BACKGROUND Pathological complete response(pCR) is rare in hormone receptor-positive(HR+)HER2-negative breast cancer(BC) treated with either endocrine therapy(ET) or chemotherapy. Radical resection of locoregional relapse, although potentially curative in some cases, is challenging when the tumor invades critical *** oral cyclin-dependent kinase 4/6 inhibitor palbociclib in combination with ET has obtained a significant increase in objective response rates and progression-free survival in patients with advanced BC and is now being evaluated in the neoadjuvant setting. We present a clinical case of a patient with an inoperable locoregional relapse of HR+ HER2-negative BC who experienced p CR after treatment with *** SUMMARY We report the clinical case of a 60-year-old patient who presented with an inoperable locoregional relapse of HR+, HER2-negative BC 10 years after the diagnosis of the primary tumor. During a routine follow-up visit, breast magnetic resonance imaging and positron emission tomography/computed tomography revealed a 4-cm lesion in the right subclavicular region, infiltrating the chest wall and extending to the subclavian vessels, but without bone or visceral involvement. Treatment was begun with palbociclib plus letrozole, converting the disease to operability over a period of 6 mo. Surgery was performed and a p CR achieved. Of note, during treatment the patient experienced a very uncommon toxicity characterized by burning tongue and glossodynia associated with dysgeusia, paresthesia, dysesthesia, and xerostomia. A reduction in the dose of palbociclib did not provide relief and treatment with the inhibitor was thus discontinued, resolving the tongue symptoms. Laboratory exams were unremarkable. Given that this was a late relapse, the tumor was classified asendocrine-sensitive, a condition associated with high sensitivity to *** This case highlights the potential of the cyclin-dependent kinase 4/6 inhibitor pl

The neuromodulatory peptide somatostatin(somatotropin release inhibiting factor,SRIF)-14 acts at multiple levels through five SRIF receptor subtypes(sst1 to sst5).SRIF-28 is also derived from a common propeptide translated from a single SRIF gene,although SRIF-14 is the predominant form in the mammalian nervous *** to its short half-life,synthetic SRIF analogs have been developed over the years and are available for therapeutic approaches.

用于热能管理的复合相变材料(C-PCMs)利用其一个或多个低熔点活性相的可逆相变(如熔化—凝固)存储和释放热能作为潜热。同时,高熔点的惰性相可以提供额外的性能,如定形性和改善的导热性。从难混溶合金中可获得具有这些特征的全金属复合材料体系。本文将热力学计算和实验测试相结合,探讨二元(Al-In,Al-Sn,Al-Bi和Cu-Bi)和三元(Al-In-Sn和Al-Bi-Sn)难混溶合金在100~300℃的温度范围内用作C-PCMs的潜力。结果表明,将这两种方法相结合对于全面理解复合体系和找到满足设计需求的最佳解决方案十分必要,它克服了“试错”法浪费时间的弊端,并为模拟提供了高质量的数据。

Extract The contrary but interrelated processes of axon degeneration and regeneration are the yin and yang of many neurodegenerative conditions. Here we discuss recent evidence for metabolic cross-talk between glia and injured axons regulating these processes. We especially focus on potential bioenergetic mechanisms as to how axon-flanking glia may promote regeneration.

作者： elisabetta Catalani Federica Silvestri Davide Cervia Department for Innovation in Biological Agro-food and Forest Systems(DIBAF)Universitadegli Studi della Tuscialargo dell’UniversitasncViterboItaly

Due to the high degree of conservation of genes and mechanisms, the fruit fly Drosophila melanogaster is a powerful experimental in vivo tool to investigate complex diseases, thus complementing traditional vertebrate systems. Drosophila is also an advantageous system regarding the animal husbandry and the short generation time and lifespan.
