upper normal limit (ULN) were achieved in 71.2% at month (M) 12 and 74.4% at M24; GH ≤2.5 µg/L in 83.3% at M12 and 80.0% at M24; GH <1.0 µg/L in 61.7% at M12 and 61.4% at M24. Both IGF-1 < ULN and GH ≤2.5 µg/L were achieved in 65.0% at M12 and 54.8% at M24; both IGF-1 < ULN and GH < 1.0 µg/L were achieved in 51.7 and 42.9% at M12 and M24, respectively. EDI regimen was 5.0% at baseline and 12.0% at M24. At M24, acromegaly symptoms appeared stable or improved. The most common AE was arthralgia (25.7%). Among 106 serious AEs reported by 42 patients, 10 were deemed related to therapy in 9 patients. At M24, 73.1% of patients rated LAN as convenient. SODA indicates 2-year biochemical control with majority of patients achieving both IGF-1 < ULN and GH ≤2.5 µg/L. LAN was generally well tolerated with no new or unexpected safety signals reported during the observation period. clinicaltrials.gov Clinical Trial Identifier: NCT00686348.

    The aim of the present research was to describe characteristics of adipose tissue lipolysis in dairy cows with a variable body condition score (BCS). Ten clinically healthy Holstein Friesian cows were selected based on BCS and euthanized 10 to 13 d before the expected parturition date. Immediately after euthanasia, adipose tissue samples were collected from subcutaneous and omental fat depots. In both depots, we observed an increase in adipocyte size with increasing BCS. Using an in vitro explant culture of subcutaneous and omental adipose tissue, we aimed to determine the influence of adipocyte size and localization of adipose depot on the lipolytic activity in basal conditions and after addition of isoproterenol (nonselective β-agonist) and insulin in different concentrations. Glycerol release in the medium was used as a measure for lipolytic activity. We observed that the basal lipolytic activity of subcutaneous and omental adipose tissue increased with adipocyte volume, meaning that larger fat cells have higher basal lipolytic activity independent of the location of the adipose depot. Dose-response curves were created between the concentration of isoproterenol or insulin and the amount of glycerol released. The shape of the dose-response curves is determined by the concentration of isoproterenol and insulin needed to elicit the half-maximal effect and the maximal amount of stimulated glycerol release or the maximal inhibitory effect of insulin. We observed that larger fat cells released more glycerol upon maximal stimulation with isoproterenol and this was more pronounced in subcutaneous adipose tissue. Additionally, larger fat cells had a higher sensitivity toward lipolytic signals. We observed a trend for larger adipocytes to be more resistant to the maximal antilipolytic effect of insulin. The insulin concentration needed to elicit the half-maximal inhibitory effect of insulin was within the physiological range of insulin and was not influenced by adipocyte

    The aim of this study was to compare the clinical performance of depot medroxyprogesterone acetate (DMPA) in women who received injections every 3 months at the Family Planning Clinic, and those who received every other injection at a health care facility near their place of residence, only returning to the clinic every 6 months. The medical charts of DMPA users from 2 January 1980 through 31 December 2012 were evaluated for this study. Two cohorts of women were created and compared: those who regularly received DMPA injections every 3 months (3-month group) at the clinic and those who received alternating 3-month injections at a health care facility near their residence house, returning to the clinic every 6 months for an injection (6-month group). In addition, effectiveness rates, reasons for discontinuation, and continuation rates were evaluated. Overall, 2637 women received all injections at 3-month intervals at the clinic, and 1190 women received every other injection at a health care facility near their residence. The women in the 3-month group had higher pregnancy rates and higher discontinuation rates (with the exception of discontinuation due to the loss of libido). The women who received alternating injections near their homes were more likely to continue using DMPA as a contraception method and presented lower pregnancy and discontinuation rates (for the majority of reasons), when compared to those women who returned to the clinic every 3 months.

    Background Depot-medroxyprogesterone acetate (DMPA), norethisterone enanthate (NET-EN) and combined oral contraceptives (COCs) have been shown to have a negative effect on bone mineral density (BMD) in adolescents. The aim of this study was to investigate BMD in 15-to 19-year-old new users of DMPA, NET-EN and COCs. Study Design This 5-year longitudinal study followed-up new users of DMPA (n=115), NET-EN (n=115), and COCs (n=116), and 144 nonuser controls. BMD was measured at the distal radius using dual x-ray absorptiometry. Results BMD increased in all groups (annual percent increase: nonusers, 1.49%; DMPA, 1.39%; NET-EN, 1.03%; COCs, 0.84%) during follow-up (p<0.001). There was evidence for lower BMD increases per annum in NET-EN (p=.050) and COC (p=.010) users compared to nonusers but no difference between DMPA and nonusers (p=.76). In 14 NET-EN discontinuers, an overall reduction of 0.61% per year BMD was followed upon cessation by an increase of 0.69% per year (p=.066). Conclusion This study suggests that BMD increases in adolescents may be less in NET-EN and COC users; however, recovery of BMD in NET-EN users was found in the small sample of adolescents followed post-discontinuation.

    This randomized double-blind study, with 24-week treatment and 24-week posttreatment periods, evaluated the effects of elagolix (150 mg every day, 75 mg twice a day) versus subcutaneous depot medroxyprogesterone acetate (DMPA-SC) on bone mineral density (BMD), in women with endometriosis-associated pain (n = 252). All treatments induced minimal mean changes from baseline in BMD at week 24 (elagolix 150 mg: -0.11%/-0.47%, elagolix 75 mg: -1.29%/-1.2%, and DMPA-SC: 0.99%/-1.29% in the spine and total hip, respectively), with similar or less changes at week 48 (posttreatment). Elagolix was associated with improvements in endometriosis-associated pain, assessed with composite pelvic signs and symptoms score (CPSSS) and visual analogue scale, including statistical noninferiority to DMPA-SC in dysmenorrhea and nonmenstrual pelvic pain components of the CPSSS. The most common adverse events (AEs) in elagolix groups were headache, nausea, and nasopharyngitis, whereas the most common AEs in the DMPA-SC group were headache, nausea, upper respiratory tract infection, and mood swings. This study showed that similar to DMPA-SC, elagolix treatment had minimal impact on BMD over a 24-week period and demonstrated similar efficacy on endometriosis-associated pain. © The Author(s) 2014.

    Full Text Available Many family planning program focus more on men. Until now, vasectomy has been the commonly used method for male contraception. However, this method creates inconvenience such as irreversibility and psychological problems. One of the alternatives contraception is the combination of depot medroxyprogesterone acetate (DMPA and androgen. The minimum dosage of DMPA could suppress testosterone level that leads to reduced spermatogenesis and sperm viability. Nevertheless, until now it is not known whether minimum dosages of DMPA have an effect to body weight and blood chemistry. Therefore, this research aimed at determinate the effect of minimal dosages of DMPA to body mass and blood chemistry using male rats (Rattus norvegicus L. strain Sprague-Dawley as model. This research using completely randomized design, unequal size sample, castration treatments and several doses DMPA (1.25, 0.625, and 0.313 milligram. Injecting of DMPA conducted intramuscularly on week 0 and week 12. Normality/homogeneity Data normality were analyzed before ANOVA test. Then, abnormal data were tested using Kruskal-Wallis test. The result shows that injection of DMPA in various doses do not have an effect on body weight and blood chemistry such as erytrocytes, haemoglobin, hematocrite, HDL, LDL, total cholesterol, SGOT, SGPT and triglyseride (p>0,05. Furthermore, it is concluded that that no effect of minimal dosages of DMPA to body mass and blood chemistry of rat.

