We describe the case of a 52 year old male presenting with subacute headache. Cranial imaging suggested haemorrhage into a parietal, partially intraventricular, space occupying lesion. The radiology was interpreted to be most consistent with a glioblastoma. The lesion was near totally resected. The histopathology was a WHO grade 1 schwannoma.

In the epipelagic ocean the genus Oithona is considered as one of the most abundant and widespread copepods and plays an important role in the trophic food web. Despite its ecological importance, little is known about the Oithona and cyclopoid copepods genomics. Therefore, we sequenced, assembled and annotated the genome of Oithona nana. The comparative genomic analysis integrating available copepod genomes highlighted the expansions of genes related to stress response, cell differentiation, and development, including genes coding Lin12-Notch-Repeat (LNR) domain proteins...

Importance: Controversy exists around the American Joint Committee on Cancer (AJCC) TNM staging system for medullary thyroid cancer (MTC). Because of the rarity of the disease and limited available data, the staging system for MTC has been largely extrapolated from staging for differentiated thyroid cancer. Objectives: To evaluate how well the current (seventh and eighth editions) AJCC TNM staging system correlates with survival for patients with MTC and to suggest a possible revision...

Memristive devices are promising circuit elements that enable novel computational approaches which go beyond the von-Neumann paradigms. Here by tuning the chemistry at the Al-LaNiO3 (LNO) interface, a metal-metal junction, we engineer good switching behavior with good electroresistance (ON-OFF resistance ratios of 100), and repeatable multiple resistance states. The active material responsible for such a behavior is a self-formed sandwich of an AlxOy layer at the interface obtained by grabbing oxygen by Al from LNO...

INTRODUCTION: Elevated plasma homocysteine (Hcy) levels have been associated with several tissue injuries including heart and liver fibrosis. In these diseases, hyperhomocysteinemia (Hhcy) plays a major role in modulating the alteration of the balance between matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMPs), leading to the pathological accumulation of extracellular matrix (ECM) proteins. Since the effect of Hhcy on ECM of seminal vesicle was not studied, the aim of our research was to check if Hcy can induce a remodeling within seminal vesicles ECM...

Three new cembrene diterpenoids, sarcoehrenbergilid A-C (1-3), along with four known diterpenoids, sarcophine (4), (+)-7α,8β-dihydroxydeepoxysarcophine (5), sinulolide A (6), and sinulolide B (7), and one steroid, sardisterol (8), were isolated and characterized from a solvent extract of the Red Sea soft coral Sarcophyton ehrenbergi. Chemical structures were elucidated by NMR and MS analyses with absolute stereochemistry determined by X-ray analysis. Since these isolated cembrene diterpenes contained 10 or more carbons in a large flexible ring, conformer stabilities were examined based on density functional theory calculations...

In this paper, a cell selection technique for millimeter-wave (mm-wave) cellular systems with hybrid beamforming is proposed. To select a serving cell, taking into account hybrid beamforming structures in a mm-wave cellular system, the angles of arrival and departure for all candidate cells need to be estimated in the initialization stage, requiring a long processing time. To enable simultaneous multi-beam transmissions in a multi-cell environment, a cell and beam synchronization signal (CBSS) is proposed to carry beam IDs in conjunction with cell IDs...

There is an increasing concern over male reproductive toxicity caused by lead exposure. Folic acid (FA) is supposed to be a promising therapeutic strategy against lead toxicity. Therefore, the aim of this experimental study was to shed light on the potential protective role of FA on lead-induced testicular dysfunction in rats and its possible underlying mechanistic pathways. Rats (n = 24) were divided into four groups: Control, FA, Lead, and FA+Lead group. After 4 weeks, lead intoxication resulted in a marked reduction in the relative testicular weight and the serum level of testosterone, an impairment in the characters of semen analysis, and an increased content of lead, malondialdehyde and both interleukin-6 and -10 and a decreased antioxidant enzyme levels in the testicular tissue homogenate...

BACKGROUND: Debate around the value of laboratory tests in establishing the diagnosis of acute appendicitis (AA) still continues. This prospective study aimed to investigate the changes in mean platelet volume (MPV), platelet distribution width (PDW), and red cell distribution width (RDW) with the diagnosis of acute appendicitis. METHOD: 200 patients who underwent emergency appendectomy were included. According to postoperative histology, patients were divided into three groups: acute non-complicated, acute complicated appendicitis (positive appendicectomy groups), and negative appendectomy group...

Noble and precious metal catalysts are sought for their remarkable efficiency in catalyzing numerous reactions in heterogeneous phase. However, they are costly and request the development of high surface area supports that favor their strong immobilization, dispersion and stability. Towards this end, mesoporous silica-based materials can be regarded as unique supports for nanometric-sized noble metal catalysts provided they are functionalized with appropriate ligands. In this work, mesoporous silica SBA-15 was prepared and modified with 3-azidopropyltriethoxysilane then clicked with alkyne derivatives of 1,3,5-triazines complex ligand...

A novel marine fungus was isolated and classified as Aspergillus flavus strain EGY11. The heat-inactivated form of isolated Aspergillus flavus was investigated and evaluated as a new eco-friendly and highly efficient biosorbent for removal of toxic heavy metals such as Cd(II), Hg(II), and Pb(II) from aqueous solutions. The SEM morphological studies of biosorbent-loaded metal ions confirmed their direct binding on the surface of heat-inactivated Aspergillus flavus. The metal biosorption capacity values were determined and optimized by the batch technique in the presence of various experimental controlling factors such as pH, contact time, biosorbent dosage, initial metal ion concentration, and coexisting species...

BACKGROUND: Non-technical skills (NTS) are being increasingly recognised as vital for safe surgical practice. Numerous NTS rating systems have been developed to support effective training and assessment. Yet despite the additional challenges posed by robotic surgery, no NTS rating systems have been developed for this unique surgical environment. This study reports the development and validation of the first NTS behavioural rating system for robotic surgery. METHODS: A comprehensive index of all relevant NTS behaviours in robotic surgery was developed through observation of robotic theatre and interviews with robotic surgeons...

Squamous cell carcinoma (SCC) of the colon without known primary source is a rare finding that needs aggressive management. We report two cases of SCC of the colon without any clear extra-colonic source despite extensive workup. In our experience, the clinical course and prognosis are largely dependent on the presence of metastatic disease at diagnosis. The main treatment is surgery, with chemotherapy having less defined role.

Metalloproteinases (MMPs) contribute to tissue remodeling and acute inflammation not only by degrading extracellular matrix proteins but also by controlling the influx of chemokines through the regulation and shedding of syndecans. B-lymphocytes, in addition to their well-known function as antibody producing cells, participate in the innate immune response by secreting inflammatory cytokines and chemokines. However, there is little information about the role of B-lymphocytes in the regulation of MMPs; consequently, herein we investigated whether activated human circulating B-lymphocytes contributed to the secretion of MMPs...
