1. Dakin's hypochlorite solution has the power of dissolving necrotic tissue, pus, and plasma clot in the concentration and reaction used clinically. 2. Chloramine-T and dichloramine-T do not exhibit this action. 3. The solvent action of Dakin's hypochlorite solution of the degree of alkalinity used clinically is due primarily to its hypochlorite content, but its slight alkalinity, while in its...

Regeneration (revitalization) of infected necrotic pulp tissue has been an important issue in endodontics for more than a decade. Based on a series of case reports, there appears to be evidence that new soft tissue can enter the root canal with a potential for subsequent hard tissue deposition resulting in a narrowing of the root canal. Very little is presently known about the exact nature of t...

Identification of necrosis in tumors is of prognostic value in treatment planning, as necrosis is associated with aggressive forms of cancer and unfavourable outcomes. To facilitate rapid detection of necrosis with Mass Spectrometry (MS), we report the lipid MS profile of necrotic breast cancer with Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) imaging validated with statistica...

Necrosis is induced by ischemic conditions within the core of many solid tumors. Using fluorescent fusion proteins, we provide in vivo evidence of histone trafficking among cancer cells in implanted tumors. In particular, the most abundant H1 isoform (H1.2) was found to be transported from necrotic tumor cells into surrounding viable cells where histones are selectively taken up by energy-depen...

BACKGROUND In this study, we aimed to establish the rabbit VX2 limb tumor model, and then prepare a "necrotic zone" as a safe margin by volumetric modulated arc therapy and simultaneous integrated boost (VMAT-SIB) technique applied in the areas where the tumor is located adjacent to the bone (GTVboost area). MATERIAL AND METHODS Rabbits in the control group (n=10) were not treated, while thos...

BACKGROUND The purpose of this study was to assess MRI criteria for detecting residual malignant head and neck squamous cell carcinoma (HNSCC) nodes after chemoradiotherapy (CRT). METHODS One hundred and six metastatic nodes were assessed 6 weeks posttreatment by MRI for necrosis, extranodal neoplastic spread (ENS), size, and percentage of size change. Size measurements were reanalyzed after ...

With our aging population, chronic diseases that compromise skin integrity such as diabetes, peripheral vascular disease (venous hypertension, arterial insufficiency) are becoming increasingly common. Skin breakdown with ulcer and chronic wound formation is a frequent consequence of these diseases. Types of ulcers include pressure ulcers, vascular ulcers (arterial and venous hypertension), and ...

Necrotizing fasciitis is an uncommon but life-threatening infection primarily involving the superficial fascia. Note the blue-gray color change of the vulvar skin lateral to areas of ulceration (A), The superficial fascia of the vulva is in continuity with that of the anterior abdominal wall. This incision reveals normal-appearing subcutaneous tissue in its superior aspect compared to the dull ...

BACKGROUND Experimental studies suggest that low wall shear stress (WSS) promotes plaque development and high WSS is associated with plaque destabilization. We hypothesized that low-WSS segments in patients with coronary artery disease develop plaque progression and high-WSS segments develop necrotic core progression with fibrous tissue regression. METHODS AND RESULTS Twenty patients with cor...

Tuberculosis (TB) is a chronic infectious disease caused by Mycobacterium tuberculosis (Mtb) that in most cases induces irreversible necrosis of lung tissue as a result of excessive inflammatory reactions. The murine model of TB in resistant C57BL/6 mice infected with reference Mtb strains is widely used in TB studies; however, these mice do not show a necrotic pathology, which restricts their ...
