In this paper we examine the factors contributing to the emergence of leadership in a group, and we explore the relationship between the role of the leader and the behavioural capabilities of other individuals. We use a simulation technique where a group of foraging robots must coordinate to choose between two identical food zones in order to forage collectively. Behavioural and quantitative analysis indicate that a form of leadership emerges, and that groups with a leader are more effectivedoi:10.1371/journal.pone.0137234 pmid:26340449 pmcid:PMC4560398 fatcat:s2q4wacmdvgcbioudwx4pzsot4

Moyamoya angiopathy (MMA) is a peculiar cerebrovascular condition characterized by progressive steno-occlusion of the terminal part of the internal carotid arteries (ICAs) and their proximal branches, associated with the development of a network of fragile collateral vessels at the base of the brain. The diagnosis is essentially made by radiological angiographic techniques. MMA is often idiopathic (moyamoya disease-MMD); conversely, it can be associated with acquired or hereditary conditionsdoi:10.3390/jcm10163628 pmid:34441923 pmcid:PMC8397113 fatcat:vfhqaipsuzf7lg7ec3nhdptzty

MMD and MMS also have similar clinical expressions, including, above all, ischemic and hemorrhagic strokes, then headaches, seizures, cognitive impairment, and movement disorders. The available treatment strategies are currently shared between idiopathic MMD and MMS, including pharmacological and surgical stroke prevention treatments and symptomatic drugs. No pharmacological treatment able to reverse the progressive disappearance of the ICAs has been found to date in both idiopathic and syndromic cases. Antithrombotic agents are usually prescribed in ischemic MMA, although the coexisting hemorrhagic risk should be considered. Surgical revascularization techniques, which are currently the best available treatment in symptomatic MMA, are associated with good long-term outcomes and reduced ischemic and hemorrhagic risks. Given the lack of dedicated randomized clinical trials, current treatment is mainly based on observational studies and physicians' and surgeons' expertise.
Liposomes containing monosialoganglioside (G") or polyethylene glycol (PEG) lipid derivatives have prolonged circulation in the blood. This favours liposome extravasation to tumour sites. In this report it is shown that inclusion of G", PEGS,-DPPB or PEGmxrDPPE in liposomes containing biotin-DPPE signiticantly diminished the ability of vesicles to bind to streptavidin in vitro. Steric inhibition due to the bulky head group of these lipids was least for biotin-DPPE liposomes contaming C&i.doi:10.1016/0014-5793(93)80509-s pmid:8405439 fatcat:rdzv5unv6ffmfevmyfw7rqtpty

Using fluorescent microscopic techniques, liposomes contaming both G" and biot~-DPPE were detected within ex~-vault spaces in tumours. In addition it was shown that biotin-DPPE in G&iposomes bound streptavidin in situ. These results suggest that G"-liposomes containing biotin-DPPE have potential use as diagnostic or therapeutic reagents in pre-targeting applications dependent on the high-a&&y interaction of biotiu with streptavidin.

In multiple sclerosis (MS) patients, trigeminal neuralgia (TN) represents a challenging syndrome to treat, often refractory to medical therapy and percutaneous techniques. Despite the frequent lack of a neurovascular conflict, the trigeminal nerve's axons are often damaged, with the myelin sheath permanently degenerated, thus explaining the difficulty in treating TN in MS.The authors illustrate trigeminal interfascicular neurolysis (the combing technique) to control refractory recurrent TN indoi:10.3171/2020.5.focvid203 fatcat:dy4rscyrtvggtjx22tm4axao7m

Peripheral schwannomas can be misdiagnosed or mistreated as they can mimic other subcutaneous lesions, leading to wrong diagnosis and, therefore, to improper treatment. Case Description: A 23-years-old male presented a painful growing nodule at the left popliteal fossa, with distally irradiated pain. A first magnetic resonance imaging depicted a heterogeneous lesion between common peroneal and sural nerves but, surprisingly, the patient was submitted to perilesional injection of ozone-oxygendoi:10.25259/sni_296_2020 pmid:33365176 pmcid:PMC7749957 fatcat:nnsmeok5brbuhkwmz4xbpf6hau

He finally underwent surgery but, intraoperatively, inter-fascicular fibrous adherences were noticed, making the tumor removal more difficult and riskier. The histopathological diagnosis was of schwannoma with areas of foreign body reaction. Conclusion: The injection of ozone or other substances within a subcutaneous swelling should be avoided, before a complete imaging assessment; because of such swelling could be a peripheral nerve schwannoma. The correct assessment of a lesion of the limbs determining radiating pain should be carefully demanded to a thorough history, clinical examination, and appropriate imaging technique. To avoid incorrect management, the treatment of such tumors should be performed in the first place by dedicated equips with proven expertise in this field.
