Ibrutinib exerts potent antifibrotic and antitumor activities in mouse models of pancreatic adenocarcinoma. The combination of monthly carboplatin and weekly paclitaxel is highly active for the treatment of recurrent ovarian cancer. Response of renal cell carcinoma to ibrutinib, a bruton tyrosine kinase inhibitor, in a patient treated for chronic lymphocytic leukemia. Deploying ibrutinib to lung cancer: Another step in the quest towards drug repurposing. The cancer cell line encyclopedia enables predictive modelling of anticancer drug sensitivity. The protein can also be staine~ with a number of dyes like bromphenol blue, azocarmine, amidoblack or light gr~en S. For routine use, bromphenol blue is the most suitable, ~he analysis ~f the be done by two ways-elutiOn and scanning. The denslt~es of these eluates are measured in a colorimeter or a spectrophotometer using a suitable wavelength. From the density values thus obtained, the relative percentages of different concentration estimated. This procedure assumes that all proteins with the stain, that dye uptake is directly proportional to the protein concentration and that dye binding capacity of various fractions bears a simple relationship to each other at all concentrations. In this method the only disadvantage is that the electrophoretogram is distroyed and duplicate run is necessary when a record is required. In scanning, a suitable scanner measures the optical density of the protein dye complex. Previously, clarification of the filter paper electrophoretogram by liquid paraffin or a mineral oil was necessary. However, this difficulty has been overcome by photoelectric devices which measure the light reflected from the dry paper. Filter paper electrophoresis is used not only for the separation of serum proteins but also it can be utilized for the quantitative evaluations of carbohydrates, lipids, cholesterol, amino acids, several antigen- antibody mixtures, and mixtures of several other components, the separation of which may not be possible by other routine methods. This method thus remains a method of choice because of its advantages such as low cost, speed of analysis, ease of running multiple samples, the small volume of the serum analysis and the facility of differentiating types of proteins. The first band which is very thick but narrow is due to albumin which represents approximately 60-68 per cent of the total serum proteins. The narrowness or the hand represents a homogeneity and signifies the presence of only one protein component. The last component-the globulin consisting and represents one, in relative mobithat it is hete- this band is comparatively wide suggesting of many components is subjected which have the to electrophoresis, with a mobility mobility. These protein patterns have been shown to be similar to those of the newborn infants, these workers, however, observed in fetus a new protein component migrating between albumin and alpha! The electrophoretic pattern of a newborn infant shows a decreased albumin and beta globulin as compared to an adult pattern. At the time of birth, the concentration of gamma globulin averages that of its mother. Since no new gamma globulin is synthesized because of the absence of synthesizing mechanism In the infant, the plasma level falls until 4-12 weeks. At this time the infant begins to synthesize its own gamma globulin and the plasma level rises as the amount synthesized exceeds the amount catabolized. Normal levels are achieved between 1/2 to 7 yrs (Oberman et al, 1956) and In the premature infants only the albumin fraction is found to be still decreased. This is due to incomplete growth since albumin is the major protein fraction responsible for growth. The values can be directly correlated to the weights at birth and to the socio-economic status of the mother (Kulkarni et al, 1959b) this albumin fraction slowly increases as the age advances and the adult level is reached at the age of about 17 yrs. It is interesting to note that there is no effect of age upon the gamma globulin levels. Males have the same serum electrophoretic pattern as that of the females although the former have slightly higher albumin content.

