Functional outcome after stroke in patients with aphasia and neglect: assessment by the motor and cognitive functional independence measure instrument.

BACKGROUND
The role of neuropsychological deficits in predicting functional outcome in patients with aphasia and neglect at the end of rehabilitation after stroke has been poorly investigated. This was the aim of this prospective study evaluated using a Functional Independence Measure (FIM) instrument.


METHODS
Patients with a primary diagnosis of cerebrovascular accident [125 patients with aphasia, 45 with neglect and 131 without either aphasia or neglect (WAN)] were enrolled. Backward multiple linear regression analysis was used to predict motor and cognitive FIM, discharge destination, and length of stay. The independent variables were age, gender, aphasia, stroke type, stroke lesion size, comorbidity, bladder catheter, stroke severity, trunk control test, initial motor FIM, and committed caregiver identified on admission to rehabilitation.


RESULTS
At the end of rehabilitation, patients with neglect had significantly lower final motor FIM scores and lower daily efficiency improvement in motor FIM scores compared with those with aphasia (both p < 0.001) and WAN (both p < 0.001). Patients with aphasia showed lower final cognitive FIM scores compared with those with neglect (p < 0.001) and those without deficits (p < 0.001). Neglect was a predictor of final motor FIM (β = -0.24) and efficiency in motor FIM (β = -0.29), while aphasia was a predictor of final cognitive FIM (β = -0.54). Neglect and aphasia did not differ and were not predictors of discharge destination and length of stay.


CONCLUSIONS
Patients with neglect have lower motor FIM scores if compared with those with aphasia, while patients with aphasia have lower cognitive FIM scores. Neglect is a predictor of motor FIM, while aphasia is a predictor of cognitive FIM scores.
Effects of 4-week self cross body stretching with scapular stabilization on shoulder motions and horizontal adductor strength in subjects with limited shoulder horizontal adduction.

BACKGROUND
Posterior shoulder tightness (PST) is related to shoulder conditions such as shoulder impingement and limited shoulder horizontal adduction (SHA). The purpose of this study was to compare the effects of self cross body stretching (CBS) with and without scapular stabilization (SS) on SHA and shoulder internal rotation (SIR) range of motion (ROM) and shoulder horizontal adductor strength (SHAS) in subjects with limited SHA.


METHODS
Twenty-six subjects (14 males, 12 females) with limited SHA was participated in this study. The SS group and without stabilization (WS) group were assigned randomly. The SS group performed self CBS with SS by applying belt just under the subject's axilla. The subjects were asked to perform self CBS in 4 times a week for 4 weeks. SHA and SIR RM were measured by Clinometer smartphone application, and SHAS by hand-held dynamometer (HHD) before and after 4-week self CBS.


RESULTS
2 × 2 mixed analysis of variance (ANOVA) was used to identify the significance. If there was an interaction effect, t-test was used to confirm the simple effect. There was a significant interaction in SHA ROM and SHAS. The post-test value of SHA ROM was significantly greater in SS group than WS group (p < 0.0125). In SHAS, there was no significant difference between groups (p > 0.0125).


CONCLUSION
SS during self CBS could enhance to improve SHA, SIR ROM, and SHAS in individuals with limited SHA.
Penis and Prepuce

The penis is the male organ of copulation and is composed of erectile tissue that encases the extrapelvic portion of the urethra (Fig. 66-1). The penis of the horse is musculocavernous and can be divided into three parts: the root, the body or shaft, and the glans penis. The penis originates caudally at the root, which is fixed to the lateral aspects of the ischial arch by two crura (leg-like parts) that converge to form the shaft of the penis. The shaft constitutes the major portion of the penis and begins at the junction of the crura. It is attached caudally to the symphysis ischii of the pelvis by two short suspensory ligaments that merge with the origin of the gracilis muscles (Fig. 66-2). The glans penis is the conical enlargement that caps the shaft. The urethra passes over the ischial arch between the crura and curves cranioventrally to become incorporated within erectile tissue of the penis. The mobile shaft and glans penis extend cranioventrally to the umbilical region of the abdominal wall. The body is cylindrical but compressed laterally. When quiescent, the penis is soft, compressible, and about 50 cm long. Fifteen to 20 cm lie free in the prepuce. When maximally erect, the penis is up to three times longer than when it is in a quiescent state. Erectile Bodies
Reassessment of the Diagnostic Value of Histology in Patients with GERD, Using Multiple Biopsy Sites and an Appropriate Control Group

