What Causes Cancer Gallbladder?: A Review

Gallbladder cancer is a common malignancy of the biliary tract. It is the fifth common malignancy of the gastrointestinal tract in United States [1] and third in Northern India [2]. Despite such high prevalence, there is scanty published literature about this disease in indexed journals. Therefore, this article is intended to provide a brief overview of gallbladder cancer risk factors, based mainly on published evidence from analytical epidemiology and recent research findings of biologists and practising oncologists. Furthermore, an attempt has been made to establish an association between different causative factors and the occurrence of the disease

On the Eccentricities and Merger Rates of Double Neutron Star Binaries and the Creation of "Double Supernovae"

We demonstrate that a natural consequence of an asymmetric kick imparted to neutron stars at birth is that the majority of double neutron star binaries should possess highly eccentric orbits. This leads to greatly accelerated orbital decay, due to the enormous increase in the emission of gravitational radiation at periastron as originally demonstrated by Peters (1964). A uniform distribution of kick velocities constrained to the orbital plane would result in ~24% of surviving binaries coalescing at least 10,000 times faster than an unperturbed circular system. Even if the planar kick constraint is lifted, ~6% of bound systems still coalesce this rapidly. In a non-negligible fraction of cases it may even be possible that the system could coalesce within 10 years of the final supernova, resulting in what we might term a "double supernova''. For systems resembling the progenitor of PSR J0737-3039A, this number is as high as \~9% (in the planar kick model). Whether the kick velocity distribution extends to the range required to achieve this is still unclear. We do know that the observed population of binary pulsars has a deficit of highly eccentric systems at small orbital periods. In contrast, the long-period systems favour large eccentricities, as expected. We argue that this is because the short-period highly eccentric systems have already coalesced and are thus selected against by pulsar surveys. This effect needs to be taken into account when using the scale-factor method to estimate the coalescence rate of double neutron star binaries. We therefore assert that the coalesence rate of such binaries is underestimated by a factor of several.Comment: 7 pages, 6 figures, submitted to Ap

Age related histological and histochemical studies on the testis of Aseel and Vanaraja breeds of poultry

Birds (10) of 2 age group, viz. 5 months (grower) and 13 months (adult) of Aseel and Vanaraja breeds of poultry were used. The thickness of tunica albuginea, maximum and minimum diameter of seminiferous tubules, diameter of primary spermatocytes and number of sustentacular cells or Sertoli cells per seminiferous tubule were significantly higher in growers and adults of Vanaraja than Aseel whereas, number of interstitial cells per field were significantly higher in growers and adults of Aseel than Vanaraja. The density of connective tissue fibers, PAS activity and AB-PAS activity was more in both groups of Vanaraja than Aseel

Identifying the most appropriate classifier for underpinning assistive technology adoption for people with dementia: an integration of Fuzzy AHP and VIKOR methods

Recently, the number of People with Dementia (PwD) has been rising exponentially across the world. The main symptoms that PwD experience include AQ1 impairments of reasoning, memory, and thought. Owing to the burden faced by this chronic condition, Assistive Technology-based solutions (ATS) have been prescribed as a form of treatment. Nevertheless, it is widely acknowledged that low adoption rates of ATS have hampered their benefits within a health and social care context. It is then necessary to effectively discriminate between adopters and non-adopters of such solutions to avoid cost implications, improve the life quality of adopters, and find intervention alternatives for non-adopters. Several classifiers have been proposed as advancement towards the personalisation of self-management interventions for dementia in a scalable way. As multiple algorithms have been developed, an important step in technology adoption is to select the most appropriate classification alternative based on different criteria. This paper presents the integration of Fuzzy AHP (FAHP) and VIKOR to address this challenge. First, FAHP was used to calculate the criteria and sub-criteria weights under uncertainty and then VIKOR was implemented to rank the classifiers. A case study considering a mobile-based self-management and reminding solution for PwD is described to validate the proposed approach. The results revealed that Easiness of interpretation (GW = 0.192) and Handling of missing data (GW = 0.145) were the two most important criteria. Furthermore, SVM (Qj = 1.0) and AB (Qj = 0.891) were concluded to be the most suitable classifiers for supporting ATS adoption in PwD