Predictive value of von Willebrand factor to ristocetin cofactor ratio and thrombin-antithrombin complex levels for hepatic the Coagulation Cascade in Cirrhosis 9 30. Haemostasis unbalance in Pughscored liver cirrhosis: characteristic changes of plasma levels of protein C versus protein S. Association between low-grade disseminated intravascular coagulation and endotoxemia in patients with liver cirrhosis. Hemostasis is the physiologic process that causes bleeding to cease after injury to the vascular wall injury. In chronic and acute liver failure multiple alterations in secondary hemostasis may be present. This concomitant decrease in pro- and anticoagulant factors may explain the weak link between the severity of bleeding in clinical practice and the level of coagulation abnormalities as assessed by conventional coagulation tests that fail to test the contribution of the natural inhibitors of coagulation to clot formation. These studies demonstrated that cirrhotic patients maintain the same capacity to generate thrombin as healthy controls when thrombomodulin, the activator of the anticoagulant protein C, is added to the test mixture. In vivo however, thrombin generation is a function not only of pro- and anti-coagulant factors but also of platelets. Primary and secondary hemostasis therefore are physiologically integrated for thrombin generation and fibrin formation. Abnormalities in platelet number and function are common in patients who have liver disease. Therefore Tripodi and colleagues12 also investigated the effect of these abnormalities on the generation of thrombin. They found that the capacity of platelets to support thrombin generation in cirrhotic patients was indistinguishable from that in healthy subjects when platelet counts were adjusted to similar (normal) levels and thrombomodulin was added to the experiment. Thus, thrombin generation probably is not affected to a great extent in these patients. In line with the aforementioned studies assessing secondary hemostasis, these results now challenge the assumption that in patients who have liver disease alterations in primary hemostasis are inherent to significant hemorrhagic complications. Standard diagnostic tests of primary hemostasis such as the bleeding time traditionally have associated platelet abnormalities with an increased risk of bleeding. In fact, based on this relationship, many centers justify the use of prophylactic measures, including platelet transfusion before invasive procedures (such as liver biopsy or tooth extraction), even though no prospective studies have been conducted to confirm whether such measures are an effective way to prevent bleeding events in patients who have liver disease. Moreover, transfusion of platelets in patients who have liver disease may be associated with serious side effects, such as volume overload, exacerbation of portal hypertension, risk of infection, and risk of transfusion-related acute lung injury. Adhesion to subendothelial adhesive proteins such as collagen requires the synergistic action of several receptors (summarized in. At the same time, platelets start synthesizing thromboxane A2 from arachidonic acid released from the membrane, also resulting in the secondary activation of platelets. Stabilization of the platelet plug is mediated further by the formation of the Platelet and Platelet Function Testing 13.

Finally, the dysfunction of the endothelial system is reviewed, including testing of endothelial function in liver disease. Goulis and colleagues13 postulated the role of bacterial infections through subsequent release of endotoxins in the systemic circulation as critical for triggering variceal bleeding through two distinct pathways. First, endotoxins lead to an increase in portal pressure by contracting hepatic stellate cells through the induction of endothelin. Indeed, infection may lead to abnormalities in coagulation through multiple pathways. Sepsis can cause impairment of platelet aggregation, and production of cytokines in bacterial infections may lead to activation of clotting factors and fibrinolysis. Heparinoids, both exogenous and endogenous, are cleared by the liver, and elevated levels have been reported in cirrhotic patients. Therapeutic implications concerning the endogenous heparinoids in patients who have liver cirrhosis have not yet been identified. Instead, current treatment modalities for uremic bleeding include erythropoietin, desmopressin, and estrogens, which have reduced bleeding complications. Elevated rates of thrombotic complications are thought to emerge as the bleeding tendency is better controlled. The endothelium not only serves as a barrier between blood and the vessel wall but also plays an important role in hemostasis, vessel tone regulation, vascular homeostasis, and inflammatory processes. In response to various mechanical and chemical stimuli, endothelial cells secrete a wide array of substances that mediate these functions. Endothelial dysfunction causes an imbalance between the vasodilator and vasoconstrictor forces, affecting the vascular tone of the circulation on two distinct anatomic levels: the arteries of the intrahepatic microcirculation and the arteries of the splanchnic circulation. Serum levels of intercellular adhesion molecule-1 are increased in cirrhosis87 and are reported to be of prognostic relevance in patients who have liver cirrhosis. The pivotal role of infection in variceal bleeding is well established, and, among other things, it leads to abnormalities in coagulation. One of the pathways through which this occurs is shown to depend on endogenous heparinoids. Furthermore, renal failure may contribute to hemostatic imbalance in cirrhotic patients through so-called ``uremic bleeding. Current treatment options include erythropoietin, desmopressin, and estrogens, which have been shown to reduce bleeding complications in renal failure. Finally, the authors discussed endothelial dysfunction, which is shown to play an important role in the development of portal hypertension in patients who have cirrhosis. Several promising markers of endothelial function in cirrhotic patients have recently become available and should be evaluated in more detail for their clinical use.

