    Top height and dominant heights are 'Confusedlyinterpret in many countries. The mainaim of this study was find the similarity of above two terms and to build some models topredict them.The study was carried out in Yagirala 25 year old even aged Pinus caribaea plantation.Top height and dominant heights were compared with other tree variables. Stratifiedrandom sampling without replacement was used to select the sampling unit. Circular plotsof 0,05 hectare with slope correction and boundary adjustment were used to obtain therequired tree measurementsDiameter at breast height, total height, lower and upper crownheight were measured andbasal area and crown depth were calculated. Top height and dominant height were alsoestimated.Results indicated that there is a significant difference between top and dominant heights.Also two separate equations to predict these two heights were developed. According to theresults initially ten equations were selected. Five equations described the relationshipbetween top and total height while the other five described the relationship betweendominant height and total height. Finally the best two equations were selected usingcoefficient of variation values and the distributions of standard residuals.

    Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

    Moisture gradients, form a vapor cycle within the viscous boundary layer as an organizing principle to worker termites

    Studies of termite mound building have considered the mud they prepare, its properties and its composition. Here we consider the behaviors of the mound building termites Macrotermes michaelseni, (Sjostedt), in the presence of the viscous boundary layer (VBL), which spontaneously forms over any surface that air passes over. We looked how soil moisture and air vapor are coupled to form a feedback loop and a spatiotemporal precursor to worker termites in the presence of mound material. We explored residency and activities of workers when presented with a VBL and either varying substrate temperature gradients or a soil moisture transition within the soil substrate. We report the emergence of a ‘vapor conveyor’, which forms around a neutral evaporative equilibrium point (NEEP) at the soil/air interface, where the soil-borne moisture temperature (along the gradient) and the 100% saturated air-borne vapor temperature coincide within the VBL, forming a bubble of neutral mass transfer which, we propose, worker termites are sensitive to as viscosity changes within. We found, on average, that 67% (std. dev 27%) of behavioral events (clustering, excavation, and deposition) occurred within 10C either side of the NEEP. We found negative correlation (-0.78) between the substrate temperature gradient (0.1-0.9 0C mm-1) and the extents of behavioral activity, suggesting coupling between soil-borne moisture and air-borne vapor advection within the VBL. We recorded unique behaviors relating to interaction with the viscosity of vapor saturated air at this scale. We speculate that workers may exploit the VBL to overcome a classic trade-off, i.e. how to push activities forward into potentially desiccating environments, while conserving moisture in both the termites and the soil they build with

    JPN Guidelines for the management of acute pancreatitis: epidemiology, etiology, natural history, and outcome predictors in acute pancreatitis

    Acute pancreatitis is a common disease with an annual incidence of between 5 and 80 people per 100 000 of the population. The two major etiological factors responsible for acute pancreatitis are alcohol and cholelithiasis (gallstones). The proportion of patients with pancreatitis caused by alcohol or gallstones varies markedly in different countries and regions. The incidence of acute alcoholic pancreatitis is considered to be associated with high alcohol consumption. Although the incidence of alcoholic pancreatitis is much higher in men than in women, there is no difference in sexes in the risk involved after adjusting for alcohol intake. Other risk factors include endoscopic retrograde cholangiopancreatography, surgery, therapeutic drugs, HIV infection, hyperlipidemia, and biliary tract anomalies. Idiopathic acute pancreatitis is defined as acute pancreatitis in which the etiological factor cannot be specified. However, several studies have suggested that this entity includes cases caused by other specific disorders such as microlithiasis. Acute pancreatitis is a potentially fatal disease with an overall mortality of 2.1%–7.8%. The outcome of acute pancreatitis is determined by two factors that reflect the severity of the illness: organ failure and pancreatic necrosis. About half of the deaths in patients with acute pancreatitis occur within the first 1–2 weeks and are mainly attributable to multiple organ dysfunction syndrome (MODS). Depending on patient selection, necrotizing pancreatitis develops in approximately 10%–20% of patients and the mortality is high, ranging from 14% to 25% of these patients. Infected pancreatic necrosis develops in 30%–40% of patients with necrotizing pancreatitis and the incidence of MODS in such patients is high. The recurrence rate of acute pancreatitis is relatively high: almost half the patients with acute alcoholic pancreatitis experience a recurrence. When the gallstones are not treated, the risk of recurrence in gallstone pancreatitis ranges from 32% to 61%. After recovering from acute pancreatitis, about one-third to one-half of acute pancreatitis patients develop functional disorders, such as diabetes mellitus and fatty stool; the incidence of chronic pancreatitis after acute pancreatitis ranges from 3% to 13%. Nevertheless, many reports have shown that most patients who recover from acute pancreatitis regain good general health and return to their usual daily routine. Some authors have emphasized that endocrine function disorders are a common complication after severe acute pancreatitis has been treated by pancreatic resection

    Endoscopic Drainage of Empyema of the Gallbladder Through A Concurrent Cholecystoduodenal Fistula

    Get PDF
    The duodenum is the most common site of cholecystoenteric fistulation resulting from cholecystitis or empyema of the gallbladder. This rare condition is usually only diagnosed intraoperatively and managed incidentally. This paper presents the endoscopic diagnosis of a case of cholecystoduodenal fistula arising from the late presentation of empyema of the gallbladder and its subsequent drainage through the fistula. As far as we can determine, this is the only reported case of opportunistic drainage of an empyema of the gallbladder through a concurrent cholecystoduodenal fistula

    Cytotoxic T - Lymphocyte Antigen-4&nbsp;(CTLA-4) gene located on 2q33 in human which plays an important role in the down regulation of CD28 interaction with the ligands on the surface of antigen-presenting cells (APCs). CTLA4 molecule is a susceptible gene for the severity of Graves’ disease (GD). Recent research studies showed that the association between the CTLA4 exon-1 49A/G single nucleotide polymorphism (SNP) and the developing Graves’ disease. So, the present study is planned to perform the meta-analysis to explore the association between the SNP49 and GD susceptibility in human beings to the society. SNP public databases and SNP databases showed that the genetic association of diseases such as obesity, diabetes, osteoporosis, asthma, hypertension, renal failure, heart diseases and thyroidism etc