    To evaluate weight gain and body composition (BC) in new users of depot-medroxyprogesterone acetate (DMPA) as a contraceptive. This cohort study followed up 20 DMPA users and 20 copper intrauterine device (TCu380A IUD) users, paired for age (± 1 year) and body mass index (BMI ± 1 kg/m(2)), during 12-months. Healthy, non-obese women aged 18 to 40 years, unaffected by conditions that could influence their body weight, were enrolled. Socio-demographic variables, habits, weight, BMI, BC using dual-energy X-ray absorptiometry, circumferences, skinfold thickness, body fat percentage and waist-to-hip ratio were evaluated. All participants were encouraged to adopt healthy habits. At baseline, median age was 29 and 30.5 years, and mean BMI was 24.8 and 24.5 kg/m(2) in the DMPA and IUD groups, respectively. At 12 months, an increase was observed in waist and hip circumference in the DMPA users and 8/20 of them had a weight gain ≥ 5% (mean 4.6 kg) with accumulation of fat centrally. There were no differences in weight gain or in BC measurements between the groups; nevertheless 40% of women in the DMPA group had larger weight gain and accumulation of fat centrally. The duration of follow-up may have been insufficient to detect differences between the groups.

This three-year prospective observational study included 102 women using LNG-IUS and 104 women using DMPA for contraception. Participants were followed at regular intervals over three years with performance of transvaginal ultrasound to measure uterine artery pulsatility index (PI) and resistance index (RI) before starting the method and at six months, 12 months, two and three years thereafter. Data was collected and tabulated. Significant changes in uterine artery PI and RI were detected. PI indices were reduced after six months of use in both groups and elevated significantly at 12 months in both groups compared to initial values (p < .001) while RI significantly reduced after six months in both groups and elevated significantly at 12 months, two and three years in both groups compared to initial values (p < .001). Both PI and RI significantly reduced in women suffered abnormal uterine bleeding and significantly elevated in women experienced amenorrhea irrespective of the method used (p < .001). LNG-IUS and DMPA induce hemodynamic changes in the uterine arteries denoting positive correlation with menstrual irregularities. Larger multicentre studies are warranted to potentiate our findings.

    Intravaginal rings (IVR) for HIV prevention will likely be used by women on depot medroxyprogesterone acetate (DMPA) hormonal contraception. We used pigtailed macaques to evaluate the effects of DMPA on tenofovir disoproxil fumarate (TDF) IVR pharmacokinetics and viral shedding. Mucosal tenofovir (TFV) levels were compared in SHIVSF162p3 -negative DMPA-treated (n=4) and normally cycling (n=6) macaques receiving TDF IVRs. Plasma viremia and vaginal shedding were determined in groups of SHIVSF162p3 -positive DMPA-treated (n=6) and normally cycling (n=5) macaques. Similar median vaginal fluid TFV concentrations were observed in the DMPA-treated and cycling macaques over 4 weeks (1.2×10(5) and 1.1.×10(5)  ng/mL, respectively). Median plasma viremia and vaginal shedding AUC of the DMPA-treated (2.73×10(7) and 8.15×10(4) copies/mL, respectively) and cycling macaques (3.98×10(7) and 1.47×10(3) copies/mL, respectively) were statistically similar. DMPA does not affect TDF IVR pharmacokinetics or SHIV shedding. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Aim. To evaluate whether body fat distribution, birth weight, and family history for diabetes (FHD were associated with metabolic syndrome (MetS in children and adolescents. Methods. A total of 439 Italian obese children and adolescents (5–18 years were enrolled. Subjects were divided into 2 groups: prepubertal and pubertal. MetS was diagnosed according to the adapted National Cholesterol Education Program criteria. Birth weight percentile, central obesity index (measured by dual-energy X-ray absorptiometry, insulin sensitivity (ISI, and disposition index were evaluated. Multivariate logistic regression models were used to determine variables associated with MetS. Results. The prevalence of MetS was 17%, with higher percentage in adolescents than in children (21 versus 12%. In the overall population, central obesity index was a stronger predictor of MetS than insulin sensitivity and low birth weight. When the two groups were considered, central fat depot remained the strongest predictor of MetS, with ISI similarly influencing the probability of MetS in the two groups and birth weight being negatively associated to MetS only in pubertal individuals. Neither FHD nor degree of fatness was a significant predictor of MetS. Conclusion. Simple clinical parameters like increased abdominal adiposity and low birth weight could be useful tools to identify European obese adolescents at risk for metabolic complications.

    Subcritical cryogens such as liquid hydrogen (LH2) and liquid oxygen (LO2) are required for space based transportation propellant, reactant, and life support systems. Future long-duration space missions will require on-orbit systems capable of long-term cryogen storage and efficient fluid transfer capabilities. COLD-SAT, which stands for cryogenic orbiting liquid depot-storage acquisition and transfer, is a free-flying liquid hydrogen management flight experiment. Experiments to determine optimum methods of fluid storage and transfer will be performed on the COLD-SAT mission. The success of the mission is directly related to the type and accuracy of measurements made. The instrumentation and measurement techniques used are therefore critical to the success of the mission. This paper presents the results of the COLD-SAT experiment subsystem instrumentation and wire harness design effort. Candidate transducers capable of fulfilling the COLD-SAT experiment measurement requirements are identified. Signal conditioning techniques, data acquisition requirements, and measurement uncertainty analysis are presented. Electrical harnessing materials and wiring techniques for the instrumentation designed to minimize heat conduction to the cryogenic tanks and provide optimum measurement accuracy are listed.

  20. The Washington Needle Depot: fitting healthcare to injection drug users rather than injection drug users to healthcare: moving from a syringe exchange to syringe distribution model

    2010-01-01

    Full Text Available Abstract Needle exchange programs chase political as well as epidemiological dragons, carrying within them both implicit moral and political goals. In the exchange model of syringe distribution, injection drug users (IDUs must provide used needles in order to receive new needles. Distribution and retrieval are co-existent in the exchange model. Likewise, limitations on how many needles can be received at a time compel addicts to have multiple points of contact with professionals where the virtues of treatment and detox are impressed upon them. The centre of gravity for syringe distribution programs needs to shift from needle exchange to needle distribution, which provides unlimited access to syringes. This paper provides a case study of the Washington Needle Depot, a program operating under the syringe distribution model, showing that the distribution and retrieval of syringes can be separated with effective results. Further, the experience of IDUs is utilized, through paid employment, to provide a vulnerable population of people with clean syringes to prevent HIV and HCV.

    Methods.  In a cross-sectional substudy of the Multicenter AIDS Cohort Study, noncontrast cardiac computed tomography (CT) scanning for coronary artery calcium (CAC) scoring was performed on all men, and, for men with normal renal function, coronary CT angiography (CTA) was performed. Associations between fat depots (visceral adipose tissue [VAT], abdominal subcutaneous adipose tissue [aSAT], and thigh subcutaneous adipose tissue [tSAT]) with coronary plaque presence and extent were assessed with logistic and linear regression adjusted for age, race, cardiovascular disease (CVD) risk factors, body mass index (BMI), and human immunodeficiency virus (HIV) parameters. Results.  Among HIV-infected men (n = 597) but not HIV-uninfected men (n = 343), having greater VAT was positively associated with noncalcified plaque presence (odds ratio [OR] = 1.04, P aSAT and tSAT and greater median VAT among men with BMI aSAT and extent of total plaque among HIV-infected men, but not among HIV-uninfected men. Lower tSAT was associated with greater CAC and total plaque score extent regardless of HIV serostatus. Conclusions.  The presence of greater amounts of VAT and lower SAT may contribute to increased risk for coronary artery disease among HIV-infected persons.

