Abstract: Satisfaction of patients is an important dimension of the hospital management and the evaluation of the quality of care and services offered to patients. Objective: To estimate the degree of satisfaction of patients admitted in Physical Medicine and Rehabilitation Department in the National Hospital and University Center (CNHU-HKM) in Cotonou. Method: Cross-sectional study with descriptive and analytical aim. It was led from June 15th to October 15th 2013, on 158 patients or guides of children or not communicating patients having ambulatory care in the Department of Physical Medicine and Rehabilitation and who agree to participate to the study. The level of global satisfaction of the subjects was estimated with a digital scale from 0 to 10. It was secondarily transformed into a discreet qualitative variable. Result: Rate of participation was 63.2%. Patients had deficiencies of rheumatilogical origine (41.1%), neurological (27.2%), traumatological (24.1%). Their pathologies were evolving since 1 month to 10 years. It was about their first attendance of the Rehabilitation Department of CNHU-HKM in 72.2%. Patients’ degree of satisfaction was good for the deadliness of expectation, reception (80%), cleanliness of the building, respect of patients’ intimacy. Global satisfaction of patients was good in 72%. It was influenced by the deadline of evolution of the pathologies. Discussion-Conclusion: The level of satisfaction of patients admitted in the Rehabilitation Department in CNHU-HKM was acceptable. However, they are parameters that remain to be improved.

BMC Research Notes , 2012, DOI: 10.1186/1756-0500-5-158
Abstract: The methanol extract displayed both antimicrobial activities with minimum inhibitory concentration (MIC) values ranging from 32 to 512 μg/ml and antioxidant property with an IC50 value of 52.48 μg/ml. Its partition enhanced the antimicrobial activity in EtOAc extract (MIC = 16-128 μg/ml) and reduced it in hexane extract (MIC = 256-1024 μg/ml). In addition, this process reduced the antioxidant activity in EtOAc and hexane extracts with IC50 values of 78.11 and 90.04 μg/ml respectively. Fractionation of EtOAc extract gave seven kaempferol rhamnosides, including; kaempferitrin (1), kaempferol 3-O-α-L-(2-acetyl)rhamnopyranoside-7-O-α-L-rhamnopyranoside (2), kaempferol 3-O-α-L-(3-acetyl)rhamnopyranoside-7-O-α-L-rhamnopyranoside (3), kaempferol 3-O-α-L-(4-acetyl)rhamnopyranoside-7-O-α-L-rhamnopyranoside (4), kaempferol 3-O-α-D- glucopyranoside-7-O-α-L-rhamnopyranoside (5), afzelin (6) and α-rhamnoisorobin (7). All these compounds, except 6 were isolated from this plant for the first time. Compound 7 was the most active, with MIC values ranging from 1 to 2 μg/ml and its antioxidant activity (IC50 = 0.71 μg/ml) was higher than that of the reference drug (IC50 = 0.96 μg/ml).These findings demonstrate that Bryophyllum pinnatum and some of its isolated compounds have interesting antimicrobial and antioxidant properties, and therefore confirming the traditional use of B. pinnatum in the treatment of infectious and free radical damages.Bryophyllum pinnatum (Lank.) Oken, syn. B. calucinum or Kalanchoe pinnata (Crassulaceae) is a perennial succulent herb which grows in Africa and Asia [1]. An ethnobotanical survey of plants used in the treatment of infectious diseases in Mbouda subdivision (Cameroon) indicated that B. pinnatum was one of the most used medicinal plants in the area. Therefore information collected directly from traditional healers and herbal sellers in this area indicated that, leaves or the whole plant are used as analgesic and to treat blennorrhoea, syphilis, jaun
A Tale of Two Motives: Endogenous Time Preference, Cash-in-Advance Constraints and Monetary Policy  [PDF]

Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.46045

This paper demonstrates the effects of modeling an endogenous rate of time preference and two cash-in-advance constraints. If the constraint is levied on consumption and capital goods, time preference effects are neutral and cash-in-advance constraint effects invert the Tobin Effect. If the constraint applies solely to consumption goods, opposing motives are offsetting and monetary policy is super neutral.

