Feeding dysfunction is a frequent presenting symptom of eosinophilic esophagitis(EoE). Here we present 3 children of various ages whose manifestations of EoE associated feeding dysfunction led to significant and life altering impact on their growth and development. Early identification of presenting symptoms of EoE will allow for prompt diagnosis and initiation of appropriate treatments. Recognition of salient features of dysfunction and treatment by feeding therapists and nutritionists led to symptom resolution and growth.

Calcium-sensitive protein mLC1 as a possible modulator of the astrocyte functional state

Neural Regeneration Research 2025年第7期20卷 2008-2010页

作者： Elena Ambrosini angela Lanciotti maria Stefania Brignone Department of Neuroscience Istituto Superiore di SanitàRomeItaly

Astrocytes,the main population of glial cells in the central nervous system(CNS),exert essential tasks for the control of brain tissue homeostasis,supporting neuron and other glial cell activity from the developmental stage to adult *** maintain the optimal functionality of the brain,astroglial cells are particularly committed to reacting to every change in tissue homeostatic conditions,from mild modifications of the physiological environment,a process called astrocyte activation,to the more severe alterations occurring in pathological situations causing astrocyte reactivity or reactive astrogliosis(Escartin et al.,2021).During these reactive states,astrocytes mount an active,progressive response encompassing morphological,molecular,and interactional remodeling,leading to the acquisition of new functions and the loss of others,whose intensity,duration,and reversibility are dependent on the nature of the stimulus and regulated in a context-specific manner.

Even though the mTOR complex has been known for decades as a nutrient sensor,being thus in focus for drug targeting in metabolic disease and cancer metabolism,it has remained puzzling how it is able to get a sense of glucose availability in ***,a small metabolite of the glycolytic pathway,dihydroxyacetone phosphate,has been identified by Sabatini and his coworkers,who show how mTORC1-activity is regulated in glucose-starved and replenished cancer cells.

Review of single incision laparoscopic surgery in colorectal surgery

World Journal of Gastroenterology 2015年第38期21卷 10824-10829页

作者： Nisreen madhoun Deborah S Keller Eric m haas Colorectal Surgical Associates Division of minimally Invasive Colorectal Surgery Department of SurgeryUniversity of Texas Medical School at Houston Houston methodist Hospital

As surgical techniques continue to move towards less invasive techniques,single incision laparoscopic surgery(SILS),a hybrid between traditional multiport laparoscopy and natural orifice transluminal endoscopic surgery,was introduced to further the enhanced outcomes of multiport laparoscopy. The safety and feasibility of SILS for both benign and malignant colorectal disease has been proven. SILS provides the potential for improved cosmesis,postoperative pain,recovery time,and quality of life at the drawback of higher technical skill required. In this article,we review the history,describe the available technology and techniques,and evaluate the benefits and limitations of SILS for colorectal surgery in the published literature.

mitochondrial transcription factor A （TFAm）： one actor for different roles

引用

Frontiers in Biology 2012年第1期7卷 30-39页

作者： angela m. S. LEZZA Department of Biochemistry and molecular Biology ＇E. Quagliariello University of Bari Aldo Moro Bari Italy

mitochondrial Transcription Factor A （TFAm） is a nuclear-encoded factor present in mitochondria from allkinds of animals, even with a homologous form in yeast, which has strongly and progressively gained an eminent relevance in the regulation of mitochondrial DNA （mtDNA） functions. This is due to the various functions performed by the protein, which cover a very wide scenario including： replication, transcription, maintenance and eventually repair of mtDNA molecules. In consideration of so many different roles it plays, it can be understood there is a deep interest in its regulation of expression and activity as well as its eventual involvement in pathologies related to a decreased functionality/presence of the mitochondrial genome and the consequences of TFAm induced overexpression.

Designing the new generation of intelligent biocompatible carriers for protein and peptide delivery

Acta Pharmaceutica Sinica B 2018年第2期8卷 147-164页

Therapeutic proteins and peptides have revolutionized treatment for a number of diseases, and the expected increase in macromolecule-based therapies brings a new set of challenges for the pharmaceutics field. Due to their poor stability, large molecular weight, and poor transport properties,therapeutic proteins and peptides are predominantly limited to parenteral administration. The short serum half-lives typically require frequent injections to maintain an effective dose, and patient compliance is a growing issue as therapeutic protein treatments become more widely available. A number of studies have underscored the relationship of subcutaneous injections with patient non-adherence, estimating that over half of insulin-dependent adults intentionally skip injections. The development of oral formulations has the potential to address some issues associated with non-adherence including the interference with daily activities, embarrassment, and injection pain. Oral delivery can also help to eliminate the adverse effects and scar tissue buildup associated with repeated injections. However, there are several major challenges associated with oral delivery of proteins and peptides, such as the instability in the gastrointestinal(GI)tract, low permeability, and a narrow absorption window in the intestine. This review provides a detailed overview of the oral delivery route and associated challenges. Recent advances in formulation and drugdelivery technologies to enhance bioavailability are discussed, including the co-administration of compounds to alter conditions in the GI tract, the modification of the macromolecule physicochemical properties, and the use of improved targeted and controlled release carriers.
