A self-healable metallohydrogel for drug encapsulations and drug release.

A self-healable metallohydrogel (MOG) of Mn(ii) has been prepared using a low molecular weight gelator, NaHL {HL = l-(3,5-di--butyl-2-hydroxy-benzyl)amino aspartic acid}. The MOG has been characterized by MALDI TOF mass spectrometry, rheological studies, IR spectroscopy, and microscopic techniques. Non-steroidal anti-inflammatory drug (NSAID), indomethacin (IND) and anti-cancer drug gemcitabine (GEM) were encapsulated into the metallohydrogel.

Scintigraphic Evaluation of Decontamination Lotion for Removal of Radioactive Contamination From Skin.

Objective: Skin contamination is one of the most likely risks after accidental or occupational radiological accidents. Using scintigraphy, we assessed a topical lotion for its decontamination efficacy (DE) after exposure with short-lived medical radioisotopes technetium Tc 99m (Tc) and thallium 201Tl (Tl).

Methods: Using Tc (300 ± 5 μCi/100 μl) and Tl (100 ± 5 μCi/100 μl), the thoracoabdominal region (shaved skin) of Sprague Dawley rats and human tissue equivalent were contaminated and then decontaminated using cotton swabs soaked in formulated lotion at different time intervals.

Decontamination of human and rabbit skin experimentally contaminated with 99mTc radionuclide using the active components of "Shudhika"-a skin decontamination kit.

Introduction: Radioactive contamination can occur as a result of accidental or intentional release of radioactive materials (RM) into the environment. RM may deposit on clothing, skin, or hair. Decontamination of contaminated persons should be done as soon as possible to minimize the deleterious health effects of radiation.

Pancake kidney detected on renal scintigraphy.

Pancake kidney is an extremely rare renal anomaly resulting from abnormal renal ascent and subsequent fusion. The authors describe a patient with pancake kidneys detected on a Tc-99m DTPA scan. The case reported depicts the scintigraphic findings in such a patient having a pancake kidney.