    Patients with diabetes mellitus are prone to develop refractory wounds. They exhibit reduced synthesis and levels of circulating hydrogen sulfide (H2S), which is an ephemeral gaseous molecule. Physiologically, H2S is an endogenous gasotransmitter with multiple biological functions. An emulsion method is utilized to prepare a microparticle system that comprises phase-change materials with a nearly constant temperature of phase transitions to encapsulate sodium hydrosulfide (NaHS), a highly water-labile H2S donor. An emulsion technique that can minimize the loss of water-labile active compounds during emulsification must be developed. The as-prepared microparticles (NaHS@MPs) provide an in situ depot for the sustained release of exogenous H2S under physiological conditions. The sustained release of H2S promotes several cell behaviors, including epidermal/endothelial cell proliferation and migration, as well as angiogenesis, by extending the activation of cellular ERK1/2 and p38, accelerating the healing of full-thickness wounds in diabetic mice. These experimental results reveal the strong potential of NaHS@MPs for the sustained release of H2S for the treatment of diabetic wounds. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The Depot-Logistic Information Management System (DLIMS is aimed to provide the Air Force logistics staff of all sectors with an information technology platform for convenience of management, supervision, aircraft maintenance, along with supply operations. The DLIMS in Taiwan has been established for more than 10 years. However, it has not been evaluated for its effectiveness. This study integrates service quality into Wixom and Todd [1] model to evaluate the effectiveness of the DLIMS. A survey of 273 users of DLIMS was conducted to validate the proposed model. The research results show that the overall goodness-of-fit indices indicate a reasonable fit of the model and data. This study emphasizes the importance of integration of satisfaction theory and technology acceptance theory to comprehensively illustrate the effectiveness of DLIMS. The integrative viewpoint implies that DLIMS is not only a logistic information system but also a service provider to the Air Force. Accordingly, the professional staff officers IS department, logistics sectors and headquarters should value simultaneously object-based functions and service quality, in order to improve users’ satisfaction, which in turn can promote users’ behavioral beliefs and usage intention. The findings can be a reference for the Air Force logistics sectors to make policies as well as be a basis for evaluation of success and acceptance of military-related information system.

  4. Observations of the smoke plume from the December 2005 explosions and prolonged oil fire at Buncefield oil depot, southern UK and associated atmospheric changes

    The explosions and subsequent fire at the Buncefield oil depot in December 2005 afforded a rare opportunity to study the atmospheric consequences of a major oil fire at close range, using ground-based remote sensing instruments. The fire burned 5.6 × 107kg of refined fuel (unleaded petrol, aviation fuel and diesel) over 3 days and produced a plume of smoke that extended over much of southern England. Near-source measurements suggest that plume particles were ~50% black carbon (BC) with refractive index 1.73-0.42i, effective radius (Reff) 0.45-0.85μm and mass loading ~2000μg.m-3. About 50km downwind, particles were ~60-75% BC with refractive index between 1.80-0.52i and 1.89-0.69i, Reff ~1.0μm and mass loadings 320-780μg.m-3. Number distributions were almost all monomodal with peak at rgas concentrations of SO2 (70ppb), NO2 (140ppb), HONO (20ppb), HCHO (160ppb) and CS2 (40ppb). We estimate that the Buncefield event emitted totals of ~6.3, 7.2 and 5.5Mg of SO2, HCHO and CS2 respectively; along with ~5500Mg of BC. Our measurements are consistent with others of the Buncefield plume, and with studies of the 1991 Kuwaiti oil-fire plumes; differences from the latter reflecting in part a contrast in source composition (refined fuels vs. crude oils) leading to important potential differences in atmospheric impacts. Measurements made as the plume passed overhead ~50km downwind showed a reduced solar flux reaching the surface but little effect on the atmospheric potential gradient. The wind speed data from the day of the explosion hints at a possible explosion signature.

    Data on record regarding weight variation in depot-medroxyprogesterone acetate (DMPA) and levonorgestrel-releasing intrauterine system (LNG-IUS) users are controversial. To date, no studies have yet evaluated weight variation in DMPA and LNG-IUS users in up to ten years of use compared to non-hormonal contraceptive users. A retrospective study analysed weight variations in 2138 women using uninterruptedly DMPA (150 mg intramuscularly, three-monthly; n = 714), the LNG-IUS (n = 701) or a copper-intrauterine device (Cu-IUD; n = 723). At the end of the first year of use, there was a mean weight increase of 1.3 kg, 0.7 kg and 0.2 kg among the DMPA-, LNG-IUS- and Cu-IUD users, respectively, compared to weight at baseline (p < 0.0001). After ten years of use, the mean weight had risen by 6.6 kg, 4.0 and 4.9 kg among the DMPA-, LNG-IUS- and Cu-IUD users, respectively. DMPA-users had gained more weight than LNG-IUS- (p = 0.0197) and than Cu-IUD users (p = 0.0294), with the latter two groups not differing significantly from each other in this respect (p = 0.5532). Users of hormonal and non-hormonal contraceptive methods gained a significant amount of weight over the years. DMPA users gained more weight over the treatment period of up to ten years than women fitted with either a LNG-IUS or a Cu-IUD.

    The aim of this study was to evaluate for 12 months the changes of body weight using Depot Medroxyprogesterone Acetate (DMPA) and if these changes are related to inflammatory markers. Twenty women of childbearing age who chose the DMPA, without previous use of this method, BMI < 30 kg/m2, and 17 women using IUD TCu 380A, participated in the study. At the baseline and after one year, changes in weight gain, body composition by the bioimpedance electric method, resting energy expenditure (REE) by the indirect calorimetry method, inflammatory markers and HOMA-IR were assessed. After 12 months of evaluation, we could observe a significant increase in the DMPA group in weight (3,01 kg) and BMI, while the IUD group's only significant increase was observed in the BMI. Relative to REE there was an increase of basal metabolic rate (BMR) in both groups after one year. The sub-group DMPA that gained < 3 kg had increased significant weight, BMI and body surface (BS) with respiratory quotient (RQ) reduction, while the sub-group that gained ≥ 3 kg had a significant increase in weight, BMI, BS, fat-free mass, fat mass, BMR, Leptin, HOMA-IR and waist circumference, with RQ significantly reduced. Our study found significant changes in weight, body composition and metabolic profile of the population studied in the first 12 months of contraceptive use. These changes mainly increased body weight, leptin levels and HOMA-IR which can contribute to the development of some chronic complications, including obesity, insulin resistance and diabetes mellitus.

