Adenosine is an endogenous nucleoside that plays a major role in the pathophysiology of airway diseases, such as asthma and chronic obstructive pulmonary disease. It is also an effective drug at terminating supraventricular tachycardia and used for pharmacological stress testing with a relatively safe side effect profile. There is a contraindication for the use of adenosine in patients with asthma and a caution to use in patients with chronic obstructive pulmonary disease. We present a case of a 63-year old female patient who was treated with adenosine and subsequently went into respiratory distress. She was placed on bilevel positive airway pressure and had rapid resolution of symptoms.Clostridium sordellii infections are known to be associated with high morbidity and mortality. To date, only a small number of cases with necrotizing soft tissue infection due to C. Sordellii have been reported. We report a case presented with necrotizing soft tissue infection of the right upper extremity caused by C. sordellii in a patient with known use of injected heroin. Despite broad spectrum antibiotics and surgical debridement, the patient's clinical course became rapidly fatal, within 24 h of admission. C. sordellii necrotizing soft tissue infections are particularly virulent. Even in the context of appropriate surgical debridement, these infections can be rapidly fatal. This case highlights the importance of high suspicion for C. sordellii as potential pathogen of necrotizing soft tissue infection in injection drug users.Peptide receptor radionuclide therapy is a type of molecular radiotherapy that has been used in the treatment of patients with neuroendocrine tumours for over two decades. It is not until recently, however, that it has achieved regulatory approval. The currently approved treatment regimen is a one-size-fits-all scheme, i.e. selleck chemicals llc all patients receive a fixed activity of the radiopharmaceutical (177Lu-DOTATATE) and a fixed number of treatment cycles. Several research groups around the world have studied different approaches of further improving on the results of peptide receptor radionuclide therapy, with many promising retrospective and prospective clinical studies having been published over the years. In this overview, we summarise some of the most promising strategies identified so far.Glioma is one of the most common primary intracranial tumor, but the current treatments of glioma are far from satisfying. As the major treatment option for malignant glioma, chemotherapy has its own disadvantages, including low chemotherapeutic agents delivery across blood-brain barrier (BBB) and lack of specificity. Therefore, new approach permitting glioma targeting ability that can allow an efficient therapeutic delivery into the glioma regions is urgently required. Ligand-mediated liposomes have shown great potential for improving the efficiency of glioma treatment. In our study, the multi-targeting liposomes based on glucose and biotin were constructed for the first time. We synthesized two ligands (Glu3-Chol, Bio2-Chol), prepared three types of modified liposomes (Glu3-Lip, Bio2-Lip and Bio2 + Glu3-Lip) and evaluated the glioma-targeting ability of these liposomes which were using paclitaxel (PTX) as the model drug in vitro. Besides, the uptake mechanism of Bio2 + Glu3-Lip was investigated. PTX-loaded Bio2 + Glu3-Lip (PTX-Bio2 + Glu3-Lip) exhibited satisfactory targeting effect in Bend.3 and C6 cells in vitro, in which the cellular uptake of Bio2 + Glu3-Lip were 4.04- and 3.49-fold more than that of the uncoated liposomes (Lip). The results suggested the multi-targeting liposomes (Bio2 + Glu3-Lip) is a promising formulation for glioma, which was almost consistent with the results of in vivo imaging. In summary, we have designed and fabricated an effective delivery system to treat glioma.Owing to its potential biological relevance, DNA G-quadruplex has been considered as a prospective anti-cancer target. Some known G-quadruplex-interactive N-containing compounds with low cytotoxicity have become prospective anticancer drugs. Here we reported a new type of N-containing alkaloids 3,8a-disubstituted indolizinones, and investigated their substituent effects at 3- and 8a-positions in targeting to DNA c-myc G-quadruplex. And then we used 3-naphtyl-8a-(pyridin-2-yl) substrate I8 as an example, and investigated its ability in targeting to DNA parallel G-quadruplexes in vitro.

Bypass grafting is the standard of care for chronic aorto-iliac occlusive disease (AIOD, aka Leriche Syndrome) but is associated with mortality rates of up to 25% if surgical re-intervention is necessary. Despite a recent shift towards an endovascular-first strategy for TransAtlantic InterSociety Consensus II ("TASC II") C and D lesions, reports from Leriche Syndrome are still limited.

15 high-risk patients (11 male, 4 female), mean age of 60.6 years, with chronic aorto-iliac occlusive disease were retrospectively reviewed. Retrograde approaches via the bilateral femoral arteries for aortic occlusion less than 4cm in length and/or antegrade fashion from the brachial artery for juxtarenal type lesions were made. For the latter, thrombolysis prior to angioplasty was also performed. Intraluminal or if necessary, subintimal angioplasty was performed with deployment of either bare metal stents or stentgrafts in a kissing-stent fashion.

A total of 28 iliac arteries and 14 occluded abdominal aorta were treated with 100% technical success, of which 25% success were achieved by using subintimal technique. Two minor complications occurred, including vascular rupture and distal emboli in one patient apiece, which were successfully managed via endovascular fashion. There were no complications of renal artery emboli. Primary and secondary patency rates at 1, 3 and 5 years were 92.3% and 100%; 83.9% and 100%; and 83.9% and 100%, respectively.

Endovascular therapy for chronic aorto-iliac occlusion has a high technical success rate, with good short- and mid-term primary and secondary patency rates and may provide a valid alternative to surgery for high-risk patients.