BACKGROUND:Histology is generally considered as a tool of limited value in the diagnosis of gastro-esophageal reflux disease (GERD).AIM:To reevaluate the diagnostic role of histological alterations in GERD, using multiple biopsy sites and an appropriate control group.METHODS:We studied 135 patients with typical and atypical symptoms of GERD. They underwent upper GI endoscopy and Los Angeles classification was used for grading cases with mucosal breaks. Biopsies were taken at the Z-line, 2 and 4 cm above it. Microscopic esophagitis was identified by necrosis/erosion, neutrophil/eosinophil intraepithelial infiltration, basal cell hyperplasia, elongation of papillae, dilation of intercellular spaces and a score (range: 0–2) was given for each lesion. Twenty-four-hour esophageal pH monitoring was performed in each patient. Twenty subjects without reflux symptoms, and with normal endoscopy and pH testing were considered as controls.RESULTS:Histological alterations were found in 100 of 119 GERD patients (84%) and in 3 of 20 controls (15%) with a significant difference (p < 0.00001). Histology was abnormal in 96% of patients with erosive esophagitis and in 76% of patients with nonerosive reflux disease (NERD). The sum of scores of microscopic lesions found in all biopsy sites ranged from 0 to 22 and we identified a cut-off value (score 2) that distinguished efficiently controls from GERD patients.CONCLUSIONS:In contrast with previous reports on the marginal role of histology in patients with GERD, our study shows that this technique can be a useful diagnostic tool, particularly in patients with NERD, when biopsies are taken at two sites including Z-line and 2 cm above it.
Orbital-specific mapping of the ligand exchange dynamics of Fe(CO)5 in solution

Transition-metal complexes have long attracted interest for fundamental chemical reactivity studies and possible use in solar energy conversion. Electronic excitation, ligand loss from the metal centre, or a combination of both, creates changes in charge and spin density at the metal site that need to be controlled to optimize complexes for photocatalytic hydrogen production and selective carbon–hydrogen bond activation. An understanding at the molecular level of how transition-metal complexes catalyse reactions, and in particular of the role of the short-lived and reactive intermediate states involved, will be critical for such optimization. However, suitable methods for detailed characterization of electronic excited states have been lacking. Here we show, with the use of X-ray laser-based femtosecond-resolution spectroscopy and advanced quantum chemical theory to probe the reaction dynamics of the benchmark transition-metal complex Fe(CO)5 in solution, that the photo-induced removal of CO generates the 16-electron Fe(CO)4 species, a homogeneous catalyst with an electron deficiency at the Fe centre, in a hitherto unreported excited singlet state that either converts to the triplet ground state or combines with a CO or solvent molecule to regenerate a penta-coordinated Fe species on a sub-picosecond timescale. This finding, which resolves the debate about the relative importance of different spin channels in the photochemistry of Fe(CO)5 (refs 4, 16,17,18,19 and 20), was made possible by the ability of femtosecond X-ray spectroscopy to probe frontier-orbital interactions with atom specificity. We expect the method to be broadly applicable in the chemical sciences, and to complement approaches that probe structural dynamics in ultrafast processes.
A subjective model for trustworthiness evaluation in the social Internet of Things