Targeting Phosphodiesterase 4 to Block the Link between Acute Exacerbation of Chronic Obstructive Pulmonary Disease and the Metabolic Complications  [PDF]
Eric Cho
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.311007
Abstract: The metabolic disorders such as obesity and diabetes are found to be more frequent in chronic obstructive pulmonary disease (COPD). The chronic systemic inflammation orchestrated by macrophages constitutes one critical pathophysiological process underlying both acute exacerbation of COPD (AECOPD) and its metabolic complications such as obesity and diabetes. The cyclic adenosine monophosphate (cAMP) signaling controlled by phosphodiesterase (PDE) 4 is a pivotal intracellular modulator for macrophages functions in immune inflammatory response underlying AECOPD as well as obesity and diabetes. Targeting PDE4/cAMP signaling has been suggested to be effective in treating AECOPD or the metabolic disorders of obesity and diabetes. It is therefore reasonable to hypothesize that the chronic systemic inflammation can be a critical link between AECOPD and the metabolic disorders and targeting the PDE4/cAMP signaling can be effective to block this link between AECOPD and the associated metabolic complications.
A Method to Calculate Inductance in Systems of Parallel Wires  [PDF]
Eric Deyo
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2017, DOI: 10.4236/jemaa.2017.91001
Abstract: This paper gives a method that maps the static magnetic field due to a system of parallel current-carrying wires to a complex function. Using this function simplifies the calculation of the magnetic field energy density and inductance per length in the wires, and we reproduce well-known results for this case.
Eradication of Staphylococcus aureus and MRSA in the Nares: A Historical Perspective of the Ecological Niche, with Suggestions for Future Therapy Considerations  [PDF]

Abstract: Nasal colonization with pathogenic bacteria continues to present challenges for patients undergoing surgical procedures, and for the physicians that treat them. Even as molecular medicine produces ever faster and improved data sets for clinicians, it would benefit all medical personnel attempting to decolonize the nose to better understand the historical nasal decolonization data with specific reference to the ecological niche for these bacteria, as it has been recorded for more than a century. Much of the historical data points to the largest ecological niche for nasal Staphylococcus aureus as the vibrissae of the vestibulum nasi. A careful study shows that any topical antimicrobial preparation needs to successfully penetrate the deepest recesses of these specialized nasal hair follicles, if decolonization is to be adequately accomplished. This review highlights the most relevant data of the last 140 years concerning the staphylococcal ecological niche of the vibrissae. Also to be discussed will be a historical review of topical Mupirocin. Almost thirty years after its FDA approval, Mupirocin is still the most widely used topical antibiotic for decolonization therapy around the world. Correspondingly, new experimental in vitro data will be presented showing the differing efficacy of Mupirocin against multiple strains of HA-MRSA and CA- MRSA, based solely on the commercial topical formulation (non Mupirocin ingredients) that acts synergistically with the Mupirocin. Finally, the review will discuss why an understanding of these historical data is a vital component to integrate into any new or augmented nasal decolonization therapy.
Origin of Little Missouri River - South Fork Grand River and nearby Drainage Divides in Harding County, South Dakota and Adjacent Eastern Montana, USA  [PDF]

Barbed tributaries flowing in southeast directions, an asymmetric drainage divide with both the South Fork Grand River and the North Fork Moreau River, and the Jump-off escarpment-surrounded basin (interpreted here to be a large abandoned headcut) are examples of topographic map evidence suggesting the north oriented Little Missouri River valley eroded headward across a large southeast oriented anastomosing complex of ice-marginal melt water flood flow channels that once crossed Harding County, South Dakota. Additional evidence includes southeast oriented tributaries to the northeast oriented South Fork Grand River and multiple divide crossings (e.g. through valleys and wind gaps) on the Boxelder Creek-Little Missouri River divide (in eastern Montana and west of the Little Missouri River) and suggests deep regional erosion occurred as the north oriented Little Missouri River valley eroded headward into and across the region. Harding County is located south and west of the southwest limit of coarse-grained glacial erratic material and ice-marginal melt water flow routes logically should have crossed it. Deep melt water erosion of Harding County and adjacent eastern Montana regions to the west is not consistent with many previous drainage history and glacial history interpretations, but is consistent with deep erosion by continental ice sheets.
Origin of Mountain Passes across Continental Divide Segments Surrounding the Southwest Montana Big Hole and Beaverhead River Drainage Basins, USA  [PDF]