    Activation of brown adipose tissue (BAT) and browning of white adipose tissue (WAT) present potential new therapies for obesity and type 2 diabetes. Here, we examined the effects of β3-adrenergic stimulation on tissue-specific uptake and storage of free fatty acids (FFA) and its implications for whole body FFA metabolism in diet-induced obese rats using a multi-radiotracer technique. Male Wistar rats were high fat-fed for 12 wk and administered β3-agonist CL316,243 (CL, 1 mg·kg(-1)·day(-1)) or saline via osmotic minipumps during the last 3 wk. The rats were then fasted and acutely infused with a tracer mixture ([(14)C]palmitate and the partially metabolized R-[(3)H]bromopalmitate) under anesthesia. CL infusion decreased body weight gain and fasting plasma glucose levels. While core body temperature was unaffected, infrared thermography showed an increase in tail heat dissipation following CL infusion. Interestingly, CL markedly increased both FFA storage and utilization in interscapular and perirenal BAT, whereas the flux of FFA to skeletal muscle was decreased. In this rat model of obesity, only sporadic populations of beige adipocytes were detected in the epididymal WAT depot of CL-infused rats, and there was no change in FFA uptake or utilization in WAT following CL infusion. In summary, β3-agonism robustly increased FFA flux to BAT coupled with enhanced utilization. Increased BAT activation most likely drove the increased tail heat dissipation to maintain thermostasis. Our results emphasize the quantitative role of brown fat as the functional target of β3-agonism in obesity. Copyright © 2016 the American Physiological Society.

    In patients with multiple endocrine neoplasia type 1 (MEN1), expression of somatostatin receptor (SST) in parathyroid adenomas and effectiveness of therapy with somatostatin analogues on primary hyperparathyroidism (PHP) have been scarcely investigated. To evaluate the effects of depot long acting octreotide (OCT-LAR) in patients with MEN1-related PHP. Eight patients with a genetically confirmed MEN1, presenting both PHP and duodeno-pancreatic neuroendocrine tumours (NET), were enrolled. The initial treatment was OCT-LAR 30 mg every 4 weeks. This therapy was established to stabilize the duodeno-pancreatic NET before to perform parathyroidectomy for PHP. Before OCT-LAR therapy, a SST scintigraphy was performed in all patients. SST subtype 2A immunohistochemistry was performed on parathyroid tumour samples from three patients undergone parathyroidectomy after OCT-LAR therapy. Serum concentrations of PTH, calcium and phosphorus as well as the 24-h urine calcium : creatinine ratio and the renal threshold phosphate concentration were evaluated before and after OCT-LAR. After OCT-LAR therapy, hypercalcaemia and hypercalciuria normalized in 75% and 62.5% of patients, respectively, and serum phosphorus and renal threshold phosphate significantly increased. Serum PTH concentrations significantly decreased in all patients and normalized in two of them. SST subtype 2A immunostaining was found in all parathyroid adenomas investigated, while SST scintigraphy showed a positive parathyroid tumour uptake in three of eight patients (37.5%). Six months of OCT-LAR therapy controlled hypercalcaemia and hypercalciuria in two-thirds of patients with MEN1-related PHP. Direct OCT-LAR effects mediated by binding to SST expression on parathyroid tumour cells are likely the main mechanism to explain the activity of this compound on calcium and phosphorus abnormalities in MEN1 PHP.

    Full Text Available Background: Smoking has deleterious effects on breath-holding time (BHT, which has been used in respiratory physiology as a measure of ventilatory response. Evidences regarding assessment of the reversibility of the impact of smoking on BHT and recovery in ex-smokers are ambiguous. Hence, this study was conducted to quantify the reduction in BHT and to assess the reversibility of the same. Materials and Methods: A cross-sectional study was conducted on 84 bus-depot workers consisting of equal number of smokers, ex-smokers, and non-smokers. Breath-holding time was recorded using the mouth piece attached to the mercury manometer where the subjects were advised to blow through the mouth piece after full inspiration as long as possible till the breaking point following standard methods and precautions. Comparisons among 3 groups were performed employing one-way ANOVA and post-hoc tests. The significance of difference in BHT between the 2 categories of frequency and duration of smoking was tested using Student′s t-test for independent samples. Results: BHT was found to be significantly reduced among smokers compared to non-smokers. Almost complete recovery of BHT was observed in ex-smokers. There was deterioration in BHT with increase in BMI, and a statistically significant negative correlation was observed when BHT was correlated with age, especially in smokers. Conclusion: Present study has demonstrated considerable reduction of BHT in smokers and indications of recovery in ex-smokers. Further detailed study with larger sample size, stricter definition of ex-smokers, and considering physical activity is recommended.

    To determine weight variation in women with different Body Mass Index (BMI) in use of trimestral injections of depot-medroxyprogesterone acetate (DMPA), and compare it to women users of a non-hormonal method. Retrospective study with the chart review of 226 DMPA users and 603 controls, users of DIU TCu380A. Women were distributed in categories, according to their initial BMI, as having normal weight (or=30 kg/m(2)), and were followed-up for six years, with yearly measurements of weight and BMI. The statistic test ANOVA was used to measure the weight variation among the groups in each BMI category every year. The average age at the onset of the method employed was higher in the study group than in the controls, in all the BMI categories: 31.6+/-SD 7.1 X 27.4+/-SD 5.5 in the normal weight category (p<0.0001); 37.3+/-SD 6.8 X 29.2+/-SD 6.0 in the overweight category (p<0.0001); and 35.3+/-SD 6.4 X 29.7+/-SD 5.8 among obese women (p<0.0001). DMPA users showed weight increase as compared to the controls in the overweight category (p=0.0082); and the weight increase along the observation period was also higher among the DMPA users than among the controls, for the normal weight (p<0.0001) and overweight (p=0.0008) categories. In the obese group, there was no BMI variation between the groups, nor along the period during which they were using the method. There was no change in weight gain among DMPA users from the obese category. Prospective studies should be done with metabolic tests to establish the determining factors of weight gain in normal and overweight women.

  12. Longitudinal profiling of the tissue-specific expression of genes related with insulin sensitivity in dairy cows during lactation focusing on different fat depots.

    Directory of Open Access Journals (Sweden)

    Behnam Saremi

    Full Text Available In dairy cows the milk associated energy output in early lactation exceeds the input via voluntary feed intake. To spare glucose for mammary lactose synthesis, peripheral insulin sensitivity (IS is reduced and fat mobilization is stimulated. For these processes a link between IS and the endocrine functions of adipose tissue (AT is likely; we thus aimed to characterise the mRNA expression from bovine AT derived proteins and receptors that are related to IS according to the literature in metabolically active tissues plus systemic IS throughout lactation. Conjugated linoleic acids (CLA reduce milk fat thus decreasing the milk drain of energy and potentially dampening lipolysis, but may also affect IS. Subcutaneous (s.c. AT and liver from pluriparous cows receiving either control fat or CLA supplement (100 g/day from 1 to 182 days in milk each were biopsied covering week -3 to 36 relative to parturition. In an additional trial with primiparous cows treated analogously and slaughtered on days in milk 1, 42 or 105, samples from liver, udder, skeletal muscle and 3 visceral and 3 s.c. AT were obtained and assayed for mRNA abundance of adiponectin, its receptors, leptin, leptin receptor, PPARγ, PPARγ2, IL-6, and TNF-α. In pluriparous animals, the mRNA abundance of most of the target genes decreased after parturition in s.c. AT but increased in liver. In primiparous cows, AT depot specific differences were mostly related to retroperitoneal AT; adiponectin receptor 1 and TNF-α were affected predominantly. CLA effects in primiparous cows were largely limited to decreased PPARγ2 mRNA abundance in udder tissue. In pluriparous cows, insulin secretion was increased by CLA resulting in decreased systemic IS but without consistent changes in tissue target mRNA abundance. The temporal gene expression profiles from the adipokines and related receptors support their coactive function in adapting to the needs of lactation.