The integration of social networking concepts into the Internet of Things (IoT) has led to the so called Social Internet of Things (SIoT) paradigm, according to which the objects are capable of establishing social relationships in an autonomous way with respect to their owners. The benefits are those of improving scalability in information/service discovery when the SIoT is made of huge numbers of heterogeneous nodes, similarly to what happens with social networks among humans. In this paper we focus on the problem of understanding how the information provided by the other members of the SIoT has to be processed so as to build a reliable system on the basis of the behavior of the objects. We define a subjective model for the management of trustworthiness which builds upon the solutions proposed for P2P networks. Each node computes the trustworthiness of its friends on the basis of its own experience and on the opinion of the common friends with the potential service providers. We employ a feedback system and we combine the credibility and centrality of the nodes to evaluate the trust level. Preliminary simulations show the benefits of the proposed model towards the isolation of almost any malicious node in the network.
Hemodynamic determinants of oxygen consumption of the heart with special reference to the tension-time index.

SARNOFF, S. J., E. BRAUNWALD, G. H. WELCH, JR., R. B. CASE, W. N. STAINSBY AND R. MACRUZ. Hemodynamic determinants of oxygen cons~mnption of the heart with special reference to tension-time index. Am. J. Physiol. 192(1) : 148-156. 1958. -The hemodynamic determinants of myocardial oxygen utilization were aster tained in the isolated, metabolically supported, nonfailing canine heart. The primary determinant was found to be the total tension developed by the myocardium as indicated by the area beneath the systolic pressure curve (Tension-Time Index). The significance of these findings for the understanding of the low efficiency of the failing heart and the consequently increased importance of Laplace’s law are discussed. T HE PURPOSE of this investigation was to acquire a detailed and precise appreciation of the influence of each of the various hemodynamic phenomena, including the tension-time index, on the nonfailing heart’s utilization of oxygen. This required a preparation permitting a) independent control of these phenomena, b) essentially stable and nonfailing performance characteristics of the heart, and c) the ability to make determinations of total myocardial oxygen consumption with a high degree of precision. This experimental study was made possible by the isolated, metabolically supported, dog heart preparation ( I).
Effect of motor imagery training on symmetrical use of knee extensors during sit-to-stand and stand-to-sit tasks in post-stroke hemiparesis.

OBJECTIVE
To investigate the effect of motor imagery training (MIT) on the symmetrical use of knee extensors during sit-to-stand and stand-to-sit tasks.


METHODS
We measured the electromyographic (EMG) data in the knee extensor on the affected side of 3 volunteers with post-stroke hemiparesis. We used a single-subject multiple-baseline research design across individuals. The EMG data were collected from knee extensors while performing the sit-to-stand and stand-to-sit tasks. The EMG activation and onset time ratios for the knee extensors were calculated by dividing the EMG activation and onset time of knee extensor action on the affected side by these on the unaffected side. MIT consisted of a 10-min detailed description of 5 stages: preparation, sit-to-stand tasks, weight shifting during standing, stand-to-sit tasks, and completion.


RESULTS
During MIT, the EMG activation ratios of participants 1, 2, and 3 increased by 11.24%, 18.07%, and 26.91%, respectively, in the sit-to-stand task and by 12.11%, 14.31%, and 25.92%, respectively, in the stand-to-sit task. During MIT, the onset time of participants 1, 2, and 3 decreased by 36.09%, 24.27%, and 25.61%, respectively, in the sit-to-stand task and by 26.81%, 27.20%, and 22.83%, respectively, for the stand-to-sit task.


CONCLUSION
These findings suggest that MIT has a positive effect on the symmetrical use of knee extensors during sit-to-stand and stand-to-sit tasks.
Starch-composition, fine structure and architecture

Much has been written over many decades about the structure and properties of starch. As technology develops, the capacity to understand in more depth the structure of starch granules and how this complex organisation controls functionality develops in parallel. This review puts the current state of knowledge about starch structure in perspective and integrates aspects of starch composition, interactions, architecture and functionality. q 2003 Elsevier Ltd.

