Vertebral body replacements with newly-designed ceramic prostheses were successfully applied in eight patients with metastatic tumors and multiple myelomas of the cervical vertebrae. All patients suffered from severe neck pain and/or paralysis due to a collapsing of the vertebral body in the preoperative state. As a re... |
The present study comprehensively explores alternative mechanistic pathways for the intramolecular hydroamination of the prototype 2,2-dimethyl-5-penten-1-amine aminoalkene (1) by bis(ureate)Zr(IV)(NMe(2))(2)(HNMe(2)) (2), which proceeds through a Zr(IV)(NHR)(2) intermediate using density functional theory (DFT) calcul... |
The aim of this study was to characterize and compare the morphological and histomorphometric characteristics of the pectoral fascia, fascia lata and ventral rectus sheath. Twenty cadaveric samples of these fascias were analyzed and stained with hematoxylin and eosin, orcein, Van Gieson, Masson's trichrome and Verhoeff... |
The potassium homeostatic system is very tightly regulated. Recent studies have shed light on the sensing and molecular mechanisms responsible for this tight control. In addition to classic feedback regulation mediated by a rise in extracellular fluid (ECF) [K(+)], there is evidence for a feedforward mechanism: Dietary... |
An inland terminal, or dry port, is one of main facilities in the logistical network of maritime transportation as it helps provide access between hinterland and the rest of the world via the seaports. While the impact of these inland terminal on the efficiency of multimodal transportation has recently become more evid... |
Rat embryos explanted at 9 1/2 or 11 1/2 days of gestation and cultured in rotating bottles were subjected to a number of agents. Embryos explanted at 9 1/2 days (head-fold stage) and incubated for 48 h at 40.5 degrees C were retarded and abnormal and these effects were more severe in embryos cultured at 41 degrees C. ... |
Review question / Objective: At present, risk factors for readmission after pulmonary resection in patients with lung cancer are still not fully elucidated, and related studies have shown inconclusive results. We conducted a meta-analysis of the existing literature with the aim of clarifying the risk factors for readmi... |
BACKGROUND |
Hearing preservation is a goal for many patients with vestibular schwannoma. We examined pretreatment magnetic resonance imaging (MRI) and posttreatment hearing outcome after stereotactic radiosurgery. |
METHODS |
From 2004 to 2014, a cohort of 125 consecutive patients with vestibular schwannoma (VS) treated via stereotactic radiosurgery (SRS) were retrospectively reviewed. MRIs containing three-dimensional constructive interference in steady state or equivalent within 1 year before treatment were classified by two radiologists ... |
RESULTS |
Sixty-one patients met criteria for inclusion. Most had tumors in the distal internal auditory canal (55%), separated from the brainstem (63%), oval shape (64%) without cysts (86%), and median volume of 0.85 ± 0.55 cm. Pretreatment audiograms were performed a median of 108 ± 173 days before stereotactic radiosurgery; 3... |
CONCLUSIONS |
Decreased cochlear CISS signal may indicate a tumor's association with the cochlear neurovascular bundle, influencing endolymph protein concentration and creating an inability to preserve hearing. This important MRI characteristic can influence planning, counseling, and patient selection for vestibular schwannoma treat... |
Medication administration using bar-code medication administration technology enhances the verification of medication administration rights. Nurses' compliance with bar-code medication administration procedure is essential to maximize the benefits. This study evaluated the current rate of nurses' compliance with bar-co... |
Allison, Messick, and Goethals have recently shown that people see themselves as more likely to perform desirable behaviors and less likely to perform undesirable behaviors than others and that this effect is stronger for fair/unfair (moral/immoral) than intelligent/unintelligent behaviors. The present study examined t... |
Commentary It is generally acknowledged that infantile spasms (IS) are a devastating disease with a poor prognosis. Hormonal preparations in the form of ACTH or oral corticosteroids, as well as vigabatrin, are well-established treatments (1–4). The cessation of spasms is achieved in 30 to 93 percent of patients and doe... |

Findings revealed a higher percentage of substantiated physical abuse investigations involving the most harmful subtype “hit with object,” greater ... |
BACKGROUND |
The expression of a multidrug resistance associated protein (MRP) has been investigated in a variety of human tumors. However, there is a lack of data regarding its expression in germ cell testicular tumors (GCTTs). |
PATIENTS AND METHODS |
MRP expression was examined by immunohistochemistry (IHC) using mouse monoclonal antibody (MRPm6) against human MRP in 56 testis cancer specimens. This antigen was also correlated with the histology, metastatic behavior, clinical stage and tumor suppressor protein p53 immunostaining of GCTTs. |
RESULTS |
All testis tumors, regardless of their histology, metastatic status and clinical stage gave positive signals. MRP was positive not only in the cytoplasm but, very interestingly, in the nuclei. |
CONCLUSION |
Our results suggested that ala GCTTs express high levels of MRP protein with no relation to any of clinicopathological variables investigated here. Since germ cell tumors are very sensitive to chemotherapy, the role of MRP as mediator of drug resistance seems unconvincing in this malignancy. MRP is located in the cytop... |
A power transformer is one of the most critical and expensive assets in electric power systems. Failure of a power transformer would not only result in a downtime to the entire transmission and distribution networks but may also cause personnel and environmental hazards due to oil leak and fire. Hence, to enhance a tra... |
A 63-year-old male patient with a mass in the left chest wall was referred to our hospital. An osteoclastic area was found in the mass of the left 4th rib by computed tomography; the mass was hard and little movable. There was an irregular and poorly demarcated low-density area, 5 cm in diameter, in the liver anterior ... |
We have carried out a Monte Carlo simulation of the conductivity of a two-dimensional strongly localized interacting system. A plot of dlog sigma /dlogT versus T, on a double logarithmic scale, clearly shows two distinct regimes, one activated at high T and a non-activated one at low T. The conductivity exponent in thi... |
The marketing is carried out by using various social media strategies and platforms like Facebook, Instagram, Twitter, Pinterest, LinkedIn, YouTube, etc. these are various platforms that are used for marketing.

For decades, sociological theory has documented how our lives are simultaneously produced through and against normative structures of sex, gender, and sexuality. These normative structures are often believed to operate along presumably “natural,” biological, and essentialized binaries of male/female, man/woman, and het... |
Abstract Issues related to the relationship between prices and values of goods have occupied the minds of economists since the beginnings of economic thought. These considerations concern both general issues and the direct, practical dimension of values. For the real estate market, the main value category considered an... |