    Ruminants rely on short-chain fatty acids (SCFA) as principal energy source. Herein, we compared the effects of propionate, β-hydroxybutyrate (BHB) and insulin on mRNA abundance of energy balance-related genes by short-term incubation (4 h) in bovine subcutaneous (SC) and retroperitoneal (RP) adipose tissue (AT) explants in vitro. Propionate either significantly (p genes such as adiponectin system in both depots in treated samples versus controls. Propionate increased adiponectin receptor 1 (AdipoR1) and AdipoR2 mRNA only in SC AT. β-hydroxybutyrate decreased mRNA abundance of adiponectin and AdipoR1 in SC AT as a trend. The mRNA abundance of free fatty acid receptor 2/3 (FFAR2/3) and other genes of interest (GOI) was increased during differentiation in bovine preadipocyte culture. The mRNA abundance of all the GOI remained unchanged after short-term insulin stimulation. In total, propionate, BHB or insulin during short-term treatment exert divergent effects on the mRNA abundance of GOI in both depots in vitro. Our results indicate that the bovine adiponectin system might be more sensitive to propionate than to BHB. We demonstrated the presence of FFAR2/3 mRNA not only in both AT depots but also in differentiating preadipocytes isolated from bovine SC AT. Therefore, we established that SCFA are able to exert insulin-independent effects on bovine adipose tissue, which might be independent from propionate uptake-related events. © 2011 Blackwell Verlag GmbH.

    Intra-articular injection (IAI) of both hyaluronic acid (HA) and depot-steroid preparations had the advantage of quick and prolonged favorable effects on pain relief among patients with symptomatic osteoarthritis of the knee (OAK). The effect of IAI of HA on the systemic effects of the intra-articular steroids had not been investigated. Non-selected patients attending the rheumatology clinic with symptomatic OAK who failed NSAIDS and physical therapy were offered an IAI of HA at the knee joint followed 20 min later by an IAI of 1 ml of Celestone Chronodose at the same joint (group 1). Morning serum levels of cortisol were obtained just prior to the IAI and 1, 2 and 8 days later. Demographic, clinical, and laboratory parameters were obtained also from all the patients. Age- and sex-matched group of patients from the same clinic were recruited as a control group (group 2). Mean baseline serum cortisol levels in group 1 was 381 ± 154 mmol/l vs. 376 ± 119 in group 2 (p = 0.954). Morning serum cortisol levels at day 1 and day 2 were 24 ± 6 and 22 ± 6 mmol/l, respectively, in group 1 patients vs. 27 ± 5.8 (p = 0.214) and 25 ± 5.6 mmol/l (p = 0.200), respectively, in group 2. These levels were significantly lower than baseline levels in each group. Morning serum cortisol levels at day 8 in group 1 and group 2 were 349 ± 128 and 314 ± 99 mmol/l, respectively (p = 0.419). Pre-injection of HA at the knee joint did not affect the systemic effect on the hypothalamic-pituitary-adrenal axis of IAI of Celestone Chronodose.

    Vitamin A and its metabolites are known to modulate adipose tissue development and its associated complications. Here, we assessed the vitamin A status and its metabolic pathway gene expression in relation to sexual dimorphism by employing 35 days old C57BL/6J male and female mice, which were fed either stock or high fat (HF) diet for 26 weeks. HF diet feeding increased body weight/weight gain and white adipose tissue (WAT) of visceral and subcutaneous regions, however, increase in vitamin A levels observed only in subcutaneous WAT. Further, the expression of most of the vitamin A metabolic pathway genes showed no sexual dimorphism. The observed HF diet-induced hyperglycaemia in male corroborates with increased retinol binding protein 4 (RBP4) levels in plasma and its expression in visceral adipose depots. In conclusion, the male mice are susceptible to high fat diet-induced hyperglycaemia and display higher plasma RBP4 levels, possibly due to its over-expression in visceral adipose depots.

    As part of an environmental investigation at Fort Wingate Depot Activity, New Mexico, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, interpreted aqueous geochemical concentrations to better understand the groundwater flow paths and the fate and transport of constituents of concern in the alluvial aquifer underlying the study area. The fine-grained nature of the alluvial matrix creates a highly heterogeneous environment, which adds to the difficulty of characterizing the flow of groundwater and the fate of aqueous constituents of concern. The analysis of the groundwater geochemical data collected in October 2009 provides evidence that is used to identify four groundwater flow paths and their extent in the aquifer and indicates the dominant attenuation processes for the constituents of concern. The extent and interaction of groundwater flow paths were delineated by the major ion concentrations and their relations to each other. Four areas of groundwater recharge to the study area were identified based on groundwater elevations, hydrogeologic characteristics, and geochemical and isotopic evidence. One source of recharge enters the study area from the saturated alluvial deposits underlying the South Fork of the Puerco River to the north of the study area. A second source of recharge is shown to originate from a leaky cistern containing production water from the San Andres-Glorieta aquifer. The other two sources of recharge are shown to enter the study area from the south: one from an arroyo valley draining an area to the south and one from hill-front recharge that passes under the reported release of perchlorate and explosive constituents. The spatial extent and interaction of groundwater originating from these various sources along identified flow paths affect the persistence and attenuation of constituents of concern. It was determined that groundwater originating in the area of a former explosives’ wash-out operation and an

  16. Attack, parry and riposte: molecular fencing between the innate immune system and human herpesviruses.

    Le-Trilling, V T K; Trilling, M

    2015-07-01

    Once individuals acquire one of the eight human-pathogenic herpesviruses, the upcoming relationship is predefined to last lifelong. Despite the fact that acute phases of herpesviral replication are usually confined and controlled by a concerted action of all branches of the healthy immune system, sterile immunity is never reached. To accomplish this, herpesviruses evolved the unique ability to outlast episodes of efficient immunity in a dormant state called latency and a remarkable array of immune antagonists which counteract most (if not all) relevant aspects of intrinsic, innate and adaptive immune responses. Certain psychological and physiological conditions (such as stress, immuno-suppression or pregnancy) predispose for viral reactivation which can lead to recurrent disease and virus spread. One important pillar of immunity is the innate immune system. The leading cytokines of the innate immune response are interferons (IFN). IFNs reinforce intrinsic immunity, induce a cell-intrinsic antiviral state and recruit and orchestrate adaptive immunity. Consistently, individuals lacking a functional IFN system suffer from otherwise harmless opportunists and live-attenuated vaccines. The selective pressure elicited by IFNs drove herpesviruses to evolve numerous IFN antagonistic gene products. A molecular in-depth understanding of (herpes-) viral IFN antagonists might allow the design of novel antiviral drugs which reconstitute IFN responses by blocking the antagonistic function and thereby help the host to help himself. Additionally, virus mutants lacking immune evasins constitute promising candidates for vaccine viruses. Here we summarize the current knowledge on IFN antagonistic strategies of the eight human herpesviruses and try to decipher common strategies.