The simple economics of cybercrimes

The characteristics of cybercriminals, cybercrime victims, and law enforcement agencies have a reinforcing effect on each other, leading to a vicious circle of cybercrime. In this article, the author assessed the cost-benefit structure of cybercriminals. From the potential victims' perspectives, an economic analysis can help explain the optimum investment necessary as well as the measures required to prevent hackers from cracking into their computer networks. The analysis from the cybercriminal's viewpoint also provides insight into factors that might encourage and energize his or her behavior.
Care of the Athlete With Type 1 Diabetes Mellitus: A Clinical Review

CONTEXT
Type 1 diabetes mellitus (T1DM) results from a highly specific immune-mediated destruction of pancreatic β cells, resulting in chronic hyperglycemia. For many years, one of the mainstays of therapy for patients with T1DM has been exercise balanced with appropriate medications and medical nutrition. Compared to healthy peers, athletes with T1DM experience nearly all the same health-related benefits from exercise. Despite these benefits, effective management of the T1DM athlete is a constant challenge due to various concerns such as the increased risk of hypoglycemia. This review seeks to summarize the available literature and aid clinicians in clinical decision-making for this patient population.


EVIDENCE ACQUISITION
PubMed searches were conducted for "type 1 diabetes mellitus AND athlete" along with "type 1 diabetes mellitus AND exercise" from database inception through November 2015. All articles identified by this search were reviewed if the article text was available in English and related to management of athletes with type 1 diabetes mellitus. Subsequent reference searches of retrieved articles yielded additional literature included in this review.


RESULTS
The majority of current literature available exists as recommendations, review articles, or proposed societal guidelines, with less prospective or higher-order treatment studies available. The available literature is presented objectively with an attempt to describe clinically relevant trends and findings in the management of athletes living with T1DM.


CONCLUSIONS
Managing T1DM in the context of exercise or athletic competition is a challenging but important skill for athletes living with this disease. A proper understanding of the hormonal milieu during exercise, special nutritional needs, glycemic control, necessary insulin dosing adjustments, and prevention/management strategies for exercise-related complications can lead to successful care plans for these patients. Individualized management strategies should be created with close cooperation between the T1DM athlete and their healthcare team (including a physician and dietitian).
The Global Burden of Snakebite: A Literature Analysis and Modelling Based on Regional Estimates of Envenoming and Deaths

BACKGROUND
Envenoming resulting from snakebites is an important public health problem in many tropical and subtropical countries. Few attempts have been made to quantify the burden, and recent estimates all suffer from the lack of an objective and reproducible methodology. In an attempt to provide an accurate, up-to-date estimate of the scale of the global problem, we developed a new method to estimate the disease burden due to snakebites.


METHODS AND FINDINGS
The global estimates were based on regional estimates that were, in turn, derived from data available for countries within a defined region. Three main strategies were used to obtain primary data: electronic searching for publications on snakebite, extraction of relevant country-specific mortality data from databases maintained by United Nations organizations, and identification of grey literature by discussion with key informants. Countries were grouped into 21 distinct geographic regions that are as epidemiologically homogenous as possible, in line with the Global Burden of Disease 2005 study (Global Burden Project of the World Bank). Incidence rates for envenoming were extracted from publications and used to estimate the number of envenomings for individual countries; if no data were available for a particular country, the lowest incidence rate within a neighbouring country was used. Where death registration data were reliable, reported deaths from snakebite were used; in other countries, deaths were estimated on the basis of observed mortality rates and the at-risk population. We estimate that, globally, at least 421,000 envenomings and 20,000 deaths occur each year due to snakebite. These figures may be as high as 1,841,000 envenomings and 94,000 deaths. Based on the fact that envenoming occurs in about one in every four snakebites, between 1.2 million and 5.5 million snakebites could occur annually.


