Wei Ding, Yinjia Ding, Hua Jiang
BACKGROUND: Although reduction mammaplasty is one of the most common procedures in plastic surgery, it is associated with some serious complications, especially in cases of severe hypertrophy or advanced ptosis, including necrosis of the nipple and areola, absence of normal sensation of the nipple-areolar complex, and loss of lactational function for future nursing. A thorough understanding of the breast anatomy is vital for successful reduction mammaplasty. This article describes the blood supply and innervation of the breasts, and introduces a modified round block technique for reduction mammaplasty based on this anatomy...

Opioid addiction, including addiction to heroin, has dramatically increased in the last decade. The cost and pervasiveness of heroin addiction, including resistance to recovery from addiction, provide a compelling basis for developing novel therapeutic strategies. Deep brain stimulation may represent a viable alternative strategy for the treatment of intractable heroin addiction particularly in individuals who are resistant to traditional therapies. Here, we provide preclinical evidence of the therapeutic potential of high-frequency stimulation of the subthalamic nucleus (STN HFS) for heroin addiction...

Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract, with increasing incidence worldwide. Crohn's disease might result from a complex interplay between genetic susceptibility, environmental factors, and altered gut microbiota, leading to dysregulated innate and adaptive immune responses. The typical clinical scenario is a young patient presenting with abdominal pain, chronic diarrhoea, weight loss, and fatigue. Assessment of disease extent and of prognostic factors for complications is paramount to guide therapeutic decisions...

Currently, anticoagulants would be used to prevent thrombosis. Thrombin is an effector enzyme for haemostasis and thrombosis. We designed a direct thrombin inhibitor peptide (DTIP) using molecular simulation and homology modelling and demonstrated that the C-terminus of DTIP interacts with exosite I, and N-terminus with the activity site of thrombin, respectively. DTIP interfered with thrombin-mediated coagulation in human, rat and mouse plasma (n=10 per group) and blocked clotting in human whole blood in vitro...

The development of first cellular structures played an important role in the early evolution of life. Early evolution of life probably took place on a molecular level in a reactive environment. The iron-sulfur theory postulates the formation of cell-like structures on catalytic surfaces. Experiments show that H2S together with FeS and other metallic centers drive auto-catalytic surface reactions, in which organic molecules such as pyruvic and amino acids occur. It is questionable which mechanisms are needed to form cell-like structures under these conditions...

PURPOSE: The propose of this discussion is to explore the role of the case manager to empower and motivate clients, especially those who appear "stuck" or resistant to change. Drawing upon the experiences of case managers across many different practice settings, the article addresses how case managers can tap into the individual's underlying and sometimes deep-seated desires in order to foster buy-in for making even small steps toward achieving their health goals. The article also addresses how motivational interviewing can be an effective tool used by case managers to uncover blocks and barriers that prevent clients from making changes in their health or lifestyle habits...

While computerised tomography (CT) may have been the first imaging tool to study human brain, it has not yet been implemented into clinical decision making process for diagnosis of Alzheimer's disease (AD). On the other hand, with the nature of being prevalent, inexpensive and non-invasive, CT does present diagnostic features of AD to a great extent. This study explores the significance and impact on the application of the burgeoning deep learning techniques to the task of classification of CT brain images, in particular utilising convolutional neural network (CNN), aiming at providing supplementary information for the early diagnosis of Alzheimer's disease...

The neuropeptide Y2 receptor (Y2 R) is involved in various pathophysiological processes such as epilepsy, mood disorders, angiogenesis, and tumor growth. Therefore, the Y2 R is an interesting target for drug development. A detailed understanding of the binding pocket could facilitate the development of highly selective antagonists to study the role of Y2 R in vitro and in vivo. In this study, several residues crucial to the interaction of BIIE0246 and SF-11 derivatives with Y2 R were investigated by signal transduction assays...

Postoperative residual neuromuscular block has been recognized as a potential problem for decades, and it remains so today. Traditional pharmacologic antagonists (anticholinesterases) are ineffective in reversing profound and deep levels of neuromuscular block; at the opposite end of the recovery curve close to full recovery, anticholinesterases may induce paradoxical muscle weakness. The new selective relaxant-binding agent sugammadex can reverse any depth of block from aminosteroid (but not benzylisoquinolinium) relaxants; however, the effective dose to be administered should be chosen based on objective monitoring of the depth of neuromuscular block...

BACKGROUND: Little data exist on the long-term prognosis of patients with inflammatory bowel disease (IBD) after stopping TNFα-blocking therapy in deep remission. Existing data indicate that approximately 50% of patients on combination therapy who discontinued TNFα-blockers are still in remission 24 months later. The aims of this follow-up analysis were to evaluate the long-term remission rate after cessation of TNFα-blocking therapy, the predicting factors of a relapse and the response to restarting TNFα blockers...

Rhinoplasty is a difficult procedure to record for several reasons which include the narrow, dark and deep surgical field cluttered with many instruments, and the heads and hands of the surgical team often blocking the view. This study discusses 13 rhinoplasty cases that were recorded using the authors' technique. A three-minute, unedited segment was extracted from the mid-portion of each surgical case, and that footage was evaluated by three specialist examiners. Results indicate that the authors' technique can offer a effective solution in the video recording of the nasal-dorsal part of a rhinoplasty...