    Fifty-five normal-weaned Angus steers (268 ± 22 kg; 265 ± 16 d of age) were used to evaluate the effects of starch- vs. fiber-based energy supplements for stocker cattle grazing low-quality dormant native range on growth performance, body composition, and adipose tissue development of different fat depots. Steers were randomly allotted to 4 treatments: 1.02 kg·steer(-1)·d(-1) of a 40% CP cottonseed meal-based supplement (CON), corn/soybean meal-based supplement fed at 1% of BW (CORN), soybean hull/soybean meal-based supplement fed at 1% of BW (SBH), or dried distillers grains with solubles fed at 1% of BW (DDGS). All supplements were individually fed 5 d/wk during the 121-d winter grazing phase. After winter grazing, 3 steers per treatment were harvested to determine body composition and carcass characteristics, and collect subcutaneous (SC) and perirenal (PR) adipose tissue samples. The remaining steers grazed cool-season grass pastures for 74 d without supplementation before finishing. Steers were fed a common finishing diet for 113 d before harvest, at which time carcass characteristics were collected at a commercial abattoir. Energy supplementation increased (P Energy supplementation increased (P 0.13) 12th rib fat thickness or marbling score at intermediate harvest compared with CON steers. The mRNA expression of genes involved in lipogenesis and markers of adipogenesis were greater (P energy-supplemented steers compared with CON steers but not in SC adipose tissue. Fiber-supplemented steers had greater (P energy-supplemented steers had greater (P energy supplementation nor type of energy supplement influenced intramuscular fat deposition in stocker cattle grazing dormant native range. These data suggest that the total energy intake and stage of animal maturity during grazing supplementation were not great enough to influence marbling deposition.

    Full Text Available Purpose: The purpose of the present study was to analyze the effects of green tea infusion on the toxicity of ovaries of female rats treated with the contraceptive depot-medroxyprogesterone acetate (DMPA. Material and Methods: A total of twenty-four female rats were randomly divided into four groups, incuding the control group (no treatment, the DMPA-treated group and the group treated with DMPA and infusion of green tea at various doses (165 and 330 mg/gram of body weight per day. The number of granulosa cells, the number of ovarian follicles and the size of ovarian follicles were subjected to histopathological analysis. Results: The number of granulosa cells did not differ significantly among the study groups. The number of ovarian follicles was significantly higher in the DMPA-treated group than that of the control group. Of doses of 165 and 330 mg/g of body weight of green tea administration, only the low dose decreased the number of ovarian follicles significantly relative to the DMPA-treated group, although it has not yet reached the levels comparable to those of the control group. The size of ovarian follicles did not differ significantly among the study groups. Conclusion: DMPA led to an increased number of ovarian follicles, which was restored by infusion of low doses of green tea. Thus, green tea constitutes an herb that can be combined with administration of DMPA and useful in inhibiting the adverse effects of contraceptives. [Cukurova Med J 2016; 41(4.000: 675-679

    Full Text Available The development of male hormonal contraception is based on the decrease in the sperm concentration and it does notaffect libido and sexual potency. The combination of depot medroxy progesterone acetate (DMPA + extract ofJavanese long pepper (JLP with dosages of 0.94 mg and 1.88 mg decreases the concentration of spermatozoa.However, it remains unknown whether the combination influences body weight, hematology, and blood biochemistry.Therefore, it is necessary to investigate the effect of DMPA + JLP extracts on the body weight, hematology, and bloodbiochemistry of male rats (Rattus norvegicus L. strains of Sprague-Dawley. The research uses a completelyrandomized design (CRD; one group control and two treatment groups. In the first group, the castration rats were givenoral administration extracts of JLP (CJ with doses of 0, 0.94, 1.88, 2.82, and 3.76 mg. In the second group, the ratswere injected with 1.25 mg DMPA and given an oral administration extract of JLP. Injection was given in week-0 and12. Administration was conducted every day from week 7-18. Analysis of the normality and homogeneity of data isdone before the test ANOVA. Data that is abnormal and not homogeneous are tested with non-parametric statisticalKruskal-Wallis. This study shows that the combination of minimal doses of DMPA and administration various doses ofextracts of JLP does not affect body weight and hematology (erythrocyte, hemoglobin, hematocrite, and the bloodbiochemistry of rats, such as the values of SGPT, SGOT, HDL, and triglycerides (p < 0.05, but rather the totalcholesterol and LDL (p < 0.05. Furthermore, it is concluded that the combination of the minimal dosage of DMPA andweaned various dosages of JLP extracts affect the total value and LDL cholesterol but do not influence body weight,nor hematology and blood biochemistry. Such combination can be drawn on for a male contraceptive model that is safeby taking into account the value of the total cholesterol and LDL

The algorithm for k median forest is t-swap local search, and we prove that it has locality gap 3 + 2 t ; this generalizes the corresponding result for k median [3]. Finally we consider the k median...... forest problem when there is a different (unrelated) cost function c for the MST part, i.e. the objective is Eu∈V d(u, S) + c(MST(V/S) ). We show that the locality gap for this problem is unbounded even under multi-swaps, which contrasts with the c = d case. Nevertheless, we obtain a constant...

    Background concentrations of eleven elements in tissues and organs of wild-living rats (Rattus norvegicus) obtained from a region (Euroregion Neisse, around the trilateral border region of Germany, Poland and the Czech Republic) distinguished by low to intermediate levels of environmental contaminations are given in part I of this work. In order to identify the most important depot compartments for certain elements, a body burden method was applied. Differences of affinity due to sex and age of analyzed rats are discussed, as are the suitability of specific organs and tissues with regard to bioaccumulation measurements concerning metals. The principal depot compartments for the heavy metals Cu, Mn, Cd, (in adult rats) and Tl are the liver and kidneys, whereas the elements Ni, Sr, Pb (for adult animals) and Ti are more affinitively to bones. Co and Zn displayed a more pronounced affinity towards tissues of the bones and liver. The analysis revealed large differences in Cd and Pb distributions both among young and adult rats, and with respect to sexes. It can be concluded that the distribution of the elements investigated in this study in free-living rats agrees with that in man, except for that of Ni. The above agreement gives proof of the possibility to use depot organs of rats for bioindication which was already mentioned in part I of this work.

    Municipal waste disposal facilities are typical semi-desirable facilities. Their location decision often needs to apply multi-objective decision methods and consider systemic cost and the undesirable effect. Unfortunately, the existing methods of measuring undesirable effect of trash disposal facilities ignore some obvious factors, such as wind directions, speed, etc. Therefore, they cannot exactly describe practical situations. Moreover, most current study focuses on two-layer municipal trash logistics network, which only covers trash generation points and final disposal points. However, the municipal trash disposal networks of most large and medium-sized cities are three-layer network, in which the transferring depots are one kind of essential facilities. This article first analyzes the characteristics of municipal trash transferring depots in order to understand the undesirable effect, such as local wind directions, wind speed and facility capacity, etc. The concept of "diffusion distances" is used to amend the traditional Euclidean distance and to state the real effect by considering all the above-mentioned factors. Subsequently, a piecewise function is proposed to measure the undesirable effect based on " diffusion distances". We further study the discrete three-level municipal trash logistics network with transferring depots. A multi-objective mixed integer programming model is introduced to optimize the trash transferring depots location problem in the network and minimize both of the annual total cost and the average daily undesirable effect. In order to solve the model, a two-stage hybrid simulated annealing algorithm (HSA) is devised according to problem features. Facilities location and the capacity of each facility are obtained in the first stage. The assignment of generation points among facilities selected in the previous stage is obtained in the second stage through a well-designed greedy algorithm. The multi-objective simulation of annealing

    We conducted an open-label, steady-state pharmacokinetic (PK) study of drug-drug interactions between depot medroxyprogesterone acetate (DMPA) and twice-daily lopinavir (LPV) plus low-dose ritonavir (RTV) (LPV/r) among 24 HIV-infected women and compared the results to those for HIV-infected women receiving DMPA while on no antiretroviral therapy or on nucleosides only (n = 14 subjects from the control arm of AIDS Clinical Trials Group [ACTG] study 5093). The objectives of the study were to address the effect of LPV/r on DMPA and to address the effect of DMPA on LPV/r therapy. PK parameters were estimated using noncompartmental analysis with between-group comparisons of medroxyprogesterone acetate (MPA) PKs and within-subject comparisons of LPV and RTV PKs before and 4 weeks after DMPA dosing. Plasma progesterone concentrations were measured every 2 weeks after DMPA dosing through week 12. Although the MPA area under the concentration-time curve and maximum concentration of drug in plasma were statistically significantly increased in the study women on LPV/r compared to those in the historical controls, these increases were not considered clinically significant. There were no changes in LPV or RTV exposure after DMPA. DMPA was well tolerated, and suppression of ovulation was maintained.

