This paper presents a spatial encryption technique for secured transmission of data in networks. The algorithm is designed to break the ciphered data packets into multiple data which are to be packaged into a spatial template. A secure and efficient mechanism is provided to convey the information that is necessary for obtaining the original data at the receiver-end from its parts in the packets. An authentication code (MAC) is also used to ensure authenticity of every packet. For More Biomedical Journals Publishers
Leiomyoma and leiomyosarcome (LMS) appear as two stages of tumor progression process of a transformed smooth muscle cell. Obesity is a well-established risk factor of leiomyoma. The connection between both of them are not well understood. The involvement of obesity in this transformation needs more investigation to be highlighted. Here, we discussed from a tumor immunology perspective, by focusing on the microenvironment immunosuppression that, probably, allows LMS to escape the antitumor immune response.

Necrotising fasciitis are uncommon and remain a devastating disease, with an overall incidence of 0.24-0.4 per 100,000 adults [1]. Delays in instigation of appropriate treatment are associated with significant long-term morbidity with mortality ranging from 9% to more than 25% [2]. Early and repeated debridement of affected planes in combination with use of broad-spectrum antibiotics improves overall outcome [3]. This case study looked at a sudden incidence of a superbug which had consumed 17-20cm wide and 4-5cm deep of flesh within two days of presentation of illness in a 43 year old female.

The breakthrough for dental laser systems came in the mid 1990’s. Among the various laser types with corresponding wavelengths, Er:YAG laser systems quickly began establishing themselves as compact and versatile additions to the dentist’s repertoire, predominantly for performing hard tissue applications. Research has shown that their wavelengths are ideally suited for both soft and hard tissue procedures due to their high absorption in water and hydroxyl apatite. Therefore Er YAG laser is considered one of the most versatile with regard to the number of possible treatment options, as their wavelength can be effectively used in the field of soft and hard tissue surgery, periodontics, endodontics, implantology, cavity preparation, and tooth whitening. The versatility of the instrument, combined with the latest achievements in Er YAG laser technology, compact design and affordability, should appeal to dental professionals seeking to optimize the procedures they currently perform and expand the number of services they offer.

The pleiotropy of melatonin is a reason for using this hormone or synthetic melatonergic agonists for testing their suitability in various diseases and disorders. However, it is important to remain aware that many preclinical findings cannot be translated to humans, because of the different relationship between melatonin and sleep or activity in diurnally compared to nocturnally active mammals. Other uncertainties concern the dual role of melatonin as an either anti- or proinflammatory agent, depending on conditions. A particular problem has emerged by findings on prodiabetic actions of melatonin in humans, which strongly contrast with antidiabetic results obtained in rats. As these undesired actions are gradually receptor subtype-dependent, it may be worthwhile to test in the future agonists that are more strongly subtype-selective.

Microgravity in space can cause various problems in different biological systems. One of the most prominent and well recognized physiological challenges accompanying an extended spaceflight is the reduction in bone mass [1]. However, the underlying mechanisms of this phenomenon are still elusive. Primary cilium is a solitary and special organelle that emanates from the surface of most mammalian cells, which is anchored to the cell by mother centriole during the interphase and G0 of cell cycle [2]. For a long time, primary cilium was considered as a vestigial organelle. Until recently it was found that primary cilium provided a means of sequestering the centriole, so as to inhibit cell division. More significantly, a variety of receptors, ion channels and transporter proteins have been localized to the cilium, which has been proved as a key coordinator of signaling pathways to respond mechanical and chemical stimuli [3,4]. Primary cilium has been proved as a mechanosensor to regulate bone formation both in osteocytes and osteoblasts. It can act as a sensory organelle to receive extracellular signals and change its orientation to translate mechanical stimuli into biochemical and transcriptional changes, and as a result, bone formation is activated [5,6]. Inspired by established role as a mechanosensor, the role of primary cilium in microgravity induced bone loss must be studied. For More: Biomedical Open Access Journals
Immunofluorescence image of primary cilium.Primary cilium were stained by acetylated α-tubulin (green).The basal bodies were stained by γ-tubulin (red), and the nuclei were stained with DAPI (blue).
A 54-year-old man presented with a 6-hour history of acute typical retrosternal chest pain that occurred during minor exertion and was persistent from the start and not relieved by analgesics. His medical history was unremarkable, he was a heavy smoker. His clinical examination was unremarkable. His electrocardiogram (ECG) showed ST segment elevation in the inferior leads with PR depression in the anterior leads. His chest X-ray (CXR) lead (Figure 1) to a suspicion of intra-pericardial collection of air. His laboratory results were all normal except for mild elevation in cardiac enzymes. Echocardiography showed normal study, the suspicion of the intra-pericardial air collection had led us to do a chest computed tomography (CT) (Figure 2) which revealed the presence of air inside the pericardium.

The blood transfusion is an essential part of modern medical care. Used properly can save lives. Throughout the world, the centers that make blood products strive to provide safe of them, since the process of the transfusion could be without risks. At this point is essential the rational use of the same, imposing the need to balance the benefits and potential side effects that could produce like allergic and hemolytic reactions, metabolic processes, effects on cellular immunomodulation, lung damage or transmission of infectious diseases (HIV, HBV and HCV, among others).
