DCM-72 (dexterity, cutaneous, and muscle-72): A composite scoring system for objective assessment of upper limb dysfunction in patients with degenerative cervical myelopathy.

Background Context: Degenerative cervical myelopathy (DCM) is characterized by spinal cord compression, which can present with limb weakness and numbness, loss of fine motor skills, gait disturbance, and bladder dysfunction. The modified Japanese Orthopedic Association (mJOA) and Graded Redefined Assessment of Strength, Sensibility, and Prehension Version Myelopathy (GRASSP-M) scores evaluate distinct aspects to assess the severity of upper and lower extremity dysfunction. Our study aims to develop an integrative, multidimensional Dexterity, Cutaneous, and Muscle (DCM-72) scoring system to provide a more comprehensive and objective evaluation of upper extremity functional impairment.

Spinal cord swelling and intradural compression predict neurological recovery after acute cervical traumatic spinal cord injury.

Intradural spinal cord compression impairs perfusion pressure and is putatively rate-limiting for recovery after traumatic spinal cord injury (tSCI). After cervical tSCI, even minimally improved tissue preservation may help promote neurological recovery. To assess the nature and extent of spinal cord swelling and compression post-acute cervical tSCI, we evaluated several baseline MRI parameters including BASIC score, intramedullary lesion (IML) length, maximal canal compromise (MCC), maximal spinal cord compression (MSCC), extent of cord compression (ECC), maximal swollen anteroposterior diameter adjacent to injury site (Dmax), and maximal cord swelling (MCS) in 169 consecutive patients across 2 centers.

Design and protocol for the decompression-plus trial: a phase 1 clinical study of dorsal myelotomy and expansive duroplasty with or without autologous nerve grafting in acute traumatic spinal cord injury.

Background: Traumatic spinal cord injury (tSCI) is a devastating condition marked by persistent neurologic deficits. Secondary injury processes following tSCI, including progressive hemorrhagic necrosis and elevated intraspinal pressure (ISP), contribute to ongoing neurologic deterioration. Existing therapeutic strategies have shown limited efficacy, emphasizing the critical need for innovative interventions.

Modeling the spatial relationship between landscape services and vulnerability assessment.

Even though many studies have been thus far devoted to landscape services (LS) or vulnerability assessment (VA) alone, the relationship between these two concepts has been less investigated. The current study attempts to model the spatial relationship between LS and VA in the Tarhan area (west of Iran). For this purpose, a combination of the analytic hierarchy process (AHP), remote sensing (RS), and geographic information system (GIS) techniques are applied to assess vulnerability.

Modeling land use/cover change based on LCM model for a semi-arid area in the Latian Dam Watershed (Iran).

The monitoring and modeling of changes, based on a time-series LULC approach, is fundamental for planning and managing regional environments. The current study analyzed the LULC changes as well as estimated future scenarios for 2027 and 2037. To achieve accuracy in predicting LULC changes, the Land Change Modeler (LCM) was used for the Latian Dam Watershed, which is located approximately in the northeast of Tehran.

MicroRNA and Exosome in Retinal-related Diseases: Their Roles in the Pathogenesis and Diagnosis.

The precise and exquisite architecture of the retina is directly related to vision. Therefore, any mechanisms associated with disruption of retinal structure could affect the quality of vision. A large number of studies indicated that several cellular and molecular processes are involved in retina pathogenesis.

The association between HPV gene expression, inflammatory agents and cellular genes involved in EMT in lung cancer tissue.

Background: Lung cancer is a leading cause of cancer morbidity and mortality worldwide. Several studies have suggested that Human papillomavirus (HPV) infection is an important risk factor in the development of lung cancer. In this study, we aim to address the role of HPV in the development of lung cancer mechanistically by examining the induction of inflammation and epithelial-mesenchymal transition (EMT) by this virus.

Exosomal microRNAs: novel players in cervical cancer.

Cervical cancer ranks fourth for both mortality and morbidity in women globally. Exosomes are considered as extracellular vesicles, secreted continuously by many cells with a size range from 30 to 150 nm. Exosomes can encapsulate microRNAs (miRNAs) and release them for cellular communications.

Expression of circulating miR-17, miR-25, and miR-133 in breast cancer patients.

One of the most lethal cancers among women is breast cancer. MicroRNAs (miRNAs) can be of great importance in the early detection of breast cancer. This study aimed to investigate some miRNAs in the serum of patients with breast cancer compared with the control group.

Melanoma: Where we are and where we go.

Melanoma is known as an aggressive tumor which shows an increasing incidence and poor prognosis in the metastatic phase. Hence, it seems that diagnosis and effective management (including early diagnosis, choosing of the effective therapeutic platform, caring, and training of patients for early detection) are major aspects of melanoma therapy. Early detection of melanoma is a key point for melanoma therapy.

Association of the genetic polymorphisms in immunoinflammatory microRNAs with risk of ischemic stroke and subtypes in an Iranian population.

Stroke is one of the most common type of cerebrovascular disease threatening human health and life with high mortality, disability, and morbidity. Ischemic stroke (IS) is determined to be a complex disease containing a group of heterogeneous disorders with various environmental and genetic risk factors. This study evaluated the polymorphisms of microRNAs involved in inflammatory routes leading to stroke in an Iranian population.

Disaster Management Structure of Universities: Case Study of the Central Campus of the University of Tehran.

Objective: Research on the disaster management plans of renowned universities worldwide shows that such plans are generally compiled in 3 categories: structural, nonstructural, and organizational sections. The importance of earthquakes in Tehran and the high vulnerability of the University of Tehran to earthquakes encouraged us to challenge the university's plans concerning disaster management.

Methods: An initial attempt was made to analyze the disaster management of 23 renowned universities worldwide and their structure compared with the present organizational structure of the University of Tehran.