CONCLUSIONS
Snakebites cause considerable morbidity and mortality worldwide. The highest burden exists in South Asia, Southeast Asia, and sub-Saharan Africa.

HOXA-10 expression in the mid-secretory endometrium of infertile patients with either endometriosis, uterine fibromas or unexplained infertility.

BACKGROUND
The aim of this study was to investigate HOXA-10 expression in endometrium from infertile patients with different forms of endometriosis; with uterine fibromas, or with unexplained infertility and from normal fertile women.


METHODS
Expression levels of HOXA-10 mRNA and protein in endometrium were measured during the mid-secretory phase. This study utilized laser capture microdissection, real-time RT-PCR and immunohistochemistry.


RESULTS
HOXA-10 mRNA and protein expression levels in endometrial stromal cells were significantly lower in infertile patients with different types of endometriosis (deep infiltrating endometriosis, ovarian endometriosis and superficial peritoneal endometriosis), with uterine myoma, and unexplained infertility patients as compared with healthy fertile controls. HOXA-10 mRNA expression levels of microdissected glandular epithelial cells were significantly lower than those of microdissected stromal cells, without significant differences among the different groups. No protein expression was detected in glandular epithelial cells. The percentage of patients with altered protein expression of HOXA-10 in stromal cells were significantly higher in patients with only superficial peritoneal endometriosis (100%, 20/20, P < 0.05) compared with the other infertile groups (deep infiltrating endometriosis: 72.7%, 16/22; ovarian endometriosis: 70.0%, 14/20; uterine myoma: 68.8%, 11/16; unexplained infertility: 55.6%, 5/9).


CONCLUSION
The present findings suggested that altered expression of HOXA-10 in endometrial stromal cells during the window of implantation may be one of the potential molecular mechanisms of infertility in infertile patients, particularly in patients with only superficial peritoneal endometriosis. One of the underlying causes of infertility in patients with only superficial endometriosis may be altered expression of HOXA-10 in endometrial stromal cells.
Agile Load Transportation : Safe and Efficient Load Manipulation with Aerial Robots

In the past few decades, unmanned aerial vehicles (UAVs) have become promising mobile platforms capable of navigating semiautonomously or autonomously in uncertain environments. The level of autonomy and the flexible technology of these flying robots have rapidly evolved, making it possible to coordinate teams of UAVs in a wide spectrum of tasks. These applications include search and rescue missions; disaster relief operations, such as forest fires [1]; and environmental monitoring and surveillance. In some of these tasks, UAVs work in coordination with other robots, as in robot-assisted inspection at sea [2]. Recently, radio-controlled UAVs carrying radiation sensors and video cameras were used to monitor, diagnose, and evaluate the situation at Japans Fukushima Daiichi nuclear plant facility [3].
Effects of heavy-resistance triceps surae muscle training on strength and muscularity of men and women.

The purpose of this study was to determine selected functional and structural effects of heavy-resistance training on the triceps surae muscles of men and women. We pretested 28 men and 28 women for triceps surae muscle isotonic strength and muscularity after five practice sessions that familiarized them with the study equipment. Triceps surae muscle isotonic strength was determined using a 1-repetition maximum seated heel raise. Muscularity involved the measurement of relaxed lower leg circumference and net circumference and ultrasonically determined triceps surae muscle thickness. Twenty-eight subjects (14 men, 14 women) were selected randomly after pretesting to participate in 24 sessions of standardized weight training primarily involving the triceps surae muscles, and the remaining subjects (14 men, 14 women) served as nontraining controls. After eight weeks of training, triceps surae muscle isotonic strength had increased significantly (p less than .001) for both men and women in the Treatment Group when compared with the Control Group. No other dependent variables changed significantly. We concluded that eight weeks of heavy-resistance training involving the triceps surae muscles elicits similar significant increases in isotonic muscle strength in both men and women without concurrent increases in muscularity.
