The clinical and histopathological distinction between keratoacanthoma (KA) and squamous cell carcinoma (SCC) is essential, but frequently difficult to make. The utility of CK17 and Ki-67 expression in distinguishing between KA and SCC was investigated. Immunohistochemical staining patterns for CK17 and Ki-67 were evaluated in 24 KA and 27 SCC cases. The pattern of staining was evaluated as central, peripheral or diffuse, according to the basal/peripheral and suprabasal/central cell staining of tumor lobules...

Intramural pregnancy is a rare type of ectopic pregnancy with an unclear etiology. It may be associated with uterine wall injury and/or abnormal uterine conditions, such as adenomyosis, in certain cases. In the present report, a case of intramural pregnancy associated with adenomyosis is discussed. The patient was 34 years old and presented with amenorrhea for 40 days. Ultrasonography and magnetic resonance imaging revealed a mixed echogenic mass located within the posterior wall of the uterine fundus with abundant blood flow...

Pancreatic intraductal papillary mucinous neoplasms (IPMNs) are a type of pancreatic tumor, which have been identified following improvements in diagnostic imaging. However, the malignant transformation of IPMN has been difficult to diagnose clinically. To date, the mechanisms driving the progression of IPMN to cancer remain to be fully elucidated. The present study focused on Stathmin 1 (STMN1), a protein that is associated with the development of various types of cancer. The expression of STMN1 was examined immunohistochemically in tissues from cases of IPMN...

Background Subacromial impingement is a common reason for pain in the shoulder. Treatment is difficult and patients are not able to work for a long time. An increasing number of operative treatments can be observed although conservative treatment is effective, too. There is no study that observed how operative and conservative treatment influence ability to work. Methods 86 persons were included in this prospective study. Surgery was performed with an arthroscopy of the shoulder. Conservative treatment was carried out by a physiotherapist under control of the physician...

Kyung-Chul Choi, Jung Hyun Lee, Jin-Sung Kim, Dong Chan Lee, Choon Keun Park
Background and Study Aims The technique and instrumentation of percutaneous endoscopic lumbar diskectomy (PELD) have significantly improved. Thus its indications have been gradually expanding. Down-migrated disk, in particular, is regarded inaccessible by rigid instrumentation due to poor visualization and limited accessibility. We introduce a combination of transforaminal and interlaminar PELD for extensive down-migrated disk herniation at the L4-L5 level. Patients and Methods In the first case, a 48-year-old man had left L5 radicular pain...

Every surgical problem that increases the likelihood of intraoperative and postoperative complications is considered to be a difficult surgical situation. Based on this definition, Korenkov et al. proposed to classify patients according to the following intraoperative difficulty levels (I to IV): (I) ideal situation (easy to operate, no problems), (II) fairly easy/manageable/simple (some minor difficulties may occur), (III) difficult/problematic (difficult to operate; some operative techniques are considerably more difficult than others), and (IV) very difficult (every operative step is difficult/challenging)...

Ab initio quantum chemistry calculations for systems with large active spaces are noto- riously difficult and cannot be successfully tackled by standard methods. In this letter, we generalize a Green's function QM/QM embedding method called self-energy embedding the- ory (SEET) that has the potential to be successfully employed to treat large active spaces. In generalized SEET, active orbitals are grouped into intersecting groups of few orbitals allowing us to perform multiple parallel calculations yielding results comparable to the full active space treatment...

The heat shock transcription factor 1 (HSF1) has been identified as a therapeutic target for pharmacological treatment of multiple myeloma (MM) However, direct therapeutic targeting of HSF1 function seems to be difficult due to the shortage of clinically suitable pharmacological inhibitors. We utilized the Ugi multicomponent reaction to create a small, but smart library of α-acyl aminocarboxamides, and evaluated their ability to suppress heat shock response (HSR) in MM cells. Using the INA-6 cell line as MM model, and the strictly HSF1 dependent HSP72 induction as a HSR model, we identified potential HSF1 inhibitors...

Virtual molecular catalogs have limited utility if member compounds are (1) difficult to synthesize or (2) unlikely to have biological activity. The Distributed Drug Discovery (D3) program addresses the synthesis challenge by providing scientists with a free virtual D3 catalog of 73,024 easy-to-synthesize N-acyl unnatural α-amino acids, their methyl esters, and primary amides. The remaining challenge is to document and exploit the bioactivity potential of these compounds. In the current work, a search process is described that retrospectively identifies all virtual D3 compounds classified as bioactive hits in PubChem-cataloged experimental assays...

