Oscillating heat pipes(OHP)which are constructed from a serpentine-arranged capillary tube possess a desirable aerodynamic form factor and provide for relatively high heat transfer rates via cyclic evaporation and condensation of an encapsulated working fluid with no internal wicking structure required.In last two decades,OHP has been extensively investigated for its potential application in thermal management of various applications.This study presents an experimental investigation on the heat transfer performance of an atypically long finned OHP.The heat transfer performance of the proposed OHP was analyzed and compared with a bare tube OHP with similar overall dimensions.Results show that a unit row of finned OHP filled with n-pentane with fill ratio of 70%can recover up to(400±40)W of heat from a typical waste exhaust air stream.The additional pressure drop due to fins was estimated to be(6.8±2)Pa resulting in an increase of 1–2 W of fan power consumption.The average heat recovery rate via finned OHP was found to be almost 80%more than bare tube OHP filled with same working fluid with same fill ratio.

There are several factors involved in the ability of Borrelia burgdorferi to retain a persistent infection within a mammalian host. These factors of immune evasion include regulation of membrane proteins, variable epitopes of surface proteins, protection against the immune system through tick saliva, the ability to migrate to regions where it is not exposed to the immune system or antibiotics, invagination or invasion within various cells, pleomorphic forms, and the potential to produce biofilms. The window of conventional treatment for Lyme disease is short and has the potential to display different symptoms depending on the strain of Borrelia bugdorferi. These symptoms are dependent on the localization of Borrelia burgdorferi which correlates to the significance of diagnosing Lyme disease early to prevent such a spread throughout the body. Such complications of Borrelia burgdorferi may demand new clinical treatment discoveries for patient fighting the chronic form.

Various kinds of organisms, including viruses, bacteria, trematodes and fungi are known carcinogens that cause cancer. Infectious identification related to cancer may lead to better treatment for both the prevention and targeting of cancer therapy. Although nearly 20% of all cancers are caused by an infection of a microbe, the amount of evidence and information regarding the mechanisms associated with oncogenesis varies dramatically from one organism to the next. This review cannot be exhaustive because we are not aware of all infections worldwide in addition to their potential mechanisms for oncogenesis. More research is required for all of the species mentioned in this review.

Various kinds of immunotherapy treatment for cancer are either available to the public or are in the process of clinical trials. Immunotherapy treatments have the potential to treat cancer with significantly less toxicity than chemotherapy and radiation treatments. An emphasis on cellular infusion as a method of either enhancing the immune system by creating an environment for sequestering the host immune system to attack cancer cells or more directly inserting cells to directly attack cancer cells will be provided in this review. Various forms of cancer vaccines are also discussed in this paper as an important aspect in immunotherapy. This review seeks to describe various methodologies associated with administering immunotherapy in the treatment of cancer.

Adoptive immunotherapy, the therapeutic infusion of ex vivo activated cancer-fighting white blood cells that was pioneered by Dr. Steven Rosenberg over 30 years ago, has become more widespread due to outstanding published research documenting the clinical efficacy of this strategy. Based on the well-established in vivo functions of NK and NKT cells, their integral role in the efficacy of certain chemotherapeutic and immunomodulatory agents, and their direct therapeutic action as displayed in clinical trials, the use of autologous natural killer cell infusions is an appropriate and warranted therapeutic option for the treatment of malignant diseases, especially in patients whose disease is refractory to standard treatments such as chemotherapy and radiation.

Chronic Lyme disease complex describes the burden carried by patients infected with Borrelia burgdorferi as well as other co-infections or secondary co-infections (opportunistic infections). These infections can cause a significant burden on patients more so than Lyme disease alone. Along with the many underdiagnosed cases of Lyme disease throughout the world exists numerous undiagnosed co-infection and secondary co-infections leading to debilitating symptoms for many patients. The potential for co-infections varies by location as well as to the exposure to various species of ticks. Since there is potential for patients to experience several tick bites including those of different species, additional microorganisms also commonly transmitted via tick bite are included that are typically left out of the conversation of potential Borrelia burgdorferi co-infections. The most common co-infections of Lyme disease include anaplasmosis, babasiosis, bartonellosis and ehrlichiosis. Secondary co-infections or opportunistic infections commonly seen in patients with Lyme disease are also discussed. By helping to establish a comprehensive list of infections associated with Chronic Lyme disease complex may in fact help patients receive a proper diagnosis in order to administer the much needed comprehensive treatments patients deserve.

Semiconductor quantum dots(QDs)have shown great promise as fluorescent probes for molecular,cellular and in vivo imaging.However,the fluorescence of traditional polymer-encapsulated QDs is often quenched by proton-induced etching in acidic environments.This is a major problem for applications of QDs in the gastrointestinal tract because the gastric(stomach)environment is strongly acidic(pH 12).Here we report the use of proton-resistant surface coatings to stabilize QD fl uorescence under acidic conditions.Using both hyperbranched polyethylenimine(PEI)and its polyethylene glycol derivative(PEG-grafted PEI),we show that the fl uorescence of coreshell CdSe/CdS/ZnS QDs is effectively protected from quenching in simulated gastric fluids.In comparison,amphiphilic lipid or polymer coatings provide no protection under similarly acidic conditions.The proton-resistant QDs are found to cause moderate membrane damage to cultured epithelial cells,but PEGylation(PEG grafting)can be used to reduce cellular toxicity and to improve nanoparticle stability.
