Vahid Mohsenin
BACKGROUND: Acute kidney injury (AKI) is a common complication in critically ill patients and is associated with high morbidity and mortality. This paper provides a critical review of the etiologies of AKI and a systematic approach toward its diagnosis and management with emphasis on fluid volume assessment and the use of urine biochemical profile and microscopy in identifying the nature and the site of kidney injury. MATERIALS AND METHODS: The search of PubMed and selection of papers had employed observational designs or randomized control trials relevant to AKI...

Due to the limited capacity of working memory (WM), efficient suppression of no longer relevant memory contents (inhibition) and revising the current contents of the memory (updating) are crucial factors in memorizing. However, not every individual is able to do so; among them are post-traumatic stress disorder (PTSD) patients who seem to have trouble forgetting trauma-related materials, making their memory overloaded with irrelevant information. The present study assumes that the inability to forget in PTSD patients is due to the impaired updating function of WM and, therefore, suggests that these individuals have inferior WM function for both emotional and unemotional materials...

BACKGROUND: Methadone maintenance therapy (MMT) is provided to patients with opioid use disorder (OUD). However, as with all opioids, methadone impacts negatively on sexual function. To counter this, Rosa Damascena oil (RDO) has been used successfully for opioid-dependent male patients under MMT and with methadone-related sexual dysfunction (MRSD). In the present study, we tested the possible influence of RDO on sexual function and sex hormones of opioid-dependent female patients undergoing MMT and with MRSD...

N,N'-methylenebis(acrylamide) (MBA)-crosslinked poly(acrylic acid) (PAA) particles with low degree of crosslinking were synthesized using distillation precipitation polymerization (DPP). Size and size distribution of particles were obtained using DLS and FE-SEM and results showed that microspheres had a narrow size dispersity. (1) H NMR results indicated that amount of crosslinker in structure of particles is a little more than the molar percentage of feeded MBA due to greater activity ratio of MBA than AA...

There is a rapidly growing interest in generation of 3D organotypic microtissues with human physiologically relevant structure, function, and cell population in a wide range of applications including drug screening, in vitro physiological/pathological models, and regenerative medicine. Here, we provide a detailed procedure to generate structurally defined 3D organotypic microtissues from cells or cell spheroids using acoustic waves as a biocompatible and scaffold-free tissue engineering tool.

A local field potential (LFP) signal is an alternative source to neural action potentials for decoding kinematic and kinetic information from the brain. Here we demonstrate that better extraction of force-related features from multichannel LFPs improves the accuracy of force decoding. We propose that applying canonical correlation analysis (CCA) filter on the envelopes of separate frequency bands (band-specific CCA) seperates non- task related information from the LFPs. The decoding accuracy of the continuous force signal based on the proposed method were compared with three feature reduction methods: 1) Band-specific principal component analysis (bandspecific PCA) method that extract the components which leads to maximum variance from envelopes of different frequency bands, 2) Correlation coefficient-based (CC-based) feature reduction that selects the best features from the envelopes sorted based on the absolute correlation coefficient between each envelope and the target force signal and 3) Mutual information -based (MI-based) feature reduction that selects the best features from the envelopes sorted based on the mutual information between each envelope and output force signal...

In this paper we designed and fabricated a metasurface working as a radar cross section (RCS) reducer over an ultra wide band of frequency from 3.8 to 10.7 GHz. The designed metasurface is a chessboard-like surface made of alternating tiles, with each tile composed of identical unit cells. We develop a novel, simple, highly robust and fully automated approach for designing the unit cells. First, a topology optimization algorithm is used to engineer the shape of the two unit cells. The area of each unit cell is pixelated...

BACKGROUND: Cystic echinococcosis (CE) is a zoonotic disease with global prevalence, which causes considerable health problems and economic losses throughout the world. The aim of this study was to assess the seroepidemiology of CE in Doroud City, Lorestan Province, Iran, considered a neglected endemic location. METHODS: An ELISA was performed using recombinant AgB from Apr to Jul 2015 in Lorestan Province, Western Iran. The commercial Hydatidosis IgG ELISA kit (Vircell SL, Granada, Spain) was used to confirm the obtained results...

Free and cellulose nanocrystals (CNC)-grafted block copolymers of acrylic acid and N-isopropylacrylamide with various poly (N-isopropylacrylamide) (PNIPAAm) block lengths as dual temperature- and pH-sensitive materials were synthesized by RAFT polymerization via an R-approach method. Controlling LCST of the products by changing the PNIPAAm block length, addition of CNC, and variation of pH was studied. The free and CNC-grafted block copolymers were analyzed by Fourier transform infrared and proton nuclear magnetic resonance...

Curcumin has been proven to be an effective herbal derived anti-inflammatory and antioxidant biocompatible agent. In this research PLGA (as a biocompatible and GRAS polymer) nanoparticles containing Curcumin were electrospryed from different polymeric solutions with different concentrations for the first time. Morphology of these nanoparticles in the absence/presence of Curcumin was evaluated by SEM, TEM and XPS analyses. Perfectly shaped nanoparticles with an average size of 300 and 320 nanometers were observed for neat and Curcumin loaded PLGA, respectively...

This review article summarises the possible mechanisms of the protein-ligand interaction, folding, misfolding, aggregation and inhibition of protein aggregates. Under certain stressed condition the folding process deviates from its path and results into misfolding and aggregation of proteins. So aggregates have to be inhibited in order to cure the diseases. In some cases of protein-ligand interaction studies we have seen that the interaction of a protein with more than one ligand may show both type of quenching mechanisms i...

BACKGROUND: Cancer lethality is mainly caused by metastasis. Therefore, understanding the nature of the genes involved in this process has become a priority. BACH1, a basic leucine zipper transcription factor, has been shown to transcriptionally regulate expression of a range of genes that are associated with breast cancer metastasis. However, the exact role and the underlying molecular mechanism of BACH1 in prostate cancer remain unclear. This study aims to explore the expression of BACH1 in prostate cancer tissues and the effect of BACH1 suppression on prostate cancer cell behavior...

Mutations in TET2, encoding one of the TET members responsible for the conversion of DNA cytosine methylation to hydroxymethylation (5-hmc), have been recently described in Human T-lymphotropic virus type 1-associated adult T-cell leukemia/lymphoma (ATLL). However, neither the amount of genomic 5-hmc in ATLL tumor cells nor TET2 expression has been studied yet. In this study, we analyzed these two parameters as well as the mutational status of TET2 in ATLL patients. By employing a direct in situ approach, we documented that tumor T cells infiltrating lymph nodes exhibit low level of 5-hmc compared to residual normal T cells...

The adult mammalian heart possesses only limited capacity for innate regeneration and the response to severe injury is dominated by the formation of scar tissue. Current therapy to replace damaged cardiac tissue is limited to cardiac transplantation and thus many patients suffer progressive decay in the heart's pumping capacity to the point of heart failure. Nanostructured systems have the potential to revolutionize both preventive and therapeutic approaches for treating cardiovascular disease. Here, we outline recent advancements in nanotechnology that could be exploited to overcome the major obstacles in the prevention of and therapy for heart disease...
