A Colorimetric Distinct Color Change Cu(II) 4-{[1-(2,5-dihydroxyphenyl)ethylidene]amino}-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one Chemosensor and its Application as a Paper Test Kit.

In the current research work "4-{[1-(2,5-dihydroxyphenyl)ethylidene]amino}-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one" chemosensor (C1) synthesized by condensation reaction using "4-amino-1,2-dihydro-1,5-dimethyl-2-phenylpyrazol-3-one" and "2,5-dihydroxy actophenone" was used as the effective sensor of metal ion. The C1 shows absorption peak at 326 nm due to the C = C bond (π-π* transition), while the absorption peak at 364 nm is caused by the C = O bond (n-π* transition). In the presence of copper, C1 only demonstrated a redshift in absorption peak from 364 to 425 nm.

A Multistep Tumor Growth Model of High-Grade Serous Ovarian Carcinoma Identifies Hypoxia-Associated Signatures.

High-grade serous ovarian carcinoma (HGSC) is associated with late-stage disease presentation and poor prognosis, with a limited understanding of early transformation events. Our study analyzes HGSC tumor progression and organ-specific metastatic dissemination to identify hypoxia-associated molecular, cellular, and histological alterations. Clinical characteristics of the HGSC were replicated in orthotopic xenografts, which involve metastatic dissemination and the prevalence of group B tumors (volume: >0.

Recurrent Meningeal Melanocytoma of Cervical Spine: A Rare Case.

Melanocytomas of the central nervous system are rare benign or intermediate grade localized melanocytic tumors. Despite its benign nature, it can follow a locally aggressive course with propensity to recur. We present the case of a 29 years old female who presented with a recurrent lesion in cervical spine and rapidly progressing quadriparesis.

Adsorption of Congo Red on Pb doped FeO: experimental study and theoretical modeling via double-layer statistical physics models.

Size-controlled PbFeO nanoparticles (Pb-FeONPs) were fabricated by the thermal co-precipitation method and characterized by FE-SEM, EDX, XRD, and IR techniques. The SEM and XRD images showed the average size distribution and average crystallite size of 19.21 nm and 4.

A Mini Review on Organic Chemosensors for Cation Recognition (2013-19).

Colorimetric and ratiometric fluorescent probe for cations gain very well attention by the chemist, biologist and environmentalist. Metals has two sides, first is biolgical active for living creature and toxic nature for the ecosystem. From last three decades the scientists are contiously trying to find out the best solution for the detection of cations at micro as well as nanomolar levels.

Ability of Spine Specialists to Identify Psychosocial Risk Factors as Obstacles to Recovery in Patients with Low Back Pain-Related Disorders.

Study Design: Prospective study.

Purpose: Yellow flags are psychosocial associated with a greater likelihood of progression to persistent pain and disability. These are referred to as obstacles to recovery.

Clinical Stratification of High-Grade Ovarian Serous Carcinoma Using a Panel of Six Biomarkers.

Molecular stratification of high-grade serous ovarian carcinoma (HGSC) for targeted therapy is a pertinent approach in improving prognosis of this highly heterogeneous disease. Enabling the same necessitates identification of class-specific biomarkers and their robust detection in the clinic. We have earlier resolved three discrete molecular HGSC classes associated with distinct functional behavior based on their gene expression patterns, biological networks, and pathways.

Recurrent thoracic intramedullary schwannoma: report of two cases with long term follow up.

Occurrence of intramedullary schwannomas is rare as Schwann cells are generally present in the nerve root and not in the spinal cord. To date, approximately around 60 cases of intramedullary schwannoma in patients without neurofibromatosis have been reported in the English literature, of which only eight were children. We describe two cases of thoracic intramedullary schwannomas that recurred after primary excision.

Application and use of subcutaneous stay sutures in anterior cervical spine surgeries with a transverse neck incision: A technical report.

Objective/purpose: The objective of this study is to describe our experience with the use of stay sutures and transverse neck incision for anterior cervical spine surgeries involving multiple levels.

Summary Of Background Data: Transverse incisions on neck usually heal with minimal fibrosis resulting in cosmetically acceptable scars whereas vertical incision, although provides greater exposure, heals with extensive fibrosis resulting in ugly scars. Transverse incision is thus highly recommended.

Radiographic Incidence of Lumbar Spinal Instability in Patients with Non-spondylolisthetic Low Backache.

Introduction Radiological lumbar spinal instability may exist without obvious spondylolisthesis. We aim to determine the incidence of this non-spondylolisthetic cause of instability in conservatively managed patients and operated groups of patients. We also attempted to study the relationship between instability and its occurrence with respect to age, sex, signs and symptoms.

Impalement Injury to Thigh: A Case Report with Review of Literature.

Introduction: Impalement injuries are one of the rare presentations in the emergency department and present complex surgical challenges in management. Prompt transfer to tertiary centre, pre-operative planning, and multi specialty involvement is crucial in the management of such cases.

Case Report: We report a case of 18-year-old male who sustained impalement injury to thigh with an iron rod after falling from height.

Traumatic multiple cervical spine injuries in a patient with osteopetrosis and its management.

Study Design: Single case report.

Objective/purpose: To report multiple level fractures of cervical spine in a patient with osteopetrosis and its management. Osteopetrosis is a rare inherited condition characterized by defective remodeling resulting in hard and brittle bones with diffuse osteosclerosis.

Minimally Invasive Treatment of a Complex Tibial Plateau Fracture with Diaphyseal Extension in a Patient with Uncontrolled Diabetes Mellitus: A Case Report and Review of Literature.

Fractures of the proximal tibia comprise a huge spectrum of injuries with different fracture configurations. The combination of tibia plateau fracture with diaphyseal extension is a rare injury with sparse literature being available on treatment of the same. Various treatment modalities can be adopted with the aim of achieving a well-aligned, congruous, stable joint, which allows early motion and function.

Clinico-pathological spectrum of primary ovarian malignant mixed mullerian tumors (OMMMT) from a tertiary cancer institute: A series of 27 cases.

Aims And Objectives: To study the clinico-pathological characteristics of primary ovarian malignant mixed mullerian tumor (OMMMT) and assess the prognostic factors associated with treatment outcome and survival.

Materials And Methods: The pathology database was searched for primary ovarian carcinosarcoma diagnosed and/or managed at our institute from period of January 2004 to July 2010. The histological sections were reviewed, with emphasis on type and grade of epithelial and sarcomatous components.

Phosphaturic mesenchymal tumor with chondromyxoid fibroma-like feature: an unusual morphological appearance.

Phosphaturic mesenchymal tumor (PMT) is a rare and distinctive tumor almost always associated with oncogenic osteomalacia. This tumor is often misdiagnosed due to its widely varied histomorphological spectrum. More recently the term PMT or its variants has been used whatever the histomorphological features.