  20. Smart nanocontainers as depot media for feedback active coatings.

    2011-08-21

    Among the grand challenges at present are ways to develop systems with low consumption of raw materials and with little load on the environment. In view of this it is of utmost importance to avoid or to delay processes causing material destruction. This is especially urgent, since many protective substances have associated health hazards, and new routes to improve the situation are a main concern of this contribution. Nanocapsules (nanocontainers) with controlled release properties of the shell can be used to fabricate a new family of active coatings, with quick response to changes of the coating environment or coating integrity. The release of active materials encapsulated into nanocapsules is triggered by various external and internal factors, thus preventing spontaneous leakage of the active component. The coating can have several active functionalities when several types of nanocapsules loaded with corresponding active agent are incorporated simultaneously into a coating matrix. We highlight recent achievements in development and application of filled responsive containers in biomedical and self-healing protective coatings.

    Full Text Available Floristic composition in three industrial areas with soils contaminated by heavy metals (As, Cd, Cu, Hg, Pb, Zn and organic pollutants (polychlorinated biphenyls was studied. The content of Pb was only significantly correlated with the floristic composition and explained 13.8% of its variability considering spatial dependency of the sites. No correlation was found for PCBs. Altogether, 237 plant vascular species were found at three study sites (117, 133 and 105, respectively. The three study areas differed in their species composition represented by their own characteristic species. The gradient in the content of natives/non-natives, species number, prevailing life forms and indicator values for plant species investigated was revealed. Based on our results, for phytoremediation purposes we can select productive plant species with high biomass and ability to accumulate large amounts of heavy metals or organic compounds and surviving on soils with low mineral content.

Traditionally, injectable testosterone esters have been used for treatment, but they generate supranormal testosterone levels shortly after the 2- to 3-weekly injection interval and then testosterone levels decline very rapidly, becoming subnormal in the days before the next injection. The rapid fluctuations in plasma testosterone are subjectively experienced as disagreeable. Testosterone undecanoate is a new injectable testosterone preparation with a considerably better pharmacokinetic profile. After 2 initial injections with a 6-week interval, the following intervals between two injections are almost always 12-weeks, amounting eventually to a total of 4 injections per year. Plasma testosterone levels with this preparation are nearly always in the range of normal men, so are its metabolic products estradiol and dihydrotestosterone. The “roller coaster” effects of traditional parenteral testosterone injections are not apparent. It reverses the effects of hypogonadism on bone and muscle and metabolic parameters and on sexual functions. Its safety profile is excellent due to the continuous normalcy of plasma testosterone levels. No polycythemia has been observed, and no adverse effects on lipid profiles. Prostate safety parameters are well within reference limits. There was no impairment of uroflow. Testosterone undecanoate is a valuable contribution to the treatment options of androgen deficiency.Keywords: testosterone treatment, testosterone undecanoate, pharmacokinetic profile, clinical efficacy, side effects, sexual dysfunction

    This study focuses on the empty container management problem in a deficit regional area. Deficit area is the area having more export activities than the import activities, which always have a shortage of empty container. This environment has challenged the trading companies in the decision making in distributing the empty containers. A simulation model that fit to the environment is developed. Besides, a simple heuristic algorithm with some hard and soft constraints consideration are proposed to plan the logistic of empty container supply. Then, the feasible route with the minimum cost will be determined by applying the proposed heuristic algorithm. The heuristic algorithm can be divided into three main phases which are data sorting, data assigning and time window updating.

    Superparamagnetic magnetic nanoparticles were successfully functionalized with poly(methacrylic acid) via atom transfer radical polymerization, followed by conjugation to doxorubicin (Dox). Because of pH-sensitive hydrazone linkages, the rate and extent of Dox release from the particles was higher at a lower pH and/or a higher temperature than at physiological conditions. Appropriate changes to the pH and temperature can increase the drug release from the particles. Because of the released drug, the particles were found to be cytotoxic to human breast cancer cells in vitro. Such magnetic nanoparticles, with the potential to retain drug under physiological conditions and release the drug in conditions where the pH is lower or temperature is higher, may be useful in magnetic drug targeting by reducing the side effects of the drug caused to healthy tissues. In addition, they may serve as hyperthermia agents where the high temperatures used in hyperthermia can trigger further drug release.

    2015-01-01

    Full Text Available Centralized assigning of bus running between multiple lines can save operation cost of transit agency. As more big transit terminals can serve for multiple bus lines being established, coordinating the operation of these lines’ vehicles becomes more economical and perspective. This paper proposed a vehicle-scheduling model for multiple lines which share vehicle resource together and service based on the same terminal. The optimization goal is to minimize the number of vehicles while considering reducing the invalid operation time under the constraint of timetable schemes and matching time for vehicle crossing two lines. A case in Ningbo city, China, was conducted to compare the performance of the cross-line schedules with the original schedules assigning vehicles within respective lines. The optimized schedules can reduce 7.14% vehicles in need while meeting the timetable schemes of all bus lines, which indicated that the proposed model is suitable for operation practice.

    Diesel fuel is known to emit pollutants that have a negative impact on environmental and human health. In developing countries like South Africa, attendants are employed to pump fuel for customers at service stations. Attendants refuel vehicles with various octane unleaded fuel, lead-replacement petrol and diesel fuel, on a daily basis. Attendants are at risk to adverse health effects associated with the inhalation of volatile organic compounds released from these fuels. The pollutants released include benzene, toluene, ethylbenzene and xylenes (BTEX), which are significant due to their high level of toxicity. In this study, a risk assessment of BTEX was conducted at a diesel service station for public buses. Using Radiello passive samplers, it was found that benzene concentrations were above recommended international standards. Due to poor ventilation and high exposure duration, the average benzene concentration over the sampling campaign exceeded the US Environmental Protection Agency's chronic inhalation exposure reference concentration. Lifetime cancer risk estimation showed that on average there is a 3.78 × 10-4 cancer risk, corresponding to an average chronic daily intake of 1.38 × 10-3 mg/kg/day of benzene exposure. Additionally, there were incidences where individuals were at potential hazard risk of benzene and toluene that may pose non-carcinogenic effects to employees.