Open Journal of Geology (OJG) , 2017, DOI: 10.4236/ojg.2017.79091
Abstract: The evolution of southwest Montana’s Big Hole and Beaverhead River drainage basins is determined from topographic map evidence related to mountain passes crossing what are today high altitude drainage divides including North America’s east-west Continental Divide. Map evidence, such as orientations of valleys leading away from mountain passes (and saddles) and barbed tributaries found along the downstream drainage routes, is used to reconstruct flow directions of streams and rivers that once crossed the present-day high mountain divides. Large south-oriented anastomosing complexes of diverging and converging channels are interpreted to have eroded what are today closely spaced passes and saddles now notched into high mountain ridges. Water in those south-oriented channels is interpreted to have flowed across emerging mountains and subsiding basins. Headward erosion of deeper southeast-oriented valleys, assisted by crustal warping, concentrated south-oriented water in fewer and deeper valleys as the water flowed from southwest Montana into what are today Idaho and the Snake River drainage basin. Headward erosion of the Big Hole River valley between the emerging Anaconda and Pioneer Mountains, also assisted by crustal warping, reversed all Big Hole Basin drainage so as to create the north-, east-, and south-oriented Big Hole River drainage route. A final and even more major reversal of flow in the present-day north-oriented Montana Missouri River valley, with the assistance of additional crustal warping, next ended all remaining flow to Idaho and the Snake River drainage basin and reversed and captured all drainage in the present-day north-oriented Big Hole, Beaverhead, and Red Rock River drainage basins. The observed map evidence indicates that prior to the final flow reversal events, large volumes of south-oriented water flowed across southwest Montana’s Big Hole and Beaverhead River drainage basins.
Analysis of Mountains Passes along the East-West Continental Divide and Other Drainage Divides Surrounding the Boulder River Drainage Basin, Jefferson County, Montana, USA  [PDF]

Open Journal of Geology (OJG) , 2017, DOI: 10.4236/ojg.2017.711108
Abstract: Detailed topographic maps of drainage divides surrounding the Jefferson County, Montana, Boulder River drainage basin were analyzed to determine the nature of drainage systems that preceded today’s Boulder River drainage system and how the Boulder River drainage system evolved from those earlier drainage systems. The Boulder River studied here drains in a north, east, and south direction to the Jefferson River, which at Three Forks, Montana joins the north-oriented Madison and Gallatin Rivers to form the north-oriented Missouri River. The North American east-west Continental Divide surrounds the Boulder River drainage basin western half and mountainous drainage divides with the Jefferson and Missouri Rivers surround the drainage basin’s eastern half. More than 25 deep mountain passes are notched into these drainage divides and provide evidence of the regional drainage system that preceded the present day Boulder River drainage system. Analysis of pass elevations and of orientations of valleys leading in opposite directions from those mountain passes shows that prior to Boulder River drainage system development immense volumes of south-oriented water moving in anastomosing complexes of diverging and converging channels flowed across the Boulder River drainage basin area and that the Boulder River drainage system evolved as deeper channels progressively captured flow from shallower channels. While not documented in detail crustal warping probably raised Boulder River drainage basin areas relative to adjacent valleys and basins as capture events took place. A water source was not determined, but may have been from a large North American continental ice sheet, although Boulder River drainage basin evolution probably occurred while mid Tertiary sediments were filling adjacent valleys and basins.
Topographic Map Analysis of Laramie Range Bedrock-Walled Canyon Complex and the Goshen Hole Escarpment-Surrounded Basin, Albany and Platte Counties, Southeast Wyoming, USA  [PDF]
Eric Clausen
Open Journal of Geology (OJG) , 2018, DOI: 10.4236/ojg.2018.81003
Abstract: The Laramie River after flowing in a north direction through southeast Wyoming’s Laramie Basin abruptly turns in an east direction to flow across the north-to-south oriented Laramie Range in a bedrock-walled canyon and eventually reaches the lower elevation Great Plains and southeast-oriented North Platte River. The North Laramie River, Bluegrass Creek, and North Sybille/Sybille Creek also flow from the Laramie Basin in separate bedrock-walled valleys into the Laramie Range before eventually joining the Laramie River. Bedrock-walled through valleys link the various Laramie Range stream and river crossing valleys and detailed topographic maps were used to determine how this anastomosing bedrock-walled canyon complex and the large escarpment-surrounded Goshen Hole basin (located just to the east of the anastomosing canyon complex) originated. Map evidence shows multiple streams of water must have diverged in the Laramie Basin from the north-oriented Laramie River to enter the Laramie Range before converging in or east of the Laramie Range and also shows how present day through valleys enabled diverging and converging streams of water to cross the Laramie Range. The anastomosing bedrock-walled valley complex studied here extends from north of the North Laramie River valley to south of the North Sybille/Sybille Creek valley. Large volumes of water flowing from the Laramie Basin to the Great Plains are interpreted to have eroded the anastomosing canyon complex and the “downstream” Goshen Hole escarpment-surrounded basin. Headward erosion of the north-oriented Sybille and Chugwater Creek valleys across large sheets of east-oriented water are interpreted to have left the Goshen Hole escarpment-surrounded basin as a large abandoned headcut. A water source was not determined, although a continental ice sheet that deeply eroded and warped the North American continent is considered to be a possible source.
