2 Staining Techniques and Microscopy While conventional histological staining methods have been established for decades, some for more than a century, immunohistochemical techniques are not yet routinely used in forensic diagnostics.
The hair matrix at the anagen stage showed no positive staining for these PKC isozymes.
The tumour exhibited a diffuse and intense positive cytoplasmic staining using a mouse monoclonal antirenin antibody, whereas renin staining in the juxtaglomerular apparatus from the nontumoural parts of the kidney was undetectable (Fig.

Histological examination and immunohistochemical staining revealed that the mass was composed mostly of cysts lined by respiratory epithelium, submucosal glands with goblet cells, and intervening nerve twigs.

Propidium iodide/Annexin V double staining revealed a pre-apoptotic cell population with extract-treated MCF10CA1a, T47D and BT-20 cells.
There was a varied increase in Drp1 staining in non-invasive ductal carcinoma in situ, which was much more intense in invasive breast carcinoma and metastases to lymph nodes.
This case shows the materials ability to achieve high esthetic multi layered results when combined with a simple External Staining technique.
After 2% OsO4 postﬁxation and 2% uranyl acetate en bloc staining, selected sections were dehydrated in graded acetone and ﬁnally embedded in Durcupan (Fluka, Buchs, Journal of Neuroscience Research NPY Interneurons Switzerland) resin.
Returning to Europe on holiday The year has been great. You have made the most of the wonderful country you are currently living in. The children have settled into their new schools and are happy. The school holidays arrive and you decide to return to Europe for a few weeks. In some cases you may decide to return to Europe for the summer or you may decide to send the children back to Europe to go to a summer camp or stay with their grandparents. You no longer think of malaria as you have left the infected region. You are wrong! The first symptoms of malaria appear between 7 days and 2 months (for the most deadly form) after the insect bite. The people in charge of your children (or you) will call a doctor if the children get a fever, sweat or have muscular pain. They/You may forget to mention that your children live abroad. The doctor may diagnose flu, a stomach ache or constipation. In the case of malaria, each day counts. Noone is safe ! Which is why, at the SLIGHTEST FEVER (even a very light one), you (grandparents, relatives, the childminder or even your children) MUST ABSOLUTELY CONSIDER THAT IT COULD BE MALARIA BEFORE CONSIDERING ANY OTHER DIAGNOSIS. If possible, go directly to the Accident and Emergency Department of the nearest hospital and ask for a blood test, peripheral smear study and/or a Quantitative Buffy Coat (QBC) (learn these names off by heart if necessary). We often hear about these tests without knowing what they are. Here are some simple explanations: ‐ The Peripheral Smear Test : Light microscopy of thick and thin stained blood smears remains the standard method for diagnosing malaria. It involves collection of a blood smear, its staining with Romanowsky stains and examination of the Red Blood Cells for intracellular malarial parasites. Thick smears are 20–40 times more sensitive than thin smears for screening of Plasmodium parasites. In falciparum malaria, parasites may be hidden in tissue capillaries resulting in a falsely low parasite count in the peripheral blood. In such instances, the developmental stages of the parasite seen on blood smear may help to assess disease severity better than parasite count alone. One negative blood smear makes the diagnosis of malaria very unlikely (especially the severe form); however, smears should be repeated every 6–12 hours for 48 hours if malaria is still suspected. 4 The smear can be prepared from blood collected by venipuncture, finger prick and ear lobe stab. In obstetric practice, cord blood and placental impression smears can be used. ‐ QBC : This is a new test that is very simple to use and can be bought in pharmacies. The test contains all of its staining agents within a single tube. Blood is collected by a finger prick and then centrifuged in the QBC centrifuge for 5 minutes. Since the tube has been concentrated by centrifugation, the malaria parasites will be concentrated and it can be quite simple and fast to get a result. If you are going to an isolated area, you should take a box of « COARTEM » or « RIAMET » or « LARIAM » or « MALARONE » in your suitcase, and follow the instructions as soon as even a small fever is detected, just in case. Go to your doctor before you leave. He will prescribe the anti‐malarial. But don’t think you needn’t go to your nearest emergency medical centre. You must get a test to have a quick and reliable diagnosis. 2.

Do not assume that staining around the exterior of the coolant pump body is due to a coolant pump leak.
and other clinical parameters - H&E staining demonstrated kidney tissues from from 85 patients.
Cell viability was assessed using Trypan blue staining solution and flow cytometry after diamidinophenylindol (DAPI) staining.
Staining of the incorporated PDGA substrate with methylene blue revealed a single prominent spot of enzymatic action corresponding to a protein of ∼ 30 kDa and pI 9.0.
Analysis of each SEC fraction with one-dimensional SDS-PAGE (1D-SDS-Gel) gave gels with very poor resolution, and showed minute amounts of low–molecularweight (MW) proteins, as determined by Coomassie blue staining method (Supporting Information Fig.
The liver biopsies were placed in buffered formalin and stained with haematoxylin and eosin or with Gomori methenamine silver for reticulum staining.
(Rhodes et al., 2003) examined brain activity patterns of HVR mice versus control lines through c-fos staining and determined that high neuron activation in the NAc differentiated running motivation between the HVR and control lines.
