Neurocysticercosis: clinical presentations, serology and radiological findings: experience in a teaching institution
Background: The objective of the study was to study the clinical presentations, serological evidence and radiological findings in cases of neurocysticercosis in a teaching institution with attached tertiary care hospital settings.Methods: A total of 60 paediatric age group patients were enrolled in the study and their clinical presentations, serological profile and radiological findings were recorded. Study data was evaluated in a retrospective analysis of the descriptive hospital based observational study conducted at Safdarjang hospital (SJ) hospital, New Delhi.Results: Generalised seizures were the most predominant clinical presentation in 28/60 cases (47%). Majority of the patients had single lesions in parietal lobe in CT head. 90% of the patients showed perilesional oedema on CT scan. Differences in IgG positivity rate in the various age groups were not significant either for serum or CSF - the p values were 0.67 & 0.052 respectively. Seropositivity was also not significantly associated with presence of active NCC lesions on CT (p= 0.254). In further analysis, diet was not found to have any significant influence on either seropositivity (p value=0.673) or on the pattern of presentation on CT (p=0.260). NBM-It is disappointing to know that only 20% urban 45%rural is aware of 8 hours NBM before surgery.Conclusions: Observations suggest there is variability in the clinical, serological and radiological presentation of neurocysticercosis when compared with standard criteria.
Online Behaviour of Social Media Participantsâ and Perception of Trust, Comparing Social Media Brand Community Groups and Associated Organized Marketing Strategies
AbstractThe purpose of this study was to assess social media participantsâ perception of similarities and differences of the authenticity and trustworthiness of online advertising versus the authenticity and trustworthiness of respective online brand communities. We were looking at brand communities associated with Social Media that were formed on the basis of specific products or services. We further aimed to assess the trust individual participants in those brand communities obtain in contrast to information provided by companies and their marketing and public relations strategies. Our research then went beyond this comparative discussion in order to assess differences and similarities among individuals across different cultures. We believe that the connection between consumers may be stronger and perceived as equally or more trustworthy than the âtraditionalâ connection between an individual consumer and the information portrayed in marketing or public relations strategies by the company itself. We further believe that cultural differences in perceptions of trust may be minimal or non-existent
Non-occlusive mesenteric ischemia leading to 'pneumatosis intestinalis': a series of unfortunate hemodynamic events
Kif14 overexpression accelerates murine retinoblastoma development
The mitotic kinesin KIF14 has an essential role in the recruitment of proteins required for the final stages of cytokinesis. Genomic gain and/or overexpression of KIF14 has been documented in retinoblastoma and a number of other cancers, such as breast, lung and ovarian carcinomas, strongly suggesting its role as an oncogene. Despite evidence of oncogenic properties in vitro and in xenografts, Kif14's role in tumor progression has not previously been studied in a transgenic cancer model. Using a novel Kif14 overexpressing, simian virus 40 large T-antigen retinoblastoma (TAg-RB) double transgenic mouse model, we aimed to determine Kif14's role in promoting retinal tumor formation. Tumor initiation and development in double transgenics and control TAg-RB littermates were documented in vivo over a time course by optical coherence tomography, with subsequent ex vivo quantification of tumor burden. Kif14 overexpression led to an accelerated initiation of tumor formation in the TAg-RB model and a significantly decreased tumor doubling time (1.8 vs. 2.9 weeks). Moreover, overall percentage tumor burden was also increased by Kif14 overexpression. These data provide the first evidence that Kif14 can promote tumor formation in susceptible cells in vivo
Inpatient and Outpatient Infection as a Trigger of Cardiovascular Disease: The ARIC Study
Background
Acute infections are known cardiovascular disease (CVD) triggers, but little is known regarding how CVD risk varies following inpatient versus outpatient infections. We hypothesized that inâ and outpatient infections are associated with CVD risk and that the association is stronger for inpatient infections. Methods and Results
Coronary heart disease (CHD) and ischemic stroke cases were identified and adjudicated in the ARIC (Atherosclerosis Risk in Communities Study). Hospital discharge diagnosis codes and Medicare claims data were used to identify infections diagnosed in inâ and outpatient settings. A caseâcrossover design and conditional logistic regression were used to compare inâ and outpatient infections among CHD and ischemic stroke cases (14, 30, 42, and 90 days before the event) with corresponding control periods 1 and 2 years previously. A total of 1312 incident CHD cases and 727 incident stroke cases were analyzed. Inpatient infections (14âday odds ratio [OR]=12.83 [5.74, 28.68], 30âday OR=8.39 [4.92, 14.31], 42âday OR=6.24 [4.02, 9.67], and 90âday OR=4.48 [3.18, 6.33]) and outpatient infections (14âday OR=3.29 [2.50, 4.32], 30âday OR=2.69 [2.14, 3.37], 42âday OR=2.45 [1.97, 3.05], and 90âday OR=1.99 [1.64, 2.42]) were more common in all CHD case periods compared with control periods and inpatient infection was a stronger CHD trigger for all time periods (P Conclusions
Inâ and outpatient infections are associated with CVD risk. Patients with an inpatient infection may be at particularly elevated CVD risk and should be considered potential candidates for CVD prophylaxis
Effect of the thickness on the photocatalytic and the photocurrent properties of ZnO films deposited by spray pyrolysis
In this work, we have investigated the structure, morphology, photoluminescence, photocatalytic and photocurrent properties of ZnO thin films as a function of their film thickness (tZnO) fabricated via ultrasonic spray pyrolysis technique. The X-Ray diffraction patterns exhibited the formation of polycrystalline wurtzite phase of ZnO. Scanning electron microscopy images showed the uniform morphology with nanorod structure. The photosensitivity and photocatalytic efficiency are found to be optimum at tZnOâ=â1200 nm and are attributed to the improved photogeneration of charge carriers and higher concentration of oxygen vacancies. A direct correlation is established between the photosensitivity and photodegradation process. The incident photon-to-electron conversion efficiency (IPCE) and photocatalytic efficiency for the ZnO film at tZnOâ=â1200 nm are estimated to be 31.5% and 100% respectively. The obtained result suggests that ZnO thin films are potential candidates for applications in various optoelectronic devices.This study has been partially supported by Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Funding UIDB/FIS/04650/2020 (JPBS) and DST SERB Project ECR/2017/002537(K.K.).

Hospitalized Infection as a Trigger for Acute Ischemic Stroke
Acute triggers for ischemic stroke, which may include infection, are understudied, as is whether background cardiovascular disease (CVD) risk modifies such triggering. We hypothesized that infection increases acute stroke risk, especially among those with low CVD risk
Design, synthesis and biological evaluation of photoaffinity probes of antiangiogenic homoisoflavonoids
A naturally occurring homoisoflavonoid, cremastranone (1) inhibited angiogenesis in vitro and in vivo. We developed an analogue SH-11037 (2) which is more potent than cremastranone in human retinal microvascular endothelial cells (HRECs) and blocks neovascularization in animal models. Despite their efficacy, the mechanism of these compounds is not yet fully known. In the course of building on a strong foundation of SAR and creating a novel chemical tool for target identification of homoisoflavonoid-binding proteins, various types of photoaffinity probes were designed and synthesized in which benzophenone and biotin were attached to homoisoflavanonoids using PEG linkers on either the C-3âČ or C-7 position. Notably, the photoaffinity probes linking on the phenol group of the C-3âČ position retain excellent activity of inhibiting retinal endothelial cell proliferation with up to 72 nM of GI50