    Sustained-release formulations of analgesic drugs are promising alternatives to repeated drug injections. Here, we compared a sustained-release formulation of buprenorphine (SB, 2.2 mg/kg) with a standard protocol of three injections of buprenorphine (Temgesic, 0.1 mg/kg/8 h) in mice. Buprenorphine serum concentration and analgesic action (thermal sensitivity) were determined in healthy mice. Additionally, the pain relief properties of both protocols were assessed after laparotomy using physiological and ethological measures of pain and recovery. Serum concentrations and thermal sensitivity tests indicated duration of action of at least 4 h (but less than 8 h) with the Temgesic protocol, and 24-48 h with SB. Behavioural and clinical parameters indicated at least partial pain relief after surgery for both protocols. Observed side-effects of buprenorphine independent of the protocol were increased activity, disturbed circadian rhythm and several abnormal behaviours. A tendency for decreased food and water intake as well as body weight reduction was also seen. Body weight decreased significantly in animals that received three injections of Temgesic, regardless of whether surgery was performed or not (P = 0.015; P = 0.023), hinting at a stress response towards this repeated intervention. In conclusion, an application interval of 8 h (Temgesic) appears too long and might lead to repeated periods with insufficient analgesia in animals undergoing lasting and/or substantial pain after surgery. In comparison to the standard protocol, SB provided a long-lasting, assured analgesia without possible stressful repeated injections in a standard surgical model, with only limited and acceptable behavioural side-effects.

    Full Text Available Diesel fuel is known to emit pollutants that have a negative impact on environmental and human health. In developing countries like South Africa, attendants are employed to pump fuel for customers at service stations. Attendants refuel vehicles with various octane unleaded fuel, lead-replacement petrol and diesel fuel, on a daily basis. Attendants are at risk to adverse health effects associated with the inhalation of volatile organic compounds released from these fuels. The pollutants released include benzene, toluene, ethylbenzene and xylenes (BTEX, which are significant due to their high level of toxicity. In this study, a risk assessment of BTEX was conducted at a diesel service station for public buses. Using Radiello passive samplers, it was found that benzene concentrations were above recommended international standards. Due to poor ventilation and high exposure duration, the average benzene concentration over the sampling campaign exceeded the US Environmental Protection Agency’s chronic inhalation exposure reference concentration. Lifetime cancer risk estimation showed that on average there is a 3.78 × 10−4 cancer risk, corresponding to an average chronic daily intake of 1.38 × 10−3 mg/kg/day of benzene exposure. Additionally, there were incidences where individuals were at potential hazard risk of benzene and toluene that may pose non-carcinogenic effects to employees.

    The present study aimed to identify genes exhibiting concomitant obesity-dependent changes in DNA methylation and gene expression in adipose tissues in the mouse using diet-induced obese (DIO) C57BL/6J and genetically obese ob/ob mice as models. Mature adipocytes were isolated from epididymal and inguinal adipose tissues of ob/ob and DIO C57BL/6J mice. DNA methylation was analyzed by MeDIP-sequencing and gene expression by microarray analysis. The majority of differentially methylated regions (DMRs) were hypomethylated in obese mice. Global methylation of long interspersed elements indicated that hypomethylation did not reflect methyl donor deficiency. In both DIO and ob/ob mice, we observed more obesity-associated methylation changes in epididymal than in inguinal adipocytes. Assignment of DMRs to promoter, exon, intron and intergenic regions demonstrated that DIO-induced changes in DNA methylation in C57BL/6J mice occurred primarily in exons, whereas inguinal adipocytes of ob/ob mice exhibited a higher enrichment of DMRs in promoter regions than in other regions of the genome, suggesting an influence of leptin on DNA methylation in inguinal adipocytes. We observed altered methylation and expression of 9 genes in epididymal adipocytes, including the known obesity-associated genes, Ehd2 and Kctd15, and a novel candidate gene, Irf8, possibly involved in immune type 1/type2 balance. The use of 2 obesity models enabled us to dissociate changes associated with high fat feeding from those associated with obesity per se. This information will be of value in future studies on the mechanisms governing the development of obesity and changes in adipocyte function associated with obesity.

    Full Text Available John D CarmichaelDepartment of Medicine, Cedars-Sinai Medical Center, Los Angeles, CA, USAAbstract: Acromegaly is a rare disease characterized by excessive growth hormone secretion, usually from a pituitary tumor. Treatment options include surgery, medical therapy, and in some cases, radiation therapy. Current medical therapy consists of treatment with somatostatin analog medications or a growth hormone receptor antagonist. There are two somatostatin analogs currently in use, octreotide and lanreotide. Both are supplied in long-acting formulations and are of comparable biochemical efficacy. Lanreotide is supplied in a prefilled syringe and is injected into deep subcutaneous tissue. Studies have been conducted to assess the efficacy of self- or partner administration, and have demonstrated that injection of lanreotide can be accomplished reliably and safely outside a physician's office. For patients who have achieved biochemical control with lanreotide, the FDA has recently approved an extended dosing interval. Selected patients may be able to receive the medication less frequently with injections of 120 mg administered every 6 or 8 weeks. This review focuses on the use of lanreotide in the treatment of acromegaly, the safety and efficacy of the drug, and the benefits afforded to patients because of unique aspects of the delivery of lanreotide.Keywords: acromegaly, treatment, lanreotide, somatostatin analog, pituitary tumor

  20. PECVD de composes de silicium sur polymeres: Etude de la premiere phase du depot

    Science.gov (United States)

    Dennler, Gilles

    Since their first introduction in the early 90's, transparent barriers against oxygen and/or water vapor permeation through polymers, such as SiO 2, are the object of increasing interest in the food and pharmaceutical packaging industries, and more recently for the encapsulation of organic-based displays. It is now well known that these thin layers possess barrier properties only if they are thicker than a certain critical thickness, dc. For example, dc is around 12 nm in the case of SiO2 on KaptonRTM PI; below this value, the measured "Oxygen Transmission Rate" (OTR, in standard cm3/m2/day/bar) is roughly the same as that of the uncoated polymer. Until now, no detailed research has been carried out to explain this observation, but a hypothesis was proposed in the literature, based on island-like growth structure of the coating for d ≤ dc. According to this hypothesis, the surface energy of the polymeric substrates is so low that the Volmer-Weber (island-coalescence) growth mode occurs. We have aimed to verify this explanation, that is, to study the initial phase of silicon-compound (SiO2 and SiN) growth on four different polymeric substrates, namely polyimide (KaptonRTM PI), polycarbonate (LexanRTM PC), polypropylene (PP), and polyethyleneterephthalate (MylarRTM PET). Three different deposition methods were used, namely reactive evaporation of SiO, radio-frequency (RF) Plasma Enhanced Chemical Vapor Deposition (RF PECVD), and Distributed Electron Cyclotron Resonance (DECR) PECVD. In this latter case, the substrates were placed in three different positions: (i) in the active glow zone, (ii) downstream, and (iii) downstream, but shielded from photon emission (e.g. VUV) from the plasma. Angle-Resolved X-Ray Photoelectron Spectroscopy (ARXPS), Rutherford Backscattering Spectroscopy (RBS), and Scanning Electron Microscopy (SEM), the latter performed after Reactive Ion Etching (RIE) by oxygen plasma, revealed that growth indeed occurs in a Volmer-Weber mode in the case of evaporated films. The island coalescence was observed to occur at d = 1.2 nm, at which point the sticking coefficient of precursor species changes drastically. Finally, we have investigated the presence of an "interphase" between deposited coatings and the polymeric substrate. (Abstract shortened by UMI.)