Establishing stronger linkages among the tobacco control, global health and development communities has been recognized as an important priority. Regulating new tobacco products also presents a complex set of challenges that will require sustained collaborative and cooperative efforts. They also received instrumental international support from the Bloomberg Initiative to Reduce Tobacco Use partners. Their respective subject matter expertise has allowed the creation of a unique research-to-action tool, bringing compelling evidence into the hands of advocates and policy-makers around the world. The preponderance of available evidence suggests that using current-generation e-cigarettes is substantially less harmful than using tobacco cigarettes. However, there are lingering concerns about the harm from using e-cigarettes, particularly the uncertain longterm effects of nicotine use in the absence of combusted tobacco, and the interactions of heated e-liquid with sensitive lung tissue. There are also questions about whether e-cigarettes might pull ex-smokers back to using nicotine, and some argue that a causal "gateway effect" exists wherein youths begin to smoke tobacco cigarettes due to their exposure to e-cigarettes. E-cigarettes present several regulatory challenges, and policymakers and governments continue to struggle with how to regulate them effectively. The most basic issue is whether these novel nicotine products should be given market access at all. At least 36 countries ban e-cigarette sales altogether, or permit device sales but ban the sale of nicotine e-liquid. This approach is understandable for nations with very low smoking prevalence where introducing a new nicotine product might undermine tobacco control efforts. Most governments are trying a variety of other approaches to gatekeeping market access, ranging from permissive. Consider that many e-cigarette advertisements are blatantly directed at youth, recalling cigarette ads in the recent past. Also, many countries have product safety regulations pertaining to e-liquid contents, child-safe packaging, nicotine quality and concentration, flavors, and other ingredients. Lastly, policymakers will need to consider what regulations should apply to "heat-not-burn" products that heat processed tobacco in a controlled fashion rather than combusting it. They are likely to be more harmful than e-cigarettes because they contain tobacco, and the early evidence shows that they contain considerably higher levels of toxins than do e-cigarettes. There will not be much time to decide: heat-not-burn is already rapidly gaining market share in Japan, and has been introduced in more than 25 countries. More quitting and less initiation of tobacco use contribute to greater individual and societal well-being. Consequently, tobacco companies act in their own interest, for example, by aggressively lobbying and litigating against government tobacco control policies, among other tactics. In its zeal to promote tobacco use, the tobacco industry regularly perpetrates unethical, and often unlawful, interference with life-saving tobacco control policies. Although tobacco companies compete for market share, they often collude to counter government tobacco control efforts, or support front groups to do the job for them. Other strategies involve openly misrepresenting scientific evidence to confuse the public. International donors, such as the Bloomberg Philanthropies, have provided helpful funds for countries that lack capacity or resources to face multi-billion dollar companies in courts. Still, more stable funding mechanisms for legal support to governments are needed. In many places, directing funds from increases in tobacco taxes could help to bridge this gap. The industry has promoted general mistrust toward science - a phenomenon that cripples global progress. These groups amplify industry messages by disguising the messenger, frequently giving policymakers the illusion of a broader coalition. The tobacco industry funds groups ranging from restaurant associations opposed to smoke-free laws, to large international think tanks against tax hikes. These groups repeatedly fail to disclose their funding and sponsorship, deceiving policymakers and the public about their true origin and intentions. The industry secures content consistent with their interests by using advertising dollars to control media messages, by manufacturing information sources, or by ghostwriting pro-tobacco content. When new tobacco control policies are on the agenda, the image of a good "corporate citizen" redirects attention away from the dire consequences of smoking.
