We present a case of open surgical repair of an aortic arch pseudoaneurysm (AAP) without the use of hypothermic circulatory arrest in a patient with low ejection fraction and associated coronary artery disease (CAD) and discuss some issues regarding the management of this case.

A 69-year-old male with multiple pathologies and history of angina pectoris was transferred to our center from a local hospital with an initial diagnosis of non-ST-segment elevation myocardial infarction. Coronary angiography revealed stenotic lesions affecting all three coronary arteries. Multislice 3D contrast-enhanced computed tomography (CT-scan) revealed a 36 × 27 mm AAP. Endovascular stent-grafting was deemed to be unsuitable due to hostile landing zone. Therefore, the heart team decided for simultaneou treatment of the AAP and percutaneous therapy of CAD. The AAP was excised, and repair was performed with a Dacron patch on beating heart. After the surgical procedure, PCI with drug-eluting stents (DES) was performed on the right coronary artery (RCA) and the left circumflex artery (LCx) in the operating room. The patient's postprocedural course was uneventful and after thirteen days, he was discharged in good shape. 3D CT-scan performed after three month showed no residual AAP.

We established this approach as being the most suitable for our case based on favorable circumstances such as stable CAD, beating heart procedure with low impact on myocardial ischemia, the impossibility of successful placement of an endovascular stent-graft, the presence of a pseudoaneurysm neck with minimum calcification.

We consider the best approach for individual cases is tailoring the treatment plan and the procedure to the patient's specific anatomy and pathology.

Intramuscular abscesses, particularly in the biceps brachii, are an extremely rare phenomenon. When present they are usually secondary to trauma, intramuscular injections, or systemic disease.

A 56 year old diabetic woman presented to our emergency department with a 3 day history of fever, cough, and a painful left shoulder. Although she had a mechanical fall 2 weeks prior, she denied any pain in her shoulder immediately after the fall. She also denied any history of drug abuse or recent intramuscular injection. On examination she looked acutely unwell and was in acute septic shock requiring inotropic support. Computed tomography of her shoulder showed a large intramuscular abscess in her left biceps brachii muscle. She was immediately taken to the operating theatre for open exploration and washout of the abscess. The multiloculated abscess was tracking into the glenohumeral joint. Post operatively she showed significant clinical improvement and after a 2 week course of intravenous antibiotics recovered well and was discharged from hospital.

Intramuscular abscesses are usually seen in patients who are immunocompromised. Intramuscular needle injections and haematomas secondary to trauma are also risk factors. To the best of our knowledge, there have only been 4 published reports in the English literature of intramuscular abscess formation in the biceps brachii.

We report a case of a seemingly spontaneous intramuscular biceps abscess in a diabetic patient presenting with septic shock.

Despite all the progress made in the functional characterization of P2Rs, purinergic signaling research is still limited by the lack of selective or efficient ligands for different receptor subtypes. In this sense, several molecules have been tested towards these receptors as agonists or antagonists. Historically, natural products have always been sources of new bioactive substances for diverse purposes. However, compared to synthetic molecules, the number of natural products assessed for P2R ligands is still low. In this review, we present examples of studies that demonstrated plant natural products acting directly on P2R and modulating their functionality. In some cases, we highlight that the pharmacological activity previously described for the original organism could be correlated to an agonist or antagonist activity of a specific natural product on these receptors. These examples reinforce the need for more studies to investigate the pharmacological potential of new or known natural compounds targeting P2 receptors.A phytochemical study on a 70% EtOH extract of dried roots of Polygonum multiflorum resulted in the isolation of four undescribed stilbene glucosides, namely multiflorumisides HK (1-4). The structures of the natural products were elucidated by 1D and 2D nuclear magnetic resonance (NMR) as well as mass spectroscopy analyses. Stem Cells inhibitor Among them, multiflorumiside J (3) and multiflorumiside K (4) belong to rare tetramer stilbene glucosides. Moreover, the in vitro inhibitory activities against protein tyrosine phosphatase 1B (PTP1B) were evaluated and the putative biosynthetic pathway was proposed. Notably, compounds 1-4 showed the inhibitory activity against PTP1B with the IC50 values of 1.2, 1.7, 1.5 and 4.6 μm, respectively. Based on the obtained results, stilbene glucosides could be the potential PTP1B inhibitors of P. multiflorum.Thirteen compounds were isolated from the methanolic extract of the leaves of Androcymbium palaestinum Baker (Colchicaceae). Of these, three were new, two were new natural products, and eight were known. The new isolated compounds were (+)-1-demethylandrocine (5), (-)-andropalaestine (8), and (+)-2-demethyl-β-lumicolchicone (10), while the new natural products were (+)-O-methylkreysigine-N-oxide (3) and (+)-O,O-dimethylautumnaline (9). Moreover, two known compounds are reported for the first time from this species, specifically (-)-colchicine (11) and (-)-3-demethyldemecolcine (13). The structures of the isolated compounds were elucidated using a series of spectroscopic and spectrometric techniques, principally HRESIMS, 1D-NMR (1H and 13C NMR) and 2D-NMR (COSY, edited-HSQC, and HMBC). ECD spectroscopy was used for assigning the absolute configurations of compounds 3, 5, and 10. The cytotoxic activities of the isolated compounds were evaluated using the MDA-MB-435 (melanoma), MDA-MB-231 (breast), and OVCAR3 (ovary) cancer cell lines.