Diaphragmatic laceration is not a rare condition after blunt thoraco-abdominal trauma following road traffic accidents. Diagnosis is sometime difficult and clinical presentation devious. Video-assisted thoracic surgery is a safe approach in order to confirm diagnosis and treat, like in this this case of an 86-year-old lady with grade IV injury.

Motivation: Loops are often vital for protein function, however, their irregular structures make them difficult to model accurately. Current loop modelling algorithms can mostly be divided into two categories: knowledge-based, where databases of fragments are searched to find suitable conformations and ab initio, where conformations are generated computationally. Existing knowledge-based methods only use fragments that are the same length as the target, even though loops of slightly different lengths may adopt similar conformations...

A new Brain-Computer Interface (BCI) technique, which is called a hybrid BCI, has recently been proposed to address the limitations of conventional single BCI system. Although some hybrid BCI studies have shown promising results, the field of hybrid BCI is still in its infancy and there is much to be done. Especially, since the hybrid BCI systems are so complicated and complex, it is difficult to understand the constituent and role of a hybrid BCI system at a glance. Also, the complicated and complex systems make it difficult to evaluate the usability of the systems...

Gulf War Illness (GWI), which affects at least one fourth of the 700,000 veterans deployed to the Gulf War (GW), is characterized by persistent and heterogeneous symptoms, including pain, fatigue and cognitive problems. As a consequence, this illness remains difficult to diagnose. Rodent models have been shown to exhibit different symptomatic features of GWI following exposure to particular GW agents (e.g. pyridostigmine bromide, permethrin and DEET) and/or stress. Preclinical analyses have shown the activation of microglia and astroglia as a pathological hallmark in these mouse and rat models...

OBJECTIVES: Huntington disease (HD) is associated with a variety of cognitive deficits, with prominent difficulties in working memory (WM). WM deficits are notably compromised in early-onset and prodromal HD patients. This study aimed to determine the feasibility of a computerized WM training program (Cogmed QM), novel to the HD population. METHODS: Nine patients, aged 26-62, with early stage HD underwent a 25-session (5 days/week for 5 weeks) WM training program (Cogmed QM)...

BACKGROUND: Endoscopic cubital tunnel release has been proposed as an alternative to open in situ release. However, it is difficult to analyze outcomes after endoscopic release, as only a few small case series exist. METHODS: The electronic databases of PubMed (1960-June 2014) were systematically screened for studies related to endoscopic cubital tunnel release or open in situ cubital tunnel release. Baseline characteristics, clinical scores, and complication rates were abstracted...

Sodium-ion (Na) solid-state electrolytes (SSEs) are critical to address notorious safety issue associated with liquid electrolytes used in the current Na-ion batteries. Fulfilling multiple innovations is a grand challenge but imperative for advanced Na-ion SSE such as a combination of high ionic conductivity and excellent chemical stability. Here, our first-principles and phonon calculations reveal that Na3P1-xAsxS4 (0 ≤ x ≤ 1) is a solid-state superionic conductor stabilized at 0 K by zero-point vibrational energy and at finite temperatures by vibrational and configurational entropies...

Primary pleural myxoid liposarcoma is a rare tumor. Here, we report a primary myxoid liposarcoma occupying the majority of the left thoracic cavity with features suggesting invasion. Computed tomography (CT) at medical check-up incidentally revealed a bulky inhomogeneous fatty mass. The tumor's large size made a prediction of its resectability by preoperative CT difficult. The patient underwent an operation, which revealed that the tumor was attached to the pleura with a thin pedicle; the tumor was resected completely...

BACKGROUND AND PURPOSE: Dysphagia is a well-known complication of acute stroke. Given the complexity of cerebral swallowing control it is still difficult to predict which patients are likely to develop swallowing dysfunction based on their neuroimaging. In Part 2 of a comprehensive voxel-based imaging study, whether the location of a stroke lesion can be correlated with further dysfunctional swallowing patterns, pulmonary protective reflexes and pneumonia was evaluated. METHODS: In all, 200 acute stroke cases were investigated applying flexible endoscopic evaluation of swallowing within 96 h from admission...

The friction cost approach has been proposed as an alternative to the human capital approach in estimating productivity costs. However, it is difficult, in practice, to apply this approach due to limited availability of context-specific data. Using national and firm-level data on vacancy durations sourced from 4 organisations, we estimated vacancy durations, and consequently, length of friction period for the United Kingdom disaggregated by occupational classification. We found comparable estimates to previously reported friction periods elsewhere...
